President’s constitutional powers and public activism: a focused analysis of presidential speeches under Finland’s two presidencies
Authors: Kujanen Maarika , Koskimaa Vesa , Raunio Tapio 
Published: February 2024

AbstractChanges in formal powers of political actors like presidents are expected to impact their behavior. This study examines speeches that presidents can utilize for a variety of purposes ranging from topical reflections to new political initiatives and criticism of the government and political parties. In semi-presidential regimes, presidents are often constitutionally weaker than governments, but their popularity opens the possibility of using the public platform for swaying the minds of citizens or politicians. We analyze the tone and content of Finnish presidents’ New Year’s messages and parliamentary speeches from 1932 to 2023. To contribute to the long-standing literature on regime effects, we gauge the impact of Finland’s comprehensive constitutional reform that stripped off most powers of the presidency that was formerly considered among the strongest in Europe. The results show that presidential activity changed already in the mid-1990s when the reform was still underway, and presidents appointed since then speak systematically less about domestic policy and emphasize national unity and citizens, indicating that constitutionally weaker presidents recognize their jurisdictional limits and lean more on their role as directly elected heads of state operating above political parties.

Authors: Wang Chengliang , Chen Xiaojiao , Yu Teng , Liu Yidan , Jing Yuhui 
Published: February 2024

AbstractAmidst the global digital transformation of educational institutions, digital technology has emerged as a significant area of interest among scholars. Such technologies have played an instrumental role in enhancing learner performance and improving the effectiveness of teaching and learning. These digital technologies also ensure the sustainability and stability of education during the epidemic. Despite this, a dearth of systematic reviews exists regarding the current state of digital technology application in education. To address this gap, this study utilized the Web of Science Core Collection as a data source (specifically selecting the high-quality SSCI and SCIE) and implemented a topic search by setting keywords, yielding 1849 initial publications. Furthermore, following the PRISMA guidelines, we refined the selection to 588 high-quality articles. Using software tools such as CiteSpace, VOSviewer, and Charticulator, we reviewed these 588 publications to identify core authors (such as Selwyn, Henderson, Edwards), highly productive countries/regions (England, Australia, USA), key institutions (Monash University, Australian Catholic University), and crucial journals in the field (Education and Information Technologies, Computers & Education, British Journal of Educational Technology). Evolutionary analysis reveals four developmental periods in the research field of digital technology education application: the embryonic period, the preliminary development period, the key exploration, and the acceleration period of change. The study highlights the dual influence of technological factors and historical context on the research topic. Technology is a key factor in enabling education to transform and upgrade, and the context of the times is an important driving force in promoting the adoption of new technologies in the education system and the transformation and upgrading of education. Additionally, the study identifies three frontier hotspots in the field: physical education, digital transformation, and professional development under the promotion of digital technology. This study presents a clear framework for digital technology application in education, which can serve as a valuable reference for researchers and educational practitioners concerned with digital technology education application in theory and practice.
Kashmiri women in conflict: a feminist perspective
Authors: Zeeshan Sonia , Aliefendioğlu Hanife 
Published: February 2024

AbstractKashmiri women are diverse individuals with a wide range of origins, histories, experiences, and aspirations. Women in Kashmir are deeply entwined with the region’s complicated socio-political landscape, especially in terms of the protracted conflict in Kashmir. The living patterns of women in Kashmir are severely influenced by insurgency, militancy, and the consequent militarization of the region, as well as a wide range of socio-economic, historical, religious, and geopolitical circumstances. Kashmiri women’s day-to-day existence, safety, security, and mobility are strongly impacted by enhanced security protocols and the existence of armed personnel and militants in the region. Even though a great number of research works have been performed on Kashmir’s politics, history, philosophy, and religion, the struggles and challenges faced by women amid the conflict need to be further explored. This research aimed to comprehend and unveil the situation of Kashmiri women in the conflict zone through a comprehensive review of the existing literature on gendered violations in Kashmir, thereby emphasizing the need for the recognition of the suffering of Kashmiri women from a feminist perspective. Furthermore, the contributions of Kashmiri women activists, politicians, and feminists were highlighted, thus accentuating their role towards gender equality and sustainable peace in the region.

