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, 201112)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
(197609)There are languages which can be recognized by a deterministic (k+1)headed oneway finite automaton but which cannot be recognized by a kheaded oneway (deterministic or nondeterministic) finite automaton. Furthermore, ... 
K, Na distribution and unit cell parameters of alkali feldspars.

kCut: A Simple ApproximatelyUniform Method for Sampling Ballots in Postelection Audits
(Springer International Publishing, 201811)© 2020, International Financial Cryptography Association. We present an approximate sampling framework and discuss how risklimiting audits can compensate for these approximations, while maintaining their “risklimiting” ...

Kdistribution 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 ... 
KLines: A Theory of Memory
(19790601)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? ... 
Kmedian clustering, modelbased compressive sensing, and sparse recovery for earth mover distance
(Association for Computing Machinery (ACM), 201106)We initiate the study of sparse recovery problems under the EarthMover Distance (EMD). Specifically, we design a distribution over m x n matrices A such that for any x, given Ax, we can recover a ksparse approximation ... 
Kras Mutation Targeted to Gastric Tissue Progenitor Cells Results in Chronic Inflammation, an Altered Microenvironment, and Progression to Intraepithelial
(American Association for Cancer Research, 201011)Chronic infectious diseases, such as Helicobacter pylori infection, can promote cancer in a large part through induction of chronic inflammation. Oncogenic Kras mutation in epithelial cells activates inflammatory pathways, ... 
Krobots clustering of moving sensors using coresets
(Institute of Electrical and Electronics Engineers (IEEE), 201305)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 adhoc networking applications where interagent distances need to be minimized, ... 
The Kserver problem via a modern optimization lens
(Elsevier BV, 201907)We consider the wellknown Kserver problem from the perspective of mixed integer, robust and adaptive optimization. We propose a new tractable mixed integer linear formulation of the Kserver problem that incorporates ... 
kserver via multiscale entropic regularization
(Association for Computing Machinery (ACM), 201806)© 2018 Copyright held by the owner/author(s). We present an O((log k)2)competitive randomized algorithm for the kserver problem on hierarchically separated trees (HSTs). This is the first o(k)competitive randomized ... 
A />/kspace integral equation for describing propagation through a strongly inhomogeneous plasma density profile
(MIT Plasma Science and Fusion Center, 20150219) 
Kstability of Log Fano Cone Singularities
(Massachusetts Institute of Technology, 202205)In this thesis, we define the 𝛿invariant for log Fano cone singularities, and show that the necessary and sufficient condition for Ksemistability is 𝛿 ≥ 1. This generalizes the result of C. Li and K. Fujita. We also ... 
KStar rapid rotators and the detection of relatively young multiple KStar systems
(Massachusetts Institute of Technology, 2014)In this thesis, I searched through the Kepler light curves of 14,440 Kstar targets for evidence of periodicities that indicate rapid stellar rotation. Many Kepler M, K, and G stars show modulations in flux due to rotating ... 
Ktheoretic Hall algebras for quivers with potential
(Massachusetts Institute of Technology, 2020)Given a quiver with potential (Q, W), KontsevichSoibelman constructed a Hall algebra on the cohomology of the stack of representations of (Q, W). As shown by DavisonMeinhardt, this algebra comes with a filtration whose ... 
Ktheory and index theory on manifolds with boundary
(Massachusetts Institute of Technology, 1991) 
Ktheory of endomorphisms via noncommutative motives
(American Mathematical Society (AMS), 201507)We extend the Ktheory 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, 200908)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 ...
