Authors: Angelico Ruggero , Giametta Ferruccio , Bianchi Biagio , Catalano Pasquale
Published: January 2025

Green hydrogen (GH2) is emerging as a key driver of global energy transition, offering a sustainable pathway to decarbonize energy systems and achieve climate objectives. This review critically examines the state of GH2 research production technologies and their integration into renewable energy systems, supported by a bibliometric analysis of the recent literature. Produced via electrolysis powered by renewable energy, GH2 shows significant potential to decarbonize industries, enhance grid stability, and support the Power-to-X paradigm, which interlinks electricity, heating, transportation, and industrial applications. However, widespread adoption faces challenges, including high production costs, infrastructure constraints, and the need for robust regulatory frameworks. Addressing these barriers requires advancements in electrolyzer efficiency, scalable fuel cell technologies, and efficient storage solutions. Sector-coupled smart grids incorporating hydrogen demonstrate the potential to integrate GH2 into energy systems, enhancing renewable energy utilization and ensuring system reliability. Economic analyses predict that GH2 can achieve cost parity with fossil fuels by 2030 and will play a foundational role in low-carbon energy systems by 2050. Its ability to convert surplus renewable electricity into clean energy carriers positions it as a cornerstone for decarbonizing energy-intensive sectors, such as industry, transportation, and heating. This review underscores the transformative potential of GH2 in creating a sustainable energy future. By addressing technical, economic, and policy challenges and through coordinated efforts in innovation and infrastructure development, GH2 can accelerate the transition to carbon-neutral energy systems and contribute to achieving global climate goals.

Published: January 2025

Calcites before and after calcination at 1000 °C were evaluated for their potential removal of perfluorooctanoic acid (PFOA) from water. After heat treatment, the PFOA sorption capacity increased by 25%, from 3.2 to 3.9 mg g−1, and the affinity increased by 2.7 times, from 0.03 to 0.08 L mg−1. Kinetically, the initial rate, rate constant, and equilibrium sorption were 8.7 mg g−1 h−1, 2.6 g mg−1 h−1, and 1.8 mg g−1 for heat treated calcite, in comparison to 6.4 mg g−1 h−1, 3.1 g mg−1 h−1, and 1.4 mg g−1 for calcite without heat treatment. X-ray diffraction analyses showed phase changing from calcite to calcium oxide after calcination. However, after contact with PFOA solutions for 24 h, the major phase changed back to calcite with a minute amount of Ca(OH)2. These results suggest that using raw cement materials derived from heat treatment of limestone may be a good option for the removal of PFOA from water. Thus, further studies are needed to confirm this claim.
Genome-Wide Identification and Characterization of the Homeodomain Leucine Zipper Protein (HD-Zip) Gene Family in Sea Buckthorn (Hippophae rhamnoides) Under Lead Stress
Authors: Li Jiaxin , Hu Na , Sun Jing , Zhou Wu
Published: January 2025

This study investigates the role of sea buckthorn HD-Zip genes in response to lead stress, identifying 28 genes distributed across 10 chromosomes, which are classified into four subfamilies. Each subfamily exhibits a similar gene structure and conserved protein motifs. The HD-Zip gene family is notably enriched in stress-responsive elements. Transcriptomic analysis revealed differential expression among the 28 members of the HD-Zip gene family in sea buckthorn, varying with different Pb ion concentrations. Upregulated genes were predominantly observed at stress concentrations of 1 g/kg and 5 g/kg, while downregulated genes were more prevalent at the 0.5 g/kg stress concentration. Covariance analysis indicated that large-scale gene duplication was the primary mechanism driving the expansion of the sea buckthorn HD-Zip gene family. Additionally, analysis of three-dimensional protein structures demonstrated high conservation within the HD-Zip gene, suggesting that certain sea buckthorn HD-Zip proteins may play significant regulatory roles in physiological functions. Scanning electron microscopy–energy-dispersive spectroscopy (SEM-EDS) analysis revealed that the majority of lead ions accumulated in the roots of the seedlings, with the lead concentration affecting the number, density, and function of leaf slits. These findings enhance our understanding of the complex regulatory mechanisms governing HD-Zip genes and will contribute to the genetic improvement of sea buckthorn for breeding under lead stress conditions.

