EMEKA PROMISE UGWUNWOTTI, Ph.D DEPARTMENT OF BUSINESS EDUCATION ENUGU STATE UNIVERSITY OF SCIENCE AND TECHNOLOGY ABSTRACT This study empirically investigated the effect of Cooperative teaching Method on Senior Secondary School Students' Achievement and Retention in Financial Accounting in Enugu State. Four research questions and six hypotheses guided the study. Pretest-posttest non-randomized control group design was adopted for the study. The study was conducted in Agbani Education zone of Enugu State. The population for the study consisted of all co-educational senior secondary school one students who are offering Financial Accounting in Agbani Educational Zone of Enugu State numbering 300 whereas a sample of 165; 110 females and 55 males senior secondary school one students were drawn from (two intact classes). The cooperative group (experimental) consisted of 30 males and 85 females group totally 115 and 15 males and 30 females for controlled group. Techniques adopted for sampling was purposive multislage random sampling. Instrument used for data collection was Financial Accounting Achievement Test (FAAT) consisting of 60 item quwstions adopted from past WAEC and NECO question papers. The instrument was face and content validated by three experts. The instrument used was further tested on 20 senior secondary school one students similar to those used for the study in another Educational Zone. The researcher adopted the Kuder Richardson Formula (K-R20) in determining the pre-FAAT and post-FAAT hence yielded reliability coefficient of 0.68. Mean and standard deviation was used in answering research questions. Hypotheses were tested using Analysis of Covariance (ANCOVA) at 0.05 level of significance. The study revealed that the experimental group (cooperative group) achieved higher and retained more Financial Accounting than their counterparts in the control group. Also male and female students did not differ significantly in their achievement and retention in Financial Accounting. It was recommended that cooperative method should be used in teaching financial Accounting. Again, financial Accounting teachers should be encouraged to embark on regular training and retraining on the effective use of cooperative learning in the classroom.

Abstract: In this paper we study a nonparametric estimation problem for stochastic feedforward systems with nodes of type G/G/∞. We assume that we have observations of the external arrival and external departure processes of customers of the system, but no information about the movements of the indistinguishable customers in the network. Our aim is the construction of estimators for the characteristic functions and the densities of the service time distributions at the nodes as well as for the routing probabilities. Since the system is only partly observed we have to clarify first if the parameters are identifiable from the given data. The crucial point in our approach is the observation that in our stochastic networks under study the influence of the arrival processes on the departure processes can be described in a linear and time-invariant model. This makes it possible to apply cross-spectral techniques for multivariate point processes. The construction of the estimators is then based on smoothed periodograms. We prove asymptotic normality for the estimators. We present the statistical analysis for a tandem system of two nodes in full details and show afterwards how the results can be generalized to feedforward systems of three or more nodes and to systems with positive feedback probabilities at the nodes.


The purpose of this study is to investigate students' intention to continue using online learning platforms during face-to-face traditional classes in a way that is parallel to their usage during online virtual classes (during the pandemic). This investigation of students' intention is based on a conceptual model that uses newly used external factors in addition to the technology acceptance model (TAM) contrasts; hence, it takes into consideration users' satisfaction, the external factor of information richness (IR) and the quality of the educational system and information disseminated. The participants were 768 university students who have experienced the teaching environments of both traditional face-to-face classes and online classes during the pandemic. A structural equation modelling (SEM) test was conducted to analyse the independent variables, including the users' situation awareness (SA), perceived ease of use, perceived usefulness, satisfaction, IR, education system quality and information quality. An online questionnaire was used to explore students' perceptions of their intention to use online platforms accessibly in a face-to-face learning environment. The results showed that (a) students prefer online platforms that have a higher level of content richness, to be able to implement the three dimensions of users' situation awareness (perception, comprehension and projection); (b) there were significant effects of TAM constructs on students' satisfaction and acceptance; (c) students are in favour of using a learning platform that is characterised by a high level of educational system quality and information quality and (d) students with a higher level of satisfaction have a more positive attitude in their willingness to use the online learning system.

The concept of social mobility, as many other concepts, that underpin modern sociology is undergoing substantial evolution under the influence of change that occurs in modern societies often characterized as "fluid" and unstable. The mobility theory has been used by sociologists to diagnose the state of society, discover the directions to which it was heading. Early at the start of mobility studies one of the founders of social mobility theory called for a complex view of it, proposed to view as complex, inter-related moves of people, objects and ideas. P. Sorokin called for a study of mobility that incorporated not only human beings, but also artifacts and ideas. He regarded a complex view of mobility as opening a new perspective on change in modern societies. However, in the wake of the turbulent war and revolution ridden period the accent of mobility studies shifted, the rise of an industrial society placed emphasis on the study of workplace change and inter-class transition. Urbanization stressed geographical mobility from village to city. These ideas became central for many empirical studies, viewing modern society as a space of inter-class transition, primarily transitions into the growing middle class. The new hegemonic project led to a new emphasis on the reproduction and expansion of the middle class. The middle class society became a model for many developing countries. The ideology of mobility that inspired their many reformers and revolutionary leaders in the third world who often strove to adopt a policy of mobility at all costs. The policy led to serious complications, discord of social positions, tensions, political tension including as a result of the inability of the young reformist regimes to solve the problem of structural weaknesses of developing countries. The ideology and practice of mobility met with problems of inter-class barriers and their limited permeability as well as with the problem of culture that appeared to be less flexible than social positions. It is fair to assume that many of the negative phenomena in the Arab countries or other less fortunate parts of the world are the outcome of the failed mobility projects, dashed hopes of prosperity and better life for the masses. In early 21st century it is appropriate to discuss new tacks of mobility theory, marking a return to a multiple approach to mobility that would equally take into account its structural and subjective aspects, compare societal and individual perceptions of success, relate workplace stability, geographical, housing and other dimensions that make modern society so fluid.


Higher Education is facing the huge challenge of improving their productivity and competitiveness of the students, in addition to check what is its social function. Improving the quality of education and be more competent in the society is associated to promote alternative educational methodologies that allow connecting the curriculum with the reality, case of Service-Learning and mentoring. In this sense, the aim of this work was to explore the effectiveness of the Huelva Educa Program to improve the motivation, strategies of learning and social skills of mentors and school performance and school climate of "mentees". The sample was composed of 79 students from the University of Huelva, and 69 compulsory students selected through a sampling non-probability convenience. The outcome shows that university students who participated, they have significantly improved behaviors related to learning strategies (e.g., time and environment study, metacognitive self-regulation or regulation of the effort), and de compulsory students has increased the quantity and quality of their interactions, as well as improvement in school performance. These outcomes suggest the necessity of the implementation of such programs based on alternative methodologies within the process of change that is suffering Higher Education.


