description: We introduce an experimental procedure for the detection of quantum entanglement of an unknown quantum state with as few measurements as possible. The method requires neither a priori knowledge of the state nor a shared reference frame between the observers. The scheme starts with local measurements, possibly supplemented with suitable filtering, that can be regarded as calibration. Consecutive correlation measurements enable detection of the entanglement of the state. We utilize the fact that the calibration stage essentially establishes the Schmidt decomposition for pure states. Alternatively we develop a decision tree which reveals entanglement within few steps. These methods are illustrated and verified experimentally for various two-qubit entangled states.

description: Wave propagation in ray-chaotic scenarios, characterized by exponential sensitivity to ray-launching conditions, is a topic of significant interest, with deep phenomenological implications and important applications, ranging from optical components and devices to time-reversal focusing/sensing schemes. Against a background of available results that are largely focused on the time-harmonic regime, we deal here with short-pulsed wavepacket propagation in a ray-chaotic enclosure. For this regime, we propose a rigorous analytical framework based on a short-pulsed random-plane-wave statistical representation, and check its predictions against the results from finite-difference-time-domain numerical simulations.

description: The behaviour of matter near zero temperature continuous phase transitions, or 'quantum critical points' (QCPs) is a central topic of study in condensed matter physics. In fermionic systems, fundamental questions remain unanswered: the nature of the quantum critical regime is unclear because of the apparent breakdown of the concept of the quasiparticle, a cornerstone of existing theories of strongly interacting metals. Even less is known experimentally about the formation of ordered phases from such a quantum critical 'soup'. Here, we report a study of the specific heat across the phase diagram of the model system Sr3Ru2O7, which features an anomalous phase whose transport properties are consistent with those of an electronic nematic. We show that this phase, which exists at low temperatures in a narrow range of magnetic fields, forms directly from a quantum critical state, and contains more entropy than mean-field calculations predict. Our results suggest that this extra entropy is due to remnant degrees of freedom from the highly entropic state above T_c. The associated quantum critical point, which is 'concealed' by the nematic phase, separates two Fermi liquids, neither of which has an identifiable spontaneously broken symmetry, but which likely differ in the topology of their Fermi surfaces.

description: We address the in-plane pressure-dependent electrodynamics of graphite through synchrotron based infrared spectroscopy and ab initio Density Functional Theory calculations. The Drude term remarkably increases upon pressure application, as a consequence of an enhancement of both electron and hole charge densities. This is due to the growth of the band dispersion along the k_z direction between the K and H points of the Brillouin zone. On the other hand, the mid-infrared optical conductivity between 800 and 5000 cm-1 is almost flat, and very weakly pressure dependent, at least up to 7 GPa. This demonstrates a surprising robustness of the graphene-like universal quantum conductance of graphite, even when the interlayer distance is significantly reduced.

description: In Deutschland gehen die letzten drei Kernkraftwerke Mitte April endgültig vom Netz. Die Energiekrise infolge des russischen Angriffskriegs in der Ukraine hat allerdings auch hierzulande Forderungen nach dem Bau neuer Kernreaktoren angeheizt. Eine ähnliche Debatte wird im Kontext der Klimakrise auch international geführt. Atomenergie war aber schon seit den 1950er Jahren eine der teuersten Energiequellen und ist dies bis heute. Zudem ist sie keine zeitnahe Lösung, da der Bau der Reaktoren Jahrzehnte dauert. Auch technisch ist kein signifikanter Durchbruch zu wettbewerblichen Reaktoren absehbar. Dies gilt sowohl für SMR (Small Modular Reactor)-Konzepte mit geringer Leistung als auch für andere, wie zum Beispiel schnelle Brutreaktoren. Diese Erkenntnis setzt sich inzwischen auch in Fachkreisen der Energiesystemmodellierung durch, in denen bisher aufgrund überoptimistischer Annahmen stets ein wesentlicher Anteil an Atomenergie vorhergesagt und erneuerbare Energien vernachlässigt wurden.

