(ACM|CHI Conference on Human Factors in Computing Systems, 2022-04-29) -
¹⁷O MAS NMR Correlation Spectroscopy at High Magnetic Fields
(American Chemical Society (ACS), 2017-11)The structure of two protected amino acids, FMOC-l-leucine and FMOC-l-valine, and a dipeptide, N-acetyl-l-valyl-l-leucine (N-Ac-VL), were studied via one- and two-dimensional solid-state nuclear magnetic resonance (NMR) ... -
¹⁷O NMR Investigation of Water Structure and Dynamics
(American Chemical Society (ACS), 2016-08)The structure and dynamics of the bound water in barium chlorate monohydrate were studied with ¹⁷O nuclear magnetic resonance (NMR) spectroscopy in samples that are stationary and spinning at the magic-angle in magnetic ... -
O(1)-approximations for maximum movement problems
(Springer Berlin / Heidelberg, 2011-08)We develop constant-factor approximation algorithms for minimizing the maximum movement made by pebbles on a graph to reach a configuration in which the pebbles form a connected subgraph (connectivity), or interconnect a ... -
An O(log n/log log n)-approximation algorithm for the asymmetric traveling salesman problem
(Society for Industrial and Applied Mathematics, 2010-01)We consider the Asymmetric Traveling Salesman problem for costs satisfying the triangle inequality. We derive a randomized algorithm which delivers a solution within a factor O(log n/ log log n) of the optimum with high ... -
An O(Nm) Time Algorithm for Finding the Min Length Directed Cycle in a Graph
(Society for Industrial and Applied Mathematics, 2016-10)In this paper, we introduce an O(nm) time algorithm to determine the minimum length directed cycle (also called the "minimum weight directed cycle") in a directed network with n nodes and m arcs and with no negative length ... -
O-antigen diversity and lateral transfer of the wbe region among Vibrio splendidus isolates
(Blackwell Publishing, 2010-11)The O-antigen is a highly diverse structure expressed on the outer surface of Gram-negative bacteria. The products responsible for O-antigen synthesis are encoded in the wbe region, which exhibits extensive genetic diversity. ... -
O-site and T-site Occupation of α-phase PdH[subscript x] and PdD[subscript x]
(International Society of Condensed Matter Nuclear Scientists (ISCMNS), 2015)An important study of the solubility of hydrogen in α-phase PdH[subscript x] and deuterium in α-phase PdH[subscript x] over a wide temperature range was published by Clewley et al. (J. Chem. Soc., Faraday Trans. 1: Phy. ... -
O3-type Na(Mn[subscript 0.25]Fe[subscript 0.25]Co[subscript 0.25]Ni[subscript 0.25])O[subscript 2]: A quaternary layered cathode compound for rechargeable Na ion batteries
(Elsevier, 2014-10)We report a new layered Na(Mn[subscript 0.25]Fe[subscript 0.25]Co[subscript 0.25]Ni[subscript 0.25])O[subscript 2] compound with O3 oxygen stacking. It delivers 180 mAh/g initial discharge capacity and 578 Wh/kg specific ... -
O[superscript 6]-Methylguanine DNA lesions induce an intra-S-phase arrest from which cells exit into apoptosis governed by early and late multi-pathway signaling network activation
(Royal Society of Chemistry, The, 2012-08)The O[superscript 6]-methylguanine (O[superscript 6]MeG) DNA lesion is well known for its mutagenic, carcinogenic, and cytotoxic properties, and understanding how a cell processes such damage is of critical importance for ... -
Oasis: procedurally generated social virtual spaces from 3D scanned real spaces
(Institute of Electrical and Electronics Engineers (IEEE), 2018-12)We present Oasis, a novel system for automatically generating immersive and interactive virtual reality environments for single and multiuser experiences. Oasis enables real-walking in the generated virtual environment by ... -
Obesity accelerates Helicobacter felis-induced gastric carcinogenesis by enhancing immature myeloid cell trafficking and TH17 response
(BMJ Publishing Group, 2013-05)Objective: To investigate the role of obesity-associated inflammation and immune modulation in gastric carcinogenesis during Helicobacter-induced chronic gastric inflammation. Design: C57BL/6 male mice were infected ... -
Obesity, Acute Kidney Injury, and Mortality in Critical Illness
(Wolters Kluwer - Lippincott Williams & Wilkins, 2016-02)Objectives: Although obesity is associated with risk for chronic kidney disease and improved survival, less is known about the associations of obesity with risk of acute kidney injury and post acute kidney injury mortality. ... -
Obfuscating Conjunctions under Entropic Ring LWE
(Association for Computing Machinery, 2016-01)We show how to securely obfuscate conjunctions, which are functions f(x[subscript 1], . . . , x[subscript n]) = ∧[subscript i∈I] y[superscript i] where I ⊆ [n] and each literal y[subscript i] is either just x[subscript ... -
Obfuscation in mutual funds

Obfuscation of Probabilistic Circuits and Applications
(Springer Nature America, Inc, 2015)© International Association for Cryptologic Research 2015. This paper studies the question of how to define, construct, and use obfuscators for probabilistic programs. Such obfuscators compil a possibly randomized program ... -
Obfuscation, Learning, and the Evolution of Investor Sophistication
(Oxford University Press for the Society for Financial Studies, 2010-09)Investor sophistication has lagged behind the growing complexity of retail financial markets. To explore this, we develop a dynamic model to study the interaction between obfuscation and investor sophistica- tion in ... -
