first_imgPHOENIX — For the highlight shows featuring the NBA’s latest gaffes, look no further than the past few Lakers games.Kobe Bryant threw the ball five rows into the stands. Nick Young lobbed a shot that didn’t even hit the rim. Xavier Henry dribbled behind his back, only for the ball to brush off his foot and roll out of bounds. “Dumb moves and dumb errors,” Lakers center Chris Kaman recently said.And they partly explain why the Lakers (13-14) enter tonight’s game against the Phoenix Suns (16-10) at US Airways Center averaging 15.6 turnovers per contest through 10 games in December, the seventh worst mark out of 30 NBA teams. Long-term injuries to Steve Nash (nerve issues in back), Steve Blake (hyperextended right elbow) and Jordan Farmar (strained left hamstring) have left the Lakers without a true point guard for the past five games. Before he fractured his left knee and became sidelined for the next six weeks, Bryant averaged 5.7 turnovers in six games after spending the previous eight months healing his left Achilles tendon.The Lakers have also listed Pau Gasol as day-to-day tonight against Phoenix because of a respiratory illness, potentially leaving the Lakers without any playmakers for the second consecutive game.“We’re not used to being point guards in this league,” Lakers forward Young said. “I haven’t really been a point guard in bringing the ball up. I bring it up on fast breaks, but that’s about it. We got to get comfortable.”Farmar could return when the Lakers host the Miami Heat on Christmas Day, but the timelines for Nash (three weeks) and Blake (five) seem distant. The Lakers’ 24 turnovers in a loss against Golden State on Saturday tied a season high. In the past two games, the Lakers’ ball-handling has mostly diminished when Young (4.5 turnovers) or Henry (three turnovers) mans the point. It didn’t help that Kendall Marshall’s debut with the Lakers against the Warriors entailed four turnovers in only five minutes. “We don’t make excuses. Those guys are very important to our team, but we should look at it as an opportunity for the other guys to step up,” said Lakers guard Jodie Meeks, who also posted four turnovers Saturday against Golden State. “We’re good players and we have some new guys to help out. We have to be ready for everything.”When it comes to handling the ball, the Lakers have shown that remains easier said than done. Lineup shuffleChris Kaman has gone from sitting out of games completely to ascending into the starting lineup.That might happen again should Gasol sit out against Phoenix. But after Kaman played in two consecutive games following a string of missed appearances in 12 of the past 13 contests, Lakers coach Mike D’Antoni said “he’s going to play some.”Kaman has averaged 8.3 points on 47.2 percent shooting and 5.7 rebounds in 17.5 minutes through 15 games. But aside from Kaman’s back spasms, D’Antoni sat him because of his preference for a stronger interior defender (Jordan Hill, Robert Sacre) or a smaller forward (Shawne Williams). “It’s a numbers thing,” D’Antoni said. ”It has nothing to do with players. You look and see who plays well with each other and try to figure it out.”center_img Newsroom GuidelinesNews TipsContact UsReport an Errorlast_img read more

center_img Citation: Physicists Propose a Method to Observe Dirac Monopoles (2009, July 28) retrieved 18 August 2019 from https://phys.org/news/2009-07-physicists-method-dirac-monopoles.html Ville Pietilä and Mikko Möttönen, both of the Helsinki University of Technology in Finland and the University of New South Wales in Australia, have published their theoretical demonstration in a recent issue of Physical Review Letters. Here, they explain how applying an external magnetic field to a Bose-Einstein condensate (BEC) – a large group of cold atoms that exhibits coherent quantum properties – can create point-like topological defects on the spin texture of the BEC. These defects give rise to a vorticity field that is essentially equivalent to the magnetic field of a magnetic monopole.“Since all experimental attempts to find magnetic monopoles have proven to be futile, there is no experimental evidence supporting the existence of magnetic monopoles,” Pietilä told PhysOrg.com. “Other types of monopoles without the Dirac string have been realized in experiments already in the early ‘90s in liquid crystals. An analogy of the real space magnetic monopole was reported to occur in the crystal momentum space of a metallic ferromagnet, but the experimental evidence in this case is somewhat indirect. Dirac monopoles in the more general settings are predicted to occur in various systems such as superfluid Helium-3 and dilute spin-1 Bose-Einstein condensate but so far there are no (direct) experimental observations although they may have been present in some of the Helium-3 experiments. There is also a very recent suggestion on how to induce a magnetic monopole to a band insulator.“Since magnetic monopoles have never been observed, it is pertinent to ask whether there is something unphysical in the whole concept,” he continued. “Our work shows that at least the Dirac monopole can be realized experimentally, thus indicating that it is more than just a theoretical curiosity. However, it should be stressed that our work does not tell anything about the existence of magnetic monopoles in the electromagnetic field.”Pietilä and Möttönen predict that it should be possible to design an experiment to detect the monopole in this situation, if it does exist. As they explain, the magnetic field of the monopole is provided by a Dirac string, which is a line extending from the monopole to infinity. The Dirac string explains why the monopole charge comes in discrete quanta. Since the Dirac string carries two quanta of angular momentum, it is expected to be prone to splitting into two separate strings, each carrying a single quantum.

first_imgYesterday, the team at Ionic released the final candidate version for Ionic v4. The final version of Ionic v4 is expected to be released in early 2019. Ionic is the app platform for web developers for building mobile, web, and desktop apps with one shared code base and open web standards. Ionic v4 RC has been nicknamed Ionic Neutronium following the earlier RC versions Ionic 4.1 Hydrogen, Ionic 4.2 Helium, 4.3 Lithium, etc. With the final release candidate, the API has now been stabilized along with fixing patch and minor releases. Improvements in  Ionic v4 RC? Mobile performance Ionic v4 will come with improvement in app startup times, especially on mobile devices. It comes with smaller file sizes that work well with apps on iOS, Android, Electron, and PWAs.                                                       Source: Ionic Ivy Renderer for Angular users Ionic v4 will be shipped with Angular Ivy Renderer. It is Angular’s fastest and smallest renderer so far and will prove to be useful for Angular and Ionic developers. Interestingly, even a simple Ivy “Hello World” app reduces down to a size of 2.7kb. UI Library Distribution Ionic Neutronium has made improvements to the UI library. It features the use of standard Web APIs like custom elements that are capable of lazy-loading themselves on-demand. Now both Angular and Ionic can iterate and improve independently, and developers can take advantage of these improvements with fewer restrictions. Support for Angular tooling Angular CLI and Router both have become production ready with this release and are  capable of native-style navigation required by Ionic apps. This release also comes with an added support for Angular schematics, so Angular developers can run ng add @ionic/angular to add Ionic directly to their app. Angular, React, and Vue Ionic v4 RC allows users to continue using Ionic in their projects based on React or Vue. The goal behind this release was to decouple Ionic from any specific version of one single framework’s runtime and component model. Last month, Ionic community and Modus Create released the alpha version of @ionic/vue. @ionic/ react is in progress and is expected to release soon. Major bug fixes The issues with scrollable options have been fixed. The Cordova browser error has been fixed. Fixes have been made to sibling router-outlets and router-outlet memory. There is an improvement in progress-bar as it looks better now. Issues with virtual-scroll have been fixed. Many users are happy with this release and awaiting the final version in 2019. This might prove to be the perfect new year celebration for the developers as well as the Ionic team. Read more about this releases on Ionic’s blog post.
