The Stern Review reported a social cost of carbon of over $300/tC, calling for ambitious climate policy. We here conduct a systematic sensitivity analysis of this result on two crucial parameters: the rate of pure time preference, and the rate of risk aversion. We show that the social cost of carbon lies anywhere in between 0 and $120 000/tC. However, if we restrict these two parameters to matc...

Aspect mining tries to identify crosscutting concerns in the code of existing systems and thus supports their adaption to an aspect-oriented design. A semi-automatic static aspect mining approach is described, where the program’s control flow graphs are investigated for recurring execution patterns based on different constraints, such as the requirement that the patterns have to exist in differ...

A large number of scanner generators have been developed. Since they are restricted to the longestmatch rule, they are unsuitable for an incremental environment. We present the ALADIN system, which is able to deliver more than a single token if required. Thus, an ambiguity may be passed to the calling instance. Beyond this ‘incremental feature’, ALADIN is a well-structured and easy-to-understan...

Males of the Palaearctic red cicada, Tibicina haematodes, produce calling songs that are attractive to both sexes. For the first time we (i) describe the organisation of the chorus formed by aggregating males, (ii) analysed the physical characteristics of the calling song, and (iii) used playback experiments of natural, modified, and allospecific signals to investigate the signal-recognition pr...

Adults provisioning dependent young are in conflict with their partners, who would prefer a greater level of effort, and with their offspring, who would prefer a greater supply of food. To what extent, then should adults negotiate their provisioning behaviour with other family members? We used experimental manipulations of brood size, and targeted playback of begging calls to determine the exte...

Species distribution models (SDMs) are a key tool for biogeography and climate change research, although current approaches have some significant drawbacks. The use of species occurrence constrains predictions correlative models, while there is general lack eco-physiological data to develop mechanistic models. Passive acoustic monitoring an emerging technique in ecology that may help overcome t...

In this paper, we proposed a new region extraction method using chroma key with a two-tone checker pattern background. This method solves the problem in conventional chroma key techniques that foreground objects become transparent if they have the same color with the background. The method utilizes the adjacency condition between two-tone regions of the background and the geometrical informatio...

This note reports the combined results of several initiatives in creating and surveying complete suites of endgame tables (EGTs) to the Depth to Mate (DTM) and Depth to Conversion (DTC) metrics. Data on percentage results, maximals and mutual zugzwangs, mzugs, has been filed and made available on the web, as have the DTM EGTs.

We give a very simple mathematical construction of the infinitesimals needed in understanding some simple go endgames as shown in book [1].
