Published: February 2024

The dynamic nature of the microtubule network is dependent in part by post-translational modifications (PTMs) — particularly through acetylation, which stabilizes the microtubule network. Whether PTMs of the microtubule network in vascular smooth muscle cells (VSMCs) contribute to the pathophysiology of hypertension is unknown. The aim of this study was to determine the acetylated state of the microtubule network in the mesenteric arteries of spontaneously hypertensive rats (SHR). Experiments were performed on male normotensive rats and SHR mesenteric arteries. Western blotting and mass spectrometry determined changes in tubulin acetylation. Wire myography was used to investigate the effect of tubacin on isoprenaline-mediated vasorelaxations. Isolated cells from normotensive rats were used for scanning ion conductance microscopy (SICM). Mass spectrometry and Western blotting showed that tubulin acetylation is increased in the mesenteric arteries of the SHR compared with normotensive rats. Tubacin enhanced the β-adrenoceptor-mediated vasodilatation by isoprenaline when the endothelium was intact, but attenuated relaxations when the endothelium was denuded or nitric oxide production was inhibited. By pre-treating vessels with colchicine to disrupt the microtubule network, we were able to confirm that the effects of tubacin were microtubule-dependent. Using SICM, we examined the cell surface Young's modulus of VSMCs, but found no difference in control, tubacin-treated, or taxol-treated cells. Acetylation of tubulin at Lys40 is elevated in mesenteric arteries from the SHR. Furthermore, this study shows that tubacin has an endothelial-dependent bimodal effect on isoprenaline-mediated vasorelaxation.
Unearthing the role of septins in viral infections

Published: February 2024

Septin proteins are a subfamily of closely related GTP-binding proteins conserved in all species except for higher plants and perform essential biological processes. Septins self-assemble into heptameric or octameric complexes and form higher-order structures such as filaments, rings, or gauzes by end-to-end binding. Their close association with cell membrane components makes them central in regulating critical cellular processes. Due to their organisation and properties, septins function as diffusion barriers and are integral in providing scaffolding to support the membrane’s curvature and stability of its components. Septins are also involved in vesicle transport and exocytosis through the plasma membrane by co-localising with exocyst protein complexes. Recently, there have been emerging reports of several human and animal diseases linked to septins and abnormalities in their functions. Most of our understanding of the significance of septins during microbial diseases mainly pertains to their roles in bacterial infections but not viruses. This present review focuses on the known roles of septins in host–viral interactions as detailed by various studies.
Transcriptional repression across mitosis: mechanisms and functions
Authors: Contreras A. , Perea-Resa C.
Published: February 2024

Transcription represents a central aspect of gene expression with RNA polymerase machineries (RNA Pol) driving the synthesis of RNA from DNA template molecules. In eukaryotes, a total of three RNA Pol enzymes generate the plethora of RNA species and RNA Pol II is the one transcribing all protein-coding genes. A high number of cis- and trans-acting factors orchestrates RNA Pol II-mediated transcription by influencing the chromatin recruitment, activation, elongation, and/or termination steps. The levels of DNA accessibility, defining open-euchromatin versus close-heterochromatin, delimits RNA Pol II activity as well as the encounter with other factors acting on chromatin such as the DNA replication or DNA repair machineries. The stage of the cell cycle highly influences RNA Pol II activity with mitosis representing the major challenge. In fact, there is a massive inhibition of transcription during the mitotic entry coupled with chromatin dissociation of most of the components of the transcriptional machinery. Mitosis, as a consequence, highly compromises the transcriptional memory and the perpetuation of cellular identity. Once mitosis ends, transcription levels immediately recover to define the cell fate and to safeguard the proper progression of daughter cells through the cell cycle. In this review, we evaluate our current understanding of the transcriptional repression associated with mitosis with a special focus on the molecular mechanisms involved, on the potential function behind the general repression, and on the transmission of the transcriptional machinery into the daughter cells. We finally discuss the contribution that errors in the inheritance of the transcriptional machinery across mitosis might play in stem cell aging.
Electrical tree degradation of MgO/epoxy resin composites at different voltage frequencies
Authors: Zhang Yunxiao , Lin Wenxin , Zhou Yuanxiang , Xing Weiwei , Cheng Jiayu , Teng Chenyuan
Published: February 2024

