Authors: Subaşı Turğut Fatma , Özçelik Ayşe Aysima , Kılıç Hasan , Karadağ Mehmet
Published: September 2024

Anti-N-Methyl-D-Aspartate receptor (NMDAR) encephalitis is recognized as the most commonly diagnosed autoimmune encephalitis and is one of the most common causes of encephalitis. A wide spectrum of symptoms such as psychosis, catatonia, behavioral and memory changes, seizures, abnormal movements and autonomic dysregulation usually requires a multidisciplinary treatment approach.Early recognition and prompt initiation of immunotherapy improves patient outcomes.We present a case of a 16-year-old female who had seizures and later had catatonia and psychotic symptoms.Our patient was treated with Rituxumab when he did not get enough benefit from the first-line treatments. Significant improvement in both neurological and psychiatric symptoms occurred after rituxumab treatment.This case highlights the importance of multidisciplinary approach in patients with NMDAR encephalitis and the importance of early transition to second-line treatments in patients who do not respond adequately to first-line treatments. It is aimed to draw attention to the fact that early diagnosis and treatment can dramatically improve neuropsychiatric symptoms, and therefore clinicians should definitely remember NMDAR encephalitis in the differential diagnosis.

Authors: Topaloğlu Mahir , Turan Zeynep , Sarıkaya Deniz , Özyemişçi Taşkıran Özden
Published: September 2024

Purpose: Gluteus medius (GMed), tensor fascia latae (TFL), and iliotibial band (ITB) play important roles in stabilizing the hip joint and are often prone to overuse syndromes such as greater trochanteric pain syndrome and runner’s knee. Shear-wave elastography (SWE) presents a new avenue for rapidly assessing these structures in an out-patient setting. This study aims to assess the intra- and interobserver reliability of sWE in evaluating the GMed, TFL, and ITB.
Materials and Methods: Twelve healthy volunteers (6 men and 6 women) were examined by two physiatrists using SWE. To assess inter-observer reliability, both physiatrists measured the thickness, velocity, and stiffness of GMed, TFL, and proximal and distal ITB. One physiatrist repeated the same measurements under identical conditions one week later to assess intra-observer reliability. Intra-class correlation coefficients (ICC) were calculated to evaluate reliability.
Results: Inter-observer measurements showed poor reliability (ICC < 0.4) for all parameters, except for GMed thickness (ICC=0.412), which was moderately reliable. Intra-observer measurements showed varying degrees of reliability, with TFL thickness (ICC=0.733), ITBP thickness (ICC=0.592), ITBD velocity (ICC=0.634), and ITBD stiffness (ICC=0.701) demonstrating moderate reliability. However, no excellent ICC scores were observed across both intra- and inter-observer assessments.
Conclusion: While SWE demonstrates promise in assessing hip stabilizers, its inconsistent reliability across different parameters highlights the need for further research. Comparative studies involving healthy and pathological groups are needed for better understanding of SWE’s applicability in clinical settings.

Authors: Özmen Yıldız Pınar
Published: September 2024

Purpose: This study aimed to investigate the relationship between left ventricular hypertrophy (LVH), assessed by echocardiographic left ventricular mass index (LVMI), and electrocardiographically evaluated R wave peak time (RWPT) and P wave peak time (PWPT) in hypertensive patients.
Materials and Methods: A cross-sectional study was conducted involving 100 hypertensive patients, excluding those with specific medical conditions. Clinical and demographic data were collected, and electrocardiographic and echocardiographic examinations were performed. RWPT and PWPT were assessed along with other parameters.
Results: LVH was present in 33 out of 100 patients. Patients with LVH exhibited significantly higher RWPT (45.6 ± 4.9 vs. 35.0 ± 5.5) and PWPT (55.5 ± 15.8 vs. 49.1 ± 12.5) compared to those without LVH. Additionally, LVH patients showed increased left atrium anteroposterior diameter, and prolonged deceleration time. QRS fragmentation was more common in the LVH group.
Conclusion: The study highlights the association between electrocardiographic parameters (RWPT and PWPT) and LVH in hypertensive patients. These findings underscore the potential utility of electrocardiogram as a non-invasive tool for LVH assessment in clinical practice in hypertensive patients, aiding in risk stratification and therapeutic decision-making.

