«Precisione di un’ideologia». Edoardo Persico tra Venti e Trenta: arte, critica, architettura
Creators: name: Dantini, Michele

description: Per chi studia l’arte italiana del Novecento e desidera verificare se e quali continuità possano esservi state tra prima e seconda metà del secolo, la figura di Persico, ad oggi scarsamente decifrata, è un passaggio obbligato. È vero: talvolta risuona il luogo comune secondo cui le tracce dell’attività di Persico, in ambito figurativo, sarebbero state «brevi» e «lievi». Ma è appunto questo luogo comune che si intende qui sfidare, segnalando istanze, prospettive o «ideologie» che Persico sviluppa già nel decennio di formazione e che sono poi destinate a orientare in modo molteplice, sul «lungo periodo», l’attività di questo o quell’artista a lui legato da vincoli intellettuali e affettivi (da Garbari a Fontana a Birolli, per esemplificare; senza dimenticare Rosai). Occorre riferirsi in primo luogo al tema dell’«arte sacra», che Persico invita, sulle tracce di Maritain, suo filosofo-teologo guida, a rinnovare in profondità, disertando iconografie, tecniche e generi tradizionali; e all’incoraggiamento del dialogo tra arte e architettura, che Persico stesso, a partire dal 1934, persegue su piani anche pratici contribuendo in misura decisiva alla progettazione di «ambienti». Occorre riferirsi soprattutto a una circostanza almeno in parte meta- o extra-stilistica, tuttavia dirimente, che regola in Persico i rapporti tra arte italiana e arte europea, tra «tradizione» e modernità. In sintesi: alla luce di principi e convinzioni radicate, a cavallo tra anni Venti e Trenta Persico matura un modello di modernità (o meglio di modernismo) italiano altamente differenziato e specifico, per così dire sincretico, attraverso cui si prefigge di tenere assieme aperture cosmopolite e memoria della madrelingua tre-quattrocentesca; «europeismo» e «nazione». Tale modello, implicitamente non collaborazionista e anticoncordatario sotto profili politici, appare già abbozzato nei primi testi «torinesi» dedicati alle arti figurative e trova esplicita formulazione nel 1930, con l’appello alla «rivolta cattolica». Ha un duplice senso polemico: è rivolto sia contro Strapaese che contro Stracittà o le frange più ufficiali del Novecento.

description: BACKGROUND: Genomic islands can be observed in many microbial genomes. These stretches of DNA have a conspicuous composition with regard to sequence or encoded functions. Genomic islands are assumed to be frequently acquired via horizontal gene transfer. For the analysis of genome structure and the study of horizontal gene transfer, it is necessary to reliably identify and characterize these islands. RESULTS: A scoring scheme on codon frequencies Score_G1G2(cdn) = log(f_G2(cdn) / f_G1(cdn)) was utilized. To analyse genes of a species G1 and to test their relatedness to species G2, scores were determined by applying the formula to log-odds derived from mean codon frequencies of the two genomes. A non-redundant set of nearly 400 codon usage tables comprising microbial species was derived; its members were used alternatively at position G2. Genes having at least one score value above a species-specific and dynamically determined cut-off value were analysed further. By means of cluster analysis, genes were identified that comprise clusters of statistically significant size. These clusters were predicted as genomic islands. Finally and individually for each of these genes, the taxonomical relation among those species responsible for significant scores was interpreted. The validity of the approach and its limitations were made plausible by an extensive analysis of natural genes and synthetic ones aimed at modelling the process of gene amelioration. CONCLUSIONS: The method reliably allows to identify genomic island and the likely origin of alien genes.

description: Der Moskauer Vertrag von 1970 gilt als einer der wichtigsten Verträge der Nachkriegsgeschichte. Durch ihn verständigten sich die Bundesrepublik Deutschland und die Sowjetunion darauf, zukünftige Konflikte friedlich zu lösen und die europäischen Grenzen als unverletzlich anzuerkennen. Auf diese Weise markierte das Abkommen die Grundlage für die weiteren Ostverträge. Kürzlich veröffentlichte Archivalien ermöglichen nun einen neuartigen Blick auf die Genese des Moskauer Vertrags und die damit zusammenhängende neue sowjetische Westpolitik, die in der bisherigen Forschung oft vernachlässigt wurde.

