Mathematical models have been used in many areas of supply chain management. In this paper, we present a mixed-integer non-linear programing (MINLP) model to solve a multi-period, closed-loop supply chains (CLSCs) with two echelons consist of producers and customers. In order to satisfy the demands, the producers are be able to order for materials in the beginning of each period for one or more...

Virus mutants isolated from persistent infections of vesicular stomatitis virus in BHK-21 cells were much less susceptible to interference mediated by the defective interfering particle used to establish the persistent infection. This mutational change occurred as early as 34 days in the persistent infection and continued for over 5 years. The earliest variants showed no oligonucleotide map cha...

Dieser Text betrachtet die weitere Entwicklung des Internet unter dem Fokus der Trusted Computing Group (TCG) Architektur und ihrer Anwendung für das Digital Restrictions Management (DRM). Er zeigt die Probleme auf, die entstehen, wenn man die Entschlüsselung von Daten an Systemzustände koppelt. Er schließt mit grundlegenden Einwänden gegen DRM.

The Messenger 152 – June 2013 sky-emission fringes and cannot be used for correcting the fringe patterns. There­ fore, fringes are not removed by the standard data­processing techniques (bias subtraction, bad pixel masking, and flat-fielding). Fringe removal requires an extra step, where a description of the fringe pattern is scaled and subtracted from each image. This has traditionally been a ...

Leishmania donovani promastigotes survive inside macrophage phagosomes by inhibiting phagosomal maturation. The main surface glycoconjugate on promastigotes, lipophosphoglycan (LPG), is crucial for survival and mediates the formation of a protective shell of F-actin around the phagosome. Previous studies have demonstrated that this effect involves inhibition of protein kinase C alpha. The prese...

Packaging of the human immunodeficiency virus type 1 Vif protein into virus particles is mediated through an interaction with viral genomic RNA and results in the association of Vif with the nucleoprotein complex. Despite the specificity of this process, calculations of the amount of Vif packaged have produced vastly different results. Here, we compared the efficiency of packaging of Vif into v...

Therefore, in situations of hypothyroidism, especially the congenital form of the disease, it is possible for auditory damage of endocochlear, retrocochlear origin,...

Arbuscular mycorrhizal (AM) fungi are capable of exploiting organic nitrogen sources, but the molecular mechanisms that control such an uptake are still unknown. Polymerase chain reaction-based approaches, bioinformatic tools, and a heterologous expression system have been used to characterize a sequence coding for an amino acid permease (GmosAAP1) from the AM fungus Glomus mosseae. The GmosAAP...

Abstract Fabric defect detection is anomaly detection, which widely studied in the textile industry. Like most tasks, there are some problems hindering results, such as class imbalance, defective sample scarcity, and feature selection. This paper proposes a method applying depthwise separable convolution autoencoder on dimensionality reduction one-class classifier support vector data descriptio...

to explore the possibility of using graphene based biosensor, adsorption of hydrogen peroxide on graphene has been investigated using density functional theory. the electronic properties of defect free and defective graphene in the presence of different number of hydrogen peroxide have been studied. the graphene with the most stable configuration defect named as sw defect is considered. the hig...
