Agent agreement protocols based on golay error-correcting code

In this paper, we propose simple protocols for enabling two communicating agents that may have never met before to extract common knowledge out of any initial knowledge that each of them possesses. The initial knowledge from which the agents start, may even be independent of each other, implying that the two agents need not have had previous access to common information sources. In addition, the common knowledge extracted upon the termination of the protocols depends, in a fair way, on the (possibly independent) information items initially known, separately, by the two agents. It is fair in the sense that there is a negotiation between the two agents instead of one agent forcing the other to conform to its own knowledge. These protocols, may be extended in order to support security applications where the establishment of a common knowledge is required. Moreover, the implementation of the protocols leads to reasonably small code that can also fit within resource limited devices involved in any communication network while, at the same time, it is efficient as simulation results demonstrate.
Rules, and Their Effects on Fiscal Policy

Fiscal rules aim at constraining public debt. In Sweden, a combination of procedural and numerical rules was introduced in response to the severe 1991 fiscal crisis. These rules have been effective: public debt has come down. The current fiscal framework does not rule out future fiscal crises, however. Spending is not sufficiently kept under control. Taxes are set procyclically, only to keep debt in check. Controls on debt sustainability require tighter spending rules, linked to levels of taxation.

Virtual equivalent system and stability criteria for discrete-time T-S model based fuzzy control systems

The stability of T-S model based fuzzy control systems for discrete, linear time-invariant plant and nonlinear time varying plant is analyzed with the help of virtual equivalent system concept and methodology. The main results developed in this paper indicate that the stability of the fuzzy control systems depends on the following conditions: First, the local model set covers the uncertainty of the plant; Second, the normalized membership function identifies the true model(s) of the plant; Third, each local controller stabilizes its corresponding local model.
Using Second Life to Enhance ACCEL an Online Accelerated Nursing BSN Program

To create a presence in Second Life (SL) the university college of nursing (CON) purchased four virtual islands in December 2007. The intent was to enhance distance education with immersion learning experiences for nursing students in SL. The Pollock Alumni House, classrooms, faculty offices, a library, a student welcome center, a public health office, a disaster scenario, a clinic, a hospital, and several patient avatars were created. Houses are being built for nursing students to experience different patient care scenarios during home visits. At least 20 nursing faculty and academic staff and three cohorts of accelerated nursing students (77) have avatars and have experienced class sessions. Faculty and students schedule office hours, engage in synchronous chats, and utilize the public health department and SL support groups for class exercises. Current exercises in the public health department include a module in which the student learns the role of the sanitarian. Students use a checklist to inspect restaurants and bars in SL. They are also able to view a video of an interview with a sanitarian. Another module introduces them to the WIC (Women, Infants, and Children) program. Future student activities related to public health include disaster planning, bioterrorism, evacuations, community assessment, windshield surveys, fund raising, and health education as well as other activities suggested by public health nurses and students. The possibilities are limitless because of the resources that exist in the virtual world, SL. The purchase of the first two islands, the initial buildings, and the creation of the public health department was funded by a research grant. Virtual environments offer many advantages for nursing education. Many nursing students say they learn best when they actually "do something," which indicates that they often prefer experiential learning. Rare but life-threatening patient situations can be experienced since the clinical environment can be realistically simulated. The student has the opportunity to practice repeatedly without causing harm to patients. During these simulations, active learning takes place, immediate feedback can be given for both correct and incorrect actions, errors can be corrected, and consistent experiences can be reproduced for all students. This technology is revolutionizing education and will meet the needs of the media savvy generations to come. It can also provide virtual experiences that nursing students may encounter in the clinical setting which are high risk and low volume, thus enhancing patient safety.
The choice among non-callable bonds and make whole, claw back and otherwise ordinary callable bonds

This paper seeks to explain determinates of the choice and the pricing of various types of callable and non-callable bonds. We find that the popularity of different types of callable and non-callable bonds is significantly related to the economic environment. In addition, the popularity of claw back bonds appear to be driven by agency considerations, make whole bonds by the debt overhang problem, ordinary callable bonds by the need by banks to deal with interest rate changes and non-callable bonds by the need to raise funds as cheaply as possible. All else equal, firms pay a higher offer spread for the flexibility to call a claw back bond early via a new share offering whereas issuers of make whole bonds are rewarded with a lower offer spread for restricting calls to circumstances that does not expropriate bondholder wealth.
Multi-service networks: flow configuration, pricing and incentive Stackelberg strategies

