description: We investigate the spatial distribution of temperature induced by a dc current in a two-dimensional electron gas (2DEG) subjected to a perpendicular magnetic field. We numerically calculate the distributions of the electrostatic potential phi and the temperature T in a 2DEG enclosed in a square area surrounded by insulated-adiabatic (top and bottom) and isopotential-isothermal (left and right) boundaries (with phi_{left} < phi_{right} and T_{left} =T_{right}), using a pair of nonlinear Poisson equations (for phi and T) that fully take into account thermoelectric and thermomagnetic phenomena, including the Hall, Nernst, Ettingshausen, and Righi-Leduc effects. We find that, in the vicinity of the left-bottom corner, the temperature becomes lower than the fixed boundary temperature, contrary to the naive expectation that the temperature is raised by the prevalent Joule heating effect. The cooling is attributed to the Ettingshausen effect at the bottom adiabatic boundary, which pumps up the heat away from the bottom boundary. In order to keep the adiabatic condition, downward temperature gradient, hence the cooled area, is developed near the boundary, with the resulting thermal diffusion compensating the upward heat current due to the Ettingshausen effect.

description: In this paper we address the problem of translating one-way quantum computation (1WQC) into the circuit model. We start by giving a straightforward circuit representation of any 1WQC, at the cost of introducing many ancilla wires. We then propose a set of four simple circuit identities that explore the relationship between the entanglement resource and correction structure of a 1WQC, allowing one to obtain equivalent circuits acting on fewer qubits. We conclude with some examples and a discussion of open problems.

Retention in Phonetics and Phonology

description: The goal of this study was to ascertain how objective-based strategies affected senior secondary school students in Enugu Education Zone of Enugu State, Nigeria, in terms of their success and retention in phonetics and phonology. To direct the investigation, two null hypotheses and two research questions were developed. Conceptual and theoretical frameworks, empirical research, and summaries of linked literature were all examined as related literatures. A quasi-experimental design with a non-equivalent control group was used. The study's subject was a sample of 381 SSII students taken from three public secondary schools in the Enugu education zone.  In each of the schools, two complete classes were randomly assigned to the experimental group and the Control group. The researcher created, validated, and used the Phonetics and Phonology Achievement Test (PPAT) in the study. To determine the accuracy of the instruments, a trial test was conducted in a nearby zone.  The researcher created two distinct lesson plans, one for an objectives-based technique and the other for an explanatory strategy. The mean, standard deviation, and Analysis of Covariance (ANCOVA) were used to examine the study's data. The study's findings indicated that there is significant difference between the mean achievement scores of students taught phonetics and phonology with the objectives-based strategy (experimental) and those taught with expository approach (control). The findings have consequences for English language students, English language teachers, and the organizations that train English language teachers. The study suggested, among other things, that English language teachers be urged to constantly switch up their teaching and learning methods.

description: We have conducted a kinematic study of 165 young M dwarfs with ages of <300 Myr. Our sample is composed of stars and brown dwarfs with spectral types ranging from K7 to L0, detected by ROSAT and with photometric distances of <25 pc assuming the stars are single and on the main-sequence. In order to find stars kinematically linked to known young moving groups (YMGs), we measured radial velocities for the complete sample with Keck and CFHT optical spectroscopy and trigonometric parallaxes for 75 of the M dwarfs with the CAPSCam instrument on the du Pont 2.5-m Telescope. Due to their youthful overluminosity and unresolved binarity, the original photometric distances for our sample underestimated the distances by 70% on average, excluding two extremely young (<3 Myr) objects found to have distances beyond a few hundred parsecs. We searched for kinematic matches to 14 reported YMGs and identified 9 new members of the AB Dor YMG and 2 of the Ursa Majoris group. Additional possible candidates include 6 Castor, 4 Ursa Majoris, 2 AB Dor members, and 1 member each of the Her-Lyr and beta Pic groups. Our sample also contains 27 young low-mass stars and 4 brown dwarfs with ages <150 Myr which are not associated with any known YMG. We identified an additional 15 stars which are kinematic matches to one of the YMGs, but the ages from spectroscopic diagnostics and/or the positions on the sky do not match. These warn against grouping stars together based only on kinematics and that a confluence of evidence is required to claim that a group of stars originated from the same star-forming event.

