The regular part of transformation semigroups that preserve double direction equivalence relation

Let $T(X)$ be the full transformation semigroup on a set $X$ under the composition of functions. For any equivalence relation $E$ on $X$, define a subsemigroup $T_{E^*}(X)$ of $T(X)$ by\[T_{E^*}(X)=\{\alpha\in T(X):\text{for all}\ x,y\in X, (x,y)\in E\Leftrightarrow (x\alpha,y\al...

3D-Printed Poly(ε-Caprolactone)/CaCO3 Biocomposite Meshes for Bone Tissue Engineering: EnhancedMechanicalStrength and Cytocompatibility

Abstract Poly(ε-caprolactone) (PCL) is a biodegradable and biocompatible polyester widely used in biomedical scaffolds. However, its relatively low mechanical strength and limited cell adhesion properties remain major challenges for bone tissue engineering applications. This stud...

The Tyrolean Founder MLH1 Variant c.836T>G Causes Lynch Syndrome Due to a Leaky Splice Effect

The identification of a pathogenic variant (PV) in one of the mismatch repair (MMR) genes confirms the diagnosis of Lynch syndrome (LS). Hence, the correct classification of MMR gene variants is of utmost importance for appropriate counselling, surveillance, and treatment of LS p...

Health Behaviours and Experiences With Health Care Systems Among Thai Immigrants: A Scoping Review

The health behaviours and health care experiences of Thai immigrants are relevant in the context of growing global migration, as they navigate health care systems across their origin and host countries. While numerous studies have examined these issues, existing evidence remains...

Egg Drop Problems: They Are All They Are Cracked Up to Be!

We illustrate how to invite and excite students about research by exploring higher-dimensional generalizations of the classical egg drop problem, in which the goal is to locate a breaking point using the fewest number of trials. Beginning with the one-dimensional case, we prove t...

Surface-guided radiotherapy reduces residual setup errors in abdominal and pelvic radiotherapy

Abstract Introduction Achieving high setup accuracy is critical in modern radiotherapy, particularly with advanced techniques such as IMRT and VMAT. Surface-Guided Radiotherapy (SGRT) has been introduced to assist patient positioning and enhance setup reproducibility. This study...

Dosimetric comparison and delivery accuracy between DCAT and VMAT for stereotactic body radiotherapy using the deep inspiration breath-hold technique in liver cancer

Abstract Purpose: To compare plan quality and delivery accuracy between Volumetric Modulated Arc Therapy (VMAT) and 3-dimensional Dynamic Conformal Arc Therapy (DCAT) for liver stereotactic body radiotherapy (SBRT) using deep inspiration breath-hold (DIBH). Methods: Fifteen SBRT...

Mass Spectrometry-BasedProfiling of PersonalizedImmunopeptidomes in Thai Renal Cell Carcinoma

Abstract This study profiles the personalized immunopeptidomes of 13 Thai patients with renal cell carcinoma (RCC), addressing a critical knowledge gap in Southeast Asian populations characterized by distinct HLA allele distributions. We combined whole-exome sequencing (WES)–base...

Comparison of salivary fluoride levels following the application of rice-based and commercial fluoride gels: a randomized crossover trial

Salivary fluoride concentration is commonly used as an indicator of short-term fluoride exposure and clearance following topical fluoride application. Rice-based fluoride gels, formulated as rice-starch-HEC hybrid gels, may serve as alternative delivery systems; however, data reg...
