Deconstructing Red-Black Trees with Bantling

The refinement of DNS has harnessed access points, and current trends suggest that the improvement of reinforcement learning will soon emerge. Here, authors verify the understanding of web browsers, demonstrates the private importance of cyberinformatics. In order to answer this challenge, we validate that despite the fact that multi-processors and vacuum tubes can synchronize to achieve this mis- sion, vacuum tubes and local-area networks can col- laborate to overcome this question

Adaptive significance of small body size under poor socio-economic conditions in southern Peru

The relationship of variations in parental body size to offspring survival has been studied in a population of poor socio-economic conditions (“Barriada”) in the southern highland of Peru. Parents of small body size, especially mothers, had significantly greater per cent offspring survival than parents with larger body size. In other words, the offspring survival effectiveness of subjects of small body size was greater than that of subjects of large body size. It is postulated that the greater offspring survival effectiveness associated with small parental body size may reflect possible adaptive responses to poor socio-economic conditions.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/37538/1/1330390216_ftp.pd

Evaluación de las áreas estratégicas en Pamplona

Con el pasar del tiempo y el rápido avance de la tecnología, el mundo actual está adoptando una tendencia individualista, lo cual solo permite pensar en el “yo”, en las comodidades, olvidando aquellos lugares de los cuales se derivan comodidades como las áreas estratégicas ambientalmente importantes. Este proyecto se llevó a cabo entre la Universidad de Pamplona y la Empresa de servicios públicos del Municipio de Pamplona para evaluar las condiciones actuales de la zona de estudio. Se recolectaron muestras en campo con la implementación de seis parcelas distribuidas en dos niveles altitudinales diferentes, subdividiendose en 5 subparcelas; posteriormente se analizó estadísticamente la cobertura vegetal determinando el índice de diversidad y riqueza, mediante el software PAST; se determinó la dominancia entre las 6 parcelas aun estando en diferentes niveles altitudinales, oscilando entre los valores de 0,1 a 0,2 siendo el más alto 0,168 para la parcela P1-3 estos valores similares definen la no existencia de dominancia; Se aprecia una diversidad atenuada, lo cual lleva a analizar el porqué de estos resultados; si retrocedemos 7 y 10 años en el pasado donde se tenía que las actuales áreas estratégicas eran implementadas para realizar actividades agrícolas con siembra de cultivos: papa, fresa, lechuga, papa criolla, en los cuales se aplicaban insumos químicos: fertilizantes, pesticidas, herbicidas, que han predispuesto el terreno facilitando el desarrollo de un grupo de especies más que las otras; otro factor es que el bosque nativo está a una distancia mayor de 2 km dificultando el transporte de semillas por aves mas no se presenta ausencia de este fenómeno. Se concluye que la zona estudiada ha evolucionado de manera positiva para hoy en día ser un bosque primario estableciendo un clímax de especies

Unveiling a Rich System of Faint Dwarf Galaxies in the Next Generation Fornax Survey

We report the discovery of 158 previously undetected dwarf galaxies in the Fornax cluster central regions using a deep coadded $u, g$ and $i$-band image obtained with the DECam wide-field camera mounted on the 4-meter Blanco telescope at the Cerro Tololo Interamerican Observatory as part of the {\it Next Generation Fornax Survey} (NGFS). The new dwarf galaxies have quasi-exponential light profiles, effective radii $0.1\!<\!r_e\!<\!2.8$ kpc and average effective surface brightness values $22.0\!<\!\mu_i\!<\!28.0$ mag arcsec$^{-2}$. We confirm the existence of ultra-diffuse galaxies (UDGs) in the Fornax core regions that resemble counterparts recently discovered in the Virgo and Coma galaxy clusters.~We also find extremely low surface brightness NGFS dwarfs, which are several magnitudes fainter than the classical UDGs. The faintest dwarf candidate in our NGFS sample has an absolute magnitude of $M_i\!=\!-8.0$\,mag. The nucleation fraction of the NGFS dwarf galaxy sample appears to decrease as a function of their total luminosity, reaching from a nucleation fraction of $>\!75\%$ at luminosities brighter than $M_i\!\simeq\!-15.0$ mag to $0\%$ at luminosities fainter than $M_i\!\simeq\!-10.0$ mag. The two-point correlation function analysis of the NGFS dwarf sample shows an excess on length scales below $\sim\!100$ kpc, pointing to the clustering of dwarf galaxies in the Fornax cluster core.Comment: 6 pages, 3 figures.

The Next Generation Virgo Cluster Survey. X. Properties of Ultra-Compact Dwarfs in the M87, M49 and M60 Regions

