The surgeon, Dr. Erney Mattsson, saw an unsolved problem with the bandage he used in his practice; the mathematician, professor Torbjörn Lundh, together with PhD student Jonatan Vasilis, solved the problem with a mathematical formula. The mathematical formula was handed over to Josefin Damm, the textile developer, who interpreted it into a textile. <div><br /></div> <div> The knitted textile construction that makes Lundatex® medical bandage has very specific properties. Further, visual guides on the bandage control the overlap and the force used during application. This results in a bandage with a mathematical formula built into a textile material.

In this way, a more comprehensive view of how cells accumulate damages and age has emerged</b></p><p>​As the world population gets increasingly older, we need to understand how to avoid age-related diseases. One important part of this is to understand ageing on a cellular level. Research on cells is usually done through experiments in a laboratory, and in that way a lot of isolated processes in the cells have been analysed. But the cell ageing is also characterised by the interactions of these processes, and the interactive and multi-scale dimensions are not always possible to study in a laboratory environment. To get a broader insight on how cells age, this project has been using mathematics in the form of different models for different cellular processes closely connected to ageing.</p> <h2>Mathematical models to describe cellular processes</h2> <p>The three chosen processes are the signalling system, which is able to sense changes in the cellular environment; the metabolism, which converts food into energy; and damage accumulation, which defines ageing in Barbara’s project. Depending on the available details of the biology, these networks have been translated into Boolean models, optimisation models (so-called flux balance analysis), and ordinary differential equations.</p> <p><img class="chalmersPosition-FloatRight" src="/SiteCollectionImages/Institutioner/MV/Nyheter/BarbaraSchnitzer250x300.jpg" alt="" style="margin:5px" />– All models have been combined to get an understanding of how the processes interact, since this interaction is important when the cell loses its function. The results are different predictions and suggestions on how these interactions work. The next step would be for the biologists to take, through verification experiments in the laboratory. The results can also be further built upon through adding more cellular processes and defining the connections between them.</p> <h2>Erasmus exchange led to Gothenburg</h2> <p>Barbara’s Bachelor degree, which she took in Germany, was neither in mathematics nor biology but in physics. She went to the University of Gothenburg in a six-month Erasmus exchange and there found the Master programme Complex Adaptive Systems which appealed to her. The programme included courses in computational biology, and when doing her Master’s thesis the PhD position that Barbara has had turned up. For the last two years she has worked closely to PhD Linnea Österberg, an experimentalist and biologist working in the same project group who defended her thesis on April 29. From the beginning they had separate projects, but the cooperation evolved naturally and they have had the benefit of going through the PhD work together.</p> <p>– A highlight during these years was when we gave a popular science talk called “A mathematician and a biologist walk into a bar” (<a href="https://urplay.se/program/225281-ur-samtiden-vetenskapsfestivalen-2021-en-matematiker-och-en-biolog-gar-in-i-en-bar">En matematiker och en biolog går in i en bar</a>, on UR Play) during the International Science Festival Gothenburg. Since it was in the year of 2021 it was digital, sent live from a studio, which was an interesting experience even if I was nervous. I think it is important for scientists to be able to explain what we do.</p> <p>Barbara has liked living in Gothenburg and finds the PhD conditions in Sweden good, since it is like a normal job with a secure employment and fixed salary. In the beginning she lived with a Swedish girl and chose to speak Swedish all the time, which together with some courses gave her a good knowledge of the language. The research language is however always English, so it is easier to talk about work in English. Barbara has also taught courses, mostly basic mathematics courses but also a master’s course. She found it hard in the beginning but kind of grew into it, and now sees it as a nice experience. Now, she will start looking for a job in industry.</p> <p><em>Barbara Schnitzer will defend her PhD thesis “</em><a href="https://gupea.ub.gu.se/handle/2077/70867?locale-attribute=en"><em>Mathematical Modelling of Cellular Ageing: A Multi-Scale Perspective</em></a><em>” on May 13 at 10.15 in lecture hall Pascal, Hörsalsvägen 1, and via Zoom.

