Authors: Japelj Nuša , Horvat Nejc 
Published: May 2023

Abstract
Background: The European Health Literacy Questionnaire (HLS-EU-Q47) is a self-assessment tool for standardised measurement of health literacy.
Aim: To translate HLS-EU-Q47 into the Slovenian language and to investigate its reliability and validity in Slovenia.
Method: HLS-EU-Q47 was translated into Slovenian, back-translated, and subjected to a pilot test. The accepted Slovenian version of the questionnaire was mailed to 2,500 randomly selected adult residents of the Republic of Slovenia. Reliability was examined using Cronbach’s alpha for the 1-, 3-, 4-, and 12-factor models addressing health literacy, three main health contexts, four health information processing competencies, and 12 combinations, respectively. Validity was explored with confirmatory factor analysis, univariate analysis, and multiple linear regression.
Results: A total of 517 responses were collected (21% response rate). The highest Cronbach’s alpha was obtained for the 1-factor model (0.950), followed by the 3-, 4-, and 12-factor models. In the confirmatory factor analysis, the 12-factor model provided the most valid results (CFI 0.812; RMSEA 0.067, CI 0.065 to 0.070), followed by the 3-, 4-, and 1-factor models. In the multiple regression model, only the association between self-assessment of health and the health literacy index was statistically significant (p < 0.001).
Conclusion: The Slovenian version of HLS-EU-Q47 is a reliable instrument for measuring health literacy. All models of the questionnaire showed reasonable model fit, but none fully satisfied all validity criteria. Respondents differentiated better between the three main health contexts (health care, disease prevention, and health promotion) than the four health information processing competencies (access, understand, appraise, and apply).
Dimensional Synthesis, Dexterity Analysis and Experimental Validation of a Six Degree of Freedom Parallel Manipulator

Abstract
This paper presents a design approach based on the dimensionless Jacobian matrix to determine the maximum dextrous workspace for a Six Degree of Freedom (DoF) 3-PPSS (P-Prismatic, S-Spherical) parallel manipulator. As the end-effector of the 3-PPSS manipulator can exhibit both translational and rotational motions, the Jacobian matrix mapping the end-effector velocities and the joint velocities will be dimensionally inhomogeneous. These dimensional inconsistencies within its elements make calculating the associated condition number impossible. Hence, a unit vector approach is introduced in this paper to derive a Jacobian matrix with dimensionless terms to study the dexterity characteristics of the 3-PPSS manipulator. The design procedure follows a systematic approach of choosing the manipulator dimensions corresponding to the maximum dextrous workspace. The manipulator dexterity is characterized by the Global Conditioning Index (GCI). This paper also illustrates the Local Conditioning Index (LCI) distribution within the workspace corresponding to the optimal manipulator dimensions. Finally, the performance of the 3-PPSS manipulator is evaluated experimentally by implementing an intelligent control based on the Inter-Integrated Circuit (I2C) protocol.
Ultrasonic Image Artifacts Removing Technique Based on SoS Kernel
Authors: song shoupeng , Chen Dan 
Published: May 2023

Abstract
The ultrasonic image provides direct visualization information of the test sample. However, traditional ultrasonic images often accompany artifacts inevitably, which heavily influence the accurate quantization and evaluation of defects. So far, it has been hard to find a way for eliminating artifacts caused by the diffusion of isacoustic contour, signal tail, or noise simultaneously. To remove different kinds of ultrasonic image artifacts, a novel ultrasonic imaging method is presented using a SoS (Sum of Sinc) kernel. If the envelope of ultrasonic echo is obtained, let it pass through a SoS kernel, then sample the signal at equal intervals determined by the echo signal information degree, and apply the Fourier transform to the discrete sampling data to obtain the Fourier coefficient sequence. After that, use the spectral estimation algorithm to estimate the parameters of the ultrasonic echo signal and reconstruct the echo signal using the estimated parameters. Finally, the ultrasonic image can be obtained by calculating the acoustic field using the reconstructed echoes. Experiments have been performed on a sample with standard defects of straight slot and through-hole, and the experimental results revealed that the imaging method not only improves the quantization accuracy of the defect but also greatly restrains the different types of artifacts.
Numerical Relationship Between Non-visual Metrics and Brightness Metrics - Implications for the Evaluation of Integrative Lighting Systems

