AbstractBackgroundStereotactic body radiotherapy (SBRT) is a well‐established treatment modality for liver metastases in patients unsuitable for surgery. Both CT and MRI are useful during treatment planning for accurate target delineation and to reduce potential organs‐at‐risk (OAR) toxicity from radiation. MRI‐CT deformable image registration (DIR) is required to propagate the contours defined on high‐contrast MRI to CT images. An accurate DIR method could lead to more precisely defined treatment volumes and superior OAR sparing on the treatment plan. Therefore, it is beneficial to develop an accurate MRI‐CT DIR for liver SBRT.PurposeTo create a new deep learning model that can estimate the deformation vector field (DVF) for directly registering abdominal MRI‐CT images.MethodsThe proposed method assumed a diffeomorphic deformation. By using topology‐preserved deformation features extracted from the probabilistic diffeomorphic registration model, abdominal motion can be accurately obtained and utilized for DVF estimation. The model integrated Swin transformers, which have demonstrated superior performance in motion tracking, into the convolutional neural network (CNN) for deformation feature extraction. The model was optimized using a cross‐modality image similarity loss and a surface matching loss. To compute the image loss, a modality‐independent neighborhood descriptor (MIND) was used between the deformed MRI and CT images. The surface matching loss was determined by measuring the distance between the warped coordinates of the surfaces of contoured structures on the MRI and CT images. To evaluate the performance of the model, a retrospective study was carried out on a group of 50 liver cases that underwent rigid registration of MRI and CT scans. The deformed MRI image was assessed against the CT image using the target registration error (TRE), Dice similarity coefficient (DSC), and mean surface distance (MSD) between the deformed contours of the MRI image and manual contours of the CT image.ResultsWhen compared to only rigid registration, DIR with the proposed method resulted in an increase of the mean DSC values of the liver and portal vein from 0.850 ± 0.102 and 0.628 ± 0.129 to 0.903 ± 0.044 and 0.763 ± 0.073, a decrease of the mean MSD of the liver from 7.216 ± 4.513 mm to 3.232 ± 1.483 mm, and a decrease of the TRE from 26.238 ± 2.769 mm to 8.492 ± 1.058 mm.ConclusionThe proposed DIR method based on a diffeomorphic transformer provides an effective and efficient way to generate an accurate DVF from an MRI‐CT image pair of the abdomen. It could be utilized in the current treatment planning workflow for liver SBRT.

AbstractPurposeTo study implant lead tip heating because of the RF power deposition by developing mathematical models and comparing them with measurements acquired at 1.5 T and 3 T, especially to predict resonant length.Theory and MethodsA simple exponential model and an adapted transmission line model for the electric field transfer function were developed. A set of wavenumbers, including that calculated from insulated antenna theory (King wavenumber) and that of the embedding medium were considered. Experiments on insulated, capped wires of varying lengths were performed to determine maximum temperature rise under RF exposure. The results are compared with model predictions from analytical expressions derived under the assumption of a constant electric field, and with those numerically calculated from spatially varying, simulated electric fields from body coil transmission. Simple expressions for the resonant length bounded between one‐quarter and one‐half wavelength are developed based on the roots of transcendental equations.ResultsThe King wavenumber for both models more closely matched the experimental data with a maximum root mean square error of 9.81°C at 1.5 T and 5.71°C at 3 T compared to other wavenumbers with a maximum root mean square error of 27.52°C at 1.5 T and 22.01°C for 3 T. Resonant length was more accurately predicted compared to values solely based on the embedding medium.ConclusionAnalytical expressions were developed for implanted lead heating and resonant lengths under specific assumptions. The value of the wavenumber has a strong effect on the model predictions. Our work could be used to better manage implanted device lead tip heating.

Authors: Turpault Rodolphe 
Published: May 2024

AbstractThe space‐time generalized Riemann problems method allows to obtain numerical schemes of arbitrary high order that can be used with very large time steps for systems of linear hyperbolic conservation laws with source term. They have been introduced in Berthon et al. (J. Sci. Comput. 55 (2013), 268–308.) in 1D and on 2D unstructured meshes made of triangles. The objective of this article is to complement them in order to answer some important questions arising when they are involved. The formulation is described in detail on quadrangle meshes, the choice of approximation basis is discussed and Legendre polynomials are used in practical cases. The addition of a limiter to preserve certain properties without compromising accuracy is also considered. Finally, the asymptotic behavior of the scheme in the diffusion regime is studied.

