Background: Endometrioma is a common cause of gynecologic morbidity and the most common benign ovarian cysts are found at surgery. One of the most troubling aspects of treating endometrioma with laparoscopic excision is disease recurrence after surgery. Present study was conducted to evaluate risk factors for the recurrence of endometrioma after first laparoscopic excision. Materials and Method...

In this paper, we establish some recurrence relations for single and product moments of generalized order statistics from pth order exponential distribution. Further the results are deduced for the recurrence relations of record values and ordinary order statistics and using a recurrence relation for single moments we obtain characterization of pth order exponential distribution.

We study the existence of periodic solutions of the non–autonomous periodic Lyness’ recurrence un+2 = (an +un+1)/un, where {an}n is a cycle with positive values a,b and with positive initial conditions. It is known that for a = b = 1 all the sequences generated by this recurrence are 5–periodic. We prove that for each pair (a, b) 6= (1, 1) there are infinitely many initial conditions giving ris...

We prove new double summation hypergeometric q-series representations for several families of partitions, including those that appear in the famous product identities of Göllnitz, Gordon, and Schur. We give several different proofs for our results, using bijective partitions mappings and modular diagrams, the theory of q-difference equations and recurrences, and the theories of summation and tr...

One of the unusual variant of ovarian tumor is sex cord stromal tumor with annular tubules (SCTAT). The recurrence in case of malignant ovarian SCTAT ranges from 3mo to 20yr. This report describes the case of recurrence of SCTAT in a 35yr old woman after 4yr of hysterectomy with bilateral salphingo-Oopherectomy. Microscopic examination revealed features of SCTAT. Because of its unusual behavior...

Introduction: The recurrence rate after tympanoplasty is variable between 0% and 50%. The causes of failure may be different and frequently interrelated, making the surgical choice difficult and the prognosis not always favourable. In this study, we analysed recurrence rate and the possible causes of failure of tympanoplasty in the treatment of tympanic perforations.   Materials and Methods: Th...

We present an automatic method for mapping a system of linear recurrence equations onto systolic architectures. First, we show that systolic architectures can be derived from linear recurrence equations using the notion of directed recurrence equations. Next, we provide a procedure called CUBIZATION to achieve better performance while mapping such equations. The CUBIZATION procedure is complete...
