description: The analysis and boundary optimal control of the nonlinear transport of gas on a network of pipelines is considered. The evolution of the gas distribution on a given pipe is modeled by an isothermal semilinear compressible Euler system in one space dimension. On the network, solutions satisfying (at nodes) the Kirchhoff flux continuity conditions are shown to exist in a neighborhood of an equilibrium state. The associated nonlinear optimization problem then aims at steering such dynamics to a given target distribution by means of suitable (network) boundary controls while keeping the distribution within given (state) constraints. The existence of local optimal controls is established and a corresponding Karush--Kuhn--Tucker (KKT) stationarity system with an almost surely non--singular Lagrange multiplier is derived.

description: The chapter discusses the applications using machine learning technologies
in various tasks of medical diagnostics and forecasting. Machine learning methods provide computer-made construction of algorithms predicting unknown target indicator by known values of another variables. Such algorithms generated from empirical regularities discovered in data. The chapter presents a short review of existing mainstream technologies including statistical
methods, artificial neural networks, classification trees and forests, Bayesian networks. Original technologies are based on collective solutions by sets of regularities. Questions of correct evaluation of diagnostic or predicting algorithms efficiency are discussed. Also the paper discusses existing methods of informative variables search.

description: We use a mean-field (Hartree-like) approach to study the conductance of a strongly localized electron system in two dimensions. We find a crossover between a regime where Coulomb interactions modify the conductance significantly to a regime where they are negligible. We show that under rather general conditions the conduction obeys a scaling relation which we verify using numerical simulations. The use of a Hartree self-consistent approach gives a clear physical picture, and removes the ambiguity of the use of single-particle tunneling density-of-states (DOS) in the calculation of the conductance. Furthermore, the theory contains interaction-induced correlations between the on site energy of the localized states and distances, as well as finite temperature corrections of the DOS.

description: The purpose of this game is to have fun and hopefully at the same time learn more about bit preservation. The goal for each player is to get through the years 2018 to 2050 without losing bit information. The players start by having a set-up of a bit preservation solution and an amount of money as well as a budget (in Bitros). On this basis, it is possible for the player to make adjustments; e.g. by choosing to invest in storage provider solution, or the player may be able to make alliances with other players in order to obtain partnerships that will mutually benefit the players bit preservation solution.

description: We will see that key concepts of number theory can be defined for arbitrary operations. We give a generalized distributivity for hyperoperations (usual arithmetic operations and operations going beyond exponentiation) and a generalization of the fundamental theorem of arithmetic for hyperoperations. We also give a generalized definition of the prime numbers that are associated to an arbitrary n-ary operation and take a few steps toward the development of its modulo arithmetic by investigating a generalized form of Fermat's little theorem. Those constructions give an interesting way to interpret diophantine equations and we will see that the uniqueness of factorization under an arbitrary operation can be linked with the Riemann zeta function. This language of generalized primes and composites can be used to restate and extend certain problems such as the Goldbach conjecture.

title: The Process of Tracking in Mathematics in Box Elder School District
Creators: name: Bushnell, Megan Haramoto

description: Educational policymakers have used tracking to instruct students in a variety of subjects, including mathematics. Tracking, which has also been called ability grouping, is a process by which students in the same grade are placed into different classes based on academic ability. Few educators and sociologists have looked at the process by which students are placed in different mathematics tracks. The research design of this study focused on accumulating, evaluating, and reporting the understanding and observations of 12 teachers and 4 counselors as they discussed their knowledge and involvement in the mathematics placement procedures from the intermediate and middle school levels in northern Utah. The data revealed that in addition to the official placement policies there were other factors that influenced the math placement. Those factors were teacher input, parental participation, and student involvement in the educational process. Educational administration, counselors, and teachers can use the results of this study to create more equitable placement policies and procedures for all students.

description: The basic concepts of systems theory are considered from the standpoint of a developer performing a specific project. A sequence of design decisions is proposed, which allows ensuring the integrity of the system at all stages of design. A construction based on a formal definition of the system and concepts of components, which allows fixing design solutions in a predetermined form, is proposed. The advantages of the matrix approach in solving practical problems are briefly outlined.
Capture of dark matter by the Solar System

description: We study the capture of galactic dark matter by the Solar System. The effect is due to the gravitational three-body interaction between the Sun, one of the planets, and a dark matter particle. The analytical estimate for the capture cross-section is derived and the upper and lower bounds for the total mass of the captured dark matter particles are found. The estimates for their density are less reliable. The most optimistic of them give an enhancement of dark matter density by about three orders of magnitudes compared to its value in our Galaxy. However, even this optimistic value remains below the best present observational upper limits by about two orders of magnitude.

