Digital watermarking for relational databases emerged as a candidate solution to provide copyright protection, tamper detection, traitor tracing, maintaining integrity of relational data. Many watermarking techniques have been proposed in the literature to address these purposes. In this paper, we survey the current state-of-theart and we classify them… (More)
In order to determine the user’s trust is a growing concern for ensuring privacy and security in a cloud computing environment. In cloud, user’s data is stored in one or more remote server(s) which poses more security challenges for the system. One of the most important concerns is to protect user’s sensitive information from other users and hackers that… (More)
5'-Deoxy-5'-ureidoadenosine was designed and synthesized as a potent inhibitor of S-adenosylhomocysteine hydrolase (SAH), in which 5'-ureido group acted as multiple hydrogen bonding donor in binding with active site residues of SAH in the molecular modeling study.
Synthesis of fluorocyclopentenyl pyrimidine nucleosides 6-9 was enantiopurely accomplished employing oxidative rearrangement, RCM reaction and electrophilic fluorination starting from d-ribose. Cytosine analog 8 was found to exhibit significant anticancer activity in various human tumor cell lines.
Cloud-computing applications are fast replacing traditional mobile and desktop applications such as e-mail, document editing, or photo storage. Such applications may require ubiquitous network access that is not always available, e.g., in remote areas without infrastructure, but also in areas with infrastructure where the costs of access are too high for… (More)
We have established structure-activity relationships of novel truncated D-4'-thioadenosine derivatives from D-mannose as potent and selective A(3) adenosine receptor (AR) antagonists. At the human A(3) AR, most of N(6)-substituted analogues showed high potency and selectivity and acted as pure antagonists in a cyclic AMP functional assay. Among compounds… (More)
The rapid development in the field of communication has led to a very widespread dissemination of digital videos leading to their significant production and circulation. The advent of advanced technology has also led to a large scale illegal distribution and piracy of digital
As information hiding, the digital watermark techniques have been attracting more interests in both research and industrial fields. Relational database is widely used in many information systems, as a tool for storing and managing a data. Major issue to protect the copyright of relational data. In order to make watermarking information more intuitive and… (More)
With the tremendous growth of mobile devices, e.g, smartphones, tablets and PDAs in recent years, people are looking for more advanced platforms in order to use their computational applications (e.g., processing and storage) in a faster and more convenient way. In addition, mobile devices are capable of using cloud-based applications and the use of such… (More)
A novel route to functionalised bicyclo[2.2.2]octenones via pi 4s + pi 2s cycloaddition of cyclohexa-2,4-dienones with electron deficient 2 pi partners, and crystal structure of 1,7-dimethyl-5-hydroxy-5-chloromethyl-2-carboethoxy bicyclo[2.2.2]oct-7-ene-6-one, is reported.
