Tree growth response to drought partially explains regional-scale growth and mortality patterns in Iberian forests
(Ecological Applications, 2022-07-01)Tree-ring data has been widely used to inform about tree growth responses to drought at the individual scale, but less is known about how tree growth sensitivity to drought scales up driving changes in forest dynamics. ... -
Tree influence exacerbates the El Niño effects over soil CO<inf>2</inf> emissions and its microclimatic controls
(Applied Soil Ecology, 2020-03-01)Dryland ecosystems are considered the largest global carbon sink. However, extreme climate phenomena like the El Niño events (EN) may change soil respiration (Rs) the CO2 emitted from soils resulting from biological ... -
Triku: a feature selection method based on nearest neighbors for single-cell data
(Oxford University Press, 2022-03-12)Abstract BACKGROUND: Feature selection is a relevant step in the analysis of single-cell RNA sequencing datasets. Most of the current feature selection methods are based on general univariate descriptors of the data ... -
Tunable Photodetectors via In Situ Thermal Conversion of TiS3 to TiO2
(MDPI, 2020-04-09)In two-dimensional materials research, oxidation is usually considered as a common source for the degradation of electronic and optoelectronic devices or even device failure. However, in some cases a controlled oxidation ... -
Tunable Superparamagnetic Ring (tSPRing) for Droplet Manipulation
(Wiley-VCH, 2021-05-13)The manipulation of droplets by magnetic field forms the basis of a fascinating technology that is currently in development. Often, the movement of droplets with magnets involves adding magnetic particles in or around the ... -
Tuning Electronic and Ionic Conductivities in Composite Materials for Electrochemical Devices
(ACS, 2021-03-11)Mixed conductors having both high ionic and electronic conductivity are needed in membrane electrode assemblies (MEA) present in electrochemical devices from fuel cells, to supercapacitors and all battery chemistries. ... -
Tuning the Properties of a UV-Polymerized, Cross-Linked Solid Polymer Electrolyte for Lithium Batteries
(MDPI, 2020-03-05)Lithium metal anodes have been pursued for decades as a way to significantly increase the energy density of lithium-ion batteries. However, safety risks caused by flammable liquid electrolytes and short circuits due to ... -
Tuning the Properties of Active Microtubule Networks by Depletion Forces
(American Chemical Society, 2021-07-06)Suspensions of microtubules and nonadsorbing particles form thick and long bundles due to depletion forces. Such interactions act at the nanometer scale and define the structural and dynamical properties of the resulting ... -
Twisted Aromatic Frameworks: Readily Exfoliable and Solution-Processable Two-Dimensional Conjugated Microporous Polymers
(Wiley VCH, 2017)Twisted two-dimensional aromatic frameworks have been prepared by overcrowding the nodes with bulky and rigid substituents. The highly distorted aromatic framework with alternating out-of-plane substituents results in ... -
Two-magnon bound state causes ultrafast thermally induced magnetisation switching
(Nature Publishing Group, 2013-11)There has been much interest recently in the discovery of thermally induced magnetisation switching using femtosecond laser excitation, where a ferrimagnetic system can be switched deterministically without an applied ... -
Two-Stage Multi-Objective Meta-Heuristics for Environmental and Cost-Optimal Energy Refurbishment at District Level
(MDPI, 2019-03-01)Energy efficiency and environmental performance optimization at the district level are following an upward trend mostly triggered by minimizing the Global Warming Potential (GWP) to 20% by 2020 and 40% by 2030 settled by ... -
