The Evolving Landscape of Small Fiber Neuropathy
Authors: Devigili Grazia , Lombardi Raffaella , Lauria Giuseppe , Cazzato Daniele 
Published: October 2024

AbstractSmall fiber neuropathy (SFN) belongs to a heterogeneous group of disorders in which thinly myelinated Aδ and unmyelinated C-fibers are primarily affected, leading to neuropathic pain and autonomic symptoms. SFN can be associated with systemic conditions such as diabetes, autoimmune diseases, exposure to drugs and toxins, and infection, with the list of associated diseases continuing to expand. Variants in the SCN9A, SCN10A, and SCN11A genes encoding Nav 1.7, Nav 1.8, and Nav 1.9 sodium channel subunits, as well as in the TRPA1 gene, have been found in SFN patients, expanding the spectrum of underlying conditions and enhancing our understanding of pathophysiological mechanisms. There is also growing interest in immune-mediated forms that could help identify potentially treatable subgroups. According to international criteria, diagnosis is established through clinical examination, the assessment of intraepidermal nerve fiber density, and/or quantitative sensory testing. Autonomic functional tests allow for a better characterization of dysautonomia in SFN, which can be subclinical. Other tests can support the diagnosis. Currently, the management of SFN prioritizes treating the underlying condition, if identified, within a multidisciplinary approach that combines symptomatic pain therapy, lifestyle changes, and biopsychological interventions. Emerging insights from the molecular characterization of SFN channelopathies hold promise for improving diagnosis, potentially leading to the discovery of new drugs and refining trial designs in the future. This article reviews the clinical presentation, diagnostic workup, and advancing knowledge of associated conditions and interventional management of SFN.

Published: October 2024

AbstractHepatocellular carcinoma (HCC) remains a significant global health challenge, particularly for patients awaiting liver transplants (LTs) due to the scarcity of donor organs. During the waiting period, a multidisciplinary approach becomes crucial to optimize tumor treatment and preserve liver function. In recent years, interventional radiology has emerged as an integral part of treatment strategies. It has played a pivotal role in bridging and downstaging patients on the path to transplantation. Interventional radiologists administer minimally invasive locoregional therapies to HCC patients on LT waiting lists. Additionally, they address complications such as portal hypertension and portal vein thrombosis, which can lead to clinical deterioration and jeopardize transplant candidacy. This article examines the pivotal role of interventional radiology in the management of HCC, highlighting recent studies and advancements within the field. Additionally, it provides a concise review of the eligibility criteria for LT in patients with HCC, alongside a discussion of the surgical techniques employed in LT for these patients.
Frequency linearization of voltage controlled oscillator (VCO) for 2 µs frequency modulated continuous wave (FMCW) reflectometer
Authors: Seo Seong-Heon 
Published: October 2024

Frequency modulated continuous wave reflectometers have been widely used to measure plasma density profiles in many magnetic fusion devices. The frequency modulation (FM) time of the KSTAR reflectometer was 20 µs, that is, the FM rate was 50 kHz. However, the edge density of the KSTAR tokamak fluctuates typically over the frequency range of 20–50 kHz in the ELMy H-mode plasmas. Therefore, the density profile changes significantly during the FM time, causing significant distortion in the density profile measurements. The FM rate must be increased at least ten times faster than the density fluctuation frequency. A new voltage controlled oscillator (VCO) driver is designed based on the AD8067 operational amplifier to achieve a FM time of 2 µs. The VCO output frequency is linearly modulated by predistorting the tuning voltage of VCO using a 400 MSamples/s arbitrary waveform generator. The resulting output frequency of the VCO is measured by mixing the VCO output with a fixed frequency synthesizer signal and measuring the mixer intermediate frequency using a 2.5 GSamples/s digitizer. The tuning voltage is adjusted to minimize the amount by which the measured frequency deviates from the linearly modulated frequency. A simple linear adjustment proportional to the deviation does not effectively suppress the nonlinearity in FM. The response time of the VCO driver and the VCO input interface should be taken into account by solving the entire circuit equation. In this paper, the developed VCO driver circuit and the frequency linearization method are described.
Boltzmann optical thermometry for cryogenics
Authors: Zeman Marek , Camus Philippe , Chanelière Thierry 
Published: October 2024

We propose and implement an optical technique to access the local temperature of an erbium doped crystal by probing the electron spin population under magnetic field. We reliably extract the sample temperature in the range 2–7 K. We additionally discuss the suitability of our method as a primary standard for cryogenic thermometry. By adding an auxiliary heating laser, we are able to measure the interface conductance between the dielectric crystal and the cold plate of the cryostat by exploring different cooling configurations.

