Microbial community dynamics in the recirculating nutrient solution of tomato plug seedlings cultivated under ebb-and-flow system

Background: The ebb-and-flow system has ability to recirculate water and nutrients, and offers a good method to control nutrient leaching from greenhouses into the environment. However, the potential for the rapid spread of bacterial and fungal pathogens is the main hindrance for its adoption in vegetable seedlings production. Natural microflora has often shown a certain ability to suppress diseases.Results: Here, through 16S rRNA- and ITS1-targeted Illumina sequencing, the dynamic changes in bacterial and fungal communities in the recirculating nutrient solution were characterized for tomato plug seedlings cultivated in an ebb-and-flow system in summer and winter. Both bacterial number and microbial diversity in the nutrient solution increased with recirculating irrigation, and these changes differed between summer and winter. Pseudomonas was among the most predominant bacterial genera in the nutrient solution; its relative abundance gradually increased with recycling in summer but decreased dramatically in winter. In summer, the predominant bacteria also included Comamonas and Sediminibacterium , whose relative abundances in the nutrient solution decreased and increased, respectively. In winter, the nutrient solution was also colonized by Sphingomonas , predominantly at the late stage of irrigation. Among fungi, Amanita and Trichoderma were predominant in both summer and winter. Amanita gradually increased in summer but decreased rapidly after the first irrigation cycle in winter, whereas Trichoderma accumulated rapidly at the late stage of irrigation in both summer and winter. Alternaria and Fusarium were predominant in the nutrient solution only in summer, with the former decreased and the latter increased with recirculating irrigation. Moreover, Pseudomonas mediterranea , a potentially pathogenic bacterium, and Fusarium oxysporum , a fungal pathogen were present predominantly in winter and summer, respectively. Some potentially beneficial microbes functioning in plant-growth promotion and water self-purification, such as Sphingobium xenophagum , Trichoderma harzianum , and T. virens , were identified to be increased in the recirculating nutrient solution.Conclusions: The present data elucidate the bacterial and fungal dynamics in an ebb-and-flow system and provide useful information for pathogen control during tomato seedling production.
Covering the global threat landscape DEXOFUZZY: ANDROID MALWARE SIMILARITY CLUSTERING METHOD USING OPCODE SEQUENCE

Recently, Android malware has shown a tendency towards large-scale distribution, which reduces the amount of time required for stealing data. Hackers implement such malicious code variants by reusing code. This paper proposes the use of the ‘Dalvik EXecutable Opcode Fuzzy’ (‘Dexofuzzy’) hash, which fi nds similar malware variants without the need for an analyst to have systematic or mathematical knowledge. Dexofuzzy is a method for generating similarity digests with software birthmarking of opcode sequences in Dex fi les based on ssdeep. The clustering results are obtained by N-gram tokenizing of the Dexofuzzy hash, which is generated from the malware samples. Observations and experimental results have demonstrated the effectiveness of Dexofuzzy’s similarity search in analysing the Android malware ‘Operation Blackbird’, which had previously been reported by ESTsecurity Security Response Center (ESRC). Finally, we have measured the similarity of the indicators of compromise (IOCs) in 74 reports published by AlienVault OTX and analysed the association between each report in order to attest the effi ciency of Dexofuzzy.
The scope in the INTELCITIES project for the use of the 3D laser scanner

The difficulty in visualising 2D plans of building elements and components brings about errors in interpreting design specifications in terms of accuracy, completeness. Besides, accessibility is another major problem encountered by surveyors. A number of strategies have been set out to improve efficiency and quality of design within the built environment. One of them is the new innovation of 3D laser scanning technology, which has come about and can be used to improve the efficiency and quality design. It has enormous potential to benefit for refurbishment process. The scanner can digitise all the 3D information concerned with a building down to millimetre detail. A series of scans externally and internally allows an accurate 3D model of the building to be produced. This model can be "sliced" through different planes to produce accurate 2D plans and elevations. This novel technology improves the efficiency and quality of construction projects, such as maintenance of buildings or group of buildings that are going to be renovated for new services. This paper describes the generation of 2D and 3D CAD plans of existing buildings. It explains the generation of interior and exterior 2D and 3D CAD plans of the existing facilities. Furthermore, it presents the use of 3D laser scanner in integration with other VR systems such VR workbenches for visualisation, analysis and interaction with a VR model of existing buildings.

