La viande jeune et tendre dans l’Occident islamique médiéval à la croisée des données textuelles et matérielles
Authors: Brisville Marianne
Published: January 2024

L’histoire de l’alimentation de l’Occident islamique médiéval s’est longtemps écrite à partir de la documentation textuelle. Bien que rares et dispersés, les différents genres littéraires d’al‑Andalus et du Maghreb apportent des données complémentaires pour comprendre la place des denrées d’origine animale dans les habitudes alimentaires. Toutefois, leur vision partielle et leur dimension discursive requièrent d’être confrontées aux données matérielles que renouvellent de manière décisive les disciplines archéologiques. En adoptant une démarche pluridisciplinaire, l’article questionne la consommation des viandes jeunes et tendres, grâce à l’analyse croisée des traités arabes (médicaux, juridiques, agronomiques et culinaires) et des vestiges osseux découverts dans la péninsule Ibérique. La détermination lexicale et ostéologique des cohortes contribue ainsi à estimer l’importance socio‑économique et socio‑culturelle conférée aux cheptels dans les pratiques alimentaires, les stratégies agro‑pastorales et dans les représentations des communautés médiévales.
Prácticas culinarias y cambio social en madīnat Qurṭuba (siglos VIII‑XI)
Authors: García García Marcos , Moreno García Marta
Published: January 2024

La alimentación representa un ámbito de la experiencia humana profundamente influido por disposiciones de naturaleza social y cultural, al ser un medio expresivo de identidad que nos define en relación a otros individuos y grupos. Por ello, a partir del estudio de los restos materiales derivados del consumo con fines culinarios de los productos animales en el pasado, podemos acceder al conocimiento de los hábitos de alimentación y, de esta forma, acercarnos a la identidad sociocultural de los agentes responsables de la generación de dichos residuos. En este trabajo se presentan algunos de los resultados fruto de una investigación que situó el foco de interés sobre el análisis arqueozoológico de una serie de asociaciones faunísticas identificadas como desechos de alimentación y recuperadas en dos sectores integrados en la actual ciudad de Córdoba (Andalucía) como son el arrabal de Šaqunda (s. VIII‑IX) y la Zona Arqueológica de Cercadilla (s. VIII‑XI). En concreto, y sobre la base de las informaciones derivadas del análisis taxonómico –que nos informa sobre las principales especies consumidas– y de las técnicas de preparación del alimento inferidas a partir del examen de las marcas de carnicería y de combustión, se pretende contribuir al estudio de los hábitos de elaboración culinaria y consumo cárnico en la capital de al‑Andalus durante la fase formativa de la nueva sociedad andalusí y, en último término, demostrar la validez de esta aproximación analítica en la investigación sobre el cambio social operado en dicho contexto histórico.
Analysis of Ship Structure with GFRP Lamination Design Subjected to Underwater Shock Loading

Published: January 2024

FRP composite materials are still being continuously developed and researched, because FRP composite materials are non-magnetic and have good wave permeability, which can effectively achieve stealth and reduce the chance of being attacked. The underwater explosion impact of warships is a severe high-strain rate response. At present, most of the structural response simulations of underwater explosions are simulated with static material parameters. The static material parameters and dynamic material parameters in the tensile direction are obtained through the MTS material testing machine and the Hopkinson bar, and the other direction material parameters are obtained with Compose IT developed by BV certification. The results show that under the dynamic material parameters of LT800/M225 composite material with high strain rate, the stress and strain are both higher than those of the static test, and the stress-strain curves also have obvious differences in trends. Obtain the static and dynamic material parameters of LT800/M225, use ABAQUS to simulate the underwater explosion of the simplified ship model, and use the Tsai-Hill failure criterion to judge the material damage. The research results show that the failure time of the static or dynamic material parameters is similar, but the strain response of the dynamic material parameter simulation is more obvious than that of the static material parameter analysis. The research results of this paper can be used as a reference for subsequent research by composite material structure designers.
Extraction of Crude Bromelain from Pineapple (Ananas comosus L.) Fruit Waste and it’s in vitro Protein Digestibility
Authors: Wiboonsirikul J. , Klahan R. , Khuwijitjaru P.
Published: January 2024

Purpose:  Crude bromelain is abundant in pineapple fruit waste and is possible to use in shrimp farming. The objectives of this present study were to investigate extraction conditions and to evaluate in vitro protein digestibility of the shrimp feed supplemented with the crude bromelain extract.Research Method: Crude bromelain was extracted from pineapple fruit waste with either distilled water or tap water and the pH was adjusted, ranging from 5 to 9. The different ripeness stages and weight ratios of waste to water were further investigated. The highest proteolytic and specific proteolytic activities of the extract were selected for suitable extraction conditions. The in vitro protein digestibility of soybean meal and shrimp feed pretreated with crude bromelain extract was evaluated to determine their feasibility to use in shrimp farming.Findings: The crude bromelain derived from the pH 7 preboiled tap water extract exhibited the highest values of both proteolytic activities. The weight ratio of fruit waste to water of 1:0.5 and a ripeness stage of more than 50% yellow peel were the conditions suitable to obtain the highest values of both activities. The in vitro protein digestibility of shrimp feed pretreated with crude bromelain was 68.68 ± 2.70 %, which indicated promotion capability for protein digestion in shrimp during shrimp farming.Research Limitations: A suitable crushing tool for pineapple peel was not available. Therefore, the fragments after crushing the peel were not consistent. Originality/Value: The crude bromelain can be extracted with tap water and used to supplement shrimp feed for the promotion of digestibility.
TLR4 Ligands in Typhoid Vi Polysaccharide Subunit Vaccines Contribute to Immunogenicity
Authors: Alugupalli Kishore R
Published: January 2024

