Armfuls of Eclectic Pieces: Poetic-Photographic Essay [PDF]

open access: yeseTropic: electronic journal of studies in the tropics, 2020
As a writer and poet, I am particularly interested in language(s), in words in Tahitian and in French. Since 2016, I have explored themes of survival, duration, continuity, and transmission through poetry and artworks made of materials evoking cracks ...

Agricultural Landscape Heterogeneity Matter: Responses of Neutral Genetic Diversity and Adaptive Traits in a Neotropical Savanna Tree

open access: yesFrontiers in Genetics, 2021
Plants are one of the most vulnerable groups to fragmentation and habitat loss, that may affect community richness, abundance, functional traits, and genetic diversity.

The minimum mass for star formation, and the origin of binary brown dwarfs [PDF]

open access: yes, 2006
Our first aim is to calculate the minimum mass for Primary Fragmentation in a variety of potential star-formation scenarios, i.e. (i) hierarchical fragmentation of a 3-D medium; (ii) one-shot, 2-D fragmentation of a shock-compressed layer; (iii ...

Identification of programmed cell death in situ via specific labeling of nuclear DNA fragmentation

open access: yesJournal of Cell Biology, 1992
Programmed cell death (PCD) plays a key role in developmental biology and in maintenance of the steady state in continuously renewing tissues. Currently, its existence is inferred mainly from gel electrophoresis of a pooled DNA extract as PCD was shown ...

Ergodicity Breaking Arising from Hilbert Space Fragmentation in Dipole-Conserving Hamiltonians [PDF]

open access: yesPhysical Review X, 2019
We show that the combination of charge and dipole conservation---characteristic of fracton systems---leads to an extensive fragmentation of the Hilbert space, which in turn can lead to a breakdown of thermalization.

Systematic classification of unknown metabolites using high-resolution fragmentation mass spectra

open access: yesNature Biotechnology, 2020
Metabolomics using nontargeted tandem mass spectrometry can detect thousands of molecules in a biological sample. However, structural molecule annotation is limited to structures present in libraries or databases, restricting analysis and interpretation ...

ETHNIC MINORITY ELITES IN POST-COMMUNIST COUNTIRES: THE CASE OF ESTONIA

open access: yesСравнительная политика, 2015
The aim of the article is to study the unity versus fragmentation patterns of minority elites and its influence on democratic processes. More generally, the article makes an attempt to analyse the reasons why the “voice“ of the noncore elite is not heard

Weak solutions to the continuous coagulation equation with multiple fragmentation [PDF]

open access: yes, 2011
The existence of weak solutions to the continuous coagulation equation with multiple fragmentation is shown for a class of unbounded coagulation and fragmentation kernels, the fragmentation kernel having possibly a singularity at the origin.

Habitat fragmentation and its lasting impact on Earth’s ecosystems

open access: yesScience Advances, 2015
Urgent need for conservation and restoration measures to improve landscape connectivity. We conducted an analysis of global forest cover to reveal that 70% of remaining forest is within 1 km of the forest’s edge, subject to the degrading effects of ...
