Incipient genome erosion and metabolic streamlining for antibiotic production in a defensive symbiont

2021

Significance Genome reduction is commonly observed in bacteria of several phyla engaging in obligate nutritional symbioses with insects. In Actinobacteria, however, little is known about the process of genome evolution, despite their importance as prolific producers of antibiotics and their increasingly recognized role as defensive partners of insects and other organisms. Here, we show that “Streptomyces philanthi,” a defensive symbiont of digger wasps, has a G+C-enriched genome in the early stages of erosion, with inactivating mutations in a large proportion of genes, causing dependency on its hosts for certain nutrients, which was validated in axenic symbiont cultures. Additionally, overe…

Spatial diversity of chlorine residual in a drinking water distribution system: application of an integrated fuzzy logic technique

2014

A reduction in the concentration of chlorine, which is used as a chemical disinfectant for water in drinking water distribution systems, can be considered to be an index of the progressive deterioration of water quality. In this work, attention is given to the spatial distribution of the residual chlorine in drinking water distribution systems. The criterion for grouping the water-quality parameters normally used is highly subjective and often based on data that are not correctly identified. In this paper, a cluster analysis based on fuzzy logic is applied. The advantage of the proposed procedure is that it allows a user to identify (in an automatic way and without any specific assumption) …

Prior Precision Modulates the Minimization of Auditory Prediction Error

2019

International audience; The predictive coding model of perception proposes that successful representation of the perceptual world depends upon canceling out the discrepancy between prediction and sensory input (i.e., prediction error). Recent studies further suggest a distinction to be made between prediction error triggered by non-predicted stimuli of different prior precision (i.e., inverse variance). However, it is not fully understood how prediction error with different precision levels is minimized in the predictive process. Here, we conducted a magnetoencephalography (MEG) experiment which orthogonally manipulated prime-probe relation (for contextual precision) and stimulus repetition…

"Nach Wien möchte ich auch gern einmal" – Ricarda Huchs Österreichbilder

2018

The following article presents an image of historical, aesthetical and social space of Austria from the perspective of Ricarda Huch. For Huch, a doctor of history, writer, thinker and a personality of literary life, Austria was almost a lifelong point of reference for her views as an intellectual, it also had an impact on her interpersonal contacts. The writer, who after 1933 lived in an internal emigration, in the history of Austrian statehood finds references to the possibility of expressing opposition coming from the moral responsibility of an individual and then directed against all manifestations of enslavement.

Eredità della musica. David J.Bach e i concerti dei lavoratori viennesi (1905-1934)

2007

E' un'idea largamente diffusa che la Grande Vienna sia stato uno dei cruciali laboratori del Novecento.Questo studio della Vienna tra fine Ottocento e avvento nazista, che mette assieme la storia, la storia della musica e la musicologia, la storia della cultura e quella sociale, lo riafferma. Ma lo riconsidera, guardandolo dalla prospettiva di una esperienza particolare. Si tratta del grandioso tentativo, da parte della socialdemocrazia e dei teorici dell'austromarxismo di fare del proletariato l'erede della tradizione musicale viennese, e attraverso questo, erede della cultura classica tedesca.

Space-VLBI phase-reference mapping and astrometry

2001

We present 5 GHz space-VLBI observations of the quasar pair B1342+662/B1342+663 that demonstrate the feasibility of phase-reference techniques using an antenna in space. The space-based data were taken by the satellite HALCA, of the space-VLBI mission VSOP. From residual (referenced) phases we derive an upper bound of 10 meters to the uncertainty of the spacecraft orbit reconstruction. An analysis of the phase-reference maps of the sources additionally suggests that the above mentioned uncertaintyis likely not larger than 3 meters. With errors of this magnitude, HALCA is a useful tool for astrometric studies of close pairs of radio sources.

Passive RFID Strain-Sensor Based on Meander-Line Antennas

2011

The processing of backscattered signals coming from RFID tags is potentially useful to detect the physical state of the tagged object. It is here shown how to design a completely passive UHF RFID sensor for strain monitoring starting from a flexible meander-line dipole whose shape factor and feed section are engineered to achieve the desired sensing resolution and dynamic range. This class of devices is low-cost, promises sub-millimeter resolution and may found interesting applications in the Structural Health Monitoring of damaged structures and vehicles as well as during extreme and adverse events.
