An analytic formula describing the suppression of the equilibrium melting line by quenched point pinning disorder is compared to data from ac susceptibility and magnetization measurements in the mixed phase of the layered dichalcogenide low-T c superconductor 2H-NbSe 2. This material exhibits a sharp peak effect in the critical current j c close to the upper critical field H c2(T). Arguing that the disorder-suppressed melting line in this system is to be identified with the locus of peak positions of the critical current as magnetic field and temperature are varied, we demonstrate that this formula provides a remarkably accurate fit to the experimental data over three orders of magnitude in magnetic field. © 2012 American Physical Society.

Oak Hills Youth Athletics (OHYA) 6th Grade SILVER Oak Hills Youth Football Team capped off a 14-0 perfect season with a 2016 Battle in Rocky Top 11U National Championship in Knoxville, Tennessee. OHYA is a youth athletics organization sponsoring multiple sports programing for students in the Cincinnati Oak Hills Schools System. For the first time in the young history of OHYA, the organization has fielded an undefeated football team, Greater Miami Youth Football Conference (GMYFC) Super Bowl Champion, Southwestern Ohio Super Bowl Champion and now an Elite-All Star American Division National Champion at the Battle of Rocky Top. This is the first 6th Grade (11U) youth football team in Oak Hills Local Schools District history to achieve the coveted honor of National Champion. Oak Hills also becomes the first “school team” in the history of the Rocky Top National Championship Tournament to be slated in the American Division for Elite|Select |All-Star Teams and WIN the Division. School team is defined as a team, where all the players are students of only that single school district and typically a school team will play similar competition as in other school teams. Josh Jones, Battle in Rocky Top Tournament Director, stated that “…research depicted this Oak Hills (11U SILVER) Team as reportedly one of the best 11U teams ever to enter the tournament and for that reason they were posted into the nation’s most competitive 11U bracket versus select and all-star caliber teams.” According to the Oak Hills 6th Grade SILVER Head Coach Jim Bauer, “These young men established at the start of the season Four (4) Goals: 1. Win the competitive GMYFC League, 2. Win the GMYFC Super Bowl, 3. Win the Southwest Ohio Championship, and 4. Win the National Championship in Tennessee. They practiced and played as a unified TEAM the entire season and their accomplishments are validation. I can’t be prouder of these young men, their parents, our coaching staff. The entire Oak Hills community looks forward to their continued success in the coming years.” Oak Hills participated in the upper National Division of the Greater Miami Youth Football Conference (GMYFC), commonly known as the “Little GMYFC.” The team completed a 9-0 regular season with victories over Hamilton Blue Stars, Colerain Little Cardinals, Fairfield Indians Youth Football, Middletown Middies Youth Football, Princeton Vikings Youth Athletics, Mason Youth Football Comets and the Lakota East & West Tomahawks Football. Oak Hills also participated in cross-over league games with the Ohio Valley Youth Football League’s (OVYFL) Northwest Mighty Knights. All totaled in the regular season the Oak Hills 6th Grade SILVER Team scored 300 points and allowed only 12 points. GMYFC post season play included a 30-0 Oak Hills 6th Grade SILVER win over the Middletown Middies in the semi-finals. In the GMYFC Super Bowl, played at Princeton High School, the Oak Hills 6th Grade SILVER team delivered a 22-0 victory over the Lakota East Black Team 5 to secure Oak Hills’ first ever Super Bowl Championship. The two post season wins prompted the invitation to the first annual Southwest Ohio Super Bowl Championship to be played at the University of Miami’s Yager Stadium in Oxford, Ohio. Oak Hills, as the GMYFC Champions, would play host to the OVYFL League Champion the 6th Grade Edgewood Pee Wee Cougars. Oak Hills went on to win the inaugural championship, by a score of 22-0 and was crowned the 2016 Southwest Ohio Super Bowl Champions. On the weekend of November 18-20, 2016 Oak Hills Youth Football Team traveled to Knoxville, Tennessee to participate in the 2016 Battle in Rocky Top National Championship Tournament. This year 285 teams, representing 17 states, competed in the championships, across nine age brackets. The five 11U brackets contained 43 teams from 13 states including Missouri, Michigan, Minnesota, Tennessee, Illinois, Indiana, Ohio, Virginia, West Virginia, Kentucky, North Carolina, Georgia and Louisiana. In the American Division (aka: Elite-All Star Division) only six teams: including the Oak Hills 6th Grade SILVER, qualified. These six teams, Germantown Thoroughbreds, Beach Stampeders, EKAA Runners, East End Warriors, West Chester Outlawz and the Oak Hills Highlanders 6th Grade Silver had a combined three losses between them and represented the cream of the crop. Oak Hills first faced the East End Warriors out of Louisville, Kentucky. After giving up a 70 yard touchdown run on the opening drive, the Highlanders buckled down and denied the two-point conversion, and then scored 14 unanswered second half points to secure the victory. Championship Sunday in Knoxville meant meeting the winner of the other semi-final game the West Chester Outlaws from West Chester (Cincinnati), Ohio. This was a match-up that the Outlawz had been calling for all year. Both teams were familiar with each other having played in previous years, but this time it was for ALL THE MARBLES. The Outlawz took off to a 14-0 lead at half time dominating the clock in the first half. In the second half was a different story, the Highlander’s SILVER team took over and with less than a minute to play after blocking a punt, drove for a touchdown and then the game tying two-point conversion. As time elapsed in regulation, the outcome of the game turned to overtime (OT). Oak Hills received the ball to begin OT and on fourth down from the 14 yard line scored a touchdown and then connected on the two-point conversion to lead 22-14. The Outlawz on their OT possession drove the ball down to the one yard line and on fourth down were denied by the Oak Hills defense. This earned the Oak Hills Highlanders 6th Grade SILVER football TEAM the National Championship Title with a final score of 22-14 in overtime. Lee Hooks Head Coach of the select West Chester Outlaws shared “Congratulations on a great comeback victory! They (Oak Hills) could have easily folded, but they showed the heart of a true champion! ” Oak Hills Highlanders 6th Grade SILVER Defensive Coordinator Jason Schreiber called it “…an amazing game, an amazing season and a year that couldn’t have been scripted any better.” Oak Hills High School Head Football Coach Kyle Prosser stated “What this group of young gentlemen accomplished was amazing. Their unity and coach-ability gives our entire program something to look forward to. I'm very excited to have the entire 6th grade class playing together next year at the middle school. The future is extremely bright for this class and Oak Hills High School both academically and athletically!" For the season the Oak Hills Youth Athletics 6th Grade SILVER youth football team with their potent pass and run offense, their devastating defense and winning attitude accumulated 14 WINS, scored 410 points and allowed only 32 points against. As for the four goals set at the beginning of the year – WIN the league – CHECK, WIN the Super Bowl – CHECK, WIN the King Bowl – CHECK and WIN a National Championship – CHECK!!!!!! Congratulations to all the players and coaches of the 11U National Championship Oak Hills Youth Athletics 6th Grade SILVER youth football TEAM. Combined these students represent ALL three Oak Hills Middle Schools – Bridgetown Middle School, Rapid Run Middle School and Delhi Middle School – these schools are components of the Oak Hills Local School District and eventual feeders to the Oak Hills High School Football Program.

