Local theory of complex functional differential equations

We consider the equation (*) f '(z) = F(z, f(z), f (g(z))) where F(z, u, w) and g(z) are given analytic functions and f(z) is an unknown function. The question of local existence of a solution of (*) about a point z0 is natural only if g(zo)=zo. We classify fixed points z0 of g as attractive if Ig'(zo)I 1. In the attractive case (*) has a unique analytic solution satisfying an initial conditionf(zo) = w0. This solution depends continuously on w0 and on the functions F and g. For "most" indifferent fixed points the initial-value problem has a unique solution. Around a repulsive fixed point a solution in general does not exist, though in exceptional cases there may exist a singular solution which disappears if the equation is subjected to a suitable small perturbation. Introduction. A natural way of generalizing ordinary differential equations is to permit the argument of the unknown function to appear, in at least one term, as a function of the independent variable. A fairly wide class of such "functional differential equations" can be written in the form (*) f'(z) = F(z,f(z),f(g(z))) where F and g are given functions and f is an unknown function. The case of systems (and also higher order equations reducible to first order systems) can be included if we allow the functions F and f to be vector-valued. In the real case functional differential equations have been extensively studied, but for the complex case the literature is quite sparse. Flamant [2] studied the linear equation f'(z) = a(z)f(g(z)) + b(z) in the case where g(z) is a fractional linear transformation. Izumi [3] established existence theorems for the same equation where g(z) is an analytic function mapping the unit disc into itself. In a series of papers Robinson ([6]-[9] and others) obtained various results on certain special FDE. Leont'ev [5] considered differential-difference equations with constant coefficients in the complex case. But none of these papers seem really concerned Presented to the Society, January 23, 1970 under the title Local theory of fulnctional differential equiations over the complex plane; received by the editors June 16, 1970 and, in revised form, March 1, 1971.

A High Sensitive Approach for Gender Detection Based on Human Iris

Now a day’s iris patterns play a vital role in gender classification. Iris patterns are distinctive and cannot be changed until it becomes unnatural. This paper focus on gender has been detected using iris images. This work presents a new method for gender classification based on features of the iris texture selected by mutual information to improve gender classification of iris images For determining the recognition performance of the system database of digitized grayscale eye images were used. This grayscale images are segmented. Traditional iris segmentation methods always time-consuming and sensitive to noise. Here, in iris recognition, the segmentation is based on Hough transform used for automatic segmentation and able to localize the circular iris and pupil region. Edge points of iris boundaries are detected with canny edges steps and the threshold values are matched with the hamming distance. The Hamming distance was employed for classification of iris images. This work comes to the conclusion that iris segmentation is an essential part of recognition system and the prediction is based on iris texture features and stop matching when a generation of Iris close match is found.
An Expeditious Methodology to Assess the Effects of Intermittent Generation on Power Systems

This paper proposes an expeditious methodology that provides hourly assessments of the effect of intermittent wind and solar power generation on the electrical quantities characterizing power systems. Currents are measured via circuit breakers to confirm the correct sizing of devices based on their rated currents. Nodal voltage magnitudes are assessed for compliance with limits imposed by regulatory authorities, whereas the active power produced by hydroelectrical generators is assessed for reserve energy. The proposed methodology leverages a fuzzy extended deterministic optimal power flow that uses in power balance equations the average hourly values of active power generated by wind and solar sources as well as hourly energy load. The power grid is modeled at the substation level to directly obtain power flow through circuit breakers. Uncertainties in power system electrical quantities are assessed for an optimal solution using a Taylor series associated with deviations from the average values of the active power produced by the wind and solar sources. These deviations are represented using a fuzzy triangular model reflecting the approximations of the probability density functions of these powers. The methodology takes into account a subjective investigation that focuses on the qualitative characteristic of these energy sources’ behaviors.
Market Competition and Agency Problem: a Study in Indonesian Manufacturing Companies

This study analyzes agency problems in manufacturing companies’ investment decisions by considering market competition. Investment decisions are important for companies to survive, and more competitive companies are likely to conduct more risky activities, especially regarding capital expenditures for investments. This study uses the dynamic panel data method, which includes annual data of 100 listed manufacturing companies from 2007 to 2016. Results suggest that leverage improves management control functions, and competition increases a company’s investments to maintain its position in the market. Competition is not strengthened or weakened by sales growth and there are indications of herding behavior following market leaders.

