Control system based on Highly Abstracted and Open Structure
INFN-16-06-LNF

description: The !CHAOS project has been devoted to the realization of a prototype of Control as a Service open platform suited for a large number of applications in science, industry and society. The Control Server concept has been introduced to give emphasis to the innovative !CHAOS architecture that is represented by a scalable and distributed cloud-like infrastructure providing the services needed for implementing distributed control and data acquisition systems. The project is based on the results of an R&D initiative promoted by INFN-LNF and INFN-Roma "Tor Vergata", aimed to the development of a new architecture for controls of large experimental infrastructures named !CHAOS (Control system based on Highly Abstracted and Open Structure). To fully profit from this new technologies the control system model has been reconsidered, thus leading to the definition of the new !CHAOS "control service" paradigm. The key features and development strategies of !CHAOS are: • scalability of performances and size • integration of all functionalities • abstraction of services, devices and data • easy and modular customization • extensive data catching for performance boost • use of high-performance internet software technologies. In 2015 the !CHAOS project, partially supported by the CNS5, concluded the activities foreseen by the "Premiale" proposal1. Two main deliverables were scheduled for 2015: firstly the release of an Alpha version in June, as conclusion of the design study of all the tasks planned in the project and the development and integration of its core functionality; secondly the release, by the end of the year, of a Beta version where all the functionalities expected have been developed, integrated, tested and qualified. All deliverables and milestones expected by "Premiale" proposal have been achieved without significant deviations. The project has been demonstrated the feasibility of building a scalable multipurpose controls services provider based on the !CHAOS framework and on the INFN e-infrastructure allowing, with unprecedented flexibility, the monitoring, control and data acquisition, storage and analysis of any sensors, devices and SoS.

description: We demonstrate theoretically that shining light on superconducting proximity structures controls the minigap and triplet proximity effect in normal and magnetic metals, respectively. Considering both a bilayer and Josephson junction geometry, we show that microwave irradiation with frequency $ω$ qualitatively alters the spectral properties of the system, controlling the minigap size $E_\text{mg}$ and even replacing the minigap with a strong peak of quasiparticle accumulation at zero energy when $ω=E_\text{mg}$. The interaction between light and Cooper pairs may thus open a route to active control of quantum coherent phenomena in superconducting proximity structures.

description: We present key results from the Herschel Orion Protostar Survey (HOPS): spectral energy distributions (SEDs) and model fits of 330 young stellar objects, predominantly protostars, in the Orion molecular clouds. This is the largest sample of protostars studied in a single, nearby star-formation complex. With near-infrared photometry from 2MASS, mid- and far-infrared data from Spitzer and Herschel, and sub-millimeter photometry from APEX, our SEDs cover 1.2-870 $μ$m and sample the peak of the protostellar envelope emission at ~100 $μ$m. Using mid-IR spectral indices and bolometric temperatures, we classify our sample into 92 Class 0 protostars, 125 Class I protostars, 102 flat-spectrum sources, and 11 Class II pre-main-sequence stars. We implement a simple protostellar model (including a disk in an infalling envelope with outflow cavities) to generate a grid of 30400 model SEDs and use it to determine the best-fit model parameters for each protostar. We argue that far-IR data are essential for accurate constraints on protostellar envelope properties. We find that most protostars, and in particular the flat-spectrum sources, are well-fit. The median envelope density and median inclination angle decrease from Class 0 to Class I to flat-spectrum protostars, despite the broad range in best-fit parameters in each of the three categories. We also discuss degeneracies in our model parameters. Our results confirm that the different protostellar classes generally correspond to an evolutionary sequence with a decreasing envelope infall rate, but the inclination angle also plays a role in the appearance, and thus interpretation, of the SEDs.

End-point singularity of the $XY$-paramagnetic phase boundary for the $(2+1)$D $S=1$ square-lattice $J_1$-$J_2$ $XY$ model with the single-ion anisotropy

description: The two-dimensional quantum spin-$S=1$ square-lattice $J_1$-$J_2$ $XY$ model with the single-ion anisotropy $D$ was investigated numerically, placing an emphasis on the end-point singularity of the phase boundary separating the $XY$ and paramagnetic phases in proximity to the fully frustrated point, $J_2/J_1 \to 0.5^{-}$. We employed the exact diagonalization method to circumvent the negative sign problem of the quantum Monte Carlo method, and evaluated the fidelity susceptibility $χ_F$ as a probe to detect the phase transition. As a preliminary survey, for an intermediate value of $J_2/J_1$, the $D$-driven $XY$-paramagnetic phase transition was investigated via the probe $χ_F$. It turned out that the criticality belongs to the $3$D-$XY$ universality class. Thereby, the $χ_F$ data were cast into the crossover-scaling formula with the properly scaled distance from the multi-critical point, $0.5-J_2/J_1$. The set of multi-critical indices were obtained, and compared to those of the quantum Lifshitz criticality.

