Bistability in autoimmune diseases
Autoimmunity, 2011 Autoimmune diseases damage host tissue, which, in turn, may trigger a stronger immune response. Systems characterized by such positive feedback loops can display co-existing stable steady states. In a mathematical model of autoimmune disease, one steady state may correspond to the healthy state and another to an autoimmune steady state characterized by

Tunable Low-Threshold Optical Bistability in Optical Tamm Plasmon Superlattices
, 2023 We propose a scheme to obtain tunable low-threshold optical bistability of reflected beams in optical Tamm plasmon superlattices (TPS). The low-threshold optical bistability is triggered due to the strong third-order non-linearity of graphene and the ...

Design‐for‐Benchmarking in Soft Robotics: Navigating Component‐System Dichotomy
Advanced Intelligent Systems, EarlyView.Soft robotics faces a profound evaluation challenge: the Component‐System Dichotomy, where isolated component tests fail to predict integrated performance. This article presents a systematic survey of critical reporting gaps across actuation, sensing, and control.

Controlling the optical bistability via interacting dark-state resonances
, 2010 We analyze the behavior of optical bistability in a four-level mercury atomic system driven by a cavity and two external coherent fields by means of a unidirectional ring cavity. We find that without interacting dark resonances and for large intensity of

Self-heating, bistability, and thermal switching in organic semiconductors [PDF]
, 2012 We demonstrate electric bistability induced by the positive feedback of self-heating onto the thermally activated conductivity in a two-terminal device based on the organic semiconductor C60.

Toward Chromoselective Transformations in Biological Systems: Perspectives and Challenges
Angewandte Chemie International Edition, EarlyView.Controlling biological systems with small‐molecule chromophores has evolved into a powerful strategy and is applied from chemical biology to medicine. However, the complexity of in vivo systems cannot be matched by a single wavelength of light. Developing methods to combine and individually control multiple chromophores is crucial.

COPS OR ROBBERS — A BISTABLE SOCIETY [PDF]
International Journal of Modern Physics C, 2008 The norm game described by Axelrod in 1985 was recently treated with the master equation formalism. Here we discuss the equations, where (i) those who break the norm cannot punish and those who punish cannot break the norm, (ii) the tendency to punish is suppressed if the majority breaks the norm. The second mechanism is new.

A Reversible 900 nm Near‐Infrared Photoswitch for Invisibly Writable 2D and 3D Displays
Angewandte Chemie International Edition, EarlyView.The peri‐benzo[a]fluoranthenethioindigo (PBFT) photoswitch enables direct excitation with near‐infrared light up to 900 nm wavelengths. It delivers a high‐performance property profile including high‐contrast color changes between bright green and deep blue.
