Theorizing Palimpsests
Authors: Iğsız Aslı 
Published: October 2021

Abstract
How do we connect the past with the present to address structural problems? While the pursuit of a cause-and-effect past flowing into the present contributes to the understanding of an event or object, how that past is recalled, represented, related, disconnected, suppressed, and/or obfuscated in any given present matters. This article proposes palimpsests as a critical tool for analyzing the many histories of the present. To illustrate this theoretical practice, the article offers a palimpsestic reading of a museumized object, the Nubian Temple of Dendur, now at the Metropolitan Museum of Art in New York City. The structural nature of a history of the present comes into view only when one is able to discern multiple histories, presents, categories, and objects layered together within the palimpsest of history.
On Impossibility

Abstract
Should critical traditions value transparency, surface effects, and a realist attitude? Does the frame of realism help us recognize, narrate, and understand histories marked by erasure? This article analyzes Denise Riley’s 1988 book “Am I That Name?” alongside Gayatri Spivak’s essay of the same year, “Can the Subaltern Speak?” and argues that a stubbornly realist gaze remains blind to the enduring questions of feminist and postcolonial thought.
Acute complete and partial distal biceps tendon ruptures: what have we learned? A review
Authors: Caekebeke Pieter , Duerinckx Joris , van Riet Roger 
Published: October 2021

Acute distal biceps tendon (DBT) pathology includes bicipitoradial bursitis, tendinosis, partial and complete tears. Diagnosis of complete DBT tears is mainly clinical, whereas in partial tears medical imaging is a valuable addition to the clinical diagnosis. New insights in clinical and medical imaging of partial tears may reduce time to diagnosis and may guide the treatment plan. Most complete tears are best treated with primary repair using either a single-incision or double-incision approach with good clinical outcome. The double-incision technique has a higher risk of heterotopic ossification, whereas a single-incision technique carries a higher risk of nerve-related complications. Intramedullary fixation may be a viable solution to negate the risk of posterior interosseus nerve lesions in single-incision repairs. DBT endoscopy can be used to treat low-grade partial tears and tendinosis.Cite this article: EFORT Open Rev 2021;6:956-965. DOI: 10.1302/2058-5241.6.200145

In the European Union (EU), the delivery of health services is a national responsibility but there are concerted actions between member states to protect public health. Approval of pharmaceutical products is the responsibility of the European Medicines Agency, while authorising the placing on the market of medical devices is decentralised to independent ‘conformity assessment’ organisations called notified bodies. The first legal basis for an EU system of evaluating medical devices and approving their market access was the Medical Device Directive, from the 1990s. Uncertainties about clinical evidence requirements, among other reasons, led to the EU Medical Device Regulation (2017/745) that has applied since May 2021. It provides general principles for clinical investigations but few methodological details – which challenges responsible authorities to set appropriate balances between regulation and innovation, pre- and post-market studies, and clinical trials and real-world evidence. Scientific experts should advise on methods and standards for assessing and approving new high-risk devices, and safety, efficacy, and transparency of evidence should be paramount. The European Commission recently awarded a Horizon 2020 grant to a consortium led by the European Society of Cardiology and the European Federation of National Associations of Orthopaedics and Traumatology, that will review methodologies of clinical investigations, advise on study designs, and develop recommendations for aggregating clinical data from registries and other real-world sources. The CORE–MD project (Coordinating Research and Evidence for Medical Devices) will run until March 2024. Here, we describe how it may contribute to the development of regulatory science in Europe.

