An autonomous distributed LQR/APF control algorithm for multiple small spacecraft during simultaneous close proximity operations has been developed. This research contributes to the control of multiple small spacecraft for emerging operation, which may include inspection, assembly, or servicing. A control algorithm is proposed which combines the control effort efficiency of the Linear Quadratic...

Xiexin decoction, a herbal therapeutic agent commonly used in traditional Chinese medicine, is recognized for its beneficial effects on diabetic nephropathy exerted through the combined action of multiple components, including Rhizoma Coptidis alkaloids (A), Radix et Rhizoma Rhei polysaccharides (P), and Radix Scutellaria flavones (F). Our previous studies have shown that a combination of A, P,...

BACKGROUND Urinary bladder cancer is a common malignancy worldwide, and outcomes for patients with advanced bladder cancer remain poor. Antiproliferative factor (APF) is a potent glycopeptide inhibitor of epithelial cell proliferation that was discovered in the urine of patients with interstitial cystitis, a disorder with bladder epithelial thinning and ulceration. APF mediates its antiprolifer...

Current information extraction systems can do a good job of discovering entities, relations and events in natural language text. The traditional output of such systems is XML, with the ACE Pilot Format (APF) schema as a common target. We are developing a system that will take the output of an information extraction system as APF documents and directly populate a knowledge base with the informat...

OBJECTIVE In this paper we evaluated the effect of two fluoridated agents and Nd:YAG irradiation separately and in combination on dentine resistance to erosion. BACKGROUND DATA The morphological changes in dentin induced by laser treatment may reduce the progression of erosive lesions. Due to the possibility of a synergistic effect of laser with fluoride, this study was conducted. MATERIALS...

OBJECTIVES The purpose of this study was to compare the success rate of successful arterial peak flow (APF) and ankle-brachial index (ABI) measurements in patients with suspected or known peripheral arterial disease (PAD). MATERIALS AND METHODS 183 patients with varying degrees of PAD were included. All subjects underwent ABI measurements and MR imaging of the popliteal artery to determine AP...

The color of dental restorative material should be maintained throughout its functional lifetime in an oral environment. However, the frequent use of mouthwash may affect the color stability of these composite restorations. The aim of this study is to assess the effects of using various mouthwashes on the color stability of various dental restorative composite materials. For this purpose, four ...

The objectives of this study were to investigate the effect of application times on fluoride (F) uptake by sound enamel exposed in vitro to APF gels. Two groups of 12 teeth each were treated with one of the following 1.23% APF gels: MinuteGelTM (gel A) and Nupro® (gel B). The F treatment times were 1, 2, and 4 min and the F concentrations and enamel biopsy depths were determined using an acid-e...
