description: We investigate the potential of the Atacama Large Millimeter/submillimeter Array (ALMA) and the Next Generation Very Large Array (ngVLA) to observe substructures in nearby young disks which are due to the gravitational interaction between disk material and planets close to the central star. We simulate the gas and dust dynamics in the disk using the LA-COMPASS hydrodynamical code. We generate synthetic images for the dust continuum emission at sub-millimeter to centimeter wavelengths and simulate ALMA and ngVLA observations. We explore the parameter space of some of the main disk and planet properties that would produce substructures that can be visible with ALMA and the ngVLA. We find that ngVLA observations with an angular resolution of 5 milliarcsec at 3 mm can reveal and characterize gaps and azimuthal asymmetries in disks hosting planets with masses down to $\approx~5 M_{\oplus}$ $\approx 1 - 5$ au from a Solar-like star in the closest star forming regions, whereas ALMA can detect gaps down to planetary masses of $\approx 20~M_{\oplus}$ at 5 au. Gaps opened by super-Earth planets with masses $\approx 5 - 10 M_{\oplus}$ are detectable by the ngVLA in the case of disks with low viscosity ($α\sim 10^{-5}$) and low pressure scale height ($h \approx 0.025$ au at 5 au). The ngVLA can measure the proper motion of azimuthal asymmetric structures associated with the disk-planet interaction, as well as possible circumplanetary disks on timescales as short as one to a few weeks for planets at $1 - 5$ au from the star.

description: We compute the oblique parameters, including the three new parameters $ V $, $ W $ and $ X $ introduced recently by the Montreal group, for the case of one scalar multiplet of arbitrary weak isospin $ J $ and weak hypercharge $ Y $. We show that, when the masses of the heaviest and lightest components of the multiplet remain constant, but $ J $ increases, the oblique parameter $ U $ and the three new oblique parameters increase like $ J^3 $, while $ T $ only increases like $ J $. For large multiplets with masses not much higher than $ m_Z $, the oblique parameters $ U $ and $ V $ may become much larger than $ T $ and $ S $.

description: This paper reports on the complete mitochondrial (mt) genome of a horseshoe crab, Tachypleus gigas (T. gigas), in Kuala Kemaman, Terengganu, Malaysia. Whole-genome sequencing of hemocyte DNA was performed with Illumina HiSeq system and the generated reads were de novo assembled with ABySS 2.1.5 and reassembled using mitoZ against Carcinoscorpius rotundicauda and Limulus polyphemus, resulting in a contig of 15 Kb. Phylogenetic analysis of the assembled mt genome suggests that the Tachypleus gigas is closely related to Tachypleus tridentatus than to Carcinoscorpius rotundicauda.

description: Abstract

Anemia is a significant public health concern, particularly among pregnant women, due to its impact on maternal and fetal health. This study investigates the prevalence of severe anemia among pregnant women in Dhusamareb District, Somalia, based on hemoglobin (Hb) evaluation from January 2023 to May 2024. The research explores the educational, economic, and nutritional factors contributing to anemia during pregnancy.

Using a cross-sectional study design, data was collected through structured questionnaires and laboratory investigations. The findings indicate that low educational levels, poor dietary intake, and financial constraints significantly contribute to anemia prevalence. Additionally, factors such as inadequate iron supplementation, parasitic infections, and limited access to healthcare services exacerbate the condition. The study also highlights that pregnant women from low socioeconomic backgrounds are more vulnerable to anemia due to insufficient nutrition and poor healthcare access.

