United States Healthcare Data Breaches: Insights for NIST SP 800-66 Revision 2 from a Review of the NIST SP 800-66 Revision 1

Healthcare security and privacy breaches are occurring in the United States (US), and increased substantially during the pandemic. This paper reviews the National Institute of Standards and Technology (NIST) publication base as an effective solution. The NIST Special Publication 800-66 Revision 1 was an essential standard in US healthcare, which was withdrawn in February 2024 and superseded by SP 800-66 Revision 2. This review investigates the academic papers concerning the application of the NIST SP 800-66 Revision 1 standard in the US healthcare literature. A systematic review method was used in this study to determine current knowledge gaps of the SP 800-66 Revision 1. Some limitations were employed in the search to enforce validity. A total of eleven articles were found eligible for the study. Consequently, this study suggests the necessity for additional academic papers pertaining to SP 800-66 Revision 2 in the US healthcare literature. In turn, it will enhance awareness of safeguarding electronic protected health information (ePHI), help to mitigate potential future risks, and eventually reduce breaches.

Preparation of Diamond-like Carbon Films on the Surface of Ti Alloy by Electro-deposition

In this paper, diamond-like carbon (DLC) films were deposited on Ti alloy by electro-deposition. DLC films were brown andcomposed of the compact grains whose diameter was about 400 nm. Examined by XPS, the main composition of the filmswas carbon. In the Raman spectrum, there were a broad peak at 1350 cm^(-1) and a broad peak at 1600 cm^(-1), which indicatedthat the films were DLC films.

Cathodic micro-arc electro-deposition of ZrO_2 coatings in an aqueous solution containing colloidal particles

By a novel technique-cathodic micro-arc electro-deposition (CMED), ZrO_2coatings were deposited on an FeCrAl alloy. Experimental results show that the necessary conditionsfor obtaining ZrO_2 coatings are to apply a pulse peak voltage over a critical value and addmoderate amounts of ZrO_2 colloidal particles and Zr(NO_3)_4 in the aqueous solution. Theas-deposited coatings are porous because hydrogen, water, and other vapors are generated andreleased from the coatings to the solution during the spark reaction. The coatings containmonoclinic and tetragonal crystalline ZrO_2 with certain degree of amorphous structure. Theprocessing parameters and mechanism of CMED were discussed.

Mechanical Characterization of Close Cell Aluminum Foams Reinforced by High Voltages Electro-deposition

The parameters for the electro-deposition of Cu were optimized in order to increase the compressive properties of close cell aluminum. Different values of deposition voltages and times were considered to vary the amount of deposited Cu. The surface morphology of the coating was observed by SEM and the compressive properties were evaluated by MTS. The results show that the coating is more homogeneous and compact with increasing voltage in a certain range, and beyond which, the coating quality decreases apparently. The reason is dedicated to the discharge rate of Cu2+ and nucleus formed in unit time. The compression results show three experienced stages: elastic deformation stage, collapse deformation stage and densification stage. After the electro-deposition of Cu, the elasticity modulus is increased obviously and the platform stress is also increased. Under the same strain, the stress of the aluminum foam with coating is reinforced comparing with the aluminum foam without coating. Furthermore, the platform area is widened apparently. In addition, Cu-SiC nanocomposite coatings are electrodeposited in alumium foams for further improving the mechanical characterization.

Electro-Deposition of Ni-La Film in Urea-NaBr Melt and Its Hydrogen Evolution Properties

The Ni-La alloy was electro-deposited in urea-NaBr melt. The codeposition behavior and effect of the cathodic current density on the coating composition were examined. As a result, lanthanum codeposited with nickel to form Ni-La alloy under the inducement effect of nickel. With the increase of the cathodic current density, the content of lanthanum of the deposit rose at first, then decreased, and reached the maximal value (10.3%(atom fraction)) at the current density 15 mA·cm-2. The crystallization behavior of Ni89.7La10.3 coating was investigated by means of differential scanning calorimetry and X-ray diffraction. The structure of Ni89.7La10.3 as-plated coating was amorphous phase. The amorphous phase was converted into center cubic close packed Ni-La (Fm3m) solid solution at 469.8 ℃. The electro-catalytic activity of hydrogen evolution of Ni89.7La10.3 coating was studied using electrochemical experiments, the results showed that the electro-catalytic activity of hydrogen evolution of Ni89.7La10.3 coating was better than that of nickel.

