description: This work presents an experimental evaluation of the detection performance of eight different algorithms for anomaly detection on the Controller Area Network (CAN) bus of modern vehicles based on the analysis of the timing or frequency of CAN messages. This work solves the current limitations of related scientific literature, that is based on private dataset, lacks of open implementations, and detailed description of the detection algorithms. These drawback prevent the reproducibility of published results, and makes it impossible to compare a novel proposal against related work, thus hindering the advancement of science. This paper solves these issues by publicly releasing implementations, labeled datasets and by describing an unbiased experimental comparisons.

description: Among iron based superconductors, the layered iron chalcogenide Fe(Te1-xSex) is structurally the simplest and has attracted considerable attentions. It has been speculated from bulk studies that nanoscale inhomogeneous superconductivity may inherently exist in this system. However, this has not been directly observed from nanoscale transport measurements. In this work, through simple micromechanical exfoliation and high precision low-energy ion milling thinning, we prepared Fe(Te0.5Se0.5) nano-flake with various thickness and systematically studied the correlation between the thickness and superconducting phase transition. Our result revealed a systematic evolution of superconducting transition with thickness. When the thickness of Fe(Te0.5Se0.5) flake is reduced down to 12nm, i.e. the characteristic length of Te/Se fluctuation, the superconducting current path and the metallicity of normal state in Fe(Te0.5Se0.5) atomic sheets is suppressed. This observation provides the first direct transport evidence for the nano-scale inhomogeneous nature of superconductivity in Fe(Te1-xSex).
title: Zur Hintergrundmusik im Bekleidungseinzelhandel in Wien am Beispiel der Fashion Stores C&A, H&M und Peek & Cloppenburg
Creators: name: Kolb, Anna
Year: 2023

description: Die vorliegende Arbeit beschäftigt sich mit dem Thema der Hintergrundmusik im Bekleidungseinzelhandel. Diese wurde am Beispiel der drei beliebtesten Fashion Stores Österreichs untersucht, nämlich der internationalen Modeketten C&A, H&M und Peek & Cloppenburg. Die Forschungsfragen lauten: Welche Art von Musik wird in den drei Fashion Stores eingesetzt? Wie wird die Musik von Mitgliedern der Zielgruppe rezipiert? Gibt es für sie wahrnehmbare Unterschiede zwischen den drei untersuchten Fashion Stores? Um diesen Fragestellungen nachzugehen, wurde eine Feldstudie auf einer der wichtigsten Wiener Einkaufsstraßen durchgeführt und im Anschluss wurden zwei Fokusgruppendiskussionen geleitet. In der Feldstudie wurden 17 Fashion Stores besucht und ihre Mitarbeiter:innen zur jeweiligen In-Store-Playlist befragt, um einen Überblick zu bekommen, wie die Musikgestaltung in diesen Geschäften gehandhabt wird. Des Weiteren wurden die drei Filialen von C&A, H&M und Peek & Cloppenburg besucht, um Ausschnitte aus ihren In-Store-Playlists zu ermitteln. Die Fokusgruppenteilnehmerinnen wurden zu ihrer Haltung zu Hintergrundmusik befragt, sowie zu ihrer Wahrnehmung der Songausschnitte der drei Bekleidungsgeschäfte. Die Playlists von C&A, H&M und Peek & Cloppenburg wurden unterschiedlich beurteilt, im Allgemeinen gefiel jene von H&M durch eine Mischung aktueller Hits und älterer Songs am besten. In jedem Fall wurde festgestellt, dass bekannte und gemochte Titel die Stimmung verbessern und damit auf das Image des Stores abfärben können. Die Urteile der Diskutantinnen und die Beobachtungen aus der Feldstudie unterscheiden sich in einigen Punkten von Erkenntnissen aus der Fachliteratur. Insgesamt dürfte die größte positive Wirkung jedenfalls erreicht werden, wenn die In-Store-Musik den persönlichen Geschmack der Zielgruppe trifft.

