We perform numerical simulations, including parallel tempering, a four-state Potts glass model with binary random quenched couplings using the JANUS application-oriented computer. We find and characterize a glassy transition, estimating the critical temperature and the value of the critical exponents. Nevertheless, th…
Abstract In the present study, it was evaluated how two different culture conditions for the biotreatment of Eucalyptus grandis by Ceriporiopsis subvermispora affect a subsequent high-yield kraft pulping process. Under the varied culture conditions investigated, different extracellular enzyme activities were observed.…
The enzymes involved in the catabolism of leucine are encoded by the liu gene cluster in Pseudomonas aeruginosa PAO1. A mutant in the liuE gene (ORF PA2011) of P. aeruginosa was unable to utilize both leucine/isovalerate and acyclic terpenes as the carbon source. The liuE mutant grown in culture medium with citronello…
We report on a Si(3)N(4)-based surface-passivation technique for increasing free-carrier lifetimes in submicrometer silicon-on-insulator waveguides by up to 2 orders of magnitude. The carrier lifetime was measured by injecting free carriers into a critically coupled ring resonator through photoexcitation by short pump…
Cavitein Q4 is a template assembled synthetic protein designed for X-ray crystallographic analysis. It is based on a previous monomeric helical bundle cavitein (N1GG) that consists of four identical parallel helical peptides. Crystals that were grown in the presence of bromide ions were used to solve the initial phase…
The growth of thiophene/phenylene cooligomers is investigated on the basal surface of muscovite mica. Both the phenyl end-capped 5,5′-di-4-biphenylyl-2,2′-bithiophene (PPTTPP) and the thienyl end-capped 4,4′-di-2,2′-bithienylbiphenyl (TTPPTT) co-oligomers form fiberlike nanostructures from molecules lying on the subst…
Is it possible to increase ${T}_{c}$ by constructing cuprate heterostructures, which combine the high pairing energy of underdoped layers with the large carrier density of proximate overdoped layers? We investigate this question within a model bilayer system using an effective theory of the doped Mott insulator. Inter…
In this paper, we report on experimental and theoretical investigations of magnetic transitions in cobalt rings of size (diameter, width and thickness) comparable to the exchange length of cobalt. Magnetization measurements and calculations were performed for two sets of magnetic ring arrays: ultra-small magnetic ring…
Abstract Eucalyptus wood chips were impregnated with various blends of fiber modifying enzymes prior to preconditioning refiner chemical-alkaline peroxide mechanical pulp processing. The process includes chemical pretreatment and two stages of refining. The energy consumption was compared at the same Canadian standard…
In this study, chloridized mesoporous activated carbons (ClMAC) were prepared from used tyres. Their pore structure, surface chemistry and adsorptive capacities of toluene were investigated with nitrogen gas adsorption, Fourier transform infrared spectroscopy (FT-IR) and bench adsorptive experiments. A series of activ…
Transverse-field muon spin rotation $(\text{TF-}\ensuremath{\mu}\text{SR})$ experiments in the heavy-fermion superconductor ${\text{PrOs}}_{4}{\text{Sb}}_{12}({T}_{c}=1.85\text{ }\text{K})$ suggest that the superconducting penetration depth $\ensuremath{\lambda}(T)$ is temperature independent at low temperatures, cons…
The self-organization of a tokamak plasma is a fundamental turbulent plasma phenomenon, which leads to the formation of a self-consistent pressure profile. This phenomenon has been investigated in several tokamaks with different methods of heating. It is shown that the normalized pressure profile has a universal shape…
BACKGROUND: Invasive growth of epithelial cancers is a complex multi-step process which involves dissolution of the basement membrane. Type IV collagen is a major component in most basement membranes. Type VII collagen is related to anchoring fibrils and is found primarily in the basement membrane zone of stratified e…
Spin-noise appeal: Detection of NMR spin-noise is very appealing when dilute hyperpolarized species are considered. Continuous monitoring of the noise absorption at the Larmor frequency enables determination of T(1) and T(2)*, independently of the static magnetic field. An inductively coupled microcoil located inside…
Abstract Seitlich angedockt: In dem Mangan(III)‐Komplex 1 mit einem 13‐gliedrigen makrocyclischen Liganden ist ein Peroxoligand durch Side‐on‐η2‐Koordination gebunden. Die Reaktivität von 1 wird durch Einführung anionischer Liganden in trans‐Stellung zur Peroxogruppe beeinflusst. Elektronische und strukturelle Änderun…
We study the critical charge dynamics of the superconducting to the normal-state transition for ${\text{La}}_{2\ensuremath{-}x}{\text{Sr}}_{x}{\text{CuO}}_{4}$ (LSCO) thin films with a wide range of the Sr concentration by measuring the frequency-dependent excess parts of the complex microwave conductivity, which is i…
9(10),16-Dihydroxypalmitic acid (diHPA) is a particularly interesting polyhydroxylated fatty acid (1) because it is the main monomer of cutin, the most abundant biopolyester in nature, and (2) because the presence of a terminal and a secondary hydroxyl group in midchain positions provides an excellent model to study t…
We previously proposed a model of surfactant protein (SP)-C biosynthesis in which internalization of the proprotein from the limiting membrane of the multivesicular body to internal vesicles represents a key step in the processing and secretion of SP-C. To test this hypothesis, alanine mutagenesis of the N-terminal pr…
Abstract A centrosymmetric binuclear [{Cu(PPh3)2}2(piperzdtc)] (1) [piperzdtc2– = piperazinebis(dithiocarbamate)] and another mononuclear [{Cu(PPh3)2}(BzMedtc)] (2) (BzMedtc– = N‐benzyl‐N‐methyldithiocarbamate) complex have been synthesized and characterized by elemental analyses, IR, 1H, 13C, and 31P NMR spectroscopy…
A method for the analysis of time-resolved x-ray absorption near edge structure (XANES) spectra is proposed. It combines principal component analysis of the series of experimental spectra, multidimensional interpolation of theoretical XANES as a function of structural parameters, and ab initio XANES calculations. It a…
