description: Over a local ring $R$, the theory of cohomological support varieties attaches to any bounded complex $M$ of finitely generated $R$-modules an algebraic variety $V_R(M)$ that encodes homological properties of $M$. We give lower bounds for the dimension of $V_R(M)$ in terms of classical invariants of $R$. In particular, when $R$ is Cohen-Macaulay and not complete intersection we find that there are always varieties that cannot be realized as the cohomological support of any complex. When $M$ has finite projective dimension, we also give an upper bound for $ \dim V_R(M)$ in terms of the dimension of the radical of the homotopy Lie algebra of $R$. This leads to an improvement of a bound due to Avramov, Buchweitz, Iyengar, and Miller on the Loewy lengths of finite free complexes. Finally, we completely classify the varieties that can occur as the cohomological support of a complex over a Golod ring.

Efficient finite element response sensitivity analysis and applications in composites manufacturing
Creators: name: Bebamzadeh, Armin
Publisher: name: University of British Columbia
Year: 2009

description: This thesis presents the development, implementation, and application of response sensitivities in numerical simulation of composite manufacturing. The sensitivity results include both first- and second-order derivatives. Such results are useful in many applications. In this thesis, they are applied in reliability analysis, optimization analysis, model validation, model calibration, as well as stand-alone measures of parameter importance to gain physical insight into the curing and stress development process. In addition to novel derivations and implementations, this thesis is intended to facilitate and foster increased use of response sensitivities in engineering analysis. The work presented in this thesis constitutes an extension of the direct differentiation method (DDM). This is a method that produces response sensitivities in an efficient and accurate manner, at the one-time cost of deriving and implementing sensitivity equations alongside the ordinary response algorithm. In this thesis, novel extensions of the methodology are presented for the composite manufacturing problem. The derivations include all material, geometry, and processing parameters in both the thermochemical and the stress development algorithms. A state-of-the-art simulation software is developed to perform first-order sensitivity analysis for composite manufacturing problems using the DDM. In this software, several novel techniques are employed to minimize the computational cost associated with the response sensitivity computations. This sensitivity-enabled software is also used in reliability, optimization, and model calibration applications. All these applications are facilitated by the availability of efficient and accurate response sensitivities. The derivation and implementation of second-order sensitivity equations is a particular novelty in this thesis. It is demonstrated that it is computationally feasible to obtain second-order sensitivities (the “Hessian matrix”) by the DDM for inelastic finite element problems. It is demonstrated that the direct differentiation approach to the computation of first- and second-order response sensitivities becomes increasingly efficient as the problem size increases, compared with the less accurate and less efficient finite different approach.

Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: The suppression of the $ψ$(2S) nuclear modification factor has been seen as a trademark signature of final state effects in large collision systems for decades. In small systems, deviations of the nuclear modification from unity had been attributed to cold nuclear matter effects until the observation of strong differential suppression of the $ψ$(2S) state in $p/d+$A collisions, which suggests the presence of final state effects. In this paper, we present results of J/$ψ$ and $ψ$(2S) measurements in the dimuon decay channel for $p+p$, $p+$Al, and $p+$Au collision systems at $\sqrt{s_{_{NN}}}$ = 200 GeV. Key results include the nuclear modification factors $R_{pA}$ as a function of centrality and rapidity. The measurements are compared with shadowing and transport model predictions, as well as to complementary measurements at LHC energies.

description: A square matrix is said to be circular bidiagonal whenever (i) each nonzero entry is on the diagonal, or the subdiagonal, or in the top-right corner; (ii) each subdiagonal entry is nonzero, and the entry in the top-right corner is nonzero. Let $\mathbb F$ denote a field, and let $V$ denote a nonzero finite-dimensional vector space over $\mathbb F$. We consider an ordered pair of $\mathbb F$-linear maps $A: V \to V$ and $A^*: V \to V$ that satisfy the following two conditions: (i) there exists a basis for $V$ with respect to which the matrix representing $A$ is circular bidiagonal and the matrix representing $A^*$ is diagonal; (ii) there exists a basis for $V$ with respect to which the matrix representing $A^*$ is circular bidiagonal and the matrix representing $A$ is diagonal. We call such a pair a circular bidiagonal pair on $V$. We classify the circular bidiagonal pairs up to affine equivalence. There are two infinite families of solutions, which we describe in detail.