Activation of B cells and T cells requires the engagement of costimulatory signaling pathways in addition to Ag receptor signaling for efficient immune responses. None of the typhoid Vi polysaccharide (ViPS) subunit vaccines contains adjuvants that could activate costimulatory signaling pathways, yet these vaccines are very immunogenic. I hypothesized that residual TLR ligands present in the ViPS preparation used for making typhoid subunit vaccines account for the robust immune response generated by these vaccines. I show the presence of endotoxin, a potent agonist of TLR4, in ViPS preparations and ViPS vaccines. Furthermore, I found that ViPS obtained from various sources induces the production of proinflammatory cytokines such as IL-6 from mouse peritoneal exudate cells. Unconjugated and tetanus toxoid–conjugated ViPS vaccines activate human and mouse TLR4. Mice deficient in TLR4 or the signaling adaptors MyD88 and Trif (Toll/IL-1R domain–containing adapter inducing IFN-β) are severely impaired in generating anti-ViPS responses to these vaccines. Elimination of the TLR4 agonist in ViPS preparation resulted in the loss of immunogenicity, and addition of lipid A, a known TLR4 agonist, restored the immunogenicity. These data highlight the importance of associated TLR ligands in the immunogenicity of ViPS subunit vaccines.

Published: January 2024

Incontinentia pigmenti (IP) is a rare X-linked dominant neuroectodermal dysplasia affecting almost exclusively females. It is caused by loss-of-function mutations in the inhibitor of kappa light polypeptide gene enhancer in B cells, kinase gamma gene, formerly known as NF-κB essential modulator. The disorder is typically identified by peculiar skin findings that develop throughout the 1st year of life. Approximately one-third of patients has ocular and neurologic abnormalities causing severe disability. Defects of hair, nails, and teeth can also occur. Among systemic complications, pulmonary arterial hypertension (PAH) is uncommon but potentially life-threatening. Only six cases have been described in the literature so far, and four of them died before reaching 1 year of age. Herein, we report the case of a 2-month-old girl with IP and severe PAH, successfully treated with pulmonary antihypertensive and anti-inflammatory therapy.

Authors: Fakhri Dicky , Busro Pribadi Wiranda , Rahmat Budi , Purba Salomo , Lilyasari Oktavia , Asou Toshihide
Published: January 2024

Background:

By rerouting the systemic venous return into the pulmonary circulation, the Fontan operation is perhaps the most effective palliative procedure in patients with complex congenital heart disease. The Fontan, however, still comes with several significant complications and morbidities, one of them being postoperative prolonged pleural effusion. In our center from 2017 to 2021, 10% of all our patients who underwent Fontan operation developed prolonged pleural effusion. With this study, we aimed to analyze the preoperative use of sildenafil for 6 months and its role in prolonged pleural effusion after the Fontan operation.

Materials and Methods:

In total, 158 patients were included in the analysis. The cohort was divided into patients who developed prolonged pleural effusion after Fontan surgery (n = 17) and those who did not (n = 141). We analyzed several risk factors and the history of sildenafil use in each group in the cohort. We found that patients who used sildenafil for at least 6 months prior to Fontan surgery versus those who did not use (n = 112 vs. n = 46) were found to be at lower risk of developing prolonged pleural effusion (odds ratio [OR]: 0.32 [confidence interval 95%: 0.11–0.88], P = 0.027).

Conclusion:

Preoperative administration of sildenafil for at least 6 months before Fontan might reduce the risk of postoperative prolonged pleural effusion.
Left pulmonary artery reconstruction using cryopreserved pulmonary homograft
Authors: Talwar Sachin , Jha Pratik Kumar , Choudhury Arindam , Satsangi Amitabh , Choudhary Shiv Kumar
Published: January 2024