description: Automatic recognition of spontaneous facial expressions is a major challenge in the field of affective computing. Head rotation, face pose, illumination variation, occlusion etc. are the attributes that increase the complexity of recognition of spontaneous expressions in practical applications. Effective recognition of expressions depends significantly on the quality of the database used. Most well-known facial expression databases consist of posed expressions. However, currently there is a huge demand for spontaneous expression databases for the pragmatic implementation of the facial expression recognition algorithms. In this paper, we propose and establish a new facial expression database containing spontaneous expressions of both male and female participants of Indian origin. The database consists of 428 segmented video clips of the spontaneous facial expressions of 50 participants. In our experiment, emotions were induced among the participants by using emotional videos and simultaneously their self-ratings were collected for each experienced emotion. Facial expression clips were annotated carefully by four trained decoders, which were further validated by the nature of stimuli used and self-report of emotions. An extensive analysis was carried out on the database using several machine learning algorithms and the results are provided for future reference. Such a spontaneous database will help in the development and validation of algorithms for recognition of spontaneous expressions.

description: The entanglement spectrum of the reduced density matrix contains information beyond the von Neumann entropy and provides unique insights into exotic orders or critical behavior of quantum systems. Here, we show that strongly disordered systems in the many-body localized phase have power-law entanglement spectra, arising from the presence of extensively many local integrals of motion. The power-law entanglement spectrum distinguishes many-body localized systems from ergodic systems, as well as from ground states of gapped integrable models or free systems in the vicinity of scale-invariant critical points. We confirm our results using large-scale exact diagonalization. In addition, we develop a matrix-product state algorithm which allows us to access the eigenstates of large systems close to the localization transition, and discuss general implications of our results for variational studies of highly excited eigenstates in many-body localized systems.

Variational Monte Carlo study of chiral spin liquid in quantum antiferromagnet on the triangular lattice

description: By using Gutzwiller projected fermionic wave functions and variational Monte Carlo technique, we study the spin-$1/2$ Heisenberg model with the first-neighbor ($J_1$), second-neighbor ($J_2$), and additional scalar chiral interaction $J_χ{\bf S}_i \cdot ({\bf S}_j \times {\bf S}_k)$ on the triangular lattice. In the non-magnetic phase of the $J_1-J_2$ triangular model with $0.08 \lesssim J_2/J_1 \lesssim 0.16$, recent density-matrix renormalization group (DMRG) studies [Zhu and White, Phys. Rev. B {\bf 92}, 041105 (2015); Hu, Gong, Zhu, and Sheng, Phys. Rev. B {\bf 92}, 140403 (2015)] find a possible gapped spin liquid with the signal of a competition between a chiral and a $Z_2$ spin liquid. Motivated by the DMRG results, we consider the chiral interaction $J_χ{\bf S}_i \cdot ({\bf S}_j \times {\bf S}_k)$ as a pertubation for this non-magnetic phase. We find that with growing $J_χ$, the gapless U(1) Dirac spin liquid, which has the best variational energy for $J_χ=0$, exhibits the energy instability towards a gapped spin liquid with non-trivial magnetic fluxes and nonzero chiral order. We calculate topological Chern number and ground-state degeneracy, both of which identify this flux state as the chiral spin liquid with fractionalized Chern number $C=1/2$ and two-fold topological degeneracy. Our results indicate a positive direction to stabilize a chiral spin liquid near the non-magnetic phase of the $J_1-J_2$ triangular model.

description: Ultrafast all-fiber Yb-doped fiber oscillators are usually associated with all-normal-dispersion cavities, which operate in a dissipative soliton regime, quintessential for pulsed operation at the wavelength of 1 μm. This work presents an all-polarization-maintaining Yb-doper fiber laser oscillator that operates in a dispersion-managed dissipative soliton regime, thanks to incorporating a chirped fiber Bragg grating. The oscillator, mode-locked via a nonlinear optical loop mirror, has an unconventional semi-linear cavity of net anomalous dispersion. Unlike in standard ring resonators, the ultrashort pulse undergoes amplification twice per cavity roundtrip. Additionally, we report a duality of pulsed operation states depending on the pumping power. Strikingly, the oscillator can work in a~subregime similar to the standard dissipative soliton, facilitating further energy scaling at anomalous dispersion. We characterize the low-noise setup capable of delivering pulse energy as high as 6.4 nJ using standard single-mode polarization-maintaining optical fibers.

