A multidimensional approach to echoing
Authors: Lozano-Palacio Inés 
Published: February 2023

Abstract
Stemming from the use-mention distinction by the philosophy of language, Relevance Theory introduces the notion of echo in the context of the echoic mention theory of irony (cf. Wilson & Sperber, 2012). Since then, echoing has awakened multidisciplinary interest, mostly in connection to this figure of thought. Studies on echoing have provided a largely one-dimensional approach. Within cognitive modeling studies, echoing is elevated to the status of cognitive operation. Taking cognitive modeling as a starting point, the aim of the present article is to study echoing from a multidimensional perspective, focusing on its features, functions, and usages. Specifically, the present study addresses echoic implicitness, completeness, complexity, accuracy, and non-ironic echoes (i.e., parodic echoes, denotational and non-denotational echoes). All in all, this study introduces a higher degree of systematicity in the study of echoing in general and endows echo-based studies of irony with greater explanatory adequacy.
Initial release condition dependent decoupling motion of a Wilberforce pendulum in the case of near resonance
Authors: Zeng Linqian , Li Haonan , Xie Yifan , Pan Wei 
Published: February 2023

Abstract
The vertical and angular oscillation of a Wilberforce pendulum was found to be coupled in the case of resonance. Many studies have discussed the effects of the physical properties of a Wilberforce pendulum on coupled motion. In this article, we mainly study the influence of initial release conditions on the coupled motion of a Wilberforce pendulum in the near resonance case. The experimental results clearly exhibit that the coupled motion phenomenon depends on the initial release condition. Theoretical calculation further demonstrates that the coupled strength between two normal modes is determined by the ratio of initial angular to vertical displacement in the case of near resonance. The experimental results also verify the calculated variation of decoupling coefficient with this displacement ratio. Our study indicates that even in the case of resonance, the motion of a Wilberforce pendulum is probably decoupled at a given initial release condition. Complete decoupled motion is found to appear only when the damping coefficients in vertical and angular motion generate equal energy dissipation rates. The corresponding decoupling phenomenon in the case of resonance, occurs when the initial release energy of vertical and angular motion is equal.

Abstract
A theoretical study of the dipole photoelectron angular distribution asymmetry parameter, β, of the 6s, 5s and 4s subshells has been conducted for a range of closed-shell heavy, Hg (Z = 80), Rn (Z = 86), Ra (Z = 88) and superheavy, No (Z = 102), Cn (Z = 112), Og (Z = 118), Ubn (Z = 120) elements to understand the deviation of β from the nonrelativistic value of 2 owing to relativistic effects. It was found that the deviation, strongest in Cooper minimum regions, persists over all energy for all ns subshells, and the deviations increase with Z. Three levels of relativistic calculations were performed in order to pinpoint the particular interactions responsible for the details of the behavior of the ns β’s as functions of energy, n, and Z and, in addition to the effects of the (relativistic) spin–orbit interaction, interchannel coupling was found to be of crucial importance in the determination of the β parameter in most of the situations studied.

Abstract
The fabrication of low-cost and mechanically robust flexible electronic patterns has increasingly gained attention due to their growing applications in flexible displays, touch screen panels, medical devices, and solar cells. Such applications require cost-effective deposition of metals in a well-controlled manner potentially using nanoparticles (NPs). The presence of solvent and precursors in NP based inks impacts the electrical conductivity of the printed pattern and a post-processing heating step is typically performed to restore the electrical properties and structure of the material. We report printing with picolitre droplet volumes of silver (Ag) NPs on flexible substrates using an acoustic microdroplet dispenser. The low-cost, controlled deposition of Ag ink is performed at room temperature on photopaper, polyimide and clear polyimide substrates. A localized, ultrashort pulsed laser with minimal heat affected zone is employed to sinter printed Ag patterns. For comparison, oven sintering is performed, and the results are analysed with scanning electron microscopy, four-point probe and Hall measurements. The femtosecond laser sintering revealed highly organized, connected nanostructure that is not achievable with oven heating. A significant decrease in sheet resistance, up to 93% in Ag NPs on clear polyimide confirms the laser sintering improves the connectivity of the printed film and as a result, the electrical properties are enhanced. The surface morphology attained by the laser sintering process is interpreted to be due to a joining of NPs as a result of a solid-state diffusion process in the near surface region of NPs.

