Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2018 Spatial variations in yield occur in all agricultural fields to some degree. Knowledge of the reasons for these variations, especially temporally stable yield patterns, is needed in order to improve productivity by changing production methods or inputs ...

FEBS Letters, EarlyView.Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Delayed compression and breakage of crushed mudstones due to the drying/wetting and temperature cycles [PDF]
E3S Web of ConferencesSoft sedimentary rocks, especially mudstones, disintegrated or crumbled when subjected to cyclic drying and wetting, known as slaking, which was the cause of severe slope failures and ground settlement.

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Numerical simulation of cone penetration test in a small-volume calibration chamber
, 2022 S.309-315In this study, laboratory Cone Penetration Tests (CPTs) were conducted in the MARUM Calibration Chamber (MARCC) with three lateral boundary conditions: (BC), constant stress, constant strain and the simulated field conditions with constant ...

IMPACT OF THE REPEATED TRACTOR PASSES ON SOME PHYSICAL PROPERTIES OF SILTY LOAM SOIL [PDF]
Poljoprivreda, 2011 The aim of this paper was to quantify soil compaction induced by tractor traffic on untilled wet silty loam soil (Mollic Fluvisol). Changes in penetration resistance, bulk density and total porosity were measured for detecting the soil compaction ...

Subtype‐specific enhancer RNAs define transcriptional regulators and prognosis in breast cancers
Molecular Oncology, EarlyView.This study employed machine learning methodologies to perform the subtype‐specific classification of RNA‐seq data sets, which are mapped on enhancers from TCGA‐derived breast cancer patients. Their integration with gene expression (referred to as ProxCReAM eRNAs) and chromatin accessibility profiles has the potential to identify lineage‐specific and ...
