Peer Influences on the Dating Aggression Process Among Brazilian Street Youth

This study explored risk factors for adolescent dating aggression (ADA) among Brazilian street youth. Forty-three adolescents, between the ages of 13 and 17 years, were recruited at services centers in Porto Alegre, Brazil. Simultaneous multiple regression revealed that ADA was significantly predicted by adolescent dating victimization (ADV), and that this relationship was moderated by peer involvement in dating aggression. Results also revealed that peer involvement in dating aggression did not significantly predict ADA. These findings suggested that having peers who are involved in dating aggression exacerbates the effects of dating victimization on ADA among Brazilian street youth. However, ADV might be a stronger risk factor for dating aggression in this population, because when controlling for the effects of victimization in dating conflicts peer abuse toward romantic partners did not uniquely contribute to ADA.
CONFORMAL COCHAINS

In this paper we define holomorphic cochains and an associated period matrix for triangulated closed topological surfaces. We use the combinatorial Hodge star operator introduced in [18], which depends on the choice of an inner product on the simplicial 1-cochains. We prove that for a triangulated Riemannian 2-manifold (or a Riemann surface), and a particularly nice choice of inner product, the combinatorial period matrix converges to the (conformal) Riemann period matrix as the mesh of the triangulation tends to zero.
Lung Cancer–Associated Myofibroblasts Reveal Distinctive Ultrastructure and Function

Background: Cancer-associated stromal cells interact with carcinoma cells and thus participate in tumor growth. Our aim was to characterize the ultrastructure and contractile properties of stromal cells in collagen gel cultured from lung cancer of various histological types and from tumor-free lung. Methods: Cells cultured from lung cancer (13 adenocarcinomas, six squamous cell carcinomas, one adenosquamous carcinoma, and one pleomorphic carcinoma) and tumor-free lung were analyzed by transmission electron microscopy and three-dimensional collagen gel contraction assays. The expression of &agr;-smooth muscle actin (&agr;-SMA), a recognized myofibroblast marker, was examined by immunoelectron microscopy from individual cells and by Western blotting from the whole cultured cell population. Results: According to their ultrastructure, the cell lines were composed of fibroblastic and myofibroblastic cells. In electron microscopy, cells of lung cancer exhibited more myofibroblastic features displaying higher amounts of actin belts (p = 0.057) and &agr;-SMA labeling (p = 0.010) than cells from tumor-free lung. Myofibroblasts cultured from lung cancer of smokers expressed less &agr;-SMA labeling (p = 0.013) than counterparts from nonsmokers. Western blotting revealed that cancer-associated fibroblasts expressed more &agr;-SMA (p = 0.006) than cells from tumor-free lung, whereas cells from tumor-free central lung of smokers showed less &agr;-SMA (p = 0.039) than counterparts from nonsmokers. Cells cultured from cancer contracted more in collagen gel than those from tumor-free lung. The contractile capacity in collagen gel correlated with the frequency of extracellular component of fibronexus by transmission electron microscopy. Conclusions: Lung cancer–associated myofibroblasts are different both ultrastructurally and functionally when compared with cells cultured from tumor-free lung. Smoking altered myofibroblastic phenotype, regardless of their origin.
Two ATP Binding Cassette G Transporters, Rice ATP Binding Cassette G26 and ATP Binding Cassette G15, Collaboratively Regulate Rice Male Reproduction1[OPEN]

Two ATP binding cassette G transporters play a collaborative role in transferring lipidic molecules from tapetal cells for the development of anther cuticle and pollen exine. Male reproduction in higher plants requires the support of various metabolites, including lipid molecules produced in the innermost anther wall layer (the tapetum), but how the molecules are allocated among different anther tissues remains largely unknown. Previously, rice (Oryza sativa) ATP binding cassette G15 (ABCG15) and its Arabidopsis (Arabidopsis thaliana) ortholog were shown to be required for pollen exine formation. Here, we report the significant role of OsABCG26 in regulating the development of anther cuticle and pollen exine together with OsABCG15 in rice. Cytological and chemical analyses indicate that osabcg26 shows reduced transport of lipidic molecules from tapetal cells for anther cuticle development. Supportively, the localization of OsABCG26 is on the plasma membrane of the anther wall layers. By contrast, OsABCG15 is polarly localized in tapetal plasma membrane facing anther locules. osabcg26 osabcg15 double mutant displays an almost complete absence of anther cuticle and pollen exine, similar to that of osabcg15 single mutant. Taken together, we propose that OsABCG26 and OsABCG15 collaboratively regulate rice male reproduction: OsABCG26 is mainly responsible for the transport of lipidic molecules from tapetal cells to anther wall layers, whereas OsABCG15 mainly is responsible for the export of lipidic molecules from the tapetal cells to anther locules for pollen exine development.