Published: January 2025

The article reviews the literature on antimicrobial peptides (AMPs) that exhibit unique antimicrobial mechanisms, such as broad-spectrum activity, low development of antimicrobial resistance, and the ability to modulate the immune response of the host organism. Information is provided on the significant potential of AMPs in the fight against pathogens threatening human health and food safety. Enrichment of the human diet with biologically active peptides obtained using the proteolytic activity of lactic acid bacteria (LAB) is proposed as a simple, accessible, and viable alternative to antibiotics that does not have a harmful side effect. The review briefly covers the methods for obtaining AMPs and features of the LAB proteolytic system responsible for producing bioactive peptides in the environment. It has been shown that using various LAB strains makes it possible to produce high-quality whey-based beverages with different directions of antagonistic activity against opportunistic pathogens and helps optimize the gastrointestinal microbiota. It is assumed that such drinks can reduce the dose of antimicrobials in the combined therapy of various infectious diseases and be a preventive measure against contagion and the spread of antimicrobial resistance.

Authors: Xia Yunfei , Guo Qingming , Lei Lei , Wu Jiong , Su Xin , Wu Jianxin
Published: January 2025

A new safety risk assessment model for battery pack production processes was developed using the DEMATEL-ANP method to analyze the impact and complex relationships of risk-influencing factors. Initially, five major risk-influencing factors were identified, leading to the construction of a 15-factor indicator system. Through the DEMATEL method, these factors were categorized into cause and result factors. Subsequently, by combining the DEMATEL and ANP methods, key risk-influencing factors were identified by comparing ANP weights with hybrid weights adjusted through the DEMATEL-ANP method. Finally, integrating the DEMATEL-ANP method with the fuzzy comprehensive evaluation method allowed us to assess the overall fire safety risk level. Our findings highlighted “hazards in the test process” and “fire hazards” as critical risk factors needing control and elimination in the highly hazardous battery pack production process. This method offers dynamic evaluation and valuable insights for safety management in battery pack production.
Evaluation of the Frequency of HLA-DQ2/DQ8 Genes Among Patients with Celiac Disease and Those on a Gluten-Free Diet
Authors: Kowalski Marek K. , Domżał-Magrowska Danuta , Małecka-Wojciesko Ewa
Published: January 2025

Background: Celiac disease (CD) is a chronic, permanent, gluten-dependent disease that manifests itself with inflammation of the small intestine and malabsorption in genetically predisposed individuals with HLA-DQ2 and -DQ8 (human leukocyte antigen) histocompatibility antigens. Objective: The diagnostic criteria for celiac disease have undergone numerous modifications over the years. The aim of the study is to evaluate the frequency of HLA-DQ2/DQ8 genes in a group of patients with celiac disease diagnosed in 1980–2010 in order to verify the primary diagnosis of CD. Methods: The study group included 50 patients, 13 men and 37 women, who had been diagnosed with celiac disease many years ago based on histopathological criteria and improvement of health condition after receiving a gluten-free diet. The control group consisted of 31 healthy volunteers, 18 women and 13 men. All subjects underwent a genetic analysis assessing the presence of histocompatibility antigens HLA-DQ2.2, -DQ2.5, and -DQ8, along with the assessment of alleles encoding the α and β subunits of the antigens, according to European Society of Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) guidelines from 2020, using the EUROarray technique at EUROIMMUNE®. Results: In the study group, 12 (24%) patients did not meet the genetic criteria. Among the remaining patients (Group 1) with celiac disease, the presence of HLA-DQ2.5 (50.0% vs. 9.68%; p < 0.01) and the co-occurrence of both alleles of HLA-DQ2 (31.6% vs. 6.45%; p < 0.05) were detected significantly more frequently than in the control group. Among patients with celiac disease, the prevalence of HLA-DQ8 was also slightly more frequent (13.2% vs. 3.23%; p > 0.05). Patients who did not meet the genetic criteria for celiac disease (Group 2) had a single string α-HLA-DQ2.5 significantly more often than control subjects (66.67% vs. 38.71%; p < 0.05). Conclusions: Among patients with celiac disease diagnosed before 2010, based on the 2020 ESPGHAN criteria, it is advisable to verify the previous diagnosis, taking into account genetic criteria.
Exploring Sensory Attributes in Spinach- and Offals-Filled Chicken Roulades: An Empirical Analysis
Authors: Boișteanu Paul-Corneliu , Anchidin Bianca-Georgiana , Ciobanu Marius-Mihai
Published: January 2025

