Differences in syntactic annotation affect retrieval
Authors: Zehentner Eva , Hundt Marianne , Schneider Gerold , Röthlisberger Melanie 
Published: May 2023

AbstractPrepositional phrases (PPs) play an important part in English argument structure constructions, but pose considerable challenges for linguistic investigations of any kind. In addition to the fact that PP-attachment is generally notoriously difficult to model computationally, a particularly striking methodological challenge in investigating verb-dependent PPs across (synchronic and/or diachronic) corpora is that such cross-corpus studies may have to rely on material annotated with different tools. This study evaluates the impact that such differences in corpus annotation may have on retrieval of verb-attached PPs by means of data from Early and Late Modern English corpora. Our intrinsic (recall/precision) and extrinsic parser evaluation shows that annotation does play a role, but that the noise introduced is negligible as far as frequency developments are concerned.
Dealing with missing participants in the opening phases of a videoconference
Authors: Hoffmann Sabine , Fele Giolo 
Published: May 2023

Abstract
The paper explores the social interaction that takes place during the initial phases of videoconferences. The
focus is on the problem of absent participants, which is often considered a reason for delaying the official beginning of the
meeting. One of the resources that the participants have is to reach the absent participant by cellphone. We observed a recurrent
pattern of action whereby one of the participants disengages from the video meeting to reach the missing person by phone. This
negotiation process moves through four steps: (1) the detection of the problem, (2) the offer to call the missing person by one
participant, (3) the acceptance of this offer by the moderator, and (4) the temporary absence of the participant from the video
meeting to make the phone call. Our data concern videoconferencing in the context of international teacher training in German as a
foreign language (LEELU project, https://www.leelu.eu/english/).
Metarepresentational phenomena in Japanese and English
Authors: Uchida Seiji 
Published: May 2023

AbstractContrastive studies of languages usually focus on differences in lexical items, syntactic structures, semantic expressions, collocations, and so on. In the present paper we take a cognitive pragmatic approach, assuming that metarepresentation in the sense ofSperber (2000)andWilson (2000)offers a crucial perspective in such studies. We discuss how the speech act component of higher-level explicatures is linguistically realized in Japanese and English, focusing on sentence adverbials, ‘because’ clauses, speech act particles, reported speech, private predicates, and desiderative predicates. We conclude that in the Japanese language, information concerning the speech act component tends to be linguistically realized, while such information is not necessarily realized in English. We suggest that this cognitive pragmatic approach can be applied to other languages where higher-level explicatures are basically explicit as in Japanese or implicit as in English.
Dog owners: Disenfranchised guilt and related depression and anxiety
Authors: Kogan Lori R. , Bussolari Cori , Currin-McCulloch Jennifer , Packman Wendy , Erdman Phyllis 
Published: May 2023

Abstract
Parental guilt, one common subtype of guilt often associated with work-family conflict (WFC), has been found to be associated with depression and anxiety. Because many people view their pets as family members and even children, the current study was designed to explore dog owners’ dog-related guilt and its relationship with depression and anxiety. Through an online anonymous survey, the results of our study suggest that dog owners’ guilt and dog-related WFC are at comparable levels to those reported in human family studies. They are also both significant predictors of depression and anxiety. It is important for mental health professionals to be aware of this disenfranchised guilt and help clients cope in positive ways. Guidance related to self-compassion is offered as one strategy to help pet owners struggling with this common, but often trivialized, source of guilt.

Abstract
Companion animals, including pet dogs, can be sources of support and potentially contribute to children’s competence and adjustment. The goal of this paper is to examine whether children’s pet dog relationships are related to their competence and adjustment after accounting for relationships with parents and friends and demographic factors. We distinguished three qualities of child-pet dog relationships – positive pet relationship qualities, friction, and pets as substitutes for people – and examined them in relation to children’s thriving, school academic performance, and internalizing and externalizing behavior problems. The sample included 115 children (M age = 10.93, 57 girls and 58 boys) who completed questionnaires about the quality of their relationship with a pet dog, the positive and negative qualities of a best friendship, and the security of attachments to parents. To measure child competence, children reported their thriving and parents reported children’s school academic performance. To measure adjustment, parents and teachers reported child internalizing and externalizing behavior problems. Positive pet relationship qualities were related to a higher competence. Friction and pets as substitutes were related to lower competence and adjustment, although some findings varied by the reporter or after controlling for other factors. Pet relationship quality uniquely contributed to some child outcomes, although moderation analyses did not provide any evidence that pet dog relationships compensate for low-quality friendships or insecure parental attachments. Collectively, the findings suggest that relationships with pets may augment but not override the impact of relationships with parents and friends.

