GLENDALE Ariz — Full disclosure I missed the fi

first_imgGLENDALE, Ariz. — Full disclosure: I missed the first hour and a half of practice while helping out on Burns and Gambo, so there are probably things I missed. Hope you listened to the show and enjoyed it. On that note, here’s what I did get to see.Of Note– Kevin Minter, Jonathan Cooper and Max Starks were once again held out of practice. – Tyrann Mathieu and Alameda Ta’amu, who were both activated from the physically unable to perform list Tuesday, got some work with the scout team against the first-team offense Thursday. For Mathieu, it was his first chance to get in on some tackling. Comments   Share   “When you lose Karlos (Dansby) and obviously (Darnell) Dockett and Daryl (Washington), those are very difficult shoes to fill. You’re always looking to fill those shoes, but at the end of the day, I don’t know if you fill those shoes. There’s not a bunch of Darnell Docketts out there, there’s not a bunch of Karloses, there’s not a bunch of guys out there that are athletic freaks like Daryl was. But you make do. You find guys that can come in and play and bring different things to the defense, bring different qualities of leadership, playmaking abilities. Offensively, you look at it and we say we need to be kind of the backbone, we need to be counted on to win games at the end of the games. We’ve got to pick up and continue to improve week after week. Who knows how the season’s going to shake down, but we need to be ready offensively, to be ready to carry.” – QB Carson Palmer on the offense having to pick up the slack with all the missing pieces on defense“Everybody expects us to run for 200 yards a game in only a short amount of time in the preseason with the amount of touches we get. It doesn’t work like that, it’s not that easy. I know if they look around the league, not many guys are running the ball really well, and the guy who is is usually the guy at the end because he’s getting the most touches more than anything. So I think that everybody needs just to relax and just be excited for when the season gets here because we’ll be where we need to be.” – Running back Jonathan Dwyer on concerns over the running game due to a lack of preseason production – / 7 The 5: Takeaways from the Coyotes’ introduction of Alex Meruelo Derrick Hall satisfied with D-backs’ buying and sellingcenter_img Former Cardinals kicker Phil Dawson retires Top Stories Grace expects Greinke trade to have emotional impact – Tony Jefferson picked off a couple of passes, and Deone Bucannon also nabbed an interception. While you can’t learn a ton from practices, it appears both have made great progress in the coverage department.-Larry Fitzgerald caught a touchdown pass in what looked like the two-minute offense toward the end of practice.Stat of the DayIn a 2007 Arizona victory in Cincinnati, then-Cardinals cornerback Antrel Rolle intercepted then-Bengals quarterback Carson Palmer three times, returning two of them for touchdowns. He scored on the third interception, as well, but the touchdown was nullified when Antonio Smith was called for an unsportsmanlike conduct penalty on the return.Quotes of the Day“I knew he was tough as hell. We tried to knock him out; you could never knock him out. We know he had the freak injury in the playoff game. If he had not gotten hurt, I don’t know if we would have won the game. And he always had that tremendous deep ball. So yeah, I kind of didn’t know what kind of gym rat he was, but I knew he was tougher than hell and a really good thrower of the football. So now that we’ve got the gym rat, I really like it.” – Head coach Bruce Arians on if he knew what he needed to know about Carson Palmer before trading for himlast_img read more

