Open-source digital technologies for low-cost monitoring of historical constructions [PDF]
, 2017 This paper shows new possibilities of using novel, open-source, low-cost platforms for the structural health monitoring of heritage structures. The objective of the study is to present an assessment of increasingly available open-source digital modeling ...

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions
FEBS Letters, EarlyView.We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Geofluids, 2020 Open-pit slopes contain numerous nonpenetrating, intermittent joints which maintain stability under blasting operations. The tip dynamic response coefficient (DRC) of parallel cracks in a typical rock mass under combined dynamic and static loading ...

Fatigue crack growth in thin notched woven glass composites under tensile loading. Part II: modelling [PDF]
, 2011 Fatigue propagation of a through-the-thickness crack in thin woven glass laminates is difficult to model when using homogeneous material assumption. Crack growth depends on both the fatigue behaviour of the fibres and of the matrix, these two phenomena ...

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 ...

EFFECT OF SLANT CRACK ON WEAKENING MOTOR SHAFT STIFFNESS
Jixie qiangdu, 2019 Based on fracture mechanics theory,the calculation formula of shaft with oblique crack under six loads,including axial force,moment and torque etc. along the main coordinate axis,was deduced at arbitrary inclination angles.

Antiplane point load solution for a linear slot with rounded ends
Journal of the Mechanical Behavior of Materials, 2020 An exact linear elastic solution is derived for a pair of opposing point loads, which act in the middle of a straight slot having rounded ends. This problem is analogous to the mode III crack problem where two concentrated forces act in opposite ...

ZIP3D: An elastic and elastic-plastic finite-element analysis program for cracked bodies [PDF]
ZIP3D is an elastic and an elastic-plastic finite element program to analyze cracks in three dimensional solids. The program may also be used to analyze uncracked bodies or multi-body problems involving contacting surfaces.

Analytical approach to the determination of dynamic characteristics of a cracked beam [PDF]
, 2007 A wide spectrum of investigations devoted to the determination of natural frequencies and mode shapes of beams with an open crack are presented in the literature. However, as is well known, an open crack is a fairly crude model of a fatigue crack.

Lamb wave near field enhancements for surface breaking defects in plates [PDF]
, 2012 Near field surface wave ultrasonic enhancements have previously been used to detect surface breaking defects in thick samples using Rayleigh waves. Here, we present analogous surface wave enhancements for Lamb waves propagating in plates.
