Machine-learning approach for mapping stable orbits around planets
Authors: Pinheiro Tiago F. L. L. , Sfair Rafael , Ramon Giovana 
Published: December 2024

Context. Numerical N-body simulations are typically employed to map stability regions around exoplanets. This provides insights into the potential presence of satellites and ring systems.
Aims. We used machine-learning (ML) techniques to generate predictive maps of stable regions surrounding a hypothetical planet. This approach can also be applied to planet-satellite systems, planetary ring systems, and other similar systems.
Methods. From a set of 105 numerical simulations, each incorporating nine orbital features for the planet and test particle, we created a comprehensive dataset of three-body problem outcomes (star-planet-test particle). Simulations were classified as stable or unstable based on the stability criterion that a particle must remain stable over a time span of 104 orbital periods of the planet. Various ML algorithms were compared and fine-tuned through hyperparameter optimization to identify the most effective predictive model. All tree-based algorithms demonstrated a comparable accuracy performance.
Results. The optimal model employs the extreme gradient boosting algorithm and achieved an accuracy of 98.48%, with 94% recall and precision for stable particles and 99% for unstable particles.
Conclusions. ML algorithms significantly reduce the computational time in three-body simulations. They are approximately 105 times faster than traditional numerical simulations. Based on the saved training models, predictions of entire stability maps are made in less than a second, while an equivalent numerical simulation can take up to a few days. Our ML model results will be accessible through a forthcoming public web interface, which will facilitate a broader scientific application.
Rate coefficients for rotational state-to-state transitions in H2O + H2 collisions as predicted by mixed quantum–classical theory
Authors: Joy Carolin , Bostan Dulat , Mandal Bikramaditya , Babikov Dmitri 
Published: December 2024

Aims. A new dataset of collisional rate coefficients for transitions between the rotational states of H2O collided with H2 background gas is developed. The goal is to expand over the other existing datasets in terms of the rotational states of water (200 states are included here) and the rotational states of hydrogen (10 states). All four symmetries of ortho- and para-water combined with ortho- and para-hydrogen are considered.
Methods. The mixed quantum–classical theory of inelastic scattering implemented in the code MQCT was employed. A detailed comparison with previous datasets was conducted to ensure that this approximate method was sufficiently accurate. Integration over collision energies, summation over the final states of H2, and averaging over the initial states of H2 was carried out to provide state-to-state, effective, and thermal rate coefficients in a broad range of temperatures.
Results. The rate coefficients for collisions with highly excited H2 molecules are presented for the first time. It is found that rate coefficients for rotational transitions in H2O molecules grow with the rotational excitation of H2 projectiles and exceed those of the ground state H2, roughly by a factor of two. These data enable a more accurate description of water molecules in high-temperature environments, where the hydrogen molecules of background gas are rotationally excited, and the H2O + H2 collision energy is high. The rate coefficients presented here are expected to be accurate up to the temperature of ~2000 K.
Testing the asteroseismic estimates of stellar radii with surface brightness-colour relations and Gaia DR3 parallaxes
Authors: Valle G. , Dell’Omodarme M. , Prada Moroni P. G. , Degl’Innocenti S. 
Published: December 2024

Context. A recent investigation highlighted peculiar trends between the radii derived from surface brightness-colour relations (SBCRs) combined with Gaia DR3 parallaxes with respect to asteroseismic scaling relation radii from K2 data.
Aims.Kepler data differ from K2 data in many aspects. We investigated on the robustness of the results based on Kepler data.
Methods. We cross-matched asteroseismic and astrometric data for over 12 000 red giant branch and red clump stars from the end-of-mission Kepler catalogue with the Gaia DR3 and TESS Input Catalogue v8.2 to obtain precise parallaxes, V- and K-band magnitudes, and E(B − V) colour excesses. Two well-tested SBCRs from the literature were adopted to estimate stellar radii.
Results. The analysis confirmed that SBCR and asteroseismic radii agree very well. The overall differences are only 1–2% depending on the adopted SBCR. The dispersion of 7% was about two-thirds of what was found for K2-based data. As a difference from the K2-based investigation, the ratio of SBCRs-to-asteroseismic radii did not depend on the metallicity [Fe/H]. Moreover, the intriguing decreasing trend with [α/Fe] of the radius ratio for massive stars that was observed in K2 data was absent in Kepler data. The SBCR radii are systematically higher than asteroseismic estimates by 5% for stars with masses below 1.0 M⊙.
Conclusions. The SBCRs have proven to be a highly effective tool for estimating radii with a precision comparable to that obtained from asteroseismology, but at a significantly lower observational cost. Moreover, the superior concordance of Kepler-derived radii with SBCR measurements and the absence of the discrepancies observed in the K2-derived radii suggest the existence of underlying systematic errors that impact specific mass and metallicity regimes within the K2 dataset.

