Authors: González-Rodríguez Alexandre , Seeman Mary V. , Natividad Mentxu , Barrio Pablo , Román Eloïsa , Balagué Ariadna , Paolini Jennipher Paola , Monreal José Antonio
Published: February 2023

Women with schizophrenia require health interventions that differ, in many ways, from those of men. The aim of this paper is to review male and female care needs and describe a newly established care unit for the treatment of women with schizophrenia. After reviewing the literature on the differentiated needs of men and women with schizophrenia, we describe the new unit’s assessment, intervention, and evaluation measures. The program consists of (1) individual/group patient/family therapy, (2) therapeutic drug monitoring and adherence checks, (3) perinatal mental health, (4) medical liaison, (5) suicide prevention/intervention, (6) social services with special focus on parenting, domestic abuse, and sexual exploitation, (7) home-based services, (8) peer support, (9) occupational therapies (physical activity and leisure programs), and (10) psychoeducation for both patients and families. Still in the planning stage are quality evaluation of diagnostic assessment, personalized care, drug optimization, health screening (reproductive health, metabolic syndrome, cardiovascular health, cancer, menopausal status), and patient and family satisfaction with services provided. Woman-specific care represents an important resource that promises to deliver state-of-the-art treatment to women and, ideally, prevent mental illness in their offspring.

Published: February 2023

The policy orientations of advanced neoliberal democracies situate young people as rational actors who are responsible for their own career outcomes. While career scholars have been critical of how this routinely ignores the unequal effects of structural constraints on personal agency, they have long suggested that young people should have access to the best available ‘roadmaps’ and advice to navigate the uncertainties baked into the contemporary economic landscape. Complementing the significant attention that is given to the (potentially emancipatory) experience of formal careers guidance, we present findings from a multi-method study. We explore young Australians’ (aged 15–24) navigation of careers information through a nationally representative survey (n = 1103), focus groups with 90 participants and an analysis of 15,227 social media comments. We suggest that the variety of formal and informal sources pursued and accessed by young people forms a relational ‘ecology’. This relationality is twofold. First, information is often sequential, and engagements with one source can inform the experience or pursuit of another. Second, navigation of the ecology is marked by a high level of intersubjectivity through interpersonal support networks including peers, family and formal service provision. These insights trouble a widespread, but perhaps simplistic, reading of young people having largely internalised a neoliberal sensibility of ‘entrepreneurial selfhood’ in their active pursuit of a range of career advice. Throughout our analysis, we attend to the ways that engagement in the career information ecology is shaped by social inequalities, further underscoring challenges facing careers guidance and social justice goals.
Weighted quadrature formulas for semi-infinite range integrals
Authors: Milovanović Gradimir V.
Published: February 2023

Weighted quadrature formulas on the half line \((a,+\infty)\), \(a>0\), for non-exponentially decreasing integrands are developed. Such \(n\)-point quadrature rules are exact for all functions of the form \(x\mapsto x^{-2}P(x^{-1})\), where \(P\) is an arbitrary algebraic polynomial of degree at most \(2n-1\). In particular, quadrature formulas with respect to the weight function \(x\mapsto w(x)=x^\beta\log^m x\) (\(0\le \beta<1\), \(m\in \mathbb{N}_0\)) are considered and several numerical examples are included.

A generalization of the Lupaș \(q\)-analogue of the Bernstein operator
Authors: Finta Zoltan
Published: February 2023

We introduce a Stancu type generalization of the Lupaș \(q\)-analogue of the Bernstein operator via the parameter \(\alpha\). The construction of our operator is based on the generalization of Gauss identity involving \(q\)-integers. We establish the convergence of our sequence of operators in the strong operator topology to the identity, estimating the rate of convergence by using the second order modulus of smoothness. For \(\alpha\) and \(q\) fixed, we study the limit operator of our sequence of operators taking into account the relationship between two consecutive terms of the constructed sequence of operators.

Authors: Argyros Ioannis K. , Khattri Sanjay K.
Published: February 2023

We expand the applicability of the midpoint method for approximating a locally unique solution of nonlinear equations in a Banach space setting. Our majorizing sequences are finer than the known results in scientific literature [1,3,4,5,6,7,8,9,10,11,19,20,21,23] and the convergence criteria can be weaker. Finally, numerical work is reported that compares favorably to the existing approaches in the literature [6, 8-16, 24-26,28].

