Explaining Adaptation in Genetic Algorithms With Uniform Crossover: The Hyperclimbing Hypothesis

description: The hyperclimbing hypothesis is a hypothetical explanation for adaptation in genetic algorithms with uniform crossover (UGAs). Hyperclimbing is an intuitive, general-purpose, non-local search heuristic applicable to discrete product spaces with rugged or stochastic cost functions. The strength of this heuristic lie in its insusceptibility to local optima when the cost function is deterministic, and its tolerance for noise when the cost function is stochastic. Hyperclimbing works by decimating a search space, i.e. by iteratively fixing the values of small numbers of variables. The hyperclimbing hypothesis holds that UGAs work by implementing efficient hyperclimbing. Proof of concept for this hypothesis comes from the use of a novel analytic technique involving the exploitation of algorithmic symmetry. We have also obtained experimental results that show that a simple tweak inspired by the hyperclimbing hypothesis dramatically improves the performance of a UGA on large, random instances of MAX-3SAT and the Sherrington Kirkpatrick Spin Glasses problem.

description: Let $C$ be a convex subset of a locally convex space. We provide optimal approximate fixed point results for sequentially continuous maps $f\colon C\to\bar{C}$. First we prove that if $f(C)$ is totally bounded, then it has an approximate fixed point net. Next, it is shown that if $C$ is bounded but not totally bounded, then there is a uniformly continuous map $f\colon C\to C$ without approximate fixed point nets. We also exhibit an example of a sequentially continuous map defined on a compact convex set with no approximate fixed point sequence. In contrast, it is observed that every affine (not-necessarily continuous) self-mapping a bounded convex subset of a topological vector space has an approximate fixed point sequence. Moreover, it is constructed a affine sequentially continuous map from a compact convex set into itself without fixed points.

Recovery of multi-antibiotic resistant Enterobacterales from retail fresh vegetables and the potential transfer of plasmid-mediated colistin resistance gene, mcr-1, in sprouts
Creators: name: Luo, Xin
Publisher: name: No Publisher Supplied
Year: 2022

description: Colistin is a last line therapeutic option in treatment of infections caused by extended spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae. Enterobacterales in fresh vegetables which are usually consumed raw could be reservoirs of multi-drug resistance bacteria. Moreover, the emergence of mobile colistin resistant gene, mcr-1, in Enterobacterales has become a global public health problem. Therefore, this research is to screen the presence of colistin and β-lactam resistance as well as associated genes from retailed fresh vegetables. The factors of effecting transfer frequency of mcr-1 gene in pathogenic Escherichia coli were also evaluated in broth media and food.Colistin resistant bacteria in lettuce and seed sprouts were detected by selective media, and their antibiotic susceptibility profile were determined. A mcr-1 positive bacteria (E. coli NCTC 13846) served as donor and two recipients (E. coli O157:H7 and E. coli O104:H4) were used for conjugative experiments in TSB media at 4, 25 and 37°C for up to 36 hours, as well as in germination process of seed sprouts.The aerobic plate count for lettuce and seed sprouts ranged from 3.88 to 8.47 log CFU/g and the population of bacteria capable of growth on MAC agar supplemented with colistin ranged from 1.55 to 5.76 log CFU/g. Isolates from MAC agar were identified as Serratia marcescens, Providencia, Morganella morganii, Enterobacter spp., Pseudomonas putida, Escherichia coli and Stenotrophomonas maltophilia. Extensively drug resistant bacteria were recovered, 8% of isolates were resistant to >5 antibiotics. The colistin resistance genes, mcr-1 to mcr-4, were not detected, however, blaSHV, blaTEM,and blaCTX-M group genes that encode for beta-lactamase were detected in several colistin tolerant bacteria. The transfer frequency was 10-7 to 10-8 per recipient cell for both two pathogenic E. coli at 25°C and 37°C. No transconjugants were detected at 4°C. However, higher transfer frequency (10⁻³ to 10⁻⁵ per recipient) of mcr-1 was occurred during mung bean sprouts germination. E. coli O104:H4 showed a better conjugative capability on mung bean sprouts than E. coli O157:H7. Susceptibility of several transconjugants to colistin was increased compared with donor cells.The spread of extensively antibiotic resistant bacteria through the global food supply from non-food animal derived products (fresh produce) is a potential human health concern. The horizontal gene transfer in liquid media could be underestimated which cannot represent a real situation. Food matrix is an important habitat for exchanging of the antibiotic resistant gene (ARGs) between microorganisms, potentially facilitating the spread of antibiotic resistance to human.
Spin current induced magnetization oscillations in a paramagnetic disc

