first_img At the Valencia Country Club, organizers of the Champion Tour tournament are hoping for the best, with play scheduled today through Sunday, spokesman Matt Kovacs said. “We don’t think there will be a lot of rain, that’s what the forecast said,” Kovacs said. “It’ll be cold and wet, but we’re expecting to play.” The Weather Service issued a storm watch for the San Gabriel Mountains for this afternoon through Saturday night, warning that cold, snow and gusty winds could create deadly hazards for campers and hikers. Snow levels today could range between 2,500 feet and 3,500 feet, which could bring accumulating snow to 3,200-foot-elevation Escondido Summit on the Antelope Valley Freeway and to 4,100-foot Tejon Pass on Interstate 5. Snow levels are expected to drop to 2,000 feet between tonight and Sunday, falling in some spots to as low as 1,500 feet.

City spokeswoman Gail Ortiz said Santa Clarita has two large dump trucks fitted with snowplows standing ready. The National Weather Service said very cold air from Canada and Alaska will plunge southward, but the showery nature of the precipitation makes it likely that rainfall and snow amounts will be slight. “It’s going to be more showery. It mainly will be very cold weather,” weather specialist Bonnie Bartling said. SANTA CLARITA – City crews dusted off two snowplows Thursday. Caltrans workers in the region mobilized. And pro golfers in town for the AT&T Classic cast wary glances to the clouds, all responding to an unusual weekend forecast – snow flurries, hail and thunderstorms are expected across Southern California, perhaps as low as 1,500 feet, Santa Clarita’s elevation. “At this time, we have crews mobilized around the clock, day crews and night crews who are ready and waiting for the snow with snowplows and other heavy equipment,” said Jeanne Bonfilio, spokeswoman for the state Department of Transportation. Locally, the focus is on the Grapevine, and the Antelope Valley Freeway through Acton. Santa Clarita’s last substantial snow, in February 1989, prompted the closure of Interstate 5 through the Newhall Pass. last_img read more

first_img(Visited 31 times, 1 visits today)FacebookTwitterPinterestSave分享0 Some recent evolutionary papers appear to make physical laws not just constraints on natural selection, but guiding hands that build optimal designs.Hydrodynamics and the perfect transporter:  In cell membranes, aquaporins are hourglass-shaped channels that allow water molecules through but block other molecules.  Their “remarkable  selectivity,” coupled with “optimal permeability,” is admired by biophysicists – so much so that authors of a paper in PNAS about aquaporins [AQPs] remarked, “in a biomimetic perspective, these results provide guidelines to design artificial nanopores with optimal performances.”  How, then, did evolution stumble upon such design perfection?  “This suggests that the hourglass shape of aquaporins could be the result of a natural selection process toward optimal hydrodynamic transport.”   This statement could mean that natural selection found the optimal shape through blind search, but more implicitly that the laws of hydrodynamics lured natural selection toward “excellent water selectivity.”  Most of the paper focused on why the geometrical shape is so effective:The aim of this work was to determine the effect of geometry and BCs [boundary conditions] on hydrodynamic entrance effects in biconical nanochannels. Using FE [finite-element] calculations, we have shown that compared with a plain cylindrical pipe, a biconical channel of optimal angle can provide a spectacular increase in hydrodynamic permeability. A simplified model based on entrance effects and lubrication approximation rationalizes the observed behavior. Although speculative, this could indicate that the hourglass geometry of AQPs results from a shape optimization, to reduce end effects and maximize water permeability.They said very little about evolution.  What they did say amounts to an airy speculation that, somehow, physics drives evolutionary progress:Among transmembrane proteins, and ionic channels in particular, examples abound where the particular function––ion selectivity, for instance––is tied to a specific feature of the molecular architecture. However, it remains worth wondering, as we have done here, whether generic factors such as viscous dissipation could be the driving force behind the shapes fine-tuned by evolution.Fluid dynamics and the perfect lung:  More blatant in the assertion that physics drives evolution is a headline on PhysOrg, “How fluid dynamics and transport shaped the structure of our lungs in the course of evolution.”  