Superconducting String Texture

open access: yes, 1999
We present a detailed analytical and numerical study of a novel type of static, superconducting, classically stable string texture in a renormalizable topologically trivial massive U(1) gauge model with one charged and one neutral scalar.

Visual Aftereffect Of Texture Density Contingent On Color Of Frame [PDF]

open access: yes, 1996
An aftereffect of perceived texture density contingent on the color of a surrounding region is reported. In a series of experiments, participants were adapted, with fixation, to stimuli in which the relative density of two achromatic texture regions was ...

The Impact of High‐Productivity Processing on the Fatigue Failure of an Additive Manufactured Superalloy HAYNES 282

open access: yesAdvanced Engineering Materials, EarlyView.
The low cycle fatigue life of additive manufactured HAYNES® 282® superalloy was investigated for conventional and high‐productivity processing: samples of the former lasted 1400–1700 cycles, while samples of the latter failed at ~ 1200 cycles, at 760 °C and 1% strain.

Optimal design of high‐performance rare‐earth‐free wrought magnesium alloys using machine learning

open access: yesMaterials Genome Engineering Advances
In this study, a small dataset of 370 datapoints of Mg alloys are selected for machine learning (ML), in which each datapoint includes five rare‐earth‐free alloying elements (Ca, Zn, Al, Mn and Sn), three extrusion parameters (extrusion speed ...

Effects of heat treatment technology on microstructures and properties of 30Cr15NiMo martensitic stainless steel

open access: yesCailiao gongcheng
As an effective approach for improving the match of strength and ductility of martensitic stainless steel, the processing of quenching and partitioning (Q&P) is seldom implemented in industrial practice of commercial steels due to two factors: the one is

Uniform Spheres of α-NaYF4:RE3+ (RE=Eu, Tb, Ce, Er, and Tm): Template-Free Synthesis, Multi-Color Photoluminescence, and Their Application in Cellular Imaging

open access: yesCrystals, 2020
Uniformly dispersed luminescent probes with a high brightness and high resolution are desired in bio imaging fields. Here, ~100 nm sized and well-dispersed spheres of RE3+ doped α-NaYF4 (rare earth (RE) = Eu, Tb, Ce, Er, and Tm) have been facile ...

Achieving outstanding heat-resistant properties in Mg alloy via constructing stable solute-network

open access: yesMaterials Research Letters, 2023
A new Mg–Sm–Ce–Mn-based alloying system with a large miscibility gap was uncovered, and multi-solute co-segregations at high-angular grain boundaries (HAGBs), dislocations and low-angular grain boundaries (LAGBs) are obtained after the proper extrusion ...

Perceptual-based textures for scene labeling: a bottom-up and a top-down approach [PDF]

open access: yes, 2010
Due to the semantic gap, the automatic interpretation of digital images is a very challenging task. Both the segmentation and classification are intricate because of the high variation of the data. Therefore, the application of appropriate features is of

Duplex Stainless Steel Laser‐Surface Textured: Stability in Brine Solution

open access: yesAdvanced Engineering Materials, EarlyView.
Controlled laser‐surface treatment (LST) of duplex DSS2205 steel is performed to increase its stability in brine solution under cyclic electrochemical assays. The superior protection with respect to flat and smooth panels is attributed to the presence of FeCr2O4 as the main protective oxide layer in the LST surface, after corrosion tests. The stability
