A method of collision avoidance for point mass UAVs (own and intruder) with constant velocity is described in 3-D. This paper discusses en route aircraft which are assumed to be linked by real time data bases like ADS-B and can be considered as a constant velocity motion. The proposed approach uses probabilistic trajectory model supposed to have uncertain(More)
Uterine papillary serous carcinoma (UPSC) is an aggressive form of endometrial cancer characterized by a high recurrence rate and poor prognosis. We report a case of a 58-year-old post-menopausal woman with an abdominal wall metastasis in stage IA UPSC. After surgical staging, she did not receive additional adjuvant therapy. An egg sized palpable mass(More)
[Purpose] The purpose of this study was to examine the effects of smoking on teenagers' internal oblique (IO) and transverses abdominis (TrA) expiratory muscles and their pulmonary function. [Subjects] A total of 30 healthy teenagers (15 smokers; 15 nonsmokers) voluntarily participated in the study. [Methods] The subjects were instructed to maintain an(More)
The East/Japan Sea (hereafter, the East Sea) is highly dynamic in its physical phenomena and biological characteristics, but it has changed substantially over the last several decades. In this study, a recent decadal trend of primary productivity in the East Sea was analyzed based on Moderate-Resolution Imaging Spectroradiometer (MODIS)-derived monthly(More)
BACKGROUND The question of whether patients with pure stage I squamous cell carcinoma in a mature cystic teratoma (MCT) should undergo conservative surgery, or postoperative adjuvant treatment remains unresolved. CASE A 33-year-old woman with a left ovarian cyst underwent laparoscopic cystectomy at 16 weeks of gestation. Histological examination confirmed(More)
A Shock position control law of a ramjet engine with variable nozzle throat is proposed. To address the nonlinearity of engine internal nature, an engine model structure which defines sequentially propagated internal flows from inlet to nozzle throat is used such that the effectiveness of nozzle throat variance to intake shock position is mechanized. The(More)
Lipoleiomyoma is an uncommon neoplasm of the uterus, composed of smooth muscles intermixed with mature adipocytes. These tumors are considered a benign variant of uterine leiomyomas. Herein, we report six cases of lipoleiomyoma experienced in our institution from January 2005 to March 2015. The patients ranged in age from 45 to 70 years; the etiology may be(More)
Meigs' syndrome is a benign ovarian tumor associated with ascites and pleural effusion. Elevated cancer antigen 125 (CA-125) in Meigs' syndrome is an unusual clinical condition reported in few cases. We report here on a 61-year-old woman who presented with dyspnea; in imaging assessment, a heterogeneous pelvic mass measuring 12 × 11 cm with ascitic fluid(More)
The dehydroformylation of aldehydes to generate olefins occurs during the biosynthesis of various sterols, including cholesterol in humans. Here, we implement a synthetic version that features the transfer of a formyl group and hydride from an aldehyde substrate to a strained olefin acceptor. A Rhodium (Xantphos)(benzoate) catalyst activates aldehyde(More)
Pure primary ovarian squamous cell carcinoma (SCC) is a rare lesion that usually arises from the malignant transformation of an existing ovarian dermoid cyst. The de novo occurrence of an ovarian SCC in the absence of a prior ovarian dermoid cyst, Brenner tumor or endometriosis is extremely rare. At present, no effective therapy exists for treating pure(More)
