Reionization and Cosmology with 21 cm Fluctuations [PDF]

, 2009
Measurement of the spatial distribution of neutral hydrogen via the redshifted 21 cm line promises to revolutionize our knowledge of the epoch of reionization and the first galaxies, and may provide a powerful new tool for observational cosmology from ...

Effects of Antenna Beam Chromaticity on Redshifted 21~cm Power Spectrum and Implications for Hydrogen Epoch of Reionization Array

, 2016
Unaccounted for systematics from foregrounds and instruments can severely limit the sensitivity of current experiments from detecting redshifted 21~cm signals from the Epoch of Reionization (EoR).

EOR-1 and EOR-2 function in RMED/V neuron specification

microPublication biology, 2019
In a visual screen for genes that regulate the pattern of the juIs76[Punc-25GFP] marker, which labels four GABAergic RME neurons and 19 ventral cord D-type neurons (Huang et al., 2002), we isolated two mutants, eor-2(ju190) and eor-1(ju198) (Huang and Jin, 2019). In both eor-2(ju190) and eor-1(ju198) mutants, Punc-25GFP expression was almost completely

The EoR Sensitivity of the Murchison Widefield Array [PDF]

, 2012
Using the final 128 antenna locations of the Murchison Widefield Array (MWA), we calculate its sensitivity to the Epoch of Reionization (EoR) power spectrum of red- shifted 21 cm emission for a fiducial model and provide the tools to calculate the ...

Operando Investigation of Mechanochemically Synthesized Ni‐Based Metal–Organic Frameworks for Electrocatalytic Alcohol Oxidation [PDF]

ChemSusChem
A nickel‐based metal–organic framework (Ni‐MOF) with mixed N‐ and O‐donor linkers was synthesized via both mechanochemical and solvothermal routes and evaluated as an electrocatalyst for alcohol oxidation reactions (AORs). Despite having identical crystal and electronic structures, the mechanochemically synthesized Ni‐MOF (termed as MC‐MOF) exhibited ...
