We demonstrate that, in the classical non-stochastic regret minimization problem with d decisions, gains and losses to be respectively maximized or minimized are fundamentally different. Indeed, by considering the additional sparsity assumption (at each stage, at most s decisions incur a nonzero outcome), we derive optimal regret bounds of different orders. Specifically, with gains, we obtain a...

Soda lakes are extreme habitats characterized by high pH, high salt content, and occasionally associated with elevated concentrations of trace elements from volcanic origins, including arsenic (As). We characterized the bacterial community associated with a soda lake in Khovsgol, Mongolia by using both cultivation-independent and -dependent methods. Geochemical analysis of the salt evaporites p...

In this paper, we propose a novel action recognition framework. The method uses pictorial structures and shrinkage optimized directed information assessment (SODA) coupled with Markov Random Fields called SODA+MRF to model the directional temporal dependency and bidirectional spatial dependency. As a variant of mutual information, directional information captures the directional information flo...

one of the solutions to increase the applications of lignin molecules is increasing reactive functional groups by chemical modification. adding reactive functional groups into the lignin structures is one the best proposed methods. the aim of this study was to investigate change in structure as well as glass transition temperature (tg) of soda and kraft lignins after hydroxymethylation them wit...

BACKGROUND & AIMS Non-alcoholic fatty liver disease affects ∼30% of US adults, yet the role of sugar-sweetened beverages and diet soda on these diseases remains unknown. We examined the cross-sectional association between intake of sugar-sweetened beverages or diet soda and fatty liver disease in participants of the Framingham Offspring and Third Generation cohorts. METHODS Fatty liver diseas...

OBJECTIVE In patients with type 2 diabetes, but not type 1 diabetes, abnormal secretion of incretins in response to oral nutrients has been described. In healthy youths, we recently reported accentuated glucagon-like peptide 1 (GLP-1) secretion in response to a diet soda sweetened with sucralose and acesulfame-K. In this study, we examined the effect of diet soda on gut hormones in youths with ...

The ferric uptake regulation (fur) gene product participates in regulating expression of the manganeseand iron-containing superoxide dismutase genes of Escherichia coli. Examination of ,-galactosidase activity coded from a chromosomal d(sodA'-'lacZ) fusion suggests that metallated Fur protein acts as a transcriptional repressor of sodA (manganese superoxide dismutase [MnSOD]). Gel retardation a...

OBJECTIVE We determined associations between diet soda consumption and risk of incident metabolic syndrome, its components, and type 2 diabetes in the Multi-Ethnic Study of Atherosclerosis. RESEARCH DESIGN AND METHODS Diet soda consumption was assessed by food frequency questionnaire at baseline (2000-2002). Incident type 2 diabetes was identified at three follow-up examinations (2002-2003, 2...

We present the Smart Object, Dumb Archive (SODA) model for digital libraries (DLs). The SODA model transfers functionality traditionally associated with archives to the archived objects themselves. We are exploiting this shift of responsibility to facilitate other DL goals, such as interoperability, object intelligence and mobility, and heterogeneity. Objects in a SODA DL negotiate presentation...
