Iconic gestures serve as primes for both auditory and visual word forms
Authors: Sánchez-Borges Iván , Álvarez Carlos J. 
Published: August 2023

Abstract
Previous studies using cross-modal semantic priming have found that iconic gestures prime target words that are related with the gestures. In the present study, two analogous experiments examined this priming effect presenting prime and targets in high synchrony. In Experiment 1, participants performed an auditory primed lexical decision task where target words (e.g., “push”) and pseudowords had to be discriminated, primed by overlapping iconic gestures that could be semantically related (e.g., moving both hands forward) or not with the words. Experiment 2 was similar but with both gestures and words presented visually. The grammatical category of the words was also manipulated: they were nouns and verbs. It was found that words related to gestures were recognized faster and with fewer errors than the unrelated ones in both experiments and similarly for both types of words.
SIOF

Published: August 2023

Abstract
The language learning outcomes of students in CLIL settings outstrip those of their peers who study the language
in stand-alone classes. Research also indicates that in some cases the language development of CLIL students lacks grammatical
accuracy, appropriate syntax, and lexical specificity. To combat this, CLIL teachers need to interweave the teaching of content
and language. This can be a complex task as the vast majority of CLIL teachers do not have specific CLIL training. The issue is
particularly complex at secondary level where teachers are content specialists. This article presents the research and theoretical
underpinnings of SIOF, a pedagogical tool that focuses on scaffolding, input, output and feedback practices in the classroom. This
tool has been developed to guide teachers in their efforts to place a more explicit focus on language. The authors discuss how
SIOF can lead to what they term a Language Sensitive Learning Environment and the development of both language proficiency and
subject knowledge.
Negotiating identities in stories of anti-Chinese racism during the COVID-19 pandemic
Authors: Stavridou Anastasia , Huang Haiyan , Schoofs Kim , Schnurr Stephanie , Van De Mieroop Dorien 
Published: August 2023

Abstract
Since the beginning of the coronavirus pandemic, there has been an upsurge of anti-Chinese racism. This paper investigates the socio-pragmatic processes through which Chinese international students in Belgium discursively deal with othering processes in the stories they tell about racist incidents during semi-structured research interviews. These processes are closely linked to various identities which are sometimes projected upon them and often take the form of the Standardised Relational Pair of victim and perpetrator. Our analysis illustrates the complexities of these multi-directional othering processes which span a continuum from merely acknowledging to challenging and rejecting. Findings not only contribute to current conceptualisations of othering, but also give a voice to those who are othered and demonstrate that they can be powerful agents who may find ways of speaking up and re-claiming agency rather than silently accepting the victim identities that are often assigned to them.
Le gérondif à l’aune de l’opposition anaphore / cataphore
Authors: Theissen Anne 
Published: August 2023

Résumé
Notre objectif est d’aborder le gérondif sous un angle inhabituel, celui de l’opposition anaphore / cataphore.
Notre analyse comportera trois parties. Dans la première, nous nous interrogerons sur la quasi-absence de la problématique
anaphore / cataphore dans les études sur le gérondif. Dans la deuxième partie, nous montrerons, en partant de
son statut de prédication lacunaire, que les lacunes présentées par un gérondif ne peuvent être comblées que par voie
« endophorique », c’est-à-dire anaphoriquement et / ou cataphoriquement. Enfin, dans la dernière partie, seront décrites les
différentes configurations anaphoriques et cataphoriques auxquelles peut donner lieu un gérondif, avec la mise en avant de celles
qui relèvent de la cataphore.
Les fonctions discursives de la cataphore
Authors: Jollin-Bertocchi Sophie 
Published: August 2023

Résumé
La cataphore contrevient au principe d’économie linguistique et implique un coût cognitif élevé, ce qui conduit à
s’interroger sur les conditions de son apparition. À partir d’un corpus issu de la base Frantext (XIXe et XXe s.), on se demande
de quelle manière le SN une chose en emploi cataphorique participe à la cohésion discursive. Les énoncés reposent
sur des constructions syntaxiques variées et divers effets de rupture discursive, et dans une série d’emplois une
chose fait l’objet d’une modalisation restrictive. L’enracinement des énoncés dans l’expression de l’intensité et de
la subjectivité expliquerait le recours à une structure peu économique, qui se rattache sémantiquement aussi bien au contexte
antérieur qu’au contexte postérieur, assurant la continuité textuelle à travers cette tension.
Lamb wave based damage imaging using an adaptive Capon method
Authors: Peng Linghan , Xu Caibin , Gao Guangjian , Hu Ning , Deng Mingxi 
Published: August 2023

