We employ the technique of optical detection magnetic resonance to study dipolar interaction in diamond between nitrogen-vacancy color centers different crystallographic orientations and substitutional nitrogen defects. demonstrate measurements resonant spin flips-flips (second Larmor line), flip-flops ensembles diamond. In addition, strain coupling bulk acoustic modes is studied using detectio...

vestibular schwannoma is the most common tumor of the posterior fossa of the skull. patients referred with the primary otologic symptoms such as hearing loss, tinnitus, vertigo, imbalance, and the cranial nerve palsy. thirty-three patients were operated and treated by a team of otolaryngologist and neurosurgeon, anudiometrist, and internist. patients'chiefcomplaint was due to 94% hearing l...

theoretical investigations on the characteristics of the nuclear quadrupole resonance and the influence of the magnetic effect on it have been carried out. the magnetic dipole effect on the quadrupole resonance for the two spins i and i with different values oft) and e has been studied. the energy levels and their transition probabilities are presented with their corresponding spectra. the firs...

colloid carcinoma, also called mucinous carcinoma, is classified as a histologic variant of adenocarcinoma. because the colloid carcinoma of the biliary tree is exceedingly rare, the imaging characteristics and the clinical features of colloid carcinoma remain relatively unknown. we report a case of colloid carcinoma of the common bile duct and its accompanied metastatic lymphadenopathies with ...

Introduction: Photothermal therapy (PTT) is a nanotechnology-assisted cancer hyperthermia approach in which the interaction between laser light and plasmonic nanoparticles generates a localized heating for thermoablation of the tumor. Recent efforts in the area of PTT follow two important aims: (i) exploitation of targeting strategies for preferential accumulation of plasmonic ...

Background and Aim: Topography of the human insula has occasionally been studied in different populations. The purpose of this study was to evaluate the morphology of human insula in Iranian population and its relationship with sex, age, and handedness via magnetic resonance imaging. Methods and Materials/Patients: In our study, 380 normal magnetic resonance imaging were enrolled. The number...

Surface acoustic waves (SAWs) in the GHz frequency range are exploited for the all-elastic excitation and detection of ferromagnetic resonance (FMR) in a ferromagnetic-ferroelectric (Ni/LiNbO(3)) hybrid device. We measure the SAW magnetotransmission at room temperature as a function of frequency, external magnetic field magnitude, and orientation. Our data are well described by a modified Landa...

Introduction Assessment of aortic valve area (AVA) is primarily carried out by echocardiography in clinical routine. In cases of insufficient acoustic window, discrepant medical findings or suboprimal Doppler conditions, 1.5 T magnetic resonance imaging (MRI) is discussed as an noninvasive alternative imaging method for planimetry of AVA. If quantification of AVA is also possible at higher magn...
