Membership Determination of van den Bergh Open Clusters vdB92, vdB146 (NGC 7129) and vdB150

In this paper we study some van den Bergh open clusters combining photometry and astrometry. A model which analyses the proper motion distribution and the stellar density is applied to find the kinematic parameters and stellar membership in the region of the open clusters vdB92, vdB146 (NGC 7129) and vdB150. The astrometric data are obtained from UCAC4 catalogue. The centre coordinates, the components of mean proper motion, the angular diameter and the astrometric members are reported, taking the following values: for vdB92: α=105.97281°±0.13113°, δ=−11.57814°±0.10575°, μαcosδ=−3.46±0.19mas/yr,μδ=1.27±0.19mas/yr, 34', 60 members; for vdB146: α=325.78423°±0.15297°, δ=66.13575°±0.02907°, μαcosδ=−2.71±0.25mas/yr, μδ=−3.32±0.25mas/yr, 9', 5 members; and for vdB150: α=332.22519°±0.06074°, δ=73.40232°±0.0. 07789°, μαcosδ=3.07±0.90mas/yr, μδ=4.65±0.90mas/yr, 15', 7 members. The incidence of the proper motion errors in the determination of the cluster parameters and of the stellar membership is analysed and it is found that they do not significantly change. We finally compare the astrometric members with the photometric ones given in the literature.
A review of multimodel superensemble forecasting for weather, seasonal climate, and hurricanes

This review provides a summary of work in the area of ensemble forecasts for weather, climate, oceans, and hurricanes. This includes a combination of multiple forecast model results that does not dwell on the ensemble mean but uses a unique collective bias reduction procedure. A theoretical framework for this procedure is provided, utilizing a suite of models that is constructed from the well‐known Lorenz low‐order nonlinear system. A tutorial that includes a walk‐through table and illustrates the inner workings of the multimodel superensemble's principle is provided. Systematic errors in a single deterministic model arise from a host of features that range from the model's initial state (data assimilation), resolution, representation of physics, dynamics, and ocean processes, local aspects of orography, water bodies, and details of the land surface. Models, in their diversity of representation of such features, end up leaving unique signatures of systematic errors. The multimodel superensemble utilizes as many as 10 million weights to take into account the bias errors arising from these diverse features of multimodels. The design of a single deterministic forecast models that utilizes multiple features from the use of the large volume of weights is provided here. This has led to a better understanding of the error growths and the collective bias reductions for several of the physical parameterizations within diverse models, such as cumulus convection, planetary boundary layer physics, and radiative transfer. A number of examples for weather, seasonal climate, hurricanes and sub surface oceanic forecast skills of member models, the ensemble mean, and the superensemble are provided.
Elastic constants of polycrystals with generally anisotropic crystals

A homogenization model is developed that describes the effective elastic constants of polycrystalline materials with constituent crystallites of general anisotropy (triclinic symmetry). The model is solved through an iterative technique where successive iterations improve the estimates of the polycrystal's elastic constants. Convergence of the solution provides the self-consistent elastic constants, which are the polycrystal's elastic constants resulting from continuity between local and far-field stress and strains. Iterative solutions prior to convergence are the bounds on the elastic constants including the Voigt-Reuss and Hashin-Shtrikman bounds. The second part of the article establishes a formal link between the present model and single-crystal elastic anisotropy. An analysis from a dataset containing 2176 inorganic crystalline compounds, spanning all crystallographic symmetries, is provided. The role of elastic anisotropy and related properties such as crystalline structure and elastic stability ar.
SYMMETRY OF SOLUTIONS TO SEMILINEAR ELLIPTIC EQUATIONS

In this paper we prove symmetry results for solutions of semilinear elliptic equations in a ball or in an annulus in R N , N ≥ 2, in the case where the nonlinearity has a convex ﬁrst derivative. More precisely we prove that solutions having Morse index j ≤ N are foliated Schwarz symmetric, i
LQAC-4: Fourth release of the Large Quasar Astrometric Catalogue