Onychomycoses, fungal nail infections, are responsible for 50% of all nail disorders affecting up to 18% of general population in some countries [1]. Nail lacquers (also transungual therapeutic systems) represent new drug forms specifically designed to enable longer release and sustained action of active principle into the infected nail plate [2]. We developed six formulations of nail lacquer containing 0,9% (w/v) fluconazole, Eudragit RS 100 and acetone. The formulations contain di-butyl phthalate, polyethylene glycol 400 or propylene glycol as plasticizers in two different concentrations. We characterized the developed formulations with regard to the drying time, fineness of formed film, fluconazole assay and viscosity. The drying time for the formulations with lower plasticizer content was 25 s, and for those with higher plasticizer content was 30 s. All developed formulations gave homogenous, smooth, glossy and transparent films. We developed simple derivative spectrophotometric method for fluconazole assay in all six formulations and the obtained results were in range of 97,5– 103,9% of the declared content. Viscosity was measured using rotating viscometer in accordance to Ph.Eur.6.0 [3]. The viscosity values were in range of 0,0055–0,0079 Pa×s, which are 50 times lower viscosity values in comparison to the cosmetic nail lacquers. Lower viscosities are preferred since they ensure better coverage and intimate contact with the nail plate leading to better therapeutic response. The obtained results comply with the standards for this type of preparations with regard to the drying time, film appearance, as well as good flow characteristics. The content of fluconazole is within usually prescribed limits of 100±5%. The results indicate good compatibility of the used ingredients in all six developed formulations.

Since classical computations cannot scale up to the computational power of quantum mechanics, how can we hope to verify the result of a quantum-enhanced computation? We present a new approach toward verification based on the ability to compute with encrypted data, while hiding the underlying function, through the detection of a cheating server. The core idea is to encode simple trap computations within a general computation that we run on a remote device in such a way that the computation is not affected, while revealing no information to the server. The correctness of the big computation is then tested via the verification of the trap computation.


By now it is fairly commonplace knowledge that Bertrand Russell, despite rumours to the contrary, was never a pacifist. No doubt he helped give currency to those rumours by sometimes calling himselfa pacifist, though at other times he vehemently denied ever being one.! Perhaps this confusion was due in part to the sort of ambivalence he expressed to Lady Ottoline Morrell early in the Great War: "I hardly know what I think. I don't think war always wrong.... I find I can't take Tolstoy's extreme position, and short of that it is so hard to know where to draw the line."2 Russell would probably have appreciated, and approved of, the sort of rigorous analysis that Martin Ceadel has recently applied to the use of the terms pacifist and pacifism. 3 Certainly, his careful definitions will be helpful to those who still conceive of pacifism as something one can be partly or mainly or even a little bit. Ceadel illustrates that pacifism is "an exacting personal faith" which cannot be, and never has been, successfully transformed into a political instrument. 4 Thus, we can safely say that Bertrand Russell was never a pacifist because at every stage of his long career, Russell's involvement in the peace movement was always intensely political. How then are we to describe Russell? Ceadel would call him a "pacificist", an unlovely though historically authentic title. s Since one can confidently predict that, however accurate, pacificism is too ugly to receive a decent hearing, perhaps Jo Vellacott provides the best starting point for describing Russell's place in the constellation of peacemakers. Vellacott calls him a "pragmatic pacifist" or one to whom "peace was of generally overriding importance ... and the route to obtaining or preserving it was negotiable."6 Russell described himself in very much the same way just after he had announced his support for the Allied war effort against Hitler. 7 The plea of pragmatism might help to explain Russell's running the gamut


During recent years, videogrametry has stood out as a measuring technique for biomechanical analysis. The DLT method (direct linear transformation) (Abdel-Aziz and Karara, 1971) is accepted and utilized in the majority of the kinematical analysis systems of human movement based on videogrametry. In order to be applied, the method requires the quantification of 11 parameters representing the structure of the colinearity matrix, which relates the object and image points. For this purpose, a certain number of markers called "control points", each one with known 3D location, are registered, measured and analyzed.


A simple equation suitable for predicting the growth rate of a vapor bubble in uniformly-superheated pure liquids and in binary solutions with a non-volatile solute was developed. The equation also improves on the popular pure-liquid bubble growth expression of Mikić et al. (1970) in that it is valid throughout the bubble growth history, i. e. in the surface-tension-, inertia-, and heat-transfer-controlled regimes, it accounts for bubble growth acceleration effects, and uses correctly-related and variable fluid properties. It was found to agree very well with experimental data for pure water and for aqueous NaCl solutions As the bubble growth in superheated solutions with a non-volatile solute was found to be quite insensitive to diffusion and non-equilibrium effects in a broad range of common solution properties, this equation is likely to be universally valid for many liquids and solutions.


3515 Background: The primary analysis of DREAM demonstrated that a maintenance therapy (MT) with bevacizumab (Bev) + EGFR TKI erlotinib (E) significantly improved progression-free survival (PFS) after a 1st-line Bev-based induction therapy (IT) in patients (pts) with unresectable mCRC. Methods: Pts were randomized to MT after an IT with FOLFOX-bev or XELOX-bev or FOLFIRI-bev between Bev alone (Bev 7.5 mg/kg q3w; arm A) or Bev+E (Bev 7.5 mg/kg q3w, E 150 mg/d ; arm B) until PD or unacceptable toxicity. Primary endpoint was PFS on MT. Secondary endpoints included PFS from inclusion, overall survival (OS) and safety. The impact of KRAS tumor status on treatment efficacy was evaluated in an exploratory analysis. Results: 700 pts were registered and 452 pts were randomized (228 in arm A, 224 in arm B). KRAS status was available for 413/452 (91%) pts. The median duration of MT was 3.6 m. Results for MT are presented below (Table). In the registered population, median OS was 24.9m (22.5 – 27.3). Conclusions: Mai...


Cooperative base-station (BS) signaling using MU-MIMO (Network MIMO) has received a great deal of attention given its ability to reduce inter-cell interference (ICI) and improve the system spectral efficiency. Indeed for a given number of antennas per BS, cooperative systems can have significant benefits over conventional cellular architectures. However cooperative signaling requires and uses more channel state information (CSI). This increases CSI signaling overhead, and can have a non-negligible effect on the system throughput. In fact once systems are compared while taking into account CSI overhead, the question of what system architecture is best becomes interesting and non-trivial. We provide one such alternative look at cooperative architectures. We show, despite prevailing views, that cellular architectures, using coordinated colocated antennas, can be quite attractive compared to Network MIMO.


Frequency diverse array (FDA) radar has been studied by many researchers due to the range-angle dependent beampattern which is different from the conventional phased array radar. However, the contribution of previous studies has received little attention within the circular frequency diverse array radar and no known empirical research has focused on investigating the three-dimensional (3D) parameter estimation (azimuth, elevation, and range). In this paper, we proposed a two-stage estimation algorithm for 3D parameter estimation of uniform circular frequency diverse array (UC-FDA) radar and firstly demonstrate the capability and performance of 3D parameter estimation. The first step of the two-stage estimation is the estimation of azimuth and elevation from the beamspace which is transformed from the element space by the beamformer. The second step is to substitute the angle obtained in the first step into the transmitting steering matrix for the range estimation. Cramér-Rao bound (CRB) that is used to evaluate the 3D parameter estimation performance is derived to compare. Theoretical analysis and numerical simulation demonstrate that the UC-FDA radar has superior 3D parameter estimation performance and the effectiveness of the proposed two-stage estimation algorithm. The research findings can contribute to a better 3D localization method and represent an additional step towards developing multi-dimensional localization and interference suppression for UC-FDA radar.