Published: September 2024

Purpose: This paper aimed to investigate and compare diameter of the pulmonary arteries, and aorta, cross sectional area and density of the pectoralis muscles before and after COVID-19.
Materials and Methods: The axial Computed Tomography (CT) images of the chest areas of 20 individuals (12 females and 8 males) aged between 18-69 years were used. Pulmonary artery diameter (PAD), right pulmonary artery diameter (PADR), left pulmonary artery diameter (PADL), Ascending aorta diameter (AAD), the ratio of PAD to AAD, pectoralis major and minor area (PMAM) and muscle density (PMDM) before and after COVID-19 were evaluated on both healthy and COVID-19 CT images belonging to the same individuals and taken in the same year.
Results: The mean age of 20 subjects participating in the study were 48.00±11.43 years, while the mean age of 12 females was 57.80±1.64 years, and the mean age of 8 males’s was measured as 44.00±10.08 years. Also, the pectoralis major and minor area, ascending aorta diameter, left pulmonary artery diameter and right pulmonary artery diameter were higher in post-COVID 19 than pre-COVID 19. Except for the pectoralis major and minor density and truncus pulmonalis diameter, other measurements showed a decrease in patients who had COVID-19, although not significant, compared to the period before COVID-19.
Conclusion: These findings have shown that how COVID-19 affects the pulmonary artery and ascending aorta and especially the pectoralis muscles and these findings may be a sign of a change caused by COVID-19.

Authors: Tarman Kustiariyah , Supinah Pipin , Dewanti Erika Wahyu , Santoso Joko , Nurjanah Nurjanah
Published: September 2024

Carrageenan is a polysaccharide extracted from red algae and can be used as a raw material for hard-shell capsules. Carrageenan can be produced by biological hydrolysis of marine fungi. The viscosity of carrageenan resulting from hydrolysis using marine fungi is lower than that of commercial carrageenan. Gelatine can be used to modify the characteristics of polysaccharide-based materials. The characteristics and types of carrageenan and plasticizers influence the interactions between carrageenan and gelatin. This study aimed to determine the characteristics of carrageenan produced by seaweed hydrolysis of a hard-shell capsule material. The physical characteristics of the carrageenan produced by hydrolysis were determined, including yield, viscosity, and gel strength. The properties of the hard-shell capsules, including dimensions, capsule weight, disintegration time, and moisture content, were analyzed. The yield was 25%, and the viscosity and gel strength of carrageenan were 45 cP and 175 gf, respectively. Carrageenan contains 13% moisture, 8% ash, and 8% cellulose. Semi-refined carrageenan produced by this treatment was used to prepare hard-shell capsules. The capsule made from semi-refined carrageenan had a body length of 18 mm, capsule length of 10 mm, capsule weight of 0.9 grams, disintegration time of 10 min, and moisture content of 12%.
Librarian and Clinical Faculty Collaborative Use of Formative Assessment in a Longitudinal Evidence-Based Medicine Curriculum
Authors: Laws Sa'ad , Mahmoud Mai , Jabre Moune , Khidir Amal , Mahfoud Ziyad
Published: September 2024

Background
The authors developed a longitudinal curriculum for teaching third- and fourth-year undergraduate medical students evidence-based medicine (EBM). This curriculum involved substantial librarian involvement, the use of formative assessment as a teaching method, and progressive repetition of skills.
Methods
Students in three clinical clerkships (Medicine, Pediatrics, OB/GYN) completed EBM assignments based on real-world scenarios in this quasi-experimental study. Each clerkship required students to submit an EBM plan, from which they received directed feedback from both the clerkship director and a librarian after submitting preliminary EBM plans. This study tracked student PICO and search submissions to determine if repeated exposure to EBM feedback resulted in improved summative assessments, both in isolation and longitudinally.
Results
Students’ PICO and searching performance improved between mid-clerkship formative feedback and end-clerkship summative assessment in all three clerkships using rubrics developed by the authors for each clerkship derived from existing literature. When examining student performance sequentially over three clerkships, there was significant improvement between the first and second clerkships, but this did not carry into the third clerkship.
Discussion
Our findings suggest that the significant inclusion of a librarian and feedback appears to have positive effects on student performance. While it may seem obvious that feedback results in improved outcomes, this method doesn’t appear widespread in medical education. Repetition, while not having a lasting increase in performance, may still be warranted to increase exposure to authentic cases and evidence types.

