description: Depth is a complexity measure for natural systems of the kind studied in statistical physics and is defined in terms of computational complexity. Depth quantifies the length of the shortest parallel computation required to construct a typical system state or history starting from simple initial conditions. The properties of depth are discussed and it is compared to other complexity measures. Depth can only be large for systems with embedded computation.

description: The Virtual Observatory (VO) is becoming the de-facto standard for astronomical data publication. However, the number of radio astronomical archives is still low in general, and even lower is the number of radio astronomical data available through the VO. In order to facilitate the building of new radio astronomical archives, easing at the same time their interoperability with VO framework, we have developed a VO-compliant data model which provides interoperable data semantics for radio data. That model, which we call the Radio Astronomical DAta Model for Single-dish (RADAMS) has been built using standards of (and recommendations from) the International Virtual Observatory Alliance (IVOA). This article describes the RADAMS and its components, including archived entities and their relationships to VO metadata. We show that by using IVOA principles and concepts, the effort needed for both the development of the archives and their VO compatibility has been lowered, and the joint development of two radio astronomical archives have been possible. We plan to adapt RADAMS to be able to deal with interferometry data in the future.

description: El origen de las Artes Marciales se pierde en las nieblas de la Historia y el mito se entrelaza con la realidad cuando se habla de estos inicios. Según la tradición, las Artes Marciales fueron fundadas por Bodhidharma, monje de origen indio y octavo patriarca del budismo, así como fundador de la forma Zen de este último. Cuenta la leyenda que Bodhidharma en medio de  sus  meditaciones budistas pensó que solamente a  través del  ejercicio mental y espiritual no se podía alcanzar la iluminación, pues el cuerpo, parte vital del ser humano, estaba siendo descuidado. Debido a  esto, el monje desarrolló una serie de movimientos de transmisión de la energía corporal y comenzó a entrenar su cuerpo a la par que su mente y su espíritu.

description: We find that the relative contribution of satellite galaxies accreted at high redshift to the stellar population of the Milky Way's smooth halo increases with distance, becoming observable relative to the classical smooth halo about 15 kpc from the Galactic center. In particular, we determine line-of-sight-averaged [Fe/H] and [alpha/Fe] in the metal-poor main-sequence turnoff (MPMSTO) population along every Sloan Extension for Galactic Understanding and Exploration (SEGUE) spectroscopic line of sight. Restricting our sample to those lines of sight along which we do not detect elements of cold halo substructure (ECHOS), we compile the largest spectroscopic sample of stars in the smooth component of the halo ever observed in situ beyond 10 kpc. We find significant spatial autocorrelation in [Fe/H] in the MPMSTO population in the distant half of our sample beyond about 15 kpc from the Galactic center. Inside of 15 kpc however, we find no significant spatial autocorrelation in [Fe/H]. At the same time, we perform SEGUE-like observations of N-body simulations of Milky Way analog formation. While we find that halos formed entirely by accreted satellite galaxies provide a poor match to our observations of the halo within 15 kpc of the Galactic center, we do observe spatial autocorrelation in [Fe/H] in the simulations at larger distances. This observation is an example of statistical chemical tagging and indicates that spatial autocorrelation in metallicity is a generic feature of stellar halos formed from accreted satellite galaxies.

