Avalanche photodiodes are commonly used as detectors for low energy x-rays. In this work, we report on a fitting technique used to account for different detector responses resulting from photoabsorption in the various avalanche photodiode layers. The use of...

Summers GF, Burke M, Saltiel S, Clark JP.
PMID: 26744793
Multivariate Behav Res. 1971 Jan 01;6(1):35-62. doi: 10.1207/s15327906mbr0601_3.

The Work Component Study was administered to high school students and the stability of the structure of the variables of work motivation examined. The strudure found among college students and college trained employees is well developed at the high...

Estimating Population Size Using the Network Scale Up Method.

The annals of applied statistics

Maltiel R, Raftery AE, McCormick TH, Baraff AJ.
PMID: 26949438
Ann Appl Stat. 2015 Sep;9(3):1247-1277. doi: 10.1214/15-AOAS827.

We develop methods for estimating the size of hard-to-reach populations from data collected using network-based questions on standard surveys. Such data arise by asking respondents how many people they know in a specific group (e.g. people named Michael, intravenous...

Photoisomerization of cis-1,2-di(1-Methyl-2-naphthyl)ethene at 77 K in Glassy Media.

Photochemistry and photobiology

Photochem Photobiol. 2015 May-Jun;91(3):607-15. doi: 10.1111/php.12367. Epub 2014 Nov 21.

cis-1,2-Di(1-methyl-2-naphthyl)ethene, c-1,1, undergoes photoisomerization in methylcyclohexane, isopentane and diethyl ether/isopentane/ethanol glasses at 77 K. On 313 nm excitation the fluorescence of c-1,1 is replaced by fluorescence from t-1,1. Singular value decomposition reveals that the spectral matrices behave as two...

Resonant quenching of gas-phase Cs atoms induced by surface polaritons.

Physical review letters

Failache H, Saltiel S, Fischer A, Bloch D, Ducloy M.
PMID: 12059297
Phys Rev Lett. 2002 Jun 17;88(24):243603. doi: 10.1103/PhysRevLett.88.243603. Epub 2002 May 31.

Near-field coupling between an excited atom and a surface-polariton mode can dramatically modify atomic branching ratios, because of surface-induced enhancement of a resonant decay channel. We show here that Cs(6D(3/2)) transfer towards Cs(7P(1/2)) (at lambda = 12.15 microm), negligible...

all-trans-1,4-Diindanylidenyl-2-butene (ttt-stiff-5-DPH), a torsionally constrained analogue of all-trans-1,6-diphenyl-1,3,5-hexatriene (ttt-DPH), was synthesized and studied in order to evaluate the role of phenyl-vinyl torsional motions in the photophysical and photochemical responses of the DPH chromophore. Spectroscopic and photoisomerization measurements reveal that...

Aggregation behavior of single-walled carbon nanotubes in dilute aqueous suspension.

Journal of colloid and interface science

Chen Q, Saltiel C, Manickavasagam S, Schadler LS, Siegel RW, Yang H.
PMID: 15476778
J Colloid Interface Sci. 2004 Dec 01;280(1):91-7. doi: 10.1016/j.jcis.2004.07.028.

The aggregation behavior of colloidal single-walled carbon nanotubes (SWNT) in dilute aqueous suspensions was investigated using a novel light scattering measurement technique. The aggregation of SWNT in three suspensions was examined: (1) nanotubes after acid treatment; (2) as-received nanotubes...

Nonlinear mirror based on cross-polarized wave generation.

Optics letters

Opt Lett. 2006 Nov 01;31(21):3143-5. doi: 10.1364/ol.31.003143.

We present a new type of nonlinear mirror based on the generation of a cross-polarized wave through a nonresonant electronic third-order process. It is characterized by a reflection coefficient that depends on the input intensity. Its behavior results from...

We investigate the influence of a uniform magnetic field B(0)=B(0)e( parallel) on energy decay laws in incompressible magnetohydrodynamic (MHD) turbulence. The nonlinear transfer reduction along B(0) is included in a model that distinguishes parallel and perpendicular directions, following a...
