description: Spin-dependent electronic transport through a quantum dot side-coupled to two quantum dots and attached to ferromagnetic leads with collinear (parallel and antiparallel) magnetizations is analyzed theoretically. The intra-dot Coulomb correlations are taken into account, whereas the inter-dot ones are neglected. Transport characteristics, i.e. conductance and tunnel magnetoresistance associated with the magnetization rotation from parallel to antiparallel configurations, are calculated by the noneqiulibrium Green function technique. The Green functions are derived by the equation of motion method in the Hartree-Fock approximation. The conductance spectra are shown to reveal features similar to the Dicke resonance in atomic physics.

description: The BL Lac PG 1553+113 has been continuously monitored in gamma rays with Fermi-LAT for over 9 years. Its updated light curve now includes 5 iterations of a main pattern comprising a high peak and a longer trough, with a period P \sim 2.2 yr. Our analysis of 2015-2017 data confirms the occurrence in January 2017 of a new peak fitting in the previous trend. In addition, we identify secondary peaks ("twin peaks") that occur in closely symmetric pairs on both sides of most main peaks, including the last one; their occurrence is supported by correlated X-ray outbursts. We stress that the above features strongly point to binary dynamics in a system of two black holes (BHs) of some 10^8 and 10^7 M_sun. At periastron the smaller BH periodically stresses the jet j_1 launched by the heavier companion, and triggers MHD-kinetic tearing instabilities. These lead to magnetic reconnections and to acceleration of electrons that produce synchrotron emission from the optical to X-ray bands, and inverse Compton scattering into the GeV range. For the origin of the twin peaks we discuss two possibilities: a single-jet model, based on added instabilities induced in j_1 by the smaller companion BH on its inner orbital arc; and a two-jet model with the smaller BH supporting its own, precessing jet j_2 that contributes lower, specific GeV emissions. Such behaviors combining time stability with amplitude variations betray plasma instabilities driven in either jet by binary dynamics, and can provide a double signature of the long-sought supermassive BH binaries.

description: Context. Accreting ultracompact binaries contain a white dwarf that is accreting from a degenerate object and have orbital periods shorter than 65 minutes.
 Aims. The aims of this letter are to report the discovery and the orbital period of four new eclipsing accreting ultracompact binaries found using the Zwicky Transient Facility, and to discuss their photometric properties.
 Methods. We searched through a list of 4171 dwarf novae compiled using the Zwicky Transient Facility and used the Box Least Square method to search for periodic signals in the data.
 Results. We found four new eclipsing accreting ultracompact binaries with orbital periods between 25.9-56 minutes, one of which is previously published as an AM CVn, while the other three systems are new discoveries. The other two shorter period systems are likely also AM CVn systems, while the longest period system with a period of 56 minutes shows multiple super-outbursts observed in two years which is more consistent with it being a Helium-CV.

description: El acoso laboral afecta los derechos fundamentales de los trabajadores, por tal razón, el legislador consagró en la ley 1010 de 2006 unas herramientas para resarcir los derechos de las víctimas de este fenómeno, dentro de las que se encuentra un fuero que prohíbe que el empleador termine la relación laboral por el término de seis meses. Esta estabilidad laboral reforzada tratándose de empleados de libre nombramiento y remoción que por su naturaleza tienen una estabilidad precaria ya que pueden ser removidos del cargo de forma discrecional a través de acto administrativo inmotivado cuando el nominador así lo estime conveniente, genera una tensión con la facultad discrecional de insubsistencia. A pesar de que la administración cuenta con la prerrogativa de no expresar en el acto de insubsistencia las razones de su decisión, cuando se está ante un conflicto de mobbing debe abstenerse de retirar del cargo al trabajador, y de ser necesaria la desvinculación motivar directamente el acto administrativo señalando las causas del retiro, o dejando las anotaciones de las razones que la llevaron a tomar esa decisión en la hoja de vida del funcionario, en aras de desvirtuar que la finalización de la relación laboral fue consecuencia del acoso laboral.
description: The work harassment affect the fundamental rights of workers, for that reason the legislator establish the 1010 law of 2006 a group of tools to restore the rights of the victims of this fenomena, within which there is a privilege that prohibit the employer end the work relationship for a period of six months. This reinforeced emloyment stability, by means of free designation and removal workers that due to their nature have an uncertain stability and can be removed from their possition by discretionary unmotivated administrative act when the nominator consider it convenient, generates a tension with the discretional unsubsistance faculty. Despite the administration has the prerogative of not expressing the reasons for its decision in the act of unsubsistence, when they face with a mobbing conflict, they must refrain from removing the worker from the position. And if the separation is necessary, directly motivate the administrative act indicating the causes of the dismiissal, or making notes of the reasons that led to making that decision in the official's resume, in order to disprove that the termination of the employment relationship was a consequence of workplace harassment.