This study presents the temperature effect and a performance comparison of mono-crystalline Silicon (mc-Si), poly-crystalline Silicon (pc-Si), amorphous Silicon (a-Si) and Cupper Indium Gallium di-selenide (CIGS) photovoltaic technologies under Climate Conditions of Baghdad city. Temperature influence on the solar modules electric output parameters was investigated experimentally and their temperature coefficients was calculated. These temperature coefficients are important for all systems design and sizing. The experimental results revealed that the pc-Si module showed a decrease in open circuit voltage by -0.0912V/oC while mc-Si and a-Si had nearly -0.07V/oC and the CIGS has -0.0123V/oC. The results showed a slightly increase in short circuit current with temperature increasing about 0.3mA/oC ,4.4mA/oC and 0.9mA/oC for mc-Si , pc-Si and both a-Si and CIGS. The mc-Si had the largest drop in output power about -0.1353W/oC while -0.0915, -0.0114 and -0.0276 W/oC for pc-Si, aSi and CIGS respectively. The amorphous silicon is the more suitable module for high operation temperature but it has the lowest conversion efficiency between the tested modules.

Polymer thick films compatible with a thermoforming process are the key components to realize the next generation of human–machine interface and lighting with a 3D custom shape through an in-mold process. The purpose of this study is to demonstrate that a tailored combination of commercial pastes can offer the manufacturer more freedom in developing smart electronic devices. A four-point probe instrument was used to measure the resistivity of the printed circuit. We used the same formed printed sample to estimate the level of elongation under the thermoforming process due to the all-in-one screen design developed for the study. The important objective of this work was to form a paste which should withstand such operations without losing physical properties such as conductivity or adhesion or getting lines cracked.


In this paper we propose an adaptive interval valued fuzzy controller for high performance direct vector-controlled induction motor drive. Interval valued controller compared with type-1 fuzzy controller has the advantage that it can take into account the linguistic uncertainties present in the rules of the estimated models. The proposed control framework consists of a mixture of two controllers: an interval valued fuzzy controller and a supervisory controller. The supervisory controller is used when the system starts to become unstable. The free parameters for the proposed controller are changed according to some learning rules based on Lyapunov stability. Simulation results on an induction motor show the effectiveness of the introduced method.


This paper is concerned with monotone iterative methods for numerical solutions of a class of nonlinear fourth-order elliptic boundary value problems in a two-dimensional domain. The boundary value problem is discretized by the finite difference method, and two iterative processes, called block Jacobi and block Gauss-Seidel monotone iterations, are presented for the computation of solutions of the finite difference system using either an upper solution or a lower solution as the initial iteration. It is shown that the sequence of iterations converges monotonically to a maximal solution or a minimal solution if the nonlinear function is quasi-monotone nondecreasing. A sufficient condition is given to ensure that the maximal and minimal solutions coincide and their common value is the unique solution of the finite difference system. Similar results are obtained for quasi-monotone nonincreasing functions. An analytical comparison relation between the block Jacobi and block Gauss--Seidel monotone iterations is obtained. It is also shown that the finite difference solution converges to the continuous solution as the mesh size tends to zero. Numerical results by the block monotone iterative schemes are given for two model problems and are compared with the known analytical solutions for accuracy. Also compared are the rates of convergence of the two types of block monotone iterations as well as similar types of pointwise monotone iterations.

Transtibial and transfemoral amputations are the most common amputations in the world, loss of lower extremity result in impaired function extremities and also body balance. A prosthesis is a medical device designed to replace a specific body part to restore function to a body part lost due to an accident or disease. Most doctors strongly recommend the use of a prosthesis so that patients can return to normal activities after undergoing an amputation. Besides functioning to support beauty, the use of prostheses is also to restore the quality of life of prosthetic users, the issue of metabolic energy consumption when walking is also very important in designing transtibial bionic prosthesis because it involves the comfort of the user transtibial prosthesis. Most of the existing transtibial prosthesis products in Indonesia are conventional passive transtibial foot products, and passive prosthesis users show a limp or asymmetrical gait pattern so that conventional passive prosthesis users experience discomfort when walking in the form of pain in the amputated leg and normal foot, which can cause secondary musculoskeletal injuries such as joint disorders. Passive prostheses cannot generate propulsive force during push-off phase (terminal stance and preswing) of the human gait cycle. The use of passive prostheses can also consume 20-30% more metabolic energy while walking so that it can cause fatigue for the user. Transtibial bionic prosthesis research is growing, transtibial bionic prosthesis can overcome the weakness of passive prosthesis because it can produce push-off during gait cycle and several researchers have shown that bionic prostheses are capable of mimicking the human gait, as well as improve the  performance in a more natural gait and normal walking. This study aims to study the existing transtibial bionic prosthesis by comparing between 6 existing designs of powered ankle or transtibial bionic prosthesis that have been published in several publications. The discussion focuses on the design and mechanical systems, actuators related to the selection of motors and drive mechanisms as well as power transmission from actuators to moving components.


[reaction: see text] A remarkable exo-facial template effect exercised by a 2, 3-O-isopropylidene protective group is the key for the entire 2, 3-trans stereoselectivity observed in the allylsilane addition promoted by BF(3).OEt(2) to 2,3-O-isopropylidene-protected pyrrolidines.


ABSTRACT.This paper investigates the relationship between stock prices, exchange rate and demand for money in India during the period of post liberalization in India. The objective of the paper is two-fold. First, the study aims to shed light on the co-integrating properties of different monetary aggregates, stock prices, exchange rate, interest rate, economic activity, and inflation in India. Specifically, the purpose is to determine whether there is a stationary long run relationship between demand for different monetary aggregates and their determinants. Secondly, the study investigates the stability of the long run money demand function with its determinants. For the analysis, monthly data from 1996:1 to 2010:8 is used. The study employs the Johansen and Juselius Co-integration (1990) approach for checking the long run integration among the variables along with VECM model. Further, Granger Causality test is carried out. The test results discloses the presence of more than two co-integrating vector for each money demand specification. The long run elasticity of demand for money reveals that money demand function is sensitive to inflation, stock prices and economic activity. Unidirectional causality is reported from stock prices and exchange rate to demand for money function.JEL Classification: C32, E41, E44, E51Keywords: demand for money, stock prices, monetary aggregates, exchange rate, co-integration, Granger Causality(ProQuest: ... denotes formulae omitted.)1. IntroductionDemand for money determination is one of the major issues in the field of monetary economics literature. The issue of demand for money has been the subject of vast empirical and theoretical investigation over the couple of decades by researchers. There are several motivations for this line of enquiry. Arguably, demand for money in simple terms is the people's desire to hold money. Demand for money has been studied in different dimensions in the past literature like determinants of demand for money and stability of demand for money over the period of time. There are different determinants identified by different economist which affects the demand for money. The determinants are output, interest rate, exchange rate, stock prices, and inflation etc. which can significantly affect the demand for money. Further the stability of demand for money implies that the quantity of money can be predictable related to various macroeconomic variables Friedman (1987). The stability of demand for money over the period is crucial for efficient monetary policy transmission. In the past various studies tried to identify the suitable determinants of demand for money and stability of demand for money which can be stable over the period for particular economy. In this context the present study examines the stable long run relationship between money demand, stock prices and exchange rate in India. Because, a consistent stable relationship between money demand and its determinants like stock prices and exchange rate is prerequisite for monitoring and targeting of monetary aggregates. The Central Bank has control over the money balance, which can affect the macroeconomic policy. The success of the monetary policy depends on whether there exists a stable relationship between money demand and its determinants.The literature on demand for money has been quite extensive both theoretically and empirically. From the theoretical perspective the early classical economist Fisher (1911) stated that real income determines the real demand for money. Theoretically high income of the people increases the transaction demand for money. Further, Keynes has assumed that there are different motives such as transaction, precautionary and speculative demand for money. According to this theory income and interest rate play a significant role for determination of demand for money. Income determines the transaction demand and interest rate determines the speculative demand for money. …


The demands from modern society to medical talent are not only outstanding records but also abilities of other sides,for instance,spiritual mood,ability of innovation,arrangement of conforming variation and so on.The talent of the 21th centruy should adjust their systems of personality,and possess "spiritual flow"and "ability of transferring emotions",so that they have larger space to develop,breathe and also realive the value of themselves.There are severe challenges for modern education.It puts forward regenerative and further demand for training medical talent.


