description: We give a new, effective proof of the separability of cubically convex-cocompact subgroups of special groups. As a consequence, we show that if $G$ is a virtually compact special hyperbolic group, and $Q\leq G$ is a $K$-quasiconvex subgroup, then any $g\in G-Q$ of word-length at most $n$ is separated from $Q$ by a subgroup whose index is polynomial in $n$ and exponential in $K$. This generalizes a result of Bou-Rabee and the authors on residual finiteness growth and a result of the second author on surface groups.

description: Bourgain and Yehudayoff recently constructed $O(1)$-monotone bipartite expanders. By combining this result with a generalisation of the unraveling method of Kannan, we construct 3-monotone bipartite expanders, which is best possible. We then show that the same graphs admit 3-page book embeddings, 2-queue layouts, 4-track layouts, and have simple thickness 2. All these results are best possible.
Inferring the diffusion coefficient in the heliosheath by time spectra simulations of GCRs in the HelMod framework
Creators: name: , Salvatore
Publisher: name: INFN Open Access Repository
Year: 2023

description: The diffusion of galactic cosmic rays inside the heliosphere is a stochastic process due to the scattering of particles with magnetic irregularities embedded in the solar wind. Our knowledge of the solar wind turbulence nature and dynamics mostly relies on near-Earth and near-Sun observations, therefore the whole turbulence behaviour is not yet understood when moving far away from these sites. Galactic cosmic rays coming from the local interstellar medium enter the heliosphere experiencing, besides diffusive stochastic motion, energy loss and convection. In this work, we model the propagation of particles through the heliosheath, i.e. between ∼ 90 AU and ∼ 120 AU distance from the Sun, solving the Parker Transport Equation using a numerical Monte Carlo technique. We apply a data driven approach based on in-situ observations from Voyager 1 in order to study the solar modulation for different particles and derive their diffusion coefficient rigidity dependence. To do this, the most abundant elements in the solar system are considered together with their corresponding isotopes, leading to the conclusion that the diffusion coefficient, in the energy region from 0.04 to 0.31 GeV/n, is compatible to a rigidity dependence spectral index equal to 1.4.

description: There are over 1 million hospitalizations for heart failure (HF) annually in the United States alone, and a similar number has been reported in Europe. Recent clinical trials investigating novel therapies in patients with hospitalized HF (HHF) have been negative, and the post-discharge event rate remains unacceptably high. The lack of success with HHF trials stem from problems with understanding the study drug, matching the drug to the appropriate HF subgroup, and study execution. Related to the concept of study execution is the importance of including appropriate study sites in HHF trials. Often overlooked issues include consideration of the geographic region and the number of patients enrolled at each study center. Marked differences in baseline patient co-morbidities, serum biomarkers, treatment utilization and outcomes have been demonstrated across geographic regions. Furthermore, patients from sites with low recruitment may have worse outcomes compared to sites with higher enrollment patterns. Consequently, sites with poor trial enrollment may influence key patient end points and likely do not justify the costs of site training and maintenance. Accordingly, there is an unmet need to develop strategies to identify the right study sites that have acceptable patient quantity and quality. Potential approaches include, but are not limited to, establishing a pre-trial registry, developing site performance metrics, identifying a local regionally involved leader and bolstering recruitment incentives. This manuscript summarizes the roundtable discussion hosted by the Food and Drug Administration between members of academia, the National Institutes of Health, industry partners, contract research organizations and academic research organizations on the importance of selecting optimal sites for successful trials in HHF.
Real-Time Siamese Multiple Object Tracker with Enhanced Proposals

description: Maintaining the identity of multiple objects in real-time video is a challenging task, as it is not always feasible to run a detector on every frame. Thus, motion estimation systems are often employed, which either do not scale well with the number of targets or produce features with limited semantic information. To solve the aforementioned problems and allow the tracking of dozens of arbitrary objects in real-time, we propose SiamMOTION. SiamMOTION includes a novel proposal engine that produces quality features through an attention mechanism and a region-of-interest extractor fed by an inertia module and powered by a feature pyramid network. Finally, the extracted tensors enter a comparison head that efficiently matches pairs of exemplars and search areas, generating quality predictions via a pairwise depthwise region proposal network and a multi-object penalization module. SiamMOTION has been validated on five public benchmarks, achieving leading performance against current state-of-the-art trackers. Code available at: https://github.com/lorenzovaquero/SiamMOTION

