description: The ability of water to form cage-like structures and capture gas molecules under high pressure and low temperatures lead to problems in gas pipelines, especially in the mid-20th century. Also, there is an enormous amount of this so-called gas hydrate, captured in deep sea sediments or in terrestrial permafrost soils in which they reserve a possible degradable energy resource. On the other hand, they also maintain a high risk to enhance the ongoing climate change. At the same time, through their high energy storage ability, gas hydrates exhibit a high potential for industrial applications like alternative energy storage, carbon capture technologies or cleaning of exhaust emissions through separation and storage. But through their complex kinetics and ongoing dynamics through induction, synthesis and dissociation, the usage of hydrates is still far away from relevant industrial application. To make the potential capable there is still a huge amount of basic research necessary: Specially to shorten the induction time. An earlier thesis at FH-Vorarlberg exposed a potential method to shorten the induction time through a stirred reactor with an extremely high stirring rate without the usage of promotors. Therefore, this thesis is dedicated to expose the possible reasons for the witnessed effect through high stirring rates (>10000 rpm) at different pressure and tempera-ture conditions. The goal is to show possible physical effects to shorten the induction time of hy-drate synthesis. Therefore, a stirred reactor is used in which the possible effects should be investi-gated through the research with CO2 hydrates. In the research, there will be a closer look on phe-nomena like cavitation, increasing the phase interface through stirring or pressure fluctuations. The results of this thesis show an interesting connection between pressure, stirring rate and increased phase interface. Furthermore, there are also some exposed significances between stirring under spe-cial conditions which were exposed through statistical analyses. The results show that stirring could possibly be a new driving force when executed under the right conditions.

description: Presentation 'Visualization of missing data and imputations in time series' at useR! Conference 2020. Abstract: When working with time series, missing data is an all too common problem. Especially when dealing with sensor data, all kind of sources of error(data recording, data transmission, data processing) can lead to missing values. These missing values quite often complicate later processing and analysis steps. Missing data visualization is the logical first step when encountering these problems. Visualizing the patterns in the missing data can provide information about the reasons for the missing values and give hints on how to best proceed with the analysis. In case it is decided to replace (impute) the missing values, visualizations are a useful tool to assess the imputation quality. This talk gives a short intro to the new/updated missing data plotting functions being introduced with the 3.1 version of the imputeTS CRAN package - while also mentioning useful functions from further CRAN packages.

description: After 63 year of Independence and a population of one billion, India is the largest democracy in the world. To sustain this democracy and freedom, it is very necessary to ensure economic empowerment and better quality of life for all the citizens of India. Since the real India lives in villages, the rural development has assumed high priority and it is one of the very important factors of the Indian economy. The Industrial Policy Resolution in 1956 gave the public sector enterprises a strategic role in Indian Economy and the public sector was thought of as the engine for self-reliant economic growth to develop a sound agricultural and industrial base, diversify the economy and overcome economic and social backwardness. In this paper, we shall address the trade-off between the social and economic objectives of public sector enterprises with a focus on the Neyveli Lignite Corporation (NLC) and its role in the community development and social welfare of Neyveli population.

description: Confinement of single ions in a novel radio-frequency (RF) quadrupole ion trap with spherical shape is investigated. An optimization of this spherical ion trap (SIT) is carried out in order to suppress its nonlinearity substantially by eliminating the electric octupole moment. Hence, a trapping potential and consequently an electric field very similar to the ideal quadrupole ion trap (QIT) are obtained. Afterwards, three stability regions for the optimized SIT are numerically computed. The regions coincide well with those reported in the literature for the ideal QIT. The reason is attributed to the zero electric octupole moment of our proposed trap. The SIT simple geometry and relative ease of fabrication along with its increased trapping volume compared to the conventional hyperbolic quadrupole ion trap, make it an appropriate choice for miniaturization.

description: First, we cannot expect to explore the paths of social explanation or political evaluation without having an overview of people and society: without having an indicative portrait of the nature of individuals and the differences that life social causes in them. Second, we cannot have a global view of people and society if we do not have a drawing of their psychological constitution, a portrait of what it is like to be psychologically equipped as human beings. This involves making social and political theory based on social ontology based on the theory of mind and society. And this also means dealing with the philosophical psychology of the theory of mind as such.

