Study shows how to keep a Mars tumbleweed rover moving on rocky terrain

Wednesday, May 23, 2012

New research from North Carolina State University shows that a wind-driven "tumbleweed" Mars rover would be capable of moving across rocky Martian terrain ? findings that could also help the National Aeronautics and Space Administration (NASA) design the best possible vehicle.

"There is quite a bit of interest within NASA to pursue the tumbleweed rover design, but one of the questions regarding the concept is how it might perform on the rocky surface of Mars," says Dr. Andre Mazzoleni, an associate professor of mechanical and aerospace engineering (MAE) at NC State and co-author of a paper describing the research. "We set out to address that question."

Mazzoleni and Dr. Alexander Hartl, an adjunct professor of MAE at NC State, developed a computer model to determine how varying the diameter and mass of a tumbleweed rover would affect its speed and ability to avoid getting stuck in Martian rock fields. Rock fields are common on the surface of Mars, which averages one rock per square meter.

"We found that, in general, the larger the diameter, and the lower the overall weight, the better the rover performs," Mazzoleni says. In addition, the study found that a tumbleweed rover would need to have a diameter of at least six meters in order to achieve an acceptable level of performance ? meaning the rover could move through rock fields without getting stuck.

Using the model, the researchers also found that tumbleweed rovers are more likely to bounce than roll across the surface, due to the spacing of the rocks and the size of the rovers.

"Computer simulations are crucial for designing Mars rovers because the only place where you find Martian conditions is on Mars," says Mazzoleni. "Earth-based testing alone cannot establish whether a particular design will work on Mars." Mars has approximately three-eighths of Earth's gravity. And the atmospheric density on the surface of Mars is only duplicated around 100,000 feet above the Earth's surface.

Tumbleweed rovers are attractive because they can cover much larger distances, and handle rougher terrain, than the rovers that have already been sent to Mars ? such as Spirit and Opportunity. "This model is a tool NASA can use to assess the viability of different designs before devoting the time and expense necessary to build prototypes," Mazzoleni says.

While tumbleweed rovers would lack the precise controls of the wheeled rovers, they would also not rely on a power supply for mobility ? they would be literally blown across the Martian landscape by the wind.

###

The paper, "Terrain Modeling and Simulation of a Tumbleweed Rover Traversing Martian Rock Fields," is published in the March/April issue of the Journal of Spacecraft and Rockets.

Docs slower to drop 'black box' drugs, adopt new therapies, when access to drug reps is restricted

Docs slower to drop 'black box' drugs, adopt new therapies, when access to drug reps is restricted [ Back to EurekAlert! ] Public release date: 23-May-2012

After years of reducing their contact with pharmaceutical sales representatives, physicians now risk an unintended consequence: Doctors who rarely meet with pharmaceutical sales representatives or who do not meet with them are much slower to drop medicines with the Food and Drug Administration's "black box" warnings and to adopt first-in-class therapies.

According to a study published May 21 in The Journal of Clinical Hypertension, doctors whose access to pharmaceutical sales representatives is limited can take more than four times longer to change prescriptions based on new information than their peers who have more frequent contact. This longer response time holds true whether the physicians are responding to "positive news" related to an innovative therapy or "negative news" related to a newly discovered medicine risk.

George Chressanthis, professor of healthcare management and marketing and acting director for the Center for Healthcare Research and Management at Temple University's Fox School of Business, led the study in collaboration with ZS Associates, a global sales and marketing consulting firm with a very deep presence in the health care industry.

"This study analyzed for the first time and on a large scale what happens to physicians' prescription decisions when you decrease the access that pharmaceutical sales reps have to doctors," Chressanthis said. "We saw that increasing access restrictions affect physician decision-making in ways not anticipated by those at health care systems or large group practices who created these policies."

Chressanthis, his research team and ZS consultants began to measure the behavior of primary care physicians and specialists in 2008 when Chressanthis was at AstraZeneca Pharmaceuticals LP. They drew from ZS' annual AccessMonitor report, which since 2006 has tracked how frequently 300,000 physicians and other prescribers meet with pharmaceutical sales reps. According to AccessMonitor, the number of doctors willing to see reps has declined about 20 percent since 2008. In 2010, about 11 percent of American physicians had "severe" or "no-see" restrictions on rep access, while 34 percent had "some" restrictions.

