description: We present a method for the direct evaluation of the difference between the free energies of two crystalline structures, of different symmetry. The method rests on a Monte Carlo procedure which allows one to sample along a path, through atomic-displacement-space, leading from one structure to the other by way of an intervening transformation that switches one set of lattice vectors for another. The configurations of both structures can thus be sampled within a single Monte Carlo process, and the difference between their free energies evaluated directly from the ratio of the measured probabilities of each. The method is used to determine the difference between the free energies of the fcc and hcp crystalline phases of a system of hard spheres.

description: The friction dynamics in the boundary layer of a brake system is closely linked with the growth and the destruction of typical structures on the brake pad. These processes are caused by an interaction of friction and wear and determine the (as well measured) time-dependence of global parameters, such as the friction coefficient μ or the temperature. Based on the simulation with a set of differential equations, this equilibrium of flow has also already been described with a Cellular-Automaton-discretisation. This paper will show new results and fundamental conclusions with respect to the surface topography dynamics and the friction behavior of a brake system.

description: In this paper, we have analyzed the performance-complexity tradeoff of {a selective} likelihood ascent search (LAS) algorithm initialized by a linear detector, such as matched filtering (MF), zero forcing (ZF) and minimum mean square error (MMSE), {and considering an optimization factor $ρ$ from the bit flipping rule}. The scenario is the uplink of a massive MIMO (M-MIMO) system, and the {analysis has }been developed by means of computer simulations. With the increasing number of base station (BS) antennas, the classical detectors become inefficient. Therefore, the LAS is employed for performance-complexity tradeoff improvement. Using an adjustable optimized threshold on the bit flip rule of LAS, much better solutions have been achieved in terms of BER with no further complexity increment, indicating that there is an optimal threshold for each scenario. Considering a $32\times32$ antennas scenario, {the large-scale MIMO system equipped with the proposed LAS detector with} factor $ρ$ = 0.8 {requires} 5 dB less {in terms of SNR than the conventional LAS of the} literature ($ρ$ = 1.0) to achieve the same bit error rate of $10^{-3}$.

description: The massless conformally coupled scalar field is characterized by the so-called "new improved stress-energy tensor", which is capable of classically violating the null energy condition. When coupled to Einstein gravity we find a three-parameter class of exact solutions. These exact solutions include the Schwarzschild geometry, assorted naked singularities, and a large class of traversable wormholes.

description: We study the influence of many-particle interaction in a system which, in the single particle case, exhibits a metal-insulator transition induced by a finite amount of onsite pontential fluctuations. Thereby, we consider the problem of interacting particles in the one-dimensional quasiperiodic Aubry-Andre chain. We employ the density-matrix renormalization scheme to investigate the finite particle density situation. In the case of incommensurate densities, the expected transition from the single-particle analysis is reproduced. Generally speaking, interaction does not alter the incommensurate transition. For commensurate densities, we map out the entire phase diagram and find that the transition into a metallic state occurs for attractive interactions and infinite small fluctuations -- in contrast to the case of incommensurate densities. Our results for commensurate densities also show agreement with a recent analytic renormalization group approach.

description: The dynamics of brake systems is determined by the growth and destruction of characteristic hard, smooth and friction-intensive structures (“patches”) on brake pads. These mesoscopic structures carry a main part of the friction power and protect the softer matrix material below from wear. This equilibrium of flow is therefore correlated with the wear rate and the friction coefficient μ which has to be interpreted as a dynamic process-parameter, as recent works show. In this paper we show, how the existing two-dimensional Cellular Automaton model of the boundary layer can be extended in order to describe the topography in three dimensions. This is realized by introducing further inner system variables. With the help of measurements for pads having run under different pressure- and temperature conditions basic interactions between the external load and the surface topography can be seen. This works presents how, based on these measurements and the Cellular-Automata simulations, conclusions towards the global friction- and wear behavior of brake systems can be made.

