description: We propose a computational method to simulate anomalous self-diffusion in a simple liquid. The method is based on a molecular dynamics simulation on which we impose the following two conditions: firstly, the inter-particle interaction is described by a soft-core potential and secondly, the system is forced out of equilibrium. The latter can be achieved by subjecting the system to changes in the length scale at intermittent times. In many respects, our simulation system bears resemblance to slowly driven sandpile models displaying self-organised criticality. We find non-Gaussian single time step displacement distributions during the out-of-equilibrium time periods of the simulation.

Theory of single spin inelastic tunneling spectroscopy

description: Recent work shows that inelastic electron scanning tunneling microscope (STM) probes the elementary spin excitations of a single and a few magnetic atoms in a thin insulating layer. Here I show that this new type of spectroscopy is described using a phenomenological spin-assisted tunneling Hamiltonian. Within this formalism, the inelastic $dI/dV$ lineshape is related to the spin spectral weight of the probed magnetic atom. This accounts for the spin selection rules observed experimentally. The theory agrees well with existing STM experiments for single Fe and Mn atoms as well as linear chains a few Mn atoms. The magnetic anisotropy in the inelastic $dI/dV$ and the marked odd-even $N$ effects are accounted for by the theory.

description: We report on the determination of the electronic heat capacity of a slightly overdoped (x = 0.075) Ba(Fe1-xCox)2As2 single crystal with a Tc of 21.4 K. Our analysis of the temperature dependence of the superconducting-state specific heat provides strong evidence for a two-band s-wave order parameter with gap amplitudes 2D1(0)/kBTc=1.9 and 2D2(0)/kBTc=4.4. Our result is consistent with the recently predicted s+- order parameter [I. I. Mazin et al., Phys. Rev. Lett. 101, 057003 (2008)].

description: The evolution of a heavy ion collision passes close to the O(4) critical point of QCD, where fluctuations of the order parameter are expected to be enhanced. Using the appropriate stochastic hydrodynamic equations in mean field near the the pseudo-critical point, we compute how these enhanced fluctuations modify the transport coefficients of QCD. Finally, we estimate the expected critical enhancement of soft pion yields, which provides a plausible explanation for the excess seen in experiment relative to ordinary hydrodynamic computations.

A status survey of reading programs in British Columbia secondary schools : 1976
Creators: name: Kinzer, Charles K.
Publisher: name: University of British Columbia
Year: 2010

description: This study is a descriptive survey of secondary reading programs in British Columbia. A review of the literature indicated that secondary reading programs were largely remedial or developmental in nature, with teachers of such programs having little training in reading education. All 331 secondary schools in the province of British Columbia were surveyed using a modified version of Hill's (1975) questionnaires, Responses were sought from the school administrators. A stamped, addressed return envelope was included with the questionnaire. An initial and follow-up mailing yielded a return of 88.8%. Results wers analysed through the University of British Columbia's computer facilities using the standard Laboratory Of Educational Research Test Analysis Package and the Multivariate Contingency Tabulations computer programs. The results for the population used in this study are in general agreement with the finding noted in the review of the literature. The majority of secondary reading programs in the province are remedial and/or developmental in nature. Many administrators- are dissatisfied with the existing reading programs in their schools. Most teachers of secondary reading were found to have little training in reading instruction. A comparison of available secondary reading programs, teacher training, administrators' attitudes toward reading programs, and availability of special, in-school reading facilities is made between junior and senior secondary schools.

description: Artificial Intelligence (AI) is revolutionizing business management by enabling data-driven decisions, streamlining operations, and enhancing strategic planning. This paper explores the intersection of management and AI, investigating how AI technologies influence managerial roles, decision-making, organizational performance, and workforce dynamics. Using qualitative and quantitative research methodologies, the study provides insights into AI’s practical applications and its limitations within managerial contexts. The findings suggest that while AI improves operational efficiency and predictive accuracy, it also raises challenges related to ethics, employee adaptation, and data privacy. The paper concludes by highlighting the need for a balanced, human-centric AI integration in modern management practices.

description: Classical and quantum Friedmann-Lemaître-Robertson-Walker universes filled with non-interacting radiation and dust fluids are considered in the framework of Hořava-Lifshitz gravity theory. The Hořava-Lifshitz theory is set in its projectable version and without detailed balance condition. Canonical quantization is performed in the Wheeler-DeWitt approach of quantum cosmology for a minisuperspace model in the light of de Broglie-Bohm interpretation of quantum mechanics. The main results are analytical solutions for non-singular quantum bounce and cyclic universes for open and closed spatial sections in terms of the parameters of Hořava-Lifshitz theory.

