Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

FEBS Open Bio, EarlyView.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

The formal solutions of Diophantine equation agy = bx + c

Heliyon
We develop a novel method to completely solve the 3-term partial exponential Diophantine equation that represents a generalization of the standard discrete logarithm problem.

Security analysis of elliptic curves with embedding degree 1 proposed in PLOS ONE 2016.

PLoS ONE, 2019
Wang et al. proposed a method for obtaining elliptic curves with embedding degree 1 for securing critical infrastructures, and presented several elliptic curves generated by their method with torsion points of 160 bits and 189 bits orders.

Shor's Algorithm Using Efficient Approximate Quantum Fourier Transform

IEEE Transactions on Quantum Engineering, 2023
Shor's algorithm solves the integer factoring and discrete logarithm problems in polynomial time. Therefore, the evaluation of Shor's algorithm is essential for evaluating the security of currently used public-key cryptosystems because the ...

Pharmacological inhibition of the PERK pathway modulates hepatocellular carcinoma growth and immune signaling

FEBS Open Bio, EarlyView.
Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

Transformation of Elliptic Curve Discrete Logarithm Problem to QUBO Using Direct Method in Quantum Annealing Applications

Journal of Telecommunications and Information Technology
This paper investigates how to reduce the elliptic curve discrete logarithm problem over prime fields to the quadratic unconstrained binary optimization (QUBO) problem in order to obtain as few logical qubits as possible. In the best case scenario, if n

Algorithm of the electronic sign-code signature on the basis of the composition of existing complexities [PDF]

E3S Web of Conferences
The article developed a new algorithm for electronic digital signature in the composition of existing difficulties: discrete logarithm in a finite field, addition of points with rational coordinates of the elliptic curve.

Realization of coprocessor which supports counting of discrete logarithm on elliptic curves with partial knowledge [PDF]

Biuletyn Wojskowej Akademii Technicznej, 2017
In this paper we analyse realization of a coprocessor which supports counting of discrete logarithm on elliptic curves over the field FG(p), where p is the large prime, in FPGA. Main idea of the realization is based on using modules which are able to add

Complementarity of Long‐Reads and Optical Mapping in Parkinson's Disease for Structural Variants

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Long‐read sequencing and optical genome mapping technologies have the ability to detect large and complex structural variants. This has led to the discovery of novel pathogenic variants in neurodegenerative movement disorders. Thus, we aimed to systematically compare the SV detection capabilities of OGM and ONT in Parkinson's disease.
