Introduction: NTRK-rearranged spindle cell neoplasm is an emerging tumor entity. The genetic mechanisms and prognostic implications of this entity are mainly unknown. The corresponding targeting therapy strategies have been widely developed. Method: In this study, we summarized the immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) characteristics. Also, we have explored the genetic mechanisms and prognostic implications of this entity. Results: We identified two NTRK1-associated gene sub types by consensus clustering. Besides, we established an NTRK1-associated gene prognostic model that predicted the survival of Sarcoma (SARC) based on the TCGA dataset. Two NTRK1-associated genes are related to the prediction of clinical outcomes. Discussion/Conclusion: A new classification system of SARC based on NTRK1-associated gene signatures has been established.

Cognitive Radio Networks (CRNs) represent a cutting-edge solution to the growing problem of limited available spectrum. With the increasing demand for wireless communication services, the efficient utilization of spectrum resources becomes paramount. Green CRNs offer a dynamic and opportunistic approach by intelligently sensing and accessing idle licensed spectrum, known as white spaces focusing on environmentally conscious communication methods. These unoccupied frequency bands, left unused by primary users (PUs), present an opportunity for CRNs to enhance spectrum utilization and alleviate the spectrum scarcity challenge. In the presented study, we concentrate on energy conservation in “Green” CRNs, with a specific focus on base stations (BSs). We suggest an energy-efficient approach that utilizes multiple sleep modes employing an N-policy, with the objective of addressing the growing need for environmentally friendly communication practices. To model the energy-saving process and assess system performance, we employ a semi-Markov process (SMP). Moreover, the paper provides a detailed analysis of performance metrics, encompassing average latency for Secondary Users (SUs), throughput of the system, energy saving factor, and energy consumption.

Accumulating data from several large, placebo-controlled studies suggests that sodium-glucose transporter 2 (SGLT-2) inhibitors and glucagon-like peptide 1 receptor (GLP-1) receptor agonists offer therapeutic benefits in the management of cardiovascular diseases, regardless of the patient’s diabetic status. In addition to their effects on glucose excretion, SGLT2 inhibitors have a positive impact on systemic metabolism. The aim of this study was to establish a non-invasive preclinical model of metabolic syndrome (MetS) to investigate the effects of novel antidiabetic therapies beyond glucose reduction, independent of obesity. Eighteen healthy adult Beagle dogs were fed an isocaloric Western diet (WD) for ten weeks. Biospecimens were collected at baseline (BAS1) and after ten weeks of WD feeding (BAS2) for measurement of blood pressure (BP), serum chemistry, lipoprotein profiling, fasting blood glucose, glucagon, insulin, NT-proBNP, BUN, creatinine, angiotensins, oxidative stress biomarkers, serum, urine and fecal metabolomics. Differences between BAS1 and BAS2 were analyzed using non-parametric Wilcoxon signed-rank testing with continuity correction. The isocaloric WD model induced significant variations in several markers of MetS, including elevated BP, increased glucose levels, and reduced HDL-cholesterol. It also caused an increase in circulating NT-proBNP levels, a decrease in serum bicarbonate levels, and significant changes in general metabolism, lipids, and biogenic amines. Short-term, isocaloric feeding with a WD in dogs replicates key biological features of MetS while also causing low-grade metabolic acidosis and elevating natriuretic peptides. These findings support the use of the WD canine model for studying the metabolic effects of new antidiabetic therapies independent of obesity.

