Systemes repartis de grande taille: de l'anarchie a l'auto-structuration

L'auto-structuration est une propriete tres difficile a etablir dans les reseaux de grande taille lorsque les entites n'ont acces a aucune information globale concernant le reseau qu'elles composent. Dans ce contexte, il est crucial de permettre aux entites de se positionner les unes par rapport aux autres. Ceci peut-etre obtenu en definissant un systeme de coordonnees auquel les entites pourront se referer pour obtenir leur position. Un tel systeme fournit alors une brique de base pouvant etre utilisee pour l'auto-structuration. Dans cet article, nous presentons un tel systeme de coordonnees: VINCOS. Ce systeme, leger et completement decentralise, repose uniquement sur l'exploitation de donnees locales et la communication entre entites voisines. C'est une grande difference par rapport a la plupart des approches existantes qui reposent soit sur des referentiels predefinis, soit sur des systemes de positionnement auxiliaires. Des simulations montrent ensuite que cette approche est a la fois efficace et precise.
A Systematic Literature Review on Consequences of Social Media on Intimate Relationships

Technology advancement is imminent and has changed the way of communication nature. The high penetration of the Internet has contributed to the changes. People nowadays no longer need to meet each other to communicate physically. They can simply communicate with the usage of technology, such as social media. The Internet has helped with the emergence of social media. The usage of social media is beyond communicating with someone we know. The features such as creating a profile, sharing content, meeting strangers and more; has led it to be one of the most visited and consumed sites on the Internet. There are many effects of social media; effect on relationship is one of it. This paper adopts a systematic literature review to examine the effect of social media on intimate relationships. The findings reveal eight themes which are jealousy, online surveillance, sexting, self-disclosure, sexual function, relationship commitment, convenience, and infidelity.
Comparison of Ultra-Short Race Pace and High-Intensity Interval Training in Age Group Competitive Swimmers

The aim of this study was tο examine the acute responses to an Ultra-Short Race Pace Training (USRPT) and a High-Intensity Interval Training (HIIT), both oriented for the event of 100 m freestyle. Eighteen national-level swimmers (8 boys, 10 girls) aged 13.5 ± 0.1 years, with 8.0 ± 0.5 years of experience participated in the study. All participants completed a USRPT and a HIIT protocol consisting of 2 × 10 × 25 m (USRPT1 & USRPT2) and 5 × 50 m. Significantly higher swimming velocity (SV) were achieved in USRPT compared to HIIT (p < 0.001), while significantly lower distance per stroke (DPS) and stroke index (SI) were obtained (p = 0.007 and p < 0.001). Also, significantly lower blood lactate and glucose (BL & BG) concentrations were found after USRPT (p ≤ 0.001 and p = 0.037). Heart rate (HR) and rate of perceived exertion (RPE) were significantly lower after USRPT than HIIT (p < 0.001 and p = 0.015). According to the results, an USRPT swimming set consisting of 20 × 25 m at a 100 m pace seems to induce more specific responses in kinematic characteristics, biomarkers, HR and RPE compared to a 5 × 50 m HIIT set.
Research on the Development of a Way to Modify Asphalt Mixtures with PET Recyclates

Due to the growing need to recycle plastics, new possibilities for their reuse are intensively sought. In the Asian market, waste polymers are increasingly used to modify road bitumen. This solution is beneficial in many aspects, especially in economic and ecological terms. In this work, recycled poly(ethylene terephthalate) (RPET), obtained from storage points located in Lesser Poland, was subjected to material recycling, and its properties were examined using three analyses: differential scanning calorimetry (DSC), thermogravimetric analysis (TG), and Fourier transform infrared spectroscopy (FTIR). The most important point of this research was the selection of conditions for obtaining modified asphalt mixtures through the addition of RPET. Subsequently, the effect of the polymer on the properties of road bitumens was assessed on the basis of penetration tests, softening point, elastic recovery, and structure. In the last stage of our research work, asphalt mixtures with the addition of modified waste PET (PMA) containing mineral filler in the form of basalt dust were obtained. The properties of the obtained mineral–polymer–asphalt mixtures were compared in terms of frost resistance, structure, and abrasion resistance with the properties of mineral–asphalt mixtures that were taken from damaged road surfaces in four points in the city of Tarnów (Lesser Poland) in the winter of 2022. It has been shown that the modification of road bitumen with the use of recyclate and mineral filler has a significant impact on its performance properties.
Correlation between KRAS Mutation and CTLA-4 mRNA Expression in Circulating Tumour Cells: Clinical Implications in Colorectal Cancer

