Attention Connect Network for Liver Tumor Segmentation from CT and MRI Images.

Introduction: Currently, the incidence of liver cancer is on the rise annually. Precise identification of liver tumors is crucial for clinicians to strategize the treatment and combat liver cancer. Thus far, liver tumor contours have been derived through labor-intensive and subjective manual labeling. Computers have gained widespread application in the realm of liver tumor segmentation. Nonetheless, liver tumor segmentation remains a formidable challenge owing to the diverse range of volumes, shapes, and image intensities encountered. Methods: In this article, we introduce an innovative solution called the attention connect network (AC-Net) designed for automated liver tumor segmentation. Building upon the U-shaped network architecture, our approach incorporates 2 critical attention modules: the axial attention module (AAM) and the vision transformer module (VTM), which replace conventional skip-connections to seamlessly integrate spatial features. The AAM facilitates feature fusion by computing axial attention across feature maps, while the VTM operates on the lowest resolution feature maps, employing multihead self-attention, and reshaping the output into a feature map for subsequent concatenation. Furthermore, we employ a specialized loss function tailored to our approach. Our methodology begins with pretraining AC-Net using the LiTS2017 dataset and subsequently fine-tunes it using computed tomography (CT) and magnetic resonance imaging (MRI) data sourced from Hubei Cancer Hospital. Results: The performance metrics for AC-Net on CT data are as follows: dice similarity coefficient (DSC) of 0.90, Jaccard coefficient (JC) of 0.82, recall of 0.92, average symmetric surface distance (ASSD) of 4.59, Hausdorff distance (HD) of 11.96, and precision of 0.89. For AC-Net on MRI data, the metrics are DSC of 0.80, JC of 0.70, recall of 0.82, ASSD of 7.58, HD of 30.26, and precision of 0.84. Conclusion: The comparative experiments highlight that AC-Net exhibits exceptional tumor recognition accuracy when tested on the Hubei Cancer Hospital dataset, demonstrating highly competitive performance for practical clinical applications. Furthermore, the ablation experiments provide conclusive evidence of the efficacy of each module proposed in this article.

This paper focuses on how individual actors form connection networks by reading Oh’s late poetry through the lens of Latour’s theory. In Oh’s poems, each of the poets plays the role of an actor. For example, “Tin Roof and Spring Rain” shows the aging and decline of a tin roof. The “scattered” and “crushed” bird droppings interact with the tin roof and promote its corrosion. As spring rain interacts with the tin roof, it washes away its surface and strips away the rust. If bird droppings are agents that bring about changes in the tin roof that accelerate
 corrosion, the spring rains are agents that bring about changes that delay this corrosion. Thus, the aging and decay of the tin roof, the presence of bird droppings, and the diversity of spring rains are all caused by the interaction of these actors. The biofilm is an experiential de facto Earth, where we live alongside other organisms in a very thin membrane, approximately the size of the Earth’s epidermis. Latour describes the critical zone as almost a biofilm. Both terms imply that there is only a small part of the Earth that humans can walk on and understand. Water and Road 1” and Water and Road 2” can also be interpreted as poems exploring the meaning of life and the change created by the interconnectedness of water, trees, and birds. What makes Oh's “Water and Road 2” so special is that it shows that the connections between actors in nature are not a given (such as the laws of nature), but the result of a struggle for survival between actors. Through this struggle, they form a network of connections and live in a biofilm, a thin and precious survival space created over the years.

