The concept of source and sink strength is presently well-recognized and accepted by the scientific community as a pertinent approach describing the mechanisms of carbohydrate partitioning into the different and competing organs at a whole plant or canopy scales. Sink–source relationships have a clear role in the size of sink organs. Besides the effect on organ size, sink/source ratio might also...

Design: 15 large hyperplastic polyps (>1 cm), including 4 with dysplastic foci, 10 small hyperplastic polyps (≤1 cm), and 9 gastric adenomas were evaluated for immunohistochemical expression of MGMT, MLH-1, β-catenin, p27, p16, and p53. Polyps with dysplasia or abnormal β-catenin expression were assessed for APC and β-catenin (CTNNB1) mutations. Large hyperplastic polyps and adenomas were analy...

Restaurant inspection reports are an important source of information for the public to evaluate food safety practices at restaurants. This study examined the effect of information source and message style on consumer responses to restaurant inspection reports. The study employed a three (Information source: local health department, newspaper or consumer blog) x three (Message style: numeric, le...

In this chapter, we introduce a generic Internet trading framework for online auctions. We present the requirements and service of the framework. A generic OR/XOR bidding language that can express different OR/XOR combinations is adopted for Web interfaces. The framework is implemented with free open-source technologies already successfully tested in industries. Researchers can use the platform...

This paper applies Shannon theory, which was established to describe a discrete general communications system, to a general identification system that is affected by noise (and jamming), the probability of a discrete event occurring (such as an object in a certain region of space), and most importantly, the entropy and dissonance of the information source. This paper analyzes the cause of the m...

We study the equilibrium structure of large but finite aggregates of magnetic dipoles, representing a colloidal suspension of magnetite particles in a ferrofluid. With increasing system size, the structural motif evolves from chains and rings to multi-chain and multi-ring assemblies. Very large systems form single- and multi-wall coils, tubes and scrolls. These structural changes result from a ...

It has been recently discovered that the synthesis of Al-Ge imogolite-like nanotubes is possible at high concentration. Despite this initial success, the structure of these Al-Ge imogolite-like nanotubes remains not completely understood. Using high resolution cryo-TEM and Small Angle X-ray Scattering, we unravel their mesoscale structure in two contrasted situations. On the one hand, Al-Ge imo...

Obsidian artifacts recently have been recovered from 18 archaeological sites on eight islands across the Kuril Island archipelago in the North Pacific Ocean, suggesting a wide-ranging distribution of obsidian throughout the island chain over the last 2,500 years. Although there are no geologic sources of obsidian in the Kurils that are known to have been used prehistorically, sources exist in H...