description: We present the first results of our pilot study of 8 photometrically selected Lyman continuum (LyC) emitting galaxy candidates from the COSMOS field and focus on their optical emission line ratios. Observations were performed in the H and K bands using the Multi-Object Spectrometer for Infra-Red Exploration (MOSFIRE) instrument at the Keck Observatory, targeting the [OII], H$β$, and [OIII] emission lines. We find that photometrically selected LyC emitting galaxy candidates have high ionization parameters, based on their high [OIII]/[OII] ratios (O32), with an average ratio for our sample of 2.5$\pm$0.2. Preliminary results of our companion Low Resolution Imaging Spectrometer (LRIS) observations, targeting LyC and Ly$α$, show that those galaxies with the largest O32 are typically found to also be Ly$α$ emitters. High O32 galaxies are also found to have tentative non-zero LyC escape fractions ($f_{esc}(LyC)$) based on $u$ band photometric detections. These results are consistent with samples of highly ionized galaxies, including confirmed LyC emitting galaxies from the literature. We also perform a detailed comparison between the observed emission line ratios and simulated line ratios from density bounded H$_{\textrm{II}}$ regions modeled using the photoionization code MAPPINGS V. Estimates of $f_{esc}(LyC)$ for our sample fall in the range from 0.0-0.23 and suggest possible tension with published correlations between O32 and $f_{esc}(LyC)$, adding weight to dichotomy of arguments in the literature. We highlight the possible effects of clumpy geometry and mergers that may account for such tension.

Η Ελλάδα, λόγω της γεωγραφικής της θέσης, των κλιματικών της συνθηκών και του ποικιλόμορφου ανάγλυφου, απολαμβάνει ιδανικές συνθήκες για την αξιοποίηση της αιολικής ενέργειας. Ωστόσο, εγείρει προβληματισμό η βιωσιμότητα από την πιθανή ανάπτυξη Υπεράκτιων Αιολικών Πάρκων (ΥΑΠ).
Στο πλαίσιο της παρούσας εργασίας αξιολογείται η επίδραση ενός υποθετικού έργου ΥΑΠ στο νησί της Πάρου μέσω έρευνας με τη χρήση ερωτηματολογίου και αποδέκτες τους ενδιαφερόμενους φορείς του εγχειρήματος. Το ερωτηματολόγιο δομήθηκε αξιοποιώντας πληροφορίες για τα οφέλη και τις προκλήσεις σε υφιστάμενα έργα ΥΑΠ και γενικότερα ΑΠΕ και επιλέχθηκε να εκτείνεται στους τρεις πυλώνες της αειφορίας (Περιβάλλον, Οικονομία, Κοινωνία), αξιολογώντας έτσι καλύτερα και τις κοινωνικοπολιτισμικές εκτάσεις ενός περιβαλλοντικού εγχειρήματος.
Η ανάλυση των αποτελεσμάτων οδήγησε σε ενδιαφέροντα συμπεράσματα για το πως το ίδιο εγχείρημα μπορεί να αξιολογηθεί διαφορετικά από τον κάθε φορέα, κρίνοντας από το συλλογικό συμφέρον, το προσωπικό όφελος, τις ανησυχίες από την απόκλιση σε κοινωνικές και περιβαλλοντικές νόρμες αλλά και τις νέες προοπτικές που κάθε καινοτόμα ενέργεια δύναται να προσφέρει.

description: The energy transition, especially in recent years, has emerged as a key global priority, with offshore wind farms playing a key role in promoting sustainable solutions and reducing dependence on fossil fuels. Greece, due to its geographical location, climatic conditions and diverse topography, enjoys ideal conditions for the exploitation of wind energy. However, the viability of the possible development of offshore wind farms raises concerns.
In the context of this paper, the impact of a hypothetical OWF project on the island of Paros is evaluated through a survey using a questionnaire and addressed to the stakeholders of the project. The questionnaire was structured by utilizing information on the benefits and challenges in existing OWF projects and RES in general and was chosen to span the three pillars of sustainability (Environment, Economy, Society), thus better assessing the socio-cultural dimensions of an environmental project.
The analysis of the results led to interesting conclusions on how the same project can be evaluated differently by each actor, judged by collective interest, personal benefit, concerns from deviation from social and environmental norms and the new perspectives that each innovative action can offer.