description: Motivated by recent physical interpretation on quasinormal modes presented by Maggiore, the adiabatic quantity method given by Kunstatter is used to calculate the spectrums of a non-extremal Schwarzschild de Sitter black hole in this paper, as well as electrically charged case. According to highly damped Konoplya and Zhidenko's numerical observational results for high overtone modes\cite{Konoplya}, we found that the asymptotic non-flat spacetime structure leads two interesting facts as followings: (i) near inner event horizon, the area and entropy spectrums, which are given by $A_{en} = 8 n_1 π\hbar$, $S_{en} = 2πn_1\hbar$, are equally spaced accurately. (ii) However, near outer cosmological horizon the spectrums, which are in the form of $A_{cn} = 16 n_2 π\hbar - \sqrt{\frac{48π}ΛA_{cn} - 3 A_{cn}^2}$, $S_{cn} = 4 πn_2 \hbar - \sqrt{\frac{3π}ΛA_{cn} - 3/16 A_{cn}^2}$, are not markedly equidistant. Finally, we also discuss the electrically charged case and find the black holes in de Sitter spacetime have similar quantization behavior no matter with or without charge.

description: We propose a simple scheme that describes accurately essential non-equilibrium effects in nanoscale electronics devices using equilibrium transport theory. The scheme, which is based on the alignment and dealignment of the junction molecular orbitals with the shifted Fermi levels of the electrodes, simplifies drastically the calculation of current-voltage characteristics compared to typical non-equilibrium algorithms. We probe that the scheme captures a number of non-trivial transport phenomena such as the negative differential resistance and rectification effects. It applies to those atomic-scale junctions whose relevant states for transport are spatially placed on the contact atoms or near the electrodes.

description: For the past several years, a major effort has been undertaken at Los Alamos National Laboratory (LANL) to develop the transport code MCNP6, the latest LANL Monte-Carlo transport code representing a merger and improvement of MCNP5 and MCNPX. We emphasize a description of the latest developments of MCNP6 at higher energies to improve its reliability in calculating rare-isotope production, high-energy cumulative particle production, and a gamut of reactions important for space-radiation shielding, cosmic-ray propagation, and accelerator applications. We present several examples of validation and verification of MCNP6 compared to a wide variety of intermediate- and high-energy experimental data on reactions induced by photons, mesons, nucleons, and nuclei at energies from tens of MeV to about 1 TeV/nucleon, and compare to results from other modern simulation tools.

We show that if two orbits are freely homotopic then in fact they are isotopic. We show that lifts of periodic orbits to the universal cover are unknotted. When the manifold is atoroidal, we deduce some finer properties regarding the existence of embedded cylinders connecting two given homotopic orbits.

Finally, we present our predictions for antineutrino scattering.

description: Quasiparticle recombination in a superconductor with an s-wave gap is typically dominated by a phonon bottleneck effect. We have studied how a magnetic field changes this recombination process in metallic thin-film superconductors, finding that the quasiparticle recombination process is significantly slowed as the field increases. While we observe this for all field orientations, we focus here on the results for a field applied parallel to the thin film surface, minimizing the influence of vortices. The magnetic field disrupts the time-reversal symmetry of the pairs, giving them a finite lifetime and decreasing the energy gap. The field could also polarize the quasiparticle spins, producing different populations of spin-up and spin-down quasiparticles. Both processes favor slower recombination; in our materials we conclude that strong spin-orbit scattering reduces the spin polarization, leaving the field-induced gap reduction as the dominant effect and accounting quantitatively for the observed recombination rate reduction.

description: We solve the equivalence problem for vacuum PP-wave spacetimes by employing the Karlhede algorithm. Our main result is a suite of Cartan invariants that allows for the complete invariant classification of the vacuum pp-waves. In particular, we derive the invariant characterization of the G2 and G3 sub-classes in terms of these invariants. It is known [Collins91] that the invariant classification of vacuum pp-waves requires at most the fourth order covariant derivative of the curvature tensor, but no specific examples requiring the fourth order were known. Using our comprehensive classification, we prove that the q<=4 bound is sharp and explicitly describe all such maximal order solutions.

description: Cytochrome P450s (CYPs) are an essential family of enzymes in the human body. They play a crucial role in metabolism, especially in human steroid biosynthesis. Reactions catalyzed by these enzymes are highly stereo- and regio-specific. Lack or severe malfunctions of CYPs can cause severe diseases and even shorten life. Hence, investigations on metabolic reactions and structural requirements of substrates are crucial to gain further knowledge on the relevance of different enzymes in the human body functions and the origin of diseases. One key enzyme in the biosynthesis of gluco- and mineralocorticoids is CYP21A2, also known as steroid 21-hydroxylase. To investigate the steric and regional requirements of substrates for this enzyme, we performed whole-cell biotransformation assays using a strain of fission yeast Schizosaccharomyces pombe recombinantly expressing CYP21A2. The progestogens progesterone, pregnenolone, and their 17α-hydroxy-derivatives were used as substrates. After incubation, samples were analyzed using gas chromatography coupled to mass spectrometry. For progesterone and 17α-hydroxyprogesterone, their corresponding 21-hydroxylated metabolites 11-deoxycorticosterone and 11-deoxycortisol were detected, while after incubation of pregnenolone and 17α-hydroxypregnenolone, no hydroxylated product was observed. Findings were confirmed with authentic reference material. Molecular docking experiments agree with these results and suggest that interaction between the 3-oxo group and arginine-234 of the enzyme is a strict requirement. The presented results demonstrate once more that the presence of an oxo-group in position 3 of the steroid is indispensable, while a 3-hydroxy group prevents hydroxylation in position C-21 by CYP21A2. This knowledge may be transferred to other CYP21A2 substrates and hence help to gain essential insights into steroid metabolism.

