description: Ο σκοπός της παρούσας εργασίας είναι ο υπολογισμός των δομικών, ηλεκτρονικών, θερμικών και θερμοηλεκτρικών ιδιοτήτων του νιτριδίου του ινδίου με δομή βουρτσίτη αποκλειστικά από πρώτες αρχές. Οι υπολογισμοί αυτοί βασίζονται στη Θεωρία Συναρτησιοειδών Πυκνότητας, η οποία είναι μια από τις πιο ακριβείς υπολογιστικές μεθόδους για προσομοιώσεις υλικών. Ειδικά για ιδιότητες που σχετίζονται φωνόνια και μεταφορά ηλεκτρονίων, οι υπολογισμοί από πρώτες αρχές έχουν γίνει δημοφιλής πρόσφατα, με την ανάπτυξη νέων αποτελεσματικών αλγορίθμων. Το υλικό που επιλέχθηκε ήταν το νιτρίδιο του ινδίου (InN), καθώς αποτελεί έναν πολλά υποσχόμενα αγωγό στην κατηγορία των νιτριδίων της ομάδας ΙΙΙ του περιοδικού πίνακα με πολλαπλές εφαρμογές σε φωτοβολταϊκά και οπτοηλεκτρονικές συσκευές, ειδικά σε κράματα με το νιτρίδιο του γαλλίου (GaN). Τα αποτελέσματα αυτής της εργασίας αποσκοπούν στο να δημιουργήσουν μια σφαιρική εικόνα των ιδιοτήτων του InN για τη βέλτιστη χρήση του σε εφαρμογές όπως οι προαναφερθείσες.
description: The aim of this study is the calculation of structural, electronic, thermal and thermoelectric properties of wurtzite InN solely from first principles. The backbone of these calculations is Density Functional Theory, which is one of the most accurate computational methods for materials simulations. Especially for phonon and electron transport related properties, calculations from first principles have become popular only recently, by the development of new efficient algorithms. The material of choice, InN, is a highly promising III-nitride semiconductor with multiple applications on solar cells and optoelectronic devices, especially when alloyed with GaN. Results of this study aim to provide a spherical image of the properties of InN for its optimal use in such applications.

description: Geometric phases are an interesting resource for quantum computation, also in view of their robustness against decoherence effects. We study here the effects of the environment on a class of one-qubit holonomic gates that have been recently shown to be characterized by "optimal" working times. We numerically analyze the behavior of these optimal points and focus on their robustness against noise.

Viscous vortex layers subject to more general strain and comparison to isotropic turbulence

Year: 2021
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: Viscous vortex layers subject to a more general uniform strain are considered. They include Townsend's steady solution for plane strain (corresponding to a parameter $a = 1$) in which all the strain in the plane of the layer goes toward vorticity stretching, as well as Migdal's recent steady asymmetric solution for axisymmetric strain ($a = 1/2$) in which half of the strain goes into vorticity stretching. In addition to considering asymmetric, symmetric and antisymmetric steady solutions $\forall a \ge 0$, it is shown that for $a < 1$, i.e., anything less than the Townsend case, the vorticity inherently decays in time: only boundary conditions that maintain a supply of vorticity at one or both ends lead to a non-zero steady state. For the super-Townsend case $a > 1$, steady states have a sheath of opposite sign vorticity. Comparison is made with homogeneous-isotropic turbulence in which case the average vorticity in the strain eigenframe is layer-like, has wings of opposite vorticity, and the strain configuration is found to be super-Townsend. Only zero-integral perturbations of the $a > 1$ steady solutions are stable; otherwise, the solution grows. Finally, the appendix shows that the average flow in the strain eigenframe is (apart from an extra term) the Reynolds-averaged Navier-Stokes equation.

