Fraternal cooperation of hierarchical cancer parallels metazoan multicellularity and eusociality

open access: yesBiological Reviews, EarlyView.
ABSTRACT Metazoan multicellularity and eusociality — both outcomes of the fraternal major transitions — have numerous features in common such as uneven distribution of group‐establishing potential. In addition to this framework, I argue herein that the group‐forming principles of metazoan multicellularity and eusociality are analogous to hierarchical ...

Habits Revealed

open access: yesReview of Economic Studies, 2010
This paper sets out necessary and sufficient empirical conditions for rational intrinsic habits models in the revealed preference tradition of Samuelson (1948), Houthakker (1950), Afriat (1967), and Browning (1989). The conditions in the paper are shown to be computationally straightforward and to yield set identification for certain features of the ...

Democratising Multi‐Projector Displays

open access: yesComputer Graphics Forum, EarlyView.
Spatially augmented reality (SAR) transforms large, surround, collaborative experiences out of VR/AR headsets to the real world by merging content from projectors with the physical environment. This detailed state‐of‐the‐art survey reports on the advancements in multi‐projector aggregation and hardware technologies used to achieve SAR and build ...

Multiverse Predictions for Habitability: Fraction of Life That Develops Intelligence

open access: yesUniverse, 2019
Do mass extinctions affect the development of intelligence? If so, we may expect to be in a universe that is exceptionally placid. We consider the effects of impacts, supervolcanoes, global glaciations, and nearby gamma ray bursts, and how their rates ...

Evaluating the effect of four unknown parameters included in a latitudinal energy balance model on the habitability of exoplanets

open access: yesOpen Astronomy, 2020
Among different models for determining the habitable zone (HZ) around a star, a Latitudinal Energy Balance Model (LEBM) is very beneficial due to its parametricity which keeps a good balance between complexity and simulation time.

Habitable Climate Scenarios for Proxima Centauri b With a Dynamic Ocean

open access: yes, 2017
The nearby exoplanet Proxima Centauri b will be a prime future target for characterization, despite questions about its retention of water. Climate models with static oceans suggest that an Earth-like Proxima b could harbor a small dayside region of ...

Visual Arts, Insecurity and an Elusive Peace in Casamance, Senegal

open access: yesInternational Journal of Art &Design Education, EarlyView.
Abstract The separatist rebellion in Casamance, southern Senegal, has driven what is arguably the longest‐running intra‐state conflict in West Africa. Spanning over four decades, it has affected successive generations through insecurity (including armed violence and landmine use); economic disruption; trauma; human displacement (both internal and into ...

Tides and the Evolution of Planetary Habitability

open access: yes, 2008
Tides raised on a planet by its host star's gravity can reduce a planet's orbital semi-major axis and eccentricity. This effect is only relevant for planets orbiting very close to their host stars.

Habit and persistence

open access: yesJournal of the Experimental Analysis of Behavior, 2023
AbstractVoluntary behaviors (operants) can come in two varieties: Goal‐directed actions, which are emitted based on the remembered value of the reinforcer, and habits, which are evoked by antecedent cues and performed without the reinforcer's value in active memory.
