description: We investigated the effect of uniaxial pressure (0-1000 bars) applied parallely to the ac electric field on dielectric properties of PLZT-x/65/35 (2 \leqslant x \leqslant 13) ceramics. There was revealed a significant effect of the external stress on these properties. The application of uniaxial pressure leads to the change of the peak intensity of the electric permittivity (\varepsilon), of the frequency dispersion as well as of the dielectric hysteresis. The peak intensity $\varepsilon$ becomes diffused/sharpened and shifts to a higher/lower temperatures with increasing the pressure. It was concluded that the application of uniaxial pressure induces similar effects as increasing the Ti ion concentration in PZT system. We interpreted our results based on the domain switching processes under the action of combined electromechanical loading.

description: We report on a detailed simulation study of the hadron energy resolution as a function of the thickness of the absorber plates for the proposed Iron Calorimeter (ICAL) detector at the India-based Neutrino Observatory (INO). We compare the hadron resolutions obtained with absorber thicknesses in the range 1.5--8 cm for neutrino interactions in the energy range 2--15 GeV, which is relevant to hadron production in atmospheric neutrino interactions. We find that at lower energies, the thickness dependence of energy resolution is steeper than at higher energies, however there is a thickness-independent contribution that dominates at the lower thicknesses discussed in this work. As a result, the gain in hadron energy resolution with decreasing plate thickness is marginal. We present the results in the form of fits to a function with energy-dependent exponent.

description: A calculation of the pion-production operator up to next-to-next-to-leading order for s-wave pions is performed within chiral effective field theory. In the previous study [Phys. Rev. C 85, 054001 (2012)] we discussed the contribution of the pion-nucleon loops at the same order. Here we extend that study to include explicit Delta degrees of freedom and the 1/m_N^2 corrections to the pion-production amplitude. Using the power counting scheme where the Delta-nucleon mass difference is of the order of the characteristic momentum scale in the production process, we calculate all tree-level and loop diagrams involving Delta up to next-to-next-to-leading order. The long-range part of the Delta loop contributions is found to be of similar size to that from the pion-nucleon loops which supports the counting scheme. The net effect of pion-nucleon and Delta loops is expected to play a crucial role in understanding of the neutral pion production data.

description: High-fidelity and robust quantum gates are essential for quantum information processing, where neutral Rydberg atoms trapped in optical tweezer arrays serving as a versatile platform for the implementation. We propose a rapid adiabatic passage (RAP) scheme for achieving a high-fidelity controlled-Z (CZ) gate on a neutral atom Rydberg platform. Utilizing only global laser dressing, our scheme involves echoing two identical RAP pulses within the Rydberg blockade regime to realize a CZ gate and can be readily extended to a C$^k$Z gate with additional qubits. We predict a CZ gate with fidelity over 0.9995 using akali-atom parameters, and a CCZ gate with fidelity exceeding 0.999. Moreover, the direct utilization of echoing RAP pulses enables the implementation of a four-bit CCCZ gate at fidelity over 0.996 without further optimization. The proposed scheme, remarkably robust to variations in driving fields and realistic decoherence effects, holds promise for future quantum information processing applications.

description: The search for the origin of charged cosmic rays remains one of the greatest challenges in astrophysics. Extremely accelerated particles propagate through the universe carrying the secrets of the most energetic cosmic phenomena. While neutral particles are not deflected by magnetic fields and point back to their sources, charged cosmic rays arrive on Earth as a diffuse flux, making it nearly impossible to identify their origin. The MAGIC telescopes, primarily designed to detect high-energetic gamma rays, also have the potential to study charged cosmic rays. This work presents the analysis chain to produce a proton spectrum from data measured with the MAGIC telescopes. The analysis chain includes data preparation, machine learning algorithms for particle reconstruction, and unfolding techniques which consider remaining background contributions. New simulations of air showers induced by charged cosmic rays are used in this analysis and tested accordingly. This work illustrates the potential of IACTs for the research of charged cosmic rays and provides the first proton spectrum of MAGIC, which constitutes a valuable addition to previous measurements by other cosmic-ray experiments.
description: Die Suche nach dem Ursprung der geladenen kosmischen Strahlung ist nach wie vor eine der größten Herausforderungen der Astrophysik. Extrem beschleunigte Teilchen propagieren durch das Universum und tragen die Geheimnisse der höchstenergetischen kosmischen Phänomene in sich. Während neutrale Teilchen nicht von Magnetfeldern abgelenkt werden und zu ihren Quellen zurückweisen, erreicht geladene kosmische Strahlung die Erde als diffuser Teilchenstrom, was es nahezu unmöglich macht, ihren Ursprung zu bestimmen. Die MAGIC-Teleskope, die in erster Linie für die Untersuchung von hochenergetischer Gammastrahlung konzipiert sind, haben auch das Potenzial, geladene kosmische Strahlung zu untersuchen. In dieser Arbeit wird die Analysekette zur Erstellung eines Protonenspektrums aus den mit den MAGIC-Teleskopen gemessenen Daten entwickelt. Die Analysekette umfasst die Datenaufbereitung, Algorithmen für maschinelles Lernen zur Teilchenrekonstruk- tion, und Entfaltungstechniken unter Berücksichtigung von verbliebenen Untergrund- beiträgen. Neue Simulationen der durch geladene kosmische Strahlung induzierten Luftschauer werden in dieser Analyse verwendet und entsprechend getestet. Diese Arbeit veranschaulicht das Potenzial von IACTs für die Forschung im Bereich der geladenen kosmischen Strahlung und liefert das erste Protonenspektrum von MAGIC, welches eine wertvolle Ergänzung zu den bisherigen Messungen anderer Experimente für kosmische Strahlung bildet.

