Désambiguïsation et description lexicographique des formules expressives de la conversation
Authors: Grossmann Francis , Krzyżanowska Anna 
Published: April 2023

Résumé
Certaines recherches lexicographiques pionnières telles que celles parues dans le tome IV du Dictionnaire
explicatif combinatoire du français contemporain (Mel’čuk et al. 1999) avaient proposé un traitement
formalisé de quelques unités polylexicales préfabriquées fréquemment mobilisées dans les échanges informels. De la même manière,
les expressions au centre de notre étude sont des formules expressives, utilisées couramment dans la
conversation. L’étude se propose de préciser comment il est possible d’analyser leur polyfonctionnalité, c’est-à-dire la diversité
de leurs fonctions illocutoires et de leurs rôles interactionnels, en précisant le type d’indices (co-occurrents lexicaux,
structures syntaxiques) permettant la désambiguïsation. Les formules ont été sélectionnées à partir d’un critère de fréquence,
dans la base orale ORFEO, avec en complément des exemples issus des réseaux sociaux. Après avoir analysé les problèmes posés par
la désambiguïsation pragmatique, nous proposons, à travers les exemples de bon courage et tu
m’étonnes, une démarche méthodologique reposant sur la notion de cadre pragmatique.
Ce que les phraséologismes nous apprennent sur la parole en contextede soins

Résumé
Notre contribution s’appuie sur la notion de phraséologisme pour analyser des interactions à l’hôpital. Il s’agit de faire ressortir l’impact des situations d’entretiens et l’importance des rôles sociaux des locuteurs dans un corpus (DECLICS2016) constitué d’échanges verbaux entre un patient et un médecin et entre un patient et un psychanalyste. L’étude de ces situations différenciées permet de repérer certaines spécificités dans les usages des participants.
L’emploi d’expressions à fonction métalinguistique (quand vous dites [ça], ça veut dire) et des « familles » de constructions incluant un modal (je peux (pas) dire) reflèterait d’éventuelles difficultés ou contribuerait au contraire à optimiser les échanges entre le patient et le professionnel de santé.
Phraséologie
Authors: Martin Philippe

RésuméLes mots, groupes de mots et phrases n’existent que par leur réalisation effective dans la parole, spontanée ou préparée, orale ou silencieuse. Ce processus implique l’intonation, qui détermine la structure prosodique de la phrase, définie comme regroupement en plusieurs niveaux des unités prosodiques minimales que sont les groupes accentuels. Les groupes accentuels sont constitués de groupes de mots terminés par une seule syllabe accentuée non emphatique, en position finale en français. Dans cette optique, les phrases préfabriquées apparaissent comme des séquences syntaxiquement toutes faites ne présentant aucune relation de dépendance syntaxique ou prosodique avec les unités syntaxiques ou prosodiques voisines. Trois exemples tirés du corpus spontané français ORFEO illustrent cette propriété.
The three-dot sign in language contact
Authors: Labrenz Annika , Wiese Heike , Pashkova Tatiana , Allen Shanley 
Published: April 2023

Abstract
In this study, we investigate the three-dot sign as a discourse marker (DM) with textual, subjective and intersubjective discourse functions. As a graphical marker that is used across languages, the three-dot sign is especially suitable for comparative studies and dynamics in language contact. Our corpus study targeting instant messages of different languages (English, German, Greek, Russian, Turkish) and speaker groups (monolinguals and bilingual heritage speakers) suggests that graphical DMs are prone to cross-linguistic influence. This depends on the specific contact situation and does not seem to be a general effect of bilingualism. The societal status of a language might further influence the use of such markers in digital informal writing. Language-specific developments that relate to emerging functions indicate that functional versatility promotes frequent use of (graphical) DMs.
Between placeholder and filler
Authors: Hennecke Inga , Mihatsch Wiltrud 
Published: April 2023

