The parasitoid species complex associated with sexual and parthenogenetic Naryciinae (Lepidoptera: Psychidae): Integrating ecological and molecular analyses

This study describes the parasitoid species complex associated with seven closely related species of sexual (Siederia rupi- collella, S. listerella, Dahlica lazuri, D. charlottae and D. lichenella) and parthenogenetic (Dahlica fennicella and D. triquetrella) Naryciinae (Lepidoptera: Psychidae) in Central Finland. A thorough ecological analysis of all the species of parasitoids recorded was combined with analyses of molecular data. Mitochondrial and nuclear DNA data were obtained from all the species in order to (1) detect cryptic species associated with host specialization, (2) assign undescribed males to females, and (3) verify the morphological identification of closely related species. A DNA barcoding technique was employed to identify host species from parasitized larval remains. By sampling more than 10,000 host larvae, of which 25.7% were parasitized, nine parasitoid species were identified mor- phologically, including both koinobionts (Ichneumonidae: Diadegma incompletum, Macrus parvulus, Trachyarus borealis, T. solya- nikovi, T. fuscipes, T. brevipennis and Braconidae: Meteorus affinis) and idiobionts (Ichneumonidae: Orthizema flavicorne, Gelis fuscicornis). Ecological characteristics such as time and mode of host attack, time of emergence and level of specialization differed widely. The results show that differences in parasitoid biology need to be taken into account when studying differences in percentage parasitism of sexual and parthenogenetic Naryciinae. The molecular data revealed that one parasitoid species M. parvulus may con- sist of two cryptic forms associated with the sexual and parthenogenetic hosts, respectively. The data further establishes that T. bre- vipennis and some T. fuscipes are in fact morphotypes of one species. The large variation in mitochondrial DNA within species and its inconsistency with nuclear DNA demonstrate that current species and genus delimitation is inadequate in the Trachyarus species group. Our study shows that it is essential to use DNA barcoding methods when investigating host-parasitoid complexes.
CIRJE-F-567 A New Scheme for Static Hedging of European Derivatives under Stochastic Volatility Models

This paper proposes a new scheme for static hedging of European path-independent derivatives under stochastic volatility models. First, we show that pricing European path-independent derivatives under stochastic volatility models is transformed to pricing those under one-factor local volatility models. Next, applying an efficient static replication method for one-dimensional price processes developed by Takahashi and Yamazaki[2007], we present a static hedging scheme for European path-independent derivatives. Finally, a numerical example comparing our method with a dynamic hedging method under the Heston[1993]’s stochastic volatility model is used to demonstrate that our hedging scheme is effective in practice.
Anaphoric pronouns for topic devices: theoretical claims and acquisitional evidence.

West-European languages use articles to distinguish arguments as . Besides articles there are personal pronouns that are to be indexed with a discourse antecedent. Superimposed on that system there are additional devices to indicate whether a clause has the same or a different element as its topic. If a sentence takes a topic different from the topic of the preceding sentence, there are devices with enhanced saliency to mark the sentence as . These devices vary with the type of language. The present paper will characterize the anaphoric pronouns in Germanic and Romance languages and range them upon a saliency scale. This will bring about a new analysis of the accessibility hierarchy for the antecedent. Subsequently, I will discuss the acquisition of anaphoric pronouns for in Germanic (V2nd) Dutch and Romance French. The data come from a longitudinal study of two CHILDES corpora.
What Motivates Chinese Sports Fans to Subscribe to Athletes' Social Networking Service Accounts?

This study attempted to identify the motivational factors for using athletes’ SNS among Chinese sports fans. The researchers posted a hyperlink of an online survey on a total of 8 Chinese Olympians’ SNS(Weibo) accounts after obtaining the athlete’s approval. A total of 274 surveys were gathered from the visitors of SNS. Of the 274 surveys, 33 were discarded because of missing values. Confirmatory factor analysis and structural equation modeling revealed the following. Diversion, pass-time, athlete support, and technical knowledge were significantly and positively related to social media consumption while information, socialization, and fanship had no significant predictive effect on social media consumption
Effect of Defoliation on Growth and Yield Response in Two Tomato (Solanum lycopersicum Mill.) Varieties

