Cross platform mobile application development using web technologies has traveled a long way since its inception back in 2008-2009 [1]. Frameworks such as Apache Cordova/Phonegap [2] or Appcelerator [3] enabled web developers to reuse their exiting development skills to build applications for a wide variety of mobile platforms and opened up app development to a massive community. Since then man...

We investigate a game played on a hypergraph H = (V,E) by two players, Balancer and Unbalancer. They select one element of the vertex set V alternately until all vertices are selected. Balancer wins if at the end of the game all edges e ∈ E are roughly equally distributed between the two players. We give a polynomial time ∗Research supported in part by a USA-Israel BSF grant, by the Israel Scie...

Ultrathin devices are rapidly developing for skin-compatible medical applications and wearable electronics. Powering skin-interfaced electronics requires thin lightweight energy storage devices, where solution-processing enables scalable fabrication. To attain such a sequential deposition is employed to achieve all spray-coated symmetric microsupercapacitors (?SCs) on ultrathin parylene C subst...
