Imaging three-dimensional polarization in epitaxial polydomain ferroelectric thin films

open access: yes, 2002
Voltage-modulated scanning force microscopy (Piezoresponse microscopy) is applied to investigate the domain structure in epitaxial PbZr0.2Ti0.8O3 ferroelectric thin films grown on (001) SrTiO3.

Measuring every particle's size from three-dimensional imaging experiments

open access: yes, 2012
Often experimentalists study colloidal suspensions that are nominally monodisperse. In reality these samples have a polydispersity of 4-10%. At the level of an individual particle, the consequences of this polydispersity are unknown as it is difficult to

B cell mechanobiology in health and disease: emerging techniques and insights into therapeutic responses

open access: yesFEBS Letters, EarlyView.
B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...

Influence of Connecting Two Standalone Mobile Three-Dimensional Scanners on Accuracy Comparing with a Standard Device in Facial Scanning

open access: yeseJournal of Oral Maxillofacial Research, 2017
Objectives: In this study is investigated if bundling of two scanners leads to better accuracy in recording faces than a standard face-scanning device. Material and Methods: In a group of 28 volunteers, two test specimens were attached to their faces:

Applicability test for reducing noise on PET dynamic images using phantom applying deep image prior [PDF]

open access: yesarXiv, 2023
Objective Positron emission tomography (PET) allows imaging of patho-physiological information as a form of rate constants from a dynamic image. The rate constant image(s) may be affected from noise on the dynamic image. We introduced an artificial intelligence technique of deep image prior (DIP) to reduce noise on dynamic images.

Three-dimensional imaging of random radiation sources [PDF]

open access: yes, 1996
A method to image random three-dimensional source distributions is proposed. We show that, by using a Michelson stellar interferometer in a prescribed fashion, one is able to measure a special form of a three-dimensional degree of coherence.

Evolutionary interplay between viruses and R‐loops

open access: yesFEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Synthesizing brain tumor images and annotations by combining progressive growing GAN and SPADE [PDF]

open access: yesarXiv, 2020
Training segmentation networks requires large annotated datasets, but manual annotation is time consuming and costly. We here investigate if the combination of a noise-to-image GAN and an image-to-image GAN can be used to synthesize realistic brain tumor images as well as the corresponding tumor annotations (labels), to substantially increase the ...

Multiplexed and scalable super-resolution imaging of three-dimensional protein localization in size-adjustable tissues

open access: yesNature Biotechnology, 2016
The biology of multicellular organisms is coordinated across multiple size scales, from the subnanoscale of molecules to the macroscale, tissue-wide interconnectivity of cell populations.