Authors: Yan Jun , Wu Manli , Liao Yuhan , Huang Yaxin 
Published: February 2024

AbstractThe medical workforce plays a critical role in building resilience in the medical system and society to respond to long COVID. The threat of career pressure and the proliferation of social media disinformation have combined to reduce medical workers’ occupational identity, triggering a wave of medical staff resignations all over the world. There is an urgent need to investigate the development of medical students’ occupational identity. Based on characteristics of medical students, this study builds on the Motivation-Opportunity-Ability (MOA) framework and develops a comprehensive theoretical model to illustrate the predictors of medical students’ occupational identity to find ways to stabilize the subsequent medical workforce pool. The results show that medical students’ occupational identity is affected by motivation, opportunity and ability factors. The results call for improving motivation cultivation and practice environment. The newly discovered role of media exposure not only provides a new way to enhance occupational identity, but also contributes to the follow-up exploration of the relationship between media environment and occupational identity.

Published: February 2024

Numerous scientific satellites require micronewton thrusters for compensating environmental disturbances. The mass flow control proportional valve plays a crucial role in precisely regulating the thrust. To meet the high resolution and wide range requirements of the thrusters, this paper introduces a novel proportional valve with two sets of independently controllable piezoelectric stack. One set of the piezo-stack is used to compensate the stroke loss of the valve core, mainly caused by the deformation of the valve seat. The valve sealing mechanism is carefully analyzed to reduce the stroke loss. Another set of the stack works as the primary actuator, enabling the high mass flow control resolution. Two sets of independently controlled piezoelectric stacks not only expand the range and improve the range ratio but also provide redundancy and enhance reliability. This means that the actuator can still operate at lower ranges even if one piezo-stack is damaged. The piezo-actuators are assembled using U-shaped connectors, creating a compact and space-efficient overall design. Experimental tests have been conducted to verify the performance of the valve, which demonstrated a mass flow range of 0–675 μg/s with a resolution better than 0.1 μg/s and a flow noise below 0.1 μg/s/Hz1/2 at 0.1 mHz–1 Hz.
A novel ultrasonic method for measuring minute sinusoidal displacement by network analyzer
Authors: Komatsu Yuya , Mori Shohei , Arakawa Mototaka , Kanai Hiroshi 
Published: February 2024

We developed a method for generating continuous sinusoidal displacements of an object to estimate viscoelastic parameters. However, the amplitude of the displacement caused by the ultrasonic excitation force under safe guidelines was small (a few micrometers), and it was difficult to stably measure the displacement. Therefore, to stably measure the amplitude of sinusoidal displacement as small as the order of micrometers, we proposed a novel method using a network analyzer. Ultrasonic waves were irradiated using an ultrasonic transducer to an object vibrating sinusoidally. The S parameter of the first reflected wave received from the surface of the object was measured using a network analyzer. The S parameter and the inverse Fourier transform were formulated theoretically, and the amplitude of the sinusoidal displacement of the object was estimated from the amplitude characteristics of the inverse Fourier-transformed signal. The proposed method was applied to measure sinusoidal displacements on the order of micrometers from 10 to 300 Hz on an object using a water tank experiment. The obtained sinusoidal displacement agreed well with the reference values measured using a laser displacement meter. The proposed method can accurately measure minute sinusoidal displacements that occur on an object.
Enantioselective control in chiral crystallization of ethylenediamine sulfate using optical trapping with circularly polarized laser beams

Published: February 2024

In this study, we conducted successful experiments on ethylenediamine sulfate (EDS), an organic compound, to investigate its enantioselectivity in chiral crystallization. We employed optical trapping with circularly polarized laser beams, using a continuous wave laser at 1064 nm. By focusing the laser at the air–solution interface of a heavy water-saturated EDS solution, the formation of sub-micrometer-sized chiral EDS crystals was verified. Two generated enantiomorphs (d-crystal and l-crystal) were identified by the rotating analyzer method. The enantioselectivity in the chiral crystallization of EDS was assessed through 30 to 60 times experiments conducted under various conditions of laser powers and polarization modes, utilizing the count of generated crystals for each enantiomorph in the evaluation. Circularly polarized lasers at a specific power created an imbalance in the generation probability of the enantiomorphs, resulting in crystal enantiomeric excess values of 23% and −30%. The enantioselectivity mechanism was explored from two perspectives: refractive index differences of two enantiomorphs and 3D helical optical forces. Study of the thermodynamic mechanism was insufficient to explain the outcomes. Conversely, the 3D helical optical force mechanism revealed that the forces acting on EDS clusters in solution induced helical fluid motion, driving EDS nucleation, with the helicity of fluid motion determining the crystal’s chirality. This approach will present new insights into chirality in industrial and research fields, with potential applications in regard to improving optical resolution and addressing the origin of homochirality.

