《Apexlegends》游戏简论(二)
在此主要向读者介绍《Apex legends 》游戏的人物模型机制，以及玩家在游玩中可以选择的另外4种角色。
HitboxHitbox 指：游戏中，各贴图的击中判定模型。
当射击Hitbox 时，视为击中目标。
在《Apex 》中，不同的传奇有着不同的Hitbox ，玩家在使用一部分传奇时，非常容易被敌人击中。
导致一些传奇虽然有着非常实用的技能，但玩家却很少在游戏中选择这名传奇。
通过对国内外论坛及视频查询并测试后得到结果如下：人物的Hitbox 从小到大依次是：恶灵、寻血猎犬、生命线、幻象、班加罗尔、探路者、侵蚀和直布罗陀，数值上，以恶灵为基准，各传奇约为：寻血猎犬、生命线=恶灵×112%幻象、班加罗尔=恶灵×133%探路者=恶灵×190%侵蚀=恶灵×205%直布罗陀=恶灵×240%班加罗尔充能时间：270秒命脉命脉是一名战地医护兵，相对于其他传奇，她可以更安全地救助队友，并且治疗他们。
被动技能———战斗医疗兵：更快地扶起被击倒的队友，并且救治期间在正面撑起一个无敌的护盾、使用治疗道具使用速度提高25%。
战术技能———D.O.C.治疗机器人：拿出一个治疗机器人，机器人会自动持续治疗附近的所有玩家。
绝招———空投舱：在空地上呼叫一个空投箱，空投内随机出现3个装备。
需要注意的是，呼叫空投后，附近的玩家也将会看到空投，使用者需要选择合适的时间呼叫，以免暴露自己。
直布罗陀直布罗陀是一名防护型的传奇，但需要注意的是，他的体型是游戏目前最为巨大的，非常容易被击中，玩家在使用的时候需要非常注意走位。
被动技能———枪盾：在瞄准时将部署枪盾，枪盾无法遮挡头部，护盾值约为80。
战术技能———保护圆顶：投放圆顶防护罩持续15秒，护盾半透明，所有伤害均无法穿过两侧护盾。
绝招———防御性轰炸：玩家使用烟雾手榴弹标记地点，该地点将在数秒后遭到迫击炮打击。
侵蚀腐蚀是游戏中唯一能放置陷阱的传奇。

This system is completely redesigned and features a new CCD detector, based upon a 4K CCD chip. It also incorporates a new goniometer with an enhanced interface, all enclosed in a fail-safe X-ray enclosure system.From a software and operational viewpoint, the SMART APEX system shares many common features with its predecessors (SMART 1K, SMART 2K, SMART 1000, SMART 2000, SMART 1500, SMART 6000, and SMART 6500). These features are discussed in the SMART Reference Manual. Also, most of the information in the current SMART, SAINT, and ASTRO manuals applies to the SMART APEX system and the other SMART CCD systems.From a hardware viewpoint, the SMART APEX also shares common hardware components. Other members of this new generation of instruments include the D8 ADVANCE and D8 DISCOVER, and the D8 GADDS systems for general diffraction. Documentation on some of these common hardware and software components is available in the user’s manuals for the D8 family of instruments.1.2 How to Use This ManualThis manual covers basic tutorial steps to get you started using the SMART APEX X-ray diffractometer system.The manual leads you step-by-step through an actual data collection and structure determination experiment performed on a typical system. Additional reference is made (where necessary) to related program manuals (SMART, SAINT, ASTRO, and SHELXTL), appendices, other factory documentation, and standard crystallographic reference materials. And special notes are included where new users tend to have problems.Information is organized in this manual as follows:• Section 1, Introduction, presents system features and instructions on using thismanual.• Section 2, Software Overview, provides details on the software used with thesystem.1 IntroductionM86-E02015 -08001-1Introduction SMART APEX User ’s Manual1-2M86-E02015 -0800• Section 3, Hardware Overview, provides details on the system configuration for those not familiar with the equipment.Included is a brief description of each component as well as options available with the system.•Section 4, Data Collection, describes basic operation of the hardware and software of the SMART APEX system to collect single crystal X-ray diffraction data. Procedural steps are presented in a typical fashion that you would use to analyze an unknown sample.•Section 5, Data Integration, explains how to convert the raw frame data to a set of integrated intensities that can be used to solve and refine the crystal structure. This section will illustrate use of theSAINTPLUS interface program to carry out integration of a data set previously collected in Section 4.•Section 6, Structure Determination &Refinement, demonstrates how to use the reduced intensity data to produce a crystal structure. The SHELXTL suite of crystallographic programs will be described.Examples in this manual use the specimen sample 2-dimethylsulfuranylidene-indan-1, 3-dione (YLID)1, similar to the crystal provided with your system. By using a similar sample,you can duplicate the procedures described in this manual and obtain similar results to assure your understanding of the SMART programs. (That is, your results should match those outlined in this manual except for minor variations caused by slight differences in specimens or instrument parameters.)Note : Before using this manual, ensure that the system is in proper working condition (e.g.the X-ray tube is aligned) and that all software has been properly installed.The essential software components of the SMART APEX system (located in the Bruker AXS program folder on your Windows NT desktop) are:SMART program This on-line programcontrols the instrument tocollect the experimentaldata used by the otherprograms in the systemprogram suite.SMART program This off-line versionperforms many datadisplay and manipulationfunctions but cannotcontrol the instrument.