description: (Abridged) Using a 100 ks XMM-Newton exposure of NGC 4051, we show that the time evolution of the ionization state of the X-ray absorbers in response to the rapid and highly variable X-ray continuum constrains all the main physical and geometrical properties of an AGN Warm Absorber wind. The absorber consists of two different ionization components. By tracking the response in the opacity of the gas in each component to changes in the ionizing continuum, we were able to constrain the electron density of the system. The measured densities require that the high and low ionization absorbing components of NGC 4051 must be compact, at distances 0.5-1.0 l-d (2200 - 4400Rs) and < 3.5 l-d (< 15800Rs) from the continuum source, respectively. This rules out an origin in the dusty obscuring torus, as the dust sublimation radius is at least an order of magnitude larger (>12 l-d). An accretion disk origin for the warm absorber wind is strongly suggested, and an association with the high ionization, HeII emitting, broad emission line region (radius <2 l-d) is possible. The two detected phases are consistent with pressure equilibrium, which suggests that the absorber consists of a two phase medium. A radial flow in a spherical geometry is unlikely, and a conical wind geometry is preferred. The implied mass outflow rate from this wind, can be well constrained, and is 2-5% of the mass accretion rate. If the mass outflow rate scaling with accretion rate is representative of all quasars, our results imply that warm absorbers in powerful quasars are unlikely to produce important evolutionary effects on their larger environment, unless we are observing the winds before they get fully accelerated. Only in such a scenario can AGN winds be important for cosmic feedback.

description: Consciência fonológica são habilidades que possibilitam a identificação e manipulação dos segmentos sonoros de um idioma, fundamental à alfabetização. Esse estudo objetivou identificar concepções, conhecimento teórico e práticas de ensino da consciência fonológica de professores dos anos iniciais do Ensino Fundamental. A pesquisa foi realizada entre agosto e dezembro de 2021, com 461 docentes da rede pública do Estado do Mato Grosso. Eles responderam uma escala contendo 14 frases para a autoavaliação. Foi realizada uma análise descritiva dos dados. Os resultados demonstraram que, em geral, os professores concordam que a estimulação da consciência fonológica é essencial às crianças. No entanto, há ausência de clareza total sobre o tema e carência de conhecimentos para avaliação e estimulação em sala de aula. Conclui-se que é importante investigar se essa realidade poderia ser modificada ao apresentar esse tema com maior ênfase desde a formação inicial do professor, dada sua relevância.

description: We introduce Neural Marching Cubes (NMC), a data-driven approach for extracting a triangle mesh from a discretized implicit field. Classical MC is defined by coarse tessellation templates isolated to individual cubes. While more refined tessellations have been proposed, they all make heuristic assumptions, such as trilinearity, when determining the vertex positions and local mesh topologies in each cube. In principle, none of these approaches can reconstruct geometric features that reveal coherence or dependencies between nearby cubes (e.g., a sharp edge), as such information is unaccounted for, resulting in poor estimates of the true underlying implicit field. To tackle these challenges, we re-cast MC from a deep learning perspective, by designing tessellation templates more apt at preserving geometric features, and learning the vertex positions and mesh topologies from training meshes, to account for contextual information from nearby cubes. We develop a compact per-cube parameterization to represent the output triangle mesh, while being compatible with neural processing, so that a simple 3D convolutional network can be employed for the training. We show that all topological cases in each cube that are applicable to our design can be easily derived using our representation, and the resulting tessellations can also be obtained naturally and efficiently by following a few design guidelines. In addition, our network learns local features with limited receptive fields, hence it generalizes well to new shapes and new datasets. We evaluate our neural MC approach by quantitative and qualitative comparisons to all well-known MC variants. In particular, we demonstrate the ability of our network to recover sharp features such as edges and corners, a long-standing issue of MC and its variants. Our network also reconstructs local mesh topologies more accurately than previous approaches.

description: We point out that fractionalized bosonic charge excitations can explain the recently discovered photo-induced superconducting-like response in $κ\text{-(ET})_2\text{Cu}[\text{N(CN)}_2]\text{Br}$, an organic metal close to the Mott transition. The pump laser exerts a periodic drive on the fractionalized field, creating a non-equilibrium condensate, which gives a Drude peak much narrower than the equilibrium scattering rate, hence superconducting-like response. Our proposal illuminates new possibilities of detecting fractionalization and can be readily tested in spin liquid candidates and in cold atom systems.