In patients with univentricular heart, the Fontan procedure is the final palliation. This is usually staged. A systemic-to-pulmonary artery shunt is performed in the presence of episodes of cyanotic spells in the neonatal period or in some patients in infancy; a bidirectional superior cardiopulmonary anastomosis is preferred early in life. This is followed by the final Fontan palliation on an elective basis later. For an effective bidirectional superior cavopulmonary anastomosis and Fontan palliation, good-sized confluent pulmonary arteries (PAs) are mandatory in addition to favorable hemodynamic data. Patients with discontinuous PAs that are small in size present a surgical challenge at initial palliation as the one described in this report.
Elevated Fras1-related extracellular matrix 3 in isocitrate dehydrogenase 1-mutant astrocytoma World Health Organization grade 4 predicts favorable prognosis in glioma: A bioinformatic and experimental analysis
Authors: Zhang Zuoxin , Huang Guohao , Wang Tingting , Pei Yuchun , Liu Guolong , Yang Lin , Xiang Yan , Chen Qiuzi , Zhou Shuo , Zhou Xingyu , Zheng Xiaoyang , Lv Shengqing
Published: January 2024

Background and Aim:

World Health Organization (WHO) grade 4 glioma is a malignancy of the central nervous system characterized by refractoriness to treatment and a high mortality rate. Isocitrate dehydrogenase (IDH) mutation is a crucial molecular event for the classification of glioma and associated with prognosis and exploring genetic and molecular differences between IDH mutant and wildtype glioma is crucial. The aim of this study was to investigate the prognostic gene between IDH mutant and wildtype WHO grade 4 glioma and its functional significance.

Materials and Methods:

The mRNA expression profile data of WHO grade 4 glioma were downloaded from the Gene Expression Omnibus and Chinese Glioma Genome Atlas databases. Bioinformatic analysis was performed to identify the differentially expressed genes between IDH1-mutant and wildtype WHO grade 4 glioma. Survival analysis, functional enrichment analysis, immune cell infiltration evaluation, and in vitro experimental validation were conducted to evaluate the prognostic and functional significance of Fras1-related extracellular matrix 3 (FREM3). This study was approved by the Institutional Ethics Committee of Xinqiao Hospital, Third Military Medical University (approval No. 2021-Y068-01).

Results:

Elevated expression of FREM3 in IDH1-mutant WHO grade 4 astrocytoma predicted favorable prognosis in glioma. FREM3 was negatively associated with epithelial–mesenchymal transition (EMT), angiogenesis, and hypoxia; notably, low expression of FREM3 was associated with a higher degree of immune cell infiltration. In vitro experiments demonstrated that high FREM3 expression might attenuate the process of EMT and cellular proliferation in glioma.

Conclusions:

The gene FREM3 plays a major role in IDH1-mutant WHO grade 4 glioma and elevated FREM3 predicts a favorable prognosis of glioma. Further investigation on FREM3 is warranted to elucidate the mechanisms underlying the malignant evolution of glioma.
Evaluation of Esophageal Motility in Obese Patients before and after Bariatric Surgery: Role of Multichannel Intraluminal Impedance and High-resolution Manometry
Authors: Roque Leticia , Mota Gustavo De Assis , Nonino Carla B. , Salgado Júnior Wilson
Published: January 2024

Background:

A high prevalence of esophageal motor disorders has been reported in obese patients. Roux-en-Y gastric bypass (RYGB) can trigger symptoms of dysphagia by worsening preexisting esophageal motor disorders. Investigation of esophageal motility with multichannel intraluminal impedance (MII) and high-resolution manometry (HRM) is available.

Objective:

The aim is to compare the results of MII and HRM of nonobese patients with those of obese patients before and after RYGB to identify possible preoperative predictive factors of postoperative dysphagia.

Materials and Methods:

Twenty-eight obese patients were evaluated with a questionnaire of symptoms, endoscopy, HRM, and MII in different postures (supine and sitting) before and 6 months after laparoscopic RYGB. They were compared with eleven nonobese subjects. Chicago classification parameters were used to characterize esophageal motility disorders.

Results:

Obese patients evolved with more symptoms of dysphagia after surgery (7.10% preoperatively and 32.10% postoperatively). None had gastrojejunal anastomosis stenosis. After bariatric surgery, there was an increase in distal latency (HRM) and also a decrease in esophageal alimentary bolus progression (MII). Twenty-one percent of obese patients already had some dysmotility before the surgery and 92% of them evolved to dysphagia after the operation.

Conclusions:

Previous esophageal motility disorder is a good predictive factor of postoperative dysphagia. HRM and MII should be performed in some situations, such as bariatric surgery for older adults and before narrowing the gastrojejunal anastomosis as a treatment for weight recidivism.

Authors: Padwal Viraj Sudam , Bhalerao Pradnya , Pawar Smita A.
Published: January 2024

Context:

Glaucoma is the second leading cause of world blindness. Considering the scarcity of glaucoma studies in the Western part of Maharashtra, we conducted this study to determine the prevalence of glaucoma among adults aged 18 years and above.

Aims:

To determine the prevalence and clinical profile of glaucoma in rural-based Tertiary Care Hospital.

Settings and Design:

A cross-sectional study carried out in an Ophthalmology outpatient department in a rural-based Tertiary care hospital.

Materials and Methods:

Five hundred and eighty-three patients underwent ocular examination including visual acuity, slit-lamp examination, optic disc evaluation with +78D lens and intraocular pressure measurement with Goldmann applanation tonometer, gonioscopy, visual fields examination by Humphrey Field Analyzer and optic nerve head analysis using optical coherence tomography scan of all the glaucoma suspects.

