Snake venom potency and yield are associated with prey‐evolution, predator metabolism and habitat structure
(Wiley, 2019-01-07)Snake venom is well known for its ability to incapacitate and kill prey. Yet, potency and the amount of venom available varies greatly across species, ranging from the seemingly harmless to those capable of killing vast ... -
SnCl4- and TiCl4-catalyzed anomerization of acylated O- and S-Glycosides: analysis of factors that lead to higher alpha:beta anomer ratios and reaction rates
(American Chemical Society, 2010-09-13)The quantification of factors that influence both rates and stereoselectivity of anomerization reactions catalyzed by SnCl4 and TiCl4 and how this has informed the synthesis of alpha-O- and alpha-S-glycolipids is discussed ... -
Solid-state transformations of sulfathiazole polymorphs: The effects of milling and humidity
(American Chemical Society, 2013-07-11)The effect of milling on the transitions of sulfathiazole polymorphs in the absence and presence of solvent and excipients was monitored by X-ray powder diffraction (XRPD), attenuated total reflectance infrared (ATR-IR), ... -
Solitary and compact-like shear waves in the bulk of solids
(American Physical Society, 2006-06)We show that a model proposed by Rubin, Rosenau and Gottlieb J. Appl. Phys. 77 4054 (1995) for dispersion caused by an inherent material characteristic length belongs to the class of simple materials. Therefore, it is ... -
Solvothermal synthesis of discrete cages and extended networks comprising {Cr(III)3O(O2CR)3(oxime)3}2- (R = H, CH3, C(CH3)3, C14H9) building blocks
(Royal Society of Chemistry, 2016-07-28)The synthesis, structural and magnetic characterisation of a family of related Cr(III) cages are reported. Each member comprises {Cr(III)3O(O2CR1)3(R2-sao)3}2- (R1 = H, CH3, C(CH3)3, C14H9 ; R2 = Me, Ph, tBu, C10H8) triangles ... -
Some design considerations for polymer-free drug-eluting stents: a mathematical approach
(Elsevier (Science Direct), 2015)In this paper we provide the first model of drug elution from polymer-free arterial drug-eluting stents. The generalised model is capable of predicting the drug release from a number of polymer-free systems including those ... -
Some Generalizations of the MacMahon Master Theorem
(2011)We consider a number of generalizations of the $\beta$-extended MacMahon Master Theorem for a matrix. The generalizations are based on replacing permutations on multisets formed from matrix indices by partial permutations ... -
Some Irrational Generalised Moonshine from Orbifolds
(2002)We verify the Generalised Moonshine conjectures for some irrational modular functions for the Monster centralisers related to the Harada-Norton, Held, $M_{12}$ and $L_3(3)$ simple groups based on certain orbifolding ... -
Some results on finite amplitude elastic waves propagating in rotating media
(Springer, 2004-12)Two questions related to elastic motions are raised and addressed. First: in which theoretical framework can the equations of motion be written for an elastic half-space put into uniform rotation? It is seen that nonlinear ... -
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 ... -
Sorec: social recommendation using probabilistic matrix factorization
(ACM, 2008)Data sparsity, scalability and prediction quality have been recognized as the three most crucial challenges that every collaborative filtering algorithm or recommender system confronts. Many existing approaches to recommender ... -
Spatial frequency domain correlation mapping optical coherence tomography for nanoscale structural characterization
(AIP Publishing, 2019-09-16)Most of the fundamental pathological processes in living tissues exhibit changes at the nanoscale. Noninvasive, label-free detection of structural changes in biological samples pose a significant challenge to both researchers ... -
Species measurements of the particulate matter reducing additive tri–propylene glycol monomethyl ether
(Elsevier, 2018-07-23)Reducing particulate matter formation and emissions by using fuel additives is a topic of interest for the petrochemical and automotive engineering industries. A compound which has been shown to be effective in this regard ... -
Specificity and sensitivity evaluation of novel and existing Bacteroidales and Bifidobacteria-specific PCR assays on feces and sewage samples and their application for microbial source tracking in Ireland
(Elsevier, 2009)Three novel ruminant-specific PCR assays, an existing ruminant-specific PCR assay and five existing human-specific PCR assays, which target 16S rDNA from Bacteroidales or Bifidobacteria, were evaluated. The assays were ... -
Spectral encoding of spatial frequency approach for characterization of nanoscale structures
(American Institute of Physics, 2012-07-17)An approach to acquire axial structural information at nanoscale is demonstrated. It is based on spectral encoding of spatial frequency principle to reconstruct the structural information about the axial profile of the ... -
The speed of interfacial waves polarized in a symmetry plane
(Elsevier, 2006-01)The surface-impedance matrix method is used to study interfacial waves polarized in a plane of symmetry of anisotropic elastic materials. Although the corresponding Stroh polynomial is a quartic, it turns out to be ... -
Spherulization as a process for the exudation of chemical cues by the encrusting sponge C. crambe
(Nature Publishing Group, 2016-07-06)Ecological interactions in the marine environment are now recognized to be partly held by chemical cues produced by marine organisms. In particular, sponges are sessile animals thought to rely on the bioactive substances ... -
Spontaneous solid-state cocrystallization of caffeine and urea
(American Chemical Society, 2020-01-09)The cocrystallization of caffeine and urea was monitored and analyzed using infrared spectroscopy, Raman microscopy, scanning electron microscopy, differential scanning calorimetry, and X-ray diffraction. The caffeine-urea ... -
