Annihilators of principal ideals in the exterior algebra
No full textKoç, Cemal (Dogus Author) -- Esin, Songül (Dogus Author)In this paper we describe annihilators of principal ideals of exterior algebras. For odd elements we establish formulae for dimensions of their principal ideals and their annihilators. For even elements we exhibit (multiplicative) generators for annihilator ideals

Clinical management of coronavirus disease 2019 (COVID-19) in pregnancy: recommendations of WAPM-World Association of Perinatal Medicine
No full textThese guidelines follow the mission of the World Association of Perinatal Medicine, which brings together groups and individuals throughout the world with the goal of improving outcomes of maternal, fetal and neonatal (perinatal) patients. Guidelines for auditing, evaluation, and clinical care in perinatal medicine enable physicians diagnose, treat and follow-up of COVID-19-exposed pregnant women. These guidelines are based on quality evidence in the peer review literature as well as the experience of perinatal expert throughout the world. Physicians are advised to apply these guidelines to the local realities which they face. We plan to update these guidelines as new evidence become available
Large vesicovaginal fistula in women with pelvic organ prolapse: the role of colpocleisis revisited
No full textSuccessful repair of large vesicovaginal fistulas poses a significant challenge in surgically unfit older women with pelvic organ prolapse. Two women, at ages of 85 and 93, referred for involuntary urine loss were found to have neglected pessaries resulting in large vesicovaginal fistulas. After the removal of the pessary, fistula repair and LeFort colpocleisis were done with success. At 12 months postoperatively, the patients were free of leakage and prolapse. For frail, elderly women with large vesicovaginal fistula and pelvic organ prolapse, addition of LeFort colpocleisis to the repair provides an effective treatment for both
Bone healing after biodegradable mini-plate fixation
No full textPURPOSE: To compare bone healing in mandibular vertical body osteotomies (MVBO) after fixation with a resorbable 2.0mm-profile fixation system in the first and third postoperative months in rabbits. METHODS: Twenty hemimandibles of ten rabbits were divided into two groups according to duration of resorbable fixation-one or three months. The MVBOs were performed and one four-hole, resorbable, 2.0mm mini-plate fixation system was used on each side. The computed tomography (CT) scans, scanning electron microscopy (SEM), and histomorphometric outcomes of groups I and II were compared. RESULTS: Significant differences were found between the one-and three-month assessments in terms of newly formed bone ratio values (p<0.05). There was more new bone formation at the third month on both the CT and histomorphometric examinations. A better adaptation of the bone tissues to the resorbable mini-plate and screws was observed on SEM at three months. CONCLUSION: The resorbable mini-plates provided a fixation stable enough to allow immediate oral alimentation and callus formation in both groups
Analysis of nonlinear compartmental model using a reliable method
No full textThe goal of this work is to investigate nonlinear models and their complexity using techniques that are universal and have connections to historical and material aspects. Using the premise of a constant population that is uniformly mixed, a nonlinear compartmental model that depicts the movement between voter classes is taken into consideration. In the current work, we investigate the dynamical framework that supports the interactions between the three parties. It is discussed how rate change affects various metrics. The conditions for boundedness, stability, existence, and other dynamics are obtained. We derive the effects of generalizing the model in any order. The current study supports investigations into complex real-world issues and forecasts of necessary plans. © 2023 The Author(s
A Novel Study of Morlet Neural Networks to Solve the Nonlinear HIV İnfection System of Latently İnfected Cells
No full textThe aim of this study is to provide the numerical outcomes of a nonlinear HIV infection system of latently infected CD4+ T cells exists in bioinformatics using Morlet wavelet (MW) artificial neural networks (ANNs) optimized initially with global search of genetic algorithms (GAs) hybridized for speedy local search of sequential quadratic programming (SQP), i.e., MW-ANN-GA-SQP. The design of an error function is presented by designing the MW-ANN models for the differential equations along with the initial conditions that represent the HIV infection system involving latently infected CD4+ T cells. The precision and persistence of the presented approach MW-ANN-GA-SQP are recognized through comparative studies from the results of the Runge-Kutta numerical scheme for solving the HIV infection spread system in case of single and multiple trails of the MW-ANN-GA-SQP. Statistical estimates with ‘Theil's inequality coefficient’ and ‘root mean square error’ based indices further validate the sustainability and applicability of proposed MW-ANN-GA-SQP solver. © 2021 The Author
