Leading corrections to local approximations II : The case with turning points

Quantum corrections to Thomas-Fermi (TF) theory are investigated for noninteracting one-dimensional fermions with known uniform semiclassical approximations to the density and kinetic energy. Their structure is analyzed, and contributions from distinct phase space regions (classically-allowed versus forbidden at the Fermi energy) are derived analytically. Universal formulas are derived for both particle numbers and energy components in each region. For example, in the semiclassical limit, exactly 1/(6\pi3^{1/2}) of a particle leaks into the evanescent region beyond a turning point. The correct normalization of semiclassical densities is proven analytically in the semiclassical limit. Energies and densities are tested numerically in a variety of one-dimensional potentials, especially in the limit where TF theory becomes exact. The subtle relation between the pointwise accuracy of the semiclassical approximation and integrated expectation values is explored. The limitations of the semiclassical formulas are also investigated when the potential varies too rapidly. The approximations are shown to work for multiple wells, except right at the mid-phase point of the evanescent regions. The implications for density functional approximations are discussed.
Linguistic diversity in the classroom, student achievement, and social integration

ABSTRACT We analyze whether non-native speakers in the classroom affect students' educational achievement and social integration. In contrast to previous studies, which mainly examine the effect of the share of immigrant pupils, we focus on language heterogeneity by using a novel measure of the degree of linguistic diversity in the classroom. Conditional on the concentration of non-native speakers in the class, the degree of linguistic diversity has no adverse effect on students' language and math skills, but worsens the social integration of non-native speakers. We demonstrate the robustness of these findings in a variety of sensitivity checks.
Cloud screening and quality control algorithm for star photometer data: assessment with lidar measurements and with all-sky images

This paper presents the development and set up of a cloud screening and data quality control algorithm for a star photometer based on CCD camera as detector. These algo- rithms are necessary for passive remote sensing techniques to retrieve the columnar aerosol optical depth, Ae() , and precipitable water vapor content, W , at nighttime. This cloud screening procedure consists of calculating moving averages of Ae() and W under different time-windows combined with a procedure for detecting outliers. Additionally, to avoid undesirable Ae() and W fluctuations caused by the atmo- spheric turbulence, the data are averaged on 30 min. The al- gorithm is applied to the star photometer deployed in the city of Granada (37.16 N, 3.60 W, 680 m a.s.l.; South-East of Spain) for the measurements acquired between March 2007 and September 2009. The algorithm is evaluated with correl- ative measurements registered by a lidar system and also with all-sky images obtained at the sunset and sunrise of the pre- vious and following days. Promising results are obtained de- tecting cloud-affected data. Additionally, the cloud screening algorithm has been evaluated under different aerosol condi- tions including Saharan dust intrusion, biomass burning and pollution events.
Information about basic imaging methods in psychiatric patients : Current methods and advances

Psychiatric disorders account for a great majority of overall health problems. Therefore, psychiatric conditions have become of great importance for today's world. It is a known fact that quality of life is substantially determined by the mental health of an individual. A great number of physical diseases have also important mental component. As its importance has been defined here, psychiatric science has shown considerable change particularly in the second half of the current century, and making a diagnosis has become available not only via physical examination, but also by detecting underlying organic factors. In line with the advances in clinical psychiatry, neuropsychiatry and biologic psychiatry, considerable progression has been achieved both in diagnosis and also in treatment. In this process, structural and functional imaging techniques have remarkably contributed to the etiology of psychiatric diseases to be understood better, as well as to the development of diagnostic approach. Owing to the current development in radiological imaging modalities, certain anatomical or functional abnormalities could be assessed, from now on, in the psychiatric diseases that could have not been predicated upon any organic basis previously. In many studies conducted until today, diagnosis or follow-up in the course of the treatment has focused on development process of the disorder, pathophysiology, underlying progressive picture, and neural process, as well as potential factors, rather than imaging methods. Since the invention of X-rays, available information due to the advances both in radiology and in computer technology has become sharable as well. With the new methods, other than old or conventional modalities, it has been possible to not only anatomically visualize but also functionally evaluate the tissues or organs. Exposure to ionized radiation is not a matter of question with such modalities developed in MRI field. Moreover, these techniques and experiences in this field are gradually becoming available day by day. Operator and software dependent variability of these methods that has been relatively going on would be solved in time and be standardized. Current advanced MRI modalities that can be used in addition to routine examinations include high resolution imaging (3Tesla), functional magnetic resonance imaging (f-MRI), perfusion MRI (p-MRI), diffusion-weighted imaging (DWI), diffusion tensor imaging (DTI), and magnetic resonance spectroscopy (MRS). It is aimed to review the functional (f-MRI) or microanatomical structure (DWI, DTI) or metabolite (MRS) changes in imaging of the
Routing in Multi-Hop Networks

