Adaptable Tile‐Based Pneumatic Origami through Structurally Coupled Localized Actuation

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents tile‐based pneumatic origami structures with rigid tiles and flexible fabric creases, achieving adaptable properties including morphing shape, selective multistability, and tunable stiffness. Independently pressurized folding bladders at each crease enable structurally coupled localized actuation of origami structures.

Anisotropic rupture of polymer strips driven by Rayleigh instability [PDF]

open access: yesThe Journal of Chemical Physics, 2006
We demonstrate that the separated polymer strips of micro- and sub-micro-length-scales rupture anisotropically along the strip direction, resulting in the formation of distinctly observable, regularly spaced polymer drops. The wavelength of the polymer drops and the surface tension dependence of the rupture behavior are found to be well represented by ...

Amplitude Fine-Structure in the Cepheid P-L Relation I: Amplitude Distribution Across the RR Lyrae Instability Strip Mapped Using the Accessibility Restriction Imposed by the Horizontal Branch

open access: yes, 2010
The largest amplitude light curves for both RR Lyrae (RRL) variables and classical Cepheids with periods less than 10 days and greater than 20 days occur at the blue edge of the respective instability strips.

A New Catalog of 100,000 Variable TESS A-F Stars Reveals a Correlation between δ Scuti Pulsator Fraction and Stellar Rotation

open access: yesThe Astrophysical Journal
δ Scuti variables are found at the intersection of the classical instability strip and the main sequence on the Hertzsprung–Russell diagram. With space-based photometry providing millions of light curves of A-F type stars, we can now probe the occurrence

Analysis of Edge Drop on Strip Due to Bending and Elastic Deformation of Back up Rolls in a Four-High Cold Mill

open access: yesMetals
The superficial quality of the strip is a very important issue in steel production. Considering the dimensions, the thickness is one of the most important variables in the production of a strip.

The period distribution of Cepheids: a test of stellar evolution

open access: yesEPJ Web of Conferences, 2015
The period distributions of classical Cepheids in the Small and Large Magellanic Cloud are quite different. Using the TRILEGAL population synthesis code and a theoretical instability strip the ultimate aim is to understand these differences ...

SEARCH OF VARIABILITY OF THE COMPANION OF THE CLASSICAL CEPHEID EV SCT

open access: yesOdessa Astronomical Publications, 2017
Spectroscopic observations of EV Sct obtained on 4m telescope at KPNO showed that the secondary component is probably situated within the instability strip (Kovtyukh & Andrievsky, 1999). Some observers (Pel, 1976; Mermilliod, 1987) have noted a signicant

A Robust Dual‐mode Self‐Monitoring Battery Thermal Management System via Bilayer Structural Design

open access: yesAdvanced Functional Materials, EarlyView.
An adaptive dual‐mode material capable of both evaporative cooling and photothermal preheating is developed. It achieves a cooling efficiency of 53.9%, surpassing existing evaporative cooling counterparts, and a self‐monitoring capability, making it ideal for electric vehicles, portable electronics, and grid‐scale energy storage.

Incisuroplastia troclear e estabilização articular após transecção do ligamento cruzado cranial: Estudo clínico e radiográfico em cães Intercondylar notchplasty and fascial strip repair following transection of the cranial cruciate ligament: Clinical and radiographic aspects in the dog

open access: yesCiência Rural, 2007
Avaliaram-se as alterações clínicas e radiográficas em nove cães adultos, após a transecção do ligamento cruzado cranial (LCCr) seguida da substituição ligamentar por retalho de fáscia lata, associada ou não à incisuroplastia troclear (ITR).
