Parvalbumin Interneuron‐Dependent Hippocampal Neurogenesis Evoked by Prolonged Rhythmic Light Flicker

open access: yesAdvanced Science, EarlyView.
This study demonstrates that prolonged rhythmic 40 Hz light flicker enhances spatial learning by stimulating PV interneuron‐dependent neurogenesis. The light flicker selectively activates PV interneurons, which enhances GABAergic support for the integration of immature neurons in the adult dentate gyrus.

Mesenchymal Stromal Cells Play an Analgesic Role Through a Npy2r Sensory Neuron‐Mediated Lung‐to‐Brain Axis

open access: yesAdvanced Science, EarlyView.
Mesenchymal stromal cells (MSC) are considered a promising alternative for neuropathic pain (NP) treatment, but underlying mechanisms remain elusive. Huang et al. illustrate that a Npy2r sensory neuron‐related lung–brain axis contributes to MSC analgesia.

Ultraviolet Passbands for a Space Multicolor Photometric System

open access: yesOpen Astronomy, 2003
The results of search for the optimal location of ultraviolet passbands for an extra-atmospheric photometric system are given. The addition of passbands near the well-known extinction bump at 218 nm to the photometric system makes it possible to ...

Deep Photometric Stereo Network with Multi-Scale Feature Aggregation

open access: yesSensors, 2020
We present photometric stereo algorithms robust to non-Lambertian reflection, which are based on a convolutional neural network in which surface normals of objects with complex geometry and surface reflectance are estimated from a given set of an ...

Viral‐Directed Augmentation of Kupffer Cell Cross‐Presentation Provokes Antitumor Immunity Against Liver Metastasis

open access: yesAdvanced Science, EarlyView.
Targeting Kupffer cells (KC) with a single intravenous infusion of the oncolytic virus VSV‐M51R rather than VSV‐WT induces effective tumor regression in various types of liver metastatic cancers in mice. VSV‐M51R promotes KC proliferation and enhances their antigen cross‐presentation capacity without compromising viability, leading to the induction of ...

Interstellar Extinction in the Direction of The Barnard 1 Dark Cloud in Perseus

open access: yesOpen Astronomy, 2003
Spectral and luminosity classes, absolute magnitudes, color excesses, interstellar extinctions and distances are determined for 98 stars down to 18 mag in the Barnard 1 dark cloud belonging to the Per OB2 association. The classification of stars is based

PHOTOMETRIC STEREO SHAPE-AND-ALBEDO-FROM-SHADING FOR PIXEL-LEVEL RESOLUTION LUNAR SURFACE RECONSTRUCTION [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
Shape and Albedo from Shading (SAfS) techniques recover pixel-wise surface details based on the relationship between terrain slopes, illumination and imaging geometry, and the energy response (i.e., image intensity) captured by the sensing system ...