High-speed communication networks, such as B-ISDN and Internet, allow several types of network traffic to coexist in the same transmission medium and belong to the category of multi-service networks. Several new results on flow configuration, pricing and routing are presented in addition to overviews of relevant previous works. These derived by making use of the concepts Nash equilibrium, Pareto optimality and Stackelberg strategies borrowed from game theory. These are highlighted by means of illustrative examples. It is claimed the control-theoretic view on incentives in the theory of non-cooperative games provides for tools to solve various control and management problems in high-speed communication networks hence many QoS problems too.
A sub-100nA power management system for wireless structure health monitoring applications

Recently, the power management becomes significantly important for the ultra power wireless sensor node powered by energy harvesting devices. In this paper, a power management system from battery to wireless sensor node is proposed for wireless structure health monitoring applications. By using the proposed circuits, the power supply of a sensor network node is switched on only when some event is detected to reduce its average power consumption. In the proposed circuit, the nanopower reference is utilized to bias control circuits. Therefore, the proposed management system has an extremely low power consumption of less than 100nA standby current. The proposed circuits are implemented with a 1. 2µm CMOS process. Experimental results demonstrate the low power feature of the proposed power management system.
Efficient Use Of Sparse Adaptive Filters

We present a novel adaptive algorithm exploiting the sparseness of an impulse response for network echo cancellation. This sparseness-controlled improved proportionate normalized least mean square (SC-IPNLMS) algorithm is based on IPNLMS which allocates a step-size gain proportional to each filter coefficient. The proposed SC-IPNLMS algorithm achieves improved convergence over IPNLMS by estimating the sparseness of the impulse response and allocating gains for each step- size such that a higher weighting is given to the proportionate term of the IPNLMS for sparse impulse responses. For a less sparse impulse response, a higher weighting will be allocated to the NLMS term. Simulation results presented show improved performance over the IPNLMS algorithm during convergence before and after an echo path change has been introduced. We also discuss the computational complexity of the proposed algorithm.
Galanin Mediates the Pathogenesis of Cerulein-Induced Acute Pancreatitis in the Mouse

Objectives: Acute pancreatitis (AP) is characterized by pancreatic microcirculatory and secretory disturbances. As galanin can modulate pancreatic vascular perfusion, we sought to determine if galanin plays a role in AP. Methods: Acute pancreatitis was induced in wild-type and galanin gene knockout mice by intraperitoneal injections of cerulein. The severity of AP was evaluated (plasma amylase and lipase, myeloperoxidase activity, and acinar cell necrosis) with and without treatment with galanin or the antagonist galantide. Galanin receptor messenger RNA expression in mouse pancreas was measured by reverse transcription-polymerase chain reaction and Western blot analysis. Results: Galantide ameliorated AP, reducing all indices by 25% to 40%, whereas galanin was without effect. In galanin knockout mice, all indices of AP were reduced 25% to 50% compared with wild-type littermates. Galanin administration to the knockout mice exacerbated AP such that it was comparable with the AP induced in the wild-type mice. Conversely, administration of galantide to the galanin knockout mice did not affect the AP, whereas AP was ameliorated in the wild-type mice. The 3 galanin receptor subtypes are expressed in mouse pancreas, with receptor subtype 3 expression predominating. Conclusions: These data implicate a role for galanin in AP and suggest a potential clinical application for galanin antagonists in treatment.
Effect of Fat Embolism with Triolein Emulsion on Blood-Retinal Barrier

Background: Triolein emulsion is under investigation for supplemental use to open the blood-brain barrier during chemotherapy. The effects of triolein emulsion on the blood-retinal barrier (BRB) were investigated. Methods: Fat emboli were induced in 20 cats by injecting triolein emulsion through the carotid artery. At 30 min, 4, 12 and 48 h after embolization, electroretinography (ERG) and fluorescein angiography (FA) were performed. The eyeballs were enucleated for transmission electron-microscopic study. Results: FA revealed multiple leaking points at 30 min, and prominent diffuse leakage at 4 h when scotopic b-waves showed significant differences between the study and control eyes. Multiple focal disruptions of the blood vessels by fat vacuoles were found with electron microscopic study. ERG improved at 12 and 48 h, and the BRB appeared to be recovered on FA and electron microscopic studies after 48 h. Conclusion: An experimental embolism with triolein emulsion disrupted the blood retinal barrier. Delayed maximal change was observed, and it could be implicated in the latent interval of clinical fat embolism syndrome.
Expression of Steroidogenic Acute Regulatory Protein in Cultured Schwann Cells and Its Regulation by cAMP

