Published: January 2025

Abstract
The plausibility of an unseen planet in the outer solar system, and the expected orbit and mass of such a planet, have long been a topic of inquiry and debate. We calculate the long-term orbital stability of distant trans-Neptunian objects (TNOs), which allows us to expand the sample of objects that would carry dynamical information about a hypothetical unseen planet in the solar system. Using this expanded sample, we find statistically significant clustering at the ∼3σ level for TNOs with semimajor axes > 170 au in the longitude of perihelion (ϖ), but not in inclination (i), argument of perihelion (ω), or longitude of node (Ω). Since a natural explanation for clustering in ϖ is an unseen planet, we run 300 N-body simulations with the giant planets, a disk of test particles representing Kuiper Belt objects, and an additional planet with varied initial conditions for its mass, semimajor axis, eccentricity, and inclination. Based on the distribution of test particles after 1–2 Gyr, we compute relative likelihoods given the actual distribution of ϖ as a function of semimajor axis for distant TNOs on stable orbits using a significantly larger sample than previous work. We find the best-fit unseen planet parameters to have mass m

Abstract
The L’Ralph instrument is a key component of NASA’s Lucy mission, intended to provide spectral image data of multiple Jupiter Trojans. The instrument operates from ∼0.35 to 4 μm using two focal plane assemblies: a 350–950 nm multispectral imager, Multi-spectral Visible Imaging Camera (MVIC), and a 0.97–4 μm imaging spectrometer, Linear Etalon Imaging Spectral Array (LEISA). Instrument calibration was established through ground testing before launch and has been monitored during cruise utilizing internal calibration sources and stellar targets. In-flight data have shown that the instrument thermal performance is exceeding expectations, allowing for early updates to LEISA radiometric and pointing calibrations. MVIC radiometric performance remains stable more than 3 yr since launch. The serendipitous identification of a new flyby target, (152830) Dinkinesh, allowed testing of instrument performance and interleaved LEISA and MVIC acquisitions on an asteroid target. Both MVIC and LEISA obtained data of Dinkinesh and its moon, Selam, demonstrating that they show good spectral agreement with an S- or Sq-type asteroid, along with evidence of a 3 μm absorption feature.
Regional Economic Development of the PRC through the Data of the World Economic Statistics
Authors: Ostrovskii Andrei V. 
Published: January 2025

The article analyzes the results of a forecast on the socio-economic development of Chinese regions made ten years ago in a collective monograph by the Institute of the Far East of the Russian Academy of Sciences. These results are compared with data from various countries in terms of gross domestic product (GDP) and GDP per capita. Based on statistical data from the National Bureau of Statistics (NBS) of China for 2022, it was determined that China’s GDP ranks first globally in terms of purchasing power parity (PPP) and second in terms of the dollar exchange rate. More than half of China’s GDP continues to be concentrated in the coastal regions, which host the main “growth poles” of the Chinese economy: the Beijing – Tianjin – Hebei region, the Yangtze River Delta (encompassing Shanghai, northern Zhejiang, and southern Jiangsu), and the Pearl River Delta (southern Guangdong, including the Shenzhen and Zhuhai free economic zones).
According to GDP figures at the dollar exchange rate, not only Guangdong but also Jiangsu has surpassed Russia. Overall, in terms of GDP, most of China’s coastal regions have reached the level of Eastern European countries and Portugal.
Over the past decade, the gap in gross regional product (GRP) between the coastal regions and the central and western regions has significantly decreased. Most of China’s provinces now achieve GRP levels of $4-8 trillion per year (or $615-1.230 billion), surpassing the GDP figures of most countries worldwide. However, the gap between the coastal regions and the northeastern provinces (Heilongjiang, Jilin, and Liaoning) has widened. The GRP per capita in these three northeastern provinces is now lower than in the six central provinces.
To stimulate economic development in the western and central regions, as well as in the Northeast of China, the One Belt, One Road initiative was launched in 2013. This initiative aims not only to enhance the foreign economic relations of these lagging territories but also to ensure their accelerated growth by fostering new “growth poles” within these regions. The establishment of such poles is expected to drive faster development in these areas, thereby narrowing the economic gap between them and the more advanced coastal regions.
« La vision d’un monde marquée par les pratiques locales » au prisme du roman policier – entre « villes » et « campagnes »
Authors: Fukunishi Daisuke 
Published: January 2025