Personalized drug-response prediction model for lung cancer patients using machine learning

Lung cancer caused by mutations in the epidermal growth factor receptor (EGFR) is a major cause of cancer deaths worldwide. EGFR Tyrosine kinase inhibitors (TKIs) have been developed, and have shown increased survival rates and quality of life in clinical studies. However, drug resistance is a major issue, and treatment efficacy is lost after about an year. Therefore, predicting the response to targeted therapies for lung cancer patients is a significant research problem. In this work, we address this issue and propose a personalized model to predict the drug-response of lung cancer patients. This model uses clinical information, geometrical properties of the drug binding site, and the binding free energy of the drug-protein complex. The proposed model achieves state of the art performance with 97.5% accuracy, 100% recall, 95% precision, and 96.3% F1-score with a random forest classifier. This model can also be tested on other types of cancer and diseases, and we believe that it may help in taking optimal clinical decisions for treating patients with targeted therapies

Designing a Technical System - Deliverables of a Process

Many students of the science and engineering faculties of the University of Twente finish their bachelor’s programme with an individual research assignment of typically 1 to 3 months. These assignments are often evaluated on skills that are implicitly taught during the assignment itself. In order to improve this improper situation, it was decided to explicitly include the topic ‘designing a technical system’ in one of the courses preceding the research assignment. The complexity of the many steps the student has to take hold of during the assignment should not be underestimated. Therefore a step-bystep approach is presented in this paper for any typical process of designing a technical system. The different processes to come to the final design are discussed and the deliverable per process is mentioned. The design process is based on partitioning the main function of the system to be designed in smaller functions that can be implemented by subsystems. The whole design process is guided by clearly stated deliverables, being the hold on for the students to finalize successfully their research assignment. The design process proposed in this paper is illustrated with the design of a sensor system for water quality monitoring.

Different spectra are produced and their properties are measured. Further study explores possible ways in suppressing the spectrum and means to quantify the spectrum. The implications that signal bandwidth and power have on the possible applications of the technique are also considered.
Maneuver Load Controls, Analysis and Design for Flexible Aircraft

L'obiettivo principale della Tesi di Dottorato e stato quello di definire metodologie numeriche per il disegno e l’analisi di un sistema di alleviazione del carico di manovra che tenga conto dell’elasticita della struttura, nonche di quantificare i benefici derivanti dall’utilizzo di tali sistemi in termini di allungamento della vita a fatica. Le metodologie sviluppate sono di tipo teorico/numerico. Nel corso del primo anno e stata messa a punto una metodologia per il calcolo dei parametri di equilibrio del velivolo elastico in manovra quasi-statica bilanciata ed un metodo per ridurre il carico strutturale alare. Nel corso del secondo anno e stata messa a punto una metodologia per il calcolo dell’efficacia aeroelastica di una superficie mobile quando essa e utilizzata per alleviare il carico da manovra simmetrica non stazionaria. L’attivita del terzo anno e consistita nel disegno concettuale di un sistema automatico di controllo dei carichi da manovra in volo longitudinale. E’ stata definita l’architettura del sistema aero-servo-elastico a loop chiuso per il controllo simultaneo del fattore di carico e del momento flettente nella stazione dell’ala piu sollecitata. Sono state eseguite applicazioni numeriche su velivolo a configurazione non convenzionale e a configurazione classica (joined-wing UAV e CS-25 business jet). Infine, e stato stimato il miglioramento della vita a fatica derivante dall’utilizzo di un sistema automatico di controllo dei carichi, per elementi strutturali alari dimensionati a momento flettente. I risultati numerici ottenuti in termini di riduzione del carico di manovra sono rilevanti. Sono state registrate diminuzioni del momento flettente alla radice alare fino ad oltre il 30%, sia in caso di velivoli a configurazione fortemente non convenzionale (joined-wing), sia in caso di velivoli classici. La principale limitazione della metodologia consiste nel fatto che il carico e osservato e controllato in un’unica stazione alare, generalmente la piu caricata che, in caso di architetture fortemente non convenzionali, potrebbe non coincidere con la radice alare. Tuttavia e possibile generalizzare il metodo introducendo altre superfici mobili dedicate all’alleviazione del carico per il controllo simultaneo in piu stazioni. Appare difficile che sistemi di “load control” possano portare alla riduzione del peso strutturale data la reticenza degli Enti Certificanti ad accettare che la progettazione strutturale sia eseguita “a carico ridotto” senza prevedere eccessive ridondanze dei sistemi. D’altro canto l’allungamento della vita a fatica costituisce un beneficio di fortissimo interesse industriale. Sono stati stimati allungamenti della vita a fatica fino ad oltre il 50%, per elementi strutturali dimensionati a momento flettente.
Physics-, social-, and capability- based reasoning for robotic manipulation

Robots that can function in human-centric domains have the potential to help humans with the chores of everyday life. Moreover, dexterous robots with the ability to reason about the maneuvers they execute for manipulation tasks can function more autonomously and intelligently. This thesis outlines the development of a reasoning architecture that uses physics-, social-, and agent capability-based knowledge to generate manipulation strategies that a dexterous robot can implement in the physical world. The reasoning system learns object affordances through a combination of observations from human interactions, explicit rules and constraints imposed on the system, and hardcoded physics-based logic. Observations from humans performing manipulation tasks are also used to develop a unique manipulation repertoire suitable for the robot. The system then uses Bayesian Networks to probabilistically determine the best manipulation strategies for the robot to execute on new objects. The robot leverages this knowledge during experimental trials where manipulation strategies suggested by the reasoning architecture are shown to perform well in new manipulation environments.