SMART APEX system componentsM86-E02015 -08003-1Hardware Overview SMART APEX User ’s Manual3-2M86-E02015 -0800Radiation safety enclosure with interlocks and warning lightsA common component of all systems in the D8 family is the radiation safety enclosure.This new design is fully leaded (leaded metal sides and panels, leaded windows) to protect you from stray radiation. The enclosure also includes warning lamps (a governmentrequirement) that alert you when X-rays are being generated. And, as a special feature,the enclosure incorporates interlocks (for both hardware and software)—an automaticsystem-interruption device that senses when the doors and panels are open and prevents use of the shutter and data collection until you close the doors.D8 controllerThe D8 controller is an electronic module enclosed in the rack behind the font panel of the instrument. It contains all of the electronics and firmware for driving goniometer angles, opening the X-ray shutters, and monitoring other instrumentfunctions, such as safety interlocks, generator status, and detector statuses.Refrigerated recirculator for SMART APEX detectorThe refrigerated recirculator uses Peltiertechnology to cool the CCD chip to a required -40° C to minimize dark currents.ComputerIncluded with the system is a high-speed computer, which is used for control of the experiment, storage of raw frame data,integration of data, and solution andrefinement of the structure. The computeruses the Microsoft Windows NT ®operating system and includes the software described in Section 2. Often the computer is attached to a network of similarly configured computers with access to local and/or network printers.SMART APEX User ’s Manual Hardware OverviewM86-E02015 -08003-33.23-axis Goniometer Module with SMART APEX DetectorThe 3-axis goniometer module and itsassociated SMART APEX detector comprise the unique hardware of the SMART APEX system. This is the part of the instrument that actually performs the experiment.Several components comprise the 3-axis goniometer module with SMART APEX detector (Figure 3-2).•Goniometer with fixed chi (χ)stage •X-ray source (including shielded X-ray tube, X-ray safety shutter, and graphite crystal monochromator)•SMART rotary shutter and incident beam collimator (with beam stop)•SMART APEX detector •K760 X-ray generator •Manual control module •Video cameraGoniometer with fixed chi stageThe standard SMART APEX system uses a horizontally oriented D8 PLATFORMgoniometer base (with 2-theta [2θ] and omega [ω] drives) with dovetail tracks for the X-ray source and the detector, and mounting posts for accessories such as the video camera and optional low-temperature attachment. The system also incorporates a fixed chi stageFigure 3-2. SMART APEX & goniometer module instrumentationHardware Overview SMART APEX User ’s Manual3-4M86-E02015 -0800with chi angle of approximately 54.74° and a phi drive with 360° rotation.All four axes (2θ, ω, φ, and χ) intersect within a volume of approximately 10 microns. These axes are shown in Figure 3-3.Figure 3-3. Fixed χ, 3-axis goniometerX-ray sourceThree components (Figure 3-2) comprise the X-ray source: a shielded X-ray tube, an X-ray safety shutter, and a graphite crystal monochromator.The sealed tube X-ray source, with amolybdenum (Mo) target, produces the X-ray beam used by the SMART APEX system.The X-ray safety shutter is built into the X-ray tube shield. The shutter opens upon initiation of a set of exposures and closes upon the end of collection. Status lamps on the shutter housing indicate when the shutter is open (green) and closed (red). The shutter is also interfaced to the controller and to the safety interlocks.A tunable graphite crystal monochromator selects only the K α line (λ=0.71073Å) emitted from the Mo X-ray source and passes it down the collimator system.SMART Rotary Shutter and Collimator The monochromatic X-ray beam then passes through the labyrinth, the SMART rotary shutter, and the incident beam collimator before striking the specimen.•The labyrinth is a spring-loaded device,which ensures that the collimator and the SMART shutter are tightly connected to prevent X-ray leakage.•The SMART shutter is a device which precisely controls the exposure time foreach frame during data collection. ItsSMART APEX User ’s Manual Hardware OverviewM86-E02015 -08003-5status lamps indicate when the shutter is open (ON) and closed (OFF). This assembly also houses an automatic attenuator.•The incident collimator is equipped with pinholes at both front (near crystal) and rear (near source). These pinholes help to define the size and shape of the incident X-ray beam that strikes the specimen. You will normally use a collimator with 0.5 mm pinholes. (Collimators are available in a variety of sizes, depending on your application.)•The beam stop (a hook-like assembly attached to the collimator) catches the remainder of the direct beam after it has passed the specimen. The beam stop has been aligned to minimize scattered X-rays and to prevent the direct beam from hitting the detector.The entire collimator assembly is supported by a collimator support assembly, which has been precisely aligned to guarantee that the X-ray beam passes through the center of the goniometer.SMART APEX detectorThe SMART APEX detector is specific to this system. It is mounted on a 2θ dovetail track.The track has a scale that is calibrated to indicate the distance from the crystal to the phosphor window (a typical distance is 6 cm).Status lamps on the detector housing indicate when the detector is on (green) and off (red).K760 X-ray generatorThe K760 X-ray generator is a high-frequency, solid-state X-ray generator, which provides a stable source of power for operations up to 60 kilovolts (kV) and 50milliamps (mA). For the SMART APEXsystem, power settings should never exceed the maximum power rating of the X-ray tube.(Typical maximum power settings for the SMART APEX system with a normal focus tube are 50 kV, 40 mA. The kV setting should not exceed 50 kV.) This generator isinterfaced to the controller, and the power settings may be adjusted either from front panel buttons or from within the SMART software.Manual control moduleThe manual control module is a remotedevice that you will use in certain operations to manually drive angles (particularly inoptical alignment of a specimen). The module is physically the same as in other D8 systems but has a different keypad and functions. In this application, you will use only the first three rows of buttons and the AXIS PRINT button.Video cameraThe video camera, an essential part of the system, allows you to visualize the crystal to optically align it in the X-ray beam and to measure the crystal dimensions and index crystal faces. The camera is interfaced to the computer and is operated through the VIDEO program. The camera is mounted in the accessories track of the goniometer base.Hardware Overview SMART APEX User’s Manual3.3 AccessoriesVarious devices can be mounted in anaccessories track on the goniometer base.These include an optional low-temperatureattachment.3-6M86-E02015 -0800We are now ready to begin actual operation of the instrument, using the YLID test crystal (mentioned in section 1).

