Exclusive annihilation pp-->gammagamma in a generalized Parton picture.

Physical review letters

Freund A, Radyushkin AV, Schäfer A, Weiss C.
PMID: 12689214
Phys Rev Lett. 2003 Mar 07;90(9):092001. doi: 10.1103/PhysRevLett.90.092001. Epub 2003 Mar 03.

Exclusive proton-antiproton annihilation into two photons at large s ( approximately 10 GeV2) and /t/,/u/ approximately s can be described by a generalized parton picture analogous to the "soft mechanism" in wide-angle real Compton scattering. The two photons are...

Surveillance for respiratory illness in long-term care settings: detection of illness using a prospective research technique.

Journal of the American Medical Directors Association

Gravenstein S, Ambrozaitis A, Schilling M, Radzisauskiene D, Krause P, Drinka P, Shult P, Freund B.
PMID: 12818025
J Am Med Dir Assoc. 2000 May-Jun;1(3):122-8.

BACKGROUND: The overall frequency and severity of viral respiratory infections affecting residents of long-term care facilities (LTCFs) is not well described. This is due primarily to the cumbersome and expensive techniques required for adequate surveillance of respiratory illnesses and...

Bridging the pressure and materials gaps: high pressure sum frequency generation study on supported Pd nanoparticles.

Physical review letters

Selection, optimization, and compensation as strategies of life management: correction to Freund and Baltes (1998).

Psychol Aging. 1999 Dec;14(4):700-2. doi: 10.1037/0882-7974.14.4.700.

Because of a scoring error, the data reported in Freund and Baltes (1998) were reanalyzed. Except for finding a lower positive manifold involving the 3 components of selection, optimization, and compensation (SOC), the outcome of this reanalysis supports the...

CH stretching bands, nu(CH), in the infrared spectrum of single crystals of nominally high purity, of laboratory-grown MgO, and of natural upper mantle olivine, provide an "organic" signature that closely resembles the symmetrical and asymmetrical C--H stretching modes of...

The canonical point singularity of elliptically polarized light is a C point, an isolated point of circular polarization surrounded by a field of polarization ellipses. The defining singular property of a C point is that the surrounding ellipses rotate...

Freund M, Bodalbhai L, Brajter-Toth A.
PMID: 18965110
Talanta. 1991 Jan;38(1):95-9. doi: 10.1016/0039-9140(91)80014-q.

A new method for modifying polypyrrole films is described. It involves complete oxidation of the film. The film produced is electronically non-conductive but ionically conductive, and has ion-selective properties based on the exclusion of anionic species. The effective pH...
