BJP mum after Karnataka CM Siddaramaiah unveils state flag

first_imgIn a move seen by many as a masterstroke by Karnataka CM Siddaramaiah to silence the Opposition on issues like deteriorating law and order and attack on the Lokayukta, the state government unveiled the new state flag on Thursday.This was proposed and designed by the 9-member committee which was constituted in 2017. Siddaramaiah met a delegation of pro-Kannada activists who initially were not happy with the change in the design but have now given their nod.Sa Ra Govindu, President, Karnataka Film Chambers of Commerce was elated with the decision taken by the CM.He said, “We are all happy with the CM’s decision and so are the citizens of Karnataka.”The new flag is a tricolour – yellow, white and red.It also sports the ‘ganda bherunda’ or the two headed eagle in the middle. The flag committee at the meeting explained the meaning of the colours to the activists and writers.Yellow stands for forgiveness, white for peace and red for bravery along with the state emblem.On the white, there is the Sarnath lion and below it is a shield with the ganda bherunda. On either sides are two lion-elephants – a mythological 8-legged creature possessing the strength of lions and elephants combined.The committee decided not to use the unofficial yellow and red flag that has been in vogue since the 1960s. It was Kannada writer and activists MA Ramamurthy who designed the first flag for a political party. Since then it has been used by various pro-Kannada organisations as a symbol of cultural pride.advertisementThe committee has informed the CM that there is no provision in the Constitution that disallows states from having their own flags.The CM while addressing the media said, “Now that there are no hurdles, the recommendation will be sent to the Government of India”.Taking a dig at the BJP which has decided to stay mum on the issue, he added, “I am hoping that the BJP will tell the Centre to get this work done quickly with all the required approvals.”The Congress has understood that it would be tough for the BJP to oppose such a move that is seen as Kannada pride by many. Along with the fight against Hindi imposition, this new flag has put the BJP in a quandary.The BJP in the state has for now decided to stay away from commenting on the Karnataka flag.Last year, when the committee was set up, many leaders lambasted the CM saying the move is against the integrity of the country. They stated that the BJP always fought for one nation, one flag.But after receiving flak from the citizens of the state then, this time they have decided to not say anything lest they offend either their party high command or the people of the state.Exclusive: Siddaramaiah on Cauvery verdict, farmer suicides, Karnataka elections and morelast_img read more

New Brunswick Tories prepare for power after Liberal government falls

first_imgFREDERICTON – Five weeks after New Brunswickers went to the polls, Tory Leader Blaine Higgs has become the premier-designate — and is promising to move quickly.“People of the province should feel comfortable that the system worked, it just took a little longer,” Higgs said after meeting with Lt.-Gov. Jocelyne Roy Vienneau late Friday, hours after Brian Gallant’s Liberals fell on a confidence vote.She asked if the Progressive Conservative leader had the confidence to form government, and Higgs said he told her that he did.Afterward, Higgs struck an optimistic tone as he spoke to reporters.“I guess the next step begins,” Higgs said.“I believe our province can be in first place in all categories. And I believe that opportunity is right before us today.”Gallant, whose government fell when the legislature voted against the throne speech, said he was unsure about his own political future, but he wished the Tories luck.“Their success will be New Brunswick’s success,” he said.Higgs said he wants the transition to occur as quickly as possible, with a cabinet by late next week and a throne speech before the end of the month.“The throne speech won’t be a shopping list. It will be a priority list and it will be focused on some big items we can agree on,” Higgs said.“We will set lofty goals and achieve them. We don’t need more taxes, we need results.”The Tories won 22 seats in the September election — one more than the Liberals — while the Greens and People’s Alliance each won three seats.Gallant sought to survive with a minority government by adding many of the opposition’s campaign promises to his party’s throne speech earlier this week, but his party’s fate was sealed Thursday when both the Tories and People’s Alliance said they’d vote to defeat it.Higgs said he believes his minority government can survive four years by producing results.Its success will depend on support from the opposition parties, and that has thrown the spotlight on language rights in Canada’s only official bilingual province.Higgs said Friday his priority would be to address a shortage of paramedics, where the failure to meet language requirements has left some ambulances unstaffed.He said francophones should not be concerned by his government’s approach.“They shouldn’t be worried at all. They should be grateful that we’re going to provide the health care they demand all across the province as an interim measure to meet the language requirements that we have,” he said.The People’s Alliance, which has agreed to prop up the Tories for at least 18 months, put bilingualism and service duality front and centre in their campaign.Gallant said Friday it was important parties don’t use the issue as a “political weapon.”He said it appeared the election results — which saw the Liberals dominate the largely francophone north and the Tories and People’s Alliance do better in the mostly anglophone south — suggested the province is divided along regional and linguistic lines.But he said people should not be taken in by those apparent divisions.“What binds us together is greater than what drives us apart … We’re all New Brunswickers.”Gallant said he wished he had done more to promote unity and bilingualism.“I will not pretend that we were a perfect government, but we were a good government.”People’s Alliance Leader Kris Austin said his party has agreed to support the Tories to provide some stability to the legislature.However, he said his members will be free to vote their conscience on bills.“We are in nobody’s back pocket, but in a minority government you do have to work together and we’ve agreed to do that with Mr. Higgs,” Austin said.Austin said his first priority is to get the new Tory government to address the ambulance issue.Green Leader David Coon and his two members voted to support the Liberal throne speech, which included many of his party’s campaign promises.“Our message to the Conservatives is that it’s important that they include those things in their throne speech, and we’ll be working hard to make sure that happens,” Coon said.Gallant said he and his wife are reflecting on what’s next — whether he serve as opposition leader or take a different path.“I still have a burning desire to make a difference, there’s no question about that,” he told reporters.last_img read more

