On the complexity of multiplication in the IwahoriHecke algebra of the symmetric group
(Elsevier, 20160912)We present new efficient data structures for elements of Coxeter groups of type Am and their associated Iwahori Hecke algebras H(A(m)). Usually, elements of H(A(m)) are represented as simple coefficient list of length M = ... 
On the composition product of saturated fusion systems
(Elsevier, 201111)We say that a fusion system is the composition product of two subsystems if every morphism can be factored as a morphism in one fusion system followed by a morphism in the other. We establish a relationship between the ... 
On the equivariant Khomology of PSL_2 of the imaginary quadratic integers
(Association des Annales de l'Institut Fourier, 201609)We establish formulae for the part due to torsion of the equivariant $K$homology of all the Bianchi groups (PSL$_2$ of the imaginary quadratic integers), in terms of elementary numbertheoretic quantities. To achieve this, ... 
On the quiver presentation of the descent algebra of the symmetric group
(Elsevier, 20130318)We describe a presentation of the descent algebra of the symmetric group G(n) as a quiver with relations. This presentation arises from a new construction of the descent algebra as a homomorphic image of an algebra of ... 
On the rectilinear shear of compressible and incompressible elastic slabs
(2010)We review some pseudoplanar deformations for the equations of incompressible isotropic nonlinear elasticity first introduced in 1985 by Rajagopal and Wineman. We extend this class of deformations to compressible isotropic ... 
On the table of marks of a direct product of finite groups
(Elsevier, 20171228)We present a method for computing the table of marks of a direct product of finite groups. In contrast to the character table of a direct product of two finite groups, its table of marks is not simply the Kronecker product ... 
On the third and fourthorder constants of incompressible isotropic elasticity.
(Acoustical Society of America, 20100425)Consider the constitutive law for an isotropic elastic solid with the strainenergy function expanded up to the fourth order in the strain and the stress up to the third order in the strain. The stressstrain relation can ... 
On the Torus degeneration of the genus two partition function
(World Scientific Publishing, 20130716)We consider the partition function of a general vertex operator algebra V on a genus two Riemann surface formed by sewing together two tori. We consider the nontrivial degeneration limit where one torus is pinched down ... 
On the use of 31P NMR for the quantification of hydrosoluble phosphoruscontaining compounds in coral host tissues and cultured zooxanthellae
(Nature Publishing Group, 20160223)31P Nuclear Magnetic Resonance (NMR) was assessed to investigate the phosphoruscontaining compounds present in the tissues of the scleractinian coral Stylophora pistillata as well as of cultured zooxanthellae (CZ). Results ... 
Onde de Love Piézoacoustique
(20060424)Une sélection de résultats analytiques et numériques concernant la propagation d'ondes planes harmoniques guidées dans un bicouche piézoélectrique est présentée. L'étude effectuée concerne les modes transverses horizontaux ... 
Onepot hydrogen peroxide and hydrohalic acid induced ring closure and selective aromatic halogenation to give new ringfused benzimidazoles
(American Chemical Society, 20150519)A new series of selectively dichlorinated and dibrominated five to eightmemberedring [1,2a]fused benzimidazoles and [1,4]oxazino[4,3a]benzimidazoles are synthesized in mostly high yields of >80% using the reaction ... 
Onset of nonlinearity in the elastic bending of blocks
(American Society of Mechanical Engineers, 20130125)The classical flexure problem of nonlinear incompressible elasticity is revisited assuming that the bending angle suffered by the block is specified instead of the usual applied moment. The general momentbending angle ... 
Optical Observations of PSR J0205+6449
(2008)PSR J0205+6449 is a Xray and radio pulsar in supernova remnant 3C 58. We report on observations of the central region of 3C 58 using the 4.2m William Herschel Telescope with the intention of identifying the optical ... 
Optical pulsations from the anomalous Xray pulsar 1E 1048.15937
(2009)We present highspeed optical photometry of the anomalous Xray pulsar 1E 1048.15937 obtained with ULTRACAM on the 8.2m Very Large Telescope in June 2007. We detect 1E 1048.15937 at a magnitude of i'=25.3+/0.2, consistent ... 
Optimization of a hydrogen combustion mechanism using both direct and indirect measurements
(Elsevier ScienceDirect, 20140705)The Keromnes et al. (2013) mechanism for hydrogen combustion has been optimized using a large set of indirect experimental data, consisting of ignition measurements in shock tubes (566 datapoints in 43 datasets) and rapid ... 
Optimized reaction mechanism rate rules for ignition of normal alkanes
(Elsevier, 20160810)The increasing demand for cleaner combustion and reduced greenhouse gas emissions motivates research on the combustion of hydrocarbon fuels and their surrogates. Accurate detailed chemical kinetic models are an important ... 
The oxidation of 2butene: A high pressure ignition delay, kinetic modeling study and reactivity comparison with isobutene and 1butene
(Elsevier, 20160616)Butenes are intermediates ubiquitously formed by decomposition and oxidation of larger hydrocarbons (e.g. alkanes) or alcohols present in conventional or reformulated fuels. In this study, a series of novel ignition delay ... 
Oxidation of ethyleneair mixtures at elevated pressures, part 1: experimental results
(American Institute of Aeronautics and Astronautics, 20140326)Shocktube experiments have been performed to determine ignition delay times of undiluted ethylene air mixtures for temperatures from 1003 to 1401 K, at equivalence ratios from 0.3 to 2.0, and at pressures from 1.1 to 24.9 ... 
Oxidation of ethyleneair mixtures at elevated pressures, part 2: chemical kinetics
(American Institute of Aeronautics and Astronautics, 20140327)A chemical kinetics submechanism for small molecular weight hydrocarbons was modified by adjusting rate constants to produce better agreement with recent ethylene ignition delay time data compared with an earlier version ... 
Oxidative stress induced by Pt(IV) prodrugs based on the cisplatin scaffold and indole carboxylic acids in axial position
(Nature Publishing Group, 20160611)The use of Pt(IV) complexes as prodrugs that are activated by intracellular reduction is a widely investigated approach to overcome the limitations of Pt(II) anticancer agents. A series of ten mono and biscarboxylated ...
