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, ...

Most of the genetic divergence that currently separates populations of Homo sapiens must have arisen during that long period when the local village (or band) was the basic unit of biological evolution. Studies of tribally intact Amerindian groups exhibiting such small-group organization have demonstrated marked genetic divergence between nearby villages. Some of this genetic radiation can be at...

In reactor calculations, a detailed 3-D power density distribution is required for core optimization studies and safety analyses. The general Monte Carlo based neutral particle transport tool, MCNP [1], has the capability to obtain detailed power density distribution in a reactor through its criticality calculation mode (KCODE mode). However, there is no standard tally type in MCNP that is able...

Measurements of mass and angular distributions have been made for fission-like outcomes in reactions forming isotopes flerovium (Z=114), using 48Ca, 50Ti, 54Cr projectiles. The dominant fast quasifission process, which masks the presence fusion-fission, has minimum yield at most backward angles, where sensitivity to fusion-fission is thus highest. In fitting angle spectra, only weak evidence a ...

Fission can have an important influence on the termination of the r process and on the abundances of long-lived actinides, which are relevant for the determination of the age of the Universe. Fission could also influence the abundances of nuclei in the region A~90 and 130 due to fission cycling. In order to quantitatively understand the fission role in the r process, two important pieces of inf...

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 est...
