He literally came out for the team last year after never wrestling before. Iban Contreras (41-11), sixth, 285: “Iban is an incredible story. It was straight effort and desire personified.” He had a huge match in the blood round to beat a kid he lost to twice earlier. That says a lot because he is a first-time qualifier and wrestling the toughest competition. Tyler Pressel (39-19), seventh, 165: “Tyler wrestled probably the best tournament of the season at Ford Field. It just shows the heart and courage Josh has.” The first time being entered in district and he ends up placing in the state. Joshua McMillan (30-10), eighth, 150: “Josh had a tough draw right off the bat, but he battled back with a couple tough matches before his knee couldn’t take it anymore. Mirjavadi was one of six all-state Bulldogs. “Brayden was one of our captains and did a great job of leading this team,” Cali said. That gave him a 52-4 record for the season. Mirjavadi defeated Rockford’s Ryan Ahern 3-2 in the championship bout at Ford Field on March 4. In the final match of the opening day, he pinned Belleville’s Demond Harrison in 3:32. In his second match, he posted another first-period pin when he defeated Lake Orion’s Micah Wellbaum in 1:13. Mirjavadi, who helped Romeo reach the state semifinals in the team tournament, started the individual finals with a pin in 1:19 against Temperance Bedford’s Robbie Gossard. ROUNDUP: Verhaeghe sparks L’Anse Creuse to soccer victory over Fraser I could tell at our camp in the summer that he was really trying to be a student of the sport.” He kind of let down his guard for a second, and that was it. “After his loss in the state finals as a junior, Brayden put it in his mind that he wanted to get back to the finals and have another crack at the title,” Cali said. Mirjavadi’s drive to the title could be traced to when he lost a 3-1 decision to Temperance Bedford’s Rollie Denker in the 160 championship bout in 2022, Cali said. “What really stands out,” coach Jim Cali said, “is how he dominated on his way to the finals and avenging a loss in the finals where he wasn’t ever in trouble.” Brayden Mirjavadi, right, of Romeo wrestles Rockford’s Ryan Ahern in the 190-pound championship match at the Division 1 finals at Ford Field on March 4. Or sasers might be used for medical imaging and security screening in novel ways.The Romeo senior pinned three opponents before scoring a decision in the finals on the way to winning the state Division 1 wrestling championship at 190 pounds. In the future, a saser might spot defects in nanometer-scale objects like micro-electric circuits. Terahertz radiation is also used to reveal what's under your clothes in airport scans. The beam of coherent acoustic waves it produces has nanometer wavelengths (billionths of a meter). When stimulated by a power source (a light beam), the phonons multiply, bouncing back and forth between the layers of the lattice, until they escape out of the structure in the form of an ultra-high frequency phonon beam.Ī key factor in this new science is that the saser is the first device to emit sound waves in the terahertz frequency range, the researchers said. This is made out of around 50 super-thin sheets of two alternating semiconductor materials, gallium arsenide and aluminium arsenide, with each layer just a few atoms thick. The beam travels, not through an optical cavity like a laser, but through a tiny man-made structure called a superlattice. The saser mimics this technology, but using sound, to produce a sonic beam of phonons. This produces a coherent and controllable shining beam of laser light in which all the photons have the same frequency and rate of oscillation. In a laser, the photon beam is produced by stimulating electrons with an external power source so they release energy when they collide with other photons in a highly reflective optical cavity, the researchers explain. Albert Einstein laid the theoretical groundwork in 1917 for the invention of lasers, but the first working laser device wasn't created until 1960.Ī laser uses packets of electromagnetic vibrations called photons, the units of all light in the electromagnetic spectrum, including visible, infrared and X-rays.Ī saser uses sound waves composed of sonic vibrations called phonons. "Laser" stands for Light Amplification by the Stimulated Emission of Radiation.
