HIV-1 Vpu antagonizes the block to particle release mediated by CD317 (BST-2/HM1.24/Tetherin) via incompletely understood mechanisms. Vpu and CD317 partially reside in cholesterol-rich lipid rafts where HIV-1 budding preferentially occurs. Here we find that lipid raft association of ectopically expressed or endogenous CD317 was unaltered upon co-expression with Vpu or following HIV-1 infection. Similarly, Vpu's lipid raft association remained unchanged upon expression of CD317. We identify amino acids V25 and Y29 of Vpu as crucial for microdomain partitioning and single substitution of these amino acids resulted in Vpu variants with markedly reduced or undetectable lipid raft association. These mutations did not affect Vpu's subcellular distribution and binding capacity to CD317, nor its ability to downmodulate cell surface CD317 and promote HIV-1 release from CD317-positive cells. We conclude that (i) lipid raft incorporation is dispensable for Vpu-mediated CD317 antagonism and (ii) Vpu does not antagonize CD317 by extraction from lipid rafts. [less ▲]

This work addresses the problem of data scheduling over fading channels in a deadline (strict delay) constrained multiuser system where a certain amount of data loss can be tolerated. We propose a scheme which schedules the users based on their instantaneous channel conditions and backlog of the packets stored in the buffer. The scheme is analyzed in large user limit. Numerical results demonstrate the energy-performance trade-offs and quantify the gain in energy efficiency for the proposed scheme. [less ▲]

This work considers the scheduling problem for the packets with strict maximum tolerable delay (deadline) constraint. We discuss a multiuser scheduling scheme which schedules the users based on their instantaneous channel conditions, packet deadline and backlog of the buffered packets. The scheme is analyzed in large system limit for the single and multicell cases. The aim is to minimize the system transmit energy while providing hard deadline guarantees for every packet. We analyze the effect of intercell interference on the deadline delay constrained systems and derive an upper bound on the achievable capacity for a given cell size. Numerical results provide the characterization of the operating region of a deadline delay constrained multicell system as a function of spectral efficiency. [less ▲]

Territoriality is mostly discussed as the political competence to exert control on a certain space, in particular with regard to the nation state. Globalization and European Integration have initiated some debate on this understanding, but cross-cross-border cooperation has rarely been linked to this debate. In these areas enormous political changes have been seen during the recent years. Still, the territorial dimension cannot be addressed, as territoriality as known from nation states is challenging politics. However, the territorial implications are manifold and are increasing throughout Europe. Against this backdrop is conceptual reflection. This paper starts with a brief overview of discussions and the empirical implementation of the territoriality debate. Based on this, the paper attempts to catch up with the political changes – the reflection of cross-border territorialities in a two-fold way. The purpose of this paper is to contribute to this field. First, we propose a methodological approach to study the essential aspects. We study from a conceptual point of view, the dimensions of territoriality in cross-border contexts. These are explored as well as the political-juridical background of cross-border cooperation. Based on this, a C-B-IM-tool (Cross-Border Institutional Mapping) has been introduced, involving three steps: (a) (a1) multi-level mapping of cross-border institutions, (b) (a2) mapping of policy arenas and (c) (a3) mapping of the political topography in the sense of going beyond formalized and codified governance patterns. Secondly, with the example of the Greater Region around Luxembourg, the empirical and conceptual findings on cross-border territoriality are illustrated. We can state an establishing cross-border territoriality that does not replace domestic, state-centric territorialities but that inserts new and complex elements of a multi-level territoriality system.

Let G be a locally compact group, and let U be its unitary representation on a Hilbert space H. Endow the space L(H) of bounded linear operators on H with the weak operator topology. We prove that if U is a measurable map from G to L(H) then it is continuous. This result was known before for separable H. We also prove that the following statement is consistent with ZFC: every measurable homomorphism from a locally compact group into any topological group is continuous. [less ▲]

BACKGROUND: Biological networks provide fundamental insights into the functional characterization of genes and their products, the characterization of DNA-protein interactions, the identification of regulatory mechanisms, and other biological tasks. Due to the experimental and biological complexity, their computational exploitation faces many algorithmic challenges. RESULTS: We introduce novel weighted quasi-biclique problems to identify functional modules in biological networks when represented by bipartite graphs. In difference to previous quasi-biclique problems, we include biological interaction levels by using edge-weighted quasi-bicliques. While we prove that our problems are NP-hard, we also describe IP formulations to compute exact solutions for moderately sized networks. CONCLUSIONS: We verify the effectiveness of our IP solutions using both simulation and empirical data. The simulation shows high quasi-biclique recall rates, and the empirical data corroborate the abilities of our weighted quasi-bicliques in extracting features and recovering missing interactions from biological networks.
