The characteristics of squall lines in the Southeast Asia region

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Squall lines over the Maritime Continent were analysed using 20 years of IMERG GPM data and classified into four regional clusters. Significant regional differences were found in their size, intensity, lifespan, and propagation. Nighttime squall lines are primarily driven by the convergence of opposing offshore flows and the convergence of monsoonal ...

Why Autonomous Vehicles Are Not Ready Yet: A Multi‐Disciplinary Review of Problems, Attempted Solutions, and Future Directions

Journal of Field Robotics, EarlyView.
ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...

Identification of initial vegetation and habitat changes in small temperate fens using remote sensing

Remote Sensing in Ecology and Conservation, EarlyView.
Temperate fens with only incipient, subtle signs of deterioration can be reliably identified using Sentinel‐2 and aerial imagery, which sensitively detect early productivity‐related structural changes. Abstract Small temperate fens rank among the most endangered habitats in temperate Europe.

Non‐Invasive Scalp Tape‐Strip RNA Sequencing Captures Disease Activity and Treatment‐Response Signatures in Alopecia Areata

Allergy, EarlyView.
Non‐invasive scalp tape‐strip RNA sequencing captures core immune and follicular molecular signatures in alopecia areata. Tape‐strip transcriptomic profiles reflect disease severity and treatment response to baricitinib, with concordance to scalp biopsy‐derived signatures.

Comparative Analysis of the Performances of a Nonlinear Observer and Nonlinear Kalman Filters in the Presence of Non‐Gaussian Disturbances

International Journal of Robust and Nonlinear Control, Volume 36, Issue 7, Page 3896-3913, 10 May 2026.
ABSTRACT This paper focuses on state estimation for a fairly general class of systems, involving nonlinear functions and disturbances in both the process dynamics and output equations. A nonlinear observer that satisfies a H∞$$ {\boldsymbol{H}}_{\boldsymbol{\infty}} $$ disturbance attenuation constraint in addition to providing asymptotic stability in ...

Ultra-Wide Swath SAR Imaging With Continuous PRF Variation [PDF]

, 2010
Innovative multi-channel synthetic aperture radar (SAR) concepts enable high-resolution wide-swath imaging, but the antenna length typically restricts the achievable swath width.
