ISS Suspended from US Navy Contracts

first_imgBack to overview,Home naval-today ISS Suspended from US Navy Contracts Industry news ISS Suspended from US Navy Contracts The US Navy has suspended Inchcape Shipping Services Holding Ltd. (ISS) and its affiliated companies from contracting with the Federal government.Rear Admiral John F. Kirby, Navy Chief of Information announced:“The suspension prevents Department of the Navy (DON) and all other Federal departments and agencies from entering into any new contracts, exercising options under existing contracts or issuing any new task or delivery orders under indefinite quantity contracts with ISS or its affiliates above the minimum guarantee during the period of suspension without agency head approval. ISS is a provider of husbanding services to the DON.The DON Acquisition Integrity Office recommended ISS’s suspension to the Suspension and Debarring Official (SDO), based upon evidence of conduct indicating questionable business integrity affecting ISS’s present responsibility to be a Government contractor. The SDO’s decision reinforces the high standards of conduct and business practices to which the DON holds contractors who desire to do business with the Federal government. It also reflects the mandate of the Secretary of the Navy, Ray Mabus, to ensure that DON contractors are fully compliant with contracting regulations and procedures.”[mappress]Press Release, November 28, 2013; Image: US Navycenter_img November 28, 2013 Share this articlelast_img read more

Who’s Your Daddy? Hunter Biden says, “It’s Not Me”

first_imgHunter Biden says he is not the father of a child born to a woman in Arkansas and he has agreed to take a paternity test to prove it.The birth of the child came while Hunter was in a relationship with Hallie Biden, his late brother Beau’s wife.Hunter, son of former Vice President Joe Biden, believes the results of the DNA test will prove he is not the father in time for a December hearing in Arkansas, according to court papers.Lunden Alexis Roberts, 28, filed a petition for paternity and child support against Hunter last May, claiming he’s the father of her baby, who was born in August 2018.She wants a court to establish that Hunter who is now at the center of Trump impeachment storm is the baby’s biological dad, and is seeking child support and health insurance for the now-14-month-old toddler.Hunter, 49, married Melissa Cohen two weeks before the petition was filed.

Giants ready to embrace ‘opener’ strategy, other alternative pitching methods

first_imgLAS VEGAS–As teams around baseball embraced a radical new pitching strategy in 2018, Giants manager Bruce Bochy was quick to voice his skepticism.Would Bochy consider using a reliever, or “opener,” to start a game and record just three outs before the Giants dipped into their bullpen? The longest-tenured manager in baseball didn’t exactly buy into the idea.Under new president of baseball operations Farhan Zaidi, Bochy will be asked to adapt.On the second day of Major League Baseball’s Winter …last_img read more