Wireless network is a collection of number of nodes. There is a single source and a single destination or number of destinations connected by the number of ways. Nodes communicate to each other by sending signals that transmits message through single source to single destination. Signals send by source are in the encoded form. When receiver receives it, process of decoding/encoding with information received from previous nodes is done. In the wireless network there is a problem of finding path which is optimal and requires less energy. In proposed system we find the optimal routing path in signal transmission from source to destination in multi-hop network. We use the rate-less code which is used to collect the data in the transmission process. This will be decrease the total energy and reduce delays in transmission. Proposed system increases significant performance of system by finding the shortest path using Floyd-Warshall algorithm. Floyd Warshall's algorithm is finds shortest path between all nodes and we have to run only once. And which is faster than those algorithms because it runs only once to find shortest path. So we are using Floyd Warshall's algorithm in multi graph system to improve performance and chances of average path loss is very low we have compared existing and proposed system based on path loss.
Determination of antioxidant and antimutagenic activities of Phlomis armeniaca and Mentha pulegium

This study was designed to determine antioxidant and antimutagenic activities of methanol and n-hexane extracts of Phlomis armeniaca and Mentha pulegium and their phenolic compounds. The extracts were screened for their possible antioxidant and antimutagenic activities by DPPH and ABTS free radical scavenging, reducing power, metal chelating and DNA nicking assays. The methanol extracts of the plants exhibited significant antioxidant activities determined by different assays. P. armeniaca showed higher activities in antioxidant assays. Also, the highest phenolic content was observed in P. armeniaca. In DNA nicking assay (antimutagenic), all extracts of these plants (20-40 µg/mL) exhibited DNA protecting activities. This study shows that methanol extracts of the plants have higher antioxidant activities than their hexane extract. Moreover, the plants can be used as natural antioxidants and antimutagenic sources.
Stream Video based Human Identification using Ai

:- face recognition becomes most widely used application from Authentication. It is used in our hand mobiles such as unlocking . it is used as another form of biometric lock, where we use iris, finger print, palm scanner. face recognition has received much attention during past few years and in future also it becomes most useful and secure one. But it can also be fooled by using spoofing attacks such as photos (shown using by smart phones, framed pictures, printouts, masks). There are many ways to achieve it but no method gives a fighting fit solution to the problem, no one gives it accurately. We propose an effective method and also robust face detection scheme with Caffe based detection scheme ,and we propose our project in ARTIFICIAL INTELLIGENT specifically in deep learning.
Biodegradation of MTBE by Bacteria Isolated From Oil Hydrocarbons- Contaminated Environments

Methyl tertiary butyl ether (MTBE) belongs to the group of gasoline oxygenates and persistent environment contaminants, and shows potential for biodegradation in aerobic and anaerobic conditions, through application of pure microbial cultures. Presented research shows that indigenous bacterial isolates 6sy and 24p, selected from oil hydrocarbons-contaminated environments, were capable of utilizing MTBE as sole carbon and energy source. Based on 16S rDNA sequence analysis, bacterial isolates 6sy and 24p were identified as Staphylococcus saprophyticus subsp. saprophyticus and Pseudomonas sp. , respectively. The MTBE biodegradation rate was affected by longevity of incubation period and initial MTBE concentration. After 3 weeks of incubation at 25°C in a dark, the removal rates of initial 25 and 125 ppm MTBE concentrations by Staphylococcus saprophyticus 6sy were found to be 97, and 63%, respectively, while efficiency of Pseudomonas sp. in degradation of indicated concentrations was 96, and 40%, respectively. Both bacterial isolates were able to grow in MTBE-containing growth medium. Highest growth rate of bacterial isolates was observed at the end of incubation period. The presented results indicated the potential of these bacterial isolates in bioremediation of MTBE-contaminated environments.
22 BEYOND BINDING : MOLECULAR AND CELL BIOLOGICAL APPROACHES TO STUDYING G-PROTEIN – COUPLED RECEPTORS

