description: We combine the multigrid (MG) method with state-of-the-art concepts from the variational formulation of the numerical renormalization group. The resulting MG renormalization (MGR) method is a natural generalization of the MG method for solving partial differential equations. When the solution on a grid of $N$ points is sought, our MGR method has a computational cost scaling as $\mathcal{O}(\log(N))$, as opposed to $\mathcal{O}(N)$ for the best standard MG method. Therefore MGR can exponentially speed up standard MG computations. To illustrate our method, we develop a novel algorithm for the ground state computation of the nonlinear Schrödinger equation. Our algorithm acts variationally on tensor products and updates the tensors one after another by solving a local nonlinear optimization problem. We compare several different methods for the nonlinear tensor update and find that the Newton method is the most efficient as well as precise. The combination of MGR with our nonlinear ground state algorithm produces accurate results for the nonlinear Schrödinger equation on $N = 10^{18}$ grid points in three spatial dimensions.

description: The rate of data growth outpaces the decline of hardware costs, and there has been an ever-increasing demand in reducing the storage and network overhead for online database management systems (DBMSs). The most widely used approach for data reduction in DBMSs is blocklevel compression. Although this method is simple and effective, it fails to address redundancy across blocks and therefore leaves significant room for improvement for many applications. This dissertation proposes a systematic approach, termed similaritybased deduplication, which reduces the amount of data stored on disk and transmitted over the network beyond the benefits provided by traditional compression schemes. To demonstrate the approach, we designed and implemented dbDedup, a lightweight record-level similaritybased deduplication engine for online DBMSs. The design of dbDedup exploits key observations we find in database workloads, including small item sizes, temporal locality, and the incremental nature of record updates. The proposed approach differs from traditional chunk-based deduplication approaches in that, instead of finding identical chunks anywhere else in the data corpus, similarity-based deduplication identifies a single similar data-item and performs differential compression to remove the redundant parts for greater savings. To achieve high efficiency, dbDedup introduces novel encoding, caching and similarity selection techniques that significantly mitigate the deduplication overhead with minimal loss of compression ratio. For evaluation, we integrated dbDedup into the storage and replication components of a distributed NoSQL DBMS and analyzed its properties using four real datasets. Our results show that dbDedup achieves up to 37⇥ reduction in the storage size and replication traffic of the database on its own and up to 61⇥ reduction when paired with the DBMS’s block-level compression. dbDedup provides both benefits with negligible effect on DBMS throughput or client latency (average and tail).

description: Explicit relation between Laughlin state of the quantum Hall effect and one-dimensional(1D) model with long-ranged interaction ($1/r^2$) is discussed. By rewriting lowest Landau level wave functions in terms of 1D representation, Laughlin state can be written as a deformation of the ground state of Calogero-Sutherland model. Corresponding to Laughlin state on different geometries, different types of 1D $1/r^2$ interaction models are derived.

description: We investigate the phenomenology of scalar singlet dark matter candidates that couple dominantly to the Standard Model via a Yukawa interaction with the top quark and a colored vector-like fermion. We estimate the viability of this vector-like portal scenario with respect to the most recent bounds from dark matter direct and indirect detection, as well as to dark matter and vector-like mediator searches at colliders. Moreover, we take QCD radiative corrections into account in all our theoretical calculations. This work complements analyses related both to models featuring a scalar singlet coupled through a vector-like portal to light quarks, and to scenarios in which the dark matter is a Majorana singlet coupled to the Standard Model through scalar colored particles (akin to simplified models inspired by supersymmetry). Our study puts especially forward the complementarity of different search strategies from different contexts, and we show that current experiments allow for testing dark matter masses ranging up to 700 GeV and mediator masses ranging up to 6 TeV.

