Long-term acclimation of growth rates in the oligotrich freshwater ciliate Meseres corlissi

An inherent assumption in typicallaboratory investigations is that experimental conditions yield results that adequately characterize the ecophysiological performance in situ ofthe species under study. Recent evidence suggests that this approach is questionable for ciliates and other protists (LowE et al. 2005, WEISSE & RAMMER 2006). In particular, intraspecific variation in the temperature response and temperature adaptation within a nominal species have been documented for several planktonic ciliate species (WEISSE 2006). The temperature (T) response of 9 clones of Meseres corlissi, a globally distributed but rare freshwater ciliate, was investigated recently in our laboratory (WEISSE 2004, ÜÃCHTER & WEISSE 2006). The minimum temperature tolerated by the clones was positively related to the minimum temperature encountered in their natural habitat, suggesting that freshwater ciliates may be physiologically adapted to their respective climatic habitat. ÜÃCHTER & WEISSE (2006) concluded that the phenotypic differences observed were genetically fixed, because the ciliate clones had been kept under identical laboratory conditions over several hundred generations prior to beginning the experiments. This study investigated whether long-term ( over several months, i.e. more than several hundred generations) acclimation to laboratory conditions affects results obtained in typical growth-response experiments. We define acclimation as a reversible, physiological modification of a specific trait, such as temperature tolerance; acclimation is an example of phenotypic plasticity, which is different from genetically fixed adaptation to a specific habitat (DE MEESTER 1996, HuEY & BERRIGAN 1996). Another recent study with M. corlissi on the role of soi! in their life cycle (MüLLER et al. 2006) showed that, in contrast to a tropical strain from the Dominican Republic (WEISSE 2004), at least 2 of the Austrian clones require the addition of soi! extract (SE) for sustained optimal growth, and that SE controlled enand excystment of the latter. Most findings of M. corlissi have been reported from flood plains, meadows and other dry habitats that are periodically flooded and contain suspended soi! and dissolved organic material of unknown composition during their wet phase. In our previous study, we had largely ignored the potential effect of acclimation to the presence or absence of SE on growth rate (GÃCHTER & WEISSE 2006). Accordingly, a secondary goal of this study was to investigate whether addition of SE to the culture medium would enhance the temperature response, an d whether this effect may depend o n the physiological conditions o f the ciliates, including aging and long-term acclimation. We hypothesized that long-term acclimation to laboratory conditions (i.e., T, SE) does not affect growth rates, which is relevant to the interpretation of ecophysiologicallaboratory experiments and their extrapolation to the field.
The Role of Time-Varying Risk Premia in International Inter-Bank Markets

We study international interbank spreads within a no‐arbitrage dynamic term structure model and attempt to disentangle time‐varying risk premia in the interbank market for major currencies. Our results suggest that, at the peak of financial crisis, the interbank spread was clearly driven by liquidity risk. In the aftermath of the crisis, credit risk has become the dominant driver of the spread. This effect is stronger in the Euro and UK markets, due to the escalation of the European sovereign debt crisis, and weaker in the Japanese market which experienced remarkably low credit pressures. Furthermore, we assess the effectiveness of monetary policy actions and demonstrate that the establishment of the unconventional policy programmes led to the deterioration of liquidity risk in the interbank market, and the policy of major Central banks to substantially cut interest rates kept credit pressures at low levels. We also partition the spread into expectation hypothesis and time‐varying risk premium components and reject the hypothesis of constant risk premium. We find strong evidence of predictability inferred from the interbank spread model with time‐varying risk premia.