description: In the present work we study, both theoretically and experimentally, the temperature increase in a bulk high-temperature superconductor subjected to applied AC magnetic fields of large amplitude. We calculate analytically the equilibrium temperatures of the bulk sample as a function of the experimental parameters using a simple critical-state model for an infinitely long type-II superconducting slab or cylinder. The results show the existence of a limit heat transfer coefficient (AUlim) separating two thermal regimes with different characteristics. The theoretical analysis predicts a "forbidden" temperature window within which the temperature of the superconductor can never stabilize when the heat transfer coefficient is small. In addition, we determine an analytical expression of two threshold fields Htr1 and Htr2 characterizing the importance of magneto-thermal effects and show that a thermal runaway always occurs when the field amplitude is larger than Htr2. The theoretical predictions of the temperature evolution of the bulk sample during a self-heating process agree well with the experimental data. The simple analytical study presented in this paper enables order of magnitude thermal effects to be estimated for simple superconductor geometries under applied AC magnetic fields and can be used to predict the influence of experimental parameters on the self-heating characteristics of bulk type-II superconductors.

description: Mechanistic investigation of three homogeneous, photochemical proton reduction systems that comprise Ir or Cu based photosensitizers and iron carbonyl catalysts to produce hydrogen. Operando IR spectroscopy coupled with gas volumetry was applied supported by other spectroscopic techniques. The rate determining steps, deactivation mechanisms and catalytic key species were determined, with the latter being a self-assembling [FeFe]-hydrogenase mimic in case phosphines are present as co-catalysts in the reaction mixture. These results lead to a better understanding and improvement of the systems.

description: In this paper we study Yangians of sl(n|m) superalgebras. We derive the universal R-matrix and evaluate it on the fundamental representation obtaining the standard Yang R-matrix with unitary dressing factors. For m=0, we directly recover up to a CDD factor the well-known S-matrices for relativistic integrable models with su(N) symmetry. Hence, the universal R-matrix found provides an abstract plug-in formula, which leads to results obeying fundamental physical constraints: crossing symmetry, unitrarity and the Yang-Baxter equation. This implies that the Yangian double unifies all desired symmetries into one algebraic structure. In particular, our analysis is valid in the case of sl(n|n), where one has to extend the algebra by an additional generator leading to the algebra gl(n|n). We find two-parameter families of scalar factors in this case and provide a detailed study for gl(1|1).

description: Der Langzeitverlauf nach schwerer akuter Pankreatitis nach primär konservativer Therapie ist bisher nur eingeschränkt untersucht, und es liegen nur wenige Daten zu dieser Thematik vor. Auf Grund dessen sind bereits kleine Fallzahlen, wie in der hier vorliegenden Studie, von Bedeutung. Die dargestellten Ergebnisse zeigen, dass die primär konservative Therapie sicher ist und sich keine Nachteile im Langzeitverlauf ergeben. Zudem kann die Langzeitmortalität durch die primär konservative Therapie gegenüber dem operativen Nekrosektomieverfahren signifikant gesenkt werden.

