Space‐Time Smoothness and Parsimony in Covariance Functions

Mathematical Methods in the Applied Sciences, Volume 48, Issue 13, Page 13247-13259, September 2025.
ABSTRACT This paper challenges the trade off between computational efficiency and statistical accuracy within the framework of Gaussian space‐time processes. Under such a framework, the space‐time dependence is completely specified through the space‐time covariance function.

Skeleton‐Based Posture Recognition for Home Care From Virtual Unmanned Aerial Vehicle

Expert Systems, Volume 42, Issue 9, September 2025.
ABSTRACT This article presents a novel approach for real‐time posture recognition in monitoring scenarios, utilising a virtual camera simulated on a UAV within virtual environments. Leveraging the MediaPipe Pose library, key points of the body skeleton are extracted, focusing on a subset of 8 key points for computational efficiency.

Nanoarchitecture of CaV2.1 channels and GABAB receptors in the mouse hippocampus: Impact of APP/PS1 pathology

Brain Pathology, Volume 35, Issue 2, March 2025.
Nanoscale alteration of the molecular association between GABAB receptor and the CaV2.1 channel in actives zones the hippocampus of APP/PS1 mice. In wild‐type animals, the GABAB receptor and the CaV2.1 channel showed a high degree of co‐clustering in nanodomains (40 nm) of presynaptic active zones of axon terminals (at) establishing synapses with ...

Analog Sequential Hippocampal Memory Model for Trajectory Learning and Recalling: A Robustness Analysis Overview

Advanced Intelligent Systems, Volume 7, Issue 1, January 2025.
This work proposes a spike‐based bio‐inspired hippocampus sequential memory model that makes use of the benefits of analog computing and spiking neural networks: noise robustness, improved real‐time operation, and energy efficiency. For this reason, this model is implemented in the DYNAP‐SE hardware platform, applied to robotic navigation, and put in ...

Electrical impedance characterization and modelling of Ti‐Β implants

Journal of Biomedical Materials Research Part A, Volume 113, Issue 1, January 2025.
Abstract Commercially pure titanium (c.p. Ti) and Ti6Al4V alloys are the most widely used metallic biomaterials in the biomedical sector. However, their high rigidity and the controversial toxicity of their alloying elements often compromise their clinical success. The use of porous β‐Titanium alloys is proposed as a solution to these issues.

Mechanisms for the Spin‐State Switching of Strapped Ni‐Porphyrin Complexes Deposited on Metal Surfaces: Insights from Quantum Chemical Calculations

Small, Volume 21, Issue 2, January 15, 2025.
State‐of‐the‐art quantum chemistry methods are used to characterize the spin switching of strapped Ni porphyrin molecules deposited on Ag(111) surface. The LS and HS states are related by a vertical shift of the pyridine ligand, that modifies the Ni coordination number and promotes the spin transition. The voltage‐dependent spin switching is related to
