AbstractComputational analysis of infant movement has significant potential to reveal markers of developmental health. We report two studies employing dynamic analyses of motor kinematics and motor behaviours, which characterise movement at two levels, in 9-month-old infants. We investigate the effect of preterm birth (< 33 weeks of gestation) and the effect of changing emotional and social-interactive contexts in the still-face paradigm. First, multiscale permutation entropy was employed to analyse acceleration kinematic timeseries data collected from Inertial Measurement Unit (IMU) sensors on infants’ torso, wrists, and ankles (N = 32: 10 term; 22 preterm). Second, Recurrence Quantification Analysis was used to characterise patterns of second-to-second behavioural changes, from observationally coded behavioural timeseries on infants’ emotional self-regulation (N = 111: 61 term; 50 preterm). We found frequency-specific effects of context on permutation entropy. Relative to infants born at term (> 37 weeks of gestation), infants born preterm showed greater permutation entropy in their left ankle and torso movements, but not in right ankle or wrist movements. We did not find effects of preterm birth or emotional context on micro-level behavioural dynamics. Our methodology and findings inform future work using multiscale entropy to study infant development. Dynamic analysis of behaviour is a relatively young field, and applications to emotional self-regulation requires further methodological development.

AbstractPseudomonas aeruginosa is an emergent threat due to the antimicrobial resistance crisis. Bacteriophages (phages) are promising agents for phage therapy approaches against P. aeruginosa. It has been proposed that metazoans harbor phages on their mucosal surfaces, and this could be exploited for the rational design of prophylactic phage therapy. The goal of this study was to evaluate the potential of phage-mucus interaction to prevent infections caused by P. aeruginosa. We isolated two phages capable of infecting P. aeruginosa. Both are similar in morphology and closely related genetically. However, phage VAC3 is more efficient in replicating in mucin-exposed P. aeruginosa in vitro and is preferentially held in the respiratory tract of C57BL/6 mice. Pre-treatment with VAC3 phage protects mice from a lethal dose of P. aeruginosa while VAC1 does not. This shows that phages adapted to mucosal conditions have potential to be applied as prophylactic measures against an ESKAPE pathogen.
Modelling and control stability analysis of grid‐connected bifacial PV power generation systems using virtual synchronous generator technology

Published: January 2025

AbstractIn recent years, bifacial solar panels are accelerating to replace single‐side PV devices in traditional PV power generation system due to their high utilisation rate and price advantages. This makes the stability and control strategy of grid‐connected bifacial PV systems (GCBPVS) to be different from the traditional method after it is connected to the power systems. This paper fully considers each detailed module in GCBPVS using virtual synchronous generator (VSG) technology and derives the small‐signal model of the fully grid‐connected (GC) system using the linearisation method of each sub‐module. Then, it analyses the small disturbance stability and oscillation mode characteristics of GCBPVS by combining the effects of partial system parameters change on eigenvalues. Especially for the key parameters that affect the control stability of the system, this paper proposes a novel global optimisation design method of key control parameters to reform the distribution of system eigenvalues and improve the stability of GCBPVS. Finally, case simulation and result analysis show that the accuracy of the above small‐signal model is very high and the related stabilisation control method is very effective. In addition, hardware‐in‐the‐loop (HIL) experiments demonstrate that the proposed control method has strong engineering practicability and is better suitable for application.
Power oscillation suppression strategy of VSG based on finite‐time Hamiltonian method
Authors: Xiaomei Guo , Li Yonggang , Zhou Yichen 
Published: January 2025

AbstractIn order to improve the stability of the virtual synchronous generator (VSG) system and suppress the power oscillation, a power oscillation suppression strategy of VSG based on the finite‐time Hamiltonian method is proposed in this paper. Firstly, based on the traditional VSG control, the port‐controlled Hamiltonian with dissipation model for the active power closed‐loop circuit of the VSG grid‐connected inverter is established by considering additional control inputs. Secondly, a Hamiltonian finite‐time controller design method based on interconnection and damping assignment passivity‐based control is proposed to achieve finite‐time stability of the system. The Hamiltonian function is designed as a fractional power form by energy shaping, and the convergence speed of the system is accelerated by damping injection so that the system can quickly stabilize at the expected balance point. Then, the designed Hamiltonian function is taken as the Lyapunov function to analyse the system stability and calculate the convergence time of the VSG system. Finally, the simulation and hardware in the loop verification results show the effectiveness and great potential of this proposed controller in shortening the power oscillation time.
Ohmic heating in the upper atmosphere of hot exoplanets
Authors: Strugarek A. , García Muñoz A. , Brun A. S. , Paul A. 
Published: January 2025

