Advanced Science, EarlyView.Tooth decay progression transforms the dental pulp response from repair to fibrosis. At early stages, stromal cells reprogram to repair the extra cellular matrix (ECM), blood vessels, and nerves, remodel and grow, keeping repair possible. In advanced decay, hypoxia, and vessel regression, in complement with an immune switch, fuel nerve degeneration and

TRIPP: An Aperture Photometry Package for the Reduction of CCD Time Series Images
Open Astronomy, 2003 TRIPP is an aperture photometry program designed with the purpose of extracting light curves from large sets of similar CCD frames typically obtained during time-resolved photometric monitoring campaigns such as, for example, WET runs.

The MUCHFUSS photometric campaign
, 2018 Hot subdwarfs (sdO/Bs) are the helium-burning cores of red giants, which lost almost all of their hydrogen envelopes. This mass loss is often triggered by common envelope interactions with close stellar or even substellar companions. Cool companions like

The effect of photometric and geometric context on photometric and geometric lightness effects
Journal of Vision, 2014 We measured the lightness of probe tabs embedded at different orientations in various contextual images presented on a computer-controlled stereo display. Two background context planes met along a horizontal roof-like ridge. Each plane was a graphic rendering of a set of achromatic surfaces with the simulated illumination for each plane controlled ...

Two Novel S‐methyltransferases Confer Dimethylsulfide Production in Actinomycetota
Advanced Science, EarlyView.This study identifies two novel S‐adenosine‐methionine‐dependent methyltransferases, MddM1 and MddM2, in actinomycetes from the Mariana Trench. These enzymes can convert toxic hydrogen sulfide (H2S) and methanethiol (MeSH) into dimethylsulfide (DMS), serving as a cellular detoxification and oxidative stress response.

Ultraviolet Passbands for a Space Multicolor Photometric System
Open 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 ...

Astrocytic PERK Deficiency Drives Prefrontal Circuit Dysfunction and Depressive‐Like Behaviors
Advanced Science, EarlyView.Chen et al. show that the endoplasmic reticulum (ER) stress sensor PERK is downregulated in prefrontal cortex (PFC) astrocytes in major depressive disorder and in chronic‐stress mouse models. In young mice, astrocyte‐specific PERK loss reduces the synaptogenic cue thrombospondin‐1 (TSP1), leading to synaptic and circuit deficits and depressive‐like ...

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

Color Photometric Stereo Using Multi-Band Camera Constrained by Median Filter and Occluding Boundary
Journal of Imaging, 2019 One of the main problems faced by the photometric stereo method is that several measurements are required, as this method needs illumination from light sources from different directions.

Subicular Astrocytes Govern Seizure‐Impaired Fear Memory
Advanced Science, EarlyView.Astrocytes in dorsal subiculum act as a critical modulator of seizure‐associated cognitive dysfunction, operating through a Ca2+‐dependent adenosine‐linked astrocyte‐neuron signaling pathway that disrupts neuronal circuit homeostasis. This research highlights the potential of astrocyte‐targeted interventions as a therapeutic strategy, moving beyond the
