Water saturation and cation exchange capacity are the most significant parameters used to calculate a hydrocarbon zone potential. In clean formations, by applying the famous Archie model, which assumes that in the formation the only electric conductor is the formation water, the water saturation can be calculated. Additionally, in shaly sand formations this assumption may not be true as the ion...

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) ...

food safety issues are not a new issue in science, but due to the dynamic changes in the modern world it is as equally important as decades ago. the aim of the study was to address the efforts in the development of a comprehensive food safety system in serbia, and make specific recommendations regarding the improvement of epidemiological investigation capacity as a useful tool which contributes...

within a single tumor clone, cells have significantly different abilities to proliferate and form new tumors. this has led to the hypothesis that most cells in a cancer have a limited ability to divide and only a small subset of distinct cells, the cancer stem cells (cscs), has the capacity to self-renew and form new tumors . it has been proposed that the development of tumors is based exclusiv...

Porous hierarchical NiMn2O4/C tremella-like nanostructures are obtained through a simple solvothermal and calcination method. As the anode of lithium ion batteries (LIBs), porous NiMn2O4/C nanostructures exhibit a superior specific capacity and an excellent long-term cycling performance even at a high current density. The discharge capacity can stabilize at 2130 mA h g(-1) within 350 cycles at ...

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...
