User generated online reviews on products or services are valuable to other users to make informed decisions. Thus, identifying experts in reviewers becomes important. We tackle the problem of reviewer expertise ranking in online review datasets by analyzing the bipartite graphs of reviewers and reviewed items, an approach that has not been considered in previous studies of the problem. We use ...

From an evolutionary perspective, the Dictyostelium centrosome is an intriguing organelle. Like its counterpart in yeast, the spindle pole body, it exhibits a compact, layered structure that lacks the centrioles typical of metazoan cells, but as in the latter, the core is surrounded by an electron-dense, amorphous matrix. With vertebrate centrosomes it shares a cytoplasmic localization in inter...

Optical landmark navigation using craters on the surface of a central body was first used operationally by the Near Earth Asteroid Rendezvous (NEAR) mission. It has proven to be a powerful data type for determining spacecraft orbits above the target for close flybys and low altitude orbiting. Tracking individual landmarks, which are small craters, enables orbit determination accuracies on the o...

BACKGROUND Hypertriglyceridemia (HTG) is the most common etiology of acute pancreatitis (AP) after alcohol and gallstone-induced disease. Elevation of serum triglyceride (TG) levels to ≥ 1000 mg/dl in a patient with AP strongly indicates HTG as the cause. The absolute risk of pancreatitis based on serum TG ≤ 1000 mg/dl has not been clearly defined. The aims of this study were to address the rol...

Olfactory system neural oscillations as seen in the local field potential have been studied for many decades. Recent research has shown that there is a functional role for the most studied gamma oscillations (40–100 Hz in rats and mice, and 20 Hz in insects), without which fine odor discrimination is poor. When these oscillations are increased artificially, fine discrimination is increased, and...

In this paper we analyse the security of the SHA-3 candidate ARIRANG. We show that bitwise complementation of whole registers turns out to be very useful for constructing high-probability differential characteristics in the function. We use this approach to find nearcollisions with Hamming weight 32 for the full compression function as well as collisions for the compression function of ARIRANG ...

A greatly simplified radioimmunoassay for bradykinin in human plasma is described. Current techniques require multiple chromatographic steps or extraction procedures with analytical recoveries of bradykinin of often less than 60%. We present a method in which bradykinin is separated from components of higher relative molecular mass (including kininogens) in a single step, by use of a column of ...

Triadin 1 (TRD) is an integral membrane protein that associates with the ryanodine receptor (RyR2), calsequestrin (CASQ2) and junctin to form a macromolecular Ca signaling complex in the cardiac junctional sarcoplasmic reticulum (SR). To define the functional role of TRD, we examined the effects of adenoviral-mediated overexpression of the wild-type protein (TRD(WT)) or a TRD mutant lacking the...

Adipocyte differentiation is probably controlled by transcriptional and post-transcriptional regulation. Longissimus lumborum from Angus steers (aged 155 d; seven animals per diet) fed high-starch or low-starch diets for 112 d (growing phase) followed by a common high-starch diet for an additional 112 d (finishing phase) was biopsied at 0, 56, 112 and 224 d for transcript profiling via quantita...