AbstractObjectiveMetabolic dysfunction‐associated steatotic liver disease (MASLD) is becoming an escalating health problem in pediatric populations. This study aimed to investigate the role of N‐acetyltransferase 10 (NAT10) in maternal high‐fat diet (HFD)‐induced MASLD in offspring at early life.MethodsWe generated male hepatocyte‐specific NAT10 knockout (Nat10HKO) mice and mated them with female Nat10fl/fl mice under chow or HFD feeding. Body weight, liver histopathology, and expression of lipid metabolism–associated genes (Srebp1c, Fasn, Pparα, Cd36, Fatp2, Mttp, and Apob) were assessed in male offspring at weaning. Lipid uptake assays were performed both in vivo and in vitro. The mRNA stability assessment and RNA immunoprecipitation were performed to determine NAT10‐regulated target genes.ResultsNAT10 deletion in hepatocytes of male offspring alleviated perinatal lipid accumulation induced by maternal HFD, decreasing expression levels of Srebp1c, Fasn, Cd36, Fatp2, Mttp, and Apob while enhancing Pparα expression. Furthermore, Nat10HKO male mice exhibited reduced lipid uptake. In vitro, NAT10 promoted lipid uptake by enhancing the mRNA stability of CD36 and FATP2. RNA immunoprecipitation assays exhibited direct interactions between NAT10 and CD36/FATP2 mRNA.ConclusionsNAT10 deletion in offspring hepatocytes ameliorates maternal HFD‐induced hepatic steatosis through decreasing mRNA stability of CD36 and FATP2, highlighting NAT10 as a potential therapeutic target for pediatric MASLD.

Published: May 2024

AbstractThree‐dimensional graphene architecture (3DGA) as reinforcement with successive reinforcement effect has attracted intense attention in the field of polymer composites, while 3DGA also faces the disadvantages of weak interfacial adhesion with matrices. The surface decoration of 3DGA with molybdenum disulfide (3DGA@MoS2) further promoted the diffusion and penetration of epoxy molecular for 3DGA network with the aid of resin transfer molding (RTM) technic. The MoS2 transition nanolayer not only forms covalent bonding with 3DGA but mechanical interlocks with epoxy, which effectively improved the interface combination in composite. Compared with neat epoxy, the glass transition temperature (Tg) and tensile strength increased by 18°C and 58.6%, as well as the average friction coefficient and wear rate decreased by 84% and 89%, respectively, by low loading of only 2 wt% 3DGA@MoS2. Hence, the 3D graphene modified strategy by surface decoration provides a new insight for manufacturing high‐performance epoxy‐graphene composites with excellent tribological properties.Highlights
A highly ordered and interconnected 3DGA reinforcement was fabricated.
MoS2 serves as interlayer, forming covalent bond and mechanical interlock.
Incorporation of 3DGA@MoS2 enables rapid heat conduction and load transfer.
Bi‐interpenetrating 3D structure/polymer network endows good wear resistance.
Improved comprehensive properties ascribe to strong interface adhesion.

Understanding epidemiology of injuries is important to identify treatment and prevention strategies.ObjectiveTo describe injury rates and patterns in U.S. high school track and field throwing events from a longitudinal national sports injury surveillance system.DesignDescriptive epidemiology study.SettingData were provided by the National High School Sports Related Injury Surveillance System, High School RIO (Reporting Information Online).MethodsAthletic trainers reported injury and exposure data through the High School RIO website on a weekly basis. An athlete exposure (AE) was defined as one athlete participating in one school‐sanctioned practice or competition. Throwing events of discus, shot put, and javelin were analyzed in this study.Main Outcome MeasuresInjury rate, rate ratios (RR), injury proportion ratios (IPR).ParticipantsU.S. high school athletes.ResultsA total of 267 track and field throwing injuries occurred during 5,486,279 AEs. Overall, the rate of injuries in competition was higher than in practice (RR 1.35, 95% confidence interval [CI] 1.01–1.80). In practice, the rate of injuries was higher for girls than boys (RR 1.53, 95% CI 1.12–2.08). The most frequently injured body part was the shoulder (21.7%), followed by the ankle (16.5%) and knee (12.0%). The most common types of injury were muscle strains (26.14%) and ligament sprains (25%). Recurrent injuries accounted for a higher proportion of chronic injuries compared to new injuries (IPR 1.85, 95% CI 1.16–2.97).ConclusionThis study described injury characteristics of high school track and field throwing athletes from 2008 to 2019. Based on our results, injury prevention may be particularly important for female throwers with prior injury.

Published: May 2024

The Cu–Zr‐based metallic glasses (MGs) have recently sparked great attention due to their outstanding properties and their improved glass‐forming ability (GFA). Therefore, a molecular dynamics study is performed to investigate the effect of composition on the structural analysis methods including the radial distribution function, Voronoi analysis, and coordination number of three Cu‐Zr‐Al alloys to predict the system having the much higher GFA. The T–V curves during the cooling process involve transitioning the liquid state to the glassy state, demonstrating that and are good glass formers. The findings reveal that the splitting of the second peak in the radial distribution function at results in more pronounced one. It is also indicated that with increasing Al content, the system undergoes a decrease toward the CN. Additionally, higher Al content contributes to the higher content of the full icosahedra as well as the distorted icosahedra, consequently, higher GFA. These structures, demonstrate various modes of linkage including vertex sharing, edge sharing, face sharing, and interpenetrating sharing, resulting in more dense atomic packing. Finally, strong correlations between the atomic compositions with the structural properties are shown, which can help to predict the much higher GFA system.