The study underscores the need for targeted interventions, including improved maternal nutrition programs, community-based anemia awareness campaigns, and strengthened healthcare services for pregnant women. Recommendations include enhancing iron supplementation programs, increasing access to prenatal healthcare, and promoting balanced diets through educational initiatives. These findings provide valuable insights for healthcare professionals, policymakers, and organizations working to improve maternal health in Somalia.

description: We study the growth of fractal clusters in the Dielectric Breakdown Model (DBM) by means of iterated conformal mappings. In particular we investigate the fractal dimension and the maximal growth site (measured by the Hoelder exponent $α_{min}$) as a function of the growth exponent $η$ of the DBM model. We do not find evidence for a phase transition from fractal to non-fractal growth for a finite $η$-value. Simultaneously, we observe that the limit of non-fractal growth ($D\to 1$) is consistent with $α_{min} \to 1/2$. Finally, using an optimization principle, we give a recipe on how to estimate the effective value of $η$ from temporal growth data of fractal aggregates.

description: We study a model Dyson-Schwinger equation for the quark propagator closed using an {\it Ansatz} for the gluon propagator of the form \mbox{$D(q) \sim q^2/[(q^2)^2 + b^4]$} and two {\it Ansätze} for the quark-gluon vertex: the minimal Ball-Chiu and the modified form suggested by Curtis and Pennington. Using the quark condensate as an order parameter, we find that there is a critical value of $b=b_c$ such that the model does not support dynamical chiral symmetry breaking for $b>b_c$. We discuss and apply a confinement test which suggests that, for all values of $b$, the quark propagator in the model {\bf is not} confining. Together these results suggest that this Ansatz for the gluon propagator is inadequate as a model since it does not yield the expected behaviour of QCD.

description: Learning the structure of Bayesian networks from data is known to be a computationally challenging, NP-hard problem. The literature has long investigated how to perform structure learning from data containing large numbers of variables, following a general interest in high-dimensional applications ("small n, large p") in systems biology and genetics. More recently, data sets with large numbers of observations (the so-called "big data") have become increasingly common; and these data sets are not necessarily high-dimensional, sometimes having only a few tens of variables depending on the application. We revisit the computational complexity of Bayesian network structure learning in this setting, showing that the common choice of measuring it with the number of estimated local distributions leads to unrealistic time complexity estimates for the most common class of score-based algorithms, greedy search. We then derive more accurate expressions under common distributional assumptions. These expressions suggest that the speed of Bayesian network learning can be improved by taking advantage of the availability of closed form estimators for local distributions with few parents. Furthermore, we find that using predictive instead of in-sample goodness-of-fit scores improves speed; and we confirm that is improves the accuracy of network reconstruction as well, as previously observed by Chickering and Heckerman (2000). We demonstrate these results on large real-world environmental and epidemiological data; and on reference data sets available from public repositories.

description: This paper evaluates quantitatively the implications of the preferential tax treatment of debt in the United States corporate income tax code. Specifically, we examine the economic con- sequences of allowing firms to deduct interest expenses from their tax liabilities on financial variables such as leverage, default decisions and credit spreads. We conduct a series of policy experiments in which the tax deductibility of the corporate interest expense is eliminated. As expected, this results in a substantial decrease in the equilibrium level of leverage. However, contrary to conventional wisdom, we find that eliminating interest deductibility results in an increase in the default frequency and average credit spreads in the economy. The intuition for this lies in the fact that this policy change makes external financing more costly, resulting in riskier firms and higher credit spreads.

description: As massive gravity and its extensions offer physically well-defined gravitational theories with a nonzero graviton mass, we present a new extension of the de Rham-Gabadadze-Tolley (dRGT)massive gravity, which is tachyonic massive gravity theory. We firstly introduce the new extension of the dRGT massive gravity, constructed by adding a tachyonic term. We then find the cosmological background equations, and present the analysis of self-accelerating solutions. We examine the tensor perturbations to calculate the dispersion relation of gravitational waves (GWs). In a special case, we consider a constant tachyon potential for the tachyon field, and calculate the equations of motion and self-accelerating solutions. Finally, we investigate the background perturbations, which include tensor, vector, and scalar perturbations in this case. We calculate the dispersion relation of GWs in the FLRW cosmology in a tachyonic massive gravity theory. These analyses provide potential inputs to future applications in cosmology and GWs propagation.

