description: The Enskog-like kinetic approach, recently introduced by us to study strongly inhomogeneous flu- ids, is reconsidered in order to improve the description of the transport coefficients. The approach is based on a separation of the interaction between hydrodynamic and non-hydrodynamic parts. The latter is treated within a simple relaxation approximation. We show that, by considering the non-hydrodynamic part via a weighted density approximation, we obtain a better prediction of the transport coefficients. By virtue of the simplicity of the kinetic equation we are able to solve numer- ically the phase space distribution in the presence of inhomogeneities, such as confining surfaces, via a Lattice Boltzmann method. Analytical estimates of the importance of these corrections to the transport coefficients in bulk conditions is provided. Poiseuille flow of the hard-sphere fluid confined between two parallel smooth walls is studied and their pore-averaged properties are determined.

description: The discovery of quasi-periodic oscillations (QPOs) in magnetar giant flares has opened up prospects for neutron star asteroseismology. However, with only three giant flares ever recorded, and only two with data of sufficient quality to search for QPOs, such analysis is seriously data limited. We set out a procedure for doing QPO searches in the far more numerous, short, less energetic magnetar bursts. The short, transient nature of these bursts requires the implementation of sophisticated statistical techniques to make reliable inferences. Using Bayesian statistics, we model the periodogram as a combination of red noise at low frequencies and white noise at high frequencies, which we show is a conservative approach to the problem. We use empirical models to make inferences about the potential signature of periodic and quasi-periodic oscillations at these frequencies. We compare our method with previously used techniques and find that although it is on the whole more conservative, it is also more reliable in ruling out false positives. We illustrate our Bayesian method by applying it to a sample of 27 bursts from the magnetar SGR J0501+4516 observed by the Fermi Gamma-ray Burst Monitor, and we find no evidence for the presence of QPOs in any of the bursts in the unbinned spectra, but do find a candidate detection in the binned spectra of one burst. However, whether this signal is due to a genuine quasi-periodic process, or can be attributed to unmodeled effects in the noise is at this point a matter of interpretation.

Gaps in Protoplanetary Disks as Signatures of Planets: II. Inclined Disks

description: We examine the observational appearance of partial gaps being opened by planets in protoplanetary disks, considering the effects of the inclination relative to the line of sight. The gap's trough is darkened by both shadowing and cooling, relative to the uninterrupted disk. The gap's outer wall is brightened by direct illumination and also by heating, which puffs it up so that it intercepts more starlight. In this paper, we examine the effects of inclination on resolved images of disks with and without gaps at a wide range of wavelengths. The scattering surface's offset from the disk midplane creates a brightness asymmetry along the axis of inclination, making the disk's near side appear brighter than the far side in scattered light. Finite disk thickness also causes the projected distances of equidistant points on the disk surface to be smaller on the near side of the disk as compared to the far side. Consequently, the gap shoulder on the near side of the disk should appear brighter and closer to the star than on the far side. However, if the angular resolution of the observation is coarser than the width of the brightened gap shoulder, then the gap shoulder on the far side may appear brighter because of its larger apparent size. We present a formula to recover the scale height and inclination angle of an imaged disk using simple geometric arguments and measuring disk asymmetries. Resolved images of circumstellar disks have revealed clearings and gaps, such as the transitional disk in LkCa 15. Models created using our synthetic imaging attempting to match the morphology of observed scattered light images of LkCa 15 indicate that the H-band flux deficit in the inner $\sim0.5\arcsec$ of the disk can be explained with a planet of mass greater than 0.5 Jupiter mass.

