Pets becoming established in the wild: free–living Vietnamese potbellied pigs in Spain
Authors:   REC, CSIC–UCLM–JCCM, Ciudad Real, Spain, Delibes–Mateos M. , Delibes A. ,   Junta de Castilla y León, Valladolid, Spain
Published: December 2020

Vietnamese potbellied (VPB) pigs (Sus scrofa) are a common pet in North America and Europe, but their recent decrease in popularity has increased their abandonment. Our main aim was to identify potential cases of free–living VPB pigs in Spain through an in–depth Google search. We identified 42 cases of free–living VPB pigs distributed throughout the country. The number of free–living VPB pigs reported increased by year but the species abundance still seems to be low. Signs of VPB pig reproduction and possible hybrids between VPB pigs and wild boar or feral pigs have been also reported. Free–living VPB pigs could erode the gene pool of the Spanish wild boar population and exacerbate the damage (e.g. crop damage or spread of diseases) already caused by wild board. Urgent evaluation and adequate management of wild VPB pig sightings is needed to prevent their establishment in natural habitats.

Authors: Widodo Puwanto
Published: December 2020

Research on dynamic capital structure basically wants to know the existence of targeted leverage as hypothesized by Trade-Off Theory and Speed off Adjustment (SOA). Later developments, the magnitude of the speed of adjustment can be used as a determinant of capital structure theory used by the company. Another problem in dynamic capital structure research is the use of analytical tools that can produce biased and inconsistent predictors. To overcome this, this study uses dynamic panel data with the General Method of Moment (GMM) approach. Samples were taken from non-financial companies listed on the Indonesia Stock Exchange in the 2009-2015 period. The results of the inference show the existence of Dynamic Trade Off Theory and the variables of company characteristics and macroeconomic significantly influence the dynamic capital structure. In addition, it is known that there is an influence of company size and growth Opportunity on the speed of adjustment. Another finding is that he knows that managing profitability follows and Pecking Order Theory.Keywords : capital structure, static model, dynamic model

Published: December 2020

Grain mold, considered the most important disease of sorghum, is associated with several fungal genera. The disease reduces both yield and quality. In this study, over 300 sorghum seed samples collected from Texas, Florida, and Georgia were evaluated for grain mold severity, seed weight, germination rate, and seed fungal community. Grain mold severity of the seed samples, except for those collected from Cameron, Texas, were rated 3 or higher, indicating that these sorghum lines were moderately susceptible under naturally-infected field conditions during the 2016 and 2017 growing seasons. Seed weight across surveyed locations ranged from 1.1 g to 4.0g for samples collected in Texas during the same period. Percent germination rates for samples collected in Texas ranged from 59.6% to 86.7%. Sorghum samples collected from Florida and Georgia exhibited moderately susceptible response to grain mold infection. Mean seed weight was 1.9 g for samples collected from Florida, while in Georgia, mean seed weight was 2.3 g. Germination rate was low for samples collected from Florida and Georgia. Mycological analysis of sorghum seed samples collected from farmers’ fields in Central and South Texas during the 2016 and 2017 growing seasons showed Alternaria species as the most frequently isolated fungal genus, accounting for 40% and 42 % in 2016 and 2017, followed by Fusarium incarnatum, F. acuminatum, F. equiseti, & F. semitectum Complex. In Florida and Georgia, Fusarium incarnatum, F. acuminatum, F. equiseti, & F. semitectum Complex was the most frequently recovered fungal species, accounting for 77% and 72% of the total. genera/species isolated from seed samples. Other fungal species, including Curvularia lunata, Bipolaris sp., Colletotrichum sublineola, F. verticillioides, Penicillium sp., Aspergillus flavus, F. thapsinum, F. oxysporum, F. sporotrichioides, F. graminearum, F. proliferatum, and Aspergillus niger were also isolated from sorghum seeds in various frequencies. In conclusion, the presence of large number of fungal genera associated with grain deterioration and their effect on other traits, makes management of this disease complex challenging. To identify grain mold resistant sources in a region, using the most dominant species in that region to screen the sorghum germplasm is recommended.

