description: This tutorial is a pedagogical introduction to recent methods of computing quantum spin entanglement witnesses from spectroscopy, with a special focus on neutron scattering on quantum spin systems. We offer a brief introduction to the concepts and equations, define a data analysis protocol, and discuss the interpretation of three entanglement witnesses: one-tangle, two-tangle, and Quantum Fisher Information. We also discuss practical experimental considerations, and give three examples of extracting entanglement witnesses from experimental data: Copper Nitrate, KCuF3, and NiPS3.

description: Partial Boolean algebra underlies the quantum logic as an important tool for quantum contextuality. We propose the notion atom graphs to reveal the graph structure of partial Boolean algebra for finite dimensional quantum systems by proving that (i) the partial Boolean algebras for quantum systems are determined by their atom graphs; (ii) the states on atom graphs can be extended uniquely to the partial Boolean algebras, and (iii) each exclusivity graph is an induced graph of an atom graph. (i) and (ii) show that the finite dimensional quantum systems are uniquely determined by their atom graphs. which proves the reasonability of graphs as the models of quantum experiments. (iii) establishes a connection between atom graphs and exclusivity graphs, and introduces a method to express the exclusivity experiments more precisely. We also present a general and parametric description for Kochen-Specker theorem based on graphs, which gives a type of non-contextuality inequality for KS contextuality.

description: The precise and safe control of heavy material handling machines presents numerous challenges due to the hard-to-model hydraulically actuated joints and the need for collision-free trajectory planning with a free-swinging end-effector tool. In this work, we propose an RL-based controller that commands the cabin joint and the arm simultaneously. It is trained in a simulation combining data-driven modeling techniques with first-principles modeling. On the one hand, we employ a neural network model to capture the highly nonlinear dynamics of the upper carriage turn hydraulic motor, incorporating explicit pressure prediction to handle delays better. On the other hand, we model the arm as velocity-controllable and the free-swinging end-effector tool as a damped pendulum using first principles. This combined model enhances our simulation environment, enabling the training of RL controllers that can be directly transferred to the real machine. Designed to reach steady-state Cartesian targets, the RL controller learns to leverage the hydraulic dynamics to improve accuracy, maintain high speeds, and minimize end-effector tool oscillations. Our controller, tested on a mid-size prototype material handler, is more accurate than an inexperienced operator and causes fewer tool oscillations. It demonstrates competitive performance even compared to an experienced professional driver.

description: KKMChh is a precision Monte Carlo program for photonic and electroweak radiative corrections to hadron scattering, implementing the amplitude-level exponentiation originally developed for electron-positron scattering at the quark level, modeling initial and final state QED radiation as well as initial-final interference to all orders in a soft-photon approximation, adding hard photon corrections through second order next-to-leading logarithm. A previous ICHEP talk introduced a matching procedure NISR (negative initial-state radiation) to match the exponentiated photon radiation from the quarks to a QED-corrected parton shower. Here, we describe its effect on forward-backward asymmetry calculations of interest for a precise determination of the electroweak mixing angle.

description: Plant storage proteins play a crucial role in seedling growth and plant survival, with diverse functions including antimicrobial and anti-cancer properties. Among these, antimicrobial peptides (AMPs) represent a significant group with various subclasses such as thionins, defensins, and cyclotides. While previous research has identified the antimicrobial activities of certain plant peptides against different pathogens, the impact of 2S albumins on protozoa remains unexplored. In this study, we investigate the effects of 2S albumins from crambe seeds on Trypanosoma cruzi, the causative agent of Chagas disease. These 2S albumins, typically small proteins rich in cysteines, have shown increasing clinical significance. Chagas disease is a parasitic illness transmitted primarily by triatomine vectors but can also occur through blood transfusion, organ transplantation, or congenitally. Our findings shed light on the potential therapeutic applications of 2S albumins against T. cruzi and contribute to the understanding of innovative approaches for parasitic disease control.

Towards Unsupervised Validation of Anomaly-Detection Models

description: Unsupervised validation of anomaly-detection models is a highly challenging task. While the common practices for model validation involve a labeled validation set, such validation sets cannot be constructed when the underlying datasets are unlabeled. The lack of robust and efficient unsupervised model-validation techniques presents an acute challenge in the implementation of automated anomaly-detection pipelines, especially when there exists no prior knowledge of the model's performance on similar datasets. This work presents a new paradigm to automated validation of anomaly-detection models, inspired by real-world, collaborative decision-making mechanisms. We focus on two commonly-used, unsupervised model-validation tasks -- model selection and model evaluation -- and provide extensive experimental results that demonstrate the accuracy and robustness of our approach on both tasks.

