Abstract Nonlinear optical (NLO) materials are the vital components of future photoelectric technologies as they can broaden tunable wavelength range supplied by common laser sources. However, necessary prerequisites for a practical NLO material rather strict. Accordingly, considerable efforts have been focused on finding potential materials. Here we report two asymmetric beryllium-free borates Pna 2 1 - and P $$\bar 6$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mover>...

Abstract The transient electromagnetic method (TEM) is a geophysical exploration that can efficiently acquire subsurface electrical parameters. For airborne, towed and other mobile platforms, TEM systems, large data volumes the traditional one-dimensional denoising with low efficiency signal-to-noise ratio (SNR) of late-time are main bottlenecks limiting its reliable application. To address this problem, paper proposes neural network structure suitable for two-dimensional (2D) processing....

The preparation of polycyclic aromatic hydrocarbons (PAHs) by the Scholl reaction is typically performed using superstoichiometric oxidants.

A distributed phase measurement method of frequency-domain electromagnetic detection is proposed. The theoretical analysis the previous literature shows that in applications, as an independent parameter can reduce diversity solution, and it also has advantage greater steepness than amplitude. Currently, there are few dealing with practical application audio detection, because difficult to obtain from separated devices. synchronization recording system designed based on most widely used GPS...

The transient electromagnetic method (TEM) is one of the geophysical methods that can quickly detect underground space information. It obtains resistivity structure medium by inversion technology. traditional only give a unique solution conforming to TEM data, but cannot solve multiplicity problem solutions. Bayesian technology provide uncertainty information this problem. However, its long calculation time makes it difficult apply engineering detection with high real-time performance. To...

The mutual interaction among multiple fish during schooling has significant implication on motion pattern control and hydrodynamic optimization. However, the collective of objects in a flow field forms vast parameter space, causing difficulty comprehensively analyzing considering each parameter. To address this issue, problem is simplified to foil pair oscillating side-by-side configuration two-dimensional flow. Moreover, Gaussian process regression predictive algorithm combined with fast...
