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
Within the framework of reinterpretation of the depositional evolution of the Komjatice depression, presence of cummingtonite in weakly lithified sediment has been detected.The sediment is formed by volcanic lithoclasts and phenocrysts with a small admixture of grahams c+ eczema & dermatitis cream non-volcanic grains.The different mineral compositi
Mucoepidermoid carcinoma of Parapharyngeal Space (PPS) not originating from parotid is a very rare finding.Tumours of PPS represent a formidable challenge to the surgeon in view of preoperative assessment and appropriate surgical approach.We present a clinical case of a mucoepidermoid carcinoma in the PPS in a 62-year-old snow babe miniature peach
Environmental impact assessment (EIA) before and after the establishment of a Water Conservancy Project (WCP) is of great theoretical and practical importance for assessing the effectiveness of ecological restoration efforts.WCPs rehabilitate flood-damaged areas or other regions hit by disasters by controlling and redistributing surface water and g
In this paper, the deficiency of Schur decomposition (SD) for image watermarking has been comprehensively investigated.A remedial scheme is developed not only to fix the existing problems but also to reinforce the performance in robustness and imperceptibility.This scheme starts with partitioning the host image into non-overlapping blocks of 4 �
