Design, Development and Optimization of Highly Efficient Solar Cars: Gato del Sol I-IV

- Engineering students at the University of Kentucky have designed and built solar powered cars for the 2008 North American Solar Challenge and the 2009 Formula Sun Grand Prix. Gato del Sol III, our most accomplished car, is powered by a solar array of 480 Silicon monocrystalline photovoltaic cells. Maximum Power Point trackers efficiently made use of these cells and tracked the perfect load. The cells are mounted on a fiber glass and foam core composite shell. The shell rides on a lightweight aluminum tube chassis, which is then powered by a 90% efficient brushless DC motor. Gato del Sol IV will be one of the fastest solar powered cars in the world with a top speed of 75mph. Internally, the car makes use of 168 high density lithium-polymer batteries to account for a 5kWh pack, enough to travel over 75 miles without sun. A homebuilt battery protection system and charge balancing system ensures safe and efficient use of the batteries. Various electrical sub-systems on the car communicate between themselves via Controller Area Network (CAN). This real time data is then transmitted to an external computer via RF communication for further analysis and on the fly improvements. Gato del Sol IV is building on the team's previous successes including a 2nd place finish at the 2009 Formula Sun Grand Prix beating teams from top ranked schools from across the globe. The team continues to promote awareness about smarter and greener technologies to K-12 students throughout the Commonwealth of Kentucky. Many educational tours and forums are organized to the same end in elementary, middle, and high schools around the state.

Money and Marriage

Many couples fight about money, but there is little theory available in the professional literature to guide research or clinical activities. This paper explores power, commitment, trust, esteem, control and identity issues that surface in marital discord over money. It is suggested that marital problems over money are a transparency into the core dynamics of the relationship.
Vascular Biology and Medicine in the 1990s: Scope, Concepts, Potentials, and Perspectives

V ascular disease is the leading cause of mortality and morbidity in the United States. Coronary artery disease, cerebrovascular disorders, pulmonary venous thromboembolism, and systemic and pulmonary hypertension account for one third of the national annual mortality. Traditionally, the practice of cardiology has emphasized the diagnosis and treatment of the sequelae of these disorders. This approach has been exemplified by major advances in cardiovascular surgery, interventional catheter techniques, and heartlung transplantations, to name a few. Recently, major conceptual shifts have occurred in our approach to vascular disease. Increasingly, we recognize the importance of preventive cardiology and the need to understand the fundamental mechanisms mediating these disorders. Specifically, there is an explosion of new information on the complex and intricate processes that maintain homeostasis of the vessel wall and the pathobiological events that result in vascular diseases. We believe that the future in the management of vascular disease will depend on the development of novel diagnostic and therapeutic strategies based on our growing knowledge of vascular biology. This article is intended to review the latest developments in vascular biology and provide our perspectives on the future of the emerging discipline of vascular medicine. The concept of vascular biology and medicine has evolved dramatically from William Harvey's1 original description of the circulation in which the vasculature was conceived as a passive conduit transporting blood to and from vital organs. It is now recognized that the vasculature is a complex organ capable of sensing its environment, transducing signals to the cells within the vasculature or to the surrounding tissue, and synthesizing local mediators that promote functional or structural responses. A constant feature of these interactions is the delicate balance between countervailing mechanisms. Vascular cells produce vasoconstrictors as well as vasodilators, procoagulants as well as anticoagulants,
Fettsäurekonzentrationen bei depressiven Patienten im Verlauf einer repetitiven transkraniellen Magnetstimulation (rTMS)