Abstract
The transition from O3 to NO
x
discharge mode is common for air plasma with an increase of discharge power density, which greatly changes the chemistry of the plasma as well as its application effect. Although this discharge mode transition has been intensively studied in recent years, differences between plasmas subject to pulsed or sinusoidal excitations have rarely been reported on. In this study, a surface dielectric barrier discharge is excited using either a microsecond pulsed voltage or a sinusoidal voltage. The discharge mode transition of these two excitations is then comparatively studied. The results indicate that pulsed excitation produces more O3 in O3 mode discharge; the O3 concentration for pulsed excitation is 27.7% higher than that for sinusoidal excitation at the same power density of P = 0.08 W cm−2. On the contrary, it produces less NO and NO2 in NO
x
mode discharge; the NO concentration for pulsed excitation is 13.2% lower than that for sinusoidal excitation at P = 0.32 W cm−2. As a result, pulsed excitation delays the transition of the discharge mode when the discharge power density increases. This can be attributed to the higher electron and lower gas temperature of the pulse-excited plasma, which promotes O3 and inhibits NO
x
production.
Research on the surface crack detection of specimen manufactured by selective laser melting based on local singular value decomposition method

Published: May 2023

Abstract
SLM (selective laser melting) is an important additive manufacturing technology. Parts with complex structures can be produced by SLM, so surface cracks and other defects within SLM parts are difficult to be identified by traditional nondestructive testing techniques. In this paper, laser ultrasonic technology is proposed to identify the surface crack of SLM specimen. Because of the anisotropy and residual stress of the specimen, the time signal is strongly interfered with by noise, which makes the identification and location of the crack difficult. To solve this problem, the phase space was reconstructed from the time signal and analyzed by the local singular value decomposition method. According to the result of the experiment, this method can reveal the variation of the phase space and has a good effect on the identification and location of the surface crack whose depth is larger than 1 mm.

Published: May 2023

AbstractIn this article we study random tower maps driven by anergodicautomorphism. We prove quenched exponential correlations decay for tower maps admitting exponential tails. Our technique is based on constructing suitable cones of functions, defined on the random towers, which contract with respect to the Hilbert metric under the action of appropriate transfer operators. We apply our results to obtain quenched exponential correlations decay for severalnon-iidrandom dynamical systems including small random perturbations of Lorenz maps and Axiom A attractors.

Published: May 2023

Abstract
Soft gripper robots provide superior safety, adaptability, and compliance compared to rigid robots. However, soft grippers must address inadequate stiffness and interference resistance. Soft pneumatic electroadhesion (EA) grippers with variable stiffness are potential options for addressing these difficulties. In this paper, we present a soft bionic gripper (SOBG) that resembles human finger movements, such as bending and deflection, employing pneumatic actuation, and whose stiffness is effectively decoupled from its position through a layer jamming-induced variable stiffness structure. By applying electroadhesive forces, the SOBG can perform complex motion tasks that would typically require a wrist joint, making them simpler to perform than with conventional flexible grippers. In addition, the SOBG can perform one-finger object manipulation to grasp flat, concave, and convex objects. To show the potential for more complex robotic applications, we evaluated each function independently by presenting a demonstration of cap-screwing, a material handling system, and an anti-interference research. The SOBG concept and solution proposed in this study may pave the way for the easy integration of EA into soft robotic systems and promote the wider use of EA technology.
HPSA: a high-performance smart aggregate for concrete structural health monitoring based on acoustic impedance matching method
Authors: Li Xiuquan , Chen Lin , Chen Hongbing , Kong Qingzhao 
Published: May 2023

