—This paper develops a practical design method for implementing Tomlinson–Harashima precoding (THP) in a downlink channel with multiple antennas at the transmitter and a single antenna at each receiver. A two-step design process is proposed for minimizing the total transmit power while satisfying every user's minimum data rate and maximum bit-error rate(More)
A 25-year-old Uzbek male presented with right upper abdominal pain for 20 days. On radiologic studies, a huge cystic mass was noticed in the right liver which was suspected as parasitic. The patient received right hepatic segmentectomy (segment 7), and the surgically resected mass was confirmed as cystic echinococcosis (CE), measuring 10.5 cm in its(More)
Prediction of malignancy or invasiveness of branch duct type intraductal papillary mucinous neoplasm (Br-IPMN) is difficult, and proper treatment strategy has not been well established. The authors investigated the characteristics of Br-IPMN and explored its malignancy or invasiveness predicting factors to suggest a scoring formula for predicting pathologic(More)
BACKGROUNDS/AIMS To compare surgical results and survival of two groups of patients, age ≥70 vs. age <70, who underwent pancreaticoduodenectomy and to identify the safety of this procedure for elderly patients for the treatment of distal common bile duct (CBD) cancer. METHODS Between January 2003 and December 2009, 55 patients who underwent(More)
