Evaluation of a web-based weight loss intervention in overweight cancer survivors aged 50 years and younger.

Obesity science & practice

Lynch SM, Stricker CT, Brown JC, Berardi JM, Vaughn D, Domchek S, Filseth S, Branas A, Weiss-Trainor E, Schmitz KH, Sarwer DB.
PMID: 28392934
Obes Sci Pract. 2017 Mar;3(1):83-94. doi: 10.1002/osp4.98. Epub 2017 Feb 24.

PURPOSE: Half of adult cancer survivors under age 50 years are obese. Excess body weight is associated with cancer recurrence, and effective weight loss interventions for younger cancer survivors are needed. Commercially available, online weight loss programmes are readily...

Eliminating thermal effects in z-scan measurements of thin PTCDA films.

Optics express

Wickremasinghe N, Wang X, Schmitzer H, Wagner HP.
PMID: 25321972
Opt Express. 2014 Oct 06;22(20):23955-64. doi: 10.1364/OE.22.023955.

We investigate the two-photon absorption (TPA) and nonlinear refraction of a micrometer thick 3,4,9,10-perylentetracarboxyl-dianhydride (PTCDA) film using z-scans with tightly focused 100 fs laser pulses. The PTCDA film was grown by organic molecular beam deposition on a Pyrex substrate....

Beam mixing with a pinhole.

Journal of the Optical Society of America. A, Optics, image science, and vision

Schmid K, Frins E, Schmitzer H, Dultz W.
PMID: 16396027
J Opt Soc Am A Opt Image Sci Vis. 2005 Dec;22(12):2672-6. doi: 10.1364/josaa.22.002672.

After a small aperture the spatial information of a complex optical wavefront is lost, but amplitude and phase information is mixed and transferred to the smoothed wave that emerges from the pinhole. This mixing effect is described in the...

Effect of Au substrate and coating on the lasing characteristics of GaAs nanowires.

Scientific reports

Aman G, Mohammadi F, Fränzl M, Lysevych M, Tan HH, Jagadish C, Schmitzer H, Cahay M, Wagner HP, Fredrick LD.
PMID: 34725406
Sci Rep. 2021 Nov 01;11(1):21378. doi: 10.1038/s41598-021-00855-w.

Optically pumped lasing from highly Zn-doped GaAs nanowires lying on an Au film substrate and from Au-coated nanowires has been demonstrated up to room temperature. The conically shaped GaAs nanowires were first coated with a 5 nm thick Al

Comparison of the validity of anthropometric and bioelectric impedance equations to assess body composition in adolescent girls.

International journal of body composition research

Loftin M, Nichols J, Going S, Sothern M, Schmitz KH, Ring K, Tuuri G, Stevens J.
PMID: 18163160
Int J Body Compos Res. 2007;5(1):1-8.

OBJECTIVE: The purpose of this study was to examine the validity of two anthropometric and four bioelectric impedance (BIA) equations to estimate body composition from dual-energy x-ray absorptiometry (DXA) in adolescent girls of various ethnicities. The rationale for this...

Real-time contrast-enhanced holographic imaging using phase coherent photorefractive quantum wells.

Optics express

Dongol A, Thompson J, Schmitzer H, Tierney D, Wagner HP.
PMID: 26074534
Opt Express. 2015 May 18;23(10):12795-807. doi: 10.1364/OE.23.012795.

We demonstrate wide-field real-time and depth-resolved contrast enhanced holographic imaging (CEHI) using the all-optical phase coherent photorefractive effect in ZnSe quantum wells. Moving objects are imaged at large depth-of-field by the local enhancement of a static reference hologram. The...

Phase-matched third-harmonic generation in mercury-(I)-chloride.

Applied optics

Schmitzer H, Wagner HP, Dultz W, Kühnelt M.
PMID: 11905573
Appl Opt. 2002 Jan 20;41(3):470-4. doi: 10.1364/ao.41.000470.

Using phase-matched third-harmonic generation we determine the effective nonlinear susceptibilities in Hg2Cl2 (Calomel) to /chi(3)eff,I/ = 4.5 x 10(-22) m2V(-2) and /chi(3)eff,II/ = 9.7 x 10(-22) m2V(-2) for type I and type II phase matching, respectively. The type III...

Observation of the transfer of the local angular momentum density of a multiringed light beam to an optically trapped particle.

Physical review letters

Garcés-Chávez V, McGloin D, Padgett MJ, Dultz W, Schmitzer H, Dholakia K.

Phys Rev Lett. 2003 Aug 29;91(9):093602. doi: 10.1103/PhysRevLett.91.093602. Epub 2003 Aug 29.

We observe the spinning and orbital motion of a microscopic particle trapped within a multiringed light beam that arises from the transfer of the spin and orbital components of the light's angular momentum. The two rotation rates are measured...

Interferometric optical path measurement of a glass wedge with single photons and biphotons.

Optics letters

Schmid K, Becker H, Dultz W, Martienssen W, Kempe M, Schmitzer H.

Opt Lett. 2007 Aug 01;32(15):2257-9. doi: 10.1364/ol.32.002257.

We have measured the phase structure of a glass wedge with single photons and biphotons in a Mach-Zehnder interferometer using parametric downconverted light from a Hong-Ou-Mandel particle interferometer as the source. By scanning the wedge through the focus of...
