Generalised prime systems with periodic integer counting function [PDF]

, 2012
We study generalised prime systems (both discrete and continuous) for which the `integer counting function' N(x) has the property that N(x) ¡ cx is periodic for some c > 0. We show that this is extremely rare.

Fast kmer counting table algorithm using perfect hash function: C++ pseudo-code integration into R using Rcpp API

, 2016
Counting kmers (substrings of length k in DNA sequence data) is an essential component of many methods in bioinformatics, including data preprocessing for de novo assembly, repeat detection, and sequencing coverage estimation. We proposed a simple algorithm to calculate the kmer count using perfect hash table implemented in C++ and using Rcpp API to be

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

FEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Compact-eight channel photon counting module with monolithic array detector

, 2007
We present a multichannel photon counting module that exploits a monolithic array of single-photon avalanche diodes (SPADs). The detector array consists of eight 50μm diameter SPADs featuring low dark counting rate and high photon detection efficiency ...

A heuristic formula for the prime counting function

Using heuristic methods we create a simple but exact formula for the prime counting function. Then we make an asymptotic approximation of this new formula for the prime counting function using two distributions \(H(z)\) and \(h(z)\), which are defined ...

FSCA-YOLO: An Enhanced YOLO-Based Model for Multi-Target Dairy Cow Behavior Recognition

Animals
In real-world dairy farming environments, object recognition models often suffer from missed or false detections due to complex backgrounds and cow occlusions.

MicroRNA-155 promotes glioma cell proliferation via the regulation of MXI1.

PLoS ONE, 2013
Gliomas are the most common and aggressive primary tumors in the central nervous system. Recently, Max interactor-1 (MXI1), an antagonist of c-Myc that is involved in brain tumor progression, has been reported to be deregulated in a variety of tumors ...

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

FEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.
