Objective Although the number of female medical school graduates has dramatically increased over the last decades, Orthopaedic surgery continues to struggle in attracting …

Parallax error in long-axial field-of-view PET scanners-a simulation study.

Physics in medicine and biology

Schmall JP, Karp JS, Werner M, Surti S.
PMID: 27367971
Phys Med Biol. 2016 Jul 21;61(14):5443-5455. doi: 10.1088/0031-9155/61/14/5443. Epub 2016 Jul 01.

There is a growing interest in the design and construction of a PET scanner with a very long axial extent. One critical design challenge is the impact of the long axial extent on the scanner spatial resolution properties. In...

Design and Synthesis of Novel Macrocyclic Mer Tyrosine Kinase Inhibitors.

ACS medicinal chemistry letters

Wang X, Liu J, Zhang W, Stashko MA, Nichols J, Miley MJ, Norris-Drouin J, Chen Z, Machius M, DeRyckere D, Wood E, Graham DK, Earp HS, Kireev D, Frye SV.
PMID: 27994735
ACS Med Chem Lett. 2016 Sep 13;7(12):1044-1049. doi: 10.1021/acsmedchemlett.6b00221. eCollection 2016 Dec 08.

Mer tyrosine kinase (MerTK) is aberrantly elevated in various tumor cells and has a normal anti-inflammatory role in the innate immune system. Inhibition of MerTK may provide dual effects against these MerTK-expressing tumors through reducing cancer cell survival and...

Replication, falsification, and the crisis of confidence in social psychology.

Frontiers in psychology

Earp BD, Trafimow D.
PMID: 26042061
Front Psychol. 2015 May 19;6:621. doi: 10.3389/fpsyg.2015.00621. eCollection 2015.

The (latest) crisis in confidence in social psychology has generated much heated discussion about the importance of replication, including how it should be carried out as well as interpreted by scholars in the field. For example, what does it...

DTA-EGA determination of carbides chemically extracted from steel.

Talanta

Karp HS, Bandi WR, Melnick LM.
PMID: 18960056
Talanta. 1966 Dec;13(12):1679-87. doi: 10.1016/0039-9140(66)80252-7.

Differential thermal analysis-effluent gas analysis (DTA-EGA) techniques have been applied to the determination of specific metal carbides in residues which are isolated from steels by chemical methods. In this method, a weighed portion of sample residue is transferred to...

Estimating photosynthetic electron transport via chlorophyll fluorometry without Photosystem II light saturation.

Photosynthesis research

Earl HJ, Ennahli S.
PMID: 16151873
Photosynth Res. 2004;82(2):177-86. doi: 10.1007/s11120-004-1454-3.

Estimates of thylakoid electron transport rates (J(e)) from chlorophyll fluorometry are often used in combination with leaf gas exchange measurements to provide detailed information about photosynthetic activity of leaves in situ. Estimating J(e) requires accurate determination of the quantum...

The countrate performance of the volume imaging PENN-PET scanner.

IEEE transactions on medical imaging

Smith RJ, Karp JS, Muehllehner G.
PMID: 18218539
IEEE Trans Med Imaging. 1994;13(4):610-8. doi: 10.1109/42.363107.

The UGM PENN-PET camera uses large position sensitive detectors and operates without septa. This design results in high sensitivity and 3-D imaging capability, but poses problems in high countrate situations. The maximum true countrates and random countrates have been...

A method for reconstructing images from data obtained with a hexagonal bar positron camera.

IEEE transactions on medical imaging

Muehllehner G, Karp JS, Guvenis A.
PMID: 18243963
IEEE Trans Med Imaging. 1985;4(3):134-8. doi: 10.1109/TMI.1985.4307711.

This paper describes the algorithms and procedures developed for reconstructing images using the hexagonal bar positron camera. This camera has six continuous position-sensitive detectors which are completely stationary, and it has some special software requirements. In particular, spatial nonlinearities...

Effect of increased axial field of view on the performance of a volume PET scanner.

IEEE transactions on medical imaging

Karp JS, Kinahan PE, Muehllehner G, Countryman P.
PMID: 18218418
IEEE Trans Med Imaging. 1993;12(2):299-306. doi: 10.1109/42.232259.

The performance of the PENN-PET 240H scanner from UGM Medical Systems is tested and compared to the prototype PENN-PET scanner built at the University of Pennsylvania. The UGM PENN-PET scanner consists of six continuous position-sensitive NaI(Tl) detectors, which results...

Metal-in-metal localized surface plasmon resonance.

Nanotechnology

Smith GB, Earp AA.
PMID: 19946159
Nanotechnology. 2010 Jan 08;21(1):015203. doi: 10.1088/0957-4484/21/1/015203. Epub 2009 Nov 30.

Anomalous strong resonances in silver and gold nanoporous thin films which conduct are found to arise from isolated metal nano-islands separated from the surrounding percolating metal network by a thin loop of insulator. This observed resonant optical response is...

Imaging studies for evaluating impact of position sampling techniques in PET scanners.

IEEE transactions on nuclear science

Surti S, Werner ME, Karp JS.
PMID: 21547006
IEEE Trans Nucl Sci. 2010 Oct 01;57(5):2497-2503. doi: 10.1109/TNS.2010.2049121.

Previously we have evaluated two crystal calibration techniques that can be applied to pixelated detector designs to improve system spatial resolution without detector motion. The inter-crystal positioning technique utilizes sub-sampling in the crystal flood map to better sample the...
