Editorial ajp.psychiatryonline.org A century ago, rapid-cycling bipolar disorder was not observed. Either classic nosol-ogists, such as Kraepelin, simply missed it or it did not exist. The term was first coined in the 1970s to identify lithium nonresponders in randomized clinical trials; thereafter, rapid cycling became the subject of decades of further research, which has confirmed that rapid ...

BACKGROUND Cycling is a recreational activity and mode of commuting with substantial potential to improve public health in many countries around the world. The aim of this study was to examine prospective associations between recreational and commuter cycling, changes in cycling habits, and risk of type 2 diabetes (T2D) in Danish adults from the Diet, Cancer and Health cohort study. METHODS A...

Recent studies have established the existence of substrate cycles in humans, but factors regulating the rate of cycling have not been identified. We have therefore investigated the acute response of glucose/glucose-6P-glucose (glucose) and triglyceride/fatty acid (TG/FA) substrate cycling to the infusion of epinephrine (0.03 microgram/kg.min) and glucagon. The response to a high dose glucagon i...

BACKGROUND Gender differences in cycling are well-documented. However, most analyses of gender differences make broad comparisons, with few studies modeling male and female cycling patterns separately for recreational and transport cycling. This modeling is important, in order to improve our efforts to promote cycling to women and men in countries like Australia with low rates of transport cycl...

Standard packaging and interconnection technologies of power devices have difficulties meeting the increasing thermal demands of new application fields of power electronics devices. Main restrictions are the decreasing reliability of bond-wires and solder layers with increasing junction temperature. In the last few years intensive efforts have been invested in developing new packaging and inter...

We have compared aging phenomena in the Fe0.5Mn0.5T iO3 Ising spin glass and in the CdCr1.7In0.3S4 Heisenberg-like spin glass by means of lowfrequency ac susceptibility measurements. At constant temperature, aging obeys the same ‘ωt scaling’ in both samples as in other systems. Investigating the effect of temperature variations, we find that the Ising sample exhibits rejuvenation and memory eff...

Article history: Received 29 June 2016 Accepted 8 July 2016 Available online 18 September 2016 SiC is a wide bandgap semiconductor with better electrothermal properties than silicon, including higher temperature of operation, higher breakdown voltage, lower losses and the ability to switch at higher frequencies. However, the power cycling performance of SiC devices in traditional silicon packag...

Predators, particularly those living in deserts, use two main foraging strategies, namely sit-andwait or wide foraging. The Moorish gecko Tarentola mauritanica, a gecko frequently inhabiting humanized habitats, has been repeatedly classified as a sit-and-wait predator. However, previous data on dietary composition in natural habitats suggest a wide foraging strategy for this species. This study...

ii The last thermal issue addressed by this thesis is related to temperature cycling. Temperature cycling test procedures are usually applied to safetycritical systems to detect cycling-related early-life failures. Such failures affect advanced SoCs, particularly through-silicon-via structures in 3Dstacked-ICs. An efficient schedule-based cycling-test technique that combines cycling acceleratio...

The paper will give a detailed presentation of an active power cycling test bench in high temperature conditions developed to ageing the solder between the Direct Copper Bonding (DCB) and the base of IGBT devices. The average junction temperature measurement protocol, the temperature regulation of the base plate, the acquisition of all the electrical signals, and the performance of the test cir...
