Ganymede Age Threatened by Magnetism

first_imgThe biggest moon in the solar system is Ganymede, the third large moon out from Jupiter.  Larger than Mercury, Ganymede has a heterogeneous surface of dark and light areas (picture), grooved terrain, abrupt changes of landforms, and bright splashes where impacts have scarred its icy surface (gallery).  What goes on inside, though, is more surprising: it has an intrinsic magnetic field.  Researchers could only make it last for the assumed age of the solar system by appealing to “special conditions” that are not necessarily compatible with theories of its formation.    Bland, Showman and Tobie, writing in Icarus Dec 2008,1 realized that an intrinsic magnetic field requires a liquid core in which convection can occur to drive a dynamo.  A liquid core requires heat.  If they could find ways to stop runaway cooling inside the moon, maybe it would stay hot enough to maintain the magnetic field for 4.5 billion years.    They tried all kinds of things to keep the core hot.  They modeled Ganymede’s orbit passing through a resonance that would increase tidal pumping.  They varied the silicate rheology.  They altered Jupiter’s tidal dissipation factor.  They played with the size of the ice shell.  They imagined partial melting in the silicate mantle.  Nothing worked.  “We find that, contrary to expectations, there are no physically plausible scenarios in which tidal heating in the silicates is sufficient to cause the thermal runaway necessary to prevent core cooling.”    The only other possibility was if the amount of sulfur in the core was very low (less than 3%) or very high (greater than 21%).  Neither of those options was palatable, but they were stuck: “we must appeal to the special conditions described above to explain the presence of the field.”  At the end of the paper they tossed out one other possibility: late differentiation.  If the core didn’t form until 1 billion years ago (about 1/5 the assumed age of the moon), then convection might last for a billion years.  Either way requires invoking special conditions:We have shown that production of Ganymede’s magnetic field by secular cooling and chemical convection requires that a very specific set of conditions be met: the mass fraction of sulfur in the core must be low (or alternatively very high), the core must have formed hot, and the silicate mantle must be able to cool rapidly (i.e.  it must have a viscosity consistent with wet olivine).  If any of these criterion are not met magnetic field production fails.  These results contrast with previous workers who find that compositional convection can drive a core dynamo under a broad range of conditions.2Speaking of Mercury, which is slightly smaller than Ganymede, Dr. D. Russell Humphreys celebrated a confirmed prediction in the current Journal of Creation:Mercury’s magnetic field matches the measurements from the MESSENGER spacecraft (07/09/2008).  He adds this to his list of predictive successes for the magnetic fields of the outer planets.  Humphreys’ model assumes that magnetic fields are young – thousands of years old, not billions.1.  Bland, Showman and Tobie, “The production of Ganymede’s magnetic field,” Icarus 198 (Dec 2008), pp. 384�399, doi:10.1016/j.icarus.2008.07.011.2.  reference cited by Bland et al: S.A. Hauck, J.M. Aurnou and A.J. Dombard, “Sulfur’s impact on core evolution and magnetic field generation on Ganymede,” J. Geophys. Res. 111 (2006) 10.1029/2005JE002557 E09008.And so another phenomenon doesn’t fit the consensus view of the age of the solar system.  Creationists who think they are escaping difficulties by accepting the consensus age are merely trading one set of problems for another.  Every view has problems; face it.  But don’t think the long-age evolutionary naturalistic view is simple and straightforward.  When they pile on miracles needed to get their physicalist scenarios to work, then the appeal to miracles becomes academic: do you want purposeful miracles, or miracles of chance?  Like ketchup with fries, miracles go better with design.    This paper does not support a view that Ganymede is a few thousand years old, of course, but neither does it rule it out.  What it does, though, is put plausible upper limits on the age of Ganymede, beyond which appeals to highly contrived special conditions are required.    Reconstructing the core history of Ganymede can only be done with scientific models.  Being simulations with simplifying assumptions, models can only be judged by subjective criteria of plausibility.  If you think that it is plausible to insert special conditions to form Mercury, Venus, Earth, the moon, Mars, Jupiter, Io, Europa, Ganymede, Callisto (which has an induced magnetic field), Jupiter’s gossamer rings, Saturn, the F-ring, the A-ring, the C-ring, the D-ring, Enceladus, Rhea, Titan, Hyperion, Iapetus, Uranus, the rings of Uranus, Miranda, Neptune, the rings of Neptune, Triton, comets, binary asteroids and the Sun-Earth diameter, then be our guest.  Just admit that you are, in effect, applying your own intelligent design to imaginary models of reality, not to reality itself.(Visited 15 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

