In 1960, Senator John F. Kennedy campaigned on the issue that under the watch of President Eisenhower, a missile gap had develop between the United States and the Soviet Union. The fear of nuclear war was a grim reality, which most politicians and citizens alike understood the dire consequences. Policymakers witnessed the devastation of atomic weapons in the wake of World War ?. The vaporization of two Japanese cities, awoken the world to the power of nuclear weapons. In efforts to prevent the duplications of these disasters, policymakers committed themselves to the mastery of space, international treaties, and the development of defensive measures and alert systems. While the threat of nuclear weapons is far from over, policy makers understood the severity of these weapons, the consequences of their use, and worked to prevent annihilation. The arms race was a key component of the deterrence strategy which defined defense policy in that era. It rested on the principle that the Soviet Union should not develop technological superiority over the United States. The belief was that should a missile gap develop and the Soviet Union was to gain more weapons then the United States, America would be doomed in nuclear holocaust. A competing viewpoint was held by the Soviet Union which feared the American's nuclear superiority as well.We stand at the threshold of developing a new arms race ~ one represented no longer by a gap of nuclear warheads, but a gap in digital supremacy. The world is evolving into a dangerous new world, with stakes higher than ever. Perhaps since policymakers have never witnessed the devastation of a large scale cyber-attack, they do not truly understand the serious threat which a cyber-attack presents. The United States' failure both to dominate the electro- magnetic spectrum for military purposes, the failure to secure our digital infrastructure, in wake of the rapid cyber development of other nations, presents the most immediate threat to national security. We are only as safe as we allow ourselves to be, and we need to act quickly to begin removing the vulnerabilities within our computer systems. It only takes one successful hacker, to end the way of life in America we know. The National Nuclear Security Administration, which oversees the U.S. nuclear weapon stockpile, is attacked nearly 10 million times a day (Koebler, 2012). In an ever grimmer reality, one successful attack could end all life on earth. Is this a risk we are willing to take? National Security depends upon cyber-security.One of the best examples of this of the threats of society comes from August 2008, during the South Ossetia war between Russia and Georgia. During the military campaign in Georgia, Russian naval hackers methodically launched cyber-attacks on Georgia (Bukkvol, 2009). These hackers destroyed Georgian internet servers crippling and disrupting communication throughout Georgia (Walsh, 2009). The Georgian government could not match the technical superiority of Russia, and was forced to rely upon Estonia and Poland for technical assistance (Markoff, 2008). The Russian Naval hackers then infiltrated the Georgian Power grid; block by block they powered down cities as Russian ground forces moved in for occupation.Russia is not the only nation to demonstrate such capabilities. The United States began flexing its own cyber-muscle during the Bush Administration. Late in 2007, the National Security Agency (NS A) launched one of the largest and most successful cyber-attacks to date (Harris, 2009). The NSA attacked cell phones and computers that counter insurgents in Iraq were using to plan and coordinate roadside bombings (Harris, 2009). This operation was not only a successful military strike on enemy forces, but it was successfully achieved without risking the safety of American personnel.While cyber- warfare is still secondary to traditional warfare, there are graver threats lurking in cyberspace. Cyber-spying is one of these prominent threats. …


A cyber-physical system (CPS) is a composition of an embedded computer, a network and a physical process. Usually, the plant, which represents the physical part, is controlled by an embedded system, which consists of computation, communication and control elements, via the global network. This contribution focuses on networked control systems (NCSs) which represents a specific class of CPS. As the problems of CPSs and NCSs are quite similar the goal is to transfer well developed techniques of NCSs to CPSs for analysis purposes. NCSs deal with the analysis of the interaction between the physical system and the cyber system. A main challenge of a control engineer is the development of stable and robust controllers for a NCS. The same goal is present in the design of CPS. To ensure this goal the analysis of such a feedback system has to be performed which is not straight forward and limited by the used modeling approach. This work compares different state-of-the-art modeling approaches for NCSs and stability analysis methods therefore.

Tenet Healthcare Corp.'s acquisition of Vanguard Health Systems is a sign the investor-owned chain is willing to take a chance on alternative payment models such as accountable care organizations. There's no certainty that ACOs will deliver the improvements on quality or cost savings, but Vanguard Vice Chairman Keith Pitts, left, says his system's Pioneer ACO in Detroit has already achieved some cost savings.


The materials of the article consider the analysis of construction materials of active zones of new generation nuclear reactors. The analysis reflects general ideas about the development of reactor technologies: in the 1950s and 1960s, the first generation of reactors was created; in the early 1970s, the operation of industrial reactors began - reactors of the second generation: pressurized water reactors (WWER, PWR), boiling water reactors (RBMK, BWR), heavy water reactors (CANDU), as well as gas-cooled reactors (AGR). Further development of some types of reactors made it possible to create reactors of the third generation in the 1980s. Priority when choosing directions of development in the category of revolutionary projects should have proposals capable of bringing a new quality to solving the problems of the nuclear energy industry of the future. Promising reactors have advantages in economy, safety, reliability and non-proliferation of nuclear materials. The effectiveness and reliability of structural materials are determined by the totality of changes in the characteristics of the materials as a result of the entire complex of phenomena occurring in them in the field of irradiation, in connection with the changing parameters and operating conditions. The use of high-purity metals as initial components of new structural materials and the development or optimization of their smelting technologies should ensure the required level of characteristics and properties of products made from them. The implementation of these concepts should be ensured by the development of new structural materials: ferritic-martensitic and austenitic steels, nickel and other new alloys.


Several chemical and biological studies have revealed R,S-goitrin as the main bioactive constituent of Isatis indigotica Fort., responsible for antiviral antiendotoxin activity; however, few pharmacokinetic studies have been conducted. To comprehend the kinetics of R,S-goitrin and promote its curative application, a rapid and sensitive UHPLC-MS/MS method was developed. The selected reaction monitoring transitions were m/z 130.0 → 70.0 for R,S-goitrin and m/z 181.1 → 124.0 for the internal standard in a positive-ion mode. The established UHPLC-MS/MS method achieved good linearity for R,S-goitrin at 10-2000 ng/mL. The intra- and interday accuracy levels were within ±9.7%, whereas the intraday and interday precision levels were <11.3%. The extraction recovery, stability and matrix effect were within acceptable limits. The validated method was successfully applied for the pharmacokinetic analysis of R,S-goitrin in rats after oral administration. Moreover, a total of six metabolites were structurally identified through UHPLC-Q/TOF-MS. The proposed metabolic pathways of R,S-goitrin in rats involve demethylation, acetylation, glutathionylation and oxygenation.


PURPOSE: To reduce the power loss when the phase current of a polyphase motor is switched by means of a switching transistor under control of a pulse width modulation signal. CONSTITUTION: When any one of switching transistors 25, 26, 25', 26', 25", 26" for a active coil among the coils 10, 11, 12 of a motor through which a current is flowing is turned on during a PWM mode chopping period, a nonrectified ground return path is provided for the flyback energy in the active driving coil.

In the early 1920s, Edmund Husserl published a series of essays on renewal in the Japanese journal Kaizo , discussing human life, its goaldirected, teleological nature and its possibilities for self-regulation. Husserl focused on the problems of individual transformation and social-cultural development and argued that human life should not be modelled on biological life. Human life and animal life include similar elements, such as drives, needs and feelings, but these moments can become objects of reflection and critical inspection only within human life, and can thus receive a rational justification. This chapter explicates Husserl's idea of ethical life in distinction from the other possible types of human life. It then discusses the personalistic emphasis of Husserl's approach and the secondary role that the other person has in it. The chapter clarifies Husserl's understanding of ethical selfawareness.

