A semantic rule based digital fraud detection

Digital fraud has immensely affected ordinary consumers and the finance industry. Our dependence on internet banking has made digital fraud a substantial problem. Financial institutions across the globe are trying to improve their digital fraud detection and deterrence capabilities. Fraud detection is a reactive process, and it usually incurs a cost to save the system from an ongoing malicious activity. Fraud deterrence is the capability of a system to withstand any fraudulent attempts. Fraud deterrence is a challenging task and researchers across the globe are proposing new solutions to improve deterrence capabilities. In this work, we focus on the very important problem of fraud deterrence. Our proposed work uses an Intimation Rule Based (IRB) alert generation algorithm. These IRB alerts are classified based on severity levels. Our proposed solution uses a richer domain knowledge base and rule-based reasoning. In this work, we propose an ontology-based financial fraud detection and deterrence model.

Vasoproliferative retinal tumors. Current approach to treatment

Relevance. Vasoproliferative retinal tumor is a rare acquired disease. The exact pathogenesis of vasoproliferative tumors remains completely unknown, and it has long been assumed that their development is a reactive process with the proliferation of glial cells and blood vessels. Despite the widespread use of this term, vasoproliferative tumor cannot be fully attributed to true tumors and it cannot be reliably established that it is vascular in its pathogenesis. The clinical signs of vasoproliferative retinal tumor manifests itself as a yellowish-red, often loose mass with vessels of normal or slightly enlarged caliber, usually small, single and located in the lower-outer or lower part of the fundus. Due to their rarity, there are currently no uniform recommendations for the diagnosis and treatment of this pathology. Most of the available methods have limited effectiveness, causing a temporary regression of the process, which makes it necessary to repeatedly re-treat or combine several treatments. In some cases, the use of several therapeutic options leads to complications that can be caused by both therapy and the natural progression of the disease, which together prevents reconvalescence and improvement of visual func tions. Purpose. This article presents for the first time a detailed review of the literature, including generalized data on the epidemiology, pathogenesis, histological features, differential diagnosis and modern approaches to the treatment of this pathology. Material and methods. The article uses literary materials of domestic and foreign authors published in the period from 1982 to the present. Conclusion. It is necessary to further study the mechanisms of development of vasoproliferative tumors and related complications. The article uses literary materials of domestic and foreign authors published in the period from 1982 to the present. Keywords: vasoproliferative tumors, retinal vascular tumors, retinal angiomatosis, endoresection, vitrectomy, brachytherapy.

A Novel Therapeutic Approach for Cranial Fasciitis Utilizing Frameless Stereotaxy

Cranial fasciitis is a rare cause of a painless, progressive skull mass in the pediatric population, having been described in only 80 cases in the literature to-date. While the etiology remains unknown, the pathogenesis is thought to be a reactive process causing a non-neoplastic fibroblastic proliferation arising from the deep fascia or periosteum of the cranium. Accurate diagnosis may be delayed due to the lack of physical signs and symptoms on presentation, as well as equivocal imaging for the other lesions included in the differential diagnosis. Importantly, in the case of cranial fasciitis, involved tissue is hard to decipher from normal tissue in the cranium, and margin recommendations have not yet been made clear in the current literature. Herein, we present a case of confirmed cranial fasciitis in a 2-year-old female patient in whom frameless stereotaxy was used intraoperatively to determine the extent of the lesion and ensure adequate resection and minimize recurrence risk.

CD30-positive T-cell lymphoproliferation of the bulbar conjuntival mucosa showing spontaneous remission

Introduction: CD30-positive T-cell lymphoproliferative lesions represent a spectrum of heterogeneous disorders. Clinical case: An incision biopsy was performed in a 25-year-old man with a lump in the bulbar conjunctiva. Immunohistochemistry indicated membrane positivity for CD3 and CD30 in over 75%. PCR identified the monoclonal nature of the T-cells. The hematological study was normal. Following biopsy, the conjunctival tumor diminished until disappear. Conclusions: Mucosal CD30-positive T-cell lymphoproliferation could be ascribed to a reactive process but it is necessary to rule out a primary conjunctival tumor or the first manifestation of an anaplastic large cell lymphoma.

An ultrafast process for the fabrication of a Li metal–inorganic solid electrolyte interface

A strategy to use a reactive process using ultrasonication has been suggested for the ultrafast fabrication of Li metal–inorganic solid electrolyte interface.

Peripheral Ossifying Fibroma: A Case Report

Peripheral ossifying fibroma (POF) is a common solitary gingival growth thought to arise from the periodontal ligament. Though the etiology of POF remains unknown, some investigators consider it an inflammatory or reactive process, while others suggest it is a neoplastic process. Here, we present a case of POF in a 10-year-old boy, affecting the maxillary anterior gingiva along with its clinical, radiographic, histologic characteristics, differential diagnosis, treatment and one year follow-up.