Abstract
Piezoceramic-based ultrasonic transducers have demonstrated the feasibility and effectiveness of functioning as smart aggregates (SAs) to detect damages for concrete structures in laboratory-sized structural members. The restriction of its further engineering application is the limited propagation distance due to the large energy loss during wave transmission. Aiming to reduce the energy loss of piezoceramic-based sensors, the authors proposed a high-performance piezoceramic-enabled SA based on acoustic impedance matching principle. The main contribution to the performance enhancement comes from the proposed surface treatment of the lead zirconate titanate patch and acoustic impedance matching layer. Comparative experiments with commercial SAs validate the improved performance. Besides, a field test with different wave propagation distances fully illustrates the perspective of the proposed superior transducer in large infrastructure engineering applications.
Significant improvement of the lower critical field in Y doped Nb: potential replacement of basic material for the radio-frequency superconducting cavity
Authors: Xie Wei , Liu Yu-Hao , Fan Xinwei , Wen Hai-Hu 
Published: May 2023

Abstract
The research of high energy and nuclear physics requires high power accelerators, and the superconducting radio-frequency (SRF) cavity is regarded as their engine. Up to now, the widely used practical and effective material for making the SRF cavity is pure Nb. The key parameter that governs the efficiency and the accelerating field (E
acc) of a SRF cavity is the lower critical field H
c1. Here, we report a significant improvement of H
c1 for a new type of alloy, Nb1−x
Y
x
fabricated by the arc melting technique. Experimental investigations with multiple tools including x-ray diffraction, scanning electron microscopy, resistivity and magnetization are carried out, showing that the samples have good quality and a 30%–60% enhancement of H
c1. First principle calculations indicate that this improvement is induced by the delicate tuning of a Lifshitz transition of a Nb derivative band near the Fermi energy, which increases the Ginzburg–Landau parameter and H
c1. Our results may trigger a replacement of the basic material and thus a potential revolution for manufacturing the SRF cavity.
Pulsatory patterns in active viscoelastic fluids with distinct relaxation time scales
Authors: de Kinkelder E M , Fischer-Friedrich E , Aland S 
Published: May 2023

Abstract
Developing tissues need to pattern themselves in space and time. A prevalent mechanism to achieve this are pulsatile active stresses generated by the actin cytoskeleton. Active gel theory is a powerful tool to model the dynamics of cytoskeletal pattern formation. In theoretical models, the influence of the viscoelastic nature of the actin cytoskeleton has so far only been investigated by the incorporation of one viscoelastic relaxation time scale. Here, using a minimal model of active gel theory, we show that distinct shear and areal relaxation times are sufficient to drive pulsatile dynamics in active surfaces with only a single molecular regulator.
Viscoelectric effect analysis in an electroosmotic flow with microchannel wall slip
Authors: Ramos Edgar A , Monsivais Ian G , Méndez Federico , Lizardi José J 
Published: May 2023

Abstract
In the present work, we developed a numerical analysis for an electroosmotic flow circulating in a rectangular microchannel considering electrolyte viscosity as a function of the induced electric field; which is also reflected in the slip condition imposed on the system walls, since the slip length is a function of the fluid viscosity. It should be clarified this is an entirely hydrodynamic problem, and for this reason there are no induced pressure gradients, because we are in the presence of a purely electroosmotic flow, where the fluid motion is due only to electrokinetic forces. Based on these comments, the problem is centered on high induced potentials, enabling viscoelectric effect analysis in the electroosmotic flow, which leads to significant increases in velocity and volumetric flow profiles compared to the case where the viscosity is a constant and there is no slip condition. Due to analytical analysis limitations, we implemented a dimensionless equation scheme defined by the continuity equation, the momentum equations in the x and y direction, the Poisson-Boltzmann equation, and the charge conservation equation to obtain the velocity and volumetric flow rate profiles mentioned above. This model is described in its variational form in order to implement the finite element technique using free software, FreeFem++. The results obtained show how the viscoelectric effect is relevant when working with high induced potentials; that is, for values of

Abstract
The formation of extra capacitance in Fe3O4/Li batteries can be comprehended by utilizing the in situ magnetometry method. Nevertheless, the precise mechanism behind this phenomenon remains elusive. In this study, we adopt Li
x
O8/Fe to investigate the formation process of extra capacitance in Fe3O4/Li batteries from a microscopic and quantitative viewpoint. The Fe0 atoms exhibit an enhanced capability to store extra charge during the Li16O8/Fe process, and has significantly contributes to the magnetization of the batteries. Furthermore, we provide an accurate description of the process from the storage of excess electrons to the formation of polymer films. The outcomes of our research could potentially facilitate better control over the generation of additional capacitance.
Squeezed state generation using cryogenic InP HEMT nonlinearity
Authors: Salmanogli Ahmad 
Published: May 2023

