The Characteristics, Harm and Anti-monopoly Measures of Digital Enterprise Monopolistic Behavior in Digital Economy: A Case Study of Amazon
Authors: Liu Hongfu 
Published: June 2024

With the wave of artificial intelligence, blockchain, cloud computing, big data and other digital technologies becoming new general technologies, digital enterprises present new characteristics of industrial organization: non-contest-ability of information products, zero marginal cost of information, digital market can be absent online, and big data can replace material materials as key inputs. These new characteristics lead to some new types of monopolistic behaviors in digital enterprises. This paper selects the self-preferential behavior for detailed analysis, and takes the well-known digital enterprise Amazon platform as an example: (1) summarizes the foundation (development mode) of realizing self-preferential behavior; (2) the whole chain of self-preferential treatment behavior from pricing, product selection, procurement, after-sales and inventory; (3) It points out four kinds of behaviors that are harmful to competition, such as weakening competitors' advantages, increasing competitors' costs, reducing innovation motivation and damaging consumers' welfare. Finally, this paper provides a reference for the monopoly identification of this behavior from three aspects: expanding the identification of digital economy market, refining the standards for identifying dominant market position, and carefully identifying the abuse of dominant market position by self-preferential treatment, and further puts forward regulatory suggestions.

Abstract
Rheumatoid arthritis (RA) is a complex autoimmune disease that leads to joint destruction. A number of immune cells that affect joint tissues are involved in the pathogenesis of this disease. This leads to the synthesis of many pro-inflammatory mediators. The transport of drugs, as well as many cytokines involved in the development of inflammation in RA patients, is mediated by membrane transporters. Membrane transporters are proteins that mediate the transfer of substrates across biological membranes. But to date there are no studies examining the expression of solute carrier (SLC) transporters in joint tissues. The aim of the study was to evaluate the expression of individual SLC family transporters in the synovial membranes (SMs) and infrapatellar fat pad (Hoffa’s pad) of RA patients. The study included 20 patients with rheumatoid arthritis and 20 with osteoarthritis as the control group who were undergoing joint replacement surgery as a normal part of clinical care. In the SM and Hoffa’s pad of RA patients the following 17 membrane transporters were defined at relevant expression levels for SLC transporter superfamily: SLC15A2, SLC16A3, SLC19A1, SLC2A9, SLC22A1, SLC22A3, SLC22A4, SLC22A5, SLC22A18, SLC33A1, SLC47A1, SLC51A, SLC7A5, SLC7A6, SLC01C1, SLC02B1, SLC04A1. The confirmed expression of these transporters in the SMs as well as Hoffa’s pad of patients with RA and OA, and the differences in their expression between these groups, suggests the involvement of SLC transporters in both the maintenance of homeostasis under physiological conditions in the tissues of the joints, as well as in the inflammatory process in RA.
Securing Decentralized Storage in Blockchain: A Hybrid Cryptographic Framework
Authors: Swati Jadhav , Nitin Pise 
Published: June 2024

Abstract
The evolution of decentralized storage, propelled by blockchain advancements, has revolutionized data management. This paper focuses on content security in the InterPlanetary File System (IPFS), a leading decentralized storage network lacking inherent content encryption. To address this vulnerability, we propose a novel hybrid cryptographic algorithm, merging AES 128-bit encryption with Elliptic Curve Cryptography (ECC) key generation. The algorithm includes ECC key pairs, random IV generation, and content/AES key encryption using ECC public keys. Benchmarking against standard AES 256-bit methods shows a significant 20% acceleration in encryption speed and a 16% increase in decryption efficiency, affirming practicality for enhancing IPFS content security. This research contributes to securing decentralized storage and provides a performance-driven solution. The promising results highlight the viability of the proposed approach, advancing understanding and mitigating security concerns in IPFS and similar systems.
An Improved Parallel Biobjective Hybrid Real-Coded Genetic Algorithm with Clustering-Based Selection
Authors: Akopov Andranik S. 
Published: June 2024

Abstract
This work presents an improved parallel biobjective hybrid real-coded genetic algorithm (MORCGA-MOPSO-II). The approach is based on the combined use of the parallel Multi-Objective Real-Coded Genetic Algorithm (MORCGA) and the Multi-Objective Particle Swarm Optimization (MOPSO). At the same time, clustering-based selection techniques are used to form subpopulations of parent individuals. Using well-known clustering algorithms (e.g., k-Means, hierarchical clustering, c-means, and DBSCAN) in combination with the proposed clustering-based mutation (the CL-mutation) directed toward the obtained cluster centers allows for improving the quality of the Pareto fronts’ approximations. The results of the MORCGA-MOPSO-II were compared with other well-known multi-objective evolutionary algorithms (e.g., SPEA2, NSGA-II, FCGA, MOSPO, etc.). Moreover, the MORCGA-MOPSO-II was integrated with the previously developed agent-based model of a goods exchange through the objective functions. As a result, the Pareto fronts have been obtained for the agent-based model of a goods exchange in different configurations of the initial distribution of agents.

