First In Vivo ²³Na Human Imaging at 10.5 T Using a Combined Sodium-Proton Transceiver Body Array. [PDF]

Magn Reson Med
ABSTRACT Purpose To demonstrate the first in vivo human 23Na MRI at 10.5 T using a novel dual‐tuned transceiver body array and to evaluate a self‐gating approach for respiratory motion compensation, focusing on renal imaging. Methods A custom‐built eight‐channel 23Na‐loop 1H‐dipole transceiver array was designed, constructed, and characterized.

Projected Density Matrix Embedding Theory with Applications to the Two-Dimensional Hubbard Model [PDF]

, 2019
Density matrix embedding theory (DMET) is a quantum embedding theory for strongly correlated systems. From a computational perspective, one bottleneck in DMET is the optimization of the correlation potential to achieve self-consistency, especially for ...

Conditioning Electrical Stimulation for Patients with Moderate or Severe Carpal Tunnel Syndrome: Double Blinded Randomized Controlled Trial

Annals of Neurology, EarlyView.
Objective Carpal tunnel syndrome (CTS) can drastically impair one's ability to work and interferes with activities of daily living. We recently demonstrated that, in rodents, conditioning electrical stimulation (CES) delivered to the nerve 7 days prior to surgery imparts a conditioning lesion‐like effect by accelerating the rate of regeneration along ...

Broadband Conductance Matching Effect in Conductive Metamirrors

Advanced Physics Research, EarlyView.
A conductance matching effect is revealed in conductive metamirrors whose input conductance can be broadband self‐matched to the free space when the conductivity‐thickness product equals 8 mS. This effect enables thickness‐invariant perfect absorption at low frequencies, and tunable resonances at higher‐order modes, providing new opportunities for ...

Ultra-High-Field Magnetic Resonance Spectroscopy in Psychiatry

Frontiers in Psychiatry, 2017
The advantages of ultra-high-field (UHF ≥ 7T) MR have been demonstrated in a variety of MR acquisition modalities. Magnetic resonance spectroscopy (MRS) can particularly benefit from substantial gains in signal-to-noise ratio (SNR) and spectral ...

From Gladiators to Problem-Solvers: Connecting Conversations About Women, the Academy, and the Legal Profession [PDF]

, 1997
The UHF band between 470-790 MHz, currently occupied by digital ter- restrial TV (DTT) distribution in Europe, is widely regarded as a premium spectrum band for providing mobile coverage.

A targeted antiferromagnetic nanoprobe for ultra‐sensitive magnetic resonance imaging detection of sub‐millimeter esophageal tumors

BMEMat, EarlyView.
We developed a cyclo‐RGD peptide‐conjugated antiferromagnetic nanoparticle (RANP) as a targeted T1 contrast agent. Under 9 T MRI conditions, RANP exhibited an r1 value of 1.88 mM−1 s−1 and a low r2/r1 ratio of 1.84, enabling the detection of esophageal tumors as small as 0.8 mm in vivo. Abstract Early, non‐invasive detection of esophageal cancer at sub‐
