The study of the deformation and damage evolution behaviour of surrounding rock under excavation unloading conditions is of vital importance for a deep understanding of the mechanism of roadway failure. In this study, unloading testing using a partia

In our manuscript, we aim to investigate dark soliton behavior for the (2+1)-dimensional Davey–Stewartson-like equations with variable coefficients, which can be applied to the Bose-Einstein condensates or ultra-relativistic degenerate dense plasma

A preliminary design of a mega-electron-volt (MeV) monochromator with 10−5 energy spread for ultrafast electron diffraction (UED) and ultrafast electron microscopy (UEM) is presented. Such a narrow energy spread is advantageous in both the single s

Under investigation in this paper are the three-component Gross-Pitaevskii equations in the spinor Bose-Einstein condensate. We derive the one- and two-soliton solutions for the one, two and three components of the spinor Bose-Einstein condensate. We

In this article, we report our proof-of-principle design and experimental commissioning of a broadly tunable and low-cost transverse focusing lens system for MeV-energy electron beams. The lens system based on electromagnetic (EM) quadrupoles has bee

We explore the possibility of visualizing the lattice dynamics behavior by acquiring a single time-resolved mega-electron-volt ultrafast electron diffraction (UED) image. Conventionally, multiple UED shots with varying time delays are needed to map o

Dark solitons in the inhomogeneous optical fiber are studied in this manuscript via a higher-order nonlinear Schrödinger equation, since dark solitons can be applied in waveguide optics as dynamic switches and junctions or optical logic devices. Bas

The absorption and scattering behaviors are two fundamental concerns for artificial metamaterials (MMs) toward a variety of applications like radar, antennas, stealth, wireless communication, etc. Here we propose a metasurface with dynamical control

This paper presents the design of a 6th-order continuous-time bandpass delta-sigma modulator that achieves in simulation over 75 dB SNDR across 25-MHz bandwidth with a center frequency at 250 MHz. On the architectural level, the SNR-limiting factor i
