Further information on the life of Charles Moore (1815-1881), Somerset geologist.

Copp et al. (1999) published an account of the life and work of Charles Moore, the Victorian amateur geologist whose fine collection is now held mainly by the Bath Royal Literary and Scientific Institution and the Somerset County Museum, Taunton. This note aims to amend and extend some information in that paper

An account of Mary Anning (1799-1847), fossil collector of Lyme Regis, Dorset, England, published by Henry Rowland Brown (1837-1921) in the second edition (1859) of Beauties of Lyme Regis

The publication of the now rare second edition of the guidebook The Beauties of Lyme Regis... by Lyme native Henry Rowland Brown (1837-1921) is dated to 1859. The known link of Brown’s family to Anning’s increases the significance of his book as a source for her, particularly the second edition which has a more extensive account of her than the first; relevant extracts are reproduced. His book has become a major source for writers on Anning, but only in corrupted form because of incompetent piracy by a later writer in a general magazine

An anonymous account of Mary Anning (1799-1847), fossil collector of Lyme Regis, Dorset, England, published in All the year round in 1865, and its attribution to Henry Stuart Fagan (1827-1890), schoolmaster, parson and author

An article on the fossil collector Mary Anning (1799-1847), published in All the Year Round in 1865, and much used in Anning literature, is usually ascribed to Charles Dickens. In fact it was by the Reverend Henry Stuart Fagan (1827-1890), grammar school headmaster, Church of England parson, and literary man. It is neither original nor reliable, and introduced errors into the Anning literature which are still problematic. The methodology of attribution of anonymous articles is discussed

The tail of the Jurassic fish Leedsichthys problematicus (Osteichthyes: Actinopterygii) collected by Alfred Nicholson Leeds - an example of the importance of historical records in palaeontology

The specimen of the tail of <i>Leedsichthys problematicus</i>, now in The Natural History Museum, London, was one of the most spectacular fossil vertebrates from the Oxford Clay Formation of Peterborough, but as an isolated find it shares no bones in common with the holotype of the genus and species. However, a letter from Alfred Nicholson Leeds and related documents cast valuable new light on the excavation of the tail, indicating that it was discovered with cranial bones, gill-rakers, and two pectoral fins, thereby including elements that can potentially be compared with those of the holotype. The documents also clearly indicate that The Natural History Museum's specimen is not part of the same individual as any other numbered specimen of <i>Leedsichthys</i> as had been speculated on other occasions. The maximum size of the animal represented by The Natural History Museum's specimen was possibly around 9 metres, considerably less than previous estimates of up to 27.6 metres for <i>Leedsichthys</i>. Historical documentary evidence should therefore be rigorously checked both when studying historical specimens in science, and in preparing text for museum display labels

Asymptotic Analysis of Coagulation–Fragmentation Equations of Carbon Nanotube Clusters

The possibility of the existence of single-wall carbon nanotubes (SWNTs) in organic solvents in the form of clusters is discussed. A theory is developed based on abundletmodel for clusters describing the distribution function of clusters by size. The phenomena have a unified explanation in the framework of the bundlet model of a cluster, in accordance with which the free energy of an SWNT involved in a cluster is combined from two components: a volume one, proportional to the number of moleculesnin a cluster, and a surface one, proportional ton1/2. During the latter stage of the fusion process, the dynamics were governed mainly by the displacement of the volume of liquid around the fusion site between the fused clusters. The same order of magnitude for the average cluster-fusion velocity is deduced if the fusion process starts with several fusion sites. Based on a simple kinetic model and starting from the initial state of pure monomers, micellization of rod-like aggregates at high critical micelle concentration occurs in three separated stages. A convenient relation is obtained for <n> at transient stage. At equilibrium, another relation determines dimensionless binding energy α. A relation with surface dilatational viscosity is obtained

Condensation and interaction range in harmonic boson traps: a variational approach

For a gas of N bosons interacting through a two-body Morse potential a variational bound of the free energy of a confined system is obtained. The calculation method is based on the Feynman-Kac functional projected on the symmetric representation. Within the harmonic approximation a variational estimate of the effect of the interaction range on the existence of many-particle bound states, and on the N-T phase diagram is obtained.Comment: 14 pages+4 figures, submitted to phys.rev.

Single-cell reconstruction of follicular remodeling in the human adult ovary

The ovary is perhaps the most dynamic organ in the human body, only rivaled by the uterus. The molecular mechanisms that regulate follicular growth and regression, ensuring ovarian tissue homeostasis, remain elusive. We have performed single-cell RNA-sequencing using human adult ovaries to provide a map of the molecular signature of growing and regressing follicular populations. We have identified different types of granulosa and theca cells and detected local production of components of the complement system by (atretic) theca cells and stromal cells. We also have detected a mixture of adaptive and innate immune cells, as well as several types of endothelial and smooth muscle cells to aid the remodeling process. Our results highlight the relevance of mapping whole adult organs at the single-cell level and reflect ongoing efforts to map the human body. The association between complement system and follicular remodeling may provide key insights in reproductive biology and (in) fertility
