Abstract
Stars collect most of their mass during the protostellar stage, yet the accretion luminosity and stellar parameters, which are needed to compute the mass accretion rate, are poorly constrained for the youngest sources. The aim of this work is to fill this gap, computing the stellar properties and the accretion rates for a large sample of Class I protostars located in nearby (<500 pc) star-forming regions and analyzing their interplay. We used a self-consistent method to provide accretion and stellar parameters by modeling the spectral energy distribution and using veiling information from near-IR observations when possible. We calculated accretion and stellar properties for the first time for 50 young stars. We focused our analysis on the 39 confirmed protostars, finding that their mass accretion rate varies between ∼10−8 and ∼10−4
M
⊙ yr−1 in a stellar mass range between ∼0.1 and 3 M
⊙. We find systematically larger mass accretion rates for our Class I sample than for Class II objects. Although the mass accretion rate we found is high, it still suggests that either stars collect most of their mass before the Class I stage, or eruptive accretion is needed during the overall protostellar phase. Indeed, our results suggest that for a large number of protostars the disk can be unstable, which can result in accretion bursts and disk fragmentation in the past or in the future.

Published: February 2023

Abstract
The Mg ii
h and k lines are among the best diagnostic tools of the upper solar chromosphere. This region of the atmosphere is of particular interest, as it is the lowest region of the Sun’s atmosphere where the magnetic field is dominant in the energetics and dynamics, defining its structure. While highly successful in the photosphere and lower to mid-chromosphere, numerical models have produced synthetic Mg ii lines that do not match the observations well. We present a number of large-scale models with magnetic field topologies representative of the quiet Sun, ephemeral flux regions and plage, and also models where the numerical resolution is high and where we go beyond the MHD paradigm. The results of this study show models with a much improved correspondence with IRIS observations in terms of both intensities and widths, especially underscoring the importance of chromospheric mass loading and of capturing the magnetic field topology and evolution in simulations. This comes in addition to the importance of capturing the generation of small-scale velocity fields and including nonequilibrium ionization and ion−neutral interaction effects. However, it should be noted that difficulties in achieving a good correspondence remain, especially when considering the width of Mg ii
h and k lines in plage. Understanding and modeling all these effects and their relative importance is necessary in order to reproduce observed spectral features and in isolating the missing pieces necessary to fully comprehend Mg ii formation.
Exotic Compact Objects with Two Dark Matter Fluids
Authors: Cassing Marie , Brisebois Alexander , Azeem Muhammad , Schaffner-Bielich Jürgen 
Published: February 2023

Abstract
The generic properties of compact objects made of two different fluids of dark matter are studied in a scale-invariant approach. We investigate compact objects with a core–shell structure, where the two fluids are separated, and with mixed dark matter components, where both dark matter fluids are immersed within each other. The constellations considered are combinations of incompressible fluids, free and interacting Fermi gases, and equations of state with a vacuum term, i.e., self-bound dark matter. We find novel features in the mass–radius relations for combined dark matter compact objects, which distinguishes them from compact objects with a single dark matter fluid and compact stars made of ordinary baryonic matter, such as white dwarfs, neutron stars, and quark stars. The maximum compactness of certain combined dark matter stars can reach values up to the causality limit for compact stars but not beyond that limit if causality of the dark matter fluids is ensured.
Updated High-temperature Opacities for the Dartmouth Stellar Evolution Program and Their Effect on the Jao Gap Location

Abstract
The Jao Gap, a 17% decrease in stellar density at M

G
∼ 10 identified in both Gaia Data Release 2 and Early Data Release 3, presents a new method to probe the interior structure of stars near the fully convective transition mass. The Gap is believed to originate from convective-kissing instability wherein asymmetric production of 3He causes the core convective zone of a star to periodically expand and contract and consequently causes the star luminosities to vary. Modeling of the Gap has revealed a sensitivity in its magnitude to a population metallicity primarily through opacity. Thus far, models of the Jao Gap have relied on OPAL high-temperature radiative opacities. Here we present updated synthetic population models tracing the Gap location modeled with the Dartmouth stellar evolution code using the OPLIB high-temperature radiative opacities. Use of these updated opacities changes the predicted location of the Jao Gap by ∼0.05 mag as compared to models that use the OPAL opacities. This difference is likely too small to be detectable in empirical data.
The diversity of cultivable endophytic fungi of the sand coast plant Ipomoea pes-caprae in Taiwan
Authors: Yeh Yu-Hung , Kirschner Roland 
Published: February 2023