Carefully remove from its case thegoniometer head containing the YLID testcrystal.12. Place the goniometer head onto its baseon the phi (φ) drive, aligning the head’skey slot with the key (pin) in the base.Snugly screw the head’s collar to the base such that the head does not move, but do not overtighten it.Note: At φ=0°, the key on the mountingbase of the goniometer head will be at the 12:00 position.13. Click Crystal > Generator to check the X-ray power. The Goniometer /GeneratorOptions panel appears (Figure 4-18).Figure 4-18. Goniometer /Generator Options panel14. Set appropriate values for kilovolts (kV)and milliamps (mA). For this experiment,we want 50 kV and 30 mA. Click OK toprogram these new settings.4.3 Optically Align the SampleTo obtain accurate unit cell dimensions and to collect good quality data, you must align the center of the sample with the center of the X-ray beam and maintain the alignment for the entire experiment. We assume that your video camera has been aligned so that the crosshairs of the video camera coincide with the center of the goniometer and the center ofthe X-ray beam.M86-E02015 -08004-74-8M86-E02015 -0800Align the sample as follows:1. Click Crystal > Evaluate to begin thealignment of the sample in the center of the X-ray beam.The alignment process combines optical alignment steps with rotational photo steps. The menu bar at the top of the SMART screen remains gray (Figure 4-19) until you complete the opticalalignment step and exit by pressing the ESC key.Figure 4-19. Grayed SMART screen menu bar during optical alignmentDuring the first stage (optical alignment),you will control the instrument from the manual control module (Figure 4-20)using buttons A and B.Figure 4-20. Manual control moduleAlso during optical alignment, you will adjust the goniometer head at screw locations shown in Figure 4-21. Use the goniometer wrench to unlock the axis adjustment locks and later lock them. Use the other end of thewrench to turn the adjustment screws.M86-E02015 -08004-9Figure 4-21. Goniometer head adjustment locations2. Click on the Video window to display thereal-time image of the crystal (Figure 4-22).Figure 4-22. Real-time image of the crystal3. Press the A button on the manual controlmodule to drive the goniometer angles to the base position (2θ = -30°, ω = -30°)and φ = 0° for optical alignment.Note : If you have difficulty seeing the image of the crystal, you may want to better illuminate the sample with a high-intensity lamp and/or temporarily place a light-colored piece of paper on the front of the detector.4. Adjust the goniometer head ’s Z-axisadjustment screw (recall Figure 4-21) until the crystal is near the crosshairsintersection on the video screen (Figure 4-23).Figure 4-23. Crystal near the crosshairs intersection4-10M86-E02015 -08005. Adjust the goniometer head ’s X-axisadjustment screw to center the crystal on the crosshairs intersection (Figure 4-24).Figure 4-24. Crystal centered on crosshairs (φ =0°)6. Press the A button again to rotate the phiby 180° and to verify that you have correctly centered the sample at both φ=0° and φ =180°. (Do not be concerned if the crystal moves away from its center as it rotates; you have not yet adjusted the Y axis.)Note : Repeat this process as many times as necessary. Each time you press the A button, the phi angle will rotate between 0° and 180°.7. Press the B button to rotate the phi angleto 90° for adjustment of the Y axis (Fig 4-25).Figure 4-25. Crystal oriented for Y-axis adjustment8. Adjust the goniometer head ’s Y-axisadjustment screw (Figure 4-19) to center the crystal on the crosshairs intersection (Figure 4-26).Figure 4-26. Crystal centered on crosshairs (φ =90°)M86-E02015 -08004-119. Press the B button again to rotate the phiangle to 270° and to verify that you have correctly centered the sample at both φ=90° and φ =270°.Note : Repeat this process as many times as necessary. Each time you press the B button, the phi angle will rotate between 90° and 270°.The center-of-mass of a properly aligned specimen should stay in the same place with respect to the center of the crosshairs in all angle settings.Note : If the video camera has become misaligned, the center of the crosshairs may need to be adjusted by your system manager.10. Cycle between the two positions of both Aand B one last time to ensure that the crystal remains centered in all positions.11. After the alignment has been completedusing A and B positions, you should verify the alignment by using the C and D buttons in a similar manner.12. When you have completed the opticalalignment steps, remove any paper you might have placed on the detector face and close the doors of the enclosure.13. Click on the SMART program window,then press the ESC key to exit the optical alignment stage. SMART then prompts for a rotation photograph (Figure 4-27).Figure 4-27. Prompt for a rotation photograph14. Press Y (normal response). SMART willthen perform a 60-second rotation photo.During this time, phi data on the screen will be highlighted and the shutter data will read: OPEN. Upon completion of the photo, the image frame will display on the screen (Figure 4-28).Figure 4-28. Image frame following 60-second rotationAt this time, proceed to Unit CellDetermination.4.4 Unit Cell Determination Perform a unit cell determination as follows: 1. From the SMART program, click Crystal> Unit Cell. The following messageappears, asking you to verify that thedistance and beam center are correct(Figure 4-29).Figure 4-29. Distance and beam center verification2. Ensure that the distance shown on thedetector scale agrees with the valueshown on the screen. Then press Yes.SMART then displays a set of defaultvalues for unit-cell determination andasks you to confirm them (Figure 4-30). Figure 4-30. Set of default values for unit-cell determination 3. Press OK (as these values areappropriate for this crystal). The program then collects three sets of 20 framescalled MATRIX0, MATRIX1, andMATRIX2 (Figure 4-31).Figure 4-31. Frame collection (MATRIX0, MATRIX1, and MATRIX2)When all frames have been collected,SMART performs the steps ofthresholding, indexing, Bravais latticedetermination, and least-squaresrefinement of cell constants. The YLIDtest crystal has an orthorhombic primitiveunit cell, as shown in Figure 4-32.4-12M86-E02015 -0800。

2.自动语音：你做的所有事情都有一句角色语音，能替代你自己说话，比如你在停下来打血包，你的队友会听到自动语音说“我在打医疗包，请等一下”，当你搜东西不自觉跑远时，玩家的角色会语音告诉你“离开队友太远了”。
官方花了相当长的时间去专门改进陌生玩家信息交流的方式。
相信这个游戏的交流系统今后会成为多人游戏的标杆。
※丰富的角色职业系统和非常深的细节打磨角色职业系统则是这个游戏能长期运营下去的核心，也是和当前大逃杀类似游戏区别最大的地方。
单是这个设定就让它能比其他大逃杀游戏运营得更加灵活和长久，可以看产出EA和Respawn在这款游戏上非常有野心。
笔者目前还没体验过全部角色，暂时还不好说职业设计如何，目前职业设定粗略看起来有多种类型，因为限定3人组队，所以实际上没办法一次凑齐所有类型。
你可以组传统输出铁三角，也可以根据需要选择打野（侦查）等其他类型职业。
比起OW对职业的严格限制，《Apex英雄》则始终牢记自己是个射击游戏，无论什么职业，都可以依靠身法、枪法和战术来获胜，技能只能帮助玩家实现战术。