Abstract
Magneto-thermal-acoustic imaging with magnetic nanoparticles (MNPs) is a novel medical imaging modality based on the thermoacoustic (TA) effect of MNPs. We proposed a new dual-modality imaging strategy that combines the TA and echo signals. Based on the synthetic aperture method, we used TA signals to image cancer tissues labeled with MNPs and applied echo signals to achieve tissue structure imaging. In the simulation, we constructed a breast cancer model and assumed that cancer tissue was labeled with MNPs. Under a limited field of view, the TA and echo signals were collected using a multi-element transducer array. By fusing the imaging results of the TA and echo signals, we obtained a boundary distribution map of the breast cancer model, and accurately located the tumor tissue. In this experiment, we built a multi-channel acquisition system. Pork tissue labeled with MNPs was used as the breast cancer phantom. We collected a total of 120 TA and echo signals at 1 mm intervals using a multi-element transducer array and faithfully imaged the boundary distribution map of the phantom. Compared with the traditional linear back projection method based on focused transducers, we demonstrated that the proposed method not only improves the lateral resolution of the image, but also makes accurate cancer identification easier. This provides a promising medical imaging technology for clinical applications.
Extended analytical solutions of the Bohr Hamiltonian with the sextic oscillator: Pt-Os isotopes
Authors: Baid S , Lévai G , Arias J M 
Published: January 2023

Abstract
The sextic oscillator adapted to the Bohr Hamiltonian has been used to describe even Pt and Os isotopes from A = 188 to 198 and A = 186 to 192, respectively. The purpose of this study was to investigate the possible transition from the γ-unstable to the spherical vibrator shape phases. In this setup the potential appearing in the Bohr Hamiltonian is independent from the γ shape variable, and the physical observables (energy eigenvalues, B(E2)) can be obtained in closed analytical form within the quasi-exactly solvable formalism for the model space containing 30 of the lowest-lying levels. Experimental energy levels have been associated with the theoretical ones. The available electric quadrupole transition data (B(E2), decay preferences) have been taken into account in matching the experimental and theoretical levels. Special attention has been paid to transitions from the first two excited 0+ levels to the

= 0+ bands have been analysed. The trajectory determined by the fitted parameters in the two-dimensional phase space has also been plotted, and it has been found that all the nuclei are characterized by a deformed potential minimum, except for the heaviest Pt isotope (198Pt), for which the transition to the spherical shape phase is realised. Although the spectroscopic information on the next isotopes of the chains (200Pt and 194Os) is far less complete, there are indications that these nuclei are also close to or fall within the domain of spherical potential minimum.

Published: February 2023

Abstract
Hydraulic system operation reliability (HSOR) can evaluate time series state reliability for hydraulic system fault diagnosis and provide condition based maintenance decisions. The quick access recorder (QAR) flight data and normal values of the hydraulic system are utilized to analyze time series HSOR by calculating the operation reliability index. Considering the relationship of the hydraulic subsystem among the components, hydraulic components Bayesian Network is constructed to analyze time series HSOR. Furthermore, the sensitivity of HSOR features to fault location is assessed using categorical boosting (CatBoost) and Shapley Additive ex-Planations values. Through the analysis of two flights hydraulic system QAR datasets, it is revealed that (a) HSOR can accurately monitor the time series operating states of the hydraulic system; and (b) with demonstrating two illustrative case, the HSOR values and features sensitivity analysis can be a useful reference for the fault diagnosis and location of the airplane hydraulic system. The study intends to develop a practical reference approach for hydraulic system fault diagnosis and location using QAR data.
Hierarchical graph neural network with adaptive cross-graph fusion for remaining useful life prediction

