In this paper, we present a scheme to improve immune cloning selection algorithm. The improved algorithm, which is referred to as adaptive cloning selection algorithm (ACSA), is proposed and then applied to function optimization. At first, we present adaptive gene mutation which decides mutation probability of each code point (locus) based on the quality of antibodies and the number of evolution iterations. Secondly, we present an iteratively increasing method from one locus to the all ones, which can be used in function optimization. Then, the cloning selection process of evolution is divided into two-stages. The first step is to increase locus of antibodies. In the other one, the Baldwin effect learning operator is employed. And finally, an experiment is carried out to verify the theoretical analyses on several testing functions.

Program Description

Abstract Background Microsurgery fellowship applicants make decisions for future training based on information obtained from colleagues, mentors, and microsurgery fellowship program Websites (MFWs). In this study, we sought to evaluate the accessibility and quality of available information by microsurgery programs by analyzing the most commonly used web resources and social media outlets for applicants. Methods The San Francisco (SF) Match and American Society of Reconstructive Microsurgery Websites were queried in April 2020 for microsurgery fellowship programs (MFPs) participating in the SF Match. Twenty-two independent variables of information were assessed on MFWs based on previously published data. Social media presence was also assessed by querying Facebook, Instagram, and Twitter for official hospital, plastic surgery residency, and microsurgery fellowship accounts. Results All 24 MFWs participating in the SF Match had a webpage. Program description, faculty listing, operative volume, and eligibility requirements were listed for all programs (100%). The majority of MFWs listed affiliated hospitals (75%), provided a link to the fellowship application (66.7%), listed interview dates (66.7%), and highlighted research interests (50%). A minority of MFWs provided information on conference schedule (37.5%), current fellow listing (25%), previous fellow listing (16.67%), and positions held by previous fellows (8.33%). No MFWs (0%) presented information on selection process, or rotation schedule.All hospitals with an MFP had a Facebook page and nearly all had Instagram (83.3%) and Twitter accounts (95.8%). Plastic surgery residency programs at the same institution of an MFP had social media presence on Facebook (38.9%), Twitter (38.9%), and Instagram (66.7%). Only three MFPs had Facebook accounts (12.5%) and none had Instagram or Twitter accounts. Conclusion As the field of microsurgery continues to grow, the need for effective recruitment and training of microsurgeons continues to be essential. Overall, we conclude that both the accessibility and quality of information available to applicants are limited, which is a missed opportunity for recruitment.

According to the dominant view, the quality of individual scientific papers can be evaluated by the standard of the journal in which they are published. This paper attempts to demonstrate the limits of this view in the field of economics. According to our main findings, a publication frequently serves as a signal of high professional standards rather than as a source of information; referees and editors frequently reject good papers and accept bad ones; citation indices only partially balance the distortions deriving from the selection process; there are essential “entry costs” to the publication process. Moreover, financial interests of publishers may contradict scientific interests. As long as leading economists do not give voice to their dissatisfaction, there is no hope for any reform of the selection process.