The speculations of two French physicists goes beyond claiming that physics merely constrains evolution, though it overlaps with that notion.  It elevates physics to an essential player in the process of design optimization, a voice telling the evolutionary tinkerer, ‘you’re getting warmer’—In an evolutionary perspective, the size of primitive multi-cellular species was necessarily limited by nutrients’ diffusion speed. One hypothesis defended in this study is that larger primitive animals have thus been conditioned by a progressive Darwinian selection of tree-like ‘space-filling’ nutrient distribution systems. Then, their genetic material was ready to be shared to allow mammalian respiration. Successive inspirations and expirations cycles had to be optimised so that external air could reach the alveoli before expiration starts. This form of evolutionary tinkering, the authors believe, would have allowed the emergence of mammalian respiration—as opposed to fish-style breathing through gills.With physics in the driver’s seat, it’s no wonder that “the structure of the alveolar system is indeed optimal to allow efficient transport of oxygen from the air to the blood,” the article ends.  “This new insight into the lung’s evolutionary process stems from the physical principles underlying the architecture of living systems.”Evolution is a mystical form of polytheism for modern intellectuals.  Any questions?  You thought evolution was impersonal and unguided.  That would never work.  Cryptic spirits animate all of nature.They even have names.  The blind goddess Tinker Bell is helped by Engineer Bill, calling out “You’re getting warmer!” as the unholy spirit of Charlie, the Bearded Buddha, smiles down from above, “allowing” endless forms most beautiful to “emerge.”  Since these deities are invisible, one needs the shamans to interpret the game, continually offering “new insight” to the peasants, ever stringing them along to keep the funds flowing.  The Great Myth must remain a perennial work in progress, lest the shamans run out of business in their temples, the universities.  They shudder at the prospect of begging on street corners with signs, “Will tell stories for food.”last_img read more

first_imgShare Facebook Twitter Google + LinkedIn Pinterest Things are moving along. We are down to 130 or 140 acres of corn for ourselves and then 400 acres of custom work. We have been rolling pretty steady. We got three tenths over the weekend and that put us out until yesterday afternoon.We had pretty good bean yields. They were not as good as last year but we had a lot of beans go over 60 bushels. We were pretty satisfied with that.Corn has been all over the place. We had a lot of 200-bushel corn and a lot in the 180s. We had some corn around 100 bushels. There were a few fields that were not good but most of it has been pretty decent. The lowest field average we have seen was 82 bushels an acre, but that was a very wet farm and the last field we planted. We had several fields that averaged 220 dry.We have one other large acreage farm to go that has some water damage in it. We had some fields damaged with water where we thought we’d be lucky to get a 100 bushels an acre and they were anywhere from 125- to 150-bushel averages. I would not have thought they would make that.There is a lot of really bad corn in this area too. There are some fields around here where the whole field was shelled and they came out with one semi load. There have been a lot of fields around here under 100 bushels an acre. The only corn that is faring well was planted early and everything that did well around here for us was disked ripped last fall. We have one field that did well on gravel that is hilly and it is no-till, but it can handle the water.We have been doing some disk ripping and chiseling and it hasn’t been too bad, but a little rain won’t hurt anything.last_img read more