Zusammenfassung Bei Patienten mit depressiven Störungen werden Dysbalancen von Omega-3– und Omega-6-Fettsäuren (FS) diskutiert. Studienergebnisse wiesen einen antidepressiven Effekt einer repetitiven transkraniellen Magnetstimulation (rTMS) nach. Ziel unserer Studie war, die FS-Konzentrationen im Verlauf einer rTMS bei depressiven Patienten und Zusammenhänge zwischen Schweregrad der Depressivität und FS-Mustern zu ermitteln. Hierzu wurden 30 Patienten mit einer Depression in eine doppelblinde Plazebo-kontrollierte Studie eingeschlossen, erhielten entweder eine hochfrequente rTMS über dem linken, eine niedrigfrequente rTMS über dem rechten dorsolateralen präfrontalen Kortex oder eine Scheinbehandlung über einen Zeitraum von 10 Tagen. Vor und nach der Behandlungsserie wurden der Schweregrad der Depressivität, die psychomotorische Beeinträchtigung sowie die Serum-Konzentrationen der mehrfach ungesättigten FS analysiert. Während sich der Schweregrad der Depressivität in allen Gruppen besserte, war die psychomotorische Beeinträchtigung nur nach den realen rTMS-Formen rückläufig. Nach der hochfrequenten rTMS zeigte sich zusätzlich ein signifikanter Anstieg des FSQuotienten, während dies nach den anderen rTMS-Formen nicht der Fall war. Die Wertigkeit der FS-Konzentrationen als Marker für den Behandlungserfolg im Rahmen einer Depression wird diskutiert.
Intruder detector: A continuous authentication tool to model user behavior

This paper presents techniques to continuously authenticate users as they interact with web-based software. Unique behavioral footprints, indicating patterns of use for groups of users, are captured from web server log files and integrated into an n-gram model. These statistical language models provide sequences and sub-sequences of user interaction, ordering, and temporal relationships. When users interact with web-based software, their stored usage profile is compared to their current interactions. Deviations may indicate malicious activity. We use our innovative tool, Intruder Detector (ID) to generate the profiles. Afterwards, we use various measures-of-effectiveness techniques to understand the feasibility of our approach. Our empirical study shows that session length and the prevalence of user data significantly affect the model's ability to correctly classify users.
Der Depression die Stirn bieten – mit Botulinumtoxin

Zusammenfassung Gegenstand und Ziel: Nach Behandlung der Glabellafalte mit Botulinumtoxin A (BoNT) in einer offenen Fallserie ist es bei Patientinnen, die an einer Depression litten, zu einer Besserung oder Remission der Depression gekommen. Mit der hier vorgestellten randomisierten, kontrollierten Studie soll die Frage beantwortet werden, ob eine adjuvante BoNTBehandlung der Glabellafalte einen positiven Effekt auf die Depression zeigt. Methodik: Es wurden je 15 Patienten in die Verum(BoNT) oder in die Placebogruppe randomisiert. Primärer Endpunkt war die Veränderung auf der 17-Item-Version der Hamilton-Depressionsskala (Ham-D17) sechs Wochen nach der BoNT-Injektion, zudem wurde der Beck-Depressionsinventar (BDI) und die Clinical Global Impression (CGI) erhoben. Ergebnisse: Über die 16-wöchige Beobachtungszeit kam es in der Verumgruppe zu einer signifikanten Besserung der Symptome der Depression (Ham-D17, F = 5,76, p < 0,001, η2= 0,17). Sechs Wochen nach einer einmaligen Behandlung waren die Ham-D17-Werte bei den mit BoNT behandelten Studienteilnehmern im Schnitt um 47,1% und bei denen in der Placebogruppe um durchschnittlich 9,2% gesunken (F = 12,30, p = 0,002, η2 = 0,31, d = 1,28). Die klinische Verbesserung spiegelte sich in gleicher Weise im BDI und in der CGI wider. Schlussfolgerung: Diese Studie zeigt, dass eine einmalige Behandlung der Glabellaregion mit BoNT als adjuvante Therapie bei Patienten mit Depression zu einer rasch einsetzenden, ausgeprägten und lang anhaltenden Besserung der Depression führen kann. Sie unterstützt die Facial-Feedback-Theorie, gemäß der die Mimik nicht nur Stimmung ausdrücken, sondern auch regulieren kann.
SCHOOL CHOICE, EQUITY AND SOCIAL JUSTICE: THE CASE FOR MORE CONTROL

