1. Multi-Step-Ahead Spectrum Prediction for Cognitive Radio in Fading Scenarios
Abstract This paper analyzes multi-step-ahead spectrum prediction for Cognitive Radio (CR) systems using several future states. A slot-based scenario is used, and prediction is based on the Support Vector Machine (SVM) algorithm. The aim is to determine whether multi-step-ahead spectrum prediction has gains in terms of reduced channel-switching and increased

2. Chemical control of leaf-cutting ants: how do workers disperse toxic bait fragments onto fungus garden?
ABSTRACT Leaf-cutting ants are controlled with toxic baits. For the method’s greater efficiency, the baits must be distributed and processed by workers during fungus cultivation. To test hypotheses whether the mode of action of the active ingredients, which blocks the sodium channels and interrupts the production of ATP in the mitochondria, interferes with

3. CPI Exchange Rate Pass-Through Decomposition and Distribution Margins: The Case of Brazil versus Advanced Economies
Abstract We analyze the channels through which the Exchange rate affects final consumer prices. We compare advanced countries with one emerging economy, Brazil, to determine the corresponding exchange rate pass-through and its channels. A key aspect to the exchange rate pass-through is the relative importance of tradables in the consumption basket as well as

4. Renforcer, Renouer et Étendre les Liens: l’Odin Teatret à Cuba et en Uruguay au XXIe siècle
Resumo: O Odin Teatret, fundado em Oslo em 1964 e estabelecido na Dinamarca desde 1966, começou a tecer relações importantes com artistas latino-americanos a partir da segunda metade dos anos 1970, sobretudo durante suas diversas turnês além-mar (de 1976 até os dias de hoje). No artigo, através de dois estudos de caso (as turnês do Odin em Cuba, em 2

5. Plurality of governance on cattle ranches: case studies in Brazil
ABSTRACT The present article investigated the plural forms of governance that have been adopted in buying and selling transactions by cattle ranches with differentiated markets. In addition, it proposes to describe and explain which determinants influence this plurality, based on the theoretical principles of transaction cost economics. The analysis was base

6. An Investigation on the Deformation Heating in Billet and Die During Equal-Channel Angular Pressing and High-Pressure Torsion
This work aims to investigate the temperature rise in Aluminum alloy 6061 due to deformation heating in equal channel angular pressing (ECAP) and high-pressure torsion (HPT) processes using finite element method. The roles of various parameters are investigated and the heating of ECAP die due to billet deformation is included in the simulations. The results

7. Dysfunctional Hyperpolarization-Activated Cyclic Nucleotide-gated Ion Channels in Cardiac Diseases
Abstract Hyperpolarization-activated cyclic nucleotide-gated (HCN) channels are reverse voltage-dependent, and their activation depends on the hyperpolarization of the membrane and may be directly or indirectly regulated by the cyclic adenosine monophosphate (cAMP) or other signal-transduction cascades. The distribution, quantity and activation states of HCN

8. Changes in cortical bone channels network and osteocyte organization after the use of zoledronic acid
Objective The aim of this study was to evaluate the effects of zoledronic acid (ZA) on the cortical bone channels network (CBCN) and osteocyte organization in relation to the bone channels. Materials and methods Eighteen male Wistar rats were divided into control (CG) and test groups (TG). Twelve animals from TG received 3 ZA doses (7.5 µg/kg), and 6 an

9. Tidal effects on short-term mesozooplankton distribution in small channels of a temperate-turbid estuary, Southwestern Atlantic
Resumo A variação de curto prazo da distribuição do mesozooplâncton e das variáveis físico-químicas foi examinada em dois diferentes canais do Estuário de Bahia Blanca, Argentina, durante dois ciclos de maré. As medidas físico-químicas e a amostragem do zooplâncton foram realizadas em dois locais fixos durante aproximadamente 22-23 horas, com in

10. Large scale distribution of bacterial communities in the upper Paraná River floodplain
A bacterial community has a central role in nutrient cycle in aquatic habitats. Therefore, it is important to analyze how this community is distributed throughout different locations. Thirty-six different sites in the upper Paraná River floodplain were surveyed to determine the influence of environmental variable in bacterial community composition. The site

11. Microhardness and EBSD microstructure mapping in partially-pressed al and cu through 90º ECAP die
Equal-channel angular pressing (ECAP) is widely recognized as an effective method for processing ultrafine-grained and even nanostructured materials. Important details on processes occurring in the die intersections can be obtained by mapping the microhardness and EBSD microstructures in partially-pressed aluminum and copper through the 90º die of ECAP. Pre

12. Proposta de um método para a análise dos efeitos das atividades de marketing e alocação de recursos em um ambiente multicanal / A method for analyzing the effects of marketing activities and allocating marketing resources in a multichannel environment
A compreensão dos efeitos das atividades de marketing nas vendas de produtos de consumo em um ambiente multicanal é de fundamental importância para acadêmicos e executivos. As decisões sobre as variáveis controláveis de marketing para as marcas de consumo nos mercados considerados emergentes, como o Brasil, são desafiadoras porque, no contexto do var
