description: Data security and data protection are a key concern in the digital age, especially with increasing reliance on cloud computing and distributed computing environments. It protects data in storage and transmission with traditional security measures such as idle encryption and in transit. However, data must be decrypted in memory and suspended potential threats such as unauthorized access, malware, and insider attacks, so it remains vulnerable during processing. Confidential computers deal with this challenge by enabling calculations on data encrypted in a trusted execution environment (TEA) and ensure that sensitive information remains protected during processing. Large technology providers, including Intel SGX, AMD SEV and ARM, have developed hardware-based T-shirts that make sensitive computers easier. This paradigm improves data security for a variety of applications, including secure cloud computing, financial transactions, health data processing, and AI model training for sensitive data records. Additionally, we discuss challenges associated with its deployment, such as performance, limited developer accessibility, and the complexity of integration with existing cloud infrastructures. As the demand for data protection management technology continues to grow, the development of confidential computers is expected to play a key role in futuredesigns of secure data processing.
Nonlinear light-Higgs coupling in superconductors beyond BCS: Effects of the retarded phonon-mediated interaction

description: We study the contribution of the Higgs amplitude mode on the nonlinear optical response of superconductors beyond the BCS approximation by taking into account the retardation effect in the phonon-mediated attractive interaction. To evaluate the vertex correction in nonlinear optical susceptibilities that contains the effect of collective modes, we propose an efficient scheme which we call the "dotted DMFT" based on the nonequilibrium dynamical mean-field theory (nonequilibrium DMFT) to go around the difficulty of solving the Bethe-Salpeter equation and analytical continuation. The vertex correction is represented by the derivative of the self-energy with respect to the external driving field, which is self-consistently determined by the differentiated ("dotted") DMFT equations. We apply the method to the Holstein model, a prototypical electron-phonon-coupled system, to calculate the susceptibility for the third-harmonic generation including the vertex correction. The results show that, in sharp contrast to the BCS theory, the Higgs mode can contribute to the third-harmonic generation for general polarization of the laser field with an order of magnitude comparable to the contribution from the pair breaking or charge density fluctuations. The physical origin is traced back to the nonlinear resonant light-Higgs coupling, which has been absent in the BCS approximation.
The impact of relative energy price differences on markups
Creators: name: Ammer, Joseph
Publisher: name: University of Chicago
Year: 2022

description: This paper examines whether rising relative energy costs among foreign competitors lead to higher domestic markups. I follow prior environmental and trade literature by using energy prices as a proxy for environmental stringency. The hypothesis is built upon and motivated by the theoretical model in Baccianti & Schenker (2021) which shows that carbon leakage to firms with a comparative cost advantage might be captured through increases in markups by such firms. I estimate markups with the DeLoecker and Warczynski (2012) approach and find only little impact of energy price differences on markups. On a large financial dataset from AMADEUS, simple fixedeffect regression results hover around a domestic 1% markup increase in response to a one standard deviation increase in energy prices among foreign competitors. The effect diminishes and becomes statistically insignificanct once accounting for endogeneity concerns with a 2SLS and Blundell-Bond estimator.

description: We apply the background field technique, recently developed for a general class of nonlinear symmetries, at tree level, to the Volkov-Akulov theory with spontaneously broken N=1 supersymmetry. We find that the background field expansion in terms of the free fields to the lowest order reproduces the nonlinear supersymmetry transformation rules. The double soft limit of the background field is, in agreement with the new general identities, defined by the algebra of the nonlinear symmetries.

Welche Potenziale zur Elternstärkung bieten Eltern-Kind-Gruppen? Dieser Frage wird am Beispiel der Gruppe von Eltern und Kindern mit Down-Syndrom bei der stiftungNETZ nachgegangen. An der Gruppe nehmen sechs Mütter mit ihren Kindern teil. Mit vier Elternpaaren wurde ein qualitatives Interview durchgeführt. Die kategorienbasierte Auswertung zeigt, dass die leitenden Früherzieherinnen eine wichtige Funktion haben. Sie betreuen die Kinder und stehen für Fragen der Mütter zur Verfügung. Dies gibt den Müttern Entlastung und Bestätigung, ermöglicht ihnen Erfahrungsaustausch und Vernetzung. Die Unterstützung durch diese Gruppe hat eine nachhaltige Wirkung auch auf die ganze Familie, was zur Stärkung ihres Kohärenzgefühls und ihrer Resilienz beiträgt.

description: Dynamics in the throat of rapidly rotating Kerr black holes is governed by an emergent near-horizon conformal symmetry. The throat contains unstable circular orbits at radii extending from the ISCO down to the light ring. We show that they are related by conformal transformations to physical plunges and osculating trajectories. These orbits have angular momentum arbitrarily higher than that of ISCO. Using the conformal symmetry we compute analytically the radiation produced by the physical orbits. We also present a simple formula for the full self-force on such trajectories in terms of the self-force on circular orbits.

