Ground control points (GCPs) are points on the Earth's surface that can be used to geo-reference remote sensing satellite data. The identification of GCPs can be achieved either by on-ground inspections or by processing of aerial/satellite data. The first option ensures the highest geolocation accuracy, but it can require long turnaround times and high logistical costs. Moreover, in situ inspections can be impossible in certain areas of the world (e.g., because of difficult access or geopolitical issues). Hence, there is a strategic interest in the development of services that can be used to deliver accurate remote sensing of GCPs. Ongoing satellite missions—such as the Constellation of Small Satellites for Mediterranean Basin Observation (COSMO-SkyMed, or CSK) and TerraSAR-X (TSX)—are providing high-resolution synthetic aperture radar (SAR) data in the X-band (i.e., a segment of the microwave radio spectrum used for communications). The availability of this data is fostering the development of methods and services for extracting GCPs with sub-metric accuracy. Such endeavors are also appealing for both civilian and military purposes. Conceptually, SAR-based GCP-extraction consists of two steps. First, the same local feature is identified in a number of SAR images and its range/azimuth coordinates are determined. The second step involves the use of spatial triangulation (stereo analysis) and inversion methods for spatial 3D position retrieval from the 2D radar coordinates (range/azimuth). To boost the geolocation accuracy, SAR images must be acquired from different lines of sight, with intersection angles typically much wider than 10°. The lines of sight can even be in completely opposite directions,1 but this usually hinders the ability to perform the GCP identification in a fully automatic manner. In addition, many robust algorithms—such as the Scale-Invariant Feature Transform (SIFT), Speeded Up Robust Features, and Binary Robust Independent Elementary Features methods—have been proposed for the automatic identification and matching of local invariant features.2 These algorithms, however, were originally developed for optical photographs and images, and do not perform well on images affected by multiplicative noise sources (e.g., speckle in SAR data). To mitigate the effect of speckle noise, many adaptations of local-features-matching algorithms have thus been proposed in the recent literature, including SAR-SIFT3 and SIFT-Octave.4 These algorithms, however, only have satisfactory performances with narrow intersection angles. In this study,5 we propose a further adaptation to the existing algorithms. Our approach is specifically designed to ensure robustness and accuracy in the fully automatic detection of bright isolated targets (e.g., steel light poles or towers), even when dealing with opposite-side-looking data. In particular, we have selected the popular Harris algorithm6 as the detector. We chose this algorithm because recent studies4, 7 provide a consensus that it is the most stable and robust-to-noise algorithm for corner detections from SAR images. Furthermore, we opted for a solution that combines simplicity and robustness. This is different from previously proposed descriptors, which typically consist of high-dimension feature vectors (e.g., 128 for SIFT). We derive the properties of our descriptor from radar fragments centered on the candidate GCP corner. We also perform mild geocoding, through the use of low-resolution digital terrain models (DTMs) that are available over the area of interest (e.g., the Shuttle Radar Topography Mission or radargrammetric DTMs). In addition, the performance of our matching algorithm can be enhanced by limiting the search space (as demonstrated by previously proposed solutions, in which DTM and orbit information are used7 or that involve a manual pre-registration8). Once we have identified the GCP candidates and have estimated their fractional line/pixel coordinates from each SAR image, it is necessary to convert those coordinates into sensor–target distances and azimuth coordinates. In our approach, we must also account for the atmospheric propagation delay (APD)—i.e., delays in satellite-to-Earth communications caused by the atmosphere—for computation of the slanted range distance. We thus use numerical weather modeling9 to precisely estimate the APD. In the final part of our technique, we invert range/Doppler equations to infer the 3D geographic coordinates of the candidate GCPs. To improve the accuracy and confidence level, we use multiple scenes (with different look-angles) and we use the least-squares method to solve the over-determined system of equations. Although automatic GCP-extraction tools have previously been successfully verified on TSX data,10 such methods have not yet been tested on CSK images. We have therefore focused on assessing the performance of our algorithm for the processing of CSK data. According to the results from our earlier study,11 a preliminary timing recalibration is required for CSK images. This step is necessary for removing systematic geolocation biases in both range and azimuth directions. In this work, we conducted our experimental analysis for the Pisa area (Italy), for which consistent data takes of radargrammetric enhanced spotlight images are available in the CSK archive. An example of a GCP, in the Pisa urban area, which we automatically detected with our algorithm is shown in Figure 1. The outcomes of our analyses prove that our designed tool is capable of automatically identifying GCPs from CSK data and estimating their geographic position with sub-metric accuracy. In addition, as part of a differential global positioning system campaign, we have computed geolocation errors for a number of vertical isolated targets. In summary, we have developed a new algorithm for the automatic detection of ground control points in remotely sensed SAR datasets. We have based our tool on the popular Harris algorithm, and have thus designed a simple, robust, and accurate algorithm. We have also successfully tested our approach on data from the COSMO-SkyMed satellite for an urban area and have verified that it can be used to estimate the geolocation of GCPs, with sub-metric accuracy. In the next stage of our work we will assess the performance of the tool over mountainous areas, i.e., where radar image distortions are expected to hinder the visibility of GCPs (depending on the orientation of the slopes and the viewing geometry of the satellite sensors). This study was carried out within the framework of the 3D IMINT project (PRNM Contract 10444, 30-12-2013). CSK products, under a license from the Italian Space Agency, were used for this project.

