    O trabalho pretende colocar em pauta uma discussão sobre o requisito da justa indenização nas ações de desapropriação por utilidade pública, no caso da população de interesse social (de 0 a 3 salários mínimos), considerando o regime jurídico que ampara o direito fundamental à moradia e o direito à cidade. Problematizando esse tema, busca-se inicialmente expor o regime jurídico que fundamenta o direito à moradia e odireito à cidade; procedendo-se em seguida uma abordagem sobre o instituto da desapropriação –em face tanto do domínio quanto da posse – em seus elementos centrais (onde se coloca o requisito da justa indenização), enfocando-se o tratamento da doutrina e da jurisprudência sobre a questão e colocando em pauta o novo tratamento ao direito fundamental à moradia posto na Constituição Federal de 1988 e o marco regulatório do direito à cidade, com foco na população de interesse social. Tratando da inaplicabilidade do Dec.-lei 3.365/1941 em face da Carta Magna de 1988 e o Estatuto da Cidade (Lei 10.257/2001), a discussão traz o foco para o contexto dos megaeventos esportivos (Copado Mundo – 2014 e Olimpíadas – 2016), onde o Estado– ente que tem o dever objetivo de concretizar/ efetivar o direito fundamental à moradia – não visualiza a situação de vulnerabilidade de uma população de interesse social, para a qual, em razão de sua exclusão do acesso ao mercado imobiliário formal, o conceito de justa indenização deve ser visto de forma ampliada, relacionando-se, de maneira intrínseca, com o direito à moradia (art. 6.º, caput, da CF/1988, com o direito à cidade posto legalmente no Estatuto da Cidade (Lei 10.257/2001) e com o princípio da dignidade da pessoa humana (art.1.º, III, da CF/1988).

    POCI-01-0247-FEDER-038436Industry 4.0, allied with the growth and democratization of Artificial Intelligence (AI) and the advent of IoT, is paving the way for the complete digitization and automation of industrial processes. Maintenance is one of these processes, where the introduction of a predictive approach, as opposed to the traditional techniques, is expected to considerably improve the industry maintenance strategies with gains such as reduced downtime, improved equipment effectiveness, lower maintenance costs, increased return on assets, risk mitigation, and, ultimately, profitable growth. With predictive maintenance, dedicated sensors monitor the critical points of assets. The sensor data then feed into machine learning algorithms that can infer the asset health status and inform operators and decision-makers. With this in mind, in this paper, we present TIP4.0, a platform for predictive maintenance based on a modular software solution for edge computing gateways. TIP4.0 is built around Yocto, which makes it readily available and compliant with Commercial Off-the-Shelf (COTS) or proprietary hardware. TIP4.0 was conceived with an industry mindset with communication interfaces that allow it to serve sensor networks in the shop floor and modular software architecture that allows it to be easily adjusted to new deployment scenarios. To showcase its potential, the TIP4.0 platform was validated over COTS hardware, and we considered a public data-set for the simulation of predictive maintenance scenarios. We used a Convolution Neural Network (CNN) architecture, which provided competitive performance over the state-of-the-art approaches, while being approximately four-times and two-times faster than the uncompressed model inference on the Central Processing Unit (CPU) and Graphical Processing Unit, respectively. These results highlight the capabilities of distributed large-scale edge computing over industrial scenarios.publishersversionpublishe

    Our goal was to create bio-functional chlorhexidine (CHX)-doped thin films on commercially pure titanium (cpTi) discs using the glow discharge plasma approach. Different plasma deposition times (50, 35 and 20 min) were used to create bio-functional surfaces based on silicon films with CHX that were compared to the control groups [no CHX and bulk cpTi surface (machined)]. Physico-chemical and biological characterizations included: 1. Morphology, roughness, elemental chemical composition, film thickness, contact angle and surface free energy; 2. CHX-release rate; 3. Antibacterial effect on Streptococcus sanguinis biofilms at 24, 48 and 72 h; 4. Cytotoxicity and metabolic activity using fibroblasts cell culture (NIH-F3T3 cells) at 1, 2, 3 and 4 days; 5. Protein expression by NIH-F3T3 cells at 1, 2, 3 and 4 days; and 6. Co-culture assay of fibroblasts cells and S. sanguinis to assess live and dead cells on the confocal laser scanning microscopy, mitochondrial activity (XTT), membrane leakage (LDH release), and metabolic activity (WST-1 assay) at 1, 2 and 3 days of co-incubation. Data analysis showed that silicon films, with or without CHX coated cpTi discs, increased surface wettability and free energy (p 0.05), whereas cell metabolism (MTT assay) was affected by CHX, with the 35 min of plasma deposition time group displaying the lowest values as compared to bulk cpTi (p 0.05). Altogether, the findings of the current study support the conclusion that silicon films added with CHX can be successfully created on titanium discs and have the potential to affect bacterial growth and inflammatory markers without affecting cell viability/proliferation rates