Statistical match reports of the 2022 volleyball World Championship in the context of network analysis with Gephi

Background and Study Aim. Modern volleyball teams participating in tournaments provide extensive statistical data about their actions. These data are available for analysis and represent a valuable source for assessing the potential and future success of both individual athletes and teams as a whole. In this context, tools such as Gephi become particularly valuable for visualizing and analyzing events at high-level tournaments. Our study aims to create and analyze network models of interaction among men's volleyball teams during the qualifying matches of the 2022 World Championship using the Gephi software.
 Materials and Methods. For the research, data were obtained from a volleyball statistics website renowned for its extensive database. The study centered on Group C, comprising the teams: Poland, USA, Mexico, and Bulgaria. Data from six matches were extracted into Microsoft Excel tables and then converted into CSV format. The data from these tables were processed using the PyCharm programming environment and Python code. Visualization and analysis of the data were conducted using Gephi.
 Results. The results of the data processing highlight the professional expertise of the teams. The average values for all primary metrics underscore the teams' proficiency in executing fundamental actions at an elevated level. Eigenvector centrality helps determine the significance of nodes in the graph. The graph's density is 0.601, suggesting a relatively dense network of connections within the team. This indicates that volleyball players frequently engage with one another and share information on the court. Such extensive interaction can lead to enhanced coordination and efficiency in team actions. The parameter ε has a value of 1.0E-4, denoting high computational precision. The average interaction degree among volleyball players stands at 46.244. This measure denotes the interaction intensity among team members, hinting at the overall court activity. The modularity measure is 0.483, which signals the structural organization of the graph rooted in modularity. The graph comprises 5 modular communities, hinting at shared characteristics and cohesion among players within these groups. The HITS (Hyperlink-Induced Topic Search) metric assesses the node significance in the graph in terms of hubs and authorities. High HITS values pinpoint pivotal players acting as hubs, signifying their numerous connections with fellow teammates. Such players are crucial for facilitating information flow and coordination within the squad.
 Conclusions. Utilizing statistical match reports in volleyball, combined with the Gephi software, offers a deeper insight into the dynamics of player interactions. This aids in pinpointing key players, refining team strategies, and enhancing court coordination. Coaches are advised to leverage these tools for an in-depth evaluation of gameplay instances and to make informed decisions. Network analysis methodologies might soon be indispensable tools in the contemporary coaching toolkit.

The Absolute Capacity to be Killed and the Right to Life as Exemplified by the European Convention

The state remains the main arena of human existence and action. Woven from a dense network of political, economic, social and cultural connections, it dictates the conditions in which people are born, function and die. The decision whether individuals or their entire groups will live or die remains at the discretion of the arcana imperii. One of its manifestations is the use of the death penalty. The right to life, being the most important of the numerous catalogue of human rights, represents an institutional attempt to limit the powers of the state in this regard, an attempt which he has proven to be successful in the European space.

Tool Dichotomies in a Period of Inter-epochal Transition – Philosophical and Anthropological Reflections on Post-Neolithic Dual Technology

The presented publication is the end result of an authorial, post-doctoral research project devoted to the multi-aspect flint tool dichotomy at the turn of the Stone and Metal Ages. The results of use-wear analysis of archaeological materials from south-eastern Poland and the Moravia region of the Czech Republic, obtained by the author over the last decade, have been supplemented in this article with a philosophical component. By visualising the network of connections on the empirical-theory line, the explanatory value of the dichotomous lithic concept was raised. Moreover, the discourse on the period at the turn of the Stone and Metal Ages has been enriched with new interpretative solutions for economic and social issues of that time in prehistory. The author places his philosophical investigations within the hermeneutical approach. After the study of key terms (dichotomy, divergence, convergence), structuralist thought becomes the leading theme at the end of the article. The paper deals with the concepts of such thinkers as: Martin Heidegger, Hannah Arendt, and Claude Lévi-Strauss.

Investigation of microstructural, chemical bonding and optical properties of Fe-Cu/rGO nanocomposites

