In Defense of Imperfection

open access: yesCanadian Journal of Academic Librarianship
The demand for perfect solutions to complex institutional problems creates excessive, ever-changing barriers for racialized peoples working toward transformative justice. The same demand is not made of the methods used to adopt the emerging technologies

Remorphable Architectures: Reprogramming Global Bistability through Locally Bistable Metamaterials

open access: yesAdvanced Materials, EarlyView.
Local bistable reconfiguration in mechanical metamaterials is leveraged in globally bistable architectures to enable in situ reprogrammable transition pathways through state flip of individual building blocks. The local‐to‐global correspondence of instabilities empowers soft robotic systems with on‐demand morphing traits, as well as aerospace ...

Imperfection

open access: yes, 2012
??aspirations to perfection awaken us to our actual imperfection.? It is in the space between these aspirations and our inability to achieve them that Grant reflects upon imperfection. Grant argues that an awareness of imperfection, defined as both suffering and the need for justice, drive us to an unrelenting search for perfection, freedom, and self ...

Multifunctional Fluidic Units for Emergent, Responsive Robotic Behaviors

open access: yesAdvanced Materials, EarlyView.
A multifunctional reconfigurable fluidic unit can be used as sensor, valve and actuator is presented. A unique configuration combines the features of the three components as a Responsive self‐oscillating actuator. The remarkable versatility of the fluidic unit is demonstrated by building different robots with the same fluidic units only by varying ...

Transistor‐Level Activation Functions via Two‐Gate Designs: From Analog Sigmoid and Gaussian Control to Real‐Time Hardware Demonstrations

open access: yesAdvanced Materials, EarlyView.
Screen gate‐based transistors are presented, enabling tunable analog sigmoid and Gaussian activations. The SA‐transistor improves MRI classification accuracy, while the GA‐transistor supports precise Gaussian kernel tuning for forecasting. Both functions are implemented in a single device, offering compact, energy‐efficient analog AI processing ...

Solvent‐Free Thermal Defect Engineering in Molecular Frameworks With Volatile Linkers

open access: yesAdvanced Materials, EarlyView.
Thermal removal of neutral volatile linkers enables precise and solvent‐free generation of metal vacancies in MOFs. This strategy affords redox‐stable, coordinatively unsaturated FeII sites with tunable spin, ligand coordination, and catalytic behavior. The approach offers a general route to design defect‐functional materials through local coordination
