Nonlinear Dynamics, 2014
An approach is presented to investigate the nonlinear vibration of stiffened plates. A stiffened plate is divided into one plate and some stiffeners, with the plate considered to be geometrically nonlinear, and the stiffeners taken as geometrically nonlinear Euler beams.

Spatiotemporal resonance in mouse primary visual cortex
Current Biology, 2023SUMMARY Human primary visual cortex (V1) responds more strongly, or resonates, when exposed to ∼10, ∼15-20, ∼40-50 Hz rhythmic flickering light. Full-field flicker also evokes perception of hallucinatory geometric patterns, which mathematical models explain as standing-wave formations emerging from periodic forcing at resonant ...

Magnetic resonance characterisation of primary Raynaud’s phenomenon
Journal of Medical Imaging and Radiation Oncology, 2021SummaryThe objective findings of phalangeal T2‐weighted hyperintense and T1‐weighted hypointense bone marrow signal on MRI without features of seronegative arthropathy or osteomyelitis may assist clinicians in making a diagnosis in the appropriate clinical context.

Primary resonance of piezoelectric resonators
1996 IEEE Ultrasonics Symposium. Proceedings, 2002It is found that the nonlinear behavior of piezoelectric resonators is more complicated than that predicted by previous theories. Actually the resonators work as parametrically excited vibration systems. Mode-coupled equations are obtained by means of the boundary integration. The method of multiple scales is used to solve the equations.

Magnetic Resonance Imaging of Primary Cardiomyopathies
Journal of Computer Assisted Tomography, 2003Cardiomyopathies are diseases of the myocardium of unknown etiology associated with cardiac dysfunction. On the grounds of their morphology and pathophysiology, primary or idiopathic cardiomyopathies may be classified into a number of disorders; namely, hypertrophic cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy, dilated cardiomyopathy,

Magnetic Resonance Imaging in Primary Amyloidosis
Acta Radiologica, 1987Twelve patients with primary amyloidosis (AL) were investigated with magnetic resonance imaging (MRI). In 9 patients an abnormal thickening of the heart walls was present and in 2 macroglossia was found at MRI. T1 was significantly increased in liver (p<0.05) and subcutaneous fat (p<0.01) while it was decreased in the spleen (p<0.05).

Magnetic Resonance Imaging in Primary and Secondary Septorhinoplasty
Facial Plastic Surgery, 1996The authors emphasize the importance of MRI as a means to functionally evaluate patients in primary (PR) and secondary (SR) rhinoseptoplasty. Forty-eight subjects were appraised who underwent various types of corrective nose surgery: 31 PR, 12 SR, 4 introgenic perforations, and 1 dermoid cyst of the nasal dorsum.
