Published: March 2024

Abstract
Feature matching is an essential part in areas such as target tracking, and three-dimensional reconstruction. In case of rotational motion in the image, the rotating exercise core 8 statistical motion support volume is applied, resulting in low matching accuracy and long time to eliminate mismatching. A principal component analysis method is proposed to calculate rotation angle, feature points are changed in the grid and its neighborhood grid, which sets Gaussian threshold according to Euclid distance between neighborhood feature point and the matching feature point. And a new fractional statistical model is proposed to increase the number of correct matching pairs, So as to improve the fastness and accuracy of characteristic matching. Aiming at the problem of mismatch caused by local similarity of images, a data set is proposed to determine the data set by using geometric relationship between feature points, which analyzes the similarity between the data by the Person correlation coefficient, and sets the threshold to remove the feature matching pairs with low confidence, so as to improve the accuracy of feature matching. Experimental results show that the feature matching speed of the improved GMS algorithm is 3 times that of original GMS algorithm, and the false matching is eliminated in local similar region, which improves the quality of feature matching.

Abstract

Post-transplantation cyclophosphamide (PTCy) has been increasingly used to prevent graft-versus-host disease (GVHD). This prospective study aimed to assess the efficacy and safety of PTCy-based GVHD prophylaxis in allogeneic hematopoietic cell transplantation (HCT) for patients with higher-risk myelodysplastic syndrome (MDS) and compare post-transplantation outcomes between PTCy and anti-thymocyte globulin (ATG)-based regimen, as a historical control. The PTCy group (N = 152) showed a significantly lower incidence of grade II-IV acute GVHD (9.2 vs. 26.2%) and grade III-IV acute GVHD (2.6 vs. 15.9%) than the ATG group (N = 145), which was consistently observed across donor types. The incidence of moderate-to-severe chronic GVHD (22.7 vs. 23.1%), overall survival (2-years, 64.0 vs. 56.6%), and event-free survival (2-years, 52.6 vs. 51.7%) did not differ between the two groups. Neutrophil (15 vs. 11 d) and platelet engraftment times (25 vs. 15 d) were longer in the PTCy group. A trend towards lower non-relapse mortality (NRM, 2-years rate of 19.1 vs. 29.0%) and higher cumulative incidence of relapse (2-years rate of 27.8 vs. 17.2%) was observed in the PTCy group. In conclusion, allogeneic HCT using PTCy for higher-risk MDS demonstrated a significantly lower acute GVHD incidence with a favorable NRM and acceptable relapse rate.

Published: March 2024

Abstract

Gall wasps Leptocybe invasa and Ophelimus maskelli can cause loss of productivity by causing damage to Eucalyptus camaldulensis leaf tissues. Comparison of the biochemical compositions of noninfested and infested leaves may be useful to elucidate the roles of antioxidant defense compounds and antioxidant enzyme activities in protecting eucalyptus leaves against attack by insect pests. While glucose and fructose content increased in leaves infested by both gall wasps, proline content increased only in leaves infested by L. invasa. In flavonoid content, the reduction rate of 16.5% in leaves infested with L. invasa was 33.7% with O. maskelli. Total antioxidant capacity decreased with O. maskelli infestation but did not change with L. invasa infestation. Copper ion reduction capacity increased significantly with both pest infestations. Ascorbic acid increased by 87% in L. invasa infestation and 120% in O. maskelli infestation compared to control. The increase observed of superoxide dismutase activity in infested leaves was calculated as 29% for L. invasa and 20% for O. maskelli. O. maskelli infestation caused an increase in carotenoid content in non-infested leaves (total 7.29, Xan/Cds 5.0) but significantly decreased it in infested leaves (toplam 2.98, Xan/Cds 3.2). Superoxide generation rates of noninfested and infested leaves from the infested trees were found to be higher than those of the control samples. The biochemical composition of the infested and noninfested leaves of the infested plants also differs. The invasion of gall wasps triggers oxidative stress by increasing the rate of superoxide production in eucalyptus leaves.

