Signal mixer for optical heterodyne receiver
Incoming signal is mixed with local oscillator signal by a beam splitter inside laser cavity. Laser power can be reduced by 50 to 100 times
Stress corrosion crack inhibiting method for titanium
Addition of oxyanions to liquid solvents in excess of the number of chloride, bromide, or iodide ions present prevents cracking of titanium-aluminum alloys under exposure to aqueous and other solvent environments. The molar concentration of oxyanion is set from 10 to 100 times higher than concentration of halide ions
The lambda Phi^4 Miracle: lattice data and the zero-point potential
Recent lattice data for the effective potential of lambda Phi^4 theory fits
the massless one-loop formula with amazing precision. Any corrections are at
least 100 times smaller than is reasonable, perturbatively. This is strong
evidence for the "exactness conjecture" of Consoli and Stevenson.Comment: 6 pages, LaTe
Rapid method for interconversion of binary and decimal numbers
Decoding tree consisting of 40-bit semiconductor read-only memories interconverts binary and decimal numbers 50 to 100 times faster than current methods. Decimal-to-binary conversion algorithm is based on a divided-by-2 iterative equation, binary-to-decimal conversion algorithm utilizes multiplied-by-2 iterative equation
Replica-exchange molecular dynamics simulation for supercooled liquids
We investigate to what extend the replica-exchange Monte Carlo method is able
to equilibrate a simple liquid in its supercooled state. We find that this
method does indeed allow to generate accurately the canonical distribution
function even at low temperatures and that its efficiency is about 10-100 times
higher than the usual canonical molecular dynamics simulation.Comment: 6 pages, 5 figure
Super B Factories
Heavy-flavor physics, in particular B and τ physics results from the B factories, currently provides strong constraints on models of physics beyond the Standard Model. A new generation of colliders, Super B Factories, with 50 to 100 times the luminosity of existing colliders, can, in a dialog with LHC and ILC, provide unique clarification of new physics phenomena seen at those machines
First-principles method for high- photonic crystal cavity mode calculations
We present a first-principles method to compute radiation properties of
ultra-high quality factor photonic crystal cavities. Our Frequency-domain
Approach for Radiation (FAR) can compute the far-field radiation pattern and
quality factor of cavity modes times more rapidly than conventional
finite-difference time domain calculations. It also provides a simple rule for
engineering the cavity's far-field radiation pattern