We also show that the Zeilberger-type series $\sum_{k=1}^\infty(3k-1)16^k/(k\binom{2k}k)^3=π^2/2$ has two $q$-analogues with $|q|<1$, one of which is $$\sum_{n=0}^\infty q^{n(n+1)/2} \frac {1-q^{3n+2}} {1-q} \cdot\frac{(q;q)_n^3 (-q;q)_n}{(q^3;q^2)_{n}^3} = (1-q)^2 \frac{(q^2;q^2)^4_\infty}{(q;q^2)^4_\infty}.$$

description: The phosphide-based III-V semiconductors InP, GaP, and In$_{0.5}$Ga$_{0.5}$P are promising materials for solar panels in outer space and radioisotope batteries, for which lifetime is a major issue. In order to understand high radiation tolerance of these materials and improve it further, it is necessary to describe the early stages of radiation damage on fast time and short length scales. In particular, the influence of atomic ordering, as observed e.g. in In$_{0.5}$Ga$_{0.5}$P, on electronic stopping is unknown.We use real-time time-dependent density functional theory and the adiabatic local density approximation to simulate electronic stopping of protons in InP, GaP, and the CuAu-I ordered phase of In$_{0.5}$Ga$_{0.5}$P across a large kinetic energy range.These results are compared to SRIM and we investigate the dependence on the channel of the projectile through the target.We show that stopping can be enhanced or reduced in In$_{0.5}$Ga$_{0.5}$P and explain this using the electron-density distribution. By comparing Ehrenfest and Born-Oppenheimer molecular dynamics, we illustrate the intricate dynamics of a proton on a channeling trajectory.

description: We say that a graph $G=(V,E)$ on $n$ vertices is a $β$-expander for some constant $β>0$ if every $U\subseteq V$ of cardinality $|U|\leq \frac{n}{2}$ satisfies $|N_G(U)|\geq β|U|$ where $N_G(U)$ denotes the neighborhood of $U$. In this work we explore the process of deleting vertices of a $β$-expander independently at random with probability $n^{-α}$ for some constant $α>0$, and study the properties of the resulting graph. Our main result states that as $n$ tends to infinity, the deletion process performed on a $β$-expander graph of bounded degree will result with high probability in a graph composed of a giant component containing $n-o(n)$ vertices that is in itself an expander graph, and constant size components. We proceed by applying the main result to expander graphs with a positive spectral gap. In the particular case of $(n,d,λ)$-graphs, that are such expanders, we compute the values of $α$, under additional constraints on the graph, for which with high probability the resulting graph will stay connected, or will be composed of a giant component and isolated vertices. As a graph sampled from the uniform probability space of $d$-regular graphs with high probability is an expander and meets the additional constraints, this result strengthens a recent result due to Greenhill, Holt and Wormald about vertex percolation on random $d$-regular graphs. We conclude by showing that performing the above described deletion process on graphs that expand sub-linear sets by an unbounded expansion ratio, with high probability results in a connected expander graph.

description: We give an overview and extension of recent results on ergodic random Schrödinger operators for models on $\mathbb{Z}^d$. The operators we consider are defined on combinatorial or metric graphs, with random potentials, random boundary conditions and random metrics taking values in a finite set. We show that normalized finite volume eigenvalue counting functions converge to a limit uniformly in the energy variable, at least locally. This limit, the integrated density of states (IDS), can be expressed by a closed Shubin-Pastur type trace formula. The set of points of increase of the IDS supports the spectrum and its points of discontinuity are characterized by existence of compactly supported eigenfunctions. This applies to several examples, including various periodic operators and percolation models.

We show a dumbbell-shaped in-plane negative MR up to room temperature as well as a large out-of-plane positive MR. MR at three directions is about in a -3%: -1%: 225% ratio at 2 K. Through both the thickness and composition-dependent magnetotransport measurements, we show that the in-plane negative MR is due to the topological phase transition enhanced intersurface coupling near the topological critical point. Our devices suggest the great potential for room-temperature spintronic applications, for example, vector magnetic sensors.

