Scalar evolution equations for shear waves in incompressible solids: a simple derivation of the Z, ZK, KZK and KP equations
(The Royal Society, 20110708)We study the propagation of twodimensional finiteamplitude shear waves in a nonlinear prestrained incompressible solid, and derive several asymptotic amplitude equations in a simple, consistent and rigorous manner. The ... 
Scaling behavior of polymers at liquid/liquid interfaces
(American Chemical Society, 20150914)The dynamics of a polymer chain confined in a soft 2D slit formed by two immiscible liquids is studied by means of molecular dynamics simulations. We show that the scaling behavior of a polymer confined between two liquids ... 
A search for CO+ in planetary nebulae
(2007)We have carried out a systematic search for the molecular ion CO+ in a sample of 8 protoplanetary and planetary nebulae in order to determine the origin of the unexpectedly strong HCO+ emission previously detected in these ... 
A Search for Dark Matter Annihilation with the Whipple 10m Telescope
(2008)We present observations of the dwarf galaxies Draco and Ursa Minor, the local group galaxies M32 and M33, and the globular cluster M15 conducted with the Whipple 10m gammaray telescope to search for the gammaray signature ... 
A search for optical bursts from RRAT J18191458: II. Simultaneous ULTRACAMLovell Telescope observations
(2011)The Rotating RAdio Transient (RRAT) J18191458 exhibits ~3 ms bursts in the radio every ~3 min, implying that it is visible for only ~1 per day. Assuming that the optical light behaves in a similar manner, long exposures ... 
A Search for Pulsed TeV Gamma Ray Emission from the Crab Pulsar
(1999)We present the results of a search for pulsed TeV emission from the Crab pulsar using the Whipple Observatory's 10m gammaray telescope. The direction of the Crab pulsar was observed for a total of 73.4 hours between 1994 ...

Seismic Rayleigh waves on an exponentially graded, orthotropic halfspace
(The Royal Society, 2007)Efforts at modelling the propagation of seismic waves in halfspaces with continuously varying properties have mostly been focused on shearhorizontal waves. Here, a sagittally polarized (Rayleigh type) wave travels along ... 
Seminonnegative matrix factorization with global statistical consistency for collaborative filtering
(2009)[no abstract available] 
Simple shear is not so simple
(201203)For homogeneous, isotropic, nonlinearly elastic materials, the form of the homogeneous deformation consistent with the application of a Cauchy shear stress is derived here for both compressible and incompressible materials. ... 
Simultaneous Multiwavelength Observations of Markarian 421 During Outburst
(2009)We report on the results of two coordinated multiwavelength campaigns that focused on the blazar Markarian 421 during its 2006 and 2008 outbursts. These campaigns obtained UV and Xray data using the XMMNewton satellite, ... 
Slight compressibility and sensitivity to changes in Poisson's ratio
(2012)Finite element simulations of rubbers and biological soft tissue usually assume that the material being deformed is slightly compressible. It is shown here that, in shearing deformations, the corresponding normal stress ... 
Small amplitude waves and stability for a prestressed viscoelastic solid
(Springer, 2009)We study the propagation of small amplitude waves superimposed on a large static deformation in a nonlinear viscoelastic material of differential type. We use bulk waves and surface waves to address the questions of ... 
SnCl4 and TiCl4catalyzed anomerization of acylated O and SGlycosides: analysis of factors that lead to higher alpha:beta anomer ratios and reaction rates
(American Chemical Society, 20100913)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 alphaO and alphaSglycolipids is discussed ... 
Solitary and compactlike shear waves in the bulk of solids
(American Physical Society, 200606)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 ... 
Some design considerations for polymerfree drugeluting stents: a mathematical approach
(Elsevier (Science Direct), 2015)In this paper we provide the first model of drug elution from polymerfree arterial drugeluting stents. The generalised model is capable of predicting the drug release from a number of polymerfree 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 HaradaNorton, Held, $M_{12}$ and $L_3(3)$ simple groups based on certain orbifolding ...
