The value of ultrasonography in predicting the outcomes of simple long bone fractures treated by closed intramedullary nail fixation

PurposeUltrasonography has been used increasingly in orthopaedic practice credited to its low cost, easy accessibility, non-invasiveness, reproducibility, and safety from radiation. The purpose of this study was to test the validity and efficacy of ultrasonography as an adjunct in the assessment of fracture healing in long bones treated with intramedullary interlocking devices and its predictive value in determining the need for a secondary surgical procedure. MethodsThis was a descriptive longitudinal study of 40 skeletally mature patients who sustained long bone fractures of the tibia or femur treated using intramedullary interlocking nails. Patients with comminuted and segmental fracture patterns were excluded from the study. Each patient was evaluated at 6- and 12-week post-surgery using standard orthogonal radiographs and ultrasonography to assess fracture healing. Patients were then followed up until fracture union. Quantitative data was analyzed using frequency statistics and descriptive data with inferential statistics. ResultsUltrasonography predicted 87.5% union and 12.5% delayed or non-union as early as 6 weeks after surgery, while radiographs predicted 22.5% union as late as 3 months of follow-up. The sensitivity and specificity of ultrasonography in assessing fracture healing were 100% and 97.2%, respectively, with a positive predictive value of 80.0%. Vascular resistance index was less than 0.5 in all patients who developed delayed or non-union. ConclusionUltrasonography is able to predict fracture outcomes much earlier than standardized radiographs with comparable sensitivity and specificity. Vascular resistance index is an objective parameter in assessing callus quality and predicting fracture outcomes.

Computational Segmentation of Timber Slabs with Free Column Placement

Modular floor slabs must be subdivided into prefabricable, transportable segments. This slab segmentation process conventionally uses a rectangular pattern, particularly for timber buildings. Regular segmentation patterns and strict column grids are ideal for rectangular building shapes, but restrict timber buildings to only some architectural uses, and are unideal for urban infill. Unfortunately, planning and constructing multi-storey wood buildings without a strict grid is still challenging. There is therefore a conflict between the desired column placement and the constraints imposed by building systems. This article investigates novel methods for segmenting timber floors supported by irregular column layouts. It proposes six different segmentation methods that are informed through Co-Design by structural, material waste, and transportation requirements. Co-Design allows for the direct integration and automated feedback of such diverse criteria into the early building design phase. These methods are based on three well-known computational approaches: Single-Objective Optimisation, Parametric Modelling, and Agent-Based Modelling. They could also be applied to other non-timber prefabricated floor systems. The segmentation methods are demonstrated on two example floor slabs with irregular column layouts, one with a rectilinear and the other with an irregular outline. The methods are compared using quantitative proxies for cost, fabrication time, architectural adaptability, and assembly complexity. More benchmark testing is needed, but initial results showed that the most efficient segmentations cannot adapt to irregular layouts, emphasising the need for a more adaptable approach to modular timber construction.

Segmented assimilation of migrant children in urban public schools of China: Impact of family resources and school segregation on their educational aspirations

Rural–urban migrant children are a rapidly growing population in Chinese cities. There is emerging literature on the educational inequality faced by migrant children, but most studies focus on their educational performance or attainments and use non-migrant children with non-agricultural hukou in urban areas as one single reference group. This paper argues that Chinese society is segmented by both hukou type and location, and examines the educational aspirations of migrant children from the perspective of segmented assimilation theory. On the basis of the 2013–2014 wave of the China Education Panel Survey, the results show a segmented assimilation pattern: migrant children with non-agricultural hukou had a similar likelihood of aspiring to tertiary education or above; whereas migrant children with agricultural hukou showed higher aspirations of completing at least tertiary education, and the disparity remained significant after considering family resources and school segregation. In family resources, social capital, in form of social communication with parents, benefited migrant children’s aspirations more than it did for their non-migrant counterparts, regardless of their hukou type. In school segregation indicators, academic segregation channeled migrant children with agricultural hukou to a less desirable condition. These findings carry practical and policy implications for understandings of migrant children’s educational aspirations.