AbstractDevelopment of a simple, optimized closure method for mucosal defects left by gastric endoscopic submucosal dissection (ESD) is warranted. Herein, we developed a novel and dedicated closure device called FLEXLOOP and aimed to assess feasibility and safety of the closure using FLEXLOOP following gastric ESD.This multicenter, prospective, observational study enrolled patients clinically diagnosed with gastric neoplasms < 30 mm in size. Following gastric ESD, closure of the mucosal defect was performed using a FLEXLOOP with standard clips. The primary outcome was the complete closure rate. The secondary outcomes were procedure time, number of clips, sustained closure rate on second-look endoscopy on postoperative days (PODs) 5 to 7, and rate of post-ESD bleeding.Overall, 35 patients were included in this study. The median specimen size was 32 mm. The mucosal defect was completely closed in 31 patients (89%; 95% confidence interval, 73%-99%) and incompletely closed in four patients (11%). Median closure time was 11 minutes and median number of clips was 10. Second-look endoscopy performed on PODs 5 to 7 demonstrated sustained, partially sustained, and unsustained closures in seven (20%), 22 (63%), and six patients (17%), respectively. Post-ESD bleeding and complications related to FLEXLOOP were not observed.Closure using FLEXLOOP is feasible and safe. Our technique using this new device can be an attractive option for more easily closing mucosal defects. However, further clinical research is warranted to confirm that this technique can prevent delayed complications.
Gastric Cancer: Molecular Characterization, Therapeutic Innovations, and Perspectives
Authors: da Costa Emily Tonin , de Azevedo Sergio Jobim , Jácome Alexandre A. 
Published: December 2024

Abstract
Introduction Gastric cancer is the fifth most common neoplasm and the fourth leading cause of cancer-related death in the world. The present review aims to offer to the oncologic community the molecular characterization of gastric cancer, the therapeutic innovations and the perspectives for the systemic therapy for gastric cancer.
Materials and Methods We searched for articles in the PubMed database using Medical Subject Headings (MeSH). The latest publications and proceedings of meetings were also reviewed.
Results The cornerstone of the systemic therapy for gastric cancer is the dual combination of fluoropyrimidines and platin-based chemotherapy. Nevertheless, it is recommended that gastric cancer patients are tested for human epidermal growth factor receptor 2 (HER2), high-frequency microsatellite instability (MSI-H), programmed cell death-ligand 1(PD-L1), and claudin 18.2 expression. If HER2-positive, trastuzumab plus pembrolizumab should be added to the doublet chemotherapy. Anti-programmed cell death-1 (anti-PD-1) therapy, such as nivolumab or pembrolizumab, should also be added to chemotherapy in MSI-H and in the PD-L1-positive patients. Patients who present overexpression of claudin 18.2 should be treated with the combination of zolbetuximab and oxaliplatin-based chemotherapy. Immunotherapy may also be considered in patients with high tumor mutational burden. Clinical trials evaluating fibroblast growth factor receptor 2 (FGFR2) inhibitors and the dual inhibition anti-PD-1 and anti-T-cell immunoreceptor with immunoglobulin and immunoreceptor tyrosine-based inhibitory motif domains (anti-TIGIT) are promising.
Conclusions The clinical applicability of precision medicine in gastric cancer has risen in the past few decades, leading to substantial improvements in the efficacy of the systemic therapy. Testing patients for biomarkers is paramount for the appropriate management of advanced disease. Ongoing clinical trials evaluating new therapeutic strategies are promising and offer optimism for the patients affected by this challenging disease.
Dismantling Development: Towards an Abolitionist Theory of Development
Authors: Raghavan Priya 
Published: December 2024

AbstractWhat might it mean to approach development from an epistemic and programmatic lens aimed at the displacement of the very conditions that necessitate and sustain the international development-industrial complex? This paper explores the productive possibilities inaugurated by taking an expressly abolitionist approach to development. In doing so, I build on but also extend beyond calls to decolonise development in acknowledgement of development’s inextricable imbrication with racial capitalism and neo-colonialism. I identify non-reformist reform, disepistemologies, practices of refusal and radical complicity, and the notion of the undercommons as particularly useful abolition tools with which to approach the project of dismantling development. The paper does not constitute a comprehensive or even concrete set of prescriptions in relation to abolishing development—instead, it seeds various intellectual and political possibilities by bringing together two rich traditions of critique and resisting, inviting those of us within the development-industrial complex to collectively imagine and enact an abolitionist approach to development.
Gas-modulated optoelectronic properties of monolayer MoS2 for photodetection applications
Authors: Prajapat Pukhraj , Vashishtha Pargam , Gupta Govind 
Published: December 2024

