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

Arthritis 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 ...

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Flow in a Low Specific Speed Centrifugal Pump Using PIV

Advances in Mechanical Engineering, 2013
The interflow plays important roles in centrifugal pump design. In order to study the effect of rotation and z -axis on internal flow, two-dimensional particle image velocimetry (PIV) measurements have been performed to measure the steady velocity field ...

A predictive model obtained by identification for the ultrasonic “equivalent” flow velocity at surface vicinity

Ultrasonics Sonochemistry, 2010
In the specific applications of surface cleaning and electrochemistry which consist of processes implanting surface irradiation by ultrasound, design of large-scale devices requires us to understand acoustic field distribution together with its quantification.

Nano-scale superhydrophobicity: suppression of protein adsorption and promotion of flow-induced detachment [PDF]

, 2008
Wall adsorption is a common problem in microfluidic devices, particularly when proteins are used. Here we show how superhydrophobic surfaces can be used to reduce protein adsorption and to promote desorption.

Laser Powder Bed Fusion of Alumina: Effects of Scanning Strategies on External and Internal Defects

Advanced Engineering Materials, EarlyView.
This study investigates how scanning strategies affect pure alumina in laser powder bed fusion. Linear 45° scanning yields uniform surfaces but high porosity, while the island‐concentric strategy provides higher density with through‐holes favorable for infiltration. Findings highlight pathways toward optimizing defect‐free alumina parts.