Analysis Influence Segmentation Image on Classification Image X-raylungs with Method Convolutional Neural

The impact of image segmentation on the classification of lung X-ray images using Convolutional Neural Networks (CNNs) has been scrutinized in this study. The dataset used in this research comprises 150 lung X-ray images, distributed as 78 for training, 30 for validation, and 42 for testing. Initially, image data undergoes preprocessing to enhance image quality, employing adaptive histogram equalization to augment contrast and enhance image details. The evaluation of segmentation's influence is based on a comparison between image classification with and without the segmentation process. Segmentation involves the delineation of lung regions through techniques like thresholding, accompanied by various morphological operations such as hole filling, area opening, and labeling. The image classification process employs a CNN featuring 5 convolution layers, the Adam optimizer, and a training period of 30 epochs. The results of this study indicate that the X-ray image dataset achieved a classification accuracy of 59.52% in network testing without segmentation. In contrast, when segmentation was applied to the X-ray image dataset, the accuracy significantly improved to 73.81%. This underscores the segmentation process's ability to enhance network performance, as it simplifies the classification of segmented image patterns.

New RFI Model for Behavioral Audience Segmentation in Wi-Fi Advertising System

In this technological era, businesses tend to place advertisements via the medium of Wi-Fi advertising to expose their brands and products to the public. Wi-Fi advertising offers a platform for businesses to leverage their marketing strategies to achieve desired goals, provided they have a thorough understanding of their audience’s behaviors. This paper aims to formulate a new RFI (recency, frequency, and interest) model that is able to analyze the behavior of the audience towards the advertisement. The audience’s interest is measured based on the relationship between their total view duration on an advertisement and its corresponding overall click received. With the help of a clustering algorithm to perform the dynamic segmentation, the patterns of the audience behaviors are then being interpreted by segmenting the audience based on their engagement behaviors. In the experiments, two different Wi-Fi advertising attributes are tested to prove the new RFI model is applicable to effectively interpret the audience engagement behaviors with the proposed dynamic characteristics range table. The weak and strongly engaged behavioral characteristics of the segmented behavioral patterns of the audience, such as in a one-time audience, are interpreted successfully with the dynamic-characteristics range table.

Influence of Technological Parameters on Chip Formation and Chip Control in Precision Hard Turning of Ti-6Al-4V.

This article presents the results of an experimental investigation into the effect of process parameters in the precision hard turning of Ti-6Al-4V on chip morphology at both macro and micro levels. It also reports on the control of chip generation to improve chip evacuation and breakability at the macro level by varying the process parameters, namely, feed rate, cutting speed and depth of cut during turning tests. A scanning electron microscope (SEM) was used to examine the chips produced for a better understanding of chip curling mechanisms at the micro level. Surface roughness of the machined specimens was measured to assess the effect of chip evacuation on obtainable surface quality. From the results, it was found that the interaction of process parameters has a significant effect on the control of chip formation. In particular, the interaction of higher cutting speeds and greater depths of cut produced chip entanglement with the workpiece for all values of feed rates. Using relatively higher feed rates with a low depth of cut showed good results for chip breaking when machining at higher cutting speeds. Different chip curling mechanisms were identified from the SEM results. Chip side-curl formation showed different segmentation patterns with an approximately uniform chip thickness along the chip width, while chip up-curl occurred due to variations in chip thickness. Finally, it was found that the tangling of the chip with the workpiece has a significant effect on the final surface quality.

Significant catalyst savings and reaction kinetics enhancement for catalytic micro-combustors via non-uniform catalyst segmentation

A recent prioritization of energy-efficient and sustainable technologies has fueled an ongoing demand for improving the heat sources necessary to drive thermally dependent processes in portable and small-scale devices. Previous efforts have explored hydrocarbon-based catalytic combustion (and its kinetics and fuel usage efficiency) for reliable heating in microscale devices (TPVs, TEGs, etc.). However, for mesoscale systems that require a larger length scale combustor, fuel management and the ability to maintain consistent heat flux across the combustor become challenging due to kinetics and mass diffusion limitations, which are extrinsic to microscale combustors. In this work, we present the design and experimental evaluation of a compact parallel plate catalytic micro-combustor with non-uniform, segmented catalytic zones that allow for direct control of heating, spatially. Specifically, we performed a comparative FEM study of various catalyst segmentation patterns to further optimize catalyst bed spacing for decreased fuel consumption and improved combustion reaction kinetics. Due to these enhancements, the proposed patterning scheme can achieve similar temperature profiles to those of a fully-coated surface while using 77.8% less catalyst and reducing extreme thermal gradients during the early transient combustion phase. Finally, we demonstrated the capabilities of the proposed catalytic combustor by testing the combustor in a controlled environment.