description: We present a study of molecular outflows using high-resolution mapping of the CO (1-0) line emission toward eight relatively nearby 6.7 GHz methanol masers, which are associated with massive star forming regions. Outflows were detected in seven out of eight sources, and five of them clearly show bipolar or multiple outflow morphologies. These outflows have typical masses of a few solar masses, momenta of tens of $M_{\odot}$ km s$^{-1}$, kinetic energies of $\sim$ 10$^{45}$ ergs, and the mass entrainment rate of a few $10^{-5} M_{\odot}$ yr$^{-1}$. They have significantly more mass and kinetic energy than their low-mass counterparts. In some of the sources, the massive outflow is obviously associated with a particular massive star in the cluster, while in others the origin remains uncertain. The high detection rate of outflows toward methanol masers suggests that the outflow phase of massive protostars encompasses the methanol maser phase.

description: The generation of high-intensity optical fields from harmonic-wave photons, interacting via a cross-phase modulation with dark solitons both propagating in a Kerr nonlinear medium, is examined. The focus is on a pump consisting of time-entangled dark-soliton patterns, forming a periodic waveguide along the path of the harmonic-wave probe. It is shown that an increase of the strength of cross-phase modulation respective to the self-phase modulation, favors soliton-mode proliferation in the bound-state spectrum of the trapped harmonic-wave probe. The induced soliton modes, which display the structures of periodic soliton lattices, are not just rich in numbers, they also form a great diversity of population of soliton crystals with a high degree of degeneracy.

description: We review several of the normal state properties of the cuprates in an attempt to establish an organizing principle from which pseudogap phenomena, broad spectral features, $T-$linear resistivity, and spectral weight transfer emerge. We first show that standard field theories with a single critical length scale cannot capture the $T-$linear resistivity as long as the charge carriers are critical. What seems to be missing is an additional length scale, which may or may not be critical. Second, we prove a generalised version of Luttinger's theorem for a Mott insulator. Namely, regardless of the spatial dimension, the Fermi surface of the non-interacting system is converted into a surface of zeros of the single-particle Green function when the Mott insulator posesses particle-hole symmetry. Only in the presence of particle-hole symmetry does the volume of the surface of zeros equal the particle density. The surface of zeros persists at finite doping and is shown to provide a framework from which pseudogaps, broad spectral features, spectral weight transfer on the Mott gap scale can be understood.

description: The main purpose of this work was to implement a special intervention program with teaching of learning strategies to Greek Pontian pupils at risk for learning disabilities. The intervention program was applied to a sample of 5 children, selected from a population of 31 pupils attending grades 3 and 4 in schools in the city of Alexandroupolis, Evros. The pupils were assessed using the Learning Disabilities Diagnostic Inventory, the Λ-α-Τ-ω (Lato) Language Acquisition Competence Test, Level II, and two achievement tests as data collection tools to detect those at risk for learning disabilities. Besides, following the implementation of the program, performance of children was reevaluated using again achievement tests. In order to analyze the results, the qualitative method was selected and the children's narratives were evaluated based on the theoretical model of Applebee's narrative form (1978). The conclusions from the program's implementation allow us to contend that children using the strategies were able to understand the main idea and details of a text and to produce organized stories based on robust structure.

