description: Let $Γ_1,\dots,Γ_n$ be hyperbolic, property (T) groups, for some $n\ge 1$. We prove that if a product $Γ_1\times\dots\timesΓ_n \curvearrowright X_1\times\dots\times X_n$ of measure preserving actions is stably orbit equivalent to a measure preserving action $Λ\curvearrowright Y$, then $Λ\curvearrowright Y$ is induced from an action $Λ_0\curvearrowright Y_0$ such that there exists a direct product decomposition $Λ_0=Λ_1\times\dots\timesΛ_n$ into $n$ infinite groups. Moreover, there exists a measure preserving action $Λ_i\curvearrowright Y_i$ that is stably orbit equivalent to $Γ_i\curvearrowright X_i$, for any $1\leq i\leq n$, and the product action $Λ_1\times\dots\timesΛ_n\curvearrowright Y_1\times\dots\times Y_n$ is isomorphic to $Λ_0\curvearrowright Y_0$.

description: Inspired by the Generalized Proca Theory, we study a vector-tensor model of inflation with massive vector fields and derivative self-interactions. The action under consideration contains a usual Maxwell-like kinetic term, a general potential term and a term with non-minimal derivative coupling between the vector field and gravity, via the dual Riemann tensor. In this theory, the last term contains a free parameter, $λ$, which quantifies the non-minimal derivative coupling. In this scenario, taking into account a spatially flat FRW universe and a general vector field, we obtain the general expressions for the equation of motion and the total energy momentum tensor. Choosing a Proca-type potential, a suitable inflationary regimen driven by massive vector fields is studied. In this model, the isotropy of expansion is guaranteed by considering a triplet of orthogonal vector fields. In order to obtain an inflationary solution with this model, the quasi de Sitter expansion was considered. In this case the vector field behaves as a constant. Finally, slow roll analysis is performed and slow-roll conditions are defined for this model, which, for suitable constraints of the model parameters, can give the required number of e-folds for sufficient inflation.

description: The effect of water deficit on drought-sensitive peat mosses’ photosynthetic activities were analyzed in Sphagnum denticulatum genotypes representing two ecotypes–aquatic and terrestrial. All plants, cultivated for a long time in common garden conditions, were desiccated to a water content of less than 2% of controls and subsequently rehydrated for up to 30 days. The aquatic control plants showed shade adaptations as expressed by the F0, Fv/F0 and Chl a/b ratios which may reflect the conditions at the parental habitat. The ecotype- and genotype-specific responses to desiccation and rehydration were observed. Under desiccation, the photoinhibition was greater in the terrestrial plants (as demonstrated by lower Fv/Fm and ΦPSII), in comparison with the aquatic plants. This suggests either severe damage of photo centers or better photoprotection mechanisms. Although there were no consistent differences between ecotypes across treatments, the signs of intraspecific variation in desiccation sensitiveness, which presumably arose from plasticity and local adaptation of plants to their parental environments, were detected. Genotypes and their place of origin should be taken into account in future studies.

description: The concept of negotiation is often used in contemporary sociocultural and constructivist perspectives and theories of adults’ learning in and for work. It is used to bring a range of meanings to the description and explanation of work learning as an interactive process of active participation in and with the resources that constitute work. At its most fundamental, that interaction is between the worker and their context, between the individual and their immediate situation. At its most complex, that interaction is multiply enacted and dynamically experienced as all the resources – the personal, social, cultural, historic, material, and ideational influences – that shape work and workers’ engagement. These resources are variously mediating how and in what ways workers’ interactions can be observed, interpreted, and understood as the constant flux of reality. Across all these momentary and lifelong interactions, whether as concrete as hammering a nail or as abstract as metaphysics, the concept of negotiation supports understanding workers’ activities as interdependent with and relational to all else that is happening for, by, and to them. This support comes from the broad range of meanings the concept carries, particularly those meanings that evoke notions of joint activity in search of solution and agreement as the means of moving forward from a base of difference. Such joint activity is evidence of needing each other and needing to interact to accomplish something. So, negotiation comes to be synonymous with interaction and co-participation and, thereby, generally descriptive and explanatory of learning in and for work as social activity.

