Abstract
Purpose To assess and describe the outcomes of corneal allograft intrastromal ring segment (CAIRS) implantation in eyes with keratoconus.
Methods In this retrospective analysis, we examined the early postoperative results of CAIRS (KeraNatural) implantation after cutting a corneal tunnel with a femtosecond laser device (Ziemer Z6) in patients with keratoconus. Outcome measures included best-corrected distance visual acuity (BCDVA), spherical equivalent (SE), maximal keratometry (Kmax), refractive astigmatism (RA), higher-order aberrations (HOAs), and root mean square total aberrations (total RMS), evaluated both before and a variable time after surgery, ranging from at least 30 days to 338 days, with a mean follow-up time of 141.1 ± 79.9 days postoperatively.
Results A total of 17 eyes with keratoconus of 16 patients (mean age of 36.2 ± 17.3 years) were treated. In one eye, previous corneal UVA cross-linking (CXL) was reported in the medical history, and 9 eyes underwent adjunctive CXL at least 1 month postoperatively due to previously documented progressive disease. BCDVA (mean ± SD) improved from preoperative values of 0.43 ± 0.16 logMAR to 0.19 ± 0.14 logMAR postoperatively (p < 0.001). Furthermore, the results show a significant decrease in spherical and astigmatic refraction, with the mean SE decreasing from − 2.9 ± 4.7 D to − 0.7 ± 3.6 D (p = 0.004). Mean RA slightly changed from − 3.42 ± 2.18 D to − 2.51 ± 2.31 D (p = 0.13). Additionally, mean Kmax significantly decreased from 57.3 ± 5.5 D to 51.4 ± 5.7 D (p < 0.001). In the comparison of pre- to postoperative HOA and total RMS values at 4, 5, and 6 mm, a slight tendency for improvement was found; however, these changes were not statistically
significant (p > 0.05, each).
Conclusion CAIRS implantation reduced corneal ectasia and improved BCDVA in patients with keratoconus. This highlights its potential as an effective visual rehabilitation strategy, particularly for patients who are intolerant to wearing contact lenses.
Nondegenerate and degenerate multi-solitons for the reverse-time nonlocal nonlinear Schrödinger model
Authors: Liu Jin-Hao , Geng Kai-Li , Dai Chao-Qing 
Published: February 2025

Abstract
We employ the Hirota bilinear method to systematically derive nondegenerate bright one- and two-soliton solutions, along with degenerate bright-dark two- and four-soliton solutions for the reverse-time nonlocal nonlinear Schrödinger equation. Beyond the fundamental nondegenerate one-soliton solution, we have identified and characterized nondegenerate breather bound state solitons, with particular emphasis on their evolution dynamics. Furthermore, we have conducted a comprehensive analysis of the dynamic behavior exhibited by degenerate bright-dark soliton structures.These findings offer potential applications for nondegenerate and degenerate soliton interactions in nonlocal models.
Smart DIC-3D: towards full-automatic, user-independent, accurate and precise 3D shape and displacement measurement
Authors: Pan Bing , Zhao Jianhui , Jia Liang , Yu Liping 
Published: February 2025

Abstract
Existing three-dimensional digital image correlation (3D-DIC) for surface 3D shape and deformation measurement requires the users to input key calculation parameters (e.g. subset size) to proceed with stereo and temporal matching. However, the lack of clear guidelines for optimal parameter selection often leads to ambiguity and uncertainty in the final measurements. To eliminate the ambiguity and realize full-automatic, user-independent, accurate and precise 3D-DIC measurements, we present a simple yet effective Smart DIC-3D. By fully considering local speckle quality and deformation, Smart DIC-3D automatically selects the optimal subset size for each calculation point in both stereo and temporal matching. Additionally, a fully automated initial value estimation method, combining speeded-up robust features with a reliability-guided displacement tracking strategy, ensures automatic reliable initial value estimation for both matching processes. Both numerical experiments with simulated stereo speckle images and practical applications including complex shape reconstruction and non-uniform deformation measurement were conducted to verify the effectiveness and accuracy of Smart DIC-3D. The experimental results show that Smart DIC-3D has lower random and under-matched systematic errors than regular 3D-DIC, enabling high-fidelity 3D shape reconstruction and deformation measurement independent of the practitioners’ input.
Thickness dependence of chemical ordering and fourfold exchange anisotropy in FeRh/CoFe bilayers

