When Migrants Overstay Their Legal Welcome: A Proposed Solution to the Guest-Worker Program

A number of developed countries have implemented guest-worker programs in recent decades. Its basic feature is the temporary presence of the foreign guest-workers. The problem with such programs is that there is little to prevent these guest-workers from entering the illegal job market and overstay their legal welcome, which is the reason why these programs became unpopular over time. This paper argues that a well-designed guest-worker program could be acceptable to host countries and could be beneficial for all parties concerned. It presents a host country immigration policy that tries to achieve these objectives by raising the likelihood that guest-workers return to their home country when the permissible time period elapses, and that reduces the number of immigrants entering the country illegally. The policy has three components and is based on legal responsibility by the guest-workers, new insurance markets, and cooperation with the sending country or countries.
Modelling and Simulation of Non-Ideal MAGIC NOR Gates on Memristor Crossbar

Memristors, as a consequence of their unique properties like non-volatility, scalability, and compatibility with existing CMOS fabrication technologies, had been of key interest to the circuit designers exploring the beyond-CMOS regime. Memristors could be utilized for implementation of both memory systems and logic computational systems and hence is a promising circuit element for implementing future non-Von Neumann type architectures. Memristors fabricated onto a crossbar structure provides a scalable and robust architecture for memristor-based computational systems. However, all the works on memristor-based systems to date are based on ideal models, ignoring the process variations and parasitics that can arise in actual circuit implementations. The parasitic components like interconnect resistance and capacitance in crossbar structure play a crucial role in circuit operation as the device dimensions are scaled down into the deep sub-micron regime. Also the parameters of individual memristors, especially the $\mathrm{R}_{on}$ and $\mathrm{R}_{off}$, of the memristors can be greatly affected by the fabrication process variations. These non-idealities are explored in this paper for the implementation of a MAGIC NOR gate on a 2D memristor crossbar. The simulation of a non-ideal MAGIC NOR gate model is presented and the observations are discussed.
Modified Unified Control of VSC-HVDC Based Offshore Wind Farm Connected to Onshore LargeScale Photovoltaic Power Station

In this paper, a new configuration for a multi-terminal offshore wind farms based VSC-HVDC and large scale photovoltaic system using modified unified adaptive linear neuron (Adaline) algorithm is presented. In the offshore station, the permanent magnet synchronous generator (PMSG)-based wind turbines are tied to the bus via back-to-back converters and a step-up transformer. The large scale photovoltaic power is connected to the dc bus between the offshore voltage source converters (VSC) and onshore VSC-HVDC stations via a modular multilevel converter (MMC). The Power management and the synchronization between two buses are achieved by controlling the two VSC converters. The performance of the topology proposed is tested using Matlab/Simulink during permanent operation mode and in the presence of DC fault.
Nonimmune Binding of Human Immunoglobulin A (IgA) and IgG Fc by Distinct Sequence Segments of the EibF Cell Surface Protein of Escherichia coli

ABSTRACT The eib genes of Escherichia coliencode surface-exposed proteins which bind immunoglobulins (Ig) such as the Fc fragment of human IgG (IgG Fc) in a nonimmune manner. The Eib proteins belong to a family which includes YadA ofYersinia, UspA2 of Moraxella, and DsrA ofHaemophilus ducreyi. This family of surface-exposed proteins shares several features, such as the ability to impart resistance to human serum complement and a tendency to exist as stable multimers. Four genes, eibA, eibC,eibD and eibE, were previously identified and cloned from ECOR-9, a strain from the E. colireference collection. EibC, -D, and -E bind human serum IgA in addition to IgG, but no IgA binding has been observed for EibA. Here, we report the cloning of a new eib gene, eibF, from a second strain of E. coli, ECOR-2. The product, EibF, has a relatively strong preference for IgA. Like the othereib genes, eibF attenuates serum sensitivity, occurs as a stable multimer, and is associated with a prophage. By subcloning portions of the eibA andeibF genes, we have identified distinct sequence segments sufficient to cause Ig binding, multimerization, and discrimination between IgA and IgG. The ability to multimerize is associated with a sequence close to the C terminus that is homologous to other family members such as YadA. Binding of IgG Fc is associated with a sequence that is highly conserved among all Eib proteins but otherwise unique. Binding of IgA is associated with a sequence of EibF that is not similar to any EibA sequence.
The influence of risperidone on cognitive functions in schizophrenia.

