We establish braided tensor equivalences among module categories over the twisted quantum double of a finite group defined by an extension of a group G by an abelian group, with 3-cocycle inflated from a 3-cocycle on G. We also prove that the canonical ribbon structure of the module category of any twisted quantum double of a finite group is preserved by braided tensor equivalences. We give two...

BACKGROUND Healthcare workers are at risk of acquiring viral diseases such as hepatitis B, hepatitis C and HIV through exposure to contaminated blood and body fluids at work. Most often infection occurs when a healthcare worker inadvertently punctures the skin of their hand with a sharp implement that has been used in the treatment of an infected patient, thus bringing the patient's blood into ...

In this paper we study networks based on torus topologies enhanced with additional, arbitrary assigned links. We develop a method for analyzing the expected number of hops which can be applied to any torus topol-ogy with randomly assigned extra links when the simplest greedy routing is used. Using this method, we study the following topologies with extra links: one-dimensional unidirectional an...

Let F be a non-Archimedean locally compact field, let G be a split connected reductive group over F . For a parabolic subgroup Q ⊂ G and a ring L we consider the G-representation on the L-module (∗) C∞(G/Q, L)/ ∑

Draft tube of Francis type hydraulic turbine usually consists of: cone, elbow and diffuser. On the contrary, in some power stations an extra pipe should be added to the draft tube at the bottom of cone because of installation limitation. In this paper, this special case has been numerically studied. To this end CFD analysis was applied to simulate all parts of hydraulic turbine. A homogeneous m...

In this paper we deal with linear systems of P3 through fat points. We consider the behavior of these systems under a cubic Cremona transformation that allows us to produce a class of special systems which we conjecture to be the only ones.

The spring 1996 issue of The Future of Children on special education reviewed the legislative and litigation history of the Individuals with Disabilities Education Act (IDEA). This Revisiting article examines the impact of the two U.S. Supreme Court cases setting forth school districts' responsibility to reimburse parents of students with disabilities for private school tuition under certain ci...
