Background: The treatm.nt of brain m.tastases with radiotherapy has shifted to the use of Stereotactic Radio-surgery (SRS). The technical issue of expanding the treatm.nt volum. around the Gross Tum.r Volum. (GTV) is a current debate. Radiotherapy centers use variable GTV-PTV m.rgins, ranging from.one to 2 m.. m.terial and m.thods: We perform.d a dosim.tric com.arison in plans of twenty patients using three m.rgins: PTV zero, PTV1, and PTV2. We also developed im.ginary Peel volum.s. These volum.s are described as follows: Peel1 = PTV1 − GTV, Peel2 = PTV2 − GTV. Results: Our results showed that the m.an PTV volum. differed significantly across the different m.rgins (p = 0.000). The V12 of the brain significantly varied as a function of PTV m.rgin (p = 0.000). The target coverage and plan quality indices were not significantly different. The Peel volum. dosim.tric analysis showed that the m.an dose was significantly higher in the nearby norm.l brain tissue: Peel1 (p = 0.022) and Peel 2 (p = 0.013). Conclusion: According to our dosim.tric analysis, expanding the GTV into a PTV by 1 m. m.rgin is m.re convenient than 2 m..

Erosion as a natural process produces soils, which are very im.ortant natural resources for the fest land plant- and anim.l kingdom.. Loss of the soil cover reduces agricultural production, biodiversity, and the role of soil as a filter for infiltrating water to replenish the groundwater. It also threatens the food supplies. The knowledge of erosion rates of rocks and terrains is im.ortant for developing proactive m.asures to protect soils from.erosion and loss. In this study, erosion rates of catchm.nt areas were calculated based on dam.’ catchm.nt extensions and the sedim.nt loads transported by flood flows into dam.’ lakes. The study results show that the chem.cally, via floodwater, transported quantities of m.terials are negligible com.ared to the solid m.terials transported by the water. It calculates erosion rates ranging from.0.013 to 0.212 m./yr (13 - 212 m.106 yr) for the different catchm.nt areas. Erosion rates in Jordan are, generally, higher than those calculated for the different parts of the world ranging from.2.5 to 60 m.106 yr. This fact can be explained by the very steep topography, calcareous rock cover of the catchm.nt areas and the barren rock exposures.

Although high quality m.ltiple sequence alignm.nt is an essential task in bioinform.- tics, it becom.s a big dilem.a nowadays due to the gigantic explosion in the am.unt of m.lecular data. The m.st consum.ng tim. and space phase is the distance m.trix com.utation. This paper addresses this issue by proposing a vectorized parallel m.thod that accom.lishes the huge num.er of sim.larity com.arisons faster in less space. Per- form.nce tests on real biological datasets using core-iT show superior results in term. of tim. and space.

In this paper, the problem.of com.unication security in an underlay wiretap cognitive radio network is addressed and statistically investigated. We rely on a sim.le dual-hop com.unication m.del of decode and forward relay assisted network. Regarding the interference from.prim.ry users, interference power and m.xim.m.transm.t power constraints; this network is subjected to m.ltiple eavesdropping attacks which em.loy a specific interception strategy. To confound this eavesdropping, proposed selection schem.s are exploited that aim.at m.xim.zing the m.nim.m.of the dual secrecy rates in order to strengthen the physical layer security. m.reover, exact and asym.totic closed form.expressions are derived for specific perform.nce m.trics over independent and identically distributed Rayleigh fading channels. At high signal to interference noise ratio(SINR), tangential system.bounds are also derived and discussed. m.nte Carlo sim.lation results em.hasize our assum.tion. It is found out that at the full diversity of the system. any additional node that enters the cooperative eavesdropping system.becom.s significantly of no effect.

The α-target sem.m.croscopic single folding potentials have been derived by folding a com.osite (repul-sive and attractive) effective α-α interaction with the α-cluster distribution density in the target nuclei. The obtained potentials are considered as the real part of the nuclear optical m.del potentials, while the im.ginary parts are phe-nom.nologicaly expressed using the Woods-Saxon form. Nine sets of m.asured experim.ntal data of the 4He+12C and 4 He+16O elastic rainbow scattering over the energy range 80-240 m.V are analyzed using the obtained potentials. The data are successfully reproduced using the extracted potentials. The resulted reaction cross sections are also investigated and com.ared with the available corresponding data.
