Deciphering the Driving Mechanism and Regulatory Strategies of Antibiotic Resistance Genes Transmission in Lead-Contaminated Soil Microbial Communities by Multiple Remediation Methods

Pb-contaminated soil poses inherent risks for the spread of antibiotic resistance genes (ARGs). However, few reports have investigated the distribution of lead resistance genes (LRGs), particularly their role in ARGs dynamics during Pb-contaminated soil remediation. This study explored the mechanisms driving ARGs variation under different remediation strategies. The results indicated that an increase in the total abundance of ARGs after applying montmorillonite (Imvite), the composite remediation agents of MgO and Ca(H2PO4)2 (MgO-Ca(H2PO4)2), and the composite remediation agents of montmorillonite, MgO, and Ca(H2PO4)2 (Imvite-MgO-Ca(H2PO4)2). Bioelectrochemical systems (BES) effectively reduced ARGs abundance, and when combined with Imvite-MgO-Ca(H2PO4)2, lowered the risk of ARGs proliferation linked to antibiotic deactivation. Changes in Pb concentration and pH reshaped microbial communities, impacting both LRGs and ARGs. To reduce the risk of ARGs proliferation and transmission during, various control strategies, such as modifying Pb stress, adjusting pH, and manipulating microbial community structure, have been proposed. The study provided theoretical foundation and practical strategies for controlling ARGs dissemination during the remediation of heavy metal-contaminated soil.

A Channel-Sensing-Based Multipath Multihop Cooperative Transmission Mechanism for UE Aggregation in Asymmetric IoE Scenarios

With the continuous progress and development of technology, the Internet of Everything (IoE) is gradually becoming a research hotspot. More companies and research institutes are focusing on the connectivity and transmission between multiple devices in asymmetric networks, such as V2X, Industrial Internet of Things (IIoT), environmental monitoring, disaster management, agriculture, and so on. The number of devices and business volume of these applications have rapidly increased in recent years, which will lead to a large load of terminals and affect the transmission efficiency of IoE data transmission. To deal with this issue, it has been proposed to perform data transmission via multipath cooperative transmission with multihop transmission. This approach aims to improve transmission latency, energy consumption, reliability, and throughput. This paper designs a channel-sensing-based cooperative transmission mechanism (CSCTM) with hybrid automatic repeat request (HARQ) for user equipment (UE) aggregation mechanism in future asymmetric IoE scenarios, which ensures that IoE devices data can be transmitted quickly and reliably, and supports real-time data processing and analysis. The main contents of this proposed method include strategies of cooperative transmission and redundancy version (RV) determination, a joint combination of decoding process at the receiving side, and a design of transmission priority through ascending offset sort (AOS) algorithm based on channel sensing. In addition, multihop technology is designed for the multipath cooperative transmission strategy, which enables cooperative nodes (CN) to help UE to transmit data. As a result, it can be obtained that CSCTM provides significant advancements in latency and energy consumption for the whole system. It demonstrates improvements in enhanced coverage, improved reliability, and minimized latency.

An Anti-Collision Algorithm for Self-Organizing Vehicular Ad-Hoc Network Using Deep Learning

The rapid increase of the number of motor vehicles over the last several decades has driven a corresponding increase in the severity of traffic congestion, which has exhibited a considerable human impact. Intelligent anti-collision control via inter-vehicle communication technology can facilitate vehicles adhering to spacing speed standards and improve road utilization and traffic efficiency. In this paper, we apply a deep learning image estimation model based on joint attention mechanism. The network framework uses a deep estimation network Yolov5 and a location based VANET information fast transmission strategy to work together. This paper mainly considers vehicle distance measurement technology as a point of entry to study multi-sensor information fusion for vehicle collision prevention technology based on the self-organizing vehicular ad-hoc network (VANET). This paper also proposes a solution based on the strategy of one-way transmission of shared information and dynamic valuation of a cluster distance threshold with vehicle density. The proposed vehicle anti-collision control algorithm is designed to realize dynamic vehicle control via inter-vehicle communication. In this paper, the two-way coupling of traffic flow and network simulator is used to randomly generate vehicle nodes on the road, and the behavior of the anti-collision system is simulated. The experimental results show that the predetermined control goal is achieved, which demonstrates the effectiveness of the proposed algorithm.

Not all parents are the same: Diverse strategies of symbiont transmission in seaweeds.

Different marine seaweed species have been shown to harbour specific bacterial communities, however, the extent to which vertical symbiont transmission from parents to offspring contributes to host-specificity is unclear. Here we use fluorescence and electron microscopy as well as 16S rRNA gene-based community analysis to investigate symbiont transmission in members of the three major seaweed groups (green Chlorophyta, red Rhodophyta and brown Phaeophyceae). We found seaweeds employ diverse strategies to transfer symbionts to their progeny. For instance, the green Ulva australis does not appear to have the capacity for vertical transmission. In contrast, the brown Phyllospora comosa adopts a non-selective vertical transmission. The red Delisea pulchra demonstrates weak selectivity in symbiont transmission, while the brown Hormosira banksii exhibits a strongly selective symbiont transfer. Mucilage on the gametes appears to facilitate vertical transmission and transferred bacteria have predicted properties that could support early development of the seaweeds. Previous meta-analysis has indicated that vertical transmission is rare in aquatic compared to terrestrial environments, however, our results contribute to the growing evidence that this might not be the case and that instead vertical transmission with various degrees of symbiont selection occurs in the ecologically important group of seaweeds.

