Relating Edelman-Greene insertion to the Little map
Authors: Hamaker Zachary , Young Benjamin
Published: January 2024

The Little map and the Edelman-Greene insertion algorithm, a generalization of the Robinson-Schensted correspondence, are both used for enumerating the reduced decompositions of an element of the symmetric group. We show the Little map factors through Edelman-Greene insertion and establish new results about each map as a consequence. In particular, we resolve some conjectures of Lam and Little.

La correspondance de Little et l’algorithme d’Edelman-Greene généralisant la correspondance de Robinson-Schensted sont utilisés pour l’énumération des décompositions réduites associées aux éléments du groupe symétrique. Nous démontrons que la correspondance de Little peut être réduite à celle d’Edelman-Greene. En particulier, nous obtenons de nouvelle réponses à quelques conjectures de Lam et Little

Authors: Berg Chris , Bergeron Nantel , Saliola Franco , Serrano Luis , Zabrocki Mike
Published: January 2024

We introduce a new basis of the non-commutative symmetric functions whose elements have Schur functions as their commutative images. Dually, we build a basis of the quasi-symmetric functions which expand positively in the fundamental quasi-symmetric functions and decompose Schur functions according to a signed combinatorial formula.

Nous introduisons une nouvelle base des fonctions syméetriques non commutatives dont les images commutatives sont des fonctions de Schur. Nous construisons la base duale des fonctions quasi-symétriques qui s’expriment de façon positive en fonction de la base fondamentale et décomposent les fonctions de Schur.

Authors: Loehr Nicolas , Serrano Luis , Warrington Gregory
Published: January 2024

We introduce explicit combinatorial interpretations for the coefficients in some of the transition matrices relating to skew Hall-Littlewood polynomials $P_{\lambda / \mu}(x;t)$ and Hivert's quasisymmetric Hall-Littlewood polynomials $G_{\gamma}(x;t)$. More specifically, we provide the following: 1. $G_{\gamma}$-expansions of the $P_{\lambda}$, the monomial quasisymmetric functions, and Gessel's fundamental quasisymmetric functions $F_{\alpha}$, and 2. an expansion of the $P_{\lambda / \mu}$ in terms of the $F_{\alpha}$. The $F_{\alpha}$ expansion of the $P_{\lambda / \mu}$ is facilitated by introducing the set of $\textit{starred tableaux}$. In the full version of the article we also provide $G_{\gamma}$-expansions of the quasisymmetric Schur functions and the peak quasisymmetric functions of Stembridge.

Plus spécifiquement, nous donnons les suivants: 1. $G_{\gamma}$-expansions pour le $P_{\lambda}$, les fonctions monomiales quasi-symétriques et les fonctions fondamentales quasi-symétriques de Gessel’s $F_{\alpha}$ et 2. une expansion des $P_{\lambda / \mu}$ en termes des $F_{\alpha}$. L’expansion des $P_{\lambda / \mu}$ en termes des $F_{\alpha}$ est facilitée grâce a l’introduction de l’ensemble de $\textit{tableaux étoilés}$. Dans la version complète de cette article, nous donnons aussi $G_{\gamma}$-expansions pour les fonctions quasi-symétriques de Schur et les fonctions quasi-symétriques de pic de Stembridge.

Published: January 2024

Weighted hypertrees have been used by C. Jensen, J. McCammond, and J. Meier to compute some Euler characteristics in group theory. We link them to decorated hypertrees and 2-coloured rooted trees. After the enumeration of pointed and non-pointed types of decorated hypertrees, we compute the character for the action of the symmetric group on these hypertrees.

