Resting state fMRI (rs-fMRI or R-fMRI), also referred to as task-independent fMRI or task-free fMRI, is a method of functional magnetic resonance imaging (fMRI) that is used in brain mapping to evaluate regional interactions that occur in a resting or task-negative state, when an explicit task is not being performed.
In physics, optically detected magnetic resonance (ODMR) is a technique for detecting quantum objects that are both paramagnetic and optically active.In the case of photoluminescent point defects (color centers) in crystals, the “ODMR signal” usually means a decrease in the defect’s fluorescence intensity under continuous illumination due to a simultaneously applied AC magnetic field.
Increase of amplitude as damping decreases and frequency approaches resonant frequency of a driven damped simple harmonic oscillator. [1] [2]Resonance is a phenomenon that occurs when an object or system is subjected to an external force or vibration that matches its resonant frequency, defined as the frequency that generates the maximum amplitude response in the system.
The Joint Entrance Examination – Advanced (JEE-Advanced) (formerly the Indian Institute of Technology – Joint Entrance Examination (IIT-JEE)) is an academic examination held annually in India that tests the skills and knowledge of the applicants in physics, chemistry and mathematics.
Electrical resonance occurs in an electric circuit at a particular resonant frequency when the impedances or admittances of circuit elements cancel each other. In some circuits, this happens when the impedance between the input and output of the circuit is almost zero and the transfer function is close to one.
Helmholtz resonance, also known as wind throb, refers to the phenomenon of air resonance in a cavity, an effect named after the German physicist Hermann von Helmholtz. [1] This type of resonance occurs when air is forced in and out of a cavity (the resonance chamber ), causing the air inside to vibrate at a specific natural frequency .
Hòa Hảo is a new religious movement [1] and it was named after the founder Huỳnh Phú Sổ's native village of Hoa Hao [1] (Hòa Hảo; [2] Vietnamese: [hwaː˨˩ haːw˧˩] ⓘ; chữ Hán: 和好; literally "peace and amicability"), [15] in what is now Thốt Nốt District of An Giang Province, Vietnam. [16] The name is also spelled as ...
The spectra are read with the pre-selected nuclei giving a large, negative signal while neighboring nuclei are identified by weaker, positive signals. This only reveals which peaks have measurable NOEs to the resonance of interest but takes much less time than the full 2D experiment.
