KHz-rate volumetric voltage imaging of the whole Zebrafish heart
Biophysical Reports, 2022 Fast volumetric imaging is essential for understanding the function of excitable tissues such as those found in the brain and heart. Measuring cardiac voltage transients in tissue volumes is challenging, especially at the high spatial and temporal ...

Constraining the Accretion Rate Onto Sagittarius A* Using Linear Polarization [PDF]
, 2000 Two possible explanations for the low luminosity of the supermassive black hole at the center of our galaxy are (1) an accretion rate of order the canonical Bondi value (roughly 10^{-5} solar masses per year), but a very low radiative efficiency for the ...

Linear Motors Take Center Stage [PDF]
Mechanical Engineering, 1998 Linear motors offer significant advantages over ball screws and rack-and-pinion systems as they can produce high forces without sacrificing speed or precision. Driven by electricity, linear motors provide direct linear motion without the potential complications associated with pneumatic and hydraulic systems, and without mechanical linkages such as ...

Relative Chebyshev centers in normed linear spaces, I
Journal of Approximation Theory, 1980 AbstractLet E be a normed linear space, A a bounded set in E, and G an arbitrary set in E. The relative Chebyshev center of A in G is the set of points in G best approximating A. We have obtained elsewhere general results characterizing the spaces in which the center reduces to a singleton in terms of structural properties related to uniform and strict

Linear magnetoresistance in metals: guiding center diffusion in a smooth random potential [PDF]
, 2015 We predict that guiding center (GC) diffusion yields a linear and non-saturating (transverse) magnetoresistance in 3D metals. Our theory is semi-classical and applies in the regime where the transport time is much greater than the cyclotron period, and ...

Hamiltonian linear type centers of linear plus cubic homogeneous polynomial vector fields
Journal of Differential Equations, 2021 Agraïments: The first author has been supported by AGAUR FI-DGR 2010. The third author has been supported by AGAUR PIV-DGR-2010, FCT grant PTDC/MAT/117106/2010 and through CAMG SD. We provide normal forms and the global phase portraits in the Poincaré disk for all the Hamiltonian non-degenerate centers of linear plus cubic homogeneous planar polynomial

Many-Body Systems and Quantum Chaos: The Multiparticle Quantum Arnol’d Cat
Condensed Matter, 2019 A multi-particle extension of the Arnol’d cat Hamiltonian system is presented, which can serve as a fully dynamical model of decoherence. The behavior of the von Neumann entropy of the reduced density matrix is studied, in time and as a function of the ...
