A constrained least-squares (CLS) 3D source localization method is presented for acoustic sensor networks with sensor position errors. The proposed approach uses angles of arrivals (AOAs) and gain ratios of arrival (GROAs) measured simultaneously at each node to estimate the source position jointly. Compared to AOA-only localization methods, the GROAs can be used in conjunction with AOA measurements so as to get more accurate results by exploiting the geometrical relationship between these two measurements...

The spontaneous folding of flat gel films into tubes is an interesting example of self-assembly. Typically, a rectangular film folds along its short axis when forming a tube; folding along the long axis has been seen only in rare instances when the film is constrained. Here, we report a case where the same free-swelling gel film folds along either its long or short axis depending on the concentration of a solute. Our gels are sandwiches (bilayers) of two layers: a passive layer of cross-linked N,N'-dimethylyacrylamide (DMAA) and an active layer of cross-linked DMAA that also contains chains of the biopolymer alginate...

Epigenetic regulation is achieved at many levels by different factors such as tissue-specific transcription factors, members of the basal transcriptional apparatus, chromatin-binding proteins, and noncoding RNAs. Importantly, chromatin structure dictates the availability of a specific genomic locus for transcriptional activation as well as the efficiency with which transcription can occur. Chromatin immunoprecipitation (ChIP) is a method that allows elucidating gene regulation at the molecular level by assessing if chromatin modifications or proteins are present at a specific locus...

BACKGROUND: Chemotherapy-induced vomiting is a common adverse effect of cancer treatment. We assessed the non-inferiority of palonosetron versus ondansetron in prevention of acute chemotherapy-induced vomiting in children with cancer in 2-18 years of age. METHODS: In this single-center, open-label, randomized study, children receiving moderate and high emetogenic chemotherapy were assigned to get either ondansetron or palonosetron in addition to other antiemetic prophylaxis...

Non-cirrhotic portal hypertension (NCPH) comprises a group of diseases that are characterized by increased portal pressure in the absence of cirrhosis of the liver. It may arise as a result of either primary hepatic disease or the effects of systemic disorders on liver. The natural course of NCPH is largely indolent and benign with an overall better outcome than cirrhosis, as long as the complications of portal hypertension are properly managed and regular surveillance is carried out. However, due to the numerous and variable etiological factors and lack of standardized diagnostic criteria, this entity is under-recognized clinically as well as pathologically and often gets mislabeled as cryptogenic cirrhosis...

Besides the Wenzel state, liquid droplets on micro/nanostructured surfaces can stay in the Cassie state and consequently exhibit intriguing characteristics such as a large contact angle, small contact angle hysteresis and exceptional mobility. Here we report molecular dynamics (MD) simulations of the wetting dynamics of Cassie-state water droplets on nanostructured ultrahydrophobic surfaces with an emphasis on the genesis of the contact line friction (CLF). From an ab initio perspective, CLF can be ascribed to the collective effect of solid-liquid retarding and viscous damping...

Purpose: Primary lacrimal canaliculitis (PLC) is a unique disorder which often gets misdiagnosed by the general as well as speciality-trained ophthalmologists. Elderly patients with history of chronic or recurrent epiphora with discharge, often get mislead towards chronic dacryocystitis. The aim of our report is to discuss the misleading diseases in our PLC patients and to revisit this hidden disease. Methods: The patients of PLC who were previously misdiagnosed were studied...

Background: Following head injury, cardiopulmonary functions are impaired and this disturbs the oxygenation transport pathway. Expanding cardiopulmonary physical therapy to encompass the oxygen transport system as a whole has implication for treatment as well as assessment and treatment outcome. Therefore, the aim of the study is to assess the oxygenation level in head injury patients with relation to body positioning in the intensive care unit (ICU). Methodology: Thirty consecutive patients with head injury with hemodynamically stable were included from the surgical ICU, ages ranging from 15 to 50 years...

Background: Tobacco kills half of its users, with smoking and smokeless tobacco killing nearly 6 million people worldwide - one death every 6 s in each year. Use of tobacco over time causes a physical and psychological addiction due to the presence of nicotine. To find out the level of nicotine dependence among adult (18 years and above) tobacco users and the factors responsible for it. Materials and Methods: A cross-sectional community-based study was conducted among 128 current tobacco users in an urban slum of Burdwan District, West Bengal, India...

Where do new research questions come from? This is at best only partially taught in courses or textbooks about clinical or epidemiological research. Methods are taught under the assumption that a researcher already knows the research question and knows which methods will fit that question. Similarly, the real complexity of the thought processes that lead to a scientific undertaking is almost never described in published papers. In this paper, we first discuss how to get an idea that is worth researching. We describe sources of new ideas and how to foster a creative attitude by "cultivating your thoughts"...

The problem of treating tissue defects of the scalp to date remains one of the actual problems of modern medicine. Low elasticity, stiffness, and the presence of hair follicles and skin deficit dictate the need for new treatments, cosmetic relevant requirements of this zone. The use of expander dermotension in recent years has found its wide distribution in the treatment of defects and deformities of covering tissue anywhere on the body. On the example of a patient K.32 years old hospitalized with diagnosis-basal cell epithelioma of the scalp-the defect of soft tissues, we demonstrated the use of expander plastic in the treatment of defect covering tissues of the scalp...

Introduction: A bacterial infection by Borrelia burgdorferi referred to as Lyme disease (LD) or borreliosis is transmitted mostly by a bite of the tick Ixodes scapularis in the USA and Ixodes ricinus in Europe. Various tests are used for the diagnosis of LD, but their results are often unreliable. We compiled a list of clinically visible and patient-reported symptoms that are associated with LD. Based on this list, we developed a novel scoring system. Methodology: Nutech functional Score (NFS), which is a 43 point positional (every symptom is subgraded and each alternative gets some points according to its position) and directional (moves in direction bad to good) scoring system that assesses the patient's condition...

BACKGROUND: The landscape of smoking cessation may have changed in Europe recently. OBJECTIVES: To identify changes in use of smoking cessation assistance in the European Union (EU) and factors associated with use of cessation assistance. METHODS: Data from the 2012 (n=9921) and 2017 (n=9489) waves of the Eurobarometer survey were used. Self-reported use of smoking cessation assistance was assessed among smokers who had ever tried to quit and former smokers...

Industrial methanol production involves a multi component feed containing methanol, water and trace levels of ethanol being refined to produce AA grade methanol at high product recovery. Due to practical constraints, the bottoms discharge of the column is primarily water with only trace of methanol impurities. As a result of these constraints, ethanol, which is a non-key middle boiling component gets "trapped" near the side draw of the column forming an ethanol bulge, which in turn results in non-linear, inverse, time and state varying behaviour of the side draw ethanol composition...

BACKGROUND: The PACE trial was a well-powered randomised trial designed to examine the efficacy of graded exercise therapy (GET) and cognitive behavioural therapy (CBT) for chronic fatigue syndrome. Reports concluded that both treatments were moderately effective, each leading to recovery in over a fifth of patients. However, the reported analyses did not consistently follow the procedures set out in the published protocol, and it is unclear whether the conclusions are fully justified by the evidence...