The role of time preferences in contract breach:Evidence from Chinese poultry farmers participating in contract farming

Farmers’contract breach behavior is cited as one of the major stumbling blocks in the sustainable expansion of contract farming in many developing countries.This paper examines farmers’contract breach decisions from the perspective of time preferences.The empirical analysis is based on a household survey and economic field experiments of poultry households participating in contract farming conducted in Jiangsu Province,China.A discounted utility model and a maximum likelihood technique are applied to estimate farmers’time preferences and the effect of time preferences on contract breach in the production and sales phases are explored with a bivariate probit model.The results show that,on average,the poultry farmers in the sample are generally present biased and impatient regarding future utility.The regression results show that farmers with a higher preference for the present and a higher discount rate are more likely to breach contracts,and time preferences play a greater role in the production phase than in the sales phase.When considering heterogeneity,specific investments and transaction costs promote contract stability only for farmers with a low degree of impatience.Moreover,compared with large-scale farmers,small-scale farmers’contract breach decisions are more significantly affected by their time preferences.These results have implications for contract stability policies and other issues that are impacted by the linking of behavioral preferences to agricultural decisions.

Electro-deposition tangsten coating on low activation steel substrates from Na_2WO_4-ZnO-WO_3 melt salt

Tungsten coating is considered as a promising alternative material for plasma facing materials(PFC) in future fusion devices.The electro-deposition of tungsten in Na_2WO_4-ZnO-WO_3 melt at 1173 K on low activation steel substrates was studied in this work.Adherent and smooth tungsten films were deposited under various pulsed current conditions.The crystal structure and microstructure of tungsten deposits were characterized by XRD,SEM and EDX techniques.The results show that pulsed current density and duty cycle have a significant influence on tungsten nucleation and electro-crystallization phenomena.Uniform and smooth tungsten coating with high purity and high adherence is obtained on low active steel substrates as cathodic current density ranges from 35 to 25 mA·cm_(-2).

Structure and Magnetic Properties of Ni Nanowires Array Fabricated by Direct Current Electro-deposition in Anodic Alumina Membrane

Ordered nanostructure arrays of Ni-Al 2O 3 were synthesized by direct current electro-deposition in anodic alumina membranes (AAM). The investigation with a n electron microscope,an X-ray diffractmeter and a vibration sample magnetomete r indicates that the Ni nanowires, growing in the pores of AAM with about 45nm i n diameter, are monocrystalline and have a definite preferred crystallizing orie ntation. The magnetic behavior of the arrays and their mechanism were discussed.

Effect of Pulse Parameters on Deposition in Concrete Crack using Pulse Current Electro-deposition

To evaluate the effect of pulse parameters on the formation of electrodeposits in concrete cracks, five different types of pulse current were set up, and ZnSO_4 and MgSO_4 solutions were used as the electrolytes. The rate of weight gain, rate of surface coating, rate of crack closure and crack filling depth were measured. Scanning electron microscopy was used to assess the morphology of the electrodeposits, and energy dispersive spectroscopy was used to analyze the mineral composition of the electrodeposits in the cracks. The experimental results demonstrate that, among five different pulse parameters, when T_（on）/T_（off）=0.8 ms/0.8 ms, the healing effect of electro-deposition is the best. The pulse mode hardly affects the mineral composition of the electrodeposits but changes the micromorphology. In addition, for both ZnSO_4 and MgSO_4 solutions, when T_（on）/T_（off）=0.8 ms/0.8 ms, the crystal structure of the electrodeposits is the most uniform and the densest.

Electro-Deposition of Cu on Open Cell Aluminum Foams

This manuscript deals with the electro-deposition of Cu on aluminum foams. Metallic foams are highly porous materials which present complex structure of three-dimensional open cells. This aspect causes strong limitations in mass transport due to electro-deposition technology. Experimental tests were performed to study the influence of the operational parameters on the overall performance of the coated aluminum foams. The experimental findings revealed that the manufactured metal foams were characterized by a high thermal conductivity and low process costs, making these materials very promising in many technological fields. On the basis of the experimental results, analytical models are proposed to predict the quantity and the quality characteristics of the coating.

Modeling of breaching parameters for debris flow dams

The debris flow dam is a common type of barrier dams,which shows significant differences from other types of barrier dam such as landslide dam,moraine dam in their formation processes,dam body shapes,and internal compositions.The basic breaching parameters such as flood peak discharge are vital indicators of risk assessment.In this study,we elucidated the failure process of the debris flow dam through the flume experiment,and built the calculation equation of the breaching parameters by selecting critical factors.The result shows that the overtopping failure process of the debris flow dam is capable of forming significantly retrogressive scarps,and the failure process experiences three stages,the formation of the retrogressive scarp,the erosion of the retrogressive scarp,and the decline of the retrogressive scarp.Five factors used for establishing the calculation equations for peak discharge(Qp),final width(Wb)of the breach,and duration(T)of the debris flow dam failure are dam height(h),reservoir capacity(V),the fine grain content(P0.075)of the soil,the nonuniformity coefficient(Cu)of the soil,and the upper limit grain size(D90)of the soil,respectively.In the three equations,the correlation coefficients between Qp,Wb,T and the five factors were 0.86,0.70,0.63,respectively.The equations still need to be modified and verified in actual cases.