Programs to reduce unaccounted for water (UFW) have been frustrating experiences in many Bank-supported oeprations. Lack of accountability and managerial incentives to deal with the problem have been offered as the main factor to explain this experience and will not be discussed further in this report. Nonetheless, a lack of clear understanding of the causes of UFW and of the costs and benefits that can derive from UFW reduction also contributes to unsuccessful water reduction programs. The purpose of this note is to document these causes and potential payoffs from UFW reduction in the light of two successful experiences and to draw some lessons from them. UFW is defined as the difference between water delivered to the distribution system and water sold. Therefore, the reliability of UFW estimates hinges on both production and consumption being fully and reliably metered. Metering is a major deficiency for most utilities in developing countries. UFW includes two basic components: physical and commercial losses. Physical losses include water lost from pipe leaks in systems, in house connections, and from overflows in distribution tanks. Commercial losses represent water used but not paid for. They stem from the unauthorized use of water (illegal connections), from faulty meters that inaccurately register consumption, and from tampering with the often inadequate controls of the commercial system (meter reading and maintenance, billing and collection); this results in fewer consumers and less consumption acknowledged as well as less water sold.


Functionally graded materials (FGMs) are multi-phase composites with gradual spatial variations of constituents. The compositional transitions in the FGMs are classified into two manners such as continuous gradient manners and stepwise manners. In this study, zirconia (ZrO2)/ 304 stainless steel (SUS304) FGMs with continuous gradient manners were fabricated by a combination of centrifugal slurry methods and spark plasma sintering (SPS). A variety of continuous gradient patterns were achieved by controlling the amount of dispersant such as ammonium polycarboxylic acid (PCA) in the slurry. With an increase in the amount of PCA, the gradient patterns in the FGMs changed from ceramic (ZrO2)-rich to metal (SUS304)-rich ones. According to Stokes sedimentation velocity simulations, the sedimentation velocity of SUS304 particles is higher than that of ZrO2 particles. With an increasing amount of PCA, the sedimentation velocity of the particles decreases. Cyclic thermal shock test results demonstrated that FGMs with metal (SUS304)-rich continuous gradient patterns showed the highest resistance among the samples of FGMs, 5-layered materials and ZrO2 single materials.


Waning immunity after vaccination justifies the need for additional effective COVID‐19 treatments. Immunomodulation of local immune response at the oropharyngeal mucosa could hypothetically activate mucosal immunity, which can prevent SARS‐CoV‐2 main immune evasion mechanisms in early stages of the disease and send an effective warning to other components of immune system. Olive polyphenols are biologically active compounds with immunomodulatory activity. There are previous studies based on immunomodulation with olive polyphenols and respiratory infections using an enteral route, which point to potential effects on time to resolution of symptoms. The investigators sought to determine whether participants following immunomodulation with tiny quantities of high polyphenolic olive oil administered through an oromucosal route could have a better outcome in COVID‐19.


Background The "secondary brain insult" including ischemia, hypoxia and edema after primary traumatic brain injury (TBI) may deteriorate the brain damages and greatly influence the prognosis. As a selective vulnerable region, the hippocampus is especially sensitive to ischemia, hypoxia or edema and yields irreversible sequelae. Aquaporin 1 (AQP1) has been reported to be related to cerebral edema, but the expression and role of AQP1 in hippocampal edema after TBI have seldomly been investigated. In this study, we established BALB/c mouse closed craniocerebral injury models and investigated the changes of AQP1 expression in hippocampus of mouse models after TBI, thereby discussing its effects on relevant pathophysiological processes.  Methods Seventy-five BALB/c mice were used to establish experimental closed TBI models with a free-falling weight drop device, and the equal numbers of mice were subject to sham operation and categorized as sham group. The neurological function of each mouse in either TBI group or sham group was scored at different time points (1, 6, 24 and 72 h) after TBI or sham operation, and brain edema formation of the mice in both groups was also evaluated accordingly at 6, 24 and 72 h. The apoptotic hippocampal cells were stained in situ and detected using TdT-mediated dUTP-biotin nick end labeling (TUNEL) method at different time points (6, 24 and 72 h), then AQP1 expression in hippocampus was also correspondingly detected using immunohistochemistry and Western blotting. All the data were finally compared with those in sham operation group and analyzed.  Results Experimental TBI models were successfully established and confirmed by the neurological function score and hippocampal edema evaluation. Six hours after craniocerebral injury, the apoptotic cells increased significantly in the hippocampus of mice in TBI group compared with those in sham group [(44.26 ± 15.18)% vs (8.61 ± 8.25)% , t = - 9.676, P = 0.002]. The apoptotic rate increased gradually with the prolonging of time and was highest at 72 h [(61.62 ± 26.55)% vs (10.17 ± 6.08)%; t = - 5.018, P = 0.015]. Determined at different time points by immunohistochemistry and Western blotting assays, the AQP1 expression in mouse hippocampus was constantly higher in TBI group than in sham group ( P < 0.05), and reached the peak at 24 h (0.69 ± 0.32 vs 0.15 ± 0.07, t = - 4.335, P = 0.023 and 0.46 ± 0.19 vs 0.14 ± 0.04, t = - 4.113, P = 0.004, respectively).  Conclusions The up-regulation of AQP1 in mouse hippocampus after TBI perhaps participates in edema formation and delayed apoptosis of hippocampus, and AQP1 may be a new therapeutic target to protect hippocampus from secondary injury after TBI. doi: 10.3969/j.issn.1672-6731.2014.03.016


The customer service agent of the government service hotline has been providing great help to people's daily lives. To facilitate further work analysis, after the customer service agent completes the dialogue consultation each time, it is necessary to select the related knowledge point for summarizing and record the dialogue from the large-scale knowledge point base according to the current consultation dialogue content. However, this work adds a great burden to the customer service staff. In order to reduce the workload of customer service agents in selecting knowledge points, we explore several approaches based on the consultation dialogue in the customer service scenario, e.g., the text classification model based on BERT, the word vector convolutional neural network classification model, and the pseudo-siamese neural network model. Extensive experiments demonstrated that our methods perform well in terms of accuracy and scalability, and further we designed an efficient and well-structured API module which is easily integrated into service application.


A temporal nodes Bayesian network (TNBN) is an alternative graphical representation of temporal probabilistic information.The temporal functional dependency is an important data dependencyin temporal relational databases. In this paper temporal data dependencies are extended into delayed conditions, called asynchronous dependencies. The purpose of this paper is to set up a connection between these asynchronous data dependencies and TNBNs. We show that we can obtain the maximum conditionalin dependencies implied by given temporal functional dependencies. Furthermore, we propose an approach to construct a TNBN from a set of temporal functional dependencies.