A - 87 A Neuropsychological Case Study of Primary Progressive Apraxia of Speech Versus Agrammatic Primary Progressive Aphasia.

Primary progressive apraxia of speech (PPAOS) is a lesser-known neurodegenerative disorder characterized by progressive speech production loss, affecting word articulation. Apraxic speech commonly occurs in primary progressive aphasias (PPAs) and as a result, is often misdiagnosed as agrammatic PPA (aPPA). The current case highlights the importance of neuropsychological evaluations and behavioral observations in delineating PPAOS from aPPA. The patient is a 71-year-old right-handed White female who presented with a 2-year history of language difficulties beginning with a lisp and progressing to an inability to produce words. MRI of the brain showed moderate white matter disease. Her neurocognitive profile was notable for primary deficits in expressive language, including oral/written production, verbal fluency, and repetition. Milder deficits were observed in aspects of executive functioning. Observed spontaneous speech was notable for impaired and effortful articulation with syllabically segmented prosodic speech patterns, some distortions and prosody alterations, and slow rate. All other cognitive domains were intact. Patients with PPAOS and aPPA typically score in the impaired range on tests that depend on rate and accuracy of speech. Apraxia was her most salient feature reported and observed on testing. We did not find learning and memory difficulties, which are more common in aPPA. Moreover, she had trial-and-error articulatory attempts, groping, and distorted substitutions, which are more commonly seen in PPAOS. Her speech was also devoid of grammatical errors which is another distinguishing feature. While subtle and confounded by her alcohol use and orthopedic injuries, her profile altogether appeared most consistent with PPAOS.

Incremental segmented slope residential load pattern clustering based on three-stage curve profiles

ABSTRACT This paper tackles high computational complexity in using Euclidean distance for residential load profiles (RLPs) similarity by proposing a three-stage incremental segmented slope clustering framework. The first two stages involve static clustering, where we obtain typical residential load profiles through piecewise slope clustering. In the third stage, dynamic clustering is performed based on the slope similarity of RLPs. This method enhances clustering performance and reduces computation cost, outperforming various benchmarks, with simulation results confirming the framework's effectiveness.

ADHD and anxiety symptom comorbidity from an event segmentation lens

ADHD and anxiety present high comorbidity, including symptom overlap and related diagnostic and treatment challenges. The current study aimed to extend this area of research by investigating the event segmentation patterns of those with ADHD and anxiety symptoms. Event segmentation is the process of parsing a continuous flow of information into meaningful events, providing the opportunity to examine similarities and differences in how these groups organize their perception of daily experiences. Participants performed an event segmentation task consisting of watching four short movies and identifying large and small events. We used the total number of button presses and segmentation agreement scores in a multivariate analysis, and results indicated that the High ADHD group identified significantly more events in the large condition than the High Anxiety group and had significantly higher agreement scores than the Comorbid group. This study furthers our understanding of the cognitive overlap of ADHD and anxiety symptoms.

Dynamic segmental kinematics of the lumbar spine during diagnostic movements.

Background: In vivo measurements of segmental-level kinematics are a promising avenue for better understanding the relationship between pain and its underlying, multi-factorial basis. To date, the bulk of the reported segmental-level motion has been restricted to single plane motions. Methods: The present work implemented a novel marker set used with an optical motion capture system to non-invasively measure dynamic, 3D in vivo segmental kinematics of the lower spine in a laboratory setting. Lumbar spinal kinematics were measured for 28 subjects during 17 diagnostic movements. Results: Overall regional range of motion data and lumbar angular velocity measurement were consistent with previously published studies. Key findings from the work included measurement of differences in ascending versus descending segmental velocities during functional movements and observations of motion coupling paradigms in the lumbar spinal segments. Conclusion: The work contributes to the task of establishing a baseline of segmental lumbar movement patterns in an asymptomatic cohort, which serves as a necessary pre-requisite for identifying pathological and symptomatic deviations from the baseline.

Complex strike-slip faulting during the 2021 Mw7.4 Maduo earthquake

Fault geometry is an essential component for understanding earthquake genesis and dynamic rupture propagation. Here we employed space-based geodetic observations and geological survey, adopting a fully Bayesian approach, to probabilistically estimate the fault geometry of the 2021 Mw7.4 Maduo earthquake. The fault is predominantly characterized by strike-slip motions with three main geometry irregularities, reflecting the segmented pattern of the earthquake rupture. On the west side of the epicenter, the fault exhibits north-dipping angles (75–81°), whereas on the east side, it shows sub-vertical angles (82–87°). For the southeast branch, geodetic inversion reveals an overall shallow-dipping (44 ± 5°) faulting, yet further segmentation of the branch in the model and analysis of aftershock mechnism indicate that the dip of the branch faults may vary between vertical and shallow angles. This finding warrants confirmation through future underground observation data.These results suggest that strike-slip faulting could occur on unsuitably orientated planes during any seismic event.

