Abstract To reduce or completely remove the viewing angle dependence of liquid crystal (LC) displays and devices, we have recently introduced a new electrode structure for LC displays. This has openings (holes) in pixel (PixE) generating fringe electric field with azimuthal degenerated distribution lines around each hole, resembling fountain. Such is promoting azimuthally switching molecules th...

background: due to the lack of proper rail road and air transportation, most commutes in iran are carried out by buses. in most cases, the water in the busses is used for passengers for drinking usage. although this kind of water source has provided convince for the travelers, it could be a great risk in disease outbreak. the aim of this study is to determine the water quality in commuting buse...

Code dissemination in wireless ad hoc network is an important aspect of network deployment. Once deployed, the network nodes may still need software updates to keep up with the changing application demand, thus making wireless broadcast an important aspect of any wireless network deployment. We present FBcast, a new broadcast protocol based on the principles of modern erasure codes. FBcast prov...

background and purpose: school, as a reliable place in educating students, has an important role in training. the aim of this study was the assessment of environmental health of primary schools in norabad mamasani city of fars province. materials and methods: in this analytical-descriptive and cross-sectional study, all of 26 primary schools in norabad mamasani city were surveyed by using censu...

We introduce LT codes, the first rateless erasure codes that are very efficient as the data length grows.

The mechanisms controlling organismal aging have yet to be clearly defined. In our recent paper [1], we revealed thatTAp63, the p53 family member, is a critical gene in preventing organismal aging by controlling the maintenance of dermal and epidermal precursor and stem cells critical for wound healing and hair growth. In the absence of TAp63, dermal stem cells (skin-derived precursors or SKPs)...

When a positively buoyant vertical fluid jet directed downwards from its source impinges on a horizontal flat surface, the resulting flow is termed an “impinging fountain”. These flows arise in a number of practical situations, for example, in gas metal arc welding (GMAW). Developing a description of this flow presents the researcher with a number of challenges and forms the motivation for this...