One of the most significant industries in the world is the meat sector, and development into new goods is ongoing due to high customer demand and fierce market competition. Products made from chicken are widely favored. This phenomenon can be attributed to the lack of cultural or religious restrictions on this meat. The study looks into how using two distinct types of iron-rich fillings impacts the sensory profile of classic chicken roulades. The purpose of the study is to determine how changes in sensory qualities (such as taste, texture, and flavor) affect product acceptance among customers. This approach uses methods like check-all-that-apply (CATA), principal component analysis (PCA), external preference mapping (PrefMap), and penalty analysis to explore the impact of adding chicken offals and spinach as fillings on the sensory profile of traditional chicken meat roulades. This approach seeks to expand the meat product category, create new goods that use both plant and animal components, invent new ways to use offals and spinach in the market, and ensure that consumers accept these new products. Based on the results of our investigation, the type of filling utilized in the roulades showed the most differences across all sensory tests. According to hedonic analysis and preference mapping (PrefMap), the majority of customers favored roulades with spinach fillings as opposed to those containing chicken offals, which only a small portion of customers liked. Variations in consumer preference for roulades filled with chicken offals were noted in the anatomical region, with slightly greater preference for roulades made from chicken breast. However, this (anatomical region used) did not significantly affect the outcomes of all sensory tests. The spinach stuffing was found to be quite popular with the customers, even outperforming traditional chicken roulades, making it the most significant influence. Based on consumer appreciation, this suggests that the spinach-filled chicken roulades may be a viable option for meat products in the future.

Published: January 2025

The aim of this work was to characterize the quality of meat from hares (Lepus europaeus Pallas), namely, the fatty acid content, health lipid indices, and instrumental, histological, and sensory profiles by gender and muscle type (Longissimus dorsi/LD vs. Semimembranosus/SM). The ΣPUFA/Σ SFA was higher for males, with an average value of 1.62/1. The Σn6/n3 ratio was elevated for males, with a mean value of 5.34/1. The mean meat essential fatty acids were 41.94%, the desirable fatty acids were 77%, and the polyunsaturation index was 6.09. Moreover, the atherogenic index was 0.72, the thrombogenic index was 0.71, the hypocholesterolemic/hypercholesterolemic (h/H) fatty acids ratio was 3.30, and the nutritive value index was 1.35. After the sensory analysis, the LD muscles showed higher scores in males for overall appreciation (4.20 vs. 3.95) but higher scores in females for SM muscles (4.14 vs. 4.00). Shear force was influenced by the ratio between muscle and connective tissue, and the proportion of collagen and protein was related to the number of muscle fibers. Muscle and connective tissues are inversely proportional, and their ratio is an indicator of the textural and mechanical properties of the analyzed samples. Hare meat is an appreciated resource for consumers in terms of its sensory, instrumental, and nutritional values, and it has a higher value than that obtained from livestock species or other wild animals (more valuable proteins, lower fat content, and better health lipid indices).
Floral Regulation: The Significant Virtue of Horticultural Flowering Plants
Authors: Khan Faiza Shafique , Ning Chong-Yang , Li Zhuang-Zhuang , Hu Chun-Gen , Zhang Jin-Zhi
Published: January 2025

Flowering is a complex developmental mechanism and is essential for successful reproduction in plants. Complex regulatory networks transform vegetative shoot apical meristems into inflorescence meristems. Further, floral meristems transition to floral bud outgrowth and flowering. Floral regulatory pathways are independently involved in flowering, and most of what we know about genetic regulation comes from model plants. Despite the advancements in plant development biology, the understanding of molecular mechanisms and floral signals in horticultural plants is complex. Studies on gene regulatory mechanisms provide a global view of flowering in horticultural plants. In this paper, we discuss the flowering pathways converging on complex gene regulatory mechanisms and summarize the recent findings in horticultural plants in order to help us understand how they regulate flowering and provide an update for future research.

Authors: Tetiker Sibel , Akdogan Hacer Nida , Alpay Nilgun , Dogan Muharrem Cem
Published: January 2025

Background/Objective: Throat packs are widely used during orofacial surgery to reduce the frequency of postoperative nausea and vomiting (PONV). However, evidence supporting their use is mixed, with associated risks such as postoperative sore throat and the possibility of being forgotten in situ. Methods: The aim of this study is to evaluate the effectiveness of throat packs in preventing PONV and postoperative sore throat during dental treatments under general anesthesia in children with special healthcare needs (SHCNs). Eighty children with SHCNs were randomized into two groups: throat packing (Group TP, n = 41) and no throat packing (Group n-TP, n = 39). A throat pack was used in Group TP, and PONV and sore throat were evaluated at 1, 2, and 4 h postoperatively. Statistical Package for Social Sciences (SPSS) version 23.0 was used for data analysis. The registration number at ClinicalTrials.gov is NCT06169306, registered on 28 December 2023. Results: Patients in Group n-TP showed significantly higher PONV values at 1 and 2 h postoperatively (p < 0.001, p = 0.019, respectively). Visual Analog Scale (VAS) values were also significantly higher in Group TP at 1 and 2 h postoperatively (p < 0.001, p = 0.002, respectively). Conclusions: Using throat packs in dental treatments under general anesthesia for children with SHCNs reduced the incidence of PONV but increased the incidence of postoperative sore throat.

