![]() Further investigations into this uranium deposit discovered uranium ore with a 235Ĭoncentration as low as 0.44% (almost 40% below the normal value). A series of measurements of the relative abundances of the two most significant isotopes of the uranium mined at Oklo showed anomalous results compared to those obtained for uranium from other mines. Thus the French Commissariat à l'énergie atomique (CEA) began an investigation. ![]() Furthermore since fissile material is why people mine uranium, a significant amount "going missing" was also of direct economic concern. This discrepancy required explanation, as all civilian uranium handling facilities must meticulously account for all fissionable isotopes to ensure that none are diverted to the construction of nuclear weapons. Normally the concentration is 0.72% while these samples had only 0.60%, a significant difference (some 17% less U-235 was contained in the samples than expected). In May 1972 at the Tricastin uranium enrichment site at Pierrelatte in France, routine mass spectrometry comparing UF 6 samples from Oklo showed a discrepancy in the amount of the 235 It is estimated to have averaged under 100 kW of thermal power during that time. ![]() Oklo consists of 16 sites at which self-sustaining nuclear fission reactions are thought to have taken place approximately 1.7 billion years ago, and ran for hundreds of thousands of years. Oklo Mine (sometimes Oklo Reactor or Oklo Mines), located in Oklo, Gabon on the west coast of Central Africa, is believed to be the only natural nuclear fission reactor. ![]() Working-class Hongkonger emigrants began arriving in large numbers in the late 1960s. Surviving the ravages of the 1880s, Chinatown became a haven for later waves of emigrants from China in the 20th century. The main dialect spoken in Chinatown then was Hoisan-wa (aka Hoisanese Toisanese in Cantonese and Taishanese in Mandarin), native to the emigrants from Hoisan (aka Toisan in Cantonese and Taishan in Mandarin), Sze Yup, in the Pearl River Delta. In the 1850s, Chinese pioneers, mainly from villages in the Pearl River Delta in Guangdong, began immigrating in large numbers to San Francisco, initially drawn by the California Gold Rush and the building of the first transcontinental railroad, and settling in Chinatown for refuge from the hostilities in the West. Many of the Chinese immigrants who managed to accumulate wealth while living in Chinatown move to the Richmond District, the Sunset District, or the suburbs. According to a study by the San Francisco Planning Department in 2018, 81% of the residents in the neighborhood were Asian. The areas of Stockton and Washington Streets and Jackson and Kearny Streets in Chinatown are almost entirely Chinese or Asian, with blocks ranging from 93% to 100% Asian. In 2015, only 14% of households in the SROs were headed by a person that spoke English fluently. Most residents are monolingual speakers of mutually unintelligible dialects of the Chinese language: historically Hoisanese, now Cantonese and some Mandarin. There are two public housing projects in Chinatown, Ping Yuen and North Ping Yuen. As of 2015, two thirds of the residents lived in one of Chinatown's 105 single room occupancy hotels (SRO), 96 of which had private owners and nine were owned by nonprofits. The median age was 50 years, the oldest of any neighborhood. ĭuring the time from 2009 to 2013, the median household income was $20,000 – compared to $76,000 citywide – with 29% of residents below the national poverty threshold. In the 1970s, the population density in Chinatown was seven times the San Francisco average. It is made of bronze and weighs approximately 600 lb (270 kg).Īccording to the San Francisco Planning Department, Chinatown is "the most densely populated urban area west of Manhattan", with 15,000 residents living in 20 square blocks. ![]() A replica of the Goddess of Democracy used in the Tiananmen Square protest was built in 1999 by Thomas Marsh and stands in the square. Since it is one of the few open spaces in Chinatown and sits above a large underground parking lot, Portsmouth Square bustles with activity such as T'ai Chi and old men playing Chinese chess. Ī major focal point in Chinatown is Portsmouth Square. It is dominated by mixed-use buildings that are three to four stories high, with shops on the ground floor and residential apartments upstairs. The other, Stockton Street (市德頓街), is frequented less often by tourists, and it presents an authentic Chinese look and feel reminiscent of Hong Kong, with its produce and fish markets, stores, and restaurants. One is Grant Avenue (都板街), with the Dragon Gate ("Chinatown Gate" on some maps) at the intersection of Bush Street and Grant Avenue, designed by landscape architects Melvin Lee and Joseph Yee and architect Clayton Lee Saint Mary's Square with a statue of Sun Yat-sen by Benjamin Bufano a war memorial to Chinese war veterans and stores, restaurants and mini-malls that cater mainly to tourists. Within Chinatown there are two major north–south thoroughfares. San Francisco's Chinatown is also renowned as a major tourist attraction, drawing more visitors annually than the Golden Gate Bridge. Recent immigrants, many of whom are elderly, opt to live in Chinatown because of the availability of affordable housing and their familiarity with the culture. There are two hospitals, several parks and squares, numerous churches, a post office, and other infrastructure. Chinatown is an enclave that has retained its own customs, languages, places of worship, social clubs, and identity. Since its establishment in 1848, it has been important and influential in the history and culture of ethnic Chinese immigrants in North America. It is also the oldest and largest of the four notable