Published: June 2024

Abstract
An efficient face recognition system is essential for security and authentication-based applications. However, real-time face recognition systems have a few significant concerns, including face pose orientations. In the last decade, numerous solutions have been introduced to estimate distinct face pose orientations. Nevertheless, these solutions must be adequately addressed for the three main face pose orientations: Yaw, Pitch, and Roll. This paper proposed a novel deep transfer learning-based multitasking approach for solving three integrated tasks, i.e., face detection, landmarks detection, and face pose estimation. The face pose variation vulnerability has been intensely investigated here underlying three modules: image preprocessing, feature extraction module through deep transfer learning, and regression module for estimating the face poses. The experiments are performed on the well-known benchmark dataset Annotated Faces in the Wild (AFW). We evaluate the outcomes of the experiments to reveal that our proposed approach is superior to other recently available solutions.

Abstract
In mammals, the pregnant female carries many physiological and anatomical changes. Biochemical profiles are very important tools for monitoring gestation progress. This study was designed to investigate pregnancy-related changes of blood metabolites in Ouled Djellal ewes under semi-arid conditions. Blood samples were collected from ten non pregnant multiparous ewes 4 weeks before conception and 4, 12 and 18 weeks of pregnancy age. The pattern of changes of some biochemical parameters were studied. Cholesterol level showed no significant changes during pregnancy, while triglyceride, AST and Ca decreased up to the 12th week of pregnancy, whereas the total protein, albumin, and creatinine increased toward the 12th week of pregnancy. Urea reached maximum levels at the end of the pregnancy, contrary to ALT that was significantly decreased. Glucose concentration showed a continual decrease varying from 2.08 ± 0.78 g.l−1 at the first month of pregnancy to 0.35 ± 0.36 g.l−1 at the 18th week of pregnancy. On the other hand, pregnancy establishment increased significantly the glucose, triglyceride, albumin, and urea, but it decreased significantly the cholesterol and creatinine levels. No differences were observed between pregnant and non-pregnant ewe for the rest of the parameters. These results demonstrated a clear evidence of pregnancy-related distribution of blood biochemical indices of Ouled Djellal ewe under semi-arid conditions. Some substrates and enzymes were mainly higher during the first half of pregnancy (triglyceride, AST and Ca), and some others increased from the mild pregnancy period (total protein, albumin and creatinine), while urea and ALT changes were observed at late pregnancy. The energetic demand increased with advancing pregnancy.

Abstract
A great interest is placed on the influence of probiotic, prebiotic and synbiotic preparations on animals in accordance with the principle of One health. The small intestine mucosa represents a complex ecosystem ensuring the homeostasis of the animal organism. The effect of Lacto-Immuno-Vital synbiotic preparation on the quantity of mucin produced in the broiler chicken small intestine was studied. The chickens (7 days old Hybrid ROSS 308) were divided into 3 equal size (n = 16) groups, housed in separate halls: control group (CG), and two experimental groups that received syn-biotic preparation Lacto-Immuno-Vital, – one with continuous synbiotic administration (EGC), and another with pulsed synbiotic administration (EGP). The preparation was administered to EGC group from the experimental day 1 to day 7 continuously every day (500 g per 1000 l of drinking water.day−1), and to EGP group from experimental day 8 to day 22 in a pulsed manner (every third day) at a dose of 300 g per 1000 l of drinking water. The experiment lasted 22 days. A significant effect on mucus production quantity was found in the duodenum (P < 0.001), in EG after both types of synbiotic supplementation compared to CG. The comparison of continuous and pulsed supplementation was as follows: a significant effect (P < 0.001) was observed after continuous supplementation of the synbiotic preparation, compared to pulsed supplementation in EG.
Fenye by the Numbers: A Quantitative Analysis of Astrological Contents in Chinese Local Gazetteers
Authors: Chen Shih-Pei 
Published: June 2024

