The Financial Crisis of A. D. 33: A Keynesian Depression?
Autor: M. K. Thornton, R. L. Thornton
Publikováno v: The Journal of Economic History. 50:655-662
In A.D. 33 a major economic and financial crisis struck the City of Rome, capital of the Roman Empire.' The crisis must have made a tremendous impression on the world at the time; otherwise, the three great historians of the period (Tacitus, Suetoniu

Achievement of high gain in a multiple quantum channel lateral heterojunction bipolar transistor
Autor: W. J. Mosby, H. F. Chung, R. L. Thornton
Publikováno v: Applied Physics Letters. 56:1670-1672
We describe refinements in the geometry of a lateral heterojunction bipolar transistor that have allowed us to greatly improve the dc characteristics of these devices. By reducing the base dimensions to 0.35 μm and improving the abruptness of the gr

Ultrafast Phenomena VIII
Semiconductors have recently been shown to be useful as saturable absorbers. Both bulk and quantum well materials have been used to generate picosecond and femtosecond pulses in color center[1], erbium-doped fiber[2], dye[3] and semiconductor[4] lase

Benefits of intrawaveguide saturable absorbers in external cavity mode-locked semiconductor lasers
Autor: D. J. Derickson, R. J. Helkey, A. Mar, R. L. Thornton, J. E. Bowers
Publikováno v: Optical Society of America Annual Meeting.
Actively mode-locked semiconductor lasers need high quality antireflection coatings to avoid multiple pulse formation and mode-locking in clusters. The addition of an intrawaveguide saturable absorber eliminates these problems by absorbing the reflec

Monolithic 0.85-μm mode-locked semiconductor laser arrays
Autor: D. J. Derickson, P. A. Morton, G. Jia, R. S. Geels, J. E. Bowers, R. L. Thornton
Publikováno v: Integrated Photonics Research.
Mode-locked semiconductor lasers have produced ultra-short pulses in external cavity configurations by both active and passive methods. Recently, progress has been made1–3 in combining all of the required components into a single monolithic mode-lo

Manpower Needs for the Public Works Programs of the Julio-Claudian Emperors
Autor: R. L. Thornton, M. K. Thornton
Publikováno v: The Journal of Economic History. 43:373-378
The paper quantifies the relative manpower costs of the public building programs of the Julio-Claudian emperors of Rome from 29 b.c. to a.d. 68. We used both literary and archaeological sources for obtaining our data. Upon charting the data we discov