Context. From an astrometric point of view, quasars constitute the best and almost ideal reference objects in the celestial sphere, with a priori no significant proper motion. Since the third release of the Large Quasar Astrometric Catalogue (LQAC-3), a large number of quasars have been discovered, in particular those coming from the DR12Q release of the SDSS. Moreover, for cross-matched objects, we have taken advantage of the very accurate determinations of the quasars identified within the recent Gaia DR1 catalogue. Aims. Following the same procedure as in the three previous releases of the LQAC, our aim is to compile the large majority of all the quasars recorded so far. Our goal is to record their best coordinates and substantial information concerning their physical properties such as the redshift as well as multi-bands apparent and absolute magnitudes. Emphasis is given to the results of the cross-matches with the Gaia DR1 catalogue. Methods. New quasars coming from the DR12Q release were cross-matched with the precedent LQAC-3 compilation with a 1′′ search radius, in order to add the objects without counterpart to the LQAC-4 compilation. A similar cross-match was done with Gaia DR1 to identify the known quasars detected by Gaia. This enables one to improve significantly the positioning of these objects, and in parallel to study the astrometric performance of the individual catalogues of the LQAC-4 compilation. Finally, a new method was used to determine absolute magnitudes. Results. Our final catalogue, called LQAC-4, contains 443 725 objects. This is roughly 37.82% more than the number of objects recorded in the LQAC-3. Among them, 249 071 were found in common with the Gaia DR1, with a 1′′ search radius. That corresponds to 56.13% of the whole population in the compilation. Conclusions. The LQAC-4 delivers to the astronomical community a nearly complete catalogue of spectroscopically confirmed quasars (including a small proportion of compact AGNs), with the aim of giving their best equatorial coordinates with respect to the ICRF2 and with exhaustive additional information. For more than 50% of the sample, these coordinates come from the very recent Gaia DR1.
Statistical Method-Based Multi-Model Ensemble Forecasting for North American Hazardous Air Quality

Wildﬁres can cause hazardous air quality conditions and aﬀect human health. Accurate prediction of wildﬁre air quality is challenging due to uncertainties in ﬁre emission, plume rise, etc. Ensemble forecasting techniques have been increasingly used to improve the predictability of wildﬁre aerosols. In this study, we aim to explore several ensemble creation methods to improve the ensemble forecast compared to the traditional ensemble mean. Our results show that the ensemble mean outperforms individual models in predicting ﬁne particles (PM2.5) when compared to AirNow observations. To further improve the ensemble forecast, we employ various statistical methods, including multiple linear regression, ridge regression, weighted regression, and quantile regression to develop weighted ensembles. These weighted ensembles are capable of reducing model systematic error, e
Tropical Paciﬁc Inﬂuence on the Source and Transport of Marine Aerosols to West Antarctica*

The climate of West Antarctica is strongly inﬂuenced by remote forcing from the tropical Paciﬁc. For example, recent surface warming over West Antarctica reﬂects atmospheric circulation changes over the Amundsen Sea, driven by an atmospheric Rossby wave response to tropical sea surface temperature (SST) anomalies. Here, it is demonstrated that tropical Paciﬁc SST anomalies also inﬂuence the source and transport of marine-derived aerosols to the West Antarctic Ice Sheet. Using records from four ﬁrn cores collected along the Amundsen coast of West Antarctica, the relationship between sea ice–modulated chemical species and large-scale atmospheric variability in the tropical Paciﬁc from 1979 to 2010 is investigated. Signiﬁcant correlations are found between marine biogenic aerosols and sea salts, and SST and sea level pressure in the tropical Paciﬁc. In particular, La Ni ~ na–like conditions generate an atmospheric Rossby wave response that inﬂuences
Placebo and Nocebo Effects Are Defined by Opposite Opioid and Dopaminergic Responses

Context : Placebo and nocebo effects, the therapeutic and adverse effects, respectively, of inert substances or sham procedures, represent serious confounds in the evaluation of therapeutic interventions. They are also an example of cognitive processes, particularly expectations, capable of influencing physiology. Objective : To examine the contribution of 2 different neurotransmitters, the endogenous opioid and the dopaminergic (DA) systems, to the development of placebo and nocebo effects.
A PDA Intervention to Sustain Smoking Cessation in Clients With A PDA Intervention to Sustain Smoking Cessation in Clients With Socioeconomic Vulnerability Socioeconomic Vulnerability

