In this paper, a novel design method for a dual-band bandpass filter (BPF) with arbitrary controllable bandwidths based on a simple frequency mapping function is proposed and its analytical design equations are also derived. The circuit conversion techniques are employed for implementation with distributed transmission line. To validate the proposed dual-band BPF with controllable bandwidths, a...

In this paper, a novel structure of One-Third-Mode Substrate Integrated Waveguide Resonator (OTMSIWR) is first proposed, which reduces about 65% size. Based on the OTMSIWR, a single-band bandpass filter (BPF) operats at 4.55GHz is designed. The single-band BPF has a wide and deep upper stopband. Further, a dual-band BPF using high mode technology based on the single-band filter is designed. The...

BACKGROUND Although bipolar disorder (BD) and borderline personality disorder (BPD) share clinical characteristics and frequently co-occur, their interrelationship is controversial. Especially, the differentiation of rapid cycling BD and BPD can be troublesome. This study investigates the relationship between borderline personality features (BPF) and prospective illness course in patients with ...

The possible linear short-term coordination between respiratory movements (RESP), heart rate fluctuations (HRF), and arterial blood pressure fluctuations (BPF) in conscious human beings has not yet been investigated because of the restricted time resolution of conventional time series analysis. At present, this short-term dynamics as an expression of relative coordination can be quantified by n...

Terzi et al. [1] for their comments on our article [2] and also thank EJCTS for giving me this opportunity to answer this question. Bronchopleural fistula (BPF) is a most serious complication in patients with tuberculosis-destroyed lungs who have undergone pneumonectomy. Halezeroglu et al. [3] consider that tuberculosis and preoperative empyema lead to BPF. We believe that the risk factors for ...

Recently, graph matching algorithms utilizing the path following strategy have exhibited state-of-the-art performances. However, the paths computed in these algorithms often contain singular points, which usually hurt the matching performance. To deal with this issue, in this paper we propose a novel path following strategy, named branching path following (BPF), which consequently improves grap...

RATIONALE The development of postoperative bronchopleural fistula (BPF) remains a challenge in thoracic surgery. We herein report a case of BPF successfully treated with endoscopic bronchial occlusion under computed tomography (CT) fluoroscopy and virtual bronchoscopic navigation (VBN). PATIENT CONCERNS A 63-year-old man underwent right upper lobectomy with concomitant S6a subsegmentectomy fo...

Myotonic dystrophy (DM1) and proximal myotonic myopathy (PROMM or DM2) are two distinct muscular disorders with multisystemic involvement. Both have previously been reported to be associated with cognitive impairment and white matter lesions detected by cerebral magnetic resonance imaging (MRI). In this study, the extent of brain atrophy was investigated in vivo in ten DM1 and nine PROMM patien...

The explosive advancement of wireless communication devices for multiband and multi-standard applications such as Wi-Fi, WiMAX, Bluetooth, and cellular networks demands low-cost, lightweight, small form factor, and high performance radio frequency (RF) front-end modules. In the multiband or multi-standard devices, the bandpass filter (BPF) is an essential functional block to avoid signal interf...

This paper introduces a theoretical analysis as well as a design example for bandpass filters (BPF) with a distinctive topology. Based on the analysis of simple two-port symmetrical lossless networks with a parallel structure, a method for obtaining normalized BPF prototypes with desired bandwidths was developed. These prototypes can be scaled to any central frequency and symmetrical real termi...