Honeycomb supersolid -- Dirac points and shear-instability induced crystal transitions

description: The honeycomb supersolid state is predicted to form in a dipolar Bose-Einstein condensate with a planar confining potential. Our results for its excitation spectrum reveal the gapless bands and the emergence of Dirac points at the Brillouin zone edge, manifesting as points where the second sound and transverse sound bands touch. The honeycomb supersolid has three sound speeds that we connect to its elastic parameters through hydrodynamic theory. From this analysis we find conditions where a shear instability occurs as the honeycomb rigidity disappears. This gives insight into the nonequilibrium dynamics following an interaction quench, where the honeycomb pattern melts and different crystal orders emerge.

description: This research focuses on the importance on the Millennial Generation and their perceptions of food buzzwords. Since the Millennial Generation is the largest group purchasing and preparing their own foods, the food industry is becoming dependent on their buying preferences. A survey reflected the participants’ demographics and their buying preferences based on a series of food buzzwords when they are purchasing foods. Results show the Millennial Generation prefers “local” buzzwords. As the Millennial Generation continues to purchase foods for themselves and their families, it can be expected their choices will encourage others to do the same based on their family shopping factors, social interaction, and relationship building traits.
An attempt to build a dynamical catalog of Solar System co-orbitals

Year: 2024
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: The main objective of this paper is to fully study 1:1 mean-motion resonance in the Solar System. We calculated stability points applying a resonant semi-analytic theory valid for any value of eccentricity or inclination. The location of each equilibrium point changes as the orbital elements of an object change, which led us to map the location of them. For the case of low inclination and low eccentricity we recovered the known L4 and L5 points. The three global types of orbits for this resonance; Tadpoles, Quasi-satellites and Horseshoes, vary as a function of the orbital elements, even disappearing for some cases. In order to build a catalog of real co-orbital objects, we filtered the NASA Horizons asteroids catalog inside the maximum resonant width and analyzed which objects are indeed in resonance. In total, we found 167 objects to be in co-orbital resonant motion with Solar System planets excluding Jupiter. We were able to recover all the already known objects and to confirm the resonant state of some new ones. Mercury remains to be the only planet with zero known co-orbitals and no L5 Earth Trojan has been discovered so far. Among the interesting identified orbits we highlight the one of 2021 FV1, a new Mars Quasi-satellite. Despite having circulating critical angles, we found some objects to be dynamically driven by the resonance such as 2012 QR50.

High-resolution HI mapping of nearby extremely metal-poor blue compact dwarf galaxies

description: Optical observations of Blue Compact Dwarf galaxies (BCDs) show they typically have high specific star formation rates and low metallicites. A subset of these galaxies (those with the lowest gas phase metallicities) display cometary optical morphologies similar to those found at high redshift. Whether this combination of properties predominantly arises from interactions with neighbours or accretion from the cosmic web or something else remains unclear. We used high resolution HI mapping to gain insights into the processes driving the observed properties of a sample of extremely metal poor (XMP) BCDs. We present Very Large Array B- and C-configuration HI mapping of four BCDs. For three of the targeted BCDs we also detect and map the HI in their nearby companions. In these three cases there is HI evidence for a recent flyby interaction between the BCD and a nearby companion. The HI evidence for recent interactions for these three BCDs is corroborated by our analysis of the tidal forces exerted on the BCDs by companions with available spectroscopic redshifts. For J0204-1009 we had sufficient spatial resolution to determine that it is dark matter dominated and estimate its DM halo mass to be in the range 1.2 x 10^11 to 5.2 x 10^11 solar masses. It is the most isolated BCD in our small sample, J0301-0052, which shows one of the most asymmetric HI morphologies. J0301-0052 has a similar cometary HI morphology to the BCD's optical morphology, although the HI column density maximum is projected at the end of the of the optical tail. Our HI observations suggest J0301-0052 may be undergoing a merger, while the other BCDs show evidence of a recent tidal interaction with a near neighbour. While our selection criteria favoured BCDs with companions our results are consistent with the earlier finding by other authors that most BCDs are associated with either mild tidal interactions or mergers.

