Coherent transient data-rate conversion and data transformation [PDF]
Optics Letters, 2000 Temporal compressions of optical pulses and pulse trains have been performed by the photon-echo process in Tm-doped YAG at 793 nm. Single-pulse temporal compression by almost a factor of 500 from 10 micros to 22 ns and pulse train compression by a factor of 14 from 5micros to 350 ns with a high-speed frequency-tunable external-cavity diode laser are ...

Estimating herbarium specimen digitization rates: Accounting for human experience
Applications in Plant Sciences, 2021 Premise Herbaria are invaluable sources for understanding the natural world, and in recent years there has been a concerted effort to digitize these collections. To organize such efforts, a method for estimating the necessary labor is desired.

, 2023 When applied to contingency tables, dual scaling and correspondence are mathematically equivalent methods. For the analysis of rating data, however, the methods differ. To a large extent this is due to differences in preprocessing of the data. In particular, in dual scaling, ratings are either transformed to rank order, or to successive category data ...

Solar Neutrino Rates, Spectrum, and its Moments : an MSW Analysis in the Light of Super-Kamiokande Results [PDF]
, 2000 We re-examine MSW solutions of the solar neutrino problem in a two flavor scenario taking (a) the results on total rates and the electron energy spectrum from the 1117-day SuperKamiokande (SK) data and (b) those on total rates from the Chlorine and ...

Long-term remission and biologic persistence rates: 12-year real-world data
Arthritis Research & Therapy, 2021 Background Biologic therapies have greatly improved outcomes in rheumatoid arthritis (RA) and psoriatic arthritis (PsA). Yet, our ability to predict long-term remission and persistence or continuation of therapy remains limited.

Error rate analysis for indoor wireless networks [PDF]
, 1992 An attempt is made to predict the maximum data rates for a typical wireless computer network operating in an indoor frequency-selective environment. To lower the error rates for high-speed data transmission, the impact of techniques such as diversity ...

STRAIN RATES FOR THE SOUTHERN SIBERIAN CRATON DERIVED FROM GPS MEASUREMENTS
Геодинамика и тектонофизика, 2022 This paper presents quantitative estimates of the strain rates for the southern part of the Siberian craton derived from GPS data. The obtained results confirmed the theoretical concept of low strain rates (10–9×year–1) in the intra-platform areas.

Rate of Convergence to Barenblatt Profiles for the Fast Diffusion Equation [PDF]
, 2011 We study the asymptotic behaviour of positive solutions of the Cauchy problem for the fast diffusion equation near the extinction time. We find a continuum of rates of convergence to a self-similar profile.
