Beyond fragility: what the fragility index cannot measure
The fragility index reveals classification stability that p values conceal, but neither measure whether an observed result is geometrically separated from no effect, the point of therapeutic neutrality. Recent editorials in major journals have cataloged this limitation with unusual clarity, identifying sample-size dependence, p value correlation ...

Advanced 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,

Advanced Engineering Materials, EarlyView.This study examines how helicoidal architectures with different porosities respond to bending. Adjusting layer angle and spacing in 3D‐printed polymers reveals clear tradeoffs between stiffness, strength, and energy absorption. Experiments and simulations highlight designs that distribute stress effectively, offering pathways for optimizing lightweight

R code for Continuous Fragility Index
This R script calculates the Continuous Fragility Index (CFI) and Reverse CFI (RCFI) for two-group comparisons using Welch’s t-test. It includes functions for data generation, stepwise observation moves (greedy or closest‑mean strategies), and simulation

Advanced Engineering Materials, EarlyView.A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.

Mathematical incompleteness of the fragility index
Abstract Background The Fragility Index (FI) is intended to quantify how many outcome changes would be required to convert a statistically significant two-arm trial result into a non-significant one. For a metric defined on valid 2×2 trial tables, mathematical completeness means that a finite numeric value is obtainable for every valid
