we have investigated structure and electronic properties of au and si liner chains using the firstprinciplesplane wave pseudopotential method. the transport properties and conductance of these twoliner chains are studied using landauer approaches based on density functional theory (dft). weobtain density of states and band gap using kohn-sham and wannier functions as well as quantumconductivity...

In this paper, Kekule structures of benzenoid chains are considered. It has been shown that the coefficients of a B_n (x) Morgan-Voyce polynomial equal to the number of k-matchings (m(G,k)) of a path graph which has N=2n+1 points. Furtermore, two relations are obtained between regularly zig-zag nonbranched catacondensed benzenid chains and Morgan-Voyce polynomials and between regularly zig-zag ...

In the context of economic deglobalization and reconstruction global value chains, survival development manufacturing industry has encountered multiple difficulties. This paper will discuss how Chinese private enterprises in can build regional chains by effectively investing countries along "Belt Road" through OFDI, complete their own transformation as well enhance chain positions construction ...

This paper presents an approach on how to identify and design adaptable logistics chains configurations. Logistics chains are mostly influenced by changes in their business environment. A system’s adaptability is seen as one potential to effectively counteract these environmental changes. To consider the effects of adaptability on the whole supply chain, a framework for configuring adaptable lo...

International subcontracting relationships are often characterized by considerable power asymmetries. The actors in global value chain obtained different profits. Different governance dominant modes reflect different roles of countries and enterprises played in the global value chains and result in different industrial international competitiveness in the end Through a relation model of upstrea...

This paper addresses the problem of designing supply chains that are resilient to natural or human-induced extreme events. It focuses on the development of efficient restoration strategies that aid the supply chain in recovering from a disruption, thereby limiting the impact on its customers. The proposed restoration model takes into account possible disruptions to infrastructures, e.g., transp...

A literature review and gap analysis indentifies key limitations of industry best practice when modelling of supply chains. To address these limitations the paper reports on the conception and development of an integrated modelling methodology designed to underpin the analytical design of complex supply chains. The methodology is based upon a systematic deployment of EM, CLD, and SM techniques;...

This study aims at contributing to the analysis of the evolution of apparel industry in Brazil by answering the following questions: (a) Does global sourcing still explain the value upgrading process in the apparel production chains?; (b) Are there new sources of value upgrading to be considered?; (c) Is the dynamics of the apparel production pervaded by a phenomenon that is strongly related to...
