Published: November 2022

We demonstrate a mirror position actuator that operates in a wide temperature range from room temperature to a deep cryogenic regime (10 K). We use a Michelson interferometer to measure the actuator tuning range (and piezoelectric efficiency) in the full temperature range. We demonstrate an unprecedented range of tunability of the mirror position in the cryogenic regime (over 22 μm at 10 K). The capability of controlling the mirror position in the range from few to few tens of microns is crucial for cavity-enhanced molecular spectroscopy techniques, especially in the important mid-infrared spectral regime where the length of an optical cavity has to be tunable in a range larger than the laser wavelength. The piezoelectric actuator offering this range of tunability in the cryogenic conditions, on the one hand, will enable development of optical cavities operating at low temperatures that are crucial for spectroscopy of large molecules whose dense spectra are difficult to resolve at room temperature. On the other hand, this will enable us to increase the accuracy of the measurement of simple molecules aimed at fundamental studies.

Published: November 2022

We report a combined experimental and theoretical investigation of electron–molecule interactions using pyrrole as a model system. Experimental two-dimensional electron energy loss spectra (EELS) encode information about the vibrational states of the molecule as well as the position and structure of electronic resonances. The calculations using complex-valued extensions of equation-of-motion coupled-cluster theory (based on non-Hermitian quantum mechanics) facilitate the assignment of all major EELS features. We confirm the two previously described π resonances at about 2.5 and 3.5 eV (the calculations place these two states at 2.92 and 3.53 eV vertically and 2.63 and 3.27 eV adiabatically). The calculations also predict a low-lying resonance at 0.46 eV, which has a mixed character—of a dipole-bound state and σ* type. This resonance becomes stabilized at one quanta of the NH excitation, giving rise to the sharp feature at 0.9 eV in the corresponding EELS. Calculations of Franck–Condon factors explain the observed variations in the vibrational excitation patterns. The ability of theory to describe EELS provides a concrete illustration of the utility of non-Hermitian quantum chemistry, which extends such important concepts as potential energy surfaces and molecular orbitals to states embedded in the continuum.
The role of word frequency in the L2 acquisition of variable patterns
Authors: van de Weijer Jeroen , Sloos Marjoleine , Wei Weiyun 
Published: November 2022

Abstract
Second language acquisition often involves the acquisition of stable patterns in a target language. Here we
investigate how the acquisition of a variable pronunciation pattern, viz. the pronunciation of the semisuffix -man
in professional names in English (e.g. policeman, businessman) is related to the lexical
frequency of the words concerned. The pronunciation of this suffix varies between a full vowel and a reduced one in a lexically
unpredictable manner (i.e. some words with -man tend to have schwa, others a full vowel, and still others vary
between the two). To test how the pronunciation of such words is acquired in a second language, we carried out a picture naming
experiment in which Chinese subjects were asked to pronounce them. The results show that the pronunciation of this semisuffix is
especially related to the educational status of subjects (major vs. non-major).
Metaphorical conceptualizations of cancer treatment in English and Chinese languages
Authors: Chow Mei-Yung Vanliza , Littlemore Jeannette 
Published: November 2022

AbstractCross-cultural variation in the metaphors that are employed by healthcare researchers and professionals when discussing cancer care is a potential impediment to the sharing of expertise. By identifying patterns in the metaphorical language used in these contexts, we can reveal differences in how healthcare practitioners understand cancer and its treatments, thus enabling more effective intercultural communication in the field of oncology. To this end, the use of metaphor in collocations of the word ‘treatment’ in nursing journals published in British English, mainland Chinese, and Taiwanese Chinese is compared. Our analysis reveals differences regarding the agency given to the cancer, its treatment, and the patient; the interrelatedness of different bodily functions and organs; and the emphasis that is placed on the course of treatment as a whole as opposed to its individual stages.
“Fish die of number, animals of footprints, but humans by mouths [words]!”
Authors: Haokip Pauthang 
Published: November 2022

AbstractThis paper discusses the cultural knowledge of Thadou-Kuki which constitutes one of the least explored genres of language use, with the hope that it will remain a source of information for future generation speakers and scholars. The paper provides examples of the vast pool of knowledge that lies underneath the traditional culture. It discusses two types of cultural knowledge in Thadou-Kuki, namely, material and oral culture transmitted from one generation of speakers to the other; these have not received the kind of attention that they deserve. The study shows how both material and oral culture are fast disappearing due to onslaughts from different quarters: the shift from traditional to a more sedentary lifestyle, the shift from traditional religion to Christianity, and finally the shift from traditional modes of entertainment to modern forms of entertainment. Many of the phenomena discussed in the paper apply to many of the other languages spoken in the hills of Northeast India, which are faced with similar threats.
Kwame Nkrumah’s construction of ‘the African people’ via the Unite or Perish myth
Authors: Nartey Mark 
Published: November 2022

