Ironic Faith in Monty Python’s Life of Brian

Monty Python’s Life of Brian tells the story of Brian, a contemporary of Jesus whose life becomes chaotic when he is mistaken for a messiah. Standard comedic devices are used to mock and ridicule those who use their authority or office to claim that they are more than human. In this case, laughter humbles those individuals and brings them back to the human community. Second, an ironic faith perspective allows the Pythons to assert that it is up to each individual to define the meaning of his/her own life. While some interpretations of ironic faith suggest the possibility of an ethical response to the perception of the gap between what is and what ought to be, the vision of the absurd in Life of Brian is focused more on the individual than on the community. The end result of an ironic faith is not a call to change the world but inclusion in a community of people who share the same ironic vision

Trap-Assisted Tunneling in the Schottky Barrier

The paper presents a new way how to calculate the currents in a Schottky barrier. The novel phenomeno-logical model extends the Shockley-Read-Hall recombi-nation-generation theory of trap-assisted tunneling. The proposed approach explains the occurrence of large leakage currents in Schottky structures on wide band semi-conductors with a high Schottky barrier (above 1 eV) and with a high density of traps. Under certain conditions, trap-assisted tunneling (TAT) plays a more important role than direct tunneling

beta-Cu2V2O7: a spin-1/2 honeycomb lattice system

We report on band structure calculations and a microscopic model of the low-dimensional magnet beta-Cu2V2O7. Magnetic properties of this compound can be described by a spin-1/2 anisotropic honeycomb lattice model with the averaged coupling \bar J1=60-66 K. The low symmetry of the crystal structure leads to two inequivalent couplings J1 and J1', but this weak spatial anisotropy does not affect the essential physics of the honeycomb spin lattice. The structural realization of the honeycomb lattice is highly non-trivial: the leading interactions J1 and J1' run via double bridges of VO4 tetrahedra between spatially separated Cu atoms, while the interactions between structural nearest neighbors are negligible. The non-negligible inter-plane coupling Jperp~15 K gives rise to the long-range magnetic ordering at TN~26 K. Our model simulations improve the fit of the magnetic susceptibility data, compared to the previously assumed spin-chain models. Additionally, the simulated ordering temperature of 27 K is in remarkable agreement with the experiment. Our study evaluates beta-Cu2V2O7 as the best available experimental realization of the spin-1/2 Heisenberg model on the honeycomb lattice. We also provide an instructive comparison of different band structure codes and computational approaches to the evaluation of exchange couplings in magnetic insulators.Comment: 11 pages, 10 figures, 2 tables: revised version, extended description of simulation result

Plant immunity and beyond: Signals from proteins & peptides

Plants are the primary and most important source of food for human consumption, besides their ecological importance, since they define the diverse ecosystems worldwide. Because of their position in the ecological chain as primary supplier of biomass and food for other organisms, plants are also fundamental for animals, fungi and microorganisms, and some of them are also beneficial to other plants. Humans rely mostly on plant products for food, and many plants provide important non-food products, including wood, textiles, medicines, cosmetics, soaps, rubber, plastics, paints and other industrial chemicals. Moreover, plants are also fundamental for animal feeding, including not only mammals (e.g. cattle, sheep and goats), but also poultry and aquaculture (e.g., fish and shrimp farming)

GENOSOJA - The Brazilian Soybean Genome Consortium: high throughput omics and beyond.

