    Abstract–In this study, we conduct a detailed analysis of the Košice meteorite fall (February28, 2010), to derive a reliable law describing the mass distribution among the recovered fragments. In total, 218 fragments of the Košice meteorite, with a total mass of 11.285 kg, were analyzed. Bimodal Weibull, bimodal Grady, and bimodal lognormal distributions are found to be the most appropriate for describing the Košice fragmentation process. Based on the assumption of bimodal lognormal, bimodal Grady, bimodal sequential, and bimodal Weibull fragmentation distributions, we suggest that, prior to further extensive fragmentation in the lower atmosphere, the Košice meteoroid was initially represented by two independent pieces with cumulative residual masses of approximately 2 and 9 kg, respectively. The smaller piece produced about 2 kg of multiple lightweight meteorite fragments with the mean around 12 g. The larger one resulted in 9 kg of meteorite fragments, recovered on the ground, including the two heaviest pieces of 2.374 kg and 2.167 kg with the mean around 140 g. Based on our investigations, we conclude that two to three larger fragments of 500–1000 g each should exist, but were either not recovered or not reported by illegal meteorite hunters.

    Single-document summarization aims to reduce the size of a text document while preserving the most important information. Much work has been done on open-domain summarization. This paper presents an automatic way to mine domain-specific patterns from text documents. With a small amount of effort required for manual selection, these patterns can be used for domain-specific scenario-based document summarization and information extraction. Our evaluation shows that scenario-based document summarization can both filter irrelevant documents and create summaries for relevant documents within the specified domain.

    Two experiments investigated the perception of compound vs. phrasal stress and narrow focus in normally hearing children and children with Cochlear Implants (CI). Additionally, we investigated whether musical experience would predict children’s performance in these tasks. The results showed no difference between CI and normal-hearing (NH) children in either experiment. However, whereas we found no clear effect of age in the children’s stress detection, there was a clear age related trajectory in the ability to recognise (narrow) focus. Moreover, this trend was similar to what has been found previously for English children. Importantly, prior music experience was significantly linked to CI children’s perception of focus.

    Current genomic prediction equations, when carried out in multiple populations with admixed structures ignore structure and assume these populations are uniform. The observed reliabilities of direct genomic breeding values (DGV) for unproven bulls in these populations so far have been low. The current study evaluated reliabilities of DGV in selection candidates using multi-trait random regression model which account for interactions between marker effects and breed of origin in the admixed Nordic Red dairy cattle. Our breed-specific model used breed proportions (BP) as random predictors and deregressed proofs of estimated breeding values (DRP) as response variables weighted by approximated reliability of DRP. Reliabilities were explored as squared correlation between DRP and DGV, weighted by the mean reliability of DRP. Estimated reliabilities were low for milk (0.32) and protein (0.32) and slightly higher (0.42) for fat. Observed reliabilities were similar to those estimated assuming homogenous structure. The Nordic Red cattle is admixed but closely related, thus, the model under investigation may have been unable to differentiate additive genetic effects by breed of origin with a medium dense marker data

    This study investigated the number and nature of gifted female and male students’ scientific, societal, and moral questions concerning science. The participants (N=658) of this study were 16-19 year-old international students from 55 countries, and two continents, Asia and Europe. They applied to participate in the Millennium Youth Camp held in 2011 in Finland. The students came from scientifically and mathematically oriented schools and they had shown an interest towards science through competitions, school success, and their own research. The students were asked to formulate questions they would like to get answers to during the camp. The nature and number of the students’ questions were analyzed with qualitative and quantitative content analysis. The results showed that the boys asked more scientific questions than the girls, and the girls asked more societal questions than the boys. The students asked less questions about morality than scientific or societal questions. The most common questions about morality were related to pollution and fresh air, environmental problems, and water protection. The results point to the need for teachers to teach socioscientific issues and discuss moral questions related to science. This should be done to increase moral sensitivity and influence the future of humankind.

    A visual world eye-tracking study investigated the activation and persistence of implicit causality information in spoken language comprehension. We showed that people infer the implicit causality of verbs as soon as they encounter such verbs in discourse, as is predicted by proponents of the immediate focusing account (Greene & McKoon, 1995; Koornneef & Van Berkum, 2006; Van Berkum, Koornneef, Otten, & Nieuwland, 2007). Interestingly, we observed activation of implicit causality information even before people encountered the causal conjunction. However, while implicit causality information was persistent as the discourse unfolded, it did not have a privileged role as a focusing cue immediately at the ambiguous pronoun when people were resolving its antecedent. Instead, our study indicated that implicit causality does not affect all referents to the same extent, rather it interacts with other cues in the discourse, especially when one of the referents is already prominently in focus.

    We compute AC electrical transport at quantum Hall critical points, as modeled by intersecting branes and gauge/gravity duality. We compare our results with a previous field theory computation by Sachdev, and find unexpectedly good agreement. We also give general results for DC Hall and longitudinal conductivities valid for a wide class of quantum Hall transitions, as well as (semi)analytical results for AC quantities in special limits. Our results exhibit a surprising degree of universality; for example, we find that the high frequency behavior, including subleading behavior, is identical for our entire class of theories.

    306-channel magnetoencephalography, coregistered with high-resolution volumetric magnetic resonance imaging, was used with 10 healthy participants to test if repetition adapts subsequent processing of sounds in a sequence and whether this adaptation influenced the orientation of the dipolar sources in the auditory cortex. Auditory Nlm responses to 1 kHz pure tones were indexed by clusters of sensors situated bilaterally over the temporal lobes. Nlm was augmented in amplitude at an interstimulus interval of 16 s relative to 1 s.This neuromagnetic amplitude augment occurred in dipoles in the vicinity of the auditory cortex, without significant shifts in the dipolar orientation. Recent repetition thus adapts auditory cortical neurons, in a manner subject to recovery after a period of silence.

    This paper describes a plug-in component to extend the PULS information extraction framework to analyze Russian-language text. PULS is a comprehensive framework for information extraction (IE) that is used for analysis of news in several scenarios from English-language text and is primarily monolingual. Although monolinguality is recognized as a serious limitation, building an IE system for a new language from the bottom up is very labor-intensive. Thus, the objective of the present work is to explore whether the base framework can be extended to cover additional languages with limited effort, and to leverage the pre-existing PULS modules as far as possible, in order to accelerate the development process. The component for Russian analysis is described and its performance is evaluated on two news-analysis scenarios: epidemic surveillance and cross-border security. The approach described in the paper can be generalized to a range of heavily-inflected languages.
