(1) Context: Cancer is still a major problem worldwide, and traditional therapies like radiation and chemotherapy often fail to alleviate symptoms because of side effects, systemic toxicity, and mechanisms of resistance. Beneficial anticancer effects that spare healthy tissues are made possible by the distinctive redox characteristics of noble metal complexes, especially those containing palladium, gold, silver, and platinum. (2) Methods: The redox processes, molecular targets, and therapeutic uses of noble metal complexes in cancer have been the subject of much study over the last 20 years; novel approaches to ligand design, functionalization of nanoparticles, and tumor-specific drug delivery systems are highlighted. (3) Results: Recent developments include Pt(IV) prodrugs and terpyridine-modified Pt complexes for enhanced selectivity and decreased toxicity; platinum complexes, like cisplatin, trigger reactive oxygen species (ROS) production and DNA damage. Functionalized gold nanoparticles (AuNPs) improve targeted delivery and theranostic capabilities, while gold complexes, particularly Au(I) and Au(III), inhibit redox-sensitive processes such as thioredoxin reductase (TrxR). (4) Conclusions: Ag(I)-based compounds and nanoparticles (AgNPs) induce DNA damage and mitochondrial dysfunction by taking advantage of oxidative stress. As redox-based anticancer medicines, noble metal complexes have the ability to transform by taking advantage of certain biochemical features to treat cancer more effectively and selectively.

Published: February 2025

Proteus mirabilis has been identified as the third most frequent reason for catheter-associated urinary tract infections. The production of urease significantly enhances the force of catheter blockage caused by biofilm formation. Because biofilms are important virulence factors that make antibiotics less potent, it is becoming increasingly important to develop novel alternative antibiotics. In addition to the unique properties they possess, nanoparticles made from metal oxide are currently attracting considerable attention as possible antibacterials. This research aims to explore the potential anti-biofilm properties of green manufactured ZnO-CuO nanoparticles generated by P. mirabilis. By synthesizing reductive enzymes, bacterial cells can participate in the biosynthesis process. This study explores whether green synthesized ZnO-CuO nanoparticles can work as an anti-biofilm agent formed by P. mirabilis. These nanoparticles were generated using Bacteriocins to determine their effectiveness against bacteria, which were partially purified and showed antimicrobial activity against Gram-negative bacteria of P. mirabilis. AFM, TEM, FESEM, XRD, and ultraviolet (UV)–visible spectroscopy were used to analyze the biosynthesized nanoparticles to ascertain their chemical and physical characteristics. XRD verified the hexagonal structure, TEM demonstrated a size range of 96.00 nm, and FESEM verified the surface morphology. The dispersion and roughness of the nanoparticles are shown through AFM examination. The produced nanoparticles’ UV-visible spectra displayed a maximum peak at 287 and 232 nm. When applied to strains (wild-type) of Proteus mirabilis (multidrug-resistant), copper and zinc nanoparticles had notable biofilm inhibitory effects. Weak biofilm production has been demonstrated by bacteria that effectively generate biofilms, following incubation with 128 μg/mL subminimum inhibitory concentrations (MICs) of CuO nanoparticles for 24 and 48 h at 37 °C. Following treatment with the ZnO-CuO nanocomposite of these strains, downregulation alterations in LuxS expression were detected by utilizing a real-time PCR process. After this, isolates were treated with the nanocomposite, and downregulated shifts in LuxS expression were found by utilizing the real-time PCR technique in contrast with the isolates that were not treated. Zinc oxide (ZnO) nanoparticles can be utilized as antibacterial agents in a concentration-dependent manner, aligning with all observed findings. The present research demonstrates that green synthesized copper oxide–zinc oxide nanocomposites are effective anti-biofilm agents against P. mirabilis. Their noteworthy downregulation of LuxS gene expression successfully prevents biofilm formation and swarming motility.

