Slime mould computes planar shapes [PDF]

International Journal of Bio-Inspired Computation 2012 - Vol. 4, No.3 pp. 149 - 154, 2011
Computing a polygon defining a set of planar points is a classical problem of modern computational geometry. In laboratory experiments we demonstrate that a concave hull, a connected alpha-shape without holes, of a finite planar set is approximated by slime mould Physarum polycephalum.

Effective Yet Ephemeral Propaganda Defense: There Needs to Be More than One-Shot Inoculation to Enhance Critical Thinking [PDF]

arXiv
In today's media landscape, propaganda distribution has a significant impact on society. It sows confusion, undermines democratic processes, and leads to increasingly difficult decision-making for news readers. We investigate the lasting effect on critical thinking and propaganda awareness on them when using a propaganda detection and contextualization

On the Benefits of Inoculation, an Example in Train Scheduling [PDF]

Dans GECCO-2006 (2006), 2006
The local reconstruction of a railway schedule following a small perturbation of the traffic, seeking minimization of the total accumulated delay, is a very difficult and tightly constrained combinatorial problem. Notoriously enough, the railway company's public image degrades proportionally to the amount of daily delays, and the same goes for its ...

On the Windfall and Price of Friendship: Inoculation Strategies on Social Networks [PDF]

arXiv, 2011
This article investigates selfish behavior in games where players are embedded in a social context. A framework is presented which allows us to measure the Windfall of Friendship, i.e., how much players benefit (compared to purely selfish environments) if they care about the welfare of their friends in the social network graph. As a case study, a virus

Fermentation Characteristics of Rice Crop Residue-Based Silage Treated by Epiphytic and Commercial LAB

Media Peternakan, 2012
Two experiments were conducted to investigate the effects of addition of lactic acid bacteria (LAB) inoculant from king grass and a commercial inoculant of L. plantarum on fermentation characteristics and nutrient digestibility of rice crop residue-based

Hyperspectral band selection using genetic algorithm and support vector machines for early identification of charcoal rot disease in soybean [PDF]

arXiv, 2017
Charcoal rot is a fungal disease that thrives in warm dry conditions and affects the yield of soybeans and other important agronomic crops worldwide. There is a need for robust, automatic and consistent early detection and quantification of disease symptoms which are important in breeding programs for the development of improved cultivars and in crop ...

Theoretical modeling of prion disease incubation [PDF]

arXiv, 2001
We present a theory for the laboratory and epidemiological data for incubation times in infectious prion diseases. The central feature of our model is that slow growth of misfolded protein-aggregates from small initial seeds controls the `latent' or `lag' phase, whereas aggregate-fissioning and subsequent spreading leads to an exponential growth or ...

Mitigation of Mombasa Grass ( Megathyrsus maximus ) Dependence on Nitrogen Fertilization as a Function of Inoculation with Azospirillum brasilense

Revista Brasileira de Ciência do Solo
Using biological inputs to improve the efficiency of nitrogen fertilizers represents an alternative for the cultivation of grasses in tropical regions.

Trans-Canada Slimeways: Slime mould imitates the Canadian transport network [PDF]

arXiv, 2011
Slime mould Physarum polycephalum builds up sophisticated networks to transport nutrients between distant part of its extended body. The slime mould's protoplasmic network is optimised for maximum coverage of nutrients yet minimum energy spent on transportation of the intra-cellular material. In laboratory experiments with P.

Improving QA Model Performance with Cartographic Inoculation [PDF]

arXiv
QA models are faced with complex and open-ended contextual reasoning problems, but can often learn well-performing solution heuristics by exploiting dataset-specific patterns in their training data. These patterns, or "dataset artifacts", reduce the model's ability to generalize to real-world QA problems.
