Emerging evidence suggests that gut microbiota contribute to the treatment of post-inflammatory irritable bowel syndrome (PI-IBS). Our previous studies have demonstrated that a Chinese formula, Wuji Wan, has the ability to mitigate abdominal pain and diarrhea in PI-IBS rats. However, little is known about the underlying mechanism and whether the gut microbiota mediate the effect of Wuji Wan on ...

A wide area network (WAN) is a communications network utilizing devices such as telephone lines, satellite dishes, antennas, and microwaves to span a larger geographic area than can be covered by a local area network (LAN). Typically, a WAN consists of two or more LANs. A metropolitan area network, or MAN, is a term sometimes used to describe a system that falls somewhere between a WAN and LAN ...

We construct a three-country model to determine how the formation of free trade areas (FTAs) affects optimal tariffs and welfare. We find that, at constant rest of the world (ROW) tariffs, the adoption of internal free trade induces union members to reduce their external tariffs below the Kemp–Wan [J. Int. Econom. 6 (1976) 95–97] level, and causes ROW’s terms of trade to improve and its welfare...

WAN-in-Lab is a hardware testbed for the design, development, testing and evaluation of high speed network protocols. It uses real carrier-class networking hardware to avoid the artifacts introduced by network simulation and emulation, while being localized to allow detailed measurement of network performance. WAN-in-Lab is an open resource, available for use by the networking community. This p...

In this research, we propose an architectural solution to integrate the video voice over IP services in campus environment network and tested over LAN and WAN. Voice over IP technology has become a discussion issue for this time being. Today, the deployment of this technology on an organization truly can give a great financial benefit over traditional telephony. Therefore, this study is to anal...
