Simulation study for ground-based Ku-band microwaveobservations of ozone and hydroxyl in the polar middle atmosphere

first_imgThe Ku-band microwave frequencies (10.70–14.25 GHz) overlap emissions from ozone (O3) at 11.072 GHz and hydroxyl radical (OH) at 13.441 GHz. These important chemical species in the polar middle atmosphere respond strongly to high-latitude geomagnetic activity associated with space weather. Atmospheric model calculations predict that energetic electron precipitation (EEP) driven by magnetospheric substorms produces large changes in polar mesospheric O3 and OH. The EEP typically peaks at geomagnetic latitudes of ∼65∘ and evolves rapidly with time longitudinally and over the geomagnetic latitude range 60–80∘. Previous atmospheric modelling studies have shown that during substorms OH abundance can increase by more than an order of magnitude at 64–84 km and mesospheric O3 losses can exceed 50 %. In this work, an atmospheric simulation and retrieval study has been performed to determine the requirements for passive microwave radiometers capable of measuring diurnal variations in O3 and OH profiles from high-latitude Northern Hemisphere and Antarctic locations to verify model predictions. We show that, for a 11.072 GHz radiometer making 6 h spectral measurements with 10 kHz frequency resolution and root-mean-square baseline noise of 1 mK, O3 could be profiled over 8×10−4–0.22 hPa (∼98–58 km) with 10–17 km height resolution and ∼1 ppmv uncertainty. For the equivalent 13.441 GHz measurements with vertical sensor polarisation, OH could be profiled over 3×10−3–0.29 hPa (∼90–56 km) with 10–17 km height resolution and ∼3 ppbv uncertainty. The proposed observations would be highly applicable to studies of EEP, atmospheric dynamics, planetary-scale circulation, chemical transport, and the representation of these processes in polar and global climate models. Such observations would provide a relatively low-cost alternative to increasingly sparse satellite measurements of the polar middle atmosphere, extending long-term data records and also providing “ground truth” calibration data.last_img read more

Horse Sport Enews The Canadian Show Jumping Team finished fifth in the $150,000 CSIO4* Nations’ Cup, presented by Premier Equestrian, held Friday, March 5, at the Winter Equestrian Festival in Wellington, FL.Erynn Ballard, Mario Deslauriers, Tiffany Foster, and Amy Millar represented Canada in the only Fédération Equestre Internationale (FEI) sanctioned senior team event held during this year’s Florida winter circuit. A total of eight teams competed for victory over tracks set by American course designers Steve Stephens and Nick Granat including Brazil, Canada, Colombia, Great Britain, Ireland, Israel, Mexico, and the United States.In a change of schedule from prior years, the first round got underway at 4:30 p.m. ET followed by the second round at 7:30 p.m. At the mid-way point, Ireland led with a clear scoresheet after all four of its riders produced clear rounds. The United States followed in second with a single time fault and Israel was in third with four faults. Brazil was next in the provisional standings with eight faults while Canada and Great Britain were tied in fifth position with 12 faults. All eight teams moved forward to the second round.Foster, 36, of North Vancouver, BC, acted as Canada’s lead-off rider with Northern Light, a 10-year-old Swedish Warmblood mare (Plot Blue x Contender) owned by Foster in partnership with Artisan Farms LLC. In the mare’s Nations’ Cup debut, the pair posted scores of eight faults in both rounds.Ballard, 40, of Tottenham, ON, was riding Gakhir, a 10-year-old Dutch Warmblood gelding (Spartacus x Indorado) owned by Ilan Ferder and Esperanza Imports LLC. Incurring eight faults in the opening round, the newly-formed partnership kept it to four faults the second time out.Millar, 44, of Perth, ON, was the star of the night with Truman, a 12-year-old Selle Français gelding (Mylord Carthago x Kolibri) owned by Millar Brooke Farm Ltd. and Overlund. Looking fresh and confident, the pair left all the rails in place both times they toured the track to deliver a double clear performance.As the most experienced member of the Canadian team, Deslauriers, 56, of New York, NY, acted as the anchor. An unlucky rub at the double combination in the first round led to four faults, while it was a rail at the triple combination that fell during round two for another four-fault performance. The Wellington event marked the first time Deslauriers was riding Uris de la Roque, a 13-year-old Selle Français gelding (Capital x Quick Star) owned by Aram Ampagoumian LLC in partnership with Deslauriers, in Nations’ Cup competition.“All the Canadian horses jumped very well in the Nations’ Cup,” said Mark Laskin, Chair of the High Performance Jumping Committee. “We had three new horses that hadn’t competed for Canada previously and they gained critical experience towards their future careers. Special recognition should be given to Amy Millar who laid down two picture perfect rounds and led the way for us with a double clear performance.”On the event’s 20th anniversary, it was the United States that claimed victory in the $150,000 CSIO4* Nations’ Cup with the one fault incurred in the opening round. Ireland placed second on four faults, Brazil finished third on 14, and Israel fourth on 16 faults. Canada was fifth with a two-round total of 20 faults while Great Britain finished sixth with 24 faults. Colombia and Mexico took the final two placings in the standings with scores of 29 and 33 faults respectively.

