Nestling begging increases predation risk, regardless of spectral characteristics or avian mobbing
Models of parent--offspring conflict and nestling begging honesty often assume that signaling is associated with increased predation risk. However, little evidence exists that begging actuallyExpand

Accuracy and repeatability of a pressure measurement system in the patellofemoral joint.
The objective of this study was to assess how accurately and repeatably the Iscan system measures force and pressure in the natural patellofemoral joint. These measurements must be made to testExpand

Sound Finder: a new software approach for localizing animals recorded with a microphone array
TLDR
We help to relieve the software constraint by developing an acoustic localization program called “Sound Finder”, which is easy to use, freely available and accurate for a variety of animals and recording conditions. Expand

Vocal signals predict attack during aggressive interactions in black-capped chickadees
Animals use a variety of aggressive signals to mediate territorial interactions. Often these signals can be sufficient to ward off potential rivals, thus minimizing the chance of injury due toExpand

Individual and combined effects of OA-related subchondral bone alterations on proximal tibial surface stiffness: a parametric finite element modeling study.
The role of subchondral bone in OA pathogenesis is unclear. While some OA-related changes to morphology and material properties in different bone regions have been described, the effect of theseExpand

Predicting subchondral bone stiffness using a depth-specific CT topographic mapping technique in normal and osteoarthritic proximal tibiae.
BACKGROUND Subchondral bone stiffness is thought to be involved in osteoarthritis pathogenesis. Our objective was to determine if a CT imaging technique, which measures density in relation to depthExpand

Repeatability of a novel technique for in vivo measurement of three‐dimensional patellar tracking using magnetic resonance imaging
TLDR
To determine the repeatability of a novel noninvasive MRI‐based technique for measuring patellofemoral kinematics in vivo. Expand

A non-invasive, 3D, dynamic MRI method for measuring muscle moment arms in vivo: demonstration in the human ankle joint and Achilles tendon.
TLDR
We demonstrate a simple MRI method for measuring muscle moment arms dynamically in 3D from a single range-of-motion cycle without the need to control rotation rate or gate the scanning. Expand

Animal communication: Ground squirrel uses ultrasonic alarms
Apart from echolocation and the pursuit of prey by bats, the function of ultrasound in animal communication is poorly understood. This is mainly because of the broad range of responses that it canExpand

The measurement of joint mechanics and their role in osteoarthritis genesis and progression.
Justifying and improving mechanically based approaches to the treatment and prevention of osteoarthritis (OA) requires a critical understanding of the methods used to study joint mechanics and theExpand
