Small Surface Fatigue Crack Behaviors of Cr-Mo Steel AISI4137
CrystalsCosts are increasing due to the addition of alloying elements such as V, W, and Mo to prevent damage to Cr-Mo steel for fastening bolts, but field tests have shown that it is not an appropriate solution for improving physical properties through heat ...

Advanced Materials Interfaces, EarlyView.This study investigates the antifungal efficacy of ultrashort pulsed laser‐induced periodic surface structures (USP‐DLIP) on copper, brass, and steel surfaces. Using Aspergillus niger as a model, the research highlights a 99% reduction in spore viability on 9 µm structured copper surfaces due to enhanced copper ion release. Scanning electron microscopy

On Comparison of Some Ridge Parameters in Ridge Regression
Sri Lankan Journal of Applied Statistics, 2014 In this article, a new approach to obtain the ridge parameter introduces for the multiple linear regression model suffers from the problem of multicollinearity. Furthermore, we compare the proposed ridge parameter with the other well-known ridge-parameters through ridge estimators evaluated elsewhere in terms of mean squares error (MSE) criterion ...

, 2020 Constructing confidence intervals for the coefficients of high-dimensional sparse linear models remains a challenge, mainly because of the complicated limiting distributions of the widely used estimators, such as the lasso.

A thin rivulet or ridge subject to a uniform transverse\ud shear stress at its free surface due to an external airflow [PDF]
, 2012 We use the lubrication approximation to analyse three closely related problems involving a thin rivulet or ridge (i.e. a two-dimensional droplet) of fluid subject to a prescribed uniform transverse shear stress at its free surface due to an external ...

Advanced Materials Interfaces, EarlyView.Novel p‐type graphene/InAs quantum dot (QD)/n‐type GaAs mixed‐dimensional heterojunction structures are demonstrated for 1.3 µm light‐emitting diodes The p‐graphene serves as an ultrathin hole injection layer and the hybrid device shows 800 × stronger electroluminescence output powers than the reference LEDs without p‐graphene.

Chandra View of the Dynamically Young Cluster of Galaxies A1367 I. Small-Scale Structures
, 2002 The 40 ks \emph{Chandra} ACIS-S observation of A1367 provides new insights into small-scale structures and point sources in this dynamically young cluster. Here we concentrate on small-scale extended structures. A ridge-like structure around the center (`

The subsidence of aseismic ridges
Earth and Planetary Science Letters, 1977 All available Deep Sea Drilling Project results from aseismic ridges have been compiled. These results indicate that at least five major aseismic ridges — the Ninetyeast Ridge, the Rio Grande Rise, the Walvis Ridge, the Chagos-Laccadive Ridge and the southeast Mascarene Plateau — have formed close to sea level and have since subsided at rates ...