Defects in monolayer MoS2 (M-MoS2) can cause complex electronic states that significantly affect its optical and electrical properties. Understanding and describing the impact of these defects, especially the role of sulfur vacancy (Vs) in M-MoS2 when integrating them into practical technologies, is crucial. However, a significant challenge exists in precisely controlling Vs generation in M-MoS2. This article presents an in situ defect engineering procedure for M-MoS2, considering the influence of external stimuli. We investigated how Vs changes and its impact on the optoelectronic characteristics of M-MoS2 after it is directly exposed to various gas environments. A photodetector device was fabricated, which exhibited an outstanding responsivity of 1.02 × 104 A/W, a detectivity of 1.2 × 1012 Jones, and an ultralow noise equivalent power of 1.56 × 10−18 W Hz−1/2. When the device is exposed to a reducing gas (H2S) environment, the performance increases by 136%, and in an oxidizing gas environment (NO2), it decreases by 68% in terms of responsivity due to a change in the concentration of Vs. We studied the photoresponse characteristics of the device by using Vs as the key parameter. This research contributes to the field of defect engineering in M-MoS2, expanding our knowledge of gas–surface interactions and assisting in producing highly sensitive optoelectronic devices.

Published: December 2024

Background People living with HIV (PLHIV) have historically faced a range of challenges negotiating satisfying sex lives in the context of virus transmission risks and HIV-related stigma. We examine the experience of sexual satisfaction among PLHIV in an era of pre-exposure prophylaxis (PrEP) and undetectable=untransmissible (U=U)/treatment as prevention. Methods Data are derived from HIV Futures 9, a cross-sectional survey of PLHIV in Australia conducted between December 2018 and May 2019. Logistic regression was used to identify factors associated with sexual satisfaction, including awareness of/engagement with U=U and PrEP as well as experiences that denote HIV-related stigma. Results Over half (56.5%) of the total sample (n = 715) reported they were not satisfied with their sex lives. Those who avoided sex because of their HIV status (44.4%) were more likely to report sexual dissatisfaction, as were those who were aged 50 years or over and those with worse self-reported health. Participants who expressed a concern about their drug use were more likely to report sexual dissatisfaction when compared with those who expressed no such concern. Conclusions Concerns about HIV continue to be present in the lives of PLHIV and can interrupt or undermine intimate and sexual relationships. Although biomedical prevention technologies such as PrEP and antiretroviral therapy may alleviate anxiety relating to onward transmission of HIV, these findings indicate that concerns about HIV status, which may be related to experiences of stigma, are still adversely associated with enjoyment of sex for those living with HIV.
Higher identity resilience – self-efficacy is associated with sexual risk behaviours in gay men
Authors: Jaspal Rusi , Yenihayat Asrin 
Published: December 2024

Cross-sectional survey data from 226 heterosexual and 201 gay men in the UK and Germany, analysed using moderation analyses, showed a positive relationship between identity resilience – self-efficacy and engaging in condomless sex and drug use in sexualised settings in gay men only. It is proposed that higher self-efficacy may lead to increased feelings of invincibility in gay men, which in turn is associated with sexual risk-taking.
Scalar diversity in L2 French speakers
Authors: Destruel Emilie , Starr Glenn 
Published: December 2024

Abstract
While scalar inferences associated with some have featured in most of the past investigations
into L2 implicature derivation, this study examines acquisition of pragmatic inferences licensed by adjective pairs (e.g.,
<intelligent, brilliant>, <dirty, filthy>). Previous work has focused mainly on
direct scalar implicatures where an utterance containing a weak scalar term implicates the negation of the stronger. This work
extends the investigation to include focus on two additional inference types: indirect scalar implicatures, where not
brilliant conveys intelligent, and negative strengthening, a type of manner implicature where
not brilliant results in a rather dumb interpretation. Using an inference-judgment paradigm,
we test the interplay of these three inference types in adjectival scales for French speakers and L2 French learners and find that
response behavior is modulated by the availability of alternative meanings for each participant group. L2 learners demonstrated
familiarity with direct and indirect scalar implicature but lack awareness of negative strengthening. We interpret these results
by highlighting the role of processing complexity as well as pragmatic competence and proficiency. Overall, this study makes an
empirical contribution to the field of L2 acquisition and adds to building a more encompassing understanding of mechanisms that
are often assumed to be universal in language acquisition.
A task-based needs analysis of primary school-aged children with
migrant or refugee backgrounds in Austria
Authors: Trager Vera , Gilabert Roger 
Published: December 2024