description: The local chemistry, structure, and magnetism of (Ga,Fe)N nanocomposites grown by metal organic vapor phase epitaxy is studied by high resolution synchrotron x-ray diffraction and absorption, transmission electron microscopy, and superconducting quantum interference device magnetometry as a function of the growth temperature $T_{\mathrm{g}}$. Three contributions to the magnetization are identified: i) paramagnetic -- originating from dilute and non-interacting Fe$^{3+}$ ions substitutional of Ga, and dominating in layers obtained at the lowest considered $T_{\mathrm{g}}$ (800$^{\circ}$C); ii) superparamagnetic-like -- brought about mainly by ferromagnetic nanocrystals of $ε-$Fe$_3$N but also by $γ'$-Fe$_4$N and by inclusions of elemental $α$- and $γ$-Fe, and prevalent in films obtained in the intermediate $T_{\mathrm{g}}$ range; iii) component linear in the magnetic field and associated with antiferromagnetic interactions -- found to originate from highly nitridated Fe$_x$N ($x \leq$ 2) phases, like $ζ$-Fe$_2$N, and detected in samples deposited at the highest employed temperature, $T_{\mathrm{g}}$ = 950$^{\circ}$C. Furthermore, depending on $T_{\mathrm{g}}$, the Fe-rich nanocrystals segregate towards the sample surface or occupy two-dimensional planes perpendicular to the growth direction.

description: We study the competition between interference due to multiple single-particle paths and Coulomb interaction in a simple model of an Anderson-like impurity with local-magnetic-field-induced level splitting coupled to ferromagnetic leads. The model along with its potential experimental relevance in the field of spintronics serves as a nontrivial benchmark system where various quantum transport approaches can be tested and compared. We present results for the linear conductance obtained by a spin-dependent implementation of the density matrix renormalization group scheme which are compared with a mean-field solution as well as a seemingly more advanced Hubbard-I approximation. We explain why mean-field yields nearly perfect results, while the more sophisticated Hubbard-I approach fails, even at a purely conceptual level since it breaks hermiticity of the related density matrix. Furthermore, we study finite bias transport through the impurity by the mean-field approach and recently developed higher-order density matrix equations. We find that the mean-field solution fails to describe the plausible results of the higher-order density matrix approach both quantitatively and qualitatively as it does not capture some essential features of the current-voltage characteristics such as negative differential conductance.

description: The measurement by the BES collaboration of J/psi -> gamma p pbar decays indicates an enhancement at the p-pbar threshold. In another experiment BES finds a peak in the invariant mass of pi-mesons produced in the possibly related decay J/psi -> gamma pi+ pi- eta'. Using a semi-phenomenological potential model which describes all the N-Nbar scattering data, we show that the explanation of both effects may be given by a broad quasi-bound state in the spin and isospin singlet S wave. The structure of the observed peak is due to an interference of this quasi-bound state with a background amplitude and depends on the annihilation mechanism.

description: This study introduces a method to enhance feature-based machine learning models in materials science by incorporating graph neural networks (GNNs) as fast featurizers. This approach merges the interpretability of feature-based models with the accuracy of GNNs, creating a powerful tool for materials informatics. It includes three independent techniques for constructing GNN featurizers: compressing electronic structure descriptors, integrating pretrained GNN models, and incorporating task-specific GNNs. These featurizers, combined with traditional chemical and geometrical features, improve prediction accuracy while preserving interpretability. MODNet served as the base feature-based model, with MEGNet GNN models functioning as featurizers. The method was evaluated for predicting the heat of formation in perovskites, reducing the mean absolute error by 44.2% compared to the default MODNet featurizer, and by 27.7% compared to direct use of the MEGNet model. It also showed generalizability on more complex tasks, such as predicting convex hull distance and band gaps of halogen-containing materials from the OQMD dataset. Additionally, feature importance analysis using SHAP plots and surrogate models helped recover partial interpretability by extracting chemical insights from GNN features. This method represents a significant step forward for feature-based models in materials science, enabling more accurate, efficient, and interpretable predictions. By leveraging pretrained GNNs, lowering featurization costs, and improving accuracy, it opens the door to more targeted materials design and optimization.

