The effect of hold time of overload on crack propagation behavior emerging from notch root [PDF]
FME Transactions, 2016 In the present study the crack propagation behavior under constant amplitude loads emerging from the notch root after being overloaded and held in a certain period of time was investigated.

Analysis of Sound Absorbing Properties of Activated Carbon Fiber Felts Based on Density Change
Nantong Daxue xuebao. Ziran kexue ban, 2021 In order to study the sound absorbing properties of activated carbon fiber felts, three kinds of activated carbon fiber felts with different densities were selected, and the double channel acoustic analyzer with impedance tube was used to test the ...

Random fractional Fourier transform : stochastic perturbations along the axis of propagation
, 1999 The fractional Fourier transform (FRT) is known to be optically implementable with use of a medium with a perfect radial quadratic-index profile. Using the quantum-mechanical operator formalism, we examine the effects on the FRT action of such a medium

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Constant Propagation on the Value Graph: Simple Constants and Beyond [PDF]
, 2000 We present a new algorithm for constant propagation (CP), which works on the value graph of a program. This algorithm combines the (1) efficiency of the sparse CP-algorithms of Reif and Lewis, Ferrante and Ottenstein, and Weg man and Zadeck with the (2) conceptual simplicity of their classic conventional counterparts of Kildall, and Kam and Ullman ...

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

A numerical investigation of constant-volume non-Boussinesq density currents [PDF]
, 2010 The time-dependent behaviour of non-Boussinesq high-Reynolds-number density currents of density ρc, released from a lock of height h₀ and length x₀ into a ambient of height H and density ρₐ, is considered. We use two dimensional Navier-Stokes simulations

FEBS Letters, EarlyView.An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...