Published: October 2024

Our study demonstrates second harmonic generation (SHG) in a high confinement LiNbO3 rib waveguide through type-I birefringence phase matching of fundamental modes. The combination of micro-waveguide dispersion and material birefringence reveals unique SHG characteristics that complement the performance of standard LiNbO3 on insulator (LNOI) components. Dual-pump wavelength phase matching in the near-infrared and mid-infrared regions is shown in a given waveguide. These two wavelengths can be positioned in the 1.1–3.5 μm range or converge near 1.5 μm by adjusting the core waveguide size or through temperature tuning. A 25 °C temperature change enables a broad pump tunability band of 300 nm, ranging from 1350 to 1650 nm, with a conversion efficiency exceeding 40 %/W/cm2 within a single waveguide. A temperature tuning range of up to 900 nm is foreseen by tailoring the waveguide core size. In addition, a broadband response of 150 nm within the telecom window is demonstrated experimentally. The nonlinear waveguide, etched in a thin film membrane, is combined with titanium-indiffused waveguides to form a monolithic LiNbO3 component. This configuration provides low coupling losses of 0.8 dB and single-mode operation. It paves the way for a new generation of versatile and cost-effective frequency conversion components with wide-band spectral responses suitable for optical communications, environmental sensing, and quantum information processing.
Exploring electronic resonances in pyridine: Insights from orbital stabilization techniques
Authors: Pyla Maneesh , Matsika Spiridoula 
Published: October 2024

Electron attachment to pyridine results in electronic resonances, metastable states that can decay through electronic or nuclear degrees of freedom. This study uses orbital stabilization techniques combined with bound electronic structure methods, based on equation of motion coupled cluster or multi-reference methods, to calculate positions and widths of electronic resonances in pyridine that exist below 10 eV. We report four 2B1 and four 2A2 resonances, including one 2B1 not previously reported experimentally and two 2A2 resonances not reported at all in the literature. The two lower energy resonances are one-particle shape resonances, while the remaining are mixed or primarily core-excited resonances. Multi-reference perturbation theory provides the best description of these resonances, especially when their character is mixed. We describe the character of these resonances qualitatively and calculate Dyson orbitals, which provide information about their decay channels.
Quantized embedding approaches for collective strong coupling—Connecting ab initio and macroscopic QED to simple models in polaritonics
Authors: Lindel Frieder , Lentrodt Dominik , Buhmann Stefan Yoshi , Schäfer Christian 
Published: October 2024

Collective light–matter interactions have been used to control chemistry and energy transfer, yet accessible approaches that combine ab initio methodology with large many-body quantum optical systems are missing due to the fast increase in computational cost for explicit simulations. We introduce an accessible ab initio quantum embedding concept for many-body quantum optical systems that allows us to treat the collective coupling of molecular many-body systems effectively in the spirit of macroscopic quantum electrodynamics while keeping the rigor of ab initio quantum chemistry for the molecular structure. Our approach fully includes the quantum fluctuations of the polaritonic field and yet remains much simpler and more intuitive than complex embedding approaches such as dynamical mean-field theory. We illustrate the underlying assumptions by comparison to the Tavis–Cummings model. The intuitive application of the quantized embedding approach and its transparent limitations offer a practical framework for the field of ab initio polaritonic chemistry to describe collective effects in realistic molecular ensembles.
The more proficient the learners, the less sophisticated their L2 vocabulary?
Authors: Bottini Raffaella , Le Foll Elen 
Published: October 2024

