A Covariant Feynman Path Amplitude Calculation of Neutrino and Muon Oscillations [PDF]

open access: yesarXiv, 2001
Predictions are presented for the oscillation phase in neutrino oscillations following pion decay at rest and in flight, muon decay and nuclear $\beta-$decay at rest as well as for muon oscillations following pion decay at rest and in flight. The neutrino oscillation phases found disagree with the conventionally used value: $\phi_{12} = \Delta m^2 L ...

Low‐Velocity Penetration Impact Behavior of Triply Periodic Minimal Surface Strut‐Based Lattices

open access: yesAdvanced Engineering Materials, EarlyView.
Triply periodic minimal surface (TPMS)‐based lattices are gaining attention for their multifunctional properties in applications as aeronautics and automotive, which involve low‐velocity impact loading. This work evaluates the low‐velocity penetration impact behavior of five distinct TPMS architectures.

Wide area inter-area oscillation control system in a GB electric power system

open access: yesThe Journal of Engineering, 2019
A wide area control system (WACS) for the Great Britain (GB) power system is presented. This WACS is designed to enhance the GB system's small signal stability, i.e.

Decoherence of Quantum Damped Oscillators [PDF]

open access: yesJ. Korean Phys. Soc. 43 (2003) 452-460, 2002
Quantum dissipation is studied within two model oscillators, the Caldirola-Kanai (CK) oscillator as an open system with one degree of freedom and the Bateman-Feshbach-Tikochinsky (BFT) oscillator as a closed system with two degrees of freedom. Though these oscillators describe the same classical damped motion, the CK oscillator retains the quantum ...

Covalently‐Bonded Diaphite Nanoplatelet with Engineered Electronic Properties of Diamond

open access: yesAdvanced Functional Materials, EarlyView.
A novel approach to engineering the electronic properties of diamond is reported on the diaphite nanoplatelet consisting of (11¯${{\bar{1}}}$1) planes of diamond nanoplatelet covalently bonded with graphite (0001) planes. The strong sp3/sp2‐hybridized interfacial covalent bonding induces the electron transfer from diamond to graphite, resulting in a ...

Functionally distinct high and low theta oscillations in the human hippocampus

open access: yesNature Communications, 2018
Based on rodent models, researchers have theorized that the hippocampus supports episodic memory and navigation via the theta oscillation, a ~4–10 Hz rhythm that coordinates brain-wide neural activity.

Direct Ink Writing of Conductive Hydrogels

open access: yesAdvanced Functional Materials, EarlyView.
This review examines the use of direct ink writing (DIW) for fabricating conductive hydrogels with customizable 3D structures. It outlines the rheological requirements for successful DIW, followed by an exploration of the materials and ink formulations used to impart electronic and/or ionic conductivity to hydrogels while maintaining printability ...

Markers of criticality in phase synchronisation

open access: yesFrontiers in Systems Neuroscience, 2014
The concept of the brain as a critical dynamical system is very attractive because systems close to criticality are thought to maximise their dynamic range of information processing and communication.
