Authors: Kumar Mukesh , Rai Rahul Kumar , Shahi Siddharth , Singh Anshdeep , Aggarwal Nidhi , Mohammad El-Shamy Fahiem Mohammad 
Published: January 2024

ABSTRACT

Background:
An important aspect of the preparation of the access cavity and biomechanical preparation of the root canal is to safeguard as much of the tooth’s framework as possible without affecting access and visibility.

Objectives:
To compare the impact of the conservative design of access preparation and traditional design of access preparation in association with TruNatomy endodontic instrumentation and WaveOne Gold endodontic instrumentation on resistance to fracture by the design of a cavity for endodontic access using finite element analysis

Materials and Methods:
Micro-CT radiographic images of 16 human first permanent molars of the mandible were included in the study to create representative finite element analysis computational models.

Results:
A significant reduction in load for failure after endodontic preparation was observed in TDAP subcategories as compared to specimens with CDAP. However, the reduction in load for failure was comparable in both endodontic instrument systems within the CDAP and TDAP

Conclusion:
A significant reduction in load for failure after endodontic preparation was observed in the traditional design of access preparation subcategories as compared to specimens with the conventional design of access preparation.
An Ex-vivo Comparative Study to Evaluate the Efficacy of Three Root Canal Irrigation Systems in Reduction of Enterococcus Faecalis
Authors: Asiri Ashwaq 
Published: January 2024

ABSTRACT

Aim:
The purpose of this ex-vivo study is to evaluate the efficacy of three irrigation techniques in the reduction of E. faecalis in root canal.

Materials and Methods:
Eighty healthy maxillary anteriors were employed in this investigation. The bacteria E. faecalis was left on teeth for 7 days while they were kept. Once teeth were contaminated, they were randomly divided into three groups of 20 for experimentation and a control group of 20 for comparison. NaviTip FX was used to irrigate Group I, the Max-I-probe was used to water Group II, and the Endovac system was used to water Group III. The number of colony forming units (CFUs) was determined by growing bacteria from root canal samples for 2 days in Brain heart infusion agar after chemo-mechanical operations.

Results:
There was a substantial decrease in bacterial numbers across all experimental groups compared to group IV (control). Group III (Endovac) had the fewest bacterial colonies among the test groups. There were no discernible changes between Group I (the Navitip FX) and Group II (the Max I probe).

Conclusion:
Endovac was the most effective of the three irrigation methods for reducing CFUs. This study’s findings lend credence to the idea that the apical negative pressure approach has more potential than the conventional irrigation delivery system for achieving an enhanced antibacterial impact.
Network parameterizations for the Grassmannian
Authors: Talaska Kelli , Williams Lauren 
Published: January 2024

Deodhar introduced his decomposition of partial flag varieties as a tool for understanding Kazhdan-Lusztig polynomials. The Deodhar decomposition of the Grassmannian is also useful in the context of soliton solutions to the KP equation, as shown by Kodama and the second author. Deodhar components $S_D$ of the Grassmannian are in bijection with certain tableaux $D$ called $\textit{Go-diagrams}$, and each component is isomorphic to $(\mathbb{K}^*)^a ×\mathbb{K})^b$ for some non-negative integers $a$ and $b$. Our main result is an explicit parameterization of each Deodhar component in the Grassmannian in terms of networks. More specifically, from a Go-diagram $D$ we construct a weighted network $N_D$ and its $\textit{weight matrix}$ $W_D$, whose entries enumerate directed paths in $N_D$. By letting the weights in the network vary over $\mathbb{K}$ or $\mathbb{K} ^*$ as appropriate, one gets a parametrization of the Deodhar component $S_D$. One application of such a parametrization is that one may immediately determine which Plücker coordinates are vanishing and nonvanishing, by using the Lindstrom-Gessel-Viennot Lemma. We also give a (minimal) characterization of each Deodhar component in terms of Plücker coordinates.
Deodhar a introduit une décomposition des variétés drapeaux pour comprendre les polynômes de Kazhdan-Lusztig. La décomposition de Deodhar des Grassmanniennes est aussi utile dans le contexte des solutions solitons de l’équation KP, ce qui a été établi par Kodama et le deuxième auteur. Les composantes de Deodhar $S_D$ sont en bijection avec certains tableaux $D$ appelés $\textit{diagrammes de Go}$, et chaque composante est isomorphe à $(\mathbb{K}^*)^a ×\mathbb{K})^b$ où $a$ et $b$ sont des entiers positifs. Notre résultat principal est une paramétrisation explicite de chaque composante de Deodhar des Grassmanniennes en termes de réseaux. Plus précisément, à partir d’un diagramme de Go $D$, nous construisons un réseau $N_D$ et sa $\textit{matrice de poids}$ $W_D$, dont les composantes énumèrent les chemins dirigés dans $N_D$. En faisantvarier les poids dans $\mathbb{K}$ ou $\mathbb{K} ^*$, nous obtenons une paramétrisation de la composante de Deodhar $S_D$. Une applicationde cette paramétrisation est que nous pouvons déterminer quelles coordonnées de Plücker s’annulent, en utilisant le lemme de Lindstrom-Gessel-Viennot. Nous donnons aussi une caractérisation minimale de chaque composante en termes de coordonnées de Plücker.
Schubert polynomials and $k$-Schur functions (Extended abstract)
Authors: Benedetti Carolina , Bergeron Nantel 
Published: January 2024