Published: February 2023

Abstract
Multi-sensor monitoring data provide abundant information resources for complex machine systems, which facilitates monitoring the degradation process of machinery and ensuring the reliability of the industrial process. However, previous prognostic methods focus more on the sequential data obtained from multi-sensors, while ignoring the underlying prior structural information of the equipment. To fully leverage the structural information into the modeling process, and thus improve the remaining useful life (RUL) prediction performance, a hierarchical graph neural network with adaptive cross-graph fusion (HGNN-ACGF) method for RUL prediction is proposed in this study. In the HGNN-ACGF method, a hierarchical graph consisting of a sensor graph and a module graph is constructed by introducing the structural information to fully model the degradation trend information of the complex machine system. Besides, the graph neural network (GNN) is adopted to learn the representation at both the module graph and sensor graph, and an adaptive cross-graph fusion (ACGF) block is proposed. Owing to the cross-graph fusion block, the representation from different graphs can be fused adaptively by considering the relative importance between different modules and sensors. To verify the proposed method, the experiments were conducted on a set of degradation data sets of aircraft engines provided by the Commercial Modular Aero-Propulsion System Simulation. The experimental results show that the proposed method has superior performance in RUL prediction over the state-of-the-art methods.

Abstract

Purpose. Although charged particle therapy (CPT) for cancer treatment has grown these past years, the use of protons and carbon ions for therapy remains debated compared to x-ray therapy. While a biological advantage of protons is not clearly demonstrated, therapy using carbon ions is often pointed out for its high cost. Furthermore, the nuclear interactions undergone by carbons inside the patient are responsible for an additional dose delivered after the Bragg peak, which deteriorates the ballistic advantage of CPT. Therefore, a renewed interest for lighter ions with higher biological efficiency than protons was recently observed. In this context, helium and lithium ions represent a good compromise between protons and carbons, as they exhibit a higher linear energy transfer (LET) than protons in the Bragg peak and can be accelerated by cyclotrons. The possibility of accelerating radioactive 8Li, decaying in 2 α-particles, and 8He, decaying in 8Li by β
− decay, is particularly interesting. Methods. This work aims to assess the interest of the use of 8Li and 8He ions for therapy by Monte Carlo simulations carried out with Geant4. Results. It was calculated that the 8Li and 8He decay results in an increase of the LET of almost a factor 2 in the Bragg peak compared to stable 7Li and 4He. This results also in a higher dose deposited in the Bragg peak without an increase of the dose in the plateau region. It was also shown that both 8He and 8Li can have a potential interest for prompt-gamma monitoring techniques. Finally, the feasibility of accelerating facilities delivering 8Li and 8He was also discussed. Conclusion. In this study, we demonstrate that both 8Li and 8He have interesting properties for therapy. Indeed, simulations predict that 8Li and 8He are a good compromise between proton and 12C, both in terms of LET and dose.
Effect of reduced geometric dimensions on torque generation in two plate rotor magnetorheological brake with in-house magnetorheological fluid
Authors: Kariganaur Ashok Kumar , Kadam Shubham , Kumar Hemantha , Arun M 
Published: February 2023

Abstract
The present study is aimed to evaluate the torque generation capacity of a two plate rotor magnetorheological (MR) brake using in-house prepared MR fluid. The prepared MR fluids were studied for sedimentation rate at different temperatures and flow characterization at different currents and at specific temperatures. The yield stress of the fluid is explored through Herschel–Bulkley model. The results depict significant increase in sedimentation rate and decrease in yield stress with increase in temperature of the MR fluid. MR brake (model-1) is fabricated after finite element method magnetics exhibit magnetic field of approximately 0.145 T in the shear gap than other two models (model-2 and model-3) considered in this study. Characterization of the MR brake illustrates that there is an increase in torque with increasing current. Further tests have been carried out to identify the effect of sedimentation on torque generation at 52 °C after 15 h of sedimentation. The results indicate 16% reduction in the initial torque because of settling of particles. MR fluid and particles characterization illustrates that 322 °C and 400 °C are critical points in controlling the MR fluid input parameters.
Confinement induced frustration in a one-dimensional