description: We present, experimentally and theoretically, a scheme for dressed-state electromagnetically induced transparency (EIT) in a three-step cascade system where a four-level system is mapped into an effective three-level system. Theoretical analysis reveals that the scheme provides coherent state control via adiabatic following and provides a generalized protocol for light storage in uniform phase spin-waves that are insensitive to motional dephasing. The three-step driving enables a number of other features including spatial selectivity of the excitation region within the atomic medium, and kick-free and Doppler-free excitation that produces narrow resonances in thermal vapor. As a proof of concept we present an experimental demonstration of the generalized EIT scheme using the $6S_{1/2} \rightarrow 6P_{3/2} \rightarrow 7S_{1/2} \rightarrow 8P_{1/2}$ excitation path in thermal cesium vapor. This technique could be applied to cold and thermal ensembles to enable longer storage times for Rydberg polaritons.

description: This paper presents the assessment of altimetric data from Sentinel-3A satellite operating in Synthetic Aperture Radar (SAR) mode for sea level research studies and applications over the largest archipelagos at Southeast Asia. Both qualitative and quantitative assessments are conducted by analysing the physical shapes of waveforms, comparing with quasi-independent geoidal height data and independent tide gauge measurements. The results identified the percentage of ocean like and non-ocean like waveforms are 91% and 9%, respectively. Off 9% of non-ocean like waveforms, the major class is multi-peak (7%) followed by the quasi-specular waveforms (2%) observed near the coastline (<10 km). Ocean like waveforms typically appear beyond 500 m from the coastline. When comparing with geoidal heights and tide gauge measurements, the performance of sea levels from several retrackers are assessed. The SAMOSA+ retracker outperforms other retrackers (i.e. sub-waveform and modified threshold retrackers with 30%, 20% and 10%). That is, the standard deviation of differences against geoidal heights, and the temporal correlation against tide gauges are superior in most cases. In terms of root mean square error (RMSE), all retrackers are ranging with RMSE <20 cm in all cases. It can be concluded that in general, the SAMOSA+ retracked sea levels are accurate over the complicated regions at the Southeast Asia.

description: We propose a systematic approach for registering cross-source point clouds. The compelling need for cross-source point cloud registration is motivated by the rapid development of a variety of 3D sensing techniques, but many existing registration methods face critical challenges as a result of the large variations in cross-source point clouds. This paper therefore illustrates a novel registration method which successfully aligns two cross-source point clouds in the presence of significant missing data, large variations in point density, scale difference and so on. The robustness of the method is attributed to the extraction of macro and micro structures. Our work has three main contributions: (1) a systematic pipeline to deal with cross-source point cloud registration; (2) a graph construction method to maintain macro and micro structures; (3) a new graph matching method is proposed which considers the global geometric constraint to robustly register these variable graphs. Compared to most of the related methods, the experiments show that the proposed method successfully registers in cross-source datasets, while other methods have difficulty achieving satisfactory results. The proposed method also shows great ability in same-source datasets.

description: Offline reinforcement learning (RL), a technology that offline learns a policy from logged data without the need to interact with online environments, has become a favorable choice in decision-making processes like interactive recommendation. Offline RL faces the value overestimation problem. To address it, existing methods employ conservatism, e.g., by constraining the learned policy to be close to behavior policies or punishing the rarely visited state-action pairs. However, when applying such offline RL to recommendation, it will cause a severe Matthew effect, i.e., the rich get richer and the poor get poorer, by promoting popular items or categories while suppressing the less popular ones. It is a notorious issue that needs to be addressed in practical recommender systems. In this paper, we aim to alleviate the Matthew effect in offline RL-based recommendation. Through theoretical analyses, we find that the conservatism of existing methods fails in pursuing users' long-term satisfaction. It inspires us to add a penalty term to relax the pessimism on states with high entropy of the logging policy and indirectly penalizes actions leading to less diverse states. This leads to the main technical contribution of the work: Debiased model-based Offline RL (DORL) method. Experiments show that DORL not only captures user interests well but also alleviates the Matthew effect. The implementation is available via https://github.com/chongminggao/DORL-codes.