Índice de Calidad del Empleo en Colombia

description: Con el fin de saber cuál es la calidad del empleo para los asalariados en Colombia, este estudio propone una medición para conocerla a partir de la construcción de un Índice de Calidad del Empleo (ICE) con cinco dimensiones y ponderaciones ad hoc: condiciones de trabajo que se refiere a la calidad intrínseca del trabajo y contempla el subempleo por insuficiencia de horas, cualificación y formación que concierne a las oportunidades de mejora, prestaciones salariales, protección social y combinación de trabajo y vida cotidiana que captura la compatibilidad del trabajo con la vida familiar.La propuesta de este índice utiliza un enfoque objetivo de calidad del empleo, es decir, pretende obtener medidas de la calidad del empleo utilizando atributos de los puestos de trabajo, excluyendo las circunstancias personales del trabajador y del mercado laboral; va más allá de lo importantes que son las emociones y percepciones como medidas de bienestar de los trabajadores, además de que estas no son constitutivas de calidad del empleo porque no se corresponden necesariamente con la satisfacción de necesidades (Arranz et al., 2016). Se usan los datos de la Gran Encuesta Integrada de Hogares y la metodología que se sigue es la de Arranz et al. (2016) en un estudio similar que realizaron para el mercado laboral de España, en el cual, para recodificar las variables, a cada componente y subcomponente se le asigna un peso y se recodifican con una métrica lógica  de lo deseable que es cada atributo en términos de calidad. El principal hallazgo en los resultados del índice sintético es que los asalariados de Colombia tienen una calidad media del empleo de 58,3 puntos para 2019 y de 58,6 puntos para 2020, con un aumento interanual de 0,3 puntos lo que significa una mejora muy leve de un año a otro en este índice general. Este resultado podría evidenciar el trabajo en política pública que se ha hecho recientemente por mejorar las condiciones laborales, ya que todas las mediciones previas que se han hecho para Colombia se han caracterizado por tener baja calidad en el empleo. No obstante, no es suficiente para resultar en una mejora significativa de la calidad del empleo para los trabajadores y trabajadoras.Con los resultados obtenidos se brinda una medición reciente y/o actualizada de la calidad del empleo en Colombia para 2019 y 2020. Así mismo, este índice es sencillo, comprensible y comparable, puede medirse para un periodo temporal largo, puede actualizarse con una periodicidad anual, permite la comparación entre grupos de asalariados, tiene cobertura nacional y mide la calidad del empleo a nivel urbano y rural.Al final del documento se encuentra una sección con las conclusiones de este estudio y una discusión sobre las limitaciones de este indicador de calidad, con el fin de informar futuras investigaciones o coadyuvar al desarrollo del mismo indicador.
The Non-Nilpotent Graph of a Semigroup

description: We associate a graph ${\mathcal N}_{S}$ with a semigroup $S$ (called the upper non-nilpotent graph of $S$). The vertices of this graph are the elements of $S$ and two vertices are adjacent if they generate a semigroup that is not nilpotent (in the sense of Malcev). In case $S$ is a group this graph has been introduced by A. Abdollahi and M. Zarrin and some remarkable properties have been proved. The aim of this paper is to study this graph (and some related graphs, such as the non-commuting graph) and to discover the algebraic structure of $S$ determined by the associated graph. It is shown that if a finite semigroup $S$ has empty upper non-nilpotent graph then $S$ is positively Engel. On the other hand, a semigroup has a complete upper non-nilpotent graph if and only if it is a completely simple semigroup that is a band. One of the main results states that if all connected ${\mathcal N}_{S}$-components of a semigroup $S$ are complete (with at least two elements) then $S$ is a band that is a semilattice of its connected components and, moreover, $S$ is an iterated total ideal extension of its connected components. We also show that some graphs, such as a cycle $C_{n}$ on $n$ vertices (with $n\geq 5$), are not the upper non-nilpotent graph of a semigroup. Also, there is precisely one graph on 4 vertices that is not the upper non-nilpotent graph of a semigroup with 4 elements. This work also is a continuation of earlier work by Okniński, Riley and the first named author on (Malcev) nilpotent semigroups.

Gap opening beyond dead zones by photoevaporation

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: We propose a new hypothesis for the origin of protoplanetary discs with large inner holes (or gaps), so-called transition discs. Our gas disc model takes into account layered accretion, in which poorly-ionized low-viscosity dead zones are sandwiched by high-viscosity surface layers, and photoevaporative winds induced by X-rays from the central stars. We find that a gap opens at a radius outside a dead zone, if the mass loss rate due to photoevaporative winds exceeds the mass accretion rate in the dead zone region. Since the dead zone survives even after the gap opens, mass accretion onto the central star continues for a long time. This model can reproduce large gap sizes and high mass accretion rates seen in observed transition discs.

description: We observed the Sh 2-233IR (S233IR) region with better sensitivity in near-infrared than previous studies for this region. By applying statistical subtraction of the back- ground stars, we identified member sources and derived the age and mass of three distinguishable sub-groups in this region: Sh 2-233IR NE, Sh 2-233IR SW, and the "distributed stars" over the whole cloud. Star formation may be occurring sequentially with a relatively small age difference (\sim 0.2-0.3 Myrs) between subclusters. We found that the slopes for initial mass function (Gamma \sim -0.5) of two subclusters are flatter than that of Salpeter, which suggests that more massive stars were preferentially formed in those clusters compared to other Galactic star-forming regions. These subclusters may not result from the overall collapse of the whole cloud, but have formed by triggering before the previous star formation activities disturbed the natal molecular cloud. Addi- tionally, high star formation efficiency (&40%) of the subclusters may also suggest that stars form very efficiently in the center of NE.