description: BACKGROUND: Microorganisms and plants are able to produce tryptophan. Enzymes catalysing the last seven steps of tryptophan biosynthesis are encoded in the canonical trp operon. Among the trp genes are most frequently trpA and trpB, which code for the alpha and beta subunit of tryptophan synthase. In several prokaryotic genomes, two variants of trpB (named trpB1 or trpB2) occur in different combinations. The evolutionary history of these trpB genes is under debate. RESULTS: In order to study the evolution of trp genes, completely sequenced archeal and bacterial genomes containing trpB were analysed. Phylogenetic trees indicated that TrpB sequences constitute four distinct groups; their composition is in agreement with the location of respective genes. The first group consisted exclusively of trpB1 genes most of which belonged to trp operons. Groups two to four contained trpB2 genes. The largest group (trpB2_o) contained trpB2 genes all located outside of operons. Most of these genes originated from species possessing an operon-based trpB1 in addition. Groups three and four pertain to trpB2 genes of those genomes containing exclusively one or two trpB2 genes, but no trpB1. One group (trpB2_i) consisted of trpB2 genes located inside, the other (trpB2_a) of trpB2 genes located outside the trp operon. TrpA and TrpB form a heterodimer and cooperate biochemically. In order to characterise trpB variants and stages of TrpA/TrpB cooperation in silico, several approaches were combined. Phylogenetic trees were constructed for all trp genes; their structure was assessed via bootstrapping. Alternative models of trpB evolution were evaluated with parsimony arguments. The four groups of trpB variants were correlated with archeal speciation. Several stages of TrpA/TrpB cooperation were identified and trpB variants were characterised. Most plausibly, trpB2 represents the predecessor of the modern trpB gene, and trpB1 evolved in an ancestral bacterium. CONCLUSION: In archeal genomes, several stages of trpB evolution, TrpA/TrpB cooperation, and operon formation can be observed. Thus, archeal trp genes may serve as a model system for studying the evolution of protein-protein interactions and operon formation.
Linking soil biotic and abiotic factors to sweet cherry tree establishment in new and old Okanagan Valley orchards
Creators: name: Munro, Paige
Publisher: name: University of British Columbia
Year: 2018

description: In the Okanagan Valley of British Columbia, sweet cherry (Prunus avium L.) has traditionally been replanted into soil that previously supported tree fruits. However, growth of young fruit trees replanted into old orchard soil is often poor and thought to be due to plant-parasitic nematodes (i.e. Pratylenchus spp.) and fungi. Due to climate change, cherry production is expanding into northern and higher elevation areas of this region that were not previously cultivated to tree fruits. Models have considered how climate and soil physicochemical properties will influence cherry range expansion, but they have not considered soil biology. The first objective of this study was to compare soil from 18 old (n=12) and new orchard soils (n=6) with respect to the influence of soil biology on cherry growth, by measuring plant growth response to sterilization in a bioassay, and to determine which biotic and abiotic properties best predict cherry growth among this array of orchard soils. Shoot height increment was significantly greater in untreated (non-sterilized) new soil relative to old soil where microbial activity was reduced (sterilized). According to multiple regression, the variables FDA hydrolysis, organic carbon, and sodium were positive predictors of plant growth for both new and old soils. Using greenhouse and field experiments, the second objective of this study investigated how compost and woodchip mulch application affected soil biotic and abiotic properties compared to non-amended soil in two new, northern, and two old, central Okanagan sweet cherry orchards over two growing seasons. In the field study, compost-amended soil resulted in greater soil nutrient status at all four orchards, but there were few effects on soil biological properties. In the greenhouse study, amended soil from both new sites and one old site resulted in lower Pratylenchus root colonization than non-amended soil. Overall, results from these experiments suggested that (1) new orchard soils are ‘biologically suitable’ for planting sweet cherry, and (2) compost application may be a tool to maintain soil health, and mitigate future soil-borne disease in old, replant stress-prone sites, as well as in newly established orchard soils that have never cropped sweet cherry or other tree fruits.

Despite their important time coverage, these observations lack the resolution and positioning given by imaging around visible wavelengths. Amateur observations from Earth have been increasing in quality and coverage since a few years, bringing information on positions, drift rates and shape evolutions of large visible white spots in Saturn's atmosphere. Combining these two complementary sources has brought better analysis of Saturn's storms evolutions.

description: A quantum cascade emitter structure is suggested that is based on electronic transitions in an artificial bandstructure of coupled quantum wires in contrast to the conventional quantum layer systems. The electron transport is normal to the wires in a GaAs/ AlGaAs heterostructure produced by the cleaved-edge overgrowth method. For a realistic system of this type, the relevant rates of radiative transitions and of nonradiative transitions mediated by longitudinal optical phonons have been calculated and have been compared with corresponding data for quantum cascade emitters based on layered structures.