7 DIY Filmmaking Techniques Using the Versatile Wheelchair Dolly

first_imgThe wheelchair dolly is a tried-and-true DIY tool — for projects of all sizes. Check out these 7 tips on how to use one to improve your film.Cover Image of Jean-Luc Godard on the set of Breathless (via Studio Canal).There are plenty of dolly options available for filmmakers at all levels of production. Even for those looking for DIY options can find tons of great resources to put something together on the cheap. However, if you’re looking for one simple solution (which can actually be much more versatile and fun), consider the indie-filmmaker’s favorite — the wheelchair dolly.While there are some wheelchair-style dollies specifically for filmmaking (all great options), let’s focus on using a standard-issue wheelchair, which you can often find secondhand at thrift stores or online (here’s a link to Ebay). Once you’re all set, here are seven creative ways to put your DIY wheelchair dolly to use.1. Push or PullImage via AMC.Let’s start with the basics. Using a wheelchair dolly is great for pushing in or pulling out shots. You’ll usually see these types of shots in large-scale productions, as they both see a lot of use for narrative effect (creating important moments) or for clarity of composition. If you keep the movement short and straight, the wheelchair will work very much like your standard track-dolly setup, but without all the assembly and breakdown.Bonus Tip: if you’re shooting solo or with an extremely small crew, you can always sit yourself in a wheelchair and do some short push or pull movements using only your feet. Try it — even a few inches can add style and depth to what would normally be a regular set shot.2. Walk and TalksImage from The West Wing via NBC.Along with straightforward push and pull shots for dramatic effect, a wheelchair is a great option for long tracking shots like the now-recognizable Aaron Sorkin-style Walk and Talk shot (which you can see parodied here). The wheelchair is great because your camera operator can face your subject or subjects while someone pulls them backward.3. Tracking Low AnglesImage via Tumblr.The flexibility a wheelchair offers to the camera operator while sitting is also great. You usually won’t need to lock the camera operator in, and they’ll have almost a full range of motion from the seat. As such, to get many low-angle tracking shots, you don’t need to assemble a tricky low-to-the-the floor dolly setup; you can simply direct your camera op to lean over and hold the camera at a low angle. This may make things a little less steady, but for shorter moves (and with surer-handed ops), it’s a solid technique.4. Curved Tracking MovesAnother aspect of the wheelchair dolly that makes it unique is the simple fact that it is not bound to a set of tracks. The wheelchair, by its nature, is more mobile and can perform complex and curved maneuvers. Try laying some track to recreate this famous circle move from Jean-Luc Godard’s French New Wave classic Breathless.5. Extremely Long Tracking ShotsImage via monnomestdavid.Similar to the Walk and Talk trick, using a wheelchair dolly for extremely long tracking shots is a great way to consolidate resources on DIY productions. The wheelchair can be quite effective, even with only a two-person crew: one to sit and one to move the wheelchair around. If you’re going over long distances, try situating your camera operator in a more relaxed and flexible position (they can also use a Steadicam or some other stabilizer). Be careful, though, with different floor textures (like thick carpet), thresholds between doorways, etc.6. Dolly ZoomsThe wheelchair dolly can also make it easier to perform dolly zooms (which is also known as the Hitchcock zoom or Vertigo Effect). With the camera operator sitting (or kneeling), their hands should be free enough to manually perform a zoom while someone pushes them in the chair at a medium to fast pace. You may have to do several takes, as hitting the focus will always be difficult during such a move, but the effort is worth it in the end.7. Using Natural GravityImage via Film Riot.Finally, one of the riskier wheelchair dolly tricks is to let things like gravity and inclines take control of your movements. These opportunities might not come up often, but if you ever need to simulate a character POV or follow a movement that rapidly increases in speed while slipping or sliding down, using a wheelchair in a controlled free fall move is a daring option. (Be sure to have plenty of people around to help guide and catch the camera op.)For more DIY production tips, check out some of these resources.Gear Hacks: DIY Camera Stabilizers and Rigs for Under $255 DIY Tutorials and Gear Hacks for Filmmakers5 DIY Tips for Your Next ShootPremiumBeat DIY ArchivesThree Ways To Light A Tent Scene On a Low Budgetlast_img read more