ULUSAL İKTİSADİ MÜCADELENİN SİMGESİ VE ARACI: TÜRK KADINLARI (1930-1939)
Authors: Yüksel Büşra
Published: September 2024

1930’lu yıllarda Türkiye’de dış ve iç sebeplerden dolayı ortaya çıkan ekonomik kriz döneminde ülkede topyekûn mücadeleye gidilmiştir. Ülkedeki topyekûn mücadele incelendiğinde Türk kadınları, mücadelenin simgesi haline gelmiş; basın, hükümet ve toplum, kadınlara önemli sorumluluklar yüklemiştir. Çalışma, ekonomik kriz döneminde kadınların vazifelerini, kadınların tasarruf görevini ne kadar yerine getirdiklerini, ne gibi faaliyetlerde bulunduklarını, ekonomik krizde kadını ön plana çıkaran sebepleri, kadın ve tasarruf ilişkisini tespit etmeyi amaçlamaktadır. Ekonomik krizden kurtulmanın temel taşı olan tasarruf, kadın ile bütünleştirilmiş, kadın ve tasarruf başlığı, toplumun ve basının gündemini meşgul eden bir konu olmuştur.

Ekonomik savaşta kadının öne çıkarılması, erkeğin ise geri planda kalması bazı Türk kadınları tarafından tartışılmıştır. Lüksün ahlaksızlığa yol açıp açmadığı, kadınların müsrif olup olmadığı da tartışılan konular arasında yer almıştır. 1930’lu yıllarda ideal ve medeni kadın gibi kavramlar ortaya atılmış; israf etmemek, maddi ve manevi fedakârlıklar yapmak, ideal ve medeni kadın olabilmenin şartı olmuş, böylece kadınları tasarruflu olmaya özendirmeye çalışmışlardır.

Türk kadınları, iktisadi mücadeleye gönüllü olarak mı katılmışlardır? Yoksa toplum ve hükümet baskısı, kadınları bu göreve mecbur mu bırakmıştır? Ülkenin yıllarca savaş halinde olması sebebiyle fazlasıyla yıpranan Türk kadınlarının, savaş sonrası rahatlaması ve toplumsal hayatta aktif olmaları onları eğlence ve lüks hayatına özendirmiştir. Bu durum ilk başta çoğu kadını müsriflikle lekelemiş olsa da Türk kadınlarının Milli Mücadele yıllarındaki fedakârlıklarını iktisadi mücadele sırasında da görmek mümkün olmuştur.

Çalışmada, basın, meclis tutanakları ve telif eserlerden yararlanılmış, ortaya atılan tezleri kuvvetlendirmek için dönemin önemli isimleri tanık gösterilmiş, genelden özele inilerek çıkarımlarda bulunulmuş ayrıca araştırmada, sınıflandırma ve tartışma yönteminden de yararlanılmıştır.

Authors: Kuligowska Karolina , Kowalczuk Bartłomiej
Published: September 2024

Purpose of the study: This study presents an approach for improving the performance of natural language processing (NLP) models in pseudo-labeling tasks, with a particular focus on enhancing chatbot model intent recognition for business use cases. Methodology: The employed case study approach explores the pseudo-labeling technique and demonstrates a practical and efficient way to iteratively expand the original set of labeled data for the purpose of refining model training to achieve superior intent recognition accuracy in chatbots. Main Findings: The approach results in notable increases in macro-averaged F1 score and overall accuracy, particularly by iteratively re-training the model with progressively larger datasets. While enhancing the model's ability to generalize through difficult cases was effective, the study found that incorporating a full range of examples, including easy ones, yielded the best results. This comprehensive approach made the model better suited for real-world applications. Applications of the study: As chatbots are increasingly deployed in various sectors, including business, customer service, healthcare, and education, it becomes crucial for research to examine their long-term impact, scalability, and adaptability to ensure their effectiveness and sustainability in diverse contexts. Therefore, building more accurate chatbots, capable of understanding a wide range of user intents, is particularly valuable in real-world applications where chatbots need to respond to diverse, often complex and unpredictable user queries. Novelty/Originality of the study: Unlike traditional approaches, this study introduces a novel strategy of filling low-density regions in the dataset with pseudo-labels, allowing the model to better separate classes and handle semantically similar but varied messages. These advancements contribute to a more effective and scalable chatbot solution across diverse industries.
Ice Cream Sales: The Effect of Consumers, Carts, and Climate on Purchase Sizes
Authors: Srivastava Hardik
Published: September 2024