description: When electron spins are injected uniformly into a paramagnetic disc, they can precess along the demagnetizing field induced by the resulting magnetic moment. Normally this precession damps out by virtue of the spin relaxation which is present in paramagnetic materials. We propose a new mechanism to excite a steady-state form of this dynamics by injecting a constant spin current into this paramagnetic disc. We show that the rotating magnetic field generated by the eddy currents provide a torque which makes this possible. Unlike the ferromagnetic equivalent, the spin-torque-oscillator, the oscillation frequency is fixed and determined by the dimensions and intrinsic parameters of the paramagnet. The system possesses an intrinsic threshold for spin injection which needs to be overcome before steady-state precession is possible. The additional application of a magnetic field lowers this threshold. We discuss the feasibility of this effect in modern materials. Transient analysis using pump-probe techniques should give insight in the physical processes which accompany this effect.
Within the reach of art: techniques of ineffability in eighteenth-century aesthetics
Creators: name: Martin, Kirsten
Publisher: name: No Publisher Supplied
Year: 2022

description: “Within the Reach of Art” argues that eighteenth-century writers and artists located the origins of so-called “effortless” aesthetic effects in a set of replicable techniques. While many writings of the period were enamored with the idea of such an effect—what Alexander Pope famously called a “a grace beyond the reach of art”—they were often content to dismiss it as inexplicable. And critics, who have been eager to equate the rise of the aesthetic with the emergence of subjective taste, have tended to dismiss technique as irrelevant and even at odds with aesthetic appreciation. Yet, by putting literary criticism into dialogue with the fields of art history and intellectual history, I examine how an array of figures from Jonathan Richardson to Laurence Sterne, sought to trace effects like “grace” back to the practices that produced them. Even if they were still unable to describe such effects in words, these writers could at least explain how to practically achieve them. A turn to technique, I show, unsettles the popular narrative that eighteenth-century aesthetic experience depended on the bracketing of explanations, and reveals the practical dimension that undergirded so many of the period’s meditations on art. Indeed, works by Richardson and Sterne, which are littered with commentaries on painterly and literary techniques, often take the form of “how-to” manuals. But such texts also struggle to put their suggested practices into words. They strive to develop a vocabulary that can bridge the gap between the subjective experience of beholding art and the embodied one of making it. Practical writings—which I define capaciously as anything from a treatise on painting to a novel that meditates on its own techniques—suggest how works of art might be understood as made objects, for beholders as well as practitioners. In four chapters about practitioner-writers—Jonathan Richardson and Alexander Cozens, among other minor figures; William Hogarth; Adam Smith and Laurence Sterne; Joshua Reynolds—I uncover a different technique or set of techniques for achieving elusive effects. Each of these techniques, whether it be throwing a sponge at a canvas or using an Old Master’s mind as a springboard for one’s own innovations, offers a practical means to achieve an elusive effect that does not appear to be the result of mimesis or mere mechanical reproduction. And what these practical explanations ultimately yield, I argue, is a new account of eighteenth-century intellectual history that posits aesthetic knowledge as transmissible and subject to change. Beholders learned to appreciate art because of not despite the fact that they could see it as a window into the artist’s technique.
Sign Changes of the Liouville function on quadratics