description: Edictum Theoderici heißt in der Forschung eine Sammlung von 154 Rechtssätzen, die von einem Prolog und einem Epilog gerahmt werden; diese bezeichnen sowohl die Sammlung als ganze als auch die einzelnen Rechtssätze als Edikt. Urheberschaft, Entstehung und Zweck der Sammlung sind seit langem umstritten; ein Konsens zeichnet sich nicht ab. Die Frage, weshalb der Text sich selbst als Edikt bezeichnet, wurde bislang noch gar nicht gestellt. Der Aufsatz verteidigt zunächst die Zuschreibung an den ostgotischen König Theoderich und entwickelt auf dieser Grundlage die These, daß die Rechtssammlung zwar zur Anwendung vor Gericht bestimmt war, aber zunächst und vor allem eine symbolische Botschaft vermitteln sollte. Diese symbolische Botschaft erschöpfte sich nicht darin, Theoderich als rastlos tätigen und fürsorglichen Herrscher zu zeigen. Vielmehr verwies das Edictum Theoderici durch seine formale Gestalt bewußt auf das Prätorische Edikt, das in der Spätantike in der Form des Edictum perpetuum bekannt war und als Inbegriff magistratischer Jurisdiktion galt. Indem der König eine Rechtssammlung veröffentlichte, deren Form dem Prätorischen Edikt nachgebildet war – wahrscheinlich im Rahmen seines Rom-Besuchs im Jahre 500 –, stilisierte er sich zum römischen Magistraten, wenngleich nicht zum Inhaber eines bestimmten Amtes. Der von Theoderich geprägte, ‹magistratische Stil› der ostgotischen Gesetzgebung war Ausdruck und Mittel einer Politik, die auf die Kooperation mit den zivilen Eliten Italiens abzielte und die Anerkennung des Kaisers erstrebte. Er wurde auch von der Regierung seines Enkels und Nachfolgers Athalarichs gepflegt, verschwand jedoch im römisch-gotischen Krieg, als die Koalition zwischen gotischen Königen und weströmischem Senatorenstand zerbrach. Ein abschließender Vergleich mit den Rechtssammlungen, die etwa zur selben Zeit in den Herrschaftsgebieten westgotischer und burgundischer Könige herauskamen, unterstreicht den einzigartigen Charakter des Edictum Theoderici.

description: RNA interference (RNAi) is an important tool for gene function studies in insects, especially in non-model insects. This technology is also being developed for pest control. However, variable RNAi efficiency among insects is limiting its use in insects. Systemic RNAi in Caenorhabditis elegans requires systemic RNA interference defective protein 1 (CeSid1). The expression of CeSid1 in insect cell lines was shown to improve RNAi. However, the mechanisms through which this double-stranded RNA (dsRNA) transporter improves RNAi efficiency in insects is not known. We stably expressed CeSid1 in two Spodoptera frugiperda cell lines, Sf9 and Sf17 cells derived from ovary and midgut, respectively. Expression of CeSid1 enhanced RNAi efficiency in ovarian Sf9 cells, but not in midgut Sf17 cells. Reduced accumulation of dsRNA in late endosomes and successful processing dsRNA to siRNA contribute to enhanced RNAi efficiency in Sf9 cells. Transgenic S. frugiperda expressing CeSid1 were produced and tested for RNAi efficiency. RNAi efficiency enhancement due to CeSid1 expression showed tissue specificity. Compared to RNAi efficiency in wild-type S. frugiperda, CeSid1 expressing transgenic S. frugiperda showed a significant improvement of RNAi in tissues such as Verson’s glands. In contrast, no improvement in RNAi was observed in tissues such as midgut. The in vitro cell-type specific and in vivo tissue-specific enhancement of RNAi efficiency by CeSid1 in S. frugiperda provides valuable information for improving RNAi in insects such as those belonging to order Lepidoptera where RNAi is variable and inefficient.

Die hier publizierte und besprochene Dokumentation vermag nur Einzelaspekte sichtbar zu machen. Das gilt von der in einer stark zerstörten Inschrift mit vielen Details über Abläufe im Heiligtum thematisierten hellenistischen Neokorie ebenso wie von dem agonistischen Stadtfest zu Ehren des Gottes, das sich mit sechs gleichartigen Siegermonumenten von Commodus bis Valerian verfolgen läßt, aber von seiner ‹Aussage› kaum etwas preisgibt. In Anhängen werden vier Votivaltäre für einen rätselhaften, Zeus vielleicht nahestehenden ‹Lykischen Gott› und seine ‹Kinder›, ein Hausaltar für den Augustus-Kult und eine als Meilenstein konzipierte Ehrensäule für Commodus präsentiert.