The hard X-ray performance of pixelated CdTe-based detectors using Monte Carlo and ab initio simulations

description: The performance of pixelated semiconductor radiation detectors based on cadmium telluride (CdTe) were investigated using experimental, Monte Carlo and ab initio methods for their detection of hard X-rays while operating at room temperature. To achieve the imaging, photon-counting and energy-resolving requirements of CdTe-based detector applications, pixelated detector designs are commonly used. Charge sharing and fluorescence interference as a result of pixelation, and distortions of the electric field profile, severely impact the performance in these detectors. Inhomogeneities and defects in the crystals due to on-going growth challenges of CdTe also limit performance. The photon-counting and spectral performance of a novel high-flux capable CdZnTe (HFCdZnTe) is measured at photon energies 6 to 140 keV and compared with a gold-standard CdTe detector. Factors contributing to the energy resolution of charge sharing events such as charge loss and fluorescence are quantified. A fully spectroscopic Monte Carlo (MC) detector model is developed and shown to accurately predict the rate of charge sharing in these detectors. By comparing experimental and MC simulated data, a number of quantities related to performance such as the size of the electron charge clouds, the strength of the electric field and the Zn concentration in the HF-CdZnTe material are estimated. Using density functional theory (DFT), alloys of CdTe that are in early stages of development for radiation detection are studied from ab initio. The formation of the cadmium vacancy defect (VCd) in Cd1−xMnxTe and Cd1−xMgxTe crystals is studied and compared with the more well established Cd1−xZnxTe system. The VCd formation energy as a function of alloy concentration x is calculated to help understand the defect concentrations and resistivity in these alloys. The effect the addition of Mn and Mg have on the physical properties of CdTe, including phase transitions of their lattices, are also determined.

description: We construct a closed-form, fully analytical 4-metric that approximately represents the spacetime evolution of non-precessing, spinning black hole binaries from infinite separations up to a few orbits prior to merger. We employ the technique of asymptotic matching to join a perturbed Kerr metric in the neighborhood of each spinning black hole to a near-zone, post-Newtonian metric farther out. The latter is already naturally matched to a far-zone, post-Minkowskian metric that accounts for full temporal retardation. The result is a 4-metric that is approximately valid everywhere in space and in a small bundle of spatial hypersurfaces. We here restrict our attention to quasi- circular orbits, but the method is valid for any orbital motion or physical scenario, provided an overlapping region of validity or buffer zone exists. A simple extension of such a metric will allow for future studies of the accretion disk and jet dynamics around spinning back hole binaries.

description: This dissertation represents twelve months of ethnographic research conducted in Jaffna, Sri Lanka with a group of rickshaw drivers who work on the street leading to the Railway Station, Station Road. In trying to understand the lives of these men, this research has focused on developing a collection of narratives of everyday experiences as told by the drivers and observed by the researcher. These stories, and therefore this dissertation, center around the promises and paradoxes of mobility and masculinity in postwar Jaffna through an examination of ordinary realities such as playing games, the struggle to earn hires, vehicle ornamentation, and experiences of militarized policing. These narratives are told situationally in an effort to keep the analysis grounded in the mundane and unexceptional even as it incorporates the extraordinary insights and implications of feminist, queer of color, and postcolonial theoretical frames. In weaving together ethnographic narratives of everyday life with a varied assemblage of disciplinary and methodological sensibilities, this dissertation works to evoke and interpret the unacknowledged complexity of that which is seen but unremarked. Doing so, this dissertation argues, is important in light of, and not despite, the understandable urge to simplify narratives of unfamiliar and/or distant peoples, places, and cultures. Thus, while it important to interrogate the causes and contexts of war and terrorism, which are necessarily macro and global concerns, it remains vitally important to give attention to small stories playing out in small places, without which it becomes impossible to grasp the nuances of larger events. This dissertation is therefore only indirectly about the tragedies that are often the focus of scholarly attention. War, trauma, and violence serve as background, but rarely ever as subject, for the routine, ordinary lives of the men of Station Road. This dissertation takes masculinity and mobility to be dominant themes in these lives, examining them according to the premise that prolonged engagement and attention to their everyday struggles and joys yields something worthwhile, something less than extraordinary but more than ordinary.

