Single‐Cell and Spatial Transcriptomics Unveil Key Regulators Governing Cell Differentiation for Schistosoma japonicum Sexual Development

open access: yesAdvanced Science, EarlyView.
Using single‐cell and spatial transcriptomics, we identified key regulators that govern cell differentiation involved in parasite development and egg laying in Schistosoma japonicum. This comprehensive study establishes a foundational resource for understanding schistosome biology, deciphers the regulatory programs underlying cell differentiation and ...

Ultrasound‐Recharged Sub‐Nanometer Palladium Catalysts for on‐Demand and Self‐Terminating Bioorthogonal Prodrug Activation in Cancer Therapy

open access: yesAdvanced Science, EarlyView.
Safe and precise bioorthogonal therapy of tumors was achieved by an ultrasound‐responsive heterostructured nanoreactor with on‐demand catalytic activity. Under piezoelectric catalysis, the system undergoes reversible Pd2+/Pd0 redox cycling, concurrently enabling spatiotemporally controlled prodrug activation and self‐terminating catalytic dose ...

Teen TITANS simulations

open access: yesAstronomy & Astrophysics
Young massive clusters (YMCs) are dense stellar systems that provide favorable environments for frequent stellar collisions, potentially leading to the formation of very massive stars (VMSs) and seeds of intermediate-mass black holes (IMBHs).

Cation Diffusion‐Mediated Displaced Reaction‐Transformation in Green Steelmaking

open access: yesAdvanced Science, EarlyView.
The removal of O lattice atoms by environmental H2 at the surface of Fe3O4 results in Fe enrichment, driving the inward diffusion of Fe cations into the bulk. Through hopping between unoccupied and initially occupied sites, cation diffusion triggers a spatially displaced reaction‐transformation and drives subsequent dynamic phase transformations and ...

From Young Massive Clusters to Old Globular Clusters: Density Profile Evolution and Intermediate-mass Black Hole Formation

open access: yesThe Astrophysical Journal
The surface brightness profiles of globular clusters are conventionally described with the well-known King profile. However, observations of young massive clusters (YMCs) in the local Universe suggest that they are better fit by simple models with flat ...

The photoevaporation of discs around young stars in massive clusters [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2007
We present models in which the photoevaporation of discs around young stars by an external ultraviolet source (as computed by Adams et al 2004) is coupled with the internal viscous evolution of the discs. These models are applied to the case of the Orion Nebula Cluster, where the presence of a strong ultraviolet field from the central OB stars ...

Dynamical Mass Estimates for Two Luminous Star Clusters in Galactic Merger Remnants [PDF]

open access: yes, 2006
We present high-dispersion spectra of two extremely massive star clusters in galactic merger remnants, obtained using the UVES spectrograph mounted on the ESO Very Large Telescope.

Gap‐Free Information Transfer in 4D‐STEM via Fusion of Complementary Scattering Channels

open access: yesAdvanced Science, EarlyView.
Fused Full‐Field STEM (FF‐STEM) is introduced as a 4D‐STEM imaging modality that combines direct ptychography with tilt‐corrected dark‐field reconstruction in a single acquisition. Fourier‐space fusion using Wiener‐type spectral weighting closes the low‐frequency contrast gap inherent to bright‐field methods, delivering gap‐free, dose‐efficient, near ...

ALMA-LEGUS. I. The Influence of Galaxy Morphology on Molecular Cloud Properties

open access: yesThe Astrophysical Journal
We present a comparative study of the molecular gas in two galaxies from the Legacy ExtraGalactic UV Survey (LEGUS) sample: barred spiral NGC 1313 and flocculent spiral NGC 7793.

Integration of Reconfigurable p‐Bit and 1R Crossbar Array for Memristive Probabilistic Computing

open access: yesAdvanced Science, EarlyView.
A memristive probabilistic computing system is demonstrated by integrating stochastic p‐bits based on volatile memristors with a 1R crossbar array encoding interaction weights. The system performs weighted‐sum operations across the array and updates p‐bits iteratively.