Der Name des Kaisers steht aber auf Rasur, was bisher nicht erkannt worden ist. Ursprünglich muss daher ein anderer Kaiser als Bauherr genannt worden sein; aufgrund der historischen Situation in Lykien im Vier-Kaiser-Jahr unter dem Statthalter Sex. Marcius Priscus und der Raumverhältnisse der Inschrift ist Galba am wahrscheinlichsten. Die Inschrift lässt sich damit in einen größeren Kontext der epigraphischen Zeugnisse der unter Galba begonnenen Wiederaufbauarbeiten nach Erdbebenschäden in Lykien einordnen. Diskutiert wird auch das im Zuge von Eradierung und Überschreibung neu entstandene, ungewöhnliche Epitheton ἐπιφανὴς γῆς καὶ θαλάσσης für Vespasian.

description: A film editor, director, writer, and archivist, Elizaveta Svilova was an intellectual and creative force in early Soviet montage. She is best known for her extensive collaborations with her husband, Dziga Vertov, on seminal early documentary films, and especially for instances when she appeared on camera demonstrating the act of editing itself. The fact that Vertov’s filmic theory and practice focused on montage as the fundamental guiding force of cinema confirms the crucial role Svilova’s groundbreaking experimentation played in early Soviet film and global film history. Her career, which spanned far beyond her collaborations with her husband, significantly advanced the early principles of cinematic montage.

description: Here we investigate LaAlO_3-SrTiO_3 heterostructure withδ-doping of the interface by LaMnO_3 at less than one monolayer. This doping strongly inhibits the formation of mobile electron layer at the interface. This results in giant increase of the resistance and the thermopower of the heterostructure. Several aspects of this phenomena are investigated. A model to calculate the carrier concentration is presented and effect of doping and detailed temperature dependence is analyzed in terms of model parameters and the weak-scattering theory. The large enhancement of thermopower is attributed to the increased spin and orbital entropy originating from the LaMnO_3 mono-layer.
AdS flowing black funnels: Stationary AdS black holes with non-Killing horizons and heat transport in the dual CFT

description: We construct stationary non-equilibrium black funnels locally asymptotic to global AdS4 in vacuum Einstein-Hilbert gravity with negative cosmological constant. These are non-compactly-generated black holes in which a single connected bulk horizon extends to meet the conformal boundary. Thus the induced (conformal) boundary metric has smooth horizons as well. In our examples, the boundary spacetime contains a pair of black holes connected through the bulk by a tubular bulk horizon. Taking one boundary black hole to be hotter than the other ($ΔT \neq 0$) prohibits equilibrium. The result is a so-called flowing funnel, a stationary bulk black hole with a non-Killing horizon that may be said to transport heat toward the cooler boundary black hole. While generators of the bulk future horizon evolve toward zero expansion in the far future, they begin at finite affine parameter with infinite expansion on a singular past horizon characterized by power-law divergences with universal exponents. We explore both the horizon generators and the boundary stress tensor in detail. While most of our results are numerical, a semi-analytic fluid/gravity description can be obtained by passing to a one-parameter generalization of the above boundary conditions. The new parameter detunes the temperatures $T_{bulk BH}$ and $T_{bndy BH}$ of the bulk and boundary black holes, and we may then take α= $T_\mathrm{bndy BH}/T_\mathrm{bulk BH}$ and ΔT small to control the accuracy of the fluid-gravity approximation. In the small α, ΔT regime we find excellent agreement with our numerical solutions. For our cases the agreement also remains quite good even for $α\sim 0.8$. In terms of a dual CFT, our α= 1 solutions describe heat transport via a large N version of Hawking radiation through a deconfined plasma that couples efficiently to both boundary black holes.

