The current Internet is being constructed from various kinds of wired and wireless access networks, and mobile hosts can connect to the Internet at any time and anywhere. In such an environment, mobile hosts need new technologies without closing connection or degrading the goodput during roaming these different networks. To overcome this, we propose an end-to-end seamless handover mechanism. In...

ID: 8181 Title: An algorithm to incorporate leaf transmission and head scatter corrections into step-and-shoot leaf sequences for IMRT Leaf transmission and head scatter are two most important factors that influence IMRT delivery and should be fully taken into account when generating MLC leaf sequences. Significant discrepancies between the desired and delivered intensity profiles could otherwi...

Following exposure of portions of mature maize (Zea mays L.) leaf strips to (14)CO(2), xylem exudate from the leaf strips contained [(14)C]sucrose. Sucrose was the only sugar in the xylem exudate which was obtained from the cut surface of the leaf strips by reducing the external pressure. The sucrose found in the xylem exudate apparently was obtained from the free space of the vascular bundles,...

The nomenclature of papaya viruses has been a source of confusion, primarily because symptomatology has been used extensively for describing papaya viruses. Although the literature is confusing and causal viruses for each of the diseases are not well identified, it appears that papaya viral diseases can generally be grouped as ring spot, mosaic and leaf curl, associated with poty, potex and gem...

Wireless Sensor Networks (WSNs) are used in a variety of applications today and will be used in even more applications in the future. However, WSNs tend to be less reliable than the wired networks we commonly work with mainly due to cheap hardware, low-power radios (with limited range) and limited energy supplies. An increasing number of applications especially in the context of industrial scen...

Quinoa is a promissory crop in the Andean region, on average, grain yield was 1.62 t ha-1 with nearly 2,000 year 2017. This study examined response of quinoa to radiation transmission, growth, and development different stages, under three planting densities order todetermine differential responses identify which aspects are determinants process yield. For present experiment, sowed differentdens...

Tomato spotted wilt virus (TSWV) is transmitted in a persistent propagative manner by Frankliniella occidentalis, the western flower thrips. While it is well established that vector competence depends on TSWV acquisition by young larvae and virus replication within the insect, the biological factors associated with frequency of transmission have not been well characterized. We hypothesized that...

Banded iron formations (BIF) have a particular vegetation type and provide a good model system for testing theories related to leaf phenology, due to unique stressful environmental conditions. As a consequence of the stressful conditions of BIF environment, we hypothesize that most species would retain at least some significant canopy cover, even at the end of the dry season, independently of g...

This study evaluated the basic dosimetric characteristics of a Dynamic Multi Leaf Collimator (DMLC) using a diode detector and film measurements for Intensity Modulated Radiation Therapy Quality Assurance (IMRT QA). The EGSnrc Monte Carlo (MC) simulation system was used for the determination of MLC characteristics. Radiation transmission and abutting leaf leakage relevant to the LinaTech DMLC H...