Dimensionality Reduction using Genetic Algorithm for Improving Accuracy in Medical Diagnosis

The technological growth generates the massive data in all the fields. Classifying these highdimensional data is a challenging task among the researchers. The high-dimensionality is reduced by a technique is known as attribute reduction or feature selection. This paper proposes a genetic algorithm (GA)based features selection to improve the accuracy of medical data classification. The main purpose of the proposed method is to select the significant feature subset which gives the higher classification accuracy with the different classifiers. The proposed genetic algorithmbased feature selection removes the irrelevant features and selects the relevant features from original dataset in order to improve the performance of the classifiers in terms of time to build the model, reduced dimension and increased accuracy. The proposed method is implemented using MATLAB and tested using the medical dataset with various classifiers namely Naive Bayes, J48, and kNN and it is evident that the proposed method outperforms other methods compared.
Differential Response to Combined Treatment in Patients With Psychotic Versus Nonpsychotic Major Depression

Research has demonstrated that depressed patients with psychotic features show poorer outcomes when treated with pharmacotherapy alone compared with those without psychotic features. However, research has not investigated whether this differential response also applies to combined treatment that includes pharmacotherapy and psychotherapy. In the current study, data were pooled from two clinical trials in which patients diagnosed with major depressive disorder with or without psychotic features were treated with combined treatment. Although similar in severity at pretreatment, results indicated that patients with psychotic depression showed a poorer response in terms of depression severity at postoutpatient treatment and at 6-month follow-up compared with those with nonpsychotic depression. Following treatment, patients with psychotic depression were over four times as likely to exhibit high levels of depression and suicidal ideation. Current state-of-the-art combined treatments have poorer efficacy in depressed patients with psychotic symptoms, and adapted treatment approaches are needed.
FULLY AUTONOMOUS OBSERVATION OF BREAKWATERS BY AN AUV AT KAMAISHI BAY

This paper proposes a robust navigation method for Autonomous Underwater Vehicles (AUVs) operating around structures such as harbors and breakwaters. This method consists of a state estimator and a motion controller, enabling localization in the configuration map as well as following pre-given waypoints without any external help. The state estimator is based on a “particle filter” where the vehicle’s state, horizontal position and heading, is stochastically updated in real time using multi-sensor data. This method was actually implemented to a testbed AUV “Tri-Dog 1” and a series of sea trials were carried out around breakwater caissons at the mouth of Kamaishi bay in Japan. This is the first time an AUV has succeeded in fully autonomous observation around breakwater caissons. Mosaics of the foot protection blocks, rock mound and caisson’s surface are made from the observed images based on the estimated state of the AUV, to verify the performance of the method.
The two-phase twisted-ring counter circuit

The behavior of the two-phase twisted-ring counter (2P-TRC) circuit is analyzed. The circuit produces two individual phased clock signals that exercise a phase difference equal to the half period of the clock. A tree-like structure is built by applying the phased outputs of the circuit to the clock inputs of two replicas of the circuit in order to extend its behavior. The EXOR gate is used to define a mirroring structure attached to the 2P-TRC structure such that a primitive/expanded counter configuration is formed. A fundamental concept being described by the transposition mechanism of the EXOR operator is incorporated to the above configuration such that the phase association of interconnecting signals is preserved.
Power management of a hybrid energy storage system in a domestic microgrid

This paper presents a power control strategy for a grid connected domestic PV system included hybrid energy storage devices. The strategy aims to minimize utility grid dependency of the users in addition to considering safe working conditions of the storage devices. Battery and ultracapacitor were used respectively for providing high energy density and high power density in hybrid storage system. The proposed model was tested in Matlab/Simulink simulation environment by using measurement values which are presented in literature for PV electric generation and domestic energy consumption. Simulation results reveal that domestic demand is exactly supplied by the hybrid storage system as long as ultracapacitor has stored energy. After the energy stored in ultracapacitor is consumed, battery blanks sustain to support utility grid for meeting the demand.
Development of the Chondrocranium of the Loggerhead Turtle, Caretta caretta

Abstract To better understand the evolution and development of the amniote cranium, it is necessary to examine non-avian, non-mammalian embryos. Herein, development of the chondrocranium in the loggerhead turtle, Caretta caretta, is described based on whole-mount and sectioned specimens. Primitive characteristics were found to be established rather early in development; at these stages, the cranium resembled not only the early amniote chondrocrania, but also those of anamniote embryos. Several characteristics were noted in the late chondrocranium that represent shared, derived characteristics of chelonians. In particular, one amniote-specific characteristic, the tropibasic trabecula, appeared at an intermediate stage of development. In addition, developmental changes in the orbital cartilage were reemphasized, and the morphological significance of the crista sellaris was discussed in terms of the basic architecture of the vertebrate neurocranium.
Magnetic Resonance Angiography of Aortic Diseases in Children