description: BackgroundOnline sources covering variety of topics including health related information are increasing at a tremendous speed. It is important that users are aware of the authenticity and credibility of these information shared on social media and online sources. However, manually apprising the credibility of these online information is not feasible due its sheer volume; therefore, it is important to find methods to estimate the credibility of these information using automatic methods. AimThe aim of this thesis is to develop machine learning models to estimate the credibility of health news in social media.MethodsWe have downloaded the data from the public repository (Fake Health) that contains two separate datasets, Health Release and Health Story. Both are Web pages that were shared on Twitter. These Web pages were manually labelled against a 10-point checklist. The dataset also, included tweets, retweets, and replies in which these Web pages were shared. We used these manually labelled data to evaluate the performance of our classifiers. We used H2O Python library to evaluate a set of classifiers and used Accuracy, AUC, Specificity and Sensitivity to compare the classifiers. Additionally, we also measured the engagement of the Web pages shared on social media through the number of tweets, retweets, replies, likes and potential exposure.ResultsThe highest performing classifier has 93% accuracy for Health Release and 87% for Health Story. AUC for highest performing classifier was 87% for Health Release and 90% for Health Story. Specificity and sensitivity were 95%, 85% in Health Release and 94%, 89% in Health Story, respectively. We found that low credible Web pages were posted more frequently on Twitter than high credible Web pages.ConclusionThe results indicate that it is possible to estimate the credibility of Web pages automatically using machine learning based methods. Users tend to disseminate low credibility Web pages more often than high credibility Web pages.
Plasma instability and amplification of electromagnetic waves in low-dimensional electron systems

Publisher: name: arXiv

description: A general electrodynamic theory of a grating coupled two dimensional electron system (2DES) is developed. The 2DES is treated quantum mechanically, the grating is considered as a periodic system of thin metal strips or as an array of quantum wires, and the interaction of collective (plasma) excitations in the system with electromagnetic field is treated within the classical electrodynamics. It is assumed that a dc current flows in the 2DES. We consider a propagation of an electromagnetic wave through the structure, and obtain analytic dependencies of the transmission, reflection, absorption and emission coefficients on the frequency of light, drift velocity of 2D electrons, and other physical and geometrical parameters of the system. If the drift velocity of 2D electrons exceeds a threshold value, a current-driven plasma instability is developed in the system, and an incident far infrared radiation is amplified. We show that in the structure with a quantum wire grating the threshold velocity of the amplification can be essentially reduced, as compared to the commonly employed metal grating, down to experimentally achievable values. Physically this is due to a considerable enhancement of the grating coupler efficiency because of the resonant interaction of plasma modes in the 2DES and in the grating. We show that tunable far infrared emitters, amplifiers and generators can thus be created at realistic parameters of modern semiconductor heterostructures.

description: ABSTRACT

Background: Globally 2.4 million children died in the first month of life in 2020. There are approximately 6700newborn deaths every day, amounting to 47% of all child deaths under the age of 5 years, up from 40% in 1990.

The world has made substantial progress in child survival since 1990. Globally, the number of neonatal deaths declined from 5 million in 1990 to 2.4 million in 2020. However, the decline in neonatal mortality from 1990 to 2020 has been slower than that of post-neonatal under-5 mortality.

Saharan Africa had the highest neonatal mortality rate in 2020 at 27 (25–••32) deaths per 1000 live births, followed bycentral and southern Asia with 23 (21–••25) deaths per 1000 live births.

Objectives: To contribute reduction of risk factors associated with neonatal mortality rate in Somalia specially Banadir hospital.

Method: The study design of this study was conducted in descriptive quantitative cross- sectional study design fordata collection about to determine prevalence risk factors of neonatal Mortality rate.

Results: Prevalence of neonatal mortality rate 27(33.8%) died during NICU admission, compared to those with improved crucial care in NICU that was most of the respondents 53(66.3%) improved with good outcomes.