Abstract
This study focuses on generating and manipulating squeezed states with two external oscillators coupled by an InP HEMT operating at cryogenic temperatures. First, the small-signal nonlinear model of the transistor at high frequency at 5 K is analyzed using quantum theory, and the related Lagrangian is theoretically derived. Subsequently, the total quantum Hamiltonian of the system is derived using Legendre transformation. The Hamiltonian of the system includes linear and nonlinear terms by which the effects on the time evolution of the states are studied. The main result shows that the squeezed state can be generated owing to the transistor’s nonlinearity; more importantly, it can be manipulated by some specific terms introduced in the nonlinear Hamiltonian. In fact, the nonlinearity of the transistors induces some effects, such as capacitance, inductance, and second-order transconductance, by which the properties of the external oscillators are changed. These changes may lead to squeezing or manipulating the parameters related to squeezing in the oscillators. In addition, it is theoretically derived that the circuit can generate two-mode squeezing. Finally, second-order correlation (photon counting statistics) is studied, and the results demonstrate that the designed circuit exhibits antibunching, where the quadrature operator shows squeezing behavior.

Abstract
Periodic edge localized modes (ELMs) are the non-linear consequences of pressure-gradient-driven ballooning modes and current-driven peeling modes becoming unstable in the pedestal region of high confinement fusion plasmas. In future tokamaks like ITER, large ELMs are foreseen to severely affect the lifetime of wall components as they transiently deposit large amounts of heat onto a narrow region at the divertor targets. Several strategies exist for avoidance, suppression, or mitigation of these instabilities, such as the naturally ELM-free quiescent H-mode (QH-mode). In the present article, an ASDEX Upgrade (AUG) equilibrium that features a QH-mode is investigated through non-linear extended magneto-hydrodynamic simulations covering the dynamics over tens of milliseconds. The equilibrium is close to the ideal peeling limit and non-linearly develops saturated modes at the edge of the plasma. A dominant toroidal mode number of n = 1 is found, for which the characteristic features of the edge harmonic oscillation are recovered. The saturated modes contribute to heat and particle transport preventing pedestal build-up to the ELM triggering threshold. The non-linear dynamics of the mode, in particular its interaction with the evolution of the edge safety factor, are studied, and suggest a possible new saturation mechanism for the QH-mode. The simulations show good qualitative and quantitative agreement with experiments in AUG. In particular, the processes leading to the termination of QH-mode above a density threshold are studied, which results in the transition into an ELM regime. In the vicinity of this threshold, limit cycle oscillations are observed.

0.5) toroidal rotation from argon (Ar17+, 40 AMU) and molybdenum (Mo32+, 96 AMU) ions has been compared in C-Mod tokamak plasmas over a wide range of operating conditions and confinement schemes, including Ohmic L-mode in the linear and saturated regimes, ion cyclotron range of frequencies heated I-mode and H-mode, as well as in discharges with induced locked modes and with external current and rotation drive. In all cases the velocities of the two impurities are identical within about 5%, for a range between −60 and +80 km s−1. This is in general agreement with the predictions of neo-classical theory.

Published: May 2023

Abstract
This paper introduce pose-aware multi-position feature network for driver distraction recognition, taking into account the high association between the visual and geometric features of neighboring human key points. This method first uses the object detector to detect the driver’s body, and then uses the pose estimation to detect the key points of the human body. Finally, the key points of the human body are deconstructed to obtain key visual features and spatial features.In order to create the visual representation that corresponds to each key point, all the chosen visual representations are sent into a convolutional neural network. The geometric locations of key points on the upper body are used to build the spatial reasoning module, which is then transmitted to the neural network to get spatial features. The visual appearance features are fused with geometric features to predict corresponding driver action through linear layers.The experimental result shows that our methods achieve comparative performance on our own HY Large Vehicle Driver Dataset and the public AUC Driver Distracted Dataset.