An experiment was conducted at Plant Physiology laboratory of Bangladesh Institute of Nuclear Agriculture, Mymensingh, Bangladesh to investigate the effect of defoliations on crop characters, yield attributes and yield of two tomato varieties. The experiment comprised five levels of defoliation viz., 0 (control), 3, 6, 9 and 12 leaves defoliation out of 16 leaves and two varieties viz., Binatomato-4 and Binatomato-5. The experiment was laid out in two factors completely randomized design with four replications. Results revealed that defoliation and variety had significant effect on the studied crop characters and yield except the number of effective flower clusters per plant and fruit yield for variety. Most of the parameters like plant height, number of branches and leaves per plant, straw weight per plant, number of effective and non effective flower cluster per plant, number of flowers and fruits per plant, individual fruit weight and fruit yield per plant increased with defoliations over control up to 6 leaves and produced the highest in 3 leaves defoliated plant whereas the lowest was obtained in 12 leaves defoliated plants followed by 9 leaves defoliated plants. Therefore, due to the performance of morphological and yield attributing traits especially number of fruits per plant and number of fruits per cluster were superior in Binatomato-5 but fruit yield was inferior compared to Binatomato-4 in respect of smaller fruit size.
The relationship between ethnicity, Christian orthodoxy, and mental health

Although researchers have noted differences in the role of religiosity in the lives of people from different ethnic backgrounds, the components of religion's influence (i.e., membership and orthodoxy) on mental health have not been previously examined. In the current study, Christian participants’ Christian Orthodox Scale (COS) scores were used to predict scores on mental health. As hypothesized, African Americans with higher COS scores exhibited fewer mental-health problems than did all ethnicities studied with lower COS scores. Implications and future directions for understanding the cultural influence of religion on African Americans are discussed.
A LOW POWER 2.5 V, 5-BIT, 555-MHZ FLASH ADC IN 0.25 DIGITAL CMOS

This paper is devoted to the design and implementation of high speed, low power, low voltage flash analog to-digital convertors (ADC). A 5-bit flash ADC, with a maximum acquisition speed of 555 MHz, is implemented in a 2.5 V analog supply voltage. To achieve high speed in featured analog to digital converter utilizes Threshold inverter Quantization technique. A 5-bit CMOS Flash ADC was designed with 0.250 µm CMOS technology. It operates with speed of 555 MSPS while dissipating power of 11.58 mW at 2.5V. The key idea of this technique is to generate 2 n – 1 different sized threshold inverter quantization comparators for an n-bit converter due to which the fast data conversion speed improves the operating speed and the elimination of ladder resistors leads significant reduction in the power consumption. The use of two cascaded inverters as a voltage comparator is the reason for the technique's name (TIQ). The gain boosters make sharper thresholds for comparator outputs and provide a full digital output voltage swing. The comparator outputs - the thermometer code - are converted to a binary code in two steps through the `01' generator and the encoder. The proposed 5-bit flash ADC using TIQ is designed using FAT tree encoder and simulated with the help of TANNER-EDA tool in 0.25 µm CMOS technology . The proposed ADC is suitable for System-on-Chip (SoC) applications.
Measurement and characterization of dual-band LoRa communication in the Antarctic

The Antarctic is vast continent without any communication or power infrastructure. However, many countries operate scientific experiments in the Antarctic and desire lowpower long-range data communication for their scientific measurement setups. Currently, expensive satellite communication via Argos or Inmarsat is often employed. In case of limited data rate, sub-GHz frequency bands offer excellent radio wave propagation to provide ground-based communication links. The longer wavelength in these bands results in less path loss for a similar range, compared to microwave links at GHz frequencies. In a recent evolution, LoRa networks are deployed, allowing a larger link budget thanks to chirp spread spectrum modulation. In this paper, a number of dual band mobile-to-base-station measurements are described for the 434 and 868 MHz frequency bands. The channel measurements are analyzed for signal to noise ratio and packet loss, as recorded for different practical trajectories. The relation between packet loss and signal to noise ratio is also provided for practical applications in mobile to base station communication links.
15 Derivation and Innovation in Improper Geology, aka Geomorphology

Geomorphologists have contributed to geological understanding in several ways. First, the form of the land surface provides an introduction to various geological phenomena and the first indications of subsurface structure and events, past, present and future. Second, knowledge of contemporary processes, to which geomorphologists have contributed, facilitates the interpretation of palaeosurfaces, of past deposits and of past events. Third, the land surface is part of the record of earth history, which is the core and focus of geology. Over considerable areas of each of the continents morphology provides the only clues to Phanerozoic events. Fourth, geomorphological concepts are of considerable practical or applied significance, for example in the search for minerals, in engineering geology and in planning generally. Yet geomorphology has lost and continues to lose status in the geological profession, both academic and non-academic (governmental, industrial). Some geologists regard geomorphology as not proper or not real geology. The possible reasons for this are broached and responses discussed. The feasibility of geomorphology severing its ties with geography and geology and 'going it alone' is considered. Though attractive in principle the move is regretfully rejected as impractical. The loss of the geological link is also seen as deleterious, for geomorphology is basically chronological. Geomorphology has been particularly hard hit by recent educational and research trends, and by the shortage of job openings which utilise geomorphological education. The best hope for the future of geomorphology lies in a general return to and acceptance of curiosity-driven education, learning and research, together with success in convincing our geological colleagues of the rigour, value and relevance of our discipline.