description: Silent films in Ireland from 1914 to 1935 focused on Irish rural life, the long struggle for independence from Great Britain, and the civil war that raged from 1922-1923 over the formation of the Irish Free State. Films like those from producers Ellen O’Mara and James Mark Sullivan’s indigenous Film Company of Ireland (1916-1920) specialized in romantic comedies/dramas of Irish life and historical melodramas on the Protestant Ascendency and its exploitation of Irish Catholic tenants. Screenwriter Mary Manning’s Guests of the Nation (1935) explored the Anglo/Irish War (1919-1921) and its devastating impact on the Irish countryside and its people. English-Irish author Dorothea Donn-Byrne worked in and outside this nationalist tradition. As Dolly Byrne, she provided the source material for Enter Madame (US 1922), a drawing room comedy about a self-absorbed opera singer and her troubled marriage, and, as Dorothea Donn Byrne, she wrote the original story for Land of Her Fathers (IE/US 1925), a romantic drama set against the backdrop of the Anglo/Irish War. In her prolific career, Donn-Byrne wrote for the stage and screen, and penned essays and short stories on a variety of topics that reflected the political and popular culture of the Anglo/Irish/American societies in which she lived. Her work in cinema points to the early dependence on source authors and story writers—particularly women—the nature of their contribution as cinematic authors, and the uncertainty surrounding their involvement in production.

description: RNAs are highly regulated at the post-transcriptional level in neurodegenerative diseases and just a few mutations can significantly affect the fate of neuronal cells. To date, the impact of G-quadruplex (G4) regulation in neurodegenerative diseases like Parkinson’s disease (PD) has not been analysed. In this study, in silico potential G4s located in deregulated genes related to the nervous system were initially identified and were found to be significantly enriched. Several G4 sequences found in the 5ʹ untranslated regions (5ʹUTR) of mRNAs associated with Parkinson’s disease were demonstrated to in fact fold in vitro by biochemical assays. Subcloning of the full-length 5ʹUTRs of these candidates upstream of a luciferase reporter system led to the demonstration that the G4s of both Parkin RBR E3 Ubiquitin Protein Ligase (PRKN) and Vacuolar Protein Sorting-Associated Protein 35 (VPS35) significantly repressed the translation of both genes in SH-SY5Y cells. Subsequently, a strategy of using label-free RNA affinity purification assays with either of these two G4 sequences as bait isolated the Guanine Nucleotide-Binding Protein-Like 1 (GNL1). The latter was shown to have a higher affinity for the G4 sequences than for their mutated version. This study sheds light on new RNA G-quadruplexes located in genes dysregulated in Parkinson disease and a new G4-binding protein, GNL1.

description: Angular distributions for elastic and inelastic scattering of $^3$He from $^{12}$C were measured at energies 50.5 and 60 MeV. The Airy minimum of the prerainbow scattering was clearly observed in the angular distributions for the 0$_2^+$ (7.65 MeV) state of $^{12}$C (Hoyle state). The experimental results were analyzed with a coupled channels method with double folding potentials derived from the microscopic wave functions for the ground 0$_1^+$, 2$^+$ (4.44 MeV), 3$^-$ (9.64 MeV) and 0$_2^+$ states. The analysis supports the view that the Hoyle state is a three alpha particle condensate with a large radius of dilute matter distribution.

Obwohl diese Landstücke in der Regel der Melioration bedurften, bevor sie bebaut werden konnten, kam es im 2. Jh. v. Chr. vermehrt vor, dass manche Soldaten normwidrig Kleroi bekamen, die aus ςπόριμος γῆ bestanden, d.h. aus Land, das unmittelbar bestellt werden konnte und für die Verpachtung an die sogenannten königlichen Bauern gedacht war. Bei der Besprechung und Revision der Quellen sind zwei Grundhaltungen der ptolemäischen Verwaltung festzustellen: Die Neigung, Ad-hoc-Entscheidungen rigiden und schriftlich fixierten Gegenmaßnahmen vorzuziehen, und die Tendenz, den Soldaten (vor allem den Katökenreitern) das Recht einzuräumen, die illegalen Kleroi zu behalten, wenn sie Gesuche an den König einreichten. Es wird vorgeschlagen, dies nicht unbedingt als Schwäche zu betrachten, sondern als Zeichen einer pragmatischen Haltung. Zum Schluss werden in Appendices zwei für diese Fragestellung wichtige, aber an verschiedenen Stellen problematische Texte, P.Meyer 1 und P.Tebt. I 124, revidiert und besprochen.

