Differential rotation on the young solar analogue V889 Herculis

V889 Herculis is one of the brightest single early-G type stars, a young Sun, that is rotating fast enough (P_rot =1.337 days) for mapping its surface by Doppler Imaging. The 10 FOCES spectra collected between 13-16 Aug 2006 at Calar Alto Observatory allowed us to reconstruct one single Doppler image for two mapping lines. The FeI-6411 and CaI-6439 maps, in a good agreement, revealed an asymmetric polar cap and several weaker features at lower latitudes. Applying the sheared-image method with our Doppler reconstruction we perform an investigation to detect surface differential rotation (DR). The resulting DR parameter, deltaOmega/Omega~0.009 of solar type, is compared to previous studies which reported either much stronger shear or comparably weak DR, or just preferred rigid rotation. Theoretical aspects are also considered and discussed.Comment: 4 pages, 2 figure, 1 table; talk at the IAU Symposium 273 "Physics of Sun and Star Spots", Eds. D. P. Choudhary and K. G.

Individuality in Fish Behavior: Ecology and Comparative Psychology

This work is a brief review of a series of studies of the phenotypic organization and ecological significance of individual differences in fish behavior. The following species were studied: guppy Poecilia retuculata, lion-headed cichlid Steatocranus cassuarius, and the convict cichlid Archocentrus nigrofasciatum. We developed methods for the analysis of individual differences in fish behavior and studied their structure, development, and ecological and evolutionary significance

Rainfall-Runoff Relationships and flow forecasting, Ogun river Nigeria

An excess or a lack of rainfall are the major causes of most hydrological hazards, and the need for a systematic approach to river flow forecasting based on rainfall is imperative, especially in Nigeria. A study was carried out on three major gauging stations of the Ogun river basin to determine the rainfall-discharge relationship and model equations for use in the basin and similar basins. Stream flow and rainfall data for at least seven consecutive years for each station were collected and analyzed. The rainfall-runoff data were subjected to linear, exponential and higher order analysis. Stream flow data were also fitted to normal, log-normal and log-Pearson Type III distributions. The selection of the appropriate probability distribution model for each gauging station was based on graphical comparisons between observed and predicted flows and goodness-of-fit tests using chi-square and probability correlation coefficients. Results show that model equations with logarithmic and exponential relationships between rainfall and discharge gave better and more realistic prediction estimates and can be used for the basin. It was determined that the peak discharges occurred when the rainfall values were at their maximum, and a distinct relationship between the discharge and rainfall exists at each of the gauging stations

Language impairments in ALS/MND (Amyotrophic Lateral Sclerosis/Motor Neuron Disease)

Of Pisa, Italy c Corresponding author: Giancarlo Buoiano Via del Morello 8 Bargecchia I-55040 Corsanico (LU) email: [email protected] Language impairments in Amyotrophic Lateral Sclerosis/Motor Neuron Disease (ALS/MND) Abstract We review 6 papers on Motor Neuron Disease (MND) and language impairments. ALS/MND (Amyotrophic Lateral Sclerosis/MND) is an wide-ranging term used to cover several derangements of the motor neurons. ALS/MND brings to progressive degeneration of the motor neurons. The motor neurons control the muscles that consent us to move and act. Until some years ago, ALS/MND was thought not to affect language and higher-order cognitive functions, but at present it is acknowledged that about 3-5% of patients affected by ALS/MND show cognitive impairments. Up to date, it is not possible to establish whether this subgroup is affected by ALS/MND and Fronto-Temporal Dementia (FTD) or FTD/Aphasia syndrome or whether FTD/aphasia syndrome can be, in some cases, a consequence of ALS/MND. Furthermore, it is not clear whether MND/FTD syndrome brings to language breakdown or whether MND/Aphasia can be considered a self-standing syndrome. Lexical category-specific impairments affect more often than not verbs, while nouns appear to be by some means preserved. The verbs deficit is remarkable because it can place a new light on the link between actions, verbal and cognitive imagery, and ideomotor praxis. Language impairments detected in ALS/MND point largely to frontal and frontostriatal damages. Actually functional neuroimaging studies show reduced frontal activation. Alterations in Broca’s area, DorsoLateral PreFrontal Cortex (DLPFC) and fronto-striatal circuit have been all reported in ALS/MND: several functional studies link Broca’s area to syntactic processing and DLPFC to verbs production as well as language Short Term Memory (STM). A basic issue is the link between action and verbs and, as a result, between action syntax and speech syntax. This connection would be involved in the origin of language: it would be evolved passing from action to speech syntax. According to our point of view, verbs are pivotal in this system. In short, when actions are missing, verbs, ideomotor praxis and their neurocorrelates would deteriorate. A longitudinal study on the effect of massive motor derangement on the verb degeneration is at present carried out by our research group, so to date this is a working hypothesis waiting for further evidence. Keywords: ALS/MND, syntax, verbs, action, fronto-striatal circuit

The Self-Organization of Interaction Networks for Nature-Inspired Optimization

Over the last decade, significant progress has been made in understanding complex biological systems, however there have been few attempts at incorporating this knowledge into nature inspired optimization algorithms. In this paper, we present a first attempt at incorporating some of the basic structural properties of complex biological systems which are believed to be necessary preconditions for system qualities such as robustness. In particular, we focus on two important conditions missing in Evolutionary Algorithm populations; a self-organized definition of locality and interaction epistasis. We demonstrate that these two features, when combined, provide algorithm behaviors not observed in the canonical Evolutionary Algorithm or in Evolutionary Algorithms with structured populations such as the Cellular Genetic Algorithm. The most noticeable change in algorithm behavior is an unprecedented capacity for sustainable coexistence of genetically distinct individuals within a single population. This capacity for sustained genetic diversity is not imposed on the population but instead emerges as a natural consequence of the dynamics of the system
