Neutron Interferometry at the National Institute of Standards and Technology
(Hindawi, 2015)Neutron interferometry has proved to be a very precise technique for measuring the quantum mechanical phase of a neutron caused by a potential energy difference between two spatially separated neutron paths inside ... -
Neutron limit on the strongly-coupled chameleon field
(American Physical Society, 2016-03-11)The physical origin of the dark energy that causes the accelerated expansion rate of the Universe is one of the major open questions of cosmology. One set of theories postulates the existence of a self-interacting scalar ... -
A New Adaptive Controller for Performance Improvement of Automotive Suspension Systems with MR Dampers
(SAE International, 2014-04-01)A control algorithm is developed for active/semi-active suspensions which can provide more comfort and better handling simultaneously. A weighting parameter is tuned online which is derived from two components - slow and ... -
A new and efficient Solid Phase Microextraction approach for analysis of high fat content food samples using a matrix-compatible coating
(Elsevier, 2017-05-15)The current work presents the optimization of a protocol enabling direct extraction of avocado samples by a new Solid Phase Microextraction matrix compatible coating. In order to further extend the coating life time, ... -
A new approach to rapidly generate random periodic representative volume elements for microstructural assessment of high volume fraction composites
(Elsevier, 2018-07-15)An algorithm based on event-driven molecular dynamics theory was developed to rapidly generate periodic representative volume elements (RVEs) with nonuniform distributions for both unidirectional fibre-reinforced and ... -
New approaches to characterize polymeric oil additives in solution based on pyrene excimer fluorescence
(Wiley, 2017-01-01)Maleated polyolefins (MaPOs) such as maleated ethylene propylene copolymers or polyisobutylene terminated at one end with a succininic anhydride can be used as polymeric dispersants in engine oils after reaction with ... -
A new approximation of Fermi-Dirac integrals of order 1/2 for degenerate semiconductor devices
(Elsevier, 2018-06-01)There had been tremendous growth in the field of Integrated circuits (ICs) in the past fifty years. Scaling laws mandated both lateral and vertical dimensions to be reduced and a steady increase in doping densities. Most ... -
New composite sustainability indices for Cradle-to-Cradle process design: Case study on thinner recovery from waste paint in auto industries
(Elsevier, 2017-11-10)In a conventional chemical process design, the main focus is on the process economy resulting in the generation of huge amounts of waste materials within the process. Such design approach demands end-of-pipe treatment, ... -
A new crystal plasticity framework to simulate the large strain behaviour of aluminum alloys at warm temperatures
(Elsevier, 2018-06-06)To improve metal formability, high temperature forming has become a desired manufacturing process. Phenomenological plasticity models are widely used in this application, however lack good predictive capability concerning ... -
New exact series solutions for transverse vibration of rotationally-restrained orthotropic plates
(Elsevier, 2019-01-01)The exact series solutions of plates with general boundary conditions have been derived by using various methods such as Fourier series expansion, improved Fourier series method, improved superposition method and finite ... -
New Generation of Solid-Phase Microextraction Coatings for Complementary Separation Approaches: A Step toward Comprehensive Metabolomics and Multiresidue Analyses in Complex Matrices
(American Chemical Society, 2017-04-04)In this work, a new generation of solid-phase microextraction (SPME) coatings based on polytetrafluoro-ethylene amorphous fluoroplastics (PTFE AF 2400) as a particle binder is presented. The developed coating was tested ... -
New insight into the allosteric effect of L-tyrosine on mushroom tyrosinase during L-dopa production
(Elsevier, 2018-07-01)Kinetics studies of L-tyrosine (LTy) ortho-hydroxylation by mushroom tyrosinase (MT) confirmed that MT was severely, but not completely, inhibited at higher concentrations of LTy. Despite the availability of the crystal ... -
A New Na+-Dependent RNA-Cleaving DNAzyme with over 1000-fold Rate Acceleration by Ethanol
(Wiley, 2016-01-15)Enzymes working in organic solvents are important for analytical chemistry, catalysis, and mechanistic studies. Although a few protein enzymes are highly active in organic solvents, little is known regarding nucleic ... -
A new perspective on loss to follow-up in failure time and life history studies
(Wiley, 2019-07-24)A framework is proposed for the joint modeling of life history and loss to follow-up (LTF) processes in cohort studies. This framework provides a basis for discussing independence conditions for LTF and censoring and ... -
A New Portable Digital Meniscometer
(Wolters Kluwer, 2014-01)Purpose: The aims of this study were (i) to develop a new portable slit-lamp mounted digital meniscometer (PDM) and (ii) to test its accuracy and repeatability compared to the existing Yokoi et al. videomeniscometer ... -
Nine Challenges In Incorporating The Dynamics Of Behaviour In Infectious Diseases Models
(Elsevier, 2015-03-01)Traditionally, the spread of infectious diseases in human populations has been modelled with static parameters. These parameters, however, can change when individuals change their behaviour. If these changes are themselves ... -