On-demand Isolated I/O for Security-sensitive Applications on Commodity Platforms

description: Today large software systems (i.e., giants) thrive in commodity markets, but are untrustworthy due to their numerous and inevitable software bugs that can be exploited by the adversary. Thus, the best hope of security is that some small, simple, and trustworthy software components (i.e., wimps) can be protected from attacks launched by adversary-controlled giants. However, wimps in isolation typically give up a variety of basic services (e.g., file system, networking, device I/O), trading usefulness and viability with security. Among these basic services, isolated I/O channels remained an unmet challenge over the past three decades. Isolated I/O is a critical security primitive for a myriad of applications (e.g., secure user interface, remote device control). With this primitive, isolated wimps can transfer I/O data to commodity peripheral devices and the data secrecy and authenticity are protected from the co-existing giants. This thesis addresses this challenge by proposing a new security architecture to provide services to isolated wimps. Instead of restructuring the giants or bloating the Trusted Computing Base that underpins wimp-giant isolation (dubbed underlying TCB), this thesis presents a unique on-demand I/O isolation model and a trusted add-on component called wimpy kernel to instantiate this model. In our model, the wimpy kernel dynamically takes control of the devices managed by a commodity OS, connects them to the isolated wimps, and relinquishes controls to the OS when done. This model creates ample opportunities for the wimpy kernel to outsource I/O subsystem functions to the untrusted OS and verify their results. The wimpy kernel further exports device drivers and I/O subsystem code to wimps and mediates the operations of the exported code. These two methodologies help to significantly reduce the size and complexity of the wimpy kernel for high security assurance. Using the popular and complex USB subsystem as a case study, this thesis illustrates the dramatic reduction of the wimpy kernel; i.e., over 99% of the Linux USB code base is removed. In addition, the wimpy kernel also composes with the underlying TCB, by retaining its code size, complexity and security properties.
Understanding the enablers and disablers of mainstreaming FAIR – the Case of CGIAR
Creators: name: CAB International
Publisher: name: Gates Open Research
Year: 2024

description: This case study examines the implementation of FAIR (Findable, Accessible, Interoperable, Reusable) data principles within CGIAR's Excellence in Agronomy Initiative (EiA). The study focuses on the challenges and successes encountered in promoting data sharing and compliance across CGIAR's centers.

The EiA aligns its strategies with CGIAR's FAIR and Open Data Assets Policy and donor expectations. However, obstacles such as diverse donor data policies and complexities within national systems impede universal FAIR adoption.

Despite efforts, FAIR compliance remains inconsistent across CGIAR's centers, revealing entrenched data silos and a lack of repercussions for non-compliance. Medha Devare underscores the necessity for more rigorous policies to catalyze a shift towards transparent data-sharing practices.

The study advocates for funders to play a proactive role by conditioning final funding on FAIR compliance and emphasizes the importance of promoting existing data management tools and resources. Collaboration among CGIAR, its partners, and funders is highlighted as essential for fostering a sustainable data-sharing ecosystem in agricultural research.

This case study serves as a valuable resource for organizations seeking to enhance data management practices and navigate challenges in mainstreaming FAIR principles within complex research environments.

description: We deal with the test of the general relativistic gravitomagnetic Lense-Thirring effect currently ongoing in the Earth's gravitational field with the combined nodes Ωof the laser-ranged geodetic satellites LAGEOS and LAGEOS II. One of the most important source of systematic uncertainty on the orbits of the LAGEOS satellites, with respect to the Lense-Thirring signature, is the bias due to the even zonal harmonic coefficients J_L of the multipolar expansion of the Earth's geopotential which account for the departures from sphericity of the terrestrial gravitational potential induced by the centrifugal effects of its diurnal rotation. The issue addressed here is: are the so far published evaluations of such a systematic error reliable and realistic? The answer is negative. Indeed, if the difference ΔJ_L among the even zonals estimated in different global solutions (EIGEN-GRACE02S, EIGEN-CG03C, GGM02S, GGM03S, ITG-Grace02, ITG-Grace03s, JEM01-RL03B, EGM2008, AIUB-GRACE01S) is assumed for the uncertainties δJ_L instead of using their more or less calibrated covariance sigmas σ_{J_L}, it turns out that the systematic error δμin the Lense-Thirring measurement is about 3 to 4 times larger than in the evaluations so far published based on the use of the sigmas of one model at a time separately, amounting up to 37% for the pair EIGEN-GRACE02S/ITG-Grace03s. The comparison among the other recent GRACE-based models yields bias as large as about 25-30%. The major discrepancies still occur for J_4, J_6 and J_8, which are just the zonals the combined LAGEOS/LAGOES II nodes are most sensitive to.