Electrical tree degradation is one of the main causes of insulation failure in high‐frequency transformers. Electrical tree degradation is studied on pure epoxy resin (EP) and MgO/EP composites at frequencies ranging from 50 Hz to 130 kHz. The results show that the tree initiation voltage of EP decreases, while the growth rate and the expansion coefficient increase with frequency. Moreover, the bubble phenomenon at high frequencies in EP composites is discussed. Combined with trap distribution characteristics within the material, the intrinsic mechanism of epoxy composites to inhibit the growth of the electrical tree at different frequencies is discussed. It can be concluded that more deep traps and blocking effect are introduced by doping nano‐MgO into EP bulks, which can improve the electrical tree resistance performance of EP composites in a wide frequency range.
A fast and structurally simple control scheme based on a fuzzy supervisory approach for wireless power transfer systems
Authors: Kiyani Mohammadreza , Abdollahi Seyed Ehsan , Baigzadehnoe Barmak , Abdollahi Seyed Reza
Published: February 2024

Wireless power transfer (WPT) is a promising technology and has attracted many researchers’ attention due to its inherent advantages such as reliability, safety, flexibility, and low maintenance costs. For WPT systems, the output voltage varies according to the variable loads and the coupling coefficient conditions, affecting system stability and efficiency. In this regard, this study is concerned with the tracking control problem of WPT systems based on fuzzy supervisory proportional–integral (PI) controller and a phase shift modulation technique, which is for the first time proposed by this paper. By introducing appropriate fuzzy rules, the proposed control scheme not only can track the desired output voltage but also has better robust behaviour to deal with the problem of variations of circuit elements and coupling coefficients. That is, the proposed fuzzy supervisory PI control scheme can perform better than the traditional PI controller. Analysis of the designed control method and simulation results validate the superiority of the proposed method over the traditional PI controller in all conditions, which can make it a suitable choice for the applications of electric vehicle charging systems. The analysis is supported by experimental measurements.
The origin of cold gas in the circumgalactic medium
Authors: Decataldo Davide , Shen Sijing , Mayer Lucio , Baumschlager Bernhard , Madau Piero
Published: February 2024

Context. The presence of cold gas (T ≲ 104 K) in the circumgalactic medium (CGM) of galaxies has been confirmed in observations and in high-resolution simulations, but its origin is still a puzzle. Possible mechanisms are cold accretion from the intergalactic medium (IGM), clumps embedded in outflows and transported from the disk, and gas detaching from the hot CGM phase via thermal instabilities.

Aims. In this work we characterize the history of cold CGM gas in order to identify the dominant origin channels at different evolutionary stages of the main galaxy.

Methods. To this end, we tracked gas particles in different snapshots of the smoothed particle hydrodynamics (SPH) cosmological zoom-in simulation Eris2k. We performed a backward tracking of cold gas, starting from different redshifts until we could identify one of the followings origins for the particle: cold inflow, ejection from the disk, cooling down in situ, or stripping from a satellite. We also performed a forward tracking of gas in different components of the galaxy (such as the disk and outflows).

Results. We find a clear transition between two epochs. For z > 2, most cold gas (up to 80%) in the CGM comes from cold accretion streams as the galaxy is accreting in the cold mode from the IGM. At lower z, gas either cools down in situ after several recycles (with 10–20% of the gas cooling in outflow), or it is ejected directly from the disk (up to 30%). Outflows have a major contribution to the cold CGM gas budget at z < 1, with almost 50% of the hot gas cooling in outflow. Finally, we discuss possible mechanisms for CGM cooling, showing that the thermally unstable gas with tcool/tff < 1 (precipitation-regulated feedback) is abundant up to r ∼ 100 kpc and cooling times are shorter than 50 Myr for densities n > 10−2 cm−3.
The search for DA double white dwarf binary candidates from SDSS DR14

Published: February 2024

Aims. Double white dwarf (DWD) binaries are one of the channels through which type Ia supernovae explosions occur. With the release of more and more sky survey data, the search for additional DWDs has become a possibility. We utilized the spectroscopic data from SDSS DR14 to search for DWD binaries based on variations in radial velocities (RVs).

Methods. We obtained a sample of 4089 DA white dwarfs (WDs) with two or more spectra from SDSS DR14, and their RVs were derived using the cross-correlation function. Using the chi-squared (χ2) distribution of RVs as a base, we calculated the corresponding logarithmic probabilities (log p) for different degrees of freedom.

