description: Technology has affected the development of the education process over time. COVID-19 pandemic has forced educational facilities to close. Consequently, transformation from face-to-face educational approach to the E-learning approach has pushed the world to enter a new state of learning. This situation has elicited doubts about the implementation and the difficulties related with this immediate action. In this paper, statistical analysis was used on the filled survey by the instructors and students at the Hashemite University (HU) to investigate the quality of the E-learning process. Various factors such as e-content, Virtual Classroom (VC) and Learning Management System (LMS), and Technology Infrastructure affect E-learning process. A contradiction between instructors’ and students’ opinions regarding the usage of the E-learning at HU exists. Therefore, a set of recommendations was made to overcome the shortage in the E-learning process and to reach a full satisfaction about the quality of its implementation in future.

Year: 2021

description: The pandemic emergency has almost forced the transition from face-to-face to remote evaluation. Starting from the results of the research in Mathematics Education, this exploratory work focuses on how to design effective closed-ended questions of different types, capable of reliably assessing mathematical learning outcomes, especially in terms of the involved competencies. We also investigate how to aggregate the questions into Moodle quizzes able to effectively replace the traditional open written exam. We propose a three-dimensional theoretical model, which takes into account the various types of questions, expected learning outcomes, and mathematical arguments, to shed light on the problems of validity, reliability, balance, and correctness of closed-ended quizzes. We discuss the results of the first implementation of the model within a Linear Algebra course for engineering freshmen.

Survival probability of a diffusing test particle in a system of coagulating and annihilating random walkers

description: We calculate the survival probability of a diffusing test particle in an environment of diffusing particles that undergo coagulation at rate lambda_c and annihilation at rate lambda_a. The test particle dies at rate lambda' on coming into contact with the other particles. The survival probability decays algebraically with time as t^{-theta}. The exponent theta in d<2 is calculated using the perturbative renormalization group formalism as an expansion in epsilon=2-d. It is shown to be universal, independent of lambda', and to depend only on delta, the ratio of the diffusion constant of test particles to that of the other particles, and on the ratio lambda_a/lambda_c. In two dimensions we calculate the logarithmic corrections to the power law decay of the survival probability. Surprisingly, the log corrections are non-universal. The one loop answer for theta in one dimension obtained by setting epsilon=1 is compared with existing exact solutions for special values of delta and lambda_a/lambda_c. The analytical results for the logarithmic corrections are verified by Monte Carlo simulations.

description: Richard (2017) found evidence revealing MPP impact differences due to milk and feed market differences across the dairy production regions. The Margin Protection Program is likely to be reformed in the 2018 Farm Bill in order to address producer’s concerns. There are many approaches to analyze potential new policies. This paper will document recent proposals and develop an additional approach to reforming the federal dairy safety net. The cases of New Mexico and Wisconsin will be examined for how a shift in the range of margins protected by MPP might affect risk reduction.

description: White dwarf stars are the most common end point of stellar evolution. Of special interest are the ultramassive white dwarfs, as they are related to type Ia Supernovae explosions, merger events, and Fast Radio Bursts. Ultramassive white dwarfs are expected to harbour oxygen-neon (ONe) cores as a result of single standard stellar evolution. However, a fraction of them could have carbon-oxygen (CO) cores. Recent studies, based on the new observations provided by the {\it Gaia} space mission, indicate that a small fraction of the ultramassive white dwarfs experience a strong delay in their cooling, which cannot be attributed only to the occurrence of crystallization, thus requiring an unknown energy source able to prolong their life for long periods of time. In this study we find that the energy released by $^{22}$Ne sedimentation in the deep interior of ultramassive white dwarfs with CO cores and high $^{22}$Ne content is consistent with the long cooling delay of these stellar remnants. On the basis of a synthesis study of the white dwarf population, based on Monte Carlo techniques, we find that the observations revealed by {\it Gaia} can be explained by the existence of these prolonged youth ultramassive white dwarfs. Although such a high $^{22}$Ne abundance is not consistent with the standard evolutionary channels, our results provide sustain to the existence of CO-core ultramassive white dwarfs and to the occurrence of $^{22}$Ne sedimentation.

description: This work analyzes the teaching and educational approach, based on Distance Learning, used in a Mathematics class with Engineering students. Thinking critically about how we worked before the COVID-19 crisis, we try to elaborate on possible ways to overcome linear processes' inertia. The teacher's educational activities and the students’ reactions are analyzed in the light of the theory of Transformative Learning. We adopt the theoretical and analytical tools provided by the theory of Interest Dense Situation and the theory of Self-Determination. A qualitative and quantitative analysis was conducted referring to a didactic experiment monitoring various elements through a questionnaire consisting of open-ended and Likert questions and thought closed questions together with the results of the midterm test.

