On the semiotic diversity of language
Authors: Lepeut Alysson , Beukeleers Inez 
Published: June 2023

Abstract
Language is complex in many respects. When conceived as a system that is to be analysed at all levels of
linguistic structure, it is interpreted as a static and abstract phenomenon in which the rules are disconnected from their context
of use. However, the ability to do language, construed as a fundamentally social practice grounded in our in situ
face-to-face interactions, does not exclusively rely on knowing the rules that govern the grammatical principles in a given
language, nor does it limit itself to understanding the lexical content of utterances. Language is more than that; it is
fundamentally social and inherently multimodal in that it enables all humans to create, express, and construe meaningful
utterances through their bodies. For a long time, however, linguistic theories have neglected to consider the diverse and rich
ways humans do language using their bodies. In this introduction, particular attention is paid to the different
roles the body plays across a range of distinct sign languages and contexts. In that respect, a short historical detour into the
evolutive stages of sign language research is provided first. Next, the aims and the different contributions of this volume are
outlined. Finally, some conclusions are drawn.

ABSTRACTThe effectiveness of a morning versus evening oral iron supplement strategy to increase iron stores was explored. Ballet and contemporary dancers with serum ferritin (sFer) < 50μg/L (n = 14), were supplemented daily with 105 mg elemental oral iron in either the morning (FeAM) or evening (FePM) for 8 weeks. A control group (n = 6) with sFer >50μg/L were given no supplement over the same period. Dancers’ sFer were measured at baseline and post‐intervention. Assessment of daily training load, dietary intake, and menstruation were made. A significant interaction (p < 0.001) showed the within group sFer change over the 8‐week intervention in FeAM (+25.9 ± 10.5μg/L) and FePM, (+22.3 ± 13.6μg/L) was significantly different to CON (−30.17 ± 28.7μg/L; both p = 0.001). This change was not different between FeAM and FePM (p = 0.778). sFer levels within FeAM and FePM significantly increased over the 8‐weeks; however, they significantly decreased in the CON group (all p < 0.05). Post‐intervention sFer levels were no longer different between the three groups (p > 0.05). Training load, dietary intake, and number of menstrual cycles incurred were similar between FeAM and FePM (p > 0.05). Oral iron supplementation in either the morning or evening appears equally effective in increasing sFer levels in dancers with sub‐optimal iron status.

Published: June 2023

Abstract
In this study, simple and effective solid-state and sol-gel routes are attempted to synthesize nickel manganese oxide, NiMn2O4. Structural, morphological, electrical, and electrochemical properties are investigated with calcination temperatures. X-ray diffraction (XRD) results confirm the highly crystalline cubic spinel structure with zero impurities for all samples, except NMOS_700, which indicates the presence of a slight NiMnO3 phase. Scanning electron microscope (SEM) and transmission electron microscope (TEM) micrographs confirm the formation of hexagonal shape particles of size less than <0.5 μm. At low calcination temperatures, grouped and uneven-shaped particles are observed with increased particle size. Electrical measurements depict the strong dependence of conductivities (σ
ac and σ
dc) on grain size, grain boundary, and operating temperature. All the samples exhibit conductivities between 10−8 and 10−4 S cm−1 with the varied calcination temperature. Electrochemical performances are explored via electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV), and galvanostatic charge–discharge (GCD) profiles. Sample NMOB_700 and NMOB_800 exhibit the initial discharging capacity of 1104 mAh g-1 and 1188 mAh g−1 at 100 mA g−1 current density. All the samples exhibit above 98% columbic efficiency after two initial cycles and show the reversible nature of NMO and excellent cyclability. The electrochemical results confirm that preparation methods and calcination temperature have a great impact on the grain properties of materials. Multiple oxidation states of Mn and Ni is also confirmed through the XPS study.

