Herein, a new methodology using a 3D Electromagnetic (EM) simulator-based Support Vector Regression Machine (SVRM) models of base elements is presented for band-pass filter (BPF) design. SVRM models of elements, which are as fast as analytical equations and as accurate as a 3D EM simulator, are employed in a simple and efficient Cuckoo Search Algorithm (CSA) to optimize an ultrawideband (UWB) m...

An emergent clone of Haemophilus influenzae biogroup aegyptius (Hae) is responsible for outbreaks of Brazilian purpuric fever (BPF). First recorded in Brazil in 1984, the so-called BPF clone of Hae caused a fulminant disease that started with conjunctivitis but developed into septicemic shock; mortality rates were as high as 70%. To identify virulence determinants, we conducted a pan-genomic an...

A group of compounds structurally similar to bis(4-hydroxyphenyl)propane (bisphenol A, BPA) are called bisphenols (BPs), and some of them can partially replace BPA in industrial applications. The production and consumption of BPs other than BPA, especially those of bis(4-hydroxyphenyl)methane (bisphenol F, BPF) and bis(4-hydroxyphenyl)sulfone (bisphenol S, BPS), have increased recently, leading...

In this paper, modification in the computational methods, for solving Non-linear Volterra integral equations, is presented. Here, two piecewise constant methods are considered for obtaining the solutions. The first method is based on Walsh Functions (WF) and the second method is via Block Pulse Functions (BPF). Comparison between the two methods is presented by calculating the errors vis-à-vis ...

---------------------------------------------------------------------------------------------------------------------------------------------Abstract: -In this paper, a compact ultra wideband (UWB) bandpass filter (BPF) with a passband covering 4.73 GHz to 10.43GHz with a bandwidth of 5.7 GHz and a fractional bandwidth of 75.2% is proposed. The filter has three transmission poles in the passban...

BACKGROUND The incidence of a bronchopleural fistula (BPF) as a major complication after non-small cell lung carcinoma (NSCLC) surgery has decreased in recent years, due to new surgical refinements and a better understanding of the bronchial healing process. We reviewed our most recent experience with BPFs and tried to determine methods which may effectively reduce its occurrence. METHODS Dat...

Abstract—This paper presents a novel compact microstrip hybrid four-mode bandpass filter (BPF) with good selectivity and multitransmission zeros. By adding an external resonator to a triplemode stub-loaded resonator, four modes are generated in the desired passband and a hybrid four-mode BPF is implemented. Oddand even-mode theory is introduced to investigate the mode characteristics of triple-...

The aim of this study was to evaluate possible interactions between severity of borderline personality features (BPFs), dissociative experiences, and alexithymia among substance-dependent men while controlling for their current age, depression, and anxiety. Participants were 200 substance-dependent men consecutively admitted to a dependency treatment unit. The Borderline Personality Inventory, ...
