Matrix converter is a single-stage converter which directly connects a three-phase voltage source to a three-phase load without dc-link components. Therefore, any harmonic distortion and imbalance in input voltage directly reflect to the output of the converter. Recently, many researchers have made an effort to cope with this problem. In this paper, under distorted input voltage conditions, beh...

Pulse width modulation strategies have been developed for indirect matrix converters (IMCs) in order to improve their performance. In indirect matrix converters, the LC input filter is used to remove input current harmonics and electromagnetic interference problems. Unfortunately, due to the existence of the input filter, the input power factor is diminished, especially during operation at low ...

47 For more than 2 decades, anterior chamber IOLs (AC IOLs) and for more than a decade scleral-fixated posterior chamber (PC) IOLs has been predominant type of lens used in secondary IOL implantation in the absence of capsule support. For the past decade surgeons around the globe have also tried sulcus fixation of a standard PC IOL as a treatment modality in cases with nucleus or IOL drop with ...

cognitive models of obsessive-compulsive disorder (ocd) posit that specific kinds of dysfunctional beliefs underlie the development of this disorder. the aim of present study was to determine whether these beliefs are endorsed more strongly by ocd patients than by those with other anxiety disorders and by community samples. a battery of questionnaires, including the obq-44, moci, bdi-ii, bai, s...

OBJECTIVE To assess the satisfaction of patients with refractory idiopathic overactive bladder (OAB) with two treatment methods, onabotulinumtoxinA (oBTX) and augmentation ileocystoplasty (AC). PATIENTS AND METHODS This prospective study included patients with refractory idiopathic OAB for >6 months and a urodynamic diagnosis of OAB. Oral pharmacotherapy had failed in all patients. Patients w...

BACKGROUND Acupuncture stimulates points on the body, influencing the perception of myofascial pain or altering physiologic functions. OBJECTIVE The aim was to evaluate the effect of electroacupuncture (EAC) and acupuncture (AC) for myofascial pain of the upper trapezius and cervical range of motion, using SHAM acupuncture as control. METHOD Sixty women presenting at least one trigger point...

objective(s):n-myc downstream regulated gene 2 (ndrg2) is a candidate gene for tumor suppression. the expression of ndrg2 is down-regulated in several tumors including lung cancer. the aim of this study was to explore the effect of ndrg2 overexpression on invasion, migration, and enzymatic activity of matrix metalloproteinase-2 (mmp-2) and -9 (mmp-9) in human lung adenocarcinoma a549 cells.  ma...

BACKGROUND AND PURPOSE Patients treated with oral anticoagulants (ACs) have an increased risk of intracerebral hemorrhage (ICH), which is more often fatal than spontaneous ICH. Options to reverse the AC effect include intravenous administration of vitamin K, plasma, and coagulation factor concentrate. However, the optimal management of AC-related ICH has not been determined in any randomized tr...