Combination strategies of KRAS inhibition with immunotherapy in treating advanced or recurrent colorectal carcinoma (CRC) may need to be assessed in circulating tumour cells (CTCs) to achieve better clinical outcomes. This study aimed to investigate the genomic variations of KRAS in CTCs and matched CRC tissues and compared mRNA expression of KRAS and CTLA-4 between wild-type and KRAS-mutated CTCs and CRC tissues. Clinicopathological correlations were also compared. Six known mutations of KRAS were identified at both codon 12 and codon 13 (c.35G>T/G12V, c.35G>A7/G12D, c.35G>C/G12A, c.34G>A/G12S, c.38G>C/G13A, and c.38G>A/G13D). Three CTC samples harboured the identified mutations (16.7%; 3/18), while fifteen matched primary tumour tissues (65.2%, 15/23) showed the mutations. CTCs harbouring the KRAS variant were different from matched CRC tissue. All the mutations were heterozygous. Though insignificant, CTLA-4 mRNA expression was higher in patients carrying KRAS mutations. Patients harbouring KRAS mutations in CTCs were more likely to have poorly differentiated tumours (p = 0.039) and with lymph node metastasis (p = 0.027) and perineural invasion (p = 0.014). KRAS mutations in CTCs were also significantly correlated with overall pathological stages (p = 0.027). These findings imply the genetic basis of KRAS with immunotherapeutic target molecules based on a real-time platform. This study also suggests the highly heterogeneous nature of cancer cells, which may facilitate the assessment of clonal dynamics across a single patient’s disease.
Adaptive UDE-Based Distributed Consensus Control for Multiple Euler-Lagrangian Systems with Communication Delays

This paper focuses on the distributed consensus tracking problem for multiple Euler-Lagrangian(EL) systems with communication delays. An adaptive uncertainty and disturbance estimator (UDE)-based control method is proposed, which can not only eliminate the disturbances of the system, but also achieve consensus tracking of multiple EL systems with good adaptability to the communication delay problem of the system. Moreover, a unified analysis framework of closed-loop control system is established by Lyapunov-like analysis. The proposed algorithm is simple in structure and has good robustness for dealing with external disturbances. Finally, the accuracy and effectiveness of the proposed method are verified by simulation experiments.
Genome-Wide Identification of BrCAX Genes and Functional Analysis of BrCAX1 Involved in Ca2+ Transport and Ca2+ Deficiency-Induced Tip-Burn in Chinese Cabbage (Brassica rapa L. ssp. pekinensis)

Calcium (Ca2+) plays essential roles in plant growth and development. Ca2+ deficiency causes a physiological disorder of tip-burn in Brassiceae crops and is involved in the regulation of cellular Ca2+ homeostasis. Although the functions of Ca2+/H+ exchanger antiporters (CAXs) in mediating transmembrane transport of Ca2+ have been extensively characterized in multiple plant species, the potential roles of BrCAX genes remain unclear in Chinese cabbage. In this study, eight genes of the BrCAX family were genome-widely identified in Chinese cabbage. These BrCAX proteins contained conserved Na_Ca_ex domain and belonged to five members of the CAX family. Molecular evolutionary analysis and sequence alignment revealed the evolutionary conservation of BrCAX family genes. Expression profiling demonstrated that eight BrCAX genes exhibited differential expression in different tissues and under heat stress. Furthermore, Ca2+ deficiency treatment induced the typical symptoms of tip-burn in Chinese cabbage seedlings and a significant decrease in total Ca2+ content in both roots and leaves. The expression changes in BrCAX genes were related to the response to Ca2+ deficiency-induced tip-burn of Chinese cabbage. Specially, BrCAX1-1 and BrCAX1-2 genes were highly expressed gene members of the BrCAX family in the leaves and were significantly differentially expressed under Ca2+ deficiency stress. Moreover, overexpression of BrCAX1-1 and BrCAX1-2 genes in yeast and Chinese cabbage cotyledons exhibited a higher Ca2+ tolerance, indicating the Ca2+ transport capacity of BrCAX1-1 and BrCAX1-2. In addition, suppression expression of BrCAX1-1 and BrCAX1-2 genes reduced cytosolic Ca2+ levels in the root tips of Chinese cabbage. These results provide references for functional studies of BrCAX genes and to investigate the regulatory mechanisms underlying Ca2+ deficiency disorder in Brassiceae vegetables.
Loopholes in Environmental Laws Allow for Incomplete Remediation

