UNCLONABLE KEY SEBASTIANUS A. GOORDEN, MARCEL HORSTMANN, ALLARD P. MOSK, BORIS ŠKORIĆ, AND PEPIJN W.H. PINKSE Complex Photonic Systems (COPS), MESA+ Institute for Nanotechnology, University of Twente, PO Box 217, 7500 AE Enschede, The Netherlands Laser Physics and Nonlinear Optics (LPNO), MESA+ Institute for Nanotechnology, University of Twente, PO Box 217, 7500 AE Enschede, The Netherlands Ein...
are maintained. If the etching depth is equal to an integral number of half-wavelengths, uniformly high reflectivity across the active L. Fan, M.C. Wu, H.C. Lee and P. Grodzinski . mesa is achieved. The top electrodes which simultaneously pump the phase-shifted and non-phase-shifted region are then deposited by evaporation and lift-off processes. Fig. 2 shows the scanning electron micrograph (S...
The nasal type of extranodal natural killer/T-cell lymphoma is a rare aggressive lymphoma with poor prognosis. To discover a successful treatment, we investigated the efficacy and safety of chemotherapy with methotrexate, etoposide, dexamethasone, and polyethylene glycol-asparaginase (MESA). Three cycles of MESA were administered to 46 patients with new or relapsed/refractory natural killer/T-c...
There is an array of numerical techniques available to estimate the period of circadian and other biological rhythms. Criteria for choosing a method include accuracy of period measurement, resolution of signal embedded in noise or of multiple periodicities, and sensitivity to the presence of weak rhythms and robustness in the presence of stochastic noise. Maximum Entropy Spectral Analysis (MESA...
The present generation of accelerated PC graphics adapters are capable rendering complex 3-D scenes in real-time. However, software support for these adapters has been slow to evolve in Linux. In this paper we describe our experiences in developing a software system that provides accelerated graphics support to the Mesa graphics library. The performance of accelerated Mesa is compared with that...
Thermal effects are already important in currently operating interferometric gravitational wave detectors. Planned upgrades of these detectors involve increasing optical power to combat quantum shot noise. We consider the ramifications of this increased power for one particular class of laser beams— wide, flat-topped, mesa beams. In particular we model a single mesa beam Fabry–Perot cavity havi...

We have examined the optical properties of self-assembled InAs quantum dots ~QDs! grown on prepatterned GaAs~001! substrates with polarization sensitive and time-resolved cathodoluminescence ~CL! imaging and spectroscopy techniques. The InAs QDs were formed using a novel application in self-assembled molecular beam epitaxial growth, which entailed the growth of InAs on preformed @11̄0#-oriented ...
