Prescribed‐time resilient current‐sensorless DC power converter control
Authors: Homayounzadeh Maryam , Homayounzade Mohamadreza , Khooban Mohammad‐Hassan 
Published: October 2024

AbstractWhile conventional control techniques for stabilizing power electronic converters with constant‐power load (CPL) often rely on complete system state information, the associated challenges, including the cost and increased size due to the installation of multiple sensors, necessitate exploration of alternative methodologies. To address these concerns, a novel observer‐based sliding‐mode control approach is proposed. This approach aims to enhance cost‐effectiveness and reliability in the context of a DC‐DC buck converter supplying power to an unknown CPL. The core concept involves designing a state observer to estimate the system's current based on voltage measurements. A non‐certainty equivalent adaptive update law is then introduced to estimate the unknown CPL, incorporating feedback from voltage measurements and current estimation. To guarantee stability in the face of uncertainties in system parameters, a thorough analysis utilizing the Lyapunov theorem is conducted on the closed‐loop system. The efficacy and feasibility of the proposed control algorithm are substantiated through experimental results on the OPAL‐RT platform, showcasing its promising performance.
Quasi‐Z‐source interleaved DC‐DC converter for fuel cell vehicle application

Published: October 2024

AbstractIn this study, a step‐up DC‐DC converter with a combination of a two‐phase interleaved structure and a quasi‐Z impedance network is proposed for fuel cell vehicle application. The operation of the converter in a small duty cycle (0 < D < 0.5) reduces the conductive losses of the switches and as a result increases the efficiency of this converter compared to conventional boost converters. Also, due to the common ground between the input and output, unlike the floating interleaved boost converter (FIBC) and the parallel input‐series output converter (PISO), it does not face the problem of imposing additional EMI on the converter circuit. This converter has a low input current ripple, suitable voltage gain for fuel cell vehicles system, as well as high reliability due to the ability to operate with one phase in case of failure in the other phase. It can be a suitable candidate for practical application in fuel cell vehicles. The principles of operation and the main characteristics of the converter such as voltage gain, input current ripple, and voltage and current stress of the elements are explained and also a 120‐W experimental prototype with 12‐V input voltage and 60‐V output voltage is made to validate the theoretical analysis results.

Diarrhea caused by zoonotic pathogens is one of the most common diseases in dairy calves, threatening the health of young animals. Humans are also at risk, in particular children. To explore the pathogens causing diarrhea in dairy calves, the present study applied PCR-based sequencing tools to investigate the occurrence and molecular characteristics of three parasites (Cryptosporidium spp., Giardia duodenalis, and Enterocytozoon bieneusi) and three bacterial pathogens (Escherichia coli, Clostridium perfringens, and Salmonella spp.) in 343 fecal samples of diarrheic dairy calves from five farms in Lingwu County, Ningxia Hui Autonomous Region, China. The total positive rate of these pathogens in diarrheic dairy calves was 91.0% (312/343; 95% CI, 87.9–94.0), with C. perfringens (61.5%, 211/343; 95% CI, 56.3–66.7) being the dominant one. Co-infection with two to five pathogens was found in 67.3% (231/343; 95% CI, 62.4–72.3) of investigated samples. There were significant differences (p < 0.05) in the positive rates of Cryptosporidium spp. and diarrheagenic E. coli among farms, age groups, and seasons. Two Cryptosporidium species (C. parvum and C. bovis) and five gp60 subtypes of C. parvum (IIdA15G1, IIdA20G1, IIdA19G1, IIdA14G1, and a novel IIdA13G1) were identified. Two assemblages (assemblage E and zoonotic assemblage A) of G. duodenalis and six ITS genotypes of E. bieneusi (J, Henan-IV, EbpC, I, EbpA, and ESH-01) were observed. Four virulence genes (eaeA, stx1, stx2, and st) of diarrheagenic E. coli and one toxin type (type A) of C. perfringens were detected. Our study enriches our knowledge on the characteristics and zoonotic potential of diarrhea-related pathogens in dairy calves.

Published: October 2024

ZusammenfassungDie infektiöse Endokarditis (IE) ist eine seltene, aber potenziell lebensbedrohliche Erkrankung, die durch eine Infektion verursacht wird. Obwohl sie selten ist, kann sie schwerwiegende Komplikationen wie Herzklappeninsuffizienz oder septische Embolien nach sich ziehen. Im Jahr 2019 betrug die geschätzte Inzidenz der IE 13,8 Fälle pro 100000 Probanden pro Jahr und verursachte weltweit über 66000 Todesfälle. Die Endokarditisprophylaxe als Vorbeugung gegen diese Erkrankung ist von entscheidender Bedeutung, insbesondere für Personen mit bestimmten Risikofaktoren. Seit der Veröffentlichung der ESC-Leitlinien für die Behandlung der IE 2015 wurden wichtige neue Daten veröffentlicht, die eine Aktualisierung der Empfehlungen erforderten. In diesem Artikel werden die aktuellen Empfehlungen zur Endokarditisprophylaxe gemäß den ESC-Leitlinien 2023 erläutert.