ABSTRACT: This paper focuses on school choice and the extent to which admissions to publicly-funded secondary schools in England address issues of equity and social justice. It argues that schools with responsibility for their own admissions are more likely than others to act in their own self interest by ‘selecting in’ or ‘creaming’ particular pupils and ‘selecting out’ others. Given this, it is argued that individual schools should not be responsible for admissions. Instead, admissions should be the responsibility of a local authority (or non-partisan body); this body should make decisions about who should be allocated to which school on the basis of the expressed wishes of the parents, and the admissions criteria of the school in question. Admissions criteria should be objective, clear and fair and the admissions system itself should address issues of equity and social justice. It is argued that systems where there are some ‘controls’ on the choice process should be facilitated to address equity and social justice considerations which can benefit individuals and communities.
Dynamic Pricing with an Unknown Linear Demand Model : Asymptotically Optimal Semi-myopic Policies

We consider a monopolist who sells a set of products over a time horizon of T periods. The seller initially does not know the parameters of the products’ linear demand curve, but can estimate them based on demand observations. We first assume that the seller knows nothing about the parameters of the demand curve, and then consider the case where the seller knows the expected demand under an incumbent price. It is shown that the smallest achievable revenue loss in T periods, relative to a clairvoyant who knows the underlying demand model, is of order √ T in the former case and of order logT in the latter case. To derive pricing policies that are practically implementable, we take as our point of departure the widely used policy called greedy iterated least squares (ILS), which combines sequential estimation and myopic price optimization. It is known that the greedy ILS policy itself suffers from incomplete learning, but we show that certain variants of greedy ILS achieve the minimum asymptotic loss rate. To highlight the essential features of well-performing pricing policies, we derive sufficient conditions for asymptotic optimality.
Estrogen-Mediated, Endothelial Nitric Oxide Synthase–Dependent Mobilization of Bone Marrow–Derived Endothelial Progenitor Cells Contributes to Reendothelialization After Arterial Injury

Background—We hypothesized that estrogen-induced acceleration of reendothelialization might be mediated in part by effects involving mobilization and incorporation of bone marrow–derived endothelial progenitor cells (EPCs). Methods and Results—Carotid injury was induced in ovariectomized wild-type mice receiving either 17&bgr;-estradiol or placebo. Estradiol treatment significantly accelerated reendothelialization of injured arterial segments within 7 days and resulted in a significant reduction of medial thickness 14 and 21 days after the injury. Significant increases in circulating EPCs 3 days after the injury were observed in the estradiol group compared with placebo-treated mice. These data were further supported by fluorescence-activated cell sorting analysis, which disclosed a significant increase in Sca-1/Flk-1–positive cells in estradiol versus control mice. To evaluate the effects of estradiol on bone marrow–derived EPC incorporation at sites of reendothelialization, carotid injury was established in ovariectomized wild-type mice transplanted with bone marrow from transgenic donors expressing &bgr;-galactosidase transcriptionally regulated by the Tie-2 promoter. Significantly greater numbers of X-gal–positive cells were observed at reendothelialized areas in the estradiol group 3 days after injury as compared with placebo. Fluorescent immunohistochemistry 14 days after the injury documented a marked increase in cells expressing both &bgr;-gal, indicating bone marrow origin and Tie-2 expression, and isolectin B4, also indicating endothelial lineage, in the estradiol group compared with control. In contrast, estradiol did not accelerate reendothelialization or augment EPC mobilization into the peripheral circulation after injury in endothelial nitric oxide synthase–deficient mice (eNOS−/−). Furthermore, estradiol exhibited direct stimulatory effects on EPC mitogenic and migration activity and inhibited EPC apoptosis. Conclusions—Estradiol accelerates reendothelialization and attenuates medial thickening after carotid injury in part by augmenting mobilization and proliferation of bone marrow–derived EPCs and their incorporation into the recovering endothelium at the site of injury.
Perceive EEmotion from facial expressions