description: We argue that the existence of Dark Matter (DM) is a possible consequence of GUT symmetry breaking. In GUTs like SO(10), discrete Z_2 matter parity (-1)^{3(B-L)} survives despite of broken B-L, and group theory uniquely determines that the only possible Z_2-odd matter multiplets belong to representation 16. We construct the minimal non-SUSY SO(10) model containing one scalar 16 for DM and study its predictions below M_{G}. We find that EWSB occurs radiatively due to DM couplings to the SM Higgs boson. For thermal relic DM the mass range M_{DM}\sim (0.1-1) TeV is predicted by model perturbativity up to M_{G}. For M_{DM}\sim (1) TeV to explain the observed cosmic ray anomalies with DM decays, there exists a lower bound on the spin-independent direct detection cross section within the reach of planned experiments.
description: DM direct detection cross section is corrected by adding s-quark contribution which turned out to be the dominant one. The prediction is just below the present CDMS and XENON10 bound. Extended version, RGE-s included, new references added

description: The addition of a high intensity 11 GeV polarized positron beam at the Continuous Electron Beam Accelerator Facility (CEBAF) at JLAB would allow for a search of Charged Lepton Flavor Violation (CLFV) via the process $e^+N \rightarrow μ^+ X$. The proposed Solenoidal Large Intensity Detector (SoLID) spectrometer, in the configuration with muon chambers, would be ideal for such CLFV searches. Various new physics scenarios, including the phenomenologically convenient Leptoquark (LQ) framework, predict CLFV rates that are within reach of current or planned experiments. A positron beam with instantaneous luminosity, ${\cal L}\sim 10^{38}$ cm$^{-2}$s$^{-1}$, could improve on existing HERA limits by two or three orders of magnitude. The availability of positron beam polarization would also allow for distentangling CLFV effects mediated by left-handed vs. right-handed LQs.

description: The spin-1/2 transverse field two-leg Ising ladder with nearest-neighbor exchange and plaquette four-spin interaction $J_{4}$ is studied analytically and numerically with the density matrix renormalization group approach. The quantum phase diagram in the transverse field $B$ versus $J_{4}$ plane has been obtained. There are three different phases: a paramagnetic (PM) phase for high values of the transverse field and, for low values of $B$, a ferromagnetic (FM) ordered phase for small $J_{4}$ and a dimerized-rung (DR) phase for large negative values of $J_{4}$. All phases are separated by quantum phase transition lines meeting at a multicritical point. The critical lines have been obtained by exploring the entanglement entropy. The results show that along the critical lines the central charge is $c=1/2$, while at the multicritical point one has $c=1$. The scaling dimension of the energy operator is $X_ε=1$, in agreement with the universality class of the critical behavior of the quantum Ising chain. An effective field theory for the multicritical point is also discussed. The FM and the DR order parameters have also been computed and we found a region where the FM and the DR phases coexist.

description: A coupled-channel approach including the $Λ_c\bar{D}^{(*)}$ and $η_c p$ channels in addition to the $Σ_c^{(*)}\bar{D}^{(*)}$ and $J/ψp$ channels, as required by unitarity and heavy quark spin symmetry (HQSS), is applied to the hidden-charm pentaquark $P_c$ states, i.e., $P_c(4312)$, $P_c(4440)$ and $P_c(4457)$, discovered by LHCb Collaboration. It is demonstrated that to obtain cutoff independent results, the one-pion exchange potential in the multichannel systems is to be supplemented with next-leading order counter terms responsible for the $S$-wave-to-$D$-wave transitions. We show that the experimental data for the $J/ψp$ mass distributions are fully in line with the $Σ_c\bar{D}$ and $Σ_c\bar{D}^*$ hadronic molecular interpretation of the $P_c(4312)$ and $P_c(4440)/P_c(4457)$, respectively. A narrow $Σ_c^*\bar{D}$ molecule around 4.38 GeV is required by the HQSS with the evidence for its existence seen in the $J/ψp$ spectrum. Moreover, we predict the line shapes for the elastic and inelastic channels.