Published: October 2024

AbstractThe aim of the study was to describe the preventive option and safety of laparoscopic transabdominal emergency cerclage in pregnant women with advanced cervical shortening after failed vaginal cerclage or in whom vaginal cerclage is no longer possible.Laparoscopic isthmo-cervical emergency cerclage was carried out in two patients at 13+0 and 15+5 weeks of gestation (GW) respectively. Both patients had cervical shortening and it was no longer possible to expose the cervix after conization or re-conization. The attempts to carry out transvaginal cerclage were unsuccessful. The technical aspects, feasibility, safety, and pregnancy outcomes after laparoscopic transabdominal cerclage are presented here, based on two case reports.The cerclages were placed after blunt dissection of the uterine vessels and careful introduction of a KELLY forceps through the avascular space between the ascending and descending branches of the uterine vessels without using a needle. The operating times were 93 and 134 minutes (min), respectively. The estimated blood loss during the procedure was less than 50 ml and neither perioperative nor postoperative complications occurred. The subsequent course of both pregnancies was uneventful and fetal development in both cases was normal. In the first case, the baby was delivered by secondary cesarean section following premature rupture of membranes in week 35+4 of gestation. The baby had a birthweight of 2786 g, APGAR scores of 8/9/10 and an umbilical cord arterial pH of 7.36. In the second case, delivery was by primary cesarean section in week 39+5 of gestation. The infant had a birth weight of 4160 g, APGAR scores of 5/9/10 and an umbilical cord arterial pH of 7.20.Laparoscopic transabdominal cerclage is a safe and effective treatment option, even early in the second trimester of pregnancy, for patients in whom transvaginal cerclage is no longer possible due to anatomical factors. The method is technically very feasible and is associated with positive obstetric outcomes. The overall risk of perioperative complications is within acceptable limits.
Structural Requirements for the Outpatient Treatment of Benign Diseases of the Uterus
Authors: Brucker Cosima , Dimpfl Thomas , Scharl Anton 
Published: October 2024

AbstractIn many cases, outpatient surgical treatment of benign diseases of the uterus has advantages over inpatient care. This has been demonstrated by the healthcare situation in other countries. However, the prerequisite for the provision of outpatient services is that this does not lead to any impairment in the quality of care or of patient safety. The ultimate goal should not be to reduce costs but rather to maintain and, ideally, improve the quality of care. This requires that services are not just defined by the surgical procedure but also by the entire treatment chain, including, for example, psychosocial support, and are remunerated accordingly. It is particularly worrying that the final decision as to whether an outpatient operation is possible is not the responsibility of the operating unit, but of the “Medizinischer Dienst,” with the corresponding options and threats of sanctions. This situation is unique internationally and requires a paradigm shift. Furthermore,
structural prerequisites must be maintained which currently only exist inadequately in Germany. Since a substantial proportion of planned outpatient operations require immediate or secondary inpatient treatment, there must be a barrier-free transition between the outpatient and inpatient sectors. This will require the creation of networks between outpatient service providers and one or more hospitals that are equipped and competent to manage even complex complications. It is important to create structures that, with intensive involvement of the operating unit, include adequate preoperative evaluation and patient education as well as needs-oriented postoperative care at home. The current separation of sectors is a significant hinderance. Moreover, when expanding and promoting outpatient surgery, the aspect of training and further education of specialist staff must be taken into account, as well as cross-sectoral quality assurance.Based on a review of the international literature, this article presents 13 recommendations for adequate structures when providing outpatient services which should serve as a prerequisite for the greatest possible guarantee of patient safety.

