Multi-PON access network using a coarse AWG for smooth migration from TDM to WDM PON
(2007)An interoperable access network architecture based on a coarse array waveguide grating (AWG) is described, displaying dynamic wavelength assignment to manage the network load across multiple PONs. The multi-PON architecture ... -
Multi-PON access/metro network using a coarse-WDM AWG router
(ACM Press, 2006)A novel access/metro network architecture based on a coarse wavelength division multiplexing array waveguide grating router, supporting multiple passive optical networks (PONs) in the downstream and switching up to 32 ... -
Multi-scale Design Of An Actuator With Thermal-mechanical Energy Conversion And Coupling
(2011)Design of a multi-scale actuator which employs Casimir effect at nano/micro scale in order to provide actuation at meso/macro scale is addressed in this paper. Application of quantum effects at nano scale is beneficial at ... -
Multi-scale Non-equilibrium Molecular Dynamics Formulation For Casimir Energy
(2011)Formulation of the Casimir effect using multi-scale nonequilibrium molecular dynamics (MS-NEMD) is addressed in this paper. Except in the case of parallel plates, simulation of the Casimir effect is a challenging task. ... -
A multi-stable memristor and its application in a neural network
(2020-06-08)Nowadays, there is a lot of study on memristorbased systems with multistability. However, there is no study on memristor with multistability. This brief constructs a mathematical memristor model with multistability. The ... -
A multi-stakeholder approach to the co-production of the research agenda for medicines optimisation
(2021-01-13)BACKGROUND: Up to 50% of medicines are not used as intended, resulting in poor health and economic outcomes. Medicines optimisation is 'a person-centred approach to safe and effective medicines use, to ensure people obtain ... -
Multi-task learning and transfer: The effect of algorithm representation
(ICML, 2005)Exploring multiple classes of learning algorithms for those algorithms which perform best in multiple tasks is a complex problem of multiple-criteria optimisation. We use a genetic algorithm to locate sets of models which ... -
Multi-unionism and the representation of sectional interests in British workplaces
(2008)Britain has been regarded as traditionally having had a ‘problem’ in its industrial relations by virtue of the presence of sectionalism and multi-unionism. This article suggests that this analysis of sectionalism and ... -
A Multi-Value 3D Crossbar Array Nonvolatile Memory Based on Pure Memristors
(2022-05-06)How to improve the storage density and solve the sneak path current problem has become the key to the design of nonvolatile memristive memory. In this paper, a high storage density and high reading/writing speed 3D crossbar ... -
Multi-walled carbon nanotube increases the excitability of hippocampal CA1 neurons through inhibition of potassium channels in rat’s brain slices
(2013-02-27)This study was to investigate the neurotoxicity of multi-walled carbon nanotube (MWCNT) by measuring neuronal excitability in rat hippocampal neurons and exploring the underlying mechanism. Whole cell patch-clamp technique ... -
Multi-walled carbon nanotube inhibits CA1 glutamatergic synaptic transmission in rat's hippocampal slices
(2014-09-17)The purpose of the study was to investigate the neurotoxic effect of multi-walled carbon nanotubes (MWCNTs) on the properties of glutamatergic synaptic transmission in rat's hippocampal slices using whole-cell patch clamp ... -
A Multi-Wave length Survey of the ISM in NGC 628
(Astronomical Society of the Pacific, 1999)Is atomic hydrogen a precursor to or byproduct of the star formation process? Recent evidence suggests that a large percentage of the atomic hydrogen in spiral galaxies could be due to photodissociation of molecular gas ... -
A multi-wavelength access network featuring WiMAX transmission over GPON links
(Institute of Electrical and Electronics Engineers (IEEE), 2010)An IEEE802.16e compliant PON architecture with wavelength band overlay has been demonstrated. Transparent transmission of mobile-WiMAX RF channels over multi-wavelength GPON links, based on FDM, has demonstrated at remote ... -
Multi-wavelength properties of radio and machine-learning identified counterparts to submillimeter sources in S2COSMOS
(2019-11-20)We identify multi-wavelength counterparts to 1,147 submillimeter sources from the S2COSMOS SCUBA-2 survey of the COSMOS field by employing a recently developed radio$+$machine-learning method trained on a large sample of ... -
