Business Email Compromise (BEC) attacks have emerged as a significant cybersecurity threat, leading to substantial financial losses for organizations. According to the FBI’s Internet Crime Complaint Center (IC3), BEC attacks resulted in financial losses exceeding $1.8 billion in the USA in 2019 alone. Business Email Compromise (BEC) attacks have emerged as a significant cybersecurity threat, leading to substantial financial losses for organizations. According to the FBI’s Internet Crime Complaint Center (IC3), BEC attacks resulted in financial losses exceeding $1.8 billion in the USA in 2019 alone. BEC attacks target a wide range of sectors. No industry is immune to these attacks, which emphasizes the need for increased vigilance across all sectors. Attackers often impersonate high-level executives or vendors to gain credibility and manipulate employees into complying with fraudulent requests. BEC attacks have a global reach, with threat actors operating from various countries, including Nigeria, Russia, China, and Eastern European nations. We will examine the unique difficulties SMEs encounter in relation to BEC attacks. This study provides a more excellent knowledge of the severity of the problem and offers ideas for efficient mitigation solutions through an investigation of attack characteristics, tactics, and impacts.

Method for multi-attribute group decision-making based on the compromise weights

Multi-attribute group decision-making problems are considered where information on both attribute weights and value scores of consequences is incomplete.In group decision analysis,if preference information about alternatives is provided by participants,it should be verified whether there exist compromise weights that can support all the preference relations.The different compromise weight vectors may differ for the ranking of the alternatives.In the case that compromise weights exist,the method is proposed to find out all the compromise weight vectors in order to rank the alternatives.Based on the new feasible domain of attribute weights determined by all the compromise weight vectors and the incomplete information on value scores of consequences,dominance relations between alternatives are checked by a nonlinear goal programming model which can be transformed into a linear one by adopting a transformation.The checked dominance relations uniformly hold for all compromise weight vectors and the incomplete information on value scores of consequences.A final ranking of the alternatives can be obtained by aggregating these dominance relations.

Fuzzy distances based FMAGDM compromise ratio method and application

An extended compromise ratio method（CRM） based on fuzzy distances is developed to solve fuzzy multi-attribute group decision making problems in which weights of attributes and ratings of alternatives on attributes are expressed with values of linguistic variables parameterized using triangular fuzzy numbers.A compromise solution is determined by introducing the ranking index based on the concept that the chosen alternative should be as close as possible to the positive ideal solution and as far away from the negative ideal solution as possible simultaneously.This proposed method is compared with other existing methods to show its feasibility and effectiveness and illustrated with an example of the military route selection problem as one of the possible applications.

Comparative Research on Sino-US Agricultural Innovation Model in Science and Technology

This research was conducted to provide a comparative analysis of China's and US's agricultural innovation in science and technology and offer some guidance on the construction of agricultural innovation system in science and technology in China. The countermeasures are proposed with a hope to shorten China's and US's gap of agricultural innovation in science and technology by analyzing agricultural innovation model features in science and technology of the United States. The advantages of United States model of agricultural innovation in science and technology include sound legal framework safeguard, complete scientific and technological innovation system, high quality and talented personnel, sufficient technical development and extension funding, and extensive applications of modern agricultural high-tech. There is a gap in agricultural innovation between China and the United States. Agriculture innovation in science and technology in China should improve in several aspects such as agricultural legislation, construction of sound agricultural innovation system in science and technology, building first-class agricultural innovation and extension teams, establishing diversified channels for investment, and improving the applications of high technology in agriculture.

An efficient hash-based authenticated key agreement scheme for multi-server architecture resilient to key compromise impersonation

During the past decade,rapid advances in wireless communication technologies have made it possible for users to access desired services using hand-held devices.Service providers have hosted multiple servers to ensure seamless online services to end-users.To ensure the security of this online communication,researchers have proposed several multi-server authentication schemes incorporating various cryptographic primitives.Due to the low power and computational capacities of mobile devices,the hash-based multi-server authenticated key agreement schemes with offline Registration Server(RS)are the most efficient choice.Recently,Kumar-Om presented such a scheme and proved its security against all renowned attacks.However,we find that their scheme bears an incorrect login phase,and is unsafe to the trace attack,the Session-Specific Temporary Information Attack(SSTIA),and the Key Compromise Impersonation Attack(KCIA).In fact,all of the existing multi-server authentication schemes(hash-based with offline RS)do not withstand KCLA.To deal with this situation,we propose an improved hash-based multi-server authentication scheme(with offline RS).We analyze the security of the proposed scheme under the random oracle model and use the t4Automated Validation of Internet Security Protocols and Applications''(AVISPA)tool.The comparative analysis of communication overhead and computational complexity metrics shows the efficiency of the proposed scheme.

