Preclinical Efficacy and Safety Evaluation of a Novel Controlled‐Expansion ePTFE‐Covered TIPS Stent in a Swine Model

Portal Hypertension &Cirrhosis, EarlyView.
This preclinical study evaluated a novel controlled‐expansion expanded polytetrafluoroethylene (ePTFE)‐covered transjugular intrahepatic portosystemic shunt (TIPS) stent in 11 swine, demonstrating 100% technical success, excellent deployability, and durable 6‐month angiographic patency without thrombosis, migration, fracture, or device‐related toxicity.

Strut-and-tie models for deteriorated reinforced concrete half-joints

, 2018
A reinforced concrete half-joint bridge consists of suspended span dapped-end beams or a full-width deck supported on the nibs of abutments or adjacent beams.

Exploring the Use and Impact of Composite Materials in Robotics: A Systematic Review

Journal of Field Robotics, EarlyView.
ABSTRACT Lightweight and high‐strength materials are important in robotics, as structural design impacts efficiency, payload capacity, and energy consumption. Composite materials, with their superior stiffness‐to‐weight ratios and multifunctional properties, offer clear advantages over conventional metals and polymers.

Numerical analyses of two-pile caps considering lateral friction between the piles and soil

Revista IBRACON de Estruturas e Materiais, 2021
: Pile caps are structural elements used to transfer loads from the superstructure to a group of piles. The design of caps is normally based on analytical formulations, considering the strut and tie method. Through the advance of computational technology,

Impact of half‐joint failures on RC girder bridges: A robustness quantification study

Structural Concrete, EarlyView.
Abstract The robustness of bridge structures is critical to ensuring safety and service continuity, particularly in aging infrastructure exposed to degradation and unexpected loads. Reinforced concrete (RC) half‐joint bridges—widely built in Italy between the 1950s and 1970s—exhibit specific vulnerabilities due to inspection challenges, durability ...

Experimental results and limit load analysis by the strut-and-tie method (STM) in deep beams with notches and openings [PDF]

Revista IBRACON de Estruturas e Materiais
This article presents experimental results of eight non-aligned, non-geometrically symmetrical deep beams with notches and openings. The variables considered in the study were the presence of web reinforcement, and the geometry of the deep beams.

Experimental and theoretical investigation of longitudinal tunnel lining joints with confining reinforcement

Structural Concrete, EarlyView.
Abstract Precast reinforced concrete segmental linings are frequently used in modern tunneling. In these linings, the longitudinal joints typically have a reduced contact cross‐section and thus often govern the design, particularly in tunnels under high hydrostatic pressure or crossing squeezing or swelling ground with correspondingly high ...
