With the complex and changeable environment, demand yield in perishable products supply chain are usually uncertain. This paper studies a joint contract that combines revenue sharing with quantity discount to coordinate under uncertainty, which consists of one manufacturer retailer. The retailer pays down payment at beginning, gives shares proportion profit from last. To make sure both members ...

Blockchain, smart contracts, and related concepts have emerged in recent years as a promising technology for cryptocurrency, NFTs, other areas. However, there are still many security issues that must be addressed these technologies evolve. This paper reviews some of the leading social engineering attacks on well several vulnerabilities which result from insecure code development. A contract tes...

The first neutral 0D and 1D heterometallic assemblies based on orbitally degenerate heptacyanidorhenate(IV) were prepared structurally characterized. An analysis of the magnetic data polycrystalline samples showed that both compounds display slow magnetization relaxation at temperatures below 5 K. very low temperature measurements single crystals demonstrate for compound {[Mn(SB2+)Re(CN)7]·7H2O...

This paper introduces the supply chain networks integration and discusses the interest of synchronization within them. The evaluation of the causes of uncertainties within the supply chain networks is considered. The structure of a threeechelon supply chain is envisaged and the modeling of this structure is carried out. It is shown that the supply chain network can be exposed to both external a...

Problem statement: In today’s manufacturing world, globalization policies and rejuvenation have created a more intensive competition amongst manufacturers. On the other hand, manufacturers have turned to the option of adopting innovative technologies, process re-engineering and strategies such as efficient supply chain management to achieve a sustainable competitive advantage. Effective supply ...

The oxygen deficient CuOx planes of the high-Tc superconductors REBa2Cu3O6+x (RE denotes a rare-earth atom or yttrium) are studied. Starting from the Emery model for the Cu-O chain fragments, an extended ASYNNNI model is proposed to describe the statistical mechanics of the CuOx planes. The model is analysed by using Monte Carlo techniques, computing especially the charge transfer to the CuO2 p...

This paper proposes a domain-oriented software process re-engineering method that allows for e cient software process modeling and cuts overall software development cost. This is achieved by use of a software synthesis shell that supports the development of program generators from input speci cation syntax and rewrite rules. Application of the proposed method to the development of a large scale...

Cortical activity in vivo is characterized by asynchronous irregular spiking. Additionally, precise spike synchronization is observed with respect to the experimental protocol. Attempting to model this behavior, theoretical studies have focused on two extreme cases: random and feed-forward networks (syn(re chains). Here, we combine both descriptions by successively converting an isolated syn(re...