description: The freely jointed chain model with reversible hinges (rFJC) is the simplest theoretical model that captures reversible transitions of the local bending stiffness along the polymer chain backbone, e.g. helix-coil-type of local conformational changes or changes due to the binding/unbinding of ligands). In this work, we analyze the bending fluctuations and the bending response of a grafted rFJC in the Gibbs (fixed-force) ensemble. We obtain a recursion relation for the partition function of the grafted rFJC under bending force, which allows, in principle, exact-numerical calculation of the behavior of a rFJC of arbitrary size. In contrast to stretching, we show that under sufficiently stiff conditions, the differential bending compliance and the mean fraction of closed hinges are non-monotonic functions of the force. We also obtain the persistence length $L_p$ of the rFJC, the moments $\langle R^2 \rangle$ (mean-square end-to-end distance), and $\langle z^2 \rangle$ (mean-square transverse deflection) for the discrete chain and take the continuum limit. The tangent vector auto-correlation decays exponentially, as in the wormlike chain model (WLC). Remarkably, the expression of $\langle R^2 \rangle$ as a function of the contour length $L$ becomes the same as that in the WLC. In the thermodynamic limit, we have calculated the exact bending response analytically. As expected, for $L\gg L_p$, the boundary conditions do not matter, and the bending becomes equivalent to stretching. In contrast, for $L_p\gg L$, we have shown the non-monotonicity of the bending response (the compliance and mean fraction of closed hinges).

description: Standard large deviation estimates or the use of the Hubbard-Stratonovich transformation reduce the analysis of the distribution of the overlap parameters essentially to that of an explicitly known random function ΦN,β on ℝM. In this article we present a rather careful study of the structure of the minima of this random function related to the retrieval of the stored patterns. We denote by m* (β) the modulus of the spontaneous magnetization in the Curie-Weiss model and by α the ratio between the number of the stored patterns and the system size. We show that there exist strictly positive numbers 0 < γα < γc such that 1) If √α ≤ γα (m*(β))2, then the absolute minima Φ are located within small balls around the points ±m*eµ , where eµ denotes the µ-th unit vector while 2) if √α ≤ γc (m*(β))2 at least a local minimum surrounded by extensive energy barriers exists near these points. The random location of these minima is given within precise bounds. These are used to prove sharp estimates on the support of the Gibbs measures.

description: Safely handling objects and avoiding slippage are fundamental challenges in robotic manipulation, yet traditional techniques often oversimplify the issue by treating slippage as a binary occurrence. Our research presents a framework that both identifies slip incidents and measures their severity. We introduce a set of features based on detailed vector field analysis of tactile deformation data captured by the GelSight Mini sensor. Two distinct machine learning models use these features: one focuses on slip detection, and the other evaluates the slip's severity, which is the slipping velocity of the object against the sensor surface. Our slip detection model achieves an average accuracy of 92%, and the slip severity estimation model exhibits a mean absolute error (MAE) of 0.6 cm/s for unseen objects. To demonstrate the synergistic approach of this framework, we employ both the models in a tactile feedback-guided vertical sliding task. Leveraging the high accuracy of slip detection, we utilize it as the foundational and corrective model and integrate the slip severity estimation into the feedback control loop to address slips without overcompensating.

description: Understanding how symmetry-breaking processes generate order out of disorder is among the most fundamental problems of nature. The scalar Higgs mode - a massive (quasi-) particle - is a key ingredient in these processes and emerges with the spontaneous breaking of a continuous symmetry. Its related exotic and elusive axial counterpart, a Boson with vector character, can be stabilized through the simultaneous breaking of multiple continuous symmetries. Here, we employ a magnetic field to tune the recently discovered axial Higgs-type charge-density wave amplitude modes in rare-earth tritellurides. We demonstrate a proportionality between the axial Higgs component and the applied field, and a 90$^{\circ}$ phase shift upon changing the direction of the B-field. This indicates that the axial character is directly related to magnetic degrees of freedom. Our approach opens up an in-situ control over the axialness of emergent Higgs modes.