Background. Controversial evidence suggests a potential association between female genital mutilation (FGM/C) and adverse obstetric outcomes, with type III FGM/C (infibulation) carrying the greatest risk. Objectives: To assess current rate of adverse obstetric outcomes in women with type III female genital mutilation and cutting (FGM/C; infibulation) delivering across different settings worldwide. Search Strategy. Two authors searched relevant literature in the PubMed, Scopus, Embase, and ClinicalTrials.gov databases from inception to Jan 1, 2023, looking for articles reporting outcomes of women with type III FGM/C compared with women with no FGM/C. Selection criteria. Studies were selected if they included the main outcome of postpartum haemorrhage (PPH) or secondary outcomes, which included major conditions affecting maternal-neonatal health during labour and delivery. Data Collection and Analysis: DerSimonian-Laird random effects meta-analysis was performed and pooled effect estimates with corresponding 95% confidence intervals were computed. Heterogeneity was assessed using the I 2 statistic. Meta regression for relevant covariates was performed when data on relevant confounders were available. The Newcastle-Ottawa scale (NOS) was used to assess quality of observational studies. The level of evidence was assessed with the GRADE method. Main Results: 14 observational studies including 15,320 type III FGM/C women and 59,347 controls were eligible. The risk for postpartum haemorrhage was significantly increased in type III FGM/C, in the main analysis (OR 1.83, 95% CI 1.03 to 3.24, I 2=93%), in pooling of data adjusted for confounders (aOR 1.76, CI 1.42 to 2.17, I 2= 0%), and in sensitivity analysis of higher quality studies with NOS≥7 (OR 2.76, CI 1.38 to 5.51, I 2= 95%). Meta-regression showed that nulliparity was significantly and positively associated with postpartum haemorrhage. Similarly, analysis of data adjusted for confounders showed an increased risk of episiotomy in type III FGM/C (aOR 1.56, CI 1.03 to 2.35, I 2= 52%). Sensitivity analysis of studies with NOS≥7 revealed a significant increase for episiotomy (OR 7.53, CI 1.19 to 47.54, I 2= 96%), perineal tears (OR 4.24, CI 1.09 to 16.46, I 2= 66%), prolonged second stage of labour (OR 5.19, 95% CI 1.00 to 26.85, I 2= 66%), and Apgar score less than 7 (OR 4.19, CI 1.64 to 10.70, I 2= 0%). No difference was found regarding obstetric anal sphincter injuries and mode of delivery in these women. Deinfibulation achieved similar obstetric and neonatal outcomes to women who never had type III FGM. The overall quality of the studies was adequate (median NOS score: 7; IQR: 6-8), the level of evidence, according to the GRADE assessment, was low. Conclusions. These results consistently show an increased risk of adverse obstetric outcomes in women with FGM/C type III. Infibulation substantially increases the risk for PPH, particularly in nulliparae.

Breast cancer is one of the most prevalent forms of cancer, affecting approximately 1 in 8 women during their lifetime. Deciding on breast cancer treatment, which includes the choice between surgical options, frequently demands prompt decision-making within an 8-week timeframe. However, many women lack the necessary knowledge and preparation for making informed decisions. Anxiety and unsatisfactory outcomes can result from inadequate decision-making processes, leading to decisional regret and revision surgeries. Shared decision-making and personalized decision aids have shown positive effects on patient satisfaction and treatment outcomes. We introduce Breamy, a prototype mobile health application that utilizes augmented reality (AR) technology to assist breast cancer patients in making more informed decisions. Breamy provides 3D visualizations of different surgical procedures, aiming to improve confidence in surgical decision-making, reduce decisional regret, and enhance patient well-being after surgery. To determine the perception of the usefulness of Breamy, we collected data from 166 participants through an online survey. The results suggest that Breamy has the potential to reduce patients’ anxiety levels and assist them in decision-making.

Land use change-induced, accelerated soil erosion is a main driver of soil organic carbon (SOC) loss. However, soil erosion and SOC loss are not linked linearly because SOC-rich topsoil is eroded at the initial stages of degradation while horizons with lower SOC content are eroded later, but often at higher rates. To assess the contribution of soil erosion to the changing global carbon cycle, it is essential to understand how SOC changes when soil erosion accelerates. On cropland, dynamic replacement of organic carbon (OC) limits the net loss of soil OC stocks and causes a small, but steady flux of C from the atmosphere to soil and onwards landscape sinks. Rangelands, on the other hand, may loose their entire OC pool as a result of soil erosion because soils loose their productivity quickly when affected by erosion, disabling the replacement of SOC. Most rangelands have experienced erosion and degradation during the 20 th century, i.e. at the same time when greenhouse gas emissions from burning fossil fuels also increased. Distinguishing the contributions of rangeland land use change from other sources is essential for understanding the human impact on the global carbon cycle and climate during the 20 th century. The use of small farm reservoirs has been widespread in the South African Karoo during the last century. Many reservoirs have silted up and thus potentially document the soil properties during the period of sediment accumulation. This study tests the potential to reconstruct 20 th century SOC and total nitrogen (TN) change in rangeland soils. Five reservoir sediment profiles were sampled and texture, total organic carbon (TOC), TN and 137Cs of the samples were analysed and compared along the reservoir profiles. The results show that with one exception the oldest sediments contain more TOC and TN than the older ones. This indicates a loss of SOC and TN early after the dams were constructed in the 1920s and 1930s. These distinct changes also illustrate that the small reservoir sediments have the potential to reconstruct the impact of land use, soil erosion and associated SOC change in rangelands.