description: During helium burning in the core of a red giant, the relative rates of the 3&alpha and ^{12}C(&alpha,&gamma)^{16}O reactions largely determine the final ratio of carbon to oxygen in the resulting white dwarf star. The uncertainty in the 3&alpha reaction at stellar energies due to the extrapolation from high-energy laboratory measurements is relatively small, but this is not the case for the ^{12}C(&alpha,&gamma)^{16}O reaction. Recent advances in the analysis of asteroseismological data on pulsating white dwarf stars now make it possible to obtain precise measurements of the central ratio of carbon to oxygen, providing a more direct way to measure the ^{12}C(&alpha,&gamma)^{16}O reaction rate at stellar energies. We assess the systematic uncertainties of this approach and quantify small shifts in the measured central oxygen abundance originating from the observations and from model settings that are kept fixed during the optimization. Using new calculations of white dwarf internal chemical profiles, we find a rate for the ^{12}C(&alpha,&gamma)^{16}O reaction that is significantly higher than most published values. The accuracy of this method may improve as we modify some of the details of our description of white dwarf interiors that were not accessible through previous model-fitting methods.

description: We have identified a new group of galaxies, CG J0247+44.9, at low Galactic latitude (l=143.64 deg, b=-13.29 deg), which satisfies Hickson's criteria (Hickson 1997) for Compact Groups (CGs). Our group consists of six members, two of which are in close interaction (IRAS 02443+4437). We present here optical photometry (BVRI) and low resolution spectroscopy of the individual galaxies and investigate the global properties of the group. Our morphological analysis reveals that two out of the six objects are lenticular galaxies. The others are spirals showing emission lines in their spectra through which we could classify them as a starburst galaxy (the spiral member of the IRAS 02443+4437 close pair), a Seyfert 2, a LINER and a weak H II galaxy. Since the S0/Sa is the prevailing morphology for the galaxies of this group, which is also characterized by a short crossing time and a relatively high velocity dispersion, we suggest that CG J0247+44.9 is a dynamically old compact group.

description: Excerpts from the report Summary: Aeration is a generally accepted practice for maintaining the condition of stored grain. Properly applied, aeration may be accomplished with upward or downward airflow, with a wide range of airflow rates, and with many different seasonal and daily operating schedules. However, each method of operating aeration systems has some advantages and some limitations which should be recognized. Various methods of operating aeration systems were observed under test conditions in the Corn Belt. Wheat in deep bins, shelled corn in both deep bins and flat storages, and soybeans in "oil-tank" type of storages were included in the tests. Observations were made of the changes in grain temperatures and moisture, mold development and insect activity, and volume and distribution of air.

Исследуемые группы включают больных с пролежнями, нейротрофическими язвами и трофическими язвами после тромбофлебита. В контрольной группе средняя площадь ран составила 88,2 ± 29,7 мм², глубина — 3,5 ± 0,34 единиц, в основной группе — 92,6 ± 32,7 мм² и 3,7 ± 0,4 единиц, соответственно. Наибольшее различие по площади и глубине наблюдается при пролежнях, а наименьшее — при нейротрофических язвах. Полученные данные подтверждают значительное влияние формы раны на размеры и глубину поражения, что влияет на исходы лечения и прогнозирование заживления.

