Turbulence Characteristics of Ice‐Free Radiatively Driven Convection in a Deep, Unstratified Lake
Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.Abstract This study examines data collected with an autonomous underwater glider during a period of vigorous radiatively driven convection (RDC) and low winds in deep, unstratified Lake Superior. Conductivity, temperature and depth (CTD) measurements reveal distinct convective plumes of warm downwelling water with temperature anomalies of ∼0.1° ${\sim}

Accounting for Compound Flooding Can Prevent Maladaptation—A Baltic Sea Case Study
Earth's Future, Volume 13, Issue 2, February 2025.Abstract Estuarine areas are currently at risk of compound flooding, the frequency and intensity of which is expected to increase with climate change. Even though efforts are made to adapt against single flood drivers using hard protection, potential subsequent changes in flood risk due to compound flooding are often overlooked in flood risk ...

, 2001 . In this paper, we propose a new symmetric key block cipher SC2000 with 128-bit block length and 128-,192-,256-bit key lengths. The block cipher is constructed by piling two layers: one is a Feistel structure layer and the other is an SPN structure ...

Differential Attacks on Generalized Feistel Schemes [PDF]
, 2011 While generic attacks on classical Feistel schemes and unbalanced Feistel schemes have been studied a lot, generic attacks on several generalized Feistel schemes like type-1, type-2 and type-3 and Alternating Feistel schemes, as defined in~\cite{HR ...

Quantum cryptanalysis of ciphers based on generalized Feistel and Lai-Massey schemes [PDF]
This paper investigates generalizations of the Lai-Massey scheme, including unified constructionscombining it with the Feistel scheme (MD GLM, UFLM, L-Feistel, and quasi-Feistel). New reductionsto the quasi-Feistel scheme are provided.

Links between Quantum Distinguishers Based on Simon’s Algorithm and Truncated Differentials
IACR Transactions on Symmetric CryptologyIn 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

Comparing Cryptographic Algorithms in Scalable Feistel Networks [PDF]
, 2010 Scalability of symmetric cipher is still not asnatural as for public-key cryptosystems. Most of thecurrent block ciphers do not support freely variableblock and key lengths.

Cryptanalysis of reduced QTL block cipher [PDF]
, 2017 Recently, a new ultra lightweight block cipher called QTL has been proposed. The authors claim to achieve a fast diffusion in QTL by using a new variant of a generalized Feistel network structure that changes all block messages in one iterative round in ...