Published: May 2023

Abstract
From the beginning of the 21st century until today, the demand for lighting systems includes not only visual parameters (brightness, contrast perception, color quality), but also non-visual parameters. It is necessary to define the new non-visualparameters for the realization of the new concept of Human Centric Lighting (HCL) or Integrative Lighting. As a contribution tothis approach, many international research groups have tried to quantify the non-visual parameters such as Circadian Stimulus by M. Rea et. al. in USA (CS2018, CS2021), Melanopic Equivalent Daylight (D65) illuminance, mEDI of the CIE S 026/E:2018 or the latest formula by Giménez et al. for the nocturnal melatonin suppression. Therefore, it is necessary to analyze the relationship between these non-visual metrics and brightness metrics such as the equivalent luminance of Fotios et al. or the latest brightness model of TU Darmstadt so that scientists, lighting engineers and lighting system users can correctly apply them in their work. In this context, this paper attempts to investigate and analyze these relationships between the three metric groups based on the database of 884 light sources of different light source technologies and daylight spectra. The obtained results show that the latest Circadian Stimulus model of M. Rea et. al. CS2021 with the improvement of Circadian Light CLA,2021 (CLA 2.0) has solved the disadvantage of CS2018, especially for the interrupted point between warm and cold white (about 3710 K) or the junction between negative and positive signal of the opponent channel (B-(L + M)). Moreover,these three metrics of the three research groups contain a high correlation coefficient, so that one metric can be transformed by linear functions to the other two parameters.

Abstract
Hydrotalcite samples were prepared in the form of powder and/or sol under different conditions and characterised by various techniques. A suitable system of liquid carriers consisting of perfluoroheptane, isopropanol, and water (PFH-IPA-H2O) was chosen to apply HTlcs as deacidifying agents to paper. The areas of miscibility and immiscibility in the PFH-IPA-H2O system were determined at a temperature of 25 °C. The properties of HTlcs dispersed in the prepared solvent were measured. The size of the particles was determined by optical microscopy with image analysis. The average particle size ranges from 1 µm to 2 µm. The settling speed of particles in the prepared colloidal systems was monitored using turbidimetry. Sols in the mixture of solvents had uniformly dispersed particles that settled slowly. The effect of the prepared colloidal HTlcs dispersions on the properties of the paper, specifically the pH of its surface, was also tested. Hydrotalcites in the form of a sol with a ratio of magnesium to aluminium of 5:1 was found to be promising candidates for deacidification. The use of surfactant additives in the preparation of HTlcs did not positively affect the properties of the paper.

Abstract
Background Suicide is a significant public health problem caused by the interaction between demographic, socio-economic, and cultural factors. According to the World Health Organization, about 804,000 fatal suicides and several times this number of suicide attempts occurred worldwide in 2017. Evidence suggests that the incidence of suicide varies among Iran provinces. It is essential to know these differences to allocate resources and adopt the right policies.Methods We used data recorded by the Ministry of Health and the National Forensic Medicine Organization during the study years to provide information about the rate of suicide attempts in the provinces of Iran. To accurately calculate the under-reporting of suicide attempts according to the frequency of successful suicide, we used TSsmooth methods in STATA 14 software. We ran Exponential, Moving Average, and H Winter models and the best model was chosen according to the lowest root mean square error.Results There were 30,137 successful suicide attempts and 349342 unsuccessful suicide attempts during the eight-year study period. Around 18,684 suicides resulted in the death of males, and 11,453 were females. Among the unsuccessful suicide attempts, 237,552 cases were males, and 111,790 were females. The incidence rate of eight years of successful suicide based on age in the age group (15–25 years) was higher than in other groups.Conclusion Considering the current situation in Iran, it is suggested that interventional measures be designed to reduce the incidence of suicide attempts, especially in the age group of 15–49 years, and to conduct pilot studies in provinces with relatively higher incidence rates than other provinces of the country.
A new method of thermal runaway warning for lithium-ion batteries using the swelling force