description:
Robotic assistive or rehabilitative devices are promising aids for people with neurological disorders as they help regain normative functions for both upper and lower limbs. However, it remains challenging to accurately estimate human intent or residual efforts non-invasively when using these robotic devices. In this article, we propose a deep learning approach that uses a brightness mode, that is, B-mode, of ultrasound (US) imaging from skeletal muscles to predict the ankle joint net plantarflexion moment while walking. The designed structure of customized deep convolutional neural networks (CNNs) guarantees the convergence and robustness of the deep learning approach. We investigated the influence of the US imaging's region of interest (ROI) on the net plantarflexion moment prediction performance. We also compared the CNN-based moment prediction performance utilizing B-mode US and sEMG spectrum imaging with the same ROI size. Experimental results from eight young participants walking on a treadmill at multiple speeds verified an improved accuracy by using the proposed US imaging + deep learning approach for net joint moment prediction. With the same CNN structure, compared to the prediction performance by using sEMG spectrum imaging, US imaging significantly reduced the normalized prediction root mean square error by 37.55% ( < .001) and increased the prediction coefficient of determination by 20.13% ( < .001). The findings show that the US imaging + deep learning approach personalizes the assessment of human joint voluntary effort, which can be incorporated with assistive or rehabilitative devices to improve clinical performance based on the assist-as-needed control strategy.

description: Soft particles at fluid interfaces play an important role in many aspects of our daily life, such as the food industry, paints and coatings, and medical applications. Analytical methods are not capable of describing the emergent effects of the complex dynamics of suspensions of many soft particles, whereas experiments typically either only capture bulk properties or require invasive methods. Computational methods are therefore a great tool to complement experimental work. However, an efficient and versatile numerical method is needed to model dense suspensions of many soft particles. In this article we propose a method to simulate soft particles in a multi-component fluid, both at and near fluid-fluid interfaces, based on the lattice Boltzmann method, and characterize the error stemming from the fluid-structure coupling for the particle equilibrium shape when adsorbed onto a fluid-fluid interface. Furthermore, we characterize the influence of the preferential contact angle of the particle surface and the particle softness on the vertical displacement of the center of mass relative to the fluid interface. Finally, we demonstrate the capability of our model by simulating a soft capsule adsorbing onto a fluid-fluid interface with a shear flow parallel to the interface, and the covering of a droplet suspended in another fluid by soft particles with different wettability.

description: The role of superintendent is complex and evolving. The pool of viable superintendent candidates may be facing an impending shortage over the next several years. This paper examines the most viable motivators and inhibitors that superintendents report for persisting in the role and conversely, for considering exiting the field. Motivators consist of altruistic reasons for serving including the desire to make a difference, building a leadership team, the ability to affect communities, be an agent of change, and to transform school organizations. The inhibitors highlight superintendents’ concerns with school finance models, increased stressors and time commitment for the job, the politics of conflict with their school boards, and a lack of minority representation. The literature provides recommendations for mitigating inhibitors, including increased training and communication to support healthy superintendent-board relations, diversifying the pool of candidates, and raising awareness in leadership preparation programs for the management of job stressors. These measures are critical to the vitality of the superintendency, especially in light of a shrinking pool of viable, diversified candidates. A study was conducted to identify the inhibitors, motivators, and strategies for three Latina superintendents serving in the superintendent role in Texas. The study design was a qualitative multiple-case study of the phenomenon of the Latina superintendents within their contextual environments. Data for the study were analyzed using grounded theory methodology. The study findings reveal recommendations for leveraging motivators, alleviating inhibitors, and removing access barriers for Latina aspirants to the role

description: The dissipative properties of an optical cavity can be effectively controlled by placing it in a feedback loop where the light at the cavity output is detected and the corresponding signal is used to modulate the amplitude of a laser field which drives the cavity itself. Here we show that this effect can be exploited to improve the performance of an optomechanical heat engine which makes use of polariton excitations as working fluid. In particular we demonstrate that, by employing a positive feedback close to the instability threshold, it is possible to operate this engine also under parameters regimes which are not usable without feedback, and which may significantly ease the practical implementation of this device.

