Shear-wave velocity ( ) is an important parameter used for site characterization in geotechnical engineering. However, dispersion curve inversion is challenging for most inversion methods due to its high non-linearity and mix-determined trait. In order to overcome these problems, in this study, a joint inversion strategy is proposed based on the particle swarm optimization (PSO) algorithm. The ...

Abstract Objective: Literature regarding the association between presence and persistence of subjective cognitive complaints (SCCs) impairments is inconsistent. Therefore, we examined whether SCCs status (no/non-persistent/persistent SCCs), predicted risk developing incident Mild Cognitive Impairment (MCI). Methods: Participants were dementia-free community-residing older adults. We assessed at...

Course Multiple aspirations of the right shoulder and both knee joints were attempted during the first 4 days; little fluid was obtained in spite of the continued presence of clinical signs of infection. Throughout the first week ofhospitalization, the patient remained toxic with a daily temperature of 103-104°F. On the seventh day arthrotomy of each affected joint was performed and drains were...

The majority of patients with osteoarthritis present to orthopaedic surgeons seeking relief of pain and associated restoration of function. Although our understanding of the physiology of pain has improved greatly over the last 25 years there remain a number of unexplained pain-related observations in patients with osteoarthritis. The understanding of pain in osteoarthritis, its modulation and ...

A method for sensor fault estimation in multiple-input multiple-output linear time varying systems is proposed in this paper. It is based on a new adaptive observer for joint estimation of states and sensor faults in a state-space formulation of the monitored system. The exponential convergence of the algorithm is proved under some persistent excitation condition. Copyright c ©2005 IFAC

OBJECTIVE To assess the role of obesity and metabolic dysfunctionality with knee osteoarthritis (OA), knee joint pain, and physical functioning performance, adjusted for joint space width (JSW) asymmetry. METHODS Knee OA was defined as a Kellgren/Lawrence score > or =2 on weight-bearing radiographs. Obesity was defined as a body mass index > or =30 kg/m2. Cardiometabolic clustering classifica...

In 1890, Themistocles Gluck performed the first total wrist replacement, implanting an ivory ball-and-socket prosthesis in a 19-year-old male patient with tuberculosis. Although Gluck’s first patients suffered from persistent infection, his subsequent patients demonstrated good long-term results. Despite initial successes, the use of wrist arthroplasty has made slow progress within the orthopae...

OBJECTIVE The aim of this analysis is to examine the longitudinal impact of symptoms of depression/anxiety on treatment response, long-term disease activity and physical disability in RA. METHODS Secondary analysis of clinical trial data was performed. Data were collected at baseline and at 6-monthly intervals for 2 years. The EuroQoL (EQ-5D(TM)) indicated depression/anxiety symptom severity....
