Patience Stones: Material Encounters for Slow Currents of Pedagogy

International Journal of Art &Design Education, EarlyView.
Abstract This article moves across sites in Canada and Japan with the practice of making Patience Stones (Sang‐e Saboor), a biodegradable, dough‐based artistic and pedagogical object that invites artist–teachers and artist–learners into with‐nessing and slow becoming.

Climate‐driven niche filtering limits post‐dispersal establishment and genomic introgression in a riverine shrub

Journal of Integrative Plant Biology, EarlyView.
Integrated biogeographic analysis and macroecological insights reveal that habitat differences drive genetic differentiation Debregeasia orientalis C. J. Chen, a dominant riparian shrub distributed across multiple biodiversity hotspots, and different lineages vary greatly in adaptability to future climate.

CryoFluorSEM – A new approach for fluorescence and EM imaging of cryofractured plant samples

Journal of Microscopy, EarlyView.
Abstract Cryo‐scanning electron microscopy (CryoSEM) permits the preparation and detailed imaging of bulky samples while keeping them in a hydrated state. For plant biology, cryofractures give information on cell ultrastructure and tissue organisation within a much larger context that is the whole organ or organism.

Subversion of plant endomembrane trafficking by a Plasmodiophora brassicae effector PbALE that recruits membrane components at the host–pathogen interface to aid in colonization

New Phytologist, EarlyView.
Schematics of ΔSPPbALE‐induced disruption of plant endomembrane trafficking impairs both preinvasive and postinvasive immunity against filamentous fungi and facilitates intracellular colonization by Plasmodiophora brassicae. Summary Plasmodiophora brassicae, an intracellular biotrophic protist that causes clubroot in crucifers, extensively alters the ...

Effects of Some Properties of Drive Tires Used in Horticultural Tractors on Tractive Performance

Journal of Agricultural Sciences, 2017
Many studies on tractive performance of tractor tires have been carried out to solve soil-wheel interaction problems in the last decades. The purpose of this study is to experimentally determine effects on tractive performance of radial and bias-ply ...

Trait‐based plant ecology: some history and some future

New Phytologist, EarlyView.
Schematic of plant species range boundaries, some mechanisms that might set them, and some traits that might explain them. Summary Since around the year 2000, trait‐based ecology has become self‐aware as a strand of research within ecology. How did this happen? What is trait‐based ecology now? And where might it go in future?

Dynamic Simulation Tool Development for Planetary Rovers

International Journal of Advanced Robotic Systems, 2008
A dynamic computer simulator was developed to study planetary rover mobility. The simulator was validated for step-obstacle negotiation by comparing simulation results with a quasi-static analysis of a rockerbogie suspension.

Characterizing Wheel-Soil Interaction Loads Using Meshfree Finite Element Methods: A Sensitivity Analysis for Design Trade Studies

, 2013
A wheel experiencing sinkage and slippage events poses a high risk to planetary rover missions as evidenced by the mobility challenges endured by the Mars Exploration Rover (MER) project. Current wheel design practice utilizes loads derived from a series

What's Wrong With Self‐Censorship?

Philosophy &Public Affairs, EarlyView.
ABSTRACT In recent years, discourse on freedom of speech has shifted away from exclusive focus on the state and towards societal threats to speech. Amidst this change, the notion of “self‐censorship” has gained increased prominence. Not only has self‐censorship emerged as a common reference point, several recent studies identify it as embodying a ...