Ipomoea pes-caprae is a plant of sand coasts and it can tolerate stresses, such as high salinity, strong wind and sand movements and lack of nutrients. It plays an important role in coast protection and preventing erosion. Fungal endophytes show high biodiversity and have a strong influence on the survival of plants under different stress factors. Although this plant is important for sand coast ecosystems, little is known about the associated fungi. In this study, we isolated and identified endophytic fungi of Ipomoea pes-caprae, a dominant plant along the shore of Taiwan. The dataset contains 896 records, which correspond to 177 species. The geographical scope of the dataset covers the northern subtropical area of the main island of Taiwan, with its sand coasts in New Taipei, Taoyuan, Hsinchu and Taichung and two botanical gardens in Taipei and Taichung. The detailed original data of fungal diversity are rarely publicly shared under strictly formalised and, thus, reusable standards. As an example for such an approach, the complete occurrence dataset was made available in the Darwin Core Archive format via the Global Biodiversity Information Facility (GBIF) under Version 1.13, Taiwan Biodiversity Information Facility (TaiBIF) https://doi.org/10.15468/9h9rcg. In this first data paper on endophytic fungi, the scientific name and associated DNA sequence in the dataset were directly linked to other free online resource (Index Fungorum, GenBank), which shows the potential of GBIF for linking together different online data repositories.
We describe a dataset, in which the diversity of endophytic fungi of the sand coast plant Ipomoea pes-caprae in Taiwan was investigated.
Invisibiliser la torture par le droit. Une comparaison Espagne / États-Unis
Authors: Guibet Lafaye Caroline , Delori Mathias 
Published: February 2023

Comment les démocraties libérales peuvent-elles mettre en œuvre des politiques de torture, sachant que ces pratiques sont à la fois interdites par leur droit domestique et le droit international ? Nous répondons à cette question à partir d’une enquête sur deux cas : l’Espagne depuis la transition démocratique et les États-Unis au début des années 2000. La littérature sur le sujet souligne que les démocraties libérales qui ont recours à la torture développent un stratagème : elles la rendent invisible. Notre étude va dans le sens de cette thèse tout en soulignant un autre aspect. En Espagne comme aux États-Unis, les partisans de la torture se sont appuyés sur le droit pour créer des zones de non-droit.
A Prescription Audit Using the Who Core Drug Use Indicators in a Rural Health Training Center of Pondicherry
Authors: Mercy Mani , Antony Lourdu Jafrin 
Published: February 2023

Introduction:
Prescription auditing is an important tool to assess the appropriateness of drug dispensing in any health-care setup.

Aim:
The aim of this study is to evaluate the prescriptions as per the World Health Organization (WHO) core indicators.

Materials and Methods:
The study is an observational study undertaken in the outpatient department of the rural health training center. About 310 prescriptions were analyzed for their completeness as per the WHO guidelines.

Results:
The auditing showed the distribution of gender as 62.90% in the male category and 37.09% in the female category. The age distribution of the prescription falls across the ages from 1 to 60 years with 64.51% in the under-five categories, 54.83% in the adolescent category, 17.74% in the middle age group, and 38.70% in the geriatric age group. The prescription indicators such as name and age of the patient, hospital id, dose of the drug, and duration of treatment were completely recorded in the out patient (OP) slip. The parameters like were near to completion such as history (98%), examination (99%), and signature with the name of the doctor (96.12%). Generic names of the drugs are entered in 89.67%, investigations were ordered in 63.87%, and follow-up was advised only in 54.19% of the prescriptions. Handwriting in capitals was only in 56.77% and the registration number of the doctor was entered only in 46.77% of the prescriptions.

Conclusion:
This study showed some pitfalls in the areas of prescribing indicators which have to be sorted out through proper training of the medical officers and interns posted in the health centers.

Authors: John Sally , Gupta Pankaj Kumar , Sathe Harshal Shriram , Yadav Priyanka 
Published: February 2023

Background:
The assessment of disability is an integral part of the management of patients with schizophrenia. The Indian Disability Evaluation and Assessment Scale (IDEAS) is a government-recommended tool used for the assessment and certification of disability in mental illnesses. The literature on the psychometric properties such as reliability and validity of IDEAS for the assessment of disability in schizophrenia patients is relatively scant.

Materials and Methods:
This was a cross-sectional, observational, descriptive study done in a tertiary health care center catering the rural patients in central India. A hundred male and female treatment-seeking schizophrenia patients, who were in symptom remission, were purposively included in the study. Apart from sociodemographic profile and severity assessment, the disability levels of the patients were assessed using IDEAS as well as the World Health Organisation Disability Assessment Scale version 2.0 (WHODAS 2.0).