Aims The number of convolutional neural networks (CNN) available for fracture detection and classification is rapidly increasing. External validation of a CNN on a temporally separate (separated by time) or geographically separate (separated by location) dataset is crucial to assess generalizability of the CNN before application to clinical practice in other institutions. We aimed to answer the following questions: are current CNNs for fracture recognition externally valid?; which methods are applied for external validation (EV)?; and, what are reported performances of the EV sets compared to the internal validation (IV) sets of these CNNs? Methods The PubMed and Embase databases were systematically searched from January 2010 to October 2020 according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The type of EV, characteristics of the external dataset, and diagnostic performance characteristics on the IV and EV datasets were collected and compared. Quality assessment was conducted using a seven-item checklist based on a modified Methodologic Index for NOn-Randomized Studies instrument (MINORS). Results Out of 1,349 studies, 36 reported development of a CNN for fracture detection and/or classification. Of these, only four (11%) reported a form of EV. One study used temporal EV, one conducted both temporal and geographical EV, and two used geographical EV. When comparing the CNN’s performance on the IV set versus the EV set, the following were found: AUCs of 0.967 (IV) versus 0.975 (EV), 0.976 (IV) versus 0.985 to 0.992 (EV), 0.93 to 0.96 (IV) versus 0.80 to 0.89 (EV), and F1-scores of 0.856 to 0.863 (IV) versus 0.757 to 0.840 (EV). Conclusion The number of externally validated CNNs in orthopaedic trauma for fracture recognition is still scarce. This greatly limits the potential for transfer of these CNNs from the developing institute to another hospital to achieve similar diagnostic performance. We recommend the use of geographical EV and statements such as the Consolidated Standards of Reporting Trials–Artificial Intelligence (CONSORT-AI), the Standard Protocol Items: Recommendations for Interventional Trials–Artificial Intelligence (SPIRIT-AI) and the Transparent Reporting of a multivariable prediction model for Individual Prognosis or Diagnosis–Machine Learning (TRIPOD-ML) to critically appraise performance of CNNs and improve methodological rigor, quality of future models, and facilitate eventual implementation in clinical practice.

INTRODUCTION:
Autoimmune gastritis (AIG) is associated with nutritional deficiencies, autoimmune diseases, and gastric malignancies. The aims of the study were to test the hypothesis that mucocutaneous (MC) manifestations occur more often in patients with vs without AIG and to delineate patterns of MC manifestations in AIG.

Methods:
A single-center, prospective 2:1 case-control study was conducted. Cases were patients with the diagnosis of AIG based on consistent serologic and histologic findings. Controls had a normal gastric biopsy. MC manifestations were independently evaluated by 3 experienced dermatologists. We conducted a multivariable logistic regression model adjusted for age, sex, Helicobacter pylori, tobacco use, and alcohol consumption to estimate the association between AIG (vs no AIG) and MC manifestations (adjusted odds ratio; 95% confidence interval).

RESULTS:
We prospectively enrolled 60 cases and 30 controls (mean age 53.5 ± 15.8 vs 53.4 ± 14.5 years; 75% vs 73.3% women). The pooled prevalence of MC immune-mediated diseases was higher in patients with vs without AIG (66.7% vs 23.3%; adjusted odds ratio 12.01 [95% confidence interval: 3.51–41.13]). In patients with AIG, seropositive vs seronegative anti-intrinsic factor antibodies more often had concomitant immunological diseases with MC manifestations (100% vs 58.5%; P = 0.016). The most common MC immune-mediated diseases in AIG were Sjögren syndrome (n = 5, 8.3%), alopecia areata (n = 5, 8.3%), and vitiligo (n = 4, 6.7%). Nutritional deficiency-related MC findings, mainly xerosis, lingual, and nail disorders, were also more common in AIG.

DISCUSSION:
This is the first comparative study specifically designed to evaluate MC manifestations in AIG. We demonstrated that AIG is more frequently associated with both immune- and nutritional deficiency-related MC manifestations, which might have both diagnostic and therapeutic clinical implications.

Published: October 2021

Dialect recognition is one of the most attentive topics in the speech analysis area. Machine learning algorithms have been widely used to identify dialects. In this paper, a model that based on three different 1D Convolutional Neural Network (CNN) structures is developed for Kurdish dialect recognition. This model is evaluated, and CNN structures are compared to each other. The result shows that the proposed model has outperformed the state of the art. The model is evaluated on the experimental data that have been collected by the staff of department of computer science at the University of Halabja. Three dialects are involved in the dataset as the Kurdish language consists of three major dialects, namely Northern Kurdish (Badini variant), Central Kurdish (Sorani variant), and Hawrami. The advantage of the CNN model is not required to concern handcraft as the CNN model is featureless. According to the results, the 1 D CNN method can make predictions with an average accuracy of 95.53% on the Kurdish dialect classification. In this study, a new method is proposed to interpret the closeness of the Kurdish dialects by using a confusion matrix and a non-metric multi-dimensional visualization technique. The outcome demonstrates that it is straightforward to cluster given Kurdish dialects and linearly isolated from the neighboring dialects.

