Heat-Labile Enterotoxin Promotes Escherichia coli Adherence to Intestinal Epithelial Cells

ABSTRACT Given recent evidence suggesting that the heat-labile enterotoxin (LT) provides a colonization advantage for enterotoxigenic Escherichia coli (ETEC) in vivo, we hypothesized that LT preconditions the host intestinal epithelium for ETEC adherence. To test this hypothesis, we used an in vitro model of ETEC adherence to examine the role of LT in promoting bacterium-host interactions. We present data demonstrating that elaboration of LT promotes a significant increase in E. coli adherence. This phenotype is primarily dependent on the inherent ADP-ribosylation activity of this toxin, with a secondary role observed for the receptor-binding LT-B subunit. Rp-3′,5′-cyclic AMP (cAMP), an inhibitor of protein kinase A, was sufficient to abrogate LT's ability to promote subsequent bacterial adherence. Increased adherence was not due to changes in the surface expression of the host receptor for the K88ac adhesin. Evidence is also presented for a role for bacterial sensing of host-derived cAMP in promoting adherence to host cells.
Livestock husbandry and its impact on employment generation in Aligarh District, U.P. (India)

Livestock husbandry is an important sector of agriculture economy. It plays a vital role in household nutritional security, increased income, and employment generation. Livestock farming, however, has been one of the most important value adding farming systems adopted in different countries. The animal husbandry and dairying sectors have come to play an increasingly significant role in the development of the India. Though milk, meat and egg production has grown manifold since independence, there is need for further increasing production from this sector. Present study was aimed to find out the structure of the livestock development and livestock oriented employment for various socio- economic groups in Aligarh district of Uttar Pradesh. It was found that the level of employment generated or workforce absorption in livestock sector is determined by the size of operational holding as well as social level of the livestock rearers. It revealed that marginal, small and medium size of holding farmers employed about 27- 28% of total workforce in different operations of livestock husbandry. Similarly, socially backward category of farmers like other backward caste (A Category of backward group of the people in India) showed highest percentage (52.85 %) of workforce involve in this sector to cropping system. Key words: Buffalo, Growth, Employment, Livestock, Socio-economic composition.
Showrooming vs. Competing: How does Brand Selection Matter?

In this study, we empirically examine the effect of local shoe store openings on the sales of a competing, major online shoe retailer. Both showrooming and competing effects can play a role: Under the showrooming effect, the local store opening can lead to more online sales for the online retailer, whereas the competing effect created by the local store opening can substitute away the demand for the online retailer. We examine when one effect dominates the other by classifying local stores into single- and mixed-brand stores. We find that the showrooming effect is dominant for a single-brand store opening, and the competing effect is dominant for a mixed-brand store opening. Our work contributes to the multi-channel literature by studying the channel effects across different retailers. The findings also provide novel insights through identifications of both positive and negative store opening effects on online sales.
Approaches to reduce the latency for high priority traffic in IEEE 802.1 AVB networks

The IEEE 802.1 Audio Video Bridging (AVB) standard is increasingly seen as a next generation real-time communication system for various application domains. The most important requirements are a short latency and a low jitter of the data transmission. One of the biggest impacts on the latency and the jitter of a reserved real-time stream is the interfering non real-time traffic. This paper presents some possible approaches under discussion within AVB community to mitigate the effect of such interference. A case study using one of the approaches is described and a simulation model is implemented as a proof of concept.
Approaching Sustainability through Stakeholder Involvement

Until the last decade of the 20th century, the environmental aspects of the sport industry very seldom received any attention in the societal debate. The very same year as the UNEP summit on Environment and Development was held in Rio, negative environmental aspects on the hosted city occupied space from the sport broadcast of the Summer Olympics in Barcelona. Despite an ambitious environmental programme, Greenpeace dubb ed the Sydney Olympics with the title "Green Games Dirty Sponsors ", based on criticism on bad labour conditions and environmental practices among same of the games sponsors. Golf tournaments similar to other large-scale events contribute to environmental change and degradation mainly through transports of goods and people, waste generation and littering, erosion and compaction of soil. Golf, as a concept is also the target of criticism of environmental impacts related to the construction and operation of golf courses. Golftoumaments are dependent on the revenue from sponsor allowances and ticket sales. Could critic on how the event affects the environment or socio-economic aspects of the hosted community threaten the continuous success of these events? How do the involved stakeholders, i.e. visitors, sponsors, employees, supplier's etc., perceive the environmental aspects of the Volvo Scandinavian Masters? How could Volvo Scandinavian Masters involve these stakeholders in the design of environmental and socio-economic improvement programmes?
Two-layer hybrid control of an underactuated system

