Measures of genetic diversity within and among populations and historical geomorphological data on stream landscapes were used in model simulations based on approximate Bayesian computation (ABC) to examine hypotheses of the relative importance of stream features (geomorphology and age) associated with colonization events and gene flow for coho salmon Oncorhynchus kisutch breeding in recently deglaciated streams (50-240 years b.p.) in Glacier Bay National Park (GBNP), Alaska. Population estimates of genetic diversity including heterozygosity and allelic richness declined significantly and monotonically from the oldest and largest to youngest and smallest GBNP streams...

Latent Semantic Analysis (LSA) is widely used for finding the documents whose semantic is similar to the query of keywords. Although LSA yield promising similar results, the existing LSA algorithms involve lots of unnecessary operations in similarity computation and candidate check during on-line query processing, which is expensive in terms of time cost and cannot efficiently response the query request especially when the dataset becomes large. In this paper, we study the efficiency problem of on-line query processing for LSA towards efficiently searching the similar documents to a given query...

BACKGROUND: Depression has become one of the leading contributors to the global disease burden. Evidence-based treatments for depression are available, but access to them is still limited in some instances. As technology has become more integrated into mental health care, computerized cognitive behavioral therapy (CBT) protocols have become available and have been recently transposed to mobile environments (e.g., smartphones) in the form of "apps." Preliminary research on some depression apps has shown promising results in reducing subthreshold or mild to moderate depressive symptoms...

The eBalance project is based on the idea that serious exergames-i.e., computer gaming systems with an interface that requires physical exertion to play-that are well adapted to users, can become a substantial part of a solution to recognized problems of insufficient engagement in fall-prevention exercise and the high levels of fall-related injuries among older people. This project is carried out as a collaboration between eight older people who have an interest in balance training and met the inclusion criteria of independence in personal activities of daily living, access to and basic knowledge of a computer, four staff working with the rehabilitation of older adults, and an interdisciplinary group of six research coordinators covering the areas of geriatric care and rehabilitation, as well as information technology and computer science...

The purpose of this study was to determine and compare outcomes of two voluntary workplace health management methods: an adapted worksite self-management (WSM) approach and an intensive health monitoring (IM) approach. Research participants were randomly assigned to either the WSM group or the IM group by a computer-generated list (n = 180; 92 WSM and 88 IM). Participants completed baseline, 3 and 12-month follow-up surveys. Individuals receiving workplace WSM and IM improved in self-efficacy and nearly all health behaviors and health status variables after the intervention, compared to before the intervention...

Correctly counting entities is a requirement for analytics tools to function appropriately. The Observational Medical Outcomes Partnership's (OMOP) Common Data Model (CDM) specifications were examined to assess the extent to which counting in OMOP CDM compatible data repositories would work as expected. To that end, constructs (tables, fields and attributes) defined in the OMOP CDM as well as cardinality constraints and other business rules found in its documentation and related literature were compared to the types of entities and axioms proposed in realism-based ontologies...

INTRODUCTION: The functional significance of coronary artery collateral (CAC) vasculature in humans has been debated for decades and this has been compounded by the lack of a standard, systematic, objective method of grading and documenting CAC flow in man. CACs serve as alternative conduits for blood in obstructive coronary artery disease. This study aimed to evaluate the impact of CACs on left ventricular function in the presence of total coronary arterial occlusion. METHODS: The study group included the coronary angiographic records of 97 patients (mean age: 59 ± 8 years)...

Nasal turbinates are embryologically derived from a series of outgrowths from the foetal lateral nasal wall. These outgrowths form a series of ridges, referred to as "ethmoturbinals" and have several vital functions. Several different turbinate variations have been reported so far. The authors presented 3 patients of coronal clefted concha who were diagnosed with magnetic resonance imaging. Computed tomography scans and nasal endoscopic examinations are also performed subsequently. These patients are the first coronal clefted concha cases in the literature and also the first radiological study defining concha cleft...

