Understanding molecular interactions at the surfaces of cellular membranes, including adsorption and transport, is of fundamental importance in both biological and pharmaceutical studies. At present, particularly with respect to small and medium size (drug-like) molecules, it is desirable to gain an understanding of the mechanisms that govern membrane adsorption and transport. To characterize drug-membrane interactions and mechanisms governing the process of molecular uptake at cellular membranes in living organisms, we need to develop effective experimental techniques to reach quantitative and time-resolved analysis of molecules at the membrane surfaces. Also, we preferably want to develop label-free optical techniques suited for single-cell and live cell analysis. Here, I discuss the nonlinear optical technique, second-harmonic light scattering (SHS), for studying molecule-membrane interactions and transport of molecules at the membrane of living cells with real-time resolution and membrane surface-specificity. Time-resolved SHS can quantify adsorption and transport of molecules, with specific nonlinear optical properties, at living organisms without imposing any mechanical stress onto the membrane. This label-free and surface-sensitive technique can even differentiate molecular transport at individual membranes within a multi-membrane cell (e.g., bacteria). In this dissertation, I present our current research and accomplishments in extending the capabilities of the SHS technique to study molecular uptake kinetics at the membranes of living cells, to monitor bacteria membrane integrity, to characterize the antibacterial mechanism-of-action of antibiotic compounds, to update the molecular mechanism of the Gram-stain protocol, to pixel-wise mapping of the membrane viscosity of the living cells, and to probe drug-induced activation of bacterial mechanosensitive channels in vitro.

Повний текст джерелаIn terms of computational methods, solving three-dimensional time-harmonic electromagnetic scattering problems is known to be a challenging task, most particularly in the high frequency regime and for dielectric and inhomogeneous scatterers. Indeed, it requires to discretize a system of partial differential equations set in an unbounded domain. In addition, considering a small wavelength λ in this case, naturally requires very fine meshes, and therefore leads to very large number of degrees of freedom. A standard approach consists in combining integral equations for the exterior domain and a weak formulation for the interior domain (the scatterer) resulting in a formulation coupling the Boundary Element Method (BEM) and the Finite Element Method (FEM). Although natural, this approach has some major drawbacks. First, this standard coupling method yields a very large system having a matrix with sparse and dense blocks, which is therefore generally hard to solve and not directly adapted to compression methods. Moreover, it is not possible to easily combine two pre-existing solvers, one FEM solver for the interior domain and one BEM solver for the exterior domain, to construct a global solver for the original problem. In this thesis, we present a well-conditioned weak coupling formulation between the boundary element method and the high-order finite element method, allowing the construction of such a solver. The approach is based on the use of a non-overlapping domain decomposition method involving optimal transmission operators. The associated transmission conditions are constructed through a localization process based on complex rational Padé approximants of the nonlocal Magnetic-to-Electric operators. The number of iterations required to solve this weak coupling is only slightly dependent on the geometry configuration, the frequency, the contrast between the subdomains and the mesh refinement

The objective of this research is to study the scattering of a vertically transversely isotropic cylindrical canyon subjected to the incidence of time harmonic plane elastic wave. The total displacement field of either the anti-plane or in-plane scattering problem can be decomposed into two parts, namely, free field as well as scattering filed part. The known free field part can be further separated into incident wave and reflected wave in order to satisfy the ground surface condition. While the unknown scattering field part is expanded into a series of n-th order outgoing singular solutions of Lamb’s problem with unknown amplitude which can be determined by boundary condition of canyon itself. The displacement field and stress field of each n-th order outgoing singular solutions of Lamb’s problem can only be expressed into a form of horizontal wave-number integral which can be evaluated efficiently in complex wave-number domain by using the so called steepest descend-stationary phase method. For in-plane scattering problem, the outgoing scattering field contains two kinds of wave field, namely, P wave and S wave, only two sheets of the four Riemann Surface are sufficient to describe the outgoing scattering field. In order to ensure the single value of a multi-value radical function in each Riemann sheet, the branch points and the associated branch cuts are carefully chosen according to the material considered. Least Square method is employed to solve the unknown coefficients of the expansion series of the scattering field. Once the coefficients are determined, the complete displacement field and stress field can be obtained.

The objectives of this thesis is aim to study the scattering as well as the dynamic stress concentration phenomenon of a vertically transversely isotropic special oblate elliptic cylindrical cavity subjected to the obliquely incidence of time harmonic plane elastic wave. An incident plane wave field traveling through three different types of exterior medium then impinging onto a special oblate elliptic cylindrical cavity with certain specific aspect ratio. There will have different solution strategies according to different types of material property. Since the slowness surface for Magnesium is a circle, therefore, the original scattering problem needs not be converted in geometry. We use the classical cylindrical wave function to solve the corresponding scattering problem, directly. However, for Beryllium and Zinc , since their dimensionless material constant are not equal to 1, therefore, both the slowness surface of these two types of material are ellipse. In order to solve the corresponding scattering problem, firstly, we convert the original elliptical slowness surface for a transverse isotropic material into a circular slowness surface for an isotropic material. At the same time, the geometry of the original problem have been converted from a special oblate elliptical cavity into a circular cavity. In this thesis, two methods are used to solve the corresponding problem, namely, the separation of variable method as well as the discrete boundary collocation point method. We first use the separation of variable method to separate the classical wave function into the product of a Hankel function and a trigonometric function in classical cylindrical coordinate system, and then use the boundary condition of the circular cavity to solve the unknown scattering coefficients. Another alternative method is boundary collocation point method, we propose that after the transformation, the unknown scattering field part can be expanded into a series of n-th order wave function. Each wave function is defined by a trigonometric function angular spectrum along a complex contour integral path with a kernel function which is non-trivial plane wave solution of the corresponding wave equation. The trigonometric angular spectrum of each n-th order wave function can be further converted into an infinite horizontal slowness integral which can be evaluated efficiently in complex slowness domain by employing the steepest descend-stationary phase method. In order to satisfy the boundary condition at each boundary collocation point which allocate along the cavity surface, Least Square method is employed to obtain the unknown coefficient of the expansion series of the scattering field. Thus, the dynamic stress concentration phenomenon of a vertically transversely isotropic special oblate elliptic cylindrical cavity subjected to the obliquely incidence of time harmonic plane elastic wave is thoroughly studied by both of the proposed methods for three different typical materials.