Website is an information technology that can be used to exchange information between users quickly by using the internet network. The website has been used by various institutions as a medium of information and promotion. One of them is school. Currently, SMKN 1 Jonggat does not have a website that is used as a medium of information and promotion. This causes problems for both the community and the school. People to get the information they need from schools, they have to come to school. The school also does not have a media that can be used to provide information and school promotion. Therefore, the service team held service activities that aimed to assist the school in creating a website that can be used as a medium of information and promotion. This activity is divided into three stages, namely planning, implementation and evaluation. The result of the planning stage is cooperation related to activities and data collection needed in making the website. At the implementation stage, the service team created a school website according to the results of the planning stage. The evaluation stage is the inspection stage related to the school website that has been created. The service team succeeded in creating a school website according to the needs of the school that can be used as a medium of information and promotion. With the school website, the problems of SMKN 1 Jonggat related to the distribution and delivery of information and promotions can be minimized
Dwory kobiece w historiografii hiszpańskiej
Authors: Urjasz-Raczko Matylda
Published: February 2023

Badania poświęcone dworom kobiecym w okresie nowożytnym w Hiszpanii cieszą się dużym zainteresowaniem naukowców. Swoisty zwrot w historiografii tego przedmiotu dokonał się, gdy wykazano, że kobiety w dawnych czasach odgrywały dużo większą rolę społeczną, niż przypuszczano. Odejście od stereotypu kobiety nowożytnej w badaniach pozwoliło dostrzec jej rolę społeczną (oprócz rodzinnej) w nieformalnym układach, zwłaszcza w konstrukcji sieci klientalnych. W związku z tym niezależnie od tego, czy badania dotyczyły kultury, polityki, czy sztuki, oś badań dworów kobiecych w Hiszpanii stanowią indywidualne powiązania klientalne. Badacze dworów hiszpańskich są głównym środowiskiem, które podejmuje w swych pracach tematykę roli kobiet jako graczy polityczno-społecznych w dawnej monarchii hiszpańskiej.
Wilno – Kraków – Wilno
Authors: Januszek-Sieradzka Agnieszka
Published: February 2023

W artykule poruszono kwestię podróży królowej Barbary Radziwiłłówny (1523–1551, koronowana 7 XII 1550), drugiej żony króla Zygmunta II Augusta (1520–1572, panował od 1548 r.). W polskiej historiografii zagadnienie podróży królowych podejmowane było incydentalnie, a do rzadkości należą ujęcia, które widzą podróż nie tylko jako przemierzanie przestrzeni i przekraczanie granic geograficznych i politycznych, ale w wymiarze symbolicznym. Podróże podejmowane przez Radziwiłłównę uznać należy z jednej strony za odbiegające od europejskiego i polskiego standardu ze względu na nierówność stanową małżonków i powszechną niechęć do królowej oraz z uwagi na silne uczucie, które żywił do niej Zygmunt August, a także krótki okres, jaki spędziła u jego boku. Z drugiej strony, mimo tych charakterystycznych okoliczności, swoją warstwą symboliczną jak najbardziej wpisują się w europejską tradycję i obyczaj. Najważniejszą i wymagającą przekroczenia największej liczby rzeczywistych i symbolicznych granic, bogatą w rytuały przejścia (rites de passage), była podróż „ślubna” do ojczyzny męża. Ta podróż z Wilna do Krakowa, mimo że odbyła ją nie narzeczona, ale żona, i mimo że była rozciągnięta w czasie i wymagała dodatkowych, długich postojów Barbary w drodze (Radom, Nowe Miasto Korczyn), zawiera zwyczajowe etapy podróży ślubnej, znaczone szeregiem rytuałów przejścia. W czasie pobytu w Krakowie Barbara przedsiębrała wraz z mężem liczne podróże do nieodległych Niepołomic, które stanowiły wyraźną ucieczkę przed trudnościami i rygorami życia na Wawelu. Z jednej strony królewska para, inaczej niż większość koronowanych głów, mogła spędzać czas niemal prywatny. Z drugiej, pobyty w Niepołomicach potęgowały trudności adaptacyjne Radziwiłłówny, a króla narażały na zarzut zaniedbywania obowiązków. Charakter pośmiertnego triumfu Zygmunt August nadał ostatniej podróży żony z Krakowa do Wilna, gdzie – zgodnie z własnym życzeniem – spoczęła po śmierci.

