We use precise T-matrix calculations for prolate and oblate spheroids, Chebyshev particles, and spheres cut by a plane to study the evolution of Lorenz-Mie morphology-dependent resonances (MDRs) with increasing asphericity of nearly spherical particles in random orientation. We show that, in the case of spheroids and Chebyshev particles, the deformation of a sphere by as little as one hundredth...

Modified dispersion relations(MDRs) as a manifestation of Lorentz invariance violation, have been appeared in alternative approaches to quantum gravity problem. Loop quantum gravity is one of these approaches which evidently requires modification of dispersion relations. These MDRs will affect the usual formulation of the Compton effect. The purpose of this letter is to incorporate the effects ...

Plasmids comprising transgene insertions in four lines of transgenic mice have been retrieved by plasmid rescue into a set of Escherichia coli strains with mutations in different members of the methylation-dependent restriction system (MDRS). Statistical analysis of plasmid rescue frequencies has revealed that the MDRS loci detect differential modifications of the transgene insertions among mou...

Lorenz±Mie computations of the extinction cross-section for monodisperse spheres show the existence of a very complex structure that includes extremely narrow peaks called morphology-dependent resonances (MDRs). The width and magnitude of the peaks are highly sensitive functions of the size parameter and the refractive index of the sphere. So far the MDRs have been calculated and observed mostl...

The function of microbial MDRs remains a hotly debated subject. Given the very broad substrate specificities of some MDRs, like the RND pumps that can extrude all classes of amphipathic compounds (cationic, neutral, and anionic), it seems difficult to develop a rationale for pinpointing possible natural substrates of these translocases. At the same time, several clues can be used to guide our s...

With the rising prevalence of multiple-antibiotic resistant-bacteria (MDRs) and the lack of development of new antibiotics by the pharmaceutical industries, there is an urgent need to develop novel approaches to combat MDRs, especially Pseudomonas aeruginosa, Escherichia coli and Staphylococcus aureus. Bacteriophage therapy has been applied for decades as a means of treating bacterial infection...

Systematic scan and statistical analysis of loss of heterozygosity (LOH) has been widely used to define chromosomal aberrations in various cancers for cloning of tumor suppressor genes and for development of prognostic markers. However, the establishment of novel strategies is needed, so that the nonrandom but heterogeneous chromosomal aberration data could provide significant insights into our...

In bacteria, multidrug-resistance pumps (MDRs) confer resistance to chemically unrelated amphipathic toxins. A major challenge in developing efficacious antibiotics is identifying antimicrobial compounds that are not rapidly pumped out of bacterial cells. The plant antimicrobial berberine, the active component of the medicinal plants echinacea and golden seal, is a cation that is readily extrud...

OBJECTIVES Classification of data elements (DEs), which is used in clinical documents is challenging, even in across ISO/IEC 11179 compliant clinical metadata registries (MDRs) due to no existence of reliable standard for identifying DEs. We suggest the Clinical Data Element Ontology (CDEO) for unified indexing and retrieval of DEs across MDRs. METHODS The CDEO was developed through harmoniza...