Published: February 2023

Abstract
Coupling dynamical charges to gauge fields can result in highly non-local interactions with a linear confining potential. As a consequence, individual particles bind into mesons which, in one dimension, become the new constituents of emergent Luttinger liquids (LLs). Furthermore, at commensurate fillings, different Mott-insulating states can be stabilized by including nearest-neighbour (NN) interactions among charges. However, rich phase diagrams expected in such models have not been fully explored and still lack comprehensive theoretical explanation. Here, by combining numerical and analytical tools, we study a simple one-dimensional

lattice gauge theory at half-filling, where U(1) matter is coupled to gauge fields and interacts through NN repulsion. We uncover a rich phase diagram where the local NN interaction stabilizes a Mott state of individual charges (or partons) on the one hand, and an LL of confined mesons on the other. Furthermore, at the interface between these two phases, we uncover a highly frustrated regime arising due to the competition between the local NN repulsion and the non-local confining interactions, realizing a pre-formed parton plasma. Our work is motivated by the recent progress in ultracold atom experiments, where such simple model could be readily implemented. For this reason we calculate the static structure factor which we propose as a simple probe to explore the phase diagram in an experimental setup.

Published: January 2023

Abstract
Wake field excitation by a train of the laser pulses is an attractive branch of the laser wake field acceleration (LWFA). In this paper, we first discuss analytical formalism for constructing uniform and non-uniform train of laser pulses from a chirped laser pulse in the Michelson interferometer. Afterward, special criteria for resonance generation of wake field with the laser multi-pulses (MP-LWFA) are discussed numerically. We show that in the nonlinear regime of the laser wake field, a non-uniform train of laser pulse can be attractive in maintaining the resonance condition. For large laser amplitudes, 3 < a
0 < 10 (a

= eE/mcω), the optimized non-uniform train of laser pulses shows >30% increase in the acceleration gradient compared to the uniform train of laser pulses.

Published: January 2023

Abstract
Based on optical medium analogy, we establish a formalism to describe the interaction between an electromagnetic (EM) system with gravitational waves (GWs) background. After a full discussion on the classical treatment of the EM-GW interaction and finding the EM field mode-functions in the presence of the magneto-dielectric media caused by GWs, the governing quantum interaction Hamiltonian is obtained. Investigation of the optical quadrature variance as well as the visibility of a laser field interacting with the multi-mode squeezed primordial gravitational waves imply that the inflationary primordial gravitational waves (PGWs) act as a decoherence mechanism that destroy EM coherency after a characteristic time scale, τ

Quantum information masking of an arbitrary unknown state can be realized in the multipartite lower-dimensional systems
Authors: Shang Wei-Min , Fan Xing-Yan , Zhang Fu-Lin , Chen Jing-Ling 
Published: January 2023

Abstract
Quantum information masking is a protocol that hides the original quantum information from subsystems and spreads it over quantum correlation, which is available to multipartite except bipartite systems. In this work, we explicitly study the quantum information masking in multipartite scenario and prove that there exists an universal quantum masker can mask the information encoding in the unknown states into a multipartite system with lower-dimensional local systems, namely, all the k-level quantum states can be masked into a m-qudit systems (m ≥ 4) whose local dimension d ≤ k . In order to observe the masking process intuitively, explicitly controlled operations are provided. Our scheme well demonstrates the abundance of quantum correlation between multipartite quantum system and has potential application in the security of quantum information processing.

under the influence of retarded free stream velocity and decreasing surface temperature along with body contour and surface transverse curvature. With the use of such retarded velocities and body contour the similarity of flow phenomenon does not sustain, and the problem becomes non-similar in nature which has been solved using an efficient numerical scheme, commonly known as Keller-Box. The effects of pertinent parameters such as exponent of free stream velocity m, exponent of surface temperature q, body contour n, and surface transverse curvature k on temperature profile, rate of heat transfer at the surface, and energy thickness of thermal boundary layer are presented through various graphs and tables. The rate of heat transfer and the energy thickness of the thermal boundary layer are observed to decrease with increasing levels of retardation. Furthermore, the rate of heat transfer decreases as the body contour parameter increases, whereas the surface transverse curvature parameter exhibits the opposite trend.

Abstract
The equations of motion in the transition layer of a free-electron laser of the relativistic strophotron type are studied. Two types of strophotrons are considered: electric and magnetic. It is shown, that the condition of a suddenly switching-on interaction: smallness of the transition layer at the entrance compared to the distance traveled by the electron in longitudinal direction in one period of transverse oscillations in strophotron is realistic and feasible.
