Aiming at the positioning problem of wireless sensor network node location, an improved DV-hop positioning algorithm is proposed in this paper, together with its basic principle and realization issues. The proposed method can improve location accuracy without increasing hardware cost for sensor node. Simulation results show that it has good positioning(More)
This paper targets the identification of outlying sensors (that is, outlying reading sensors) and the detection of the reach of events in sensor networks. Typical applications include the detection of the transportation front line of some vegetation or animalcule's growth over a certain geographical region. We propose and analyze two novel algorithms for(More)
High-throughput DNA sequencing techniques allow for the identification and characterisation of microbes and their genes (microbiome). Using these new techniques, microbial populations in several niches of the human body, including the oral and nasal cavities, skin, urogenital tract and gastrointestinal tract, have been described recently. Very little data(More)
In this paper, we propose a new localization algorithm and improve the DV-Hop algorithm by using a differential error correction scheme that is designed to reduce the location error accumulated over multiple hops. This scheme needs no additional hardware support and can be implemented in a distributed way. The proposed method can improve location accuracy(More)
This paper applies and extends resource dependence theory (RDT) to comparatively investigate major factors that determine the level of cross-border mergers and acquisitions (M&As) by emerging market firms (EMFs) in developed and developing markets. We argue that the resource dependence logic of M&As (or simply the M&A logic) provides a unique perspective in(More)
Temperature and salt concentration are very helpful experimental conditions for a probe to hybridize uniquely to its intended target. In large families of closely related target sequences, the high degree of similarity makes it impossible to find a unique probe for every target. We studied how to select a minimum set of non-unique probes to identify the(More)
As a patient and recipient of a blood transfusion, it is important for him or her to receive the safest blood possible. Information about the donated blood should be under the track to guarantee the quality of the blood source. In this paper, we present a RFID-based blood information management system that aims at ensuring the quality of the blood and(More)
BACKGROUND Transfusion of RBC concentrates may cause adverse effects in the recipient, particularly when stored > 2 weeks. Prestorage removal of WBCs and platelets (leukoreduction, LR) improves clinical outcome in the human recipient. As blood ages during storage, progressive alterations in the structure and function of the cells occur. Changes in cell(More)
Metabolomics assays have recently been used in humans for the identification of biomarkers for dietary assessment and diseases. The application of metabolomics to feline nutrition, however, has been very limited. The objective of this study was to identify how the feline blood metabolome changed in response to dietary macronutrient composition. Twelve adult(More)
The objective was to evaluate the effects of dietary macronutrients and feeding frequency on blood glucose, insulin, total ghrelin and leptin. A total of twelve adult lean neutered male cats were used in three tests, all cross-over studies composed of a 15 d adaptation and blood sampling on day 16. In trial 1, differences between two- and four-meal feeding(More)
