description: The discovery of extremely zirconium- and lead-rich surfaces amongst a small subgroup of hot subdwarfs has provoked questions pertaining to chemical peculiarity in hot star atmospheres and about their evolutionary origin. With only three known in 2014, a limited search for additional `heavy-metal' subdwarfs was initiated with the Subaru telescope. Five hot subdwarfs having intermediate to high surface enrichment of helium were observed at high-resolution and analyzed for surface properties and abundances. This paper reports the analyses of four of these stars. PG1559+048 and FBS 1749+373, having only intermediate helium enrichment, show strong lines of triply ionized lead. PG1559+048 also shows a strong overabundance of germanium and yttrium. With more helium-rich surfaces, Ton 414 and J17554+5012, do not show evidence of heavy-metal enrichment. This limited survey suggests that extreme enrichment of `heavy metals' by selective radiative levitation in hot subdwarf atmospheres is suppressed if the star is too helium-rich.

description: This study demonstrates a method to calculate the economic value of the loss of a highly valued ecosystem service—the provision of recreational fishing—across a multi-state assessment region. We estimated annual freshwater fishing expenditures foregone from degraded conditions in wadeable streams that are potential habitat to one or more of four sportfish species. Using probability-based federal surveys for data on sportfish presence, we developed range models for the four species in the mountainous portions of four U.S. mid- Atlantic states based on geophysical stream variables unrelated to habitat condition. From these models, we determined the proportion of the wadeable stream resource (44.2%) that could potentially host sportfish and allocated an estimate of annual regional freshwater fishing expenditures (US$826 million) from the National Survey of Fishing, Hunting, and Wildlife- Associated Recreation to these stream segments. We attributed the absence of sportfish in these segments to stream degradation; an additional US$239 million was estimated as lost freshwater fishing expenditures. These figures suggest a considerable annual economic incentive for stakeholders to restore and protect stream habitat for the maintenance of sport fisheries. This method is readily transferable to other U.S. regions where long-term surveys that collect metrics linked to ecosystem services are in place.

description: To elucidate the role of environmental conditions in molecular-level dynamics and to study their impact on macroscopic brain tumor growth patterns, the expression of the genes Tenascin C and PCNA in a 2D agent-based model for the migratory trait is calibrated using experimental data from the literature, while the expression of these genes for the proliferative trait is obtained as the model output. Numerical results confirm that the gene expression of Tenascin C is consistently higher in the migratory glioma cell phenotype and show that the expression of PCNA is consistently higher among proliferating tumor cells. Furthermore, detrended fluctuation analysis (DFA) suggests that for prediction purposes, the simulated gene expression profiles of Tenascin C and PCNA that were determined separately for the migrating and proliferating phenotypes exhibit lesser predictability than those of the phenotypic mixture combining all viable tumor cells typically found in clinical biopsies.

description: Background Hospital Information System (HIS) was introduced by the Ministry of Health (MOH) Malaysia to improve hospital information management. A timely and accurate data aids in facilitating decision-making processes. HIS monitoring and evaluation activities revealed issues in data quality, particularly data completeness. This study aims to explore the data completeness issue in HIS. *The assessment focused on the “structured data” (i.e. data in the database field) instead of “unstructured data” (i.e. data in free text form). Methods [Refer to Poster]. Results [Refer to Poster]. Discussion / Conclusion Data completeness is a vital issue to be addressed, with national plans for electronic health record initiative to be implemented in the future. Advancements in technology should be considered to be used to improve the data entry process among implementers, e.g. voice-to-text to assist with data entry during ward rounds. There should also be more flexibility in system configuration to allow for verification and validation processes to be in place to fulfil the quality standard requirements.
title: COVID-19 calls for Mathematics. Part 2 : interleukin IL-6 and myo-Inositol, suicide-substrate enzyme inhibitors
Creators: name: Mascia, Corrado
Publisher: name: Organisms. Journal of Biological Sciences
Year: 2020

