Ethernet Controlled Noise Generators from 10 Hz to 18 GHz

first_imgAtlanTecRF launched their new RNG range of Broadband Noise Generators featuring Ethernet Control. Designed to form a built-in test facility in permanent installations of communications equipment or production test set-ups, these high output instruments operate at a frequency range from 10 Hz to 18 GHz in standard configurations with a capability to go beyond 40 GHz for custom applications.The nineteen standard models have total noise output power in the range -20 dBm to +30 dBm with noise densities from -122 dBc/Hz through to -13 dBc/Hz. Output level can be controlled either locally with convenient and easy to interpret increase/decrease front panel buttons and LCD readout or via ethernet with remote GUI derived from an mBed within the instrument.As an example, model RNG-1613 provides +10 dBm total noise power over a frequency band of 10 MHz to 2500 MHz and has the option of a 30 dB or 60 dB attenuation range with a highest level noise density of -84 dBc/Hz. This particular unit is therefore suitable for signal/noise measurements in most cellular bands as well as satellite communications L-band and also baseband frequencies for many radar and countermeasures applications.Among the many standard options is the facility for passing the signal under test through the instrument where it is combined with the white gaussian noise which can then be adjusted in amplitude. Another important option is the output mute which, operated remotely, allows the instrument to be on standby for short term tests as needed.The RNG series are all designed for 19” rack mount installation with 80-240 V, 50/60 Hz input, although portable and battery powered versions can also be supplied.last_img read more

Researches Discover THz Radiation Can Alter Proteins in Living Cells

first_imgResearchers from the RIKEN Center for Advanced Photonics, Tohoku University, National Institutes for Quantum and Radiological Science and Technology, Kyoto University, and Osaka University have discovered that terahertz radiation, contradicting conventional belief, can disrupt proteins in living cells without killing the cells. This finding implies that terahertz radiation, which was long considered impractical to use, may have applications in manipulating cell functions for the treatment of cancer, for example, but also that there may be safety issues to consider.Terahertz radiation is a portion of the electromagnetic spectrum between microwaves and infrared light, which is often known as the terahertz gap because of the lack so far of technology to manipulate it efficiently. Because terahertz radiation is stopped by liquids and is non-ionizing—meaning that it does not damage DNA in the way that x-rays do work is ongoing to put it to use in areas such as airport baggage inspections. It has generally been considered to be safe for use in tissues, though some recent studies have found that it may have some direct effect on DNA, though it has little ability to actually penetrate into tissues, meaning that this effect would only be on surface skin cells.One issue that has remained unexplored, however, is whether terahertz radiation can affect biological tissues even after it has been stopped, through the propagation of energy waves into the tissue. The research group from RAP and the National Institutes for Quantum and Radiological Science and Technology recently discovered that the energy from the light cold enter into water as a shockwave. Considering this, the group decided to investigate whether terahertz light could also have an effect like this on tissue.They chose to investigate using a protein called actin, which is a key element that provides structure to living cells. It can exist in two conformations, known as (G)-actin and (F)-actin, which have different structures and functions, as the (F)-actin is a long filament made up of polymer chains of proteins. Using fluorescence microscopy, they looked at the effect of terahertz radiation on the growth of chains in an aqueous solution of actin, and found that it led to a decrease in filaments.In other words, the terahertz light was somehow preventing the (G)-actin from forming chains and becoming (F)-actin. They considered the possibility that it was caused by a rise in temperature, but found that the small rise, of around 1.4 degrees Celsius, was not sufficient to explain the change, and concluded that it was most likely caused by a shockwave. To further test the hypothesis, they performed experiments in living cells, and found that in the cells as in the solution, the formation of actin filaments was disrupted. However, there was no sign that the radiation caused cells to die.It was quite interesting to see that terahertz radiation can have an effect on proteins inside cells without killing these cells themselves. It has also lead to an interest in looking for potential applications in cancer and other diseases.Terahertz radiation is coming into a variety of applications today, and it is important to come to a full understanding of its effect on biological tissues, both to gauge any risks and to look for potential applications.Click here to read the published paper.last_img read more

A few years ago, sakanila ‘yung No. 2 pick nakuha nila malakas na player tapos kinabukasan, pagkatapos ng draft, ipinamigay nila agad sa ibang team.”“Yun nakuha naman nila dun sa team na ‘yun, in fairness, malalakas din at nadala pa nga sila sa playoffs kamakailan lang.