Detecção de begomovírus e ipomovírus em batata-doce nos estados de Pernambuco e Paraíba e fontes de resistência a Tomato chlorotic mottle virus e Potato virus Y em berinjela

O cultivo da batata-doce [Ipomoea batatas L. (Lam.)] e bastante amplo no Brasil, sendo praticado em grande parte do pais onde os maiores produtores sao: Rio Grande do Sul, Minas Gerais, Parana, Paraiba e Sao Paulo. Esta hortalica apresenta elevada importância, sobretudo para a populacao de baixa renda, especialmente pela rusticidade da planta, o facil cultivo e o baixo custo de producao, alem de ser uma boa fonte de energia e diversos nutrientes. Dentre os patogenos que acometem a cultura, os virus merecem destaque, principalmente algumas especies classificadas nos generos Potyvirus, Begomovirus e Ipomovirus. A batata-doce e hospedeira de uma ampla gama de especies virais que, muitas vezes, formam complexos e atuam em sinergismo, potencializando a doenca e causando consideravel reducao da produtividade. Um dos objetivos deste trabalho foi verificar a possivel presenca das especies do genero Begomovirus, e Sweet potato mild mottle virus (SPMMV), do genero Ipomovirus em 55 amostras de batata-doce, provenientes de Pernambuco e Paraiba, sendo 28 de campos comerciais e 27 de um Banco Ativo de Germoplasma (BAG). Para deteccao de begomovirus, o DNA das 55 amostras foi extraido, submetido a RCA e PCR usando os primers MA292 e MA293. Amplicons gerados de 17 amostras do BAG e tres amostras de campo foram selecionados, purificados e sequenciados. Apos analise confirmou-se a presenca de Sweet potato golden vein associated virus - SPGVaV em cinco amostras do BAG e duas de campo e Sweet potato leaf curl virus – SLCV em 12 amostras do BAG e uma de campo. O SPMMV foi detectado pelo teste Dot-ELISA atraves da utilizacao de anticorpo especifico em 24 das 27 amostras do BAG e 25 das 28 amostras de campo. Outra especie foco de estudo neste trabalho foi a berinjela (Solanum melongena L.), cultura alimentar economicamente importante disponivel em todo o mundo e com aproximadamente dois milhoes de hectares dedicados anualmente para o cultivo. No Brasil, em relacao a ocorrencia viral nesta solanacea, existem relatos apenas de especies do genero Tospovirus. Alem disto, em plantacoes de berinjela, praticamente, nao se observam sintomas virais, o que pode ser indicativo de ocorrencia de resistencia a virus. Dessa forma, outro objetivo deste trabalho foi avaliar o comportamento de genotipos de berinjela como possivel fonte de gene(s) de resistencia a virus que normalmente infectam especies da familia Solanaceae. Ensaios foram realizados utilizando-se as especies Tomato chlorotic mottle virus (ToCMoV), com inoculacao via vetor Bemisia tabaci, e Potato virus Y (PVY) por inoculacao mecânica. A avaliacao biologica para as duas especies virais foi feita mediante observacao de sintomas. As deteccoes de ToCMoV e PVY foram feitas usando-se sondas radioativas e teste Dot-ELISA, respectivamente. Os genotipos foram avaliados tambem quanto a resistencia ao vetor. Os materiais testados mostraram-se promissores para uso em programas de melhoramento tendo em vista a ausencia de sintomas e acumulacao viral
Research on Formation Keeping of Multi-rotor UAVs Based on Improved Virtual Structure Method

Multi-UAV cooperative formation flight (CFF) can greatly improve the damage resistance and mission completion efficiency of single UAV, so it has become a research hotspot in recent years. The entire process of multi-UAV formation flight can be decomposed into target tracking, formation keeping, obstacle avoidance and collision avoidance. The research of formation keeping mainly uses the leader-follower or virtual structure method. The former has the problem of single point of failure, and the formation error will be amplified step by step. The latter is difficult to select virtual leader, and is hard to adjust the formation adaptively with limited communication conditions. Based on the virtual structure and multicast method, this paper proposes a recursive fusion strategy which reduces the requirement of communication frequency between UAVs, increases the adaptability of formation to single point of failure, and improves the accuracy and adaptability of formation keeping to a certain extent. On this basis, the cascade PID model is used to design the formation controller. Finally, the effectiveness of the strategy is verified by using MATLAB.
Simultaneous inversion of two initial values for a time‐fractional diffusion‐wave equation

