Authors: Vasilevski Vidanka , Ryan Denise , Crowe Grace , Askern Althea , McCormick Margie , Segond Stacey , Sweet Linda
Published: July 2023

Aim

To explore the satisfaction and experiences of women and staff with the BSOTS in an Australian hospital.

Design

Cross‐sectional descriptive survey.

Methods

Surveys were distributed to women and staff between February and May 2022. Survey questions reflected satisfaction with triage and provision of care under the BSOTS system (for women) and confidence in using the BSOTS system and its impact on triage‐related care (for staff). Survey data were summarized using descriptive statistics, and qualitative responses were analysed using content analysis.

Results

There were 50 women and 40 staff (midwives and doctors) survey respondents. Most women were satisfied with triage wait times, the verbal information they received and the time it took for them to receive care. Nearly all midwife participants indicated they had high knowledge and confidence in using the BSOTS. Most staff indicated that the BSOTS supported the accurate assessment of women and had benefits for women, staff and the hospital.

Conclusion

The findings showed that women and staff were satisfied with receiving and providing care in a maternity triage setting under the BSOTS system.

Implications for the Profession and/or Patient Care

Implementing standardized maternity triage approaches such as the BSOTS in health settings delivering care to pregnant women is recommended for improving flow of care and perceptions of care quality by women.

Impact

Quality of maternity triage processes is likely to impact the satisfaction of women attending services and the staff providing care. The BSOTS was shown to improve maternity triage processes and was associated with satisfaction of women and staff. Maternity settings can benefit from implementing triage approaches such as the BSOTS as it standardizes and justifies the care provided to women. This is likely to result in satisfaction of women and staff engaged in maternity triage and improve the birth outcomes of women and babies.

Reporting Method

The reporting of this paper has followed SQUIRE guidelines.

Patient or Public Contribution

Women engaged with maternity services were participants in the study but did not contribute to the design, conduct or publication of the study.

Electrolyzed water (EW) and ultrasound (US) treatment are emerging effective means of reducing pesticides in fresh‐cut vegetables. However, their synergetic efficacy of degrading pesticides in fresh‐cut potatoes has not yet been revealed. Therefore, in this study, the effects of the combination of EW and US treatment on the removal of pesticides (chlorpyrifos, phorate, chlorothalonil, and procymidone) in fresh‐cut potato silks, strips, slices, and dices were investigated. Acidic electrolyzed water (AcEW) was selected as the optimum washing solution for pesticide removal on fresh‐cut potatoes. For the same type of fresh‐cut potato, the AcEW treatment with different sample‐to‐washing solution ratios showed no significant difference in the removal effect of different pesticides. The combined application of AcEW and US could efficiently reduce pesticides for different fresh‐cut potatoes. Furthermore, the optimal effects obtained varied greatly within the range of ultrasonic power 200–400 W and washing time 10–20 min. These results indicated that combining AcEW with US could serve as a promising method for pesticide reduction in fresh‐cut potatoes under respective appropriate process parameters.

Practical Applications

Potato silks, strips, slices, and dices are the most common application form of fresh‐cut potatoes in Chinese dishes. Electrolyzed water (EW) and ultrasound (US) treatment have recently been used in reducing pesticides on fresh‐cut vegetables. However, their synergetic efficacy of degrading pesticides in fresh‐cut potatoes has not yet been revealed. This research provides a simple and novel method for pesticide removal on fresh‐cut potatoes. These steps combine Acidic electrolyzed water (AcEW) and US treatments to explore and improve the process parameters (sample‐to‐washing solution ratios, ultrasonic power, and washing time) of degrading pesticides for different fresh‐cut potatoes, including potato silks, strips, slices, and dices. Besides, the effect mechanism of different treatments on the degradation of pesticide residues was also discussed. The novel cleaning technology is expected to be popularized in vegetable processing plants.

Authors: Suk Jaehye , Li Xu , Hwang Hyesun
Published: July 2023

Research on consumer empowerment has evolved to reflect its requirements over time. This study aimed to trace consumer empowerment research trends through a systematic review of 245 abstracts from two esteemed journals in the field of consumer studies, namely, International Journal of Consumer Studies and Journal of Consumer Affairs. Reference network analysis revealed that research on consumer empowerment has been mainly focused on finance and education. Topic modeling revealed the following six topics: financial literacy education, school education, information competency, dietary behavior/nutrition, financial management competency, and empowerment in the market. Hot topics included financial literacy education and dietary behavior/nutrition, whereas school education was a cold topic. This study provides insights into consumer empowerment research trends and directions for future research.