In the context of human motion analysis and human-centered computational sensing, this work presents a methodology for the investigation of the relations among actions of a set of (Modern Greek) motion verbs. The actions denoted by these verbs fall in the motion categories of pushing, pulling, hitting, and beating. Motion data were collected with motion capture technology, and measures of correlation and distance are used to identify existing relations among actions. Finally, hierarchical clustering analysis was applied to identify groups of actions. The results are in line with a semantic categorization of the corresponding verbs. The overall experimental procedure and data analysis indicate that the employed methodology could be useful in promising applications of motion recognition or motion clustering, aiming at the identification of related captured actions.


Energy systems with high shares of variable renewable power generation have an increased need for power system flexibility. In parallel, renewable energy has an important role in circular economy as circular activities such as material processing consumes power and heat. This paper examines if harnessing flexibility from circular economy processes related to upgrading of side and waste material flows increase the value of a renewable energy system. Analysis is conducted on a selected case region as the availability of both circular processes and renewable energies are region-specific depending of the local characteristics. The potential of circular economy as a demand source for abundant variable renewable energy supply is compared to a highly electrified transportation sector and to power-to-heat conversion in addition to the baseline scenario. The analysis is performed with a developed mixed integer linear programming (MILP) model in which energy system operation and selected circular material flows are simultaneously optimized. Keywords—circular economy, wind power, variability, flexibility

Counterfeit integrated circuits (ICs) have become a significant security concern in the semiconductor industry as a result of the increasingly complex and distributed nature of the supply chain. These counterfeit chips may result in performance degradation, profit reduction, and reputation risk for the manufacturer. Therefore, developing effective countermeasures against such malpractices is becoming severely crucial. Physical unclonable function (PUF)-based authentication methods have the potential to mitigate these challenges. However, PUF-based solutions are restrained by several factors, such as additional design efforts and significant area/power overhead, struggle to maintain and update challenge–response pairs (CRPs) database, and the vulnerability to machine learning (ML) attacks. In this article, we address these challenges by developing a novel database-free and enrolment-free hardware authentication approaches, i.e., a digital watermark metric for ICs. To enable efficient database-free hardware integrity verification without enrolment, first, we transform the intrinsic variations in circuit parameters, e.g., boundary scan chain (BSC) path delays in the joint test action group (JTAG) chain into robust digital signatures. Then, we perform statistical analysis on a small pilot unit of authentic chips to create a robust watermark for a complete batch of chips, which jointly captures the characteristics of the physical layout, the manufacturing process, and the foundry. The increasing complexity in the current state-of-the-art designs makes it extremely hard for an adversary to perfectly clone such statistical characterization of circuit parameters using counterfeit or compromised hardware. Besides, the proposed approach requires no additional design or hardware overhead in IC design since it utilizes an embedded structure, which inherently exists within the chips. It also obviates the design house from characterizing each manufactured chip instance, reducing overall testing cost. A path-delay measurement method at a high resolution based on clock phase sweep is introduced to measure the delay values effectively. The proposed intrinsic identifier-based authentication approach is validated by performing emulation on FPGAs and also by conducting physical measurements on custom-made printed circuit boards (PCBs). The reliability of the generated watermarks is evaluated with environmental temperature fluctuations and the aging effect.


We consider a facility-location problem that abstracts settings where the cost of serving the clients assigned to a facility is incurred by the facility. Formally, we consider the minimum-load k-facility location (MLkFL) problem, which is defined as follows. We have a set F of facilities, a set C of clients, and an integer k≥ 0. Assigning client j to a facility f incurs a connection cost d(f,j). The goal is to open a set F⊆ F of k facilities and assign each client j to a facility f(j)∈ F so as to minimize maxf∈ F∑ j∈ C:f(j)=fd(f,j); we call ∑ j∈ C:f(j)=fd(f,j) the load of facility f. This problem was studied under the name of min-max star cover in References [3, 7], who (among other results) gave bicriteria approximation algorithms for MLkFL for when F=C. MLk FL is rather poorly understood, and only an O(k)-approximation is currently known for MLkFL, even for line metrics. Our main result is the first polytime approximation scheme (PTAS) for MLkFL on line metrics (note that no non-trivial true approximation of any kind was known for this metric). Complementing this, we prove that MLkFL is strongly NP-hard on line metrics. We also devise a quasi-PTAS for MLkFL on tree metrics. MLkFL turns out to be surprisingly challenging even on line metrics and resilient to attack by a variety of techniques that have been successfully applied to facility-location problems. For instance, we show that (a) even a configuration-style LP-relaxation has a bad integrality gap and (b) a multi-swap k-median style local-search heuristic has a bad locality gap. Thus, we need to devise various novel techniques to attack MLkFL. Our PTAS for line metrics consists of two main ingredients. First, we prove that there always exists a near-optimal solution possessing some nice structural properties. A novel aspect of this proof is that we first move to a mixed-integer LP (MILP) encoding of the problem and argue that a MILP-solution minimizing a certain potential function possesses the desired structure and then use a rounding algorithm for the generalized-assignment problem to "transfer" this structure to the rounded integer solution. Complementing this, we show that these structural properties enable one to find such a structured solution via dynamic programming.

Current recommendation systems usually use image as a type of side information to enhance recommendation systems. However, there are few models to analyze and apply the effectiveness of different categories of images. In order to effectively combine multi-category image information in the recommendation system, we propose a novel deep network model with different categories of images as side information for recommendation, in which we use convolutional attention to analyze the importance of images within different image categories. The convolutional layers of the attention module are used to evaluate the user's visual preferences for images in different categories. The prediction model uses the cosine similarity of user factors and restaurant factors incorporating visual information. Visual features of the restaurants are extracted from multi-category images by a pre-trained neural network. We apply our model to two real-world restaurant recommendation data sets. Experimental results show that the performance of our model is better than models without or with only one category visual information.


The article presents the results of studies of energy, environmental and fuel efficiency indicators of a passenger car with a gasoline injection system. The engine is equipped with a device additionally supplying liquefied petroleum gas (LPG) and it has an ignition timing variator (ITV). As a result of research, an improvement in the fuel efficiency of a car in thermal equivalent was found when the engine was running on LPG and a slight increase in energy performance was observed. Emissions of pollutants with exhaust gases change in different ways: emissions of carbon monoxide practically do not change, emissions of hydrocarbons and nitrogen oxides are growing, carbon dioxide emissions from LPG operation are reduced, socio-economic damage when the engine is running on LPG is also reduced.


The structural properties of services have a major role in achieving the SOA capabilities. It is important to validate the service design artifacts. Several metrics are proposed to quantify SOA service design. An enterprise has to focus on service design aspects to achieve the IT-based capabilities in the initial stages of SOA adoption. The existing SOA maturity models provide minimal guidance on design time validation. Therefore, this paper presents a list of structural attributes of service interface that influences the SOA capabilities defined in Welke's SOA maturity model. The existing SOA service design metrics are analyzed to identify the structural properties associated with infrastructure efficiency, service reuse, and composition. The critical attributes are presented to guide the service designers. All these attributes influence the SOA capabilities; however, the degree to which they relate to each capability varies. The future wok includes the metric definition for these attributes to support the maturity assessment of SOA methods.


Abstract This paper argues that delivering free services is driven by a combination of motivations and explains how policy makers or other principals can exploit them to deal with underproduction of free services. We identify intrinsic motivation, respect and gratitude as main examples of underlying motivations. What is essential for free services is that there is considerable heterogeneity in how these motivations are valued across the population. We show how a menu of (monetary and non-monetary) rewards can easily outperform simple compensation approaches since it allows for self-selection and caters for the heterogeneity. As the leading example, we illustrate how a menu can improve the academic referee process. The menu idea can be used in a large set of settings and is potentially very fruitful.