The origins of the modern concept of receptors can be traced to the beginnings of the 20th century (1). Almost two decades passed until the first neurotransmitter, acetylcholine, was identified from classic physiologic studies on the vagus nerve performed by Otto Loewi in 1921. Since these seminal discoveries the pace of advance has increased enormously. A revolution in the field began in the 1950s, with the discovery that neurotransmitter receptors are targets of clinically relevant psychotropic drugs and the development of radioligand binding techniques (2,3). Radioligand binding methodologies remain a mainstay of modern neuropsychopharmacology, and have facilitated the identification of receptor subtypes as well as the discovery of novel receptors that mediate the actions of important drugs. The application of recombinant DNA methodologies sparked a second revolution in neuropsychopharmacology. These methods facilitated the cloning of complementary DNAs (cDNAs) encoding distinct receptors, the identification of large families of homologous receptors, and unprecedented insight into subtype diversity within individual receptor families (4,5). Important families of receptors include steroid hormone receptors, receptor tyrosine kinases, ligand-gated ion channels, and G-protein–coupled receptors (GPCRs). GPCRs comprise the largest class of signal-transducing receptors, with well over 1,000 members identified in humans. In some organisms, genes encoding GPCRs comprise 1% of the genome (6). GPCRs mediate the actions of the majority of neurotransmitters and neuromodulators, as well as other important biological ligands. These receptors are also criti-

Virtual road concept as a tool for road quality research

Road quality assessment using crowdsourced data gathered by smartphone users, based on acceleration data, is an interesting subject on using modern technology for improvements of the infrastructure. The algorithms – for both road quality assessment and detection of different elements on the road – need to be tested, especially in the field. To facilitate building sets of different data and sharing them in a standardised way, the authors propose extraction of known road fragments with known types of surface degradation and construction of virtual streams of data, thus “virtual roads”. The procedure for data extraction and building a database of segments, combining them into virtual road, as well as testing real-world algorithm using the constructed virtual road are presented in the paper.
Flavonoids and the Structure-Antioxidant Activity Relationship

For thousands of years, plants have been well documented for their medicinal uses and nowadays, about 80% of world population is dependent on traditional medicines [1]. The knowledge associated with traditional medicine has promoted further investigations of medicinal plants as potential medicines and has led to the isolation of many natural products. Herbal medicine materials consist in juices, gums, essential oils and any other natural substances containing as bioactive components, underground and aerial plant parts or other plant materials, in the crude state or as plant preparations. Among all natural bioactive products, flavonoids represent a group of phenolic compounds widely distributed in the plant kingdom and they have a positive effect on human health. In plants, flavonoids are synthetized via phenylpropanoid biosynthetic pathway and their structural feature is a 2-phenyl-benzo-γ-pyrane nucleus including two aromatic rings (A and B rings) and a pyran heterocyclic ring (C ring). The A-ring originates from the cyclization of 3 molecules of malonyl CoA and it is linked to B-ring, derived from phenylalanine, by a three-carbon bridge (C-ring).
Fossorial and durophagous: implications of molluscivory for head size and bite capacity in a burrowing worm lizard

Limbless animals that burrow head-first are often considered to be evolutionarily constrained in the development of a large head, due to limitations imposed while penetrating the soil. Whilst animals with a small head experience less resistance when digging, they are believed to have a weak bite, hence restricting their potential dietary spectrum to soft prey. Yet, recent findings established molluscivory in the fossorial worm lizard Trogonophis wiegmanni (Amphisbaenia), suggesting a high bite capacity for this burrowing species necessary to crush snail shells. To tackle this burrow/crush dilemma, we examined the relationship between head morphology, bite force and gastropod diet in T. wiegmanni males and females. In vivo bite force analyses and shell hardness measurements were used to assess the potential dietary spectrum of the amphisbaenians. In addition, phylogenetic analyses were performed to put T. wiegmanni's head size and bite force into an interspecific comparative context. Our results show a strong positive relation between head size and bite force, and we found no evidence for sexual dimorphism. In sharp contrast to other durophagous lizards, T. wiegmanni combines a relatively small body and a (disproportionally) small head with relatively high biting forces. In fact, T. wiegmanni is able to crush a wide array of the most abundant gastropod shells in their environment. However, the head size of the strongest biters imposes a limitation towards a common alternative snail-feeding strategy: entering the opening of the gastropod shell. This study shows that head size, and consequently bite force, increases the number and variety of gastropods that can be consumed by ‘shell-crushing’, but reduces the number and variety of snails that can be consumed by ‘shell-entering’, and vice versa. The cranial design of (durophagous) limbless burrowers may therefore not only evolve under constraints for efficient soil penetration, but also through selection for diet.
Macroscopic morphology and arterial vascular supply of thymus in fowls (Gallus gallus domesticus) of Red Bro Cou Nu lineage