Abstract
French truc and machin (‘thing’) can function as placeholders, fillers or in
general extender constructions. The aim of our paper is to investigate whether the prosodic characteristics of these three
different uses may give a clue as to their respective status. For our analysis, we extracted 112 occurrences of
truc and 57 occurrences of machin from the audio data of the PFC Corpus, which were analysed
using Praat, focusing on the acoustic duration, the individual pitch contour and the integration of machin and
truc into the intonation contour of the utterance. As in previous studies, our results show that the prosodic
patterns vary remarkably and show a highly heterogeneous picture so that the use of prosodic properties as cues for disambiguation
is problematic. However, we are able to show some weak tendencies which point to a close functional link between placeholders and
fillers reflecting their pragmatic functions. There is no evidence for prosodic weakening or even phonetic reduction in
placeholders. Furthermore, we detect some evidence for the detachment typical of pragmatic markers in the case of fillers. The
prosodic characteristics of truc and machin in general extender constructions diverge from both
the placeholder and the filler functions. Their prosody seems to be largely determined by the particular respective construction into which
both forms are strongly integrated.
Self-help and masculinity
Authors: Krendel Alexandra 
Published: April 2023

Abstract
This study investigates the interactional norms of a manosphere discussion forum known as The Red Pill
(TRP), and asks whether it can be conceptualised as a self-help group. 2104 posts and comments from regular users and
high-status users in the community were analysed qualitatively to determine how the community is characterised by certain speech
acts, and how these speech acts correspond to face-enhancement and face-threat as well as to certain impression management
strategies.
Since personal disclosure, advice-giving, and face-enhancement are key characteristics of TRP, it
could be argued that TRP shares some functional characteristics with self-help communities. However, much of the
advice given is unsolicited, a disproportionately high rate of face-enhancement is directed towards high-status users, and speech
acts such as elaborating, and some advice-giving and personal disclosure seem to be used for self-promotion purposes. Furthermore,
the prevalence of unhedged face-threats sets TRP apart from traditional supportive communities.
Seismic noise characterisation at a potential gravitational wave detector site in Australia
Authors: Satari Hamid , Blair Carl , Ju Li , Blair David , Zhao Chunnong , Saygin Erdinc , Meyers Patrick , Lumley David 
Published: April 2023

Abstract
A critical consideration in the design of next-generation gravitational wave detectors is the understanding of the seismic environment that can introduce coherent and incoherent noise of seismic origin at different frequencies. We present detailed low-frequency ambient seismic noise characterisation (0.1–10 Hz) at the Gingin site in Western Australia. Unlike the microseism band (0.06–1 Hz) for which the power shows strong correlations with nearby buoy measurements in the Indian Ocean, the seismic spectrum above 1 Hz is a complex superposition of wind induced seismic noise and anthropogenic seismic noise which can be characterised using beamforming to distinguish between the effects of coherent and incoherent wind induced seismic noise combined with temporal variations in the spatio-spectral properties of seismic noise. This also helps characterise the anthropogenic seismic noise. We show that wind induced seismic noise can either increase or decrease the coherency of background seismic noise for wind speeds above 6 m s−1 due to the interaction of wind with various surface objects. In comparison to the seismic noise at the Virgo site, the secondary microseism (0.2 Hz) noise level is higher in Gingin, but the seismic noise level between 1 and 10 Hz is lower due to the sparse population and absence of nearby road traffic.
On causality conditions in de Sitter spacetime
Authors: Bittermann Noah , McLoughlin Daniel , Rosen Rachel A 
Published: April 2023

Abstract
We carefully consider the Shapiro time delay due to black holes and shockwaves in de Sitter spacetime and study the implications for causality. We discuss how causality conditions of AdS and flat spacetime can be applied in de Sitter spacetime, using spatial shifts measured on the boundary to define ‘fastest null geodesics’ and taking into account the ‘stretching’ of the de Sitter Penrose diagram. We consider the propagation of a massless spin-1 field with a non-minimal coupling in a de Sitter shockwave background as an illustrative example. We also briefly discuss connections to the average null energy condition.
On the dielectric properties of bisphenol A and F epoxy resins blends based on molecular dynamics
Authors: Wang Y F , Du B X , Kong X X , Li Fan , Lin Xin 
Published: April 2023

