Article Synopsis
- Developing patient-specific finite element models for corneal surgery can enhance the implementation of biomechanical simulations, helping to meet clinical needs while minimizing computational time.
- The study introduces a new corneal multizone-based finite element model, applied to keratoconus-affected corneas, which examines stress and strain fields under different boundary conditions.
- Results indicated significant differences in stress outcomes based on boundary conditions and disease severity, with the displacements method providing faster computational times, suggesting multicore calculations could further expedite clinical applications.
Article Synopsis
- A biomechanical model of the cornea must factor in stress-free geometry to avoid inaccurate deformation results; incorrect estimations can lead to overstressed or understressed corneal conditions.
- This study compares two methods, Displacement and Pre-stress, for determining the stress-free and physiological geometries of the cornea, noting that both methods yielded similar results for physiological geometry but differed in efficiency for stress-free geometry, especially with disease severity.
- The Displacement method proved more cost-effective for computing stress-free geometries, highlighting its potential for developing precise and practical corneal biomechanical models in real-time clinical applications, particularly for conditions like keratoconus.
The use of composite materials has shown steady growth in recent years due to their excellent specific mechanical properties and the possibility to reduce the weight of vehicles without impairing their safety and comfort. Continuous fibre-reinforced thermoplastic composites (CFRTP) show dynamic, acoustic, and damping properties far superior to steel and can be recycled and repaired. Their excellent properties make CFRTP good candidates for anti-vibration and shock absorbing components, however, out-of-plane mechanical properties hinder the anchoring to the vehicle's body by means of bolted connections.

For this purpose, PBT samples reinforced with short, glass fibers of Ultradur material with 0%, 20%, and 50% in weight content were tested. Dynamic moduli showed an increment with glass fiber content showing a nonlinear behavior with the temperature.

Particularly important in urban regions, where these species have evolved to breed in man-made containers and feed nearly exclusively on human hosts, the threat of vector-borne disease has risen in recent decades due to the growth of cities, progression of climate change, and increase in globalization. While the dynamics of Aedes populations in urban settings have been well studied in relation to ecological features of the landscape, relatively less is known about the relationship between neighborhood socioeconomic status and Aedes infestation.