description: At the interface of electrostatic potential kink profiles one dimensional chiral states are found in bilayer graphene (BLG). Such structures can be created by applying an asymmetric potential to the upper and the lower layer of BLG. We found that: i) due to the strong confinement by the single kink profile the uni-directional states are only weakly affected by a magnetic field, ii) increasing the smoothness of the kink potential results in additional bound states which are topologically different from those chiral states, and iii) in the presence of a kink-antikink potential the overlap between the oppositely moving chiral states results in the appearance of crossing and anti-crossing points in the energy spectrum. This leads to the opening of tunable minigaps in the spectrum of the uni-directional topological states.

 Remarks. The males of the above material have a forewing mean length of 10.75 mm (10–11 mm); forewing mean length of females was 12.75 mm (11.5 to 14 mm). This species is yellowish with two brownish stripes laterally on the pronotum. Wings have brownish subcostal veins. The color pattern of the head and pronotum of the specimens collected in Macaé agrees with the description of Jewett (1960). However, these specimens do not have the lighter window on the distal part of the wing, which is a common characteristic of A. subcostalis. The penial armature is identical to that described by Froehlich (2004).

Abelian Non-Global Logarithms from Soft Gluon Clustering

description: Most recombination-style jet algorithms cluster soft gluons in a complex way. This leads to correlations in the soft gluon phase space and introduces logarithmic corrections to jet cross sections. The leading Abelian clustering logarithms occur at least at next-to leading logarithm (NLL) in the exponent of the distribution, and we show that new clustering effects contributing at NLL likely arise at each order. Therefore we find that it is unlikely that clustering logs can be resummed to NLL. Clustering logarithms make the anti-kT algorithm theoretically preferred, for which they are power suppressed. They can arise in Abelian and non-Abelian terms, and we calculate the Abelian clustering logarithms at two loops for the jet mass distribution using the Cambridge/Aachen and kT algorithms, including jet radius dependence, which extends previous results. We find that previously identified logarithms from clustering effects can be naturally thought of as a class of non-global logarithms (NGLs), which have traditionally been tied to non-Abelian correlations in soft gluon emission.

description: In this short review we present the developments over the last 5 decades that have led to the use of Graphics Processing Units (GPUs) for astrophysical simulations. Since the introduction of NVIDIA's Compute Unified Device Architecture (CUDA) in 2007 the GPU has become a valuable tool for N-body simulations and is so popular these days that almost all papers about high precision N-body simulations use methods that are accelerated by GPUs. With the GPU hardware becoming more advanced and being used for more advanced algorithms like gravitational tree-codes we see a bright future for GPU like hardware in computational astrophysics.

BR, RJ, Engenheiro Passos, 4 males, BR-485, km-11 Hotel Fazenda Palmital, 26.iv.2007, JAR & F.F. Xavier.
 Remarks. This species was described by Froehlich (2002) based on a single specimen collected in Nova Friburgo, Rio de Janeiro State. In the specimens studied above, the mean length of the forewings of the males is 11.25 mm (10–12 mm) and females 16 mm (15–17 mm). Anacroneuria flintorum has been recorded in streams of the mountainous regions of southeastern and southern Brazil (Froehlich, 2002; Bispo & Froehlich, 2004a). This brown species exhibits much variability in color pattern (Bispo & Froehlich, 2004a). However, the penial armature of all specimens examined is elongated and has hooks well separated from the vesicles, agreeing with the original description of A. flintorum (Froehlich, 2002).