At least 103 children in Toms River, Dover Township, New Jersey had been diagnosed with cancer in what is believed to be the nation’s largest child cancer cluster. In 1995, a state study found that incidence of cancer among children in Toms River was higher than any other part of the state. In Dover Township, it was reported that 90 children were found to have various types of cancer between 1979 and 1995. Since the original cases, 28 more children there have been found to have cancer, the families said. Over a period of decades, chemical plants, including ones owned by Ciba-Geigy released industrial pollutants into the Toms River. Industrial pollutants leached into the township’s groundwater supply. The pollutants included chemicals used in the manufacture of epoxies, resins, and dyestuffs. In 1983, the United States Environmental Protection Agency (USEPA) listed the site on the Superfund National Priorities List that includes the country’s most polluted sites. Remediation is now underway at the site and is expected to be completed by the end of 2010. The remediation efforts do not include removal of all the drums. The drums should not be left there in order to keep costs down. The problem here is that loopholes in the law regarding how remediation is carried out in New Jersey allow for too much agency discretion. The compromises that are made between state officials and businesses to lower remediation costs should never raise the citizen’s health risk. This compromise means that drums will be left on-site. The drums will leak again and it is just a matter of time. Leaving the drums there is a danger, an unnecessary risk that leaves children at risk for further injuries. In short, this case study is an example of the large barriers preventing sustainability at the regional level.
A Crocodile-Like Pneumatic Soft Crawling Robot With Three-Dimensional Deformation Actuators

Pneumatic soft crawling robots (PSCRs) have excellent application prospects in disaster relief and resource exploration due to their adaptability to complex environments. However, the crawling ability of PSCRs, including speed, load capacity, etc., is difficult to meet the requirements of these applications. To this end, a crocodile-like PSCR with three-dimensional deformation actuators is designed. First, based on the analysis of the crocodile structure, four leg actuators and a body actuator are designed, respectively, and their fabrication processes are described in detail. Meanwhile, a complete structure of the crocodile-like PSCR including connectors and air circuits is assembled. Then, the geometric and finite element models of leg actuators are established to analyze bending characteristics. On this basis, according to the relationship among the actuators, different gaits are designed to achieve moving forward, turning, and other movements. Finally, experimental results verify that leg actuators are fabricated accurately and the crocodile-like PSCR has satisfactory crawling ability.
Learning-Based Model Predictive Control for Vehicles with Modeling Bias

The dynamic uncertainty system has modeling bias, which has led to an increasing interest in learning-based model-driven control technology. In order to integrate the advantages of self-exploration of reinforcement learning (RL) and high robustness of model predictive control (MPC), we propose a learning-based model predictive control (LMPC) method. This algorithm is a method that can find the optimal control strategy under the guidance of simplified model and fuzzy cost function. The results show that taking vehicle motion control as an example. By adjusting the variable horizon, the vehicle model built can quickly and effectively achieve the control objectives. Compared with DDQN, LMPC reduces the disorder enumeration of RL, accelerates the optimization process of the control system to the target, and makes the exploration process more stable. Compared with MPC, it solves the problem that the control accuracy of the control system is not high and the model and parameters cannot be adjusted adaptively under the simplified modeling.
Etude des instabilités volumiques en extrusion de polystyrène et polypropylène