Published: February 2025

Uneven heating is the biggest obstacle to the application of radio frequency (RF) technology in insecticidal applications. Since many existing studies have focused on the RF heating uniformity of granular materials, few RF treatment solutions have been reported for leaf materials. To improve the RF heating uniformity of tobacco leaves, a combined RF-hot air treatment method was developed for disinfestation in this study. The experiments were conducted to determine the effects of three process parameters (electrode gap, sample thickness, and hot air temperature) on the RF heating rate and uniformity of tobacco leaves. The results showed that the heating rate of RF-hot air combined treatment increased with decreasing electrode gap but increased with increasing sample thickness and hot air temperature. The RF heating uniformity in tobacco leaves decreased with increasing heating rate but could be significantly improved with the conveyor movement. Considering the heating uniformity and heating rate, the material thickness of 60 mm and electrode gap of 110 mm were selected as optimal process parameters. The results of the study may provide a feasible method to improve the RF heating uniformity in tobacco leaves and potential applications for effective disinfestations.

Authors: Wang Guandi , Wang Qian , Liu Wenrui , Wen Jingxin , Yang Yubo , Niu Zhilong , Guo Wei , Zhao Dan
Published: February 2025

The insect order Lepidoptera contains many species that are considered to be agricultural pests. Specific double-stranded RNA-degrading enzymes in some moth species decrease the efficiency of RNA interference (RNAi). RNAi refers to the efficient and specific degradation of homologous mRNA induced by highly conserved, double-stranded RNA during evolution. The dsRNase enzymes can specifically recognize exogenous dsRNA, and bind to and degrade dsRNA, resulting in the inability of dsRNA to play its role. Although dsRNases play an important role in dsRNA degradation, there has been limited research on these enzymes. In this study, we successfully identified four genes related to dsRNases (named SeRNase1, SeRNase2, SeRNase3 and SeRNase4) from the genome of Spodoptera exigua. To overcome the rapid degradation of dsRNA in the midgut of S. exigua, we combined nanotechnology with biology and developed a new strategy to administer RNAi to insect pests. This binding block directed contact between the dsRNA and SeRNases to improve the efficiency of RNAi in suppressing gene expression. We demonstrate the potential of using nanotechnology to provide a novel RNAi delivery method for pest control.
A Mid-Term Result of the Treatment of Intra-Articular Calcaneal Fractures with the Use of Intramedullary Nailing
Authors: Sypien Piotr , Grzelecki Dariusz
Published: February 2025

Background: Intra-articular calcaneal fracture (CF) treatment is associated with a high risk of complications, but closed reduction and internal fixation (CRIF) is a minimally invasive alternative for treatment. Methods: Forty-eight patients treated with CRIF and CALCAnail® due to intra-articular CF between 2016 and 2021 were analyzed to check union time, complication rate, and functionality after the intervention. Functional and pain outcomes were assessed, including the Maryland Foot Score (MFS), American Orthopedic Foot & Ankle Society (AOFAS) scale questionnaires, and the numerical pain scale (NRS) at mid-term follow-ups 2–5 years after the intervention. Results: Intervention increased median Böhler’s angle from 21.5° to 32° (p < 0.01). The median bone union time was 12 weeks. The risk of malunion was higher in patients with Sanders type 4 (RR = 2.28; 95% CI 1.11–4.72) and those operated on later than the 2nd day after injury (RR = 2.1; 95% CI 1.08–4.09). Patients with at least one of the comorbidities (nicotinism, diabetes, obesity) had a higher risk of intensive pain (NRS > 3) 2–5 years after surgery (RR = 1.69; 95% CI 1.06–2.68), and 84% were satisfied with their treatment. Other complications included complex regional pain syndrome in two patients (4%), malunion in three (6%), and surgical site infection in two (4%). The MFS had a median score of 85 points, while that of the AOFAS was 82 points. Conclusions: CRIF, with the use of the CALCAnail® implant, allows doctors to restore anatomical relationships around the subtalar joint, resulting in good clinical and functional results.

Published: February 2025

Background/Objectives: Psoriasis is a chronic immune-mediated skin disease associated with several metabolic comorbidities. Metabolic dysfunction-associated steatotic liver disease (MASLD) is also linked to psoriasis, but evidence regarding the severity of this association remains inconclusive. This meta-analysis aimed to investigate the relationship between MASLD and varying severities of psoriasis. Methods: We conducted an extensive search of four databases, MEDLINE, EMBASE, OSF, and ClinicalTrials.gov to identify relevant published articles assessing the risk of prevalent MASLD in patients with moderate-to-severe psoriasis up to April 2024. Effect estimates from each included study were combined together to calculate a pooled effect estimate for the meta-analysis using the generic inverse variance method of DerSimonian and Laird. Results: This meta-analysis included eight studies with a total of 109,806 participants. A 4.01-fold increased risk of prevalent MASLD was observed in patients with moderate-to-severe psoriasis compared to those without psoriasis (95% CI: 2.17, 7.77; I2 = 67%, p < 0.0001). The evidence supporting this outcome had low certainty. Conclusions: An incremental trend of MASLD was observed in patients with moderate-to-severe psoriasis. Routine screening for MASLD should be emphasized in this population.