INTRODUCTION: Inappropriate sinus tachycardia (IST) is a common condition with frequently not tolerated beta-blockers or ivabradine and a high rate of complication in ablation strategy; we describe an alternative anatomical approach of sinus node modulation. METHODOLOGY: This retrospective study describes a case series of 6 patients from two centers diagnosed with symptomatic IST undergoing sinus node ablation. RESULTS: The mean age was 40.6 ± 13.9 years; five of the six patients were female, 100% of patients reported heart palpitations, and 66% reported dizziness, the average HR on a 24-h Holter was 93.2 ±7.9 bpm. HR during the first stage of a stress test using a standard Bruce protocol was 150 ±70 bpm, The average HR on 24-hour Holter post-ablation was 75 ± 5.6 bpm, the sinus rate HR during stage 1 of a Bruce protocol exercise stress test was 120 ± 10 bpm. CONCLUSION: This is the first case series reporting the acute and long-term results of a novel anatomical approach for SNM to treat IST targeting the AR under ICE guidance, The novel anatomic ICE-guided catheter ablation approach aimed to identify the earliest activation at the AR with an extension of RF lesions towards its septal region seems effective and safe to modulate the SN in symptomatic patients with IST refractory to medical treatment.

Direct synthesis of layer-tunable and transfer-free graphene on technologically important substrates is highly valued for various electronics and device applications. Here, we report a novel synthesis approach combining ion implantation for a precise graphene layer control and dual-metal smart Janus substrate for a diffusion-limiting graphene formation, to directly synthesize layer-tunable graphene on arbitrary substrates without the post-synthesis layer transfer process. C ion implantation was performed on Cu-Ni film deposited on a variety of device-relevant substrates. Upon thermal annealing to promote Cu-Ni alloying, the pre-implanted C-atoms in the Ni layer are pushed towards the Ni/substrate interface by the top Cu layer due to the poor C-solubility in Cu. As a result, the expelled C-atoms precipitate into graphene structure at the interface facilitated by the Cu-like alloy catalysis. After removing the alloyed Cu-like surface layer, the layer-tunable graphene on the desired substrate is directly realized. ReaxFF was performed to elucidate the graphene formation mechanisms in this novel synthesis approach. Three ordinary devices using as-synthesized graphene were fabricated on Si, SiO2, and glass substrates to demonstrate the graphene quality of our layer-tunable and transfer-free synthesis approach and the excellent performance characteristics of these low-cost manufacturing devices: field-effect transistors, heating devices, and near-infrared photodetectors.

Introduction: Pulsed electric field (PEF) ablation relies on the intersection of a critical voltage gradient with tissue to cause cell death. Field-based lesion formation with PEF technologies may still depend on catheter-tissue contact (CTC). The purpose of this study was to assess the impact of CTC on PEF lesion formation with an investigational large area focal (LAF) catheter in a preclinical model. Methods: PEF ablation via a 10-spline LAF catheter was used to create discrete RV lesions and atrial lesion sets in 10 swine (8 acute, 2 chronic). Local impedance (LI) was used to assess CTC. Lesions were assigned to 3 cohorts using LI above baseline: No Tissue Contact (NTC: ≤∆10Ω, close proximity to tissue), Low Tissue Contact (LTC: ∆11-29Ω), and High Tissue Contact (HTC: ≥∆30Ω). Acute animals were infused with triphenyl tetrazolium chloride (TTC) and sacrificed ≥2hrs post-treatment. Chronic animals were remapped 30 days post-index procedure and stained with infused TTC. Results: Mean (±SD) RV treatment sizes between LTC (n=14) and HTC (n=17) lesions were not significantly different (depth: 5.65±1.96mm vs 5.68±2.05mm, p=0.999; width: 15.68±5.22mm vs 16.98±4.45mm, p=0.737) while mean treatment size for NTC lesions (n=6) was significantly smaller (1.67±1.16mm depth, 5.97±4.48mm width, p<0.05). For atrial lesion sets, acute and chronic conduction block were achieved with both LTC (N=7) and HTC (N=6), and NTC resulted in gaps. Conclusions: PEF ablation with a specialized LAF catheter in a swine model is dependent on CTC. LI as an indicator of CTC may aid in the creation of consistent transmural lesions in PEF ablation.

