MATRIX ALGEBRAS WITH A CERTAIN COMPRESSION PROPERTY I
(Elsevier, 2021-07-15)An algebra A of n × n complex matrices is said to be projection compressible if P AP is an algebra for all orthogonal projections P ∈ Mn(C). Analogously, A is said to be idempotent compressible if EAE is an algebra for all ... -
Matrix compatible solid phase microextraction coating, a greener approach to sample preparation in vegetable matrices
(Elsevier, 2017-09-01)This work proposes the novel PDMS/DVB/PDMS fiber as a greener strategy for analysis by direct immersion solid phase microextraction (SPME) in vegetables. SPME is an established sample preparation approach that has not yet ... -
Matrix representations of the inverse problem in the graph model for conflict resolution
(Elsevier, 2018-10-01)Given the final individual stability for each decision maker or an equilibrium of interest, a matrix-based method for an inverse analysis is developed in order to calculate all of the possible preferences for each decision ... -
Maximal cell density predictions for compressible polymer foams
(Elsevier, 2012-12-05)Thermodynamic upper bounds for polymer foam cell densities are predicted using compressible selfconsistent field theory. It is found that the incompressible limit always gives the highest, and therefore ultimate, upper ... -
Maximal voluntary isometric contraction tests for normalizing electromyographic data from different regions of supraspinatus and infraspinatus muscles: Identifying reliable combinations
(Elsevier, 2018-08-01)This study aimed to identify optimal sets of maximal voluntary isometric contractions (MVICs) for normalizing EMG data from anterior and posterior regions of the supraspinatus, and superior, middle and inferior regions of ... -
Maximum likelihood estimation of first-passage structural credit risk models correcting for the survivorship bias
(Elsevier, 2019-03)The survivorship bias in credit risk modeling is the bias that results in parameter estimates when the survival of a company is ignored. We study the statistical properties of the maximum likelihood estimator (MLE) accounting ... -
Mean field analysis gives accurate predictions of the behaviour of large networks of sparsely coupled and heterogeneous neurons
(BioMed Central, 2014-07-21)Large networks of integrate-and-fire (IF) model neurons are often used to simulate and study the behaviour of biologically realistic networks. However, to fully study the large network behaviour requires an exploration of ... -
Mean-Expectile Portfolio Selection
(Springer, 2021)We consider a mean-expectile portfolio selection problem in a continuous-time diffusion model. We exploit the close relationship between expectiles and the Omega performance measure to reformulate the problem as the ... -
Mean-field models for heterogeneous networks of two-dimensional integrate and fire neurons
(Frontiers Media, 2017-12-27)We analytically derive mean-field models for all-to-all coupled networks of heterogeneous, adapting, two-dimensional integrate and fire neurons. The class of models we consider includes the Izhikevich, adaptive exponential ... -
Meaningful faces: Self-relevance of semantic context in an initial social encounter improves later face recognition
(Springer, 2021-02)Self-relevant stimuli (i.e. meaningful/important to the observer and related to the self) are typically remembered better than other-relevant stimuli. However, whether a self-relevance memory benefit could be conferred to ... -
Measuring Behaviour Interactions between Product-Line Features
(IEEE, 2015-05)We suggest a method for measuring the degree to which features interact in feature-oriented software development. To this end, we extend the notion of simulation between transition systems to a similarity measure and lift ... -
Measuring effective diffusivity in porous media with a gasket-free, radial arrangement
(Elsevier, 2019-02-01)A simple technique for measuring the effective diffusivity, and ultimately tortuosity, in porous media is presented. The method uses a custom-built apparatus, based on a radial geometry, which eliminates the need for any ... -
Measuring Haptic Experience: Elaborating the HX model with scale development
(IEEE, 2021-07-06)Designers increasingly employ haptic feedback with the aim to improve user experience (UX). Designers and researchers currently use qualitative methods or demos for feedback, but neither approach scales to large studies ... -
Measuring the implementation of a group-based Lifestyle-integrated Functional Exercise (Mi-LiFE) intervention delivered in primary care for older adults aged 75 years or older: a pilot feasibility study protocol
(BioMed Central, 2015-12-01)Background Declines in function and quality of life, and an increased risk of cardiovascular events, falls, and fractures occur with aging and may be amenable to exercise intervention. Primary care is an ideal setting for ... -
Measuring wellbeing performance of carbon emissions using hybrid measure and meta-frontier techniques: Empirical tests for G20 countries and implications for China
(Elsevier, 2019-11-10)A quantitative measure of performance that integrates national-level carbon emission profiles with key parameters of social and economic wellbeing can provide an effective management tool for policy interventions. This ... -
The mechanism of pore segregation in the sintered nano Ag for high temperature power electronics applications
(Elsevier, 2018-10-01)It is widely accepted that nano pores of sintered nanoparticles can coalesce into micro pores during high temperature service. When applying sintered nanoparticles in power electronics, the pore segregation and delamination ... -
Mechanisms of DNA Sensing on Graphene Oxide
(American Chemical Society, 2013-08-20)Adsorption of a fluorophore-labeled DNA probe by graphene oxide (GO) produces a sensor that gives fluorescence enhancement in the presence of its complementary DNA (cDNA). While many important analytical applications have ... -
Mechanistic studies on the effect of membrane lipid acyl chain composition on daptomycin pore formation
(Elsevier, 2018-11-01)Daptomycin is a lipopeptide antibiotic that binds and permeabilizes the cell membranes of Gram-positive bacteria. Membrane permeabilization requires both calcium and phosphatidylglycerol (PG) in the target membrane, and ... -
Mechatronic design, actuator optimization, and control of a long stroke linear nano-positioner
(Elsevier, 2018-04-01)In this paper, mechatronic design, actuator optimization and controls of a long-stroke (20 mm) linear nano-positioner are presented. The mechatronic design is described in terms of the stage's most prominent features ... -