Abstract
Bisphenol A and F epoxy resins are often used as the primary insulation in power equipment. This paper investigates the influence of network structure on the dielectric properties of bisphenol A, bisphenol F epoxy resin and their blends. The results show that substituting isopropyl with methylene in epoxy resin enhances the molecular chain packing efficiency, thus limiting the polarization effect while reducing glass transition temperature (T
g). As the content of bisphenol F resin in the blends increases, the polarization loss of the blends continues to decrease, to even lower than that of bisphenol F resin. For the blend containing 20% bisphenol F resin, the T
g and AC breakdown strength at high temperatures are higher than that of bisphenol A resin. Furthermore, based on molecular dynamics simulation, the reason for the limited polarization effect of the blends is further discussed.
Excitation wavelength-dependent ultrafast THz emission from surface and bulk of three-dimensional topological insulators
Authors: Nivedan Anand , Kumar Sunil 
Published: April 2023

Abstract
Three-dimensional topological insulators possess various interesting properties that are promising for various modern applications, including in the recently emerging fields of ultrafast THz photonics and spintronics. Their gapless spin-momentum-locked topological surface states with the presence of chiral spin structure are relevant for the development of light helicity-sensitive THz emitters and detectors. In this paper, we report femtosecond excitation pulse wavelength and helicity-dependent response of Bi2Te3 and Bi2Se3 for an enhanced broadband THz pulse emission from the surface and bulk states. Specifically, the excitation wavelength has been varied in a large range from near UV to near IR, where it was observed that the photoexcitation at shorter wavelengths enhances the THz emission from both the surface and bulk states but more rapidly from the surface states. These results will be highly relevant for developing chirality-sensitive efficient THz emitters and detectors.
High sensitivity mercury ion fiber optic sensor based on Mach–Zehnder interference
Authors: Jin Xuemei , Pan Dongmei , Pan Jingshun , Huang Xuguang 
Published: April 2023

Abstract
This paper proposes a novel optical fiber sensor for highly sensitive Hg2+ detection based on Mach–Zehnder interference (MZI) structure and thiophene–chitosan hydrogel (TCH). We obtained the MZI structure by splicing the coreless fiber (CLF), thin core fiber, and CLF. And then, we etched the thin-core optical fiber cladding and assembled the TCH to produce a Hg2+ sensitive sensor. According to theoretical derivation and experimental verification, the detection sensitivity of the sensor to Hg2+ can reach 1.008 × 1011 mol l−1, and the detection limit is 5 × 10−13 mol l−1. The sensor also has performance stability within 24 h for concentration measurement, with an average standard deviation of 3.2 × 10−13 mol l−1 within an hour of observation. In addition, the sensor has the advantages of specificity, simple preparation, and low cost, and it is suitable for monitoring the concentration of Hg2+ in complex water systems.

dimensional space-time, where the space part is considered to correspond to the Beltrami pseudosphere which belongs to the family of surfaces with negative constant Gaussian curvature. We found that different parameters of deformation along one direction translate into an enhancement of the optical conductivity peaks and polarization magnitude in the far-infrared frequencies. This allows for a very high degree of polarization with a single layer graphene and opens up a potential prospect of employing graphene layer as efficient polarizers. Therefore the experimental predictions related to the electronic configuration of the corresponding graphene-like sample may be explicitly worked out.
Multi-task neural network blind deconvolution and its application to bearing fault feature extraction

Published: April 2023

Abstract
Blind deconvolution (BD) is an effective method to extract fault-related characteristics from vibration signals. Previous researches focused on two primary approaches to improve the robustness and effectiveness of BD methods: developing new optimization functions or devising new methods for estimating filter coefficients. However, these methods often suffer from the difficulty of finding the global optimum due to the complex non-convex functions. To address this issue, we propose a novel multi-objective criterion, combining two well-established sparsity criteria: kurtosis and

norm, that evaluates signal characteristics in both the time and frequency domains. We observe that this criterion, consisting of two sparsity criteria with opposite monotonicity, can mutually constrain and avoid overfitting that occurs with single-domain optimization. Inspired by multi-task convolutional neural networks, we introduce a multi-task 1DCNN with two branches to optimize the criterion in both domains simultaneously. To our best knowledge, it is the first time a multi-task convolutional neural network is used for BD problems. Experiments show that our method outperforms other state-of-the-art BD methods.

