description: A new diagnostic has been developed to investigate the wave-particle interaction in the phase-space in gyrokinetic particle-in-cell codes. Based on the projection of energy transfer terms onto the velocity space, the technique has been implemented and tested in the global code ORB5 and it gives an opportunity to localise velocity domains of maximum wave-plasma energy exchange for separate species. Moreover, contribution of different species and resonances can be estimated as well, by integrating the energy transfer terms in corresponding velocity domains. This Mode-Plasma-Resonance (MPR) diagnostic has been applied to study the dynamics of the Energetic-particle-induced Geodesic Acoustic Modes (EGAMs) in an ASDEX Upgrade shot, by analysing the influence of different species on the mode time evolution. Since the equations on which the diagnostic is based, are valid in both linear and nonlinear cases, this approach can be applied to study nonlinear plasma effects. As a possible future application, the technique can be used, for instance, to investigate the nonlinear EGAM frequency chirping, or the plasma heating due to the damping of the EGAMs.

description: Many reports suggest inclusion of polyphenol-rich plant extracts in feed improve performance and health in ruminants. Although these effects have been attributed to protein bypass of ruminal digestion, this mechanism cannot entirely explain the growth-promoting effect. Bovine rumen houses a complex microbiota able to convert indigestible plant mass into energy, which can be modulated by tannins. High-throughput sequencing of 16S rRNA gene (Illumina MiSeq platform) was used to study the temporal changes in rumen composition of six steers before and after addition of chestnut and quebracho tannins to diet. A total of 9.871.395 reads of 16S V3 region were obtained. Total number of phyla increased from 34 to 40 after tannins addition to diet. Moreover, Shannon’s diversity index increased significantly through time (p<0.05), concomitantly with a 5-fold reduction in its standard deviation, which shows that rumen microbiota acquired a higher complexity and was progressively stabilized after tannin treatment. Firmicutes correlated directly with time (R=0.95) and inversely with non-protein nitrogen levels (R=0.91). Moreover, a significant increase in the Firmicutes/Bacteroidetes ratio was observed over time from 0.77 to 1.10 (p<0.05), which has been shown to affect energy harvesting and fat production in different hosts. Ruminal tannins affected possitively the microbiome balance.

description: A key uncertainty in the design and development of magnetic confinement fusion energy reactors is predicting edge plasma turbulence. An essential step in overcoming this uncertainty is the validation in accuracy of reduced turbulent transport models. Drift-reduced Braginskii two-fluid theory is one such set of reduced equations that has for decades simulated boundary plasmas in experiment, but significant questions exist regarding its predictive ability. To this end, using a novel physics-informed deep learning framework, we demonstrate the first ever direct quantitative comparisons of turbulent field fluctuations between electrostatic two-fluid theory and electromagnetic gyrokinetic modelling with good overall agreement found in magnetized helical plasmas at low normalized pressure. This framework is readily adaptable to experimental and astrophysical environments, and presents a new technique for the numerical validation and discovery of reduced global plasma turbulence models.

Sustainable practices across leading Canadian universities

description: Educational institutions are the learning grounds both for current students and for generations to come. These establishments often play a significant role in shaping human behavior as values and practices adopted by students influence their actions and their future communities. Universities - being the premier knowledge producers in society - should therefore be the leaders in bringing and promoting sustainable practices and behaviour. Sustainable development, sometimes referred as “meeting the needs of the present without compromising the ability of future generations to meet their own needs” (World Commission on Environment and Development, 1987), has become an increasingly important consideration as evidence mounts that ecosystem degradation, natural resource depletion and global climate change threaten our ability to support society into the future. In this situation, the ability to foster sustainable behavior among all academic disciplines could be the single greatest contribution that universities can make towards a sustainable future. This is in addition to any facilities management-related activities that any large organisation can claim expertise over. Recognizing this, universities have increasingly focused on campus sustainability and mandated the creation of associated action plans. “It’s Greener Here” by University of Toronto, University of Waterloo Sustainability Project (UWSP), Social Ecological Economic Development Studies (SEEDS) by University of British Columbia are a few Canadian examples. However, due to the variety of approaches and scope of interventions, there is a great need to assess current sustainability practices. Hence, this paper reviews and analyzes Campus Sustainability Assessment Frameworks (CSAF) by leading Canadian universities with the objective of identifying current best practices. Based on this analysis, a campus sustainability assessment tool has been developed using multi-criteria decision making (MCDM) technique. The tool is then implemented for the purpose of drawing comparisons across the large volume of divergent campus sustainability indicators. These indicators are broadly classified into five thematic groups: research, education, infrastructure, campus operation, administration & community engagement. The implicit nature of MCDM makes it particularly suitable for this analysis as it permits the integration of the three well-known pillars of sustainability: economic, environmental and social and thus, provides a unified overall outcome. According to the analysis, all the universities under consideration have shown superior performance in infrastructure operation and community engagement while overall campus operation and designing sustainability focused curricula have got the least attention. By emphasizing the critical role of universities, this paper encourages the advancement of the sustainability agenda by moving closer to a “culture of continuous improvement”.