Diabetes Mellitus, especially type II Diabetes Mellitus (T2DM), is one of diseases being important of lifestyle modification as a medical therapy. Among them, nutrition education as well as exercise is a main strategy to control fasting blood glucose. The aim of this research is to determine appropriate time for both interventions according to blood glucose level and BMI of patients with T2DM. We searched DBpia and KISS from 2015 to 2016, and collected 109 articles. From this, we selected 30 articles written Korean hospitals or public health centers. All articles had mean values of fasting blood glucose (FBG) concentration (mg/dl) and BMI (kg/m2) measured at pre and post exercise or nutrition education at least four weeks and over twelve weeks follow‐up. The collected articles were divided 4 groups depending on exercise or nutrition education treatment besides of drug and diet therapy. Three articles reported no treatment was considered as control groups. Data were extracted in IBM SPSS Statistics Data Editor. The results are as follows; total number of subjects was 870 persons. Average age of subjects was 55.4(+/6.7) years old and the range was 52.1~58.2 years old. Their average BMI was 24.6(+/_0.7) kg/m2 and the range was 24.3~25.5 kg/m2. And average FBG concentration was 157.3(+/_30.7) mg/dl and range was 118.0~228.9 mg/dl. After treatment, FBG and BMI of subjects showed no significant differences. However there was statistically significant difference in the mean difference of FBG concentrations between pre‐ and post‐ nutrition education intervention (p<.009). Interestingly higher BMI level at initial was, the more exercise tended to be tried (p<.051). While the lower FBG concentration were, the more nutrition education were applied (p<.0001). Conclusively the appropriate timing might be needed to intervene to T2DM patients with exercise or nutrition education treatments depending on subject's FBG and BMI conditions.


Prior to the congressional vote, organized labor threatened to punish legislators who voted for NAFTA. Building on work by Engel and Jackson, I explore whether or not organized labor made good on its threat by reducing campaign contributions to Democratic House members who voted Yes. I postulate contribution functions for both Democrats and Republicans, with preNAFTA vote contributions on the horizontal axis and post-NAFTA vote contributions on the vertical axis. For members of both parties, I find that a Yes vote on NAFTA results in a change in the contribution function, which is a combination of a downward proportional shift and a downward parallel shift. According to National Public Radio's Morning Edition, April 12, 2000, George Meany, ex-President of the AFL-CIO, instructed unionists on their lobbying visits to legislators to impress upon them: "We never threaten, we never beg, and we never forget." ∗ This project would not have been possible without the support and guidance of my advisor, Edward Tower. I would also like to thank the following people for their comments and suggestions: Merlise Clyde, Edward Phillips, Karen Phillips, and Annemie Berding.

Abstract A study on smart seats for railroad vehicles was conducted using piezoelectric (PZT) sensors. For this purpose, the concept of passenger friendly smart seats was defined, and a PZT sensor was selected as the optimum sensor based on this concept. Using PZT sensors, simulation tests were performed using a sub-scale model railroad vehicle. In these tests, the main functions of the smart seats were extracted and simplified to improve the effectiveness of the simulation tests. Based on the test results, the system for smart seats proposed in this paper was successfully verified using PZT sensors and the dedicated operation software for the system. This paper will contribute to the improvement of services in high-speed rail systems through advances in ticket checking tasks.

Models of stellar structure and evolution are an indispensable tool in astrophysics, yet they are known to incorrectly reproduce the outer convective layers of stars. In the first paper of this series, we presented a novel procedure to include the mean structure of 3D hydrodynamical simulations on-the-fly in stellar models, and found it to significantly improve the outer stratification and oscillation frequencies of a standard solar model. In this work, we extend the analysis of the method; specifically how the transition point between envelope and interior affects the models. We confirm the versatility of our method by successfully repeating the entire procedure for a different grid of 3D hydrosimulations. Furthermore, the applicability of the procedure was investigated across the HR diagram and an accuracy comparable to the solar case was found. Moreover, we explored the implications on stellar evolution and find that the red-giant branch is shifted about $40\, \mathrm{K}$ to higher effective temperatures. Finally, we present for the first time an asteroseismic analysis based on stellar models fully utilizing the stratification of 3D simulations on-the-fly. These new models significantly reduce the asteroseismic surface term for the two selected stars in the Kepler field. We extend the analysis to red giants and characterize the shape of the surface effect in this regime. Lastly, we stress that the interpolation required by our method would benefit from new 3D simulations, resulting in a finer sampling of the grid.


Papparella A et al. Laparoscopy in the Diagnosis ... Eur J Pediatr Surg 2011; 21: 203 – 204 Introduction ▼ Splenogonadal fusion is a rare congenital anomaly involving abnormal fusion between the spleen and the gonad. The fusion can be continuous or discontinuous, depending on the presence or absence of a structural connection between the regular spleen and ectopic splenic tissue attached to the gonad. Clinical presentation is usually as a testicular mass, and diagnosis is in most cases accidental; sometimes other congenital abnormalities are present [1 – 3] . We report the case of a child with a continuous type splenogonadal fusion which manifested itself as a testicular mass. The diagnosis and surgical treatment were suggested by diagnostic laparoscopy.

Background In recent years, due to academic pressure, changes in interpersonal relationships, and living environments, the mental health problems of college students have gradually become prominent, with obsessive-compulsive disorder (OCD) becoming an indispensable part. Patients with obsessive-compulsive disorder often suffer from recurring obsessive-compulsive beliefs and behaviors, seriously affecting their daily lives and academic performance. Therefore, seeking effective intervention methods is crucial. Subjects and Methods The experiment selected 60 students with obsessive-compulsive disorder from a particular school and randomly divided them into an experimental group and a control group, with 30 students in each group. The experimental group received practical teaching of flower arrangement art and acceptance commitment therapy (ACT). The control group only used traditional psychological counseling methods. The experimental period is six months, and the data is statistically processed using SPSS 24.0 and Excel. Results After a 6-month intervention, the obsessive-compulsive symptoms in the experimental group were significantly reduced, with a total effective rate of 90%, while the effective rate in the control group was 60%. In addition, the experimental group's self-efficacy, emotional regulation ability, and quality of life also significantly improved. Conclusions The combination of flower arrangement art practice teaching and acceptance commitment therapy has shown sound intervention effects in treating obsessive-compulsive disorder college students. This combined treatment method can not only effectively alleviate obsessive-compulsive symptoms but also enhance the patient's psychological resilience and self-management ability. Promoting this method has significant practical value in future mental health work.

This paper argues that, despite government support in financial and contractual matters, ongoing problems of retention of Native‐speaking English Teachers (NETs) in Hong Kong stem, in part, from problems of cross‐cultural adjustment. The paper reports a small‐scale qualitative investigation into the experiences of NETS in Hong Kong and finds problems of cross‐cultural adjustment of the NETs themselves, the host schools and the government's induction practices. The paper reports a diversity of problems in cross‐cultural adjustment and a variety of ways in which NETs handled them. The argument is made for increased and differentiated attention to be given to the cross‐cultural adjustment of NETs, for greater social networking and for reducing the isolation and cross‐cultural stresses that they experience. It is suggested that this might attenuate the problem of high NET turnover in Hong Kong.


