Model Theory of Homogeneous D-Sets

Estrada, Felipe · Goodrick, John

We explore several model-theoretic aspects of D-sets, which were studied in detail by Adeleke and Neumann. We characterize ultrahomogeneity in the class of colored D-sets and classify unbounded order-indiscernible sequences in such structures. We use these results to provide a characterization of distal colored D-sets...

SurgLaVi: Large-scale hierarchical dataset for surgical vision-language representation learning

Alejandra Perez · Chinedu Nwoye · Ramtin Raji Kermani · Omid Mohareri · y 1 más

Vision-language pre-training (VLP) offers unique advantages for surgery by aligning language with surgical videos, enabling workflow understanding and transfer across tasks without relying on expert-labeled datasets. However, progress in surgical VLP remains constrained by the limited scale, procedural diversity, seman...

Comparative Evaluation of Static-guided versus Freehand Endodontic Access in Single-rooted Permanent Teeth with Pulp Canal Calcification: A Randomized Clinical Trial

Afzal Ali · Anuja Ikhar · Ezgi Doğanay Yıldız · Hany Mohamed Aly Ahmed · y 5 más

The present study aimed to compare the use of conventional freehand access cavity preparation with the static-guided (SG) endodontic technique in terms of its ability to locate and negotiate root canals, iatrogenic errors (perforations), and the amount of tooth structure loss while treating single-rooted traumatized te...

Respiratory sarcopenia and prehabilitation in thoracic oncology: Diagnostic approaches and clinical implications

David Dávila-Dupont · Marisol Arroyo-Hernández · Jenny G. Turcott · Cittim B. Palomares-Palomares · y 6 más

Respiratory sarcopenia (RS) is increasingly considered in thoracic oncology because reduced strength and cough effectiveness may relate to perioperative pulmonary complications, symptom burden, and treatment tolerance. However, definitions, thresholds, and measurement protocols vary across studies, and the feasibility...

Ventricular free-wall rupture, ventricular pseudoaneurysm, and papillary muscle rupture complicating acute myocardial infarction

Roberto Lorusso · Matteo Matteucci · Daniele Ronco · Giulio Massimi · y 31 más

Abstract The prevalence of mechanical complications following acute myocardial infarction has steadily declined in recent years owing to advances in prompt coronary revascularization, and they now occur in <1% of acute myocardial infarction cases. Nevertheless, significant haemodynamic impairment may already be pres...

Clustering in hadrons and light nuclei from Lorentz boosted form factors

F.E. Rodríguez Barrera · N.G. Kelkar

The determination of nuclear charge radii is crucial for understanding the internal structure of nuclei and their fundamental interactions. A persistent discrepancy, not only in the measured proton charge radius but also in the light nucleus charge radius, between electron scattering and muonic spectroscopy has fueled...

The impact of supercritical CO₂ conditions on extracting antioxidant compounds from tangerine leaves (Citrus reticulata) for enhancing oxidative stability in soybean oil

Rodríguez-García, Mario E. · Martins Strieder, Monique · Domínguez-Rodríguez, Gloria · Moreno-Caballero, Michael · y 4 más

Tangerine leaves were valorized as a source of natural antioxidants for protecting soybean oil against lipid oxidation. Initial Soxhlet extracts obtained using hexane (Hexsingle bondS), ethyl acetate (EtOAc-S), and ethanol (EtOH-S) showed that the Hex-S extract provided the highest oxidative stability, highlighting the...
