Ghita releases video for On My Mind

first_imgGhita has released the self-directed music video for her track On My Mind.She filmed the video in her homeland of Morocco. In the video Ghita and her friends move from urban locations to the country’s beautifully desolate wilderness. Watch the video below:Ghita commented, “On My Mind is about the deeply personal nature of each individual’s journey through life. I believe in my dreams and my ambitions, and I want to inspire people to do the same. I also wanted to address female empowerment. In Morocco, more and more women are fighting for their right to be heard. They’re standing up for emancipation, for equality between genres, and to bring down this patriarchal society.We had a lot of fun making the video. I got to meet an amazing group of women and it was hilarious from start-to-finish, as if we’d known each other forever. I hope we can be reunited soon.”Ghita is inspired by North African rhythms and the vibrant world of Afrobeats as well as elements of R&B, rap and hip-hop. She sings in English, French (her mother tongue) and Arabic.For her tracks so far, Ghita has already hit 5 million streams, with fan favourite HateULoveU hitting Spotify’s Global Viral Top 50.last_img read more

6G to Use Ultra-Rapid Electro-Optical Modulators to Convert Terahertz into Optical Signals

first_imgWhile the world eagerly waits to use the full potential of 5G cellular technology, researchers are now already working on technologies for the next generation of wireless data transmission – “6G”. The sixth generation update is expected to have far higher transmission rates and shorter delays than 5G, and also an increased device density, with artificial intelligence (AI) playing an important role. But on the way towards the sixth generation cellular network, many challenges have to be mastered regarding both individual components and their interaction.Future wireless data networks will have to reach higher transmission rates and shorter delays, while supplying an increasing number of end devices. For this purpose, network structures consisting of many small radio cells will be required. To connect these cells, high-performance transmission lines at high frequencies up to the terahertz range will be needed. Moreover, seamless connection to glass fiber networks must be ensured, if possible. Addressing the challenge, researchers at the Karlsruhe Institute of Technology (KIT), as published in the journal Nature Photonics, have used ultra-rapid electro-optical modulators to convert terahertz data signals into optical signals.The next generation of wireless networks will consist of a number of small radio cells to quickly and efficiently transmit large data volumes. These cells will be connected by transmission lines, which can handle tens or even hundreds of gigabits per second per link. The necessary frequencies are in the terahertz range, i.e. between microwaves and infrared radiation in the electromagnetic spectrum. In addition, wireless transmission paths have to be seamlessly connected to glass fiber networks. In this way, the advantages of both technologies, i.e. high capacity and reliability as well as mobility and flexibility, will be combined.Scientists of the KIT Institutes of Photonics and Quantum Electronics (IPQ), Microstructure Technology (IMT), and Radio Frequency Engineering and Electronics (IHE) and the Fraunhofer Institute for Applied Solid State Physics IAF, Freiburg, have now developed a promising approach to converting data streams between the terahertz and optical domains. As reported in Nature Photonics, they use ultra-rapid electro-optical modulators to directly convert a terahertz data signal into an optical signal and to directly couple the receiver antenna to a glass fiber.In their experiment, the scientists selected a carrier frequency of about 0.29 THz and reached a transmission rate of 50 Gbit/s. According to Professor Christian Koos, Head of IPQ and Member of the Board of Directors of IMT, the modulator is based on a plasmonic nanostructure and has a bandwidth of more than 0.36 THz. The results reveal the great potential of nano-photonic components for ultra-rapid signal processing. The concept demonstrated by the researchers will considerably reduce the technical complexity of future radio base stations and enable terahertz connections with very high data rates – several hundred gigabits per second are feasible.Click here to read the published paper.last_img read more

No plans to abort tournaments, announce winners

first_imgChairman of the Georgetown Cricket Association (GCA) Competition’s Committee Shaun Massiah says they do not intend to prematurely cancel and announce winners of a number of tournaments which have been stalled due to the ongoing COVID-19 pandemic. If a decision is made to cancel the tournaments, then the winners would be announced based on point standings, similar to what Cricket West Indies (CWI) did earlier this year to end the regional four-day tournament with two rounds to go.  “Even at our last Zoom meeting, we didn’t discuss aborting any of the tournaments,” Massiah affirmed. He noted that all tournaments will resume as per normal once the COVID-19 pandemic is under control to give sponsors their due mileage. “We struggle to get sponsorship so if we abort those tournaments and announce winners, it might be difficult to get new sponsorship after this COVID – 19 to get cricket playing… so we are going to run with those tournaments until they are completed,” the committee head noted.  Cricket in the Capital City, like many other parts of Guyana, continues to be a backyard past time since the outbreak of the new Coronavirus. There has been a prolonged absence of the sport in 2020 due to several factors starting with Guyana’s Mashramani celebrations along with the holding of General and Regional Elections. The outbreak of the new Coronavirus has since contributed to the hiatus, as the Georgetown Cricket Association (GAC) recently announced that it will be following the Ministry of Public Health’s recommendation to promote social distancing as a means to halt the spread of the virus.  The move has stalled cricket action in the New Building Society (NBS) 40 overs, second-division tournament, the Noble House Seafoods, second-division, two-day tournament and GISE, Star Party Rental and Trophy Stall first-division.last_img read more
