Origami‐Inspired Structural Design for Aquatic‐Terrestrial Amphibious Robots

open access: yesAdvanced Robotics Research, EarlyView.
This work presents a lightweight amphibious origami robot actuated by a single shape memory alloy wire. A rigid foldable origami structure with displacement amplification enables efficient terrestrial crawling and aquatic swimming. The addition of fan‐shaped units allows controllable turning in both environments.

Women and Deliberative Water Management in Brazil [PDF]

open access: yes, 2009
In this paper we consider some gender aspects of the evolution of water management in Brazil. In our work on women and water, we have been inspired by ecofeminist philosophy and the concept of 'feministThis research was supported by the Social Sciences ...

Sleep Alters the Velocity of Physiological Brain Pulsations in Humans

open access: yesAdvanced Science, EarlyView.
Sleep alters I/CSF oscillatory flow, driven by increased respiratory (29%) and vasomotor pulsation (21%) velocities, while cardiovascular pulsations decreased by (22%). Velocity is quantified using optical flow analysis of MREG data. Spectral power increases alongside these pulsations (spatial correlation, r = 0.35 and r = 0.39, respectively ...

The Constitution of Social Practices [PDF]

open access: yes, 2017
Practices – specific, recurrent types of human action and activity – are perhaps the most fundamental "building blocks" of social reality. This book argues that the detailed empirical study of practices is essential to effective social-scientific ...

Nurr1 Orchestrates Claustrum Development and Functionality

open access: yesAdvanced Science, EarlyView.
Nurr1 (Nr4a2) is the master transcription factor to control claustrum morphogenesis and cell fate decision postmitotically by inhibiting intracellular G‐protein signaling. Nurr1 deficiency alters the transcriptomic profiles of subcortical claustral neurons into neocortical insular neurons, resulting in defected claustrum development, impaired axonal ...

Épistémologie et pédagogie chez Gaston Bachelard et Karl Popper

open access: yesRecherches en Éducation, 2017
Although they have many things in common, Bachelard’s epistemology and Popper’s epistemology show distinct conceptions of science and scientific culture, which lead to different and sometimes opposite didactic implications.

Protein Language Model‐Guided Engineering of a 2,3‐Butanediol Dehydrogenase for the Enantioselective Synthesis of Cyclic α‐Hydroxy Ketones

open access: yesAdvanced Science, EarlyView.
A (2R,3R)‐butanediol dehydrogenase from Bacillus subtilis (BsBDH) is engineered for the enantioselective synthesis of 2‐hydroxycyclohexanone. A PASS computational design strategy is proposed to enhance the thermostability of BsBDH. Moreover, ESM‐1v combined with ISM is utilized for enhancing and inverting its stereoselectivity.

Robotic Materials With Bioinspired Microstructures for High Sensitivity and Fast Actuation

open access: yesAdvanced Science, EarlyView.
In the review paper, design rationale and approaches for bioinspired sensors and actuators in robotics applications are presented. These bioinspired microstructure strategies implemented in both can improve the performance in several ways. Also, recent ideas and innovations that embed robotic materials with logic and computation with it are part of the

Phenomenology and educational research [PDF]

open access: yes, 2015
Amongst novice researchers, there is considerable uncertainty about how to use phenomenology as a methodological framework. The problem seems to reside in the fact that phenomenology is a philosophy, a foundation for qualitative research, as well as a ...
