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

Posted by January 4, 2021Tokyo

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 January 2, 2021Stanford

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 January 1, 2021Stanford

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 […]

Non-Hermitian Dynamics Mimicked by a Hermitian Nonlinear System

Posted by klaurent January 1, 2021Cornell

Kavli Affiliate: Jeffrey Moses | First 5 Authors: Noah Flemens, Nicolas Swenson, Jeffrey Moses, , | Summary: We illustrate that a Hermitian nonlinear optical system consisting of hybridized parametric amplification and second harmonic generation mimics non-Hermitian evolution dynamics. Oscillation damping, evolution to a static steady state, and exceptional points arise from the use of second […]

QubiC: An open source FPGA-based control and measurement system for superconducting quantum information processors

Posted by klaurent December 31, 2020Berkeley

Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Yilun Xu, Gang Huang, Jan Balewski, Ravi Naik, Alexis Morvan | Summary: As quantum information processors grow in quantum bit (qubit) count and functionality, the control and measurement system becomes a limiting factor to large scale extensibility. To tackle this challenge and keep pace with rapidly evolving […]

Abelian envelopes of exact categories and highest weight categories

Posted by klaurent December 31, 2020Tokyo

Kavli Affiliate: Alexey Bondal | First 5 Authors: Agnieszka Bodzenta, Alexey Bondal, , , | Summary: We define admissible and weakly admissible subcategories in exact categories and prove that the former induce semi-orthogonal decompositions on the derived categories. We develop the theory of thin exact categories, an exact-category analogue of triangulated categories generated by exceptional […]