Statistical Analysis Used:

The data of patients were tabulated and analyzed using SPSS.

Results:

Out of 583 cases, 42 cases had primary glaucoma; thus, the overall prevalence of glaucoma was found to be 7.2%. The open-angle group had 38 (90.4%) cases, whereas the narrow-angle group had 4 (9.52%) cases. Out of the total of 113 hypertensive patients, 16 were found to have glaucoma (38.09%, P < 0.01), and out of 84 diabetic patients, 14 cases were glaucomatous (33.33%, P < 0.01). The prevalence of glaucoma was found to be significantly associated with a positive family history, as 6 cases (14.3%) out of 42 had a positive family history (P < 0.01).

Conclusions:

The prevalence of glaucoma was found to be high in the population of the rural Western part of Maharashtra. Screening for glaucoma among middle-aged people with a positive family history, hypertension, and diabetes would help us in the early diagnosis and management of this irreversible disease.
Efficacy of topical low-dose atropine eye drops (0.01%) in slowing myopia progression in school-age children
Authors: Bansal Yashi , Grover Renu , Chakraborty Rakesh
Published: January 2024

Purpose:

To study the effect of low-dose topical atropine eye drops (0.01%) in slowing myopia progression in school-age children.

Methods:

This was a prospective randomized controlled study, in children in the age group of 5–15 years, with myopic refractive error (spherical equivalent) between −1.0D and −5.0D at the time of presentation. A total of 100 patients were studied and randomly divided into two groups of 50 each: the control group and the atropine group. They were followed up 3 monthly for cycloplegic refraction, axial length (AL), pupil size, accommodation, and binocular stereopsis for near for a time period of 2 years.

Results:

Over a period of 2 years, there was a statistically significant decrease in the progression of myopic spherical equivalent and the AL in the atropine group. The accommodation and binocular stereopsis were comparable in both the groups. There was an average 0.7 mm increase in pupillary size posttreatment in the atropine group.

Conclusions:

The results of our study indicated that topical atropine (0.01%) is effective in retarding myopia progression at the end of 2 years of treatment. No child experienced allergic reaction, difficulty in reading, or photophobia during the trial period. Thus, atropine eye drops (0.01%) can be considered safe and efficacious in reducing the progression of myopia.

ABSTRACT

Objective:

This study aimed to evaluate the effect of child-friendly dentist attire and camouflage syringes on reducing dental anxiety in children.

Methods:

A cross-sectional study was conducted with 120 pediatric patients aged 6 to 12 years. Participants were assigned to one of three groups: group A (child-friendly dentist attire), group B (camouflage syringe), or group C (control group). Child preference for dentist attire was assessed using a visual analog scale, while dental anxiety was measured using the Modified Child Dental Anxiety Scale and the Facial Image Scale.

Results:

The results showed a significant decrease in dental anxiety scores in both group 2 and group 3 compared to group 1 (P < 0.001). Children in group A exhibited a higher preference for child-friendly dentist attire [mean score: 8.7, standard deviation (SD): 1.2] compared to group 1 (mean score: 3.2, SD: 1.5) (P < 0.001). Similarly, children in group 2 showed a higher preference for a camouflage syringe (mean score: 8.5, SD: 1.3) compared to group 1 (mean score: 3.4, SD: 1.6) (P < 0.001)

Conclusion:

Child-friendly dentist attire and camouflage syringes were found to be effective in reducing dental anxiety among pediatric patients. These interventions were well received by children and their parents, highlighting the importance of considering child preferences in dental settings.
Comparison of diagnostic accuracy of conventional method and Bethesda system for reporting thyroid cytopathology in the diagnosis of various lesions of the thyroid: Experience from a tertiary care center of northeastern India
Authors: Rahman Mustafizur , Bhuyan Geet , Duarah Bobby , Saikia Projnan
Published: January 2024

Background:

Fine-Needle Aspiration Cytology (FNAC) is a valuable, minimally invasive diagnostic tool for discerning benign and malignant thyroid lesions. In the realm of thyroid cytopathology, both the traditional approach and the Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) are widely utilized for diagnosing and categorizing these lesions.

Aims and Objectives:

This study aims to classify thyroid cytology smears using both the conventional method and the Bethesda system and to compare their findings with histopathological diagnoses.

Method and Materials:

A hospital-based cross-sectional study was conducted over one year, spanning from February 1, 2022, to January 31, 2023. We included 191 cases of FNAC thyroid lesions and categorized them following the guidelines of both the conventional system and the Bethesda system for reporting thyroid cytopathology. Sensitivity, specificity, accuracy, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy for both systems were calculated, with histopathology serving as the gold standard for comparison. Furthermore, we calculated the Risk of Malignancy (ROM) for each category within the Bethesda system.