Diameter of Compact Riemann Surfaces

description: Diameter is one of the most basic properties of a geometric object, while Riemann surfaces are one of the most basic geometric objects. Surprisingly, the diameter of compact Riemann surfaces is known exactly only for the sphere and the torus. For higher genuses, only very general but loose upper and lower bounds are available. The problem of calculating the diameter exactly has been intractable since there is no simple expression for the distance between a pair of points on a high-genus surface. Here we prove that the diameters of a class of simple Riemann surfaces known as generalized Bolza surfaces of any genus greater than $1$ are equal to the radii of their fundamental polygons. This is the first exact result for the diameter of a compact hyperbolic manifold.
Reducing Blackwell and Average Optimality to Discounted MDPs via the Blackwell Discount Factor

description: We introduce the Blackwell discount factor for Markov Decision Processes (MDPs). Classical objectives for MDPs include discounted, average, and Blackwell optimality. Many existing approaches to computing average-optimal policies solve for discounted optimal policies with a discount factor close to $1$, but they only work under strong or hard-to-verify assumptions such as ergodicity or weakly communicating MDPs. In this paper, we show that when the discount factor is larger than the Blackwell discount factor $γ_{\mathrm{bw}}$, all discounted optimal policies become Blackwell- and average-optimal, and we derive a general upper bound on $γ_{\mathrm{bw}}$. The upper bound on $γ_{\mathrm{bw}}$ provides the first reduction from average and Blackwell optimality to discounted optimality, without any assumptions, and new polynomial-time algorithms for average- and Blackwell-optimal policies. Our work brings new ideas from the study of polynomials and algebraic numbers to the analysis of MDPs. Our results also apply to robust MDPs, enabling the first algorithms to compute robust Blackwell-optimal policies.
Electrical Breakdown of Excitonic Insulator

description: In this paper, we propose a new electrical breakdown mechanism for exciton insulators in the BCS limit, which differs fundamentally from the Zener breakdown mechanism observed in traditional band insulators. Our new mechanism results from the instability of the many-body ground state for exciton condensation, caused by the strong competition between the polarization and condensation energies in the presence of an electric field. We refer to this mechanism as ``many-body breakdown''. To investigate this new mechanism, we propose a BCS-type trial wave function under finite electric fields and use it to study the many-body breakdown numerically. Our results reveal two different types of electric breakdown behavior. If the system size is larger than a critical value, the Zener tunneling process is first turned on when an electrical field is applied, but the excitonic gap remains until the field strength reaches the critical value of the many-body breakdown, after which the excitonic gap disappears and the system becomes a highly conductive metallic state. However, if the system size is much smaller than the critical value, the intermediate tunneling phase disappears since the many-body breakdown happens before the onset of Zener tunneling. The sudden disappearance of the local gap leads to an ``off-on'' feature in the current-voltage ($I-V$) curve, providing a straightforward way to distinguish excitonic insulators from normal insulators.

description: H-index has become more popular nowadays and is used for some scientific performance criteria in the world widely. This indexing method does not correctly measure any performance or carrier specifications because of the parameters that are used to form the measurement basis. H-index is located based on citation(C) and paper(N) parameters that involve no logical criterion on the counting process and so measurement on this basis can only give quantity results not any quality information. Therefore, we need a new indexing instrument to find out also the scientific quality unique to an individual author even if that takes into account the effect of multiple coauthorships. Ipso facto, we create a new bibliometric indicator or academic performance indicator called the u-index.

