Anomalous Higgs-top Coupling Pollution on Triple Higgs Coupling Extraction at Future High-Luminosity Electron-Positron Collider

description: One of the most challenging tasks for future high-luminosity electron-positron colliders is to extract Higgs triple coupling. It was proposed that this can be carried out via the precisely measuring the cross section of ZH associated production up to $0.4\%$. In this paper, we example the possible heavy pollution from Higgs-top anomalous coupling. Our numerical results show that the pollution is small for $\sqrt{s}_{e^+e^-}= 240 GeV$. However for the higher energy collider, pollution is sizable, which should be taken into account. We further explored the possibility to measure CP-violated Higgs top coupling, via the forward-backward asymmetry $A_{FB}$ for the process $e^+e^- \rightarrow ZH$. The asymmetry can reach $0.7\%$ which is comparable to the precision of cross section measurement.

description: Here, we present an improved water quality index (WQI) model for assessment of coastal water quality using Cork Harbour, Ireland, as the case study. The model involves the usual four WQI components – selection of water quality indicators for inclusion, sub-indexing of indicator values, sub-index weighting and sub-index aggregation – with improvements to make the approach more objective and data-driven and less susceptible to eclipsing and ambiguity errors. The model uses the machine learning algorithm, XGBoost, to rank and select water quality indicators for inclusion based on relative importance to overall water quality status. Of the ten indicators for which data were available, transparency, dissolved inorganic nitrogen, ammoniacal nitrogen, BOD5, chlorophyll, temperature and orthophosphate were selected for summer, while total organic nitrogen, dissolved inorganic nitrogen, pH, transparency and dissolved oxygen were selected for winter. Linear interpolation functions developed using national recommended guideline values for coastal water quality are used for sub-indexing of water quality indicators and the XGBoost rankings are used in combination with the rank order centroid weighting method to determine sub-index weight values. Eight sub-index aggregation functions were tested - five from existing WQI models and three proposed by the authors. The computed indices were compared with those obtained using a multiple linear regression (MLR) approach and R2 and RMSE used as indicators of aggregation function performance. The weighted quadratic mean function (R2 = 0.91, RMSE = 4.4 for summer; R2 = 0.97, RMSE = 3.1 for winter) and the unweighted arithmetic mean function (R2 = 0.92, RMSE = 3.2 for summer; R2 = 0.97, RMSE = 3.2 for winter) proposed by the authors were identified as the best functions and showed reduced eclipsing and ambiguity problems compared to the others.

description: A physical self-learning machine can be defined as a nonlinear dynamical system that can be trained on data (similar to artificial neural networks), but where the update of the internal degrees of freedom that serve as learnable parameters happens autonomously. In this way, neither external processing and feedback nor knowledge of (and control of) these internal degrees of freedom is required. We introduce a general scheme for self-learning in any time-reversible Hamiltonian system. We illustrate the training of such a self-learning machine numerically for the case of coupled nonlinear wave fields.
Nucleotide sequence of cloned unintegrated avian sarcoma virus DNA: Viral DNA contains direct and inverted repeats similar to those in transposable elements

description: We have determined the nucleotide sequence of portions of two circular avian sarcoma virus (ASV) DNA molecules cloned in a prokaryotic host-vector system. The region whose sequence was determined represents the circle junction site - i.e., the site at which the ends of the unintegrated linear DNA are fused to form circular DNA. The sequence from one cloned molecule, SRA-2, shows that the circle junction site is the center of a 330-base-pair (bp) tandem direct repeat, presumably representing the fusion of the long terminal repeat (LTR) units known to be present at the ends of the linear DNA. The circle junction site is also the center of a 15-bp imperfect inverted repeat, which thus appears at the boundaries of the LTR. The structure of ASV DNA - unique coding region flanked by a direct repeat that is, in turn, terminated with a short inverted repeat - is very similar to the structure of certain transposable elements. Several features of the sequence imply that circularization to from the SRA-2 molecule occurred without loss of information from the linear DNA precursor. Circularization of another cloned viral DNA molecule, SRA-1, probably occurred by a different mechanism. The circle junction site of the SRA-1 molecule has a 63-bp deletion, which may have arisen by a mechanism that is analogous to the integration of viral DNA into the host genome. Flanking one side of the tandem direct repeat is the binding site for tRNA(Trp), (Trp), the previously described primer for synthesis of the first strand of viral DNA. The other side of the direct repeat is flanked by a polypurine tract, A-G-G-G-A-G-G-G-G-G-A, which may represent the position of the primer for synthesis of the second strand of viral DNA. An A+T-rich region, upstream from the RNA capping site, and the sequence A-A-T-A-A-A are present within the direct repeat sequence. These sequences may serve as a promoter site and poly(A) addition signal, respectively, as proposed for other eukaryotic transcription units.

