Relationship between Selected Physical Characteristics and Functional Capacity in the Anterior Cruciate Ligament-Insufficient Athlete.

The Journal of orthopaedic and sports physical therapy

Lephart SM, Perrin DH, Fu FH, Gieck JH, McCue FC, Irrgang JJ.
PMID: 18796757
J Orthop Sports Phys Ther. 1992;16(4):174-81. doi: 10.2519/jospt.1992.16.4.174.

Traditionally, clinicians have utilized various physical characteristics as criteria to assess the functional status of anterior cruciate ligament (ACL)-insufficient athletes without validating the efficacy of such assessments. The primary purposes of this study were to determine the relationship between...

J Orthop Sports Phys Ther. 1991;14(3):114-20. doi: 10.2519/jospt.1991.14.3.114.

This study was supported in part by a grant from the Foundation for Physical Therapy, Inc. The purpose of this study was to compare the relationships among isometric, isotonic, and isokinetic concentric and eccentric quadriceps and hamstring forces and...

Comparison of isokinetic strength and flexibility measures between hamstring injured and noninjured athletes.

Worrell TW, Perrin DH, Gansneder BM, Gieck JH.
PMID: 18796850
J Orthop Sports Phys Ther. 1991;13(3):118-25. doi: 10.2519/jospt.1991.13.3.118.

The purpose of this study was to compare isokinetic strength and flexibility measures between hamstring injured and noninjured athletes. Sixteen university athletes with history of hamstring injury were matched by motor dominance, sport, and position to sixteen university athletes...

Optical Stark effect in a quantum dot: ultrafast control of single exciton polarizations.

Physical review letters

Unold T, Mueller K, Lienau C, Elsaesser T, Wieck AD.
PMID: 15169317
Phys Rev Lett. 2004 Apr 16;92(15):157401. doi: 10.1103/PhysRevLett.92.157401. Epub 2004 Apr 16.

We report the first experimental study of the optical Stark effect in single semiconductor quantum dots (QD). For below band gap excitation, two-color pump-probe spectra show dispersive line shapes caused by a light-induced blueshift of the excitonic resonance. The...

Motivational congruency and discrepancy of hawaiian athletic trainers.

Journal of athletic training

Buxton BP, Lankford SV, Gieck JH.
PMID: 16558188
J Athl Train. 1992;27(4):326-33.

Motivation is an integral part of an effective organizational management scheme. In March 1992, we sent a survey designed to assess motivational preference to all certified athletic trainers in the State of Hawaii. The population included: 6 high school...

Mechanisms and management of stress fractures in physically active persons.

Journal of athletic training

Romani WA, Gieck JH, Perrin DH, Saliba EN, Kahler DM.
PMID: 16558676
J Athl Train. 2002 Jul;37(3):306-14.

OBJECTIVE: To describe the anatomy of bone and the physiology of bone remodeling as a basis for the proper management of stress fractures in physically active people.DATA SOURCES: We searched PubMed for the years 1965 through 2000 using the...

Spin accumulation and spin relaxation in a large open quantum dot.

Physical review letters

Koop EJ, van Wees BJ, Reuter D, Wieck AD, van der Wal CH.
PMID: 18764414
Phys Rev Lett. 2008 Aug 01;101(5):056602. doi: 10.1103/PhysRevLett.101.056602. Epub 2008 Jul 29.

We report electronic control and measurement of an imbalance between spin-up and spin-down electrons in micron-scale open quantum dots. Spin injection and detection were achieved with quantum point contacts tuned to have spin-selective transport, with four contacts per dot...

Temperature-dependent quantitative 3omega scanning thermal microscopy: Local thermal conductivity changes in NiTi microstructures induced by martensite-austenite phase transition.

The Review of scientific instruments

Chirtoc M, Gibkes J, Wernhardt R, Pelzl J, Wieck A.
PMID: 19044421
Rev Sci Instrum. 2008 Sep;79(9):093703. doi: 10.1063/1.2982235.

We develop the theoretical description of 3omega signals from the resistive Wollaston thermal probe (ThP) of a scanning thermal microscope (SThM) in terms of an equivalent low-pass filter. The normalized amplitude and phase frequency spectra are completely characterized by...

Nuclei-induced frequency focusing of electron spin coherence.

Science (New York, N.Y.)

Greilich A, Shabaev A, Yakovlev DR, Efros AL, Yugova IA, Reuter D, Wieck AD, Bayer M.
PMID: 17901328
Science. 2007 Sep 28;317(5846):1896-9. doi: 10.1126/science.1146850.

The hyperfine interaction of an electron with the nuclei is considered as the primary obstacle to coherent control of the electron spin in semiconductor quantum dots. We show, however, that the nuclei in singly charged quantum dots act constructively...

Optical water quality model of Lake Ontario. 2: Determination of chlorophyll a and suspended mineral concentrations of natural waters from submersible and low altitude optical sensors.