Published: February 2025

Abstract
Fourfold exchange anisotropy has recently been discovered in bilayers consisting of a ferromagnetic (FM) layer exchange-coupling with an epitaxial antiferromagnetic (AF) layer. The chemical ordering of the AF layer plays an important role in the interfacial exchange coupling of AF/FM bilayers. Herein, we studied the thickness dependence of the chemical ordering and fourfold exchange anisotropy of FeRh/CoFe bilayers before and after the AF-FM phase transition of FeRh. The chemical ordering parameter of FeRh obtained by X-ray diffraction increases with thickness due to the decrease in the proportion of low-order interfaces, which results in an increase in the magnetic phase transition temperature and a decrease in the phase transition width, residual magnetization in the AF state, and lattice constant. After the occurrence of the AF-FM phase transition, the fourfold exchange anisotropy observed in the CoFe layer by magneto-optical Kerr effect changes from the FeRh〈110〉 to 〈100〉 directions, indicating the orientation change in the cubic magnetocrystalline anisotropy of FeRh. The fourfold exchange anisotropy measured by ferromagnetic resonance continues to increase with the FeRh thickness, indicating an effective thickness by far larger than that of chemically disordered AF systems. The FeRh/FM exchange coupling is highly dependent on chemical ordering, not only on the low-order surface of a few nanometers but also on the high-order interior extending to a depth of tens of nanometers.
Tracking Long-Distance Power Transmission Line under Uncertain Wind Fields by QUAV Using Nonlinear Model Predictive Control
Authors: Li Kun , Kang Liping , Han Ying , Leau Yu-Beng 
Published: February 2025

Abstract
In long-distance power transmission line inspections, utilizing a quadrotor unmanned aerial vehicle (QUAV) to stably and safely track high-voltage power lines from a safe distance has been demonstrated as an effective method. However, due to the intricate 3D spatial configuration of the power lines and the challenges in accurately detecting them, maintaining a consistent and safe tracking distance between the drone and the power lines remains a significant challenge. Additionally, the variability of wind patterns in long-distance inspection areas further complicates the task of ensuring stable tracking. Therefore, considering both the kinematic constraints of the QUAV-gimbal camera system and the influence of dynamic wind fields, this study proposes a Nonlinear Model Predictive Controller (NMPC) based approach for QUAV power line tracking. Initially, the QUAV's target tracking control task is formulated as an optimization problem, incorporating stringent motion attitude constraints to establish a cost function for target tracking distance in 3D space. Subsequently, by integrating gimbal camera functionality, a field-of-view (FOV) cost model is developed to determine the QUAV's target point while accounting for wind disturbance factors. Through the implementation of the NMPC controller, continuous airborne tracking is achieved while mitigating adverse effects from time-varying wind fields. Ultimately, optimal control input commands are generated for use with both the QUAV and gimbal controllers. Simulation experiments validate that this method effectively enables the QUAV to track long-distance power lines within time-varying wind field environments, with high precision, efficiency, and robust tracking performance.
First principles prediction of the valley Hall effect in ScBrCl monolayer
Authors: Yu Xiang , Li Ping , Zhang Chang-Wen 
Published: February 2025

Abstract
Two-dimensional ferrovalley materials with valley-dependent Hall effect have attracted great interest due to their significant applications in spintronics. In this paper, by using first-principles computational simulations, we predict that the ScBrCl monolayer is a two-dimensional (2D) ferrovalley material with valley-dependent multiple Hall effects. After calculations, we found that the ScBrCl monolayer has excellent thermodynamic stability and kinetic stability, and has a high magnetic transition temperature. When the magnetization direction is turned from in-plane to out-of-plane, a large valley polarization of 44 meV can be generated. In particular, under 5.1%-5.3% tensile strain conditions, ScBrCl monolayer can achieve quantum anomalous Hall effect, and further prove its existence through non-zero Chern number and non-trivial edge state. Our discovery enriches the research on valley-dependent Hall effect and promotes the potential application of 2D Janus monolayer in valley electronics.

Abstract
Determining the electronic structure of La3Ni2O7 is an essential step towards uncovering their superconducting mechanism. It is widely believed that the bilayer apical oxygens play an important role in the bilayer La3Ni2O7 electronic structure. Applying the hybrid exchange-correlation functionals, we obtain a more accurate electronic structure of La3Ni2O7 at its high-pressure phase, where the bonding d

band is below the Fermi level owing to apical oxygen. The symmetry properties of this electronic structure and its corresponding tightbinding model are further analyzed. We find the antisymmetric part is highly entangled leading to a minimal nearly degenerate two-orbital model. Then, the apical oxygen vacancies effect is studied using the dynamical cluster approximation. This disorder effect strongly destroys the antisymmetric β Fermi surface leading to the possible disappearance of superconductivity.

