Abstract
Background Large (≥20mm) adenomatous anastomotic polyps (LAAPs) are uncommon. Data pertaining to their prevalence, characteristics, and the efficacy of endoscopic resection (ER) are absent. A safe and effective strategy for ER would reduce morbidity and healthcare costs.
Methods Large nonpedunculated colorectal polyps of ≥20mm (LNPCPs)
referred for ER were prospectively studied. Multiple data points were recorded including
anastomotic location, polyp morphology, resection modality, complications, and technical
success.
Results Over 7 years until November 2022, 2629 lesions were referred.
Of these, 10 (0.4%) were LAAPs (median size 35 mm [interquartile range (IQR) 30–40mm]). All
LAAPs were removed by piecemeal endoscopic mucosal resection (EMR), most (n=9; 90%) in
combination with cold-forceps avulsion with adjuvant snare-tip soft coagulation (CAST). On
comparison of the LAAP group with the conventional LNPCP group, CAST was more commonly used
(90% vs. 9%; P<0.001) and deep mural injury (DMI) type II was
more frequent (40% vs. 11%, P=0.003); however, significant DMI
(III–V) did not occur. At 6 month (IQR 5.25–6 months) surveillance, there was no recurrence in
any of the 10 cases. There were no serious adverse events.
Conclusions LAAPs present unique challenges owing to their location
overlying an anastomosis. Despite these challenges they can be safely and effectively managed
endoscopically without recurrence at endoscopic follow-up.

AbstractTotal glossectomy defects resulting from postoncologic resection are commonly reconstructed with locoregional or free flaps. However, effectively managing complications that may arise after reconstruction can be a significant challenge. We present a unique case series describing prosthetic management of flap-related complications following glossectomy in patients treated for locally advanced tongue cancer. Three patients underwent total glossectomy, neck dissection, reconstruction using free flap, and tracheostomy. Two patients developed an intraoral fistula located in the anterior region of the floor of the mouth. The third patient developed a flap failure requiring a second procedure using a pectoralis major myocutaneous flap for correction of the orocutaneous fistula that ultimately did not heal. Mandibular obturator prostheses lined with a soft liner were fabricated for all the patients, which helped reduce salivary incontinence and improve swallowing and speech. This case series highlights that a collaborative interdisciplinary team approach is crucial for optimizing postoperative function and outcomes when managing complications from reconstructive procedures.

Authors: Kapustina Irina , Ali Youssef , Kallen Michael E. , Hasan S. Ashfaq , Davis Derik L. 
Published: September 2023

AbstractArthroplasty-related pseudotumors are nonneoplastic and noninfectious inflammatory masses that are typically associated with adverse reaction to metal debris. Pseudotumors most commonly occur in the setting of metal-on-metal joint replacements at the hip. However, the presentation of pseudotumor at the shoulder is exceedingly rare. In this article, we reported a case of arthroplasty-related pseudotumor of the scapula. Clinical history, radiologic signs, and tissue analysis are described. Knowledge of this rare diagnosis will support clinical decision making for teams of radiologists, pathologists, oncologists, and orthopaedic surgeons who provide care for patients presenting with suspicious shoulder masses.

Published: September 2023

Abstract
Purpose: Magnetic resonance imaging (MRI) with the help of MRI-based tumor regression grade (mrTRG) score has been used as a tool to predict pathological tumor regression grade (pTRG) in patients of rectal cancer post-neoadjuvant chemoradiation. Our study aims to evaluate the ability of MRI in assessing treatment response comparing an objective mrTRG score and a subjective Likert score, with a focus on the ability to predict pathologic complete response (pCR).
Methods: Post-treatment MRI studies were retrospectively reviewed for 170 consecutive cases of histopathologically proven rectal cancer after receiving neoadjuvant chemoradiation and prior to surgery by two oncoradiologists blinded to the eventual postoperative histopathology findings. An objective (mrTRG) and a subjective Likert score were assigned to all the cases. Receiver operating characteristic curves were constructed to determine the ability of Likert scale and mrTRG to predict pCR, with postoperative histopathology being the gold standard. The optimal cutoff points on the scale of 1 to 5 were obtained for mrTRG and Likert scale with the greatest sum of sensitivity and specificity using the Youden Index.
Results: The most accurate cutoff point for the mrTRG to predict complete response was 2.5 (using Youden index), with a sensitivity of 69.2%, specificity of 69.6%, positive predictive value (PPV) of 85.6%, negative predictive value (NPV) of 46.4%, and accuracy of 69.3%. The most accurate cutoff for the Likert scale to predict complete response was 3.5, with a sensitivity of 47.5%, specificity of 89.1%, PPV of 91.9%, NPV of 39.4%, and accuracy of 59%. mrTRG had a lower cutoff and was more accurate in predicting pCR compared to Likert score.
Conclusion: An objective mrTRG was more accurate than a subjective Likert scale to predict complete response in our study.
Quantification of the Field of View for Standard Lateral Arthroscopy of the Canine Shoulder
Authors: Holman Sarah N. , Schaefer Susan L. 
Published: September 2023