description: Let $λ(n)$ denote the Liouville function. Complementary to the prime number theorem, Chowla conjectured that \vspace{1mm} \noindent {\bf Conjecture (Chowla).} {\em \begin{equation} \label{a.1} \sum_{n\le x} λ(f(n)) =o(x) \end{equation} for any polynomial $f(x)$ with integer coefficients which is not of form $bg(x)^2$. } \vspace{1mm} \noindent The prime number theorem is equivalent to \eqref{a.1} when $f(x)=x$. Chowla's conjecture is proved for linear functions but for the degree greater than 1, the conjecture seems to be extremely hard and still remains wide open. One can consider a weaker form of Chowla's conjecture, namely, \vspace{1mm} \noindent {\bf Conjecture 1 (Cassaigne, et al).} {\em If $f(x) \in \Z [x]$ and is not in the form of $bg^2(x)$ for some $g(x)\in \Z[x]$, then $λ(f(n))$ changes sign infinitely often.} Clearly, Chowla's conjecture implies Conjecture 1. Although it is weaker, Conjecture 1 is still wide open for polynomials of degree $>1$. In this article, we study Conjecture 1 for the quadratic polynomials. One of our main theorems is {\bf Theorem 1.} {\em Let $f(x) = ax^2+bx +c $ with $a>0$ and $l$ be a positive integer such that $al$ is not a perfect square. Then if the equation $f(n)=lm^2 $ has one solution $(n_0,m_0) \in \Z^2$, then it has infinitely many positive solutions $(n,m) \in \N^2$.} As a direct consequence of Theorem 1, we prove some partial results of Conjecture 1 for quadratic polynomials are also proved by using Theorem 1.
HP-sequence design for lattice proteins - an exact enumeration study on diamond as well as square lattice

description: We present an exact enumeration algorithm for identifying the {\it native} configuration - a maximally compact self avoiding walk configuration that is also the minimum energy configuration for a given set of contact-energy schemes; the process is implicitly sequence-dependent. In particular, we show that the 25-step native configuration on a diamond lattice consists of two sheet-like structures and is the same for all the contact-energy schemes, ${(-1,0,0);(-7,-3,0); (-7,-3,-1); (-7,-3,1)}$; on a square lattice also, the 24-step native configuration is independent of the energy schemes considered. However, the designing sequence for the diamond lattice walk depends on the energy schemes used whereas that for the square lattice walk does not. We have calculated the temperature-dependent specific heat for these designed sequences and the four energy schemes using the exact density of states. These data show that the energy scheme $(-7,-3,-1)$ is preferable to the other three for both diamond and square lattice because the associated sequences give rise to a sharp low-temperature peak. We have also presented data for shorter (23-, 21- and 17-step) walks on a diamond lattice to show that this algorithm helps identify a unique minimum energy configuration by suitably taking care of the ground-state degeneracy. Interestingly, all these shorter target configurations also show sheet-like secondary structures.

description: In this article we extend the currently established diffusion theory of spin-dependent electrical conduction by including spin-dependent thermoelectricity and thermal transport. Using this theory, we propose new experiments aimed at demonstrating novel effects such as the spin-Peltier effect, the reciprocal of the recently demonstrated thermally driven spin injection, as well as the magnetic heat valve. We use finite-element methods to model specific devices in literature to demonstrate our theory. Spin-orbit effects such as anomalous-Hall, -Nernst, anisotropic magnetoresistance and spin-Hall are also included in this model.

Users revisiting the same page would be able to fetch the required information much faster if the information that they consumed during the previous visit(s) gets presented to them with a special style. This paper proposes a model which empowers the users to mark the content interesting to them, so that it can be identified easily during successive visits. In addition to the explicit marking by the users, the model facilitates implicit marking based on the user preferences. The prototype implementation based on proposed model validates the model's efficiency.

One of these conditions involves jacobians, and the second - some properties of factors. In the case of m=n this extends the known theorem of Nousiainen, and we obtain a new formulation of the jacobian conjecture in positive characteristic.

Universal amplitude ratios for scaling corrections on Ising strips with fixed boundary conditions

Year: 2011
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We study the (analytic) finite-size corrections in the Ising model on the strip with fixed ($+ -$) boundary conditions. We find that subdominant finite-size corrections to scaling should be to the form $a_k/N^{2k-1}$ for the free energy $f_N$ and $b_k^{(n)}/N^{2k-1}$ for inverse correlation length $ξ_n^{-1}$, with integer value of $k$. We investigate the set $\{a_k, b_k^{(n)}\}$ by exact evaluation and their changes upon varying anisotropy of coupling. We find that the amplitude ratios $b_k^{(n)}/a_k$ remain constant upon varying coupling anisotropy. Such universal behavior are correctly reproduced by the conformal perturbative approach.