This work focuses on the synthesis of Iron – Copper with reduced graphene oxide (Fe-Cu/rGO) nanocomposites by chemical co-precipitation method and their characterizations by Scanning electron microscope (SEM), X-ray diffraction (XRD), Fourier transforms infrared (FTIR), Raman spectroscopy, UV visible spectroscopy and Energy dispersive X-ray (EDX) spectroscopy to investigate the morphology, structural, chemical bonding, optical characteristic and compositional study respectively. Within the Fe-Cu/rGO nanocomposites, the iron concentration ranged from 0 to 100 wt%, while the copper content changed reversibly from 100 to 0 wt% in a step of 20 wt%. SEM images reveal a connective network of grains that varies from 256 nm to 350 nm. The estimated crystallite size ranges from 15.2 nm to 71.3 nm. The micro-strain of Fe-Cu/rGO is altered from 0.00066 to 0.00347. Metal-Oxide (M-O) chemical bond is found shifting to a higher frequency with the addition of iron concentration indicating the increase in backing oxygen and carbon bonding with metal. The carbon defect parameter, ID/IG varied from 1.86 to 1.95 indicating microstructural modification and graphene cluster size decreases with the increase of copper content. The Tauc band gap decreased from 2.68 to 2.14 eV with increased copper content.

Il parlait assez bien français et plusieurs langues: Foreign Language Acquisition and the Diplomatic Self-Fashioning of Prince Boris Ivanovich Kurakin

Using the example of Prince B. I. Kurakin (1676–1727), the Imperial Russian diplomat who served as extraordinary and plenipotentiary ambassador to France (1724–1727), this article seeks to contribute to the ongoing discussion about the possible reasons for the adoption of French as the language of international communication in general and eighteenth-century diplomacy in particular. It asks when the Moscow-born Gediminid prince learned to speak French and how this non-native speaker of the language became proficient enough to impress a finicky and fastidious interlocutor like Louis de Rouvroy, duc de Saint-Simon (1675–1755). The author suggests that the answer to these questions lies not in Russia or France, but in Poland and Italy; and not in the halls of formal educational institutions, but in the networks of personal connections that were sustained as much by face-to-face communication as by written correspondence. This brief biographical survey of the development of Prince Kurakin’s “linguistic personality” demonstrates the mediating role of modern, vernacular languages (Russian, Polish, Italian) in the transition from Latin to French as the lingua franca of international diplomacy. It also emphasizes the intimate connection between foreign language acquisition and diplomatic self-fashioning, showing how linguistic knowledge could be instrumentalized for both personal and professional advancement. In doing so, it illustrates the active role that individual brokers – especially, but not exclusively, aristocratic royal servitors with broad linguistic skills and extensive international connections, like Prince Kurakin and the duc de Saint-Simon – played in creating the very notion of an early modern “European” style of diplomacy based on the cultural dominance of the French language.

Ciemnoekologiczna niebinarność na przykładach z poezji Łukasza Kaźmierczaka / Łucji Kuttig

My paper examines how the queer theme, particularly the issue of nonbinarity, is realized in Timothy Morton’s concept of dark ecology. The project of dark ecology assumes a mutual enmeshing of human and nonhuman beings, creating space for non-heteronormativity and non-cisgender, among other things. Dark ecology combines reflection that is feminist (e.g., by referring to the legacy of ecofeminists) and queer. It broadly describes the problems associated with binarism (not only gender binarism, but also that concerning the nature-culture dualisms that are foundational to Western reflection) and seeks an alternative in the aforementioned network of connections between all beings, which – as in Stacy Alaimo’s concept of transcorporeality or Donna Haraway’s sympoiesis – are interdependent. Dark ecology also proposes a practice of solidarity, which consists in accepting the common entanglement of all elements of the world in a catastrophe (which the author calls explicitly global warming) that is revolutionizing reality as we know it. The editors of <i>Disorientation. An Anthology of Polish Queer Literature</i> refer to Łukasz Kaźmierczak/Łucja Kuttig’s poems as non-binary poetry. In the author’s work, gender is fluid and, like other words, is subject to inflectional manipulation. The author touches on gender motifs directly and juxtaposes them with the problem of dichotomousness. In their texts, I am also interested in the issues of corporeality and the relationship of man with the environment (i.e., Morton’s mesh). Keywords: dark ecology, gender, queer studies, nonbinarity

Raw material trade and/or itinerant artisans? Data for a diachronic study of the trade in copper raw materials and finished products in the Carpathian Basin

AbstractCopper is one of the most important raw materials in the Carpathian Basin, and its extraction, processing and trade can be traced at least from the Bronze Age to the Middle Ages and beyond. Drawing on a variety of sources and research methods, the authors explore the patterns of distribution of this raw material in Europe. The aim of the diachronic analysis is to uncover the networks of connections – commercial, cultural, and migratory – that can be traced over the long term in the Central European region. It also draws attention to other, less stable links in the Carpathian Basin, which have also influenced the history of the region in certain periods.