Research on the Strength Variation of Root-Clay Systems under Freeze-Thaw Action

The aim of this paper is to study the influence of an effective root system of rhizome plants on the reinforcement of slope soil under freeze-thaw conditions. This study focused on the mechanical properties between roots and clay in the root system of four plant species from different regions of China (northeast, northern, central, and southern areas): Setaria viridis, Eleusine indica, Zoysia japonica, and Carex leucochlora. Based on the interfacial friction effects between the plant roots and the soil, pull-out tests and unconfined compressive strength tests were conducted on the reinforced soil system for varying numbers of freeze-thaw cycles. Several stages of the pull-out process of the root system in clay are explicitly proposed based on the interfacial friction test results. The results showed that the friction effect between Zoysia japonica roots and the soil was the most significant and that these roots had the best reinforcement effect. In contrast, the friction and reinforcement effects between Setaria viridis roots and the soil were the worst, and the resulting unconfined compressive strength was the smallest. However, the freeze-thaw resistance ability of the Setaria viridis and soil system was stronger than that of the Zoysia japonica system.
Semantic-based Distributed Version Control Model

Aiming at drawbacks of the poor universality of traditional version control model, a semantic model which can organize unstructured data into structured data is discussed in this paper. Using semantic model can describe the change process of design object dynamically;then this paper further proposed a model called SDVCM (semantic-based distributed version control model) to realize distribute version control. The contrast experiment proved that SDVCM is obviously superior to the existing version model in time and space overhead.
Developing critical embedded systems on multicore architectures: the Prelude-SchedMCore toolset

In this paper we present an end-to-end framework for the design and the implementation of embedded systems on a symmetric multicore. The developer first specifies the system using the \prelude language, a formal real-time architecture description language. The Prelude compiler then translates the program into a set of communicating periodic tasks that preserves the semantics of the original program. The schedulability analysis is performed by the SchedMCore analyzer. If the program is schedulable, it can finally be executed on the target multicore architecture using the \schedmcore execution environment.
Dike propagation through layered rocks

[1] Dike penetration through a succession of upper crustal layers with different densities is studied with a new numerical code. For an individual layer to significantly affect dike ascent, its thickness must be of order 1 when scaled to the characteristic length-scale for the inflated nose region that develops below the dike tip. This characteristic length is L* ∝ (μQ)1/6 (G/(1 − ν))1/2 (Δρg)−2/3, where μ and Δρ are the viscosity and buoyancy of magma, G and ν are elastic moduli for the encasing rocks, Q is the magma flow rate and g gravity. For basaltic dikes, L* is ≈1 km, which is of the same order of magnitude as the typical thickness of sedimentary strata and volcanic deposits. In such conditions, dike ascent proceeds irregularly, with large changes of velocity and width at an interface. Scaling laws for the ascent rate and dike width are derived. Penetration through low-density layers is determined by a local buoyancy balance in the inflated nose region of the dike, independently of the total buoyancy of the magma column between source and tip. In such conditions, a dike develops an internal overpressure that may be large enough to generate a horizontally propagating sill. For this to occur, the thickness of the low-density layers must exceed a threshold value, which depends only on the rock strength and on the average negative buoyancy of magma. For basaltic melt, we estimate that this threshold thickness cannot be less than about 700 m and is 2 km on average.
BIG BANG-BIG CRUNCH ALGORITHM FOR MINIMIZING POWER CONSUMPTION BY EMBEDDED SYSTEMS

The paper presents a nature inspired algorithm that copies the big bang theory of evolution. This algorithm is simple with regard to number of parameters. Embedded systems are powered by batteries and enhancing the operating time of the battery by reducing the power consumption is vital. Embedded systems consume power while accessing the memory during their operation. An efficient method for power management is proposed in this work. The proposed method, reduce the energy consumption in memories from 76% up to 98% as compared to other methods reported in the literature.
Inverse Equivalent Surface Current Method with Hierarchical Higher Order Basis Functions, Full Probe Correction and Multilevel Fast Multipole Acceleration (Invited Paper)