Die Studie untersucht spezifisch die Arbeitserfahrungen und Werthaltungen der BKA-Beschäftigten, da das BKA als Zentralstelle der deutschen Polizei andere Rahmenbedingungen aufweist als andere Polizeien bei Bund und Ländern. Die Studie zeigt, dass Vorurteile und Diskriminierung weiterhin Themen sind, mit denen sich das BKA auseinandersetzen muss. Obwohl die Neigung zu autoritärem Denken oder zur Abwertung bestimmter sozialer Gruppen am BKA durchschnittlich oder sogar unterdurchschnittlich zu sein scheint, haben einige Beschäftigte diskriminierendes Verhalten am Arbeitsplatz beobachtet. Die Studie identifiziert auch Faktoren, die maßgeblich zur Arbeitszufriedenheit der BKA-Beschäftigten beitragen, wie unbürokratische Arbeitsprozesse, transparente Karriereplanung und sinnstiftende Führungskräfte

description: With strongly bound and stable excitons at room temperature, single-layer, two-dimensional organic-inorganic hybrid perovskites are viable semiconductors for light-emitting quantum optoelectronics applications. In such a technological context, it is imperative to comprehensively explore all the factors --- chemical, electronic and structural --- that govern strong multi-exciton correlations. Here, by means of two-dimensional coherent spectroscopy, we examine excitonic many-body effects in pure, single-layer (PEA)$_2$PbI$_4$ (PEA = phenylethylammonium). We determine the binding energy of biexcitons --- correlated two-electron, two-hole quasiparticles --- to be $44 \pm 5$\,meV at room temperature. The extraordinarily high values are similar to those reported in other strongly excitonic two-dimensional materials such as transition-metal dichalchogenides. Importantly, we show that this binding energy increases by $\sim25$\% upon cooling to 5\,K. Our work highlights the importance of multi-exciton correlations in this class of technologically promising, solution-processable materials, in spite of the strong effects of lattice fluctuations and dynamic disorder.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: We present new parallax measurements of 7 long-period (> 10 days) Milky Way Cepheids (SS CMa, XY Car, VY Car, VX Per, WZ Sgr, X Pup and S Vul) using astrometry from spatial scanning of WFC3 on HST. Observations were obtained at 6 month intervals over 4 years. The distances are 1.7--3.6 kpc with a mean precision of 45 microarcseconds and a best of 29 microarcseconds (SNR = 14). The accuracy of the parallaxes is demonstrated through independent analyses of >100 reference stars. This raises to 10 the number of long-period Cepheids with significant parallax measurements, 8 obtained from this program. We also present high-precision F555W, F814W, and F160W magnitudes of these Cepheids, allowing a direct, zeropoint-independent comparison to >1800 extragalactic Cepheids in the hosts of 19 SNeIa. This sample addresses two outstanding systematic uncertainties affecting prior comparisons of Milky Way and extragalactic Cepheids used to calibrate H_0: their dissimilarity of periods and photometric systems. Comparing the new parallaxes to their predicted values derived from reversing the distance ladder gives a ratio (or independent scale for H_0) of 1.037+/-0.036, consistent with no change and inconsistent at the 3.5 sigma level with a ratio of 0.91 needed to match the value predicted by Planck+LCDM. Using these data instead to augment the Riess et al. (2016) measurement of H_0 improves the precision to 2.3%, yielding 73.48+/-1.66 km/s/Mpc, and tension with Planck+LCDM increases to 3.7 sigma. The future combination of Gaia parallaxes and HST spatial scanning photometry of 50 Milky Way Cepheids can support a < 1% calibration of H_0.