description: Simulated annealing (SA) was inspired from annealing in metallurgy, a technique involving heating and controlled cooling of a material to increase the size of its crystals and reduce their defects, both are attributes of the material that depend on its thermodynamic free energy. In this Paper, firstly we will study SA in details on its practical implementation. Then, hybrid pure SA with local (or global) search optimization methods allows us to be able to design several effective and efficient global search optimization methods. In order to keep the original sense of SA, we clarify our understandings of SA in crystallography and molecular modeling field through the studies of prion amyloid fibrils.

description: New holographic prescription for the model of 3d higher-spin gravity coupled to real matter fields $B_{μν}$ and $C$, which was introduced in ArXiv:1304.7941[hep-th], is formulated. By using a local symmetry, two of the components of $B_{μν}$ are eliminated, and gauge-fixing conditions are imposed such that the non-vanishing component, $B_{ϕρ}$, satisfies a covariantly-constancy condition in the background of Chern-Simons gauge fields $A_μ$, $\bar{A}_μ$. In this model, solutions to the classical equations of motion for $A_μ$ and $\bar{A}_μ$ are non-flat due to the interactions with matter fields. The solutions for the gauge fields can, however, be split into two parts, flat gauge fields ${\cal A}_μ$, $\bar{\cal A}_μ$, and those terms that depend on the matter fields. The equations for the matter fields then coincide with covariantly-constancy equations in the flat backgrounds ${\cal A}_μ$ and $\bar{\cal A}_μ$, which are exactly the same as those in linearized 3d Vasiliev gravity. The two- and three-point correlation functions of operators in the boundary CFT are computed by using an on-shell action, $ \text{tr}\, (B_{ϕρ} \, C)$. This term does not depend on coordinates due to the matter equations of motion, and it is not necessary to take the near-boundary limit $ρ\rightarrow \infty$. Analysis is presented for SL(3,R) $\times$ SL(3,R) as well as $HS[\frac{1}{2}] \times HS[\frac{1}{2}]$ higher-spin gravity. In the latter model, scalar operators with scaling dimensions $Δ_+=\frac{3}{2}$ and $Δ_-=\frac{1}{2}$ appear in a single quantization.

Influence of the tectosphere upon plate motion

description: This paper tests two hypotheses for the influence of thick lithosphere (the tectosphere) upon plate motion. The first is that the tectosphere reaches down into high-viscosity regions of the asthenosphere, effectively slowing the motion of continental plates. The second is that the tectosphere reaches down below the slow-moving convective boundary layer into regions of rapid mantle convection and effectively speeds (or slows) the motion of continental plates. Our data imply that the tectosphere speeds plate motion rather than impedes plate motion and are thus most consistent with the second hypothesis.

description: The Point Defect Model (PDM) describes the corrosion resistance properties of oxide films based on interfacial reactions and defect transport, which are affected by the electric field inside the oxide film. The PDM assumes a constant electric field strength due to band-to-band tunneling (BTBT) of electrons and the separation of electrons and holes by high electric fields. In this manuscript we present a more complex expansion of the common models to simulate steady state oxide films to test this assumption. The R-PDM was extended by including the transport of electrons and holes and BTBT. It could be shown that BTBT only occurs in very rare cases of narrow band gaps and high electric fields and the impact of electrons and holes does indeed lead to a buffering effect on the electric field, but does not lead to a constant electric field strength. Modeling the transport of electrons and holes on the oxide film allows to specifically estimate their potential impact on the film growth. Especially during modeling of oxide films with narrow band gap and/or electrochemical reactions at the film/solution interface the electrons and holes needs to be included to the model.

