VNM: An R package for finding multiple-objective optimal designs for the 4-parameter logistic model

A multiple-objective optimal design is useful for dose-response studies because it can incorporate several objectives at the design stage. Objectives can be of varying interests and a properly constructed multiple-objective optimal design can provide user-specified efficiencies, delivering higher efficiencies for the more important objectives. In this work, we introduce the VNM package written in R for finding 3-objective locally optimal designs for the 4-parameter logistic (4PL) model widely used in education, bioscience and in the manufacturing industry. The package implements the methodology to construct multipleobjective optimal designs in Hyun and Wong (2015). As illustrative examples, we focus on a biomedical application where our objectives are to estimate: (1) the shape of the dose-response curve, (2) the median effective dose level (ED50) and (3) the minimum effective dose level (MED) in the 4PL model. Our VNM package uses a state-of-theart algorithm to generate multiple-objective optimal designs that meet the user-specified efficiency requirement for each objective, provides tools for calculating the efficiency of the generated design under each objective and also a plot for confirming optimality of the VNM-generated design. The package can also be used to determine an optimal scheme for allocating subjects to the various doses when the number and doses of the drug are fixed in advance.
, Denmark June 11-13 , 2018 Human Capital Sorting into New Firms

Human capital features prominently in theoretical work on post-entry performance of new firms. Empirical analysis has, however, to a large extent overlooked the unobserved component of human capital focusing on years of education or labor market experience. This paper adds to the literature on human capital and post-entry performance by putting the unobserved dimension of human capital in the center of the analysis. I find strong evidence that workers sort into new firms on unobserved skills. The results confirm that on average employees in new firms are less skilled relative to those employed by incumbents. Firm-level duration analysis reveals that sorting is important, as new businesses that employ workers with greater unobserved skills are found to enjoy lower probability of exit, even after controlling for workers' education.

ON THE GENUS DICTYOTA ( DICTYOTACEAE , PHAEOPHYCEAE ) IN THE PERSIAN GULF , IRAN

In this research, the taxonomic status of the genus Dictyota in southern coastlines of Iran was studied. Taxonomy of the genus at species levels is complicated and difficult due to the high morphological plasticity in response to environmental conditions and overlapping of diagnostic characters. In this study, we combined morphological information with cytoplasmic barcoding data from DNA rbcL and psbA. We identified Dictyota acutiloba as new record and also confirmed the presence of Dictyota ciliolata in the Persian Gulf and Gulf of Oman. Our studies showed D. ciliolata species has high inter-specific morphological diversity.

Large Scale Evolving Graphs with Burst Detection

Analyzing large-scale evolving graphs are crucial for understanding the dynamic and evolutionary nature of social networks. Most existing works focus on discovering repeated and consistent temporal patterns, however, such patterns cannot fully explain the complexity observed in dynamic networks. For example, in recommendation scenarios, users sometimes purchase products on a whim during a window shopping.Thus, in this paper, we design and implement a novel framework called BurstGraph which can capture both recurrent and consistent patterns, and especially unexpected bursty network changes. The performance of the proposed algorithm is demonstrated on both a simulated dataset and a world-leading E-Commerce company dataset, showing that they are able to discriminate recurrent events from extremely bursty events in terms of action propensity.
Synthesis, characterization and antibacterial activity of cobalt doped cerium oxide (CeO 2 :Co) nanoparticles by using hydrothermal method

