A clever use of SciPy’s ndimage.generic_filter for n-dimensional image processing

by Juan Nunez-Iglesias in I Love Symposia!

This year I am privileged to be a mentor in the Google Summer of Code for the scikit-image project, as part of the Python Software Foundation organisation. Our student, Vighnesh Birodkar, recently came up with a clever use of SciPy’s ndimage.generic_filter that is certainly worth sharing widely.

Vighnesh is tasked with implementing region adjacency graphs and graph based methods for image segmentation. He initially wrote specific functions for 2D and 3D images, and I suggested that he should merge them: either with n-dimensional code, or, at the very least, by making 2D a special case of 3D. He chose the former, and produced extremely elegant code. Three nested for loops and a large number of neighbour computations were replaced by a function call and a simple loop. Read on to find out how.... Read more »

The Love Song of Philo T. Farnsworth

by Dr. Jekyll in Lunatic Laboratories

Philo Farnsworth, if the name sounds vaguely familiar than you might just be a Futurama watcher. If you don't watch and know who I'm talking about or even better are a fan then, "YAY!" and for those of you who don't know, don't sweat it you're not alone. One of the forgotten greats, Farnsworth should be a household name, namely because one of his biggest inventions is in practically every home.... Read more »

Power grid designs for the future

by Joerg Heber in All That Matters

Planning electrical grids in a steady environment is not overly difficult. A number of large power stations are connected to urban population centres, where much of the power is consumed. Typically, such power grids would look like meshes with  interconnected distribution points that make sure that if one power station fails, others can compensate . However, as electrical demand […]... Read more »

Synthetic Biology: Engineering Life To Examine It

by Jalees Rehman in Fragments of Truth

Two scientific papers that were published in the journal Nature in the year 2000 marked the beginning of engineering biological circuits in cells. The paper "Construction of a genetic toggle switch in Escherichia coli" by Timothy Gardner, Charles Cantor and James Collins created a genetic toggle switch by simultaneously introducing an artificial DNA plasmid into a bacterial cell. This DNA plasmid contained two promoters (DNA sequences which regulate the expression of genes) and two repressors (genes that encode for proteins which suppress the expression of genes) as well as a gene encoding for green fluorescent protein that served as a read-out for the system. The repressors used were sensitive to either selected chemicals or temperature. In one of the experiments, the system was turned ON by adding the chemical IPTG (a modified sugar) and nearly all the cells became green fluorescent within five to six hours. Upon raising the temperature to activate the temperature-sensitive repressor, the cells began losing their green fluorescence within an hour and returned to the OFF state. Many labs had used chemical or temperature switches to turn gene expression on in the past, but this paper was the first to assemble multiple genes together and construct a switch which allowed switching cells back and forth between stable ON and OFF states.

How Does Your Facebook News Feed Affect You?

by Jalees Rehman in The Next Regeneration

Researchers at Facebook, Inc., the University of California, San Francisco (UCSF) and Cornell University teamed up to study whether manipulating the News Feeds of Facebook users would affect the emotional content of the users' status updates or postings. They recently published their findings in the PNAS paper "Experimental evidence of massive-scale emotional contagion through social networks" and suggest that they have found evidence of an "emotional contagion", i.e. the idea that emotions can spread via Facebook....
