We have investigated the p-dopant potential of 14 different impurities (Be, B, F, Mg, Al,Ca, Sc, Cu, Zn, Ga, In, Ba, Pt, and Tl) within 4H-SiC via Density Functional Theory (DFT) calcu-lations using a hybrid density functional. analyse incorporation energies impurity atomson Si C sites as well character lattice distortion induced by impurities. The calculatedthermal ionization confirm that Al G...

Heat transfer condensation tests inside a 8 mm ID tube for R-134a, R-410A and R-125 are reported at an average saturation temperature of 40°C, at mass velocities ranging from 65 to 750 kg/(m s), over the entire vapour quality range. After comparing the experimental data against a model able to predict both shear force and gravity driven condensation, a comparison among these fluids has been car...

Projection-reconstruction NMR (PR-NMR) has attracted growing attention as a method for collecting multidimensional NMR data rapidly. The PR-NMR procedure involves measuring lower-dimensional projections of a higher-dimensional spectrum, which are then used for the mathematical reconstruction of the full spectrum. We describe here the program PR-CALC, for the reconstruction of NMR spectra from p...

We discuss the recently proposed Hybrid Backprojection/Lower-Value (HBLV) algorithm and its implementation in the NMR projection-reconstruction software PR-CALC. We argue that the HBLV reconstruction is only suitable for spectra that have no negative peaks. However, in such cases HBLV becomes a straight-forward generalization of the Lower-Value reconstruction algorithm and boils down to a simpl...

Our future military force will be complex: a highly integrated mix of manned and unmanned units. These unmanned units could function individually or within a swarm. The readiness of future warfighters to work alongside and utilize these new forces depends on the creation of usable interfaces and training simulators. The difficulty is that current unmanned aerial vehicle (UAV) control interfaces...

Climatically driven Moran effects have often been invoked as the most likely cause of regionally synchronized outbreaks of insect herbivores without identifying the exact mechanism. However, the degree of match between host plant and larval phenology is crucial for the growth and survival of many spring-feeding pest insects, suggesting that a phenological match/mismatch-driven Moran effect may ...

Scientists and clinicians can utilize a model-based framework to develop computational approaches to psychiatric practice and bring scientifi c discoveries to a clinical interface. This chapter describes a general modeling perspective, which complements those derived in previous chapters, and provides distinct examples to highlight the scientifi c and preclinical research that can evolve out of...

Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women of reproductive age with a prevalence estimated at 4–8% (Azziz et al., 2004; Moran & Teede, 2009). It is associated with a range of reproductive, obstetric, metabolic and psychological features. Reproductive and obstetric manifestations include hyperandrogenism, menstrual dysfunction, infertility and pregnancy complication...
