Noise refocusing in a five-blade neutron interferometer
(AIP Publishing, 2017-08-07)We provide a quantum information description of a proposed five-blade neutron interferometer geometry and show that it is robust against low-frequency mechanical vibrations and dephasing due to the dynamical phase. The ... -
Non-invasive brain stimulation interventions for management of chronic central neuropathic pain: a scoping review protocol
(BMJ Publishing Group, 2017-10-16)Introduction Pain can affect people regardless of age, gender or ethnicity. Chronic central neuropathic pain (CCNP) is a debilitating condition that affects populations such as stroke survivors, amputees, spinal cord injury ... -
Non-linear, non-monotonic effect of nano-scale roughness on particle deposition in absence of an energy barrier: Experiments and modeling
(Springer Nature, 2015-12-11)Deposition of colloidal- and nano-scale particles on surfaces is critical to numerous natural and engineered environmental, health, and industrial applications ranging from drinking water treatment to semi-conductor ... -
A non-local plasticity model of stimulated volume evolution during hydraulic fracturing
(Elsevier, 2018-10-02)Hydraulic fracturing in naturally fractured rocks often leads to the creation of a stimulated zone in which the target rock formation is deformed and fractured by the reactivation and shear dilation of natural fractures ... -
Nonlinear electrokinetic motion of electrically induced Janus droplets in microchannels
(Elsevier, 2019-03-07)The nonlinear electrokinetic motion of electrically induced Janus droplets (EIJDs) in a microchannel is studied in this paper. The EIJDs were fabricated by operating the positively charged aluminum oxide nanoparticles to ... -
Nonlinear model predictive control of a multiscale thin film deposition process using artificial neural networks
(Elsevier, 2019-11-02)The purpose of this study was to employ Artificial Neural Networks (ANNs) to develop data-driven models that would enable the shrinking horizon nonlinear model predictive control of a computationally intensive stochastic ... -
Nonsmooth Bifurcations of Mean Field Systems of Two-Dimensional Integrate and Fire Neurons
(Society for Industrial and Applied Mathematics, 2016)Mean field systems have recently been derived that adequately predict the behaviors of large networks of coupled integrate-and-fire neurons [W. Nicola and S.A. Campbell, J. Comput. Neurosci., 35 (2013), pp. 87-108]. The ... -
Nonsmooth Modeling of Vibro-Impacting Euler-Bernoulli Beam
(Hindawi, 2012-06-17)A new technique to simulate nonsmooth motions occurring in vibro-impacting continuous systems is proposed. Sticking motions that are encountered during vibro-impact simulation are imposed exactly using a Lagrange multiplier, ... -
Normal Mode Spectra of Idealized Baroclinic Waves
(AMS, 2020-02-01)Normal modes are used to investigate the contributions of geostrophic vortices and inertia–gravity waves to the energy spectrum of an idealized baroclinic wave simulation. The geostrophic and ageostrophic modal spectra ... -
Normal operators with highly incompatible off-diagonal corners
(Polish Academy of Sciences, 2020-05-25)Let H be a complex, separable Hilbert space, and B(H) denote the set of all bounded linear operators on H. Given an orthogonal projection P∈B(H) and an operator D∈B(H), we may write D=[D1D3D2D4] relative to the decomposition ... -
Normalized Connectomes Show Increased Synchronizability with Age through Their Second Largest Eigenvalue
(Society for Industrial and Applied Mathematics, 2021-01)The synchronization of different brain regions is widely observed under both normal and pathological conditions, such as epilepsy. However, the relationship between the dynamics of these brain regions, the connectivity ... -
Normative kinematics of reaching and dexterity tasks: moving towards a quantitative baseline for Functional Capacity Evaluations(FCEs)
(Taylor and Francis, 2017-12-15)Purpose: This work generates a comprehensive description of upper extremity and torso kinematics of a healthy population during reaching and dexterity Functional Capacity Evaluation (FCE) tasks. Methods: Upper limb and ... -
Not so fast: Individual differences in impulsiveness are only a modest predictor of cognitive reflection
(Elsevier, 2020-02-01)The extent to which a person engages in reflective thinking while problem-solving is often measured using the Cognitive Reflection Test (CRT; Frederick, 2005). Some past research has attributed poorer performance on the ... -
A note on character sums in finite fields
(Elsevier, 2017-07)We prove a character sum estimate in Fq[t] and answer a question of Shparlinski. -
A note on intersecting hypergraphs with large cover number
(The Electronic Journal of Combinatorics, 2017-08-11)We give a construction of r-partite r-uniform intersecting hypergraphs with cover number at least r−4 for all but finitely many r. This answers a question of Abu-Khazneh, Barát, Pokrovskiy and Szabó, and shows that a ... -
A note on simplicial cliques
(Elsevier, 2021-09)Motivated by an application in condensed matter physics and quantum information theory, we prove that every non-null even-hole-free claw-free graph has a simplicial clique, that is, a clique K such that for every vertex v ... -
