Regional Adjustments to NGA‐West2 Ground‐Motion Models for Turkey

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This paper presents a ground‐motion model updating (GMMU) framework to adjust NGA‐West2 models for predicting a set of intensity measures in Turkey, including peak ground acceleration (PGA), peak ground velocity (PGV), and pseudo‐spectral acceleration (PSA) at periods ranging from 0.01 to 10 s. The GMMU framework integrates bias identification

Evaluation of Modeling Assumptions for Predicting Structural Damage and Train Derailment Under Earthquake Loading

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT The rapid development of new railway networks and the aging of existing infrastructure in seismic‐prone regions continue to motivate the need for efficient methods to simulate the dynamic behavior of coupled train track structure systems. While detailed train–structure interaction (TSI) models can capture complex mechanisms, they are often too

Seismic Fragility Analysis of Containment Structures in Nuclear Power Plants Considering Alkali‐Silica Reaction

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This study quantifies the influence of alkali‐silica reaction (ASR) on the seismic fragility of prestressed concrete containment structures in nuclear power plants (NPPs). Global collapse was considered as the governing failure mode to maintain consistency with current risk assessment frameworks, and was captured using a finite element model ...

Three‐Dimensional Analytical Model of a Free‐Standing Square Rocking Column

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT A three‐dimensional analytical two‐degree‐of‐freedom (2DOF) model is developed to describe the bounded rocking response of free‐standing rigid square columns subjected to bidirectional seismic excitation. The formulation extends Housner's classical planar theory by deriving the full three‐dimensional equations of motion for a column ...

Magnetocardiography combined with machine learning for pulmonary hypertension detection and improved short‐term risk assessment

Interdisciplinary Medicine, EarlyView.
Magnetocardiography (MCG) enables non‐invasive mapping of cardiac magnetic fields. In this study, an MCG‐based machine learning model detects pulmonary hypertension with robust performance. Furthermore, MCG features may improve the accuracy of short‐term risk assessment.

The influence of flap design on the relevance of biomaterials in regenerative periodontal surgery

Journal of Periodontology, EarlyView.
Abstract Background The aim of this systematic review was to explore whether the benefits of biomaterials in periodontal regenerative/reconstructive surgery are affected by the type of flap employed. The study addresses the existing gap in the evidence to substantiate the beneficial effect of minimal invasive periodontal surgical approach compared to a

Microbial γ-polyglutamic acid (γ-PGA) incorporation into muffins: Impact on physico-chemical, functional, and textural properties

Frontiers in Food Science and Technology
This study investigated the effects of gamma‐(γ)‐polyglutamic acid (γ‐PGA) on the physical, structural, and sensory properties of muffins. γ‐PGA polymer, extracted from Bacillus valezensis M‐E6, was incorporated into muffin batter at concentrations ...

Effects of Polyvalent Cations on FTIR Spectra of Organic Matter–Cation Associations

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background The composition of soil organic matter (SOM) can be characterized by functional groups in the organic matter (OM). The carboxylic acid and carboxylate groups of OM show specific absorption bands in Fourier‐transform infrared (FTIR) spectra. However, cation–OM interactions may affect absorption bands and limit spectral interpretation
