description: We investigate the transverse polarization of a hyperon produced in the high-energy unpolarized proton-proton collision, $pp\toΛ^\uparrow X$, based on the collinear twist-3 factorization formalism. We focus on the contribution from the twist-3 distribution in one of the unpolarized proton and the transversity fragmentation function for the final hyperon. Utilizing the "master formula" for the soft-gluon-pole cross section, we clarify the reason for why it receives only the derivative term of the twist-3 distribution. We also present the first computation of the soft-fermion-pole cross section and found that it vanishes. This means that the derivative of the soft-gluon-pole function is the only source for the twist-3 cross section from the unpolarized twist-3 distribution, which provides a useful basis for a phenomenological analysis.

description: Sleep disturbances are included in supportive Rett syndrome diagnostic criteria as they are highly prevalent in patients with Rett syndrome, however, the link between Rett syndrome and sleep has not been well established (Shelton & Malow 2021). A large study that included 320 families with a child with Rett syndrome reported that 80% of patients experience sleep disturbances. The most common was night screaming and laughing, reported in 49% and 77% of patients, respectively (Wong et al 2015). Other disturbances include insomnia, arousal and movement disorders, gastrointestinal dysfunction, seizures, and sleep disordered breathing (Tarquinio et al 2018). Patients with Rett syndrome have been found to have decreased sleep efficacy and more frequent nighttime awakenings, altered REM and deep sleep, and abnormal gross and twitch movements due to hyper-arousability and hyper-motor restlessness (Ramirez et al 2020). The use of medication as a primary treatment was associated with only 1.7% reduction in reported sleep disturbances in patients with Rett syndrome (Wong et al 2015). The objectives of this scoping review are 1) to investigate the literature on sleep disturbances experienced by patients with Rett syndrome in order to better inform our understanding of how Rett syndrome affects sleep architecture, 2) identify the tools used to assess sleep as a primary or secondary outcome, and 3) determine the effects on sleep of interventions used to treat symptoms of Rett syndrome or sleep disturbances.

e-Learning for Radiographic Interpretation: Development of a Testing Module
Creators: name: Broome, Angela M.
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: The purpose of this study was to develop a web-based method for testing dental students on the radiographic interpretation of approximal tooth surfaces. Part I involved the development and validation of an image editing method for transplanting approximal surfaces from one radiograph to another. Using this technique, histologically verified surfaces were transplanted into existing clinical radiographs and images were altered to change caries risk perception. In part II, the prototype of the testing module was administered to 80 third year dental students for competency assessment. This study validated the use of image editing and showed overall satisfactory class performance for radiographic caries interpretation. Substantial variations in sensitivity and specificity were noted, indicating the need for individualized teaching strategies for a subgroup of students. An increase in perceived caries risk increased the sensitivity and decreased the specificity of radiographic caries detection.

description: In the framework of open quantum systems, we study the dynamics of a static polarizable two-level atom interacting with a bath of fluctuating vacuum electromagnetic field and explore under which conditions the coherence of the open quantum system is unaffected by the environment totally. For both a single-qubit and two-qubit systems, we find that the quantum coherence can not be protected from noise when the atom interacts with a non-boundary electromagnetic field. However, with the presence of a boundary, the dynamical conditions for the insusceptible of quantum coherence are fulfilled only when the atom is close to the boundary and is transversely polarizable. Otherwise, the quantum coherence can only be protected in some degree in other polarizable direction.

description: We present the serendipitous discovery of eclipse-like events around the massive white dwarf SDSS J152934.98+292801.9 (hereafter J1529+2928). We selected J1529+2928 for time-series photometry based on its spectroscopic temperature and surface gravity, which place it near the ZZ Ceti instability strip. Instead of pulsations, we detect photometric dips from this white dwarf every 38 minutes. Follow-up optical spectroscopy observations with Gemini reveal no significant radial velocity variations, ruling out stellar and brown dwarf companions. A disintegrating planet around this white dwarf cannot explain the observed light curves in different filters. Given the short period, the source of the photometric dips must be a dark spot that comes into view every 38 min due to the rotation of the white dwarf. Our optical spectroscopy does not show any evidence of Zeeman splitting of the Balmer lines, limiting the magnetic field strength to B<70 kG. Since up to 15% of white dwarfs display kG magnetic fields, such eclipse-like events should be common around white dwarfs. We discuss the potential implications of this discovery on transient surveys targeting white dwarfs, like the K2 mission and the Large Synoptic Survey Telescope.

