Composite Description

We review models of new physics in which dark matter arises as a composite bound state from a confining strongly-coupled non-Abelian gauge theory. We discuss several qualitatively distinct classes of composite candidates, including dark mesons, dark baryons, and dark glueballs. We highlight some of the promising strategies for direct detection, especially through dark moments, using the symmetries and properties of the composite description to identify the operators that dominate the interactions of dark matter with matter, as well as dark matter self-interactions. We briefly discuss the implications of these theories at colliders, especially the (potentially novel) phenomenology of dark mesons in various regimes of the models. Throughout the review, we highlight the use of lattice calculations in the study of these strongly-coupled theories, to obtain precise quantitative predictions and new insights into the dynamics.

Composite Description

In this study, a methodology integrating a sketch design recognition approach with an interactive genetic algorithm is proposed to help laypersons get clothes reflecting their preferences. The sketch design recognition approach consists of a composite description model, a sketch recognition method and a database. First, a composite description model based on the knowledge of fashion design is developed to describe the characteristics of a skirt. Second, a sketch recognition method is used to help laypersons get satisfactory clothes. Third, a database in constructed to record general elements of skirts. Moreover, an interactive genetic algorithm (IGA) is used to accelerate the sketch recognition process. The experimental results demonstrate that the proposed method can 'recognize' users' preferred styles efficiently. The subjective evaluation has shown that the system can help general consumers without any fashion design or sketch training to create their own designs.

Composite Description

AbstractBased on observations of naleds (also called aufeis or icings) grown in a refrigerated laboratory flume, a detailed, composite description of the processes associated with naled ice growth is presented. A spread length is derived that represents a mass balance between the water supplied to a naled’s surface and the ice that freezes on to the surface. Herein, this spread length is termed an equilibrium length. Guided by this concept of equilibrium length and the laboratory data, length- and time-scales applicable to the growth of two-dimensional naleds are proposed. These scales proved useful for normalizing the times and streamwise lengths that correspond to distinct phases of naled ice growth. It is observed that, even in a laboratory flume, naleds spread and thicken in a complex, layer-by-layer manner.To the best of the authors’ knowledge, this is the first reported laboratory study on naled ice growth. The descriptions and concepts presented herein should be useful to engineers concerned with the effects of naleds on engineering works, and of interest to those who are planning experiments on naleds.

Composite Description

The use of the superspace formalism is extended to the description and refinement of the homologous series of modular structures with two symmetry-related modules with different orientations. The lillianite homologous series has been taken as a study case. Starting from a commensurate modulated composite description with two basic subsystems corresponding to the two different modules, it is shown how a more efficient description can be achieved using so-called zigzag modulation functions. These linear zigzag modulations, newly implemented in the program JANA2006, have very large fixed amplitudes and introduce in the starting model the two orientations of the underlying module sublattices. We show that a composite approach with this type of function, which treats the cations and anions as two separate subsystems forming a misfit compound, is the most appropriate and robust method for the refinements.

Composite Description

Whidborne gave a composite description of certain specimens from the Upper Devonian of Pilton and other localities which he grouped together and ascribed to the Carboniferous species P. (Buxtonia) scabriculus Mart. (Whidborne, 1897, 170, pi. xx, figs. 16–18, pi. xxi, fig. 12), but he considered that it was difficult to distinguish some of them from those which he ascribed to Strophalosia productoides. We cannot agree with his reference of any of them to Martin's Carboniferous species. The best preserved and first example [H. 286] which he figured (1897, pi. xx, fig. 16) is a pedicle-valve from “Smoking House Lane”. It has a transversely subquadrate shape with subrectangular cardinal angles not produced; the body is strongly arched longitudinally but only moderately convex transversely, and it has a weak median longitudinal depression, but descends steeply on each side to the smalt ears; it is covered by regular continuous rounded costae of equal size, about fifty in number, some of which bifurcate at about one-third to two-thirds their length, and very few of them show any small swellings on their course as in P. scabriulus; a few faint narrow concentric rugae are traceable on the posterior third of the body producing weak coarse reticulation; the umbo is very broad, rounded and incurved, projecting over the hinge-line; the ears, which are much depressed but not sharply marked off from the body, are triangular in shape and are crossed by a few narrow concentric rugae which bifurcate somewhat irregularly before reaching the hinge-line; a few large coarse spinose tubercles or spine-bases lie near the junction of the body with the ears. This pedicle-valve is sufficiently preserved to indicate a distinct species, for which the name porteri is proposed.

Composite Description

AbstractThe purpose of this phenomenological study is to describe the experience of enduring marriage in mid-life. The literature reveals a lack of research about contemporary mid-life marriage, reflecting only theoretical pieces and research studies on marital happiness, factors that make a marriage successful, and variables contributing to divorce. Noticeably absent are studies conducted from a phenomenological philosophical perspective. Questioning what enduring marriage involves for individuals in mid-life served to orient the researchers to the meaning of the experience. Seventeen volunteers participated in twenty-six initial and follow-up interviews. Using van Manen's methodological structure of human science research, a composite description that reflects enduring marriage in mid-life emerged. Two essential themes that characterize the experience, The Threads that Bind Us and A Season of Change and seven sub-themes explicating these essential themes portray the partnership of enduring mid-life marriage. The themes that comprise the structure of the experience reflect its form as a relational, time-space, and corporeal phenomenon. The findings are described in detail using narrative description in order to offer a rich account of each theme, and the implications provide a direction for future research.

Composite Description

I seek the experience of the primary school children who participated in the SEL Activities instructing self-regulation skill. I designed the SEL Activities and conducted them with the participant students’ classroom teacher. I used phenomenological methods (Moustakas, 1994) to collect data through semi-structured interviews with primary school children who are 10-years-old and analysed the data by identifying significant statements and then clustering the significant statements into themes, writing textural and structural descriptions, before finally arriving at a composite description. Findings demonstrate that through the SEL Activities, the participant children became more competent in realizing the influence of emotions on their behaviours and in using practical and strategic knowledge on self-regulation skills.
