Archaeological Analysis

The three-dimensional (3D) revolution promised to transform archaeological practice. Of the technologies that contribute to the proliferation of 3D data, photogrammetry facilitates the rapid and inexpensive digitization of complex subjects in both field and lab settings. It finds additional use as a tool for public outreach, where it engages audiences ranging from source communities to artifact collectors. But what has photogrammetry's function been in advancing archaeological analysis? Drawing on our previous work, we review recent applications to understand the role of photogrammetry for contemporary archaeologists. Although photogrammetry is widely used as a visual aid, its analytical potential remains underdeveloped. Considering various scales of inquiry—graduating from objects to landscapes—we address how the technology fits within and expands existing documentation and data visualization routines, while evaluating the opportunity it presents for addressing archaeological questions and problems in innovative ways. We advance an agenda advocating that archaeologists move from proof-of-concept papers toward greater integration of photogrammetry with research.

Archaeological Analysis

MicroCT imaging is increasingly used in paleoanthropological and zooarchaeological research to analyse the internal microstructure of bone, replacing comparatively invasive and destructive methods. Consequently the analytical potential of this relatively new 3D imaging technology can be enhanced by developing discipline specific protocols for archaeological analysis. Here we examine how the microstructure of mammal bone changes after burning and explore if X-ray computed microtomography (microCT) can be used to obtain reliable information from burned specimens. We subjected domestic pig, roe deer, and red fox bones to burning at different temperatures and for different periods using an oven and an open fire. We observed significant changes in the three-dimensional microstructure of trabecular bone, suggesting that biomechanical studies or other analyses (for instance, determination of age-at-death) can be compromised by burning. In addition, bone subjected to very high temperatures (600°C or more) became cracked, posing challenges for quantifying characteristics of bone microstructure. Specimens burned at 600°C or greater temperatures, exhibit a characteristic criss-cross cracking pattern concentrated in the cortical region of the epiphyses. This feature, which can be readily observed on the surface of whole bone, could help the identification of heavily burned specimens that are small fragments, where color and surface texture are altered by diagenesis or weathering.

Role Of Information

Обґрунтована необхідність розширення культурологічних досліджень арт-ринку з урахуванням останніх культурно-мистецьких тенденцій, а також його наукової концептуалізації у вітчизняній культурології. Враховуючи зростання ролі інформації, арт-ринок набуває нових ціннісно-смислових аспектів, а інтерес до цієї теми потребує культурологічного осмислення. Інформаційна функція арт-ринку актуалізується завдяки формуванню і розвитку інформаційно-технологічної революції, тому має вплив на соціокультурну діяльність митців та презентацію їхнього мистецтва. Функцію інформування на арт-ринку виконують організаційні структури, серед яких виділено виставки та бієнале. Проаналізовано проєкти українських митців на першій Київській міжнародній бієнале сучасного мистецтва ARSENALE 2012 та проєкт Ж/ Кадирової під час 58 Венеційської бієнале у 2019 р. Ключові слова: арт-ринок, інформаційна функція, інформаційне суспільство, бієнале, Мистецький Арсенал, Арсенале 2012, Венеційське бієнале 2019. The necessity of expanding the cultural researches of the art market, taking into account the latest cultural and art tendencies, is considered, as well as its scientific conceptualization in national cultural studies. The art market is gaining new valuable and semantic meanings, because of the growing role of information. So the interest in this topic requires cultural reflection. The information function of this market is actualized due to the formation and the development of the digital revolution, so it has an impact on the socio-cultural activity of the artists and the presentation of their art. Information structures in the art market are performed by organizational structures, among which exhibitions and biennials are highlighted. The projects of Ukrainian artists from the first Kyiv International Biennale of Contemporary Art ARSENALE 2012 and the project of Zhanna Kadyrova from the 58th Venice Biennale in 2019 are analyzed. Key words: art market, informational function, information society, biennale, Mystetskyi Arsenal, ARSENALE 2012, Venice Biennale 2019.

