Homotopy theory of non-symmetric operads, II: Change of base category and left properness
(Mathematical Sciences Publishers, 2014)
We prove, under mild assumptions, that a Quillen equivalence between symmetric monoidal model categories gives rise to a Quillen equivalence between their model categories of (non-symmetric) operads, and also between model ...

Two-dimensional discrete solitons in rotating lattices
(2007)
We introduce a two-dimensional discrete nonlinear Schrödinger (DNLS) equation with self-attractive cubic nonlinearity in a rotating reference frame. The model applies to a Bose-Einstein condensate stirred by a rotating ...

Efecto de retama monosperma sobre el endemismo amenazado Thymus carnosus: luz, agua y patrón de distribución espacial en un sistema costero dunar
(2013-02-21)
Las interacciones planta-planta suponen una parte fundamental de la ecología de las especies vegetales. Conocer los mecanismos subyacentes a las interacciones y la respuesta de las distintas especies a la presencia de otras ...

Low-Power Artifact-Aware ImplantableNeural RecordingMicrosystem for Brain- Machine Interfaces
(2021-06-02)
Neuroscience research into how complex brain functions are implemented at cell level requires in vivo neural recording interfaces, including microelectrodes and read-out circuitry, with increased observability and spatial ...

On the efficient implementation of SDA for boxed strip-like and slot-like structures
(Institute of Electrical and Electronics Engineers, 1998)
This paper reports on an enhanced implementation of the spectral-domain analysis (SDA) of boxed multistrip or multislot transmission lines embedded in a layered medium, including biaxial materials. Very high numerical ...

On the global existence for the Muskat problem
(European Mathematical Society, 2013)
The Muskat problem models the dynamics of the interface between two incompressible immiscible fluids with different constant densities. In this work we prove three results. First we prove an $L^2(\R)$ maximum principle, ...

Comment on “Ratchet universality in the presence of thermal noise”
(2013)
A recent paper [P. J. Martínez and R. Chacón, Phys. Rev. E 87, 062114 (2013)] presents numerical simulations on a system exhibiting directed ratchet transport of a driven overdamped Brownian particle subjected to a spatially ...

The General Set in the MCIM isotopic model
(Springer, 2005)
To obtain a bigger number of mathematical and physical applications of the Santilli's isotheory, the last studies have shown the neeed of analyzing isotopic models which use non associative laws. The main goal of this paper ...

Efficient state reduction methods for PLA-based sequential circuits
(Institute of Electrical and Electronics Engineers, 1992)
Experiences with heuristics for the state reduction of finite-state machines are presented and two new heuristic algorithms described in detail. Results on machines from the literature and from the MCNC benchmark set are ...

ChIP analysis unravels an exceptionally wide distribution of DNA binding sites for the NtcA transcription factor in a heterocyst-forming cyanobacterium
(BioMed Central, 2014)
Background The CRP-family transcription factor NtcA, universally found in cyanobacteria, was initially discovered as a regulator operating N control. It responds to the N regime signaled by the internal 2-oxoglutarate ...