description: The Taupō Volcanic Zone (TVZ) is the southern extent of the Tonga-Kermadec volcanic arc and encompasses the Taupō Rift, with the two structures accommodating extension through the central North Island of New Zealand via magmatic and tectonic processes, respectively. Interplay between components of the TVZ and Taupō Rift are evident at Taupō volcano, which exhibits periods of increased seismicity on a decadal scale. One period of increased seismicity occurred in 2001 outside the caldera in the adjacent Taupō Fault Belt. We use seismological analysis to detect and characterize the Taupō Fault Belt seismicity, which aligns in clusters close to active faults, and was preceded by a large cluster of earthquakes beneath Lake Taupō's Western Bay. This cluster and a temporal change in the local stress field imply that a magmatic intrusion beneath the Western Bay initiated the unrest in the fault belt. Our analysis suggests this intrusion may have occurred outside the silicic reservoir at Taupō and that it represents an example of interaction between the regional tectonic and deep mafic magmatic systems at Taupō.

description: BACKGROUND: A multiple sequence alignment (MSA) generated for a protein can be used to characterise residues by means of a statistical analysis of single columns. In addition to the examination of individual positions, the investigation of co-variation of amino acid frequencies offers insights into function and evolution of the protein and residues. RESULTS: We introduce conn(k), a novel parameter for the characterisation of individual residues. For each residue k, conn(k) is the number of most extreme signals of co-evolution. These signals were deduced from a normalised mutual information (MI) value U(k, l) computed for all pairs of residues k, l. We demonstrate that conn(k) is a more robust indicator than an individual MI-value for the prediction of residues most plausibly important for the evolution of a protein. This proposition was inferred by means of statistical methods. It was further confirmed by the analysis of several proteins. A server, which computes conn(k)-values is available at http://www-bioinf.uni-regensburg.de. CONCLUSION: The algorithms H2r, which analyses MSAs and computes conn(k)-values, characterises a specific class of residues. In contrast to strictly conserved ones, these residues possess some flexibility in the composition of side chains. However, their allocation is sensibly balanced with several other positions, as indicated by conn(k).

We focus on a bottom-up approach where the structure of a higher-dimensional theory arises within ordinary four-dimensional field theory via an appropriate mechanism based on spontaneous symmetry breaking. Subsequently, possible ways to obtain particle physics models with realistic spectrum in this framework are exhibited.

Publisher: name: Targum Association
Year: 1880

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

Sie wurden in besonderer Weise in die verschiedenen politischen Umbruchprozesse in der ersten Hälfte des 20. Jahrhunderts hineingezogen. Obwohl die Akademien von einer konservativen Grundtendenz mit wenig Hang zu Veränderung gekennzeichnet waren, veränderten sich die Einflussmöglichkeiten und das Institutionengefüge. Neben den deutschen Wissenschaftsakademien werden hier auch die Akademien in Österreich und Polen sowie die vielfältige Akademienlandschaft Skandinaviens untersucht. Der Band beschreibt außerdem Innovationsprozesse, etwa die Etablierung der Vertreter neuer Fächer, und den Umgang mit den Erwartungen der Öffentlichkeit. Einen besonderen Schwerpunkt bilden die Jahre der Weimarer Republik und des nationalsozialistischen Regimes in Deutschland. Hier wird der Wandel der Führungsprinzipien am Beispiel der Akademiepräsidenten ausführlich dargestellt und der unwürdige Umgang der Akademien mit ihren jüdischen Mitgliedern aufgearbeitet. Eine weitere Perspektive liefert die Analyse des Wirkens von Akademiemitgliedern, die während der Zeit der NS-Herrschaft und des Zweiten Weltkriegs in Verbrechen verwickelt waren.

description: A GaAs/AlAs superlattice with a large miniband (120 meV) showed self-sustained current oscillation at a frequency of 103 GHz giving rise to microwave emission (power 0.5 mW). The emission line had a linewidth of about 1 MHz and was tuneable by about 800 MHz. An analysis suggests that the transport in the superlattice was mainly due to electrons in the lowest miniband and that the oscillation was caused by traveling dipole domains. We also observed frequency locking of the current oscillation attributed to a synchronization of domain propagation by the external high-frequency field.

