If it appears a disease outbreak is likely, local health officials will quarantine the sick animals, saving the remaining livestock and possibly preventing the next COVID-19-type outbreak.</p> <p>Having already achieved significant success in Thailand, with a network of 20,000 farmers helping to detect and control disease outbreaks, PODD is looking to expand its operations to Cambodia, India, Indonesia, Laos, Uganda and Vietnam over the next three years.</p> <p>BloodCounts! - an international consortium of scientists, led by Professor Carola-Bibiane Sch枚nlieb from Cambridge鈥檚 Department of Applied Mathematics and Theoretical Physics (DAMTP) that has developed an innovative infectious disease outbreak detection system, was one of two second-prize winners, each awarded 拢1 million in pledged funding.</p> <p>Developed by Dr Michael Roberts and Dr Nicholas Gleadall, the BloodCounts! Solution uses data from routine blood tests and powerful AI-based techniques to provide a 鈥榯sunami-like鈥 early warning system for new disease outbreaks.</p> <p>鈥淪ince the beginning of the pandemic I have been developing AI-based methods to aid in medical decision making for COVID-19 patients, starting with analysis of Chest X-ray data,鈥 said Roberts, who is affiliated with DAMTP and the Cambridge Mathematics of Information in Healthcare (CMIH) Hub. 鈥淓choing the observations made by the clinical teams, we saw profound and unique differences in the medical measurements of infected individuals, particularly in their full blood count data. It is these changes that we can train models to detect at scale.鈥</p> <p>Unlike many current test methods, their approach doesn't require any prior knowledge of a specific pathogen to work, instead, they use full blood count data to exploit the pathogen detecting abilities of the human immune system by observing changes in the blood measurements associated with infection.</p> <p>As the full blood count is the world鈥檚 most common medical laboratory test, with over 3.6 billion being performed worldwide each year, the BloodCounts! team can rapidly apply their methods to scan for abnormal changes in the blood cells of large populations - alerting public health agencies to potential outbreaks of pathogen infection.</p> <p>This solution is a demonstration of how the application of AI-based methods can lead to healthcare benefits. It also highlights the importance of strong collaboration between leading organisations, as the development of these algorithms was only possible due the EpiCov data sharing initiative pioneered by Cambridge 探花直播 Hospitals.聽</p> <p>鈥淗undreds of millions of full blood count tests are being performed every day worldwide, and this meant that we could apply our AI methods at population scale,鈥 said Gleadall, from the 探花直播 of Cambridge and NHS Blood and Transplant. 鈥淯sually the rich measurement data are discarded after summary results have been reported, but by working with Cambridge 探花直播, Barts Health London, and 探花直播 College London NHS Hospitals we have rescued throughout the pandemic the rich data from 2.8 million full blood count tests.鈥</p> <p> 探花直播Sentinel Forecasting System is the other second-prize winner, and will explore the emergence of new infectious diseases in West Africa, beginning with Lassa fever. 探花直播system will combine data from ecology, social science, genomics and epidemiology to provide real-time disease risk for haemorrhagic fevers, such as Lassa and Ebola.</p> <p>Lassa is a virus usually passed to humans through exposure to food or household items contaminated by infected rats. It is endemic in West African countries including Benin, Ghana, Guinea, Liberia, Mali, Sierra Leone, Togo and Nigeria.</p> <p>Around 80% of people who become infected with Lassa virus have no symptoms, and the overall case-fatality rate is 1%. 1 in 5 infections can result in severe disease affecting the liver, spleen and kidneys.</p> <p> 探花直播UCL team will partner with the African Centre of Excellence for Genomics of Infectious Diseases in Nigeria, Nigeria Centre for Disease Control, Zoological Society of London, London School of Hygiene and Tropical Medicine, Microsoft, and Cambridge鈥檚 Laboratory of Viral Zoonotics (LVZ) to produce the system.</p> <p>鈥淭his Trinity Challenge project brings new multidisciplinary technologies together to anticipate climatic, human, animal population, agricultural impacts on the likelihood of spill overs of infections from animals to humans,鈥 said Professor Jonathan Heeney, who leads LVZ at Cambridge鈥檚 Department of Veterinary Medicine.</p> <p>Additionally, five 3rd prize winners are each being awarded 拢480,000 (US$ 660,000) in pledged funding.</p> <p>Dame Sally Davies said: 鈥淚t was crystal clear at the beginning of this pandemic that the world had a lack of data, a lack of access to data, and a lack of interoperability of data, presenting a challenge.