A stochastic asymptotic-preserving scheme for the bipolar semiconductor Boltzmann-Poisson system with random inputs and diffusive scalings

description: In this paper, we study the bipolar Boltzmann-Poisson model, both for the deterministic system and the system with uncertainties, with asymptotic behavior leading to the drift diffusion-Poisson system as the Knudsen number goes to zero. The random inputs can arise from collision kernels, doping profile and initial data. We adopt a generalized polynomial chaos approach based stochastic Galerkin (gPC-SG) method. Sensitivity analysis is conducted using hypocoercivity theory for both the analytical solution and the gPC solution for a simpler model that ignores the electric field, and it gives their convergence toward the global Maxwellian exponentially in time. A formal proof of the stochastic asymptotic-preserving (s-AP) property and a uniform spectral convergence with error exponentially decaying in time in the random space of the scheme is given. Numerical experiments are conducted to validate the accuracy, efficiency and asymptotic properties of the proposed method.

description: In language modeling, it is difficult to incorporate entity relationships from a knowledge-base. One solution is to use a reranker trained with global features, in which global features are derived from n-best lists. However, training such a reranker requires manually annotated n-best lists, which is expensive to obtain. We propose a method based on the contrastive estimation method that alleviates the need for such data. Experiments in the music domain demonstrate that global features, as well as features extracted from an external knowledge-base, can be incorporated into our reranker. Our final model, a simple ensemble of a language model and reranker, achieves a 0.44\% absolute word error rate improvement over an LSTM language model on the blind test data.

description: The function and performance of neural networks is largely determined by the evolution of their weights and biases in the process of training, starting from the initial configuration of these parameters to one of the local minima of the loss function. We perform the quantitative statistical characterization of the deviation of the weights of two-hidden-layer ReLU networks of various sizes trained via Stochastic Gradient Descent (SGD) from their initial random configuration. We compare the evolution of the distribution function of this deviation with the evolution of the loss during training. We observed that successful training via SGD leaves the network in the close neighborhood of the initial configuration of its weights. For each initial weight of a link we measured the distribution function of the deviation from this value after training and found how the moments of this distribution and its peak depend on the initial weight. We explored the evolution of these deviations during training and observed an abrupt increase within the overfitting region. This jump occurs simultaneously with a similarly abrupt increase recorded in the evolution of the loss function. Our results suggest that SGD's ability to efficiently find local minima is restricted to the vicinity of the random initial configuration of weights.

The results agree with the prediction of perturbation theory. A practical difficulty of the method for a reliable extraction of the phase shift for large momenta due to the necessity of a precise determination of excited two-particle energy levels is pointed out.

description: We argue that theories with fundamental fermions which undergo chiral symmetry breaking have several universal features which are qualitatively different than those of theories with fundamental scalars. Several bounds on the critical indices $δ$ and $η$ follow. We observe that in four dimensions the logarithmic scaling violations enter into the Equation of State of scalar theories, such as $λϕ^4$, and fermionic models, such as Nambu-Jona-Lasinio, in qualitatively different ways. These observations lead to useful approaches for analyzing lattice simulations of a wide class of model field theories. Our results imply that $λϕ^4$ {\it cannot} be a good guide to understanding the possible triviality of spinor $QED$.

