— In intermittently connected sensor networks, wherein sensor nodes do not always have connected paths to the base station, preserving generated data inside the network is a new and challenging problem. We propose to preserve the data items by distributing them from storage-depleted data generating nodes to sensor nodes with available storage space and high(More)
Data generated in sensor networks may have different importance and priority. Different types of data contribute differently for scientists to analyze the physical environment. In a challenging environment, wherein sensor nodes do not always have connected paths to the base station, and not all the data can be preserved inside the network due to severe(More)
Mesenchymal stem cells (MSCs) have been accepted as a promising cell source in tissue repair and regeneration. However, the inability to enrich MSCs in target areas limits their wide application. As a result, it has been a major goal to induce MSCs to be abundantly and specifically recruited to the injury site. In this study, a peptide with a specific(More)
The aim of this study was to investigate the antioxidant potential of ampelopsin (APS) by using various methods in vitro, as well as to determine effects of APS on LPS-induced oxidative stress in piglets. The results showed that APS exhibited excellent free radical scavenging by DPPH, ABTS, O2•-, H2O2 and ferric reducing antioxidant power. Ampelopsin also(More)
In order to investigate the mechanism of apoptosis in rat intestinal epithelial cells (IEC-6) induced by hydrogen peroxide (H2O2), IEC-6 cells were subjected to 20 μmol/L H2O2 and cell proliferation activity was determined using 3-(4,5-dimethyl-2-yl)-2,5-diphenyltetrazolium bromide. Cell morphology was observed by microscopy and cell apoptosis was detected(More)
Detecting the person's unwonted behavior state timely and correctly in home environment for the service robot is a fundamental problem. This paper proposes an approach to this problem using the position and pose information as the features and the computing result of the CRF model as the judging gist. Firstly, a pose template based on position label is(More)