description: We introduce a string-based parametrization for nucleon quark and gluon generalized parton distributions (GPDs) that is valid for all skewness. Our approach leverages conformal moments, representing them as the sum of spin-j nucleon A-form factor and skewness-dependent spin-j nucleon D-form factor, derived from t-channel string exchange in AdS spaces consistent with Lorentz invariance and unitarity. This model-independent framework, satisfying the polynomiality condition due to Lorentz invariance, uses Mellin moments from empirical data to estimate these form factors. With just five Regge slope parameters, our method accurately produces various nucleon quark GPD types and symmetric nucleon gluon GPDs through pertinent Mellin-Barnes integrals. Our isovector nucleon quark GPD is in agreement with existing lattice data, promising to improve the empirical extraction and global analysis of nucleon GPDs in exclusive processes, by avoiding the deconvolution problem at any skewness, for the first time.

Relation Between Stereographic Projection and Concurrence Measure in Bipartite Pure States

description: One-qubit pure states, living on the surface of Bloch sphere, can be mapped onto the usual complex plane by using stereographic projection. In this paper, after reviewing the entanglement of two-qubit pure state, it is shown that the \emph{quaternionic} stereographic projection is related to concurrence measure. This is due to the fact that every two-qubit state, in ordinary complex field, corresponds to the one-qubit state in quaternionic skew field, called quaterbit. Like the one-qubit states in complex field, the stereographic projection maps every quaterbit onto a quaternion number whose complex and quaternionic parts are related to Schmidt and concurrence terms respectively. Rather, the same relation is established for three-qubit state under \emph{octonionic} stereographic projection which means that if the state is bi-separable then, quaternionic and octonionic terms vanish. Finally, we generalize recent consequences to $2 \otimes N$ and $4\otimes N$ dimensional Hilbert spaces ($N\geq 2$) and show that, after stereographic projection, the quaternionic and octonionic terms are entanglement sensitive. These trends are easily confirmed by direct computation for general multi-particle W- and GHZ-states.

description: Recent years have seen an enormously revived interest in the study of thermodynamic notions in the quantum regime. This applies both to the study of notions of work extraction in thermal machines in the quantum regime, as well as to questions of equilibration and thermalisation of interacting quantum many-body systems as such. In this work we bring together these two lines of research by studying work extraction in a closed system that undergoes a sequence of quenches and equilibration steps concomitant with free evolutions. In this way, we incorporate an important insight from the study of the dynamics of quantum many body systems: the evolution of closed systems is expected to be well described, for relevant observables and most times, by a suitable equilibrium state. We will consider three kinds of equilibration, namely to (i) the time averaged state, (ii) the Gibbs ensemble and (iii) the generalised Gibbs ensemble (GGE), reflecting further constants of motion in integrable models. For each effective description, we investigate notions of entropy production, the validity of the minimal work principle and properties of optimal work extraction protocols. While we keep the discussion general, much room is dedicated to the discussion of paradigmatic non-interacting fermionic quantum many-body systems, for which we identify significant differences with respect to the role of the minimal work principle. Our work not only has implications for experiments with cold atoms, but also can be viewed as suggesting a mindset for quantum thermodynamics where the role of the external heat baths is instead played by the system itself, with its internal degrees of freedom bringing coarse-grained observables to equilibrium.

description: The concept of symmetry breaking has been a propelling force in understanding phases of matter. While rotational symmetry breaking is one of the most prevalent examples, the rich landscape of orientational orders breaking the rotational symmetries of isotropic space, i.e. $O(3)$, to a three-dimensional point group remain largely unexplored, apart from simple examples such as ferromagnetic or uniaxial nematic ordering. Here we provide an explicit construction, utilizing a recently introduced gauge theoretical framework, to address the three-dimensional point-group-symmetric orientational orders on a general footing. This unified approach allows us to enlist order parameter tensors for all three dimensional point groups. By construction, these tensor order parameters are the minimal set of simplest tensors allowed by the symmetries that uniquely characterize the orientational order. We explicitly give these for the point groups $\{C_n, D_n, T, O, I\} \subset SO(3)$ and $\{C_{nv}, S_n, C_{nh}, D_{nh}, D_{nd}, T_h, T_d, O_h, I_h\}\subset O(3)$ for $n=\{1,2,3,4,6, \infty\}$. This central result may be perceived as a roadmap for identifying exotic orientational orders that may become more and more in reach in view of rapid experimental progress in e.g. nano-colloidal systems and novel magnets.

