Hyperspectral cathodoluminescence imaging of modern and fossil carbonate shells [PDF]
, 2006 Optical cathodoluminescence (CL) is commonly used to identify diagenetically altered carbonate fossils, yet such an interpretation is problematic as present-day carbonate shells may also luminesce.

Jet–cavity coupling and structural response characteristics of hollow shell with truncated cone during vertical high-speed water entry [PDF]
AIP AdvancesThis paper adopts a coupled fluid–structure interaction method based on computational fluid dynamics and the finite element method to investigate the high-speed vertical water entry of hollow truncated cone shells and systematically reveal the regulatory

Implosion of Indirectly Driven Reentrant-Cone Shell Target [PDF]
Physical Review Letters, 2003 We have examined the implosion of an indirectly driven reentrant-cone shell target to clarify the issues attendant on compressing fuel for a fast ignition target. The target design is the hydrodynamic equivalent of a NIF cryoignition target scaled to be driven by Omega. Implosions were imaged with backlit x radiographs and modeled with LASNEX.

Bat eyes have ultraviolet-sensitive cone photoreceptors [PDF]
, 2009 Mammalian retinae have rod photoreceptors for night vision and cone photoreceptors for daylight and colour vision. For colour discrimination, most mammals possess two cone populations with two visual pigments (opsins) that have absorption maxima at short

GLASS: Generator for Large Scale Structure
The Open Journal of Astrophysics, 2023 We present GLASS, the Generator for Large Scale Structure, a new code for the simulation of galaxy surveys for cosmology, which iteratively builds a light cone with matter, galaxies, and weak gravitational lensing signals as a sequence of nested shells ...

Study on acoustic vibration similarity law of complex stiffened cone-cylinder combined shell
Zhongguo Jianchuan Yanjiu, 2022 ObjectiveDue to the difficulty of accurately converting the experimental results of acoustic radiation and vibration from scale models of complex stiffened combined shells into prototypes, the acoustic vibration similarity laws of this type of combined ...

A numerical investigation into the plastic buckling paradox for circular cylindrical shells under axial compression [PDF]
, 2014 It is widely accepted that for many buckling problems of plates and shells in the plastic range the flow theory of plasticity leads to a significant overestimation of the buckling stress while the deformation theory provides much more accurate ...