Authors: Hanel Paul H. P. , Tunç Hamdullah , Bhasin Divija , Litzellachner Lukas F. , Maio Gregory R.
Published: July 2023

Objective

We investigate for the first time in a 9‐day diary study whether fulfilling one’s values predicts well‐being or whether well‐being predicts value fulfillment over time.

Background

The empirical associations between the importance of human values to individuals and their well‐being are typically weak and inconsistent. More recently, value fulfillment (i.e., acting in line with one's values) has shown to be more strongly correlated with well‐being.

Method

The present research goes beyond past research by integrating work from clinical, personality, and social psychology to model associations between value fulfillment and positive and negative aspects of well‐being over time.

Results

Across a nine‐day diary study involving 1434 observations (N = 184), we found that people who were able to fulfill their self‐direction values reported more positive well‐being on the next day, and those who fulfilled their hedonism values reported less negative well‐being on the next day. Conversely, people who reported more positive well‐being were more able to fulfill their achievement, stimulation, and self‐direction values on the next day, and those who reported more negative well‐being were less able to fulfill their achievement values. Importantly, these effects were consistent across three countries/regions (EU/UK, India, Türkiye), the importance people attributed to values, period of the week, and their prestudy well‐being.

Conclusion

These results help to understand the fundamental interconnections between values and well‐being while also having relevance to clinical practice.

Published: July 2023

Objectives

Head and neck squamous cell carcinoma (HNSCC) poses a diagnostic and therapeutic challenge worldwide and is associated with a poor survival rate. Due to the variability in the efficacy of treatments for HNSCC, new predictive biomarkers of therapy outcomes are needed. Recently, we developed an algorithm that employs the mutational profile of TP53 as an independent prognostic factor in HNSCC. In this study, we investigated its role as a predictive biomarker of treatment outcomes in HNSCC patients. We also tested the usefulness of two classification systems for TP53 mutational landscapes.

Materials and Methods

Clinical and genomic data were retrieved from The Cancer Genome Atlas database. We built a multivariate stepwise backward binary regression model to assess the role of TP53 mutations in predicting therapeutic outcomes.

Results

Cases harbouring high‐risk‐of‐death mutations reported an odds ratio of 3.301 for stable or progressive disease compared to wild‐type cases, while no significant difference in treatment outcomes was found between cases with low‐risk‐of‐death mutations and wild‐type TP53. Our analysis found that older patients with a history of alcohol consumption had a higher risk of stable/progressive disease.

Conclusions

This study improves current evidence on the role of TP53 mutations in treatment response in HNSCC patients.
Effects of regulatory burden and corruption on firm performance: Evidence from Moldova
Authors: Tan Shawn W. , Tusha Dea
Published: July 2023

Firms in Moldova face a high level of regulatory burden, as proxied by the number of inspections by public authorities. At the same time, they face high levels of corruption. We examine the effect of frequent inspections on four measures of firm performance: labour and total factor productivity, and levels of tangible and intangible assets. We also investigate how corruption affects the relationship between inspections and firm performance. We perform panel data analysis using firm‐level administrative data and survey data from Moldova in 2005–2015. The results show that inspections and corruption each affect firm productivity negatively, but corruption moderates the negative effect of inspections. We also find that inspections and intangible assets are positively correlated, but this correlation is weaker for higher levels of corruption. Finally we examine whether these results differ by industry, firm size and ownership types. Inspections and corruption affect medium and large firms, and state‐owned enterprises differently from micro and small firms and private firms respectively.

Published: July 2023

Background

Aspergillus spp. is an uncommon and life‐threatening cause of transplantrenal artery pseudoaneurysm after kidney transplantation.

Case

We report the case of a 62‐year‐old woman who underwent kidney transplantation 10 months before and presented a 7‐cm asymptomatic transplant renal artery pseudoaneurysm. Transplanted kidney and pseudoaneurysm were surgically removed in emergency. Renal graft, urine, and pseudoaneurysm cultures grew Aspergillus flavus. She recovered after 12 months of antifungal therapy.