Published: February 2023

W niniejszym artykule dwór królowej postrzegany jest jako miejsce jej aktywności, gdzie tworzy ona wielowymiarowe relacje międzyludzkie, stając się centrum skomplikowanej społecznej sieci. Jego celem jest przedstawienie habsburskich żon Zygmunta III jako świadomych pań dworu, mających wpływ na dobór dworzan. Królowe Anna i Konstancja inicjowały proces rekrutacyjny. Korzystały z pośrednictwa dworu monachijskiego. Miały sprecyzowane wymagania odnośnie do kandydatów na dworzan. Oceniały pracę swoich sług. W zamian otaczały ich troskliwą opieką. Habsburżanki dbały o odpowiednie warunki bytowe i finansowe swoich dworzan, a zwłaszcza wychowanie i korzystne zamążpójście dworek. Swoimi działaniami sprawiały, że ich dwory przypominały solidnie zarządzane gospodarstwa.
E-administracja - doświadczenia samorządu regionalnego w budowie systemu informatycznego - studium przypadku
Authors: Guz Hubert
Published: February 2023

Autor postawił pytanie: jakie warunki wewnętrzne i zewnętrzne muszą zaistnieć, aby administracja publiczna mogła samodzielnie budować i eksploatować systemy informatyczne? Dokonano przeglądu literatury teoretycznej, następnie wykorzystano studium przypadku (wywiady, obserwacja, przegląd dokumentów), poddając analizie proces budowy i eksploatacji systemu e-RPO przez Urząd Marszałkowski Województwa Małopolskiego (UMWM). Na podstawie analizy SWOT/TOWS zdefiniowano kluczowe mocne i słabe strony oraz szanse i zagrożenia. Ustalono, że UMWM wzmacniał swoje mocne strony (m.in. eliminacja papieru, szybka komunikacja, wpływ na system, ułatwienie pracy), aby wykorzystać szanse (m.in. możliwości techniczne, możliwość uczenia się). Analiza podkreśla pozytywne znaczenie oddolnego podejścia do e-administracji przez organizację publiczną i jej członków, jednocześnie wskazując ryzyka tego procesu.

Published: February 2023

In this work, the effects of He ion and electron beam irradiation on substrate-type CdTe solar cells that are suitable for the detection of alpha and beta radiation are investigated. He ion irradiation revealed that the induced current proportionally increased with the increase of He ion current and that it is possible to detect alpha radiation using a substrate-type CdTe solar cell dosimeter. Next, the electron irradiation effects were investigated. The induced current proportional to the electron flux was also observed, and the sensitivity depended on the electron energy. In addition, the degradation of a substrate-type CdTe solar cell dosimeter by electron beam irradiation was investigated. No significant degradation in short-circuit current was observed at the electron irradiation of 3 × 1016 cm−2 at 200 keV and 1 × 1016 cm−2 at 400 keV. This result suggests that the substrate-type CdTe solar cell dosimeter is sufficiently resistant to electron irradiation.
Characterization of undoped and N–Ti codoped Zn5Sb3Te chalcogenides
Authors: Fujiwara Takao , Niiyama Koji , Yin You
Published: February 2023

In this study, undoped Zn5Sb3Te (ZST) and N–Ti codoped ZST chalcogenides were investigated. The deposition rate of chalcogenides decreased when N and Ti were doped into ZST, caused by the low speed of reaction to form nitrides and the strong bond of Ti atoms, respectively. Surface roughness was significantly reduced to approximately one-seventh of the original value owing to the doping of N–Ti into ZST, implying high reliability. Based on X-ray diffraction and electrical measurements, the crystallization of ZST occurred after it was annealed at a high temperature between 250 °C and 300 °C, while codoping N–Ti into ZST further increased the crystallization temperature to above 300 °C. The crystallization temperature of N–Ti codoped ZST was approximately 150 °C higher than that of the conventional Ge2Sb2Te5 chalcogenide, indicating high thermal stability.
Corrosion Risk Estimation and Cause Analysis on Turbofan Engine
Authors: Lacaille Jérôme , Langhendries Raphaël
Published: February 2023