Abstract

Fenye (分野, lit., “field allocation”), is a traditional Chinese astrological system that associated celestial phenomena with regions on earth since ancient times. During middle and late imperial China, many literati writings criticized this system as illogical. Yet in the local gazetteers that were compiled in late imperial China to document local data within each administrative region, compilers continued to use fenye as the canonical way to identify their regions within the vast empire. The Jesuit introduction of Western sciences to China, in particular the technology that could precisely locate any place or region with latitude and longitude, appeared to render fenye obsolete, which fueled even more literati criticism. Modern scholars consider the public criticism from the Qianlong emperor and the resulting removal of fenye from the 1781 Rehe Gazetteer the end of fenye in imperial orthodoxy. However, by quantitatively analyzing a collection of 4,410 titles of local gazetteers and their section headings, this paper reveals many examples of local literati who resisted removing fenye entirely from their local history, well into the late Republican period.
An Encounter of Incommensurables: European Cosmological Knowledge in the Fenye Chapters of Chinese Local Gazetteers (1660-1820)
Authors: Wu Huiyi 
Published: June 2024

Abstract
It has often been argued that the introduction of early modern European cosmology at the turn of the seventeenth century by Jesuit missionaries—subsumed under the generic term “Western learning” (xixue 西學)—signalled the demise of traditional fenye (分野, or “field allocation”) theory, as the concept of Earth’s sphericity and the widened sense of world geography are fundamentally at odds with the Sinocentric worldview underpinning fenye. However, the fenye chapters in Qing dynasty local gazetteers tell a different story: in comparison with earlier Ming gazetteers their proportion increased. These chapters rarely take a stance against Western learning. Rather, they invoke Western learning as part and parcel of the imperially sanctioned astronomy to be reckoned with, or even suggest it as a remedy for flaws in traditional fenye techniques, leading to a plurality of discourses in which Sino-Western relationships become entangled with tension between the imperial and the local. This phenomenon is particularly visible in the peripheral regions of the empire, such as Guangxi, as these were traditionally marginalised in the Sinocentric cosmology of the fenye system. This paper explores cosmological discourses to answer the following questions: What were the agendas that Western learning was made to serve in these gazetteers? How did local endeavours relate to court-sponsored imperial projects? What were their sources of knowledge on matters of Western learning, and how can we map out the geography of Western learning based on these local sources?
From Fenye to Fengshui: Applying Correlative Cosmography in Late Imperial China
Authors: Brown Tristan G. 
Published: June 2024

Abstract
This paper documents the resilience of fenye (分野, lit., “field allocation”) and its applications through the nineteenth century in China. Despite literati (and eventually imperial) criticisms that the fenye system of correlative cosmography was outdated and unworthy of belief, fenye retained a sizeable audience through the close of the Qing period. At the top, the Qing imperial state continued to reference fenye correlations in its official communications late into the dynasty. In local society, literati looked to newly issued dynastic sources of astrological knowledge to update local gazetteers; in the nineteenth century, these trends were pronounced along frontier areas lacking longstanding gazetteer records. Finally, people engaged in the practice of fengshui looked to fenye knowledge to update the values and layout of the compass, the historical origins of which related to geomantic practices. In the Qing period, the compass was both theoretically and physically altered under the influence of Jesuit-introduced “Western Learning” (Xixue 西學). The paper contends that the status of fenye in pre-twentieth century China was seldom an allor-nothing proposition between a celebrated component of imperial orthodoxy and an outdated relic in inexorable decline: people critiqued fenye, used fenye, and updated fenye.
From Fenye to Latitude and Longitude: The Adjustment and Renewal of the Positioning System in Chinese Local Gazetteers during Qing Dynasty
Authors: Zhang Jiajing 
Published: June 2024