This shows that in fact the whole neutrino-mass extended standard model on noncommutative spacetime can the formulated in the new nonperturbative (in theta) approach which eliminates the previous restriction of Seiberg-Witten map based theories to low-energy phenomena. Spacetime noncommutativity induced couplings between neutrinos and photons as well as Z-bosons appear quite naturally in the model. We derive relevant Feynman rules for the type I seesaw mechanism.

description: Abstract
The current study demonstrates a novel feeding trial employing O. mossambicus as a model organism by bio-encapsulating C. transvaalensis with K. alvarezii to enhance health status and growth, to prevent and manage the negative effects of A. hydrophila infection. A total of 150 Oreochromis mossambicus were taken randomly and divided into five experimental units (10 fishes per unit) with triplicates.Fish fed with C. transvaalensis which were bio-encapsulated with K.alvarezii was designated as (CTKA) individually. The Experimental Units were T0-(1gm of CT), T1-(1gm of CTKA for 24hr), T2-(1gm of CTKA for 48hr) and T3-(1gm of CTKA for 72hr) per 1 liter of water individually. After bio-encapsulation the live larvae were freeze dried for the purpose of removing moisture content and for long time storage. Results was a consistent improvement in the total WBC and RBC count, total serum protein, and phagocytic activity during the course of the 75th day of the investigation.The growth parameters were measured on day 30 and day 60.Digestive enzymes activity,liver specific enzymes activity,liver antioxidant activity were investigated after 60 days feeding trial. All these enzymes were positively performed in all experimental diet, while T3 experimental diet significantly enhanced all enzymes activities.As part of the post-challenge investigation (disease resistance test), the rate of survival and percentage of mortality of the fish were tracked and recorded after being exposed to A. hydrophila for 15 days. Therefore, fish farmers may be encouraged to do this to enhance the health status, boostup growth, and prevent microbial infections in the freshwater fish O. mossambicus by feeding (CTKA) for 72hrs.

description: We present the first dynamical mass estimates and scaling relations for a sample of Sunyaev-Zel'dovich effect (SZE) selected galaxy clusters. The sample consists of 16 massive clusters detected with the Atacama Cosmology Telescope (ACT) over a 455 sq. deg. area of the southern sky. Deep multi-object spectroscopic observations were taken to secure intermediate-resolution (R~700-800) spectra and redshifts for ~60 member galaxies on average per cluster. The dynamical masses M_200c of the clusters have been calculated using simulation-based scaling relations between velocity dispersion and mass. The sample has a median redshift z=0.50 and a median mass M_200c~12e14 Msun/h70 with a lower limit M_200c~6e14 Msun/h70, consistent with the expectations for the ACT southern sky survey. These masses are compared to the ACT SZE properties of the sample, specifically, the match-filtered central SZE amplitude y, the central Compton parameter y0, and the integrated Compton signal Y_200c, which we use to derive SZE-Mass scaling relations. All SZE estimators correlate with dynamical mass with low intrinsic scatter (

description: One of the many problems to which J.S. Dowker devoted his attention is the effect of a conical singularity in the base manifold on the behavior of the quantum fields. In particular, he studied the small-$t$ asymptotic expansion of the heat-kernel trace on a cone and its effects on physical quantities, as the Casimir energy. In this article we review some peculiar results found in the last decade, regarding the appearance of non-standard powers of $t$, and even negative integer powers of $\log{t}$, in this asymptotic expansion for the selfadjoint extensions of some symmetric operators with singular coefficients. Similarly, we show that the $ζ$-function associated to these selfadjoint extensions presents an unusual analytic structure.

Investigation of Notch and nitric oxide signaling in the cardiovascular system
Creators: name: Chang, Alex Chia Yu
Publisher: name: University of British Columbia
Year: 2012

description: Notch signaling is evolutionarily conserved and regulates various developmental and pathological processes. We are interested in the role of Notch signaling in cardiac valve formation and postnatal vascular remodeling. The heart is the first organ to form in a developing embryo and a common site of congenital defects. Valvuloseptal defects are the most common of the cardiac anomalies seen in the newborn with a prevalence of 1-2% and are often a result of deregulated atrioventricular canal (AVC) formation. The process of endothelial-to-mesenchymal-transition (EndMT) is required for the growth and maturation of the AVC and Notch signaling has been shown to induce this process. In chapter 3, we identify a novel link between Notch and Nitric Oxide (NO) signaling during EndMT. We show that Notch-activation directly induces GUCY1A3 and GUCY1B3, the soluble guanylyl cyclase that forms the heterodimeric NO receptor, during EndMT. We also show that Notch-induced expression and secretion of the TGFβ family member, Activin A, results in increased NO production via a PI3-kinase/Akt signaling mechanism. Paracrine activation of NO signaling by Activin A contributes to early onset of EndMT in the developing AVC. Functional arteries are essential for restoring blood flow and tissue regeneration in response to hypoxia, ischemia, or wound healing. Arterial obstruction can cause distal tissue ischemia and requires rapid reperfusion to limit tissue necrosis. Ischemia recovery requires two processes: angiogenesis (capillary sprouting) and arteriogenesis (expansion of existing vessels secondary to mechanical stress or chemical stimuli). Arteriogenesis involves two phases: a rapid vasodilatory phase followed by vascular expansion and remodeling. In chapter 4, we examine the relationship of endothelial Notch signaling and arteriogenesis using a hindlimb ischemia model. As the link between Notch and NO signaling unfolded in the heart study, we turned our attention to the NO pathway in the initial phase of arteriogenesis – vasodilation. The data presented in this dissertation defines a novel link between Notch signaling and NO signaling in the cardiovascular system and may help to explain Notch-induced EndMT in other pathologies.

