description: We propose a general method for optimally approximating an arbitrary matrix $\mathbf{M}$ by a structured matrix $\mathbf{T}$ (circulant, Toeplitz/Hankel, etc.) and examine its use for estimating the spectra of genomic linkage disequilibrium matrices. This application is prototypical of a variety of genomic and proteomic problems that demand robustness to incomplete biosequence information. We perform a simulation study and corroborative test of our method using real genomic data from the Mouse Genome Database. The results confirm the predicted utility of the method and provide strong evidence of its potential value to a wide range of bioinformatics applications. Our optimal general matrix approximation method is expected to be of independent interest to an even broader range of applications in applied mathematics and engineering.

description: This demonstration deliverable concerns the integration of the Similarity Engine (as described in the deliverable D4.2) in the Generic Application Framework (GAF). The Similarity Engine implements a set of methods to measure the similarity between dance performances modeled using different data formats. The Similarity Engine is a fundamental block for several applications developed within the project. For this reason, the consortium decided to adopt a client-server architecture and provide the Engine as an Internet service. We provided an extensive description of the Similarity Engine in Deliverable D4.2. Whereas, we provide an exhaustive description of the integration policy in order to build the Generic Application Framework in Deliverable D4.3. In section 0 of this document we will give a brief overview of the integration of the Similarity Engine into the GAF such as described in D4.3. We prove the effectiveness of the GAF and the application integration procedure on use cases involving real performances. We will describe the performances in section 3.

description: Current and future accelerator neutrino oscillation experiments require an improved understanding of nuclear effects in neutrino-nucleus interactions. One important systematic uncertainty is introduced by the collective impact of nuclear effects which bias the reconstruction of the neutrino energy, such as the nuclear removal energy. In this manuscript, we introduce a novel observable for accelerator neutrino oscillation experiments, the visible longitudinal momentum imbalance, reconstructed in charged current quasi-elastic interactions from the outgoing charged lepton and nucleon. We demonstrate it to be minimally dependent on the neutrino energy and sensitive to sources of bias in neutrino energy reconstruction. Furthermore, we show how the use of the longitudinal imbalance in antineutrino interactions in a target containing hydrogen allows for an improved, high-purity selection of the interactions on hydrogen. This approach offers the potential for precise measurements of the nuclear axial vector form factor as well as of the antineutrino flux.

Using Video Games to Support Pre-Service Elementary Teachers Learning of Basic Physics Principles

description: The purpose of this work is to share our findings in using video gaming technology to facilitate the understanding of basic electromagnetism with preservice elementary teachers. To this end we explored the impact of using a game called Supercharged! on pre-service teachers’ understanding of electromagnetic concepts compared to students who conducted a more traditional inquiry oriented investigation of the same concepts. This study was a part of a larger design experiment examining the pedagogical potential of Supercharged! The control group learned through a series of guided inquiry methods while the experimental group played Supercharged! during the laboratory sections of the science course. There was significant difference F(2,134) = 4.8, p < 0.05, η2=0.59 between the control and experimental groups on the gains from pre-to-post assessment with an effect size of d = 0.72. However, while students in the experimental group performed better than their control group peers, they rated their knowledge of the topic lower than the control group (Mpost-control = 3.0, Mpost-experiment = 2.7), leading to further examination of their laboratory journals. Results of this study show that video games can lead to positive learning outcomes, as demonstrated by the increase in test scores from pre- to post-assessment. Additionally, this study also suggests that a complementary approach, in which video games and hands-on activities are integrated, with each activity informing the other, could be a very powerful technique for supporting student scientific understanding. Further, our findings suggest that video game designers should embed meta-cognitive activities such as reflective opportunities into educational video games to provide scaffolds for students and to reinforce that they are engaged in an educational learning experience.

