Topic: Cell mathematics


  
  Station Information - Cell (mathematics)
A cell is a three-dimensional object that is part of a higher-dimensional object, such as a polychoron.
A cell is related to higher-dimensional objects in the way that a face, or two-dimensional polygon, is related to higher-dimensional objects.
For example, a cell is to a 4-dimensional polytope, or polychoron, what a face is to a 3-dimensional polytope, or polyhedron.

 24-cell - Wikipedia, the free encyclopedia
The boundary of the 24-cell is composed of 24 octahedral cells with six meeting at each vertex.
Two of the octahedral cells, the nearest and farther from the viewer along the W-axis, project onto an octahedron whose vertices lie at the center of the cuboctahedron's square faces.
Surrounding this central octahedron lie the projections of 16 other cells, having 8 pairs that each project to one of the 8 volumes lying between a triangular face of the central octahedron and the closest triangular face of the cuboctahedron.

 Biological cell: Definition and Links by Encyclopedian.com - All about Biological cell
Membranes, which separate the cell form its environment, work as a filter, and act as a communication relay with the outside.
Organisms vary from single cells which survive individually, through colonial forms with multiple similar cells living together, to multicellular forms in which cells are specialized and do not generally survive if separated.
The plasma membrane (a phospholipid bilayer) separates the interior of the cell from its environment and serves as a filter and communications beacon.

 In Silico Virtual Experiments
This is precisely the aim of the Silicon Cell Consortium Amsterdam, a cooperation of the Institute for Molecular Biological Sciences (IMBS) of the Vrije Universiteit in Amsterdam, the Swammerdam Institute for Life Sciences (SILS) and the Section Computational Science (SCS) of the University of Amsterdam, and CWI.
Mathematically speaking this research adds to a continuum-discrete hybrid model where discrete, moving and deformable objects, in which biochemical reactions take place, exchange species with the surrounding environment modelled as a continuum.
The dynamic heterogeneity of the living cell and the flexibility of the simplification techniques imply that the degree and type of simplification will vary in space and time, thus placing further constraints on the integration.

Cell population processes can be modelled as differential equations, difference equations or functional equations in population state spaces.
The transit of proliferating cells to quiescence or the recruitment of quiescent cells to cycling can be modelled as dynamic processes which effect the stabilization of the cell population.
Chemotherapy typically effects only proliferating cells and thus the recruitment of quiescent cells to cycling during therapy is of essential importance in treatment.

 Colorful Mathematics: Part IV
When you place a cell phone call, the phone must send out an electronic signal which carries a digitalized version of your speech (mathematics comes into play here through the use of error correction and data compression).
Over a period of time, as often happens in applied problems, relatively simple ways used to deal with constructing a mathematical model for the cell phone situation have been replaced by more complex approaches that are more realistic.
When a cell phone user wishes to make a call, a frequency (or channel) must be used to carry the call.

 News Release - An intelligent combination of mathematics and cell biology could spell the death to brain tumours
For this to occur, cells take part in a cycle of activity, in which they first produce new copies of the genetic information, then check that the copies have no errors, before finally splitting the cell into two.
But if the therapy is given when cells are in the repair phase of their cycle, they will simply sort out the damage and carry on growing.
The new mathematical model is enabling the team to calculate the best time intervals to leave between doses of radiation, so that the maximum number of cells are caught at a time when they can't repair the damage.

The importance of mathematical models for these disciplines lies not only in the possibility they offer to obtain numerical answers, but also in the depth of understanding that their qualitative study has for structuring further biological research.
The goal of the school was to bring young researchers from biological disciplines and from the several mathematical specialties together, describing a wide range of applications and methods and fostering an atmosphere of dialogue and exchange of problems and solutions.
The mathematical concept of coalescence was expounded and several aspects of the theory of branching processes were presented in detail.

Dimension (from Latin measured out) is, in essence, the number of degrees of freedom available for movement in a space.
In mathematics, there are three related meanings of the term polyhedron: in the traditional meaning it is a 3-dimensional polytope, and in a newer meaning that exists alongside the older one it is a bounded or unbounded generalization of a polytope of any dimension.

 Voronoi Cell Problem
Suppose S is a satured packing of the plane by unit circles, and V is the partitioning of the plane into Voronoi Cells about the centers of the circles.
By the construction methods of Voronoi Cells, and the fact that the packing of the plane is saturated, all of the conditions of Lemma 1 are met.
Since 11 has been shown to be both an upper and lower bound on the number of circles which may situated about a central circle in a saturated packing such that each circle contributes a side to the Voronoi Cell about the central circle, the answer to the Question is 11.

 NYU team develops enhanced algorithm for detecting changes in cancer genomes
The algorithm, published in the latest issue of the Proceedings of the National Academy of Sciences (PNAS), can also be applied to the multiple biomedical technologies (e.g., different kinds of micro-arrays) used to analyze cancer patients' genomes.
Its application reveals several excess as well as missing copies of DNA segments associated with various forms of cancer and ultimately, points to locations of both oncogenes and tumor suppressor genes.
An earlier version of the algorithm as well as several other competing algorithms were capable of dealing with only cancer data or only polymorphism data and were unable to separate variations in cancerous and non-cancerous genes in a single framework.

 Study shows how consensus is attained in a noisy world
The Northwestern study also clarifies how social norms might quickly be adopted and remain ingrained within society and how unicellular organisms might organize into multi-cellular structures.
The researchers show that a simple majority rule approach, in which each unit -- a person or a cell -- adopts the state of the majority of its neighbors within an intricate communication network, can efficiently lead to global organization.
The model is adaptable and robust -- a real-world system capable of responding to external conditions.