The study measured prescription activity and behavior by primary care physicians and specialists from 2006-2008 as it related to the following three major product events:

  1. The October 2006 launch of a first-in-class drug to treat Type 2 diabetes (sitagliptin) (physician sample size: 65,088);
  2. the August 2007 issue of a black box warning (i.e., the FDA's most serious medication warning) for a drug (rosiglitazone) used to treat Type 2 diabetes (physician sample size: 58,647); and,
  3. the January 2008 release of a negative outcome associated with a therapy that combined a cholesterol-lowering drug (simvastatin) and another medicine (ezetimbe) to treat dyslipidemia (physician sample size: 72,114).

In the case of sitagliptin, physicians with a "very low" level of sales rep access took up to 4.6 times longer to introduce the new drug to patients than physicians who employed a "medium" level of access. For the black box warning, physicians with "very low" access were up to four times slower to reduce their use of this treatment than physicians with "low" access. In the clinical trial involving the negative outcomes of a lipid therapy prescription, physicians who limited sales rep access showed "significantly less" response in changing their patients' prescriptions than did physicians in less restrictive offices.

ZS managing principal Pratap Khedkar, co-author of the study, said the research demonstrated that most physicians should seek to balance their information sources.

"Though health care professionals work hard to minimize distractions and maximize the time they spend with patients, it's clear that sales rep access restrictions imposed by well-meaning physicians and group practice leaders can result in serious information gaps," Khedkar said. "Even though pharmaceutical sales representatives are not the only source of information, they do help physicians stay current on therapy developments. These findings should be carefully considered by those who set policy whether it's at the physician group practice level or on the national stage."

The study also showed primary care physicians rely more heavily on sales reps for drug information than do specialists. "When primary care physicians reduce or eliminate contact with these reps, it impairs their ability to stay current and affects their prescription behavior," Khedkar said. "Because specialists concentrate in a narrow field, they can stay current by other means, including conferences, online forums, podcasts and academic journals. Thus, the updates they receive from reps have less impact on their prescribing abilities."

Chressanthis provides these final notes about the importance of this study. "Our study affirms simple intuition that when physicians have to make decisions involving complex issues with less than complete information available to them, and where the consequence of a wrong decision is significant as seen often in healthcare, unintended consequences are likely to appear," he said. "Policies that promote physician ignorance of new medical information resulting from access limits runs counter to protecting patient health."

###

Beside Chressanthis and Khedkar, the report authors also include Nitin Jain, ZS principal; Prashant Poddar, ZS consultant; and Michael Seiders, formerly Director of Strategic Public Policy Planning at AstraZeneca. Lead author Chressanthis was employed at AstraZeneca from 2000-2009. He still retains stock grants in AstraZeneca. The research was funded by AstraZeneca Pharmaceuticals LP.

Julius Genachowski voices support for capped, tiered broadband

julius-genachowski-capped-broadbandFCC honcho Julius Genachowski has come out in favor of usage-based pricing for your broadband. At this year's Cable Show, he said that he supported the sort of usage caps that Comcast adopted last week and hoped that such plans would reduce costs for those who use less internet. Comcast's new pricing structure offers a 300GB monthly cap, after which point it'll charge users $10 for every extra 50GB used. We're not sure how this'll play out, but we suspect anyone with a Netflix or Hulu addiction might feel less than pleased this morning.

10 Sci-Fi Faster-Than-Light Systems

Found in: Star Trek

Warp drive is surely the most famous way to get your butt to a distant star. But, as with anything related to Star Trek, there's not a simple explanation. The basic story is that if you combine matter and antimatter fused with some dilithium, you can create a subspace bubble that exists outside the normal fabric of space?time. With warp plasma spewing out of a ship's nacelles you can now propel yourself faster than light to varying degrees (the famous "warp factor" you'll often hear Starfleet captains shouting about).