Ancajas outboxes Sultan, retains IBF world title

first_imgSultan became the aggressor in the seventh to the ninth rounds as he unloaded numerous left and right combinations on Ancajas. Both had accidental head-butts in the ninth but not much damage was made.Ancajas regained his form in the 10th as he punished Sultan with attacks to the body and head. Sultan had his last push in the 12th but his wayward hits failed to hurt Ancajas.In the undercard, John Vincent Moralde of the Philippines scored two knockdowns on Ismail Muwendo as he surged to a unanimous-decision victory.“As expected, Jonas was a tough boxer to beat,” Ancajas said. “He had been hanging around the entire fight. I am just thankful to be part of history and that we both ended up without a serious gash.”This victory allowed the 29-year-old Ancajas to improve to a 30-1-1 win-loss-draw record including 20 knockout wins while the slate of Sultan, 26, dropped to 14-4-0 with nine wins via stoppage.The Ancajas-Sultan encounter was the first all-Filipino world title clash since Pancho Villa defeated compatriot Clever Sencio via unanimous decision to retain his world flyweight title in 1925./PN Jerwin Ancajas (left) tags Jonas Sultan with a right hook during their historic all-Filipino world title clash for the IBF super flyweight belt Sunday, May 27 at the Save Mart Center in Fresno, California. TOP RANK MANILA – Jerwin Ancajas retained his International Boxing Federation (IBF) super flyweight title with a unanimous-decision win over Jonas Sultan on Sunday at the Save Mart Center in Fresno, California.Raking in 119-109, 119-109, 117-111 from the judges, Ancajas successfully defended in clinical fashion for the fourth time the belt he won against the Puerto Rican veteran McJoe Arroyo in September 2016.Ancajas was aggressive in the first two rounds, with his fine jabs and 1-2 combinations against Sultan. The latter had his best round in the third when he rocked Ancajas with a loaded right to the face.Ancajas regained his footing in the next round onward as he unloaded calculated punches on Sultan.

Could Joe Johnson be Cavs’ Next Target?

first_imgThe NBA trade deadline passed Thursday at 3 PM, but the rumors of new acquisitions are far from over for the Cavaliers.A new report from Northeast Ohio Media Group’s Chris Haynes, claims that Joe Johnson of the Brooklyn Nets is a potential target for the Cavaliers. This isn’t the first time it’s been brought up, but Haynes’ report mentions “sources with knowledge of the dialogue.”Here’s a quote from Haynes’ report: “Should Johnson, 34, obtain a buyout of his $25 million salary for the season, Cleveland would be his next destination, sources with knowledge of the dialogue insist to cleveland.com.”This comes just two days after ESPN’s Dave McMenamin reported that the Cavs believed Johnson was not seeking a buyout and wanted to sign a multi-year deal with the rebuilding Nets.So whether something changed in two days, the two beat reporters have two different sources, or one of the two reports is inaccurate, Johnson’s future in Brooklyn and possibly Cleveland is up in the air.Johnson could provide scoring off the bench or possibly start at shooting guard, which would relegate J.R. Smith to a sixth-man role. It was evident for the past two weeks that Cavs’ General Manager David Griffin was looking to add depth at the wing positions and adding Channing Frye may have been enough, but it would not be a surprise at all if the Cavs were not finished there.Griffin has a relationship with Johnson from their time together in Phoenix and his relationship with Frye played a big role in wanting to bring the stretch-four to Cleveland. Johnson could possibly provide some minutes for LeBron James. It’s no secret the Golden State Warriors are the team to beat in the NBA and the small lineup the Warriors use could be something the Cavs look to matchup with. The addition of Johnson could give the Cavs one more piece to match up with the likes of Harrison Barnes, Klay Thompson, Andre Iguodala, Leandro Barbosa, Brandon Rush, Ian Clark or Shaun Livingston. Right now the Cavs most dependable wing players are Iman Shumpert, Smith, LeBron, and Richard Jefferson. Cleveland has two open roster spots at the moment, so aside from the financial cost, which would likely be the veterans’ minimum, it wouldn’t create much of a burden on the Cavs. Unless you are of the belief that Johnson would somehow mess with the team chemistry.For a three to four month rental, it makes sense to add some extra scoring to a second-unit that has not been as impactful as some hoped. The depth that we were raving about at the start of the season has diminished to an eight-man rotation for the most part. These rumors involving Johnson may play out over the course of weeks, but for the Nets and the Cavs, it would make the most sense for something to happen sooner rather than later.