Le roman policier et l’ethnographie partagent de nombreux communs : ils sont nés en même temps et ont fait évoluer leur centre d’intérêt de la « ville » vers la « campagne ». Les écrivains ont ainsi mis en place dans leurs œuvres un monde basé sur les pratiques locales. On y rencontre en outre le concept ethnographique de « marebito ». Les problèmes qui éclatent dans cet espace clos qu’est la campagne sont résolus par des entités (une divinité, un détective) venues de l’extérieur (l’au-delà, la ville). Ces réflexions ont d’abord été développées pour comprendre les traditions populaires avant d’être employées dans le roman policier. Cela explique pourquoi ce genre est apprécié des Japonais et pourquoi ces mondes de pratiques locales décrites dans ces œuvres jouent un rôle important pour comprendre la société contemporaine de ce pays.
Quand les vaincus (re)construisaient la paix : les prisonniers de guerre allemands dans la sortie de guerre franco-allemande après 1945
Authors: Théofilakis Fabien 
Published: January 2025

Plus d’un million d’Allemands ont été prisonniers de guerre en mains françaises, entre 1944 et 1948. Pourtant, leur rôle, après 1945, dans la construction de la paix entre des ennemis dits héréditaires n’a pas été justement étudié. Cette absence est d’autant plus surprenante que la captivité a constitué, à une échelle inédite, une expérience de rencontre avec l’autre. À partir de trois histoires considérant tour à tour le point de vue des prisonniers, des autorités françaises et des populations dans la Zone française d’occupation, l’article se propose d’interroger en quoi la captivité allemande en mains françaises a pu contribuer au processus de pacification post-1945 et, in fine, pourquoi le second après-guerre aurait réussi là où le premier a échoué, à savoir remplacer la guerre de trente ans par une paix de près de quatre-vingts ans.
Administrateurs et diplomates de terrain ?
Authors: Bardet Valentin 
Published: January 2025

Cet article s’intéresse à un groupe social central dans la sortie de guerre post-Seconde Guerre mondiale : le personnel du Gouvernement militaire de la Zone française. Plus précisément, nous mènerons, à partir de l’analyse de leurs dossiers personnels, une biographie de groupe de fonctionnaires de terrain, les délégués de cercle, en charge du contrôle de la plus petite unité administrative de la zone. Situés à l’interface entre population allemande et administration française, ils incarnent les ambiguïtés de la politique française d’occupation. Les marges de manœuvre dont ils disposent justifient qu’on prête attention à leur parcours, pour comprendre dans quelle mesure ils remobilisent en Allemagne des savoirs et des pratiques acquises pendant leur carrière, qu’il s’agisse de confrontations antérieures avec l’Allemagne, d’expériences métropolitaines ou coloniales. Ces délégués sont aux avant-postes du changement d’attitude à l’égard de l’Allemagne au tournant des années 1950 : leur rôle évolue alors le plus souvent du contrôle à une forme de diplomatie de proximité.
Verständigung ? Penser la réconciliation israélo-arabe à partir d’une position yekke (juive allemande) en Israël
Authors: Farges Patrick , Goldblum Sonia 
Published: January 2025

Tout comme le conflit franco-allemand, le partage de la Palestine est un processus s’inscrivant dans la longue durée, dense et controversé. Dans ce contexte difficile, l’art de faire la paix s’avère particulièrement complexe. Nous proposons de décaler le regard sur cette question en nous intéressant à la perspective juive allemande. En effet, les Juifs allemands (et plus généralement les Juifs d’Europe centrale) fuyant le nazisme et ayant trouvé refuge en Palestine mandataire dans les années 1930 portaient en eux l’expérience douloureuse du nationalisme exacerbé, de la discrimination antisémite, de la persécution et de la migration forcée. Si l’émigration juive allemande en Palestine mandataire a suscité un regain d’intérêt depuis plus de vingt ans, tous les aspects de celle-ci n’ont pas reçu la même attention et peu de recherches ont été menées afin d’inscrire cette migration dans son contexte proche-oriental. Or les Juifs allemands (ou yekkes) sont arrivés en Eretz Israël avec des représentations, des affiliations et des socialisations politiques héritées de la bourgeoisie juive libérale allemande. En Palestine mandataire et au sein de la jeune nation israélienne en état d’alerte et de conflit quasi-permanent, les yekkes ont été les porteurs d’une voix alternative dans la manière d’envisager les relations avec les populations arabes. On retrouve ainsi nombre de yekkes dans les organisations promouvant l’entente (Verständigung), la paix voire la réconciliation. Si les relations israélo-arabes au xxe siècle incarnent un conflit paraissant indépassable, nous souhaitons montrer que des acteurs ont, dans l’adversité, continûment essayé de cultiver un art (minoritaire) de faire la paix au Proche-Orient. Le présent article cherche à la fois à retracer les origines intellectuelles de ce discours sur la paix et l’entente et à donner un aperçu des configurations sociales ayant conduit à l’émergence d’un tel discours à partir de la toute fin des années 1920.
Herramientas discursivas e imaginación política en las músicas de los blocos afro de Salvador de Bahía
Authors: Fernández Cordero Carolina 
Published: January 2025

