We investigate the problem of synthesizing distributionally robust control policies for stochastic systems under safety and reach-avoid specifications. Using a game-theoretical framework, we consider setting where probability distribution disturbance at each time step is selected from an ambiguity set defined by Wasserstein distance. The goal to synthesize policy that ensures satisfaction exceeds specified threshold any within set. First, both specifications, establish existence optimal...

Abstract Social contact surveys are an important tool to assess infection risks within populations, and the effect of non-pharmaceutical interventions on social behaviour during disease outbreaks, epidemics, pandemics. Numerous longitudinal were conducted COVID-19 era, however data analysis is plagued by survey fatigue, a phenomenon whereby average number contacts reported declines with repeat participations as participants’ engagement decreases over time. Using from German COVIMOD Study...

The Supplemental Nutrition Assistance Program (SNAP) provides millions of low-income Americans food benefits and other forms nutrition assistance. Evidence indicates that SNAP reduces insecurity. However, there is a concern the benefit may increase demand for less healthy foods more than healthier foods, thereby reducing overall nutritional quality participant's basket. This paper aims to examine association participation with food-at-home purchases households investigate potential...

This study introduces the development of hands-free control schemes for a riding ballbot, designed to allow riders including manual wheelchair users its movement through torso leaning and twisting. The hardware platform, Personal Unique Rolling Experience (PURE), utilizes ballbot drivetrain, dynamically stable mobile robot that uses ball as wheel provide omnidirectional maneuverability. To accommodate with varying motion functions, hanads-free scheme should be adjustable based on rider's...

Background: The global COVID-19 pandemic and response has focused on prevention, detection, response. Beyond morbidity mortality of those infected, pandemics carry secondary impacts, such as children orphaned or bereft their caregivers. Such often face adverse consequences, including poverty, abuse, delayed development, institutionalization. We provide estimates for the magnitude this problem resulting from describe need resource allocation.Methods: use fertility data to model rates...