Literature review

To date 14 cases of Aspergillus spp. renal arteritis after kidney transplantation have been published, including 50% Aspergillus flavus arteritis. Vast majority were diagnosed within 90 days after transplantation (73%). Despite allograft nephrectomy and antifungal therapy, mortality rate was high (33%).

Introduction

Expression of human complement pathway regulatory proteins (hCPRP's) such as CD46 or CD55 has been associated with improved survival of pig organ xenografts in multiple different models. Here we evaluate the hypothesis that an increased human CD46 gene dose, through homozygosity or additional expression of a second hCPRP, is associated with increased protein expression and with improved protection from injury when GTKO lung xenografts are perfused with human blood.

Methods

Twenty three GTKO lungs heterozygous for human CD46 (GTKO.heteroCD46), 10 lungs homozygous for hCD46 (GTKO.homoCD46), and six GTKO.homoCD46 lungs also heterozygous for hCD55 (GTKO.homoCD46.hCD55) were perfused with human blood for up to 4 h in an ex vivo circuit.

Results

Relative to GTKO.heteroCD46 (152 min, range 5–240; 6/23 surviving at 4 h), survival was significantly improved for GTKO.homoCD46 (>240 min, range 45–240, p = .034; 7/10 surviving at 4 h) or GTKO.homoCD46.hCD55 lungs (>240 min, p = .001; 6/6 surviving at 4 h). Homozygosity was associated with increased capillary expression of hCD46 (p < .0001). Increased hCD46 expression was associated with significantly prolonged lung survival (p = .048),) but surprisingly not with reduction in measured complement factor C3a. Hematocrit, monocyte count, and pulmonary vascular resistance were not significantly altered in association with increased hCD46 gene dose or protein expression.

Conclusion

Genetic engineering approaches designed to augment hCPRP activity — increasing the expression of hCD46 through homozygosity or co‐expressing hCD55 with hCD46 — were associated with prolonged GTKO lung xenograft survival. Increased expression of hCD46 was associated with reduced coagulation cascade activation, but did not further reduce complement activation relative to lungs with relatively low CD46 expression. We conclude that coagulation pathway dysregulation contributes to injury in GTKO pig lung xenografts perfused with human blood, and that the survival advantage for lungs with increased hCPRP expression is likely attributable to improved endothelial thromboregulation.

Published: July 2023

Teacher education programs are established to create opportunities for preservice teachers to learn actively through course work and practicum experiences. This mixed methods study looked to understand preservice perceptions of their program post covid and to assess their perceived proficiency as an educator, by examining expectations placed on preservice teachers to indicate that there is a gap in their understanding of important concepts related to pedagogy and their application of best practices. The preservice teacher survey indicated a positive experience during their practicum experiences but the skill application for behavior management, flexibility, and classroom processes indicated limited experience and little empathetic understanding. The aim of this study is to reevaluate teacher education programs to better support and provide authentic opportunities for pedagogical skill development before graduation.

Authors: Negruțiu Mircea , Danescu Sorina , Popa Theodor , Baican Adrian
Published: July 2023

Skin ultrasound (US) is a relatively new imaging technique, for which interest has grown significantly in the last decade. Properties such as mobility, real-time imaging and lack of irradiation or sedation, have made it a useful tool in completing the clinical examination. The use of probes of different frequencies has managed to improve the US technique, offering the possibility of obtaining high quality images. Thus, by using high-frequency and ultra-high frequency US, subclinical information can be obtained with a wide applicability in dermatological pathology. In this paper we aim to discuss the main uses of skin US in non-tumoral pathology (inflammatory and autoimmune pathology).

