Addressing short term voltage stability problem - Part I: Challenges and plausible solution directions

This paper is the first of a two-part paper presenting issues related to short term voltage stability problem and then providing possible solution options that can ensure the security of the system. Lately power system planners are frequently encountering voltage problems in short term. Placement of dynamic VAR device in the system is one preferred option. However, there is little research done in the field of dynamic VAR allocation to ensure short term voltage stability and no industry grade tool exists. Part I explores the challenges faced while solving dynamic VAR allocation problem. The problem is complex as it requires proper selection of dynamic model; and consideration of contingencies and system dynamics in the optimization problem which leads to large problem size. Hence, this paper explores different solution methodologies; and finally proposes a novel approach to solve the optimization problem. Part II of this paper provides numerical results that demonstrate the application of the proposed approach.
Thought Speed, Mood, and the Experience of Mental Motion

This article presents a theoretical account relating thought speed to mood and psychological experience. Thought sequences that occur at a fast speed generally induce more positive affect than do those that occur slowly. Thought speed constitutes one aspect of mental motion. Another aspect involves thought variability, or the degree to which thoughts in a sequence either vary widely from or revolve closely around a theme. Thought sequences possessing more motion (occurring fast and varying widely) generally produce more positive affect than do sequences possessing little motion (occurring slowly and repetitively). When speed and variability oppose each other, such that one is low and the other is high, predictable psychological states also emerge. For example, whereas slow, repetitive thinking can prompt dejection, fast, repetitive thinking can prompt anxiety. This distinction is related to the fact that fast thinking involves greater actual and felt energy than slow thinking does. Effects of mental motion occur independent of the specific content of thought. Their consequences for mood and energy hold psychotherapeutic relevance.
Lone Star Tick-Infecting Borreliae Are Most Closely Related to the Agent of Bovine Borreliosis

ABSTRACT Although Borrelia theileri, the agent of bovine borreliosis, was described at the turn of the century (in 1903), its relationship with borreliae causing Lyme disease or relapsing fever remains undescribed. We tested the previously published hypothesis that spirochetes infecting Lone Star ticks (Amblyomma americanum) may comprise B. theileri by analyzing the 16S ribosomal DNAs (rDNAs) and flagellin genes of these spirochetes.B. theileri, the Amblyomma agent, and B. miyamotoi formed a natural group or clade distinct from but most closely related to that of the relapsing fever spirochetes. B. theileri and the Amblyomma agent were 97 and 98% similar at the nucleotide level within the analyzed portions of the 16S rDNA and the flagellin gene respectively, suggesting a recent divergence. The agent of bovine borreliosis might be explored as a surrogate antigen for the as-yet-uncultivatable Amblyommaagent in studies designed to explore the etiology of a Lyme disease-like infection associated with Lone Star ticks.
Current and novel approaches to vaccine development against tuberculosis

Antibiotics and vaccines are the two most successful medical countermeasures that humans have created against a number of pathogens. However a select few e.g., Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis (TB) have evaded eradication by vaccines and therapeutic approaches. TB is a global public health problem that kills 1.4 million people per year. The past decade has seen significant progress in developing new vaccine candidates, but the most fundamental questions in understanding disease progression and protective host responses that are responsible for controlling Mtb infection still remain poorly resolved. Current TB treatment requires intense chemotherapy with several antimicrobials, while the only approved vaccine is the classical viable whole-cell based Bacille-Calmette-Guerin (BCG) that protects children from severe forms of TB, but fails to protect adults. Taken together, there is a growing need to conduct basic and applied research to develop novel vaccine strategies against TB. This review is focused on the discussion surrounding current strategies and innovations being explored to discover new protective antigens, adjuvants, and delivery systems in the hopes of creating an efficacious TB vaccine.
MANET secure key exchange using spraying diffie-hellman algorithm

With the proliferation of smart devices such as PDAs, smartphones and tablets having WIFI capabilities, applications orchestrating massive mobile ad-hoc networks (MANETs) are under active development. These networks would have the ability of running communications without the use of pre-existing infrastructure, allowing for a reduction of cost to carriers, setting up communication networks where no infrastructure is available, etc. For such utilities to be widespread, they must take into account the security of data transferred within. In this paper we propose an algorithm that will provide for a secure key exchange during conversation hand-shake, on which a secure channel can built upon. The algorithm assumes no prior knowledge and no user intervention, by using the inherent fluctuation of network topology in MANETs to allow for the discovery of an eavesdropper (if one exists).
Effect of folate and cobalamin compounds on the deoxyuridine suppression test in vitamin B12 and folate deficiency.

