The concurrent validity of the Hare psychopathy checklist, youth version in high-risk adolescent females

The present study seeks to expand our understanding of psychopathy in female youth by examining how the relationship between psychopathic traits and aggressive and antisocial behavior may be moderated by gender. The Hare Psychopathy Checklist, Youth Version (PCL:YV) was administered to a clinical sample of 129 adolescent males and females. Regression analyses were run to assess main and interaction effects of gender and psychopathy on aggressive and antisocial behaviors. Scores on the PCL:YV were associated in expected ways with aggression and criminality, and these relationships were largely equivalent across gender. Deficits in affect emerged as a particularly important factor in aggressive conduct among this sample of adolescents. The current study offers preliminary evidence for the concurrent validity of the PCL:YV in female youth, and suggests that this measure may operate comparably in adolescent males and females. Results are discussed in the context of the characteristics of at-risk aggressive youth.

catena-Poly[[[bis(nitrato-κO)copper(II)]-bis[μ-1,3-bis(imidazol-1-yl)-5-methylbenzene-κ2 N 3:N 3′]] dihydrate]

In the title complex, {[Cu(NO3)2(C13H12N4)2]·2H2O}n, the CuII atom is located on a crystallographic center of symmetry and adopts an N4O2 octahedral coordination geometry with four imidazole N atoms in the equatorial sites and two O atoms in the axial sites. The dihedral angles between the central benzene ring and the imidazole rings are 4.93 (11) and 46.08 (12)°. The 1,3-bis(imidazol-1-yl)-5-methylbenzene ligand is bis-monodentate, linking symmetry-related CuII atoms into sheets in the bc plane. These sheets are further bridged into a three-dimensional supramolecular structure by O—H⋯O and C—H⋯O hydrogen bonds.
Foxa1 and Foxa2 regulate multiple phases of midbrain dopaminergic neuron development in a dosage-dependent manner

The role of transcription factors in regulating the development of midbrain dopaminergic (mDA) neurons is intensively studied owing to the involvement of these neurons in diverse neurological disorders. Here we demonstrate novel roles for the forkhead/winged helix transcription factors Foxa1 and Foxa2 in the specification and differentiation of mDA neurons by analysing the phenotype of Foxa1 and Foxa2 single- and double-mutant mouse embryos. During specification, Foxa1 and Foxa2 regulate the extent of neurogenesis in mDA progenitors by positively regulating Ngn2 (Neurog2) expression. Subsequently, Foxa1 and Foxa2 regulate the expression of Nurr1 (Nr4a2) and engrailed 1 in immature neurons and the expression of aromatic l-amino acid decarboxylase and tyrosine hydroxylase in mature neurons during early and late differentiation of midbrain dopaminergic neurons. Interestingly, genetic evidence indicates that these functions require different gene dosages of Foxa1 and Foxa2. Altogether, our results demonstrate that Foxa1 and Foxa2 regulate multiple phases of midbrain dopaminergic neuron development in a dosage-dependent manner.
Cardiometabolic Risk in Hyperlipidemic Men and Women

Objective. The aim of this study was to evaluate sex specific differences of metabolic and clinical characteristics of treated hyperlipidemic men and women (HL-men and HL-women). Methods. In this study vascular and metabolic characteristics of 35 HL-women and 64 HL-men were assessed. In addition a sex specific analysis of metabolic and nutritional habits of HL-patients with prediabetes (HL-IGR) was done. Results. HL-women were older and had favourable concentrations of high density lipoprotein cholesterol (HDL-cholesterol), triglycerides (TG), and triglyceride/HDL-cholesterol ratio (TG/HDL-ratio) but were also shown to have higher concentrations of lipoprotein-a compared to HL-men. HL-men were characterized as having higher levels of liver-specific parameters and body weight as well as being more physically active compared to HL-women. Brain natriuretic peptide (pro-BNP) was higher in HL-women than HL-men, while no differences in metabolic syndrome and glycemic parameters were shown. HL-IGR-women were also older and still had a better profile of sex specific lipid parameters, as well as a lower body weight compared to HL-IGR-men. No differences were seen in vascular parameters such as the intima media thickness (IMT). Conclusion. HL-women were older and had overall more favourable concentrations of lipid parameters and liver enzymes but did not differ regarding vascular morphology and insulin sensitivity compared to HL-men of comparable body mass index (BMI).
Using Multiview Recognition to Guide a Robot ' s Attention