Results:
The mean age of the patients included in the study was 36.6 (±9.11) years. Among the four disability domains in the IDEAS, maximum disability was seen in the work domain, whereas self-care was the least affected domain. Males had a higher disability in work, whereas in the individuals belonging to joint families and rural backgrounds, self-care was significantly affected. Pearson correlation test implied that IDEAS showed good internal consistency (Cronbach's alpha = 0.892) and concurrent validity with the WHODAS 2.0 in the assessment of disability in the study participants.

Conclusion:
IDEAS is a reliable and valid instrument for the measurement of disability in severe mental illnesses such as schizophrenia.
Factors Affecting Health-Related Quality of Life among Patients with Colorectal Cancer using the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire-CR29
Authors: Dey Soumya , Basu Abhishek , Banerjee Suparna , Bandyopadhyay Rajat 
Published: February 2023

Introduction:
The deterioration of health caused by colorectal Cancer (CRC) and its treatment leads to physiological, functional, and social damage impairing a CRC patient’s health-related quality of life (HRQoL). The study was done to estimate the factors affecting the HR QoL among patients with CRC.

Methodology:
Fifty-four CRC patients who had completed the treatment with surgery/chemotherapy/radiotherapy in a peripheral Medical College between May 2021 and April 2022 were enrolled. The objective was to assess patient’s perceived global health status and QoL (GHS/QoL), functional outcomes, and symptoms measured by the European organization for research and treatment of cancer Quality of life questionnaire core (QLQ-C30) and the CRC-specific QLQ-CR29 and to determine the demographics, clinical, treatment factors and symptom scales of the QLQ-C30/QLQ-CR29 that are associated with of GHS/QoL in patients with CRC

Results:
The mean age was 46 years, 59% were male, 41% had other long-term medical conditions, an ostomy was present in 30% and 41% of respondents had multimodal CRC treatment with surgery, radiotherapy, and chemotherapy. The final analysis of stepwise multiple regression revealed that four variables namely physical functioning, sexual interest, body image, and fatigue remained significant independent predictors of overall HRQoL score in CRC survivors accounting for 67.4% of the variation in overall HRQoL. Physical functioning made the strongest contribution. Women, at the extremes of the age groups (≥60 years), with an ostomy, without a spouse/partner, and those with other medical conditions in addition reported poorer functioning, symptoms, or overall HRQoL.

Conclusions:
The current study identifies factors associated with overall HRQoL among CRC survivors. Functional capacity and CRC-related problems were most strongly associated with overall HRQoL among CRC survivors. Greater efforts to identify CRC-related symptoms and diminished physical functional capacity among CRC survivors are warranted in an attempt to improve their overall HRQoL.

Authors: Ali Aya S. , Helal Duaa S. , Mohamed Dareen A. , Sallam Fersan A. 
Published: February 2023

Background
Colorectal carcinoma is one of the leading causes of morbidity and mortality worldwide. Fibroblast-activation protein is expressed in cancer-associated fibroblasts and its expression is upregulated during the transformation of benign colorectal tissue into cancer. Proliferating-cell nuclear antigen expression was used as a marker of cell proliferation and is considered as a marker able to identify aggressive adenomas that may in turn become malignant.

Aim
To study the expression of fibroblast-activation protein and proliferating-cell nuclear antigen in neoplastic epithelial colonic lesions and their role in adenoma–carcinoma sequence.

Patients and methods
This retrospective study aimed to evaluate the expression of fibroblast-activation protein and proliferating-cell nuclear antigen in 80 cases of neoplastic epithelial colonic lesions.

Results
In malignant colorectal epithelial tumors, high fibroblast-activation protein expression was detected with an increase in histological grade, depth of invasion, vascular invasion, and lymph-node metastasis. No fibroblast-activation protein expression was detected in all benign cases. In included benign cases, there was a significant relation between proliferating-cell nuclear antigen labeling index and both histological type and grade of dysplasia. In the included malignant cases, there was a significant relation between proliferating-cell nuclear antigen labeling index with grade of tumor and the depth of invasion.

Conclusions
Both fibroblast-activation protein and proliferating-cell nuclear antigen labeling index suggested to have a role in early detection of malignant transformation and had a prognostic role in malignant cases.

Authors: Maamoun Toulan Esraa Farid , Shalaby Helmy Ahmed , Elsayed Darwish Mohammed , Amer Aymen Mohammed , Serag Shaima Mohammed 
Published: February 2023

Background
Velopharyngeal insufficiency (VPI) is an anatomical or structural defect that hinders sufficient velopharyngeal closure, as visualized on nasoendoscopy.