Fast and accurate diagnosis of patients in order to limit disease spread, together with the rapid determination of whether a patient is likely to recover, require intensive care unit (ICU) admission, or intensive ventilation, is key to allocating resources and to improving patient outcomes.</p> <p>鈥淎I offers huge potential to support agile clinical decision making, ensuring patients receive the most appropriate support and leading to better patient outcomes,鈥 said Sala, who is based at the Department of Radiology.</p> <p>Recent <a href="https://covid19ai.maths.cam.ac.uk/news-results">studies</a> have suggested that using AI could have a meaningful impact on the management of patients with COVID-19. AI tools such as deep learning can offer automated image analysis and integration with clinical data to help clinicians make more informed decisions for treatment.</p> <p>However, good quality data and computing power are required to train and optimise predictive AI models and data availability is a major bottleneck when developing new systems. Coupled with this, the lack of standardisation of datasets makes it challenging to reuse existing AI tools in a different country than the one that it was trained for. Most current AI tools have been developed on small, locally collected datasets. Data that is being collected in hospitals all over the world varies in what is being collected and how the data is processed. Therefore, an effort for developing a widely applicable tool for COVID-19 hospital support must be open source so it can be adapted to different environments; be based on a serious data sharing and data curation, data cleaning and standardisation effort; and be developed with mathematical, statistical and engineering expertise to develop robust and translatable tools.</p> <p>To address these challenges, the team from the Cambridge Centre for Mathematical Imaging in Healthcare (CMIH) is developing a flexible, open-source AI tool that could be used by hospitals worldwide. Drawing on their history of global research collaboration and expertise in data governance, the team is gathering datasets from Austria, China, Italy and the UK for their work. Data scientists and clinicians are working in close collaboration, following standard protocols to identify bias during development. 鈥淩igorous mathematical models play a key role in mitigating bias and improving the efficacy of the prediction model as they follow universal rules with mathematical guarantees,鈥 said Sch枚nlieb.</p> <p>Using deep learning approaches along with mathematical and statistical analysis methods, the new tool will be accompanied by a comprehensive algorithmic strategy that will allow fine-tuning for datasets with different characteristics and implementation in different countries. 探花直播team are hoping to launch the AIX-COV-NET tool within the next 12 to 18 months. 探花直播project has recently received funding from the EU-funded Innovative Medicines Initiative and Intel.</p> <p>鈥淥ur team鈥檚 strength is the close dialogue we have between clinicians and data scientists, and the passion we all bring for advancing AI solutions for COVID-19,鈥 said Sch枚nlieb, from Cambridge's Department of Applied Mathematics and Theoretical Physics.</p> <p>鈥淎I offers huge potential to support agile clinical decision making, ensuring patients receive the most appropriate support and leading to better patient outcomes,鈥 said Sala.</p> <p> 探花直播core project team is comprised of data scientists and clinicians from across Cambridge and is led by Professor Carola-Bibiane Sch枚nlieb, Director of the Centre for Mathematical Imaging in Healthcare, and Professor Evis Sala, Professor of Oncological Imaging, 探花直播 of Cambridge &amp; Honorary Consultant Radiologist, Addenbrooke鈥檚 Hospital, Cambridge 探花直播 Hospitals NHS Foundation Trust. 探花直播team is supported by an AI and image analysis team, drawn from subject experts across Cambridge and around the world, a clinical team comprised of colleagues from hospitals in Cambridge, London and Vienna, and a support team based in the Faculty of Mathematics.

Proto-Indo-European (PIE) is the mother tongue 鈥 shared by several hundred contemporary languages, as well as many now extinct, and spoken by people who lived from about 6,000 to 3,500 BC on the steppes to the north of the Caspian Sea.</p> <p>They left no written texts and although historical linguists have, since the 19th century, painstakingly reconstructed the language from daughter languages, the question of how it actually sounded was assumed to be permanently out of reach.</p> <p>Now, researchers at the Universities of Cambridge and Oxford have developed a sound-based method to move back through the family tree of languages that stem from PIE. They can simulate how certain words would have sounded when they were spoken 8,000 years ago.</p> <p>Remarkably, at the heart of the technology is the statistics of shape.</p> <p>鈥淪ounds have shape,鈥 explains Professor John Aston, from Cambridge鈥檚 Statistical Laboratory. 鈥淎s a word is uttered it vibrates air, and the shape of this soundwave can be measured and turned into a series of numbers. Once we have these stats, and the stats of another spoken word, we can start asking how similar they are and what it would take to shift from one to another.鈥澛</p> <p>A word said in a certain language will have a different shape to the same word in another language, or an earlier language. 探花直播researchers can shift from one shape to another through a series of small changes in the statistics. 鈥淚t鈥檚 more than an averaging process, it鈥檚 a continuum from one sound to the other,鈥 adds Aston, who is funded by the Engineering and Physical Sciences Research Council (EPSRC). 鈥淎t each stage, we can turn the shape back into sound to hear how the word has changed.鈥</p> <p>Rather than reconstructing written forms of ancient words, the researchers triangulate backwards from contemporary and archival audio recordings to regenerate audible spoken forms from earlier points in the evolutionary tree. Using a relatively new field of shape-based mathematics, the researchers take the soundwave and visualise it as a spectrogram 鈥 basically an undulating three-dimensional surface that represents the shape of that sound 鈥 and then reshape the spectrogram along a trajectory 鈥榮ignposted鈥 by known sounds.