description: The past decade has seen an increasing number of investigations into enhanced diffusion of catalytically active enzymes [1]. These studies suggested that enzymes are actively propelled as they catalyze reactions or bind with ligands (e.g., substrates or inhibitors). In this Outlook, we chronologically summarize and discuss the experimental observations and theoretical interpretations and emphasize the potential contradictions in these efforts. We point out that the existing multimeric forms of enzymes or isozymes may cause artifacts in measurements and that the conformational changes upon substrate binding are usually not sufficient to give rise to a diffusion enhancement greater than 30%. Therefore, more rigorous experiments and a more comprehensive theory are urgently needed to quantitatively validate and describe the enhanced enzyme diffusion. We utilized dynamic light scattering (DLS) to measure the diffusion coefficient of aldolase in the absence and presence of its substrate [2]. The DLS measurements have an experimental error of 3% and do not find a statistically significant change of the aldolase diffusion coefficient even at a saturating substrate concentration. This finding lends support to the contention that photophysical artifacts may have affected the prior FCS measurements and challenges the idea that enzymes can be self-propelled by their catalytic activity.

description: A spectroscopic follow up of Ultra-Compact Dwarf (UCD) candidates in the fossil group NGC 1132 is undertaken with the Gemini Multi Object Spectrograph (GMOS). These new Gemini spectra prove the presence of six UCDs in the fossil group NGC 1132 at a distance of D~100 Mpc and a recessional velocity of v_r = 6935 +/- 11 km/s. The brightest and largest member of the UCD population is an M32 analog with a size of 77.1 pc and a magnitude of M_V=-14.8 mag with the characteristics in between those of the brightest UCDs and compact elliptical galaxies. The ensemble of UCDs have an average radial velocity of = 6966 +/- 208 km/s and a velocity dispersion of sigma_v = 169 +/-18 km/s similar to the one of poor galaxy groups. This work shows that UCDs can be used as test particles to determine the dynamical properties of galaxy groups. The presence of UCDs in the fossil group environment is confirmed and thus the fact that UCDs can form across diverse evolutionary conditions.

description: Several independent lines of evidence suggest that the stellar initial mass function (IMF) in early-type galaxies becomes increasingly `bottom-heavy' with increasing galaxy mass and/or velocity dispersion, sigma. Here we consider evidence for IMF variation in a sample of relatively compact early-type galaxies drawn from the Sloan Digital Sky Survey. These galaxies are of sufficiently high stellar density that a dark halo likely makes a minor contribution to the total dynamical mass, Mdyn, within one effective radius. We fit our detailed stellar population synthesis models to the stacked absorption line spectra of these galaxies in bins of sigma and find evidence from IMF-sensitive spectral features for a bottom-heavy IMF at high sigma. We also apply simple `mass-follows-light' dynamical models to the same data and find that Mdyn is significantly higher than what would be expected if these galaxies were stellar dominated and had a universal Milky Way IMF. Adopting Mdyn M_* therefore implies that the IMF is `heavier' at high sigma. Most importantly, the quantitative amount of inferred IMF variation is very similar between the two techniques, agreeing to within 0.1 dex in mass. The agreement between two independent techniques, when applied to the same data, provides compelling evidence for systematic variation in the IMF as a function of early-type galaxy velocity dispersion. Any alternative explanations must reproduce both the results from dynamical and stellar population-based techniques.

