description: We analyze the orbits of stars and dark matter particles in the halo of a disk galaxy formed in a cosmological hydrodynamical simulation. The halo is oblate within the inner ~20 kpc and triaxial beyond this radius. About 43% of orbits are short axis tubes - the rest belong to orbit families that characterize triaxial potentials (boxes, long-axis tubes and chaotic orbits), but their shapes are close to axisymmetric. We find no evidence that the self-consistent distribution function of the nearly oblate inner halo is comprised primarily of axisymmetric short-axis tube orbits. Orbits of all families, and both types of particles are highly eccentric with mean eccentricity >0.6. We find that randomly selected samples of halo stars show no substructure in "integrals of motion" space. However individual accretion events can be clearly identified in plots of metallicity versus formation time. Dynamically young tidal debris is found primarily on a single type of orbit. However, stars associated with older satellites become chaotically mixed during the formation process (possibly due to scattering by the central bulge and disk, and baryonic processes), and appear on all four types of orbits. We find that the tidal debris in cosmological hydrodynamical simulations experiences significantly more chaotic evolution than in collisionless simulations, making it much harder to identify individual progenitors using phase space coordinates alone. However by combining information on stellar ages and chemical abundances with the orbital properties of halo stars in the underlying self-consistent potential, the identification of progenitors is likely to be possible.

description: The weak field approximation in a model of de Sitter gravity is investigated in the static and spherically symmetric case, under the assumption that the vacuum spacetime without perturbations from matter fields is a torsion-free de Sitter spacetime. It is shown on one hand that any solution should be singular at the center of the matter field, if the exterior is described by a Schwarzschild-de Sitter spacetime and is smoothly connected to the interior. On the other, all the regular solutions are obtained, which might be used to explain the galactic rotation curves without involving dark matter.

CONSUMERS' VALUE PERCEPTIONS ON SPARKLING WINE AND PURCHASING INTENTION: THE IMPACT OF COUNTRY OF ORIGIN AND PURCHASING PURPOSES
Creators: name: Li, Xinyue
Publisher: name: Purdue University Graduate School
Year: 2022
Subjects: Consumer behaviour

description: The purpose of the present study was to investigate the influence of purchasing purposes and country of origin on consumer’s purchasing intentions for sparkling wine, considering the effect of consumer’s value perceptions on the product. Two study populations were investigated: general U.S. wine consumers and self-identified food and beverage practitioners. It was found that for the general U.S. wine consumers, buying wine for gift giving or self-gifting would result in different purchasing intention and perceived emotional-social value, but Country of Origin (e.g., French Champagne or U.S. Sparkling Wine) did not result in any differences in purchasing intentions or perceived values. The practitioner group did not note any significant differences between scenarios given the purchasing purposes and country of origin on their purchasing intentions and perceived values. Correlations of perceived emotional-social value, perceived price value and purchasing intention were found. Several practical and theoretical implications were presented.

Κύριος στόχος ήταν η εξάλειψη των δυσκολιών και των αυστηρών κριτηρίων που εμπεριέχονται στην κλασσική διαδικασία, που έχει θεσμοθετηθεί από τα χρηματοπιστωτικά ιδρύματα. Δημιουργήθηκε έτσι, μια νέα καινοτομία, το Peer-to-Peer Lending, ξεκινώντας από το Ηνωμένο Βασίλειο ως μια ηλεκτρονική πλατφόρμα κοινωνικής δικτύωσης και αργότερα και σε άλλες χώρες της Ευρώπης, της Ασίας και της Αμερικής. Η πλατφόρμα απευθύνεται σε κάθε άτομο ή ομάδα ατόμων που αναζητούν νέες πηγές χρηματοδότησης ή αντίστοιχα θέλουν να επενδύσουν με στόχο το χρηματικό κέρδος. Η αμφίδρομη αυτή διαδικασία, απλοποιεί αρκετά την κλασσική, αφού ταυτίζεται σε μεγάλο βαθμό με τον πλειστηριασμό του επιτοκίου του δανείου. Σε αυτή την περίπτωση όμως, εμπεριέχονται κίνδυνοι φερεγγυότητας από την πλευρά των δανειοληπτών ως προς την αποπληρωμή του δανείου. Αυτούς τους κινδύνους προσπάθησαν οι ερευνητές να προβλέψουν με ορισμένες μεταβλητές που εμπεριέχουν τα οικονομικά στοιχεία της κάθε πλευράς. Ταυτόχρονα όμως, επιτακτική είναι και η ανάγκη εύρεσης νέων και πιο εξελιγμένων τρόπων που θα είναι σε θέση να προβλέπουν με μεγαλύτερη ακρίβεια την αποπληρωμή ή όχι ενός δανείου.