Introduction of the antipsychotics of the second generation (SGA) into the therapy of schizophrenia roused expectations that, finally, the cognitive dysfunction in schizophrenia could be eliminated by psychopharmacological therapy. The purpose of the study was to verify the effect of atypical antipsychotic risperidone on cognitive functions in schizophrenic patients. The study was carried out upon 48 male schizophrenic patients aged 21-47 years who were switched from the antipsychotics of the first generation (FGA) to the antipsychotic risperidone, due to intolerance, during the treatment. Intelligence, abstract and concrete thinking and mental speed, attention, and short-term non-verbal memory prior to the switch, one month after the switch, and three months after the switch to risperidone, were evaluated. One month after the switch the number of subjects with severe impairment of intellectual abilities decreased significantly from 62% to 15% and after three months the number was even lower-8%. The impairment of concrete and abstract thinking and mental speed also showed the same tendencies of decrease. The improvement of the cognitive functioning after the switch from the antipsychotics of the first generation to the antipsychotic risperidone is explained by removal of the antipsychotics of the first generation from the therapy and the consequential disinhibition of secondary cognitive impairments and by decreased average dose of anticholinergic and decreased number of patients who need anticholinergic therapy beside risperidone. The possibility of clear pro-cognitive effect of risperidone is suggested and its verification is proposed with strict control of other factors that improve cognitive functioning of schizophrenic patients during the treatment.
7-[(1R,2S,3S,5R)-6,6-dimethyl-3-(4- iodobenzenesulfonylamino)bicyclo[3.1.1]hept-2-yl]-5(Z)-heptenoic acid: a novel high-affinity radiolabeled antagonist for platelet thromboxane A2/prostaglandin H2 receptors.

A high-affinity thromboxane (TX)A2/prostaglandin (PG) H2 receptor antagonist, I-SAP [7-[(1R,2S,3S,5R)-6,6-dimethyl-3-(4- iodobenzenesulfonylamino)bicyclo[3.1. 1]hept-2-yl]-5(Z)-heptenoic acid] and its radiolabeled analog [125I]SAP (Mais et al., 1991) are characterized in the present study. I-SAP antagonized I-BOP ([1S-(1 alpha, 2 beta(5Z),3 alpha(1E,3R*),4 alpha)]-7-[3-(3-hydroxy-4- (4'-iodophenoxy)-1-butenyl)-7-oxabicyclo-[2.2. 1]heptan-2y l]-5'heptenoic acid) and U46619 [15S-hydroxy-11 alpha,9 alpha-(epoxymethano)-prosta-5Z,13E-dienoic acid)], two different TXA2/PGH2 mimetics, induced aggregation of washed human platelets in a similar manner (pA2 of 8.11 +/- 0.09, Kd = 7.8 nM, n = 3; pA2 = 8.01 +/- 0.05, Kd = 9.7 nM, n = 8, respectively). I-SAP also had agonistic activity, producing platelet shape change (EC50 = 9.7 nM +/- 0.6 nM at pH 7.4, n = 3) which was blocked by pretreatment of platelets with SQ29548 ([1S-(1 alpha,2 beta(5Z),3 beta,4 alpha)]-7-[3-[[2- [(phenylamino)carbonyl]hydrazino]methyl]-7-oxabicyclo[2.2. 1]hept- 2-yl]-5-heptenoic acid), a TXA2/PGH2 receptor antagonist. Radioligand binding studies were performed with [125I]SAP using washed human platelets. Competition of three agonists and four antagonists for binding with [125I]SAP was determined. The compounds showed the appropriate rank order potencies, including stereoselective competition by a pair of stereoisomeric antagonists. In washed human platelets, the Kd for I-SAP was 468 +/- 49 pM and the maximum binding (Bmax) was 2057 +/- 156 sites/platelet at pH 7.4 (n = 6). The Bmax was significantly increased 49% to 3072 +/- 205 sites/platelet at pH 6.5 (P less than .01 but the Kd was unchanged (490 +/- 18 pM, n = 6). (ABSTRACT TRUNCATED AT 250 WORDS)
LOYALTY TO A BRAND AND ITS EXTENSION IN HIGH INVOLVEMENT PURCHASES