</p> <p>While Aston leads the team of statistician 鈥榮hape-shifters鈥 in Cambridge, the acoustic-phonetic and linguistic expertise is provided by Professor John Coleman鈥檚 group in Oxford.</p> <p> 探花直播researchers are working on the words for numbers as these have the same meaning in any language. 探花直播longest path of development simulated so far goes backwards 8,000 years from <a href="http://www.phon.ox.ac.uk/jcoleman/one-from-oins.wav">English <em>one</em> to its PIE ancestor <em>oinos</em></a>, and likewise for other numerals. They have also 鈥榞one forwards鈥 from the PIE <em>penkwe</em> to the modern Greek <em>pente</em>, modern Welsh <em>pimp</em> and modern English<em>five</em>, as well as simulating change from Modern English to Anglo-Saxon (or vice versa), and from Modern Romance languages back to Latin.</p> <p><em>(Other audio demonstrations are available <a href="http://www.phon.ox.ac.uk/jcoleman/ancient-sounds-audio.html">here</a>)</em></p> <p>鈥淲e鈥檝e explicitly focused on reproducing sound changes and etymologies that the established analyses already suggest, rather than seeking to overturn them,鈥 says Coleman, whose research was funded by the Arts and Humanities Research Council.</p> <p>They have discovered words that appear to correctly 鈥榝all out鈥 of the continuum. 鈥淚t鈥檚 pleasing, not because it overturns the received wisdom, but because it encourages us that we are getting something right, some of the time at least. And along the way there have also been a few surprises!鈥 探花直播method sometimes follows paths that do not seem to be etymologically correct, demonstrating that the method is scientifically testable and pointing to areas in which refinements are needed.</p> <p>Remarkably, because the statistics describe the sound of an individual saying the word, the researchers are able to keep the characteristics of pitch and delivery the same. They can effectively turn the word spoken by someone in one language into what it would sound like if they were speaking fluently in another.</p> <p><img alt="" src="/sites/www.cam.ac.uk/files/inner-images/160630_horizontal_language_figure.jpg" style="width: 100%;" /></p> <p>They can also extrapolate into the future, although with caveats, as Coleman describes: 鈥淚f you just extrapolate linearly, you鈥檒l reach a point at which the sound change hits the limit of what is a humanly reasonable sound. This has happened in some languages in the past with certain vowel sounds. But if you asked me what English will sound like in 300 years, my educated guess is that it will be hardly any different from today!鈥</p> <p>For the team, the excitement of the research includes unearthing some gems of archival recordings of various languages that had been given up for dead, including an Old Prussian word last spoken by people in the early 1700s but 鈥榖orrowed鈥 into Low Prussian and discovered in a German audio archive.</p> <p>Their work has applications in automatic translation and film dubbing, as well as medical imaging (see panel), but the principal aim is for the technology to be used alongside traditional methods used by historical linguists to understand the process of language change over thousands of years.</p> <p>鈥淔rom my point of view, it鈥檚 amazing that we can turn exciting yet highly abstract statistical theory into something that really helps explain the roots of modern language,鈥 says Aston.</p> <p>鈥淣ow that we鈥檝e developed many of the necessary technical methods for realising the extraordinary ambition of hearing ancient sounds once more,鈥 adds Coleman, 鈥渢hese early successes are opening up a wide range of new questions, one of the central being how far back in time can we really go?鈥</p> <p><em>Audio demonstrations are available here: <a href="http://www.phon.ox.ac.uk/jcoleman/ancient-sounds-audio.html">www.phon.ox.ac.uk/jcoleman/ancient-sounds-audio.html</a></em></p> <p><em>Inset image: Spectrograms showing how the shape of the sound of a word in one language can be morphed into the sound of the same word in another language; credit: John Aston.</em></p> </div></div></div><div class="field field-name-field-content-summary field-type-text-with-summary field-label-hidden"><div class="field-items"><div class="field-item even"><p><p> 探花直播sounds of languages that died thousands of years ago have been brought to life again through technology that uses statistics in a revolutionary new way.</p> </p></div></div></div><div class="field field-name-field-content-quote field-type-text-long field-label-hidden"><div class="field-items"><div class="field-item even">As a word is uttered it vibrates air, and the shape of this soundwave can be measured and turned into a series of numbers</div></div></div><div class="field field-name-field-content-quote-name field-type-text field-label-hidden"><div class="field-items"><div class="field-item even">John Aston</div></div></div><div class="field field-name-field-image-credit field-type-link-field field-label-hidden"><div class="field-items"><div class="field-item even"><a href="/" target="_blank">John Aston</a></div></div></div><div class="field field-name-field-image-desctiprion field-type-text field-label-hidden"><div class="field-items"><div class="field-item even">Spectrogram showing the shape of the sound of a word</div></div></div><div class="field field-name-field-panel-title field-type-text field-label-hidden"><div class="field-items"><div class="field-item even">Medical imaging reshaped</div></div></div><div class="field field-name-field-panel-body field-type-text-long field-label-hidden"><div class="field-items"><div class="field-item even"><p><strong> 探花直播statistics of shape are not just being used to show how different languages relate to each 鈥 they are also being used to improve the analysis of medical images.</strong></p> <p>Just as soundwaves have a shape that can be analysed using statistics, so do the patterns of neurons interacting with each other or the dimensions of the surface of a tumour.

