Tailored Sample Mounting for Light-Sheet Fluorescence Microscopy of Clarified Specimens by Polydimethylsiloxane Casting

open access: yesFrontiers in Neuroanatomy, 2019
The combination of biological tissue clearing methods with light-sheet fluorescence microscopy (LSFM) allows acquiring images of specific biological structures of interest at whole organ scale and microscopic resolution.

Brain-wide neuron quantification toolkit reveals strong sexual dimorphism in the evolution of fear memory

open access: yesCell Reports, 2023
Summary: Fear responses are functionally adaptive behaviors that are strengthened as memories. Indeed, detailed knowledge of the neural circuitry modulating fear memory could be the turning point for the comprehension of this emotion and its pathological

Comment on: "Measuring a Photonic Qubit without Destroying It" [PDF]

open access: yes, 2004
Recently, Pryde et al reported the demonstration of a quantum non-demolition scheme for single-photon polarization states with linear optics and projective measurements [Phys. Rev. Lett. 92, 190402 (2004)]. Here, we argue that their interpretation of the

Quantitative neuroanatomy of all Purkinje cells with light sheet microscopy and high-throughput image analysis

open access: yesFrontiers in Neuroanatomy, 2015
Characterizing the cytoarchitecture of mammalian central nervous system on a brain-wide scale is becoming a compelling need in neuroscience. For example, realistic modeling of brain activity requires the definition of quantitative features of large ...

Quantifying the Sensitivity and Unclonability of Optical Physical Unclonable Functions

open access: yesAdvanced Photonics Research, 2023
Due to their unmatched entropy, complexity, and security level, optical physical unclonable functions (PUFs) currently receive a lot of interest in the literature.

Data on the target search by a single protein on DNA measured with ultrafast force-clamp spectroscopy

open access: yesData in Brief, 2019
The mechanism by which proteins are able to find small cognate sequences in the range from few to few tens of base pairs amongst the millions of non-specific chromosomal DNA has been puzzling researchers for decades.

A New Look at Linear (Non-?) Symplectic Ion Beam Optics in Magnets [PDF]

open access: yes, 2013
We take a new look at the details of symplectic motion in solenoid and bending magnets and rederive known (but not always well-known) facts. We start with a comparison of the general Lagrangian and Hamiltonian formalism of the harmonic oscillator and ...

Flexible Multi-Beam Light-Sheet Fluorescence Microscope for Live Imaging Without Striping Artifacts

open access: yesFrontiers in Neuroanatomy, 2019
The development of light-sheet fluorescence microscopy (LSFM) has greatly expanded the experimental capabilities in many biological and biomedical research fields, enabling for example live studies of murine and zebrafish neural activity or of cell ...

High density InAlAs/GaAlAs quantum dots for non-linear optics in microcavities [PDF]

open access: yes, 2012
Structural and optical properties of InAlAs/GaAlAs quantum dots grown by molecular beam epitaxy are studied using transmission electron microscopy, temperature- and time resolvedphotoluminescence.

Myosin V fluorescence imaging dataset for single-molecule localization and tracking

open access: yesData in Brief, 2019
Myosin-5B is one of three members of the myosin-5 family of actin-based molecular motors fundamental in recycling endosome trafficking and collective actin network dynamics. Through single-molecule motility assays, we recently demonstrated that myosin-5B
