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.

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 ...

Spin-polarization after scattering
Physics Open, 2023 This paper deals with the spin-polarization change of an electron beam after elastic scattering with a neutral atom. The first part of the paper is devoted to summarizing the Kessler theory of the elastic scattering of spin-polarized electron beams ...

Journal of High Energy Physics, 2020 We introduce a convolution on a 2-sphere and use it to show that the linearised Becchi-Rouet-Stora-Tyutin transformations and gauge fixing conditions of Einstein-Hilbert gravity coupled to a two-form and a scalar field, follow from the product of two ...

Biological Microbial Interactions from Cooccurrence Networks in a High Mountain Lacustrine District
mSphere, 2022 A fundamental question in biology is why some species tend to occur together in the same locations, while others are never observed coexisting. This question becomes particularly relevant for microorganisms thriving in the highly diluted waters of high ...

Memory effects in Kundt wave spacetimes
Physics Letters B, 2020 Memory effects in the exact Kundt wave spacetimes are shown to arise in the behaviour of geodesics in such spacetimes. The types of Kundt spacetimes we consider here are direct products of the form H2×M(1,1) and S2×M(1,1).

Optical gain in NV-colour centres for highly-sensitive magnetometry: a theoretical study [PDF]
Journal of Physics D: Applied Physics, 2017 Optical gain in an amplifier based on NV- colour centres (CC) in diamond is proposed as a new method for optical magnetic field detection. An analytical expression for magnetic field sensitivity with this method is deduced. The sensitivity is highest at the pump intensities about 100 times above the saturation intensity of NV- CC and can reach values ...

Perturbations of spiky strings in AdS3
Journal of High Energy Physics, 2018 Perturbations of a class of semiclassical spiky strings in three dimensional Anti-de Sitter (AdS) spacetime, are investigated using the well-known Jacobi equations for small, normal deformations of an embedded timelike surface.

Predicting reading ability from brain anatomy and function: From areas to connections
NeuroImage, 2020 Reading is a complex task involving different brain areas. As a crystallized ability, reading is also known to have effects on brain structure and function development.

Emergence of high-energy dynamics from cascade-baryon detections at the LHC
European Physical Journal C: Particles and Fields, 2023 We propose the inclusive detection at the LHC of a cascade $$\Xi ^-/\bar{\Xi }^+$$ Ξ - / Ξ ¯ + baryon in association with a jet, as a novel probe channel for the QCD dynamics at high energies.
