The different strains of Bacillus cereus can grow at temperatures covering a very diverse range. Some B. cereus strains can grow in chilled food and consequently cause food poisoning. We have identified a new sensor/regulator mechanism involved in low-temperature B. cereus growth. Construction of a mutant of this two-component system enabled us to show that this system, called CasKR, is require...

We introduce a tableau calculus for a nonmonotonic extension of low complexity Description Logic EL that can be used to reason about typicality and defeasible properties. The calculus deals with Left Local knowledge bases in the logic EL⊥Tmin recently introduced in [8] . The calculus performs a twophase computation to check whether a query is minimally entailed from the initial knowledge base. ...

We consider a quantum particle in an infinite square potential well of Rn, n = 2, 3, subjected to a control which is a uniform (in space) electric field. Under the dipolar moment approximation, the wave function solves a PDE of Schrödinger type. We study the spectral controllability in finite time of the linearized system around the ground state. We characterize one necessary condition for spec...

Extreme heat events in the United States are projected to become more frequent and intense as a result of climate change. We investigated the individual and combined effects of land use and warming on the spatial and temporal distribution of daily minimum temperature (Tmin) and daily maximum heat index (HImax) during summer in Houston, Texas. Present-day (2010) and near-future (2040) parcel-lev...

We report the structural and electron transport properties of 3R-Nb1+xS2 (x ≥ .07) and 3R-GaxNbS2 (.1 ≤ x ≤ .33) prepared as polycrystalline pellets as well as single crystals grown by vapour transport. We observe a resistance minimum in these compounds between 20–60 K, with the Tmin proportional to x. The resistance scales as ρ/ρmin(T/Tmin) between .2 < T/Tmin < 2 for different phases with x ≤...

BACKGROUND Lengthy microvascular procedures carry hypothermia risk, yet limited published data evaluate the overall impact of core temperature on patient and flap morbidity. Although hypothermia may contribute to complications, warming measures are challenged by conflicting reports of intraoperative hypothermia improving anastomotic patency. METHODS A retrospective review included all free fl...

In this work we summarize our recent results on extending Description Logics for reasoning about prototypical properties and inheritance with exceptions. First, we focus our attention on the logic ALC. We present a nonmonotonic logic ALC + Tmin, which is built upon a monotonic logic ALC+T obtained by adding a typicality operator T to ALC. The operator T is intended to select the “most normal” o...

OBJECTIVE To explore the associations between the monthly number of dengue fever(DF) cases and possible risk factors in Guangzhou, a subtropical city of China. METHODS The monthly number of DF cases, Breteau Index (BI), and meteorological measures during 2006-2014 recorded in Guangzhou, China, were assessed. A negative binomial regression model was used to evaluate the relationships between B...

Previous findings of time-of-day differences in athletic performance could be confounded by diurnal fluctuations in environmental and behavioral "masking" factors (e.g., sleep, ambient temperature, and energy intake). The purpose of this study was to examine whether there is a circadian rhythm in swim performance that is independent of these masking factors. Experienced swimmers (n = 25) were a...
