¹⁷O MAS NMR Correlation Spectroscopy at High Magnetic Fields
(American Chemical Society (ACS), 201711)The structure of two protected amino acids, FMOClleucine and FMOClvaline, and a dipeptide, Nacetyllvalyllleucine (NAcVL), were studied via one and twodimensional solidstate nuclear magnetic resonance (NMR) ... 
¹⁷O NMR Investigation of Water Structure and Dynamics
(American Chemical Society (ACS), 201608)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 magicangle in magnetic ... 
O(1)approximations for maximum movement problems
(Springer Berlin / Heidelberg, 201108)We develop constantfactor 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, 201001)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, 201610)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 ... 
Oantigen diversity and lateral transfer of the wbe region among Vibrio splendidus isolates
(Blackwell Publishing, 201011)The Oantigen is a highly diverse structure expressed on the outer surface of Gramnegative bacteria. The products responsible for Oantigen synthesis are encoded in the wbe region, which exhibits extensive genetic diversity. ... 
Osite and Tsite Occupation of αphase 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 αphase PdH[subscript x] and deuterium in αphase PdH[subscript x] over a wide temperature range was published by Clewley et al. (J. Chem. Soc., Faraday Trans. 1: Phy. ... 
O3type 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, 201410)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 intraSphase arrest from which cells exit into apoptosis governed by early and late multipathway signaling network activation
(Royal Society of Chemistry, The, 201208)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), 201812)We present Oasis, a novel system for automatically generating immersive and interactive virtual reality environments for single and multiuser experiences. Oasis enables realwalking in the generated virtual environment by ... 
Obesity accelerates Helicobacter felisinduced gastric carcinogenesis by enhancing immature myeloid cell trafficking and TH17 response
(BMJ Publishing Group, 201305)Objective: To investigate the role of obesityassociated inflammation and immune modulation in gastric carcinogenesis during Helicobacterinduced chronic gastric inflammation. Design: C57BL/6 male mice were infected ... 
Obesity, Acute Kidney Injury, and Mortality in Critical Illness
(Wolters Kluwer  Lippincott Williams & Wilkins, 201602)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, 201601)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 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, 201009)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 ...

Object classification through scattering media with deep learning on time resolved measurement
(The Optical Society, 2017)© 2017 Optical Society of America. We demonstrate an imaging technique that allows identification and classification of objects hidden behind scattering media and is invariant to changes in calibration parameters within a ... 
Object decoding with attention in inferior temporal cortex
(National Academy of Sciences (U.S.), 201105)Recognizing objects in cluttered scenes requires attentional mechanisms to filter out distracting information. Previous studies have found several physiological correlates of attention in visual cortex, including larger ...