Published: February 2025

Background: Angioedema (AE) is a localized, non-pitting swelling affecting subcutaneous and/or submucosal tissues. Despite varying underlying mechanisms, AE significantly impacts patients’ quality of life (QoL), which is closely linked to disease activity and control. Objectives: This study aimed to translate and linguistically validate the angioedema activity score (AAS), angioedema control test (AECT), and angioedema quality of life (AE-QoL) questionnaires into Latvian, and to use these validated tools to assess disease activity, control, and quality of life within the study population. Methods: PROMs, including the AECT, AAS, and AE-QoL, underwent a standardized linguistic validation process. Patients with hereditary angioedema (HAE), mast cell-mediated angioedema (AE-MC), and angioedema of unknown origin (AE-UNK) were recruited from two separate studies conducted at Riga Stradiņš University. Results: We enrolled 41 participants (90.2% women) with a mean age of 46.3 years. AE-MC was the most common (63.4%), followed by HAE (19.5%) and AE-UNK (17.1%). The mean AAS score was 15.8, with no significant differences regarding AE type, gender, or age. The mean AECT score was 8.29, revealing significant gender differences (women: 7, men: 13.5). The AE-QoL total score was 45.5, with significant gender differences in most domains. Strong correlations were found between AE-QoL scores and both AAS and AECT, highlighting the impact of both disease activity and control on QoL. Conclusions: The Latvian adaptation of the AAS, AECT, and AE-QoL questionnaires effectively assesses AE activity, control, and disease-related QoL. Our study reveals poor disease control, underscoring the need for tailored interventions and regular PROM evaluations, with the Latvian version of the AE-QoL questionnaire identifying five distinct domains compared to four in the original version.
Dyspnea Management in Patients Presenting to the Emergency Department at Cantonal Hospital Baselland—A Retrospective Observational Study and Medical Audit
Authors: Debernardi Emanuele , Jaun Fabienne , Boesing Maria , Leuppi Joerg Daniel , Lüthi-Corridori Giorgia
Published: February 2025

Background/Objectives: Dyspnea, the subjective experience of breathing discomfort, accounts for approximately 5% of emergency department (ED) presentations, 10% of general ward admissions, and 20% of intensive care unit (ICU) admissions. Despite its prevalence, dyspnea remains a challenging clinical manifestation for physicians. To the best of our knowledge, there are no international guidelines for the assessment and management of patients with dyspnea coming to the ED. In this study, we aim to evaluate how dyspnea cases are assessed and managed at Cantonal Hospital Baselland in Liestal (KSBL) and to audit these practices. Methods: We conducted a retrospective, observational study of hospital records from KSBL, including all patients presenting to the ED with dyspnea as their primary symptom who were subsequently admitted to the internal medicine ward for at least one night between January and December 2022. Data on assessment and management practices were compared using the medStandards algorithm. Results: A total of 823 cases were included. The median age at admission was 76 years (with a range of 15–99), and 57% of the patients were male. Blood pressure and heart rate were documented in 93.8% of the cases, respiratory rate in 61.4%, oxygen saturation in 96.1%, and body temperature in 86.3%. The patient’s subjective dyspnea description was recorded in 14.8% of the cases, while the temporal onset (timing of symptoms) was documented in 98.8%, and the intensity of effort triggering dyspnea was noted in 36.2% of cases. A dyspnea index scale was used in 7.8% and smoking status was documented in 41.1% of the cases. Lung percussion was performed in 2.6% of the cases, while a lung auscultation was performed in 94.4% and a heart auscultation was performed in 85.3% of cases. A complete blood count with a basic metabolic panel and TSH test was collected in 86.9% of the cases, while a blood gas analysis was collected in 34.0% of the cases. An ECG was reported in 87.5% of the cases. From the 337 patients who should have received an emergency ultrasound, 10.1% received one. The three most frequent final diagnoses were decompensated heart failure (28.4%), pneumonia (26.4%), and COVID-19 (17.0%). None of the three patients with a known neuromuscular disease were admitted to the shock room. Conclusions: Our findings reveal that the medStandards algorithm was only partially followed at the ED in KSBL Liestal, highlighting gaps in detailed history taking, respiratory rate measurement, lung percussion, and emergency ultrasound use. Given the frequency of dyspnea-related presentations, systematic improvements in the adherence to assessment protocols are urgently needed to enhance patient outcomes.

