This paper takes an exploratory look on control plane signaling in a mobile cellular core network. In contrast to most contributions in this field, our focus does not lie on the wireless or user-oriented parts of the network, but on signaling in the core network. In an investigation of core network data we take a look at statistics related to GTP tunnels and their signaling. Based on the results thereof we propose a definition of load at the GGSN and create an initial load queuing model. We find signs of user devices putting burden on the core network through their behavior.

AbstractThe 3GPP-based 5G System marks a clear departure form the previous generations. There is a new radio system and a complete overhaul of the core network design. The core network is redesigned both on the control plane parts and the transport plane. The control plane signalling within the core network is now largely based on the service based architecture (SBA) design, featuring Web-based technologies and the associated security solutions. In this paper we conduct a preliminary generic survey of threats to the SBA.

This article covers several stages of the work of Pichon-Rivière. In the 1950s he introduced the hypothesis of "the link as a four way relationship" (of reciprocal love and hate) between the baby and the mother. Clinical work with psychosis and psychosomatic disorders prompted him to examine how mental illness arises; its areas of expression, the degree of symbolisation, and the different fields of clinical observation. From the 1960s onwards, his experience with groups and families led him to explore a second path leading to "the voices of the link"—the voice of the internal family sub-group, and the place of the social and cultural voice where the link develops. This brought him to the definition of the link as a "bi-corporal and tri-personal structure". The author brings together the different levels of the analysis of the link, using as a clinical example the process of a psychoanalytic couple therapy with second generation descendants of a genocide within the limits of the transferential and countertransferential field. Body language (the core of the transgenerational link) and the couple's absences and presence during sessions create a rhythm that gives rise to an illusion, ultimately transforming the intersubjective link between the partners in the couple and with the analyst.

Обращаясь к рассмотрению вопроса о доминантно-функциональной структуреидиостиля, авторы раскрывают дефиницию «идиостиль» в его связи с экстра- и интралингвистическими факторами. Рассматривая творчество публициста М.Ф. Дороновича через призму одножанровых текстов, авторы выделяют доминанты, составляющие ядро идиостиля публициста. К числу таковых относятся оценочная метафоричность, гиперболичность, фразеологичность, реализующиеся как на уровне тропов, так и на уровне синтаксических фигур.Addressing the issue of dominant-functional structure of idiostyle, the authors reveal the definition of "idiostyle" in its connection with extra- and intralinguistic factors. Considering the creativity of the writer M.F. Doronovich through the lens of various genres of texts, the authors identify the dominant components of the core of the idiostyle of the writer. These include evaluative metaphoricity, hyperbolicity, phraseology, which are implemented both at the level of tropes and at the level of syntactic figures.СВЕДЕНИЯ О ГРАНТАХ И ФИНАНСИРОВАНИИИсследование подготовлено при поддержке Российского фонда фундаментальных исследований (отделение гуманитарных и общественных наук) и Министерства образования, науки и молодёжной политики Краснодарского края в рамках научного проекта № 18-412-230008 а(р) «Язык и стиль публикаций М.Ф.

For years, the gold-standard in academic publishing has been the peer-review process, and for the most part, peer-review remains a safeguard to authors publishing intentionally biased, misleading, and inaccurate information. Its purpose is to hold researchers accountable to the publishing standards of that field, including proper methodology, accurate literature reviews, etc. This presentation will establish the core tenants of peer-review, discuss if certain types of publications should be able to qualify as such, offer possible solutions, and discuss how this affects a librarian's reference interactions.

The definition of the multimorbidity concept reveals insufficient specificity of the comorbidity and multimorbidity definitions and, as a result, confusion in the use of these terms. Most authors are unanimous that the “core” of multimorbidity is presence of more than one disease in a patient. These coexisting diseases can be pathogenetically interconnected and non-interconnected. Regardless, the degree of multimorbidity always affects prognosis and quality of life.

AbstractHeterogeneous IoT-enabled networks generally accommodate both jitter tolerant and intolerant traffic. Optical Burst Switched (OBS) backbone networks handle the resultant volumes of such traffic by transmitting it in huge size chunks called bursts. Because of the lack of or limited buffering capabilities within the core network, burst contentions may frequently occur and thus affect overall supportable quality of service (QoS). Burst contention(s) in the core network is generally characterized by frequent burst losses as well as differential delays especially when traffic levels surge. Burst contention can be resolved in the core network by way of partial buffering using fiber delay lines (FDLs), wavelength conversion using wavelength converters (WCs) or deflection routing. In this paper, we assume that burst contention is resolved by way of deflecting contending bursts to other less congested paths even though this may lead to differential delays incurred by bursts as they traverse the network. This will contribute to undesirable jitter that may ultimately compromise overall QoS. Noting that jitter is mostly caused by deflection routing which itself is a result of poor wavelength and routing assigning, the paper proposes a controlled deflection routing (CDR) and wavelength assignment based scheme that allows the deflection of bursts to alternate paths only after controller buffer preset thresholds are surpassed. In this way, bursts (or burst fragments) intended for a common destination are always most likely to be routed on the same or least cost path end-to-end. We describe the scheme as well as compare its performance to other existing approaches. Overall, both analytical and simulation results show that the proposed scheme does lower both congestion (on deflection routes) as well as jitter, thus also improving throughput as well as avoiding congestion on deflection paths.