Published: January 2025

Background: Aneurysmal subarachnoid hemorrhage (aSAH) carries significant mortality and disability rates, with rebleeding posing a grave risk, particularly in anterior communicating artery (AcoA) aneurysms. This retrospective study aims to analyze preoperative and intraoperative variables of patients with ruptured AcoA aneurysms, evaluating the association of these variables with patient outcomes using machine learning techniques, proposing a prognostic score. Materials and Methods: A retrospective study was conducted on 50 patients who underwent microsurgical clipping for a ruptured AcoA aneurysm at San Giovanni Bosco Hospital, Turin, Italy. The clinical and aneurysmal data—including clinical evaluations, risk factors, aneurysmal characteristics, and intra- and postoperative details—were examined. The study population was analyzed using machine learning techniques such as the MRMR algorithm for feature selection, and the LASSO method was employed to construct linear predictive models based on these features. Results: The study cohort had a mean age of 54 years, with 26 female and 24 male patients. Temporary clipping of main vessels was performed in 96% of procedures, with a mean duration of 3.74 min. Postoperatively, the mean Intensive Care Unit (ICU) stay was 7.28 days, with 14% mortality at 30 days and 4% within the first week. At the six-month follow-up, 63% of discharged patients had a Glasgow outcome scale (GOS) of 5, with radiological confirmation of complete aneurysm exclusion in 98% of cases. Machine learning techniques identified the significant predictors of patient outcomes, with LASSO algorithms generating linear models to predict the GOS at discharge and at 6 months follow-up. Conclusions: Preoperative factors like the BNI score, Vasograde, and preoperative cerebral edema demonstrate significant correlations with patient outcomes post-clipping. Notably, intraoperative bleeding and extended temporary clipping durations (over 3 min) emerge as pivotal intraoperative considerations. Moreover, the AcoA prognostic score shows promise in predicting patient outcomes, discharge plans, and ICU duration.

Published: January 2025

Background/Objectives: Mental representation of spatial information relies on egocentric (body-based) and allocentric (environment-based) frames of reference. Research showed that spatial memory deteriorates as Alzheimer’s disease (AD) progresses and that allocentric spatial memory is among the earliest impaired areas. Most studies have been conducted in static situations despite the dynamic nature of real-world spatial processing. Thus, this raises the question: Does temporal order affect spatial memory? The present study, by adopting a dynamic spatial memory task, explored how the temporal order of item presentation influences egocentric and allocentric spatial judgments in individuals with early-stage Alzheimer’s disease (eAD) and healthy elderly individuals (normal controls—NC). Method: Participants were required to memorize dyads of simple 3D geometrical objects presented one at a time on a desk along with a bar. Afterwards, they had to choose what stimulus appeared either closest to them (egocentric judgment) or closest to the bar (allocentric judgment). Results: Results revealed that the temporal order significantly affected spatial judgments in eAD patients but not in NC participants. While eAD patients remain anchored to the item presented first, which is more accurate regardless of the frame used, NC are equally accurate with the item that appears first or second. This is presumably because eAD patients struggle to flexibly shift attention and update spatial representations in dynamic situations, which leads to reliance on initial information and difficulties with information presented later. Conclusions: This highlights the importance of further understanding the cognitive strategies employed by AD patients.

Background: Totally endoscopic techniques have become increasingly popular in cardiac surgery, with minimally invasive mitral valve repair emerging as an effective alternative to median sternotomy. This approach could be particularly advantageous for patients with Noonan syndrome, who often present with structural thoracic anomalies and other comorbidities like bleeding disorders. Endoscopic mitral valve surgery is rapidly establishing itself as the new standard of care for mitral valve operations, demonstrating both safety and efficacy. Noonan syndrome is an autosomal-dominant multisystem disorder with variable expression and is the second most common syndromic cause of congenital heart disease, surpassed only by Down syndrome. A wide spectrum of cardiovascular phenotypes is associated with Noonan syndrome, including pulmonary valve stenosis (often with dysplastic valves), hypertrophic cardiomyopathy, secundum atrial septal defect and mitral valve abnormalities. Methods: Given the limited data in the literature regarding the experience of other centers with endoscopic mitral surgery in patients with this condition, we aim to present the case of a 46-year-old male with a known diagnosis of Noonan syndrome who presented to a cardiologist with a 6-month history of dyspnea and fatigue. Transthoracic echocardiography revealed severe mitral regurgitation. Following multidisciplinary discussions within the Heart Team and after obtaining informed consent from the patient and his family, the decision was made to proceed with totally endoscopic mitral valve repair. Results: The patient experienced an uneventful postoperative course and was discharged 8 days after the procedure. In this case, endoscopic surgery was essential for successfully repairing the mitral valve. Structural abnormalities, such as chest wall deformities causing heart malrotation and atypical positioning, significantly impaired visualization. Conclusions: The endoscopic approach provided superior access to the mitral valve, enabling precise and effective repair. Additionally, it offered benefits such as improved esthetic outcomes, faster recovery, and a reduced risk of exacerbating thoracic deformities due to improper sternal bone healing.

