Modulational-instability-free pulse compression in anti-resonant hollow-core photonic crystal fiber

, 2020
Gas-filled hollow-core photonic crystal fiber (PCF) is used for efficient nonlinear temporal compression of femtosecond laser pulses, two main schemes being direct soliton-effect self-compression, and spectral broadening followed by phase compensation ...

Intersection theory and the Horn inequalities for invariant subspaces [PDF]

, 2015
We provide a direct, intersection theoretic, argument that the Jordan models of an operator of class C_{0}, of its restriction to an invariant subspace, and of its compression to the orthogonal complement, satisfy a multiplicative form of the Horn ...

Phase Transition in Strongly Degenerate Hydrogen Plasma [PDF]

, 2001
Direct fermionic path-integral Monte-Carlo simulations of strongly coupled hydrogen are presented. Our results show evidence for the hypothetical plasma phase transition.

An experimental study of the dual-fuel performance of a small compression ignition diesel engine operating with three gaseous fuels [PDF]

, 2007
A dual-fuel engine is a compression ignition (CI) engine where the primary gaseous fuel source is premixed with air as it enters the combustion chamber.

Source coding by efficient selection of ground states clusters [PDF]

, 2004
In this letter, we show how the Survey Propagation algorithm can be generalized to include external forcing messages, and used to address selectively an exponential number of glassy ground states. These capabilities can be used to explore efficiently the

Comparative analysis of co-processed starches prepared by three different methods

British Journal of Pharmacy, 2017
Co-processing is currently of interest in the generation of high-functionality excipients for tablet formulation. In the present study, comparative analysis of the powder and tableting properties of three co-processed starches prepared by three different
