WASHINGTON — The third satellite of the GPS 3 constellation arrived Feb. 5 at Cape Canaveral Space Force Station, Florida, where it will undergo final testing and checkout before its scheduled launch in April aboard a SpaceX Falcon 9 rocket.
The GPS 3 satellite was flown from Lockheed Martin’s assembly line in Colorado aboard a U.S. Air Force C-17 cargo aircraft.
In a news release on Friday, the U.S. Space Force Space and Missile Systems Center said the next steps are to prepare the GPS 3 SV-3 for propellant loading and fairing encapsulation before it’s horizontally integrated with a Falcon 9 launch vehicle.
TrackML was a Kaggle competition in 2018 with $25 000 in cash prizes where the challenge was to reconstruct particle tracks from 3D points left in silicon detectors. CERN (the European Organization for Nuclear Research) provided data over particles collision events. The rate at which they occur over there is in the neighborhood of hundreds of millions of collisions per second, or tens of petabytes per year. There is a clear need to be as efficient as possible when sifting through such an amount of data, and this is where machine learning methods may be of help.
Particles, in this case protons, are boosted to high energies inside the Large Hadron Collider (LHC) — each beam can reach 6.5 TeV giving a total of 13 TeV when colliding. Electromagnetic fields are used to accelerate the electrically charged protons in a 27 kilometers long loop. When the proton beams collide they produce a diverse set of subatomic byproducts which quickly decay, holding valuable information for some of the most fundamental questions in physics.
Detectors are made of layers upon layers of subdetectors, each designed to look for specific particles or properties. There are calorimeters that measure energy, particle-identification detectors to pin down what kind of particle it is and tracking devices to calculate the path of a particle. [1] We are of course interested in the tracking, tiny electrical signals are recorded as particles move through those types of detectors. What I will discuss is methods to reconstruct these recorded patterns of tracks, specifically algorithms involving machine learning.

South Korean TV broadcaster MBC recently aired a Korean language documentary that centers on a family’s loss of their young daughter, seven-year-old Nayeon. Using the power of photogrammetry, motion capture, and virtual reality, the team recreated Nayeon for one last goodbye with the family’s mother, Ji-sung.
Innovation comes from all ages, and this is further seen in the story of Xóchitl Guadalupe Cruz, an eight-year-old girl from Chiapas, Mexico who invented an entirely solar-powered device for heating water. The impact her invention could have on others around the world is immense, and this has inspired the UNAM’s (National Autonomous University of Mexico) Institute of Nuclear Sciences to award her.
To those in developed countries, her invention may not seem all that revolutionary as access to warm or hot water is commonplace, but for those in many other areas of the world, including her town in Mexico, this would be a luxury.
Cadillac is fully aware it needs to continue launching new vehicles that are not only relevant for the times but also offer something new. That something is — big surprise — electrification. At the moment, GM’s luxury brand does not sell an EV and its only hybrid model, the Cadillac CT6 Hybrid, is about to be discontinued. Eventually, the just-revealed 2021 Cadillac Escalade will likely offer a plug-in hybrid variant and, perhaps, an all-electric one as well. Thing is, Cadillac can’t wait that long for an Escalade EV, but it turns out an alternative is coming very soon.
GM President Mark Reuss announced last week at the automaker’s Capital Markets Day presentation the brand’s first-ever EV will debut this April. And yes, it will be a crossover, a fact that was announced a year ago at the Detroit Auto Show. Oddly, Cadillac did not preview this vehicle with a concept in the Motor City.
Scientists at Newcastle University, in the United Kingdom, have 3D printed the world’s first real human corneas. This is unbelievable news since today, there is a significant shortage of corneas available for transplant. In the future, this printing technique could be used to ensure an unlimited supply of corneas.
The cornea is the outermost layer of the human eye and it has an important role in focusing vision. Statistics show that there are currently 10 million people worldwide requiring surgery to prevent corneal blindness as a result of diseases such as trachoma, an infectious eye disorder. On top of that, there are an additional 5 million people who suffer total blindness due to corneal scarring caused by burns, lacerations, abrasion or disease.
For the first time, researchers from the Universities of Bonn and Strasbourg have simulated the formation of galaxies in a universe without dark matter. To replicate this process on the computer, they have instead modified Newton’s laws of gravity. The galaxies that were created in the computer calculations are similar to those we actually see today. According to the scientists, their assumptions could solve many mysteries of modern cosmology. The results are published in the Astrophysical Journal.
Cosmologists today assume that matter was not distributed entirely evenly after the Big Bang. The denser places attracted more matter from their surroundings due to their stronger gravitational forces. Over the course of several billion years, these accumulations of gas eventually formed the galaxies we see today.
An important ingredient of this theory is the so-called dark matter. On the one hand, it is said to be responsible for the initial uneven distribution that led to the agglomeration of the gas clouds. It also explains some puzzling observations. For instance, stars in rotating galaxies often move so fast that they should actually be ejected. It appears that there is an additional source of gravity in the galaxies that prevents this—a kind of “star putty” that cannot be seen with telescopes: dark matter.
Data can be stolen from an air gapped personal computer just by using variations in screen brightness. Researchers at Ben-Gurion University wrote a paper on it.
As the team defines them, “Air-gapped computers are systems that are kept isolated from the Internet since they store or process sensitive information.”
