A Vibration Reliability Analysis Method for the Uncertain Space Beam Structure

open access: yesShock and Vibration, 2016
Considering that uncertainty is inherent and unavoidable in engineering practice and the available information about the uncertain parameters is always not sufficient, the paper tries to carry out the nonprobabilistic vibration reliability analysis so as

Bounds for index of a modified graph

open access: yesDiscussiones Mathematicae Graph Theory, 2004
Summary: If a graph is connected then the largest eigenvalue (i.e., index) generally changes (decreases or increases) if some local modifications are performed. In this paper two types of modifications are considered: (i) for a fixed vertex, \(t\) edges incident with it are deleted, while \(s\) new edges incident with it are inserted; (ii) for two non ...

Bounds for the Hosoya Index

open access: yesZeitschrift für Naturforschung A, 1987
Some inequalities for Hosoya's topological index are deduced, revealing its dependence on the structure of the carbon-atom sekeleton of a hydrocarbon molecule.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Boundedness of l-index of analytic curves [PDF]

open access: yesМатематичні Студії, 2011
We introduce a concept of an analytic curve of bounded l-index and investigate possible growth of such curves. Moreover, l-index boundedness of analytic curves satisfying linear differential equations is investigated.

Bayesian Forecasting of Bounded Poisson Distributed Time Series

open access: yesEntropy, 2023
This research models and forecasts bounded ordinal time series data that can appear in various contexts, such as air quality index (AQI) levels, economic situations, and credit ratings. This class of time series data is characterized by being bounded and

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

On Set-Valued Complementarity Problems

open access: yesAbstract and Applied Analysis, 2013
This paper investigates the set-valued complementarity problems (SVCP) which poses rather different features from those that classical complementarity problems hold, due to tthe fact that he index set is not fixed, but dependent on .

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

open access: yesFEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.