Results:

The Bethesda system exhibited a notably high sensitivity of 83.33%, surpassing the conventional method's sensitivity of 50%, while both systems shared the same specificity of 90%. The diagnostic accuracy of the Bethesda system, at 89.13%, outperformed that of the conventional method, which stood at 84.78%.

Conclusion:

This study demonstrates a strong positive correlation with histopathology, indicating high sensitivity, specificity, and accuracy when employing TBSRTC, in contrast to the conventional method.

On the bifurcation of solutions to Marguerre–von Kármán equations
Authors: Bendob Tourkia , Ghezal Abderrezak
Published: January 2024

The objective of this work is to study the bifurcation of solutions of the Marguerre–von Kármán equations, which constitute a mathematical model for the buckling of Marguerre–von Kármán shallow shells. More precisely, we reduce the Marguerre–von Kármán equations to a single equation with a cubic operator; its second member depends on the function that defines the middle surface of the shallow shell and the applied forces. Next, we prove a general existence theorem for the reduced equation, by using the main theorem on pseudomonotone operators. Then we study the bifurcation of solutions in the reduced equation, with a second member, is small, at neighborhood of the simple characteristic value of the linearized problem.
A uniform model for Kirillov―Reshetikhin crystals
Authors: Lenart Cristian , Naito Satoshi , Sagaki Daisuke , Schilling Anne , Shimozono Mark
Published: January 2024

We present a uniform construction of tensor products of one-column Kirillov–Reshetikhin (KR) crystals in all untwisted affine types, which uses a generalization of the Lakshmibai–Seshadri paths (in the theory of the Littelmann path model). This generalization is based on the graph on parabolic cosets of a Weyl group known as the parabolic quantum Bruhat graph. A related model is the so-called quantum alcove model. The proof is based on two lifts of the parabolic quantum Bruhat graph: to the Bruhat order on the affine Weyl group and to Littelmann's poset on level-zero weights. Our construction leads to a simple calculation of the energy function. It also implies the equality between a Macdonald polynomial specialized at $t=0$ and the graded character of a tensor product of KR modules.

Nous présentons une construction uniforme pour les produits tensoriels des cristaux de Kirillov–Reshetikhin de type colonne, pour tous les types affines symétriques, qui utilise une généralisation des chemins de Lakshmibai–Seshadri (dans la théorie des chemins de Littelmann). Cette généralisation est basée sur un graphe sur les classes paraboliques d’un groupe de Weyl appelé le graphe de Bruhat parabolique quantique. Un modèle lié est le modèle des alcôves quantiques. La preuve est basée sur deux relèvements du graphe de Bruhat parabolique quantique : dansl’ordre de Bruhat affine et dans un ensemble ordonné des poids de niveau zéro. Notre construction donne une formule simple pour la fonction d’énergie. Elle donne aussi l’égalité d’un polynôme de Macdonald spécialisé à $t=0$ avec le caractère gradué d’un produit tensoriel des modules de Kirillov–Reshetikhin.
Euler flag enumeration of Whitney stratified spaces
Authors: Ehrenborg Richard , Goresky Mark , Readdy Margaret
Published: January 2024

We show the $\mathrm{cd}$-index exists for Whitney stratified manifolds by extending the notion of a graded poset to that of a quasi-graded poset. This is a poset endowed with an order-preserving rank function and a weighted zeta function. This allows us to generalize the classical notion of Eulerianness, and obtain a $\mathrm{cd}$-index in the quasi-graded poset arena. We also extend the semi-suspension operation to that of embedding a complex in the boundary of a higher dimensional ball and study the shelling components of the simplex.

Nous montrons le $\mathrm{cd}$-index existe pour les manifolds de Whitney stratifiées en élargissant la notion d’un poset gradué à celle qu'un poset quasi-gradué. C’est un poset doté d'une fonction de rang que préservant l’ordre du poset et une fonction de zêta pondérée. Ceci nous permet de généraliser la notion classique de “Eulerianness”, et obtenir un $\mathrm{cd}$-index dans l’arène des posets quasi-gradués. Nous tenons également à l’opération de semi-suspension pour que d’intégrer une complexe dans la frontière d’une balle de dimension supérieur et étudions les composants shelling d’un simplex.
On r-stacked triangulated manifolds
Authors: Murai Satoshi , Nevo Eran
Published: January 2024

The notion of $r$-stackedness for simplicial polytopes was introduced by McMullen and Walkup in 1971 as a generalization of stacked polytopes. In this paper, we define the $r$-stackedness for triangulated homology manifolds and study their basic properties. In addition, we find a new necessary condition for face vectors of triangulated manifolds when all the vertex links are polytopal.

