High-Resolution Nanoscale Solid-State Nuclear Magnetic Resonance Spectroscopy

, 2017
We present a new method for high-resolution nanoscale magnetic resonance imaging (nano-MRI) that combines the high spin sensitivity of nanowire-based magnetic resonance detection with high spectral resolution nuclear magnetic resonance (NMR) spectroscopy.

Alternative Route to Strong Interaction: Narrow Feshbach Resonance

, 2012
We show that a narrow resonance produces strong interaction effects far beyond its width on the side of the resonance where the bound state has not been formed.

Resonances and resonance widths [PDF]

, 1986
Two-dimensional betatron resonances are much more important than their simple one-dimensional counterparts and exhibit a strong dependence on the betatron phase advance per cell. A practical definition of ''width'' is expanded upon in order to display these relations in tables.

Stochastic resonance [PDF]

Scholarpedia, 1993
Stochastic resonance (SR) - a counter-intuitive phenomenon in which the signal due to a weak periodic force in a nonlinear system can be {\it enhanced} by the addition of external noise - is reviewed.

Model-Independent Production of a Top-Philic Resonance at the LHC

, 2014
We investigate the collider phenomenology of a color-singlet vector resonance, which couples to the heaviest quarks, the top quarks, but very weakly to the rest of the fermions in the Standard Model.

Reference ranges (“normal values”) for cardiovascular magnetic resonance (CMR) in adults and children: 2020 update

Journal of Cardiovascular Magnetic Resonance, 2020
Cardiovascular magnetic resonance (CMR) enables assessment and quantification of morphological and functional parameters of the heart, including chamber size and function, diameters of the aorta and pulmonary arteries, flow and myocardial relaxation ...

Seventy-Two-Hour Preservation, Resuscitation, and Transplantation of an Isolated Rat Heart with High Partial Pressure Carbon Monoxide Gas (PCO = 400 hPa) and High Partial Pressure Carbon Dioxide (PCO = 100 hPa)

Cell Transplantation, 2010
The cardiac cavity of an isolated rat heart was filled with a Krebs-Henseleit (KH) solution, and the heart was hung in a high-pressure chamber. After the high-pressure chamber had been filled with a mixed gas (PCO = 400 hPa, PCO 2 = 100 hPa, PO 2 = 900 ...

Prognostic value of vasodilator stress perfusion cardiovascular magnetic resonance after inconclusive stress testing

Journal of Cardiovascular Magnetic Resonance, 2021
Background While current guidelines recommend noninvasive testing to detect coronary artery disease, stress tests are deemed inconclusive in a quarter of cases.

Imaging and Hemodynamic Characteristics of Vulnerable Carotid Plaques and Artificial Intelligence Applications in Plaque Classification and Segmentation

Brain Sciences, 2023
Stroke is a massive public health problem. The rupture of vulnerable carotid atherosclerotic plaques is the most common cause of acute ischemic stroke (AIS) across the world. Currently, vessel wall high-resolution magnetic resonance imaging (VW-HRMRI) is

Observation of pinning mode of stripe phases of 2D systems in high Landau levels

, 2008
We study the radio-frequency diagonal conductivities of the anisotropic stripe phases of higher Landau levels near half integer fillings. In the hard direction, in which larger dc resistivity occurs, the spectrum exhibits a striking resonance, while in ...