Human-network regions as effective geographic units for disease mitigation

Susceptibility to infectious diseases such as COVID-19 depends on how those diseases spread. Many studies have examined the decrease in COVID-19 spread due to reduction in travel. However, less is known about how much functional geographic regions, which capture natural movements and social interactions, limit the spread of COVID-19. To determine boundaries between functional regions, we apply community-detection algorithms to large networks of mobility and social-media connections to construct geographic regions that reflect natural human movement and relationships at the county level in the coterminous United States. We measure COVID-19 case counts, case rates, and case-rate variations across adjacent counties and examine how often COVID-19 crosses the boundaries of these functional regions. We find that regions that we construct using GPS-trace networks and especially commute networks have the lowest COVID-19 case rates along the boundaries, so these regions may reflect natural partitions in COVID-19 transmission. Conversely, regions that we construct from geolocated Facebook friendships and Twitter connections yield less effective partitions. Our analysis reveals that regions that are derived from movement flows are more appropriate geographic units than states for making policy decisions about opening areas for activity, assessing vulnerability of populations, and allocating resources. Our insights are also relevant for policy decisions and public messaging in future emergency situations.

Treatment of preterm brain injury via gut-microbiota-metabolite-brain axis.

Brain injury in preterm infants potentially disrupts critical structural and functional connective networks in the brain. It is a major cause of neurological sequelae and developmental deficits in preterm infants. Interesting findings suggest that the gut microbiota (GM) and their metabolites contribute to the programming of the central nervous system (CNS) during developmental stages and may exert structural and functional effects throughout the lifespan. To summarize the existing knowledge of the potential mechanisms related to immune, endocrine, neural, and blood-brain barrier (BBB) mediated by GM and its metabolites in neural development and function. We review the recent literature and included 150 articles to summarize the mechanisms through which GM and their metabolites work on the nervous system. Potential health benefits and challenges of relevant treatments are also discussed. This review discusses the direct and indirect ways through which the GM may act on the nervous system. Treatment of preterm brain injury with GM or related derivatives, including probiotics, prebiotics, synbiotics, dietary interventions, and fecal transplants are also included. This review summarizes mechanisms underlying microbiota-gut-brain axis and novel therapeutic opportunities for neurological sequelae in preterm infants. Optimizing the initial colonization and microbiota development in preterm infants may represent a novel therapy to promote brain development and reduce long-term sequelae.

Subpopulations of corticotropin-releasing factor containing neurons and internal circuits in the chicken central extended amygdala.

In mammals, the central extended amygdala is critical for the regulation of the stress response. This regulation is extremely complex, involving multiple subpopulations of GABAergic neurons and complex networks of internal and external connections. Two neuron subpopulations expressing corticotropin-releasing factor (CRF), located in the central amygdala and the lateral bed nucleus of the stria terminalis (BSTL), play a key role in the long-term component of fear learning and in sustained fear responses akin to anxiety. Very little is known about the regulation of stress by the amygdala in nonmammals, hindering efforts for trying to improve animal welfare. In birds, one of the major problems relates to the high evolutionary divergence of the telencephalon, where the amygdala is located. In the present study, we aimed to investigate the presence of CRF neurons of the central extended amygdala in chicken and the local connections within this region. We found two major subpopulations of CRF cells in BSTL and the medial capsular central amygdala of chicken. Based on multiple labeling of CRF mRNA with different developmental transcription factors, all CRF neurons seem to originate within the telencephalon since they express Foxg1, and there are two subtypes with different embryonic origins that express Islet1 or Pax6. In addition, we demonstrated direct projections from Pax6 cells of the capsular central amygdala to BSTL and the oval central amygdala. We also found projections from Islet1 cells of the oval central amygdala to BSTL, which may constitute an indirect pathway for the regulation of BSTL output cells. Part of these projections may be mediated by CRF cells, in agreement with the expression of CRF receptors in both Ceov and BSTL. Our results show a complex organization of the central extended amygdala in chicken and open new venues for studying how different cells and circuits regulate stress in these animals.

