Two side Impedance Matching for Maximum Wireless Power Transmission

The research on high efficient non radiant wireless power transmission (WPT) system using high quality factor resonant coupled coils has become remarkable for powering various portable household devices, biomedical implants, and electrical vehicles since last decade. Therefore, practical WPT must be able to support complicated coil configurations and keep following magnetic resonant conditions with maximum power transfer capability during coupling distance variation. In this paper, an adaptive two side impedance matching technique using self tuned L matching circuits at both the transmitting and receiving sides is proposed for maximizing transmission efficiency in resonant coupled WPT system. The tuning value of inductance and capacitance for matching networks are derived based on the Q based design principle, and extracted impedance ratios and S parameters. The feasibility of the theoretical model is testified against simulation and measured data. The developed model shows that using two side matching technique maximizes transmission efficiency over 80% for a range of 15 35 cm. The proposed technique also successfully retains the resonant frequency and is much more potential to provide maximum efficiency for the resonant coupled WPT system.
Context Specific Lexicon for Hindi Reviews

In the era of social networking, immense amount of posts, comments and tweets generated every second are increasing the size of social database. The analysis of this voluminous data is necessary for exploring the orientation of people's opinion about a particular entity. Most of the online data are in English language, but due to increase in technology and improved awareness of people, the online data available in Indian languages are gradually increasing. Sentiment analysis of English language alone is not sufficient to know the inclination of people towards an entity, other Indian language sentiment analysis is a must, their contribution is also important for us. The available sentiment classification lexicon resources like Hindi SentiWordNet are generic in nature and hence results in average sentiment classification accuracy due to contextual dependency. To improve the sentiment classification accuracy, we present an improvised lexicon resource for Hindi language for Hotel and Movie domains. The improvised polarity lexicon has been built reflecting context sensitivity and to increase coverage it has been expanded used synonyms based approach. The built polarity lexicon resource showcases an improvement in accuracy of 42% and 78% in Movie and Hotel domain, respectively, compared to the existing Hindi SentiWordNet lexicon resource.
Big Business in a Thin Market: Understanding the Privatization of Residential Care for Children and Youth in Sweden

This article analyzes the transformation of Swedish residential care homes for children from a regionally coordinated, public social service system into a thin, but highly profitable, national spot market in which large corporations have a growing presence. Marketization and privatization are theorized as complex processes, through which the institutional structure and logics of this small, but significant, social policy field changed profoundly. Using official documents, register data, media reports and existing research, three consecutive phases in the development of the children's home market are identified since the early 1980s. Change was driven on one hand by policies inspired by New Public Management, which shifted public authority horizontally to the private sector, and vertically to local authorities (funding) and to the state (regulation) On the other hand were responses of local authorities and private actors to the changing incentives that policy shifts entailed. During the first two phases, both the proportion and size of for profit providers increased, and the model of family like care was replaced by a professional model. Cutting across the trend of privatization in the third phase was establishment of a parallel system of homes for unaccompanied refugee children mostly in public ownership. Similarities with privatization in the English system of children's care homes are noted. By showing how the Swedish market for residential care has been created by policy and by actors' responses to those reforms, the article provides a foundation for thinking through how the predictable, significant and well documented problems of such care markets might be addressed.

Temperature Responsive Nanofibrillar Hydrogels for Cell Encapsulation.
Venue: Biomacromolecules

Natural extracellular matrices often have a filamentous nature, however, only a limited number of artificial extracellular matrices have been designed from nanofibrillar building blocks. Here we report the preparation of temperature responsive nanofibrillar hydrogels from rod shaped cellulose nanocrystals (CNCs) functionalized with a copolymer of N isopropylacrylamide and N,N' dimethylaminoethyl methacrylate. The composition of the copolymer was tuned to achieve gelation of the suspension of copolymer functionalized CNCs at 37 degC in cell culture medium and gel dissociation upon cooling it to room temperature. The mechanical properties and the structure of the hydrogel were controlled by changing copolymer composition and the CNC to copolymer mass ratio. The thermoreversible gels were used for the encapsulation and culture of fibroblasts and T cells and showed low cytotoxicity. Following cell culture, the cells were released from the gel by reducing the temperature, thus, enabling further cell characterization. These results pave the way for the generation of injectable temperature responsive nanofibrillar hydrogels. The release of cells following their culture in the hydrogels would enable enhanced cell characterization and potential transfer in a different cell culture medium.
Infantile generalized hypertrichosis caused by topical minoxidil*
Venue: Anais brasileiros de dermatologia

