Semiflexible Filamentous Composites [PDF]
Physical Review Letters, 2010 Inspired by the ubiquity of composite filamentous networks in nature we investigate models of biopolymer networks that consist of interconnected floppy and stiff filaments. Numerical simulations carried out in three dimensions allow us to explore the microscopic partitioning of stresses and strains between the stiff and floppy fractions c_s and c_f ...

Crystal Structure of the Escherichia coli Fic Toxin-Like Protein in Complex with Its Cognate Antitoxin [PDF]
, 2016 FIC domain proteins mediate post-translational modifications of target proteins, which typically results in their inactivation. Depending on the conservation of crucial active site residues, the FIC fold serves as structural scaffold for various ...

Femtosecond filamentation by intensity clamping at a Freeman resonance [PDF]
, 2014 We demonstrate that Freeman resonances have a strong impact on the nonlinear optical response in femtosecond filaments. These resonances decrease the transient refractive index within a narrow intensity window and strongly affect the filamentation ...

Microbiology Spectrum, 2016 ABSTRACTFilamentous mycoses are often associated with significant morbidity and mortality. Prompt diagnosis and aggressive treatment are essential for good clinical outcomes in immunocompromised patients. The host immune response plays an essential role in determining the course of exposure to potential fungal pathogens.

Metabolic and Morphotypic Trade-Offs within the Eco-Evolutionary Dynamics of Escherichia coli
Microbiology Spectrum, 2022 Escherichia coli arbitrarily encompasses facultative anaerobic, rod-shaped bacteria with defined respiratory and fermentative types of metabolism. The species diversification has been further advanced by atypical strains whose features deviate from the ...

BMC Genomics, 2018 Background Bacterial filamentation occurs when rod-shaped bacteria grow without dividing. To identify genetically encoded inhibitors of division that promote filamentation, we used cell sorting flow cytometry to enrich filamentous clones from an ...

Microbiology Spectrum, 2023 While endocytic and secretory pathways are well-studied cellular processes in the model yeast Saccharomyces cerevisiae, they remain understudied in the opportunistic fungal pathogen Candida albicans. We previously found that null mutants of C.

Femtosecond laser filamentation and applications
, 2021 International audienceFemtosecond filamentation is a spectacular phenomenon whereby a short laser pulse propagates nonlinearly through a transparent medium allowing high peak light intensities to be transferred over distances far exceeding the beam ...

Multiple filamentation Ti:Sapphire-laser pulses in water
, 2020 The results of experimental studies of the spatial characteristics of multiple filamentation terawatt femtosecond Ti:Salaser in water are presented. With an increase in initial power laser pulses increases the number of filaments, the length of the field