description: We study how the non-Fermi-liquid two-phase state reveals itself in transport properties of high-mobility Si-MOSFETs. We have found features in zero-field transport, magnetotransport, and thermodynamic spin magnetization in a 2D correlated electron system that may be directly related with the two-phase state. The features manifest above a density dependent temperature $T^*$ that represents a novel high-energy scale, apart from the Fermi energy. More specifically, in magnetoconductivity, we found a sharp onset of the novel regime $δσ(B,T) \propto (B/T)^2$ above a density-dependent temperature $T_{\rm kink}(n)$, a high-energy behavior that "mimics" the low-temperature diffusive interaction regime. The zero-field resistivity temperature dependence exhibits an inflection point $T_{\rm infl}(n)$. In thermodynamic magnetization, the weak-field spin susceptibility per electron, $\partial χ/\partial n$ changes sign at $T_{dM/dn}(n)$. All three notable temperatures, $T_{\rm kink}$, $T_{\rm infl}$, and $T_{d M/ d n}$, behave critically $\propto (n-n_c)$, are close to each other, and are intrinsic to high-mobility samples solely, we therefore associate them with an energy scale $T^*$ caused by interactions in the 2DE system.

The spacetime is assumed to admit a homothetic Killing vector. In the collapsing modes, some of the situations indeed hit a singularity, but they are all covered with an apparent horizon. Some peculiar cases are observed where the collapsing body settles to a constant radius at a given value of the radial coordinate.

description: We investigate the effect of variations in beam splitter transmissions and path length differences in the nonlinear sign gate that is used for linear optical quantum computing. We identify two implementations of the gate, and show that the sensitivity to variations in their components differs significantly between them. Therefore, circuits that require a precision implementation may benefit from additional circuit analysis of component variations to identify the most practical implementation. We suggest possible routes to efficient circuit analysis in terms of quantum parameter estimation.

description: The regular hyperbranched polymers (RHPs), also known as Vicsek fractals, are an important family of hyperbranched structures which have attracted a wide spread attention during the past several years. In this paper, we study the first-passage properties for random walks on the RHPs. Firstly, we propose a way to label all the different nodes of the RHPs and derive exact formulas to calculate the mean first-passage time (MFPT) between any two nodes and the mean trapping time (MTT) for any trap node. Then, we compare the trapping efficiency between any two nodes of the RHPs by using the MTT as the measures of trapping efficiency. We find that the central node of the RHPs is the best trapping site and the nodes which are the farthest nodes from the central node are the worst trapping sites. Furthermore, we find that the maximum of the MTT is about $4$ times more than the minimum of the MTT. The result is similar to the results in the recursive fractal scale-free trees and T-fractal, but it is quite different from that in the recursive non-fractal scale-free trees. These results can help understanding the influences of the topological properties and trap location on the trapping efficiency.

description: Die Wohnumgebung außerhalb der eigenen Wohnung beeinflusst die menschliche Entwicklung auf vielfältige Art und Weise. In der vorliegenden Studie wurde der bisher wenig erforschte Zusammenhang zwischen der Walkability der Wohnumgebung, also für die physische Aktivität von Bewohner*innen förderlichen Wohnumgebungsmerkmalen, und dem subjektiven Wohlbefinden von Jugendlichen untersucht. Dabei standen mögliche Effekte dreier verschiedener Walkabilty-Dimensionen (Walkability im engeren Sinn, Ästhetik der Wohnumgebung und Sicherheit in der Wohnumgebung) und eine mögliche Mediation durch physische Aktivität im Zentrum des Forschungsinteresses. Zur Datenerhebung wurden Jugendliche (N = 159) im Alter von 14 bis 18 Jahren im DACH-Raum in einer querschnittlichen Onlinestudie befragt. Die Daten wurden mit Hilfe einer multiplen linearen Regressionsanalyse und eine Mediationsanalyse, jeweils unter Kontrolle zentraler Drittvariablen, analysiert. Es zeigten sich unterschiedliche Ergebnisse für die verschiedenen Walkabililty-Dimensionen. Für Walkability im engeren Sinne ergab sich ein signifikanter, positiver Zusammenhang von geringer Ausprägung, der partiell durch physische Aktivität mediiert wurde. Ästhetik und Sicherheit der Wohnumgebung zeigten keine signifikanten Zusammenhänge mit subjektivem Wohlbefinden. Das Schulklima und die Unterstützung durch die Familie und den Freundeskreis zeigten als Drittvariablen größere positive Effekte auf das subjektive Wohlbefinden als die Walkability-Dimensionen. Insgesamt deuten die Ergebnisse an, dass die Förderung von Walkability im engeren Sinne das subjektive Wohlbefinden jugendlicher Bewohner*innen in geringem Ausmaß steigern kann und dieser Effekt teilweise durch eine erhöhte physische Aktivität zustande kommen kann. Weitere empirische Studien, auch unter Verwendung unterschiedlicher Messmethoden, sind zur Überprüfung der vorliegenden Befunde nötig.

