Image‐driven electronic identification keys for invasive plant species in the Netherlands

Field: Agricultural and Biological Sciences (Life Sciences)

For several years work has been ongoing to compile information to facilitate the identification of non‐native plants that (potentially) pose a threat to the biodiversity of the ecozone comprising Northern Germany, the Netherlands, Belgium and North‐Western France. Such identification information may also be used for species that are regulated by other countries and are likely to be present as contaminants in commercial exports originating from the Netherlands. This information system comprises a set of interactive image‐driven identification keys for invasive plants at various growth stages for use in a range of different situations: seed contaminants in bird feed, weeds in bonsai plants, seedling identification, identification keys of invasive terrestrial plants and invasive aquatic plants. The advantage of image‐driven identification keys using a multiple entry system lies in limiting misunderstandings in terminology and failure in identification, in the absence of certain characters, as is sometimes the case in dichotomous keys. The interactive keys are linked to the species information in the Q‐bank database, including datasheets, worldwide distribution maps, specimen level information, barcodes of selected species, etc. This information is now available at http://www.q-bank.eu/Plants/
Dynamic state estimation method of urban electricity-gas-heat coupled energy network based on multiple time scales

Field: Energy (Physical Sciences)

Under the background of the modern energy systems, the degree of interconnection and coupling between the power system and natural gas systems is gradually increasing. The economic dispatch model is becoming more and more complex. However, the economic dispatch of an integrated energy system is a high-dimensional, multi-period optimization problem, especially the multi-period joint optimization will greatly reduce the convergence speed of the model. Moreover, the electric power system and the natural gas system belong to two independent systems, which have a limited understanding of each other's information changes. In this paper, the cost of comprehensive operation is considered, and then the objective function is modeled. Based on the idea of k-means clustering, a granularity partition algorithm, which is based on the improved k-means clustering, is designed. To improve this algorithm, this paper adopts the shortest distance method to cluster the original data. Then, it adopts the rough clustering results to calculate the clustering center, and then applies the k-means clustering. From the source side heating coupling optimization and the load side load curve, the introduction of an air source heat pump at the source side and the consideration of waste heat recovery of electricity to the gas device can improve the flexibility of energy supply mode and optimize the heat supply coupling at the source site. Besides, it can equivalently decouple the problem of wind curtailment caused by the constraint of "determining power by heat" in co-generation, realize electric energy substitution and reduce the carbon emission of co-generation. Based on the principle of calorific value equivalence, the load side analyzes the energy conversion value of electric and thermal users and forms a comprehensive demand response mechanism with energy substitution under the guidance of various energy price signals to assist wind power integration and consumption. Through the coordination and optimization of source and load, the phenomenon of wind power curtailment is significantly reduced while ensuring the economic operation of the system.
Polariton condensation with saturable molecules dressed by vibrational modes

Field: Physics and Astronomy (Physical Sciences)

Here, polaritons, mixed light-matter quasiparticles, undergo a transition to a condensed, macroscopically coherent state at low temperatures or high densities. Recent experiments show that coupling light to organic molecules inside a microcavity allows condensation at room temperature. The molecules act as saturable absorbers with transitions dressed by molecular vibrational modes. Motivated by this, we calculate the phase diagram and spectrum of a modified Tavis-Cummings model, describing vibrationally dressed two-level systems, coupled to a cavity mode. Coupling to vibrational modes can induce re-entrance, i.e. a normal-condensed-normal sequence with decreasing temperature and can drive the transition first-order.
The Stabilization of Episomal Integration by Genetic Inversion: A General Hypothesis

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

In F′ cells of Escherichia coli K12, recombination in the region of genetic duplication between chromosome and F-genote produces a rapid alteration between the integrated and detached states of the episome. Nevertheless, F′ strains can give rise to Hfr cells in which the F-genote has undergone stable integration. We have found that one such Hfr has retained the genetic duplication as well as the recombination proficiency of the parental F′ strain; to account for the failure of recombination to detach the episome in this Hfr, we have postulated the inversion of one of the duplicated regions. A general model is presented, showing that an inversion must prevent episome detachment by any combination of genetic crossovers.
RE-EMERGENCE OF PANAMA DISEASE (FUSARIUM WILT) AND SPECIAL THREAT POSED BY TROPICAL RACE 4

Field: Agricultural and Biological Sciences (Life Sciences)

