Abstract:

SUMMARY Language and Development in Africa Development in Africa is often defined in technocratic terms that do not take language into account. Yet, the continent is beset by problems of development that are language-related. The integration of national languages and the full participation of all the population will greatly enhance development in Africa. Over the last three decades, dependency on superimposed international languages to achieve development has proven to be a failure. Instead of leading to national unity, this attitude has contributed to the socioeconomic and political instability of most African nations. The people of Africa are the ones who will make it, or fail to make it, a developed continent. It would be most unwise to force upon them foreign linguistic and cultural models divorced from local realities. RESUMO Lingvoj kaj evoluo en Afriko Evoluon en Afriko oni ofte difinas lau teknokrataj kriterioj, kiuj ne prenas en konsideron la lingvan dimension. Sed la kontinenton sieĝas evoluproblemoj lingvorilataj. La integrigo de naciaj lingvoj kaj la plena partopreno de la tuta logantaro multe fortigos evoluon en Afriko. Tra la pasintaj tri jardekoj, dependo je altruditaj internaciaj lingvoj por atingi evoluon montriĝis malsukcesa. Anstataŭ konduki al nacia unueco, tia aliro kontribuis al la sociekonomia kaj politika nestabileco de plej multaj afrikaj nacioj. La afrikanoj estas tiuj, kiuj igos, au ne igos, Afrikon evoluinta kontinento. Estus tre malsaĝe trudi al ili fremdajn lingvajn kaj kulturajn modelojn malkongruajn al lokaj realoj.

Abstract:

SUMMARY What Language Contact Models Can Result from Our Indian Research Experience? This paper is the result of a conference in Nice (1987) on Language Contact: What Models? We tried to reply to this question by proposing two models, namely: (1) language development, a model that allows us to measure development in terms of language vitality and (2) language contact, a more general model, which takes into account the broader social context. These two models derive from a survey carried out in India from 1982 to 1985 on the written languages of that country. The survey's object was primarily to provide the government with a detailed description of the functional role of each language in the social life of the country. But, in a secondary analysis, the survey provided a model of language development (see above), which enables us to calculate in quantitative terms the linguistic vitality of each language. This was done by analyzing the functional aspect of the social (institutional) dimension, by (1) domain and (2) institutional levels, on the one hand, and by (3) functions (frequency) and (4) products (quantity) on the other. The model of language contact also incorporates the vitality concept, but the perspective is much wider. It is rare to find only one language, so the model must take into consideration the functional interaction of all languages present and the resulting effects of this on vitality. Next, the total social environment and its importance must be measured through variables or groups of variables, which can also influence language vitality. This allows us to propose hypotheses on the importance of the language and social environments on changing vitality rates. The paper concludes by clearly placing the above research in the macro sphere (sociology of language) and considers the above inductive models based on hard data a useful way of approaching a theory of language in society, which has yet to be constructed. RESUMO Kiuj lingvokontaktaj modeloj povas rezulti el la esploraj spertoj en Hindio? Tiu ci verko rezultas el konferenco en Nico (1987) pri Lingva kontakto: Kiuj modeloj? Ni provis respondi tiun demandon per propono de du modeloj, nome: (l) modelo de lingva evoluo, kiu ebligas nin mezuri evoluon laŭ lingva vivanteco kaj (2) lingva kontakto, pli ĝenerala modelo, kiu prenas en konsideron la pli vastan socian kuntekston. La du modeloj fontas el enketo farita en Hindio inter 1982 kaj 1985 pri la tiulandaj skribitaj lingvoj. La ĉefa celo de la enketo estis liveri al la registaro detalan priskribon de la funkcia rolo de ĉiu lingvo en la socia vivo de la lando. Sed per dua analizo la enketo donis modelon de lingva evoluo (vidu ĉi-supre), kiu ebligas kvalitan kalkulon de la lingva vivanteco de ĉiu lingvo. Tion ni faris analizante la funkcian aspekton de la socia (insti-tucia) dimensio, laŭ (1) medio kaj (2) instituciaj niveloj, unuflanke, kaj laŭ (3) funkcioj (ofteco) kaj (4) produktoj (kvanto), aliflanke. La lingvokontakta modelo ankaŭ enhavas la koncepton de vivanteco, sed laŭ multe pli vasta perspektivo. Malofte oni trovas nur unu lingvon, kaj sekve la modelo devas preni en konsideron la funkcian interagon de ciuj ceestantaj lingvoj kaj la rezultajn efikojn de cio ci je vivanteco. Krome, oni devas mezuri la kompletan socian medion kaj ĝian gravecon per variecoj kaj variecogrupoj, kiuj ankaŭ povas influi lingvovivantecon. Tio ebligas proponi hipotezojn pri la graveco de la lingva kaj socia medioj je ŝanĝiĝantaj niveloj de vivanteco. La verko finiĝas lokante la ĉi-suprajn esplorojn en la makro-sferon (lingva sociologio) kaj konsideras la ĉi-suprajn induktajn modelojn, bazitajn je firmaj donitaĵoj, utila maniero aliri teorion de lingvo en socio, ankoraŭ konstruotan.