Abstract
Objective The incidence of seizures is highest in the elderly, and their management is challenging in view of atypical presentation and comorbidities. The aims of this analysis were to study the classification, etiology, and risk factors in new onset seizures in the elderly (>60 years) and their impact on the quality of life (QOL) and caregiver burden.
Materials and Methods All the elderly presenting to neurology, neurosurgery and emergency medicine OPD with new onset seizures after the age of 60 years were included. QOL and caregiver burden were assessed at least 6 months after the first seizure. The QOL was assessed with the World Health Organization Quality of Life OLD (WHOQOL-OLD) and was compared with age-matched controls. Caregiver burden was assessed with the Zarit Burden Interview.
Result Eighty patients fulfilling the inclusion criteria and 80 age-matched controls were recruited. There was no difference in age (68.30 ± 6.22 vs. 69.09 ± 6.07 years; p = 0.39) and gender (M:F = 50:30 vs. 48:32; p = 0.74) among the cases and controls. Forty-four (55%) patients had focal seizure. Hypertension was the commonest risk factor (61.3%), followed by ethanol intake (40%) and diabetes (38.8%). Cerebrovascular disease was the commonest etiology (37.5%), followed by infection (15%). Thirteen (16.2%) patients died during hospital stay and 20 (25%) died after discharge from the hospital. Cases scored significantly low on all domains of WHOQOL-OLD at 6 months of follow-up. In all, 54.1% caregivers reported mild to moderate burden.
Conclusion Focal seizure is the commonest seizure type of new onset seizure in the elderly. Hypertension is the commonest risk factor and cerebrovascular disease is the commonest etiology. New onset seizures in the elderly have a significant impact on both QOL and caregiver burden.
Delayed Maxillary Reconstruction with Free Osteocutaneous Fibula Flap Using CAD-CAM Technology
Authors: Krishnappa Madhusudhan , Gaba Sunil , Sharma Shagun , Sharma Shubham , Ahuja Chirag K. , Kalra Parveen 
Published: October 2024

Abstract
Background Maxillary reconstruction poses unique challenges for the reconstructive surgeon because of the complex three-dimensional (3D) anatomy of the maxilla. Undertaking this endeavor on secondary reconstruction makes it more difficult due to problems in recreating the true defect. This study is an attempt to demonstrate the role of virtual surgical planning (VSP), 3D printing, and mock surgery in reconstructing such defects using free fibula flaps.
Materials and Methods This was a prospective study involving 10 patients of maxillary defects who underwent delayed reconstruction with a free fibula flap. The planning was done preoperatively using computer-aided design and computer-aided manufacturing (CAD-CAM) technology. A mock surgery with 3D printed models was done before the surgery. After the surgery, the accuracy results were obtained by overlapping and measuring fixed point distances between preoperative virtual planning and postoperative computed tomography (CT) scan data.
Results and Discussion Nine patients underwent successful reconstruction and were satisfied with the outcome. One patient had flap loss. The mean shift along the horizontal, vertical, and 3D axes was less than 5 mm between the preoperative virtual planning and postoperative CT scan data, indicating accurate reconstruction. We also suggest strategies for soft-tissue and bony inset including inferolateral pedicle origin, anteriorly facing lateral fibular surface, and two bony struts for the alveolus.
Conclusion VSP and CAD-CAM technology in maxillary reconstructions help achieve an anatomically accurate neo-maxilla. The addition of mock surgery to the routine and the use of cutting guide avoid unpredictability and reduce the need for adaptation activities on the operating table. CAD-CAM technology despite its limitations is invaluable in maxillary reconstruction and is an important tool for a reconstructive plastic surgeon.
Thermomechanical-chemical devulcanization of ground tire rubber
Authors: Görbe Á , Kohári A , Halász-Kutasi I Z , Bárány T 
Published: October 2024

Abstract
We developed a thermomechanical devulcanization process of ground tire rubber (GTR) by incorporating chemicals to achieve better devulcanization. The samples were devulcanized in a twin-screw extruder with the help of three types of chemicals that aid devulcanization: N-(cyclohexylthio) phthalimide (PVI), dibenzamid diphenyl disulfide (DBD) and dialkyl-pentasulfide (DPS, commercialized as Aktiplast 79). We characterized the resulting devulcanizates by Soxhlet-extraction, and produced vulcanized sheets, which we characterized mechanically and examined the vulcanization process. We found that all chemicals facilitated better devulcanization and the devulcanizate had a more rubber-like behavior during mixing. Vulcanization was also slightly improved and reversion was reduced. When revulcanized, the rubber had improved strain at break and tear strength.
Improving the bonding technology of aluminium sheet used in the construction industry by gas flame surface treatment
Authors: Tajti F , Capár A 
Published: October 2024

Abstract
According to current building trends, aluminium sheets can be used as building cladding elements. The advantage is that aluminium has a low density but high strength and resistance to atmospheric corrosion. For a nice appearance, these sheets are coloured with a polyester-based powder coating and are fixed by adhesive bonding on the reverse side. For adhesion, a flexible adhesive is required, and it should be noted that the surface is painted. From a safety point of view, it is important that the strength of the bonded joint does not deteriorate over many years. In our research, we investigate the applicability of gas flame surface treatment technologies to improve the bonding technology of aluminium sheets coated with polyester-based paints. The effectiveness of the surface treatment is tested by surface wettability measurements and, based on the results obtained, test joints are made to test their tensile and shear strength.
Cold plasma irradiation inhibits skin cancer via ferroptosis