An inverse equivalent surface current method working with equivalent electric and/or magnetic surface current densities on appropriately chosen Huygens surfaces is investigated. The considered model with triangular surface meshes is compatible with the models known from method of moments (MoM) solutions of surface integral equations. Divergence conforming current basis functions of order 0.5 and of order 1.5 are considered, where the order 0.5 functions are the well-known Rao-Wilton-Glisson basis functions. Known near-fleld samples typically obtained from measurements are mapped on the unknown equivalent surface current densities utilizing the radiation integrals of the currents as forward operator, where the measurement probe in∞uence is formulated in a MoM like weighting integral. The evaluation of the forward operator is accelerated by adaptation of the multilevel fast multipole method (MLFMM) to the inverse formulation, where the MLFMM representation is the key to full probe correction by employing only the far-fleld patterns of the measurement probe antennas. The resulting fully probe corrected algorithm is very ∞exible and e-cient, where it is found that the computation speed is mostly dependent on the MLFMM conflguration of the problem and not that much on the particular equivalent current expansion as long as the expansion is able to represent the currents su-ciently well. Inverse current and far-fleld pattern results are shown for a variety of problems, where near-fleld samples obtained from simulations as well as from realistic measurements are considered.
Efficacy of GLP-1 Infusion in Congestive Heart Failure Patients on Myocardial Function

Background: Congestive heart failure (CHF) and diabetes mellitus are serious and chronic complex diseases that commonly coexist together. The pathophysiology of the link between congestive heart failure and diabetes is impaired glucose homeostasis that affects the myocardium at both the cellular and structural level that eventually affects its intrinsic biochemical pathway leading to progression of the failing heart. The aim of this study was to attempt to clarify whether glucagon-like peptide (GLP-1) infusions improve cardiac function in congestive heart failure patients. Methods: An exhaustive search of Medline-OVID, CINAHL, Medline-PubMed and Google Scholar using the keywords: congestive heart failure, insulin resistance, diabetes, metabolism, GLP-1, exenatide, liraglutide, and left ventricular function. Relevant articles were assessed for quality using GRADE. Results: Three studies met inclusion criteria and were included in this systematic review. A non-randomized pilot study of 21 CHF patients with and without diabetes with 5 weeks of GLP-1 infusion that demonstrated improved left ventricular ejection fraction (LVEF) and quality of life (QOL). A double-blind, randomized, two-period cross-over trial of 20 CHF patients with diabetes with 6 hours of GLP-1 infusion followed by a wash out period illustrated improved cardiac function (cardiac index, PCWP, RAP). The final study was a non-randomized pilot study of 6 patients with diabetes with 3 days of GLP-1 infusion that showed improved global systolic and diastolic function. Conclusion: The above clinical studies have provided a promising impact in the improvement of cardiac function in a failing heart. However, these studies lack randomization and are of a small sample size. Therefore, further intense research studies are necessary to confirm these initial observations and to investigate the underlying mechanisms and explore possible interactions with the current heart failure therapies. At this point, the role of GLP-1 in reversing the cardiac function in the failing heart are still at its infancy, thus more clinical trials with stronger patient important outcomes in regards to cardiovascular morbidity and mortality as needed
Ethics, Information Technology, and Today's Undergraduate Classroom

This paper highlights interdisciplinary research grounding a course that is one of the core requirements of a new undergraduate informatics curriculum. Ethics and Information Technology explores the ethical dilemmas that exist where human beings, information objects, and information systems interact. The course tests the notion that the most effective way to explore how new technologies relate to integrity, truthfulness, trust, respect for privacy and individuality is to become immersed in a technological environment where unethical behavior as well as ethical norms can be safely and confidentially tested, evaluated, observed, and experienced. The paper will summarize an emerging literature in three areas: (1) the theories of ethics and information technology, (2) the characteristics of the “Net Generation” regarding the use of new technologies, and (3) the central role played by “trust” in assessing the ethical implications of new technologies, including online multiplayer games, image editing, collaborative authoring, and open source coding conventions. The paper will then demonstrate how this literature informs the design and implementation of the course.
Consumers online: intentions, orientations and segmentation

Purpose – The purpose of this paper is to examine the purchase intentions of online retail consumers, segmented by their purchase orientation.Design/methodology/approach – An e‐mail/web survey was addressed to a consumer panel concerning their online shopping experiences and motivations, n=396.Findings – It is empirically shown that consumer purchase orientations have no significant effect on their propensity to shop online. This contradicts the pervasive view that internet consumers are principally motivated by convenience. It was found that aspects that do have a significant effect on purchase intention are prior purchase and gender.Research limitations/implications – There are two limitations. First, the sample contained only UK internet users, thus generalisations about the entire population of internet users may be questionable. Second, in our measurement of purchase intentions, we did not measure purchase intent per se.Practical implications – These findings indicate that consumer purchase orientati.