A região Nordeste do Brasil vem sendo alvo de medidas do Estado a mais de um século, na tentativa de solucionar o problema da falta de água em época de secas. O Estado do Ceará, por sua vez, apresenta boa parte de seu território inserido no semiárido brasileiro, uma região caracterizada pelo clima seco, com poucas chuvas e elevada evapotranspiração. A problemática da água existe há bastante tempo, principalmente o acesso em quantidade e qualidade suficientes para atender a população. O presente trabalho tem como tema central a questão dos recursos hídricos, com enfoque no abastecimento humano do município de Cariré, localizado na região noroeste do Ceará. Nosso objetivo consiste em apresentar um panorama de como atualmente a população carireense tem acesso à água potável. A metodologia adotada constitui-se em duas etapas: na primeira, realizamos levantamento de material bibliográfico e a segunda diz respeito a parte prática realizada em saídas a campo. Segundo a ONU, a água é um bem comum e que deve ser de acesso a todos, é um direito humano. Nesta perspectiva, o gerenciamento adequado dos recursos hídricos é essencial para a manutenção da qualidade de vida. Palavras-chave: Recursos Hídricos; Abastecimento Humano; Cariré-Ce. ABSTRACTThe pnortheast region from Brazil has been subject of measures for more than a century in attempts to solve the problems lack of water in dry season. The state of Ceará has a good part of its territorial inserted in Brazilian semiarid, a region characterized by dry climate, short rains and high evapotranspiration. The water issue has existed for a long time, mainly in a sufficient access of quantity and quality to serve the population. Then, this article has as a central theme the water resources focusing on water supply of the Cariré localized at Northeast region from Ceará. Therefore the purpose of the paper is to present a study about how the Carire’s population has had access to potable water currently. The methodology adopted to this research consists of two stages: Firstly it was carried out a survey of bibliographical material and secondly it concerned the practical part carried out in the field trips. In accordance to United nations, water is a commom good and it has to be available to everyone, it is a human rights. In that sense, the proper management of water resources is essential to keep the quality of life.Key-words: Human supply; Water resources; Cariré – Ce. RÉSUMÉLa région du nord-est du Brésil est la cible de mesures prises par l’État depuis plus d’un siècle pour tenter de résoudre le problème de la pénurie d’eau en saison sèche. L’État du Ceará, en revanche, présente une bonne partie de son territoire inséré dans le semi-aride brésilien, région caractérisée par un climat sec, avec peu de pluies et une forte évapotranspiration. Le problème de l'eau existe depuis longtemps, principalement l'accès en quantité et qualité suffisantes pour satisfaire la population. Le travail actuel a pour thème central la question des ressources en eau, en mettant l'accent sur l'approvisionnement humain de la municipalité de Cariré, située dans la région nord-ouest du Ceará. Notre objectif est de présenter un aperçu de la façon dont la population carioca a actuellement accès à l’eau potable. La méthodologie adoptée comporte deux étapes: dans le premier, nous procédons à une enquête sur le matériel bibliographique et le second à la partie pratique réalisée lors des visites sur le terrain. Selon l'ONU, l'eau est un bien commun et doit être accessible à tous, c'est un droit humain. Dans cette perspective, la gestion adéquate des ressources en eau est essentielle au maintien de la qualité de la vie.Mots-clés: Ressources en eau; Approvisionnement humain; Cariré-Ce.

The Baldwin Effect

The Baldwin effect has been explicitly used by Pinker and Bloom as an explanation of the origins of language and the evolution of a language acquisition device. This article presents new simulations of an artificial life model for the evolution of compositional languages. It specifically addresses the role of cultural variation and of learning costs in the Baldwin effect for the evolution of language. Results show that when a high cost is associated with language learning, agents gradually assimilate in their genome some explicit features (e.g., lexical properties) of the specific language they are exposed to. When the structure of the language is allowed to vary through cultural transmission, Baldwinian processes cause, instead, the assimilation of a predisposition to learn, rather than any structural properties associated with a specific language. The analysis of the mechanisms underlying such a predisposition in terms of categorical perception supports Deacon's hypothesis regarding the Baldwinian inheritance of general underlying cognitive capabilities that serve language acquisition. This is in opposition to the thesis that argues for assimilation of structural properties needed for the specification of a full-blown language acquisition device.

Plant Seedlings

In agricultural production, weed removal is an important part of crop cultivation, but inevitably, other plants compete with crops for nutrients. Only by identifying and removing weeds can the quality of the harvest be guaranteed. Therefore, the distinction between weeds and crops is particularly important. Recently, deep learning technology has also been applied to the field of botany, and achieved good results. Convolutional neural networks are widely used in deep learning because of their excellent classification effects. The purpose of this article is to find a new method of plant seedling classification. This method includes two stages: image segmentation and image classification. The first stage is to use the improved U-Net to segment the dataset, and the second stage is to use six classification networks to classify the seedlings of the segmented dataset. The dataset used for the experiment contained 12 different types of plants, namely, 3 crops and 9 weeds. The model was evaluated by the multi-class statistical analysis of accuracy, recall, precision, and F1-score. The results show that the two-stage classification method combining the improved U-Net segmentation network and the classification network was more conducive to the classification of plant seedlings, and the classification accuracy reaches 97.7%.
