This paper addresses the problem of indoor tracking of tagged objects with Ultra High Frequency (UHF) Radio Frequency Identification (RFID) systems. A new and more realistic observation model of the system is proposed, where the probability of detecting a tag by a reader is described by a Beta distribution. We model the probability of detection as a(More)
Hepatocellular carcinoma (HCC) was among the most common solid tumors which rated third in cancer-related mortality worldwide. Hepatitis B viral (HBV) infection represents an important risk factor for HCC. Long non-coding RNAs (lncRNAs) were a class of newfound non-coding RNAs widely depicted in the genome currently. Nevertheless, the potential roles of(More)
We propose a method for accurate real time indoor tracking of tagged objects in Ultra High Frequency (UHF) Radio Frequency Identification (RFID) systems. The method is based on aggregated binary measurements and a model that captures the uncertainty in the number of times that a tag is read while it is in the reading range of an RFID reader. The(More)
Directional sensors detect targets within a range and a predefined direction. In this paper, we assume that directional sensors are deployed in a sensor field, where at each node there are four collocated directional sensors providing a coverage of 360°. We extend results of some of our previous work on this subject and study the effects of different(More)
MicroRNAs (miRNAs) are a class of small, noncoding RNAs that act as key regulators in various physiological and pathological processes. However, the regulatory mechanisms for miRNAs in colorectal cancer remain largely unknown. Here, we found that miR-103 is up-regulated in colorectal cancer and its overexpression is closely associated with tumor(More)
It is well known that B-1 B cells are the main cell type that is responsible for the production of natural immunoglobulin M (IgM) and can respond to infection by increasing IgM secretion. However, we unexpectedly found that some epithelial cells also can express rearranged IgM transcript that has natural IgM characteristics, such as germline-encoded and(More)
The mammalian target of rapamycin (mTOR) is dysregulated in diverse cancers and contributes to tumor progression and drug resistance. The first generation of mTOR inhibitors have failed to show clinical efficiency in treating pancreatic cancers due in part to the feedback relief of the insulin-like growth factor-1 receptor (IGF-1R)-AKT signaling pathway.(More)
Hepatocellular carcinoma (HCC) is the fifth most common cancer in the world with poor prognosis. Here, we investigated the role of microRNA 218 (miR-218) in regulating human HCC development. Quantitative PCR (qPCR) was used to compare the expression levels of miR-218 between eight HCC and a normal liver cell lines, as well as nine primary HCC tissues and(More)
