“This symposium marks the real beginning of observational cosmology”, Allan Sandage, 29 August 1986.It is a pleasure to be invited to attempt to summarise the very intense work of the last 6 days. Virtually all aspects of contemporary observational cosmology have been described and debated and it is my task to try to put this wealth of new material into context. As in all such surveys, allowance must be made for personal bias - like everyone else, I am sure I am giving an unbiased view but you must judge for yourselves!

The Mind

The article focuses on the novel “Pompeii” by Robert Dennis Harris which has been little studied in Russia and presents a new material for further research. The purpose of the research is to identify the originality of spatial images in the novel of the British writer. Basing on the comparative historical and analytical methods, the authors of the article explore the main principles of creating historical narration and the specifics of R.D. Harris’s work with historiographical sources while creating a historical epoch; they identify the features of W. Scott and E.G. Bulver-Lytton. Within the context of the study of the originality of spatial topoi in “Pompeii” the authors use extensively the concept of “topoekphrasis”, introduced by O.A. Kling. It distinguishes the place setting as a protagonist who influences greatly the course of events. While analyzing, the authors make the following conclusions about the national condition of the scene given by using ekphrasis and the correlation of the myth with the actual realities in the modern cultural system which indicate the stereotypical thinking of a person in the postmodern society: the myth of Adam and Eve who found themselves in Paradise, associated in the mind of a European with Capri which represents “unearthly” life; the expansion of the semantic fields after reading the myth of Sodom and Gomorrah which describes the destruction of two biblical cities and is brought closer in the novel to the events associated with the real tragedy in Pompeii, undoubtedly show the similarity of its plot resolution with the modern eschatological myth of the Apocalypse, which tells us about the inevitable death of civilization. The analysis of the mythological paradigm of R.D. Harris’s novel "Pompeii", organized by combination of ekphrasis and topoi, discloses the transformation of the postmodernist writer’s worldview, creating a new metaphysical reality in the historical novel. In addition to the real spatial topoi of the ancient world (forum, aqueduct, temple), the postmodern novel reveals mythological images: a labyrinth associated with the ancient Greek story of Theseus; the underground world of the dead, linked to the myth of Charon. The artistic understanding of the historical process by R.D. Harris allows us to identify the originality of the writer’s historical concept in the context of postmodern literature.

Direct Implementation

The study of novelty as a cultural phenomenon presupposes the formulation and solution of the problem in the ultimate interpretation, as an unbiased description of its appearance on a defined territory, reducing it to preestablished principles that explain novelty as certainty and stability. This means understanding the phenomenal limit-the novelty goes to infinity and shimmers in the vastness of being, appears to the inquisitive mind in the form of original discoveries and imaginary worlds. Novelty is revealed as the opening potency of being with the possibilities that have appeared – the reversal of events that are its direct implementation. The formulation of the novelty problem immediately confronts the initial contradiction and the difficulty of solving it. Imaginary novelty compensates for the unavailability of a material analog-it fills the voids of being and presence with its creations. Imaginary novelty carries the desired illusions that inspire the enthusiast, but under the cover of dreams, the real novelty of being grows. The paper suggests the related concepts: imaginative, imaginary, quasi-objective for the expansion of the intellectual landscape of the field of culture. In the aspect of novelty, the imaginary appears as an outstripping development of the presence, its separation from being and self-active bifurcation, the desire for a new material embodiment – the production of added being.

The Subject

When discussing in Troy: A Study in Homeric Geography the tribute of two maidens sent annually as temple-slaves to Athena at her temple in Ilion, I was able only to mention the existence of an inscription referring to the subject (pp. 131, 396). The inscription was then unpublished; I had been unable to obtain by correspondence any particulars other than an assurance that it contained no new material of importance.The inscription, discovered so long ago as 1896, and copied by Wilhelm in 1897, has at length appeared in the Jahreshefte des Oest. Arch. Institutes, xiv, dated 1911, but issued only in 1913. I have to thank Dr. Wilhelm for sending me a copy of his very full account and discussion (Die Lokrische Mädcheninschrift, pp. 163–256). I recur to the subject now because it seems to me that, contrary to my information, the inscription does throw a great deal of new light; and because, if I am not mistaken, the real significance of it has been entirely missed both by Dr. Wilhelm and by M. A. Reinach—unhappily lost to science in the battle of the Marne two years ago—who discussed it in the Revue de l'Histoire des Religions, lxix, 1 (Jan. 1914), pp. 12–54.