description: In 1992 a puzzling transition was discovered in simulations of randomly coupled limit-cycle oscillators. This so-called volcano transition has resisted analysis ever since. It was originally conjectured to mark the emergence of an oscillator glass, but here we show it need not. We introduce and solve a simpler model with a qualitatively identical volcano transition and find, unexpectedly, that its supercritical state is not glassy. We discuss the implications for the original model and suggest experimental systems in which a volcano transition and oscillator glass may appear.

description: Plasmoid-mediated reconnection plays a fundamental role in different solar atmospheric phenomena. Numerical reproduction of this process is therefore essential for developing robust solar models. Our goal is to assess plasmoid-mediated reconnection across various numerical resistivity models in order to investigate how plasmoid numbers and reconnection rates depend on the Lundquist number. We used the Bifrost code to drive magnetic reconnection in a 2D coronal fan-spine topology, carrying out a parametric study of several experiments with different numerical resolution and resistivity models. We employed three anomalous resistivity models: (1) the original hyper-diffusion from Bifrost, (2) a resistivity proportional to current density, and (3) a resistivity quadratically proportional to electron drift velocity. For comparisons, experiments with uniform resistivity were also run. Plasmoid-mediated reconnection is obtained in most of the experiments. With uniform resistivity, increasing the resolution reveals higher plasmoid frequency with weaker scaling to the Lundquist number, obtaining 7.9-12 plasmoids per minute for $S_L\in[1.8 \times 10^4, 2.6\times 10^5]$ with a scaling of $S_L^{0.210}$ in the highest-resolution resistivity cases, transcending into Petschek reconnection in the high-$S_L$ limit and Sweet-Parker reconnection in the low-$S_L$ limit. Anomalous resistivity leads to similar results even with lower resolution. The drift-velocity-dependent resistivity excellently reproduces Petschek reconnection for any Lundquist number, and similar results are seen with resistivity proportional to current-density. Among the different resistivity models applied on the given numerical resolution, the hyper-diffusion model reproduced plasmoid characteristics in closest resemblance to those obtained with uniform resistivity at a significantly higher resolution.

description: A universal topological marker has been proposed recently to map the topological invariants of Dirac models in any dimension and symmetry class to lattice sites. Using this topological marker, we examine the conditions under which the global topological order, represented by the spatially averaged topological marker, remains unchanged in the presence of disorder for 1D and 2D systems. We find that if an impurity corresponds to varying a nonzero matrix element of the lattice Hamiltonian, regardless the element represents hopping, chemical potential, pairing, etc, then the average topological marker is conserved. However, if there are many strong impurities and the average distance between them is shorter than a correlation length, then the average marker is no longer conserved. In addition, strong and dense impurities can be used to continuously interpolate between one topological phase and another. A number of prototype lattice models including Su-Schrieffer-Heeger model, Kitaev chain, Chern insulators, Bernevig-Hughes-Zhang model, and chiral p-wave superconductors are used to elaborate the ubiquity of these statements.

This is why on the verge of an unprecedented climate crisis it is urgent to comply with the Paris Agreement. Taking into account that 100% of the municipalities in Colombia will be affected with the projected climate change, and from the political-administrative perspective these municipalities are the fundamental cell of the State at the local level. The framework in which the competences decentralization in Colombia is developed, its implications in the climate agenda and the challenges that the National Environmental System (SINA) must face to lead a national policy on climate change with a territorial approach is addressed from a critical viewpoint in this chapter.

description: Sparse Subspace Clustering (SSC) is a popular unsupervised machine learning method for clustering data lying close to an unknown union of low-dimensional linear subspaces; a problem with numerous applications in pattern recognition and computer vision. Even though the behavior of SSC for complete data is by now well-understood, little is known about its theoretical properties when applied to data with missing entries. In this paper we give theoretical guarantees for SSC with incomplete data, and analytically establish that projecting the zero-filled data onto the observation pattern of the point being expressed leads to a substantial improvement in performance. The main insight that stems from our analysis is that even though the projection induces additional missing entries, this is counterbalanced by the fact that the projected and zero-filled data are in effect incomplete points associated with the union of the corresponding projected subspaces, with respect to which the point being expressed is complete. The significance of this phenomenon potentially extends to the entire class of self-expressive methods.
DECARBONIZING THE GLOBAL ECONOMY: IS CARBON BORDER ADJUSTMENT AN EFFECTIVE INSTRUMENT?
Creators: name: Wang, ManQing
Publisher: name: My University
Year: 2022