Unique active site formation in a novel galactose 1‐phosphate uridylyltransferase from the hyperthermophilic archaeon Pyrobaculum aerophilum

A gene encoding galactose 1‐phosphate uridylyltransferase (GalT) was identified in the hyperthermophilic archaeon Pyrobaculum aerophilum. The gene was overexpressed in Escherichia coli, after which its product was purified and characterized. The expressed enzyme was highly thermostable and retained about 90% of its activity after incubation for 10 minutes at temperatures up to 90°C. Two different crystal structures of P. aerophilum GalT were determined: the substrate‐free enzyme at 2.33 Å and the UDP‐bound H140F mutant enzyme at 1.78 Å. The main‐chain coordinates of the P. aerophilum GalT monomer were similar to those in the structures of the E. coli and human GalTs, as was the dimeric arrangement. However, there was a striking topological difference between P. aerophilum GalT and the other two enzymes. In the E. coli and human enzymes, the N‐terminal chain extends from one subunit into the other and forms part of the substrate‐binding pocket in the neighboring subunit. By contrast, the N‐terminal chain in P. aerophilum GalT extends to the substrate‐binding site in the same subunit. Amino acid sequence alignment showed that a shorter surface loop in the N‐terminal region contributes to the unique topology of P. aerophilum GalT. Structural comparison of the substrate‐free enzyme with UDP‐bound H140F suggests that binding of the glucose moiety of the substrate, but not the UDP moiety, gives rise to a large structural change around the active site. This may in turn provide an appropriate environment for the enzyme reaction.
A neural control of power factor preregulators

Application of artificial neural networks (ANN) in power factor preregulators (PFP) control is investigated. Both continuous conduction mode (CCM) and discontinuous conduction mode (DCM) converters are analyzed. At present the system gives good results for DCM in both static and dynamic conditions. For CCM good results are being obtained for static conditions. Simulation results indicate that the approach is viable and represents an alternative novel technique in PFP control. <<ETX>>

Account Deactivation and Content Removal: Guiding Principles and Practices for Companies and Users

This report explores these dilemmas and recommends principles, strategies, and tools that companies and users alike can adopt to mitigate the negative effects of account deactivation and content removal. Through case examples, we outline the ways in which platform providers can have a positive impact on user trust and behavior by being more clear and consistent in developing ToU and other policies, responding to and evaluating suspected violations, and providing opportunities for recourse and appeal. We also highlight concrete actions that users can take to educate themselves about how the moderation, takedown, and abuse-prevention mechanisms work for the services they use, provide and communicate context where necessary, and engage with companies and other users around such issues.This document grew out of an ongoing learning series hosted by the Global Network Initiative (GNI), of which the Berkman Center and CDT are founding members. Our analysis was strengthened by the experience and feedback of diverse stakeholders, including company representatives, socially responsible investors, academics, and advocates, and intends to offer realistic and concrete approaches that are rights-sensitive while also flexible enough to be practically implemented across diverse platforms and contexts.
Race, Class, and the Neoliberal Scourge

N eoliberalism, the broad set of ideas positing the market and marketcentered values as the ultimate “civilizing” agent at home and abroad, has now structured our society for forty years. Ever since it began its gradual ascendance in 1973, we have experienced a marked increase in income inequality, witnessed the slow death of the labor union movement, and keenly felt a growing sense of anxiety. The task of the American Left has never been simpler and clearer — it’s to reconstitute the very idea of the public, in the hope that this reconstitution will generate a largescale movement against neoliberalism. As they seek to put flesh on the bones of this antineoliberal project, some point to the worsening of economic inequalities following Obama’s election (and reelection) in arguing we should turn away from identity politics and back to class politics, this time with a spiritually informed base. I disagree. Race plays a prominent role in two aspects of the neoliberal turn — the rollback of progressive taxes and the rollback of welfare. We do need a more spiritually informed politics, but given how important the local terrain is in our political struggle, we need to understand the way “identity” and “class” politics come together.
Physiological correlates of simulated sprint-distance triathlon

The purpose of this study was to examine the relationship between simulated triathlon performance and physiological variables measured during conventional laboratory tests. Seven non-elite, competitive male triathletes completed incremental cycling and running tests in a random order, in addition to a simulated sprint-distance triathlon trial (750 m swim, 500 kJ bike, 5 km run) using a 25 m pool, an electromagnetically braked cycle ergometer and motorised treadmill. There were no significant correlations between overall performance time and either running or cycling incremental tests, however significant correlations were found between triathlon run time and both running and cycling incremental tests (Vpeak, r = -.900, p<0.05; V4mmol, r = -.822, p<0.05; Wpeak, r = -.844, p<0.05). Total simulated triathlon time was highly correlated to cycle time (r = .930, p<0.05) and mean cycling power output (r = -.956, p<0.05), whilst there was no significant correlation between either swim time or run time and overall performance time. For non-elite, competitive male triathletes, a performance assessment which better reflects the demands of the cycle phase of triathlon (i.e. a time-trial protocol) may provide a better indication of simulated sprint-distance triathlon performance in comparison to commonly used incremental laboratory tests. Furthermore, cycling performance appears more important to overall performance in simulated sprint-distance triathlon than swimming or running.
