The design and application of ultra-broadband excitation pulses have been among the most interesting and timely areas in NMR and EPR methodology in recent years, due especially to advances in hardware design in EPR, the advent and popularity of high- and ultrahigh-field NMR, and the application of numerical methods like optimal control theory to the design and optimization of radiofrequency pulses and pulse sequences. In this communication, we present a short, robust, and flexible version of the CHORUS family of constant-phase, very broadband excitation sequences. We demonstrate that more than 0.5 MHz excitation with uniform amplitudes and phases can be achieved with this excitation sequence.

Compensating attosecond chirp (atto-chirp) of broadband high-order harmonic pulses in the water window region (282 to 533 eV) is a major challenge, due to the lack of natural materials that exhibit ne...
This study aims to find an effective chirp signal that enhances the amplitude of wave-I of auditory brainstem response (ABR) to diagnose "cochlear synaptopathy." Although several chirp signals have be...
We numerically and experimentally investigate a broadband, polarization-independent and wide-incident-angle metamaterial perfect absorber (MPA) based on conductive polymer. By optimizing the electrica...
The self-powered and ultra-broadband photodetectors based on photothermoelectric (PTE) effect are promising for diverse applications such as sensing, environmental monitoring, night vision and astrono...
Comprehensive identification of RNA-binding proteins by mass spectrometry (ChIRP-ms) is a novel technique for studying endogenous ribonucleoprotein complexes. ChIRP-ms is robust across a wide range of...
The purpose of the study is to determine the frequency of UVB radiations necessary to maintain the Vitamin D level during winter time.
In this exploratory study, we hope to learn if treatment of broadband light with infrared light can alter the molecular pathways associated with aging. Secondary exploratory objective is t...
An observational study aiming to study the natural history of a UK-wide patient cohort with ATP1A3-related disease.
The primary objective of this study is to compare visual degradation in a stressed (forced stare) environment in patients before and after acute administration of Systane Ultra.
The objective of this study is to evaluate the efficacy of Rohto Dry-Aid® in comparison to Systane® Ultra on visual function and tear film stability in patients diagnosed with Dry Eye.
A loosely defined group of drugs that tend to increase behavioral alertness, agitation, or excitation. They work by a variety of mechanisms, but usually not by direct excitation of neurons. The many drugs that have such actions as side effects to their main therapeutic use are not included here.
A group of conditions in which HEART VENTRICLE activation by the atrial impulse is faster than the normal impulse conduction from the SINOATRIAL NODE. In these pre-excitation syndromes, atrial impulses often bypass the ATRIOVENTRICULAR NODE delay and travel via accessory pathways connecting the atrium directly to the BUNDLE OF HIS.
A form of ventricular pre-excitation characterized by a normal PR interval and a long QRS interval with an initial slow deflection (delta wave). In this syndrome, the atrial impulse travel to the ventricle via the Mahaim fibers which connect ATRIOVENTRICULAR NODE directly to the right ventricle wall (nodoventricular pathway) or to the RIGHT BUNDLE BRANCH OF HIS (nodofascicular pathway).
Fluorescence microscopy utilizing multiple low-energy photons to produce the excitation event of the fluorophore. Multiphoton microscopes have a simplified optical path in the emission side due to the lack of an emission pinhole, which is necessary with normal confocal microscopes. Ultimately this allows spatial isolation of the excitation event, enabling deeper imaging into optically thick tissue, while restricting photobleaching and phototoxicity to the area being imaged.