In the transition from industrial to service robotics, robots will have to deal with increasingly unpredictable and variable environments. We present a system that is able to recognize objects of a certain class in an image and to identify their parts for potential interactions. The method can recognize objects from arbitrary viewpoints and generalizes to instances that have never been observed during training, even if they are partially occluded and appear against cluttered backgrounds. Our approach builds on the Implicit Shape Model of Leibe et al. We extend it to couple recognition to the provision of meta-data useful for a task and to the case of multiple viewpoints by integrating it with the dense multi-view correspondence finder of Ferrari et al. Metadata can be part labels but also depth estimates, information on material types, or any other pixelwise annotation. We present experimental results on wheelchairs, cars, and motorbikes. http://mc.manuscriptcentral. com/ijrr International Journal of Robotics Research
Algorithm by Fusion of a Camera and a 3 D Laser Range Finder

In this paper, we propose a system which reconstructs the environment with both color and 3D information. We perform extrinsic calibration of a camera and a LRF (Laser Range Finder) to fuse 3D information and color information of objects. We also formularize an equation to measure the result of the calibration. Moreover, we acquire 3D data by rotating 2D LRF with camera, and use ICP (Iterative Closest Point) algorithm to combine data acquired in other places. We use the SIFT (Scale Invariant Feature Transform) matching for the initial estimation of ICP algorithm. It offers accurate and stable initial estimation robust to motion change compare to odometry. We also modify the ICP algorithm using color information. Computation time of ICP algorithm can be reduced by using color information.
Detecting Earnings Management Using Discontinuity Evidence

Evidence of earnings management based on discontinuities in earnings distributions at prominent benchmarks is pervasive, yet there is little evidence of earnings management based on tests for abnormal accruals. Together with previous results on the characteristics of accrualsbased tests, results in this paper on the statistical characteristics of discontinuity tests reconcile this apparent inconsistency. The distribution of the standardized difference statistic is derived, relaxing the Burgstahler and Dichev (1997) assumption that the two components in the numerator of the standardized difference are independent and simulation results confirm that the "correction" introduced into the literature by Beaver, McNichols, and Nelson (2007) is, in fact, incorrect. Simulation results also suggest that the independence assumption is not likely to induce important errors in typical applications. The power of the standardized difference test is evaluated for alternative assumptions about the pattern of earnings management to meet benchmarks. In contrast to results from previous research that suggest accruals tests have reasonable power only in samples where there are high rates and large amounts of accruals management, discontinuity tests have the power to detect far smaller amounts and much lower rates of total earnings management to meet a benchmark.
pTUNES: Runtime parameter adaptation for low-power MAC protocols

We present pTUNES, a framework for runtime adaptation of low-power MAC protocol parameters. The MAC operating parameters bear great influence on the system performance, yet their optimal choice is a function of the current network state. Based on application requirements expressed as network lifetime, end-to-end latency, and end-to-end reliability, pTUNES automatically determines optimized parameter values to adapt to link, topology, and traffic dynamics. To this end, we introduce a flexible modeling approach, separating protocol-dependent from protocol-independent aspects, which facilitates using pTUNES with different MAC protocols, and design an efficient system support that integrates smoothly with the application. To demonstrate its effectiveness, we apply pTUNES to X-MAC and LPP. In a 44-node testbed, pTUNES achieves up to three-fold lifetime gains over static MAC parameters optimized for peak traffic, the latter being current-and almost unavoidable-practice in real deployments. pTUNES promptly reacts to changes in traffic load and link quality, reducing packet loss by 80 % during periods of controlled wireless interference. Moreover, pTUNES helps the routing protocol recover quickly from critical network changes, reducing packet loss by 70 % in a scenario where multiple core routing nodes fail.
Analysis and Dynamics of the Chromosomal Complements of Wild Sparkling-Wine Yeast Strains

