Hotplate precipitation gauge calibrations and field measurements [PDF]
Atmospheric Measurement Techniques, 2018 First introduced in 2003, approximately 70 Yankee Environmental Systems (YES) hotplate precipitation gauges have been purchased by researchers and operational meteorologists. A version of the YES hotplate is described in Rasmussen et al.

Determining $H_0$ with Bayesian hyper-parameters [PDF]
JCAP03(2017)056, 2016 We re-analyse recent Cepheid data to estimate the Hubble parameter $H_0$ by using Bayesian hyper-parameters (HPs). We consider the two data sets from Riess et al 2011 and 2016 (labelled R11 and R16, with R11 containing less than half the data of R16) and include the available anchor distances (megamaser system NGC4258, detached eclipsing binary ...

Manifestations of the pseudogap in the BOSON-FERMION model for Bose-Einstein condensation driven Superconductivity [PDF]
Phys. Rev. B 53 (1996) R11 961, 1996 The normal state behaviour of the density of states of the electrons described by the BOSON - FERMION model for Bose-Einstein condensation driven superconductivity is characterized by the appearence of a pseudogap which developes into a true gap upon lowering the temperature and the superconducting critical temperature is approached.

Electronic Raman-scattering study of low-energy excitations in single and double CuO_2-layer Tl-Ba-(Ca)-Cu-O superconductors [PDF]
Phys. Rev. B 56, R11 427 (1997), 1997 Low energy Raman continuum and the redistribution of the continuum to a peak (2\Delta-peak) in the superconducting state have been studied in Tl-Ba-(Ca)-Cu-O superconductors with single (Tl-2201) and double (Tl-2212) CuO_2 layer. The 2\Delta/k_BT_c ratios in A_1g and B_1g symmetries are larger for Tl-2212 than for Tl-2201.

Fully Off-shell Effective Action and its Supersymmetry in Matrix Theory [PDF]
, 2001 As a step toward clarification of the power of supersymmetry (SUSY) in Matrix theory, a complete calculation, including all the spin effects, is performed of the effective action of a probe D-particle, moving along an arbitrary trajectory in interaction ...

Fires and Local Labor Markets [PDF]
arXiv, 2023 We study the dynamic effects of fires on county labor markets in the US using a novel geophysical measure of fire exposure based on satellite imagery. We find increased fire exposure causes lower employment growth in the short and medium run, with medium-run effects being linked to migration.

Study of spin-Peierls transition in alpha'--NaV2O5 by infrared reflectivity [PDF]
Phys. Rev. B 57, R11 035 (1998), 1998 Polarized infrared reflectivity measurements have been performed on single crystals of the spin-Peierls compound alpha'-NaV2O5 in the temperature range 20-300 K. Pronounced spectral features associated with the formation of the dimerized phase were detected both in the a- and b-polarizations (perpendicular and parallel to the spin-1/2 chains ...