description: Petri networks and network models are two frameworks for the compositional design of systems of interacting entities. Here we show how to combine them using the concept of a "catalyst": an entity that is neither destroyed nor created by any process it engages in. In a Petri net, a place is a catalyst if its in-degree equals its out-degree for every transition. We show how a Petri net with a chosen set of catalysts gives a network model. This network model maps any list of catalysts from the chosen set to the category whose morphisms are all the processes enabled by this list of catalysts. Applying the Grothendieck construction, we obtain a category fibered over the category whose objects are lists of catalysts. This category has as morphisms all processes enabled by some list of catalysts. While this category has a symmetric monoidal structure that describes doing processes in parallel, its fibers also have premonoidal structures that describe doing one process and then another while reusing the catalysts.

description: Human-in-the-loop aims to train an accurate prediction model with minimum cost by integrating human knowledge and experience. Humans can provide training data for machine learning applications and directly accomplish tasks that are hard for computers in the pipeline with the help of machine-based approaches. In this paper, we survey existing works on human-in-the-loop from a data perspective and classify them into three categories with a progressive relationship: (1) the work of improving model performance from data processing, (2) the work of improving model performance through interventional model training, and (3) the design of the system independent human-in-the-loop. Using the above categorization, we summarize major approaches in the field; along with their technical strengths/ weaknesses, we have simple classification and discussion in natural language processing, computer vision, and others. Besides, we provide some open challenges and opportunities. This survey intends to provide a high-level summarization for human-in-the-loop and motivates interested readers to consider approaches for designing effective human-in-the-loop solutions.

description: We extend the notion of compositional associative rewriting as recently studied in the rule algebra framework literature to the setting of rewriting rules with conditions. Our methodology is category-theoretical in nature, where the definition of rule composition operations encodes the non-deterministic sequential concurrent application of rules in Double-Pushout (DPO) and Sesqui-Pushout (SqPO) rewriting with application conditions based upon $\mathcal{M}$-adhesive categories. We uncover an intricate interplay between the category-theoretical concepts of conditions on rules and morphisms, the compositionality and compatibility of certain shift and transport constructions for conditions, and thirdly the property of associativity of the composition of rules.

Fuzzy sets and presheaves

Publisher: name: arXiv
Year: 2019
Subjects: subject: Category Theory (math.CT)
subject: FOS: Mathematics

description: This note presents a presheaf theoretic approach to the construction of fuzzy sets, which builds on Barr's description of fuzzy sets as sheaves of monomorphisms on a locale. A presheaf-theoretic method is used to show that the category of fuzzy sets is complete and co-complete, and to present explicit descriptions of classical fuzzy sets that arise as limits and colimits. The Boolean localization construction for sheaves and presheaves on a locale L specializes to a theory of stalks if L approximates the structure of a closed interval in the real line. The system V(X) of Vietoris-Rips complexes for a data cloud X becomes both a simplicial fuzzy set and a simplicial sheaf in this general framework. This example is explicitly discussed in this paper, in stages.

