Nuclear confrontation between the United States and the former Soviet Union is less likely now that political tensions have eased and a large portion of their nuclear arsenals are being dismantled. However, negative ramifications of dismantlement have raised the specter of nuclear proliferation in a new and dangerous arena: nuclear terrorism. As a result of warhead dismantlement, stockpiles of ...

The citrus blackfly Aleurocanthus woglumi Ashby 1915 (Hemiptera: Aleyrodidae) is an important insect species native to southwest Asia and represents one of the main pests of citrus plants. It is widely distributed in the tropical and subtropical regions of the globe (Heu and Nagamine, 2001). In Brazil, A. woglumi was first reported in the state of Pará in 2001 (Silva, 2005). Since then, the pre...

BACKGROUND Reducing the urinary sodium-to-potassium ratio is important for reducing both blood pressure and risk of cardiovascular disease. Among free-living Japanese individuals, we carried out a randomized trial to clarify the effect of lifestyle modification for lowering urinary sodium-to-potassium ratio using a self-monitoring device. METHODS This was an open, prospective, parallel random...

f T f a m t o q t . INTRODUCTION n the past decade, spatial solitons (SSs) supported by hotorefractive effect have attracted much attention. he photorefractive effect is a saturable nonlinearity that an support oneor two-dimensional optical SSs at a very ow (microwatts) power level. Interesting discoveries, uch as self-trapping of incoherent white light, interacion of the SSs, self-trapping of ...

The FPGA technology mapping and synthesis problem for combinational circuits has been well studied. But for sequential circuits, most of the previous synthesis and mapping algorithms assume that the positions of ippops are xed and synthesize each combinational block independently. Retiming is a technique to reduce the clock period by repositioning ippops LeSa91]. With retiming, the previous map...

Epilepsy is a disorder of the brain characterised by un-provoked, recurrent seizures and affects about 1% of the population worldwide. A deeper understanding of the cellular basis of the epilepsies would be essential for the identification of novel targets for therapeutic intervention. Since neuronal hyperexcitation and hypersynchronization are hallmarks of epilepsy, the search for new antiepil...
