Cancer pathways are deranged in Mucopolysaccharidoses
Creators: name: Villalba, Gerda Cristal Villalba

Publisher: name: F1000 Research Limited
Year: 2020

description: Defects in activity of lysosomal hydrolases involved in glycosaminoglycan degradation lead to a group of lysosomal storage diseases called Mucopolysaccharidosis (MPS). In MPS, secondary cell disturbance affects pathways common to cancer. This work aims to investigate the differential expression of cancer pathways in MPS datasets available in public functional genomics data repository, such as GEO (Gene Expression Omnibus) and ArrayExpress. We performed Gene Ontology analysis with QuickGo and KEGG annotations, and the network was constructed with ShinyGo (v0.61) based on hypergeometric distribution followed by FDR correction. We selected 12 datasets, being 2 of MPS I; 1 from MPS II; 1 from MPS IIIA; 3 MPS IIIB; 1 MPS VI; and 4 from MPS VII. The most abundant ontologies found were PI3K−Akt signaling pathway; MAPK signaling pathway; Ras signaling pathway; Rap1 signaling pathway and cAMP signaling pathway. We hypothesize that these signaling pathways are altered because glycosaminoglycans play an essential role in the composition of the extracellular matrix, helping to regulate processes such as metabolic signaling, apoptosis, cell migration, adhesion, and antigen presentation. Understanding these biological processes may help us look for new biomarkers for these rare metabolic diseases.

description: We report the results of a new experimental search for a permanent electric dipole moment of 199Hg utilizing a stack of four vapor cells. We find d(199Hg) = (0.49 \pm 1.29_stat \pm 0.76_syst) x 10^{-29} e cm, and interpret this as a new upper bound, |d(199Hg)| < 3.1 x 10^{-29} e cm (95% C.L.). This result improves our previous 199Hg limit by a factor of 7, and can be used to set new constraints on CP violation in physics beyond the standard model.

Evaluating the role of mixed frequency real-time weather data in economic forecasts
Creators: name: Goodwin, TK
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis examines the role of weather forecasts in economic decision making and proposes a state-space model for evaluating multi-horizon forecasts. Our first application sets the scene by using mixed frequency real-time weather data to improve the predictive performance of retail sales forecasts. Our findings illustrate that significant improvements in predictive accuracy can be achieved when weather variables are incorporated into a mixed frequency forecasting model. However, once we move to a real-time environment, substituting meteorological forecasts for observed weather variables, meteorological forecast uncertainty leads to a somewhat muted improvement in predictive accuracy. The implication is that real-time data constraints are a limitation of forecasting models that use weather variables as an input. This points to a role for forecast evaluation and the need to better understand the structure of forecasting error. Our state-space model of multi-horizon forecasts is based on the forecast revision structure implied by forecast rationality. The parameters of this model allow us to identify rational forecast revision components, that we call information content, as well as residual forecasting error components, that we call implicit forecasting error. A key contribution of this thesis is the demonstration of how our model based approach to forecast evaluation nests existing test based approaches as special cases. We illustrate our proposed multi-horizon forecast evaluation approach using two empirical applications. First, we employ our model based approach to examine the structure of forecasting error in multi-horizon meteorological forecasts of daily temperature. Multi-horizon temperature forecasts are found to contain multiple sources of forecasting error. The structure of meteorological forecasting error depends on the length of the forecast horizon. Second, we employ our model to examine the information content of multi-horizon electricity demand forecasts for the New South Wales region of the Australian National Electricity Market. We discover that the information content of electricity demand forecasts depends not only on the length of the horizon at which the forecasts are made, but also the time of day the forecasts are made.

description: Gravitino dark matter, together with thermal leptogenesis, implies an upper bound on the masses of superparticles. In the case of broken R-parity the constraints from primordial nucleosynthesis are naturally satisfied and decaying gravitinos lead to characteristic signatures in high energy cosmic rays. Electron and positron fluxes from gravitino decays cannot explain both, the PAMELA positron fraction and the electron + positron flux recently measured by Fermi LAT. The observed fluxes require astrophysical sources. The measured antiproton flux allows for a sizable contribution of decaying gravitinos to the gamma-ray spectrum, in particular a line at an energy below 300 GeV.

description: The Local Density Approximation combined with Dynamical Mean-Field Theory (LDA+DMFT method) is applied to the study of the paramagnetic and magnetically ordered phases of hematite Fe$_2$O$_3$ as a function of volume. As the volume is decreased, a simultaneous 1st order insulator-metal and high-spin to low-spin transition occurs close to the experimental value of the critical volume. The high-spin insulating phase is destroyed by a progressive reduction of the charge gap with increasing pressure, upon closing of which the high spin phase becomes unstable. We conclude that the transition in Fe$_2$O$_3$ at $\approx$50 GPa can be described as an electronically driven volume collapse.

