Social Support and Service Use Among Homeless Persons With Serious Mental Illness

It has been widely hypothesized that persons with greater social support use fewer health care services, although previous studies have shown variable results. This study examines the relationship between levels of social support and formal service use among clients entering 18 community treatment programs for homeless persons with serious mental illness as part of the ACCESS demonstration project of the U.S. Center for Mental Health Services. Baseline and follow-up data on 1,828 clients entering the ACCESS program were used to evaluate the relationship between individual client socio-demographic and clinical characteristics, seven measures of social support, and levels of formal service use in this population. Three measures of social support were positively related to the use of outpatient medical services and one each to the use of substance abuse services and the total days of service use. Six out of seven measures of social support were positively related to the receipt of multiple services. It appears that social support is most strongly associated with improved access to an array of different services - a very important need among this population.
THE VEDIC IMPERATIVES yodhi 'FIGHT' AND bodhi 'HEED'

The 2nd sg. imperatives yodhi (: yudh- 'fight') and bodhi (: budh- 'awake, heed') are usually seen as athematic imperatives in -dhi with irregular guna of the root syllable and reduction of the geminate cluster -ddhi- to -dh-. It is argued here, by contrast, that these forms are actually analogical creations on the basis of the 2nd sg. imperative josi ( jus- 'enjoy'). Etymologically and historically, josi is a si- imperative (*jos-si), haplologized from a 2nd sg. subjunctive *josasi/*geusesi. Synchronically, however, it appeared to be an i-imperative based on the gunated root, and the overall parallelism of the verbs yudh-, budh-, and jus- led to the creation of yodhi and bodhi on the same model.
Towards Quality Checkers for Web Site Designs

Building high-quality web sites is a challenging task, but many sites are necessarily created by non-professional designers. We are working towards creating design tools that incorporate a quality-checker, in analogy to grammarcheckers found in word processors, to help such designers. Towards this end, we have developed a system that computes a set of quantitative measures that can characterize the informational, navigational, and graphical aspects of the web site, and have shown that even a small set of such measures can be used to successfully distinguish highly-rated web sites from poorly-rated ones. We have also developed statistical pro les from these empirically-derivedmeasures and incorporated these proles into a rudimentary tool that provides some support for improving an implemented site. The next step is to develop an interactive web site evaluation tool that can help non-professional designers understand where and how their current design (an implemented site or early prototype) can be improved, based on its di erences from sites designed for similar purposes.
Determination of Perfluorinated Compounds in Packaging Materials and Textiles Using Pressurized Liquid Extraction with Gas Chromatography-Mass Spectrometry

A simultaneous determination method of trace amounts of perfluorinated compounds, such as perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) in packaging materials and textiles, has been developed, using pressurized liquid extraction (PLE) with gas chromatography–mass spectrometry (GC/MS). The perfluorinated compounds were primarily extracted from the samples by a PLE procedure, in which the parameters were optimized by response surface methodology. The solvent was then removed by blowing nitrogen and a silylation step was carried out with N , N -bis(trimethylsilyl)trifluoroacetamide. The silylated compounds were identified and quantified by GC/MS. The proposed method was applied to determine the PFOA and PFOS in polytetrafluoroethylene packaging materials and textiles, where the detection limits of the two compounds were 1.6 and 13.9 ng mL^−1, respectively. The results showed that the concentrations of PFOA and PFOS in the packaging materials and textiles ranged from 17.5 to 45.9 and 33.7 to 81.3 ng g^−1, respectively.
Shock profiles for the Shallow-water Exner models

