A compact nanosecond pulse generator for x-ray radiographies.

A compact nanosecond pulse generator was developed, aiming at producing high-energy flash x rays with a long lifetime. The generator was designed on the basis of a 0.67-ns pulse forming line (PFL), which is charged to ∼700 kV by an air core Tesla transformer and switched by a fast spark gap.

Systematic review and Meta-analysis of treating open angle glaucoma with gonioscopy-assisted transluminal trabeculotomy.

Aim: To systematically review and Meta-analyze studies of managing open angle glaucoma (OAG) with gonioscopy-assisted transluminal trabeculotomy (GATT) and to evaluate its effectiveness and safety.

Methods: Eligible studies were retrieved and screened from five main electronic databases. Mean difference (MD) was hired to show the pooled effectiveness of intraocular pressure (IOP) and medication decrease achieved by GATT.

Symmetry reduction and exact solutions of two higher-dimensional nonlinear evolution equations.

In this paper, symmetries and symmetry reduction of two higher-dimensional nonlinear evolution equations (NLEEs) are obtained by Lie group method. These NLEEs play an important role in nonlinear sciences. We derive exact solutions to these NLEEs via the [Formula: see text]-expansion method and complex method.

Some new traveling wave exact solutions of the (2+1)-dimensional Boiti-Leon-Pempinelli equations.

We employ the complex method to obtain all meromorphic exact solutions of complex (2+1)-dimensional Boiti-Leon-Pempinelli equations (BLP system of equations). The idea introduced in this paper can be applied to other nonlinear evolution equations. Our results show that all rational and simply periodic traveling wave exact solutions of the equations (BLP) are solitary wave solutions, the complex method is simpler than other methods, and there exist some rational solutions ur,2 (z) and simply periodic solutions us,2-6(z) which are not only new but also not degenerated successively by the elliptic function solutions.