Euphorbia davidii Subils (=Euphorbia dentata Michx) та Euphorbia maculata L. – адвентивні види рослин північноамериканського походження, що вперше було виявлені в Україні на при кінці ХХ століття і відомі з небагатьох місцезнаходжень. В останні роки нами було знайдено декілька нових місцезнаходжень цих рослин на Півдні України. Euphorbia davidii виявлено в 2 локалітетах: м. Олешки Херсонської області та в околицях с. Прогресівка Березанського району Миколаївської області. Для Миколаївської області E. davidii наводиться нами вперше. Усі раніше відомі в Україні локалітети E. davidii приурочені до залізниць та портів, тобто вирогідних первинних осередків інвазії. Знайдено нами нові локалітети є досить віддаленими від первинних осередків інвазії, що свідчить про поширення E. davidii територією України в межах вторинного ареалу. Виявлені в останні роки нові місцезнаходження E. davidii – на залізниці в різних частинах України, та поява виду за межами первинних осередків інвазії вказує на тенденцію до натуралізації його в Україні. Euphorbia maculata знайдено в 7 локалітетах в Херсонській (м. Херсон та околиці, м. Скадовськ, околиці м. Олешки) та Дніпропетровській (м. Кривий Ріг) областях. Для Херсонської області E. maculata наводиться нами вперше. Значна кількість нових місцезнаходжень, в тому числі за межами первинних осередків розселення, висока чисельність особин в більшості з них, свідчить про успішну натуралізацію рослини. Принаймні в Херсонській області E. maculatа можна вважати епекофітом. Крім того у 2019 році E. maculata було знайдено нами в Азербайджані (м. Баку), де він є дуже рідкісним. З високою ймовірністю можна прогнозувати подальше поширення E. davidii та E. maculata в Україні.

Authors: Hoang Thien Dinh , Kovács Balázs , Madarász Tamás , Czinkota Imre
Published: December 2020

One of the most significant current discussions in fluid transport industry is how to prolong the service life of a metallic pipeline system under severe physical and chemical conditions. Electrochemical corrosion is a persistent problem, causing material degradation and sometimes resulting in serious consequences. Here more than 150 three-point bending tests were done on 82 corroded carbon steel pipes to examine their remaining strength. The current work proposes an artificial protocol to accelerate the electrochemical corrosion of ferrous tubes in a controllable system and analyzed correlations between removed iron mass, the depth of corroded sites, and the deterioration in the mechanical properties of the sample pipes. Based on these correlations, a rough estimate for the retirement life of pipelines is put forward as a referable option.

Published: December 2020

On the basis of the one-dimensional theory of calculating the operation of steam turbine stages the method for determining the idle mode, the initial data for which are the geometric characteristics of the blade rows is proposed. Formulas have been obtained that make it possible to calculate the efficiency in the proximity of Rotor Blades (RB) at operating modes from nominal to the idle mode, depending on the flow rate of the stage and taking into account the use of kinetic energy with the runaway velocity and losses arising at off-design angles of flow on the Rotor Blade (RB). The results of possible computational studies and their comparison for an incompressible working fluid with the results of experimental studies showed the good possibilities of the proposed method for determining the idle mode in a wide range of the characteristics of stages.

Loanwords from unattested Nordic source forms in Saami
Authors: Aikio Ante
Published: December 2020

Among the numerous loanwords Saami has adopted from Proto-Norse there are also cases where the loan original has not been retained in modern or historically attested Nordic languages. Such etymologies can nevertheless be established on the basis of surviving cognate forms in other Germanic languages. Seven previously proposed etymologies of this kind are scrutinized, including those for North Saami duodji ‘handicraft’ and ráidalas ‘ladder’. Twelve new etymologies of the same type are argued for, among them explanations for the origin of North Saami ámadadju ‘face’, iktit ‘reveal, disclose’, and ivdni ‘color’.