Purpose: This study focuses on the effect of consumer-base demographics, seller characteristics, and climatic factors on the sale of Ice Creams.
Methodology: Through a 6375-row dataset sourced from 15 carts and four major brands during peak Ice Cream season, the study analyses the contingencies involved in the sale of small ticket-size, seasonal retail goods.
Applications: The results can help sellers and companies better position their shops and market their products to appeal to the best-paying consumers.
Findings: We find that Women tend to buy more expensive Ice Creams than Men, high-income area residents buy more expensive Ice Creams than low-income area residents, older consumers buy more expensive Ice Creams than younger consumers, but tend to buy less frequently, and that an Ice Cream cart is better placed on a main- road than near a market. The best-paying consumer is a Woman aged 60 or more, living in a high-income area, buying from a cart located near a Main Road.
Novelty: Pre-existing literature on this topic accounts for only one or two of the several variables that we’ve chosen to select, and usually account for long time scales, causing a seasonal effect on Ice Cream sales. Our research is isolated in its approach to the comprehensiveness of consumer demographics.

Published: September 2024

In this study, biomass fly ash was investigated and determined by XRD to be predominantly langbeinite, aphthitalite, sylvine, apatite and hydroxyapatite. An alkaline leaching study was carried out on the material in a glass reactor at l/s ratio 4 temperature 600C at pH 12.85 and after drying was analyzed by ICP. The crystal structure composition of K2SO4 72.28% and potassium content of 33.47%(w/w) was recovered. The elemental transformations in this leaching process were: K 74.16%, Mg 0.55% was found to be 0.8%. It was found that a minimum of 4.84 g H2SO4 per 100 g fly ash was required to precipitate the Ca(OH)2 migrated into the liquid solution and the overall leaching efficiency was found to be 29.85%. In the alkaline leaching process, potassium was found to be easily recovered from each biomass ash. By adding 40 g H2SO4/100 g biomass waste remaining after leaching, a phosphorus recovery of 74.9% was observed. In this preliminary study, unsatisfactory results were obtained in obtaining the industry standard H3PO4. The reason for this is that the Al, Mg and K in the fly ash are subject to selective dissolution as a result of working at high pH in the alkaline leaching process.

Why Gender Matters in Violent Extremist Propaganda Strategy
Authors: Ingram Kiriloi
Published: September 2024

This policy brief presents the gender representations theoretical framework to analyse how and why gender is used in the propaganda and politico-military strategies of violent extremist movements. It argues that violent extremist ideologies break down in-group and out-group collective identities into individual “good” and “bad” gender identities, or gender representations. These representations are manipulated to maximise the effectiveness of violent extremist propaganda, and to construct a gender and conjugal order strategically designed to advance their own political objectives. The gender representations framework offers analysts a tool to examine violent extremists’ manipulation of gender to mobilise women and men, and can help in understanding the types of beliefs and actions that may be taken to advance violent extremists’ political objectives
Addressing Post-Truth in the Classroom: Towards a Critical Pedagogy
Authors: Mohammed Shan , Grundy Quinn , Bytautas Jessica
Published: September 2024

Post-truth strategies are characterized by the manipulation of facts and personal assertions of the truth for political gain. By seeding polarization, skepticism, and mistrust, post-truth presents challenges to teaching and learning within academic settings. In this paper, we explore how post-truth is articulated in higher education literature using a critical pedagogical lens. We suggest that pedagogical scholarship needs to expand its scope beyond a focus on the media antics of individual politicians in order to interrogate the reliance on dominant framings that simply define “post-truth” as circumstances where personal beliefs take precedence over established facts. We argue that the current framing of post-truth shapes the educational response to this issue, which focuses on helping students discern correct from incorrect information, as opposed to teaching students how power and knowledge are intertwined in post-truth and ways to understand and address the subsequent and potentially harmful power relations. Since post-truth strategies are enacted to restrict thoughtful reflection on dominant relations of power, we propose a critical pedagogical framework to problematize the notion of objective truth, account for the politics of exclusion, examine power relations, and contest post-truth strategies.