A novel phase-shifting segmented phase coding method for absolute phase retrieval

The phase-coding method is widely used during 3D measurement for attaining absolute phase retrieval. However, traditional the phase-coding method still suffers from low accuracy and insufficient reliability. To address these issues, a phase-shifting segmented phase coding method was proposed in this work for absolute phase retrieval in complex object measurements, which specifically improved upon the segmented method of phase coding. Coding patterns with different phase-shifting were obtained by embedding the codeword into the phase-shifting phase. These patterns were also combined and arranged to create novel segmented coding patterns. In addition, this segmented encoding can be self-connected based on its different phase-shifting information to obtain the complete fringe order, achieving thus absolute phase retrieval of over 36 codewords. To solve the problem of the periodic misalignment of the wrapped phase and fringe order, the complementary phase coding method was encoded by the bidirectional coding method, and the separation method of the bidirectional coding was improved. From experimental results, it was demonstrated that the proposed method has high measurement accuracy and reliability.

Anatomical Variations in Pulmonary Arterial Branches in Patients Undergoing Evaluation for Chronic Thromboembolic Pulmonary Hypertension.

Catheter-based interventions have emerged for both acute and chronic pulmonary thromboembolic disease. With this development and the need for segmental cannulation, anatomic understanding of pulmonary arterial segmental branch origination is important. We aim to describe the prevalence of different pulmonary arterial segmental branch origination patterns. This study included 179 consecutive patients who underwent bilateral nonselective invasive pulmonary angiography for the evaluation of chronic thromboembolic pulmonary hypertension. In our study population (age, 59.0 ± 14.8 years, 55.3% female, 71% White), we found several anatomic variations of branches to the different lobes. These included 7 branching patterns in the right upper lobe, 3 in the right middle lobe, and 10 in the right lower lobe (4 patterns for the origin of the superior segmental artery and 6 for the origin of the basilar segmental arteries). On the left side, we found 8 patterns in the left upper lobe, with 5 involving lingular branches, and 9 in the left lower lobe (5 for the origin of the superior segmental artery and 4 for the basilar segmental pulmonary arteries). Although there were many variations, only 2-3 variations for each individual lobe accounted for >90% of the angiograms. Up to 3 anatomic branching patterns per lobe were noted to account for >90% of pulmonary artery branching variations in this study. This knowledge is not only useful for the interventionalist performing catheter-directed therapies but also for future research efforts that aim to standardize reporting of pulmonary angiographic findings.

Weight-bearing cone-beam CT with extensive coverage for volumetric imaging in adolescent idiopathic scoliosis: system implementation and initial validation.

The study aimed to introduce a novel imaging method that generates large-coverage, weight-bearing, and 3D images of the whole spine. The proposed system comprises an X-ray tube, a flat panel detector, and a standing platform. The standing platform rotates the imaged subject, allowing for the acquisition of serial fluoroscopic images from different angles which can be used to create 3D images. To increase the longitudinal coverage, we apply a segmental scanning pattern in which the imaged region is scanned in segments and stitched. To address the issue of data inaccuracy between the segments, redundant areas are set at margins of the segmental images, and registration and stitching algorithms are applied. We conducted validation experiments to evaluate radiation dose and image quality. The dose was evaluated using the volume CT dose index (CTDIvol). For image quality evaluation, we measured the low-contrast and spatial resolution. Additionally, we conducted a clinical study consisting of 30 volunteers with adolescent idiopathic scoliosis who were imaged by our method, and the images were subjectively assessed based on image noise, artifacts, anatomical coverage, diagnostic confidence, and overall quality. The CTDIvol was 1.23 mGy, and the low-contrast resolution was 0.6% at 4 mm and thespatial resolution was 8 lp/cm. The clinical images were generally of good quality, with high scores for all factors evaluated. Our method successfully generates large-coverage, weight-bearing, and 3D images of the whole spine with high image quality and low radiation dose. It shows potential for wider clinical applications for various musculoskeletal conditions.

