Playing Hard with Si: Challenges and Opportunities for New Materials in Radiation Therapy Dosimetry
Advanced Materials, EarlyView.Silicon has been a cornerstone material of radiation therapy dosimetry for many decades, providing somewhat unchallenged performance. However, there are caveats to its use, requiring complex designs and, often, correction factors to provide accurate measurements.

A Simple Technique for Predicting High-Redshift Galaxy Evolution
, 2015 We show that the ratio of galaxies' specific star formation rates (SSFRs) to their host halos' specific mass accretion rates (SMARs) strongly constrains how the galaxies' stellar masses, specific star formation rates, and host halo masses evolve over ...

The formation and cosmic evolution of dust in the early Universe: I. Dust sources
The Astronomy and Astrophysics ReviewDust-obscured star formation has dominated the cosmic history of star formation, since $$z \simeq 4$$ z ≃ 4 . However, the recent finding of significant amount of dust in galaxies out to $$z \simeq 8$$ z ≃ 8 has opened the new frontier of

Thermochromic Gires‐Tournois Resonators with Tellurium for Battery Thermal Runaway Warning
Advanced Materials, EarlyView.A thermochromic Gires‐Tournois (GT) resonator with a thin tellurium layer enables rapid, reversible, and untethered detection of battery surface temperature <80 °C. Exploiting tellurium's refractive index change driven by a thermally induced phase transition between solid and quasi‐liquid states, the GT resonator visualizes heat propagation, providing ...

On the Determination of Star Formation Rates in Evolving Galaxy Populations [PDF]
, 2000 The redshift dependence of the luminosity density in certain wavebands (e.g. UV and H-alpha) can be used to infer the history of star formation in the populations of galaxies producing this luminosity.

Simulating galaxy formation with the IllustrisTNG model [PDF]
, 2017 We introduce an updated physical model to simulate the formation and evolution of galaxies in cosmological, large-scale gravity+magnetohydrodynamical simulations with the moving mesh code AREPO.

Simulations of galaxy formation and evolution [PDF]
Astronomische Nachrichten, 2012 AbstractWe discuss recent results of hydrodynamical simulations of galaxy formation in a Λ Cold Dark Matter universe, focusing on galaxies of similar mass to the Milky Way, and with a variety of formation and merger histories. We investigate the present‐day properties of disks and spheroids, in terms of stellar ages, spatial structure and dynamics; as ...

Advanced Materials Technologies, EarlyView.A highly sensitive crack‐based piezoresistive strain sensor is developed using a biaxially pre‐stretched multi‐walled carbon nanotubes/Ecoflex composite and integrated with auxetic metamaterials. Biaxial pre‐stretching improves the sensitivity by 56% compared to the uniaxially pre‐stretched strain sensor.

The Romulus Cosmological Simulations: A Physical Approach to the Formation, Dynamics and Accretion Models of SMBHs [PDF]
, 2017 We present a novel implementation of supermassive black hole (SMBH) formation, dynamics, and accretion in the massively parallel tree+SPH code, ChaNGa. This approach improves the modeling of SMBHs in fully cosmological simulations, allowing for a more de-

Modelling the formation and evolution of star cluster populations in galaxy simulations [PDF]
, 2011 The formation and evolution of star cluster populations are related to the galactic environment. Cluster formation is governed by processes acting on galactic scales, and star cluster disruption is driven by the tidal field.