Authors: Jahandideh Leila , Letafatkar Amir , Khanzadeh Reza , Omidi Kashani Farzad
Published: July 2023

Context: Hip muscle imbalance, especially between gluteal muscles and tensor fasciae latae (TFL), is one of the risk factors for developing low back pain which should be considered in rehabilitation programs. This study compared the effect of exercises with gluteal-to-TFL muscle activation index above and below 50 on pain intensity, disability, and lower limbs’ range of motion (ROM) in patients with nonspecific chronic low back pain. Design: A semiexperimental intervention study with a pretest and posttest. Methods: A total of 45 patients with nonspecific chronic low back pain were randomly divided into 2 experimental groups of gluteal-to-TFL muscle activation index above 50 (n = 15), below 50 (n = 15), and a control group (n = 15). Pain intensity (visual analog scale), disability (Roland–Morris Disability Questionnaire), and lower limbs’ ROM including hip extension, hip abduction, hip external rotation, and knee extension (goniometer) were assessed at pretest and after 8 weeks of intervention. Results: Within-group comparison showed significant improvement of pain, disability, and ROMs in both experimental groups. No significant changes were observed in the control group. In between-group analysis, significant differences were observed in group of gluteal-to-TFL muscle activation index above 50 for only pain (P = .03) and disability (P = .01). For ROMs, although clinical improvement of lower limbs’ ROMs was higher in group of gluteal-to-TFL muscle activation index above 50, no statistically significant differences were found between 2 experimental groups. Both experimental groups were superior to the control group for all outcomes. Conclusions: Findings indicate the statistically and clinically superior effectiveness of exercises with a gluteal-to-TFL muscle activation index above 50 in the reduction of pain and disability. Based on the clinical significance of exercises with a gluteal-to-TFL muscle activation index above 50 for improving ROMs, utilizing specific exercises that more activated gluteal muscle compared to TFL is recommended for patient with restricted lower limbs’ ROMs.

Published: July 2023

Proprioception is essential for precise movement as it helps the body transmit important data about its surroundings to the central nervous system for maintaining body posture and position. This study aimed to investigate the effect of direction and joint angle on upper limb proprioception. Thirty individuals (all males) completed a position reproduction activity in 13 directions and three joint angles. It was discovered that upper limb proprioception is dependent on joint angle, direction, and range of motion. The position reproduction error was found to be dependent on the direction, which had a significantly lower accuracy in the direction with a larger range of motion. In addition, upper limb repositioning errors increased at greater limb elevation angles. Our findings also showed that the joint angle did not significantly affect the absolute error of elbow flexion. With an increase in the elbow flexion, the increase of the gravitational moment of the upper arm and hand coupled with the increase of the muscle arm of the biceps brachii possibly causes slight changes in muscle length perceived by spindles or muscular force perceived by Golgi tendon organs.

The megajansky radio burst, FRB 20200428, and other bright radio bursts detected from the Galactic source SGR J1935+2154 suggest that magnetars can make fast radio bursts (FRBs), but the emission site and mechanism of FRB-like bursts are still unidentified. Here, we report the emergence of a radio pulsar phase of the magnetar 5 months after FRB 20200428. Pulses were detected in 16.5 hours over 13 days using the Five-hundred-meter Aperture Spherical radio Telescope, with luminosities of about eight decades fainter than FRB 20200428. The pulses were emitted in a narrow phase window anti-aligned with the x-ray pulsation profile observed using the x-ray telescopes. The bursts, conversely, appear in random phases. This dichotomy suggests that radio pulses originate from a fixed region within the magnetosphere, but bursts occur in random locations and are possibly associated with explosive events in a dynamically evolving magnetosphere. This picture reconciles the lack of periodicity in cosmological repeating FRBs within the magnetar engine model.
Ubiquitination of acetyltransferase Gcn5 contributes to fungal virulence in
Fusarium graminearum
Authors: Chen Ahai , Zhou Yifan , Ren Yiyi , Liu Chao , Han Xingmin , Wang Jing , Ma Zhonghua , Chen Yun
Published: July 2023

The histone acetyltransferase general control non-depressible 5 (Gcn5) plays a critical role in the epigenetic landscape and chromatin modification for regulating a wide variety of biological events. However, the post-translational regulation of Gcn5 itself is poorly understood. Here, we found that Gcn5 was ubiquitinated and deubiquitinated by E3 ligase Tom1 and deubiquitinating enzyme Ubp14, respectively, in the important plant pathogenic fungus
Fusarium graminearum
. Tom1 interacted with Gcn5 in the nucleus and subsequently ubiquitinated Gcn5 mainly at K252 to accelerate protein degradation. Conversely, Ubp14 deubiquitinated Gcn5 and enhanced its stability. In the deletion mutant Δ
ubp14
, protein level of Gcn5 was significantly reduced and resulted in attenuated virulence in the fungus by affecting the mycotoxin production, autophagy process, and the penetration ability. Our findings indicate that Tom1 and Ubp14 show antagonistic functions in the control of the protein stability of Gcn5 via post-translational modification and highlight the importance of Tom1-Gcn5-Ubp14 circuit in the fungal virulence.