Magnetic resonance angiography (MRA), a non-invasive, radiation-free imaging technique dependent on the body’s natural magnetic properties in blood vessels, investigates abnormalities within the aorta. MRA is generally divided into Gadolinium (Gd) based contrast enhanced MRA (CE-MRA) and non-contrast enhanced MRA (NCE-MRA), used for both qualitative and quantitative assessment of the aorta. These sequences can be exemplified with a variety of aortic abnormalities including aortic dissection, coarctation of the aorta, genetic disorders with aortic pathologies (e.g., Marfan’s syndrome, Loeys-Dietz syndrome), ascending and descending aortic aneurysms, Takayasu Arteritis, and various anomalies concerning the aortic arch as well as the aortic valve. While MRA can be applied to nearly any vessel in the body, the primary objective of this chapter is to focus on the role of MRA in the accurate quantitative and qualitative assessment of congenital and acquired aortic diseases. In many hospitals, a significant number of patients who are referred to MRA imaging is comprised of patients with aortic diseases, especially coarctation of aorta [Taylor, 2008]. The diagnostic utility of MRA is illustrated by a variety of pediatric aortic abnormalities.
The recycling itinerary of the 46 kDa mannose 6-phosphate receptor--Golgi to late endosomes--coincides with that of the 215 kDa M6PR.

The intracellular distribution and trafficking of the 46 kDa mannose 6-phosphate (M6PR) receptor has been investigated in rat Clone 9 hepatocytes and NRK cells and compared to that of the 215 kDa M6PR. Antibodies were generated to a synthetic peptide corresponding to the last 15 amino acids of the C-terminal cytoplasmic domain of the 46 kDa M6PR and used to localize it by immunofluorescence and immunoperoxidase labeling. At steady state the 46 kDa M6PR was concentrated at its presumptive sorting site in the Golgi complex, mainly in middle and trans cisternae. In cells treated with chloroquine or NH4Cl, the receptor was found in swollen multivesicular endosomes as well as in Golgi cisternae. When chloroquine-treated cells were double labeled with antibodies to both the 215 and 46 kDa M6PR, all of the endosomes which contained detectable 46 kDa also contained 215 kDa receptor. Thus, after weak base treatment, the 46 kDa receptor is located in a compartment which corresponds to the delivery site of the 215 kDa receptor, previously identified as a late endosome (Woods, J. W., J. Goodhouse, M. G. Farquhar, Eur. J. Cell Biol. 50, 132-143 (1989]. We conclude that the intracellular itinerary of the 46 kDa M6PR is similar to that of the 215 kDa M6PR in that both receptors cycle between the Golgi complex and the same population of late endosomes (prelysosomes). However, the distribution of the two receptors along the recycling route varies under identical conditions in these two cell types. (ABSTRACT TRUNCATED AT 250 WORDS)
Information technology, efficiency and productivity: evidence from Korean local governments

This study evaluates the performance of Korean local government by measuring their technical efficiency (TE) and total factor productivity (TFP) growth and, more importantly, examining the impact of information technology (IT) on this performance. The study is different from received analysis in that a unique measure of the state of IT–the Informatization Index–is used to investigate the impact of IT on both TE and TFP growth. Empirical analyses are conducted on data from 222 Korean local governments for the period 1999 to 2001. In particular, data envelopment analysis techniques are applied to calculate TE scores and TFP growth rates for sampled local governments. The empirical findings confirm the positive impact IT has in improving technical efficiency and accelerating productivity growth. The estimated coefficients are correctly signed (with other regional characteristics controlled for) when TE scores and TFP growth rates are regressed on the Index. In addition, the findings indicate that economies of density are present in the production of local public services.
Look Before You Leap

Simple decisions require the processing and evaluation of perceptual and cognitive information, the formation of a decision, and often the execution of a motor response. This process involves the accumulation of evidence over time until a particular choice reaches a decision threshold. Using a random-dot-motion stimulus, we showed that simply delaying responses after the stimulus offset can almost double accuracy, even in the absence of new incoming visual information. However, under conditions in which the otherwise blank interval was filled with a sensory mask or concurrent working memory load was high, performance gains were lost. Further, memory and perception showed equivalent rates of evidence accumulation, suggesting a high-capacity memory store. We propose an account of continued evidence accumulation by sequential sampling from a simultaneously decaying memory trace. Memories typically decay with time, hence immediate inquiry trumps later recall from memory. However, the results we report here show the inverse: Inspecting a memory trumps viewing the actual object.
Direct reverse transcriptase PCR to determine virulence potential of influenza A viruses in birds

