Abstract:

As part of a research program to develop gravity interpretation tools that can be merged with seismic techniques, a full 3-D complex structural inversion scheme for (possibly multibody) polyhedral models has been developed. The forward modeling algorithm was adopted from previous work. Because the inverse problem is generally very ill posed, several methods of regularizing the inversion were investigated and a combination of the most useful was adopted. The combination includes (i) a structured matrix formulation for the system equations, (ii) an analytical expression for the Jacobian calculat

Abstract:

Abstract Let D be a simple normal crossing divisor in a smooth complex projective variety X. We show that the existence on X-D of a non-trivial polarized complex variation of Hodge structures with integral monodromy implies that the pair (X,D) has a non-zero logarithmic symmetric differential (a section of a symmetric power of the logarithmic cotangent bundle). When the corresponding period map is generically immersive, we show more precisely that the logarithmic cotangent bundle is big.

Abstract:

Since the discovery of donor–acceptor (D–A) type molecules in the field of materials science, they have found great applicability in the field of photocatalysis. Most of these compounds are based on complex D–A–D structures or multi-D–A systems, such as 4CzIPN. Whereas these systems have been widely studied and applied as photocatalysts, simpler D–A structures remain less explored. Nevertheless, the simplicity of D–A structures makes them the ideal structures to further understand the structure–property relationship of D–A molecules for optimizing their photocatalytic performance by simpler mo

A small‐scale, shallow‐penetration 3-D reflection seismic survey has been carried out over stratified glacial formations to test the method’s potential for delineating fine structural details with a reasonable field effort and cost. Recording was carried out with a 96-channel engineering seismograph. Blank shotgun shells were used as the energy source. Field records were obtained with usable reflection energy up to 500 Hz, exploring approximately a 220-m cubical volume. Although special processing was required to attenuate strongly dispersed and scattered surface waves, a stacked data volume o

In this study, a computational seismic design routine is proposed based on a generalized response spectrum analysis for highly indeterminate structures with energy-dissipation members, such as viscous or elasto-plastic dampers. Complex stiffness terms are introduced to account for displacement-dependent damping, and a three-dimensional (3-D) element stiffness matrix with complex axial stiffness is proposed for elasto-plastic dampers. A modified complete quadratic combination method previously developed for real symmetric damped systems is extended to complex asymmetric damped systems, based on

This paper describes a research strategy in which complex data sets are represented as physical objects in a virtual 3-D environment. The advantage of such a representation is that it allows the observer to actively explore the virtual environment so that potential ambiguities found in typical 3-D projections could be resolved by the transformation resulting from the change in viewing perspective. The study reported here constitutes an initial condition in which subjects compared relative size of virtual cubes from two different viewpoints.

Reconstruction method of real objects into point cloud based on RGB images and Depth images (RGB-D Images) has been adopted in various fields. By utilizing such reconstruction method, it would be possible to efficiently measure the complex shape of objects, such as tetrapods, without directly contacting to them in the real experiment. However, the measurements of three-dimensional (3D) objects have rarely been used in hydrodynamic experiments. In the present study, the methodology was built to carry out hydraulic experiments and numerical simulations focusing on the displacement of complex obj

Ray‐based prestack depth migration fails to image quantitatively complex structures when a single arrival—for example, the first or the strongest one—is taken into account. In this paper, we investigate whether accounting for multiple arrivals in ray‐based preserved amplitude prestack depth migration allows one to improve quantitative imaging of complex media. The asymptotic ray‐Born migration/inversion, originally designed to process one single arrival, is extended to the case of multiple arrivals by accounting for the cross‐contributions of all the source and receiver raypaths.

Let Z be a compact complex (2n+1)-manifold which carries a complex contact structure, meaning a codimension-1 holomorphic sub-bundle D⊂TZ which is maximally non-integrable. If Z admits a Kähler-Einstein metric of positive scalar curvature, we show that it is the Salamon twistor space of a quaternion-Kähler manifold (M4n, g). If Z also admits a second complex contact structure [Formula: see text], then Z=CP2n+1. As an application, we give several new characterizations of the Riemannian manifold HPn= Sp(n+1)/(Sp(n)×Sp(1)).

Abstract:

The problem of high-performance systems for the big data transmission and processing fabrication determines the importance of creating hybrid photonic integrated circuits with complex architecture. We studied of three-dimensional photonic waveguide structures created by direct (3 + 1)D laser writing, with the aim of adding such structures to photonic integrated circuits.

Abstract:

The crystal structure of the nonstoichiometric complex of gramicidin D with NaI has been studied using synchrotron radiation at 100 K. The limiting resolution was 1.25 Å and theRfactor was 16% for 19 883 observed reflections. The general architecture of the antiparallel two-stranded gramicidin dimers in the studied crystal was a right-handed antiparallel double-stranded form that closely resembles the structures of other right-handed species published to date. However, there were several surprising observations. In addition to the significantly different composition of linear gramicidins ident

Abstract:

Cellular DNA is packaged into chromosomes through complex processes whereby the DNA becomes compacted up to 10,000-fold by assembly into higher-order structures. In spite of many decades of intense study, the details of this process are not known. In addition, there is little information describing the dynamics of these higher-order structures during DNA replication, transcription, and mitosis. The goal of our laboratory is to use state-of-the-art 3-D imaging methods to understand how DNA is arranged into chromosomes and how chromosomes are spatially and temporally organized in the nucleus.

Abstract:

The article deals with polysemantic words that are often found in complex metaphorical structures, which can be seen in speeches of modern politicians (B. Obama, D. Trump, D. Cameron, Queen Elizabeth II, etc.). The usage of metaphorical polysemy in political discourse and its reasons are considered and explained. The main goal of the article consists in the examination of the polysemantic structures phenomenon, the diversity of their meanings and their usage in modern English as parts of the metaphoric phrases.

Abstract:

SUMMARY Receiver function is important for imaging crustal and upper-mantle discontinuities. However, sparsely scattered stations could introduce imaging artefacts or misinterpretations for complex structures. We regularize a 3-D teleseismic wavefield to reduce these artefacts using radial basis function interpolation. First, we evaluated the feasibility of wavefield regularization with several typical models using synthetic data. The results demonstrate the high reliability of our method for recovering local 2-D and 3-D structures, even when seismic stations intentionally miss 95 per cent of

Abstract:

Abstract By regarding the complex indicatrix as an embedded CR-hypersurface of the holomorphic tangent bundle in a fixed point, we analyze some aspects of the relations between its CR structure and the considered contact structure. Moreover, using the classification of the almost contact metric structures associated with a strongly pseudo-convex CR-structure, of D. Chinea and C. Gonzales, we determine the classes corresponding to the natural contact structure of the complex indicatrix and the new structures obtained under a gauge transformation.

Abstract:

Micro electromechanical systems (MEMS) are finding uses in an increasing number of diverse applications. Currently the fabrication techniques used to produce such MEMS devices are primarily based on 2-D processing of thin films. The challenges faced by producing more complex structures (e.g. high aspect ratio, spans, and multi-material structures) require the development of new processing techniques. Potential solutions to these challenges based on low temperature processing of functional ceramics, selective chemical patterning, and micro-moulding are presented to show that it is possible to c