description: We experimentally demonstrate the generation of spin-wave frequency combs based on the nonlinear interaction of propagating spin waves in a microstructured waveguide. By means of time and space-resolved Brillouin light scattering spectroscopy, we show that the simultaneous excitation of spin waves with different frequencies leads to a cascade of four-magnon scattering events which ultimately results in well-defined frequency combs. Their spectral weight can be tuned by the choice of amplitude and frequency of the input signals. Furthermore, we introduce a model for stimulated four-magnon scattering which describes the formation of spin-wave frequency combs in the frequency and time domain.

description: Measurement in biological systems became a subject of concern as a consequence of numerous reports on limited reproducibility of experimental results. To reveal origins of this inconsistency, we have examined general features of biological systems as dynamical systems far from not only their chemical equilibrium, but, in most cases, also of their Lyapunov stable states. Thus, in biological experiments, we do not observe states, but distinct trajectories followed by the examined organism. If one of the possible sequences is selected, a minute sub-section of the whole problem is obtained, sometimes in a seemingly highly reproducible manner. But the state of the organism is known only if a complete set of possible trajectories is known. And this is often practically impossible. Therefore, we propose a different framework for reporting and analysis of biological experiments, respecting the view of non-linear mathematics. This view should be used to avoid overoptimistic results, which have to be consequently retracted or largely complemented. An increase of specification of experimental procedures is the way for better understanding of the scope of paths, which the biological system may be evolving. And it is hidden in the evolution of experimental protocols.

Delay-Robust Nonlinear Control of Bounded-Input Telerobotic Systems with Synchronization Enhancement

This paper puts forward a novel controller for joint position tracking of bilateral teleoperation systems subjected simultaneously to time-varying communication delays and bounded actuation. Enhancing such systems’ robustness to the larger time delays comes prevalently at the cost of increased settling time for position synchronization. To this end, we propose a general and refined form of nP+D controller that not only mitigates the trade-off between settling time of synchronization and magnitude of time-delay but also exhibits better transient error in position convergence. These advantages are brought along through using capped joint-velocity in the controller, which offers a blessing in disguise in our presented Lyapunov-based stability analysis and allows disposing of the limitation that was originally considered on the nonlinear function’s amplitude in previous nP+D controllers. We have shown that by setting conditions on the controller parameters obtained from the analytical study, the closed-loop dynamics’ asymptotic stability is ensured. The proposed controller’s efficacy and outperformance are validated through numerical simulations and experimental evaluations on a bilateral teleoperation system with multi-DOF robots as the leader and follower.

description: In this work we examine the turbulence maintained in a Restricted Nonlinear (RNL) model of plane Couette flow. This model is a computationally efficient approximation of the second order statistical state dynamics (SSD) obtained by partitioning the flow into a streamwise averaged mean flow and perturbations about that mean, a closure referred to herein as the RNL$_\infty$ model. The RNL model investigated here employs a single member of the infinite ensemble that comprises the covariance of the RNL$_\infty$ dynamics. The RNL system has previously been shown to support self-sustaining turbulence with a mean flow and structural features that are consistent with DNS. This paper demonstrates that the RNL system's self-sustaining turbulent state is supported by a small number of streamwise varying modes, which form the natural support for the self-sustaining process maintaining RNL turbulence. Remarkably, truncation of the RNL system's support to a single streamwise varying mode can suffice to sustain the turbulent state. The close correspondence between RNL simulations and DNS that has been previously observed along with the results presented here suggest that the fundamental mechanisms underlying wall-turbulence can be analyzed using these highly simplified RNL systems.