In vitro, deoxyuridine (dU) failed to block the incorporation of 3H-thymidine into bone marrow from 11 cases of vitamin B,2 deficiency, 6 cases of folate deficiency, an'i 3 cases of combined deficiency, even in patients without overt anemia, macro- cytosis, and/or megaloblastosis. Different folate and cobalamin compounds had different effects on the incorporation of 3H-thymidine in the two deficiencies. In folate deficiency, the suppressive effect of dU became normal with all the folate forms tested (folic acid, formyltetrahydro- folate, and methyltetrahydrofolate), while I T IS NOW CLEARthat vitamin B,2 deficiency causes a profound dis- turbance of folate metabolism. The finding of high serum folate concentra- tions"2 and low erythrocyte folate3 in patients with vitamin B,2 deficiency has led to the well-known "methylfolate trap" hypothesis proposed by Noronha and Silverman4 and Herbert and Zalusky.2 Since vitamin B12 is needed as the coenzyme of methyltetrahydrofolate homocysteine methyltransferase, it has been suggested that in vitamin B,2 deficiency there is an accumulation of N5- methyltetrahydrofolate (N5-CH3-THF) which leads to a depletion in cells of the other forms of folate that are active in nucleic acid synthesis. The validity of the methylfolate trap has been questioned.5 � However, many of the distur- bances of folate metabolism found in vitamin B,2 deficiency can be explained by the trap hypothesis.8'9 The accumulation of N5-CH3-THF in cobalamin de- ficiency'#{176} and the effect of methionine in preventing the irreversible formation of methyltetrahydrofolate" are consistent with the theory. Other disturbances of folate metabolism in vitamin B,2 deficiency, such as decreased transport of N5-CH3-THF into cells'2 4 and decreased content and synthesis of intracellular pteroylpolyglutamates,'5�'8 do not exclude the methylfolate trap. Deranged DNA synthesis in vitamin B,2 deficiency has been shown by de- fective suppression of the incorporation of tritiated thymidme (3H-TdR) into
Coherence of illness representations in early-stage dementia: an exploratory study using the framework of Leventhal’s common sense self-regulation model

The Common Sense Model of Self-Regulation of Health and Illness has previously been applied to people with early-stage dementia. This suggests that people hold ‘illness representations’ of cognitive perceptions of their health condition. Illness representations develop from lay knowledge, current experience and information from external sources. Recent studies have highlighted that people with early-stage dementia have unmet information needs and require individually tailored information about aspects of dementia which are important to them. Professionals require a way to identify what people with early-stage dementia feel they do not understand about their dementia. Thus, the current study investigated whether illness representations might provide a mechanism for identifying the information needs of eight people with early-stage Alzheimer’s or mixed dementia attending a National Health Service memory clinic. An important feature of illness representations is whether they allow someone to form a coherent understanding of their condition, the ‘coherence’ of their illness representation. For the current study, the definition of coherence was adapted to match research aims, allowing the investigation of particular aspects of dementia people felt they did not understand using semi-structured interviews. A novel feature of this approach was using explicit prompts about what participants felt they understood or did not understand about each area of their illness representation to help illustrate how lack of understanding could contribute to absence of coherence. Interview transcripts were subject to framework analysis which showed that participants could identify things which they did not understand about their dementia and aspects of dementia they would like to know more about. Broad areas of dementia were identified which several people wanted to know about, along with idiosyncratic information needs. For some participants, illness representations, informed by medical stereotypes, appeared to limit their awareness of possible psychosocial support. Strengths, limitations and recommendations for research and practice were discussed.
Dietary predictors of visceral adiposity in overweight young adults

