description: We consider Bloch electrons in the presence of the uniform electromagnetic field in two- and three-dimensions. It is renowned that the quantized Hall effect occurs in such systems. We suppose a weak and homogeneous electric field represented by the time-dependent vector potential which is changing adiabatically. The adiabatic process can be closed in the parameter space and a Berry phase is generated. In the system, one can define the macroscopic electric polarization whose time derivative is equivalent to the quantized Hall current and its conductivity is written by the Chern number. Then, the polarization is induced perpendicular to the electric field. We show that the induced polarization per a cycle in the parameter space is quantized and closely related to the Berry phase as well as the Chern number. The process is adiabatic and the system always remains the ground state, then, the polarization is quite different from the usual dielectric polarization and has some similarity to the spontaneous polarization in the crystalline dielectrics which is also written by the Berry phase. We also point out the relation between our results and the adiabatic pumping.

A plausible model of inflation driven by strong gravitational wave turbulence

description: It is widely accepted that the primordial universe experienced a brief period of accelerated expansion called inflation. This scenario provides a plausible solution to the horizon and flatness problems. However, the particle physics mechanism responsible for inflation remains speculative with, in particular , the assumption of a scalar field called inflaton. Furthermore, the comparison with the most recent data raises new questions that encourage the consideration of alternative hypotheses. Here, we propose a completely different scenario based on a mechanism whose origins lie in the nonlin-earities of the Einstein field equations. We use the analytical results of weak gravitational wave turbulence to develop a phenomenological theory of strong gravitational wave turbulence where the inverse cascade of wave action plays a key role. In this scenario, the space-time metric excitation triggers an explosive inverse cascade followed by the formation of a condensate in Fourier space whose growth is interpreted as an expansion of the universe. Contrary to the idea that gravitation can only produce a decelerating expansion, our study reveals that gravitational wave turbulence could be a source of inflation. The fossil spectrum that emerges from this scenario is shown to be in agreement with the cosmic microwave background radiation measured by the Planck mission.

description: We calculate the bispectrum of the gravitational field fluctuations generated during warm inflation, where dissipation of the vacuum potential during inflation is the mechanism for structure formation. The bispectrum is non--zero because of the self--interaction of the scalar field. We compare the predictions with those of standard, or `supercooled', inflationary models, and consider the detectability of these levels of non--Gaussianity in the bispectrum of the cosmic microwave background. We find that the levels of non--Gaussianity for warm and supercooled inflation are comparable, and over--ridden by the contribution to the bispectrum due to other physical effects. We also conclude that the resulting bispectrum values will be undetectable in the cosmic microwave background for both the MAP and Planck Surveyor satellites.

description: We consider Penrose limits of the Klebanov-Strassler and Maldacena-Nunez holographic duals to N =1 supersymmetric Yang-Mills. By focusing in on the IR region we obtain exactly solvable string theory models. These represent the nonrelativistic motion and low-lying excitations of heavy hadrons with mass proportional to a large global charge. We argue that these hadrons, both physically and mathematically, take the form of heavy nonrelativistic strings; we term them "annulons." A simple toy model of a string boosted along a compact circle allows us considerable insight into their properties. We also calculate the Wilson loop carrying large global charge and show the effect of confinement is quadratic, not linear, in the string tension.

Dementsprechend ist es notwendig, das Thema wissenschaftlich zu erforschen, um potenzielle Folgen besser abzuschätzen zu können. Es wird angestrebt, herauszufinden, welche Methoden der Heimarbeit dabei vordergründig angewandt werden, welche agilen Organisationsprinzipien für eine effiziente Arbeit im Homeoffice bereits in Benutzung genommen werden und welche konkreten Maßnahmen in der Zukunft geplant sind. Des Weiteren werden die für die Arbeitnehmer entstehenden Rahmenbedingungen wissenschaftlich ergründet, indem deren Situation vor und während der Pandemie nach bestimmten Kriterien, welche in einem späteren Abschnitt dieser Arbeit vorgestellt werden, miteinander verglichen werden. Es soll ergründet werden, wie gut oder schlecht Kulturmanager*innen auf die schnelle und unerwartete Umstellung auf Heimarbeit reagiert haben. Dementsprechend sollen besonders die pandemiebedingten Veränderungen in Arbeitsweise und Produktivität beleuchtet werden.

