Spatio-temporal dynamics and drivers of drying conditions in the HRB: Unraveling the role of precipitation intensity and total precipitation in drying risk

open access: yesJournal of Hydrology: Regional Studies
Study region: The Hangbu River Basin (HRB), located in eastern China, is the largest sub-basin of the Chaohu Lake Basin. Study focus: In recent decades, the HRB has experienced increased drying and spatial heterogeneity in its hydrological conditions ...

The design of a Space-borne multispectral canopy LiDAR to estimate global carbon stock and gross primary productivity [PDF]

open access: yes, 2011
Understanding the dynamics of the global carbon cycle is one of the most challenging issues for the scientific community. The ability to measure the magnitude of terrestrial carbon sinks as well as monitoring the short and long term changes is vital for ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library

open access: yesFEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Discussion on the formulas used to calculate the dissolution rate by the rock tablet method

open access: yesCarsologica Sinica
The dissolution rate of carbonate rocks is an important parameter for investigating the karst carbon cycle and evaluating the carbon sink effect; as well as a key indicator for studying karst development and karst hydrogeological problems.

Remote sensing of young leaf photosynthetic capacity in tropical and subtropical evergreen broadleaved forests [PDF]

open access: yesEarth System Science Data
Determining the large-scale RuBisCO carboxylation maximum rate (Vc,max25) in relation to leaf age is essential for evaluating the photosynthetic capacity of canopy leaves in global forests.

Carbon Cycle Uncertainty in REgional Carbon Cycle Assessment and Processes (RECCAP) [PDF]

open access: yesBiogeosciences, 2012
Characterisation of estimates of regional carbon budgets and processes is inherently a statistical task. In full form this means that almost all quantities used or produced are realizations or instances of probability distributions.

Ecosystem-driven karst carbon cycle and carbon sink effects

open access: yesJournal of Groundwater Science and Engineering, 2022
It is recognized that karst processes are actively involved in the current global carbon cycle based on twenty years research, and the carbon sink occurred in karst processes is possibly an important part of “missing sink” in global carbon cycle. In this

Carbon-ammonia pairs for adsorption refrigeration applications : ice making, air conditioning and heat pumping [PDF]

open access: yes, 2009
A thermodynamic cycle model is used to select an optimum adsorbent-refrigerant pair in respect of a chosen figure of merit that could be the cooling production (MJ m(-3)), the heating production (MJ m(-3)) or the coefficient of performance (COP).

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Classifying Inundation in a Tropical Wetlands Complex with GNSS-R

open access: yesRemote Sensing, 2019
The use of global navigation satellite system reflectometry (GNSS-R) measurements for classification of inundated wetlands is presented. With the launch of NASA’s Cyclone Global Navigation Satellite System (CYGNSS) mission, space-borne GNSS-R ...