This manuscript describes a pilot study to examine feasibility of a personal digital assistant (PDA) in clients in the hospital setting with social economic status vulnerability (SES) and tobacco addiction. The purpose of this research program is to make a positive impact on the health and quality of life of the target population by assisting them to make a permanent change and sustain smoking cessation after discharge through use of an innovative smoking cessation program called the Follow-up Relationship Intended to END Smoking Personal Digital Assistant (FRIENDS PDA). The aims are to explore: 1) Acceptance of the technology based intervention by evaluating utilization, perception of use, ease of use, satisfaction and technical difficulties, 2) Feasibility of the study by examining the attrition rate and methods for recruitment and retention; and 3) Data collection methods for treatment protocols and the reliability of instruments for primary (smoking cessation verified by biomarker of saliva cotinine) and secondary (depression, weight, and self-efficacy temptation situations) outcomes for a future larger study. The sample was 31 medical surgical clients with a mean age of 47.35 (± 13.3), an average education of grade 11, average income of $13,629 and average household between 2 and 3 people. They were enrolled in a hospital smoking cessation program and invited to participate in a relapse prevention program (FRIENDS PDA) after discharge. The results showed after 2 months there was high utilization of the PDA. The participants viewed the PDA as useful and easy to use, had high satisfaction and would recommend use to other smokers. Numerous technical problems were identified and indicated areas for future improvements. The feasibility of the study methods was demonstrated. There were 73 potential participants referred over six months with 31 meeting the inclusion criteria who were entered into the study. The attrition rate was 21% at 2 months. A power analysis showed 192 clients would be needed for a fully powered study which would require additional data collection sites. The data collection time was 1 hour or less. Cronbach Alphas for the instruments ranged from . 72 to.96. The FRIENDS PDA treatment protocol was successfully implemented in all 31 participants. There was a continuous abstinent rate of 33% (n=10) at two months. A future study is warranted in a larger sample
Theoretical study of some statistical procedures applied to complex data

The main part of this thesis aims at studying the theoretical and algorithmic aspects of three distinct statistical procedures. The first problem is the binary matrix completion. We propose an estimator based on a variational approximation of a pseudo-Bayesian estimator. We use a different loss function of the ones used in the literature. We are able to compute non asymptotic risk bounds. It is much faster to compute the estimator than a MCMC method and we show on examples that it is efficient in practice. In a second part we study the theoretical properties of the regularized empirical risk minimizer for Lipschitz loss functions. We are therefore able to apply it on the logistic regression with the SLOPE regularization and on the matrix completion as well. The third chapter develops an Expectation-Propagation approximation when the likelihood is not explicit. We then use an ABC approximation in a second stage. This procedure may be applied to many models and is more precise and faster than the classic ABC approximation. It is used in a spatial extremes model.
INEQUALITY BEYOND GDP: A LONG VIEW

This paper addresses international inequality in multidimensional well-being during the last one-and-a-half centuries. Inequality fell in health and education since the late 1920s, due to the globalization of mass schooling and the diffusion of the health transition, but only dropped in population-weighted terms from 1970 onward for political and civil liberties, as the emergence of authoritarian regimes increased its dispersion since the end of World War I. In terms of augmented human development inequality declined since 1900. These results are at odds with per capita income inequality that rose over time and only shrank from 1990 onward. The gap between the OECD and the Rest of the world accounted only partially for inequality in well-being since the dispersion within developing regions became its main driver from the mid-20th century onward. Countries in the middle and lower deciles of the world distribution achieved the largest relative gain over the past century.
Domain-specific Evaluation of Word Embeddings for Philosophical Text using Direct Intrinsic Evaluation

