Programmable Chirality Transfer: Seeding‐Directed Co‐Assembly of Functional Molecules With Amyloid Frameworks

open access: yesSmall, EarlyView.
Seeding‐directed co‐assembly enables efficient chirality transfer from chiral amyloid scaffold to achiral functional molecules. Controlled assembly pathways result in hierarchical hybrid supramolecular structures showing enhanced induced electronic circular dichroism (IECD) and/or vibrational circular dichroism (IVCD).

Visual control of hovering in Anna's hummingbirds

open access: yes, 2017
Relatively little is known about how sensory information is used for controlling flight in birds. A powerful method is to immerse an animal in a dynamic virtual reality environment to examine behavioral responses.

Tactic Behaviors in Asymmetric Pacman Particles

open access: yesSmall, EarlyView.
The swimming behavior of TiO2 Pacman particles exhibits different modes depending on the fuel and illumination conditions. However, the behavior of these intrinsically asymmetric particles is still not well understood, and here we present a first approach to modeling their dynamics. Furthermore, we investigate their fundamental responses to some of the

Facilitating System Change With GOSR: Integrating AI and Human Collaboration

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT Problem solving in complex domains requires approaches that encourage systems thinking, collaboration, and recognize multiple simultaneous solutions. Building from principles of General Systems Theory and existing problem structuring methods, we present a new method for supporting system partners working to address complex problems called GOSR.

Eco‐ductile design of RC columns: Resolving the conflict between embodied carbon and curvature ductility

open access: yesStructural Concrete, EarlyView.
Abstract Reducing embodied carbon emissions in structural design is of critical importance in combating global climate change. However, the increased material usage and heavy confinement reinforcement required to meet high ductility demands in reinforced concrete columns directly conflict with environmental sustainability goals.

Looking for Trouble: Pre‐Intervention Monitoring in Human and AI Driver Training

open access: yesSymbolic Interaction, EarlyView.
We compare two types of situations involving monitoring of car driving: a driving instructor overseeing a trainee driver and a safety driver overseeing the performance of autonomous vehicle (AV) software. Our focus is on instances of monitoring that precede (1) interventions that are aborted before impacting the driving and (2) actual interventions on ...

“Who Is Watching me?”: Recovering the Grammar of Stigma in Interaction

open access: yesSymbolic Interaction, EarlyView.
This article offers a praxeological respecification of stigma. I argue that the term “stigma” is a category term and glossing device, used to gather together and stand in for a diverse range of interactional experiences, including, but not limited to, degradation, discrediting, discrimination, marginalization, and being demeaned.

Supporting Young Foreign Language Learners With Image Generative AI in Digital Multimodal Composing: Benefits and Challenges

open access: yesTESOL Quarterly, EarlyView.
Abstract Integrating generative artificial intelligence (GenAI) into digital multimodal composing (DMC) offers promising avenues for young Foreign Language (FL) learners' learning experiences. Image‐based GenAI tools enable students to generate personalized images from written prompts to help convey meanings, and DMC combines text, images, and sound to