Aim
The aim of this work was to compare the result of sphincter pharygoplasty versus buccinator myomucosal flap in management of VPI cases with coronal pattern of closure in order to select the proper operation for managing these cases.

Patients and methods
This study included 20 patients in our institute with residual VPI after primary repair of cleft palate with age range between 3 and 12 years. Randomly, patients with coronal pattern of closure were categorized into two groups: (A) 10 patients underwent sphincteroplasty and (B) 10 patients underwent buccinator myomucosal flap. Preoperatively and 2 months after operation, every patient was evaluated by auditory perceptual assessment, flexible nasopharyngoscopy, and nasometry. The results were documented, tabulated, and statistically analyzed.

Results
There were statistically significant improvements of auditory perceptual assessment in obligatory speech disorders and intelligibility of speech, nasometeric evaluation in oral and nasal sentences in both groups. Additionally, there were significant improvements of nasoendoscopic evaluations in the degree of velar movement, presence or absence and size of persistent gap in both groups, and in the degree of lateral pharyngeal wall movements in group A.

Conclusion
Sphincterpharyngoplasty or buccinator myomucosal flap have satisfactory results in treatment of VPI patients with coronal pattern of closure with no statistically significant difference between both groups.
Optimization of the anisotropic Cheeger constant with respect to the anisotropy

Published: February 2023

AbstractGiven an open, bounded set
$\Omega $
in
$\mathbb {R}^N$
, we consider the minimization of the anisotropic Cheeger constant
$h_K(\Omega )$
with respect to the anisotropy K, under a volume constraint on the associated unit ball. In the planar case, under the assumption that K is a convex, centrally symmetric body, we prove the existence of a minimizer. Moreover, if
$\Omega $
is a ball, we show that the optimal anisotropy K is not a ball and that, among all regular polygons, the square provides the minimal value.
THE CONCEPT OF "MUNICIPAL MAN": MODIFICATION IN THE LIGHT OF MARTIME
Authors: Boyarskіі O.O. 
Published: February 2023

The article considers the practical aspects of the implementation of the concept of "municipal man" (homo municipalis) in the legislation on local self-government and in the practice of local self-government bodies of the country, as well as its modifications in light of martial law.
It turns out that the concept of "municipal man" (homo municipalis), and, both in peacetime and in martial law and the actual conduct of hostilities has great methodological and praxeological potential for building and developing territorial human communities and improving the use of local government in a democratic state governed by the rule of law. It is, on the one hand, a harbinger of the formation and improvement of legal personality of each resident member of the local community, and on the other – a fundamental task of local government, carried out by local governments on behalf and in the interests of the local community.
A systematic analysis of the relevant legislative array shows that the current modern military legislation of Ukraine is characterized not only by complete disregard for the goals and objectives of local self-government during martial law, but also by neutralizing or significantly reducing the powers of local governments – moreover, replacing the main entity exercise of such powers (they are transferred from local governments to territorial military administrations), which, in essence, disintegrates the concept of "municipal man" and its implementation in the practice of local governments.
It is stated that the realities of today, as well as the important organizational, regulatory and managerial role of local governments within the territorial community in martial law determine changes in the position of the legislator to restore proper legal personality of local governments in the context of returning some powers to elected local actors. self-government, which marks the recognition and return to the concept of "municipal man" and its application in lawmaking and lawmaking.
Censura e liberdade de expressão
Authors: Prodorutti Alves Ana Carolina , Da Silva Corralo Giovani 
Published: February 2023

A presente pesquisa estuda a liberdade de expressão no Brasil e a censura, com foco nas manifestações artísticas ocorridas nos últimos anos. Um dos cernes do Estado Democrático de Direito é a liberdade de expressão, a permitir que todas as pessoas tenham o direito de manifestar as suas opiniões livremente através de qualquer forma de expressão artística. É por essa razão que a repercussão social e jurídica da exposição Queermuseu e outras exibições ainda possuem importância e merecem a atenção do mundo jurídico, especialmente a compreensão dos limites à liberdade de expressão artística no direito brasileiro – problema atacado. Para tanto, estudam-se os direitos fundamentais e seus limites, bem como a liberdade de expressão artística como manifestação do pensamento, o que permite a compreensão da exposição Queermuseu e outras exibições e o papel que o Estado deve desempenhar. Utiliza-se o método hipotético-dedutivo, a confirmar, na conclusão, a hipótese que o Estado deve garantir, através da atuação de todos os poderes em todos os níveis da Federação, a liberdade de manifestação artística, o que somente pode ser mitigado diante da colisão com outros direitos fundamentais, o que não ocorreu nas exposições analisadas.
