Improving contact-tracing apps in the COVID-19 era
Improving contact-tracing apps in the COVID-19 era
An international collaboration with EPFL has developed a method to improve the performance of COVID-19 contact-tracing apps by taking into account a user's recent contacts, risk levels and shared information about tests and symptoms. Contact-tracing apps like SwissCovid have enormous potential to mitigate the spread of the COVID-19 pandemic.

From chemical Graphs To Structures
From chemical Graphs To Structures
Three-dimensional (3D) configurations of atoms dictate all materials properties. Quantitative predictions of accurate equilibrium structures, 3D coordinates of all atoms, from a chemical graph, a representation of the structural formula, is a challenging and computationally expensive task which is at the beginning of practically every computational chemistry workflow.

Four cryptographic vulnerabilities in Telegram
Four cryptographic vulnerabilities in Telegram
An international research team of cryptographers completed a detailed security analysis of the popular Telegram messaging platform identifying several weaknesses in its protocol that demonstrate the product falls short of some essential data security guarantees. Working with only open-source code and without "attacking" any of Telegram's running systems, a small team of international researchers completed a detailed analysis of the company's encryption services.

Zeitabhängige Berechnung eines Bose-Einstein-Kondensats
The term Bose-Einstein condensate describes a state of matter in which atoms or elementary particles combine into a single quantum mechanical object during extreme cooling. Science does not yet fully understand exactly how these macroscopic states - beyond the confines of traditional physics - develop from a thermal atomic cloud in just a few milliseconds and when statistical equilibrium is reached, according to Georg Wolschin.

Mathematics to improve macular degeneration treatment
Researchers from the Universidad Carlos III de Madrid (UC3M) have created a mathematical model and simulated numerically the progression of age-related macular degeneration, one of the main causes of blindness. This model can be used to better understand how this disease appears and assess the most effective treatments.

Modeling the friction between pages in a book
Modeling the friction between pages in a book
Engineers at EPFL and École Polytechnique in France analyzed the friction between pages in a book and the mechanical force needed to bend them. Drawing on their experiments, they developed a new theoretical model for predicting the elasto-frictional behavior of stacked layers. It all started with a shaky washing machine.

Digital school books help low-achieving pupils
Digital school books help low-achieving pupils
Study on use of tablets in mathematics Low-achieving pupils benefit more in mathematics lessons from learning materials on tablet PCs than high-achieving children. They are obviously helped by individualized learning paths, immediate feedback and the hands-on processing of interactive content. This conclusion was reached in a study conducted by the Technical University of Munich (TUM) with sixth-grade students.

Mathematicians find core mechanism to calculate tipping points Climate change, a pandemic or the coordinated activity of neurons in the brain: In all of these examples, a transition takes place at a certain point from the base state to a new state. Researchers at the Technical University of Munich (TUM) have discovered a universal mathematical structure at these so-called tipping points.

USI develops innovative system for better credit card fraud detection
USI develops innovative system for better credit card fraud detection
The use of credit cards and other cashless or digital payment methods has become the norm for consumers all over the globe, and the strong surge of online buying during the pandemic has further boosted this decade-long trend. However, behind the convenience of 'click and pay' there are also risks, such as fraud and related losses, which are mostly borne by the card companies.

Theory and experiments to understand a contact between two filaments
Theory and experiments to understand a contact between two filaments
Mechanical engineers and mathematicians at EPFL have joined forces to gain a better understanding of the geometry and mechanics of two filaments in contact - as in the cases of knots and woven fabrics. Pedro Reis, head of EPFL's Flexible Structures Laboratory, and John Maddocks, head of EPFL's Laboratory for Computation and Visualization in Mathematics and Mechanics, have something in common: a fascination with ropes and knots.

Math Professor Makes Breakthrough in Ramsey Numbers
How many people would you need at a party to guarantee that at least three individuals know each other, or that at least three do not know each other? Working this out with pen and paper may take a while, but many mathematicians will readily tell you the answer is six. This party scenario, also called the "friends and strangers" theorem, is based on a concept known as Ramsey numbers, named after early 20th-century British Mathematician Frank Ramsey.

U-M physics undergraduate proposes solution to quantum field theory problem
When physicists need to understand the quantum mechanics that describe how atomic clocks work, how your magnet sticks to your refrigerator or how particles flow through a superconductor, they use quantum field theories. When they work through problems in quantum field theories, they do so in "imaginary” time, then map those simulations into real quantities.

COVID-19 Screening: A New Model for Assessing the Efficiency of Group Testing
COVID-19 Screening: A New Model for Assessing the Efficiency of Group Testing
How best to evaluate the performance of a group testing strategy for the SARS-CoV-2 virus, which involves pooling samples from multiple individuals in order to conduct a single RT-PCR test on the whole group? To do precisely that, scientists from the CNRS, l'université Grenoble Alpes, and l'université Sorbonne Paris Nord 1 have developed a model that evaluates the efficiency of such tests.

Solving a 100 year-old maths puzzle
For 100 years mathematicians have been trying to solve the question of whether it is possible to fit all four points of a rectangle into any given closed curve shape. Or, more bluntly, can you fit a square peg into a round hole? Research so far had found that it was only possible to fit the proverbial square peg into a round hole if the peg in question was of certain proportions, until now...

’Multiplying’ light could be key to ultra-powerful optical computers
New type of optical computing could solve highly complex problems that are out of reach for even the most powerful supercomputers. An important class of challenging computational problems, with applications in graph theory, neural networks, artificial intelligence and error-correcting codes can be solved by multiplying light signals, according to researchers from the University of Cambridge and Skolkovo Institute of Science and Technology in Russia.

A NEAT reduction of complex neuronal models accelerates brain research
Unlike their simple counterparts in artificial intelligence (AI) applications, neurons in the brain use dendrites - their intricate tree-like branches - to find relevant chunks of information. Now, neuroscientists from the University of Bern have discovered a new computational method to make complex dendrite models much simpler.