Results. We selected the targets with log p < −3.0 and obtained 65 highly credible DWD candidates, of which 56 were newly discovered. We compared the distributions of the Teff, log g, and mass of the DWD candidates and found that the mass distribution of DWDs has two peaks. The primary peak, located at 0.45 M⊙, is lower than the peak of the total WD sample, while the secondary peak, located at 0.60 M⊙, is similar to the peak of the total sample. Finally, we crossmatched our sample with Zwicky Transient Facility (ZTF) photometry data and identified two targets with clear periodic variability. Based on the shape of their light curve, we think both could be white dwarf main-sequence binary stars

Globular clusters (GCs), as old as our Galaxy, constantly lose their members to the field as they cross through the Milky Way (MW). These escaped GC stars (or escapees) are thought to contribute significantly to the MW halo. If a star left the host GC a long time ago, chemical finger prints (e.g., N enrichment) may reveal its origin. In this work we aim to establish dynamical connections between N-rich field stars recently identified by LAMOST and the existing MW GCs. By constructing the full action distribution in combination with metallicity, we found 29 potential GC progenitors for 15 N-rich field stars. In particular, some of them may be related to MW accretion events. On the other hand, if a star has recently left its host GC via tidal evaporation, it still maintains the kinematic properties of the cluster. Here we identify extra-tidal candidates based on their spatial locations, proper motions (PMs), and their positions on color-magnitude diagrams (CMDs). We successfully identified more than 1600 extra-tidal candidates in the vicinity of six Gaia-Enceladus (GE)-related GCs: NGC 1851, NGC 1904, NGC 6205, NGC 6341, NGC 6779, NGC 7089. The density map of the extra-tidal candidates is confirmed to be an efficient way to find extra-tidal structures. The two possible density peaks at opposite sides of the inner boundary is a good indicator for a long stellar stream. Among 95 extra-tidal candidates with spectroscopic radial velocities and metallicity, 54 of them are confirmed to be GC escaped stars as they share similar properties to host GCs. These extra-tidal candidates are ideal targets for follow-up spectroscopic observation as it greatly improves the scientific outcome. Once a statistically significant number of spectroscopic radial velocities and metallicities are available, the GC dynamical evolution (e.g., mass loss, rotation) can be carefully investigated.
Growth and evolution of low-mass planets in pressure bumps
Authors: Pierens Arnaud , Raymond Sean N.
Published: February 2024

Observations of protoplanetary disks have revealed dust rings that are likely due to the presence of pressure bumps in the disk. Because these structures tend to trap drifting pebbles, it has been proposed that pressure bumps may play an important role in the planet formation process. In this paper, we investigate the orbital evolution of a 0.1 M⊕ protoplanet embedded in a pressure bump using 2D hydrodynamical simulations of protoplanetary disks consisting of gas and pebbles. We examine the role of thermal forces generated by the pebble accretion-induced heat release, taking into account the feedback between the luminosity and the eccentricity. We also study the effect of the pebble-scattered flow on the planet’s orbital evolution. Due to the accumulation of pebbles at the pressure bump, the planet’s accretion luminosity is high enough to induce significant eccentricity growth through thermal forces. Accretion luminosity is also responsible for vortex formation at the planet’s position through baroclinic effects, which cause the planet to escape from the dust ring if dust feedback on the gas is neglected. Including the effect of the dust feedback leads to weaker vortices, which enable the planet to remain close to the pressure maximum on an eccentric orbit. Simulations in which the planet mass is allowed to increase as a consequence of pebble accretion result in the formation of giant planet cores with masses in the range of 5–20 M⊕ over ~2 × 104 yr. This occurs for moderate values of the Stokes number, St ≈ 0.01, such that the pebble drift velocity is not too high and the dust ring mass not too small. Our results suggest that pressure bumps mays be preferred locations for the formation of giant planets, but this requires a moderate level of grain growth within the disk.

Anatomy of the Mandibular Ramus of the Facial Nerve-based upon a study of 126 cervicofacial halves
Authors: Dass Dr. Ramji , Thapar Dr. S. P. , Singh Dr. Ravinder Pal
Published: February 2024

This paper presents the anatomical data relating to the mandibular ramus of facial nerve studied by meticulous dissection on 126 cervicofacial halves of cadavers. While reviewing the applied anatomy of this nerve it was observed that the description given in the standard text books of Anatomy including those of Surgical Anatomy is rather fragmentary and inadequate and is not in conformity with the present data. The nerve is constantly a branch of cervicofacial division of facial nerve and has been invariably found a little below and behind the gonion. However, it was observed abutting the angle or even placed deep to it when the angle is everted. The ramus is not a solitary fasciculus but is made up of a number of filaments inter-communicating with each other before converging to form a single, a double or even triple twigs. In relation to the external surface of body of mandible, it may lie either on the outer surface just above the lower border or all along its inferior border and sometimes even looping down in the diagastric triangle with its terminal part ascending upward to enter the facial region at the antero-inferior angle of the masseter muscle. Here it is closely related to facial artery and its accompaying anterior facial vein, with its ramifications in between these structures to end in the muscles acting on the lower lip.