Des hyperarbres pondérés ont été utilisés en théorie des groupes, par C. Jensen, J. McCammond et J. Meier pour calculer des caractéristiques d’Euler. Nous relions ces hyperarbres pondérés à des hyperarbres décorés, puis à des arbres enracinés 2-colorés. Après énumération des hyperarbres décorés pointés et non pointés, nous déterminons le caractère de l’action du groupe symétrique sur les hyperarbres.
Variation in Pb and Zn concentrations in different species of trees and shrubs and their organs depending on traffic density
Authors: Guney Deniz , Koc Ismail , Isinkaralar Kaan , Erdem Ramazan
Published: January 2024

Global population growth and increasing urban population density together are responsible for many disruptions such as environmental pollution, especially air one. Trace metals are of specific prominence as air pollutants because they are conservative pollutants. They tend to accumulate biologically; some have poisonous or carcinogenic effects, even at small concentrations. Among toxic trace metals, lead (Pb) and zinc (Zn) can be harmful to human health in certain quantities. These trace metals were included in primary pollutant lists of the Agency for Toxic Substances and Disease Registry. Therefore, determining these trace metal concentrations in the air and monitoring the differences is very important for determining the risky districts and the level of risk. Biomonitors are the most important indicators of differences in trace metal concentrations in the atmosphere. The plants chosen as biomonitors intake several of the trace metals from the soil and/or the air into their bodies and determining the level of this accumulation might provide insight into the trace metal pollution of the atmosphere and soil. The present study aims to determine the variations of Pb and Zn concentrations in various landscaping plants growing in different districts of Kastamonu (Türkiye) depending on tree species, organs and traffic density. It was found that unwashed leaves of Acer negundo L. can be suggested as a good biomonitor for the presence of both analysed trace metals.

Published: January 2024

The rare Cu-Zn sulphate, ktenasite, was found in the association with schulenbergite, serpierite, gypsum and brochantite at abandoned stope of the Modrá štola adit, the ore deposit Zlaté Hory - East, Czech Republic. Ktenasite occurs there as two different (color, morphology) types, the first is olive green to dark green columnar crystals up to 4 mm in length which forms radially arranged groups or rich crystalline coatings. The second type is represented by blue to greenish blue crystalline coatings or hemispherical or fan-shaped aggregates formed by thin tabular crystals. The X-ray powder diffraction data, Raman spectra and chemical composition of both types are almost identical. Ktenasite is monoclinic, space group P21/c, the unit-cell parameters refined from X-ray powder diffraction data are: a 5.610(2), b 6.123(2), c 23.827(9) Å, β 95.27(3)o and V 815.0(4) Å3. Its chemical analyses correspond to the empirical formula Zn1.00(Cu3.13Zn0.96Mg0.07Al0.01)Σ4.17(SO4)1.98(PO4)0.01(SiO4)0.01(OH)6.32·6H2O. Schulenbergite most often occurs only as an admixture in blue-green crystalline aggregates of ktenasite, sometimes together with serpierite. More rarely, its blue tabular crystals with a pearly luster up to 0.4 mm in size were also observed. Schulenbergite is trigonal, space group R-3, the unit-cell parameters refined from X-ray powder diffraction data are: a 8.187(3), c 7.012(4) Å and V 410.5(3) Å3. Its chemical analyses correspond to the empirical formula (Cu4.96Zn2.34)7.30(SO4)1.92(SiO4)0.05(PO4)0.02 (OH)10.47·6H2O. Serpierite is relatively abundant in the studied mineral association, usually forms light blue fine crystalline coatings, its fan-shaped aggregates up to 4 mm in size formed by elongated tabular crystals have also been found more rarely. Its chemical analyses correspond to the empirical formula (Ca1.14Mn0.03Mg0.02)Σ1.19(Cu3.08Zn0.73)Σ3.81(SO4)1.99 (PO4)0.02(OH)5.97·3H2O. Abundant brochantite forms bright green crystalline coatings and tiny dark green to black-green crystals. Its chemical analyses correspond to the empirical formula (Cu3.80Zn0.17Al0.02)Σ3.99(SO4)0.99(PO4)0.01(OH)6.00. The origin of studied mineral association is connected with sub-recent weathering of primary sulphides (pyrite, pyrrhotite, sphalerite and chalcopyrite) in the conditions of abandoned mine space.

