Feistel Ciphers with L 2-Decorrelation [PDF]
, 1999 Recently, we showed how to strengthen block ciphers by decorrelation techniques. In particular, we proposed two practical block ciphers, one based on the GF(2n)-arithmetics, the other based on the x mod p mod 2n primitive with a prime p = 2n(1 + δ). In this paper we show how to achieve similar decorrelation with a prime p = 2n(1 - δ).

Improvement of the Minimal‐Guess‐Basis MILP Model and Its Application to ESF
IET Information Security, Volume 2026, Issue 1, 2026.The guess‐and‐determine technique find wide applications in the recovery of unknown variables within given system of relations. The fundamental concept behind this technique involves guessing certain unknown variables and deducing the remaining ones based on the relational system.

Metabolism of Epoxidised Withanolides by a Generalist and a Specialist Insect Species
ChemistryOpen, Volume 14, Issue 12, December 2025.Larvae of Heliothis (Chloridea) virescence and subflexa have the ability to convert the epoxidized terpenoid 4β‐hydroxywithanolide E (4BHWE) to withanolide S. The conversion is found by feeding the larvae an artificial diet supplemented with 13C‐labeled 4BHWE.

A Brief Note on Supercooled Glacial Deep Waters
Paleoceanography and Paleoclimatology, Volume 40, Issue 12, December 2025.Abstract According to hydrographic profiles, approximately 2%–5% of the present‐day deep Southern Ocean contains supercooled waters that are below the freezing point. Which role these supercooled waters may have played under glacial conditions is an open question.

Oxygen Isotope Insights Into the Impact of Amundsen Sea Freshwater on Ross Sea Freshening
Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.Abstract Over the past five decades, the Ross Sea has freshened, but the mechanisms remain unclear. This study uses oxygen isotopes to trace freshwater transport from the Amundsen Sea to the Ross Sea. Results show that Winter Water (WW) in the Antarctic Slope Current (ASC) has lower δ18O values (<−0.7‰) due to glacial meltwater (GMW) inputs from the ...

Elastic Block Ciphers: The Feistel Cipher Case
, 2004 We discuss the elastic versions of block ciphers whose round function processes subsets of bits from the data block differently, such as occurs in a Feistel network and in MISTY1. We focus on how specific bits are selected to be swapped after each round when forming the elastic version, using an elastic version of MISTY1 and differential cryptanalysis ...

Limnology and Oceanography, Volume 70, Issue 10, Page 2858-2871, October 2025.Abstract The partial pressure of carbon dioxide (pCO2) in rivers is influenced by carbonate weathering, soil CO2, photosynthesis, and the mineralization of dissolved organic carbon (DOC). In tropical regions, elevated temperatures intensify these processes. However, their seasonal dynamics remain poorly understood in large karst‐draining rivers.
