High‐Resolution Tomography for the Upper‐Mantle Structure in North China by Full‐Waveform Inversion of Teleseismic P Wave and Its Codas

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract We investigate the structure and tectonic environment in the crust and upper mantle beneath the North China Craton (NCC) by conducting a full‐waveform inversion of teleseismic P and its coda waves from densely distributed broadband seismic stations. A high‐resolution model involving P‐ and S‐wave velocities as well as density is constructed by

Airborne Observations Reveal Underestimated Riverine Methane Emissions Across the Amazon

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Strongly increasing trends in global methane in recent decades highlight the importance of understanding source‐sink attributions and climate feedback mechanisms, especially for large natural sources like wetlands. Here, we present an analysis of airborne methane observations above the Amazon Basin conducted from December 2022 through January ...

A new projection method for the optimal control of Navier-Stokes equations

四川大学学报. 自然科学版, 2016
In this paper, a new $L^2$ projection method is proposed for the optimal control of Navier-Stokes equations. The continuous equal-order conforming elements is employed.

Conjugate heat transfer shape optimization based on the continuous adjoint method

, 2017
In this paper, the continuous adjoint method for use in gradient-based op- timization methods for coupled problems including heat transfer between bodies (solids) and fluids flowing over or inside them is developed. This kind of problems are usually referred to as Conjugate Heat Transfer (CHT) problems.

Flow and transport parameter identification in porous media using the continuous adjoint method

, 2018
L’objectif de ce travail est le développement puis l’évaluation des capacités à inverser des modèles hydrologiques distribués (majoritairement écoulement et transport en milieu poreux fracturé) via la technique de l'état adjoint. L'état adjoint est en pratique une variable associée à un problème direct qui représenterait la variable d'état de ce ...