Abstract
Mean-frequency scores of lexical sophistication are used to evaluate written and spoken language production. They
are calculated using word frequencies extracted from a reference corpus. Using mixed-effects regression models, we analyse the
strength of the relationship between L2 proficiency and mean-frequency scores in spoken and written texts using reference corpora
representing different modes and registers. We control for task and topic effects. We observe that mean-frequency measures of
lexical sophistication are considerably more influenced by the mode and register of the reference corpus used to calculate these
scores than by language users’ proficiency level. Advanced language users produce more frequent vocabulary, typical of the target
register, in both spoken monologues and written essays. These results provide evidence in favour of a conceptual and
terminological shift from lexical sophistication to register appropriateness (as suggested by
Durrant & Brenchley, 2019) to refer to the construct captured by mean-frequency
scores of vocabulary use.
“The twain is crossing”
Authors: Adam Naomi , Ghintuială Paula 
Published: October 2024

Abstract
The storyworld presented in the 2023 fantasy-comedy film Barbie is predicated upon a simple
ontological binary: there is the Real World, in which humans reside, and Barbie Land, populated by plastic dolls, and it is
roundly accepted that “never the twain shall cross”. However, throughout the film this divide is problematised, as the two domains
impinge upon one another so consistently that Barbie herself recognises that “[t]he twain is crossing”. In this article, we explore the complex ontological structure underlying the Barbie film. A
multimodal stylistic approach is adopted, and combined with insights from possible worlds theory, in order to investigate the
linguistic, structural and visual features which present permeable and liminal spaces and occasion incidences of ontolepsis.
Ultimately, the analysis serves to illuminate Barbie’s playful approach to multiple, interwoven, and overlapping
ontological levels — be they in Barbie Land, the Real World, or even our own real world.
Applying Cognitive Linguistics to elucidate the meanings of the particles IN/OUT and UP/DOWN in L2
classrooms
Authors: Piquer-Píriz Ana M. , Martín-Gilete Marta 
Published: October 2024

Abstract
Cognitive Linguistics offers valuable insights for second language instruction, particularly in enhancing
motivated polysemy to facilitate vocabulary acquisition. This paper reports on a longitudinal, classroom-based study and analyses
the design, implementation, and assessment of activities inspired by Cognitive Linguistics, elucidating the polysemous meanings of
the particles IN/OUT and UP/DOWN. The study involved an experimental group comprising 81 Spanish secondary school students and a
control group of 26 students. Following a pre-test/post-test design, participants completed two tests (a gap-fill particle test
and a lexical depth test) designed to measure students’ command of polysemous meanings. Despite positive teacher feedback and a
perceived increase in awareness of polysemy, the experimental learners showed no statistically significant improvement in the test
results. We conclude that a comprehensive approach is required to evaluate learning outcomes, encompassing pedagogical experience,
classroom-based research factors, and effective assessment measures.

The pseudospectrum and transient of Kaluza–Klein black holes in Einstein–Gauss–Bonnet gravity
Authors: Chen Jia-Ning , Wu Liang-Bi , Guo Zong-Kuan 
Published: October 2024

Abstract
The spectrum and dynamical instability, as well as the transient effect of the tensor perturbation for the so-called Maeda–Dadhich black hole, a type of Kaluza–Klein black hole, in Einstein–Gauss–Bonnet gravity have been investigated in framework of pseudospectrum. We cast the problem of solving quasinormal modes (QNMs) in AdS-like spacetime as the linear evolution problem of the non-normal operator in null slicing by using ingoing Eddington–Finkelstein coordinates. In terms of spectrum instability, based on the generalized eigenvalue problem, the QNM spectrum and ε-pseudospectrum has been studied, while the open structure of ε-pseudospectrum caused by the non-normality of operator indicates the spectrum instability. In terms of dynamical instability, we introduce the concept of the distance to dynamical instability, which plays a crucial role in bridging the spectrum instability and the dynamical instability. We calculate such distance, named the complex stability radius, as parameters vary. Finally, we show the behavior of the energy norm of the evolution operator, which can be roughly reflected by the three kinds of abscissas in context of pseudospectrum, and find the transient growth of the energy norm of the evolution operator.
Solution-processed lead halide perovskite films for application in perovskite solar cells: from coating methods to growth dynamics
Authors: Xiao Yuhuan , Zhou Conghua 
Published: October 2024