IMPORTANCE

Post-translational modification (PTM) enzymes have been reported to be involved in regulating numerous cellular processes. However, the modification of these PTM enzymes themselves is largely unknown. In this study, we found that the E3 ligase Tom1 and deubiquitinating enzyme Ubp14 contributed to the regulation of ubiquitination and deubiquitination of acetyltransferase Gcn5, respectively, in
Fusarium graminearum
, the causal agent of Fusarium head blight of cereals. Our findings provide deep insights into the modification of acetyltransferase Gcn5 and its dynamic regulation via ubiquitination and deubiquitination. To our knowledge, this work is the most comprehensive analysis of a regulatory network of ubiquitination that impinges on acetyltransferase in filamentous pathogens. Moreover, our findings are important because we present the novel roles of the Tom1-Gcn5-Ubp14 circuit in fungal virulence, providing novel possibilities and targets to control fungal diseases.

Authors: Singh Pardeep
Published: July 2023

Composite particle, [Formula: see text], charge exchange reactions on targets [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text] at 140 MeV/u beam energy have been analyzed by employing distorted wave impulse approximation (DWIA). Specifically, unit cross-section and angular distribution have been calculated using normal optical model potential (NOMP) and single folding optical model potential (SFOMP) for both relativistic and non-relativistic cases. The sensitivity of present results on exchange terms has also been examined and it is pertinent to report here that the inclusion of these effects reduces the cross-section in magnitude up to 60%, which in turn brings it closer to the data except for [Formula: see text].
Nonlinear thermal radiation effect on magnetohydrodynamics flow of Cu−H2O and TiO2−H2O of Casson nanofluids over stretching wall through porous channel
Authors: Varatharaj K. , Tamizharasi R.
Published: July 2023

This paper presents a numerical solution for the nonlinear thermal radiation effect of magnetohydrodynamic flow of Casson nanofluid over a stretching wall through a porous channel. As the linear thermal radiation leads to a significant difference between the highest and lowest possible temperatures, the nonlinear thermal radiation is used in this work. The governing partial differential equations are changed into nonlinear ordinary differential equations using similarity transformation and then solved using the Runge–Kutta method together with the shooting technique. The graphical representation of the temperature and the velocity profiles is presented for different values of the parameters involved in the problem. The obtained results of the skin friction and the heat transfer are compared with the results in the literature and achieved an excellent agreement.
Depth-Constrained Network for Multi-Scale Object Detection
Authors: Liu Guohua , Li Yijun
Published: July 2023

Challenges such as complex backgrounds, drastic variations in target scales, and dense distributions exist in natural scenes. Some algorithms optimize multi-scale object detection performance by combining low-level and high-level information through feature fusion strategies. However, these methods overlook the inherent spatial properties of objects and the relationships between foreground and background. To fundamentally enhance the multi-scale detection capability, we propose a depth-constrained multi-scale object detection network that simultaneously learns object detection and depth estimation through a unified framework. In this network, depth features are merged into the detection branch as auxiliary information and constrained and guided to obtain better spatial representations, which enhances discrimination between multi-scale objects. We also introduce a novel cross-modal fusion (CmF) strategy that utilizes depth awareness and low-level detail clues to supplement edge information and adjust attention weight preferences. We find complementary information from RGB and high-quality depth features to achieve better multi-modal information fusion. Experimental results demonstrate that our method outperforms state-of-the-art methods on the KINS dataset, with an improvement of 3.0% in AP score over the baseline network. Furthermore, we validate the effectiveness of our proposed method on the KITTI dataset.
Multi-OCDTNet: A Novel Multi-Scale Object Context Dilated Transformer Network for Retinal Blood Vessel Segmentation
Authors: Wu Chengwei , Guo Min , Ma Miao , Wang Kaiguang
Published: July 2023