Published: March 2024

Abstract

As a common defect type, rust defect of power components is one of the important hidden dangers that harm the safe operation of transmission lines. How to quickly and accurately discover and repair the rusted power components is an urgent problem to be solved in power inspection. Aiming at the above problem, in this study, a Rust-Defect YOLO (RD-YOLO) is proposed to perform power components identification and rust defect detection in aerial images. Firstly, Coordinate Channel Attention and Residual Module (CCARM) is proposed to enhance multi-scale detection precision, which is applied to the backbone CSPDarknet-53 to suppress the influence of background noise and enhance features extraction capability of power components. Secondly, Receptive Field Block (RFB) and Efficient Convolutional Block Attention Module (ECBAM) are introduced to PANet to strengthen deep and shallow features fusion, which alleviate the information reduction or loss of small targets, and reduce the inconsistency of features between different levels. Finally, Contrast sample strategy and Focal loss function are adopted to train and optimize RD-YOLO, and experiments are executed on a self-bulit dataset. Experimental results show that the mAP of power components identification reaches 92.33%, which is improved 7.82% compared with the original YOLOX. More importantly, the AP of rust defect detection attains 95%, which is increased by 18%, 20%, 11%, 9% and 5% compared with those of Faster R-CNN, SSD, YOLOv5, YOLOX and YOLOv7. Comparative experimental results demonstrate that the proposed model achieves good performance in power components identification and rust defect detection, and is promising for the future automatic visual inspection of transmission lines.

Abstract

To study the effects of nano silicon (Si), mycorrhiza, and vermicompost on some physiological traits of triticale under salinity stress, a factorial experiment was conducted based on a randomized complete block design with three replications in 2021‒2022. Experimental factors included salinity at three levels [no-salt (control or S0), salinity 30 (S1), and 60 (S2) mM by NaCl equivalent to 1.71, 5.53, and 8.3 dS.m− 1, respectively], application of bio-organic fertilizers (no application (B0), application of vermicompost (B1), mycorrhiza (B2), and application both of vermicompost and mycorrhiza (B3)), and three nano Si levels (without nano Si as control (N0), application of 30 (N1), and 60 (N2) mg.L− 1). Means comparison revealed that under 60 mM salinity conditions, application of bio-organic fertilizers and 60 mg.L− 1 nano Si (B3N2) increased grain yield (29.62%), chlorophyll index (14.57, 16.78, and 20.38%), relative water content (12.39, 12.01, and 14.57%), and quantum yield (4.54, 6.6, and 14.62%) at booting, heading, and grain filling stages, respectively, in comparison with no application of these fertilizers and nano Si (B0N0) under severe salinity stress at the same stages as S2. However, under severe salinity stress, the application of bio-organic fertilizers and nano Si as B3N2 decreased electrical conductivity (14.71, 10.45, and 13.52%) at the booting, heading, and grain filling stages, respectively, as well as hydrogen peroxide and malondialdehyde content (43.94 and 49.71%, respectively) in comparison with S2B0N0. Based on the results, both mycorrhiza with vermicompost and foliar application of 60 mg.L− 1 nano Si under 60 mM salinity conditions could increase the activities of catalase (69.52%), peroxidase (67%), and polyphenol oxidase (69.52%) enzymes, proline (75.75%), soluble sugar content (55.63%), and anthocyanin content (64.28%) compared to no application of bio-organic fertilizers and nano Si under no salinity level. Overall, the application of bio-organic fertilizers and nano Si was beneficial for improving triticale plants' salinity resistance.

Published: March 2024

Abstract

In this paper, sulfur-doped carbon nanotubes were synthesized and modified at 600, 700 and 800°C. The results showed that the amount of sulfur doped in carbon nanotubes increased with the increase of temperature, which were 0.78%, 0.98%, and 1.07%, respectively, but the carbon/sulfur binding mode did not change. At the same time, sulfur doping significantly increased the specific surface area, which was conducive to improving the infiltration of the electrolyte into the electrode piece. Sulfur-doped carbon nanotubes are used as conductive agents for the cathode NCM523 of lithium-ion batteries, and compared with untreated carbon nanotubes, they effectively improve the battery polarization, reduce the internal resistance, and greatly improve the ratio performance, and in terms of cycling performance, the capacity retention rate of the battery is increased from 71.3% to 81 ~ 85%.