Abstract
Employing Wodak’s discourse-historical approach, this paper examines how Ghana’s independence leader – Kwame
Nkrumah – in his creation of the Unite or Perish myth constructed ‘the African people’ in a manner in sync with populist
performance. It argues that Nkrumah’s discourse, in its focus on the formation of a Union Government of Africa as the only means
of Africa’s peace, progress, security and survival in the post-independence era, can be characterized as a form of populist
rhetoric that presupposes an antagonistic relationship between two homogeneous social groups. To this end, the paper analyzes
three discursive strategies utilized by Nkrumah in promoting anti-establishment sentiments while celebrating or valorizing ‘the
ordinary people’: nomination and predication of social actors and actions, the construction of a man of the people image and the
exploitation of familiarity and historical memory. It concludes with a discussion on the implications of the study for political
discourse analysis in terms of the interrelationship between political myth and populist performance.
Mitigating requesting acts by deaf Jordanian adults
Authors: Nahar Al-Ali Mohammed , Shatat Salsabeel M. 
Published: November 2022

Abstract
The purpose of this study is to investigate the linguistic mitigating devices that deaf Jordanian adults use when making requests. To this end, a sample of 52 people (of whom 26 were hearing and 26 were deaf) was collected through a Discourse Completion Task (DCT). It was found that the two groups of participants showed variations in the way they structured their request acts and spelled them out. This was evident in the deaf group’s obvious underuse of certain request mitigation strategies and the lexico-grammatical items mapping them; in the absence of some strategies (i.e., sweetener, promise of reward, hint, and threat); and in the underassessment of social distance, relative power, and degree of imposition. This inappropriate use of requesting acts by deaf participants is attributed to their inadequate linguistic, pragma-linguistic and socio-pragmatic competence. The study concludes with some suggestions how to improve the Jordanian educational system for the deaf.
The role of prior and actual situational context in conversational routines produced by Chinese learners of English
Authors: Wang Yuqi 
Published: November 2022

AbstractThis study aims to investigate the effects of English proficiency (EP) and study-abroad (SA) experience on routine production among 143 Chinese university English learners. The interplay of learners’ mastery of prior context (PC) and actual situational context (ASC) knowledge reflected their productive competence of routines (PCR). Participants were divided into three groups based on their EP levels and length of SA experience: high EP without SA, low EP without SA, and high EP with SA. A pilot study with 41 American native speakers was conducted to determine the target response set as the baseline. A seven-item computer-animated production task was used to elicit routines that revealed learners’ mastery of ASC and PC knowledge. The findings revealed that EP was only necessary for learners’ PC knowledge and PCR. SA experience, alongside SA and EP interaction, had a significant impact on both sides of ASC and PC knowledge, as well as learners’ overall PCR.
Situated co-operative creativity
Authors: Due Brian L. 
Published: November 2022

Abstract
A highly important societal aspect of language use are pragmatic creative acts and interactions. The ability to,
through multimodal interaction, create something new, is primordial for human sociality. In this paper, I propose a theoretical
model that enables detailed analysis of situated co-operative creative actions as these naturally emerge in interactional
situations. First, I develop the theoretical model by extrapolating from Charles Goodwin’s theory of co-operative action. I then
illustrate the model through detailed analysis of a single case where participants interact in a video-mediated robotic context.
The model is situated within ethnomethodological multimodal conversation analysis and based on video ethnographic data. This
research contributes to the field of creativity and human pragmatic action by providing an applicable model for Situated
Co-Operative Creativity, the SCOC model, which can be used for detailed analysis of everyday creativity.
Demographic Characteristics of Convicted Child Sexual Abusers in South of Sweden, Between 2013 and 2018: A Pilot Study
Authors: Stiernströmer Emelie , Väfors Fritz Marie , Mellgren Caroline , Khoshnood Ardavan 
Published: November 2022

Abstract
This study evaluates variables concerning demographic characteristics for all adult male offenders convicted of Child Sexual Abuse (CSA) aged 0–17 in Malmö, Sweden between 2013 and 2018. All convictions (n = 18) based on court documents from the District Court, the Court of Appeals and information from the Swedish Tax Agency were reviewed. A total of 30 victims were identified. Frequency analyses show that the most common features were that of a single offender, averaging 25 years old, with a non-Swedish background and a high school degree. The predominately extrafamilial CSA (i.e. committed by an acquaintance to the family) occurred in a private setting and consisted of penetrative acts. Girls averaging 13 years old were abused multiple times, under fear and pressure. Although assumptions based on these results are preliminary, they provide a clearer image of the typical circumstances under which CSA occurred within this time frame and geographical location. This study is a first attempt to construct an overview of demographic characteristics of CSA. As more data are gathered from this region, more sophisticated analyses can be conducted, providing stronger generalizations. Information of this kind may be important for research, classification of offender profiling and in case linking.
Exploring the small mass limit of stationary black holes in theories with Gauss–Bonnet terms
Authors: Fernandes Pedro G S , Mulryne David J , Delgado Jorge F M 
Published: November 2022