El presente trabajo indaga en la música de los blocos afro de Salvador de Bahía (Brasil) a partir del análisis de sus canciones desde un punto de vista sociohistórico. En ellas la palabra (junto a la melodía, la percusión y la danza) surge como una herramienta discursiva más en la imaginación política emancipatoria de la comunidad afrodescendiente. Centrada sobre todo en la producción del siglo xx (décadas de los 70 a los 90), la investigación profundiza en la problemática sociopolítica y los recursos narrativos que contribuyen a la configuración de una cultura popular comunitaria y la reescritura de una historia negra propia.
Different radiologic procedures to evaluate the success of Pleurodesis in patients with malignant pleural effusion
Authors: Sadek Mohamed S. , Essawy Tarek S. , Taha Elsayed A. , Elnaggar Marwa E. 
Published: January 2025

Background
To treat symptoms brought on by a large, recurring malignant pleural effusion, chemical pleurodesis is recommended. Before pleurodesis, a drain is left in the pleural space until the pleural fluid collection stops. As little as 50 ml of pleural fluid can be found using chest ultrasonography, which can also verify the pleural surfaces’ conjunction, a sign of successful pleurodesis.

Patients and methods
Thirty patients with malignant pleural effusion had intercostal tube insertion as part of this interventional trial. Before the sclerosing drug was injected, transthoracic ultrasonography was used to evaluate each case to see whether the sliding sign was present. A month later, a follow-up transthoracic ultrasound was performed to evaluate the sliding sign, which indicates whether the pleurodesis was successful or not.

Results
The mean age of participants was 60 ± 12 years, with slightly more males (53.3%, n=16) than females (46.7%, n=14). Two-thirds (66.7%) reported chest pain, while half of the patients (50%) had complained of cough. The majority (76.7%, n=23) presented with pleural nodules. Every participant (100%) demonstrated the presence of both effusion and collapse in the computed tomography images. Most of the cases (63.3%, n=19) were treated with bleomycin during pleurodesis. All patients (100%) demonstrated the presence of the sliding sign before pleurodesis with significant absence after the procedure (P<0.001). 24 out of the 30 (80%) patients experienced successful outcomes.

Conclusions
Because thoracic ultrasonography may identify the lack of pleural sliding, it can be used to evaluate the success of pleurodesis. Furthermore, the results of pleurodesis were further confirmed by computed tomography scans and chest radiography, which completed the assessment by indicating the presence or absence of effusion and collapse.
Transthoracic Ultrasound of Parasternal Intercostal Muscles and its relation with severity of Chronic Obstructive Pulmonary disease
Authors: Gomaa Nehad Emad El Din , Ahmed Entesar Sayed , Eltrawy Heba H. , Galal Heba Mohamed 
Published: January 2025

Background
Chest wall musculature changes may indicate combined systemic consequences of chronic obstructive pulmonary disease (COPD), which disrupts respiratory mechanics locally due to airflow restriction and hyperinflation. It is possible to assess the amount and make-up of muscles using transthoracic ultrasonography.

Aim
To study the correlation between parasternal intercostal muscle thickness, COPD severity and the reliability of parasternal intercostal muscle ultrasound.

Patients and methods
A prospective observational case–control study was conducted on 120 participants; 60 of them were stable COPD patients and 60 healthy controls. Full clinical history taking, spirometry, and transthoracic ultrasound of parasternal intercostal muscle thickness (mm) were carried out on all studied participants.

Results
Our study revealed significantly lower mean values in the stable COPD group as regards RT second, third parasternal intercostal muscle thickness (mm) compared to controls and a significant positive correlation between forced expiratory volume in first second % and RT second, third parasternal intercostal muscles thickness (mm). The receiver operating characteristics curve reported that RT second and RT third parasternal intercostal muscle thickness cut-off value less than 5.7, with accuracy of 82.5and 79.2%, respectively, were found.

Conclusion
A decrease in parasternal intercostal muscle thickness was observed in stable COPD patients. Parasternal intercostal muscle thickness could be a predictor for COPD severity. Transthoracic ultrasound could be reliable in the assessment of the parasternal intercostal muscle.

Authors: Amer Ahmed M. , Kamel Khalid M. , Abdelghaffar Abdelghaffar A. , El Said Rana K. 
Published: January 2025

Background
Ultrasound is a minimally invasive diagnostic method that enables real-time sampling of the hilar and mediastinal lymph nodes.