Printed in the USA. This manual was originally written in English. Hologic, APEX™, and associated logos are trademarks and/or registered trademarks ofHologic, Inc., and/or its subsidiaries in the United States and/or other countries. All other trademarks, registered trademarks, and product names are the property of their respective owners.This product may be protected by one or more U.S. or foreign patents as identified at /patents.1.0OverviewHologic, Inc. develops and markets a full line of Bone products including the APEX™ system. Ensuring the integrity of our systems is a top priority for Hologic. This document provides a guide for user “best practices” to ensure the integrity of Hologic products through their lifecycle. Additionally, this document outlines the most common cybersecurity vulnerabilities and the appropriate methods for securing our products. Hologic uses Microsoft Windows 7 and Windows 10 operating systems in its Hologic DXA medical products. Although Hologic performs extensive testing prior to the deployment of our computer systems, ongoing computer security threats may pose a significant threat to the security of these systems on a daily basis. These Cybersecurity Best Practice recommendations have been performed in a laboratory environment and have undergone extensive testing. Adherence to these security recommendations will minimize the risk of cybersecurity threats. An experienced IT professional should be able to follow these instructions with minimal difficulty.2.0IntroductionHologic continually monitors the current state of computer and network security to assess potential threats to our systems. Once the concern has been identified and properly classified, Hologic performs a risk analysis to determine the potential consequences of cyber attacks. Additionally, the risk analysis will assess the potential consequences for actively mitigating the threat by inducing a product change.Hologic also has an on-going maintenance program for the entire life cycle of our products. The on-going maintenance program consists of:•Periodic Vulnerability Assessments•Laboratory evaluation of Anti-virus products•Critical security updates validation•Creation of a Cybersecurity teamHologic is committed to delivering and maintaining our products in the rapidly changing environment of cybersecurity threats. By following the Cybersecurity Best Practices below and incorporating them into your facilities security policies and protocols, your cybersecurity risk and vulnerabilities will be minimized.2.1.AudienceThis document contains information related to the Hologic DXA system. It is intended to aid in securing the customer’s network infrastructure and network environment that incorporates Hologic products.The reader of this document should be familiar with the OSI model, networking, and network security.2.2.RemarksIt is recommended that the customer implement and maintain a set of facility security policies and procedures. These security policies and procedures should address the following:•Discretionary access control•Methods of auditing•Disaster Recovery Plans / Business Continuity Plans•Password reset policy•Perimeter security (e.g., firewalls, IDS, proxy servers)•Internal security (e.g., network topology monitors, log file review, weekly vulnerability scans)•Physical Security (e.g., biometrics, locks, cameras)•Security AwarenessIt is the customer’s responsibility to ensure the confidentiality, integrity and availability of the information technology resources in its organization.2.3.Definitions, Terms and Abbreviations802.1q: The IEEE standard for VLAN taggingACL: Access control listCBAC: Content Based Access ControlCLOC: Cyber level of concernDAC: Discretionary Access ControlDHCP: Dynamic Host Configuration ProtocolDMZ: Demilitarized zoneEgress: Traffic destined outboundFTP: File Transfer ProtocolIP: Internet ProtocolISL: Inter-switch link protocolLAN: Local Area NetworkLayer 3: Any device that utilizes the 3rd layer of the OSI model (AppleTalk, IP, etc.)IDS: Intrusion Detection SystemOSI model: Open Systems Interconnection Reference ModelVLAN: Virtual LANTCP/IP: Transmission Control Protocol/Internet Protocol suiteTFTP: Trivial File Transfer Protocol2.4.References•FDA Guidance for Off-The-Shelf Software Use in Medical Devices, 2016•FDA General Principles of Software Validation ; Final Guidance for Industry and FDA Staff, 2002 •NEMA Patching Off-the-Shelf Software Used in Medical Information Systems, 20043.0Network Security3.1.Active DirectoryHologic APEX systems are compatible with Active Directory however connecting them to network domains may cause undesirable behavior because of transfer of domain policies and other configurations to Hologic systems Since domain controllers override Hologic APEX system’s factory settings, Hologic cannot support issues caused by domain policies and recommends you remove the system from network domain should unexpected behavior occur.3.2.SegmentationProperly segmenting Hologic’s products from the rest of your network can further increase the security of the systems. The goal with segmentation is to prevent unauthorized access to the system(s) by utilizing ACLs. 3.3.1 VLANsVLANs (or Virtual LAN) are a way to create several different broadcast domains on a single switch. VLAN capability is available on most modern switches.Utilizing VLANs allows you to apply some level of security (access control lists and CBAC) to protect certain extensions of your network. If implemented correctly, this creates a “virtual” DMZ.Resources needed:•VLAN capable switch•Layer 3 switch OR existing router capable of recognizing different VLAN tagging (i.e.: 802.1q, ISL) •Knowledge of networking and Cisco productsNote: VLANs were designed for management purposes and not for security. There are specific cybersecurity threats (attacks) where a user can “jump” VLANs. A more effective way of segmenting a LAN would be using a physical interface off of a firewall.3.3.2 Firewall segmentationMany hardware firewalls are equipped with a 3rd interface. This interface is typically used as a DMZ in small to mid-size network. However, this 3rd interface may also be utilized to create a dwelling for machines that need increased security.3.3.Egress FilteringIt is recommended that you employ egress filtering on your network. This will reduce the chances of external data theft and/or loss. In the beginning stages of a system compromise, one of the first things an attacker will do is TFTP or FTP to a remote server that stores privilege escalation tools. Implementing proper egress filtering will reduce the chances of this occurring.work MonitoringEffective monitoring of your network may detect the initial reconnaissance stages of a potential attack. This is vital information to capture, as it may indicate how and when a system may be compromised. Network monitoring can be accomplished by utilizing an Intrusion Detection System (IDS).3.5.Remote AdministrationHologic does not allow the installation of remote monitoring programs like LogMeIn or VNC on the Hologic DXA System. Any administration that needs to be accomplished should be done physically at the PC or using Hologic Connect™. Alternatively, you can contact your local service representative for assistance.4.0Host Based Security4.1.Anti-virus ProductsIt is recommended that you employ anti-virus software to protect your APEX™ system. While there are several “All in one” anti-virus products available on the market, Hologic does not recommend using these as they may compromise system stability. These “All in one” anti-virus products usually include: an Antivirus engine, Anti-spy ware and stateful firewall. These can significantly raise CPU usage and memory usage during regular usage, which may result in:•CPU Deprivation•System hangs•Performance degradation•Potential data corruptionHologic recommends that