Dynamic Skyscraper Broadcasts for Video-on-Demand

Skyscraper Broadcasting is a recently proposed statically scheduled broadcast technique for video-on-demand that addresses the network-I/O bottleneck to provide signiicantly superior performance over previous approaches. This paper deenes a scheme for dynamically scheduling the objects that are broadcast on the skyscraper channels. The dynamic broadcasting scheme is designed to provide all clie...

Skyscraper polytopes and realizations of plane triangulations

We give a new proof of Steinitz’s classical theorem in the case of plane triangulations, which allows us to obtain a new general bound on the grid size of the simplicial polytope realizing a given triangulation, subexponential in a number of special cases. Formally, we prove that every plane triangulation G with n vertices can be embedded in R in such a way that it is the vertical projection of...

Prevention is a solution: building the HIVe

This Special Issue of Digital Culture and Education (DCE), Building the HIVe, offers relevant and applicable examples of digital technologies being leveraged, positioned and practiced towards communitybased and led HIV prevention as a solution in a digital era. The contributors to this Special Issue, frontline workers, activists, researchers and educators alike, have taken risks as they have ex...

Phenophysiological variation of a bee that regulates hive humidity, but not hive temperature.

Seasonal acclimatisation of thermal tolerance, evaporative water loss and metabolic rate, along with regulation of the hive environment, are key ways whereby hive-based social insects mediate climatic challenges throughout the year, but the relative importance of these traits remains poorly understood. Here, we examined seasonal variation in metabolic rate and evaporative water loss of worker b...
