Basal Cell Carcinoma Research Landscape Overview via Latent Dirichlet Allocation and HJ-Biplot Analysis

Karime Montes-Escobar · Javier de La Hoz-Maestre · Humberto Llinás-Solano · Carlos Alfredo Salas-Macias · y 3 más

Background: Basal cell carcinoma (BCC) of the skin is the most common cancer in humans, and its incidence rises annually. Despite its low death rate, BCC causes significant morbidity because of its destructive nature to local tissues. The aim of this study was to review the state of the BCC research landscape using dat...

Molecular testing, first-line treatment patterns, and survival in metastatic Colombian non–small cell lung cancer: the RECAPC multicenter registry

Brugés, Ricardo · Ramos, Pedro · Lombana, Milton · Osma, Anderson · y 12 más

Background Molecular profiling and programmed death-ligand 1 (PD-L1) status guide first-line treatment selection in metastatic non–small cell lung cancer, yet real-world testing, treatment delivery, and documentation vary across health systems. We described molecular testing documentation, first-line treatment patterns...

Paediatric long QT syndrome: clinical outcomes and therapy in the Spanish National Registry

Francesca Perin · Antonio J Cartón · Francisco Jose Bermúdez-Jiménez · Bárbara C Fernández-Barrio · y 31 más

Abstract Background and Aims Congenital long QT syndrome (LQTS) is a heterogeneous disorder in which genotype and QTc duration modulate the risk of major arrhythmic events (MAEs), but contemporary paediatric outcome data remain limited. This study aimed to characterize clinical features, management strategies, and pred...

Chemo-Diversity and Secondary Metabolite Content in Corticolous Crustose Lichens (Fam. Arthoniaceae, Graphidaceae, Pyrenulaceae) from Remnants of Colombian Tropical Dry Forests

Pierine España-Puccini · Amner Muñoz-Acevedo · Natalia A. Llanos-López · Marc Stadler · y 3 más

Colombia ranks third among South American countries in terms of fungal diversity (including lichens); however, the lichen diversity of tropical dry forest ecosystems, particularly those in the Caribbean region, remains relatively understudied. The typical lichens found in tropical dry forest are crustose/corticolous mi...

Counting with Two-Level Polynomials

Bogart, Tristram · Woods, Kevin

We examine combinatorial counting functions with two parameters, $n$ and $q$. For fixed $q$, these functions are (quasi-)polynomial in $n$. As $q$ varies, the degree of this polynomial is itself polynomial in $q$, as are the leading coefficients. We carefully define these two-level polynomials, lay out their basic alge...

Conservative plausibility-filtered SMOTE for credit card fraud detection under extreme class imbalance

Becerra-Suarez, Fray L. · Arones-Perez, Paolo P. · Zamora-Del-Aguila, Frederik F. · Forero, Manuel G.

Detecting credit card fraud is a complex tabular learning problem due to the underrepresentation of fraudulent events, extreme class imbalance, and scattered minority areas. To address this limitation, a conservative minority synthesis strategy is proposed, combining the removal of minority outliers, synthetic data gen...

MARÍN GARCÍA, EDWARD · Niño, Juan Andrés · Gutiérrez Duran, José Alfredo

The consolidated World Intellectual Property Organization (WIPO) database contains 90,167 greenhouse-related patent records published between 1975 and 2025 across 75 countries or jurisdictions. Each record includes the publication date, geographical origin, patent title, and International Patent Classification (IPC) co...

Day-ahead active and reactive power scheduling of wind turbines and battery energy storage systems for power loss and CO2 emission reduction in AC microgrids

Daniel Sanin-Villa · Héctor Pinto Vega · Carlos R. Baier · Walter Gil-González · y 1 más

This paper proposes a day-ahead scheduling framework to analyze and optimize the impact of the coordinated active and reactive power management of wind turbines (WTs) and battery energy storage systems (BESSs) on the energy losses and CO 2 emissions of AC microgrids (MGs). Within this framework, the BESS plays a centra...