Abstract
The Nuclotron-based Ion Collider fAcility (NICA) is currently under construction at JINR, with the first beam tests of the Collider scheduled for the second half of 2025. The NICA project aims to provide colliding beams for studying heavy fully stripped ion collisions at energies of up to 4.5 GeV/u. The NICA accelerator complex comprises several components: the operational heavy ion linac HILAC with an energy of 3.2 MeV/u, the superconducting Booster synchrotron with a maximum energy of 600 MeV/u, the superconducting Nuclotron synchrotron capable of accelerating gold ions to 3.9 GeV/u, and two storage rings with two interaction points currently being installed. Two electron cooling systems are included—one in the Booster synchrotron with a maximum electron energy of 60 keV, and another in the Collider with two electron beams, each with a maximum energy of 2.5 MeV. Additionally, two stochastic cooling systems are implemented. The status of the NICA accelerator complex, including its cooling systems, is presented. Experimental results from electron cooling studies conducted during the commissioning of the injection complex are reported. Plans for further development and application of electron and stochastic cooling systems are also described.
Myth Versus Reality: A Review of Social Media Claims and Scientific Evidence for Arnica Montana in Postinjectable Procedures
Authors: Ryzhaya Natalia , Rivers Jason K. 
Published: February 2025

BACKGROUND
Reduced bruising and swelling after aesthetic procedures accelerates recovery. Arnica montana is widely used by physicians and promoted on social media, although its efficacy in aesthetic medicine remains uncertain.

OBJECTIVE
To evaluate the validity of social media claims regarding Arnica's therapeutic benefits, focusing on aesthetic injectable procedures.

MATERIALS AND METHODS
Social media platforms, TikTok and Reddit, were searched on April 24, 2024, covering a 2-year period, using terms: “arnica montana,” “arnica,” “arnica filler,” “arnica botox,” and “arnica gel.” A literature review was conducted using OVID Medline and Embase databases with keywords “arnica” and “arnica montana.”

RESULTS
A total of 48 TikTok posts and 305 Reddit entries were identified; with 91.7% and 58% of posts, respectively, endorsing Arnica use, primarily without scientific evidence. The literature review revealed limited and mixed evidence for Arnica's efficacy, with only 1 study addressing dermatologic injectable procedures. Systematic reviews indicated a small effect size for Arnica in surgical settings, with no specific focus on dermatologic applications.

CONCLUSION
Despite its popularity on social media and frequent use by health care providers, scientific evidence supporting Arnica's efficacy in reducing bruising and swelling after aesthetic procedures remains inconclusive. Social media discussions predominantly supported Arnica use, with limited opposition noted.

Authors: Minsinger Kristopher D. , Graber Judith M. , Nezam Hasan , Caruth Julie , Udasin Iris 
Published: February 2025

Abstract

Objective
In the past decade, U.S. transport accidents have resulted in over 370,000 fatalities. Research on medical history non-disclosure during mandatory regulatory exams has been limited. This study used the National Transportation Safety Board’s (NTSB) Case Analysis and Reporting Online (CAROL) database to: (1) Identify non-disclosure, (2) Assess non-disclosure patterns, (3) Evaluate CAROL’s research potential.

Methods
The CAROL database was searched for U.S. cases (01/01/2010-01/29/2024) involving fatalities and medically-related causes. Non-disclosure was defined as operators with undisclosed preexisting conditions or medications in NTSB reports. Twelve cases with recurring themes were described in detail.

Results
Of 3,012 accidents, 258 met our criteria; 80 (31%) indicated examinee non-disclosure in the NTSB investigation.

Conclusion
Operator non-disclosure in NTSB cases underscores CAROL’s value for further investigations and highlights the risks non-disclosure poses to U.S. transportation safety.

Published: February 2025

ABSTRACT

Objective: This study examines the psychometric properties of a workplace-adapted version of an existing Technostress scale to assess technostress in workers over 50 across different companies.

Methods: Data were collected from 470 workers over 50 across finance, packaging, and steel sectors. We evaluated the internal consistency, criterion validity, and factor structure of the Technostress scale using Cronbach’s alpha, McDonald’s Omega, Confirmatory Factor Analysis, and correlations with stress, coping, well-being, and workability.

Results: Scale and subscales demonstrated strong reliability (coefficients>0.75) and validity. CFA confirmed bifactor model with optimal fit indices (CFI = 0.98, TLI = 0.96, RMSEA = 0.05). Technostress correlated positively with stress and negatively with well-being and workability. Significant differences in technostress were observed by sex and occupational role.

Conclusions: The adapted scale is a reliable tool for evaluating technostress among older workers, supporting tailored interventions to enhance workplace well-being and productivity.

Published: February 2025

Objective
The objective of this study is to investigate the risk and prognostic factors for radioactive iodine (RAI)-refractory (RAIR) differentiated thyroid cancer (DTC) with distant metastasis.

