The bright spheres symbolize bound charge carriers (negative and positive) in the material. The light beam separates these charges, which are then deflected in different ways in the applied magnetic field. With the CLIMAT method, around 14 different parameters of the transport properties in semiconductors can be measured with a single measurement, for example, density, lifetime, diffusion lengths, and mobility.

Google launched a new measurement tool for advertisers in anticipation of its plan to phase out third-party cookies later this year. Meridian, an open-source Marketing Mix Model (MMM), has been introduced to help advertisers analyze campaign performance while prioritizing user privacy. Accessibility. Meridian is currently available to select users. However, Google plans to make it accessible to all marketers and data scientists in the near future. What are MMMs? Marketing Mix Models are statistical analysis…

LIGO has confirmed 90 gravitational wave detections so far, but physicists want to detect more, which will require making the experiment even more sensitive. And that is a challenge.  “The struggle of these detectors is that every time you try to improve them, you actually can make things worse, because they are so sensitive,” says Lisa Barsotti, a physicist at the Massachusetts Institute of Technology. Nevertheless, Barsotti and her colleagues recently pushed past this challenge, creating a device that will allow…

This Hubble Space Telescope image shows the powerful gravity of a galaxy embedded in a massive cluster of galaxies producing multiple images of a single distant supernova far behind it. The image shows the galaxy’s location within a large cluster of galaxies called MACS J1149.6+2223, located more than 5 billion light-years away. In the enlarged inset view of the galaxy, the arrows point to the multiple images of the exploding star, named Supernova Refsdal, located 9.3 billion light-years from Earth.Credit: NASA, ESA,…

Based on household surveys in sub-Saharan Africa, the first-of-its-kind analysis, published in Proceedings of the National Academy of Sciences, underscores the importance of accurately defining and measuring poverty.…

Homegrown short video and social media platforms Moj and ShareChat on Wednesday said they have partnered with the global media measurement platform Integral Ad Science (IAS) to deploy media quality measurement for the advertisers on its platforms."This is our very long term agenda of trying to tell the marketers in India, that when consumers have moved to short form video, it is high time that they utilize these platforms to do their storytelling," Gaurav Jain, chief business officer of Moj and ShareChat told ET.Elevate…

Several innovations in the new sample rod including the sample holder enable temperature measurements with the highest precision. Credit: D. Kojda/HZBResearchers at HZB have created an innovative technique to precisely measure minuscule temperature variations as small as 100 microkelvin in the thermal Hall effect, overcoming previous limitations caused by thermal noise. By applying this technique to terbium titanate, the team showcased its effectiveness in producing consistent and dependable outcomes. This advancement in…

When streams of ultra-fast protons collide, a Higgs boson might pop into existence for the briefest instant before decaying into lighter particles.In that moment, physicists can work backwards to estimate the mass of what could be the most important and yet most elusive particle in the Standard Model.Having crunched the numbers on a mind-boggling number of proton collisions using the Large Hadron Collider (LHC), physicists now have the most precise figure yet for this all-important property.First reported in July, the…