This scattering process in the superradiant regime w>1 and for mirror radii r_m in the near-horizon region x_m=(r_m-r_+)/r_+<>(tau/x_m)^2>>1 regime, which implies that the instability timescale 1/w_I of the system can be made arbitrarily short in the qQ-->infinity limit. The short instability timescale found in the linear regime along with the spherical symmetry of the system, make the charged bomb a convenient toy model for future numerical studies aimed to investigate the non-linear end-state of superradiant instabilities.

description: The search of new topological insulators that demonstrate the quantum anomalous Hall effect (QAHE) is a cutting-edge research topic in condensed matter physics and materials science. So far, the QAHE has been observed only in Cr-doped (Bi,Sb)2Te3 at extremely low temperature. Therefore, it is important to find new materials with large topological band gap and high thermal stability for the realization of the QAHE. Based on first-principles and tight-binding model calculations, we discovered a new class of topological phase$-$Chern half metal which manifests the QAHE in one spin channel while is metallic in the other spin channel$-$in Co or Rh deposited graphene. Meanwhile, these systems have large perpendicular magnetic anisotropy energies of 5.3 and 11.5 meV, necessary for the observation of the QAHE at reasonably high temperature.

description: Thermal gradient measurements, consolidation tests, and pore water compositions from the Mariana Trough imply that water is moving through the sediments in areas with less than about 100 m of sediment cover. The maximum advection rates implied by the thermal measurements and consolidation tests may be as high as 10−5 cm s−1 but are most commonly in the range of 1 to 5×10−6 cm s−1. Theoretical calculations of the effect of the highest advection rates upon carbonate dissolution indicate that dissolution may be impeded or enhanced (depending upon the direction of flow) by a factor of 2 to 5 times the rate for diffusion alone. The average percentage of carbonate is consistently higher in two cores from the area with no advection or upward advection than the average percentage of carbonate in three cores from the area with downward advection. This increase in average amount of carbonate in cores with upward moving water or no movement cannot be attributed solely to differences in water depth or in amount of terrigenous dilution. If the sediment column acts as a passive boundary layer, then the water velocities necessary to affect chemical gradients of silica are in the range 10−9 to 10−10 cm s−l. However, if dissolution of silica occurs within the sediment column, then the advection velocities needed to affect chemical gradients are at least 3×10−8 cm s−l and may be as high as 3×10−6 cm s−l. This order of magnitude increase in advection velocities when chemical reactions occur within the sediments is probably applicable to other cations in addition to silica. If so, then the advection velocities needed to affect heat flow ( >10−8 cm s−1) and pore water chemical gradients are much nearer in magnitude than previously assumed.

description: We discuss measurability of phi, omega and rho mesons via di-electron decays in high-temperature states produced in heavy-ion collisions, equivalently at different pion multiplicities per heavy-ion collision dN_{pi^{0} + pi^{+-}}/dy = 1000 and 2700 intended for the most central Au+Au collisions at sqrt(s_{NN}) = 200 GeV (RHIC) and the most central Pb+Pb collisions at sqrt(s_{NN}) = 5.5 TeV (LHC), by evaluating the signal-to-background ratios and the statistical significance for the idealized detection system in the numerical simulation. The simulation study provides a guideline to be applicable to a concrete detector design by focusing on only the key experimental issues relevant to the measurement of di-electrons. The results suggest that there are realizable parameter ranges to measure light vector mesons via di-electrons with the reasonable significance level, even in the highest multiplicity case.