According to the following sequence, the most factors that caused the neonatal mortality in the hospital Banadir were 17(21.25%) neonatal sepsis, 23(28.75%) prematurity, 7(8.75%) sepsis, 11(13.75%) Respiratory distress syndrome, 19(23.75%) asphyxia, 9(11.25%) with jaundice, 2(2.5%) with birth injury, 1(1.25%) with congenital anomaly and the 2(2.25%) with other conditions, instead of 9(11.25%) was neonatal jaundice, while 3(3.75%) of neonates wereRespiratory distress syndrome, however the 4(5.0%) were neonatal anaemia, while 13(16.25%) had seizure, furthermore the 23(28.75%) of neonates had MAS, while the 3(3.75%) had TORCH infections, lastly 5(6.25%) wereother conditions

56(70%) of the study participants' mothers had no previous history of neonatal death in the past gestation, while24(30%) of the mothers were said to have a previous history of neonatal death in the previous gestational.

In contrast to ordinary sphere compactifications, the above setup can lead to the degeneracy of and the sharp localizations of the linearly independent lowest KK modes, depending on the number of branes and their tensions. Moreover, it can naturally accommodate CP violation in Yukawa interactions.

The optical conductivity function was obtained via Kramers-Kronig analysis. We observed a dirty metal-like behavior at room temperature and the opening of a gap of 70 meV at low temperature. The results of a group theoretical analysis of the lattice vibrational modes are presented and compared to the experimental data. Of the five optical phonons expected for this material only four have been observed in the far-infrared region.

description: Deterministic simulations with the Reserve Bank of New Zealand’s core FPS model show how New Zealand’s broad macroeconomic environment might have evolved over the 1990s, if a US nominal yield curve and US TWI exchange rate movements under a common currency arrangement had been experienced. Relatively looser monetary conditions would have prevailed, and led to modest short-run output gains, greater excess demand pressures, noticeably higher CPI inflation rates over the whole of the 1990s, and less favourable trade balance outcomes, especially for the late 1990s. These macroeconomic outcomes are overall less favourable than those obtained from simulating the equivalent Australian monetary conditions.

description: A global quantum repeater network involving satellite-based links is likely to have advantages over fiber-based networks in terms of long-distance communication, since the photon losses in free space scale only polynomially with the distance -- compared to the exponential losses in optical fibers. To simulate the performance of such networks, we have introduced a scheme of large-scale event-based Monte Carlo simulation of quantum repeaters with multiple memories that can faithfully represent loss and imperfections in these memories. In this work, we identify the quantum key distribution rates achievable in various satellite and ground station geometries for feasible experimental parameters. The power and flexibility of the simulation toolbox allows us to explore various strategies and parameters, some of which only arise in these more complex, multi-satellite repeater scenarios. As a primary result, we conclude that key rates in the kHz range are reasonably attainable for intercontinental quantum communication with three satellites, only one of which carries a quantum memory.

description: Microplastics (MP) constitute a widespread contaminant all over the globe. Rivers and wastewater treatment plants (WWTP) transport annually several million tons of MP into freshwaters, estuaries and oceans, where they provide increasing artificial surfaces for microbial colonization. As knowledge on MP-attached communities is insufficient for brackish ecosystems, we conducted exposure experiments in the coastal Baltic Sea, an in-flowing river and a WWTP within the drainage basin. While reporting on prokaryotic and fungal communities from the same set-up previously, we focus here on the entire eukaryotic communities. Using high-throughput 18S rRNA gene sequencing, we analyzed the eukaryotes colonizing on two types of MP, polyethylene and polystyrene, and compared them to the ones in the surrounding water and on a natural surface (wood). More than 500 different taxa across almost all kingdoms of the eukaryotic tree of life were identified on MP, dominated by Alveolata, Metazoa, and Chloroplastida. The eukaryotic community composition on MP was significantly distinct from wood and the surrounding water, with overall lower diversity and the potentially harmful dinoflagellate Pfiesteria being enriched on MP. Co-occurrence networks, which include prokaryotic and eukaryotic taxa, hint at possibilities for dynamic microbial interactions on MP. This first report on total eukaryotic communities on MP in brackish environments highlights the complexity of MP-associated biofilms, potentially leading to altered microbial activities and hence changes in ecosystem functions.