Abstract
In this work we examine the small mass limit of black holes (BHs), with and without spin, in theories where a scalar field is non-minimally coupled to a Gauss–Bonnet (GB) term. First, we provide an analytical example for a theory where a static closed-form solution with a small mass limit is known, and later use analytical and numerical techniques to explore this limit in standard scalar-GB theories with dilatonic, linear and quadratic-exponential couplings. In most cases studied here, we find an inner singularity that overlaps with the event horizon of the static BH as the small mass limit is reached. Moreover, since solutions in this limit possess a non-vanishing Hawking temperature, a naked singularity is expected to be reached through evaporation, raising questions concerning the consistency of these theories altogether. On the other hand, we provide for the first time in this context an example of a coupling where the small mass limit is never reached, thus preferred from the point of view of cosmic censorship. Finally, we consider BHs with spin and numerically investigate how this changes the picture, using these to place the tightest upper bounds to date on the coupling constant for the dilatonic and linear theories, with

Universal signature of quantum entanglement across cosmological distances
Authors: Brahma Suddhasattwa , Berera Arjun , Calderón-Figueroa Jaime 
Published: November 2022

AbstractAlthough the paradigm of inflation has been extensively studied to demonstrate how macroscopic inhomogeneities in our Universe originate from quantum fluctuations, most of the established literature ignores the crucial role thatentanglementbetween the modes of the fluctuating field plays in its observable predictions. In this paper, we import techniques from quantum information theory to reveal hitherto undiscovered predictions for inflation which, in turn, signals how quantum entanglement across cosmological scales can affect large scale structure. Our key insight is that observable long-wavelength modes must be part of anopen quantum system, so that the quantum fluctuations can decohere in the presence of an environment of short-wavelength modes. By assuming the simplest model of single-field inflation, and considering the leading order interaction term from the gravitational action, we derive auniversal lower boundon the observable effect of such inescapable entanglement. Although this signal is too weak for direct detection in the foreseeable future, we discuss the importance of its theoretical implications.
Radial recombination for rigid rotational alignment of images and volumes
Authors: Rangan Aaditya V 
Published: November 2022

Abstract
A common task in single particle electron cryomicroscopy (cryo-EM) is the rigid alignment of images and/or volumes. In the context of images, a rigid alignment involves estimating the inner product between one image of N × N pixels and another image that has been translated by some displacement and rotated by some angle γ. In many situations the number of rotations γ considered is large (e.g.

), while the number of translations considered is much smaller (e.g.

). In these scenarios a naive algorithm requires

operations to calculate the array of inner products for each image pair. This computation can be accelerated by using a Fourier–Bessel basis and the fast Fourier transform, requiring only

operations per image pair. We propose a simple data driven compression algorithm to further accelerate this computation, which we refer to as the ‘radial SVD’. Our approach involves linearly recombining the different rings of the original images (expressed in polar coordinates), taking advantage of the singular value decomposition (SVD) to both compress the images and optimize a certain measure of angular discriminability. When aligning multiple images to multiple targets, the complexity of our approach is

O

per image pair, where H is the rank of the SVD used in the compression above. A very similar strategy can be used to accelerate volume alignment, using a spherical harmonic based compression, which we will refer to as a ‘degree SVD’. The advantage gained by these approaches depends on the ratio between H and N; the smaller H is the better. In many applications H can be quite a bit smaller than N while still maintaining accuracy. We present numerical results in a cryo-EM application demonstrating that the radial and degree SVD can help save a factor of 5–10 or more for both image and volume alignment.