The Difference and Application of VC and VD base on High-tech Enterprises

As a firm increases in size, it requires more money to cover a variety of activities such as large-scale product development, extending sales and marketing operations, purchasing assets, managing cash flow, and deferring the need for more equity financing. As a result, VC and VD are becoming increasingly significant. Venture capital and venture debt are critical sources of finance for startups and high-growth enterprises, allowing them to fuel development, gain expertise, and expand operations. Understanding the distinction between venture capital and venture debt allows entrepreneurs and company owners to better plan and manage their finances. They may weigh the costs, conditions, and consequences of each financing option to choose which best fits their business objectives, development plans, and risk tolerance. Venture capitalists not only supply firms with the financial resources they require, but they also frequently provide mentorship, industry experience, and access to a network of connections. Overall, understanding the distinction between venture capital and venture debt enables entrepreneurs and business owners to make educated financing decisions, customize their fundraising tactics, manage risks, and assure the long-term financial health and success of their company.

Graph neural network based robust anomaly detection at service level in SDN driven microservice system

Software-Defined Network (SDN) has been widely employed in data center networks to host various software systems such as microservice systems. A microservice system is constructed by a microservice architecture composed of dozens of services running in different lightweight virtual machines (e.g., containers) and relying on overlay networks for connectivity. However, with the increase of the system scale and the network traffic volume, the network becomes more complex and common to behave anomalously. Therefore, it is error-prone to manually investigate anomalies. To tackle this problem, we propose a non-intrusive monitoring system to help network operators obtain deep insights from the network traffic generated by the running system. Based on the monitoring system, we propose an anomaly detection method to automatically detect network anomalies. The core idea is to learn behavior patterns of inter/intra-components by modeling spatial–temporal relationships amongst collected network metrics with the proposed model STCell-VAE. The pattern will be leveraged to reconstruct the input data. Subsequently, the reconstruction probability is used to determine anomalies. Additionally, STCell-VAE can assimilate network information from new components as the network evolves, eliminating the necessity for retraining. Experiments are conducted within a real networking system and four simulated large-scale networks. The results demonstrate that our system can detect anomalies with about 0.7 F1-score, which outperforms state-of-the-art methods.

Kościelna księga rachunkowa z Szumiącej koło Kamienia Pomorskiego (1730–1792) – spojrzenie na źródło w oparciu o teorię aktora-sieci ANT i jego opis

Church accounting book from Szumiąca near Kamień Pomorski (1730–1792) – a look at the source and its description based on the ANT actor-network theory Eponymous church accounting book from Lutheran parish in Szumiąca near Kamień Pomorski from the years 1730–1792 was discovered in Gdańsk. The annual balance sheet was approved by the parish patrons. Control of parish books was coducted by praepositus of Chapter of Kamień. Research was undertaken with use of actor-network theory (ANT) corelated with timeline. Every person, institution, phenomenon, object or animal can become a network actor and create a network of connections. The book was placed in the church structures of the Kamień Chapter, an accounting system based on a combination of French and German accounting, and in the accounting currency system of that time. The graph presenting the Book as an actor-network shows the connections of accounting accounts with quantitative research, and accounting maxims with qualitative analyses. For a better understanding of the ANT theory adapted to historical research, the publication includes the results of an analysis of the purchasing power of silver contained in a good penny, taking into account inflation against the background of historical events. Accounting sentences describing people, places and events allowed for the analysis of connections with the resources of the State Archives in Szczecin.