Molecular Dynamics Simulation of Effect of Salt on the Compromise of Hydrophilic and Hydrophobic Interactions in Sodium Dodecyl Sulfate Micelle Solutions

The presence of salt has a profound effect on the size,shape and structure of sodium dodecyl sulfate(SDS)micelles.There have been a great number of experiments on SDS micelles in the presence and absence of salt to study this complex problem.Unfortunately,it is not clear yet how electrolyte ions influence the structure of micelles.By describing the compromise between dominant mechanisms,a simplified atomic model of SDS in presence of salt has been developed and the molecular dynamics(MD)simulations of two series of systems with different concentrations of salt and charges of ion have been performed.Polydispersity of micelle size is founded at relatively high concentration of SDS and low charge of cation.Although the counter-ion pairs with head groups are formed,the transition of micelle shape is not observed because the charge of cation is not enough to neutralize the polar of micelle surface.

Impact of Sino-US Trade Friction on Import and Export Trade Pattern of Soybean in Heilongjiang

Under the background of Sino-US trade friction,soybean,as an important variety in the important and export trade of agricultural products,has become a key bargaining chip. After the Ministry of Commerce of China announced the counter list of agricultural products including soybean,the price fluctuations of domestic soybean and related agricultural products are rapidly expanding. Under the background of SinoUS trade friction,taking the soybean-producing areas in Heilongjiang as an example,the impact of Sino-US trade friction on the important and export pattern of soybean in Heilongjiang was explored to provide a certain theoretical basis for the development of soybean industry in Heilongjiang.

Coordination, Compromise, and Change： A Case of US-Japan Conflict Over Commercial Whaling

This paper, for the goal of revealing the mechanism of compromise and change in coordination, will focus on US-Japan conflict over commercial whaling. The regime like the international whaling regulation, where countries agree in general but disagree on coordination methods, is known as the Battle of the Sexes in game theory. It has been believed that in regimes presented as the Battle of the Sexes （BoS） situation, once the countries could somehow coordinate their interests and reach an agreement on the specific method of coordination, neither country would have the incentive to withdraw from that agreement. This case study, however, shows that this belief is not always true. From the analysis of this study, it will be concluded that coordination methods change over time even in regimes where the countries agree in general and disagree on coordination methods. In this case, ＂power,＂ ＂institution＂ and ＂consensus＂ are pointed out as incentives to make the two countries accept a specific coordination method.

An Analysis of Pragmatic Strategy on Sino-US Business Negotiation from the Adaptation Theory

Since China joins in WTO,its economic activities with America become more frequent. With the help of Adaptation Theory,the thesis mainly discusses on the application of adaptation strategy to Sino-US business negotiations from two ways,communicative context and language structure of adaptability. According to communicative context,the thesis states the extra linguistic factors in Sino-US negotiations,such as the mental world,the social world and the physical world of Sino-US negotiators. What's more,The thesis also discuss adaptation to language structure,such as,sound,word and syntactic structure.

A Scalar Compromise Equilibrium for N-Person Prescriptive Games

A scalar equilibrium (SE) is defined for n-person prescriptive games in normal form. When a decision criterion (notion of rationality) is either agreed upon by the players or prescribed by an external arbiter, the resulting decision process is modeled by a suitable scalar transformation (utility function). Each n-tuple of von Neumann-Morgenstern utilities is transformed into a nonnegative scalar value between 0 and 1. Any n-tuple yielding a largest scalar value determines an SE, which is always a pure strategy profile. SEs can be computed much faster than Nash equilibria, for example;and the decision criterion need not be based on the players’ selfishness. To illustrate the SE, we define a compromise equilibrium, establish its Pareto optimality, and present examples comparing it to other solution concepts.

Compromise Allocation for Combined Ratio Estimates of Population Means of a Multivariate Stratified Population Using Double Sampling in Presence of Non-Response

This paper is an attempt to work out a compromise allocation to construct combined ratio estimates under multivariate double sampling design in presence of non-response when the population mean of the auxiliary variable is unknown. The problem has been formulated as a multi-objective integer non-linear programming problem. Two solution procedures are developed using goal programming and fuzzy programming techniques. A numerical example is also worked out to illustrate the computational details. A comparison of the two methods is also carried out.