Composing dynamic programming tree-decomposition-based algorithms
Creators: name: Baste, Julien
Publisher: name: arXiv
Year: 2019
Subjects: subject: Data Structures and Algorithms (cs.DS)
subject: FOS: Computer and information sciences

description: Given two integers $\ell$ and $p$ as well as $\ell$ graph classes $\mathcal{H}_1,\ldots,\mathcal{H}_\ell$, the problems $\mathsf{GraphPart}(\mathcal{H}_1, \ldots, \mathcal{H}_\ell,p)$, \break $\mathsf{VertPart}(\mathcal{H}_1, \ldots, \mathcal{H}_\ell)$, and $\mathsf{EdgePart}(\mathcal{H}_1, \ldots, \mathcal{H}_\ell)$ ask, given graph $G$ as input, whether $V(G)$, $V(G)$, $E(G)$ respectively can be partitioned into $\ell$ sets $S_1, \ldots, S_\ell$ such that, for each $i$ between $1$ and $\ell$, $G[S_i] \in \mathcal{H}_i$, $G[S_i] \in \mathcal{H}_i$, $(V(G),S_i) \in \mathcal{H}_i$ respectively. Moreover in $\mathsf{GraphPart}(\mathcal{H}_1, \ldots, \mathcal{H}_\ell,p)$, we request that the number of edges with endpoints in different sets of the partition is bounded by $p$. We show that if there exist dynamic programming tree-decomposition-based algorithms for recognizing the graph classes $\mathcal{H}_i$, for each $i$, then we can constructively create a dynamic programming tree-decomposition-based algorithms for $\mathsf{GraphPart}(\mathcal{H}_1, \ldots, \mathcal{H}_\ell,p)$, $\mathsf{VertPart}(\mathcal{H}_1, \ldots, \mathcal{H}_\ell)$, and $\mathsf{EdgePart}(\mathcal{H}_1, \ldots, \mathcal{H}_\ell)$. We apply this approach to known problems. For well-studied problems, like VERTEX COVER and GRAPH $q$-COLORING, we obtain running times that are comparable to those of the best known problem-specific algorithms. For an exotic problem from bioinformatics, called DISPLAYGRAPH, this approach improves the known algorithm parameterized by treewidth.

description: One of the most favourable extensions of General Relativity is the $f(R)$ gravity. $f(R)$ gravity in Palatini formalism can be a realistic alternative to the dark energy problem. In this work we study a recently introduced dark energy $f(R)$ gravity model along with two other models in cosmological perspectives under the Palatini formalism. First, we study the cosmic expansion history of these models with the help of the important cosmographic parameters, such as the Hubble parameter, luminosity distance, effective equation of state etc. This study shows that the new model behaves similarly with the other two models as well as with the $Λ$CDM model in some respects in the early or very early phases of the universe. It could predict the present accelerated expansion of the universe somewhat differently from the other models with a peculiar future history of the universe. Within a constrained range of parameters all models show a good agreement with the Union2.1 luminosity distance data. However, the new model shows a quite satisfactory agreement in the whole range of its allowed parameters than that of the other two models. We also obtain cosmological constraints on these models from the Observed Hubble Data. Further, models have been tested by using $Om(z)$ test and statefinder diagnostics. These diagnostics especially, the statefinder diagnostic shows that the evolutionary differences between these models are distinct. The evolutionary trajectories of the new model are completely different from the other two models we have considered.

description: A holistic approach of sustainability grounded in environmental concerns, also incorporates the dimensions of culture, economy, and social justice. It can be an added attraction bringing together various disciplines to explore pathways through which sustainability can be addressed in a practical manner. A one-week summer institute on Bioenergy and Bioproducts for educators from middle and high schools, and university faculty across STEAM (Science, Technology, Engineering, Agriculture, and Mathematics) disciplines was hosted by the University of Maryland Eastern Shore (UMES). This program is geared towards helping reform educational infrastructure by promoting multidisciplinary activities and content in the areas of sustainability, bioenergy, and bioproducts. The objectives of the Bioenergy Academy are: 1) to provide a systems-perspective in sustainability, bioenergy, and bioproducts education to STEAM educators and researchers; and 2) to develop and provide curricular materials and a set of teaching tools to educators for enhancing instruction in the areas of sustainable bioenergy and bioproducts. The Academy focuses on lessons and activities pertaining to sustainability, systems thinking, renewable energy with particular emphasis on bioenergy, bioproducts, and environment and policies related to energy issues. The participants got the opportunity to acquire concrete experiences involving teamwork, time management, and project execution skills; reflected on their learning experiences through presentations at the end of the institute; developed concepts related to organic chemistry, physics, engineering design, instrumentation, mathematics, biological, and environmental sciences; and actively experimented with feedstocks to generate biodiesel and environmentally-friendly soaps using the glycerin produced from the biodiesel. The BITES ( Buildings, Industry, Transportation, Electricity, Scenarios) simulation tool developed by National Renewable Laboratory (NREL) of the United States Department of Energy (DOE) and made freely available over the internet allowed participants to play out scenarios to reduce carbon foot print based on those situations that can be realized through policy decisions leading to building improvements, reduction of industrial pollution, use of alternative fuels, electric cars, and other design modifications in the transportation sector, and cleaner and more efficient conversion technologies for electricity generation and conservation. A total of forty one educators have been trained through this program over a period of four years. The evaluation surveys (pre-and post) revealed that the educators gained substantial knowledge in the fields of sustainability, bioenergy, and bioproducts, and felt comfortable in implementing the content in their courses and laboratories.

