Structural dynamics and robustness of food webs.

Ecology letters

Staniczenko PP, Lewis OT, Jones NS, Reed-Tsochas F.
PMID: 20482578
Ecol Lett. 2010 Jul;13(7):891-9. doi: 10.1111/j.1461-0248.2010.01485.x. Epub 2010 May 12.

Food web structure plays an important role when determining robustness to cascading secondary extinctions. However, existing food web models do not take into account likely changes in trophic interactions ('rewiring') following species loss. We investigated structural dynamics in 12...

Selective detection of luminescence from semiconductor quantum dots by nanosecond time-gated imaging with a colour-masked CCD detector.

Journal of microscopy

Mitchell AC, Dad S, Morgan CG.
PMID: 18445145
J Microsc. 2008 May;230:172-6. doi: 10.1111/j.1365-2818.2008.01973.x.

Quantum dots are of considerable interest as highly detectable labels with broad absorption, narrow spectral emission and good quantum yields. The luminescence emission has a longer decay time than that of the most common fluorophores, leading to facile rejection...

1H and 13C solution- and solid-state NMR investigation into wax products from the Fischer-Tropsch process.

Solid state nuclear magnetic resonance

Speight RJ, Rourke JP, Wong A, Barrow NS, Ellis PR, Bishop PT, Smith ME.
PMID: 21536414
Solid State Nucl Magn Reson. 2011 May-Jun;39(3):58-64. doi: 10.1016/j.ssnmr.2011.03.008. Epub 2011 Apr 14.

(1)H and (13)C solid- and solution-state NMR have been used to characterise waxes produced in the Fischer-Tropsch reaction, using Co-based catalysts either unpromoted or promoted with approximately 1 wt% of either cerium or rhenium. The aim was to measure...

Diversity-oriented synthesis as a tool for the discovery of novel biologically active small molecules.

Nature communications

Galloway WR, Isidro-Llobet A, Spring DR.
PMID: 20865796
Nat Commun. 2010 Sep 21;1:80. doi: 10.1038/ncomms1081.

Biologically active molecules can be identified through the screening of small-molecule libraries. Deficiencies in current compound collections are evidenced by the continuing decline in drug-discovery successes. Typically, such collections are comprised of large numbers of structurally similar compounds. A...

Developing an online programme in computational biology.

Briefings in bioinformatics

Vincent HM, Page C.
PMID: 22988255
Brief Bioinform. 2013 Nov;14(6):775-83. doi: 10.1093/bib/bbs059. Epub 2012 Sep 17.

Much has been written about the need for continuing education and training to enable life scientists and computer scientists to manage and exploit the different types of biological data now becoming available. Here we describe the development of an...

Open source libraries and frameworks for mass spectrometry based proteomics: a developer's perspective.

Biochimica et biophysica acta

Perez-Riverol Y, Wang R, Hermjakob H, Müller M, Vesada V, Vizcaíno JA.
PMID: 23467006
Biochim Biophys Acta. 2014 Jan;1844(1):63-76. doi: 10.1016/j.bbapap.2013.02.032. Epub 2013 Mar 01.

Data processing, management and visualization are central and critical components of a state of the art high-throughput mass spectrometry (MS)-based proteomics experiment, and are often some of the most time-consuming steps, especially for labs without much bioinformatics support. The...

Swarm dynamics may give rise to Lévy flights.

Scientific reports

Reynolds AM, Ouellette NT.
PMID: 27465971
Sci Rep. 2016 Jul 28;6:30515. doi: 10.1038/srep30515.

"Continuous-time correlated random walks" are now gaining traction as models of scale-finite animal movement patterns because they overcome inherent shortcomings with the prevailing paradigm - discrete random walk models. Continuous-time correlated random walk models are founded on the classic...

Interactions in Water-Ionic Liquid Mixtures: Comparing Protic and Aprotic Systems.

The journal of physical chemistry. B

Reid JE, Gammons RJ, Slattery JM, Walker AJ, Shimizu S.
PMID: 28084738
J Phys Chem B. 2017 Jan 26;121(3):599-609. doi: 10.1021/acs.jpcb.6b10562. Epub 2017 Jan 13.

The sensitivity of ionic liquids (ILs) to water affects their physical and chemical properties, even at relatively low concentrations, yet the structural thermodynamics of protic IL- (PIL-) water systems at low water concentrations still remains unclear. Using the rigorous...

Synthesis and Reactivity of Propargylamines in Organic Chemistry.

Chemical reviews

Lauder K, Toscani A, Scalacci N, Castagnolo D.
PMID: 29166000
Chem Rev. 2017 Dec 27;117(24):14091-14200. doi: 10.1021/acs.chemrev.7b00343. Epub 2017 Nov 22.

Propargylamines are a versatile class of compounds which find broad application in many fields of chemistry. This review aims to describe the different strategies developed so far for the synthesis of propargylamines and their derivatives as well as to...

Investigating FAM-N pulses for signal enhancement in MQMAS NMR of quadrupolar nuclei.

Solid state nuclear magnetic resonance

Colaux H, Dawson DM, Ashbrook SE.
PMID: 28131696
Solid State Nucl Magn Reson. 2017 Jul - Aug;84:89-102. doi: 10.1016/j.ssnmr.2017.01.001. Epub 2017 Jan 18.

Although a popular choice for obtaining high-resolution solid-state NMR spectra of quadrupolar nuclei, the inherently low sensitivity of the multiple-quantum magic-angle spinning (MQMAS) experiment has limited its application for nuclei with low receptivity or when the available sample volume...

Mapping urban greenspace use from mobile phone GPS data.
