Description of mixed-mode dynamics within the Symplectic extension of the Interacting Vector Boson Model

In the algebraic Interacting Vector Boson Model (IVBM) it is assumed that the nuclear dynamics can be described by means of two types of vector “quasiparticles”, which are also characterized by another quantum number a “T spin” (an analogue to the F−spin). The non-compact symplectic group Sp(12, R) appears as the group of dynamical symmetry for the problem of two interacting vector bosons. The symplectic structure allows the change in the number of phonons, needed to build the collective states, that results in larger model spaces, which can accommodate the more complex structural effects as observed in the contemporary experiment. The applications of the IVBM are extended by exploiting three new subgroup chains in the reduction of Sp(12, R) to the physical angular momentum subgroup SO(3). The corresponding exactly solvable limiting cases are applied to achieve a description of complex nuclear collective spectra of even-even nuclei in the rare earth and actinide regions up to states of very high angular momentum. The first reduction that we exploit is one that extends the rotational limit of the number preserving version of the model; namely, Sp(12, R) ⊃ U(6) ⊃ U(2) ⊗ SU(3). Another limit of the symplectic IVBM, Sp(12, R) ⊃ Sp(2, R) ⊗ SO(6), contains in a natural way the 6-dimensional Davidson potential. In both of these cases, because collective modes can be mixed, we obtain successful descriptions of both positive and negative parity band configurations. The structure of band-head configurations, whose importance is established in the first two limits, is also examined in a third reduction, Sp(12, R) ⊃ Sp(4, R) ⊗ SO(3). The distributions of energies that are obtained in this limit with respect to the number of bosons that build each of the states with fixed angular momentum, enables one to distinguish typical collective vibrational and rotational spectra. This algebraic chain also provides important links between the subgroups of the other limits. The symplectic extension of the IVBM permits a richer classification of the states than its unitary version and is shown to be appropriate for a description of rather diverse nuclear spectra.
Life after Bushfire: Post-Traumatic Stress, Coping, Post-Traumatic Growth

Introduction Research suggests that post-traumatic stress (PTS) symptoms are common after the experience of bushfire. However, the ways in which individuals cope with, positively grow from, and find benefit in the adverse circumstances of bushfire in Australia has not been adequately explored. The main objective of this study is to assess the relationship between PTS, coping strategies and post-traumatic growth, in a sample of Australian community members affected by a bushfire event. Methods Sixty-five participants (mean age 40.66 years, SD=13.57), who had previously experienced a bushfire event in Australia, responded to an anonymous online survey. Results Results indicated that greater PTS was associated with the use of all coping strategies, as well as higher levels of post-traumatic growth. The use of coping strategies was associated with higher levels of post-traumatic growth. Hierarchical regression analyses found that post-traumatic growth and avoidant coping explained significant amounts of unique variance in PTS, whereas PTS and emotion-focussed coping explained significant amounts of unique variance in post-traumatic growth. Conclusion In communities that are seasonally threatened by bushfires, our findings suggest that not only are post-disaster stress reduction interventions required, but so too are preparedness programs that include strategies for promoting growth and positive adaptation. It is suggested further research should address implications for strength-based preparedness and recovery programs in bushfire prone areas.
Carrier Multiplication and Its Reduction by Photodoping in Colloidal InAs Quantum Dots

Carrier (exciton) multiplication in colloidal InAs/CdSe/ZnSe core−shell quantum dots (QDs) is investigated using terahertz time-domain spectroscopy, time-resolved transient absorption, and quasi-continuous wave excitation spectroscopy. For excitation by high-energy photons (∼2.7 times the band gap energy), highly efficient carrier multiplication (CM) results in the appearance of multi-excitons, amounting to ∼1.6 excitons per absorbed photon. Multi-exciton recombination occurs within tens of picoseconds via Auger-type processes. Photodoping (i.e., photoinjection of an exciton) of the QDs prior to excitation results in a reduction of the CM efficiency to ∼1.3. This exciton-induced reduction of CM efficiency can be explained by the twofold degeneracy of the lowest conduction band energy level. We discuss the implications of our findings for the potential application of InAs QDs as light absorbers in solar cells.
International Correlation Asymmetries: Frequent-But-Small and Infrequent-But-Large Equity Returns