Methods
A total of 128 patients with distant metastasis-DTC who underwent iodine-131 radiotherapy were included in this cohort study. After exclusion, 75 DTC patients who were resistant to radioiodine therapy and 53 patients in whom the treatment was successful were finally included. Clinical data as well as BRAF V600E and telomerase reverse transcriptase (TERT) promoter mutations were compared between these two groups to predict the risk of RAIR. Patients with RAIR-distant metastasis-DTC were followed up to further investigate the risk factors for disease progression after the cancer became iodine-refractory.

Results
Univariate analysis showed that TERTp mutation, age at diagnosis, mean maximum tumor diameter, lymph node metastasis, synchronous metastasis or heterochronous metastasis, mean cumulative dose of RAI, and preoperative Tg were statistically different between the RAIR and RAIE (radioiodine efficient) groups. Logistic regression analysis further found that the TERTp mutation may be risk factor for iodine refractory occurrence. During the follow-up of RAIR-distant metastasis-DTC patients, 41 patients developed disease progression, and 24 patients had good disease control.

Conclusion
We found that TERTp mutation is correlated with the poor curative effect of RAI therapy in distant metastasis-DTC. Once iodine refractory occurs, patients aged 55 years or older are more likely to develop disease progression.

Authors: Lazorwitz Aaron , Aquilante Christina L. , Shortt Jonathan A. , Gignoux Christopher R. , Teal Stephanie , Sheeder Jeanelle 
Published: February 2025

OBJECTIVE:
To identify novel genetic loci associated with differences in serum etonogestrel concentrations among contraceptive implant users.

METHODS:
We conducted a cross-sectional analysis in which we enrolled healthy, reproductive-aged (age 18–45 years) participants who had been using etonogestrel implants for 12–48 months. Participants underwent a single-time blood draw for measurement of serum etonogestrel concentrations by liquid chromatography–tandem mass spectrometry and the extraction of DNA from whole blood. We genotyped participants using the Illumina Infinium Global Diversity Array with Enhanced PGx and imputed genotyping results using the TOPMed imputation server. We performed genome-wide complex trait analysis using a linear mixed model leave-one-chromosome-out association analysis to identify genetic variants associated with serum etonogestrel concentrations.

RESULTS:
We enrolled 900 etonogestrel implant users, with a median age of 22.3 years (range 18.0–41.5 years), median body mass index (BMI) 26.0 (range 18.5–52.0), and median duration of implant use 27 months (range 12–48 months). Most participants self-reported their race as White (49.3%) and ethnicity as Hispanic or Latina (52.9%). Participants had a median serum etonogestrel concentration of 126.9 pg/mL (range 39.4–695.1 pg/mL). Including BMI, duration of implant use, and three principal components as covariates in the genome-wide complex trait analysis, we identified no genetic variants with minor allele frequencies at or above 5% that were associated with serum etonogestrel concentrations at genome-wide significance (P<5.0×10−8). When including rare genetic variants (minor allele frequencies at or above 1%), we discovered 10 genetic loci of interest (RNF114; LINC02405; SYNE1; TSPAN14; CRYZL2P-SEC16B; CHRNA9; RIMS1; CCDC88C; and CBL), all containing genetic variants associated with increased serum etonogestrel concentrations. Among these novel genetic loci associated with serum etonogestrel concentrations, only one (CRYZL2P-SEC16B) has potential, albeit limited, physiologic plausibility.

CONCLUSION:
Despite enhanced coverage for known pharmacogenomic variants, we found no significant associations between interindividual variability in contraceptive implant pharmacokinetics and genetic loci directly involved in exogenous steroid hormone metabolism.

Biology of the avian respiratory system: development, evolutionary morphology, function and clinical considerations
Authors: Maina John N. , Schachner Emma R. 
Published: February 2025

The respiratory biology of birds has been of interest to researchers for centuries, particularly owing to its dramatically heterogeneous structure, unusual ability for non-ventilatory structures to invade nearly all parts of the body (including the skeleton) in many taxa, and its exceptional efficiency under high-altitude hypoxia. Advances in imaging, experimental and developmental techniques, as well as recent palaeontological specimens have facilitated new discoveries, analyses and progress in the field. Comprehensively, this theme issue shows the origin of the modern avian respiratory system, current controversies and how the evolution of respiratory structures in birds has impacted their biology from the molecular, to the cellular, to the phylogenetic level. This collection of articles addresses progress the field has made, gaps in our knowledge and where the field needs to go, with a primary focus on adult and embryonic form and function but also touching on vocalization and clinical aspects of avian respiratory biology.
This article is part of the theme issue ‘The biology of the avian respiratory system’.
