OBJECTIVE To analyze patterns of abdominopelvic failures and to define subgroups for the use of adjuvant radiotherapy in the International Federation of Gynecology and Obstetrics (FIGO) stage III epithelial ovarian cancer (EOC). METHODS We reviewed 149 patients treated with debulking surgery followed by intravenous taxane and platinum chemotherapy between 1999 and 2008. Patient characteristic...

OBJECTIVES Antikeratin antibodies (AKA) and antiperinuclear factor (APF) are specific antibodies found very early in rheumatoid arthritis (RA). The objective of this eight year follow up study was to assess the value of early AKA and APF assays in predicting functional disability and cartilage damage. METHOD In 2000, 64 patients tested for AKA and APF (antifilaggrin antibodies) between 1990 a...

Opisthorchis viverrini is distinct among helminth infections as it drives a chronic inflammatory response in the intrahepatic bile duct that progresses from advanced periductal fibrosis (APF) to cholangiocarcinoma (CCA). Extensive research shows that oxidative stress (OS) plays a critical role in the transition from chronic O. viverrini infection to CCA. OS also results in the excision of a mod...

Intrahepatic arterioportal fistulas (APF) are uncommon complications following hepatic trauma. Large fistulas can result in portal hypertension and cardiovascular compromise. A 46-year-old patient is described who presented with portal hypertension, variceal bleeding, and high output cardiac failure due to a large intrahepatic APF. Surgical closure of the APF by hepatic resection successfully r...

This paper presents an effective improved artificial potential field-based regression search (improved APF-based RS) method that can obtain a better and shorter path efficiently without local minima and oscillations in an environment including known, partially known or unknown, static, and dynamic environments. We redefine potential functions to eliminate oscillations and local minima problems,...

In this paper, a model reference adaptive sliding mode (MRASMC) using a radical basis function (RBF) neural network (NN) is proposed to control the single-phase active power filter (APF). The RBF NN is utilized to approximate the nonlinear function and eliminate the modeling error in the APF system. The model reference adaptive current controller in AC side not only guarantees the globally stab...

A current source converter (CSC) based shunt active power filter (APF) system is designed and implemented to suppress the amplification of low order harmonics at the medium voltage (MV) interface bus between the distribution and transmission systems. Four CSC based APF modules designed at 1.0 Kv are operated in parallel, and connected to the 31.5 kV MV bus via a specially designed coupling tran...

In this paper presents control method for hybrid active filter using space vector pulse width modulation (SVPWM). In the proposed control method, the Active Power Filter (APF) reference voltage vector is generated instead of the reference current, and the desired APF output voltage is generated by SVPWM. A MATLAB code is developed to generate the SVPWM switching pulses fed to the two-level inve...

This paper main intents to present a flying capacitor multilevel inverter based shunt active power filter(APF) with Sigma-Delta modulation. A multilevel Sigma-Delta modulation(SDM) control can be applied to control power section of APF intention to reducing sensitivity to flying capacitor voltage deregulation and mending modulator performance. In these control section of APF perfect harmonic ca...

A major challenge in shared path protection is to select a jointly optimized pair of active and backup paths. While Integer Linear Programming (ILP) based approaches are notoriously time consuming, existing heuristics such as active path first (APF) can only achieve sub-optimal results. In this paper, we propose a novel heuristic called APF with potential backup cost or APF-PBC under the distri...
