En la actualidad se ha producido un considerable esfuerzo para desarrollar algoritmos que comparan las secuencias de macromoléculas biológicas (proteínas, ADN y ARN), cuyo objetivo es detectar las relaciones evolutivas tanto estructurales como funcionales. Este es el principal problema de la biología computacional, estas tareas se llevan a cabo, actualmente, por las herramientas de la bioinformática que han sido desarrolladas con algoritmos secuenciales. La programación dinámica, tanto los algoritmos de alineamiento locales (Smith-Waterman) y alineamiento global (Needleman-Wunsch) determinan el alineamiento óptimo de dos secuencias. Actualmente, las computadoras que tienen más de un núcleo están disponibles para el usuario común, y para usar los múltiples procesadores de la computadora, es necesario conocer los paradigmas de programación paralela. Este trabajo, presenta una nueva propuesta algorítmica para el alineamiento global usando la programación paralela, esto requiere de una nueva reformulación del algoritmo de Needleman Wunsh. La implementación del Algoritmo Paralelo ha requerido hacer un llenado de la matriz de scores por sus antidiagonales con todos los procesadores disponibles. El software utilizado para ello fue el C# con la librería TPL (“Task Parallel Library”), la aplicación compara el algoritmo de Needleman- Wunsch con este nuevo algoritmo, comprobando los tiempos de respuesta. Los resultados muestran que el algoritmo paralelo propuesto reduce el tiempo de respuesta en comparación con el algoritmo de alineamiento global de Needleman-Wunsch.

Da câmara subjetiva à falsa objetividade das imagens no cinema: apontamentos sobre duas experiências limite
Authors: Tavares Mirian 
Published: June 2019

Através da análise de um aspeto morfológico do dispositivo cinematográfico, a câmara subjetiva, procuro apresentar modelos divergentes de utilização do cânone e processos alternativos de projeção/identificação pela imagem. O recurso à câmara subjetiva está associado, geralmente, a momentos de grande tensão quando se espera uma maior aderência do espectador ao ecrã : vemos através dos olhos das personagens e assim aumenta a sensação de envolvimento, e de presença, do filme em nós e de nós mesmos dentro do espaço diegético. Raramente a câmara subjetiva é /foi utilizada durante todo o filme, apagando assim o corpo das personagens do ecrã, porque se sabe que o mundo das imagens é o mundo da sedução e do reconhecimento que se dá pelo corpo projetado, e idealizado, que se (im) põe ao nosso olhar. Não nos podemos esquecer devque a imagem do ecrã é um constructo ideológico que faz parte da tradição artística ocidental. Os artistas do início do século XX pretenderam desmistificar o cânon e demonstrar que tudo na arte era sempre fruto de uma construção. Este modelo de representação, negado pelas vanguardas, foi absorvido pela fotografia e pelo cinema e, apesar dos discursos divergentes que hoje atravessam o discurso canônico ocidental, ainda perduram reproduções e replicações deste modelo, dentro e fora do espaço europeu.

Fast Inversion of Solar Ca ii Spectra in Non-local Thermodynamic Equilibrium
Authors: Beck C. , Gosain S. , Kiessner C. 
Published: June 2019

Abstract
Present-day solar imaging spectrometers typically yield a few hundred million spectra in one hour of observing time. This number will increase by an order of magnitude for future instruments with larger 4k × 4k sensors, such as those planned to be used for the upcoming Daniel K. Inouye Solar Telescope. A fast quantitative analysis of such huge data volumes can be done by comparing the observations to an archive of pre-calculated synthetic spectra to infer the thermodynamic properties of the atmosphere. To analyze intensity spectra of the Ca ii IR line at 854 nm in the solar atmosphere, we generated an archive with 2,000,000 spectra under the assumption of non-local thermodynamic equilibrium (NLTE) with the NICOLE code. We tested its performance by inverting 60 spectral scans of Ca ii IR at 854 nm in the magnetically quiet Sun with 700,000 profiles each. Based on the inversion results obtained using the full archive, we constructed a smaller archive by keeping only the 70,000 archive profiles that were actually used. We can reproduce the observed intensity spectra to within a few percent using either the full or the small archive. For spectra with 30 wavelength points, this NLTE inversion approach takes 0.02 (0.35) s per profile to obtain a temperature stratification when using the small (full) archive, i.e., it can invert a single spectral scan in about 4 (68) hr. The code is able to simultaneously deal with an arbitrary number of spectral lines. This makes it a promising tool for deriving thermodynamic properties of the solar atmosphere from current or future solar high-resolution observations of photospheric and chromospheric lines.
New Very Local Interstellar Spectra for Electrons, Positrons, Protons, and Light Cosmic Ray Nuclei
Authors: Bisschoff D. , Potgieter M. S. , Aslam O. P. M. 
Published: June 2019