description: We consider a standard heterogeneous agent model (HAM) that is widely used to analyze price developments in financial markets. The model is linear in log-prices and, in its basic setting, populated by fundamentalists and chartists. As the number of fundamentalists increases and exceeds a specific threshold, oscillations occur whose amplitude might even grow exponentially over time. From an economic perspective to adequately interpret such instability results it is indispensable to ensure that the characteristics and specific building blocks of the HAM are not at odds with the underlying structure of financial markets, in particular the specific trading rules. We expect that in markets with (almost) only fundamentalist traders prices might in the most extreme case oscillate, but never explode. In addition, if limit orders are available, prices should converge monotonically. Finally, if price bubbles occur in financial markets with fundamentalist traders, they should only result from the interactions between fundamentalists and the other traders, e.g., chartists, but not from fundamentalists’ decisions alone. From a mathematical perspective we show that the instability result common to the standard approach can be related to a “hidden” explicit discretization of a stiff ordinary differential equation contained in the model. Replacing this explicit discretization by an implicit one improves the model as it removes this artifact, bringing the model’s prediction in line with standard theory. The refined model still allows for price overshoots, bubbles, and crashes. However, in the implicit model these instabilities are caused by chartists and not by an unintended artifact.

description: We predict intrinsic half-metallicity in armchair boron nitride nanoribbons (ABNNRs) via edge fluorination. The stability, electronic and magnetic properties of bare and edge fluorinated ABNNRs have been systematically analyzed by means of first-principles calculations within the local spin-density approximation (LSDA). The ribbons whose only edge-B atoms passivated with F atoms (i.e., edge-N atoms are un-passivated), regardless of width, are found half-metallic with a half-metal gap of 0.3 eV. A 100 \% spin polarized charge transport across the Fermi level is expected for such ribbons as the spin polarized states are $\sim$0.4 eV more stable than the spin un-polarized states and only single-spin conducting channels are present across the Fermi level owing to the gigantic spin splitting. The existence of half-metallicity is attributed to the localization of electronic charge at bare edge-N atoms as revealed from the analysis of Bloch states and projected density of states (PDOS).The sufficiently large half-metal gap (0.3 eV) with huge difference in the energies ($\sim$ 0.4 eV) of spin polarized and spin compensated states projects these half-metallic ABNNRs as potential candidate for spintronics applications.

description: The Suzaku data of the highly variable magnetar 1E 1547.0$-$5408, obtained during the 2009 January activity, were reanalyzed. The 2.07 s pulsation of the 15--40 keV emission detected with the HXD was found to be phase modulated, with a period of $36.0^{+4.5}_{-2.5}$ ks and an amplitude of $0.52 \pm 0.14$ s. The modulation waveform is suggested to be more square-wave like rather than sinusoidal. While the effect was confirmed with the 10--14 keV XIS data, the modulation amplitude decreased towards lower energies, becoming consistent with 0 below 4 keV. After the case of 4U 0142+61, this makes the 2nd example of this kind of behavior detected from magnetars. The effect can be interpreted as a manifestation of free precession of this magnetar, which is suggested to be oblately deformed under the presence of strong toroidal field of $\sim 10^{16}$ G.

description: We theoretically study two-dimensional exciton-polariton lattices and predict that non-Hermitian topological corner modes can be formed under non-resonant pumping. As a generalization of the non-Hermitian skin effect, all eigenstates are localized at the two corners in our model. This is also a higher dimensional topology compared to other proposals in exciton-polariton systems and we find that it allows propagating signals in the bulk of the system to travel around defects, which is not possible in one-dimensional topological lattices or two-dimensional lattices with Hermitian edge states. Furthermore, as all polariton states are localized away from an excitation spot, the system offers an opportunity for more accurate measurement of the polariton-polariton interaction strength as the pump-induced exciton-reservoir is spatially separated from all polariton states.

