The receiver function (RF) technique is a well-established method to investigate the crustal and upper mantle structures based on three-component seismograms of teleseismic events. In the present study, we propose a modified automatic procedure to determine the back azimuth and polarization angles of a teleseismic event based on the RF technique. The method is tested for the recording of 3 perm...

root-knot nematodes, meloidogyne spp., are one of the important plant parasitic nematodes of tomato in the world. the most suitable control method of plant parasitic nematodes is the use of resistance sources and tolerant cultivars. in the earlier studies, the results showed thatonly 2% (19 out of 537 varieties) were resistant and tolerant to the root knot nematodes. in the supplementary studie...

Introduction: RF field non-uniformities caused by shortened RF wavelengths in human tissue significantly affect the image quality, especially for high-field MRI [1]. Spiral coils [2, 3] have been put forth to improve field homogeneity. In addition, RF shimming based on a TEM coil [4] or an RF transmit array [5] is an efficient method to address such non-uniformities. In this work, we combine th...

PURPOSE This study shows the potential of magnetic resonance electrical impedance tomography (MREIT) as a non-invasive RF ablation monitoring technique. MATERIALS AND METHODS We prepared bovine muscle tissue with a pair of needle electrodes for RF ablation, a temperature sensor, and two pairs of surface electrodes for conductivity image reconstructions. We used the injected current non-linear...

With the globalization of integrated circuit (IC) design flow and the outsourcing of chip fabrication service, intellectual property (IP) piracy and malicious logic insertion become main security threats to tamper hardware infrastructures. While most of the protection methods are dedicated for digital circuits, we try to protect radio-frequency (RF) designs which are more likely to be IP piracy...

Cohort identification is an important step in conducting clinical research studies. Use of ICD-9 codes to identify disease cohorts is a common approach that can yield satisfactory results in certain conditions; however, for many use-cases more accurate methods are required. In this study, we propose a bootstrapping method that supplements ICD-9 codes with lab results, medications, etc. to build...

prevalence of thyroid nodules diagnosed by ultrasonography has been reported to be high (about 50%) probably due to iodine deficiency in our region. most thyroid nodules benign but some require treatment for cosmetic reasons or subjective symptoms. the conventional method of treatment in iran is surgery. for the first time in iran, from february 2016, 50 patients with 63 nodules (solid or cysti...