Humans are trying to interact with the computer via touch screen, smart-phones, audio and video. A computer get information from the human via an interface and likewise, a human recognize an information from the computer via an interface. Facial expression recognition is a key element in a human communication. In order to promote the man and machine interaction, a framework is proposed for the facial expression recognition from the images. The approach for representing the facial parts was done by Haar-Like features and the learning of these features was made possible by AdaBoost algorithm. Several application scenarios were proposed in terms of the feature extraction and emotion detection. As this system is capable of detecting the emotions from the images stored in a database, is going further here in this paper, an efficiency of emotion detection is giving the better response in terms of the time. The experimental results represents that, the proposed approach has the capability of detecting the false acceptance rate is 18% while the false rejection rate is just 5%.
British Rule and Tribal Revolts in India: The curious case of Bastar*

Abstract British colonial rule in India precipitated a period of intense rebellion among the country's indigenous groups. Most tribal conflicts occurred in the British provinces, and many historians have documented how a host of colonial policies gave rise to widespread rural unrest and violence. In the post-independence period, many of the colonial-era policies that had caused revolt were not reformed, and tribal conflict continued in the form of the Naxalite insurgency. This article considers why the princely state of Bastar has continuously been a major centre of tribal conflict in India. Why has this small and remote kingdom, which never came under direct British rule, suffered so much bloodshed? Using extensive archival material, this article highlights two key findings: first, that Bastar experienced high levels of British intervention during the colonial period, which constituted the primary cause of tribal violence in the state; and second, that the post-independence Indian government has not reformed colonial policies in this region, ensuring a continuation and escalation of tribal conflict through the modern Naxalite movement.
An Attenuating Mutation in nsP1 of the Sindbis-Group Virus S.A.AR86 Accelerates Nonstructural Protein Processing and Up-Regulates Viral 26S RNA Synthesis

ABSTRACT The Sindbis-group alphavirus S.A. AR86 encodes a threonine at nonstructural protein 1 (nsP1) 538 that is associated with neurovirulence in adult mice. Mutation of the nsP1 538 Thr to the consensus Ile found in nonneurovirulent Sindbis-group alphaviruses attenuates S.A. AR86 for adult mouse neurovirulence, while introduction of Thr at position 538 in a nonneurovirulent Sindbis virus background confers increased neurovirulence (M. T. Heise et al., J. Virol. 74:4207-4213, 2000). Since changes in the viral nonstructural region are likely to affect viral replication, studies were performed to evaluate the effect of Thr or Ile at nsP1 538 on viral growth, nonstructural protein processing, and RNA synthesis. Multistep growth curves in Neuro2A and BHK-21 cells revealed that the attenuated s51 (nsP1 538 Ile) virus had a slight, but reproducible growth advantage over the wild-type s55 (nsP1 538 Thr) virus. nsP1 538 lies within the cleavage recognition domain between nsP1 and nsP2, and the presence of the attenuating Ile at nsP1 538 accelerated the processing of S.A. AR86 nonstructural proteins both in vitro and in infected cells. Since nonstructural protein processing is known to regulate alphavirus RNA synthesis, experiments were performed to evaluate the effect of Ile or Thr at nsP1 538 on viral RNA synthesis. A combination of S.A. AR86-derived reporter assays and RNase protection assays determined that the presence of Ile at nsP1 538 led to earlier expression from the viral 26S promoter without affecting viral minus- or plus-strand synthesis. These results suggest that slower nonstructural protein processing and delayed 26S RNA synthesis in wild-type S.A. AR86 infections may contribute to the adult mouse neurovirulence phenotype of S.A. AR86.
Cisplatin combination chemotherapy versus chlorambucil in advanced ovarian carcinoma: mature results of a randomized trial.

A randomized study to compare the efficacy of combination chemotherapy (cisplatin, doxorubicin, cyclophosphamide: PACe) with chlorambucil (CB) in International Federation of Gynecology and Obstetrics (FIGO) stage III and IV ovarian carcinoma was conducted between May 1979 and October 1983. Patients failing initial CB were subsequently eligible for treatment with PACe. Eighty-nine patients were randomized and 85 were eligible for analysis; as of date, 72 of these patients have died. The majority of patients in this study had bulky residual disease after their initial laparotomy (76%). Complete response (CR) was documented by a second laparotomy after five cycles of combination therapy or 6 to 12 months alkylating agent therapy. The overall response rate (CR plus partial response [PR]) for the combination (PACe, 68%) was significantly higher (P = .0004) than that for the chlorambucil (CB, 26%). However, the median survival was not improved (PACe, 13 months; CB, 11 months) and the survival curves were not significantly different (log rank test P = .25). The results of this study are comparable to preliminary data reported from other similar randomized studies. PACe, as administered in this study, is not indicated as routine therapy in patients with bulky residual ovarian carcinoma.
The Design of XPRS

