The effects of anthropogenic warming on the hydroclimate of California are becoming more pronounced with the increased frequency of multi-year droughts and flooding. As a past analog for the future, the Paleocene–Eocene Thermal Maximum (PETM) is a

The composite section from ODP Site 846 has provided key data sets for Pliocene stable isotope and paleoclimatic time series. We document here apparent outliers in previously published data sets for stable isotopes and alkenone-derived sea surface te

A genealogical model describing the dynamics of a binary branching system of astrocytes and microglia which takes into account a developmental hierarchy, is proposed. The model consists of a scheme of developmental pathways interconnecting the elemen

We report the scaling behavior of 1∕f noise in single-walled carbon nanotube devices. In this study we use two-dimensional carbon nanotube networks to explore the geometric scaling of 1∕f noise and find that for devices of a given resistance the

We report the use of carbon nanotubes as a sensor for chemical nerve agents. Thin-film transistors constructed from random networks of single-walled carbon nanotubes were used to detect dimethyl methylphosphonate (DMMP), a simulant for the nerve agen

We report on the transport properties of random networks of single-wall carbon nanotubes fabricated into thin-film transistors. At low nanotube densities (∼1 μm−2) the networks are electrically continuous and behave like a p-type semiconductor w

A steady state model of haemopoiesis was derived recently from correlations of lineages (Novak JP & Necas E (1994). Proliferation differentiation pathways of murine haemopoiesis correlation of lineage fluxes. Cell Proliferation, 27, 597). Since the d

A quantitative analysis of literature data on muiine bone marrow haemopoiesis was performed in order to determine how the haemolpoietic system fulfils requirements of cell turnover in the normal steady state. In particular, the production rates (flux

The characteristic form of the probability distributions of in vitro grown colonies is analysed and experimental results are shown to be well approximated by an exponential dependence. It is argued that this type of dependence is very frequent in nat