description: Left ventricular hypertrophy (LVH) results from chronic remodeling caused by a broad range of systemic and cardiovascular disease including hypertension, aortic stenosis, hypertrophic cardiomyopathy, and cardiac amyloidosis. Early detection and characterization of LVH can significantly impact patient care but is limited by under-recognition of hypertrophy, measurement error and variability, and difficulty differentiating etiologies of LVH. To overcome this challenge, we present EchoNet-LVH - a deep learning workflow that automatically quantifies ventricular hypertrophy with precision equal to human experts and predicts etiology of LVH. Trained on 28,201 echocardiogram videos, our model accurately measures intraventricular wall thickness (mean absolute error [MAE] 1.4mm, 95% CI 1.2-1.5mm), left ventricular diameter (MAE 2.4mm, 95% CI 2.2-2.6mm), and posterior wall thickness (MAE 1.2mm, 95% CI 1.1-1.3mm) and classifies cardiac amyloidosis (area under the curve of 0.83) and hypertrophic cardiomyopathy (AUC 0.98) from other etiologies of LVH. In external datasets from independent domestic and international healthcare systems, EchoNet-LVH accurately quantified ventricular parameters (R2 of 0.96 and 0.90 respectively) and detected cardiac amyloidosis (AUC 0.79) and hypertrophic cardiomyopathy (AUC 0.89) on the domestic external validation site. Leveraging measurements across multiple heart beats, our model can more accurately identify subtle changes in LV geometry and its causal etiologies. Compared to human experts, EchoNet-LVH is fully automated, allowing for reproducible, precise measurements, and lays the foundation for precision diagnosis of cardiac hypertrophy. As a resource to promote further innovation, we also make publicly available a large dataset of 23,212 annotated echocardiogram videos.

description: Herein, we present a new collaborative clinical simulation (CCS) model for the development of medical competencies by medical students. The model is a comprehensive compendium of published considerations and recommendations on clinical simulation (CS) and computer-supported collaborative learning (CSCL). Currently, there are no educational models combining CS and CSCL. The CCS model was designed for the acquisition and assessment of clinical competencies; working collaboratively and supported by technology, small groups of medical students independently design and perform simulated cases. The model includes four phases in which the learning objectives, short case scenarios, materials, indices, and the clinical simulation are designed, monitored, rated and debriefed.

description: The genomes of numerous avian retroviruses contain at their 3′ termini a conserved domain denoted "c". The precise boundaries and function of "c" have been enigmas. In an effort to resolve these issues, we determined the sequerce of over 900 nucleotides at the 3′ end of the genome of the Schmidt-Ruppin subgroup A strain of avian sarcoma virus (ASV). We obtained the sequence from a Suitable fragment of ASV DNA that had been cloned into the single-stranded DNA phage M13mp2. Computer-assisted analysis of the sequence revealed the following structural features: i) the length of "C" - 473 nucleotides; ii) the 3′ terminal domain of src, ending in an amber codon at the 5′ boundary of "C"; iii) terminator codons that preclude continuous translation from "C"; iv) suitably located sequerces that may serve as signals for the initiation of viral RNA synthesis and for the processing and/or polyadenylation of viral mRNA;v) a repeated sequerce that flanks src and that could facilitate deletion of this gene; vi) repeated sequences within "c"; and vii) unexplained homologies between sequences in "c" and sequerces in several other nucleic acids, including the 5′ terminal domain of the ASV genome tRNATIP and its inversion, the complement of tRNATIP and its inversion, and the 18S RNA of eukaryotic ribosomas. We cocnclude that "c" probably does not encode a protein, but its sequence may nevertheless serve several essential functions in viral replication. © 1980 IRL Press Limited.

description: The aim of the present master’s thesis is the study of the green choices that the states worldwide and specifically the dominant geopolitical formations like the China – Russia axis and the European Union – United States of America have adopted mainly in the context of their foreign policy in order to obtain a position of power on the changing geopolitical map as evidenced by the current geopolitical situation (Russian-Ukrainian conflict). Under the banner of "green development", the states are led to various geopolitical options, shaping a new energy world and at the same time a new geopolitical one. Throughout the essay, this interaction of geography and energy becomes apparent as well as how this energy transition will affect the geopolitical formations. It is specifically studied in which ways the green transition is implemented, how it affects energy security and states as producers and consumers in the world of fossil fuels and green energy and whether we can ultimately refer to winners and losers during the transition but also after its completion.