Exogenous Foliar Application of Glycine Betaine to Alleviate Water Deficit Tolerance in Two Indica Rice Genotypes under Greenhouse Conditions

The aim of this investigation was to enhance overall growth, yield attributes as well as physio-biochemical adaptive strategies by exogenous foliar application of glycine betaine (GlyBet) in two rice varieties against water deficit stress under greenhouse conditions. Rice crop cvs. RD43 (low amylose content) and SPR1 (high amylose content) grown in clay pots containing garden soil until booting stage were chosen as the test plant material, sprayed by 0 (control) or 100 mM GlyBet and subsequently subjected to: MWD (mild water deficit by 8 d water withholding; 24.80% SWC; Soil water content) or SWD (severe water deficit by 14 d water withholding; 13.63% SWC) or WW (well-watered conditions or control). Free proline content in cv. RD43 was rapidly increased in relation to the degree of water deficit and suppressed by exogenous GlyBet, while free proline in cv. SPR1 was lower than cv. RD43. Overall growth performances and yield traits in both cultivars under MWD were maintained by exogenous application of GlyBet; however, these parameters declined under SWD even after the GlyBet application. Degradation of photosynthetic pigments and chlorophyll fluorescence in pretreated GlyBet plants under SWD were prevented, resulting in elevated net photosynthetic rate (Pn). Interestingly, Pn was very sensitive parameter that sharply declined under SWD in both RD43 and SPR1 genotypes. Positive relationships between physio-morphological and biochemical changes in rice genotypes were demonstrated with high correlation co-efficiency. Based on the key results, it is concluded that foliar GlyBet application may play an important role in drought-tolerant enhancement in rice crops.
Personalised reading for pleasure with digital libraries: Towards a pedagogy of practice and design

This paper discusses the pedagogical practice of developing reading for pleasure in pre- schools and primary phase settings through the lens of one key dimension of 21st century reading: personalisation. We draw on a series of studies and examples to identify, address and problematise human-and digitally-mediated personalised reading for pleasure. Through a content analysis of the key features of current digital library systems, we show how these increasingly popular systems position teachers as librarians, curators and monitors, and undermine their potential roles as listeners, mentors and co-readers in order to foster children’s personal response to texts. Through a theory-driven approach we identify ways in which current design limitations of library management systems can be addressed and from which their effective application and use can develop. This conceptual elaboration, which combines contemporary reading theories with the affordances of digital personalisation, provides new insights concerning personalisation in digital library systems.
Reducing delay in patients with acute coronary syndrome and other time-critical conditions: a systematic review to identify the behaviour change techniques associated with effective interventions

Background Time to treatment in many conditions, particularly acute coronary syndrome, is critical to reducing mortality. Delay between onset of symptoms and treatment remains a worldwide problem. Reducing patient delay has been particularly challenging. Embedding behaviour change techniques (BCTs) within interventions might lead to shorter delay. Objective To identify which BCTs are associated with reductions in patient delay among people with symptoms or conditions where time to treatment is critical. Methods The data sources were Cochrane Library, MEDLINE, EMBASE, Cumulative Index to Nursing and Allied Health Literature, and PsycINFO. Study eligibility criteria include intervention evaluations (randomised controlled trials, controlled clinical trials and cohort studies) involving adults (aged >18 years) and including an outcome measure of patient delay up to August 2016. Study appraisal and synthesis methods include screening potential studies using a transparent, replicable process. Study characteristics, outcomes and BCTs were extracted from eligible studies. Results From 39 studies (200 538 participants), just over half (n=20) reported a significant reduction in delay. 19 BCTs were identified, plus 5 additional techniques, with a mean of 2 (SD=2.3) BCTs and 2 (SD=0.7) per intervention. No clear pattern between BCTs and effectiveness was found. In studies examining patient delay specifically, three of four studies that included two or more BCTs, in addition to the two most commonly used additional techniques, reported a significant reduction in delay. Conclusions Around half of the interventions to reduce prehospital delay with time-critical symptoms report a significant reduction in delay time. It is not clear what differentiates effective from non-effective interventions, although in relation to patient delay particularly additional use of BCTs might be helpful.

