School Correlates of Academic Behaviors and Performance Among McKinney–Vento Identified Youth

We utilized a pooled sample of elementary, middle, and high school–aged children identified as homeless via definitions set forth by McKinney–Vento legislation in a large urban district in California to estimate the extent to which school factors contributed to student attendance, suspensions, test-taking behaviors, and performance on state standardized achievement tests (N = 2,618 students in 111 schools). Results of multi-level models indicated that school factors, including school truancy and average school reading and mathematics proficiency rates, contributed to individual student outcomes. Students identified as English language learners or receiving special education services performed relatively more poorly than peers across outcomes considered.
The lipid phosphatase activity of PTEN is critical for stabilizing intercellular junctions and reverting invasiveness

To analyze the implication of PTEN in the control of tumor cell invasiveness, the canine kidney epithelial cell lines MDCKras-f and MDCKts-src, expressing activated Ras and a temperature-sensitive v-Src tyrosine kinase, respectively, were transfected with PTEN expression vectors. Likewise, the human PTEN-defective glioblastoma cell lines U87MG and U373MG, the melanoma cell line FM-45, and the prostate carcinoma cell line PC-3 were transfected. We demonstrate that ectopic expression of wild-type PTEN in MDCKts-src cells, but not expression of PTEN mutants deficient in either the lipid or both the lipid and protein phosphatase activities, reverted the morphological transformation, induced cell–cell aggregation, and suppressed the invasive phenotype in an E-cadherin–dependent manner. In contrast, overexpression of wild-type PTEN did not counteract Ras-induced invasiveness of MDCKras-f cells expressing low levels of E-cadherin. PTEN effects were not associated with marked changes in accumulation or phosphorylation levels of E-cadherin and associated catenins. Wild-type, but not mutant, PTEN also reverted the invasive phenotype of U87MG, U373MG, PC-3, and FM-45 cells. Interestingly, PTEN effects were mimicked by N-cadherin–neutralizing antibody in the glioblastoma cell lines. Our data confirm the differential activities of E- and N-cadherin on invasiveness and suggest that the lipid phosphatase activity of PTEN exerts a critical role in stabilizing junctional complexes and restraining invasiveness.
Reflection and the art of coaching: fostering high-performance in Olympic Ski Cross

In preparation for the 2010 Vancouver Winter Olympic Games, the lead author engaged in systematic reflection in an attempt to implement coaching behaviours and create practice environments that promoted athlete development (psycho-social and physical performance). The research was carried out in relation to his work as head Ski Cross coach working with (primarily) three athletes in their quest for Olympic qualification and subsequent performance success in the Olympic Games. This project sought to examine coach-athlete interactions. Of particular interest were coach and athlete responses regarding the implementation of autonomy supportive coaching behaviours in a high context. Autonomy supportive coaching behaviours have previously been strongly associated with positive athlete psycho-social and performance outcomes, however, a paucity of research has examined its implementation in high-performance contexts. Through the use of participant ethnography, it was possible to gain considerable insights regarding athletes’ perceptions of choice, implications of perceived athletic hierarchies, as well as cultural and experience-related influences on training and performance expectations.
Assessment of Borderline Personality Disorder Using the MMPI-2 and the Personality Assessment Inventory

The usefulness of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) and the. Personality Assessment Inventory (PAI) in the classification of patients diagnosed with Borderline Personality Disorder (BPD) was investigated. Twenty-two female inpatients diagnosed as having BPD and 22 female student control participants participated in the study. Those who scored 70 or above on the Borderline Features (BOR) scale of the PAI were classified as BPD. For the MMPI-2, participants with profile configurations of 8-4-2, 8-2-4, 8-4-7, or 8-2-7 were classified as BPD. Eighty-two percent of the patients and 77% of the students were classified correctly using the PAI, whereas 9% of the patients and 95% of the students were classified correctly based on the MMPI-2. The discriminant function for the selected scales of the PAI classified 8G% of the participants correctly, and the discriminant function for the selected scales of the MMPI-2 classified 84% of the participants correctly. This suggests that both tests include items that discriminate between the two groups. Overall, the classification of participants based on the BOR scale of the PAI was more accurate than the classification of participants using the profile configurations of the MMPI-2. Implications for the assessment of BPD are discussed.
Génération de plan de site web pour les non-voyants par des fourmis artificielles