description: Trapping ultracold atoms in optical lattices enabled numerous breakthroughs uniting several disciplines. Coupling these systems to quantized light leads to a plethora of new phenomena and has opened up a new field of study. Here we introduce a physically novel source of competition in a many-body strongly correlated system: We prove that quantum backaction of global measurement is able to efficiently compete with intrinsic short-range dynamics of an atomic system. The competition becomes possible due to the ability to change the spatial profile of a global measurement at a microscopic scale comparable to the lattice period without the need of single site addressing. In coherence with a general physical concept, where new competitions typically lead to new phenomena, we demonstrate novel nontrivial dynamical effects such as large-scale multimode oscillations, long-range entanglement and correlated tunneling, as well as selective suppression and enhancement of dynamical processes beyond the projective limit of the quantum Zeno effect. We demonstrate both the break-up and protection of strongly interacting fermion pairs by measurement. Such a quantum optical approach introduces into many-body physics novel processes, objects, and methods of quantum engineering, including the design of many-body entangled environments for open systems.

description: The astrophysics community is considering plans for a variety of gamma-ray telescopes (including ACT and GRIPS) in the energy range 1--100 MeV, which can fill in the so-called "MeV gap" in current sensitivity. We investigate the utility of such detectors for the study of low-mass dark matter annihilation or decay. For annihilating (decaying) dark matter with a mass below about 140 MeV (280 MeV) and couplings to first generation quarks, the final states will be dominated by photons or neutral pions, producing striking signals in gamma-ray telescopes. We determine the sensitivity of future detectors to the kinematically allowed final states. In particular, we find that planned detectors can improve on current sensitivity to this class of models by up to a few orders of magnitude.

Near-IR Spectroscopic Monitoring of Class I Protostars: Variability of Accretion and Wind Indicators

Year: 2014
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: We present the results of a program that monitored the near-IR spectroscopic variability of a sample of 19 embedded protostars. Spectra were taken on time intervals from 2 days to 3 years, over a wavelength range from 0.85 μm to 2.45 μm, for 4-9 epochs of observations per target. We found that the spectra of all targets are variable, and that every emission feature observed is also variable (although not for all targets). With one exception, there were no drastic changes in the continua of the spectra, nor did any line completely disappear, nor did any line appear that was not previously apparent. This analysis focuses on understanding the connection between accretion (traced by H Br $γ$ and CO) and the wind (traced by He I, [FeII], and sometimes H$_2$). For both accretion and wind tracers, the median variability was constant versus time interval between observations, however the maximum variability that we observed increased with time interval between observations. Extinction is observed to vary within the minimum sampling time of 2 days, suggesting extinguishing material within a few stellar radii at high disk latitudes. The variability of [FeII] and H$_2$ were correlated for most (but not all) of the 7 YSOs showing both features, and the amplitude of the variability depends on the veiling. Although the occurrence of CO and Br $γ$ emission are connected, their variability is uncorrelated, suggesting that these emissions originate in separate regions near the protostar (e.g., disk and wind).

description: The study of a quasi back-to-back isolated pair made of a heavy quarkonium, such as a J/psi or a Upsilon, and a photon produced in proton-proton collisions at the LHC, is probably the optimal way to get right away a first experimental determination of two gluon transverse-momentum-dependent distributions (TMDs) in an unpolarized proton, f1^g and h1^perp,g the latter giving the distribution of linearly polarized gluons. To substantiate this, we calculate the transverse-momentum-dependent effects that arise in the process under study and discuss the feasibility of their measurements.

description: We show that the experimental data on $|V_{ub}|$ in various $B$ meson decay modes suggest a possibility of $CP$-violating right-handed current in the $b\to u$ transition. Its consequences in $B\toππ,\,ρρ,\,DK$ are examined and compared with experimental results in order to clarify possible signals of the $CP$ violation in these decay modes. As a result, we find that the $CP$-violating right-handed current is consistent with current experimental data. Its signal might be discovered by precise $CP$ measurements in future experiments.

Optimal algorithms for universal random number generation from finite memory sources

description: We study random number generators (RNGs), both in the fixed to variable-length (FVR) and the variable to fixed-length (VFR) regimes, in a universal setting in which the input is a finite memory source of arbitrary order and unknown parameters, with arbitrary input and output (finite) alphabet sizes. Applying the method of types, we characterize essentially unique optimal universal RNGs that maximize the expected output (respectively, minimize the expected input) length in the FVR (respectively, VFR) case. For the FVR case, the RNG studied is a generalization of Elias's scheme, while in the VFR case the general scheme is new. We precisely characterize, up to an additive constant, the corresponding expected lengths, which include second-order terms similar to those encountered in universal data compression and universal simulation. Furthermore, in the FVR case, we consider also a "twice-universal" setting, in which the Markov order k of the input source is also unknown.