Kinky Boots review

first_imgKinky BootsFor all the complaints about the semi-ghettoisation of British cinema, it often appears closer to its American mainstream counterparts, using the same emotional tricks and feel-good conventions. Julian Jarrold’s Kinky Boots is no exception, composed of generic set pieces and vaguely emotive pathos; a prime example of both the genre’s strengths and its failings.The premise of the film is vaguely quirky, about a failing shoe factory, transvestites, and a conflict between Northern sensibilities and metrosexual mores. Within this, there are the sketchy vestiges of social commentary, and the film even manages to inject a certain amount of tart humour. With a classical narrative ploy of the returning son, and a voyage of re-discovery both for hero and for community, the feel-good atmosphere that pervades the film is nothing we haven’t seen before. It’s practically made for Channel 4, in spirit if not in practice, and will most likely be more than moderately commercially and critically successful.Yet viewed objectively it looks calculated, a compilation of moribund motifs and touchstones from other movies. Its muted panoramas of a failing industrial Northern community is inferior to works such as 1996’s Brassed Off. Even The Full Monty, to which it must be inevitably compared, bettered its attempts at drawing analogies between masculine insecurity and declines in communities. Ironically, Kinky Boots’s greatest weakness is that when it comes to its central issue, its rather too successful for its own dramatic good. By showing us the complications of being true to oneself in a world which has abandoned its certainties in favour of style and transience, it only shows up the complete lack of core to the movie itself, disguised behind a thin layer of cliché.In its attempts to appear altogether liberal and sensitive in its sensibilities, Kinky Boots inevitably limits both its comic potential and the lucidity of its message. The film proclaims that the problem lies not with the individual, but with the interpretation of the social group, and then glorifies the mildly rebellious aims and effects of gender blurring. One character in especial, Lola/Simon, forms the focus for this discussion of gender, but Jarrold doesn’t have the conviction to address the reasons, save for a faintly charming Billy Elliot style flashback sequence. The film as it is cannot tackle these serious questions while still maintaining a primarily comedic tone; as a result, it fails to do either properly and is torn apart by its own paradoxes.The film also soft-peddles, surprisingly, on issues of sexuality. Lola/Simon might be torn, the film suggests discreetly, between a tensely flirtatious friendship with his boss Joel and a faintly flickering thing for his boss’s Northern Lass love interest, but it all ends in typical romance, with Lola left bullish but alone on stage, replete with heels and no hang-ups. Like another character, Chiwetel, when faced with real neurosis the film prefers to stave it off through glitzy set pieces and hollow music numbers.Kinky Boots proudly acknowledges its “based on a true story” origins. This doesn‘t, however, preclude its use of several horribly “quirky” stock-types, such as the eccentric but curiously unshock-able old  landlady. The acting is solid all-round, from both principals and supporting cast, and the cinematography is competent but uninspiring. In the end, though, there is nothing to set this film apart from the chain of look-alikes that have preceeded it in the British film industry.Our nation as it portrayed in its movies seems to be no more than a stockpile of stereotypes and platitudes. From the floppy-haired foppishness of Hugh Grant, to the feisty Northern strippers of The Full Monty, and now with more clichéd Brits to add to the list in Kinky Boots, we cannot seem to muster the courage to make a mainstream film that breaks free from these tired comic motifs. What we need in Britain is not a stiff upper lip, but a film industry with real imagination.ARCHIVE: 1st week MT 2005last_img read more

