The Lense--Thirring Effect and Mach's Principle

, 1996
We respond to a recent paper by Rindler on the ``Anti--Machian'' nature of the Lense--Thirring effect. We remark that his conclusion depends crucially on the particular formulation of Mach's principle used.Comment: 13 pages, Latex file, no ...

Increased Elbow Valgus Torque During Pitching Is Not a Risk Factor for Medial Elbow Injuries in Young Baseball Pitchers: A Prospective Cohort Study

Arthroscopy, EarlyView.
Purpose To examine the relationship between elbow valgus torque during pitching and the occurrence of medial elbow injuries in young baseball pitchers prospectively. Methods Between 2019 and 2023, 361 male pitchers aged 9 to 12 years were enrolled. Pitchers with a history of elbow injury or who had not served as pitchers in baseball games for ≥1 year ...

A Geomorphometric Approach to Estimate the Deterioration of Earthen Archaeological Sites by Rainfall and Diffusion Processes: The Huaca Chornancap (Eighth–14th Century ad), Lambayeque, Peru

Archaeological Prospection, EarlyView.
ABSTRACT Rain‐induced erosion processes can severely damage Earthen archaeological sites. Huaca Chornancap (HCH; eighth–14th century ad) is a platform located in the Lambayeque region (Peru) exposed to seasonal rain due to El Niño Southern Oscillation (ENSO).

Spacetime dynamics of spinning particles - exact electromagnetic analogies

, 2016
We compare the rigorous equations describing the motion of spinning test particles in gravitational and electromagnetic fields, and show that if the Mathisson-Pirani spin condition holds then exact gravito-electromagnetic analogies emerge.

Late summer plateau pika spatial habitat use revealed by high‐resolution wildlife tracking and unmanned aerial vehicle data on the Qinghai‐Tibet Plateau

Grassland Research, EarlyView.
Tiny “ecosystem engineers,” plateau pikas range across 1600 m², about two basketball courts, mixing soil and nutrients that sustain Tibet's fragile grasslands. Custom‐made trackers and drone imagery show dawn‐to‐dusk surface foraging and nested‐scale patch choices, offering fresh guidance for wildlife‐friendly grazing management.

Dynamic Characteristics of Vertically Coupled Structures and the Design of a Decoupled Micro Gyroscope

Sensors, 2008
In a vertical type, vibratory gyroscope, the coupled motion between reference (driving) and sensing vibrations causes the zero-point output, which is the unwanted sensing vibration without angular velocity.