1. Introduction. An analytic disk in C n is a map f : D → C n , where D is the closed unit disk, which is holomorphic on the open disk D o and smooth up to the boundary. One can also consider disks that are not smooth at every point of bD. An H ∞-disk is a bounded holomorphic map f : D o → C n. One says that the boundary of f is contained in a compact set X ⊆ C n if the almost-everywhere defined boundary values f * (e iθ) are contained in X for almost all θ. The maximum principle shows that f (D o) is contained in the polynomially convex hull of X. There is also an intermediate notion of a nearly smooth analytic disk (n.s.a.d.); this is an H ∞-disk f : D o → C n that extends to be smooth on all of D except for (at most) a single point of bD (usually taken to be 1 ∈ bD). One says that the boundary of f lies in X if the image by f of bD with the single point deleted is contained in X. The main result of [A] is that if L is an n-dimensional compact totally real manifold in C n , then there exists a nonconstant n.s.a.d. with boundary in L. This was proved by adapting an argument of Gromov [G] that was a cornerstone in his theory of pseudoholomorphic curves. Gromov's theorem, for the special case of C n , is that if L is an n-dimensional compact Lagrangian manifold in C n , then there exists a nonconstant analytic disk with boundary in L. The object here is to obtain more information about these disks. Our motivation comes from the simple example of the standard torus T 3 in C 3 , where there are analytic disks in each of the three " faces " { Our result is that, analogously, contained in each of the faces (appropriately defined) associated with an n-dimensional totally real L in C n , there is a nonconstant n.s.a.d. with boundary in L. Likewise, in the Lagrangian case considered by Gromov, there exists a nonconstant analytic disk in each face. As with T 3 , the faces associated with L are related to the images of L under complex linear maps. Let φ be a complex …


This paper uses aspects of the type of Nachtraglichkeit, or deferred action, as described by Hal Foster in "The Return of the Real" (1996) to recover Franz Marc's utopian visions of Eden as shown in the mural Marc made with August Macke called "Paradies". Traces of Marc's ideas about animals and utopia can be found in Joan Jonas's 2009 "Reading Dante," an installation from the 2009 Biennale di Venezia, and in the video "Girl and the Sea," directed by Lee Lennox to accompany the 2004 song of the same name by the Presets.


This chapter reviews current methods and findings of physiological research studies on persistent violence and aggression, antisocial personality disorder (ASPD), and psychopathy. The review begins by describing how ASPD and psychopathy, two clinical conditions that are commonly associated with violent and aggressive behaviors, are assessed and measured in contemporary investigative work. Following this, the chapter discusses differing physiological measurement methods that have been used in the study of these conditions and in relation to aggression and violent behavior more specifically. A detailed review of autonomic, somatic, electrocortical, and neuroimaging methods and findings is provided. Following this, the chapter provides coverage of key conceptual issues pertaining to the use of physiological measurement in assessing psychiatric phenotypes and psychological processes central to them. Directions for future research are discussed in this context.

Summary A method is described for the determination of xanthine oxidase in milk with triphenyl tetrazolium chloride. The enzymatic reaction is performed with nitrogen gas bubbling through the mixture to avoid oxygen which is inhibitory. Subsequent steps, which include extraction of the color with toluene after acidification with acetic acid, are performed in air since the red, reduced form of triphenyl tetrazolium chloride is stable. The effects of concentration of substrate and triphenyl tetrazolium, and other factors are investigated. The method is used to show the destruction of xanthine oxidase in skimmilk at 55 to 75° C.


These days, just like other industries mechanical industries are also shifting towards the automation by using various techniques like machine learning, nano technology, 3D printing, etc. From 19th century steel has been widely used for construction purposes especially TMT rod(thermo mechanically treated rod).In steel industries conventional methods have been widely used for predicting the quality of steel.These conventional methods are not so accurate as well as some times they are unable to identify the errors along with this they consume a large amount of time. we have proposed a machine learning technique by which microstructures of steel are compared from any dataset of images, in order to find the differences and from the obtained differences ,the component which have less amount of defects can be obtained.


A 16-year-old girl disappeared from her home 3 months back and was discovered recently by her parents in a hospital from which they shifted her to our centre. She had cigarette stub burns on her wrist and abdomen (Figure 1). She was in altered sensorium, when we examined her along with signs of meningeal irritation (neck rigidity, Kernig's, etc.). Gynaecological evaluation revealed a torn hymen, and a CSF analysis performed immediately showed pus with a total leucocyte count of 28,000, predominantly neutrophils and c/s after 48 h grew pneumococcus sensitive to penicillin (Figure 2). She was immediately started on intravenous penicillin in standard meningitic doses after which her sensorium recovered.

A normalized RC-FDTD algorithm is applied to study both the bistatic and monostatic radar scattering of perfectly conducting sphere covered with inhomogeneous unmagnetized plasma. The effects of electron density distributions and plasma collision frequencies on the radar cross section (RCS) are discussed respectively. The simulations confirm that plasma cladding can be successfully used to reduce the RCS of a conducting sphere at almost all scattering angles, although the RCS could increase at some other angles. And the back scattering results indicate that plasma cladding can reduce the RCS of the conducting sphere in a very wide frequency range. Reasonable selection of the plasma parameters can enhance the effectiveness of plasma stealth.


For glass systems related to two potential nuclear-wasteglasses, ABS–39 and ABS–41, the 600°C isotherm of the metastable immiscibility field has been located experimentally. Both glasses are in the one phase glass field down to temperatures below 600°C. ABS–39 and ABS–41 are Na 2 O-B 2 O 3 -SiO 2 glasses containing 1.66 wt% UO 2 and 9 wt% of simulated fission products. Additional components in ABS–39 are Al 2 O 3 and Fe 2 O 3 . In ABS–41 these two oxides are partly substituted with ZnO and Li 2 O. This substitution causes an extension of the metastable immiscibility field relative to the ABS–39 system.

By successfully applying the knowledge of the structure and function of latissimus dorsi (lat) muscle into my advanced yoga practice, I could be able to rehabilitate my shoulder problem up to a great extent – You can see the difference in the time‐lapse photographs of my body showing striking improvement in my condition.


The National HIV Surveillance Report estimated that by the end of 2008, there were approximately 1.2 million people living with human immunodeficiency virus (HIV) in the United States. Despite the decline in mortality from HIV, the incidence rate has remained steady, at approximately 50,000 cases per year. These startling incidence numbers speak of our helplessness in containing HIV transmission, fostering efforts toward developing robust prevention strategies. Earlier approaches focused on the consistent use of barrier methods, mandatory HIV blood bank screening, behavior modification, and postexposure prophylaxis. Of late, adult male circumcision, HIV vaccination, and vaginal microbicide have been assessed in various trials with varying outcomes. There is no doubt that antiretroviral therapy (ART) has proven effective and remains promising in curbing the spread of HIV infection. The Preexposure Prophylaxis Initiative study showed significant protection in a population at high risk, specifically men who have sex with men. Preliminary results of ongoing oral preexposure prophylaxis (PrEP) studies TDF2 and Partners PrEP confirmed protection against HIV transmission in women. In the Partners PrEP study, tenofovir (TDF) was effective in 68% of women and 58% of men versus placebo, and TDF/emtricitabine (TDF/FTC) was effective in 62% of women and 83% of men. None of the differences between men and women or between TDF and TDF/FTC was statistically significant. In the TDF2 trial, TDF/FTC was effective in 80% of men, compared with an efficacy of 49% in women; however, the study was underpowered to assess the difference between the two groups. These studies have incited international attention toward oral PrEP as a plausible answer to curb the HIV incidence rate. Many PrEP trials to assess this novel tool are under way (Table). Furthermore, the Joint United Nations Programme on HIV/AIDS has dedicated US$ 1.19 billion funding for HIV prevention research, focused mainly on ART PrEP, HIV vaccine development, vaginal microbicide, and male circumcision intervention. In this issue of the Southern Medical Journal, Tripathi et al present a questionnaire survey to assess health care providers' knowledge, attitudes, and perceptions regarding PrEP in two southern US states. The results are remarkable for the high degree of acceptability and support for the future implementation of PrEP. A high percentage of respondents agreed with empowering women for the prevention of HIV transmission. This is a pertinent and often overlooked determinant in HIV transmission. In Sub-Saharan Africa, where the majority of new HIV infections occur, women represent nearly 60% of adults and in most cases acquire HIV through sexual intercourse with an infected male partner. PrEP may help address the urgent need for a female-controlled prevention method worldwide for women who are unable to negotiate condom use with their partners. The study is timely because it can help identify unmet needs, gaps in knowledge, cultural beliefs, or behavioral patterns in the study area. In turn, this would facilitate optimal resource use, augment strategic decision-making capability by the authorities, and help customize implementation tools when PrEP is implemented at the grassroots level. Interestingly, Tripathi et al conducted this study before the availability of the results of major PrEP trials. Higher acceptance rates may be expected among the respondents if the study were to be conducted now, given the encouraging results of various PrEP studies. Implementation of PrEP is marred by various formidable challenges. Its use is likely to be limited to the population of individuals at high risk. The unknown safety profile of longterm ART, especially TDF/FTC in HIV-uninfected individuals, is concerning. Other deterrents include enforcing strict adherence among users, high-cost involvement that would limit its utility in resource-restricted settings, development of multidrug-resistant viral infection in case of PrEP failure, determination of the optimal frequency of testing and safety monitoring, and risk compensation. A holistic approach that integrates the available prevention strategiesVbehavioral changes, consistent condom use, timely diagnosis and treatment of sexually transmitted diseases, regular testing for HIV, monogamy, and PrEPVare plausible steps toward containing the incidence of HIV. Although PrEP certainly appears to be a step forward in the battle against HIV, it may inadvertently be a step backward if it results in overzealous risk compensation, drug resistance, and exorbitant costs of development and implementation. A highly cautious interpretation of results of PrEP trials, especially at the implementation level, is warranted. Editorial