The variationi n the anatomical data thus worked out will add to the knowledge of those dealing with problems iike facial palsy and like wise the specialists handing the facio-maxillary injuries.

Bilateral Fan flap in Reconstruction of Lower Lip—A Case Report
Authors: Bafna P. L. , Baid J. C. , Mehta R. M.
Published: February 2024

The bilateral fan flap has the following advantages over other meihods :—

1. The lip so formed does not narrow the oral aperture.

2. As the flap contains muscle it does not droop down by gravity as in case of tube pedicle repairs.

3. By virtue of providing a symmetrical half of the lip from either flap and by leaving behind symmetrical scars on the face it gives a better cosmetic appearance.

4. Unlike uailateral fan flaps the blood supply in the twin flaps is less extended and the secondary defect is more evenly distributed on the face. It is as such to be preferred over the unilateral method.

Authors: Shinde Sandeep B. , Jain Pooja P. , Jagwani Diksha S. , Patil Sanjay K. , Gudur Anand , Shinde Ravindra V.
Published: February 2024

Breast cancer (BC) is one of the most frequent cancers in women, and breast cancer-related lymphedema (BCRL) is a common side effect of BC treatment. When the lymphatic drainage system is damaged, lymphedema develops, which further exacerbates swelling and leads to pain, an increase in limb circumference, a reduction in joint range of motion, and a decrease in the use of the affected hand for functional tasks. Handgrip strength is essential for performing upper limb functional daily activities. Less is known about the long-term effects of lymphedema on hand function. The objective of the study was estimation of hand function impairment in BC survivors with lymphedema. This study was carried out by randomly selecting 100 out of 1,200 women with lymphedema, aged between 40 and 80 years, and who underwent sentinel lymph node biopsy along with radiotherapy, were included in this study. The handgrip strength was tested using an electronic handheld dynamometer. The functional wrist and hand scales were used to evaluate hand function. The Michigan Hand Outcome Questionnaire (MHQ) was used to evaluate the hand's overall function. A statistical analysis was done using SPSS statistical software (version 23.0). Handgrip strength of the affected hand by BCRL when compared with the unaffected hand was reduced. Functional hand and wrist scale have shown very poor results of the affected hand when compared with the unaffected hand. Majority of participants in the MHQ were unsatisfied with the overall functioning of the hand (p < 0.0001). This study concluded that there was significant hand function impairment in BC survivors with lymphedema. BCRL had a negative impact on daily activities of the individual and also affected the mental, emotional, and social aspects. BCRL also had an impact on overall self-reported physical function and quality of life.

It is useful to help people comprehend the incidence and risk factors for CDs in the judicial environment. To determine the prevalence of CDs among juvenile delinquents in China and explore the risk factors for CDs in terms of demographic characteristics, individual characteristics, and social environmental factors. A total of 545 male juvenile delinquents and 297 typically developed adolescents from China were recruited for this study. The Conduct Disorder Screening Form was used to assess the symptoms of CD, and related measurements, including the Demographic Questionnaire, Short-Egna Minnen av Barndoms Uppfostran for Chinese (s-EMBU-C), the Short Form of the Childhood Trauma Questionnaire (CTQ-SF), the Parental Monitoring Scale, the Deviant Peer Affiliation Scale, the Inventory of Callous-Unemotional Traits (ICU), the Self-Control Scale (SCS), and the Moral Disengagement Scale (MDS), were carried out. Among the juvenile delinquents, 58.7% met the symptoms of CD, with adolescent-onset CD accounting for 90.94% of these cases. There was no statistically significant difference in the incidence of CD between the criminal group and the illegal group, but the criminal group scored higher on aggression than the illegal group. The adolescents with CDs differed from the typically developed adolescents in demographic characteristics, parenting style, individual characteristics, and deviant peer affiliation. Discriminant analysis revealed that deviant peer affiliation had the greatest impact on the CDs of adolescents (structural matrix = 0.85), followed by the level of parental monitoring and moral disengagement. CD is widespread in Chinese juvenile delinquents. CD symptoms differ between criminal and illegal juvenile delinquents. Risk factors such as deviant peer affiliation, inadequate parental monitoring, moral disengagement, and low parental warmth all contribute to the high prevalence of CD.