description: Recent studies reported complex post-transcriptional interplay among targets of a common pool of microRNAs, a class of small non-coding downregulators of gene expression. Behaving as microRNA-sponges, distinct RNA species may compete for binding to microRNAs and coregulate each other in a dose-dependent manner. Although previous studies in cell populations showed competition in vitro, the detailed dynamical aspects of this process, most importantly in physiological conditions, remains unclear. We address this point by monitoring protein expression of two targets of a common miRNA with quantitative single-cell measurements. In agreement with a detailed stochastic model of molecular titration, we observed that: (i) crosstalk between targets is possible only in particular stoichiometric conditions, (ii) a trade-off on the number of microRNA regulatory elements may induce the coexistence of two distinct cell populations, (iii) strong inter-targets correlations can be observed. This phenomenology is compatible with a small amount of mRNA target molecules per cell of the order of 10-100.

description: We analyze a quantized pumping in a nonlinear non-Hermitian photonic system with nonadiabatic driving. The photonic system is made of a waveguide array, where the distances between adjacent waveguides are modulated. It is described by the Su-Schrieffer-Heeger model together with a saturated nonlinear gain term and a linear loss term. A topological interface state between the topological and trivial phases is stabilized by the combination of a saturated nonlinear gain term and a linear loss term. We study the pumping of the topological interface state. We define the transfer-speed ratio $ω/Ω$ by the ratio of the pumping speed $% ω$ of the center of mass of the wave packet to the driving speed $ Ω$ of the topological interface. It is quantized as $ω/Ω=1$ in the adiabatic limit. It remains to be quantized for slow driving even in the nonadiabatic regime, which is a nonadiabatic quantized pump. On the other hand, there is almost no pump for fast driving. We find a transition in pumping as a function of the driving speed.

Year: 2023

subject: FOS: Computer and information sciences

description: Conflict-free Replicated Data Types (CRDTs) allow optimistic replication in a principled way. Different replicas can proceed independently, being available even under network partitions, and always converging deterministically: replicas that have received the same updates will have equivalent state, even if received in different orders. After a historical tour of the evolution from sequential data types to CRDTs, we present in detail the two main approaches to CRDTs, operation-based and state-based, including two important variations, the pure operation-based and the delta-state based. Intended as a tutorial for prospective CRDT researchers and designers, it provides solid coverage of the essential concepts, clarifying some misconceptions which frequently occur, but also presents some novel insights gained from considerable experience in designing both specific CRDTs and approaches to CRDTs.

description: In this study we model early times dynamics of the system produced in relativistic heavy ion collisions by an initial color electric field which then decays to a plasma by the Schwinger mechanism, coupling the dynamical evolution of the initial color field to the dynamics of the many particles system produced by the decay. The latter is described by relativistic kinetic theory in which we fix the ratio $η/s$ rather than insisting on specific microscopic processes. We study isotropization and thermalization of the system produced by the field decay for a static box and for a $1+1$D expanding geometry. We find that regardless of the viscosity of the produced plasma, the initial color electric field decays within $1$ fm/c; however in the case $η/s$ is large, oscillations of the field are effective along all the entire time evolution of the system, which affect the late times evolution of the ratio between longitudinal and transverse pressure. In case of small $η/s$ ($η/s\lesssim0.3$) we find $τ_{isotropization}\approx 0.8$ fm/c and $τ_{thermalization}\approx 1$ fm/c in agreement with the common lore of hydrodynamics. Moreover we have investigated the effect of turning from the relaxation time approximation to the Chapman-Enskog one: we find that this improvement affects mainly the early times evolution of the physical quantities, the effect being milder in the late times evolution.

description: We make an attempt to describe Carroll particles with a non-vanishing value of energy (i.e. the Carroll particles which always stay in rest) in the framework of two time physics, developed in the series of papers by I. Bars and his co-authors. In the spacetime with one additional time dimension and one additional space dimension one can localize the symmetry which exists between generalized coordinate and their conjugate momenta. Such a localization implies the introduction of the gauge fields, which in turn implies the appearance of some first-class constraints. Choosing different gauge-fixing conditions and solving the constraints one obtain different time parameters, Hamiltonians, and generally, physical systems in the standard one time spacetime. In this way such systems as non-relativistic particle, relativistic particles, hydrogen atoms and harmonic oscillators were described as dual systems in the framework of the two time physics. Here, we find a set of gauge fixing conditions which provides as with such a parametrization of the phase space variables in the two time world which gives the description of Carroll particle in the one time world. Besides, we construct the quantum theory of such a particle using an unexpected correspondence between our parametrization and that obtained by Bars for the hydrogen atom in 1999.