DLF raises Rs 3173 cr via QIP

first_imgNew Delhi: Mar 29 (PTI) Realty major DLF Friday said it has raised Rs 3,173 crore by selling shares to institutional investors through its QIP offer. DLF, the country’s largest real estate firm in market value, would utilise this amount mainly to prepay debt, which stood at around Rs 7,000 crore at the end of December 2018. On Monday, the company had launched its qualified institutional placement (QIP) issue, offering up to 17.3 crore shares to investors. The issue closed Thursday. In a regulatory filing, DLF Friday informed that the Securities Issuance Committee has approved the allotment of 17.3 crore equity shares to eligible qualified institutional buyers at an issue price of Rs 183.40 per share, aggregating to about Rs 3,172.82 crore. Sources on Tuesday had said that DLF’s QIP issue has been oversubscribed by two times, enabling the company to raise around Rs 3,200 crore. Major institutional investors who participated in QIP offer include Oppenheimer, UBS, HSBC, Marshall & Wace, Myriad, Key Square, Goldman Sachs, Indus, Eastbridge, Tata Mutual Fund and HDFC Mutual Fund, sources had said. This is the third major fundraising from DLF. In 2007, DLF raised about Rs 9,200 crore through an initial public offering (IPO). In 2013, the company had raised nearly Rs 1,900 crore through an institutional placement programme. Meanwhile, the committee Friday also approved the conversion of 24.97 crore compulsory convertible debentures (CCDs) issued to promoters entities into equal number of equity shares at Rs 217.25 per share. In December 2017, the company’s board had allotted on preferential basis 37.97 crore CCDs and nearly 13.81 crore warrants to promoters entities against their infusion of funds in DLF. DLF’s group Chief Financial Officer Ashok Tyagi recently said the QIP proceeds and further infusion of Rs 2,500 crore from promoters against the issue of warrants would help the company to significantly reduce its debt. DLF promoters K P Singh and family have already infused Rs 9,000 crore in the company and would pump in Rs 2,250 crore more. In lieu of this fund, DLF had issued CCDs and warrants to the promoters. As infusion of the fund by promoters could have led to an increase in their shareholdings beyond permissible limit of 75 per cent, the company planned QIP to maintain minimum public shareholding of 25 per cent in a listed entity. In August 2017, the promoters had sold the entire 40 per cent stake in rental arm DLF Cyber City Developers Ltd (DCCDL) for Rs 11,900 crore and infused bulk of this amount in the company to cut net debt.last_img read more

9 injured after train collides with inspection car

first_imgKolkata: Nine persons reportedly suffered injuries after a local train collided with a railway inspection car at Sreerampore Station on Saturday afternoon. Locals and railway staff rescued the injured and rushed them to a local hospital.According to passengers waiting at the station, a railway inspection car was working on the track. At the same time, Seoraphuli local train was to arrive availing the same track. The locomotive pilot of Seoraphuli local identified the inspection car at a close distance. As soon as he saw the inspection car, he applied brakes. But before it could come to a complete halt, the train hit the inspection car resulting in serious damage. Also, the staff in the inspection car sustained injuries due to the collision. Also Read – Bengal family worships Muslim girl as Goddess Durga in Kumari PujaSome passengers of the Seoraphuli local train also sustained minor injuries due to the collision as they fell on the compartment floor when there was a jerk. However, because of the slow speed of the train, the extent of damage was not high. Sources informed that the locomotive pilot of Seoraphuili local was given a green signal to avail the said track to proceed. Questions arose as to how could a train get clearance along the same track where an inspection car is already there. According to railway sources, an investigation in this regard has been ordered already. If any negligence is found, stringent action will be taken.last_img read more