Rare cases of hypertrichosis have been associated with topically applied minoxidil. We present the first reported case in the Brazilian literature of generalized hypertrichosis affecting a 5 year old child, following use of minoxidil 5% 20 drops a day, for hair loss. The laboratory investigation excluded hyperandrogenism and thyroid dysfunction. Topical minoxidil should be used with caution in children.
Efficacy and Safety of Minoxidil 2% Solution in Combination With a Botanical Hair Solution in Women With Female Pattern Hair Loss/Androgenic Alopecia.
Venue: Journal of drugs in dermatology JDD

Female pattern hair loss (FPHL) also known as female androgenic alopecia, affects over 21 million women in the United States with devastating effects on self esteem and psychosocial functioning. Topical minoxidil 2% and 5% formulations are the only US Food and Drug Administration approved treatments for FPHL. The length of time it typically takes to observe the benefits is a challenge for many patients, and may affect adherence to treatment. Herbal extracts, which are also believed to promote healthier looking hair, have a long history of use in hair care formulations. The safety and efficacy of a twice daily regimen of 2% minoxidil solution used in combination with the botanical hair solution for 12 weeks in 54 subjects was evaluated in a multicenter, single arm, open label study. Assessments included investigator and subject ratings of improvement and subject satisfaction. Investigator ratings indicated significant improvement in hair growth and overall treatment benefits in as early as 6 weeks (P<.001) Subject self ratings indicated significant satisfaction with hair volume and quality improvement at week 6 (P<.001) Subjects also indicated an increase in self confidence and attractiveness at week 12 (P<.001) The investigator and subject assessed efficacy and subject satisfaction with this regimen provides clinicians with an effective treatment option for FPHL that also provides a high level of patient acceptance, which ultimately may help promote minoxidil treatment adherence.
A NEW PERSPECTIVE FOR THE TREATMENT OF DANDRUFF ASSOCIATED ALOPECIA WITH EMULSION BASED GEL CONTAINING KETOCONAZOLE AND MINOXIDIL

Many antifungal drugs are used topically in order to treat fungal diseases. Among them Ketoconazole is used widely among these topical antifungal drugs for eradication of dandruff. Scalp with dandruff causes more hair fall than normal scalp and hair fall is treated by topical Minoxidil formulation. Aim of present work is to prepare a topical formulation containing both ketoconazole and minoxidil in order to treat dandruff and associated diffused alopecia simultaneously. Both the drugs are incorporated in emulgel at a particular step in order to prepare formulation. Emulgel i.e. emulsion in gel have been emerged out as one of the most beneficial topical drug delivery system as it contain both hydrophilic and lipophilic drugs with dual controlled release system i.e. emulsion and gel. Incorporation of emulsion in gel also increases the stability of emulsion. Emulgel was prepared by using carbopol 934 as gelling agent. The influence of concentration of gelling agent and emulsifying agent on the drug release from the prepared emulgel was investigated using a 2x2 2 factorial design. The prepared emulgel were evaluated for their physical appearance, viscosity, pH, spreadability, drug content and drug release. All the prepared emulgel showed acceptable physical properties concerning color, homogeneity, consistency, spreadability and pH value. The highest release was observed with Formulation F8 (92.65+ 0.08 for Ketoconazole and 97.63+ 0.27 for Minoxidil) and lowest with Formulation F1 (31.39+ 0.28 for Ketoconazole and 40.66+ 0.19 for Minoxidil) Since we need lowest Ketoconazole release in circulation and highest deposition in skin for dandruff eradication, hence Formulation F1 was further evaluated for drug deposition in rat skin via indirect method and 41.62 of Ketoconazole and 15.83 of minoxidil was observed. Thus this formulation can be used for simultaneous treatment of dandruff and associated diffused alopecia for better patient compliance.  Dandruff is a common scalp disorder which affects both male and female population. It is a common complaint among half of the population of the world.
Treatment of monilethrix with oral minoxidil
Venue: JAAD case reports

Monilethrix is an autosomal dominant genodermatosis characterized by hair fragility, keratosis pilaris, and pathognomonic beading of the hair shaft. Hair fragility may lead to hair breakage and the appearance of generalized hair  The gene for autosome dominant monilethrix has been mapped to the epithelial keratin gene cluster on 12q13,2 and point mutations have been found in the hair cortex specific keratin genes KRT86, KRT83, and KRT81.3, 4 Mutations in desmoglein 4 are responsible for an autosomal recessive variant of monilethrix.5 Monilethrix has considerable inter and intrafamilial variations in age of onset, severity, and natural history.4 Most often, hair is normal at birth and is progressively replaced by short, fragile, brittle hair during the first months of life. Hair breakage secondary to hair fragility may be accompanied by follicular keratosis most commonly on the occiput. Friction from wigs and their adhesives may exacerbate hair loss. Eyebrows, eyelashes, pubic, axillary, and general body hair may be affected along with the scalp. In most patients, the hair loss persists with little change throughout life. Spontaneous improvement or complete recovery has been reported during pregnancy.6 There is no cure for monilethrix. Reduction in hairdressing trauma may diminish weathering and improve severely affected  Two women with monilethrix who responded to 6 months of treatment with low dose oral minoxidil are described.
Chlorhexidine versus Tincture of Iodine for Reduction of Blood Culture Contamination Rates: a Prospective Randomized Crossover Study
Venue: Journal of Clinical Microbiology

