When Autocracies Have No Respect for the Nobel Prize BY INA SHAKHRAI As both the fi rst writer and the fi rst woman from Belarus to receive the Nobel Prize in Literature, Svetlana Alexievich became a centre of public attention worldwide. While the fi rst tweets from the Nobel announcement room generated some confusion regarding this unknown writer from an unknown land – with about “10,000 reporters googling Svetlana Alexievich” (Brooks 2015) – the subsequent media coverage of the writer in such publications as The Guardian, The New Yorker, and Der Spiegel sketched out a broad picture of Alexievich’s life, career and main works. Meanwhile, the Belarusian state media remained reluctant to give the award much attention: the upcoming presidential elections and Lukashenka’s visit to Turkmenistan took priority. In a couple of cafes and art spaces in Minsk young people gathered to watch Alexievich’s speech live via the Internet. Independent and alternative websites offered platforms for discussion and the exchange of opinions. Interestingly, the general public was divided over the question of the “Belarusianness” of Alexievich. The identity of the protagonist in Alexievich’s books caused a heated discussion among Russian intellectuals as well. They could hardly accept that Alexievich’s works might epitomize the experience of a genuinely Soviet individual, as they set out to. There was also much speculation on whether Alexievich should be acknowledged as a Russian writer, or whether the West treated her as Belarusian in order to chastise Russia. The events surrounding Alexievich’s Nobel Prize represent a revealing example of the all-encompassing nature of autocratic political systems, as well as how confusing and interwoven national identities can be. -

Schaak DuPont Professor of Materials Chemistry Darrell Velegol Distinguished Professor of Chemical Engineering *Signatures are on file in the Graduate School. iii ABSTRACT Colloidal assemblies of self-powered active particles have become a focus area of research. Ranging from microscopic particle suspensions to nanoscale molecules, these systems transduce chemical energy into mechanical motion across multiple length scales following a variety of mechanisms. Understanding the energy transduction processes and the subsequent nature of particle dynamics offers unprecedented opportunities to explore the physics of small-scale colloidal systems and to harness their behavior in many useful applications. However, over a decade after the initial discovery of autonomous bimetallic nanorods, we continue to struggle to bring such systems into real-world applications. Part of the setback has been the in-depth research into hydrogen peroxide fuel. While the studies have built up the fundamental knowledge necessary for the advancement of the field, we have yet to do the same for other systems that employ alternate fuels. This dissertation aims to fill that void by developing nano- and micromotor and pump systems that does not rely on traditional hydrogen peroxide fuel, uses novel material by taking inspiration in other areas of research, and complete in-depth studies to provide a clear understanding of such systems. -

1 Introduction
1 1 Introduction 1.1 Global Challenges Water, food, and energy security represent major challenges to the stability and continuity of human populations. However, rapid population growth and steadily improving living standards place enormous pressures on already stressed water resource and agricultural systems. Large amounts of energy are consumed to produce clean water and to treat wastewaters prior to their return to the environ- ment, which inevitably leads to a considerable amount of carbon dioxide (CO2) emissions as well as releasing other environmental pollutants. At the global scale, about 2600 km3 of water are withdrawn to supply food- driven irrigation needs every year. Viewed another way, agriculture consumes nearly 70% of total human freshwater withdrawals. This number is to increase to more than 83% by 2050 to meet the growing food demand by the rapidly growing population. In the last 25 years, access to water with potable quality has gone up from 75% to 90% of the world population, and, nevertheless, 884 million people nowadays still lack access to adequate drinking water in many geographical regions [1]. Thus, ensuring a stable and sustainable water, food, and energy supply into the future is a priority for all nations. Adding to an already dreadful situation, water pollution is becoming a major global challenge [2, 3]. From the United Nations World Water Development Report in 2018, it is said that more than 2 billion people lack access to safe drink- ing water and more than double that number lack access to safe sanitation. With a rapidly growing global population, demand for water is expected to increase by nearly one-third by 2050 [4]. -
Multiplicative Differentials
Multiplicative Differentials Nikita Borisov, Monica Chew, Rob Johnson, and David Wagner University of California at Berkeley Abstract. We present a new type of differential that is particularly suited to an- alyzing ciphers that use modular multiplication as a primitive operation. These differentials are partially inspired by the differential used to break Nimbus, and we generalize that result. We use these differentials to break the MultiSwap ci- pher that is part of the Microsoft Digital Rights Management subsystem, to derive a complementation property in the xmx cipher using the recommended modulus, and to mount a weak key attack on the xmx cipher for many other moduli. We also present weak key attacks on several variants of IDEA. We conclude that cipher designers may have placed too much faith in multiplication as a mixing operator, and that it should be combined with at least two other incompatible group opera- ¡ tions. 1 Introduction Modular multiplication is a popular primitive for ciphers targeted at software because many CPUs have built-in multiply instructions. In memory-constrained environments, multiplication is an attractive alternative to S-boxes, which are often implemented us- ing large tables. Multiplication has also been quite successful at foiling traditional dif- ¢ ¥ ¦ § ferential cryptanalysis, which considers pairs of messages of the form £ ¤ £ or ¢ ¨ ¦ § £ ¤ £ . These differentials behave well in ciphers that use xors, additions, or bit permutations, but they fall apart in the face of modular multiplication. Thus, we con- ¢ sider differential pairs of the form £ ¤ © £ § , which clearly commute with multiplication. The task of the cryptanalyst applying multiplicative differentials is to find values for © that allow the differential to pass through the other operations in a cipher. -
Applications of Search Techniques to Cryptanalysis and the Construction of Cipher Components. James David Mclaughlin Submitted F
Applications of search techniques to cryptanalysis and the construction of cipher components. James David McLaughlin Submitted for the degree of Doctor of Philosophy (PhD) University of York Department of Computer Science September 2012 2 Abstract In this dissertation, we investigate the ways in which search techniques, and in particular metaheuristic search techniques, can be used in cryptology. We address the design of simple cryptographic components (Boolean functions), before moving on to more complex entities (S-boxes). The emphasis then shifts from the construction of cryptographic arte- facts to the related area of cryptanalysis, in which we first derive non-linear approximations to S-boxes more powerful than the existing linear approximations, and then exploit these in cryptanalytic attacks against the ciphers DES and Serpent.

Approximation Schemes for Clustering with Outliers
Approximation Schemes for Clustering with Outliers Zachary Friggstad∗ Kamyar Khodamoradi Mohsen Rezapour Mohammad R. Salavatipoury Department of Computing Science University of Alberta Abstract Clustering problems are well-studied in a variety of fields such as data science, operations research, and computer science. Such problems include variants of centre location problems, k-median, and k-means to name a few. In some cases, not all data points need to be clustered; some may be discarded for various reasons. For instance, some points may arise from noise in a data set or one might be willing to discard a certain fraction of the points to avoid incurring unnecessary overhead in the cost of a clustering solution. We study clustering problems with outliers. More specifically, we look at uncapacitated facility location (UFL), k-median, and k-means. In these problems, we are given a set of data points in a metric space δ(:; :), a set of possible centres (each maybe with an openingX cost), maybe an integer parameter k, plus anC additional parameter z as the number of outliers. In uncapacitated facility location with outliers, we have to open some centres, discard up to z points of and assign every other point to the nearest open centre, minimizing the total assignment costX plus centre opening costs. In k-median and k-means, we have to open up to k centres but there are no opening costs. In k-means, the cost of assigning j to i is δ2(j; i). We present several results. Our main focus is on cases where δ is a doubling metric (this includes fixed dimensional Euclidean metrics as a special case) or is the shortest path metrics of graphs from a minor-closed family of graphs.