description: We theoretically study the properties of Nambu-Goldstone bosons in an interacting single-component Bose-Einstein condensate (BEC). We first point out that the proofs of Goldstone's theorem by Goldstone, et al. [Phys. Rev. {\bf 127} (1962) 965] may be relevant to distinct massless modes of the BEC: whereas the first proof deals with the poles of the single-particle Green's function $\hat{G}$, the second one concerns those of the two-particle Green's function. Thus, there may be multiple Nambu-Goldstone bosons even in the single-component BEC with broken U(1) symmetry. The second mode turns out to have an infinite lifetime in the long-wavelength limit in agreement with the conventional viewpoint. In contrast, the first mode from $\hat{G}$, i.e., the Bogoliubov mode in the weak-coupling regime, is shown to be a "bubbling" mode fluctuating temporally out of and back into the condensate. The substantial lifetime originates from an "improper" structure of the self-energy inherent in the BEC, which has been overlooked so far and will be elucidated here, and removes various infrared divergences pointed out previously.

description: We report the observation of two narrow structures in the mass spectra of the pi+-Y(nS) (n=1,2,3) and pi+-hb(mP)(m$ (m=1,2) pairs that are produced in association with a single charged pion in Y(5S) decays. The measured masses and widths of the two structures averaged over the five final states are M_1=(10607.2+-2.0) MeV/c2, Gamma_1=(18.4+-2.4) MeV and M_2=(10652.2+-1.5) MeV/c2, Gamma_2=(11.5+-2.2) MeV. The results are obtained with a 121.4 1/fb data sample collected with the Belle detector in the vicinity of the Y(5S) resonance at the KEKB asymmetric-energy e+e- collider.

description: The overall objective of FAIRsFAIR is to accelerate the realization of the goals of the EOSC by opening up and sharing all knowledge, expertise, guidelines, implementations, new trajectories, courses and education on FAIR matters. To support this, FAIRsFAIR is tasked to set up a single FAIR Data Stewardship Competence Centre which this report defines as a shared hub of expertise in implementing FAIR data stewardship principles, offering leadership, coordination and cataloging services to connect relevant people, guidance, learning resources and curricula in different thematic areas. Requirements for competence centres in general and a core competence centre for FAIR data stewardship in general were identified by interviewing other members of the FAIRsFAIR project to understand their expectations for a core competence centre as well as the resources they will contribute to the knowledge base. Furthermore, we carried out a broad characterisation of current competence centres enriched with case studies of good examples for certain aspects of a competence centre. We created user stories for how stakeholders might interact with the competence centres and refined them through an open consultation answered by 106 people, interviews with EOSC clusters, and feedback gathered in workshops at the Open Science Fair 2019. Based on the description of work and our research, we have identified the following priorities for competence centres in general and the FAIRsFAIR core Competence Centre in particular: Advisory Create a catalogue of resources to support FAIR data stewardship Provide a help desk to support FAIR data stewardship Provide a networking tool to support FAIR data stewardship Harmonisation Apply emerging standards to describe learning resources in FAIR data stewardship Encourage economy of scale through deploying the same tools and certifying services addressing FAIR data needs Dissemination Develop training and guidance materials on FAIR data stewardship topics currently not covered Develop curation policies for the content aggregated and developed by the FAIRsFAIR Data Stewardship Competence Centre Deliver training on core competencies for FAIR data stewardship

Renegade Subhaloes in the Local Group

description: Using a dark matter only Constrained Local UniversE Simulation (CLUES) we examine the existence of subhaloes that change their affiliation from one of the two prominent hosts in the Local Group (i.e. the Milky Way and the Andromeda galaxy) to the other, and call these objects "renegade subhaloes". In light of recent claims that the two Magellanic Clouds (MCs) may have originated from another region (or even the outskirts) of the Local Group or that they have been spawned by a major merger in the past of the Andromeda galaxy, we investigate the nature of such events. However, we cannot confirm that renegade subhaloes enter as deep into the potential well of their present host nor that they share the most simplest properties with the MCs, namely mass and relative velocity. Our simulation rather suggests that these renegade subhaloes appear to be flying past one host before being pulled into the other. A merger is not required to trigger such an event, it is rather the distinct environment of our simulated Local Group facilitating such behavior. Since just a small fraction of the full z=0 subhalo population are renegades, our study indicates that it will be intrinsically difficult to distinguish them despite clear differences in their velocity, radial distribution, shape and spin parameter distributions.

