We analyze the combined effects of aquifer heterogeneity and pumping operations on seawater intrusion (SWI) in coastal aquifers, a phenomenon which is threatening Mediterranean and worldwide regions. We conceptualize the aquifer as a three-dimensional randomly heterogeneous porous medium, where the spatial distribution of permeability is uncertain. The geological setting of our study is pattern...

A set of simulated high-resolution infrared (IR) emission spectra of synthetic cirrus clouds is used to perform a sensitivity analysis of top-of-atmosphere (TOA) radiance to cloud parameters. Principal component analysis (PCA) is applied to assess the variability of radiance across the spectrum with respect to microphysical and bulk cloud quantities. These quantities include particle shape, eff...

The Sliding Window Lempel-Ziv (SWLZ) algorithm that makes use of recurrence times and match lengths has been studied from various perspectives in information theory literature. In this paper, we undertake a finer study of these quantities under two different scenarios, i) zero entropy sources that are characterized by strong long-term memory, and ii) the processes with weak memory as described ...

Knowledge of protein structure provides essential insight into function, enhancing our understanding of diseases and enabling new treatment development. X-ray crystallography has been used to solve the structures of more than 100 000 proteins; however, the vast majority represent long-lived states that do not capture the functional motions of these molecular machines. Reactions triggered by the...

A method employing Bayesian statistics is used to incorporate recent experimental results on B0dB̄ 0 d and B 0 s B̄ 0 s mixing into a measurement of the Cabibbo-Kobayashi-Maskawa matrix elements with small theoretical uncertainties. The neutral B meson mixing results yield a slight improvement in the estimate of |Vtd|. Prospects for improving the knowledge of the CKM matrix elements with measurem...

Abstract Environmental perturbations and noise are source of mode mixing interferences between the propagating modes a complex multi-mode fiber. Typically, they characterized by their correlation (paraxial) length, spectral content which describes degree coupling various modes. We show that an appropriate control these quantities allows to engineer Levy-type relaxation processes initial excitat...

Using Dirac equation together with the Wigner distribution function,the trembling motion,known as Zitterbewegung effect,of moving electrons in quasi-one-dimensional relativistic quantum plasma is theoretically investigated.The matrix used to calculate mean values of position and velocity operators for a gas electrons.It found that oscillatory behavior measurable quantities could be associated e...

We update the Standard-Model predictions for several quantities related to Bs−Bs and Bd−Bd mixing. The mass and width differences in the Bs system read ∆M SM s = (17.3 ± 2.6) ps and ∆Γ s = (0.087 ± 0.021) ps, respectively. The CP asymmetries in flavour-specific decays are a fs = (1.9±0.3)·10−5 and a d,SM fs = −(4.1±0.6)·10−4. We further critically discuss the sensitivity of ∆Γd to new physics a...

Early mathematical representations of infectious disease dynamics assumed a single, large, homogeneously mixing population. Over the past decade there has been growing interest in models consisting of multiple smaller subpopulations (households, workplaces, schools, communities), with the natural assumption of strong homogeneous mixing within each subpopulation, and weaker transmission between ...

gas mixing in a t-shape micro mixer has been simulated using the direct simulation monte carlo (dsmc) method. it is considered that the adequate mixing occurs when the mass composition of the species, co or n2, deviates below 1 % from their equilibrium composition. the mixing coefficient is defined as the ratio of the mixing length to the main channel’s height. as the inlet kn increases, while ...