Report on the Development of the Explorer App for Exploration of MHMD Data

Analytics

description: The main objective of WP8 is to demonstrate the feasibility of clinical applications using the MHMD infrastructure and to explore potential ways to unlock the value captured in large and distributed amounts of medical and non-medical data. In particular, several pilots should be developed to check the possibility of making use of securely anonymized or encrypted data for advanced data analytics and patient-specific and model-based prediction applications.
 For this specific deliverable, the relevant task is task 8.1 called “Data Exploration and Case-based Reasoning”. Here, the aim is to extend the CaseReasoner developed within the FP7 MD-Paedigree project using the API of task T5.8 and demonstrate the use of advanced analytics technologies such as deep learning in the secured data environment. The Explorer app should be extended to allow professional users to visualize data, explore patient graphs and perform patient stratification. During this step, a deep learning network should be trained with the data identified in the infrastructure.
 Within the context of all other tasks, task 8.1 deals with the evaluation of the MHMD infrastructure from the perspective of a research centre which is performing big data analytics including deep learning on MHMD data. We view it therefore as a key question whether tools can be developed that enable a research centre to interface with the MHMD infrastructure in an efficient way. In particular, the question should be answered how security-related processing within MHMD such as anonymization, encryption or watermarking would affect a typical big data analytics use case by a research centre.
 In the following sections, the system design, as well as the progress so far towards these goals, will be described.

description: This paper evaluates the parallel performance and scalability of an unstructured grid Shallow Water Equation (SWE) hurricane storm surge model. We use the ADCIRC model, which is based on the generalized wave continuity equation continuous Galerkin method, within a parallel computational framework based on domain decomposition and the MPI (Message Passing Interface) library. We measure the performance of the model run implicitly and explicitly on various grids. We analyze the performance as well as accurracy with various spatial and temporal discretizations. We improve the output writing performance by introducing sets of dedicated writer cores. Performance is measured on the Texas Advanced Computing Center Ranger machine. A high resolution 9,314,706 finite element node grid with 1s time steps can complete a day of real time hurricane storm surge simulation in less than 20 min of computer wall clock time, using 16,384 cores with sets of dedicated writer cores.

description: The efficiency of $H_2$ production via water electrolysis is typically limited to the sluggish oxygen evolution reaction (OER). As such, significant emphasis has been placed upon improving the rate of OER through the anode catalyst. More recently, the Open Catalyst 2022 (OC22) framework has provided a large dataset of density functional theory (DFT) calculations for OER intermediates on the surfaces of oxides. When coupled with state-of-the-art graph neural network models, total energy predictions can be achieved with a mean absolute error as low as 0.22 eV. In this work, we interpolated a database of the total energy predictions for all slabs and OER surface intermediates for 4,119 oxide materials in the original OC22 dataset using pre-trained models from the OC22 framework. This database includes all terminations of all facets up to a maximum Miller index of 1. To demonstrate the full utility of this database, we constructed a flexible screening framework to identify viable candidate anode catalysts for OER under varying reaction conditions for bulk, surface, and nanoscale Pourbaix stability as well as material cost, overpotential, and metastability. From our assessment, we were able to identify 122 and 68 viable candidates for OER under the bulk and nanoscale regime respectively.

