We have recently described the immunosuppressive properties of AR-C117977 and AR-C122982, representatives of a group of compounds identified as inhibitors of lactate transporters (monocarboxylate transporters; MCTs). These compounds demonstrate the p

The polarization states in a figure and laser are analyzed using Jones matrices. The analysis shows that a figure-8 laser in CW operation does not give enough information to allow the optimization of the birefringence for mode-locking. A switchable n

Coherent optical implementations of the FMCW technique [1] depend on the interferometric mixing of an optical signal probing the network under test with a reference signal obtained from the same source, whose carrier frequency is linearly, and phase-

A long-coherence-length, diode-pumped, monolithic Nd:YAG laser operating at 1.32 mu m is used to perform coherent FMCW (frequency-modulated continuous wave) reflectometry measurements. Compared with semiconductor-based lasers, the low phase noise of

Characterization of short optical pulses, such as occur in high speed optical communication systems, is currently performed using electronic instrumentation of limited bandwidth.

Recently reported model experiments of Knapp [1] on electroded cascade development provide an excellent set. of data for testing presumptive development models since so many of the experimental parameters are available. A development model is present

An optical receiver front end was built which detects optical heterodyne signals up to 80 GHz. The unit combines optical detection in a GaAs photodiode with RF mixing of that same detected signal in the same photodiode. At low frequencies the diode i

As the bandwidth of optical modulators increases, it becomes more difficult to measure their frequency response. A number of methods are currently in use, including direct detection using a fast, calibrated photodiode [1], the a.m. sideband technique
