The Hawaii Infrared Parallax Program. VI. The Fundamental Properties of 1000+ Ultracool Dwarfs and Planetary-mass Objects Using Optical to Mid-infrared Spectral Energy Distributions and Comparison to BT-Settl and ATMO 2020 Model Atmospheres

open access: yesThe Astrophysical Journal, 2023
We derive the bolometric luminosities ( L _bol ) of 865 field-age and 189 young ultracool dwarfs (spectral types M6–T9, including 40 new discoveries presented here) by directly integrating flux-calibrated optical to mid-infrared (MIR) spectral energy ...

Infrared photometry of z   1 3C quasars [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2000
We present JHKL' photometry of a complete sample of steep-spectrum radio-loud quasars from the revised 3CR catalogue in the redshift range 0.65 < z < 1.20. After correcting for contributions from emission lines and the host galaxies, we investigate their spectral energy distributions (SEDs) around 1 micron.

Dorsal Raphe VIP Neurons Are Critical for Survival‐Oriented Vigilance

open access: yesAdvanced Science, EarlyView.
DRNVIP neurons in mice and primates are strategically positioned to influence the central extended amygdala via feedback loops. They regulate the excitability of PKC‐δ neurons in the ovBNST and CeA through glutamate release. Their ablation heightens activity in these regions, disrupts active‐phase sleep architecture, enhances risk assessment behaviors ...

The THESEUS Space Mission and the Infrared Telescope Calibration Unit

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT The Transient High‐Energy Sky and Early Universe Surveyor (THESEUS) is an ESA M7 mission concept currently in Phase A, designed to exploit gamma‐ray bursts to probe the early Universe while advancing multi‐messenger and time‐domain astrophysics. To achieve its ambitious goals, THESEUS will combine wide‐band x‐ray and gamma‐ray monitors with an

Infrared Photometry of Be Stars [PDF]

open access: yesSymposium - International Astronomical Union, 1982
A photometric study of Be stars in the JHKL system is reported here. Early papers (see Feinstein and Marraco, 1980) about bright southern Be stars observed photoelectrically in the UBVRI system and in the Balmer-lines: Hα, Hβ and Hγ, permit us to derive several conclusions about their light variability, the amount of emission in the α and β indices ...

Ultra‐Fast and Economical Pre‐Breakdown Electrochemical Synthesis of Intrinsically Conductive Polymer Suspension for Production of Safe Lithium‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This paper presents a breakthrough pre‐breakdown electrochemical method for synthesizing polyNiMeOSalen suspensions, achieving an 83% yield and nanoscale dispersion ($1500/kg) and environmental impact (1.42 kg CO2eq/kg). We report a novel pre‐breakdown electrochemical synthesis method for producing polyNiMeOSalen suspensions with exceptional ...

TRP canonical 4 and/or 5 channel inhibition reduces aversion‐ and increases reward‐responding in chronically stressed mice

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Pharmacological inhibition of TRPC4 and/or TRPC5 channels reduces Pavlovian aversion memory in stressed mice and reduces amygdala reactivity to aversion in humans with depression. The aims of this mouse study were to improve understanding of these anxiolytic processes, determine whether there are corrective effects on ...

Deriving All‐Hour Aerosol Optical Depth Over China From Automated Visibility Observations

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract All‐hour aerosol monitoring remains challenging due to limited spatiotemporal coverage of current observational systems. Here we developed a machine‐learning based framework that derives 24‐hr aerosol optical depth (AOD) from automated visibility measurements.
