The Daily Atmospheric Ionospheric Limb Imager (DAILI) CubeSat Experiment

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract The Daily Atmospheric Ionospheric Limb Imager (DAILI) (Daily Atmospheric and Ionospheric Limb Imager) mission utilized a 6U CubeSat, deployed at about 410 km altitude in a 51‐degree orbit, to make simultaneous daytime limb measurements in two colors; at 630 nm to measure the OI (630 nm) redline and at 765 nm to measure the O2 ${\mathrm{O}}_{2}$

Effect of Guide Vane Pitch Circle Diameter on Pressure Fluctuation in Vaneless Zone of Francis Turbine

Journal of Applied Fluid Mechanics, 2020
In a Francis turbine, the guide vanes are arranged in the direction of flow behind the stay vanes. And as it is generally believed that the outlet angle of water after it flows through the spiral case and stay vanes is fixed, the flow and flow ...

Conceptual Model of the Debarking Process of Large Wood in Rivers

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract When transported in rivers by short‐term episodic events such as floods and debris flows, large wood interacts with the flow, sediment, and river boundaries, leading to physical degradation such as weathering, abrasion, and breakage. This degradation, manifested as mass loss and structural alteration, weakens wood stability, increases mobility,

Surface‐State Controls on Dust Emission Variability in Lower Mesopotamia and Kuwait Using Field and Multi‐High‐Resolution Satellite Data

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 9, September 2026.
Abstract Aeolian dust strongly influences climate, air quality, and biogeochemical cycles, yet identifying source areas and determining their surface‐state controls remain challenging. We focus on lower Mesopotamia and Kuwait, a globally significant dust source region where surface characteristics of dust sources remain poorly understood through ...

Simulation and Test for Two Airfoils with Wind Guide Vane of VAWT

, 2010
Two airfoils of vertical axis wind turbine (VAWT) were designed, and the wind guide vane was added for VAWT. By using Fluent and the environment wind tunnel, some results were simulated and tested for two different types of airfoils and its wind guide ...

A Mechanism‐Based Framework for Anti‐Aging Strategies: From Metabolic Regulation to Senotherapy and Stem Cell‐Based Interventions

Aging Cell, Volume 25, Issue 9, September 2026.
The aging of the human body is a complex process driven by multiple contributing factors. Based on their underlying mechanisms, current anti‐aging interventions can be classified into six primary categories. This paper summarizes the most promising anti‐aging strategies within each class. ABSTRACT The global prevalence of aging and age‐related diseases

Learning From Crushing Failures: Changes in Physical Properties Reveal the Mechanics of Submarine Carbonate Landslides

Basin Research, Volume 38, Issue 5, September‐October 2026.
Changes in the physical properties of calcareous ooze between intact weak layers and glide planes within the same stratigraphy provide new constraints on the deformation processes and mechanical factors that control the mobility and erosive behaviour of submarine carbonate landslides.

Associations Between Paternal Sensitivity and Cognitive and Behavioural Outcomes in Preterm Children: An Individual Participant Data Meta‐Analysis

Child: Care, Health and Development, Volume 52, Issue 5, September 2026.
ABSTRACT Background Children born preterm (PT) face elevated neurodevelopmental risk, yet the role of fathers' sensitive caregiving in this process remains understudied. Objective To test whether observed paternal sensitivity predicts cognitive and behavioural outcomes in PT children and moderates prematurity‐related risk.

Endemic but not eroded: Genomic distinctiveness and conservation genomics of the British swallowtail butterfly (Papilio machaon britannicus)

Insect Conservation and Diversity, Volume 19, Issue 5, Page 1260-1274, September 2026.
Through whole‐genome sequencing of P. machaon populations across Europe, we demonstrate that P. m. britannicus forms a genetically distinct and isolated lineage. Demographic modelling revealed weak historical gene flow from the continent. Although P. m.
