Resumo. A partir de coletas realizadas com armadilhas Malaise em três fragmentos de Caatinga com diferentes níveis de degradação antrópica localizados em Jequié, Bahia, entre abril de 2005 e julho de 2007 foram obtidos 1.087 exemplares de Ichneumonidae, de 17 subfamílias. Constatou-se que ambiente com maior número de exemplares coletados foi o Remanescente de Caatinga (RC) (494 exemplares/45,4% do total), seguido por Agroecossistemas (AE) (399/36,8%) e Borda do Pasto (BP) (194/17,8%). Cremastinae e Cryptinae foram as subfamílias mais numerosas nas áreas estudadas e, conjuntamente, representaram 50,6% do material coletado. A diversidade de subfamílias foi bastante semelhante nas áreas amostradas. Como resultados deste estudo 18 subfamílias e 36 gêneros de Ichneumonidae tem ocorrência registrada para o bioma Caatinga dentre os quais oito subfamílias e 23 gêneros de Ichneumonidae foram registradas para o estado da Bahia. Duas espécies foram identificadas, Neotheronia lineata (Fabricius) (Pimplinae) e Joppocryptus occiputalis (Cresson) (novo registro para Bahia), entretanto, apesar dos esforços, são necessários mais estudos para a melhor compreensão da diversidade dos Ichneumonidae da Caatinga.Fauna of Ichneumonidae (Hymenoptera: Ichneumonoidea) in Caatinga areas of Southwestern Bahia, BrazilAbstract. Between April 2005 and July 2007, 1,087 specimens of Ichneumonidae from 17 subfamilies were obtained from samples performed with Malaise traps in three Caatinga fragments with different levels of anthropogenic degradation located in Jequié, Bahia, Brazil. It was found that the environment with the largest number of specimens collected was the Caatinga Remnant (CR) (494 specimens / 45.4% of the total), followed by Agroecosystems (AE) (399 / 36.8%) and Pasture Border ( PB) (194 / 17.8%). Cremastinae and Cryptinae were the most numerous subfamilies in the studied areas and together represented 50.6% of the collected material. The diversity of subfamilies was quite similar in the sampled areas. As a result of this study 18 subfamilies and 36 genera of Ichneumonidae have been recorded for the Caatinga biome among which eight subfamilies and 24 genera of Ichneumonidae were recorded for the state of Bahia. Two species were identified, Neotheronia lineata (Fabricius) (Pimplinae) and Joppocryptus occiputalis (Cresson) (new record for Bahia). However, despite efforts, further studies are needed to better understand the diversity of Ichneumonidae fauna in Caatinga biome.

Published: December 2019

Este estudo buscou identificar conhecimentos e práticas de pais de crianças de 6 a 12 meses de idade, sobre alimentação complementar e fatores que influenciam seu comportamento. Adotou-se o referencial teórico-metodológico da Teoria do Comportamento Planejado e optou-se por uma abordagem qualitativa e exploratória através de duas técnicas: grupo focal com mães e entrevistas em profundidade com pais, frequentadores de um serviço público de saúde e de uma clínica de pediatria privada. Do material empírico advindo dos relatos gravados e transcritos, por meio da análise de conteúdo, identificaram-se as categorias: Crenças, opiniões e atitudes, reorganizadas de acordo com suas relações com as recomendações do Ministério da Saúde incluídas no Guia Alimentar Para Crianças Menores de 2 anos; Influências formais e informais sobre as práticas de alimentação complementar; e Papel dos fatores socioeconômicos. Concluiu-se que os comportamentos dos pais são resultado da interação complexa entre suas crenças, pressões sociais e a percepção sobre sua competência para alimentar seus filhos, e que os dilemas e dúvidas são de toda ordem e independem da realidade sociocultural. O pediatra e outros profissionais da saúde perdem espaço para as influências informais que afetam diretamente as práticas de alimentação das crianças. Apontou-se a necessidade de prover orientações sobre alimentação complementar contextualizadas à realidade dos pais e que a internet seja utilizada por fontes confiáveis para disseminação do conhecimento.