Abstract
Objective The aim of this study was to define the extent of the biceps tendon, subscapularis tendon, and cranial border of the medial glenohumeral ligament within the field of view during standard lateral shoulder arthroscopy in the dog. We also examine the effect of joint flexion on the field of view of the biceps tendon.
Study Design This was a cadaveric study using 21 shoulders of large breed dogs. Each shoulder was explored with a 30-degree arthroscope using standard lateral ports. For each supporting structure, the margins within the arthroscopic field of view were marked with ink. In 11 shoulders, the distal margin of the biceps tendon was identified and marked first with the limb at a standing angle and then in flexion. The margins of the cranial border of the medial glenohumeral ligament were marked at the standing angle. In 10 additional shoulders, the margins of the subscapularis tendon were evaluated. Each joint was fully dissected and the portion of each stabilizing structure within the field of view was quantified.
Results Fifty-eight percent of the cranial border of the medial glenohumeral ligament was within the arthroscopic view. At a standing angle, 48% of the intra-articular length of the biceps tendon was within the arthroscopic view, compared to 63% with the limb flexed. Twenty percent of the subscapularis tendon was within the arthroscopic view.
Conclusion A significant portion of the biceps tendon and medial stabilizing structures of the canine shoulder are outside the field of view of arthroscopy through a standard lateral approach. The limitations of the arthroscopic field of view should be appreciated when evaluating the shoulder.
Swedish immersion in Finland and Swedish as a second-language subject in Sweden
Authors: Hedman Christina , Magnusson Ulrika 
Published: September 2023

Abstract
Based on fieldwork and interviews, we explore five teachers’ views about their teaching of Swedish as a second language in an early immersion school in Finland (Larch) and a linguistically heterogeneous primary school in Sweden (Chestnut). Drawing from ecological perspectives, we aim to contribute new knowledge on how second language teachers express their goals, teacher experiences and expertise depending on language and education policy as discursive-material reality. We discuss how societal, discursive and material differences were entangled with the teachers’ discourses, for example, the fact that Swedish immersion at Larch enjoyed a higher social status than Swedish as a second language at Chestnut. Concomitantly, the teachers adhered to pedagogical principles and the value of students’ linguistic and cultural repertoires in similar ways. We specifically discuss teacher autonomy as entwined with prevailing discursive-material realities, including distinct language education policies.

Abstract
The current study aims to compare the complaints/responses to complaints on the Facebook pages of Vodafone UK
versus Vodafone Egypt. 200 complaints and 200 responses to these complaints were collected from the Facebook pages of the two
companies in September 2022. The analysis results showed that the UK customers produced significantly more expressions of
disapproval, particularly ill consequences and annoyance, than their Egyptian counterparts. The Egyptian customers produced
significantly more blame and requests than the UK customers. In terms of responses to complaints, the UK responses were dominated
by acceptance strategies, particularly in the form of offers of repair, while the Egyptian responses came mainly in the form of
partial acceptance, particularly in the form of seeking further information.
A course of free voluntary reading on linguistic principles for average to below-average writers in university
Authors: Huck Geoffrey J. 
Published: September 2023

Abstract
This article describes an experiment in pedagogy for general writing improvement at the university level
consisting of a course of Free Voluntary Reading (FVR), which can be offered either independently of or together with standard
courses on writing. Evidence so far supporting the efficacy of FVR in helping students to improve their writing skills has largely
come from the K-12 grades and university-age foreign language students, so whether it would prove useful for university students
in general is open to question. A linguistic perspective is adopted, which entails a methodology for the experiment that differs
in major respects from that which is typical in composition studies. The results of the experiment showed that a course of FVR,
independently of instruction in writing, may be effective in improving university students’ grammatical fluency in writing.
Comment on ‘Thermodynamics of a particle in square well potential’
Authors: Fernández Francisco M 
Published: September 2023

Abstract
We argue that the approximate analytical expression for the canonical partition function for a particle in a box proposed recently was derived earlier by other authors in a more straightforward and efficient way. We also show that the canonical partition function for the particle in a finite box derived by the same authors is incorrect because they overlooked the contribution of the continuum spectrum.