Abstract: In steroidogenic cells the steroidogenic acute regulatory (StAR) protein plays a key role in the transport of cholesterol to the inner mitochondrial membrane, where the first step of steroidogenesis, the conversion of cholesterol to pregnenolone, takes place. cAMP is a known positive regulator of StAR gene expression and steroid biosynthesis in steroidogenic cells. As some steroids, such as progesterone, can also be synthesized de novo in the central and peripheral nervous systems and display neuroprotective and neurotrophic effects, we decided to verify the effect of cAMP on StAR gene expression in cultured Schwann cells. We observed that (1) in the presence of serum, forskolin, an agent known to elevate intracellular cAMP, induced both a morphological change and proliferation of cultured Schwann cells; (2) StAR mRNA and protein were expressed in Schwann cells; (3) unexpectedly, forskolin and 8 Br‐cAMP, a cell‐permeant analogue of cAMP, extinguishcd StAR gene expression; and (4) this response was similar in the presence or absence of serum.
A Trusted Source of Information

Background: Systematic reviews sponsored by federal departments or agencies play an increasingly important role in disseminating information about evidence-based programs and have become a trusted source of information for administrators and practitioners seeking evidence-based programs to implement. These users vary in their knowledge of evaluation methods and their ability to interpret systematic review findings. They must consider factors beyond program effectiveness when selecting an intervention, such as the relevance of the intervention to their target population, community context, and service delivery system; readiness for replication and scale-up; and the ability of their service delivery system or agency to implement the intervention. Objective: To support user decisions about adopting evidence-based practices, this article discusses current systematic review practices and alternative approaches to synthesizing and presenting findings and providing information. Method: We reviewed the publicly available information on review methodology and findings for eight federally funded systematic reviews in the labor, education, early childhood, mental health/substance abuse, family support, and criminal justice topic areas. Conclusion: The eight federally sponsored evidence reviews we examined all provide information that can help users to interpret findings on evidence of effectiveness and to make adoption decisions. However, they are uneven in the amount, accessibility, and consistency of information they report. For all eight reviews, there is room for improvement in supporting users’ adoption decisions through more detailed, accessible, and consistent information in these areas.
Event centrality and posttraumatic outcomes in the context of pervasive violence: a study of teachers in El Salvador

It is well established that the importance assigned to a trauma can affect one's recovery and psychological health in numerous ways. Event centrality is an increasingly popular construct that captures the tendency among survivors to reevaluate and possibly accommodate their worldviews posttrauma. The centrality given to trauma appears to serve as a “double-edged sword” in that this construct might factor prominently in both posttraumatic stress disorder (PTSD) and posttraumatic growth (PTG). Focusing on 257 violence-exposed teachers from educational departments throughout El Salvador, we examined whether the centrality assigned by the teachers to stressful life events uniquely predicted both PTSD symptomatology and PTG. Results revealed that event centrality was positively related to both PTSD and PTG, even when controlling for demographic factors, violence exposure, and depression. In addition, PTSD symptomatology and PTG were not associated with one another in this sample. In summary, these findings support the role of event centrality as a contributing factor for PTSD and PTG among persons exposed to pervasive trauma.
Probabilistic cascading event risk assessment

This paper describes an algorithm for the identification of rare events with high severities, potentially leading to blackouts in power systems, and the quantification of the risk a given system state holds. Based on the method of probabilistic load flow, probability density functions of the branch loadings under consideration of the forecast uncertainty are determined. From that branch tripping probabilities are derived. Using these tripping probabilities, numerous cascades are simulated. As the main output of this method the overall risk is calculated. This method is applied to the IEEE 118-bus test system extended by uncertainty data and outage statistics.
Do Poor Health Behaviors Affect Health‐related Quality of Life and Healthcare Utilization Among Veterans?: The Veterans Health Study