Published: February 2025

The ANB angle, the cephalometric parameter of choice for assessing the anteroposterior relationship between the maxilla and mandible, is subject to several limitations, prompting the investigation of alternative parameters. Objective: This study aimed to investigate the ABwise measurement as an alternative to the ANB angle for evaluating maxillomandibular relationships in orthodontics, particularly addressing the impact of skeletal discrepancies on conventional methods. Methods: A retrospective analysis was performed on a CBCT dataset of patients attending the University of Milan’s Department of Orthodontics and Maxillofacial Surgery, selected based on high-quality imaging, a full-cranium field of view, and a slice thickness between 150 and 300 μm. Eight craniofacial landmarks were annotated using the 3D Slicer software to calculate the ANB values and the new ABwise measurement. Statistical analyses included Spearman’s correlation (ρ), linear regression, and inter-rater agreement (Cohen’s κ score), with data classified into skeletal Classes I, II, and III based on defined thresholds. Results: 354 CBCT were selected and analyzed (mean age: 18.6 years). ABwise showed a strong correlation with the ANB angle (ρ = 0.805) and new normative ranges for ABwise were established: Class I (−1.4 ± 2.3 mm), Class II (>0.9 mm), and Class III (<−3.7 mm). Moderate agreement was observed between the ABwise and ANB classifications (κ = 0.527). ABwise effectively addressed limitations associated with divergence and vertical discrepancies, providing a more reliable assessment of skeletal sagittal relationships. Conclusions: ABwise presents a viable alternative to the ANB angle for three-dimensional cephalometric analysis, offering improved accuracy and alignment with radioprotection principles by reducing the CBCT field of view needed for its measurement. Further research is required in order to validate these findings across diverse populations and clinical scenarios.

Published: February 2025

Endometrial cancer (EC) is the most common gynecologic malignancy in developed countries, with rising incidence due to aging populations and obesity-related factors. This review explores the evolving molecular and FIGO classifications of EC, highlighting their significance in diagnosis, prognosis, and personalized treatment strategies. Molecular subtyping based on The Cancer Genome Atlas (TCGA) classification offers a more precise understanding of EC, dividing it into POLE ultramutated, microsatellite instability-high (MSI-H), copy-number low (CNL), and copy-number high (CNH) subtypes. Each subgroup has distinct genetic, histological, and prognostic characteristics. Recent updates to the FIGO staging system incorporate molecular features, allowing for more tailored treatment approaches. Advances in immunotherapy, targeted therapies, and novel therapeutic combinations have reshaped clinical management. This review emphasizes the integration of molecular diagnostics into routine practice, outlining challenges and future perspectives in managing EC for improved patient outcomes.

Authors: Piruta Joanna , Kułak Wojciech
Published: February 2025

Background: Musculoskeletal disorders associated with excessive smartphone use represent a significant health issue. Text neck syndrome is one such disorder within that group, increasingly affecting individuals worldwide across various age groups. The phenomenon of text neck may occur in individuals who frequently and for prolonged periods adopt a forward-flexed neck and head position while looking at the screens of mobile electronic devices. Various therapeutic methods are used in the treatment of text neck syndrome. However, there is no consensus on text neck rehabilitation, which poses a challenge for physiotherapists. Objective: The aim of this study is to analyze the phenomenon of text neck, with a particular emphasis on current scientific reports regarding the rehabilitation of text neck syndrome. The scoping review was conducted to determine the physiotherapy methods currently used in the treatment of individuals with text neck, assess their impact on symptom reduction, and identify existing knowledge gaps and limitations in the current literature on the rehabilitation of text neck syndrome. Design: A scoping review was conducted on the treatment of text neck syndrome based on electronic databases: PubMed, ResearchGate, Physiotherapy Evidence Database (PEDro), and the Cochrane Library. The databases were searched up to 1 December 2024. The inclusion criteria comprised studies investigating physiotherapy interventions for individuals with text neck, published between 2018 and 2024 and written in English. Results: A total of fifteen papers were reviewed, focusing on various methods used in text neck rehabilitation, including postural correction exercises, stabilization exercises, strengthening and stretching exercises, Pilates, PNF (Proprioceptive Neuromuscular Facilitation), kinesiology taping, Bowen therapy, and manual therapy. Nearly all studies were conducted in the adult population (93%), with the majority of studies taking place in India (60%). Conclusions: In summary, all studies suggest that appropriate physiotherapeutic interventions can provide significant benefits, including pain reduction, posture correction, and improved range of motion in the cervical spine. The best outcomes appear to be achieved by combining various therapeutic techniques. However, further high-quality research is needed to strengthen the evidence and offer reliable recommendations for clinical practice. Additionally, there is limited research on physiotherapy for text neck in the pediatric population, presenting a potential area for future studies.