description: We consider a partial differential equation that arises in the coarse-grained description of epitaxial growth processes. This is a parabolic equation whose evolution is governed by the competition between the determinant of the Hessian matrix of the solution and the biharmonic operator. This model might present a gradient flow structure depending on the boundary conditions. We first extend previous results on the existence of stationary solutions to this model for Dirichlet boundary conditions. For the evolution problem we prove local existence of solutions for arbitrary data and global existence of solutions for small data. By exploiting the boundary conditions and the variational structure of the equation, according to the size of the data we prove finite time blow-up of the solution and/or convergence to a stationary solution for global solutions.

description: The equations of secular evolution for dust grains in mean motion resonances with a planet are solved for stationary points. This is done including both Poynting-Robertson effect and stellar wind. The solutions are stationary in semimajor axis, eccentricity, and resonant angle, but allow the pericentre to advance. The semimajor axis of stationary solutions can be slightly shifted from the exact resonant value. The periodicity of the stationary solutions in a reference frame orbiting with the planet is analytically proved. The existence of periodic solutions in mean motion resonances means that analytical theory enables for dust particles also infinitely long capture times. The stationary solutions are periodic motions to which the eccentricity asymptotically approaches and around which the libration occurs. Using numerical integration of equation of motion are successfully found initial conditions corresponding to the stationary solutions. Numerically and analytically determined shifts of the semimajor axis form the exact resonance for the stationary solutions are in excellent agreement. The stationary solutions can be plotted by locations of pericenters in the reference frame orbiting with the planet. The pericenters are distributed in the space according to properties of dust particles.

The co-creation experience from the customer perspective: its measurement and determinants

description: Purpose – Companies increasingly opt for co-creation by engaging customers in new product and service development processes. This paper aims to provide insight into the customer experience in co-creation situations and its determinants. Design/methodology/approach – Our conceptual framework addresses (1) the customer experience in co-creation situations, and (2) its individual and environmental determinants. To examine the degree to which these determinants affect the customer experience in co-creation situations, we start by proposing and testing a multidimensional co-creation experience scale (n=66). Next, we employ an experiment to test our hypotheses (n=180). Findings – Higher levels of customer role readiness, technologization, and connectivity positively affect different co-creation experience dimensions. The impact of these dimensions on the overall co-creation experience, however, differs according to customers’ expectations in terms of co-creation benefits. Therefore, we conclude that the expected co-creation benefits determine the importance of the level of customer role readiness, technologization, and connectivity for the co-creation experience. Originality/value – This research generates a better understanding of the co-creation experience by providing insight into the co-creation experience dimensions and their relative importance for customers with different expectations in terms of co-creation benefits. Additionally, this research addresses the implications of customer heterogeneity in terms of expected co-creation benefits for designing co-creation environments, thereby helping managers to generate more rewarding co-creation experiences for their customers.

Handbook for Quantifying Robustness of Magic

description: The nonstabilizerness, or magic, is an essential quantum resource to perform universal quantum computation. Robustness of magic (RoM) in particular characterizes the degree of usefulness of a given quantum state for non-Clifford operation. While the mathematical formalism of RoM can be given in a concise manner, it is extremely challenging to determine the RoM in practice, since it involves superexponentially many pure stabilizer states. In this work, we present efficient novel algorithms to compute the RoM. The crucial technique is a subroutine that achieves the remarkable features in calculation of overlaps between pure stabilizer states: (i) the time complexity per each stabilizer is reduced exponentially, (ii) the space complexity is reduced superexponentially. Based on this subroutine, we present algorithms to compute the RoM for arbitrary states up to $n=7$ qubits on a laptop, while brute-force methods require a memory size of 86 TiB. As a byproduct, the proposed subroutine allows us to simulate the stabilizer fidelity up to $n=8$ qubits, for which naive methods require memory size of 86 PiB so that any state-of-the-art classical computer cannot execute the computation. We further propose novel algorithms that utilize the preknowledge on the structure of target quantum state such as the permutation symmetry of disentanglement, and numerically demonstrate our state-of-the-art results for copies of magic states and partially disentangled quantum states. The series of algorithms constitute a comprehensive ``handbook'' to scale up the computation of the RoM, and we envision that the proposed technique applies to the computation of other quantum resource measures as well.