We perform a direct intrinsic evaluation of word embeddings trained on the works of a single philosopher. Six models are compared to human judgements elicited using two tasks: a synonym detection task and a coherence task. We apply a method that elicits judgements based on explicit knowledge from experts, as the linguistic intuition of non-expert participants might differ from that of the philosopher. We find that an in-domain SVD model has the best 1-nearest neighbours for target terms, while transfer learning-based Nonce2Vec performs better for low frequency target terms.
Multislice Computed Tomography Scan Assessment of Accuracy and Safety of Free-Hand Pedicle Screw Fixation in Adolescent Idiopathic Scoliosis

Background data: Various methods to help guidance of screw purchase in adolescent idiopathic scoliosis (AIS) have been described in the literature. Free-hand technique is a relatively easy and is as accurate as other methods. Multislice computed tomography (MSCT) scan, the most accurate method of postoperative evaluation of screw purchase, still needs more research. Purpose: The aim of this study was to evaluate the accuracy and safety of the pedicle screw ﬁ xation (PSF) with free-hand technique in AIS using postoperative MSCT scan. Study design: A prospective clinical case study was performed. Patients and methods: In this prospectively study, all patients with AIS underwent correction using the free-hand PSF were reported. All patients underwent whole spine radiograph and MSCT scan during the follow-up. Screw purchases were evaluated according to the Gertzbein e Robbins classi ﬁ cation. Results: A total of 45 patients were recruited for this study with a mean age of 14.7 ± 1.7 years, including 39 females and six males. Of the total 870 pedicle screws, 85.1% (740) of screws were accurate within the pedicle, whereas 14.9% (130) of screws penetrated the pedicle, including medial wall penetration in 5.9% and lateral penetration in 9.0%. Overall, 18.3% of thoracic screws penetrated the pedicle, whereas 5.9% of lumbar screws penetrated the pedicle. Correlation of screw purchase accuracy to age, sex, curve type, Cobb angle, and spinal region showed no statistically signi ﬁ cant correlation. Conclusions: The data of this prospective study suggest that PSF with free-hand technique in AIS population appears to be an accurate and safe procedure (2022ESJ263).
Delta neutrophil index in obese and non-obese polycystic ovary syndrome patients

Objective We aimed to evaluate the usefulness of delta neutrophil index (DNI), a new inflammatory marker, in polycystic ovary syndrome (PCOS). Methods This retrospective case-control study was conducted at a tertiary health center. The DNI and other blood parameters obtained from the complete blood count examination of 227 individuals, consisting of 72 PCOS patients and 155 controls, were compared between the two groups. A receiver operating characteristic analysis was performed to examine the relationship between DNI and PCOS. Results DNI, white blood cell (WBC) count, and neutrophil count were significantly higher in the PCOS group than in the control group (P=0.028, 0.011, and 0.037; respectively). DNI and WBC counts were significantly higher in nonobese-PCOS patients (P=0.018 and 0.041; respectively). When the obese-PCOS and obese-control groups were compared, only neutrophil count was significantly higher in obese-PCOS patients (P=0.016). Significance was observed at cut-off values of 0.015 (area under the curve [AUC]=0.588) (P=0.034; sensitivity, 78%; specificity, 35%; Youden’s index=0.133) for DNI: 9.35 (AUC=0.594) (P=0.022) for WBC; and 5.38 (AUC=0.628) (P=0.002) for neutrophils. Conclusion Higher DNI in PCOS patients and similar results in the non-obese-PCOS group were observed when obese and non-obese-PCOS patients were considered separately. However, the lack of difference in the obese-PCOS group strengthens the hypothesis that there is obesity-independent inflammation in PCOS.
Coronavirus Pandemic Evaluation of Remdesivir to the outcomes of hospitalized patients with COVID-19 infection in a tertiary-care hospital in southern India

