A novel R-matrix formalism for three-body channels [PDF]
EPJ Web of Conferences, 2023 At low incident neutron energies nuclear reaction cross sections exhibit a distinct resonance structure which cannot properly be described by (semi-)microscopic models.

Genomic cis-acting Sequences Improve Expression and Establishment of a Nonviral Vector
Molecular Therapy: Nucleic Acids, 2013 The vector pEPI was the first nonviral and episomally replicating vector. Its functional element is an expression unit linked to a chromosomal scaffold/matrix attached region (S/MAR).

Threshold effects in the 10B(p,α)7Be, 12C(p,γ)13N and 14N(p,γ)15O reactions
Frontiers in Physics, 2022 The typical energy range for charge particle interactions in stellar plasmas corresponds to a few 10s or 100s of keV. At these low energies, the cross sections are so vanishingly small that they cannot be measured directly with accelerator based ...

Drosophila SAF-B links the nuclear matrix, chromosomes, and transcriptional activity. [PDF]
PLoS ONE, 2010 Induction of gene expression is correlated with alterations in nuclear organization, including proximity to other active genes, to the nuclear cortex, and to cytologically distinct domains of the nucleus. Chromosomes are tethered to the insoluble nuclear

Function of the Sperm Nuclear Matrix [PDF]
Archives of Andrology, 2007 Mammalian spermatozoa contain some of the most highly compact chromatin. This is due to the DNA binding proteins, the protamines, which replace most of the histones during spermiogenesis. This chromatin, however, shares some features with somatic cell chromatin.

Low-rank matrix decompositions for ab initio nuclear structure
Physics Letters B, 2021 The extension of ab initio quantum many-body theory to higher accuracy and larger systems is intrinsically limited by the handling of large data objects in form of wave-function expansions and/or many-body operators.

Half a Century of “The Nuclear Matrix” [PDF]
Molecular Biology of the Cell, 2000 A cell fraction that would today be termed “the nuclear matrix” was first described and patented in 1948 by Russian investigators. In 1974 this fraction was rediscovered and promoted as a fundamental organizing principle of eukaryotic gene expression.

Effective R-Matrix Parameterizations for Nuclear Data* [PDF]
EPJ Web of ConferencesWe derive an effective Reich-Moore approximation (RMA) of the Wigner-Eisenbud R-matrix formalism parameterized by complex-valued resonance energies and widths; this RMA exactly reproduces the total eliminated cross section.

Nuclear Matrix Elements for Heavy Ion Sequential Double Charge Exchange Reactions
Universe, 2021 The theoretical approach to a sequential heavy ion double charge exchange reaction is presented. A brief introduction into the formal theory of second-order nuclear reactions and their application to Double Single Charge Exchange (DSCE) reactions by ...