Advanced driver assistance systems primarily rely on visible images for information. However, in low-visibility weather conditions, such as heavy rain or fog, visible images struggle to capture road conditions accurately. In contrast, infrared (IR) images can overcome this limitation, providing reliable information regardless of external lighting. Addressing this problem, we propose an in-vehicle IR object detection system. We optimize the you only look once (YOLO) v4 object detection algorithm by replacing its original backbone with MobileNetV3, a lightweight feature extraction network, resulting in the MobileNetV3-YOLOv4 model. Furthermore, we replace traditional pre-processing methods with an Image Enhancement Conditional Generative Adversarial Network inversion algorithm to enhance the pre-processing of the input IR images. Finally, we deploy the model on the Jetson Nano, an edge device with constrained hardware resources. Our proposed method achieves an 82.7% mean Average Precision and a frame rate of 55.9 frames per second on the FLIR dataset, surpassing state-of-the-art methods. The experimental results confirm that our approach provides outstanding real-time detection performance while maintaining high precision.
Vers une augmentation structurelle de l’irrigation ? Enseignements du recensement agricole de 2020
Authors: SCOTTI Alice , LOUBIER Sébastien
Published: September 2024

L'analyse des données du recensement agricole de 2020 révèle une reprise de l'augmentation des surfaces irriguées et équipées en France métropolitaine, après une période de stagnation observée en 2010. En 2020, la surface agricole irriguée atteint 1,8 million d'hectares, représentant 6,8 % de la surface agricole utile (SAU) nationale. Cette dynamique est marquée par une forte hétérogénéité spatiale, influencée par des facteurs historiques, topographiques et pédoclimatiques. Les régions de la Nouvelle-Aquitaine, du Centre-Val de Loire et de l'Occitanie concentrent les plus grandes surfaces irriguées. L'étude met en évidence une diversification des cultures irriguées, avec une diminution relative de l'irrigation du maïs et une augmentation notable de celle de la vigne et des cultures industrielles. Ces résultats soulignent l'importance de l'irrigation comme réponse aux défis climatiques, tout en posant la question de la durabilité des pratiques actuelles.
Is Deuterium Fractionation a Major Controlling Factor in Human Metabolism and Cancer? An Essential Role for Proline
Authors: Seneff Stephanie
Published: September 2024

Deuterium is a heavy nonradioactive isotope of hydrogen, having a neutron as well as a proton, making it twice as heavy. It is a natural element, present at 156 parts per million in seawater. The ATPase pumps in the mitochondria utilize proton motive force to drive ATP synthesis, and deuterons damage the pumps, producing a stutter that can cause reactive oxygen release and inefficiencies in ATP synthesis. Cellular metabolism incorporates several novel mechanisms to assure low deuterium content in the mitochondria and other organelles. Nicotinamide adenine dinucleotide (NAD) is a major carrier of deuterium depleted (deupleted) protons to supply the mitochondria. Many enzymes, especially flavoproteins, are able to use proton tunneling to fractionate out deuterium. In this paper, we argue that the amino acid proline is able to trap and sequester deuterium, and that peptidyl prolyl isomerases (PPIases) play a central role in facilitating deuterium trapping in proline-rich proteins, most notably collagen. The endothelial glycocalyx also sequesters deuterium in gelled water lining the blood vessels, creating a battery and promoting low deuterium in the circulation. Excess deuterium promotes cancer growth, and cancer cells release large quantities of lactate via aerobic glycolysis to help reverse deuterium overload, systemically.

A novel method has been developed based on the amplitude data of the EM waves measured by Digisondes to calculate and investigate the relative ionospheric absorption changes. The effect of 13 solar flares (> C4.8) that occurred between 06:00 and 16:30 UT from 04 to 10 September 2017 have been studied at three European Digisonde stations (Juliusruh (54.63° N, 13.37° E), Průhonice (49.98° N, 14.55° E) and San Vito (40.6° N, 17.8° E)). Present study compares the results of the amplitude method with the absorption changes measured by the Finnish Riometer Network and determined by the NOAA D-RAP model during the same events. The X-class flares caused 1.5–2.5 dB attenuation at 30–32.5 MHz based on riometer data, while the absorption changes were between 10 and 15 dB in the 2.5–4.5 MHz frequency range according to the amplitude data. The impact caused by the energetic particles after the solar flares are clearly seen in the riometer data, while it can be observed only at Juliusruh (~55°) at some certain cases among the Digisonde stations. Comparing the results of the amplitude method with the D-RAP model it seems evident that the observed values exceed the values given by the model both at 2.5 MHz and at 4 MHz almost always during the investigated period. According to the comparison between the riometer data with the D-RAP, the model underestimates the values obtained from the riometers during the X-class solar flares, while it overestimates the caused impact during the particle events.

