High ice water content at low radar reflectivity near deep convection – Part 2: Evaluation of microphysical pathways in updraft parcel simulations [PDF]

open access: yesAtmospheric Chemistry and Physics, 2015
The aeronautics industry has established that a threat to aircraft is posed by atmospheric conditions of substantial ice water content (IWC) where equivalent radar reflectivity (Ze) does not exceed 20–30 dBZ and supercooled water is not present ...

Protocol for quantifying miRNA trafficking across the endosomal membrane

open access: yesFEBS Open Bio, EarlyView.
An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

Rationally engineered polymeric interfaces for selective and dynamic recognition of vesicular agents

open access: yesFEBS Open Bio, EarlyView.
This review explores how molecularly imprinted polymers can be engineered to recognize complex nanoscale vesicles, including extracellular vesicles and membrane‐enveloped viruses. By tailoring polymer cavities to vesicle surface chemistry and structure, these synthetic receptors support selective detection, separation, and integration with optical ...

Dissolution of a Carbon Dioxide Bubble in a Vertical Pipe

open access: yesJournal of Fluid Science and Technology, 2008
Dissolution of single carbon dioxide (CO2) bubbles in a vertical pipe of 25 mm diameter is measured to examine the effects of the ratio λ of the sphere-volume equivalent bubble diameter to the pipe diameter, the liquid Reynolds number and ...

[P014] Influence of image truncation on the calculation of water equivalent diameter in computed tomography examinations

open access: yesPhysica Medica, 2018
Purpose Evaluate the effect of image truncation on the calculation of Water Equivalent Diameter (WED) for chest and abdomen Computed Tomography (CT) examinations. Correction factors for WED to rectify for the missing information were investigated. Methods Two clinical sets of 286 chest and 222 abdomen CT examinations for which the middle axial ...

Potential effect of human chorionic gonadotropin‐induced extracellular vesicle RNAs on mouse ovarian granulosa cells

open access: yesFEBS Open Bio, EarlyView.
To mimic the LH action in the ovary, granulosa‐cell and mouse models were stimulated by hCG, which changed RNA profiles within extracellular vesicles (EVs), and potentially hCG‐responsive EV RNAs increased the number of recipient ovarian cells. EV‐associated RNAs are potential intermediaries of hCG signaling.

Vertical upward flow patterns in small diameter tubes [PDF]

open access: yes, 2005
Two-phase flow patterns were studied in vertical small diameter tubes using R134a as the working fluid. The observed flow patterns include bubbly, dispersed bubble, confined bubble, slug, churn, annular and mist flow.

A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

open access: yesAdvanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,
