DETERMINATION OF THE MASS OF IGR J17091–3624 FROM “SPECTRO-TEMPORAL” VARIATIONS DURING THE ONSET PHASE OF THE 2011 OUTBURST

The 2011 outburst of the black hole candidate IGR J17091–3624 followed the canonical track of state transitions along with the evolution of quasi-periodic oscillation (QPO) frequencies before it began exhibiting various variability classes similar to GRS 1915+105. We use this canonical evolution of spectral and temporal properties to determine the mass of IGR J17091–3624, using three different methods: photon index (Γ)–QPO frequency (ν) correlation, QPO frequency (ν)–time (day) evolution, and broadband spectral modeling based on two-component advective flow (TCAF). We provide a combined mass estimate for the source using a naive Bayes based joint likelihood approach. This gives a probable mass range of 11.8 M ⊙ − 13.7 M ⊙ ? > . Considering each individual estimate and taking the lowermost and uppermost bounds among all three methods, we get a mass range of 8.7 M ⊙ – 15.6 M ⊙ ? > with 90% confidence. We discuss the possible implications of our findings in the context of two-component accretion flow.
Joint azimuth and elevation localization estimates in 3D synthetic aperture radar scenarios

The location of point scatterers in Synthetic Aperture Radar (SAR) data is exploited in several modern analyzes including persistent scatter tracking, terrain deformation, and object identification. The changes in scatterers over time (pulse-to-pulse including vibration and movement, or pass-to-pass including direct follow on, time of day, and season), can be used to draw more information about the data collection. Multiple pass and multiple antenna SAR scenarios have extended these analyzes to location in three dimensions. Either multiple passes at different elevation angles may be . own or an antenna array with an elevation baseline performs a single pass. Parametric spectral estimation in each dimension allows sub-pixel localization of point scatterers in some cases additionally exploiting the multiple samples in each cross dimension. The accuracy of parametric estimation is increased when several azimuth passes or elevations (snapshots) are summed to mitigate measurement noise. Inherent range curvature across the aperture however limits the accuracy in the range dimension to that attained from a single pulse. Unlike the stationary case where radar returns may be averaged the movement necessary to create the synthetic aperture is only approximately (to pixel level accuracy) removed to form SAR images. In parametric estimation increased accuracy is attained when two dimensions are used to jointly estimate locations. This paper involves jointly estimating azimuth and elevation to attain increased accuracy 3D location estimates. In this way the full 2D array of azimuth and elevation samples is used to obtain the maximum possible accuracy. In addition the independent dimension collection geometry requires choosing which dimension azimuth or elevation attains the highest accuracy while joint estimation increases accuracy in both dimensions. When maximum parametric estimation accuracy in azimuth is selected the standard interferometric SAR scenario results. When maximum estimation accuracy in elevation is selected the multiple baseline interferometric SAR scenario results. Use of a 2D parametric estimation method attains the best accuracy possible in both dimensions. When in some scenarios particularly the orbital case where the azimuth dimension is only approximately linear the full accuracy increase of linear joint azimuth and elevation is not fully attained. Images and point cloud estimates are shown for several linear and orbital SAR scenarios. Images provide a visual representation of the data while the quantitative point cloud data is a direct input for the multiple analyzes listed earlier.

ANGULAR DEPENDENCE OF METAMAGNETIC TRANSITIONS IN DYAGSB2

Measurements of the magnetization of DyAgSb{sub 2} reveal a complex system of up to 11 well-defined metamagnetic states for the field applied within the basal plane. Measurements of the magnetization vs the angle the applied field makes with respect to the [110] axis show the Dy{sup 3+} moments are constrained to lie along one of the four [110] directions within the basal plane. From the angular dependence of the critical fields and plateau magnetizations, the net distribution of the moments may be deduced for each state. Finally, the coupling constants are calculated within the framework of the {open_quotes}four-position clock model. {close_quotes} {copyright} {ital 1999} {ital The American Physical Society}
Y-STR Haplotypic Polymorphisms for the Hakka Population in West China and Phylogenic Comparison with Other Chinese Populations

The Hakka, who have undergone a series of great migrations, are usually identified with people who speak the Hakka language or share at least same Hakka ancestry. As the largest Hakka dialect island in West China, the Dongshan region was closely linked with the great migration wave of Hakka. However, the paternal genetic profiles of Dongshan Hakka have never been revealed. In the present study, 41 Y-chromosomal short tandem repeat (Y-STR) loci included in the SureID PathFinder Plus Kit were analyzed in 353 unrelated male individuals (171 Hakka and 182 Han) of Sichuan Province, China. By analyzing 166 different haplotypes among Dongshan Hakka and 176 different haplotypes among Sichuan Han males, haplotype diversity was calculated as 0.9997, with a discrimination capacity of 0.9708, for the Hakka population, and 0.9996 and 0.9670 for the Sichuan Han population, respectively. Most of the Y-STR loci were highly informative in both populations except DYS645. The genetic relationships were evaluated by comparing the Hakka population with 11 other groups that are relevant to Hakka migration routes. The results of the multidimensional scaling plot and phylogenetic tree indicate that the Dongshan Hakka population was closely related to Han nationalities from Anhui, Jiangxi, and Fujian Provinces.
ASCA Observations of the Distant Cluster A1204