Two extruded diets isoenergetic, isonitrogenous, and isolipidic were formulated with poultry meal (CTR) as the source of animal-origin proteins (160 g/kg of feed) or with 90 g/kg of poultry meal and 70 g/kg of HFM (TRT) and were fed to eight dogs (four adult female and four adult male English Setters). Over 45 days, body weight, body condition, muscle condition, and fecal consistency scores were monitored at the beginning of the trial and after 3, 7, 15, and 45 days. No significant differences (P > 0.05) were observed for these parameters between diets and between sex. Fecal samples, collected at the same time points, were analyzed for microbiota composition. There was no significant difference in Shannon alpha diversity between the control (CTR) and experimental (TRT) diets or for diet × sampling time interaction and sex. However, beta diversity differed between diets (PERMANOVA p=0.001) and for diet × sampling interaction (p=0.009), with specific significant time points, and also differed by sex (p=0.047). LEfSe analysis showed Clostridiales, Coprococcus, Bacteroides plebeius, and others were more abundant in CTR, while Fusobacterium, Enterobacteriaceae, and others were more abundant in TRT. Temporal shifts in taxa like Prevotella copri and Fusobacterium were observed, with 25 taxa differing by sex. The study highlights diet and sex effects on gut microbiota in dogs.

Quinoa (Chenopodium quinoa, Amaranthaceae) is a pseudocereal native to the Andes of South America that contains high protein content and adequate nutrient levels. Peru possesses an abundant morphological diversity of quinoas and is among the top producers and exporters worldwide of this precious crop. However, knowledge about the genetic and population components of quinoa from the Peruvian Andes is still limited. We here used 13 microsatellite markers to determine the genetic diversity and population structure of 105 landraces of quinoa cultivated in 11 provinces of Ayacucho, the southern Peruvian Andes. A total of 285 bands were manually scored, generating a 105 x 285 presence/absence data set. Principal coordinate analysis, and similar to a dendrogram using UPGMA clustering algorithm, showed that quinoa from Ayacucho is grouped into three clusters without a clear geographic component. Estimation of the genetic diversity indices was conducted considering the three populations (C1: south 1, C2: south 2, C3: north) determined by STRUCTURE analysis, showing mean expected heterozygosity was 0.08. The highest population divergence (FST) was exhibited for C2 and C3 (0.03), whereas the lowest for C1 and C3 (0.02). Analysis of molecular variance revealed the greatest variation within populations (80.07%) and indicated that variability between populations is 19.93%. Microsatellite markers were effective; however, more studies of the genetic components of quinoa from other Peruvian Andean localities are still needed. We expect this work helps pave the way towards the development of modern breeding programs of quinoa in Peru with accurate strategies of conservation of this nutritious crop.
Doubly Fed Induction Machine Models for Integration into Grid Management Software for Improved Post Fault Response Calculation Accuracy
Authors: Mitrovic Andrija , Strezoski Luka , Loparo Kenneth A
Published: September 2024

With the escalating proliferation of wind power plants, the imperative focus on system robustness and stability intensifies. Doubly fed induction machines (DFIMs) are extensively employed as generating units in land-based wind power plants due to their performance advantages. While the stator windings of DFIMs are directly connected to the power system, the three-phase rotor windings are connected via power converters, rendering these units highly vulnerable to voltage disturbances. During faults, voltage drops at the stator terminals lead to elevated voltages and currents on the rotor side due to electromagnetic coupling between stator and rotor, potentially damaging rotor insulation and costly power electronics. Historically, to safeguard equipment, wind power plants employing distributed energy resources such as DFIMs were disconnected from the grid during faults—an unsatisfactory solution given the burgeoning number of these installations. Consequently, grid operators and IEEE standard 2800 mandate fault ride-through or low voltage ride-through capabilities to maintain supply adequacy during recovery from disturbances and voltage fluctuations. This paper provides an overview of diverse techniques devised to enable fault ride-through for DFIMs. Additionally, it scrutinizes existing approaches in modeling DFIM behavior during faults and introduces an approach tailored specifically for DFIMs, detailing its comparative advantages and limitations vis-à-vis established models. A conclusion about the necessity for more precise models in comparison to the existing ones is provided.
