A Neuromorphic Camera for Tracking Passive and Active Matter with Lower Data Throughput

Laser &Photonics Reviews, EarlyView.
The merits of an event‐based camera (EBC) for studies of passive and active matter are demonstrated. It is shown that it is possible to achieve results equivalent to those from an sCMOS camera while reducing data file sizes by up to two orders of magnitude.

The Impact of Quasi-Conformal Curvature Tensor on Warped Product Manifolds

Axioms
This work investigates the effects on the factor manifolds of a singly warped product manifold resulting from the presence of a quasi-conformally flat, quasi-conformally symmetric, or divergence-free quasi-conformal curvature tensor.

Spatially Periodic Solutions for Evolution Anisotropic Variable‐Coefficient Navier–Stokes Equations: II. Serrin‐Type Solutions

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We consider evolution (nonstationary) space‐periodic solutions to the n$$ n $$‐dimensional nonlinear Navier–Stokes equations of anisotropic fluids with the viscosity coefficient tensor variable in space and time and satisfying the relaxed ellipticity condition.

Construction of an A-manifold on a principal torus bundle

, 2012
We construct a new example of an A-manifold, i.e. a Riemannian manifold with a cyclic-parallel Ricci tensor, which can be viewed as a generalization of the Einstein condition.

Construction of an A-manifold on a principal torus bundle

Annales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2013
We construct a new example of an A-manifold, i.e. a Riemannian manifold with cyclic-parallel Ricci tensor. This condition can be viewed as a generalization of the Einstein condition.

Invariant Einstein metrics on generalized flag manifolds of $Sp(n)$ and $SO(2n)$

Boletim da Sociedade Paranaense de Matemática, 2018
It is well known that the Einstein equation on a Riemannian flag manifold $(G/K,g)$ reduces to an algebraic system if $g$ is a $G$-invariant metric. In this paper we obtain explicitly new invariant Einstein metrics on generalized flag manifolds of $Sp(n)$

Unveiling New Perspectives on the Hirota–Maccari System With Multiplicative White Noise

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this study, we delve into the stochastic Hirota–Maccari system, which is subjected to multiplicative noise according to the Itô sense. The stochastic Hirota–Maccari system is significant for its ability to accurately model how stochastic affects nonlinear wave propagation, providing valuable insights into complex systems like fluid dynamics

Total energy conservation for explaining discrepancies between field observations and the traditional thermal energy balance

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Motivated by discrepancies between field observations and the traditional thermal energy balance derived from the first law of thermodynamics, total energy conservation is applied to derive a generalized thermal energy balance for atmospheric applications. Total energy conservation accounts for all forms of energy variation, including kinetic, thermal,

On the topology of conformally compact Einstein 4-manifolds

, 2003
In this paper we study the topology of conformally compact Einstein 4-manifolds. When the conformal infinity has positive Yamabe invariant and the renormalized volume is also positive we show that the conformally compact Einstein 4-manifold will have at ...