We use imaging from the Next Generation Virgo cluster Survey (NGVS) to present a comparative study of ultra-compact dwarf (UCD) galaxies associated with three prominent Virgo sub-clusters: those centered on the massive, red-sequence galaxies M87, M49 and M60. We show how UCDs can be selected with high completeness using a combination of half-light radius and location in color-color diagrams ($u^*iK_s$ or $u^*gz$). Although the central galaxies in each of these sub-clusters have nearly identical luminosities and stellar masses, we find large differences in the sizes of their UCD populations, with M87 containing ~3.5 and 7.8 times more UCDs than M49 and M60, respectively. The relative abundance of UCDs in the three regions scales in proportion to sub-cluster mass, as traced by X-ray gas mass, total gravitating mass, number of globular clusters, and number of nearby galaxies. We find that the UCDs are predominantly blue in color, with ~85% of the UCDs having colors similar to blue GCs and stellar nuclei of dwarf galaxies. We present evidence that UCDs surrounding M87 and M49 may follow a morphological sequence ordered by the prominence of their outer, low surface brightness envelope, ultimately merging with the sequence of nucleated low-mass galaxies, and that envelope prominence correlates with distance from either galaxy. Our analysis provides evidence that tidal stripping of nucleated galaxies is an important process in the formation of UCDs.Comment: 37 pages, 40 figures. To appear in The Astrophysical Journa

Prospective study of urinary tract infection surveillance after kidney transplantation

<p>Abstract</p> <p>Background</p> <p>Urinary tract infection (UTI) remains one of the main complications after kidney transplantation and it has serious consequences.</p> <p>Methods</p> <p>Fifty-two patients with kidney transplantation were evaluated for UTI at 3-145 days (mean 40.0 days) after surgery.. Forty-two received a graft from a live donor and 10 from a deceased donor. There were 22 female and 30 male patients, aged 11-47 years. Microscopic examinations, leukocyte esterase stick, and urinary culture were performed every third day and weekly after hospitalization. A positive culture was consider when patients presented bacterial counts up to 10⁵ counts.</p> <p>Results</p> <p>UTI developed in 19/52 (37%) patients at 3-75 days (mean 19.5 days after transplantation. Recurrent infection was observed in 7/52 (13.4%) patients at days 17-65. UTI was more frequent in patients who received deceased grafts compared with live grafts (7/10, 70% <it>vs</it>. 12/42, 28%; p < 0.007). Female patients were more susceptible than male (11/22, 50% <it>vs</it>. 8/22, 36.35%; p < 0.042). Five-year survival rate was 94.5% (49/52 patients). Kidney Graft exit update is 47/52 (90.2%), and there were no significant differences between graft rejection and UTI (p = 0.2518). Isolated bacteria were <it>Escherichia coli </it>(31.5%), <it>Candida albicans </it>(21.0%) and <it>Enterococcus </it>spp. (10.5%), followed by <it>Pseudomonas aeruginosa, Klebsiella pneumoniae, Morganella </it><it>morganii, Enterobacter cloacae </it>and <it>Micrococcus </it>spp. Secondary infections were produced by (7/19, 36.8%). <it>Enterococcus </it>spp. (57%), <it>E. coli </it>(28%) and <it>Micrococcus </it>spp. (14.2%). Antibiotic resistance was 22% for ciprofloxacin and 33% for ampicillin. Therapeutic alternatives were aztreonam, trimethoprim-sulfamethoxazole, netilmicin and fosfomycin.</p> <p>Conclusions</p> <p>Surveillance of UTI for the first 3 months is a good option for improving quality of life of kidney transplantation patients and the exit of graft function especially for female patients and those receiving deceased grafts. Antibiograms provided a good therapeutic alternative to patients who presented with UTIs after receiving a kidney allograft.</p

A Hybrid Approach to Parallel Pattern Discovery in C++

Funding: EU Horizon 2020 project, TeamPlay, grant number 779882, and UK EPSRC Discovery, grant number EP/P020631/1.Parallel pattern libraries offer a strong combination of abstraction and performance. However, discovering places in sequential code where parallel patterns should be introduced is still highly non-trivial, often requiring expert manual analysis and profiling. We present a hybrid discovery technique to detect instances of parallel patterns in sequential code. This employs both static and dynamic trace-based analysis, together with hotspot detection. We evaluate our pattern discovery mechanism on a number of representative benchmarks. We evaluate the performance of the resulting parallelised benchmarks on a 24-core parallel machine.Postprin

The little-studied cluster Berkeley 90 : I. LS III +46 11: a very massive O3.5 If* + O3.5 If* binary

Context. It appears that most (if not all) massive stars are born in multiple systems. At the same time, the most massive binaries are hard to find owing to their low numbers throughout the Galaxy and the implied large distances and extinctions. Aims. We want to study LS III +46 11, identified in this paper as a very massive binary; another nearby massive system, LS III +46 12; and the surrounding stellar cluster, Berkeley 90. Methods. Most of the data used in this paper are multi-epoch high S/N optical spectra, although we also use Lucky Imaging and archival photometry. The spectra are reduced with dedicated pipelines and processed with our own software, such as a spectroscopic-orbit code, CHORIZOS, and MGB. Results. LS III +46 11 is identified as a new very early O-type spectroscopic binary [O3.5 If* + O3.5 If*] and LS III +46 12 as another early O-type system [O4.5 V((f))]. We measure a 97.2-day period for LS III +46 11 and derive minimum masses of 38.80 ± 0.83 M⊙ and 35.60 ± 0.77 M⊙ for its two stars. We measure the extinction to both stars, estimate the distance, search for optical companions, and study the surrounding cluster. In doing so, a variable extinction is found as well as discrepant results for the distance. We discuss possible explanations and suggest that LS III +46 12 may be a hidden binary system where the companion is currently undetected.Facultad de Ciencias Astronómicas y GeofísicasInstituto de Astrofísica de La Plat