Published: October 2021

Zusammenfassung
Beim Freileitungsmonitoring wird der Durchhang der Leiterseile einer Freileitung in Echtzeit überwacht. Dadurch besteht die Möglichkeit, die Freileitungen mit höheren Strömen zu belasten. Bestehende Messsysteme für Freileitungsmonitoring liefern oft ungenaue Messwerte oder besitzen den Nachteil, dass sie direkt am Leiterseil montiert werden müssen. Damit ist eine Installation solcher Systeme nur beim Neubau möglich oder mit einer Freischaltung verbunden. Das Nachrüsten an bestehenden Freileitungen und die Wartung der Messtechnik ist daher mit hohen Kosten verbunden.
In diesem Artikel wird ein neuartiges Messsystem für Freileitungsmonitoring vorgestellt. Dieses arbeitet mit einer Kamera, welche eine Aufnahme der Leiterseile ermöglicht. Mit modernen Methoden der Bildverarbeitung wird dann deren Durchhang ermittelt. Dadurch wird eine hohe Genauigkeit erreicht, da der Durchhang direkt und nicht über Hilfsgrößen gemessen wird. Das Messsystem wird dabei am Mast und nicht an den Leiterseilen angebracht, womit sowohl Wartung als auch Installation kostengünstig durchgeführt werden können.

Objectives: The burden of valvular heart disease (VHD) is high and increasing all around the world due to aging of the population. The etiologic factors of VHD are different among countries. There is little data about etiologic factors of VHD in Iran. The aim of present study was to determine the associated factors related to the 5-year survival and mortality rate of patients undergoing bileaflet mechanical valve replacement.
Methods: In this retrospective cohort study, demographic, electrocardiographic and echocardiographic data of patients who had underwent aortic, mitral and tricuspid valve replacement with bileaflet valves in the Afshar Hospital in Yazd, Iran, between March 2008 to February 2015 were obtained from their records. Supplementary information like hemorrhagic or thromboembolic events, rehospitalization and death during follow-up were gathered through contact with patients. For analysis of the data, SPSS ver. 19 was used.
Results: Four hundred and thirty eight patients entered the study. Male gender was slightly predominant (%53). Mean age of the patients was 51.6 ± 17.4 years. The rate of in-hospital mortality was 9.8% while the 5-year survival rate was 82.42%. The rate of major thromboembolic events was 0.97%/year and that of major hemorrhagic events was 0.5%/year. Patients with older age, lower cardiac ejection fraction (less than 30%) and with atrial fibrillation had a higher rate of mortality (P = 0.001). In-hospital mortalities were 3%, 9%, 12% and 15% for AVR, AVR+MVR, MVR and CABG+valvular surgery, respectively.
Conclusions: Higher rate of mitral valve surgery in this study may be due to possible predominance of rheumatic valvular pathology similar to other developing countries. Rate of 5-year survival, thromboembolic and hemorrhagic rates were acceptable and comparable to global reports.

On March 11, 2020, the World Health Organization - WHO declared COVID-19 as a pandemic. To maintain interaction and ensure that students access quality content, teachers have started to use digital platforms. The purpose of this work is to report on the experience provided by the III Workshop of Maranhense Anatomical Techniques. The Center for Advanced Morphophysiological Studies - NEMO of the State University of the Tocantina Region of Maranhão - UEMASUL and State University of Maranhão - UEMA, held the workshop associated with the discipline of Anatomical Techniques of the Postgraduate Course in Animal Science, being one international online event through the YouTube platform. The way of teaching animal and human anatomy has evolved towards active methodologies, to accompany the didactic-pedagogical evolution with the advances in digital technology. Anatomy teachers feel the need to redefine the objectives of this discipline. The professors showed mastery over the lectures and the use of the platform used to broadcast the event, managing to talk about Animal and Human Anatomy in a completely different way, combining theory with practice. Under these circumstances, an innovative teaching-learning method, supported by the internet, has been serving an unlimited number of students interested in short courses.

Corticoperiosteal Pedicle Flap of Greater Trochanter for Salvage of Old Femoral Neck Fracture in Children
Authors: Jian Chao , Qi Baiwen , Yu Aixi 
Published: October 2021

Background:
Old femoral neck fracture (OFNF) generally refers to fractures for more than 3 weeks. Corticoperiosteal pedicle flap of greater trochanter (CPPF-GT) was designed to restore blood supply and donor bone for OFNF. This study aimed to assess the efficacy and radiographic results of CPPF-GT for treatment of OFNF in children after a minimum 5 years follow-up.

Methods:
Twenty-three patients with OFNFs, age from 8 to 16 years old, who underwent open reductions, fracture fixations, and transpositions of CPPF-GTs were retrospectively reviewed. Clinical and radiological outcomes, including union, nonunion, avascular necrosis of femoral head, limb shortening, coxa vara, premature epiphyseal closure and Ratliff’s assessment, were investigated in the postoperative follow-up. The results were compared with previously published joint-salvage study of OFNFs.

