Beef Cattle Instance Segmentation Using Fully Convolutional Neural Network
In this paper we present a novel instance segmentation algorithm that extends a fully convolutional network to learn to label objects separately without prediction of regions of interest. We trained the new algorithm on a challenging CCTV recording of beef cattle, as well as benchmark MS COCO and Pascal VOC datasets. Extensive experimentation showed that our approach outperforms the state-of-the-art solutions by up to 8% on our data
A classification of spherically symmetric spacetimes
A complete classification of locally spherically symmetric four-dimensional
Lorentzian spacetimes is given in terms of their local conformal symmetries.
The general solution is given in terms of canonical metric types and the
associated conformal Lie algebras. The analysis is based upon the local
conformal decomposition into 2+2 reducible spacetimes and the Petrov type. A
variety of physically meaningful example spacetimes are discussed
EFFECTS OF VARIABLE AND FIXED PRACTICE ON THE DEVELOPMENT OF JUMPING ABILITY IN YOUNG CHILDREN
The effects of variable and fixed practice regimes on the development fundamental skills are not fully understood. This study examined the effects of variable and fixed practice in
jumping skills in children aged 5 to 6 years. Twenty four children were divided into two groups and each group received fixed or variable practice in jumping skills over a period of six weeks. Jumping skill was evaluated from video records using qualitative analysis procedures. Analysis was carried out before and immediately after the six week
intervention and a retention test was conducted one week after the post test. The results indicated that the variable practice group significantly improved their jumping skill
compared to pre-test scores but the fixed practice group showed no improvements. The results suggest that variable practice is more effective in improving skill levels in
children

Stochastic parameterization: uncertainties from convection
In 2005, the ECMWF held a workshop on stochastic parameterisation, at which the convection was seen as being
a key issue. That much is clear from the working group reports and particularly the statement from working group
1 that “it is clear that a stochastic convection scheme is desirable”. The present note aims to consider our current
status in comparison with some of the issues raised and hopes expressed in that working group report
The relationship between various live animal scores/measurements and carcass classification for conformation and fatness with meat yield and distribution, and ultimate carcass value
End of project reportAccordingly, the primary objectives of the following study were to:
(1) determine the relationship of live animal muscular and skeletal scores, ultrasonically scanned muscle
and fat depth measurements of the m. longissimus dorsi, and carcass conformation and fat scores with
kill-out proportion, carcass composition and value.
(2) Specifically develop and test the accuracy of prediction equations for carcass meat, fat and bone
proportions, derived from carcass conformation and fat scores, and develop prediction equations for
total carcass composition from hind-quarter composition
The formation heritage of Jupiter Family Comet 10P/Tempel 2 as revealed by infrared spectroscopy
We present spectral and spatial information for major volatile species in
Comet 10P/Tempel 2, based on high-dispersion infrared spectra acquired on UT
2010 July 26 (heliocentric distance Rh = 1.44 AU) and September 18 (Rh = 1.62
AU), following the comet's perihelion passage on UT 2010 July 04. The total
production rate for water on July 26 was (1.90 +/- 0.12) x 10^28 molecules s-1,
and abundances of six trace gases (relative to water) were: CH3OH (1.58% +/-
0.23), C2H6 (0.39% +/- 0.04), NH3 (0.83% +/- 0.20), and HCN (0.13% +/- 0.02). A
detailed analysis of intensities for water emission lines provided a rotational
temperature of 35 +/- 3 K. The mean OPR is consistent with nuclear spin
populations in statistical equilibrium (OPR = 3.01 +/- 0.18), and the (1-sigma)
lower bound corresponds to a spin temperature > 38 K. Our measurements were
contemporaneous with a jet-like feature observed at optical wavelengths. The
spatial profiles of four primary volatiles display strong enhancements in the
jet direction, which favors release from a localized vent on the nucleus. The
measured IR continuum is much more sharply peaked and is consistent with a
dominant contribution from the nucleus itself. The peak intensities for H2O,
CH3OH, and C2H6 are offset by ~200 km in the jet direction, suggesting the
possible existence of a distributed source, such as the release of icy grains
that subsequently sublimed in the coma. On UT September 18, no obvious emission
lines were present in our spectra, nevertheless we obtained a 3-sigma upper
limit Q(H2O) < 2.86 x 10^27 molecules s-1
Identification of transcription factor contexts in literature using machine learning approaches
Background: Availability of information about transcription factors (TFs) is crucial for genome
biology, as TFs play a central role in the regulation of gene expression. While manual literature
curation is expensive and labour intensive, the development of semi-automated text mining support
is hindered by unavailability of training data. There have been no studies on how existing data
sources (e.g. TF-related data from the MeSH thesaurus and GO ontology) or potentially noisy
example data (e.g. protein-protein interaction, PPI) could be used to provide training data for
identification of TF-contexts in literature.
Results: In this paper we describe a text-classification system designed to automatically recognise
contexts related to transcription factors in literature. A learning model is based on a set of
biological features (e.g. protein and gene names, interaction words, other biological terms) that are
deemed relevant for the task. We have exploited background knowledge from existing biological
resources (MeSH and GO) to engineer such features. Weak and noisy training datasets have been
collected from descriptions of TF-related concepts in MeSH and GO, PPI data and data
representing non-protein-function descriptions. Three machine-learning methods are investigated,
along with a vote-based merging of individual approaches and/or different training datasets. The
system achieved highly encouraging results, with most classifiers achieving an F-measure above 90%.
Conclusions: The experimental results have shown that the proposed model can be used for
identification of TF-related contexts (i.e. sentences) with high accuracy, with a significantly reduced
set of features when compared to traditional bag-of-words approach. The results of considering
existing PPI data suggest that there is not as high similarity between TF and PPI contexts as we have
expected. We have also shown that existing knowledge sources are useful both for feature
engineering and for obtaining noisy positive training data
French responses to the Prague Spring: connections, (mis)perception and appropriation
Looking at the vast literature on the events of 1968 in various European countries, it is striking that the histories of '1968' of the Western and Eastern halves of the continent are largely still written separately.1 Nevertheless, despite the very different political and socio-economic contexts, the protest movements on both sides of the Iron Curtain shared a number of characteristics. The 1968 events in Czechoslovakia and Western Europe were, reduced to the basics, investigations into the possibility of marrying social justice with liberty, and thus reflected a tension within European Marxism. This essay provides an analysis specifically of the responses by the French left—the Communist Party, the student movements and the gauchistes—to the Prague Spring, characterised by misunderstandings and strategic appropriation. The Prague Spring was seen by both the reformist and the radical left in France as a moderate movement. This limited interpretation of the Prague Spring as a liberal democratic project continues to inform our memory of it