description: Magnetic reconnection is a universal process that powers explosive energy release events such as solar flares, geomagnetic substorms, and some astrophysical jets. A characteristic feature of magnetic reconnection is the production of fast reconnection outflow jets near the plasma Alfvén speeds. In eruptive solar flares, dark, finger-shaped plasma downflows moving toward the flare arcade have been commonly regarded as the principal observational evidence for such reconnection-driven outflows. However, they often show a speed much slower than that expected in reconnection theories, challenging the reconnection-driven energy release scenario in standard flare models. Here, we present a three-dimensional magnetohydrodynamics model of solar flares. By comparing the model-predictions with the observed plasma downflow features, we conclude that these dark downflows are self-organized structures formed in a turbulent interface region below the flare termination shock where the outflows meet the flare arcade, a phenomenon analogous to the formation of similar structures in supernova remnants. This interface region hosts a myriad of turbulent flows, electron currents, and shocks, crucial for flare energy release and particle acceleration.
The categorization of the speech sounds of English by non-native children
Creators: name: Early, Margaret Mary
Publisher: name: University of British Columbia

description: This research investigates the categorization of English speech sounds by young non-native children. The fundamental thesis is that non-native children, like native children (Read 1970), can organize their perceptions of the phonetic features of English in a way which is consistent and is systematic, (that is, based on categorical judgments, phonetic perceptions or a knowledge of the phonological rules of English). The research of other investigators was examined for insights. The evidence presented consists of spellings invented by thirteen non-native children five to nine years old, who composed stories and messages by choosing alphabetic correlates for the sounds they perceive. The results of this experiment were analyzed to determine the sources of error, the children's knowledge and perceptions of English speech sounds and the degree of similarity to Read's (1970) results. The significance of the research for the teaching of literacy was discussed together with an account of the development of the spellings.

description: We consider the problem of partitioning the set of vertices of a given unit disk graph (UDG) into a minimum number of cliques. The problem is NP-hard and various constant factor approximations are known, with the current best ratio of 3. Our main result is a {\em weakly robust} polynomial time approximation scheme (PTAS) for UDGs expressed with edge-lengths, it either (i) computes a clique partition or (ii) gives a certificate that the graph is not a UDG; for the case (i) that it computes a clique partition, we show that it is guaranteed to be within $(1+\eps)$ ratio of the optimum if the input is UDG; however if the input is not a UDG it either computes a clique partition as in case (i) with no guarantee on the quality of the clique partition or detects that it is not a UDG. Noting that recognition of UDG's is NP-hard even if we are given edge lengths, our PTAS is a weakly-robust algorithm. Our algorithm can be transformed into an $O(\frac{\log^* n}{\eps^{O(1)}})$ time distributed PTAS. We consider a weighted version of the clique partition problem on vertex weighted UDGs that generalizes the problem. We note some key distinctions with the unweighted version, where ideas useful in obtaining a PTAS breakdown. Yet, surprisingly, it admits a $(2+\eps)$-approximation algorithm for the weighted case where the graph is expressed, say, as an adjacency matrix. This improves on the best known 8-approximation for the {\em unweighted} case for UDGs expressed in standard form.

Shifting Notions of Life and the Illusion of Choice: Neoliberalism or Neofascism in Italy?

description: I argue that contemporary Italy and Europe is in state of “interregnum,” in between two different epochs (an age of industrialization and one of digitalization), and that this “non-event” impacts the ways in which individuals perceive themselves and Otherize. I argue such a period entails a certain “disorientation,” or what Gramsci called “morbid symptoms (Gramsci 2009).” Drawing on a database of certain keywords taken from Italian newspapers over the span of 20 years (2000- 2020), I show how the notion of crisis gets played out by state actors and media corporations as a narrative to “orient” the population.

description: We present an analysis of a large sample of AGN environments at z~1 using stacked Spitzer data at 3.6um. The sample contains type-1 and type-2 AGN in the form of quasars and radio galaxies, and spans a large range in both optical and radio luminosity. We find, on average, that 2 to 3 massive galaxies containing a substantial evolved stellar population lie within a 200-300 kpc radius of the AGN, constituting a >8-sigma excess relative to the field. Secondly, we find evidence for the environmental source density to increase with the radio luminosity of AGN, but not with black-hole mass. This is shown first by dividing the AGN into their classical AGN types, where we see more significant over-densities in the fields of the radio-loud AGN. If instead we dispense with the classical AGN definitions, we find that the source over-density as a function of radio luminosity for all our AGN exhibits a positive correlation. One interpretation of this result is that the Mpc-scale environment is in some way influencing the radio emission that we observe from AGN. This could be explained by the confinement of radio jets in dense environments leading to enhanced radio emission or, alternatively, may be linked to more rapid black-hole spin brought on by galaxy mergers.

description: Various ocular diseases and high myopia influence the anatomical reference point Foveal Avascular Zone (FAZ) dimensions. Therefore, it is important to segment and quantify the FAZs dimensions accurately. To the best of our knowledge, there is no automated tool or algorithms available to segment the FAZ's deep retinal layer. The paper describes a new open-access software with a user-friendly Graphical User Interface (GUI) and compares the results with the ground truth (manual segmentation).

