Mixed income housing (MIH)
Mixed Income Housing (MIH) is the outcome of a deliberate effort to build a mixed-income development, usually including a variety of housing typologies, sometime combined with the goal of creating a mixed-tenure development. International consensus on a more specific definition of MIH does not exist; instead, multiple expressions can be equally used, with similar meaning. The expression MIH is mainly used within the USA context where it is sometime replaced by mixed-income neighborhood. In Europe, MIH tend to fall within initiatives on (sustainable) urban regeneration, neighborhood restructuring, urban renewal, while the UK legislation often refers to “pepper-potting” with respect to different tenures in the same neighborhood aimed to achieve MIH. Non-English-speaking countries tend to use different terms.
The MIH policies are challenged by a specific connotation, i.e., in the United States it is the combination between urban poverty and black or Latinos ghettoes; hence, spatial segregation is combined with racial considerations which are less present in other countries, except for South Africa. In the USA, desegregation in public housing estates became a legal obligation following the famous 1969 Gautreaux case, because of the application of the 1964 Civil Rights Act prohibiting racial discrimination in federally funded activities
The Physical and Genetic Framework of the Maize B73 Genome
Maize is a major cereal crop and an important model system for basic biological research. Knowledge gained from maize research can also be used to genetically improve its grass relatives such as sorghum, wheat, and rice. The primary objective of the Maize Genome Sequencing Consortium (MGSC) was to generate a reference genome sequence that was integrated with both the physical and genetic maps. Using a previously published integrated genetic and physical map, combined with in-coming maize genomic sequence, new sequence-based genetic markers, and an optical map, we dynamically picked a minimum tiling path (MTP) of 16,910 bacterial artificial chromosome (BAC) and fosmid clones that were used by the MGSC to sequence the maize genome. The final MTP resulted in a significantly improved physical map that reduced the number of contigs from 721 to 435, incorporated a total of 8,315 mapped markers, and ordered and oriented the majority of FPC contigs. The new integrated physical and genetic map covered 2,120 Mb (93%) of the 2,300-Mb genome, of which 405 contigs were anchored to the genetic map, totaling 2,103.4 Mb (99.2% of the 2,120 Mb physical map). More importantly, 336 contigs, comprising 94.0% of the physical map (∼1,993 Mb), were ordered and oriented. Finally we used all available physical, sequence, genetic, and optical data to generate a golden path (AGP) of chromosome-based pseudomolecules, herein referred to as the B73 Reference Genome Sequence version 1 (B73 RefGen_v1)
Cosmic Shear in Harmonic Space from the Dark Energy Survey Year 1 Data: Compatibility with Configuration Space Results
We perform a cosmic shear analysis in harmonic space using the first year of
data collected by the Dark Energy Survey (DES-Y1). We measure the cosmic weak
lensing shear power spectra using the Metacalibration catalogue and perform a
likelihood analysis within the framework of CosmoSIS. We set scale cuts based
on baryonic effects contamination and model redshift and shear calibration
uncertainties as well as intrinsic alignments. We adopt as fiducial covariance
matrix an analytical computation accounting for the mask geometry in the
Gaussian term, including non-Gaussian contributions. A suite of 1200 lognormal
simulations is used to validate the harmonic space pipeline and the covariance
matrix. We perform a series of stress tests to gauge the robustness of the
harmonic space analysis. Finally, we use the DES-Y1 pipeline in configuration
space to perform a similar likelihood analysis and compare both results,
demonstrating their compatibility in estimating the cosmological parameters
, and . The methods implemented and validated in this
paper will allow us to perform a consistent harmonic space analysis in the
upcoming DES data.Comment: 16 pages, 11 figures. This version matches the published on
Genome of the anaerobic fungus Orpinomyces sp. strain C1A reveals the unique evolutionary history of a remarkable plant biomass degrader
Anaerobic gut fungi represent a distinct early-branching fungal phylum (Neocallimastigomycota) and reside in the rumen, hindgut, and feces of ruminant and nonruminant herbivores. The genome of an anaerobic fungal isolate, Orpinomyces sp. strain C1A, was sequenced using a combination of Illumina and PacBio single-molecule real-time (SMRT) technologies. The large genome (100.95 Mb, 16,347 genes) displayed extremely low G+C content (17.0%), large noncoding intergenic regions (73.1%), proliferation of microsatellite repeats (4.9%), and multiple gene duplications. Comparative genomic analysis identified multiple genes and pathways that are absent in Dikarya genomes but present in early-branching fungal lineages and/or nonfungal Opisthokonta. These included genes for posttranslational fucosylation, the production of specific intramembrane proteases and extracellular protease inhibitors, the formation of a complete axoneme and intraflagellar trafficking machinery, and a near-complete focal adhesion machinery. Analysis of the lignocellulolytic machinery in the C1A genome revealed an extremely rich repertoire, with evidence of horizontal gene acquisition from multiple bacterial lineages. Experimental analysis indicated that strain C1A is a remarkable biomass degrader, capable of simultaneous saccharification and fermentation of the cellulosic and hemicellulosic fractions in multiple untreated grasses and crop residues examined, with the process significantly enhanced by mild pretreatments. This capability, acquired during its separate evolutionary trajectory in the rumen, along with its resilience and invasiveness compared to prokaryotic anaerobes, renders anaerobic fungi promising agents for consolidated bioprocessing schemes in biofuels production.Peer reviewedMicrobiology and Molecular GeneticsBiosystems and Agricultural Engineerin
Installing and configuring CMap
CMap is a Web-based tool for viewing comparisons between biological maps of different types. It allows for correspondences to be displayed between maps as disparate as genetic and physical maps. The protocols in this unit comprise a guide to installing, configuring, and importing data into CMap
Fluid silicone and biologic reactions. Clinical and experimental results
Una revisione della bibliografia mondiale, compiuta recentemente nel nostro Istituto ha posto in evidenza dati riconducibili a due grandi gruppi di ricerche: quelle sperimentali e quelle cliniche. I risultati che ne emergono sono complementari pur partendo da premesse e modalità di sperimentazione a volte anche profondamente diverse
Long-term results of the treatment of cutaneous angiomas
Dopo un breve inquadramento nosologico degli angiomi cutanei, gli AA. passano in rassegna i risultati a distanza dei diversi trattamenti in uso per le forme immature. Pur con le inevitabili sequele e limitazioni connesse con la particolare natura di queste forme patologiche, l’intervento chirurgico appare la terapia più idonea. L’ottimo andamento degli angiomi non sottoposti ad alcuna terapia porta in ogni caso a suggerire la massima cautela nella scelta di qualsiasi protocollo terapeutic