anti-virus products be configured for "on-demand" scanning and not "real-time protection." Real-time protection can significantly raise CPU usage and memory usage which may result in problems during image acquisition.In the event that real time protection or auto scans can’t be disabled, it is recommended to create exceptions for Hologic specific folders to exclude them from anti-virus scans.4.2.Host-based FirewallsHologic does not allow the installation of 3rd party host based firewalls on our systems. Some 3rd party host-based firewalls are vulnerable to denial of service attacks and if improperly configured, may let an intruder gain system level access to the system. The APEX™ system comes shipped with Windows built in firewall enabled.4.3.System-level AuditingHologic’s products are shipped with auditing enabled to track security events. This is to provide accountability and to help diagnose potential problems that may arise. Please do not attempt to disable auditing. It is recommended daily review of the logs be completed to ensure the integrity of the system.4.4.Internet UsagePlease do not allow any users or staff to access the Internet from any of the Hologic DXA systems. This exposes your systems to a plethora of vulnerabilities such as:•Viruses•Spyware•Trojans•Hostile code (embedded into webpages)Hologic's products are considered medical devices; therefore you are not permitted to installunauthorized software on your own. Peer to peer software can expose your entire hard drive to any individual running the same type of software.4.5.AuditingHologic depend upon auditing to provide for accountability and to track system changes. It also assists us with diagnosing potential problems that may arise. Hologic has tested the Hologic DXA system with auditing enabled and determined that proper operation is not compromised.To enable auditing:1.Click START > run, and type gpedit.msc.2.Browse to Computer Configuration > Windows® Settings > Security Settings > Local Policy >AuditPolicy.3.Define every object for both “Success” and “Failure.”4.Browse to Control Panel > Administrative Tools > Event Viewer.5.Right click on “Security” and select properties.Browse to Control panel > Administrative Tools. Double click “Event Viewer.” Expand “Event viewer (Local)” > “Windows Logs” in the tree in left pane. Right click “Security” and select properties. Ensure that auditing is set to overwrite as needed. Maximum log size should not be smaller than 1000Kb. Failure to ensure this setting is enabled may prevent access to the machine should the hard drive become full.NOTE: It is important the clock on your system is set correctly. If the time is set incorrectly, it will not provide proper accountability in the event of a system compromise. Hologic recommends using an in-house NTP server to synchronize the clock on all your systems (including all network based monitoring devices)4.6.System PatchingHologic’s products are considered medical devices, therefore you are not permitted to upgrade the operating system or apply service packs that have not been validated by Hologic. Hologic periodically performs regression testing on critical patches and service packs.5.0Physical SecurityIt is recommended you employ some method of physical security when dealing with our systems. This ensures only authorized personnel have access to Hologic’s products.There are several vulnerabilities a malicious user could exploit locally. Some examples are: •Theft of equipment•Local password cracking•Installation of hardware keyloggers5.1.Desktop SecurityIt is of vital importance to ensure desktop security is addressed in your environment. Some examples of desktop security are:•Log out of system when not in use•Utilize a form of close captioned monitoring•Physically segment the systems in a secure room5.2.Onsite VendorsIf your organization uses vendors to assist in the administration of your network infrastructure, please make them aware of the recently added Hologic products. Ensure they do not make any configuration changes in any network devices. Doing so may adversely affect the performance of our products. It is also advised that you do not permit any outside vendors near our systems unless there is an absolute need (i.e., faulty network drop).6.0Securing Windows®6.1.CPU HibernationAPEX systems are configured from factory to never hibernate. This eliminates the possibility of scan being interrupted due to unexpected sleep timeouts.6.2.Null SessionsNull sessions are a built-in part of Microsoft’s operating system. They allow systems and users to view available resources from other servers or domains. This can be useful if you manage a large enterprise. However, there are severe risks with null sessions. Null sessions do not require authentication and leave no trace if the proper auditing isn’t in place. Windows is protected against null sessions by default. However, improper configuration can resurrect this vulnerability. To ensure your machine is protected against Null Sessions, perform the following:1.Open up Administrative tools (via control panel).2.Double click Local Security Policies.3.Expand Local Security Policies and highlight “Security Options.”4.Locate the parameter titled “Network Access: Do Not Allow Anonymous Enumeration of Samaccounts.”5. Ensure this is set to “Enabled.”6. Perform the same for “Network Access: Do Not Allow Anonymous Enumeration of Sam accounts andshares.”Additionally, disabling NetBIOS over TCP/IP and Unbinding File and Print Sharing will remove all SMB based protocols in the Hologic DXA system. This will effectively thwart all SMB based password attacks.6.3.Disabling ServicesBrowse to Control Panel>Administrative Tools>ServicesLocate the following services. Set the services to a “stopped” and “disabled” state.•Remote Registry6.4.Password SecurityIn today’s world, passwords can be compromised in literally seconds by using a wide variety of tools and techniques. As new automated tools are invented each year, the more trivial it becomes to crack passwords (both remotely and locally). To lower the possibility of a compromised password, it is vital that a set of protocols be adhered to.•Choose a password between 7-10 characters (choosing a password 15 characters or greater ensures the password is not stored as LmHash).•Use special characters in the password (i.e., @ % & ).•Do not share your password.•Do not base your password on a pet, loved one or dictionary name.•Do not write down your password.•Make your password alphanumeric. This can trick a potential attacker (some tools only crack passwords upper-case).•Examine the back of your host computer system for hardware keyloggers.•Do not leave your account logged in.•Routinely examine the event viewer logs. Under the “Security” tab, look for failed attempts. This may be a sign of an attack.•Define an “Account lockout policy” (see below).Furthermore, your Hologic DXA system is configured so any local passwords are not stored as LANMAN. This will thwart most locally based password attacks.6.5.Account Lockout PolicyDefining an “Account Lockout Policy” ensures a user account will be locked out after a pre-defined amount of failed attempts. This is important to define, as it will protect your user account from being “brute forced attacked.”7.0Further AssistanceHologic is here to help.