description: We introduce a transformation of a Neural Radiance Field (NeRF) to an equivalent Poisson Point Process (PPP). This PPP transformation allows for rigorous quantification of uncertainty in NeRFs, in particular, for computing collision probabilities for a robot navigating through a NeRF environment. The PPP is a generalization of a probabilistic occupancy grid to the continuous volume and is fundamental to the volumetric ray-tracing model underlying radiance fields. Building upon this PPP representation, we present a chance-constrained trajectory optimization method for safe robot navigation in NeRFs. Our method relies on a voxel representation called the Probabilistic Unsafe Robot Region (PURR) that spatially fuses the chance constraint with the NeRF model to facilitate fast trajectory optimization. We then combine a graph-based search with a spline-based trajectory optimization to yield robot trajectories through the NeRF that are guaranteed to satisfy a user-specific collision probability. We validate our chance constrained planning method through simulations and hardware experiments, showing superior performance compared to prior works on trajectory planning in NeRF environments.

description: Quantum electrodynamics in $2+1$ dimensions (QED$_3$) has been proposed as a critical field theory describing the low-energy effective theory of a putative algebraic Dirac spin liquid or of quantum phase transitions in two-dimensional frustrated magnets. We provide compelling evidence that the intricate spectrum of excitations of the elementary but strongly frustrated $J_1$-$J_2$ Heisenberg model on the triangular lattice is in one-to-one correspondence to a zoo of excitations from QED$_3$, in the quantum spin liquid regime. This includes a large manifold of explicitly constructed monopole and bilinear excitations of QED$_3$, which is thus shown to serve as an organizing principle of phases of matter in triangular lattice antiferromagnets and their low-lying excitations. Moreover, we observe signatures of an emergent valence bond solid (VBS), which suggests a scenario where only the critical point of a transition from the $120^\circ$ Néel order to a VBS is described by QED$_3$. Our results are obtained by comparing ansatz wave functions from a parton construction to exact eigenstates obtained using large-scale exact diagonalization up to $N=48$ sites.

description: Magnetic skyrmions are promising for next-generation information storage and processing owing to their potential advantages in data storage density, robustness, and energy efficiency. The magnetic multilayers consisting of Pt, Co, and a third metal element $X$ provide an ideal platform to study the skyrmions due to their highly tunable magnetic properties. Here, we report the observation of room-temperature bubble-like Néel skyrmions in epitaxial Pt/Co/Cu multilayers in samples with multidomain states in zero field. The magneto-optic Kerr effect (MOKE) and superconducting quantum interference device (SQUID) magnetometry are applied to investigate the shapes of the hysteresis loops, the magnetic anisotropy, and the saturation magnetization. By tuning the Co thickness and the number of periods, we achieve perpendicular and in-plane magnetized states and multidomain states that are identified by a wasp-waisted hysteresis loop. Skyrmions are directly imaged by magnetic force microscopy (MFM) and Lorentz transmission electron microscopy (LTEM). The development of room-temperature skyrmions in Pt/Co/Cu multilayers may lead to advances in skyrmion-related research and applications.

description: We present an algorithm for fast generation of quasi-uniform and variable-spacing nodes on domains whose boundaries are represented as computer-aided design (CAD) models, more specifically non-uniform rational B-splines (NURBS). This new algorithm enables the solution of partial differential equations (PDEs) within the volumes enclosed by these CAD models using (collocation-based) meshless numerical discretizations. Our hierarchical algorithm first generates quasi-uniform node sets directly on the NURBS surfaces representing the domain boundary, then uses the NURBS representation in conjunction with the surface nodes to generate nodes within the volume enclosed by the NURBS surface. We provide evidence for the quality of these node sets by analyzing them in terms of local regularity and separation distances. Finally, we demonstrate that these node sets are well-suited (both in terms of accuracy and numerical stability) for meshless radial basis function generated finite differences (RBF-FD) discretizations of the Poisson, Navier-Cauchy, and heat equations. Our algorithm constitutes an important step in bridging the field of node generation for meshless discretizations with isogeometric analysis.