External serrodyne modulation for the suppression of low-frequency noise in quadrature interferometry
Authors: Michaud-Belleau Vincent , Charlet Mark , Tourigny-Plante Alex , Deschênes Jean-Daniel , Genest Jérôme 
Published: December 2019

In interferometry, reaching a high signal-to-noise ratio at low frequencies can be challenging when the additive noise is nonstationary. Although this problem is typically solved by inserting a frequency shifter into one of the arms, in some cases, the interferometer cannot or should not be modified in this way. This Letter presents an alternative solution, based on external serrodyne frequency modulation, which is comparable to the typical approach in terms of complexity and performance yet does not require the modification of a passive interferometer. We demonstrate a prototype that achieves frequency shifting at 500 kHz with 89% power efficiency, leading to the wideband suppression of low-frequency additive noise by more than 19 dB. This enables a fully passive measurement of the thermoconductive noise of a 100 m single-mode fiber.
Fast peak-tracking method for FBG reflection spectrum and nonlinear error compensation

Published: December 2019

A universal method is proposed for fast tracking the peak wavelength of a fiber Bragg grating (FBG) reflection spectrum, which is the essential procedure of most FBG interrogators. Assuming the FBG reflection spectrum is sampled uniformly, we decompose the Moore–Penrose of the coefficient matrix into a formula that only contains a division and a dozen additions and multiplications; thereby, the cost of computation can be greatly reduced. Based on the analysis of the characteristics of the error introduced by the spectrum’s nonlinearity, we found and defined an error associated with the distance between the sampled peak and actual peak, and the compensating method for the error is also given. After compensation, the proposed method can speed up the tracking process 10 times or more without sacrificing the accuracy. An economical FBG interrogator with a commercial field programmable gate array (FPGA) and a microspectrometer was built up to verify the method, which was able to achieve a measurement frequency of 17 kHz.

Published: December 2019

AbstractDamage in biological neuronal networks triggers a complex functional reorganization whose mechanisms are still poorly understood. To delineate this reorganization process, here we investigate the functional alterations ofin vitrorat cortical circuits following localized laser ablation. The analysis of the functional network configuration before and after ablation allowed us to quantify the extent of functional alterations and the characteristic spatial and temporal scales along recovery. We observed that damage precipitated a fast rerouting of information flow that restored network’s communicability in about 15 min. Functional restoration was led by the immediate neighbors around trauma but was orchestrated by the entire network. Ourin vitrosetup exposes the ability of neuronal circuits to articulate fast responses to acute damage, and may serve as a proxy to devise recovery strategies in actual brain circuits. Moreover, this biological setup can become a benchmark to empirically test network theories about the spontaneous recovery in dynamical networks.
Task-Related Sensorimotor Adjustments Increase the Sensory Range in Electrolocation
Authors: Pedraja Federico , Hofmann Volker , Goulet Julie , Engelmann Jacob 
Published: December 2019

Perception and motor control traditionally are studied separately. However, motor activity can serve as a scaffold to shape the sensory flow. This tight link between motor actions and sensing is particularly evident in active sensory systems. Here, we investigate how the weakly electric mormyrid fishGnathonemus petersiiof undetermined sex structure their sensing and motor behavior while learning a perceptual task. We find systematic adjustments of the motor behavior that correlate with an increased performance. Using a model to compute the electrosensory input, we show that these behavioral adjustments improve the sensory input. As we find low neuronal detection thresholds at the level of medullary electrosensory neurons, it seems that the behavior-driven improvements of the sensory input are highly suitable to overcome the sensory limitations, thereby increasing the sensory range. Our results show that motor control is an active component of sensory learning, demonstrating that a detailed understanding of contribution of motor actions to sensing is needed to understand even seemingly simple behaviors.SIGNIFICANCE STATEMENTMotor-guided sensation and perception are intertwined, with motor behavior serving as a scaffold to shape the sensory input. We characterized how the weakly electric mormyrid fishGnathonemus petersii, as it learns a perceptual task, restructures its sensorimotor behavior. We find that systematic adjustments of the motor behavior correlate with increased performance and a shift of the sensory attention of the animal. Analyzing the afferent electrosensory input shows that a significant gain in information results from these sensorimotor adjustments. Our results show that motor control can be an active component of sensory learning. Researching the sensory corollaries of motor control thus can be crucial to understand sensory sensation and perception under naturalistic conditions.

Information Value Measure for Optimization of Flexible Diagnosis Programs of Technical Objects
Authors: Kopkin Evgeniy , Kobzarev Igor 
Published: December 2019

