When tanĂ meets all the mixing angles
Models with two-Higgs-doublets and natural flavour conservation contain as a physical parameter. We offer here a generalization of a recently proposed idea where only the Cabibbo angle, , was related to by virtue of the dihedral symmetry group. The original proposal consisted of a massless first generation of quarks and no mixing with the third generation. In our case, through the addition of a third Higgs doublet with a small vacuum-expectation-value but very large masses, thus later decoupling, all quarks become massive and quark mixing is fully reproduced. In fact, all quark mixing angles are expressed in terms of and one recovers trivial mixing in the limit . We also explore the consequences in lepton mixing by adopting a type I seesaw mechanism with three heavy right-handed neutrinos
Development of a gaze contingent method for auditory threshold evaluation in non-verbal ASD children
Ultra-ductile and low friction epoxy matrix composites
We present the results of an effective reinforcement of epoxy resin matrix
with fullerene carbon soot. The optimal carbon soot addition of 1 wt. % results
in a toughness improvement of almost 20 times. The optimized soot-epoxy
composites also show an increase in tensile elongation of more than 13 %, thus
indicating a change of the failure mechanism in tension from brittle to
ductile. Additionally, the coefficient of friction is reduced from its 0.91
value in plain epoxy resin to 0.15 in the optimized composite. In the optimized
composite, the lateral forces during nanoscratching decrease as much as 80 %
with enhancement of the elastic modulus and hardness by 43 % and 94%,
respectively. The optimized epoxy resin fullerene soot composite can be a
strong candidate for coating applications where toughness, low friction,
ductility and light weight are important.Comment: 24 pages, 7 Figures, 1 Table in Polymer Testing (2015
On the entropy of a stealth vector-tensor black hole
We apply Wald's formalism to a Lagrangian within generalised Proca gravity
that admits a Schwarzschild black hole with a non-trivial vector field. The
resulting entropy differs from that of the same black hole in General
Relativity by a logarithmic correction modulated by the only independent charge
of the vector field. We find conditions on this charge to guarantee that the
entropy is a non-decreasing function of the black hole area, as is the case in
GR. If this requirement is extended to black hole mergers, we find that for
Planck scale black holes, a non-decreasing entropy is possible only if the area
of the final black hole is several times larger than the initial total area of
the merger. Finally, we discuss some implications of the vector Galileon
entropy from the point of view of entropic gravity