Abstract OBJECTIVES To compare device success and paravalvular leak rates of 3 new-generation transcatheter aortic valve replacement devices in patients with bicuspid aortic valve stenosis and to test their biomechanical performance in a computer-based simulation model of aortic root with increasing ellipticity. METHODS This retrospective multicentre study included 56 bicuspid aortic valve patients undergoing transcatheter aortic valve replacement with new-generation devices: Lotus/Lotus Edge (N = 15; 27%), Evolut-R (N = 20; 36%) and ACURATE neo (N = 21; 37%). Three virtual simulation models of aortic root with increasing index of eccentricity (0–0.25–0.5) were implemented. Stress distribution, stent–root contact area and paravalvular orifice area were computed. RESULTS Device success was achieved in 43/56 patients (77%) with comparable rates among Lotus (87%), Evolut-R (60%) and ACURATE neo (86%; P = 0.085). Moderate paravalvular leak rate was significantly lower in the Lotus group as compared to Evolut-R group (0% vs 30%; P = 0.027) and comparable to the ACURATE neo group (0% vs 10%; P = 0.33). By index of eccentricity = 0.5, Lotus showed a uniform and symmetric pattern of stress distribution with absent paravalvular orifice area, ACURATE neo showed a mild asymmetry with small paravalvular orifice area (1.1 mm2), whereas a severely asymmetric pattern was evident with Evolut-R, resulting in a large paravalvular orifice area (12.0 mm2). CONCLUSIONS Transcatheter aortic valve replacement in bicuspid aortic valve patients with new-generation devices showed comparable device success rates. Lotus showed moderate paravalvular leak rate comparable to that of ACURATE neo and significantly lower than Evolut-R. On simulation, Lotus and ACURATE neo showed optimal adaptability to elliptic anatomies as compared to Evolut-R.

Na arte contemporânea, percepções conflitantes da realidade promovem uma reviravolta no papel da razão na construção do real e da verdade. Nesse contexto, é possível considerar outros balizamentos para o estético e o político, desconstruindo a falsa noção de universalidade fundada em binaridades como: racionalidade e irracionalidade, civilizado e primitivo. O pensamento de autores como Isabelle Stenger, David Harvey, António Damásio, Ellen Dissanayake são considerados neste estudo na fundamentação de uma reflexão sobre a arte contemporânea e a crítica sobre o papel da ciência, tendo em perspectiva o contexto da trajetória histórica do imperialismo e da dominação dos países em desenvolvimento pelas grandes corporações. Assumem evidência, nesse cenário, o capitalismo em crise e o modelo evolutivo do evolon, como ferramenta para análise.

Abstract:

Abstract In molecular population genetics, adaptation is typically thought to occur via selective sweeps, where targets of selection have independent effects on the phenotype and rise to fixation, whereas in quantitative genetics, many loci contribute to the phenotype and subtle frequency changes occur at many loci during polygenic adaptation. The sweep model makes specific predictions about frequency changes of beneficial alleles and many test statistics have been developed to detect such selection signatures. Despite polygenic adaptation is probably the prevalent mode of adaptation, because of the traditional focus on the phenotype, we are lacking a solid understanding of the similarities and differences of selection signatures under the two models. Recent theoretical and empirical studies have shown that both selective sweep and polygenic adaptation models could result in a sweep-like genomic signature; therefore, additional criteria are needed to distinguish the two models. With replicated populations and time series data, experimental evolution studies have the potential to identify the underlying model of adaptation. Using the framework of experimental evolution, we performed computer simulations to study the pattern of selected alleles for two models: 1) adaptation of a trait via independent beneficial mutations that are conditioned for fixation, that is, selective sweep model and 2) trait optimum model (polygenic adaptation), that is adaptation of a quantitative trait under stabilizing selection after a sudden shift in trait optimum. We identify several distinct patterns of selective sweep and trait optimum models in populations of different sizes. These features could provide the foundation for development of quantitative approaches to differentiate the two models.

