Determining the optimal spectral sampling frequency and uncertainty thresholds for hyperspectral remote sensing of ocean color.

Optics express

Vandermeulen RA, Mannino A, Neeley A, Werdell J, Arnone R.
PMID: 29041046
Opt Express. 2017 Aug 07;25(16):A785-A797. doi: 10.1364/OE.25.00A785.

Using a modified geostatistical technique, empirical variograms were constructed from the first derivative of several diverse Remote Sensing Reflectance and Phytoplankton Absorbance spectra to describe how data points are correlated with "distance" across the spectra. The maximum rate of...

β-Mannoside mannohydrolase and the mobilization of the endosperm cell wall of lettuce seeds, cv. Grand Rapids.

Planta

Ouellette BF, Bewley JD.
PMID: 24232644
Planta. 1986 Nov;169(3):333-8. doi: 10.1007/BF00392128.

Mobilization of the endosperm cell-wall reserves of Lactuca sativa L. cv. Grand Rapids requires endo-β-mannanase and α-galactosidase activity. A third enzyme, β-mannoside mannohydrolase (EC 3.2.1.25) is also involved. We have determined the optimum extraction and assay conditions for this...

Erythema of Rosacea Impairs Health-Related Quality of Life: Results of a Meta-analysis.

Dermatology and therapy

Bewley A, Fowler J, Schöfer H, Kerrouche N, Rives V.
PMID: 26983751
Dermatol Ther (Heidelb). 2016 Jun;6(2):237-47. doi: 10.1007/s13555-016-0106-9. Epub 2016 Mar 16.

INTRODUCTION: The central diagnostic feature of rosacea is diffuse central-facial erythema. The objective was to summarize published and unpublished health-related quality of life (HRQoL) data from seven previous studies in rosacea patients.METHODS: A meta-analysis was performed on baseline HRQoL...

Contrasting pattern of somatic and zygotic embryo development in alfalfa (Medicago sativa L.) as revealed by scanning electron microscopy.

Plant cell reports

Xu N, Bewley JD.
PMID: 24203140
Plant Cell Rep. 1992 Jun;11(5):279-84. doi: 10.1007/BF00235082.

Scanning electron microscopy has been used to investigate the morphological changes occurring during the development of alfalfa somatic embryos. Embryos were initiated from callus, transferred to suspension culture and matured on solid agar medium. This developmental pattern was compared...

Plant desiccation and protein synthesis: an in vitro system from dry and hydrated mosses using endogenous and synthetic messenger ribonucleic Acid.

Plant physiology

Gwóźdź EA, Bewley JD.
PMID: 16659079
Plant Physiol. 1975 Feb;55(2):340-5. doi: 10.1104/pp.55.2.340.

The conditions and requirements for an in vitro protein synthesizing system from the moss Tortula ruralis are outlined. Using this system the effects of desiccation, achieved quickly or slowly, were studied. Slowly dried moss retained fewer polyribosomes on desiccation...

Desiccation of Axes of Phaseolus vulgaris during Development of a Switch from a Development Pattern of Protein Synthesis to a Germination Pattern.

Plant physiology

Dasgupta J, Bewley JD.
PMID: 16662643
Plant Physiol. 1982 Oct;70(4):1224-7. doi: 10.1104/pp.70.4.1224.

Immature seeds of Phaseolus vulgaris removed from the pod at 32 days of development do not germinate unless first subjected to a desiccation treatment. This change from development to germination caused by premature drying is mirrored in the pattern...

Lipid peroxidation associated with accelerated aging of soybean axes.

Plant physiology

Stewart RR, Bewley JD.
PMID: 16661168
Plant Physiol. 1980 Feb;65(2):245-8. doi: 10.1104/pp.65.2.245.

Soybean seeds age rapidly during storage at high temperature and high relative humidity. The axes of such aged seeds contain high levels of malondialdehyde, a product of the peroxidation of unsaturated fatty acids. The levels of linoleic (18:2) and...

Supramolecular isomers of metal-organic frameworks: the role of a new mixed donor imidazolate-carboxylate tetradentate ligand.

Dalton transactions (Cambridge, England : 2003)

Richards VJ, Argent SP, Kewley A, Blake AJ, Lewis W, Champness NR.
PMID: 22301665
Dalton Trans. 2012 Apr 14;41(14):4020-6. doi: 10.1039/c2dt12055k. Epub 2012 Feb 03.

Five new metal-organic frameworks prepared from the ligand 5-bis(3-(1-imidazolyl)propylcarbamoyl)terephthalate (bipta(2-)) and transition metal salts, Zn(2+) (1), Co(2+) (2), Mn(2+) (3, 4) and Cu(2+) (5), are reported. Single crystal X-ray studies reveal that the bipta(2-) ligand acts as a tetradentate...

Drying without senescence in resurrection plants.

Frontiers in plant science

Griffiths CA, Gaff DF, Neale AD.
PMID: 24575108
Front Plant Sci. 2014 Feb 12;5:36. doi: 10.3389/fpls.2014.00036. eCollection 2014.

Research into extreme drought tolerance in resurrection plants using species such as Craterostigma plantagineum, C. wilmsii, Xerophyta humilis, Tortula ruralis, and Sporobolus stapfianus has provided some insight into the desiccation tolerance mechanisms utilized by these plants to allow them...

A distinction between the actions of abscisic acid, gibberellic acid and cytokinins in light-sensitive lettuce seed.

Planta

Bewley JD, Fountain DW.
PMID: 24482278
Planta. 1972 Dec;102(4):368-71. doi: 10.1007/BF00386622.

Using isolated lettuce seed embryos it can be shown that the inhibitory effect of abscisic acid upon germination is reversed solely by cytokinin. In the intact seed, however, gibberellic acid is also required for this reversal to be manifested...