Published: May 2024

AbstractUpgrading thermosetting polymer waste and harvesting unwanted electromagnetic energy are of great significance in solving environmental pollution and energy shortage problems. Herein, inspired by the glass‐blowing art, a spontaneous, controllable, and scalable strategy is proposed to prepare hollow carbon materials by inner blowing and outside blocking. Specifically, hierarchically neuron‐like hollow carbon materials (HCMSs) with various sizes are fabricated from melamine‐formaldehyde sponge (MS) waste. Benefiting from the synergistic of the hollow “cell body” and the connected “protrusions” networks, HCMSs reveal superior electromagnetic absorption performance with a strong reflection loss of −54.9 dB, electromagnetic‐heat conversion ability with a high conversion efficiency of 34.4%, and efficient energy storage performance in supercapacitor. Furthermore, a multifunctional device integrating electromagnetic‐heat‐electrical energy conversion is designed, and its feasibility is proved by experiments and theoretical calculations. The integrated device reveals an output voltage of 34.5 mV and a maximum output power of 0.89 µW with electromagnetic radiation for 60 s. This work provides a novel solution to recycle polymer waste, electromagnetic energy, and unwanted thermal energy.

Published: May 2024

AbstractLarge amounts of small molecule dyes leak into the ecosystems annually in harmful and unsustainable ways. Polymer dyes have attracted much attention because of their high migration resistance, excellent stability, and minimized leakage. However, the complex synthesis process, high cost, and poor degradability hinder their widespread application. Herein, green and sustainable polymer dyes are prepared using natural dye quercetin (Qc) and CO2 through a one‐step process. The CO2‐sourced polymer dyes show strong migration resistance, high stability, and can be degraded on demand. Additionally, the CO2‐sourced polymer dyes showed unique responses to Zn2+, leading to significantly enhanced fluorescence, highlighting their potential for information encryption/decryption. The CO2‐sourced polymer dyes can solve the environmental hazards caused by small molecule dye leakage and promote the carbon cycle process. Meanwhile, the one‐step synthesis process is expected to achieve sustainable and widespread utilization of CO2‐sourced polymer dyes.

AbstractThis study focuses on assessing the seasonal variation in groundwater quality within the Al‐Hoceima region, specifically examining physicochemical parameters and bacteriological indicators of water fecal contamination. The sampling campaign took place during the wet and dry seasons of 2019 and 2021. In situ measurements were conducted on 37 groundwater samples to determine the physicochemical parameters, while bacteriological analyses were performed using Escherichia coli (E. coli) as a fecal contamination indicator. The findings demonstrate significant variations in physicochemical parameters across seasons and reveal fecal contamination of the groundwater, predominantly indicated by increased levels of E. coli during wet periods. Possible contributing factors include water surface runoff and percolation processes. Additionally, the result showed a high concentration of E. coli expected 240 CFU/100 mL. Pollution was higher in the dry season than in the wet season. These results underscore the poor quality of the water in the Al Hoceima region, necessitating treatment before consumption.

Published: May 2024

AbstractGeneration Z are the young people born and grown up in the age of social media and digital technology, within the Internet era and who are currently in the higher education-to-work transition phase. It is the generation that makes its first working steps in a global economic environment heavily affected by Covid-19 consequences and digital transformation’s influence. Empirical studies conducted provide results that vary across national cultures indicating the need for research in different countries, especially when it comes to Greek Generation Z for which little is known. This study contributes by providing a new approach when investigating entrepreneurial intention, by investigating Greek university students’ work values and grit. A convenience sample of 255 business administration students were surveyed in terms of their entrepreneurial intention. Grit, extrinsic and intrinsic work values, alongside social values are studied to understand student entrepreneurial intention, while results indicate that only grit has a positive and statistically significant effect on entrepreneurial intention. Results are useful for higher education’s stakeholders and for employers seeking to attract and to effectively integrate Generation’s Z employees to their organizations.

Authors: Gottlichova Marcela 
Published: May 2024

AbstractThe period of the pandemic crisis in the Czech Republic significantly reflected the uncertainty of the time. It was characterized by the loss of the guarantee for the services of non-governmental non-profit organizations, which the public will demand and accept in the future. The period coincided with financial impacts on the running of these organizations, declining public confidence, and declining interest from supporters. The presented study, based on the secondary and mainly primary data reflecting the attitude of non-governmental non-profit organizations of the Zlin Region based on quantitative research aimed at the communication of organizations during the pandemic, has once again confirmed the still-persistent shortcomings demonstrably requiring necessary changes leading to the efficiency of the current form of communication on a professional basis. One of the ways to offer a solution to the ongoing unhappiness is the intensive cooperation of non-governmental non-profit organizations with students of marketing communications, as documented explicitly by the collaboration of the Faculty of Multimedia Communications of the Tomas Bata University in Zlin in cooperation with the Zlin Region, which enables significant assistance in the professionalization of non-governmental non-profit organizations’ communication in continuity with development of the Zlin Region on the one hand. On the other hand, it strengthens the interest in non-commercial marketing among university students in continuity with their future professional classification.
