In this paper, a distributed cubature Gaussian mixture filter (DCGMF) based on an iterative diffusion strategy (DCGMF-ID) is proposed for multisensor estimation and information fusion. The uncertainties are represented as Gaussian mixtures at each sensor node. A high-degree cubature Kalman filter provides accurate estimation of each Gaussian mixture component. An iterative diffusion scheme is utilized to fuse the mean and covariance of each Gaussian component obtained from each sensor node. The DCGMF-ID extends the conventional diffusion-based fusion strategy by using multiple iterative information exchanges among neighboring sensor nodes...

Purpose To examine the effects of subconcussive impacts resulting from a single season of youth (age range, 8-13 years) football on changes in specific white matter (WM) tracts as detected with diffusion-tensor imaging in the absence of clinically diagnosed concussions. Materials and Methods Head impact data were recorded by using the Head Impact Telemetry system and quantified as the combined-probability risk-weighted cumulative exposure (RWECP). Twenty-five male participants were evaluated for seasonal fractional anisotropy (FA) changes in specific WM tracts: the inferior fronto-occipital fasciculus (IFOF), inferior longitudinal fasciculus, and superior longitudinal fasciculus (SLF)...

A growing percentage of low-income children in the United States come from Spanish-speaking homes and are dual language learners (DLLs). Recent research shows that bilingual children, compared to monolinguals, have enhanced executive functioning (EF), a set of foundational cognitive skills that predict higher social-emotional competence and academic achievement in preschool and beyond. Although this association has been found among children of different backgrounds, no study to date has assessed whether bilingual Latino preschoolers from low-income backgrounds have higher EF than their monolingual peers and their emerging bilingual peers, respectively...

OBJECTIVES: Public health has recognized that nature is good for health but there are calls for a review of its gendered aspects. This review attempts to develop and explore a broad analytical theme - the differing interconnections between gender, health and nature. The paper summarizes the interconnections that have been subject to extensive academic enquiry between gender and health, health and space, and gender and space. METHODS: A combination of key terms including place; gender; health; outdoor space; green space; natural environment; national parks; femininity; masculinity; recreation; physical activity; sustainability; ecofeminism; feminism; environmental degradation; and environmental justice were used to search the electronic databases Sociological Abstracts, Web of Science and Scopus to identify relevant articles...

Sclerostin is an osteocyte derived negative regulator of bone formation. A highly specific expression pattern and the exclusive bone phenotype have made Sclerostin an attractive target for therapeutic intervention in treating metabolic bone diseases such as osteoporosis and in facilitating fracture repair. Understanding the molecular mechanisms that regulate Sclerostin transcription is of great interest as it may unveil new avenues for therapeutic approaches. Such studies may also elucidate how various signaling pathways intersect to modulate bone metabolism...

A complex array of intersecting social contextual factors are known to influence safer and/or unsafe practices among people who inject drugs. However, less is known about the social contextual factors that may specifically influence injection practices for young people who inject drugs. In this qualitative study, we explored with young people, ages 18-29, living in an urban centre in Nova Scotia, Canada, their perceptions and experiences of the social contextual factors that influence their safer and/or unsafe injection practices...

OBJECTIVES: This paper aimed to (i) differentiate the effects of contributory factors on crash risks related to different transportation modes, i.e., motor vehicle, bicycle and pedestrian; (ii) explore the potential contribution of zone-level factors which are traditionally excluded or omitted, so as to track the source of heterogeneous effects of certain risk factors in crash-frequency models by different modes. METHODS: Two analytical methods, i.e. negative binomial models (NB) and random parameters negative binomial models (RPNB), were employed to relate crash frequencies of different transportation modes to a variety of risk factors at intersections...

The role of pesticides in recent honey bee losses is controversial, partly because field studies often fail to detect effects predicted by laboratory studies. This dissonance highlights a critical gap in the field of honey bee toxicology: there exists little mechanistic understanding of the patterns and processes of exposure that link honey bees to pesticides in their environment. We submit that 2 key processes underlie honey bee pesticide exposure: (1) the acquisition of pesticide by foraging bees and (2) the in-hive distribution of pesticide returned by foragers...

Much of the extant scientific research examining hypothalamic-pituitary-adrenal (HPA)-axis functioning is conducted among White heterosexuals. Very little research examines HPA-axis functioning between different minority groups. Individuals who identify as both sexual and racial minorities may experience increased stigma and discrimination that can affect HPA-axis functioning. In the current study, we examined diurnal cortisol rhythm in young White gay men (WGM) compared to young Black gay men (BGM). The sample consisted of 70 healthy gay men (mean [SD] age=22...

Research in the field of pediatric sleep has grown significantly in the past 25 years. However, because much remains to be learned about the complex and dynamic relationship between sleep and developmental psychopathology, this special issue of the Journal of Clinical Child and Adolescent Psychology was created to provide an influx of cutting-edge research on this important topic. This introduction provides an overview of the special issue, with articles focusing on what different measurement approaches tells us about the intersection of sleep and developmental psychopathology; the overlap between interventions for sleep and anxiety; sleep as a potential mechanism for the development of social, emotional, and behavioral problems; and how population-based studies can be used to consider the interaction between sleep, well-being, and symptoms of psychopathology...

To describe a mobile defect in polyacetylene chains, Su, Schrieffer and Heeger formulated a model assuming two degenerate energy configurations that are characterized by two different topological phases. An immediate consequence was the emergence of a soliton-type edge state located at the boundary between two regions of different configurations. Besides giving first insights in the electrical properties of polyacetylene materials, interest in this effect also stems from its close connection to states with fractional charge from relativistic field theory...

Ab initio molecular dynamics (AIMD) simulations were carried out for *-excited 1,1'-dimethylstilbene (dmSB) at the spin-flip time-dependent density functional theory (SF-TDDFT) level with the TSF-index technique, to get insights into the substitution effects on the photoisomerization dynamics of stilbene (SB). It is found that the reaction path from the Franck-Condon structure of cis-dmSB is oriented toward the 4,4-dihydrophenanthrene (DHP) side from the beginning, which is in contrast to the case of SB where the pathway is oriented toward the twist-side in the initial stage...

Although the clinical landscape of melanoma is improving rapidly, metastatic melanoma remains a deadly disease. Age remains one of the greatest risk factors for melanoma, and patients older than 55 have a much poorer prognosis than younger individuals, even when the data are controlled for grade and stage. The reasons for this disparity have not been fully uncovered, but there is some recent evidence that Wnt signalling may have a role. Wnt signalling is known to have roles both in cancer progression as well as in organismal ageing...

OBJECTIVE: A recent HIV outbreak in a rural network of persons who inject drugs (PWID) underscored the intersection of the expanding epidemics of opioid abuse, unsterile injection drug use (IDU), and associated increases in hepatitis C virus (HCV) infections. We sought to identify US communities potentially vulnerable to rapid spread of HIV, if introduced, and new or continuing high rates of HCV infections among PWID. DESIGN: We conducted a multistep analysis to identify indicator variables highly associated with IDU...

OBJECTIVES: Intersectionality theory proposes that each combination of social categories derived from gender, race and nationality, such as immigrant White man or native-born Black woman, is associated with unique social experiences. We tested the potential of intersectionality theory for explicating racial inequalities in Canada by investigating whether Black-White health inequalities are conditioned by gender and immigrant status in a synergistic way. METHODS: Our dataset comprised 10 cycles (2001-2013) of the Canadian Community Health Survey...
