Seismic analysis and design of tunnels within fault ground: A review

Deep Underground Science and Engineering, EarlyView.
The research methods of seismic response of tunnels within fault ground, including field investigations, analytical solutions, physical experiments, and numerical simulations, and seismic countermeasures are discussed. The present study examines the shortcomings and limitations of the current research and design, and puts forward proposals for future ...

Whole‐House Thermal Bridge Modelling for Accurate Retrofit Energy Prediction

Energy Science &Engineering, EarlyView.
This study models thermal bridging in a UK semi‐detached house across pre‐ and post‐retrofit scenarios using piecemeal and whole‐house approaches with EWI and IWI. Whole‐house retrofits reduce heat transfer coefficient by 60%; findings demonstrate that default values are often unrepresentative and advocate tailored Ψ value databases.

Fire Spread Characteristics of Cavities in Modular Constructions and Ventilated Facades

Fire and Materials, EarlyView.
ABSTRACT Modular buildings have gained popularity as a sustainable building solution. However, the uncertainty of fire spread through vertical cavity spaces in such buildings has become a concern. Therefore, this study aims to fill the gap in fire behaviour within vertical cavity spaces.

Phenotypic and Genotypic Analysis of Two Rare Cases of ‐‐SEA/‐α4.3 HbH Disease

Journal of Clinical Laboratory Analysis, EarlyView.
We report two unrelated adult patients with rare deletional HbH disease (genotype ‐‐SEA/‐α4.3). This novel 4.3 kb deletion covering the HBA1 gene is accompanied by X‐Y‐Z segment recombination, which was identified by CycloneSEQ long‐read nanopore sequencing.

3D Printing a Clinically Available Solution From Plaster‐Based Positives in Superficial Radiation Therapy

Journal of Medical Radiation Sciences, EarlyView.
This study compares two techniques for creating lead shielding masks to replace the current process for superficial/orthovoltage facial radiotherapy: Plaster Cast Positive Mould (PCPM), CT Scanned 3D Print (CT3DP), and Optical Scan 3D Print (OS3DP). CT3DP was found to be more accurate and preferred over OS3DP.