Fruit Flies Not Evolving

first_imgA long-running experiment trying to get fruit flies to evolve has failed.  A research team forced selection on the flies to explore the limits of natural selection.  Only minor changes were detected after 600 generations.  The research team was disappointed and surprised; there was even less evolution in these sexual organisms than in similar experiments with microbes, like bacteria and yeast (but see 07/12/2010).  And all this was under ideal lab conditions.  Success is even less likely in the wild.    The Editor’s summary of a paper in Nature was titled, “Experimental evolution reveals resistance to change” and ended that the authors “conclude that unconditionally advantageous alleles rarely arise, are associated with small net fitness gains, or cannot fix because selection coefficients change over time.”  Nature this week published the results of a 35-year study by UC Irvine and University of Southern California (USC).  Here is the abstract:1 Experimental evolution systems allow the genomic study of adaptation, and so far this has been done primarily in asexual systems with small genomes, such as bacteria and yeast.  Here we present whole-genome resequencing data from Drosophila melanogaster populations that have experienced over 600 generations of laboratory selection for accelerated development.  Flies in these selected populations develop from egg to adult ~20% faster than flies of ancestral control populations, and have evolved a number of other correlated phenotypes.  On the basis of 688,520 intermediate-frequency, high-quality single nucleotide polymorphisms, we identify several dozen genomic regions that show strong allele frequency differentiation between a pooled sample of five replicate populations selected for accelerated development and pooled controls.  On the basis of resequencing data from a single replicate population with accelerated development, as well as single nucleotide polymorphism data from individual flies from each replicate population, we infer little allele frequency differentiation between replicate populations within a selection treatment.  Signatures of selection are qualitatively different than what has been observed in asexual species; in our sexual populations, adaptation is not associated with ‘classic’ sweeps whereby newly arising, unconditionally advantageous mutations become fixed.  More parsimonious explanations include ‘incomplete’ sweep models, in which mutations have not had enough time to fix, and ‘soft’ sweep models, in which selection acts on pre-existing, common genetic variants.  We conclude that, at least for life history characters such as development time, unconditionally advantageous alleles rarely arise, are associated with small net fitness gains or cannot fix because selection coefficients change over time.In other words, they looked for evidence of a “selective sweep” – the signature of a beneficial mutation becoming fixed in the population – and could not find it.  They did the selection artificially, forcing the fly embryos to evolve toward faster embryonic development.  Despite lots of mutations, they found the flies resistant to change.  Not only that, the flies underwent “reverse evolution” – they said, “forward experimental evolution can often be completely reversed with these populations, which suggests that any soft sweeps in our experiment are incomplete and/or of small effect” (a soft sweep meaning selection is acting on standing variation instead of new mutations).  Possibly any beneficial mutations were hindered by linked deleterious alleles (canceling out the benefit) or antagonistic pleiotropy (in which one good mutation to a gene can cause one or more bad effects elsewhere).  Either way, the evolution is like one step forward, one or more steps back.    There was even more bad news for neo-Darwinian theory: the lab situation was more optimistic than the wild, where adaptive evolution is expected to occur.  You can get a lot of variation and mutation to appear in genomes, but no unconditionally beneficial mutations.  Their last paragraph expressed surprise at this, with a subtext of disappointment:Our work provides a new perspective on the genetic basis of adaptation.  Despite decades of sustained selection in relatively small, sexually reproducing laboratory populations, selection did not lead to the fixation of newly arising unconditionally advantageous alleles.  This is notable because in wild populations we expect the strength of natural selection to be less intense and the environment unlikely to remain constant for ~600 generations.  Consequently, the probability of fixation in wild populations should be even lower than its likelihood in these experiments.  This suggests that selection does not readily expunge genetic variation in sexual populations, a finding which in turn should motivate efforts to discover why this is seemingly the case.This experiment was begun in 1975.  After 35 years and 600 generations, accelerated by artificial selection, the net evolution (in terms of adaptation and improvement in fitness) was negligible if not nil.1.  Burke, Dunham et al, “Genome-wide analysis of a long-term evolution experiment with Drosophila,” Nature 467, 587-590 (30 September 2010); doi:10.1038/nature09352.Natural selection is always presumed to be the wonder-worker that can produce eyes, ears, sonar, flippers, jaws, hearts, and brains with its gradual, step-by-step improvement of natural variation, without design (07/20/2010, 05/04/2010).  OK, where is it?  It doesn’t work theoretically (09/28/2010, 06/11/2010, 03/21/2010, 03/17/2003), it doesn’t work rhetorically (04/17/2010), it doesn’t work historically (08/05/2010), and it doesn’t work experimentally (09/22/2010).  It doesn’t work in the lab, and it works less in the wild.  Unless you include “reverse evolution,” (06/26/2010), it doesn’t work at all.  Game over, Charlie (05/14/2010).  Stop the hype (08/13/2010).(Visited 218 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

What Is Panavision’s Liquid Crystal Neutral Density (LCND) Filter?