description: There is some risk of disclosing identities of individuals (or entities) and their sensitive data that exists in every data file that is released. A privacy policy should describe a process that considers whether the release of the data file followed reasonable procedures and a process that applies appropriate data use restrictions and access controls. At the very least, the risk of re- identification should be minimized after considering the possible approaches to re-identify persons using existing technology and public or commercially available information. Furthermore, it is important to be aware that the privacy of individuals can be impacted by a data release whether or not the person is in the file.

The latter are given by linear categories with new additional structure which we call Hopf linear categories over a finite group. We compare this invariant to the fundamental group of the underlying linear category, and we compute those groups for families of examples.
description: Computations of the fundamental group of some Hopf algebras are added. The relation with the fundamental group of the underlying associative structure is now considered. We also analyse the situation when universal covers and/or gradings exist. Dedicated to Eduardo N. Marcos for his 60th birthday. 24 pages

description: Many practical sensing applications involve multiple sensors simultaneously acquiring measurements of a single object. Conversely, most existing sparse recovery guarantees in compressed sensing concern only single-sensor acquisition scenarios. In this paper, we address the optimal recovery of compressible signals from multi-sensor measurements using compressed sensing techniques, thereby confirming the benefits of multi- over single-sensor environments. Throughout the paper, we consider a broad class of sensing matrices, and two fundamentally different sampling scenarios (distinct and identical respectively), both of which are relevant to applications. For the case of diagonal sensor profile matrices (which characterize environmental conditions between a source and the sensors), this paper presents two key improvements over existing results. First, a simpler optimal recovery guarantee for distinct sampling, and second, an improved recovery guarantee for identical sampling, based on the so-called sparsity in levels signal model.

description: Deep learning based Quantitative Susceptibility Mapping (QSM) has shown great potential in recent years, obtaining similar results to established non-learning approaches. Many current deep learning approaches are not data consistent, require in vivo training data or solve the QSM problem in consecutive steps resulting in the propagation of errors. Here we aim to overcome these limitations and developed a framework to solve the QSM processing steps jointly. We developed a new hybrid training data generation method that enables the end-to-end training for solving background field correction and dipole inversion in a data-consistent fashion using a variational network that combines the QSM model term and a learned regularizer. We demonstrate that NeXtQSM overcomes the limitations of previous deep learning methods. NeXtQSM offers a new deep learning based pipeline for computing quantitative susceptibility maps that integrates each processing step into the training and provides results that are robust and fast.

description: The specific interactions between the RNA-directed DNA polymerase of avian oncornavirus and the tRNATrp primer required for initiation of viral DNA synthesis in vitro were examined. Two distinct interactions, stable binding of the tRNATrp to the enzyme and initiation of viral DNA synthesis by the enzyme with tRNATrp as primer, were characterized as to the structure of tRNATrp required. Different structural features of the tRNATrp were shown to be necessary for each type of interaction. The entire primary structure and native conformation of tRNATrp are both required for binding to reverse transcriptase. Fragments of tRNATrp and intact tRNATrp in an altered conformation cannot be bound by the enzyme using an assay which detects high affinity binding between reverse transcriptase and native tRNATrp. In contrast, fragments of the tRNATrp molecule can serve as primers for viral DNA synthesis with normal efficiency as compared to intact tRNATrp. The fragments which initiate transcription must contain a minimum specific nucleotide sequence which extends from the 3' terminus of the tRNATrp through 27 residues of the molecule. This portion of the tRNATrp may be a major structural determinant of specificity in initiation.

description: Il contributo propone una riflessione sugli effetti del Covid-19 sulla situazione delle donne in Italia, prendendo in esame alcuni temi al centro della Convenzione di Istanbul, in particolare la violenza domestica e le misure di protezione, la parità di genere, sia nel contesto delle posizioni di potere (ceiling glass), sia nel contesto del lavoro e della salute riproduttiva. Il contributo evidenzia come già prima della pandemia, nel nostro paese le azioni di contrasto alla violenza e alla disparità di genere fossero largamente insufficienti, e come la pandemia si configuri, in assenza di una sistematica adozione di una prospettiva di genere, come una condizione destinata ad aumentare le diseguaglianze.