The factor that makes enzyme biocatalysts for organic synthesis both fascinating and challenging from a scientific standpoint is the field's higher interdisciplinarity, and which necessitates expertise from a wide range of disciplines, including microbiology, organic synthesis, molecular biology, genetics, and reaction engineering. Enzymes can now carry out a wide variety of organic reactions, including hydrolytic reactions, redox reactions, and C-C bond formations, with higher performance. Enzyme catalysis has also evolved into a widely used manufacturing technology in the chemical industry, especially in the fields of fine organic chemicals and pharmaceuticals. More advances in molecular modeling for enzyme-catalysis syntheses are expected, allowing for a greater number of biocatalytic techniques based on the enzymes that have been optimized or engineered by rationalized protein engineering. The organic chemists mostly have successfully used these custom-made biocatalysts (the isolated pure enzymes, the recombinant genetically modified microorganisms, also known as the designer cells), an important milestone in the enzyme catalysis process in organic synthesis is into generally accepted synthetic technology for academia as well as industries.


Using sunlight to solve energy shortage and pollution problems is still a hot but challenging issue. Because of this, we have demonstrated a novel and simple approach to fabricating a 2D shell array structure to enhance the interaction between incident light and the material. The enhancement remarkably increased the two-photon excitation efficiency of the material and, utilizing the two-photon induced electron–hole pairs in ZnO, we realized photocatalysis under monochromatic visible light for the first time. The method and theory described in this paper provide the basis for realizing high-efficiency sunlight-driven photocatalysts and also show a new way to improve the performance of photoelectric and photonic devices.

In the invention, the probes are obtained by an effective synthesis method, the copper ion selectivity is high, and the detection of copper ions can be realized on the basis of optimization of experiment foundation.


It firstly evaluates the cost efficiency of listed logistics companies in Chinese three developed regions with the metafrontier function during the time of 2000-2009.The result shows that these three regions' stochastic frontiers can be enveloped by a metafrontier curve.The technology gap ratio(TGR) among these three regions reveals significant difference.Considering the technology level and the cost efficiency,the enterprises in Circum-Bohai-Sea Region are best,the enterprises in Yangtze River Delta are second,and the enterprises in Zhujiang River Delta are third.From 2002 on,the TGR of Circum-Bohai-Sea Region and Yangtze River Delta began to exceed that of Zhujiang River Delta.The result also shows that good macro-economic background,unique product and service,faster assets turnover are quite beneficial to improving cost efficiency of logistics companies,but industry administrative monopoly hinders the promotion of cost efficiency.These conclusions demonstrate that improvement of the differencial-service level is an effective way to promote cost efficiency for listed logistics companies.The companies should pay more attention to the utilization efficiency of asset in stead of the short-term profitability.Government should make efforts to enhance the coordinating and comprehensive management competence of the units of trafic and transportation.


The influence of Fe72.5Cu1Nb2Mo1.5Si14B9 nanocrystalline alloy annealing temperature on the structure and magnetic properties has been investigated. The heat treatment temperature of nanocrystalline soft magnetic alloy Fer2.5Cu1Nb2 Mo1.5Si14B9, which allows reaching the maximum value of the initial magnetic permeability, was found to be 15-20° higher than that ensuring the minimum coercive force. The relation between the numerical values of the coercive force, the initial magnetic permeability and the magnetic hysteresis loop rectangularity factor allows optimizing the mode of nanocrystalline alloy heat treatment.


The article emphasizes the importance of taking a broad approach to understanding the act of teaching, especially in the context of teacher evaluation. It attempts to shift the commonly held notion of teaching as a one-directional act of instruction provided by teachers with the aim to inform, help, and advise learners in their efforts to attain pre-set curricular goals. The wider stance takes into consideration teacher-student relationships and various overt and subtle acts of differentiation and scaffolding that the teacher carries out to facilitate effective student learning and enhance student motivation and engagement. Such a wider perspective is especially relevant in developing rubrics for assessing instruction quality in an environment largely dominated by discourses on assessment and accountability in education—both in teaching and learning.

The paper analyzes the process of creation of Russian state authorities in the Chechen Republic during the active phase of the Counter-Terrorism operation (autumn 1999 - spring 2000). At the time, emergency military governments existed in Chechnya alongside civilian governments, taking the form of military commandant's offices. Sharp discussions were held on the issue of the political future of Chechnya. Despite the proposals to introduce direct rule and preserve the emergency system of government bodies, Russian President Vladimir Putin decided in June 2000 to gradually transfer the powers of the civil Administration headed by Akhmat A. Kadyrov.


Falls remain an important problem in older people. There is strong evidence that falls can be prevented with appropriately designed intervention programs. To start a targeted fall prevention program, a first step is to identify those at high risk of falls. Sensor-based tests hold great promise for more frequent and accurate assessment of fall risk in clinical and home settings. The aims of this study were to (a) empirically examine the feasibility of the iStoppFalls (Information and communications technology–based System to Predict & Prevent Falls) assessment, a Kinect and inertial sensor-based test for regular and unsupervised fall risk assessments at home, (b) investigate the experience of older adults with this home-based self-assessment, and (c) make recommendations for future assessments. The iStoppFalls assessment system was installed into the homes of 62 community-living older people in Australia, Germany, and Spain for the duration of 4 months. Participants were asked to perform at least 1 assessment each month. The system use and the user experience were evaluated. To our knowledge, these are the first results on the long-term use of an unsupervised directed routine fall risk assessment system at private homes. In total, 241 assessments were independently performed by the participants. Most participants felt positive about their experience and could see themselves continuing with the assessment on a regular basis. Through the analysis the user motivation, the design and selection of appropriate tests, the user feedback, the reliability and usability of the applied technology, the frequency and duration of the assessment and the safety and support aspects were identified as important characteristics of a home-based self-assessment. The findings demonstrate the feasibility of a sensor-based self-assessment for fall risk but also highlight that further work is necessary. Future research should consider the necessary design requirements identified by this study.


The article deals with the institutional economics approach to analyzing the cultural sector of the Russian economy. Some specific characteristics of cultural sphere are described, such as features of cultural products, value of culture and arts, information asymmetry and pricing particularities at the market for cultural products. Research of the cultural sphere under this heading tends to deviate from the conventional economic research. Quality differentiated inputs raise a number of questions about the organization of creative activities. The author concentrates on the origin of non profit firms, applying contract theory arguments. The paper examines the public support of culture through an economists lens and offers typical empirical findings based on that perspective.


Autonomous mobile agents have been purported as a promising new alternative to traditional distributed computing approaches, bringing many advantageous features. Notwithstanding this, mobile agent technology has yet to see wide deployment in open networks like the Internet. The lack of interoperability between agent systems has impaired such progress. Moreover, fears of security breaches by malicious agent platforms has been a chief contributing factor in the lack of capital investment in Internet agent technology. The attraction of the mobile agent paradigm is diminished if the agent owner cannot trust the results of its deployed agents. However, as in other distributed systems, appropriately applying traditional distributed systems security techniques and incorporating trusted third-parties can discourage and detect bad behaviour by remote systems. This paper presents the TAPS architecture for mitigating security risks from malicious agent platforms. The TAPS architecture uniquely adapts highly standardised network security techniques (appropriately in an agent framework) so that previously untrusted agent platforms are held more accountable. With a key objective being compliance to the Mobile Agent Facility specification, a large number of agent systems can readily utilise the features of this security architecture. The TAPS architecture provides a 'middleman' server that anonomises authenticated agent entities in agent itineraries. We believe that the TAPS architecture will be a substantially more robust approach for protecting mobile agents than existing mobile agent threat countermeasures which tend to be piecemeal and inflexible in nature.


