Molecular phylogenetic analysis of three groups of Asian epilachnine ladybird beetles recognized by the female internal reproductive organs and modes of sperm transfer

We determined partial sequences of the nuclear 28S ribosomal RNA gene (717 base pairs) and mitochondrial DNA NADH-dehydrogenase subunit 2 gene (535 base pairs) of 25 species of phytophagous ladybird beetles from Asia that comprise 16 species of the genus Henosepilachna and nine species of the genus Epilachna, and reconstructed the phylogenetic trees for each gene by the maximum parsimony and maximum likelihood methods. The estimated phylogenetic relationships were consistent with those obtained by the mode of sperm transfer and female internal reproductive system, and supported an earlier assumption that very similar elytral spot patterns of some sympatric members of epilachnine beetles evolved independently.
Templated growth of textured and luminescent CaS : Eu thin films by a low-temperature solvothermal process

The direct growth of luminescent sulfide thin films onto templated substrates was realized with a solvothermal synthesis method. The as-grown layers of SrS : Eu and CaS : Eu emit a bright and homogeneous photoluminescence, peaking at 610 nm and 650 nm, respectively. X-ray diffraction measurements showed that the layers grown at a temperature of only 200 °C are strongly crystalline, with (2 0 0) out-of-plane orientation. Using silicon substrates, almost epitaxial growth could be obtained. Electron microscopy was used to study the growth, morphology and texture of the thin films. The main advantages of this innovative approach for the production of sulfide layers are the low-temperature process and scalability.
Cerebral Biophoton Emission as a Potential Factor in Non - Local Human - Machine Interaction

Subjects were instructed to employ intention to affect the direction of random number generation from a device located on their right side at 1 m distance. Biophoton emissions from the right hemisphere were recorded simultaneously. Significant increases (~3.5 ∙10 - 12 W ∙m - 2 ) in photon radiant flux density occurred when there were marked deviations from random variations suggesting that the correlative variable for intent was coupled to cerebral photon emission. Cross - spectral analyses indicated a significant coupling betwe en photon density and deviation from random variation within the 6 mHz range. The estimated raw power over the most likely area of influence (10 - 10 m 2 ) over the peak duration would be within the order of 10 - 20 J. This quantum is associated with single acti on potentials and the difference in energy equivalents after Lorentz contraction between the electron’s Compton wavelength and traditional particle width. The resulting ~1.5 µm wavelength for this energy, which matches Bohr’s solution, is also within the w idth of the synapse. The moderately strong correlation between the strength of the coherence between the deviations during intention and the photon emission and the entropy within the temporal distribution of the “random” number variations in the mHz range suggests that a shared source with the earth’s free background oscillations may be involved. Our results strongly indicate that photon - electron interactions between cerebral function and electronic devices that reflect “random” electron tunnelling may be more powerful than accommodated by classical physics and indicate the powerful role of a neuroquantological process.
Current changes in the south Spitsbergen landscape : a comparison of the Sørkappland eastern and western coasts

A complex process of environmental and landscape changes has persisted in south Spitsbergen since the beginning of the 20 century, due to climate warming after the Little Ice Age (LIA). Although their general direction is the same in the whole region, its eastern and western coasts differ significantly in the intensity of changes. That has been evidenced by the results of the Jagiellonian University investigations (first of all physico-geographical mapping, interpretation of aerial photos, analysis of satellite data) carried out in Sørkappland – the southern Spitsbergen peninsula – since 1980. An extraordinary climate warming from 1980–1989 to 2000–2009 has resulted in intensified glacial recession, appearance of new landforms and deposits, changes in water drainage and network, and plant succession in the eastern peninsula’s coast. This narrow coast has become released from the majority of (former) tide-water glaciers and exposed to sea action, much more intensive due to a shortened sea-ice season. Its coastline has changed dramatically: a large coastal plain with a lake has declined, the Hambergbukta new fjord and new coastal plains with lakes have appeared. Hence, a completely new coastal landscape has been formed there. The western peninsula coast, which consists of wide coastal plains vegetated by tundra, has not undergone such a significant transformation. Its coastline has been slightly translocated by sea abrasion or accumulation, apart from its section at only the tide-water glacier’s front, where a large bay with a new coastline appeared as a result of the glacier’s recession.
Antioxidant Properties of Roselle Vinegar Production by Mixed Culture of Acetobacter aceti and Acetobacter cerevisiae

