PURPOSE To examine distributed patterns of language processing in healthy controls and patients with epilepsy using magnetoencephalography (MEG), and to evaluate the concordance between laterality of distributed MEG sources and language laterality as determined by the intracarotid amobarbital procedure (IAP). METHODS MEG was performed in 10 healthy controls using an anatomically constrained, ...

In [N. Ujević, New iterative method for solving linear systems, Appl. Math. Comput. 179 (2006) 725730], a new iterative method for solving linear system of equations was presented which can be considered as a modification of the Gauss-Seidel method. Then in [Y.-F. Jing and T.-Z. Huang, On a new iterative method for solving linear systems and comparison results, J. Comput. Appl. Math., In press]...

This article proposes and implements a class of chaotic motors for electric compaction. The key is to develop a design approach for the permanent magnets PMs of doubly salient PM DSPM motors in such a way that chaotic motion can be naturally produced. The bifurcation diagram is employed to derive the threshold of chaoization in terms of PM flux, while the corresponding phase-plane trajectories ...

 This article proposes a new dual-sided permanent magnet (DSPM) machine with flux-concentrated U-shaped magnets (PMs) in stator, and consequent-pole PMs rotor, respectively. The proposed DSPM can perform bidirectional field modulation effect (BFME) to enhance the effective harmonics, hence improving torque capability. A magneto-motive force-permeance based model is employed reveal produc...

This article presents a novel doubly salient permanent magnet (DSPM) machine with enhanced torque performance. The key is that an assistive magnetic flux produced by using two sets of slot PMs inserted into the openings, which can effectively improve production. Besides, complementary path built dual rotors 180° angle shift to reduce leakage flux, suppress ripple. In this article, proposed desi...

The DSPM&DE (Donnan steric pore model and dielectric exclusion) model was employed to predict the rejection of six haloacetic acids (HAAs) and six pharmaceuticals (PhACs), selected to have different molecular weight, hydrophobicity and charge, by two commercial nanofiltration (NF) membranes (HL and NF270). Increasing filtration pressures were applied to vary the rejection ratios. Glucose and Na...

Introduction In low-income and middle-income countries, it is estimated that one in every three preschool-age children are failing to meet cognitive or socioemotional developmental milestones. Thailand has implemented a universal national developmental screening programme (DSPM) for young children to enable detection of developmental disorders and early intervention that can improve child healt...

One of the most well-established frameworks for modeling multicomponent transport in nanofiltration (NF) is Donnan-Steric Pore Model with Dielectric Exclusion (DSPM-DE). Conventional DSPM-DE characterizes across NF membranes through four governing membrane parameters: (1) pore radius; (2) effective thickness; (3) charge density; and (4) dielectric constant inside pores. The process quantifying ...