Authors: ZEREN Fatma , YILANCI Veli
Published: December 2020

COVID-19 is first detected on 12 March 2020 in Turkey, and since that day more than 100 thousand people are infected. In this study, we aim to determine risky provinces in terms of COVID-19 outbreak and also explore the spatial dynamics of the outbreak in Turkey using province-level data. To analyze spatial patterns of COVID-19, we employ spatial dependence statistics Moran-I. Also, we employ Local Indicator Spatial Association-LISA to detect the hot-spots and cold-spots. Moran-I coefficient found as low and statistically significant that shows spatial interaction is not strong in the context of the whole country. Also using LISA, we found Düzce, Kocaeli, Ordu, Tekirdağ, and Trabzon as hot-spots for data period, which indicates these cities can be classified as risky in terms of COVID-19 outbreak. There are more spatial interaction with their neighbours cities. In terms of the COVID-19 variable, in hot-spot provinces and neighboring provinces of these provinces, measures should be intensified, and control should be increased.

Freud e a Biologia: do projeto de uma psicologia científica para a teoria psicanalítica
Authors: Souza Adriano Junio Moreira de
Published: December 2020

Objetivo: Traçar um paralelo entre o modelo neurológico desenvolvido por Freud em 1895 e seus constructos metapsicológicos de 1900 e 1923. Métodos: Trata-se de uma revisão de literatura fundamentada nos seguintes escritos de Freud: “Projeto para uma psicologia científica” (1895), “A interpretação dos sonhos” (1900) e “O eu e o id” (1923). Outras obras e outros autores foram incluídos. Revisão de literatura: Possibilitou identificar que para dar sequência à sua teoria da mente Freud migrou do modelo neurológico para uma perspectiva virtual da atividade psíquica. Nesse processo, Freud passou por três modelos - o modelo neurológico (1895), o modelo topográfico (1900) e o modelo estrutural (1923). Conclusão: Conclui-se que as ideias e conceitos desenvolvidos no modelo neurológico de 1895 estão presentes ao longo da evolução dos constructos teóricos de Freud.

Published: December 2020

A inovação é reconhecida como um movimento complexo e construído a partir de diversas dinâmicas. Precisa aplicar a criatividade e construir novos produtos, a inovação requer também o entendimento de outros tantos fatores socioeconômicos, culturais e mercadológicos envolvendo a formação técnica-científica. Assim, o objetivo desse artigo é caracterizar a inovação numa visão teórico-prática, triangulado com as questões da Propriedade Intelectual e da relação Universidade-Empresa. A partir da abordagem qualitativa de pesquisa, a metodologia adotada foi descritiva exploratória, com uso de dados secundários com as principais referências nas áreas citadas e artigos científicos capturados na plataforma Scorpus. Somado a isso, foi adicionado dados atualizados, de modo a entrelaçar a teoria à prática.  Ao final, percebeu-se evidências do quão a inovação vem ratificando seu papel socioeconômico na sociedade contemporânea. Como resultado, verifica-se o significativo papel da relação governo-universidade-mercado – Triple Hélix – como fonte de estímulo à inovação, apelo à criatividade e uma atenção específica à Propriedade Intelectual.

Published: December 2020

Objective: The aim of this study was to evaluate the diagnostic capability of dentists in the identification of suggestive images of calcified carotid artery atheroma (CCAA) on panoramic radiographs (PRs) before and after using a problem-based learning method (PBL). Methodology: Five dentists (no specialists in oral and maxillofacial radiology) analyzed 102 digital PRs divided into: PRs with suggestive images of CCAA (n=51) and without suggestive images of CCAA (n=51). After the first analysis, the examiners attended an activity on soft tissue calcifications using the PBL method. Afterwards, they analyzed the 102 PRs again. The results of the analysis were calculated using the Cohen's Kappa Test and the Receptor Operational Characteristic Curves (ROC). Results and Discussion: Regarding examiners’ performance before and after the activity, the intra-examiner test showed reasonable Kappa coefficients (0-0.40). For inter-examiner agreement after the activity, the Kappa coefficient was almost perfect (> 0.80). When comparing examiners’ performance after the activity with a template performed by an experienced radiologist, the Kappa Coefficient was > 0.80 with significant agreement (p<0.05). Conclusion: The precision and the probability of correctly detecting suggestive images of CCAA on PRs increased when the examiners participated in the active pedagogical method. The continuing education of the dentist and how it can make a difference in the systemic health of patients should be considered.
Inoculação de microrganismos e adição de resíduos para recuperação de área degradada no Cerrado, efeitos após seis anos de intervenção