This article is devoted to analyze some ambiguities coming from a class of sediment transport models. The models under consideration are governed by the coupling between the shallow-water and the Exner equations. Since the PDE system turns out to be an hyperbolic system in non conservative form, ambiguities may occur as soon as the solution contains shock waves. To enforce a unique definition of the discontinuous solutions, we adopt the path-theory introduced by Dal Maso, LeFLoch and Murat. According to the path choices, we exhibit several shock definitions and we prove that a shock with a constant propagation speed and a given left state may connect an arbitrary right state. As a consequence, additional assumptions (coming from physical considerations or other arguments) must be chosen to enforce a unique definition. Moreover, we show that numerical ambiguities may still exist even when such a choice is made.
Colesterol: modificações da metodologia oficial do Instituto Adolfo Lutz e sua quantificação em massas alimentícias

O teor de colesterol é utilizado pela legislação vigente como parâmetro no controle do número de ovos utilizados na fabricação de massas alimentícias. A modificação proposta no procedimento analítico utilizado no Instituto Adolfo Lutz, apresentou vantagens conduzindo a obtenção de resultados mais reprodutíveis e com maior exatidão. Essas modificações foram com relação à extração do colesterol, bem como na formação do complexo colorido responsável pela absorção medida espectrofotométricamente. A metodologia proposta foi aplicada em amostras de ovos "in natura", gemas liofilizadas e massas alimentícias com ovos, o que permitiu verificar que 44,44% das massas analisadas apresentaram teor de colesterol abaixo do limite mínimo exigido pela legislação em vigor.
Sentence Correction using Recurrent Neural Networks Gene

In this work, we propose that a pre-processing method for changing text data to conform closer to the distribution of standard English will help increase the performance of many state-of-the-art NLP models and algorithms when confronted with data taken “from the wild”. Our system receives as input a text word, sentence or paragraph which we assume contains (possibly none) random corruptions; formally, we say that the input comes from a corrupted language domain that is a superset of our target language domain. Our system then processes this input and outputs a “translation” or “projection” to our target language domain, with the goal of the output being to preserve the latent properties of the input text (sentiment, named entities, etc.) but mutated in a way that embeds these properties in a representation familiar to other NLP systems.
Acute kidney injury in congenital heart disease

Purpose of review Acute kidney injury (AKI) is associated with significant morbidity and mortality in patients with congenital heart disease undergoing cardiac surgery or in pediatric patients with congestive heart failure. Recent findings This review describes the definition and various manifestations of AKI, the impact of biomarkers on the diagnosis of AKI, the importance of fluid overload as a consequence of AKI and its long-term impact. Summary There are novel biomarkers for AKI detection that should facilitate early recognition and intervention to prevent or attenuate the effects of AKI and fluid overload. Previous conventional wisdom that survivors of AKI fully recover renal function without subsequent consequences is flawed.
Mining Frequent Independent Patterns and Frequent Correlated Patterns Synchronously

One of the main tasks of KDTCM (knowledge discovery in Traditional Chinese Medicine) is discovering novel paired or grouped drugs in Chinese Medical Formula (CMF) database, which are special combinations of two or more drugs. Correlation mining is much effective because of the large number of correlation relationships among various kinds of drugs. However, an independent pattern might have much more probability than a correlated pattern to be a novel paired or grouped drug even if they have same support for the sake of the downward closure property of independence. Therefore, we mine frequent independent patterns and frequent correlated patterns synchronously. Notions of an independent pattern and a correlated pattern are given. An algorithm is developed for mining frequent independent patterns and frequent correlated patterns synchronously. Experimental results show the effectiveness and the correctness of the techniques developed in this paper. Experimental results also show the great necessity of mining independent patterns and correlated patterns synchronously.
Domain assignment for protein structures using a consensus approach: Characterization and analysis