Oakbrook Terrace, Ill. (April 24, 2017) -- Though transmission of malaria was wiped out in the United States decades ago and infections are falling in parts of the developing world, malaria hospitalizations and deaths in the U.S. appear to be far more common than generally appreciated as a steady stream of travelers returns home with the dangerous mosquito-borne disease. That's the key finding from a new study published today in the American Journal of Tropical Medicine and Hygiene that shows malaria led to a count of hospitalized patients and deaths that easily eclipsed other travel-related illness and generated about half a billion dollars in healthcare costs in the U.S. over a 15-year period. "It appears more and more Americans are traveling to areas where malaria is common and many of them are not taking preventive measures, such as using anti-malarial preventive medications and mosquito repellents, even though they are very effective at preventing infections," said Diana Khuu, PhD, MPH, a scientist at the University of California, Los Angeles, and the lead author of the study, which included contributions from the U.S. Centers for Disease Control and Prevention (CDC). Khuu and her colleagues looked for malaria patients in a database maintained by the federal Agency for Healthcare Research and Quality (AHRQ) that tracks hospital admissions nationwide. The researchers found that between 2000 and 2014, about 22,000 people were admitted to U.S. hospitals due to complications from malaria. Moreover, 4,823 patients were diagnosed with severe malaria, which means they suffered from problems like renal failure, coma or acute respiratory distress that significantly increase the risk of death, and 182 of these patients died. The study showed that malaria hospitalizations were more common in the U.S. than hospitalizations for many other travel-associated diseases. For example, during the same period, dengue fever, which is common in Mexico, Puerto Rico, and throughout Latin America, and has caused small, local outbreaks in south Florida and Texas, generated, on average, 259 hospitalizations a year compared with 1,489 for malaria. According to the study, malaria hospitalizations are quite common in the U.S., and the associated burden from these cases is substantial. The researchers found that the average cost per patient was about $25,800 and that the total bill for treating malaria patients in the U.S. from 2000 to 2014 was about $555 million. Overall, the scientists estimated that each year there are about 2,100 people in the U.S. suffering from malaria, since about 69 percent require hospital treatment. That case count would exceed the high end of the official CDC estimate of 1,500 to 2,000 cases per year. Khuu attributed the difference to the fact that CDC's malaria count is based on reports submitted to the agency by hospitals or physicians, and hospital admission records that were used in her study may capture additional cases that have not been reported to CDC. While those admissions' records did not include travel history, the researchers believe the malaria infections they documented most likely were acquired during travel to parts of Africa, Asia, and Latin America, where malaria is still common. Over the last 15 years a blitz of malaria interventions that include insecticide-treated bednets and increased access to highly effective malaria drugs has been accompanied by an estimated 37 percent drop in malaria incidence and a 60 percent drop in malaria deaths globally. Meanwhile, although malaria was eliminated from the U.S. in the 1950s, there are sporadic reports of locally-acquired malaria infections, presumably caused by a mosquito that either fed on an infected traveler or hitched a ride on a flight or ship coming from a malaria-endemic region. But Khuu noted that mosquitoes capable of carrying malaria are common in many parts of the U.S., and that increases in the number of travelers coming home with the disease increases the risk of malaria re-establishing itself in the U.S. According to the study, the majority of malaria hospitalizations occurred in the eastern U.S. in states along the Atlantic seaboard. Malaria's last domestic stronghold was in the Southeast. Also, the study found that men accounted for 60 percent of the malaria-related hospital admissions. The researchers believe the overrepresentation of males in the U.S. malaria count may indicate that men are less likely to seek travel advice or, when they do, less likely to adhere to recommendations for preventing infections, like taking an anti-malarial preventive medication and using a mosquito repellent. The researchers noted that most of the deaths and severe disease appeared to be linked to infections with the malaria parasite known as Plasmodium falciparum, which is responsible for the vast majority of malaria deaths and severe disease worldwide. But the study found that in almost half of the malaria-related hospitalizations there was no indication of parasite type, though Khuu pointed out that information can be obtained via a relatively simple blood test. Khuu noted that identifying the parasite causing the infection can be crucial for determining treatment and prognosis. For example, patients sickened by the P. vivax and P. ovale parasites can appear to be fully recovered. But unlike the case with P. falciparum malaria, the P. vivax and P. ovale parasites can enter a dormant stage and then, after treatment, re-emerge to cause a relapse of the disease. According to the CDC, preventing relapse requires both treating the acute infection and, in addition, a course of a drug called primaquine. "Hospitalizations in the United States from malaria remind us that we live in an interconnected world," said ASTMH President Patricia F. Walker, MD, DTM&H, FASTMH. "For this reason, the U.S. must continue to invest in tropical medicine research efforts and programs, even for diseases like malaria that we don't think of as American diseases. To get the job done, we need a strong NIH a strong CDC, and commitment to military research."

