Mining social networks using heat diffusion processes for marketing candidates selection
(ACM, 2008)Social Network Marketing techniques employ pre-existing social networks to increase brands or products awareness through word-of-mouth promotion. Full understanding of social network marketing and the potential candidates ... -
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, ... -
Models for overdispersed data in entomology
(Springer, Cham, 2014-09-17)Entomological data are often overdispersed, characterised by a larger variance than assumed by simple standard models. It is important to model overdispersion properly in order to avoid incorrect and misleading inferences. ... -
Modified multiplicative decomposition model for tissue growth: Beyond the initial stress-free state
(Elsevier, 2018-05-19)The multiplicative decomposition model is widely employed for predicting residual stresses and morphologies of biological tissues due to growth. However, it relies on the assumption that the tissue is initially in a ... -
Monstrous and Generalized Moonshine and Permutation Orbifolds
(2008)We consider the application of permutation orbifold constructions towards a new possible understanding of the genus zero property in Monstrous and Generalized Moonshine. We describe a theory of twisted Hecke operators in ... -
Multi-sector approximation method for arteries: the residual stresses of circumferential rings with non-trivial openings
(The Royal Society, 2019-07-24)The opening angle method is a popular choice in biomechanics to estimate residual stresses in arteries. Experimentally, it means that an artery is cut into rings; then the rings are cut axially or radially allowing them ... -
Multiples of Pfister forms
(Elsevier, 2016-03-01)The isotropy of multiples of Pfister forms is studied. Some classical results are recalled and their consequences presented, with certain of these statements being previously known but hitherto unpublished. In particular, ... -
N=2 and N=4 subalgebras of super vertex operator algebras
(IOP Publishing, 2018-01-10)We develop criteria to decide if an N=2 or N=4 super conformal algebra is a subalgebra of a super vertex operator algebra in general, and of a super lattice theory in particular. We give some specific examples. -
Nash Equilibria in certain two-choice multi-player games played on the ladder graph
(World Scientific Publishing, 2021-01-16)In this paper, we compute analytically the number of Nash Equilibria (NE) for a two-choice game played on a (circular) ladder graph with 2n players. We consider a set of games with generic payoff parameters, with the only ... -
NHDC and PHDC: Non-propagating and propagating heat diffusion classifiers
(12th International Conference on Neural Information Processing, 2005)Abstract - By imitating the way that heat flows in a medium with a geometric structure, we propose two novel classification algorithms, Non-propagating Heat Diffusion Classifier (NHDC) and Propagating Heat Diffusion ... -
Non-invasive evaluation of skin tension lines with elastic waves
(Wiley, 2017-11-20)Background: Since their discovery by Karl Langer in the 19th Century, Skin Tension Lines (STLs) have been used by surgeons to decide the location and orientation of an incision. Although these lines are patient-specific, ... -
Non-principal surface waves in deformed incompressible materials
(Elsevier, 2005)The Stroh formalism is applied to the analysis of infinitesimal surface wave propagation in a statically, finitely and homogeneously deformed isotropic half-space. The free surface is assumed to coincide with one of the ... -
Noninvasive measurement of local stress inside soft materials with programmed shear waves
(American Association for the Advancement of Science, 2023-03-08)Mechanical stresses across different length scales play a fundamental role in understanding biological systems¿ functions and engineering soft machines and devices. However, it is challenging to noninvasively probe local ... -
Nonlinear correction to the Euler buckling formula for compressed cylinders with guided-guided end conditions
(Springer, 2011-02)Euler's celebrated buckling formula gives the critical load N for the buckling of a slender cylindrical column with radius B and length L as N/([pi]^3 B^2 )=(E/4)(B/L)^2, where E is Young's modulus. Its derivation relies ... -
Nonlinear elastic vector solitons in hard-magnetic soft mechanical metamaterials
(Elsevier, 2023-07-14)We propose a design of a metamaterial for magnetically tunable propagation of nonlinear vector solitary waves. The metamaterial consists of a periodic array of units of hard-magnetic inclusion embedded in a soft matrix. ... -
Nonlinear Euler buckling
(Royal Society Publishing, 2008-11)The buckling of hyperelastic incompressible cylindrical tubes of arbitrary length and thickness under compressive axial load is considered within the framework of nonlinear elasticity. Analytical and numerical methods for ... -
Nonlinear response and axisymmetric wave propagation in functionally graded soft electro-active tubes
(Elsevier, 2020-10-02)Soft electro-active (SEA) materials can be designed and manufactured with gradients in their material properties, to modify and potentially improve their mechanical response in service. Here, we investigate the nonlinear ... -
Nonlinear transverse waves in deformed dispersive solids
(Elsevier, 2008)We present a phenomenological approach to dispersion in nonlinear elasticity. A simple, thermomechanically sound, constitutive model is proposed to describe the (non-dissipative) properties of a hyperelastic dispersive ... -
A note about waves in dissipative and dispersive solids
(World Scientific, 2008)We study shear waves propagating in a special viscoelastic model proposed first by Fosdick and Yu in 1996. We deduce an asymptotic approximation which reduces the full balance equations to a system of evolution equations ... -
A note on element centralizers in finite Coxeter groups
(De Gruyter, 2011-08-29)The normalizer N-W(W-J) of a standard parabolic subgroup W-J of a finite Coxeter group W splits over the parabolic subgroup with complement N-J consisting of certain minimal length coset representatives of W-J in W. In ...
