The constraints of post-quantum classical gravity

open access: yesJournal of High Energy Physics, 2022
We study a class of theories in which space-time is treated classically, while interacting with quantum fields. These circumvent various no-go theorems and the pathologies of semi-classical gravity, by being linear in the density matrix and phase-space ...

Capacitive versus Faradaic Microelectrodes for Extracellular Stimulation: A Fully Coupled FEM–Hodgkin–Huxley Study of Thresholds and Current Redistribution

open access: yesAdvanced Electronic Materials, EarlyView.
A fully coupled FEM–HH model shows that ideally capacitive microelectrodes can achieve lower charge‐density thresholds than Faradaic contacts under current‐controlled stimulation. The advantage stems from the dynamics of surface current density on capacitive interfaces, which redirects current beneath adherent neurons.

Interior product, Lie derivative and Wilson line in the KBc subsector of open string field theory

open access: yesJournal of High Energy Physics, 2021
The open string field theory of Witten (SFT) has a close formal similarity with Chern-Simons theory in three dimensions. This similarity is due to the fact that the former theory has concepts corresponding to forms, exterior derivative, wedge product and

Mapping the Innovation DNA of Agribusiness Firms: A Multi‐Method Analysis of Strategic Capabilities and Performance

open access: yesAgribusiness, EarlyView.
ABSTRACT Innovation is essential for competitiveness in agribusiness facing dynamic environments. This study examines how market orientation, marketing, relational, and social capabilities influence innovation performance. Using data from 751 Spanish firms and a multi‐method approach that integrates Structural Equation Modeling (PLS‐SEM), Necessary ...

Five dimensional Chern–Simons gravity for the expanded (anti)-de Sitter gauge group $${\hbox {C}}_5$$ C5

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We study the Hamiltonian dynamics of a five-dimensional Chern–Simons theory for the gauge algebra $$C_5$$ C5 of Izaurieta, Rodriguez and Salgado, the so-called $$\hbox {S}_H$$ SH -expansão of the 5D (anti-)de Sitter algebra (a)ds, based on the cyclic ...

AI in chemical engineering: From promise to practice

open access: yesAIChE Journal, EarlyView.
Abstract Artificial intelligence (AI) in chemical engineering has moved from promise to practice: physics‐aware (gray‐box) models are gaining traction, reinforcement learning complements model predictive control (MPC), and generative AI powers documentation, digitization, and safety workflows.

The complexity of some families of cycle-related graphs

open access: yesJournal of Taibah University for Science, 2017
In this paper, we derive new formulas for the number of spanning trees of a specific family of graphs – gear graphs, flower graphs, sun graphs and sphere graphs – using techniques from linear algebra, Chebyshev polynomials and matrix theory.