Measurement of the Higgs boson width and evidence of its off-shell contributions to ZZ production
Creators: name: CMS Collaboration
Publisher: name: arXiv
Year: 2022
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: Since the discovery of the Higgs boson in 2012, detailed studies of its properties have been ongoing. Besides its mass, its width - related to its lifetime - is an important parameter. One way to determine this quantity is by measuring its off-shell production, where the Higgs boson mass is far away from its nominal value, and relating it to its on-shell production, where the mass is close to the nominal value. Here, we report evidence for such off-shell contributions to the production cross section of two Z bosons with data from the CMS experiment at the CERN Large Hadron Collider. We constrain the total rate of the off-shell Higgs boson contribution beyond the Z boson pair production threshold, relative to its standard model expectation, to the interval [0.0061, 2.0] at 95% confidence level. The scenario with no off-shell contribution is excluded at a $p$-value of 0.0003 (3.6 standard deviations). We measure the width of the Higgs boson as $Γ_{\mathrm{H}}$ = 3.2 $_{-1.7}^{+2.4}$ MeV, in agreement with the standard model expectation of 4.1 MeV. In addition, we set constraints on anomalous Higgs boson couplings to W and Z boson pairs.

description: In this work, we study the jet momentum broadening in an inhomogeneous dense QCD medium. The transverse profile of this nuclear matter is described within a gradient expansion, and we focus on the leading gradient contributions. The leading parton is allowed to interact multiple times with the background through the soft gluon exchanges. We derive the associated final particle distribution using both the GLV opacity series and the BDMPS-Z formalism. We further discuss the modified factorization of the initial and final state effects and its consequences for phenomenological applications in the context of heavy-ion collisions and deep inelastic scattering. Finally, we present the broadening probability (describing the final state effects) in several limiting regimes, and give its numerical estimates for phenomenologically motivated sets of parameters.

description: Non-reciprocal interactions play a crucial role in many social and biological complex systems. While directionality has been thoroughly accounted for in networks with pairwise interactions, its effects in systems with higher-order interactions have not yet been explored as deserved. Here, we introduce the concept of M-directed hypergraphs, a general class of directed higher-order structures, which allow to investigate dynamical systems coupled through directed group interactions. As an application we study the synchronization of nonlinear oscillators on 1-directed hypergraphs, finding that directed higher-order interactions can destroy synchronization, but also stabilize otherwise unstable synchronized states.

description: This paper analyzes the effect of meal regularity on adult obesity. For solving a potential endogeneity problem, a propensity score matching method is applied. BMI, waist and daily energy intake are selected as outcome variables. We set the two hypotheses on the relationship between obesity and eating regular meals or eating breakfast regularly. Analytical results show that the adults who are having regular meals intake more calories than those eating irregular meals, but his or her BMI is lower than those eating irregular meals. And the adults eating regular breakfast are proven to intake more calories than those eating irregular breakfast, but his or her BMI is lower than those eating breakfast irregularly. These results suggest that regular eating is effective in reducing obesity.

description: Demand-Responsive Transport (DRT), almost the same with call-taxis, is operated to protect rural villagers’ mobility rights. Currently its pricing is extemporaneous without reasonable ground. To decide its optimal price and subsidy, this study estimates willingness-to-pay of DRT using the Contingent Valuation Method (CVM), based on the case of Jinan-gun, Jeollabuk-do. The average WTP of DRT per person and trip is ₩4,987 when both bus and DRT are serviced at the same time and ₩5,986 when only DRT is serviced. In addition, how socio-economic variables impact people's willingness-to-pay is explored. The results' implications to economic efficiency and efficient pricing are also examined.

description: A solution of the fractional N-dimensional radial Schrodinger equation with the Deng-Fan potential is investigated by the generalized fractional NU method. The analytical formulas of energy eigenvalues and corresponding eigen functions for the Deng-Fan potential are generated. Furthermore, the current results are applied to several diatomic molecules for the Deng-Fan potential as well as the shifted Deng Fan potential. For both the Deng-Fan potential and its shifted potential, the effect of the fractional parameter on the energy levels of various diatomic molecules is examined numerically and graphically. We found that the energy eigenvalues are gradually improved when the fractional parameter increases. The energy spectra of various diatomic molecules are also evaluated in three-dimensional space and higher dimensions. It is worthy to note that the energy spectrum raises as the number of dimensions increases. In addition, the dependence of the energy spectra of the Deng-Fan potential and its shifted potential on the reduced mass, screening parameter, equilibrium bond length, rotational and vibrational quantum numbers is illustrated. To validate our findings, we estimate the energy levels of the Deng-Fan potential and shifted Deng-Fan potential at the classical case for various diatomic molecules and found that they are entirely compatible with earlier studies.