Pro-Test to march despite death threats

first_imgPro-Test, an organisation that favours animal testing, claims that it has been subjected to death threats and violence in the run up to its march through Oxford tomorrow.  The group has given a statement to the Thames Valley Police who are currently attempting to trace the sender of two emails of violent content. In a separate incident two members of the committee were approached and threatened by an individual on Cornmarket Street while promoting Pro-Test literature on a stall.  Tom Holder, a spokesperson for Pro-Test, explained, “The police are taking both incidents seriously. We were initially sent an email, which mistakenly suggested that the UK was still involved in cosmetic testing. We sent a polite reply to this email correcting this mistake. The individual then replied, simply saying, ‘Fuck off’. Then a second reply was sent in which a more serious threat was issued. However given how easy it is to send anonymous emails we expect this incident to turn out to be a childish prank.”The other incident on Cornmarket Street occurred when Kevin Elliot, a disabled member of Pro-Test, and a colleague were distributing leaflets from a stall in the afternoon.  Elliot said, “We were handing out leaflets and a guy came over to us who seemed to be interested, and asked what we were doing. He suddenly started swearing at us, and threw some of our leaflets at us and gave one of us a shove. He turned to me and said, ‘Good job you’re using crutches’ and kicked over a table, which went flying. “We didn’t do anything either to provoke or to retaliate them. As he was walking away, I shouted ‘It’s going to take a lot more than that to stop us.’”He added, “I was sort of expecting it, I think largely the animal rights lobby know they have lost the argument and only a small minority would use violence, who are upset about the idea that we exist. All we were doing was exercising free speech.“What’s important is that we get the message out…I’m happy to face that kind of person again. What scares me is the idea of being silenced, that would be more frightening to me than facing any number of physical threats.”There have been worries that animal rights activists might target the planned march this weekend. It is expected that hundreds of people will turn up in support of the group’s aims, which will process through Oxford from Broad Street at noon. Laurie Pycroft, the teenage founder of Pro-Test claimed that the rally is to “show that students, scientists and the public at large will not be cowed by animal extremists.”by Natasha Vashishtlast_img read more

Austrian soy arrives in UK

first_imgNew to the UK market are Soja soya flours and ingredients from Austria. Soja produces gluten- and lactose-free whole soy products and is currently supplying into international bakery and pasta brands.These range from enzyme-active soy flour, Soja Austria Pan, to soy flakes, Soja Austria Flakes. The finely ground soy flour is available in various toasting grades, according to customer requirements.”Compared with the American bean, Soja Austria Pan has a higher enzymatic activity, which will allow British bakeries to produce fluffy toast bread and crispy white breads,” claims the firm. “The warm, dry climate of summer in Austria is ideal for the delicate soy plant. Nutritious soil, clean water and well-chosen seeds allow superior quality soybeans to thrive.”In addition, the company supplies soy fibres and nuts, distributed in the UK through Thew Arnott & Co.The products are guaranteed non-GMO.last_img read more