Abstract
Purposes: Many variables such as psychiatric training, experiences, institution, and region characteristics may affect approaches of psychiatrists to methamphetamine-associated psychotic disorder (MAP) treatment. This study was aimed to reach adult psychiatrists actively practicing in Turkey through an internet-based survey and to determine their practices and attitudes to MAP treatment.
Methods: This was an internet-based, double-blind, quantitative, cross-sectional, psychiatrist approach-based observational survey. Participants were divided into three groups based on their answers: Those who do not follow-up any MAP patient were group 1 (n=78), partially involved in the treatment process of at least one patient diagnosed with MAP were group 2 (n=128), completely involved in the treatment process of at least one patient diagnosed with MAP were group 3 (n=202).
Results: There was a significant difference between the three groups in terms of age (p<0.001), working duration in psychiatry (p<0.001), and institution and psychiatric training characteristics (p<0.001). Psychotropic preferences in insomnia (p<0.001), typical oral antipsychotic choice (p<0.001), preferred doses of olanzapine/risperidone/aripiprazole/amisulpride for maintenance treatment (p<0.001), long-acting injectable antipsychotic use practices (p<0.001), non-antipsychotic psychotropic use characteristics (p<0.001), extrapyramidal system side effect experiences (p<0.001), delirium and life-threatening situations encounter rates (p<0.001) were significantly different between group 2 and group 3. While the duration of maintenance with antipsychotics in the first MAP episode was similar between group 2 and group 3 (p=0.254), it was different in the second and subsequent MAP episodes (p<0.05). The attitudes of male and female participants were similar on almost all issues. A binary logistic regression model containing the experiences of LAI antipsychotic use, extrapyramidal system side effect and delirium was created (overall p<0.001, Nagelkerke R2=0.435; Hosmer and Lemeshow test p=0.203).
Conclusions: This first study in the field, which examines the current issue in detail, reveals that there are many factors that seriously affect psychiatrists' approaches to MAP treatment in Turkey. The most important result of this study is that psychiatrists make courageous decisions as their experience participating in all phases of MAP treatment increases.

Abstract
Background: It is known that obesity can be affected by genetic and epigenetic alterations, however little is known about the DNA methylation markers related to health promotion interventions aiming weigh loss. This study explored the effects of an 8-week integrated strength and aerobic training protocol on the DNA methylation patterns in obese women.
Methods: 13 women with a BMI of 33±2 kg/m², aged 34±5 years, underwent evaluation of body composition, waist circumference, physical performance (VO2max), and peripheral blood collection for DNA methylation analysis (EPIC Beadchip Illumina) before and after eight weeks of combined physical training intervention (3 times/week, 55 minutes/session, 70-90% of max HR).
Results: The intervention yielded noteworthy clinical enhancements, encompassing diminished waist circumference, fat mass, and increased VO2 max (p<0.05). In DNA methylation, we identified 16 Differentially Methylated Regions (DMRs) encompassing 103 CpG sites. Most of these regions were mainly located in promoters’ regions (TSS1500 and TSS200). Among the identified DMRs, 8 exhibited hypomethylation, while the remaining 8 showed hypermethylation after exercise protocol. Enrichment analysis unveiled pathways linked to cardiac, immune, and thermogenic functions.
Conclusion: Combined physical training can promote modifications in the DNA methylation profile at CpG sites in genes involved in energy metabolism pathways, increase physical performance, and reduce body fat and waist circumference. Regardless of weight loss, the exercise protocol may promote protection against cardiovascular diseases through epigenetic modifications.

Published: March 2024

Abstract
The role of potential-well width and potential-barrier height or potential-well depth in a triple-well potential on SR has not been investigated separately yet and the effect of a both uniform depth and different depth between left/right potential well and middle well in a triple-well potential on SR has not been explored yet. Meanwhile, SR is used to weak signal detection and early fault diagnosis, but it often processes a complex signal into a sine shaped one, resulting in the loss of multi-harmonic signature embedded in the raw signal. To avoid this, this paper investigates underdamped SR induced by a symmetric triple-well potential with a uniform depth. Then, a SR array based noise-boosted filter bank method is proposed to enhance weak multi-harmonic fault characteristics for early fault diagnosis of machinery. Theoretical results indicate that tristable SR induced by a symmetric triple-well potential with a uniform depth is superior to that induced by a symmetric triple-well potential with a different depth. Experimental results demonstrate that the proposed method is able to enhance weak multi-harmonic fault characteristics for early fault diagnosis of roller bearings.
The role of fines content and particle size ratio on the load-bearing structure of binary granular soil: A micromechanical approach
Authors: Nia Fatemeh Vahidi , Bayesteh Hamed , Khodaparast Mahdi 
Published: March 2024

