The evolution of rhythmic cognition: New perspectives and technologies in comparative research
Music is a pervasive phenomenon in human culture, and musical rhythm is virtually present in all musical traditions. Research on the evolution and cognitive underpinnings of rhythm can benefit from a number of approaches. We outline key concepts and definitions, allowing fine-grained analysis of rhythmic cognition in experimental studies. We advocate comparative animal research as a useful approach to answer questions about human music cognition and review experimental evidence from different species. Finally, we suggest future directions for research on the cognitive basis of rhythm. Apart from research in semi-natural setups, possibly allowed by âdrum set for chimpanzeesâ prototypes presented here for the first time, mathematical modeling and systematic use of circular statistics may allow promising advances

Do red deer hinds prefer stags that produce harsh roars in mate choice contexts?
Red deer stags give two types of roars during the breeding season, termed âcommonâ and âharshâ roars. This study tested the hypothesis that the characteristic spectro-temporal structure of male harsh roars functions to directly attract females towards male callers during the breeding season. The results show that oestrous hinds look for longer towards speakers broadcasting sequences containing harsh roars, but do not preferentially approach or spend more time in close proximity to speakers broadcasting harsh roars over those broadcasting only common roars. While these observations confirm that the specific acoustic structure of male harsh roars functions to draw the attention of hinds, they are not consistent with the notion that these calls have an immediate impact on mate choice decisions by stimulating oestrous hinds to move towards male callers. Consequently, we suggest that intersexual selection through female mate choice is unlikely to be a major factor driving the evolution of male red deer harsh roars
Auctions for the support of renewable energy in the UK: updated results and lessons learnt
This is the final version. Available from AURES II via the link in this recordBackground to this study.
This report serves to restate and update the findings of AURES report D4.1-UK published in March 2016
(Fitch-Roy and Woodman 2016)1
. While the fundamental design of the UK auctions system remains largely
unchanged, substantial shifts in the policy context and the additional experience and data from two further
auction processes (one completed, another in progress at the time of writing) warrant an updated evaluation
and report.
The UK has been a frontrunner in the use of RES auctions. From early experiences with the Non Fossil-Fuel
Obligation (NFFO) auctions in the 1990s to the current auction system, first announced in 2011, the use of
competitive allocation mechanisms has been central to the UKâs approach to supporting new renewable
electricity generation projects.
However, the use and design of renewable auctions remain a source of policy debate and discussion in the
UK. For example, the potential for a combination of auction dynamics and the application of a cap on the
volume of âfuelledâ renewable technologies led to higher than necessary support costs being awarded to
some projects has been the subject of an enquiry by the national audit office (NAO 2018).
This remainder of this report adopts the following structure:
Section 2 provides an updated overview of the UK electricity sector
Section 3 outlines the key features of the UK RES auction system, including recent rule changes
Section 4 updates our earlier evaluation of the programme in light of recent auctions

Heralded Two-Photon Entanglement from Probabilistic Quantum Logic Operations on Multiple Parametric Down-Conversion Sources
An ideal controlled-NOT gate followed by projective measurements can be used
to identify specific Bell states of its two input qubits. When the input qubits
are each members of independent Bell states, these projective measurements can
be used to swap the post-selected entanglement onto the remaining two qubits.
Here we apply this strategy to produce heralded two-photon polarization
entanglement using Bell states that originate from independent parametric
down-conversion sources, and a particular probabilistic controlled-NOT gate
that is constructed from linear optical elements. The resulting implementation
is closely related to an earlier proposal by Sliwa and Banaszek
[quant-ph/0207117], and can be intuitively understood in terms of familiar
quantum information protocols. The possibility of producing a ``pseudo-demand''
source of two-photon entanglement by storing and releasing these heralded pairs
from independent cyclical quantum memory devices is also discussed.Comment: 5 pages, 4 figures; submitted to IEEE Journal of Selected Topics in

Defining incumbency: considering the UK heat sector
This is the final version of the article. Available from UKERC via the link in this record.This is working paper 1/3 from the Heat, Incumbency and Transformations (HIT) project.Incumbency is frequently considered as a barrier to the transformation of unsustainable socio-technical systems such as energy systems. However, despite wide use of the term, âincumbencyâ has never been fully or adequately defined within the sustainable transitions literature. This working paper considers the use and meaning of the term incumbency in relation to sustainable transformations, specifically in relation to the UKâs heat system. It takes ideas of incumbency from other disciplines including economics, politics and innovation. Synthesising these literatures, the paper proposes a number of characteristics of incumbency. Finally we propose a definition of incumbency in relation to sustainability transformations, which suggests that incumbents are actors already present in a specific socio-technical system, who are likely to be involved with unsustainable practices, and who possess the capacity to affect system change.UKERC is funded by The Research Councils UK Energy Programme
Policy instrument supply and demand: how the renewable electricity auction took over the world
This is the final version. Available on open access from Cogitatio Press via the DOI in this recordThe selection and design of renewable electricity support instruments is an important part of EU energy policy and central to the governance of the Energy Union. In 2014, the European Commission published updated guidelines for state aid that effectively mandate the EU-wide implementation of auctions for allocating revenue support to commercial scale renewable electricity generation. This article argues that the RES auctionâs rapid ascent towards dominance is explained by a coincidence of an activist interpretation of EU state aid law creating demand for knowledge about the instrument and the emergence of a ready source of supply from a burgeoning community of a RES auction specialists and experts. Knowledge gained through EU-wide implementation of auctions further adds to supply of auctions expertise among the community. The implications of positive feedback between instrument demand and the growing supply of knowledge about an instrument reinforces the importance of critical engagement between policymakers and policy experts.This research was supported by the UK Engineering and Physical Sciences Research Council