Published: February 2025

Introduction: Patients with orthopedic injuries often require cast immobilization therapy using casts. Driving with a cast on the right lower limb restricts many things. This study aimed to investigate the factors associated with driving capacity after orthopedic fixation of the right lower limb in healthy adult volunteers. This study’s hypothesis was that the orthopedic splint immobilization would have delayed reaction when in a driving simulation. Materials and Methods: We carried out an experimental study between 17 April 2023 and 19 May 2023. We set up the study in two phases: a driving simulation experiment without immobilization with a cast on the right lower limb and a driving simulation experiment with immobilization with a cast on the right lower limb. The data collected through the questionnaire were then analyzed in R version 4.2.2. Results: A total of 47 individuals participated in the study with a mean height of 167.68, of which 68.09% were females. Overall, 78.7% of the study participants could not drive after immobilization with a cast on the right lower limb. There was a significant difference between participants who could drive and those who could not drive by height (p = 0.04), age (p = 0.038), and body type (p = 0.046). Conclusions: Our study demonstrates that an individual’s height, age, and body type are associated with an individual’s driving ability after orthopedic immobilization of the right lower limb. Our findings suggest that regulations regarding the ability to drive after orthopedic immobilization of the right lower limb must be reconsidered.

Published: February 2025

This study presents a foam sandwich structure reinforced with carbon fiber columns (FSS-CFC), which exhibits strong mechanical and sound insulation properties. The FSS-CFC consists of two face-sheets and a polyvinyl chloride (PVC) core containing multiple CFC cylinders arranged in a periodic array. The sound transmission loss (STL) measured in acoustic tube experiments closely aligns with the finite element simulation results, validating the reliability of the present research. Through characteristic analyses, the study reveals the sound insulation mechanism of FSS-CFC, identifying three distinct sound insulation dips caused by the standing wave resonance of the core, column-driven same-direction bending vibrations, and column-constrained opposite-direction bending vibrations in the sheets. It is also demonstrated that the sound insulation performance of FSS-CFC is insensitive to hydrostatic pressure changes. Finally, the FSS-CFC is optimized by the genetic algorithm in MATLAB and COMSOL. The optimized FSS-CFC displays good improvements in both mechanical and acoustic performance compared to the initial structure. The average STL in the frequency of 500 Hz to 25,000 Hz has increased by 3 dB, representing an improvement of approximately 25%. The sound insulation mechanism in FSS-CFC could provide valuable insights for the development of a pressure-resistant acoustic structure for use on deep-water vehicles.

Published: February 2025

To enable early identification of failure risks in ship systems and equipment, a dynamic cloud center of gravity model is developed for real-time system-level health assessment. First, the Functional Analysis System Technique (FAST) was applied to decompose the operational functions and dependencies of the intelligent machinery room system, enabling the structured establishment of a hierarchical evaluation index system. The comprehensive weight is derived through synergistic application of the fuzzy set (FS) theory and entropy weight. This process integrated expert-defined functional boundaries with measurable parameters critical to system performance. Then, an improved cloud center of gravity method based on the Gaussian cloud model and sliding time window method is used for the system’s adaptive health value calculation. The dynamic health model can achieve continuous online assessment and track the further evolution of the system. Finally, the proposed model is applied to the Fuel Oil Supply System (FOSS). The integration of system performance output and disassembly inspection results demonstrates that the method proposed in the article more accurately reflects the true health status changes in the system when mapping health values.