Abstract The data described in this paper suggest that an initial trait judgment will sometimes reduce the time it takes for a judge to make a later trait judgement. Three separate types of facilitation were apparent. The first of these was ageneral practice effect:subjects simply got faster at making trait judgments with increasing practice at the judgment task. The second of these was ashort-term specific facilitation effect:With no items intervening between two successive trait judgments, the second judgment was speeded when the trait term used in the second judgment was: (1) the same as used in the first judgment; (2) a synonym of the trait term used in the first judgment; or (3) an antonym of the trait term used in the first judgment. The third of these was along-term specific facilitation effect:With multiple items intervening between the two trait judgments, responses were speeded only when the trait used in the second judgment was the same as used in the first judgment, or was a synonym of the trait used in the first judgment; no facilitation occurred when the second trait judgment involved an antonym of the trait used in the initial judgment. Results are discussed in terms of various models describing the cognitive representation of trait concepts.

Legislators are representatives of their constituencies, they initiate and monitor development projects, link their constituencies with both state and national government and generally help in improving the quality of life for members. This study set out to find out how legislators' are able to locate and access information that may influence their performance.The survey research design was used. The population consisted of all the 177 legislators from all the six state houses of assembly in South-West Nigeria. The Cronbach's alpha was used to validate the questionnaire which gave a reliability coefficient of 0.188. The return rate was 85.3%. Data were analyzed using descriptive statistics, Person moment correlation and ANOVA. Findings showed that legislators (64%) had a clear understanding of the information they needed for their constituency work, as the lawmakers (65%) were able to locate and access information from current awareness sources such as newspapers and radio. Legislators (35%) also found it easy to retrieve information from community based sources such as traditional and religious leaders as well as NGOs (31%). For the hypothesis, the correlation coefficient of the information skills, abilities measured revealed that for locating and accessing information (0.18p-value<0.029) had low significant positive relationship between them and their constituency performance. The null hypothesis were therefore rejected, that is the coefficient of determination (R2) 0.188 which signified all the skills accounted for about 19% validity in the lawmakers constituency performances.


In the framework of MPEG-4 hybrid coding of natural and synthetic data streams, one can include teleconferencing and telepresence applications, in which a synthetic proxy or a virtual agent is capable of substituting the actual user. Such agents can interact with each other, analyzing input textual data entered by the user and multisensory data, including human emotions, facial expressions and nonverbal speech. This not only enhances interactivity, by replacing single media representations with dynamic multimedia renderings, but also assists human–computer interaction issues, letting the system become accustomed to the current needs and feelings of the user. Actual application of this technology [1] is expected in educational environments, 3-D videoconferencing and collaborative workplaces, online shopping and gaming, virtual communities and interactive entertainment. Facial expression synthesis and animation has gained much interest within the MPEG-4 framework; explicit facial animation parameters (FAPs) have been dedicated to this purpose. However, FAP implementation is an open research area [2]. In this chapter we describe a method for generating emotionally enriched human–computer interaction, focusing on analysis and synthesis of primary [3] and intermediate facial expressions [4]. To achieve this goal we utilize both MPEG-4 facial definition parameters (FDPs) and FAPs. The contribution of the work is twofold: it proposes a way of modeling primary expressions using FAPs and it describes a rule-based technique for analyzing both archetypal and intermediate expressions; for the latter we propose an innovative model generation framework. In particular, a relation between FAPs and the activation parameter proposed in classical psychological studies is established, extending the archetypal expression studies that the computer society has concentrated on. The overall scheme leads to a parameterized 144 EMOTION RECOGNITION AND SYNTHESIS BASED ON MPEG-4 FAPs approach to facial expression synthesis that is compatible with the MPEG-4 standard and can be used for emotion understanding.

This article examines the current state of this technique in Canada and offers recommendations and strategies to overcome challenges still present in an attempt to further advance the application of this extremely versatile technique.


Although the virus has not yet been isolated, all the available evidence suggests that infectious hepatitis is a viral illness. Failure to isolate the virus or viruses responsible means that specific antibodies to the virus antigen cannot be produced in the laboratory, neither can the virus be modified artificially and used to evoke active immunity. After an attack of infectious hepatitis an individual is usually immune from further attacks; the antibodies responsible for the immunity are contained in IgG fractions of the gamma globulin.


We consider in this article the weakly coupled system of wave equations in the \textit{scale-invariant case} and with time-derivative nonlinearities. Under the usual assumption of small initial data, we obtain an improvement of the delimitation of the blow-up region by obtaining a new candidate for the critical curve. More precisely, we enhance the results obtained in \cite{Palmieri} for the system under consideration in the present work. We believe that our result is optimal in the sense that beyond the blow-up region obtained here we may conjecture the global existence of the solution.


New maleic anhydride-β-cyclodextrin functionalized magnetic iron oxide nanoparticles (IONPs@MAH-β-CD) were prepared through the simple chemical coprecipitation method. Macroscopic batch experiments were carried out to study its absorption behavior for uranium (VI) under different environmental conditions. Using the magnetic separation technique, it was possible to easily separate IONPs@MAH-β-CD from uranium-containing wastewater. The equilibrium for uranium (VI) adsorption was reached for 180 min. The results showed that the kinetics and isotherm of the adsorption process were consistent with the pseudo-second-order kinetic model and Langmuir model, respectively, indicating that it was a chemisorption process. Compared with pure IONPs, the maximum adsorption quantity of maleic anhydride-β-cyclodextrin-coated iron oxide nanoparticles for uranium (VI) was significantly improved, which could reach 163.93 mg g−1. The recyclability of the IONPs@MAH-β-CD was investigated, and FTIR and XPS characterization were used to explore the possible mechanism of U(VI) adsorption.

BACKGROUND: Adequate administration of Rh immune globulin requires an accurate determination of the number of D‐positive cells in the circulation of D‐negative women. Although several tests have been described for the detection of fetomaternal hemorrhage, there is still a need for a rapid, simple, and clinically relevant screening test. STUDY DESIGN AND METHODS: Serial dilutions of a monoclonal anti‐D were incubated with stock solutions (0.2 mL) of adult D‐negative red cells in the absence or presence of various amounts of fetal D‐positive cells (0.1, 0.2, 0.3, 0.4, and 0.5%). After incubation, the supernatants were tested against D‐positive red cells by using the new, gel agglutination technique (GAT). After the GAT was adapted to detect D‐positive cells at concentrations of > or = 0.2 percent, unselected postpartum samples from D‐negative women (n = 420) who delivered D‐positive infants were analyzed by both the new test and the Kleihauer‐Betke test (KBT). RESULTS: Three of a total of 420 postpartum samples were positive (> or = 0.4% fetal cells), and 406 were negative in both tests. One had 0.5‐ percent fetal cells in the KBT and gave negative results in the GAT. The latter test was, however, performed after administration of Rh immune globulin. The KBT gave false‐positive results in two cases, because of hereditary persistence of hemoglobin F, and the GAT gave a false‐positive reaction in one case because of a maternal weak D variant. In the remaining seven cases, the KBT results were only weakly positive (0.2%) and could not be attributed solely to D positive red cells. CONCLUSION: The GAT is suited for routine screening. It provides rapid and specific detection of D‐positive red cells at clinically relevant concentrations. The test may (rarely) yield false‐negative results due to insufficient administration of Rh immune globulin before testing.