Turbofan engine parts are subject to corrosion. This degradation is only very difficult to observe outside of engine dismantling on predefined inspection dates. On the other hand, it is necessary to go specifically to observe the impacted parts to notice this wear. This inspection process is long, expensive and rarely carried out with the aim of detecting a corrosion effect. The provision of an indicator to alert on potential corrosion and to target parts is highly anticipated. Better still, if the origin of this corrosion can be identified by numerical methods, it will then be possible to improve the calculation of the lifespan of the part and to space out engine inspections.

We offer an indicator estimating if an engine part is corroded. In addition to the alert subject to this estimate, we also offer a graphical means to interpret this detection.
Dynamic delay-dispersive UWB-Radar Targets: Modeling and Estimation
Authors: Gedschold Jonas , Semper Sebastian , Thomä Reiner , Döbereiner Michael , Del Galdo Giovanni
Published: February 2023

This publication proposes a parametric data model and a gradient-based maximum likelihood estimator suitable for the description of delay-dispersive responses of multiple dynamic UWB-radar targets. The target responses are estimated jointly with the global target parameters range and velocity.

The large relative bandwidth of UWB has consequences for model-based parameter estimation. On the one hand, the Doppler effect leads to a dispersive response in the Doppler spectrum and to a coupling of the target parameters which both need to be considered during modeling and estimation. On the other hand, the shape of an extended target results in a dispersive response in range which can be resolved by the radar resolution. We consider this extended response as a parameter of interest, e.g., for the purpose of target recognition. Hence, we propose an efficient description and estimation of it by an FIR structure only imposing a restriction on the target's dispersiveness in range. 

We evaluate the approach on simulations, compare it to state of the art solutions and provide a validation on measurement data.

Multi-UAV IRS-assisted Communications: Multi-Node Channel Modeling and Fair Sum-Rate Optimization via Deep Reinforcement Learning
Authors: Iacovelli Giovanni , Coluccia Angelo , Grieco Luigi Alfredo
Published: February 2023

Unmanned Aerial Vehicles (UAVs) combined with Intelligent Reflective Surfaces (IRSs) represent a cutting-edge technology for improving the channel capacity of wireless communications, by capitalizing on UAVs' 3D mobility coupled with the IRSs' smart radio capabilities. This work envisions a scenario in which a swarm of UAVs equipped with IRSs serves multiple Internet of Things (IoT) Ground Nodes (GNs) concurrently transmitting to a single Base Station (BS) via OFDMA. The huge number of passive elements composing the IRSs introduces a significant complexity in the mission design. Therefore, each IRS is divided into patches that can be simultaneously used to serve different nodes. Considering general Rician fading, a comprehensive channel model for IRS-assisted UAV-aided networks is derived. Then, a multi-objective mixed-integer non-linear programming problem is conceived to maximize the sum-rate of the GNs and, at the same time, minimize the difference among the users' data rates, by jointly optimizing the trajectories and the phase shift matrices. This non-convex problem, reformulated in terms of scheduling (i.e., patch-GN assignment), is challenging to solve. Hence, it is rearranged as a Markov Decision Process and a quasi-optimal solution is obtained via Deep Reinforcement Learning. Extensive simulation analysis is performed to validate the results and the accuracy of the proposed model.
Retrieval of Subsurface Soil Moisture and Vegetation Water Content from Multi-frequency SoOp-Reflectometry: Sensitivity Analysis
Authors: Kim Seho , Garrison James , Kurum Mehmet
Published: February 2023

