Building black holes: supercomputer cinema.

Science (New York, N.Y.)

Shapiro SL, Teukolsky SA.
PMID: 17792605
Science. 1988 Jul 22;241(4864):421-5. doi: 10.1126/science.241.4864.421.

A new computer code can solve Einstein's equations of general relativity for the dynamical evolution of a relativistic star cluster. The cluster may contain a large number of stars that move in a strong gravitational field at speeds approaching...

Crossover cutting during hamstring fatigue produces transverse plane knee control deficits.

Journal of athletic training

Nyland JA, Caborn DN, Shapiro R, Johnson DL.
PMID: 16558556
J Athl Train. 1999 Apr;34(2):137-43.

OBJECTIVE: To assess the effects of eccentric work-induced hamstring fatigue on sagittal and transverse plane (axial) knee and ankle biodynamics and kinetics during a running crossover cut directional change (functional pivot shift).DESIGN AND SETTING: A pretest-posttest, single-group intervention experimental...

Development and cross-validation of a short form impairment index.

Archives of clinical neuropsychology : the official journal of the National Academy of Neuropsychologists

Horton AM, Anilane J, Slone DG, Shapiro S.
PMID: 14591152
Arch Clin Neuropsychol. 1986;1(3):243-6.

The Brain Age Quotient (BAQ) is an actuarial combination of four Halstead-Reitan neuropsychology test battery scores (Category errors. Tactual Performance Test- Total Time, Tactual Performance Test-Location Score and Trails-B Score) and two performance subtests for the Wechsler Adult Intelligence...

Functional multijoint position reproduction acuity in overhead-throwing athletes.

Journal of athletic training

Tripp BL, Uhl TL, Mattacola CG, Srinivasan C, Shapiro R.
PMID: 16791298
J Athl Train. 2006 Apr-Jun;41(2):146-53.

CONTEXT: Baseball players rely on the sensorimotor system to uphold the balance between upper extremity stability and mobility while maintaining athletic performance. However, few researchers have studied functional multijoint measures of sensorimotor acuity in overhead-throwing athletes.OBJECTIVE: To compare sensorimotor...

Correlation of hydronephrosis index to society of fetal urology hydronephrosis scale.

Advances in urology

Venkatesan K, Green J, Shapiro SR, Steinhardt GF.
PMID: 19255628
Adv Urol. 2009;960490. doi: 10.1155/2009/960490. Epub 2009 Feb 25.

Purpose. We seek to correlate conventional hydronephrosis (HN) grade and hydronephrosis index (HI). Methods. We examined 1207 hydronephrotic kidneys by ultrasound. HN was classified by Society of Fetal Urology guidelines. HN was then gauged using HI, a reproducible, standardized,...

Broadly tunable picosecond infrared source.

Optics letters

Campillo AJ, Hyer RC, Shapiro SL.
PMID: 19687892
Opt Lett. 1979 Oct 01;4(10):325-7. doi: 10.1364/ol.4.000325.

We report a completely grating tuned (1.9-2.4 microm) picosecond traveling-wave infrared generator capable of controlled spectral-bandwidth operation down to the Fourier-transform limit. Subsequent down-conversion in CdSe extends the tuning range to 10-20 microm.

POSTOPERATIVE THROMBO-EMBOLIZATION: THE PLATELET COUNT AND THE PROTHROMBIN TIME AFTER SURGICAL OPERATIONS: A SIMPLE METHOD FOR DETECTING REDUCTIONS AND ELEVATIONS OF THE PROTHROMBIN CONCENTRATION (OR ACTIVITY) OF THE BLOOD PLASMA.

Handedness for tool use in captive chimpanzees (Pan troglodytes): Sex differences, performance, heritability and comparison to the wild.

Behaviour

Hopkins WD, Russell JL, Schaeffer JA, Gardner M, Schapiro SJ.
PMID: 20221316
Behaviour. 2009 Jan 01;146(11):1463-1483. doi: 10.1163/156853909X441005.

There is continued debate over the factors influencing handedness in captive and wild primates, notably chimpanzees. Previous studies in wild chimpanzees have revealed population-level left handedness for termite fishing. Here we examined hand preferences and performance on a tool...

Collapse of magnetized hypermassive neutron stars in general relativity.

Physical review letters

Duez MD, Liu YT, Shapiro SL, Shibata M, Stephens BC.
PMID: 16486677
Phys Rev Lett. 2006 Jan 27;96(3):031101. doi: 10.1103/PhysRevLett.96.031101. Epub 2006 Jan 25.

Hypermassive neutron stars (HMNSs)--equilibrium configurations supported against collapse by rapid differential rotation--are possible transient remnants of binary neutron-star mergers. Using newly developed codes for magnetohydrodynamic simulations in dynamical spacetimes, we are able to track the evolution of a magnetized...

Geometric constructions for predicting hough transform performance.

IEEE transactions on pattern analysis and machine intelligence

Shapiro SD, Iannino A.
PMID: 21868864
IEEE Trans Pattern Anal Mach Intell. 1979 Mar;1(3):310-7. doi: 10.1109/tpami.1979.4766929.

Graphical techniques are presented for estimating Hough transform performance for detecting straight lines in noisy digital pictures. The methods show explicitly the influence of noise due, for example, to quantizing errors on the accuracy of estimating the underlying sets...