Context. Exoplanets on close-in orbits are subject to intense X-ray and ultraviolet (XUV) irradiation from their star. Their atmosphere heats up, sometimes to the point where it will thermally escape from the gravitational potential of the planet. Nonetheless, XUV is not the only source of heating in such atmospheres. Indeed, close-in exoplanets are embedded in a medium (the stellar wind) with strong magnetic fields that can significantly vary along the orbit. Variations in this magnetic field can induce currents in the upper atmosphere, which dissipate and locally heat it up through Ohmic heating.
Aims. The aim of this work is to quantify Ohmic heating in the upper atmosphere of hot exoplanets, due to an external time-varying magnetic field, and to compare it to the XUV heating.
Methods. Ohmic heating depends strongly on the conductivity properties of the upper atmosphere. We developed a 1D formalism to assess the level and the localization of Ohmic heating depending on the conductivity profile. The formalism is applied to the specific cases of Trappist-1 b and π Men c.
Results. Ohmic heating can reach values up to 10−3 erg s−1 cm−3 in the upper atmospheres of hot exoplanets. It is expected to be stronger the closer the planet and the lower its central star mass, as these conditions maximize the strength of the ambient magnetic field around the planet. The location of maximal heating depends on the conductivity profile (but does not necessarily occurs at the peak of conductivity) and, in particular, on the existence and strength of a steady planetary field. Such extra heating can play a role in the thermal budget of the escaping atmosphere when the planetary atmospheric magnetic fields is between 0.01 and 1 G.
Conclusions. We confirm that Ohmic heating can play an important role in setting the thermal budget of the upper atmosphere of hot exoplanets and can even surpass the XUV heating in the most favorable cases. When it is strong, a corollary is that the upper atmosphere screens efficiently time-varying external magnetic fields, preventing them from penetrating deeper in the atmosphere or even within the planet itself. We find that both Trappist-1b and π Men c are likely being subjected to intense Ohmic heating.
When Endovascular Interventions for Endoleaks Fail

Published: January 2025

AbstractIn the appropriate patient population, endovascular aortic repair (EVAR) has become the standard of care for abdominal aortic aneurysms. While the initial success rates of EVAR are very high, reinterventions occur in a significant minority of patients, most of which consist of the repair of endoleaks. When indicated, such procedures are typically performed via endovascular or percutaneous approaches; however, in certain patients, these minimally invasive repairs fail. In these patients, surgical techniques can be used to treat the endoleaks. This article describes the open surgical techniques used in the repair of endoleaks where standard endovascular techniques fail.

Published: January 2025

Comprehensive Research Facility for Fusion Technology (CRAFT) is a technology development and validation platform for fusion technology in China. Neutral beam injection is one of the most important auxiliary heating and current drive methods in magnetically confined controlled fusion. Consequently, a negative ion based neutral beam injector (NNBI) testing facility with a beam energy of 400 keV is being developed in CRAFT. The core snubber, which provides an equivalent parallel resistance and inductance, will be used as the main surge suppression method for the CRAFT NNBI power supply system. In this paper, a core snubber for CRAFT NNBI based on Fe-based amorphous alloy is designed. The transmission line resistance, inductance, and capacitance of the high-voltage circuit have been considered during the design process. The snubber is made thin and long for even weight distribution while ensuring choke capacity. One of the snubber units was tested on the test bench. The test results indicate that the choke capacity of the snubber meets the requirement and can achieve significant suppression of peak ignition current and oscillation.

Spin crossover (SCO) complexes have been shown to exhibit giant mechanocaloric effects. Due to the change of magnetization at the spin crossover transition, they are also expected to show magnetocaloric effects. However, experimental studies on the magnetocaloric properties in SCOs are scarce. Here, we have studied the magnetocaloric response in the SCO complex [Fe(L)2](BF4)2, [L = 2,6-di(pyrazol-1-yl)pyridine] using pulsed magnetic fields. We show that applying a magnetic field can induce a partial transformation from the low spin to the high spin state. We directly measure the adiabatic temperature change of the transformation for different initial sample temperatures and magnetic fields and compare them with calculations using the Clausius–Clapeyron equation. While we found a large change in entropy of 70 J kg−1 K−1 at 50 T, the corresponding temperature change of 1.5 K is small due to the weak dependence of the transformation temperature on the magnetic field. Our study enhances the knowledge of caloric effects in SCO complexes, which so far have mainly focused on mechanocaloric studies.