ABSTRACT We isolated Saccharomyces cerevisiae yeast strains that are able to carry out the second fermentation of sparkling wine from spontaneously fermenting musts in El Penedès (Spain) by specifically designed selection protocols. All of them (26 strains) showed one of two very similar mitochondrial DNA (mtDNA) restriction patterns, whereas their karyotypes differed. These strains showed high rates of karyotype instability, which were dependent on both the medium and the strain, during vegetative growth. In all cases, the mtDNA restriction pattern was conserved in strains kept under the same conditions. Analysis of different repetitive sequences in their genomes suggested that ribosomal DNA repeats play an important role in the changes in size observed in chromosome XII, whereas SUC genes or Ty elements did not show amplification or transposition processes that could be related to rearrangements of the chromosomes showing these sequences. Karyotype changes also occurred in monosporidic diploid derivatives. We propose that these changes originated mainly from ectopic recombination between repeated sequences interspersed in the genome. None of the rearranged karyotypes provided a selective advantage strong enough to allow the strains to displace the parental strains. The nature and frequency of these changes suggest that they may play an important role in the establishment and maintenance of the genetic diversity observed in S. cerevisiae wild populations.
Creep of N1-Al and Ni-Cr-Al Superalloy Foams

The steady-state creep rate of Ni-base metallic foams, with superalloy composition (in wt. pct) Ni7.8∼9.1Al (relative density, ρ * = 2.5-2.6) and Ni-13.5∼16.6Cr-5.1∼8.9Al (ρ * = 2.8∼3.0), was measured under a range of temperatures (680∼825°C) and applied stresses (0.1∼0.3 MPa), and compared with that of NiAl intermetallic foams (ρ * = 5.3). The stress exponent and activation energy are within the expected range for bulk superalloys. At 825°C, Ni-Cr-Al foams display creep rates lower by ca. a factor 10 as compared to Ni-Al foams, and higher by ca. a factor 10 as compared to the NiAl intermetallic foams. These differences are discussed in terms of foam density and strut material creep resistance.
Morphosyntactic persistence in spoken English: a corpus study at the intersection of variationist sociolinguistics, psycholinguistics, and discourse analysis

Language users are creatures of habit with a tendency to re-use linguistic material that they have produced or heard before. In other words, linguistic patterns and tokens, once used, persist in spoken discourse. The book explores the determinants of this persistence in corpus data of spoken English, drawing on regression analyses of a variety of functional, discourse-functional, cognitive, psycholinguistic, and external factors. In providing a variationist-probabilistic framework for examining the ways in which different internal and external factors influence speakers' linguistic choices, the study ultimately contributes to a theory of how spoken language works.
FPGA implementation of Blokus Duo player using hardware/software co-design

Blokus Duo is an abstract strategy game for two players. In this paper, we describe our FPGA implementation of Blokus Duo player for ICFPT2014 design contest, which is the revised version of the previous design for ICPFT2013 design contest. Our design consists of hardware logic part and software part using soft IP processor. The hardware logic part calculates evaluation value of the board status which is a heavy task for the software part. Our implementation uses recursive Alpha-Beta pruning and iteration deepening algorithm by the software part, which are complex to implement as the hardware logic circuit. The current version of our implementation on Xilinx Artix7 can run at 142MHz. The hardware logic part evaluates about 90,000 nodes in one second at the beginning of the game.
THE CLUBHOUSE MODEL OF COMMUNITY SUPPORT FOR ADULTS WITH MENTAL ILLNESS: AN EMERGING OPPORTUNITY FOR SOCIAL WORK EDUCATION