Published: May 2023

Abstract
The thermal runaway process of a battery is accompanied by changes in the characteristic parameters, including the battery voltage, temperature, internal resistance, gas, smoke, and swelling force, which provide many options for the early warning of battery thermal runaway. Among the various feasible warning methods for thermal runaway, the method of swelling force may have distinct advantages in advance warning and warning reliability. In this paper, commercial lithium iron phosphate/graphite and ternary/graphite batteries were used as the research objects. The patterns of the change of the swelling force with voltage, temperature, and other parameters were compared, and the results showed that the change of the swelling force during thermal runaway was higher than that during normal charging and discharging. Moreover, the time when the change of the swelling force in the thermal runaway process exceeded the change under normal working conditions was earlier, so an earlier warning could be achieved. In addition, compared with the temperature signal, the collection of the swelling force signal was more convenient. In summary, this paper provides a feasible and fast method for the early warning of battery thermal runaway, which has high engineering significance for improving the safety of electric vehicles.
Dynamic responses and interactive failure mechanisms of carbon fiber composite face sheets/double-layer corrugated core sandwich structures under low-velocity impacts loading

Abstract

A single-layer and double-layer corrugated core sandwich structure consisting of carbon fibre–reinforced polymer (CFRP) panels and aluminium alloy core layers was designed. Numerical simulations were carried out in HyperMesh/LsDyna, and the simulation results of single-layer and double-layer corrugated sandwich structure were compared with the experimental results to verify the reliability of the proposed numerical model. Compared with the results of single-layer and double-layer corrugated sandwich structure, the superiority of a double-layer corrugated sandwich structure in anti-collision performance is verified. Considering the effects of impact energy and impact position on impact force, energy absorption capacity, and failure mode, a series of low-velocity impact finite element simulations was carried out. It was found that the main failure mode of composite laminates included fibre damage, matrix damage and delamination, and core buckling. At the same impact position, the higher the impact energy, the greater the initial slopes of the contact force-time and absorbed energy-time curves, the higher the peak force, and the larger the energy absorption capacity. Under the same impact energy, when the impactor hit the wave crest of the sandwich structure, the damage to the structure was small; however, the maximum impact force on the structure was large (~8 kN).
High resolution simulation of basilar artery infarct and flow within the circle of Willis

Published: May 2023

Abstract
On a global scale, cerebro-and cardiovascular diseases have long been one of the leading causes of death and disability and their prevalence appears to be increasing in recent times. Understanding potential biomarkers and risk factors will help to identify individuals potentially at risk of suffering an ischemic stroke. However, the widely variable construction of the cerebral vasculature makes it difficult to provide a specific assessment without the knowledge of a patient’s physiology. In this paper we use the 3D blood flow simulator HemeLB to study flow within three common structural variations of the circle of Willis during and in the moments after a blockage of the basilar artery. This tool, based on the lattice Boltzmann method, allows the 3D flow entering the basilar artery to be finely controlled to replicate the cessation of blood feeding this particular vessel-we demonstrate this with several examples including a sudden halt to flow and a gradual loss of flow over three heartbeat cycles. In this work we start with an individualised 3D representation of a full circle of Willis and then construct two further domains by removing the left or right posterior communicating arteries from this geometry. Our results indicate how, and how quickly, the circle of Willis is able to redistribute flow following such a stroke. Due to the choice of infarct, the greatest reduction in flow was observed in the posterior cerebral arteries where flow was reduced by up to 70% in some cases. The high resolution domains used in this study permit the velocity magnitude and wall shear stress to be analysed at key points during and following the stroke. The model we present here indicates how personalised vessels are required to provide the best insight into stroke risk for a given individual.

Abstract
Collagenase Clostridium histolyticum (CCh), the first approved non-surgical treatment for Peyronie’s disease (PD), was withdrawn from the European, Canadian, and Asian markets due to poor demand and lack of government reimbursement options. We sought to assess insurance approval rates and usage of CCh across Canada to understand the factors that led to its withdrawal. Data on patients prescribed CCh for PD or Dupuytren's contracture was obtained through collaboration with BioScript Solutions to assess the association of variables with insurance approval and prescription filling. We identified 3297 insurance coverage applications for Xiaflex from April 2018 to June 2020. Of all applications for PD, 92.9% applications were approved while 7.1% were rejected. Despite the withdrawal of CCh from Canadian markets, coverage application approval rates for 2018, 2019, and 2020 were 86.5%, 90.1%, and 89.1%, respectively. Of 2921 approved applications, 88.8% prescriptions were filled. For the 376 rejected applications, 66.4% of prescriptions were filled. Overall, 90% of the cost of Xiaflex was covered in Canada among those with extended health benefits, with an out-of-pocket expense of $210.4. Insurance coverage requests for Xiaflex were approved at a high rate in Canada with approved patients being very likely to proceed with therapy, despite interprovincial variation.
CUI-Net: A Correcting Uneven Illumination Net for Low-Light Image Enhancement