We report the results of ASCA and Ryle Telescope observations of the distant cluster of galaxies A1204. The X-ray image shows that this source is very compact and that the intracluster gas is strongly centrally concentrated. The brightness temperature decrement of the cosmic microwave background radiation toward this cluster (the Sunyaev-Zeldovich effect) was not detected by the Ryle Telescope, with a 1 σ upper limit of |ΔT| < 360 μK. The gas temperature is 3.6 keV, which is considerably lower than that expected from the bright X-ray luminosity in the ROSAT band and explains the lack of detection. The hot gas mass within 1 Mpc is estimated to be ≲7 × 1013 M☉. In the wide window of the ASCA Gas Imaging Spectrometer, a very faint X-ray source was found at R.A. = 11h12m16s, decl. = +17°56'40'' (J2000). The observed count rate was too small to identify the X-ray emission mechanism in the new source.
Effect of Capital Inflows on Financial Development: The Case of Bangladesh

This study examines the effect of capital inflow components' on Bangladesh's financial development. The analysis applied the Autoregressive Distributive Lag (ARDL) model to reveal short-run and long-run associations by utilizing monthly data from January 2011 to December 2021. The study appoints two proxy variables: bank credit to GDP and bank deposit to GDP to address financial development. Findings of the analysis demonstrated that FDI and remittance inflow don't exhibit a significant relationship with financial development in the long run. However, foreign aid established a nexus with the financial progress of Bangladesh. The study recommends enacting policies to keep capital inflows under Bangladesh's financial system by repatriating foreign investors' profits and lessening remittance costs by facilitating and modernizing remittance management.
Functional Echocardiography (FNECHO); Experience in NICU of A Tertiary Care Hospital

Objective: To describe the observational findings of functional echocardiography (FnEcho) in neonatal intensive care unit of a tertiary care hospital by evaluating its frequency of use, characteristics of patients and distribution of heart diseases. Methodology: This Prospective descriptive observational study was done in a tertiary neonatal intensive care unit (NICU) in Rawalpindi, from July 2017 to June 2018. A total of two hundred and twelve neonates admitted to the NICU undergoing echocardiographic assessment were included in the study. Qualitative variables like gender, mode of delivery, and diagnostic findings were represented in terms of frequency and percentages. Quantitative data like age, birth weight and gestational age were highlighted as mean and standard deviation. Results: Out of a total of 212 neonates, 111 (52.4%) were male. The mode of delivery was noted to be lower segment cesarean section among 126 (60.0%) neonates. The mean gestational age was found to be 36.47+2.3 weeks, ranging from 28 to 41 weeks, whereas the mean birth weight was 2.56+0.68 kg, ranging from 1.1 to 4.2 kg. A total of 75 neonates were found to have functional heart disease in the form of pulmonary hypertension 37 (17.4%), hemodynamically significant patent ductus arteriosus 24(11.3%), hypoxic ischemic cardiomyopathy 4(1.9%), and systemic hypotension 10 (17.4%). Conclusion: FnEcho was found to be an effective tool for identifying different kinds of functional and structural heart defects. VSD was found to be the most common type of congenital heart disease, followed by PDA. Timely intervention in PPHN was also rewarding with good outcome.
A Thousand Plateaus