A consensus approach for the assignment of structural domains in proteins is presented. The approach combines a number of previously published algorithms, and takes advantage of the elevated accuracy obtained when assignments from the individual algorithms are in agreement. The consensus approach is tested on a data set of 55 protein chains, for which domain assignments from four automated methods were known, and for which crystallographers assignments had been reported in the literature. Accuracy was found to increase in this test from 72% using individual algorithms to 100% when all four methods were in agreement. However a consensus prediction using all four methods was only possible for 52% of the dataset. The consensus approach (using three publicly available domain assignment algorithms (PUU, DETECTIVE, DOMAK)) was then used to make domain assignments for a data set of 787 protein chains from the Protein Data Bank. Analysis of the assignments showed 55.7% of assignments could be made automatically and of these, 13.5% were multi‐domain proteins. Of the remaining 44.3% that could not be assigned by the consensus procedure 90.4% had their domain boundaries assigned correctly by at least one of the algorithms. Once identified, these domains were analyzed for trends in their size and secondary structure class. In addition, the discontinuity of each domain along the protein chain was considered.
Using multiple views for gait-based gender classification

Automatic gender classification of an individual can be very useful in video-based surveillance systems and human-computer interaction systems. In this paper, we propose an approach to integrate information from multi-view gait at the feature level. First, gait energy images (GEI) are constructed from the video streams for different viewpoints. Then, the feature fusion is performed by putting GEI images and camera views together to generate a third-order tensor (x, y, view). A multilinear principal component analysis is employed to reduce dimensionality of the tensor objects which integrate all views. Compared with other methods, the proposed fusion scheme shows more effective performance for multi-view gait based gender classification.
MiR-21 is Enriched in the RNA-Induced Silencing Complex and Targets COL4A1 in Human Granulosa Cell Lines

MicroRNAs (miRNAs) are noncoding small RNAs that play important roles in a variety of physiological and pathological events. In this study, we performed large-scale profiling of EIF2C2-bound miRNAs in 3 human granulosa-derived cell lines (ie, KGN, HSOGT, and GC1a) by high-throughput sequencing and found that miR-21 accounted for more than 80% of EIF2C2-bound miRNAs, suggesting that it was enriched in the RNA-induced silencing complex (RISC) and played a functional role in human granulosa cell (GC) lines. We also found high expression levels of miR-21 in primary human GCs. Assuming that miR-21 target mRNAs are enriched in RISC, we performed cDNA cloning of EIF2C2-bound mRNAs in KGN cells. We identified COL4A1 mRNA as a miR-21 target in the GC lines. These data suggest that miR-21 is involved in the regulation of the synthesis of COL4A1, a component of the basement membrane surrounding the GC layer and granulosa-embedded extracellular structure.
No association between allelic variants of HOXA1/HOXB1 and autism

Two recent studies have reported conflicting findings of association of a variant in the HOXA1 gene and autism. To try to resolve the conflict in findings, we conducted an association study in 78 Irish families of the reported DNA variants. We did not find statistically significant association between the variants and autism. Similarly there was no evidence of preferential transmission of variants from parent of either sex to affected offspring. We also report negative findings for HOXB1 variants. We conclude that the HOXA1/B1 are unlikely to be the susceptibility genes for autism in our sample. © 2003 Wiley‐Liss, Inc.
An Inverse Finite Element Approach for Identifying Forces in Biological Tissues

For centuries physicians, scientists, engineers, mathematicians, and many others have been asking: ‘what are the forces that drive tissues in an embryo to their final geometric forms? ’ At the tissue and whole embryo level, a multitude of very different morphogenetic processes, such as gastrulation and neurulation are involved. However, at the cellular level, virtually all of these processes are evidently driven by a relatively small number of internal structures all of whose forces can be resolved into equivalent interfacial tensions γ. Measuring the cell-level forces that drive specific morphogenetic events remains one of the great unsolved problems of biomechanics. Here I present a novel approach that allows these forces to be estimated from time lapse images. In this approach, the motions of all visible triple junctions formed between trios of cells adjacent to each other in epithelia (2D cell sheets) are tracked in time-lapse images. An existing cell-based Finite Element (FE) model is then used to calculate the viscous forces needed to deform each cell in the observed way. A recursive least squares technique with variable forgetting factors is then used to estimate the interfacial tensions γ that would have to be present along each cell-cell interface to provide those forces, along with the attendant pressures in each cell. The algorithm is tested extensively using synthetic data from an FE model. Emphasis is placed on features likely to be encountered in data from live tissues during morphogenesis and wound healing. Those features include algorithm stability and tracking despite input noise, interfacial tensions that could change slowly or suddenly, and complications from imaging small regions of a larger epithelial tissue (the frayed boundary problem). Although the basic algorithm is highly sensitive to input noise due to the ill-conditioned nature of the system of equations that must be solved to obtain the interfacial tensions, methods are introduced to improve the resulting force and pressure estimates. The final algorithm returns very good estimates for interfacial tensions and intracellular cellular pressures when used with synthetic data, and it holds great promise for calculating the forces that remodel live tissue.
High Lymph Vessel Density and Expression of Lymphatic Growth Factors in Peritoneal Endometriosis