description: Using Gauss diagrams, one can define the virtual bridge number ${\rm vb}(K)$ and the welded bridge number ${\rm wb}(K),$ invariants of virtual and welded knots with ${\rm wb}(K) \leq {\rm vb}(K).$ If $K$ is a classical knot, Chernov and Manturov showed that ${\rm vb}(K) = {\rm br}(K),$ the bridge number as a classical knot, and we ask whether the same thing is true for welded knots. The welded bridge number is bounded below by the meridional rank of the knot group $G_K$, and we use this to relate this question to a conjecture of Cappell and Shaneson. We show how to use other virtual and welded invariants to further investigate bridge numbers. Among them are Manturov's parity and the reduced virtual knot group $\overline{G}_K$, and we apply these methods to address Questions 6.1, 6.2, 6.3 and 6.5 raised by Hirasawa, Kamada and Kamada in their paper "Bridge presentation of virtual knots," J. Knot Theory Ramifications 20 (2011), no. 6, 881--893.

description: The problem of multiple sensors simultaneously acquiring measurements of a single object can be found in many applications. In this paper, we present the optimal recovery guarantees for the recovery of compressible signals from multi-sensor measurements using compressed sensing. In the first half of the paper, we present both uniform and nonuniform recovery guarantees for the conventional sparse signal model in a so-called distinct sensing scenario. In the second half, using the so-called sparse and distributed signal model, we present nonuniform recovery guarantees which effectively broaden the class of sensing scenarios for which optimal recovery is possible, including to the so-called identical sampling scenario. To verify our recovery guarantees we provide several numerical results including phase transition curves and numerically-computed bounds.

description: We study the driven-dissipative steady-state of a coherently-driven Bose field in a honeycomb lattice geometry. In the presence of a suitable spatial modulation of the hopping amplitudes, a valley-dependent artificial magnetic field appears and the low-energy eigenmodes have the form of relativistic Landau levels. We show how the main properties of the Landau levels can be extracted by observing the peaks in the absorption spectrum of the system and the corresponding spatial intensity distribution. Finally, quantitative predictions for realistic lattices based on photonic or microwave technologies are discussed.

description: Due to the unique characteristics of small-and-medium sized enterprises (SMEs), critical success factors (CSFs) identified in the context of large enterprises may not be readily applicable to SMEs. This paper aims to enhance the current understanding of CSFs for ES implementation in SMEs. It synthesizes a set of CSFs that are likely to be significant for ES implementation in SMEs and then explores the perception of 30 SMEs regarding influential CSFs through an analysis of online customer success stories. The study highlights some differences in CSF identified in the literature and those perceived by SMEs. By identifying CSFs of high importance within the context of SMEs this study improves the prospects of successful ES implementation. It also identifies knowledge gaps that could be addressed in future studies to enhance the current understanding of CSFs for ES implementations in SMEs.
Dynamics of elastic dumbbells sedimenting in a viscous fluid: oscillations and hydrodynamic repulsion

description: Hydrodynamic interactions between two identical elastic dumbbells settling under gravity in a viscous fluid at low-Reynolds-number are investigated within the point-particle model. Evolution of a benchmark initial configuration is studied, in which the dumbbells are vertical and their centres are aligned horizontally. Rigid dumbbells and pairs of separate beads starting from the same positions tumble periodically while settling down. We find that elasticity (which breaks time-reversal symmetry of the motion) significantly affects the system's dynamics. This is remarkable taking into account that elastic forces are always much smaller than gravity. We observe oscillating motion of the elastic dumbbells, which tumble and change their length non-periodically. Independently of the value of the spring constant, a horizontal hydrodynamic repulsion appears between the dumbbells - their centres of mass move apart from each other horizontally. The shift is fast for moderate values of the spring constant k, and slows down when k tends to zero or to infinity; in these limiting cases we recover the periodic dynamics reported in the literature. For moderate values of the spring constant, and different initial configurations, we observe the existence of a universal time-dependent solution to which the system converges after an initial relaxation phase. The tumbling time and the width of the trajectories in the centre-of-mass frame increase with time. In addition to its fundamental significance, the benchmark solution presented here is important to understand general features of systems with larger number of elastic particles, at regular and random configurations.