We propose a novel regime-switching model to study correlation asymmetries in international equity markets. We decompose returns into frequent-but-small diffusion and infrequent-but-large jumps, and derive an estimation method for many countries. We find that correlations due to jumps, not diffusion, increase markedly in bad markets leading to correlation breaks during crises. Our model provides a better description of correlation asymmetries than GARCH, copula and stochastic volatilit ymodels. Good and bad regimes are persistent. Regime changes are detected rapidly and risk diversification allocations are improved. Asset allocation results in and out-of-sample are superior to other models including the 1/strategy.
Consumption taxation and redistribution: the role of housing wealth (Preliminary and incomplete)

An increase in consumption taxes reduces the purchasing power of existing wealth. Hence, it e¤ectively acts as a capital levy. However, this capital levy does not apply to housing wealth in the same manner as it applies to nancial wealth. Moreover, tax reforms inducing changes in the after-tax interest rate will a¤ect households di¤erently depending on whether most of their overall wealth is in the form of housing or nancial wealth. We use a dynastic model of household savings and labour supply to study the distributional implications of tax reforms that consist of eliminating capital income taxation and increasing consumption taxes In contrast to previous literature, we distinguish between nancial wealth and housing wealth. Our results suggest that the special role of housing wealth makes such tax reforms much more progressive than what one would expect based on a model with a nancial asset only.

Using quantile regression to extend an existing wind power forecasting system with probabilistic forecasts

For operational planning it is important to provide information about the situation-dependent uncertainty of a wind power forecast. Factors which influence the uncertainty of a wind power forecast include the predictability of the actual meteorological situation, the level of the predicted wind speed (due to the non-linearity of the power curve) and the forecast horizon. With respect to the predictability of the actual meteorological situation a number of explanatory variables are considered, some inspired by the literature.The article contains an overview of related work within the field. An existing wind power forecasting system (Zephyr/WPPT) is considered and it is shown how analysis of the forecast error can be used to build a model of the quantiles of the forecast error. Only explanatory variables or indices which are predictable are considered, whereby the model obtained can be used for providing situation-dependent information regarding the uncertainty. Finally, the article contains directions enabling the reader to replicate the methods and thereby extend other forecast systems with situation-dependent information on uncertainty.

Title : Re-assessing the vertical distribution of testate amoeba communities in surface

Testate amoeba-derived transfer functions are frequently used in peatland palaeohydrological studies and involve the development of training sets from surficial peats. However, within acrotelmic peats, considerable vertical variation in assemblage composition can occur, particularly along Sphagnum stems, which may limit the representation of the associated „contemporary‟ testate amoeba samples as analogues for the peatland surface. This paper presents contiguous testate amoeba assemblage data from nine monoliths collected from different peatland microforms (hummock, hollow, lawn) in three Sphagnum dominated ombrotrophic peatlands in Ontario and Quebec, eastern Canada. The aim is to: i) gain a greater understanding of the vertical distribution of xerophilous/hygrophilous taxa along Sphagnum stems; ii) determine the vertical extent of live/encysted taxa along this gradient; and iii) assess the significance of this distribution on surface sampling protocols. The results show that testate amoeba communities in the uppermost acrotelmic peat layers display considerable variability. This may reflect a complex interplay of abiotic and biotic controls, including moisture, temperature, light and other characteristics, food availability, and mineral particle availability for test construction. These findings underline the complexity of testate amoeba community structure and highlight the importance of analysing both living and dead Sphagnum stem sections when developing calibration sets.
PENSION FUNDS AND CAPITAL MARKET DEVELOPMENT : HOW MUCH BANG FOR THE BUCK ?

This paper studies the relation between institutional investors and capital market development by analyzing unique data on monthly asset-level portfolio allocations of Chilean pension funds between 1995 and 2005. Our results depict pension fund administrators as large and important institutional investors that tend to hold a large amount of bank deposits, government paper, and short-term assets, buy and hold assets in their portfolios without actively trading them, hold similar portfolios at the asset-class level, simultaneously buy and sell similar assets, and when trading follow momentum strategies. These patterns do not seem fully consistent with the initial expectations that pension funds would be a dynamic force helping to develop different parts of capital markets. The results do not seem to be fully determined by regulatory restrictions. Instead, the illiquidity of many domestic assets and the incentives pension fund managers face might be behind the patterns illustrated in this paper.