Abstract
As plate-like structures are widely used in railway vehicle systems, structural health monitoring and nondestructive testing of those structures are important. The Lamb wave, as an ultrasonic guided wave propagating in plate-like structures, is an effective tool for fault diagnosis. The Capon method is widely used in Lamb wave based damage imaging due to its superior performance in suppressing background noise compared with the conventional delay-and-sum method. As the conventional Capon method is sensitive to modeling errors like the inaccuracy of the look-direction, diagonal loading is usually adopted to regularize the inverse of the covariance matrix. However, the degree of diagonal loading is related to the accuracy of the given look-direction and is hard to determine accurately. Aimed at improving the imaging quality of the conventional Capon method, an adaptive Capon method with adaptive diagonal loading is proposed. In the proposed method, the dispersion and the amplitude caused by wave diffusion are first compensated for each imaging point using the virtual time reversal technique. The correlations among the compensated waveforms after windowing are used to determine the degree of diagonal loading. In the process of regularizing the inverse of the covariance matrix, a large diagonal loading factor will be applied when the correlations among the compensated waveforms are large. As correlations are closely related to the signal phase, both the amplitude and the phase of scattering signals are utilized in the proposed method. The numerical and experimental validations on an aluminum plate are carried out to verify the effectiveness of the proposed method. The results show that compared with the conventional Capon method, the proposed method can obtain images with higher imaging quality, fewer artifacts, and lower noise.
A novel multi-frame wavelet generative adversarial network for scattering reconstruction of structured illumination microscopy
Authors: Yang Bin , Liu Weiping , Chen Xinghong , Chen Guannan , Zhu Xiaoqin 
Published: August 2023

Abstract

Objective. Structured illumination microscopy (SIM) is widely used in various fields of life science research. In clinical practice, it has low phototoxicity, fast imaging speed and no special fluorescent markers. However, SIM is still affected by the scattering medium of biological tissues, resulting in insufficient resolution of the obtained images, which limits the development of life sciences. A novel multi-frame wavelet generation adversarial network (MWGAN) is proposed to improve the scattering reconstruction capability of SIM. Approach. MWGAN is based on two components derived from the original image. A generative adversarial network constructed by wavelet transform is trained to reconstruct some complex details in the cell structure. Multi-frame adversarial network is used to obtain the inter-frame information of the image and use the complementary information of the before and after frames to improve the quality of the model reconstruction. Results. To demonstrate the robustness of MWGAN, multiple low-quality SIM image datasets are tested. Compared with the state-of-the-art methods, the proposed method achieves superior performance in both of the subjective and objective evaluation. Conclusion. MWGAN is effective for improving the clarity of SIM images. Meanwhile, the SIM images reconstructed by multiple frames improve the reconstruction quality of complex regions and allow clearer and dynamic observation of cellular functions.

Abstract

Objective. To develop real-time 4D MRI using MR signature matching (MRSIGMA) for volumetric motion imaging in patients with pancreatic cancer on a 1.5T MR-Linac system. Approach. Two consecutive MRI scans with 3D golden-angle radial stack-of-stars acquisitions were performed on ten patients with inoperable pancreatic cancer. The complete first scan (905 angles) was used to compute a 4D motion dictionary including ten pairs of 3D motion images and signatures. The second scan was used for real-time imaging, where each angle (275 ms) was processed separately to match it to one of the dictionary entries. The complete second scan was also used to compute a 4D reference to assess motion tracking performance. Dice coefficients of the gross tumor volume (GTV) and two organs-at-risk (duodenum-stomach and small bowel) were calculated between signature matching and reference. In addition, volume changes, displacements, center of mass shifts, and Dice scores over time were calculated to characterize motion. Main results. Total imaging latency of MRSIGMA (acquisition + matching) was less than 300 ms. The Dice coefficients were 0.87 ± 0.06 (GTV), 0.86 ± 0.05 (duodenum-stomach), and 0.85 ± 0.05 (small bowel), which indicate high accuracy (high mean value) and low uncertainty (low standard deviation) of MRSIGMA for real-time motion tracking. The center of mass shift was 3.1 ± 2.0 mm (GTV), 5.3 ± 3.0 mm (duodenum-stomach), and 3.4 ± 1.5 mm (small bowel). The Dice scores over time (0.97 ± [0.01–0.03]) were similarly high for MRSIGMA and reference scans in all the three contours. Significance. This work demonstrates the feasibility of real-time 4D MRI using MRSIGMA for volumetric motion tracking on a 1.5T MR-Linac system. The high accuracy and low uncertainty of real-time MRSIGMA is an essential step towards continuous treatment adaptation of tumors affected by real-time respiratory motion and could ultimately improve treatment safety by optimizing ablative dose delivery near gastrointestinal organs.
Method for comparison of data driven gating algorithms in emission tomography
Authors: Reymann M P , Vija A H , Maier A 
Published: August 2023