The internet user can meet navigation problems in particular because of the great number of web pages and links. In order to solve this problem, we propose in this article an automatic sitemap generator. The obtained sitemap is both usable by the internet user and webmaster, but it is especially adapted to visual handicapped person or impaired memory capacities. In this paper, we present our method of sitemap generation which uses artificial ants to generate clusters of similar pages, then we use Prim algorithm on each cluster generated by ants.
Molecular determinants of fast Ca2+-dependent inactivation and gating of the Orai channels

Ca2+ influx by store-operated Ca2+ influx channels (SOCs) mediates many cellular functions regulated by Ca2+, and excessive SOC-mediated Ca2+ influx is cytotoxic and associated with disease. One form of SOC is the CRAC current that is mediated by Orai channels activated by STIM1. A fundamental property of the native CRAC and of the Orais is fast Ca2+-dependent inactivation, which limits Ca2+ influx to guard against cellular damage. The molecular mechanism of this essential regulatory mechanism is unknown. We report here the fast Ca2+-dependent inactivation is mediated by three conserved glutamates in the C termini (CT) of Orai2 and Orai3, which show prominent fast Ca2+-dependent inactivation compared with Orai1. Transfer of the CT between the Orais transfers both the extent of channel opening and the mode of fast Ca2+-dependent inactivation. Fast Ca2+-dependent inactivation of the Orais also requires a domain of STIM1; fragments of STIM1 that efficiently open Orai channels do not evoke fast inactivation unless they include an anionic sequence that is C-terminal to the STIM1-Orai activating region (SOAR). Our studies suggest that Orai CT are necessary and sufficient to control pore opening and uncover the molecular mechanism of fast Ca2+-dependent inactivation that has implications for Ca2+ influx by SOC in physiological and pathological states.
Origin and subset distribution of peripheral blood dendritic cells in patients with chronic graft-versus-host disease1

Background. After allogeneic hematopoietic stem cell transplantation, donor T cells interact with an antigen-presenting cell environment that is distorted in number, level of activation, and origin. The role of antigen presentation in the development of chronic graft-versus host disease (cGVHD) is unknown. Methods. The number and origin of peripheral blood immature myeloid (CD19− CD1c+) and plasmacytoid (BDCA-2+) dendritic cells (DCs) was determined in 30 patients at more than 100 days after allogeneic hematopoietic stem cell transplantation. Results. Patients with cGVHD had significantly higher plasmacytoid DC numbers than individuals without this complication (9.1±2.0×106/L versus 3.8±0.6×106/L, P =0.025). Chimerism studies demonstrated that DCs in patients with cGVHD were exclusively of donor origin, whereas persistence of host DCs was observed in some control patients. Conclusions. The antigen-presenting cell environment in patients with cGVHD, as represented by immature blood DCs, is of donor origin but distorted in terms of subset distribution.
5G Position and Orientation Estimation through Millimeter Wave MIMO

Millimeter wave and massive MIMO are considered enabling technologies for future 5G networks. While their benefits for achieving high-data rate communications are well- known, their potential advantages for accurate positioning are largely undiscovered. We derive sufficient conditions under which transmission from a single mm-wave base station leads to a non- singular Fisher information matrix associated with the position and orientation of a user terminal equipped with multiple antennas, which is in turn a prerequisite for joint estimation of the position and orientation.
Effects of montelukast sodium on tendon healing: An experimental study