Not Clear What Hoops DOD Needs to Jump through to Gain BRAC

first_imgIt’s no secret that most lawmakers are adamantly opposed to additional base closures and even after the Obama administration in February made its fourth request since 2012 for permission to hold a new BRAC round, it’s not clear that the Pentagon has made any headway with Congress.In fact, it’s difficult to find any lawmaker who will stand up for BRAC. In a story about the growing imbalance between DOD’s infrastructure and its force structure, Federal News Radio contacted six lawmakers who previously had said they would consider the department’s request to consolidate its infrastructure. None, however, agreed to comment for the story.During Capitol Hill hearings last month, John Conger, acting assistant secretary of defense for energy, installations and environment, acknowledged that Congress likely wouldn’t green light a new round unless the department updates the legislation authorizing a new round.“I think it goes without saying that there were a sufficient number of criticisms about the last BRAC round that Congress will want to have different authorizing legislation if they’re going to give us BRAC authority again,” Conger told the web site.What’s not clear is whether any members will take Conger up on his request for input on new legislation authorizing BRAC.DOD Comptroller Mike McCord told Federal News Radio that the department has been reluctant to recommend changes to the BRAC legislation over concerns that doing so would compromise the original spirit of the process.“When you start changing things, people assume you have a secret agenda and you’re trying to bias the process,” McCord said. “I think there’s some virtue in coming in with the same proposal every year and then trying to negotiate. Part of the problem is that we haven’t gotten an up-or-down vote on BRAC in many, many years. And failing to act on our proposal doesn’t give us any feedback on how to modify our proposal,” he said.

Android 23 Gingerbread expected in the next few days

first_img Tablet PC’s Getting Ready for Android 3.0 (PhysOrg.com) — While Google hasn’t made any official announcements on the release date for Android 2.3 several clues online over the weekend point to an imminent release of Gingerbread. This may have to do with the timing of iOS 4.2 which is set to release this week. Citation: Android 2.3 Gingerbread expected in the next few days (2010, November 9) retrieved 18 August 2019 from https://phys.org/news/2010-11-android-gingerbread-days.html Explore further It has been rumored that developers may receive Android 2.3 OTA update as early as November 11 for the Nexus One handset.center_img © 2010 PhysOrg.com Alvaro Fuentes Vasquez, a leader at the OHA organization that oversees development of Google’s Android platform, sent the follow tweet over the weekend: “Prepare your Nexus One (Developer Version) for Android OTA update 2.3 (Gingerbread) for the next few days.” It appears that the developers running the official developer handset, the Nexus One, will be the first to see their devices updated with Gingerbread. A few days after that, the build may get released to the general public who own a Nexus One. There has been no clarification on whether all Android 2.2 owners will get upgraded to Gingerbread or if it will start with Nexus One.The release of Gingerbread doesn’t mean that more powerful hardware is needed, as new features or optimizations can benefit users with existing handsets. Some of the rumored and/or expected changes include: • Big noticeable change to the OS is that the graphics and icons have been refreshed giving the application icons a more uniform appearance.• Large translucent icon place holders that will eventually be small for app menu. Customizable icon colors that are very vibrant and really changes the whole app UI. The refreshed UI also introduces motion scrolling to longer menus and adds animations.• SIP support to the native Google Voice application for Android that will make it possible to receive calls to your Google Voice number via Wi-Fi or 3G. This functionality may be only for Gingerbread and future releases.• The default media player would support more codecs by default at the OS Level and Google Music Service should be unveiled along with Android 2.3 as well as a separate market place for games are also expected with the new OS release.• Refreshed Android Market Web Site (for over-the-air app & music download)• Video Chat is gaining importance following Apple’s deployment of Face Time. • Social Network Enhancement and improvements of the core functionality like copy and paste to make it comparable with iOS.• WebM and WebP support in the browser (Open Standard Declaration)• Support for Google TV and bigger screen sizes up to a resolution of 1366×768.The OS update may be provided to Android developer handsets as early as this Thursday, November 11.