Abstract
We clarify two comments made by Francisco M Fernández on our paper Bhattacharyya and Mitra (2022 Eur. J. Phys.
44 015101). The first one is regarding the calculation of the approximate partition function for a particle in a box that was derived earlier by others, and the second one is about the omission of the contribution to the continuous energy spectrum in the partition function calculation for a particle in a finite well.
Enhancing fog collection by optimizing wettability combination and fork-row collector arrangement: light and heavy fog

Published: September 2023

Abstract
Fog collection is essential to alleviate water scarcity in arid areas. However, the vast majority of existing fog collectors only work effectively in heavy fog. To broaden the fog concentration range for efficient work, an optimization strategy based on wettability combination and fork-row arrangement is proposed in this work. Single-layer experiment results show that a hydrophilic (HL) surface with high deposition capacity collects droplets at a faster rate in light fog (25–80 g h−1), while the collection rate of a hydrophobic (HB) surface with high drainage capacity is higher in heavy fog (220–500 g h−1). Double-layer experiment results show that in light fog, the best combination of double-layer collection electrodes is HL–HL, while HB–HL performs best in heavy fog. A 35% improvement in collection rate can be obtained simply by changing the arrangement from smooth-row (S) to fork-row (F), which is attributed to the increased effective collision area of droplets. In our series of experiments, at 50 g h−1, the collection rate of double-layer combination HL–HL(F) is 56.7% higher than that of single-layer HL. In particular, the collection rate of HB–HL(F) reaches 1434.7 mg cm−2 h−1 at 500 g h−1. Such a good performance is attributed to the force imbalance of hanging droplets caused by wettability differences, which tends to transport small droplets on HB towards HL directionally, resulting in a rapid droplet slippage. Therefore, the HB–HL accelerates drainage and refreshes capture points. Furthermore, fog collection performance is also influenced by layer spacing, which has an optimal distance. These findings provide a promising method for practical applications of fog collectors in a wide range of fog flow quantities, enhancing adaptability to variable environments.
Enhancing BDS-3 PPP-AR with observable-specific signal biases

Published: September 2023

Abstract
In global navigation satellite system (GNSS) data processing, precise point positioning (PPP) with ambiguity resolution (PPP-AR) is a versatile technique that aims to achieve centimetre-level accuracy by resolving integer ambiguities in carrier phase observations. However, the inherent errors and biases in the satellite signals can degrade the performance of PPP-AR solutions. To mitigate such errors, this research proposed to argument PPP-AR using third-generation BeiDou Navigation Satellite System (BDS-3) multi-frequency observations and the observable-specific signal biases (OSBs) generated at the Centre National D’Etudes Spatiales (CNES). To test the proposed technique, both BDS-3 and Galileo observations from the multi-GNSS experiment network were used, in consideration that the latter also transmits multi-frequency signals. Before demonstrating the impact of CNES bias products on PPP-AR, the quality of BDS-3 and Galileo signals was assessed. The results indicated that the modernised frequencies had the best signal strength. The mean standard deviations for the estimated OSB for different receivers were close to each other in both constellations. Besides, the positioning results in different processing schemes unveiled a comparable positioning accuracy, and slightly better in the quad-PPP strategy using the Galileo constellation in both static and kinematic modes. Galileo also attained better ambiguity fixing rates and convergence time than BDS-3. Finally, there were slight differences in the magnitude of the estimated phase residuals for distinct frequency signals between BDS-3 and Galileo, including the interoperable and compatible signals.
Effect of magnetic field on voltammetric sensor for electrolytic concentration measurement and electrode–electrolyte interface model based on a novel geometry

