Article Abstract
We analyze the large- structure of the baryon-baryon potential derived in the framework of SU(3) chiral perturbation theory up to next-to-leading order including contact interactions as well as one-meson and two-meson exchange diagrams. Moreover, we assess the impact of SU(3) symmetry breaking from a large- perspective and show that the leading order results can successfully be applied to the hyperon-nucleon potential. Our results include a reduction of the number of relevant low-energy constants of the leading order contact interaction from fifteen to three, and we show that consistency is preserved if the / ratio is given by 2/3 and the / ratio for the baryon decuplet-to-octet coupling is given by 2.

A virtually no-cost method is proposed that can compute the correlation energies of general, covalently bonded, organic, and inorganic molecules (including conjugated π-electron systems) with a well-defined dominant Lewis structure at the accuracy of 99.5% of the near-exact values determined by the coupled-cluster singles, doubles, and perturbative triples [CCSD(T)] in the complete-basis-set (CBS) limit. This Correlation Energy Per Bond (CEPB) method assigns a partial correlation energy to each bond type (characterized by the identities of the two atoms forming the bond and its integer bond order) and to a lone pair, regardless of the bond length, bond angle, sp-hybridization, π-electron conjugation, ionicity, noncovalent interactions, etc.

Deinstitutionalization enables the removal of users from asylums with the support of the Psychosocial Care Network (PCN), which is based on the Psychosocial Care Centers (PCCs). One of the current impasses is the emergence of private/religious institutions that are updating the asylum model. In order to analyze what leads to neo-institutionalization in these locations, an ethnographical study was carried out on nine cases in four PCCs of the three PCNs in the city of Rio de Janeiro, through scrutiny of medical records, interviews with the patient, family members, PCC technicians and managers of the asylums per se.

We determine the low-energy constants f_{0}, L_{4}^{r} and L_{5}^{r} of SU(3) chiral perturbation theory from a lattice QCD calculation of the scalar form factors of the pion with fully controlled systematics. Lattice results are computed on a large set of N_{f}=2+1 gauge ensembles covering four lattice spacings a∈[0.049,0.

Following encounter with an unrepaired DNA lesion, replication is halted and can restart downstream of the lesion leading to the formation of a single-stranded DNA (ssDNA) gap. To complete replication, this ssDNA gap is filled in by one of the two lesion tolerance pathways: the error-prone Translesion Synthesis (TLS) or the error-free Homology Directed Gap Repair (HDGR). In the present work, we evidence a role for the RecBC complex distinct from its canonical function in homologous recombination at DNA double strand breaks.