AI robots could assist soldiers in future Study

first_imgWashington: Scientists in the US are developing artificial intelligence (AI) systems that could help robots assist soldiers in the battlefield in future. For the research, published in the journal Science Advances, team looked at soldier brain activity during specific tasks for ways to incorporate AI teaming to dynamically complete tasks. According to Jean Vettel, a senior neuroscientist at the Army Research Laboratory (ARL) in the US, technologies that can predict states and behaviours of the individual soldier may help create a more optimised team. Also Read – Saudi Crown Prince ‘snubbed’ Pak PM, recalled jet from USThe work between ARL and the University at Buffalo is looking at ways the dynamics and architecture of the human brain may be coordinated to predict such behaviors and consequently optimize team performance. “In military operations, soldiers perform multiple tasks at once. They’re analysing information from multiple sources, navigating environments while simultaneously assessing threats, sharing situational awareness, and communicating with a distributed team,” said Vettel. Also Read – Record number of 35 candidates in fray for SL Presidential polls”This requires soldiers to constantly switch among these tasks, which means that the brain is also rapidly shifting among the different brain regions needed for these different tasks,” he said. “If we can use brain data in the moment to indicate what task they’re doing, AI could dynamically respond and adapt to assist the Soldier in completing the task,” he added. To achieve this future capability, the researchers first sought to understand how the brain coordinates its different regions while executing a particular task. They used a computational approach to understand how this may be characterised to inform the behavioral prediction. To complete the study, researchers mapped how different regions of the brain were connected to one another in 30 different people via tracts of tissue called white matter. Scientists converted these maps into computational models of each subject’s brain, and used computers to simulate what would happen when a single region of a person’s brain was stimulated. They then used a mathematical framework, which they developed, to measure how brain activity became synchronised across various cognitive systems in the simulations. “While the work has been deployed on individual brains of a finite brain structure, it would be very interesting to see if coordination of Soldiers and autonomous systems may also be described with this method, too,” said Javier Garcia, an ARL neuroscientist. “Much how the brain coordinates regions that carry out specific functions, you can think of how this method may describe coordinated teams of individuals and autonomous systems of varied skills work together to complete a mission,” Garcia said.last_img read more

Get ready for theatre relay

first_imgAlong day theatre festival, ‘Thespis 3’ – the third season of the National Micro Drama Festival will be organised by Vriksh the theatre, for the theatre lovers on April 21, at Kamani Auditorium.It is going to be the first time in the history of world theatre that forty plays will be performed on a single day with a maximum duration of ten minutes and awards are offered for 10 categories like Best Production, Script, Direction, Actor, Actress, Technician, will also be given. The event will be inaugurated by ‘Kanpur- e- Kashmir’ directed by Vijay Kapoor, the winner of last year. Further the festival would be followed by plays in English, Hindi, Bengali, Malayalam, Urdu including ‘Hukum Malik’ by Rajiv Kohli; ‘Chand Ka Pinjra’ by Deepu Sood; ‘Natrang’ by Sumit Nair, ‘The Red String café’ by Pratibha and Ananya Sharma; ‘Shatabdir Byadhi’ by Prithwijit Chowdhury; ‘Aattam’ by M Shaji, to name a few. This year’s objective of the theatre group is to spread the idea of ‘Art for Humanity’, through different plays, different stories which will be shown. The festival has been organised from three years, in the name of Greek artist ‘Thespis’ – who is believed to be the person first to appear on stage. Not only the festival has entertained the audience, but also to its credit, this celebration of abundance has also bagged ‘Best of India Records’ for the last two consecutive years. Due to its unique nature, questions related to this festival have found a way into competitive examinations for bank recruitments and Civil Service prelims preliminary.last_img read more