description: In this paper, we consider the Universe deep inside of the cell of uniformity. At these scales, the Universe is filled with inhomogeneously distributed discrete structures (galaxies, groups and clusters of galaxies), which disturb the background Friedmann model. We propose mathematical models with conformally flat, hyperbolic and spherical spaces. For these models, we obtain the gravitational potential for an arbitrary number of randomly distributed inhomogeneities. In the cases of flat and hyperbolic spaces, the potential is finite at any point, including spatial infinity, and valid for an arbitrary number of gravitating sources. For both of these models, we investigate the motion of test masses (e.g., dwarf galaxies) in the vicinity of one of the inhomogeneities. We show that there is a distance from the inhomogeneity, at which the cosmological expansion prevails over the gravitational attraction and where test masses form the Hubble flow. For our group of galaxies, it happens at a few Mpc and the radius of the zero-acceleration sphere is of the order of 1 Mpc, which is very close to observations. Outside of this sphere, the dragging effect of the gravitational attraction goes very fast to zero.

description: We integrate numerically the nonlinear equation of motion for a collapsing spherical wavepacket in the context of theories that are expected to display behavior characteristic of classicalization. The classicalization radius sets the scale for the onset of significant deformations of the collapsing configuration, which result in the formation of shock fronts. A characteristic observable feature of the classicalization process is the creation of an outgoing field configuration that extends far beyond the classicalization radius. This feature develops before the deformed wavepacket reaches distances of the order of the fundamental scale. We find that in some models the scattering problem may not have real solutions over the whole space at late times. We determine the origin of this behavior and discuss the consistency of the underlying models.

description: We develop a full microscopic replica field theory of the dynamical transition in glasses. By studying the soft modes that appear at the dynamical temperature we obtain an effective theory for the critical fluctuations. This analysis leads to several results: we give expressions for the mean field critical exponents, and we study analytically the critical behavior of a set of four-points correlation functions from which we can extract the dynamical correlation length. Finally, we can obtain a Ginzburg criterion that states the range of validity of our analysis. We compute all these quantities within the Hypernetted Chain Approximation (HNC) for the Gibbs free energy and we find results that are consistent with numerical simulations.

Every ergodic system with positive Kolmogorov--Sinai entropy is measure-theoretically$^+$ chaotic (even in a bit stronger uniform sense). We provide an example showing that the latter statement cannot be reversed, a system of entropy zero with uniform measure-theoretic$^+$ chaos. \bigskip \centerline{\bf Résumé} Nous introduisons de nouveaux invariants pour les systèmes dynamiques définis sur des espaces probabilisés standards, appelés respectivement {\rm chaos mesuré} et {\rm chaos$^+$ mesuré}.

description: We discuss cosmological hydrodynamic simulations of galaxy formation performed with the new moving-mesh code AREPO, which promises higher accuracy compared with the traditional SPH technique that has been widely employed for this problem. We use an identical set of physics in corresponding simulations carried out with the well-tested SPH code GADGET, adopting also the same high-resolution gravity solver. We are thus able to compare both simulation sets on an object-by-object basis, allowing us to cleanly isolate the impact of different hydrodynamical methods on galaxy and halo properties. In accompanying papers, we focus on an analysis of the global baryonic statistics predicted by the simulation codes, (Vogelsberger et al. 2011) and complementary idealized simulations that highlight the differences between the hydrodynamical schemes (Sijacki et al. 2011). Here we investigate their influence on the baryonic properties of simulated galaxies and their surrounding haloes. We find that AREPO leads to significantly higher star formation rates for galaxies in massive haloes and to more extended gaseous disks in galaxies, which also feature a thinner and smoother morphology than their GADGET counterparts. Consequently, galaxies formed in AREPO have larger sizes and higher specific angular momentum than their SPH correspondents. The more efficient cooling flows in AREPO yield higher densities and lower entropies in halo centers (and the opposite trend in halo outskirts) leading to higher star formation rates of massive galaxies. While both codes agree to acceptable accuracy on a number of baryonic properties of cosmic structures, our results clearly demonstrate that galaxy formation simulations greatly benefit from the use of more accurate hydrodynamical techniques such as AREPO.