Multiscale stabilization for convection-dominated diffusion in heterogeneous media

Publisher: name: arXiv
Year: 2015

description: We develop a Petrov-Galerkin stabilization method for multiscale convection-diffusion transport systems. Existing stabilization techniques add a limited number of degrees of freedom in the form of bubble functions or a modified diffusion, which may not sufficient to stabilize multiscale systems. We seek a local reduced-order model for this kind of multiscale transport problems and thus, develop a systematic approach for finding reduced-order approximations of the solution. We start from a Petrov-Galerkin framework using optimal weighting functions. We introduce an auxiliary variable to a mixed formulation of the problem. The auxiliary variable stands for the optimal weighting function. The problem reduces to finding a test space (a reduced dimensional space for this auxiliary variable), which guarantees that the error in the primal variable (representing the solution) is close to the projection error of the full solution on the reduced dimensional space that approximates the solution. To find the test space, we reformulate some recent mixed Generalized Multiscale Finite Element Methods. We introduce snapshots and local spectral problems that appropriately define local weight and trial spaces. In particular, we use energy minimizing snapshots and local spectral decompositions in the natural norm associated with the auxiliary variable. The resulting spectral decomposition adaptively identifies and builds the optimal multiscale space to stabilize the system. We discuss the stability and its relation to the approximation property of the test space. We design online basis functions, which accelerate convergence in the test space, and consequently, improve stability. We present several numerical examples and show that one needs a few test functions to achieve an error similar to the projection error in the primal variable irrespective of the Peclet number.

Tilting Saturn without tilting Jupiter: Constraints on giant planet migration
Creators: name: Brasser, R.

Publisher: name: arXiv
Year: 2015
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: The migration and encounter histories of the giant planets in our Solar System can be constrained by the obliquities of Jupiter and Saturn. We have performed secular simulations with imposed migration and N-body simulations with planetesimals to study the expected obliquity distribution of migrating planets with initial conditions resembling those of the smooth migration model, the resonant Nice model and two models with five giant planets initially in resonance (one compact and one loose configuration). For smooth migration, the secular spin-orbit resonance mechanism can tilt Saturn's spin axis to the current obliquity if the product of the migration time scale and the orbital inclinations is sufficiently large (exceeding 30 Myr deg). For the resonant Nice model with imposed migration, it is difficult to reproduce today's obliquity values, because the compactness of the initial system raises the frequency that tilts Saturn above the spin precession frequency of Jupiter, causing a Jupiter spin-orbit resonance crossing. Migration time scales sufficiently long to tilt Saturn generally suffice to tilt Jupiter more than is observed. The full N-body simulations tell a somewhat different story, with Jupiter generally being tilted as often as Saturn, but on average having a higher obliquity. The main obstacle is the final orbital spacing of the giant planets, coupled with the tail of Neptune's migration. The resonant Nice case is barely able to simultaneously reproduce the {orbital and spin} properties of the giant planets, with a probability ~0.15%. The loose five planet model is unable to match all our constraints (probability <0.08%). The compact five planet model has the highest chance of matching the orbital and obliquity constraints simultaneously (probability ~0.3%).

