Nuclear Pairing from Chiral Pion-Nucleon Dynamics: latest results and relevant issues
No full textIn a recent paper [P. Finelli, T. Ni\vksi\`c and D. Vretenar, arXiv:1111.4946] the 1S0 pairing gap in isospin-symmetric nuclear matter and finite nuclei has been investigated starting from the chiral nucleon-nucleon potential at the N3LO order in the two-body sector, and the N2LO order in the three-body sector. To include realistic nuclear forces in RHB (Relativistic Hartree Bolgoliubov) calculations we relied on a separable representation of the pairing interaction. In this paper we would like to show recent results and discuss some issues related to these calculations, in particular how pairing gaps in finite nuclei are sensitive to the choice of ph effective interactions
Developmental disorders with intellectual disability driven by chromatin dysregulation: Clinical overlaps and molecular mechanisms
No full textAdvances in genomic analyses based on next‐generation sequencing and integrated omics approaches, have accelerated in an unprecedented way the discovery of causative genes of developmental delay (DD) and intellectual disability (ID) disorders. Chromatin dysregulation has been recognized as common pathomechanism of mendelian DD/ID syndromes due to mutation in genes encoding chromatin regulators referred as transcriptomopathies or epigenetic disorders. Common to these syndromes are the wide phenotypic breadth and the recognition of groups of distinct syndromes with shared signs besides cognitive impairment, likely mirroring common molecular mechanisms. Disruption of chromatin‐associated transcription machinery accounts for the phenotypic overlap of Cornelia de Lange with KBG and with syndromes of the epigenetic machinery. The genes responsible for Smith‐Magenis‐related disorders act in interconnected networks and the molecular signature of histone acetylation disorders joins Rubinstein‐Taybi‐related syndromes. Deciphering pathway interconnection of clinically similar ID syndromes may enhance search of common targets useful for developing new therapeutics

No full textChiral pion–nucleon dynamics in finite nuclei: Spin–isospin excitations
No full textThe nuclear density functional framework, based on chiral dynamics and the symmetry breaking pattern of low-energy QCD, is extended to the description of collective nuclear excitations. Starting from the relativistic point-coupling Lagrangian introduced in [P. Finelli, N. Kaiser, D. Vretenar, W. Weise, Nucl. Phys. A 770 (2006) 1], the proton–neutron (quasiparticle) random phase approximation is formulated and applied to investigate the role of chiral pion–nucleon dynamics in excitation modes involving spin and isospin degrees of freedom, e.g. isobaric analog states and Gamow–Teller resonances

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
