120-cell

In geometry, the 120-cell is the convex regular 4-polytope with Schläfli symbol {5,3,3}. It is also called a C₁₂₀, hecatonicosachoron, dodecacontachoron and hecatonicosahedroid.

The boundary of the 120-cell is composed of 120 dodecahedral cells with 4 meeting at each vertex.

It can be thought of as the 4-dimensional analog of the dodecahedron and has been called a dodecaplex (short for "dodecahedral complex"), hyperdodecahedron, polydodecahedron. Just as a dodecahedron can be built up as a model with 12 pentagons, 3 around each vertex, the dodecaplex can be built up from 120 dodecahedra, with 3 around each edge.

The Davis 120-cell, introduced by Davis (1985), is a compact 4-dimensional hyperbolic manifold obtained by identifying opposite faces of the 120-cell, whose universal cover gives the regular honeycomb {5,3,3,5} of 4-dimensional hyperbolic space.

Cell (セル) is a Japanese visual kei rock band, formed by Kon, from the band La'Mule and NightingeiL in May 2012.

Biography

Vocalist KON (ex.La'Mule), guitarists SIN and NAO (both ex. La'Mule), bassist YUKI came together and formed the band in April 2012. Composed with infinite styles and possibilities of the band, creating a new form, CELL launched had launched their activity.

Shortly after the band's formation, a series of One Man concerts had been held at the Ikebukuro EDGE. The band had released 3 maxi singles, 1 DVD single, and contributed to former X Japan guitarist hide's tribute album hide TRIBUTE -VISUAL STYLES II- covering the song "Hurry Go Round".

Since 2013, CELL has been boosted their activities internationally being invited as the special guest to one of Los Angeles's biggest Japanese Convention AX2013 and played the bands first U.S.A show. In 2014, Vocalist KON had appeared as a guest representing CELL at the LA VK Fest held in Downtown, Los Angeles, as well as holding a Livestream Q&A Session for fans in the States.

Spreadsheet

A spreadsheet is an interactive computer application for organization, analysis and storage of data in tabular form. Spreadsheets are developed as computerized simulations of paper accounting worksheets. The program operates on data represented as cells of an array, organized in rows and columns. Each cell of the array may contain either numeric or text data, or the results of formulas that automatically calculate and display a value based on the contents of other cells.

Spreadsheet users may adjust any stored value and observe the effects on calculated values. This makes the spreadsheet useful for "what-if" analysis since many cases can be rapidly investigated without manual recalculation. Modern spreadsheet software can have multiple interacting sheets, and can display data either as text and numerals, or in graphical form.

Besides performing basic arithmetic and mathematical functions, modern spreadsheets provide built-in functions for common financial and statistical operations. Such calculations as net present value or standard deviation can be applied to tabular data with a pre-programmed function in a formula. Spreadsheet programs also provide conditional expressions, functions to convert between text and numbers, and functions that operate on strings of text.
