QSAR modelling for predicting adsorption of Sulfonylurea herbicides in agricultural volcanic ash-derived soils

Lizethly Cáceres-Jensen, Mauricio Foquett-Torres, Mauricio Molina-Roco, Jonathan Suazo-Hernández et autres

= 0.492, and 30/40 (75%) DAcoverage). The final QSAR interaction retained 24 descriptors, indicating that adsorption in VADS is governed by the interplay between herbicide ionisation/polarity and 3D electronic features as well as soil organo-mineral reactive domains (OM, C/N, Fe, Cu, S, …

Fundamental Work Scaling and Non‐Extensivity in Critical Engines

Bastián Castorene, Martin HvE Groves, Francisco J. Peña, Eugenio E. Vogel et autres

ABSTRACT We present a general analytical framework for critical two‐isothermal engines that emerge operationally from quasi‐static quantum Stirling cycles across ground‐state level crossings (GLCs) in the low‐temperature regime, where reversible heat exchange is governed by the structural entropy change while the internal …

Vacuum-selected timescales in driven Josephson systems

S. Allende, David Gálvez-Poblete

Abstract In this work, we demonstrate that the intrinsic timescale of a Josephson junction can be controlled through dynamical vacuum selection. By applying a Kapitza-like high-frequency drive to the system, the effective Josephson potential is reshaped, allowing for the stabilization of inphase …

Altermagnetic memcapacitors

Martin Latorre, Álvaro S. Núñez

We propose a spintronic memcapacitance effect based upon altermagnetic multiferroic materials. We identify the rare-earth vanadates RVO$_3$ as a concrete platform, with all key parameters tied to measured properties. Under an oscillating electric field, the resulting charge and spin currents trace pinched …

Electrically Switchable Spintronics in a Multiferroic Altermagnet

Martin Latorre, S. Allende, Álvaro S. Núñez

We introduce a minimal model of a two-dimensional lattice that, upon spontaneous symmetry breaking, simultaneously develops altermagnetic order, a finite electric polarization, and a spin-polarized transport response, all of which are controlled by an external electric field. By coupling a dimerized altermagnet …

Quantum approximate optimization algorithm with fixed number of parameters

Sebastian Saavedra-Pino, R. Bellido Quispe, G. Alvarado Barrios, E. Solano et autres

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 complexity, or circuit depth. By separating schedule …

Influence of Cu2O and Cu Engineered Nanoparticles on Soil Properties and Nutrient Availability

Jonathan Suazo-Hernández, Paz Cárcamo-Fincheira, Nicol Burgos, Antonieta Ruíz et autres

The increasing use of nano-agrochemical formulations in agricultural systems has intensified concerns regarding their impact on soil properties and nutrient dynamics. This study aimed to compare the effects of engineered copper (I) oxide nanoparticles (Cu2O-ENPs) and engineered copper nanoparticles (Cu-ENPs) on chemical …