Published: October 2024

Abstract
Cold atmospheric plasma (CAP) has been extensively utilized in medical treatment, particularly in cancer therapy. However, the underlying mechanism of CAP in skin cancer treatment remains elusive. In this study, we established a skin cancer model using CAP treatment in vitro. Also, we established the Xenograft experiment model in vivo. The results demonstrated that treatment with CAP induced ferroptosis, resulting in a significant reduction in the viability, migration, and invasive capacities of A431 squamous cell carcinoma, a type of skin cancer. Mechanistically, the significant production of reactive oxygen species (ROS) by CAP induces DNA damage, which then activates Ataxia-telangiectasia mutated (ATM) and p53 through acetylation, while simultaneously suppressing the expression of Solute Carrier Family 7 Member 11 (SLC7A11). Consequently, this cascade led to the down-regulation of intracellular Glutathione peroxidase 4 (GPX4), ultimately resulting in ferroptosis. CAP exhibits a favorable impact on skin cancer treatment, suggesting its potential medical application in skin cancer therapy.

Abstract

Background. ThePlease provide an email address for the corresponding author. risk of biochemical recurrence (BCR) after radiotherapy for localized prostate cancer (PCa) varies widely within standard risk groups. There's a need for low-cost tools to more robustly predict recurrence and personalize therapy. Radiomic features from pretreatment MRI show potential as noninvasive biomarkers for BCR prediction. Previous research has not fully combined radiomics with clinical and pathological data in predicting BCR of PCa patients after radiotherapy. Purpose. This study aims to predict 5-year BCR using radiomics from pretreatment T2W MRI and clinical-pathological data in PCa patients treated with radiation therapy, and to develop a unified model compatible with 1.5T and 3T MRI scanners. Methods. 150 T2W scans and clinical parameters were preprocessed. 120 cases were used for training and validation, and 30 for testing. Four distinct machine learning models were developed: Model 1 used radiomics, Model 2 used clinical and pathological data, Model 3 combined these via late fusion. Model 4 integrated radiomic and clinical-pathological data via early fusion . Results. Model 1 achieved an AUC of 0.73, while Model 2 had an AUC of 0.64 for predicting outcomes in 30 new test cases. Model 3, using late fusion, had an AUC of 0.69. Early fusion models showed promise: Model 4 reached an AUC of 0.84 highlighting the effectiveness of early fusion model. Conclusions. This study is the first to use fusion technique for predicting BCR in PCa patients following radiotherapy, using pre-treatment T2W MRI images and clinical-pathological data. Our methodology improves predictive accuracy by fusing radiomics with clinical-pathological information, even with a small dataset, and introduces the first unified model for both 1.5T and 3T MRI images.
The Possibility of Perceptual Knowledge
Authors: Stroud Barry 
Published: October 2024

Abstract
Stroud identifies two obstacles that stand in the way of a satisfactory understanding of perceptual knowledge: an overly restrictive conception of what we can perceive and an overly intellectualized conception of knowledge. He traces these obstacles to a broadly Cartesian approach to perceptual knowledge that focusses on individual “perceptual experiences”. Stroud develops an alternative approach by putting centre stage not “experiences” and their phenomenal properties, but the perceiver or knower as a competent intentional agent, and by describing the capacities that someone must possess and exercise in order to know something by perceptual means.
Perception, Knowledge, and Reflection
Authors: Roessler Johannes 
Published: October 2024

Abstract
Some philosophers take it that understanding human self-knowledge must be a matter of giving an account of how we discover the relevant facts about ourselves. Others maintain that rational thinkers have no need for any way of finding out (e.g.) what they believe or what they are intentionally doing: self-knowledge in these cases is thought to flow from the successful exercise of the relevant first-order capacities (capacities to believe, or act, for reasons). This chapter aims to develop the second tradition in a way that broadens its traditional remit, which has been restricted to attitudes or actions for which reasons can intelligibly be asked. It is argued that if a rational perceiver can see that p she will typically be aware that she can see that p, in virtue of exercising relevant capacities for perceptual recognition. Such capacities, it is suggested, are potentially reflective in the following sense: we paradigmatically exercise them in making perceptual judgements, underwritten by an implicit awareness of how we know what we judge to be the case.