Biocontrol of Leucoagaricus gongylophorus of leaf-cutting ants with the mycoparasitic agent Trichoderma koningiopsis

Leaf-cutting ants are one of the main agricultural and agroforestry pests in the Neotropic region. The essential food source of these ants is Leucoagaricus gongylophorus. Therefore one of the main biocontrol agents under study are Trichoderma species, because of their biocontrol activity against a diverse range of fungi. Here, Trichoderma koningiopsis, isolated from a leafcutting ants nest was tested against three Leucoagaricus gongylophorus strains from leaf-cutting ants by dual culture technique under laboratory conditions. The molecular analysis of ITS sequence data showed three well-separated main clades in which the isolated Trichoderma strain was assembled as a sole subclade among T. koningiopsis strains. The tests also showed that T. koningiopsis strain inhibited the growth of all L. gongylophorus strains tested. The values of radial inhibition of L. gongylophorus ranged from 58% to 69% with an average mean value of 65%. This is the first report on a strain of T. koningiopsis isolated from a naturally parasitized nest of leafcutting ants with biocontrol ability over L. gongylophorus tested in dual culturing method.
Natural Gas Security in China: A Simulation of Evolutionary Trajectory and Obstacle Degree Analysis

Studying the security status of China’s natural gas supply and proposing a feasible coping strategy for enhancing that security is of great significance. We use a pressure-state-response (PSR) analysis framework and the exponential weighting method to make a systematic evaluation of China’s natural gas security, predict the evolution of natural gas security combined with the GM(1,1) model, and use the obstacle degree model to diagnose the obstacles standing in the way of China’s optimum natural gas security. China’s natural gas comprehensive security index from 2006 to 2015 was between 0.627 and 0.740, and it is predicted to land between 0.669 and 0.759 from 2016 to 2025. The barriers affecting China’s natural gas security moving forward will be focused on urban development pressure, natural gas consumption growth pressure, supply-demand ratio, storage-production ratio, import price volatility for liquefied natural gas, and import dependence. We predict China’s natural gas security will be characterized by a wave of advancement, and has certain periodicity. The main internal factors affecting China’s natural gas security will shift from the rudimentary natural gas pipeline construction and gas storage facilities construction to the low availability of natural gas and urbanization, which will increase the pressure on natural gas supply and demand.
An examination of L2-L1 noncognate translation priming in the lexical decision task: insights from distributional and frequency-based analyses

The main fact that is currently known about the nature of masked L2-L1 noncognate translation priming effects in the lexical decision task is simply that those effects are significant in some studies but not in others. In an effort to better understand these effects, we examined the data pattern for very proficient Japanese–English bilinguals using RT distributional analyses. We also examined the impacts of prime and target frequency on the priming effect. Significant priming was present even on the fastest trials, becoming larger on slower trials. Nonetheless, priming effects were generally constant across prime and target frequency with the only exception being when very high frequency L2 primes were used. In that situation, priming and target frequency were negatively related, a result that essentially produced the observed pattern of increasing priming on slower trials. Implications of these results and potential reasons for the presence/absence of L2-L1 priming effects are discussed.
The use of stored tissue samples from minors for genetic research: interviews with professionals

Stored tissue sample collections from minors are useful for genetic research. The ethics of the use of stored tissue samples for genetic research continues be a much debated topic of discussion. The use of pediatric samples poses specific ethical questions. Although a substantial corpus of empirical literature exists on the use of samples from adults, not much is known about the opinion of professionals on the use of samples from children. We conducted ten interviews with professionals in the field. Their primary concerns were the fact that consent procedures should not be too bureaucratic, the need for proper research design and privacy protections, the fact that research should not burden children and guidance from ethics committees.
Multiple-Fidelity Modeling of Interactional Aerodynamics

The interaction of trailing vortices with lifting surfaces is investigated using two levels of modeling fidelity. An overset mesh-based Reynolds-averaged Navier–Stokes solver is considered as the high-fidelity computational model. A lower-fidelity model is developed by combining a vortex panel method with a propeller aerodynamic model and slipstream theory. The high-fidelity model is first validated against available experimental data obtained from the interaction of a trailing vortex generated by an upstream wing with a downstream wing. The ability of both models to represent the development of the vortex wake and integrated loads is assessed for a number of parametric configurations, including a case in which the vortex core directly impinges on the wing surface. Following this, isolated propeller and wing-mounted propeller configurations are studied. In all of these cases, the high-fidelity model is effective in predicting the details of the flow and integrated airloads. The low-fidelity model, althoug.
STATUS OF SHOCK LAYER RADIATION VALIDATION STUDIES

