Cadmium sulfide (CdS) is a unique semiconductingmaterial for solar hydrogen generation applications with a tunable, narrowbandgap that straddles water redox potentials. However, its potential towards efficient solar hydrogen generation has not yet been realized due to low photon-tocurrent conversions, high charge carrier recombination and the lack of controlled preparation methods. In this work...

Thermal and non-thermal technologies are both used in the processing and preservation of foods. Recently, awareness about good nutrition coupled with the increasing demand for fresher tasting food have paved theway for new food processing technologies.These include thermalprocessingmethods such asmicrowave (MW), radiofrequency (RF), infrared (IR) heating, pressure-assisted thermal sterilization...

Numerous applications all theway frombiology and physics to economics depend on the density of first crossings over a boundary.Motivated by the lack of general purpose analytical tools for computingfirst-passage time densities (FPTDs) for complex problems, we propose a new simple method based on the independent interval approximation (IIA).We generalise previous formulations of the IIA to inclu...

Westudy to what extend Chinese, Japaneseand Korean faces can be classified and which facial attributes offer the most important cues. First, we propose a novel way of obtaining large numbers of facial images with nationality labels. Then we train state-of-the-art neural networks with these labeled images. We are able to achieve an accuracy of 75.03% in theclassification task, with chancesbeing ...

We consider the space Pn of orthogonal polynomials of degree n on the unit disc for a general radially symmetricweight function.We show that there exists a single orthogonal polynomialwhose rotations through the angles j n+1 , j = 0, 1, . . . , n forms an orthonormal basis for Pn, and compute all such polynomials explicitly. This generalises the orthonormal basis of Logan and Shepp for the Lege...

Funding information Recent technological advances led to the rapid and uncontrolled proliferation of Intelligent Surveillance Systems (ISS), serving to supervise urban areas. Driven by pressing public safety and security requirements, modern cities are transformed into tangled cyber-physical environments, consisting of numerous heterogeneous ISS under different administrative domains with low o...

A tunneling-open failure mode is proposed and carefully studied. A circuit with a tunneling open could pass at-speed Boolean tests but fail VLV testing or I DDQ testing. Theoretical calculations as well as Boolean and I DDQ experiments confirm the existence of tunneling opens. The Murphy experimental data show that seven out of nine VLV-only failure circuits can be explained by this failure mod...

Parliament has finally given approval to the commercial growing of genetically modified (GM) crops across the continent. The vote last month backs a new directive that will end a virtual three-year moratorium on granting licenses for the commercial development of GM foods. The standstill followed concerns about the impact of the new crops on the environment. " This is a significant step in term...