description: In recent decades, the rising frequency of extreme weather events and their deadly repercussions has prompted an increasing number of governments to explore measures to mitigate the effects of climate change by reducing greenhouse-gas emissions. In the absence of a concerted global effort, many advanced economies have unilaterally implemented carbon-reduction programs that reflect their unique capacities and legislative circumstances. However, these national (or even sub national) carbon dioxide reduction measures have resulted in issues such as carbon leakage and loss of competitiveness. Given this problem, the border carbon adjustments (BCA) mechanism has caught the attention of international policymakers as a viable policy instrument to address the challenges raised by unilateral carbon abatement measures. This paper’s goal is to take into account all the different viewpoints and examine the effects of a BCA implementation comprehensively and exhaustively. In the absence of global environmental cooperation, this research suggests that, notwithstanding its flaws and legal difficulties, BCA is the optimal tool for most industrialized countries with stringent abatement policies. The environmental and economic effectiveness, legal acceptability, and political viability of border adjustment policies depend on their particular design. The value of any BCA design also varies depending on a country's economic and political context. Consequently, the design of BCA should be based on an appraisal of each country's specific conditions and factors. While the bulk of this research explores the BCA from an international viewpoint, Canada is used as a case study to see if the BCA would be a beneficial instrument for a trade-dependent, small, open economy that assumes world import and export prices.

description: El grupo de investigación en Justicia Constitucional del Departamento de Derecho Constitucional de la Universidad Externado de Colombia se complace en publicar el libro Control automático de constitucionalidad. Este texto forma parte de la serie Garantías judiciales de la Constitución. Con esta serie, la Universidad busca contribuir al estudio y examen crítico del régimen procesal de los distintos mecanismos judiciales de protección de derechos fundamentales y de control de constitucionalidad previstos por el ordenamiento jurídico colombiano. En este libro encontrarán un estudio procesal exhaustivo sobre el control automático de constitucionalidad. En concreto, esta obra contiene cinco artículos que examinan el control de constitucionalidad de proyectos de leyes estatutarias, leyes aprobatorias de tratados internacionales, decretos legislativos, convocatorias de referendo y asambleas constituyentes, y finalmente las normas adoptadas por medio del procedimiento legislativo especial de paz (fast-track). De esta manera, da cuenta, en profundidad, de las principales cuestiones sustanciales y vicisitudes procesales de este mecanismo.

description: From a systematic study of thermal and charge transport in various single crystals of compensated topological insulators we identify the evolution of a large low-temperature thermal Hall effect as a characteristic common feature. In order to separate phononic and electronic contributions in the measured longitudinal and transverse thermal conductivity, the electronic contributions are estimated from corresponding electrical resisivity and Hall effect measurements on the same samples by using the Wiedemann-Franz law. As may be expected for charge-compensated topological insulators the longitudinal thermal conductivity is phonon-dominated in all samples. However, we also find a pronounced field-linear thermal Hall effect that becomes most pronounced in the low-temperature range, where all samples are good electrical insulators. This indicates an underlying phononic mechanism of the thermal Hall effect and in this respect the topological insulators resemble other, mainly ionic, insulators, which have been reported to show a phonon-induced thermal Hall effect, but its underlying phononic mechanism remains to be identified. Our observation of a comparable thermal Hall ratio in topological insulators supports a theoretical scenario that explains a thermal Hall effect through skew scattering on charged impurities.

description: X-ray properties of the stellar population in the Carina OB1 association are examined with special emphasis on early-type stars. Their spectral characteristics provide some clues to understanding the nature of X-ray formation mechanisms in the winds of single and binary early-type stars. A timing and spectral analysis of five observations with XMM-Newton is performed using various statistical tests and thermal spectral models. 235 point sources have been detected within the field of view. Several of these sources are probably pre-main sequence stars with characteristic short-term variability. Seven sources are possible background AGNs. Spectral analysis of twenty three sources of type OB and WR 25 was performed. We derived spectral parameters of the sources and their fluxes in three energy bands. Estimating the interstellar absorption for every source and the distance to the nebula, we derived X-ray luminosities of these stars and compared them to their bolometric luminosities. We discuss possible reasons for the fact that, on average, the observed X-ray properties of binary and single early type stars are not very different, and give several possible explanations.

description: We calculate the neutron matter equation of state at finite temperature based on low-momentum two- and three-nucleon interactions. The free energy is obtained from a loop expansion around the Hartree-Fock energy, including contributions from normal and anomalous diagrams. We focus on densities below saturation density with temperatures T <= 10 MeV and compare our results to the model-independent virial equation of state and to variational calculations. Good agreement with the virial equation of state is found at low density. We provide simple estimates for the theoretical error, important for extrapolations to astrophysical conditions.