An image aims to depict reality to us, but also invokes our imagination. It speaks more than a thousand words. We live in a world saturated with images and images allow us to see this world 鈥 from brain cells to distant galaxies 鈥 as never before. Advanced imaging techniques enable us to ask new research questions, break down disciplinary boundaries and extend our knowledge across an immense variety of fields.聽</p>&#13; <p>Scientists have always used images of various kinds 鈥 drawings, pictures, photographs and videos, to name a few 鈥 to make discoveries, describe processes in nature, catalogue and achieve specimens, and illustrate observations and ideas. In scientific discoveries, images are often the scientific finding itself.</p>&#13; <p>A work of art, an image in itself, can be analysed and its making can be understood with the help of advanced scientific imaging techniques. New images are created by this analysis, and the worlds of arts and science are becoming increasingly overlapping.聽</p>&#13; <p>Scientific imaging has never been as exciting as it is now, with new technologies emerging all the time. 探花直播resolution limit in light microscopy, which had seemed unbreakable, is now less than 100 nanometres. These advances in super-resolved fluorescence microscopy were recognised in聽 2014 by the awarding of the Nobel Prize in Chemistry to Eric Betzig and W. E. Moerner in the USA and Stefan Hell in Germany.</p>&#13; <p>Cambridge is home to a wealth of research which includes developing tools for acquisition, visualisation, automated processing and analysis of images. In January 2014, a group was formed to connect, present, discuss and advance research on or with images. <a href="https://www.images.group.cam.ac.uk/">IMAGES </a>brings together leading academics from across the disciplines, as well as international experts and research-led industries that work on pioneering imaging technologies and analytical algorithms.</p>&#13; <p> 探花直播complex process, from acquiring images, to their interpretation and problem-solving applications, requires multi-expertise partnerships. Different problems and image applications inform similar methodologies and interpretative strategies. Cross-disciplinary collaboration is needed to analyse the image information not explicit in machine-generated data.</p>&#13; <p>Mathematicians, physicists, chemists and biologists work together to develop new instruments, chemical dyes and model systems to interrogate biological questions with more precision and at greater resolution.</p>&#13; <p>At CRUK Cambridge Institute and the Department of Applied Mathematics and Theoretical Physics, microscopists and mathematicians are developing new ways of tracking cells and analysing the effect of cancer drugs in tissues and whole organisms.</p>&#13; <p>At the Cambridge Biomedical Campus, clinicians use magnetic resonance, positron emission tomography, and acoustic imaging as tools for looking into our internal organs. 探花直播challenge here is to produce a high quality description of patients and their ailments from data that is necessarily limited by the capability of scanners and the need to minimise exposure to harmful radiation.</p>&#13; <p>Mathematicians and engineers create automated image-processing and analysis algorithms that extract meaningful, essential information from often large-scale, high-dimensional and imperfect image data.</p>&#13; <p> 探花直播importance of reliable image analysis extends to astronomy, the arts, seismology, surveillance and security. Image de-noising and image restoration algorithms are also essential pieces of any further image analysis pipeline such as object segmentation and tracking, pattern recognition, in fact any quantitative and qualitative analysis of image content.</p>&#13; <p>At the Fitzwilliam Museum and the Hamilton Kerr Institute, spectroscopy methods underpin the non-invasive analyses of artists鈥 materials and techniques, informing the conservation and cross-disciplinary interpretation of paintings, illuminated manuscripts and Egyptian papyri. 探花直播research unites imaging scientists, chemists, physicists, mathematicians, biologists, conservators, artists and historians. Thanks to cutting-edge imaging techniques, we can now see art works as never before, uncovering centuries-long secrets of their production and ensuring their preservation into the future.</p>&#13; <p> 探花直播IMAGES group aims to stimulate new inquiries and focused dialogues between these many disciplines across the sciences, arts and humanities by providing them with a platform for communication. As collaborations across the 探花直播 show, art and science are not disparate, but complementary ways of seeing the world.
