Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract Shipboard gravity anomaly data provide high‐resolution information for a wide range of Earth and ocean science research as well as ground‐truthing US national geodetic modeling. Motivated by the end of life‐cycle for legacy Bell aerospace marine Gravity Meter system (BGM‐3) gravimeters onboard vessels in the U.S. Academic Research Fleet, a new

Water Resources Research, Volume 62, Issue 5, May 2026.Abstract Information on river velocities enhances understanding flood hazards, evaluating habitat conditions, and predicting the transport of floating materials. In this follow‐up study, we used data from two new sites, one with a more complex morphology and the other with a lower suspended sediment concentration, to provide further evidence that ...

Theoretical three-and four-axis gimbal robot wrists [PDF]
In high-performance flight simulations, a four-axis gimbal system allows all possible rotations with acceptable gimbal angle rates while it avoids the so-callled 'gimbal lock' that occurs when gimbal rotational axes are colinear. In this paper, pertinent

Geoscience Data Journal, Volume 13, Issue 2, April 2026.We present the Weather Rescue at Sea dataset, generated from a citizen‐science project which transcribed millions of weather observations contained in 19th Century UK Royal Navy ship logbooks. This corrected and quality‐assured dataset will enhance historical reconstructions of the pre‐modern climate by providing more input meteorological data ...

Equilibrium properties of the Skylab CMG rotation law [PDF]
The equilibrium properties of the control moment gyroscopes of the Skylab are discussed. A rotation law is developed to produce gimbal rates which distribute the angular momentum contributions among the control moment gyroscopes to avoid gimbal stop ...

Perceptions of female age, health and attractiveness vary with systematic hair manipulations
International Journal of Cosmetic Science, Volume 48, Issue 2, Page 296-309, April 2026.Two experiments were conducted to study how lay individuals evaluate systematic changes in female head hair. The results showed that participants tended to rate high‐shine hair more favourably than lower‐shine hair. When combining shine with alignment and volume, straight‐aligned hair with high shine and low volume was generally perceived as more ...

Centaur engine gimbal friction characteristics under simulated thrust load [PDF]
An investigation was performed to determine the friction characteristics of the engine gimbal system of the Centaur upper stage rocket. Because the Centaur requires low-gain autopilots in order to meet all stability requirements for some configurations ...

A motion-decomposition approach to address gimbal lock in the 3-cylinder open chain mechanism description of a joint coordinate system at the glenohumeral joint [PDF]
, 2010 In this study, the standard-sequence properties of a joint coordinate system were implemented for the glenohumeral joint by the use of a set of instantaneous geometrical planes.

Advanced Intelligent Systems, Volume 8, Issue 3, March 2026.This review systematically analyzes deformable drones, including extendable, foldable, and tilting configurations, along with nature‐inspired flapping rotorcraft. By classifying deformation principles and structural mechanisms, design trade‐offs, functional capabilities, and future development potential are highlighted.