Hox Protein

: HOX genes belong to the highly conserved homeobox superfamily, responsible for the regulation of various cellular processes that control cell homeostasis, from embryogenesis to carcinogenesis. The abnormal expression of HOX genes is observed in various cancers, including breast cancer; they act as oncogenes or as suppressors of cancer, according to context. In this review, we analyze HOX gene expression patterns in breast cancer and examine their relationship, based on the three-dimensional genome structure of the HOX locus. The presence of non-coding RNAs, embedded within the HOX cluster, and the role of these molecules in breast cancer have been reviewed. We further evaluate the characteristic activity of HOX protein in breast cancer and its therapeutic potential.

Ossifying fibroma (OF) is a rare, benign, fibro-osseous lesion of the jawbone characterised by replacement of the normal bone with fibrous tissue. The fibrous tissue shows varying amount of calcified structures resembling bone and/or cementum. The central variant of OF is rare, and shows predilection for mandible among the jawbone. Although it is classified as fibro-osseous lesion, it clinically behaves as a benign tumour and can grow to large size, causing bony swelling and facial asymmetry. This paper reports a case of large central OF of mandible in a 40-year-old male patient. The lesion was treated by segmental resection of mandible. Reconstruction of the surgical defect was done using avascular fibula bone graft. Role of three-dimensional printing of jaw and its benefits in surgical planning and reconstruction are also highlighted.

Postcolonial studies, postmodern studies, even posthuman studies emerge, and intellectuals demand that social sciences be remade to address fundamentals of the human condition, from human rights to global environmental crises. Since these fields owe so much to American state sponsorship, is it easier to reimagine the human and the modern than to properly measure the pervasive American influence? Reconsidering American Power offers trenchant studies by renowned scholars who reassess the role of the social sciences in the construction and upkeep of the Pax Americana and the influence of Pax Americana on the social sciences. With the thematic image for this enterprise as the ‘fiery hunt’ for Ahab’s whale, the contributors pursue realities behind the theories, and reconsider the real origins and motives of their fields with an eye on what will deter or repurpose the ‘fiery hunts’ to come, by offering a critical insider’s view.

The phenomenon of capillary imbibition through porous media is important both due to its applications in several disciplines as well as the involved fundamental flow physics in micro-nanoscales. In the present study, where a simple paper strip plays the role of a porous medium, we observe an extremely interesting and non-intuitive wicking or imbibition dynamics, through which we can separate water and dye particles by allowing the paper strip to come in contact with a dye solution. This result is extremely significant in the context of understanding paper-based microfluidics, and the manner in which the fundamental understanding of the capillary imbibition phenomenon in a porous medium can be used to devise a paper-based microfluidic separator.

This study examined if creating intimacy in a group discussion is more effective toward reaching consensus about climate change than a focus on information. Participants were randomly assigned to either a group that spent the first part of an online discussion engaging in self-disclosure and focusing on shared values (intimacy condition) or discussing information from an article about climate change (information condition). Afterward, all groups were given the same instructions to try to come to group consensus on their opinions about climate change. Participants in the intimacy condition had higher ratings of social cohesion, group attraction, task interdependence, and collective engagement and lower ratings of ostracism than the information condition. Intimacy groups were more likely to reach consensus, with ostracism and the emotional tone of discussion mediating this effect. Participants were more likely to change their opinion to reflect that climate change is real in the intimacy than information condition.

Abstract The gravitational charge algebra of generic asymptotically locally (A)dS spacetimes is derived in n dimensions. The analysis is performed in the Starobinsky/Fefferman-Graham gauge, without assuming any further boundary condition than the minimal falloffs for conformal compactification. In particular, the boundary structure is allowed to fluctuate and plays the role of source yielding some symplectic flux at the boundary. Using the holographic renormalization procedure, the divergences are removed from the symplectic structure, which leads to finite expressions. The charges associated with boundary diffeomorphisms are generically non-vanishing, non-integrable and not conserved, while those associated with boundary Weyl rescalings are non-vanishing only in odd dimensions due to the presence of Weyl anomalies in the dual theory. The charge algebra exhibits a field-dependent 2-cocycle in odd dimensions. When the general framework is restricted to three-dimensional asymptotically AdS spacetimes with Dirichlet boundary conditions, the 2-cocycle reduces to the Brown-Henneaux central extension. The analysis is also specified to leaky boundary conditions in asymptotically locally (A)dS spacetimes that lead to the Λ-BMS asymptotic symmetry group. In the flat limit, the latter contracts into the BMS group in n dimensions.