This study is devoted to recovering two initial values for a time‐fractional diffusion‐wave equation from boundary Cauchy data. We provide the uniqueness result for recovering two initial values simultaneously by the method of Laplace transformation and analytic continuation. And then we use a nonstationary iterative Tikhonov regularization method to solve the inverse problem and propose a finite dimensional approximation algorithm to find good approximations to the initial values. Numerical examples in one‐ and two‐dimensional cases are provided to show the effectiveness of the proposed method.
DIAGNÓSTICO DE ANAPLASMOSIS EQUINA VENEZOLANA MEDIANTE LA PRUEBA DE REACCIÓN EN CADENA DE LA POLIMERASA.

The disease caused by Anaplasma phagocytophilum is a zoonosis, that affects not only humans, but also horses (Equus caballus), donkeys (Equus africanus asinus), large and small ruminants (Bos taurus, Ovis aries, Capra aegagrus hircus), dogs (Canis lupus familiaris), cats (Felis catus), non-human primates (Macaca mulatta, Papio spp), birds (Turdus merula, Erithacus rubecula, Fringilla coelebs), wild hogs (Sus scrofa) and lamas (Lama glama). National laboratories, the diagnosis of A. phagocytophilum is performed by examining stained buffy coat smears with light microscopy to detect initial bodies and/or intracitoplasmic morulas within neutrophils and eosinophils. This test is simple to perform, but it has limited sensitivity and specificity. Equine anaplasmosis has not been adequately diagnosed and characterized in Venezuela, so little is known about its epidemiology, its prevalence, the diversity and pathogenicity of Venezuelan strains, their geographic distribution or the most common vectors. The objective of the study was to use polymerase chain reaction (PCR) to screen for the presence of A. phagocytophilum in Venezuelan equine populations. The species-specific PCR test used primers would amplify a 550 bp fragment of the gene encoding the P44 surface protein. Surprisingly, neither the PCR test nor the buffy coat smears detected the presence of A. phagocytophilum in any of the two hundred blood samples from horses with no apparent signs of disease sampled from different geographic regions of Venezuela. Possible reasons for the failure to detect A. phagocytophilum include, the sampling did not comprise endemic areas associated with subclinical forms of the disease; excess of gDNA from the host buffy coat may have interfered with the amplification of the target of interest; and epizootiological conditions that did not favour disease occurrence, including unsuitable habitat patches, absence of vectors and reservoirs, and/or lack of an adequate host-reservoir interaction in the explored areas.
Stage IV colorectal cancer presenting after necrotizing soft tissue infection

Abstract Necrotizing soft tissue infections (NSTIs) are highly aggressive and may be lethal if untreated. Polymicrobial infections of the groin and lower limb have been documented secondary to invasive colorectal cancer (CRC). We present a case of CRC diagnosed more than 4 years after the development of NSTI. There are documented cases of NSTIs concomitant with a preexisting CRC. In this case, however, the patient’s initial presentation was an NSTI followed by later diagnosis of CRC. A previously treated NSTI that is not healing appropriately may be an early indicator for CRC.
Möglichkeiten der Ernährungstherapie bei chronisch entzündlichen Darmerkrankungen

Nach derzeitigem Kenntnisstand haben Ernährungsgewohnheiten keinen signifikanten Einfluss auf die Pathogenese chronisch entzündlicher Darmerkrankungen (CED). Eine längere Stilldauer scheint Säuglinge jedoch vor späterer Erkrankung an CED zu schützen. Liegen im Zuge der Erkrankung Mangelzustände vor, ist eine spezielle Ernährungstherapie indiziert, vorzugsweise enteral – insbesondere bei Kindern.
Segmentation of local food consumers based on altruistic motives and perceived purchasing barriers: a Croatian study

