Since the World Health Organization declared coronavirus disease 2019 (COVID-19) pandemic, lives of all people have significantly changed. These changes range from economic, social, and personal freedom, largely restrictive, while characteristics virus serious widespread repercussions on people's health are not yet fully clarified. In biomedical field, stakeholders scientific researchers strong...

The alpha-beta technique for searching game trees is analyzed, in an attempt to provide some insight into its behavior. The first portion o f this paper is an expository presentation o f the method together with a proof o f its correctness and a historical ch'scussion. The alpha-beta procedure is shown to be optimal in a certain sense, and bounds are obtained for its running time with various k...

Given the increasing popularity of algorithms for overlapping clustering, in particular in social network analysis, quantitative measures are needed to measure the accuracy of a method. Given a set of true clusters, and the set of clusters found by an algorithm, these sets of clusters must be compared to see how similar or different the sets are. A normalized measure is desirable in many contex...

We report a non-equilibrium molecular dynamics (MD) study on heat conduction of finite-length single-walled carbon nanotubes (SWNTs). The length and diameter dependences of the thermal conductivity are quantified for a range of nanotubelengths up to a micrometer at room temperature using two different temperature control techniques. A thorough investigation was carried out on the influence of i...

Developing conceptual and computational frameworks to support Small and Medium Enterprises (SMEs) in formalizing their creativity, improving their capability to innovate, and limiting their drawbacks in tackling wider competitors is an important research topic in the Knowledge Management field. Although these companies are characterized by high levels of creativity, which allow them to design a...

We shed new light on entanglement measures in multipartite quantum systems by taking a computational-complexity approach toward quantifying quantum entanglement with two familiar notions— approximability and distinguishability. Built upon the formal treatment of partial separability, we measure the complexity of an entangled quantum state by determining (i) how hard to approximate it from a fix...

Secure messaging apps have enjoyed huge uptake, and with the headline figure of one billion active WhatsApp users there has been a corresponding burst of academic research on the topic. One might therefore wonder: how far is the academic community from providing concrete, applicable guarantees about the apps that are currently in widespread use? We argue that there are still significant gaps be...

This article looks at six months of the author's repeated attempts to obtain approval three Helsinki Committees (HCs, Israeli hospitals’ research ethics committees) conduct ethnographic with Palestinian physicians in hospitals. While was eventually approved and carried out two these institutions, correspondence HC representatives, as well evidence their informal moves institutions’ management, ...