Abstract

Objective. Multiple algorithms have been proposed for data driven gating (DDG) in single photon emission computed tomography (SPECT) and have successfully been applied to myocardial perfusion imaging (MPI). Application of DDG to acquisition types other than SPECT MPI has not been demonstrated so far, as limitations and pitfalls of current methods are unknown. Approach. We create a comprehensive set of phantoms simulating the influence of different motion artifacts, view angles, moving objects, contrast, and count levels in SPECT. We perform Monte Carlo simulation of the phantoms, allowing the characterization of DDG algorithms using quantitative metrics derived from the data and evaluate the Center of Light (COL) and Laplacian Eigenmaps methods as sample DDG algorithms. Main results. View angle, object size, count rate density, and contrast influence the accuracy of both DDG methods. Moreover, the ability to extract the respiratory motion in the phantom was shown to correlate with the contrast of the moving feature to the background, the signal to noise ratio, and the noise in the data. Significance. We showed that reporting the average correlation to an external physical reference signal per acquisition is not sufficient to characterize DDG methods. Assessing DDG methods on a view-by-view basis using the simulations and metrics from this work could enable the identification of pitfalls of current methods, and extend their application to acquisitions beyond SPECT MPI.
Seedless hydrothermal growth of hexagonal prism ZnO for photocatalytic degradation of methylene blue: the effect of pH and post-annealing treatment
Authors: Oktapia Depi , Nurfani Eka , Wahjoedi Bambang A , Nulhakim Lukman , Kadja Granprix T M 
Published: August 2023

Abstract
In this paper, we study the effect of solution pH in the hydrothermal synthesis and post-annealing treatment on the photocatalytic performance of hexagonal prism ZnO grown without a seed layer. By varying the precursor molarity ratio, the solution obtained was 6.88 (ZnO-2), 7.00 (ZnO-1), and 7.58 (ZnO-3). The three samples show hexagonal prism ZnO with wurtzite structures based on scanning electron microscope and x-ray diffraction analysis. ZnO-1 samples could degrade methylene blue as high as 65.9% for a UV irradiation time of 5 h, better than ZnO-2 (51.80%) and ZnO-3 (57.55%). Post-annealing treatment of ZnO-1 with the best photodegradation efficiency was carried out at 200 °C (ZnO-4) and 400 °C (ZnO-5) to alter the structure. The post-annealing treatment changes the domination of crystal orientation from (002) to (100) plane. Also, the morphology of ZnO-5 changed significantly to become smaller rods with a diameter of 2.79 μm, as compared to ZnO-1 (2.83 μm) and ZnO-4 (3.12 μm). It is due to ionic rearrangements occurring at higher temperatures. The ZnO-5 sample reduces methylene blue by 82.91%, which is better than ZnO-1 (65.9%) and ZnO-4 (64.39%). Interestingly, we found a relation between smaller rod diameters and higher photocatalytic activity. The results show the importance of the solution pH and the annealing treatment in improving the photocatalytic performance of hexagonal prism ZnO without the seed layer.
A hybrid, asymmetric, linear Higgs factory based on plasma-wakefield and radio-frequency acceleration
Authors: Foster B , D’Arcy R , Lindstrøm C A 
Published: August 2023

Abstract
The construction of an electron–positron collider ‘Higgs factory’ has been stalled for a decade, not because of feasibility but because of the cost of conventional radio-frequency (RF) acceleration. Plasma-wakefield acceleration promises to alleviate this problem via significant cost reduction based on its orders-of-magnitude higher accelerating gradients. However, plasma-based acceleration of positrons is much more difficult than for electrons. We propose a collider scheme that avoids positron acceleration in plasma, using a mixture of beam-driven plasma-wakefield acceleration to high energy for the electrons and conventional RF acceleration to low energy for the positrons. We emphasise the benefits of asymmetric energies, asymmetric bunch charges and asymmetric transverse emittances. The implications for luminosity and experimentation at such an asymmetric facility are explored and found to be comparable to conventional facilities; the cost is found to be much lower. Some of the areas in which R&D is necessary to make HALHF a reality are highlighted, including estimates for the improvement required in key technologies. These range from a factor of 10 to a factor of 1000.

