Multifaceted impact of shape coexistence in proton-rich nuclei within a beyond-mean-field model [PDF]

EPJ Web of Conferences
The proton-rich medium mass nuclei bring insights into fundamental symmetries and interactions. Exotic behavior manifested by the appearance of isomeric states, their feeding by the β decay of the neighboring nuclei as well as their complex decay are ...

Shape coexistence in 178Hg

Physical Review C, 2019
Lifetime measurements of excited states in 178 Hg have been performed using the 103 Rh ( 78 Kr , p 2 n ) reaction at a beam energy of 354 MeV. The recoil-decay tagging (RDT) technique was applied to select the 178 Hg nuclei and associate the prompt γ rays with the correlated characteristic ground-state α decay. Lifetimes of the four lowest yrast states

Shape Coexistence in Odd-Z Isotopes from Fluorine to Potassium

Particles
The shape of a nucleus is one of its fundamental properties. We conduct a systematic investigation of shape coexistence in odd-Z nuclei from fluorine to potassium using the deformed relativistic Hartree–Bogoliubov theory in continuum. First, we present a

Evidence of oblate-prolate shape coexistence in the strongly-deformed nucleus 119Cs

Physics Letters B, 2021
Prolate-oblate shape coexistence close to the ground state in the strongly-deformed proton-rich A≈120 nuclei is reported for the first time. One of the four reported bands in 119Cs, built on a 11/2− state at 670 keV, consists of nearly degenerate ...

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

A unified description of the shape phase transition, shape coexistence and mixing phenomena in nuclei [PDF]

EPJ Web of Conferences
The shape phase transition, shape coexistence and mixing phenomena can be described in a unified way within the framework of the phenomenological Bohr-Mottelson model involving a sixth order anharmonic oscillator potential in the intrinsic deformation ...

The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

At the edge of shape coexistence in the Z=40 region [PDF]

EPJ Web of Conferences
In this contribution, the shape coexistence phenomenon near the proton sub-shell closure at Z=40 is analyzed. Particular emphasis is placed on extracting the nuclear deformation values by examining experimental B(E2) transition rates and observing how ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Multiple shape coexistence in the N = Z 84Mo nucleus [PDF]

EPJ Web of Conferences
The structure of the nucleus 84Mo has been studied using the projected generator coordinate method (PGCM) with the Gogny D1S interaction. The calculations incorporate a mixing of particle-number and angular-momentum projected intrinsic wave functions ...
