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.

Sobolev estimates and inverse Hölder estimates on a class of non-divergence variation-inequality problem arising in American option pricing

open access: yesElectronic Research Archive
We studied the Sobolev estimates and inverse Hölder estimates for a class of variational inequality problems involving divergence-type parabolic operator structures.

On the optimal control for variational inequalities [PDF]

open access: yesJournal of Optimization Theory and Applications, 1976
We prove an existence theorem for the optimal control of variational inequalities governed by a pseudomonotone operator: the cost is assumed to be quadratic. Then, we give an extension of the theorem to more general costs (assuming the operator to be monotone); we also give a result on a perturbation problem.

“I never realized how hard recovery is.” A quasi‐experimental evaluation of a youth participatory action research project for opioid prevention

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract Youth participatory action research (YPAR) has been effectively used for substance use prevention. Yet, YPAR has not been evaluated for opioids, which negatively impact individuals and communities across the United States. The current study evaluated an opioid‐focused YPAR project.

Algorithms for Solving the Variational Inequality Problem over the Triple Hierarchical Problem

open access: yesAbstract and Applied Analysis, 2012
This paper discusses the monotone variational inequality over the solution set of the variational inequality problem and the fixed point set of a nonexpansive mapping.

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.

Navigating an STI diagnosis: The role of social support, intergenerational learning, and transformative growth among Black women

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract Black women face a myriad of challenges that heighten their susceptibility to sexually transmitted infections (STIs), resulting in a disproportionate impact of STIs among this population. Yet, there is a lack of research that explores how women navigate these diagnoses with resilience.

Mixed variational inequalities

open access: yesApplied Mathematics Letters, 1990
AbstractIn this paper, we use the fixed-point technique to prove the existence of a unique solution of a new unified and general class of variational inequalities. Several special cases are also discussed.

Parents' WhatsApp coping resources in the context of ongoing political conflicts: An ecological exploration

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract Mobile technologies have become significant resources for crisis communication and social support in recent years. However, despite empirical evidence pointing to the centrality of these technologies for parenthood in everyday life, it is yet unknown how parents' coping resources play a role in the digital environment.