We study the translationally invariant perturbations along the branes in those backgrounds and calculate quasinormal frequencies numerically. These frequencies should determine the thermalization time scales in the dual Yang-Mills theories.

description: Distance learning has become the only solution for learning in the current Covid-19 pandemic outbreak. A more straightforward form of distance learning with the utilization of telepresence and cloud-based productivity tools was apparent in many institutions. The present study investigated this phenomenon and ask, “What factors affect students’ acceptance of distance learning during school closures due to COVID-19?”. An extended Unified Theory of Acceptance and Use of Technology was employed to answer the research question, with 156 students participating in the study. The result revealed that Effort Expectancy (EE) has the biggest effect on students’ acceptance of distance learning during school closures (β=0.372, p<0.001). Additionally, the extended variable of Socia l Presence (SP) was also showing great effects on students' acceptance (β=0.296, p<0.001). However, one of the UTAUT constructs, Facilitating Conditions, was found to have no effect on students' acceptance. Practical implications for schools and distance learning program managers were discussed to provide insight on improving a distance learning program. This study contributes to the body of knowledge on learning technologies as well as on how society, especially in the educational sector, should continue despite the current pandemic crisis.

description: Ly$α$ line emission from the Loeb-Rybicki (LR) halo, which is the expanding HI IGM (intergalactic medium) around the first star clusters and the ionized interstellar medium, is investigated by solving a radiative transfer problem. While the initial scattering optical depth is $\sim 10^5$ for the Ly$α$ photons, most of the Ly$α$ photons can escape when the cumulative frequency-shift due to the expansion of the HI IGM becomes significantly large. The current paper improves upon previous treatments of the scattering processes and the opacity for the Ly$α$ transfer. Confirming the previous results of the LR halo, we investigate the effect of the aspherical expansion of the IGM. The asphericity is hypothesized to follow the initial stage of the gravitational deceleration to form the large scale filamentary structure of the Universe. According to our results, the effect of the asphericity lets the peak wavelength of the line profile shift to longer wavelengths and the FWHM of the profile become wider than those of the spherically expanding model. To detect these features is meaningful if we are interested in the initial evolution of the large scale structure, since they reflect the dynamical properties of the IGM at that time. Furthermore, given the recent discovery of the high redshift cosmological reionization, we briefly comment on the effects of the redshift and the cosmological parameters on the line profile.

For both flat and stepped interfaces we observed order in the AF above the Neel temperature, with the AF spins aligning collinearly with the F moments. In the case of the stepped interface there is a transition from collinear to perpendicular alignment of the F and AF spins at a lower temperature.

description: In an attempt to successfully teach students online during a pandemic, it is imperative to investigate to what extent students and teachers are prepared and ready for the adoption of such an approach, as it is difficult to change the educational scenario in Pakistan. The objective of this paper was to identify the degree of readiness and preparedness of students and teachers for implementation of online classes in a crisis situation together-with the experiences of students, teachers and parents in application of online classes during COVID-19. A self-developed online questionnaire, having three separate segments, one each to collect data from students, parents and teachers of private primary and secondary schools of Punjab was used. A sample of size 262 (students 112 teachers 76 and parents 74) was selected through convenient sampling technique. Statistical data analysis, both descriptive (frequencies and percentages) and inferential (Chi-square), was done. The study indicated lack of availability of smooth and fast Internet access at home. Students were required to learn their roles of self-management, to troubleshoot technological issues online without parental assistance and be able to complete their tasks independently. Majority of the parents agreed on temporary continuation of online sessions by schools. This study provides a comprehensive understanding of students and teachers’ role, together-with parents’ experience, in online sessions and discusses the possibilities of using technologies in education as it depicts the degree and key traits of online sessions for students and teachers needed for readiness and preparedness by private schools during pandemic.

