Deep Learning-Based Prediction Algorithm on Atmospheric Turbulence-Induced Wavefront for Adaptive Optics

open access: yesIEEE Photonics Journal, 2022
Correction performance of an adaptive optics (AO) system is severely limited by its system latency under high temporal frequency distortions. Wavefront prediction methods has been proven to be an effective way to compensate system delay.

Time pressure reduces misinformation discrimination ability but does not alter response bias

open access: yesScientific Reports, 2022
Many parts of our social lives are speeding up, a process known as social acceleration. How social acceleration impacts people’s ability to judge the veracity of online news, and ultimately the spread of misinformation, is largely unknown.

The impact of CTLA-4 blockade and interferon-α on clonality of T-cell repertoire in the tumor microenvironment and peripheral blood of metastatic melanoma patients

open access: yesOncoImmunology, 2019
Patients with metastatic melanoma were treated with tremelimumab and interferon-α (IFN) in a previously reported clinical trial [NCT00610857]. Responses were assessed by RECIST criteria as complete (CR) or partial (PR), stable disease (SD) or progressive

Adaptivity and adaptation

open access: yesProceedings of the International Conference on Networked Learning, 2008
Within the iClass (Integrated Project n° 507922) and Elektra (Strep n°027986) European projects, the authors were requested to harness their pedagogical knowledge to the production of educational adaptive systems. The paper pinpoints and documents difficulties and limitations of this work as well as the possible fertility of such kind of ...

Design and Experimental Validation of a Model-Free Controller for Beam Stabilization in Adaptive Optics Systems

open access: yesIEEE Photonics Journal
Stabilization of optical beams has always been a key factor affecting the performance of many optical systems. The Adaptive optics (AO) beam stabilization system requires further development to cope with increasingly complex application scenarios and ...

Optimization of Iterative Control Algorithms for High-Resolution Adaptive Optics Systems

open access: yesIEEE Photonics Journal
As the number of wavefront sensor subapertures and deformable mirror actuators in adaptive optics systems increases, the computational time of the direct gradient wavefront control algorithm is excessively long, which is a major factor affecting the ...

Adaptive Metrics for Adaptive Samples [PDF]

open access: yesAlgorithms, 2020
We generalize the local-feature size definition of adaptive sampling used in surface reconstruction to relate it to an alternative metric on Euclidean space. In the new metric, adaptive samples become uniform samples, making it simpler both to give adaptive sampling versions of homological inference results and to prove topological guarantees using the

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Preliminary diagnosis of eye health via wavefront parameters based on statistical frequency distributions

open access: yesEuropean Journal of Medical Research
Background Eye disease is a global health issue, and current diagnostic methods are complex, costly and more suitable for final diagnosis. In order to detect abnormal eyes earlier, it is necessary to develop a simple and low-cost method for preliminary ...