We identify the possible dynamical connection between individual r-process-enhanced stars and the ultra-faint dwarf galaxy Reticulum II based on the current phase-space information for these stars and the dynamical mass-loss model of Reticulum II during its orbital motion for 11.5 Gyr of lookback time. The dynamical orbital modelling together with the chemical abundance analysis proved to be useful tools for the progenitor identification of the peculiar stars in our Galaxy. Methods. To reproduce the Reticulum II orbital mass loss, we used our high-precision N-body phi-GPU code to integrate almost 1 million stars into the system evolution inside a external Galactic potential. We also investigated the orbits of r-process-enhanced stars using the same code. Results. We present our Reticulum II dynamical modelling results in the context of the stars energies - angular momentum phase-space and phase-space overlapping of the currently observed r-process-enhanced stars with Reticulum II stellar tidal tails. Of the 530 r-stars known today, at least 93 are former members of the Reticulum II dynamical progenitor system.

description: Solar energetic particles (SEPs) associated with shocks driven by fast coronal mass ejections (CMEs) or shocks developed by corotating interaction regions (CIRs) often extend to high energies, and are thus key elements of space weather. The PUNCH mission, set to be launched in 2025, is equipped with photometric that enables 3D tracking of solar wind structures in the interplanetary space through polarized light. Tracking techniques are used to estimate speeds and speed gradients of solar structures, including speed jumps at fast shocks. We report on a strong and a robust relation between the shock speed jump magnitude at CME and CIR shocks and the peak fluxes of associated energetic particles from the analysis of 59 CME-driven shocks and 74 CIRs observed by Wind/STEP between 1997-2023. We demonstrate that this relation, along with PUNCH anticipated observations of solar structures can be used to forecast shock-associated particle events close to the Sun; thus, advancing and providing a crucial input to forecasting of SEP fluxes in the heliosphere.

description: We consider nonparametric estimation of the coefficients ai(·), i = 1,...,p , of a time-varying autoregressive process. Choosing an orthonormal wavelet basis representation of the functions ai(·), the empirical wavelet coefficients are derived from the time series data as the solution of a least squares minimization problem. In order to allow the ai(·) to be functions of inhomogeneous regularity, we apply nonlinear thresholding to the empirical coeffcients and obtain locally smoothed estimates of the ai(·). We show that the resulting estimators attain the usual minimax L2-rates up to a logarithmic factor, simultaneously in a large scale of Besov classes.

description: Abstract

Introduction: Intensive care unit (ICU) patients, especially those who are intubated with endotracheal tube and on a mechanical ventilator, are more likely to develop facial pressure ulcers. Aim: The aim of the current study was to compare the risk of facial pressure ulcers in patients who had endotracheal intubation fixed with twill tape versus dyna plaster. Materials and Methods: A descriptive research design was employed to conduct the study with 60 samples who met the inclusion criteria and were selected by a convenience sampling technique for the study. Thirty samples fixed with Twill tape were assigned to Group A, and 30 samples fixed with dyna plaster were assigned to Group B. From the first day to the fifth day, repositioning the tube and changing the fixation were done in both groups once every 24 hours. On the fifth day of intubation care, pressure ulcer risk assessment was done using the Braden Scale for predicting Pressure Sore Risk in both groups. Data were analyzed using descriptive and inferential statistics. Result: The calculated independent t-test value of 9.397 was found to be statistically significant at p < 0.05 level, which clearly infers that there was a statistically significant difference between the two fixations by Twill Tape and Dyna Plaster, with fixation by Twill Tape having a lower level of risk than the fixation by Dyna plaster. Conclusion: The study's findings conclude that there was a lower risk of developing pressure ulcers with Twill tape compared to Dyna plaster when the endotracheal tube is secured with twill tape.

description: In the presence of a transition magnetic moment between active and sterile neutrinos, sterile neutrinos could be produced by neutrino beams electromagnetically upscattering on nuclei. We study the active-sterile neutrino transition magnetic moment through this upscattering in the coherent elastic neutrino-nucleus scattering process induced by solar neutrinos. We place new limits on the transition magnetic moment-sterile neutrino mass plane using the latest data from the CDEX-10 experiment. We also provide projected sensitivities for future measurements. We observe that the projected sensitivities could cover some regions of the parameter space which were previously unexplored for the sterile neutrino mass up to $\sim$10 MeV.

description: Van der Waals magnets are an emerging material family for investigating light-matter interactions and spin-correlated excitations. Here, we report the discovery of a photo-induced state with a lifetime of 17 ps in the van der Waals antiferromagnet NiPS$_3$, which appears exclusively with resonant pumping at 1.476 eV in the antiferromagnetic state. The long-lived state comes with a negative photoconductivity, a characteristic optical response of population inversion. Our findings demonstrate a promising pathway to potentially achieve long-lived lasing at terahertz frequencies in reduced dimensions.