Panama disease is the most important lethal disease of banana. The causal soilborne fungus, Fusarium oxysporum f. sp. cubense (Foe), is found in most banana-producing regions and is pathologically and genetically diverse. Races of Foe, which affect different groups of cultivars, have been useful for describing host reactions and new disease outbreaks. Races 1 and 2 are heterogeneous, whereas populations of the pathogen that affect the Cavendish subgroup are more homogeneous; they are separated into subtropical race 4 (SR4), which causes damage only where cold winter temperatures occur, and tropical race 4 (TR4), which causes damage in the absence of predisposing conditions. TR4 is decimating Cavendish monocultures in southern Asia and would affect 85% of the global production of banana were it disseminated more widely. TR4's competence under tropical conditions and the wide range of cultivars that it affects make it a serious threat to export and small-holder production worldwide. This article summarizes the early history of, and research on, Panama disease, reviews its current status in different producing regions and recent research developments, and concludes with a discussion of TR4 diagnosis, interdiction, and control. Where TR4 has become established, it presents a most difficult management problem. There is an urgent need for innovative and useful research since the available management tactics are not very effective. If TR4 were to become established in the Western Hemisphere, radical changes would be needed in the American Cavendish-based export trades.
Efficient Market Managers

Field: Economics, Econometrics and Finance (Social Sciences)

We examine the effect of the Efficient Market Hypothesis (EMH) on the investment behavior of mutual fund managers. We show that managers who are more likely to be exposed to the ideas of EMH throughout their higher education are more “passive” than their unexposed peers: they are more likely to manage index funds, and when managing active funds, they hold portfolios with larger numbers of stocks and deviate less from their investment benchmarks. Exposed managers, however, take more systematic risks. Although academic exposure to the EMH does not result in better performance, it helps professional investors generate capital inflows.
Salicylic acid in the physiological priming of onion seeds subjected to water and salt stresses

Field: Agricultural and Biological Sciences (Life Sciences)

ABSTRACT This study aimed to evaluate the effect of physiological priming with salicylic acid on the mitigation of water and salt stresses on onion (Allium cepa L.) seeds. For this, seeds of onion, cultivar IPA 11, were soaked in salicylic acid solution (50 µM) for 24 h and placed to germinate at different water and saline potentials. For water stress, the experiment was conducted in a completely randomized design, in a 2 x 5 factorial scheme (salicylic acid with 0 and 50 µM and osmotic potentials of 0, -0.1, -0.2, -0.3, -0.4 MPa induced by polyethylene glycol 6000), with four repetitions of 50 seeds per plot. In salt stress, the adopted experimental design was completely randomized, with treatments distributed in a 2 x 4 factorial scheme (salicylic acid at concentrations of 0 and 50 µM and the osmotic potentials of 0, -0.3, -0.6 and -0.9 MPa induced by NaCl), in four repetitions of 50 seeds. For both experiments, germination, growth and accumulation of organic solutes were evaluated. Salicylic acid did not stimulate the germination of onion seeds in the absence of stress, but the application of 50 µM of salicylic acid increased the germination speed, growth and dry matter accumulation under conditions of water and salt stress. Onion plants were efficient in performing osmotic adjustment up to the potentials of -0.2 MPa induced by PEG 6000 under water stress and of -0.4 MPa induced by NaCl under salt stress.
Stereotactic Thalamotomy for Task‐Specific Dystonia

Field: Medicine (Health Sciences)

Abstract View Supplementary Video 1 View Supplementary Video 2 Background Task‐specific dystonia ( TSD ) is a focal dystonia producing abnormal posture of the fingers or the hand, occurring during selective motor activities that involve repeated use. Conventional medical management and botulinum toxin fail to provide relief in all patients. Thalamotomy or DBS have been used as surgical treatment in patients not responding to medical treatment. Methods Five patients (all male; age, 18–47 years) with refractory focal hand dystonia underwent ventrooralis (Vo) thalamotomy using stereotactic techniques. Preoperative video recordings, Writer's Cramp Rating Scale ( WCRS ), and Symptom Severity Scores ( SSS ) were evaluated at the baseline and at a follow‐up date, which ranged between 8 and 44 months (average, 26 months). Results All the patients had difficulty in performing their most common tasks. Duration of symptoms ranged from 6 months to 12 years. All patients obtained immediate postoperative relief from dystonic symptoms, and the effect was sustained during the follow up period. The WCRS improved from a mean of 20.4 before surgery to a mean of 2.4 at the last follow‐up, whereas the SSS improved from a mean of 29.8 before surgery to a mean of 12 at the last follow‐up. All patients were able to carry out their specific task with little or no difficulty. There were no surgical complications, morbidity, or mortality. Conclusions Vo thalamotomy is a safe and effective procedure providing successful symptom relief in patients of TSD .
The clinical and electrophysiological characteristics of nonsustained repetitive monomorphic ventricular tachycardia from the left His‐Purkinje system

