Thousands of Swedes got false positive COVID-19 result due to test kit fault from BGI Genomics (華大基因)

  About 3,700 people in Sweden were told in error that they had the coronavirus due to a fault in a COVID-19 testing kit from China, the Public Health Agency said on Tuesday. The kit from BGI Genomics could not distinguish between very low levels of the virus and a negative result, the agency said.  The kits were used by people in Sweden conducting at=home tests between period March and August, the agency said. 'The supplier must adjust the performance that is required for this test to be used,' Karin Tegmark Wisell, the head of its microbiology department, said "The two laboratories have analyzed samples from a total of ten regions in Sweden, of which nine have received incorrect test results. This applies to Stockholm, Västra Götaland, Gävleborg, Västerbotten, Västmanland, Dalarna, Västernorrland, Sörmland and Blekinge," the agency said in a statement. The agency also noted that a majority of the people that received the false positive test results "have ...

IMX290 vs IMX462 new planetary CCD

  IMX462 has lower readout noise, and very high QE in near Infrared spectrum. by using 850nm filter, this CCD can be used as NIR only camera. monochrome ( ASI290MM) is better than color version(ASI178MC, ASI294MC), for solar astrophotography: Extended IR response: Advantage for planetary astro IMX327 is very similar to IMX462, except with a lower 60 FPS Jupiter  using CH4 filter astrosurf Amateurastrophotography Astrowl

Terrain Relative Navigation (TRN) and Dual LIDAR-based Navigation

  from Prof. Dr. ir. Maarten Uijt de Haag, he introduces pros and cons of using dual LIDAR Andrew Johnson's presentation :   this TRN has been in use since Mars MSL mission in 2011, and advance further  in Mars 2020  The Mars 2020 mission is facing the most challenging landing yet on the Red Planet. It will touch down on Feb. 18, 2021, in Jezero Crater, a 28-mile-wide (45-kilometer-wide) expanse full of steep cliffs, boulder fields and other things that could boobytrap the landing. A new technology called Terrain Relative Navigation (TRN) will allow the spacecraft to avoid hazards autonomously. This improves the landing accuracy from previous 1 to 2 km to now less than 60 m  The Lander Vision System (LVS) for M2020  is representative of the current state of the art in map-relative localization for TRN. Orbital reconnaissance imagery of Mars is available with a resolution of 30 cm/pixel from the HiRISE camera; this is processed into maps at two resoluti...

smart city projects in HK

  pcmarket presentation smartcity.gov.hk   Our policy objectives to pursue smart city development are to – (a) make use of innovation and technology (I&T) to address urban challenges, enhance the effectiveness of city management and improve people’s quality of living as well as Hong Kong’s sustainability, efficiency and safety; (b) enhance Hong Kong’s attractiveness to global businesses and talents; and (c) inspire continuous city innovation and sustainable economic development. We have commissioned a comprehensive consultancy study which has made short-, medium- and long-term recommendations in six major areas, namely: “Smart Mobility”, “Smart Living”, “Smart Environment”, “Smart People”, “Smart Government” and “Smart Economy”. Having regard to our city challenges, unique local situation and strengths and opportunities ahead, we have mapped out in this document our smart city development plans in the next five years, and beyond.

what is in a cup of coffee

    98.75% is water Green coffee contained about 6–7% of sucrose as soluble sugars and low amount of glucose. The soluble sugars of roasted coffee were sucrose, fructose, and glucose The main constituents of coffee are caffeine, tannin, fixed oil, carbohydrates, and proteins. It contains 2–3% caffeine, 3–5% tannins, 13% proteins, and 10–15% fixed oils. In the seeds, caffeine is present as a salt of chlorogenic acid (CGA). Also it contains oil and wax.   Caffeine 2-Ethylphenol - crema Quinic acid - acidic profile   3.5 Dicaffeoylquinic Acid   Sulfur-containing compounds, including 2-furfurylthiol.

QHY Minicam 5F

 the manual and software are located here   Software installation(for Windows): 1. install "System Driver" first. When this installation complete, use the USB cable to connect the camera to your computer. Windows should detect and show up in device manager. 2. install EZPlanetary for video capture. Run and test if you capture video with the camera when you install "System Driver", it will automatically install "Native WDM Driver" at the same time. 3. if you intend to use SharpCap, SharpCap will use this "Native WDM Driver" to control gain and exposure etc. Please use SharpCap v2.0 or newer, which has better support on Minicam 5F 4. if you need  to do streaming video, eg capture video by EZPlanetary, and stream the video in SharpCap, install "Broadcast WDM Driver". you may also refer to QHY5-II ( which uses same CCD sensor) page to understand more the details of each installation step For image capture, install EZCAP-QT, or you may insta...

PolyU develops Mars Camera

      PolyU is to design and produce a Mars Landing Surveillance Camera (Mars Camera), which will be located on the outside top surface of the Mars Lander. The Mars Camera will monitor the deployment status of the Mars Rover with respect to the status of the solar panel, antenna, as well as the rover's movement. The information is critical for the successful movement of the Mars Rover onto the Mars surface. To capture ultra-wide angle images on Mars for scientific research, the Mars Camera has to have a wide field of vision with low distortion optics within the little allowable payload, but at the same time be able to withstand extreme temperature variation, mechanical impact and vibration within the little available mass. What’s more, high reliability is required under the extreme space travel environment     facebook watch digital manufacturing in poly u  It is collaboration between The Hong Kong Polytechnic University (PolyU) and the China Aca...

vaccine development of novel coronavirus

Around the world, more than 30 vaccines — out of a total of more than 165 under development — are now in various stages of human trials. Currently, eight vaccines have entered the final phase of mass human testing, including ones produced by Moderna in the United States, Oxford University and AstraZeneca in Britain and several Chinese companies. Some of those Chinese companies have been accused of cutting corners themselves. One offered the vaccine to employees at the national oil company, while another has teamed up with the People’s Liberation Army to conduct human trials. The Russian vaccine uses two strains of adenovirus that typically cause mild colds in humans. Scientists genetically modified them to cause infected cells to make proteins from the spike of the new coronavirus, officials have said. The approach is similar to the one used in a vaccine developed by Oxford University and AstraZeneca that is now undergoing Phase III tests in Britain, Brazil and South Africa. hk01  ...

TJS 通訊技術試驗

 TJS 系列很特殊,通信技术实验卫星只是个名字,其实是各种各样的同步轨道特殊用途卫星。你只要看到tjs,就要知道这是同步轨道特殊用途的卫星,大多数不是去验证通信技术的。tjs-1据信是一颗拥有32米可展开环形天线的电子信号监听卫星。类似当年的长空一号的作用,专门监听收集美国佬的电子信号 ,还有日韩台的tjs-2据信是一颗基于风云4号平台的早期预警卫星。tjs-3,tjs-4还不清楚具体用途。这颗tjs-5显然是一颗和tjs-2类似的以风云4号平台为基础的早期预警卫星。
