Measurement of Reference Bubble Velocity Vector for a Local 4 Sensor Probe Using Orthogonal High Speed Cameras

open access: yes, 2007
In recent years, there has been an increase in the level of interest shown in making flow rate measurements in multiphase flow. This in part has been brought about by the metering requirements of the oil and natural gas industries.

Evaluation of Digital Technologies for Home‐Based Assessment in People With Amyotrophic Lateral Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Digital technologies hold promise for transforming healthcare by enhancing personalized treatments and offer valuable opportunities to improve patient care. Here, we evaluated several novel, self‐administered, home‐based, digital endpoints for their association with corresponding conventional standard clinical measures (primary) in ...

Transport and deposition behaviour of model slurries in closed pipe flow [PDF]

open access: yes, 2013
Suspensions of solid particles are ubiquitous in nature and industry. From subaqueous and aeolian dunes and ripples to plug flow in the minerals engineering industry, the complexity of the fluid dynamics and interparticle interactions in multiphase flow

Responses of Macroinvertebrate Communities to Heterogeneity Among Typical Reaches in the Upper Yangtze River

open access: yesEcology and Evolution
Benthic macroinvertebrates are important indicators of river ecosystem health, and their spatial distribution is highly sensitive to environmental heterogeneity. In large mountainous rivers characterized by complex geomorphology and strong hydrodynamics,

Upper Cervical Cord Area as a Biomarker of Conversion to Secondary Progressive Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective This study assessed whether upper cervical cord area (UCCA) measured on routine brain MRI can serve as a biomarker of conversion to SPMS. Methods This is a single‐center retrospective cohort study of RRMS patients with cross‐sectional and longitudinal analyses of clinical and MRI data. Future SPMS converters were matched by age, sex,

The value of flow velocity alterations measured by carotid Doppler in the diagnosis of acute anterior ischemic stroke

open access: yesHong Kong Journal of Emergency Medicine
Background Acute ischemic stroke is a leading cause of mortality and long‐term disability. Conventional imaging methods like CT and MRI, while essential, are limited by cost, accessibility, and the need for patient transport.

Video velocity measurement: A two-stage flow velocity prediction method based on deep learning

open access: yesHydrology Research
Due to the uncertainty in output caused by environmental changes, significant discrepancies are expected between the surface flow velocities predicted using deep learning methods and the instantaneous flow velocities.

Cracking the Code: Which Ocular Symptoms Predict Dry Eye Signs? Insights From a Large International Sicca Registry

open access: yesArthritis Care &Research, EarlyView.
Objective The study aimed to identify symptom‐based predictors of dry eye disease (DED) signs in the Sjögren's International Collaborative Clinical Alliance (SICCA) cohort. Methods We performed a retrospective analysis examining 16 ocular symptoms (most graded 0–4) and artificial tear (AT) use (graded 0–3) as predictors of DED signs (abnormal ocular ...
