Distributionally robust second-order stochastic dominance constrained optimization with Wasserstein ball

Posted by Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Yu Mei, Jia Liu, Zhiping Chen, , | Summary: We consider a distributionally robust second-order stochastic dominance constrained optimization problem. We require the dominance constraints hold with respect to all probability distributions in a Wasserstein ball centered at the empirical distribution. We adopt the sample approximation approach […]

Polarized radiation and the Emergence of Biological Homochirality on Earth and Beyond

Posted by klaurent Stanford

Kavli Affiliate: Roger D. Blandford | First 5 Authors: Noemie Globus, Anatoli Fedynitch, Roger D. Blandford, , | Summary: It has been proposed that spin-polarized cosmic radiation can induce asymmetric changes in helical biopolymers that may account for the emergence of biological homochirality. The parity violation in the weak interaction has direct consequences on the […]

PHOENIX: Device-Centric Cellular Network Protocol Monitoring using Runtime Verification

Posted by klaurent Stanford

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Mitziu Echeverria, Zeeshan Ahmed, Bincheng Wang, M. Fareed Arif, Syed Rafiul Hussain | Summary: End-user-devices in the current cellular ecosystem are prone to many different vulnerabilities across different generations and protocol layers. Fixing these vulnerabilities retrospectively can be expensive, challenging, or just infeasible. A pragmatic approach for […]