description: Experiments with multiwalled carbon nanotubes and graphite as targets in a source of negative ions with cesium sputtering have shown that nanotubes with nanometer radii and micrometer length can be compared with micrometer size graphite grains to understand the irradiation effects that include the formation, sputtering of carbon clusters and the resulting structural changes. The simultaneous adsorption of cesium on the surface and bombardment by energetic cesium ions is shown to play its role in the cluster formation and sputtering of carbon atoms and clusters and the cesium substituted carbon clusters as anions. Qualitative and quantitative sputtered species outputs are related to their respective structures. Structural changes are shown to occur in MWCNTs and seen in SEM micrographs. The individual identity of the heavily bombarded MWCNTs may have given way to the merged structures while effects on the structure of heavily irradiated graphite grains size needs to be further investigated

description: A method for producing narrow-band THz radiation proposes passing an ultra-relativistic beam through a metallic pipe with small periodic corrugations. We present results of a measurement of such an arrangement at Brookhaven's Accelerator Test Facility (ATF). Our pipe was copper and was 5 cm long; the aperture was cylindrically symmetric, with a 1 mm (radius) bore and a corrugation depth (peak-to-peak) of 60 um. In the experiment we measured both the effect on the beam of the structure wakefield and the spectral properties of the radiation excited by the beam. We began by injecting a relatively long beam compared to the wavelength of the radiation, but with short rise time, to excite the structure, and then used a downstream spectrometer to infer the radiation wavelength. This was followed by injecting a shorter bunch, and then using an interferometer (also downstream of the corrugated pipe) to measure the spectrum of the induced THz radiation. For the THz pulse we obtain and compare with calculations: the central frequency, the bandwidth, and the spectral power---compared to a diffraction radiation background signal.

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: Robust knowledge of molecular gas mass is critical for understanding star formation in galaxies. The H$_{2}$ molecule does not emit efficiently in the cold interstellar medium, hence the molecular gas content of galaxies is typically inferred using indirect tracers. At low metallicity and in other extreme environments, these tracers can be subject to substantial biases. We present a new method of estimating total molecular gas mass in galaxies directly from pure mid-infrared rotational H$_{2}$ emission. By assuming a power-law distribution of H$_{2}$ rotational temperatures, we can accurately model H$_{2}$ excitation and reliably obtain warm ($T\!\gtrsim\!100$ K) H$_{2}$ gas masses by varying only the power law's slope. With sensitivities typical of Spitzer/IRS, we are able to directly probe the H$_{2}$ content via rotational emission down to ~80 K, accounting for ~15% of the total molecular gas mass in a galaxy. By extrapolating the fitted power law temperature distributions to a calibrated \emph{single} lower cutoff temperature, the model also recovers the total molecular content within a factor of ~2.2 in a diverse sample of galaxies, and a subset of broken power law models performs similarly well. In ULIRGs, the fraction of warm H$_{2}$ gas rises with dust temperature, with some dependency on $α_\mathrm{CO}$. In a sample of five low metallicity galaxies ranging down to 12+log[O/H]=7.8, the model yields molecular masses up to ~100 times larger than implied by CO, in good agreement with other methods based on dust mass and star formation depletion timescale. This technique offers real promise for assessing molecular content in the early universe where CO and dust-based methods may fail.

