A decreased inspiratory capacity (IC)/total lung capacity (TLC) ratio is associated with dynamic hyperinflation and decreased exercise capacity. The present authors hypothesised that static (low IC/TLC) and dynamic hyperinflation impair cardiac function as assessed by oxygen pulse at rest and during cardiopulmonary exercise testing (CPET). Lung function, body mass index, hand grip strength and ...

The aim of our study was to optimise electric pulse parameters for electrochemotherapy by sampling the space of pulse parameter variables using systematic in vitro experiments. For this purpose we defined parameters that describe the effectiveness of different sets of electric pulse parameters in vitro and combined them into an objective function that characterises requirements for successful e...

Pulse compression technique is used to enhance radar performance in terms of more efficient use of high power transmitters and increasing the system resolving capability. The polyphase pulse compression codes (P3 and P4) which are derived from linear frequency modulated waveforms have low sidelobes and are Doppler tolerant. To reduce the sidelobes further different types of windows have been us...

background thrombolytic therapy in patients with sub-massive pulmonary embolism (smpte) needs further assessment. objectives the current study aimed to assess a potential benefit of thrombolytic and non-thrombolytic therapy in patients with smpte. patients and methods one hundred-nineteen patients were enrolled with smpte from 2006 to 2010 in the tertiary care center of rajaie medical and resea...

introduction: a modern technique for elemental analysis of biological samples is laser induced breakdown spectroscopy (libs). this technique is based on emission of excited atoms, ions, and molecules in plasma produced by focusing a high power laser pulses on sample surface. because of several advantages of libs including little or no sample preparation; minimally invasive; fast analysis time a...

In this work, various dispersion compensation methods are designed and evaluated to search for a cost-effective technique with remarkable dispersion compensation and a good pulse shape. The techniques consist of different chirp functions applied to a tanh fiber Bragg grating (FBG), a dispersion compensation fiber (DCF), and a DCF merged with an optimized linearly chirped tanh FBG (joint techniq...

Arterial pulse wave analysis in time and frequency domain was carried out to find out biophysical and functional properties of artery walls measured with a photoplethysmographic (PPG) device. Because peripheral arterial disease (PAD) is a fatal problem all over the world, an easy diagnosis method would be needed. It could probably be diagnosed by PPG which is a non-invasive optical technique fo...
