6:00 AM | Random Calibration for Accelerating MR-ARFI Guided Ultrasonic Focusing in Transcranial Therapy
  Random Calibration for Accelerating MR-ARFI Guided Ultrasonic Focusing in Transcranial Therapy Na Liu , Antoine Liutkus,  Jean-François Aubry , Laurent Marsac ,Mickael Tanter , Laurent DaudetAbstract : Transcranial focused ultrasound is a promising therapeutic modality. It consists in placing transducers around the skull and emitting shaped ultrasound waves that propagate through the skull and then concentrate on one particular location within the brain. However, the skull […]

2:00 PM | AA is Held to a Higher Standard.
I’m fond, over on twitter, of saying “AA works”. What I mean by that is too complex for the 140 character medium of twitter, but I’ve described it here many times. AA doesn’t “work” as a treatment for alcoholism the way, say, vaccines work for preventing illness or antibiotics work for treating infection. AA isn’t […]

6:00 AM | Frequency Selective Compressed Sensing - implementation -
Frequency Selective Compressed Sensing by Jacek Pierzchlewski, Thomas Arildsen In this paper the authors describe the problem of acquisition of interfered signals and formulate a filtering problem. A frequency-selective compressed sensing technique is proposed as a solution to this problem. Signal acquisition is critical in facilitating frequency-selective compressed sensing. The authors propose a filtering compressed sensing parameter, which allows to assess if a given acquisition process […]

4:30 PM | BlockPR: Fast Phase Retrieval for High-Dimensions - implementation -
Fast Phase Retrieval for High-Dimensions by Mark Iwen, Aditya Viswanathan, Yang Wang We develop a fast phase retrieval method which is near-linear time, making it computationally feasible for large dimensional signals. Both theoretical and experimental results demonstrate the method's speed, accuracy, and robustness. We then use this new phase retrieval method to help establish the first known sublinear-time compressive phase retrieval algorithm capable of recovering a given $s$-sparse vector […]

2:46 PM | Smelling bodies at the office (corporeal porosity)
As Dr. David Abram wrote in his 1996 book ‘The Spell of the Sensuous’ : “[…] the boundaries of a living body are open and indeterminate: more like membranes than barriers … so that it is very difficult to discern, at any moment, precisely where this living body begins and where it ends.” Such indeterminacies […]

1:19 PM | The Marshmallow, in herpetology and medicine
The 390 species of Anolis-lizards are generally considered insectivorous. Some also eat fruit and nectar. Recently, a new source of food for these New World reptiles was discovered: On the Consumption of Marshmallow Residues, an Atypical Food Item, by Anolis cristatellus Duméril and Bibron, 1837 in Puerto Rico [LEB (Life: The Excitement of Biology) 2: […]

6:00 AM | A note on ADMM-GAMP
As we all know AMP solvers are a big deal because very few iterations are needed and because every iteration involve low complexity matrix-vecotr multiplies. So yesterday, after I featured Inference for Generalized Linear Models via Alternating Directions and Bethe Free Energy Minimization one of the authors, Phil Schniter, followed through with: Hi Igor,Thanks for helping to publicize our work on ADMM-GAMP.  I wanted to clarify something, though.  Rather than being merely an […]

3:54 PM | Holistic random encoding for imaging through multimode fibers
Sylvain just pointed out to me the following preprint on compressive imaging. I love the following excerpt:Thus, random scrambling gives an impression that it is only a hindrance; on the contrary, this traditional perspective can be challenged and improved. Holistic random encoding for imaging through multimode fibers by Hwanchol Jang, Changhyeong Yoon, Euiheon Chung, Wonshik Choi, Heung-No LeeThe input numerical aperture (NA) of multimode fiber (MMF) can be effectively increased by placing […]