Nous etudions experimentalement les instabilites helicoidales et chaotiques, des defauts d'extrusion de polymeres fondus, sur deux polystyrenes et un polypropylene a l'aide de deux dispositifs experimentaux: un rheometre capillaire et une extrudeuse monovis, munie d'une filiere plate a parois transparentes, permettant d'effectuer des mesures de birefringence d'ecoulement et de velocimetrie laser-Doppler. Dans ce dernier cas, on dispose d'une geometrie d'ecoulement constituee d'un reservoir, suivi d'une contraction et d'un canal d'ecoulement. En rheometrie capillaire, nous avons etudie l'influence des conditions d'ecoulement (diametre, longueur, angle d'entree de la filiere, temperature.) sur le declenchement de l'instabilite helicoidale. Les essais de birefringence ont permis l'observation d'oscillations transverses d'isochromes dans le reservoir: lors de ce regime instable, l'ecoulement principal a lieu de facon non symetrique dans le canal. On montre egalement que l'utilisation de "convergent doux" permet de repousser la destabilisation de l'ecoulement d'entree a des debits sept fois plus importants que dans le cas d'une contraction brusque. On s'attache a mesurer, sur l'axe de symetrie du reservoir, des premieres differences de contraintes normales et de taux de deformation dans les conditions critiques propres a l'initiation du defaut, par birefringence d'ecoulement et velocimetrie laser-Doppler, respectivement. Des calculs viscoelastiques de l'ecoulement par elements finis ont egalement permis l'estimation de la repartition des contraintes elongationnelles autour de la contraction, dans les conditions critiques d'apparition de l'instabilite.
Metamaterials in Medicine: A New Era for Future Orthopedics

In 1898 J.C. Bose showed the possibility of existence of artificial material by conducting microwave experiment on twisted structure. Later, in 1968, Russian physicist Victor Veselago considered the electromagnetic properties of a hypothetical materialwhose electric permittivity and magnetic permeability were both negative [2]. Such a material, as Veselago mentioned, did not exist in nature. Smith et al. had recognized gradient refractive index medium to bend electromagnetic waves. Metamaterial opened up a new exciting world for the scholars.
Surveys of oil spill incidents affecting mangrove habitat in Australia: A preliminary assessment of incidents, impacts on mangroves, and recovery of deforested areas

Over the past three decades, nine notable oil spills affected mangrove habitat in Australia. Six were the result of shipping incidents, and three others were land-based incidents. There were two incidents in the 1970s, three in the 1980s, and four in the 1990s. Types of oil released changed from crude oils in the 1970s to fuel and diesel oils in the 1990s. The total volume of oil released into Australian waters in mangrove-related incidents since 1970 was around 5,000 tonnes. Dispersants were used in the four major incidents involving shipping. Hydrocarbon in sediments generally decreased rapidly after spillage, leaving unrecognisable trace residual fractions in most locations after several years. At least 220 ha of mangroves were oiled in Australia since 1970, and around 13 ha were killed. The extent of oiling depended largely on the amount of oil released. The area of deforestation however, depended on the type of oil with the greatest areas killed by crude oils and diesel, and lesser damage caused by fuel oils. Recovery of deforested sites depended chiefly on site exposure. Sites of greatest exposure experienced both rapid and slow recovery, and sometimes rapid decline. In exposed locations, sediment flushing appeared important in stimulating recovery, while greater exposure also allowed premature destruction of growing plants by strong seas and storms. Based on estimates of total above-ground biomass, mean rates of recovery matched those observed in Panama, and full biomass recovery of areas deforested by oil spills might take around 36 years on average, with 50 per cent recovery after 20 years.
Disseminated Nontuberculous Mycobacterial Infection in a Tertiary Referral Hospital in South Korea: A Retrospective Observational Study

