Abstract Syrgiannes Palaiologos Philanthropenos played a leading role in the conflicts between factions of the Byzantine aristocracy in the 1320s and 1330s. The most important historians of the period, Nikephoros Gregoras and John Kantakouzenos, depict a rather negative picture of the personality of Syrgiannes. He is portrayed as an overambitious individual who constantly plots against the throne. He is seen as a perjurer whose actions prove that he has no moral constraints and does not hesitate to betray his friends. This image has influenced modern scholarship which to a large extent uncritically accepts this negative image of Syrgiannes without taking into consideration the biases and contradictions of the narratives of Gregoras and Kantakouzenos. The cross-examination of the information provided by these two historians indicates that a large part of their account of the activities of Syrgiannes and his motives should be treated cautiously.

The article identifies the main risks and threats related to national and international psychological security (PS) in BRICS countries (particularly China, India, and Russia) and posed by the malicious use of artificial intelligence (AI). The main methods of research are systemic, scenario, and case analyses. The authors maintain that PS threats, both national and international, created by the malicious use of AI should be considered at three levels. At the first level, a false negative image of AI is spread. The second level of PS threats is directly related to the malicious use of AI (MUAI), but an attack on public consciousness is not its main goal. The MUAI designed primarily to cause psychological damage belongs to the third, and highest, level of PS threats. Synthetic AI products (combining a number of technologies, which can increase the damage from their hacking or malicious use) create a whole range of new risks and threats to BRICS countries. The reorientation of commercial AI systems, the malicious use of deepfakes and chatbots, the use of bots to set agendas, deranking, and AI phishing technologies also pose a threat. The main methods of destructive impact through MUAI are illustrated by the examples China, India, and Russia. BRICS policy documents state readiness for joint action against the MUAI. At this point bilateral agreements play the leading role in the development of AI cooperation of BRICS member states, but their declarations clearly state the intention to join forces against the misuse of information and communications technology (ICT). National regulation pertaining to AI and efforts to counter its malicious use are still at the fledgling stage in most countries. This makes it all the more important for each of the BRICS member states to develop international cooperation and share experience. BRICS’s potential in this sphere is still very far from being fully tapped.

The paper offers to extend the historical time frame of modern cross-media studies formation. The start of this research direction dates not from the 1950-60s, as it is usually considered to be, but from the early 20th century, the ‘synthesis epoch’. Development of neosyncretism was accompanied by creating bright theories in aesthetics and art criticism and promoting the concept of arts’ interaction by the humanities. Three scholars — H. Wolfin, M. Dessoir, and A. Warburg were the pioneers of the modern interdisciplinary research field. The author considers that the range of influences on the cross-media studies in literary criticism should be broadened with the works of philosophers and art critics who started to use the cross-media strategies (not the term itself) when analyzing the works of literature and arts. The leading role belonged to the Iconology school (E. Panofsky, R. Wittkower, E. Gombrich et al.). Their methods were based on applying tools of various disciplines. In the first place, they took into account connections between literature and visual arts. Henceforth, philology interpolated the iconological method into visual and comparative studies. One of the contemporary leading cross-media researchers, W. J. T. Mitchell, named his first book “Iconology: Image, Text, Ideology” (1986). In the middle of the 20th century, philosophy had a considerable influence on the cross-media research formation. In particular, literary critics referred to phenomenology (the works by M. Dufrenne, R. Ingarden. M. Merleau-Ponty) and actualized the analysis of interacting arts once more. A visual turn in culture caused growing attention to the issues of apperceptive cross-sensual experience. The newest works in the fields of perception psychology, gestalt psychology, neurolinguistics, and neurophysiology also support the general cross-media theory. It is possible that, due to the mutual influences of sciences, a uniform platform for studying syncretic phenomena will be created.

Previously we reported that tannic acid is a very effective fixative for proteins including polypeptides. Especially, in the cross section of microtubules, thirteen submits in A-tubule and eleven in B-tubule could be observed very clearly. An elastic fiber could be demonstrated very clearly, as an electron opaque, homogeneous fiber. However, tannic acid did not penetrate into the deep portion of the tissue-block. So we tried Catechin. This shows almost the same chemical natures as that of proteins, as tannic acid. Moreover, we thought that catechin should have two active-reaction sites, one is phenol,and the other is catechole. Catechole site should react with osmium, to make Os- black. Phenol-site should react with peroxidase existing perhydroxide.