This paper demonstrates a new approach for model-based hybrid control of an underactuated system. The balancing of an underactuated inverted pendulum system is achieved using a reaction wheel. Specifically, a two-layer hybrid controller is proposed with control algorithms implemented into prioritized states from the calculated dynamic equations. The first layer controller uses the reaction wheel with feedback linearization to control the first priority parameter at the non-actuated joint. The second layer controller then governs the first layer controller to guide the actuated joint to reach the set point. The effectiveness of the hybrid controller on the underactuated dynamic nonlinear system is illustrated by simulations in MATLAB.
Semi-Markov Credit Risk Modeling for a Portfolio of Consumer Loans in the Kenyan Banking Industry

Based on simulations of implied values for credit worthiness over a period of 5 years for 1000 consumers, we establish a case for the semi-markov models as a proxy for internal credit risk models for a portfolio of consumer loans. With ample calibration, we prove the robustness of the semi-markov models in forecasting probabilities of default and loss given default. With a view of credit risk as a reliability problem, we generate credit risk indicators as qualifications of adequacy of a loan portfolio. This informs prospective holding of capital based on forecast delinquencies as opposed to the current retrospective practice that relies on the trigger event of default. We use Monte-Carlo simulation techniques to generate consumer ratings and adopt this to the Merton model to derive the initial probability transition matrix. Initial consumer rating is in accordance with industry practice using a credit score sheet backed by the logit model. The banking credit function could espouse the study results to fulfill regulatory credit risk capital requirements for consumer loans in line with the Central Bank of Kenya Prudential Risk Guidelines or banks in other jurisdictions compliant with the Basel banking framework.
The EasyPET: A novel concept for an educational cost-effective positron emission 2D scanner

The easyPET concept proposed here, protected under a patent by the University of Aveiro, aims to realize a simple and affordable small dimension Positron Emission Tomography (PET) scanner. This innovative system is based on a single pair of detectors and a rotating mechanism with two degrees of freedom reproducing the functionalities of an entire PET ring. A 2D imaging prototype has been designed, commissioned and engineered, targeted to high level education for physics, engineering and nuclear medicine students. In this paper the performance of the prototype is reported, with a focus on the imaging capability and on the measurement of the uncertainty in the reconstruction of the source position. In addition, a detailed analysis is dedicated to the slice sensitivity and in particular to the effect of the energy threshold on the coincidence event selection.
Entrepreneurship and Regional Development: A Theoretical Framework

Abstract A theoretical framework is developed for examining entrepreneurship at the regional (provincial) level It is argued that conditions and systems at the national and state levels provide the foundation for regional entrepreneurship. Differences in entrepreneurship among regions can be explained by differences in regional resources which include enterprising individuals who live or move to the regions. Regional resource can be group into natural resources, infrastructure and other location advantages; demographics and markets in the region; financial resources; and the structure of the region’s industry. Other resources are human capital and the socio-cultural context. Regions can be placed on a continuum of munificence-depletion in relation to their resources. It is argued that regions at both ends of the continuum would be unattractive to entrepreneurship.
Demand Side Management to Minimize Peak-to-Average Ratio in Smart Grid

In this paper, a demand side management (DSM) technique for minimizing the peak load of the electric grid is proposed. The grid optimization problem is formulated and analyzed to find the optimized strategies. A smart power system with multi-residential end-users connected to a single energy source is considered. The end-users attempt to minimize peak-to-average ratio (PAR) of the electric grid by using energy scheduler (ES) as well as their energy production and storage strategies. Some end-users posses renewable energy sources (RESs), distribution generators (DGs), storage devices or both. Users charge their storage devices at low-demand periods and discharge them at high-demand periods. Likewise, end-users produces electricity during the peak hours to minimize their energy cost.
The Integrated Information Center concept

The Integrated Information Center concept is conceived as a response to the fragmentation in media and sources of information, and the concomitant breach in information services, particularly between Information Systems and the library. The range of information services which can be offered through department level Integrated Information Centers varies with the nature and level of personnel and technological support available. © 1991 John Wiley & Sons, Inc.
Information asymmetry and investor valuation of IPOs: top management team legitimacy as a capital market signal

The condition of information asymmetry between current owners and potential IPO investors creates a context wherein the legitimacy of the top management team (TMT) may serve as a valid signal of value to potential investors. The results confirm our hypotheses that TMT legitimacy is negatively correlated with post-IPO stock value run-up. Our results support a previously unexplored view of the TMT as an important signal of value in IPOs, and suggest that dual benefits accrue to the TMT selection process in IPO firms.