Published: February 2024

Objective There is a need to undertake more proactive and in-depth analyses of general practice accreditation processes. Two areas that have been highlighted as areas of potential inconsistency are the self-assessment and surveyor assessment of indicators. Methods The data encompass 757 accreditation visits made between December 2020 and July 2022. A mixed-effect multilevel logistic regression model determined the association between attempt of the self-assessment and indicator conformity from the surveyor assessment. Furthermore, we present a contrast of the rate of indicator conformity between surveyors as an approximation of the inter-assessor consistency from the site visit. Results Two hundred and seventy-seven (37%) practices did not attempt or accurately report conformity to any indicators at the self-assessment. Association between attempting the self-assessment and the rate of indicator non-conformity at the site visit failed to reach statistical significance (OR = 0.90 [95% CI = 1.14–0.72], P = 0.28). A small number of surveyors (N = 9/34) demonstrated statistically significant differences in the rate of indicator conformity compared to the mean of all surveyors. Conclusions Attempt of the self-assessment did not predict indicator conformity at the site visit overall. Appropriate levels of consistency of indicator assessment between surveyors at the site visit were identified.

We discuss the production process of Dirac particles in a two-dimensional de Sitter geometry via the framework of rainbow gravity from the general relativity and the teleparallel theory perspectives. On this purpose, we find out the exact analytical solutions for the selected space-time model and then conclude that the general relativity and the teleparallel theory versions of the covariant Dirac equation in the

-dimensional deformed de Sitter space-time have the same exact solutions. In the subsequent step, making use of the explicit form of the Dirac spinor components and the Bogoliubov coefficients, we turn our attention to investigating the density of produced half-spin particles. Finally, we obtain two mathematical solutions for the fermionic energy spectrum.

Frequency selective surfaces (FSSs) are widely employed in spectrometers, selective absorbers, energy harvesting, and sensing devices. However, in the terahertz range, the performance of this ideal component is frequently constrained by the choice of material, which introduces a certain degree of attenuation, thereby diminishing the signal-to-noise ratio. Moreover, these FSS are often bulky and demonstrate a low extinction ratio, which limits their usage in wearables and miniaturised devices. In this work, a multi-band FSS composed of periodic microstructures on an ultrathin cyclic olefin copolymer sheet is proposed, analysed, fabricated, and evaluated using terahertz-time domain spectroscopy. The unit cell is composed of triple, evenly spaced, horizontal gold strips, linked around the middle by a fourth vertically oriented gold strip. By displacing the vertical strip, the asymmetric metasurface shows dual narrowband transmission at 1.04 THz and 1.67 THz. However, only a single narrowband transmission at 1.07 THz can be observed on a symmetric metasurface, with no displacement. The calculated Q factors are 4.52 and 16.63 at 1.04 THz and 1.67 THz, respectively, for the asymmetric metasurface. While for the symmetric metasurface, the calculated Q factor at 1.07 THz is 3.63. The proposed flexible metasurface can be tailored easily as single or dual narrowband frequency selective metasurface for channel filtering and broadband sources in emerging terahertz wireless systems.

Published: February 2024

Aerospace-sealed electronic components exhibit favourable anti-interference capability and high reliability and are widely utilised in satellites, rockets, and missiles. Loose particle detection is crucial to ensure high reliability. However, the classification problem of loose particle detection signals based on the particle impact noise detection (PIND) method has been a challenge for the high reliability of aerospace-sealed electronic components. To address this issue, this paper systematically proposes a synchronised classification method based on PIND and validates its feasibility. The proposed approach combines a self-developed empirical model (referred to as algorithm 1) with a classical machine learning model (referred to as algorithm 2). The key findings are as follows: this method has a recognition rate for loose particle signals of 91.86%. Compared to a single algorithmic mode, the overall speed improves by 300%. The maximal recognition accuracy rates for component signals, mixed signals, and excessive signals are 90.03%, 81.04%, and 95.17%, respectively. The test results demonstrate that the method effectively balances the accuracy and speed of loose particle detection and leverages the complementary advantages of the two algorithms, thereby addressing the multi-classification issue of loose particle detection signals.

