Using different strategies to improve properties of the biodegradable Mg–4Li–4Zn alloy

open access: yesJournal of Materials Research and Technology, 2023
Recently, novel super light Mg–Li based alloys have attracted wide attention for potential use as biodegradable implants. However, like most of the biodegradable Mg alloys, Mg–Li alloys suffer from high degradation rate and poor mechanical properties ...

Semi-Supervised Learning for Neural Keyphrase Generation

open access: yes, 2018
We study the problem of generating keyphrases that summarize the key points for a given document. While sequence-to-sequence (seq2seq) models have achieved remarkable performance on this task (Meng et al., 2017), model training often relies on large ...

The power of expressed humility: Early stage investors' reaction to humble entrepreneurs

open access: yesStrategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary We examine how entrepreneur‐expressed humility affects early stage investors' willingness to fund new ventures. In pitching contexts where investors rely on relational cues and implicit prototypes of entrepreneurs, we theorize three distinct pathways through which expressed humility shapes funding decisions. First, building on

Research on multi-cylinder synchronous control system of multi-directional forging hydraulic press

open access: yesJournal of Physics: Conference Series, 2022
Abstract A master-slave synchronization control strategy based on RBF network adaptive sliding mode control is proposed to solve the problem of lack of effective control strategy and control accuracy in the process of synchronous motion of three horizontal cylinders of multi-directional die forging hydraulic press in VL ball cage forming

Board Attributes, Firm Performance, and the Moderating Role of National Culture: A Meta‐Analysis

open access: yesCorporate Governance: An International Review, EarlyView.
ABSTRACT Research Question/Issue The impact of board structures on firm performance remains a contentious governance topic with competing theoretical paradigms and inconclusive empirical support. Scholars propose that national culture could reconcile contradictory evidence; yet, argumentation is fragmented and direct tests are rare.

Rethinking network embeddedness in international business: A review and view in space and time

open access: yesInternational Journal of Management Reviews, EarlyView.
Abstract Conceptual and empirical contributions to network embeddedness have flourished in the last decades within the field of international business (IB). Scholars have used the concept to explain IB phenomena through the lens of business actors’ network relationships and positions in their networks.

Superplasticity of Fine-Grained Magnesium Alloy AZ31 Processed by Multi-Directional Forging

open access: yesMATERIALS TRANSACTIONS, 2007
Superplasticity was studied in a fine-grained magnesium alloy AZ31 processed by multidirectional forging (MDF) under decreasing temperature conditions. Tensile tests were carried out at temperatures from 393 K to 473 K and at various strain rates. Superplasticity appears even at a low temperature of 393 K with a stress exponent of around 5.6 and a ...
