ImageSnippets lets you create a responsive image gallery using ImageSnippets end point, username, property and object.
Major features in ImageSnippets allows you to:
Add/remove/edit multiple galleries.
Regenerate your gallery manually or schedule an automated task.
We are using REST API (https://www.setcronjob.com/) that will allow you to create a cron job service for regenerating your gallery. To do so, you have to create an account and generate API token.
This looks interesting and reminds me I want to take a closer look at some linked data technology.

Study in bacteria shows how regularly DNA changes and how few of those changes are deadly
This is a rather cool little experiment.

The ability to integrate information in the brain is considered to be an essential property for cognition and consciousness. Integrated Information Theory (IIT) hypothesizes that the amount of integrated information ( Φ ) in the brain is related to the level of consciousness. IIT proposes that, to quantify information integration in a system as a whole, integrated information should be measured across the partition of the system at which information loss caused by partitioning is minimized, called the Minimum Information Partition (MIP). The computational cost for exhaustively searching for the MIP grows exponentially with system size, making it difficult to apply IIT to real neural data. It has been previously shown that, if a measure of Φ satisfies a mathematical property, submodularity, the MIP can be found in a polynomial order by an optimization algorithm. However, although the first version of Φ is submodular, the later versions are not. In this study, we empirically explore to what extent the algorithm can be applied to the non-submodular measures of Φ by evaluating the accuracy of the algorithm in simulated data and real neural data. We find that the algorithm identifies the MIP in a nearly perfect manner even for the non-submodular measures. Our results show that the algorithm allows us to measure Φ in large systems within a practical amount of time.

QUANTUM gravitational effects are usually ignored in calculations of the formation and evolution of black holes. The justification for this is that the radius of curvature of space-time outside the event horizon is very large compared to the Planck length (Għ/c3)1/2 ≈ 10−33 cm, the length scale on which quantum fluctuations of the metric are expected to be of order unity. This means that the energy density of particles created by the gravitational field is small compared to the space-time curvature. Even though quantum effects may be small locally, they may still, however, add up to produce a significant effect over the lifetime of the Universe ≈ 1017 s which is very long compared to the Planck time ≈ 10−43 s. The purpose of this letter is to show that this indeed may be the case: it seems that any black hole will create and emit particles such as neutrinos or photons at just the rate that one would expect if the black hole was a body with a temperature of (κ/2π) (ħ/2k) ≈ 10−6 (M⊙/M)K where κ is the surface gravity of the black hole1. As a black hole emits this thermal radiation one would expect it to lose mass. This in turn would increase the surface gravity and so increase the rate of emission. The black hole would therefore have a finite life of the order of 1071 (M⊙/M)−3 s. For a black hole of solar mass this is much longer than the age of the Universe. There might, however, be much smaller black holes which were formed by fluctuations in the early Universe2. Any such black hole of mass less than 1015 g would have evaporated by now. Near the end of its life the rate of emission would be very high and about 1030 erg would be released in the last 0.1 s. This is a fairly small explosion by astronomical standards but it is equivalent to about 1 million 1 Mton hydrogen bombs.
In honor of pi day and the passing of Stephen Hawking, here’s one of his seminal papers published just before I was born.

Gary Posner, best known for pioneering research in organocopper chemistry, joined JHU faculty in 1969
I should know better about searching for obituaries. After hearing about Murray Sach’s passing I’ve just discovered that one of my organic chemistry professors has recently died as well.
I remember Dr. Posner well for his pointed use of the Socratic method, and in particular the day that my chemistry-related sir name caught his eye. I think he always expected that I would have been born a chemistry genius because of the name Aldrich. His expectations did make my orgo studies all the more fraught and worthwhile however.
I will point out in my day that the reaction that carried his name was ordered as the Corey-Posner-Whitesides-House reaction and not in the lesser order mentioned in the article.
Murray Sachs, of Arlington, MA, formerly of Baltimore, MD, on Saturday, March 3, 2018. Beloved husband of the late Merle (Diener) Sachs. Devoted father of Benjamin Sachs & his wife Lisa, and Jonathan Sachs & his wife Kate. Loving grandfather of Talia, Aviva, Zoe, Zander, Jonah, and Miriam. Loving uncle of Nancy Colier and Steven Shainberg.
Murray was a renowned scientist who received his undergraduate and graduate degrees in electrical engineering from MIT (B.S. ’62, M.S. ‘64, Ph.D. ‘66). He worked in the field of biomedical engineering, in particular using mathematics to model the way sound is received, transmitted, encoded, and comprehended between the ear and the brain, laying groundwork for advances such as the cochlear implant. He served as the Director of the Biomedical Engineering Department at Johns Hopkins University. Murray was elected a member of the Institute of Medicine of the National Academy of Sciences, and a member of the National Academy of Engineering for his scientific contributions and his leadership in biomedical engineering education. Murray is remembered as having a gentle soul, and as being a calm leader and generous mentor. He was a loving husband, beloved father, doting grandfather, and a deeply devoted colleague and friend. He will be profoundly missed.

In lieu of flowers, remembrances may be made to Michael J. Fox Foundation for Parkinson’s Research.
Saddened to hear about the passing of one of my college professors and a lion in the field of biomedical engineering. I’ve heard that there are forthcoming obituaries in the JHU Hub as well as the Baltimore Sun.
h/t to Guy Shechter for passing along the news

An interesting looking platform for podcasting. Looks like a paid service from the start though. Compare with Anchor.fm.