description: Interleukin IL-6 is a cytokine produced in response to various types of damage (infections, tissue injuries, autoimmune diseases, ...) whose action contributes to host defense through stimulation of acute phase responses and immune reactions. However, experimental data show that high concentration levels of interleukin IL-6, and the subsequent inflammatory cascade induced into the organisms, could lead to several complications, such as organs progressive deterioration. The abnormal release of interleukin IL-6 is also a consequence of SARS-CoV-2 virus contagion, usually causing interstitial pneumonia and respiratory failure, which appear to be the source of decease in most of patients. Tocilizumab and myo-Inositol are two possible remedies proposed in the clinical literature to contrast the uncontrolled synthesis of interleukin IL-6, although the former exhibits non negligible collateral effects, differently from the latter. For this reason, the mathematical investigation of myo-Inositol interaction with other relevant substances involved in the SARS-CoV-2 could support the bio-medical research in determining, the optimal doses and administration timing necessary to minimize damages, in order to support the clinical results. The preliminaries of this approach are the subject of this article. Moreover, because a vaccine against the SARS-CoV-2 virus will not be available shortly, we con- sider another possible pharmacological strategy to contrast its activity. There exist several candidate medicines which may inhibit infection and replication of SARS-CoV-2, and we focus our attention on the process of enzymatic inhibition through mechanism-based enzyme inactivators. The so-called suicide- substrate strategies constitute a fascinating area of interdisciplinary research. We explain the procedure to represent mathematically how a hypothetical drug would act to inhibit the essential enzymes used by the SARS-CoV-2 virus to replicate and spread. Considering the biological aspects and the mathematical applications presented in this article, the more relevant questions which arise are: 1) does the design of these drugs deserve a more detailed investigation? Could they be a viable alternative to the strategy of massive vaccine campaign against the SARS-CoV-2 virus?

We review how common nuclear star clusters are in galaxies of different masses and types, and then discuss the typical properties of NSCs. We close by discussing the formation of NSCs, and how a picture is emerging of different formation mechanisms being dominant in lower and higher mass galaxies.

description: We show that the action of Einstein's gravity with a scalar field coupled in a generic way to spacetime curvature is invariant under a particular set of conformal transformations. These transformations relate dual theories for which the effective couplings of the theory are scaled uniformly. In the simplest case, this class of dualities reduce to the S-duality of low-energy effective action of string theory.

A Potentially Detectable Gamma-Ray Line in the Fermi Galactic Center Excess -- In Light of One-Step Cascade Annihilations of Secluded (Vector) Dark Matter via the Higgs Portal

description: We show the presence of a potentially detectable gamma-ray line in the Fermi Galactic center excess in light of the secluded (vector) dark matter (DM) model in which the hidden scalar, nearly degenerate with DM in mass, mediates the interaction of the secluded DM with the Standard Model (SM) due to its mixing with the SM Higgs. We find that the parameter region $m_X\in[60, 132]$ GeV can provide a good fit to the Fermi Galactic center gamma-ray excess spectrum, appearing a prominent gamma-ray line with the energy $\in [30, 66]$ GeV. The best fit gives $m_X\simeq m_S \simeq 86$ GeV with a $p$-value$\, =0.42$, so that the resultant gamma-ray line, arising from the decay of the scalar mediator into $γγ$, peaks at 43 GeV. We derive constraints on the annihilation cross section from the Fermi-LAT gamma-ray line search, gamma-ray observations of the Fermi-LAT dwarf spheroidal galaxies, and Planck cosmic microwave background measurement. For the secluded vector DM model, the parameter space constrained by the current XENON1T and future LUX-ZEPLIN is shown. Finally, for the mixing angle between the Higgs sectors, we discuss its lower bound, which is required by the big bang nucleosynthesis constraint and relevant to the hidden sector decoupling temperature.

description: The Supplemental Nutrition Assistance Program (SNAP) is a federal program that provides assistance to low- and no-income people in the United States. Its aim is to increase individuals’ food-purchasing power and improve the nutritional content of their diet. We employed recent advances in Bayesian spatial econometric modeling to determine the appropriate model for drawing inferences about the percentage of SNAP recipients in Appalachia. We found that there is significant spatial dependence justifying the use of spatial econometric methods. We also examined how changes in an independent variable affect the dependent variable for orders of neighbors over space.

description: Much of the current discussion on factors that influence entrepreneurial activity focuses on availability of human, social, and financial capitals, regional economic conditions, and dynamics of population. We discuss social attitudes toward entrepreneurship and how attitudes may influence entrepreneurial activity. We analyze telephone survey questions designed to gauge attitudes towards community entrepreneurship. High school entrepreneurship career exploration and positive spin-offs from locally-owned business achieved the highest level of support. Both individual- and community-level variables are significantly associated with attitudes toward entrepreneurship. For example, black ethnicity and Detroit residency held positive association with support for high school entrepreneurship curricula. There is statistically significant regional variation in attitudes beyond what traditional regressors can explain, indicating that such attitudes are best measured directly, not estimated. Our results provide a step towards generating benchmarks for communities wishing to employ policies that encourage a shift in entrepreneurial attitudes.