Modern education in postmodern times: British Columbia’s community colleges at the fin de millennium
Creators: name: Falk, Cliff
Publisher: name: University of British Columbia
Year: 2009

description: The sureness of the modern educational project has been undermined by shifting epistemological and material conditions. The shift from modernity to postmodernity develops its own incongruencies and anomalies as well as highlighting those extant during modernity. Institutions like British Columbia's community colleges cling to the artifacts of modernity, leaving postmodern environments and discourse unacknowledged. This study applies rhetorical strategies, devices and the methodologies of literature and poststructural social studies, including the use of deliberate ambiguity and unstable signification, to write in opposition to the plain prose privileged by the technical instrumentality of mainstream adult education discourse in the North American academy. This de-centring of traditional academic discourse reframes and challenges prevailing constructions of Canada, education in Canada and community colleges in British Columbia. Exhuming and exposing some of the operational myths of modernity as they found expression in Canada through academic discourse and quotidian practice while offering an alternate story is the means by which my narrative proceeds. This re-storying, in turn, is used as a strategy to challenge modern mainstream educational and educational administrative practice, while attempting to normalize ways of seeing community colleges in British Columbia based outside of modernist orthodoxies.

description: A double new class of solutions to the general relativity field equations describing interior spacetimes sourced by stationary cylindrical anisotropic fluids with principal stress directed along the symmetry axis is displayed. These solutions are required to satisfy regularity and junction conditions so that they can be possibly used to represent rotating astrophysical objects. Mathematical and physical properties are analyzed. The spacetime two independent parameters are physically interpreted, and they are shown to define two different solution classes together with stating the latters' properties.

description: In the underdoped high temperature superconductors, instead of a complete Fermi surface above Tc, only disconnected Fermi arcs appear, separated by regions that still exhibit an energy gap. We show that in this pseudogap phase, the energy-momentum relation of electronic excitations near E_F behaves like the dispersion of a normal metal on the Fermi arcs, but like that of a superconductor in the gapped regions. We argue that this dichotomy in the dispersion is hard to reconcile with a competing order parameter, but is consistent with pairing without condensation.
Underscreening and hidden ion structures in large scale simulations of concentrated electrolytes

description: The electrostatic screening length predicted by Debye-Hückel theory decreases with increasing ionic strength, but recent experiments have found that the screening length can instead increase in concentrated electrolytes. This phenomenon, referred to as underscreening, is believed to result from ion-ion correlations and short-range forces such as excluded volume interactions among ions. We use Brownian Dynamics to simulate a version of the Restrictive Primitive Model for electrolytes over a wide range of ion concentrations, ionic strengths, and ion excluded volume radii for binary electrolytes. We measure the decay of the charge-charge correlation among ions in the bulk, and compare it against scaling trends found experimentally and determined in certain weak coupling theories of ion-ion correlation. Moreover, we find that additional large scale ion structures emerge at high concentrations. In this regime, the frequency of oscillations computed from the charge-charge correlation function is not dominated by electrostatic interactions but rather by excluded volume interactions and with oscillation periods on the order of the ion diameter. We also find that the nearest neighbor correlation of ions sharing the same charge transitions from negative at small concentrations to positive at high concentrations, representing the formation of small, like-charge ion clusters. We conclude that the increase in local charge density due to the formation of these clusters and the topological constraints of macroscopic charged surfaces can help explain the degree of underscreening observed experimentally.

description: Voltage-dependent ion channels determine the electric properties of axonal cell membranes. They not only allow the passage of ions through the cell membrane but also contribute to an additional charging of the cell membrane resulting in the so-called capacitance loading. The switching of the channel gates between an open and a closed configuration is intrinsically related to the movement of gating charge within the cell membrane. At the beginning of an action potential the transient gating current is opposite to the direction of the current of sodium ions through the membrane. Therefore, the excitability is expected to become reduced due to the influence of a gating current. Our stochastic Hodgkin-Huxley like modeling takes into account both the channel noise -- i.e. the fluctuations of the number of open ion channels -- and the capacitance fluctuations that result from the dynamics of the gating charge. We investigate the spiking dynamics of membrane patches of variable size and analyze the statistics of the spontaneous spiking. As a main result, we find that the gating currents yield a drastic reduction of the spontaneous spiking rate for sufficiently large ion channel clusters. Consequently, this demonstrates a prominent mechanism for channel noise reduction.