Abstract
A poled piezoelectric ceramic such as lead zirconate titanate (PZT) belongs to a C

∞

crystal class, with ten independent material constants. If we consider losses, all the material parameters can be represented in complex form as all the ten material parameters also have ten loss components associated with them. Therefore, a total of 20 independent material constants are required to obtain the entire model. In this work, we present a procedure for determining the complete reduced matrix of a piezoelectric ultrasonic disc transducer using one-dimensional resonance analysis in thickness and radial modes and parametric sweep using finite element analysis to numerically calculate the impedance while comparing it with the measured impedance. The objective is to obtain the material parameters that minimize the error between the measured impedance data and the numerical impedance curve without using any optimization techniques. We can follow the standard procedure of resonance analysis for radial and thickness modes and then conduct a sensitivity analysis using parametric sweeps in COMSOL to evaluate the unknown material values. In addition, we present the transform equations in reduced matrix form to evaluate the critically sensitive parameters concerning other consistent evaluated material constant sets. To validate the procedure, we used the impedance responses of two piezoelectric discs with diameter-to-thickness ratios of 25 and 22.5. The comparison between the numerical and experimental results shows an excellent agreement for electrical impedance curves.
Effect of CdSSe nanoparticles on the structural, surface roughness, linear, and nonlinear optical parameters of polyvinyl chloride films for optoelectronic applications
Authors: Soliman T S 
Published: June 2023

Abstract
Polyvinyl chloride (PVC) was used as a host matrix for different CdSSe nanoparticles (NPs) concentrations. PVC-CdSSe films were prepared by the solution-cast method, and CdSSe NPs were prepared by the hot-injection method. A scanning electron microscope attached to an EDX unit was used to identify CdSSe elements. The reinforcement of CdSSe NPs in the PVC matrix exhibits growth in CdSSe particle size due to agglomerations. PVC-CdSSe films were examined via XRD, FT-IR, and a polarized optical microscope. The roughness tester was used to measure the surface roughness parameters of the PVC-CdSSe films, which revealed the growth in film roughness with increasing the CdSSe concentration. The UV-visible spectrophotometer was used to analyze the PVC-CdSSe film’s transmission and absorption. Tauc’s model was used to evaluate the optical bandgap (Eg). The Eg was lessened from 5.45 eV for pure PVC to 4.78 eV for PVC-3wt%CdSSe film, while the Urbach energy was increased upon CdSSe NPs additive to the PVC matrix testifying to the formation of the localized states with high-density. Furthermore, an improvement in nonlinear optical parameters (estimated via the Wemple-DiDomenico model) was observed. The third-order nonlinear optical susceptibility ( χ(3)) enhanced from 4.08 × 10−15 for pure PVC to 1.91 × 10−13 for PVC-3wt%CdSSe, due to the surface plasmon oscillation of CdSSe NPs in the PVC matrix. In view of the improved optical parameters, the as-prepared PVC-CdSSe films make them a possible nominee for nonlinear optical devices.

Abstract
Wigner’s friend thought experiment is intended to reveal the inherent tension between unitary evolution and measurement collapse. Inspired by the Wigner’s friend experiment, Brukner derives a no-go theorem for observer-independent facts, focusing on two entangled observers in their respective laboratories. We construct an extended Wigner’s friend scenario, including three laboratories, namely, Alice’s laboratory, Bob’s laboratory and Charlie’s laboratory, where Alice, Bob and Charlie are standing outside the laboratories while their friends are placed inside their own laboratories. To realize this scenario, we create a universal quantum circuit, especially the circuit realization of the state evolution and measurement inside each laboratory, simple but novel. We carry out experiments on the IBM quantum computers to test the primary circuits, i.e. state preparation, state evolution and measurement inside each laboratory. Furthermore, we perform the simulation of the quantum circuit via Q# quantum programming on a classical computer.
Quantum dynamical speedup for correlated initial states
Authors: Gholizadeh Alireza , Hadipour Maryam , Haseli Soroush , Haddadi Saeed , Dolatkhah Hazhir 
Published: June 2023

Abstract
The maximal evolution speed of any quantum system can be expressed by the quantum speed limit time. In this paper, we consider a model in which the system has a correlation with the environment. The influence of the initial correlation between the system and environment on the quantum speed limit is investigated. It is shown that the appearance of non-Markovianity effects causes the speedup of quantum evolution. Moreover, we demonstrate the dependence of quantum dynamical speedup on the quantum coherence of the correlated initial state.

