recommendations! Published in 2020 at "Annals of Forest Science"

DOI: 10.1007/s13595-020-00956-y

Abstract: Intra-annual wood density fluctuations are valuable indicators of the role of the local climate and provenance origins on tree growth. These intra-ring wood features were the most informative about local adaptation and phenotypic plasticity ofPinus… read more here.

DOI: 10.1016/j.fusengdes.2018.03.035

Abstract: Abstract The magnetohydrodynamic (MHD) modes and sawtooth activities are observed in many discharges in 100 GHz interferometer signal in Aditya tokamak. Two types of discharges are observed: one with a single dominant mode and the other… read more here.

DOI: 10.1016/j.oceaneng.2020.107277

Abstract: abstract One of the main causes of the formation of internal waves is the ocean currents, from the seabed's mounds. For this reason, numerous empirical studies have been carried out in laboratories on the flow… read more here.

DOI: 10.1021/acs.jctc.4c01047

Abstract: The standard definition of particle number fluctuations based on point-like particles neglects the excluded volume effect. This leads to a large and systematic finite-size scaling and an unphysical surface term in the isothermal compressibility. We… read more here.

DOI: 10.1029/2018gl077788

Abstract: Abstract Bursts of X‐rays and γ‐rays are observed from lightning and laboratory sparks. They are bremsstrahlung from energetic electrons interacting with neutral air molecules, but it is still unclear how the electrons achieve the required… read more here.

DOI: 10.1029/2020gl089628

Abstract: Some physical processes due to Sun‐Earth interaction can influence the configuration and the dynamics of the high‐latitude ionospheric plasma, particularly during geomagnetically disturbed periods. A possible consequence of this interaction is the occurrence of turbulent… read more here.

DOI: 10.1039/d1sm01183a

Abstract: Giant number fluctuations are often considered as a hallmark of the emergent nonequilibrium dynamics of active fluids. However, these anomalous density fluctuations have only been reported experimentally in two-dimensional dry active systems heretofore. Here, we… read more here.

DOI: 10.1073/pnas.2421518122

Abstract: Significance The nonmotility activities, e.g., cell pulsation, are generic features of cell tissues. However, how this activities affect the structure, dynamic, and density fluctuations of cell tissues remains poorly understood. In this work, based on… read more here.

DOI: 10.1088/1741-4326/ab15b1

Abstract: Previous investigations of small-scale density fluctuation by means of correlation reflectometry in T-10 tokamak revealed the existence of several density fluctuation types and strong radial and poloidal variation of their amplitudes and correlation properties. This… read more here.