description: Der Gender Pay Gap, also die Verdienstlücke zwischen Frauen und Männern, beträgt in Deutschland nach wie vor 18 Prozent. Dieser Durchschnittswert ist allerdings nicht für alle Beschäftigten gleich. Große Unterschiede finden sich insbesondere nach dem Alter: Ab einem Alter von 30 Jahren steigt der Gender Pay Gap stark an und bleibt bis zum Ende des Erwerbslebens mit über 20 Prozent konstant hoch. Damit in engem Zusammenhang steht der Gender Care Gap, also der Unterschied in der unbezahlten Sorgearbeit zwischen Frauen und Männern. Auf Basis von Daten des Sozio-oekonomischen Panels (SOEP) zeigt dieser Bericht, dass auch der Gender Care Gap im mittleren Alter zunimmt: Frauen zwischen 35 und 39 Jahren leisten mit rund neun Stunden pro Tag mehr als doppelt so viel Care-Arbeit wie gleichaltrige Männer. Die Phase der Familiengründung bleibt sowohl für die Zeitverwendung als auch für die Lohnentwicklung vieler Frauen somit einschneidend. Will die Politik hieran etwas ändern, muss sie Anreize für eine gleichmäßigere Aufteilung der Sorgearbeit zwischen Frauen und Männern schaffen. Ein Ansatzpunkt ist eine Ausweitung der Partnermonate beim Elterngeld. Überfällig ist zudem eine Reform des Ehegattensplittings und der Minijobs.

Hall sensor-based locking electric differential system for BLDC motor driven electric vehicle with independent wheel drives
Creators: name: Gougani, Milad
Publisher: name: University of British Columbia
Year: 2012

description: It is generally known that stability of vehicles under certain driving conditions may be improved by forcing the wheels to turn at the same speed and angle regardless of the available traction under individual wheels. For conventional all-terrain vehicles or sport-utility vehicles, this function can be achieved by locking the mechanical differential system. In this thesis, we propose an innovative approach for locking the electrical differential system (EDS) of electric vehicles (EV) with independent brushless DC (BLDC) machine-based wheel drives. The proposed method locks the active wheels of the vehicle as if they were operating on a common “virtual” shaft. The locking algorithm is implemented by processing the Hall sensor signals of the considered motors and driving them with a single set of “averaged” Hall signals, thereby operating the motors at the same speed and angle. A detailed switch-level model of EDS embedded with the proposed Sync-Lock Control (SLC) along with the BLDC propulsion motors has been developed and compared against measurements for the considered BLDC propulsion motors. The proposed technique is shown to achieve better results compared to a conventional speed control loop as the considered motors are locked directly through the corresponding magnetic fields. An efficient realization of the proposed controller is presented that makes it possible to be potentially programmed inside existing motor controllers or implemented in a stand-alone microcontroller which can be packaged into a dongle circuit. The proposed SLC is implemented digitally using a programmable integrated circuit microcontroller. First, the Hall signals undergo a layer of filtering to mitigate the errors that are common due to Hall sensor misalignment in low-cost BLDC motors. Then, the locking algorithm is implemented by averaging the filtered Hall sensor signals. The SLC prototype is implemented in form of a standalone dongle-circuit that can be easily placed between the original Hall-sensors and the BLDC motor driver. Operation of typical industrial BLDC motors with the proposed controller is shown to outperform conventional controllers and lock both speed and angle of the motors.

description: Quantum and classical pairwise correlations in two typical collective spin systems (i.e., the Dicke model and the Lipkin-Meshkov-Glick model) are discussed. These correlations in the thermodynamical limit are obtained analytically and in a finite-size system are calculated numerically. Large-size scaling behavior for the quantum discord itself is observed, which has never been reported in another critical system. A logarithmic diverging behavior for the first derivative of the quantum discord is also found in both models, which might be universal in the second-order quantum phase transition. It is suggested that the pronounced maximum or minimum of first derivative of quantum discord signifies the critical point. Comparisons between the quantum discord and the scaled concurrence are performed. It is shown that the quantum discord is very small in one phase and robust in the other phase, while the scaled concurrence shows maximum at the critical point and decays rapidly when away from the the critical point.