Existing methods of calculating of the value of diagnostic information circulating in the automated systems of monitoring of technical condition of objects do not take into account "losses" ("gains") resulting from making “wrong” decisions when identifying this state. The purpose of the work is to develop an algorithm that allows to solve the problem of recognizing the technical state of the object being analyzed by means of dynamic programming, the value of the diagnostic information as an optimized indicator being used. The solution to the optimization problem of a diagnostic procedure is based on the use of a measure of the information value proposed by R. L. Stratonovich. It is modified according to the subject area of the technical diagnostics and in the case when the diagnostic features presented in the form of intervals on the real numerical axis are used. The maximum value of the diagnostic information is achieved by minimizing the average "losses" (maximizing the average "gains") obtained when performing tests of diagnostic signs in the process of recognizing the technical condition of an object. To solve the problem, a recurrent expression possessing a scientific novelty has been proposed. It allows to calculate the value of the information obtained when performing tests of diagnostic signs in each of the analyzed information states of the diagnostic process. In the process of the diagnostics program implementation when recognizing the technical condition of the object both “losses” and “winnings” are possible. The difference between their a priori and a posteriori means values characterizes the value of the diagnostic information numerically. The magnitude of the information value indication depends on the probabilities of the results of the diagnostic signs checks and is proportional to the difference between the a posteriori and a priori probabilities of achieving the diagnostic goal. By using the proposed solution, it is possible to synthesize the flexible diagnostics program that is optimal according to the maximum value of diagnostic information in the form of a oriented graph or sets of tests in proper sequence of their execution. This is necessary in order to recognize the specific technical state in which the object is located. The implementation of the algorithm developed is possible in the software and algorithmic support of the automated systems for monitoring the state of complex technical objects.
Calculation and Research of Space-Temporal Characteristics of Attack Abrases of Asteroids by Orbital Means
Authors: Minakov Evgeniy , Sokolov Boris , Shaldaev Sergey , Aleksandrov Maksim 
Published: December 2019

A development of work to combat the asteroid hazard requires construction and study of areas of outer space in which moving spacecraft-interceptors can affect asteroids. In this paper, such areas are called attack lines, the spatio-temporal characteristics of which depend on the parameters of the asteroid’s orbits and the phase coordinates of the nodal points. At these points the trajectory intersects the asteroids and the orbital planes of the spacecraft-interceptors. In the case of the impact of spacecraft-interceptors on asteroids at nodal points, the study of the spatio-temporal characteristics of the lines of attack, taking into account restrictions on the relative speeds between asteroids and spacecraft-interceptors, is of particular importance. Building and analyzing the corresponding zones of reverse reach are suggested.
In the article, the developed models include a simulation model, using which random angles between the projections of the velocity vectors of asteroids on a plane of the orbits of spacecraft-interceptors and the current directions on the hodographs of their velocity vectors at nodal points, as well as an analytical model for estimating the spatio-temporal characteristics of boundaries are simulated attacks of asteroids, including: the radii of their external and internal boundaries for certain values of the latitude arguments and arrival time of spacecraft-interceptors at modal points.
Testing these models and the corresponding characteristics of the attack lines were carries out during computational experiments on two cyclic modeling of the angles between the projections of the velocity vectors of asteroids on the plane of the orbits of interceptor spacecraft and the current directions on the hodographs of their velocity vectors at nodal points. The results obtained made it possible to verify and validate the developed models, on the basis of which a conclusion was drawn about the required degree of their applicability. In the paper also a procedure for estimating the parameters of attack lines, depending on the values of the arguments of the latitudes of interceptor spacecraft and their altitudes above the Earth's surface is proposed. At the same time, an approach is substantiated for estimating the spatio-temporal characteristics of the boundaries of attack of asteroids by spacecraft-interceptors for any inside the planar parameters of their orbits.
Analytical-Numerical Calculation Algorithm of Algebraic Equations Roots with Specified Limits of Errors
Authors: Bychkov Yuri , Solovyeva Elena , Scherbakov Sergei 
Published: December 2019

This paper proposes an algorithm for calculating approximate values of roots of algebraic equations with a specified limit of absolute errors. A mathematical basis of the algorithm is an analytical-numerical method of solving nonlinear integral-differential equations with non-stationary coefficients. The analytical-numerical method belongs to the class of one-step continuous methods of variable order with an adaptive procedure for choosing a calculation step, a formalized estimate of the error of the performed calculations at each step and the error accumulated during the calculation. The proposed algorithm for calculating the approximate values of the roots of an algebraic equation with specified limit absolute errors consists of two stages. The results of the first stage are numerical intervals containing the unknown exact values of the roots of the algebraic equation. At the second stage, the approximate values of these roots with the specified limit absolute errors are calculated. As an example of the use of the proposed algorithm, defining the roots of the fifth-order algebraic equation with three different values of the limiting absolute error is presented.
The obtained results allow drawing the following conclusions. The proposed algorithm enables to select numeric intervals that contain unknown exact values of the roots. Knowledge of these intervals facilitates the calculation of the approximate root values under any specified limiting absolute error. The algorithm efficiency, i.e., the guarantee of achieving the goal, does not depend on the choice of initial conditions. The algorithm is not iterative, so the number of calculation steps required for extracting a numerical interval containing an unknown exact value of any root of an algebraic equation is always restricted. The algorithm of determining a certain root of the algebraic equation is computationally completely autonomous.
