The Delicate Bistability of CaMKII [PDF]
Biophysical Journal, 2013 Calcium/calmodulin-dependent protein kinase II (CaMKII) is a synaptic, autophosphorylating kinase that is essential for learning and memory. Previous models have suggested that CaMKII functions as a bistable switch that could be the molecular correlate of long-term memory, but experiments have failed to validate these predictions. These models involved

Advanced Science, EarlyView.Five‐coordinate, square‐pyramidal Fe(II) complexes adopting polar, non‐centrosymmetric crystal structures exhibit exceptionally large easy‐axis magnetic anisotropy. Ligand‐driven distortions critically control the anisotropy, and the dielectric, Polarization vs Elecric field and piezo response studies confirm intrinsic polarization, positioning these ...

Photonic‐Enabled Energy‐Efficient Transparent Neuromorphic Computing Devices: A Review
Advanced Science, EarlyView.Transparent photonic neuromorphic computing devices merge optics and brain‐inspired computing to overcome von Neumann bottlenecks with ultrafast, low‐energy processing. By exploiting transparent oxides, 2D materials, phase‐change materials, and hybrid heterostructures, these platforms enable photonic synapses, memory, and logic for see‐through edge ...

A chemically fueled non-enzymatic bistable network
Nature Communications, 2019 Although bistability is common in biology, it is very difficult to design de novo into synthetic systems. Here, the authors present an experimental and theoretical analysis of a chemical network that displays bistable behavior under certain far-from ...

Programmable Elastic Wave Control Via Mechanical‐Acoustic Interaction in Bistable Metamaterials
Advanced Science, EarlyView.A mechanically programmable metamaterial based on mechanical‐acoustic interaction enables reconfigurable elastic wave control through bistable state switching. Spatial encoding of peak and valley states tunes band structures and transmission, achieving low‐frequency vibration suppression, waveguiding, and energy localization.

Bistability and boundary crisis in a semiconductor laser with phase-conjugate feedback
, 2002 We present a detailed study of a route to chaos via quasiperiodicity on a torus in a semiconductor laser with phase-conjugate feedback. Highlighting the use of new tools that go far beyond mere simulation, we compute bifurcation diagrams and unstable ...

π-System Bistability Determines the Circularly Polarized Luminescence in Helicene para-Phenylenes
We resolve the origin of the anomalous circularly polarized luminescence (CPL) observed in helicene para-phenylenes (HPPs), a new class of chiral macrocyclic nanocarbons reported recently. We show by synthesis of HPPs that embed [5]helicene unit that the