The effect is pronounced in the region of charge carrier doping $x$ with strong spin-charge stripe correlations, reaching $T_{cs}=36$ K or 1.64$T_c$.

Learned Thresholds Token Merging and Pruning for Vision Transformers

description: Vision transformers have demonstrated remarkable success in a wide range of computer vision tasks over the last years. However, their high computational costs remain a significant barrier to their practical deployment. In particular, the complexity of transformer models is quadratic with respect to the number of input tokens. Therefore techniques that reduce the number of input tokens that need to be processed have been proposed. This paper introduces Learned Thresholds token Merging and Pruning (LTMP), a novel approach that leverages the strengths of both token merging and token pruning. LTMP uses learned threshold masking modules that dynamically determine which tokens to merge and which to prune. We demonstrate our approach with extensive experiments on vision transformers on the ImageNet classification task. Our results demonstrate that LTMP achieves state-of-the-art accuracy across reduction rates while requiring only a single fine-tuning epoch, which is an order of magnitude faster than previous methods. Code is available at https://github.com/Mxbonn/ltmp .

description: In this Letter, both the manipulation of valley-polarized currents and the optical-like behaviors of Dirac fermions are theoretically explored in polycrystalline graphene. When strain is applied, the misorientation between two graphene domains separated by a grain boundary can result in a mismatch of their electronic structures. Such a discrepancy manifests itself in a strong breaking of the inversion symmetry, leading to perfect valley polarization in a wide range of transmission directions. In addition, these graphene domains act as different media for electron waves, offering the possibility to modulate and obtain negative refraction indexes.

description: In the current situation of a biodiversity crisis, we look for a more holistic and integrative way to address the ongoing problems and find influential solutions in traditional research fields such as insect systematics and phylogeny. Lepidoptera as the most studied, loved and collected insect group provides endless possibilities to integrate the visual, bionomical, genomic, and distribution/observation data into a broader pattern of machine-readable models and approaches that help to understand the complexity of evolutional processes, especially in the Global South. Within the proposed symposium we aim to invite speakers that have already made a significant contribution in creating human-machine readable collaborative models and tools to fill the existing wide gaps in the Lepidoptera diversity studies, especially in biodiversity-rich areas. The integration of historic human-created knowledge with technological achievements based on Artificial Intelligence, Machine Learning, and Machine Modelling could advance and improve significantly the quality of research on Lepidoptera diversity and interlinked fields. In this way, the symposium could equip the attendees with solutions to address the present-day problems in research that have a broader societal impact.
On the GeV excess in the diffuse γ-ray emission towards the Galactic Center

description: The Fermi-LAT γ-ray data have been used to study the morphological and spectral features of the so-called GeV excess - a diffuse radiation component recently discovered towards the Galactic centre. We used the likelihood method to analyze Fermi-LAT data. Our study does confirm the existence of such an extra component in the diffuse γ-ray emission at GeV energies. Based on a detailed morphological analysis, a spatial template that fits the data best was generated and adopted. Using this template, the energy distribution of γ-rays was derived in the 0.3-30 GeV energy interval. The spectrum appeared to have less distinct ('bump'-like) structure than previous reported. We argue that the morphology of this radiation component has a bipolar rather than a spherically symmetric structure as has been assumed a priori in previous studies. This finding excludes the associations of the GeV excess with Dark Matter. We briefly discuss the radiation mechanisms and possible source populations that could be responsible for this new component of diffuse gamma radiation.

description: In this note we study the geometric wakefields generated by a driving electron bunch in the SPARC LAB COMB chamber. Due to the change in iris radius of the beam pipe leading into the chamber, the electron beam will induce wakefields, which can have an effect on the bunches in the train used for the SL COMB experiment. Here, we present wakefields and impedances simulations and determine the effects that they may have on the beam properties.