description: Stroke rehabilitation consists of restorative and adaptive approaches. Multiple adaptive approaches exist. The objective of this study was to develop a framework for categorising adaptive stroke rehabilitation interventions, based on underlying theory. We searched multiple databases to April 2020 to identify studies of interventions designed to improve participation in valued activities. We extracted the name of the intervention, underlying explicit or implicit theory, intervention elements, and anticipated outcomes. Using this information, we proposed distinct groups of interventions based on theoretical drivers. Twenty-nine adaptive interventions were examined in at least one of 77 studies. Underlying theories included Cognitive Learning Theory, Self-determination Theory, Social Cognitive Theory, adult learning theories, and Psychological Stress and Coping Theory. Three overarching theoretical drivers were identified: learning, motivation, and coping. At least 29 adaptive approaches exist, but each appear to be based on one of three underlying theoretical drivers. Consideration of effectiveness of these approaches by theoretical driver could help indicate underlying mechanisms and essential elements of effective adaptive approaches. Our framework is an important advance in understanding and evaluating adaptive approaches to stroke rehabilitation.

description: We consider the spatially flat Friedmann-Lemaitre-Robertson-Walker space time in the teleparallel model of gravity and assume that the universe is filled nearly by cold dark matter and a nonminimally coupled scalar field with a power-law potential as dark energy. We investigate the possibility that the universe undergoes a transition from quintessence to phantom phase. An analytical solution for the scalar field is obtained and necessary conditions required for such a transition are discussed.

description: Wide binaries made up of two white dwarfs (WDs) receive far less attention than their tight counterparts. However, our tests using the binary population synthesis code {\tt StarTrack} indicate that, for any set of reasonable initial conditions, there exists a significant observable population of double white dwarfs (WDWDs) with orbital separations of 10$^2$ to 10$^5$ AU. We adapt the technique of Dhital et al.\ to search for candidate common proper motion WD companions separated by $<10\amin$ around the $>$12,000 spectroscopically confirmed hydrogen-atmosphere WDs recently identified in the Sloan Digital Sky Survey. Using two techniques to separate random alignments from high-confidence pairs, we find nine new high-probability wide WDWDs and confirm three previously identified candidate wide WDWDs. This brings the number of known wide WDWDs to 45; our new pairs are a significant addition to the sample, especially at small proper motions ($$10\asec). Spectroscopic follow-up and an extension of this method to a larger, photometrically selected set of SDSS WDs may eventually produce a large enough dataset for WDWDs to realize their full potential as testbeds for theories of stellar evolution.

description: We study aspects of quantum cosmology in the presence of a modified space-time geometry. In particular, within the context of Gravity's Rainbow modified geometry, motivated from quantum gravity corrections at the Planck energy scale, we show that the distortion of the metric leads to a Wheeler-De Witt equation whose solution admits outgoing plane waves. Hence, a period of cosmological inflation may arise without the need for introducing an inflaton field.