Chinese enclaves within San Francisco. The Chinatown centered on Grant Avenue and Stockton Street in San Francisco, California, ( Chinese: 唐人街 pinyin: tángrénjiē Jyutping: tong4 jan4 gaai1) is the oldest Chinatown in North America and one of the largest Chinese enclaves outside Asia. Inv_scale_factor_x = original_width/new_width Inv_scale_factor_y = original_height/new_height Original_height, original_width = image_matrix.shape Output_image = numpy.zeros((new_height, new_width), dtype=image_matrix.dtype) """Perform a pure-numpy linear-resampled resize of an image.""" import mathĭef resize_linear(image_matrix, new_height:int, new_width:int): I offer this under Apache or MIT license at the discretion of the user. If you're only rescaling smaller images, it should be fine. It does not make good use of Numpy and, thus, is not fast, especially for large images. It has three advantages over the above: (1) it will accept arbitrary resolutions, even non-power-of-two scaling factors (2) it uses pure Python+Numpy with no external libraries and (3) it interpolates all the pixels for an arguably 'nicer-looking' result. These solutions are all respectable, so I offer this only for completeness. It looks like the answers so far fall into one of a few categories: Stumbled back upon this after a few years. It's the fastest way to do this that I've found. This method uses the equivalent of max pooling. Small_image = large_image.reshape((1, output_size, bin_size, Small_image = large_image.reshape((3, output_size, bin_size,įor grayscale images just change the 3 to a 1 like this:Ĭhannels first ordering # large image is shape (1, 128, 128) Small_image = large_image.reshape((output_size, bin_size,Ĭhannels first ordering # large image is shape (3, 128, 128) The following examples downsample from 128x128 to 64圆4 (this can be easily changed).Ĭhannels last ordering # large image is shape (128, 128, 3) This method only works when the input dimensions are a multiple of the output dimensions. Like with most options, there is no "best" option in the sense that for every resize schema, there are scenarios where one strategy can be preferred over another.įor people coming here from Google looking for a fast way to downsample images in numpy arrays for use in Machine Learning applications, here's a super fast method (adapted from here ). INTER_LANCZOS4 - a Lanczos interpolation over 8x8 pixel neighborhood.INTER_CUBIC - a bicubic interpolation over 4x4 pixel neighborhood.But when the image is zoomed, it is similar to the It may be a preferred method for image decimation, as it gives moire’-free INTER_AREA - resampling using pixel area relation.INTER_LINEAR - a bilinear interpolation (used by default).INTER_NEAREST - a nearest-neighbor interpolation.Especially since you scale down the image, and the size of the original image is not a multiple of the size of the resized image. An important aspect is the interpolation parameter: there are several ways how to resize an image. Here img is thus a numpy array containing the original image, whereas res is a numpy array containing the resized image. Res = cv2.resize(img, dsize=(54, 140), interpolation=cv2.INTER_CUBIC) ![]() ![]() Yeah, you can install opencv (this is a library used for image processing, and computer vision), and use the cv2.resize function. ![]() We need now a more radical social science research with children in which children themselves learn to reflect upon their own conditions, so that they can gradually begin to take greater responsibility in creating communities different from the ones they inherited. We cannot rely upon the traditional approach of social science which observes children's lives and reports it to policy makers in the hope that they will improve children's conditions. I believe that much of what people in this conference find disturbing about the quality of children's lives in cities today will need to be changed by those same children. I have been asked in this conference to provide a link in my talk between those who are talking about the ecology of children in cities and those, who like Anna, are try- ing to improve the lives of children. Her "Passage House" program is a superb example of the change from an entirely "protectionist" approach to a more "empowering" approach to working with children living in difficult circumstances. It was appropriate to open the conference with a talk from Anna Vasconcelos. The paper considers the reasons why this might be the case and comments on the distinction, apparent in two schools, between what was seen as ‘normal’ and ‘special’ outdoor activity. Drawing on data from interviews and observations conducted in four schools, it is suggested that the teachers missed many of the opportunities afforded by the outdoor environment to enhance children's learning. This paper discusses the findings of a research project that aimed to document the current use of the outdoors by a group of early years teachers working in South Wales. While the framework is currently being piloted across Wales, full implementation will not take place until 2010 for many schools, then, this is a time of transition. ![]() The Foundation Phase framework promotes a play‐based approach to children's learning in both indoor and outdoor contexts and places children's well‐being and their personal and social development at its core. In 2001, the Welsh Assembly Government announced proposals for a Foundation Phase for children aged three to seven years. ![]() ![]() The assessment of this initiative, carried out by the undergraduate students during the pilot study showed that there is a distinct need for connecting real spaces with technology and for familiarity with the tools that help pupils visualise the space and that Google SketchUp could be an effective