This paper presents a status update for the shock layer radiation validation studies conducted at NASA. A review of the present capability for the simulation and validation of shock layer radiation is presented as well as providing an overview of the data obtained from the Electric Arc Shock Tube (EAST). The paper will include details covering updated convective and radiative heating correlations, provide an overview of the development of new kinetics for Mars entry and detail some recent work calculating after-body radiation. Furthermore, the paper will highlight conditions where there is high confidence in the validation of EAST data (e.g. Earth entry for speeds greater than approximately 10 km/s and for many Mars entry conditions) and where further experimental data would be highly beneficial (e.g. lower speed Earth entry around 7.5 to 10 km/s and higher speed CO2 entries relevant to Venus). Nominal test conditions for both Earth and Mars are provided for future potential facilityto-facility comparisons.
Modulus prediction of buckypaper based on multi-fidelity analysis involving latent variables

Buckypapers are thin sheets produced from Carbon NanoTubes (CNTs) that effectively transfer the exceptional mechanical properties of CNTs to bulk materials. To accomplish a sensible tradeoff between effectiveness and efficiency in predicting the mechanical properties of CNT buckypapers, a multi-fidelity analysis appears necessary, combining costly but high-fidelity physical experiment outputs with affordable but low-fidelity Finite Element Analysis (FEA)-based simulation responses. Unlike the existing multi-fidelity analysis reported in the literature, not all of the input variables in the FEA simulation code are observable in the physical experiments; the unobservable ones are the latent variables in our multi-fidelity analysis. This article presents a formulation for multi-fidelity analysis problems involving latent variables and further develops a solution procedure based on nonlinear optimization. In a broad sense, this latent variable-involved multi-fidelity analysis falls under the category of non-isometric matching problems. The performance of the proposed method is compared with both a single-fidelity analysis and the existing multi-fidelity analysis without considering latent variables, and the superiority of the new method is demonstrated, especially when we perform extrapolation.

When analyzed the researches, this research will be original, and it will provide significant contributions to the literature. This research aims to explore the factors affecting the techno-pedagogical competencies and critical thinking skills of preservice mathematics teachers and to reveal the relation between their critical thinking skills and techno-pedagogical competencies. At that point, this research is remarkable for presenting an idea about raising more qualified mathematics teachers. This study was designed as descriptive study. The research group of this study hosts a total of 552 preservice elementary mathematics teachers. The research has employed two data collection tools: "TPACK Self-Efficacy Scale" and "Critical Thinking Scale". The research data were analyzed by using Statistical Package for Social Science (SPSS) 21.0. The research results reveal that the technopedagogical skills and critical thinking abilities of preservice mathematics teachers are midlevel. On the other hand, there is a significant relation between the preservice mathematics teachers’ critical thinking abilities and technopedagogical competencies.
Investigations into the effect of gamma irradiation on the leakage current of 130-nm readout chips for the ATLAS ITk strip detector

Central to the design of any detector system is a detailed understanding of the current and power dissipation due to the implications on power-supply design, thermal management and mechanical stability. It is well documented that certain 130-nm CMOS technologies exhibit an increase in the leakage current when exposed to ionising radiation. Such 130-nm technology is employed in the readout ASICs of the ATLAS ITk Strip Tracker Upgrade. Using the so-called ABC130 prototype chipset, measurements are presented which allow the parametrisation of the increase in current as a function of dose rate in the region of phase space most applicable to High-Luminosity LHC conditions. Studies investigating the batch-by-batch, chip-by-chip and wafer-by-wafer variation of the total current increase are presented which demonstrate a significant batch-by-batch variation alongside non-negligible variations within wafers. Furthermore, studies are shown investigating the long-term annealing of irradiated chips (up to four months storing chips at 80 C). Finally, the feasibility of pre-irradiating wafers to mitigate the current increase is demonstrated.