Purpose: Predicting Bronchopulmonary dysplasia (BPD) to assess the risk-benefit of the therapy is necessary due to the side effects of medications. We developed and validated an instrument for predicting BDP and compared it with an instrument currently used in neonates born in a Brazilian hospital. Methods: Retrospective cohort of patients born between 2016 and 2020, with gestational ages (GA) between 23 and 30 weeks. Predictive equations were elaborated using methods of selection of component variables: stepwise, conditional inference tree, Fisher’s exact test and all the collected variables; 70% of the sample was randomly selected for the construction of risk prediction equations, and the remaining 30% were used for their validation, application and comparison with the National Institute of Child Health and Human Development (NICHD) instrument published in 2011, currently used in that institution. Sensitivity, specificity, and predictive values of the equations were calculated. Results: The equation that used variables whose p-value was lower than 5% in Fisher’s exact test (clinical chorioamnionitis, GA, birth weight, sex, need for surfactant, patent ductus arteriosus, late-onset sepsis, inspired fraction of oxygen, and respiratory support) presented the best results: specificity of 98% and positive predictive value of 93%. Our instrument allowed applying the prediction to small-for-gestational-age (SGA). The currently used calculator applied to our population had a specificity of 93% and a positive predictive value of 75% and could not be applied to SGA patients. Conclusion: Our tool has a higher specificity and positive predictive value than the foreign instrument and is suited for SGA.

Pyroptosis is a type of programmed lytic cell death mechanism associated with the activation of inflammasomes and inflammatory caspases, proteolytic cleavage of gasdermin proteins (GSDMA-E and PJVK), resulting in the formation of pores in cellular membranes such as plasma membrane and mitochondrial membranes. Here, I show that GSDMC expression was increased, GSDME (DFNA5) and PJVK (DFNB59) expression were decreased in uterine corpus endometrial carcinoma (UCEC) cells compared to normal endometrial cells. Total percentage of patients affected by mutations in gasdermin family of genes was the highest in UCEC compared to other cancer types. The highest mutation percentage among the members of the protein family was observed for GSDME which also showed the most significant difference in the mRNA expression among other family members between tumor and normal samples, possibly pointing to its relatively higher importance in the pathogenesis of UCEC. Gasdermin family of genes (except GSDMA) had higher transcript levels in serous endometrial adenocarcinoma than in endometrioid endometrial adenocarcinoma, demonstrating the histotype-dependent expression of the most of gasdermin genes in UCEC. Transcript levels of certain gasdermin family members also differed based on residual tumor status and histologic tumor grade; however, the expression of any gasdermin genes did not change depending on menopause status. This study suggests that a better mechanistic understanding of pyroptotic cell death in uterine corpus endometrial carcinoma might help identify novel therapeutic targets for the management of this gynecological malignancy.

Objective: Describe antibiotic utilization pre- and post-widespread utilization of highly effective CFTR modulator therapy at a single pediatric CF center. Design: In October 2019, the United States Food and Drug Administration approved elexacaftor/tezacaftor/ivacaftor (ETI), a highly effective CFTR modulator therapy, for people with CF (pwCF). We performed a single-center, retrospective review of PO and IV antibiotics prescribed for pulmonary exacerbations (PEx) between 1/1/2017 and 12/31/2022. Results: Of the 193 pwCF included, 69 (36%) received a course of IV antibiotics in the pre-ETI period compared to 44 (23%) in the post-period. Oral antibiotic courses decreased from 174 (90%) to 141 (73%) individuals. The median combined IV and PO treatment courses per individual decreased from 3 to 2. The percent of individuals treated for resistant organisms including methicillin-resistant Staphylococcus aureus (46% to 32%) and Pseudomonas aeruginosa (40% to 28%) also decreased from the pre- and post-ETI period. Conclusions: This single center experience indicates a dramatic decrease in PO and IV antibiotics used to treat PEx among pwCF in the post-ETI period.