Our full line of products can provide the accessories that match your life style; no matter what type of RV you own. Check with your dealer to discover the products that can make your life more Carefree.The Apex Patio Awning offers the coach owner an awning system that provides as much or as little shade as required. The versatile awning system is available as a single awning or as a 2 or 4 awning combination with all awnings controlled at a single master control pad.Each unit is equipped with Apex lateral support arms that are the strongest available on the market. No vertical arms interfere with coach sidewalls or equipment that may be mounted on the roof. These arms can also be adjusted to vary the canopy pitch up to 2 feet (it is strongly recommended that service and adjustments be performed by trained technicians).The canopy is made from Sunbrella® acrylic fabric. The canopies are housed in an aluminum case that easily blends in with the coach roof.The unique and innovative 110V electronic control system provides Carefree’s Direct Response system with interior pushbutton controls for standard extend/retract functions. At the master control panel the auto-retract system can be engaged to automatically retract the awning in windy conditions. Sensitivity can be set to respond to a variety of wind speed conditions. An RF remote is included with the Direct Response system.O PERATIONThe Direct Response system provides a wide range of awning controls with control panel operation in one convenient location. The standard operation is straight-forward with the buttons clearly labeled. The control panel is designed to allow the user to control each awning individually or together. Each function is described below. These buttons operate the same with or without the auto-retract system turned on.Operational Notes:Ignition Lockout Sensors:If the optional Carefree EL ignition lockout is installed the system will disable the extend function while the vehicle ignition key is in the ON position.Special order RTL ignition lockouts will fully retract the awning and disable the extend function when the vehicle ignition key is in the ON position.Functions will return to normal operation when the ignition key is turned OFF.Coach manufacturers may install their own lockout design. Refer to the coach literature for AC power for accessories.Awning MotorThe awning motor is equipped with a thermal protection circuit to protect the motor from overheating. Operating the awning repeatedly over a short time period may cause the circuit to sense a overheat condition and shut off the motor. If this occurs, wait approximately 15 minutes to allow the motor to cool then operate the awning in normal fashion.23Extend Press and release. The awning will extend out to the full extensionand stop automatically. When the button is pushed, the LED willilluminate and stay on until another function is activated.During normal operation, the awning will extend out completely thenroll back slightly to provide tension to the fabric.NOTE: If the optional ignition lockout safety is installed, the systemdisables the extend function while the vehicle ignition is in the ON position.Stop Press and release. During extend and retract functions, the operator maystop the awning by pressing this button. When the button is pushed, theLED will illuminate and stay on until another function is activated.RetractPress and release. The awning will retract and stop automaticallywhen the awning is fully retracted. When the button is pushed, theLED will illuminate and stay on until another function is activated. The function LEDs (extend, retract and stop) perform a dual function. When the buttonis pressed, the LED illuminates. The LED stays illuminated during the selectedoperation and after the awning has fully extended or retracted. This provides anindicator of the awning position. When the stop button is pressed, the LED willilluminate and stay on until a function is pressed. If on, it indicates that the awning ispartially extended/retracted.NOTE: When 110VAC power is removed from the system, the controller doesnot retain previous positioning information. When power is restored, positioninginformation is updated when the first function is initiated.CAUTION At startup (110VAC applied) DO NOT press the retract buttonto update the positioning information. This can cause the motor to run in an overcurrent mode. If this occurs, the motor’s thermal protection device may shut offthe motor and the operator must wait approximately 15 minutes, for the motor tocool off, before operating the awning. To properly set the positioning, push theextend button, allow to run for 1 second then press the stop or retract button.Carefree of Colorado 4T HE A UTO -R ETRACT S YSTEMwill be on when the system is active.The Direct Response setting for your preferences.seconds or longer, the system will automaticallyretracts the awning.