During the earliest stage of oocyte development in the limpet, Acmea scutum, Golgi complexes are small, few and randomly dispersed in the cytoplasm. As growth proceeds, the Golgi complexes increase in size and number and migrate to the periphery of the cell. At this time, fibrous structures resembling striated rootlets occur associated with the Golgi complexes. Only one fibrous structure appears to be associated with a Golgi complex.The fibers are periodically cross banded with an average of 4 dense fibrils and 6 lighter fibrils per period (Fig. 1). The cross fibrils have a center to center spacing of about 7 run which appears to be the same as that of the striated rootlets of the gill cilia in this animal.

Considerable and continuing interest has been shown in the thin film transducer fabrication for surface acoustic waves (SAW) in the past few years. Due to the high degree of miniaturization, compatibility with silicon integrated circuit technology, simplicity and ease of design, this new technology has played an important role in the design of new devices for communications and signal processing. Among the commonly used piezoelectric thin films, ZnO generally yields superior electromechanical properties and is expected to play a leading role in the development of SAW devices.

The energy distribution in an electron; beam from an electron gun provided with a biased Wehnelt cylinder was measured by a retarding potential analyser. All the measurements were carried out with a beam of small angular divergence (<3xl0-4 rad) to eliminate the apparent increase of energy width as pointed out by Ichinokawa.The cross section of the beam from a gun with a tungsten hairpin cathode varies as shown in Fig.1a with the bias voltage Vg. The central part of the beam was analysed. An example of the integral curve as well as the energy spectrum is shown in Fig.2. The integral width of the spectrum ΔEi varies with Vg as shown in Fig.1b The width ΔEi is smaller than the Maxwellian width near the cut-off. As |Vg| is decreased, ΔEi increases beyond the Maxwellian width, reaches a maximum and then decreases. Note that the cross section of the beam enlarges with decreasing |Vg|.

The only form of cellulose which could unequivocally be ascribed to the animal kingdom is the tunicin that occurs in the tests of the tunicates. Recently, high-resolution solid-state l3C NMR revealed that tunicin belongs to the Iβ form of cellulose as opposed to the Iα form found in Valonia and bacterial celluloses. The high perfection of the tunicin crystallites led us to study its crosssectional shape and to compare it with the shape of those in Valonia ventricosa (V.v.), the goal being to relate the cross-section of cellulose crystallites with the two allomorphs Iα and Iβ.In the present work the source of tunicin was the test of the ascidian Halocvnthia papillosa (H.p.). Diffraction contrast imaging in the bright field mode was applied on ultrathin sections of the V.v. cell wall and H.p. test with cellulose crystallites perpendicular to the plane of the sections. The electron microscope, a Philips 400T, was operated at 120 kV in a low intensity beam condition.

Health Model

Emerging adulthood is a time of instability. This longitudinal study investigated the relationship between mental health and need satisfaction among emerging adults over a period of five years and focused on gender-specific differences. Two possible causal models were examined: (1) the mental health model, which predicts that incongruence is due to the presence of impaired mental health at an earlier point in time; (2) the consistency model, which predicts that impaired mental health is due to a higher level of incongruence reported at an earlier point in time. Emerging adults (N = 1,017) aged 18–24 completed computer-assisted telephone interviews in 2003 (T1), 2005 (T2), and 2008 (T3). The results indicate that better mental health at T1 predicts a lower level of incongruence two years later (T2), when prior level of incongruence is controlled for. The same cross-lagged effect is shown for T3. However, the cross-lagged paths from incongruence to mental health are marginally associated when prior mental health is controlled for. No gender differences were found in the cross-lagged model. The results support the mental health model and show that incongruence does not have a long-lasting negative effect on mental health. The results highlight the importance of identifying emerging adults with poor mental health early to provide support regarding need satisfaction.