Authors: Sun Jingyu , Yi Zhimin , Zhuang Ziyi , Jiang Shengming
Published: February 2025

The automatic identification system (AIS) is an essential tool for modern ships, enabling the broadcast of identification and location information. However, the current AIS standard lacks security features, meaning that messages exchanged via AISs are transmitted in plaintext, which leads to security issues such as privacy leakage. Most existing solutions rely on public key cryptography. This paper proposes a physical-layer key generation protocol based on the current AIS standard (ITU-R M.1371-5). In the case of unicast AIS communication, the protocol utilizes channel randomness to generate symmetric keys for securing communications. Compared to public key cryptography, the proposed protocol offers advantages such as low overhead, elimination of third parties, and ease of implementation. Finally, this paper discusses the security of the protocol against various threats as well as evaluates its performance and overhead. Under common speed and signal-to-noise ratio (SNR) conditions, The protocol generates Advanced Encryption Standard (AES) keys of different lengths in under 4000 ms, and these keys successfully pass the National Institute of Standards and Technology (NIST) randomness test.

Published: February 2025

This study empirically examines the wealth effects of mergers and acquisitions (M&As) in the Indian capital market, focusing on cross-border M&As. This study considers a sample of 58 cross-border and 34 domestic M&As, comprising more than 50 percent of the shares acquired by the acquiring companies from 2004 to 2019. We analyzed the wealth effects of cross-border M&As by applying the event study methodology. The abnormal returns of domestic and cross-border mergers and acquisitions for various window periods were compared using an independent t-test. The wealth effects of the acquiring firm have been further investigated with the inclusion of top advisor services and without the inclusion of advisor services in mergers and acquisitions transactions. This result suggests that cross-border M&As do not create a significant positive return for shareholders. There is no considerable wealth gain for shareholders of acquiring companies in domestic and cross-border mergers and acquisitions. We also find that including top advisor services in the M&A process does not influence the acquiring firm’s wealth. The price-to-book value ratio of the acquiring firm is a significant determinant of its returns.

Published: February 2025

Territorial Space (TS) is characterized by its multifunctionality. The identification and management of Territorial Spatial Functions (TSFs) across multi-scale is crucial for achieving the SDGs. However, previous studies have primarily concentrated on the variations in TSFs within the administrative or grid units at a single scale, with multi-scale investigations remaining a challenge. This study focuses on the typical karst region of Guangxi province in China and develops a Multi-Scale Fusion model (MSF) for assessing TSFs and employs a coupling coordination degree (CCD) model to examine the TSFs relationships. Furthermore, principal component analysis (PCA) is used to classify various types of influencing factors, and the Revealed Comparative Advantage (RCA) index is employed to identify the primary types of influencing factors at the county level. The study integrates coupling coordination types and advantage factors into the zoning process. The results demonstrate: (1) Ecological function is the dominant function. At the administrative unit scale, production and living functions exhibit a spatial pattern of “high in the southeast and low in the northwest”, while ecological function shows the opposite pattern. Under grid units scale and multi-scale fusion, the high and low texture characteristics of production and ecological functions are more pronounced. (2) TSFs are primarily characterized by slight and moderate disorder. Slight disorder is widely distributed, while moderate disorder is predominantly found in the northwest karst mountainous regions. In contrast, coordinated relationships are more frequently observed in urban areas. (3) The driver types of TSFs can be categorized into four categories: Terrain-Population, Agriculture Development, Location-Economy, and Non-Agriculture Development. By integrating the TSFs relationships, six zones are delineated. Based on this, precise and differentiated optimization suggestions are proposed to promote orderly utilization and sustainable development of TS.

Published: February 2025

The preservation and management of riparian zones in nature protection areas are challenging due to the simultaneous demands of nature protection regulations, active nature tourism burdens, and local community needs. The local community’s willingness to participate in riparian zone management is an essential contribution to establishing successful long-term riparian zone management. This study aimed to gain insight into the perceptions of the local community, particularly landowners, on the management perspectives of riparian zones in nature protection areas. We used a questionnaire survey to gather data from three distinct localities within the North Vidzeme Biosphere Reserve (NVBR). In total, 734 respondents were interviewed, of which 40% were landowners who owned land in riparian zones. Landowners did not differ significantly from those without property rights in their willingness to undertake voluntary work to improve the quality of riparian zones. Landowners more often use riparian zones for cultural and recreational activities. Overall, the landowners had similar perceptions of riparian zone management to respondents without property rights in the NVBR.