This article describes the model and its underlying congruence with social work theory and practice. Findings of the National Task Analysis Study of Social Work Practice are presented that suggest an increasingly important role for social workers and social work educators in the continued growth of this practice model.
Evaluating Protection Against Infectious Bronchitis Virus by Clinical Signs, Ciliostasis, Challenge Virus Detection, and Histopathology

SUMMARY In this study, we examined the association among clinical signs, ciliostasis, virus detection, and histopathology for evaluating protection of vaccinated chickens against homologous and heterologous infectious bronchitis virus (IBV) challenge. At 5 days following challenge with IBV, we found a good correlation among clinical signs, ciliostasis in the trachea, challenge virus detection, and microscopic lesions in the trachea, with all four criteria being negative in fully protected birds and positive in fully susceptible birds. In partially protected birds we observed clinical signs and detected challenge virus; however, the ciliated epithelium was intact. In a second experiment, we challenged fully protected, partially protected, and fully susceptible birds with IBV, and then at 5 days postchallenge we gave the birds an opportunistic bacterium intranasally. Twenty Bordetella avium colonies were recovered from one of five fully protected birds, and only five colonies were isolated from two of five partially protected birds without ciliostasis, whereas in birds with ciliostasis, numerous colonies were isolated. Obviously, decreasing IBV infection and replication in the upper respiratory tract will decrease transmission and mutations, leading to variant viruses, and herein we demonstrate that protection of the cilia will decrease secondary bacterial infections, which have been shown to lead to condemnations and increased mortality. Thus, it appears that examining both criteria would be important when evaluating IBV vaccine efficacy.
Recurrent challenges in the evaluation of fibroepithelial lesions.

CONTEXT The morphologic spectrum of mammary fibroepithelial lesions ranges from fibroadenoma, a common benign neoplasm, to phyllodes tumor, an uncommon lesion that can sometimes recur and metastasize. OBJECTIVE To focus on problems encountered in the diagnostic evaluation of fibroepithelial tumors, highlighting the diagnostically relevant morphologic features and providing an update on the immunohistochemical profile and genetic alterations of these rare neoplasms. DATA SOURCES A PubMed search of the English-language literature identified published reports on fibroepithelial lesions, with a special focus on phyllodes tumor. The results and conclusions of these studies form the basis of this review. CONCLUSIONS The distinction between fibroadenoma and phyllodes tumor is usually not problematic, especially in excision specimens. In some cases, however, the diagnostic evaluation of fibroepithelial lesions can be challenging, especially if only limited material is available. Morphologic predictors of local recurrence of phyllodes tumor include cellularity and cytologic atypia, mitotic activity, positive margins, infiltrative borders, fibroproliferative satellite nodules, and past history of fibroadenoma. Predictors of distant metastasis include size, tumor necrosis, and stromal overgrowth. None of these parameters, however, constitutes a definite marker of malignancy. Presently, molecular and immunohistochemical techniques play a limited role in the diagnosis of fibroepithelial lesions.
From humans to robots: The role of cutaneous impairment in human environmental constraint exploitation to inform the design of robotic hands

Human hands are capable of a variety of movements, thanks to their extraordinary biomechanical structure and relying on the richness of human tactile information. Recently, soft robotic hands have opened exciting possibilities and, at the same time, new issues related to planning and control. In this work, we propose to study human strategies in environmental constraint exploitation to grasp objects from a table. We have considered both the case where participants' fingertips were free and with a rigid shell worn on them to understand the role of cutaneous touch. Main kinematic strategies were quantified and classified in an unsupervised manner. The principal strategies appear to be consistent in both experimental conditions, although cluster cardinality differs. Furthermore, as expected, tactile feedback improves both grasp precision and quality performance. Results opens interesting perspective for sensing and control of soft manipulators.
Dephosphorylated C/EBPα Accelerates Cell Proliferation through Sequestering Retinoblastoma Protein