Factor analysis of young academician consumption behaviors toward organic food and it’s obstacles

Purpose – This research aimed to explore environmentally friendly behaviors toward organic food consumption among the young academicians dominant in the higher education environment. This study also aims to explore the obstacles in consuming organic food qualitatively. Design/methodology/approach – This research uses mix methods by combining two analytical methods. The population was academicians consuming organic food in Indonesia. This research employed the purposive sampling technique. The criteria used in this study determine the sample as young academicians who are still active in higher education, care about a health issue, and regularly buy products for daily consumption, or are called regular consumers. Primary data were collected through surveys using closed and open questionnaires. The study uses mix methods consisting of descriptive qualitative and factor analysis were used in the data analysis. Findings – The results show that the factors influencing academicians' organic food consumption are responsibility for the environment, subjective norms, information or knowledge, the impact of consumption, behavioral control, and the values oriented towards nature. However, still aspects may become obstacles in consuming organic food, namely organic product price, availability, information or knowledge, and trust. Originality/value – This research offers a study of consumption from young academics, which is not widely studied, even though young academics have an important role in environmentally-friendly behavior. This research also investigated several reasons that became obstacles to the young academician behavior of consuming organic food. Research limitation – This research has several limitations, such as the variation of the sample. Cultural differences bring consequences for differences in environmentally friendly behavior because of the values that are different. Future research can compare the consumption behavior of young academicians based on the country and cultural differences. Practical implication – Based on the findings, some practical recom­men­dations for increasing environmentally friendly consumption are made through promoting organic consumption behavior's benefits and environ­mental impacts. Environmentally friendly teaching material needs to be considered part of the learning process to improve academic knowledge. Young academician can become promotional agents to shape environ­mentally friendly consumption behavior, especially organic products. Another contribution as an agent of change in behavior in the world of education is also acting as a segmentation pattern for academic groups.

O04 Segmental congenital haemangioma: a novel subtype of a rare vascular tumour

Abstract Congenital haemangiomas (CH) are rare vascular tumours present at birth. These high-flow vascular lesions can lead to significant morbidity secondary to high-output cardiac failure (HOCF) and Kasabach–Merritt phenomenon (KMP). They are classically round/oval lesions and present anywhere on the body. The majority involute spontaneously in the first 2 years of life. We describe three patients who presented with an unusual segmental pattern CH of the head/scalp: the first with a segmental CH of the left forehead, extending over the left eye with associated ipsilateral heterochromia and anisocoria; the second with a segmental ulcerated CH of the right scalp – catastrophic haemorrhage from the CH sadly resulted in death at age 6 weeks; the third with a left forehead segmental CH. None of the CH in this series developed HOCF or KMP. All lesions were consistent with CH on sonography and histology where available. Patients 1 and 3 exhibited spontaneous involution in the first 2 years of life. Segmental CH have been reported once before in a series of three patients, although involving the arm/trunk rather than the head. Two of the three patients developed KMP/HOCF. The genetic basis in this cohort was identical to that of classic nonsegmental CH, activating somatic mutations in GNAQ/11. The striking segmental pattern in our cohort is likely attributable to the timing of the somatic hit during development. Identification of this pattern in CH gives important insights into vascular tumorigenesis. Further cohort studies are needed to determine if this group has differing clinical outcomes from classical CH.

Mastigodiaptomus galapagoensis n. sp. (Crustacea: Copepoda: Diaptomidae), a possibly extinct copepod from a crater lake of the Galápagos archipelago.