first_imgTags:#Analysis#news#NYT#web Top Reasons to Go With Managed WordPress Hosting marshall kirkpatrick Why Tech Companies Need Simpler Terms of Servic… A Web Developer’s New Best Friend is the AI Wai…center_img 8 Best WordPress Hosting Solutions on the Market The wildly popular nonprofit fundraising application Causes reportedly emailed users of its MySpace app on Tuesday to tell them that all Causes will be removed from MySpace on Friday morning, in three days. Causes was co-founded by Sean Parker, co-founder of Napster, the Comcast-acquired Plaxo and Founding President of Facebook. MySpace users of Causes were encouraged to post links on their MySpace profiles asking cause supporters to join the cause on Facebook instead. In abandoning MySpace, is Causes abandoning nonprofit groups organizing online with poorer users and people of color? Or are neither MySpace or Causes any big loss for social change organizations?The Politics of PoliticsAmy Sample Ward writes today on the Stanford Social Innovation Review blog that she’s concerned. “Causes leaving MySpace,” she writes, “means that no users there will be able to continue promoting the causes, organizations or sectors that they care about via a process that’s already been established, adopted, and networked.“[The] Causes’ About statement says, ‘The goal of all this is what we call equal opportunity activism. We’re trying to level the playing field by empowering individuals to change the world.’ The removal of Causes from MySpace where there are active communities of supporters means ‘equal opportunity activism’ is defined by only certain communities – we know that social networking platforms have very different demographic user groups.”So Sample Ward argues that Causes is being hypocritical by allowing equal access to tools for social change to be defined only by the more economically powerful demographic groups on Facebook. Causes told users it was pulling out of MySpace because of a lack of activity, but the MySpace App Gallery says there are almost 190,000 active Causes users right now, making it the third most popular app in the politics and causes category.Housing rights nonprofit exec Justin Massa concurs with Sample Ward and takes the critique a step further: “Causes’ justification sounds an awful lot like what financial institutions and the real estate industry used to say about poor and minority neighborhoods. I’m planning a longer post on this subject early next week, but in the meantime wanted to label this for what it is: social network redlining. ” [Our link added for clarity.]On MySpaceNot everyone thinks that MySpace provides a meaningful opportunity to effect social change, though. In an interview four years ago on the topic of nonprofit promotion on MySpace, Pete Cashmore of social network tracking blog Mashable articulated what’s now a widely-held belief. He said he believed MySpace was really just filled with young, drunken, hyper-sexualized, attention seekers. “You’ve been there…it seems crazy for organizations to invest time and resources there,” he said, “but it’s popular!” Not everyone sees it that way. The Humane Society, for example, posts daily to MySpace about animal welfare issues for its 65k+ friends. Causes co-founder Sean Parker poses sitting with crossed legs in his photo on the company profile page; his mission statement begins with the words “According to the historical Buddha…” It’s hard to imagine a beneficent religious figure that would ditch MySpace for Facebook, isn’t it? Perhaps “the historical Buddha” would choose to pull up stakes from the 11th most popular website in the world if the people were too shallow and go to the hip social network where the money-raising action is.The Loss of CausesPerhaps even more cynical are some of the attitudes around Causes itself. This Spring the Washington Post reported that despite big expectations from many nonprofit organizations, posting a Causes app to a Facebook profile and waiting for the money to roll in is a sure path to disappointment.“Only a tiny fraction of the 179,000 nonprofits that have turned to Causes as an inexpensive and green way to seek donations have brought in even $1,000, according to data available on the Causes developers’ site. The application allows Facebook users to list themselves as supporters of a cause on their profile pages. But fewer than 1 percent of those who have joined a cause have actually donated money through that application.”Widely respected nonprofit technology consultant Beth Kanter says that Causes is like a one-night stand. “Where’s the opportunity to cultivate and get to know those joiners and move them up the ladder to donation?” she asks, “Where’s the relationship building?”So by pulling out of MySpace, is Causes abandoning some of the people who need it most? Or is MySpace a bad place to do political organizing anyway? Or, is Causes just not a great way to organize and fundraise? There’s a lot of negative feelings around this news, but maybe that’s what happens when the struggling nonprofit technology sector puts too much stock in the dalliances of a big-named Silicon Valley baron like Sean Parker.Kanter brings a twinkle of optimism to the conversation: “This sounds like a great opportunity for other fundraising applications,” she says.

