Published: December 2024

This study aims to optimize the queuing system at SPBU 34.41349 Karawang, Jawa Barat by using a single channel-single phase pattern model using ProModel software. An efficient and effective queuing system is essential to minimize customer waiting time and increase customer satisfaction. In this study, analyzed queue data at SPBU 34.41349 to understand the characteristics of queues and modeled them using ProModel. Identify factors affecting customer wait times and estimate queuing system performance based on simulations performed with ProModel. The results showed that the productivity rate of operators was 96% and the unemployment rate was 4%. This shows that the operator's productivity level is quite good. However, because there is only 1 filling station for motor vehicles, the type of pertalite fuel causes a buildup of queues. Therefore, to reduce queuing time and maximize service is to add one counter on each server which is expected to increase the efficiency and effectiveness of the queuing system at SPBU 34.41349 Karawang, West Java.

Published: December 2024

The purpose of this study is to assess the level of crowding in service in restaurants in Cilegon City and to propose improvements to the queue system based on the appropriate queue model for the restaurant. The method used is the Discrete Event Simulation (DES) method. The simulation approach allows for an in-depth and direct analysis of the system over a period of time, providing a realistic picture of the situation on the ground. The data used in this study is primary data, including customer arrival time data and service time (server) data measured using a stopwatch. The results of the study showed that there was a queue with an average of 10 people and a server busyness rate of 99.32%. This high level of busyness can result in a decrease in customer satisfaction due to long waiting times. Based on the results of the two scenarios tested, namely scenario one with the addition of 1 server and scenario two with the addition of 2 servers, the first scenario involving the addition of one server/cashier was chosen because it succeeded in reducing the number of customers with a busy level of 70.68%.

Laparoscopic liver resection utilizing the ventral avascular area of the inferior vena cava: A retrospective cohort study
Authors: Huang Kun , Chen Zhu , Xiao Heng , Hu Hai-Yang , Chen Xing-Yu , Du Cheng-You , Lan Xiang 
Published: December 2024

BACKGROUND
Laparoscopic liver resection (LLR) can be challenging due to the difficulty of establishing a retrohepatic tunnel under laparoscopy. Dissecting the third hepatic hilum before parenchymal transection often leads to significant liver mobilization, tumor compression, and bleeding from the short hepatic veins (SHVs). This study introduces a novel technique utilizing the ventral avascular area of the inferior vena cava (IVC), allowing SHVs to be addressed after parenchymal transection, thereby reducing surgical complexity and improving outcomes in in situ LLR.
AIM
To introduce and evaluate a novel LLR technique using the ventral avascular area of the IVC and compare its short-term outcomes with conventional methods.
METHODS
The clinical cohort data of patients with pathologically confirmed hepatocellular carcinoma or intrahepatic cholangiocarcinoma who underwent conventional LLR and novel LLR between July 2021 and July 2023 at the First Affiliated Hospital of Chongqing Medical University were retrospectively analyzed. In novel LLR, we initially separated the caudate lobe from the IVC using dissecting forceps along the ventral avascular area of the IVC. Then, we transected the parenchyma of the left and right caudate lobes from the caudal side to the cephalic side using the avascular area as a marker. Subsequently, we addressed the SHVs and finally dissected the root of the right hepatic vein or left hepatic vein. The short-term postoperative outcomes and oncological results of the two approaches were evaluated and compared.
RESULTS
A total of 256 patients were included, with 150 (58.59%) undergoing conventional LLR and 106 (41.41%) undergoing novel LLR. The novel technique resulted in significantly larger tumor resections (6.47 ± 2.96 cm vs 4.01 ± 2.33 cm, P < 0.001), shorter operative times (199.57 ± 60.37 minutes vs 262.33 ± 83.90 minutes, P < 0.001), less intraoperative blood loss (206.92 ± 37.09 mL vs 363.34 ± 131.27 mL, P < 0.001), and greater resection volume (345.11 ± 31.40 mL vs 264.38 ± 31.98 mL, P < 0.001) compared to conventional LLR.
CONCLUSION
This novel technique enhances liver resection outcomes by reducing intraoperative complications such as bleeding and tumor compression. It facilitates a safer, in situ removal of complex liver tumors, even in challenging anatomical locations. Compared to conventional methods, this technique offers significant advantages, including reduced operative time, blood loss, and improved overall surgical efficiency.
Real-world evidence on the efficacy and safety of vonoprazan-amoxicillin dual therapy for Helicobacter pylori treatment in elderly patients
Authors: Gao Wen , Li Jing-Wen , Ye Hui , Zhang Xue-Zhi , Liu Jian-Xiang , Cheng Hong 
Published: December 2024