description: We study the distribution of equilibrium avalanches (shocks) in Ising spin glasses which occur at zero temperature upon small changes in the magnetic field. For the infinite-range Sherrington-Kirkpatrick model we present a detailed derivation of the density rho(Delta M) of the magnetization jumps Delta M. It is obtained by introducing a multi-component generalization of the Parisi-Duplantier equation, which allows us to compute all cumulants of the magnetization. We find that rho(Delta M) ~ (Delta M)^(-tau) with an avalanche exponent tau=1 for the SK model, originating from the marginal stability (criticality) of the model. It holds for jumps of size 1 << Delta M < N^(1/2) being provoked by changes of the external field by delta H = O(N^[-1/2]) where N is the total number of spins. Our general formula also suggests that the density of overlap q between initial and final state in an avalanche is rho(q) ~ 1/(1-q). These results show interesting similarities with numerical simulations for the out-of-equilibrium dynamics of the SK model. For finite-range models, using droplet arguments, we obtain the prediction tau= (d_f + theta)/d_m, where d_f,d_m and theta are the fractal dimension, magnetization exponent and energy exponent of a droplet, respectively. This formula is expected to apply to other glassy disordered systems, such as the random-field model and pinned interfaces. We make suggestions for further numerical investigations, as well as experimental studies of the Barkhausen noise in spin glasses.

description: Metallocenes can be encapsulated inside the carbon nanotubes. The structural, energetic and electronic properties of organometallic MCp2@SWCNT are obtained from DFT method. We verify that such encapsulation is noncovalent functionalization, and examined binding energies and charge transfers of MCp2@(16,0)SWCNT systems. Consistent with recent experimental findings, the optimal distance between FeCp2 center and near tube-wall is 4.7 (5.1) Å for the configuration where MCp2's five-fold axis is parallel (vertical) to nanotube axis, while the minimal diameter is 9.4 (10.2) Å to exothermically encapsulate FeCp2 molecules. Finally we clarify the doping effects near the bandgap by encapsulations of CoCp2 and NiCp2.

description: Surveys have revealed a class of object displaying both high X-ray luminosities (Lx > 10^42 erg/s), and a lack of a discernible active galactic nucleus (AGN) in the optical band. If these sources are powered by star formation activity alone, they would be the most extreme X-ray luminosity star forming galaxies known. We have investigated the mechanism driving the X-ray luminosities of such galaxies by studying the X-ray emission of three moderate redshift (z ~ 0.1) examples of this class, selected from a cross-correlation of the SDSS-DR5 and 2XMMp-DR0 catalogues. X-ray spatial and long-term variability diagnostics of these sources suggest that they are compact X-ray emitters. This result is supported by the detection of rapid short term variability in an observation of one of the sources. The X-ray spectra of all three sources are best fitted with a simple absorbed power-law model, thus betraying no significant signs of star formation. These results indicate that the X-ray emission is powered by AGN activity. But why do these sources not display optical AGN signatures? We show that the most likely explanation is that the optical AGN emission lines are being diluted by star formation signatures from within their host galaxies.

We construct the relativistic Landau levels by solving corresponding Dirac equation in (2+1) dimensional noncommutative phase space. We observe that lowest Landau levels are exactly same as in commutative space and independent of non-commutative parameter. All the Landau levels become independent of noncommutative parameter for a critical value of the magnetic field. Several other interesting features along with the relevance of such models in the study of atomic transitions in a radiation field have been discussed.

Discreet and limited number of groups are defined in the distribution function, where each group is represented only with one value instead of a range of value. The produced sequences are also checked back whether they still fit the discreet distribution function. Increasing of number of particles N increases the value of correlation coefficient R^2, but increasing number of groups M reduces it. Value R^2 = 1 can be found for N = 1000000 at least with M = 5000$ and for M = 10 at least with N = 1000.

description: Questo contributo propone un itinerario di riflessione attraverso i testi spinoziani, per discutere il rapporto tra politica e immaginazione. Questo rapporto produce, infatti, forme di rappresentazione e di auto-rappresentazione che ricadono sulla forma e sull’organizzazione politica di una comunità. A partire dalla natura dell’immaginazione, per come viene descritta nell’Etica di Spinoza, e attraverso l’esposizione dell’esempio ebraico, Spinoza mostra una particolare idea della politica e della storia che apre a una critica dell’ideologia e collega la rappresentazione umana della realtà con le possibilità di dominio della necessità naturale, spazi che possono essere ampliati attraverso un equilibrio fra comunità umana e natura.

