The National Academy of Sciences 155th Annual Meeting begins Saturday, April 28. Many events and scientific sessions will be webcast live. Recent flooding events highlight why flood-risk governance in the United States needs a major overhaul. They also suggest why the necessary refocus on shared responsibility will not be easy. Core Concept: Organoids have opened avenues into investigating numerous diseases. But how well do they mimic the real thing? They’re rudimentary versions of their real-life counterparts, but with continued cell-culture method improvements, researchers hope to create larger and more elaborate models.

The tattoos now in development carry real practical and medical import. But researchers agree that to gain widespread use the tattoos must also visually impress. Researchers estimate the risk of infectious disease transmission on board transcontinental airline flights. Researchers report early evidence of Maya animal management. Aquatic environments constrain mammals’ body size to a greater extent than terrestrial environments, according to a study. Bridget Scanlon discusses the use of global hydrologic models for studying changes in water storage worldwide.

The m rows are horizontal and the n columns are vertical. Each element of a matrix is often denoted by a variable with two subscripts.

For example, a2,1 represents the element at the second row and first column of a matrix A. Applications of matrices are found in most scientific fields. A major branch of numerical analysis is devoted to the development of efficient algorithms for matrix computations, a subject that is centuries old and is today an expanding area of research. Matrix decomposition methods simplify computations, both theoretically and practically. A matrix is a rectangular array of numbers or other mathematical objects for which operations such as addition and multiplication are defined.

The numbers, symbols or expressions in the matrix are called its entries or its elements. The horizontal and vertical lines of entries in a matrix are called rows and columns, respectively. The size of a matrix is defined by the number of rows and columns that it contains. Matrices which have a single row are called row vectors, and those which have a single column are called column vectors.

A matrix which has the same number of rows and columns is called a square matrix. A matrix with the same number of rows and columns, sometimes used to represent a linear transformation from a vector space to itself, such as reflection, rotation, or shearing. The specifics of symbolic matrix notation vary widely, with some prevailing trends. Alternative notations for that entry are A or Ai,j. In this case, the matrix itself is sometimes defined by that formula, within square brackets or double parentheses.
