A MEGASECOPTERON FROM UPPER CARBONIFEROUS STRATA IN SPAIN

A Megasecopteron From Upper Carboniferous Strata in Spain

In 1962 Professor F.Stockmans, of the Institut SELENIUM 50 MCG Royal des Sciences Naturelles de Belgique, kindly sent me for study two insects from Upper Carboniferous deposits in Northern Spain.One of these (no.94.837), from the Mine de Poleiro, is part of a cockroach tegmen, which cannot be placed with certainty even to family level.The other spe

Enhancing Adversarial Transferability With Intermediate Layer Feature Attack on Synthetic Aperture Radar Images

Synthetic aperture radar (SAR) automatic target recognition (ATR) systems based on deep neural network models are vulnerable to adversarial examples.Existing SAR adversarial attack algorithms require access to the network structure, parameters, and training data, which are often inaccessible in real-world scenarios.To address this problem, this stu

Simulation and detection efficiency analysis for measurements of polar mesospheric clouds using a spaceborne wide-field-of-view ultraviolet imager

The variation trends and characteristics of polar mesospheric clouds (PMCs) are important for studying the evolution of atmospheric systems and understanding various atmospheric dynamic processes.Through observation and analysis of PMCs, we can gain a comprehensive understanding of the mechanisms driving atmospheric processes, providing a scientifi
