Locked Thick Chains

چکیده
We investigate when thick 3D polygonal chains are locked, i.e., have a disconnected configuration space. In particular, we show that thick 4-chains are never locked, and we exhibit a class of locked thick 5-chains whose ratio of maximum edge length to minimum edge length is strictly less than 3 (the best known ratio for nonthick chains).

Passive coherent beam combining of four Yb-doped fiber amplifier chains with injection-locked seed source.
An injection-locked fiber laser is introduced to the passive fiber laser coherent beam combination with all-optical feedback loop. A coherent beam combining system with two-dimensional four Yb-doped fiber amplifier chains is established, and the injection-locked fiber laser works as a switchable seed source. The 1064 nm output laser of the injection-locked fiber laser is extinguished automatica...
متن کاملMyosin light chain phosphorylation facilitates in vivo myosin filament reassembly after mechanical perturbation.
Phosphorylation of the 20-kDa regulatory myosin light chain (MLC) of smooth muscle is known to cause monomeric myosins in solution to self-assemble into thick filaments. The role of MLC phosphorylation in thick filament formation in intact muscle, however, is not clear. It is not known whether the phosphorylation is necessary to initiate thick filament assembly in vivo. Here we show, by using a...
متن کاملRegulation of myosin self-assembly: phosphorylation of Dictyostelium heavy chain inhibits formation of thick filaments.
Dictyostelium myosin is composed of two heavy chains and two pairs of light chains in a 1:1:1 stoichiometry. Myosin purified from amoebae grown in medium containing [32P]phosphate had two of the subunits labeled (0.2-0.3 mol of phosphate per mol of 210,000-dalton heavy chains and approximately 0.1 mol of phosphate per mol of 18,000-dalton light chain). Kinase activities specific for the 210,000...
متن کاملCaenorhabditis elegans Unc-45 Is a Component of Muscle Thick Filaments and Colocalizes with Myosin Heavy Chain B, but Not Myosin Heavy Chain a
In the nematode Caenorhabditis elegans, animals mutant in the gene encoding the protein product of the unc-45 gene (UNC-45) have disorganized muscle thick filaments in body wall muscles. Although UNC-45 contains tetratricopeptide repeats (TPR) as well as limited similarity to fungal proteins, no biochemical role has yet been found. UNC-45 reporters are expressed exclusively in muscle cells, and...
متن کاملSimple analytical method of cavity design for astigmatism-compensated Kerr-lens mode-locked ring lasers and its applications
An analytical method based on a renormalized q parameter for Gaussian-beam propagation and properly matched self-consistent complex q parameters is proposed to aid in the design of arbitrary-astigmatismcompensated Kerr-lens mode-locked ring cavity lasers. The q parameters throughout the ring cavity can be calculated by solution of an algebraically quadratic equation for an arbitrarily thick Ker...
