In this paper, we simulate numerically the catastrophic disruption of a large asteroid as a result of a collision with a smaller projectile and the subsequent reaccumulation of fragments as a result o...
We investigate the morphology of size–frequency distributions (SFDs) resulting from impacts into 100-km-diameter parent asteroids, represented by a suite of 161 SPH/N-body simulations conducted to stu...
Allochthonous accreted terranes are exotic geologic units that originated from anomalous crustal regions on a subducting oceanic plate and were transferred to the overriding plate by accretionary proc...
Sugar beet is one of the most important industrial crops in Iran. For the last two decades it has been mainly affected by a destructive virus, beet necrotic yellow vein virus (BNYVV). The Polymyxa b...
We simulate the central reactions of $^{20}$Ne+$^{20}$Ne, $^{40}$Ar+$^{45}$Sc, $^{58}$Ni+$^{58}$Ni, $^{86}$Kr+$^{93}$Nb, $^{129}$Xe+$^{118}$Sn, $^{86}$Kr+$^{197}$Au and $^{197}$Au+$^{197}$Au at differ...
We simulate the central reactions of nearly symmetric, and asymmetric systems, for the energies at which the maximum production of IMFs occurs (E$_{c.m.}^{peak}$).This study is carried out by using ha...
Abstract: Approximate probabilities of formation of various atoms and ions in different bound states are determined for the exothermic nuclear $(n,{}^{6}$Li$;t,{}^{4}$He)-reaction of atomic lithium-6 ...
A mesoscopic model for heterogeneous DNA denaturation is developed in the framework of the path integral formalism. The base pair stretchings are treated as one-dimensional, time dependent paths contr...
The Western Cordillera of Ecuador consists of Cretaceous crustal fragments of oceanic plateaux and superimposed insular arcs, which were accreted to the northwestern South American margin during the ...
We present a method for the calculation of electronic structure of systems that contain tens of thousands of atoms. The method is based on the division of the system into mutually overlapping fragme...
We use SPH simulations to investigate the gravitational fragmentation of expanding shells through the linear and non--linear regimes.
This study examined the potential utility of DNA sequence analysis to discriminate and identify plant material in forensic investigations. DNA was extracted from plant leaf fragments of 11 species sto...
Efficient detection of spectator fragments is key to the main topics at an electron-ion collider (eIC). Any process which leads to emission of fragments or $\gamma$'s breaks coherence in diffractive p...
Using a multisource ideal gas (MSIG) model, we reconstruct the transverse emission source in the momentum space for light fragments produced in reactions 86Kr-124Sn at 25 MeV/nucleon and b=7—10 fm bas...
摘要随机扩增多态DNA(randomly amplified polymorphic DNA,RAPD)标记可快速提供连锁信息,特别是在针叶树单倍体的大配子体中RAPD基因型也能得以确定[3]。在对多态性的RAPD片段进行分析时,传统的平板凝胶电泳分析法因人工操作,其有效的鉴别受到一定程度的限制,只能得到一些有关RAPD片段半定量信息。我们将整合微流控芯片系统作为一种新的工具运用于黄山松的多态性R...
