K*(892)0 and K̅ *(892)0 production in central Pb + Pb, Si + Si, C + C, and inelastic p + p collisions at 158A GeV
(American Physical Society, 2011-12)Production of the K∗(892)0 and K∗(892)0 resonances was studied via their K+π− and K−π+ decay modes in central Pb + Pb, Si + Si, C + C, and inelastic p + p collisions at 158A GeV(√sNN = 17.3 GeV) with the NA49 detector at ... -
k-Cut: A Simple Approximately-Uniform Method for Sampling Ballots in Post-election Audits
(Springer International Publishing, 2018-11)© 2020, International Financial Cryptography Association. We present an approximate sampling framework and discuss how risk-limiting audits can compensate for these approximations, while maintaining their “risk-limiting” ... -

K-median clustering, model-based compressive sensing, and sparse recovery for earth mover distance
(Association for Computing Machinery (ACM), 2011-06)We initiate the study of sparse recovery problems under the Earth-Mover Distance (EMD). Specifically, we design a distribution over m x n matrices A such that for any x, given Ax, we can recover a k-sparse approximation ... -
K-ras Mutation Targeted to Gastric Tissue Progenitor Cells Results in Chronic Inflammation, an Altered Microenvironment, and Progression to Intraepithelial
(American Association for Cancer Research, 2010-11)Chronic infectious diseases, such as Helicobacter pylori infection, can promote cancer in a large part through induction of chronic inflammation. Oncogenic K-ras mutation in epithelial cells activates inflammatory pathways, ... -
K-robots clustering of moving sensors using coresets
(Institute of Electrical and Electronics Engineers (IEEE), 2013-05)We present an approach to position k servers (e.g. mobile robots) to provide a service to n independently moving clients; for example, in mobile ad-hoc networking applications where inter-agent distances need to be minimized, ... -
The K-server problem via a modern optimization lens
(Elsevier BV, 2019-07)We consider the well-known K-server problem from the perspective of mixed integer, robust and adaptive optimization. We propose a new tractable mixed integer linear formulation of the K-server problem that incorporates ... -
k-server via multiscale entropic regularization
(Association for Computing Machinery (ACM), 2018-06)© 2018 Copyright held by the owner/author(s). We present an O((log k)2)-competitive randomized algorithm for the k-server problem on hierarchically separated trees (HSTs). This is the first o(k)-competitive randomized ... -
K-theory of endomorphisms via noncommutative motives
(American Mathematical Society (AMS), 2015-07)We extend the K-theory of endomorphisms functor from ordinary rings to (stable) ∞-categories. We show that KEnd(-) descends to the category of noncommutative motives, where it is corepresented by the noncommutative motive ... -
K/ pi Fluctuations at Relativistic Energies
(American Physical Society, 2009-08)We report K/π fluctuations from Au+Au collisions at √[s[subscript NN]]=19.6, 62.4, 130, and 200 GeV using the STAR detector at the Relativistic Heavy Ion Collider. K/π fluctuations in central collisions show little dependence ... -
K13-Mediated Reduced Susceptibility to Artemisinin in Plasmodium falciparum Is Overlaid on a Trait of Enhanced DNA Damage Repair
(Elsevier BV, 2020-08)Southeast Asia (SEA) has been the breeding ground for malaria drug resistance, including resistance to artemisinin, the first-line anti-malarial drug. In this study, Xiong et al. find a relationship between DNA damage ... -
