Snapshots of Motion: A Novel Structural Intermediate Reveals Conserved Dynamics in Archaeal DNA Ligases

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 6, Page 1245-1258, June 2026.
ABSTRACT We present the first x‐ray crystallographic structural evidence of an archaeal DNA ligase showing the AMP covalent adduct together with further cofactor hydrolysis, capturing a transient intermediary in the first step of the ligation reaction, triggered by the pyrophosphate hydrolysis.

High Entropy Wide‐Bandgap Borates with Broadband Luminescence and Large Nonlinear Optical properties

Advanced Functional Materials, Volume 36, Issue 35, 30 April 2026.
High‐entropy rare‐earth borates exhibit excellent nonlinear optical and broadband luminescence properties arising from multi‐component doping, chemical disorder, increased configurational entropy, and increased lattice and electronic anharmonicity. This formulation enabled us to obtain a large, environmentally stable single crystal with 3X higher laser‐

The Evolution of a Polar Cap Patch Into a Blob in the Nightside Ionosphere: Direct Observations of Multiple Blob Formation Mechanisms Acting Simultaneously on the Same Plasma

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract A polar cap patch was observed to exit the polar cap to become a blob as it entered the auroral oval on the nightside of the Earth under moderately quiet geomagnetic conditions (Kp = 3−). Auroral particle precipitation led to an increase in the electron density of the blob.

A Novel Higher Order Local Time‐Stepping Technique for the DGTD–FDTD Method

Electronics Letters, Volume 62, Issue 1, January/December 2026.
A novel higher order local time‐stepping (LTS) technique is developed for the DGTD–FDTD (discontinuous Galerkin time‐domain–finite difference time‐domain) method to accelerate transient electromagnetic simulations. By applying a higher order equation to boundary elements between LTS classes, the method reduces approximation errors caused by LTS.

Accelerating NTT with RISC-V Vector Extension for Fully Homomorphic Encryption

Transactions on Cryptographic Hardware and Embedded Systems
Fully Homomorphic Encryption (FHE) has gained increasing importance mainly due to its potential use in privacy-preserving cloud computing. This privacy stems from the computation being directly performed on data that is encrypted by the client. However,

On the exact decryption range for Gentry–Halevi's implementation of fully homomorphic encryption

Journal of Mathematical Cryptology, 2014
In this paper, we revisit the fully homomorphic encryption (FHE) scheme implemented by Gentry and Halevi, which is just an instantiation of Gentry's original scheme based on ideal lattices.

Differential Attacks by Algebraic Solving on a Series of HE‐Friendly Stream Ciphers

IET Information Security, Volume 2026, Issue 1, 2026.
In recent years, many symmetric encryption ciphers have been proposed for homomorphic encryption (HE) applications. Rasta and its variants Masta and Pasta have gradually become a self‐contained series of HE‐friendly stream ciphers. The feature of these ciphers is that a fresh affine layer is randomly generated for each encryption.