Published: February 2024

Abstract
Youth lexicon has penetrated and become consolidated in the common colloquial register of adult speakers of any
given language. This study uses a comparable bilingual corpus of original Spanish and Italian series, and a parallel trilingual
corpus which includes the target Spanish and Italian versions of an analogous French series in order to investigate the use of
such voices in national and foreign serial products of both cultures. The frequency of use per minute and the repertoire of terms
inserted in the series of the two countries have been compared. The results show that the number of occurrences per minute in the
Spanish original fictional language is much higher than in the Italian one, where this kind of words and expressions are often
excluded. These data coincide with the number of occurrences per minute recorded in the Spanish and Italian target versions.
Therefore, the parallelism between the original and target products of both languages shows that hybridization and domestication
have been the predominant strategies in the translation for dubbing.
Classical-trajectory model for ionizing proton-ammonia molecule collisions: the role of multiple ionization
Authors: Jorge Alba , Horbatsch Marko , Kirchner Tom 
Published: February 2024

Abstract
We use an independent electron model with semi-classical approximation to electron dynamics to investigate differential cross sections for electron emission in fast collisions of protons with ammonia molecules. An effective potential model for the electronic orbitals is introduced, and utilized in the context of the classical-trajectory Monte Carlo (CTMC) approach for single-electron dynamics. Cross sections differential in electron emission angle and energy are compared with experimental data. Compared to previous scattering-theory based quantum-mechanical results the time-dependent semi-classical CTMC approach provides results of similar quality for intermediate and high ionized electron energies. We find some discrepancies in the total cross sections for q-fold ionization between the present model and independent-atom-model calculations. The double ionization cross sections are considerably larger than recent experimental data which are derived from coincidence counting of charged fragments. The calculated triple ionization cross sections exceed the experimental coincidence data for q = 3 by several orders of magnitude at intermediate energies.
Resonance Raman spectroscopy of twisted interfaces in turbostratic multilayer graphene
Authors: Mohapatra A , Poudyal S , Ramachandra Rao M S , Jaiswal Manu 
Published: February 2024

Abstract
Turbostratic multilayer graphene presents a unique system with a large number of twisted interfaces with variable twist angles. In this work, we have systematically studied the laser excitation energy dependence of the Raman modes of turbostratic graphene. The combination of 4 different laser energies is shown to be important to reveal the twist angles ranging from 5∘ to 30∘ present at the same lateral position of the sample. Rotational or R-modes and D-like modes are observed, which directly arise from additional momentum transfer from the potential of corresponding superlattices. Trends in their dispersion and intensity are discussed. The resonant window for laser excitation indicates lowered positions of the van Hove singularities. Furthermore, an anomalous broadening factor of 0.17–0.265 eV is estimated for the resonance window when compared to the literature on isolated twisted bilayer graphene. Interestingly, a weak dependence of the R-modes on the laser wavelength is also observed. Finally, the dispersion of the 2D modes is also presented.
Intelligent fault diagnosis method of rolling bearing based on multi-source domain fast adversarial network

Published: February 2024

Abstract
Fault diagnosis of rolling bearings is among the most crucial links in the prognostic and health management of bearings. To solve the problem of single-source domain transfer learning that cannot adapt well to the target domain, a transfer diagnosis method based on multi-source domain fast adversarial network (MSDFAN) is proposed. First, signals from all domains are input into a common subnetwork of fast neural networks to reduce the complexity and network running time of neural networks. Secondly, several adversarial networks are constructed as domain specific feature extractors and then use Higher-order Moment Matching to reduce distribution differences between A and B domains. The two experimental cases of rolling bearing support the effectiveness and superiority of the proposed MSDFAN.
OPTIma: simplifying calorimetry for proton computed tomography in high proton flux environments