description: Previous studies have investigated principal perceptions of cultural competence of already employed principals, principal standards, hiring decisions of school districts and principals. However, there is a gap in identifying what school districts are advertising and recruiting for culturally competent principals. The purpose of this study is to examine how school districts advertise, recruit and hire school principals for cultural proficiency through the lens of cultural competency conceptual framework (Terrell & Lindsey, 2009). Research questions: 1. In a school district emphasizing cultural competence, what hiring practices are used for culturally competent school leaders? a. What are the hiring procedures included in advertising, recruitment, screening, interview, and selection of principals of the school district? b. What culturally competent knowledge, skills, and dispositions do school district representatives use when hiring principals? This study uses a qualitative single case study approach on one public school district, Texas ISD. The school district identified in the study was selected due to the size and location of the school district within a large city. The school district also makes mention of cultural proficiency in their utilization of the cultural competency conceptual framework (Tderrell & Lindsey, 2009). This study utilizes a qualitative research approach of interviews and document analysis as data collection. Content and textual analysis (Davis, Gooden, & Micheaux, 2015) was used to examine job descriptions and additional documents. Findings indicated Texas ISD was strategic and purposeful in their hiring practices from the recruitment to the selection of school principals. Cultural competencies were reflective in several different portions of the hiring practices however, was not reflective in all aspects of the hiring practices of the school district. The study provides knowledge to the body of research of culturally competent leaders. Assessing the hiring practices of school districts for school principals assist in understanding how school districts identify the leadership capacity of principals in their cultural proficiency. The focus is on school principals because of their vital impact on campuses including in both teacher and student success. A call to action for school districts to examine their hiring practices and how they are hiring the best candidates for culturally diverse schools. This research study supports the following areas of research: culturally competent leadership, leadership, human resource hiring practices, and K–12 public school districts

description: We investigate whether the recently-observed population of high-velocity white dwarfs can be derived from a population of binaries residing initially within the thin disk of the Galaxy. In particular we consider binaries where the primary is sufficiently massive to explode as a type II supernova. A large fraction of such binaries are broken up when the primary then explodes as a supernova owing to the combined effects of the mass loss from the primary and the kick received by the neutron star on its formation. For binaries where the primary evolves to fill its Roche lobe, mass transfer from the primary leads to the onset of a common envelope phase during which the secondary and the core of the primary spiral together as the envelope is ejected. Such binaries are the progenitors of X-ray binaries if they are not broken up when the primary explodes. For those systems which are broken up, a large number of the secondaries receive kick velocities ~100 - 200 km/s and subsequently evolve into white dwarfs. We compute trajectories within the Galactic potential for this population of stars and relate the birthrate of these stars over the entire Galaxy to those seen locally with high velocities relative to the LSR. We show that for a reasonable set of assumptions concerning the Galactic supernova rate and the binary population, our model produces a local number density of high-velocity white dwarfs compatible with that inferred from observations. We therefore propose that a population of white dwarfs originating in the thin disk may make a significant contribution to the observed population of high-velocity white dwarfs.

description: Steiner's circumellipse is the unique geometric regularization of any triangle to a circumscribed ellipse with the same centroid, a regularization that motivates our introduction of the Steiner triangle as a minimal model for liquid droplet dynamics. The Steiner drop is a deforming triangle with one side making sliding contact against a planar basal support. The center of mass of the triangle is governed by Newton's law. The resulting dynamical system lives in a four dimensional phase space and exhibits a rich one-parameter family of dynamics. Two invariant manifolds are identified with "bouncing" and "rocking" periodic motions; these intersect at the stable equilibrium and are surrounded by nested quasiperiodic motions. We study the inherently interesting dynamics and also find that this model, however minimal, can capture space-time symmetries of more realistic continuum drop models.

description: A new telescope design based on Baker-Nunn optics is proposed for observation of ultra high-energy cosmic rays (UHECRs). The optical system has an image resolution of smaller than 0.02$^\circ$ within a wide field of view of 50$^\circ$ angular diameter. When combined with a high-quality imaging device, the proposed design enables the directions of UHECRs and high-energy neutrinos to be determined with accuracy of better than 1 arcmin. The outstanding resolution of this telescope allows charge-separated cosmic-rays to be resolved and the source to be determined accurately. This marked improvement in angular resolution will allow the multi-wavelength and ``multi-particle'' observations of astronomical objects through collaboration with established astronomical observations.