description: While accurate simulations of dense gas flows far from the equilibrium can be achieved by Direct Simulation adapted to the Enskog equation, the significant computational demand required for collisions appears as a major constraint. In order to cope with that, an efficient yet accurate solution algorithm based on the Fokker-Planck approximation of the Enskog equation is devised in this paper; the approximation is very much associated with the Fokker-Planck model derived from the Boltzmann equation [J. Comput. Phys., 229, 1077 (2010)]-[J. Fluid Mech., 680, 574 (2011)]. The idea behind these Fokker-Planck descriptions is to project the dynamics of discrete collisions implied by the molecular encounters into a set of continuous Markovian processes subject to the drift and diffusion. Thereby, the evolution of particles representing the governing stochastic process becomes independent from each-other and thus very efficient numerical schemes can be constructed. By close inspection of the Enskog operator, it is observed that the dense gas effects contribute further to the advection of molecular quantities. That motivates a modelling approach where the dense gas corrections can be cast in the extra advection of particles. Therefore, the corresponding Fokker-Planck approximation is derived such that the evolution in the physical space accounts for the dense effects present in the pressure, stress tensor and heat fluxes. Hence the consistency between the devised Fokker-Planck approximation and the Enskog operator is shown for the velocity moments up to the heat fluxes. For validation studies, a homogeneous gas inside a box besides Fourier, Couette and lid-driven cavity flow setups are considered. The results based on the Fokker-Planck model are compared with respect to benchmark simulations, where good agreements are found for the flow field along with the transport properties.

description: We present results from SEPPCoN, an on-going Survey of the Ensemble Physical Properties of Cometary Nuclei. In this report we discuss mid-infrared measurements of the thermal emission from 89 nuclei of Jupiter-family comets (JFCs). All data were obtained in 2006 and 2007 with the Spitzer Space Telescope. For all 89 comets, we present new effective radii, and for 57 comets we present beaming parameters. Thus our survey provides the largest compilation of radiometrically-derived physical properties of nuclei to date. We conclude the following. (a) The average beaming parameter of the JFC population is 1.03+/-0.11, consistent with unity, and indicating low thermal inertia. (b) The known JFC population is not complete even at 3 km radius, and even for comets with perihelia near ~2 AU. (c) We find that the JFC nuclear cumulative size distribution (CSD) has a power-law slope of around -1.9. (d) This power-law is close to that derived from visible-wavelength observations, suggesting that there is no strong dependence of geometric albedo with radius. (e) The observed CSD shows a hint of structure with an excess of comets with radii 3 to 6 km. (f) Our CSD is consistent with an intrinsic distribution that lacks many sub-kilometer objects.

description: With close pairs of quasars at different redshifts, a background quasar sightline can be used to study a foreground quasar's environment in absorption. We use a sample of 650 projected quasar pairs to study the HI Lya absorption transverse to luminous, z~2 quasars at proper separations of 30kpc < R < 1Mpc. In contrast to measurements along the line-of-sight, regions transverse to quasars exhibit enhanced HI Lya absorption and a larger variance than the ambient intergalactic medium, with increasing absorption and variance toward smaller scales. Analysis of composite spectra reveals excess absorption characterized by a Lya equivalent width profile W = 2.3A (R/100kpc)^-0.46. We also observe a high (~60%) covering factor of strong, optically thick HI absorbers (HI column log NHI > 17.3) at separations R<200kpc, which decreases to ~20% at R~1Mpc, but still represents a significant excess over the cosmic average. This excess of optically thick absorption can be described by a quasar-absorber cross-correlation function xi_QA(r) = (r/r_0)^gamma with a large correlation length r_0 = 12.5+2.7-1.4 Mpc/h (comoving) and gamma = 1.68+0.14-0.30. The HI absorption measured around quasars exceeds that of any previously studied population, consistent with quasars being hosted by massive dark matter halos Mhalo~10^12.5 Msun at z~2.5. The environments of these massive halos are highly biased towards producing optically thick gas, and may even dominate the cosmic abundance of Lyman limit systems and hence the intergalactic opacity to ionizing photons at z~2.5. The anisotropic absorption around quasars implies the transverse direction is much less likely to be illuminated by ionizing radiation than the line-of-sight, which we interpret in terms of the same obscuration effects frequently invoked in unified models of active galactic nuclei.

