The concordance of the ΛCDM cosmological model in light current observations has been subject an intense debate recent months. 2018 Planck Cosmic Microwave Background (CMB) temperature anisotropy power spectrum measurements appear at face value to favour a spatially closed Universe with curvature parameter ΩK<0. This preference disappears if Baryon Acoustic Oscillation (BAO) are combined data b...

Sensors in many applications must select the largest element a sequence of currents. This can be performed an analog way by Winner-Take-All (WTA) circuit. paper considers classic version WTA Lazzaro circuit, working with MOS devices subthreshold regime. Since separation gainer analytically computable “decision levels” has recently been introduced, this aims to numerically verify and discuss the...

We consider a number of notice and take-down regimes for Internet content. These differ in the incentives for removal, the legal framework for compelling action, and the speed at which material is removed. By measuring how quickly various types of content are removed, we determine that the requester’s incentives outweigh all other factors, from the penalties available, to the methods used to ob...

Political scientists bring important tools to the analysis of the coronavirus disease 2019 (COVID-19) pandemic, particularly a focus on the crucial role of power in global health politics. We delineate different kinds of power at play during the COVID-19 crisis, showing how a dearth of compulsory, institutional, and epistemic power undermined global cooperation and fuel...

a number of individuals and organizations have considerable influence over the selection of global health priorities and strategies. for some that influence derives from control over financial resources. for others it comes from expertise and claims to moral authority—what can be termed, respectively, epistemic and normative power. in contrast to financial power, we commonly take for granted th...

The power take-off (PTO) damping mechanism is very important to the motion and conversion for wave energy converters. Based upon potential flow theory, series expression with unknown Fourier coefficients of velocity function basin where cylindrical floating buoy located obtained by using eigenfunction expansion method. According characteristics PTO damper, float under linear non-linear are stud...