Reexpression of Prior Stroke Symptoms in Adults: When is a Mimic a Mimic?

A “stroke mimic” refers to any clinical condition that causes neurological symptoms clinically indistinguishable from a cerebral lesion that affects a vascular distribution, but is not caused by ischemia. One subtype of stroke mimic, termed stroke reexpression, is a form of mimicry in which previously recovered or improved stroke symptoms recur in the setting of a neurological disturbance (seizure, hypoperfusion state) or a systemic disturbance (toxic, metabolic, infectious). Many reports of stroke reexpression exist in the literature and are well known to clinicians, but there has been no consensus regarding terminology that has been published to date. The purpose of this review is to summarize several examples of stroke reexpression and propose simple, useful criteria for this clinical condition.

Transmit Beampattern Design in Range and Angle Domains for MIMO Frequency Diverse Array Radar

The frequency diverse array (FDA) has a range-angle-dependent transmit beampattern, which can provide the potential capability for novel radar application. However, the basic FDA's beampattern is periodic in range and coupled in range and angle dimensions, which limits the application of FDA in radar field. In this letter, we propose a novel FDA model with nonmonotone increasing frequency offset to form a narrow pencil beam, which eliminates the range periodicity and coupling of range and angle domains. Combining this new FDA with multiple-input–multiple-output radar, not only can multiple narrow pencil beams be formed to track multiple targets simultaneously, but also a flat-top transmit beampattern for targets searching can be synthesized. Simulation results show the effectiveness and outperformance of the proposed scheme compared to the existing Log-FDA, which uses the logarithmically increasing frequency offset.
The Development And Management Of Organizational Partner Satisfaction

While the development of a partner orientation is critical for the achievement of strategic organizational objectives, little is known about the components of such an orientation and how they impact on partner satisfaction in service operations contexts. The objective of this study is to establish the antecedents of partner satisfaction in a complex service operations context. The achievement of partner satisfaction can be seen as being particularly important, as it forms the basis for partners’ willingness to remain in a partnership. This is crucial in public sector contexts in which partnership work is usually concerned with the achievement of long-term strategic objectives. This study contributes to the wider stakeholder literature and provides managerial implications for public administration.
Resonant quantum gates in circuit quantum electrodynamics

We propose the implementation of fast resonant gates in circuit quantum electrodynamics for quantum information processing. We show how a suitable utilization of three-level superconducting qubits inside a resonator constitutes a key tool to perform diverse two-qubit resonant gates, improving the operation speed when compared to slower dispersive techniques. To illustrate the benefit of resonant two-qubit gates in circuit quantum electrodynamics, we consider the implementation of a two-dimensional cluster state in an array of $N\ifmmode\times\else\texttimes\fi{}N$ superconducting qubits by using resonant controlled-phase and one-qubit gates, where the generation time grows linearly with $N$. For $N=3$, and taking into account decoherence mechanisms, a fidelity over 60% for the generation of this cluster state is obtained.
Malaria surveillance with multiple data sources using Gaussian process models

—A statistical framework for monitoring the health of a population should ideally be able to combine data from a wide variety of sources, such as remote sensing, telecoms, and of ﬁ cial health records, in a principled manner. Gaussian process regression is commonly used to visualise disease incidence by interpolating values across a map; in this article, we show how it can be extended to deal with many different types of information by introducing a ﬂ exible covariance structure across data sources. Combining many data sources in a single model provides a number of practical advantages, such as the ability to to automatically determine the importance of each data source through likelihood optimisation, and to deal with missing values. We show the basic idea with an application of malaria density modeling across Uganda using administrative records and remote sensing vegetation index data, and then go on to describe further extensions such as the incorporation of human mobility data extracted from mobile phone call detail records (CDRs).
Matrix for Chemical