description: With the completion of the Planck mission, in order to continue to gather cosmological information it has become crucial to understand the Large Scale Structures (LSS) of the universe to percent accuracy. The Effective Field Theory of LSS (EFTofLSS) is a novel theoretical framework that aims to develop an analytic understanding of LSS at long distances, where inhomogeneities are small. We further develop the description of biased tracers in the EFTofLSS to account for the effect of baryonic physics and primordial non-Gaussianities, finding that new bias coefficients are required. Then, restricting to dark matter with Gaussian initial conditions, we describe the prediction of the EFTofLSS for the one-loop halo-halo and halo-matter two-point functions, and for the tree-level halo-halo-halo, matter-halo-halo and matter-matter-halo three-point functions. Several new bias coefficients are needed in the EFTofLSS, even though their contribution at a given order can be degenerate and the same parameters contribute to multiple observables. We develop a method to reduce the number of biases to an irreducible basis, and find that, at the order at which we work, seven bias parameters are enough to describe this extremely rich set of statistics. We then compare with the output of $N$-body simulations. For the lowest mass bin, we find percent level agreement up to $k\simeq 0.3\,h\,{\rm Mpc}^{-1}$ for the one-loop two-point functions, and up to $k\simeq 0.15\,h\,{\rm Mpc}^{-1}$ for the tree-level three-point functions, with the $k$-reach decreasing with higher mass bins. This is consistent with the theoretical estimates, and suggests that the cosmological information in LSS amenable to analytical control is much more than previously believed.

description: Fundamental physical phenomena such as laser-induced ionization, driven quantum tunneling, Faraday waves, Bogoliubov quasiparticle excitations, and the control of new states of matter rely on time-periodic driving of the system. A remarkable property of such driving is that it can induce the localized (bound) states to resonantly couple to the continuum. Therefore experiments that allow for enlightening and controlling the mechanisms underlying such coupling are of paramount importance. We implement such an experiment in a special fiber optics system characterized by a dispersion oscillating along the propagation coordinate, which mimics "time". The quasi-momentum associated with such periodic perturbation is responsible for the efficient coupling of energy from the localized wave-packets sustained by the fiber nonlinearity into free-running linear dispersive waves (continuum), at multiple resonant frequencies. Remarkably, the observed resonances can be explained by means of a unified approach, regardless of the fact that the localized state is a soliton-like pulse or a shock front.

description: We study the thermal relaxation dynamics of VO$_2$ films after the ultrafast photo-induced metal-insulator transition for two VO$_2$ film samples grown on Al$_2$O$_3$ and TiO$_2$ substrates. We find two orders of magnitude difference in the recovery time (a few ns for the VO$_2$/Al$_2$O$_3$ sample vs. hundreds of ns for the VO$_2$/TiO$_2$ sample). We present a theoretical model that accurately describes the MIT thermal properties and interpret the experimental measurements. We obtain quantitative results that show how the microstructure of the VO$_2$ film and the thermal conductivity of the interface between the VO$_2$ film and the substrate affect long time-scale recovery dynamics. We also obtain a simple analytic relationship between the recovery time-scale and some of the film parameters.

description: The structural properties of Thallium (III) oxide (Tl2O3) have been studied both experimentally and theoretically under compression at room temperature. X-ray powder diffraction measurements up to 37.7 GPa have been complemented with ab initio total-energy calculations. The equation of state of Tl2O3 has been determined and compared to related compounds. It has been found experimentally that Tl2O3 remains in its initial cubic bixbyite-type structure up to 22.0 GPa. At this pressure, the onset of amorphization is observed, being the sample fully amorphous at 25.2 GPa. The sample retains the amorphous state after pressure release. To understand the pressure-induced amorphization process, we have studied theoretically the possible high-pressure phases of Tl2O3. Although a phase transition is predicted at 5.8 GPa to the orthorhombic Rh2O3-II-type structure and at 24.2 GPa to the orthorhombic a-Gd2S3-type structure, neither of these phases were observed experimentally, probably due to the hindrance of the pressure-driven phase transitions at room temperature. The theoretical study of the elastic behavior of the cubic bixbyite-type structure at high-pressure shows that amorphization above 22 GPa at room temperature might be caused by the mechanical instability of the cubic bixbyite-type structure which is theoretically predicted above 23.5 GPa.

description: Archaeological investigations were conducted by the Office of Public Archaeology at sites Sba-534 and Sba-680 in March, 1981, to mitigate impacts resulting from the construction of STS 69 KV Transmission Line on Vandenberg Air Force Base, California. Excavations in peripheral areas of both sites yielded chipped stone assemblages consisting primarily of chert debitage. Preliminary analysis of these materials suggests that the sites served in part as loci for the maintenance and modification of chipped stone tools. The vertical patterning noted in the cultural deposits is probably the result of episodic deflation of the dunes in which the sites are located. It is recommended that the full study of the collections, to be completed as part of the forthcoming analysis of all STS-related mitigation programs, incorporate a systematic analysis of wind polish on artifacts to test the deflation hypothesis, and a detailed examination of lithic debitage characteristics to assess site function.