Synchronous bilateral breast cancer is rare, and oncocytic carcinoma is an even rarer breast cancer histological subtype. In general, oncocytic tumors are defined as neoplasms with eosinophilic granular cytoplasm and have been reported in various organs. Oncocytic carcinoma of the breast was first documented by Gădăleanu and Craciun in 1987, and 48 cases have since been reported. The present study reports a case of synchronous bilateral breast oncocytic carcinoma. The patient was a 78-year-old woman. Although she exhibited no symptoms, chest computed tomography revealed three multinodular breast tumors: Two in the right breast and one in the left...

Nitrobenzene is the simplest nitroaromatic compound and yet is characterized by a challenging and rich photophysics and photochemistry. In the present contribution, the main decay paths undertaken by the system after UV absorption from both the brightest (1)(Laππ*) and the lowest (1)(nAπ*) singlet excited states have been characterized by means of CASPT2//CASSCF computations. The obtained results match with the main photophysical properties experimentally reported: the lack of fluorescence and phosphorescence emission is justified by the presence of accessible conical intersections and intersystem crossing regions between, respectively, the (1)(nAπ*) and (3)(nAπ*) states and the ground state, while the high triplet quantum yield is attributable to the strong coupling between the (1)(nAπ*) and (3)(πOπ*) states along the main decay path of the former...

BACKGROUND: In medical practice today, clinical data registries have become a powerful tool for measuring and driving quality improvement, especially among multicenter projects. Registries face the known problem of trying to create dependable and clear metrics from electronic medical records data, which are typically scattered and often based on unreliable data sources. The Society for Thoracic Surgery (STS) is one such example, and it supports manually collected data by trained clinical staff in an effort to obtain the highest-fidelity data possible...

The need for developing effective telehealth tools for dysphagia management is high not only for people who live in rural areas, but also for individuals with mobility/access limitations. We aimed to develop an electronic case History Tool/form (thereafter, e-HiT) for dysphagia, and compare its effectiveness with its paper-based version (PBV) on completion time, completeness, independence, and patient perceptions/satisfaction. Secondarily, we examined associations between the aforementioned variables and predictor variables, such as age, cognition, and computer/internet use...

The increasing growth of literature in biodiversity presents challenges to users who need to discover pertinent information in an efficient and timely manner. In response, text mining techniques offer solutions by facilitating the automated discovery of knowledge from large textual data. An important step in text mining is the recognition of concepts via their linguistic realisation, i.e., terms. However, a given concept may be referred to in text using various synonyms or term variants, making search systems likely to overlook documents mentioning less known variants, which are albeit relevant to a query term...

BACKGROUND: MeSH indexing is the task of assigning relevant MeSH terms based on a manual reading of scholarly publications by human indexers. The task is highly important for improving literature retrieval and many other scientific investigations in biomedical research. Unfortunately, given its manual nature, the process of MeSH indexing is both time-consuming (new articles are not immediately indexed until 2 or 3 months later) and costly (approximately ten dollars per article). In response, automatic indexing by computers has been previously proposed and attempted but remains challenging...

The semantic bootstrapping hypothesis proposes that children acquire their native language through exposure to sentences of the language paired with structured representations of their meaning, whose component substructures can be associated with words and syntactic structures used to express these concepts. The child's task is then to learn a language-specific grammar and lexicon based on (probably contextually ambiguous, possibly somewhat noisy) pairs of sentences and their meaning representations (logical forms)...

BACKGROUND: Family interventions appear to be effective at treating young people's substance misuse. However, implementation of family approaches in UK services is low. This study aimed to demonstrate the feasibility of recruiting young people to an intervention based on an adaptation of adult social behaviour and network therapy. It also sought to involve young people with experience of using substance misuse services in the research process. OBJECTIVES: To demonstrate the feasibility of recruiting young people to family and social network therapy and to explore ways in which young people with experience of using substance misuse services could be involved in a study of this nature...

Development and virtual representation of 3D models of Cultural Heritage (CH) objects has triggered great interest over the past decade. The main reason for this is the rapid development in the fields of photogrammetry and remote sensing, laser scanning, and computer vision. The advantages of using 3D models for restoration, preservation, and documentation of valuable historical and architectural objects have been numerously demonstrated by scientists in the field. Moreover, 3D model visualization in virtual reality has been recognized as an efficient, fast, and easy way of representing a variety of objects worldwide for present-day users, who have stringent requirements and high expectations...