To investigate the occurrence of lymph vessels and lymphangiogenic growth factors in peritoneal lesions, we performed immunohistochemical staining of peritoneal lesions of 37 patients with antibodies against podoplanin (D2-40), lymphatic vessel endothelial hyaluronan receptor 1 (LYVE-1), prospero homeobox protein 1 (Prox-1), vascular epithelial growth factor (VEGF)-C/VEGF-D. Overall, 10 lesions were double stained against D2-40 and von Willebrand factor. The lymph vessel density in peritoneal lesion was significantly higher in comparison with healthy peritoneum. All lymph vessel makers could be detected, whereby the lymph vessel density of LYVE-1- and Prox-1-positive lymph vessels was significantly higher than the lymph vessel density of D2-40-positive lymph vessels. Endometriotic epithelial cells and stromal cells (SCs) showed a moderate-to-strong VEGF-C/VEGF-D expression. The VEGF-C-/VEGF-D-positive macrophages in endometriotic SCs could be observed. The lymphatic vasculature seems to form a further component of peritoneal lesions and could be involved in the inflammatory process. These data demonstrated a further step in the clarification of the pathogenesis of endometriosis.
Colony-stimulating factor 1 expression is down-regulated during the adipocyte differentiation of H-1/A marrow stromal cells and induced by cachectin/tumor necrosis factor

We isolated clonal sublines of the established mouse marrow stromal cell line, H-1. These clonal sublines underwent differentiation into adipocytes in various degrees. One subline, H-1/A, underwent adipocyte differentiation after confluence, while another subline, H-1/D, did not differentiate. In H-1/A cells, the 4.5- and 2.5-kb major mRNA species of colony-stimulating factor 1 (CSF-1) were expressed before differentiation and were down-regulated at a posttranscriptional level during the differentiation of H-1/A cells. The down-regulation of the CSF-1 gene was not a result of arrested cellular growth, because no down-regulation was detected in the nondifferentiating sister line, H-1/D. This down-regulation appeared to be an early event in differentiation. Cachectin/tumor necrosis factor transiently induced the expression of CSF-1 and inhibited the differentiation of H-1/A cells into adipocytes. This induced expression of CSF-1 was due to an increased rate of transcription.
Fast permutation routing in a class of interconnection networks

This paper considers the following permutation routing problem: Given an N × N augmented data manipulator (ADM) network and a permutation π between its N inputs and outputs, can all the traffic connections of π be routed through the network in one pass? A number of backtrack search algorithms have been devised for recognizing ADM admissible permutations. None of the published results, however, appears to settle the time complexity of the problem. The goal of this paper was to answer the question positively by showing the first polynomial time bound for solving the problem. The devised algorithm requires O(N1.695) time to decide whether a given permutation π is admissible and compute a setting of the switches whenever π is admissible. For many practical applications, the obtained bound compares favorably with the O(N lg N) size of an N‐input ADM network. © 2002 Wiley Periodicals, Inc.
Neuroprotector effect of p,p'‐methoxyl‐diphenyl diselenide in a model of sporadic dementia of Alzheimer's type in mice: contribution of antioxidant mechanism

