Manybody effects in a twocomponent, onedimensional electron gas with repulsive, shortrange interactions
(Elsevier, 19980309)We investigate the correlation effects in a twocomponent, onedimensional electron gas interacting via repulsive δ function interactions. Electron correlations are treated within the approximation scheme of Singwi, Tosi, ... 
Full Visible Range Covering InP/ZnS Nanocrystals with High Photometric Performance and Their Application to White Quantum Dot LightEmitting Diodes
(WileyVCH Verlag, 20120430)Highquality InP/ZnS core–shell nanocrystals with luminescence tunable over the entire visible spectrum have been achieved by a facile onepot solvothermal method. These nanocrystals exhibit high quantum yields (above 60%), ... 
Elementary proofs of some identities of Ramanujan for the RogersRamanujan functions
(Elsevier, 20120401)In a handwritten manuscript published with his lost notebook, Ramanujan stated without proofs forty identities for the RogersRamanujan functions. With one exception all of Ramanujan's identities were proved. In this paper, ... 
BandBending at Buried SiO2/Si Interface as Probed by XPS
(American Chemical Society, 2013)Xray photoelectron spectroscopy is used to probe the photoinduced shifts in the binding energies of Si2p, O1s, and C1s of the SiO2/Si interfaces of a number of samples having oxide and/or thin organic layers on top of ... 
Beaming of light and enhanced transmission via surface modes of photonic crystals
(Optical Society of America, 20051115)We report beaming and enhanced transmission of electromagnetic waves by use of surface corrugated photonic crystals. The modes of a finitesize photonic crystal composed of dielectric rods in free space have been analyzed ... 
Cryptic Torrent Frogs of Myanmar: An Examination of the Amolops marmoratus Species Complex with the Resurrection of Amolops afghanus and the identification of a New Species
(American Society of Ichthyologists and Herpetologists, 2012)We investigated diversity in the Amolops marmoratus species complex within Myanmar using both molecular and morphological characters from recently collected specimens. Based on congruence between multivariate analyses of ... 
Influence of Channel Layer Thickness on the Electrical Performances of InkjetPrinted InGaZn Oxide ThinFilm Transistors
(IEEE, 201102)Inkjetprinted InGaZn oxide (IGZO) thinfilm transistors (TFTs) with bottomgate bottomcontact device architecture are studied in this paper. The impact of the IGZO film thickness on the performance of TFTs is investigated. ... 
On lifting of operators to Hilbert spaces induced by positive selfadjoint operators
(Elsevier, 20050415)We introduce the notion of induced Hilbert spaces for positive unbounded operators and show that the energy spaces associated to several classical boundary value problems for partial differential operators are relevant ... 
Plasmacytoid dendritic cell responses to CpG Odn correlate with CXCL16 expression levels
(Hindawi, 2013)Structurally distinct classes of synthetic CpG oligonucleotides (ODN) differentially activate human immune cells. Ktype ODN trigger plasmacytoid dendritic cells (pDCs) to differentiate and produce TNF alpha. In contrast, ... 
Immunostimulatory activity of polysaccharidepoly(I:C) nanoparticles
(Elsevier, 201106)Immunostimulatory properties of mushroom derived polysaccharides (PS) as standalone agents were tested. Next. PS were nanocomplexed with polyI:C (pIC) to yield stable nanoparticles around 200 nm in size evidenced by atomic ... 
A theorem of Jon F. Carlson on filtrations of modules
(Elsevier, 200701)We give an alternative proof to a theorem of Carlson [J.F. Carlson, Cohomology and induction from elementary abelian subgroups, Quart. J. Math. 51 (2000) 169181] which states that if G is a finite group and k is a field ... 
Coupled plasmonLOphonon modes in GaInAs quantum wires
(American Institute of Physics., 19960620)We study the collective excitation modes of coupled quasionedimensional electron gas and longitudinaloptical phonons in GaInAs quantum wires within the randomphase approximation. In contrast to the higherdimensional ... 
A filtration of the modularrepresentation functor
(Elsevier, 20071201)Let F and K be algebraically closed fields of characteristics p > 0 and 0, respectively. For any finite group G we denote by K RF (G) = K ⊗Z G0 (F G) the modular representation algebra of G over K where G0 (F G) is the ... 
Multigap individual and coupled splitring resonator structures
(Optical Society of America, 2008)We present a systematic numerical study, validated by accompanied experimental data, of individual and coupled split ring resonators (SRRs) of a single rectangular ring with one, two and four gaps. We discuss the behavior ... 
Disorder Induced BCSBEC Crossover in an Ultracold Fermi Gas
(Springer US, 201305)We develop the formalism for BCSBEC crossover in the presence of weak random impurity and calculate the effect of the random potentials on the basic meanfield quantities. The disorder has been included through the Nozieres ... 
Free actions on products of spheres at high dimensions
(Mathematical Sciences Publishers, 20130531)A classical conjecture in transformation group theory states that if G = (Z/p)(r) acts freely on a product of k spheres Sn1 x ... x Snk, then r <= k. We prove this conjecture in the case where the dimensions {n(i)} are ... 
Doping management for highpower fiber lasers: 100 W, fewpicosecond pulse generation from an allfiberintegrated amplifier
(Optical Society of America, 20120716)Thermal effects, which limit the average power, can be minimized by using lowdoped, longer gain fibers, whereas the presence of nonlinear effects requires use of highdoped, shorter fibers to maximize the peak power. We ...