Roselle (Hibiscus sabdariffa) has been used in folk medicine and as a treatment for diseases and cancer. The objective of this study was to enhance the acetic acid production and the antioxidant activities (AOA) of Roselle vinegar using mixed culture fermentation. The Roselle wine was produced in a batch reactor. The kinetic parameters obtained for wine fermentation using Saccharomyces cerevisiae were: maximum ethanol production = 63.47 g.L-1, ethanol production rate = 2.25 g.L-1. hr-1, product (ethanol) yield coefficient = 0.45 and cell mass yield coefficient = 1.53. Using a mixed culture of Acetobacter aceti and Acetobacter cervisiae, the wine vinegar process optimization ranges for initial concentrations of ethanol and acetic acid as independent variables were 63.47 and 69.21 g.L-1, respectively. Roselle was processed into juice fermentation and vinegars. The total phenolics, total anthocyanins, and antiradical activity (1-1 diphenyl-2-picryl hydrazyl radical-scavenging (DPPH) method) were determined. Acetification increased the total anthocyanin content, total polyphenols and antioxidant activities. Correlations indicated that anthocyanins made greater significant contributions than did phenolics to the antioxidant activities of the products. The antiradical activity of wine from Roselle juice was high with an effective concentration which inhibited the DPPH activity by 50% (EC50) of 14.95 mg.L-1. The antioxidant activity of the vinegar product was high with an EC50 of 0.72 mg.L-1. The results indicated that fermentation is a better method for obtaining higher antioxidant activity of Roselle products. Furthermore, acetification significantly increased the anthocyanins and antioxidant activities.
Acid hydrolysis of easilydispersed andmicroaggregate-derived silt-and clay-sized fractions to isolate resistant soil organicmatter

The current paradigm in soil organic matter (SOM) dynamics is that the proportion of biologically resistant SOM will increase when total SOM decreases. Recently, several studies have focused on identifying functional pools of resistant SOM consistent with expected behaviours. Our objective was to combine physical and chemical approaches to isolate and quantify biologically resistant SOM by applying acid hydrolysis treatments to physically isolated siltand clay-sized soil fractions. Microaggegrate-derived and easily dispersed siltand clay-sized fractions were isolated from surface soil samples collected from six long-term agricultural experiment sites across North America. These fractions were hydrolysed to quantify the non-hydrolysable fraction, which was hypothesized to represent a functional pool of resistant SOM. Organic C and total N concentrations in the four isolated fractions decreased in the order: native > no-till > conventional-till at all sites. Concentrations of non-hydrolysable C (NHC) and N (NHN) were strongly correlated with initial concentrations, and C hydrolysability was found to be invariant with management treatment. Organic C was less hydrolysable than N, and overall, resistance to acid hydrolysis was greater in the silt-sized fractions compared with the claysized fractions. The acid hydrolysis results are inconsistent with the current behaviour of increasing recalcitrance with decreasing SOM content: while %NHN was greater in cultivated soils compared with their native analogues, %NHC did not increase with decreasing total organic C concentrations. The analyses revealed an interaction between biochemical and physical protection mechanisms that acts to preserve SOM in fine mineral fractions, but the inconsistency of the pool size with expected behaviour remains to be fully explained.
Seismic and geodetic evidence for grounding‐line control of Whillans Ice Stream stick‐slip events

The tidally modulated, stick‐slip events of Whillans Ice Stream in West Antarctica produce seismic energy from three locations near the grounding line. Using ice velocity records obtained by combining time series from colocated broadband seismometers and GPS receivers installed on the ice stream during the 2010–2011 and 2011–2012 austral summers, along with far‐field seismic recordings of elastic waves, we locate regions of high rupture velocity and stress drop. These regions, which are analogous to “asperities” in traditional seismic fault studies, are areas of elevated friction at the base of the ice stream. Slip events consistently initiate at one of two locations: near the center of the ice stream, where events associated with the Ross Sea high tide originate, or a grounding‐line spot, where events associated with the Ross Sea low tide initiate, as well as occasional high‐tide events following a skipped low‐tide event. The grounding‐line site, but not the central site, produces Rayleigh waves observable up to 1000 km away, through fast expansion of the slip area. Grounding‐line initiation events also show strong directivity in the downstream direction, indicating initial rupture propagation at 1.5 km/s, compared to an average of 0.150 km/s for the entire slip event. Following slip initiation, additional seismic energy is produced from two sources located near the grounding line: first at the downstream end of Subglacial Lake Engelhardt and second toward the farthest downstream extent of the ice stream. This evidence suggests that the stronger, higher‐friction material along the grounding line controls motion throughout the stick‐slip region.
Crossmodal priming of unfamiliar faces supports early interactions between voices and faces in person perception