However, most real numbers cannot be expressed in this manner – they are irrational. The best-known irrational numbers include π and the square root of two, √2. How these irrational numbers should be best approximated using rational numbers has, in its simplest form, been well understood for more than a century. The field of diophantine approximation, which this project is about, examines how well an approximation can be performed using rational numbers for a given real number.<br /><br /> One way of approaching the question is to calculate the number of rational numbers that provide good approximations to a given real number and which have denominators below a specified high limit. It has been known since the 1960s that, for almost all real numbers, their quantity grows towards infinity at an almost exactly logarithmic rate with the given limit for the denominator. Deviations from this rate fulfil a specific form of the central limit theorem, i.e. a normal distribution, as recently proven by Michael Björklund and Alexander Gorodnik. <br /><br /> The purpose of the project is, in the next step, to move beyond the normal distribution. The basis for understanding deviations from the normal distribution is the already well-known analysis of the sums of independent random variables and the central limit theorem. In the case being studied, the random variables are only partially independent, but the analogy may bear fruit and lead to better estimations that those now known. <br /></div> <h2 class="chalmersElement-H2">The shape of the universe</h2> <img src="/SiteCollectionImages/Institutioner/MV/Nyheter/KAW%202021/Mingchen-Xia-Chalmers.gif" class="chalmersPosition-FloatRight" alt="Mingchen Xiao" style="margin:5px;width:225px;height:192px" /> <div><a href="/en/staff/Pages/xiam.aspx">Mingchen Xia, PhD student</a> in the Division for Algebra and Geometry, Department of Mathematical Sciences, receives funding for a postdoctoral position with Professor Sébastien Boucksom at the École Polytechnique, Palaiseau, France. </div> <div><br /></div> <div>Time and space shape our universe. The theory of how they are connected was developed in the eighteenth century by Isaac Newton. However, in his Principia Matematica, time and three-dimensional space are independent. They were first linked in a shared spacetime almost 200 years later, when James Clerk Maxwell realised that the speed of light in a vacuum was constant, regardless of who measured it. This was only possible if space and time were regarded as a unity – a spacetime. </div> <div><br /></div> <div> Spacetime received its precise mathematical description in Albert Einstein’s masterpiece – the general theory of relativity, which was published just over a century ago. The theory describes the shape of the universe as a four-dimensional surface. Its shape is determined by the matter content of space – the more matter, the more curved the surface. But what is the shape of the universe if all matter is removed, how can a vacuum be described? If there is nothing at all, is the universe then entirely flat? The answer was astounding – it turns out that the theory of relativity actually permits many non-flat vacua. </div> <div><br /></div> <div> In the theory of relativity, the exact relationship between matter and the shape of the cosmos is given a set of differential equations, Einstein’s field equations. These are notoriously difficult to solve and several different approaches have been developed over the past century to obtain direct solutions for spacetime. One of the most recent is pluripotential theory, an area within complex mathematical analysis. The plan is to use these methods to help explore the intricate geometry of the vacuum. </div> <h2 class="chalmersElement-H2">About the Knut and Alice Wallenberg Foundation program for mathematics</h2> <div><span style="background-color:initial">Over the years 2014–2029, the program will provide SEK 650 million to allow Swedish researchers to receive international postdoctoral positions, as well as the international recruitment of visiting professors and of foreign researchers to postdoctoral positions at Swedish universities.

Now, a new article in Nature Communications, written by researchers from Chalmers University of Technology, Sweden, and MIT, USA, presents results that cast new light on important challenges in understanding quantum gravity.</b></p>A grand challenge in modern theoretical physics is to find a ‘unified theory’ that can describe all the laws of nature within a single framework – connecting Einstein's general theory of relativity, which describes the universe on a large scale, and quantum mechanics, which describes our world at the atomic level. Such a theory of ‘quantum gravity’ would include both a macroscopic and microscopic description of nature.<div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/MV/Nyheter/Nature%202022/Daniel-Persson.gif" class="chalmersPosition-FloatRight" alt="Daniel Persson" style="margin:5px;width:200px;height:300px" /> “We strive to understand the laws of nature and the language in which these are written is mathematics. When we seek answers to questions in physics, we are often led to new discoveries in mathematics too. This interaction is particularly prominent in the search for quantum gravity – where it is extremely difficult to perform experiments,” explains Daniel Persson, Professor at the Department of Mathematical Sciences at Chalmers university of technology.