Ohio State wideout Johnnie Dixon reels in a touchdown reception in the fourth quarter of the Buckeyes’ 39-38 win on Oct. 28. Credit: Jack Westerheide | Photo EditorDown 15 points to No. 2 Penn State (7-1, 4-1) in the fourth quarter, No. 6 Ohio State (7-1, 5-0) looked finished. Quarterback J.T. Barrett fumbled the ball, turning it over with 13:13 remaining as the Columbus crowd’s screams turned to dulcet tones. But the Buckeyes never panicked. Cornerback Denzel Ward blocked a punt and two plays later, Barrett hit wideout Johnnie Dixon for a 38-yard touchdown. Ohio State held the Nittany Lions to a field goal and responded as Barrett once again found Dixon, this time for a 10-yard touchdown.And after Penn State went three-and-out, Barrett put the finishing touches on what head coach Urban Meyer called the best comeback of his career. He dropped back and delivered a strike to tight end Marcus Baugh in the end zone to give the Buckeyes a one-point lead, their first of the game, with 1:48 remaining in the final quarter. The advantage would hold as Ohio State survived, winning 39-38 Saturday at Ohio Stadium and remaining in contention for the College Football Playoff.“Honestly, we’ve been in those situations quite a bit, whether it be spring ball or fall camp,” Barrett said. “What was going through my head was Coach Meyer saying go win the game. He says that all the time, go win the game.”Barrett followed up five weeks of increasingly impressive play with the best game of his career which potentially thrust him into Heisman Trophy contention, completing 33-of-39 passes for 328 yards and four touchdowns. He also raced for 95 carries on 17 yards, succeeding taking multiple zone reads for 10-plus yards. “I’ve never had a kid play perfect, but damn he was close tonight — 33 of 39,” Meyer said. “I can count four drops off the top of my head and two penalties that kept him from big completions.”Though the Buckeyes outgained Penn State through the air (328-192) and on the ground (204-91), they trailed for the first 58 minutes of the game due to many special teams blunders which have plagued them throughout the season.It took just 15 seconds for Ohio State to seemingly realize its nightmare scenario as Penn State running back Saquon Barkley caught a well-placed kickoff and raced 97 yards, giving the Nittany Lions the early lead, which they nearly never relinquished. The Nittany Lions capitalized on a multitude of Ohio State mistakes as the home team seemingly could not get out of its own way at times. The Buckeyes committed 10 penalties for 79 yards, including four false starts. Safety Damon Webb intercepted a pass in the end zone, but cornerback Damon Arnette was flagged for pass interference which set the Nittany Lions up at the 6-yard line and quarterback Trace McSorley ran in for a touchdown on the next play.Ohio State’s defensive front managed to bottle up the Nittany Lion rushing attack for much of the game, but Barkley broke free for a 36-yard touchdown early in the second quarter and finished with just 21 rushes for 44 yards and four catches for 23 yards.“My biggest concern was not just the fact he’s a great running back, but he had 21 carries for 44 yards, if I’m reading that right. Is that right?” Meyer said, incredulous.McSorley finished the game 17-of-29 for 192 yards and two touchdowns. He made his most prominent impact in the rushing game as he carried the ball 13 times for 49 yards. He had a crucial 10-yard rush on 3rd and 10 early in the third quarter, which extended a drive, leading to Penn State scoring its fifth touchdown and taking a 35-20 lead.In the third quarter, Ward nearly pulled off an interception, but due to both he and wideout DeAndre Thompkins having possession, the Nittany Lions scored a touchdown.Freshman running back J.K. Dobbins exploded for four carries for 50 yards in the first quarter, but was conspicuously absent from the game in the second quarter. He returned to the game in the third quarter and finished with 13 carries for 88 yards. While Dobbins was out, the Buckeyes relied heavily on redshirt sophomore running back Mike Weber, who ran the ball seven times for 21 yards and scored a 2-yard touchdown up the gut in the second quarter.Wideout K.J. Hill set a career high in receptions as he led Ohio State with 12 catches for 102 yards, often acting as Barrett’s short-range target. Ohio State will be back in action Saturday afternoon in Iowa City, Iowa, taking on the Hawkeyes. read more