ABSTRACT Although faces and voices are important sources of information for person recognition, it is unclear whether these cues interact at a late stage to act as complementary, unimodal sources for person perception or whether they are integrated early on to provide a multisensory representation of a person in memory. Here we used a crossmodal associative priming paradigm to test whether unfamiliar voices which were recently paired with unfamiliar faces could subsequently prime familiarity decisions to the related faces. Based on our previous study, we also predicted that distinctive voices would enhance the recognition of faces relative to typical voices. In Experiment 1 we found that voice primes facilitated the recognition of related target faces at test relative to learned but unrelated voice primes. Furthermore, face recognition was enhanced by the distinctiveness of the paired voice primes. In contrast, we found no evidence of priming with arbitrary sounds (Experiment 2), confirming the special status of the pairing between voices and faces for person identification. In Experiment 3, we established that voice primes relative to no prime facilitated familiarity decisions to related faces. Our results suggest a strong association between newly learned voices and faces in memory. Furthermore, the distinctiveness effect found for voice primes on face recognition suggests that the quality of the voice can affect memory for faces. Our findings are discussed with regard to existing models of person perception and argue for interactions between voices and faces that converge early in a multisensory representation of persons in long-term memory.
Phase behavior of rounded hard-squares

Recently, Zhao et al. [Proc. Natl. Acad. Sci. U. S. A. , 2011, 108, 2684] reported the phase behavior of monolayers of polymeric Brownian squares platelets. As the density is increased, this system exhibits the formation of two crystal structures not expected for particles with square symmetry, namely, a hexagonal rotator crystal phase and a rhombic crystal phase. Molecular simulations by Wojciechowski and Frenkel [Comp. Met. Sci. Technol. , 2004 10, 235] had predicted instead the formation of tetratic and square crystal phases. In this work, we report Monte Carlo simulation results of rounded hard squares of varying degrees of roundness, hence interpolating between disks and perfect squares. Our simulations show that the roundness of the particles gives rise to the phases observed by Zhao et al. and further provide a roadmap for the regions of stability of different ordered phases as a function of particle roundness. In particular, our results suggest that depending on the degree of roundness, the isotropic phase would transition either into a hexagonal rotator phase through a hexatic-like intermediate, into a square phase through a tetratic-like intermediate, or (in a narrow range of crossover values of roundness) into a novel polycrystalline phase containing domains with square order in coexistence with clusters of particles having a weak hexagonal order.

A new Pliensbachian (Early Jurassic) neoselachian shark fauna from southern Sweden

Hettangian to Pliensbachian neoselachian tooth assemblages from marine deposits in northwest Europe are dominated by palaeospinacids. In the Toarcian, elasmobranch faunas tend to be more diverse and several other neoselachian groups have their first occurrence. A small, but surprisingly diverse, neoselachian tooth assemblage, comprising seven taxa, has been extracted from Pliensbachian sediments within the Rya Formation in southern Sweden. The fauna includes five synechodontiform species; Synechodus occultidens, S. enniskilleni, 'Synechodus' sp. , Paraorthacodus sp. , and Sphenodus sp. The remaining two species include Hexanchidae indet. and Agaleus dorsetensis. The exclusively Early Jurassic A. dorsetensis is separated from all other neoselachians on the basis of tooth morphology and is here included in the new, monotypic family Agaleidae nov. The assemblage from the Rya Formation is the first selachian fauna to be recorded from the Jurassic of Sweden and it has a composition quite different from contemporary faunas found in other areas of Europe. The neoselachian part of the fauna is more diverse while hybodont sharks are represented solely by a single species.
Misperception and Technology Adoption