Published: December 2020

Áreas degradadas decorrem da ação antrópica, como as adjacentes às usinas hidrelétricas (UHE), onde o solo é removido para uso na construção da barragem. Sem a camada fértil, o subsolo exposto não contribui à regeneração natural. Em decorrência da intensa degradação, novas tecnologias são requeridas para seu recobrimento vegetal e recuperação de suas funções ecossistêmicas. Nesta busca, procedeu-se a inoculação (solo-inóculo) de microrganismo e a adição de resíduos. Transcorridos seis anos, este estudo teve por objetivos avaliar os atributos químicos e microbiológicos do solo, bem como o crescimento espontâneo de gramíneas nativas, neste trabalho consideradas indicadoras. O trabalho foi realizado numa área degradada para a construção da UHE, em Selvíria-MS, na fazenda da UNESP-Faculdade de Engenharia, Campus de Ilha Solteira, cuja vegetação original era o Cerrado. O delineamento experimental foi blocos casualizados, em esquema fatorial 2 x 4, ou seja, 4 tratamentos de resíduos nas covas (macrófitas-MC, cinza da queima do bagaço de cana-de açúcar-CZ, MC+CZ e controle sem resíduos) e 2 tratamentos de solo-inóculo (com e sem), com 4 repetições (blocos) e 5 covas por repetição. O solo-inóculo, fonte de microrganismos, incluindo esporos de fungos micorrízicos arbusculares (FMA), foi coletado em Cerrado preservado. Incrementos nos teores de P, K, Ca, SB e V%, com redução para Al e maior esporulação de FMA foram proporcionados pela adição de solo-inóculo, mas não pelos resíduos. Após seis anos da sua implantação constataram-se pequenas alterações, indicando que as contribuições dos resíduos já foram esgotadas, ou que a quantidade aplicada foi insuficiente devido a intensa degradação existente.

Published: December 2020

The Brazilian Institute of Environment and Renewable Natural Resources (IBAMA) determines a regulatory set of instructions for fisheries agreements. These rules control fishing activity in Brazilian basins during closed fishing seasons. However, many fishermen violate the agreements, as seen in the river basin Uba, in the municipality of Moju-Pará. When fishermen breach IBAMA’s stated regulations, the municipality is urged to act on the case, but with little knowledge of critical areas which suffer from overfishing. This makes the logistics of solving these issues difficult and often problematic. This work strives to serve as an aid to environmental agencies in their endeavor to inspect and regulate the issue of overfishing in critical areas, such as the Úba river basin in the municipality of Moju-Para. Our methods include a literature review of research concerning the issue, identifying critical points, as well as preparing maps and proposals for the site of environmental monitoring activities in the city. From within the critical points, we identified the hot spots. We observed five distinct vegetation types located roughly 10 kilometers along the river, and the corresponding agricultural anthropic areas to 49% of the entire study area’s territory. It is noted that the areas of greatest concentrations of overfished territories are lined with countryside, forest and dense vegetation. Thus, environmental inspections should take place in areas near the communities and the Úba river and especially in the area beyond the Levi resort, where the hot spot was identified, while always considering the logistics for hard to reach areas.

