The synthesis and characterization of four fully-conjugated indacenedithiophenes (IDTs) are disclosed. In contrast to anthradithiophenes, regioselective synthesis of both syn and anti isomers is readily achieved. Thiophene fusion imparts increased paratropic character on the central indacene core as predicted by DFT calculations and confirmed by 1H NMR spectroscopy. IDTs exhibit red-shifted abs...

The military is one of the largest pharmaceutical distributors in the country. In order to minimize the amount of inventory held, and hence warehousing and expired drug costs, data mining techniques can be applied to old transaction records to predict future needs. One powerful method of data mining is the use of neural networks. Neural networks have the ability to learn inventory needs based o...

We investigate high-performance, high-frequency interdigital transducers (IDTs) for the generation of surface acoustic waves (SAWs) on GaAs substrates, where the metal fingers are embedded in the substrate. We demonstrate that the acoustic reflections and the scattering of the surface modes into the substrate become considerably reduced in these transducers, leading to an increased output power...

AIMS Craving for the rewarding effects of alcohol may be evoked by conditioned alcohol-like effects whereas conditioned compensatory responses may induce withdrawal relief craving. We tested the hypothesis that drinking in positive emotional states is associated with appetitive reactions to alcohol-associated cues and contributes to reward craving, while conditioned withdrawal is associated wit...

Mitochondria, the energy reactors of the cell, are estimated to contain approximately 1,500 proteins, but the mito-chondrial genome itself only encodes about 13 of them. The remaining proteins are immigrants that are encoded by the nuclear genome. Vamsi Mootha is using an integrative genomics approach to identify all of these proteins and their functions and to understand how their mutated vers...

background: military service is a crucial period in the lives of young people and during this period soldier facing with multiple psychosocial problems. objectives: the present study aimed to explore structural analysis of the relationships between depression, drug abuse, social support and the risk of suicidal ideation among military medical university soldiers in iran. methods: in the present...