description: La présente étude s’intéresse aux parcours individuels et collectif des membres de l’association CasaPound Italia, un groupe de l’ultra-droite italienne ayant émergé au début des années 2000. Le parcours collectif des membres du groupe, au lieu d’être la fonction de facteurs structurels, est démonté comme étant redevable à l’évolution de séquences d’interactions : d’abord, la diffusion de tactiques, d’identités collectives et de réseaux dès les années 1980; la structuration de différents axes du groupe se basant sur les expériences antérieures des membres impliqués dès ses débuts et aux contextes d’engagement marqués par des bouleversements dans le milieu de l’ultra-droite des années 1990; enfin, l’implantation différenciée du groupe jusqu’à aujourd’hui dans les différentes régions de l’Italie, selon des dynamiques complexes locales, et ce, autant avec des acteurs externes à l’organisation qu’avec des membres de ses sections. En partant de l’analyse des événements vécus par les membres interviewés selon un temps long d’observation, on aperçoit ainsi le danger d’attribuer le parcours collectif à des facteurs hors du contrôle des militants et comme relevant du « registre de l’extraordinaire ». En ce qui a trait à leurs parcours individuels, au lieu de témoigner de trajectoires et de profils types en fonction de leur origine sociale, les entretiens révèlent la superposition d’éléments « typiques » de différents parcours. Les parcours sont ici replacés à l’intersection des cheminements individuels, des efforts déployés par l’organisation et des contextes d’engagement. Enfin, en dépit de points communs dans l’explication du maintien des engagements et des expériences du militantisme, les entretiens soulignent les variations des expériences vécues par chacun des militants en lien aux situations vécues.

description: We study the partition function of two versions of the continuum directed polymer in 1+1 dimension. In the full-space version, the polymer starts at the origin and is free to move transversally in the reals, and in the half-space version, the polymer starts at the origin but is reflected at the origin and stays in the negative reals. The partition functions solves the stochastic heat equation in full-space or half-space with mixed boundary condition at the origin; or equivalently the free energy satisfies the Kardar-Parisi-Zhang equation. We derive exact formulas for the Laplace transforms of the partition functions. In the full-space this is expressed as a Fredholm determinant while in the half-space this is expressed as a Fredholm Pfaffian. Taking long-time asymptotics we show that the limiting free energy fluctuations scale with exponent 1/3 and are given by the GUE and GSE Tracy-Widom distributions. These formulas come from summing divergent moment generating functions, hence are not mathematically justified. The primary purpose of this work is to present a mathematical perspective on the polymer replica method which is used to derive these results. In contrast to other replica method work, we do not appeal directly to the Bethe ansatz for the Lieb-Liniger model but rather utilize nested contour integral formulas for moments as well as their residue expansions.

Modeling Future Climate Change Impacts on North American Bumblebee Distributions

description: Climate change is an important contributor to the modification of many bumblebee species’ range boundaries. It was linked to widespread decline at the southern edge of their distribution and to their inability to colonize new areas at the northern edge. Additionally, bumblebee decline is aggravated by other anthropogenic threats like land use change, agricultural practices and pathogen spillover. Predicted consequences are numerous, and could lead to severe economic and ecological impacts on human populations. A species-specific assessment of potential climate change impacts on North American bumblebees, based on the most recent global change scenarios as used in the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), was done for the first time. Using a massive dataset of georeferenced bumblebee observations and general circulation models, a series of species distribution models explore the impact of different climate change scenarios on climatically suitable areas of 30 bumblebee species. Northward range shifts occur in most bumblebee species’ projected climatic niches, revealing potential hotspots – places projected to be climatically suitable to multiple species – under future climate scenarios. Areas where species are likely to be lost in the absence of intervention are substantial, particularly in eastern parts of the continent. Models showed significant contractions of current ranges even under the very optimistic scenario in which all species disperse at 10 km/year. Results indicate that managed relocation as well as habitat management should be considered as a conservation strategy for some species. This research serves as a foundation for broader discussion and research in a nascent research area. It may assist in establishing localities where first conservation efforts could be directed for vulnerable bumblebee species.
Valley currents and non-local resistances of graphene nanostructures with broken inversion symmetry from the perspective of scattering theory

description: Valley currents and non-local resistances of graphene nanostructures with broken inversion symmetry are considered theoretically in the linear response regime. Scattering state wave functions of electrons entering the nanostructure from the contacts represented by groups of ideal leads are calculated by solving the Lippmann- Schwinger equation and are projected onto the valley state subspaces to obtain the valley velocity fields and total valley currents in the nanostructures. In the tunneling regime when the Fermi energy is in the spectral gap around the Dirac point energy, inversion symmetry breaking is found to result in strong enhancement of the nonlocal 4 terminal Buttiker-Landauer resistance and in valley currents several times stronger than the conventional electric current. These strong valley currents are the direct result of the injection of electrons from a contact into the graphene in the tunneling regime. They are chiral and occur near contacts from which electrons are injected into the nanostructure whether or not a net electric current flows through the contact. It is also pointed out that enhanced non-local resistances in the linear response regime are not a signature of valley currents arising from the combined effect of the electric field and Berry curvature on the velocities of electrons.