Maintaining a warp drive ain't easy, which is why every iteration of Star Trek had an (awesome) chief engineer and a set with a big blue glowy thing. For that reason alone it is at the top of the list.

Plausibility Factor: We're gonna give this one an 8 and direct you to the work of Miguel Alcubierre. In 1994 he presented a paper on the "Alcubierre Drive" that presents concepts very similar to a warp bubble.

Defining Moment (The Note)

By MICHAEL FALCONE ( @michaelpfalcone ) and AMY WALTER ( @amyewalter )

NOTABLES: ?

DEFINE OR BE DEFINED: With Democrats trashing Mitt Romney's business record at Bain Capital, the presumptive Republican nominee is attempting to wage the presidential campaign on his terms. He released his first general election television ad today - a seemingly positive vision of his top priorities if elected. But as ABC News Political Director Amy Walter points out, the ad amounts to a subtle - but razor-sharp - contrast to President Obama.

IN THE HOUSE: ?A "This Week" exclusive on Sunday. ABC's George Stephanopoulos sits down with House Speaker John Boehner and Democratic Leader Nancy Pelosi about simmering tensions on Capitol Hill on the budget, taxes and other key issues.

NOTE IT! In our virtual political roundtable, ABC's Amy Walter on why Republicans are all of a sudden walking with a spring in their step and Rick Klein on the perils of the super PAC era.

THE NOTE:

During a week when Democrats kept Mitt Romney on defense with their attacks on his work at a private equity firm - attacks that Romney said he considers "character assassination" - the presumptive Republican nominee attempted to regain his footing by unveiling his first television ad of the general election.

The ad, titled "Day One" envisions the first day of a Romney presidency, and according to the 30-second spot, it will be a busy one. (WATCH:? http://bit.ly/Johw5H)

"President Romney immediately approves the Keystone pipeline,?creating thousands of jobs that Obama blocked," the ad's announcer says. ?"President Romney introduces tax cuts and reforms that reward job creators, not punish them. President Romney issues order to begin replacing Obamacare with commonsense health care reform."

The ad will run in several battleground states, including Virginia, Ohio, Iowa and North Carolina.

But the Romney campaign's description of this as a "positive" ad should get a "pants on fire" rating. It is simply a criticism of the Obama administration but with pretty images and softer tones instead of ominous music and scary voices.

It follows on the heels of a one-two punch earlier this week from the Obama campaign and an allied super PAC, Priorities USA Action, which attacked Romney's record at Bain Capital. Both released television ads highlighting job losses at a Kansas City steel company taken over by Bain.

"The issue that will never go away - Mitt Romney's career as a corporate raider and his creation of Romney Economics," Democratic National Committee spokesman Brad Woodhouse noted this morning, introducing a new web video that keeps Bain front and center. (WATCH: http://youtu.be/No0jNi5Vv3U)

It's more evidence that the Obama campaign and Democrats are doing everything they can to try to define Romney faster than he can define himself.

"The purpose of the president's ads are not to describe success and failure, but somehow to suggest that I'm not a good person or not a good guy," Romney said at a campaign stop in Florida yesterday, "and I think the American people will know better than that."

Nevertheless, the former Massachusetts governor's challenge is clear.

"He must demonstrate how and why the man who ran Bain Capital, the man who relished 'creative destruction,' the man who gave Obamacare a test run in Massachusetts and who knows of?NASCAR?only through his acquaintances with various team owners provides the better choice for a more hopeful, more prosperous America," Republican strategist Ford O'Connell notes in a US News commentary. "He doesn't have to be perfect. He doesn't have to be likeable. But he does have to be someone we think we know and understand." http://bit.ly/KjgIic

NOTE IT!

ABC's RICK KLEIN: It's not that pretty, but we may have stumbled onto something important about the super PAC era in the events of the last 24 hours. The fact that the public learned the identity of the person considering Jeremiah Wright ads - a person who founded a major online brokerage and whose family controls a baseball team - contributed mightily to the fact that the ad isn't running, and may never run. The major players in super PACs haven't been shadowy figures, they've been out in the sunlight, or at least close enough to it that they have the potential to wilt in its shine.

