Assessing the Speciation of Lutjanus campechanus and Lutjanus purpureus through Otolith Shape and Genetic Analyses

open access: yesFishes, 2022
Based on their morphological and genetic similarity, several studies have proposed that Lutjanus campechanus and Lutjanus purpureus are the same species, but there is no confirmed consensus yet.

Structural and biochemical analysis of a B12 superbinder

open access: yesFEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Response Prediction of VFPI Through Equivalent Long Period Wavelet of Near-Fault Ground Motion

open access: yesElectronic Journal of Structural Engineering, 2022
Past research has revealed that a Variable Frequency Pendulum Isolator (VFPI) effectively controls the structural responses such as base shear and structural acceleration under far and near fault earthquakes and the VFPI may show excessive sliding ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Fringe pattern analysis using a one-dimensional modified Morlet continuous wavelet transform [PDF]

open access: yes, 2008
This paper proposes the use of a modified Morlet wavelet in order to demodulate fringe patterns in conjunction with the one-dimensional continuous wavelet transform (1D-CWT). Our investigations demonstrate that the modified Morlet wavelet produces better

A New Approach of Power System Protection Based on Wavelet Transformation [PDF]

open access: yesJournal of Electrical and Electronics Engineering, 2016
Wavelet transformation has been used in many protection applications such as transmission lines, transformers and generators protection. In the previous researches, the technique of wavelet protection was applied only to protect one element of the power ...

ELD analysis under tropical climate using wavelet and regression approaches for power management: Indonesia case study

open access: yesInternational Journal of Sustainable Engineering, 2023
The weather conditions in one location can affect consumption patterns and the volume of electricity load demand (ELD) on power systems. This paper presents a wavelet-regression method to analyse the characteristic of ELD in Indonesia towards weather ...

ADP‐ribosylation: An emerging regulator of the epigenome

open access: yesMolecular Oncology, EarlyView.
ADP‐ribosylation has emerged as a dynamic epigenetic signaling mechanism that modifies histones and chromatin‐associated proteins. Through coordinated PARylation and MARylation, it integrates with other histone modifications to regulate chromatin structure, transcription factor activity, and gene expression, influencing genome function and disease ...
