Viral vector platforms within the gene therapy landscape

open access: yesSignal Transduction and Targeted Therapy, 2021
Throughout its 40-year history, the field of gene therapy has been marked by many transitions. It has seen great strides in combating human disease, has given hope to patients and families with limited treatment options, but has also been subject to many

A vector field method for relativistic transport equations with applications [PDF]

open access: yes, 2015
We adapt the vector field method of Klainerman to the study of relativistic transport equations. First, we prove robust decay estimates for velocity averages of solutions to the relativistic massive and massless transport equations, without any compact ...

Pathogen change of avian influenza virus in the live poultry market before and after vaccination of poultry in southern China

open access: yesVirology Journal, 2021
Background The fifth wave of H7N9 avian influenza virus caused a large number of human infections and a large number of poultry deaths in China. Since September 2017, mainland China has begun to vaccinate poultry with H5 + H7 avian influenza vaccine.

Impact of SA 14-14-2 vaccination on the occurrence of Japanese encephalitis in India

open access: yesHuman 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

Multi-country evaluation of the durability of pyrethroid plus piperonyl-butoxide insecticide-treated nets: study protocol

open access: yesMalaria 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

Event-Selected Vector Field Discontinuities Yield Piecewise-Differentiable Flows [PDF]

open access: yesSIAM Journal on Applied Dynamical Systems, 2014
We study a class of discontinuous vector fields brought to our attention by multilegged animal locomotion. Such vector fields arise not only in biomechanics, but also in robotics, neuroscience, and electrical engineering, to name a few domains of ...

Rotated Vector Fields

open access: yesJournal of Differential Equations, 1993
In \S1 of this paper the author generalizes the theory of rotated vector fields of G. F. D. Duff to rotated vector fields \[ \dot x=f_ 1(x,y,\lambda), \qquad \dot y=f_ 2(x,y,\lambda) \tag{\(1_ \lambda\)} \] where \(\lambda\in R\), \(f_ i\) and \(G\) are analytic, and no cycle of \((1_ \lambda)\) is congruent to a branch of \(G(x,y)=0\); he proves that ...

A Vector Field Approach to Estimating Environmental Exposure Using Human Activity Data

open access: yesISPRS International Journal of Geo-Information, 2022
Environmental exposure of people plays an important role in assessing the quality of human life. The most existing methods that estimate the environmental exposure either focus on the individual level or do not consider human mobility.