description: We compare the observed probability distribution function of the transmission in the \HI\ Lyman-alpha forest, measured from the UVES 'Large Programme' sample at redshifts z=[2,2.5,3], to results from the GIMIC cosmological simulations. Our measured values for the mean transmission and its PDF are in good agreement with published results. Errors on statistics measured from high-resolution data are typically estimated using bootstrap or jack-knife resampling techniques after splitting the spectra into chunks. We demonstrate that these methods tend to underestimate the sample variance unless the chunk size is much larger than is commonly the case. We therefore estimate the sample variance from the simulations. We conclude that observed and simulated transmission statistics are in good agreement, in particular, we do not require the temperature-density relation to be 'inverted'.

description: As part of this thesis, a new strategy for the inversion of stress states from fault-slip data is introduced (Chapter 2). This new approach is applied to data sampled from outcrops along the southern margin of the CEBS (Chapter 4) and from outcrops in the Oslo Graben area (Chapter 5). The results derived from these study areas deliver new insights into the evolution of paleostress fields that controlled the development of the entire CEBS.

description: We study the existence of positive solutions on $\R^{N+1}$ to semilinear elliptic equation $-Δu+u=f(u)$ where $N\geq 1$ and $f$ is modeled on the power case $f(u)=|u|^{p-1}u$. Denoting with $c$ the mountain pass level of $\f(u)=\tfrac 12\|u\|^{2}_{H^{1}(\R^{N})}-\int_{\R^{N}}F(u)\, dx$, $u\in H^{1}(\R^{N})$ ($F(s)=\int_{0}^{s}f(t)\, dt$), we show, via a new energy constrained variational argument, that for any $b\in [0,c)$ there exists a positive bounded solution $v_{b}\in C^{2}(\R^{N+1})$ such that $E_{v_{b}}(y)=\tfrac 12\|\partial_{y}v_{b}(\cdot,y)\|^{2}_{L^{2}(\R^{N})}-V(v_{b}(\cdot,y))=-b$ and $v(x,y)\to 0$ as $|x|\to+\infty$ uniformly with respect to $y\in\R$. We also characterize the monotonicity, symmetry and periodicity properties of $v_{b}$.

description: Within the framework of ImQMD05, we study several isospin sensitive observables, such as DR(n/p) ratios, isospin transport ratio (isospin diffusion), yield ratios for LCPs between the projectile region and mid-rapidity region for the reaction systems Ni+Ni, Zn+Zn, Sn+Sn at low-intermediate energies. Our results show that those observables are sensitive to the density dependence of symmetry energy, and also depend on the cluster formation mechanism. By comparing these calculations to the data, the information of the symmetry energy and reaction mechanism is obtained.

description: We report systematic variations in the CO(2-1)/CO(1-0) line ratio (R) in M51. The ratio shows clear evidence for the evolution of molecular gas from the upstream interarm regions, passage into the spiral arms and back into the downstream interarm regions. In the interarm regions, R is typically low <0.7 (and often 0.4-0.6); this is similar to the ratios observed in Galactic giant molecular clouds (GMCs) with low far-IR luminosities. However, the ratio rises to >0.7 (often 0.8-1.0) in the spiral arms, particularly at their leading (downstream) edge. R is also high, 0.8-1.0, in the central region. An LVG calculation provides insight into the changes in the gas physical conditions between the arm and interarm regions: cold and low density gas (~10K, ~300cm-3) is required for the interarm GMCs, but this gas must become warmer and/or denser in the more active star forming spiral arms. R is higher in areas of high 24micron brightness (an approximate tracer of star formation rate surface density) and high CO(1-0) integrated intensity (a well-calibrated tracer of total molecular gas surface density). The systematic enhancement of the CO(2-1) line relative to CO(1-0) in luminous star forming regions suggests that some caution is needed when using CO(2-1) as a tracer of bulk molecular gas mass.