An enhanced instantaneous angular speed estimation method by multi-harmonic time–frequency realignment for wind turbine gearbox fault diagnosis
Authors: Li Cheng , Wang Yi , Zhang Guangyao , Qin Yi , Tang Baoping 
Published: April 2023

Abstract
Gearboxes are one of the most critical transmission devices in wind turbines (WTs). Order tracking (OT) of variable-speed WT gear is a powerful means to carry out fault diagnosis. Since it is difficult to install a tachometer or encoder for gearboxes with limited structural space, it is impossible to obtain the instantaneous angular speed (IAS) of the gearbox. In recent years, many tacholess techniques have been presented to estimate instantaneous phase from vibration signals for OT. However, their performance needs to be further improved to get a more exact diagnosis result. To solve this issue, this paper presents an enhanced IAS estimation approach for WT tacholess order tracking (TLOT), which is available for accurate IAS estimation of the rotating shaft, so that TLOT can be more effectively conducted under conditions of large speed variation and background noise. An improved cost function algorithm is designed to extract the IAS from the vibration signal. A Vold–Kalman filter and Hilbert transform are combined to calculate the instantaneous phase. Afterwards, the raw non-stationary vibration signal is resampled at an equal angle increment, and the envelope order spectrum is calculated from the resampled signal for fault diagnosis of the WT gearbox. The main innovating idea of this approach is to improve the traditional cost function ridge-extraction method by introducing gradient information based on probability and multi-harmonic time–frequency realignment, which makes the IAS estimation process more accurate and overcomes the limitations of traditional IAS estimation techniques. The effectiveness of the presented approach is demonstrated by using a vibration signal measured from real-world WT gearboxes, and the validation results demonstrate that the presented approach surpasses some state-of-the-art methods in IAS estimation accuracy and efficiency.
2D analytical modelling of asymmetric junctionless dual material double gate MOSFET for biosensing applications considering steric hindrance issue
Authors: Basak Arighna , Deyasi Arpan , Sarkar Angsuman 
Published: April 2023

AbstractThe current manuscript for Asymmetric Junctionless Dual Material Double Gate MOSFET (AJDMDG MOSFET) biosensor reports improved sensitivity for both threshold voltage and ON-current. In the presence of high-K dielectric material, the device was built using both neutral and charged biomolecules. After calculating the minimal surface potential, the threshold voltage is calculated by solving the 2D Poisson’s equation using a parabolic-potential configuration under realistic boundary circumstances. Analytical results show good agreement with TCAD simulation, prompting an exploration of threshold voltage sensitivity with front-gate voltage changes of all possible dimensions. Corresponding drain current sensitivity with a higher ON-to-OFF current ratio is theoretically estimated and compared with identical DGFET architecture, resulting in a significant improvement for all possible step patterns when steric hinderance is considered for moderately filled cavities; this aids in detecting both labelled and label-free electrical species at lower concentration levels.
First principle study of electronic and optical properties of WS2(1-x)Se2x obtained by isoelectronic Se substitution on S-site of monolayer WS2
Authors: Saha Ajoy Kumar , Gupta Partha Sarathi , Rahaman Hafizur 
Published: April 2023

