On the galloping instability of two-dimensional bodies having elliptical cross sections. [PDF]

, 2010
Galloping, also known as Den Hartog instability, is the large amplitude, low frequency oscillation of a structure in the direction transverse to the mean wind direction.

Meta‐Virtuality: Strategies of Disembeddedness in Virtual Interiorities

Journal of Interior Design, EarlyView., 2022
ABSTRACT To reclaim their seat in the rapidly growing market of virtual space, designers of the built environment can benefit from reevaluating theories that see the virtual as a mere extension/reflection of the physical. By claiming ontological autonomy from external worlds, the virtual is liberated from the hegemonic control of the physical.

The refined inviscid stability condition and cellular instability of viscous shock waves [PDF]

, 2009
Combining work of Serre and Zumbrun, Benzoni-Gavage, Serre, and Zumbrun, and Texier and Zumbrun, we propose as a mechanism for the onset of cellular instability of viscous shock and detonation waves in a finite-cross-section duct the violation of the ...

Leveraging Elastic instabilities for Amplified Performance: spine-inspired high-speed and high-force soft robots

, 2020
Soft machines typically exhibit slow locomotion speed and low manipulation strength because of intrinsic limitations of soft materials. Here, we present a generic design principle that harnesses mechanical instability for a variety of spine-inspired fast

Perceptual bistability in auditory streaming: how much do stimulus features matter? [PDF]

, 2013
The auditory two-tone streaming paradigm has been used extensively to study the mechanisms that underlie the decomposition of the auditory input into coherent sound sequences.

One-dimensional nonlinear stability of pathological detonations [PDF]

, 2000
In this paper we perform high-resolution one-dimensional time-dependent numerical simulations of detonations for which the underlying steady planar waves are of the pathological type.

Morphological Evaluation of the Hip Joint and Pelvic Limb Bones of the Lowland Tapir (Tapirus terrestris Linnaeus, 1758) Using Radiography and Computed Tomography. [PDF]

Anat Histol Embryol
ABSTRACT The study aimed to characterize, through imaging examinations—including radiographs and computed tomography—the hip joint and the bones of the thigh, leg and feet in Lowland tapirs (Tapirus terrestris). Ten pelvic limbs were collected, two from juveniles and the remaining from adults. The femoral head exhibited a rounded morphology with a well‐
