We show that Cutting Planes (CP) proofs are hard to find: Given an unsatisfiable formula F, It is -hard to find a CP refutation of F in time polynomial in the length of the shortest such refutation; and unless Gap-Hitting-Set admits a nontrivial algorithm, ...
Americans work more than Europeans. Using micro-data from the United States and 17 European countries, we document that women are typically the largest contributors to the cross-country differences in work hours. We also show that there is a negative relat ...
We prove an NP upper bound on a theory of integer-indexed integer-valued arrays that extends combi- natory array logic with an ordering relation on the index set and the ability to express sums of elements. We compare our fragment with seven other fragment ...
Group-based sparsity models are proven instrumental in linear regression problems for recovering signals from much fewer measurements than standard compressive sensing. The main promise of these models is the recovery of ``interpretable" signals along with ...

Synthesis from examples enables non-expert users to generate programs by specifying examples of their behavior. A domain-specific form of such synthesis has been recently deployed in a widely used spreadsheet software product. In this paper we contribute t ...
An insertion device (100; 100') for inserting a retinal prosthesis (200) into the eye of a patient comprises: a handle portion (1; 1') arranged to be grasped by a user of the insertion device (100; 100'), a cannula element (12; 12') arranged to be inserted ...

The concept of resilience has been applied within a wide spectrum of disciplines and has become increasingly relevant for interdisciplinary research. The interdisciplinary use of the concept can be linked to the fact that the conceptualization of resilienc ...

Prof. Laloui gave an interview with RTS about the status of geothermal energy in Switzerland in relation to its progression in other countries. Prof. Laloui discussed how the challenges associated with geothermal energy are primarily technical and how the ...