3D wind field profiles from hyperspectral sounders: revisiting optic-flow from a meteorological perspective
Authors: Héas P , Hautecoeur O , Borde R 
Published: August 2023

Abstract
In this work, we present an efficient optic flow algorithm for the extraction of vertically resolved 3D atmospheric motion vector (AMV) fields from incomplete hyperspectral image data measures by infrared sounders. The model at the heart of the energy to be minimized is consistent with atmospheric dynamics, incorporating ingredients of thermodynamics, hydrostatic equilibrium and statistical turbulence. Modern optimization techniques are deployed to design a low-complexity solver for the energy minimization problem, which is non-convex, non-differentiable, high-dimensional and subject to physical constraints. In particular, taking advantage of the alternate direction of multipliers methods (ADMM), we show how to split the original high-dimensional problem into a recursion involving a set of standard and tractable optic-flow sub-problems. By comparing with the ground truth provided by the operational numerical simulation of the European Centre for Medium-Range Weather Forecasts (ECMWF), we show that the performance of the proposed method is superior to state-of-the-art optical flow algorithms in the context of real infrared atmospheric sounding interferometer (IASI) observations.
Evaluation of the microstructure, thermal, and mechanical characteristics of Sn-9Zn reinforced with Ni and ZrO2 nanoparticles via vacuum melting process
Authors: Mohamed H S , Mostafa M M , Mahmoud N M , Mousa M M 
Published: August 2023

Abstract
The impact of minor additions of nickel and ZrO2 nanoparticles to eutectic Sn-9wt%Zn (SZ) prepared by vacuum melting technique was investigated. The morphologies and microstructures were carried out using an optical microscope (OM) and field emission scanning electron microscope technique (FESEM) escorted by energy dispersive x-ray spectrometry (EDX). The phase structure of the specimens was confirmed by an x-ray diffractometer (XRD). The results obtained demonstrate that small Ni addition causes a major grain refinement of β-Sn, due to the formation of the fine intermetallic compounds Ni5Zn21 and Sn3Ni4Zn3 phases and refines the formation of α- Zn lamellar phase. The melting temperature of the recently discovered solder alloys was lower than that of the eutectic Sn-Zn solders (∆Tm ∼ 28 °C) as a result of the preparation technique and the incorporation of Ni and ZrO2 nanoparticles. The tensile test showed enhanced the mechanical properties of SZ solder as a result of the addition of third elements. The experimental results showed that of all the alloys under investigation, the SZN903 alloy had the greatest UTS and YS values. The enhanced strength of the SZ-ZrO2 alloy defended the results of σ
UTS and increased the stress exponent parameters, n, by ∼20%. All solders had an activation energy Q that measured between ∼35.62 kJ mol−1 to ∼58.12 kJ mol−1 which comparable to the pipe-diffusion mechanism.

Published: August 2023

Abstract
In this work, a comprehensive investigation of the twin gate or double gate reverse T-shaped channel TFET (RT-DG-TFET) along with the heavily doped pocket at the source-channel interface is portrayed. Here the pockets have been placed in various places on the device like vertical and horizontal pockets across the source and the channel region, a pocket at the center of the source, a pocket near to tunneling junction, and an L-shaped pocket across the source-channel interface. All these structures are investigated and the pocket is doped with P-type impurities. Linearity and RF analysis are investigated using the Synopsis TCAD Sentaurus tools and compared among all these structures. The L-shaped pocket shows better results compared to others.
Controlling double optomechanically induced transparency and slow/fast light in an electro-optomechanical system via an optical parametric amplifier
Authors: Pan Guixia , Yu Gongtao , Xiao Ruijie , Zhai Chengbo 
Published: August 2023

Abstract
We investigate tunable double optomechanically induced transparency and slow/fast phenomena in a hybrid electro-optomechanical system. The hybrid system consists of an optical cavity with an optical parametric amplifier (OPA) and two charged mechanical resonators. The double optomechanical induce transparency can be exhibited by manipulating the coupling parameters of the electro-optomechanical system. Specifically, the number of transparent points and the width of transparent windows increase with an increase in the coupling constant. Furthermore, the phenomenon of double transparency is strongly influenced by the parametric gain of OPA and by the Coulomb interaction between the two mechanical oscillators. It is found that the larger parametric gain and Coulomb coupling induce an increasing width of transparency windows. Moreover, we study the slow/fast light effect associated with the rapid phase change of the transmission of probe field. Our approach provides a great flexibility for controlling double induced transparency, and has potential applications in optical information storage and optical communication.

Abstract
Water treatment of tapioka and tofu wastewater was studied. Water treatment was conducted by coagulation process by winged bean (Psophocarpus tetragonolobus) seed powder which was followed by adsorbstion by natural active zeolite. The changing of turbidity, DO and pH during water treatment were investigated. Turbidity of tapioca wastewater which was initially 798 FNU, decreased to 57 FNU. Increasing of tapioca wastewater DO value was obtained from 1.20 to 5.92 ppm. Increasing pH tapioca wastewater was also observed from 5.8 to 6.7. Similar results were obtained for tofu wastewater. Turbidity of tofu wastewater which was initially 680 FNU, decreased to 37 FNU. Increasing of tofu wastewater DO value was obtained from 1.67 to 6.61 ppm. Increasing pH tofu wastewater was also observed from 4.7 to 6.7. Results showed that the improvement qualities of tapioca and tofu wastewater was achieved which meet wastewater quality standard by Minister of Environment of the Republic of Indonesia.