English class assignments, school newspaper articles, emails and reading journal responses tell the story of Arthur Bean, a grade seven kid desperate to win the city-wide short story contest. The problem is, he’s kind of out of ideas right now. In a moment of desperation, he steals the story of his secret love, his creative writing partner Kennedy Laurel. When both stories get chosen as final contest submissions, Arthur needs to find a new story. A solution comes from an unlikely ally, Arthur’s tutoring partner and bully Robbie Zack, but at a price.

description: When are athermal soft sphere packings jammed ? Any experimentally relevant definition must at the very least require a jammed packing to resist shear. We demonstrate that widely used (numerical) protocols in which particles are compressed together, can and do produce packings which are unstable to shear - and that the probability of generating such packings reaches one near jamming. We introduce a new protocol that, by allowing the system to explore different box shapes as it equilibrates, generates truly jammed packings with strictly positive shear moduli G. For these packings, the scaling of the average of G is consistent with earlier results, while the probability distribution P(G) exhibits novel and rich scaling

Los gestos representativos influencian el pensamiento y el discurso
Creators: name: Valderrama Cárdenas, Juan Carlos
Publisher: name: Zenodo
Year: 2022
Subjects: gesto, comunicación, pensamiento, discurso, educación, aprendizaje, cognición

description: El presente estudio se basa en los recursos comunicacionales en la relación profesor-estudiante, especialmente en la construcción del discurso hablado en la interacción, teniendo en cuenta prácticas que pueden favorecer la comprensión mutua; se partió de la idea que las manos reflejan el contenido del pensamiento. Se pretendió conocer las implicaciones de la “manipulación” de los gestos de las manos en el discurso de 20 estudiantes universitarios. A los participantes se les presento una escena de una caricatura y se les solicito re-contar la historia a otro participante que no conoce la escena, la situación cuenta con dos momentos: a) relato libre y b) relato con estimulación del uso de gestos. Todas las aplicaciones se realizaron con cámara frontal y los vídeos fueron codificados con ELAN; el criterio de marcación fue que el gesto fuera co-expresivo al habla y que la trayectoria fuera claramente definida. Se encontró que en la situación libre la narración es más corta y de menor complejidad; en la situación de favorecer los gestos se usan mayor número de frases gestuales y palabras. Como conclusión se argumenta que la comunicación en la educación se favorece si se usan recursos verbales y no-verbales, lo cual tiene implicaciones para el profesor y el estudiante en la ilustración-transmisión de ideas y conceptos.
A time dependent Markovian master equation for adiabatic systems and its application to the Cooper pair pumping

description: For adiabatically and periodically manipulated dissipative quantum systems we derive, using Floquet theory, a simple Markovian master equation. Contrary to some previous works we explicitly take into account the time dependence of the Hamiltonian and, therefore, obtain a master equation with a time-dependent dissipative part. We illustrate our theory with two examples and compare our results with the previously proposed master equations. In particular, we consider the problem of Cooper pair pumping and demonstrate the inadequacy of the secular (rotating wave) approximation when calculating the pumped charge. The secular approximation producing a master equation of the Lindblad type approximates well the quantum state (density matrix) of the system, while to determine the pumped charge a non-Lindblad master equation beyond the rotating wave approximation is necessary.

description: Vicious Brownian motion is a diffusion scaling limit of Fisher's vicious walk model, which is a system of Brownian particles in one dimension such that if two of them meet they kill each other. We consider the vicious Brownian motion conditioned never to collide with each other, and call it the noncolliding Brownian motion. This conditional diffusion process is equivalent to the eigenvalue process of a Hermitian-matrix-valued Brownian motion studied by Dyson. Recently O'Connell introduced a generalization of the noncolliding Brownian motion by using the eigenfunctions (the Whittaker functions) of the quantum Toda lattice in order to analyze a directed polymer model in 1+1 dimensions. We consider a system of one-dimensional Brownian motions with a long-ranged killing term as a generalization of the vicious Brownian motion and construct the O'Connell process as a conditional process of the killing Brownian motions to survive forever.