Authors: Colaprico Corrado , Lomartire Francesca , Raccio Ivana , Mantione Giorgia , Ammirati Salvatore , La Torre Giuseppe
Published: January 2025

Background/Objectives: With technological development, ionizing radiation has found applications in numerous occupations. However, the determination and quantification of the damage resulting from exposure to it remains rather unclear, along with the damage to particular organs. The aim of this systematic review was to investigate the relationship between low-dose ionizing radiation (LDIR) in exposed workers and possible functional changes and cancer development in the thyroid gland. Methods: We included observational studies evidencing the correlation under study. Data extraction and analysis was conducted on all included studies. The research strategy included three electronic databases (PubMed, Scopus, and Web of Science). The systematic review followed PRISMA guidelines, and the research protocol was submitted to PROSPERO (CRD:42023425839). Results: The search initially yielded 166 articles and, once duplicates and irrelevant articles were removed, a total of 15 useful articles were reviewed. Qualitative analysis of the studies showed that the TSH value does not change following exposure, while a reduction in fT3 and an increase or reduction in fT4 can be observed. Furthermore, the correlation between thyroid cancer and occupational exposure to radiation was not shown with certainty, but there was some evidence of increased gland volume and nodule formation. Conclusions: Even at low doses, ionizing radiation adversely affects thyroid activity. In this regard, new studies should be carried out in order to further investigate and define this issue and, consequently, outline useful measures to ensure the protection of workers in contact with this particular physical agent.

Published: January 2025

Cardioneuroablation is a rapidly developing procedure for the treatment of vagally mediated bradyarrhythmias. However, the lack of multicenter, randomized trials prevents it from being included in bradyarrhythmia treatment guidelines. So far, only one small, randomized study has been published assessing the effectiveness of this method in the treatment of reflex syncope. This is a brief review of ongoing randomized trials evaluating the effectiveness and safety of cardioneuroablation for the treatment of functional bradyarrhythmias.
Effect of Open-Wedge High Tibial Osteotomy and Lateral Retinacular Release on the Articular Cartilage of the Patellofemoral Joint: Analysis Using Magnetic Resonance Imaging T2 Mapping
Authors: Nakagawa Shuji , Kan Hiroyuki , Arai Yuji , Komaki Shintaro , Hino Manabu , Inoue Atsuo , Takahashi Kenji
Published: January 2025

Background/Objectives: After open-wedge high tibial osteotomy (OWHTO), the patella is displaced distally, causing patellofemoral joint degeneration. The objective of this study was to ascertain whether the combination of OWHTO and lateral retinacular release (LRR) can prevent articular cartilage degeneration of the patellofemoral joint using magnetic resonance imaging T2 mapping. Methods: This study included 37 patients (37 knees) who underwent OWHTO alone (OWHTO group) and 37 patients (37 knees) who underwent OWHTO with LRR (OWHTO + LRR group) with a correction angle of <10° for varus knee osteoarthritis. MRI was performed on all knees prior to and 6 months after surgery to assess the patellar cartilage in sagittal images for T2 mapping. Three regions of interest, (the medial facet, patellar ridge, and lateral facet), were established for the articular cartilage on the patellar side. The T2 values were subsequently quantified. Lower limb alignment, patellar height, patellar tilt angle, and lateral shift ratio were evaluated pre-and post-surgery. Results: Mean T2 values at 6 months post-surgery of the medial facet and patellar ridge of the OWHTO group showed a significant increase after surgery; no significant changes were observed in either region in the OWHTO + LRR group. In both groups, a significant decrease in patellar tilt angle was observed postoperatively; no change was noted in the lateral shift ratio or congruence angle. The change in patellar tilt angle was significantly lower in the OWHTO + LRR group than in the OWHTO group. Conclusions: LRR combined with OWHTO prevented patellofemoral joint cartilage degeneration after surgery in cases of varus knee osteoarthritis.
The Role of Body Image Perception on a Continuum from Dysfunctional to Healthy Eating Attitudes and Behaviors Among People Seeking Treatment
Authors: Bourbeau Francisca , Bouchard Stéphane , Corno Giulia , Monthuy-Blanc Johana
Published: January 2025