The syphilis and COVID-19 pandemics have marked a turning point in the history of mankind. The aim of this review is to analyze what two pandemics caused by different diseases have in common. It is a scoping review made up of papers covering everything related to syphilis and COVID-19. The dialectical structural model of care (DSMC) is applied, focusing on three thematic plots that explain the historical and current context of the topic addressed. To this end, we compiled information from books, journals, and databases such as Cochrane, National Library of Spain, PubMed/Medline, Scielo, and Google Scholar. Syphilis is a bacterial disease transmitted sexually. COVID-19 is a viral infection transmitted by droplets. Despite their similarities and differences, both have triggered pandemics that have claimed the lives of thousands of people. Both still exist as active diseases. The origin of both remains a scientific enigma; many human and material resources have been devoted to tackling these two infections, and a wide range of drugs have been developed to combat them.


In their working state, molybdenum based hydrotreating catalysts are known to contain poorly crystallized MoS 2 particles with one or several slabs in interaction with the alumina surface. Two morphological parameters are important regarding the activity and selectivity of these particles namely the length and the stacking of the molybdenum sulfide slabs.


the disease in its prodromal phase. Unfortunately, there is no biological marker for AD that can reliably identify the disease. Brain imaging may be more useful, but its real value at this stage remains to be established. Specific memory tests are the most helpful because the pattern of memory deficits of patients with prodromal AD has been clearly defined. To conclude, the main issue is to define what is useful for a given individual. Is it to diagnose MCI, a syndrome of unknown aetiology, or to detect the disease that is responsible for most of the cases, i.e. incipient AD? The question is opened.

A compact three-dimensional four-way vectorial steering module using low-temperature co-fired ceramics multi-layer technology, hybrid-integrated with monolithic microwave integrated circuits, for flexible satellite payloads operating in the Ka-band downlink frequency range of 17-22 GHz is presented. The module features digitally controllable actuators and hermetic sealing at a compact size of 26 mm × 44.5 mm × 4.4 mm. For feeding the module with a single input signal, a one-stage four-way Wilkinson power divider was designed incorporating buried resistors, fabricated, and measured. The divider exhibits a measured return loss of better than 13 dB at the input port and 16 dB at the output ports. The output port isolation exceeds 20 dB, the transmission phase difference remains below 3.1 degrees, and the insertion loss is less than 1.2 dB. The vectorial microwave parameters of the module can be adjusted by 344 degrees for phase and 15.5 dB for amplitude, with 5-bit resolution, and at step sizes of 11.25 degrees and 0.5 dB, respectively. The measured results show that the RMS phase and amplitude errors remain below 3.8 degrees and 0.23 dB.


Nowadays, the Internet is being utilized increasingly more for communicating real-time (multimedia) data to multiple recipients, i.e., multicasting. Our goal is to investigate the network processing operations that are involved in supporting multicasting and to determine which operations are time-critical. Traditionally, investigations on such routers have been focussing on packet forwarding and functionalities of other protocols found in lower layers of the TCP/IP protocol stack. In this paper, we present our investigation of the Internet Group Management Protocol that belongs to a higher layer of the TCP/IP protocol stack. The methodology encompasses the creation of benchmarks reflecting the IGMP functionalities and subsequently the profiling of the created benchmarks in order to determine the most time-critical operations. Next to determining the timecritical operations, the mentioned simulation environment also provided results on instruction distribution, cache behavior, and branch prediction accuracy. Preliminary results suggest that the operations involved in multicasting are memory-intensive as about 50% of the operations are memory-related operations. Such results can be utilized in the design of future network processors. Keywords— Benchmarking, profiling, multicast, IGMP, videoconferencing.


Power electronic converters are increasingly used in power systems. However, they are vulnerable components and prone to aging failures, thus affecting overall system reliability. Therefore, their availability modeling especially in large-scale power electronic-based power systems is of paramount importance. This letter introduces four different approaches for converter availability modeling considering aging failures under different maintenance strategies. The accuracy and calculation burden of these approaches are illustrated by numerical analysis. It is shown that the method of device of stages and piece-wise approach are the most applicable methods in the case of corrective and preventive maintenance strategies respectively.


Maternal mortality ratio (MMR) of non-developing and developing countries stipulate that every year an enormous number of pregnant women succumbed to death due to lack of proper healthcare service. In the case of Bangladesh, maximum maternal deaths happen in the rural and hill-tracts area due to the communication gap during the emergency moments. To solve this situation, in this study, we have proposed multiple sensor-based systems that focus on the issue of complete health monitoring of an expecting mother. We envisioned to target the expecting mothers who are most of the time-deprived of complete health monitoring during the pregnancy time. Our developed system consists of non-invasive anemia and glucose rate detection, sudden fall detection, heart rate, and body temperature. We have also incorporated Wi-Fi and GSM modules in our device to make it viable for telemonitoring. To monitor all these physical parameters, we have also introduced a custom-made android application. These would allow the expecting mothers to assess their health conditions. The doctors and family members would also get notified through SMS if there is an emergency. The outcome of this research would help the health service providers to envision a different approach to give proper healthcare facilties to expecting mothers, specially in the rural areas.

In this article, we propose a web back-end database leakage incident reconstruction framework (WeB-DLIR) over unlabeled logs, designed to improve the intelligence and automation of reconstructing web back-end database leakage incidents triggered by web-based attacks in unannotated logging environments. Using WeB-DLIR, analysts can reduce the manual workload of tracing and responding to data leakage incidents. Specifically, we first design web front-end and back-end anomaly identification methods based on neural network models with a pruning strategy and fine-grained grouping clustering analysis, respectively, for completely identifying web-related abnormal events in unlabeled logs. To remove redundant abnormal events and reduce subsequent inspection work for false alarm cases, we then propose an anomaly detection result decision fusion method (DFADR). Moreover, to visualize the attack chain reflected by abnormal events, based on the decision fusion results, we propose an attack graph modeling method that can reflect the basic process of data leakage from multiple perspectives. Finally, based on the modeling results, the topology of the data leakage scenario reconstruction can be completed by further auditing the relevant logs. Experimental results using real-world datasets show that the proposed WeB-DLIR is efficient and feasible for practical applications.


This special issue is dedicated to Ted Belytschko, the late Walter P. Murphy Professor and McCormick Institute Professor of Computational Mechanics at Northwestern University and Editor of the International Journal for Numerical Methods in Engineering since 1997, jointly with Roland W. Lewis, and as Editor-in-Chief from 2007 to January 2014. Ted Belytschko has made seminal contributions to computational engineering. He was a prolific writer and one of the most cited researchers in engineering science, a recipient of numerous honours and prizes, including membership of the National Academy of Sciences, the National Academy of Engineering, the American Academy of Arts and Sciences, and recipient of the John von Neumann Medal (2000), the Gauss–Newton Medal (2002), the Timoshenko Medal (2001), the Theodore von Kármán Medal (2001) and the William Prager Medal (2011). An obituary to Ted was published in the Journal‡ after he passed away on September 15, 2014. In his capacity as Editor, and subsequently as Editor-in-Chief of this Journal, he has seen many changes, such as the introduction of the electronic submission system. He has actively tackled the challenges that came with the electronic submission system, has exercised a strict quality control and has kept the Journal close to its roots. Upon his retirement as Editor-in-Chief in January 2014, it seemed most fitting to invite a number of distinguished colleagues among his large circle of friends to contribute an article to a Special Issue honouring his accomplishments in computational mechanics. Unfortunately, Ted passed away before the Special Issue could be completed. Hence, this tribute is now in memory of him. The Special Issue consists of 29 contributions and reflects research topics on which Ted Belytschko has worked: eXtended finite element methods, multiscale analysis and scale bridging, computational damage and fracture mechanics, element technology and stabilisation, and structural dynamics.