Just follow these basic steps:∙ Always operate the awning according to the instructions.∙ Periodically check that the fasteners are tight. Tighten if necessary.∙ Keep the awning fabric and arms clean.F ABRIC C ARED O NOT USE OIL BASED CLEANERS OR ANY CAUSTIC , GRANULATED , OR ABRASIVE TYPECLEANERS ON YOUR C AREFREE PRODUCT .1. One of the best ways to keep the fabric looking good and to delay the needfor deep or vigorous cleanings is to hose fabrics off on a monthly basis withclear water. This practice will help prevent dirt from becoming deeplyimbedded in the fabric. In most environments, a thorough cleaning will beneeded every two to three years.2. When it’s time for a thorough cleaning, the fabric can be cleaned while stillon the awning frame.∙ For Acrylic Fabric – Use a stiff brush and warm water with soap.3. When cleaning the fabric, it is important to observe the following:∙ Always use a natural soap, never detergent.∙ Water should be cold to lukewarm, never more than 100︒F.∙ Air-dry only. Never apply heat to the fabric.∙ Always allow the fabric to dry thoroughly before rolling up the awning.M ILDEWMildew is a fungus growth that looks like dirt. Under ordinary conditions, mildewwill not appear. However, in areas where high temperature and humidity arecommon, mildew can be a problem and required the material to be washed morefrequently. Thoroughly rinse the fabric with clean water and allow to air drycompletely before rolling up the awning.P OOLINGWhen water collects on the top of the fabric, this is known as "pooling". This can occurduring inclement weather or if a running air conditioner discharges over the awning.The water is dumped when the awning is retracted. It is recommended that if wateraccumulates on the top; retract the awning in steps (8"-12") to dump the water. This willhelp prevent the fabric from stretching or distorting.A RM C AREThe best method of keeping the arms and braces operating smoothly is to cleanthem.Periodically wash the spring arms with running water (i.e. a hose) to keep themclean. Lightly spray the arm joints with a dry silicone lubricant, after the armshave been cleaned and dried thoroughly.APEX NOTES:9Carefree of Colorado NOTES:10APEX C AREFREE M AJOR P RODUCT L IMITED W ARRANTYCarefree of Colorado (hereafter referred to as Carefree) warrants to the first retailPurchaser that the Carefree Product is free of defects in material andworkmanship within the terms and conditions as set forth in the warrantystatement available online at .

Respawnwas founded in 2010 by two of the original creatorsof the successful and influential Call of Duty series. The studio’s first game was Titanfall, released in 2014. It also released a sequel, Titanfall 2, in 2016. Both Titanfall games were first-person shooters with com-petitive online modes. As they battled, players could run up walls, zip across maps using grappling hooks, and even pilot huge robots called Titans. These abili-ties helped create a fast-paced style of movement that set the Titanfall games apart from the competition.Both Titanfall games sold well and were much-loved by critics and players alike. However, they were not massive hits. After the release of Titanfall 2, the team at Respawn started thinking of ways to make a third entry in the series stand out. One idea they tried was to combine the basic controls and feel of Titanfall with the battle royale game structure that was becom-ing popular at the time. After changing a few things from the Titanfall games, such as removing the giant robots, they found that the combination worked very well. However, they also realized that the project theyAPEX LEGENDS: Beginner’s Guide9UNOFFICIALGlossarydevelopersgames or other computer programsinfluentialbecome popular in the futuremicrotransactionscan be purchased for a small amount of money within a videogame or other computer programmodpassiverequiring a player to do anythingrespawnbeing defeatedskinsweapons can take on intactical30Find Out More BOOKSCunningham, Kevin.Michigan: Cherry Lake Publishing, 2016.Powell, Marie.

《Apexlegends》游戏简论(一)
《Apex legends》游戏简论（一）《Apex legends》是一款由EA公司旗下Respawn Entertainment工作室研发的第一人称大逃杀游戏，它沿用了《泰坦》（Titanfall）世界观设定,背景设定在《泰坦陨落2》的30年以后。
2019年2月5日，在PS4，Xbox One，PC平台上线，根据开发商CEO Vince Zampella在Twitter上公布的数据在上线8小时在线用户数量就突破100万之后。
此后Respawn Entertainment首席执行官在博文中宣布Apex legends游戏上线72小时在线游戏玩家数量突破1000万。
截止2月11日，《Apex Legends》累积玩家数量超2500万，同时在线人数超200万。
这款游戏超过《英雄联盟》和《堡垒之夜》成为了2月份国外游戏直播平台Twitch上观看人数第一的游戏。
与PUBG，《堡垒之夜》和《使命召唤15·黑色行动》等大逃杀游戏类似，《Apex》的游戏模式是：玩家以三人组队模式，加入一场60位玩家上限的游戏房间，最后存活的一个小队获胜。
进入游戏后，地图上方随机刷新一条航线，玩家乘飞机进入地图，选择合适的时机跃出飞机，滑行并降落至自选地点，搜集物资。
游戏将在一定时间后逐步缩小可供玩家活动的安全区，直至决出获胜者。
相对于其他的大逃杀游戏，该游戏有几点较大的区别：1.玩家被淘汰后，队友仍有机会将其召回战场；2.取消了载具，改为滑索，滑翔气球；3.防具的耐久消失不再会导致防具损坏，通过充能可以回复防具的防护能力；4.玩家可选择的不同角色特点更为鲜明，Moba元素更浓；5.独特的Champion机制，上局游戏的获胜者或是当局游戏的击杀王会被游戏内的海报展示出来。
游戏的收费方式：《Apex legends》与《堡垒之夜》类似采用游戏本体免费，DLC和开箱收费的方式进行盈利，第一年的季票内容官方已经放出来计划。
开始使用Apex之Apex简介
开始使⽤Apex之Apex简介对于那些对新⼀代业务应⽤程序感兴趣的开发者⽽⾔，Apex代码是第⼀个多租户（multitenant）、按需（on-demand）编程的语⾔。
开发者在⽤户界⾯可以使⽤很多订制选项，如定义新的字段，对象，⼯作流程，批准流程；除此之外，从客户端程序还可以通过SOAP API来发起诸如delete(),upsert()之类的数据操作请求。