Background: Body image disturbance has been associated with various health conditions and has the potential to trigger the development of unhealthy behaviors, including dysfunctional attitudes and eating behaviors, which may evolve into eating disorders. This study explores the relationship between body image variables—such as global self-worth, physical self-worth, and physical attractiveness—and the continuum of eating attitudes and behaviors. Methods: A canonical correlation analysis was performed to assess the multivariate relationship between attitudinal and perceptual variables and the continuum of eating behaviors, with a total of 113 cases analyzed. Results: The findings indicate that intuitive eating and a positive body image (including global self-worth and physical attractiveness) are most strongly associated with the functional end of the continuum, while disordered eating behaviors and body dissatisfaction are linked to the dysfunctional end. Conclusions: These results suggest that interventions targeting the emotional and attitudinal dimensions of body dissatisfaction, whether delivered in vivo or via virtual reality (e.g., weight exposure), may facilitate a shift toward healthier, more functional eating behaviors along the continuum.

Authors: Kabelka David , Konvalina Petr , Kopecký Marek , Klenotová Eva , Šíma Jaroslav
Published: January 2025

Organic matter has a very important function in soil, without which, soil formation processes cannot take place properly. It can be divided and classified based on several aspects; the most general division is between the living and non-living parts of organic matter. The results presented in this paper specifically refer to the living microbial part of organic matter. This research was carried out in the years 2021–2024 in the South Bohemia region located in the Czech Republic. Two types of land use (four permanent grassland areas, two forest areas) were evaluated. Based on laboratory soil analyses, some significant dependencies were found. For example, in grasslands with statistically identical pH, there was a dependence (p-value 0.05) between soil organic carbon (SOC), carbon of microbial biomass (MBC) and microbial basal respiration (MBR). Additionally, coniferous forest experimental locations had a lower pH, which, in turn, slowed the activity of microorganisms and promoted the accumulation of SOC in the soil. The results from this experiment support the current knowledge of organic matter and are important for a better understanding of the soil organic matter cycle.

Background: Many European countries’ epidemiological data on burns were analyzed. This research aimed to analyze the key epidemiological characteristics of hospitalized burn patients in Serbia’s major burn unit over 10 years, as well as to create the very first national epidemiological dataset with the basic requirements for future epidemiological studies. Methods: A retrospective cross-sectional study was conducted, and demographic, clinical, and burn characteristics, as well as predictors of mortality, were analyzed. Results: A total of 996 patients were included. The mean age of the population was 54.65 ± 27.15 years. Regarding etiology, flame was the most common (49.0%). Patient comorbidities were noted on admission in 50.1% of cases. The mean % of total burn surface area (TBSA) was 16.89 ± 18.72%. Inhalation injury was confirmed in 7.5% of patients, and a total of 10.3% of patients required mechanical ventilation during hospitalization. The requirement for mechanical ventilation support was the strongest independent predictor of mortality, while other independent predictors of mortality were male gender, higher %TBSA, deep burns, mechanism of injury, an extended total length of stay (LOS), the occurrence of complications during hospitalization, and conservative treatment modalities. Conclusion: Burn injury mortality remains high, and %TBSA, burn depth, mechanical ventilation requirement, inhalation injury, and the presence of comorbidities on admission unfavorably influence mortality rates.

Published: January 2025

This study aims to investigate the influence of cadmium (Cd) speciation transformation on P-wave velocity under different soil moisture conditions, providing critical insights into the subsurface characteristics of contaminated soils. Taking Cd-contaminated soil as the research subject, P-wave velocity and the speciation distribution of Cd in soils with different moisture contents and Cd adsorption levels were measured. The results reveal that when the soil is contaminated by Cd, the porosity is altered and it eventually lead to change P-wave velocity. By increasing the moisture content of soils, the redox potential (Eh) rises and the pH decreases, which lead to the speciation transformation of Cd from carbonate-bound state (CAB), Fe-Mn oxide-bound state (FMO), and organic and sulfide-bound state (ORB) to the exchangeable state (EX). These transformations of Cd to EX result in the increase in soil porosity, which lead to the decrease in P-wave velocity. In addition, linear regression analysis was conducted the P-wave velocity (∆V) and the EX (∆EX) at various Cd adsorption levels. The analysis shows that there is a strong linear relationship between exchangeable Cd content and P-wave velocity, and the determination coefficient is about 0.9, which provides a reliable basis for monitoring soil Cd contamination by using P-wave velocity. This study provides valuable insights into the relationship between the speciation distribution of heavy metals in soil and the properties of acoustic wave.