There are remarkably large differences in the timin g of adoption and intensity of use of new technologies. What factors determine such differenc es? Is it because of higher returns to using the new technology, or systematic misperceptions about their expected returns? We address these questions using a unique registry dataset for a qua rter-million patients with implantable cardiac defibrillators (ICDs), a medical device that reduce s the risk of sudden cardiac arrest. We develop a structural model of Bayesian learning that allows for misperception of provider skill that can lead to overly optimistic or pessimistic behavior. Briefly, our estimates suggest that for ICDs, the most rapid adopters were overly optimistic, leading both to high utilization rates and for these early innovators, below-average returns to the technology. We find that mispercep tion can explain half of hospital-level variation in risk-adjusted mortal ity and nearly three-quarters of the variation in adoption and use. In addition, the model predicts, correctly, that those hospitals exhibiting the greatest optimism about their own ability are the o nes that scale back quickest. These results suggest an important role for misperception (both o ptimistic and pessimistic) in explaining the wide variation in adoption and use of new technolog ies, and suggests caution in equating rapid diffusion to productivity gains. We are grateful for financial support from the Nati onal Institute on Aging (P01-AG19783 and U01-AG046830). In addition, we are indebted to Greg Roth, Peter Groeneveld, Kimon Bekelis, and to seminar participants at the World Bank, the University of Chicago, Princeton University, the University of Virginia, The University of Illin ois, Emory University, NBER, and the Federal Reserve Bank of Chicago for very helpful comments a nd suggestions.

Subjective Emotions vs. Verbalizable Emotions in Web Texts

Cognition and emotions are inseparable. Still, it is not clear to which extent emotions can be characterized by words and how much of emotional feelings are non-verbalizable. Here we approach this topic by comparing the structure of the emotional space as revealed by word contexts to that in subjective judgments, as studied in the past. The number of independent emotions and categories of emotions is a key characteristic of the emotional space. Past research were based exclusively on perceived subjective similarities by participants of experiments. Here we propose and examine a new approach, the similarities between emotion names are obtained by comparing the contexts in which they appear in texts retrieved from the World Wide Web. The developed procedure measures a similarity matrix among emotional names as dot products in a linear vector space of contexts. This matrix was then explored using Multidimensional Scaling and Hierarchical Clustering. Our main findings, namely, the underlying dimension of the emotion space and the categories of emotion names, were consistent with those based on subjective judgments. We conclude that a significant part of emotional experiences is verbalizable. Future directions are discussed.
Swarm Intelligence? Stock Opinions of the Crowd and Stock Returns

We find that crowds’ analyses of stocks, disclosed on a social investment platform, provide explanatory power for stock returns. Exploiting a novel dataset that contains more than 14.9 million individual stock assessments for 10,452 stocks over the period from August 1, 2007, to July 15, 2015, our study shows that social networks may add valuable information for explaining future and abnormal stock returns. We find that a portfolio based on social media opinions yields a monthly excess return of 3.3%. We provide a theoretical rationale for our findings based on the argument that the platform is subject to fewer institutional restrictions and is designed more efficiently for prediction than financial markets.
Effect of dietary hydrochloric acid (HCL) supplementation on performance and physiological response in cockerels.

Concentrated HCl of 11.6 molar concentrations was supplemented in cockrel feed at 0.0 (control) 0.25, 0.50, 0.75 and 1.00m1/kg feed in a 28 day experiment. The chicks were slaughtered on day 30, performance characteristic and physiological indices were investigated. There was no significant difference (p>0.05) between control and HCl treatment for feed intake, crude protein intake and feed: gain ratio. Significant difference (p potential for improving feed utilization in cockerels.
Towards Automatic Fake News Detection: Cross-Level Stance Detection in News Articles

In this paper, we propose to adapt the four-staged pipeline proposed by Zubiaga et al. (2018) for the Rumor Verification task to the problem of Fake News Detection. We show that the recently released FNC-1 corpus covers two of its steps, namely the Tracking and the Stance Detection task. We identify asymmetry in length in the input to be a key characteristic of the latter step, when adapted to the framework of Fake News Detection, and propose to handle it as a specific type of Cross-Level Stance Detection. Inspired by theories from the field of Journalism Studies, we implement and test two architectures to successfully model the internal structure of an article and its interactions with a claim.
Factors influencing the organizational adoption of cloud computing: a survey among cloud workers

Cloud computing presents an opportunity for organizations to leverage affordable, scalable, and agile technologies. However, even with the demonstrated value of cloud computing, organizations have been hesitant to adopt such technologies. Based on a multi-theoretical research model, this paper provides an empirical study targeted to better understand the adoption of cloud services. An online survey addressing the factors derived from literature for three specific popular cloud application types (cloud storage, cloud mail and cloud office) was undertaken. The research model was analyzed by using variance-based structural equation modelling. Results show that the factors of compatibility, relative advantage, security & trust, as well as, a lower level of complexity lead to a more positive attitude towards cloud adoption. Complexity, compatibility, image and security & trust have direct and indirect effects on relative advantage. These factors further explain a large part of the attitude towards cloud adoption but not of its usage.