Published: May 2023

Abstract
Uneven lighting conditions often occur during real-life photography, such as images taken at night that may have both low-light dark areas and high-light overexposed areas. Traditional algorithms for enhancing low-light areas also increase the brightness of overexposed areas, affecting the overall visual effect of the image. Therefore, it is important to achieve differentiated enhancement of low-light and high-light areas. In this paper, we propose a network called Correcting Uneven Illumination Network (CUI-Net) with sparse attention transformer and convolutional neural network(CNN) to better extract low-light features by constraining high-light features. Specifically, CUI-Net consists of two main modules: a low-light enhancement module and an auxiliary module. The enhancement module is a hybrid network that combines the advantages of CNN and Transformer network, which can alleviate uneven lighting problems and enhance local details better. The auxiliary module is used to converge the enhancement results of multiple enhancement modules during the training phase, so that only one enhancement module is needed during the testing phase to speed up inference. Furthermore, zero-shot learning is used in this paper to adapt to complex uneven lighting environments without requiring paired or unpaired training data. Finally, to validate the effectiveness of the algorithm, we tested it on multiple datasets of different types, and the algorithm showed stable performance, demonstrating its good robustness. Additionally, by applying this algorithm to practical visual tasks such as object detection, face detection, and semantic segmentation, and comparing it with other state-of-the-art low-light image enhancement algorithms, we have demonstrated its practicality and advantages.

Abstract
The success of coral reef rehabilitation practices is highly variable among projects and depends, in many cases, on their survivorship. While most research studies have focused on the long-term survival and growth rates of transplanted corals, short-term coral detachment is one of the principal causes of mortality in rehabilitation practices. Nonetheless, it is possible to prevent this by increasing the speed of coral self-attachment. To address this issue, we tested the efficiency of three different fasteners in attaching loose coral fragments onto two artificial substrata by assessing coral self-attachment and detachment rates in a short-term period (90 days). We transplanted 515 coral fragments from 8 species onto two substrates (glass bottles and iron rebar) using three fasteners (nylon cable tie, metal wire, and hemp rope). Generalized Linear Mixed-effect Models showed that the type of fastener, substrate, and the interactions between them were the main determinants of coral self-attachment and detachment. After 90 days, corals attached with cable ties exhibited lower detachment rates (3.80%) than corals attached with metal wire (25.28%) or hemp rope (69.27%). A higher number of fragments secured with cable ties managed to self-attach (73.42%) and grow over the substrate, compared with those secured with metal wire and hemp rope (57.3% and 30.18%, respectively).

Abstract
Objectives This study analyzed the effect of tafluprost on endothelial function-related molecules and hemorheological parameters in patients with primary open-angle glaucoma, and provided reference for clinical treatment.Methods Patients with primary open-angle glaucoma diagnosed and treated in our hospital from January 2018 to March 2019 were selected as the research subjects. 70 patients (140 eyes) were randomly divided into two groups: control group (n = 35 cases, 70 eyes) and observation group (n = 35 cases, 70 eyes). The patients in the control group received timolol maleate eye drops, and the patients in the observation group received tafluprost eye drops. The clinical effects of the two groups of patients were analyzed, and the changes of endothelial function-related molecule [vascular endothelial growth factor (VEGF) level] were detected before and after treatment, and the changes of blood rheology parameters before and after treatment in the two groups were analyzed.Results The total effective rate of the observation group was significantly higher than that of the control group (P < 0.05). After treatment, the visual acuity of the two groups was significantly increased while the intraocular pressure (IOP) was significantly decreased (P < 0.05), and the levels of VEGF and its receptors in serum were significantly increased (P < 0.05), End diastolic velocity (EDV) and peak systolic velocity (PSV) levels of central retinal artery (CRA) and short posterior ciliary artery (SPCA) were significantly increased while resistance index (RI) level was significantly decreased (P < 0.05). Compared with the control group, the above indicators in the observation group had more significant changes (P < 0.05).Conclusions Tafluprost has obvious clinical effect on patients with primary open-angle glaucoma, and can significantly improve abnormal hemorheological parameters and abnormal levels of endothelial function molecules.
