Developmental Science, Volume 29, Issue 4, July 2026.ABSTRACT Children are adept statistical learners, capable of parsing streams of structured input into meaningful units, but the cognitive processes they engage during learning may differ from those of adults. To date, however, it is unclear how learners of different ages predict upcoming experience when navigating environments with complex structure ...

GEODESIC TUBES AND SPACES OF CONSTANT CURVATURE [PDF]
application/pdfThis is a contribution to the general problem of how the properties of geodesic tubes on a Riemannian manifold ＄(M^{n}, g)＄ determine the geometry of the ambient space.

Conformal vector fields on Finsler spaces
, 2013 Here, it is shown that every vector field on a Finsler space which keeps geodesic circles invariant is conformal. A necessary and sufficient condition for a vector field to keep geodesic circles invariant, known as concircular vector fields, is obtained.

A relative Poincaré–Birkhoff theorem
Bulletin of the London Mathematical Society, Volume 58, Issue 7, July 2026.Abstract A. Moreno and Otto van Koert proved a generalised version of the classical Poincaré–Birkhoff theorem, for Liouville domains of any dimension. In this article, we prove a relative version for Lagrangians with Legendrian boundary. This gives interior chords of arbitrary large length, provided that the twist condition introduced by Moreno and van

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.Abstract Mesoscale convective systems (MCSs) are known to induce heavy rainfall and pose significant weather hazards in tropical and mid‐latitude regions. Understanding the environmental conditions of MCSs is essential for improving model simulations and operational precipitation forecasts.

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract The floods of 01 September 2009 in Ouagadougou, Burkina Faso, were among the most severe in the Central Sahel's history, highlighting the region's persistent flood risk. This extreme precipitation event (EPE) was influenced by various atmospheric drivers, including Convectively Coupled Equatorial Waves (CCEWs).

The geometry of inflationary observables: Lifts, flows, equivalence classes
Physics Letters BThe Eisenhart lift allows formulating the dynamics of a scalar field in a potential as pure geodesic motion in a curved field-space manifold involving an additional fictitious vector field. Making use of the formalism in the context of inflation, we show

Gradient Vector Flow Fast Geodesic Active Contours
, 2001 This paper proposes a new front propagation flow for boundary extraction. The proposed framework is inspired by the geodesic active contour model and leads to a paradigm that is relatively free from the initial curve position.

Seismic Evidence for Slab Tearing Beneath the Indo‐Myanmar Subduction Zone
Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract Slab tearing has been increasingly recognized as a key geodynamic process influencing the evolution of the eastern Himalayan syntaxis. However, whether, where and how the subducted Indian slab beneath the Indo‐Myanmar subduction zone has been torn remains poorly constrained.

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract We performed a stress tensor inversion using focal mechanisms from intermediate‐depth and deep earthquakes to estimate the stress regime of the Pacific slab beneath southwestern Japan. We focused on the temporally averaged stress field derived from the recent 28‐year data set of the F‐net CMT solutions.
