E-mail servers

Hacktivists Hacktivism refers to politically motivated attacks on publicly accessible Web pages or e-mail servers. These groups and individuals overload e-mail servers and hack into Web sites to send a political message. 

The architecture of Linux is based on Unix, the OS used in mainframes and other high-end computers, and it is extremely powerful and stable. Linux also is commonly used as a Web server or e-mail server on the Internet, and can function as either a network operating system or a desktop operating system, just as Windows NT can. 

Simple Mail Transport Protocol (SMTP) SMTP is used to send mail from a client to an e-mail server. SMTP servers do not store mail for users to pick up they simply send the mail out, and another server (such as a POP3 server) is used to store incoming mail.

The earliest computer network communications application, e-mail, is sfiU the largest and most successful network application. One accesses e-mail services through an e-mail client. The client can be a stand-alone program, such as Outlook Express or Eudora, or it can be browser based, using Internet Explorer or Foxfire. The e-mail server can be a proprietary system such as Lotus Notes or one of the...

Chemical Physics Preprint Database. This database [81] is a fully automated electronic archive and distribution server intended to provide a means for rapid and efficient preprint distribution within the international theoretical chemical physics community. A preprint is a copy of a paper that has been submitted for publication. This database has been designed to be a useful and freely available tool for education and research. It allows investigators to submit and retrieve electronic copies of preprints via the Internet. Access for retrieval and listing of papers in the database is possible through WWW servers, anonymous ftp, or e-mail. Currently research papers are submitted to the databases via e-mail. This project is a joint effort by the Department of Chemistry at Brown University and the Theoretical Chemistry and Molecular Physics Group at the Los Alamos National Laboratory. The homepage of Chemical Physics Preprint Database is http // www.chem.brown.edu/chem-ph.html. (For a more... 

Think twice before you send confidential, private, or other sensitive material in an e-mail message. E-mail messages can be intercepted. The information may reach people other than those you intend. Unless you are confident that the server is secure, you may not want to include information about yourself (Social Security number, credit card number, and so on) or your company s secrets (strategic plans for the future, account numbers, and so on). In fact, your company may have regulations about what can and cannot be sent over e-mail or the Internet. Find out and follow your company s guidelines. 

Another method is to complete an online-based resume form while visiting an employer s website or a career-related site. In order to keep incoming resumes consistent in terms of formatting, many websites designed for recruiting insist that all electronic resumes be created using a predefined template, or provide a detailed form that requests all pertinent resume information. The website then formats the information automatically to meet the employer s requirements. This information is kept on the company s server and you won t have a file to submit via e-mail.

The KMS is the component of Microsoft Exchange that allows the archiving and retrieval of keys used to encrypt e-mail. Both Exchange Servers 5.5 and 2000 integrate with a Windows 2000 CA for the issuance of x.509v3-compliant digital certificates.

Analysis (PSA) server of BMERC predicts secondary structures and folding classes from a query sequence. On the PSA home page at http //bmerc-www.bu.edu/psa/ index.html, select Submit a sequence analysis request to submit the query sequence and your e-mail address. The returned results include (a) probability distribution plots (conventional X/Y and contour plots) for strand, turn, and helix and (b) a list of structure probabilities for loop, helix, turn, and strand for every amino acid residues. 

The method of Rost and Sander (Rost and Sander, 1993), which combines neural networks with multiple sequence alignments known as PHD, is available from the PredictProtein (Rost, 1996) server of Columbia University (http //cubic.bioc. columbia.edu/predictprotein/). This Web site offers the comprehensive protein sequence analysis and structure prediction (Figure 12.8). For the secondary structure prediction, choose Submit a protein sequence for prediction to open the submission form. Enter e-mail address, paste the sequence, choose options, and then click the... 

The prediction of the secondary structures can be made by the structure similarity search of PDB collection at the site. Several servers provide such prediction method. The Jpred, which aligns the query sequence against PDB library, can be accessed at http //jura.ebi.ac.uk 8888/index.html. To predict the secondary structures, however, check Bypass the current Brookhaven Protein Database box and then click Run Secondary Structure Prediction on the home page of Jped to open the query page (Figure 12.10). Upload the sequence file via browser or paste the query sequence into the sequence box. Enter your e-mail address (optional) and click the Run Secondary Structure Prediction button. The results with the consensus structures are returned either online (linked file) or via e-mail (if e-mail address is entered). 

Figure 12.9. Protein structure prediction with PHD. The amino acid sequence of chicken lysozyme precursor (147 amino acids) is submitted to PredictProtein server for PHD structure predictions. The returned e-mail reports protein class based on secondary structures, predicted secondary structure composition (%H, %E, and %L), residue composition, data interpretation, and predicted data in two levels (brief and normal of which the normal is shown). Search for the database can be performed by making choice(s) from the list(s) of pop-up box(es).

The 3D-PSSM (Kelley et ah, 2000) server at http //www.bmm.icnet.uk/ 3dpssm/ offers online protein fold recognition. On the submission form, enter your e-mail address and a one-line description of the query protein, then paste the query sequence into the sequence box and click the Submit button. The query sequence is used to search the Fold library for homologues. You will be informed of the URL where the result is located for 4 days. The output includes a summary table (hits with statistics models that can be viewed with RasMol classifications and links) and fold recognition by 3D-PSSM with a printout as exemplified in Figure 12.13. The alignment displays consensus sequence, secondary structures (C for coil, E for extended, and H for helix), and core score (0 for exterior to 9 for interior core). 

E-mail and efficient communication with colleagues, sharing of files and work group activities. Server for common software. Use of mobile phones both for internal communications and for reporting in when off site. Teleconferencing facility. 

Depending on the publisher, authors may be asked to e-mail the prepared manuscript to the editor, to upload it via an FTP server, or to upload files through the publisher s Web browser to a secure Web site using HTTP protocol. It is extremely important to submit manuscripts in the method designated for that particular journal because submission mechanisms may vary, even within one publisher s journals. If the journal requires online manuscript submission, submit all files to that Web site. Similarly, if the journal uses FTP or e-mail, follow the instructions carefully and send all manuscript components via the same route, unless indicated otherwise. 

The other server is an FFF literature database at Rohm Haas http //www.ro-hmhaas.com/fff/ which is updated frequently. It is possible to get e-mail notice on database updates. Furthermore, it is planned to install an FFF user discussion forum on this web site.