description: The on shell equivalence of first order and second order formalisms for the Einstein-Hilbert action does not hold for those actions quadratic in curvature. It would seem that by considering the connection and the metric as independent dynamical variables, there are no quartic propagators for any dynamical variable. This suggests that it is possible to get both renormalizability and unitarity along these lines. We have studied a particular instance of those theories, namely Weyl gravity. Although the ground state of this system is difficult to analyze, we have been able to study the physical effects of some external sources.

description: Acute pain caused by a dental etiology is a common reason why over-the-counter (OTC) pain medication is used. The study examined how children’s dental pain is being managed at home by parents/caregivers prior to their children seeking urgent care at the University of Illinois Chicago (UIC), College of Dentistry (COD), Post-Graduate Pediatric Dentistry Clinic. Legal guardians of patients (age 0-17) who presented to the clinic were asked to participate in this research. Consenting caregivers were asked to complete a survey with demographic information and pain management questions. A dental resident recorded pain scores using the Wong-Baker Faces pain scale1. In addition, the dental resident completed a clinical and/or radiographic examination to determine the etiology of the dental pain. Statistical analysis was completed using SPSS. Pain medication was given to 39% of patients. Twenty-nine of the 38 children who were given medication had errors or incomplete information in the reported dosing by the caregiver. Analysis showed only an association between caregiver’s race and whether the dosage of the medication was known (P = .044) as well as between caregiver’s race and if there were errors or incomplete information in the reported dosing (P = .044). There were no other associations between demographic information and pain medication knowledge. There was also no association between duration of pain and whether pain medication was given. However, there was a significant association between the Wong-Baker Faces pain scale recorded and medication use.viiiOverall, it is hard to predict which parents have adequate knowledge on how to manage their child’s dental pain. Our findings suggest a large percentage of our population experience pain and provide some form of pain management, receive information from various sources, and often have gaps in pain management knowledge. It is imperative that healthcare providers educate parents on appropriate and accurate pain management skills and that prevention efforts aim to prevent the need for pain management as tertiary care.

description: A retrospective cross-sectional study was conducted on patients scheduled for moderate sedation dental visits at the UIC COD between January 1, 2018 and November 1, 2019. Details regarding patients’ first scheduled moderate sedation appointments across this timespan were recorded. Information on patient demographics, appointment characteristics, and clinic experience were collected. Information regarding whether the sedation was completed or not was recorded; and if the sedation was incomplete, the reasoning for why it did not get completed was documented. The goal of this study was to assess which factors are associated with failed moderate sedation appointments.Over the course of twenty-two months, 618 patients were scheduled for moderate sedation appointments at UIC COD. In all, 1058 moderate sedation appointments were scheduled with each patient on average scheduling 1.72 sedation appointments. Of the first scheduled encounters, 512 patients (82.9 %) attended their appointment and 106 patients (17.1%) either canceled or failed the visit.In total, of the 512 attended moderate sedation visits, 410 first-time sedations (80.1%) were completed and 102 appointments (19.9%) did not have a sedation go through. Among the reasons for attended sedation non-completion, airway (n = 33, 35.3%), illness (n = 29, 28.4%), and NPO violation (n=22, 21.5%) were the most common. This leads us to believe that airway assessment calibration could be improved across residents and staff at UIC COD. Additionally, we found several factors associated with an increased rate of patient attendance to their dental sedation appointment.

description: The phenomenon of the displacement of the position of the pressure, intensity and acoustic radiation force maxima along the axis of focused acoustic beams under increasing driving amplitudes (nonlinear focal shift) is studied for the case of a moderately focused beam excited with continuous and 25 kHz amplitude modulated signals, both in water and tissue. We prove that in amplitude modulated beams the linear and nonlinear propagation effects coexist in a semi-period of modulation, giving place to a complex dynamic behaviour, where the singular points of the beam (peak pressure, rarefaction, intensity and acoustic radiation force) locate at different points on axis as a function of time. These entire phenomena are explained in terms of harmonic generation and absorption during the propagation in a lossy nonlinear medium both, for a continuous and an amplitude modulated beam. One of the possible applications of the acoustic radiation force displacement is the generation of shear waves at different locations by using a focused mono-element transducer excited with an amplitude modulated signal.