Signals of opportunity reflectometry (SoOp-R), the re-utilization of non-cooperative satellite transmissions for communication and navigation, is a promising approach to remote sensing of root-zone soil moisture (RZSM). Satellite transmissions in the frequency ranges of 137-138, 240-270, and 360-380 MHz are of interest due to the increased penetration depth. These can be combined with Global Navigation Satellite System Reflectometry (GNSS-R) in L-band (1575.42 MHz) to estimate the subsurface SM profile. The objective is to define requirements (e.g. frequency and polarization combinations, observation error, and temporal coincidence of multi-source observations) for satellite-based remote sensing of RZSM. Our approach is to use synthetic observations generated from multi-year time series of in-situ SM measurements from seven United States Climate Reference Network (USCRN) sites and dynamic vegetation structure based on a simple scaling method. A multi-frequency/polarimetric retrieval algorithm is developed and applied to these synthetic observations and used to predict retrieval errors for a range of changes in system parameters. We found that the use of both high and low frequencies improves retrieval accuracy by limiting uncertainties from vegetation and surface SM and providing sensitivity to deeper layers. Moreover, the retrieval errors were found to increase linearly with the reflectivity error and inter-frequency time delays. A bivariate model derived from this linear relationship will be useful for developing requirements on reflectivity precision based upon science requirements for SM/VWC retrievals. Although orbits of specific transmitter constellations were used to generate realistic distributions of incidence angle combinations, the method and results could be applied more generally.

Published: February 2023

Acute myeloid leukemia has been classified on the basis of morphology, cytochemistry and genetic profile. IDH gene is an epigenetic modifier whose mutation is involved in pathogenesis of various malignancies. This study was planned to study the prevalence of IDH1/2 mutation in denovo AML cases at a tertiary care Centre in North India and also to study its clinicopathological effect in these cases. We evaluated 60 patients registered at our Centre for diagnosis and treatment of AML. Routine investigations, bone marrow examination, flow cytometry were done followed by PCR and sequencing. Out of the total 60 patients of AML 4(6.7%) patients had IDH1R312 mutation and 5(8.3%) Patients had IDH2R172 mutation. IDH2 R140 mutation was not detected in any sample. IDH mutation was significantly associated with high risk AML group. No significant clinicopathological correlation was seen. In this study significant association was observed between IDH mutation and high risk AML cases. There was no paediatric case with IDH mutation. IDH mutation and AML might have an age related association.

Published: February 2023

With the exponential increase in genomic data, analyzing and processing large datasets has become a challenging task in healthcare. To address this issue, the Global Alliance for Genomics and Health (GA4GH) has proposed a set of community standards for enabling the adoption of FAIR principles for data, software, and infrastructure. These standards promote the concept of sending analysis and processing workflows to the data rather than transferring large datasets, thereby increasing efficiency and data security. In this paper, we present the outcomes of the ELIXIR Biohackathon 2021 project, where we worked on our software WESkit, which implements the GA4GH WES standard for running Snakemake and Nextflow workflows. During the hackathon, we implemented basic GA4GH TRS support, deployed a cloud platform, and added S3 support for downloading result files.
Кey signs of ecosystem assets valuation
Authors: Kolmakova Valentyna M.
Published: February 2023

The purpose of the article is to develop scientific approaches and identify key features of the assessment of ecosystem assets of territorial communities.

The article examines modern scientific approaches to the assessment of ecosystem assets of territorial communities in the context of deepening processes of decentralization of management. The essence of the definition of ecosystem assets from the standpoint of ecosystem accounting is revealed, in particular, it is focused on one of their main characteristics: the ability of natural reserves (stocks) to provide a constant flow (flow) of ecosystem services. The necessity of taking into account the market value of ecosystem assets in the process of monitoring their use and involvement in economic circulation at the local level has been determined. In this sense, the role of ecosystem services in providing links between ecosystem assets and benefits is considered. The main characteristics of ecosystem assets are investigated, their common and distinctive features from natural resource and production assets of spatial territorial entities are revealed. A systematization of generalized approaches to the methodology for assessing ecosystem assets according to the recommendations of the TEEB (The Economics of Ecosystems and Biodiversity), which is advisable to apply for territorial communities as key strategic guidelines for sustainable spatial development, is proposed. It is recommended to include the indicator “ecosystem assets” (EA) as a mandatory component of annual national accounts.