A speedier solution for molecular biomedical research

first_imgThe recorded spectrogram, however, only contains very indirect information about the molecular structures, making analyzing and identifying those molecules a complex pattern-recognition problem. If the patterns aren’t recognized or previously known, it can take days or months of trial and error to put together an answer, because ordinary computers must make those computations one at a time.Using a quantum system takes advantage of its ability to access and calculate faster, and makes use of a mathematical construct known as Hilbert space and the higher processing power of qubits. One qubit can be two traditional values at once, a pair can be four, and so on. The problem with the current or intermediate quantum computers, though, is that all that computing power accumulates a lot of noise, making the whole calculation inaccurate.Hybrid algorithms have been proven to be an effective bridge to solve for this, so the researchers thought they might work here, too. In the paper, they describe how their hybrid algorithm uses classical statistical methods, like Bayesian machine learning, to cluster and refine the search to correct for errors brought on by the quantum part of the algorithm, leading to the correct molecule.“There are three parts to the paper,” said Sels. “All three ingredients are necessary because if you leave out the first part where we restrict ourselves to these clusters of physical molecules, then basically you’ll start in some place that’s so far away from where you actually want to end up that you’ll be searching for it forever. And then in the last part, the same thing: If you don’t do it cleverly, then the noise levels of your quantum computer will be so high, they’ll just be going in circles — you’ll be randomly searching.”They tested the algorithm using simple molecules that had only four quantum spins and had already been identified, so they knew whether the algorithm worked. The researchers hope to expand the algorithm’s capability so it can analyze and identify more-complex molecules. They also believe the algorithm can be extended to solve for other types of spectroscopic analysis using existing quantum computers.“It probably took us 20 or so years to get to the current stage of development of quantum computing hardware,” Sels said. “The road ahead to quantum computers that can do error correction and are good enough to be plug-and-play devices is presumably equally as long. If we don’t have applications for these intermediate or current state-of-the-art machines, then we might face a quantum winter.”Harvard’s Office of Technology Development has protected the intellectual property associated with this work and is exploring possible commercialization opportunities.This work was supported by the Harvard Quantum Initiative, the National Science Foundation, the Army Research Office, the Harvard-MIT Center for Ultracold Atoms, and the National Heart, Lung, and Blood Institute. Dries Sels is a senior postdoctoral fellow of the Research Foundation – Flanders in Belgium. A process called NMR spectroscopy that is often used to find and identify small molecules in biological samples such as blood and urine has become a powerful diagnostic tool for medical professionals, helping identify biomarkers of specific diseases and disorders.But the technique has its limits, especially when researchers need to identify molecules that haven’t been catalogued already — that is, the vast majority of them.A trio of doctors and medical researchers from Brigham and Women’s Hospital and Harvard Medical School wanted to make this complicated and time-consuming process a lot simpler, and hoped quantum physics could help. They figured that since the basics of NMR, short for nuclear magnetic resonance, is grounded in quantum mechanics, then perhaps a quantum computer could help push the technique beyond the current limits set by using ordinary computer processors to interpret the data.The researchers from the Medical School enlisted a pair of quantum physicists from the Faculty of Arts and Sciences to help. Now, the combination of medical researchers and quantum scientists have published the results of their collaboration — a new algorithm for decoding signals from NMR readings that draws from both quantum computing and classical machine learning — in a new study in Nature Machine Intelligence.The hybrid algorithm does, in theory, just what the researchers hoped. It would reduce a process that can take days for classical computers days into just minutes by using quantum systems that run on only 50 to 100 quantum bits, or “qubits,” the fundamental building blocks on which these computers operate. In other words, the algorithm works on both quantum computers that already exist and the so-called “near-term” quantum computers now being developed. These machines would act as a bridge between the intermediate period of current error- (or “noise-”) prone machines and the error-correcting, perfected versions envisioned to become reality decades from now.The researchers believe the new hybrid algorithm can be one of the first applications for the not-so-distant intermediate computers, helping fill a growing need in practical applications of quantum technology as the hardware catches up with the theory. Quantum computers use the mysterious properties of matter at extremely small scales to greatly advance processing power and perform calculations that are virtually impossible for ordinary computers to solve.In recent years, finding useful applications for existing or near-term quantum computers has been a central challenge for researchers, said Eugene Demler, professor of physics and one of the paper’s co-authors.“We should not just think of applications for perfect quantum computers. We should think of applications of quantum computers for the near future,” Demler said. “It’s important to realize that we can use these non-perfect computers — these noisy, intermediate-scale quantum computers — to already study what’s important for biomedical research.”The algorithm has only just passed the proof-of-concept stage, according to the paper, but it opens a door to possibilities in chemical, medical, and biological research using NMR if it can be expanded beyond the tests the researchers outlined.Take blood, for example, said paper co-author Samia Mora, an associate professor of medicine at the Medical School and a cardiovascular medicine specialist at the Brigham. “We know there are thousands of molecules in the bloodstream, but right now with NMR we probably only measure about 200 [of them],” she said. “In the future, ideally, we would be able to expand this algorithm to be able to solve for this problem of what are these molecules in the bloodstream beyond the ones that we already know.”Doctors could then base treatments, like cancer therapy, off those readings, or they could prescribe preventative measures if a patient has small molecules in his or her blood that correspond with heart disease. The readings could also help in drug discovery or vaccine research.“Having a better understanding of the molecular signatures of diseases or treatments is really very impactful for many areas across many, many different disciplines,” Mora said.Other Harvard researchers who worked on the study included Hesam Dashti, a research fellow at the Brigham and HMS, Olga Demler, an associate biostatistician at the Brigham and assistant professor at HMS, and Dries Sels, Demler’s postdoctoral fellow and the lead author of the study.Sels and Demler had been searching for an opportunity like the one presented in the paper. They wanted a crack at a problem that has real-world applications, is hard for classical computers, yet could be solved using existing and near-term quantum computers. Quantum-assisted NMR spectroscopy checked all the boxes since the readings, called a spectrogram, are put together by measuring a complex set of quantum spins.For example, to get a spectrogram, biological samples are placed inside a machine that has a magnetic field and are then bombarded with radio waves to excite the nuclear magnetic properties in the molecules. The NMR machine reads those spins as different signatures.

After failed Trump romance, France seeks reset under Biden

first_imgPARIS (AP) — U.S. President Joe Biden and French President Emmanuel Macron agreed Sunday to work closely together to fight the coronavirus pandemic and climate change. Their first conversation since Biden’s inauguration aimed at mending ties between the historic allies that frayed under Donald Trump. Biden “stressed his commitment to bolstering the transatlantic relationship” via NATO and the EU. The U.S. and French leaders see eye-to-eye on the importance of international cooperation to fight climate change and COVID-19 and in negotiating with Iran. But Macron’s office said the two wouldn’t shy away from thorny issues like trade disputes or taxing digital companies such as Google or Amazon.last_img