Introduction: Montelukast sodium (MS) a selective leukotriene antagonist of the cysteinyl leukotriene receptor, has been used in the treatment of asthma and allergic rhinitis. In this study, we evaluated the effect of MS on the early inflammatory phase (histological) of nonsynovial tendon healing. Materials and Methods: Rats were divided randomly into two groups (n = 6 each). MS (Singulair) was administered to one group at 10 mg/kg/day [250 g/day intraperitoneally (i.p.)]. The control group was administered 250 g/day of 0.9% saline i.p. This nonsynovial tendon was longitudinally divided at the midportion, cut transversely and then sutured. In both groups, the rats were sacrificed by decapitation 10 days later. Results: Decreased inflammatory cell infiltration and more properly oriented collagen fibres were observed in the MS group's histopathological specimens as compared to the control group's (P < 0.05). Additionally, vascularity was decreased in the MS group. Conclusion: MS decreased tendon healing, apparently by inhibiting the early inflammatory phase of nonsynovial tendon healing.
Short-Term Preoperative Calorie and Protein Restriction Is Feasible in Healthy Kidney Donors and Morbidly Obese Patients Scheduled for Surgery

Introduction. Surgery-induced oxidative stress increases the risk of perioperative complications and delay in postoperative recovery. In mice, short-term preoperative dietary and protein restriction protect against oxidative stress. We investigated the feasibility of a calorie- and protein-restricted diet in two patient populations. Methods. In this pilot study, 30 live kidney donors and 38 morbidly obese patients awaiting surgery were randomized into three groups: a restricted diet group, who received a synthetic liquid diet with 30% fewer calories and 80% less protein for five consecutive days; a group who received a synthetic diet containing the daily energy requirements (DER); and a control group. Feasibility was assessed using self-reported discomfort, body weight changes, and metabolic parameters in blood samples. Results. Twenty patients (71%) complied with the restricted and 13 (65%) with the DER-diet. In total, 68% of the patients reported minor discomfort that resolved after normal eating resumed. The mean weight loss on the restricted diet was significantly greater (2.4 kg) than in the control group (0 kg, p = 0.002), but not in the DER-diet (1.5 kg). The restricted diet significantly reduced levels of serum urea and plasma prealbumin (PAB) and retinol binding protein (RBP). Conclusions. A short-term preoperative calorie- and protein-restricted diet is feasible in kidney donors and morbidly obese patients. Compliance is high and can be objectively measured via changes in urea, PAB, and RBP levels. These results demonstrate that this diet can be used to study the effects of dietary restriction on surgery-induced oxidative stress in a clinical setting.
Augmentation of natural killer cell activity in vivo against tumour cells by some wild plants from Jordan

Twelve aqueous extracts prepared from Jordanian plants that are currently used in traditional medicine to treat various types of cancer were tested in mice for their augmentation of natural killer cells in vivo in generating cytotoxicity against YAC tumour targets. After 1 week of oral administration of aqueous extracts of fresh Nigella sativum (N.s.) seeds and Allium sativum (A.s.) bulbs significant augmentation of splenic natural killer (NK) cells (62.3% ± 6.4% and 52.6% ±5.4% cytotoxicity, respectively), was obtained in comparison with spontaneous activity (24.5% ± 1.6%) at 200:1 effector:target ratio. Onopordum acanthium (O.a.) stem and leaves and Allium cepa (A.c.) bulbs showed intermediate augmentation (38.6% ± 3.8% and 30.6% ± 3.4% cytotoxicity, respectively) while the rest showed insignificant augmentation activity. The fresh aqueous extract of a mixture of the plants with high and intermediate activity showed little insignificant augmentation activity (72.7% ± 6.7% cytotoxicity) of NK cells compared with that obtained with each plant alone.