description: Let $p$ be a prime number, let $\mathcal{O}_F$ be the ring of integers of a finite field extension $F$ of $\mathbb{Q}_p$ and let $\mathcal{O}_K$ be a complete valuation ring of rank $1$ and mixed characteristic $(0,p)$. We introduce and study the "integral Hodge polygon", a new invariant of $p$-divisible groups $H$ over $\mathcal{O}_K$ endowed with an action $ι$ of $\mathcal{O}_F$. If $F|\mathbb{Q}_p$ is unramified, this invariant recovers the classical Hodge polygon and only depends on the reduction of $(H,ι)$ to the residue field of $\mathcal{O}_K$. This is not the case in general, whence the attribute "integral". The new polygon lies between Fargues' Harder-Narasimhan polygons of the $p$-power torsion parts of $H$ and another combinatorial invariant of $(H,ι)$ called the Pappas-Rapoport polygon. Furthermore, the integral Hodge polygon behaves continuously in families over a $p$-adic analytic space.

description: Schematic of the CellMapper SVD filter and algorithm. CellMapper first performs an SVD of the microarray expression matrix to extract major components of variation (singular vectors). Then it re-weights the components of variation based on their estimated relevance to the query gene, with larger weights given to components that are tightly correlated with the query gene (e.g. â  Component 3â   is highly correlated with the query gene expression pattern and receives a large weight). Then the microarray data are reconstructed from the components using the estimated weights. The result of this SVD filter is to emphasize the components of variation that most distinguish the query gene and dampen components that are less relevant to the given query. After the SVD filtering process, genes are ranked based on the Pearsonâ  s correlation of their transformed expression pattern to that of the query gene. (PDF 22 kb)

Sustainable road safety improvement through the promotion of an alternative mode : Okanagan Valley electric rail
Creators: name: Boozarjomehri, Elham
Publisher: name: University of British Columbia
Year: 2009

description: Across North America there is an increasing demand for safer, faster, less energy intensive and less costly modes of transportation. There are enormous social and economic costs associated with road collisions, which have been recognized world-wide as a serious problem. One local alternative to reduce auto use and resultant road collisions is the placement of a railway line through the Okanagan Valley in British Columbia, Canada, connecting Osoyoos and US railways in the south with Vernon and cross-Canada railways in the north. This line would not only be able to service Okanagan Valley commuters and tourists, currently served by Highway 97, but also provide an additional freight link between the United States and Canada. The objectives of this research were threefold: (1) To develop a set of macro-level collision prediction models for Highway 97, for use in calculating the Safety benefits of the proposed railway, (2) To conduct a comprehensive literature review of the design issues and costs of railway freight and passenger systems, and, (3) To conduct a social cost-benefit analysis of electric railways in Canada for a case study of the Okanagan Valley. To this end, a conceptual design, including route alignment, traffic forecast as well as a social benefit/cost analysis, was conducted. The paucity of data and studies for the Okanagan Valley regarding railway planning and engineering required several extrapolations from data reported in the literature. These estimates were made to gain insight into the data needed to conduct full scale analyses where gaps in knowledge exist, for the purpose of further research. The results of this research were in line with expectations. Regarding sustainable road safety, the development of macro-level collision prediction models for Highway 97 was successful. Regarding knowledge gaps, several were identified on traffic and cost data, and in freight forecast models. However, what was available allowed an order-of magnitude construction cost estimate of 990 million 2007 dollars for 176 kilometres of track. Moreover, if an electric railway began operating in 2050, the benefit/cost ratio of the project was estimated at 1.15, suggesting an Okanagan Valley railway warrants further research.