Κατέχοντας την απαιτούμενη τεχνογνωσία οι Αναπτυξιακές Τράπεζες, έχουν τη δυνατότητα να συνάπτουν συνεργασίες με ιδιωτικά χρηματοπιστωτικά ιδρύματα και διεθνείς χρηματοδοτικούς θεσμούς με σκοπό την παροχή χρηματοδοτικών εργαλείων για τη βελτίωση των όρων χρηματοδότησης των επιχειρήσεων. Σε επίπεδο κρατών-μελών της ΕΕ-27, οι Αναπτυξιακές Τράπεζες μπορούν να διαχειρίζονται μεταξύ άλλων και συγχρηματοδοτούμενους πόρους των Ευρωπαϊκών Διαρθρωτικών και Επενδυτικών Ταμείων για την επίτευξη των στόχων της κοινής περιφερειακής πολιτικής. Στο πλαίσιο της εταιρικής σχέσης μεταξύ της Ελλάδας και της ΕΕ-27, τα χρηματοδοτικά εργαλεία εντάχθηκαν στο ΕΣΠΑ 2014-2020 για την επίτευξη του θεματικού στόχου για την ενίσχυση της επιχειρηματικότητας και τη βελτίωση της ανταγωνιστικότητας των ΜμΕ. Εξετάζοντας ως μελέτη περίπτωσης τα χρηματοδοτικά εργαλεία δανειακού τύπου του Ταμείου Επιχειρηματικότητας ΙΙ (ΤΕΠΙΧ ΙΙ) της Ελληνικής Αναπτυξιακής Τράπεζας τα οποία συγχρηματοδοτήθηκαν από το ΕΣΠΑ 2014-2020, η παρούσα εργασία καταλήγει στα ακόλουθα συμπεράσματα: (α) Οι ποσοτικοί στόχοι του ΤΕΠΙΧ ΙΙ, δηλαδή το συνολικά διαθέσιμο ποσό των συγχρηματοδοτούμενων πόρων για χρηματοδοτικά εργαλεία καθώς κι ένα σημαντικό μέρος του χρηματοδοτικού κενού καλύφθηκαν σε ικανοποιητικό βαθμό. Κάτι που οφείλεται κατά κύριο λόγο στην έκτακτη ρευστότητα που πρόσφερε το ΤΕΠΙΧ ΙΙ για την αντιμετώπιση των αρνητικών οικονομικών συνεπειών των μέτρων έναντι της πανδημίας Covid-19. (β) Ωστόσο, τα χρηματοδοτικά εργαλεία του ΤΕΠΙΧ ΙΙ δεν άφησαν ιδιαίτερα αναπτυξιακά αποτελέσματα στην ελληνική οικονομία, κάτι που αποτέλεσε στόχο της περιφερειακής πολιτικής στο πλαίσιο του ΕΣΠΑ 2014-2020. Επιπρόσθετα, το κυριότερο πρόβλημα των ελληνικών ΜμΕ που είναι η πρόσβαση σε χρηματοδότηση, δεν αντιμετωπίσθηκε επιτυχώς, καθώς μόλις τρεις στις εκατό ΜμΕ είχαν πρόσβαση σε τραπεζικό δανεισμό μέσω του ΤΕΠΙΧ ΙΙ, γεγονός το οποίο έχει αρνητικές επιπτώσεις στην ανάπτυξη της ελληνικής οικονομίας.

description: We have found an impact crater that is likely < 6000 years old. Burckle crater is in the central Indian Ocean on the edge of a fracture zone at 30.87° S 61.36°E. The crater is 29±1 km wide and is the inferred source of layers with high magnetic susceptibility in 3 deep sea cores. Each layer goes to the top of the core. Two out of 3 of the cores have basal Pleistocene ages and the basal age of the third is unknown. The high susceptibility layers contain broken plagioclase, spinel periodotite, and chrysotile asbestos. One sample contains pure Ni with drops of oxidized Ni. Because pure Ni melts at 1453°C, it is very likely that the drops formed during an impact. The high susceptibility layers from 2 cores are over 5 times thicker than they should be for a 29 km wide source crater. We also find that a 29 km wide source crater cannot vaporize enough seawater to produce meters of rain, even in a restricted region between 4750 and 7250 km from the crater. Thus, we infer that Burckle crater was produced as part of a Shoemaker-Levy type impact of a comet. The fragmented comet also produced two other large impact centers, one in the northwest Pacific and another in the central eastern Pacific. Where the rainout from these impact centers overlaps, we see deluge events that are over a week long. The impact event also produced devastating tsunamis, winds, and associated social upheaval. We date the event to around 2807 B.C.

description: We have found seven discrete layers in a bog core from Cornwall, NY about 80 km away from the Atlantic Ocean. All but two layers contain material that is unlikely to be locally derived. In most cases, the material in the layers has been transported thousands of kilometers from its source area. Six out of the seven layers are difficult to explain except through impact processes. If all of these layers are derived from impacts that produced craters, the data imply a very high impact rate during late Holocene time. In addition, we have been able to associate two of the impact ejecta layers with dated tsunami events that span the Atlantic Ocean. If this discovery is validated by further research, it implies a much larger tsunami hazard in the Atlantic Ocean than previously reported.
