Four figures in the Book of Revelation who symbolize the evils to come at the end of the world. The figure representing conquest rides a white horse I just noticed it in this video too. :

The University of Tennessee state college system announced this fall it will try to limit on campus population with as much computer courses as possible.
If I was going to college today, I do not know if I could do this or pay lots of money to go to school at home.
I really wonder how my grandkids will go back to their local schools this fall?
I have them in kindergarten on up.
Such weird times!

Tightening up facial biometrics
by David Bradley 27 May 2020
Facial biometrics for security applications is an important modern technology. Unfortunately, there is the possibility of "spoofing" a person's face to the sensor or detection system through the use of a photograph or even video presented to the security system. A team from China has now developed a counter-measure that could preclude face spoofing and make such biometric security systems far less prone to abuse. The team reports details in the International Journal of Computational Science and Engineering.
Fei Gu, Zhihua Xia, Jianwei Fei, Chengsheng Yuan, and Qiang Zhang of Nanjing University of Information Science and Technology, explain how anti-spoofing technology usually looks to illumination differences, colour differences, or textures differences to spot issues with the presented face to determine whether or not the face is a photo or video rather than a live human in front of the security camera. However, even these approaches are vulnerable.
In order to make a stronger anti-spoofing system, the team has proposed a method based on various feature maps and convolution neural networks for photo and video replay attacks. They explain that facial contour and specularly reflected features are taken into account when verifying a face so that depth and width can be determined, aspects of a living face that are not present in a photograph. Their proof of principle shows remarkable performance against multiple datasets and shows that the method can defend not only photo attack, but also video replay attack with a very low error rate.

Bricks made from plastic, organic waste New binding solution targets construction uses
Date: May 26, 2020
Source: Flinders University
Summary:
Revolutionary 'green' types of bricks and construction materials could be made from recycled PVC, waste plant fibers or sand with the help of a remarkable new kind of recently discovered rubber polymer. The rubber polymer, itself made from sulfur and canola oil, can be compressed and heated with fillers to create construction materials of the future.
The rubber polymer, itself made from sulfur and canola oil, can be compressed and heated with fillers to create construction materials of the future, say researchers in the Young Chemist issue of Chemistry -- A European Journal.
"This method could produce materials that may one day replace non-recyclable construction materials, bricks and even concrete replacement," says Flinders University organic chemist Associate Professor Justin Chalker.
The powdered rubber can potentially be used as tubing, rubber coatings or bumpers, or compressed, heated then mixed with other fillers to form entirely new composites, including more sustainable building blocks, concrete replacement or insulation.
Cement is a finite resource and heavily polluting in its production, with concrete production estimated to contribute more than 8% of global greenhouse gases emissions, and the construction industry worldwide accounting for about 18%.
"This is also important because there are currently few methods to recycle PVC or carbon fibre," says Associate Professor Chalker and collaborator Dr Louisa Esdaile, with support from other Flinders, Deakin University and University of Western Australia researchers.
"This new recycling method and new composites are an important step forward in making sustainable construction materials, and the rubber material can be repeatedly ground up and recycled," says lead author Flinders PhD Nic Lundquist. "The rubber particles also can be first used to purify water and then repurposed into a rubber mat or tubing."
Co-author and research collaborator Dr Louisa Esdaile says the important research looks at ways to repurpose and recycle materials, so that these materials are multi-use by design.
"Such technology is important in a circular economy," says Dr Esdaile, a special contributor to this month's Young Chemist issue of Chemistry -- A European Journal (ChemEurJ).
The new manufacturing and recycling technique, labelled 'reactive compression molding,' applies to rubber material that can be compressed and stretched, but one that doesn't melt. The unique chemical structure of the sulfur backbone in the novel rubber allows for multiple pieces of the rubber to bond together.
The project started two years ago in the Flinders University Chalker Laboratory as a third-year project by Ryan Shapter, with Flinders University PhD candidates Nicholas Lundquist and Alfrets Tikoalu and others contributing to the paper in this month's special Young Chemist issue of ChemEurJ.

Extremely intense radio burst detected from magnetar SGR 1935+2154
by Tomasz Nowakowski 28 May 2020

Using the Canadian Hydrogen Intensity Mapping Experiment (CHIME) radio telescope, astronomers have detected a bright, millisecond-duration radio burst from a galactic magnetar known as SGR 1935+2154. The discovery of such an extremely intense event, reported in a paper published May 20, could be important for improving the understanding of the origin of fast radio bursts (FRBs).
Magnetars are neutron stars with extremely strong magnetic fields, more than a quadrillion times stronger than the magnetic field of Earth. Decay of magnetic fields in magnetars powers the emission of high-energy electromagnetic radiation, for instance, in the form of X-rays or radio waves.
FRBs are intense bursts of radio emission lasting milliseconds and showcasing the characteristic dispersion sweep of radio pulsars. The physical nature of these bursts is unknown, and astronomers have considered a variety of explanations, including synchrotron maser emission from young magnetars in supernova remnants, and cosmic string cusps.
Located some 30,000 light years away in the Vulpecula constellation, SGR 1935+2154 is a galactic magnetar known to exhibit transient radio pulsations. Recently, it entered a period of unusually intense X-ray burst activity, and almost immediately, a team of astronomers led by Paul Scholz of the University of Toronto, Canada, started to observe this pulsar with CHIME. This resulted in the detection of a two-component bright millisecond radio burst from SGR 1935+2154 on April 28, 2020, similar to FRBs observed at extragalactic distances.
"The burst was detected simultaneously in 93 of the 1,024 CHIME/FRB formed beams, indicating an extremely bright event," the astronomers wrote in the paper.
The detected event consisted of two sub-bursts lasting 0.585 and 0.355 milliseconds, with the second occurring approximately 0.03 seconds after the first one. The dispersion measure of two burst components was found to be about 332.72 pc/cm3.
The fluence of the two sub-bursts was measured to be 480 and 220 kJy ms. The researchers noted that such values, together with the estimated distance to SGR 1935+2154, indicate a 400–800 MHz burst energy at a level of 30 decillion ergs, which is brighter than those of any radio-emitting magnetar known to date.
According to the paper, the new radio burst was identified when SGR 1935+2154 was in an extended active phase in which hundreds of high-energy bursts were reported. The researchers noted that the burst described in the study is by far the most radio-luminous such event detected from any magnetar in the Milky Way galaxy.
The astronomers ponder the possibility that the newly detected burst could be an FRB. First of all, the morphology of the radio burst resembles that of FRBs, in particular, the durations of its subcomponents are typical of the widths of bursts from 18 repeating FRB sources discovered by CHIME. Moreover, this burst was found to be only one to two orders of magnitude below the observed burst energies for typical FRBs, but it could have similar energies to some identified FRBs if they were at their nearest possible distance.
Whether the newfound radio burst from SGR 1935+2154 is an FRB remains an open question, but the researchers say that their detection may be helpful in filling the energy gap between the most luminous galactic sources and extragalactic FRBs.
"This event thus bridges a large fraction of the radio energy gap between the population of galactic magnetars and FRBs, strongly supporting the notion that magnetars are the origin of at least some FRBs," the authors of the paper concluded.