FRENECTOMY ON MAXILLARY LABIAL FRENULUM PENETRATING PAPILLA TYPE BY CONVENTIONAL SURGICAL TECHNIQUES: A CASE REPORT
Authors: Syahriel Dwis , Syahrul Dwis , Agraha Arya Kusuma , Putri Asri Riany
Published: January 2024

Introduction: The frenulum is a fold of mucosa that attaches the lips and cheeks to the alveolar mucosa, gingiva, and underlying periosteum. If the attachment is too high and thick to approach the gingival margin (papilla penetrating type) it causes a central diastema on the upper incisor or recurrence after orthodontic treatment, besides causing oral hygiene problems and gingival recession as well as denture stability. An abnormal frenulum should be removed by frenectomy.
History and Clinical Finding: An 18-year-old female patient with a tall and thick maxillary labial frenulum as a cause of central diastema on teeth 11, 21. The patient had been treated with removable orthodontics starting 2 years ago. Since 4-6 months ago the diastema has relapse. The maxillary labial frenulum appears to be attached to the incisive papilla (penetration of the papillae). The Blanch test shows movement of the interdental papillae and blanching (ischemia) of the incisor papillae.
Case Management: Frenectomy using a scalpel until all the papillae and fibrous fibers are removed. Control 14 days postoperative, the wound was healed. During the blanching test, there was no movement of the papillae and the color was normally.
Discussions: The high maxillary labial frenulum causes the two central incisors to erupt far apart. Orthodontic treatment  must be accompanied by removal of the etiological factor by frenectomy for the treatment to be successful.
Conclusions: Penetrating papilla type frenectomy of the maxillary labial frenulum with the conventional technique of using a scalpel effectively eliminates the causes of central diastema.

BPJS Employment is a state program that aims to provide guaranteed social protection for all Indonesian workers. Death Benefit (JKM) is a social security program implemented nationally based on social insurance principles with the aim of providing death benefits paid to the heirs of participants who die. Fulfilling worldly needs is an obligation. However, fulfilling the world's needs to achieve these needs can be done by protecting yourself, but still following Islamic law. This research aims to find out how the implementation of providing death insurance for the heirs of BPJS Employment Medan Branch according to the Sharia Insurance Perspective. This research uses a qualitative descriptive analysis method. Collecting research data through observation and interviews. The informants for this research are the Head of BPJS Employment Services, Medan Branch Office and the beneficiaries of the Death Insurance Program. The results of the research show that the implementation of providing death insurance to heirs has not been effectively implemented because the death compensation funds to heirs are late so that the death compensation cannot be felt during the death procession starting from the burial of the body to the prayer for the souls from the 7th day, even 40th day soul prayer. This is due to the heirs' lack of understanding in implementing the death insurance program and the application or processing of death insurance application documents requires too many requirements so that getting the death insurance benefits takes a long time. The non-payment of participants' death insurance claims for months by BPJS Employment has three strong indications of maladministration, namely protracted delays, non-compliance and unprofessionalism. Maladministration is behavior or acts against the law and ethics in the public service administration process. The forms of maladministration are procedural deviations, discriminatory actions, abuse of authority, including negligence or neglect of legal obligations, requests for rewards, and others. In the implementation of providing death insurance to heirs by BPJS Employment Medan Branch, it is not in accordance with sharia insurance principles, there is the occurrence of chance which has an impact on the element of maysir (gambling), there is an element of usury fadhl (excess between what is received and what is paid), including fines for lateness.

The current study aims to investigate the effect of the Vitex Angus-cactus leaves extract on body weight, haematological and biochemical of chicken. The chicken was divided into four groups. The first group was given orally 5mg, the second 10 mg, the third 15 mg dose of Vitex extract every day for a period of 30 days and the fourth group served as a control group. The result revealed an increase in the body weight of treated chicken by 11.76 % at a 15 mg dose of Vitex extract compared to the control group. Non-significant increase was in haemoglobin (Hb) amount and the total erythrocyte (RBC) count, while white blood cells (WBC) decreased significantly in treated chicken. The plasma aspartate aminotranseferase (AST) was decreased significantly at all doses of vitex extract and alanine aminotransferase (ALT) increased by 41% only at 15 mg dose of extract. The plasma urea level does not changed by treatment in comparison to the control group. The total serum testosterone was not detectable by treatment of 10 mg and 15 mg doses of Vitex extract. In conclusion, the treatment of chicken with some dose of Vitex leaf extract can improve their body weight and some haematological and biochemical parameters.