On the bilateral preconditioning for an L2-type all-at-once system arising from time-space fractional Bloch-Torrey equations

description: Time-space fractional Bloch-Torrey equations (TSFBTEs) are developed by some researchers to investigate the relationship between diffusion and fractional-order dynamics. In this paper, we first propose a second-order implicit difference scheme for TSFBTEs by employing the recently proposed L2-type formula [A.~A.~Alikhanov, C.~Huang, Appl.~Math.~Comput.~(2021) 126545]. Then, we prove the stability and the convergence of the proposed scheme. Based on such a numerical scheme, an L2-type all-at-once system is derived. In order to solve this system in a parallel-in-time pattern, a bilateral preconditioning technique is designed to accelerate the convergence of Krylov subspace solvers according to the special structure of the coefficient matrix of the system. We theoretically show that the condition number of the preconditioned matrix is uniformly bounded by a constant for the time fractional order $α\in (0,0.3624)$. Numerical results are reported to show the efficiency of our method.

The index of families of projective operators

description: Let $1 \to Γ\to \tilde{G} \to G \to 1$ be a central extension by an abelian finite group. In this paper, we compute the index of families of $\tilde{G}$-transversally elliptic operators on a $G$-principal bundle $P$. We then introduce the notion of families of projective operators on fibrations equipped with an Azumaya bundle $\mathcal{A}$. We define and compute the index of such families using the cohomological index formula for families of $SU(N)$-transversally elliptic operators. More precisely, a family $A$ of projective operators can be pulled back in a family $\tilde{A}$ of $SU(N)$-transversally elliptic operators on the $PU(N)$-principal bundle of trivialisations of $\mathcal{A}$. Through the distributional index of $\tilde{A}$, we can define an index for the family $A$ of projective operators and using the index formula in equivariant cohomology for families of $SU(N)$-transversally elliptic operators, we derive an explicit cohomological index formula in de Rham cohomology. Once this is done, we define and compute the index of families of projective Dirac operators. As a second application of our computation of the index of families of $\tilde{G}$-transversally elliptic operators on a $G$-principal bundle $P$, we consider the special case of a family of $Spin(2n)$-transversally elliptic Dirac operators over the bundle of oriented orthonormal frames of an oriented fibration and we relate its distributional index with the index of the corresponding family of projective Dirac operators.

description: ANGEL’s Global Education Digest, developed by the Development Education Research Centre and UNESCO Chair in GCED in Higher Education at the University of Bologna, provides a reasoned bibliography of academic materials and policy documents relevant to the field of global education. It covers the material that has been published recently in 10 European languages (English, Dutch, Finnish, French, German, Italian, Polish, Portuguese, Slovakian, and Spanish). Global Education served as an umbrella for differing traditions while putting an enlightening educational process and values of equity, sustainability and human rights at the core of the process. ANGEL network and Global Education Network Europe (GENE) have used this definition of Global Education for almost 20 years and it is widely recognised and available in multiple languages. Global Education is understood to encompass Development Education, Human Rights Education, Education for Sustainability, Education for Peace and Conflicts prevention and Intercultural Education; being the global dimensions of Education for citizenship. The Global Education Digest project is an initiative that is growing in three key dimensions: in the number of languages featured, in the numbers and nationalities of contributors, and in breadth of format— with the creation of a digital archive. Despite our efforts to look beyond European boundaries, through publications and contributors that come from other continents, this project currently offers mostly an analysis on Global Education in Europe. The Digest publications are cooperative projects, with contributors drawn from amongst the ANGEL network’s growing membership. The number of contributors involved this year increased from 25 to 36, and from 13 different countries. The main goals of the project are: a) to provide a comprehensive picture of the relevant literature published in Global Education (GE) in widely spoken languages, b) Provide a project and a resource that would enhance and develop the ANGEL community, strengthening the network of researchers working in Europe on Global Citizenship Education (GCE).