Généralisant les polytopes simpliciaux empilés, McMullen et Walkup ont introduit en 1971 la notion de $r$-empilement pour les polytopes simpliciaux. Dans cet article, nous définissons la notion de $r$-empilement pour les variétés homologiques simpliciales et étudions ses propriétés élémentaires. En outre, nous donnons une nouvelle condition pour les $f$-vecteurs des variétés simpliciales lorsque tous les sommets ont un lien polytopal.
Structure and enumeration of $(3+1)$-free posets (extended abstract)
Authors: Guay-Paquet Mathieu , Morales Alejandro H. , Rowland Eric
Published: January 2024

A poset is $(3+1)$-free if it does not contain the disjoint union of chains of length 3 and 1 as an induced subposet. These posets are the subject of the $(3+1)$-free conjecture of Stanley and Stembridge. Recently, Lewis and Zhang have enumerated $\textit{graded}$ $(3+1)$-free posets, but until now the general enumeration problem has remained open. We enumerate all $(3+1)$-free posets by giving a decomposition into bipartite graphs, and obtain generating functions for $(3+1)$-free posets with labelled or unlabelled vertices.

Un poset sans $(3 + 1)$ est un poset qui n’a pas de sous-poset induit formé de deux chaînes disjointes de longueur 3 et 1. Ces posets sont l’objet de la conjecture $(3+1)$ de Stanley et Stembridge. Récemment, Lewis et Zhang ont énuméré les posets $\textit{étagés}$ sans $(3 + 1)$, mais en général la question d’énumération est restée ouverte jusqu'à maintenant. Nous énumérons tous les posets sans $(3 + 1)$ en donnant une décomposition de ces posets en graphes bipartis, et obtenons des fonctions génératrices qui les énumèrent, qu’ils soient étiquetés ou non.
The explicit molecular expansion of the combinatorial logarithm
Authors: Labelle Gilbert
Published: January 2024

Just as the power series of $\log (1+X)$ is the analytical substitutional inverse of the series of $\exp (X)-1$, the (virtual) combinatorial species, $\mathrm{Lg} (1+X)$, is the combinatorial substitutional inverse of the combinatorial species, $E(X)-1$, of non-empty finite sets. This $\textit{combinatorial logarithm}$, $\mathrm{Lg} (1+X)$, has been introduced by A. Joyal in 1986 by making use of an iterative scheme. Given a species $F(X)$ (with $F(0)=1$), one of its main applications is to express the species, $F^{\mathrm{c}}(X)$, of $\textit{connected}$ $F$-structures through the formula $F{\mathrm{c}} = \mathrm{Lg} (F) = \mathrm{Lg} (1+F_+)$ where $F_+$ denotes the species of non-empty $F$-structures. Since its creation, equivalent descriptions of the combinatorial logarithm have been given by other combinatorialists (G. L., I. Gessel, J. Li), but its exact decomposition into irreducible components (molecular expansion) remained unclear. The main goal of the present work is to fill this gap by computing explicitly the molecular expansion of the combinatorial logarithm and of $-\mathrm{Lg}(1-X)$, a "cousin'' of the tensorial species, $\mathrm{Lie}(X)$, of free Lie algebras.

Tout comme la série de puissances de $\log (1+X)$ est l’inverse substitutionnel analytique de la série de $\exp (X)-1$ l’espèce de structures (virtuelle) $\mathrm{Lg} (1+X)$, est l’inverse substitutionnel combinatoire de l’espèce, $E(X)-1$, des ensembles finis non vides. Ce $\textit{logarithme combinatoire}$, $\mathrm{Lg} (1+X)$ , a été introduit par A. Joyal en 1986 en faisant appel à un schéma itératif. Étant donnée une espèce $F(X)$ (telle que $F(0)=1$), l’une de ses principales applications est d’exprimer l’espèce, $F^{\mathrm{c}}(X)$, des $F$-structures $\textit{connexes}$ par la formule $F{\mathrm{c}} = \mathrm{Lg} (F) = \mathrm{Lg} (1+F_+)$ où $F_+$ désigne l’espèce des $F$-structures non vides. Depuis sa création, des descriptions équivalentes du logarithme combinatoire ont été formulés par d’autres combinatoriciens (G. L., I, Gessel, J. Li), mais sa décomposition exacte en composantes irréductibles (développement moléculaire) est demeurée obscure. Le but principal du présent travail est de combler cette lacune en calculant explicitement le développement moléculaire du logarithme combinatoire et de $-\mathrm{Lg}(1-X)$ un “cousin” de l’espèce tensorielle, $\mathrm{Lie}(X)$, des algèbres de Lie libres.

In this paper we give a new proof of the universality of the Tutte polynomial for matroids. This proof uses appropriate characters of Hopf algebra of matroids, algebra introduced by Schmitt (1994). We show that these Hopf algebra characters are solutions of some differential equations which are of the same type as the differential equations used to describe the renormalization group flow in quantum field theory. This approach allows us to also prove, in a different way, a matroid Tutte polynomial convolution formula published by Kook, Reiner and Stanton (1999). This FPSAC contribution is an extended abstract.