The impact of health behaviors on Health-Related Quality of Life (HRQoL) and HealthCare Utilization (HCU) was examined in a sample of male veterans. We examined the relationship between health behaviors (cigarette smoking, alcohol use, exercise, seat belt use, cholesterol level, and body mass index [BMI]), and HRQoL and HCU, among Veterans Health Study participants providing complete baseline (t0) and 12-month follow-up (t12) data. (Respective sample sizes were 1242 and 1397.) HRQoL measures were derived from the SF-36, expressed as physical component summary (PCS) and mental component summary (MCS) scores. Prospective 12-month outpatient and inpatient utilization data were obtained from a VA administrative database. Exercise and BMI were significant PCS predictors at t0 and t12, adjusting for age, social supports, education, employment status, and comorbidities. Smoker status was negatively associated with PCS only at t0. Nonproblem (no abuse) alcohol users had significantly higher t0 PCS scores than nonusers. Only current problem alcohol use was associated with lower MCS at t0 and t12 in multivariate analyses. Regarding HCU, current smokers had fewer medical visits than never smokers; alcohol nonusers had more medical visits than current alcohol users, current problem users, and former problem users. No behaviors were associated with mental health visits or inpatient stays. HRQoL is negatively affected by poor health behaviors. HRQoL and physical health may be improved by practitioners targeting these behaviors for preventive interventions. This study did not support an association between poor health behaviors and higher HCU. Future research should consider the effect of moderating variables on this relationship.
“A bit more truthful”: the validity of adolescent sexual behaviour data collected in rural northern Tanzania using five methods

Objective: To assess the validity of sexual behaviour data collected from African adolescents using five methods. Methods: 9280 Tanzanian adolescents participated in a biological marker and face to face questionnaire survey and 6079 in an assisted self-completion questionnaire survey; 74 participated in in-depth interviews and 56 person weeks of participant observation were conducted. Results: 38% of males and 59% of females reporting sexual activity did so in only one of the two 1998 questionnaires. Only 58% of males and 29% of females with biological markers consistently reported sexual activity in both questionnaires. Nine of 11 (82%) in-depth interview respondents who had had biological markers provided an invalid series of responses about sex in the survey and in-depth interview series. Only one of six female in-depth interview respondents with an STI reported sex in any of the four surveys, but five reported it in the in-depth interviews. Conclusion: In this low prevalence population, biological markers on their own revealed that a few adolescents had had sex, but in combination with in-depth interviews they may be useful in identifying risk factors for STIs. Self-reported sexual behaviour data were fraught with inconsistencies. In-depth interviews seem to be more effective than assisted self-completion questionnaires and face to face questionnaires in promoting honest responses among females with STIs. Participant observation was the most useful method for understanding the nature, complexity, and extent of sexual behaviour.
Capacity utilization dynamics and market power

In an intertemporal general equilibrium model with imperfect competition, we settle a relationship between factor utilization and markups, via the effect of capacity utilization rate changes on firms' market power when the demand for goods is uncertain. When competition is imperfect, the existence of capacity constraints introduces a distinction between demand and sales price elasticities. At given demand price elasticity, the price elasticity of sales will be smaller the larger the aggregate capacity utilization rateo In such a framework, capacity utilization aifects the propagation mechanism of exogenous disturbances in two ways. The first effect is similar to the effect that bottlenecks and stockouts would have in a perfectly competitive setup; the second effect is related to imperfect competition and works through market power and optimal markup changes. We study these interactions and their implications for the dynamic behavior of sorne key macro variables in response to various "structural" changes. We show that the same shock can have quite different short run effects depending on the characteristics of the initial stationary state (low or high capacity utilization rate).
Impact of Era, Type of Isomerism, and Ventricular Morphology on Survival in Heterotaxy

Background: Heterotaxy has been demonstrated to reduce survival. There are several different subgroups of patients, however, and no single study has had a large number of patients and analyzed survival across the different subgroups such as patients born in different eras, patients with right and left isomerism, and patients with biventricular or functionally univentricular hearts. This study pools previously reported data from Kaplan-Meier curves and performs such subgroup analysis. Methods: A systematic review of the literature was performed to identify studies reporting survival of patients with the so-called “heterotaxy” by means of Kaplan-Meier survival curves. Data were extracted from these survival curves and then pooled together. A polynomial regression was then used to generate a pooled survival curve. This was done for all patients, those born in a more recent era, those with right and left isomerism, and those with biventricular or functionally univentricular hearts. Results: Those born in the more recent era (after 2000) had increased survival compared to the overall cohort. Those with left isomerism tended to have a survival benefit compared to those with right isomerism until about 16 years of age, beyond which those with right isomerism developed a survival benefit. Those with biventricular hearts had a survival benefit compared to those with left isomerism. Conclusion: Survival in the so-called heterotaxy syndrome is based on several factors, which include era of birth, sidedness of isomerism, and whether the heart is biventricular or functionally univentricular.