description: We present a detailed numerical analysis of the low energy excitation spectrum of a frustrated and dimerized spin $S=1/2$ Heisenberg chain. In particular, we show that in the commensurate spin--Peierls phase the ratio of the singlet and triplet excitation gap is a universal function which depends on the frustration parameter only. We identify the conditions for which a second elementary triplet branch in the excitation spectrum splits from the continuum. We compare our results with predictions from the continuum limit field theory . We discuss the relevance of our data in connection with recent experiments on $CuGeO_{3}$, $NaV_2O_5$, and $(VO)_2P_2O_7$.

description: A large part of biodiversity theory is driven by the basic question of what allows species to coexist in spite of a confined number of niches. A substantial theoretical background to this question is provided by modern coexistence theory (MCT), which rests on mathematical approaches of invasion analysis to categorize underlying mechanisms into factors that reduce either niche overlap (stabilizing mechanisms) or the average fitness differences of species (equalizing mechanisms). While MCT has inspired biodiversity theory in the search for these underlying mechanisms, we feel that the strong focus on coexistence causes a bias toward the most abundant species and neglects the plethora of species that are less abundant and often show high local turnover. Given the more stochastic nature of their occurrence, we advocate a complementary cross-level approach that links individuals, small populations, and communities and explicitly takes into account (1) a more complete inclusion of environmental and demographic stochasticity affecting small populations, (2) intraspecific trait variation and behavioral plasticity, and (3) local heterogeneities, interactions, and feedbacks. Focusing on mechanisms that drive the temporary coviability of species rather than infinite coexistence, we suggest a new approach that could be dubbed coviability analysis (CVA). From a modeling perspective, CVA builds on the merged approaches of individual-based modeling and population viability analysis but extends them to the community level. From an empirical viewpoint, CVA calls for a stronger integration of spatiotemporal data on variability and noise, changing drivers, and interactions at the level of individuals. The resulting large volumes of data from multiple sources could be strongly supported by novel techniques tailored to the discovery of complex patterns in high-dimensional data. By complementing MCT through a stronger focus on the coviability of less common species, this approach can help make modern biodiversity theory more comprehensive, predictive, and relevant for applications.

description: Any two infinite-dimensional (separable) Hilbert spaces are unitarily isomorphic. The sets of all their self-adjoint operators are also therefore unitarily equivalent. Thus if all self-adjoint operators can be observed, and if there is no further major axiom in quantum physics than those formulated for example in Dirac's `Quantum Mechanics', then a quantum physicist would not be able to tell a torus from a hole in the ground. We argue that there are indeed such axioms involving observables with smooth time evolution: they contain commutative subalgebras from which the spatial slice of spacetime with its topology (and with further refinements of the axiom, its $C^K-$ and $C^\infty-$ structures) can be reconstructed using Gel'fand - Naimark theory and its extensions. Classical topology is an attribute of only certain quantum observables for these axioms, the spatial slice emergent from quantum physics getting progressively less differentiable with increasingly higher excitations of energy and eventually altogether ceasing to exist. After formulating these axioms, we apply them to show the possibility of topology change and to discuss quantized fuzzy topologies. Fundamental issues concerning the role of time in quantum physics are also addressed.