Further research has prospects in the following areas:

formation of an integrated strategic approach to the implementation of ecosystem asset valuation at the local level;

development and implementation of effective methodological approaches to the assessment of ecosystem assets for the formation of investment attractiveness of the territory through the use of local natural resources as ecosystem assets for sustainable spatial development.
A REVIEW OF INTERNATIONAL TRADE AND BUSINESS DEVELOPMENT IN GHANA TOWARD FOREIGN TRADE
Authors: Taylor Eric Aidoo , Zhytkevych Olena
Published: February 2023

It has been established that economic globalization is an important area of research when it comes to doing business across borders and has impacted it in many ways. International trade, though largely an economic activity is governed by rules and regulations. For example, assistance giving through subsidies makes the exported products cheaper and more affordable and may provide additional incentives to produce same products by domestic enterprises.
The main goal of this work is to perceive implications of how the administration of policies on international market penetration by domestic producers in Ghana affects foreign trade and how to conduct business across borders, rules and regulations of the country. For this purpose, the paper identified how regulations of foreign trade can influence the way exporters and importers conduct business and the way to manage them.
The work has provided, first of all, a review of the foreign trade figures of Ghana, trade barriers and import prohibitions as a protectionism to protect domestic producers. Then review of established potential ways and opportunities of improving Ghana’s foreign direct investment in the framework of international trade has been conducted and justified.
The outcomes of proposed reviews helped the authors to clarify ways of improving and enhancing business development in the framework of foreign trade in Ghana. The methodological basis for this work were peer-reviews journal articles, acclaimed internet publications, personal data analysis and calculations.
Zoo Tourism in the Visegrad Four Countries
Authors: Nekolný Lukáš
Published: February 2023

Attendance is one of the indicators of tourist attractions' success. Zoological gardens are among the most visited tourist attractions. However, there is practically no research on this topic, less so in the post-socialist countries. It is the aim of this article, therefore, to identify, using the example of the Visegrad Four countries (Czechia, Hungary, Poland, and Slovakia), how zoo attendance generally develops and to discuss why it is so. For this purpose, a database of EAZA member zoos in these countries was created. Attendance data was obtained from multiple sources, e.g. from annual reports, the International Zoo Yearbook (IZY) and email communication. It was found that the total attendance has been on the rise since it plummeted at the beginning of the 1990s; Czech zoos went up first and now they are the absolutely most visited, even per capita. The current attendance (2019) to Czech zoos more than doubled compared to the mid-1960s; in Slovakia and Poland it does not reach even 150%. There was an increase of almost 43 % in 2010–2019; the highest one was in Poland. The most visited zoo since 2015 has been the Wrocław Zoo (PL), where an iconic Afrykarium was opened.

Halal tourism witnessed a significant growth during the second half of the decade ended on December 2020 with COVID19 pandemic. This expansion can be witnessed equally in academic research and Halal tourism industry. Keeping in view the phenomenal growth this research performs review of the very high quality research literature on Halal tourism to consolidate its findings and recommendations. It performs thematic analysis of 74 articles published between the period 2009 to 2020 i.e., up to before the beginning of the COVID19 pandemic, listed in the A* and A ranked journals of the Australian Business Deans Council (ABDC). It consolidates research methodologies, themes, dependent/independent and mediating/moderating variables, which ultimately lead to a master conceptual framework of research. It highlights that the research on Halal tourism is in its developing stages, with more themes emerging in the recent years. It suggests that every country must reflect the blend of its own culture duly enveloped in the Shariah parameters. Finally, this review of literature highlights a nexus between Social values, tourism services and Islamic stipulations, as a way forward for research and developments in the Halal tourism research and industry.

South Africa Education Data and Visualisations
Authors: Combrink Herkulaas
Published: February 2023

  

The tabular and visual dataset focuses on South African basic education and provides insights into the distribution of schools and basic population statistics across the country. This tabular and visual data are stratified across different quintiles for each provincial and district boundary. The quintile system is used by the South African government to classify schools based on their level of socio-economic disadvantage, with quintile 1 being the most disadvantaged and quintile 5 being the least disadvantaged. The data was joined by extracting information from the debarment of basic education with StatsSA population census data. Thereafter, all tabular data and geo located data were transformed to maps using GIS software and the Python integrated development environment. The dataset includes information on the number of schools and students in each quintile, as well as the population density in each area. The data is displayed through a combination of charts, maps and tables, allowing for easy analysis and interpretation of the information.

