Radiological progression of end colostomy trephine diameter and area
(Wiley, 20181024)Background Development of a parastomal hernia is common following abdominoperineal excision (APE). The true incidence is difficult to assess fully owing to differing lengths of follow‐up and techniques used to assess ... 
Rank Histograms of Stratified Monte Carlo Ensembles
(American Meteorological Society, 20120501)The application of forecast ensembles to probabilistic weather prediction has spurred considerable interest in their evaluation. Such ensembles are commonly interpreted as Monte Carlo ensembles meaning that the ensemble ... 
Rapid intraadrenal feedback regulation of glucocorticoid synthesis.
(Royal Society, 20141112)The hypothalamicpituitaryadrenal axis is a vital neuroendocrine system that regulates the secretion of glucocorticoid hormones from the adrenal glands. This system is characterized by a dynamic ultradian hormonal ... 
Rateinduced tipping from periodic attractors: partial tipping and connecting orbits
(AIP Publishing, 20180312)We consider how breakdown of the quasistatic approximation for attractors can lead to ratedependent tipping, where a qualitative change in tracking/tipping behaviour of trajectories can be characterised in terms of a ... 
Realizable Galois module classes over the group ring for non abelian extensions
(Association des Annales de l'Institut Fourier, 2013)Given an algebraic number field k and a finite group Γ, we write ℛ(O k [Γ]) for the subset of the locally free classgroup Cl(O k [Γ]) consisting of the classes of rings of integers O N in tame Galois extensions N/k with ... 
Recent advances in the molecular epidemiology of clinical malaria
(F1000 Research Ltd, 20180730)Human malaria is a complex disease that can show a wide array of clinical outcomes, from asymptomatic carriage and chronic infection to acute disease presenting various lifethreatening pathologies. The specific outcome ... 
Recent Arctic amplification and extreme midlatitude weather
(Nature Publishing Group, 2014)The Arctic region has warmed more than twice as fast as the global average — a phenomenon known as Arctic amplification. The rapid Arctic warming has contributed to dramatic melting of Arctic sea ice and spring snow cover, ... 
Recent results on magnetic plasma turbulence
(American Institute of Physics (AIP), 20130613)Magnetic plasma turbulence is observed over a broad range of scales in the solar wind. We discuss the results of highresolution numerical simulations of magnetohydrodynamic (MHD) turbulence that models plasma motion at ... 
Recent trends and drivers of regional sources and sinks of carbon dioxide
(European Geosciences Union (EGU), 20150202)© 2015 Author(s). The land and ocean absorb on average just over half of the anthropogenic emissions of carbon dioxide (CO2) every year. These CO2 "sinks" are modulated by climate change and variability. Here we use a suite ... 
Reconciling globalmodel estimates and country reporting of anthropogenic forest CO2 sinks
(Springer Nature, 20180924)Achieving the longterm temperature goal of the Paris Agreement requires forestbased mitigation. Collective progress towards this goal will be assessed by the Paris Agreement’s Global stocktake. At present, there is a ... 
Reconciling precipitation with runoff: observed hydrological change in the midlatitudes
(American Meteorological Society, 201512)Centurylong observed gridded land precipitation datasets are a cornerstone of hydrometeorological research. But recent work has suggested that observed Northern Hemisphere midlatitude (NHML) land mean precipitation does ... 
Recurrent network dynamics reconciles visual motion segmentation and integration
(Springer Nature, 20170912)In sensory systems, a range of computational rules are presumed to be implemented by neuronal subpopulations with different tuning functions. For instance, in primate cortical area MT, different classes of directionselective ... 
Recursions associated to trapezoid, symmetric and rotation symmetric functions over Galois fields
(Elsevier, 20180414)Rotation symmetric Boolean functions are invariant under circular translation of indices. These functions have very rich cryptographic properties and have been used in different cryptosystems. Recently, Thomas Cusick proved ... 
Reduced dynamics and symmetric solutions for globally coupled weakly dissipative oscillators
(Taylor & Francis, 2005)Systems of coupled oscillators may exhibit spontaneous dynamical formation of attracting synchronized clusters with broken symmetry; this can be helpful in modelling various physical processes. Analytical computation of ... 
Reduced risk of North American cold extremes due to continued Arctic sea ice loss
(American Meteorological Society, 2014)In earlyJanuary 2014, an Arctic air outbreak brought extreme cold and heavy snowfall to central and eastern North America, causing widespread disruption and monetary losses. The media extensively reported the cold snap, ... 
A refined version of Grothendieck's anabelian conjecture for hyperbolic curves over finite fields
(American Mathematical Society, 20180329)In this paper we prove a refined version of a theorem by Tamagawa and Mochizuki on isomorphisms between (tame) arithmetic fundamental groups of hyperbolic curves over finite fields, where one “ignores” the information ... 
A refined version of Grothendieck's birational anabelian conjecture for curves over finite fields
(Elsevier / Academic Press, 20170317)In this paper we prove a refined version of Uchida’s theorem on isomorphisms between absolute Galois groups of global fields in positive characteristics, where one “ignores” the information provided by a “small” set of primes. 
Regime Change Behaviour During Asian Monsoon Onset
(American Meteorological Society, 20180327)As the ITCZ moves off the equator on an aquaplanet, the Hadley circulation transitions from an equinoctial regime with two near symmetric, significantly eddydriven cells, to a monsoonlike regime with a strong, thermally ... 
Regional carbon fluxes from land use and land cover change in Asia, 1980–2009
(IOP Publishing, 20160708)We present a synthesis of the landatmosphere carbon flux from land use and land cover change (LULCC) in Asia using multiple data sources and paying particular attention to deforestation and forest regrowth fluxes. The ... 
Regional climate impacts of stabilizing global warming at 1.5 K using solar geoengineering
(Wiley / American Geophysical Union (AGU), 20180208)The 2015 Paris Agreement aims to limit global warming to well below 2 K above preindustrial levels, and to pursue efforts to limit global warming to 1.5 K, in order to avert dangerous climate change. However, current ...
