Toda solitons as Fermi-quasiparticles

The Bethe ansatz leads to Yang-Yang integral equations. The particle-hole structure of the zero-temperature excitations is generalized to finite temperatures, which leads to the definition of soliton- and phonon-quasiparticles. The solitons approximately follow the Fermi-Dirac statistics and have a chemical potential with an unusual temperature dependence, because the number of solitons is not constant.     

Multichip vertical-external-cavity surface-emitting lasers: a coherent power scaling scheme

We propose an efficient coherent power scaling scheme, the multichip vertical-external-cavity surface-emitting laser (VECSEL), in which the waste heat generated in the active region is distributed on multi-VECSEL chips such that the pump level at the thermal rollover is significantly increased. The advantages of this laser are discussed, and the development and demonstration of a two-chip VECSEL operating around 970 nm with over 19 W of output power is presented.     

EFFECTS OF SOLAR RADIATION ON DEVELOPMENT IN THE CELLULAR SLIME MOLD, Dictyostelium discoideum

–The effect of solar radiation on development was studied in two strains (wild type N04 and axenic AX2) of the cellular slime mold, Dictyostelium discoideum. In both strains early development was retarded by solar radiation and amoebae exposed for >200 min never developed into mature sorocarps. Overheating can be excluded as a mechanism for inhibition since the organisms were exposed in a temperature-controlled growth chamber. The most effective component seems to be UV-B radiation (while UV-A has a smaller inhibitory effect) as shown by cutting off shorter wavelength radiation using WG filters.     

Cyclic and Lasso Peptides: Sequence Determination,Topology Analysis,and Rotaxane Formation

A broadly applicable chemical cleavage methodology to facilitate MS/MS sequencing was developed for macrocyclic and lasso peptides, which hold promise as exciting new therapeutics. Existing methods such as Edman degradation, CNBr cleavage, and enzymatic digestion are either limited in scope or completely fail in cleavage of constrained nonribosomal peptides. Importantly, the new method was utilized for synthesizing a unique peptide‐based rotaxane (both cyclic and threaded) from the lasso peptide, benenodin‐1 ΔC5.     

Compatibility criterion for quadripotents in Jordan quadruple systems

We extend the notion of compatibility of tripotents in a Jordan triple system to that of quadripotents in a Jordan quadruple system and get a criterion for compatibility of quadripotents in a Jordan quadruple system.     

Mound morphology and growth dynamic of the wedding-cake interfaces

We aimed in this work to study numerically the scaling behavior and the mound morphological properties of the interfaces generated by the multilayer deposition process. We have found that when the diffusion process dominates strongly the deposition one, the obtained interfaces consist of wedding-cake like structures. The width of the surface is a self-affine fractal exhibiting non-trivial scaling with the surface height and the system size, and the obtained interfaces follow the Family–Vicsek law with exponent values more consisting with the Edwards–Wilkinson model.     

Effect of thermal losses on the microscopic hyperbolic heat conduction model

The effects of radiative losses on the thermal behavior of thin metal films, as described by the microscopic two-step hyperbolic heat conduction model, are investigated. Different criteria, which determine the ranges within which thermal radiative losses are significant, are derived. It is found that radiative losses from the electron gas are significant in thin films having [(C_R e_e^4/₃ T_￥ ⁴ )/(k_e^1/₃ L^2/₃ G)] 3 4.6 ×10⁷{{C_R \epsilon _e^{{4 \over 3}} T_\infty ^4 } \over {k_e^{{1 \over 3}} L^{{2 \over 3}} G}}\geq 4.6 \times 10^7 for /_o > 4 and F_F < 1 and [(C_R e_e^3/₂ T_￥ ^9/₂)/(k_e^1/₂ L^1/₂ G)] 3 7.4 ×10¹⁰{{C_R \epsilon _e^{{3 \over 2}} T_\infty ^{{9 \over 2}}} \over {k_e^{{1 \over 2}} L^{{1 \over 2}} G}}\geq 7.4 \times 10^{10} for /_o < 4 and F_F > 1.
