A New 3D Colon on a Chip to Decipher the Influence of Mechanical Forces on the Physiological Cellular Ecosystem

open access: yesAdvanced Healthcare Materials, EarlyView.
To dissect how mechanical forces influence intestinal physiology, we developed a stretchable 3D colon‐on‐chip that integrates tunable topography, stiffness and peristalsis‐like motion within a physiologically relevant microenvironment. We showed that stretching is a dominant factor governing epithelial behavior, markedly enhancing proliferation and ...

Redistribution spurs growth by using a portfolio effect on human capital [PDF]

open access: yes, 2012
We demonstrate by mathematical analysis and systematic computer simulations that redistribution can lead to sustainable growth in a society. The human capital dynamics of each agent is described by a stochastic multiplicative process which, in the long ...

Impact of PVDF Homo and Copolymer on Thiophosphate Solid Electrolyte Characteristics and Comprehensive Bulk‐To‐Surface Characterization

open access: yesAdvanced Materials Interfaces, EarlyView.
This study examines how a PVDF‐like binder affects the argyrodite Li6PS5Cl electrolyte properties. Using an approach that combines bulk and surface characterization with electrochemistry, we found a chemical interaction between Li6PS5Cl and PVDF, resulting in partial chlorine substitution by fluorine and slightly reduced ionic conductivity.

Bidimensional Extensions of Cobalancing and Lucas-Cobalancing Numbers

open access: yesAnnales Mathematicae Silesianae
A new bidimensional version of cobalancing numbers and Lucas-balancing numbers are introduced. Some properties and identities satisfied by these new bidimensional sequences are studied.

Environmental Law and the Supreme Court: Three Years Later [PDF]

open access: yes, 2002
In my Garrison Lecture three years ago, I surveyed the environmental law decisions of the Supreme Court between 1970 and 1999. I commented on which Justices had been more or less influential in shaping the Court\u27s decisions and, even more ...

Investigation of the use of navigation tools in web-based learning: A data mining approach [PDF]

open access: yes, 2008
Web-based learning is widespread in educational settings. The popularity of Web-based learning is in great measure because of its flexibility. Multiple navigation tools provided some of this flexibility.

Extreme‐Temperature Resistant, Flexible, and Sensitive Strain Sensor for Aerospace Parachute Deployment

open access: yesAdvanced Materials Technologies, EarlyView.
In this study, we report a resistive‐type strain sensor fabricated using single‐walled CNTs, are used layer using the pray technique to deposit as conductive, and UV‐resin was spin‐coated as a protection layer. The sensor functioned in harsh temperature variation conditions from −50°C to 125°C without deterioration.