Introduction: Remdesivir was the only antiviral used in the treatment of COVID-19 in the first wave of the COVID-19 pandemic, following the adaptive COVID-19 treatment trial-1 interim analysis report. However, its use in moderate to critical hospitalized COVID-19 patients continues to be controversial. Methodology: In a cohort of 1,531 moderate to critical COVID-19 patients, we retrospectively performed a nested case-control study where 515 patients on Remdesivir were compared to 411 patients with no Remdesivir. Cases and controls were matched for age, sex and severity. The primary outcome was in-hospital mortality and secondary outcomes were duration of hospital stay, need for intensive care unit (ICU), progression to oxygen therapy, progression to non-invasive ventilation, progression to mechanical ventilation, and duration of ventilation. Results: Mean age of the cohort was 57.05 + 13.5 years. 75.92% were males. Overall, in-hospital mortality was 22.46% (n = 208). There was no statistically significant difference in all-cause mortality among cases and controls (20.78% vs. 24.57%, p = 0.17). Progression to non-invasive ventilation was lower in the Remdesivir group (13.6% vs 23.7%, p < 0.001), however progression to mechanical ventilation was higher in the Remdesivir group (11.3% vs 2.7%, p value < 0.001*). In a subgroup analysis of critically ill patients, the use of Remdesivir lowered mortality (OR 0.32 95% CI: 0.13 - 0.75). Conclusions: Remdesivir did not decrease the in-hospital mortality in moderate to severe COVID-19 but decreased progression to non-invasive ventilation. Its mortality benefit in critically ill patients needs further evaluation. Remdesivir may be useful if given early in the treatment of patients with moderate COVID-19.
Word final prolongations: acoustic characteristics and influence on speech fluency perception

ABSTRACT The aim of this study was to characterize word final prolongations in individuals with and without stuttering as well as to investigate the influence of end of words prolongations on speech fluency perception. In Experiment 1, 14 subjects were submitted to speech fluency evaluation for analysis of duration and average frequency of extended phones at the end of words. In Experiment 2, twenty lay judges were asked to judge the fluency degree of utterances without disfluency, utterances containing prolongations and utterances containing filled pauses. In experiment 1 the groups differed only in the duration’s variation; in both groups the prolongations in monosyllabic words prevailed; 80% of the prolonged phones in both groups were vowels. In experiment 2 no significant difference was found in the comparison between the judgements of prolongations and filled pauses. The utterances without disfluency differentiated themselves significantly from the others. We suggest that characteristics such as position in the word, duration and physical concomitants should be considered before deeming prolongations as a stuttering-like disfluency.
The impact of the resident duty hour regulations on surgical The impact of the resident duty hour regulations on surgical patients’ perceptions of care patients’ perceptions of care

Implementation of the 2003 Accreditation Council for Graduate Medical Education (ACGME) resident duty regulations and access to publicly reported patient satisfaction measures have challenged administrators and clinicians to balance resident’s educational experience, patient care quality, and patients’ satisfaction and perceptions. A pre retrospective study design investigated association between implementation of ACGME regulations and patient satisfaction/perceptions using multinomial logistic – June 2005), who responded to surveys at an academic medical center. Patients gave lower ratings for physician interactions (patient-physician interaction time, clinical updates, a hour regulations. While the odds of patients rating related to time spent, kept informed, and friendliness/ courtesy) were higher rating “ very good ”, the overall rating of quality care improved post increased interaction of patients with other hospital personnel. To improve patient satisfacti perceptions, initiatives such as workload balancing, hand for care providers are recommended. Finally, residency programs and institutions need to develop strategies for implementation of current and future ACGME duty hour regulations so as to balance patient safety, patient percep and resident well-being.
Integrative Pediatrics and Child Care Perinatal Anxiety, Microbiome Alterations, and Implications for Research in the Development of Autism and Schizophrenia

Autism Spectrum Disorder (ASD) and Schizophrenia have appeared similar in recent years with respect to genetic consistencies, phenotypic overlap, and overall neurodevelopmental course. Both disorders present with heterogeneous groups of positive and negative symptoms in the context of varying cognitive and adaptive clusters. Not surprisingly, both disorders have similar maternal correlates such as anxiety and stress, which have been linked to microbiome alterations in both mother and child. This commentary provides a brief overview of this overlap with respect to maternal microbiome alterations seen in these disorders and its implications for future research. Issues surrounding equity and social differences are also addressed. Implication for future research and clinical implications from these formulated hypotheses are discussed
