Regularization estimates and Cauchy theory for inhomogeneous Boltzmann equation for hard potentials without cut-off
... Let us underline the fact that Theorem 1.1 largely improves previous results on the Cauchy theory associated to the Boltzmann equation without cut-off for hard potentials in a perturbative setting. Indeed, ...

Exponential convergence to equilibrium for the homogeneous Boltzmann equation for hard potentials without cut-off
... where λ > 0 is defined in Theorem 1.4. We improve a polynomial result of Villani [40] and generalize to our context similar exponential results known for simplified models. Mouhot in [32] proved such a result for the ...

Defining reference interval of haemoglobin in early postpartum: the actual cut-off for postpartum anaemia
... Despite the few data existing in literature, the results were comparable to other studies. Low haemoglobin reference interval agrees with Breymann 2010 who mentions that the nadir of postpartum haemoglobin levels is ...

Evaluating suggested lengths used for cut-off planes using the effective length calculation procedure
... There are different methods being used to quantify the thermal performance of building assemblies, including but not limited to, hand calculations (ASHRAE, 2017) (National Research Council Canada, 2011), Guarded Hot Box ...

Analysis of the acoustic cut-off frequency and high-frequency peaks in six Kepler stars with stochastically excited pulsations
... Gravito-acoustic modes in the Sun and other stars propagate in resonant cavities with a frequency below a given limit known as the cut-o ff frequency. At higher frequencies, waves are no longer trapped in the ...

From Newton's law to the linear Boltzmann equation without cut-off
... A huge number of microscopic contexts has been investigated (see the book by Spohn [ 16 ] for a survey on this topic). What we intend to do here is to obtain a complete derivation of the linear Boltzmann equation without ...

Implementation of long-wavelength cut-off filters based on critical angle
... infrared cut-off filters with extended transmis- sion and rejection regions that are based on the use of the critical angle, the dispersion of refractive indices, and on thin-film interference were not very ...

Confinement and cut-off: A model for the Pion Quark Distribution Function
... The pion structure function is investigated in a simple pseudo-scalar coupling model of pion and constituent quark fields. The imaginary part of the forward Compton scattering amplitude is evaluated. We show that the ...