description: The increasing penetration level of energy generation from renewable sources is demanding for more accurate and reliable forecasting tools to support classic power grid operations (e.g., unit commitment, electricity market clearing or maintenance planning). For this purpose, many physical models have been employed, and more recently many statistical or machine learning algorithms, and data-driven methods in general, are becoming subject of intense research. While generally the power research community focuses on power forecasting at the level of single plants, in a short future horizon of time, in this time we are interested in aggregated macro-area power generation (i.e., in a territory of size greater than 100000 km^2) with a future horizon of interest up to 15 days ahead. Real data are used to validate the proposed forecasting methodology on a test set of several months.

description: For several classes of BPS vacua, we find a procedure to modify the PDEs that imply preserved supersymmetry and the equations of motion so that they still imply the latter but not the former. In each case we trace back this supersymmetry-breaking deformation to a distinct modification of the pure spinor equations that provide a geometrical interpretation of supersymmetry. We give some concrete examples: first we generalize the Imamura class of Mink6 solutions by removing a symmetry requirement, and then derive some local and global solutions both before and after breaking supersymmetry.

description: We present an improved approach for 3D object detection in point clouds data based on the Frustum PointNet (F-PointNet). Compared to the original F-PointNet, our newly proposed method considers the point neighborhood when computing point features. The newly introduced local neighborhood embedding operation mimics the convolutional operations in 2D neural networks. Thus features of each point are not only computed with the features of its own or of the whole point cloud, but also computed especially with respect to the features of its neighbors. Experiments show that our proposed method achieves better performance than the F-Pointnet baseline on 3D object detection tasks.

description: The essence of this study is to assess the impact of Micro credit on farmers’ poverty status in Kwara state, Nigeria. 50 users and 100 non-users of Micro credit facilities were randomly selected. Descriptive statistics was used to describe the socio-economic characteristics of the respondents. The determinants of poverty status of the farmers were analyzed using logistic model. The Foster-Greer-Thorbecke (FGT) model was used to analyze the extent of poverty among the farming households. The results show that majority of the users and non-users are married with 92% and 82% respectively. Majority (96%) of the users had some level of formal education while, majority (88%) of the non-users had no formal education. The FGT result shows that the poverty status of non-users is higher than that of the users. Age of the household head and the household size had positive effect on the household’s poverty status.
Density Weighted Angular Redshift Fluctuations: a New Cosmological Observable

description: We propose the use of angular fluctuations in the galaxy redshift field as a new way to extract cosmological information in the Universe. This new probe $δz (\hat{n})$ consists on the statistics of sky maps built by projecting redshifts under a Gaussian window of width $σ_z$ centred upon a redshift $z_{\rm obs}$, and weighted by the galaxy density field. We compute the angular power spectrum of the $δz (\hat{n})$ field in both numerical simulations and in linear perturbation theory. From these we find that the $δz (\hat{n})$ field: {\it (i)} is sensitive to the underlying density and peculiar velocity fields; {\it (ii)} is highly correlated, at the $\gtrsim 60\,\%$ level, to the line-of-sight projected peculiar velocity field; {\it (iii)} for narrow windows $(σ_z < 0.03$), it is almost completely uncorrelated to the projected galaxy angular density field under the same redshift window; and {\it (iv)} it is largely unaffected by multiplicative and additive systematic errors on the observed number of galaxies that are redshift-independent over $\simσ_z$. We conclude that $δz (\hat{n})$ is a simple and robust tomographic measure of the cosmic density and velocity fields, complementary to angular clustering, that will contribute to more complete exploitations of current and upcoming galaxy redshift surveys.

The $e_g$ orbitals order easier and their ordering explains the $A$-type antiferromagnetic phase in KCuF$_3$ and LaMnO$_3$. In $t_{2g}$ systems the magnetic order changes at a transition from an orbital liquid to orbital ordered states. The fluctuations of $t_{2g}$ orbitals play a prominent role in LaVO$_3$ and YVO$_3$, where they compete with the Jahn-Teller effect and trigger the C-type antiferromagnetic order.

description: This paper uses a nonlinear autoregressive distributed lag framework to assess the role that the exchange rate plays in shaping European agri-food exports after the introduction of Euro. Although the ten countries of this study share the same currency, cross-country discrepancies of exports’ reactions to exchange rate changes are evident. Moreover, exchange rate changes influence exports asymmetrically especially in the long run. Euro appreciations are harmful to a lesser extent than Euro depreciations are beneficial for European agri-food exports. The magnitude of this effect is country-specific and varies considerably between individual exporting countries. Exported quantities are less affected by exchange rate fluctuations than export values.

