Super threading is a type of Multithreading computer architecture multithreading that enables different Thread computer programming thread s to be executed by a single CPU processor without truly executing them at the same time. ref http arstechnica.com articles paedia cpu hyperthreading.ars 3 Superthreading with a multithreaded processor ref This qualifies it as time sliced or temporal multithreading rather than simultaneous multithreading SMT . It is motivated by the observation that the processor s functional unit s are occasionally left idle while executing instructions from one thread due to long latency events. Super threading seeks to make use of the otherwise unused processor cycles by executing instructions from another thread until the previous thread is ready to resume execution. While this approach enables better use of the processor s resources, further improvements to resource utilization can be realized through SMT, which allows the execution of instructions from multiple threads at the same time. Consider a two way super threaded processor with four functional units. If thread one issues three instructions, one functional unit remains unused. In an SMT processor, it is possible for thread two to issue an instruction to the remaining unit, attaining full utilization of processor resources.

Conversation threading is a feature used by many email clients , bulletin board s, newsgroup s, or Internet forum s in which the software aids the user by visually grouping messages. Messages are usually grouped visually in a hierarchy by topic. A set of messages grouped in this way is called a topic thread or simply a thread . A discussion forum, e mail client or news client is said to have threaded topics if messages of the same topic are grouped hierarchically for easy reading. Moreover, threaded discussions typically allow users to reply to particular posting. As a result, there can be a hierarchy of discussions within the thread s topic. Various types of software may allow this hierarchy to be displayed in what s called Threaded Mode. The alternative being Linear Mode, which typically shows all of the posts in date order, regardless of who may have specifically replied to whom. Hierarchical threads Advantages The advantage of hierarchically threaded views is that they allow the reader to appreciate quickly the overall structure of a conversation specifically who is replying to whom. As such it is most useful in situation with extended conversations or debates, such as newsgroups indeed, for really complex debate, it quickly becomes impossible to follow the argument without some sort of hierarchical threading system in place. Another benefit is in the more subtle appreciation of community in hierarchically threaded systems. As responses have to be made to specific posts, they are also made to specific individuals. Threaded conversations therefore tend to focus the writer on the specific views and personality of the individual being responded to.

Explicit Multi Threading XMT is a computer science paradigm for building and programming parallel computers designed around the Parallel Random Access Machine PRAM parallel computational model. A more direct explanation of XMT starts with the rudimentary abstraction that made serial computing simple that any single instruction available for execution in a serial program executes immediately. A consequence of this abstraction is a step by step inductive explication of the instruction available next for execution. The rudimentary parallel abstraction behind XMT, dubbed Immediate Concurrent Execution ICE in harvtxt Vishkin 2011 , is that indefinitely many instructions available for concurrent execution execute immediately. A consequence of ICE is a step by step inductive explication of the instructions available next for concurrent execution. Moving beyond the serial von Neumann computer the only successful general purpose platform to date , the aspiration of XMT is that computer science will again be able to augment mathematical induction with a simple one line computing abstraction The random access machine RAM is an abstract machine model used in computer science to study algorithms and complexity for standard serial computing. The PRAM computational model is an abstract parallel machine model that had been introduced to similarly study parallel algorithms and complexity for parallel computing , when they were yet to be built.

The sequence hypothesis was first formally proposed in a review On Protein Synthesis by Francis Crick in 1958. It states that the sequence of bases in the genetic material DNA or RNA determines the sequence of amino acid s for which that segment of nucleic acid codes, and this amino acid sequence determines the three dimensional structure into which the protein folds. The three dimensional structure of a protein is required for a protein to be functional. This hypothesis then lays the essential link between information stored and inherited in nucleic acids to the chemical processes which enable life to exist. Or, as Crick put it in 1958 ..In its simplest form it the Sequence Hypothesis assumes that the specificity of a piece of nucleic acid is expressed solely by the sequence of its base pair bases , and that this sequence is a simple code for the amino acid sequence of a particular protein. This hypothesis appears to be rather widely held. Its virtue is that it unites several remarkable pairs of generalisations the central biochemical importance of proteins and the dominating role of genes , and in particular of their nucleic acid the linearity of protein molecules considered covalently and the genetic linearity within the functional gene the simplicity of the composition of protein molecules and the simplicity of the nucleic acids. This description is further amplified in the article and, in discussing how a protein folds up into its three dimensional structure, Crick suggested that the folding is simply a function of the order of the amino acids in the protein.

Peptide sequence or amino acid sequence is the order in which amino acid residues, connected by peptide bond s, lie in the chain in peptide s and protein s . The sequence is generally reported from the N terminal end containing free amino group to the C terminal end containing free carboxyl group . Peptide sequence is often called proteinsequence if it represents the primary structure of a protein . Sequence notation and applications Many peptide sequences have been in sequence database s. These databases may use various notations to describe the peptide sequence. The full names of the amino acids are rarely given instead, Amino acid Table of standard amino acid abbreviations and properties 3 letter or 1 letter abbreviations are usually recorded for conciseness. Several deductions can be made from the sequence itself. Long stretches of hydrophobic residues may indicate transmembrane helix transmembrane helices . These helices may indicate the peptide is a cell receptor . Certain residues indicate a beta sheet area. If full length proteinsequence is available, it is possible to estimate the isoelectric point of the protein. Methods for determining the peptide sequence include deduction from DNA sequence, Edman degradation , and mass spectrometry . Techniques in sequence analysis can be applied to learn more about the peptide. These techniques generally consist of comparing the sequence to other sequences from sequence databases. Other sequences may have already been studied and determined to be significant. Findings about these sequences may be applicable to the sequence under investigation.
