Jamming by compressing a system of granular crosses
EPJ Web of Conferences, 2017 A disordered stress-free granular packing can be jammed, transformed into a mechanically rigid structure, by increasing the density of particles or by applying shear deformation.

Complexity of cortical wave patterns of the wake mouse cortex
Nature Communications, 2023 The cerebral cortex has ongoing electrical activities with rich and complex patterns in space and time. Here, the authors use optical voltage imaging in mice and computational methods, relating these complexities to different levels of wakefulness.

Pulling an intruder from a granular material: a novel depinning experiment
EPJ Web of Conferences, 2017 Two-dimensional impact experiments by Clark et al. [2] identified the source of inertial drag to be caused by ‘collisions’ with a latent force network, leading to large fluctuations of the force experienced by the impactor.

Gamma Oscillations Facilitate Effective Learning in Excitatory-Inhibitory Balanced Neural Circuits
Neural Plasticity, 2021 Gamma oscillation in neural circuits is believed to associate with effective learning in the brain, while the underlying mechanism is unclear. This paper aims to study how spike-timing-dependent plasticity (STDP), a typical mechanism of learning, with ...

Static Output Feedback Control of Switched Nonlinear Systems With Actuator Faults
IEEE transactions on fuzzy systems, 2020 This paper is focused on the static output feedback (SOF) control problem for a class of switched nonlinear systems with actuator faults. By means of the Takagi–Sugeno fuzzy model, the switched nonlinear plant is described by a family of switched fuzzy ...

Absence Seizure Control by a Brain Computer Interface
Scientific Reports, 2017 The ultimate goal of epileptology is the complete abolishment of epileptic seizures. This might be achieved by a system that predicts seizure onset combined with a system that interferes with the process that leads to the onset of a seizure.