Image segmentation is an essential part of medical image processing, which plays a significant role in adjunctive therapy, disease diagnosis, and medical assessment. To solve the problem of insufficient extracting context information, especially for medical image segmentation, this paper proposes a novel network architecture of multi-scale object context dilated transformer network (Multi-OCDTNet) to improve the utilization and segmentation accuracy for context information. The multi-scale object context transformer module can extract the multi-scale context information of the image through a three-layer transformer structure in a parallel way. The dilated convolution self-aware module can enhance the awareness of multi-scale context information in the feature map through layering transformer block groups and a set of transformer layers. In addition, we propose a composite weight-assigned-based loss function based on DDCLoss and Focal Tversky Loss to improve the stability of the segmentation performance of Multi-OCDTNet by adjusting the weight. The performance of Multi-OCDTNet is validated on the DRIVE and STARE datasets with segmentation accuracy of 97.17% and 97.84%, respectively, indicating the Multi-OCDTNet network possesses a significant competitive advantage in improving the segmentation performance of retinal vessel images.
PERFORMANCE ENHANCEMENT OF BRASS EDM ELECTRODES WITH CRYOGENIC TREATMENT WHILE MACHINING THE COLD WORK STEEL AISI D2
Authors: ÇAKIR FATIH HAYATI , CERITBINMEZ FERHAT
Published: July 2023

This study investigates the performance of deep cryogenically treated brass (CuZn25Al5) electrodes in the die-sink EDM process. Two different cryogenic treatment durations, 6 h and 12 h, were applied to 8 mm diameter electrodes, and their effects were compared to untreated electrodes. The machining tests were conducted under moderate and aggressive conditions. In the machining tests, the 6-h cryo-treated electrode exhibited a 16.8% increase in material removal rate (MRR) under moderate conditions and a 19.7% increase under aggressive conditions compared to the reference electrode. The 12-h cryo-treated electrode showed similar MRR values to the reference electrode but improved tool wear resistance by 9.4% under moderate conditions. The kerf angle was minimized, indicating better hole verticality, in the 6-h cryo-treated electrode group. The improvement in machining performance was attributed to the enhancement in electrical conductivity of the electrodes, which increased by 28% for the 6-h cryo-treated electrode and 20% for the 12-h cryo-treated electrode. X-ray diffraction (XRD) analysis revealed shifts in peak positions and possible phase transformations due to cryogenic treatment. Surface roughness measurements showed improved surface conditions in the cryo-treated electrodes under aggressive conditions. The results indicate that cryogenic treatment enhances MRR, reduces tool wear, and improves surface quality in die-sink EDM. These improvements are attributed to increased electrical conductivity and changes in the internal structure of the brass electrode.
A biorthogonal approach to the infinite dimensional fractional Poisson measure
Authors: Bendong Jerome B. , Menchavez Sheila M. , da Silva José Luís
Published: July 2023

In this paper, we use a biorthogonal approach to the analysis of the infinite dimensional fractional Poisson measure [Formula: see text], [Formula: see text], on the dual of Schwartz test function space [Formula: see text]. The Hilbert space [Formula: see text] of complex-valued functions is described in terms of a system of generalized Appell polynomials [Formula: see text] associated to the measure [Formula: see text]. The kernels [Formula: see text], [Formula: see text], of the monomials may be expressed in terms of the Stirling operators of the first and second kind as well as the falling factorials in infinite dimensions. Associated to the system [Formula: see text], there is a generalized dual Appell system [Formula: see text] that is biorthogonal to [Formula: see text]. The test and generalized function spaces associated to the measure [Formula: see text] are completely characterized using an integral transform as entire functions.
Analogues of Poisson-type limit theorems in discrete bm-Fock spaces
Authors: Oussi Lahcen , Wysoczański Janusz
Published: July 2023

In this paper, we present analogues of the Poisson limit distribution for the noncommutative bm-independence, which is associated with several positive symmetric cones. We construct related discrete Fock spaces with creation, annihilation and conservation operators, and prove Poisson type limit theorems for them. Properties of the positive cones, in particular the volume characteristic property they enjoy, and the combinatorics of labeled noncrossing partitions, play crucial role in these considerations.