Plant genomes are among the most complex and large ones of our planet, with high levels of redundancy when compared to other eukaryotic groups, leading to intricate processes for gene regulation and evolution. Such a complexity demands interdisciplinary and multidimensional approaches in order to allow a better understanding of the processes able to exploit the whole potential of the existing genes in different species, including crop plants. Among cultivated plants, soybean [Glycine max (L.) Merr.] occupies an outstanding position due to its importance as source of protein and oil that may also be converted into biodiesel. The seeds are rarely consumed in natura, but many traditional food products have been consumed, as soymilk, and tofu, as well as fermented products as soy sauce, and soy paste among others, besides its wide use for animal feed. Soybean cultivation has been highly concentrated geographically, with only four countries (USA, Brazil, Argentina and China) accounting for almost 90% of world output. Asia (excluding China) and Africa, the two regions where most of the food insecure countries are located, account for only 5% of production. Among countries classified as 'undernourished', only India and Bolivia are significant producers of soybeans (FAO, 2009). Available evidences indicate that the cultivated soybean was domesticated from its wild relative Glycine soja (Sieb. and Zucc.) in China about 5,000 years ago (Carter et al., 2004). Since then, soybean has been grown primarily in temperate regions for thousands of years, first in Northern Asia and in more recent years in North America and countries of the Southern Cone of Latin America (FAO, 2009). The remarkable success of this crop in temperate zones is well known, but the crop presents also an important role in cropping systems of the tropics and subtropics, also in low fertile regions, as the Brazilian cerrado savannah (Spehar, 1995). The actual area cultivated worldwide with soybean is estimated to cover 103.5 millions of hectares, from which 24.2 only in Brazil, with considerable increases in the production achieved without significant increase in the cultivated area (Embrapa Soybean, 2011). As a legume, soybean is able to develop symbiotic interactions with rhizobia, allowing the fixation and assimilation of atmospheric N2, bearing quite specific mechanisms to coordinate this complex interaction (Oldroyd and Downie, 2008), absent in most angiosperm groups. Besides this peculiarity, soybean presents 2n = 40 chromosomes and was early characterized as an ancient polyploid (paleopolyploid) through genetic mapping studies that identified homeologous chromosome regions based upon duplicate RFLP markers (Shoemaker et al., 1996; Lee et al., 1999; 2001). Due to its allopolyploid nature, the first approaches regarded the generation of expressed sequences from different library tissues and conditions, including mainly ESTs (Expressed Sequence Tags; Nelson et al., 2005) partially in annotated databases, including ca. 40.000 full length cDNA clones available (Umezawa et al., 2008, see also RIKEN Soybean Full-Length cDNA Database), besides analyses regarding RNAseq under different tissues and development stages, as well as under different stressing situations (e.g. Libault et al., 2010; Severin et al., 2010). Also a complete shotgun genome sequence of the soybean cultivar Williams 82 was released, comprising 1.1-gigabase genome size allowing the integration of physical and high-density genetic maps, including 46,430 predicted protein-coding genes (Schmutz et al., 2010). The total amount of data publicly available at GenBank (NCBI) includes more than 120,000 nucleotide sequences (mainly mRNA), ~1,460,000 ESTs, ~368,000 genome sequences, ~80,000 proteins, 118 deposited structures and more than 6,2 million SNPs. Such numbers show that working with soybean is a very challenging task. By the other hand, despite of the wide data availability, most data regard cultivars from temperate regions (as Williams 82), not adapted for cultivation under tropical conditions, as it is the case of central Brazil and many other tropical countries that are subjected to distinct environmental stresses. The proposition of creating the GENOSOJA consortium was submitted in 2007 to the National Council for Scientific and Technological Development (CNPq), an agency linked to the Brazilian Ministry of Science and Technology (MCT), starting its activity in March 2008 with the participation of nine Brazilian institutions from different regions (Figure 1). The proposal aimed to study the soybean genome from its organization into the structural level, seeking to characterize and sequence important genomic regions and their products, thus contributing to the identification of genes using transcriptional and proteomic methods, especially considering the plant response to different biotic and abiotic stresses that affect the culture in the Southern hemisphere. Still, the GENOSOJA network aimed to approach not only whether a gene is induced or suppressed under a given condition, but also to determine the levels at which it is expressed, the interactions with other genes, their physical location and products, allowing the identification of important genes and metabolic pathways, vital for the development and study of plants tolerant to challenging situations. The GENOSOJA project is still in course and is structured into six Project Components (Figure 2), including management and addressing of different aspects of the soybean genome: I. Project management - responsible for the project administration, organization of meetings, group integration and research reports, among others. II. Structural Genomics - includes research activities related to the genomic physical architecture, including BAC anchoring (in the cultivar Conquista), promoter analysis and sequencing of gene-rich regions, also in comparison with other wild relatives of the genus Glycine, allowing studies of synteny and indication of regions important for ressequencing. This component is also responsible for the identification of single base polymorphisms (SNPs), very important for mapping purposes and marker assisted selection. III. Transcriptomics -comprises the largest research group, responsible for various expression profiling approaches using different strategies to access transcripts generated under different biotic (Asian rust: Phakopsora pachyrhizi, CPMMV: Cowpea mild mottle virus, nematodes: Meloydogyne javanica and Pratylenchus brachyurus) and abiotic (water deficit) stresses. In this workgroup different strategies were used, including: a) Subtractive cDNA libraries (76 bp tags, Solexa Illumina® sequencing) using contrasting materials submitted to biotic interactions, including diseases (~40 million tags; Asian rust and virus inoculation) and beneficial interactions (~10 million tags; inoculation with Bradyrhizobium japonicum), as well as water deficit (~42 million tags, comparing tolerant and susceptible accessions). b) SuperSAGE comprising ~3,2 Solexa Illumina® 26-bp tags distributed in six libraries generated under biotic (water deficit) and abiotic (Asian rust) stress comparisons. c) MicroRNA libraries (Solexa Illumina®, 1924 bp) including four libraries regarding water deficit ( 4,8 millions miRNAs) and other four regarding Asian rust (~7,9 million miRNAs). d) cDNA sequences (2,112 sequences, Sanger method) from roots infested with the nematode M. javanica compared with non stressed control. The three first above mentioned experiments were carried out using the same experimental conditions, generating an extensive comparable dataset to allow the understanding of the gene expression dynamic (Subtractive cDNA and SuperSAGE libraries), including biotic and abiotic cross-talk responses as well as the post transcriptional control (miRNA). IV. Proteomics -aimed to study the protein profile of soybean plants, low-mass protein and peptides identification and protein-protein interactions, using the same accessions and biological conditions established for the transcriptomic analyses to ensure complementarity and reduction of experimental variability, and thus, allowing the integration of both datasets in the functional characterization of the soybean genome. V. Expression Assays (transgenesis) -considering the results of transcriptomics and proteomics, most valuable gene candidates are being transformed in order to infer about their effects or biological function. Members of this group are also evaluating the vicinity of genes (UTRs) for the identification of regulatory regions (promoters, enhancers, cis-elements, etc.) that control their expression. VI. Bioinformatics -this workgroup developed the GENOSOJA database (see web resource) that includes a set of tools integrating the entire project data as compared with available sequences from other public data banks. The present issue represents the starting point of an extensive catalogue of products generated by the GENO-SOJA consortium, since all members agree that many additional inferences will be soon mature for publication and application to breeding projects. Thousands of candidate genes differentially expressed have been identified and are being validated using quantitative real time PCR, many regarding strongly induced genes in contrasting libraries (e.g. stressed against control or tolerant against sensible in the same condition). Many of them refer to uncharacterized genes, with no given function, representing relevant data to be worked out in future functional studies, since they may represent not yet described genes, some possibly unique to legumes and important for plant breeding. Finally, the present volume does not represent a milestone for completion of the GENOSOJA project, but an announcement of its birth, crowned with solid growth, integration and consolidation prospects. The data generated by the GENOSOJA consortium will also join the worldwide effort to study the soybean genome through the participation in the International Soybean Genome Consortium (ISGC). In this sense, the next step involves the public release of the generated data, which shall be available for the world community, allowing the effective integration with other networks throughout the world