Early pregnancy failure is a medical complication and major health problem across the globe. The aim of this study is to compare manual vacuum aspiration (MVA) and dilatation and curettage (D&C) for first trimester abortion, in terms of the efficiency of eliminating retain product of conceptus, frequency of complications, duration of the procedure, and duration of patients' hospitalization. This is a prospective comparative descriptive study performed at Al-Sadaqa Teaching Hospital. Over a period from 1st Jan 2020 to 31st December 2020, a total of 143 women, these patients either MVA group (n=72) or D&C group (n=71). Presented with spontaneous abortion and gestational age less than 12 weeks, patent cervix, and no signs of septic abortion, hemoglobin ≥9 g/dl and no bleeding disorder. Data was collected on prescribed questionnaire. The total number of abortion 637 in compare to 259 (40.7%) patient with first trimester abortion,  143 patients  was included in this study, MVA group (n =72) and D&C group (n=71).  The distribution in respect to the age, parity & gestational age was similar in both groups.  The mean duration of procedure was significantly higher (P<0.05) in D&C group compared to MVA group. The duration of hospital stay was significantly lower (P<0.05) in MVA group compared to D&C group. MVA group showed the least incidence of complications regarding the amount of blood loss, and cervical laceration. Complete evacuation was achieved in 95.8% in MVA vs. 98.6% in D&C group with no statically significant (P=0.304). MVA is as effective as popular dilatation and curettage for treatment of early pregnancy failure while it need less time consuming, requires a shorter hospital stay and subsequently costs less. It does not require general anesthesia and complication rate is less than dilatation and curettage. So it can be easily accessible to the woman of both rural and urban societies belonging to any socioeconomic strata especially where high tech equipment and power supply are not available.

Failure of root canal treatment (RCT) occurs when endodontic treatment falls short of standard clinical guidelines. An improper mechanical debridement (shaping and cleaning), persistence of bacteria inside the canals and apex, poor obturation quality, coronal leakage, and experience of dentists all probably influence the RCT success or failure. Although there is substantial success of RCT, failures take place in many cases, which usually could be related to the previously mentioned factors. So, it’s considerably imperative to stop the foremost potential factors that cause RCT failure. This paper reviews how to increase the success rate of the RCT.

A REVIEW OF DIY'S DECENTRALIZATION OF THE URBAN SPRAWL PHENOMENON IN THE YOGYAKARTA METROPOLITAN AREA (KARTAMANTUL)
Authors: Alvianti Vivian , Fathurrahman Fathurrahman
Published: January 2024

Decentralization in Indonesia has led to a shift in responsibilities from the central government to the regions. This has been observed in the distribution of jobs and population across metropolitan areas, such as in the Yogyakarta Metropolitan Area (Kartamantul). Kartamantul is a secondary metropolitan area in Indonesia where local governments have taken the initiative to jointly form a Joint Secretariat. The development of Kartamantul has expanded into the peripheral areas, as evidenced by changes in land use. This article examines the impact of decentralization by the Government of the Special Region of Yogyakarta on the phenomenon of urban sprawl in the Kartamantul Region. The analytical method used is descriptive analysis, with secondary data collection from previous research on decentralization and urban sprawl in Yogyakarta. The results of the analysis identify the characteristics of urban sprawl in Kartamantul based on three aspects: land use change, population growth, and economic growth. By 2017, there had been changes in non-built-up land use in the peri-urban areas of Yogyakarta, accompanied by population growth and economic expansion. The Joint Secretariat of Kartamantul has come up with solutions to address the urban sprawl phenomenon, such as the addition of Trans-Jogja routes reaching Bantul and Sleman regencies, as well as collaborative management of the Piyungan Landfill and Sewon WWTP. The conclusion of this research is that cooperation among regional governments through the Joint Secretariat of Kartamantul is an effective grassroots initiative. However, there is a need for the Joint Secretariat to be involved in spatial planning due to the complex development challenges in Kartamantul.