Theory for Bose-Einstein condensation of light in nano-fabricated semiconductor microcavities

description: We construct a theory for Bose-Einstein condensation of light in nano-fabricated semiconductor microcavities. We model the semiconductor by one conduction and one valence band which consist of electrons and holes that interact via a Coulomb interaction. Moreover, we incorporate screening effects by using a contact interaction with the scattering length for a Yukawa potential and describe in this manner the crossover from exciton gas to electron-hole plasma as we increase the excitation level of the semiconductor. We then show that the dynamics of the light in the microcavities is damped due to the coupling to the semiconductor. Furthermore, we demonstrate that on the electron-hole plasma side of the crossover, which is relevant for the Bose-Einstein condensation of light, this damping can be described by a single dimensionless damping parameter that depends on the external pumping. Hereafter, we propose to probe the superfluidity of light in these nano-fabricated semiconductor microcavities by making use of the differences in the response in the normal or superfluid phase to a sudden rotation of the trap. In particular, we determine frequencies and damping of the scissors modes that are excited in this manner. Moreover, we show that a distinct signature of the dynamical Casimir effect can be observed in the density-density correlations of the excited light fluid.
title: Bacterial associations with commercially important marine bivalves

Subjects: subject: Biological oceanography, aquatic sciences.

description: This study is concerned with the interactions between bacteria and commercially important bivalves. It is divided into two sections, the first part consists of the isolation and identification of bacteria collected from hatcheries at Reculver, Guernsey and Conwy in the U.K. Identification of the bacteria was carried out using phenotypic analysis combined with numerical taxonomy. Results showed that diverse microbial flora was detected in these shellfish farms, and that the principal groups consisted of Vibrio, Enterobacter, Pseudomonas, Cytophaga, Flavobacterium, Moraxella, Micrococcus and Aeromonas species. The distribution of these bacteria was as follows; Vibrio were predominant at Guernsey whereas Enterobacter and Cytophaga were the most common isolates at Reculver and Conwy. Antibiotic resistance patterns were performed in order to establish the profile of bacterial resistance to commonly used aquaculture and medical important antibiotics. The outcome was a heterogenous resistance profile. Part two includes the analysis and screening of the tentatively identified bacterial isolates for their toxicity to bivalve haemocytes and known pathogens. In parallel other isolates from France, Spain, Norway and Scotland were included in the study for comparative analysis. Isolates were subjected to cytotoxicity tests in order to detect potential bivalve pathogens. A cytotoxocity test was developed and optimised for this purpose using natural conditions where possible. Alternative methods such as neutral red dye and molecular probes were used in order to obtain better results but were not successful. Thus visual observation of haemocyte-bacteria interactions proved to be more reliable. Principally bacteria from Vibrio and Cytophaga I Flavobacterium produced marked effects on haemocytes. Further tests revealed that this effect was more prominent in filtered haemolymph when compared to filtered sterile sea water. This was probably due to the presence of factor(s) that may have played an important role in this reaction, which merit further investigation to elucidate their exact role. Species specificity of several bacterial pathogens of bivalves is reflected in their interaction with bivalve haemocytes.

description: The sensitivity of the dark photon search through invisible decay final states in low background experiments significantly relies on the neutron and muon veto efficiency, which depends on the amount of material used and the design of detector geometry. This paper presents an optimized design of a hadronic calorimeter (HCAL) used for the DarkSHINE experiment, which is studied using a GEANT4-based simulation framework. The geometry is optimized by comparing a traditional design with uniform absorbers to one that uses different thicknesses at different locations of the detector, which enhances the efficiency of vetoing low-energy neutrons at the sub-GeV level. The overall size and total amount of material used in HCAL are optimized to be lower due to the load and budget requirements, while the overall performance is studied to meet the physical objectives.
