Cascades with Adjoint Matter: Adjoint Transitions [PDF]

open access: yesJournal 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 ...

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

open access: yesJournal 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.

Symmetries and strings of adjoint QCD2 [PDF]

open access: yesJournal of High Energy Physics, 2020
We revisit the symmetries of massless two-dimensional adjoint QCD with gauge group SU(N). The dynamics is not sufficiently constrained by the ordinary symmetries and anomalies.

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

open access: yesEnvironmental 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 ...

A discrete adjoint based level set topology optimization method for stress constraints

open access: yesComputer Methods in Applied Mechanics and Engineering, 2021
This paper proposes a new methodology for computing boundary sensitivities in level set topology optimization using the discrete adjoint method. The adjoint equations are constructed using the discretized governing field equations. The objective function

Global adjoint tomography—model GLAD-M25

open access: yesGeophysical Journal International, 2020
Building on global adjoint tomography model GLAD-M15, we present transversely isotropic global model GLAD-M25, which is the result of 10 quasi-Newton tomographic iterations with an earthquake database consisting of 1480 events in the magnitude range 5 ...

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

open access: yesCriminologie, 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 ...

Adjoint Method and Inverse Design for Nonlinear Nanophotonic Devices [PDF]

open access: yesACS Photonics, 2018
The development of inverse design, where computational optimization techniques are used to design devices based on certain specifications, has led to the discovery of many compact, non-intuitive structures with superior performance. Among various methods,

Gradient-based optimization of spacecraft and aircraft thermal design

open access: yesAviation, 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.