Abstract This is the first empirical study which has segmented consumers based on their altruistic motives and perceived barriers in purchasing local food in a developing country, which has received little prior research attention and as such, provides a valuable contribution to the local food research stream. An empirical study was conducted via an online questionnaire on a sample of 402 Croatian local food consumers. In such a way we identified two consumer segments: (1) embedded local food consumers and (2) disinclined local food consumers. Embedded local food consumers report a significantly higher mean score concerning altruistic motives and a significantly lower mean score for perceived barriers in purchasing local food compared to the other segment. Also, they buy and consume local food more often and put more emphasis on personal motives, such as freshness, quality, and taste. Embedded local food consumers are more satisfied with the current local food supply and are willing to pay higher prices for local food as compared to disinclined local food consumers. This empirical study fills the evident research gap in local food literature regarding altruistic motives and barriers in purchasing locally produced food.
Data Extraction in Insurance Photo-Inspections Using Computer Vision

Recent advances in computer vision and artificial intelligence allow for a better processing of complex information in many fields of human activity. One such field is vehicle expertise and inspection. This paper presents the development of systems for the automatic reading of French and Spanish license plates, as well as odometer value reading in dashboard photographs. These were trained and validated with real examples of more than 4000 vehicles, while addressing typical problems with irregular data acquisition. The systems proposed have found use in a real environment and are employed as assistance in vehicle appraisal.
Coordination between discrete Mitotic Arrest Deficient 1 (MAD1) domains is required for efficient mitotic checkpoint signaling

As a sensitive signaling system, the mitotic checkpoint ensures faithful chromosome segregation by delaying anaphase onset when even a single kinetochore is unattached. The key signal amplification reaction for the checkpoint is the conformational conversion of open MAD2 (O-MAD2) into closed MAD2 (C-MAD2). The reaction was suggested to be catalyzed by an unusual catalyst, a MAD1:C-MAD2 tetramer, but how the catalysis is executed and regulated remains elusive. Here we report that in addition to the well-characterized middle region (MIM), both amino- and carboxyl-terminal domains (NTD and CTD) of MAD1 also contribute to the mitotic checkpoint. In contrast to MIM that stably associates with C-MAD2, MAD1-NTD and CTD surprisingly bind to both O-MAD2 and C-MAD2, suggesting their interactions with substrates and products of the O-C conversion. MAD1-NTD also interacts with CTD. MPS1 kinase interacts with and phosphorylates both NTD and CTD. The phosphorylation reduces the NTD:CTD interaction and CTD interaction with MPS1. Mutating CTD phosphorylation sites including Thr716 compromises MAD2 binding and the checkpoint responses. Ser610 and Tyr634 also contribute to the checkpoint. Our results have uncovered previously unknown interactions of MAD1-NTD and CTD with MAD2 conformers and their regulation by MPS1 kinase, providing novel insights into the mitotic checkpoint signaling.
Electrochemical Methods and (Bio) Sensors for Rosmarinic Acid Investigation

Rosmarinic acid (RA) is an important bioactive phenolic acid with significant biochemical activities, including the antioxidant one. It is widely found in plants of the families Lamiaceae and Boraginaceae and has many uses in the food, pharmaceutical and cosmetics industries. RA is an electroactive species owing to the presence of the two catechol groups in its structure. Due to their inherent characteristics, such as sensitivity, selectivity, ease of operation and not too high costs, electrochemical methods of analysis are interesting tools for the assessment of redox-active compounds. Moreover, there is a good correlation between the redox potential of the analyte and its capability to donate electrons and, consequently, its antioxidant activity. Therefore, this paper presents a detailed overview of the electrochemical (bio)sensors and methods, in both stationary and dynamic systems, applied for RA investigation under different aspects. These comprise its antioxidant activity, its interaction with biological important molecules and the quantification of RA or total polyphenolic content in different samples.
Optimal Scheduling Strategy of Building Integrated Photovoltaic Microgrid Considering Virtual Energy Storage