tool that is easily applied to this project and can enrich geography lessons for pupils in upper primary and lower secondary education. The aim of the project was to create awareness of spaces and their functions, and to redesign those spaces using Google Sketch up according to criteria relating both to the environment and the needs of pupils and their education. The educational project involving the design of a school yard using Google SketchUp, presented in this paper, was originally designed and implemented by undergraduate students at the Department of Primary Education of the National and Kapodistrian University of Athens (UoA) in the context of their studies in the “Teaching Geography with ICT†course. Premiere Elements 14 also adds places and event support as well as Guided Edits that allow you to perform tasks such as popping colors out in a scene, creating slow-motion and fast-motion effects, and more. Searching features have also been enhanced, adding facial recognition to allow you to find photos of specific people later, view photos and videos on a map based on where they were taken, and organize photos and videos based on the events they capture. ![]() A new Quick Edit mode also allows you to rotate and make quick fixes a lot faster than before, and Elements can analyze subject, color, and lighting to provide tailored effects for your photos. Selection tools have also been enhanced to provide more granularity for selecting fine details, and Guided Edits take you through common tasks step by step, such as adding a sense of motion to your photos or resizing them to a specific frame size. Photoshop Elements 14 now includes tools for removing camera shake and haze, bringing over some of the features from the 2015 Creative Cloud update to Photoshop CC. ![]() ![]() Freshly updated new versions of Adobe Photoshop Elements 14 ($100) and Adobe Premiere Elements 14 ($100) gain several handy new features bringing them a bit closer to their much more powerful siblings, while also refining the user interface for more ease of use. If you’re looking for a photo or video editing solution and don’t want to break the bank with Adobe’s full “pro” editions of Photoshop or Premiere, the good news is that you can still stay in the Adobe family with its reasonably powerful “prosumer” Elements editions. ![]() ![]() Stehman-Breen wouldn’t say how long the new financing is expected to last, or even if the money would be enough to start testing the company’s first therapies in clinical trials. Chroma’s other scientific founder is Luke Gilbert from the University of California, San Francisco. ![]() The firm is based on research from six scientific founders, including three CRISPR gene editing experts in Massachusetts: Keith Joung from Massachusetts General Hospital, David Liu from the Broad Institute of MIT and Harvard, and Jonathan Weissman from the Massachusetts Institute of Technology.Ĭhroma previously acquired the Italian biotech startup Epsilen Bio, founded by Angelo Lombardo and Luigi Naldini from the San Raffaele Telethon Institute for Gene Therapy, who became scientific founders of Chroma. Chroma has about 80 employees and Stehman-Breen said she plans to hire more, but wouldn’t say how many. The new financing comes at a time when many biotech startups are finding it difficult to raise money needed to keep the lights on, forcing some to downsize or even close altogether. ARCH Venture Partners, a Chicago-based biotech venture capital firm, was an investor in both Aera and Chroma.Ĭhroma previously raised $125 million in 2021. In February, investors at GV co-led a $193 million financing for Boston-based Aera Therapeutics, which is developing a new method for delivering gene editing therapies into hard-to-reach parts of the body. The new financing came from more than a dozen investment firms and was led by GV - formerly Google Ventures, the investment arm of Alphabet. But some scientists have cautioned that the complex molecular machines required to make epigenetic editing work in a human ― rather than cells in a petri dish or a mouse ― suggest that it could be many years before companies are able to prove that the technology is safe and effective in people. ![]() Chief scientific officer Vic Myer added the technology might be able shut down the production of viruses that chronically infect human cells.Įpigenetic editing has excited some researchers who hope it will be a safer way of boosting the output of protective genes and blocking potentially harmful ones without making any alterations or incisions to DNA itself. Catherine Stehman-Breen wouldn’t say what diseases Chroma is focused on, although she noted that epigenetic editors could be useful for engineering cell therapies or tuning the expression of multiple genes involved in metabolic disease. *** You are running in headless mode.Ĭrash Annotation GraphicsCriticalError: |: glxtest: libpci missing (t=0.323898) : glxtest: libpci missingĬrash Annotation GraphicsCriticalError: |: glxtest: libpci missing (t=0.323898) |: glxtest: libGL.so.1 missing (t=0.32393) : glxtest: libGL.so.1 missingĬrash Annotation GraphicsCriticalError: |: glxtest: libpci missing (t=0.323898) |: glxtest: libGL.so.1 missing (t=0.32393) |: glxtest: libEGL missing (t=0.323941) : glxtest: libEGL missingĬrash Annotation GraphicsCriticalError: |: glxtest: libpci missing (t=0.323898) |: glxtest: libGL.so.1 missing (t=0.32393) |: glxtest: libEGL missing (t=0.323941) |: No GPUs detected via PCI (t=0. ![]() ![]() 11-inch iPad Pro, 12. iOS 13.6 adds support for digital car keys, introduces audio stories in Apple News+ (US only), and contains a new symptoms category in the Health app.iPhone 11 Pro Max, iPhone 11 Pro, iPhone XS Max, iPhone XS.It comes with a bunch of new features such as CarKey.
