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...

research on ambidexterity is burgeoning, yet understanding of the antecedents and consequences of both activities remains rather unclear. the purpose of this paper is to explore the effects of knowledge sharing on organizational ambidexterity (exploration and exploitation) as well as the mediating effect of mediating role of absorptive capacity. the research statistical population constitutes 9...

This study examines whether intangible resources such as entrepreneurial capital and collecting donating knowledge contribute to building the absorptive capacity of micro firms achieve innovation. The adopts a mixed-methods approach that follows complementary explanatory design strategy uses dataset 228 from Brazil. main findings are sharing collection influences capacity; has partial mediator ...

The aim of this paper is to highlight the issue of managerial competencies and competency model in industrial enterprises. This paper builds upon the theory of knowledge processing and its role as a theoretical basis for knowledge development in the area of managerial competencies. Managerial competencies are becoming one of the key building blocks of success in a company to achieve both the mi...

Inventors often experience a low productivity after their company has been subject to a merger or acquisition (M&As). It is of central managerial interest to identify factors facilitating the integration of new inventive staff and thereby counteracting innovation declines after M&As. This paper provides empirical evidence into the role of acquiring firms’ absorptive capacity for the post-merger...

background: the role of attenuation in antioxidant capacity or expansion of pro-oxidant/oxidant is well known for the development of stress oxidative. the aim of this study was to evaluate the plasma antioxidant capacity along with uric acid in patients with diabetic nephropathy (dn+) and without diabetic nephropathy (dn-). materials and methods: the research population included 88 patients wit...

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...