The extremely-low-mass white dwarfs (ELM WDs) and pre-ELM WDs are helium-core white dwarfs with mass <∼ 0.3M
⊙. Evolution simulations show that a lower mass limit for ELM WDs exists at ≈0.14M
⊙ and no ELM WD is proposed by observation to be less massive than that. Here we report the discovery of a binary system, LAMOST J224040.77-020732.8 (J2240 in short), which consists of a very low-mass hot star and a compact companion. Multiepoch spectroscopy shows an orbital period P
orb = 0.219658 ± 0.000002 days and a radial-velocity semiamplitude K1 = 318.5 ± 3.3 km s−1, which gives the mass function of 0.74M
⊙, indicating the companion is a compact star. The F-type low-resolution spectra illustrate no emission features, and the temperature (∼7400 K) is consistent with that from spectral energy distribution fitting and multicolor light-curve solution. The optical light curves, in ZTF g, r, and i bands and the Catalina V band, show ellipsoidal variability with amplitudes of ∼30%, suggesting that the visible component is heavily tidally distorted. Combining the distance from Gaia survey, the ZTF light curves are modeled with Wilson–Devinney code and the result shows that the mass of the visible component is

A Reinforcement Learning–Based Follow-up Framework

Published: February 2023

Classification and characterization of variable and transient phenomena are critical for astrophysics and cosmology. Given the volume of nightly data produced by ongoing and future surveys such as LSST, it is critical to develop automatic tools that assist in observation decision-making, maximizing scientific output without resource wastage. We propose a reinforcement learning–based recommendation system for real-time astronomical observation of sources. We assess whether it is worth making further observations and recommend the best instrument from a preexisting candidate set of instruments. Current possible choices include single-band, multiband, and spectroscopic observations, although it is generalizable to any other kind of instrumentation. We rely on a reward metric to make recommendations, which incorporates the gain in a classification sense and the cost incurred for the queried observations. This metric is flexible and easily adaptable to different application scenarios. We run 24 simulations in an offline setting with preexisting observations from Gaia DR2 and SDSS DR14. We propose four comparison strategies, including the baseline strategy, which recommends based on the most similar past cases to the current case. Our strategy surpasses all other strategies in regard to reward. We reach an accuracy of 0.932, comparable to using the accuracy reached using all possible resources (0.948) but with half the number of photometric observations and 1000 times fewer spectroscopic resources. The baseline strategy lacks the complexity to achieve competitive results with our proposed strategy. Our framework is meant to aid continuous online observation decision-making and can be extended to incorporate multiple environmental and observation conditions.

We present an atmospheric retrieval analysis of a pair of highly variable, ∼200 Myr old, early T type planetary-mass exoplanet analogs SIMP J01365662+0933473 and 2MASS J21392676+0220226 using the Brewster retrieval framework. Our analysis, which makes use of archival 1–15μm spectra, finds almost identical atmospheres for both objects. For both targets, we find that the data is best described by a patchy, high-altitude forsterite (Mg2SiO4) cloud above a deeper, optically thick iron (Fe) cloud. Our model constrains the cloud properties well, including the cloud locations and cloud particle sizes. We find that the patchy forsterite slab cloud inferred from our retrieval may be responsible for the spectral behavior of the observed variability. Our retrieved cloud structure is consistent with the atmospheric structure previously inferred from spectroscopic variability measurements, but clarifies this picture significantly. We find consistent C/O ratios for both objects, which supports their formation within the same molecular cloud in the Carina-Near moving group. Finally, we note some differences in the constrained abundances of H2O and CO, which may be caused by data quality and/or astrophysical processes such as auroral activity and their differing rotation rates. The results presented in this work provide a promising preview of the detail with which we will characterize extrasolar atmospheres with JWST, which will yield higher-quality spectra across a wider wavelength range.