description: Many-body quantum systems in the ground states have zero-point energy due to the uncertainty relation. In many cases, the system in the ground state accompanies spatially-entangled energy density fluctuation via the noncommutativity of the energy density operators, though the total energy takes a fixed value, i.e. the lowest eigenvalue of the Hamiltonian. Quantum energy teleportation (QET) is protocols for extraction of the zero-point energy out of one subsystem using information of a remote measurement of another subsystem. From an operational viewpoint of protocol users, QET can be regarded as an effective rapid energy transportation without breaking all physical laws including causality and local energy conservation. In the protocols, the ground-state entanglement plays a crucial role. In this paper, we show analytically for a general class of spin-chain systems that the entanglement entropy is lower bounded by a positive quadratic function of the teleported energy between the regions of a QET protocol. This supports a general conjecture that ground-state entanglement is an evident physical resource for energy transportation in the context of QET. The result may also deepen our understanding of the energy density fluctuation in condensed matter systems from a new perspective of quantum information theory.

description: The use of traditional medicine is attributable not only to cultural and poverty reasons but also to the ineffectiveness of many existing medicines. The lack of effective pharmaceutical formulas and the resistance created by current antibiotic pathogens, as well as oxidative stress new therapeutic agents from plants. In fact, several studies have shown that medicinal plants possess antioxidant properties due largely to their phytochemical profile. In addition, they can prevent oxidative modification by neutralizing free radicals, oxygen scavenging, or decomposing peroxides through their antioxidant activities. Endemic plants can be a source of new bioactive compounds able to prevent several diseases such as cancer, diabetes, hypertension, and Alzheimer’s disease by combating oxidative stress and its associated pathologies. The purpose of this study was to evaluate the contents of total phenolics, flavonoids, and caffeine in six medicinal plants used traditionally in phytotherapy, usually consumed as tea or infusion namely: Camellia sinensis, Melissa officinalis, Lippia citriodora, Cymbopogon citratus, Matricaria chamomilla, and Tilia cordata. Significant variations in total phenolics and flavonoids content were found among analyzed plants and depending on the nature of the extract. The concentration of caffeine was also very dissimilar and followed the sequence M. officinalis < T. cordata < C. citratus < M. chamomilla < L. citriodora < C. sinensis. Also, the antioxidant activity of each plant was found to vary according to C. citratus (90.9%) > C. sinensis (87.8%) > M. officinalis (50.7%) > M. chamomilla (45.3%) > T. cordata (32.2%) > L. citriodora (28.0%).

description: An obfuscator is an algorithm that translates circuits into functionally-equivalent similarly-sized circuits that are hard to understand. Efficient obfuscators would have many applications in cryptography. Until recently, theoretical progress has mainly been limited to no-go results. Recent works have proposed the first efficient obfuscation algorithms for classical logic circuits, based on a notion of indistinguishability against polynomial-time adversaries. In this work, we propose a new notion of obfuscation, which we call partial-indistinguishability. This notion is based on computationally universal groups with efficiently computable normal forms, and appears to be incomparable with existing definitions. We describe universal gate sets for both classical and quantum computation, in which our definition of obfuscation can be met by polynomial-time algorithms. We also discuss some potential applications to testing quantum computers. We stress that the cryptographic security of these obfuscators, especially when composed with translation from other gate sets, remains an open question.

A fast procedure to estimate the prevailing rupture propagation direction and how it applies to the 2016-2017 Central Italy seismic sequence

Publisher: name: Zenodo

description: We present a new approach aimed to generalize the statistical procedure proposed by Calderoni et al., (2017) to estimate the prevailing direction of rupture propagation in a given region during a seismic sequence. We apply this procedure to the strongest earthquakes (Mw ≥ 4.4) of the 2016-2017 Central Italy seismic sequence and compare our results with other studies. The method is based on the Empirical Green Function (EGF) deconvolution method. The main advantage of our method is that it is conceptually simple and fast (near real-time speeds) and can be applied to any active seismic area. Results show heterogeneity of rupture directivity along the activated fault system with a complex pattern even if most of the studied events have similar focal mechanisms. However, homogeneous pattern in rupture directivity is observed along the activated fault system and the preferred trend of the rupture propagation is in large part controlled by pre-existing structural discontinuities, i.e., the NW-SE faults. Therefore, we suggest that pre-existing structural discontinuities may control the directivity in the way that such discontinuities represent weakness zone, i.e., zones affected by a bi-material fault interface. We also discuss the possible role of fluids as a cause of bi-material and propose an interpretation of our results based on the role of fluids in the studied sequence as reported in literature. Furthermore, we investigated a possible control of rupture directivity on the location of immediate aftershocks. We calculated the cumulative number of events, which occurred in the forward, backward and orthogonal rupture propagation direction, before and after the occurrence of events, and found that for the analyzed events immediate seismicity mainly appears to be correlated with rupture directivity along the pre-existing structural discontinuities.