The main purpose of this paper is to show that the multiplication of a Schubert polynomial of finite type $A$ by a Schur function can be understood from the multiplication in the space of dual $k$-Schur functions. Using earlier work by the second author, we encode both problems by means of quasisymmetric functions. On the Schubert vs. Schur side, we study the $r$-Bruhat order given by Bergeron-Sottile, along with certain operators associated to this order. On the other side, we connect this poset with a graph on dual $k$-Schur functions given by studying the affine grassmannian order of Lam-Lapointe-Morse-Shimozono. Also, we define operators associated to the graph on dual $k$-Schur functions which are analogous to the ones given for the Schubert vs. Schur problem.
Le but principal de cet article est de montrer que la multiplication d’un polynôme de Schubert de type fini $A$ par une fonction de Schur peut être comprise à partir de la multiplication dans l’espace dual des fonctions $k$-Schur. Les travaux antérieurs par le second auteur, nous permet de coder ces deux problèmes au moyen de fonctions quasi-symétriques. Du côté Schubert vs Schur, nous étudions l’ordre partiel $r$-Bruhat donné par Bergeron-Sottile, ainsi que certains opérateurs associés à cet ordre. Nous donnons une relation entre l’ordre $r$-Bruhat et le graphe de Bruhat sur les fonctions $k$-Schur duales données par l’étude de l’ordre affine grassmannienne de Lam-Lapointe-Morse-Shimozono. En outre, nous définissons des opérateurs associés a ce graphe qui sont analogues à ceux donnés pour le problème Schubert vs Schur.
Adinkras for Mathematicians

Published: January 2024

$\textit{Adinkras}$ are graphical tools created for the study of supersymmetry representations. Besides having inherent interest for physicists, the study of adinkras has already shown connections with coding theory and Clifford algebras. Furthermore, adinkras offer many natural and accessible mathematical problems of combinatorial nature. We present the foundations for a mathematical audience, make new connections to other fields (homological algebra, poset theory, and polytopes), and solve some of these problems. Original results include the enumeration of all hypercube adinkras through dimension 5, the enumeration of odd dashings of adinkras for any dimension, and a connection between rankings and the chromatic polynomial for certain graphs.
Les $\textit{adinkras}$ sont des dessins qui sont utilisés pour étudier les représentations des théories supersymétriques. Outre leur intérêt en physique, les adinkras sont aussi utiles en connexion avec la théorie des codes et les algèbres de Clifford. De plus, les adinkras offrent beaucoup de problèmes de nature combinatoire qui sont à la fois naturels et accessibles. Nous présentons une introduction pour une audience de mathématiciens, présentons de nouvelles connexions avec d’autres domaines (algèbres homologiques, ensembles partiellement ordonnés, polytopes), et résolvons certains problèmes. Parmi les résultats nouveaux, nous énumérons les adinkras de l’hypercube de dimension inférieure ou égale à 5, nous énumérons les $\textit{odd dashings}$ en toute dimension, et établissons une relation entre les $\textit{rankings}$ et le polynôme chromatique pour certains graphes.

Bacterial conjunctivitis is one of the most commonly encountered eye complications in medicine, particularly in developing nations. In Hadhramout Governorate-Yemen, there is no data about bacterial conjunctivitis among patients. The present study aimed to determine the prevalence rate of bacterial conjunctivitis among patients seeking hospitals in Hadhramout Governorate, Yemen. A total of 1722 eye swabs were collected from patients attending different Hadhramout hospitals over a period of April to December 2018. The isolation and identification of bacteria are performed using standard bacteriological procedures. In addition, structured questionnaires were used to gather data from patients. Out of 1722 eye swabs, 198 (11.49%) were positive for bacterial conjunctivitis, while 1524 (88.5%) were negative. The high prevalence rate of infection was among female participants and the age group between 31 and 40 years, at 15.25% and 29.29%, respectively. In addition, the prevalence of gram-positive bacteria was significantly greater among study patients than gram-negative bacteria (58.59% vs. 41.41%). The most predominant Gram-positive bacteria were Staphylococcus aureus (26.26%), followed by Streptococci pneumoniae (17.18%), Alpha-hemolytic Streptococci (8.08%), and Staphylococcus epidermidis (7.07%). Whereas the gram-negative bacteria were Pseudomonas aeruginosa (12.1%), followed by Moraxella catarrhalis (10.1%), Haemophilus influenza (7.07%), Klebsiella sp. (6.06%), Enterobacter agglomerans (4.04%), and Neisseria gonorrhoeae (2.02%). Additionally, the majority of study patients suffered from red eyes (100%), tearing eyes (93.93%), itching (90.9%), painful eyes (87.87%), purulent eyes (56.56%), and eye discharge (38.38%). The prevalence rate of bacterial conjunctivitis among patients in Hadhramout, Yemen, is relatively low compared with international investigations. Further investigation is required to assess and identify the antibiotic resistance to these agents that cause conjunctivitis.
