  • MATLAB
  • In MATLAB a vector is a matrix with either one row or one column. (pdx.edu)
  • MATLAB vectors are used in many situations, e.g., creating x-y plots, that do not fall under the rubric of linear algebra. (pdx.edu)
  • MATLAB still enforces the rules of linear algebra so paying attention to the details of vector creation and manipulation is always important. (pdx.edu)
  • retroviruses
  • In addition, VVL is funded by NIH for the generation of vesicular stomatitis viruses as vaccine vectors for West Nile virus and simian retroviruses in collaboration with the Tulane National Primate Research Center in Covington, LA. (lsu.edu)
  • Viral vectors, especially retroviruses, stably expressing marker genes such as GFP are widely used to permanently label cells to track them and their progeny, for example in xenotransplantation experiments, when cells infected in vitro are implanted into a host animal. (wikipedia.org)
  • Some viral vectors, for instance gamma-retroviruses, insert their genomes at a seemingly random location on one of the host chromosomes, which can disturb the function of cellular genes and lead to cancer. (wikipedia.org)
  • viral vector
  • Five classes of viral vector can be categorized in two principal groups, according to whether their genomes integrate into host cellular chromatin (lentiviruses and oncoretroviruses) or persist in the cell nucleus predominantly as extrachromosomal episomes (adenoviruses, adeno-associated viruses and herpes viruses). (news-medical.net)
  • In conclusion, there is still a tremendous amount of work to be done in viral vector research. (news-medical.net)
  • Low toxicity: The viral vector should have a minimal effect on the physiology of the cell it infects. (wikipedia.org)
  • This is detrimental to predictability and reproducibility of the work conducted using a viral vector and is avoided in their design. (wikipedia.org)
  • The cells can then be isolated easily as those that have not taken up the viral vector genes do not have antibiotic resistance and so cannot grow in a culture with antibiotics present. (wikipedia.org)
  • spatial
  • Grassmann's 1840 work Theorie der Ebbe und Flut (Theory of the Ebb and Flow) was the first system of spatial analysis similar to today's system and had ideas corresponding to the cross product, scalar product and vector differentiation. (wikipedia.org)
  • matrix
  • The matrix product of a column and a row vector gives the dyadic product of two vectors a and b, an example of the more general tensor product. (wikipedia.org)
  • Continuing with row vectors, matrix transformations further reconfiguring n-space can be applied to the right of previous outputs. (wikipedia.org)
  • The matrix transformations mount up to the left in this use of a column vector for input to matrix transformation. (wikipedia.org)
  • That is, the matrix that transforms the vector components must be the inverse of the matrix that transforms the basis vectors. (wikipedia.org)
  • one specified as a column matrix is known as a column vector. (wikipedia.org)
  • matrices
  • Refer to Pre-allocating memory for vectors and matrices for a discussion of the performance issues. (pdx.edu)
  • It is often used in copy operations and in the creation of vectors and matrices. (pdx.edu)
  • Transpose
  • Otherwise the transpose operator is applied to the value, 5, before the vector is created. (pdx.edu)
  • The technical construction uses the dual space associated with a vector space to develop the transpose of a linear map. (wikipedia.org)
  • viruses
  • Viral vectors are usually derived from parental wild type viruses whose viral genes (essential for replication and virulence) have been replaced with the heterologous genes intended for cell manipulation. (news-medical.net)
  • In vitro and clinical use of viral vectors is based on RNA and DNA viruses that differ in their genomic structures and host range. (news-medical.net)
  • Like all replication-incompetent vectors and viruses, viral particles can only be constructed if missing functions are superseded. (news-medical.net)
  • The two major classes of methods are those that use recombinant viruses (sometimes called biological nanoparticles or viral vectors) and those that use naked DNA or DNA complexes (non-viral methods). (wikipedia.org)
  • Safety: Although viral vectors are occasionally created from pathogenic viruses, they are modified in such a way as to minimize the risk of handling them. (wikipedia.org)
  • advantages
  • There are numerous ways to actually create a vector, each one having advantages in particular situations. (pdx.edu)
  • rather, each of the vectors has its own advantages, limitations and range of applications. (news-medical.net)
  • Hi netters, I would like to report the availability of a set of reporter gene vectors that have some distinct advantages over those currently in use for the purpose of analysis of eukaryotic promoters & enhancers. (bio.net)
  • trials
  • Furthermore, human trials have thus far used vectors that integrate into a relatively small percentage of cells within a target tissue. (news-medical.net)
