Covariance of the intertropical discontinuity and African easterly jet in Sahelian wet and dry years
Intertropical discontinuity and African easterly jet (AEJ) positions are strongly correlated, with a more pronounced linear relationship across wet years. Surface heat flux anomalies modify low‐level temperature and sensible heat flux gradients that shift the AEJ core south of the gradient maxima in both composites.

Intensity dependence of El Niño and La Niña evolution and mixed‐layer heat‐budget processes
El Niño–Southern Oscillation (ENSO) intensity modulates the spatial, temporal, and dynamical evolution of events strongly. El Niño SST anomalies shift westward with decreasing intensity, while La Niña anomalies remain spatially fixed. Stronger events initiate earlier and persist longer than weak events.

A structurally localized ensemble Kalman filtering approach
We derive an inherently localized ensemble Kalman filtering (EnKF) approach, avoiding the need for any auxiliary localization technique. The idea is to first use the variational Bayesian optimization to approximate the (continuous) state analysis probability density function (pdf) by a product of independent marginal pdfs corresponding to small ...

ABSTRACT Regulated rivers represent complex hydrological systems where groundwater–surface water interactions are governed by natural conditions and human interventions. This study investigates the spatiotemporal dynamics of groundwater–surface water exchanges in the Nechako River, British Columbia (Canada), using numerical simulations.

Prebending of 304L/Q345R cladded plates significantly alters the subsequent weld thermal cycle and modifies the local interfacial microstructure. Combined electron backscatter diffraction (EBSD) and microscopy analysis demonstrates that deformation twinning, martensitic transformation, and defect initiation are concentrated at the trimaterial junction,

A retrospective on the 2025 Atlantic hurricane season
The 2025 Atlantic hurricane season was intermittent, with extended quiet periods separated by three clusters of activity. The broad‐scale conditions were often unfavourable for cyclogenesis and common drivers of activity such as La Niña were weak, but well above‐average sea temperatures still supported intense storms.

A Novel Multidisciplinary Approach for Reptile Movement and Behavior Analysis
We present a novel multidisciplinary approach capable of advancing research on reptiles’ behavior. Our approach uses integrated tools and methods for the digitization, reconstruction, and visualization of reptiles and their behavior. We (i) record movement through tri‐axial accelerometers, video cameras, and motion capture systems; (ii) ground‐truth ...

Quasi–Newton updates for Preconditioned Nonlinear Conjugate Gradient methods
In this paper we study new preconditioners for the Nonlinear Conjugate Gradient (NCG) method in large scale unconstrained optimization. Our preconditioners are based on quasi--Newton updates, which approximate the inverse of the Hessian matrix. In particular, we consider a couple of new low-rank quasi-Newton symmetric updating formulae.

We aimed to report the existence and profile of group 9 innate lymphoid cells (ILC9s). Overall, ILC9 proportions in AR patients show differences compared to healthy subjects and responder SCIT patients. IL‐9 expression decreases after siRNA inhibition of Bach2 suggesting Bach2 could display as a transcription factor of ILC9.