D4.1: Report On Youth Motivation Strategies
Creators: name: Paoli, Stefano

Publisher: name: Zenodo
Year: 2016

description: The goal of this deliverable is to present a strategy for young people engagement with environmental issues via the STEP platform. The deliverable begins with a presentation of the key project’s objective to which this deliverable answers. It then goes on providing a definition of how the term “strategy” is used in this work, in particular focusing on the elements of a strategy as composed of a diagnosis of the situation and on the definition of a guiding policy for action. The deliverable then offers a diagnosis of the situation based an analysis of materials. For the diagnosis of the situation the deliverable considers three sets of material: relevant literature on youth motivation to engage with environmental issues; a re-analysis of data gathered via qualitative interviews (conducted for Task 2.2 of STEP) and the data gathered as outcome of a cultural probe specifically conducted as part of the activities of Task 4.1. In particular, the deliverable discusses key concepts related with young people engagement with the environment identifying the notion of action over that of attitude as a possible basis for building engagement for STEP. This concept is taken further in the deliverable via the re-analysis of interviews and with the analysis of the data coming from the cultural probe. The deliverable then concludes with a number of recommendations for action to be implemented during the pilot operations of STEP.

description: This paper presents a novel approach for synthesizing control barrier functions (CBFs) from high relative degree safety constraints: Rectified CBFs (ReCBFs). We begin by discussing the limitations of existing High-Order CBF approaches and how these can be overcome by incorporating an activation function into the CBF construction. We then provide a comparative analysis of our approach with related methods, such as CBF backstepping. Our results are presented first for safety constraints with relative degree two, then for mixed-input relative degree constraints, and finally for higher relative degrees. The theoretical developments are illustrated through simple running examples and an aircraft control problem.

description: We present a matrix-free parallel scalable multilevel deflation preconditioned method for heterogeneous time-harmonic wave problems. Building on the higher-order deflation preconditioning proposed by Dwarka and Vuik (SIAM J. Sci. Comput. 42(2):A901-A928, 2020; J. Comput. Phys. 469:111327, 2022) for highly indefinite time-harmonic waves, we adapt these techniques for parallel implementation in the context of solving large-scale heterogeneous problems with minimal pollution error. Our proposed method integrates the Complex Shifted Laplacian preconditioner with deflation approaches. We employ higher-order deflation vectors and re-discretization schemes derived from the Galerkin coarsening approach for a matrix-free parallel implementation. We suggest a robust and efficient configuration of the matrix-free multilevel deflation method, which yields a close to wavenumber-independent convergence and good time efficiency. Numerical experiments demonstrate the effectiveness of our approach for increasingly complex model problems. The matrix-free implementation of the preconditioned Krylov subspace methods reduces memory consumption, and the parallel framework exhibits satisfactory parallel performance and weak parallel scalability. This work represents a significant step towards developing efficient, scalable, and parallel multilevel deflation preconditioning methods for large-scale real-world applications in wave propagation.

description: Understanding the nanoscale effects controlling the dynamics of a contact line -- defined as the line formed at the junction of two fluid phases and a solid -- has been a longstanding problem in fluid mechanics pushing experimental and numerical methods to their limits. A major challenge is the multiscale nature of the problem, whereby nanoscale phenomena manifest themselves at the macroscale. To probe the nanoscale, not easily accessible to other methods, we propose a reductionist model that employs elements from statistical mechanics, namely dynamic-density-functional theory (DDFT), in a Navier-Stokes-like equation -- an approach we name hydrodynamic DDFT. The model is applied to an isothermal Lennard-Jones-fluid with no slip on a flat solid substrate. Our computations reveal fluid stratification with an oscillatory density structure close to the wall and the emergence of two distinct regions as the temperature increases: a region of compression on the vapor side of the liquid-vapour interface and an effective slip region of large shear on the liquid side. The compressive region spreads along the fluid interface at a lengthscale that increases faster than the width of the fluid interface with temperature, while the width of the slip region is bound by the oscillatory fluid density structure and is constrained to a few particle diameters from the wall. Both compressive and shear effects may offset contact line friction, while compression in particular has a disproportionately high effect on the speed of advancing contact lines at low temperatures.
