Comparing methods of detecting and segmenting unruptured intracranial aneurysms on TOF-MRAS: The ADAM challenge

open access: yesNeuroImage, 2021
Accurate detection and quantification of unruptured intracranial aneurysms (UIAs) is important for rupture risk assessment and to allow an informed treatment decision to be made.

High-frequency issues using rotating voltage injections intended for position self-sensing [PDF]

open access: yes, 2013
The rotor position is required in many control schemes in electrical drives. Replacing position sensors by machine self-sensing estimators increases reliability and reduces cost. Solutions based on tracking magnetic anisotropies through the monitoring of

Semiconducting Polymer Nanoparticles Enable Light‐Controlled Bidirectional Modulation of Nitric Oxide in Endothelial Cells

open access: yesAdvanced Science, EarlyView.
Bimodal modulation of nitric oxide in endothelial cells is achieved by light‐sensitive polymer nanoparticles. In dark, P3HT/PEDOT:PSS NPs boost intracellular ·NO, upregulate both endothelial and induced nitric oxide synthase, and drive a metabolic shift toward glycolysis.

Improving Regenerating Mode Operation of MRAS-Based Induction Motor Speed Estimation Using the Multilayer Technique

open access: yesIEEE Access
Model Reference Adaptive Systems (MRASs) are one of the most commonly applied techniques to estimate induction motor speed. They ensure simple and algorithmic way to obtain all necessary variables to create a sensorless drive, or to provide the estimated

Three Phase Induction Motor Drive: A Systematic Review on Dynamic Modeling, Parameter Estimation, and Control Schemes

open access: yesEnergies, 2022
An induction motor is generally used in industrial applications because it is reliable, robust, and low cost. Reliability is one of the essential parameters based on which the motor is selected, and the induction motor primarily comes into force.

Doubly Fed Induction Generator Wind Turbine Control Based on a Novel MRAS Observer [PDF]

open access: yesProceedings of the Third International Conference on Computing and Wireless Communication Systems, ICCWCS 2019, April 24-25, 2019, Faculty of Sciences, Ibn Tofaïl University -Kénitra- Morocco, 2019
This paper proposes a novel Doubly Fed Induction Generator (DFIG) control approach using an optimized set of observers. Firstly, an Adaptive Disturbance Rejection Scheme (ADRS) Model Reference Adaptive System (MRAS) observer is applied to estimate generator speed.

Price Premiums for Single‐Name and Compound‐Name Geographical Indications in Swiss Cheese Trade

open access: yesAgribusiness, EarlyView.
ABSTRACT Geographical indications (GIs) have become increasingly important in agri‐food markets, especially in Europe. For Swiss cheese imports and exports, we analyze whether GIs are associated with higher trade prices. We find that price premiums can be obtained for both exports and imports. However, this is only the case for cheeses with single name

Optimizing Diagnostic Accuracy of Clinical Red Flags in RASopathies

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT RASopathies are a group of genetic disorders caused by pathogenic variants in the RAS‐mitogen‐activated protein kinase (RAS–MAPK) signaling pathway, often presenting with congenital heart defects, craniofacial dysmorphisms, and developmental delays. To assess the diagnostic yield of genetic testing in patients with suspected RASopathies and to

The 9th International RASopathies Symposium

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The RASopathies are a group of congenital disorders with overlapping clinical manifestations that are caused by pathogenic germline or early somatic variants that result in the hyperactivation of the RAS/mitogen‐activated protein kinase (MAPK) signaling pathway.