The present study investigated whether the antioxidant activity of p,p'‐methoxyl‐diphenyl diselenide [(MeOPhSe)2] is involved in its protective effect against cognitive impairment induced by streptozotocin (STZ) in a model of sporadic dementia of Alzheimer's type (SDAT). Swiss mice were treated with STZ or vehicle [2 µl of 2·5 mg ml−1 solution; intracerebroventricularly (i.c.v.)] twice, 48 h apart. (MeOPhSe)2 (25 mg kg−1) or vehicle was orally administered 30 min prior to each STZ treatment. Neuroprotector effect of (MeOPhSe)2 on the behavioral performance of mice on spatial recognition memory consolidation was investigated in the Y‐maze test. After that, mouse brains were removed for measuring antioxidant parameters. (MeOPhSe)2 protected against the impairment in learning and memory caused by i.c. v. administration of STZ in mice. (MeOPhSe)2 protected against the increase in reactive species and the reduction of glutathione levels, as well as, the increase in superoxide dismutase and glutathione S‐transferase activities caused by STZ in whole brain. These results suggest that antioxidant property is involved, at least in part, in the neuroprotective effect of (MeOPhSe)2 on SDAT induced by STZ in mice. Copyright © 2011 John Wiley & Sons, Ltd.
Cardiovascular risk-associated allele frequencies for 15 genes in healthy elderly French and Chinese

Abstract In order to investigate possible ethnic differences in genetic and environmental determinants, we investigated several cardiovascular disease-associated genetic variations in successful ageing populations of France (Nancy) and China (Hong Kong). Allelic frequencies of these genetic variations were compared between healthy elderly Chinese (n=103) and French populations (n=100). A multi-locus assay was used to genotype 15 genes for 29 biallelic sites, genes implicated in lipid and homocysteine metabolism, thrombosis, leukocyte adhesion, and blood pressure regulation. For most of the candidate markers within lipid metabolism genes, the less frequent alleles were more common in the Chinese population compared with the French population, while the less frequent alleles of the majority of the other markers were detected only or more commonly in the French population. In conclusion, polymorphisms in 13 genes exhibited statistically significant differences in allelic frequencies between the two populations. Since the two populations were selected as examples of successful ageing, we could hypothesise that genetic factors that could play a role in a successful ageing process may be different between the two populations.
Linear prediction: A tutorial review

This paper gives an exposition of linear prediction in the analysis of discrete signals. The signal is modeled as a linear combination of its past values and present and past values of a hypothetical input to a system whose output is the given signal. In the frequency domain, this is equivalent to modeling the signal spectrum by a pole-zero spectrum. The major part of the paper is devoted to all-pole models. The model parameters are obtained by a least squares analysis in the time domain. Two methods result, depending on whether the signal is assumed to be stationary or nonstationary. The same results are then derived in the frequency domain. The resulting spectral matching formulation allows for the modeling of selected portions of a spectrum, for arbitrary spectral shaping in the frequency domain, and for the modeling of continuous as well as discrete spectra. This also leads to a discussion of the advantages and disadvantages of the least squares error criterion. A spectral interpretation is given to the normalized minimum prediction error. Applications of the normalized error are given, including the determination of an "optimal" number of poles. The use of linear prediction in data compression is reviewed. For purposes of transmission, particular attention is given to the quantization and encoding of the reflection (or partial correlation) coefficients. Finally, a brief introduction to pole-zero modeling is given.
Light Trapping in Finite Arrays of Metallic U-Shaped Cavities for Sensing With High Figures of Merit

We report conditions for light trapping in subwavelength metallic U-shaped cavities. Full and partial light trapping exhibiting optical power flow vortices originate in coupling of surface plasmons into cavity modes. Localized surface plasmons coupled into cavity modes realize full light trapping, whereas propagating surface plasmons coupled into cavity modes result in partial light trapping. For full light trapping, an intense power flow is entirely confined in the cavities, reaching its maximum values on the cavities' surfaces. The full light trapping resonance realizes high sensitivity and figure of merit in structures as short as five adjacent cavities.
