Adaptive nowcasting of influenza outbreaks using Google searches
(2014)Seasonal influenza outbreaks and pandemics of new strains of the influenza virus affect humans around the globe. However, traditional systems for measuring the spread of flu infections deliver results with one or two weeks ... -
Increased natural mortality at low abundance can generate an Allee effect in amarine fish
(2014)Negative density dependent regulation of population dynamics promotes population growth at low abundance and is therefore vital for recovery following depletion. Inversely, any process that reduces the compensatory ... -
Oxygen consumption dynamics in steady state tumour models
(2014)Oxygen levels in cancerous tissue can have a significant effect on treatment response: hypoxic tissue is both more radioresistant and more chemoresistant than well-oxygenated tissue. While recent advances in medical imaging ... -
River temperature drives salmon survivorship
(2015)Early life is believed to be a critical stage for determining survivorship in all fish. Many studies have suggested that environmental conditions in the ocean determine the fry-to-adult survival rate of Pacific salmon but ... -
Egg shape changes at the theropod bird transition, and amorphometric study of amniote eggs
(2014)The eggs of amniotes exhibit a remarkable variety of shapes, from spherical to elongate and from symmetrical to asymmetrical. We examine eggshell geometry in a diverse sample of fossil and living amniotes using geometric ... -
Harem holding males do not rise to the challenge
(2014)The challenge hypothesis has been enormously successful in predictinginterspecific androgen profiles for vertebrate males. Nevertheless, in the absence of another theoretical framework, many researchers ‘retrofit’ the ... -
Impact behaviour of freeze-dried and fresh pomelo peel
(2015)Pomelos (Citrus maxima) are known for their thick peel which—inter alia—serves as energy dissipator when fruits impact on the ground after being shed. It protects the fruit from splitting open and thus enables the contained ... -
Climate driven tipping points could lead to sudden, high intensity parasite outbreaks
(2015)Parasitic nematodes represent one of the most pervasive and significant challenges to grazing livestock, and their intensity and distribution are strongly influenced by climate. Parasite levels and species composition have ... -
Prevalent endosymbiont zonation shapes the depth distributions of scleractinian coral species
(2015)Bathymetric distributions of photosynthetic marine invertebrate species are relatively well studied, however the importance of symbiont zonation (i.e. hosting of distinct algal endosymbiont communities over depth) indetermining ... -
Mid winter temperatures, not spring temperatures, predict breeding phenology in the European starling Sturnus vulgaris
(2015)In many species, empirical data suggest that temperatures less than 1 month before breeding strongly influence laying date, consistent with predictions that short lag times between cue and response are more reliable, ... -
Seasonal dynamics of megafauna on the deep West Antarctic Peninsula shelf in response to variable phytodetrital influx
(2014)The deep West Antarctic Peninsula (WAP) shelf is characterized by intense deposition of phytodetritus during spring/summer months, while very little food material reaches the seafloor during winter. The response of the ... -
Graphlet signature based scoringmethod to estimate protein ligand binding affinity
(2014)Over the years, various computational methodologies have been developed to understand and quantify receptor–ligand interactions. Protein–ligand interactions can also be explained in the form of a network and its properties. ... -
Fundamental formulae for wave-energy conversion
(2015)The time-average wave power that is absorbed from an incident wave by means of a wave-energy conversion (WEC) unit, or by an array of WEC units—i.e. oscillating immersed bodies and/or oscillating water columns (OWCs)—may ... -
Viewing images of snakes accelerates making judgements of their colour in humans
(2014)One of the most prevalent current psychobiological notions about human behaviour and emotion suggests that prioritization of threatening stimuli processing induces deleterious effects on task performance. In order to confirm ... -
Tooth serration morphologies in the genus Machimosaurus from the Late Jurassic of Europe
(2014)Machimosauruswas a large-bodied durophagous/chelonivorous genus of teleosaurid crocodylomorph that lived in shallow marine and brackish ecosystems during the Late Jurassic. Among teleosaurids, Machimosaurusand its sister ... -
Prognostic models in coronary artery disease
(2015)Predictive assessment of the risk of developing cardiovascular diseases is usually provided by computational approaches centred on Cox models. The complex interdependence structure underlying clinical data patterns can ... -
Fine scale dietary changes between the breeding and non breeding diet of a resident seabird
(2015)Unlike migratory seabirds with wide foraging ranges, resident seabirds forage in a relatively small range year-round and are thus particularly vulnerable to local shifts in prey availability. In order to manage their ... -
Lognormal Lorenz and normal receiver operating characteristic curves as mirror images
(2015)The Lorenz curve for assessing economic inequality depicts the relation between two cumulative distribution functions (CDFs), one for the distribution of incomes or wealth and the other for their first-moment distribution. ... -
Atomic scalemodelling of hexagonal structured metallic fission product alloys
(2015)Noble metal particles in the Mo-Pd-Rh-Ru-Tc system have been simulated on the atomic scale using density functional theory techniques for the first time. The composition and behaviour of the epsilon phases are consistent ... -
Forward flight of birds revisited. Part 1.
(2014)This paper is the first part of the two-part exposition, addressing performance and dynamic stability of birds. The aerodynamic model underlying the entire study is presented in this part. It exploits the simplicity of the ...
