Adaptive Risk-Aware OpenStreetMap Planning for Scalable Radial Distribution Networks

A street-constrained distribution-network synthesis framework is evaluated using open geographic data, physical medium-voltage (MV) outage consequences, and benchmark electrical checks. A synthetic radial case study in Queens, New York, compares minimum-hop Dijkstra, minimum-span...

An Open Multi-Campus Dataset of Academic Service Requests Before and After Administrative Process Redesign

This paper presents an open, anonymized dataset of academic service requests collected before and after an administrative process redesign in a multi-campus university in Ecuador. The dataset was extracted from the Sistema Nacional Académico and covers two consecutive six-month p...

Isolation, Identification and Genomic Characterization of Carbamazepine-Tolerant Bacteria from Contaminated Aquatic Environments

Pharmaceutical contamination in aquatic environments has increased interest in microorganisms able to tolerating these compounds and the mechanisms underlying their tolerance. This study isolated and characterized carbamazepine (CBZ)-tolerant bacteria from contaminated waters of...

Antitumor-Relevant Evaluation of Liquid and Microencapsulated Lepidium meyenii and Bactris gasipaes Extracts Reveals Species- and Formulation-Dependent Activity

Lepidium meyenii and Bactris gasipaes are traditionally consumed plant foods with documented antioxidant and inflammation-related activities and emerging evidence of cancer-related biological effects. Accordingly, we compared the antitumor-relevant activity of these chemically di...

Three-dimensional optical vortices in nonlinear bessel waveguides

Abstract We explore the formation, stability, and propagation dynamics of light bullets carrying orbital angular momentum (vorticity) in Bessel-structured nonlinear graded-index waveguides. While these waves are prone to the collapse in uniform three-dimensional media, we demonst...

Two-Stage Conservative Management of Mandibular Unicystic Ameloblastoma with an Intraluminal Pattern: A Case Report

Intraluminal unicystic ameloblastoma is characterized by tumor proliferation confined to the cystic lumen, without invasion of the supporting connective tissue, a feature that has led some authors to regard it as particularly suited to conservative surgical treatment. Objective:...

Valorisation of Zingiber officinale hydrodistillation residual cake as a sustainable source of bioactive gingerols and shogaols: Quantification by validated HPLC-DAD and multi-spectroscopic characterization

Zingiber officinale Roscoe (ginger) hydrodistillation for essential oil production generates large quantities of residual cake, an underutilized by-product rich in non-volatile phenolics. This study characterized and quantified gingerols and shogaols in fresh Ecuadorian ginger rh...
