Generation of single-frequency coherent transition radiation by a prebunched electron beam traversing a vacuum beam tunnel in a periodic medium.

Physical review. E, Statistical, nonlinear, and soft matter physics

Coleman PD, Lerttamrab M, Gao J.
PMID: 12513422
Phys Rev E Stat Nonlin Soft Matter Phys. 2002 Dec;66(6):066502. doi: 10.1103/PhysRevE.66.066502. Epub 2002 Dec 31.

A classical Maxwell equation longitudinal boundary value problem analysis of a prebunched ac electron beam traversing a vacuum tunnel in a periodic layered dielectric medium is used to calculate the single-frequency coherent transition radiation power generated per unit length....

Screening for preclinical type 1 diabetes in a discrete population with an apparent increased disease incidence.

Pediatric diabetes

Colman PG, McNair P, King J, Caudwell J, Jankulovski C, Tait BD, Honeyman MC, Harrison LC.
PMID: 15016215
Pediatr Diabetes. 2000 Dec;1(4):193-8. doi: 10.1034/j.1399-5448.2000.001004193.x.

Environmental agents are proposed to play a role in triggering or exacerbating pancreatic islet autoimmunity in people genetically predisposed to type 1 diabetes. However, with few exceptions, these agents remain enigmatic. Clues to environmental agents may be found by...

Magnetic Field.

Science (New York, N.Y.)

Smith EJ, Davis L, Coleman PJ, Sonett CP.
PMID: 17743053
Science. 1963 Mar 08;139(3558):909-10. doi: 10.1126/science.139.3558.909.

Mariner II magnetometer data gave no indication of a Venusian magnetic field. This implies, by comparison with spacecraft measurements near Earth and with theoretical models, that the magnetic dipole moment of Venus is at most 1/10 to 1/20 that...

Ectopic pituitary fossa thyroid tissue.

J Clin Neurosci. 1997 Jul;4(3):360-3. doi: 10.1016/s0967-5868(97)90108-9.

Developmental anomalies of the thyroid gland may result in ectopic glandular tissue. We report a unique case of ectopic thyroid tissue within the pituitary fossa and sphenoid sinus, associated with a lingual thyroid gland. The aetiology of this ectopic...

Lunar magnetic field: permanent and induced dipole moments.

Apollo 15 subsatellite magnetic field observations have been used to measure both the permanent and the induced lunar dipole moments. Although only an upper limit of 1.3 x 10(18) gauss-cubic centimeters has been determined for the permanent dipole moment...

Observation of parametric gain due to four-wave mixing in dispersion engineered GaInP photonic crystal waveguides.

Optics letters

Colman P, Cestier I, Willinger A, Combrié S, Lehoucq G, Eisenstein G, De Rossi A.
PMID: 21765490
Opt Lett. 2011 Jul 15;36(14):2629-31. doi: 10.1364/OL.36.002629.

We investigate four-wave mixing (FWM) in GaInP 1.5 mm long dispersion engineered photonic crystal waveguides. We demonstrate an 11 nm FWM bandwidth in the CW mode and a conversion efficiency of -24 dB in the quasi-CW mode. For picosecond...

Monovacancy and interstitial migration in ion-implanted silicon.

Physical review letters

Coleman PG, Burrows CP.
PMID: 17678103
Phys Rev Lett. 2007 Jun 29;98(26):265502. doi: 10.1103/PhysRevLett.98.265502. Epub 2007 Jun 29.

The migration of monovacancies (V0) and self-interstitials (I) has been observed in ion-implanted low-doped float-zone silicon by variable-energy positron annihilation spectroscopy. V0 and I were created by the in situ implantation of approximately 20 keV helium ions below 50...