description: This paper generalises the treatment of compositional game theory as introduced by Ghani et al. in 2018, where games are modelled as morphisms of a symmetric monoidal category. From an economic modelling perspective, the notion of a game in the work by Ghani et al. is not expressive enough for many applications. This includes stochastic environments, stochastic choices by players, as well as incomplete information regarding the game being played. The current paper addresses these three issues all at once.

description: For an additive category $\mathbf{P}$ we provide an explict construction of a category $\mathcal{Q}( \mathbf{P} )$ whose objects can be thought of as formally representing $\frac{\mathrm{im}( γ)}{\mathrm{im}( ρ) \cap \mathrm{im}( γ)}$ for given morphisms $γ: A \rightarrow B$ and $ρ: C \rightarrow B$ in $\mathbf{P}$, even though $\mathbf{P}$ does not need to admit quotients or images. We show how it is possible to calculate effectively within $\mathcal{Q}( \mathbf{P} )$, provided that a basic problem related to syzygies can be handled algorithmically. We prove an equivalence of $\mathcal{Q}( \mathbf{P} )$ with the subcategory of the category of contravariant functors from $\mathbf{P}$ to the category of abelian groups $\mathbf{Ab}$ which contains all finitely presented functors and is closed under the operation of taking images. Moreover, we characterize the abelian case: $\mathcal{Q}( \mathbf{P} )$ is abelian if and only if it is equivalent to $\mathrm{fp}( \mathbf{P}^{\mathrm{op}}, \mathbf{Ab} )$, the category of all finitely presented functors, which in turn, by a theorem of Freyd, is abelian if and only if $\mathbf{P}$ has weak kernels.
 The category $\mathcal{Q}( \mathbf{P} )$ is a categorical abstraction of the data structure for finitely presented $R$-modules employed by the computer algebra system Macaulay2, where $R$ is a ring. By our generalization to arbitrary additive categories, we show how this data structure can also be used for modeling finitely presented graded modules, finitely presented functors, and some not necessarily finitely presented modules over a non-coherent ring.

description: Markov categories are a recent category-theoretic approach to the foundations of probability and statistics. Here we develop this approach further by treating infinite products and the Kolmogorov extension theorem. This is relevant for all aspects of probability theory in which infinitely many random variables appear at a time. These infinite tensor products $\bigotimes_{i \in J} X_i$ come in two versions: a weaker but more general one for families of objects $(X_i)_{i \in J}$ in semicartesian symmetric monoidal categories, and a stronger but more specific one for families of objects in Markov categories.
 As a first application, we state and prove versions of the zero-one laws of Kolmogorov and Hewitt-Savage for Markov categories. This gives general versions of these results which can be instantiated not only in measure-theoretic probability, where they specialize to the standard ones in the setting of standard Borel spaces, but also in other contexts.

description: In this paper we consider a weighted version of one dimensional discrete Hardy's Inequality on half-line with power weights of the form $n^α$. Namely we consider: \begin{equation} \sum_{n=1}^\infty |u(n)-u(n-1)|^2 n^α\geq c(α) \sum_{n=1}^\infty \frac{|u(n)|^2}{n^2}n^α\end{equation} We prove the above inequality when $α\in [0,1) \cup [5,\infty)$ with the sharp constant $c(α)$. Furthermore when $α\in [1/3,1) \cup \{0\}$ we prove an improved version of the above inequality. More precisely we prove \begin{equation} \sum_{n=1}^\infty |u(n)-u(n-1)|^2 n^α\geq c(α) \sum_{n=1}^\infty \frac{|u(n)|^2}{n^2} n^α+ \sum_{k=3}^\infty b_k(α) \sum_{n=2}^\infty \frac{|u(n)|^2}{n^k}n^α. \end{equation} for non-negative constants $b_k(α)$.