description: The rectangular collocation approach makes it possible to solve the Schrödinger equation with basis functions that do not have amplitude in all regions in which wavefunctions have significant amplitude. Collocation points can be restricted to a small region of space. As no integrals are computed, there are no problems due to discontinuities in the potential, and there is no need to use integrable basis functions. In this paper, we show, for the Kohn-Sham equation, that machine learning can be used to drastically reduce the size of the collocation point set. This is demonstrated by solving the Kohn-Sham equations for CO and H2O. We solve the Kohn-Sham equation on a given effective potential which is a critical part of all DFT calculations, and monitor orbital energies and orbital shapes. We use a combination of Gaussian process regression and a genetic algorithm to reduce the collocation point set size by more than an order of magnitude (from about 51,000 points to 2,000 points) while retaining mHartree accuracy.

description: Machine-learning techniques have proved successful in identifying ordered phases of matter. However, it remains an open question how far they can contribute to the understanding of phases without broken symmetry, such as spin liquids. Here we demonstrate how a machine learning approach can automatically learn the intricate phase diagram of a classical frustrated spin model. The method we employ is a support vector machine equipped with a tensorial kernel and a spectral graph analysis which admits its applicability in an effectively unsupervised context. Thanks to the interpretability of the machine we are able to infer, in closed form, both order parameter tensors of phases with broken symmetry, and the local constraints which signal an emergent gauge structure, and so characterize classical spin liquids. The method is applied to the classical XXZ model on the pyrochlore lattice where it distinguishes---among others---between a hidden biaxial spin nematic phase and several different classical spin liquids. The results are in full agreement with a previous analysis by Taillefumier \emph{et al.} [Phys. Rev. X 7, 041057 (2017)], but go further by providing a systematic hierarchy between disordered regimes, and establishing the physical relevance of the susceptibilities associated with the local constraints. Our work paves the way for the search of new orders and spin liquids in generic frustrated magnets.

description: We applied restriction site-associated DNA sequencing (RAD-Seq) to yellow perch geographic demes to develop large numbers of polymorphic genetic markers, including single nucleotide polymorphisms and simple sequence repeats, and to evaluate nucleotide diversity. A total of 258,056 contigs were assembled with the length of 605 ± 71 (mean ± SD) bp, which were longer than those just using HiSeq data. Nucleotide diversity (π) was 0.00304 with 95% confidence intervals from 0.00303 to 0.00304. Based on the assembled sequences, a total of 59,766 perfect single sequence repeats were detected, with AC/GT being the most common repeat motif and GC being the rarest. Based on this breeding population, 41,736 high-quality single nucleotide polymorphisms and 10,412 polymorphic single sequence repeats were obtained. Validation of amplification by randomly selecting 40 polymorphic single sequence repeats showed a high success rate (85%).

description: Excerpt from the report Summary: In ranking a pre-selected list of fabric characteristics in women's dresses, three characteristics stood out as important to women as consumers regardless of occasion or season: (1) Ability of the fabric to hold shape; (2) degree to which the fabric will or will not wrinkle; and (3) color fastness. Cost was also an important consideration even though homemakers may be willing to pay quite different amounts for a dress. The income level of consumers may vary, but even those at the upper end of the economic scale do not ignore costs. In most respects, then, manufacturers of women's dresses appeared to be doing an excellent job in meeting the needs of consumers. Improvements such as wrinkle resistance, no-iron, and nonsag made in the past few years are rapidly being accepted as essentials in a fabric. However, in some areas, the characteristics have not yet met the hopes of all consumers. There is still room for product improvement.

description: The behavior of users of music streaming services is investigated from the point of view of the temporal dimension of individual songs; specifically, the main object of the analysis is the point in time within a song at which users stop listening and start streaming another song ("skip"). The main contribution of this study is the ascertainment of a correlation between the distribution in time of skipping events and the musical structure of songs. It is also shown that such distribution is not only specific to the individual songs, but also independent of the cohort of users and, under stationary conditions, date of observation. Finally, user behavioral data is used to train a predictor of the musical structure of a song solely from its acoustic content; it is shown that the use of such data, available in large quantities to music streaming services, yields significant improvements in accuracy over the customary fashion of training this class of algorithms, in which only smaller amounts of hand-labeled data are available.