Field: Medicine (Health Sciences)

Abstract Background Repetitive monomorphic ventricular tachycardia (RMVT) arising from the left His‐Purkinje system can occasionally be encountered during clinical practice. We describe eight cases as a unique entity in this study to characterize the clinical and electrophysiological features of the patients. Methods Eight patients with frequent palpitation (five men with median age of 28 years) were included in the study from January 2003 to July 2018. Twelve‐lead ECG (Electrocardiogram), Holter, and echocardiographic tests were performed after medical history interrogations and physical examinations. Antiarrhythmic drug therapy was essential to all patients, and catheter ablation was attempted if the patients could not tolerate or were not responsive to drug therapy. Results No patients had a history of syncope and a family history of sudden cardiac death. ECGrecording was characterized by frequent ventricular extrasystoles, ventricular couplets, and salvos of nonsustained VT competitive with sinus rhythm. The QRS morphology of ectopic beats was in the right bundle branch block pattern with severe left axis deviation. The width of the QRS complex from ECG was 135 ms (120‐140) during ventricular tachycardia. Verapamil had no effect on all VT individuals. Enlargement of the left ventricle was found in two patients. Four out of six cases were successful with catheter ablation treatment. Conclusion RMVT arising from the left His‐Purkinje system is a special arrhythmic and nonverapamil‐sensitive entity. The electrophysiological mechanism of this treatment appears to be focal firing, which is amendable to catheter ablation in symptomatic and high‐burden patients.
Bandsaw diagnostics by neurocomputing-two are better than one!

Field: Engineering (Physical Sciences)

In industrial sawmills, bandsaws must work at a high production rate. Two major factors which limit cutting performance are cracking and instability of the saw blades. This paper describes the results from the development of a diagnostic system which monitors blade vibration and blade tension sensor data to estimate crack length using neurocomputing techniques, to help predict blade failure. It was found that a multi-layered feedforward artificial neural network with two hidden layers produces the most reliable results. The results indicate that this system should enable the detection of cracking in blades while in a running but unloaded (between cuts) state. This may help allow longer run times to be planned with confidence increasing production uptime and minimising maintenance.
Coherent phase locking, collective oscillations, and stability in coupled vertical-cavity-surface emitting laser arrays

Field: Physics and Astronomy (Physical Sciences)

Closely packed vertical-cavity-surface emitting laser arrays support collective modes via nearest-neighbor interactions. Nonlinear cavity-lattice dynamic equations are introduced through the derivation of intercavity coupling coefficients based on microscopic transition probabilities and the tight-binding approximation for lattice eigenstates. Ultrafast numerical simulations show array relaxation to phase-locked steady-state configurations, of fixed phase difference among nearest neighbors. Linear stability analysis derives the dispersion relation of the collective modes excited over the cavity lattice, their stability regimes, and transitions to limit cycles and chaotic behavior at high coupling strengths. Spontaneous phase selection is also analyzed.
SH1885756.08FU

Field: Agricultural and Biological Sciences (Life Sciences)

UNITE provides a unified way for delimiting, identifying, communicating, and working with DNA-based Species Hypotheses (SH). All fungal ITS sequences in the international nucleotide sequence databases are clustered to approximately the species level by applying a set of dynamic distance values (<0.5 - 3.0%). All species hypotheses are given a unique, stable name in the form of a DOI, and their taxonomic and ecological annotations are verified through distributed, web-based third-party annotation efforts. SHs are connected to a taxon name and its classification as far as possible (phylum, class, order, etc.) by taking into account identifications for all sequences in the SH. An automatically or manually designated sequence is chosen to represent each such SH. These sequences are released (https://unite.ut.ee/repository.php) for use by the scientific community in, for example, local sequence similarity searches and next-generation sequencing analysis pipelines. The system and the data are updated automatically as the number of public fungal ITS sequences grows.