description: Osmotic demyelination syndrome (ODS) is a non-inflammatory process of the central nervous system caused by extracellular osmotic changes, which leads to oligodendrocyte apoptosis and disruption of myelin sheaths, usually affecting patients with underlying systemic conditions that impose susceptibility to osmotic stress. Description of ODS in patients with non-Hodgkin lymphoma (NHL) is limited to a few case reports. Here, we report a 44-year-old man with NHL that had an incidental diagnosis of ODS. We conducted a literature review of the published cases of ODS in NHL patients from 1959 to 2020, aiming to describe the characteristics of these patients. A total of seven patients were summarized (four men and three women), including our case and six patients from published reports. Risk factors such as weight loss and alcoholism were reported in five (71.4%) patients. Hyponatremia was found in six (85.7%) of the cases, and none of them had overly rapid sodium correction. Four cases were asymptomatic, and diffuse large B-cell lymphoma was the most common subtype of NHL (85.7%). The outcome was favorable in most cases; only two deaths not directly related to ODS were reported. We wish to suggest that systemic and metabolic stress induced by NHL may be associated with the development of central osmotic demyelination, and therefore, NHL may be a novel risk factor for ODS. Clinicians should be aware of ODS in patients with hematological malignancies, even in the absence of traditional risk factors.

We parameterize each slice by a lamination just as in the quadratic case, relying on the techniques of smart criticality previously developed by the authors.

description: Patients present with a differential baseline risk of cancer based on normal and expected variations in genes associated with cancer. The baseline risk of developing cancer is acted on throughout life as the genome of different cells interacts with the environment in the form of exposures (eg, toxins, infections). As genetic damage is incurred throughout a lifetime (directly to DNA sequences or to the epigenome), events are set in motion to progressively disrupt normal cellular pathways toward tumorigenesis. This article attempts to characterize broad categories of genetic aberrations and pathways in a manner that might be useful for the clinician to understand the risk of developing cancer, the pathways that are disrupted, and the potential for molecular-based diagnostics.

description: Neutrinoless double beta decay ($0νββ$) nuclear matrix elements (NME) are the object of many theoretical calculation methods, and are very important for analysis and guidance of a large number of experimental efforts. However, there are large discrepancies between the NME values provided by different methods. In this paper we propose a statistical analysis of the $^{48}$Ca $0νββ$ NME using the interacting shell model, emphasizing the range of the NME probable values and its correlations with observables that can be obtained from the existing nuclear data. Based on this statistical analysis with three independent effective Hamiltonians we propose a common probability distribution function for the $0νββ$ NME, which has a range of (0.45 - 0.95) at 90\% confidence level of, and a mean value of 0.68.

description: Skyrmion lines in metallic chiral magnets carry an emergent magnetic field experienced by the conduction electrons. The inflow and outflow of this field across a closed surface is not necessarily equal, thus it allows for the existence of emergent monopoles. One example is a segment of skyrmion line inside a crystal, where a monopole and antimonopole pair is connected by the emergent magnetic flux line. This is a realization of Dirac string-like excitations. Here we study the dynamics of monopoles in chiral magnets under an electric current. We show that in the process of creation of skyrmion lines, skyrmion line segments are first created via the proliferation of monopoles and antimonopoles. Then these line segments join and span the whole system through the annihilation of monopoles. The skyrmion lines are destroyed via the proliferation of monopoles and antimonopoles at high currents, resulting in a chiral liquid phase. We also propose to create the monopoles in a controlled way by applying an inhomogenous current to a crystal. Remarkably, an electric field component in the magnetic field direction proportional to the current squared in the low current region is induced by the motion of distorted skyrmion lines, in addition to the Hall and longitudinal voltage. The existence of monopoles can be inferred from transport or imaging measurements.