Convex Programming Methods for Global Optimization

subject: FOS: Economics and business

description: We investigate some approaches to solving nonconvex global optimization problems by convex nonlinear programming methods. We assume that the problem becomes convex when selected variables are fixed. The selected variables must be discrete, or else discretized if they are continuous. We provide a survey of disjunctive programming with convex relaxations, logic-based outer approximation, and logic-based Benders decomposition. We then introduce a branch-and-bound method with convex quasi-relaxations (BBCQ) that can be effective when the discrete variables take a large number of real values. The BBCQ method generalizes work of Bollapragada, Ghattas and Hooker on structural design problems. It applies when the constraint functions are concave in the discrete variables and have a weak homogeneity property in the continuous variables.

description: In this article we present an evaluation of the uncertainty in the average number of photoelectrons, which is important for the calibration of photodetectors. We show that the statistical uncertainty depends on light intensity, and on the method of evaluation. For some cases there is optimal light intensity where the accuracy reaches its optimal value with fixed statistics. A method of photoelectron evaluation based on the extraction of pedestal's (zero) probability gives the best accuracy at approximately 1.6 photoelectrons for a noiseless photodetector and shifts out to higher values with the presence of noise. In the general case, estimation of the average number of photoelectrons is biased and might need special consideration.
Velocity dependent dislocation drag from phonon wind and crystal geometry

Publisher: name: arXiv
Year: 2018
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: The mobility of dislocations is an important factor in understanding material strength. Dislocations experience a drag due to their interaction with the crystal structure, the dominating contribution at high stress and temperature being the scattering off phonons due to phonon wind. Yet, the velocity dependence of this effect has eluded a good theoretical understanding. In a previous paper, dislocation drag from phonon wind as a function of velocity was computed from first principles in the isotropic limit, in part for simplicity, but also arguing that macroscopically, a polycrystalline metal looks isotropic. However, since the single crystal grains are typically a few microns up to a millimeter in size, dislocations travel in single crystals and cross boundaries, but never actually see an isotropic material. In this work we therefore highlight the effect of crystal anisotropy on dislocation drag by accounting for the crystal and slip plane geometries. In particular, we keep the phonon spectrum isotropic for simplicity, but dislocations are modeled according to the crystal symmetry (bcc, fcc, hcp, etc.). We then compare to the earlier purely isotropic results, as well as to experimental data and MD simulations where they are available.

In this approach, the most general multidimensional intermittency pattern, associated to a second-order phase transition of the strongly interacting system, is determined, and its relevance to present and future experiments is discussed.

(3) Which stock of money can be controlled best; or stated in another way, how should we define and measure the stock of money that is to be controlled?

description: We have studied the current through a carbon nanotube quantum dot with one ferromagnetic and one normal-metal lead. For the values of gate voltage at which the normal lead is resonant with the single available non-degenerate energy level on the dot, we observe a pronounced decrease in the current for one bias direction. We show that this rectification is spin-dependent, and that it stems from the interplay between the spin accumulation and the Coulomb blockade on the quantum dot. Our results imply that the current is spin-polarized for one direction of the bias, and that the degree of spin polarization is fully and precisely tunable using the gate and bias voltages. As the operation of this spin diode does not require high magnetic fields or optics, it could be used as a building block for electrically controlled spintronic devices.

description: Quark and pole models of nonleptonic decays of charmed baryons are analysed from the point of view of their symmetry properties. The symmetry structure of the parity conserving amplitudes that corresponds to the contribution of the ground-state intermediate baryons is shown to differ from the one hitherto employed in the symmetry approach. It is pointed out that the "subtraction" of sea quark effects in hyperon decays leads to an estimate of $W$-exchange contributions in charmed baryon decays that is significantly smaller than naively expected on the basis of $SU(4)$. An $SU(2)_{W}$ constraint questioning the reliability of the factorization technique is exhibited. Finally, a successful fit to the available data is presented.

description: Understanding the effects of climate change on coral biology and biomineralization is critical for projecting the future of coral reefs. Essential to this understanding are lipid biomolecules which occur both within the tissues and skeletons of corals and fulfil a variety of biological functions. Here we conducted fieldwork and culturing experiments to determine how environmental parameters influence scleractinian coral tissue and skeleton lipid compositions. Our results revealed variations in tissue lipid compositions in cultured Porites spp. due to temperature, genotype, and/or species differences, with no significant effect observed from seawater pCO2. We also observe that elevated temperatures significantly increased total fatty acid and decreased total wax ester contributions to total skeletal lipids within cultured Seriatopora spp. We find a significantly higher contribution of unsaturated fatty acids to the total fatty acid pool at 5 m water depth compared to 25 m in the tissues of Acropora retusa and Pocillopora meandrina collected from a reef site in Moorea. This work together highlights how lipids compositions within reef-building corals change according to their surrounding environment. Skeletal fatty acids in these scleractinian corals were dominated by saturated fatty acids C16:O (palmitic acid) and C18:O (stearic acid), these being the main building blocks of various lipid molecules. We also find a predominance of saturated wax esters C16:0-C14:0, C16:0-C16:0, and C16:0-C18:0 in the skeletons of Seriatopora spp. and Stylophora sp. coral colonies. To explore the role of lipids in coral biomineralization we precipitated aragonite in-vitro under various pH and dissolved inorganic carbon conditions inferred to occur at the coral calcification site, in conjunction with the absence and presence of lipids identified within coral skeletons. Lecithin (a mixture of phospholipids, the primary constituents of biological membranes) significantly inhibited aragonite precipitation and altered the morphology of the aragonite crystals produced. Stearic acid and cholesterol had no significant effects on precipitation rates, nor on aragonite structure and morphology. This research demonstrates that coral lipids are influenced by the environment and that skeletal lipids may be involved in controlling the formation of coral skeletons. Given that future climate change scenarios are likely to increase seawater temperatures and pCO2, potential variations in coral tissue and skeletal lipid compositions as observed in this research could affect the ability of reef-building corals' CaCO3 skeletons to withstand future climate scenarios.

description: Introduction: With frailty a worldwide concern in a rapidly expanding ageing population, proactive approaches to the management and identification of frailty are recommended to help reduce hospitalisations and adverse outcomes. Yet, there is lack of evidence for frailty screening and rehabilitation of adults in an Irish post-acute rehabilitation setting.
Aims and Objective: The primary aim of this study was to compare clinicians’ appraisal and patients’ subjective appraisal of frailty and explore their association with each other and with post-acute rehabilitation outcomes.
Methods: In a prospective cohort observational study in Peamount Healthcare from Oct. 2019-Feb. 2020 32 participants were assessed on admission and discharge. Frailty was measured through clinicians’ appraisal using the Clinical Frailty Scale (CFS) and patients’ subjective appraisal using the Identification of Seniors at Risk Questionnaire (ISAR). Rehabilitation outcomes were measured using the Timed Up and Go (TUG), the Elderly Mobility Scale (EMS) and the Euro-Qol 5D (EQ-5D).
Results: Mean age of participants was 82.66 (±SD 8.31) years. There was no significant difference in the level of frailty reported by clinicians and patients (81.3% vs 84.4%) and no association was found between the ISAR and CFS. Significant improvements were noted in the TUG (p<0.001) the EMS (p<0.001), left grip strength (p=0.05), EQ5D Visual Analogue Scale (p=0.002) and in EQ5D domains except anxiety/depression. A relationship was observed between clinicians’ rating of frailty on admission with measures of activity limitations on discharge with a strong positive association found with TUG (p<0.001) on discharge and a strong negative association with the EMS (p<0.001) on discharge. Little association was noted between levels of impairment and participation restriction. Moderate to strong relationships were found between patients’ frailty appraisals on admission with measures of quality of life on discharge with no associations noted with levels of impairment and activity limitation.
Conclusion: The association of levels of frailty with rehabilitation outcomes varied by method of frailty appraisal used. Both methods provide different yet potentially complementary information in relation to rehabilitation outcomes.
Implications of Findings: This research found improvements in frail older adults following post-acute rehabilitation, however there was variability in levels of frailty in this setting depending on the frailty screening measure used.