Abstract
Two-dimensional semiconducting transition metal dichalcogenides have recently grabbed attention among the researchers, due to their extraordinary electrical, optical and thermal properties. Also, they have shown their suitability for application in digital electronics, photovoltaic cells, Thermoelectric generators and so on. Still, it is desired to precisely control the material properties to expand their scope of application and revamp the device performance. The substitutional doping technique is one of the widely explored processes, which is conventionally used to modulate the material properties. In the present work, the substitutional doping of selenium at the sulfur site within the WS2 sheet, is used indigenously to improve the electrical and optical response of the material. In doing so, electrical and optical properties of such doped materials are studied by employing density functional theory and linearized Boltzmann transport equation by considering the relaxation time approximation. The study has shown an almost linear variation of electronic band gap energy with the doping percentages. Also, the electron and hole mobility were found to be tailored due to the doping. Notably, hole mobility has shown a noticeable improvement at or near 60 percent of selenium doping. In the last section of the current work, the optical properties are extracted for the doped structures. The WS2 monolayer has shown the highest absorption peak near 3 eV. But for the doped materials, absorption peaks are relatively smaller and left shifted in the energy axis due to their low band gap energies.
Probing axions via light circular polarization and event horizon telescope
Authors: Shakeri Soroush , Hajkarim Fazlollah 
Published: April 2023

Abstract
The impact of axion-like particles on the light polarization around the horizon of supermassive black hole (SMBH) is discussed in the light of the latest polarization measurement of the Event Horizon Telescope
(EHT). We investigate different sources of the polarization due to axion interaction with photons and the magnetic field of SMBH. These can modify the linear and circular polarization parameters of the emitted light. We have shown that a significant circular polarization can be produced via the photon scattering from the
background magnetic field with axions as off-shell particles. This can further constrain the parameter space of ultralight axion-like particles and their couplings with photons. The future precise measurements of circular
polarization can probe the features of ultralight axions in the near vicinity of SMBH.
Self-interacting gravitational atoms in the strong-gravity regime

Published: April 2023

Abstract
We numerically investigate free and self-interacting ultralight scalar fields around black holes in General Relativity. We focus on complex scalar fields Φ whose self-interactions are described by the quartic potential V ∝ λ |Φ|4, and ignore the black hole spin in order to disentangle the effects of self interactions on the boson cloud. Using the spectral solver Kadath, we compute quasi-equilibrium configurations of the dominant eigenstates, including their backreaction on the spacetime metric. For scenarios with -10-2 ≲ λ ≲ 10-2 we find the mass of the self-interacting scalar cloud to be up to ∼ 70% larger than that of a free scalar cloud, though the additional backreaction effect on the spacetime metric is only up to ∼ 1% due to the low-density nature of the bosonic configurations. In this region of parameter space we observe approximate quadratic scalings between the mass of the cloud with λ, the scalar field amplitude, and the couplings between these two parameters. For systems with λ beyond this range, the eigenfrequencies differ sufficiently from the known free-test-field values used as inputs in our numerical setup
to make the results, though convergent, physically unreliable.
This bounds the range of λ in which the free scalar field solution remains a good approximation to self-interacting scalar field configurations. Our work is among the first nonperturbative explorations of self-interacting bosonic clouds around black holes, yielding detailed new insights into such systems in the nonlinear regime, while also overcoming technical challenges and quantifying limitations. Additionally, our results provide useful inputs
for fully dynamical numerical relativity simulations and for future explorations of spinning black holes and real scalar fields.
Search for stochastic gravitational-wave background from string cosmology with Advanced LIGO and Virgo's O1∼O3 data
Authors: Jiang Yang , Fan Xi-Long , Huang Qing-Guo 
Published: April 2023

Abstract
String cosmology models predict a relic background of gravitational-wave (GW) radiation in the early universe. The GW energy spectrum of radiated power increases rapidly with the frequency, and therefore it becomes a potential and meaningful observation object for high-frequency GW detector. We focus on the stochastic background generated by superinflation in string theory and search for such signal in the observing data of Advanced LIGO and Virgo O1∼O3 runs in a Bayesian framework. We do not find the existence of the signal, and thus put constraints on the GW energy density. Our results indicate that at f = 100 Hz, the fractional energy density of GW background is less than 1.7 × 1-8 and 2.1 × 10-8 for dilaton-string and dilaton only cases respectively, and further rule out the parameter space restricted by the model itself due to the non-decreasing dilaton and stable cosmology background (β bound).