Different concentrations (2, 4, 6, and 8 mole %) of cobalt doped cerium oxide nanoparticles (CeO2:Co NPs) were synthesized by hydrothermal method. The synthesized samples were characterized by using various techniques to understand their structural, optical and surface morphological properties. The face-centred cubic (FCC) structure of the CeO2:Co NPs was identified from the X-ray diffraction (XRD) analysis. The calculated crystallites size of the CeO2:Co NPs were decreased from 20 nm to 17 nm on increased the concentration of cobalt from 2 mole % to 8 mole %. The bonding formation between cerium and oxygen (Ce O) was confirmed using Fourier transform infra-red spectroscopy (FTIR). The surface morphology and shape of the CeO2:Co NPs were examined by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The SEM images have revealed a cube shaped, uniformly distributed and well dispersed CeO2:Co NPs. Further, a slight distortion of surface morphology was obtained when increased the concentration of cobalt. The optical properties were investigated by using ultra-violet visible (UV–vis) spectroscopy. A optical absorption band nature was observed from CeO2:Co NPs when compared with bulk spectrum. The bandgap energy of the CeO2:Co NPs were increased from 3.64 eV to 3.69 eV on increased the cobalt concentration. The photoluminescence (PL) emission spectrum of CeO2:Co NPs showed an enhanced defect of reduced emission by using spectrofluorometer. The CeO2:Co NPs resulted good antibacterial activity against pathogenic bacteria such Escherichia coli, Staphylococcus aureus, Bacillus Cereus and Salmonella Typhi. Hence, the CeO2:Co NPs could be used as biomaterial in nano-biotechnology applications. © 2018 Published by Elsevier Editora Ltda. on behalf of Brazilian Metallurgical, Materials and Mining Association.

R eview of Web Personalization

Today the modern phase of the internet is the personalize phase where the user is able to view everything that matches his/her interest and needs. Nowadays, Web users are relying totally on the internet in relation to all the problems they have in their daily life. If someone wants to find a job he/she will look on the internet, similarly if someone wants to buy some product/item the best preferred platform will be the internet so due to large numbers of users on the internet and also due to the large amount of data on the internet people starts preferring those platforms where they can find what they need in as minimum time as possible. The only way to make the web intelligent is through personalization. Web Personalization has been introduced more than a decade ago and many researchers have contributed to make this strategy as efficient as possible and also as convenient for the user as possible. Web personalization research has a combination of many other areas that are linked with it and includes AI, Machine Learning, Data Mining and natural language processing. This report describes the whole era of web personalization with a description of all the processes that have made this technique more popular and widespread. This report has also thrown light on the importance of this strategy and also the benefits and limitations of the methods that are introduced in this strategy. This report also discusses how this approach has made the internet world more facilitating and easy-to-use for the user.

Feature-based fast grasping for unknown objects

According to the report by the United Nations in 2015, the global population of older persons aged 60 years or over is predicted to grow to 1.4 billion by 2030. A rapidly aging population poses a challenging problem for human beings, i.e. supply shortage of working-age people. To solve this problem, increasing research efforts are poured into the field of robotics, especially in service robotics. Service robots are believed to be a solid solution to the challenging problem of an aging population. The Strategic Research Agenda (SRA) for Robotics in Europe, a development guideline for European robotics from 2014 to 2020, classifies robots’ functions into eight basic categories, i.e., assembly, surface process, interaction, exploration, transporting, inspection, grasping and manipulation. From SRA, we can find that grasping is an important basic function for robots. Combining grasping with other basic functions, robots can perform many service tasks to free humans from tedious housework, for example, cleaning rooms, cooking and washing dishes.
CONCEITUAIS E PRÁTICOS EMOTION , EMOTIONAL REGULATION AND BEHAVIOR : HISTORICAL , CONCEPTUAL AND PRACTICAL ASPECTS

In a behavioral perspective, emotions are private events and must be characterized as predispositions of an organism for action. Such preprogrammed actions were acquired throughout the evolutionary history of the species, that is, a phylogenetic heritage, but also, are under control of historical environmental variables resulting from the individual’s exposure to contingencies. People adopt strategies to regulate emotions, and the ability to do so composes a highly adaptive capacity in the human repertoire and occurs in situations in which emotional experience is judged as harmful. As a rule, the emotions that are the target of regulation are negative emotions and strategies are sought in order to influence the trajectory of emotion. The article deals with the definition of emotions and emotional regulation from the perspective of James Gross, presents cognitive and behavioral strategies for emotional regulation, and discusses the question of why people regulate emotions.
2 . 3 Detecting objects affordances with convolution neural networks [ 3 ]

