Communication behaviors associated with successful conversation in semantic variant primary progressive aphasia.
(Cambridge University Press (CUP) for International Psychogeriatric Association, 2017-06-08)BACKGROUND: Primary progressive aphasia (PPA) affects a range of language and cognitive domains that impact on conversation. Little is known about conversation breakdown in the semantic variant of PPA (svPPA, also known ... -
Quantifying the food requirements and effects of food stress on bumble bee colony development
(Taylor & Francis / International Bee Research Association, 2017-05-27)Agricultural intensification has led to a reduction in semi-natural areas and in the abundance of wild flowering plants, reducing the availability of floral resources upon which pollinating insects depend. This is widely ... -
Courgette Production: Pollination Demand, Supply, and Value
(Oxford University Press (OUP) / Entomological Society of America, 2017-07-13)Courgette (Cucurbita pepo L.) production in the United Kingdom is estimated to be worth £6.7 million. However, little is known about this crop’s requirement for insect-mediated pollination (pollinator dependence) and if ... -
Prevalence of non-functional overreaching in elite male and female youth academy football players
(Taylor & Francis, 2017-06-20)Purpose: The purpose of this study was to examine the prevalence of non-functional overreaching (NFOR) and overtraining (OT) in elite male and female youth football players. Methods: Two-hundred and forty-two youth football ... -
Tpc1 is an important Zn(II)2Cys6 transcriptional regulator required for polarized growth and virulence in the rice blast fungus
(Public Library of Science, 2017-07-24)The establishment of polarity is a critical process in pathogenic fungi, mediating infection-related morphogenesis and host tissue invasion. Here, we report the identification of TPC1 (Transcription factor for Polarity ... -
Ocean forced variability of Totten Glacier mass loss
(Geological Society, 2017)A large volume of the East Antarctic Ice Sheet drains through the Totten Glacier (TG) and is thought to be a potential source of substantial global sea level rise over the coming centuries. We show the surface velocity and ... -
Limited grounding-line advance onto the West Antarctic continental shelf in the easternmost Amundsen Sea Embayment during the last glacial period.
(Public Library of Science, 2017-07-25)Precise knowledge about the extent of the West Antarctic Ice Sheet (WAIS) at the Last Glacial Maximum (LGM; c. 26.5-19 cal. ka BP) is important in order to 1) improve paleo-ice sheet reconstructions, 2) provide a robust ... -
The next steps in the study of missing individuals in networks: A comment on Smith et al. (2017)
(Elsevier, 2017-06-20)Social network analysis is now used widely to study social behaviour in humans and non-human animals, and missing individuals can represent a problem for network studies. This problem is becoming especially frequent in ... -
Palaeoecological records of coral community development on a turbid, nearshore reef complex: baselines for assessing ecological change
(Springer Verlag for International Society for Reef Studies, 2017-03-04)Understanding past coral community development and reef growth is crucial for placing contemporary ecological and environmental change within appropriate reef-building timescales. On Australia’s Great Barrier Reef (GBR), ... -
An analysis of waves underlying grid cell firing in the medial enthorinal cortex
(BioMed Central / SpringerOpen, 2017)Layer II stellate cells in the medial enthorinal cortex (MEC) express hyperpolarisation-activated cyclic-nucleotide-gated (HCN) channels that allow for rebound spiking via an Ih current in response to hyperpolaris- ing ... -
Limitations of perturbative techniques in the analysis of rhythms and oscillations
(Springer Verlag, 2012-01-31)Perturbation theory is an important tool in the analysis of oscillators and their response to external stimuli. It is predicated on the assumption that the perturbations in question are “sufficiently weak”, an assumption ... -
Ecosystem heterogeneity determines the ecological resilience of the Amazon to climate change
(National Academy of Sciences, 2015-12-28)Amazon forests, which store ∼50% of tropical forest carbon and play a vital role in global water, energy, and carbon cycling, are predicted to experience both longer and more intense dry seasons by the end of the 21st ... -
Phase-amplitude descriptions of neural oscillator models
(BioMed Central, 2013-01-24)Phase oscillators are a common starting point for the reduced description of many single neuron models that exhibit a strongly attracting limit cycle. The framework for analysing such models in response to weak perturbations ... -
Variation in stem mortality rates determines patterns of above-ground biomass in Amazonian forests: implications for dynamic global vegetation models
(Wiley, 2016-05-19)Understanding the processes that determine above-ground biomass (AGB) in Amazonian forests is important for predicting the sensitivity of these ecosystems to environmental change and for designing and evaluating dynamic ... -
Secreted Frizzled-related Protein 2 (sFRP2) Redirects Non-canonical Wnt Signaling from Fz7 to Ror2 during Vertebrate Gastrulation
(American Society for Biochemistry and Molecular Biology, 2016-04-29)Convergent extension movements during vertebrate gastrulation require a balanced activity of non-canonical Wnt signaling pathways, but the factors regulating this interplay on the molecular level are poorly characterized. ... -
Ryanodine receptor point mutations confer diamide insecticide resistance in tomato leafminer, Tuta absoluta (Lepidoptera: Gelechiidae).
(Elsevier, 2016-11-11)Insect ryanodine receptors (RyR) are the molecular target-site for the recently introduced diamide insecticides. Diamides are particularly active on Lepidoptera pests, including tomato leafminer, Tuta absoluta (Lepidoptera: ... -
Eco-city indicators: governance challenges
(WIT Press, 2012-05)According to the most recent (2011) global census of eco-city initiatives, there are currently 178 eco-city initiatives under development, representing a significant mainstreaming of urban sustainability in the last decade. ... -
The smart city and its publics: insights from across six UK cities
(Taylor & Francis (Routledge), 2017-03-07)In response to policy-makers’ increasing claims to prioritise ‘people’ in smart city development, we explore the publicness of emerging practices across six UK cities: Bristol, Glasgow, London, Manchester, Milton Keynes, ... -
ATP prevents Woronin bodies from sealing septal pores in unwounded cells of the fungus Zymoseptoria tritici
(Wiley, 2017-07-03)Septa of filamentous ascomycetes are perforated by septal pores that allow communication between individual hyphal compartments. Upon injury, septal pores are plugged rapidly by Woronin bodies (WBs), thereby preventing ... -
Leadership as social identity management: Introducing the Identity Leadership Inventory (ILI) to assess and validate a four-dimensional model
(Elsevier, 2014-01-01)Although nearly two decades of research have provided support for the social identity approach to leadership, most previous work has focused on leaders' identity prototypicality while neglecting the assessment of other ...