Abstract Data Machine: Data Classifier for Reliable Embedded Systems Software

In this paper, we present our ongoing work and formalism of a novel data classification method (Abstract Data Machine) for reliable software systems. Most of the approaches for data classification are based on statistical classification, e.g. machine-learning algorithms that comes with false rates. Another critical problem with such algorithms is that they are not reliable and thus do not ensure any provable assurances. One approach to establish reliability of the algorithms is to classify arbitrary data with an appropriate (pragmatically useful) level of abstraction based on the logical data properties that are amenable to assurances, i.e. a formal proof that data represented by a class indeed respects properties of the class. Furthermore, the formal proofs are fundamental for the security assurance of the applications using the algorithms in general and data security in particular.
Fast convolutions meet Montgomery

Arithmetic in large ring and field extensions is an important problem of symbolic computation, and it consists essentially of the combination of one multiplication and one division in the underlying ring. Methods are known for replacing one division by two short multiplications in the underlying ring, which can be performed essentially by using convolutions. However, while using school-book multiplication, modular multiplication may be grouped into 2M(R) operations (where M(R) denotes the number of operations of one multiplication in the underlying ring), the short multiplication problem is an important obstruction to convolution. It raises the costs in that case to 3M(R). In this paper we give a method for understanding and bypassing this problem, thus reducing the costs of ring arithmetic to roughly 2M(R) when also using fast convolutions. The algorithms have been implemented with results which fit well the theoretical prediction and which shall be presented in a separate paper.
GABA transporter function, oligomerization state, and anchoring: correlates with subcellularly resolved FRET

The mouse γ-aminobutyric acid (GABA) transporter mGAT1 was expressed in neuroblastoma 2a cells. 19 mGAT1 designs incorporating fluorescent proteins were functionally characterized by [3H]GABA uptake in assays that responded to several experimental variables, including the mutations and pharmacological manipulation of the cytoskeleton. Oligomerization and subsequent trafficking of mGAT1 were studied in several subcellular regions of live cells using localized fluorescence, acceptor photobleach Förster resonance energy transfer (FRET), and pixel-by-pixel analysis of normalized FRET (NFRET) images. Nine constructs were functionally indistinguishable from wild-type mGAT1 and provided information about normal mGAT1 assembly and trafficking. The remainder had compromised [3H]GABA uptake due to observable oligomerization and/or trafficking deficits; the data help to determine regions of mGAT1 sequence involved in these processes. Acceptor photobleach FRET detected mGAT1 oligomerization, but richer information was obtained from analyzing the distribution of all-pixel NFRET amplitudes. We also analyzed such distributions restricted to cellular subregions. Distributions were fit to either two or three Gaussian components. Two of the components, present for all mGAT1 constructs that oligomerized, may represent dimers and high-order oligomers (probably tetramers), respectively. Only wild-type functioning constructs displayed three components; the additional component apparently had the highest mean NFRET amplitude. Near the cell periphery, wild-type functioning constructs displayed the highest NFRET. In this subregion, the highest NFRET component represented ∼30% of all pixels, similar to the percentage of mGAT1 from the acutely recycling pool resident in the plasma membrane in the basal state. Blocking the mGAT1 C terminus postsynaptic density 95/discs large/zona occludens 1 (PDZ)-interacting domain abolished the highest amplitude component from the NFRET distributions. Disrupting the actin cytoskeleton in cells expressing wild-type functioning transporters moved the highest amplitude component from the cell periphery to perinuclear regions. Thus, pixel-by-pixel NFRET analysis resolved three distinct forms of GAT1: dimers, high-order oligomers, and transporters associated via PDZ-mediated interactions with the actin cytoskeleton and/or with the exocyst.
A Demo on Using Visualization to Aid Run-Time Verification of Dynamic Service Systems

Future software systems will be dynamic service oriented systems. Service-Oriented Architecture (SOA) provides an extensible and dynamic architecture to be used, for example, in smart environments. In such an environment, software has to adapt its behaviour dynamically. Thus, there is a need for Verifying and Validating (V & V) the adaptations at run-time. This paper contributes to that by introducing a novel visualization tool to be used with traditional V & V techniques to aid the software analysts in the verification process of dynamic software systems. When Quality of Service (QoS) of dynamic software systems varies due to the changing environment the Interactive Quality Visualization (IQVis) tool detects these changes and provides analysts an easier way of understanding the changed behaviour of the system.
Paper-based, inkjet-printed, text-meandered UHF resonant antennas for RFID applications