Kansas — with a 28-4 record from a very good Big 12 conference — might seem like a no-brainer No. 1 seed. But other than Elo, the computer ratings are a bit down on the Jayhawks, noting that they won many games by narrow margins that could reflect luck as much as clutch performance. Still, they’re the favorite here. Louisville is a perfectly adequate No. 2 seed, but they have to survive a difficult Round of 32 game — both No. 7 Michigan and No. 10 Oklahoma State are underseeded. And the regional finals will be played in Kansas City, advantaging KU.A lot of people are also pointing toward Kansas’s Round of 32 matchup — against either No. 8 Miami or No. 9 Michigan State — as a difficult spot. But as much as it pains me to say this as an East Lansingite, I’m not sure this is Michigan State’s year. They’ve won only five road or neutral-site games all year, and while a lot of credit should be given to the Spartans for how many tough teams they scheduled, they also didn’t come away with a lot of wins. Then again, Tom Izzo has made a fool of everyone else’s best-laid plans and projections in the past.No. 3 seed Oregon is another case of a team that might seem to be underseeded but probably isn’t. They lost senior forward Chris Boucher to an ACL tear in the Pac-12 tournament, substantially weakening their front-court depth. 3Baylor1913161717201228 11Kansas State5129313228344636 ELO = FiveThirtyEight’s Elo rating; POM = Ken Pomeroy; SAG = Jeff Sagarin “predictor” rating; BPI = ESPN’s basketball power index; MOOR = Sonny Moore power ratings; NCAA = Selection committee’s 68-team “S-Curve”; PRE = Composite of preseason rankings 1Gonzaga711212412 FiveThirtyEight’s March Madness predictions are up and ready for your perusal. But while we’re really excited about the tournament, we have to say this is not a year in which we’re going to be able to help you all that much, at least in the Elite Eight and beyond.That’s because there’s as much parity in the tournament as there’s ever been — not necessarily from the very top of the field to the very bottom, but certainly among a group of No. 1 and No. 2 seeds that aren’t all that easy to distinguish from one another. Meanwhile, the blue bloods have to navigate a minefield of underseeded teams such as Wichita State and SMU, with some having more perilous paths than others.The one team that potentially stood out from the pack — defending national champion and No. 1 overall seed Villanova — has been undermined by a difficult draw. While the Wildcats are still the nominal favorite to win the tournament, they have only a 15 percent chance of doing so, which is tied for the lowest probability for a frontrunner in our seven years of making tournament predictions.1Fourth-seeded Louisville also had a 15 percent chance in 2014.Our methodology for making these projections is exactly the same as it was last year. They’re based on a blend of six computer rankings: FiveThirtyEight’s Elo ratings, Ken Pomeroy’s ratings, Jeff Sagarin’s “predictor” ratings, ESPN’s BPI, Joel Sokol’s LRMC ratings and Sonny Moore’s computer power ratings. We also use two human-generated rating systems: the selection committee’s 68-team “S-Curve” and a composite of preseason ratings from coaches and media polls. The preseason ratings have some predictive power when used carefully, serving as a hedge against teams that may have overachieved or underachieved relative to their talent level and are due to revert to the mean.VIDEO: A No. 16 seed will win, but don’t bet on it ELO = FiveThirtyEight’s Elo rating; POM = Ken Pomeroy; SAG = Jeff Sagarin “predictor” rating; BPI = ESPN’s basketball power index; MOOR = Sonny Moore power ratings; NCAA = Selection committee’s 68-team “S-Curve”; PRE = Composite of preseason rankings 10Okla.

That’s important to keep in mind, because travel can be a big factor in the West region, with teams potentially flying a long way to play games in an unfamiliar time zone.Otherwise, the West is a bit … weird. For one thing, Gonzaga — with a 32-1 record largely assembled outside a top conference — isn’t an easy team to get a handle on. A few of the computer ratings have the ‘Zags as the No. 1 overall team, while the committee’s rankings — and Elo — are more skeptical of them because they beat up on middling opposition. No. 2 Arizona, meanwhile, isn’t well liked by the computers, with its strength of schedule not as good as you’d expect from a 30-4 Pac-12 champion. Michigan State, whom the Wildcats beat to start their season, was Arizona’s best nonconference win.West Virginia, the No. 4 seed, is another highly divisive team. They lost eight games but those losses came by an average of just 4.6 points, so the computer formulas think they’re badly underseeded. It’s a tough break for the Mountaineers to not only have drawn Gonzaga in the Round of 16 but also to have to fly across the country to play the game.The West also features a number of potential spoilers from strong academic schools — Northwestern, Princeton, Vanderbilt — that will probably create a lot of buzz if they win. (All those Northwestern journalism grads won’t hurt.) None of those teams are especially underseeded, however. A better dark-horse pick is No. 7 St. Mary’s, which could give Arizona fits in the Round of 32.Check out our March Madness predictions.