Hemorrhoids are the most common perianal disease, but current observational studies have yielded inconsistent results in investigating the etiology. Our further exploration of the etiology will help prevent the disease. We conducted a two-sample bidirectional Mendelian randomization (MR) analysis using publicly available genome-wide association studies (GWAS) statistics from multiple consortia. The inverse-variance weighted (IVW) method was used for the primary analysis. We applied four complementary methods, including weighted median, weighted mode, MR-Egger regression, and Cochrane’s Q value, to detect and correct the effects of horizontal pleiotropy. Genetically determined constipation (OR = 0.97, 95% CI: 0.91-1.03, P = 0.28) and diarrhea (OR = 1.00, 95% CI: 0.99-1.01, P = 0.90) did not have a causal effect on HEM but stool frequency (OR = 1.28, 95% CI: 1.05-1.55, P = 0.01), waist-to-hip ratio adjusted for BMI (OR = 1.11, 95% CI: 1.06-1.64, P = 1.59×10 -5), and order Burkholderiales (OR = 1.09, 95% CI = 1.04–1.14, p = 1.63×10 -4) had a causal effect on. Furthermore, we found a significant causal effect of constipation on HEM in the reverse MR analysis (OR = 1.21, 95% CI: 1.13-1.28, P = 3.72×10 -9). The results of MR-Egger regression, Weighted Median, and Weighted Mode methods were consistent with those of the IVW method. Horizontal pleiotropy was unlikely to distort the causal estimates, as indicated by the sensitivity analysis. Our MR analysis reveals a causal association between stool frequency and waist-to-hip ratio with HEM, despite variations in results reported by observational studies. Unexpectedly, we found a relationship between the order Burkholderiales in the gut flora and HEM, although the mechanism is unclear.

MultipleCutaneousMyxofibrosarcoma on the Right Arm：Clinicopathological Features andDifferential Diagnosis

Bicuspid aortic valve is the most common congenital heart defect. Transthoracic echocardiogram is the initial tool to assess and diagnose this condition, however, transesophageal echocardiogram with 3D modalities, including transillumination have a better anatomical and functional evaluation of the valve, allowing to classify the bicuspid aortic valve according to the position of the raphe and assess the main vessels for complications or exclude other cardiovascular diseases.

Most scientist agree that subjective tinnitus is the pathological result of an interaction of damage to the peripheral auditory system and central neuroplastic adaptations. Here we investigate such tinnitus related adaptations in the primary auditory cortex (AC) 13 days after noise trauma induction of tinnitus by quantifying the density of the extracellular matrix (ECM) in the AC of Mongolian gerbils (Meriones unguiculatus). The ECM density has been shown to be relevant for neuroplastic processes and synaptic stability within the cortex. We utilized a mild monaural acoustic noise trauma in 9 gerbils to induce tinnitus and a sham exposure in 3 control animals. Tinnitus was assessed by a behavioral response paradigm. Four of the trauma animals did show tinnitus 13 days after trauma (T), the remaining 5 trauma (NT) and the 3 control animals (C) did not show the percept. The ECM density 13 days after trauma was quantified using immunofluorescence luminance of Wisteria floribunda lectin-fluoresceine-5-isothiocyanate (WFA-FITC) on histological slices of the primary AC, relative to the non-auditory brainstem as a reference area. We found that the WFA-FITC luminance of the AC of NT animals was not significantly different from that of C animals. However, we found a significant increase of luminance in T animals’ ACs compared to NT or C animals’ cortices. This effect was found exclusively on the AC side contralateral to the trauma ear. These results point to a process of stabilization of synaptic connections in primary AC, which may be involved in the chronic manifestation of tinnitus.