1.1. High Performance This paper presents an overview of the techniques we are using to build a DBMS at Berkeley that will simultaneously provide high performance and high availability in transaction processing environments, in applications with complex ad-hoc queries and in applications with large objects such as images or CAD layouts. We plan to achieve these goals using a general purpose DBMS and operating system and a shared memory multiprocessor. The hardware and software tactics which we are using to accomplish these goals are described in this paper and include a novel “fast path” feature, a special purpose concurrency control scheme, a twodimensional file system, exploitation of parallelism and a novel method to efficiently mirror disks. We strive for high performance in three different application areas: 1) transaction processing 2) complex ad-hoc queries 3) management of large objects
Co-production and co-consumption: Perspectives on immigration through a discourse analysis of voters’ blogs in the 2010 General Election

Abstract The issue of immigration proved to be a crucially important flashpoint for all three parties in the 2010 British General Election. In this paper, we focus on a citizen-centred perspective on the 2010 British General Election by analysing the views of the electorate on this pivotal issue in the as blogosphere. Using thematic and discursive analysis, we examine how voters articulate their opinions and concerns on immigration in the blogosphere and how these discursive practices can be studied to enrich political market research. The findings show that a complex issue such as immigration is a dynamic expression of, and between, multiple, competing, contradictory discourses, and interests. As such, the blogosphere provides an invaluable tool for in-depth political market research because it can contribute to a more nuanced understanding of the co-production and co-consumption of current affairs.
Study to compare performance of International HIV dementia scale ( IHDS ) and Hindi mental state examination ( HMSE ) scale in assessing neurocognitive dysfunction among HIV / AIDS patients on antiretroviral therapy

Human immunodeficiency virus (HIV) invades the central nervous system during the primary infection period and often leads to neurological complications that have recently been characterized as HIVassociated neurocognitive disorders (HAND). To better assist in prevention, treatment and management of HAND, it is important to develop and evaluate the neurocognitive screening tools. The main Objective of study was designed to determine the comparative performance of international HIV dementia scale (IHDS) and Hindi mental state examination (HMSE) scale in assessing neurocognitive dysfunction among HIV/AIDS patients on antiretroviral therapy. In methods, a consecutive sample of „80‟ HIV positive patients registered at ART Centre of PBM and AG Hospital, Bikaner were clinically interviewed and administered the IHDS and HMSE scale to assess any neurocognitive dysfunction. The Results were Individuals with HAND showed significantly poor performance in comparison to individuals without HAND. The mean IHDS scores were low in HIV-positive HAND group as compared to HIV-positive individuals without HAND (p<0.05) while there was no significant difference in mean HMSE score between HIV positive HAND group and individuals without HAND (p>0.05). HAND detection rate was found to be significantly high using the IHDS (26/80 i.e. 32.50%) as compared to HMSE scale (2/80 i.e. 2.5%). In Conclusion the present findings indicate that HMSE scale is a weak tool in comparison to IHDS in terms of defining those with and without HAND. The IHDS may be of great value as a screening test for HAND.
Video text detection based on text edge map

Video text often contains highly useful semantic information, the analysis of which can to a great extent facilitate video retrieving and understanding. In this paper, a novel method has been proposed to detect video text. Text character strokes display dense edge features in both horizontal and vertical directions. Therefore the authors create a text edge map on the basis of the Kirsch operators. Then the authors utilize the motion detection mask to sieve the horizontal and vertical text edge map. Finally we detect the video text on the basis of text edge map. Experiments are carried out with video sources of various sizes, languages, colors, fonts, which confirm that the proposed method is robust.