description: Multi-nucleon transfer reaction between 136Xe beam and 198Pt target was performed using the VAMOS++ spectrometer at GANIL to study the structure of n-rich nuclei around N=126. Unambiguous charge state identification was obtained by combining two supervised machine learning methods, deep neural network (DNN) and positional correction using a gradient-boosting decision tree (GBDT). The new method reduced the complexity of the kinetic energy calibration and outperformed the conventional method, improving the charge state resolution by 8%

description: We have calculated the proton charge radius by assuming that the real proton radius is not unique and the radii are randomly distributed in a certain range. This is performed by averaging the elastic electron-proton differential cross section over the form factor cut-off. By using a dipole form factor and fitting the middle value of the cut-off to the low $Q^2$ Mainz data, we found the lowest $χ^2/N$ for a cut-off $Λ=0.8203\pm 0.0003$ GeV, which corresponds to a proton charge radius $r_E=0.8333\pm 0.0004$ fm. The result is compatible with the recent precision measurement of the Lamb shift in muonic hydrogen as well as recent calculations using more sophisticated techniques. Our result indicates that the relative variation of the form factor cut-off should be around 21.5%. Based on this result we have investigated effects of the nucleon radius variation on the symmetric nuclear matter (SNM) and the neutron star matter (NSM) by considering the excluded volume effect in our calculation. The mass-radius relation of neutron star is found to be sensitive to this variation. The nucleon effective mass in the SNM as well as the equation of state of both the SNM and the NSM exhibit a similar sensitivity.

description: В статье представлены результаты исследовательской работы относительно предрасположенности глав крестьянских (фермерских) хозяйств к сотрудничеству и кооперации как условию успешного развития сельскохозяйственных потребительских кооперативов в современной социально-экономической и институциональной среде. Обращено внимание на следующие аспекты: создание кооперативов происходит чаще всего по инициативе государства, в хозяйственную практику инкорпорируется традиционная модель аграрного кооператива, инструменты господдержки пока не демонстрируют ожидаемой эффективности их применения.
description: The article presents the results of the research regarding the inclination of heads of farming en-terprises for collaboration and cooperation as a condition for the successful development of agricultural consumer cooperatives in the current socio-economic and institutional environment. Attention is drawn to the following points: the creation of cooperatives occurs more often at the initiative of the State; the traditional model of an agricultural cooperative is incorporated into the economic practice; the tools of state support do not demonstrate the expected effectiveness of their application yet.
Measurement of R = \boldmath${\mathcal{B}(t \rightarrow Wb)/\mathcal{B}(t \rightarrow Wq)} $ in Top--quark--pair Decays using Lepton+jets Events and the Full CDF Run II Data set

description: We present a measurement of the ratio of the top-quark branching fractions $R=\mathcal{B}(t\rightarrow Wb)/\mathcal{B}(t\rightarrow Wq)$, where $q$ represents quarks of type $b$, $s$, or $d$, in the final state with a lepton and hadronic jets. The measurement uses $\sqrt{s}$ = 1.96 TeV proton--antiproton collision data from 8.7 fb$^{-1}$ of integrated luminosity collected with the Collider Detector at Fermilab during Run II of the Tevatron. We simultaneously measure $R=0.94 \pm 0.09$ (stat+syst), the $t\bar{t}$ production cross section $σ_{t \bar t} = 7.5 \pm 1.0$ (stat+syst) pb. The magnitude of the Cabibbo-Kobayashi-Maskawa matrix element, $|V_{tb}| = 0.97 \pm 0.05$ (stat+syst) is extracted assuming three generations of quarks, and a lower limit of $|V_{tb}|>0.89$ at 95% credibility level is set.

description: Threats to both creativity and freedom of expression are on the rise globally, with Africa as no exception. As a result, artists, journalists and human rights defenders are seeking out shelter or safer locations in order to escape harm. However, the support systems cur­rently in place predominantly relocate at­-risk African artists to Europe and North America, which poses an additional set of social, cultural and economic challenges. This brief summarises key findings and recom­mendations of a report that investigates the successes and challenges of devel­oping temporary shelter and relocation initiatives based in Africa.