A reverse transcriptase PCR (RT-PCR) was used for rapid determination of the hemagglutinin (HA) cleavage site sequence, a marker for the virulence potential of avian influenza viruses. When applied to specimens from chickens experimentally infected with either a virulent or an avirulent virus, RT-PCR uniformly detected the HA gene, even in specimens that were negative for virus by standard testing in eggs. This technique, combined with sequencing of the HA cleavage site, offers a rapid and sensitive way to assess the virulence potential of avian influenza viruses. Early detection of field isolates with virulence-associated structural motifs at the HA cleavage site would allow better control of influenza among large poultry populations.
Automated sonographic tubal patency evaluation with three‐dimensional coded contrast imaging (CCI) during hysterosalpingo‐contrast sonography (HyCoSy)

Evaluation of tubal status is one of the initial steps in the diagnostic work-up of infertile women. Hysterosalpingo- contrast sonography (HyCoSy), currently performed as part of the infertility work-up to assess tubal patency by transvaginal ultrasound (TVS) 1 , is based on the introduction of fluid into the uterine cavity and Fallopian tubes. To evaluate the Fallopian tubes, a sonographic enhancing positive-contrast medium may be used. Air, albumin with micro air bubbles, and galactose with micro air bubbles have been studied. These positive- contrast agents outline the course of the Fallopian tubes, producingahyperechoicappearance.Themostsimpleand inexpensive positive-contrast medium is saline solution mixed with air. When this solution is shaken, it generates as uspension of air bubbles that is easily identif ied sonographically when injected into the uterine cavity and Fallopian tubes 2-4 with spillage around the ovaries. However, while two-dimensional (2D) TVS HyCoSy with saline solution mixed with air appears to be an accurate and inexpensive screening tool to assess tubal patency, it is highly observer-dependent and is accurate only in the hands of experienced investigators 2-5 . In addition,
Histidine Biosynthesis

Histidine (His) is one of the standard amino acids in proteins, and plays a critical role in plant growth and development. The chemical properties of the imidazole side group allow His to participate in acid-base catalysis, and in the co-ordination of metal ions. Despite the biological importance of this molecule, His biosynthesis has been somewhat neglected in plants, in stark contrast to micro-organisms where the study of this pathway was fundamental in the discovery of operon structure and regulation by attenuation. With the recent isolation of histidinol-phosphate phosphatase, all the enzymes of His biosynthesis have now been identified in Arabidopsis, and several lines of evidence have implicated ATP-phosphoribosyl transferase (which catalyses the first committed step of the pathway) as playing an important role in the regulation of this pathway. However, little is known about the transcriptional regulation of the His biosynthetic genes, nor how demand for this amino acid is balanced with other metabolic requirements in plants. Similarly, the pathway of His catabolism has yet to be determined.
Deep web data extraction

Current automatic wrappers using DOM tree and visual properties of data records to extract the required information from the deep web generally have limitations such as the inability to check the similarity of tree structures accurately. Our study shows that data records located in the deep web do not only share similar visual properties and tree structures, but they are also related semantically in their contents. As such we are able to propose an ontological technique using existing lexical database for English (WordNet) for the extraction of data records from deep web pages. Wrappers designed based on ontological technique are able to reduce the number of potential data regions identified for data extraction, thus improve the data extraction accuracy. In this study, we use visual cue from the underlying browser rendering engine to locate and extract the relevant data region from the deep web by measuring the text and image sizes of data records. Experimental results show that our technique is robust and performs better than the existing state of the art wrappers. Unlike existing ontological based wrappers, our wrapper is domain independent and is able to extract wide range of data records with different structures.
Menarcheal and pubertal development and determining factors among schoolgirls in Kumasi, Ghana

To determine menarcheal and pubertal ages and possible factors responsible for current pubertal trends in Kumasi, Ghana, a cross-sectional study was conducted among 720 urban and rural Kumasi 7–17-year-old schoolgirls and their mothers in 2008. Heights and weights were measured and additional information obtained by survey. Mantel–Haenzsel, χ2, ordered logistic regression and probit analyses were used to analyse the data collected. With 40.42% menarcheal prevalence, median menarcheal ages were significantly different: 12.37 ± 1.48 years urban and 13.41 ± 2.25 years rural; 12.89 ± 1.93 years, overall. Obesity (OR = 2.57; p = 0.033) and high socioeconomic status (OR = 2.12; p = 0.008) were predictors of early menarche, while a younger mother was protective against early menarche (OR = 0.32; p = 0.039). Age at menarche among Kumasi schoolgirls has dropped 0.76 years since it was last determined among similarly aged girls in 1986, declining at a rate of about 0.32 years/decade. The predicting factors provide an important opportunity for intervention through school curricula and targeted education of adolescents.
