Report on the Information Retrieval Festival (IRFest2017)
The Information Retrieval Festival took place in April 2017 in Glasgow. The focus of the workshop was to bring together IR researchers from the various Scottish universities and beyond in order to facilitate more awareness, increased interaction and reflection on the status of the field and its future. The program included an industry session, research talks, demos and posters as well as two keynotes. The first keynote was delivered by Prof. Jaana Kekalenien, who provided a historical, critical reflection of realism in Interactive Information Retrieval Experimentation, while the second keynote was delivered by Prof. Maarten de Rijke, who argued for more Artificial Intelligence usage in IR solutions and deployments. The workshop was followed by a "Tour de Scotland" where delegates were taken from Glasgow to Aberdeen for the European Conference in Information Retrieval (ECIR 2017
Further education in transition
This paper provides an overview of the national perspective in further education (FE) developments in Information and Learning Technology (ILT) since 1992, from the unique perspective of a number of key staff members at the British Educational Communications and Technology Agency (Becta) and a member of staff with a role in quality improvement in the Further Education Funding Council (FEFC). It sets in context the research reported in this section in the papers by Cockrill et al. and CavenâAtack
On blocks of Deligne's category Rep(S_t)
Recently P. Deligne introduced the tensor category Rep(S_t) (for t not
necessarily an integer) which in a certain precise sense interpolates the
categories Rep(S_d) of representations of the symmetric groups S_d. In this
paper we describe the blocks of Deligne's category Rep(S_t).Comment: 43 pages, final version, includes an added appendix as well as other

An update on nuclear calcium signalling
Over the past 15 years or so, numerous studies have sought to characterise how nuclear calcium (Ca2+) signals are generated and reversed, and to understand how events that occur in the nucleoplasm influence cellular Ca2+ activity, and vice versa. In this Commentary, we describe mechanisms of nuclear Ca2+ signalling and discuss what is known about the origin and physiological significance of nuclear Ca2+ transients. In particular, we focus on the idea that the nucleus has an autonomous Ca2+ signalling system that can generate its own Ca2+ transients that modulate processes such as gene transcription. We also discuss the role of nuclear pores and the nuclear envelope in controlling ion flux into the nucleoplasm
Circuit Design for Predictive Maintenance
Industry 4.0 has become a driver for the entire manufacturing industry. Smart
systems have enabled 30% productivity increases and predictive maintenance has
been demonstrated to provide a 50% reduction in machine downtime. So far, the
solution has been based on data analytics which has resulted in a proliferation
of sensing technologies and infrastructure for data acquisition, transmission
and processing. At the core of factory operation and automation are circuits
that control and power factory equipment, innovative circuit design has the
potential to address many system integration challenges. We present a new
circuit design approach based on circuit level artificial intelligence
solutions, integrated within control and calibration functional blocks during
circuit design, improving the predictability and adaptability of each component
for predictive maintenance. This approach is envisioned to encourage the
development of new EDA tools such as automatic digital shadow generation and
product lifecycle models, that will help identification of circuit parameters
that adequately define the operating conditions for dynamic prediction and
fault detection. Integration of a supplementary artificial intelligence block
within the control loop is considered for capturing non-linearities and
gain/bandwidth constraints of the main controller and identifying changes in
the operating conditions beyond the response of the controller. System
integration topics are discussed regarding integration within OPC Unified
Architecture and predictive maintenance interfaces, providing real-time updates
to the digital shadow that help maintain an accurate, virtual replica model of
the physical system.Comment: 4 pages, 4 figures, position pape