Abstract
The presented work shows a systematic study of the temporal characteristics of ELM events on the COMPASS divertor obtained with high temporal resolution probe measurements (∼1 μs). The resulting temporal evolution of the total ELM power on the outer target provides the values of rise (τ
rise) and decay (τ
decay) times for each single ELM event. It has been found that τ
rise values are in the range of about 50 μs–100 μs. These values are comparable to the time of the ELM parallel propagation (τ
||) given by the sound speed and the connection length between the outer midplane and the outboard divertor. This comparison indicates that the magnetic field lines in the SOL region are not significantly ergodized during the pedestal crash on COMPASS. It also implies that the peak ELM energy fluence on the outboard divertor is dominated by the ELM parallel transport, which is confirmed by a good agreement with model prediction. In addition, the values of the ratio of τ
decay and τ
rise for each ELM event fit very well to the boundaries 1.5 < τ
decay/τ
rise < 4, as already shown on JET as well as on the HL-2A tokamak, using IR measurements. The ratio does not show any clear dependence on the relative ELM energy or line averaged electron density. It was also found that the ELM energy fluence decay length (λϵ

mid) is clearly linked to this ratio.
Square ice formation in CrOCl and graphene confinement
Authors: Wang Yangjie , Chen Jige 
Published: June 2023

Abstract
The structure and thermodynamic properties of water in nanoscale confinement environment are greatly involved in the research field of material science and nanotechnology. However, a complete picture of the ordered structure formation and thermodynamics behavior of the confined water inside two parallel nanosheets with different surface atomic arrangement is still lacking. In this paper, by using molecular dynamics (MD) simulations, we study the structural variation and thermodynamics behavior for water molecules confined between two parallel CrOCl with a square surface atomic arrangement and two parallel graphene nanosheets with a hexagonal surface atomic arrangement. Square ice, with a lattice constant 2.1 and 2.0 Å, is observed inside the two parallel CrOCl and graphene nanosheets, respectively. By calculating the configuration entropy of the molecular dipoles St
, it is found that, in the CrOCl confinement, St
reaches a peak value and then is greatly reduced due to the square ice formation. On the other hand, in the graphene confinement, St
continues to grow after the square ice formation and is then reduced after reaching its peak value. Interestingly, it is found that the square ice could be stable at a higher entropy state under the external pressure than the bulk water at ambient condition. By calculating the orientational order parameters M, it shows that the conventional tetrahedral geometry of hydrogen bonding between water molecules breaks due to the square ice formation. By analyzing the average number of hydrogen bonds of water molecules Nh
, it is found that the hydrogen bond interaction of the square ice relies on the confinement environment, where Nh
is reduced in the CrOCl confinement and increased in the graphene confinement. Probability distribution functions of the dipole orientation angles between the x- or z-axis and the projection of the oxygen atoms of the water molecules are also calculated. It is observed that the square ice structure is paralleled with the x-axis (unit cell axis) in the CrOCl confinement and tilted with the x-axis (the zigzag direction of graphene) at an angle 30° in the graphene confinement. Furthermore, the square ice formation is found to be insensitive to temperature. Our result reveals the peculiar ordered structure and thermodynamics behavior of water in different nanoscale confinement environments.
Long-time correlations in a binary mixture: analysis of the nonlinearities of fluctuating-hydrodynamic equations
Authors: Bidhoodi Neeta , Das Shankar P 
Published: June 2023

Abstract
The equations of fluctuating nonlinear hydrodynamics (FNH) following the proper conservation laws are considered for a binary mixture. We focus on the density (ρ) correlations’ renormalization due to the FNH equations’ nonlinearities. The consequence of density nonlinearities treated in simplest approximations gives rise to the well-studied form of the mode coupling theory (MCT) for a two-component system. The MCT predicts a sharp ergodicity–nonergodicity transition similar to the one-component fluid in this idealized form. In the first part of the present paper, we compare the predictions of the idealized MCT model with the computer simulation results for a hard sphere mixture. We show that there is clear disagreement in long-time dynamic behaviour. Next, we consider the full set of nonlinearities in the FNH equations using a Martin–Siggia–Rose field theory. From the time reversal properties of the correlation and response function of the associated field theory, a set of fluctuation–dissipation relations (FDR) are obtained. These FDRs impose constraints on the long-time behaviour of the correlation functions. Our non-perturbative analysis considers the viability of freezing the time correlations for the two-component fluid over the longest time scale. Due to the FDR constraints arising from the