description: The spin-1/2 square-lattice Heisenberg model is predicted to have a quantum disordered ground state when magnetic frustration is maximized by competing nearest-neighbor $J_1$ and next-nearest-neighbor $J_2$ interactions ($J_2/J_1 \approx 0.5$). The double perovskites Sr$_2$CuTeO$_6$ and Sr$_2$CuWO$_6$ are isostructural spin-1/2 square-lattice antiferromagnets with Néel ($J_1$ dominates) and columnar ($J_2$ dominates) magnetic order, respectively. Here we characterize the full isostructural solid solution series Sr$_2$Cu(Te$_{1-x}$W$_x$)O$_6$ ($0 \leq x \leq 1$) tunable from Néel order to quantum disorder to columnar order. A spin-liquid-like ground state was previously observed for the $x$ = 0.5 phase, but we show that the magnetic order is suppressed below 1.5 K in a much wider region of $x \approx$ 0.1-0.6. This coincides with significant $T$-linear terms in the low-temperature specific heat. However, density functional theory calculations predict most of the materials are not in the highly frustrated $J_2/J_1 \approx 0.5$ region square-lattice Heisenberg model. Thus, a combination of both magnetic frustration and quenched disorder is the likely origin of the spin-liquid-like state in $x$ = 0.5.

description: The interplay of spin-orbit coupling and Zeeman splitting in ultracold Fermi gases gives rise to a topological superfluid phase in two spatial dimensions that can host exotic Majorana excitations. Theoretical models have so far been based on a four-band Bogoliubov-de Gennes formalism for the combined spin-1/2 and particle-hole degrees of freedom. Here we present a simpler, yet accurate, two-band description based on a well-controlled projection technique that provides a new platform for exploring analogies with chiral p-wave superfluidity and detailed future studies of spatially non-uniform situations.

description: We report on the discovery of the z=1.016 cluster RzCS 052 using a modified red sequence method, followup spectroscopy and X-ray imaging. This cluster has a velocity dispersion of 710+-150 km/s, a virial mass of 4.0e14 Msol (based on 21 spectroscopically confirmed members) and an X-ray luminosity of (0.68+- 0.47)e44 ergs/s in the [1-4] keV band. This optically selected cluster appears to be of richness class 3 and to follow the known L_X-sigma_v relation for high redshift X-ray selected clusters. Using these data, we find that the halo occupation number for this cluster is only marginally consistent with what expected assuming a self-similar evolution of cluster scaling relations, suggesting perhaps a break of them at z~1. We also rule out a strong galaxy merging activity between z=1 and today. Finally, we present a Bayesian approach to measuring cluster velocity dispersions and X-ray luminosities in the presence of a background: we critically reanalyze recent claims for X-ray underluminous clusters using these techniques and find that the clusters can be accommodated within the existing L_X -sigma_v relation.

description: Chemotherapeutic response of cancer cells to a given compound is one of the most fundamental information one requires to design anti-cancer drugs. Recent advances in producing large drug screens against cancer cell lines provided an opportunity to apply machine learning methods for this purpose. In addition to cytotoxicity databases, considerable amount of drug-induced gene expression data has also become publicly available. Following this, several methods that exploit omics data were proposed to predict drug activity on cancer cells. However, due to the complexity of cancer drug mechanisms, none of the existing methods are perfect. One possible direction, therefore, is to combine the strengths of both the methods and the databases for improved performance. We demonstrate that integrating a large number of predictions by the proposed method improves the performance for this task. The predictors in the ensemble differ in several aspects such as the method itself, the number of tasks method considers (multi-task vs. single-task) and the subset of data considered (sub-sampling). We show that all these different aspects contribute to the success of the final ensemble. In addition, we attempt to use the drug screen data together with two novel signatures produced from the drug-induced gene expression profiles of cancer cell lines.

