Ternary particle emission in spontaneous fission of 250Cf and 252Cf and in neutron induced fission of 249Cf and 251Cf [PDF]

, 2010
The emission probabilities and the energy distributions of tritons, α and 6He particles emitted in the spontaneous ternary fission (zero excitation energy) of 250Cf and 252Cf and in the cold neutron induced fission (excitation energy ≈ 6.5 MeV) of 249Cf ...

Stability and synthesis of superheavy elements: Fighting the battle against fission – example of 254No

EPJ Web of Conferences, 2016
Superheavy nuclei exist solely due to quantum shell effects, which create a pocket in the potential-energy surface of the nucleus, thus providing a barrier against spontaneous fission.

Small‐Scale Magnetic Soft Robots for Medical Applications: From Laboratory to Clinical Use

SmartBot, EarlyView.
Small‐scale magnetic soft robots are emerging as promising platforms for minimally invasive diagnosis and therapy in complex in vivo environments. This review compares untethered and tethered medical magnetic robots in parallel across five translational stages, from basic performance testing to clinical evaluation.

Spontaneous fission isomerism in uranium isotopes [PDF]

, 1970
A search for spontaneous fission isomerism in uranium and neptunium isotopes has resulted in the identification of a new isomer in 238U with a half-life of 195 ± 30 nsec.

Compartmentalisation in cAMP signalling: A phase separation perspective

British Journal of Pharmacology, EarlyView.
Cells rely on precise spatiotemporal control of signalling pathways to ensure functional specificity. The compartmentalisation of cyclic AMP (cAMP) and protein kinase A (PKA) signalling enables distinct cellular responses within a crowded cytoplasmic space.

Spontaneous fission [PDF]

, 1993
The spontaneous fission (SF) of the heaviest actinides and the transactinides is of particular interest because of the dramatic changes in properties observed in the region of the heavy fermion isotopes and for still heavier elements.

Neutron-induced fission: properties of prompt neutron and γ rays as a function of incident energy

EPJ Web of Conferences, 2016
We have applied the Hauser-Feshbach statistical theory, in a Monte-Carlo implementation, to the de-excitation of fission fragments, obtaining a reasonable description of the characteristics of neutrons and gamma rays emitted before beta decays toward ...

Spontaneous Fission Half-lives [PDF]

Progress of Theoretical Physics, 1958
A dynamical theory of nuclear distortion leading fission, is presented. This theory is based on_ the unified model (the collective model). But, since the spontaneous fission is, so to speak, an irreversible process, the present theory is treated reflecting this speciality.

Dissection of Mitochondrial Function via Chemical Perturbation and Single‐Cell Profiling

Cell Proliferation, EarlyView.
We establish a systematic framework to dissect mitochondrial function at the module level by combining targeted chemical perturbations with scRNA‐seq. This approach reveals shared and module‐specific programs linking mitochondrial activity to mito‐nuclear communication, stress response, and cell cycle, highlighting the tight coupling between ...

FISSION-TRACK DATING OF A TEPHRA LAYER IN THE ALAT FORMATION OF THE DANDIERO GROUP (DANAKIL DEPRESSION, ERITREA)

Rivista Italiana di Paleontologia e Stratigrafia, 2004
Attempts to date a biotite separate from a tephra layer recognized near Buia (Danakil Depression, Eritrea) in the liwer part of the Homo remains – bearing Dandiero group (formerly attributed to the Danakil Formation) using the 39Ar/40Ar method failed ...