BACKGROUND
A dual therapy regimen containing amoxicillin is a common treatment option for the eradication of Helicobacter pylori (H. pylori ). While substantial research supports the efficacy and safety of vonoprazan and amoxicillin (VA) dual therapy in the general population, there is still a lack of studies specifically focusing on its safety in elderly patients.
AIM
To evaluate efficacy and safety of VA dual therapy as first-line or rescue treatment for H. pylori in elderly patients.
METHODS
As a real-world retrospective study, data were collected from elderly patients aged 60 years and above who accepted VA dual therapy (vonoprazan 20 mg twice daily + amoxicillin 1000 mg thrice daily for 14 days) for H. pylori eradication in the Department of Gastroenterology at Peking University First Hospital between June 2020 and January 2024. H. pylori status was evaluated by 13C-urease breath test 6 weeks after treatment. All adverse events (AEs) during treatment were recorded.
RESULTS
In total, 401 cases were screened. Twenty-one cases were excluded due to loss to follow-up, lack of re-examination, or unwillingness to take medication. The total of 380 included cases comprised 250 who received VA dual therapy as first-line treatment and 130 who received VA dual therapy as rescue treatment. H. pylori was successfully eradicated in 239 cases (95.6%) in the first-line treatment group and 116 cases (89.2%) in the rescue treatment group. The overall incidence of AEs was 9.5% for both groups. Specifically, 9.2% of patients experienced an AE in the first-line treatment group and 10.0% in the rescue treatment group. Five patients discontinued treatment due to AE, with a discontinuation rate of 1.3%. No serious AE occurred.
CONCLUSION
The VA dual therapy regimen as a first-line treatment and a rescue therapy was effective and safe for elderly patients aged 60 and older.
Class-Imbalanced Machinery Fault Diagnosis Using Heterogeneous Data Fusion Support Tensor Machine
Authors: Min Zhishan , Shao Minghui , Shao Haidong , Liu Bin 
Published: December 2024

The monitoring signals of bearings from single-source sensor often contain limited information for characterizing various working condition, which may lead to instability and uncertainty of the class-imbalanced intelligent fault diagnosis. On the other hand, the vectorization of multi-source sensor signals may not only generate high-dimensional vectors, leading to increasing computational complexity and overfitting problems, but also lose the structural information and the coupling information. This paper proposes a new method for class-imbalanced fault diagnosis of bearing using support tensor machine (STM) driven by heterogeneous data fusion. The collected sound and vibration signals of bearings are successively decomposed into multiple frequency band components to extract various time-domain and frequency-domain statistical parameters. A third-order heterogeneous feature tensor is designed based on multi sensors, frequency band components and statistical parameters. STM based intelligent model is constructed to preserve the structural information of the third-order heterogeneous feature tensor for bearing fault diagnosis. A series of comparative experiments verify the advantages of the proposed method.

Mars Gravity Field Determination Based on Satellite-to-Satellite Tracking Technique
Authors: Yan Jianguo , Wang Chongyang , Zhu Xinbo , Liu Shanhong , Barriot Jean-Pierre 
Published: December 2024

Abstract
The Martian gravity field serves as the primary constraint for modeling the interior structure and changes in the surface mass. Currently, the determination of the Martian gravity field relies on ground-based tracking measurements, such as range and Doppler, conducted between Earth stations and Mars orbiters. However, these tracking methods encounter limitations in terms of observation accuracy and signal attenuation. Given the successful application of the satellite-to-satellite tracking technique in determining Earth's gravity field, as well as improving the resolution of the lunar gravity field, this paper explores its potential application to the determination of the Martian static gravity field. The objective of this research is to employ numerical simulation to assess the improvement in the precision of the Martian static gravity field achievable with the low–low satellite-to-satellite tracking (ll-SST) technique, considering various conditions, including observation durations, measurement noises, and orbital altitudes. The findings show that the intersatellite ranging system considerably enhances the global resolution of the gravity field, using the ll-SST technique at an orbital altitude of 300 km and a SST measurement noise of 1 μm s−1, the global resolution can reach at least degree 120. Reducing the measurement noise by an order of magnitude can increase the global resolution of the gravity field by 20 degrees for 300 km altitudes, and 16 degrees for 400 km altitudes. Reducing the orbital altitude by 100 km (from 400 to 300 km) results in a 20 degrees improvement in the global resolution of the gravity field.
131 and 304 Å Emission Variability Increases Hours Prior to Solar Flare Onset

Published: December 2024

Abstract
Thermal changes in coronal loops are well studied, both in quiescent active regions and in flaring scenarios. However, relatively little attention has been paid to loop emission in the hours before the onset of a solar flare; here, we present the findings of a study of over 50 off-limb flares of Geostationary Operational Environmental Satellite class C5.0 and above. We investigated the integrated emission variability for Solar Dynamics Observatory Atmospheric Imaging Assembly channels 131, 171, 193, and 304 Å for 6 hr before each flare and compared these quantities to the same time range and channels above active regions without proximal flaring. We find significantly increased emission variability in the 2–3 hr before flare onset, particularly for the 131 and 304 channels. This finding suggests a potential new flare prediction methodology. The emission trends between the channels are not consistently well correlated, suggesting a somewhat chaotic thermal environment within the coronal portion of the loops that disturbs the commonly observed heating and cooling cycles of quiescent active region loops. We present our approach and the resulting statistics and discuss the implications for heating sources in these preflaring active regions.
Heurs et malheurs des manuscrits : un rapport de l’Académie royale des sciences dans l’Encyclopédie
Authors: Passeron Irène 
Published: December 2024

Que nous apprennent les manuscrits du XVIIIe siècle ? Ou plutôt, que nous apprend le fait que certains manuscrits soient copiés, conservés, archivés, transmis, utilisés, dérobés ou perdus ? En enquêtant sur un rapport de l’Académie royale des sciences publié in extenso dans l’Encyclopédie, fait exceptionnel, nous remonterons au protocole de production de telles pièces manuscrites, au rôle de légitimation qu’elles jouent, pour l’institution qui les réglemente, comme pour les acteurs sociaux qui en bénéficient et les éditeurs qui les impriment. Le témoin principal dans cette investigation est le rapport produit par D’Alembert, Courtivron et Vaucanson pour le mémoire de Guillotte en 1748, publié ultérieurement dans l’Encyclopédie dans l’article Pont militaire.
« Frère Platon » : Diderot et le modèle en 1758
Authors: Chartier Pierre 
Published: December 2024

Alors qu’il vit une crise intense en 1758, Diderot réexamine dans le Discours sur la poésie dramatique la question du modèle. La XVIIe et dernière section, intitulée « Des auteurs et des critiques », pose le problème de son rapport à Platon en articulant la théorisation du modèle à la fois à un retour sur soi et à une sortie hors de soi. Après avoir retracé la formation de Diderot et le contexte dans lequel ce texte a été écrit, cette étude propose de lire la section XVII comme un discours diderotien de la méthode : au centre de ce discours, le mot modèle revient 15 fois, à quoi il faut ajouter des termes proches comme mesure, module, modifier. Pensés à partir de l’idée platonicienne, les modèles ne sont pas des universaux scolastiques. Ils procèdent d’une expérience humaine, que l’artiste entreprend de modifier pour constituer son modèle, centré sur la figure et sur le corps-statue. Le processus de modification suppose des modèles intermédiaires, développés à la faveur d’un entretien avec soi-même. Les situations imaginées par Richardson, les sites de Vernet, dans leur multiplicité, constituent ces modèles, à la manière des productions du Dieu créateur, mais dans le même temps selon un processus profondément humain : le modèle de l’artiste est le philosophe vivant parmi et pour les hommes.
Le modèle antique dans le projet de réforme théâtrale de Diderot
Authors: Brunet Mathieu 
Published: December 2024

La théorie de Diderot sur le théâtre trouve, on le sait, une caution récurrente dans les textes anciens : sur l’écriture, la voix, le jeu, l’espace scénique, presque toutes ses préconisations de renouvellement du théâtre s’autorisent des auteurs grecs et latins. Cette étude, reprenant des aspects souvent soulignés par la critique du côté de l’esthétique théâtrale, vise à montrer que c’est aussi une politique du théâtre que Diderot invente en la référant au modèle antique, dans laquelle le rapport entre spectacle et public transforme en profondeur la nature même du théâtre.
Contextualisation et critique des documents en classe d’histoire
Authors: Cariou Didier , Coutant Marie 
Published: December 2024

Cet article étudie les processus à l’œuvre lorsque des élèves exercent leur esprit critique pour lire des documents en classe d’histoire, conformément aux attentes de l’institution scolaire. Deux séances menées dans deux classes de CM2 (élèves âgés de 10 ans) sont analysées avec les concepts de la Théorie de l’action conjointe en didactique (TACD). La première séance permet d’étudier les modalités de lecture d’un seul document d’archives qui évoque un incident dans un tramway à Bordeaux en 1942. La deuxième séance permet d’analyser les modalités de lecture de l’ensemble du dossier d’archives concernant cet incident. D’une séance à l’autre, le problème travaillé est transformé et il devient nécessaire de convoquer la pluralité des échelles du contexte historique (le contexte particulier de l’incident, le contexte intermédiaire de la Collaboration administrative qui a produit ces archives et le contexte général du génocide des juifs). La prise en compte des échelles contextuelles conduit les élèves à travailler le problème en jeu dans ces documents pour en effectuer une lecture critique.

Authors: Enthoven Simon , Dupriez Vincent , März Virginie 
Published: December 2024

La littérature scientifique sur le développement professionnel des enseignants identifie l’établissement scolaire et son collectif enseignant comme vecteur d’apprentissage professionnel. Notre étude compréhensive interroge le rôle de l’établissement scolaire parmi les multiples opportunités d’apprentissage offertes aux enseignants, en assumant une vision multispatialisée du lieu de travail des enseignants. Les résultats de l’analyse de 37 entretiens semi-directifs d’enseignants expérimentés invitent à penser l’apprentissage en situation de travail des enseignants comme un paysage d’apprentissage professionnel au sein duquel les enseignants adoptent différentes postures et trajectoires d’apprentissage.
