We are building a series of custom casual games to support teaching and learning of introductory programming (CS1/2) concepts with a focus on ease of adoption. Our games are innovative twists on popular casual genres, and each game is designed explicitly for teaching specific programming concepts (e.g., conditionals, arrays). Based on these games, faculty can explain and students can explore CS...

In recent years, graphical user interfaces have become almost ubiquitous in form of notebooks, smartphones and tablets. These systems normally force the user to attend to an often very specific and narrow screen and thus squeeze the information through a chokepoint. This ties the users’ attention to the device and affects other activities and social interaction. In this paper we introduce Blend...

Quantum memory effects can be induced even when the (time-dependent) dynamical degrees of freedom associated to environment are not affected at all by open system during their joint coupled evolution. In this paper, based on a completely positive bipartite representation system-environment dynamics, we found more general interactions that lead class quantum non-Markovian ``casual bystander'' en...

We distinguish between the notions of asymptotic causality and infrared for gravitational effective field theories, show that latter gives constraints consistent with positivity bounds. re-explore scattering waves in a spherically symmetric background EFT gravity $D\ge 5$, which leading-order correction to Einstein is determined by Gauss-Bonnet operator. reproduce known result truncated theory ...
