Geometry of Vegetation Pattern
One of the effects of climate change is the phenomenon of desertification, a process that occurs in semi-arid and arid areas and causes land degradation as well as vegetation loss. Due to the lack of resources, vegetation self-organizes to sustain itself by forming large-scale spatial patterns.

Refined tautological relations on moduli spaces of curves
The key purpose of this project is to study tautological relations on the level of closed differential forms or even integral cochains (i.e. we don't take classes in cohomology).

Regulation of actomyosin contraction as a driving force of invasive lobular breast cancer
In this thesis, we used genetically engineered mouse models and a variety of cell-culture based assays to identify genes and pathways that are involved in the development and treatment of invasive lobular carcinoma (ILC).

Towards a single-molecule FRET study of Frauenfelder's nonexponential rebinding of CO in myoglobin
Early time-resolved experiments by Frauenfelder on the ensemble of the kinetic rebinding of CO to myoglobin molecules resulted in a stretched exponential relaxa-tion due to a very large spread of the reaction rates of individual molecules.

Differentiële effecten van digitale ondersteuning van rekenvaardigheden bij kleuters met milde perinatale problemen
Kinderen die laat-prematuur oftewel iets te vroeg geboren zijn - tussen de 34 en 38 weken- of klein zijn voor de duur van de zwangerschap, worden gezien als relatief kwetsbaar. Door deze milde perinatale problemen hebben zij niet alleen een grotere kans op medische problemen, maar ook op cognitieve…

Digitale prentenboeken stimuleren de taalvaardigheid van kleuters
Het promotieonderzoek van orthopedagoog Rachel Plak toont aan dat een deel van de kleuters pas leert als de boeken filmachtige beelden en muziek bevatten. Voor deze kleuters is de implementatie van digitale prentenboeken in het curriculum van het kleuteronderwijs cruciaal.

Orkanen woeden ook diep in het inwendige van reuzenplaneet Jupiter
De winden op de planeet Jupiter dringen diep tot wel 3000 kilometer diep door in het binnenste van de gasreus. Dat ontdekten de Leidse astronoom Yamila Miguel en collega-astronomen in data van de NASA-sonde Juno. Ze publiceren erover in drie artikelen in Nature op 8 maart.

Management of Small-Scale Fisheries at the Elephant Marsh in Malawi
Wetlands provide many ecosystem goods and services which include fish production. The sustainability of small-scale fisheries (SSF) has received considerable attention in recent years because fish is one of the major sources of animal protein to a considerable fraction of the global population which…