STUTTGART, 04-May-2017 — /EuropaWire/ — Two exciting weekends for the brand with the three-pointed star, as Valtteri Bottas wins his first Grand Prix in Russia and the new DTM season gets underway at Hockenheim with a milestone for Mercedes-AMG Motorsport, namely the 400th race in the DTM/ITC. This is what happened: Weekend’s results & facts StatAttack – Russia: Four races, four victories – the Sochi Autodrom continues to be a happy hunting ground for the Silver Arrows. At one point, however, it looked as if the Mercedes-AMG Petronas Motorsport Formula One Team were not going to repeat their victory of the previous year. For the first time this season, neither of the two Silver Arrows drivers qualified for the front row of the grid. Valtteri missed out on P2 in a tense qualifying session by just one tenth of a second. On the day of the race, however, the tables were turned: Valtteri got off to a stunning start, overtook both Ferraris and proceeded to claim a first ever grand prix victory. Finnish successes: With this maiden win in the highest echelon of motor racing, Valtteri joins an illustrious band of fellow countrymen: Keke Rosberg (world champion 1982), Kimi Räikkönen (world champion 2007), Mika Häkkinen (world champion 1998, 1999) and Heikki Kovalainen. Four of the five victorious Finns won at least one race in a Mercedes-powered car: Häkkinen (20 wins with a Mercedes engine), Räikkönen (nine wins with a Mercedes engine), Kovalainen (one victory with Mercedes engine) and now Bottas. So far, eight Finns have competed in a grand prix, five of whom won at least once and three of whom went on to become world champions. It took Valtteri precisely 81 grands prix before he at last ascended the top rung of the podium. Prior to that, he had made eleven podium appearances as the runner-up or third-placed contestant. Show run in Budapest: Valtteri did not have much opportunity to celebrate after his first grand prix victory. Just one day later, he was sitting in the cockpit of a Silver Arrow doing a demo run through the streets of Budapest – a fitting way to mark a maiden F1 victory. Mercedes-AMG DTM driver Robert Wickens was also in Budapest on Monday, assiduously carving out donuts in a Mercedes-AMG C 63 DTM. “Thank you, Budapest,” said Robert afterwards. “There were so many people there. What a great day!” The Hungaroring in Budapest will be hosting both the DTM (16th – 19th June) and Formula One (28th – 30th July) this season. Podium in Monza: Another race weekend and another podium for Maximilian Günther. On the second race weekend of the FIA Formula 3 European Championship at Monza, the 19-year-old registered his second Top Three finish of the campaign. The test and substitute driver for the Mercedes-AMG Motorsport DTM Team came third after starting from sixth on the grid. The race was won by Callum Ilott, his second victory of the season in a Mercedes-powered car. “Standing on the podium in the home race for my team was something special,” said Max. “I am now looking forward to next weekend when I will be accompanying the Mercedes-AMG Motorsport DTM Team to Hockenheim. It will be a great experience for me!” On Saturday, Mick Schumacher made his first Formula 3 podium appearance after finishing third in the second race. 30th win in general classification for the Mercedes-AMG GT3: Ryan Dalziel (SCO) and David Morad (CAN) driving a Mercedes-AMG GT3 won the second race of the SprintX event, part of the Pirelli World Challenge held in the US state of Virginia. This latest success is the 30th general class victory for a Mercedes-AMG GT3 since the car made its debut in 2016. The one-hour race was a first outing for Morad as a member of the CRP Racing squad in the Pro class. The Pro/Am class was won by Jeroen Bleekemolen (NED) and Tim Pappas (USA), also in a Mercedes-AMG GT3. In addition to passing the 30-victory mark, Mercedes-AMG Customer Racing reached another milestone in April as the Mercedes-AMG GT3 and its predecessor (SLS AMG GT3) notched up a 200th victory in various series around the world, including Australia, Asia, Europe and North America. Class victory in the International GT Open: The Mercedes-AMG GT3 registered two class wins in the curtain-raiser to the 2017 International GT Open at Estoril. The Brazilian duo of Marcio Basso and Fulvio Figueiredo (Team Sports & You) left the Am class opposition standing in the first of two races in Portugal. Runners-up were Alexander Hrachovina and Martin Konrad (AUT) of MS Racing. In the second race, it was Hrachovina and Konrad who crossed the finish line first. Second and third in the class were the two Mercedes-AMG GT3s entered by Sports & You driven by António Coimbra and Luis Silva (both POR) and by Basso and Figueiredo. Podium success in the DMV GTC: Bruno Stucky driving an SLS AMG GT3 entered by ANTeam finished second in his class in the two DMV GTC races (general classification P4 and P3) hosted by the city of Dijon in France. In Race 2, Josef Klüber in the number 5 Mercedes-AMG GT3 