Twenty-eight fowls (Gallus gallus domesticus) of the Red Bro Cou Nu lineage were studied. They were about 35 days old and had their arteries filled with Neoprene Latex 450", aqueous solution at 50%, stained with specific pigment (Globo S/A, Tintas e Pigmentos), and then fixed in aqueous solution of formaldehyde at 10%. The present study aimed to quantify the thymic lobes and identify the main arteries responsible for the blood supply of these lobes and their frequencies. The number of thymic lobes on the right antimere varied from two to 11, with a greater frequency of 8 lobes; and the left antimere showed a variation from one to eight, with a greater frequency of five lobes. The arteries destined to the thymus were composed by direct and indirect branches of the following arteries: left and right common vagus nerve, left and right cranial thyroid, left and right caudal thyroid, left and right ascending esophageal, right ingluvial, left and right cutaneous, and right common carotid. The right thymic lobes, regardless their origin, received from eight to 27 vascular branches, and the left thymic lobes, from eight to 24 branches.
Non-singular boundary integral methods for fluid mechanics applications

Abstract A formulation of the boundary integral method for solving partial differential equations has been developed whereby the usual weakly singular integral and the Cauchy principal value integral can be removed analytically. The broad applicability of the approach is illustrated with a number of problems of practical interest to fluid and continuum mechanics including the solution of the Laplace equation for potential flow, the Helmholtz equation as well as the equations for Stokes flow and linear elasticity.
Pixel-level tunable liquid crystal lenses for auto-stereoscopic display

Mobile video and gaming are now widely used, and delivery of a glass-free 3D experience is of both research and development interest. The key drawbacks of a conventional 3D display based on a static lenticular lenslet array and parallax barriers are low resolution, limited viewing angle and reduced brightness, mainly because of the need of multiple-pixels for each object point. This study describes the concept and performance of pixel-level cylindrical liquid crystal (LC) lenses, which are designed to steer light to the left and right eye sequentially to form stereo parallax. The width of the LC lenses can be as small as 20-30 μm, so that the associated auto-stereoscopic display will have the same resolution as the 2D display panel in use. Such a thin sheet of tunable LC lens array can be applied directly on existing mobile displays, and can deliver 3D viewing experience while maintaining 2D viewing capability. Transparent electrodes were laser patterned to achieve the single pixel lens resolution, and a high birefringent LC material was used to realise a large diffraction angle for a wide field of view. Simulation was carried out to model the intensity profile at the viewing plane and optimise the lens array based on the measured LC phase profile. The measured viewing angle and intensity profile were compared with the simulation results.
BRLF 1 transcription activator IgG targeting Epstein-Barr virus hallmarks promising diagnostic efficacy in identification of nasopharyngeal carcinoma : a meta-analysis study

BRLF1 transcription activator IgG (Rta-IgG) targeting Epstein-Barr Virus (EBV) infection has been highlighted as a helpful indicator for nasopharyngeal carcinoma (NPC) diagnosis. Herein, we sought to evaluate the predictive efficacy of Rta-IgG testing for NPC identification. Electronic search was undertaken based on the platforms of online databases. STATA 12.0 and Meta-Disc 1.4 statistical programs were employed for the pooled analyses. Effects of publication bias was assessed utilizing the trim and fill adjustment method. Sixteen cohorts included 17 individual studies with 2658 NPC patients were enrolled. For the discrimination of NPC from non-NPC individuals, single testing of Rta-IgG sustained an estimated AUC (area under ROC curves) value of 0.95 (95% CI: 0.92-0.96), corresponding to a pooled sensitivity of 0.83 (95% CI: 0.78-0.87) and specificity of 0.92 (95% CI: 0.90-0.93). Deek’s funnel plot asymmetry test manifested significant publication bias. After filling the estimated missing studies, the adjusted effect of unpublished studies was slightly altered as compared to that of the unadjusted ones. Single measurement of Rta-IgG confers promising diagnostic efficacy to aid in NPC identification. More studies are still warranted to reinforce our preliminary evidence.
Quantity or Quality? Collaboration Strategies in Research and Development and Incentives to Patent

Using count data models controlling for unobserved heterogeneity, this study shows for a large sample of R&D-active manufacturing firms in Flanders that collaborative R&D has a positive effect on firms’ patenting in terms of both quantity and quality. However, when distinguishing between alliances that aim at joint creation of new knowledge and alliances that aim at the exchange of existing knowledge, the results suggest that the positive effect on patenting quantity is to a large extent driven by knowledge exchange alliances rather than joint R&D. Firms engaged in creation alliances, on the other hand, receive more forward citations per patent which indicates that joint R&D enhances patent quality. In the light of the literature on strategic patenting, our results may further suggest that creation alliances lead to patents that are filed to protect valuable intellectual property, while exchange alliances drive “portfolio patenting” which has been shown to result in fewer citations for the individual patent.