Phegea52-1. 18-6. Innovative technological solutions to accelerate the systematics of mega-diverse insect orders
Creators: name: De Prins, Jurate
Publisher: name: figshare
Year: 2024
Subjects: classificationCode: 310913
subject: Invertebrate biology

description: In the current situation of a biodiversity crisis, we look for a more holistic and integrative way to address the ongoing problems and find influential solutions in traditional research fields such as insect systematics and phylogeny. Lepidoptera as the most studied, loved and collected insect group provides endless possibilities to integrate the visual, bionomical, genomic, and distribution/observation data into a broader pattern of machine-readable models and approaches that help to understand the complexity of evolutional processes, especially in the Global South. Within the proposed symposium we aim to invite speakers that have already made a significant contribution in creating human-machine readable collaborative models and tools to fill the existing wide gaps in the Lepidoptera diversity studies, especially in biodiversity-rich areas. The integration of historic human-created knowledge with technological achievements based on Artificial Intelligence, Machine Learning, and Machine Modelling could advance and improve significantly the quality of research on Lepidoptera diversity and interlinked fields. In this way, the symposium could equip the attendees with solutions to address the present-day problems in research that have a broader societal impact.

description: Using scalar-vector-tensor Brans Dicke (VBD) gravity [3] in presence of self interaction BD potential $V(ϕ)$ and perfect fluid matter field action we solve corresponding field equations via dynamical system approach for flat Friedmann Robertson Walker metric (FRW). We obtained 3 type critical points for $ΛCDM$ vacuum de Sitter era where stability of our solutions are depended to choose particular values of BD parameter $ω.$ One of these fixed points is supported by a constant potential which is stable for $ω<0$ and behaves as saddle (quasi stable) for $ω\geq0.$ Two other ones are supported by a linear potential $V(ϕ)\simϕ$ which one of them is stable for $ω=0.27647.$ For a fixed value of $ω$ there is at least 2 out of 3 critical points reaching to a unique critical point. Namely for $ω=-0.16856(-0.56038)$ the second (third) critical point become unique with the first critical point. In dust and radiation eras we obtained 1 critical point which never become unique fixed point. In the latter case coordinates of fixed points are also depended to $ω.$ To determine stability of our solutions we calculate eigenvalues of Jacobi matrix of 4D phase space dynamical field equations for de Sitter, dust and radiation eras. We should be point also potentials which support dust and radiation eras must be similar to $V(ϕ)\simϕ^{-\frac{1}{2}}$ and $V(ϕ)\simϕ^{-1}$ respectively. In short our study predicts that radiation and dust eras of our VBD-FRW cosmology transmit to stable de Sitter state via non-constant potential (effective variable cosmological parameter) by choosing $ω=0.27647$.

Configuration interaction relativistic Hartree-Fock model

Subjects: subject: Nuclear Theory (nucl-th)

description: The configuration interaction relativistic Hartree-Fock (CI-RHF) model is developed in this work. Compared to the conventional configuration interaction shell model (CISM), the CI-RHF model can be applied to study the structural properties of a wide range of nuclei without readjusting any parameters, as the effective Hamiltonian for different model space can be deduced consistently from a universal density-dependent Lagrangian based on the Hartree-Fock single-particle basis. The convergence of intermediate-state excitations has been examined in evaluating the effective interactions, and the core-polarization effects are illustrated, by using $^{18}$O as an example. Employing the CI-RHF model, both the bulk properties and low-lying spectra of even-even nuclei $^{18\sim 28}$Ne have been well reproduced with the model space restricted to the $sd$ shell. Studies of the isotopic evolution concerning charge radii and low-lying spectra highlight the shell closure at $N=14$ for neon isotopes. Furthermore, the cross-shell calculations extending from the $sd$ to $pf$ shell successfully reproduced the low-lying spectra of $^{30}$Ne and $^{32}$Ne. Notably, remarkably low excitation energies $E(2^{+}_{1})$ of $^{30}$Ne suggest the disappearance of the conventional magicity $N=20$.

description: How does the alchemy of the dissertation work? In order to explore the question underlying Umberto Eco's well-known volume How a thesis is done (Eco [1977] 2017) and to have the undergraduates themselves grapple with the problems of method underlying the choice of thesis topic and supervisor, the Research Lab of Architectural Design and Visual and Narrative drawing towards the Thesis Project held at the Iuav in Venice as part of the Master Degree Course of Architecture, proposed to the students to make a game/toy inside a box, starting from the construction of the hypothesis for the thesis in architecture and then from the collection of the first documentary and bibliographical data; one of the critical points for the lecturer was not to overlap with the actual supervision provided by the thesis supervisor.