The ‘Tectonic Sensibility’ in Architecture: From the Pre-Human to the Post-Human
Authors: Hale Jonathan
Published: December 2020

This paper argues for a new definition and a broader application of tectonic theory in architecture. It extends the traditional understanding of tectonics as a bodily feeling for the physical materiality of constructional elements, in order to form the basis of a more generalized notion of a bodily sensibility towards the ‘the way things are’. The discussion is informed by an evolutionary perspective on the relationship between technology and human embodiment, suggesting links between the ‘pre-human’ and the ‘post-human’. It offers a reassessment of an often overlooked but pivotal insight evident in the work of both André Leroi-Gourhan and Maurice Merleau-Ponty, that the human and the technological are mutually co-constitutive. It explores this notion in the light of recent research in archaeology, evolutionary, psychology, philosophy and neuroscience.

Authors: HUSSEIN Bikhtiyar , YESILTAS Mehmet
Published: December 2020

The study investigated direct and indirect impact of emotional intelligence on employee counterproductive work behavior and organizational commitment through transformational leadership. On the basis of theoretical and empirical studies, one exogenous variable (emotional intelligence) and three endogenous variables i. e transformational leadership, counterproductive work behavior, and organizational commitment were analyzed through structural equation modeling with the aid of AMOS V24. The participants were 302 administrative staff of private universities in Kurdistan region of Iraq. This study found emotional intelligence to significantly reduce counterproductive work behavior, while it was also found to significantly enhance employee commitment to their organization and transformational leadership. Moreover, transformational leadership was found to have a significant effect of reducing counterproductive work behavior among the staff, while it encourages their commitment to the university. In addition, transformational leadership was found to have a positive partial mediation in the relationship between emotional intelligence and counterproductive work behavior on one hand, and the relationship between emotional intelligence and organizational commitment on the other hand. Finally, the theoretical and practical implications of the study were addressed.

Health education is a key element in health promotion and requires strong planning based on theories of medical behavior. The study was conducted over a period of three years, January 2015 - December 2017, by means of an 11 items questionnaire anonymous applied to dentists or medical staff. Seven questions were multiple choice to allow a broader discussion of the results and the rest were one answer. The time of dental practitioners is limited, so their view of the duration of a possible dental health program is essential. Hours per week volunteered, vary from one doctor to another: from 1-3 hours or less to 3-5 hours or as needed. Assessing the willingness to engage (82%) and the time allocated to the dentists surveyed (44% between 1 and 3 hours per week and 51% over 3 hours per week), we can say that we have human resources for implementing an oral health project. The workforce in the field of oral health would like to be involved in such a program and believes that it could benefit from such a program and the construction of appropriate working mechanisms, especially designed for different regions, rural areas and diverse demographic of social categories.

The incorporation of functional building blocks to construct functionalized and highly porous covalent triazine frameworks (CTFs) is essential to the emerging adsorptive-involved field. Herein, a series of amide functionalized CTFs (CTF-PO71) have been synthesized using a bottom-up strategy in which pigment PO71 with an amide group is employed as a monomer under ionothermal conditions with ZnCl2 as the solvent and catalyst. The pore structure can be controlled by the amount of ZnCl2 to monomer ratio. Benefitting from the highly porous structure and amide functionalities, CTF-PO71, as a sulfur cathode host, simultaneously demonstrates physical confinement and chemical anchoring of sulfur species, thus leading to superior capacity, cycling stability, and rate capability in comparison to unfunctionalized CTF. Meanwhile, as an adsorbent of organic dye molecules, CTF-PO71 was demonstrated to exhibit strong chemical interactions with dye molecules, facilitating adsorption kinetics and thereby promoting the adsorption rate and capacity. Furthermore, the dynamic adsorption experiments of organic dyes from solutions showed selectivity/priority of CTF-PO71s for specific dye molecules.

Background

Endometrial cancer (EC) is one of the most common gynecological cancers. Epithelial–mesenchymal transition (EMT) is believed to be significantly associated with the malignant progression of tumors. However, there is no relevant study on the relationship between EMT-related gene (ERG) signatures and the prognosis of EC patients.

