Enhancing Atomic‐Resolution in Electron Microscopy: A Deep Learning Denoiser Operating in the Frequency Domain

open access: yesAdvanced Intelligent Systems, EarlyView.
The newly developed AI‐automated Fast Fourier Transform denoising algorithm surpasses conventional real‐space methods by revealing even light atoms otherwise hidden in noisy backgrounds. Atomic resolution electron microscopy has become an essential tool for many scientific fields, when direct visualization of atomic arrangements and defects is needed ...

On a generalization of the Gadovan numbers [PDF]

open access: yesMathematica Moravica
In this paper, we define (k, l)-Gadovan numbers. We give the Binet-like formula, the generating functions, the exponential generating function of the (k, l)-Gadovan numbers. Also, we derive Cassinilike identity, Catalan-like identity, Vajda-like identity,

Biallelic Germline Inactivation of HROB Causes Primary Gonadal Insufficiency and is Potentially Associated with Colonic Polyposis Predisposition

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The Homologous Recombination Factor With OB‐Fold (HROB) plays a role in homologous recombination and DNA replication, where it enhances the MCM8‐MCM9 helicase complex activity. Recent findings link biallelic germline HROB variants to primary gonadal insufficiency (hypergonadotropic hypogonadism), a phenotype also associated with MCM8/MCM9 ...

Proofs of two conjectures involving sums of normalized Narayana numbers

open access: yesDemonstratio Mathematica
Narayana numbers are well-known and have many applications in the field of combinatorics. The Narayana numbers form a triangular array, where the sum of the nth row is the nth Catalan number.

Generalized Catalan numbers

open access: yes, 2020
A finitization of the Catalan numbers $ C_n $ can be defined as Euler characteristics of an algebraic structure. We conjecture the existence of a $ q $-deformed version of such structure, and provide evidence for the first two non-trivial cases. This $ q $-deformed version will likely categorify series arise from identities of the Roger-Ramanujan type.

Clock genes regulate Ca2+ signaling and mitochondrial bioenergetics to inhibit Sjogren's disease

open access: yesArthritis &Rheumatology, Accepted Article.
Objective Although Ca2+ signaling and metabolism have been identified as key determinants for the development of Sjogren's disease (SjD), the intricate connection between them and salivary gland physiology remains poorly understood. Methods Fluorescence‐based Ca2+ imaging, RNA seq, and mitochondrial activity were used to investigate the effects of ...

Simple Rules of a Discrete Stochastic Process Leading to Catalan-like Recurrences

open access: yesAlgorithms
A method for obtaining integer sequences is presented by defining simple rules for the evolution of a discrete dynamical system. This paper demonstrates that various Catalan-like recurrences of known integer sequences can be obtained from a single ...
