Animating ultra-complex voxel scenes through shell deformation

open access: yes, 2010
Voxel representations have many advantages, such as ordered traversal during rendering and trivial very decent LOD through MIPmap. Special effect companies such Digital Domain or Rhythm&Hues now ex- tensively use voxels engines, for semi-transparent objects such as clouds, avalanches, tornado or explosions, but also for complex solid objects.

Textbook of Oyster Biology and Culture in India [PDF]

open access: yes, 2007
Oysters are bivalve molluscs occurring worldwide in temperate, subtropical and tropical seas. Generally they inhabit the coastal waters. Certain species of oysters also occur in lagoons, estuaries and backwaters.

New Onset of Fibromyalgia After Exposure to a Combat Environment: A Longitudinal Cohort Study

open access: yesArthritis Care &Research, EarlyView.
Objective Traumatic life events are hypothesized to be triggers for the onset of fibromyalgia. Posttraumatic stress disorder (PTSD) is a common comorbidity of fibromyalgia. However, limited prospective data are available on the development of fibromyalgia after exposure to high‐magnitude stress.

Can Seed Hardness Be an Ecological Filter in Seed Dispersal by Rodents?

open access: yesDiversity
Seed hardness has been acknowledged as one of the most significant physical traits influencing seed consumption and caching by animals. From an evolutionary perspective, a hard seed shell should potentially be regarded as a dispersal and predator escape ...

Chapter II-2 - Edward S. Morse grows up [PDF]

open access: yes, 1983
In which teenage Edward S. Morse of Salem, Massachusetts, begins a life-long love affair with shells, leaves home for Boston, studies with Louis Agassiz at the Museum of Comparative Zoology in Cambridge, and becomes the world's leading authority on ...

Bistable Mechanisms 3D Printing for Mechanically Programmable Vibration Control

open access: yesAdvanced Engineering Materials, EarlyView.
This work introduces a 3D‐printed bistable mechanism integrated into tuned mass dampers (TMDs) for mechanically adaptive passive vibration suppression. Through optimized geometry, the bistable design provides adaptable vibration reduction across a broad range of scenarios, achieving effective vibration mitigation without complex controls or external ...

Geometry of wave propagation on active deformable surfaces [PDF]

open access: yes, 2018
Fundamental biological and biomimetic processes, from tissue morphogenesis to soft robotics, rely on the propagation of chemical and mechanical surface waves to signal and coordinate active force generation. The complex interplay between surface geometry

Enabling Digital Continuity in Virtual Manufacturing for Eco‐Efficiency Assessment of Lightweight Structures by Means of a Domain‐Specific Structural Mechanics Language: Requirements, Idea and Proof of Concept

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents a solver‐agnostic domain‐specific language (DSL) for computational structural mechanics that strengthens interoperability in virtual product development. Using a hierarchical data model, the DSL enables seamless exchange between diverse simulation tools and numerical methods.

Ocean acidification can interact with ontogeny to determine the trace element composition of bivalve shell

open access: yesLimnology and Oceanography Letters, 2018
We sought to determine how pCO2 will affect the incorporation of trace elements into bivalve shell. This was to validate that under high pCO2 conditions reconstruction of animal movements is still viable; and to investigate potential trace element ...
