Shot noise and conductivity at high bias in bilayer graphene: Signatures of electron-optical phonon coupling [PDF]

open access: yes, 2011
We have studied electronic conductivity and shot noise of bilayer graphene (BLG) sheets at high bias voltages and low bath temperature $T_0=4.2$ K. As a function of bias, we find initially an increase of the differential conductivity, which we attribute ...

Reconciling modern machine-learning practice and the classical bias–variance trade-off [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2018
Significance While breakthroughs in machine learning and artificial intelligence are changing society, our fundamental understanding has lagged behind. It is traditionally believed that fitting models to the training data exactly is to be avoided as it ...

Pocket hematoma after pacemaker or defibrillator surgery: Direct oral anticoagulants versus vitamin K antagonists

open access: yesInternational Journal of Cardiology: Heart & Vasculature, 2022
Background: Direct oral anticoagulants (DOACs) are the preferred choice of oral anticoagulation in patients with atrial fibrillation (AF). Randomized trials have demonstrated the efficacy and safety of DOAC in patients undergoing a cardiac implantable ...

Gender Bias in Nobel Prizes [PDF]

open access: yes, 2018
Strikingly few Nobel laureates within medicine, natural and social sciences are women. Although it is obvious that there are fewer women researchers within these fields, does this gender ratio still fully account for the low number of female Nobel ...

Influence of Magnesium on Spatter Behavior in Laser Deep Penetration Welding of Aluminum Alloys

open access: yesJournal of Manufacturing and Materials Processing, 2019
The quality of welds, as well as the necessity of post-processing, is challenged by spatter generation during the laser keyhole welding process. In this study, the influence of the magnesium content on spatter behavior is studied for three aluminum ...

Extended-Aperture Shape Measurements Using Spatially Partially Coherent Illumination (ExASPICE)

open access: yesSensors
We have recently demonstrated that the 3D shape of micro-parts can be measured using LED illumination based on speckle contrast evaluation in the recently developed SPICE profilometry (shape measurements based on imaging with spatially partially coherent