</div> <div><br /></div> <div> An example of a phenomenon that requires this type of unified description is black holes. A black hole forms when a sufficiently heavy star expands and collapses under its own gravitational force, so that all its mass is concentrated in an extremely small volume. The quantum mechanical description of black holes is still in its infancy but involves spectacular advanced mathematics.</div> <div><br /></div> <h2 class="chalmersElement-H2"> A simplified model for quantum gravity</h2> <div><img src="/SiteCollectionImages/Institutioner/MV/Nyheter/Nature%202022/Robert-Berman.gif" alt="Robert Berman" class="chalmersPosition-FloatLeft" style="margin:5px;width:200px;height:265px" />“The challenge is to describe how gravity arises as an ‘emergent’ phenomenon. Just as everyday phenomena – such as the flow of a liquid – emerge from the chaotic movements of individual droplets, we want to describe how gravity emerges from quantum mechanical system at the microscopic level,” says Robert Berman, Professor at the Department of Mathematical Sciences at Chalmers University of Technology.</div> <div><br /></div> <div> In an article recently published in the journal Nature Communications, Daniel Persson and Robert Berman, together with Tristan Collins of MIT in the USA, showed how gravity emerges from a special quantum mechanical system, in a simplified model for quantum gravity called the ‘holographic principle’.</div> <div><br /></div> <div>“Using techniques from the mathematics that I have researched before, we managed to formulate an explanation for how gravity emerges by the holographic principle, in a more precise way than has previously been done,” explains Robert Berman.</div> <h2 class="chalmersElement-H2"> Ripples of dark energy</h2> <div> The new article may also offer new insight into mysterious dark energy. In Einstein's general theory of relativity, gravity is described as a geometric phenomenon. Just as a newly made bed curves under a person's weight, heavy objects can bend the geometric shape of the universe. But according to Einstein's theory, even the empty space – the ‘vacuum state’ of the universe – has a rich geometric structure. If you could zoom in and look at this vacuum on a microscopic level, you would see quantum mechanical fluctuations or ripples, known as dark energy. It is this mysterious form of energy that, from a larger perspective, is responsible for the accelerated expansion of the universe.</div> <div><br /></div> <div>This new work may lead to new insights into how and why these microscopic quantum mechanical ripples arise, as well as the relationship between Einstein's theory of gravity and quantum mechanics, something that has eluded scientists for decades.</div> <div><br /></div> <div>“These results open up the possibility to test other aspects of the holographic principle such as the microscopic description of black holes. We also hope to be able to use these new connections in the future to break new ground in mathematics,” says Daniel Persson.</div> <div><br /></div> <div> The scientific article, <a href="https://doi.org/10.1038/s41467-021-27951-9">Emergent Sasaki-Einstein geometry and AdS/CFT</a>, is published in Nature Communications and is written by Robert Berman, Tristan Collins and Daniel Persson at Chalmers University of Technology, Sweden, and Massachusetts Institute of Technology, USA. </div> <h3 class="chalmersElement-H3">For more information, contact:</h3> <div> Daniel Persson, Professor, Department of Mathematical Sciences, Chalmers university of Technology and University of Gothenburg <br /><a href="mailto:daniel.persson@chalmers.se">daniel.persson@chalmers.se</a> <br />+46 31 772 3174</div> <div><br /></div> <div>Robert Berman, Professor, Department of Mathematical Sciences, Chalmers university of Technology and University of Gothenburg</div> <div><a href="mailto:robertb@chalmers.se">robert.berman@chalmers.se</a> </div> <div>+46 31 772 3553   </div> <div><br /></div> <div>Text: Joshua Worth</div> <div>Photo: Anna Wallin (Daniel Persson) and Rakel Berman (Robert Berman)</div> ​​​Mon, 07 Mar 2022 14:00:00 +0100https://www.chalmers.se/en/departments/math/news/Pages/Goran-Gustafsson-Prize-to-David-Witt-Nystrom.aspxhttps://www.chalmers.se/en/departments/math/news/Pages/Goran-Gustafsson-Prize-to-David-Witt-Nystrom.aspxGöran Gustafsson Prize to David Witt Nyström<p><b>​David Witt Nyström, Associate Professor at the University of Gothenburg, receives the mathematics prize “for his deep and innovative work in complex analysis with important applications in complex and algebraic geometry”.</b></p>​<p><img width="250" height="297" class="chalmersPosition-FloatRight" alt="David Witt Nyström" src="/SiteCollectionImages/Institutioner/MV/Nyheter/DavidWittNystrom_Foto_Privat250.jpg" style="margin:5px" />In algebraic geometry, the study objects are curves, surfaces and object of higher dimensions (so-called manifolds) that have in common that they are defined with the help of polynomials. One example is the circle, which can be described as the points in the plane where the polynomial x^2+y^2-1 is zero. Although the circle is easy to understand, manifolds of this kind can be extremely intricate, especially in higher dimensions.