Humans have a great capability to distinguish objects by their vision. But, for machines object detection is an issue. Thus, Neural Networks have been introduced in the field of computer science. Neural Networks are also called as ‘Artificial Neural Networks’ [13]. Artificial Neural Networks are computational models of the brain which helps in object detection and recognition. This paper describes and demonstrates the different types of Neural Networks such as ANN, KNN, FASTER R-CNN, 3D-CNN, RNN etc. with their accuracies. From the study of various research papers, the accuracies of different Neural Networks are discussed and compared and it can be concluded that in the given test cases, the ANN gives the best accuracy for the object detection.

INIAP-Estación Experimental Tropical Pichilingue materials

The use of plant biomass is a sustainable alternative to the reduction of CO2 emissions. Agricultural residues are interesting bioenergy feedstocks because they do not compete with food and add extra value to the crop, which might help to manage these residues in many regions. Breeding crops for dual production of food and bioenergy has been reported previously, but the ideal plant features are different when lignocellulosic residues are burnt for heat or electricity, or fermented for biofuel production. Stover moisture is one of the most important traits in the management of agricultural waste for bioenergy production which can be modified by genetic improvement. A delayed leaf senescence or the stay-green characteristic contributes to higher grain and biomass yield in standard, low nutrient, and drought-prone environments. In addition, the stay-green trait could be favorable for the development of dual purpose varieties because this trait could be associated with a reduction in biomass losses and lodging. On the other hand, the stay-green trait could be detrimental for the management of agricultural waste if it is associated with higher stover moisture at harvest, although this hypothesis has been insufficiently tested. In this paper, a review of traits relevant to the development of dual purpose varieties is presented with particular emphasis on stover moisture and stay-green, because less attention has been paid to these important traits in the literature. The possibility of developing new varieties for combined production is discussed from a breeding perspective.
Competitive Hold-Up: Monopoly Prices and the Response in Related Markets

Hold-up creates an unappreciated cost of monopoly even if the held-up side of the market is perfectly competitive. If a monopolist cannot commit to a wholesale price in advance, competitive retailers with U-shaped cost curves will be reluctant to enter, knowing that the monopolist has incentive to raise the price and reduce their quasi-rents. Forward-looking retailers will earn zero profits in the long run, but their caution hurts the monopolist by shifting in the short-run market supply of retailer services. A similar problem occurs if the monopolist’s product is sold directly to consumers but is a complement to a perfectly competitive good. Competitive hold-up arises from upstream opportunism, not downstream market power, and so is distinct from double marginalization and the two-monopoly complements externality.

AN INVESTIGATION OF THE INFLUENCES ON THE GEOCHEMISTRY OF STREAMS IN DOMINICA, LESSER ANTILLES: 2014-2017

The chemical makeup of stream waters is a reflection of the environment upstream. Two important tools in determining water provenance are stable isotopes (δO and δH) and major ion concentrations, both useful for determining environmental influences in tropical climates (Lachniet and Patterson, 2009, Goldsmith et al., 2010). Much is known about the relationships between environmental factors and stream chemistry in the temperate catchments of North America and Europe; however, little is known about tropical volcanic regions (McDowell et al., 1995, Johnson et al., 1997, ). This project will serve to give a general overview of the major environmental controls on stream stable isotope and major ion geochemistry in Dominica and, by extension, the surrounding Lesser Antilles considering multiple and potentially complex interactions of these factors. With a baseline knowledge of the current controls on chemistry, future changes to this baseline can be explored.

