Macropinocytic Uptake and pH‐Responsive Endolysosomal Processing Drive Sustained Chemotherapeutic Efficacy of High‐Load Core@Shell Nanocarriers in Colorectal Cancer

Small Science, Volume 6, Issue 1, January 2026.
This study develops core@shell nanocarriers with an exceptionally high chemotherapy drug payload, exhibiting strong cytotoxic effects. Using this adaptable nanocarrier‐synthesis platform, herein, the cellular uptake pathway and intracellular journey of the nanocarriers are elucidated with different probe‐based imaging strategies.

SMC-Last Extracted Photometry

The Astronomical Journal
We present point-source photometry from the Spitzer Space Telescope's final survey of the Small Magellanic Cloud (SMC). We mapped nearly 30 deg ^2 in two epochs in 2017, with the second extending to early 2018 at 3.6 and 4.5 μ m using the Infrared Array ...

The Spectral Energy Distributions and Bolometric Luminosities of Local AGN: Study of the Complete 12 μm AGN Sample

The Astrophysical Journal
We measure the bolometric luminosity of a complete and unbiased 12 μ m-selected sample of active galactic nuclei (AGN) in the local Universe. For each galaxy, we used a 10-band radio-to-X-ray spectral energy distribution (SED) to isolate the genuine AGN ...

Long-term infrared photometry of Seyferts [PDF]

Monthly Notices of the Royal Astronomical Society, 2004
Long-term (up to 10 000 d) monitoring has been undertaken for 41 Seyferts in the near-infrared (1.25–3.45 μm). All but two showed variability, with amplitudes at K in the range 1.1 mag. The time-scale for detectable change is from about one week to a few years.

Dazzle: Oversampled Image Reconstruction and Difference-imaging Photometry for the Nancy Grace Roman Space Telescope

The Astronomical Journal
We present algorithms and software for constructing high-precision difference images to detect and measure transients, such as microlensing events, in crowded stellar fields using the Nancy Grace Roman Space Telescope.

Infrared photometry of UV Piscium

Astrophysics and Space Science, 1987
The eclipsing binary system UV Psc was observed in the near-infrared (JHK), and a wave-like distortions have been observed similar to those in the visible. The out-of-eclipse observations have shown real large amount of scatter. This cannot be attributed to the existence of spots on one of the components, which can explain the wave-like distorition of ...

The Araucaria Project. The distance to the Sculptor group galaxy NGC 7793 from near-infrared photometry of Cepheid variables

EPJ Web of Conferences, 2017
We performed deep near-infrared J and K photometry of a field in the Sculptor Group spiral galaxy NGC 7793 using ESO VLT and HAWK-I instrument. We produced a sample of 14 Cepheids whose locations and periods of pulsation were known from our previous ...

From Earths to Super-Earths: Five New Small Planets Transiting M Dwarf Stars

The Astronomical Journal
Earth-sized planets transiting M dwarf stars present one of the best opportunities with current facilities for studying the atmospheric and bulk compositions of terrestrial worlds. Here, we statistically validate five new transiting Earth and super-Earth
