This paper considers the problem of how to implement a file system on Storage Class Memory (SCM), that is directly connected to the memory bus, byte addressable and is also non-volatile. In this paper, we propose a new file system, called SCMFS, which is implemented on the virtual address space. In SCMFS, we utilize the existing memory management module in(More)
BACKGROUND Colorectal liver metastases (CLM) occur frequently and postoperative intestinal infection is a common complication. Our previous study showed that probiotics could decrease the rate of infectious complications after colectomy for colorectal cancer. To determine the effects of the perioperative administration of probiotics on serum zonulin levels(More)
Ileocolic anastomosis is an essential step in the treatment to restore continuity of the gastrointestinal tract following ileocolic resection in patients with Crohn’s disease (CD). However, the association between anastomotic type and surgical outcome is controversial. The aim of this meta-analysis is to compare surgical outcomes between stapled(More)
The effect of exogenous reduced glutathione (GSH) on alleviation of hexavalent chromium (Cr(6+)) toxicity to rice seedlings and its physiological mechanisms were comprehensively investigated in a series of experiments. Our results showed that growth and nutrient uptake of rice seedlings were dramatically reduced under 100 μM Cr(6+) stress, and the reduction(More)
Increasing evidence suggests that lineage specific subpopulations and stem-like cells exist in normal and malignant breast tissues. Epigenetic mechanisms maintaining this hierarchical homeostasis remain to be investigated. In this study, we found the level of microRNA221 (miR-221) was higher in stem-like and myoepithelial cells than in luminal cells(More)
This paper considers the problem of efficiently managing storage space in a hybrid storage system employing flash and disk drives. The flash and disk drives exhibit different performance characteristics of read and write behavior. We propose a technique for balancing the workload properties across flash and disk drives in such a hybrid storage system. The(More)
BACKGROUND AND AIMS Bone marrow-derived mesenchymal stem cell (MSC) is widely studied in inflammatory bowel disease (IBD) in basic and clinical research. However, patients with IBD have higher risk of developing colorectal cancer and MSC has dual effect on tumorigenesis. This study aims to evaluate the role of MSC on tumorigenesis of IBD. METHODS MSCs(More)
We develop a fast approximation algorithm called rounded dynamic programming (RDP) for stochastic network design problems on directed trees. The underlying model describes phenomena that spread away from the root of a tree, for example, the spread of influence in a hierarchical organization or fish in a river network. Actions can be taken to intervene in(More)