Working in the Tar Heels’ favor: they played one of the toughest schedules in memory, rank slightly ahead of Kentucky in most of the computer rankings (although not in Elo) and are on the opposite side of the bracket from Wichita State, which was ridiculously underseeded. (The Shockers ranked in the top 10 overall according to two computer rankings, LRMC and Pomeroy, and yet they are just a No. 10 seed in their region according to the committee.) Helping Kentucky: the Wildcats are a bit healthier than UNC, come in hotter (having won 11 games in a row and the SEC tournament), might have a bit more top-level talent (as reflected in their preseason ranking) and the location of the regional final, in Memphis, could be slightly favorable to them.If it’s not UNC or Kentucky, the obvious alternative to emerge from the South is No. 3 UCLA, but the various computer rankings are not as bullish on the Pac-12 as the conventional wisdom seems to be. The South also features perhaps the best bet for a 5-vs-12 upset: No. 12 Middle Tennessee, which knocked off Michigan State last year, has a roughly 50-50 shot of beating No. 5 Minnesota, according to our forecast. 3UCLA1418141413161115 15Troy5558605759586065 How the teams compare: East region ELO = FiveThirtyEight’s Elo rating; POM = Ken Pomeroy; SAG = Jeff Sagarin “predictor” rating; BPI = ESPN’s basketball power index; MOOR = Sonny Moore power ratings; NCAA = Selection committee’s 68-team “S-Curve”; PRE = Composite of preseason rankings 4Purdue1815121112131614 12Mid.

But it got absolutely no help from the committee, who stuffed the East region with tough teams. Duke — which began as the preseason No. 1, slumped in the middle of the season, and then recovered to win the ACC tournament this weekend — engenders some disagreement among the various ratings systems but is no pushover as No. 2 seed, to say the least. That sets up a possible grudge match between Villanova and Duke, the past two tournament champions, in the East regional final at Madison Square Garden.But Villanova has their work cut out to get there. Wisconsin, the No. 8 seed and ‘Nova’s potential opponent in the Round of 32, should have been seeded several slots higher according to the computers and has a history of tough postseason play. No. 4 Florida and No. 5 Virginia also get a lot more respect from the computers than they did from the committee, with blemished win-loss records masking difficult schedules and strong defenses.On Duke’s side of the bracket, No. 6 SMU could be a tough out and is about even-money in its potential Round of 32 matchup against No. 3 Baylor. But if you’re looking for a first-round upset, there aren’t any slam-dunk candidates.

How the Spurs Boxed in Kevin Durant

As the San Antonio Spurs took the Oklahoma City Thunder apart Thursday night on their way to winning Game 5 by 28 points, Thunder forward Kevin Durant quietly battled to finish with 25 points. That’s nothing to sneeze at, but it’s still short of the sparkling numbers he had been putting up before the NBA’s Western Conference finals began.Through the first two rounds of the playoffs, Durant had been magnificent, averaging 31.4 points per game and hitting the 30-point mark in nine of 13 games. In the five games against the Spurs, Durant has hit the 30-point mark just once, and in the Thunder’s three blowout losses, he’s averaged just 22.7 points.Durant’s efficiency has also suffered. His shooting accuracy from different areas of the floor hasn’t been significantly different, but the Spurs have forced him away from his preferred spots. Shot location statistics from NBA.com show how the distribution of his true shot attempts has changed in these games (true shot attempts include field goal attempts and trips to the free-throw line, essentially all non-turnover possessions).Kevin Durant’s Distribution of True Shot AttemptsIn the Thunder’s three losses against the Spurs, far fewer of Durant’s true shooting attempts have come around the basket. Durant has been pushed back into the inefficient mid-range zone.This may seem like splitting hairs; we’re talking about a potent scorer from anywhere on the floor. But even a great scorer like Durant is much more efficient in some areas. For example, during the regular season, a Durant trip to the free-throw line had an expected value more than twice that of one of his mid-range jump shots.In fact, if we give Durant his shooting percentage from the regular season but his shot selection from the three losses against the Spurs, Durant would have a true shooting percentage of 54.4. That’s far less his 63.5 regular-season number, which ranked second in the league this season and was the best in NBA history by a player who used at least 32 percent or more of his team’s offensive possessions.Defensive pressure usually conjures images of blocked shots and steals. But by making Durant change his shot selection, the Spurs’ defense turned an elite scorer into merely a good one. read more