Published: February 2025

Remote sensing observations have shown an increasing trend in the vegetation leaf area index (LAI) over the past three decades, with climate change and human activities identified as the primary drivers of vegetation change. However, a challenge remains in identifying and quantifying the role of different drivers. In this study, we employed the paired land use experiment (PLUE) approach, which is based on the concept of natural comparative controlled experiments, to assess the impacts of human activities, especially land management, in the Emin River Basin within the border between China and Kazakhstan. The comparable climate, alongside the significant differences in human activities between the two sides of the Emin River, makes it ideal for applying the PLUE method. We found that during 2001 to 2022, both regions experienced similar inter-annual trends. The leaf area index (LAI) increased in both regions (Chinese region: 8.3 × 10−3 yr−1m2m−2; Kazakhstan region: 5.8 × 10−4 yr−1m2m−2), with the most significant increase observed in the Chinese cropland region (2.79 × 10−2 yr−1m2m−2). Through residual trend analysis, we found that the increase in the LAI from April to May in the Kazakhstan region was mainly positively influenced by human grazing activities. Comparatively, the LAI growth from June to August in the Chinese cropland region was mainly attributed to land managements. This study emphasizes the influence of human activities, especially land management, on vegetation and reveals the key factors affecting the LAI within different periods.

This study explores the transformation of the ethno-linguistic identity of Kazakhstani student youth within the multilingual context of Kazakhstan, considering the impact of the country’s language policies. Our research analyzes language choices, focusing on the knowledge and factors influencing parents and Kazakhstani youth when making decisions about children’s language education, as well as the strategies they adopt for language use. The empirical basis of this study is a sociolinguistic survey conducted among 823 Kazakhstani university students aged 18 to 30 from various regions of the country in 2023. Data were collected through questionnaires and interviews, which were subjected to both qualitative and quantitative analysis. The findings were supplemented by the results of the most recent national census. This comparative analysis provides a comprehensive understanding of the current state and emerging trends in the ethno-linguistic identity of Kazakhstani youth and the broader linguistic landscape of the country. The results indicate that large-scale state initiatives aimed at reinforcing the status of the Kazakh language have had a positive impact on its recognition. However, the data also reveal persistent fluctuations in ethno-linguistic identity, which can be attributed to various extralinguistic factors. This study highlights the role of both educational and family language policies as key drivers in shaping ethno-linguistic identity.

The genus Camphora encompasses species of significant ecological and economic importance, such as C. parthenoxylon and C. officinarum, which exhibit distinct phenotypic traits and stress responses. This study seeks to elucidate the molecular basis of cold tolerance through comparative transcriptomic analysis complemented by physiological characterization. RNA sequencing revealed 6123 differentially expressed genes between the two species, with enriched pathways related to cold stress, oxidative stress, carotenoid biosynthesis, and photosynthesis. Key genes, such as annexin D5, chlorophyll a/b-binding protein, early light-induced protein 1, 9-cis-epoxycarotenoid dioxygenase, were identified as critical regulators of frost resistance, photosynthetic efficiency, and carotenoid biosynthesis. Functional enrichment analyses highlighted the involvement of signal transduction, membrane stabilization, and secondary metabolism in adaptive responses. Physiological assays supported these findings, showing higher chlorophyll and carotenoid content and enhanced antioxidative enzyme activities in C. parthenoxylon. These results provide valuable insights into the genetic and biochemical mechanisms underlying stress adaptation in Camphora species and offer promising targets for enhancing resilience in economically valuable plants.