</p> <p>The specific research area for David Witt Nyström, Kähler geometry, focuses on how a manifold’s small-scale form, its curvature, is related to its large-scale form, its topology. In addition to algebraic methods this demands advanced tools from complex analysis.</p> <p>David Witt Nyström has, among other things, proved a conjecture (proposition) well-known in the area. It describes how, in a specific context, global topological data are determined by local curvature properties.</p> <p>Another major track in his research is the Hele-Shaw flow, which describes how a viscous liquid moves in a thin layer. There, an unexpected connection to Kähler geometry led to a much discussed counterexample to a well-known conjecture.</p> <p>– I am incredibly happy and honoured to have been awarded the Göran Gustafsson Prize, and it will clearly be of great importance for my further research, he says.</p> <p><strong>Text and photo</strong>: from the page of the <a href="https://www.kva.se/sv/pressrum/pressmeddelanden/goran-gustafssonprisen-till-forskning-om-cancertumorer-och-kvantmaterial">Royal Swedish Academy of Sciences, read more about the prize and the prize winners in other subjects (in Swedish) &gt;&gt;</a></p>Fri, 04 Mar 2022 15:30:00 +0100https://www.chalmers.se/en/areas-of-advance/ict/news/Pages/the-allwise-alvis.aspxhttps://www.chalmers.se/en/areas-of-advance/ict/news/Pages/the-allwise-alvis.aspx​Time to inaugurate all-wise computer resource<p><b>​Alvis is an old Nordic name meaning &quot;all-wise&quot;.

As such, these novel complex formulations are mainly used in the field of oncology.</div> <div><br /></div> <div>To facilitate the design and development of such nanoparticle formulations, physiologically based biopharmaceutics models (PBBM) could be used to simulate the drug performance in vivo. While such models have been used for other formulations, a PBBM including nanoparticle transport would be a novel development.

The project would have a major impact on the development of novel nanosized formulations, in particular for tumour treatment. It would reduce the extent of animal testing required and enable exploratory research of innovative solutions that cannot be studied in vivo.<br />The main deliverable is a PBBM of the body, including mechanistic models of nanoparticle transport, drug release from nanoparticles and a solid tumour model, together with suitable numerical tools.<br /></div> <div><br /> </div> <div><img src="/SiteCollectionImages/Institutioner/MV/Profilbilder/tobiasgeback.jpg" class="chalmersPosition-FloatRight" alt="Tobias Gebäck" style="margin:5px" />– The opportunity to work on site at AstraZeneca will give me a deeper insight into the use of mathematical modeling in the pharmaceutical industry today, and what challenges they face.

An analysis covering 20 years of scientific publications related to chemical pollution show that the majority of studies have focused on as few as 65 individual chemicals. Meanwhile, the number of chemicals used by society is rapidly increasing. </b></p><div>A team of researchers has analysed 130,000 scientific articles published within the field of environmental pollution research during the last two decades. <br /></div> <div><br /></div> <div>“We found that the scientific literature was dominated by a surprisingly small group of chemicals while there is very little knowledge about the many of the other chemicals used by society. It is apparent that the research community needs to catch up with current chemical uses and innovations”, says Erik Kristiansson, professor at the Department of Mathematical Sciences and the main author of the study. <br /></div> <h2 class="chalmersElement-H2">Lack of information </h2> <div>The analysis of the scientific literature showed that, in the last 20 years, studies have generally focused on a fraction of the total number of chemicals used by society. Of the approximately 20,000 chemicals included in the study, as few as 65 were mentioned regularly. </div> <div><br /></div> <div>“Scientific knowledge is an important component in environmental regulation. Today, there is a lack of information on many of the chemicals used by society, including their toxicity and their abundance in the environment. This negatively impacts our ability to assess risks and to take informed regulatory decisions. Both decision-makers and researchers, but also research funding organizations, need to be aware of this problem”, says Kristiansson. </div> <div><br /></div> <div>Despite new chemicals being developed at a rapid pace, there is a lack of information for many of them. <br /></div> <div><br /></div> <div>“Since chemicals are used in everything from medicines and pesticides to everyday consumer items such as food, clothing and toys, we have to know that they are not toxic to us humans, or to the environment,” says Thomas Backhaus, director of FRAM and professor in environmental sciences. </div> <div><br /></div> <div>“Furthermore, exposure to chemicals has been linked to a range of health problems, such as cancer, obesity and infertility and also to environmental damages in aquatic ecosystems and on land”, continues Backhaus. </div> <div><h2 class="chalmersElement-H2">Change of research focus </h2></div> <div>The scientific knowledge for some chemicals consists mainly of research performed by companies which is then published in scientific journals. </div> <div><br /></div> <div>“The research focus has changed dramatically over the last 20 years.