    IL-10 overexpression predisposes to invasive aspergillosis by suppressing antifungal immunity

    © 2017 American Academy of Allergy, Asthma & ImmunologyProinflammatory immune responses are critically required for antimicrobial host defenses; however, excessive inflammation has the potential to damage host tissues thereby paradoxically contributing to the progression of infection. A central negative regulator of inflammatory responses is IL-10, an immunosuppressive cytokine with a wide variety of functions across multiple cell types. Although the role of IL-10 during infection appears to vary for different microorganisms, a largely detrimental role has been attributed to this cytokine during fungal disease. Given the variable risk of infection and its outcome among patients with comparable predisposing factors, susceptibility to invasive aspergillosis (IA) is thought to rely largely on genetic predisposition. The initial investigation of genetic variability at the IL10 locus led to the identification of single nucleotide polymorphisms (SNPs) influencing its transcriptional activity; thus, IL-10 may be a reasonable candidate for the genetic regulation of susceptibility to IA in high-risk patients.Supported by the Northern Portugal Regional Operational Programme (NORTE 2020), under the Portugal 2020 Partnership Agreement, through the European Regional Development Fund (FEDER) (NORTE-01-0145-FEDER-000013), the Fundação para a Ciência e Tecnologia (FCT) (contracts IF/00735/2014 to A.C., IF/01390/2014 to E.T., IF/00021/2014 to R.S., and SFRH/BPD/96176/2013 to C.C.), the Conselho de Reitores das Universidades Portuguesas (CRUP), Portugal (Ações Integradas Luso-Alemãs A-43/16), the Deutscher Akademischer Austauschdienst (DAAD) (project-ID 57212690), the Fondo de Investigaciones Sanitarias (Madrid, Spain) (grant #PI12/02688) and the ERA-NET PathoGenoMics (grant #0315900A).info:eu-repo/semantics/publishedVersio

    Evolutionary determinism and convergence associated with water-column transitions in marine fishes

    Get PDF
    Repeatable, convergent outcomes are prima facie evidence for determinism in evolutionary processes. Among fishes, well-known examples include microevolutionary habitat transitions into the water column, where freshwater populations (e.g., sticklebacks, cichlids, and whitefishes) recurrently diverge toward slender-bodied pelagic forms and deep-bodied benthic forms. However, the consequences of such processes at deeper macroevolutionary scales in the marine environment are less clear. We applied a phylogenomics-based integrative, comparative approach to test hypotheses about the scope and strength of convergence in a marine fish clade with a worldwide distribution (snappers and fusiliers, family Lutjanidae) featuring multiple water-column transitions over the past 45 million years. We collected genome-wide exon data for 110 (∼80%) species in the group and aggregated data layers for body shape, habitat occupancy, geographic distribution, and paleontological and geological information. We also implemented approaches using genomic subsets to account for phylogenetic uncertainty in comparative analyses. Our results show independent incursions into the water column by ancestral benthic lineages in all major oceanic basins. These evolutionary transitions are persistently associated with convergent phenotypes, where deep-bodied benthic forms with truncate caudal fins repeatedly evolve into slender midwater species with furcate caudal fins. Lineage diversification and transition dynamics vary asymmetrically between habitats, with benthic lineages diversifying faster and colonizing midwater habitats more often than the reverse. Convergent ecological and functional phenotypes along the benthic–pelagic axis are pervasive among different lineages and across vastly different evolutionary scales, achieving predictable high-fitness solutions for similar environmental challenges, ultimately demonstrating strong determinism in fish body-shape evolution. This is a postprint of the published article.This research was supported by NSF grants DEB-1932759 and DEB-1929248 to R.B.-R., DEB-1457426 and DEB-1541554 to G.O., DEB-1541552 to C.C.B., and DEB-2015404 to D.A.