After stroke restricted to the primary motor cortex (M1), it is uncertain whether network reorganization associated with recovery involves the periinfarct or more remote regions. We studied 16 patients with focal M1 stroke and hand paresis. Motor function and resting-state MRI functional connectivity (FC) were assessed at three time points: acute (<10 days), early subacute (3 weeks), and late subacute (3 months). FC correlates of recovery were investigated at three spatial scales, (i) ipsilesional non-infarcted M1, (ii) core motor network (M1, premotor cortex (PMC), supplementary motor area (SMA), and primary somatosensory cortex), and (iii) extended motor network including all regions structurally connected to the upper limb representation of M1. Hand dexterity was impaired only in the acute phase ( P = 0.036). At a small spatial scale, clinical recovery was more frequently associated with connections involving ipsilesional non-infarcted M1 (Odds Ratio = 6.29; P = 0.036). At a larger scale, recovery correlated with increased FC strength in the core network compared to the extended motor network (rho = 0.71; P = 0.006). These results suggest that FC changes associated with motor improvement involve the perilesional M1 and do not extend beyond the core motor network. Core motor regions, and more specifically ipsilesional non-infarcted M1, could hence become primary targets for restorative therapies.

ABSTRACT The fundamental unit of biological diversity is the species. However, a remarkable extent of intraspecies diversity in bacteria was discovered by genome sequencing, and it reveals the need to develop clear criteria to group strains within a species. Two main types of analyses used to quantify intraspecies variation at the genome level are the average nucleotide identity (ANI), which detects the DNA conservation of the core genome, and the DNA content, which calculates the proportion of DNA shared by two genomes. Both estimates are based on BLAST alignments for the definition of DNA sequences common to the genome pair. Interestingly, however, results using these methods on intraspecies pairs are not well correlated. This prompted us to develop a genomic-distance index taking into account both criteria of diversity, which are based on DNA maximal unique matches (MUM) shared by two genomes. The values, called MUMi, for MUM index, correlate better with the ANI than with the DNA content. Moreover, the MUMi groups strains in a way that is congruent with routinely used multilocus sequence-typing trees, as well as with ANI-based trees. We used the MUMi to determine the relatedness of all available genome pairs at the species and genus levels. Our analysis reveals a certain consistency in the current notion of bacterial species, in that the bulk of intraspecies and intragenus values are clearly separable. It also confirms that some species are much more diverse than most. As the MUMi is fast to calculate, it offers the possibility of measuring genome distances on the whole database of available genomes.

Devoted to the theme of single-family houses, given the key role they played in the ideal definition of the Modern Movement architecture, as a symbolic and functional affirmation of the utopian turning of dreams into reality, the aim of this issue is to consider the transformation of daily life, and to address the architectural challenges that arose from the joy contained in what we might call the “architecture of happiness.” As we continue to endure a pandemic that has now lasted for more than a year, docomomo wishes to declare that “till the moment, the best vaccine to prevent contagion was invented by architects: the house”. Thus, in response to the question “How should we live?”, it is intended to debate the house and the home agenda as an important topic at the core of Modern Movement architecture. Nowadays, the growing emphasis on wellbeing goes beyond the seminal ideas that modern houses were “machines à habiter” and is closer to an idealistic vision of a stimulating shell for humans, which is shaped by imagination, experimentation, efficiency, and knowledge.

This chapter explores the fundamental vision of the human being at the core of Aquinas’ anthropology. Aquinas has typically been construed as defending a fundamentally ‘Aristotelian’ vision of the human being. I show that this label has generated a skewed reading of Aquinas. Accordingly, this chapter does not lay claim to identify what it would take for an anthropology to be authentically ‘Thomistic’. Instead, it makes a proposal concerning what I argue is the ‘guiding vision’ of Aquinas’ anthropology: namely the ‘distinctive unity of the human’. Aquinas prioritizes this notion of distinctive unity in the different areas of his anthropology. I explore how this distinctive unity is expressed (a) in Aquinas’ account of the human soul as the ‘horizon’ of the bodily and spiritual worlds, and (b) in his definition of the human being as ‘rational animal’.