description: The science of networks, a relatively young field of research that appeared in such a form and definition at the beginning of the 21st century (as a distinctive, officially approved and accepted scientific discipline (Barabási, 2016)), represents a very powerful area considering the range of subjects to which it contributes and is applied. This science is key for complex systems analysis or analytics (when referring to the (big) data science framework, which now mostly defines its methods and resources (Betty, 2019)) based on the claim that (Barabási, 2016) and thus provide insights into the ways complex systems behave, or control the behaviour of the artificially created systems (emphasis added). The area represented here, through its analytical methods and forms (network graphs and related operations), is the urban transportation system the Grand Paris rail system, including all the categories with their existing lines and extensions currently either in construction and planned, or under consideration in the long term. The network has been created as a background topological environment and geometry for various research operations and generative design tasks. Some of them, such as urban movement path generation or the network's incremental growth and reconfiguration as a system and geometry of possible moves ("legal actions"), will be presented in more detail. The network can be considered both an abstract and real-world environment and situation, susceptible to the research of both gaming strategies for any constructed scenario and designed spatial situation (academic gaming, operational gaming, and heuristic gaming) and problem-solving strategies related to identified real-world design issues. Thus, the main question addresses the ways in which its presented graph can be operationalised and the methods through which this can be achieved, with special regard to AI.

description: We investigate the magnetic penetration depth λin superconducting Ba_1-xK_xFe_2As_2 (T_c\simeq32K) with muon-spin rotation (\muSR) and angle-resolved photoemission (ARPES). Using \muSR, we find the penetration-depth anisotropy γ_λ=λ_c/λ_{ab} and the second-critical-field anisotropy γ_{H_c2} to show an opposite T-evolution below T_c. This dichotomy resembles the situation in the two-gap superconductor MgB_2. A two-gap scenario is also suggested by an inflection point in the in-plane penetration depth λ_ab around 7K. The complementarity of \muSR and ARPES allows us to pinpoint the values of the two gaps and to arrive to a remarkable agreement between the two techniques concerning the full T-evolution of λ_ab. This provides further support for the described scenario and establishes ARPES as a tool to assess macroscopic properties of the superconducting condensate.

This system is designed to generate an electric power output of 500 kW from a heat source maintained at 500℃. The main components of the system include a compressor with a driving turbine, a recuperator, a power turbine, and a waste heat recovery heat exchanger. For each component, a test rig is prepared except for the power turbine. The components are tested for their performance and reliability. The power turbine has a unique double suction design and its performance is estimated only by computational fluid dynamics. The target efficiency of the compressor and the power turbine at the power output of 500kW were 80% and 85%, respectively, and the test results showed 83.7% and 92.6% for each component, well beyond the target efficiency.

Federalism, Private Rights, and Article III Adjudication
Creators: name: Golden, John M.

Publisher: name: University of Notre Dame
Year: 2023

description: This Article sheds new light on the private rights/public rights distinction used by the Supreme Court to assess the extent to which the United States Constitution permits adjudication by a non-Article III federal tribunal. State courts have traditionally been the primary deciders of lawsuits over private rights—historically defined as suits regarding “the liability of one individual to another under the law as defined.” If Congress could limitlessly assign adjudication of private rights cases to federal officials lacking the life tenure and salary protections of Article III judges, the political branches of the federal government would enjoy vastly expanded authority to encroach on state courts’ traditional authority to decide common-law and equity cases between individuals. We argue that such vast congressional power is inconsistent with the limits on federal authority in a constitutional scheme in which state courts have traditionally dominated the adjudication of ordinary private disputes and in which Congress’s power of direct taxation and ability to create lower federal courts were hard-won concessions. Article III’s implicit constraints on congressional power to confer private rights cases on non-Article III federal tribunals effectively checks federal power to supplant state-court adjudication by requiring that adjudicative power over such cases go substantially to Article III courts, bodies constitutionally insulated from congressional control. The private rights/public rights distinction thus operationalizes a principle of constitutional federalism through the mechanism of federal-level separation of powers. Article III’s federalism underlay explains the Supreme Court’s special concern with non-Article III adjudication of state-law claims and of questions of “jurisdictional” fact—two doctrinal positions that have puzzled commentators focused on the threat that proliferation of non-Article III tribunals poses to the power of Article III courts, rather than to the power of state courts and local juries. By showing how federalism is an important part of the non-Article III adjudication puzzle, this Article complements prior accounts that focus solely on concerns with the separation powers and individual liberty.