什么是Apex?Apex是⼀种强类型（strongly typed）的⾯向对象编程语⾔（object-oriented programming language），开发者可以通过调⽤ 中的API接⼝在服务器上操作流程，管理事务控制等。
Apex的语法规则与Java类似，但是其⾏为表现的与数据库的存储过程类似；Apex允许开发者在系统事件中添加业务逻辑，包括按钮点击、相关记录更新，VisualForce页⾯；Apex代码可以由Web服务请求和对象触发器发起。
作为⼀种开发语⾔，Apex具有以下特点：Apex是整合的（Integrated）Apex为通⽤的平台的编程提供了内在⽀持，包括：1.数据操作语⾔（Data Manipulation Language，DML）的使⽤，如INSERT、UPDATE、DELETE，并且提供了处理异常的接⼝DmlException；2.内联的salesforce对象查询语⾔（Salesforce Object Query Language，SOQL）和salesforce对象搜索语⾔（Salesforce Object Serach Language，SOSL），这两种语⾔⽤于返回sObjects对象集合；3.循环，⽤于⼀次批量处理多条数据4.锁定语法（Locking syntax），阻⽌记录更新冲突5.Custom public API calls that can be built from stored Apex methods6.当⽤户对正在被Apex引⽤的数据实⾏操作、删除时进⾏警告和报错提⽰；使⽤⽅便Apex是类Java语⾔，在变量、表达式、代码块、条件语句、循环语句、类、数组等的⽤法上有很多相似之处；所以使⽤过类似的语⾔，Apex是很容易上⼿的。

狼与狮子介绍英文作文
狼与狮子介绍英文作文Title: A Comparative Study of Wolves and Lions。
Introduction:Wolves and lions are both apex predators in their respective ecosystems, commanding respect and fascination from humans and other animals alike. Despite their shared position atop the food chain, these two species exhibit striking differences in behavior, social structure, hunting techniques, and ecological roles. In this essay, we will explore and compare the unique characteristics of wolvesand lions.Physical Characteristics:Wolves are known for their lean, muscular bodiesadapted for endurance and agility. They typically have shaggy fur in various shades of gray, brown, black, or white, with bushy tails and pointed ears. On the other hand,lions are robust and muscular, with tawny fur and a distinctive mane in males. Male lions are larger and more heavily built than females, while lionesses lack a mane and are more streamlined for hunting.Habitat and Distribution:Wolves are highly adaptable creatures found in diverse habitats ranging from forests and tundra to grasslands and deserts. They are distributed across North America, Europe, Asia, and even parts of Africa. In contrast, lions are primarily found in savannas, grasslands, and open woodlands of sub-Saharan Africa, with a small population persisting in the Gir Forest of India.Social Structure:One of the most significant differences between wolves and lions lies in their social structures. Wolves are highly social animals that live in packs, typically consisting of an alpha male and female, their offspring, and occasionally other subordinate members. The packstructure is essential for cooperative hunting, territory defense, and raising offspring. In contrast, lions form prides, which are family units consisting of related females, their offspring, and a coalition of one or more dominant males. Lions exhibit a more complex social hierarchy compared to wolves, with pride dynamicsinfluenced by factors such as dominance, kinship, and territoriality.Hunting Behavior:Wolves are skilled hunters that rely on teamwork and strategy to bring down prey. They use coordinated tactics such as chasing, encircling, and ambushing to target large herbivores like elk, deer, and bison. Wolves are also opportunistic scavengers, feeding on carrion when available. Lions, on the other hand, are renowned for their strength and power, often hunting in coordinated groups to take down large ungulates such as zebras, wildebeest, and buffalo. Unlike wolves, lions rely more on stealth and ambush tactics, with lionesses doing the majority of the hunting while males defend the pride's territory.Ecological Impact:Both wolves and lions play crucial roles in maintaining the balance of their respective ecosystems. As apex predators, they regulate prey populations, prevent overgrazing, and indirectly shape vegetation dynamics. The presence or absence of these predators can have cascading effects on the entire food web, influencing the abundance of other species and the overall health of the ecosystem.Conclusion:In conclusion, while wolves and lions share the status of apex predators, they differ significantly in their physical characteristics, habitat preferences, social structures, hunting behaviors, and ecological impacts. Understanding these differences not only enriches our knowledge of these fascinating animals but also highlights the importance of conserving their habitats and protecting their populations for the benefit of entire ecosystems.。

Apex的Trigger类简介
Apex的Trigger类简介Apex TriggersApex 触发器（Apex Triggers）是⼀种特殊的 Apex 类。
它的主要作⽤是在⼀条记录被插⼊、修改、删除之前或之后⾃动执⾏⼀系列的操作。
每⼀个 Trigger 类必须对应⼀种对象。
Trigger 的语法和普通的 Apex 类⼀样。
Salesforce 建议开发者在创建 Trigger 之前，考虑⼀下相同的操作可否通过 Salesforce 的设置界⾯中的功能完成，⽐如验证规则（Validation Rule）、⼯作流规则（Workflow Rule）等。
如果可以，则优先使⽤它们。
Trigger 结构与触发事件Trigger 的标准结构如下：trigger Trigger名字 on 对象名字 (触发事件) {// Do something}Trigger 类必须以关键字 “trigger” 开始，然后是此 Trigger 的名字。
接下来是 “on” 关键字，然后是 Trigger 对应的对象的名字。
对象名字后⾯的括号中写⼊触发 Trigger 的事件。
Trigger 的触发事件分为以下⼏种：before insert：插⼊数据之前before update：更新数据之前before delete：删除数据之前after insert：插⼊数据之后after update：更新数据之后after delete：删除数据之后after undelete：恢复数据之后⽐如：trigger HelloWorldTrigger on Account (before insert, before update) {System.debug('Hello World!');}这个 Trigger 在每⼀个 Account 对象插⼊或更新之前执⾏。
如果执⾏了如下代码：Account a = new Account(Name='test');insert a; = 'test2';update a;在这两个 DML 语句⽣效前，系统的⽇志中会添加 “Hello World!” 的记录。
