in this study, a general theoretical model to foresee and calculate the current-voltagecharacteristics in a plateau zone and the associated efficiency of the neutron detector (sensitivity) is presented. this study is to complete the previous studies in this field. the model also considers electric field distortion resulting from the charge collection effect. the characteristics curve is obtaine...

A charged system search algorithm (CSS) is applied to the optimal cost design of water distribution networks. This algorithm is inspired by the Coulomb and Gauss’s laws of electrostatics in physics. The CSS utilizes a number of charged particles which influence each other based on their fitness values and their separation distances considering the governing law of Coulomb. The well-known benchm...

The results of model calculations on nuclide yields produced by firstchance fission of excited U nuclei are presented. The calculations show the washing out of structural effects (even-odd structure and fission channels), the broadening of the mass distribution and the reduction of the neutron excess with increasing excitation energy. The calculations are relevant for the design of future secon...

The GTPase dynamin polymerizes into a helical coat that constricts membrane necks of endocytic pits to promote their fission. However, the dynamin mechanism is still debated because constriction is necessary but not sufficient for fission. Here, we show that fission occurs at the interface between the dynamin coat and the uncoated membrane. At this location, the considerable change in membrane ...

an analysis of selected fission fragment angular distributions from helium-ion induced fission is made using an exact theoretical expression. theoretical anisotropies obtained with the transition state model are compared with their corresponding values deduced from the statistical scission model. the nuclear moment of inertia extracted from the model calculations are compared with their estimat...

in this work, we had examined 7 different types of neutron sources -an isotropic point source, sending 14.1(mev) monoenergetic neutrons ,an spherical source with 30 micron radius sending 14.1 (mev) monoenergetic neutrons, and a 30 micron radius spherical source having gaussian fusion energy spectrum from a d-t fusion, with different bandwidths -1,10,50,100 and 1000 kev and investigated 5 differ...

Mitochondria are dynamic organelles and continuously undergo fission and fusion processes. Mitochondrial fission is involved in multiple physiological or pathological processes, but the role of mitochondrial fission of smooth muscle cells in artery constriction is unknown. The role of mitochondrial fission of smooth muscle cells in arterial function was investigated by measuring the tension of ...

Opposing fission and fusion events maintain the yeast mitochondrial network. Six proteins regulate these membrane dynamics during mitotic growth-Dnm1p, Mdv1p, and Fis1p mediate fission; Fzo1p, Mgm1p, and Ugo1p mediate fusion. Previous studies established that mitochondria fragment and rejoin at distinct stages during meiosis and sporulation, suggesting that mitochondrial fission and fusion are ...

Spontaneous-fission properties of 256 Fm, 258 Fm, and 260 Fm isotopes are studied within the Skyrme-Hartree-Fock+BCS framework. In the particle-hole channel we take the Skyrme SkM * effective force, while in the particle-particle channel we employ the seniority pairing interaction. Three static fission paths for all investigated heavy fermium isotopes are found. The analysis of these fission mo...

Prompt and $\beta$-delayed fission observables, such as the average number of prompt delayed neutrons, independent cumulative product yields, $\gamma$-ray energy spectra for photonuclear reactions on $^{235,238}$U $^{239}$Pu are calculated with Hauser-Feshbach Fission Fragment Decay (HF$^3$D) model compared available experimental data. In analysis neutron-induced to case photo-induced fission, ...