ABSTRACT CCAAT/enhancer-binding protein alpha (C/EBPα) has been previously considered a strong inhibitor of cell proliferation which uses multiple pathways to cause growth arrest. In this paper, we describe a new function of C/EBPα, which is an acceleration of cell proliferation. This new function of C/EBPα is created in proliferating livers by protein phosphatase 2A-mediated dephosphorylation of C/EBPα at Ser193. The Ser193-dephosphorylated C/EBPα interacts with retinoblastoma protein (Rb) independently on E2Fs and sequesters Rb, leading to a reduction of E2F-Rb repressors and to acceleration of proliferation. This new function of C/EBPα requires Rb, since the dephosphorylated C/EBPα does not promote proliferation in Rb-negative cells. We also show that a balance of Rb and Ser193-dephosphorylated C/EBPα determines if the cells are growth arrested or have an increased rate of proliferation. Consistently with these findings, a significant portion of Rb is sequestered into Rb-C/EBPα complexes in proliferating livers, and E2F-Rb complexes are not detectable in these livers. Our data demonstrate a new pathway by which the phosphorylation-dependent switch of biological functions of C/EBPα promotes liver proliferation.
Visual event classification with human like perception

The primary objective of automated motion semantic classification would be to recognizing events in close similarity with human like perception. This work proposes novel modifications to the standard spectral clustering algorithm in enhancing its capacity to capture human like semantics for visual event classification. The proposed novel multi-feature aggregation strategy replicates human like decision making, incorporating the contextual information of features rather than attempting blind fusion of them. The structural alterations introduced in the Laplacian enabled the methodology to alter the scheme of an event to be detected as an anomalous activity similar to human interpretation. Results of the implemented methodology have been demonstrated for experiments conducted on video streams focusing on human motion patterns.
Detecting suicide risk in a pediatric emergency department: development of a brief screening tool.

OBJECTIVE To develop a brief screening tool that will allow emergency department (ED) staff to rapidly and accurately detect suicide risk in child and adolescent patients. DESIGN Cross-sectional survey. Participants. One hundred forty-four children and adolescents, mean age of 13.6 years, presenting to an urban university teaching hospital pediatric ED for primarily psychiatric reasons. Data Collection. As part of a quality improvement initiative, we developed a 14-item screening survey (the Risk of Suicide Questionnaire [RSQ]) that was administered by a triage nurse to all pediatric mental health patients on admission to the ED. All patients were subsequently administered the 30-item Suicide Ideation Questionnaire (SIQ) by a mental health clinician, which served as the criterion standard assessment of suicidality. Other information collected included demographic and clinical characteristics. MAIN OUTCOME MEASURES Sensitivity, specificity, positive predictive value, negative predictive value (NPV), and area under the receiver operating characteristic curve for responses to individual and combinations of RSQ items, relative to determinations of suicidality by the criterion standard SIQ. RESULTS Four of the items from the RSQ had a predictive c statistic of 0.87, a sensitivity of 0.98, and a NPV of 0.97. Little improvement in predictive ability was obtained by including other RSQ items (c statistic for the most predictive 4-item model = 0.87; c statistic for the model containing all 14 items = 0.90). Among all possible combinations of 4 RSQ items, the combination of items inquiring about current suicidal behavior, past suicidal ideation, past self-destructive behavior, and current stressors yielded the highest sensitivity (0.98), NPV (0.97), and c statistic (0.87), as assessed by the criterion standard SIQ. CONCLUSIONS A brief 4-item screening tool can be used by nonmental health clinicians to accurately detect suicidality in children and adolescents who visit an ED. Early and accurate identification of suicidality is a critical first step that could lead to better treatment and improved health outcomes for children and adolescents with mental health concerns.