description: Numerical simulations can help solve complex problems. Most of these algorithms are massively parallel and thus good candidates for FPGA acceleration thanks to spatial parallelism. Modern FPGA devices can leverage high-bandwidth memory technologies, but when applications are memory-bound designers must craft advanced communication and memory architectures for efficient data movement and on-chip storage. This development process requires hardware design skills that are uncommon in domain-specific experts. In this paper, we propose an automated tool flow from a domain-specific language (DSL) for tensor expressions to generate massively-parallel accelerators on HBM-equipped FPGAs. Designers can use this flow to integrate and evaluate various compiler or hardware optimizations. We use computational fluid dynamics (CFD) as a paradigmatic example. Our flow starts from the high-level specification of tensor operations and combines an MLIR-based compiler with an in-house hardware generation flow to generate systems with parallel accelerators and a specialized memory architecture that moves data efficiently, aiming at fully exploiting the available CPU-FPGA bandwidth. We simulated applications with millions of elements, achieving up to 103 GFLOPS with one compute unit and custom precision when targeting a Xilinx Alveo U280. Our FPGA implementation is up to 25x more energy-efficient than expert-crafted Intel CPU implementations.

description: Triple negative breast cancer (TNBC) defined as lacking expression of the estrogen receptor, progesterone receptor and HER2, comprises approximately 15% of incident breast cancers and is over-represented among those with metastatic disease. It is increasingly clear that TNBC is heterogeneous and that there are several biologically distinct subtypes within TNBC, in particular the basal-like subtype but also the claudin-low, among others. While the incidence of BRCA mutations across all subsets of breast cancer is quite low (~5%), BRCA mutations are more common among those with TNBC (~20%) and may have therapeutic implications. The general principles guiding the use of chemotherapy and radiation therapy do not differ dramatically between early stage TNBC and non-TNBC. There is a trend, however, to treat TNBC at a lower stage with chemotherapy as this is the only way to systemically reduce recurrence risk. In the metastatic setting, while cytotoxic chemotherapy is the mainstay of treatment for advanced TNBC, there are many promising targeted therapies in development in both the preclinical and early phase clinical trial settings. While the treatment of TNBC remains a challenge, coordinated efforts between clinician/scientist partnerships providing a comprehensive understanding of TNBC genomic, proteomic and other biologic processes may result in individualized therapy for TNBC faster than other subtypes -- driven by both the heterogeneity we know exists within this clinical entity and the intense need for improved treatment.
title: Calculating Effective Degrees of Freedom for Forecast Combinations and Ensemble Models
Creators: name: Younker, James

description: Forecast combinations, also known as ensemble models, routinely require practitioners to select a model from a massive number of potential candidates. Ten explanatory variables can be grouped into 2^1078 forecast combinations, and the number of possibilities increases further to 2^1078+2^1078 if we allow for forecast combinations of forecast combinations. This paper derives a calculation for the effective degrees of freedom of a forecast combination under a set of general conditions for linear models. It also supports this calculation with simulations. The result allows users to perform several other computations, including the F-test and various information criteria. These computations are particularly useful when there are too many candidate models to evaluate out of sample. Furthermore, computing effective degrees of freedom shows that the complexity cost of a forecast combination is driven by the parameters in the weighting scheme and the weighted average of parameters in the auxiliary models as opposed to the number of auxiliary models. This identification of complexity cost contributions can help practitioners make informed choices about forecast combination design.
description: Les combinaisons de prévisions, aussi appelées modèles d’ensemble, obligent régulièrement les praticiens à sélectionner un modèle parmi un grand nombre de modèles potentiels. Dix variables explicatives peuvent être groupées en 2^1078 combinaisons de prévisions, et le nombre de possibilités atteint même 2^1078+2^1078 si l’on tient compte des combinaisons de prévisions des combinaisons de prévisions. Dans cette étude, l’auteur s’attache à calculer les degrés de liberté effectifs d’une combinaison de prévisions en fonction d’un ensemble de conditions générales applicables aux modèles linéaires. Il conforte aussi son calcul par des simulations. Le résultat permet aux utilisateurs d’effectuer plusieurs autres calculs, dont le test de Fisher (test F) et divers critères d’information. Ces calculs sont particulièrement utiles lorsqu’il y a trop de modèles possibles à évaluer hors échantillon. De plus, le calcul des degrés de liberté effectifs montre que le coût de complexité d’une combinaison de prévisions dépend des paramètres du système de pondération et de la moyenne pondérée des paramètres dans les modèles auxiliaires, plutôt que du nombre de modèles auxiliaires. Cette détermination de la contribution du coût de complexité peut aider les praticiens à faire des choix éclairés pour la formation de combinaisons de prévisions.