ABC's AMY WALTER: For the first time since this cycle, Republican strategists and politicos are starting to really believe that Romney can win this thing. A combination of strong polling numbers nationally and in traditionally blue states like Wisconsin, combined with good fundraising numbers (and a lack of Democratic firepower on the super PAC side) has given the GOP a spring in their step that had been missing for much of the last few months.

VEEP BEAT: Our daily look at all the action on the veepstakes front, brought to you by ABC's Arlette Saenz ( @ArletteSaenz ):

RUBIO WARNS OF 'DAILY' DEBT CEILING CRISIS: ?While Congress won't have to vote on raising the debt ceiling until, Sen. Marco Rubio, R-Fla., still warned that the country is facing a debt ceiling crisis "daily" and criticized Secretary Treasury Timothy Geithner's suggestion that a debt ceiling crisis does not exist.??We are having a debt ceiling crisis on a daily basis, and here's why," Rubio said in a FOX News interview Thursday. "Because this government every year is spending $1.5 trillion more than it takes in."? http://abcn.ws/LYacRv

RUBIO ON VEEPSTAKES: ?"I'm curious to see who it's going to be." ("Your World with Neil Cavuto," 5.16.12)

MEET THE RUBIOS: ?In her first ever extended interview, Jeanette Rubio joined her husband Marco Rubio to discuss their family life with Politico and expressed that she is prepared for whatever scrutiny the couple may undergo as his national profile begins to rise.??"I'm prepared for the idea that no matter what he does - especially when there's talk of him being the VP candidate - that [there] are things that are going to come out," Jeannette Rubio told Politico.. "And through the Senate campaign, we already went through a lot. ? That really prepared us, or at least me." The interview shares the story of how they met, endured distance relationship in the age of no-Skype (Marco Rubio wrote long letters), and how they maintain a strong family.?? http://politi.co/JWu4Wi

CONDI: 'I DON'T REALLY LOVE POLITICS'? ?ABC News' Emily Friedman highlights this NBC Chicago report that Condoleezza Rice again said she will not be Mitt Romney's running mate, saying she doesn't really have that loving feeling for politics. "Not going to happen," she told the audience. "I love policy, I don't really love politics," Rice said at a speech in Chicago Thursday.??"One can do a lot with policy not in Washington." http://bit.ly/JjLoqk

VIDEO OF THE DAY: GEORGE ON JOHN. George Stephanopoulos tackles the question "can John Edwards come back?" in the latest installment of George's "Bottom Line" part of ABC's News/Yahoo!'s Power Players Series.?"But even an acquittal is only the beginning" Stephanopoulos says. "To understand why, look no farther than a? recent?New York Times/CBS News poll?showing that Edwards' approval rating is an unfathomably low 3% - and that drops to 2% among women. I've never seen an approval rating so low in any kind of poll."? http://abcn.ws/L3pQJe

THE BUZZ

with ABC's Elizabeth Hartfield ( @LizHartfield)

ROMNEY REJECTS ADS AIMING TO TIE OBAMA TO REV. JEREMIAH WRIGHT . Yesterday Mitt Romney rejected reports of a plan to air attack ads against President Obama by rehashing ties to his former pastor, the controversial Rev. Jeremiah Wright, reports ABC's Emily Friedman. The plan, which was first reported by the New York Times on Thursday, had a $10 million price tag, and was? developed by "a group of high-profile Republican strategists" and Joe Ricketts, the founder of TD Ameritrade.? http://abcn.ws/ Jy7a7y

-ABC's Jake Tapper dissected the immediate distance Romney put between his campaign and the proposal:? http://abcn.ws/ JLaCLc

-Democrats were quick to point out comments Romney had made on Obama's relationship with Wright during an interview with Sean Hannity, notes ABC's Matt Negrin.? Romney?said he believed Obama didn't understand "that Judeo Christian philosophy is an integral part of our foundation."?"I'm not sure which is worse: him listening to?Rev. Wright or him saying we must be a less-Christian nation," Romney said. Romney addressed his comments to Hannity on Thursday - "I'm not familiar with precisely what I said, but I stand by what I said, whatever it was," Romney said.? http://abcn.ws/J3Uz9y

