Time-lapse high-resolution microscopy to study the morphogenesis of microorganisms

Mélanie Thérèse Marie Hannebelle

Mycobacterium tuberculosis, the etiological agent for the tuberculosis disease, is a bacterial pathogen thought to infect about a quarter of the global human population. It is the first cause of death among infectious diseases, and is most prevalent in low ...

Kernel Modeling Super-Resolution on Real Low-Resolution Images

Sabine Süsstrunk, Ruofan Zhou

Deep convolutional neural networks (CNNs), trained on corresponding pairs of high- and low-resolution images, achieve state-of-the-art performance in single-image super- resolution and surpass previous signal-processing based approaches. However, their per ...

Scanning near-field optical microscopy with new probes and feedback modes

Anton Smirnov

Scanning Near-field Optical Microscopy (SNOM) technique enables to overcome Abbe diffraction limit of far-field optics as well as to obtain simultaneously optical and topographical images. While the optical resolution of the method is limited by the apertu ...

Closed-Form Expression of the Fourier Ring-Correlation for Single-Molecule Localization Microscopy

Michaël Unser, Daniel Sage, Thanh-An Michel Pham, Emmanuel Emilien Louis Soubies

Single-molecule localization microscopy (SMLM) is a popular microscopic technique that achieves super resolution imaging by localizing individual blinking molecules in thousands of frames. Therefore, the reconstructed high-resolution image is a combination ...

Transverse Detection of DNA Using a MoS2 Nanopore

Aleksandra Radenovic, Michael Graf, Martina Lihter, Sanjin Marion

Classical nanopore sensing relies on the measurement of the ion current passing through a nanopore. Whenever a molecule electrophoretically translocates through the narrow constriction, it modulates the ion current. Although this approach allows one to mea ...

Short spatial resolutions retrieval from a long pulse BOTDA trace

Luc Thévenaz, Simon Adrien Zaslawski, Zhisheng Yang, Sheng Wang

A novel technique is proposed to obtain a flexible and variable spatial resolution from a conventional Brillouin optical time-domain analyzers using a fast post-processing algorithm. The approach is very attractive since a fine spatial resolution can be ob ...

Overview and recommendations for regionalized life cycle impact assessment

Laurent Alexis Clément Vannay, Alexis Laurent, Xun Liao

Purpose Regionalized life cycle impact assessment (LCIA) has rapidly developed in the past decade, though its widespread application, robustness, and validity still face multiple challenges. Under the umbrella of UNEP/SETAC Life Cycle Initiative, a dedicat ...

A Nonsmooth Graph-Based Approach to Light Field Super-Resolution

Pascal Frossard, Mattia Rossi, Mireille El Gheche

In this article we propose a new super-resolution algorithm tailored for light field cameras, which suffer by design from a limited spatial resolution. To do so, we cast the light field super-resolution problem into an optimization problem, where the parti ...

Time-resolved Single-photon Detector Arrays for High Resolution Near-infrared Optical Tomography

Scott Anthony Lindner

Oxygenation is an important marker in many clinical settings, e.g. diagnosing ischaemic brain injuries in preterm infants or determining treatment effectiveness in cancer patients. Despite significant efforts to determine the oxygenation state of the human ...
