Dyson Spheres on H–R Diagram

open access: yesUniverse
The construction of Dyson spheres, megastructures designed to capture the total radiative output of stars, can be one of the most compelling techno-signature scenarios for advanced extraterrestrial civilizations.

Synthesis and Characterization of Highly Conductive Cobalt Phthalocyanine‐Based Metal–Organic Framework

open access: yesAdvanced Electronic Materials, EarlyView.
A two‐dimensional (2D) layered material, CoPc‐MOF, with a cobalt phthalocyanine backbone as its structural unit, was successfully synthesized. CoPc‐MOF adopts a crystal structure analogous to a Lieb lattice, which is a type of Dirac material. CoPc‐MOF exhibits exceptionally high electrical conductivity for an organic semiconductor, which likely ...

Emergent Spectral Fluxes of Hot Jupiters: An Abrupt Rise in Dayside Brightness Temperature Under Strong Irradiation

open access: yesThe Astronomical Journal, 2023
We study the emergent spectral fluxes of transiting hot Jupiters, using secondary eclipses from Spitzer. To achieve a large and uniform sample, we have reanalyzed all secondary eclipses for all hot Jupiters observed by Spitzer at 3.6 and/or 4.5 μ m.

Deep Learning‐Assisted Coherent Raman Scattering Microscopy

open access: yesAdvanced Intelligent Discovery, EarlyView.
The analytical capabilities of coherent Raman scattering microscopy are augmented through deep learning integration. This synergistic paradigm improves fundamental performance via denoising, deconvolution, and hyperspectral unmixing. Concurrently, it enhances downstream image analysis including subcellular localization, virtual staining, and clinical ...

The use of liquid crystal adaptive optics devices in astronomy [PDF]

open access: yes, 1991
Images obtained from large astronomical telescopes are distorted and blurred by the effects of the atmosphere. In order to compensate for this, an adaptive optics system can be incorporated downstream from the telescope focus.

HerMES : SPIRE galaxy number counts at 250, 350, and 500 μm [PDF]

open access: yes, 2010
Emission at far-infrared wavelengths makes up a significant fraction of the total light detected from galaxies over the age of Universe. Herschel provides an opportunity for studying galaxies at the peak wavelength of their emission.

Advanced Experiment Design Strategies for Drug Development

open access: yesAdvanced Intelligent Discovery, EarlyView.
Wang et al. analyze 592 drug development studies published between 2020 and 2024 that applied design of experiments methodologies. The review surveys both classical and emerging approaches—including Bayesian optimization and active learning—and identifies a critical gap between advanced experimental strategies and their practical adoption in ...

Autonomous Observations in Antarctica with AMICA

open access: yesAdvances in Astronomy, 2010
The Antarctic Multiband Infrared Camera (AMICA) is a double channel camera operating in the 2–28 𝜇m infrared domain (KLMNQ bands) that will allow to characterize and exploit the exceptional advantages for Astronomy, expected from Dome C in Antarctica ...
