Social and cultural considerations for the restoration of ‘lost’ tree species: The fall and rise of elm

open access: yesPeople and Nature, EarlyView.
Abstract Attempts to address biodiversity loss have led to ecosystem and species restoration efforts. Tree species restoration is particularly relevant because of increasing threats from pests and pathogens. However, there are different notions of ‘loss’, as well as sociocultural considerations, including social acceptability, which are often neglected

Proposing a New Approach for Security of Sending e-Cash Based on Blind Signature and Asymmetric Encryption Algorithms

open access: yesتحقیقات بازار یابی نوین, 2011
In e-Cash, signer must sign a value without seeing it's content directly. Traditional RSA based approaches encounter a fundamental problem named Chosen Text Attack. The main aim of this research is to propose an approach to overcome such attack. Although

Twin‐Wire In Situ Additive Manufacturing of NiTiNb Eutectic Alloys: Eliminating Unmelted Nb Particles and Tailored Superelasticity

open access: yesRare Metals, EarlyView.
ABSTRACT A major challenge in fabricating eutectic NiTiNb alloys is the incomplete melting of Nb due to its much higher melting point than the NiTi matrix. In this work, a novel electron‐beam freeform additive manufacturing strategy is developed to eliminate unmelted Nb particles and achieve a fully eutectic structure through independent dual‐wire ...

Dual‐Stage Heat Treatment for Enhanced Hydrogen Storage Properties of Mg−Ni−Y Alloys

open access: yesRare Metals, EarlyView.
ABSTRACT Mg−Ni−Y alloy is considered to be one of the most promising hydrogen storage materials, but its high dehydrogenation energy barrier hinders its practical application. A dual‐stage heat treatment (490°C × 4 h + 550°C × 4 h) is applied to optimize the microstructure and hydrogen storage performance of a vacuum‐melted Mg94Ni3Y3 alloy.

Thermodynamic Modeling of Sn–C and Fe–Sn–C Systems for the Tramp Elements Control in Steel Production

open access: yessteel research international, EarlyView.
A CALculation of PHAse Diagrams thermodynamic modeling for Fe–Sn–C system is carried out. The model and the developed database can be used to calculate phase diagrams and thermodynamic properties of this system over wide temperature/composition range, and a part of a larger thermodynamic database for steel and alloy system, and effectively used to ...

Accelerating m‐Invariance for Continuous Big Data Publishing

open access: yesIEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
To prevent personal information leakage from the collection and publication of big data, anonymization techniques that protect privacy while preserving data utility are essential. In particular, m‐invariance provides privacy protection for dynamic datasets that are continuously published as records are updated.

(t, n) Threshold d-Level Quantum Secret Sharing

open access: yesScientific Reports, 2017
Most of Quantum Secret Sharing(QSS) are (n, n) threshold 2-level schemes, in which the 2-level secret cannot be reconstructed until all n shares are collected.
