Hydraulics of Channelized Flow in Ice‐Supersaturated Debris: 1. Rock Glacier Hydrology in Alpine Glacial‐Periglacial Systems

Water Resources Research, Volume 61, Issue 2, February 2025.
Abstract Frozen sediment accumulations, including rock glaciers, talus, and moraines, constitute complex aquifers in permafrost‐affected terrain. The spatial distribution of permafrost ice largely governs the flow of water through the subsurface, which exhibits a spectrum of flow patterns, ranging from diffuse flow through a porous matrix to ...

Interactions Between Diurnal Warm Layers and Surface‐Layer Fronts

Journal of Geophysical Research: Oceans, Volume 130, Issue 1, January 2025.
Abstract Previous studies have highlighted the individual importance of diurnal warm layers (DWLs) and surface‐layer fronts within the surface boundary layer (SBL) in regulating energy, momentum, and gas exchange between the atmosphere and the ocean. This study investigates the interactions between DWLs and surface‐layer fronts using field observations

Design of AL-13 Block Cipher Algorithm Based On Extended Feistel Network

Journal of Physics: Conference Series, 2019
In this paper, we design a new block cipher algorithm called AL-13. The structure of AL-13 is simple. We use Extended Feistel Network Type II with input-output 128 bits and key input 256 bits.

Links between Quantum Distinguishers Based on Simon’s Algorithm and Truncated Differentials

IACR Transactions on Symmetric Cryptology
In this paper, we study the quantum security of block ciphers based on Simon’s period-finding quantum algorithm. We explored the relations between periodic functions and truncated differentials. The basic observation is that truncated differentials with