Dans cet article, nous donnons une nouvelle preuve de l’universalité du polynôme de Tutte pour les matroïdes. Cette preuve utilise des caractères appropriés de l’algèbre de Hopf des matroïdes introduite par Schmitt (1994). Nous montrons que ces caractères algèbre de Hopf sont des solutions d'équations différentielles du même type que les équations différentielles utilisées pour décrire le flux du groupe de renormalisation en théorie quantique de champs. Cette approche nous permet aussi de démontrer, d’une manière différente, une formule de convolution du polynôme de Tutte des matroïdes, formule publiée par Kook, Reiner et Stanton (1999). Cette contribution FPSAC est un résumé étendu.
On some generalized $q$-Eulerian polynomials
Authors: Lin Zhicong
Published: January 2024

The $(q,r)$-Eulerian polynomials are the $(\mathrm{maj-exc, fix, exc})$ enumerative polynomials of permutations. Using Shareshian and Wachs' exponential generating function of these Eulerian polynomials, Chung and Graham proved two symmetrical $q$-Eulerian identities and asked for bijective proofs. We provide such proofs using Foata and Han's three-variable statistic $(\mathrm{inv-lec, pix, lec})$. We also prove a new recurrence formula for the $(q,r)$-Eulerian polynomials and study a $q$-analogue of Chung and Graham's restricted Eulerian polynomials. In particular, we obtain a symmetrical identity for these restricted $q$-Eulerian polynomials with a combinatorial proof.

Les $(q; r)$-polynômes Eulériens sont les polynômes énumératifs des permutations par rapport au poids $(\mathrm{maj-exc, fix, exc})$. En utilisant la fonction génératrice de ces polynômes Eulériens due à Shareshien et Wachs, Chung et Graham ont démontré deux identités symétriques $q$-Eulériennes et demandé des preuves bijectives. Nous donnons de telles preuves en utilisant les statistiques trivariées $(\mathrm{inv-lec, pix, lec})$ de Foata et Han. Nous démontrons aussi une nouvelle récurrence pour ces $(q; r)$-polynômes Eulériens et étudions un $q$-analogue des polynômes Eulériens restreints de Chung et Graham. En particulier, nous obtenons une identité symétrique pour ces $q$-polynômes Eulériens restreints avec une preuve combinatoire.

Authors: Assarf Benjamin , Joswig Michael , Paffenholz Andreas
Published: January 2024

The $d$-dimensional simplicial, terminal, and reflexive polytopes with at least $3d-2$ vertices are classified. In particular, it turns out that all of them are smooth Fano polytopes. This improves previous results of Casagrande (2006) and Øbro (2008). Smooth Fano polytopes play a role in algebraic geometry and mathematical physics. This text is an extended abstract of Assarf et al. (2012).

Early Maladaptive Schemas and Automatic Thoughts In
Sexually Dysfunctional Men
Authors: Zsuzsanna Szilágyi (Kovács)
Published: January 2024

The aim of the present study case was to show the evidence of the associations between sexual dysfunction in men and early maladaptive schemas, automatic thoughts. The major objective of this study was to identify the role of early maladaptive schemas (EMS) in male sexual functioning and clarify the way these cognitive structures differentiate men with and without sexual dysfunction. The participants of this study completed three measures evaluating YSQ (Young and Brown, 1989), Sexual Modes Questionnaire (SMQ) (Nombre&Pinto-Gouveia,2000) and The Questionnaire of Cognitive Schema Activation in Sexual Context (QCSASC, Nombre&Pinto-Gouveia,2009). Findings supported the hypothesis of a typical cognitive pattern in men with sexual difficulties. Men with sexual dysfunction reported more dependence/incompetence early maladaptive schemas and activated more difference, helpless, and particularly incompetence schemas in hypothetical unsuccessful sexual situations, in comparison to sexually healthy men. Male sexual dysfunction has long been regarded as being common. Recently, awareness of normal male sexual function and causes of sexual dysfunction have become better understood, and more effective treatments are available. Male sexual dysfunction includes erectile dysfunction, diminished libido and abnormal ejaculation. Measurement of this study was conducted separately for the dysfunctional and the control group. This study was aimed at examining the relation among the sexual performance, emotional responses, activated maladaptive schemas. Men having sexual difficulties were compared with sexually functional men to find out how the two groups of men differ from each other. The aim of this study was to see the connection between sexual dysfunction at men and maladaptive schemas/automatic thoughts. Sexually heathy men (N=3) and men with sexual dysfunction (N=3) were compared.
Oratio de incarnatione Verbi de Atanasio de Alejandría. Apuntes cristológicos sobre el misterio de la encarnación del Verbo
Authors: Morales Díaz Joaquín del Amor , Bueno Ávila Antonio
Published: January 2024

El objetivo del presente artículo es presentar los principales aspectos cristológicos contenidos en la obra Oratio de incarnatione Verbi de Atanasio de Alejandría. Para conseguir este fin, el estudio se divide en tres partes: 1) Atanasio de Alejandría, su época y su teología; 2) Relación entre Oratio contra gentes y Oratio de incarnatione Verbi; 3) Apuntes de cristología atanasiana. De esta forma, procediendo siempre de lo general a lo particular, se extraerán dos conclusiones importantes. En primer lugar, se podrá descubrir que Atanasio construye su cristología sobre distintos binomios que dan coherencia y unidad a su pensamiento. En segundo lugar, se percibirá con claridad la densidad teológica que posee el misterio de la encarnación del Verbo dentro de su doctrina.
Pengaruh Moving Average dan Transaction Volume pada Return Saham Perbankan Indonesia
Authors: Majiah Valdi Sayoga , Kelana Said
Published: January 2024