Published: September 2023

Abstract
Voltammetric sensor models are widely used in electrolytic applications in industry and the laboratory. Research in these domains is enriched with data analytics tools and electrode design, which need to be revised to improve the sensitivity near the Nernst limit. Therefore, an intense demand exists for enhancing the sensitivity of conventional voltammetric sensor models with minimum alteration of design parameters. This research article focuses on the possible impact of a magnetic field in a conventional voltammetric sensor for electrolytic concentration measurement. The experimental results show a 45% increase in sensitivity with a 3%–43% increment in signal attenuation due to the magnetic field. Apart from analysing the impact of a magnetic field, this research also investigates sensors with different electrode materials and input excitation. Among different electrode materials, a sensor with Iron-Niobium is found to have maximum electrolytic sensitivity of 15.78 V mol−1 l−1 while measuring the electrolytic concentration of oxalic acid in the range of 0.001–0.01 mol l−1. Similarly, the proposed voltammetric sensor with Iron-Niobium electrodes is implemented to measure the concentration of other electrolytes with 10–130 V mol−1 l−1 sensitivity to enhance applicability. A modified electrical equivalent model with an additional inductive component is also proposed in this research work that explains the waveform dip followed by a peak overshoot due to the influence of the magnetic field. The proposed electrical equivalent model of electrode–electrolyte interface is compatible with a conventional model, which is confirmed based on the experimental observations and mathematical analysis.
Attention mechanism-guided residual convolution variational autoencoder for bearing fault diagnosis under noisy environments
Authors: Yan Xiaoan , Lu Yanyu , Liu Ying , Jia Minping 
Published: September 2023

Abstract
Due to rolling bearings usually operate under fluctuating working conditions in practical engineering, the raw vibration signals generated by bearing faults have nonlinear and non-stationary characteristics. Additionally, there is a lot of noise interference in the collected bearing vibration signal, which indicates that it is difficult to extract bearing fault information and obtain a satisfactory diagnosis accuracy via using traditional method. Deep learning provides a shining road to address this issue. Nevertheless, traditional deep network model has the shortcomings of poor generalization performance and weak robustness in the feature learning. To improve fault recognition accuracy and obtain a favorable anti-noise robustness, this paper proposes a novel bearing fault diagnosis approach based on attention mechanism-guided residual convolutional variational autoencoder (AM-RCVAE). Firstly, the improved residual module is constructed to overcome the convergence difficulty problem caused by network degradation and promote the model generalization performance by replacing the batch normalization (BN) layer in the traditional residual module with the adaptive BN layer. Subsequently, by incorporating the convolutional block attention module and the improved residual module into convolutional variational autoencoder, a deep network model termed as AM-RCVAE is presented to automatically learn fault features from the original data and perform fault diagnosis tasks. The effectiveness of the proposed approach is verified via two experimental cases. Moreover, the recognition accuracy and diagnostic performance of the proposed approach have been certain improved compared with several representative methods.
Mechanical and thermodynamic properties of γ-TiAl using first-principles calculations
Authors: Alam Mahfooz , Gandi Appala Naidu 
Published: September 2023

Abstract
Temperature dependence of structural, mechanical, and thermodynamic properties of γ-TiAl is modeled using an extended quasi-harmonic approximation and first-principles calculations. In the first step, the volumes are estimated as a function of temperature following the quasi-harmonic approximation. The lattice parameters are further optimized at fixed volumes in the second step. Modeled mechanical properties (bulk modulus, shear modulus, Young’s modulus, Poisson’s ratio, and hardness) agree with the experimentally reported mechanical properties. Similarly, the modeled thermodynamic properties (entropy, heat capacity at constant pressure, Gibbs free energy) are in good agreement with the thermodynamic properties reported from experiments and CALculation of PHAse Diagrams approaches. This study suggests that further optimization of the degree of freedom in the unit cell improves the model accuracy of properties estimated following the quasi-harmonic approximation.
A shear modified GTN model based on stress degradation method for predicting ductile fracture

Published: September 2023

Abstract
The Gurson–Tvergaard–Needleman (GTN) model has provided a powerful description of the nucleation growth and coalescence of micro voids, but it has limitations in simulating shear fracture due to the absence of a description of shear localization behavior. A shear improvement method is proposed for simulating the ductile fracture of materials under different stress states. The modified model not only allows for strain hardening of the matrix material, but also accounts for the stress degradation caused by shear. The strength equation of the material is described by both the shear stress state function and a decay function, making it easier for materials under shear stress state to experience material softening and further inducing shear fracture. The modified GTN model is developed by incorporating the shear stress degradation factor into the yield function, while taking into account both void growth and shear failure mechanisms. By carefully calibrating the model’s parameters, the deformation and fracture processes of tensile, plane strain, notch tensile, and compression specimens in the 7A52 aluminum alloy are simulated. The damage evolution behavior of the material under different stress states is analyzed. The results indicate that the damage include void growth mechanism and void shear mechanism. The proportions of these two mechanisms vary under different levels of stress triaxiality. Upon localizing material deformation, the shear stress state intensifies, and the shear damage mechanism assumes a critical role in fracture. The modified GTN model accurately predicts the load-displacement response and fracture path of the 7A52 aluminum alloy under a wide range of stress states.
