Maximum likelihood estimation in many classical statistical problems is beset by multimodality. This article explores several variations of deterministic annealing that tend to avoid inferior modesExpand
Sinomenine ameliorates arthritis via MMPs, TIMPs, and cytokines in rats.
Rheumatoid arthritis (RA) is a chronic, inflammatory autoimmune disease that results in progressive joint destruction and substantial morbidity. The stem of the Chinese medicinal plant, SinomeniumExpand
Regression Models for Multivariate Count Data
ABSTRACT Data with multivariate count responses frequently occur in modern applications. The commonly used multinomial-logit model is limiting due to its restrictive mean-variance structure. ForExpand
Provable Convex Co-clustering of Tensors
We bridge the gap between statistical guarantees and computational efficiency for existing tensor clustering solutions due to the nature of their non-convex formulations of tensor co-clustering. Expand
Ginseng protects rodent hearts from acute myocardial ischemia-reperfusion injury through GR/ER-activated RISK pathway in an endothelial NOS-dependent mechanism.
ETHNOPHARMACOLOGICAL RELEVANCE Ginseng (Panax ginseng C.A. Meyer) is widely used in Asian communities for treating cardiovascular diseases. However, the mechanism by which it protects the myocardiumExpand
Directional Fluid Transport in Thin Porous Materials and its Functional Applications.
Directional fluid motion driven by the surface property of solid substrate is highly desirable for manipulating microfluidic liquid and collecting water from humid air. Studies on such liquid motionExpand
Chemical and DNA authentication of taste variants of Gynostemma pentaphyllum herbal tea.
Gynostemma pentaphyllum Makino (Gp) was once used as a sweetener in Japan and is now widely consumed as an herbal tea worldwide for lowering cholesterol levels. Two taste variants, bitter and sweet,Expand
A new approach for authentication of four ginseng herbs and their related products based on the simultaneous quantification of 19 ginseng saponins by UHPLC-TOF/MS coupled with OPLS-DA
White ginseng, red ginseng, notoginseng and American ginseng are commonly called ginseng herbs and are frequently used as traditional Chinese medicine (TCM) and dietary supplements in China. AlthoughExpand
A feasible image-based colorimetric assay using a smartphone RGB camera for point-of-care monitoring of diabetes.
Urinary glucose determination using a glucose test strip is simple and convenient in daily self-monitoring of diabetes. However, diabetic patients exhibit acquired impaired color vision (ICV), whichExpand