This study investigates the impact of Moving Average (MA) Stock prices and Transaction Volume on Stock returns in the Indonesian banking sector, specifically focusing on the LQ45 index from 2020 to 2023. It delves into the concepts of Efficient Market Hypothesis (EMH), Behavioral Finance, and Technical Analysis. EMH posits that Stock prices reflect all available information and are hard to consistently beat, while Behavioral Finance suggests that psychological factors can lead to market inefficiencies exploitable by technical analysis. Employing a quantitative approach and data from the Indonesia Stock Exchange (BEI), the study finds that MA and Transaction Volume positively and significantly influence Stock returns in the banking sector. However, variations exist in individual bank samples due to factors like fundamentals and unique behaviors, which cannot be solely determined from historical Stock prices. Thus, the research underscores the importance of considering additional factors beyond past price trends when analyzing the Stock performance of individual banks.
A case study with extreme low-level jet in southern Brazil
Authors: Correa Cleber Souza , De Queiroz Antônio Paulo
Published: January 2024

This study aimed to analyze a period of intense Low-Level Jets (LLJ) in southern Brazil that occurred in a year of intense El Nino-South Oscillation signal. Observational data were collected by radiosonde data carried out at Salgado Filho airport, which measured values of the order of 30 ms-1 in intensity at 700/750 meters in height and a predominant direction of 270 degrees. The LLJ’s are horizontal vortices in the low-level turbulence process, optimizing the transport of energy and water vapor at the mesoscale; they are low-cost energy structures with maximum transport efficiency. In general, their modeling by numerical models at high resolution is difficult because they have a thin layer with a small thickness of the order of 50 meters and have a non-linear nature in the turbulence processes. However, global reanalysis models, in general, cannot represent the optimization effects in the turbulent process performed by LLJ. However, there is a tendency to represent the magnitude of the wind modulus, an approximation of this value by the current state of the art in global reanalysis modeling in models, in this case, the maximum wind. This implies that global models generally underestimate flows at low levels, in general, as they do not represent the optimization effects associated with LLJ. In this case study, we tried to use an extreme situation of occurrence of LLJ for analysis, therefore, the regional climate model RegCM-4.9 in high spatial resolution was used to simulate the period from May to June 1997. The analyses were concentrated in June 1997. The initialization and boundary conditions were used from the EC-EARTH historical of the Earth system model based on the operational seasonal forecast system of the European Center for Medium-Range Weather Forecasts (ECMWF). It was observed that the simulation result could significantly underestimate the wind intensity and the processes associated with the LLJ with the initialization model, with low information resolution, the global initialization models do not have adequate resolution for this type of simulation.

Published: January 2024

Pembelajaran daring diterapkan dan dilaksanakan dengan berbagai strategi yang sering diiringi dengan penugasan yang seringkali diselesaikan dalam waktu yang bersamaan sehingga menimbulkan stres, cemas, bahkan depresi bagi mahasiswa. Tujuan penelitian untuk menganalisis penerapan pembelajaran daring terhadap tingkat stres, cemas, dan depresi pada mahasiswa. Metode penelitian menggunakan desain deskriptif korelasi dengan pendekatan cross-sectional. Instrumen penelitian:1) kuesioner penerapan pembelajarn daring; 2) Depression Anxiety Stress Scale (DASS) 42. Sampel penelitian 328 mahasiswa dari 11 program studi di Universitas Binawan yang memenuhi kriteria inklusi dengan teknik simple random sampling. Hasil penelitian pelaksanaan pembelajaran daring berada pada tingkat baik (75%), tingkat depresi mahasiswa mayoritas pada tingkat depresi normal (56,1%), tingkat kecemasan mahasiswa pada tingkat normal (33,2%), tingkat stres mahasiswa pada tingkat normal (66,8%), dengan p-value pembelajaran daring dengan tingkat depresi 0,12 (>0,05), pembelajaran daring dengan tingkat cemas 0,2 (>0,05), dan pembelajaran daring dengan tingkat stres 0,01 (<0,05). Kesimpulan tidak ada hubungan penerapan pembelajaran daring dengan tingkat depresi dan cemas, dan ada hubungan pembelajaran daring dengan tingkat stres mahasiswa di Universitas Binawan. Saran peningkatan dan pengembangan strategi dan sistem pembelajaran daring yang lebih efektif bagi mahasiswa perlu dilakukan; dan pelatihan manajemen stres bagi mahasiswa agar dapat beradaptasi dengan lebih baik dalam mengatasi stressor selama melaksanakan pembelajaran daring.