Published: July 2023

The field load test is a direct and effective method for evaluating the performance of bridge structures. However, the existing bridge static load tests on site are costly, inefficient, and obstruct traffic; moreover, improper loading may also cause some damage to the bridge structure. This paper proposes a random model update method based on bridge dynamic load tests and the Bayesian inference as an alternative to the static load test. The Gaussian process model was used instead of the finite element model to reduce the cost of model calculation. Furthermore, choose the Markov Chain Monte Carlo (MCMC) method based on delay rejection adaptive Metropolis algorithm for Bayesian inference to improve the speed of the Bayesian method inferring the posterior probability density of updated parameters. First, the parameters to be updated for the bridge structure analysis model were determined based on the global sensitivity analysis method. Second, a uniform design sampling method was used to establish the Gaussian process optimization model to update the random model of the bridge structure. Finally, a reinforced concrete truss arch bridge was used to verify the correctness of the static load results of the bridge predicted by the random model update method based on dynamic load testing and Bayesian inference. The results show that the predicted results of the bridge static load test based on the dynamic load test and Bayesian reasoning method have an excellent agreement with the measured results, and this method can effectively overcome the adverse effects of the existing bridge static load test.
Superintegrability, symmetry and point particle T-duality
Authors: Klimčík Ctirad
Published: July 2023

We show that the ideas related to integrability and symmetry play an important role not only in the string T-duality story but also in its point particle counterpart. Applying those ideas, we find that the T-duality seems to be a more widespread phenomenon in the context of the point particle dynamics than it is in the string one; moreover, it concerns physically very relevant point particle dynamical systems and not just somewhat exotic ones fabricated for the purpose. As a source of T-duality examples, we consider maximally superintegrable spherically symmetric electro-gravitational backgrounds in [Formula: see text] dimensions. We then describe in detail four such spherically symmetric dynamical systems which are all mutually interconnected by a web of point particle T-dualities. In particular, the dynamics of a charged particle scattered by a repulsive Coulomb potential in a flat space is T-dual to the dynamics of the Coulomb scattering in the space of constant negative curvature, but it is also T-dual to the (conformal) Calogero–Moser inverse square dynamics both in flat and hyperbolic spaces. Thus knowing just the Hamiltonian dynamics of the scattered particle cannot give us information about the curvature of the space in which the particle moves.

Published: July 2023

We discuss generalizations of the notions of projective transformations acting on affine model of Riemann–Cartan and Riemann–Cartan–Weyl gravity which preserve the projective structure of the light-cones. We show how the invariance under some projective transformations can be used to recast a Riemann–Cartan–Weyl geometry either as a model in which the role of the Weyl gauge potential is played by the torsion vector, which we call torsion-gauging, or as a model with traditional Weyl (conformal) invariance.

Published: July 2023

This work aims to investigate the effects of magnetic field and inclined load on a two-dimensional thermoelastic medium under gravitational field. The problem is formulated in the context of refined dual-phase-lag Green–Naghdi (DPL GN) model. The bounding plane surface is heated by a non-Gaussian laser beam. The inclined load is supposed to be a linear combination of a normal load and a tangential load. Analytical formulas for several physical quantities are generated on the transformed domain using the Laplace and Fourier transform techniques. The inversion of double transform has been done numerically by using MATHEMTICA 10. The numerical inversion of Laplace transform is done by using the Zakian method (Halsted and Brown [Zakians technique for inverting Laplace transforms, J. Chem. Eng. 3 (1972) 312–313]). All physical quantities have been graphically depicted for the dual-phase-lag Green–Naghdi type III model (DPL GN-III), simple Green–Naghdi type III model (simple GN-III), Lord–Shulman model (LS) and classical thermoelasticity theory (CTE) to indicate the effect of magnetic field and the angle of inclination of the medium.

Magnetic field-assisted drug delivery is a fascinating strategy to transport chemotherapeutic drugs. Ferrite nanoparticles (NPs) of the form MFe2O4 are a good choice for utilization as magnetic nanocarriers. Although many ferrite NPs have been tested for their function as nanocarriers, their nonspecific toxicity must be minimized. In this work, calcium–nickel ferrite nanoparticles (CNF MNPs) coated with dextran–[Formula: see text]-cyclodextrin and dextran–[Formula: see text]-cyclodextrin–dextran polymers are reported. The synthesized NPs are characterized using XRD, TEM, EDX and XPS. The magnetic properties are investigated by vibrating sample magnetometry. The 20 nm-sized CNF MNPs fall in the size range suitable for cancer drug transport. The magnetic nanocarriers containing the polymers are superparamagnetic. The camptothecin (CPT) loading efficiency is observed as 88%. The in vitro CPT release profiles are sustained, displaying a continuous release for a period of above 45 h. The cytotoxicity studies on A549 cell lines reveal that the CPT-loaded CNF MNPs are active against them and can be used as an anticancer drug carrier.