Methods

We extracted the mRNA expression profiles of 543 tumor and 23 normal tissues from The Cancer Genome Atlas database. Then, we selected differentially expressed ERGs (DEERGs) among these mRNAs. Next, univariate and multivariate Cox regression analyses were performed to select the ERGs with predictive ability for the prognosis of EC patients. In addition, risk score models were constructed based on the selected genes to predict patients’ overall survival (OS), progression-free survival (PFS), and disease-free survival (DFS). Finally, nomograms were constructed to estimate the OS and PFS of EC patients, and pan-cancer analysis was performed to further analyze the functions of a certain gene.

Results

Six OS-, ten PFS-, and five DFS-related ERGs were obtained. By constructing the prognostic risk score model, we found that the OS, PFS, and DFS of the high-risk group were notably poorer. Last, we found that AQP5 appeared in all three gene signatures, and through pan-cancer analysis, it was also found to play an important role in immunity in lower grade glioma (LGG), which may contribute to the poor prognosis of LGG patients.

Conclusions

We constructed ERG signatures to predict the prognosis of EC patients using bioinformatics methods. Our findings provide a thorough understanding of the effect of EMT in patients with EC and provide new targets and ideas for individualized treatment, which has important clinical significance.

As one of the most malicious cancers, pancreatic cancer is difficult to treat due to the lack of effective early diagnosis. Therefore, it is urgent to find reliable diagnostic and predictive markers for the early detection of pancreatic cancer. In recent years, the detection of circulating cell-free DNA (cfDNA) methylation in plasma has attracted global attention for non-invasive and early cancer diagnosis. Here, we carried out a genome-wide cfDNA methylation profiling study of pancreatic ductal adenocarcinoma (PDAC) patients by methylated DNA immunoprecipitation coupled with high-throughput sequencing (MeDIP-seq). Compared with healthy individuals, 775 differentially methylated regions (DMRs) located in promoter regions were identified in PDAC patients with 761 hypermethylated and 14 hypomethylated regions; meanwhile, 761 DMRs in CpG islands (CGIs) were identified in PDAC patients with 734 hypermethylated and 27 hypomethylated regions (p-value < 0.0001). Then, 143 hypermethylated DMRs were further selected which were located in promoter regions and completely overlapped with CGIs. After performing the least absolute shrinkage and selection operator (LASSO) method, a total of eight markers were found to fairly distinguish PDAC patients from healthy individuals, includingTRIM73,FAM150A,EPB41L3,SIX3,MIR663,MAPT,LOC100128977, andLOC100130148. In conclusion, this work identified a set of eight differentially methylated markers that may be potentially applied in non-invasive diagnosis of pancreatic cancer.

Horseshoe crabs are a group of marine chelicerates that contain only four extant species, some of which are endangered. Their hemolymph has been widely used in medical applications for endotoxin detection. Nevertheless, there is limited information on the profiles of their hemolymph proteins and their gut microbial diversity. In this study, we performed the first detailed investigation of the hemolymph proteomics and gut microbiota of two Asian horseshoe crabs Tachypleus tridentatus and Carcinoscorpius rotundicauda. Among the identified proteins being cataloged in the juvenile and adult hemolymph, unexpectedly, sesquiterpenoid signaling pathway proteins including Heat shock protein 83 (HSP83), Chd64, and a juvenile hormone binding protein (JHBP) were revealed. This provides evidence for the presence of functional sesquiterpenoid hormonal systems in these marine chelicerates. consumption of certain horseshoe crab species often leads to tetrodotoxin poisoning and the horseshoe crab is thought to possess a tetrodotoxin resistance mechanism. As such, sodium channels were analyzed and found to have critical amino acid residues that are similar to the toxin resistant pufferfish sodium channels. The source of the toxin is unknown so we investigated the gut microbiota, and found that Clostridium and Vibrio were the most dominant bacteria in T. tridentatus and C. rotundicauda, respectively. Together, this study provides a framework for further understanding of sesquiterpenoids and gut microbiota of these marine chelicerates.

