On the division of profit in sequential innovation

teaching innovation

Green JR.

JR Green, S Scotchmer - The Rand journal of economics, 1995 - JSTOR

In markets with sequential innovation, inventors of derivative improvements might undermine the profit of initial innovators through competition. Profit erosion can be mitigated …

Ultrahigh strength of dislocation-free Ni3Al nanocubes.

Small (Weinheim an der Bergstrasse, Germany)

Maaß R, Meza L, Gan B, Tin S, Greer JR.
PMID: 22454244
Small. 2012 Jun 25;8(12):1869-75. doi: 10.1002/smll.201102603. Epub 2012 Mar 27.

Individual Ni(3) Al nanocubes under pressure are investigated by comparing the compressive strength of both dislocation-free and irradiated Ni(3) Al nanocubes. The results are dicussed in light of the size-dependent and size-independent strength of face-centered cubic (fcc) nanocrystals in...

Probing Microplasticity in Small-Scale FCC Crystals via Dynamic Mechanical Analysis.

Physical review letters

Ni X, Papanikolaou S, Vajente G, Adhikari RX, Greer JR.
PMID: 28452540
Phys Rev Lett. 2017 Apr 14;118(15):155501. doi: 10.1103/PhysRevLett.118.155501. Epub 2017 Apr 14.

In small-scale metallic systems, collective dislocation activity has been correlated with size effects in strength and with a steplike plastic response under uniaxial compression and tension. Yielding and plastic flow in these samples is often accompanied by the emergence...

Self-Averaging Fluctuations in the Chaoticity of Simple Fluids.

Physical review letters

Das M, Green JR.
PMID: 28949206
Phys Rev Lett. 2017 Sep 15;119(11):115502. doi: 10.1103/PhysRevLett.119.115502. Epub 2017 Sep 14.

Bulk properties of equilibrium liquids are a manifestation of intermolecular forces. Here, we show how these forces imprint on dynamical fluctuations in the Lyapunov exponents for simple fluids with and without attractive forces. While the bulk of the spectrum...

Reproductive Genetic Counseling to Asian-Pacific and Latin American Immigrants.

Journal of genetic counseling

Mittman I, Crombleholme WR, Green JR, Golbus MS.
PMID: 26141096
J Genet Couns. 1998 Feb;7(1):49-70. doi: 10.1023/A:1022816128420.

Latin and Asian-Pacific immigrants are the fastest growing new-comer groups in the U.S. contributing to 85% of immigration totals. New immigrants experience multiple barriers to accessing genetic counseling resulting from cultural, linguistic, financial, and educational factors as well as...

Enabling Simultaneous Extreme Ultra Low-k in Stiff, Resilient, and Thermally Stable Nano-Architected Materials.

Nano letters

Lifson ML, Kim MW, Greer JR, Kim BJ.
PMID: 29112423
Nano Lett. 2017 Dec 13;17(12):7737-7743. doi: 10.1021/acs.nanolett.7b03941. Epub 2017 Nov 09.

Low dielectric constant (low-k) materials have gained increasing popularity because of their critical role in developing faster, smaller, and higher performance devices. Their practical use has been limited by the strong coupling among mechanical, thermal, and electrical properties of...

The nature of magnetoelectric coupling in Pb(Zr,Ti)O3 -Pb(Fe,Ta)O3.

Advanced materials (Deerfield Beach, Fla.)

Evans DM, Alexe M, Schilling A, Kumar A, Sanchez D, Ortega N, Katiyar RS, Scott JF, Gregg JM.
PMID: 26351267
Adv Mater. 2015 Oct 21;27(39):6068-73. doi: 10.1002/adma.201501749. Epub 2015 Sep 09.

The coupling between magnetization and polarization in a room temperature multiferroic (Pb(Zr,Ti)O3 -Pb(Fe,Ta)O3 ) is explored by monitoring the changes in capacitance that occur when a magnetic field is applied in each of three orthogonal directions. Magnetocapacitance effects, consistent...

The challenge to improve the response of biomaterials to the physiological environment.

Regenerative biomaterials

Peppas NA, Clegg JR.
PMID: 27047671
Regen Biomater. 2016 Jun;3(2):67-71. doi: 10.1093/rb/rbw012. Epub 2016 Mar 10.

New applications of biomaterials often require advanced structures containing synthetic and natural components that are tuned to provide properties unique to a specific application. We discuss how structural characteristics of biomaterials, especially hydrophilic ones, can be used in conjunction...

Fractal atomic-level percolation in metallic glasses.

Science (New York, N.Y.)

Chen DZ, Shi CY, An Q, Zeng Q, Mao WL, Goddard WA, Greer JR.
PMID: 26383945
Science. 2015 Sep 18;349(6254):1306-10. doi: 10.1126/science.aab1233.

Metallic glasses are metallic alloys that exhibit exotic material properties. They may have fractal structures at the atomic level, but a physical mechanism for their organization without ordering has not been identified. We demonstrated a crossover between fractal short-range...

Chronic eosinophilic leukemia, NOS with t(5;12)(q31;p13)/ETV6-ACSL6 gene fusion: a novel variant of myeloid proliferative neoplasm with eosinophilia.

Human pathology (New York)

Su RJ, Jonas BA, Welborn J, Gregg JP, Chen M.
PMID: 27458550
Hum Pathol (N Y). 2016 Sep;5:6-9. doi: 10.1016/j.ehpc.2015.10.001.

The 2008 World Health Organization (WHO) classification of tumors of hematopoietic and lymphoid tissues introduced a category for myeloid and lymphoid neoplasms with eosinophilia and abnormalities of PDGFRA, PDGFRB or FGFR1. Many of these patients are responsive to tyrosine...
