9:32 AM | Flying a Drone Inside the World’s Largest Cave
https://vimeo.com/121736043 Ryan Deboodt, an aerial videographer, takes us on an otherworldly journey through Sơn Đoòng, the world’s largest cave, by both ground and air. Located near the Laos-Vietnam border, Sơn Đoòng cave was only discovered in 1991. It wasn’t until 2009 that it was officially deemed the world’s largest. If you’re wondering why it took that long, I suggest picking up a… Read more → The post Flying […]

5:00 AM | Infinite-dimensional $\ell^1$ minimization and function approximation from pointwise data
Infinite-dimensional $\ell^1$ minimization and function approximation from pointwise data by Ben Adcock We consider the problem of approximating a function from finitely-many pointwise samples using $\ell^1$ minimization techniques. In the first part of this paper, we introduce an infinite-dimensional approach to this problem. Three advantages of this approach are as follows. First, it provides interpolatory approximations in the absence of noise. Second, it does not require a priori bounds on […]

5:10 PM | Crochet for Science and the Science of Crocheted Coral
Crochet "life" in the form of coral reef art evolves just as real reefs do. Last week, Sophia Roosth, a historian and anthropologist of biology at Harvard University, gave a talk at Louisiana State University on an ethnographic study she has conducted with the creators of the Crochet Reef Project. Roosth's talk was a fascinating exposition of how collaborative science art projects like the Hyperbolic Crochet Reef adopt underlying principles of math, biology […]

4:34 PM | Annihilation of Extremely Halophilic Archaea in Hide Preservation Salt Using Alternating Electric Current
Salt contains extremely halophilic archaea and these microorganisms degrade leather quality. The aim of this study is to find an effective treatment system to kill these microorganisms in salt used in hide brine curing. Ten salt samples were obtained from Tuz Lake, Turkey, and the total cell counts of extremely halophilic archaea, proteolytic and lipolytic extremely halophilic archaea were determined. Two sets of experiments were designed to detect the inactivation impact of alternating […]

5:00 AM | Single and multiple snapshot compressive beamforming
Single and multiple snapshot compressive beamforming by Peter Gerstoft, Angeliki Xenaki, Christoph F. Mecklenbräuker For a sound field observed on a sensor array, compressive sensing (CS) reconstructs the direction-of-arrivals (DOAs) of multiple sources using a sparsity constraint. The DOA estimation is posed as an underdetermined problem expressing the acoustic pressure at each sensor as a phase-lagged superposition of source amplitudes at all hypothetical DOAs. Regularizing with an […]

10:25 PM | Thesis: Spectral classification using convolutional neural networks, Pavel Hála - implementation -
I love the approach !The following is "just" an MS Thesis but I simply found it fascinating for two reasons: Even though the author knows about astrophysics, you can read the thesis and think that he could be foreign to the field. Second, since CNNs are doing well on images,  Pavel does what people have been doing with voice, convert spectra into images. From the thesis:I was inspired by the way CRT monitors rasterize image on the shadow mask. The output matrices of intensities were […]
