Centimeter‐Scale Magneto‐Reconfigurable Parallel Robots: A Grassmann Line Geometry Synthesis Framework for Multitask Adaptation Using Magneto‐Connected Part Library

open access: yesAdvanced Intelligent Systems, EarlyView.
A low‐cost, Lego‐like magneto‐connected part library is proposed, capable of rapidly assembling, disassembling, and reassembling compact, centimeter‐scale parallel robots with various motion types, balancing structural rigidity and reconfiguration agility.

Concentration Inequalities for Randomly Permuted Sums [PDF]

open access: yes, 2019
Initially motivated by the study of the non-asymptotic properties of non-parametric tests based on permutation methods, concentration inequalities for uniformly permuted sums have been largely studied in the literature. Recently, Delyon et al. proved a new Bernstein-type concentration inequality based on martingale theory.

A Soft Wearable Robot for Vertical Jump Enhancement via a Pneumatic Energy‐Storing Propulsion Actuator and Triarticular Kinetic‐Chained Structure

open access: yesAdvanced Intelligent Systems, EarlyView.
The Jump‐Enhancing Textile Suit integrates the Pneumatic Energy‐Storing Propulsion Actuator (PESPA) and the Triarticular Kinetic‐Chained Structure (TKiCS). PESPA stores elastic energy under pneumatic pressure and releases it during the propulsive phase to augment movement.

A criterion for Talagrand's quadratic transportation cost inequality

open access: yes, 2003
We show that the quadratic transportation cost inequality $T_2$ is equivalent to both a Poincar\'e inequality and a strong form of the Gaussian concentration property.

Exploring the link between the risk of violent injury in adolescents and historic redlining practices

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract Violent injuries tend to cluster together geospatially. The discriminatory housing practice of redlining undertaken by the United States federal government in the 1930s has been repeatedly linked with various contemporary community‐level disparities.

Facilitators and barriers to neighborhood social integration

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract Social isolation has reached concerning rates, particularly in the wake of the COVID‐19 pandemic. Social integration is critical to combatting social isolation and loneliness by promoting a sense of community and belonging. Yet, most existing research centers on fostering close personal relationships within family and friend networks.