MATCHIT proposes a platform for integrated chemical production and information processing based on encapsulation in super-molecular chemtainers decorated with short DNA tags for chemtainer– chemtainer and chemtainer–matrix interactions. Chemtainers are embedded in programmable MEMS hardware that enables chemtainer manipulation. The resulting interplay of autonomous molecular computation and external electronic chemtainer manipulation enable programmatic setup of complex reaction cascades that allow for automated chemical production of desired target molecules from a limited set of chemical resources. MATCHIT presents a computational framework that spans from physical simulations of its molecular constituents to formal domain specific calculi for automated program inference and heuristic algorithms for yield optimization of target compounds. To close the loop back to the real world, we propose a semi-automatic mapping of control algorithms derived by idealized formal calculi back to machine code that operates MEMS hardware.

The main objectives of this Special Edition are: first, to contribute in terms of theory development by integrating organisational and knowledge-based views on knowledge transfer in MNEs; and second, to bring fresh empirical evidence on the determinants of intra-MNE knowledge flows and the potentials of technological spillovers to domestic firms.
Social justice in the land of Cockaigne

The development of the public health profession is closely intertwined with movements striving for social justice. At no time in history can this be seen more clearly than during the 19th century when modern public health was born. Many of the great forefathers of public health, like Rudolf Virchow, Salomon Neumann, Louis Villerme and William Farr, were politically active, mostly on the left of the political spectrum, and some of them even participated personally in the revolutionary movements of the middle of the 19th century. They believed that the ultimate causes of ill-health could be found in the environment, particularly in the social environment, and that improvement of the population’s health could not be achieved without social justice.1 They were right, and stood in a long tradition which actually started long before the 19th century. This is illustrated by Thomas More’s Utopia , published in 1516. In this imaginary kingdom, located …
Hierarchical fault-tolerant control of a quadrotor based on fault severity

In this paper, a hierarchical Fault Tolerant Controller (FTC) for quadrotor aircrafts is developed. The proposed controller switches between suitable controllers according to the actuator fault severity. Low amplitude faults are tolerated using the inherent robustness of a regular Sliding Mode Controller (SMC). When fault magnitude increases, an Active FTC is activated. This controller uses the fault estimates provided by an Extended Kalman Filter (EKF) to recover the control loss. When a fault magnitude rises to dangerous values, an emergency controller is activated and the quadrotor continues its mission as a trirotor. Simulation results emphasize the robustness of the proposed controller in real environments where measurement noise and actuator faults affect severely the quadrotor.
Myocardial Perfusion Reserve in Ischemic Heart Disease

frequent among cardiovascular diseases, is actually increasing together with its most relevant consequence, that is, progressive myocardial dysfunction and heart failure. Accordingly, better prevention and management of CAD is needed to further reduce early cardiovascular mortality and morbidity, to prevent development of heart failure, and hence to improve life expectancy and quality of life and reduce health costs. More efficient control of CAD implies early detection and identification of new, reliable endpoints for prevention and treatment.
Survey of psychiatric disorders in a Taiwanese village population six months after a major earthquake.

BACKGROUND AND PURPOSE The catastrophic Chi-Chi earthquake of September 21, 1999 in Taiwan provided a unique opportunity to study the disaster's psychiatric impact on survivors. This study assessed the development of psychiatric disorders among residents in a Taiwanese village near the epicenter of the earthquake within 6 months of the disaster. METHODS A total of 442 of the 602 actual living residents of Tong-Chi village who were over 16 years of age and were present in the community at the time of the earthquake were included in this population survey. Subjects were interviewed by psychiatrists using the Mini-International Neuropsychiatric Interview and questionnaires to collect demographic information and risk factors for psychiatric disorders 4 to 6 months after the earthquake. RESULTS The prevalence rates were 9.5% for current major depression, 2.8% for past major depressive episode, and 7.9% for post-traumatic stress disorder (PTSD). Females had significantly higher rates of most psychiatric disorders. After controlling for covariates, the significant risk factors for PTSD were female gender and having sought medical service after the earthquake. Significant risk factors for major depressive episode were divorced/widowed status, education level equal to or below primary school, and prominent house damage. CONCLUSION This population survey of earthquake disaster survivors found an increased prevalence of psychiatric disorders after exposure to a catastrophic earthquake. These results highlight the need for prompt therapeutic attention to residents of earthquake disaster areas after the event.
