In DNS zone delegation, the NS resource records of the delegated domain appear in both the parent and child zones, which complicates the domain name resolution procedure especially for server selection. In this paper, we investigate the recursive resolution mechanism for the delegated domain and the necessary operations. As there are no specifications for such resolution, we provide some recomm...

Multiprotocol Label Switching provides a virtual path capability between packet (label) switches to efficiently carry differentiated services across the Internet. Additionally, MPLS has been enhanced with the capability to precisely engineer traffic tunnels to avoid congestion and utilize all available bandwidth in an efficient manner. This paper provides an extensive resource, serving the moti...

The need to improve access to care and treatment for chronic hepatitis C virus (HCV) infection in resource-limited settings is receiving increasing attention. Key priorities for scaling up HCV treatment and care include reducing the cost of current and future treatment; simplifying the package of care; identifying opportunities to shift specific tasks to nonspecialists to overcome human resourc...

In the first part of this paper, we define two resource aware typing systems for the λμ-calculus based on non-idempotent intersection and union types. The nonidempotent approach provides very simple combinatorial arguments –based on decreasing measures of type derivations– to characterize head and strongly normalizing terms. Moreover, typability provides upper bounds for the lengths of the head...

introduction: human resources development is one of the most important components of any organization and detecting important factors influencing human resources management plays an essential role in the success of the firms. in this study, we investigated different factors influencing human resources productivity of shiraz university of medical sciences staff. method: the present research was ...

Isocyanides are important building blocks in organic synthesis; however, their synthesis is time and resource consuming often unpleasant due to smelly nature. Diversification of isocyanides can be accomplished by de novo or from already existing isocyanides. In this work, we report for the first-time isocyanide diversification based on nucleophilic aromatic substitution suitable precursor The m...

objective: silicon is an effective element in bone biomineralization; hence si-substituted hydroxyapatite can be a relevant bioceramic as bone materials substitution. materials and methods: stoichiometric hydroxyapatite (ha) and si-substituted hydroxyapatite (si-ha) with different contents of si substitution were synthesized successfully by a hydrothermal method using ca(no3)2, (nh4)3po4 or (n...

With the recent increase in the number of mammalian genomes being sequenced, large-scale genome scans for human-specific positive selection are now possible. Selection can be inferred through phylogenetic analysis by comparing the rates of silent and replacement substitution between related species. Maximum-likelihood (ML) analysis of codon substitution models can be used to identify genes with...

Modified nucleotides are resource-intensive alternatives to the four nucleotides that constitute the bulk of natural RNAs. Yet, even in cases where modifications are highly conserved, their functions are difficult to identify. One possible function might be to modulate the stability of RNA structures. To investigate this possibility for N 2-methylguanosine (m2G), which is present in a wide vari...