-One of the strategists who reportedly oversaw the proposal was GOP ad man Fred Davis- whose resume boasts a long list of buzzy political ads, including Christine O'Donnell's infamous "I'm Not A Witch" ad from 2010. ABC's Amy Bingham takes a look at some of the highlights in his reel.? http://abcn.ws/Klbiou

-And ABC's Shushannah Walshe takes a look at the risk vs. reward of going negative in political ads.? http://abcn.ws/KX6sAe

SENATOR COBURN: RETURN THE TAXPAYERS MONEY FOR THE CONVENTIONS . Senator Tom Coburn has his eye on a bigger target than the $800,000 GSA conference in Vegas- the Republican and Democratic conventions. ABC's Jon Karl reports that as of May 3, the Republican and Democratic parties have each received checks from the U.S. Treasury for a total of $36.5 million to be spent on their conventions in Charlotte and the Tampa this summer.? Now Coburn has written a letter to RNC Chairman Reince Priebus and DNC Chairwoman Debbie Wasserman-Schultz asking them to give the money back.? "Can we agree once and for all the party is over when it comes to travel and meetings paid for by the taxpayers?" Coburn wrote in a letter on Thursday.? http://abcn.ws/ JjiKFJ

MATT DOWD: WHAT PALIN CAN TEACH OBAMA ABOUT SEIZING THE MOMENT. Life is really about the moments and whether we're ready to take advantage of them- says ABC's Matt Dowd. "In the campaign during the last few weeks, I see two of those moment opportunities having surfaced" Dowd says. "President Obama and his campaign bypassed one key moment, while Sarah Palin took advantage of the other. It kind of shows the difference between a politician and campaign that makes decisions tethered to a plan and from logic, and another who makes decisions based on their gut and from their heart."? http://abcn.ws/KwPwlZ

FAREWELL AMERICANS ELECT. The third party group that sought to nominate a third party presidential candidate through an online nomination process officially its nomination process on Thursday, reports ABC's Amy Bingham. No candidate met the minimum requirements for nomination set forth by the group of 10,000 "clicks"- 1,000 from 10 states.? http://abcn.ws/JW9Onu

UNINTENDED CONSEQUENCES: RICKETT'S ANTI-OBAMA PLOT RISKS CUBS STADIUM GROWTH. Bloomberg's John McCormick and Julie Bykowicz report: "The admission by a Ricketts' spokesman yesterday that one proposed advertising campaign focused on the president's relationship with a Chicago preacher known for racially charged sermons removed the element of surprise, increased scrutiny of his political activity and put at a negotiating disadvantage one of the Ricketts family's prized possessions - the Chicago Cubs?The Ricketts' standing in?Chicago, Obama's hometown and a city dominated by Democrats, is diminished at a time they are looking for political and financial support to make renovations to 98-year-old Wrigley Field baseball stadium and the neighborhood around it."? http://bloom.bg/JkMvpD

ROMNEY PRAISES CLINTON, OBAMA PRAISES REAGAN. The New York Times' Peter Baker reports: "To listen to the candidates on the campaign trail these days is a form of political whiplash. Mr. Romney lavishes praise on the very Democratic Mr. Clinton for breaking with his party's traditional big-government orthodoxy, while Mr. Obama harks back to the very Republican Mr. Reagan for agreement that millionaires should not pay lower tax rates than the middle class."? http://nyti.ms/M0jYmq

OBAMA SADDENED BY DONNA SUMMER'S DEATH. Yahoo!'s Olivier Knox reports: "President Barack Obama said Thursday that he and first lady Michelle Obama were "saddened" to hear of the death ?of?"Disco Queen" Donna Summer.

Our thoughts and prayers go out to Donna's family and her dedicated fans,' the president said in a written statement." http://abcn.ws/JRjka7
