Exchange-constants have been evaluated from first-principles in Mn-doped Ge, mainly focusing on the effects of the impurity concentration and of the arrangement of Mn-atoms in the semiconducting matrix. As expected, the Mn-concentration strongly affects the magnitude of the exchange constants (especially between Mn as first-nearest-neighbors (NNs) in the cation position). Interestingly, the arr...

Al-Mg-Ge alloys are considered to exhibit similar aging behavior as Al-Mg-Si alloys, therefore, they have been alternatively used analyze precipitates in alloys. However, the interactions between solute atoms and vacancies not clear. In this study, binding energies were investigated using first-principles calculations, similarities differences of biding energy each alloy analyzed. Comparing thr...

It is demonstrated that the Sutherland Hamiltonian is equivalent to particles interacting with the vector statistical interaction on the rim of a circle, to within a nonsingular gauge transformation. PACS numbers: 05.45.+b, 03.65.Ge

Identification of the genetic architecture of phenotypic stability and management of adaptational genes is a prerequisite for improvement of adaptation. To locate the genes controlling adaptation, disomic addition lines of agropyron (agropyron elongatum, 2n=2x=14) into the genetic background of bread wheat (Triticum aestivum L., 2n=6x=42, cv. ‘Chinese Spring’=CS) were used in a randomized compl...

DESPEC is one of the experiments of the low-energy branch project of the future installations at FAIR (GSI). The main goal of this experiment is to study the decay properties of exotic nuclei. The basic instrumentation of this setup includes a set of implantation detectors, a Ge array and neutron detectors. Presently the collaboration is considering two possible setups for the Ge array. One pos...

Two 2 × 2 factorial experiments were conducted to investigate the interaction between xylanase (0 vs. 200 mg/kg) and protease (0 vs. 200 mg/kg) enzyme supplementation on growth performance (Exp. 1) and coefficient of ileal and total tract apparent digestibility in grower-finisher pigs (Exp. 2). One hundred and twenty-eight individual fed pigs (BW = 34.2 kg; n = 32) were assigned to 1 of 4 dieta...

There are many cases where the interaction between two qubits is not precisely known, but single-qubit operations are available. In this Letter we show how, regardless of an incomplete knowledge of the strength or form of the interaction between two qubits, it is often possible to construct a controlled-NOT gate which has arbitrarily high fidelity. In particular, we show that oscillations in th...

The germanium nitride and InP nanowires were grown using the pyrolytic decomposition products of hydrazine (N2H4), which was containing 3 mol.% H2O. In a separate set of experiments the quartz microbalance was used to study the interaction of water containing hydrazine with Ge sample in the temperature range of 450-650°C. It was established that up to 500°C only water molecules interact with Ge...

The potential of thio and seleno germanones [LPhGe═E] (L = aminotroponiminate (ATI) ligand, E = S 3, Se 4) to function as ligands has been demonstrated through the isolation of their silver(I) iodide complexes [{(t-Bu)2ATIGe(E)Ph}2(Ag2I2)] (E = S 5, Se 6) with a planar and discrete Ag2I2 core. Compounds 5 and 6 possess the hitherto unknown Ge═E→Ag-I moieties and the crystallographic data reveal...