Abstract

The particle size ratio and fines content are the most important factors influencing the behavior of binary graded granular soil. Previous studies have focused more on the effects of the fabric, particle size distribution and fines content on the macroscopic response of binary mixtures. The effect of the fines participation factor (β) on the load-bearing structure of binary graded soil and estimation of this parameter (β) from the macro and micromechanical perspectives have rarely been evaluated. The present study used a micro-mechanical approach and DEM to evaluate the global void ratio (e), intergranular void ratio (e*) and the contribution of the fines content to the load-bearing structure of binary graded soil during drained and undrained tests. The effects of the particle size ratio, fines content, initial packing density and confining pressure on β also have been evaluated. The results showed that e* is a more reliable parameter than e for interpreting the behavior of binary graded soil. In a binary graded mixture that contains coarse and fine grains, β increased non-linearly and lower values of β were obtained for denser samples. With an increase in the particle size ratio, the values of β and microscopic parameters such as the coarse-fine (C-F) particle contact decreased. The decrease in the C-F particle contact caused a decrease in β. An equation is proposed to estimate β based on the fines content and particle size ratio of the binary mixtures.

Published: March 2024

Abstract

Background
There is growing evidence of bidirectional associations between rheumatoid arthritis and adverse pregnancy outcomes (APOs) in observational studies, but little is known about the causal direction of these associations. Therefore, we explored the potential causal relationships between rheumatoid arthritis and APOs using a bidirectional two-sample Mendelian randomization (MR).
Methods
We conducted a bidirectional two-sample Mendelian randomization analysis using available summary statistics from released genome-wide association studies. Summary statistics for instrument–outcome associations were retrieved from two separate databases for rheumatoid arthritis and adverse pregnancy outcomes, respectively. The inverse-variance weighted method was used as the primary MR analysis. MR-Egger, MR pleiotropy residual sum and outlier (MR-PRESSO), and Cochran Q statistic method were implemented as sensitivity analyses approach to ensure the robustness of the results.
Results
Our study showed that a higher risk of genetically predicted rheumatoid arthritis was associated with gestational hypertension (OR: 1.04, 95%CI: 1.02–1.06), pre-eclampsia (OR: 1.06, 95%CI: 1.01–1.11), fetal growth restriction (OR: 1.08, 95%CI: 1.04–1.12), preterm delivery (OR:1.04, 95%CI: 1.01–1.07). Furthermore, we found no evidence that APOs had causal effects on rheumatoid arthritis in the reverse MR analysis. There was no heterogeneity or horizontal pleiotropy.
Conclusions
This MR analysis provides evidence of a positive causal association between rheumatoid arthritis and gestational hypertension, pre-eclampsia, fetal growth restriction and preterm delivery genetically. It highlights the importance of more intensive prenatal care and early intervention among pregnant women with rheumatoid arthritis to prevent potential adverse obstetric outcomes.
Late-onset propionic acidemia with epilepsy due to compound heterozygous variants in the PCCB gene: a case report and literature review

Published: March 2024

Abstract

Propionic acidemia is an autosomal recessively inherited metabolic disorder attributed to a mutation in the PCCA or PCCB gene resulting in a lack of propionyl coenzyme A carboxylase, which permits an abnormal accumulation of propionate and its metabolite precursors in the body. The clinical presentation and severity of propionic acidemia vary widely among patients, and late-onset propionic acidemia might manifest at any stage of life, including infancy, childhood, or even later. In this paper, a case of late-onset propionic acidemia with epilepsy caused by compound heterozygous variations of the PCCB gene was reported. The pathogenic gene, accessory examination, diagnosis, treatment, etc., were investigated, and related written works were reviewed to advance clinicians' understanding of the findings and treatment of the illness.

Abstract
To investigate the causality between high-altitude adaptation (HAA) and multiple liver diseases, we applied a Mendelian randomization (MR) study. The genome-wide association studies (GWASs) of HAA and eleven phenotypes of liver diseases/traits were used for this study, including autoimmune hepatitis (AIH), alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), hepatic bile duct cancer (BtC), chronic hepatitis-B (CHB), chronic hepatitis-C (CHC), γ-glutamyl transpeptidase (GTT), acute hepatitis by hepatitis-A virus (HAV), hepatic cancer (HepC) and total bilirubin (TBil). Our study genetically predicted a significant causal impact of HAA on GTT (odds ratio, 1.601; 95% CI, 1.204–2.129; P = 0.0012). An interesting finding emerged that the association between GGT and HAA also reached statistically significant even the causal direction was reversed (odds ratio, 1.01; 95% CI, 1.003–1.011; P = 0.0013). In conclusions, our study indicates a mutually causal association between HAA and GGT. These novel insights may facilitate the design of targeted preventive measures and therapeutic interventions for both liver diseases and the process of adapt to plateau environment.