description: In this paper we outline the approach of solving special type of navigation tasks for robotic systems, when a coalition of robots (agents) acts in the 2D environment, which can be modified by the actions, and share the same goal location. The latter is originally unreachable for some members of the coalition, but the common task still can be accomplished as the agents can assist each other (e.g. by modifying the environment). We call such tasks smart relocation tasks (as the can not be solved by pure path planning methods) and study spatial and behavior interaction of robots while solving them. We use cognitive approach and introduce semiotic knowledge representation - sign world model which underlines behavioral planning methodology. Planning is viewed as a recursive search process in the hierarchical state-space induced by sings with path planning signs reside on the lowest level. Reaching this level triggers path planning which is accomplished by state of the art grid-based planners focused on producing smooth paths (e.g. LIAN) and thus indirectly guarantying feasibility of that paths against agent's dynamic constraints.

description: We study the Casimir vacuum energy density and the Casimir pressure for a massless scalar field confined between two nearby parallel plates in a slightly curved, static spacetime background, employing the weak field approximation in the framework of Extended Theories of Gravity (ETG). Following a perturbative approach upto second order, we find the gravity correction in the ETG to Casimir vacuum energy density and pressure. The corrections to the vacuum energy density in presence of curved spacetime in the framework of General Relativity (GR) are small and today they are still undetected with the current technology. However, future sensitivity improvement in gravitational interferometer experiments will give an useful tool to detect such effect induced by gravity. For these reason we retain interesting from a theoretical point of view generalize the outcomes of GR in the context of ETG. Finally, we find the general relation to constraining the free parameters of the ETG.

Creators: name: Hassan, Thomas
Year: 2023

description: Unter welchen Umständen, wie und warum entwickeln Gruppen ein eigenes Liedgut? Was kann eine solche Entwicklung befördern, welche Voraussetzungen sind dafür notwendig? Um diese Fragen zu bearbeiten, wurde eine überschaubare und langlebige Gruppe gewählt. Die Fantasygemeinschaft FOLLOW ist eine Gruppe, die seit den 1960er-Jahren besteht und seit den 1980er-Jahren eine eigene Musikkultur entwickelt hat. Die vorliegende Arbeit beruht auf umfangreichen Gesprächen und Beobachtungen sowie einer Umfrage, die im Zuge der Feldforschung 2022 durchgeführt wurde. Die Funktionen und Wirkungen der Musik in den sozialen Situationen während der Treffen der Gemeinschaft werden beschrieben und analysiert. Insbesondere wird auch genauer be- trachtet, wie die Liedproduktion durch Neutextierung funktioniert und welche Mechanismen dabei wirken.
title: An Exploratory Study of Research Utilization by Virginia Nurse Educators

description: The purposes of this study were: to explore research utilization by three groups of Virginia nursing educators; and to determine if differences in stages of diffusion existed between nurse educators working in hospital diploma, associate degree and baccalaureate degree settings within the Commonwealth of Virginia. A stratified random sample included 28 hospital diploma, 41 associate degree and 37 baccalaureate degree nurse educators from the Commonwealth of Virginia, who completed the Nurse Educator Questionnaire (NEQ). Two free-response questions were used to identify factors which the nurse educators perceived as inhibitors and facilitators to research utilization. The results of a two-step mailed survey revealed no significant differences between the three groups of nurse educators on the basis of stages of diffusion. Qualitative analysis failed to reveal that the groups differed during the stages of diffusion on the basis of selected demographic characteristics. Implications for nursing education and strategies for improving utilization of research findings were discussed and recommendations for instrument revision as well as future research were suggested.