The purpose of the present study was to determine the dietary predictors of visceral adipose tissue (VAT) area in overweight young adults. A total of 109 young adults (fifty males and fifty-nine females) ate ad libitum in a university cafeteria for 14 d. All food and beverages consumed in the cafeteria were measured using observer-recorded weighed plate waste. Food consumption outside the cafeteria (i.e. snacks) was assessed by multiple-pass 24 h recall procedures. VAT was determined using computed tomography. Stepwise regression demonstrated that the best predictor of visceral adiposity in women was total dietary fat (P ≤ 0·05). In men, the model for predicting visceral adiposity included Ca and total dietary fat. We concluded that total dietary fat is the best predictor of VAT area in both men and women. While this relationship was independent in women, in men there was a synergistic relationship between dietary fat consumption and Ca consumption in predicting VAT.
Intimate Partner Violence, Military Personnel, Veterans, and Their Families

Communities throughout the country are grappling with the aftermath of the protracted wars in Iraq (Operation Iraqi Freedom) and Afghanistan (Operation Enduring Freedom) and how to serve military personnel, veterans, and their families effectively with sensitivity to the experiences they have had and the issues they face. This article begins with a discussion of bringing a contextual analysis to the understanding of intimate partner violence (IPV) and how IPV may or may not overlap with potential co-occurring combat-related conditions such as posttraumatic stress disorder, traumatic brain injury, substance use disorder, and depression. Elements of risk and danger, especially in relationship to IPV, these co-occurring conditions, and suicide are also addressed. Implications for family court personnel start with effective methods for screening and assessment within the framework of the larger contextual analysis. The article provides tips for family court personnel by addressing the larger context, applying effective screening/assessment strategies, and utilizing resources available within the military, Veterans' Health Administration, and community settings. Key Points for the Family Court Community * Understand how the larger context in which intimate partner violence is embedded affects risk, danger, and treatment/intervention. * Be able to discuss the intersection of intimate partner violence and co-occurring combat-related conditions such as posttraumatic stress disorder, traumatic brain injury, substance use disorder, and depression and how to approach screening, assessment, and treatment/intervention. * Understand the importance of screening and assessing for intimate partner violence and co-occurring combat-related conditions when making decisions in family court involving military and veteran families.

A Field Validated Model of a Vanadium Redox Flow Battery for Microgrids

The vanadium redox flow battery (VRB) is well-suited for applications with renewable energy devices. This paper presents a practical analysis of the VRB for use in a microgrid system. The first part of the paper develops a reduced order circuit model of the VRB and analyzes its experimental performance efficiency during deployment. The model parameters of the various VRB system components were estimated from experimental field data. The parasitic losses of the circulation pumps power consumption were predicted during different operating situations. The second part of the paper addresses the implementation issues of the VRB application in a photovoltaic-based microgrid system. Commercially available chargers designed for lead-acid battery systems were shown to be non-optimal for VRB systems and a new dc-dc converter control was proposed to provide improved charging performance. The system model was validated with field-obtained experimental data.
Rapid Prototyping Technologies In Prosthetic Dentistry

Background: Recently, rapid prototyping technology is the future of quick and direct production. This technology found applications with metal framework of fixed partial dentures, framework of removable partial dentures, facial prostheses and titanium implants in prosthetic dentistry. Laser beam sintered the selected areas on the alloy powders and the restoration is produced layer by layer at single stage. Purpose: This literatures compared the internal fit, accuracy, bond strength, marginal adaptations, connection between the veneer porcelain, fracture strength marginal and internal gaps of laser-sintered dental prosthesis with conventional casting techniques. Materials and Methods: PubMed and Google scholar electronic database search from 2007 to January 2017 was reviewed. 103 studies were first reviewed by abstract and subsequently by full-text reading. Results: The literature discuss the advantages and disadvantages of laser sintering method from different aspects. They found that internal fit, marginal adaptations, Accuracy of laser-sintered metal restoration are better than that obtained with the traditional casting techniques. In another hand, no difference was observed in the study of internal adaptations, connection between the veneer porcelain, internal gap and porcelain surface treatments between laser sintered and conventional casted metal restoration. Immediate implant loading could be achieved in a reasonable operative time. Conclusions: Laser sintering seems to be an alternative technique to conventional casting of dental alloys. Complex shapes from metal alloys can easily be produced with these devices. These systems can be helpful to obtained fixed restorations, facial prostheses, titanium implants, surgical models and stents. The new laser-sintering technique appears promising for dental application, but additional studies of properties of laser sintered.
Combining Clues for Word Alignment

In this paper, a word alignment approach is presented which is based on a combination of clues. Word alignment clues indicate associations between words and phrases. They can be based on features such as frequency, part-of-speech, phrase type, and the actual wordform strings. Clues can be found by calculating similarity measures or learned from word aligned data. The clue alignment approach, which is proposed in this paper, makes it possible to combine association clues taking different kinds of linguistic information into account. It allows a dynamic tokenization into token units of varying size. The approach has been applied to an English/Swedish parallel text with promising results.