description: The evolutionary dynamics of the Public Goods game addresses the emergence of cooperation within groups of individuals. However, the Public Goods game on large populations of interconnected individuals has been usually modeled without any knowledge about their group structure. In this paper, by focusing on collaboration networks, we show that it is possible to include the mesoscopic information about the structure of the real groups by means of a bipartite graph. We compare the results with the projected (coauthor) and the original bipartite graphs and show that cooperation is enhanced by the mesoscopic structure contained. We conclude by analyzing the influence of the size of the groups in the evolutionary success of cooperation.

In this article, Phase II Shewhart-type tr-charts, with various runs rules, are considered for monitoring TBE exponential data with a known rate parameter and the charts’ performance is examined in terms of the average time to signal (ATS). The ATS metric is more suitable due to the possibly unequal times arising between the events. The tr-charts with runs rules are designed so that they are ATS-unbiased for a nominal ATS value. The performance of the proposed charts is compared with that of existing ATS-unbiased tr-charts without runs rules. The proposed charts are found to be more sensitive in detecting small downward and upward shifts. An illustration is provided based on real data, as well as conclusions and some topics for future research.

description: In this paper, a methodology for estimating the Carbon Footprint of a research project is presented. The methodology aims at helping research teams to foresee the impacts of their research on Global Warming. The methodology is intended for research fields in which energy intensity and Greenhouse Gas Emissions (GHGE) are relevant but researchers are not tackling the problem yet. The methodology aligns with the proposals of the European Union for RRI. In addition, it takes advantage of the existing tools for calculating the Carbon Footprint of products, services and processes like PAS 2050 and ISO 14064-II. Finally, it is tailored to the specificities of the research projects. As a case study, it has been applied to a project aiming at developing proposals for promoting the logistics and connections of a Colombian region: Bolívar. The main GHG emissions are estimated to be due to the augment of road transportation and railway transportation of commodities, in the scenario of highest success. In the scenario of moderate success, the GHG emissions of executing the facilities are relevant and comparable with those of the goods transport. The GHG estimations ex-ante based in the methodology allowed introducing corrective measures for improving the environmental requirements of the research to be done.

description: This article is concerned with the testing complete independence for the elements of observed vector. Schott proposed the testing statistic T and gave limiting null distribution under the high-dimensional asymptotic framework that the sample size n and the dimensionality p go to infinity together while p/n converges to a positive constant. In this article we give a one-term asymptotic expansion of the null distribution for T as min{n,p} tends toward infinity. We derive a correction of the critical point for Schott’s test based on this expansion. The finite sample size and dimensionality performance for attained significance level is evaluated in a simulation study and the results are compared to those of Schott’s test.
Determining the role of hyaluronan as an environmental cue for macrophages and dendritic cells

description: CD44 is a cell surface glycoprotein that binds to hyaluronan (HA), an extracellular matrix glycosaminoglycan. Immune cells widely express CD44, but only a few types of cells such as alveolar macrophages (AMФ) in the lung alveoli bind fluorescein-conjugated HA constitutively. During inflammation and immune responses, other immune cells such as monocytes are activated and can gain the ability to bind HA. However, the functional significance of CD44 and HA interactions remains unclear. Therefore, the aim of this study was to investigate the function of CD44 and HA binding and how they regulate immune cells such as AMФ in the tissue environment. HA has been described as a regulator of tissue inflammation, with HA fragments reported to stimulate immune cells. To test if HA fragments can induce inflammation or are consequences of inflammation, I stimulated macrophages and dendritic cells with various sizes of HA from different sources. Pharmaceutical grade HA and endotoxin-free HA fragments failed to stimulate an inflammatory response in vitro and in vivo, demonstrating they were not pro-inflammatory. Since AMФ constitutively bind HA, I then compared these cells from CD44+/+ and CD44-/- mice to study the role of CD44 and HA binding as regulatory environmental cues. Using adoptive transfer experiments and a mouse model of inflammation, I found CD44 expression and HA binding were required for the survival of mature AMФ, but not for the recruitment and differentiation of monocytes into AMФ. CD44 expression by AMФ was required for a cell surface HA coat, which maintained AMФ survival and numbers in the lung. Since AMФ are essential for regulating pulmonary surfactant lipid homeostasis, CD44 deficiency and the partial loss of AMФ in CD44-/- mice disrupted lipid homeostasis in their lungs. CD44-/- mice had elevated lung surfactant phosphatidylcholine levels and CD44-/- AMФ exhibited an abnormal phenotype and accumulated cellular lipid droplets. They also suffered greater inflammation caused by oxidized phosphatidylcholine. Thus, CD44 deficiency led to a reduction of AMФ numbers and caused intrinsic defects in AMФ surfactant lipid homeostasis. Together, these results demonstrate a role of CD44 and HA binding in maintaining AMФ and lung homeostasis.