The capability of islanding detection has become a requirement for grid connection of inverters utilized in distributed generation (DG) systems. The parallel RLC resonant circuit comprised, as a local load, in the standard test of islanding detection schemes offers lower impedance for higher frequency harmonics. With the presence of such a parallel RLC circuit, the full power balance between the distributed generation and local load will never be satisfied when the voltage at the point of common coupling is slightly distorted. In this paper, the performance of grid-connected inverter during islanding detection routine test is analyzed with sinusoidal and marginally distorted grid voltage. The results presented in this paper show that grid background harmonics may have significant impacts on inverter control and islanding detection algorithms.


With lower alloying costs and higher mechanical properties, lean duplex stainless steels can be a good alternative to the more commonly used austenitic stainless steels. A study was initiated to define the limits of the use of lean duplex stainless steels for urban wastewater treatment (WWT) units. This paper gives and discusses the corrosion results in an aerated wet atmosphere containing H2S at different levels. Exposures were performed both at laboratory scale and in the field WWT plant for 1 year. A specific probe was also designed to study the corrosion process below water condensate film contaminated with H2S. Under such conditions, the properties of stainless steel were strongly modified with an enhanced risk of localized corrosion. The results obtained on lean duplex materials (UNS S32101, S32202, and S32304) are compared with austenitic UNS S30403 and UNS S31603 and with the more standard duplexes UNS S82441 and UNS S32205. The results show that lean duplexes can be used in aerated wet atmospheres in case of moderate contamination of H2S (<10 ppm) and chloride (<200 ppm). For higher contaminations (e.g., H2S around 100 ppm/chloride around 1000 ppm) the duplex S32205 should be preferred.


Background: Oral cancer is one of the sixth most common cancers in the world. Oral exfoliative cytology is one of the popular screening tool for oral cancer. Use of tobacco in any form are documented as the most common cause as initiators for dysplastic changes in oral mucosa. The purpose of the study was to detect the cytological changes in buccal mucosa, tongue and palate among non-smokers smokers. Material Methods: Smears sample were collected according to site (buccal mucosa, tongue palate) from 100 subjects among smokers non-smokers. Smears were then stained using Papanicolaou staining technique. Results: Among the smokers and non-smokers the results were statistically significant. Conclusion: Recent advances in the clinical visualization and detection of the oral mucosa have made the viability of cytological procedures more specific and sensitive. Contact endoscopy and use of autofluorescence devices are the forerunners in this group. The fluorescence characteristics of tissues depend upon their biochemical composition and histomorphological architecture, both of which undergo a change during malignant transformation. These changes are detectable as an alteration in the fluorescence spectral profile of the tissues21. Due to low feasibilities of such devices the benchmark of diagnosis will be microscopic tissue examination. Hence cytological smears will always be highly specific, sensitive, easy to use and reproducible procedures in routine screening of population for potentially and malignant conditions of the oral cavity.


This post seeks to briefly outline the legal issues that Australian universities should be aware of in relation to the delivery of online teaching.

This paper examines the effect of the ownership structure (of debt and equity) on the agency problems of debt. This issue is particularly relevant for Japanese keiretsu firms. Member firms in a keiretsu are linked through business ties and reciprocal shareholdings. A central figure of the keiretsu is the main bank that serves as a corporate monitor. We hypothesize that the main bank's monitoring intensity varies with the degree of its keiretsu member banks' financial interests in the member firms. We first find that the leverage of keiretsu firms in our sample is significantly negatively related to proxies for the source of potential agency conflicts (e.g., R&D expenditures and intangible assets), implying that Japanese keiretsu firms also suffer from agency problems of debt. This is contrary to the popularly held view that Japanese firms are free of agency problems of debt since banks are often both large creditors and shareholders. We then consider the ownership structures based on debt and equity holdings by member banks and member firms within the same keiretsu. Consistent with our hypothesis, our empirical results show that agency costs of debt are pronounced among firms in which the members have low-debt and low-equity holdings, but are mitigated substantially for other firms in which the members have significant holdings of debt and/or equity, in the order of low debt and high equity, high debt and low equity, high debt and high equity.


To evaluate the effectiveness of amikacin administered by autoinjector compared to manual injection on infected excision wound model of Wistar rats. Randomly bred 14 Wistar rats of either sex weighing 180 to 230 g were used for the present study. The study has the approval of the Institutional Animal Ethical Committee. Pseudomonas aeruginosa was used for infecting the wounds.1mL of bloodwaswithdrawn aseptically from the orbital sinus under iso lurane anaesthesia, and the biochemical parameters were carried out. All results were expressed asmean± SEM, and the results were compared statistically by one-way ANOVA using Sigma Plot 13. P-value < 0.05 was considered statistically signi icant. The biochemical parameters in the study was more or less similar. The infected rats treated with amikacin showed faster wound contraction compared to control. This study concludes the effectiveness of amikacin administered through autoinjectors andmanual injection in infected excision wound model as similar. Therefore, amikacin autoinjector is a better choice to manual injection to overcome from wound infections if it is administered at the right time in case of emergency or whenever required. Injury and wound infection are common in natural and manmade disasters. Serious bacterial wound infections are a potential threat to open injuries. As accessibility to the primary health centre or hospital may not be easy or possible during disasters and to overcome such a situation, an antibacterial autoinjector would be useful.


Knowledge Management (KM) comprises a range of practices used in an organization to identify, create, represent, distribute and enable adoption of insights and experiences. Such insights and experiences comprise knowledge, either embodied in individuals or embedded in organizational processes or practice. Knowledge Management portal is one of the important process of the total KM program of any organization. It helps in creating a platform for knowledge contribution, sharing and discussing for the employees of the organization. Important knowledge gaps can be identified and promoted here. Advantages of web based knowledge management system are that it is easy to maintain as development requirements are limited to the server side. Changes can be done to the system easily and continues improvement can be done to the system. This paper deals with a case study of Knowledge Management implementation in R&D Centre for Iron & Steel (RDCIS). Here different groups carry out projects and provide technological services in their respective domains. The various outputs of the technical groups include Projects, Papers, Publications, Copyrights, Patents, Technology Awareness Programs etc. This information is mostly maintained in document forms and not available on-line for ready access by all concerned. Intranet based web application called "RDCIS Information Portal" is a gateway to access these information and knowledge base available at RDCIS. The portal is supplemented by on-line applications enabling access to information and knowledge through a single window. It has also provision to capture and share explicit as well as tacit knowledge. Portal has additional facilities like Technical Forums, News, Software Downloads,


Introduction: During crater formation a small amount of projectile material, generally less than 1 wt%, can be incorporated into impactites (impact melt rocks, suevites, impact glasses, and ejecta), resulting in a measurable geochemical signal. Such extraterrestrial (ET) components have, so far, been identified for just over ~40 out of the ~185 currently known terrestrial impact structures [1]. The vast majority of these structures are excavated in felsic targets (i.e., continental crust), making attempts for the geochemical identification of ET signatures rather straightforward. It remains, however, difficult to detect ET signals for the rare examples of impact craters formed in mafic lithologies. Tools for the identification of ET signatures generally take advantage of compositional differences between the impactor and the terrestrial target. For the most commonly applied tools, highly siderophile element abundances (e.g., platinum group elements [PGEs]), as well as Os/Os compositions, the differences between meteorites (i.e., chondrites and iron meteorites) and the terrestrial target diminish the more mafic the latter is, making it more difficult to distinguish between the indigeneous and the meteoritic component.

Ground tests to validate the models are described.


Developed countries have seen renewable energy as a key tool for emission reduction as well as reducing reliance on oil, gas, and coal. Renewable energy sources (RESs) and technologies have potential to provide solutions to the longstanding energy problems being faced by the developing countries. In the future competitive electricity market for India, it becomes very much important to give special consideration for development of RESs due to economic, environmental, and other social problems related with conventional generations. Solar energy can be an important part of India's plan not only to add new capacity but also to increase energy security and lead the massive market for renewable energy. The major problem with solar power generation (SPG) is high cost of renewable generation. The Indian government is providing a lot of subsidy in order to encourage renewable energy generations. This paper presents an approach for reduction in subsidy of SPG used as distributed generator in competitive power marke...