Blood cultures (BCs) are the standard method for diagnosis of bloodstream infections (BSIs) However, the average BC contamination rate (CR) in U.S. hospitals is 2.9% potentially resulting in unnecessary antibiotic use and excessive therapy costs. Several studies have compared various skin antisepsis agents without a clear consensus as to which agent is most effective in reducing contamination. A prospective, randomized crossover study directly comparing blood culture contamination rates using chlorhexidine versus iodine tincture for skin antisepsis was performed at Robert Wood Johnson University Hospital (RWJUH) Eight nursing units at RWJUH were provided with blood culture kits containing either chlorhexidine (CH) or iodine tincture (IT) for skin antisepsis prior to all blood culture venipunctures, which were obtained by nurses or clinical care technicians. At quarterly intervals, the antiseptic agent used on each nursing unit was switched. Analyses of positive BCs were performed to distinguish true BSIs from contaminants. Of the 6,095 total BC sets obtained from the participating nursing units, 667 (10.94% were positive and 238 (3.90% were judged by the investigators to be contaminated. Of the 3,130 BCs obtained using IT, 340 (10.86% were positive and 123 (3.93% were contaminated. Of 2,965 BCs obtained using CH, 327 (11.03% were positive and 115 (3.88% were contaminated. The rates of contaminated BCs were not statistically significant between the two antiseptic agents (P 1.0) We conclude that CH and IT are equivalent agents for blood culture skin antisepsis.
Could Topical Minoxidil Cause Non Arteritic Anterior Ischemic Optic Neuropathy?
Venue: Journal of clinical and diagnostic research JCDR

Minoxidil hair formulation is commonly used for the treatment of male or female androgenic alopecia. Minoxidil is a Health Canada and US FDA approved medication for hair loss in men and women. The drug is marketed as 2% and 5% topical solutions. This over the counter product is considered safe, but should be used with caution. Furthermore, minoxidil is an orally active vasodilator for treatment of severe hypertension. Typical side effects of minoxidil are faster heart rate, augmented heart function and stroke volume (which can be associated with reduced vascular resistance upon baroflex stimulus) retained sodium and water and abnormal hair growth. The most common adverse reactions of the topical formulation are limited to irritant and allergic contact dermatitis on the scalp. Herein, we report a non arteritic anterior ischemic optic neuropathy caused by topical 5% minoxidil treatment that was resolved after discontinuation of minoxidil.
High throughput dual colour precision imaging for brain wide connectome with cytoarchitectonic landmarks at the cellular level
Venue: Nature communications

The precise annotation and accurate identification of neural structures are prerequisites for studying mammalian brain function. The orientation of neurons and neural circuits is usually determined by mapping brain images to coarse axial sampling planar reference atlases. However, individual differences at the cellular level likely lead to position errors and an inability to orient neural projections at single cell resolution. Here, we present a high throughput precision imaging method that can acquire a co localized brain wide data set of both fluorescent labelled neurons and counterstained cell bodies at a voxel size of 0.32 x 0.32 x 2.0 mm in 3 days for a single mouse brain. We acquire mouse whole brain imaging data sets of multiple types of neurons and projections with anatomical annotation at single neuron resolution. The results show that the simultaneous acquisition of labelled neural structures and cytoarchitecture reference in the same brain greatly facilitates precise tracing of long range projections and accurate locating of nuclei.
Methodology Considerations in Phase Mapping of Human Cardiac Arrhythmias
Venue: Circulation. Arrhythmia and electrophysiology

