Analysis of structural dynamic data from Skylab. Volume 2: Skylab analytical and test model data [PDF]

open access: yes
The orbital configuration test modal data, analytical test correlation modal data, and analytical flight configuration modal data are presented. Tables showing the generalized mass contributions (GMCs) for each of the thirty tests modes are given along ...

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

open access: yesFEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Output‐only damage detection using vehicle‐induced displacement response and mode shape curvature index

open access: yes, 2016
Most of the existing bridge superstructure damage detection methods are based on acceleration or strain response due to ambient excitation. This paper proposes a bridge damage detection procedure that utilizes vehicle‐induced displacement response ...

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

MODE SHAPE ANALYSIS OF MULTIPLE CRACKED FUNCTIONALLY GRADED TIMOSHENKO BEAMS

open access: yes, 2017
THE PRESENT PAPER ADDRESSES FREE VIBRATION OF MULTIPLE CRACKED TIMOSHENKO BEAMS MADE OF FUNCTIONALLY GRADED MATERIAL (FGM). CRACKS ARE MODELED BY ROTATIONAL SPRING OF STIFFNESS CALCULATED FROM THE CRACK DEPTH AND MATERIAL PROPERTIES VARY ACCORDING TO THE

Development of inverse inviscid transonic solution methods [PDF]

open access: yes
A numerical method suitable for the analysis and/or design of supercritical transonic airfoils is reported. In order to achieve accuracy, the method utilizes the full inviscid potential flow equations; and in order to remain simple it solves the problem ...

Real‐time assay of ribonucleotide reductase activity with a fluorescent RNA aptamer

open access: yesFEBS Letters, EarlyView.
Ribonucleotide reductases (RNR) synthesize DNA building blocks de novo, making them crucial in DNA replication and drug targeting. FLARE introduces the first single‐tube real‐time coupled RNR assay, which enables isothermal tracking of RNR activity at nanomolar enzyme levels and allows the reconstruction of allosteric regulatory patterns and rapid ...

Structural Damage Detection by Using Single Natural Frequency and the Corresponding Mode Shape

open access: yes, 2016
Damage can be identified using generalized flexibility matrix based methods, by using the first natural frequency and the corresponding mode shape. However, the first mode is not always appropriate to be used in damage detection. The contact interface of
