The Journal of Cell Biology, 1972 The subunit organization of the myosin filament of chicken striated muscle has been observed directly in cross-sections in electron microscopy. The organization consists of three centrally located and nine peripherally located subunits in a close-packed arrangement.

Filamentation in low pressure conditions
Scientific Reports, 2022 Filamentation is favorable for many long-range outdoor laser applications, some of which require propagation to or at high altitudes. Understanding how the filamentation process and filament properties are impacted by the low pressure conditions present ...

Advanced Science, 2023 AbstractFreestanding slender fluid filaments of room‐temperature ferroelectric nematic liquid crystals are described. They are stabilized either by internal electric fields of bound charges formed due to polarization splay or by external voltage applied between suspending wires.

Photonic crystals for suppression of filamentation
, 2022 In this work we show the prospect of using periodic refractive index modulation – photonic crystals – to control the spatial dispersion curvature in a way that could potentially counteract the Kerr effect, thus suppressing filamentation.

Bypass of Dfi1 Regulation of Candida albicans Invasive Filamentation by Iron Limitation
mSphere, 2022 Candida albicans filamentation, the ability to convert from oval yeast cells to elongated hyphal cells, is a key factor in its pathogenesis. Previous work has shown that the integral membrane protein Dfi1 is required for filamentation in cells grown in ...

Lighting the Universe with Filaments [PDF]
Science, 2007 The first stars in the universe form when chemically pristine gas heats as it falls into dark-matter potential wells, cools radiatively because of the formation of molecular hydrogen, and becomes self-gravitating. Using supercomputer simulations, we demonstrated that the stars' properties depend critically on the currently unknown nature ...

Polarization-Sensitive Nonlinear Optical Interaction of Ultrashort Laser Pulses with HPHT Diamond
Photonics, 2023 The filamentation of focused 300 fs laser pulses with variable polarization azimuth in bulk of synthetic HPHT diamond demonstrates the possibility of polarization-dependent bandgap control for crystal dielectric photoexcitation. This directly affects the

Filamentation of Femtosecond Vector Beams
, 2023 We numerically study the filamentation of femtosecond vector beams with spatially varying polarization profiles in air. The vector beams include azimuthal, radial, and spiral cylindrical vector beams (CVBs), as well as low-order full Poincar\'e beams ...