description: Background: Contraception is a technique to prevent a conception; its usage is a central element of quality care in the provision of family planning services and an important dimension of women’s reproductive rights. Barriers to use contraceptive is the factor that increase the likely hood of adverse mothers’ sexual and reproductive health consequence such as unwanted pregnancy or poorly timed pregnancy, unsafe abortion, maternal death and others. The objective of this study was to determine the barriers of contraceptive use among child bearing women living in Ambo town, West Shewa zone, Oromia Regional state, Ethiopia. Methodology: The study was conducted in Ambo town from February to March, 2015 G.C. Cross sectional study design was used& Participants were selected using systematic random sampling method. Data was collected by using structured questionnaires through face to face interviews & coded, entered and analyzed using EPI- INFO Version 3.5.1. The analyzed data was presented by using tables and graphs. Result: Forty percent of the respondents were using at least one contraceptive methods; injectable (58.8%) was the most used ones. Fear of side effect (25.8%) and desire to have a children were the most mentioned barrier for non-use. Multiple logistic regression model revealed that Educational status of mother (AOR 7.3, 95% CI: 3.22-16.6), and husband educational status (AOR 4.9, 95% CI: 1.4-16.9), religious influence (AOR 9.15, 95% CI: 1.75-46.9) and marital status (AOR: 1.95, 95% CI: 1.12-3.42) were positively associated with the use of contraceptives. Conclusion and recommendation: Contraceptive use rate was low. Therefore, the community should be encouraged to continue and use contraceptive so as to space family size and also leaders of religions to be involved in the education of the community to use contraceptive.

description: The performance of a small prototype of a cylindrical drift chamber (CDC) used in the COMET Phase-I experiment was studied by using an electron beam. The prototype chamber was constructed with alternating all-stereo wire configuration and operated with the He-iC$_{4}$H$_{10}$ (90/10) gas mixture without a magnetic field. The drift space-time relation, drift velocity, d$E$/d$x$ resolution, hit efficiency, and spatial resolution as a function of distance from the wire were investigated. The average spatial resolution of 150 $μ$m with the hit efficiency of 99% was obtained at applied voltages higher than 1800 V. We have demonstrated that the design and gas mixture of the prototype match the operation of the COMET CDC.

description: We quantify the scaling of magnetic energy density in the inertial range of solar wind turbulence seen in-situ at 1AU with respect to solar activity. At solar maximum, when the coronal magnetic field is dynamic and topologically complex, we find self-similar scaling in the solar wind, whereas at solar mimimum, when the coronal fields are more ordered, we find multifractality. This quantifies the solar wind signature that is of direct coronal origin, and distinguishes it from that of local MHD turbulence, with quantitative implications for our understanding of coronal heating of the solar wind.

Barrow Entropy Corrections to Friedmann Equations

description: Inspired by the Covid-$19$ virus structure, Barrow argued that quantum-gravitational effects may introduce intricate, fractal features on the black hole horizon [Phys. Lett. B {\bf808} (2020) 135643]. In this viewpoint, black hole entropy no longer obeys the area law and instead it can be given by $S\sim A^{1+δ/2}$, where the exponent $δ$ ranges $0\leqδ\leq1$, and indicates the amount of the quantum-gravitational deformation effects. Based on this, and using the deep connection between gravity and thermodynamics, we disclose the effects of the Barrow entropy on the cosmological equations. For this purpose, we start from the first law of thermodynamics, $dE=TdS+WdV$, on the apparent horizon of the Friedmann-Robertson-Walker (FRW) Universe, and derive the corresponding modified Friedmann equations by assuming the entropy associated with the apparent horizon has the form of Barrow entropy. We also examine the validity of the generalized second law of thermodynamics for the Universe enclosed by the apparent horizon. Finally, we employ the emergence scenario of gravity and extract the modified Friedmann equation in the presence of Barrow entropy which coincide with one obtained from the first law of thermodynamics. When $δ=0$, the results of standard cosmology are deduced.

