In the framework of metric spaces, we introduce concept Geraghty-Ciric type contractions and show existence uniqueness fixed point such mappings. This result improves unifies those obtained by Geraghty (Proc. Amer. Math. Soc. 40, 604-608 (1973)) Ciric 45, 267-273, (1974)). Several technical lemmas are employed to ensure that a Picard sequence is Cauchy sequence. addition, two illustrative examp...

We propose an alternating optimization framework for the joint design of excitation k-space trajectory and RF pulses for smalltip-angle parallel excitation. Using Bloch simulations, we show that compared with conventional designs with predetermined trajectories, joint designs can often excite target patterns with improved accuracy and reduced total integrated pulse power, particularly at high r...

OBJECTIVE The purpose of this study was to evaluate risk factors of vaginal cuff dehiscence or evisceration according to the type of operation. METHODS Medical records of 604 women who underwent hysterectomies at Korea University Anam Hospital between June 2007 and June 2011 were reviewed. They were allocated to six groups. The six types of hysterectomies included robotic hysterectomy (n = 7)...

BACKGROUND Studies of severely injured patients suggest that advanced pre-hospital care and/or rapid transportation provides a survival benefit. This benefit depends on the disposition of resources to patients with the greatest need. Norway has 19 Emergency Helicopters (HEMS) staffed by anaesthesiologists on duty 24/7/365. National regulations describe indications for their use, and the use of ...

OBJECTIVE We aimed to investigate the prevalence and etiology of potassium abnormalities (hypokalemia and hyperkalemia) and management approaches for hospitalized patients. SUBJECTS AND METHODS Over a 4-month period, all hospitalized patients at Hacettepe University Medical Faculty Hospitals who underwent at least one measurement of serum potassium during hospitalization were included. Data o...

Successful control of blood pressure relies on identification of secondary causes and contributing factors of hypertension. As antihypertensive medication can interfere with diagnostic investigations, temporary discontinuation of medication is advised. However, there are concerns about the safety of temporary discontinuation of antihypertensive medication in patients with difficult-to-control h...