Abstract:

Research background: Research and measurement of sentiments, and the integration of methods for sentiment analysis in forecasting models or trading strategies for financial markets are gaining increasing attention at present. The theories that claim it is difficult to predict the individual investor’s decision also claim that individual investors cause market instability due to their irrationality. The existing instability increases the need for scientific research. Purpose of the article: This paper is dedicated to establishing a link between the individual investors’ behavior, which is expressed as sentiments, and the market dynamic, and is evaluated in the stock market. This article hypothesizes that the dynamics in the market is unequivocally related to the individual investor’s sentiments, and that this relationship occurs when the sentiments are expressed strongly and are unlimited. Methods: The research was carried out invoking the method of Evolino RNN-based prediction model. The data for the research from AAII (American Association of Individual Investors), an investor sentiment survey, were used. Stock indices and sentiments are forecasted separately before being combined as a single composition of distributions. Findings & Value added: The novelty of this paper is the prediction of sentiments of individual investors using an Evolino RNN-based prediction model. The results of this paper should be seen not only as the prediction of the connection and composition of investors’ sentiments and stock indices, but also as the research of the dynamic of individual investors’ sentiments and indices.

Abstract:

In this paper, we introduce the evolve-then-filter (EF) regularization method for reduced order modeling of convection-dominated stochastic systems. The standard Galerkin projection reduced order model (G-ROM) yield numerical oscillations in a convection-dominated regime. The evolve-then-filter reduced order model (EF-ROM) aims at the numerical stabilization of the standard G-ROM, which uses explicit ROM spatial filter to regularize various terms in the reduced order model (ROM). Our numerical results are based on a stochastic Burgers equation with linear multiplicative noise. The numerical result shows that the EF-ROM is significantly better than G-ROM.

Abstract:

Abstract Apparent biases in decision making by animals, including humans, seem to present an evolutionary puzzle, since one would expect decisions based on biased (unrealistic) information to be suboptimal. Although cognitive biases are hard to diagnose in real animals (Marshall et al., 2013b), we investigate Trivers’ proposal that individuals should self-deceive first in order to better deceive others (Trivers, 2011). Although this proposal has been scrutinized extensively (Bandura et al., 2011) it has not been formally modelled. We present the first model designed to investigate Trivers’ proposal. We introduce an extension to a recent model of the evolution of self-deception (Johnson and Fowler, 2011). In the extended model individuals make decisions by taking directly into account the benefits and costs of each outcome and by choosing the course of action that can be estimated as the best with the information available. It is shown that in certain circumstances self-deceiving decision-makers are the most evolutionarily successful, even when there is no deception between these. In a further extension of this model individuals additionally exhibit deception biases and Trivers’ premise (that effective deception is less physiologically costly with the aid of self-deception) is incorporated. It is shown that under Trivers’ hypothesis natural selection favors individuals that self-deceive as they deceive others.

Full text

Abstract:

In this paper, we put forth an evolve-then-correct reduced order modeling approach that combines intrusive and nonintrusive models to take hidden physical processes into account. Specifically, we split the underlying dynamics into known and unknown components. In the known part, we first utilize an intrusive Galerkin method projected on a set of basis functions obtained by proper orthogonal decomposition. We then present two variants of correction formula based on the assumption that the observed data are a manifestation of all relevant processes. The first method uses a standard least-squares regression with a quadratic approximation and requires solving a rank-deficient linear system, while the second approach employs a recurrent neural network emulator to account for the correction term. We further enhance our approach by using an orthonormality conforming basis interpolation approach on a Grassmannian manifold to address off-design conditions. The proposed framework is illustrated here with the application of two-dimensional co-rotating vortex simulations under modeling uncertainty. The results demonstrate highly accurate predictions underlining the effectiveness of the evolve-then-correct approach toward real-time simulations, where the full process model is not known a priori.

Abstract:

Abstract In 1991, Barton and Turelli developed recursions to describe the evolution of multilocus systems under arbitrary forms of selection. This article generalizes their approach to allow for arbitrary modes of inheritance, including diploidy, polyploidy, sex linkage, cytoplasmic inheritance, and genomic imprinting. The framework is also extended to allow for other deterministic evolutionary forces, including migration and mutation. Exact recursions that fully describe the state of the population are presented; these are implemented in a computer algebra package (available on the Web at http://helios.bto.ed.ac.uk/evolgen). Despite the generality of our framework, it can describe evolutionary dynamics exactly by just two equations. These recursions can be further simplified using a “quasi-linkage equilibrium” (QLE) approximation. We illustrate the methods by finding the effect of natural selection, sexual selection, mutation, and migration on the genetic composition of a population.

