Whirl Flutter Stability Analysis Using Propeller Transfer Matrices [PDF]

Whirl flutter is an aeroelastic instability that requires accurate prediction during propeller aircraft design. However, current flutter analysis methods in the frequency domain only include simplified propeller transfer functions. This work proposes a new method to represent the propeller using identified transfer matrices between hub displacements ...

Liquid Atmospheric Pressure MALDI (LAP‐MALDI) Mass Spectrometry: A Versatile Tool for the Characterization of Synthetic Polymers

Rapid Communications in Mass Spectrometry, Volume 40, Issue 16, 30 August 2026.
ABSTRACT Rationale Liquid atmospheric pressure matrix‐assisted laser desorption/ionization (LAP‐MALDI) mass spectrometry (MS) has previously been applied to the analysis of biopolymers such as peptides, proteins, and DNA, producing ESI‐like multiply charged analyte ions.

Estimating Wind‐Power Capacity Time Series From Production Data Using a Power Curve Model and Quadratic Optimization

Wind Energy, Volume 29, Issue 8, August 2026.
ABSTRACT Accurate, time‐resolved installed capacity data are crucial for forecasting and analysing wind‐power production. The time series of installed capacity is often only approximately known in regions with rapid wind power development. Public wind power databases may only be updated yearly and installation dates may not be differentiated within ...

ALERA‐V Version 1.0: An Objective Analysis Dataset of the Venus Atmosphere

Geoscience Data Journal, Volume 13, Issue 3, July 2026.
Using observations from the Venus orbiter Akatsuki, we present the first objective analysis dataset of the Venus atmosphere. ALERA‐V, generated with the ALEDAS‐V system using the LETKF, is expected to support studies of atmospheric dynamics and the planning of future satellite missions.

Optimizing Selective RF Pulses for Enhanced Signal Stability in Turbo Spin Echo Using a Differentiable Extended Phase Graph Model

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 214-226, July 2026.
ABSTRACT Purpose To improve slice profile consistency across echo trains in turbo spin echo (TSE) imaging, thereby reducing image blurring and increasing the accuracy of multi echo spin echo T2$$ {T}_2 $$ mapping. Methods Excitation and refocusing RF pulses were optimized for TSE using a differentiable extended phase graph model that incorporates the ...

What No Research Means: The Problematic of Time and Possibilities for Expansiveness in Interpretive Literacy Research

Reading Research Quarterly, Volume 61, Issue 3, July/August/September 2026.
ABSTRACT This article examines what becomes possible for interpretive literacy research when time is treated not as a neutral backdrop but as a central problematic. We argue that research does not merely trace temporal sequences; it actively creates temporalities that shape what becomes sensible, thinkable, and sayable within literacy studies.

Application of Deep Learning and Explainable AI to NIR Auroral Detection in Satellite Time‐Series Images

Space Weather, Volume 24, Issue 7, July 2026.
Abstract In this study, we employ a deep learning approach to detect auroras from near‐infrared (NIR) sequential images captured by the satellite‐based imager, the Enhanced Polar Outflow Probe (e‐POP)/Fast Auroral Imager (FAI). We also apply the Eigen‐Class Activation Map (Eigen‐CAM), an explainable AI technique in a broad sense, as a post‐hoc ...

Sensitivity of Propeller Whirl Flutter With Respect to Blade Parameters [PDF]

AIAA SCITECH 2025 Forum
New methods for propeller whirl flutter prediction emerge, enabling aeroelastic engineers to include more modeling parameters and more sophisticated methods into their analysis. However, the sensitivity of propeller whirl flutter with respect to modeling parameters like airfoil characteristics, blade sweep and stiffness is not clear. This makes it hard

Advancing Ecological Understanding and Sustainable Management of Small Pelagic Fish

Fish and Fisheries, Volume 27, Issue 4, Page 850-864, July 2026.
ABSTRACT Small pelagic fish (SPF) are critical to the trophodynamic structure and function of marine systems and support some of the most valuable and socially important fisheries worldwide. Their “boom and bust” population dynamics, shifts in distribution, and importance as forage resources for other fish stocks place unique challenges to assessing ...