entered by équipe vitesse was class runner-up. In the concluding Dunlop 60 race (i.e. 60 minutes in length), Klüber and Marc Asbeck (GER) in the number 15 Mercedes-AMG GT3 entered by BLACK FALCON once again finished second and third in their class. Uli, the season is finally upon us. How are you feeling in the run-up to Hockenheim? Ulrich Fritz: Basically, I’m feeling good. But there is always an element of uncertainty. Sure, we tested here four weeks ago, but you never know what the opposition were actually revealing and how many aces they have up their sleeve. I think we have done our homework, and the team as well as the drivers are motivated right down to their fingertips. But the tension is definitely tangible. It is exactly four years since Mercedes found out at Hockenheim that their car was not competitive. Do you have that fear in the back of your mind when you embark on a new season after the car has undergone major development? Ulrich Fritz: Let’s put it this way: the past is always valuable as a source of learning, and I think we now understand the things that didn’t go as they should at the time. But we should not be approaching Hockenheim in fear and trepidation of the first qualifying round. Thoughts of that kind would be very counterproductive. What matters is that everyone in the team can say of themselves that they have done their best. You can’t ask for more than that, anyway. What are you most looking forward to this season? Ulrich Fritz: I have the general impression that the DTM is currently on the up. You can also feel the energy flowing from everyone involved that you want to feel as you go into a new season. Over the winter, we agreed on a lot of good things that should make the racing even more exciting. You will already have heard a lot about the new tyres and the extra horsepower, but I’ll also be interested to see how the spectators react to the whole trackside experience and the innovation with the open garages. ARD have also come up with some good ideas regarding the TV transmission. Ex-champions and motorsport celebrities as co-commentators is going to be great for the fans and certainly entertaining. So I think we’re all heading in the right direction. #Message: After his first Grand Prix victory in Russia, Valtteri Bottas sent a message to his fans, thanking them for their support over recent years. #F1explained: Have you ever wondered what goes on at the team’s section of the pit wall? Who sits where and what job have they been assigned? Sporting Director Ron Meadows reveals the secrets of the pit wall… #ReadyToRace: The Mercedes-AMG Motorsport DTM Team is ready for the new season! We have put together short videos introducing each of the drivers and getting their insights on the forthcoming season. #NoRegrets: Just before the 2017 season gets off the ground, we look back at the previous campaign. But not just that: our documentary provides a glimpse behind the scenes at Mercedes-AMG Motorsport DTM Team and shows how the drivers get on with each other.

The TIME SCALE project will bring closed regenerative life support system (CRLSS) to the next level by further development of the European Modular Cultivation System (EMCS). The EMCS has been successfully operated on the International Space Station (ISS) for 7 years with rotors allowing scientific research under Moon and Mars gravity exposures in addition to microgravity conditions. The EMCS modular design provides the possibility to replace the individual subsystems including the entire rotor system. The TIME SCALE project main objective is to develop an EMCS Advanced Life Support System Breadboard (EMCS ALSS BB) and demonstrate the operational capability for the ISS. The EMCS rotor baseplate will provide generic interfaces to several compartments of a CRLSS such as higher plants (crops), algae bioreactors and mouse. Scientific knowledge on whole higher plant (crop) physiology and fundamental processes under Moon and Mars gravity conditions are essential to ensure a safe and reliable food supply in future space exploration and integration of higher plants into a CRLSS. As part of the project an EMCS crop cultivation system will be developed and tested. The closed water and nutrient management research and development will include solution for challenges such as lack of thermal convection and the need of optimised technology (e.g. ion specific sensors) to monitor nutrients available for plants. Remote sensing diagnosis of plant health will be implemented using sensors and imaging techniques and Selected Ion Flow Tube Mass Spectrometry (SIFT-MS). Knowledge and technology on nutrient and water recycling and early warning for crop suboptimal growth conditions has significant terrestrial relevance for greenhouse systems. The TIME SCALE project bring together Universities and SMEs with the state of the art knowledge and experience needed to develop the EMCS ALSS BB for ISS and has the capacity to utilise the gained knowledge and concepts for terrestrial application.