description: Rotation measure synthesis allows the estimation of Faraday dispersion via a Fourier transform and is the primary tool to probe cosmic magnetic fields. We show this can be considered mathematically equivalent to the one dimensional interferometric intensity measurement equation, albeit in a different Fourier space. As a result, familiar concepts in two dimensional intensity interferometry designed to correctly account for a range of instrumental conditions can be translated to the analysis of Faraday dispersion. In particular, we show how to model the effect of channel averaging during Faraday reconstruction, which has to date limited the progress of polarimetic science using wide-band measurements. Further, we simulate 1d sparse reconstruction with channel averaging for realistic frequency coverages, and show that it is possible to recover signals with large rotation measure values that were previously excluded from possible detection. This is especially important for low-frequency and wide-band polarimetry. We extended these ideas to introduce mosaicking in Faraday depth into the channel averaging process. This work, thus provides the first framework for correctly undertaking wide-band rotation measure synthesis, including the provision to add data from multiple telescopes, a prospect that should vastly improve the quality and quantity of polarimetric science. This is of particular importance for extreme environments which generate high magnetic fields such as those associated with pulsars and Fast Radio Bursts (FRBs), and will allow such sources to be accurately used as probes of cosmological fields.

description: The mining of Virtual Observatories (VOs) is becoming a powerful new method for discovery in astronomy. Here we report on the development of SkyDOT (Sky Database for Objects in the Time domain), a new Virtual Observatory, which is dedicated to the study of sky variability. The site will confederate a number of massive variability surveys and enable exploration of the time domain in astronomy. We discuss the architecture of the database and the functionality of the user interface. An important aspect of SkyDOT is that it is continuously updated in near real time so that users can access new observations in a timely manner. The site will also utilize high level machine learning tools that will allow sophisticated mining of the archive. Another key feature is the real time data stream provided by RAPTOR (RAPid Telescopes for Optical Response), a new sky monitoring experiment under construction at Los Alamos National Laboratory (LANL).

description: We report ultra-low intrinsic magnetic damping in Co$_{\text{25}}$Fe$_{\text{75}}$ heterostructures, reaching the low $10^{-4}$ regime at room temperature. By using a broadband ferromagnetic resonance technique, we extracted the dynamic magnetic properties of several Co$_{\text{25}}$Fe$_{\text{75}}$-based heterostructures with varying ferromagnetic layer thickness. By estimating the eddy current contribution to damping, measuring radiative damping and spin pumping effects, we found the intrinsic damping of a 26\,nm thick sample to be $$α_{\mathrm{0}} \lesssim 3.18\times10^{-4}$. Furthermore, using Brillouin light scattering microscopy we measured spin-wave propagation lengths of up to $(21\pm1)\,\mathrm{μm}$ in a 26 nm thick Co$_{\text{25}}$Fe$_{\text{75}}$ heterostructure at room temperature, which is in excellent agreement with the measured damping.

Evidence for Circumstellar Disks around Young Brown Dwarfs in the Trapezium Cluster

description: We report the results of deep infrared observations of brown dwarf candidates in the Trapezium cluster in Orion. Analysis of the JHK color-color diagram indicates that a large fraction (approx 65% +/- 15%) of the observed sources exhibit infrared excess emission. This suggests the extreme youth of these objects and in turn, provides strong independent confirmation of the existence of a large population of substellar objects in the cluster. Moreover, this suggests that the majority of these substellar objects are presently surrounded by circumstellar disks similar to the situation for the stellar population of the cluster. This evidence for a high initial disk frequency (> 50%) around cluster members of all masses combined with the smooth continuity of the cluster's initial mass function across the hydrogen burning limit suggests that a single physical mechanism is likely responsible for producing the entire cluster mass spectrum down to near the deuterium burning limit. The results may also indicate that even substellar objects are capable of forming with systems of planetary companions.