Scientists theorise that we now exist in theAnthropocene—an era when humanity hassuch an influence on the earth that the geologicaland ecological repercussions will be detectableindefinitely into the future. Microplastics,nuclear waste, industrial carbon, and otheranthropogenic waste products have createda new stratum that envelops the surfaceof the earth. Anthropogenic interference innatural systems has offset the stability of ourbiosphere. Ecological destabilisation is omnipresentwith anthropogenic climate change,among other symptoms, threatening to bringabout a Sixth Mass Extinction. The planetaryscale of the Anthropocene confronts humanitywith a unique challenge — designing for thefuture at a temporal scale appropriate for ageological epoch, not the egocentric time scaleof a human. The planetary scale impact of theAnthropocene infers a planetary responsibilitythat falls upon humanity — and the speculativearchitect. This thesis proposes the exploration of a speculativearchitectural future world that acknowledgesthe ever-transforming conditions of theAnthropocene. The speculative architecturaloutcomes represent a shift away from anthropocentricthinking, acknowledging the ubiquitouspresence of non-humans in the builtenvironment through architectural artefactsthat are self-determined participants of anever-expanding system — reclaiming non-humaninfluence over the flow of anthropogenicwaste. This design-led thesis’s allegorical investigationuses Gilles Deleuze and Felix Guattari’s AThousand Plateaus as a literary provocateur. Deleuze and Guattari advocate for design asa primary tool to achieve their vision of a ‘newearth’. The principal aim of this architecturaldesign investigation is to examine how computationalsimulation processes and iterativeexperimentation can propagate architecturalartefacts that invoke a shift in thinking awayfrom anthropocentrism. The principal researchobjectives are to investigate how philosophical,ecological, and systematic approaches can bereconfigured into an integrated framework toachieve this aim. As a Philosophical Approach, the artefactsengender Deleuze and Guattari’s concept of‘rhizomatic’ thinking, where systems representnomadic growth with no clear beginning or end. As an Ecological Approach, the artefactsaddress ecological imbalance by constructingthemselves out of the very anthropogenicwaste products that threaten the stability ofour biosphere. As a Systematic Approach, the artefacts representparts of a much wider, planetary scalesystem that systematically transforms inresponse to continually changing conditions.
A review of essential oils and their properties in the genus Campomanesia (Myrtaceae) from the Brazilian Cerrado

O gênero Campomanesia (Myrtaceae) compreende espécies de interesse econômico e científico. Produzem óleos essenciais (OE), extraídos a partir das folhas, frutos, sementes, raízes e casca. Das espécies de Campomanesia, 14 são encontradas no bioma Cerrado, um dos maiores domínios fitogeográficos brasileiros e é hotspot de biodiversidade e espécies endêmicas. O objetivo foi compreender os OE do gênero Campomanesia do Cerrado brasileiro, revisar as espécies e os constituintes bioativos desses óleos. Foram utilizadas as bases de dados Scopus, Web of Science, PubMed, Directory of Open Access Journal, Science Direct, com as palavras-chave: “essential oil” and “Campomanesia” combinada com o nome das espécies do Cerrado. Nas 37 publicações resultantes, há uma variedade de OE potenciais descritos, a maioria dos quais com atividades antimicrobiana e antioxidante. C. adamantium e C. pubescens foram as mais citadas e cinco espécies no gênero não foram incluídas pelos critérios de pesquisa. Compostos com potencial atividade biológica incluem os monoterpenos como os principais constituintes dos óleos voláteis dos frutos, enquanto os sesquiterpenos são compostos majoritários nas partes restantes das plantas. Assim, os OE da Campomanesia fornecem alternativas potencialmente interessantes e viáveis para alimentação e terapêutica. O uso sustentável da biodiversidade, aliado à biotecnologia, é o caminho para desenvolver produtos mais naturais ou compostos que se combinem sinergicamente com produtos sintéticos, reduzindo as concentrações necessárias para atingir o efeito desejado. Assim, com as muitas espécies de Campomanesia no Cerrado, a conservação da biodiversidade pode ser aliada ao uso sustentável e proporcionar benefícios, da mesa à farmácia, em futuro próximo.
Analysts’ stock ratings and the predictive value of news and Twitter sentiment

ABSTRACT This study investigates the relationship between the stock ratings of professional analysts and company-level sentiment. I find that investor sentiment expressed in tweets and news articles displays a positive relationship with professional analysts’ stock ratings and that the sentiment conveyed through tweets has a stronger effect than the sentiment from conventional news articles. Furthermore, the effect of sentiment derived from tweets and news articles on analysts’ ratings is stronger when the sentiment valence is the same (negative or positive) and weaker when the sentiment valence differs. The findings shed light on the link between investor sentiment and analysts’ stock ratings by demonstrating that analysts’ stock ratings are influenced by investor sentiment.
Conformally quasi-recurrent pseudo-Riemannian manifolds

Conformally quasi-recurrent pseudo-Riemannian manifolds are investigated, with emphasis on 4-dimensional Lorentzian ones. It is shown that the Ricci tensor and the gradient of the fundamental vector are both Weyl compatible tensors (the notion was introduced recently by the authors); topological conditions for the vanishing of the first Pontryagin form are stated. The fundamental vector of conformally quasi-recurrent 4-dimensional Lorentzian manifolds is null and unique up to a scaling; moreover it is an eigenvector of the Ricci tensor and its integral curves are geodesics. Such Lorentzian manifolds are Petrov type-N with respect to the fundamental null vector.
Cognitive Diagnostic Assessment of IELTS Listening: Providing Feedback from its Internal Structure

