Soybean lectin (SBL) purified from soybean seeds by affinity chromatography strongly bound to Bradyrhizobium japonicum USDA 110 cell surface. This lectin enhanced biofilm formation by B. japonicum in a concentration-dependent manner. Presence of galactose during biofilm formation had different effects in the presence or absence of SBL. Biofilms were completely inhibited in the presence of both ...

The article presents a study of the accuracy of estimating the position coordinates of BAUV (Biomimetic Autonomous Underwater Vehicle) by the extended Kalman filter (EKF) method. The fusion of movement parameters measurements and position coordinates fixes was applied. The movement parameters measurements are carried out by on-board navigation devices, while the position coordinates fixes are d...

Introduction. Gastrointestinal stromal tumor (GIST) in the ileum is an extremely rare cause of recurrent lower gastrointestinal bleeding (GIB). Case Report. An 89-year-old man was admitted with melana. He had extensive PMH of CAD post-CABG/AICD, AAA repair, chronic anemia, myelodysplastic syndrome, lung cancer after resection, and recurrent GIB. Prior EGDs, colonoscopies, and upper device-assis...

Conventional algorithms for diagnosis and treatment of gastrointestinal bleeding (GIB) in patients with nonpulsatile ventricular assist devices (VADs) may take days to perform while patients require transfusions. We developed a new algorithm based on deep overtube-assisted enteroscopy (DOAE) to facilitate a rapid diagnosis and treatment. From 2004 to 2012, 84 patients who underwent VAD placemen...

Relevance-based explanation is a scheme in which partial assignments to Bayesian belief network variables are explanations ( abduc­ tive conclusions). We allow variables to re­ main unassigned in explanations as long as they are irrelevant to the explanation, where irrelevance is defined in terms of statistical in­ dependence. When multiple-valued variables exist in the system, especially when ...

OBJECTIVE To develop a model to predict the bleeding source and identify the cohort amongst patients with acute gastrointestinal bleeding (GIB) who require urgent intervention, including endoscopy. Patients with acute GIB, an unpredictable event, are most commonly evaluated and managed by non-gastroenterologists. Rapid and consistently reliable risk stratification of patients with acute GIB for...

BACKGROUND Peptic ulcer is the most common cause of upper gastrointestinal bleeding (GIB) and nutritional support is a helpful strategy in malnutrition prevention during treatment. As early oral feeding in patients with GIB may shorten hospital stay and decrease costs and risk of infection, the present study was carried out to investigate the effects of early oral feeding on relapse and symptom...

Both EBL and SBL occur in southern Africa and in the Southern African context it will therefore be very important to accurately differentiate between EBL and SBL. The epidemiology, direct and indirect economic impact, diagnosis and most importantly control and eradication of EBL is markedly different to that of SBL. Globally EBL infection may also place severe restrictions on the import and exp...

Sparse Bayesian learning (SBL) has emerged as a fast and competitive method to perform sparse processing. The SBL algorithm, which is developed using a Bayesian framework, approximately solves a non-convex optimization problem using fixed point updates. It provides comparable performance and is significantly faster than convex optimization techniques used in sparse processing. We propose a sign...

This work is a re-examination of the sparse Bayesian learning (SBL) of linear regression models of Tipping (2001) in a high-dimensional setting with a sparse signal. We show that in general the SBL estimator does not recover the sparsity structure of the signal. To remedy this, we propose a hard-thresholded version of the SBL estimator that achieves, for orthogonal design matrices, the nonasymp...