description: Requiring the two-Higgs-doublet model II to accommodate the 3$σ$ deviation in the muon anomalous magnetic moment imposes specific constraints on the Higgs spectrum. We analyze the combination of all the relevant, available, constraints on the model parameter space. The use of constraints from $b\to s γ$, the precision electroweak measurements of $R_b$, and the $ρ$ parameter, together with exclusions from direct searches at LEP, give extremely severe restrictions on the model parameters. That is "almost enough" to kill the model altogether. The exclusion would be even stronger if the direct searches can be optimized to complement the other constraints, as will be discussed in details in this work.

description: Gyrosigma baculum Herwig & Sterrenburg, sp. nov. (Figs 24–27)
Valve linear, 82–92 µm long, 5.5–6.0 µ wide, transverse striae circa 18–19 in 10 µm, longitudinal striae circa 35–37 in 10 µm, raphe sternum staff-shaped in its apical portion.
 Type:— ITALY, Cala Gonone, Sardinia (BRM ZU 8 /35!, holotype, coordinates 7.4 East, 4.6 South = Fig. 24; Fig 25 is another specimen from the same slide, isotype; collection Herwig, isotype; collection Sterrenburg # 712, isotype).
Valves very delicate, 82–92 µm long, 5.5–6.0 µm wide, practically parallel-sided and straight for most of their length, becoming sigmoid near acute apex. Raphe sternum straight except near apices, where it first curves to dorsal side and then recurves on a strongly eccentric and sigmoid course. Striation (Fig. 26): transverse striae circa 18–19 in 10 µm, longitudinal striae circa 35–37 in 10 µm, becoming irregular at the apices (Fig. 27). No hyaline central area visible, central raphe node minute and elongated.
 Etymology: —The specific epithet baculum (“staff”) is chosen to describe the typical reversed curvature of the raphe sternum at the apices.
 Habitat:—Littoral-marine, benthic.
 Distribution:— Type locality only.
 Observations:— Gyrosigma baculum differs from G. tenuissimum in two independent characters: the different course of the raphe sternum and stria density. Gyrosigma baculum somewhat resembles Gyrosigma uncinatum Ricard (1975: 209, fig. 3) in valve contour and raphe sternum course but G. uncinatum has much coarser (15 in 10 µm) transverse striae, a value incompatible with the stria density of G. baculum. No type specimens for Gyrosigma uncinatum have been deposited in PC. No specimens have been isolated for G. baculum for SEM examination as it is very rare in the type material, but the LM findings of raphe sternum course and stria densities already permit separation from the described species.

Remarks. Several records exist of C. insculpta in Singapore, including skeletal remains found on the shore of MR (Ng & Lim 2010) and TQ (Kwan 2015), and from live individuals observed at Eco-Lake at SBG (Kwan 2015; Muhammad Assiddiq 2015) and MR (Baker 2017). A live individual was seen being attacked by otters at Bishan Park on 27 February 2018, and a dead individual was photographed being eaten by a V. salvator at SBG on 12 September 2021 (Kow 2021). A dead, bloated specimen found at Marina Barrage on 13 November 2020 indicates that several individuals kept as pets in Singapore have been abandoned by their owners (Foo 2020). Since this individual was large (ca. 1.2 m), it is not known if the individual was released at its large size or attained that size in the wild after being released. Carettochelys insculpta is native to Papua Indonesia, Papua New Guinea, and Australia (TTWG 2021). In the 1990s, hatchlings were heavily imported for the pet trade (Goh & O’Riordan 2007; Ng & Lim 2010).

description: The study of molecular dynamics simulations is largely facilitated by analysis and visualization toolsets. However, these toolsets are often designed for specific use cases and those only, while scripting extensions to such toolsets is often exceedingly complicated. To overcome this problem, we designed a software application called AViS which focuses on the extensibility of analysis. By utilizing the dataflow programming (DFP) paradigm, algorithms can be defined by execution graphs, and arbitrary data can be transferred between nodes using visual connectors. Extension nodes can be implemented in either Python, C++, and Fortran, and combined in the same algorithm. AViS offers a comprehensive collection of nodes for sophisticated visualization state modifications, thus greatly simplifying the rules for writing extensions. Input files can also be read from the server automatically, and data is fetched automatically to improve memory usage. In addition, the visualization system of AViS uses physically-based rendering techniques, improving the 3D perception of molecular structures for interactive visualization. By performing two case studies on complex molecular systems, we show that the DFP workflow offers a much higher level of flexibility and extensibility when compared to legacy workflows. The software source code and binaries for Windows, MacOS, and Linux are freely available at https://avis-md.github.io/.