description: Quantification of relations between measured variables of interest by statistical measures of dependence is a common step in analysis of climate data. The term "connectivity" is used in the network context including the study of complex coupled dynamical systems. The choice of dependence measure is key for the results of the subsequent analysis and interpretation. The use of linear Pearson's correlation coefficient is widespread and convenient. On the other side, as the climate is widely acknowledged to be a nonlinear system, nonlinear connectivity quantification methods, such as those based on information-theoretical concepts, are increasingly used for this purpose. In this paper we outline an approach that enables well informed choice of connectivity method for a given type of data, improving the subsequent interpretation of the results. The presented multi-step approach includes statistical testing, quantification of the specific non-linear contribution to the interaction information, localization of nodes with strongest nonlinear contribution and assessment of the role of specific temporal patterns, including signal nonstationarities. In detail we study the consequences of the choice of a general nonlinear connectivity measure, namely mutual information, focusing on its relevance and potential alterations in the discovered dependence structure. We document the method by applying it on monthly mean temperature data from the NCEP/NCAR reanalysis dataset as well as the ERA dataset. We have been able to identify main sources of observed non-linearity in inter-node couplings. Detailed analysis suggested an important role of several sources of nonstationarity within the climate data. The quantitative role of genuine nonlinear coupling at this scale has proven to be almost negligible, providing quantitative support for the use of linear methods for this type of data.

description: This study examined the effect of monetary policy on price stabilization in Nigeria during the period 1981-2021. Data for the study were extracted from the Central Bank of Nigeria (CBN) statistical bulletin and world development index (WDI) 2021. The method of data analysis used is linear regression method with application of Error Correction Model (ECM). The major findings of the study reveal that liquidity ratio has negative and non-significant effect on price stabilization in Nigeria. Cash reserve ratio has a positive but non-significant effect on price stabilization in Nigeria. Monetary policy rate has a positive but non-significant effect on price stabilization in Nigeria. Finally, there exists no causal relationship amongst the variables under investigation. It is therefore the recommendation of the study that to maintain a relatively stable economy, monetary authorities should increase their liquid assets over liabilities so that it will be significant to stabilize price in the Nigerian economy. Secondly, that the Central Bank of Nigeria should modify their regulations to deposit money banks to make sure that they don't keep more than the required cash for creation of money. Thirdly, that the Central Bank of Nigeria needs to reduce monetary policy rate and enforce deposit money banks to charge different interest rates for borrowing purposes. This will relatively make monetary policy rate significant in the Nigerian economy. Finally, the study recommends that government needs to evaluate these monetary policy instruments so that they can be engaged optimally
On a multiscale strategy and its optimization for the simulation of combined delamination and buckling

description: This paper investigates a computational strategy for studying the interactions between multiple through-the-width delaminations and global or local buckling in composite laminates taking into account possible contact between the delaminated surfaces. In order to achieve an accurate prediction of the quasi-static response, a very refined discretization of the structure is required, leading to the resolution of very large and highly nonlinear numerical problems. In this paper, a nonlinear finite element formulation along with a parallel iterative scheme based on a multiscale domain decomposition are used for the computation of 3D mesoscale models. Previous works by the authors already dealt with the simulation of multiscale delamination assuming small perturbations. This paper presents the formulation used to include geometric nonlinearities into this existing multiscale framework and discusses the adaptations that need to be made to the iterative process in order to ensure the rapid convergence and the scalability of the method in the presence of buckling and delamination. These various adaptations are illustrated by simulations involving large numbers of DOFs.

description: The idea of embedding and transmitting information within the fluctuations of the magnetic moments of spins (spin waves) has been recently proposed and experimentally tested. The coherence of spin waves, which describes how well defined these excitations are, is of course vital to this process, and themost significant factor that affects the spin-wave coherence is temperature. Here we present neutron inelastic scattering measurements of the full threedimensional spin-wave dispersion in BiFeO3, which is one of the most promising functional multiferroic material, for temperatures from 5K to 700K. Despite the presence of strong electromagnetic coupling, the magnetic excitations behave like conventional magnons over all parts of the Brillouin zone. At low temperature the spin-waves are well-defined coherent modes, described by a classical model for a G-type antiferromagnet. A spin-wave velocity softening is already present at room temperature, and more pronounced damping occurs as the magnetic ordering temperature TN \sim 640K is approached. In addition, a strong hybridization of the Fe 3d and O 2p states is found to modify the distribution of the spin-wave spectral weight significantly, which implies that the spins are not restricted to the Fe atomic sites as previously believed.

description: Recent cosmological data favour additional relativistic degrees of freedom beyond the three active neutrinos and photons, often referred to as "dark radiation". Extensions of the SM involving TeV-scale Z' gauge bosons generically contain superweakly interacting light right-handed neutrinos which can constitute this dark radiation. In this letter we confront the requirement on the parameters of the E6 Z' models to account for the present evidence of dark radiation with the already existing constraints from searches for new neutral gauge bosons at LHC7.