Magnetically generated spin-orbit coupling for ultracold atoms

description: We present a new technique for producing two- and three-dimensional Rashba-type spin-orbit couplings for ultracold atoms without involving light. The method relies on a sequence of pulsed inhomogeneous magnetic fields imprinting suitable phase gradients on the atoms. For sufficiently short pulse durations, the time-averaged Hamiltonian well approximates the Rashba Hamiltonian. Higher order corrections to the energy spectrum are calculated exactly for spin-1/2 and perturbatively for higher spins. The pulse sequence does not modify the form of rotationally symmetric atom-atom interactions. Finally, we present a straightforward implementation of this pulse sequence on an atom chip.
Study of the mass and spin-parity of the Higgs boson candidate via its decays to Z boson pairs

description: A study is presented of the mass and spin-parity of the new boson recently observed at the LHC at a mass near 125 GeV. An integrated luminosity of 17.3 inverse femtobarns, collected by the CMS experiment in proton-proton collisions at center-of-mass energies of 7 and 8 TeV, is used. The measured mass in the ZZ channel, where both Z bosons decay to e or mu pairs, is 126.2 +/- 0.6 (stat.) +/- 0.2 (syst.) GeV. The angular distributions of the lepton pairs in this channel are sensitive to the spin-parity of the boson. Under the assumption of spin 0, the present data are consistent with the pure scalar hypothesis, while disfavoring the pure pseudoscalar hypothesis.

description: The HII region luminosity function (LF) is an important tool for deriving the birthrates and mass distribution of OB associations, and is an excellent tracer of the newly formed massive stars and associations. To date, extensive work (predominantly in Hα) has been done from the ground, which is hindered by dust extinction and the severe blending of adjacent (spatially or in projection) HII regions. Reliably measuring the properties of HII regions requires a linear resolution <40 pc, but analyses satisfying this requirement have been done only in a handful of galaxies, so far. As the first space-based work using a galaxy sample, we have selected 12 galaxies from our HST NICMOS Paα survey and studied the luminosity function and size distribution of HII regions both in individual galaxies and cumulatively, using a virtually extinction-free tracer of the ionizing photon rate. The high angular resolution and low sensitivity to diffuse emission of NICMOS also offer an advantage over ground-based imaging by enabling a higher degree of de-blending of the HII regions. We do not confirm the broken power-law LFs found in ground-based studies. Instead, we find that the LFs, both individual and co-added, follow a single power law dN(L)/dlnL ~ L^-1, consistent with the mass function of star clusters in nearby galaxies, and in agreement with the results of the existing analyses with HST data. The individual and co-added size distribution of HII regions are both roughly consistent with dN(D)/dlnD ~ D^-3, but the power-law scaling is probably contaminated by blended regions or complexes.

description: For a spatial characteristic, there exist commonly fat-tail frequency distributions of fragment-size and -mass of glass, areas enclosed by city roads, and pore size/volume in random packings. In order to give a new analytical approach for the distributions, we consider a simple model which constructs a fractal-like hierarchical network based on random divisions of rectangles. The stochastic process makes a Markov chain and corresponds to directional random walks with splitting into four particles. We derive a combinatorial analytical form and its continuous approximation for the distribution of rectangle areas, and numerically show a good fitting with the actual distribution in the averaging behavior of the divisions.

description: As additional perturbative degrees of freedom, it is known that magnetic fields of inflationary origin can source curvature perturbations on super-Hubble scales. By requiring the magnetic generated curvature to remain smaller than its inflationary adiabatic counterpart during inflation and reheating, we derive new constraints on the maximal field value today, the reheating energy scale and its equation of state parameter. These bounds end up being stronger by a few order of magnitude than those associated with a possible backreaction of the magnetic field onto the background. Our results are readily applicable to any slow-roll single field inflationary models and any magnetic field having its energy density scaling as a^gamma during inflation. As an illustrative example, massive inflation is found to remain compatible with a magnetic field today Bo = 5 x 10^(-15) G for some values of gamma only if a matter dominated reheating takes place at energies larger than 10^5 GeV. Conversely, assuming gamma=-1, massive inflation followed by a matter dominated reheating cannot explain large scale magnetic fields larger than 10^(-20) G today.