first_imgPanavision recently announced its brand-new LCND filter. We took a look at what it is, how it works, and what to expect from ND filters in the future.Neutral density (ND) filters are some of the most commonly used tools on any production. NDs use darkened glass to reduce the light that enters the lens, without affecting the color in the shot, allowing you to open the iris without overexposing the image.In cinema applications, ND filters slot into the mattebox and come in a variety of strengths, measured in decimals or fractions, which indicate the number of stops the by which the filter is reducing the light.In recent years, variable ND filters have seen widespread use for their ability to gradually adjust the intensity of the effect. However, this year Panavision has set out to up the ante with an entirely new variety of filter — an electronic ND.What Is Panavision’s LCND?At CineGear 2019, Panavision exhibited the final production model of its Liquid Crystal Neutral Density filter, or LCND. Teased at CineGear 2018, the LCND uses Liquid Crystal display technology, similar to that found in LCD screens to electronically dim incoming light to the lens.Panavision’s press release boasts clicked or ramped ND filtration from .3 ND to 1.8 ND — a full six stops at the click of a button. This is a first for Cinema NDs.The LCND contains no moving parts — you adjust the strength of the ND by applying voltage to the filter, which then brightens or darkens the glass. You control it with a dial on the side of the filter. Because of this, the LCND will only work in Panavision matteboxes, which side-load filters rather than top-loading them like other manufacturers.Image via Panavision.This was likely a design choice on Panavision’s part — you can’t buy Panavision gear; you can only rent it.The technology in the LCND is easily one of the most interesting developments in front-of-lens filters in a very long time. Unfortunately, it’s likely that only higher-echelon filmmakers will have access to the LCND due to Panavision’s rental-only business model.Let’s take a look at the tech behind electronically controlled NDs.Improving ND TechnologyImage via Panavision.As I mentioned earlier, variable neutral density filters have made quite the impact on the industry in the past decade. These variable NDs operate by stacking two polarizing filters with a rotating dial, which limits incoming light, depending on the orientation of both of the filters.While the LCND is a first for cinema, similar technologies have been in use in other sectors.High-end car and home window glass have made use of automatic tinting and hazing for some time now. This tech allows automatic tinting and hazing of the glass with the press of a button — or in automatic response to ambient light levels in similar ways to Panavision’s LCND.The LCND is the first front-of-lens filter to make use of these technological breakthroughs. But, in 2018, Sony implemented similar electronic NDs in recent Prosumer Video camera releases.Image via Sony.The PXW-X180, FS5, and FS7 II have built-in electronic Neutral Density filters, which may be clickable or variable depending on operator preference. The NDs in these cameras were a true first for imaging — there were no other electronically controlled variable NDs before the 2018 releases of these cameras.So, what does the LCND (and other electronically controlled glass filters) mean for the average filmmaker?A Better ND FilterImage via Panavision.Panavision is an industry leader in the cinema world. When they develop new products and technologies, the industry pays attention. With similar tech already available in Sony Cameras, and the overwhelmingly positive reception to the LCND, filter and camera manufacturers are likely to pick up on the trend.When the first variable NDs became available a decade or so ago, Chinese manufacturers quickly responded with affordable knock-off products. More reputable manufacturers released their own versions of these simple NDs after wide reception in the film, video, and photo markets.Andrew Reid of EOSHD has some cool ideas for what wider market electronic NDs might look like in the coming years in his blog post on the LCND. Low cost, screw-on filters with low-profile power or battery options would surely be a boon to independent camera operators.Image via Panavision.I hope to see more electronic NDs in the coming years. The ability to lock the Iris and control exposure remotely opens up all sorts of possibilities for the camera department.With existing tech in multiple consumer-driven markets to draw upon, removable electronic NDs might just be the very-near future of all NDs in video, now that Panavision has set the bar and established how these devices can work in cinema applications.No matter what happens, however, the LCND truly is one cool piece of gear.Cover image via Panavision.Looking for more articles on film and video equipment?

