Numerical simulation and experimental investigation of ductile fracture in SPIF using modified GTN model

open access: yesMATEC Web of Conferences, 2015
Incremental sheet forming (ISF) is a relatively new flexible forming process with excellent adaptability to CNC milling machines due to the fact that it does not require any high capacity presses or dies of a specific shape and this makes the process ...

Evaluation of formability and fracture of pure titanium in incremental sheet forming [PDF]

open access: yes, 2017
A forming limit diagram (FLD) is commonly used as a useful means for characterizing the formability of sheet metal forming processes. In this study, the Nakajima test was used to construct the forming limit curve at necking (FLCN) and fracture (FLCF ...

Finite element simulation of rotary blanking based on a modified GTN damage model

open access: yes工程科学学报, 2016
Based on the GTN model,a modified GTN model applicable to compressive stress conditions was established by considering the effect of microvoid shear deformation on the loss of load-carrying capacity. The elastic-plastic constitutive model with the damage

Neuropeptide Y in the medial habenula alleviates migraine-like behaviors through the Y1 receptor

open access: yesThe Journal of Headache and Pain, 2023
Background Migraine is a highly disabling health burden with multiple symptoms; however, it remains undertreated because of an inadequate understanding of its neural mechanisms.

Combining serum peptide signatures with International Federation of Gynecology and Obstetrics (FIGO) risk score to predict the outcomes of patients with gestational trophoblastic neoplasia (GTN) after first-line chemotherapy

open access: yesFrontiers in Oncology, 2022
BackgroundGestational trophoblastic neoplasia (GTN) is a group of clinically rare tumors that develop in the uterus from placental tissue. Currently, its satisfactory curability derives from the timely and accurately classification and refined management

Orbit measures, random matrix theory and interlaced determinantal processes [PDF]

open access: yes, 2008
A connection between representation of compact groups and some invariant ensembles of Hermitian matrices is described. We focus on two types of invariant ensembles which extend the Gaussian and the Laguerre Unitary ensembles.

Multicyclic D‐Stereospecific Hydrolase Dimer With High Sustained Activity

open access: yesAngewandte Chemie International Edition, EarlyView.
Protein macrocyclization was applied to a thermally unstable D‐stereospecific hydrolase using in situ cyclization of proteins (INCYPRO). This site‐specific cross‐linking approach enhanced the resistance of the enzyme to heat and cosolvents.

Early detection of gestational trophoblastic neoplasia based on serial measurement of human chorionic gonadotrophin hormone in women with molar pregnancy

open access: yesInternational Journal of Preventive Medicine, 2020
Background: The majority of studies which investigate the predicted power of Human chorionic gonadotropin (hCG) levels to the occurrence of Gestational trophoblastic neoplasia (GTN) considered the effect of a single measurement of hCG or used classical ...

PAR2 activation in the dura causes acute behavioral responses and priming to glyceryl trinitrate in a mouse migraine model

open access: yesThe Journal of Headache and Pain, 2023
Background Migraine is a severely debilitating disorder that affects millions of people worldwide. Studies have indicated that activation of protease-activated receptor-2 (PAR2) in the dura mater causes headache responses in preclinical models.