description: The implementation of programs for feeding calves is one of the ways to achieve greater efficiency in milk production. The objective of this work was to analyze the cost of feeding and to evaluate the behavior of calves fed three commercial milk substitutes until the weaning stage. One hundred and twenty Holstein calves were randomly selected, which were separated from the mother at birth and housed individually in previously washed and disinfected wooden cages. The treatments were as follows: A: four L and B: six L milk with 22% crude protein, C: six L milk with 22.5% crude protein, and D: six L milk with 26% crude protein. The economic analysis included the price of the three substitutes and the cost of the initiator concentrate. The variables considered to estimate productivity were evaluated at birth and weaning, including: weight and height at the cross, daily gain and total weight gain. The daily weight gain was calculated by dividing the total weight gain by the number of days in lactation. Statistical analysis of the variables was performed using an analysis of variance and the comparison of means was performed with the Tukey test. The value of (P< 0.05) was used to consider statistical difference. Regarding the cost of food, treatment A was the cheapest and the least efficient while the treatment C was the most expensive and efficient. There was no statistical difference (P<0.05) in height at the cross at birth, weaning and birth weight; In the case of daily and total weight gain statistical difference was observed (P<0.01). Greater growth can be expected in heifers receiving a milk replacer that meets nutritional needs.

description: Peer review can be used as a teaching methodology to improve students’ learning and critical thinking. However teachers have many concerns about the reliability and validity of students’ grading. The paper describes the application of peer review as a teaching strategy to the large course of Biomedical Informatics in the School of Medicine at the University of Florence. The aim of the study was twofold: (I) assessing the validity of students’ reviews, calculating the correlation between students’ assigned score and instructor’s assigned score; (II) assessing the validity of student’s self-evaluation, calculating the correlation between student’s assigned score and teacher’s assigned score. To this aim a statistical analysis was performed. The results showed a moderate concordance between the marks assigned by peers and those assigned by the instructor. Neverthless the comparison between the teacher median and the peer-review median shows a minimal difference that has almost no effect on changing the final grade. Instead, there was poor concordance between the marks attributed by the instructor and those relating to the student’s self-evaluation.. Even if further studies are needed, the promising results can begin to dispel teachers’ concerns about students’ grading skills that prevent the application of peer review. On such basis, the use of peer review systems can streamline the application of peer.review in classes with a high number of students reducing the workload on the teacher.

Magnetic Surfaces in Stationary Axisymmetric General Relativity

Year: 2004
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: In this paper a new method is derived for constructing electromagnetic surface sources for stationary axisymmetric electrovac spacetimes endowed with non-smooth or even discontinuous Ernst potentials. This can be viewed as a generalization of some classical potential theory results, since lack of continuity of the potential is related to dipole density and lack of smoothness, to monopole density. In particular this approach is useful for constructing the dipole source for the magnetic field. This formalism involves solving a linear elliptic differential equation with boundary conditions at infinity. As an example, two different models of surface densities for the Kerr-Newman electrovac spacetime are derived.

