Sparse image reconstruction for molecular imaging [PDF]
The application that motivates this paper is molecular imaging at the atomic level. When discretized at sub-atomic distances, the volume is inherently sparse. Noiseless measurements from an imaging technology can be modeled by convolution of the image with the system point spread function (psf). Such is the case with magnetic resonance force microscopy

A spatial analysis of physiological changes associated with infection of cotyledons of marrow plants with cucumber mosaic virus [PDF]
Changes in host primary metabolism associated with the compatible interaction between cucumber mosaic virus and cotyledons of the marrow plant (Cucurbita pepo L.) have been localized, first by measuring activities of key enzymes in infected and ...

Stimulated low-frequency Raman scattering in tobacco mosaic virus suspension [PDF]
Laser pulses interaction with tobacco mosaic virus (TMV) in Tris-HCl pH7.5 buffer and in water has been investigated. 20 ns ruby laser pulses have been used for excitation. Spectrum of the light passing through the sample was registered with the help of Fabri-Perot interferometer. In the case of TMV in water we observed in the spectrum only one line of

Packaging of Tobacco Mosaic Virus Subgenomic RNAs by Brome Mosaic Virus Coat Protein Exhibits RNA Controlled Polymorphism [PDF]
The coat protein (CP) of icosahedral Brome mosaic virus (BMV) was expressed from a genetically engineered rod-shape Tobacco mosaic virus. Molecular characterization of the progeny recovered from symptomatic plants revealed that BMV CP selectively ...

In the pathogen infection and host defence equilibrium, plant viruses have evolved to efficiently replicate their genomes, to resist the attack from host defence responses and to avoid causing severe negative effect on growth and metabolism of the hosts.

Molecular Mechanics Simulations and Improved Tight-binding Hamiltonians for Artificial Light Harvesting Systems: Predicting Geometric Distributions, Disorder, and Spectroscopy of Chromophores in a Protein Environment [PDF]
We present molecular mechanics {and spectroscopic} calculations on prototype artificial light harvesting systems consisting of chromophores attached to a tobacco mosaic virus (TMV) protein scaffold. These systems have been synthesized and characterized spectroscopically, but information about the microscopic configurations and geometry of these TMV ...

Ultrafast Collective Excited State Dynamics of a Virus-supported Fluorophore Antenna [PDF]
Radiation brightening was recently observed in a multi-fluorophore-conjugated brome mosaic virus (BMV) particle, at room temperature under pulsed excitation. Based on its nonlinear dependence on the number of fluorophores, the origins of the phenomenon were attributed to a collective relaxation. However, the mechanism remains unknown.

Molecular studies on a complex of potyviruses infecting solanaceous crops, and some specific virus-host interactions [PDF]
This thesis constitutes a comprehensive analysis of the molecular and biological characteristics of three potyviruses (genus Potyvirus, family Potyviridae) naturally occurring in cultivated and wild species of family Solanaceae: Peru tomato virus (PTV ...