Published: January 2025

Sinter-crystallization is a specific method of producing glass-ceramics that allows the manufacture of complexly shaped products, composites and solder. However, it usually is limited when the glass powders used are characterized by a high crystallization trend. This study proposes a new opportunity to improve the sinter-crystallization and demonstrates the benefits of microwave processing using diopside (CaMg(Si2O6)) glass-ceramics with an enhanced crystallinity of ~70%. The advantages of microwave processing are shown by comparing the results obtained with scanning electron microscopy, X-ray computed tomography and gas pycnometry for two glass-ceramic specimens. The first sample is obtained in the heat resistant furnace of an optical dilatometer, while the second is obtained by heating it with high-power microwave irradiation at 2.45 GHz, 1kW. Intense crystallization was observed in the sample sintered in an electric furnace, which blocked the sintering process and resulted in significant open porosity (7.1%). In addition, closed pores caused by the crystallization are observed in the centers of the sintered particles (5.2%). At the same time, the overall porosity of the microwave-sintered glass-ceramic is reduced by about two times, and the open porosity is practically eliminated (0.5%). In this sample, together with the crystallization-induced pores, some residual closed spherical pores, typical for a well-sintered sample, are also observed.

The degradation of rubber materials under environmental and mechanical stress presents a significant challenge, particularly due to UV (ultraviolet light) exposure, which severely impacts the material’s physical properties. This study aims to enhance the UV stability and longevity of rubber by evaluating the performance of modified polyurethane and silicone coatings as protective stabilizers. Natural rubber—styrene–butadiene rubber (NR-SBR), known for its exceptional mechanical properties, was selected as the base material. To ensure strong adhesion, cold atmospheric plasma treatment was applied, increasing the surface energy by 250%, primarily through an enhancement of the polar component. After treatment, supplier-recommended coatings were applied and tested for adhesion using the pull-out method. Aging tests under UV exposure, water immersion, and high temperatures were conducted to assess durability, with tensile tests used to monitor changes over time. Coatings exhibiting cracking after UV exposure were excluded from further analysis. A silicone coating demonstrating superior moisture resistance and durability under extreme conditions was identified as a promising candidate for future UV stabilization applications. These findings provide a foundation for developing advanced coatings to significantly extend the service life of rubber materials in demanding environments.

The porous structure, in which many pores are intentionally placed inside the material, has excellent impact energy absorption properties. Recent studies have attempted to fabricate multi-layered porous structures with different mechanical properties within a single porous structure sample, and the mechanical properties of these structures are being elucidated. However, these studies mainly attempted to vary the densities, pore structures, and alloy compositions within a single material, such as aluminum, for the entire sample. Since multi-materials are now being promoted to utilize the most suitable material type in the right place, porous structures made of different materials, such as a combination of aluminum and resin, are expected to be required in the future. In this study, we attempted to fabricate two-layered porous structure samples of different materials by printing a resin porous structure using a 3D printer on an aluminum foam fabricated by a precursor foaming process. Static compression tests were performed on the resulting two-layered porous structure samples to investigate their mechanical properties. The resin porous structure printed by the 3D printer and the aluminum foam were both designed to expose the porous structure on the surface of the specimen so that the deformation behavior can be easily observed. The density of the resin porous structure was varied by systematically varying the filling rate of the resin porous structure to be printed, and the effect on the compression properties was investigated. The fabricated two-layered porous structure was effectively bonded between the two layers by the anchor effect, which is a mechanical bonding caused by the resin penetrating into the pores. The layers exhibited robust bonding with no evidence of separation. It was possible to fabricate a two-layered porous structure that exhibited both properties of aluminum foam and those of resin porous structure. It was found that the plateau stress in the resin porous structure layer can be controlled between about 0.5 MPa and 40 MPa, and the deformation behavior and energy absorption properties of the two-layered porous structure can be controlled by varying the resin filling rate of the resin porous structure layer. That is, it was indicated that multi-layered porous structures with various densities and consisting of various types of materials allow for the optimal design of porous structures used in structural materials.
Quadruple-Q Skyrmion Crystal in Centrosymmetric Body-Centered Tetragonal Magnets
Authors: Hayami Satoru
Published: January 2025