description: Die erfolgreiche Durchführung des Praxisprojekts zum Lösen von Textaufgaben im Bereich des Sachrechnens und andererseits der erstaunliche Erfolg von Mathematikunterricht in fünf Monaten von der landesweit schlechtesten Klasse von Schweden, publiziert im GEO-Heft im Februar 2011, sind Ausgangspunkt und Motivation dieser Masterarbeit.
 Folgende Frage dient als Leitfaden:
 Welche Kriterien sind massgebend für einen erfolgreichen, ressourcenorientierten Mathematikunterricht in der Primarschule?
 Diese Frage ist unterteilt in die beiden Unterfragen:
 - Was macht Mathematikunterricht erfolgreich?
 - Welche Kriterien muss die Sprache erfüllen?
 Nebst dem Herausfiltern der Faktoren, die die LeMa-Methode zum Lösen von mathematischen Textaufgaben im Praxisprojekt so erfolgreich gemacht hat, werden weitere Methoden dazu untersucht.
 Nicht nur Textaufgaben, sondern der ganze Mathematikunterricht der Primarschule wird nun in den Fokus genommen. Was macht die Schwierigkeiten beim Mathematiklernen aus und welche Rolle spielt die Sprache dabei? Ausgehend von diesen Hürden werden praktische Hinweise gegeben, wie der Mathematikunterricht erfolgreich gestaltet werden kann und wie ein sprachsensibler Unterricht aussehen könnte. Aus empirischen Forschungen und didaktischer Literatur ebenso wie aus Medienberichten über den faszinierenden Erfolg des Lehrers Stavros Louca in Schweden und aus psychologischen Schriften wurden erfolgsrelevante und misserfolgsrelevante Kriterien herausfiltriert und zu konkreten Hinweisen für erfolgreichen Mathematikunterricht verdichtet. Dabei hat sich gezeigt, dass die Ansprüche an eine Lehrperson sehr hoch sind. Herauszufinden, was es braucht, dass Kinder in Mathematik erfolgreich sein können, ist das eine. Viel schwieriger jedoch ist die Umsetzung dieser Anliegen, stellen sie doch sehr hohe Ansprüche an die fachlich-didaktischen sowie sozial-kommunikativen Kompetenzen einer Lehrperson sowie ein grosses Mass an engagierter Hingabe, um die intrinsische Motivation der Kinder zu erhalten, so dass Lernzuwachs stattfinden kann.
 Als Leser und Leserinnen stehen Lehrpersonen im Fokus, die an der Primarschule Mathematik unterrichten und daran interessiert sind, ihren Unterricht zu reflektieren.

description: We present the kinematics of the molecular gas in the barred spiral galaxy M83 (NGC5236). The study is based on ^{12}CO(J=1--0 and 2--1) observations with the Swedish-ESO Submillimetre Telescope (SEST). Iso-velocity maps of the entire optical disk, 10'x10' or 13x13 kpc, are produced. They show the pattern of an inclined, rotating disk, but also the effects of streaming motions along the spiral arms. A dynamical mass of about 6x10^10 M_sun is estimated by fitting the rotation curve of an exponential disk model to these data. The gas constitutes about 13% of the disk mass. The pattern speed is determined from the residual velocity pattern The locations of various resonances are discussed. The molecular gas velocity dispersion is determined, and a trend of decreasing dispersion with increasing galactocentric radius is found. A total gas (H_2+HI+He) mass surface density map is presented, and compared to the critical density for star formation of an isothermal gaseous disk. The critical density is exceeded in the spiral arms, but not in the interarm regions. The locations of Giant Molecular Associations (GMAs) and HII regions are consistent with this scenario of dynamically induced star formation.

description: Contrary to previous claims, it is shown that, for an ensemble of either single-particle systems or multi-particle systems, the realistic interpretation of a superposition state that mathematically describes the ensemble does not imply that the ensemble is a mixture. Therefore it cannot be argued that the realistic interpretation is wrong on the basis that some predictions derived from the mixture are different from the corresponding predictions derived from the superposition state.

[Methods] The Latin square design was adopted to investigate the effect of sowing rate + fertilizer amount, sowing rate + light on the root and seed yield of C. glandulosum Boiss. et Huet. The changes in the seed and root yield of C. glandulosum Boiss. et Huet. under the influence of sowing rate, N application rate and light were compared and analyzed. [Results] In Moyu, Hotan and similar areas, the suitable sowing rate of C. glandulosum Boiss. et Huet. was 4.5-15.0 kg/ha. Without applying fertilizer, if the main purpose is to harvest the roots of C. glandulosum Boiss. et Huet, its sowing rate is recommended to be 7.5-15.0 kg/ha; and if the main purpose is to harvest the seeds of it, the sowing rate is recommended to be 4.5-7.5 kg/ha. Shading will affect the root and seed yield of C. glandulosum Boiss. et Huet. At the fertilizer amount of 450 kg/ha, the optimal sowing rate of C. glandulosum Boiss. et Huet. is 4.5 kg/ha. [Conclusions] This study provides a certain reference basis for artificial cultivation of C. glandulosum Boiss. et Huet.
Thermodynamic behaviour of magnetocaloric quantities in spin-1/2 Ising square trilayer

