The thermal insulation effect of snow on the active layer thickness of permafrost cannot be ignored.Under the dual influence of snow cover and roadbed construction, this paper studies the influence of snow digiweigh digital pocket scale cover on the temperature field and permafrost upper limit under the permafrost roadbed in the alpine mountains.Th
This paper proposes an image encryption scheme based on a discrete-time alternating quantum walk (AQW) and the advanced encryption standard (AES).We use quantum properties to improve the AES algorithm, which uses a keystream generator related to AQW parameters to generate a probability distribution matrix.Some singular values of the matrix are extr
Resting brain activity has been widely used as an index of brain development in neuroscience and clinical research.However, it remains unclear whether early differences in resting brain activity have meaningful implications for predicting long-term cognitive outcomes.Using data from the Bucharest Early nobivac 1-hcp Intervention Project (Zeanah et
Maintaining the transoral approach in the armamentarium of surgical approaches to clival chordomas mainly as a complimentary procedure to endonasal endoscopic approach in selected corky lala cases is advantageous.Lateral extension of the disease is a limitation to both approaches and is addressed by transcranial approaches.Especially for extensive