description: The Standard Model provides an excellent description of the observables measured at high energy lepton and hadron colliders. However, measurements of the forward-backward asymmetry of the bottom quark at LEP suggest that the effective coupling of the right-handed bottom quark to the neutral weak gauge boson is significantly different from the value predicted by the Standard Model. Such a large discrepancy may be the result of a mixing of the bottom quark with heavy mirror fermions with masses of the order of the weak scale. To be consistent with the precision electroweak data, the minimal extension of the Standard Model requires the presence of vector-like pairs of SU(2) doublet and singlet quarks. In this article, we show that such an extension of the Standard Model is consistent with the unification of gauge couplings and leads to a very rich phenomenology at the Tevatron, the B-factories and the LHC. In particular, if the Higgs boson mass lies in the range 120 GeV $\simlt m_h \simlt 180$ GeV, we show that Run II of the Tevatron collider with 4--8 fb$^{-1}$ of integrated luminosity will have the potential to discover the heavy quarks, while observing a 3-$σ$ evidence of the Higgs boson in most of the parameter space. We also discuss the effects on the time dependent CP-asymmetry in $B \to ϕK_s$ decays.

description: While the Bureau has a wide involvement in fisheries economics, it sees itself as best contributing in the area of applied economic analysis. An example is given of research in the field of fisheries management, which has to take account of a number of complex biological and economic relationships. Frequently, management decisions have to be made with limited information and inadequate understanding of the longer term implications. a linear programming model is outlined which incorporates the underlying biological and technical relationships in the norther prawn fishery and which allows the effects of management options to be simulated.

description: We address the problem of predicting the leading political ideology, i.e., left-center-right bias, for YouTube channels of news media. Previous work on the problem has focused exclusively on text and on analysis of the language used, topics discussed, sentiment, and the like. In contrast, here we study videos, which yields an interesting multimodal setup. Starting with gold annotations about the leading political ideology of major world news media from Media Bias/Fact Check, we searched on YouTube to find their corresponding channels, and we downloaded a recent sample of videos from each channel. We crawled more than 1,000 YouTube hours along with the corresponding subtitles and metadata, thus producing a new multimodal dataset. We further developed a multimodal deep-learning architecture for the task. Our analysis shows that the use of acoustic signal helped to improve bias detection by more than 6% absolute over using text and metadata only. We release the dataset to the research community, hoping to help advance the field of multi-modal political bias detection.

description: We built three models for the gravitational field of the Galactic bar. These models are an inhomogeneous ellipsoid, an inhomogeneous prolate spheroid, and a superposition of four inhomogeneous ellipsoids. Among the three models, the superposition provides our best approximation to the observed boxy mass distribution of the Galactic bar. Adding the bar component to an axisymmetric Galactic model, we have calculated stellar midplane orbits and orbits of some globular clusters with known kinematical data. For all models we find a secular dispersion effect upon the orbital energy and angular momentum, as measured in the Galactic inertial frame. This effect might be relevant to explain the orbital prograde-retrograde distribution of globular clusters. For the stellar kinematics, we study the connection between the sense of orbital motion in the midplane and the onset of chaos in the presence of the bar. In the inner region of the bar, chaos is induced by an axisymmetric central component (bulge) and it arises in orbits that change its orbital sense from prograde to retrograde and vice versa as seen from an inertial reference frame. Outside the bar region, chaos appears only in prograde orbits. Our results concerning such connection are consistent and extend those obtained for midplane orbits in the presence of only a spiral pattern in the axisymmetric Galactic model.

description: We investigate the effects of extended multi-year light curves (9-year photometry and 5-year spectroscopy) on the detection of time lags between the continuum variability and broad-line response of quasars at z>~1.5, and compare with the results using 4-year photometry+spectroscopy presented in a companion paper. We demonstrate the benefits of the extended light curves in three cases: (1) lags that are too long to be detected by the shorter-duration data but can be detected with the extended data; (2) lags that are recovered by the extended light curves but missed in the shorter-duration data due to insufficient light curve quality; and (3) lags for different broad line species in the same object. These examples demonstrate the importance of long-term monitoring for reverberation mapping to detect lags for luminous quasars at high-redshift, and the expected performance of the final dataset from the Sloan Digital Sky Survey Reverberation Mapping project that will have 11-year photometric and 7-year spectroscopic baselines.