Photo induced three body decay by CHRISTOF MAUL ‹ and

The photo induced three body decay : ABC ­ h m ! A ­ B ­ C, where a molecule ABC decays into three fragments A, B and C upon irradiation, is reviewed. Various experimental and theoretical techniques for the investigation of this reaction and their application to a wide range of molecular species are discussed. Emphasis is laid on the distinction between concerted and stepwise processes, consisting of one single or two consecutive kinetic events, respectively. The concerted fragmentation scheme is further classi® ed as being of either synchronous or asynchronous character, depending on whether or not the bond breaking processes take place in unison. The three body decays of acetone, azomethane and s-tetrazine are discussed in detail as prototypes for these mechanisms. A novel kinematic analysis approach, based on the evaluation of fragment kinetic energy distributions, is presented and applied to the ultraviolet photodissociation of phosgene. Competing pathways are found to be operative, dominated by the asynchronous concerted mechanism with preferential forward scattering of the carbon monoxide fragment. The synchronous concerted decay plays a minor role under signi® cant excitation of the in-plane and out-of-plane bending modes of the parent molecule. Finally the power of the newly developed method for the analysis of the three body decay of a small polyatomic molecule is highlighted.
The Pennsylvania State University The Graduate School Eberly College of Science DENSITY PROPERTIES OF CERTAIN GROUP ACTIONS AND JOINING RIGIDITY OF SOME SMOOTH SINGULAR FLOWS

This dissertation investigates two problems in dynamical systems. One is about density properties for certain group actions. More precisely, let Y be a compact metric space, G be a group acting by transformations on Y . For any infinite subset A ⊂ Y , we study the density of gA for g ∈ G and quantitative density of the set ⋃ g∈Gn gA by the Hausdorff semimetric d . As an example, it is proven that for any integer n ≥ 2, > 0, any infinite subset A ⊂ T, there is a g ∈ SL(n,Z) such that gA is -dense. The other one is a joint work with Adam Kanigowski, on joining rigidity of von Neumann flows with one singularity. They are given by a smooth vector field X on T \ {a}, where X is not defined at a ∈ T. The phase space can be decomposed into a (topological disc) DX and an ergodic component EX = T \ DX . Let ωX be the 1-form associated to X . We show that if | ∫ EX1 dωX1| 6 = | ∫ EX2 dωX2 |, then the corresponding flows (vX1 t ) and (v X2 t ) are disjoint. Moreover, for every X there is a uniquely associated frequency α ∈ T and it follows that for a full measure set of α ∈ T the class of smooth time changes of (vXα t ) is joining rigid, i.e. every two smooth time changes are either cohomologous or disjoint. This gives a natural class of flows for which the answer to Problem 3 in [29] is positive.
AgriDrone-A Ubicomp Prototype for Precision Farming Med Matovu

Precision agriculture aims at providing ICT tools that allow farmers to micromanage and make detailed plans for the work to be done. Solutions have existed since the 1980s but have not found widespread adoption. With the rapid development of low-cost open-source drones and advances in camera technology the last couple of years, we propose a system for monitoring crop development by taking pictures and planning agricultural activities using drones that can be controlled beyond visual range using a standard web application. The system was evaluated in terms of its perceived usability and a comparative measure on the time it takes to cover an area by foot comparing with using drone captures. We found usability of our system to be high and calculated the coverage time of the drone to be 3 times faster than manual effort. This will allow the farmers to schedule activities in a more informed way, saving time first and resources. Author
Attitude Control of Satellite With Pulse-Width Pulse-Frequency ( PWPF ) Modulator Using Generalized Incremental Predictive Control

In this paper, we use generalized incremental predictive control (GIPC) to stabilize attitude of satellite. We compare Generalized Predictive Control (GPC) with GIPC algorithm and present that GIPC has better performance. The threeaxis attitude control systems are activated in pulse mode. Consequently, a modulation of the torque command is compelling in order to avoid high non-linear control action. This work considers the Pulse-Width Pulse-Frequency modulator (PWPF) is composed of a Schmitt trigger, a first order filter, and a feedback loop. PWPF modulator has several advantages over classical bang-bang controllers such as close to linear operation, high accuracy, and reduced propellant consumption.