Abstract
Influenced by a cosmological view of the interconnectedness between heaven and humankind, ancient Chinese astrologers developed the fenye (分野, “field allocation”) system. This theory envisioned correspondence between heaven and earth and was a prevalent regional positioning system in ancient China. However, during the Qianlong era (1736-1796), fenye theory faced skepticism and rejection from official quarters, leading to a significant crisis for this traditional positioning system. With the eastward spread of Western learning, modern European astronomical and geographical knowledge were introduced into China, and Chinese intellectuals began to favor the Western system of latitude and longitude for geographical positioning. In the late Qing period, the gradual popularization of the spherical Earth concept and the latitude and longitude system laid the theoretical foundation for establishing of this system. The public dissemination of latitude and longitude data measured by the imperial astronomical and calendrical institutions, along with mathematicians’ calculations based on historical data and the supplementary measurements conducted by local governments, provided data support for the system’s establishment. By the end of the Qing dynasty, as the knowledge structures and worldviews of Chinese intellectuals transformed, the traditional celestial-terrestrial correspondence in Chinese local gazetteers was phased out, giving way to the latitude and longitude system.
From the “dirty port” to the Disinfection Service of the Port of Rio de Janeiro (1893-1911)
Authors: Mantuano Thiago 
Published: June 2024

Abstract
This article demonstrates how sanitation was one of the many issues that led to the heavy opposition to the operation of the Port of Rio de Janeiro, at the end of the nineteenth century. Aside from the historiographical framework that centers on the movement of people and objects through ports as a threat to public health at that time, the aim was to clarify how the port itself and its infrastructures were considered hazardous and unsanitary and how the sanitation defense procedures were found to be inadequate and ineffective. The evidence presented here points to the destruction-construction of the Port of Rio de Janeiro, in the early twentieth century, as a solution to radically transform its infrastructure. The port under construction was consonant with the full technical-technological implementation of the “disinfection” service, which both supported its new operation and helped solve the public health issues afflicting the city.

Published: June 2024

Abstract
This study aimed to assess the effect of botanical and geographical differences on the protein, minerals, total phenolic content and the antioxidant activity of bee pollen collected from five districts in West Shewa Zone, Ethiopia. Pollens of Guizotia sp., Brassica sp., Trifolium sp., Eucalyptus sp., Plantago lanceolata and Vicia faba were color-sorted from multifloral pollens and subjected to chemical analysis. The results revealed the mean content of moisture 10.6% of fresh weight (FW), protein 19.4% of dry weight (DW) and ash 2.4% (DW); the most dominant minerals, K (9765.6), Ca (963.4), Mg (960.5), Fe (142.8) and P (126.5) in mg/kg DW. The average of the total phenolic content (TPC) and the antioxidant activity (DPPH radical) were 40.3 GAE mg/g FW and 13.7 AAE mg/g FW (gallic and ascorbic acid equivalent, respectively). V. faba pollen had the highest protein, ash, P and Cu content. Four pollen taxa had the highest Ca values, while multifloral pollens contained the highest Fe content. The samples from Ejere had the highest ash, Ca, Na and Cu content. The results showed a high content of the tested chemicals and a strong antioxidant capacity of bee pollen, varying with botanical and geographical origins. These findings would also serve as inputs for further assessment of the nutritional values of pollen for honey bee colonies and potential human consumption. However, comprehensive chemical investigations of larger number of samples representing diversified flora and locations are crucial to developing a broad regional information base on the nutritional profile of bee pollen.
An Autopsy Case of Acute Transformation of Myelodysplastic Syndrome Leading to Carcinomatous Cardiac Tamponade
Authors: Hatakeyama Junji , Ageishi Ryo , Kato Fumito 
Published: June 2024

Abstract

Introduction
We report a rare case of an 80-year-old male patient with acute transformation of myelodysplastic syndrome (MDS) in the pericardial cavity, leading to cardiac tamponade.

Case presentation
The patient had been diagnosed with MDS 7 months prior. One day before presentation, he suddenly developed dyspnea. At presentation, his blood pressure was stable, but he was in tachycardic atrial fibrillation; echocardiography revealed a pericardial effusion. Aortic dissection and acute myocardial infarction were excluded by examination upon admission. His blood pressure subsequently dropped, indicating pericardial tamponade. Pericardiocentesis was performed, and 800 ml of bloody pericardial fluid were withdrawn, stabilizing his blood pressure. The blasts ratio was higher in the pericardial fluid than in the peripheral blood; bone marrow examination revealed no evidence of acute transformation, but the presence of numerous cells with chromosomal abnormalities in the pericardial sac cavity confirmed acute MDS transformation. The patient died on day 15 due to progressive multiorgan failure. The autopsy revealed a neoplastic lesion extending circumferentially throughout the epicardium.

Conclusions
When a patient with an acute onset history of hematogenous pericardial effusion is found to have a pericardial tamponade of cancerous origin, acute transformation of MDS should be considered in the differential diagnosis.