The insulin hexamer is an allosteric protein exhibiting both positive and negative cooperative homotropic interactions and positive cooperative heterotropic interactions (C. R. Bloom et al., J. Mol. Biol. 245, 324–330, 1995). In this study, detailed spectroscopic analyses of the UV/Vis absorbance spectra of the Co(II)‐substituted human insulin hexamer and the 1H NMR spectra of the Zn(II)‐substituted hexamer have been carried out under a variety of ligation conditions to test the applicability of the sequential (KNF) and the half‐site reactivity (SMB) models for allostery. Through spectral decomposition of the characteristic d → d transitions of the octahedral Co(II)‐T‐state and tetrahedral Co(II)‐R‐state species, and analysis of the 1H NMR spectra of T‐ and R‐state species, these studies establish the presence of preexisting T‐ and R‐state protein conformations in the absence of ligands for the phenolic pockets. The demonstration of preexisting R‐state species with unoccupied sites is incompatible with the principles upon which the KNF model is based. However, the SMB model requires preexisting T‐ and R‐states. This feature, and the symmetry constraints of the SMB model make it appropriate for describing the allosteric properties of the insulin hexamer. Proteins 26:377–390 © 1996 Wiley‐Liss, Inc.

Intelligent speed adaptation (ISA) is a speed control technique that uses digital road mapping, global positioning systems and in-vehicle technology to alert drivers of the prevailing speed limit. The first UK trials of the system will be conducted in Leeds by Leeds ITS and MIRA Ltd. Four field trials, each consisting of 20 volunteers, will be used to evaluate the system. The drivers will be monitored for one month with the system switched off, four months with it on and then a final month with ISA off again. Another trial will be conducted with 20 fleet vehicles. The ISA project is the second phase of DfT-funded research into vehicle speed control. The first phase involved external vehicle speed control using a beacon system. Car manufacturers have not been involved with the ISA technology. The future for ISA is discussed.


In this paper, we address the problem of multisensor management for multi-target tracking via labeled random finite sets (LRFS) in sensor network systems which require both precision and real-time. Considering the optimal multisensor management strategy (proposed in [1] named joint decision making (JDM) algorithm) suffers from the high-dimensional computational complexity, to compromise between tractability and fidelity, an alternative multi-sensor management strategy is proposed. By sequentially calculating the Cauchy-Schwarz (CS) divergence between global generalized Covariance Intersection (GCI) fusion result and the GCI fusion result of two sensors, the JDM algorithm is simplified as a hybrid decision making with a two-dimensional optimization problem, which is referred to as the HDM algorithm, and meanwhile the proposed HDM algorithm is superior to the independent decision making (IDM) algorithm [1] in precision due to the IDM algorithm completely ignores the correlation among sensors. The computational complexity of the proposed method is also provided by comparison with the JDM and IDM algorithms. The efficiency as well as the performance of the proposed method is well demonstrated in a challenging multisensor multi-target tracking scenario by numerical results.


Suppose that a device is subjected to shocks and that denotes the probability of surviving k shocks. Then is the probability that the device will survive beyond t, where is the counting process which governs the arrival of shocks. A-Hameed and Proschan (1975) considered the survival function H(t) under what they called the pure birth shock model. In this paper we shall prove that is IFRA and DMRL under conditions which differ from those used by A-Hameed and Proschan (1975).


Japanese speakers start interpreting sentences even befor e the clause-ending predicate is read or heard. We report two ques tionnaire studies that suggest that the possible semantic r elations between NPs are critical in determining the interpret ations pursued. Although the properties of individual NPs su ch as animacy are important, interpretation is modulated by th e relations that may hold between NPs (e.g., possessor relati ons).


We associate Hamiltonian homological evolutionary vector fields – which are the non-Abelian variational Lie algebroids' differentials – with Lie algebra-valued zero-curvature representations for partial differential equations.


In this paper, some new exact solutions for the vari able-coefficient generalized KdV-mKdV equation (VGKdV- mKdV) with nonlinear terms of any order are obtained by using the generalized Jacobi elliptic functions expansion method with computerized symbolic computation, some of these solutions are degenerated to soliton-like solutions and trigonometric function solutions in the limit cases, which shows that the applied method is more powerful and will be used in further works to establish more entirely new exact solutions for other kinds of nonlinear partial differential equations with nonlinear terms of any order arising in mathematical physics.


Culturally sensitive health interventions have proven to be vitally important for the elimination of the health disparities that Black Americans face. The purpose of this study was to illuminate the role and importance of health behavior racial typicality and racial identification in how Black Americans view and engage in health behaviors. Black Americans completed racial identity measures and rated a variety of both health-promoting and health-compromising behaviors on whether they were more typical of Blacks or Whites (i.e., racial typicality), personal importance, and frequency of engagement. Results indicated the extent to which health behaviors were viewed as relatively more descriptive of Blacks (rather than Whites) was associated with higher perceived importance and greater frequency of engagement, particularly among those reporting higher levels of nationalist racial identification. Finally, health behavior importance mediated the relationship between racial typicality of the behavior and engagement in the behavior. The results of the study are discussed in terms of their implications for providing empirical support for the necessity of culturally tailored interventions in eliminating Black American health disparities.


Virtual reality systems have dealt with relatively sparse datasets for their operation in the representation of real world situations. This lack of detail in the definition and presentation of the modelled environment to the user, can constitute a serious loss in accurately bring across the correct impression of the situation. This deficiency can be put down to two reasons: the inability of modelling systems to conveniently capture large quantities of information about a real situation; and the inability of the target presentation systems to render large volumes of model information sufficiently quickly to cope with a real-time display requirement. A combination of techniques are used to generate model information automatically. In essence, a specification and a set of rules is supplied to the generation engine describing in loose detail the nature of the scene to be represented. These rules are then used in combination with various algorithms to produce the desired effect. The authors discuss the regeneration of database techniques for creation and maintenance of large models.

The periocular region has recently emerged as a promising trait for unconstrained biometric recognition, specially on cases where neither the iris and a full facial picture can be obtained. Previous studies concluded that the regions in the vicinity of the human eye - the periocular region- have surprisingly high discriminating ability between individuals, are relatively permanent and easily acquired at large distances. Hence, growing attention has been paid to periocular recognition methods, on the performance levels they are able to achieve, and on the correlation of the responses given by other. This work overviews the most relevant research works in the scope of periocular recognition: summarizes the developed methods, and enumerates the current issues, providing a comparative overview. For contextualization, a brief overview of the biometric field is also given.

Abstract : Since the fall of the Soviet Union Russia has yet to implement an effective state ideology to endear the state to its people. Eurasianism could provide a possible solution for the state as a concept that places Russia in a unique place between Europe and Asia rather than a part of either Europe or Asia. This thesis analyzes the concept of Eurasianism, its origins, its most prolific modern proponent, and the potential for a state sponsored Eurasianist ideology. Eurasianism itself focuses on a unique role for Russia in the realm of international affairs. This concept, in turn, provides a form of Russian exceptionalism to its people. The Russian state can theoretically use such an ideology to provide a coherent argument against Westernization and liberal economic reforms in order to maintain control of the country. Furthermore, the concept of Eurasianism can also serve as a means to provide Russians with a sense of Great Power status in line with that of the former Soviet Union.