For a positive integer $m \le 4$ and given $x_1, \cdots, x_m \in \mathbb{Z}_p$, we determine the set of $m$-tuples of finitely generated $\mathbb{Z}_p$-modules $(H_1, \cdots, H_m)$ for which $(\text{cok}(A_n+px_1I_n), \cdots, \text{cok}(A_n+px_mI_n)) = (H_1, \cdots, H_m)$ for some matrix $A_n$. We also prove that if $A_n$ is an $n \times n$ Haar random matrix over $\mathbb{Z}_p$ for each positive integer $n$, then the joint distribution of $\text{cok}(A_n+px_iI_n)$ ($1 \le i \le m$) converges as $n \rightarrow \infty$.

description: Das beliebte Brettspiel „Mensch ärgere dich nicht“ ist im Grunde eine Monte-Carlo-Simulation. Diese Simulationen basieren im Allgemeinen auf einer Vielzahl von Wiederholungen zufälliger Ereignisse. In dem berühmten Brettspiel wird immer wieder mit derselben Wahrscheinlichkeit über das Ereignis entschieden, wie viele Felder die Figur vorrücken darf. Doch wie kann „Mensch ärgere dich nicht“ Wissenschaftler*innen dabei helfen, biologische Prozesse zu verstehen?

description: Optimizing static risk-averse objectives in Markov decision processes is difficult because they do not admit standard dynamic programming equations common in Reinforcement Learning (RL) algorithms. Dynamic programming decompositions that augment the state space with discrete risk levels have recently gained popularity in the RL community. Prior work has shown that these decompositions are optimal when the risk level is discretized sufficiently. However, we show that these popular decompositions for Conditional-Value-at-Risk (CVaR) and Entropic-Value-at-Risk (EVaR) are inherently suboptimal regardless of the discretization level. In particular, we show that a saddle point property assumed to hold in prior literature may be violated. However, a decomposition does hold for Value-at-Risk and our proof demonstrates how this risk measure differs from CVaR and EVaR. Our findings are significant because risk-averse algorithms are used in high-stake environments, making their correctness much more critical.

description: Robustness of CellMapper to query gene choice; companion figure to Fig. 1b. To test the sensitivity of CellMapper to the choice of query gene, we repeated our analysis for kidney podocytes using ten distinct query genes (MAFB and the nine positive control genes in Additional file 13) and then assessed how well each analysis recovered an independent, experimentally-defined set of podocyte genes in mouse [23]. This plot shows the area under the precision-recall curve (AUPR) achieved when using each of the ten query choices. For comparison, we included a dotted line for the AUPR achieved by in silico nano-dissection when given all ten query genes at once (light blue dotted line; the area under the light gray line in Fig. 1b), or when given the original training set of 47 positive control and 97 negative control genes (dark blue dotted line; the area under the dark gray line in Fig. 1b). All ten single query gene searches for CellMapper resulted in a higher AUPR than in silico nano-dissection achieved when given all ten of these genes at once. MAFB was selected as the primary query gene for podocytes in this study (i.e. the red line in Fig. 1b) because it was used by the Genitourinary Developmental Molecular Anatomy Project [57] (GUDMAP) for all podocyte labeling and isolation in their large evaluation across kidney cell types.

description: Die Rüsselkäfer des Tribus Cleonini sind überwiegend groß, attraktiv gefärbt – und dennoch bestens getarnt. Viele von ihnen leben in steppenartigen Biotopen. Mehrere Gattungen aus dieser Gruppe tragen folglich die deutsche Bezeichnung „Steppenrüssler“. Sie werden selten gefunden und sind zum Teil stark gefährdet. Der Heide-Steppenrüssler (Coniocleonus nebulosus) wurde im August 2020 in Sielmanns Naturlandschaft Kyritz-Ruppiner Heide erstmals seit Jahrzehnten wieder in Brandenburg entdeckt. Mit dem Sand-Steppenrüssler (Coniocleonus hollbergii) und dem Gefleckten Langrüssler (Cyphocleonus dealbatus) zählen mindestens zwei weitere Cleonini sogar zu den Charakterarten der Sandheiden und Bergbaufolgelandschaften Brandenburgs.