Published: February 2024

Abstract

Objective. Proton computed tomography (pCT) offers a potential route to reducing range uncertainties for proton therapy treatment planning, however the current trend towards high current spot scanning treatment systems leads to high proton fluxes which are challenging for existing systems. Here we demonstrate a novel approach to energy reconstruction, referred to as ‘de-averaging’, which allows individual proton energies to be recovered using only a measurement of their integrated energy without the need for spatial information from the calorimeter. Approach. The method is evaluated in the context of the Optimising Proton Therapy through Imaging (OPTIma) system which uses a simple, relatively inexpensive, scintillator-based calorimeter that reports only the integrated energy deposited by all protons within a cyclotron period, alongside a silicon strip based tracking system capable of reconstructing individual protons in a high flux environment. GEANT4 simulations have been performed to examine the performance of such a system at a modern commercial cyclotron facility using a σ ≈ 10 mm beam for currents in the range 10–50 pA at the nozzle. Main results. Apart from low-density lung tissue, a discrepancy of less than 1% on the Relative Stopping Power is found for all other considered tissues when embedded within a 150 mm spherical Perspex phantom in the 10–30 pA current range, and for some tissues even up to 50 pA. Significance. By removing the need for the calorimeter system to provide spatial information, it is hoped that the de-averaging approach can facilitate clinically relevant, cost effective and less complex calorimeter systems for performing high current pCTs.
Torsional actuation and vari-stiffness characteristics of SMA/basalt hybrid braided composite tubes
Authors: Ke Jun , Zhang Yating , Wu Zhenyu , Qin Shuang , Pan Wencheng 
Published: February 2024

Abstract
Shape memory alloy hybrid composite (SMAHC) tubes have the potential to actively control the torsional stiffness of structures. In this work, shape memory alloy (SMA) wires orthogonally braided with basalt fiber were heated by electricity to generate the torsional torque of the SMAHC tube, and then the torsional stiffness of the tube was measured. The macroscopic finite element model of the SMAHC tube was established to assist in the analysis of the torsional stiffness variation before and after heating. According to the experimental results, the actuating torsional ability was affected by the phase transformation recovery force of SMA. The active control of torsional stiffness depends on the change of SMA modulus, the magnitude and direction of SMA wires’ recovery force, and the thermodynamic properties of matrix at different temperatures. Then an evaluation model for the torsional stiffness control effect was proposed. These research results can be used for the adaptive control of the stiffness and vibration characteristics of rotating composite structures, and provide a novel and effective method for the control of structural torsional characteristics with lightweight effects.
Adaptive optimal fault-tolerant vibration control and sensitivity analysis of semi-active suspension based on a self-powered magneto-rheological damper
Authors: Gao Xiang , Jiang Qingyan , Zhang Guangcheng , Niu Junchuan , Dong Ruichun , He Lei 
Published: February 2024

Abstract
To reuse the energy dissipated by vehicle suspension, a semi-active suspension with a self-powered magneto-rheological damper is proposed. An electromechanical coupling model of self-powered semi-active suspension is established. The energy conversion efficiency is defined and investigated by changing the electrical parameters. By considering unmodeled dynamics and perturbation values, an adaptive optimal fault-tolerant control algorithm is proposed to ensure the vibration-isolation performance. The robust index of the adaptive optimal fault-tolerant control algorithm is constructed using the Lyapunov equation and evaluated by changing the key parameters. The sensitivity of the key parameters to the damping force is investigated using a grey relation analysis approach. Furthermore, multi-objective optimization between the vibration-isolation capability and energy harvesting is conducted. Via analysis, the proposed suspension can harvest more energy near the second resonance range. Compared to passive control and self-powered mode, the adaptive optimal control algorithm mitigates vibration more significantly in the time and frequency domains, respectively, under stochastic excitation. The robust index is most sensitive to inductance and the diameter of the magnetism cylinder. The length of the damping channel and the diameter of the magnetism cylinder influence the sensitivity of key parameters to the damping force most obviously.
Towards the generation of mechanical Kerr-cats: awakening the perturbative quantum Moyal corrections to classical motion
Authors: Cortiñas Rodrigo G 
Published: February 2024

Abstract
The quantum to classical transition is determined by the interplay of a trio of parameters: dissipation, nonlinearity, and macroscopicity. Why is nonlinearity needed to see quantum effects? And, is not an ordinary pendulum quite nonlinear already? In this manuscript, we discuss the parameter regime where the dynamics of a massive oscillator should be quantum mechanical in the presence of dissipation. We review the outstanding challenge of the dynamical generation of highly quantum mechanical cat states of a massive ‘pendulum’, known as Kerr-cats. We argue that state-of-the-art cold atom experiments may be in a position to reach such a nonlinear regime, which today singles out superconducting quantum circuits. A way to stabilize Schrödinger cat superpositions of a mechanical atomic oscillator via parametric squeezing and further protected by an unusual form of quantum interference is discussed. The encoding of a neutral atom Kerr-cat qubit is proposed.