Ferroelectric nanocapacitors have attracted intensive research interest due to their novel functionalities and potential application in nanodevices. However, due to the lack of knowledge of domain evolution in isolated nanocapacitors, precise manipulation of topological domain switching in the nanocapacitor is still a challenge. Here, we report unique bubble and cylindrical domains in the well-ordered BiFeO3 nanocapacitor array. The transformation of bubble, cylindrical and mono domains in isolated ferroelectric nanocapacitor has been demonstrated via scanning probe microscopy (SPM). The bubble domain can be erased to mono domain or written to cylindrical domain and mono domain by positive and negative voltage, respectively. Additionally, the domain evolution rules, which are mainly affected by the depolarization field, have been observed in the nanocapacitors with different domain structures. This work will be helpful in understanding the domain evolution in ferroelectric nanocapacitors and providing guidance on the manipulation of nanoscale topological domains.
Study of the Mixed Spin Ising Nanowire with Random and Dilute Crystal Field

Published: July 2023

The mixed spin Ising nanowire with random and dilute crystal fields has been explored based on the finite cluster approximation. Much concern has been addressed in treating the effects of the randomness with two distribution types of the crystal field on the phase diagrams. It has been demonstrated that for a low random crystal field D marked by the fluctuation d, all transition lines are of second order and are not particularly sensitive to the fluctuation; whereas, for high values of D, the transition temperature depends on the fluctuation and may display tricritical points. Under the effect of the dilute crystal field, according to the surface shell coupling strength, the tricritical behavior occurs exclusively for higher values of the concentration p where a large majority of spins are influenced by the crystal field. All these behaviors have been confirmed by examination of magnetizations.

Published: July 2023

Background: The human hand is a specialised organ for fine motion and sensation and has a relatively large representation in the homunculus. The pathway of sensation starts from information sent by mechanoreceptors in the hand. This study reports the topography of the Pacinian corpuscle in the fingertips of a human cadaver.

Methods: All 10 digits from both hands of a fresh-frozen cadaver were examined. Glabrous skin distal to the distal interphalangeal joint was harvested superficial to the periosteum including fat and subcutaneous tissue. The glabrous skin were divided into 10 sections that included five distal and five proximal sections. Modified gold chloride staining was performed. Sectioned specimens were observed under a light microscope and the density of Pacinian corpuscles was determined in each segment. The density of the corpuscles was compared between the radial/ulnar and proximal/distal segments and also between digits from the right hand versus those from the left hand.

Results: Pacinian corpuscles were observed only in the subcutaneous tissue. There was no significant difference in density of the corpuscles between the distal and proximal segments or between the right and left hands. There was a statistically significant greater density of Pacinian corpuscles on the radial segments of all digits except the thumb.

Conclusions: There is a greater density of Pacinian corpuscles on the radial side of the human fingertip in all digits except the thumb.
Opponensplasty for Severe Carpal Tunnel Syndrome with the Transfer of the Palmaris Longus Tendon to the Rerouted Extensor Pollicis Brevis Tendon
Authors: KIMORI Kenji , HACHISUKA Hiroki
Published: July 2023

The authors describe a novel opponensplasty for severe carpal tunnel syndrome that uses the palmaris longus (PL) tendon transferred to the rerouted extensor pollicis brevis (EPB) tendon with pulley reconstruction using a portion of the PL tendon simultaneously with the carpal tunnel release. Like the Camitz opponensplasty, this technique utilises the PL as the motor source, does not require special postoperative treatment and enables fast functional recovery even in older patients. Compared with the Camitz procedure, this technique can easily acquire thumb rotation without tendon bowstringing. Furthermore, because the function of the EPB tendon is preserved, the tendency of flexion in the thumb metacarpophalangeal (MP) joint is not observed after surgery, and improvement can be expected in patients with preoperative MP joint extension lag. This technique is a useful alternative to the Camitz procedure, as it overcomes the disadvantages of the Camitz procedure while preserving the advantages.