description: Estimates from above and below by the same positive prototype function for suitably modified Green functions in bounded smooth domains under Dirichlet boundary conditions for elliptic operators L of higher order 2m ≥ 4 have been shown so far only when the principal part of L is the polyharmonic operator (−Δ)m. In the present note, it is shown that such kind of result still holds when the Laplacian is replaced by any second order uniformly elliptic operator in divergence form with smooth variable coefficients. For general higher order elliptic operators, whose principal part cannot be written as a power of second order operators, it was recently proved that such kind of result becomes false in general.

Such a fundamental material property is intimately related to not only the polarizability of individual atoms, but also the specific atomic arrangement in the crystal lattice. In this letter, we present both experimental and theoretical investigations on the dielectric constant of few-layer In2Se3 nano-flakes grown on mica substrates by van der Waals epitaxy. A nondestructive microwave impedance microscope is employed to simultaneously quantify the number of layers and local electrical properties. The measured dielectric constant increases monotonically as a function of the thickness and saturates to the bulk value at around 6 ~ 8 quintuple layers. The same trend of layer-dependent dielectric constant is also revealed by first-principle calculations. Our results of the dielectric response, being ubiquitously applicable to layered 2D semiconductors, are expected to be significant for this vibrant research field.

Biodegradation of N-Heterocyclic Aromatic Hydrocarbons in Contaminated Soil
Creators: name: Wang, Zhe

description: While progress has been made understanding the biodegradation of polycyclic aromatic hydrocarbons (PAHs) in contaminated soil, the fate of co-existing contaminants, such as nitrogen-containing heterocyclic aromatic hydrocarbons (azaarenes) is rarely reported. Compared to their PAH analogues, azaarenes have higher toxicity and mobility in the environment, which might pose significant risk to public health. In this research, the fate of three azaarenes (carbazole, acridine, and phenanthridine) in contaminated soil was investigated. Carbazole was degraded in both untreated soil and soil treated in a lab-scale aerobic bioreactor. For phenanthridine, co-metabolism with phenanthrene was a major mechanism for its removal from untreated soil. Both acridine and phenanthridine were not significantly removed in untreated soil when these compounds were examined individually, but were removed in the bioreactor. Overall, this study of the fate and biodegradation of three azaarenes in contaminated soil provided insights and potential for future research on bioremediation of azaarenes-contaminated sites.

description: Feature models are a helpful means to document, manage, maintain, and configure the variability of a software system, and thus are a core artifact in software product-line engineering. Due to the various purposes of feature models, they can be a cross-cutting concern in an organization, integrating technical and business aspects. For this reason, various stakeholders (e.g., developers and consultants) may get involved into modeling the features of a software product line. Currently, collaboration in such a scenario can only be done with face-to-face meetings or by combining single-user feature-model editors with additional communication and version-control systems. While face-to-face meetings are often costly and impractical, using version-control systems can cause merge conflicts and inconsistency within a model, due to the different intentions of the involved stakeholders. Advanced tools that solve these problems by enabling collaborative, real-time feature modeling, analogous to Google Docs or Overleaf for text editing, are missing. In this article, we build on a previous paper and describe (1) the extended formal foundations of collaborative, real-time feature modeling, (2) our conflict resolution algorithm in more detail, (3) proofs that our formalization converges and preserves causality as well as user intentions, (4) the implementation of our prototype, and (5) the results of an empirical evaluation to assess the prototype’s usability. Our contributions provide the basis for advancing existing featuremodeling tools and practices to support collaborative feature modeling. The results of our evaluation show that our prototype is considered helpful and valuable by 17 users, also indicating potential for extending our tool and opportunities for new research directions.

