Most of the data on the web is in the form of natural language, but natural language is highly ambiguous, especially when it comes to the frequent occurrence of entities. The goal of ENTITY LINKING is to find ENTITY mentions and link them to their corresponding entities in an external knowledge base. Recently, FarsBase was introduced as the first Persian knowledge base with nearly 750, 000 entities. This research suggested one of the first end-to-end unsupervised ENTITY LINKING systems specifically for Persian, using context and graph-based features to rank candidate entities. To evaluate the proposed method, we used the first Persian ENTITY-LINKING dataset created by crawling social media text from some popular Telegram channels. The ParsEL results show that the F-Score of the input data set is 87. 1% and is comparable to any other ENTITY-LINKING system that supports Persian.

Background: Keratoconus is a progressive disease occurring in adolescence or early twenties. In an eye with keratoconus, the cornea thins and bulges out into an irregular cone shape. Although keratoconus may be seen in one eye, in 90% of cases, both eyes are damaged. Cross-LINKING is a novel, very chip, and rapid method to treat keratoconus. Since few studies have evaluated this method we assessed the improvement of keratoconus following cross-LINKING.Methods: This clinical trial study was performed in Feiz Hospital, Iran, during 2010-11. The target population was patients with keratoconus who were scheduled for cross-LINKING. Visual acuity was measured before and after the operation. The collected data was analyzed with SPSS20.Findings: The mean ± SD of visual acuity was -2.66 ± 2.2 before the operation and -2.8 ± 4.7 after the operation (P=0.65). While visual acuity was not changed in 29 patients (29%), it decreased in 43 cases (43%) and increased in 28 (28%).Conclusion: According to the results of this study, cross-LINKING had no acceptable effects on visual acuity in cases of keratovonus. More studies are required to clarify the efficacy of this method in improving keratovonus.

the research is derived from the master thesis of urban design, which is presented with the topic of promoting the physical ENTITY of image and landscape of Islamshahr at Shahid Rajaee University. Existing views on the quiddity of city ENTITY and its causes1are different and sometimes sporadic. Some researchers have identified ENTITY as merely conceptual meaning2hidden in the history of the city, and other researchers look for ENTITY in the integrity and continuity of physical features and the quality of the environment. The study, based on the fundamental difference between the concept of ENTITY in western philosophy and Sadra’s philosophy, attempts to prove the ENTITY of the city by considering the existential and primacy of the city ENTITY, the relationship between essence and accidents, and the prologue and the epilogue of the statement of city ENTITY. Two hypotheses, that is, the subjective and real existence of ENTITY and introducing the minor premise and major premise for the existence of the ENTITY (the prologue and the epilogue), determine the research strategy. The research method uses the qualitative -descriptive method using the theories in written documents and the logical and comparative reasoning of existing philosophical theories, including the primacy of existence, ontology, phenomenology, and substantial motion3 as a rational-philosophical inference. The results of research in the field of existential and inclusiveness of city ENTITY can be used to explain the origin of the ENTITY of city in the West and Islamic philosophy, the understanding of the relation between existence and nature to percept ENTITY. Ultimately, the assumption that the ENTITY of the city is dependent on the framework of city (like the soul that is manifested in the body) and that ENTITY with the subjective and real concept is related to human relations, will be proved. A city without ideational backgrounds is like a body without soul. And the soul can’t be presented except in the form of a body and embodiment in the cognate appearance, which evidently is the nature or quality of the city.

Introduction: Tracheocele or tracheal diverticulum is an uncommon benign ENTITY that can be congenital or acquired. It is usually diagnosed incidentally on cervicothoracic imaging. Our aim is to describe the etiopathogenic, clinical and paraclinical features of the tracheocele as well as its therapeutic modalities. Case Report: We report 2 cases of asymptomatic congenital tracheocele occurred in a boy and a woman, incidentally found on cervical CT scan done for accidental ingestion of chicken bone and infected thyroid hematocele respectively. The tracheocele, in our 2 cases, was probably congenital: no risk factors were noted and the opening of the tracheocele was narrow. The tracheocele was located in the right posterolateral tracheal wall in the 2 cases. It communicated with the tracheal lumen in one case. The female patient underwent a right lobectomy and resection of the tracheocele. For the boy, our attitude was conservative. The evolution was uneventful in the 2 cases. Conclusions: The presence or absence of risk factors, CT scan, bronchoscopy and histologic exam may distinguish between congenital and acquired forms. Asymptomatic patients are managed conservatively. Surgical resection is the treatment of choice for symptomatic patients.

A 7 years old boy presented with history of poor urinary stream, ballooning of penis during micturition and post void dribbling since birth. Physical examination revealed an enlarged penis with redundant skin on the ventral surface (Figure 1). Both corpora cavernosa were normal. Ultrasound of kidney, ureter and bladder demonstrated bilateral normal kidneys with negligible post void residual urine. . . .

Genital herpes has superseded the bacterial sexually transmitted diseases (STD) as the most prevalent STD seen worldwide, with an estimated 491 million being affected. It is encountered with an increasing frequency, with a prevalence of 11. 9% in the USA, and can present in atypical and severe ulcerative forms, especially in human immunodeficiency virus (HIV)-infected individuals. Though a definitive antiviral treatment with acyclovir, valacyclovir or other derivatives exists, the property of latency and reactivation leads to its increasing incidence and prevalence. The common sites of involvement in the males are the glans, prepuce, and shaft of the penis. The male condom, if used appropriately, is the most effective among the barrier methods of contraception, with an additional advantage of protection from STDs. However, it has a failure rate of up to 13%. The efficacy of condoms in preventing herpes simplex virus 2 (HSV-2) transmission has been studied in several contexts,condoms are often associated with a decreased risk of HSV-2 transmission, yet fallacies can occur. Here, we describe a male who developed a primary episode of genital herpes at the base of the penis, despite proper usage of condoms during intercourse. This presentation can be likened to condom chancre, a much-described ENTITY of primary syphilis.
