Summertime primary and secondary contributions to Southern Ocean cloud condensation nuclei
(Nature Research (part of Springer Nature), 2019-07-18)
Atmospheric aerosols in clean remote oceanic regions contribute significantly to the global albedo through the formation of haze and cloud layers; however, the relative importance of ‘primary’ wind-produced sea-spray over ...
Global and local tests to assess stationarity of Markov transition models
(Taylor & Francis, 2018-02-09)
We present global and local likelihood-based tests to evaluate stationarity in transition models. Three motivational studies are considered. A simulation study was carried out to assess the performance of the proposed ...
On stress-dependent elastic moduli and wave speeds
(Oxford Journals, 2012-03-30)
On the basis of the general non-linear theory of a hyperelastic material with initial stress, initially without consideration of the origin of the initial stress, we determine explicit expressions for the stress-dependent ...
The mod 2 cohomology rings of SL2 of the imaginary quadratic integers
(Elsevier ScienceDirect, 2015-09-28)
We establish general dimension formulae for the second page of the equivariant spectral sequence of the action of the SL2 groups over imaginary quadratic integers on their associated symmetric space. By way of doing this, ...
Low Temperature Fluorescence Studies of Crude Petroleum Oils
(2011)
We have studied the low-temperature (133-298 K) fluorescence emission of crude petroleum oils using a combination of steady-state and time-resolved measurements. This was done, first, to see if we could generate linear ...
RNA from a simple-tandem repeat is required for sperm maturation and male fertility in Drosophila melanogaster
(eLife Sciences Publications, 2019-11-05)
Tandemly-repeated DNAs, or satellites, are enriched in heterochromatic regions of eukaryotic genomes and contribute to nuclear structure and function. Some satellites are transcribed, but we lack direct evidence that ...
Generation of a panel of high affinity antibodies and development of a biosensor-based immunoassay for the detection of okadaic acid in shellfish
(Elsevier, 2015-07-10)
Okadaic acid (OA) and its derivatives, DTX-1 and DTX-2, are marine biotoxins associated with diarrhetic shellfish poisoning. Routine monitoring of these toxins relies on the mouse bioassay. However, due to the technical ...
Simulation of quantum circuits by low-rank stabilizer decompositions
(Verein zur Förderung des Open Access Publizierens in den Quantenwissenschaften, 2019-09-02)
Recent work has explored using the stabilizer formalism to classically simulate quantum circuits containing a few non-Clifford gates. The computational cost of such methods is directly related to the notion of

Actively controllable topological phase transition in phononic beam systems
(Elsevier, 2020-05-01)
Topological insulators, which allow edge or interface waves but forbid bulk waves, have revolutionized our scientific cognition of acoustic/elastic systems. Due to their nontrivial topological characteristics, edge (interface) ...
Stability analysis of charge-controlled soft dielectric plates
(Elsevier, 2020-04-06)
We examine the stability of a soft dielectric plate deformed by the coupled effects of a mechanical pre-stress applied on its lateral faces and an electric field applied through its thickness under charge control. The ...