This study compares the attitude of consumer loyalty and its antecedents towards the mother brand and its extension, in high involvement purchase context. The significant contribution of this research is that it provides insights about attitudinal drivers of loyalty towards the brand extension and not just perceived loyalty. Data was collected from a total of 1038 respondents using a questionnaire and independent samples t-tests were conducted to compare the mean scores between the attitudinal antecedents for consumers of the mother brand customers and its extensions. Results indicated that loyalty for brand extension was significantly different for the construct of brand loyalty and dealer loyalty, while no such difference was observed for antecedents like trust, satisfaction, brand image and perceived service quality. In high involvement purchase situations, where the intermediary was the point of contact with the consumers, the loyalty behaviour is significantly related to the attitude towards the intermediary.

This work presents a new embedded wireless system that allows measuring the effects of ionizing radiation on different electronic devices. The security, reliability and ease of the measurement processes are described by means of an architecture based on wireless monitoring and control fully configurable by the user. All the devices used for the development of the system are low cost and of easy accessibility, such as cell phones or tablets, micro-controllers and Commercial-Off-The-Shelf (COTS) devices. Its application and validation is shown in the study of the counting of singular events in a static RAM exposed to radiation in the TANDAR facility in Buenos Aires, Argentina. Future applications and expected results associated with relevant projects currently underway are also presented.
A note on "Approximation schemes for a subclass of subset selection problems", and a faster FPTAS for the Minimum Knapsack Problem

Pruhs and Woeginger prove the existence of FPTAS's for a general class of minimization and maximization subset selection problems. Without losing generality from the original framework, we prove how better asymptotic worst-case running times can be achieved if a $\rho$-approximation algorithm is available, and in particular we obtain matching running times between maximization and minimization subset selection problems. We directly apply this result to the Minimum Knapsack Problem, for which the original framework yields an FPTAS with running time $O(n^5/\epsilon)$, where $\epsilon$ is the required accuracy and $n$ is the number of items, and obtain an FPTAS with running time $O(n^3/\epsilon)$, thus improving the running time by a quadratic factor in the worst case.
Risk and avoidance strategy for blocking mechanism of SDN-based security service

Software-Defined Network (SDN) is the dynamic network technology to address the issues of traditional networks. It provides centralized view of the whole network through decoupling the control planes and data planes of a network. Most SDN-based security services globally detect and block a malicious host based on IP address. However, the IP address is not verified during the forwarding process in most cases and SDN-based security service may block a normal host with forged IP address in the whole network, which means false-positive. In this paper, we introduce an attack scenario that uses forged packets to make the security service consider a victim host as an attacker so that block the victim. We also introduce cost-effective risk avoidance strategy.
Nosocomial Respiratory Syncytial Virus Infections Prevention and Control in Bone Marrow Transplant Patients