Building integrated photovoltaic (BIPV) is one of the most efficient ways to utilize renewable energy in buildings. However, the stochastic characteristic of PV power generation and load challenges the optimal dispatch of the BIPV. This paper proposes an optimal scheduling strategy of BIPV microgrid considering virtual energy storage (VES), which intends to further improve the operating economy of a BIPV microgrid. Firstly, existing research findings and gaps in this research area were analyzed. Then, the mathematical model of each unit in the system was created, meanwhile, the air conditioner-based VES (ACVES) model and electric water heater-based VES (EWHVES) model are built by exploiting the heat/cold storage capability of building and the electric water heater, respectively. Next, the optimal scheduling model considering the VES is designed. Finally, the optimal scheduling model is solved by CPLEX to obtain the optimal scheduling strategy that reduces the operating cost of the system. Simulation results demonstrate that the proposed strategy can reduce the operating cost of the system. Furthermore, the VES shows the potential to replace the battery energy storage system.
Tourism, transport, and land use: a dynamic impact assessment for Kaohsiung’s Asia New Bay Area

ABSTRACT This paper proposes a hybrid methodology for analysing the causal relations between public transportation development, tourism and land use by combining System Dynamics (SD) with Geographical Information Systems (GIS) and agent-based modelling (ABM). It is applied to illustrate the quantitative and spatial effect of the two phases Light Rail Transit (LRT) development in Asia New Bay Area, Kaohsiung, Taiwan. This paper also furthers the application of the ABM spatial information as interactive variables in the stocks-flow model. The simulation results support that development policies of LRT are significant to the future tourism in Asia New Bay Area, while the under debate second phase of LRT is estimated to raise the number of visitors in long term by alleviating the deteriorating road traffic congestion. This policy-oriented simulation can serve as a reference to the decision-makers towards the future management of LRT.
Processo para Reconhecimento e Tradução de Sinais em LIBRAS Utilizando Redes Neurais Artificiais

Recognized by law, the Brazilian Sign Language (LIBRAS), is thesecond Brazilian official language and, according to IBGE (BrazilianInstitute of Geography and Statistics), Brazil has a large communityof hearing-impaired people, with approximately nine million ofdeaf people. Besides that, most of the non-deaf community cannotcommunicate or understand this language. Considering that, theuse of LIBRAS’ interpreters becomes extremely necessary in orderto allow a greater inclusion of people with this type of disabilitywith the whole community. However, an alternative solution tothis problem would be to use artificial neural network methods forthe LIBRAS recognition and translation. In this work, a processof LIBRAS’ recognition and translation is presented, using videosas input and a convolutional-recurrent neural network, known asConvLSTM. This type of neural network receives the sequence offrames from the videos and analyzes, frame by frame, if the framebelongs to the video and if the video belongs to a specific class.This analysis is done in two steps: first, the image is analyzed inthe convolutional layer of the network and, after that, it is sent tothe network recurrent layer. In the current version of the implementednetwork, data collection has already been carried out, theconvolutional-recurrent neural network has been trained and it ispossible to recognize when a given LIBRAS’ video represents ornot a specific sentence in this language.
Turmeric and sorghum for egg-laying quails

Abstract The aim of the present study was to assess the effect of adding different turmeric amounts to sorghum-based diets for Japanese quails on animal performance, animal metabolism, yolk colour, egg quality, blood and liver biochemical parameters and sensory attributes of the eggs. The study included 210 egg-laying quails aged 50 days and lasted for 90 days. The study had a completely randomised design with six treatments and five replicates with seven birds per replicate. A control corn-based feed and sorghum-based feeds to which different turmeric levels were added (0%, 0.5%, 1.0%, 1.5% and 2%) were tested. The results showed that the sorghum-based feeds with added turmeric levels did not affect animal performance, metabolisation of protein and ether extract, internal and external quality of eggs, serum biochemical profile, including calcium, phosphorous, protein and liver transaminase enzymes. Blood cholesterol and triglyceride levels decreased when ≥0.5% percentages of turmeric were added to the feed. Yolk colour of the treatments differed significantly from that of the control, but the yolks were considered well suited for consumption. Turmeric reduced the cholesterol and triglyceride levels in egg-laying quails.
