Low temperature stimulates spatial molecular reprogramming of the Arabidopsis seed germination programme [PDF]

open access: yes, 2021
The timing of the germination of seeds is highly responsive to inputs from the environment. Temperature plays a key role in the control of germination, with low temperatures acting to stimulate this developmental transition in many species.

Low temperature ellipsometry of NaV2O5 [PDF]

open access: yes, 1999
The dielectric function of alpha'NaV2O5 was measured with electric field along the a and b axes in the photon energy range 0.8-4.5 eV for temperatures down to 4K.

Low-temperature saw damage gettering to improve minority carrier lifetime in multicrystalline silicon [PDF]

open access: yes, 2017
The minority carrier lifetime in multicrystalline silicon − a material used in the majority of today's manufactured solar cells − is limited by defects within the material, including metallic impurities which are relatively mobile at low temperatures ...

Low-Temperature Physics [PDF]

open access: yesNature, 1948
THE great attraction of low temperature physics as a field of research is that so many of the phenomena still lack any fundamental theory, so that the outcome of any new experiment is rarely a foregone conclusion. The outstanding phenomena at present requiring something deeper than ‘phenomen-ologica theories are superconductivity and the properties of ...

Low-molecular-weight hydroxyacids in marine atmospheric aerosol: evidence of a marine microbial origin [PDF]

open access: yesBiogeosciences, 2014
Lactic acid (LA) and glycolic acid (GA), which are low-molecular-weight hydroxyacids, were identified in the particle and gas phases within the marine atmospheric boundary layer over the western subarctic North Pacific. A major portion of LA (81%) and GA

Low Temperature Fatigue Crack Growth Test and Life Estimation of 7475-T7351 Al-ally by ANN [PDF]

open access: yes, 2016
In the present wok fatigue crack growth tests have been performed under interspersed mode-I overload on 7475-T7351 Al-alloy. The overloads with an overload ratio of 2 were given at 0C, ndash;30C, ndash;45C, ndash;60C, and ndash;75C at a loading rate of 7

Thermal Effects in Low-Temperature QED [PDF]

open access: yes, 2001
QED is studied at low temperature ($T\ll m$, where $m$ is the electron mass) and zero chemical potential. By integrating out the electron field and the nonzero bosonic Matsubara modes, we construct an effective three-dimensional field theory that is ...

Low temperature opacities [PDF]

open access: yesInternational Astronomical Union Colloquium, 1994
AbstractThe importance of low temperature opacities in stellar calibrations led us to compute new sets of Rosseland mean opacities for different Z-values. For the solar metallicity, these tables have been compared to those of Alexander (1975), Cox (1983), Sharp (1991) and Kurucz (1992).

Light Higgs channel of the resonant decay of magnon condensate in superfluid 3He-B

open access: yesNature Communications, 2016
The order parameter describing the spontaneous symmetry breaking which occurs when a system becomes a superfluid is analogous to the Higgs field in particle physics from which the Higgs boson arises. Here, the authors demonstrate the existence of a light
