Special Issue on Fracture and Fatigue Assessments of Structural Components

open access: yesApplied Sciences, 2020
This Special Issue covers the broad topic of structural integrity of components subjected to either static or fatigue loading conditions, and it is concerned with the modelling, assessment and reliability of components of any scale. Dealing with fracture

"Notch-Off": a perspective on the termination of Notch signalling

open access: yesThe International Journal of Developmental Biology, 2009
During Notch mediated lateral inhibition, interacting cells establish or amplify differences in Notch signalling, which are then translated into distinct cell fate decisions according to the developmental context. In recent years, several mechanisms that increase the signalling capacity of interacting cells have been uncovered (reviewed in Bray, 2006 ...

Low‐Temperature Imidization of Polyimides (PI) for Scalable Manufacturing of Flexible Wearable Electronics

open access: yesAdvanced Engineering Materials, EarlyView.
Low‐temperature imidization of PEG‐modified polyimide enables fully screen‐printed, roll‐to‐roll fabrication of flexible electrodes on PET substrates, delivering robust mechanical durability and reliable ECG/EMG signal performance for wearable electronics.

Inhibition of Gamma-Secretase Promotes Axon Regeneration After a Complete Spinal Cord Injury

open access: yesFrontiers in Cell and Developmental Biology, 2020
In a recent study, we showed that GABA and baclofen (a GABAB receptor agonist) inhibit caspase activation and promote axon regeneration in descending neurons of the sea lamprey brainstem after a complete spinal cord injury (Romaus-Sanjurjo et al., 2018a).

Distinct Microstructural Characteristic Lengths Defining Notch Fatigue Crack Initiation and Propagation, and Defect Tolerance in Advanced Steels

open access: yesAdvanced Engineering Materials, EarlyView.
Schematic representation of modes of microcrack nucleation, growth and temporary arrestment at different boundaries, with the criteria for crack propagation in three scenarios: (1) large notch, (2) defect/small sharp notch, and (3) long crack. This work revisits and integrates results on the fatigue behavior of advanced bainitic steels (in particular ...

Fungal CSL transcription factors [PDF]

open access: yes, 2007
Background: The CSL (CBF1/RBP-J kappa/Suppressor of Hairless/LAG-1) transcription factor family members are well-known components of the transmembrane receptor Notch signaling pathway, which plays a critical role in metazoan development. They function as

Designing a Compact Microstrip Antenna Using the Machine Learning Approach

open access: yesJournal of Telecommunications and Information Technology, 2020
This paper presents how machine learning techniques may be applied in the process of designing a compact dual-band H-shaped rectangular microstrip antenna (RMSA) operating in 0.75–2.20 GHz and 3.0–3.44 GHz frequency ranges.

Enhanced Ultrasound Transmission Through Aberration Layers Using Space‐Coiling Acoustic Metamaterials

open access: yesAdvanced Engineering Materials, EarlyView.
Enhancing ultrasound transmission through an aberration layer exhibiting mismatched impedance with the surrounding medium possesses great implications in imaging and treatment. In this study, we show that a space‐coiling acoustic metamaterial with judiciously tailored structural profile can help improve impedance matching.

Glenoid Paralabral Cysts Causing Shoulder Pain and Isolated Infraspinatus Weakness: Early Arthroscopic Decompression and Labral Repair Leads to Complete Recovery: A Case Series

open access: yesJournal of Orthopaedic Case Reports
Introduction: Shoulder pain in young patients can be caused by various conditions such as tendinitis, bursitis, capsulitis, and labral tears. Superior labrum anterior to posterior (SLAP) tears can sometimes be associated with a paralabral cyst, which can
