Simultaneous consideration of tissue and substrate potassium concentration in k uptake kinetics: a model.

Plant physiology

Siddiqi MY, Glass AD.
PMID: 16662178
Plant Physiol. 1982 Jan;69(1):283-5. doi: 10.1104/pp.69.1.283.

The importance of the simultaneous consideration of tissue and substrate concentration in the estimation of ion uptake is discussed. An elaboration of the model of ion uptake, originally proposed by E. Epstein, is developed. The modified model takes both...

Metabolite fingerprinting in transgenic Nicotiana tabacum altered by the Escherichia coli glutamate dehydrogenase gene.

Journal of biomedicine & biotechnology

Mungur R, Glass AD, Goodenow DB, Lightfoot DA.
PMID: 16046826
J Biomed Biotechnol. 2005 Jun 30;2005(2):198-214. doi: 10.1155/JBB.2005.198.

With about 200,000 phytochemicals in existence, identifying those of biomedical significance is a mammoth task. In the postgenomic era, relating metabolite fingerprints, abundances, and profiles to genotype is also a large task. Ion analysis using Fourier transformed ion cyclotron...

Materials for optical information processing.

Science (New York, N.Y.)

Glass AM.
PMID: 17774930
Science. 1984 Nov 09;226(4675):657-62. doi: 10.1126/science.226.4675.657.

The goal for optical information processing is to use the unique characteristics of light which are not readily achieved with electronic devices, namely, ultrahigh speed (picoseconds), a high degree of parallelism (image processing), and conductor-free interconnection. The requirements of...

Correlations between Potassium Uptake and Hydrogen Efflux in Barley Varieties : A POTENTIAL SCREENING METHOD FOR THE ISOLATION OF NUTRIENT EFFICIENT LINES.

Plant physiology

Glass AD, Siddiqi MY, Giles KI.
PMID: 16661936
Plant Physiol. 1981 Aug;68(2):457-9. doi: 10.1104/pp.68.2.457.

Rates of hydrogen ion secretion and potassium ((86)Rb) absorption by intact roots of twenty-four barley varieties were measured in solutions containing K(2)SO(4) (1 x 10(-4) to 1 x 10(-3) molar) plus 5 x 10(-4) molar CaSO(4), at initial pH...

Laser induced damage in optical materials: 8th ASTM symposium.

Appl Opt. 1977 May 01;16(5):1214. doi: 10.1364/AO.16.001214.

The Eighth Annual Symposium on Optical Materials for High Power Lasers (Boulder Damage Symposium) was hosted by the National Bureau of Standards in Boulder, Colorado, from 13 to 15 July 1976. The Symposium was held under the auspices of...

The Effects of 24-hour Sleep Deprivation on the Exploration-Exploitation Trade-off.

Biological rhythm research

Glass BD, Maddox WT, Bowen C, Savarie ZR, Matthews MD, Markman AB, Schnyer DM.
PMID: 21686036
Biol Rhythm Res. 2011 Apr;42(2):99-110. doi: 10.1080/09291011003726532.

Sleep deprivation has a complex set of neurological effects that go beyond a mere slowing of mental processes. While cognitive and perceptual impairments in sleep deprived individuals are widespread, some abilities remain intact. In an effort to characterize these...

The Seventh ERDA-ASTM-ONR-NBS Symposium on Laser Induced Damage in Optical Materials was held at the National Bureau of Standards in Boulder, Colorado, on 29-31 July 1975. These Symposia are held as part of the activities in ASTM Subcommittee II...

Resonant photodiffractive four-wave mixing in semi-insulating GaAs/AlGaAs quantum wells.

Optics letters

Glass AM, Nolte DD, Olson DH, Doran GE, Chemla DS, Knox WH.
PMID: 19759777
Opt Lett. 1990 Mar 01;15(5):264-6. doi: 10.1364/ol.15.000264.

We have performed photodiffractive four-wave mixing in semi-insulating multiple GaAs/AlGaAs quantum wells at a wavelength of 0.83 microm. The quantum wells were made semi-insulating by proton implantation, which introduces defects that are available to trap and store charge during...

Optical metal-oxide tunnel detectors with microstructured electrodes.

Optics letters

Glass AM, Liao PF, Olson DH, Humphrey LM.
PMID: 19714096
Opt Lett. 1982 Dec 01;7(12):575-6. doi: 10.1364/ol.7.000575.

Order-of-magnitude improvement of the quantum efficiency of metal-oxide-metal detectors is achieved in the visible spectrum by fabricating the devices on silica substrates structured with a periodic array of bumps separated by about 0.25 microm. Structuring metallic films affords improved...
