DEAR LADIES AND GENTLEMEN OF THE American Science Community: As I write this from my troubled home state of Kansas, the State Board of Education is debating once again whether to de-emphasize the theory of evolution. Those in the majority on the Board have stated that they are considering changing the very definition of science to allow for science classes to discuss the merits of intelligent d...

Normal aging is typically characterized by abnormal resting-state functional connectivity (FC), including decreasing connectivity within networks and increasing connectivity between networks, under the assumption that the FC over the scan time was stationary. In fact, the resting-state FC has been shown in recent years to vary over time even within minutes, thus showing the great potential of i...

I review the ways that have been proposed to measure the quark transversity distribution in the nucleon. I then explain a proposal, developed by Xuemin Jin, Jian Tang and myself, to measure transversity through the final state interaction between two mesons (ππ, KK, or πK) produced in the current fragmentation region in deep inelastic scattering on a transversely polarized nucleon.

To determine which of the two known gold sulfides (containing either monoor trivalent gold) are formed by reacting trivalent gold with differnt allotropes o f sulfur, experiments were made using three different sources of sulfur. When trivalent gold in the form of A u 2 ( S 0 4 ) 3 in concen­ trated acid is reacted with electrolytically formed short-chain sulfur, monovalent gold sulfide (A u 2S...

the present study concentrates on the synthesis of au nanoparticles (aunps) using aqueous solution of polyvinylpyrrolidone (pvp) and tetrachloroaurate by different methods as thermal, sonochemical and electrochemical reduction. the pvp has been used as a reducing agent and acts as a stabilizer for au nano particles that obtained as principal product. in all synthesis procedures, the active radi...

First principle calculations were performed using Density functional theory within the local spin density approximation (LSDA) to understand the electronic properties of Au(100)+TBT system and compare the results with Au(100) and bulk Au properties. Band structure, the total DOS and charge density for these materials are calculated. We found that the HOMO for Au(100)+TBT becomes broader than Au...

In this study we suggested a new strategy for drug delivery of 6-thioguanine (6-TG) as a cancer drug by loading of this thiolic drug at a surface of Au nanoparticles. For this goal, we synthesized Au nanoparticle (Au/NPs) by reduction of tetrachloroauric (III) acid solutions by sodium borohydride and characterized Au/NPs by X-ray powder diffraction (XRD), dynamic light scattering (DLS), Ultravi...
