Duplicate address detection (DAD) is an important component of the address resolution protocol (ARP) and the neighbor discovery protocol (NDP). DAD determines whether an IP address is in conflict with other nodes. In traditional DAD, the target address to be detected is broadcast through the network, which provides convenience for malicious nodes to attack. A malicious node can send a spoofing ...

An HPLC-DAD method for the quality control of wild and cultivated Ganoderma lucidum (Linhzhi) and related species samples was developed and validated. The quantitative determination of G. lucidum and its related species using 14 triterpene constituents, including nine ganoderma acids (compounds 4-12), four alcohols (compounds 13-16), and one sterol (ergosterol, 17) were reported. The standard c...

Of the alcohol-related risks faced by college students, it is arguable that none presents a greater public health hazard than driving after drinking (DAD). The present study examined the extent to which students' injunctive misperceptions toward DAD predicted the likelihood to engage in DAD and how this relation was mediated by self-approval of DAD. Participants were 2,848 college students (59....

This memo specifies SEcure Neighbor Discovery (SEND) Source Address Validation Improvement (SAVI), a mechanism to provide source address validation using the SEND protocol. The proposed mechanism complements ingress filtering techniques to provide a finer granularity on the control of IPv6 source addresses.

An automated, qualitative screening HPLC method for the identification of basic compounds in urine has been established. A 1-ml volume of urine was extracted by on-line extraction and separated on two coupled strong cation-exchange columns under isocratic conditions. The use of the photodiode-array detector (DAD, = 190370 nm) gave access to a library of > 2600 toxicologically relevant compounds...

BACKGROUND This study compares registry and non-registry approaches to linking 2006 Census of Population data for Manitoba and Ontario to hospital data from the Discharge Abstract Database (DAD). DATA AND METHODS Using a probabilistic linkage, the registry approach linked the census data to provincial health insurance registries, followed by a deterministic linkage to the DAD based on health ...

Guanylhydrazones are molecules with great pharmacological potential in various therapeutic areas, including antitumoral activity. Factorial design is an excellent tool in the optimization of a chromatographic method, because it is possible quickly change factors such as temperature, mobile phase composition, mobile phase pH, column length, among others to establish the optimal conditions of ana...

The abbreviations section includes a strange mixture of terms that are in everyday use and often bizarre entries (for instance, CRTAP [cartilage associated protein] and DAD [doctor assisted suicide]), which admittedly may represent commonly used terms in the authors’ local areas. There are duplications and ‘Americanisms’ (for instance, CBC [complete blood count] and FBC [full blood count]), whi...

It is increasingly recognized that good reliability practice requires giving attention to the specification of joint distributions for failure times. If the marginal distributions are known then the problem of selecting a marginal distribution is equivalent to that of selecting a copula. In the competing risk situation, identification of the copula alone is important, for together with competin...