description: This study is conducted to assess the fresh graduate of psychology students’ job expectation and preference in relation to the existing high unemployment rate. A simple qualitative research method with a cross sectional research design is employed in order to collect detailed and comprehensive information from the participants. The total number of population for this study is all 87 psychology 3 rd year students. Using academic achievement, place of residence and sex as an inclusion criterion, 32 participants (of which 16 were female and the rest 16 were male) were purposefully selected. To collect the desired information, semi-structured interview and Focus Group Discussion (FGD) were employed. The result of the study revealed that, majority of psychology fresh graduates expect and prefer to be employed in their field of specialization. It is also found that, fresh psychology graduates’ job expectation and preference are affected by their sex, in which female fresh graduates are found to have low expectation and preference. It was also found that, academic achievement and residence have affected fresh psychology graduates’ job expectation and preference. Majority of fresh psychology graduates with high academic achievement expect and prefer to be employed in their field of specialization with the highest salary, unlike those with relatively lower academic achievement. With some exceptions due to sex and academic achievement, majority of psychology fresh graduates’ job expectation and preference are affected by their residence. That is, fresh psychology graduates from rural area are found to have less expectation and preference of being employed in their field of specialization.

description: Traditional cutoff regularization schemes of the Nambu--Jona-Lasinio model limit the applicability of the model to energy-momentum scales much below the value of the regularizing cutoff. In particular, the model cannot be used to study quark matter with Fermi momenta larger than the cutoff. In the present work an extension of the model to high temperatures and densities recently proposed by Casalbuoni, Gatto, Nardulli, and Ruggieri is used in connection with an implicit regularization scheme. This is done by making use of scaling relations of the divergent one-loop integrals that relate these integrals at different energy-momentum scales. Fixing the pion decay constant at the chiral symmetry breaking scale in the vacuum, the scaling relations predict a running coupling constant that decreases as the regularization scale increases, implementing in a schematic way the property of asymptotic freedom of quantum chromodynamics. If the regularization scale is allowed to increase with density and temperature, the coupling will decrease with density and temperature, extending in this way the applicability of the model to high densities and temperatures. These results are obtained without specifying an explicit regularization. As an illustration of the formalism, numerical results are obtained for the finite density and finite temperature quark condensate, and to the problem of color superconductivity at high quark densities and finite temperature.

description: We present a search for gravitational waves from the coalescence of sub-solar mass black hole binaries using data from the first half of Advanced LIGO and Virgo's third observing run. The observation of a sub-solar mass black hole merger may be an indication of primordial origin; primordial black holes may contribute to the dark matter distribution. We search for black hole mergers where the primary mass is $0.1-7 M_{\odot}$ and the secondary mass is $0.1-1 M_{\odot}$. A variety of models predict the production and coalescence of binaries containing primordial black holes; some involve dynamical assembly which may allow for residual eccentricity to be observed. For component masses $>0.5 M_{\odot}$, we also search for sources in eccentric orbits, measured at a reference gravitational-wave frequency of 10 Hz, up to $e_{10}\sim 0.3$. We find no convincing candidates and place new upper limits on the rate of primordial black hole mergers. The merger rate of 0.5-0.5 (1.0-1.0)~$M_{\odot}$ sources is $<7100~(1200)$ Gpc$^{-3}$yr$^{-1}$. Our limits are $\sim3-4$ times more constraining than prior analyses. Finally, we demonstrate how our limits can be used to constrain arbitrary models of the primordial black hole mass distribution and merger rate.

description: Suzaku has, for the first time, enabled the hard X-ray variability of the Seyfert 1 galaxy MCG-6-30-15 to be measured. The variability in the 14-45 keV band, which is dominated by a strong reflection hump, is quenched relative to that at a few keV. This directly demonstrates that the whole reflection spectrum is much less variable than the power-law continuum. The broadband spectral variability can be decomposed into two components - a highly variable power-law and constant reflection - as previously inferred from other observations in the 2-10 keV band. The strong reflection and high iron abundance give rise to a strong broad iron line, which requires the inner disc radius to be at about 2 gravitational radii. Our results are consistent with the predictions of the light bending model which invokes the very strong gravitational effects expected very close to a rapidly spinning black hole.