description: The partition function of three dimensional gravity in the quantum regime is dual to the Ising model when the central charge $c=1/2$. Mathematically, we show that the three dimensional gravity can be described by Schramm-Loewner Evolution(SLE) with certain $κ$. In fact, SLE depends on the parameter $κ$ which controls the diffusion of the Brownian motion. Each value of $c < 1$ corresponds to two values of $κ$, which may hint that the three dimensional gravity has two different phases at certain central charge c. Moreover, phase transition is also discussed in AdS and Ising model.

description: An open quantum system in contact with an infinite bath approaches equilibrium, while the state of the bath remains unchanged. If the bath is finite, the open system still relaxes to equilibrium, but it induces a dynamical evolution of the bath state. In this work, we study the dynamics of open quantum systems in contact with finite baths. We obtain a hierarchy of master equations that improve their accuracy by including more dynamical information of the bath. For instance, as the least accurate but simplest description in the hierarchy we obtain the conventional Born-Markov-secular master equation. Remarkably, our framework works even if the measurements of the bath energy are imperfect, which, not only is more realistic, but also unifies the theoretical description. Also, we discuss this formalism in detail for a particular non-interacting environment where the Boltzmann temperature and the Kubo-Martin-Schwinger relation naturally arise. Finally, we apply our hierarchy of master equations to study the central spin model.

description: We prove the nonlinear stability of the asymptotic behavior of perturbations of subfamilies of Kasner solutions in the contracting time direction within the class of polarised $T^2$-symmetric solutions of the vacuum Einstein equations with arbitrary cosmological constant $Λ$. This stability result generalizes the results proven in [3], which focus on the $Λ=0$ case, and as in that article, the proof relies on an areal time foliation and Fuchsian techniques. Even for $Λ=0$, the results established here apply to a wider class of perturbations of Kasner solutions within the family of polarised $T^2$-symmetric vacuum solutions than those considered in [3] and [26]. Our results establish that the areal time coordinate takes all values in $(0, T_0]$ for some $T_0 > 0$, for certain families of polarised $T^2$-symmetric solutions with cosmological constant.

description: A central problem in the study of resource theories is to find functions that are nonincreasing under resource conversions - termed monotones - in order to quantify resourcefulness. Various constructions of monotones appear in many different concrete resource theories. How general are these constructions? What are the necessary conditions on a resource theory for a given construction to be applicable? To answer these questions, we introduce a broad scheme for constructing monotones. It involves finding an order-preserving map from the preorder of resources of interest to a distinct preorder for which nontrivial monotones are previously known or can be more easily constructed; these monotones are then pulled back through the map. In one of the two main classes we study, the preorder of resources is mapped to a preorder of sets of resources, where the order relation is set inclusion, such that monotones can be defined via maximizing or minimizing the value of a function within these sets. In the other class, the preorder of resources is mapped to a preorder of tuples of resources, and one pulls back monotones that measure the amount of distinguishability of the different elements of the tuple (hence its information content). Monotones based on contractions arise naturally in the latter class, and, more surprisingly, so do weight and robustness measures. In addition to capturing many standard monotone constructions, our scheme also suggests significant generalizations of these. In order to properly capture the breadth of applicability of our results, we present them within a novel abstract framework for resource theories in which the notion of composition is independent of the types of the resources involved (i.e., whether they are states, channels, combs, etc.).

description: We present a new method for computing a smooth minimum distance function based on the LogSumExp function for point clouds, edge meshes, triangle meshes, and combinations of all three. We derive blending weights and a modified Barnes-Hut acceleration approach that ensure our method approximates the true distance, and is conservative (points outside the zero isosurface are guaranteed to be outside the surface) and efficient to evaluate for all the above data types. This, in combination with its ability to smooth sparsely sampled and noisy data, like point clouds, shortens the gap between data acquisition and simulation, and thereby enables new applications such as direct, co-dimensional rigid body simulation using unprocessed lidar data.

