Today the industry depends on various types of three-phase induction machines, requiring operating at variable speeds to perform more complex processes. Therefore, it is vital to monitor their operati…
The sustained increase in new cases of COVID-19 across the world and potential for subsequent outbreaks call for new tools to assist health professionals with early diagnosis and patient monitoring. G…
Over the past few years, automatic recognition of human interactions has drawn significant attention from researchers working in the field of Artificial Intelligence (AI). And feature extraction is on…
This study utilized a comprehensive nomogram to evaluate the prognosis of patients with COVID-19 pneumonia. COVID-19 pneumonia data was divided into training set (256 of 321, 80%), internal validation…
Thresholds for the detection of motion in depth in the median plane of the head are substantially poorer than those for motion in the frontoparallel plane. This suggests the existence of two independe…
Heart rate (HR) power spectral indexes are limited as measures of the cardiac autonomic nervous systems (CANS) in that they neither offer an effective marker of the beta-sympathetic nervous system (SN…
We describe a variety of new ultrasound techniques by their physical background, potentials and applications regarding usefulness during intra-operative neurosurgical procedures. Transducers like high…
Although many blood flow models have been constructed for cerebral arterial trees, few models have been reported for their venous counterparts. In this paper, we present a computational model for an a…
The structure and hydrogen bonding of water in an aqueous solution of amphoteric copolymers (poly(MA-r-DMAPMA), 3x10(3)<M(w)<10(4)) composed of various ratios of methacrylic acid (MA) and N-[3-(dimeth…
Part of the energy produced by the heartbeat is transferred to the lung and promotes intrapulmonary gas mixing. It is likely that this transmission in the form of local mechanical disturbances affects…
Additional information on an x-ray picture of peribronchial changes in tumorous and non-tumorous lesions of the lungs were obtained in 54 patients (40 with bronchogenic, mostly central cancer and 14 w…
1. The effects of muscarinic receptor antagonists considered to be selective for M1 receptors (pirenzepine; PZ), M2 receptors (AFDX-116), and for M3 receptors (4-diphenyl acetoxy N-methyl-piperidine (…
A new, integrated digital signal processing (DSP) system, the Personal Acoustics Lab (PAL), is described. This microcomputer-based system is suitable for analogue signal digitization at rates from sev…
The field of robotic thoracic surgery has exploded in the last five years. Robotic technology allows the surgeon to perform complex operations with smaller incisions. As robotic systems become smaller…
PURPOSE: A system for digital integration of an open MR scanner (0.23 T, Figure 1) in therapy simulation and 3D radiation treatment planning is described.METHOD: MR images were acquired using the body…
Robot-assisted lobectomy has been reported elsewhere as a feasible technique for lobectomy. We report a modification of the previously reported technique using a complete port-access approach without …
Anthropomorphic models used in computational dosimetry, also denominated phantoms, are based on digital images recorded from scanning of real people by Computed Tomography (CT) or Magnetic Resonance I…
The contourlet transform was proposed to address the limited directional resolution of the separable wavelet transform. One way to guarantee good approximation behavior is to let the directional filte…
The combination of medical imaging with computational fluid dynamics (CFD) has enabled the study of 3-D blood flow on a patient-specific level. However, with models based on gated high-resolution data…
Little is known about the factors influencing individual selection and consumption of fats or the role of sensory preferences in this process. Thirty human subjects kept diet records for 10 d and then…