[2+2]-Cycloaddition of 'Maleic Isoimides' with Ketenes and Reactions of Spiro-b-lactams to Muconic and Tetramic Acids

The [2 + 2]-cycloaddition of iminolactones of type 2 ('maleic isoimides') with various ketenes affords spiro-b-lactams 4–6. These highly functionalized compounds react with CH3ONa giving ketoadipinic acid derivatives 12 and/or pyrrolidinediones 7, depending on the reaction temperature and the nature of substituents.


The spectrum of disorders attributable to primary aberrations of the developmental program should increase dramatically in the next decades, in concert with the continuing explosion of neurobiologic insights into normal brain development. Neurological disability is the most feared complication of pregnancy, labor and the neonatal period. The cause and effect relationship is often uncertain. The advent of 4D sonography and its application to study of fetal behavior have begun to provide insight into the structural and functional fetal brain development.


The Austin Chalk play, now inching its way across Texas, is a good working example of the difference between independents and majors, and a case study of the fight to get a small amount of oil out of the ground at a profit. Initial production averages 200 to 300 bpd but usually drop by 50% in 6 mo. Once the decline levels out, wells often produce at stripper rates for many years. Some 60 rigs are completing an average of 2 wells a month each along an ever lengthening strip of S.-central Texas. The play really started in the late 1920s but it fizzled, sputtered and all but died before finally igniting 2 yr ago. Austin Chalk is the main objective of this far-reaching program, which has accounted for no fewer than 300 wells either drilled or staked in Frio County alone since the beginning of 1975. This less than modest field is the beginning of a program which should account for hundreds of wells in an exploration and development program which will take years to complete, and which now involves no fewer than 20 independent operators.


Experimentally the transformation of N-alkylaniline to aniline is assumed to proceed by S N 2 reaction pathway. New concerted reaction pathway was proposed. These concerted reaction pathways were studied computationally and compared using different alkyl substituents (methyl and isopropyl). The computational calculation was carried out with Density Functional Theory using B3LYP (Becke-style 3-Parameter Density Functional Theory, that use Lee-Yang-Parr correlation functional) and 6-311++G (d, p) basis set. The reaction pathways were followed and verified with Intrinsic Reaction Coordinate (IRC). It was found that, in accordance with the experimental assumption, S N 2 reaction pathway was the choice of the transformation.

In the article, we have proposed regional environmental standards for heavy metals, oil and oil products in the main soils of southern Russia


AlGaN/GaN metal-semiconductor-metal inter-digitated varactors which are compatible with the standard HEMT process were fabricated. By analyzing equivalent circuit model,we concluded that the minimum capacitance of single finger depends on the sidewall capacitance. The depletion region beyond the gate gradually formed as the 2DEG channel was depleting, and a maximum width of depletion region of 4.65μm was obtained, with a width of 3μm and a bias voltage of 6V.


One of the most interesting topics in ecology systems is the stability of species.The delay population model for a single-species with harvesting was considered.Local stability was given by demark ramification.The curve of population which changes by time was given by numerical simulation,and adequate control of harvesting capacity causes the single-species in stability states.


A biological attack is the intentional release of a pathogen (diseasecausing agent) or biotoxin (poisonous substance produced by a living organism) against humans, plants, or animals. An attack against people could be used to cause illness, death, fear, societal disruption, and economic damage. An attack on agricultural plants and animals would primarily cause economic damage, loss of confidence in the food supply, and possible loss of life. It is useful to distinguish between two kinds of biological agents: 1.Transmissible agents that spread from person to person (e.g., smallpox, Ebola) or animal to animal (e.g., foot and mouth disease). 2.Agents that may cause adverse effects in exposed individuals but that do not make those individuals contagious to others (e.g., anthrax, botulinum toxin).


Underwater glider is one of the most practical and useful autonomous underwater vehicles. Power-driven propulsive machinery is not essential for underwater glider, so that it is applicable to long-term and wide-range operation. Furthermore, this silent and safe underwater vehicle can be maintained with relatively ease and is easy on ocean environment and many forms of life in the sea. An ocean-going underwater glider with independently controllable main wings for the use of ocean-environment monitoring has been developed. This paper deals with tank test and sea trials of the ocean-going underwater glider with independently controllable main wings, named `SOARER'. A simple cylindrical shape with NACA0030-shaped nose and tail cones and tapered main wings with NACA0009 section were adopted for improving the hydrodynamic performance. Main wings, upper rudder, diving rudder (elevator), movable balance weight, and sea-water pump for ballast tank can be controlled by on-board microcomputer system. Three axes acceleration, three axes angular velocity, depth and direction by magnetic compass during cruise can be measured for the use of feedback control. SOARER is navigated by dead reckoning under water, but accurate position can be obtained by using GPS when it is on the surface. These navigation data are transmitted from flight recorder to PC station by wireless LAN system when on the surface. The SOARER glider is equipped with the stand-alone ocean-environment monitoring profiler, `RINKO-Profiler' of JFE Advantech Co., Ltd. Its measuring items are depth, temperature, conductivity, salinity, dissolved oxygen, chlorophyll and turbidity.


Information security has been an area of research and teaching within various computing disciplines in higher education almost since the beginnings of modern computers. The need for security in computing curricula has steadily grown over this period. Recently, with an emerging global crisis, because of the limitations of security within the nascent information technology infrastructure, the field of "cybersecurity" is emerging with international interest and support. Recent evolution of cybersecurity shows that it has begun to take shape as a true academic perspective, as opposed to simply being a training domain for certain specialized jobs. This report starts from the premise that cybersecurity is a "meta-discipline." That is, cybersecurity is used as an aggregate label for a wide variety of similar disciplines, much in the same way that the terms "engineering" and "computing" are commonly used. Thus, cybersecurity should be formally interpreted as a meta-discipline with a variety of disciplinary variants, also characterized through a generic competency model. The intention is that this simple organizational concept will improve the clarity with which the field matures, resulting in improved standards and goals for many different types of cybersecurity programs.


Tree Resource Domestication (TRD) is recognised as a complex biological process but its value in the development of agriculture is yet to be substantially explored. The study makes use of tree utilization and conservation as an introduction to the concept of TRD that is built around ecosystems and genetics. A desire to use tree products on a sustainable level initiates the transfer of trees from their natural habitat to artificial environments. Tree resource growing in controlled environments exhibits profound changes in morphology and physiology leading to compact growth and higher productivity. These improvements in the biology of trees represent at the same time different Levels of Tree Development. Domestication as both ecological adaptation of trees to agricultural ecosystems and their genetic improvement provide clues into a development pattern in agriculture. These insights inform the proposal concerning Tree Resource Domestication in the development of agriculture.


In this paper, a novel control design based on a feedback linearization control (FLC) technique is developed for a Photovoltaic (PV) power optimizer implemented on a non-inverting buck-boost power converter. Unlike the classical local linearization techniques commonly used in the technical literature, this approach allows to obtain large-signal linear equations, by means of the feedback linearization of the non-linear terms. The non-linear model of the buck-boost converter operating in both buck and boost modes is presented, followed by the exact linearization and decoupling model using the FLC technique. From this linearized model, simple proportional and proportional-integral controllers are designed for the inner current and outer voltage control loops, respectively, in a cascaded control strategy. Simulation results demonstrate the effectiveness of this control technique, capable of regulating the PV voltage with consistent transient response, independent of the operating point of the PV source.


Cancer is the new epidemic of the 21st century and the second cause of death. In 2012, the annual incidence was 215,534 cases, while for 2020 it is expected to be 246,713 new cases, an increase of 12.6%. Australia is a country with a population of> 20 million inhabitants. Peter Mc Callum Cancer Center serves a population of more than 3 million inhabitants. This is a descriptive analysis of the most outstanding items in the daily organizational activity during the 2-month rotation at the PMCC, the only cancer hospital in the country and considered among the 10 best hospitals worldwide.