Abstract
After 15 years of development, perovskite solar cells have achieved a certified efficiency of >26%, offering one of the most reliable solutions for green energy. This progress should be ascribed to the excellent optoelectronic properties of metal halide perovskite film, for example, the excellent extinction behavior and the long diffusion length of charge carriers. Basically, these properties rely on the crystallization quality. In recent years, many methods have been developed to grow uniform and well-crystallized perovskite films, such as one-step and two-step solution-based methods, and evaporation methods. These methods help to grow films with areas ranging from several to hundreds of square centimeters. For each method, regulating the growth dynamics of perovskites has remained as one of the main tasks. Here, in this review, we discuss the coarsening dynamics of lead halide perovskites when using the solution-based methods, such as one-step or two-step spincoating, and bladecoating. Strategies such as component engineering, solvent engineering and additive engineering are briefly introduced and discussed. Finally, some perspectives are given.

Published: October 2024

Abstract
Based on the first-principles calculation, the electronic and optical properties of the graphene/MoS2 heterostructure at different twisting angles are studied. The interface contact type changes from N-Schottky contact to Ohmic contact with the interlayer twisting angle of 40.90°, which is accompanied by the interfacial charge transfer from graphene to MoS2, and the increase of the contribution of Mo–d

2 orbitals in the valence band. Interestingly, the absorption coefficient, reflectivity and refractive index are improved in the infrared region when the twisting angle is 40.90°. In the visible light range, the absorption coefficient increases, while the refractive index decreases, and the reflectivity at 2.8 eV increases. In the ultraviolet region, the absorption coefficient reaches 1.2 × 106 cm−1 at 11.6 eV with a twisting angle of 30°. The results provide an effective way to apply materials in the photoelectric field.
Influence of local Dzyaloshinskii–Moriya interaction on spin waves in symmetrical heavy metal/ferromagnet/heavy metal multilayer
Authors: Yang Zhi , Liu Changjiang , Yang Xiaofei , Zhang Yue 
Published: October 2024

Abstract
In a heavy metal/ferromagnet/heavy metal multilayer with inversion symmetry, the total interlayer Dzyaloshinskii–Moriya interaction (iDMI) is expected to be absent while the local iDMI constants for the top and bottom FM atomic layers can still be nonzero. This study investigates the influence of local iDMI on spin waves in this structure, in which the FM medium consists of two atomic layers with opposite local iDMI at the bottom HM/FM interface and the top FM/HM interface. Theoretical analysis and simulations are conducted to examine the spin-wave dynamics and propagation in the symmetrical sandwich structure. The results show that the local iDMI decreases the characteristic frequency of spin waves, indicating a regulation of spin wave propagation by iDMI and shows the asymmetry of spin-wave propagation between the two FM atomic layers due to iDMI. This work paves the way for deep exploration of spin waves in such structures and offers valuable insights for subtle magnetic interactions in other symmetrical multilayers.
Naturalization and Evaluation of Synthetic Random Stripes Pattern for Digital Image Correlation
Authors: Ye Meitu , Guo Min , Xie Meilin , Tian Guangyuan , Shi Heng , Tian Yan 
Published: October 2024

Abstract
The morphology of speckle patterns commonly used in the digital image correlation (DIC) community can be categorized into artificially generated free shapes and computer-synthesized circular dots. Due to the non-repeatability of manually sprayed patterns, researchers tend to favor code-controlled dot patterns, which exist in two forms: ‘white dots on a black background’ and ‘black dots on a white background’. However, from the perspective of biological evolution, these two dot patterns can be hybridized ‘in silico’ using the Turing model to create an intermediate form—the ‘striped-like’ pattern. This hybridization significantly improves species identification and environmental adaptability. Although there have been reports on producing stripe patterns based on the kernel-based Turing model, there is no specific speckle pattern generation specification or comprehensive evaluation research for DIC applications. This paper naturalizes a novel striped speckle pattern and a corresponding generation approach. The pattern quality was assessed and compared with circular dots and hand-sprayed speckles. The stripes pattern outperformed the other two forms regarding Mean Intensity Gradient, q-factor, systematic bias, and random error. Sub-pixel displacement simulation and actual translation test results demonstrate that the proposed striped pattern offers higher precision and robustness in displacement and static strain measurements. Therefore, this striped pattern provides a preferred alternative for DIC technicians.