Abstract Objective: To assess the effectiveness of a multi-faceted infection control strategy in limiting the nosocomial transmission of respiratory syncytial virus (RSV) infection to patients in a bone marrow transplant (BMT) unit. Design: Before/after trial. Setting: University-affiliated tertiary cancer center. Patients: Adult BMT recipients hospitalized during two consecutive wintertime community outbreaks of RSV infection. Interventions: An infection control strategy against nosocomial RSV infection was implemented in the BMT unit in February 1993. The strategy involved prompt identification, isolation, and cohorting of RSV-infected patients; prompt therapy with aerosolized ribavirin; use of masks and gloves by anyone entering an infected BMT patient's room; screening visitors for respiratory symptoms; restricting visitation by all children under 12 years of age and all family members and other visitors with RSV symptoms; and restricting symptomatic hospital staff from working in the BMT unit. Results: After implementation of the multifaceted infection-control strategy, there were four cases of nosocomial RSV infection in 3,870 patient days (incidence density, 1.0 case/1,000 patient days) compared with 14 cases of nosocomial RSV infection in 3,152 patient days (incidence density, 4.4 cases/1,000 patient days) during the 1992-1993 RSV season (rate ratio, 4.4; 95% confidence interval [CI95], 1.4-17.9; P<.01). This decrease in incidence occurred despite a comparable prevalence of community-acquired RSV cases between the two seasons (2.2% vs 3.2% in 1992-1993 and 1993-1994, respectively; prevalence ratio, 0.7; CI95, 0.2-2.1; P=0.5) Conclusion: Institution of a multifaceted infection control strategy significantly reduced the frequency of nosocomial RSV infection in a high-risk group of adult BMT recipients
A new modeling capability for airport surface traffic analysis

Surface Traffic Limitations Enhancement (STLE) is a NASA-developed advanced modeling capability for simulating airport surface aircraft movement. STLE augments NASApsilas Advanced Concept Evaluations System (ACES), which is a fast-time computer simulation of nationwide airport and airspace traffic operations. STLE expands ACES software logic and data inputs and outputs to simulate individual aircraft surface trajectories through an airportpsilas terminal gate/ramp, taxiway and runway system. STLE models surface operations using a link-node modeling structure. The modeling simulates aircraft motion dynamics, tracks the movement of each flight, assesses the traffic situation, determines route assignment, detects and resolves potential conflicts, considers node required/planned crossing time constraints, and evaluates traffic throughput and delay. Inputs include specification of link and node graph components, gate and runway configurations, operating rules and procedures, and traffic and airport operating conditions schedules, typically for a 24-hour study period. Output statistics describe transit time and delay by flight and traffic loading as well as queues and transit times by link and node. Node transit control governs actual movement of each aircraft from a link into a node and movement from a node into a link, which determines delay propagation through the surface network. STLE distinguishes sequencing nodes (e.g., taxiway intersections) and complex nodes (e.g., gate, gate group) functions. Link transit control supports this nodal network analysis process by managing traffic movement along each link to deliver aircraft to a node. STLE provides a system of working pluggable modules that represent current operations. These pluggable modules are the foundation for subsequent replacement and supplemental models.
A Learning-Based Framework for the Automatic Segmentation of Human Sperm Head, Acrosome and Nucleus

Evaluating the morphology of the human sperm is one of the most important steps in the human semen analysis, which is the controversial aspect of the treatment of male infertility. Manual assessment of the corresponding parameters of human sperm morphology is a time-consuming, reader subjective and error-prone process. Therefore, developing the automatic methods is necessary to achieve the more accurate diagnosis. In this paper, we presented a learning-based framework for the automatic segmentation of the human sperm head particles, i.e., Acrosome and Nucleus. First, the homomorphic filtering is employed to correct uneven illumination and highlight each sperm from the background of an image. In the second step, sperm's heads are segmented using an introduced deep convolutional neural network (CNN). Then, a filling holes operation and geometric constraints are utilized to improve head segments. A Support Vector Machine (SVM) is used to classify each pixel of segmented heads to nucleus and acrosome regions. Finally, segmented acrosomes and nucleus are modified using opening and closing operations followed by isolated objects removing. The proposed method is validated on the expert delineated dataset with 20 images of human semen smears and obtains 0.94, 0.87, and 0.88 of Dice Similarity Coefficient for the head, the acrosome, and the nucleus segments, respectively. Our results indicate that the proposed method has outperformed the segmentation systems based on classical learning methods, in the accuracy and the reliability.
A Semantic Autonomous Video Surveillance System for Dense Camera Networks in Smart Cities