description: Similar to other countries, Departments of Family Medicine in the former Yugoslavia had to transition from face-to-face to distance education during COVID-19. To elucidate obstacles and facilitators of the transition from face-to-face to distance education. A cross-sectional, multicentre, qualitative study design was used to analyse nine open-ended questions from an online survey using inductive thematic analysis. The questionnaire was distributed to 21 medical schools, inviting them to involve at least two teachers/students/trainees. Data were collected between December 2021 and March 2022. In 17 medical schools, 23 students, 54 trainees and 40 teachers participated. The following themes were identified: facilitators and barriers of transition, innovations for enhancing distance education, convenience of distance education, classical teaching for better communication, the future of distance education, reaching learning outcomes and experience of online assessment. Innovations referred mainly to new online technologies for interactive education and communication. Distance education allowed for greater flexibility in scheduling and self-directed learning; however, participants felt that classical education allowed better communication and practical learning. Teachers believed knowledge-related learning outcomes could be achieved through distance education but not teaching clinical skills. Participants anticipated a future where a combination of teaching methods is used. The transition to distance education was made possible thanks to its flexible scheduling, innovative tools and possibility of self-directed learning. However, face-to-face education was considered preferable for fostering interpersonal relations and teaching clinical skills. Educators should strive to strike a balance between innovative approaches and the preservation of personal experiences. Participants found that distance education offers many possibilities, mainly self-directed, flexible learning. Participants felt that face-to-face education remains invaluable since it facilitates communication and the development of practical skills. A balance between new technologies and personal encounters was believed to be best.

description: We calculate the contribution of the higher twist Feynman diagrams to the large-$p_T$ inclusive pion production cross section in proton-proton collisions in the case of the running and frozen coupling approaches within holographic QCD. The structure of infrared renormalon singularities of the higher twist subprocess cross section and it's resummed expression are found. We compare the resummed higher twist cross sections with the ones obtained in the framework of the frozen coupling approximation and leading twist cross section. We discuss the phenomenological consequences of possible higher-twist contributions to the pion production in proton-proton collisions within holographic QCD.

Complessità, agency ed emergenza del significato nei sistemi viventi. Un approccio teleologico
Creators: name: Di Bernardo, Mirko

Year: 2016
Subjects: Filosofia della biologia, vita, cognizione, intenzionalità, precondizioni dell'etica

description: Mantenendo come orizzonte di riferimento la teoria dell’agency di S.A. Kauffman e la neurobiologia del significato di W.J. Freeman, l’articolo, mediante il ricorso ad uno specifico approccio epistemologico legato alla teoria della complessità biologica, prende in esame la possibilità di interpretare la vita e la cognizione come fenomeni emergenti alla stregua di livelli gerarchici di auto-organizzazione in costante coevoluzione. In quest’ottica, i recentissimi risultati relativi a tale inedita frontiera, strettamente connessa con l’emergenza di una vera e propria rivoluzione concettuale a livello dell’analisi di quel particolare entaglement di significato, auto-organizzazione biologica, intenzionalità e teleologia, mostrano la necessità di elaborare un nuovo approccio naturalistico non riduzionista al problema relativo alle precondizioni della capacità morale in grado di tener conto, mantenendo ben distinti i piani di riferimento, non solo del dispiegarsi proprio delle forme naturali della cognizione umana, ma anche della genesi delle strutture intenzionali (non riferite alla coscienza) in agenti autonomi non umani, intesi come attori costruttori capaci di creare sempre nuovi significati attraverso la realizzazione di azioni imprevedibili (know-how). Ci si riferisce qui, in accordo con Kauffman, all'idea secondo cui rudimenti di semantica, di intenzionalità, di valore e di etica nascano con gli agenti autonomi e quindi siano intrinsecamente correlati alla nozione stessa di vita.

La pedagogia di Richard Rorty: dare vita e senso alla filosofia

description: Se la pedagogia può essere a tutti gli effetti paragonata ad una fenice, anche la filosofia rortyana può esserlo. Come la pedagogia ha la capacità di rinascere dalle proprie ceneri, rigenerarsi con un’energia e una luce nuova, così Richard Rorty è in grado di far rinascere la filosofia, darle nuova vita, un senso, uno scopo. Il pragmatismo ha indubbiamente contribuito a questo risultato. La filosofia diventa preziosa, utile, viva e indispensabile proprio nel momento in cui dalla mera teoresi passa alla pratica. I pragmatisti si interessano di tutti quei problemi che possono avere una finalità e utilità pratica. Rorty, allo stesso modo, dà una nuova spinta e un nuovo impulso alla filosofia che risorge dalle proprie ceneri proprio come una fenice.