The documentation of adverse events rather than the legal implications of such events also deserves more emphasis. One of the purposes of a clinical trial is to compare adverse events during drug treatment with adverse events occurring coincidentally or due to the disease irrespective of treatment. The patient of course must be informed of all reasonable anxieties about side effects. However, it is not enough to say 'This treatment may make you sleepy or constipated.' It is better to say 'This treatment may make you sleepy or keep you awake; it may make you constipated or give you diarrhoea.' Discussion with the patient about serious and permanant side effects is a different matter. At £4 this is a good buy. It is not a substitute for a thorough understanding of the design of clinical trials, and ethical committees should not be persuaded that because an impressive and thorough protocol has been filled out the trial is necessarily scientifically valid.


It is important to use the right dressing for the wound type, as Rosie Pudner explains in the final part of her series.


Healthcare organisations and industries produces huge amount of data everyday. These vast information can be extracted and analysed to obtain patterns which can be used to forcast or predict the future events. Many healthcare organizations have already started collecting healthcare records to systematically use those data to identify patterns and improve health management of a particular population thereby providing improved care and reduced manual work and cost. This paper focuses on the survey of different dengue fever classification and study of a particular population where people are mostly diagnosed with dengue infection. It also discusses critical issues and challenges associated with data mining and healthcare in general. The research found a growing number of data mining applications, including analysis of health care centres for better health policy-making, detection of disease outbreaks. We have collected data from government hospitals. We have applied these data in our fuzzy logic and generated decision tree and compared the performance of other techniques.


While current research is sparse, the area of positive psychology is blossoming and represents a new and exciting field. Positive psychology is the "scientific study of the strengths and virtues that enable individuals and communities to thrive" (Seligman, 2007). Among others, positive psychology identifies empathy and open-mindedness as two strengths that help individuals to succeed. Empathy is a unique characteristic that encompasses the emotional and intuitive aspects of an individual. Empathy is understood as the capability to recognize or understand another's state of mind or emotion. More specifically, it is the process of observing something from another person's point of view, or putting oneself in another's shoes (Detert, Treviño, & Sweitzer, 2008). While empathy does not necessarily mean that the empathic individual experiences compassion for another individual, present research has shown that empathy has strong correlations with sympathetic emotions and other positive outcomes. Open-mindedness is understood to be the process of showing receptiveness to new or different ideas. Based on these definitions of empathy and open-mindedness, it is clear that the two are drastically similar. Both involve understanding another person's ideas or state of mind, and perhaps as a consequence, gaining some form of acceptance from this understanding. While interesting findings have been produced in relation to each of these traits, little information is available which describes how they interact with each other, or with other personality traits. The construct of the multicultural personality, first proposed by Ramirez (1991), was established to better understand the traits that allow people to effectively function in the multicultural setting. Since its initial introduction, various studies have been conducted, and most recently this construct has been adapted to fit within


Purpose The relationship between some macroeconomic variables and stock market returns still attracts the attention of researchers. Indeed, this interest lies in the fact the stock development enhances real economic growth. Within this context, the objective of this paper is to examine the Jordanian capital market (Amman Stock Exchange / ASE) in terms of the nexus between macroeconomic variables and the stock price index. Methodology To examine the relationship between real Gross Domestic Product (GDP) and consumer price index (CPI) and the ASE's market index, this paper covers the period 1980 – 2019, and uses time series techniques including stationarity test, lag length selection criteria, co-integration, Vector Error Correction Model (VECM), and some stability tests. Findings – In contrast to most of the published literature, the impact of real GDP on the ASE's market index and on its market capitalization is negative and significant. In addition, while the impact of consumer price index on the market index is not significant, its impact of market capitalization is negative and significant. Conclusion – Based on the estimated results, we argue that the ASE's performance does not reflect the performance of the national economy. On the contrary, the relationship is negative. In addition, we argue that the ASE's market index does not hedge investors against inflation. These results indicate that the ASE's market index should not be used as a proxy measure of the performance of the national economy.


The advantages of intramuscular excretion urography using hyaluronidase in children are emphasised, and a simple method giving satisfactory results described.


Determinations of the productive energy of poultry rations by the algebraic method of Fraps gave highly variable results which were 10–40% below values predicted from tables of energy production coefficients. Highly variable and low results were obtained whether groups or individual chicks were used for the determination. Results from a serial killing experiment suggested that assumptions made in the algebraic method were invalid.


The Grassland Earless Dragon 'Tympanocryptis pinguicolla' is a threatened species restricted to natural temperate grasslands of south-eastern Australia. The species has undergone significant decline across much of its range, with the last confirmed sighting in Victoria in 1969. We undertook targeted surveys in suitable habitat in western Victoria with the aim of detecting any remaining populations. Remote sensor cameras (Reconyx HC500) were deployed at a total of 14 sites across two seasons from October 2014 to February 2015, and from February to March 2016 (total of 3950 camera-trap-days). No Grassland Earless Dragons were detected. The absence of a confirmed sighting of the species in Victoria for 48 years suggests that there is a high likelihood that it may be extinct in Victoria. However, the lizard's small size and its cryptic behaviour mean that the possibility of locating a remnant population cannot be discounted entirely. Accordingly, Zoos Victoria is now working with the Corangamite Catchment Management Authority and local community to identify any potential sightings of the species by the public.


Based on the characteristics study of rutile ore which located in Shanxi Dai County, the author analyzed various factors that affected the exploitation and utilization of mineral deposit, and preliminary evaluated the prospect of mineral exploitation and utilization.


The recruitment of university researchers can be considered a multi-attribute group decision-making (MAGDM) problem. MAGDM is a familiar issue with uncertainty and fuzziness in the decision-making field. Generalized hesitation fuzzy numbers (GHFNs) as a new expanded form of hesitation fuzzy numbers (HFNs) can better express the uncertain information in MAGDM. The TODIM is a very classical and widely used method to deal with the MAGDM issue. In this paper, we integrate cumulative prospect theory (CPT) into TODIM to consider not only decision makers' subjective risk preferences but also their confidence level to obtain more reasonable choices under risk conditions. Therefore, we propose the GHF CPT-TODIM approach to tackle the MAGDM issue. Meanwhile, in the GHF environment, it is proposed to use the volatility of attribute information (entropy weighting method) to obtain the importance of attributes, obtain the unknown attribute weight, and enhance the rationality of weight information. Finally, the validity and usefulness of the technique are verified by applying the GHF CPT-TODIM technique to the recruitment of university researchers and comparing it with the existing GHF MAGDM method, which offers a new way to solve the MAGDM problem with GHFNs.


Introduction: Iron deficiency anemia (IDA) is a global health burden with an increasing prevalence in children and adult females. Traditionally, absolute iron deficiency has been based on low serum iron and ferritin. In recent years, the development of new automated hematologyanalyzers has paved the way for analysis of new parameters for mature red blood cells and reticulocytes in diagnosis of anemia. Materials and methods: Blood samples of adult females of reproductive age group (15-45 years) were collected and processed within 6 hours of collection. Based on hematological and biochemical findings, patients were segregated into four subgroups: Iron deficiency anemia (IDA, n = 40), Anemia of chronic disease (ACD, n=40), Latent iron deficiency (n=40) and Controls (n=40). Observations and results: The novel hematological parametersReticulocyte hemoglobin content (Ret-He), percentage of microcytic red blood cells (MicroR), hemoglobin content of erythrocytes (RBC-He) and percentage of hypochromic erythrocytes (HypoHe) had a statistically significant difference between the four groups (p < 0.05). The correlation between reticulocyte indices and iron parameters depicted that levels of Ret-He among all study participants (160) increased as the serum iron and serum ferritin increased indicating a significant positive correlation. Ret-He and RBC-He demonstrated better predictive power as per area under curve of ROC as compared to MicroR and HypoHe indices for latent anemia identification. Conclusion: The present study emphasized upon the importance of novel and cost effective routine new parameters in early and accurate diagnosis of IDA and ACD. Moreover Ret-He emerged as a sensitive and specific marker for diagnosis of latent iron deficiency.