description: We study the interaction of surface acoustic waves (SAWs) with the contact-based, axial vibrational resonance of 1 μm silica microspheres forming a two-dimensional granular crystal adhered to a substrate. The laser-induced transient grating technique is used to excite SAWs and measure their dispersion. The measured dispersion curves exhibit "avoided crossing" behavior due to the hybridization of the SAWs with the microsphere resonance. We compare the measured dispersion curves with those predicted by our analytical model, and find excellent agreement. The approach presented can be used to study the contact mechanics and adhesion of micro- and nanoparticles as well as the dynamics of microscale granular crystals.

description: Symmetric, elegantly entangled structures are a curious mathematical construction that has found their way into the heart of the chemistry lab and the toolbox of constructive geometry. Of particular interest are those structures—knots, links and weavings—which are composed locally of simple twisted strands and are globally symmetric. This paper considers the symmetric tangling of multiple 2-periodic honeycomb networks. We do this using a constructive methodology borrowing elements of graph theory, low-dimensional topology and geometry. The result is a wide-ranging enumeration of symmetric tangled honeycomb networks, providing a foundation for their exploration in both the chemistry lab and the geometers toolbox.

Brune stress drop, fault slip distribution and high frequency radiation during the 2016-2018 Amatrice-Visso-Norcia seismic sequence
Creators: name: Abercrombie Rachel, E.
name: Calderoni Giovanna
Publisher: name: Zenodo
Year: 2021

description: The predominantly normal-faulting sequence of earthquakes in the Appenines of central Italy during 2016-2018 included nine Mw > 5 earthquakes. Multiple researchers (e.g., Bindi et al., 2020; Morasca et al., 2019) have estimated Brune-style stress drops for earthquakes in this sequence, using different methods, providing an opportunity to compare systematic and random variability. In addition, Tinti et al. (2016) and Chiaraluce et al. (2017) calculated finite fault inversions for the three largest earthquakes: 24 August (Amatrice, Mw 6), 26 August (Visso, Mw 5.9) and 30 October (Norcia, Mw 6.3). Thus, we can compare estimates of Brune stress drop with the slip distribution (and its predicted stress release), including relative estimates for the similar-sized Amatrice and Visso earthquakes. We use two different approaches to calculate the source spectra, corner frequency, and Brune stress drop of 30 of the larger events. One involves correcting the observed amplitudes for independently calculated path and site terms. The other uses the empirical Green’s function (EGF) approach, in which the spectral ratio between target and EGF events yields the source spectrum of the target event. We compare our results with those from previous published studies using spectral approaches to calculate the Brune stress drop. The inter-study variation is significantly larger than the standard errors produced by any single study, and the (apparent?) magnitude dependence varies. All approaches find that the M6 Amatrice earthquake had a higher stress drop than the similar-sized M5.9 Visso earthquake. In contrast, the finite fault inversions of these two earthquakes (Chiaraluce et al., 2017) found that the Visso earthquake had the larger region of concentrated, higher slip, whereas the Amatrice earthquake had multiple, lower slip, sub-events. The spectra of the moment-rate functions are consistent with the spectral analyses; the spectrum of the Amatrice earthquake contains more high frequency energy than that of the Visso earthquake. This comparison of two similar-sized earthquakes suggests that consistent measurement of a higher corner frequency and Brune stress drop indicates greater high-frequency ground motion, but may correspond to greater rupture complexity rather than higher stress drop (and higher slip).
QUANTITATIVE ANALYSES AND EMPIRICAL TESTS OF PERCEPTUAL THEORIES OF THE BLACK HOLE ILLUSION

