Depletion Sensitivity Partially Mediated the Relationship between Social Media Addiction and Academic Productivity Open
Aim/Purpose: The aim of this paper is to evaluate whether the use of social media by college students is linked with diminished academic productivity, and if so, why? Background: In prior research, social media use was inversely related to…

Trajectory tracking of unicycles under sampling and discrete-time Passivity-Based Control Open
The paper provides a new sampled-data and single-rate control law for trajectory tracking of unicycles under sampling. Assuming the reference generated by a continuoustime input sequence that is persistently exciting the design consists of…

Consensus and multi-consensus for discrete-time LTI systems Open
Existing consensus control algorithms for networked discrete-time linear systems have slow convergence to consensus trajectories due to limitations on the magnitude of the consensus gain. In this work we propose and analyze a new predictor…

Steering and Formation Control of Unicycles Under Single-Rate Sampling Open
In this paper, we propose a new digital feedback law for controlling unicycles in a sampled-data scenario. More in detail, two open problems are solved. First, assuming piecewise constant control and sampled-data measures of the state, we …

COVID-19 post-traumatic stress disorder: the role of ACEs, alexithymia, and attachment in the Italian population. Open
Emotional regulation and attachment have been shown to be risk factors for COVID-19 PTSD symptomatology. Focused intervention programs and emotional education can be useful tools for developing protective factors in the general population.

Exploring the Phase Diagram of the quantum one-dimensional ANNNI model Open
In this manuscript, we explore the intersection of QML and TN in the context of the one-dimensional ANNNI model with a transverse field. The study aims to concretely connect QML and TN by combining them in various stages of algorithm const…