Personalized and Weakly Supervised Learning for Parkinson's Disease Symptom Detection

description: Parkinson's Disease (PD) is a neurodegenerative disorder that a ffects approximately one million Americans. Medications exist to manage the symptoms, but doctors must periodically adjust dosage level and frequency as a patient's disease progresses. These adjustments are typically based on observations made during short clinic visits, which provide an incomplete picture of a patient's daily quality
of life. To provide a more accurate assessment of a patient's at-home experience, this thesis explores the use of wearable accelerometers for monitoring PD in the wild. A central challenge of this application is human variability, which makes it di fficult for algorithms to generalize to \unseen" subjects who were not in the training set. This thesis investigates two major approaches to address this issue:
(1) strati ed algorithms for learning from in-the-wild data, and (2) personalization algorithms to actively adjust for human variability. A major challenge with in-the-wild data collection is obtaining labels of tremor symptoms. We developed a data collection protocol in which subjects
used a cellphone app to log the approximate ([0-33%], [33-66%], or [66-100%]) amount of tremor experienced within short time segments and collected in-the wild
data from six PD patients. We call these approximate percentages strati ed labels, and we present a novel strati ed weakly supervised learning technique that bene fits from labels with this structure. Experiments demonstrated that this
new technique leads to higher performance on this dataset compared to standard weakly supervised learning algorithms. Furthermore, strati ed weakly supervised
algorithms performed better on in-the-wild data than fully supervised algorithms trained on accurately labeled laboratory data. These fi ndings suggest that collecting
strati ed labels from each subject in the wild is more eff ective than collecting accurate labels from other subjects in the laboratory. In summary, strati ed learning provides a practical and effi cient method for collecting weak labels in the-
wild that greatly improves accuracy of person-specific PD tremor detection. This thesis also explores several unsupervised personalization algorithms, which either reweight the training data to align its distribution with the test data or learn a regression from distributions to classi ers. We extended these personalization algorithms to the multiclass scenario. In our dataset, the personalization
algorithms demonstrated modest improvement over non-personalized algorithms. We further analyzed the behavior of these algorithms with synthetic data, gaining insights into their limitations when learning appropriate weights. We addressed this issue by developing new constraints to the cost function, which improved performance on synthetic data, and experimented with global optimization.

description: We analyse a set of cosmological magneto-hydrodynamic simulations of the formation of Milky Way-mass galaxies identified to have a prominent radially anisotropic stellar halo component similar to the so-called "Gaia Sausage" found in the Gaia data. We examine the effects of the progenitor of the Sausage (the Gaia-Enceladus-Sausage, GES) on the formation of major galactic components analogous to the Galactic thick disc and inner stellar halo. We find that the GES merger is likely to have been gas-rich and contribute 10-50$\%$ of gas to a merger-induced centrally concentrated starburst that results in the rapid formation of a compact, rotationally supported thick disc that occupies the typical chemical thick disc region of chemical abundance space. We find evidence that gas-rich mergers heated the proto-disc of the Galaxy, scattering stars onto less-circular orbits such that their rotation velocity and metallicity positively correlate, thus contributing an additional component that connects the Galactic thick disc to the inner stellar halo. We demonstrate that the level of kinematic heating of the proto-galaxy correlates with the kinematic state of the population before the merger, the progenitor mass and orbital eccentricity of the merger. Furthermore, we show that the mass and time of the merger can be accurately inferred from local stars on counter-rotating orbits.

description: A collective treatment of the I=0 scalar mesons below 2 GeV [sigma (550), f0(980), f0(1370), f0(1500) and f0(1710)] in a non-linear chiral Lagrangian framework that is constrained by the mass and the partial decay widths of the I=1/2,1 scalars [kappa(900), K0*(1430), a0(980) and a0(1450)] is presented. The sub-structure of these states in terms of two and four quark components, as well as a glueball component is explored, and its correlation with the mass of f0(1370) is studied. Consistency with the available experimental data suggests that the sigma(550) is dominantly a non-strange four-quark state, whereas the sub-structure of other I=0 states are sensitive to the input mass of f0(1370). This investigation estimates the scalar glueball mass in the range 1.47--1.64 GeV.

description: Recent studies using apparent consumption data have identified changes in relative prices, incomes and advertising levels as the primary factors underlying the observed decline in demand for red meat during the period 1964-84. In those studies, beef and veal, lamb chicken and pork were treated as homogeneous goods with single prices. Additional information can be obtained if each of these meats is treated as a heterogeneous aggregate of commodities. Cuts of beef, veal and lamb were grouped into a set of broad price categories. Changes that have occurred in quality and quantity choice within these categories were analysed, and factors affecting these choices were identified. For each category, cross-sectional elasticities were calculated for quantity demand with respect to own price and for quality and quantity with respect to income. In addition, detailed information was obtained on the effect of demographic factors on the demand for each of these categories of meat. It was found that changes in prices, and to a minor extent demographic factors, have contributed to the decline in consumption, and that consumers have altered their quality choices among the different groupings of meat cuts over the period. It cannot be concluded, however, that consumers have traded off quality against quantity over the period.
