چکیده
We show that fusion categories Rep(kστT ) of representations of the weak Hopf algebra coming from a vacant double groupoid T and a pair (σ, τ ) of compatible 2-cocyles are group-theoretical.

Management of a severe forceful breather with Rett syndrome using carbogen.
We have used a novel neurophysiological technique in the NeuroScope system in combination with conventional electroencephalography (EEG) to monitor both brainstem and cortical activity simultaneously in real-time in a girl with Rett syndrome. The presenting clinical features in our patient were severe sleep disturbances, irregular breathing in the awake state dominated by Valsalva's type of bre...
متن کاملRural-urban differences in the public health workforce: local health departments in 3 rural Western states.
✖ Rural LHDs are very small, with fewer than 5 working professionals in the average office, compared with nearly 32 in an average urban office. ✖ The per capita public health workforce supply is slightly greater in rural than in urban LHDs (32:100,000 versus 29:100,000). ✖ Public health nurses form the core of rural LHDs; urban LHDs have a wider variety of professional categories represented wi...
متن کاملB. Estimating the Size of the IT Workforce
Estimates of the IT workforce depend, first, on the definition of “IT worker” used. For example, estimating the number of Category 1 IT workers would yield a very different result (Table B.1) than would estimating the combined total of Category 1 and Category 2 workers (Table B.2). Similarly, estimating the number of individuals in software occupations would be a different exercise from estimat...
متن کاملGardening in the desert: a spatial optimization approach to locating gardens in rapidly expanding urban environments
BACKGROUND Food access is a global issue, and for this reason, a wealth of studies are dedicated to understanding the location of food deserts and the benefits of urban gardens. However, few studies have linked these two strands of research together to analyze whether urban gardening activity may be a step forward in addressing issues of access for food desert residents. METHODS The Phoenix, ...
متن کاملThe convex basis of the left null space of the stoichiometric matrix leads to the definition of metabolically meaningful pools.
The stoichiometric matrix, S, represents a mapping of reaction rate vectors into a space of concentration time derivatives. The left null space of the stoichiometric matrix contains the dynamic invariants: a combination of concentration variables, referred to as metabolic pools, whose total concentration does not change over time. By analogy to the traditional reaction map formed by S, a compou...