The latter models the effect of tissue or media resistance to invasion. We found that the existence of tissue intensifies 'Natural Selection' and de-accelerating 'Genetic Drift', both to a limited extent. More interestingly, our results show that short-range migration can eliminate Genetic demixing and conceal Natural Selection.

description: Fluctuations of the soft X-ray background are investigated using harmonic analysis. A section of the ROSAT All-Sky Survey around the north galactic pole is used. The flux distribution is expanded into a set of harmonic functions and the power spectrum is determined. Several subsamples of the RASS have been used and the spectra for different regions and energies are presented. The effects of the data binning in pixels are assessed and taken into account. The spectra of the analyzed samples reflect both small scale effects generated by strong discrete sources and the large scale gradients of the XRB distribution. Our results show that the power spectrum technique can be effectively used to investigate anisotropy of the XRB at various scales. This statistics will become a useful tool in the investigation of various XRB components.

description: The importance of competition between rural and urban uses for water will likely increase, especially in developing countries. We examine residential water demand in the context of a developing country facing the potential climate change effects, with significant changes in incomes, household size, poverty rates and levels of urbanization. Using Chilean municipal-level panel data (1998-2010), we estimate price and income elasticities, and the water-demand response to climate and socio-demographic variables. Impacts of variation in season averages of precipitation and temperature are statistically significant, but only the variation of seasonal average temperature, the temperature deviations about seasonal averages, and the average seasonal rainfall in northern Chile appear to be of practical, economic significance. More urbanized localities have higher per-household water use and reduced sensitivity to temperature variations. Projected water use on average would increase due to climate changes, but by small amounts in the order of one to two percent.

Одним з головних завдань сучасної дошкільної освіти є забезпечення різнобічного гармонійного розвитку особистості. Виникає питання перед педагогічними працівниками закладів дошкільної освіти – як навчити дітей життєвої мудрості, не зашкодивши їхнім тендітним душам? Як виховати їх розумними, упевненими у собі, творчими, чесними, кмітливими, працьовитими й добрими. Як розкрити те найліпше, що є в їхній природі?

description: We present the concept of H-COUP_ver 2, which evaluates the decay rates (including higher order corrections) for the Higgs boson with a mass of 125 GeV in various extended Higgs models. In the previous version (H-COUP_1.0), only a full set of the Higgs boson vertices are evaluated at one-loop level in a gauge invariant manner in these models. H-COUP_ver 2 contains all the functions of H-COUP_1.0. After shortly introducing these extended Higgs models and discussing their theoretical and experimental constraints, we summarize formulae for the renormalized vertices and the decay rates. We then explain how to install and run H-COUP_ver 2 with some numerical examples.

description: Rice is the first strategic product in West Africa since 2008 crisis. To create a customs union, ECOWAS has adopted in October 2013 the final structure of its Common External Tariff (CET). This CET established a fifth band of 35% but taxes milled rice at 10% and will come into force on January, 2015. As the adoption of this CET will have significant effects on the rice sector, it is necessary to assess its potential ex-ante impact on this sector within the region. The results obtained using a GCE model show that this CET will have various effects on the regional rice economies. Urban poverty was more pronounced than rural poverty and intra-regional trade experienced a remarkable increase. The negatives effects of the CET are more pronounced in Nigeria and Guinea. Therefore, the current version of the CET will have rather mixed effects if support measures are not implemented.

description: The cheese processing aid is used in Switzerland since 1999 to support cheese production and raw milk producer. This paper presents ex-post and ex-ante evaluations of reductions of this processing aid. The ex-post analysis, using vector autoregressive models and monthly milk prices, estimates the effects of reductions of the aid on milk prices for Emmentaler, Gruyère and industrial cheese production. Declines in the aid were found to have significant negative but heterogeneous effects on milk prices and that these reductions are transmitted only imperfectly. The ex-ante analysis evaluates the effects of a complete removal of the aid using a partial equilibrium model. Despite the contraction of cheese production, this was found to have a positive net global welfare impact due to the reallocation of raw milk to other milk channels.

description: Many aspects have to be considered concerning the digital economy. Work through online platforms is increasingly stronger in the current global scenario. One of these types of work is known as Microtasking crowdsourcing. These platforms rely on Artificial Intelligence (AI), which provides full support for it. Task assignment and task recommendation are applications of this intelligence. Even though AI has proven to be an ally for this type of work, some ethical aspects emerge from this and have to be studied. The general objective of this thesis is to study the ethical judgment of individuals regarding the use of AI in these online platforms. For this purpose, a hypothetical scenario about Microtasking crowdsourcing through online platforms where there is a working relationship with AI, was created. For this, the Multidimensional Ethics Scale (MES) developed by Reidenbach and Robin (1990) was chosen, and a survey was applied (N=118). Results showed that participants tended to judge as unethical as per the (i) Moral Equity and (ii) Relativistic dimensions. For (iii) Contractualism, the individuals perceived as ethical. Furthermore, significant correlation (p-value = 0.022) was found between people’s fear of computers and the perception of an unwritten contract being violated. The respondents also differ in their perception of an unspoken promise being violated (p-value = 0.033) and an unwritten contract being violated (p-value = 0.005) among their level of education. The participants' perception of justice (p-value = 0.019) and fairness (p-value = 0.026) diverge according to their company roles.

