Modeling Metaphysics: The Rise of Simulation and the Reversal of Platonism
2019
Philosophical reflection on and around Modeling and Simulation (M&S) is often focused on the ethical and epistemological implications of empirical findings or innovative methods within the field. In this paper I highlight some of the metaphysical implications of developments within M&S. I argue that the rise of simulation within and across scientific disciplines is accelerating the reversal of Platonism, whose emphasis on transcendence and reliance on hierarchical, static categories has dominated western philosophy for over two millennia. The success of M&S methodologies opens up new conceptual space for articulating a metaphysics of immanence that may provide a more adequate basis for unde…
Microwear textures associated with experimental near-natural diets suggest that seeds and hard insect body parts cause high enamel surface complexity…
2022
In mammals, complex dental microwear textures (DMT) representing differently sized and shaped enamel lesions overlaying each other have traditionally been associated with the seeds and kernels in frugivorous diets, as well as with sclerotized insect cuticles. Recently, this notion has been challenged by field observations as well as in vitro experimental data. It remains unclear to what extent each food item contributes to the complexity level and is reflected by the surface texture of the respective tooth position along the molar tooth row. To clarify the potential of seeds and other abrasive dietary items to cause complex microwear textures, we conducted a controlled feeding experiment wi…

El sujeto en Psicoterapia Cognitiva
2015
En este trabajo se reflexiona sobre el tipo de sujetos implícitos en psicoterapia cognitiva. El modelo cognitivo de Beck, al que podemos considerar como un modelo racionalista y modernista, ejemplificará estos sujetos. En primer lugar, debemos situar a la terapia cognitiva en un contexto histórico y relacionarla con un sujeto caracterizado por poseer racionalidad y la habilidad para observar y detectar cogniciones, emociones y conductas. Este trabajo desarrolla todo ello introduciendo tres tipos principales de sujetos. El primero es el sujeto introspectivo y consciente, que es capaz de observar lo que pasa en su interior, tiene acceso libre y es consciente de su mundo cognitivo. El segundo,…
Synthesis and anti-HIV activity of 2,3-diaryl-1,3-thiazolidin-4-(thi)one derivatives.
2002
Several 2,3-diaryl-1,3-thiazolidine-4-thione derivatives and 2,3-diaryl-1,3-thiazolidin-4-ones bearing a methyl group at C-5 position have been synthesized and tested as anti-HIV agents. The results of the in vitro tests showed that some of them proved to be effective inhibitors of HIV-1 replication.

Primary roots (radicles) represent the first visible developmental stages of the plant and are crucial for nutrient supply and the integration of environmental signals. Few studies have analyzed primary roots at a molecular level, and were mostly limited to Arabidopsis. Here we study the primary root transcriptomes of standard type, heterozygous columnar and homozygous columnar apple (Malus x domestica) by RNA-Seq and quantitative real-time PCR. The columnar growth habit is characterized by a stunted main axis and the development of short fruit spurs instead of long lateral branches. This compact growth possesses economic potential because it allows high density planting and mechanical harv…
Satellite Observations of the Contrasting Response of Trees and Grasses to Variations in Water Availability
2019
Interannual variations in ecosystem primary productivity are dominated by water availability. Until recently, characterizing the photosynthetic response of different ecosystems to soil moisture anomalies was hampered by observational limitations. Here, we use a number of satellite-based proxies for productivity, including spectral indices, sun-induced chlorophyll fluorescence, and data-driven estimates of gross primary production, to reevaluate the relationship between terrestrial photosynthesis and water. In contrast to nonwoody vegetation, we find a resilience of forested ecosystems to reduced soil moisture. Sun-induced chlorophyll fluorescence and data-driven gross primary production ind…
Errors and uncertainties introduced by a regional climate model in climate impact assessments: example of crop yield simulations in West Africa
2015
16 pages; International audience; The challenge of estimating the potential impacts of climate change has led to an increasing use of dynamical downscaling to produce fine spatial-scale climate projections for impact assessments. In this work, we analyze if and to what extent the bias in the simulated crop yield can be reduced by using the Weather Research and Forecasting (WRF) regional climate model to downscale ERA-Interim (European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis) rainfall and radiation data. Then, we evaluate the uncertainties resulting from both the choice of the physical parameterizations of the WRF model and its internal variability. Impact assessments w…
TheMedicago truncatulahypermycorrhizal B9 mutant displays an altered response to phosphate and is more susceptible toAphanomyces euteiches
2014
Inorganic phosphate (Pi) plays a key role in the development of arbuscular mycorrhizal (AM) symbiosis, which is favoured when Pi is limiting in the environment. We have characterized the Medicago truncatula hypermycorrhizal B9 mutant for its response to limiting (P/10) and replete (P2) Pi. On P2, mycorrhization was significantly higher in B9 plants than in wild-type (WT). The B9 mutant displayed hallmarks of Pi-limited plants, including higher levels of anthocyanins and lower concentrations of Pi in shoots than WT plants. Transcriptome analyses of roots of WT and B9 plants cultivated on P2 or on P/10 confirmed the Pi-limited profile of the mutant on P2 and highlighted its altered response t…