description: Durch die Corona-Pandemie und insbesondere den russischen Angriffskrieg in der Ukraine sind die Energiepreise stark gestiegen. Die damit einhergehende hohe Verbraucherpreisinflation zwingt die Europäische Zentralbank (EZB) ihrem Mandat entsprechend zum Handeln. Jedoch äußerte die EZB zunächst selbst Zweifel, etwas gegen die Energiepreissteigerungen ausrichten zu können. Wie dieser Wochenbericht auf Basis einer Analyse struktureller Zusammenhänge im Euroraum unterstreicht, ist die EZB mit Blick auf die Energiepreisentwicklung jedoch alles andere als machtlos: Nachdem bereits im vergangenen Jahr in einem Wochenbericht gezeigt wurde, dass Kraftstoff- und Heizkosten im Zuge einer Zinserhöhung grundsätzlich sinken, identifiziert der vorliegende Bericht drei geldpolitische Wirkungskanäle. Dabei kommt es zu teils gegenläufigen Effekten. Es zeigt sich aber, dass die EZB mit Leitzinserhöhungen die Energiepreise unter dem Strich tatsächlich dämpfen kann.

Approximate sampling formulae for general finite-alleles models of mutation

description: Many applications in genetic analyses utilize sampling distributions, which describe the probability of observing a sample of DNA sequences randomly drawn from a population. In the one-locus case with special models of mutation such as the infinite-alleles model or the finite-alleles parent-independent mutation model, closed-form sampling distributions under the coalescent have been known for many decades. However, no exact formula is currently known for more general models of mutation that are of biological interest. In this paper, models with finitely-many alleles are considered, and an urn construction related to the coalescent is used to derive approximate closed-form sampling formulas for an arbitrary irreducible recurrent mutation model or for a reversible recurrent mutation model, depending on whether the number of distinct observed allele types is at most three or four, respectively. It is demonstrated empirically that the formulas derived here are highly accurate when the per-base mutation rate is low, which holds for many biological organisms.

On Wormhole Throats in $f(R)$ Gravity Theory

description: We study the existence and properties of wormhole throats in modified $f(R)$ gravity theory. Specifically, we concentrate on the cases where the lapse is not necessarily constant, and hence are not limited to the zero tidal force scenarios. In the class of theories whose actions are generated by Lagrangians of the form $f(R)=\sum α_{n}\,R^{n}$ we find parameters which allow for the existence of energy condition respecting throats, which do not exist in Einstein gravity. We also consider the effect of the modified action on the anisotropy of the models, and find that modified gravity can minimize the amount of anisotropy required to support the existence of a throat. In both these respects, the sector containing theories with positive $n$ is more promising than the negative $n$ sector in comparison to Einstein gravity alone, with large $n$ being most favorable

description: We review the new theory of modified supergravity, dubbed F(\cal R) supergravity, and some of its recent applications to inflation and reheating in the early universe cosmology. The F(\cal R) supergravity is the N=1 locally supersymmetric extension of the f(R) gravity in four space-time dimensions. A manifestly supersymmetric formulation of the F(\cal R) supergravity exist in terms of N=1 superfields, by using the (old) minimal Poincar'e supergravity in curved superspace. We find the conditions for stability, the absence of ghosts and tachyons. Three models of the F(\cal R) supergravity are studied. The first example is devoted to a recovery of the standard (pure) N=1 supergravity with a negative cosmological constant from the F(\cal R) supergravity. As the second example, a generic {\cal R}^2-type supergravity is investigated, and the existence of the AdS bound on the scalar curvature is found. As the third (and most important) example, a simple viable realization of chaotic inflation in supergravity is found. Our approach is {\it minimalistic} since it does not introduce new exotic fields or new interactions, beyond those already present in (super)gravity. The universal reheating mechanism is automatic. We establish the consistency of our approach and also apply it to preheating and reheating after inflation. The Higgs inflation and its correspondence to the Starobinsky inflation is established in the context of supergravity. We briefly review other relevant issues such as non-Gaussianity, CP-violation, origin of baryonic asymmetry, lepto- and baryo-genesis. The F(\cal R) supergravity has promise for possible solutions to those outstanding problems too.

description: Level densities of 2⁺ states in ⁴⁰Ca have been extracted from the high energy-resolution (p,p′) experimental data by means of a fluctuation analysis. Two different methods of background determination have been considered, namely, Quasi-free calculations and Discrete Wavelet Transform (DWT) technique. The results are then compared to theoretical models based on phenomenological and microscopic approaches.
