The Study of the Sensitivity of GTN Parameters

Procedia Structural Integrity, 2020
Abstract Gurson–Tvergaard–Needleman (GTN) model is a quite reliable tool that we can use to predict the failure of a component. Still, the determination of those parameters is not an easy task. It takes much time for computing, and sometimes we do find different sets of GTN parameters, with the same results after simulation. The purpose of this paper

Intracranial Bleeding After Reperfusion Therapy in Acute Ischaemic Stroke Patients Randomized to Glyceryl Trinitrate vs. Control: An Individual Patient Data Meta-Analysis

Frontiers in Neurology, 2020
Background: Thrombolysis, with or without thrombectomy, for acute ischaemic stroke is associated with an increased risk of intracranial bleeding. We assessed whether treatment with glyceryl trinitrate (GTN), a nitric oxide donor, may influence the ...

Crack initiation and propagation in small-scale yielding using a nonlocal GTN model

, 2020
This study aims at investigating a non-local Gurson-Tvergaard-Needleman (GTN) ductile damage model at finite strains within the framework of small-scale yielding. This model solves the problems of spurious strain localization and volumetric locking.

DPP4 Regulates DHCR24-Mediated Cholesterol Biosynthesis to Promote Methotrexate Resistance in Gestational Trophoblastic Neoplastic Cells

Frontiers in Oncology, 2021
Metabolic reprogramming could promote cellular adaptation in response to chemotherapeutic drugs in cancer cells. Herein, we aimed to characterize the metabolomic profiles regulated by Dipeptidyl Peptidase 4 (DPP4) in methotrexate (MTX)-resistant ...

The Role of Methotrexate Chemotherapy in Impeding Rupture - Low-Risk Gestational Trophoblastic Neoplasia Management: A Case Report

Obgynia
Background: Gestational Trophoblastic Neoplasia (GTN) is a type of malignant growth that originates from abnormal proliferation of placental trophoblast. GTN can even be cured in its metastatic forms with a high success rate of 90-100%.

A New Implementation of Network GARCH Model for Stock Volatility and Co‐Volatility Forecasting

Journal of Forecasting, EarlyView.
ABSTRACT Volatility clustering and spillovers are key features of financial time series with many cross‐sectional assets. While network analysis links similar or correlated stocks and helps trace volatility spillovers, contemporary multivariate ARCH‐GARCH formulations struggle to represent structured network dependence and remain parsimonious.