description: From recent high resolution observations obtained with the Swedish 1 m Solar Telescope in La Palma, we detect swaying motions of individual filament threads in the plane of the sky. The oscillatory character of these motions are comparable with oscillatory Doppler signals obtained from corresponding filament threads. Simultaneous recordings of motions in the line of sight and in the plane of the sky give information about the orientation of the oscillatory plane. These oscillations are interpreted in the context of the magnetohydrodynamic theory. Kink magnetohydrodynamic waves supported by the thread body are proposed as an explanation of the observed thread oscillations. On the basis of this interpretation and by means of seismological arguments, we give an estimation of the thread Alfvén speed and magnetic field strength by means of seismological arguments.

description: We present Magnetic Resonance Force Microscopy (MRFM) measurements of Ferromagnetic Resonance (FMR) in a 50 nm thick permalloy film, tilted with respect to the direction of the external magnetic field. At small probe-sample distances the MRFM spectrum breaks up into multiple modes, which we identify as local ferromagnetic resonances confined by the magnetic field of the MRFM tip. Micromagnetic simulations support this identification of the modes and show they are stabilized in the region where the dipolar tip field has a component anti-parallel to the applied field.

description: This paper explores new methods for disambiguating the identity of individuals in classical Arabic citations (isnāds) using a network-based approach. After training a model to extract name mentions from classical Arabic, we embed these mentions in vector space using fine-tuned BERT representations and use community detection to infer clusters of coreferent mentions. The best-performing clustering approach reduces error on the CoNLL metric by 30%. Then, as a case study, we examine the problem of determining the number of direct transmitters to Ibn ʿAsākir (d. 1176) in a set of isnāds taken from the 12th century historical text Taʾrīkh Madīnat Dimashq (TMD, History of Damascus), using our method to replicate human judgement.

Implantation site and sex influences endocrine cell specification and function of pancreatic progenitor cells
Creators: name: Saber, Nelly Causing
Publisher: name: University of British Columbia

description: Diabetes affects over 500 million people worldwide. It is characterized by abnormally high blood glucose levels (hyperglycemia) due to the insufficient production or action of insulin. Hyperglycemia can eventually lead to cardiovascular issues, nerve damage, kidney failure, blindness, and other complications. Continuous blood glucose monitoring and exogenous insulin administration can help control blood glucose levels, but people living with diabetes still experience episodes of hyper- and hypoglycemia. Whole pancreas or islet transplantation can improve glycemic control but is limited by the scarcity of cadaveric donors. Human pluripotent stem cells are a potentially unlimited source of insulin-producing beta cells that could be used to treat people with diabetes. Clinical trials are currently underway testing the safety and efficacy of human stem cell-derived pancreatic progenitors in people with type 1 diabetes. Since pre-clinical animal studies mostly utilized male rodents and it has previously been shown that different factors can influence endocrine cell specification and function, the studies described in this thesis investigated whether the site of implantation and sex had an impact on the differentiation and maturation of pancreatic progenitors. Here I implanted pancreatic progenitors under the kidney capsule in male and female immunodeficient mice and found that these cells developed glucose-stimulated human insulin secretion sooner in females than males. However, I did not observe any sex differences in the acquisition of glucose-stimulated human insulin secretion when pancreatic progenitors were implanted in the gonadal fat pad or macroencapsulation devices, which are retrievable devices that serve to contain the cells. Additionally, despite the role of estrogen in beta cell development and function, there was no difference in the acquisition of glucose-stimulated human insulin secretion in ovariectomized and sham ovariectomized female mice. Furthermore, macroencapsulation devices appeared to promote the faster maturation of pancreatic progenitors compared to other implantation sites including under the kidney capsule or in the gonadal fat pad. Overall, it appears that the implantation site has more of an impact on the endocrine cell specification and function of pancreatic progenitor cells than the sex of the recipient in mice.
title: "Taking time seriously": an empirical approach to an American merchant network at the end of the 18th century
Creators: name: Bissieres, Louis
Publisher: name: Journal of Historical Network Research
Year: 2023

description: Network analysis tends to produce snapshots of structures that can seem permanent, not affected by time or change. Still, time matters in network history, and the observation of its effects is an issue. This paper explores way to assess the evolution of an American merchant network of the end of the eighteenth century. It builds on a database of transactions recorded in Levi Hollingsworth’s account books. Here, we develop a comparative analysis of five successive networks, through the use of some classical and some more innovative network metrics. We specifically question the stability of merchant networks in their composition and in their overall structure. We establish that, despite an intense turnover of members, they remained stable in their organization through time.