Xtru3D: Single-View 3D Object Reconstruction from Color and Depth Data

D object reconstruction from single image has been a noticeable research trend in recent years. The most common method is to rely on symmetries of real-life objects, but these are hard to compute in practice. However, a large class of everyday objects, especially when manufactured, can be generated by extruding a 2D shape through an extrusion axis. This paper proposes to exploit this property to acquire 3D object models using a single RGB+Depth image, such as those provided by available low-cost range cameras. It estimates the hidden parts by exploiting the geometrical properties of everyday objects, and both depth and color information are combined to refine the model of the object of interest. Experimental results on a set of 12 common objects are shown to demonstrate not only the effectiveness and simplicity of our approach, but also its applicability for tasks such as robotic grasping.The research leading to these results has been funded by the HANDLE European project (FP7/2007-2013) under grant agreement ICT 231640-http://www.handle-project.eu.Publicad

Preparation of delafossite CuFeO2 thin films by rf-sputtering on conventional glass substrate

CuFeO2 CuFeO2 is a delafossite-type compound and is a well known p-type semiconductor. The growth of delafossite CuFeO2 thin films on conventional glass substrate by radio-frequency sputtering is reported. The deposition, performed at room temperature leads to an amorphous phase with extremely low roughness and high density. The films consisted of a well crystallized delafossite CuFeO2 after heat treatment at 450 °C in inert atmosphere. The electrical conductivity of the film was 1 mS/cm. The direct optical band gap was estimated to be 2 eV

Acute and long-term effects of a single dose of MDMA on aggression in Dark Agouti rats

MDMA causes selective depletion of serotonergic terminals in experimental animals and the consequent decrease in synaptic 5-HT may, inter alia, increase impulsivity. To study the effects of MDMA upon brain function, the behaviour of male Dark Agouti rats exposed to MDMA (15 mg/kg i.p.), two 5-HT1B agonists (CGS-12066A and CP-94,253, both 5 mg/kg i.p.) or saline were investigated in the resident-intruder test. Studies were performed in drug-naive rats and also in rats exposed to MDMA (15 mg/kg i.p.) 21 d earlier. In parallel experiments the functional neuroanatomy of MDMA effects were assessed using 2-deoxyglucose imaging of local cerebral metabolic rate of glucose utilization (LCMRGlu) and neurotoxicity was assessed by measuring [H-3]paroxetine binding. There was no significant difference in aggressive behaviour (biting, boxing, wrestling and their latencies) between drug-naive rats and rats previously exposed to MDMA 21 d earlier, despite reduced social behaviour, decreased LCMRGlu in several brain areas involved in aggression, and reductions in paroxetine binding by 30-60'% in the forebrain. CGS12066A, CP-94,253 and acute MDMA produced marked decreases in aggressive behaviours, especially in biting, boxing and kicking found in drug-naive rats. In animals previously exposed to the drug, acute antiaggressive effects of MDMA were, in general, preserved as were MDMA-induced increases in LCMRGlu. Our studies provide evidence that in the resident-intruder test, where social isolation is a requirement, aggressive behaviour and acute anti-aggressive effects of MDMA and 5-HT,I, receptor agonists remain intact 3 wk after a single dose of the drug despite significant damage to the serotonergic system