AbstractReconstructive surgery for complex mandible defect with condyle is challenging for surgeons. Computer-aided planning and navigation is a useful adjunct for surgeons, which can improve visualization and orientation, insertion, mirroring, creation of planning models, and transformation of a surgical plan accurately. Here, we present a case of complex mandible defect reconstruction with computer-aided navigation and orthognathic surgery.


Resource allocation schemes for orthogonal frequency division multiple access- (OFDMA-) based cognitive radio (CR) networks that impose minimum and maximum rate constraints are considered. To demonstrate the practical application of such systems, we consider the transmission of scalable video sequences. An integer programming (IP) formulation of the problem is presented, which provides the optimal solution when solved using common discrete programming methods. Due to the computational complexity involved in such an approach and its unsuitability for dynamic cognitive radio environments, we propose to use the method of lift-and-project to obtain a stronger formulation for the resource allocation problem such that the integrality gap between the integer program and its linear relaxation is reduced. A simple branching operation is then performed that eliminates any noninteger values at the output of the linear program solvers. Simulation results demonstrate that this simple technique results in solutions very close to the optimum.


Risks exist in every form of construction project. The risks associated with construction projects are often diverse and varied and the management of these risks is nowadays considered compulsory in order to achieve project success. This paper analyses the diverse strategies of risk mitigation that have been employed in construction projects. These strategies are classified into analysed categories of procurement strategies. contingency and co-operative approach along with the utilisation of a designated risk manager. The analysis showed that in order to improve risk mitigation within the construction industry, there is a requirement tor an industry based standard. This standard will improve the efficiency and effectiveness of the risk mitigation response technique to risk management.


We develop a New-Open-Economy-Macro model in which Ricardian equivalence does not hold because of (i) distortionary labor and corporate income taxation; (ii) limited asset market participation; and (iii) because the overlapping-generations structure results in a disconnect between current and future generations. We consider a permanent increase in government debt following a cut in labor or corporate income taxes in a small and large open economy. We analyze the sensitivity of the results to the key structural parameters of the model and argue that under plausible assumptions there will be significant crowding-out effects associated with permanent increases in government debt.


One of Frank Boesch's best known papers is 'The strongest monotone degree condition for n‐connectedness of a graph' (Boesch, J Combinatorial Theory Ser B 16 (1974), 162–165.). In this article, we give a simple sufficient degree condition for a graph to be k‐edge‐connected, and also give the strongest monotone condition for a graph to be 2‐edge‐connected. © 2009 Wiley Periodicals, Inc.

The purpose of this case validation study was to examine the effects of Instrument-Assisted Soft Tissue Mobilization (IASTM) on the ankle. The patient population consisted of nine participants (2 females, 7 males, age = 16 ± 2 years) from a suburban high school in Illinois. Each patient completed an IASTM treatment program, incorporating the Graston Technique  (GT). The program was completed over a three-week period with 2 sessions occurring each week, for a total of 6 sessions. Data collection of ankle dorsiflexion range of motion (DFROM) occurred after the completion of the GT. This was assessed by performing the weight-bearing lunge test at the start and end of each treatment day. Results demonstrated that ankle DFROM did improve by the last session. The findings from this case validation study suggest that the use of GT is an effective intervention for increasing joint DFROM.


The recent advances in mobile technologies have resulted in Internet of Things (IoT)-enabled devices becoming more pervasive and integrated into our daily lives. The security challenges that need to be overcome mainly stem from the open nature of a wireless medium, such as a Wi-Fi network. An impersonation attack is an attack in which an adversary is disguised as a legitimate party in a system or communications protocol. The connected devices are pervasive, generating high-dimensional data on a large scale, which complicates simultaneous detections. Feature learning, however, can circumvent the potential problems that could be caused by the large-volume nature of network data. This paper thus proposes a novel deep-feature extraction and selection (D-FES), which combines stacked feature extraction and weighted feature selection. The stacked autoencoding is capable of providing representations that are more meaningful by reconstructing the relevant information from its raw inputs. We then combine this with modified weighted feature selection inspired by an existing shallow-structured machine learner. We finally demonstrate the ability of the condensed set of features to reduce the bias of a machine learner model as well as the computational complexity. Our experimental results on a well-referenced Wi-Fi network benchmark data set, namely, the Aegean Wi-Fi Intrusion data set, prove the usefulness and the utility of the proposed D-FES by achieving a detection accuracy of 99.918% and a false alarm rate of 0.012%, which is the most accurate detection of impersonation attacks reported in the literature.


This paper presents the efficient 2-D linear brake analysis model which can compensate the lateral leakage flux by changingng the airgap length and magneto-motive force(MMF). The linkage flux of the 2-D analysis is larger than that of 3-D analysis. This is caused by the assumption in 2-D analysis that geometric and physical values are constant along the perpendicular direction(z) to the analysis region. The equivalent MMF have been calculated from the linkage flux difference between the 2-D and 3-D analyses which are performed at zero velocity. The performances of the linear brake have been analyzed effectively by using the compensated 2-D models without using 3-D FEM.


Based on the observed wind speed,wind direction and temperature data from wind energy tower at Dagang in the western coast of the Bohai Sea from December of 2009 to November of 2010,the aerodynamic roughness Z0 around the wind energy tower was calculated using two methods: a wind-profile and a wind speed standard deviation. The results were analyzed and compared. The applicability of the wind speed standard deviation method and the effect of the inhomogeneous underlying surface on the roughness were discussed. The results show that the average roughnesses on three main wind directions are 0. 1319 m( north),0. 0386 m( south-east) and 0. 0182 m( south-west),respectively. The roughness calculated using the two methods could be similar if a strictly condition control is carried out. On the same direction,the seasonal differences of the roughness calculated by the two methods using 10-30 m meteorological data are not significant,while those using the 50-70 m data are significant. On the same layer,the differences of the roughness between different seasons are significant,which reflects the effect of the seasonal vegetation change on the roughness.


The purposes of this study were, first, to confirm inverse relationships between sex guilt and contraceptive use and attitudes and, second, to demonstrate that guilt regarding masturbation in comparison to sex guilt was a specific inhibitor of diaphragm use. In a sample of 186 single college women, sex guilt accounted for 28% of the variance in nine measures of contraceptive attitudes, thereby confirming the hypothesized inverse relationship. Users of safe, coitus‐independent, contraceptives scored lower on sex guilt than noncontraceptors. Moreover, the safe contraceptors, who used the pill or IUD, scored lower on sex guilt than women who relied on coitus‐dependent methods such as foam, suppositories, or condoms for contraception, which confirmed the second hypothesis. The third hypothesis was that masturbation guilt was inversely correlated with contraceptive attitudes. Including a measure of masturbation guilt along with sex guilt in a hierarchical multiple regression analysis revealed that masturbation...

Epoxy resin and polyethersulfone(PES) co-fixing system using 4,4'-diaminodiphenyl sulphone(DDS) as curing agent was studied to discuss the effects of curing process and formula.The phase separation and microstructure were investigated by differential scanning calorimetry(DSC) and scanning electron microscopy(SEM),which were controlled by the content of PES and curing process conditions.Results show that semi-interpenetrating networks(Semi-IPN) forms between epoxy resin and PES in which the glass-transition temperatures(t_g) of epoxy resin and PES is close by each other.Thus different phase structures can be obtained by controlling the reaction process and PES content.It is favorable to improve the impact property of PES-toughening epoxy resin with much of PES or higher curing temperature.


Research and development of fast,economic and effective controlling method and theory of landslide has always been the focus of anti-sliding projects for all the countries.In this research,a new kind of economic and suitable Ionic Soil Stabilizer(ISS for short) for improving the shear strength of sliding soil is studied.The sliding soil is treated by different matches of ISS and water at first,then is tested in the Atterberg limits test,direct shear test,routine consolidation test and free swell test.The results show that the plastic index decreases,and the cohesion increases and the void-ratio deflates and the free swell shrinks after mixing the ISS into the sliding soil of landslide.The mechanism is that the sliding soil that consists mainly of clay soil is mixed with ISS,which can replace the exchangeable cationic of clay surface,changes the pair-electricity layer of soil grain surface,reduces the thickness of adsorbed water,transforms the hydrophilic sliding soil to the hydrophobic and increases the shear strength of sliding soil by the function of physics and chemistry.