Identification of the Breach of Short-Term Rental Regulations in Irish Rent Pressure Zones

The housing crisis in Ireland has rapidly grown in recent years. To make a more significant profit, many landlords are no longer renting out their houses under long-term tenancies but under short-term tenancies. Regulating rentals in Rent Pressure Zones with the highest and rising rents is becoming a tricky issue. In this paper, we develop a breach identifier to check short-term rentals located in Rent Pressure Zones with potential breaches only using publicly available data from Airbnb (an online marketplace focused on short-term home-stays) and Irish government websites. First, we use a Residual Neural Network to filter out outdoor landscape photos that negatively impact identifying whether an owner has multiple rentals in a Rent Pressure Zone. Second, a Siamese Neural Network is used to compare the similarity of indoor photos to determine if multiple rental posts correspond to the same residence. Next, we use the Haversine algorithm to locate short-term rentals within a circle centered on the coordinate of a permit. Short-term rentals with a permit will not be restricted. Finally, we improve the occupancy estimation model combined with sentiment analysis, which may provide higher accuracy.

Considerations for Restriction on the Right of Rescission in Case of Obviously Minor Breaches

Whether,and how,to rescind the right of one party(the non-breaching party)to rescind a contract in case of an obviously minor breach by the other party(the breaching party)is a recurring topic in the field of contract law.The Minutes of the Ninth Work Conference of the Courts Nationwide on Civil and Commercial Trial(the Minutes of the Ninth Work Conference)stipulates that whether a contract shall be rescinded depends on whether a breach is obviously minor and affects the fulfillment of the contract purposes expected by the non-breaching party.In juridical practice,however,there are no clear criteria to define what constitutes obviously minor breaches,and the factors considered in such cases are often inadequate to allow for a fully considered decision.By analyzing Article 55 of the Judicial Interpretation of the General Provisions of Contracts of the Civil Code of the People’s Republic of China(Draft for Comments)and reviewing the previous juridical practices,we present our conclusions regarding the conditions and factors that should be considered when restricting the right of rescission in cases of obviously minor breaches with a view to unifying the judicial judgment criteria by differentiating the type of breaches.

考虑超标准洪水作用的沥青心墙坝溃决生命损失评估模型

抗冲刷能力更强的沥青心墙坝一旦遭遇超标准洪水,将面临溃决风险,对下游人民造成严重威胁。现有针对沥青心墙坝的溃决生命损失研究尚属匮乏,亟需开展生命损失评估。本文分析超标准洪水作用下沥青心墙坝的溃决特征,考虑生命损失影响因素之间的相互作用过程,基于溃决洪水致灾机制构建生命损失定量评估模型,实现溃决生命损失的快速定量分析;通过方法对比和敏感性分析,明晰不同影响因素对溃决生命损失的作用规律。将模型应用于新疆射月沟溃决案例发现:溃决洪峰流量为3320 m^(3)/s,溃决历时3.35 h,与实际结果相符;生命损失定量模型分析结果为31人,与实际误差在11%以内,优于其他损失模型;风险人口的敏感性指数I_(max)和I_(min)值最大,分别为1.436、0.486,是射月沟溃决生命损失最重要的影响因素,其他依次为洪水严重性、是否撤离、警报时间、淹没范围。

非黏性堤防溃口发展过程计算模型

堤防是防洪工程体系的重要组成部分,一旦发生溃决将可能带来严重灾害损失,明确堤防溃口发展速率与水力要素之间的关系对于预测堤防溃决过程和洪水演进具有重要意义。通过对系列非黏性沙质堤防溃决试验结果进行整理分析,得到溃口垂向下切速率、横向展宽速率与溃口流量、溃口单宽流量之间的关系。结果表明:堤防溃口发展主要存在垂向冲刷、横向扩展2种形式;溃口发展速率与溃口流量呈正相关,但受入流流量影响,没有适用于所有工况的关系表达式;溃口发展速率与溃口单宽流量间的关系基本不受入流流量影响,下切和展宽速率与溃口单宽流量呈现指数关系;基于此关系,构建了以溃口单宽流量为参数的溃口发展过程计算模型,并对溃口垂向下切、横向展宽发展过程进行了模拟计算与对比分析,结果显示模拟情况与真实的溃口发展过程吻合较好,说明所提出的计算模型科学合理,且计算过程简洁。