A new species of a Neotropical diaptomid copepod is described based on individuals recovered from a small, almost forgotten collection of unique plankton samples from El Junco, a crater lake in San Cristóbal island, Galápagos archipelago. This copepod was regularly reported (1966-2004) as an abundant zooplankter in the lake, but it was not found in subsequent plankton surveys (2007-2018), and its specific identity remained unknown. In 2020, it was declared extinct because of introduced fish predation, rotenone treatment, and other major disturbances. The taxonomic examination of these invaluable specimens allowed us to recognize them as representing an undescribed species of the freshwater diaptomid genus Mastigodiaptomus Light, 1939. Here, we describe the new species from El Junco crater lake, located in the San Cristóbal island a part of the Galápagos archipelago, collected with plankton nets. The description is based on detailed morphology, based on SEM and light microscopy. The taxonomic examination of these invaluable specimens allowed us to recognize them as representing an undescribed species of the freshwater diaptomid genus Mastigodiaptomus Light, 1939. The new species was readily assigned to this genus and is distinguished from its known congeners by details of (1) the male right fifth leg terminal claw and aculeus, (2) spiniform processes pattern of the right geniculate antennule segments 10-16, (3) length and structure of the spiniform process of the antepenultimate segment of the male right antennule, and (4) details of the dorsal process on the female fourth pediger. This finding represents the first report of this Neotropical copepod genus outside its original biogeographic region, the third species of a diaptomid copepod reported from insular freshwater systems, the southernmost record of Mastigodiaptomus, and the only freshwater calanoid in the Galápagos. The intriguing presence of this chiefly Neotropical copepod genus here could be related either to (1) human agency linked to pirate activities, commercial travelling by Spaniard ships, whaling activities, and intense tortoise hunting in San Cristóbal island. In the past, El Junco was the only freshwater source 600 nautical miles around, or (2) zoochory of resistant dormant stages passively transported by more than 65 migrating bird species known to settle in San Cristóbal. These two hypotheses cannot be properly tested at this time, so the explanation of the presence of this copepod will remain as a new open question in the fascinating natural history of the Galápagos.

Phenotyping heart failure by echocardiography: imaging of ventricular function and haemodynamics at rest and exercise.

Traditionally, congestive heart failure (HF) was phenotyped by echocardiography or other imaging techniques according to left ventricular (LV) ejection fraction (LVEF). The more recent echocardiographic modality speckle tracking strain is complementary to LVEF, as it is more sensitive to diagnose mild systolic dysfunction. Furthermore, when LV systolic dysfunction is associated with a small, hypertrophic ventricle, EF is often normal or supernormal, whereas LV global longitudinal strain can reveal reduced contractility. In addition, segmental strain patterns may be used to identify specific cardiomyopathies, which in some cases can be treated with patient-specific medicine. In HF with preserved EF (HFpEF), a diagnostic hallmark is elevated LV filling pressure, which can be diagnosed with good accuracy by applying a set of echocardiographic parameters. Patients with HFpEF often have normal filling pressure at rest, and a non-invasive or invasive diastolic stress test may be used to identify abnormal elevation of filling pressure during exercise. The novel parameter LV work index, which incorporates afterload, is a promising tool for quantification of LV contractile function and efficiency. Another novel modality is shear wave imaging for diagnosing stiff ventricles, but clinical utility remains to be determined. In conclusion, echocardiographic imaging of cardiac function should include LV strain as a supplementary method to LVEF. Echocardiographic parameters can identify elevated LV filling pressure with good accuracy and may be applied in the diagnostic workup of patients suspected of HFpEF.

Impact of Hypocenter Location on Rupture Extent and Ground Motion: A Case Study of Southern Cascadia

AbstractThe Cascadia subduction zone has well‐documented geological records of megathrust earthquakes with the latest ∼Mw 9 rupture occurring in CE 1700. The paleoseismic observations suggest that southern Cascadia is mature for future earthquakes since the last event. Consequently, it is crucial to investigate the potential rupture scenarios. Although existing interseismic locking models share similar moment deficits, whether future earthquakes would be margin‐wide or segmented, as suggested by paleoseismic records, remains unknown. Accordingly, we aim to investigate: (a) possible rupture segmentation patterns, (b) whether south Cascadia can host margin‐wide ruptures, and (c) whether the existing locking models suggest similar future rupture scenarios. Assuming constant effective normal stress, we estimate the stress distribution constrained by the locking models (i.e., Gamma model from Schmalzle et al. (2014, https://doi.org/10.1002/2013GC005172), the preferred model from S. Li et al. (2018, https://doi.org/10.1029/2018JB015620), and the best‐fit model from Lindsey et al. (2021, https://doi.org/10.1038/s41561-021-00736-x)) from static calculation and discover they lead to different stress distributions, indicating distinct seismic potentials. Our dynamic rupture scenarios show that the south can generate both segmented ruptures (>Mw 7.3–8.4) and margin‐wide ruptures (>Mw 8.6) depending on the hypocenter location. The along‐strike rupture length appears to coincide with rupture lengths hypothesized from paleoseismology, and the Schmalzle model produces reasonable coastal subsidence amplitudes from the CE 1700 event. Therefore, we propose that three high‐slip trench‐breaching patches are sufficient for reproducing historical subsidence records. Our results can be further applied in seismic and tsunami hazard assessment, and serve as a comparison for non‐trench‐breaching scenarios.
