Ecological Responses to Different Degrees of Hydrologic Connectivity: Assessing Patterns in the Bionomy of Benthic Chironomids in a Large River-Floodplain System
(Springer, 2013-06-20)
Floodplain wetlands of the Middle Paraná River, Argentina, are regulated by their hydrologic connectivity to the main channel as well as by their position within the river network. The Chironomids are the most abundant ...
Conformal invariance, complex structures and the Teukolsky connection
(IOP Publishing, 2018-07-23)
We show that the Teukolsky connection, which defines generalized wave operators governing the behavior of massless fields on Einstein spacetimes of Petrov type D, has its origin in a distinguished conformally and GHP ...
Spin connection and renormalization of teleparallel action
(Springer, 2015-10-31)
In general relativity, inertia and gravitation are both included in the Levi-Civita connection. As a consequence, the gravitational action, as well as the corresponding energy-momentum density, are in general contaminated ...
Loop quantization of the Gowdy model with local rotational symmetry
(AMER PHYSICAL SOC, 2017)
We provide a full quantization of the vacuum Gowdy model with local rotational symmetry. We consider a redefinition of the constraints where the Hamiltonian Poisson-commutes with itself. We then apply the canonical ...
Spatial genetic structure in the saddled sea bream (Oblada melanura [Linnaeus, 1758]) suggests multi-scaled patterns of connectivity between protected and unprotected areas in the Western Mediterranean Sea
(2016-04-01)
Marine protected areas (MPAs) and networks of MPAs are advocated worldwide for the achievement of marine conservation objectives. Although the knowledge about population connectivity is considered fundamental for the optimal ...
On the spacetime connecting two aeons in conformal cyclic cosmology
(Springer, 2015-12-01)
As quotient spaces, Minkowski and de Sitter are fundamental, non-gravitational spacetimes for the construction of physical theories. When general relativity is constructed on a de Sitter spacetime, the usual Riemannian ...
Origins of the sympathetic innervation to the nasal-associated lymphoid tissue (NALT): an anatomical substrate for a neuroimmune connection
(Elsevier Science, 2014-11)
The participation of sympathetic nerve fibers in the innervation of the nasal-associated lymphoid tissues (NALT) was investigated in hamsters. Vesicular monoamine transporter 2 (VMAT2), an established sympathetic marker, ...