We conduct a numerical investigation into the stability of a quadruple-Q skyrmion crystal, a structure generated by the superposition of four spin density waves traveling in distinct directions within three-dimensional space, hosted on a centrosymmetric body-centered tetragonal lattice. Using simulated annealing applied to an effective spin model that includes momentum-resolved bilinear and biquadratic interactions, we construct a magnetic phase diagram spanning a broad range of model parameters. Our study finds that a quadruple-Q skyrmion crystal does not emerge within the phase diagram when varying the biquadratic interaction and external magnetic field. Instead, three distinct quadruple-Q states with topologically trivial spin textures are stabilized. However, we demonstrate that the quadruple-Q skyrmion crystal can become the ground state when an additional high-harmonic wave–vector interaction is considered. Depending on the magnitude of this interaction, we obtain two types of quadruple-Q skyrmion crystals exhibiting the skyrmion numbers of one and two. These findings highlight the emergence of diverse three-dimensional multiple-Q spin states in centrosymmetric body-centered tetragonal magnets.

The advancement of Transformer models in computer vision has rapidly spurred numerous Transformer-based object detection approaches, such as DEtection TRansformer. Although DETR’s self-attention mechanism effectively captures the global context, it struggles with fine-grained detail detection, limiting its efficacy in small object detection where noise can easily obscure or confuse small targets. To address these issues, we propose Fuzzy System DNN-DETR involving two key modules: Fuzzy Adapter Transformer Encoder and Fuzzy Denoising Transformer Decoder. The fuzzy Adapter Transformer Encoder utilizes adaptive fuzzy membership functions and rule-based smoothing to preserve critical details, such as edges and textures, while mitigating the loss of fine details in global feature processing. Meanwhile, the Fuzzy Denoising Transformer Decoder effectively reduces noise interference and enhances fine-grained feature capture, eliminating redundant computations in irrelevant regions. This approach achieves a balance between computational efficiency for medium-resolution images and the accuracy required for small object detection. Our architecture also employs adapter modules to reduce re-training costs, and a two-stage fine-tuning strategy adapts fuzzy modules to specific domains before harmonizing the model with task-specific adjustments. Experiments on the COCO and AI-TOD-V2 datasets show that FSDN-DETR achieves an approximately 20% improvement in average precision for very small objects, surpassing state-of-the-art models and demonstrating robustness and reliability for small object detection in complex environments.
Effectiveness of Centrality Measures for Competitive Influence Diffusion in Social Networks

Published: January 2025

This paper investigates the effectiveness of centrality measures for the influence maximization problem in competitive social networks (SNs). We consider a framework, which we call “I-Game” (Influence Game), to conceptualize the adoption of competing products as a strategic game. Firms, as players, aim to maximize the adoption of their products, considering the possible rational choice of their competitors under a competitive diffusion model. They independently and simultaneously select their seeds (initial adopters) using an algorithm from a finite strategy space of algorithms. Since strategies may agree to select similar seeds, it is necessary to include an initial seed tie-breaking rule into the game model of the I-Game. We perform an empirical study in a two-player game under the competitive independent cascade model with three different seed-tie-breaking rules using four real-world SNs. The objective is to compare the performance of centrality-based strategies with some state-of-the-art algorithms used in the non-competitive influence maximization problem. The experimental results show that Nash equilibria vary according to the SN, seed-tie-breaking rules, and budgets. Moreover, they reveal that classical centrality measures outperform the most effective propagation-based algorithms in a competitive diffusion setting in three graphs. We attempt to explain these results by introducing a novel metric, the Early Influence Diffusion (EID) index, which measures the early influence diffusion of a strategy in a non-competitive setting. The EID index may be considered a valuable metric for predicting the effectiveness of a strategy in a competitive influence diffusion setting.
Knowledge Flow Dynamics in Organizations: A Stochastic Multi-Scale Analysis of Learning Barriers
Authors: Huang Jih-Jeng , Chen Chin-Yi
Published: January 2025

Organizations face fundamental challenges in managing knowledge flows across complex networks, yet existing frameworks often lack quantitative tools for optimization. We develop a novel stochastic multi-scale model introducing knowledge flow viscosity (KFV) to analyze organizational learning dynamics. This model quantifies resistance to knowledge transfer using a time-varying viscosity tensor, capturing both continuous learning processes and discrete knowledge acquisition events. Through renormalization group analysis, we establish the existence of critical thresholds in knowledge diffusion rates, characterizing phase transitions in organizational learning capacity. Numerical simulations demonstrate that targeted reductions in communication barriers near these thresholds can significantly enhance knowledge flow efficiency. The findings provide a mathematical foundation for understanding multi-level knowledge flow dynamics, suggesting precise conditions for effective interventions to optimize learning in complex organizational systems.