Reevaluating Argument Component Extraction in Low Resource Settings

Argument component extraction is a challenging and complex high-level semantic extraction task. As such, it is both expensive to annotate (meaning training data is limited and low-resource by nature), and hard for current-generation deep learning methods to model. In this paper, we reevaluate the performance of state-of-the-art approaches in both single- and multi-task learning settings using combinations of character-level, GloVe, ELMo, and BERT encodings using standard BiLSTM-CRF encoders. We use evaluation metrics that are more consistent with evaluation practice in named entity recognition to understand how well current baselines address this challenge and compare their performance to lower-level semantic tasks such as CoNLL named entity recognition. We find that performance utilizing various pre-trained representations and training methodologies often leaves a lot to be desired as it currently stands, and suggest future pathways for improvement.
Adoption of RTEP Production Technology Among Cassava-based Farming Households In Southwest Nigeria

One of the fundamental ways of improving agricultural productivity is through introduction and use of improved agricultural technologies. Root and Tuber Expansion Programme (RTEP) was one of the agricultural programmes in Nigeria. This study examined the adoption of RTEP production technology among cassava-ba sed farming households in Southwest, Nigeria. The study utilized primary data collected using structured questionnaire. Multistage sampling technique was employed in the selection of 180 cassava-based farming households in four RTEP participating local government areas in the zone. The data were analyzed using descriptive statistics such as: frequency, mean, percentages, standard deviation and tables. The adoption level of RTEP improved cassava production technology by the RTEP farmers was 76% and adoption level of the technology differs by socio- economic characteristics. Level of adoption differs by educational level, participation in off-farm ac tivities and credit accessibility among other factors. Therefore, effective extension services should be put in place to give some level of training to farmers. Policy measures should be oriented towards the support and improvement of rural off- farm income opportunities and improving credit access should be considered as a core component of any development intervention such as RTEP.

Impacts of online banner advertisement on consumers' purchase intention: A theoretical framework

Virtual discussion between students and lecturers nowadays become easier and effective by using computer-mediated communication (CMC) tools.The issue on geographical distance is no longer a problem but there are some aspects that need attention, such as the consultation documentation, record log and the ability to see the records of these virtual relationships.Most current virtual communications software is focused on the communication and less on the process of before and after the virtual communication. In order to enhance the virtual communication process, we have designed and developed an Online Instructional Consultation (OICon) model to facilitate student-lecturer consultation for higher education mentor-mentee system in Malaysia.The model consists of 5 interrelated domains that are personalization, consultation processes and task involved, features and multimedia components, consultation content and consultation document.It provides alternative means on delivery of the contents and services as well as provides participants a range of option. By this way, students and lecturer can involve actively through online consultation at remote places, not just between lecturer and students but also on post-session discussion among peers.Point of correspondence includes implementation of CMC tools to facilitate online consultation processes for academic advisory purpose. OICon model was then transformed into a prototype system to verify the model. Based on the evaluation conducted, we found that users are relatively positive towards implementation of multimedia communication tools for consultation in higher education and they agreed that the OICon model is crucial for enhance and promote interactivity for consultation among students and lecturers.
Aspects of the Life Histories of Pinkrose Rockfish (Sebastes simulator) and Swordspine Rockfish (Sebastes ensifer) with Notes on the Subgenus Sebastomus

The rockfishes, genus Sebastes, form an extremely speciose group that often dominates the fish assemblages of California reefs between depths of 30 and 300 m (Love et al. 2002). The genus is divided into a number of subgenera (estimated at between 13 and 15, Hyde and Vetter 2007) among which the subgenus Sebastomus is particularly well characterized by congruencies in both morphology and genetics (Chen 1971; Rochas-Olivares et al. 1999; Hyde and Vetter 2007). In general, species in this subgenus are relatively small (to a maximum of 56 cm total length) (Table 1) and all are benthic or epibenthic (Love 2011). In addition, with the exception of Sebastes helvomaculatus, all of the North American species are relatively warm-water, and most are rare or absent from waters north of central California (Table 1). The basic biology and ecology of most of the Sebastomus living in the northeastern Pacific (i.e., with ranges extending at least into California waters) have been fairly well documented (summarized in Love et al. 2002; Love 2011; Fields 2016). The main exception was Sebastes simulator, the pinkrose rockfish, and to a lesser extent, Sebastes ensifer, the swordspine rockfish, whose life histories, were poorly understood. In this paper, we report on a number of aspects on the biology of S. simulator, provide supplementary data on the biology of Sebastes ensifer, and update basic information on all species in the subgenus Sebastomus. We collected specimens by hook-and-line from southern California waters (primarily from the northern Channel Islands), immediately placed them on ice aboard a research vessel, and then froze them in the lab for later examination. All specimens were measured [standard (SL), fork (FL), and total (TL) length] to the nearest millimeter and most were weighed (to the nearest 0.1 g). All lengths are reported as TL. We used sagittal otoliths for age determinations; these were removed and stored dry in coin envelopes. For age determinations, each otolith was glued to a wooden block, placed on a Bueller Isomet low-speed saw and a 0.05-cm wafer was cut from it, using two diamond-edge blades separated by a stainless-steel shim. Before reading, the wafers were slightly burned over an alcohol lamp. The wafers were then placed in a water-filled, blackbottomed watch glass and examined under a dissecting microscope. All wafers were read twice by M. Love. When reading did not agree, the otoliths were read again. The value of two coincident readings was accepted as the best estimate of age. We judged that the otoliths of about 5% of the specimens were unreadable due to poorly developed annuli. Lengths at ages were estimated by direct observation of otolith annuli and by using the von Bertalanffy growth model:
Enhancing Reversible Data hiding Schemes for Marked Covers