description: We report the discovery of K2-98 b (EPIC 211391664 b), a transiting Neptune-sized planet monitored by the K2 mission during its campaign 5. We combine the K2 time-series data with ground-based photometric and spectroscopic follow-up observations to confirm the planetary nature of the object and derive its mass, radius, and orbital parameters. K2-98 b is a warm Neptune-like planet in a 10-day orbit around a V=12.2~mag F-type star with $M_\star$=$ 1.074\pm0.042$, $R_\star$=$ 1.311 ^{+ 0.083} _{ - 0.048} $, and age of $5.2_{-1.0}^{+1.2}$~Gyr. We derive a planetary mass and radius of $M_\mathrm{p}$=$ 32.2 \pm 8.1 $ and $R_\mathrm{p}$=$4.3^{+0.3}_{-0.2}$. K2-98 b joins the relatively small group of Neptune-sized planets whose both mass and radius have been derived with a precision better than 25 %. We estimate that the planet will be engulfed by its host star in $\sim$3~Gyr, due to the evolution of the latter towards the red giant branch.

description: Dark matter detectors that utilize liquid xenon have now achieved tonne-scale targets, giving them sensitivity to all flavours of supernova neutrinos via coherent elastic neutrino-nucleus scattering. Considering for the first time a realistic detector model, we simulate the expected supernova neutrino signal for different progenitor masses and nuclear equations of state in existing and upcoming dual-phase liquid xenon experiments. We show that the proportional scintillation signal (S2) of a dual-phase detector allows for a clear observation of the neutrino signal and guarantees a particularly low energy threshold, while the backgrounds are rendered negligible during the supernova burst. XENON1T (XENONnT and LZ; DARWIN) experiments will be sensitive to a supernova burst up to 25 (35; 65) kpc from Earth at a significance of more than 5 sigma, observing approximately 35 (123; 704) events from a 27 Msun supernova progenitor at 10 kpc. Moreover, it will be possible to measure the average neutrino energy of all flavours, to constrain the total explosion energy, and to reconstruct the supernova neutrino light curve. Our results suggest that a large xenon detector such as DARWIN will be competitive with dedicated neutrino telescopes, while providing complementary information that is not otherwise accessible.

description: Exciton-polaritons are light-matter quasi-particles, the theoretical concept of which was developed in the 1950s, and intensely studied in the following decades in bulk material. The observation of strong coupling between photons and excitons in semiconductor microcavities in 1992 paved the way for promising concepts for applications such as quantum simulators, optical logic circuits and novel light emitting devices. However, the realization of devices based on exciton-polaritons is still in the proof of principle stage. In this thesis, new insights into the fundamental optical properties of exciton-polaritons as well as a contribution towards the realization of polariton-based lasing devices and logic circuits are provided. Here, exciton-polaritons in Cu2O bulk semiconductor material and in GaAs-based microcavities are examined. In Cu2O the up to now hardly investigated blue exciton-polariton series is studied by means of a novel spectroscopic approach involving two single-frequency lasers, which gives evidence for a coherent propagation of polaritons in a spectral region of large absorption. Furthermore, the feasibility of different concepts of polariton laser operation in GaAs-based microcavities is evaluated, in which the regime of polariton lasing in the visible spectral range up to temperatures of 70 K is identified, whereas no indication for terahertz lasing is observed. Finally, the interactions between polariton condensates and background carriers are investigated. Here, a pronounced decrease of the polariton condensate coherence is observed due to the presence of background carriers. Beyond that, an all-optical approach for steering the polariton condensate flow by tailoring potential landscapes by means of injection of background carriers is presented, which is appealing for the realization of all-optical logic circuits.

Microscopic theory of the Coulomb based exchange coupling in magnetic tunnel junctions

Publisher: name: arXiv

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We study interlayer exchange coupling (IEC) based on the many-body Coulomb interaction between conduction electrons in magnetic tunnel junction (MTJ). This mechanism complements the known IEC based on virtual electron hopping (or spin currents). We find that these two mechanisms have different behavior on system parameters. The Coulomb based IEC may exceed the hopping based exchange coupling. We show that the Coulomb based exchange coupling, in contrast to the hopping based coupling, depends strongly on the dielectric constant of the insulating layer. The dependence of the IEC on the dielectric properties of the insulating layer in MTJ is similar to magneto-electric (ME) effect where electric and magnetic degrees of freedom are coupled. We calculate the IEC as a function of temperature and electric field for MTJ with ferroelectric (FE) layer and show that IEC has a sharp decrease in the vicinity of the FE phase transition and varies strongly with external electric field.

