uterine sarcoma is a rare tumor of mesodermal origin, accounting for 2-6% of uterine malignancies. leiomyosarcoma (lms) has been reported in only 1% of all uterine malignancies and is regarded as the most common primary uterine sarcoma. herein, we present a case of lms with unusual macroscopic features. the patient was a 61-year-old woman with lms, which consisted of a large cystic mass (88×136...

For a new kind of automatic transmissions using proportional pressure valves to control the clutches directly, a two-degree-of-freedom controller is designed for clutch slip control during the inertia phase of the shift process. The controller is designed based on a low order linear model which is derived from dynamics of the proportional pressure control valve and the vehicle drive line. The f...

Least mean square (LMS) type adaptive algorithms have attracted much attention due to their low computational complexity. In the scenarios of sparse channel estimation, zero-attracting LMS (ZA-LMS), reweighted ZA-LMS (RZA-LMS) and reweighted -norm LMS (RL1-LMS) have been proposed to exploit channel sparsity. However, these proposed algorithms may hard to make tradeoff between convergence speed ...

  Background and Objectives: Uterine smooth muscle tumors are the most common human neoplasm .They are divided clinically as benign and malignant but there is  another group of  lesions which is difficult to place in these two categories ,so-called smooth  muscle tumors of uncertain malignant potential (STUMP) and differentiation  of these tumors on the basis of H&E staining is impossible . Th...
