K E E P E R : online conversation support scaffolding modeled after ancient and modern social technologies
(Massachusetts Institute of Technology, 2020)Emergence, when an entity is observed to have properties its parts do not have on their own, is an awe inducing phenomenon seen within nature, complex organization theory, physics, art, and philosophy. Humans can experience ... -
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+1 Heads are Better Than K
(1976-09)There are languages which can be recognized by a deterministic (k+1)-headed one-way finite automaton but which cannot be recognized by a k-headed one-way (deterministic or non-deterministic) finite automaton. Furthermore, ... -
K, Na distribution and unit cell parameters of alkali feldspars.

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-distribution fading models for Bayesian estimation of an underwater acoustic channel
(Massachusetts Institute of Technology, 2011)Current underwater acoustic channel estimation techniques generally apply linear MMSE estimation. This approach is optimal in a mean square error sense under the assumption that the impulse response fluctuations are well ... -
K-Lines: A Theory of Memory
(1979-06-01)Most theories of memory suggest that when we learn or memorize something, some "representation" of that something is constructed, stored and later retrieved. This raises questions like: How is information represented? ... -
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-shell ionization in collisions of heavy atoms.

A /->/k-space integral equation for describing propagation through a strongly inhomogeneous plasma density profile

K-stability of Log Fano Cone Singularities
(Massachusetts Institute of Technology, 2022-05)In this thesis, we define the 𝛿-invariant for log Fano cone singularities, and show that the necessary and sufficient condition for K-semistability is 𝛿 ≥ 1. This generalizes the result of C. Li and K. Fujita. We also ... -
K-Star rapid rotators and the detection of relatively young multiple K-Star systems
(Massachusetts Institute of Technology, 2014)In this thesis, I searched through the Kepler light curves of 14,440 K-star targets for evidence of periodicities that indicate rapid stellar rotation. Many Kepler M, K, and G stars show modulations in flux due to rotating ... -
K-theoretic Hall algebras for quivers with potential
(Massachusetts Institute of Technology, 2020)Given a quiver with potential (Q, W), Kontsevich-Soibelman constructed a Hall algebra on the cohomology of the stack of representations of (Q, W). As shown by Davison-Meinhardt, this algebra comes with a filtration whose ... -
K-theory and index theory on manifolds with boundary

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 ...