description: A spin-1/2, Ising trilayered ferrimagnetic system on square Bravais lattice is studied, employing Monte-Carlo simulation with the single spin-flip Metropolis algorithm. The bulk of such a system is formed by three layers, each of which is composed entirely either by A or B type of atoms, resulting in two distinct compositions: ABA and AAB and two different types of magnetic interactions: ferromagnetic between like atoms and antiferromagnetic between unlike atoms. For such systems, Inverse Absolute of Reduced Residual Magnetisation is the absolute value of the ratio of the extremum of the magnetisation in between compensation and critical points and the saturation magnetisation. Variation of relative interaction strengths in the Hamiltonian, for a range of values, leads to the shift of compensation point and critical point and changes in the magnitude of Inverse absolute of Reduced Residual magnetisation. Probable mathematical forms of dependences of the Inverse absolute of Reduced Residual magnetisation and temperature interval between the compensation and critical points on controlling parameters were proposed in the absence of applied magnetic field and have obtained phase diagrams for both types of configurations from these relations. This alternative description of the simulated systems may help technologists design magnetocaloric materials according to desired characteristics.

description: Paludiculture is known as an alternative approach to cultivate peatland sustainably. This technique does not require land drainage. The method enables sustainable peat swamp forest cultivation that protects the ecosystem through peat rehabilitation, blocking the water channel, and planting the native species (Joosten et al., 2012). This practice is expected to produce biomass (the biological materials in plants) that will support peat formation in the long run.
Dark soliton-like magnetic domain walls in a two-dimensional ferromagnetic superfluid

description: We report a stable magnetic domain wall in a uniform ferromagnetic spin-1 condensate, characterized by the magnetization having a dark soliton profile with nonvanishing superfluid density. We find exact stationary solutions for a particular ratio of interaction parameters with and without magnetic fields, and develop an accurate analytic solution applicable to the whole ferromagnetic phase. In the absence of magnetic fields, this domain wall relates various distinct solitary excitations in binary condensates through $\textrm{SO}(3)$ spin rotations, which otherwise are unconnected. Remarkably, studying the dynamics of a quasi-two-dimensional (quasi-2D) system we show that standing wave excitations of the domain wall oscillate without decay, being stable against the snake instability. The domain wall is dynamically unstable to modes that cause the magnetization to grow perpendicularly while leaving the domain wall unchanged. Real time dynamics in the presence of white noise reveals that this "spin twist" instability does not destroy the topological structure of the magnetic domain wall.

Electronic structure and magnetism for FeSi$_{(1-x)}$Ge$_x$ from supercell calculations

description: Recent studies of FeSi$_{(1-x)}$Ge$_x$, which found a transition from an insulating to a magnetic metallic state near $x$=0.25, have revived the discussion about the role of strong correlation in these systems. Here are spin polarized band calculations made for 64-atom supercells of FeSi$_{(1-x)}$Ge$_x$ for different $x$ and different volumes for large $x$. The results show that the small band gap in FeSi is closed for $x \geq 0.3$, because of both substitutional disorder and increased volume. Ferromagnetism appears near this composition and becomes enforced for increasing $x$. The $x$-dependence of the electronic specific heat can be understood from the exchange splitting of the density-of-states near the gap. Strong volume dependencies for the properties of FeGe suggest experiments using pressure instead of $x$ for investigations of the gap.

description: We simulate vortices in superconductors interacting with two-dimensional arrays of triangular traps. We find that, upon application of an ac drive, a net dc flow can occur which shows current reversals with increasing ac drive amplitude for certain vortex densities, in agreement with recent experiments and theoretical predictions. We identify the vortex dynamics responsible for the different rectification regimes. We also predict the occurrence of a novel transverse rectification effect in which a dc flow appears that is transverse to the direction of the applied ac drive.

description: By extending the Bielefeld LGS (Lattice Gauge Simulation) color singlet interaction, we find that the masses of pi, sigma, rho and a_1 excitations, 32 degrees of freedom in all, go to zero (in the chiral limit) as T -> T_c. This result indicates a smooth phase transition at T_c, at which from above the masses and couplings of mesons vanish `a la Brown-Rho scaling. We discuss that our scenario successfully explains the STAR (STAR Collaboration) rho^0/pi^- ratio in Au-Au peripheral collisions at RHIC.

