Chloroplast nucleoids are highly dynamic in ploidy, number, and structure during angiosperm leaf development

The Plant Journal, Volume 102, Issue 4, Page 730-746, May 2020., 2020
Summary Chloroplast nucleoids are large, compact nucleoprotein structures containing multiple copies of the plastid genome. Studies on structural and quantitative changes of plastid DNA (ptDNA) during leaf development are scarce and have produced controversial data.

Progress in Understanding the Nuclear Equation of State at the Quark Level [PDF]

, 2007
At the present time there is a lively debate within the nuclear community concerning the relevance of quark degrees of freedom in understanding nuclear structure.

Convergence of nuclear effective field theory with perturbative pions [PDF]

, 2019
The classic paper by Fleming, Mehen, and Stewart (FMS) [Nucl. Phys. A 677, 313 (2000)] cast doubts on the convergence of spin-triplet nucleon-nucleon partial wave scattering amplitudes when following the proposal of Kaplan, Savage, and Wise to construct ...

Reevaluation of the nuclear electric quadrupole moment for Sr87 by hyperfine structures and relativistic atomic theory [PDF]

Physical Review A, 2019
The values of nuclear electric quadrupole moment are different by about 7% for 87Sr nucleus between the recommended value [N. J. Stone, At. Data Nucl. Data Tables 111-112, 1 (2016); P. Pyykko, Mol. Phys. 116, 1328 (2018)] and earlier results [e.g. A.

A Higher-Order Calculation of $np$ Scattering in Cut-Off Effective Field Theory [PDF]

, 1999
We report a next-to-leading-order (NLO) chiral perturbation theory calculation of the neutron-proton scattering cross section in the ${}^1S_0$ channel using a cut-off regularization.

Chiral symmetry in nuclei [PDF]

, 1999
Effective field theory is considered to provide a highly useful framework for connecting nuclear physics with the symmetries and dynamics of the underlying theory of strong interactions, QCD.

On a Missed Mechanism of Dielectron Production in Nucleon-Nucleon Collisions

, 2010
We examine a new mechanism of $e^+e^-$ pair production in $NN$ collisions associated with the $NN$-decoupled dibaryon $d^\star_1$(1956) formation in the process $NN \to \gamma^\star d^\star_1$, where $\gamma^\star$ is the virtual photon which converts ...

Relativistic hydrodynamics in heavy-ion collisions: general aspects and recent developments [PDF]

, 2016
Relativistic hydrodynamics has been quite successful in explaining the collective behaviour of the QCD matter produced in high energy heavy-ion collisions at RHIC and LHC.

Scaling within the Spectral Function approach

, 2017
Scaling features of the nuclear electromagnetic response functions unveil aspects of nuclear dynamics that are crucial for interpretating neutrino- and electron-scattering data. In the large momentum-transfer regime, the nucleon-density response function
