Channel Estimation for Massive MIMO-OFDM Systems by Tracking the Joint Angle-Delay Subspace [PDF]
, 2016 In this paper, we propose joint angle-delay subspace based channel estimation in single cell for broadband massive multiple-input and multiple-output (MIMO) systems employing orthogonal frequency division multiplexing (OFDM) modulation.

Acoustic Measures Capture Speech Dysfunction in Spinocerebellar Ataxia
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Spinocerebellar ataxias (SCA) are hereditary cerebellar degenerative disorders with a common feature of dysarthria, involving impaired phonatory and articulatory control of speech, thereby affecting social communication. In this study, we investigated whether acoustic measures could objectively measure speech dysfunction and identify

Encoderless Gimbal Calibration of Dynamic Multi-Camera Clusters
, 2018 Dynamic Camera Clusters (DCCs) are multi-camera systems where one or more cameras are mounted on actuated mechanisms such as a gimbal. Existing methods for DCC calibration rely on joint angle measurements to resolve the time-varying transformation ...

Functional Fusion Angle for Thumb Interphalangeal Joint Arthrodesis [PDF]
HAND, 2016 Background: A thumb interphalangeal (IP) joint arthrodesis is typically performed in 0° to 30° of flexion; most daily activities involve increased flexion at the IP joint to facilitate pinch and grip. This study evaluates the preferred thumb IP joint position with certain tasks of daily living to determine a more satisfactory angle.

Association of Corticospinal Tract Asymmetry With Ambulatory Ability After Intracerebral Hemorrhage
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Ambulatory ability after intracerebral hemorrhage (ICH) is important to patients. We tested whether asymmetry between ipsi‐ and contra‐lesional corticospinal tracts (CSTs) assessed by diffusion tensor imaging (DTI) is associated with post‐ICH ambulation.

Cycle-to-cycle control of swing phase of paraplegic gait induced by surface electrical stimulation [PDF]
, 1995 Parameterised swing phase of gait in paraplegics was obtained using surface electrical stimulation of the hip flexors, hamstrings and quadriceps; the hip flexors were stimulated to obtain a desired hip angle range, the hamstrings to provide foot ...