description: Beginning in 2002, the Kate Gleason College of Engineering (KGCOE) at the Rochester Institute of Technology (RIT) began implementing a series of sustainability themed curricular innovations. These innovations began in 2002 with the introduction of courses focused on sustainability, followed with the implementation of a programmatic minor in Sustainable Product Development in 2006, and culminated with the development and registration of the nation’s first Sustainable Engineering graduate programs in 2008. This article describes the genesis and maturation of KGCOE’s Sustainable Engineering graduate programs. The article reviews the early work that set the stage for the development of the new degree programs in Sustainable Engineering, and details the establishment and workings of the multidisciplinary faculty team that was charged with structuring the programs and marshalling them through the RIT curricular approval process and the New York State program registration process. These award winning programs have now been in place for over 7 years, and during that period they have evolved. This article describes the lessons learned along the program development path and highlights important program outcomes. Particular attention and reflection is devoted to the unusual demographic characteristics of the graduate student body that constitutes the programs. A comparison between the populations of these programs in sustainable engineering and those from other engineering departments in the same college is presented. The results indicate that the Sustainable Engineering programs are attracting a more diverse pool of students (with respect to academic preparation, national origin, and gender) than other KGCOE graduate programs.

description: Optics are bidirectional data accessors that capture data transformation patterns such as accessing subfields or iterating over containers. Profunctor optics are a particular choice of representation supporting modularity, meaning that we can construct accessors for complex structures by combining simpler ones. Profunctor optics have previously been studied only in an unenriched and non-mixed setting, in which both directions of access are modelled in the same category. However, functional programming languages are arguably better described by enriched categories; and we have found that some structures in the literature are actually mixed optics, with access directions modelled in different categories. Our work generalizes a classic result by Pastro and Street on Tambara theory and uses it to describe mixed V-enriched profunctor optics and to endow them with V-category structure. We provide some original families of optics and derivations, including an elementary one for traversals. Finally, we discuss a Haskell implementation.

description: We study the two-dimensional Yang--Mills theory with four supercharges in the large-$N$ limit. By using thermal boundary conditions, we analyze the internal energy and the distribution of scalars. We compare their behavior to the maximally supersymmetric case with sixteen supercharges, which is known to admit a holographic interpretation. Our lattice results for the scalar distribution show no visible dependence on $N$ and the energy at strong coupling appears independent of temperature.

description: We study a 3-dimensional stratum $\mathcal{M}_{3,V}$ of the moduli space $\mathcal{M}_3$ of curves of genus $3$ parameterizing curves $Y$ that admit a certain action of $V= C_2\times C_2$. We determine the possible types of the stable reduction of these curves to characteristic different from $2$. We define invariants for $\mathcal{M}_{3,V}$ and characterize the occurrence of each of the reduction types in terms of them. We also calculate the $j$-invariant (resp. the Igusa invariants) of the irreducible components of positive genus of the stable reduction of $Y$ in terms of the invariants.

description: We consider diffraction of waves on a product cone. We first show that diffractive waves enjoy a one-step polyhomogeneous asymptotic expansion, which is an improvement of Cheeger-Taylor's classical result of half-step polyhomogeneity of diffractive waves in [CT82a], [CT82b]. We also conclude that on product cones, the scattering matrix is the diffraction coefficient, which is the principal symbol of the diffractive half wave kernel, for strictly diffractively related points on the cross section. This generalize the result of Ford, Hassell and Hillairet in 2-dimensional flat cone settings [FHH18]. In the last section, we also give a radiation field interpretation of the relationship between the scattering matrix and the diffraction coefficient.

description: Prediction of protein-ligand binding affinity is a major goal in drug discovery. Generally, free energy gap is calculated between two states (e.g., ligand binding and unbinding). The energy gap implicitly includes the effects of changes in protein dynamics induced by the binding ligand. However, the relationship between protein dynamics and binding affinity remains unclear. Here, we propose a novel method that represents protein behavioral change upon ligand binding with a simple feature that can be used to predict protein-ligand affinity. From unbiased molecular simulation data, an unsupervised deep learning method measures the differences in protein dynamics at a ligand-binding site depending on the bound ligands. A dimension-reduction method extracts a dynamic feature that is strongly correlated to the binding affinities. Moreover, the residues that play important roles in protein-ligand interactions are specified based on their contribution to the differences. These results indicate the potential for dynamics-based drug discovery.