Consumption disparities in information society

Field: Social Sciences (Social Sciences)

Purpose This article compares consumption differences between population groups in the fields of the traditional and new information and entertainment. The interest is to estimate to what extent traditional information and entertainment expenditure and expenditure on the new information technology display similar structural characteristics. Design/methodology/approach The data used is the Finnish Expenditure Survey data from 1998 ( N =4359) and 2001‐2002 ( N =5495) provided by the Statistics Finland. The information and entertainment consumption is studied by using purchasing costs of books and magazines, television license and pay channel costs, video rentals, and operating costs of phone and internet services. The differences by population groups are analysed according to the respondent's level of education and income, type of household, respondent's age and gender, and place of residence. Findings The findings indicate that the differences concerning books and magazines and especially phone and internet services have increased in the 21st century. Research limitations/implications The conclusions presented in this article are connected with circumstances during and after the product consolidation in Finland. In this regard it should be stated that the empirical analysis was restricted to the use of variables including different operating costs and to a short time frame in one European country. Practical implications The findings indicate that consumption disparities display the same structural characteristics in the realms of both traditional information technology (books and magazines) and new information technology (phone and internet services). Despite the fact that new technology is apparently available to everyone, growing disparities are displayed by both education and income. Originality/value This paper compares the traditional and digital divides in Finland to display the structural similarities and differences.
Nursing education in labour and delivery: the learning environment that builds self efficacy and fosters undergraduate nursing student learning

Field: Nursing (Health Sciences)

Statement of the problem The clinical learning environment in obstetrics is a complex entity. Teaching intrapartum care is challenging in undergraduate nursing education as students may not be able to actively assist mothers during delivery or even potentially be at the site when mothers deliver. Given the potential for rapid progression of care in the delivery room, combined with high risk of adverse outcomes, undergraduate nursing students are unlikely to be able to actively participate in the delivery of care or apply their clinical skills in an obstetrical clinical rotation. However, students can fully and actively participate in obstetrical simulation-based learning activities. The study explored undergraduate nursing student’s perspective of the learning environment that fosters the development of self-efficacy in labour and delivery nursing education. Methods To better understand undergraduate nursing student’s perspective on the learning environment that fosters the development of self-efficacy in labour and delivery education, a qualitative descriptive methodology was used. Eight (8) voluntary students participated in a semi-structured interview consisting of 12 open-ended questions that provided data on the nursing students’ perspective of which learning environment fosters self-efficacy in caring for women and their families in the labour and delivery context (see Appendix B). Results The participants of the study identified three themes that influenced students perceptive of the learning environments in obstetrics. theses are feeling supported, knowledge and skills, and the learning experiences. Conclusion A learning environment that incorporates all the sources of self efficacy enhances student learning. Keywords: obstetrics, classroom environment, simulated environment, traditional environment, labour and delivery, maternal and child health, learning needs, self- efficacy.
Genomic-assisted characterisation of Pseudomonas sp. strain Pf4, a potential biocontrol agent in hydroponics

Field: Agricultural and Biological Sciences (Life Sciences)

In an attempt to select potential biocontrol agents against Pythium spp. and Rhizoctonia spp. root pathogens for use in soilless systems, 12 promising bacteria were selected for further investigations. Sequence analysis of the 16S rRNA gene revealed that three strains belonged to the genus Enterobacter, whereas nine strains belonged to the genus Pseudomonas. In in vitro assays, one strain of Pseudomonas sp., Pf4, closely related to Pseudomonas protegens (formerly Pseudomonas fluorescens), showed noteworthy antagonistic activity against two strains of Pythium aphanidermatum and two strains of Rhizoctonia solani AG 1-IB, with average inhibition of mycelial growth >80%. Strain Pf4 was used for in vivo treatments on lamb’s lettuce against R. solani root rot in small-scale hydroponics. Pf4-treated and untreated plants were daily monitored for symptom development and after two weeks of infection, a significant protective effect of Pf4 against root rot was recorded. The survival and population density of Pf4 on roots were also checked, demonstrating a density above the threshold value of 105 CFU g−1 of root required for disease suppression. Known loci for the synthesis of antifungal metabolites, detected using PCR, and draft-genome sequencing of Pf4 demonstrated that Pseudomonas sp. Pf4 has the potential to produce an arsenal of secondary metabolites (plt, phl, ofa and fit-rzx gene clusters) very similar to that of the well-known biocontrol P. protegens strain Pf-5.
