Current conception of attosecond pulse is based on Fourier optics and refers to an electromagnetic pulse with a broad, homogeneous weight Fourier spectrum.Its preparation/generation is along an indirect route in which the output of commercial available μ m-level wavelength laser is “processed„ by elaborately designed optics medium

This study aimed to draw up a risk map of predicting the potential failure zone and impulse that may occur due to the fall of trees in the palace.The main findings of the study are as follows.First, a formula for calculating a failure zone and impulse that would occur in the fall of trees was established.The potential failure zone was calculated wi

In the field of wireless communication, transmitter localization technology is crucial for achieving accurate source tracking.However, the extant methodologies for localization face numerous challenges in wireless sensor networks (WSNs), particularly due to the constraints posed by the sparse distribution of sensors across large areas.We present DS