Threshold Effects and the Line Shape of the X(3872) in Effective Field Theory

Year: 2018
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Latest measurements suggest that the X(3872) mass lies less than 200 keV away from the D0-Dbar0* threshold, reenforcing its interpretation as a loosely-bound mesonic molecule. This observation implies that in processes like D0-Dbar0-pi0 production, threshold effects could disguise the actual pole position of the X(3872). We propose a new effective field theory with D0, Dbar0 and pi0 degrees of freedom for the X(3872), considering Galilean invariance to be an exact symmetry. The D0* enters as a D0-pi0 p-wave resonance, allowing for a comprehensive study of the influence of pion interactions on the X(3872) width. We calculate relations between the mass of the X(3872), its width, and its line shape in D0-Dbar0-pi0 production up to next-to-leading order. Our results provide a tool for the extraction of the X(3872) pole position from the experimental data near threshold.

API

description: The Beta launch of Jisc's Romeo Service is a significant milestone towards the completion of the v2.Sherpa project. Our services now all share the same platform, user interface, data model and API. The API is lightweight, RESTful and returns UFT-8 JSON. It supports the export of all first class object types contained in the system, namely Publishers, Publisher Policies, Publications, Repositories (with attached policies), and Funders (with attached policies). These can be exported in paged, filtered collections. We would like to give a live demonstration of the v2.Sherpa API to the dev track, invite the attendees to informally have a go, and have a brief discussion focused around further user requirements and use-cases (to be continued outside of the track).
Reconstructing large scales at cosmic dawn

description: The cosmic microwave background (CMB) serves as a backlight to large-scale structure during the epoch of reionization, where Thomson scattering gives rise to temperature anisotropies on small angular scales from the kinetic Sunyaev Zel'dovich (kSZ) effect. In this paper, we demonstrate that the technique of kSZ tomography (velocity reconstruction), based on cross correlations between CMB temperature and 21cm surveys, can significantly improve constraints on models of inhomogeneous reionization and provide information about large-scale modes that are poorly characterized by 21cm measurements themselves due to foreground contamination.

description: Astronomy has entered the big data era and Machine Learning based methods have found widespread use in a large variety of astronomical applications. This is demonstrated by the recent huge increase in the number of publications making use of this new approach. The usage of machine learning methods, however is still far from trivial and many problems still need to be solved. Using the evaluation of photometric redshifts as a case study, we outline the main problems and some ongoing efforts to solve them.

description: This session will discuss the Music Row Experience Project (MREP) which is creating new user experiences via open source software. Funded by the National Archives, MREP seeks to increase collections engagement by connecting repositories to game-like app and web-based interactive experiences. This session will discuss how we can improve current digital information access and delivery methods, and reward user engagement similar to social media and alert responses from video games. The session will cover the open source software the project is using and user interface development. By making the collections' content portable and social, and by creating an interactive, game-like environment, MREP will deliver content to people where they are, in a setting where they frequently spend time. Individuals across generations are interacting with digital devices and content. This session will discuss how we can transition from relying on traditional research methods and repositories, to delivering users access to the content in the spaces they prefer.
The Phase Diagram of the $N=2$ Kazakov-Migdal Model

description: We have determined the phase diagram of the simplest version of a lattice model introduced in the recent work of Kazakov and Migdal. If $m_0$ and $λ$ are the bare mass and self coupling of the scalar field in the model respectively, we find a line of first order phase transitions in the ($m_0, λ$) plane ending in a critical point where $λ$ is nonzero. Kazakov and Migdal speculate that their model of scalar field theory could induce QCD. Our work indicates that for $N=2$ there is no continuum limit for the Kazakov-Migdal model except at the critical end point. Whether or not a nontrivial continuum limit exists in the vicinity of the critical point requires careful study of the renormalization group properties of the model.

