We used quantitative sensory testing (QST) to gain further insight into mechanisms underlying pain in CRPS 1. Specific goals were: (1) to identify altered patterns of sensory processing some 8 years after diagnosis, (2) to document differences in sensory processing between 'warm' and 'cold' diagnostic subgroups, (3) to determine relationships between changed sensory processing and disease progr...

Pulse-controlled non-adiabatic quantum state transmission (QST) was proposed many years ago. However, in practice environmental noise inevitably damages communication quality the proposal. In this paper, we study optimally controlled QST presence of noise. By using Adam algorithm, find that optimal pulse sequence can dramatically enhance fidelity such an open system. comparison with idealized a...

Historically, laboratory pain research with children and adolescents has largely been conducted with healthy samples using the cold pressor task (CPT). Additional laboratory methodologies, commonly referred to as quantitative sensory testing (QST), include a variety of psychophysical tests assessing sensory perception (eg, pressure and heat tolerance) and sensory abnormalities. There is signifi...

Sensitization of the nervous system can present as pain hypersensitivity that may contribute to clinical pain. In spinal pain, however, the relationship between sensory hypersensitivity and clinical pain remains unclear. This systematic review examined the relationship between pain sensitivity measured via quantitative sensory testing (QST) and self-reported pain or pain-related disability in p...

We tested the hypothesis that vagal withdrawal plays a role in the rapid (phase I) cardiopulmonary response to exercise. To this aim, in five men (24.6+/-3.4 yr, 82.1+/-13.7 kg, maximal aerobic power 330+/-67 W), we determined beat-by-beat cardiac output (Q), oxygen delivery (QaO2), and breath-by-breath lung oxygen uptake (VO2) at light exercise (50 and 100 W) in normoxia and acute hypoxia (fra...

Abstract In the present work, we propose a generalization of confidence polytopes approach for quantum state tomography (QST) to case process (QPT). Our allows obtaining region in polytope form Choi matrix an unknown channel based on measurement results corresponding QPT experiment. The method uses improved version expression levels several positive operator-valued measures. We then demonstrate...

BACKGROUND Leg pain is associated with back pain in 25-65% of all cases and classified as somatic referred pain or radicular pain. However, distinction between the two may be difficult as different pathomechanisms may cause similar patterns of pain. Therefore a pathomechanism based classification system was proposed, with four distinct hierarchical and mutually exclusive categories: Neuropathic...

BACKGROUND The aim of the study was to analyse intraoral neurophysiological changes in patients with unilateral lingual nerve lesions as well as patients with Burning Mouth Syndrome (BMS) by applying a standardized Quantitative Sensory Testing (QST) protocol. METHODS The study included patients suffering from a peripheral lesion of the lingual nerve (n = 4), from BMS (n = 5) and healthy contr...

We propose a distributed Quantum State Tomography (QST) protocol, named Local Stochastic Factored Gradient Descent (Local SFGD), to learn the low-rank factor of density matrix over set local machines. QST is canonical procedure characterize state quantum system, which we formulate as stochastic non-convex smooth optimization problem. Physically, estimation helps characterizing amount noise intr...

BACKGROUND There is evidence that acupuncture activates different spinal and supraspinal antinociceptive systems, but the specific modulatory effects on the sensory system have not been systematically investigated. In this study, we evaluated the immediate effects of different types of acupuncture on thermal, mechanical, and vibratory sensory thresholds. METHODS Twenty-four healthy volunteers...
