(Society of Photo-optical Instrumentation Engineers (SPIE), 2003-08-27)The automated identification and quantification of illicit materials using Raman spectroscopy is of significant importance for law enforcement agencies. This paper explores the use of Machine Learning (ML) methods in ... -
Magnetic field-induced asymmetric mechanical metamaterials
(Elsevier, 2023)We propose a magnetic field-induced asymmetric mechanical metamaterial. The tunable metamaterial integrates hard-Magnetic Active Elastomers (hMAEs) into the microstructural design combining snap-through, bi-stability, and ... -
Magneto-deformation and transverse elastic waves in hard-magnetic soft laminates
(Elsevier, 2022-04-28)We study the magneto-mechanical behavior of periodic laminates made of hard-magnetic active elastomers (HMAEs). We formulate the amended free-energy function for HMAEs, and derive an explicit expression for the induced ... -
Magnetoactive asymmetric mechanical metamaterial for tunable elastic cloaking
(Elsevier, 2024-01-08)We propose a magnetic field-induced asymmetric mechanical metamaterial for tunable transformation-based elastic cloaking. The metamaterial is designed by integrating hard-Magnetic Active Elastomers (hMAEs) and combining ... -
Manipulating cocrystal size and morphology using a combination of temperature cycling and additives
(American Chemical Society, 2020-11-20)A cooling crystallization of benzoic acid and isonicotinamide in ethanol yields the 1:1 cocrystal with an extreme needle-like morphology with an initial mean aspect ratio of ∼10 and a size of ∼64 μm. We demonstrate that ... -
Manipulation of intestinal epithelial cell function by the cell contact-dependent type III secretion systems of Vibrio parahaemolyticus
(Frontiers Media, 2014-01-10)Vibrio parahaemolyticus elicits gastroenteritis by deploying Type III Secretion Systems (TTSS) to deliver effector proteins into epithelial cells of the human intestinal tract. The bacteria must adhere to the human cells ... -
Mapping the terrain for the Lean Supply Chain 4.0
(Emerald, 2023-10-03)This study aims to carry out a systematic literature review (SLR) on the integration of Lean, Industry 4.0 and the supply chain or the Lean Supply Chain (LSC) 4.0. The research analyses the current research on the LSC 4.0 ... -
A mathematical model for the release of peptide-binding drugs from affinity hydrogels
(Palgrave, 2015-01-09)A mathematical model for the release of peptide-binding drugs from affinity hydrogels is analyzed in detail. The model is not specific to any particular peptide/drug/gel system, and can describe drug release from a large ... -
A Maximal Eigenvalue Method for Detecting Process Representative Genes by Integrating Data from Multiple Sources
(2008)An important problem in computational biology is the identification of candidate genes which can be considered as representative of the different cellular processes taking place in the cell as it evolves through time. ... -
Measuring knife stab penetration into skin simulant using a novel biaxial tension device
(Elsevier, 2008)This paper describes the development and use of a biaxial measurement device to analyse the mechanics of knife stabbings. In medicolegal situations it is typical to describe the consequences of a stabbing incident in ... -
Measuring the linear and nonlinear elastic properties of brain tissue with shear waves and inverse analysis
(Springer, 2015-02-20)We use supersonic shear wave imaging (SSI) technique to measure not only the linear but also the nonlinear elastic properties of brain matter. Here, we tested six porcine brains ex vivo and measured the velocities of the ... -
Measuring the micro-polarity and hydrogen-bond donor/acceptor ability of thermoresponsive N-isopropylacrylamide/N-tert-butylacrylamide copolymer films using solvatochromic indicators

Mechanical characterization of brain tissue in compression at dynamic strain rates
(Elsevier, 2012-03-02)Traumatic brain injury (TBI) occurs when local mechanical load exceeds certain tolerance levels for brain tissue. Extensive research has been done previously for brain matter experiencing compression at quasistatic loading; ... -
Mechanical characterization of brain tissue in simple shear at dynamic strain rates
(Elsevier, 2013-12)During severe impact conditions, brain tissue experiences a rapid and complex deformation, which can be seen as a mixture of compression, tension and shear. Diffuse axonal injury (DAI) occurs in animals and humans when ... -
Mechanical characterization of brain tissue in tension at dynamic strain rates
(Elsevier, 2012-09-10)Mechanical characterization of brain tissue at high loading velocities is crucial for modeling Traumatic Brain Injury (TBI). During severe impact conditions, brain tissue experiences compression, tension and shear. Limited ... -
Mechanical instability tuning of a magnetorheological elastomer composite laminate
