A Flexible Network Approach to Privacy of Blockchain Transactions
For preserving privacy, blockchains can be equipped with dedicated mechanisms
to anonymize participants. However, these mechanism often take only the
abstraction layer of blockchains into account whereas observations of the
underlying network traffic can reveal the originator of a transaction request.
Previous solutions either provide topological privacy that can be broken by
attackers controlling a large number of nodes, or offer strong and
cryptographic privacy but are inefficient up to practical unusability. Further,
there is no flexible way to trade privacy against efficiency to adjust to
practical needs. We propose a novel approach that combines existing mechanisms
to have quantifiable and adjustable cryptographic privacy which is further
improved by augmented statistical measures that prevent frequent attacks with
lower resources. This approach achieves flexibility for privacy and efficency
requirements of different blockchain use cases.Comment: 6 pages, 2018 IEEE 38th International Conference on Distributed

Influence of water supply on farm productivity in the north-eastern wheatbelt
In the area with reliable reticulated water supplies, average what yield, average wool production and average number of sheep per pastured hectare showed a positive correlation with annual rainfall in all but one year. By contrast, in the area served by on-farm water supplies only, average wheat yield and annual rainfall were strongly correlated, whereas average wool production and average number of sheep per pastured hectare showed a weaker correlation with annual rainfall. These correlations suggest tt on farms with a reliable water supply, livestock numbers have been adjusted annually to ensure optimum utilisation of available feed in all seasons

Mercury's Internal Structure
We describe the current state of knowledge about Mercury's interior
structure. We review the available observational constraints, including mass,
size, density, gravity field, spin state, composition, and tidal response.
These data enable the construction of models that represent the distribution of
mass inside Mercury. In particular, we infer radial profiles of the pressure,
density, and gravity in the core, mantle, and crust. We also examine Mercury's
rotational dynamics and the influence of an inner core on the spin state and
the determination of the moment of inertia. Finally, we discuss the
wide-ranging implications of Mercury's internal structure on its thermal
evolution, surface geology, capture in a unique spin-orbit resonance, and
magnetic field generation.Comment: 36 pages, 11 figures, in press, to appear in "Mercury - The View