INVESTIGATIONS ON INSTABILITY OF PERIODIC ORBITS OF NIGCOMSAT AROUND TRIANGULAR LAGRANGIAN POINTS IN THE EARTH-MOON SYSTEM WITH RADIATION PRESSURE AND VARIABLE MASSES

description: The Nigerian Space Agency launched the Nigerian Communication Satellites (NigComSat) into orbit in 2007. The satellite was designed to have a lifespan of 15 years and to remain in orbit for that duration. Unfortunately, after a year, the orbit became unstable and the satellite left orbit. In this paper, the focus is to investigate instability of the periodic orbits of the NigComSat around triangular Lagrangian points (TLPs) using the model of the restricted three-body problem with radiation pressure and variable masses. The masses of the host bodies are assumed to vary with time and the smaller bodyisa radiation emitter. We compute explicit expressions for the frequency, angle of rotation of the principal axis, eccentricity and lengths of semi-axes of the orbits of the satellite. Since some facts are not directly discernable from the analytic solutions, numerical evidences are provided to analyze the structure of the orbits, when the host bodies are assumed to be the Earth and Moon. Our numerical explorations reveal that due to the mass variation parameter, the orientation and paths around the TLPs differ and at some points, the NigComSat travels around the Earth and TLP while for some value of the mass variation parameter, the NigComSat does not travel around the TLP and the Earth. Further, as the mass variation increases the orbit flattens and the NigComSat leaves orbit. Further, the zero velocity curves around TLPs are explored and it is seen that the most significant perturbing effect is the mass variation of the main bodies. Additionally, when the Earth and Moon gain sufficient mass, large region becomes dynamically forbidden for the NigComSat and it leaves the vicinity of the TLPs and escape into space. Consequently, the NigComSat leaves the orbits due to the instabilities posed by the increasing mass of the Earth and the Moon coupled with the radiation pressure of the Moon. The orbits about Lagrangian points are important for scientific investigations. Since, a number of space missions have been completed and some are being proposed by various space agencies.

description: This article describes the various experimental bounds on the variation of the fundamental constants of nature. After a discussion on the role of fundamental constants, of their definition and link with metrology, the various constraints on the variation of the fine structure constant, the gravitational, weak and strong interactions couplings and the electron to proton mass ratio are reviewed. This review aims (1) to provide the basics of each measurement, (2) to show as clearly as possible why it constrains a given constant and (3) to point out the underlying hypotheses. Such an investigation is of importance to compare the different results, particularly in view of understanding the recent claims of the detections of a variation of the fine structure constant and of the electron to proton mass ratio in quasar absorption spectra. The theoretical models leading to the prediction of such variation are also reviewed, including Kaluza-Klein theories, string theories and other alternative theories and cosmological implications of these results are discussed. The links with the tests of general relativity are emphasized.

description: VFEL lasing in system with dynamical undulator is described. In this system radiation of long wavelength creates the undulator for lasing on shorter wavelength. Two diffraction gratings with different spatial periods form VFEL resonator. The grating with longer period pumps the resonator with long wavelength radiation to provide necessary amplitude of undulator field. The grating with shorter period makes mode selection for short wavelength radiation. Lasing of such a system in terahertz frequency range is discussed.

description: The fundamental concepts of Riemannian geometry, such as differential forms, vielbein, metric, connection, torsion and curvature, are generalized in the context of non-commutative geometry. This allows us to construct the Einstein-Hilbert-Cartan terms, in addition to the bosonic and fermionic ones in the Lagrangian of an action functional on non-commutative spaces. As an example, and also as a prelude to the Standard Model that includes gravitational interactions, we present a model of chiral spinor fields on a curved two-sheeted space-time with two distinct abelian gauge fields. In this model, the full spectrum of the generalized metric consists of pairs of tensor, vector and scalar fields. They are coupled to the chiral fermions and the gauge fields leading to possible parity violation effects triggered by gravity.