Relativistic theory of the double photoionization of helium-like atoms

Publisher: name: arXiv
Year: 2011
Subjects: subject: Atomic Physics (physics.atom-ph)

description: A fully relativistic calculation of the double photoionization of helium-like atoms is presented. The approach is based on the partial-wave representation of the Dirac continuum states and accounts for the retardation in the electron-electron interaction as well as the higher-order multipoles of the absorbed photon. The electron-electron interaction is taken into account to the leading order of perturbation theory. The relativistic effects are shown to become prominent already for the medium-Z ions, changing the shape and the asymptotic behaviour of the photon energy dependence of the ratio of the double-to-single photoionization cross section.

description: Le concezioni dello sviluppo mentale sviluppate da due grandi personaggi della psicologia: Piaget e Vygotskij in quanto queste risultano essere le più importanti del nostro secolo. I motivi di tale significatività sono almeno due: l'ampiezza e la consistenza di cui ciascuna concezione da un punto di vista teorico, raggiunte mediante l'approccio interdisciplinare ai problemi adottato da entrambi gli autori; la grande risonanza che ognuna di esse ha suscitato e suscita non solo nell'ambito degli studi sullo sviluppo mentale, ma anche in quelli sulla cognizione e sull'educazione in generale.

description: Point Spread Function (PSF) modeling is a central part of any astronomy data analysis relying on measuring the shapes of objects. It is especially crucial for weak gravitational lensing, in order to beat down systematics and allow one to reach the full potential of weak lensing in measuring dark energy. A PSF modeling pipeline is made of two main steps: the first one is to assess its shape on stars, and the second is to interpolate it at any desired position (usually galaxies). We focus on the second part, and compare different interpolation schemes, including polynomial interpolation, radial basis functions, Delaunay triangulation and Kriging. For that purpose, we develop simulations of PSF fields, in which stars are built from a set of basis functions defined from a Principal Components Analysis of a real ground-based image. We find that Kriging gives the most reliable interpolation, significantly better than the traditionally used polynomial interpolation. We also note that although a Kriging interpolation on individual images is enough to control systematics at the level necessary for current weak lensing surveys, more elaborate techniques will have to be developed to reach future ambitious surveys' requirements.

description: A model function relating effective stress to fracture permeability is developed from Hooke's law, implemented in the tensorial form of Darcy's law, and used to evaluate discharge rates and pressure distributions at regional scales. The model takes into account elastic and statistical fracture parameters, and is able to simulate real stress-dependent permeabilities from laboratory to field studies. This modeling approach gains in phenomenology in comparison to the classical ones because the permeability tensors may vary in both strength and principal directions according to effective stresses. Moreover this method allows evaluation of the fracture porosity changes, which are then translated into consolidation of the medium.

YSO jets in the Galactic Plane from UWISH2: I - MHO catalogue for Serpens and Aquila

description: Jets and outflows from Young Stellar Objects (YSOs) are important signposts of currently ongoing star formation. In order to study these objects we are conducting an unbiased survey along the Galactic Plane in the 1-0S(1) emission line of molecular hydrogen at 2.122mu using the UK Infrared Telescope. In this paper we are focusing on a 33 square degree sized region in Serpens and Aquila (18deg < l < 30deg; -1.5deg < b < +1.5deg). We trace 131 jets and outflows from YSOs, which results in a 15 fold increase in the total number of known Molecular Hydrogen Outflows. Compared to this, the total integrated 1-0S(1) flux of all objects just about doubles, since the known objects occupy the bright end of the flux distribution. Our completeness limit is 3*10^-18Wm^-2 with 70% of the objects having fluxes of less than 10^-17Wm^-2. Generally, the flows are associated with Giant Molecular Cloud complexes and have a scale height of 25-30pc with respect to the Galactic Plane. We are able to assign potential source candidates to about half the objects. Typically, the flows are clustered in groups of 3-5 objects, within a radius of 5pc. These groups are separated on average by about half a degree, and 2/3rd of the entire survey area is devoid of outflows. We find a large range of apparent outflow lengths from 4arcsec to 130arcsec. If we assume a distance of 3kpc, only 10% of all outflows are of parsec scale. There is a 2.6sigma over abundance of flow position angles roughly perpendicular to the Galactic Plane.