Renal interstitial fibrosis is a common lesion in the process of various progressive renal diseases. Interleukin (IL)-18 is a proinflammatory cytokine that plays an important role in the induction of Th1 responses and is associated with renal interstitial fibrosis, but the mechanism of fibrosis remains unclear. Here we used IL-18 receptor alpha knockout (IL-18Rα KO) mice to investigate the role of an IL-18Rα signaling pathway in renal fibrosis in a murine model of unilateral ureteral obstruction. IL-18 Rα KO mice showed decreased renal interstitial fibrosis and increased infiltration of CD4+ T cells and Foxp3+ regulatory T cells (Tregs) compared to wildtype (WT) mice. The expression of renal transforming growth factor beta 1 (TGF-β1, which is considered an important cytokine in renal interstitial fibrosis) was not significantly different between WT and IL-18Rα KO mice. The adoptive transfer of CD4+ T cells from the splenocytes of IL-18Rα KO mice to WT mice reduced renal interstitial fibrosis and increased the number of Foxp3+ Tregs in WT mice. These results demonstrated that Foxp3+ Tregs have a protective effect in renal interstitial fibrosis via an IL-18R signaling pathway.
A Novel Family of Acinetobacter Mega-Plasmids Are Disseminating Multi-Drug Resistance Across the Globe While Acquiring Location-Specific Accessory Genes

Acinetobacter species are emerging as major nosocomial pathogens, aided by their ability to acquire resistance to all classes of antibiotics. A key factor leading to their multi-drug resistance phenotypes is the acquisition of a wide variety of mobile genetic elements, particularly large conjugative plasmids. Here, we characterize a family of 21 multi-drug resistance mega-plasmids in 11 different Acinetobacter species isolated from various locations across the globe. The plasmid family exhibits a highly dynamic and diverse accessory genome, including 221 antibiotic resistance genes (ARGs) that confer resistance to 13 classes of antibiotics. We show that plasmids isolated within the same geographic region are often evolutionarily divergent members of this family based on their core-genome, yet they exhibit a more similar accessory genome. Individual plasmids, therefore, can disseminate to different locations around the globe, where they then appear to acquire diverse sets of accessory genes from their local surroundings. Further, we show that plasmids from several geographic regions were enriched with location-specific functional traits. Together, our findings show that these mega-plasmids can transmit across species boundaries, have the capacity for global dissemination, can accumulate a diverse suite of location-specific accessory genes, and can confer multi-drug resistance phenotypes of significant concern for human health. We therefore highlight this previously undescribed plasmid family as a serious threat to healthcare systems worldwide. These findings also add to the growing concern that mega-plasmids are key disseminators of antibiotic resistance and require global surveillance.
Noise-Correlation Is Modulated by Reward Expectation in the Primary Motor Cortex Bilaterally During Manual and Observational Tasks in Primates

Reward modulation is represented in the motor cortex (M1) and could be used to implement more accurate decoding models to improve brain-computer interfaces (BCIs; Zhao et al., 2018). Analyzing trial-to-trial noise-correlations between neural units in the presence of rewarding (R) and non-rewarding (NR) stimuli adds to our understanding of cortical network dynamics. We utilized Pearson’s correlation coefficient to measure shared variability between simultaneously recorded units (32–112) and found significantly higher noise-correlation and positive correlation between the populations’ signal- and noise-correlation during NR trials as compared to R trials. This pattern is evident in data from two non-human primates (NHPs) during single-target center out reaching tasks, both manual and action observation versions. We conducted a mean matched noise-correlation analysis to decouple known interactions between event-triggered firing rate changes and neural correlations. Isolated reward discriminatory units demonstrated stronger correlational changes than units unresponsive to reward firing rate modulation, however, the qualitative response was similar, indicating correlational changes within the network as a whole can serve as another information channel to be exploited by BCIs that track the underlying cortical state, such as reward expectation, or attentional modulation. Reward expectation and attention in return can be utilized with reinforcement learning (RL) towards autonomous BCI updating.