description: We have observed hysteretic behavior associated with spin transitions in the fractional quantum Hall effect (FQHE). Dramatic hysteresis in up and down sweeps of the magnetic field occurs in the vicinity of the spin-polarized to spin-unpolarized transitions in even-numerator FQHE states. The hysteresis is most pronounced at the lowest temperatures and disappears as the temperature is raised. These results suggest that the FQHE states exhibit metastability in close proximity of the spin transitions. We discuss our findings in terms of a recent proposal of ferromagnetlike ordering associated with nearly degenerate Landau levels.

description: The mass assembly of galaxies leaves various imprints on their surroundings, such as shells, streams and tidal tails. The frequency and properties of these fine structures depend on the mechanism driving the mass assembly: e.g. a monolithic collapse, rapid cold-gas accretion followed by violent disk instabilities, minor mergers or major dry / wet mergers. Therefore, by studying the outskirts of galaxies, one can learn about their main formation mechanism. I present here our on-going work to characterize the outskirts of Early-Type Galaxies (ETGs), which are powerful probes at low redshift of the hierarchical mass assembly of galaxies. This work relies on ultra-deep optical images obtained at CFHT with the wide-field of view MegaCam camera of field and cluster ETGs obtained as part of the Atlas-3D and NGVS projects. State of the art numerical simulations are used to interpret the data. The images reveal a wealth of unknown faint structures at levels as faint as 29 mag arcsec-2 in the g-band. Initial results for two galaxies are presented here.

description: Magneto-resistance measurements in narrow single quantum wells show very sharp (width ≈0.2 T) maxima at fractional filling factors between 1 and Image . The peak values of the new maxima exceed the resistance values in the surrounding magnetic field region by a factor of up to 3. The formation of the maxima is hysteretic and takes place on a long time scale. This points towards a close relation with the nuclear spins. Those new maxima will be discussed in the framework of domains having two different spin ground states.

description: Advergames is a technique that marketers construct purposely for advertising promotion combining video games and entertainment. The purpose of this quasi-experimental research was to examine the relationship between advergame play and purchase intention for players at an academic institution under the AIDA theory model. The general problem is a lack of knowledge regarding the relationship effect of advergames and purchase intentions of players studied under the theoretical framework of the AIDA. There are limited studies on purchase intention with advergames. In this two part study, the researcher quantitatively assessed the relationship between advergame playing and the player‟s purchasing intention within the construct of the AIDA model through an online survey (advertising platform). The researcher quantitatively assessed the relationship between which aspect of the AIDA model is different by demographics (decision making platform). The study population (N= 226) were students attending college in the Northeast, United States. This researcher used Chi -square tests of association and logistic regression to answer and test the research questions and hypotheses. Findings indicated that age, gender, previous viewing experience, and gaming experience do not influence purchase intentions or the AIDA model in participants, but that interactive effects exist, with younger and male students being more likely to intend to purchase, and with combined and interactive effects of age, gender, and previous viewing experience appearing on the awareness, attention, motivation, and action stages of the AIDA model. Additionally, higher levels of Action corresponded to an increased likelihood of purchasing. The findings of this study added to the body of knowledge and could serve as a foundation for advergame design. Keywords: Advergames, Marketing, AIDA,