Why we fear wolves in sheep’s clothing : moral impression-violations threaten meaning
Creators: name: Guan, Kate Wen
Publisher: name: University of British Columbia
Year: 2024

description: When good people break character by committing egregious wrongs, observers often appear distressed by the revelation that someone may not be the person they seemed. Yet, research offers few accounts as to how or why they may feel negatively. The present research investigates the effects of moral impression-violations; that is, events in which seemingly moral (or immoral) actors commit unexpectedly immoral (or immoral) behaviors. I present a novel theory that moral impression-violations threaten observers’ epistemological certainty in what they know about the world and other people, threatening danger. Nine highly powered studies show that moral impression-violations lead observers to feel decreased confidence judging character, more negative moral impressions of others, and a sense of meaning violation following these events. Chapter 2 specifically investigate these outcomes and compares them relative to the effects of a moral impression-confirmation of an immoral actor committing immoral behaviors in line with previous expectations. Chapter 3 then assesses the effect of the direction of the impression-violation, finding that impression-violations that go from better to worse are more impactful than those that go from worse to better. Chapter 4 considers the uniqueness of these effects to the moral domain, finding mixed evidence that moral impression-violations may be more impactful than analogous competence ones. Finally, Chapter 5 explores how individual and cultural differences in perceivers’ backgrounds moderate the severity of effects that they experience following these moral impression-violations from better to worse. My results contribute to ongoing research showing the importance of morality in people’s understanding of others and the world around them, and shed light on why even seemingly innocuous revelations about others’ characters can feel threatening.
Two models of spin glasses -- Ising versus Heisenberg

description: Brief review is given on recent numerical research of the ordering of two typical models of spin glasses (SGs), the three-dimensional (3D) Ising SG and the 3D Heisenberg SG models. Particular attention is paid to the questions of whether there is a thermodynamic transition in zero field, what are the associated critical properties, what is the nature of the ordered state, particularly of a possible replica-symmetry breaking, and whether there is a thermodynamic transition in applied fields. The properties of the two models are contrasted, and possible relation to experiments is discussed.

title: Assortative Mixing in the Social Networks of Athenian Potters and the Search for Communities of Practice
Creators: name: Harris Cline, Diane
name: Hasaki, Eleni
Publisher: name: Journal of Historical Network Research
Year: 2023

description: As co-directors of the Social Networks of Athenian Potters (SNAP) project from 2017-2021, we have experimented with social network analysis to map the networks of painters and potters in Archaic and Classical Athens dating between 600−400 BCE (snap.sbs.arizona.edu). We use sociograms to visualize connections between the artists and SNA metrics to understand individuals’ roles in network terms, find clusters within the components, and then learn more about the topology and characteristics of the network as a whole. The data is derived from catalogues of vase painters who worked in the Kerameikos of ancient Athens, using the techniques called black-figure and red-figure. We have previously published the black-figure elsewhere; here we are concerned with the non-directed bimodal red-figure network composed of 13 components with 1,067 nodes and 1,583 edges. Most of the sociogram shows disassortative mixing, but we have identified one area which appears to be assortative and which we believe draws as close as possible to being representative of a social network of a community of contemporary craftsmen, to the extent our data allows. This group of 70 artists with 94 ties between them is unusual in terms of its topological structure. The rest of the red-figure network appears to be disassortative, with high degree nodes in the center of a cluster and low degree affiliates. These hubs rarely link directly to other hubs in one degree. This network structure may reflect the master artist and his relationships with minor artists, though it could also simply visualize shapes of vases and the many artists working on that shape; it is also possible that it just reflects the bias of our source, i.e., Beazley’s published volumes. Limitations of applying SNA to material from 2,500 years ago emerge. Many historical SNA projects also have such problems and limitations, so here we present the challenges involved with working with incomplete data sets and how we chose to manage them. The decisions and choices that we made are presented here knowing that others may have addressed the problems differently and so we welcome further discussions.

