Long-Term Stability of Horseshoe Orbits

open access: yes, 2012
Unlike Trojans, horseshoe coorbitals are not generally considered to be long-term stable (Dermott and Murray, 1981; Murray and Dermott, 1999). As the lifetime of Earth's and Venus's horseshoe coorbitals is expected to be about a Gyr, we investigated the ...

Joint assembly and genetic mapping of the Atlantic horseshoe crab genome reveals ancient whole genome duplication [PDF]

open access: yes, 2013
Horseshoe crabs are marine arthropods with a fossil record extending back approximately 450 million years. They exhibit remarkable morphological stability over their long evolutionary history, retaining a number of ancestral arthropod traits, and are ...

In-vitro study of arterial vessel stiffness on wall shear stress reversal under physiological pulsatile flow conditions

open access: yesMedicine in Novel Technology and Devices
This study investigates the impact of arterial stiffness on wall shear stress (WSS) reversal, a critical factor in vascular health and disease. The cardiovascular system's endothelial cells respond to mechanical stimuli, such as WSS, which influences ...

Association between radiographic equine distal phalanx characteristics and absence, presence and type of horseshoes

open access: yesFrontiers in Veterinary Science
Most horses are used with horseshoes additionally supported by either dorsoabaxial or dorsal clips. The effects of such clips on bone density and shape of the distal phalanx are currently unclear.

Prosomal-width-to-weight relationships in American horseshoe crabs (Limulus polyphemus): examining conversion factors used to estimate landings [PDF]

open access: yes, 2009
Horseshoe crabs (Limulus polyphemus) are valued by many stakeholders, including the commercial fishing industry, biomedical companies, and environmental interest groups.

Embeddings of low-dimensional strange attractors: Topological invariants and degrees of freedom [PDF]

open access: yes, 2007
When a low dimensional chaotic attractor is embedded in a three dimensional space its topological properties are embedding-dependent. We show that there are just three topological properties that depend on the embedding: parity, global torsion, and knot ...

A Laminating Strategy to Manyfold Enhance the Elastic Stretchability of Stretchable Electronics

open access: yesAdvanced Science, EarlyView.
We propose a laminating strategy that laminates a thick‐polymer layer onto the thin‐ribbon metallic structure. Using serpentine structures on soft and hard substrates as representative cases, this approach increases elastic stretchability by 3.5‐fold and 2.3‐fold.

A review of the biology and management of horseshoe crabs, with emphasis on Florida populations [PDF]

open access: yes, 2007
In Florida, some horseshoe crabs are fished for eel bait, but they are fished principally by the marine-life industry, which collects the animals live for resale as aquarium, research, or educational specimens.

Deep Learning Methods for Assessing Time‐Variant Nonlinear Signatures in Clutter Echoes

open access: yesAdvanced Intelligent Systems, EarlyView.
Motion classification from biosonar echoes in clutter presents a fundamental challenge: extracting structured information from stochastic interference. Deep learning successfully discriminates object speed and direction from bat‐inspired signals, achieving 97% accuracy with frequency‐modulated calls but only 48% with constant‐frequency tones.
