The Synoptic All-Sky Infrared (SASIR) Survey
We are proposing to conduct a multicolor, synoptic infrared (IR) imaging
survey of the Northern sky with a new, dedicated 6.5-meter telescope at San
Pedro M\'artir (SPM) Observatory. This initiative is being developed in
partnership with astronomy institutions in Mexico and the University of
California. The 4-year, dedicated survey, planned to begin in 2017, will reach
more than 100 times deeper than 2MASS. The Synoptic All-Sky Infrared (SASIR)
Survey will reveal the missing sample of faint red dwarf stars in the local
solar neighborhood, and the unprecedented sensitivity over such a wide field
will result in the discovery of thousands of z ~ 7 quasars (and reaching to z >
10), allowing detailed study (in concert with JWST and Giant Segmented Mirror
Telescopes) of the timing and the origin(s) of reionization. As a time-domain
survey, SASIR will reveal the dynamic infrared universe, opening new phase
space for discovery. Synoptic observations of over 10^6 supernovae and variable
stars will provide better distance measures than optical studies alone. SASIR
also provides significant synergy with other major Astro2010 facilities,
improving the overall scientific return of community investments. Compared to
optical-only measurements, IR colors vastly improve photometric redshifts to z
~ 4, enhancing dark energy and dark matter surveys based on weak lensing and
baryon oscillations. The wide field and ToO capabilities will enable a
connection of the gravitational wave and neutrino universe - with events
otherwise poorly localized on the sky - to transient electromagnetic phenomena.Comment: Revised version of submitted whitepaper to the "Optical and IR

Global urban environmental change drives adaptation in white clover
Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations in 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense that also affects tolerance to abiotic stressors. Urban-rural gradients were associated with the evolution of clines in defense in 47% of cities throughout the world. Variation in the strength of clines was explained by environmental changes in drought stress and vegetation cover that varied among cities. Sequencing 2074 genomes from 26 cities revealed that the evolution of urban-rural clines was best explained by adaptive evolution, but the degree of parallel adaptation varied among cities. Our results demonstrate that urbanization leads to adaptation at a global scale
Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries
Abstract
Background
Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres.
Methods
This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries.
Results
In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia.
Conclusion
This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
Modelo de predicción de la vida útil de la edificación patrimonial a partir de la lógica difusa
We seek a procedure to identify and assess the factors that affect the vulnerability and risks affecting the building and validate a model to calculate service life. We would thus have a prediction method that would be very useful in the process of maintenance and conservation of the built heritage. The problem is that in analyzing the various methods currently used to predict events in the field of heritage conservation, we find that such methods are at the threshold of uncertainty. For this reason, we have chosen to work with the theory of fuzzy sets (fuzzy set), as most appropriate tool. When generated prediction model based mathematics, what we have called FBSL (Fuzzy building service life) and provide satisfactory results, when predicting the building service life.<br><br>Buscamos un procedimiento que permita determinar y valorar los factores que inciden sobre la vulnerabilidad y riesgos que afectan al edificio y validar un modelo para poder calcular su vida útil. Tendríamos así un método de predicción que resultaría de mucha utilidad en los procesos de mantenimiento y conservación del patrimonio edificado. El problema es que al analizar las diversas metodologías que actualmente se utilizan para la predicción de hechos en el campo de la conservación del patrimonio, nos encontramos con que tales métodos se hallan en el umbral de la incertidumbre. Por esta causa, hemos optado por trabajar con la teoría de conjuntos difusos (<em>Fuzzy set</em>), como herramienta más adecuada. Al modelo de predicción generado con base matemática, lo hemos denominado FBSL (<em>Fuzzy building service life</em>) y ofrece unos resultados satisfactorios, a la hora predecir la vida útil del edificio
Cell Volume Homeostatically Controls the rDNA Repeat Copy Number and rRNA Synthesis Rate in Yeast
The adjustment of transcription and translation rates to the changing needs of cells is of utmost importance for their fitness and survival. We have previously shown that the global transcription rate for RNA polymerase II in budding yeast Saccharomyces cerevisiae is regulated in relation to cell volume. Total mRNA concentration is constant with cell volume since global RNApol II-dependent nascent transcription rate (nTR) also keeps constant but mRNA stability increases with cell size. In this paper, we focus on the case of rRNA and RNA polymerase I. Contrarily to that found for RNA pol II, we detected that RNA polymerase I nTR increases proportionally to genome copies and cell size in polyploid cells. In haploid mutant cells with larger cell sizes, the rDNA repeat copy number rises. By combining mathematical modeling and experimental work with the large-size cln3 strain, we observed that the increasing repeat copy number is based on a feedback mechanism in which Sir2 histone deacetylase homeostatically controls the amplification of rDNA repeats in a volume-dependent manner. This amplification is paralleled with an increase in rRNA nTR, which indicates a control of the RNA pol I synthesis rate by cell volume.European Commission (EC).

ART-RISK 3.0 a fuzzy—based platform that combine GIS and expert assessments for conservation strategies in cultural heritage
eritage preservation poses numerous difficulties, especially in emergency situations or during bud get cuts. In these contexts, having tools that facilitate efficient and rapid management of hazards vulnerabilities is a priority for the preventive conservation and triage of cultural assets.
This paper presents the first (to the authors’ knowledge) free and public availability Artificial Intel ligence platform designed for conservation strategies in cultural heritage. Art-Risk 3.0 is a platform de signed as a fuzzy-logic inference system that combines information from geographical information system
maps with expert assessments, in order to identify the contextual threat level and the degree of vulner ability that heritage buildings present. Thanks to the possibilities that the geographic information system
offers, 12 Spanish churches (11th - 16th centuries) were analyzed. The artificial intelligence platform de veloped makes it possible to analyze the index of hazard, vulnerability and functionality, classify build ings according to the risk in order to do a sustainable use of budgets through the rational management
of preventive conservation.
The data stored in the system allows identify the danger due to geotechnics, precipitation, torrential
downpour, thermal oscillation, frost, earthquake and flooding. Through the use of fuzzy logic, the tool
interrelates environmental conditions with 14 other variables related to structural risks and the vulnera bility of buildings, which are evaluated through bibliographic search and review of photographic images.
The geographic information system has identified torrential rains and thermal oscillations as the en vironmental threats that mostly impact heritage buildings in Spain.
The results obtained highlight the Church of Santiago de Jesús as the most vulnerable building due
to a lack of preventive conservation programs. These results, consistent with the inclusion of this mon ument on the list of heritage at risk defined by Hispania Nostra, corroborate the functionality of the
model.Ministerio de Economía y Competitividad BIA2015–64878-RMinisterio de Ciencia, Innovación y Universidades PID2019–107257RB-I00Ministerio de Ciencia e Innovación PTA2019–01688