Living kidney transplantation yields better outcomes for recipients than deceased donation, though it may present long-term challenges for donors. This study assessed the quality of life (QoL) of living kidney donors in Greece using the SF-36 questionnaire and examined associated sociodemographic and clinical factors. This cross-sectional study included 242 clinically stable kidney donors from Laiko General Hospital’s Kidney Donor Outpatient Clinic in Athens. Data on demographics, comorbidities, laboratory parameters, and QoL were collected. Spearman’s correlation coefficients were used to identify associations between QoL scores and influencing factors. The majority of donors were female (73.55%). Donors reported high QoL, with median PCS and MCS scores of 55.27 (49.08–57.73) and 54.17 (46.64–59.93), respectively. Male donors had higher PCS and MCS scores than females (p = 0.028 and p = 0.004). Laparoscopic nephrectomy was associated with better mental health and physical outcomes compared to open surgery (p < 0.001). Higher education and eGFR correlated with better PCS scores, while older age negatively affected QoL (p < 0.05). Living kidney donors reported a satisfactory level of overall QoL post-donation. Lower QoL scores were correlated with the female gender, older age, and open nephrectomy. These findings may further reinforce support for our current organ donation policy. Non-modifiable factors appear to influence donor quality of life. These findings reinforce the current organ donation policy while emphasizing the need for careful pre-transplant counseling and ongoing monitoring post-donation.

Published: February 2025

This study investigated the use of activated biochar derived from olive stone waste and recycled masonry aggregates in porous mortar mixtures and assessed their behaviour under accelerated carbonation curing conditions. Three mortar mixtures were produced, incorporating 0%, 5%, and 10% activated biochar by volume. The physical, chemical, and mechanical properties of the mortars were analysed, including the compressive strength, flexural strength, water absorption, porosity, and CO2 capture capacity. Additionally, calorimetry tests were performed on cement pastes with 0%, 0.5%, 1%, 3%, 15%, and 20% activated biochar to evaluate their impact on setting times and ensure compatibility between activated biochar and cement. The results showed that the addition of biochar improved mechanical properties, particularly under accelerated carbonation curing, whereas active biochar (AcB) significantly enhanced the compressive and flexural strengths. Furthermore, biochar incorporation boosted CO2 capture efficiency, with the 10% biochar mix showing up to 147% higher CO2 uptake, compared with a control. These findings suggest that activated biochar and recycled masonry aggregates can be effectively utilised to develop sustainable construction materials and thereby contribute to carbon sequestration and the reduction in environmental impacts. This research fills the gaps in the current knowledge on the use of activated biochar from olive stones waste in cement-base materials under accelerated carbonation conditions.
Reflexivity and Duplicability in Set Theory
Authors: Manca Vincenzo
Published: February 2025

Set reflexivity and duplicability are considered by showing, with different proofs, their equivalence with Dedekind’s infinity. Then, an easy derivation of the Schröder–Bernstein theorem is presented, a fundamental result in the theory of cardinal numbers, usually based on arguments that are not very intuitive.
Multilayer Neurolearning of Measurement-Information-Poor Hydraulic Robotic Manipulators with Disturbance Compensation
Authors: Yang Guichao , Shi Zhiying
Published: February 2025

In order to further improve the tracking performance of multiple-degree-of-freedom serial electro-hydraulic robotic manipulators, a high-performance multilayer neurocontroller will be proposed. In detail, multilayer neural networks will be employed to approximate the smooth and non-smooth state-dependent modeling uncertainties. Meanwhile, extended state observers will be utilized to estimate matched and unmatched time-varying disturbances. Moreover, these estimated values will be incorporated into the synthesized controller to compensate for the modeling uncertainties. Significantly, the proposed controller without “explosion of complexity” is suitable for the scene where the joint angular velocities are not measurable. Additionally, the sensor measurement noises can be reduced and input saturation nonlinearity will be handled.

Published: February 2025

As the proportion of renewable energy sources integrated into the power grid increases, it imposes significant volatility on the grid, leading to uneven load distribution across certain transmission lines. Rotating Power Flow Controllers (RPFCs) based on Rotating Phase-Shifting Transformers (RPSTs) offer a viable solution to such issues in lines rated at 10 kV and below. This paper begins with a brief introduction to RPFCs, followed by the modeling of their topology for a single-circuit line and the derivation of active and reactive power flow formulas. Notably, this paper introduces intelligent optimization algorithms to this field for the first time, employing an improved hybrid particle swarm optimization (HPSO) algorithm to control the active power while keeping the reactive power constant and subsequently adjusting the reactive power while maintaining the active power steady, thereby achieving power regulation. Using Matlab/Simulink simulations, this strategy was compared with adaptive adjustment strategies, verifying that it exhibits reduced power fluctuations and overshoots during the adjustment process, thus confirming the effectiveness of the adjustment scheme. By leveraging this algorithm in conjunction with simulations, a Q-P operating range diagram for transmission lines was plotted, determining the adjustable range of actual power.
