On Finsler spacetimes with a timelike Killing vector field [PDF]

, 2017
We study Finsler spacetimes and Killing vector fields taking care of the fact that the generalised metric tensor associated to the Lorentz–Finsler function L is in general well defined only on a subset of the slit tangent bundle.

Dengue NS1 antigen kit shows high sensitivity for detection of recombinant dengue virus-2 NS1 antigen spiked with Aedes aegypti mosquitoes

Scientific Reports, 2021
Dengue, caused by the dengue virus (DENV) is a significant vector-borne disease. In absence of a specific treatment and vaccine, dengue is becoming a rising threat to public health.

Nation-wide vector surveillance on Zika and Dengue did not indicate transmission of the American lineage-pandemic Zika virus in India

International Journal of Infectious Diseases, 2021
Objectives: Following the Public Health Emergency of International Concern declared on Zika by the World Health Organization during 2016, the Indian Council of Medical Research carried out nationwide vector surveillance for Zika and Dengue viruses (ZIKV ...

Parallel vector fields [PDF]

Proceedings of the American Mathematical Society, 1965
We speak of a parallel vector field if parallel transport is independent of the path of propagation [1, p. 239]. Riemannian spaces which are flat offer a simple example for the existence of such fields [1, p. 239]. We wish to generalize the concept of parallel displacement of a vector in a Riemannian space.

Black holes with a single Killing vector field: black resonators [PDF]

Journal of High Energy Physics, 2015
We numerically construct asymptotically anti-de Sitter (AdS) black holes in four dimensions that contain only a single Killing vector field. These solutions, which we coin black resonators, link the superradiant instability of Kerr-AdS to the nonlinear ...

Ectoparasites Diversity on Rodents and Shrews at Scrub Typhus Endemic Vellore District of Tamil Nadu, India

Journal of Arthropod-Borne Diseases, 2022
Background: Rodents and shrew living in the vicinity of human beings perform significant role to harbor different spe­cies of ectoparasites and thus act as the reservoir host for the spread of diseases to human and animals.

Chikungunya virus outbreak in Kerala, India, 2007: a seroprevalence study

Memorias do Instituto Oswaldo Cruz, 2011
India was affected by a major outbreak of chikungunya fever caused by Chikungunya virus (CHIKV) during 2006-2007. Kerala was the worst affected state during 2007 with a contribution of 55.8% suspected cases in the country.

Generalized Proca action for an Abelian vector field [PDF]

, 2015
We revisit the most general theory for a massive vector field with derivative self-interactions, extending previous works on the subject to account for terms having trivial total derivative interactions for the longitudinal mode.

Field theories with a vector global symmetry [PDF]

SciPost Physics, 2019
Motivated by recent discussions of fractons, we explore nonrelativistic field theories with a continuous global symmetry, whose charge is a spatial vector. We present several such symmetries and demonstrate them in concrete examples.

Small Data Solutions of the Vlasov-Poisson System and the Vector Field Method [PDF]

, 2015
The aim of this article is to demonstrate how the vector field method of Klainerman can be adapted to the study of transport equations. After an illustration of the method for the free transport operator, we apply the vector field method to the Vlasov ...