Results:
All patients were followed for an average of 5.9 years (range: 5 to 10 years). All cases (100%) achieved hip unions at an average duration of 3.5 months (range: 2.5 to 5 months). No nonunion hip was observed. Three hips (13.0%) progressed to avascular necrosis of femoral head after 1.5 to 3 years of operation, respectively, and the revision surgeries to hip replacements were conducted. Premature epiphyseal closures were observed in 3 hips. Three hips visibly presented an average 2 cm shortening of the femoral neck. Coxa vara deformities were observed in 2 hips. According to the Ratliff’s criteria, there were 20 cases (87.0%) with satisfactory union, good results were achieved in 17 cases, fair results in 3 cases, and poor result in 3 cases.

Conclusions:
Corticoperiosteal pedicle flap of greater trochanter is an effective and desirable option for treating old femoral neck fractures in children with a low rate of avascular necrosis and without nonunion.

The ichthyological collection of the Unillanos Natural History Museum (MHNU-I) is the first fish collection of the Colombian Orinoquia. The collection harbors 78 806 specimens in 3229 lots, collected between 2012 and 2019, representing 10 orders, 42 families, 170 genera, and 272 species, coming mostly from freshwater environments of the Orinoco River basin (99 %), representing 37.3 % of the total number of freshwater species listed for the Orinoco hydrographic area. The collection contains records of 20 endemic species, two threatened species (Potamotrygon orbignyi and Sorubim lima), and two introduced species (Caquetaia kraussii and Oreochromis niloticus). The information contained in this dataset allows consolidating the ichthyological collection of the MHNU, as a point of reference in terms of fish diversity of this region.

Published: October 2021

Technical reclamation and spontaneous succession (passive restoration) are the two main approaches for restoring post-mining sites worldwide. Despite substantial differences between both approaches, little is known regarding how they differ in terms of ecological outcomes. We assessed and compared the vegetation structure and composition in one spontaneous succession forest that is 29 years old, two technically reclaimed forests that are 2 and 10 years old after alluvial gold mining, and one old-growth reference forest in northeastern Antioquia, Colombia. We sampled trees and saplings establishing three Modified-Whittaker Plots in each site. We measured tree basal area, canopy cover, vegetation height, tree density, and species richness. Vegetation structure and composition differed considerably among restoration approaches. Species richness was significantly greater in the spontaneous succession forest than at the other sites. Similarly, technical reclamation significantly increased the vegetation attributes after 10 years, reaching values similar to the reference forest. We underscore the importance of fast-growth planted species (Acacia mangium, Samanea saman, and Schizolobium parahyba) to revegetate mining degraded lands.
Constructing Dual-Porosity Models from High-Resolution Discrete-Fracture Models Using Deep Neural Networks

Abstract
Detailed geological description of fractured reservoirs is typically characterized by the discrete-fracture model (DFM), in which the rock matrix and fractures are explicitly represented in the form of unstructured grids. Its high computation cost makes it infeasible for field-scale applications. Traditional flow-based and static-based methods used to upscale detailed geological DFM to reservoir simulation model suffer from, to some extent, high computation cost and low accuracy, respectively. In this paper, we present a novel deep learning-based upscaling method as an alternative to traditional methods.
This work aims to build an image-to-value model based on convolutional neural network to model the nonlinear mapping between the high-resolution image of detailed DFM as input and the upscaled reservoir simulation model as output. The reservoir simulation model (herein refers to the dual-porosity model) includes the predicted fracture-fracture transmissibility linking two adjacent grid blocks and fracture-matrix transmissibility within each coarse block. The proposed upscaling workflow comprises the train-validation samples generation, convolutional neural network training-validating process, and model evaluation. We apply a two-point flux approximation (TPFA) scheme based on embedded discrete-fracture model (EDFM) to generate the datasets. We perform trial-error analysis on the coupling training-validating process to update the ratio of train-validation samples, optimize the learning rate and the network architecture. This process is applied until the trained model obtains an accuracy above 90 % for both train-validation samples.
We then demonstrate its performance with the two-phase reference solutions obtained from the fine model in terms of water saturation profile and oil recovery versus PVI. Results show that the DL-based approach provides a good match with the reference solutions for both water saturation distribution and oil recovery curve. This work manifests the value of the DL-based method for the upscaling of detailed DFM to the dual-porosity model and can be extended to construct generalized dual-porosity, dual-permeability models or include more complex physics, such as capillary and gravity effects.