Background: Systemic immune-inflammation index (SII) is currently considered as a potential new inflammatory marker, but its association with internal carotid artery (ICA) stenosis has been poorly studied. Therefore, the purpose of this study was to investigate whether there is a correlation between SII and the risk of stroke in patients with ICA stenosis or occlusion. Methods: A total of 302 participants (180 patients were symptomatic and 122 were asymptomatic) were enrolled in this study. Multivariate logistic regression analysis was used to determine independent risk factors for symptoms in patients with ICA stenosis. Additional subgroup analyses were performed according to degree of ICA stenosis. Results: Multivariate regression analysis showed SII (OR=1.001, 95%CI: 1.000-1.002, P=0.035) and ICA stenosis (OR=1.993, 95%CI: 1.436-2.767, P<0.001) were independently associated with symptoms in patients with ICA stenosis. Further analysis was performed using the SII quartile, with the first quartile as the reference, and the highest quartile SII level was significantly associated with symptomatic ICA (P=0.022). Trend test (P=0.004) showed a dose-response relationship between SII and the risk of symptoms in patients with ICA stenosis. In the stenosis degree analysis subgroup, SII was independently associated with symptoms in patients with severe stenosis and occlusion, while no correlation was observed in patients with moderate stenosis. Conclusions: Elevated SII levels were independently associated with symptoms in patients with ICA stenosis. Our findings suggest that SII may serve as a potential biomarker for symptomatic development in patients with severe ICA stenosis or occlusion.

Background Approximately 70 % of individuals allergic to birch pollen (Bet v 1.01 [Bet]) develop a secondary food allergy (e.g. hazelnut: Cor a 1.04 [Cor]), due to allergen cross-reactivity. However, standard immunotherapy for type I allergies often does not improve the food allergy sufficiently. We analyzed the allergen-specific and cross-reactive suppressive capacity of primary human regulatory T cells (Treg) induced by autologous IL-10-modulated dendritic cells (IL-10 DC) in vitro and in vivo. Methods CD4 + T cells of patients with birch pollen and associated hazelnut allergies were differentiated into Bet-specific or non-specific induced Treg (iTreg). After Bet- or Cor- specific restimulation the phenotype, proliferation and suppressive capacity of iTreg subsets were analyzed. iTreg function was further investigated in humanized mouse models of airway and intestinal allergy, generated by engraftment of peripheral blood mononuclear cells from allergic donors into immunodeficient animals. Results After IL-10 DC priming and allergen-specific restimulation (Bet or Cor) non-specific control iTreg remained anergic, whereas Bet-specific iTreg proliferated extensively and exhibited a regulatory phenotype (enhanced expression of CTLA-4, PD-1, TNFR2, IL-10). Accordingly, activated Bet-specific iTreg displayed a high capacity to suppress Bet- and Cor-induced responder T H2 cell responses in vitro, indicating induction of both allergen-specific (birch) and cross-reactive tolerance (hazelnut). In vivo, the beneficial effect of Bet-specific iTreg was verified in humanized mouse models of allergic airway and intestinal inflammation, resulting in reduced allergen-induced clinical symptoms and immune responses. Conclusion Human IL-10 DC-induced iTreg facilitate allergen-specific and cross-reactive tolerance. Therefore, they are potential candidates for regulatory cell therapy in allergic and autoimmune diseases.

In recent years, deep learning has made significant advancements in the computer-aided diagnosis for potentially life-threatening pneumothorax, especially with the rise of public pneumothorax diagnosis competitions using thousands of manually annotated chest X-rays. This review demonstrates the quick evolution of deep learning in pneumothorax diagnosis, offering innovative approaches to enhance accuracy, mitigate bias, and advance medical image segmentation. These investigations leverage deep learning, particularly the U-Net architecture with various backbones like ResNet34, achieving notable Dice coefficients up to 0.8574. They also compare deep learning frameworks to human radiologists, revealing similar diagnostic confidence. Innovative techniques like UNet++ improve segmentation accuracy by incorporating change maps and fusing outputs from different semantic levels. Notably, they emphasize AI pneumothorax detection enhancement through in-image annotations targeting the pleural separation, achieving an AUROC rating of 0.877 while mitigating bias from factors like thoracic tubes. This underscores the importance of high-quality in-image localization data for AI algorithm training. Additionally, Ens4B-UNet, a novel semantic segmentation model combining four U-Net architectures with pre-trained backbones, achieves a Dice similarity coefficient of 0.8608 on a challenging dataset. A two-stage deep learning approach secures the second position in a pneumothorax segmentation challenge, leveraging transfer learning and model architecture redesign (PTXNet) for a significant Dice coefficient boost of 18.76%. The Kim-Monte Carlo methodology employs small artificial neural networks for precise pneumothorax localization, outperforming conventional CNNs. Finally, an end-to-end deep learning framework featuring a fully convolutional DenseNet demonstrates competitive segmentation and diagnostic performance.