description: The electric dipole moment of an electron (eEDM) is one of the sensitive probes of physics beyond the standard model. The possible existence of the eEDM gives rise to an experimentally observed energy shift, which is proportional to the effective electric field (Eeff) of a target molecule. Hence, an analysis of the quantities that enhance Eeff is necessary to identify suitable molecules for eEDM searches. In the context of such searches, it is generally believed that a molecule with larger electric polarization also has a larger value of Eeff. However, our Dirac-Fock and relativistic coupled-cluster singles and doubles calculations show that the hydrides of Yb and Hg have larger Eeff than those of fluorides, even though their polarizations are smaller. This is due to significant mixing of valence s and p orbitals of the heavy atom in the molecules. This mixing has been attributed to the energy differences of the valence atomic orbitals and the overlap of the two atomic orbitals based on the orbital interaction theory.

description: Heteroepitaxial growth of transition-metal oxide films on the open (111) surface of SrTiO3 results in significant restructuring due to the polar mismatch. Monitoring the structural and composition on an atomic scale of LaNiO3/SrTiO3 (111) interface as a function of processing conditions has enabled the avoidance of the expected polar catastrophe. Using atomically resolved transmission electron microscopy and spectroscopy as well as Low energy electron diffraction, the structure of the thin film, from interface to the surface, has been studied. In this paper, we show that the proper processing can lead to a structure that is ordered, coherent with the substrate without intermediate structural phase. Angle-resolved X-ray photoemission spectroscopy shows that the oxygen content of thin films increases with the film thickness, indicating that the polar mismatch is avoided by the presence of oxygen vacancies.

description: We study the interaction between heterogeneously charged surfaces in an electrolyte solution by employing classical Density Functional Theory (cDFT) and Monte Carlo simulations. We observe a consistent behavior between cDFT and Monte Carlo simulations regarding force curves and two-dimensional density profiles. Armed with the validated cDFT, we explore the system's behavior under parameters challenging to simulate directly .Our findings include impacts of domain size, domain charge, domain charge configuration, and bulk electrolyte concentration on the osmotic pressure. Remarkably, the force curve is more sensitive to the domain size for asymmetric configuration than symmetry configuration; the bulk concentration weakly influences the force curve independent of the system configurations.

description: We demonstrate that dynamics of the ab-spiral-spin order in a magnetoelectric multiferroic Eu0.55Y0.45MnO3 can be unambiguously probed through optical second harmonic signals, generated via the spin-induced ferroelectric polarization. In the case of relatively weak photoexcitation,the ferroelectric and the spiral-spin order remains interlocked, both relaxing through spin-lattice relaxation in the non-equilibrium state. When the additional optical pulse illuminating sample is intense enough to induced a local phase transition thermally, the system creates a metastable state of the bc-spiral-spin order (with the electric polarization P//c) via supercooling across the first-order phase transition between ab- and bc-spiral. The supercooled state of bc-spiral spin is formed in the thermodynamical ground state of ab-spiral (P//a), displaying a prolonged lifetime with strong dependence on the magnetic field along the a-axis. The observed photo-switching between the two distinct multiferroic states sheds light on novel photoinduced phenomena in spiral-spin multiferroics.
title: The Influence of Lamaze Classes and Delivery Room Presence on Paternal Attachment Behavior

description: The purpose of this research was to determine the significance of attendance of Lamaze classes and(or presence in the delivery room on paternal attachment behaviors. Seventeen white, first-time fathers, ages 20 to 35, were observed in the mother's hospital room within 72 hours of birth using a modified paternal attachment tool. The behaviors observed included verbalization, inspection, holding, en face, smiling, and tactile response. Observations were scored on 30-second intervals for a total of 15 minutes. Fathers were then placed into one of the following groups: Group I (n 10) — Fathers from Lamaze classes and present in the delivery room; Group II (n=3) - Fathers from no classes and present in the delivery room; Group III (n 3) — Fathers from no classes and not present in the delivery room; Group IV (n 1) — Fathers from Lamaze classes and not present in the delivery room. Analysis of variance indicated no significant difference in individual or overall scores of attachment behaviors among the groups of fathers.