A numerical study of Penrose-like inequalities in a family of axially symmetric initial data

description: Our current picture of black hole gravitational collapse relies on two assumptions: i) the resulting singularity is hidden behind an event horizon -- weak cosmic censorship conjecture -- and ii) spacetime eventually settles down to a stationarity state. In this setting, it follows that the minimal area containing an apparent horizon is bound by the square of the total ADM mass (Penrose inequality conjecture). Following Dain et al. 2002, we construct numerically a family of axisymmetric initial data with one or several marginally trapped surfaces. Penrose and related geometric inequalities are discused for these data. As a by-product, it is shown how Penrose inequality can be used as a diagnosis for an apparent horizon finder numerical routine.

description: Information extraction from textual documents such as hospital records and healthrelated user discussions has become a topic of intense interest. The task of medical concept coding is to map a variable length text to medical concepts and corresponding classification codes in some external system or ontology. In this work, we utilize recurrent neural networks to automatically assign ICD-10 codes to fragments of death certificates written in English. We develop end-to-end neural architectures directly tailored to the task, including basic encoder-decoder architecture for statistical translation. In order to incorporate prior knowledge, we concatenate cosine similarities vector among the text and dictionary entry to the encoded state. Being applied to a standard benchmark from CLEF eHealth 2017 challenge, our model achieved F-measure of 85.01% on a full test set with significant improvement as compared to the average score of 62.2% for all official participants approaches.

A Comprehensive Study of Leptoquark Bounds

Year: 1993
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We make a comprehensive study of indirect bounds on scalar leptoquarks that couple chirally and diagonally to the first generation by examining available data from low energy experiments as well as from high energy e+ e- and p pbar accelerators. The strongest bounds turn out to arise from low energy data: For leptoquarks that couple to right--handed quarks, the most stringent bound comes from atomic parity violation. For leptoquarks that couple to left--handed quarks, there are two mass regions: At low masses the bounds arise from atomic parity violation or from universality in leptonic pi decays. At masses above a few hundred GeV's, the dominant bounds come from the FCNC processes that are unavoidable in these leptoquarks: The FCNC bound of the up sector, that arises from D-Dbar mixing, combines with the FCNC bounds from the down sector, that arise from rare K decays and K-Kbar mixing, to a bound on the flavour CONSERVING coupling to the first generation. The bounds restrict leptoquarks that couple with electromagnetic strength to lie above 600 GeV or 630 GeV for leptoquarks that couple to RH quarks, and above 1040 GeV, 440 GeV, and 750 GeV for the SU(2)_W scalar, doublet and triplet leptoquarks that couple to LH quarks. These bounds are considerably stronger than the first results from the direct searches at HERA. Our bounds also already exclude large regions in the parameter space that could be examined by various methods proposed for indirect leptoquark searches.

Subjects: ontology engineering components; living document

description: The present report is the first submitted iteration of a living document that will describe progress and evolvement of the AGINFRA PLUS ontology engineering components, i.e. the services that will be incorporated in the overall AGINFRA PLUS architecture and serve the conceptualization design, requirements of the involved research communities.
 The current version of the deliverable focuses on the installation and deployment of prominent ontology engineering frameworks that will serve as the baseline for producing the final AGINFRA PLUS ontology engineering components, tailored to the core needs reported by the user groups active within the project and adhering to the requirements of the specified AGINFRA PLUS use cases.
 It is expected that, as the use cases are refined and executed, the components will be accordingly updated and extended. Additionally, general developments to the used baseline tools will be monitored and adopted if suitable for the purposes of AGINFRA PLUS. To this end, the report is treated as a living document, with regular submission to the EC of versions that report on significant changes in the ontology engineering prototypes.

description: We derive the fully differential cross section of the Higgs-strahlung process $f \bar{f} \to Z \to Z (\to f_Z \bar{f}_Z) X (\to f_X \bar{f}_X)$, where $f$, $f_Z$, and $f_X$ are arbitrary fermions and $X$ is a spin-zero particle with arbitrary couplings to $Z$ bosons and fermions. This process with $f = e$ and $X = h$ ($h$ denotes the Higgs boson) is planned to be measured at the ILC to put constraints on the couplings $g_1$, $g_2$, $g_3$ of the Higgs boson to $Z$ bosons. Using the obtained fully differential cross section, we define observables measurement of which yields the tightest constraints on the couplings. Explicit dependences of these observables on $g_i$ are derived.