Square Kilometer Array scales back ambitions for first phase

Required fields are indicated by an asterisk (*) A baseline design for SKA was drawn up during the planning stage, and teams in South Africa and Australia are in the process of building two prototype arrays to test some of the technology: the 36-dish Australian SKA Pathfinder (ASKAP) and the 64-dish MeerKAT array in South Africa.In July 2013, the SKA board set a cost cap for phase 1, also called SKA1, of €650 million. Since then there has been a worldwide effort by working groups and advisory boards to see what was possible within that budget. “We pulled it all together last October so that we could understand the costs to deliver the science goals,” Diamond says.The final plan for SKA1, announced today, has two components. The first is a midfrequency array with about 200 dish antennas in South Africa that will incorporate MeerKAT—down from roughly 250 in the original baseline plan. The second part is a low-frequency array in Australia that will be made up of about 130,000 so-called dipole antennas (similar to a rooftop TV aerial). The original plan called for 250,000 antennas.The original plan also included a third element, a specialized midfrequency survey telescope in Australia based around ASKAP but with 60 additional dishes. The dishes would be fitted with novel detectors called phased array feeds that can view a wide swath of the sky at once for rapid surveying. That will now have to wait for phase 2 of the project. Best, who served on a science advisory panel to SKA during the reconfiguring process, says that the midfrequency array in South Africa will still be able to do surveys of the radio sky, only more slowly because of its narrower field of view.Best says it was a “pretty unanimous decision” among the science advisers to follow this path. “Given the cost cap, it was more important to make two groundbreaking instruments,” he says. “It hasn’t lost any capabilities that the original baseline had,” he adds, but some goals may require more observing time and so “a little more give and take” may be required.SKA1 has two key science goals. The first is to detect the metronomic signals from many pulsars—rapidly spinning neutron stars that send out very regular radio pulses—so that tiny variations in the timing of their pulses can reveal the passage of gravitational waves. The second is to map out a very faint signal from neutral hydrogen gas through the history of the universe right back to the time when the first stars and galaxies were forming. “A massive range of other science is possible,” Diamond says.SKA is just starting to set the research goals for the second phase, Diamond says, and those will inform decisions about the size of the final instrument, which will likely have about 2000 dishes in Africa and up to a million dipoles in Australia. Most of the receiving hardware is, however, not a radical departure from what exists today. It is the data handling, computing, and software that remains unproven. “This is the biggest challenge we face,” Diamond says.Scaling back SKA1 is a bit of a disappointment, Best acknowledges. “But it doesn’t change things. The intention for the full SKA is the same, there is just less in the first phase,” he says.center_img Country * Afghanistan Aland Islands Albania Algeria Andorra Angola Anguilla Antarctica Antigua and Barbuda Argentina Armenia Aruba Australia Austria Azerbaijan Bahamas Bahrain Bangladesh Barbados Belarus Belgium Belize Benin Bermuda Bhutan Bolivia, Plurinational State of Bonaire, Sint Eustatius and Saba Bosnia and Herzegovina Botswana Bouvet Island Brazil British Indian Ocean Territory Brunei Darussalam Bulgaria Burkina Faso Burundi Cambodia Cameroon Canada Cape Verde Cayman Islands Central African Republic Chad Chile China Christmas Island Cocos (Keeling) Islands Colombia Comoros Congo Congo, the Democratic Republic of the Cook Islands Costa Rica Cote d’Ivoire Croatia Cuba Curaçao Cyprus Czech Republic Denmark Djibouti Dominica Dominican Republic Ecuador Egypt El Salvador Equatorial Guinea Eritrea Estonia Ethiopia Falkland Islands (Malvinas) Faroe Islands Fiji Finland France French Guiana French Polynesia French Southern Territories Gabon Gambia Georgia Germany Ghana Gibraltar Greece Greenland Grenada Guadeloupe Guatemala Guernsey Guinea Guinea-Bissau Guyana Haiti Heard Island and McDonald Islands Holy See (Vatican City State) Honduras Hungary Iceland India Indonesia Iran, Islamic Republic of Iraq Ireland Isle of Man Israel Italy Jamaica Japan Jersey Jordan Kazakhstan Kenya Kiribati Korea, Democratic People’s Republic of Korea, Republic of Kuwait Kyrgyzstan Lao People’s Democratic Republic Latvia Lebanon Lesotho Liberia Libyan Arab Jamahiriya Liechtenstein Lithuania Luxembourg Macao Macedonia, the former Yugoslav Republic of Madagascar Malawi Malaysia Maldives Mali Malta Martinique Mauritania Mauritius Mayotte Mexico Moldova, Republic of Monaco Mongolia Montenegro Montserrat Morocco Mozambique Myanmar Namibia Nauru Nepal Netherlands New Caledonia New Zealand Nicaragua Niger Nigeria Niue Norfolk Island Norway Oman Pakistan Palestine Panama Papua New Guinea Paraguay Peru Philippines Pitcairn Poland Portugal Qatar Reunion Romania Russian Federation Rwanda Saint Barthélemy Saint Helena, Ascension and Tristan da Cunha Saint Kitts and Nevis Saint Lucia Saint Martin (French part) Saint Pierre and Miquelon Saint Vincent and the Grenadines Samoa San Marino Sao Tome and Principe Saudi Arabia Senegal Serbia Seychelles Sierra Leone Singapore Sint Maarten (Dutch part) Slovakia Slovenia Solomon Islands Somalia South Africa South Georgia and the South Sandwich Islands South Sudan Spain Sri Lanka Sudan Suriname Svalbard and Jan Mayen Swaziland Sweden Switzerland Syrian Arab Republic Taiwan Tajikistan Tanzania, United Republic of Thailand Timor-Leste Togo Tokelau Tonga Trinidad and Tobago Tunisia Turkey Turkmenistan Turks and Caicos Islands Tuvalu Uganda Ukraine United Arab Emirates United Kingdom United States Uruguay Uzbekistan Vanuatu Venezuela, Bolivarian Republic of Vietnam Virgin Islands, British Wallis and Futuna Western Sahara Yemen Zambia Zimbabwe The consortium that will build the world’s biggest radio telescope, the Square Kilometer Array (SKA), today announced the final scope of the first phase of the project, which is due to begin construction in 2018 and be completed by 2023. Although it has had to be scaled back to stay within the available funding, the project will still be able to achieve all of its key scientific goals.“You have to make compromises when you are cutting your cloth to the funding you’ve got,” says SKA Director Philip Diamond. “There is a scaling down, but it is still a highly transformational instrument,” says astrophysicist Philip Best of the University of Edinburgh’s Institute for Astronomy in the United Kingdom.SKA, funded by 11 countries from around the globe, will be built partly in southern Africa and partly in Australia. The plan is to first build a pilot instrument, which, as well as advancing astronomy itself, will also prove that the principle behind the giant telescope actually works before the construction of phase 2 between 2023 and 2030. The final instrument will have dishes and antennas stretching across most of Africa as well as Australia and will have a total collecting area of a square kilometer.last_img read more