Spatially extended K I 7699 emission in the nebula of VY CMa: Kinematics and geometry

description: Long-slit echelle spectra reveal bright extended emission from the K I lambda7699 resonance line in the reflection nebula surrounding the extreme red supergiant VY Canis Majoris. The central star has long been known for its unusually-bright K I emission lines, but this is the first report of intrinsic emission from K I in the nebula. The extended emission is not just a reflected spectrum of the star, but is due to resonant scattering by K atoms in the outer nebula itself, and is therefore a valuable probe of the kinematics and geometry of VY CMa's circumstellar environment. Dramatic velocity structure is seen in the long-slit spectra, and most lines of sight intersect multiple distinct velocity components. A faint ``halo'' at large distances from the star does appear to show a reflected spectrum, however, and suggests a systemic velocity of +40 km/s with respect to the Sun. The most striking feature is blueshifted emission from the filled interior of a large shell seen in images; the kinematic structure is reminiscent of a Hubble flow, and provides strong evidence for asymmetric and episodic mass loss due to localized eruptions on the star's surface.

Mobility in the livable city : a case study of Skytrain's impact on mobility and livability in Vancouver, BC
Creators: name: Olson, Kristin Michiko
Publisher: name: University of British Columbia
Year: 2011

description: Vancouver has been cited as an exemplar of successful urban planning, and newspaper articles, surveys, Best Of Lists and academic reports would seem to agree. The city has become a brand of "livability" that is packaged and sold as the "Vancouver Model" of urban planning. One of the early outcomes of the city's livability-centred planning ethos was the construction of an enormously expensive light rail transit line, the Sky Train, which has subsequently become an icon of the city's livability. In this project, I investigate the extent to which Vancouver's substantial investment into automated light rail has facilitated efficient and equitable urban mobility, a key feature of livability. I argue that the broader context of the Vancouver Model built on a flourishing postindustrial economy is shaping the geography of urban mobility just as much as the light rail line itself. I argue that this is related to the suite of changes in Vancouver's urban form in the past number of years, which have bifurcated into two related but unacknowledged categories: an official face of urbanism comprising the feted forms that have come to be known as "The Vancouver Model"; and an unrecognized side that is part and parcel of the former, involving dramatic re-configurations in rental housing and the social geography of the city-region. I present preliminary evidence that suggests that tensions between the official and unacknowledged sides of Vancouver's urbanism are shaping the region's geography of urban mobility to an extent beyond the influence of the city's transportation planning and heavy investments into automated light rail.

description: Here we present an efficient quantum algorithm to generate an equivalent many-body state to Laughlin's $ν=1/3$ fractional quantum Hall state on a digitized quantum computer. Our algorithm only uses quantum gates acting on neighboring qubits in a quasi-one-dimensional setting, and its circuit depth is linear in the number of qubits, i.e., the number of Landau orbitals in the second quantized picture. We identify correlation functions that serve as signatures of the Laughlin state and discuss how to obtain them on a quantum computer. We also discuss a generalization of the algorithm for creating quasiparticles in the Laughlin state. This paves the way for several important studies, including quantum simulation of nonequilibrium dynamics and braiding of quasiparticles in quantum Hall states.

description: We develop a microscopic description of an electron-doped two-dimensional semiconductor embedded in a microcavity. Specifically, we investigate the interactions between exciton-polaritons and electrons for the case where the interactions between charges are strongly screened and the system is spin polarized. As a starting point, we obtain an analytic expression for the exciton-polariton wave function, and we relate the microscopic parameters of the light-matter system to experimentally measurable quantities, such as the Rabi coupling and the cavity photon frequency. We then derive the polariton-electron interaction within the standard Born approximation and compare it with the exact polariton-electron scattering $T$ matrix that we obtain from a diagrammatic approach that has proven highly successful in the context of nuclear physics and ultracold atomic gases. In particular, we show that the Born approximation provides an upper bound on the polariton-electron coupling strength at vanishing momentum. Using our exact microscopic calculation, we demonstrate that polariton-electron scattering can be strongly enhanced compared to the exciton-electron case, which is the opposite of that expected from the Born approximation. We furthermore expose a resonance-like peak at scattering momenta near the polariton inflection point, whose size is set by the strength of the light-matter coupling. Our results arise from the non-Galilean nature of the polariton system and should thus be applicable to a range of semiconductor microcavities such as GaAs quantum wells and atomically thin materials.
