The robust correlation between peer and adolescent alcohol use (AU) has been taken as evidence for both socialization and selection processes in the etiology of adolescent AU. Accumulating evidence from studies using a diverse range of methodological and statistical approaches suggests that both processes are involved. A major challenge in testing whether peer AU predicts an adolescent's drinki...

The spectra of charged hadrons produced near mid-rapidity in d+Au, p+Au and n+Au collisions at p sNN = 200 GeV are presented as a function of transverse momentum and centrality. Thesemeasurements were performed using the PHOBOS detector at the Relativistic Heavy Ion Collider (RHIC). Nucleon-nucleus interactions were extracted from the d+Au data by identifying the deuteron spectators. The deuter...

DMF-stabilized Au nanoparticles (NPs) with three different particle sizes were prepared by controlling the reaction temperatures and times. In the absence of any additional ligands, these Au NPs showed high catalytic activity in the Ullmann homocoupling of aryl iodides in DMF. The effects of Au particle size on the coupling reaction were investigated by the use of three Au catalysts with mean p...

Au-coated vertical silicon nanowire electrode array (VSNEA) was fabricated using a combination of bottom-up and top-down approaches by chemical vapor deposition and complementary metal-oxide-semiconductor process for biomolecule sensing. To verify the feasibility for the detection of biomolecules, Au-coated VSNEA was functionalized using peptides having a fluorescent probe. Cyclic voltammograms...

Water-soluble Ag-Au bimetallic nanostructures were prepared via co-reduction and seed-mediated growth routes employing poly-(4-styrenesulfonic acid-co-maleic acid) (PSSMA) as both a reductant and a stabilizer. Ag-Au alloy nanoparticles were obtained by the co-reduction of AgNO3 and HAuCl4, while Ag-Au core-shell nanostructures were prepared through seed-mediated growth using PSSMA-Au nanopartic...

based on the fact the manipulation of fine nanoclusters calls for more precise modeling, the aim of this paper is to conduct an atomistic investigation for interaction analysis of particle-substrate system for pushing and positioning purposes. in the present research, 2d molecular dynamics simulations have been used to investigate such behaviors. performing the planar simulations can provide a ...

la mémoire involontaire, voilà ce qui permet à l'homme de se dégager des entraves du temps et en ébranler la mainmise. elle est un corridor pour accéder à l'éternité. grâce à elle, l’homme peut échapper à la discontinuité. tout en restant solidement cloué au présent, tout en allant au-devant du futur, il peut remonter le cours de ses ans et parvenir au passé. c'est ainsi que le passé, le présen...

Bimetallic Au-based nanoparticles (Au-M where M = Pt, Pd, Cu, Ni), synthesized by simultaneous reduction of the Au salt with noble/non-noble metal salts, exhibit a high activity for the aminoalkene (2,2-diphenylpent-4-en-1-amine) hydroamination affording the 5-membered Markovnikov product. Even though the particle size and morphology of Au-M nanoparticles are comparable to the corresponding mon...

Abstract. Recent results on high transverse momentum (pT ) hadron production in p+p, d+Au and Au+Au collisions at the Relativistic Heavy Ion Collider (RHIC) are reviewed. Comparison of the nuclear modification factors, RdAu(pT ) and RAA(pT ), demonstrates that the large suppression in central Au+Au collisions is due to strong final-state effects. Theoretical models which incorporate jet quenchi...

BACKGROUND CXCR4 chemokine receptor is constitutively expressed on normal and malignant B lymphocytes derived from patients with B-cell lymphoproliferative disorders and has a significant role in cell migration to lymph nodes and bone marrow. Non-Hodgkin's lymphomas (NHL) constitute a heterogeneous group of lymphoproliferative diseases, which can localize not only to lymph nodes, but also can m...
