Cascades with Adjoint Matter: Adjoint Transitions [PDF]

Journal of High Energy Physics, 2011
A large class of duality cascades based on quivers arising from non-isolated singularities enjoy adjoint transitions - a phenomenon which occurs when the gauge coupling of a node possessing adjoint matter is driven to strong coupling in a manner ...

Response of the ozone-related health burden in Europe to changes in local anthropogenic emissions of ozone precursors

Environmental Research Letters, 2023
Exposure to ozone (O _3 ) is associated with many human health problems, resulting in tens of thousands of premature deaths annually in Europe. This study quantifies the impact of changes in anthropogenic emissions of O _3 precursors on premature deaths ...

Tête, épaule ou poitrine : est-ce que le positionnement des caméras portatives a une incidence sur la visibilité d’informations cruciales ?

Criminologie, 2021
Les caméras portatives sont devenues monnaie courante dans les forces de l’ordre. La plupart de la recherche sur le sujet s’est intéressée à l’effet des caméras sur le comportement des policiers et leur incidence sur le taux de plaintes des citoyens ...

Gradient-based optimization of spacecraft and aircraft thermal design

Aviation, 2020
Steady-case thermal analysis plays an important role in dimensioning thermal control systems for spacecrafts and aircrafts. Usually a trial and error approach is used based on engineering judgement and experience.

Solute Transport Control at Channel Junctions Using Adjoint Sensitivity

Mathematics, 2021
Water quality control and the control of contaminant spill in water in particular are becoming a primary need today. Gradient descent sensitivity methods based on the adjoint formulation have proved to be encouraging techniques in this context for river ...

Building Tangent‐Linear and Adjoint Models for Data Assimilation With Neural Networks

Journal of Advances in Modeling Earth Systems, 2021
We assess the ability of neural network emulators of physical parametrization schemes in numerical weather prediction models to aid in the construction of linearized models required by four‐dimensional variational (4D‐Var) data assimilation.

Adjoints, multi-adjoints, pluri-adjoints

Bulletin of the Belgian Mathematical Society - Simon Stevin, 1995
Let \((G_p: {\mathcal A}_p\to {\mathcal X})_{p\in P}\) be a small family of functors having left adjoints, between small categories. If \({\mathcal A}\) is the coproduct of \(({\mathcal A}_p )_{p\in P}\) in \({\mathcal C}at\), the functor \(G: {\mathcal A}\to {\mathcal X}\) defined by \((G_p )_{p\in P}\) is proved to have a left multiadjoint in the ...

Discrete adjoint approximations with shocks [PDF]

, 2002
This paper is concerned with the formulation and discretisation of adjoint equations when there are shocks in the underlying solution to the original nonlinear hyperbolic p.d.e. For the model problem of a scalar unsteady one-dimensional p.d.e.