description: In this work we launch a systematic theory of superconformal blocks for four-point functions of arbitrary supermultiplets. Our results apply to a large class of superconformal field theories including 4-dimensional models with any number $\mathcal{N}$ of supersymmetries. The central new ingredient is a universal construction of the relevant Casimir differential equations. In order to find these equations, we model superconformal blocks as functions on the supergroup and pick a distinguished set of coordinates. The latter are chosen so that the superconformal Casimir operator can be written as a perturbation of the Casimir operator for spinning bosonic blocks by a fermionic (nilpotent) term. Solutions to the associated eigenvalue problem can be obtained through a quantum mechanical perturbation theory that truncates at some finite order so that all results are exact. We illustrate the general theory at the example of $d=1$ dimensional theories with $\mathcal{N}=2$ supersymmetry for which we recover known superblocks. The paper concludes with an outlook to 4-dimensional blocks with $\mathcal{N}=1$ supersymmetry.
Static input-output tables : an evaluation of their efficiency as a forecasting tool in the West Malaysian case
Creators: name: Hodgins, Barbara Louise
Publisher: name: University of British Columbia
Year: 2011

description: A series of six consecutive input-output tables has been constructed for the economy of West Malaysia for the period from 1960 to 1965. This thesis provides an evaluation of their efficiency when applied in forecasting intermediate output. A brief review of the theoretical structure of the static input-output model developed by Leontief has been presented. Particular attention has been given to the economic assumptions which are necessary to make the prediction procedure tenable. The basic assumption of constant input coefficients was not tested directly, however. Instead, the empirical usefulness of the input-output system has been evaluated in terms of the quality of predictions it yields. Each of the tables from 1960 to 1964 has been used in turn to predict intermediate sectoral outputs for succeeding years to 1965. Input-output prediction errors were calculated by reference to the observed intermediate outputs set forth in the tables. To test the significance of these errors, a comparison was made with the errors that arose when corresponding projections of intermediate output were made from a naive extrapolation model. In addition the overall effect on the input-output predictions of the length of the forecast period was analyzed and the relative performance of individual sectors was examined. Wherever possible, the efficiency of the West Malaysian tables was compared with that of input-output tables for the Netherlands economy. In general the predictive power of the West Malaysian tables was not impressive. On the average the input-output forecasts proved to be superior to the naive extrapolations only when the prediction period did not exceed two years. For individual sectoral forecasts, the input-output model yielded better predictions of intermediate output in only seven of the 15 sectors considered. In every comparison with the efficiency of the Netherlands tables, the inferiority of the West Malaysian tables was demonstrated. Attempts have been made in the thesis to trace the reasons for the poor performance. Some improvements to the tables have been suggested.

description: In 2020, the Securities and Exchange Commission revised human capital disclosure rules to improve shareholder understanding of how human capital management contributes to corporate value and strategy. In this Closer Look, we examine early disclosure choices that companies have made under these rules to evaluate the information they share about employment practices. We find that while some companies are transparent in explaining the philosophy, design, and focus of their HCM, most disclosure is boilerplate and lacks quantitative metrics. As such, the new rules appear to contribute to the length but not the informativeness of 10-K disclosure. We ask: Are companies being evasive, or are they in the early stages of determining what information is relevant to the market? Will market pressure lead to better disclosure over time? Can a company provide informative disclosure without providing concrete metrics? Is there a way to describe comprehensive HCM efforts in concise and informative language, supplemented with data, in a manner that does not reveal proprietary practices?

description: Multi-terminal Aharonov-Bohm (AB) rings are ideal building blocks for quantum networks (QNs) thanks to their ability to map input states into controlled coherent superpositions of output states. We report on experiments performed on three-terminal GaAs/Al_(x)Ga_(1-x)As AB devices and compare our results with a scattering-matrix model including Lorentz forces and decoherence. Our devices were studied as a function of external magnetic field (B) and gate voltage at temperatures down to 350 mK. The total output current from two terminals while applying a small bias to the third lead was found to be symmetric with respect to B with AB oscillations showing abrupt phase jumps between 0 and pi at different values of gate voltage and at low magnetic fields, reminiscent of the phase-rigidity constraint due to Onsager-Casimir relations. Individual outputs show quasi-linear dependence of the oscillation phase on the external electric field. We emphasize that a simple scattering-matrix approach can not model the observed behavior and propose an improved description that can fully describe the observed phenomena. Furthermore, we shall show that our model can be successfully exploited to determine the range of experimental parameters that guarantee a minimum oscillation visibility, given the geometry and coherence length of a QN.