Industrial Waste and Urban Communities in Addis Ababa: the Case of Akaki Kaliti And Kolfe Keranio Sub Cities
Creators: name: Kifle, Selamawit

Year: 2008

description: Most industrial establishments in Addis Ababa discharge their wastes into the nearby rivers or on open spaces. The urban communities, who live adjacent to industries, face health problems due to industrial wastes. The study took two sub cities in Addis Ababa region. These are Akaki kaliti and Kolfe Keranio sub cities. In these sub cities the industries which are known by EPA for polluting the environment were selected. From Akaki Kaliti Sub city: Akrem Metena Animal Feed Factory, Kaliti Food SC, Akaki Metal Products Factory and K.K Textile Factory and from Kolfe Keranio Addis Ababa Tannery and Gulelle Soap Factory were selected.The general objective of the research is to assess the extent of the industrial waste problem on urban communities. Literature states that the proximity to the source of waste generation increases the risk of being affected by industrial wastes. The findings of the research revealed that all the industries use industrial waste disposal systems, more specifically open and ocean dumping. Recycling or waste treatment systems are used by 33 percent of the industries. No industry uses waste avoidance or reduction methods. The licensing and registering bodies including Ministry of Trade and Industry at different levels and Ethiopian Investment Agency do not have siting criteria applicable in the placement of industries. Environmental Protection offices are not actively involved in controlling and regulating the industries which are polluting the environment due to industrial wastes. Ministry of Health did very little with respect to industrial wastes. On the other hand, the communities are affected by the industrial waste problem. Most respondents have respiratory diseases, cough, diarrhea, and eye problems. The day-to-day lives of the community are affected by pollution as a result of industrial wastes. The community had put complaints to different bodies including the sub city's top management, the sub city's Environmental Protection offices, the kebeles & industries. To solve the industrial waste problem, coordinated effort of all involved is required. Awareness creation task should be done by Environmental Protection Authority and Ministry of Health. Siting criteria needs to be designed and implemented. Measures should be taken on those industries disposing untreated wastes on open spaces and/or water bodies. Coordinated effort would only work if those involved are aware of the problems and the solutions suggested

description: We propose to use spin hydrodynamics, a two-fluid model of spin propagation, as a generalization of the diffusion equation. We show that in the dense limit spin hydrodynamics reduces to Fick's law and the diffusion equation. In the opposite limit spin hydrodynamics is equivalent to a collisionless Boltzmann treatment of spin propagation. Spin hydrodynamics avoids unphysical effects that arise when the diffusion equation is used to describe to a strongly interacting gas with a dilute corona. We apply spin hydrodynamics to the problem of spin diffusion in a trapped atomic gas. We find that the observed spin relaxation rate in the high temperature limit [Sommer et al., Nature 472, 201 (2011)] is consistent with the diffusion constant predicted by kinetic theory.

description: In this paper, an active control policy design for a fractional order (FO) financial system is attempted, considering multiple conflicting objectives. An active control template as a nonlinear state feedback mechanism is developed and the controller gains are chosen within a multi-objective optimization (MOO) framework to satisfy the conditions of asymptotic stability, derived analytically. The MOO gives a set of solutions on the Pareto optimal front for the multiple conflicting objectives that are considered. It is shown that there is a trade-off between the multiple design objectives and a better performance in one objective can only be obtained at the cost of performance deterioration in the other objectives. The multi-objective controller design has been compared using three different MOO techniques viz. Non Dominated Sorting Genetic Algorithm-II (NSGA-II), epsilon variable Multi-Objective Genetic Algorithm (ev-MOGA), and Multi Objective Evolutionary Algorithm with Decomposition (MOEA/D). The robustness of the same control policy designed with the nominal system settings have been investigated also for gradual decrease in the commensurate and incommensurate fractional orders of the financial system.

description: In a periodically driven (Floquet) system, there is the possibility for new phases of matter, not present in stationary systems, protected by discrete time-translation symmetry. This includes topological phases protected in part by time-translation symmetry, as well as phases distinguished by the spontaneous breaking of this symmetry, dubbed "Floquet time crystals". We show that such phases of matter can exist in the pre-thermal regime of periodically-driven systems, which exists generically for sufficiently large drive frequency, thereby eliminating the need for integrability or strong quenched disorder that limited previous constructions. We prove a theorem that states that such a pre-thermal regime persists until times that are nearly exponentially-long in the ratio of certain couplings to the drive frequency. By similar techniques, we can also construct stationary systems which spontaneously break *continuous* time-translation symmetry. We argue furthermore that for driven systems coupled to a cold bath, the pre-thermal regime could potentially persist to infinite time.