Abstract
This linguistic ethnography investigates perspectives on effective English communication of nine English-medium
graduates employed in a multicultural high-risk industry. Our collaboration as two nuclear professionals uses an interdisciplinary
approach to examine workplace communication at a joint venture involving Emirati and Korean partners in the United Arab Emirates
(UAE) where English is seen as both a problem and a solution. The study draws on etic inputs from English-medium education (EME)
discourses linking English to employability and lingua franca communication, a concern with miscommunication in
organizational studies, and workplace sociolinguistics for conceptual tools highlighting transactional goals within workplace
communication. This study uses ethnographic interviews to generate understanding of the safety basis of workplace communication in
English in a multicultural high-risk industry. The study provides practical insights for language educators on effective
communication in a high-stakes sector where safety is a topic of talk and safety informs the development of a professional variety
of nuclear English and associated communication techniques. The study highlights safe communication practices as a feature of
workplace communication in English, provides some guidance on relevant resources from aviation English, and emphasizes the need
for further collaborations between academia and industry.
A typology of alternative questions in Chinese and other East Asian languages
Authors: Li Xinyi 
Published: January 2025

Abstract
This paper presents a typological study of the coding strategies of alternative questions (AQs) in Chinese and its
linguistic neighbours in Asia. An AQ is a type of question in which the speaker asks the hearer to decide which of two or more
alternatives holds. Previous studies have noted that some languages use a general disjunctive conjunction to connect the
alternatives while others use an AQ-dedicated conjunction, like haishi 還是 in Mandarin. Our investigation finds that this latter kind of
conjunction is preferred in southern varieties of Chinese, while some northern Chinese dialects tend to drop the conjunction and
add a modal particle to each alternative. The divergence reflects a more general picture of AQ-type distribution across and beyond
East Asia, where languages in the north and the west with OV order prefer to add a question marker to each alternative without
using conjunctions, while languages in the east and the south with VO order prefer to use a conjunction and allow the items to be
non-question-marked. In the transition zone from OV to VO, two atypical AQ types emerge in Sinitic languages. One type uses modal
particles or the copula verb shi 是 as the connector; the other type simply juxtaposes the alternatives without any marking, or adds a modal
particle or shi 是 to each
option. With data from and beyond East Asian languages, we argue that many of the AQ-dedicated conjunctions developed from
non-assertion markers in the sentence-initial position, which is more likely to happen in VO languages.
Historical linguistics, the pronunciation of Latin and teaching of classical languages
Authors: Kavčič Jerneja , Inkret Andreja 
Published: January 2025

Abstract
We present attempts at reforming the pronunciation of Latin in Slovenia, also analyzing — based on a survey on the
use of pronunciation in primary and high schools — the reasons for the lack of their success. In addition, we discuss two related
pedagogical projects that involved primary and secondary pupils. Our main conclusion is that the adherence to the traditional
pronunciation makes it necessary to readdress the issue of how a more authentic way of Latin pronunciation is to be incorporated
in the language instruction. One such attempt was made during the summer school, where we informed students about findings of
modern historical linguistics concerning the phonological system of Classical Latin. In addition, we tried to adopt these findings
in practice, by following them in reading a part of an authentic Latin text. Our results show that this approach to presenting the
classical pronunciation of Latin can be an interesting and well-received part of Latin instruction.
“Do you have a pen?” “Yes.”