This paper presents a proposal of an intelligent video surveillance system able to detect and identify abnormal and alarming situations by analyzing object movement. The system is designed to minimize video processing and transmission, thus allowing a large number of cameras to be deployed on the system, and therefore making it suitable for its usage as an integrated safety and security solution in Smart Cities. Alarm detection is performed on the basis of parameters of the moving objects and their trajectories, and is performed using semantic reasoning and ontologies. This means that the system employs a high-level conceptual language easy to understand for human operators, capable of raising enriched alarms with descriptions of what is happening on the image, and to automate reactions to them such as alerting the appropriate emergency services using the Smart City safety network.
Survey on Biological Effects of Mobile Phone Radiation, Measurement Techniques and Radiation Shields

Microwaves are widely used in many applications. This made it possible for continent to continent communication. With this, one can reach the unreachable location by other means. Mobile phone communication is the marked field. This gives more freedom to the user to be anywhere and anytime. The advancements in the field of wireless technology in terms of sophistication and price reduction, made many to use the wireless products such as Mobile phone, Blue-tooth, Wi-Fi, etc., One of the important facets of this ubiquitous technology is the risk associated with this. It increases the interaction of electromagnetic fields radiation with the biological tissues of plants, animals and humans. This microwave affects biological ells in two ways, Thermal and Non-thermal. This persuades researchers to study the pros and cons of this inevitable technology. This paper reviews some of the vital studies which concluded the ill-effects of using Mobile-phone, some of the Specific Absorption Rate (SAR) measurement techniques, techniques to reduce the radiation levels and the significance of a new class material, a material which was the advent of 21st century i.e., Meta material in electromagnetic(EM) radiation reduction are presented.
Young Stars in the Camelopardalis Dust and Molecular Clouds. I. The Cam OB1 Association

The distribution of dust and molecular clouds in the direction of Galactic longitudes 132--158 deg and latitudes pm 12 deg is investigated. The maps of dust distribution in the area were plotted from the following surveys: the star counts in the DSS I database by Dobashi et al. (2005), the survey of the average infrared color excesses by Froebrich et al. (2007) and the thermal dust emission survey at 100 micrometers by Schlegel et al. (1998). The distribution of molecular clouds was taken from the whole sky CO survey by Dame et al. (2001). All these surveys show very similar cloud patterns in the area. Using the radial velocities of CO, the distances to separate clouds are estimated. A revised list of the Cam OB1 association members contains 43 stars and the open cluster NGC 1502. 18 young irregular variable and H alpha emission stars are identified in the area. All this proves that the star forming process in the Camelopardalis clouds is still in progress.
Control of a Photovoltaic System Connected to Grid

In this paper, we are interested in the quality of the electrical power supplied by a PV system connected to the grid, in terms of control of the current injected into the grid, as well as the control of the voltage at the point of common coupling. The proposed model introduces current and voltage cascade regulation loops based on conventional controllers type PI, which make it possible to regulate DC link voltage, to stabilize the voltage at the point of common coupling (PCC) on the AC side of the inverter, and to maintain the injected current to the grid in phase with the voltage. In order to demonstrate the feasibility and the effectiveness of the suggested control a simulation using the Matlab/Simulink software has been performed, to confirm that the proposed control model, is able during the permanent and transient operating conditions, of injecting an optimal power to the grid, with a unit power factor, while keeping the stable voltage at the point of common coupling, without exceeding the grid code requirements.