Abstract
The local interstellar spectra (LISs) for galactic cosmic rays (CRs) cannot be directly observed at the Earth below certain energies, because of solar modulation in the heliosphere. With Voyager 1 crossing the heliopause in 2012, in situ experimental LIS data below 100 MeV/nuc can now constrain computed galactic CR spectra. Using galactic propagation models, galactic electron, proton, and light nuclei spectra can now be computed more reliably as LISs. Using the Voyager 1 observations made beyond the heliopause, and the observations made by the PAMELA experiment in Earth orbit for the 2009 solar minimum, as experimental constraints, we simultaneously reproduced the CR electron, proton, helium, and carbon observations by implementing the GALPROP code. Below about 30 GeV/nuc solar modulation has a significant effect and a comprehensive three-dimensional (3D) numerical modulation model is used to compare the computed spectra with the observed PAMELA spectra at these energies. Subsequently the computed LISs can be compared over as wide a range of energies as possible. The simultaneous calculation of CR spectra with a single propagation model allows the LISs for positrons, boron, and oxygen to also be inferred. This implementation of the comprehensive galactic propagation model (GALPROP), alongside a sophisticated solar modulation model to compute CR spectra for comparison with both Voyager 1 and PAMELA observations over a wide energy range, allows us to present new self-consistent LISs (and expressions) for electrons, positrons, protons, helium, carbon, boron, and oxygen for the energy range of 3 MeV/nuc–100 GeV/nuc.
The MASSIVE Survey XIII. Spatially Resolved Stellar Kinematics in the Central 1 kpc of 20 Massive Elliptical Galaxies with the GMOS-North Integral Field Spectrograph
Authors: Ene Irina , Ma Chung-Pei , McConnell Nicholas J. , Walsh Jonelle L. , Kempski Philipp , Greene Jenny E. , Thomas Jens , Blakeslee John P. 
Published: June 2019

Abstract
We use observations from the GEMINI-N/GMOS integral field spectrograph (IFS) to obtain spatially resolved stellar kinematics of the central ∼1 kpc of 20 early-type galaxies (ETGs) with stellar masses greater than 1011.7
M
⊙ in the MASSIVE survey. Together with observations from the wide-field Mitchell IFS at McDonald Observatory in our earlier work, we obtain unprecedentedly detailed kinematic maps of local massive ETGs, covering a scale of ∼0.1–30 kpc. The high (∼120) signal-to-noise ratio of the GMOS spectra enables us to obtain two-dimensional maps of the line-of-sight velocity and velocity dispersion σ, as well as the skewness h
3 and kurtosis h
4 of the stellar velocity distributions. All but one galaxy in the sample have σ(R) profiles that increase toward the center, whereas the slope of σ(R) at one effective radius (R

e
) can be of either sign. The h
4 is generally positive, with 14 of the 20 galaxies having positive h
4 within the GMOS aperture and 18 having positive h
4 within 1R

e
. The positive h
4 and rising σ(R) toward small radii are indicative of a central black hole and velocity anisotropy. We demonstrate the constraining power of the data on the mass distributions in ETGs by applying Jeans anisotropic modeling (JAM) to NGC 1453, the most regular fast rotator in the sample. Despite the limitations of JAM, we obtain a clear χ
2 minimum in black hole mass, stellar mass-to-light ratio, velocity anisotropy parameters, and circular velocity of the dark matter halo.
Physics of Luminous Transient Light Curves: A New Relation between Peak Time and Luminosity
Authors: Khatami David K. , Kasen Daniel N. 
Published: June 2019

Abstract
Simplified analytic methods are frequently used to model the light curves of supernovae and other energetic transients and to extract physical quantities, such as the ejecta mass and amount of radioactive heating. The applicability and quantitative accuracy of these models, however, have not been clearly delineated. Here we carry out a systematic study comparing certain analytic models to numerical radiation transport calculations. We show that the neglect of time-dependent diffusion limits the accuracy of common Arnett-like analytic models, and that the widely applied Arnett’s rule for inferring radioactive mass does not hold in general, with an error that increases for models with longer diffusion times or more centralized heating. We present new analytic relations that accurately relate the peak time and luminosity of an observed light curve to the physical ejecta and heating parameters. We further show that recombination and spatial distribution of heating modify the peak of the light curve and that these effects can be accounted for by varying a single dimensionless parameter in the new relations. The results presented should be useful for estimating the physical properties of a wide variety of transient phenomena.

Abstract
We present Atacama Large Millimeter/submillimeter Array 97.5 GHz total intensity and linear polarization observations of the mm-band afterglow of GRB 190114C spanning 2.2–5.2 hr after the burst. We detect linear polarization at the ≈5σ level, decreasing from Π = (0.87 ± 0.13)% to (0.60 ± 0.19)%, and evolving in polarization position angle from (10 ± 5)° to (−44 ± 12)° during the course of the observations. This represents the first detection and measurement of the temporal evolution of polarized radio/millimeter emission in a γ-ray burst. We show that the optical and X-ray observations between 0.03 days and ∼0.3 days are consistent with a fast-cooling forward shock expanding into a wind environment. However, the optical observations at ≲0.03 days, as well as the radio and millimeter observations, arise from a separate component, which we interpret as emission from the reverse-shocked ejecta. Using the measured linear polarization, we constrain the coherence scale of tangled magnetic fields in the ejecta to an angular size of θ
B ≈ 10−3 radian, while the rotation of the polarization angle rules out the presence of large-scale, ordered axisymmetric magnetic fields, and in particular a large-scale toroidal field, in the jet.
