Optimistic NAUTILUS navigator for multiobjective optimization with costly function evaluations
2022
AbstractWe introduce novel concepts to solve multiobjective optimization problems involving (computationally) expensive function evaluations and propose a new interactive method called O-NAUTILUS. It combines ideas of trade-off free search and navigation (where a decision maker sees changes in objective function values in real time) and extends the NAUTILUS Navigator method to surrogate-assisted optimization. Importantly, it utilizes uncertainty quantification from surrogate models like Kriging or properties like Lipschitz continuity to approximate a so-called optimistic Pareto optimal set. This enables the decision maker to search in unexplored parts of the Pareto optimal set and requires …
Analysis of variability in divergence and turn-over induced by three idealized convective systems with a 3D cloud resolving model
2020
Abstract. The sensitivity of upper tropospheric and lower stratospheric convective outflows and related divergence fields is analysed using an ensemble of cloud resolving model (CM1) simulations in LES-mode including various physically manipulated simulations for three different convective systems initialized with an idealized trigger. The main goal of this study is to assess to what extend the divergence field depends on cloud microphysical processes, the mode of convection and on the processes of convective momentum transport and moist static energy redistribution. We find that latent heat release (representing the microphysical uncertainty) plays an essential role by explaining much of m…
Influence of the Madden-Julian Oscillation on East African rainfall. Part I: Intraseasonal variability and regional dependency
2006
The influence of the Madden–Julian Oscillation (MJO) on rainfall amounts over Equatorial East Africa (Kenya and northern Tanzania) is analysed for the period 1979–95 at the intraseasonal (pentad) time-scale. The two rainy seasons (March to May and October to December) are considered. Intraseasonal wet events in East Africa are embedded in large-scale zonal circulation anomaly patterns along the equator, showing distinct eastward propagation. It is further found that these ‘wet’ events display a clear phasing with respect to the MJO cycle. This phasing is expressed as out-of-phase variations between the Highland and the coastal areas. Such a pattern is suggested to reflect different rain-cau…
Novel lithocholaphanes: Syntheses, NMR, MS, and molecular modeling studies
2007
Abstract Novel head-to-head lithocholaphanes 6 and 11 have been synthesized via precursors 1 – 5 and 7 – 10 with overall good yields, and characterized by 1 H, 13 C, and 15 N NMR spectroscopy, ESI-TOF mass spectrometry, thermal analysis, and molecular modeling. In addition, the binding abilities of 6 and 11 towards alkali metal cations have been investigated via competitive complexation studies using equimolar mixtures of Li + , Na + , K + , and Rb + -cations, and cholaphanes 6 and 11 . The formation of cation–cholaphane adducts was detected by ESI-TOF mass spectrometry. The trends in these comparative binding studies are nicely reproduced theoretically with PM3 energetically optimized stru…

ChemInform Abstract: Comparative G2(MP2) Molecular Orbital Study of B3H7XH3 and H3BXH3 Donor-Acceptor Complexes (X: N, P, and As).
2010
B3H7XH3 and H3BXH3 (X = N, P, and As) have been studied as donor−acceptor complex type at the G2(MP2) level of theory. Both single- and double-bridged structures of B3H7 Lewis acid are taken into account. Although the double-bridged structure is energetically favored in the isolated state, the coordination prefers the single-bridged one. The monoborane adducts adopt the staggered arrangement with C3v symmetry. The energetic analysis by natural bond orbital theory shows that the decrease of hyperconjugative contribution upon complexation in the B3H7 moiety has, as consequence, a loss of symmetry for B3H7XH3 (X= P and As) complexes. In the two series, the coordination is the result of two opp…
Structure and Dilution of Mesogenic Side Chains in Liquid Crystalline Polysiloxanes
1988
Abstract The structure of the smectic phases in four series of homo- and copolymers based on dimethylsiloxane chains with a definite variation of the concentration of the paired mesogenic side chains has been investigated by means of X-ray methods. The dilution of the mesogenic moiety was achieved by insertion of additional dimethylsiloxane segments. A nearly linear dependence of the layer spacings on the dilution has been found. A model of the structure is proposed which consists of two sublayers one of which contains the irregularly arranged main chain whereas the other one is formed by the side chains.

Heritage and Cultural Policy in France under the Fifth Republic
2003
International audience; In the French historical tradition, four approaches at least have been heavily exploited. One seminal study defines the concept longitudinally in terms of religion, the monarchy, the family, the nation, the administration and science. Another essay uses allegory in an attempt to penetrate the proclaimed, avowed or unspoken motives underlying the notion of heritage. Another work uses the criterion of restoration to determine when a historical monument falls into the category of heritage. Fourth, a recent ground-breaking treatise considers heritage in historical and archaeological practice as reflecting representations of citizenship and the nation. Our angle of attack…
Between improvisation and inevitability: former Latvian officials’ memoirs of the Soviet era
2016
ABSTRACTThis article deals with the autobiographies of former Soviet officials that have been published in Latvia since the 1990s. In particular, it focuses on three interrelated layers of biographical narrative: construction of social identity, strategies for avoiding the stigmatization of collaboration, and comparisons between the Soviet and post-Soviet experience. The article contends that former officials in their memoirs use a pragmatic representation of the Soviet past as the major locus of their positive identity. Through this genuine representation of the past, autobiographers emphasize virtues that might be accepted by a post-Soviet neoliberal society.