UFC returning to Saitama on Sept. 20

first_img“This is actually a fight most fans have wanted for the last couple of years,” Nelson told The Japan Times Thursday afternoon. “I’d say probably the biggest heavyweight fight in UFC history, from just what fans actually want.”Hunt’s last fight was Dec. 7, when he fought to a draw against Antonio Silva in a bout that’s already gone down as the stuff of legend. “He put on the best heavyweight fight I have ever seen in any MMA organization ever when he fought down in Australia against ‘Bigfoot Silva’,” UFC president Dana White said. “One of the greatest fights I’ve ever seen in my life.”That fight was the main event of the card in Brisbane, Australia, and Hunt is happy to be the main attraction once again.“It’s actually a bit of an honor for me to be able to headline here in Japan,” Hunt said. “I thank UFC for giving me the top billing again. Privileged and honored to fight here in Japan. It’s like my second home.”Also scheduled to compete is Rin Nakai, a 27-year-old Japanese fighter who will be making her UFC debut while also participating in the first UFC fight in Asia to feature female athletes.“UFC is uncharted territory for me,” Nakai said. “So my feeling is that I’m a newcomer and I’d like to stick to the basics. I’d like to fight with that in mind.”Nakai is 16-0-1 as an MMA fighter, but is taking a step up to compete in UFC.“A lot of people have come from a lot of different shows around the world,” White said. “You’re first fight in UFC is always … people get very nervous, no matter how big the event they’ve been in before that, and she’s coming into a big fight with a tough well-rounded veteran in Miesha Tate.”Tate is a former Strikeforce Women’s Bantamweight champion and 2008 FILA Grappling World championships silver medalist. She’s 14-5 in her MMA career and the first woman to win two UFC “Fight of the Night” awards.Tate is a formidable opponent, but there’s no understating the opportunity that lies in front of Nakai. It’s a chance so great White agreed when someone asked if Nakai might be one of the most important Japanese fighters in the world right now.“I didn’t really think about that way until you said it, but it’s true,” he said. “Because if she wins this fight, she’s in line for a fight with Ronda Rousey (the current UFC Women’s Bantamweight champion), which is huge. Massive.”Hunt is no stranger to Japan. The New Zealander, known as the “Super Samoan,” is formerly of Japan-based MMA circuit PRIDE and has also fought K-1 matches in Japan.He expects the bout against the 182-cm, 118-kg Nelson in September to live up to expectations MMA fans have when two heavyweight clash.“I think the aspect of the smaller guys is they’re more technical and you see a lot technique-wise, ground and standing,” the 178-cm, 119-kg Hunt said. “With the heavy guys, there’s not much technique. The fight could end anytime with a knockout. People like to see people get knocked out. This is the whole business, and that’s why the heavyweights get the top billing, because people want to see people fly out the ring, or the octagon.”A number of Japanese fighters, including Takanori Gomi, Norifumi “Kid” Yamamoto, and Yoshihiro “Sexyama” Akiyama are expected to take part. White would also like to have a number of fighters come over from the U.S. to compete.As of right now, the actual card, including matchups, is still undecided.“I would like to be in title fights in the future, so I want to face a quality opponent,” Gomi said. “I’d like to fight against a quality opponent and I’d like put on an exciting fight for Japanese fans.”Nelson thinks Japanese fighters put on a good show for their fans, and says he and Hunt have that same fire.“What I’ve seen is that most Japanese fighters have more of that warrior spirit versus just being an athlete,” Nelson said. “An athlete is just trying to go and win for 15 minutes or 25 minutes, whatever. While a warrior is like, ‘If there was no cage, if there was no ring if there was no anything, I’m going to win this fight. My life depends on it.’“That’s why I respect Mark, because Mark is that type of fighter. I’m that type of fighter. That’s what makes exciting fights. Fighters that fight.” GET THE BEST OF THE JAPAN TIMES KEYWORDS RELATED PHOTOS The Ultimate Fighting Championship is bringing its brand of mixed-martial arts back to Japan with not only one of the most highly anticipated heavyweight bouts in recent memory, but also what may be among the most important UFC debuts by a Japanese fighter in some time.UFC Fight Night Japan 2014 is scheduled for Sept. 20 at Saitama Super Arena.
