On meson dominance in the `second class' tau \to eta pi nu_tau decay [PDF]
Phys.Rev.D82:057301,2010, 2010 Motivated by recent estimates of the isospin-violating process tau \to eta pi nu_tau, mostly relying on the rho and a_0 dominance of the relevant form factors near threshold, we present an assessment for the branching ratio that accounts for additional, potential, effects from the lowest radial excitations rho(1450) and a_0(1450), respectively, also ...

DDVCS on nucleons and nuclei [PDF]
Phys.Rev.D82:014017,2010, 2010 In this paper we evaluate the double deeply virtual Compton scattering on nucleons and nuclei in the framework of the color dipole model. Both the effects of quark and the gluon shadowing are taken into account.

From twistors to twisted geometries [PDF]
Phys.Rev.D82:084041,2010, 2010 In a previous paper we showed that the phase space of loop quantum gravity on a fixed graph can be parametrized in terms of twisted geometries, quantities describing the intrinsic and extrinsic discrete geometry of a cellular decomposition dual to the graph. Here we unravel the origin of the phase space from a geometric interpretation of twistors.

The Good News-Bad News Effect: Asymmetric Processing of Objective Information about Yourself
, 2011 We study processing and acquisition of objective information regarding qualities that people care about, intelligence and beauty. Subjects receiving negative feedback did not respect the strength of these signals, were far less predictable in their ...

The Clinical Teacher, Volume 22, Issue 1, February 2025.ABSTRACT Introduction As the delivery of continuing medical education moves towards digital modes, determining how to embed and capitalise on the skills of specialised educators in digital modalities is critical. Drawing on social theories of adult learning and behaviour change, this study trialled multiple delivery modes of education about ...

Nucleon Statistics in Holographic QCD : Aharonov-Bohm Effect in a Matrix Model [PDF]
Phys.Rev.D82:105023,2010, 2010 We show that the Aharonov-Bohm effect in the nuclear matrix model derives the statistical nature of nucleons in holographic QCD. For N_c= odd (even), the nucleon is shown to be a fermion (boson).

The Plant Journal, Volume 121, Issue 4, February 2025.SUMMARY Mitochondrial complex I (CI), a large multi‐subunit respiratory complex contains two LYR (leucine/tyrosine/arginine) domain‐containing subunits, B14 (NDUA6/LYRM6) and B22 (NDUB9/LYRM3). Mitochondrial LYR (LYRM) proteins are soluble matrix‐located proteins that have been implicated in diverse functions such as iron–sulphur cluster insertion ...
