A new twist on PIFE: photoisomerisation-related fluorescence enhancement
Evelyn Ploetz, Benjamin Ambrose, Anders Barth +12
PIFE was first used as an acronym for protein-induced fluorescence enhancement, which refers to the increase in fluorescence observed upon the interaction of a fluorophore, such as…
Soft Metamaterials: Adaptation and Intelligence
Colin Scheibner, Michel Fruchart, Vincenzo Vitelli
We provide a perspective on soft metamaterials and biomatter with a special emphasis on future research directions at the interface between material intelligence and adaptation.
ZSCRGAN: A GAN-based Expectation Maximization Model for Zero-Shot Retrieval of Images from Textual Descriptions
Anurag Roy, Vinay Kumar Verma, Kripabandhu Ghosh +1
Most existing algorithms for cross-modal Information Retrieval are based on a supervised train-test setup, where a model learns to align the mode of the query (e.g., text) to the m…
Coupling conditions for globally stable and robust synchrony of chaotic systems
Suman Saha, Arindam Mishra, E. Padmanaban +4
We propose a set of general coupling conditions to select a coupling profile (a set of coupling matrices) from the linear flow matrix (LFM) of dynamical systems for realizing globa…
Coherent libration to coherent rotational dynamics via chimeralike states and clustering in Josephson Junction array
Arindam Mishra, Suman Saha, Chittaranjan Hens +5
An array of excitable Josephson junctions under global mean-field interaction and a common periodic forcing shows emergence of two important classes of coherent dynamics, libration…
Chimeralike states in a network of oscillators under attractive and repulsive global coupling
Arindam Mishra, Chittaranjan Hens, Mridul Bose +2
We observe chimeralike states in an ensemble of oscillators using a type of global coupling consisting of two components: attractive and repulsive mean-field feedback. We identify…
Extreme multistability: Attractor manipulation and robustness
Chittaranjan Hens, Syamal K. Dana, Ulrike Feudel
The coexistence of infinitely many attractors is called extreme multistability in dynamical systems. In coupled systems, this phenomenon is closely related to partial synchrony and…
Bursting dynamics in a population of oscillatory and excitable Josephson junction
Chittaranjan Hens, Pinaki Pal, Syamal K. Dana
We report parabolic bursting in a globally coupled network of mixed population of oscillatory and excitable Josephson junctions. The resistive-capacitive shunted junction (RCSJ) mo…
Generalized counter-rotating oscillators: Mixed synchronization
Sourav K. Bhowmick, Bidesh K. Bera, Dibakar Ghosh
In this paper, we report mixed synchronization between two counter rotating chaotic oscillators. We describe a procedure how to obtain a counter rotating oscillator for generalized…
Transition from amplitude to oscillation death in a network of oscillators
Mauparna Nandan, C. R. Hens, Pinaki Pal +1
We report a transition from a homogeneous steady state (HSS) to inhomogeneous steady states (IHSSs) in a network of globally coupled identical oscillators. We perturb a synchronize…

C. R. Hens, A. Mishra, P. K. Roy +2
We report the existence of a chimera state in an assembly of identical nonlinear oscillators that are globally linked to each other in a simple planar cross-coupled form. The rotat…

We report the existence of diverse routes of transition from amplitude death (AD) to oscillation death (OD) in three different diffusively coupled systems, those are perturbed by a…

Lag synchronization is a basic phenomenon in mismatched coupled systems, delay coupled systems and time-delayed systems. It is characterized by a lag configuration that establishes…
