—This paper identifies a new security problem of existing scheduling algorithms for barrier-coverage of sensors, which never considered before. A barrier-cover of wireless sensors is a subset of sensors seamlessly spanning between two opposite sides such that no intruder can move from one side to the other without being detected. The goal of the scheduling(More)
Candida albicans colonization is required for invasive disease. Unlike humans, adult mice with mature intact gut microbiota are resistant to C. albicans gastrointestinal (GI) colonization, but the factors that promote C. albicans colonization resistance are unknown. Here we demonstrate that commensal anaerobic bacteria-specifically clostridial Firmicutes(More)
Owing to the presence of multiple obstacles or changes in the positions of surroundings objects, the localization of a mobile robot using only natural landmarks is difficult in indoor environments. Consequently, in these environments, the use of artificial landmarks to achieve robust localization is necessary. To this end, we propose a global localization(More)
There are various localization schemes for autonomous navigation of indoor mobile robots. However, most range sensor-based localization schemes only operate efficiently in environments where the geometric structure is fixed. In other words, localization performance is guaranteed only when the geometric structure of the actual environment matches with the(More)
Given the lack of a complete and comprehensive library of microbial reference genomes, determining the functional profile of diverse microbial communities is challenging. The available functional analysis pipelines lack several key features: (i) an integrated alignment tool, (ii) operon-level analysis, and (iii) the ability to process large datasets. Here(More)
Adult stem cell transplantation (SCT) patients with graft-versus-host-disease (GVHD) exhibit significant disruptions in gut microbial communities. These changes are associated with higher overall mortality and appear to be driven by specific antibiotic therapies. It is unclear whether pediatric SCT patients who develop GVHD exhibit similar(More)
Migration velocity of cell populations in vitro is one of important measurements of cell behaviors. As there are massive amount of cells in one image that share similar characteristics and are highly deformable, it is often computational expensive to track every individual cell. It is also difficult to track cells over a long period of time due to(More)
Background There is marked interest in using DNA based methods to detect antimicrobial resistance (AMR) with targeted polymerase chain reaction (PCR) approaches increasingly being incorporated into clinical care. Whole genome sequencing (WGS) could offer significant advantages over targeted PCR for AMR detection, particularly for species where mutations are(More)