Purpose Disseminated nontuberculous mycobacterial (D-NTM) disease occurs primarily in immunocompromised hosts. However, these cases have rarely been reported in South Korea. This study aimed to describe the clinical manifestations, disease course, and underlying immune deficiencies of patients with D-NTM disease. Materials and Methods We retrospectively reviewed the cases of D-NTM disease from January 2005 to December 2019 at a tertiary referral hospital in South Korea. D-NTM disease was defined as a bloodstream infection or infection of two or more non-contiguous body organs with species identification. Results Of the 53342 mycobacterial samples from 23338 patients, extrapulmonary NTM was detected in 104 patients, and 3 (2.9%) were diagnosed with D-NTM disease. Mycobacterium avium was isolated from two patients, while M. abscessus subspecies abscessus was identified in one. The patients were aged between 18 and 25 years, and two patients were male. All patients were immunocompromised – one received lung transplantation, one was diagnosed with anhidrotic ectodermal dysplasia with T-cell immune deficiency, and one had monocytopenia and mycobacterial infection syndrome associated with GATA2 mutations. All patients underwent a standard macrolide-based regimen for >5 months, and their sputum tested negative. However, one patient died of bacterial sepsis, while the other two survived. Conclusion D-NTM disease is rare in a tertiary referral center in South Korea. They occur primarily in immunocompromised patients at a relatively young age. Careful investigation of the underlying immune status is required when treating patients with D-NTM disease.
Examining the Mediating Role of School Culture in the Relationship between Heads’ Instructional Leadership and Students’ Engagement at Secondary Level in Punjab, Pakistan

Present study aims to investigate the mediating role of school culture (SC) in the relationship between heads’ instructional leadership (IL) and students’ engagement (SE) at secondary school level. The target population was comprised of all secondary school teachers of district Punjab. Multistage sampling techniques were used to select the sample. The sample was consisted of 1016 secondary school teachers. Questionnaire was used to collect data. Structural Equation Modeling (SEM) technique was used to analyze the mediating effect. Results revealed that total effect of IL on SE is statistically significant (β=0.655, t= 27.572, p= 0.000), while the direct effect of IL on SE becomes statistically in significant (β= 0.109, t=1.480, p=0.139). However the indirect effect of IL on SE through the mediation of SC is statistically significant (β=0.546, t= 8.662, p= 0.000). These findings show that school culture is a statistically significant mediator for the relationship between heads’ instructional leadership and students’ engagement.
Holistic attack methods against power systems using the IEC 60870-5-104 protocol

IEC 60870-5-104 is a widely used protocol for telecontrol in European power systems. However, security was not a design goal when it was originally published: This protocol lacks built-in security features such as encryption, integrity protection, or authentication. In this paper, we describe novel types of attacks against the protocol in a holistic way. Therefore, we also enumerate the possible entry points of the threat actors and demonstrate a new technique, where the malicious actor can precisely target the attack. These methods are demonstrated both on simulated environment and actual devices and compared with already published methods.
Modeling and Operating Point Analysis for Aquatic Translational Motion of a Cross-Medium Vehicle

Modeling of cross-medium vehicles with complex shapes still requires a thorough investigation. This paper proposes a multi-method combination modeling approach to tackle such a problem. First-principle model is derived to determinate a model structure. Experiments are then set up to estimate parameters related to its rigid-body model and propulsion system. Computational fluid dynamics (CFD) is performed to calculate and identify coefficients related to surrounding fluid. Base on the model obtained, we systematically investigate the possible steady motion of the cross-medium vehicle and analyze their related performance. Results are instrumental for designing controllers for the vehicle to perform autonoumous missions.
Privacy-Preserving Leaderless and Leader-Following Consensus Based on Event-Triggered Mechanism

This paper mainly studies the privacy-preserving consensus problems of first-order discrete multi-agent systems via event-triggered control. In order to realize ciphertext interaction to protect the privacy of each agent in the communication network, while reducing the cost of cryptographic calculation and additional communication consumption, a confidential interaction protocol under the event-triggered mechanism (ETM) is constructed, a ETM compatible with the confidential interaction protocol is proposed, whose implementation only relies on the information that agents can obtain through the proposed confidential interaction protocol. In addition, the communication rules between agents using the confidentiality interaction protocol under the event trigger mechanism is clearly stated. The feasibility of ETMs are proved theoretically and the effectiveness of the theoretical results are demonstrated by numerical simulations.