description: Agricultural trade between the United States and Mexico underwent many changes in 2020 in the face of the Coronavirus (COVID-19) pandemic. Overall, U.S. agricultural exports to Mexico declined in April 2020 and did not recover until November 2020. Meanwhile, U.S. agricultural imports from Mexico declined in April and May 2020 before resuming their long-term upward trend. Beef and veal, cotton, and pork were the U.S. agricultural exports to Mexico with the largest decreases in export value between calendar years 2019 and 2020. The agricultural imports from Mexico with the largest increases in import value were tequila, fresh tomatoes, and beer. The economic downturn and shift away from food expenditures at hotels, restaurants, and institutional establishments because of the pandemic explain some of these changes. However, a larger set of supply and demand determinants was at play, including conventional factors unrelated to the pandemic, such as the long-term expansion of Mexico’s horticultural export sector and year-to-year changes in crop production.
Many-body instability of Coulomb interacting bilayer graphene: RG approach

description: Low-energy electronic structure of (unbiased) bilayer graphene is made of two Fermi points with quadratic dispersions, if trigonal-warping and other high order contributions are ignored. We show that as a result of this qualitative difference from single-layer graphene, short-range (or screened Coulomb) interactions are marginally relevant. We use renormalization group to study their effects on low-energy properties of the system, and show that the two quadratic Fermi points spontaneously split into four Dirac points, at zero temperature. This results in a nematic state that spontaneously breaks the six-fold lattice rotation symmetry (combined with layer permutation) down to a two-fold one, with a finite transition temperature. Critical properties of the transition and effects of trigonal warping are also discussed.

Toward a dynamical shift condition for unequal mass black hole binary simulations

Year: 2009
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Moving puncture simulations of black hole binaries rely on a specific gauge choice that leads to approximately stationary coordinates near each black hole. Part of the shift condition is a damping parameter, which has to be properly chosen for stable evolutions. However, a constant damping parameter does not account for the difference in mass in unequal mass binaries. We introduce a position dependent shift damping that addresses this problem. Although the coordinates change, the changes in the extracted gravitational waves are small.

description: We investigate the geometric properties of loops on two-dimensional lattice graphs, where edge weights are drawn from a distribution that allows for positive and negative weights. We are interested in the appearance of spanning loops of total negative weight. The resulting percolation problem is fundamentally different from conventional percolation, as we have seen in a previous study of this model for the undiluted case. Here, we investigate how the percolation transition is affected by additional dilution. We consider two types of dilution: either a certain fraction of edges exhibit zero weight, or a fraction of edges is even absent. We study these systems numerically using exact combinatorial optimization techniques based on suitable transformations of the graphs and applying matching algorithms. We perform a finite-size scaling analysis to obtain the phase diagram and determine the critical properties of the phase boundary. We find that the first type of dilution does not change the universality class compared to the undiluted case whereas the second type of dilution leads to a change of the universality class.

description: The exact solution for the energy spectrum of a one-dimensional Hamiltonian with local two-site interactions and periodic boundary conditions is determined. The two-site Hamiltonians commute with the symmetry algebra given by the Drinfeld double D(D_3) of the dihedral group D_3. As such the model describes local interactions between non-Abelian anyons, with fusion rules given by the tensor product decompositions of the irreducible representations of D(D_3). The Bethe ansatz equations which characterise the exact solution are found through the use of functional relations satisfied by a set of mutually commuting transfer matrices.

A Controllable Interaction between Two-Level Systems inside a Josephson Junction

description: Two-level system fluctuators (TLS's) in the tunnel barrier of a Josephson junction have recently been demonstrated to cause novel energy splittings in spectroscopic measurements of superconducting phase qubits. With their strong coupling to the Josephson junction and relatively long decoherence times, TLS's can be considered as potential qubits and demonstrate coherent quantum effects. Here, we study the effective interaction between the TLS qubits that is mediated by a Josephson junction resonator driven by an external microwave source. This effective interaction can enable controlled quantum logic gates between the TLS's. Our study can be extended to other superconducting resonators coupling with TLS's.
