Epidemiology of Acute Q Fever, Scrub Typhus, and Murine Typhus, and Identification of Their Clinical Characteristics Compared to Patients with Acute Febrile Illness in Southern Taiwan

Journal of the Formosan Medical Association, 2009
In Taiwan, acute Q fever, scrub typhus, and murine typhus (QSM diseases) are the most common rickettsioses, but their epidemiology and clinical characteristics have not been clarified. Diagnosis of these three diseases based on clinical manifestations is

Comparison of quantitative susceptibility mapping methods for iron-sensitive susceptibility imaging at 7T: An evaluation in healthy subjects and patients with Huntington's disease

NeuroImage, 2023
Quantitative susceptibility mapping (QSM) is a promising tool for investigating iron dysregulation in neurodegenerative diseases, including Huntington's disease (HD). Many diverse methods have been proposed to generate accurate and robust QSM images.

QSM based NOMA for Multi-User Wireless Communication [PDF]

2019 16th International Symposium on Wireless Communication Systems (ISWCS), 2019
In this study, a quadrature spatial modulation (QSM) based non-orthogonal multiple access (NOMA) for multiuser, named as NOMA-QSM, is proposed. The main idea of NOMA-QSM is to superimpose several constellation symbols to be transmitted simultaneously via some selected antenna indexes by distinguishing power domain.

Evaluation of iron deposition in brain basal ganglia of patients with Parkinson's disease using quantitative susceptibility mapping

European Journal of Radiology Open, 2019
Aim of the study: Parkinson's disease is associated with iron deposition in the brain. The QSM (quantitative susceptibility mapping) is more sensitive than T2-weighted imaging, T2* and R2.