The award is a recognition of excellence in promoting gender equality and diversity at Chalmers.</b></p><p>​<img class="chalmersPosition-FloatRight" alt="Julie Rowlett" src="/SiteCollectionImages/Institutioner/MV/Nyheter/JulieRowlettNyhet.jpg" style="margin:5px" /><a href="/en/departments/e2/network/wise/Pages/default.aspx">Wise, Workforce for Inclusive SciencE</a>, celebrates their 10-year anniversary by instituting the Wise Equality Award to reward good efforts. Wise is a supportive network aiming to promote a gender inclusive academia with the vision to foster equal opportunities for any gender to qualify for positions and to make a career in academia. They arrange among other things seminars, workshops and a mentorship programme. The network was initiated by persons at the Department of Electrical Engineering, which is host for the network, and open to both women and men.</p> <p>The nominees for the award should be either students or employees at Chalmers or joint departments at University of Gothenburg. The criteria were among other things that the nominee should be a promoter of inclusiveness and gender equality at the workplace and a role model, demonstrate commitment to an improved and inclusive environment for gender equity on campus, and show commitment to women’s and gender equity issues.</p> <p>Julie Rowlett receives the award for her daily work and to highlight that even small things in everyday life can be very important. The nomination from the students reads in its entirety:</p> <p><em>Julie has inspired many students with her teaching style by being funny, kind and motivational, while transferring knowledge effectively. She broke stereotypes always dressed in pink and talking about her cats, showing that women in maths can be however they want. As director of the engineering mathematics programme, she showed true engagement in her role by demonstrating that she genuinely cares about the students. Through her engagement with the women association for engineering physics and engineering mathematics students Julie has kept on the agenda the importance of considering the students’ situation and of supporting female and nonbinary students. She understands the importance of inspiring through good role models, and she is active in organising events with this aim. For example, she once invited a great female mathematician to speak about the role of women in mathematics. In her research, Julie tries to publish with other female mathematicians as much as possible. </em></p> <p><em>All in all, Julie has already inspired so many students in engineering physics and engineering mathematics and she is always bringing new ideas on how to improve things to the table. Julie deserves this award since she is a role model, shows commitment to gender equity issues and has organised several activities as well as mentored and promoted women.</em></p> <br /><strong>Photo</strong>: Setta AspströmFri, 26 Nov 2021 11:35:00 +0100https://www.chalmers.se/en/departments/math/news/Pages/Funding-Swedish-Research-Council-2021.aspxhttps://www.chalmers.se/en/departments/math/news/Pages/Funding-Swedish-Research-Council-2021.aspxFunding from the Swedish Research Council 2021<p><b>​The following employees at Mathematical sciences have received grants from the Swedish Research Council's call within Natural and Engineering Sciences 2021.</b></p><p>​Dennis Eriksson – Spegelsymmetri i genus ett</p> <p>Eusebio Gardella – Medelbarhet i praktiken</p> <p>Tatiana Shulman – Stabilitet för C*-algebror och grupper</p> <p>Anders Södergren – L-funktioner, zetafunktioner och gitter i hög dimension</p> <p><br /></p> <p><a href="/en/news/Pages/Prestigious-funding-to-researchers-at-Chalmers.aspx">List of funded projects at Chalmers</a></p> <p><br /></p> <p><a href="https://www.gu.se/nyheter/72-miljoner-i-forskningsbidrag-till-naturvetenskap-och-teknik">List of funded projects at University of Gothenburg (in Swedish)​</a></p> <p> </p> <a href="https://www.vr.se/english/applying-for-funding/decisions/2021-08-25-natural-and-engineering-sciences.html"><p>The complete list of grants (in Swedish) and statistics about them</p></a>Fri, 05 Nov 2021 10:20:00 +0100