description: We adopt an isotropic representation of the Fourier-transformed two-point correlation tensor of the magnetic field to estimate the magnetic energy and helicity spectra as well as current helicity spectra of two individual active regions (NOAA 11158 and NOAA 11515) and the change of the spectral indices during their development as well as during the solar cycle. The departure of the spectral indices of magnetic energy and current helicity from 5/3 are analyzed, and it is found that it is lower than the spectral index of the magnetic energy spectrum. Furthermore, the fractional magnetic helicity tends to increase when the scale of the energy-carrying magnetic structures increases. The magnetic helicity of NOAA 11515 violates the expected hemispheric sign rule, which is interpreted as an effect of enhanced field strengths at scales larger than 30-60Mm with opposite signs of helicity. This is consistent with the general cycle dependence, which shows that around the solar maximum the magnetic energy and helicity spectra are steeper, emphasizing the large-scale field.

description: Purpose: We aim with this report to provide information on how the Covid-19 pandemic affected education and citizenship education in Turkey. Design: The report is based on literature review, the analysis of social media, and the observations of the authors. We provide a general framework of Turkish education after the pandemic using sources such as official statements from government offices; social media entries were analyzed to provide different perspectives. Finally, observations of the authors based on their experiences with distance learning were included in the report. Findings: We argue that despite the efforts of the state, there are still problems in the distance learning process, mainly relating to the access to online classes and the very limited room given to Covid-19 as a topic in social studies courses. In addition, we find that social media have played a significant role in increasing citizen participation as a consequence of the pandemic

A Framework for General Sparse Matrix-Matrix Multiplication on GPUs and Heterogeneous Processors

description: General sparse matrix-matrix multiplication (SpGEMM) is a fundamental building block for numerous applications such as algebraic multigrid method (AMG), breadth first search and shortest path problem. Compared to other sparse BLAS routines, an efficient parallel SpGEMM implementation has to handle extra irregularity from three aspects: (1) the number of nonzero entries in the resulting sparse matrix is unknown in advance, (2) very expensive parallel insert operations at random positions in the resulting sparse matrix dominate the execution time, and (3) load balancing must account for sparse data in both input matrices. In this work we propose a framework for SpGEMM on GPUs and emerging CPU-GPU heterogeneous processors. This framework particularly focuses on the above three problems. Memory pre-allocation for the resulting matrix is organized by a hybrid method that saves a large amount of global memory space and efficiently utilizes the very limited on-chip scratchpad memory. Parallel insert operations of the nonzero entries are implemented through the GPU merge path algorithm that is experimentally found to be the fastest GPU merge approach. Load balancing builds on the number of necessary arithmetic operations on the nonzero entries and is guaranteed in all stages. Compared with the state-of-the-art CPU and GPU SpGEMM methods, our approach delivers excellent absolute performance and relative speedups on various benchmarks multiplying matrices with diverse sparsity structures. Furthermore, on heterogeneous processors, our SpGEMM approach achieves higher throughput by using re-allocatable shared virtual memory.

Exploring teaching and learning about the Corona crisis in social studies webinars
Creators: name: Torrau, Jens Soeren
Publisher: name: JSSE - Journal of Social Science Education
Year: 2020

description: Purpose: Due to the Corona pandemic in 2020 schools needed to handle a challenging situation: They needed to find solutions to the question how lessons can proceed in times of physical distancing. This stages a broader need to reflect on how learning processes are organized with digital media. Thus, insights into concrete teaching and learning interactions can help to better understand lesson designs in virtual classrooms from a didactic perspective. Methodology: This article aims to document a webinar of a German 9th grade class in its moments relevant to social studies teaching. Thus, this paper provides insights into an explorative case study that uses recordings and classroom observations. In order to analyze knowledge processes in digital contexts didactically, the “Wissensdidaktische Hermeneutik” serves as a qualitative research method. Findings: The documented sequences of the webinar that deals with the recent media coverage of Corona show that the webinar takes into account both the learning needs of the students and an urgent social studies topic. Therefore, the social studies teacher uses advance organizers through her own explanations so that all students can stay on the same page. Furthermore, she introduces elements of the Flipped Classroom that display implications for social interaction in social studies webinars – particularly for the speech act “to explain”.