2012 Ducati Monster 795 launched in India

first_imgItalian motorcycle manufacturer Ducati launched the Monster 795 in India. The bike costs Rs. 6.99 lakh, say reports.Ducati has ditched single-sided swingarm and gone in for a conventional double-sided swingarm for the 795 to cut costs. Other changes include the lower, smaller, 696 trellis frame and its components, three-spoke alloys from the 696 and a steel handlebar sourced from India itself.The Monster 795 uses the 803cc, 90-degree V-twin, air-cooled engine found on the Monster 796, say reports. Power and torque figures are 87PS at 8250rpm and 78Nm at 6250rpm.Just like every Ducati, the 795’s ECU is programmed to cut fuel supply instantly whenever it detects high revs at low speeds. The Monster 795 comes with a six-speed gearbox. The 795 achieved the 0-100kmph feat in a mere 4.27 seconds. Top speed is over 200 kmph.The Monster has twin 320mm Brembo discs up front. It sports 43mm, upside-down Marzocchi forks at the front and the preload and rebound adjustable Sachs monoshock at the rear wheel.Seating position is lower on the 795, with saddle height lower than the 796 by 30mm, apart from the handlebar sitting 20mm lower.The Monster sports an all-digital dash incorporating a speedometer, tachometer, tripmeter, clock, maintenance warning, oil temperature, fuel tripmeter, lap time recorder, warning light for low oil pressure, low fuel light, shift light and immobiliser apart from the usual tell-tale lights.The system is also ready for connecting to the optional DDA (Ducati Data Analyser) system.last_img read more

Minister Highlights Importance of Music Tourism

first_img Minister of Tourism, Hon. Edmund Bartlett, says music tourism is a rapidly expanding market, which plays perfectly into Jamaica’s strength as the top entertainment destination in the region.Addressing the graduation ceremony for the DJ Capacity Building Training Programme at the Iberostar Hotels and Resorts, St. James, on June 21, Mr. Bartlett said to fully capitalize, “we are positioning” the tourism sector to work strategically with the music industry to create valuable products and experiences for visitors.“Our music continues to set Jamaica apart from rival destinations,” the Minister pointed out.“Each year more and more reggae music fans converge on the island to enjoy great music and the offerings of a remarkable destination. The resounding success of music festivals like Reggae Sumfest and Sting have helped to enhance our international profile significantly,” he added.Mr. Bartlett said that while the Ministry is committed to fostering the continued development of the entertainment industry and its full integration into the tourism product, he is fully cognizant that there is still more to be done to maximize the potential of “this important” sub-sector.“So, as we put in place the framework to further diversify our tourism product, we are well aware of the enormous benefits if we get this right,” Mr. Bartlett said.“We have to give visitors more things to do when they come to our island. We have to tap into their passion points, and music is a great way to start. Simply put, we are placing a special focus on developing entertainment tourism as part of our growth strategy,” he noted.Mr. Bartlett said that while the country’s goal of welcoming five million visitors annually remains on target, there is simply no room for complacency.He said that as good as the current offerings may be, stakeholders should always be looking to innovate and focus on growing earnings per visitor and retaining more of those earnings in Jamaica.“It goes without saying that entertainment is an area in which we are world beaters,” the Minister further added.“Therefore we are taking the necessary steps to capitalize on the tremendous potential Jamaica has in this area to significantly boost our arrivals and tourism earnings,” he said.The Minister commended the Head of the Ministry’s Sports and Entertainment Network, Entertainment Consultant and Promoter, Kamal Bankay, noting that “he is doing an excellent job leading this initiative.”“This is being done in collaboration with my colleague, Hon. Olivia Grange and her team from the Ministry of Culture, Gender, Entertainment and Sport,” Mr. Bartlett said.“We will also be leveraging February’s Reggae Month to appeal to visitors. In addition, the month marks the birthdays of Jamaica’s most recognizable musicians, the King of Reggae Bob Marley and the Crown Prince of Reggae, Dennis Brown, both great selling points,” the Minister said.
