Environmental Toxicology, Volume 41, Issue 10, Page 1105-1118, October 2026.ABSTRACT Given the inevitability of human and animal exposure to acrylamide, there is increasing concern regarding its potential health risks. While a number of molecular mechanisms have been proposed, the complexity of acrylamide toxicological pathways and interactions remains incompletely characterized.

The cluster-galaxy cross spectrum
, 2008 Context. There are several wide field galaxy and cluster surveys planned for the near future, e.g. BOSS, WFMOS, ADEPT, Hetdex, SPT, eROSITA. In the simplest approach, one would analyze these independently, thus neglecting the extra information provided ...

The Shape of the Chameleon Fifth-Force on the Mass Components of Galaxy Clusters
UniverseIn the context of chameleon gravity, we present a semi-analytical solution of the chameleon field profile in an accurately modelled galaxy cluster’s mass components, namely the stellar mass of the Brightest Cluster Galaxy (BCG), the baryonic mass in ...

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.Abstract Bayesian inference methods such as Markov Chain Monte Carlo (MCMC) typically require repeated computations of the likelihood function, but in some scenarios, this is infeasible and alternative methods are needed. Simulation‐based inference methods address this problem by using machine learning to amortize computations.

A bright, dust-obscured, millimeter-selected galaxy beyond the bullet cluster (1E0657-56) [PDF]
, 2008 Deep 1.1 mm continuum observations of 1E0657-56 (the “Bullet Cluster”) taken with the millimeter-wavelength camera AzTEC on the 10-m Atacama Submillimeter Telescope Experiment (ASTE), have revealed an extremely bright (S1.1mm = 15.9 mJy) unresolved ...

Journal of Applied Crystallography, Volume 59, Issue 5, Page 1693-1706, October 2026.A low‐cost, portable, medium‐resolution polarizing digital light microscope device for monitoring crystal growth and for crystal harvesting is described. The device can be used with a cell phone or a personal computer for real‐time imaging by professional and amateur scientists alike.Motivated by the need for a convenient way to demonstrate the growth ...

Molecular gas and dust in the highly magnified z ∼2.8 galaxy behind the Bullet Cluster [PDF]
, 2012 Context. The gravitational magnification provided by massive galaxy clusters makes it possible to probe the physical conditions in distant galaxies that are of lower luminosity than those in blank fields and likely more representative of the bulk of the ...