In reversible data hiding (RDH), the original cover can be losslessly restored after the embedded information is extracted. Kalker and Willems established a rate–distortion model for RDH, in which they proved out the rate–distortion bound and proposed a recursive code construction. In our previous paper, we improved the recursive construction to approach the rate–distortion bound. In this paper, we generalize the method in our previous paper using a decompression algorithm as the coding scheme for embedding data and prove that the generalized codes can reach the rate–distortion bound as long as the compression algorithm reaches entropy. By the proposed binary codes, we improve three RDH schemes that use binary feature sequence as covers, i.e., an RS scheme for spatial images, one scheme for JPEG images, and a pattern substitution scheme for binary images. The experimental results show that the novel codes can significantly reduce the embedding distortion. Furthermore, by modifying the histogram shift (HS) manner, we also apply this coding method to one scheme that uses HS, showing that the proposed codes can be also exploited to improve integer-operation-based schemes.
PLC Based Automatic Intelligent Car Parking System

The main purpose of this paper was to design and implement an intelligent car parking system. The proposed system works on three modes such as ON, OFF and EMERGENCY. The system developed is able to sense the presence of the vehicles standing at the main car parking gate through an IR sensor. These IR sensors give their output to the PLC (programmable logic controller). Due to lack of parking spaces and skilled labour, there is a global shift towards the automatic car parking system to calculate accurate space available for car and revenue collection as a parking fee. This new scheme provides an improvement and reliability in the current car parking system and this system can be implemented easily because it is very economical as it uses solar panel for its power consumption and also the cheap IR sensor reduces the implementation cost.
HERITABILITY AND RESPONSE TO SELECTION FOR GROWTH IN THE F1 GENERATION OF CRAYFISH Procambarus acanthophorus

The crayfish Procambarus (A.) acanthophorus is a crustacean relevant for regional fisheries in Veracruz, Mexico, with ideal aquaculture characteristics, except for its small size. Thus, a study was conducted with the aim to evaluate the response to selection in the first generation (F1) and heritability (h2) of the crayfish. A group of 2135 organisms with average weight (Â±S.D.) 4.1 Â± 1.79 g were captured from the wild (G0), and 10 % (i = 1,755) of the population was selected with the highest body weight by gender: 140 females (5.62 Â± 1.97 g) and 48 males (6.02 Â± 1.9 g), forming the progenitors of the selection line (LS). The control line (LC) was formed from a batch obtained at random. Thirty full-sib families were obtained per line (F1), and cultured individually for five months in a recirculation system with mechanical and biological filtration under laboratory conditions and supplied with food twice a day (Camaronina 35 % protein). Monthly heritability (h2) in broad sense was estimated using a full-sib design, based on the components of variance (ANOVA REML method) and the growth was compared between lines in the F1. The mean h2's for weight after five months of culture were 0. 27Â±0.11 for LC and 0. 34Â±0.12 for LS, being the LS in F1 9.6 % heavier than the LC, with 84 and 88 % survival at the end of the study. It is possible to implement a breeding program based on selection for species growth.
EFFECTIVENESS OF CLASSIC VERSIONS OF OPTIONS PRICING MODELS IN RECENT WAVES OF FINANCIAL UPHEAVALS

This paper attempts to determine the best alternative model of options pricing with the capacity to control both the level of skewness and kurtosis. It aims to replicate the effectiveness of classic stochastic and deterministic option pricing models and also establish a correlation between the underlying stock returns and their volatility. The paper follows a structural approach for analysing the Hull-White model (with two stochastic versions: non-related and correlated) with respect to the Black-Scholes model, which is a benchmark model. The focus is on fabricating such a model for predicting and protecting the market options price during uncertain financial upheavals. The suggested models have been tested in extreme conditions to determine effectiveness. Furthermore, the paper also examines the hedging effectiveness of hypothecated models.