description: Aplastic anaemia is one of the common blood disorders.Acute aplastic anaemia has a high mortality rate and chronic aplastic anaemia(CAA) is difficult to treat, seriously affecting people's normal working life.The search for a safer and more effective treatment is therefore important in the management of CAA. In recent years, Chinese medicine has made many achievements in the treatment of CAA, among which several clinical studies have shown that Shenhong Buxue Decoction(SBD) can significantly improve symptoms and enhance the therapeutic effect. Therefore, we intend to conduct a systematic review to further elucidate the effectiveness and safety of SBD in CAA.We will search each database from the built-in until February 2022.The English literature mainly searches Cochrane Library, PubMed, EMBASE, and Web of Science, while the Chinese literature comes from CNKI, CBM, VIP, and Wangfang database. Simultaneously we will retrieval clinical registration tests and grey literatures. This study only screens the clinical randomized controlled trials (RCTs) about SBD for CAA to assess its efficacy and safety. The 2 researchers worked independently on literature selection, data extraction, and quality assessment. The dichotomous data is represented by relative risk (RR), and the continuous is expressed by mean difference (MD) or standard mean difference (SMD), eventually the data is synthesized using a fixed effect model (FEM) or a random effect model (REM) depending on whether or not heterogeneity exists. The clinical efficacy, peripheral haemoglobin, platelets and leucocytes were assessed as primary outcomes. Serum basic fibroblast growth factor(bFGF), Chorionic gonadotropin A(Rho-A), tumour necrosis factor-α(TNF-α) and interferon-γ(IFN-γ) were secondary outcomes. Finally, meta-analysis was conducted by RevMan software version 5.3.This study will provide high-quality evidence for treatment of CAA with SBD in terms of effectiveness and safety.This systematic review aims to provide new options for SBD treatment of CAA in terms of its efﬁcacy and safety.

description: Understanding emerging areas of a multidisciplinary research field is crucial for researchers,policymakers and other stakeholders. For them a knowledge structure based on longitudinal bibliographic data can be an effective instrument. But with the vast amount of available online information it is often hard to understand the knowledge structure for data. In this paper, we present a novel approach for retrieving online bibliographic data and propose a framework for exploring knowledge structure. We also present several longitudinal analyses to interpret and visualize the last 20 years of published obesity research data.
Expectations of Recovery after Lumbar Spine Surgery: A Quality Improvement Project to Improve Patient Satisfaction

description: Patients scheduled for lumbar spine surgery have expectations of recovery that can positively or negatively affect their post-operative surgical experience. Pre-surgical counseling that prospectively addresses expectations of recovery can help: (1) direct patient education focused on setting realistic goals; (2) personalize their healthcare experience; and (3) allow for shared decision making. A discussion of patient expectations between the patient and provider is an essential component of the pre-surgical assessment that is often overlooked. The purpose of the project was to determine patient expectations regarding lumbar spine surgery and to implement and evaluate an education program that was designed to better align patient-provider expectations, particularly those with high expectations. The project also involved evaluation of overall satisfaction with the provider and educational intervention. A descriptive cross-sectional analysis of 23 patients scheduled for lumbar spine surgery at a Veterans Affairs Medical Center in the southeast was conducted from June 11, 2015 through September 10, 2015. Using the Hospital for Special Lumbar Spine Surgery Expectations Survey, six patients with the highest expectations of recovery prior to their lumbar spine surgery were identified. An analysis of pre- and post-test expectation survey scores showed a clinically relevant change in scores after the educational intervention. Overall satisfaction with the educational intervention and provider consultation was high. Eighty-six percent of patients indicated that they were strongly satisfied with the information given and felt that the education resulted in reduced distress related to recovery after surgery. The results of this project demonstrates that although patient and provider recovery expectations may initially be discordant, conversations that impart knowledge and understanding of recovery after lumbar spine surgery can influence expectations and effect change.