description: Interactivity is an important concept in the study of online social processes. Two experiments tested how interactivity influenced people’s willingness to comment on social media and their perceptions of a company’s corporate social responsibility (CSR) efforts. Across two operationalizations of interactivity (presence/absence of replies, high/low degree of reference to earlier messages), interactivity led to greater perceived contingency, which led to greater willingness to comment and more positive CSR perceptions. Results advance the interactivity effects model by demonstrating that (a) perceived contingency plays a crucial role in interactivity effects, (b) language intensity moderates the relationship between perceived contingency and willingness to comment, and (c) perceived contingency is fostered only by companies’ interactive messages and not consumers’ interactive messages.

description: The realization of experimental platforms exhibiting one dimensional (1D) quantum phenomena has been elusive, due to their inherent lack of stability, with a few notable exceptions including spin chains, carbon nanotubes and ultracold low-density gasses. The difficulty of such systems in exhibiting long range order is integral to their effective description in terms of the Tomonaga-Luttinger liquid theory. Recently, it has been proposed that bosonic superfluid 4He could realize a 1D quantum system beyond the Luttinger liquid paradigm. Here we describe an experimental observation of this behavior using nanoengineering by preplating a porous material with a noble gas to enhance dimensional reduction. The resulting excitations of the confined 4He are qualitatively different than 3D and 2D superfluid helium, and can be analyzed in terms of a mobile impurity in a Luttinger liquid allowing for the characterization of the emergent quantum liquid. The confined helium system offers the possibility of tuning via pressure - from weakly interacting, all the way to the super Tonks-Girardeau gas of strongly interacting hard-core particles.

On the $k$-limited packing numbers in graphs

description: We give a sharp lower bound on the lower $k$-limited packing number of a general graph. Moreover, we establish a Nordhaus-Gaddum type bound on $2$-limited packing number of a graph. Also, we investigate the concepts of packing number ($1$-limited packing number) and open packing number in graphs with more details. In this way, by making use of the classic result of Meir and Moon (1975) and its total version (2005) we give new sharp upper bounds on domination number and total domination number of trees.

description: We study the Mathias--Prikry and the Laver type forcings associated with filters and coideals. We isolate a crucial combinatorial property of Mathias reals, and prove that Mathias--Prikry forcings with summable ideals are all mutually bi-embeddable. We show that Mathias forcing associated with the complement of an analytic ideal always adds a dominating real. We also characterize filters for which the associated Mathias--Prikry forcing does not add eventually different reals, and show that they are countably generated provided they are Borel. We give a characterization of $ω$-hitting and $ω$-splitting families which retain their property in the extension by a Laver type forcing associated with a coideal.

Sickle-Cell Trait: Novel Clinical Significance

description: There is a long-standing controversy in the literature as to whether sickle-cell trait (SCT) should be viewed as a benign carrier state or as an intermediate disease phenotype. Because SCT is routinely detected by neonatal screening for sickle-cell disease, it becomes imperative that consensus on this issue be achieved in order to provide the best medical advice to affected individuals. The issue of selective screening in the post-neonatal period was thrust into the limelight recently by the National Collegiate Athletic Association’s recommendation that its member colleges and universities test student-athletes to confirm their carrier status if not already known. The stated goal of this recommendation was to prevent exercise-related sudden death in athletes with SCT. We review some of the reported complications of SCT for which new information has emerged, focusing particularly on venous thromboembolism and renal manifestations.