description: The Black Hole Illusion (BHI) is a nighttime aviation landing illusion where pilots overestimate their descent angle. The BHI occurs when only the outline of the runway is visible to pilots, usually at night with little illumination of the environment. This illusion is dangerous, as it causes pilots to perceive themselves at a high descent angle; and they compensate by flying lower, resulting in a possible crash into the ground or obstacles before the runway. A common interpretation of the BHI is that it represents a perceptual illusion, where the descent angle is misperceived. We quantitatively analyzed two different perceptual theories that predict pilots perceived descent angle during the BHI experience; and we also quantitatively analyzed another perceptual theory to apply during nighttime approaches to alleviate the disorientation experienced from the BHI. Of the first two theories, Perrone's algorithm (Perrone, 1983) predicts that the magnitude of the illusion should vary with runway width/length in nighttime conditions, compared to no illusion and no effect of runway width/length in daylight conditions. On the other hand, the eye-level algorithm (adapted from the work in Galanis, Jennings, and Beckett (1998) and Robinson, Williams, and Biggs (2020)) predicts that there should be no effect of runway width/length in either nighttime or daylight conditions. The last algorithm, the focus of expansion algorithm (adapted from the theory of Gibson (1950) and Gibson (1966)), details a way that pilots can obtain the landing position of their aircraft without estimating their angle of descent, thereby alleviating possible disorientation experienced during nighttime approaches. Additionally, we conducted three empirical studies: The first two aimed at testing Perrone's algorithm and the eye-level algorithm; and the third aimed at testing the focus of expansion algorithm. Across the first two empirical studies, we did demonstrate a BHI for the nighttime evaluations of descent angle; but the data did not support either algorithm. In the third empirical study, the data did not support the focus of expansion algorithm; however, we found that participants were more accurate with estimating the aircraft's landing position when the landing position was closer to the beginning of the runway. Overall, we conclude that the BHI may reflect general disorientation in conditions with limited information.

description: Let T be a measurable transformation of a probability space $(E,\mathcal {E},π)$, preserving the measure π. Let X be a random variable with law π. Call K(\cdot, \cdot) a regular version of the conditional law of X given T(X). Fix $B\in \mathcal {E}$. We first prove that if B is reachable from π-almost every point for a Markov chain of kernel K, then the T-orbit of π-almost every point X visits B. We then apply this result to the Lévy transform, which transforms the Brownian motion W into the Brownian motion |W| - L, where L is the local time at 0 of W. This allows us to get a new proof of Malric's theorem which states that the orbit under the Lévy transform of almost every path is dense in the Wiener space for the topology of uniform convergence on compact sets.

insulin resistance
metabolic syndrome

description: PCOS (polycystic ovarian syndrome) is a prevalent hormonal illness that affects women all over the world. Although the specific cause of PCOS is unknown, obesity, hyperandrogenism, and insulin resistance have all been considered as important triggering factors. Menstrual irregularities, acne, hirsutism, a predisposition toward central obesity, and insulin resistance symptoms are all signs of PCOS. Reduced body weight, androgen-lowering drugs, insulin-lowering drugs, and surgical treatments are all used to address the clinical symptoms and consequences of PCOS. The aim of this chapter is to shed light on PCOS regarding its prevalence, etiological factors, pathogenesis, clinical manifestations, methods of diagnosis, lines of management and prognosis in view of the recent trends.

