Abstract—This paper proposes a complementary combination scheme of affine projection algorithm (APA) filters with different order of input regressors. A convex combination provides an interesting way to keep the advantage of APA having different order of input regressors. Consequently, a novel APA which has the rapid convergence and the reduced steady-state error is derived. Experimental result...

Doğal afetler arasında, kuraklık hem doğal de insan yapımı sistemler üzerinde uzun süreli etkiye sahip olmasından dolayı en zararlı olan afet olarak sınıflandırılmaktadır. Kuraklığın sebep olduğu sonuçlar arasında su kıtlığı, tarımsal kayıplar, hidroelektrik arzın azalması, depolanan kaynakların kaybı, yangınlar, kıtlık, işgücünde veya üretkenlikte azalma kitlesel göçler sayılabilir. Dünyada me...

The importance of bacterial, phytoplankton and dissolved alkaline phosphatase activity (APA) in the northern Adriatic was investigated during 2006. In surface waters total APA increased from early spring (0.07-0.08 micromol l(-1) h(-1)) to late spring (up to 4.64 micromol l(-1) h(-1)) and remained relatively high during the summer (0.46-0.71 micromol l(-1) h(-1)), due to an increase in specific...

OBJECTIVES Recently, somatic mutations in KCNJ5, ATP1A1, ATP2B3, and CACNA1D genes were found to be associated with the pathogenesis of aldosterone-producing adenoma (APA). This study aimed to investigate the prevalence of somatic mutations in KCNJ5, ATP1A1, ATP2B3, and CACNA1D and examine the correlations between these mutations and the clinical and biochemical characteristics in Korean patien...

PROBLEMS 1) Does the administration of heparin and aspirin (H/A) in combination with intravenous immunoglobulin G (IVIG) improve in vitro fertilization (IVF) implantation and birth rates in patients with recurrent IVF failure? 2) Is the effect of such treatment related to the antiphospholipid antibody (APA) status of the patients concerned? METHOD OF STUDY Subjects consisted of 89 women young...

The mechanisms of excess aldosterone secretion in primary aldosteronism (PA) remain poorly understood, although a role for circulating factors has been hypothesized for decades. Agonistic autoantibodies against type-1 angiotensin-II receptor (AT1AA) are detectable in malignant hypertension and preeclampsia and might play a role in PA. Moreover, if they were elevated in aldosterone-producing ade...

Background. The persistent presence of antiphospholipid antibodies (APA) may lead to the development of primary or secondary antiphospholipid syndrome. Although the genetic basis of APA has been suggested, the identity of the underlying genes is largely unknown. In this study, we have performed a genome-wide association study (GWAS) in an effort to identify susceptibility loci/genes for three m...

BACKGROUND Recurrent pregnancy loss (RPL) has been associated with antiphospholipid antibodies (APA) including anticardiolipin and lupus anticoagulant. Therapy using heparin and aspirin has been shown to significantly improve the live birth rate. We evaluated whether other APA should be considered as a basis for treatment in women with RPL. We also assessed the efficacy of heparin and aspirin t...

Breast cancer (BC) is a leading cause of cancer-related mortality in females and is recognized as a molecularly heterogeneous disease. Previous studies have suggested that alternative messenger RNA (mRNA) processing, particularly alternative polyadenylation [poly(A)] (APA), can be a powerful molecular biomarker with prognostic potential. Therefore, in the present study, we profiled APA sites in...