Aim
To evaluate the role of spectral Doppler using endobronchial ultrasound (EBUS) in the differentiation of mediastinal lymph node lesions.

Patients and methods
The study was conducted at the Pulmonology Department, Faculty of Medicine, Cairo University and it was conducted between February 2023 and March 2024. The study was performed on 32 patients who had been referred to the Chest Department, Kasr El-Aini Hospital for clinical assessment; all of them have computed tomography evidence of mediastinal lymphadenopathy. All patients were subjected to history taking including age, sex, smoking, and assessment of symptoms. Clinical examination includes cervical lymph node examination, examination of neck veins and local chest examination. Computed tomography chest with i.v. contrast. Routine laboratory investigations (CBC, PT, PC, INR, liver functions, and renal functions). Ultrasound examination using spectral Doppler ultrasound and guided intervention (EBUS–TBNA) to lymph node through EBUS.

Results
Features of spectral Doppler using EBUS have a role in differentiating between malignant and benign mediastinal lymphadenopathy. These features include pulsatility index, resistive index, peak systolic velocity, end-diastolic velocity, lymph node texture, architecture, borders, invasion of surrounding structure and capsule, and vascularity. All are used as predictors that contribute to diagnosing malignant and benign mediastinal lymphadenopathy.

Conclusion
Spectral Doppler is a form of imaging using EBUS that has a role in differentiating between malignant and benign mediastinal lymphadenopathy and contributes to its diagnosis.

Authors: Ahyani Hisam , Lousada Sérgio António Neves , Solehudin Ending , Azmi Naelul , Hamzah Imron , Suganda Ahmad 
Published: January 2025

Objective: This study explores the role of progressive Islamic law in zakat distribution and its contribution to achieving Sustainable Development Goals (SDGs) in Indonesia, particularly SDG 1 (No Poverty), SDG 10 (Reduced Inequality), and SDG 16 (Peace, Justice, and Strong Institutions), through the principles of Maqasid Sharia.

Theoretical Framework: The research is grounded in Islamic law, Maqasid Sharia, and sustainable development. It examines how zakat, an Islamic obligation, can be utilized to promote justice, equality, and social welfare, aligning with SDGs to address issues like poverty and inequality.

Method: Using a qualitative approach, the study employs normative juridical analysis and a literature review of zakat management practices in Indonesia. Data is collected from academic articles, reports, and legal frameworks related to zakat distribution and its integration with SDGs.

Results and Discussion: The study finds that progressive Islamic law in zakat distribution can significantly contribute to poverty alleviation and social equity. By emphasizing Maqasid Sharia’s core principles, zakat can improve social justice and reduce inequality. However, challenges like governance, transparency, and legal alignment remain.

Research Implications: Reforming zakat management to improve governance and alignment with SDGs is essential for its effective contribution to social welfare and sustainable development.

Originality/Value: This research offers new insights on integrating Islamic law with SDGs in zakat distribution, enhancing its role in promoting social justice and economic inclusion.

Arsenic and many of its compounds are incredibly potent poisons. Arsenic-contaminated groundwater consumption is the main route of human exposure to arsenicosis. Myanmar is also affected by arsenic contamination, mainly in Ayeyarwady Division. This study aims to observe and compare the arsenic concentration of wells in the Kyanggone region with the WHO and Myanmar National Drinking Water Quality Standards (MNDWQS). MNDWQ standards. Also, this study focuses on statics results of the public awareness dealing with arsenic. Some of the wells in the Kyanggone region were tested to investigate the arsenic concentration. Survey data were collected from 138 people using the survey data collection method to know the current association of arsenic with the public in the Kyanggone region. The collected data were analysed using Statistical Package for Social Science (SPSS) software. This paper provides the results of arsenic-contaminated wells and public knowledge on arsenic and arsenic-contaminated drinking water. This study showed that knowledge and information about arsenic are still needed to know the reality and more training must be made to have more awareness of public arsenic. Also, it is claimed that a suitable, economical, and effective treatment method must be applied to prevent the public lives from arsenic poisoning.

India being a developing country has a high burden of Tuberculosis (TB). It is a communicable disease and a major global heath challenge. Considering the impact of this illness on both individual patients and public health, it is critical to comprehend the effectiveness and adverse pharmacological profile of the medications. Although most patients on a daily ATT regimen do not encounter the documented ADRs listed below, doctors and patients should be concerned about them. For example, rifampicin induced discoloration of body fluids is often overlooked as it is "innocuous". Nonetheless, Adverse drug reaction (ADRs) reports on these drugs are scarce in proportion especially in regards to the most common ADRs like antitubercular treatment (ATT) induced chromaturia.