Design, modelling, and experimental validation of a self-rotating flapping wing rotorcraft with motor–spring resonance actuation system
Authors: Liu Fangyuan , Li Song , Dong Xin , Wang Ziyu , Xiang Jinwu , Li Daochun , Tu Zhan 
Published: June 2023

Abstract
Compared with traditional flapping motion, the flapping wing rotor (FWR) allows rotating freedom by installing the two wings asymmetrically, which introduces rotary motion characteristics and enables the FWR to have higher lift and aerodynamic efficiency at low Reynolds number. However, most of the proposed FWRs contain linkage mechanical transmission structures, the fixed degrees of freedom of which prohibit the wings from achieving variable flapping trajectories, limiting further optimization and controller design of FWRs. In order to fundamentally address the above challenges of FWRs, this paper presents a new type of FWR with two mechanically decoupled wings, which are directly driven by two independent motor–spring resonance actuation systems. The proposed FWR has 12.4 g of system weight and 165–205 mm wingspan. In addition, a theoretical electromechanical model based on the DC motor model and quasi-steady aerodynamic forces is established, and a series of experiments are conducted in order to determine the ideal working point of the proposed FWR. It is notable that both our theoretical model and experiments exhibit uneven rotation of the FWR during flight, i.e. rotation speed dropping in the downstroke and increasing in the upstroke, which further tests the proposed theoretical model and uncovers the relationship between flapping and passive rotation in the FWR. To further validate the performance of the design, free flight tests are conducted, and the proposed FWR demonstrates stable liftoff at the designed working point.
Efficiency at optimal performance of Brownian heat engines under double tangent constraint
Authors: Streitenberger Peter 
Published: June 2023

Abstract
The efficiency of a steady-state thermochemical Brownian heat engine is considered, where the heat flux from the hot to the cold reservoir drives particles from the lower chemical potential of the hot reservoir to the higher chemical potential of the cold reservoir, converting heat into chemical or potential energy. This model system is used to investigate the optimal performance of a Brownian heat engine under a new constraint based on a double tangent construction between the occupation number distributions of the particles in the two heat reservoirs with temperatures

Study of Vortex Effect on Vertical Axis Marine Current Turbine Arm
Authors: Amiadji  , Arief I S , Baidowi A 
Published: June 2023

Abstract
The design of a marine current turbine generator specifically in deep water with unequal seabed which requires the designer to develop a floating platform for the turbine. It creates a massive challenge in improving the mechanical system, such as the turbine arm. In order to make the monitoring and maintenance accessible, the generator must be placed on the platform’s deck. A long shaft is required to make the connection between the generator and turbine. The problems occur due to the vibration generated by the vortex around the shaft or the turbine arm. This paper aim is to investigate the vortex effect on the turbine arm and propose an advanced design to reduce its impact. The computational fluid dynamic method is approached to analyse the vortex generated by the turbine arm. The analysis compared the conventional cylindrical and the foil-shaped turbine arm. Moreover, the investigation includes force along the X-axis and Y-axis, flow, drag, lift coefficient, also fatigue lift near the turbine arm. The numerical output illustrates that the foil shaped on the turbine arm provided limited vortex and improved the performance compared to the conventional cylindrical turbine arm.

Published: June 2023

Abstract
This study aims to determine the effect of adding variations of fin stabilizers on the hydrodynamic characteristics of the ship design. It compares the hull without modification with the hull modified by a fin stabilizer on a prototype scale. The results of this study is assessed to obtain the best performance of ships with various models to be used in the design of ship realization. The research method is conducted by numerical approach, including simulation of resistance, stability, and seakeeping. The hull design references chosen are the Fast Police Boat and SMIT Patrol Boat with a Length Overall value of 1 m. The fin stabilizer uses hydrofoil type NACA-0015 with an aspect ratio of 0.7. Then the length variations are 3 cm, 4 cm, and 5 cm, with angle variations being 25°, 30°, and 35°. The results showed that adding a fin stabilizer could increase the ship’s stability. The best fin stabilizers variations are fins with a length of 5 cm and an angle of 30° for the prototype design of the Fast Police Boat hull and fins with a length of 5 cm and an angle of 35° for the prototype design of the SMIT Patrol Boat hull.