Abstract
In this study, we report on a task-based needs analysis (TBNA)
for primary school-aged newcomers to Austria. 31% of Austria’s primary school
students learn German as L2 and thus a systematic analysis of their language
learning needs is crucial. Semi-structured interviews were conducted and a
survey was distributed. Results show 38 crucial target tasks for social and
academic integration and their respective rankings regarding perceived frequency
and the need for training. Triangulation of multiple sources and methods
facilitated the identification of target tasks in various life domains and the
development of detailed task descriptions along multiple task dimensions.
Collectively, the results provide a basis for task selection, task sequencing,
and the development of a meaningful syllabus for refugee/migrant populations at
the primary school level in Austria.

Abstract
This study examines the structural, electrical, optical, and mechanical effects of hydrostatic pressure on cubic I-II-halide perovskite RbSrI3. The exchange–correlation term of the Khon-Sham equation is expressed using PBE-GGA. For all calculations, QuantumESPRESSO is used. PBE-GGA and pseudopotentials have been employed for ion-valence interaction. Under hydrostatic pressure, the lattice parameter

This material depicts the transition from an indirect band gap at ambient pressure to a direct band gap that accelerates electron valence-to-conduction band transition. The band gap rises to 7 GPa, then falls to 1.49 eV at 50 GPa. The PDOS explains that the states that contribute to creating VBM and CBM changes in overlapping status and value which leads to such behavior of electronic nature. Optical properties show a stronger response at 50 GPa pressure, with

Authors: Chen Hong , Yan Feiya , Yang Jing , Yan Jianguo , Qin Tao , Zhang Jing 
Published: December 2024

Abstract
Aluminum alloy ingot surface defect detection technology is crucial to ensure that product quality meets standards. Existing inspection model inspection precision and speed are difficult to meet requirements of fast and accurate detection on production lines, to address this problem, a new real-time surface defect detection algorithm Al-YOLO on aluminum alloy ingot casting line was proposed. Firstly, K-Means++ was embedded into YOLOv5 to optimize the detection anchor frame for the aluminum alloy ingot scenario. Secondly, the structural reparameterization technique was used to design the main trunk to speed up the model inference speed. Then combined with the dynamic head framework known as DyHead, the attention mechanism was unified with the detector’s head, thereby enhancing the precision of small defect identification. Finally, the Focal function was introduced, and combined with EIoU to get the Focal-EIoU border regression loss function to address the uneven sample distribution. On the aluminum alloy ingot surface defects dataset, the mAP of Al-YOLO reaches 72.5%, and the FPS also reaches 57.1, which improves the mAP and FPS by 4.0% and 11.2, respectively, compared to the original model, and outperforms the current mainstream detection methods on the NEU-DET dataset. Experimental evidence Al-YOLO has better inspection precision and speed, which can better adapted to the requirements of fast and accurate detection in production lines.
A selective chaos-driven encryption technique for protecting medical images
Authors: Chen Yucheng , Huang Huiqing , Huang Kekun , Roohi Majid , Tang Chunming 
Published: December 2024

Abstract
Smart devices, embedded in daily life, have limited memory, power, and processing capabilities, making traditional cryptography impractical and driving the development of lightweight cryptography. Selective encryption of medical images has gained significant attention for its lightweight performance. Nevertheless, existing methods face security challenges, such cannot resist chosen-plaintext attacks, that limit their practical use. To overcome these challenges, this paper introduces a novel selective encryption scheme based on chaos theory. The approach identifies regions of interest in medical images using an adaptive statistical threshold based on pixel intensity values, forming a sub-image block for encryption. The scheme employs a permutation-diffusion structure, utilizing bit-level circular shifts and pixel shuffling to modify both pixel positions and values. A randomized encryption operation in the diffusion phase ensures security against chosen-plaintext attacks. The final encrypted image integrates the encrypted sub-blocks with unencrypted regions, achieving a balance between efficiency and security. The comprehensive evaluation corroborates that our solutions outperform the existing state-of-the-art schemes regarding security and performance. Therefore, our proposed scheme is a practical solution for lightweight medical image protection in resource-constrained applications.