The analysis is carried out within a flavour-breaking expansion which encodes the effects of breaking the quark masses and electromagnetic charges away from an approximate SU(3) symmetric point. The results display total isospin splittings within the approximate SU(2) multiplets that are compatible with phenomenological estimates. Further, new insight is gained into these splittings by separating the contributions arising from strong and electromagnetic effects. We also present an update of earlier results on the octet baryon spectrum.

description: Quantum control requires full knowledge of the system many-body Hamiltonian. In many cases this information is not directly available due to restricted access to the system. Here we show how to indirectly estimate all the coupling strengths in a spin chain by measuring one spin at the end of the chain. We also discuss the efficiency of this "quantum inverse problem" and give a numerical example.

Molecular architectures based on pi-conjugated block copolymers for global quantum computation

description: We propose a molecular setup for the physical implementation of a barrier global quantum computation scheme based on the electron-doped pi-conjugated copolymer architecture of nine blocks PPP-PDA-PPP-PA-(CCH-acene)-PA-PPP-PDA-PPP (where each block is an oligomer). The physical carriers of information are electrons coupled through the Coulomb interaction, and the building block of the computing architecture is composed by three adjacent qubit systems in a quasi-linear arrangement, each of them allowing qubit storage, but with the central qubit exhibiting a third accessible state of electronic energy far away from that of the qubits' transition energy. The third state is reached from one of the computational states by means of an on-resonance coherent laser field, and acts as a barrier mechanism for the direct control of qubit entanglement. Initial estimations of the spontaneous emission decay rates associated to the energy level structure allow us to compute a damping rate of order 10^{-7} s, which suggest a not so strong coupling to the environment. Our results offer an all-optical, scalable, proposal for global quantum computing based on semiconducting pi-conjugated polymers.

title: Stock-Option Financing in Pre-IPO Companies

Publisher: name: Corporate Governance Research Initiative
Year: 2021

description: In this Closer Look, we examine a new industry that has arisen in recent years to facilitate the financing of stock-option exercises for employees and executives of pre-IPO companies. These capital providers allow individuals to exercise and retain their stock option awards, meaning the employee can continue to participate in any future appreciation of the shares while still receiving the money needed to exercise the award, pay taxes, and in some cases extract additional capital to finance personal expenditures. We consider the economic implications of this market from the perspectives of employees and employers, as well as the financial model of the capital providers that participate in this space. We ask: For which employees does stock-option financing make sense? Is the growth of this industry driven by large increases in private company valuations, or would it continue in the absence of these forces? Why haven’t more traditional lenders entered the market? Would more competition drive down lending rates and the returns these vendors enjoy? What impact does early exercise of stock options have on incentive programs?

The possibility of measuring intrinsic electronic correlations in graphene using a d-wave contact Josephson junction

description: While not widely recognized, electronic correlations might play an important role in graphene. Indeed, Pauling's resonance valence bond (RVB) theory for the pp-bonded planar organic molecules, of which graphene is the infinite extension, already established the importance of the nearest neighbor spin-singlet bond (SB) state in these materials. However, despite the recent growth of interest in graphene, there is still no quantitative estimate of the effects of Coulomb repulsion in either undoped or doped graphene. Here we use a tight-binding Bogoliubov-de Gennes (TB BdG) formalism to show that in unconventional d-wave contact graphene Josephson junctions the intrinsic SB correlations are strongly enhanced. We show on a striking effect of the SB correlations in both proximity effect and Josephson current as well as establishing a 1/(T-T_c) functional dependence for the superconducting decay length. Here T_c is the superconducting transition temperature for the intrinsic SB correlations, which depends on both the effects of Coulomb repulsion and the doping level. We therefore propose that d-wave contact graphene Josephson junctions will provide a promising experimental system for the measurement of the effective strength of intrinsic SB correlations in graphene.

description: We develop a combinatorial approach to the quantum permutation algebras, as Hopf images of representations of type $π:A_s(n)\to B(H)$. We discuss several general problems, including the commutativity and cocommutativity ones, the existence of tensor product or free wreath product decompositions, and the Tannakian aspects of the construction. The main motivation comes from the quantum invariants of the complex Hadamard matrices: we show here that, under suitable regularity assumptions, the computations can be performed up to $n=6$.
