Abstract Ongoing global changes are expected to affect the worldwide production of many fisheries and aquaculture systems. Because invertebrates represent a relevant industry, it is crucial anticipate challenges that resulting from current environmental alterations. In this review, we rely on estimated physiological limits six commercialised species sea urchins ( Loxechinus albus , Mesocentrotu...

We give several examples and examine case studies of linear stochastic functional di erential equations. The examples fall into two broad classes: regular and singular, according to whether an underlying stochastic semi ow exists or not. In the singular case, we obtain upper and lower bounds on the maximal exponential growth rate 1 ( ) of the trajectories expressed in terms of the noise varianc...

Risk-averse optimization has attracted much attention in nite-dimensional stochastic programming. In this paper, we propose a risk-averse approach in the in nite dimensional context of shape optimization. We consider elastic materials under stochastic loading. As measures of risk awareness we investigate the expected excess and the excess probability. The developed numerical algorithm is based ...

Conventional work ow functionality like task sequencing, split parallelism, join synchronisation and iteration have proven e ective for business process automation and have widespread support in current work ow products. One the other hand, newer requirements for work ows are encountered in practice, opening grave uncertainties about the extensions for current languages. Di erent concepts, alth...

| Lagrangian stochastic models and algorithms are constructed and justi ed for solving the footprint problem, namely, the problem of calculation of the mean concentration and the ux of particles at a xed point released from a source arbitrarily situated in the space. The direct and adjoint Monte Carlo algorithms are suggested, and rigorous justi cations are given. Two di erent backward trajecto...

From the point of view of quality management, it is an important issue to reduce the transmission time in the network. The quickest path problem is to 6nd the path in the network to send a given amount of data from the source to the sink such that the transmission time is minimized. Traditionally, this problem assumed that the capacity of each arc in the network is deterministic. However, the c...

The mol-ecule of the title compound C7H8N4O·0.5H2O, alternatively called (E)-1-(pyridin-4-yl-methyl-ene)semi-carb-azide hemihydrate, is in the E conformation and is almost planar; the r.m.s. deviation of the positions of the atoms of the pyridine ring from the best-fit plane is 0.0039 Å. The C, N and O atoms of the rest of the mol-ecule sits close on this plane with a largest deviation of 0.115...

In the title compound, C(4)H(6)N(3) (+)·H(2)O(4)P(-)·H(2)O, the pyrimidin-ium ring is essentially planar, with an r.m.s. deviation of 0.0016 Å. In the structure, pairs of symmetry-related anions are connected into centrosymmetric clusters via strong O-H⋯O hydrogen bonds forming six-membered rings with an R(2) (2)(6) motif. These clusters are inter-connected via water mol-ecules through OW-H⋯O h...

Abstract Combining spatially localized X-ray diffraction (XRD) with microtomography (XMT) enables the mapping of micro- and nanoscale structures simultaneously. The combination these methods results in a powerful tool when considering structural studies hierarchical materials, allowing one to couple relationships connections at various scales. In this study, XMT was used map anatomy cellular 3D...

We study buoyancy driven convection in a laterally heated and two dimensional cavity under a uctuating acceleration eld, to model ow conditions in a microgravity environment. In the limit of a large aspect ratio cavity, (the length in the direction perpendicular to the temperature gradient is much larger than in the parallel direction), an analytic solution can be found in which the ow reaches ...