我国背信犯罪的教义学阐释——以《刑法修正案(十二)》为起点

背信犯罪的目的型法益是财产,手段型法益是信任,其中“信任”法益居于从属地位。背信犯罪的主体是为他人处理事务者,这里的“事务”应具有财产性和“他人性”,“利他性”不等于“他人性”。非法经营同类营业罪的特征是“干自己的事,使单位受损”,因此不是背信犯罪。背信犯罪的事务应具有裁量性,不包括纯粹机械性劳务。德国将背信罪分为“滥用权限型”与“违背信任型”,将越权代理归入后者。然而,罪名的行为类型应是并列关系,而非包含关系,且滥用代理权与超越代理权在财产损失的认定上没有区别。背信犯罪的行为类型应划分为不当代理行为和非代理行为,前者涉及内部关系和外部关系,后者仅涉及内部关系。传统观点认为,一项罪名要么是针对个别财产的犯罪,要么是针对整体财产的犯罪,这种看法过于绝对。盗窃罪、诈骗罪及背信犯罪均存在针对个别财产的情形和针对整体财产的情形。在三方给付的场合认定整体财产损失,应以全部给付(担保人给付)时为时间标准。

考虑人体与水流相互作用的溃坝洪水生命损失评估模型

溃坝洪水会给下游人民群众造成巨大的生命损失,开展溃坝洪水造成的生命损失风险定量评估对应急抢险救灾具有重要的现实意义。本文在已有生命损失贝叶斯网络HURAM1.0模型基础上,引入了人体稳定性物理模型,考虑人体与水流相互作用关系,对处于洪水中的人先进行稳定性判定,并进行溺水判定,运用蒙特卡洛模拟方法,综合了水深和水流速对生命损失的影响,建立HURAM2.0模型;并将该模型应用于唐家山堰塞坝溃坝洪水生命损失分析。结果表明:HURAM2.0模型建立了水流流速对生命损失影响的定量关系,更精确地刻画了人体在水流中的稳定性和求生能力,相比HURAM1.0模型对较强洪水强度条件下的生命损失预测结果更准确。同时,在本文建立的模型中,除水深度、洪水严重程度变化不大,其余变量的敏感性均有所上升,其中居民区住宅层数、在建筑物中庇护情况和溃坝时长等变量对模型计算结果的最大影响程度分别增加142%、95%和93%,加强了模型在低、中、高3类洪水强度下的解释性,与HURAM1.0相比在贝叶斯反演分析中更占优势。在唐家山堰塞坝溃坝风险分析中,HURAM2.0能区分出不同水流速条件下的生命损失,更符合实际情况,即开挖泄流槽前风险大、死亡率高,在现场勘测和开挖泄流槽后风险及死亡人数大大降低,建议结合预警疏散以降低生命损失风险。

爬高型堰塞坝漫顶溃决机理研究

我国西南地区频发的地质构造活动和极端自然灾害诱发了大量的堰塞坝,属于堰塞坝的高发地,其形成的堰塞坝具有突然性强、危险性大的特点,严重威胁所在流域人民的生命财产安全,深入研究爬高型堰塞坝溃坝过程可为除险减灾提供科学理论支撑。为此,以土颗粒级配、背水面坡度、爬高型堰塞坝坝顶形状为影响堰塞坝漫顶溃决的主要因素,从漫顶溃决过程、溃口流量过程、溃口演变过程、溃后残留坝体及下游淤积情况等方面,分析了爬高型堰塞坝漫顶溃决演化过程。试验结果表明:随着土石料级配变宽,坝体整体稳定性增强溃决历时延长,洪峰流量减小,峰现时间较晚,残留溃口上宽小坝体体积大,距坝趾泥沙输移长度短且距坝趾1 m处泥沙厚度薄;背水坡面越陡,水流获得的动能越大,加速了整个坝体溃决过程,溃口扩展得到充足发育,洪峰流量增大,峰现时间提前,残留溃口上宽较大坝体体积小,距坝趾泥沙输移长度长且距坝趾1 m处泥沙厚度较厚;宽深比越大,则溃口相对位置越高,冲蚀阶段所具有的水头差大,加速了坝体冲刷进程,溃口扩展得到充分发育,残留溃口上宽尺度大坝体总量小,距坝趾泥沙输移距离远且距坝趾1 m处泥沙厚度较厚。
