The Katz centrality of a node in a complex network is a measure of the node's importance as far as the flow of information across the network is concerned. For ensembles of locally tree-like undirected random graphs, this observable is a random variable. Its full probability distribution is of interest but difficult to…

OBJECTIVE: With its anonymity and accessibility, text-based online counseling has shown great potential in reaching people with mental health needs. One strategy adopted to meet the service gap is, that is, each counselor attending to more than one client at a time. To date, there is no reported evidence supporting its…

The experiences of medical students, residents, and faculty with a computerized literature searching system were evaluated. Third-year medical students, internal medicine and family practice residents, and full-time and voluntary faculty at one medical school had the opportunity to use a full-text and bibliographic med…

PURPOSE: To conduct a systematic review to evaluate the evidence of possible benefits and accuracy of digital impression techniques vs. conventional impression techniques. MATERIALS AND METHODS: Reports of digital impression techniques versus conventional impression techniques were systematically searched for in the f…

Wear-free sliding between two contacted solid surfaces is the ultimate goal in the effort to extend the lifetime of mechanical devices, especially when it comes to inventing new types of micro-electromechanical systems where wear is often a major obstacle. Here we report experimental observations of wear-free sliding f…

Inflicted blunt force trauma and/or repetitive acceleration-deceleration trauma in infants can cause brain injury. Yet, the exact pathophysiologic mechanism with its associated thresholds remains unclear. In this systematic review an overview of animal models for shaking trauma and their findings on tissue damage will…

OBJECTIVE: To measure the effect of free access to the scientific literature on article downloads and citations. DESIGN: Randomised controlled trial. SETTING: 11 journals published by the American Physiological Society. PARTICIPANTS: 1619 research articles and reviews. MAIN OUTCOME MEASURES: Article readership (mea…

Myocardial Infarction (MI) is an obstruction in the coronary arteries, resulting in restricted blood flow and oxygen supply to the heart, leading to damage to the heart's tissues. Beyond the cardiovascular system, the impact of MI extends to potentially affecting cognitive abilities, especially in elderly populati…

Hypercomplex neural networks have proven to reduce the overall number of parameters while ensuring valuable performance by leveraging the properties of Clifford algebras. Recently, hypercomplex linear layers have been further improved by involving efficient parameterized Kronecker products. In this article, we define t…

Between April 20, 2020 and June 19, 2020 we conducted a survey of the membership of the Psychiatric Genomics Consortium (PGC) to explore the impact of COVID-19 on their research and academic careers. A total of 123 individuals responded representing academic ranks from trainee to full professor, tenured and fixed-term…

Systematic review has generally been accepted as an effective, more complete, repeatable, and less biased type literature review that can successfully lead to evidence-based conclusions. This study attempts to develop a framework for systematic review with guidelines on how to conduct an effective systematic review for…

Development of journal collection in the Andrija Stampar library is presented. Research of loaned and photocopied journals was performed in order to evaluate circulation of journals in 2001. There were 1057 titles of journals in the Library, 77 were secondary journals and they were excluded from the study. 346 differen…

India contributes one-third of the global burden of rabies. In 2021, the National Action Plan for Rabies Elimination (NAPRE) was introduced to eliminate dog-mediated human rabies. The major challenges in the path of eliminating dog-mediated rabies are toward achieving the high level of dog vaccination coverage and its…

Text generative models trained via maximum likelihood estimation (MLE) suffer from the notorious exposure bias problem, and generative adversarial networks (GANs) are shown to have potential to tackle this problem. The existing language GANs adopt estimators, such as REINFORCE or continuous relaxations to model word pr…

INTRODUCTION: The present study aimed at all the benefits induced by taking the Mediterranean or Japanese diet among nurses and whether any beneficial differences in intakes between the two diets were considered. METHODS: The author searched PubMed and Embase databases for medical subheadings terms and free full text…

Pleomorphic sarcoma of the tongue base is an extremely rare pathology finding. Our review of current databases returned fewer than 10 articles available free full text on this subject. We review the current state of art management guidelines for this type of tumor. Our case presented surprisingly a favorable evolution…

Meningeal carcinomatosis (MC) is a rare presentation of solid tumors, particularly breast cancer, lung cancer, and malignant melanoma. Recently, the incidence of MC has been reported to be increasing. It has a bad prognosis despite aggressive therapy. The usual clinical presentation is multifocal involvement of the neu…

underpin Evidence Based Medicine (EBM) by addressing precise clinical questions via comprehensive synthesis of all relevant published evidence. Authors of systematic reviews typically define a Population/Problem, Intervention, Comparator, and Outcome (acriteria) of interest, and then retrieve, appraise and synthesize r…

BACKGROUND:  Large defects of the lower lip often require free tissue coverage. Fasciocutaneous free flaps have been traditionally used, but innervated muscular free flaps may fundamentally address orbicularis oris deficiency and improve dynamic competence. This review aimed to determine if innervated muscular f…

BACKGROUND: Even with satisfactory anastomosis technique and adequate experience of the surgeon, flap loss due to thrombosis can still occur due to the patient's underlying condition. Patients with hypercoagulability due to etiologies such as malignancy, hereditary conditions, and acquired thrombophilia are among those…