description: We present an analysis of non-leptonic B decays in the minimally flavour-violating MSSM with large tan(beta). We relate the Wilson coefficients of the relevant hadronic scalar operators to leptonic observables, showing that the present limits on the Bs->mu+ mu- and B+->tau nu_tau branching fractions exclude any visible effect in hadronic decays. We study the transverse helicity amplitudes of B->VV decays, which exhibit an enhanced sensitivity to the scalar operators, showing that even though an order one modification relative to the SM is not excluded in some of these amplitudes, they are too small to be detected at B factories.

title: Simplified Implementation of Energy-Aware Production Scheduling in Job Shops
Creators: name: Grosch, Benedikt Emanuel
Publisher: name: UNSPECIFIED
Year: 2023

description: Climate change presents a pressing global challenge, necessitating urgent actions to reduce greenhouse gas emissions and limit global warming. As a significant energy consumer, the industrial sector plays a crucial role in advancing sustainable practices and mitigating the impact of climate change. In this context, this thesis focuses on developing an implementation procedure and an energy-aware production scheduling system architecture to optimize production schedules while considering production-related and energy-related objectives.

The research goal of this thesis is to simplify the implementation of energy-aware production scheduling systems in real production systems. To achieve this, the thesis addresses three key research areas: (1) to find whether the absence of standardized procedures and architectures hinders the implementation of energy-aware production scheduling systems for job shops, (2) to propose a standardized and partially automated implementation procedure for energy-aware production scheduling, and (3) to design an architecture supporting the implementation procedure.

The proposed implementation procedure includes a structured system configuration and deployment approach, ensuring alignment with stakeholder requirements. It comprises three phases: discovery and planning, development and configuration, and testing and deployment. The energy-aware production scheduling system architecture implements a cyber-physical production system with a virtual representation of the actual production system. The architecture incorporates the Non-Dominated Sorting Genetic Algorithm-II optimization algorithm with a graph-based solution encoding and the production system environment, which adapts to specific production system requirements. An energy model parameter estimation module supports the automatic configuration of production machine energy models.

Evaluation of the proposed concepts in the ETA Research Factory demonstrates the system’s success in reducing energy consumption while maintaining production-related objectives. The energy-aware production scheduling system achieves average energy cost savings of 13 % and 18 % compared to traditional Shortest Processing Time dispatching rules while slightly improving or marginally decreasing production-related performance, respectively.

This thesis contributes to the field of energy-aware production scheduling by providing an implementation procedure and an adaptable architecture that fulfills the set requirements and success criteria. The proposed concepts offer practical solutions for adopting energy-aware production scheduling systems in industrial settings, promoting environmentally conscious and economically viable production practices. The thesis also identifies areas for improvement and future research, ensuring the continuous development of energy-efficient and sustainable manufacturing processes.
Central Limit theorems and Packing Problems in Dynamics and Geometry

description: The present thesis describes two applications of Busemann-like functions to problems in dynamics and geometry. Busemann-like functions are used in various fields of mathematics to describe the distance to a point at infinity, and generalize the concept of horofunction. They describe the large-scale geometry of geodesics in a Hadamard spaces, and have recently been successfully used to show probabilistic properties. The first application uses Busemann-like functions to derive a Central Limit Theorem (CLT) for matrix valued cocycles where the process is driven by a topological Markov chain. We state a CLT in the non-commutative setting of random matrix products where the underlying process is driven by a subshift of finite type (SFT) with Markov measure. For the proof we use the martingale method introduced by Y. Benoist and J.F. Quint in the iid setting. Busemann-like cocycles via an auxiliary boundary space let us extend a centered cocycle and apply Brown's Martingale CLT to obtain the result. The second application is a direct use of the Busemann function to a packing problems in hyperbolic geometry. We give new packing density lower bounds for horoball packings in hyperbolic 5-space $\mathbb{H}^5$, realized in eleven different configurations within Coxeter simplex tilings. They are described in terms of the Busemann function, a hyperbolic isometry invariant, and appear in a commensurability class of arithmetic Coxeter groups. The Busemann functions paramerize the type of the various horospheres relative to a marked point (origin) $o \in \mathbb{H}^5$. Varying this parameter allows continuous transitions between the extremal optimal packing configurations. The new packing density lower bound is given in terms of the Riemann zeta function to be $\frac{5}{7 \zeta(3)}$. We conjecture this is optimal.