High stakes testing, such as IELTS, is designed to select individuals for decision-making purposes (Fulcher, 2013b). Hence, there is a slow-growing stream of research investigating the subskills of IELTS listening and, in feedback terms, its effects on individuals and educational programs. Here, cognitive diagnostic assessment (CDA) performs it through breaking down the abstract listening concepts into fine-grained subcomponents, and applying it to in-class assessment and teaching. Therefore, the strengths and weaknesses of language learners concerning various subsections of the IELTS listening test were explored with use of three CDMs, i.e., DINA, DINO and mixed DINA-DINO. As a result, the analysis of the participants’(N=463) performances revealed that the mixed-DINA-DINO model using the original Q-matrix was the most effective model. On the other hand, all three models indicated that gap-filling was cognitively less demanding than the other subsections. However, they did not show any agreement on multiple-choice sub-competency. Accordingly, it can be argued that the CDM-driven diagnostic information related to the sub-sections of the IELTS listening test can be used in educational systems to explore the underlying structure of a test and detect the learners’ potential strengths and weaknesses with mastery and non-mastery of the intended items.
The nexus between political globalisation, higher education, health development and ecological innovation in China: evidence from a nonlinear approach

The perspective of ecological innovation is widely studied around the globe because of its future demand in building a stable economy. Thus, the vital concept of the present study is to investigate the nexus between political globalisation and ecological innovation; while examining the impact of higher education (H.E.) and health development in China via the Quantile autoregressive distributed lagged (Q.A.R.D.L.) method. According to Cho et al. (2015), the Quantile Autoregressive lagged method is superior to the lasted estimation software because of its uniqueness of quantile base. However, through the analysis explanation of the ecological innovation concerning political globalisation, H.E. and health development are checked in long-run and short-run quantiles. The Q.A. R.D. L. technique investigations revealed that error correction parameters are negatively significant across all the quantiles. Hence this confirmed the presence of reversion to the long-standing association between ecological innovation and political globalisation, H.E. and health development. This implies that the affirmative impact of political globalisation (P.G.L.O.B.), H.E. , H.D. L. and gross domestic product (G.D.P.) on ecological innovations emerges positive change in the environment of China. However, the Granger causality test describes the bi-directional relationship amongst the selected variables. Some potential implications for the China country are discussed in the last paragraphs of the study.
Compactly Generated Triangulated Categories and the Telescope Conjecture

The thesis studies the telescope conjecture for algebraic compactly generated triangulated categories. The conjecture, which says that every smashing localization of a compactly generated triangulated category is generated by compact objects, is answered in affirmative in several cases. Main techniques to achieve this include homological algebra and basic set theoretic methods. At the end, a characterization for homotopy categories of complexes being compactly or, more generally, well generated is given for a wide class of additive categories.
Animal models for the study of acute cutaneous wound healing

The process of wound healing is critical to maintaining homeostasis after injury. Although a considerable amount has been learned about this complex process, much remains unknown. Whereas, studies with human volunteers are ideal given the unique nature of the human skin anatomy and immune system, the lack of such clinical access has made animal models prime candidates for use in preclinical studies. This review aims to discuss the strengths and limitations of the commonly used mammalian species in wound healing studies: murine, rabbit and porcine. Thereafter, a survey of models of various acute wounds such as cutaneous, ear, and implant are presented and representative studies that use them are described. This review is intended to acquaint readers with the vast spectrum of models available, each of which has a distinct utility. At the same time, it highlights the importance of utilising clinical samples to complement investigations conducted in animal models. Through this strategy, it is hoped that forthcoming research may be more reflective of the acute wound healing process as it occurs in humans.
Fine-grained Location Extraction via Curriculum Learning

Named Entity Recognition (NER) seeks to ex-001 tract entity mentions from texts with predefined 002 categories such as Person , Location . General 003 domain NER datasets like CoNLL-2003 mostly 004 annotate Location coarse-grained entities (e.g., 005 a country or a city). However, many appli-006 cations require to identify fine-grained loca-007 tions from texts and map them precisely to 008 geographic sites (e.g., a crossroad or a store). 009 Therefore, we propose a new NER dataset Har-010 veyNER with fine-grained locations annotated 011 in tweets. This dataset presents unique chal-012 lenges and characterizes many complex and 013 long location mentions in informal descriptions. 014 Considering Curriculum Learning can help a 015 system better learn the hard samples, we adopt 016 it and first design two heuristic curricula based 017 on the characteristic difficulties of HarveyNER, 018 and then propose a novel curriculum that takes 019 the commonness of sample difficulty into con-020 sideration. Our curricula are simple yet ef-021 fective and experimental results show that our 022 methods can improve both the hard case and 023 overall performance in HarveyNER over strong 024 baselines without extra cost. 025
