Using sports infrastructure to deliver economic and social change: Lessons for London beyond 2012
Over the last two decades, there has been a
new trend emerging within sport, which has
seen a shift, from investment for the sake of
sport, to investment in sport for good (Sport
England, 2008). In the context of the latter
approach, there has been an emergence of
the use of sport to address regeneration objectives,
largely stemming from the belief of government
and other sporting and non-sporting
organizations, that it can confer a wide range
of economic and social benefits to individuals
and communities beyond those of a purely
physical sporting nature, and can contribute
positively to the revitalization of declining
urban areas (BURA, 2003). This commentary
will examine regeneration legacy in the context
of the London Olympic Games. In particular,
it will focus on the use of sports stadia
as a tool for delivering economic and social
change, and by drawing upon previous examples,
suggest lessons London can learn to
enhance regeneration legacies beyond 2012
Real Time Relativity: exploration learning of special relativity
Real Time Relativity is a computer program that lets students fly at
relativistic speeds though a simulated world populated with planets, clocks,
and buildings. The counterintuitive and spectacular optical effects of
relativity are prominent, while systematic exploration of the simulation allows
the user to discover relativistic effects such as length contraction and the
relativity of simultaneity. We report on the physics and technology
underpinning the simulation, and our experience using it for teaching special
relativity to first year university students
Natural Notation for the Domestic Internet of Things
This study explores the use of natural language to give instructions that
might be interpreted by Internet of Things (IoT) devices in a domestic `smart
home' environment. We start from the proposition that reminders can be
considered as a type of end-user programming, in which the executed actions
might be performed either by an automated agent or by the author of the
reminder. We conducted an experiment in which people wrote sticky notes
specifying future actions in their home. In different conditions, these notes
were addressed to themselves, to others, or to a computer agent.We analyse the
linguistic features and strategies that are used to achieve these tasks,
including the use of graphical resources as an informal visual language. The
findings provide a basis for design guidance related to end-user development
for the Internet of Things.Comment: Proceedings of the 5th International symposium on End-User

Combined color indexes and photometric structure of galaxies NGC 834 and NGC 1134
We present the results of BVRI photometry of two galaxies with active star
formation: NGC 834 and NGC 1134. Combined color index Q_{BVI} was used to
investigate the photometrical structure of the galaxies. Index Q_{BVI} is not
affected by internal extinction and is sensitive to the presence of blue stars.
Ring-like region with active star formation at 15" from the center reveals
itself in the Q_{BVI} map of NGC 834. Three-arm spiral structure is well-seen
on the Q_{BVI} map of NGC 1134.
We propose to use the combined indexes Q_{BVI} and similarly defined indices
as a tracers of Star Formation activity and structure of dusty galaxies.Comment: 3 pages, 4 embedded figures, LaTeX2e, using the EslabStyle.cls file,

Star counts in NGC 6397
I-band CCD images of a large area of the nearby globular cluster NGC~6397
have been used to construct a surface density profile and two luminosity and
mass functions. The surface density profile extends out to 14\arcm from the
cluster center and shows no sign of a tidal cutoff. The inner profile is a
power-law with slope -0.8 steepening to -1.7 outside of 1\arcm. The mass
functions are for fields at 4\arcm\ and 11\arcm from the cluster center and
confirm the upturn in the mass function for stars less massive than about 0.4
M\solar. There appears to be an excess of low-mass stars over higher-mass stars
in the outer field with respect to the inner, in qualitative agreement with
expectations for mass segregation.Comment: 16 pages + 7 pages of tables, LaTeX using AASTeX macros, 11 figures

The age of data-driven proteomics : how machine learning enables novel workflows
A lot of energy in the field of proteomics is dedicated to the application of challenging experimental workflows, which include metaproteomics, proteogenomics, data independent acquisition (DIA), non-specific proteolysis, immunopeptidomics, and open modification searches. These workflows are all challenging because of ambiguity in the identification stage; they either expand the search space and thus increase the ambiguity of identifications, or, in the case of DIA, they generate data that is inherently more ambiguous. In this context, machine learning-based predictive models are now generating considerable excitement in the field of proteomics because these predictive models hold great potential to drastically reduce the ambiguity in the identification process of the above-mentioned workflows. Indeed, the field has already produced classical machine learning and deep learning models to predict almost every aspect of a liquid chromatography-mass spectrometry (LC-MS) experiment. Yet despite all the excitement, thorough integration of predictive models in these challenging LC-MS workflows is still limited, and further improvements to the modeling and validation procedures can still be made. In this viewpoint we therefore point out highly promising recent machine learning developments in proteomics, alongside some of the remaining challenges
Persistent punishment : users views of short prison sentences
Semi-structured interviews were conducted of 22 prisoners to gather information about the characteristic features of short prison sentences. Themes raised in comments included: the frequency and quality of sentences, addiction, family, and penal legitimacy. Most of the participants had extensive experience of prison, and the effects of this played out across sentences and years, accumulating and amplifying impacts. And, despite expressions of guilt and remorse, most participants saw their sentence as unjust, and mainly a reaction to offending history. We conclude by suggesting the need for research to shift focus from evaluating individual penal interventions towards more holistic and narrative accounts that cut across sentences
The Swift-BAT hard X-ray sky monitoring unveils the orbital period of the HMXB IGR J16493-4348
IGR J16493-4348 is a supergiant high mass X-ray binary discovered by INTEGRAL
in 2004. The source is detected at a significance level of standard
deviations in the Swift-BAT survey data collected during the first 54 months of
the Swift mission. The timing analysis reveals an orbital period of 6.78
days and the presence of a full eclipse of the compact ob\ ject. The dynamical
range (variability up to a factor 20) observed during the BAT monitoring
suggests that IGR J16493-4348 is a wind-fed system. The derived semi-major axis
of the binary system is \sim55 R_{\sun} with an orbit eccentr\ icity lower
than 0.15.Comment: 4 pages, 6 figures. Accepted for publication in MNRA
Comparison of data on Mutation Frequencies of Mice Caused by Radiation - Low Dose Model -
We propose LD(Low Dose) model, the extension of LDM model which was proposed
in the previous paper [Y. Manabe et al.: J. Phys. Soc. Jpn. 81 (2012) 104004]
to estimate biological damage caused by irradiation. LD model takes account of
all the considerable effects including cell death effect as well as
proliferation, apoptosis, repair. As a typical example of estimation, we apply
LD model to the experiment of mutation frequency on the responses induced by
the exposure to low levels of ionizing radiation. The most famous and extensive
experiments are those summarized by Russell and Kelly [Russell, W. L. & Kelly,
E. M: Proc. Natl Acad. Sci. USA 79 (1982) 539-541], which are known as
'Mega-mouse project'. This provides us with important information of the
frequencies of transmitted specific-locus mutations induced in mouse
spermatogonia stem-cells. It is found that the numerical results of the
mutation frequency of mice are in reasonable agreement with the experimental
data: the LD model reproduces the total dose and dose rate dependence of data
reasonably. In order to see such dose-rate dependence more explicitly, we
introduce the dose-rate effectiveness factor (DREF). This represents a sort of
preventable effects such as repair, apoptosis and death of broken cells, which
are to be competitive with proliferation effect of broken cells induced by
irradiation.Comment: subimitting to J. Phys. Soc. Jpn, 32 pages, 8 figure