In this paper different antenna's manufacturing and designing techniques are combined with the aim of building useful radiators resonating in the UHF band. The meander lines techniques is exploited in this work with the exception of letters as meander elements. The technologically advanced and already well established silver inkjet printing technique is used for antenna realization. An unusual paper-based substrate is chosen, according with the concepts to lower costs, simplify fabrication procedures and advance usability, towards the realization of antenna for RFID applications. All design phases are discussed and a complete test of the proposed antennas is performed.
VOLATILE FATTY ACIDS AS ELECTRON DONORS FOR THE REDUCTIVE DECHLORINATION OF CHLOROETHENES

ABSTRACT Uses of a mixture of six volatile fatty acids (VFAs) including acetic, propionic, butyric, isobutyric, valeric and isovaleric acids as electron donors for the reductive dechlorination of chloroethenes have been investigated by both microcosm and column studies. The fates of tetrachloroethene (PCE), cis-dichloroethene (cis-DCE) and vinyl chloride (VC) in the presence of VFAs and in the absence of VFAs were respectively documented. The results showed that VFAs stimulated complete reductive dechlorination of chloroethenes, either as direct substrates for the dechlorinating bacteria or via H2 formed during VFAs-degradation. There were sequential utilizations of different VFAs by fermenting bacteria. In the microcosm, propionic acid was the first to be used, followed by acetic, butyric, isobutyric, valeric, and isovaleric acids, and their mean first-order degradation rates obtained were 0.128, 0.048, 0.016, 0.027, 0.025 and 0.003 day−1, respectively. In the column, propionic acid was the first to be used, followed by butyric and valeric acids, and their calculated first-order degradation rates were 0.833, 0.403 and 0.260 day−1, respectively.
Chapter 55: Video-as-data and Digital Video Manipulation Techniques for Transforming Learning Sciences Research, Education, and Other Cultural Practices

This chapter concerns the theoretical and empirical foundations and current progress of the Digital Interactive Video Exploration and Reflection (DIVER) Project at Stanford University. The DIVER Project aspires to accelerate cultural appropriation of video as a fluid expressive medium for generating, sharing, and critiquing different perspectives on the same richly recorded events and to work with others to establish a Digital Video Collaboratory (DVC) that enables cumulative knowledge building from video-as-data for discovery and commentary. These uses of digital video manipulation are very distinctive from those used in virtual-learning environments today across K-12, higher education, and corporate training (e.g., BlackBoard, WebCT, PlaceWare), which are primarily video clips that are used to illustrate a point or concept during a lecture or a video of a faculty member teaching and using PowerPoint slides. The DIVER system distinctively enables “point of view” authoring of video tours of archival materials (from video to animations and static imagery) in a manner that supports sharing, collaboration, and knowledge building around
Emotion Recognition System for English Dialects using Dimensional Theory

In this paper Emotion recognition often refers to the science and technology of developing algorithms and implementing them on machines to recognize the Emotions. Research in the field of Emotion recognition has made a number of significant advances in the last two decades. emotion recognition results from speech signals, with particular focus on extracting emotion features from the short utterances typical of Interactive Voice Response (IVR) applications. This paper proposes a new approach to emotion recognition, making use of two of the emotional dimensions, arousal and valence and their relationship with different kind of features. The classification of various types of emotions such as sadness, boredom, happy, and cold anger. Emotion has used a dimensional theory proposed a dimensional model of emotion that is founded on a biological organization of appetitive and defensive motivational connections in the human cognitive system. We use a database from the Linguistic Data Consortium at University of Pennsylvania, which is recorded by 8 actors expressing 15 emotions. Results indicate that hot anger and neutral utterances can be distinguished with over 90% accuracy. We show results from recognizing other emotions. We also illustrate which emotions can be clustered together using the selected prosodic features.