Stochastic fluxon dynamics and spatial ordering are studied in a superconducting Nb film patterned with a periodic (3×3 micron) square array of holes. First, imaging of the film is performed using Scanning Hall Probe Microscope following application of the random noise magnetic drive. We observe formation of the fluxon stripe patterns oriented preferentially along the principal axes of the array. Next, ac magnetic field is applied as superposition of harmonic and random noise components and the local magnetic response is probed with the micron-sized Hall sensor at a single array site. We find that hopping of the fluxons becomes synchronized with the harmonic driving at certain amplitude of the random noise; the latter is found to be dependent upon the harmonic drive frequency. We attribute our observations to the phenomenon of stochastic resonance that is ubiquitous in non-linear multi-level systems with dynamic threshold and discuss a possibility of flux manipulation using stochastically-resonant periodic driving. © Springer Science+Business Media New York (outside the USA) 2013.

In a superconducting film deposited on ferromagnetic substrate with perpendicular magnetic anisotropy, vortex matter is confined by the magnetic potential landscape. Using scanning Hall microscopy we visualize flux accumulation and removal in a superconductor-ferrimagnet (S/F) bilayer prepared by rf sputtering of thin niobium film on bismuth-doped rare-earth iron garnet. Penetration of the perpendicular magnetic field in the S/F bilayer follows magnetic domain boundaries and is laterally guided by the garnet magnetization component along the field direction. Upon field removal, localization of the remnant flux at the disclination points of the labyrinthine domain pattern is observed. Our experiments show evidence for strong vortex pinning due the special topology of the domain pattern. Ac magnetic imaging of the transport current distribution in the bilayer reveals complex flow paths commensurate with the magnetic domain boundaries. Topological magnetic pinning can be a useful tool for enhancement and control of critical current in thin film superconductors. © 2011 IOP Publishing Ltd.

The lamellar-forming 1-dimensional photonic films were prepared by three different molecular weight, but nearly symmetric poly(styrene-b-2-vinyl pyridine) (PS-b-P2VP) block copolymers. Propylene glycol monomethyl ether acetate (PGMEA) was used as solvent to spin-cast the films. The films were submerged into ethanol to swell P2VP block. As the molecular weight of the block copolymer increases, the film shows red-shifted color, because of longer periodic distance. In addition, the color of the films in ethanol was tuned by blending the PS-b-P2VP block copolymers. Copyright © 2016 American Scientific Publishers All rights reserved.

One dimensional structures often limit viewing angle as well as reflection color changes. We report a simple strategy to fabricate the ellipsoidal block copolymer nanoparticles, which have a wider viewing angle. The photonic crystals were made with the polystyrene-block-poly-2-vinyl pyridine(PS-b-P2VP) dispersed in chloroform. When the PS-b-P2VP was sonicated in polyvinyl alcohol(PVA), it became white emulsion. The photonic crystals were formed by self-assembly of block copolymers. We observed particle structure variations according to the difference in molecular weight, which were 52k-57k, 75k-66.5k, and 102k-97k. The swelling and nature of light scattering from structured particles changed by the addition of ethanol. The structure of the photonic crystals was investigated by the Transmission Electron Microscope and the color was measured by color-difference meter. The particles with low molecular weight showed the short wavelength reflection. © 2015 SPIE.