The time-varying data of air temperatures experienced by people in their daily lives is an important basis for studying human thermal sensation, adaptation, comfort, and health. It is also very important for designing targeted strategies to help people reduce uncomfortable experience. In this study, a small (98 mm × 49 mm × 25 mm), lightweight (~100 g), and portable temperature logger with a wide measurement range (−40 to 100 °C) and appropriate accuracy (±0.3 °C precision) was combined with a phone holder that was adapted as an armband sleeve to constitute a wearable monitor. Fourteen monitors were worn by 14 residents in 6 different households in rural Beijing, China, to monitor their personal thermal environment. In the context of having very similar living habits in winter and coping strategies for thermal discomfort, the temperatures that 14 residents experienced exhibited wide ranges and large variations during the two-day test period. The highest and lowest temperatures experienced by residents reached 30.6 and −16.6 °C, respectively. This paper provided new data and evidences about various temperatures experienced by residents, even though they were from the same family and lived together for decades. In terms of methodology, as an exploration, the present study indicated that using personal wearable monitors is a viable method to capture the real experienced thermal environment, which extended the method for collecting data regarding complex experiences in different environments to aid the study of human responses to the real-world thermal environment.

Abstract Background Parechoviruses (PeV-As), which constitute a new genus within the family Picornaviridae, have been associated with numerous localized outbreaks of serious diseases, such as coryza, pneumonia, maculopapular exanthem, and conjunctivitis. However, only a few laboratories worldwide routinely conduct tests for the identification of this group of viruses; presently, to the best of our knowledge, no laboratory in China conducts routine test for PeV-A identification. Therefore, in this study, we aimed to develop and validate a real-time RT-PCR assay for the identification of PeV-As. Methods To designed and validate a real-time PCR primer-probe targeting the 5′-UTR region of PeV-As, the 5′-UTR sequences of PeV-As available in GenBank were aligned using the MUSCLE algorithm in MEGA v7.0. Thereafter, the highly conserved 5′-UTR region was selected, and its primer-probe sequence was designed using Primer Premier v5.0. This primer-probe sequence was then evaluated for specificity, sensitivity, and repeatability, and for its validation, it was tested using fecal samples from 728 healthy children living in Beijing (China). Results The PeV-A real-time RT-PCR assay detected only the RNA-positive standards of PeV-A genotypes (1–8, 14, 17, and 18), whereas 72 serotypes of non-PeV-A EV viruses were undetected. In addition, the VP1 region of these 11 PeV-A genotypes that tested positive were amplified using the primers designed in this study. Typing results indicated that eight, one, and two strains of the 11 were PeV-A1, PeV-A4, and PeV-A6, respectively. We also determined and presented the genetic characterization and phylogenetic analyses results corresponding to these 11 VP1 region sequences. Furthermore, the real-time RT-PCR assay showed good repeatability, reproducibility, and sensitivity. Conclusion Our findings suggested that the real-time RT-PCR assay developed in this study can be applied for routine PeV-A identification. Additionally, we believe that our results will serve as a foundation for further studies on PeV-As and facilitate the expansion of the gene sequence information available in GenBank.

Recently with the increase in advanced age population, the osteoporosis becomes the object of public attention in the field of orthopedics. The surface topography of the bone by scanning electron microscopy (SEM) is one of the most useful means to study the bone metabolism, that is considered to make clear the mechanism of the osteoporosis. Until today many specimen preparation methods for SEM have been reported. They are roughly classified into two; the anorganic preparation and the simple preparation. The former is suitable for observing mineralization, but has the demerit that the real surface of the bone can not be observed and, moreover, the samples prepared by this method are extremely fragile especially in the case of osteoporosis. On the other hand, the latter has the merit that the real information of the bone surface can be obtained, though it is difficult to recognize the functional situation of the bone.

For small curvatures of a graphitic sheet, carbon atoms can maintain their preferred sp2 bonding while allowing the sheet to have various three-dimensional geometries, which may have exotic structural and electronic properties. In addition the fivefold rings will lead to a positive Gaussian curvature in the hexagonal network, and the sevenfold rings cause a negative one. By combining these sevenfold and fivefold rings with sixfold rings, it is possible to construct complicated carbon sp2 networks. Because it is much easier to introduce pentagons and heptagons into the single-layer hexagonal network than into the multilayer network, the complicated morphologies would be more common in the single-layer graphite structures. In this contribution, we report the observation and characterization of a new material of monolayer graphitic structure by electron diffraction, HREM, EELS.The synthesis process used in this study is reported early. We utilized a composite anode of graphite and copper for arc evaporation in helium.

Thick Medium

TEM characterization and microanalysis of the recording media is crucial and complementary to new material system development as well as quality control applications. Due to the type of material generally used for supporting the medium, i.e., a polymer, conventional macro- and microthinning procedures for thin foil preparation are not applicable. Ultramicrotorny (UM) is a viable option and has been employed in previous similar studies. In this work UM has been used for preparation of XTEM samples from a magneto-optical (MO) recording medium in its original production format.The as-received material system consisted of a 4-layer, 2100 Å thick medium including a 300 Å TbFeCo layer enveloped by silicon nitride protective layers supported on a 1.2 mm thick × 135 mm (5.25 in.) diameter polycarbonate disk. Recording tracks had an approximate pitch of 1.6 μm separated by 800 Å deep peripheral grooves. Using a Buehler Isomet low-speed diamond saw, 1 mm wide and 20 mm long strips were cut out of the disk along the recording tracks.
