We exhibit a possible road towards a strong converse for the quantum capacity of degradable channels. In particular, we show that all degradable channels obey what we call a “pretty strong” converse: When the code rate increases above the quantum capacity, the fidelity makes a discontinuous jump from 1 to at most 1 √ 2 , asymptotically. A similar result can be shown for the private (classical) ...

The U.S. joint military medical community has an increasing role in collaborative health sector engagement internationally as part of a whole of government approach to successful operations. The military must master the ability to catalyze health sector gains that can be developed by hosts, U.S. Government, and international agencies in both permissive environments and conflict zones. Capacity ...

We study the one-shot zero-error classical capacity of quantum channels assisted by quantum non-signalling correlations, and the reverse problem of simulation. Both lead to simple semi-definite programmings whose solutions can be given in terms of the conditional min-entropies. We show that the asymptotic simulation cost is precisely the conditional min-entropy of the Choi-Jamiołkowski matrix o...

Motivated by channel measurements in different indoor locations we will show that the WLAN indoor MIMO channel is characterized by few dominant transmission paths mainly corresponding to the LOS path and some strong reflections. In the contrary to the common statistical flat Rayleigh fading channel model we will explain that the WLAN channel is widely deterministic and frequency selective. Furt...

one of the most important parameters in evaluating a watermarking algorithm is its capacity. generally, watermarking capacity is expressed by bits per pixel (bpp) unit measure. but this measure does not show what the side effects would be on image quality, watermark robustness and capacity. in this paper we propose a three dimensional measure named capacity surface which shows the effects of ca...

This paper contains a construction for independent sets in the powers of the complements of odd cycles. In particular, we show that α ( C 2 2n+3 ) ≥ 22n + 1. It follows that for n ≥ 0 we have Θ(C2n+3) > 2, where Θ(G) denotes the Shannon capacity of graph G.

The Women's Health Program at the University of Michigan was established in 1993 and has developed into a successful, federally supported program that links clinical research and education activities across the University. It has focused on human resource capacity building, sustainable financial support and infrastructure, and adaptability to change and opportunities. Widely accepted standards,...

Public Health emphasizes the plurality of the determinants of health of individuals, families and communities. Nutrition, as a major determinant of health, is itself influenced by a multitude of determinants that are under the purview of several agencies. Thus, inter-sectoral collaboration among the relevant agencies is imperative for promoting optimal health and nutrition such a partnership is...