Objective: To investigate self-stigma’s influence on schizophrenia patients’ quality of life and its mediated impact by various factors. Methods: This study adopted a cross-sectional design and randomly selected 170 hospitalized patients with schizophrenia for evaluation. The assessment tools included the Positive and Negative Syndrome Scale (PANSS), Self-Esteem Inventory (SEI), Connor-Davidson Resilience Scale (CD-RISC), Internalized Stigma of Mental Illness Scale (ISMI), Schizophrenia Quality of Life Scale (SQLS), Coping Questionnaire for Schizophrenia Patients (CQSP), and Social Support Rating Scale (SSRS). Correlation analysis, regression analysis, and mediation analysis were used to test the correlation and mediation effects. Results: Self-stigma had a significant impact on quality of life (T = 8.13, p = 0.00). Self-esteem (T = -2.11, p = 0.04) and coping strategies, specifically problem-solving (T = -2.58, p = 0.01) and avoidance (T = 4.65, p = 0.00), have a greater impact on self-stigma. When self-stigma is used as a mediator, the problem-solving factor in coping strategies has an indirect effect on quality of life, which is significant (AB = -0.16, P = 0.02), while the avoidance factor in coping strategies has a direct effect on quality of life, which is significant (C’ = 0.54, p < 0.001), and an indirect effect, which is also significant (AB = 0.25, p < 0.001). Conclusion: Self-stigma has a significant impact on quality of life. Clinical work to improve the quality of life of patients with schizophrenia should focus on self-stigma and factors that affect self-stigma, especially self-esteem and coping strategies.

Over the last few decades, the agricultural industry has witnessed significant advancements in autonomous systems, primarily aimed at improving efficiency while reducing environmental impact. The critical role of complete coverage path planning cannot be overstated in this context. It involves determining an optimal path for tasks such as harvesting, mowing, and spraying, taking into account various factors like land topography, operational requirements, and robot characteristics. Our previous approach introduced a tree-based exploration method to generate potential solutions, coupled with an optimization process to select the best ones, considering field complexities and robot characteristics. Yet, despite its strengths, it had certain limitations, notably in computational time and number of examined driving directions. In this paper, we present a novel hybrid method that combines the comprehensive coverage benefits of our original approach with the computational efficiency of the Fields2Cover algorithm. Besides combining our previous approach and Fieds2Cover strengths for optimizing coverage area, overlaps, non-working path length and overall travel time, it significantly improves the computation process, enhances the flexibility of trajectory generation. It also takes into account the working trajectory inclinations for more advanced optimization to address soil erosion and energy consumption. In an effort to support this innovative approach, we have also created and made available a public dataset. This dataset includes both 2D and 3D representations of thirty agricultural fields located in France. This resource not only illustrates the effectiveness of our approach but also provides an invaluable data for future research in complete coverage path planning within the context of modern agriculture.

Aiming at the problem of weak yawing controllability of solar-powered Unmanned Aerial Vehicles (UAVs) with low-speed and high aspect-ratio Blended Wing Body (BWB) configuration, based on the large-scale aerodynamic characteristics of the biomimetic swallow tail, the influence of different opening methods and angles of the swallow tail on the aerodynamic characteristics and stability and controllability of an UAV was derived. The mechanism of the higher yawing control efficiency of the differential throttle compared to the conventional rudder is analyzed in order to significantly decrease the control efficiency at small throttle. We innovatively propose a yawing control method combining the opening of the swallow tail to a moderately separation state of local airflow and we validate it for the case of the landing control of a solar-powered UAV. The flight dynamics mode characteristics show that this control method has little impact on the lateral-directional stability of the UAV and that the control efficiency can be reserved to the same level of cruise state. Therefore, the control law of cruise state can be applied to landing state with swallow tail open directly, which enhances the lateral-directional control ability of the UAVs in a simple but efficiently way. Flight simulation and flight test results show that the proposed bionic control method of the swallow tail combined with differential throttle can effectively enhance the landing control ability of the UAVs, improve the response speed, and reduce the trajectory error.