AbstractThermal oxidation of silicon is described as a three-component thermodynamic local process involving silicon, silicon oxide, and oxygen molecules. A simplified system of model equations is used to demonstrate the evoluton of the Si-SiO2 interface. For the one-dimensional case the equivalence with the model of Deal and Grove could be shown analytically. For that purpose effective interface coordinates have been introduced which establish the connection between the conventional concept of sharp interfaces and our "diffusive" interface, i.e., a transition region between pure silicon and pure silicon oxide.

Abstract:

Applications of the cellular Potts model to investigate cellular structures are becoming widely spread in the scientific literature. Despite its realism and generality, the standard Monte Carlo algorithm used to evolve this model in the scientific literature lacks computational efficiency. As an alternative we introduce the Random Walker algorithm that is a modified Monte Carlo procedure of simpler parallelization. We test it in cell sorting and foam coarsening simulations obtaining velocity increase factors of 10 and 3 times, respectively, in relation to the standard algorithm. The results obtained with these simulations are equivalent to those obtained with the standard algorithm.

Abstract:

Abstract The evolution of short repeated sequences by replication slippage under the assumption of selective neutrality is modeled using a linear birth and death process. The equilibrium distribution, the distribution of the life expectancy of a repeated sequence when the process starts from two repeats, the age distribution of repeats, the probability of obtaining two genes with i and j copies which diverged t generations ago and the conditional variance of copy number given the repeat number is more than one are computed. The distributions of life expectancy and age are shown to have long tails. Also the statistic which estimates the conditional variance is shown to have a large coefficient of variation. Using these theoretical results, we develop an approximate test of our model and analyze persistent repeated sequences found in the primate beta-globin gene region and Oenothera chloroplast DNA which are polymorphic within species. We found one sequence in Oenothera chloroplast DNA which does not fit to our neutral model.

Abstract:

Abstract Dendritic cell (DC) homeostasis in peripheral tissues reflect a balance between DC generation, migration, and death. The current model of DC ontogeny indicates that pre-cDCs are committed to become terminal conventional DCs (cDCs). Here, we report the unexpected finding that proliferating immunostimulatory CD11c+ MHC class II+ cDCs derived from pre-cDCs can lose their DC identity and generate progeny that exhibit morphologic, phenotypic, and functional characteristics of regulatory macrophages. DC-derived–macrophages (DC-d-Ms) potently suppress T-cell responses through the production of immunosuppressive molecules including nitric oxide, arginase, and IL-10. Relative deficiency of granulocyte-macrophage colony stimulating factor (GM-CSF) provided a permissive signal for DC-d-M generation. Using a transgenic mouse model that allows tracking of CD11c+ cells in vivo, we found that DC-d-M development occurs commonly in cancer, but not in lymphoid or nonlymphoid tissues under steady-state conditions. We propose that this developmental pathway serves as an alternative mechanism of regulating DC homeostasis during inflammatory processes.

Abstract:

The concept of self-protection, a capability of an organism to protect itself from exogenous attacks, is introduced into the design of artificial evolutionary systems as a possible method to create and maintain diversity in the population. Three different mechanisms of self-protection are considered and implemented on a cellular-automaton-based evolutionary system, the evoloop. Simulation results imply a positive effect of those mechanisms on diversity maintenance, especially when the self-protection is moderate so that it conserves both the attacker and the attacked. This letter briefly reports the models and the simulation results obtained using those models.

Abstract:

La psicoterapia es un campo de experiencia “extra-ordinaria”, en el cual el psicoterapeuta debe tener la habilidad de tratar con emociones, con el objetivo de mejorar las habilidades del paciente de regular sus propias emociones. Esto está más allá de la experiencia ordinaria, porque en este tipo de setting, no sólo los pacientes recuerdas sus experiencias emocionales del pasado, exigiendo empatía por parte del terapeuta, sino también evocan en él, continuamente y frecuentemente, reacciones emocionales, especialmente en sesiones en las cuales las dos partes están profundamente implicadas. En esta forma de relación profunda, algo pasa que no sólo es cognitivo, sino también kinético y somático, especialmente en la psicoterapia con niños y adolescentes. Esta forma de sessión terapéutica es una preciosa ocasión para aprender a expresar, comprender y tratar con las emociones. Este artículo presenta algunas teorías sobre emociones, que explican de diferente manera los factores que evocan emociones en la vida cotidiana y qué procesos están implicados. La descripción de sesiones terapéuticas con tres preadolescentes intenta mostrar como el concepto del terapeuta sobre el modelo específico de las emociones afecta su relación con el paciente y como aumenta la competencia emocional de éste.

