CVT + SCT calculations on the rate of tunnelling at 20 K in the ring opening of cyclopropylcarbinyl radical, substituted with geminal methyl groups at a ring carbon (1b), have been performed. The calculations predict that, contrary to expectations based on the effect of mass on the rate of tunnelling, the geminal methyl substituents in 1b should make the rate of ring opening to 1,1-dimethyl-3-b...

This paper proposes an ensemble method for multilabel classification. The RAndom k-labELsets (RAKEL) algorithm constructs each member of the ensemble by considering a small random subset of labels and learning a single-label classifier for the prediction of each element in the powerset of this subset. In this way, the proposed algorithm aims to take into account label correlations using single-...

objective: in spite of introduction of novel drugs, obsessive-compulsive disorder (ocd) has still found no suitable treatment. on the other hand, high rates of co-morbidity of ocd with bipolar spectrum disorders are increasingly recognized. mood switching and development of rapid cycling with antidepressants are significant problems in these patients. from this viewpoint, introducing a non-anti...

a label-free electrochemical nucleic acid aptasensor for the detection of methamphetamine (ma) by the immobilization of thiolated self-assembled dna sequences on a gold nanoparticles-chitosan modified electrode is constructed. when ma was complexed specifically to the aptamer, the configuration of the nucleic acid aptamer switched to a locked structure and the interface of the biosensor changed...

In food sector, there is a huge demand for rapid, reliable, user & eco-friendly biosensors to analyse the quality and safety of food products. Biosensor based methodology depends upon the recognition of a specific antigens or receptors by corresponding antibodies, aptamers or high-affinity ligands. The first scientifically commercialised sensors were the electrochemical sensors used for the ana...

The generalized multiprotocol label switching (GMPLS) networks attain a hierarchical structure, and each layer maintains an independent protection mechanism, resulting in redundant protection. The common pool method provides a basic approach to solve the redundant protection problem. Although the common pool method is simple and robust, however it can fail in some cases. This work first shows t...

Status of This Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Abstract Multiprotocol Label Switching (MPLS), described in RFC 3031, is a method for forwarding packets that uses short, fixed-length values carried by packets, called labels, to determine packet next hops. A fundamental co...

Use of Node-ID based Resource Reservation Protocol (RSVP) Hello messages is implied in a number of cases, e.g., when data and control planes are separated, when TE links are unnumbered. Furthermore, when link level failure detection is performed by some means other than exchanging RSVP Hello messages, use of a Node-ID based Hello session is optimal for detecting signaling adjacency failure for ...

When setting up a Label Switched Path (LSP) in Generalized MPLS (GMPLS) and MPLS Traffic Engineering (MPLS-TE) networks, the completion of the signaling process does not necessarily mean that the cross-connection along the LSP has been programmed accordingly and in a timely manner. Meanwhile, the completion of the signaling process may be used by LSP users or applications that control their use...

Multi-Topology (MT) routing is supported in IP networks with the use of MT-aware IGPs. In order to provide MT routing within Multiprotocol Label Switching (MPLS) Label Distribution Protocol (LDP) networks, new extensions are required. This document describes the LDP protocol extensions required to support MT routing in an MPLS environment. Information about the current status of this document, ...