Abstract
We present the results of a National Science Foundation Project Scoping Workshop, the purpose of which was to assess the current status of calculations for the nuclear matrix elements governing neutrinoless double-beta decay and determine if more work on them is required. After reviewing important recent progress in the application of effective field theory, lattice quantum chromodynamics, and ab initio nuclear-structure theory to double-beta decay, we discuss the state of the art in nuclear-physics uncertainty quantification and then construct a roadmap for work in all these areas to fully complement the increasingly sensitive experiments in operation and under development. The roadmap includes specific projects in theoretical and computational physics as well as the use of Bayesian methods to quantify both intra- and inter-model uncertainties. The goal of this ambitious program is a set of accurate and precise matrix elements, in all nuclei of interest to experimentalists, delivered together with carefully assessed uncertainties. Such calculations will allow crisp conclusions from the observation or non-observation of neutrinoless double-beta decay, no matter what new physics is at play.
Successive phase transitions of the spin–orbit-coupled metal Cd2Re2O7 probed by high-resolution synchrotron x-ray diffraction
Authors: Hirai Daigorou , Fukui Atsuhito , Sagayama Hajime , Hasegawa Takumi , Hiroi Zenji 
Published: November 2022

Abstract
The 5d pyrochlore oxide superconductor Cd2Re2O7 (CRO) has attracted significant interest as a spin–orbit-coupled metal (SOCM) that spontaneously undergoes a phase transition to an odd-parity multipole phase by breaking the spatial inversion symmetry due to the Fermi liquid instability caused by strong spin–orbit coupling. Despite the significance of structural information during the transition, previous experimental results regarding lattice deformation have been elusive. We have conducted ultra-high resolution synchrotron radiation x-ray diffraction experiments on a high-quality CRO single crystal. The temperature-dependent splitting of the 0 0 16 and 0 0 14 reflections, which are allowed and forbidden, respectively, in the high-temperature cubic phase I (space group Fd–3m), has been clearly observed and reveals the following significant facts: inversion symmetry breaking and tetragonal distortion occur simultaneously at T
s1 = 201.5(1) K; the previously believed first-order transition between phase II (I–4m2) and phase III (I4122) at T
s2 ∼120 K consists of two close second-order transitions at T
s2 = 115.4(1) K and T
s3 ∼ 100 K; there is a new orthorhombic phase XI (F222) in between. The order parameters (OPs) of these continuous transitions are uniquely represented by a two-dimensional irreducible representation Eu
of the Oh
point group, and the OPs of phase XI are a linear combination of those of phases II and III. Each phase is believed to correspond to a distinct odd-parity multipole order, and the complex successive transitions observed may be the result of an electronic phase transition that resolves the Fermi liquid instability in the SOCM.

Published: November 2022

Abstract
In slug flow, the wetted wall fraction and liquid holdup of the liquid film section are key parameters affecting the mass transfer and radial velocity distribution of the liquid film, the friction pressure drop, the momentum transfer between the two phases, and heat transfer characteristics. A modified wetted wall fraction and liquid holdup model based on the modified apparent rough surface (MARS) model is proposed in this study, which considers the friction coefficient and shear stress on the gas–wall, liquid–wall and gas–liquid interfaces and introduced the modified average interface velocity of the liquid film. Air–water slug flow experiments were in a 50 mm diameter acrylic glass pipe equipped with a high-speed camera. The edge detection operator was optimized to obtain the wetted wall fraction and liquid holdup at the liquid film section based on image analysis technology. A comparative analysis of the model performance shows that the mean absolute percentage error (MAPE) of the wetted wall fraction model is 9.4%, and the 96.1% relative deviations are within the ±20% error band. The MAPE of the liquid holdup model is 8.04%, and 93.4% relative error is within the ±25% error band. The modified MARS model has good prediction ability for the wetted wall fraction and liquid holdup of the gas–liquid slug flow.
Siamese multiscale residual feature fusion network for aero-engine bearing fault diagnosis under small-sample condition

Published: November 2022

Abstract
Implementing condition monitoring and fault diagnosis of aero-engine bearings is crucial to ensure that aircraft operate safely and reliably. In engineering practice, the fault data for aero-engine bearings are extremely limited. However, the traditional fault diagnosis methods have two shortcomings under extremely small sample conditions: (1) they have limited diagnostic performance and generalization ability, and (2) they do not mine fault information sufficiently or efficiently. This article proposes a Siamese multiscale residual feature fusion network (SMSRFFN) for aero-engine bearing fault diagnosis under small-sample conditions to overcome the weaknesses above. In the proposed SMSRFFN, the training samples are first paired according to the matching rules to realize the expansion of the sample size. Second, a multiscale residual feature extraction network (MSRFEN) is constructed to excavate the fault features of different scales and speed up the convergence speed of the network. Then, a multiscale attention mechanism feature fusion module (MSAMFFM) is designed to achieve efficient fusion of fault features at different scales. Finally, the distance of the input sample is measured based on the fused deep feature representation to identify the fault state of the aero-engine bearing. The proposed SMSRFFN is evaluated using three bearing fault data and also compared with some state-of-the-art small-sample diagnostic methods. The experimental results demonstrate the effectiveness and superiority of the proposed SMSRFFN in mining fault information and improving diagnosis accuracy under extremely small sample conditions.
