Robust Multichannel Detection of Mixtures Using Nuclear Quadrupole Resonance'

Nuclear quadrupole resonance (NQR) is a radio-frequency (RF) spectroscopic technique, able to detect the presence of many high explosives and narcotics. In practice, the weak NQR signal is often corrupted by strong RF interference (RFI); therefore, various multichannel detection algorithms have recently been proposed for NQR. However, these algorithms allow for only a single compound/polymorph, wh

Biomarkers of early chronic obstructive pulmonary disease (COPD) in smokers and former smokers. Protocol of a longitudinal study.

Chronic obstructive pulmonary disease (COPD) is an irreversible disease, diagnosed predominantly in smokers. COPD is currently the third leading cause of death worldwide. Far more than 15 % of smokers get COPD: in fact, most develop some amount of pulmonary impairment. Smoking-related COPD is associated with both acute exacerbations and is closely correlated to comorbidities, such as cardiovascula

Moore's Paradox and Epistemic Norms

Abstract in UndeterminedWhy does it strike us as absurd to believe that it is raining and that onedoesn’t believe that it is raining? Some argue that it strikes us as absurd because belief isnormative. The beliefs that it is raining and that one doesn’t believe that it is are, it issuggested, self-falsifying. But, so it is argued, it is essential to belief that beliefs oughtnot, among other things

Risk factors for medial meniscal pathology on knee MRI in older US adults: a multicentre prospective cohort study.

OBJECTIVES: Meniscal pathology in which the aetiology is often unclear is a frequent finding on knee MRI. This study investigates potential risk factors for medial meniscal lesions or extrusion in middle-aged and elderly persons. METHODS: Prospective cohort study using population-based subjects from Birmingham, Alabama and Iowa City, Iowa, USA (the Multicenter Osteoarthritis Study). 644 men and

Discriminating Depressive Patients and Patients with Somatoform Disorders by Means of the Beck Depression Inventory

Ninety-eight patients, 56 suffering according to DSM-IV of unipolar depression and 42 of somatoform disorders, were compared on the Beck Depression Inventory (BDI) total scale, the subscale of Somatic complaints and the Cognitive-affective subscale. A factor analysis performed on the total group revealed five factors used to determine new subscales: Depressed mood, Somatic manifestations, Loss of

Right coronary fistula and aneurysm draining to the right atrium.

Abstract In a 3-year-old boy, a continuous heart murmur was heard. The echocardiogram showed a dilated right coronary artery suggesting the existence of a coronary fistula. A more detailed echocardiogram when the patient was sedated revealed a fistula leading to a large aneurysm and further to the right atrium. The accidental dissection and thrombosis during the interventional heart catheterizatio