Published: January 2025

Abstract
This study investigates how the cross-cultural variation between Spanish and Chinese interactional styles
influences the interlanguage pre-request sequences in Spanish produced by Chinese-speaking learners. Ninety-four university
students, including 40 Chinese learners of Spanish at intermediate and advanced levels, 24 native Spanish speakers and 30 native
Chinese speakers, performed 10-item open role-plays that elicited requests. Results revealed that learners exhibited negative
transfer concerning cross-cultural differences, but did not always make positive transfer in aspects of cross-cultural
similarities. Notably, learners and native Chinese speakers differed from native Spanish speakers in their production of the
pre-requests asking about the recipients’ availability and their responses to the pre-requests inquiring about the existence of
certain belongings. Furthermore, in comparison with native speakers, learners more frequently used the pre-requests asking for a
favor. The findings of this research highlight cultural diversity in speakers’ pre-request sequences and pragmatic transfer at the
interactional level. Additionally, the study brings attention to the issue of verbosity in intermediate and advanced learners’
sequential organization.
Bottom-up constructing of two-dimensional ferromagnets with high Curie temperature by assembling 5d transition metal atom@MnSr8 magnetic superatoms

Published: January 2025

Abstract
The development of advanced spintronic devices requires ultrathin two-dimensional (2D) ferromagnetic (FM) materials with high Curie temperature (T
C) and large out-of plane magnetic anisotropy energy (MAE). However, the number of high-T
C 2D ferromagnets synthesized through top-down experimental methods is very limited. Here, we propose a bottom-up approach for constructing 2D ferromagnets with high T
C by assembling magnetic superatoms. The MnSr9 superatom was first selected as building blocks to construct a series of 2D materials with square, triangular and hexagonal honeycomb lattices. First-principles studies show that all the MnSr9 self-assembled films are thermodynamically stable and exhibit ferromagnetism, unfortunately, they lack the necessary magnetic anisotropy. By substituting one Sr atom with a heavy 5d transition metal (5d-TM) atom, all these 5d-TM@MnSr8 clusters show enhanced stability and symmetry, and their self-assembled hexagonal honeycomb crystals exhibit significant magnetic anisotropy and enhanced ferromagnetism from 5d-TM atoms. Taking the PtMnSr8 superatom as an example, we have demonstrated these characteristics in detail, and the T
C and out-of-plane MAE of its honeycomb structure reach up to 253 K and 3.47 meV per unit cell under biaxial tensile strain. Moreover, the PtMnSr8 honeycomb structure on hexagonal boron nitride monolayer substrate exhibit further enhanced ferromagnetism (T
C
≈ 327 K) and distinctive antioxidant properties. This study highlights that assembling magnetic superatoms on suitable substrates is an effective way for constructing high-performance 2D FM materials.

Abstract

Objective. Clinical dosimetry in the presence of a 1.5 T magnetic field is challenging, let alone in case small fields are involved. The scope of this study is to determine a set of relevant correction factors for a variety of MR-compatible detectors with emphasis on small fields. Two dosimetry formalisms adopted from the literature are considered. Approach. Six small-cavity ionization chambers (from three manufacturers), four active solid-state detectors and a thermoluminescence dosimeter microcube were modeled in the EGSnrc Monte Carlo code. Phase space files for field sizes down to 1 × 1 cm2 of the Unity 1.5 T/7 MV MR-linac (Elekta, UK) were used as source models. Simulations were performed to calculate the

relevant to two different dosimetry formalisms. Two detector orientations with respect to the magnetic field were considered. Moreover, the effect of the ionization chamber’s stem length (a construction parameter) on the correction factor was investigated. Simulations were also carried out to determine whether correction factors obtained in water can be applied in dosimetry procedures involving water-equivalent solid phantoms. Main results. Under the

Correction factors determined in water are also valid in dosimetry protocols employing solid phantoms. Significance. This work substantially expands the range of available detectors that can be used in small field dosimetry, enabling more options for commissioning, beam modeling and quality assurance procedures in 1.5 T MR-Linacs. However, more studies are needed to establish a complete and reliable dataset.
A general simulation with trajectories in Heisenberg picture for quantum non-Markovian dynamics
Authors: chen xinyu , Li Wen Lin , Li Chong 
Published: January 2025

Abstract
We present a general numerical simulation method to solve non-Markovian dynamics of an open quantum system influenced by quantum Brownian motion. Based on the determined memory kernel function, this method enabling the resolution of non-Markovian dynamics for a wide range of system Hamiltonians and spectral densities. The system dynamics are described by exact integro-differential operator equations without any common approximations and they are simulated in this work by definite-number equations with stochastic initial conditions. This approach ensures the applicability of mature numerical methods and maintains computational complexity that remains largely invariant, even when dealing with more complex models. The high accuracy of our simulation is evident from a comparison with the results obtained from corresponding exact master equations, underscoring the reliability and precision of our method.