description: We have measured Hall effect, magnetotransport and magnetostriction on the field induced phases of single crystalline UPt$_2$Si$_2$ in magnetic fields up to 60\,T at temperatures down to 50\,mK. For the magnetic field applied along the $c$ axis we observe strong changes in the Hall effect at the phase boundaries. From a comparison to band structure calculations utilizing the concept of a dual nature of the uranium 5$f$ electrons, we find evidence for field induced topological changes of the Fermi surface due to at least one Lifshitz transition. Furthermore, we find a unique history dependence of the magnetotransport and magnetostriction data, indicating that the Lifshitz type transition is of a discontinuous nature, as predicted for interacting electron systems.

Rotational motion in the molecular crystals meta- and ortho-carborane studied by deuteron nuclear magnetic resonance

description: Spin-lattice and spin-spin-relaxation times, one- and two-dimensional spectra as well as two- and four-time correlation functions were measured for the molecular crystals ortho- and meta-carborane using deuteron nuclear magnetic resonance. It is found that in their noncubic phases these crystals exhibit highly anisotropic motions. In order to allow for a quantitative description of the motional geometry of the carboranes several stochastic models are formulated. By comparison of the model calculations with the experimental results it is found that the dynamics of these quasi-icosahedrally shaped molecules is governed by a composite reorientation process. Here the molecules perform threefold jumps around a molecule-fixed axis which itself can be tilted in four different directions with respect to a crystal-fixed axis. The tilt angle increases significantly with increasing temperature. On the basis of measurements of four-time stimulated-echo functions, implications for dynamic heterogeneity also in comparison with that of supercooled liquids are discussed.
Assessment of Ethiopian Pastoral Development Approach and Its Impact on the Livelihood of households in Ewa Woreda of Afar Regional State
Creators: name: Ousman, Yesuf

description: The study was aimed at assessing the implementation of Ethiopian pastoral development policies and their impacts on the livelihood of pastoralist in Ewa district, Afar region. The study assessed the livelihood assets possession of pastoralist in Ewa and government efforts to improve pastoral livelihood. Qualitative and quantitative data collection techniques were employed to collect data from various sources. A sample of 142 households and six key informants were selected and data was collected using household survey, focus group discussion and key informant interviews. The findings of the study indicated that possession of important livelihood assets such as livestock, land and water, access to health and education, finance and market etc., are either deteriorated or remained poor. It was found that 97.2% of the families experienced reduced livestock holding, only 38% of households claimed to own land and 14.8%, meanwhile, have lost their land. The vulnerability condition instead is steadily growing. Partly inappropriateness and partly poor implementation of state policies such as settlement and unconsented projects coupled other factors contributed for the decline of livelihood condition. Generally, pastoralists in Ewa district today are at the crossroads and need decisive actions with far-reaching significances. Collective and private land rights have to be granted, access to market, income generating activities, increasing livestock productivity through improved technologies and supplementing with crop cultivations need to be introduced. As many pastoralists see themselves to be an agro pastoralist for the future, properly planned voluntary settlement of pastoralists along the resourceful riverbanks is also commendable if the livelihoods of pastoralists in Ewa has to improve.

description: We study a continous-time quantum walk on a path graph. In this paper, we show that, for any odd prime $p$ and positive integer $t$, the path on $2^t p - 1$ vertices admits pretty good state transfer between vertices $a$ and $n+1-a$ for each $a$ that is a multiple of $2^{t-1}$ with respect to the quantum walk model determined by the XY-Hamiltonian. This gives the first examples of pretty good state transfer occurring between internal vertices on a path, when it does not occur between the extremal vertices.

Non-minimally coupled dark fluid in Schwarzschild spacetime

description: If one assumes a particular form of non-minimal coupling, called the conformal coupling, of a perfect fluid with gravity in the fluid-gravity Lagrangian then one gets modified Einstein field equation. In the modified Einstein equation, the effect of the non-minimal coupling does not vanish if one works with spacetimes for which the Ricci scalar vanishes. In the present work we use the Schwarzschild metric in the modified Einstein equation, in presence of non-minimal coupling with a fluid, and find out the energy-density and pressure of the fluid. In the present case the perfect fluid is part of the solution of the modified Einstein equation. We also solve the modified Einstein equation, using the flat spacetime metric and show that in presence of non-minimal coupling one can accommodate a perfect fluid of uniform energy-density and pressure in the flat spacetime. In both the cases the fluid pressure turns out to be negative. Except these non-trivial solutions it must be noted that the vacuum solutions also remain as trivial valid solutions of the modified Einstein equation in presence of non-minimal coupling.