A neural network memory prefetcher using semantic locality

description: Accurate memory prefetching is paramount for processor performance, and modern processors employ various techniques to identify and prefetch different memory access patterns. While most modern prefetchers target spatio-temporal patterns by matching memory addresses that are accessed in close proximity (either in space or time), the recently proposed concept of semantic locality views locality as an artifact of the algorithmic level and searches for correlations between memory accesses and program state. While this approach was shown to be effective, capturing semantic locality requires significant associative learning capabilities. In this paper we utilize neural networks for this task. We leverage recent advances in machine learning to propose a neural network prefetcher. We show that by observing program context, this prefetcher can learn distinct memory access patterns that cannot be covered by other state-of-the-art prefetchers. We evaluate the neural network prefetcher over SPEC2006, Graph500, and several microbenchmarks. We show that the prefetcher can deliver an average speedup of 30% for SPEC2006 (up to 2.7x) and up to 4.6x over kernels. We also present a high-level design of our prefetcher, explore the power, energy and area limitations, and propose several optimizations for feasibility. We believe that this line of research can further improve the efficiency of such neural networks and allow harnessing them for additional micro-architectural predictions.

On the Plastic Collapse of Structures and Linear Programming
Creators: name: Dorn, William S.
Publisher: name: Carnegie Mellon University
Year: 1955
Subjects: subject: 19999 Mathematical Sciences not elsewhere classified
subject: FOS: Mathematics

description: This paper is concerned with the solution of various problems in the plastic collapse of plane structures. In Chapter I the basic problems and theorems of limit analysis are reviewed and formulated in a convenient notation. A pair of superposition principles are developed for limit analysis of structures in Chapter II. These principles lead to upper and lower bounds to the safety factor for a superimposed load system in terms of bounds to the safety factors for the individual loads. In addition several special problems are posed and solved in the second chapter. These include a minimax problem in which a safety factor which is valid for all load systems in a given range is found. Finally an iterative method is given for obtaining bounds to the safety factor for the proportional loading of frames when axial forces as well as bending moments are to be considered. Examples are included at the end of the chapter. Chapter III reviews three basic methods of solution for linear programming problems. The problem of the plastic collapse of structures is reduced to forms suitable for the application of these three methods. A collapse problem is solved by the several linear programming methods in Chapter IV for demonstration and comparison. A method for obtaining an initial feasible solution for Lemke's dual method of solving the linear programming problem is given in Appendix C. This method is analogous to a procedure developed by Dantzig for the simplex method.

repository redesign

description: Since starting as the Open Access and Research Repository Specialist in March 2018, I have undertaken a comprehensive review on the Open Access (OA) processes in place at Aston University. The aim of this project was two-fold: the immediate enhancement of service levels and the implementation of workflows and technical improvements to increase the visibility and usability of Aston Publications Explorer, our institutional publications repository. There were multiple challenges along the way, including: entrenched behaviours by Library staff and academics, Pure-Eprints interoperability, external support limitations, and knowledge gaps– not to mention the pressures of REF 2021 and an eventful time in Open Access policy across Europe. Despite these challenges, we have made a great deal of progress in the past year. Key milestones include ORCiD integration, Core Recommender integration, better Google/ Google Scholar indexing, a new repository policy, and an improved user interface in both the publications and data repositories. While most of these changes have been more 'tweak' than 'major overhaul', all of them have contributed to a better user experience and greatly improved the visibility and discoverability of the content in our repositories and show that even little changes can have a big impact on repository users.
An elementary construction of Anick's fibration

description: Cohen, Moore, and Neisendorfer's work on the odd primary homotopy theory of spheres and Moore spaces, as well as the first author's work on the secondary suspension, predicted the existence of a p-local fibration S^2n-1 --> T --> ΩS^2n+1 whose connecting map is degree p^r. In a long and complex monograph, Anick constructed such a fibration for p>= 5 and r>= 1. Using new methods we give a much more conceptual construction which is also valid for p=3 and r>= 1. We go on to establish several properties of the space T.