A Compromise Programming to Task Assignment Problem in Software Development Project

The scheduling process that aims to assign tasks to members is a difficult job in project management.It plays a prerequisite role in determining the project’s quality and sometimes winning the bidding process.This study aims to propose an approach based on multi-objective combinatorial optimization to do this automatically.The generated schedule directs the project to be completed with the shortest critical path,at the minimum cost,while maintaining its quality.There are several real-world business constraints related to human resources,the similarity of the tasks added to the optimization model,and the literature’s traditional rules.To support the decision-maker to evaluate different decision strategies,we use compromise programming to transform multiobjective optimization(MOP)into a single-objective problem.We designed a genetic algorithm scheme to solve the transformed problem.The proposed method allows the incorporation of the model as a navigator for search agents in the optimal solution search process by transferring the objective function to the agents’fitness function.The optimizer can effectively find compromise solutions even if the user may or may not assign a priority to particular objectives.These are achieved through a combination of nonpreference and preference approaches.The experimental results show that the proposed method worked well on the tested dataset.

The Impact of Coronavirus Disease 2019 (COVID-19) among Immune Compromised Patients in Augusta Victoria Hospital AVH-2021

Background: Coronavirus disease 2019 which is officially known as COVID-19 belongs to family viruses. COVID-19 manifestations vary among affected people. These symptoms may become more serious among patients suffering from chronic disease and those who are on treatment which may af-fect their defense mechanism or immune-compromised patients who become more vulnerable to complications of COVID-19, and at high risk for morbidity and mortality with any bacterial or viral illness. Method: A retrospective, non-experimental research design was applied with a quantitative approach among patients with COVID-19 who were admitted to COVID-19 department at AVH with a total of 72 patients. Data were extracted from a patients’ elec-tronic medical record. Results: During COVID-19 outbreak 72 patients were admitted to COVID department at AVH, 54.2% were female and 33% of study participants were from Gaza governorate followed by Jerusalem 27%. Most participants 34.7% had first clinic visit after two days from the onset of COVID-19 symptoms. 45.8% were discharged to home while 13.9% died. All inflammatory markers that include ferritin, C-RP, IL-6 and D-dimer are in-creasing in all patients that were admitted to hospital;IL-6 and D-dimer were significant inflammatory markers in relation to the mortality rate. The study found the risk of mortality with IL-6 mean (218.5), and D-dimer mean (12). Furthermore there was a relation between increased risk of mortality and im-mune comprised. Conclusion: Mortality rate increased among COVID-19 pa-tients when IL-6 was higher than 218.5 and D-dimer higher than 12, and there was a relationship between increased risk of mortality and immune comprised.

Research and Analysis of the Sino-US Agricultural Trade in Current Decade

China has a large population, so the supply of agricultural products is very essential, and agricultural trade plays an important role. According to the data from the United Nations’ commodity trade, the rate of agricultural products trade development between China and the United States is declining since 2012, and China has kept perennial trade disadvantage for a long period of time. In order to change the current trade situation, we must make in-depth analysis on the two countries’ agricultural products trade status and their characteristics, thus target to development of trade strategy. This paper first introduces the current imbalance situation of the agricultural trade between China and the United States, then analyzes the causes of trade imbalance and its impact. Finally, some relevant countermeasures are putting forward, such as expanding the scale of the economy and agriculture;narrowing the gap between international and domestic regions and improving the quality and safety of agricultural products.

Sino-US Relations: A Bumpy Path of Exploring Cooperation

January 1, 1999 marks the 20th anniversary of the establishment of diplomaticties between China and the United Slates. Over the past two decades, the bi-lateral relationship has traversed a bumpy path of a "para-strategic partnership" inthe eighties, of "cold confrontation" in the first half of the nineties and of a "rela-tively stable development" in the past two years or so. The two decades have witnessed uninterrupted explorations for a mutually ac-ceptable strategic definition of bilateral relations, which have been characterized

Giant Thoracic Meningocele Causing Acute Respiratory Compromise

Objective: The authors report a rare case of giant thoracic meningocele causing acute respiratory compromise, treated with a ventriculoperitoneal shunt. Case Report: We report the case of a 36-year-old with severe scoliosis status post repair over a decade ago, neurofibromatosis type I, and a known large meningocele in the left thoracic cavity, presenting with new acute respiratory compromise. She was taken to the operating room for a lumboperitoneal shunt, but the operation was aborted due to her severe spinal deformity. Two days later, she successfully underwent a procedure for ventriculoperitoneal shunt placement. Upon discharge a week later, the patient was hemodynamically stable, able to move all extremities with good strength, and demonstrated improved oxygenation. In the following 7 months, the patient demonstrated continued minimal requirement on nasal cannula, and MRI showed a stable left thoracic giant meningocele. Conclusion: Ventriculoperitoneal shunting is a method of treating and stabilizing acutely symptomatic giant meningoceles.
