1:05 PM | Map Monday: Global Pesticide Scorecard Launched
The prevalence of pesticides may seem like something of a bygone era, one marked by Silent Spring and the Bhopal Disaster, but the grim reality is that they are unfortunately very much around.... -- Read more on ScientificAmerican.com

5:00 AM | On the Effective Measure of Dimension in the Analysis Cosparse Model
On the Effective Measure of Dimension in the Analysis Cosparse Model by Raja Giryes, Yaniv Plan, Roman Vershynin Many applications have benefited remarkably from low-dimensional models in the recent decade. The fact that many signals, though high dimensional, are intrinsically low dimensional has given the possibility to recover them stably from a relatively small number of their measurements. For example, in compressed sensing with the standard (synthesis) sparsity prior and in matrix […]

5:00 AM | Thesis: Approximate Message Passing Algorithms for Generalized Bilinear Inference, Jason Parker
Here is a new thesis: Approximate Message Passing Algorithms for Generalized Bilinear Inference by Jason Parker Recent developments in compressive sensing (CS) combined with increasing demands for effective high-dimensional inference techniques across a variety of disciplines have motivated extensive research into algorithms exploiting various notions of parsimony, including sparsity and low-rank constraints. In this dissertation, we extend the generalized approximate message passing (GAMP) […]

4:09 PM | The Butcher’s Tongue Illusion (from the chip-crunch manipulator)
Charles Spence (who was awarded an Ig Nobel Prize for earlier work, and who is pictured here) and his colleagues have demonstrated the “butcher’s tongue illusion”. Nicola Twilley, writing in Elements, conveys some of the new study’s flavor: The tongue in the title of Oxford University’s Crossmodal Research Laboratory’s new paper, “The Butcher’s Tongue Illusion,” does not […]

3:26 PM | A denture-friction scientist analyses the banana-skin paper
Maria Pettersson, a friction scientist at the Ångström Laboratory at Uppsala University, who is professionally focusing on dentures these days, discusses the Ig Nobel physics prize-winning study that measured the slipperiness of a banana peel. You can listen to the discussion on Sverige Radio [P4]. The discussion is in Swedish. This action photo shows a moment […]

1:40 PM | What’s up Watson? Using IBM Watson’s QAAPI with Bluemix, NodeExpress – Part 1
In this post I take the famed IBM Watson through the paces (yes, that’s right!, this post is about  using the same  IBM  Watson which trounced 2 human Jeopardy titans in a classic duel in 2011).  IBM’s Watson (see  What is Watson?) is capable of understanding the nuances of the English language and heralds a […]

1:09 PM | “Inappropriate”: Old vs. young vs. differing senses of humor
This study documents a great lesson of some sort that was sought and perhaps learned: “Age-related differences in judgments of inappropriate behavior are related to humor style preferences,” Jennifer Tehan Stanley, Monika Lohani, Derek M. Isaacowitz, Psychology and Aging, Vol 29(3), Sep 2014, 528-541. (Thanks to investigator Erwn Kompanjie for bringing this to our attention.) The authors […]

8:23 PM | How Do You Get to Antarctica?…Study…Study…Study
The Earth’s polar regions are holy lands for environmental researchers. Relatively pristine and preserved by their remoteness and shielded from many of humanity’s atmospheric impacts, the Arctic and Antarctic are environmental samples as close to “unadulterated” as any on the planet. Peter DeCarlo, PhD, an environmental engineer and atmospheric chemist at Drexel, will make his … Continue reading →

2:58 PM | Measuring Water Solubility of Platinum Group Metal Containing Substances
The water solubility of 22 platinum group metal (pgm) containing substances was evaluated to provide useful data for regulatory compliance and to aid assessment of their environmental impact. The flask method from OECD Guideline 105 (1) for the testing of chemicals (water solubility) was used to test each material. For substances that could not be isolated as pure solids, a simplified water solubility test was carried out. The results provide reliable data on solubility previously unavailable […]

5:01 AM | The Grids of Nobel (Medial Temporal Lobe-rific)
This year's Nobel Prize in Physiology and Medicine went to John O'Keefe, May-Britt Moser, and Edvard I. Moser for their work on the neurophysiology of spatial navigation [1]. The prize was awarded "for their discoveries of cells that constitute a positioning system in the brain". Some commentators have referred to these discoveries as constituting an "inner GPS system", although this description is technically and conceptually incorrect (as I will soon highlight). As a PhD student with an […]

3:30 PM | RQS (Read Quality-score Sparsifier): Traversing the k-mer Landscape of NGS Read Datasets for Quality Score Sparsification - implementation -
When you have entire fields that have been dedicated to compressing a certain type of data (image, videos), you generally rely on that knowledge to be optimal in your compression algorithms. But what happens when you have a Big Data problem and yet you really do not have the years of experience that built up in, say, image processing. Compressive Sensing suddenly becomes an attractive solution.   Traversing the k-mer Landscape of NGS Read Datasets for Quality Score Sparsification by Y. […]