Phase analysis of cardiac arrhythmias, particularly atrial fibrillation, has gained interest because of the ability to detect organized stable drivers (rotors) and target them for therapy. However, the lack of methodology details in publications on the topic has resulted in ongoing debate over the phase mapping technique. By comparing phase maps and activation maps, we examined advantages and limitations of phase mapping.  Seven subjects were enrolled. We generated phase maps and activation maps from electrocardiographic imaging reconstructed epicardial unipolar electrograms. For ventricular signals, phase was computed with (1) pseudoempirical mode decomposition detrending and (2) a novel Moving Average (MVG) detrending approach. For atrial fibrillation signals, MVG was modified to incorporate dynamic cycle length (DCL) changes (MVG DCL) Phase maps were visually analyzed to study phase singularity points and rotors. Results show that phase is sensitive to cycle length choice, a limitation that was addressed by the MVG DCL algorithm. MVG DCL was optimal for atrial fibrillation analysis. Phase maps helped to highlight high curvature wavefronts and rotors. However, for some activation patterns, phase generated nonrotational singularity points and false rotors.  Phase mapping computes singularity points and visually highlights rotors. As such, it can help to provide a clearer picture of the spatiotemporal activation characteristics during atrial fibrillation. However, it is advisable to incorporate electrogram characteristics and the time domain activation sequence in the analysis, to prevent misinterpretation and false rotor detection. Therefore, for mapping complex arrhythmias, a combined time domain activation and phase mapping with variable cycle length seems to be the most reliable method.
Mechanisms of Hippo pathway regulation.
Venue: Genes development

The Hippo pathway was initially identified in Drosophila melanogaster screens for tissue growth two decades ago and has been a subject extensively studied in both Drosophila and mammals in the last several years. The core of the Hippo pathway consists of a kinase cascade, transcription coactivators, and DNA binding partners. Recent studies have expanded the Hippo pathway as a complex signaling network with >30 components. This pathway is regulated by intrinsic cell machineries, such as cell cell contact, cell polarity, and actin cytoskeleton, as well as a wide range of signals, including cellular energy status, mechanical cues, and hormonal signals that act through G protein coupled receptors. The major functions of the Hippo pathway have been defined to restrict tissue growth in adults and modulate cell proliferation, differentiation, and migration in developing organs. Furthermore, dysregulation of the Hippo pathway leads to aberrant cell growth and neoplasia. In this review, we focus on recent developments in our understanding of the molecular actions of the core Hippo kinase cascade and discuss key open questions in the regulation and function of the Hippo pathway.
HMOG: New Behavioral Biometric Features for Continuous Authentication of Smartphone Users
Venue: IEEE Transactions on Information Forensics and Security

We introduce hand movement, orientation, and grasp (HMOG) a set of behavioral features to continuously authenticate smartphone users. HMOG features unobtrusively capture subtle micro movement and orientation dynamics resulting from how a user grasps, holds, and taps on the smartphone. We evaluated authentication and biometric key generation (BKG) performance of HMOG features on data collected from 100 subjects typing on a virtual keyboard. Data were collected under two conditions: 1) sitting and 2) walking. We achieved authentication equal error rates (EERs) as low as 7.16% (walking) and 10.05% (sitting) when we combined HMOG, tap, and keystroke features. We performed experiments to investigate why HMOG features perform well during walking. Our results suggest that this is due to the ability of HMOG features to capture distinctive body movements caused by walking, in addition to the hand movement dynamics from taps. With BKG, we achieved the EERs of 15.1% using HMOG combined with taps. In comparison, BKG using tap, key hold, and swipe features had EERs between 25.7% and 34.2% We also analyzed the energy consumption of HMOG feature extraction and computation. Our analysis shows that HMOG features extracted at a 16 Hz sensor sampling rate incurred a minor overhead of 7.9% without sacrificing authentication accuracy. Two points distinguish our work from current literature: 1) we present the results of a comprehensive evaluation of three types of features (HMOG, keystroke, and tap) and their combinations under the same experimental conditions and 2) we analyze the features from three perspectives (authentication, BKG, and energy consumption on smartphones)
AppScanner: Automatic Fingerprinting of Smartphone Apps from Encrypted Network Traffic
Venue: 2016 IEEE European Symposium on Security and Privacy (EuroS&P)

Automatic fingerprinting and identification of smartphone apps is becoming a very attractive data gathering technique for adversaries, network administrators, investigators and marketing agencies. In fact, the list of apps installed on a device can be used to identify vulnerable apps for an attacker to exploit, uncover a victim's use of sensitive apps, assist network planning, and aid marketing. However, app fingerprinting is complicated by the vast number of apps available for download, the wide range of devices they may be installed on, and the use of payload encryption protocols such as HTTPS/TLS. In this paper, we present a novel methodology and a framework implementing it, called AppScanner, for the automatic fingerprinting and real time identification of Android apps from their encrypted network traffic. To build app fingerprints, we run apps automatically on a physical device to collect their network traces. We apply various processing strategies to these network traces before extracting the features that are used to train our supervised learning algorithms. Our fingerprint generation methodology is highly scalable and does not rely on inspecting packet payloads, thus our framework works even when HTTPS/TLS is employed. We built and deployed this lightweight framework and ran a thorough set of experiments to assess its performance. We automatically profiled 110 of the most popular apps in the Google Play Store and were later able to re identify them with more than 99% accuracy.
