L-Shaped Steel Collars: An Alternative External Confining Retrofit for Improving Ductility and Strength of Rectangular Concrete Columns [PDF]
Confinement in concrete column has been well known to improve its strength and ductility. Such enhancement is primarily essential when needed to improve the behavior of concrete columns particularly in terms of ductility during the earthquake strike ...

Compressive behaviour of CFRP-confined rectangular concrete columns
While there is abundant research on fibre reinforced polymer (FRP)-confined circular concrete columns, information on FRP-confined rectangular concrete columns is much more limited.

Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks
Advanced Science, EarlyView.Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,

Advanced Science, EarlyView.Multiferroic order parameters – polarization, magnetization, and ferroelastic strain – are positioned as dynamic design variables for batteries. Their mechanistic roles, practical tuning through fabrication and external fields, and ferroic‐resolved characterization routes are unified into a closed‐loop framework, revealing how coupled ferroic responses

Composite concrete columns of 3DP concrete and self-compacting concrete subjected to normal force [PDF]
Conventional concrete columns are cast in forms made of steel or wood. The work of erecting and dismantling the formwork is time-consuming and laborious. Steel forms can be used several times but wood forms are usually only used once or a small number of

Exact Discrete Stochastic Simulation With Deep‐Learning‐Scale Gradient Optimization
Advanced Science, EarlyView.A 203,796‐parameter gene regulatory network classifies handwritten digits with 98.4% accuracy using exact stochastic dynamics. The framework decouples forward simulation from backward differentiation, making continuous‐time Markov chain models compatible with deep‐learning optimization.

Electrically Tunable Piezotronic Transistor by Coupling Interface Polar Symmetry and Strain Gradient
Advanced Science, EarlyView.A macroscale tip‐induced strain gradient generates bulk piezo‐charges in GaN, enabling bias‐controlled shielding and selective Schottky barrier modulation. This strain‐gradient piezotronic transistor exhibits electrically switchable high‐ and low‐sensitivity states, providing ultrahigh strain sensitivity and wide tunability for adaptive mechanical ...
