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.

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

Efficient Search for Optimal Diffusion Layers of Generalized Feistel Networks

IACR Transactions on Symmetric Cryptology, 2019
The Feistel construction is one of the most studied ways of building block ciphers. Several generalizations were then proposed in the literature, leading to the Generalized Feistel Network, where the round function first applies a classical Feistel ...

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 ...

Security evaluation on type‐1 and type‐1‐like 4‐branch generalized Feistel structures and application to reduced‐round Lesamnta‐LW‐BC

IET Information Security, 2022
Generalized Feistel structures (called GFSs for short) are one of the most popular block cipher structures. They are mainly divided into type‐1, type‐2 and type‐3 GFS.

The influence of hydrological seasonality and land use and cover on the relationship between dissolved organic carbon and carbon dioxide along a karst‐draining large tropical river

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.

Investigation of the Thermal Conductivity of Dry and Icy Lunar Regolith Simulants

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract This study investigates the thermal conductivity of lunar regolith simulants, both with and without the addition of ice. A novel icy regolith simulant was developed, combining microgranular water ice particles and lunar highlands simulant LHS‐1.

Quantum Distinguishing Attacks against Type-1 Generalized Feistel Ciphers [PDF]

, 2019
A generalized Feistel cipher is one of the methods to construct block ciphers, and it has several variants. Dong, Li, and Wang showed quantum distinguishing attacks against the $(2d-1)$-round Type-1 generalized Feistel cipher with quantum chosen ...
