A search for pulsations from Geminga above 100 GeV with VERITAS
(American Astronomical Society, 2015-02-10)
We present the results of 71.6 hr of observations of the Geminga pulsar (PSR J0633+1746) with the VERITAS very-high-energy gamma-ray telescope array. Data taken with VERITAS between 2007 November and 2013 February were ...
Sophisticated clean air strategies required to mitigate against particulate organic pollution
(Nature Publishing Group, 2017-03-17)
Since the 1980's, measures mitigating the impact of transboundary air pollution have been implemented successfully as evidenced in the 1980-2014 record of atmospheric sulphur pollution over the NE-Atlantic, a key region ...
Multivalent carbohydrate-lectin interactions: the way synthetic chemistry enables insights into nanometric recognition
(MDPI Open Access, 2016-05-13)
Glycan recognition by sugar receptors (lectins) is intimately involved in many aspects of cell physiology. However, the factors explaining the exquisite selectivity of their functional pairing are not yet fully understood. ...
The most powerful flaring activity from the NLSyl PMN J0948+0022
(Oxford University Press, 2015-01-21)
We report on multifrequency observations performed during 2012 December-2013 August of the first narrow-line Seyfert 1 galaxy detected in gamma-rays, PMN J0948+0022 (z = 0.5846). A y -ray flare was observed by the Large ...
Gamma-rays from the quasar PKS 1441+25: story of an escape
(2015-12-20)
Outbursts from gamma-ray quasars provide insights on the relativistic jets of active galactic nuclei and constraints on the diffuse radiation fields that fill the universe. The detection of significant emission above 100 ...
VERITAS observations of the BL Lac object PG 1553+113
(American Astronomical Society, 2015-01-20)
We present results from VERITAS observations of the BL Lac object PG 1553+113 spanning the years 2010, 2011, and 2012. The time-averaged spectrum, measured between 160 and 560 GeV, is well described by a power law with a ...
Investigation of depth-resolved nanoscale structural changes in regulated cell proliferation and chromatin decondensation
(2013)
We present depth-resolved spatial-domain low-coherence quantitative phase microscopy, a simple approach that utilizes coherence gating to construct a depth-resolved structural feature vector quantifying sub-resolution axial ...
VLT polarimetry observations of the middle-aged pulsar PSR B0656+14
(EDP Sciences, 2015-11-02)
Context. Optical polarisation measurements are key tests for different models of the pulsar magnetosphere. Furthermore, comparing the relative orientation of the phase-averaged linear polarisation direction and the pulsar ...
Cross platform standardisation of an experimental pipeline for use in the identification of dysregulated human circulating MiRNAs
(Public Library of Science, 2015-09-10)
Micro RNAs (miRNAs) are a class of highly conserved small non-coding RNAs that play an important part in the post-transcriptional regulation of gene expression. A substantial number of miRNAs have been proposed as biomarkers ...
Low-temperature anaerobic digestion is associated with differential methanogenic protein expression
(Oxford University Press, 2015-04-09)
Anaerobic digestion (AD) is an attractive wastewater treatment technology, leading to the generation of recoverable biofuel (methane). Most industrial AD applications, carry excessive heating costs, however, as AD reactors ...