This core is a component-based, distributed and configurable software framework. The presentation discusses both the design and the current implementation. The design separates the structure of the control system from its functionality. Its hard real-time core provides a generic control structure, with plug-in facilities for customization.
Feeling like a group member : social identity, group-based appraisals and group-based emotions

The general idea developed in this thesis is that emotions can not only be individual, but also group-based. We define group-based emotions as emotional reactions to group concerns. Theoretically, we argue that (1) people belong to groups because they depend on the group for certain advantages and therefore should be sensitive to the group’s situation to the extent that the group is important to them, (2) the most fundamental characteristic of individual emotions is that they result from an evaluation or appraisal of the environment in light of the individual’s concerns, and (3) the combination of these two ideas suggests that there is a process of group-based emotional appraisal in which people evaluate the environment in lights of the group’s concerns, i.e. people make group-based appraisals and feel group-based emotions. Seven studies provide empirical support for the role of group-based appraisal in group-based emotion. Three studies show that temporarily increasing the salience of a particular group identity increases appraisals and emotions on behalf of that group. Two follow-up studies confirm this finding using a spontaneous (open-ended) measure of group-based appraisals. Two other studies show that when feelings of social exclusion are induced, people engage more in group-based appraisal, in an apparent attempt to affiliate with group members. We also explore some consequences of the importance of group-based appraisal for group-based emotion. First, we criticize recent conceptualizations of so-called chronic group emotions, and show that these are emotions about group membership (i.e., belonging emotions) rather than emotions because of group membership (i.e., group-based emotions). Second, we investigate the possibility that some appraisals and emotions are chronically linked to certain groups. Finally, we discuss the implications of our results for classifications of group-level emotions, ways to measure group-based emotions, the adaptive nature of group-based emotions, and how to change intergroup relations.
Genetic polymorphisms of ESR1 and ESR2 that may influence estrogen activity and the risk of hypospadias.

BACKGROUND The etiology of hypospadias is regarded as a complex disorder with both genetic and environmental contributions. Although alterations in androgen activity have been associated with hypospadias, few associations with estrogen activity have been documented. Here, we assessed genetic polymorphisms in estrogen receptor genes and their association with hypospadias. METHODS Using a case-control study of 59 cases with hypospadias and 286 controls, we examined the association of hypospadias with the following polymorphisms: PvuII and XbaI in ESR1, and 2681-4A>G in ESR2. RESULTS For the cases, we found a negative association with the G allele containing variants of ESR1 XbaI (OR = 0.52, P < 0.05), and a negative association with the G allele containing variants of ESR2 2681-4A>G (OR = 0.59, P < 0.05). For the cases, we also identified a negative association with the CG haplotype, and a positive association with the CA haplotype, defined by ESR1 PvuII and XbaI (P < 0.05). CONCLUSIONS These findings suggest that the G allele containing variants of ESR1 XbaI and the G allele containing variants of ESR2 2681-4A>G may decrease the risk of hypospadias, whereas the ESR1 C-A haplotype may increase its risk.
Implementation Of Zero Knowledge Protocol I n Wireless Sensor Network for Identification Of Various Attacks

— Wireless Sensor networks (WSN) is excellent technology which provide great potential for situations like battlefields and commercial applications such as building, traffic survey, monitoring environments smart homes and many more scenarios. Security is the most important challenge in wireless sensor networks. Sensor networks dose not haves any user control for each individual node and wireless environment. Basically some special security threats and attacks of WSNs get addressed in our paper. Distributed sensor cloning attack will get identified using this model. We implement zero knowledge protocol (ZKP) for the verification of sender sensor nodes. W i t h attachment of unique fingerprint to each node we addresses the clone attack. In the wireless sensor network non transmission of crucial cryptographic information is addressed by our model using ZKP. So it is helpful for preventing man-in-the middle attack and replay attack. Detailed information about different scenarios and also analysis of performance and cryptographic strength are content of this paper.