description: Anacroneuria itatiaiensis sp. n.
Figs. 6–10
 Material. Holotype male, Brazil, RJ, PNI, Rio Campo Belo; 23.xi.2001, RWH, RJB, HP.
 Description. General color brown; front brown with M-line and side of the ocelli ochraceous (Fig. 6); postfrontal line U-shaped; compound eyes and ocelli black; antennae brown; labial palpi ochraceous; maxillary palpi brownish. Pronotum brown with median band and rugosities lighter (Fig. 6). Legs brownish with lighter femur. Membrane and veins of the wings light brown. Abdomen yellowish. Cerci light brown. Male. Forewing length 10 mm. Hammer conical (Fig. 7). Penial armature elongated, with a pair of relatively small distal membranous vesicles and with a strong subapical constriction in lateral view (Figs. 8–10); hooks long, regularly curved and with pointed apex (Fig. 10); prominent keel in lateral view (Fig. 9); apex of armature slightly curved dorsally (Fig. 9).
 Female. Unknown
 Remarks. Anacroneuria itatiaiensis and A. fuscicosta (Enderlein 1909) are similar in color and wing length, but are distinguished by the differences in details of the penial armature and in size of hammer (shorter in A. itatiaiensis). In dorsal view, the apex of penial armature is pointed in A. itatiaiensis and rounded in A. fuscicosta. In lateral view, the penial armature of A. itatiaiensis has a strong subapical constriction, which is less pronounced in A. fuscicosta.
 Etymology. The specific epithet is formed from Itatiaia, name of the Park where the specimen was collected.

Task-dependent control of open quantum systems

description: We develop a general optimization strategy for performing a chosen unitary or non-unitary task on an open quantum system. The goal is to design a controlled time-dependent system Hamiltonian by variationally minimizing or maximizing a chosen function of the system state, which quantifies the task success (score), such as fidelity, purity, or entanglement. If the time-dependence of the system Hamiltonian is fast enough to be comparable or shorter than the response-time of the bath, then the resulting non-Markovian dynamics is shown to optimize the chosen task score to second order in the coupling to the bath. This strategy can protect a desired unitary system evolution from bath-induced decoherence, but ca also take advantage of the system-bath coupling so as to realize a desired non-unitary effect on the system.

Universal quantum computation with little entanglement
Creators: name: Nest, Maarten Van den
Publisher: name: arXiv
Year: 2012
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We show that universal quantum computation can be achieved in the standard pure-state circuit model while, at any time, the entanglement entropy of all bipartitions is small---even tending to zero with growing system size. The result is obtained by showing that a quantum computer operating within a small region around the set of unentangled states still has universal computational power, and by using continuity of entanglement entropy. In fact an analogous conclusion applies to every entanglement measure which is continuous in a certain natural sense, which amounts to a large class. Other examples include the geometric measure, localizable entanglement, smooth epsilon-measures, multipartite concurrence, squashed entanglement, and several others. We discuss implications of these results for the believed role of entanglement as a key necessary resource for quantum speed-ups.
Discovery of the Host Cluster for the Fundamental Cepheid Calibrator Zeta Gem

description: New and existing CORAVEL, UBVJHKs, HST, HIP/Tycho, ARO, KPNO, and DAO observations imply that the fundamental Cepheid calibrator Zeta Gem is a cluster member. The following parameters were inferred for Zeta Gem from cluster membership and are tied to new spectral classifications (DAO) established for 26 nearby stars (e.g., HD53588/B7.5IV, HD54692/B9.5IV): E(B-V)=0.02+-0.02, log t=7.85+-0.15, and d=355+-15 pc. The mean distance to Zeta Gem from cluster membership and six recent estimates (e.g., IRSB) is d=363+-9(se)+-26(sd) pc. The results presented here support the color-excess and HST parallax derived for the Cepheid by Benedict et al. (2007). Forthcoming precise proper motions (DASCH) and Chandra/XMM-Newton observations of the broader field may be employed to identify cluster members, bolster the cluster's existence, and provide stronger constraints on the Cepheid's fundamental parameters.

 Material examined. Brazil, RJ, Macaé: 1 male, Junção dos Rios Macaé e Bonito, 10.iii.2002, RWH, RJB, HP, ALP.
 Remarks. This species was recently described by Froehlich (2010b) based on material collected in the Serra da Mantiqueira, São Paulo State. This represents the first record of the species in Rio de Janeiro State. In this specimen, the length of the male wing is 10 mm. As described by Froehlich (2010b), this species can be easily confused with A. subcostalis; however, it is darker and its penial armature has a larger apex, which is slightly curved.