We’re also expanding the capabilities of the microscope to increase axial resolution through new hologram reconstruction algorithms and modifications of the microscope design.” Their goal is to study dynamics that have been too fast to be captured by current microscopy tools and better understand that relevant biological processes.

Copyright © PNAS, doi:10.1073/pnas.1306856110 Holograms set for greatness Bartels tells Phys.org that while laser scanning is the standard approach to imaging with nonlinear optical contrast, since the beams must be scanned 3D image update rates are limited – and the capture of fast dynamics are restricted to 1D or 2D images, or charting a trajectory through the specimen. “A major problem is that live specimen motion provides changes to the image that distort measurements and make it impossible to track high speed behaviors. On the other hand, SHG holography is a non-scanning technique that captures 3D information in a single shot for each volume image frame.”Bartels adds that in addition to neural circuit dynamics, the scientists are interested in observing the high speed dynamics of muscle contraction and connective tissues subjected to high speed stresses, and observing the resultant strains. “Current imaging techniques lack the ability to observe the effect of such trauma on tissues, as well as to follow the subsequent strains and relaxation or damage that occurs. SHG holography will be able to capture a time sequence of images from these tissues to better understand tissue properties. Moreover,” he continues, “SHG holography opens up imaging of dynamics that were previously not observable. As biological functions are determined by 3D organization in tissues, the ability to study high speed dynamics of biological functions – or the response of biological systems and tissues to rapid external stimuli, perturbations, or trauma – will expand our understanding of the biology, and may inform our ability to treat injuries.” © 2013 Phys.org.

Alternatively, kinetics of crystal formation and growth for some classes of crystals, including protein crystals, could be monitored.” (Phys.org) —In the world of biomedical science, optical microscopy rules – and nonlinear optical microscopy, which uses ultrashort pulse lasers as the illumination source, allows researchers to glean much greater detail from biological specimens. That being said, the technique’s weak signal levels significantly limit 3D image acquisition rates. Recently, however, scientists at Colorado State University employed 3D second harmonic generation achieved frame rates over 8,000 times faster than is possible with current nonlinear optical microscopy. (In second harmonic generation, or SHG, photons interact with a nonlinear material to form new photons with twice the energy and, therefore, twice the frequency and half the wavelength. While conventional optical microscopes obtain contrast by detecting variations in optical density, path length, or refractive index of the specimen, a second harmonic imaging microscope derives contrast from variations in a specimen’s ability to generate second harmonic light from incident laser light.) Moreover, the scientists introduced new methods that greatly improve the ability to quantify signal-to-noise quality. The researchers state that their study allows nonlinear optical imaging to study behavior that current experimental methodologies are unable to capture, such as neural circuit dynamics. 3D reconstructions of 350-μm thick mouse skeletal muscle at depths up to 150 μm.

(Scale bar: 10 μm.) Copyright © PNAS, doi:10.1073/pnas.1306856110 The main challenges in observing dynamics in live tissue, Bartels says, are the same as needed to speed up imaging to 10 mm/s – namely, brighter SHG scattering (which for a given specimen can only be increased by decreasing the illumination pulse duration) and optimizing the detection geometry. “While in this study we used a bulk ytterbium (Yb) solid state laser built in my laboratory that makes 350 femtoseconds laser pulses, we’re rebuilding the microscope with a new laser source that generates 80 fs pulses. This should increase our signals and top-end image field velocity by more than a factor of four. Also, it’s important to move the camera plane as close to the object as possible,” he points out, “as long as the fringes aren’t degraded by the moving objects.” The current paper provides a framework for evaluating an optimal experimental setup.

Prof. Randy A. Bartels discussed the paper that he, David R. Smith and David G. Winters published recently in Proceedings of the National Academy of Sciences. “Our current configuration is capable of imaging continuously at essentially 10 mm/s for bright enough objects,” Bartels tells Phys.org. “In general, the main challenge in achieving this is making sure that the fringes don’t wash out for a given velocity – and we provide theory to easily calculate these conditions, such that the configuration in this paper was capable of recording holograms of objects moving at this velocity. If we consider an object moving at 10 mm/s,” he explains, “then in a 1-ms integration time (which we can easily do continuously), we need to resolve an object displacement of ~ 10 micron, which is roughly twenty times our current imaging resolution.” Although faster imaging is possible for a bright enough object with the camera plane moved farther away from the image plane, he adds, the object scatter enough second harmonic light to form a good hologram – and while for any particular object this is limited by the hyperpolarizability of constituent harmonophores (molecules or particles that produce second harmonic generation), the researchers can increase brightness with shorter illumination pulses.”We’re already using SHG to observe endogenous harmonophores,” Bartels continues, and are now studying live dynamics of a number of processes such as muscle contractions in embryonic models, and dynamics of structural tissues such as tendons, under high strain rates.” The team is also taking beginning steps to image action potentials of neurons.
