Multi-level contrastive learning for exploring graphs with higher-order dependencies in sequential data

open access: yesComplex & Intelligent Systems
Graph embedding, which maps nodes into a low-dimensional space while preserving their proximities based on graph topology, has gained significant attention. Traditional methods often assume the Markov property, thus overlooking higher-order dependencies.

A comprehensive multilevel model meta-analysis of self-concept interventions

open access: yes, 2006
The efficacy of self-concept interventions has previously been examined through traditional meta-analytic methods, and a host of moderators of intervention outcomes have been identified (O’Mara, Marsh, & Craven, 2004; Haney & Durlak, 1998; Hattie, 1992).

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

open access: yesAdvanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

open access: yesAdvanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Reversible watermarking scheme with image-independent embedding capacity [PDF]

open access: yes
Permanent distortion is one of the main drawbacks of all the irreversible watermarking schemes. Attempts to recover the original signal after the signal passing the authentication process are being made starting just a few years ago. Some common problems,

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

open access: yesAdvanced Engineering Materials, EarlyView.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Support for a reciprocal effects model of self-concept and academic achievement through a contrast of multidimensional and unidimensional approaches

open access: yes, 2006
There is a longstanding debate in the self-concept literature surrounding the causal ordering of self-concept and academic achievement. Some researchers have argued that self-esteem has no positive impact upon performance (Baumeister, Campbell, Krueger &
