Beyond the menu: assessing the environmental and social impact of institutional meals
Purpose This study aims to assess institutional meals’ environmental and social sustainability by analyzing 50 dishes served at a public university cafeteria in Chile. It seeks to identify inefficiencies and propose practical improvements by considering factors such as carbon foo...

This study examined the evolution of action frequencies associated with victory in UFC bouts across three distinct eras (2003–2004, 2013–2014, and 2023–2024). A total of 1722 fights were analyzed: Early Era (2003–2004; n = 77), Transition Era (2013–2014; n = 813), and Modern Era...

About a Ball Removal Process on Bins
We consider a basic balls-and-bins question in which you have to distribute n balls into k bins. Then, round by round, a ball is removed from a nonempty bin chosen uniformly at random. The process ends when a single nonempty bin remains. The goal is to minimize the expected numbe...

Transient cartilages and interdigital vasculature organization in the embryonic duck foot
Abstract The evolution of webbed limbs represents a recurrent adaptation to aquatic life in tetrapods, facilitated by the dynamics of embryonic digit development. Digits form at the distal tip of the limb bud as cartilage condensations surrounded by mesenchymal cells, a process d...

Dust Substructures and Line Perturbations driven by a Forming Planet in J16120
Abstract Hints of planet formation have been independently reported within the gap of the disc around 2MASS J16120668-301027 from millimetre continuum, infrared, and Hα observations. In this work, we present new evidence for ongoing planet formation based on Atacama Large Millime...

Development and validation of a time use questionnaire for women in family farming
Abstract This study develops and validates the Time‑Use Questionnaire for Women in Family Farming (TUQ‑FF), a context‑specific instrument designed to measure productive, domestic, caregiving, and social‑participation activities among rural women in Chile. Drawing on international...

Abstract We report the oldest record of a capybara (Caviidae: Hydrochoerinae) in Chile, dated at ca. 8.8 Ma, which along with paleobotanical proxy records, indicates a markedly wetter late Miocene Atacama Desert. Today hyperarid, the Atacama contrasts sharply with the semiaquatic...

Magneto-optical detection of spin-orbit torque vector with first-order Kerr effects
Abstract We present a magneto-optical method for quantifying both components of the spin-orbit torque (SOT) effective field vector h_SO in magnetic thin films that, unlike previous complete-vector magneto-optical schemes relying on quadratic Kerr effects for at least one componen...

Neurodegenerative diseases remain a major therapeutic challenge, with oxidative stress playing a central role in central and peripheral immune system dysfunction that leads to neuronal loss. Natural products from extreme environments represent an underexplored source of neuroprot...

We present a theoretical investigation of resonant charge transfer in low-energy Li+ ions backscattered from a MoS2 surface, focusing on the influence of excited projectile states. Using a time-dependent Anderson model in the infinite-U limit, we evaluate the individual contribut...

Hydrodynamic Features of Two-Phase Oil–Gas Flow in Pipelines
The results of the experiments on the transport process of fluid flow through a pipeline under temperature gradient conditions between the internal and external environments, and on continuous gas generation at the contact boundary of the transported media, are presented in this...

Quantum approximate optimization algorithm with fixed number of parameters
We introduce a novel quantum optimization paradigm: the Fixed-Parameter-Count Quantum Approximate Optimization Algorithm (FPC-QAOA). It is a scalable variational framework that maintains a constant number of trainable parameters regardless of the number of qubits, Hamiltonian com...