description: We investigate the entanglement properties of the equilibrium and nonequilibrium quantum dynamics of 2D and 3D Fermi gases, by computing entanglement entropies of extended space regions, which generally show multiplicative logarithmic corrections to the leading power-law behaviors, corresponding to the logarithmic corrections to the area law. We consider 2D and 3D Fermi gases of N particles constrained within a limited space region, for example by a hard-wall trap, at equilibrium at T=0, i.e. in their ground state, and compute the first few terms of the asymptotic large-N behaviors of entanglement entropies and particle fluctuations of subsystems with some convenient geometries, which allow us to significantly extend their computation. Then, we consider their nonequilibrium dynamics after instantaneously dropping the hard-wall trap, which allows the gas to expand freely. We compute the time dependence of the von Neumann entanglement entropy of space regions around the original trap. We show that at small time it is characterized by the relation $S \approx π^2 V/3$ with the particle variance, and multiplicative logarithmic corrections to the leading power law, i.e. $S \sim t^{1-d}\ln(1/t)$.

subject: FOS: Physical sciences

description: Several advances have extended the power and versatility of coherent state theory to the extent that it has become a vital tool in the representation theory of Lie groups and their Lie algebras. Representative applications are reviewed and some new developments are introduced. The examples given are chosen to illustrate special features of the scalar and vector coherent state constructions and how they work in practical situations. Comparisons are made with Mackey's theory of induced representations. For simplicity, we focus on square integrable (discrete series) unitary representations although many of the techniques apply more generally, with minor adjustment.

Abstract
Sleep passed the evolutionary siege in all studied animal species, notwithstanding its apparent unproductivity (lower reactivity to external dangers, no feeding, no mating). In humans, the time spent in sleep is higher in younger individuals, precisely when learning is faster. Another element to be considered is that, thanks to an evolutionary history that spanned hundreds of millions of years and selected among countless individuals, the inter-areal and local connectome captures the priors necessary to optimize the flow and combination of internal hypotheses and sensorial evidence. 
At the cellular level, optimal combination of contextual information and local computation is provided by the apical amplification principle, active during wakefulness. Deep-sleep (NREM) and REM sleep are characterized in mammals by pyramidal neurons changing to a different management of apical signals, namely apical-isolation and apical-drive.The cognitive and energetic functions of sleep and its relations with awake performance have beeninvestigated by INFN in spiking models, engaged in learning and sleep cycles, that will be presented in this seminar. Also, preliminar information about a next generation of neural models supporting apical mechanisms will be presented.

Social and feeding behavior of dairy calves in automated milk feeder systems
Creators: name: Gonzalez, Maria Elisa Montes
Publisher: name: Purdue University Graduate School
Year: 2022
Subjects: Animal management

description: Calves raised in automated milk feeder (AMF) systems benefit from social interaction and having access to large amounts of milk, which they can consume in multiple small meals. Additionally, these systems record longitudinal feeding behavior measurements on each calf. However, if group size, composition, and disease detection are not optimal, the health and performance of calves can be compromised. The analysis of AMF data can provide information that may allow for improved disease detection and group management to maximize health and welfare of pre-weaned dairy calves. A proper understanding of the data generated by AMF and its context are essential to derive meaningful information about health status and group dynamics of dairy calves. Because the goal is that farmers can use this information to support decisions, six years of historical data from a commercial dairy farm were first collected, described, and stored in a research data ecosystem and then used to evaluate feeding and social behavior of calves. The first chapter evaluates the effect of environmental and biological factors on the feeding behavior of 9,737 calves. The results showed that reductions in milk consumption and drinking speed preceded the detection of bovine respiratory disease using farm protocols. In addition to health status, temperature humidity index, birth weight, and parity of the dam also influenced milk consumption and drinking speed. Therefore, including data on the traits of the individuals and the conditions of their environment can improve predictive models for sickness detection and performance assessment. The second chapter evaluates the use of AMF records and social network analysis. Interactions that occur at the autofeeder from 254 calves in five groups were used to rank individual animals and assess the groups’ stability. Enrollment order was associated with dominance rating, based on feeder displacements. Birth weight, however, had no influence on dominance rating. Social network analysis showed that although displacements are not constant over time, calves did not displace every other calf in their group, indicating some selectivity. This study demonstrates the possibility of using longitudinal data from precision technology to assess group dynamics.