The effect of the COVID-19 induced uncertainty on the Canadian economy
Creators: name: El Mansouri, Mouad
Publisher: name: My University
Year: 2020

description: One of the most challenging factors that is characterizing the current economic crisis is the COVID-19 induced uncertainty. Policymakers and economists play a crucial role in implementing an effective and accommodative economic policy that would be able to soften the blow caused by this notorious virus. The aim of this paper is to estimate the impact of COVID19’s uncertainty on the Canadian real economy through the use of a Structural Vector Autoregressive model with exogenous variables (SVARX). To the best of our knowledge, no other study attempted to achieve the same objective. This paper demonstrates that the Canadian real economy will experience a significant slowdown due to the Covid-19 uncertainty as shown through the fall of the Canadian GDP. The inflation rate will be subjected to some deflationary pressures following the unexpected shock. Last but not least, the Bank of Canada will be expected to decrease its overnight interest rate in order to support the economic recovery.

description: True muonium (TM) -- the bound state of $μ^+μ^-$ -- has not been discovered yet. It was demonstrated that searching for TM via $γγ$ fusions in heavy ion collisions is feasible due to the enhancement of the atom number. We study the production of the true para-muonium (pTM) in the collisions of linearly polarized photons in the experiments of heavy-ion collisions, calculate the production rate as well as the transverse spectrum of pTM, and explore the discovery potential in nuclear experiments. Our results show that there is a significant correlation between the linearly polarized photon distribution and the transverse momentum distribution of pTM. The optimal kinematic region of the generated pTM is identified, which can provide a theoretical guide to the detection of pTM in experiments.

description: Abstract

Today, logistics industry is increasingly recognized as important role for economic growth in Thailand. As truck business facilitates door-to-door transportation, and it is fierce competition. In Thailand, it has currently 823,820 trucks as most of them are small and medium enterprises (SME). They have many problems and barriers to operate in dynamic businesses.  The paper examines problematic situations and evaluate competitiveness of Thai truck companies. It also analyses factors influence to enhance their competitive advantage. The literature is reviewed in area of truck performance and competitiveness. The questionnaire survey is conducted through 280 samplings and 232 returned with response rate at 82.8 percent. In-depth interview is conducted through 35 owners and top management. The validity and reliability are examined. The result reveals that most of them are SMEs and sufficiently lack logistics knowledge and skills, including access to financial resource and business networks. The study shows that knowledge, standard, network and professional are key success to increase their competitive advantage. As a result, they would effectively facilitate cost reduction, increasing responsiveness and higher service quality to customers. It also provides recommendations to facilitate Thai truck entrepreneurs to develop their higher standard and performance, including enhancing competitiveness.

description: Ship traffic in the Canadian Arctic nearly tripled between 1990 and 2015. The Government of Canada is developing a network of low-impact marine transportation corridors in the Arctic that encourages marine transportation traffic to use routes that pose less risk and minimize the impact on communities and the environment. The Low Impact Shipping Corridors will be a framework to guide future federal investments to support marine navigation safety in the North, including improved charting and increased hydrography, in partnership with Northerners. The corridors initiative is co-led by the Canadian Coast Guard, Transport Canada, and Canadian Hydrographic Service. Key considerations in the current prioritization of the Low Impact Shipping Corridors include identification of Inuit and Northerners’ perspectives on 1) the potential impact of marine vessels on marine areas used for cultural and livelihood activities, and on community members; and 2) potential management strategies for the corridors. This report reflects opinions gathered through participatory mapping, focus group discussions, and interviews with Coral Harbour community members who were identified by local organizations as key knowledge holders. This report was validated by the research participants.