Published: February 2024

Accurate online acquisition of tool wear degradation indicators is an important prerequisite for tool wear monitoring and tool remaining life prediction. The tool degradation process is usually accompanied by the flank face of cutting tool wear and blade breakage, however, the existing degradation indicators only consider the flank face wear value, but not the tool breakage value, resulting in the lack of accuracy of degradation indicators. To this end, an online identification method of tool degradation indicators based on the fusion of image sensors and laser displacement sensors is proposed, which adopts the VGG16-UNet network to identify the wear value in the image and obtains the tool breakage value based on the time series data of the laser displacement sensor. Finally, the tool wear and breakage degradation label containing wear and breakage values is established. Compared to manual measurements, the absolute average error is within 15 µms for cutter face damage values and within 3 µms for cutter face wear values.

Authors: Yan Zhiyue , Ji Jianhua , Ma Jia , Cao Wenming
Published: February 2024

Objective. This study aims to enhance medical image registration by addressing the limitations of existing approaches that rely on spatial transformations through U-Net, ConvNets, or Transformers. The objective is to develop a novel architecture that combines ConvNets, graph neural networks (GNNs), and capsule networks to improve the accuracy and efficiency of medical image registration, which can also deal with the problem of rotating registration. Approach. We propose an deep learning-based approach which can be utilized in both unsupervised and semi-supervised manners, named as HGCMorph. It leverages a hybrid framework that integrates ConvNets and GNNs to capture lower-level features, specifically short-range attention, while also utilizing capsule networks (CapsNets) to model abstract higher-level features, including entity properties such as position, size, orientation, deformation, and texture. This hybrid framework aims to provide a comprehensive representation of anatomical structures and their spatial relationships in medical images. Main results. The results demonstrate the superiority of HGCMorph over existing state-of-the-art deep learning-based methods in both qualitative and quantitative evaluations. In unsupervised training process, our model outperforms the recent SOTA method TransMorph by achieving 7%/38% increase on Dice score coefficient (DSC), and 2%/7% improvement on negative jacobian determinant for OASIS and LPBA40 datasets, respectively. Furthermore, HGCMorph achieves improved registration accuracy in semi-supervised training process. In addition, when dealing with complex 3D rotations and secondary randomly deformations, our method still achieves the best performance. We also tested our methods on lung datasets, such as Japanese Society of Radiology, Montgoermy and Shenzhen. Significance. The significance lies in its innovative design to medical image registration. HGCMorph offers a novel framework that overcomes the limitations of existing methods by efficiently capturing both local and abstract features, leading to enhanced registration accuracy, discontinuity-preserving, and pose-learning abilities. The incorporation of capsule networks introduces valuable improvements, making the proposed method a valuable contribution to the field of medical image analysis. HGCMorph not only advances the SOTA methods but also has the potential to improve various medical applications that rely on accurate image registration.

Objective. Accurate delineation of organs-at-risk (OARs) is a critical step in radiotherapy. The deep learning generated segmentations usually need to be reviewed and corrected by oncologists manually, which is time-consuming and operator-dependent. Therefore, an automated quality assurance (QA) and adaptive optimization correction strategy was proposed to identify and optimize ‘incorrect’ auto-segmentations. Approach. A total of 586 CT images and labels from nine institutions were used. The OARs included the brainstem, parotid, and mandible. The deep learning generated contours were compared with the manual ground truth delineations. In this study, we proposed a novel contour quality assurance and adaptive optimization (CQA-AO) strategy, which consists of the following three main components: (1) the contour QA module classified the deep learning generated contours as either accepted or unaccepted; (2) the unacceptable contour categories analysis module provided the potential error reasons (five unacceptable category) and locations (attention heatmaps); (3) the adaptive correction of unacceptable contours module integrate vision-language representations and utilize convex optimization algorithms to achieve adaptive correction of ‘incorrect’ contours. Main results. In the contour QA tasks, the sensitivity (accuracy, precision) of CQA-AO strategy reached 0.940 (0.945, 0.948), 0.962 (0.937, 0.913), and 0.967 (0.962, 0.957) for brainstem, parotid and mandible, respectively. The unacceptable contour category analysis, the

of CQA-AO strategy reached (0.901, 0.763, 0.862, 0.822), (0.855, 0.737, 0.837, 0.784), and (0.907, 0.762, 0.858, 0.821) for brainstem, parotid and mandible, respectively. After adaptive optimization correction, the DSC values of brainstem, parotid and mandible have been improved by 9.4%, 25.9%, and 13.5%, and Hausdorff distance values decreased by 62%, 70.6%, and 81.6%, respectively. Significance. The proposed CQA-AO strategy, which combines QA of contour and adaptive optimization correction for OARs contouring, demonstrated superior performance compare to conventional methods. This method can be implemented in the clinical contouring procedures and improve the efficiency of delineating and reviewing workflow.