Nucleation of the crystalline phase of proteins in the presence of semidilute non-adsorbing polymer

description: Starting from a protein solution which is metastable with respect to the crystalline phase, the effect of adding semidilute non-adsorbing polymer is considered. It is found to increase the chemical potential of the protein by a few tenths of kT, which may be enough to lower the barrier to nucleation of the crystalline phase by enough to allow crystallisation. It is also shown that assuming that the polymer induces a pairwise additive attraction leads to qualitatively incorrect results.

description: Studying experimental data obtained at ITEP [1] on neutron production in interactions of protons with various nuclei in the energy range from 747 MeV up to 8.1 GeV, we have found that slow neutron spectra have scaling and asymptotic properties [2]. The spectra weakly depend on the collision energy at momenta of projectile protons larger than 5 - 6 GeV/c. These properties are taken into account in the Geant4 Fritiof (FTF) model. The improved FTF model describes as well as the Geant4 Bertini model the experimental data on neutron production by 1.2 GeV and 1.6 GeV protons on targets (Fe, Pb) [3] and by 3.0 GeV protons on various targets (Al, Fe, Pb) [4]. For neutron production in antiproton-nucleus interactions, it was demonstrated that the FTF results are in a satisfactory agreement with experimental data of the LEAR collaboration [5]. The FTF model gives promising results for neutron production in nucleus - nucleus interactions at projectile energy 1 - 2 GeV per nucleon [6]. The observed properties allow one to predict neutron yields in the nucleus-nucleus interactions at high and very high energies. Predictions for the NICA/MPD experiment at JINR are presented.

description: Fractional quantum Hall effect energy gaps have been measured in GaAs/GaAlAs heterojunctions as a function of Zeeman energy, which is varied by applying hydrostatic pressure up to 20 kbar. The gap at v=1/3 decreases with pressure until the g-factor changes sign when it again increases. The behavior is similar to that seen at v=1 and shows that excitations from the 1/3 ground state can be spin-like in character. At small Zeeman energy, the excitation appears to consist of 3 spins and may be interpreted as a small composite skyrmion.

Quantum transport through the edge states of Zigzag phosphorene nanoribbons in presence of a single point defect: analytic Green's function method

description: Zigzag phosphorene nanoribbons have quasi-flat band edge modes entirely detached from the bulk states. We analytically study the electronic transport through such edge states in the presence of a localized defect for semi-infinite and finite ribbons. Using the tight-binding model, we derive analytical expressions for the Green's function and transmission amplitude of both pristine and defective nanoribbons. We find that the transmission of both semi-infinite and finite ribbons is sensitive to the location of a single impurity defect with respect to the edge. By the presence of an impurity on the outermost edge site of the ribbon, the transmission through the edge channel, similar to a one-dimensional chain, strongly suppresses for the entire energy spectrum of the quasi-flat band. In contrast, the transmission of low-energy $(E\approx 0)$ states, is robust as the impurity is moved one position far away from the edge on the same sub-lattice. The analytical calculations are also complemented by exact numerical transport computations using the Landauer approach.
Material transport in the left ventricle with aortic valve regurgitation

description: This experimental in vitro work investigates material transport properties in a model left ventricle in the case of aortic regurgitation, a valvular disease characterized by a leaking aortic valve and consequently double-jet filling within the elastic left ventricular geometry. This study suggests that material transport phenomena are strongly determined by the motion of the counterrotating vortices driven by the regurgitant aortic and mitral jets. The overall particle residence time appears to be significantly longer with moderate aortic regurgitation, attributed to the dynamics resulting from the timing between the onset of the two jets. Increasing regurgitation severity is shown to be associated with higher frequencies in the time-frequency spectra of the velocity signals at various points in the flow, suggesting nonlaminar mixing past moderate regurgitation. Additionally, a large part of the regurgitant inflow is retained for at least one cardiac cycle. Such an increase in particle residence time accompanied by the occurrence and persistence of a number of attracting Lagrangian coherent structures presents favorable conditions and locations for activated platelets to agglomerate within the left ventricle, potentially posing an additional risk factor for patients with aortic regurgitation.
On the nature of black hole entropy

description: I argue that black hole entropy counts only those states of a black hole that can influence the outside, and attempt (with only partial success) to defend this claim against various objections, all but one coming from string theory. Implications for the nature of the Bekenstein bound are discussed, and in particular the case for a holographic principle is challenged. Finally, a generalization of black hole thermodynamics to "partial event horizons" in general spacetimes without black holes is proposed.