Adaptive shift strategy of a novel power-cycling variable transmission for construction vehicles

A new power-cycling variable transmission (PCVT) is proposed and applied to construction vehicles to improve transmission efficiency. To adapt to changes in external loads, construction vehicles need to shift gears continuously. However, the shift points obtained by traditional method cannot change with working conditions. This study aims to identify construction vehicles’ mass and gradient changes, and to develop a shift correction strategy. The double-forgetting factors least squares method is designed to identify slope gradient and load. A PCVT dynamic shift strategy is developed based on speed ratio adjustment characteristics. Next, a modified shift strategy under different loading mass and slope gradient conditions is proposed based on the construction vehicles’ mass change ratio, the gradient change ratio and balanced velocity. Simulation results show the proposed method can correct shift points, improve operation efficiency, avoid shift cycles and ensure a safer operation process.

Synchronization transmission of laser signals between networks with arbitrary topology within a finite time based on linear coupling strategy

Two complex networks are constituted by the single-ring erbium-doped fiber lasers (SREDFLs), and the scheme of synchronization transmission of laser signals is designed based on a linear coupling strategy. Furthermore, the signal transmission between the laser networks can be synchronously realized within a finite time. According to the numerical simulation, it is found that each error tends to zero after a short oscillation, implying that the synchronization transmission of the laser signal between corresponding nodes belonging to different networks is achieved in a foreseeable time. Meanwhile, all the coupling coefficients are also fixed to zero while the synchronization transmission between the laser networks is realized. Therefore, the simulation results prove that the control strategy of finite-time synchronization transmission between the laser networks based on a linear coupling technique is feasible and efficient.

Distinct Wolbachia localization patterns in oocytes of diverse host species reveal multiple strategies of maternal transmission.

A broad array of endosymbionts radiate through host populations via vertical transmission, yet much remains unknown concerning the cellular basis, diversity, and routes underlying this transmission strategy. Here, we address these issues, by examining the cellular distributions of Wolbachia strains that diverged up to 50 million years ago in the oocytes of 18 divergent Drosophila species. This analysis revealed 3 Wolbachia distribution patterns: (1) a tight clustering at the posterior pole plasm (the site of germline formation); (2) a concentration at the posterior pole plasm, but with a significant bacteria population distributed throughout the oocyte; and (3) a distribution throughout the oocyte, with none or very few located at the posterior pole plasm. Examination of this latter class indicates Wolbachia accesses the posterior pole plasm during the interval between late oogenesis and the blastoderm formation. We also find that 1 Wolbachia strain in this class concentrates in the posterior somatic follicle cells that encompass the pole plasm of the developing oocyte. In contrast, strains in which Wolbachia concentrate at the posterior pole plasm generally exhibit no or few Wolbachia in the follicle cells associated with the pole plasm. Taken together, these studies suggest that for some Drosophila species, Wolbachia invade the germline from neighboring somatic follicle cells. Phylogenomic analysis indicates that closely related Wolbachia strains tend to exhibit similar patterns of posterior localization, suggesting that specific localization strategies are a function of Wolbachia-associated factors. Previous studies revealed that endosymbionts rely on 1 of 2 distinct routes of vertical transmission: continuous maintenance in the germline (germline-to-germline) or a more circuitous route via the soma (germline-to-soma-to-germline). Here, we provide compelling evidence that Wolbachia strains infecting Drosophila species maintain the diverse arrays of cellular mechanisms necessary for both of these distinct transmission routes. This characteristic may account for its ability to infect and spread globally through a vast range of host insect species.

How to remember a place to forget? The semiotic design of deep geological nuclear repositories, from long-term communication to memory transmission

Abstract Drawing on the field of nuclear semiotics, this article critically discusses the classic problem of marking the location of a deep geological repository to communicate – in the distant future – its presence and potential threats to intruders. The article is divided into two parts. The first part reviews some site-marking solutions that have been proposed in the nearly 40 years of nuclear semiotics’ existence. These solutions are analyzed through the lens of semiotics of space and memory, highlighting different ideas about the purposes of site-marking, ranging from the idea of communicating a warning message to that of transmitting a memory. The second part addresses these strategies of memory transmission by examining some recent “speculative experiments” that use art to convey information about nuclear repositories to future generations. This part of the article examines artistic proposals submitted to a competition organized by ANDRA (the French Agency for Nuclear Waste).

Joint Optimization Method of Spectrum Resource for UAV Swarm Information Transmission

For the problems brought by malicious interference in the unmanned aerial vehicle (UAV) swarm network, we establish a cluster-based UAV swarm information transmission model. We mainly consider four aspects: cluster head selection, channel allocation, power allocation and UAV position. In order to improve the backhaul information rate of UAV swarm, we propose a joint optimization method of spectrum resource with the goal of maximizing the sum throughput of the cluster head UAV. We decompose the original mixed integer nonlinear programming (MINLP) problem into multiple sub-problems based on the block coordinate descent (BCD) technique, and then solve them based on convex optimization and successive convex approximation (SCA) technique. Simulation results show that the proposed method can obtain the spectrum resource optimization strategy of UAV swarm information transmission, reduce the impact of malicious interference, and effectively improve the backhaul information rate of UAV swarm.

Educare a identità multiple. Il ruolo cruciale delle madri migranti arabo-musulmane nel prevenire la radicalizzazione

Radicalization is a fairly recent issue of pedagogical reflection that can make a contribution in particular on the subjective, psychological and identity dimensions. The paper focuses on the analysis of the identity dimension, starting from a conceptualization of identity in a processual, dynamic, multiple perspective. It is then highlighted how the families with an immigrant background are in a position of risk but also of possibility within the dynamics of belonging/identity. Theoretical references on a culturally-informed concept of family and gender roles, together with data emerging from an ethnographic research conducted in Milan with immigrant mothers of Arab-Muslim origin, show how the latter can implement creative strategies of cultural transmission and education to multiple identities able to prevent radicalization. Supporting the mothers and their strategies is an important pedagogical, political and social task that requires adequate parenting support initiatives.