Full text

Abstract:

Abstract A recently duplicated gene can either fix a null allele (becoming a pseudogene) or fix an (advantageous) allele giving a slightly different function, starting it on the road to evolving a new function. Here we examine the relative probabilities of these two events under a simple model. Null alleles are assumed to be neutral; linkage effects are ignored, as are unequal crossing over and gene conversion. These assumptions likely make our results underestimates for the probability that an advantageous allele is fixed first. When new advantageous mutations are additive with selection coefficient s and the ratio of advantageous to null mutations is rho, the probability an advantageous allele is fixed first is ([1 - e-s]/[rho S] + 1)-1, where S = 4Nes with Ne the effective population size. The probability that a duplicate locus becomes a pseudogene, as opposed to evolving a new gene function, is high unless rhoS > 1. However, even if advantageous mutations are very rare relative to null mutations, for sufficiently large populations rhoS > 1 and new gene function, rather than pseudogene formation, is the expected fate of most duplicated genes.

Abstract:

Swarming behaviours in animals have been extensively studied owing to their implications for the evolution of cooperation, social cognition and predator–prey dynamics. An important goal of these studies is discerning which evolutionary pressures favour the formation of swarms. One hypothesis is that swarms arise because the presence of multiple moving prey in swarms causes confusion for attacking predators, but it remains unclear how important this selective force is. Using an evolutionary model of a predator–prey system, we show that predator confusion provides a sufficient selection pressure to evolve swarming behaviour in prey. Furthermore, we demonstrate that the evolutionary effect of predator confusion on prey could in turn exert pressure on the structure of the predator's visual field, favouring the frontally oriented, high-resolution visual systems commonly observed in predators that feed on swarming animals. Finally, we provide evidence that when prey evolve swarming in response to predator confusion, there is a change in the shape of the functional response curve describing the predator's consumption rate as prey density increases. Thus, we show that a relatively simple perceptual constraint—predator confusion—could have pervasive evolutionary effects on prey behaviour, predator sensory mechanisms and the ecological interactions between predators and prey.

Abstract:

Lung injury was the common and serious complication of sepsis, a systemic inflammatory response syndrome caused by severe infections. Chinese medicine had unique advantages in attenuating inflammatory response, such as Zuojinfang (ZJF). ZJF was a classical compound herb formula composed of Coptidis Rhizoma and Euodiae Fructus in a ratio of 6 : 1. In this paper, 15 ingredients in ZJF were identified and 8 of them absorbed into rat’s serum were quantified by HPLC-MS/MS. Subsequently, sepsis-induced lung injury model was replicated in rats by cecal ligation and puncture. 60 SD rats were randomly divided into 6 groups ( n = 10 ): control group (CON), sham group (Sham), model group (MOD), ZJF low-dose group (ZJF-L), ZJF high-dose group (ZJF-H), and prednisolone group (PNSL). Within the next 24 h, the levels of inflammatory factors, correlation between active ingredients and inflammatory cytokines, the pathological changes of lung tissue, and protein expression of the JAK1/STAT3 signaling pathways were analyzed one by one. Finally, the concentration order of components absorbed in rat serum was berberine > palmatine > jatrorrhizine > coptisine > evodin > chlorogenic acid > evodiamine. Compared with the MOD group, the TNF-α, IL-6, and IFN-γ in the ZJF-H group were significantly reduced ( p < 0.05 ). Moreover, the TNF-α decreased significantly accompanied by the increase of berberine, chlorogenic acid, jatrorrhizine, palmatine, evodin, and evodiamine in serum (negative correlation, p < 0.05 ). Compared with the MOD, the area of lung injury, the expressions of JAK1, p-JAK1, STAT3, and p-STAT3 were significantly decreased under the treatment of ZJF ( p < 0.05 ). Therefore, downregulating the JAK1/STAT3 signaling pathways was a potential avenue of ZJF in reversing lung injury induced by sepsis.

Abstract:

Abstract A simple model is developed to evolve daily ground temperatures from surface air temperatures (SATs) in snow-dominated areas. Ground surface temperatures (GSTs) are calculated by propagating the daily SAT through the snowpack, and attenuating the signal amplitude. Subsequent subsurface heat transfer is then modeled using the analytical solution of the one-dimensional heat conduction equation. The thermal impacts of nonconductive heat transfer processes and seasonal freeze thaw are implicitly represented by the time-dependent apparent thermal diffusivity of the subsurface. The model is tested in four snow-dominated regions: Barrow, Council, Ivotuk (all in Alaska) and Reynolds Creek Experimental Watershed (in Idaho). The model captures the seasonal evolution of the ground temperature at all sites. The model demonstrates the feasibility of simulating subsurface temperatures using only air temperature and snow depth.
