The Cancer Research MinerĀ  is our most recent specialty search solution, available now at


Find research centers, news, clinical trials, discoveries, informatics, & more.

Due to the magnitude and impact of cancer-related topics, we are contemplating adding an exclusive section of miners for different types of cancers so researchers can build even more focused curated collections.

The figure below is a nature-inspired shape. It corresponds to a computer generated cluster pattern obtained via affine transformations that include reflection operations. Similar clusters resembling the progression of cancer can be generated in this way.

On Fractal Topography and Scale-Invariance


, , , ,

Closing a gap in the fractal geometry theory: Definition of fractal topography to essential understanding of scale-invariance.


One year old, but very relevant these days. Very important and enlightening research article.

A better understanding of scale-invariance by means of defining fractal topography opens the door to many practical applications. This was something loosely suggested in the literature, but not fully addressed. Great job!

A great tool for math history researchers and students in general.


A Tutorial on Polynomial Regression through Linear Algebra


, , , , , , ,

If you are a chemist, biodesigner, or a researcher working in other fields, eventually you may need to fit a paired data set to a polynomial regression model. You could use software to do that, or build your own solution. This tutorial is aimed at those interested in the latter. Access it now at


Three different methods for implementing polynomial regression are described. Teachers and students might benefit from the tutorial since the calculations can be done with a spreadsheet software like Excel, by writing a computer program, or with a programmable calculator.



One-to-Many (O2M) Tools

Some developers build form-based graphical user interfaces (GUIs) that give users the illusion of mapping the value of an input field to all other fields. Typical examples are conversion unit tools and other types of converters used in science and business oriented sites. This is frequently done by coding in the background M number of fields M number of times, with most fields hidden or dynamically coded. These M x M fields are then conditionally processed.

As M increases said strategy becomes very inefficient from both the coding and processing standpoint. Modifying these types of GUIs can be messy. For instance, to display a simple unit conversion tool with five conversion units requires the coding of 25 fields. To add an additional conversion unit requires the coding of 6 x 6 = 36 fields. Insane!

To overcome all those drawbacks, we have developed what we call a one-to-many fields mapping algorithm or O2M. The algorithm is quite simple and works as follows. Given a form with M unique text fields, randomly using one as an input field instructs the algorithm to treat the remaining ones as output fields. It does not matter which field is initially used or from where the data comes from (i.e., a user or database). Its value will be mapped to the remaining M – 1 fields. As a whole, an O2M GUI behaves as a many-to-many (M2M) solution. To grasp the concept, try one of our O2M tools at
