Vector fields on spheres [PDF]
The Annals of Mathematics, 1962 The question of vector fields on spheres arises in homotopy theory and in the theory of fibre bundles, and it presents a classical problem, which may be explained as follows. For each n, let Sn-I be the unit sphere in euclidean n-space Rn. A vector field on Sn-1 is a continuous function v assigning to each point x of Sn-1 a vector v(x) tangent to Sn-1 ...

Towards a sterile insect technique field release of
, 2008 Background The work described in this article forms part of a study to suppress a population of the malaria vector Anopheles arabiensis in Northern State, Sudan, with the Sterile Insect Technique. No data have previously been collected on the irradiation

Finite element method using vector finite elements applied to eddy current problems [PDF]
, 2011 Vector fields found in electromagnetics are fundamentally different to vector fields found in other research areas such as structural mechanics. Electromagnetic vector fields possess different physical behaviour patterns and different properties in ...

Impact of SA 14-14-2 vaccination on the occurrence of Japanese encephalitis in India
Human Vaccines & Immunotherapeutics, 2019 Japanese encephalitis virus is the major cause of encephalitis in India. To control the increasing incidence and fatal outbreaks, SA 14-14-2 vaccine was introduced initially in 104 endemic districts in phased manner from 2006 to 2011. As there is no data

On Regularized Reconstruction of Vector Fields [PDF]
IEEE Transactions on Image Processing, 2011 In this paper, we give a general characterization of regularization functionals for vector field reconstruction, based on the requirement that the said functionals satisfy certain geometric invariance properties with respect to transformations of the coordinate system.

VECTOR FIELD AND INFLATION [PDF]
International Journal of Modern Physics: Conference Series, 2011 We have investigated if the vector field can give rise to an accelerating phase in the early universe. We consider a timelike vector field with a general quadratic kinetic term in order to preserve an isotropic background spacetime. The vector field potential is required to satisfy the three minimal conditions for successful inflation: i) ρ > 0, ii)

Bifurcations of Optimal Vector Fields [PDF]
Mathematics of Operations Research, 2015 We study the structure of the solution set of a class of infinite-horizon dynamic programming problems with one-dimensional state spaces, as well as their bifurcations, as problem parameters are varied. The solutions are represented as the integral curves of a multivalued optimal vector field on state space.

Malaria Journal, 2023 Background Mass distributions of long-lasting insecticidal nets (LLINs) have contributed to large reductions in the malaria burden. However, this success is in jeopardy due in part to the increasing pyrethroid-resistant mosquito population as well as low
