Die Seeablagerungen vom Samerberg/Obb. und ihre Stellung im Jungpleistozän
Creators: name: Grüger, Eberhard
Publisher: name: Geozon Science Media
Year: 1979

description: Die Seeablagerungen vom Samerberg stammen nach dem geologischen und dem vegetationsgeschichtlichen Befund aus der Riß/Würm-Warmzeit und aus dem Frühwürm. In klimageschichtlicher Hinsicht besteht eine ausgezeichnete Übereinstimmung mit den Untersuchungsergebnissen von den ebenfalls sehr umfangreichen Profilen von Grande Pile, Rederstall, Odderade und Kittlitz, in denen über dem Eem eine durch einen Klimarückschlag zweigeteilte ältere und eine ungegliederte jüngere Waldzeit, die Frühwürm-Interstadiale Brørup und Odderade, nachgewiesen werden konnten. Diese Übereinstimmung bestätigt nicht nur die Datierung der Ablagerungen vom Samerberg, sondern erlaubt auch den Schluß, daß Eem und Riß/Würm zeitgleiche Warmzeiten sind.

Low Mass X-ray Binaries and Metallicity Dependence: Story of Failures

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)

description: Observations of galactic and extra-galactic globular clusters have shown that on average metal-rich clusters are ~3 times as likely to contain a bright X-ray source than their metal-poor counterparts. We propose that this can be explained by taking into account the difference in the stellar structure of main sequence donors with masses between ~0.85 Msun and ~1.25 Msun at different metallicities. Metal-poor main sequence stars in this mass range do not have an outer convective zone while metal-rich stars do. The absence of this zone turns off magnetic braking, a powerful mechanism of orbital shrinkage, leading to the failure of dynamically formed main sequence - neutron star binaries to start mass transfer or appear as bright low-mass X-ray binaries.

description: The domestic poultry subsector in Nigeria is experiencing a dynamic growth and transformation. In just one decade, the volume of feed used in Nigeria increased by 600% from 300 thousand to 1.8 million tons. Using data from multiple sources, this brief presents some key findings from an initial exploration of this dynamic subsector. We combine data from secondary sources including the United Nations’ Comtrade data, FAO data and earlier empirical studies in Nigeria to information gathered through a rapid reconnaissance of the poultry subsector in the Ibadan area in 2015 and 20161 for our descriptive analysis. This is supported by an empirical analysis using a nationally representative panel dataset on agricultural production and household consumption in Nigeria in 2010 and 2012.

The base-e representation of numbers and the power law

Year: 2020
Subjects: subject: General Mathematics (math.GM)
subject: FOS: Mathematics

description: Some properties of the optimal representation of numbers are investigated. This representation, which is to the base-e, is examined for coding of integers. An approximate representation without fractions that we call WF is introduced and compared with base-2 and base-3 representations, which are next to base-e in efficiency. Since trees are analogous to number representation, we explore the relevance of the statistical optimality of the base-e system for the understanding of complex system behavior and of social networks. We show that this provides a new theoretical explanation for the nature of the power law exhibited by many open complex systems. In specific, we show that the power law distribution most often proposed for such systems has a form that is similar to that derived from the optimal base-e representation.

description: Es wird der Versuch unternommen, auf der Grundlage von Geländebeobachtungen und Literaturangaben eine Karte der mutmaßlichen Lößverbreitung in Oberitalien zu entwerfen. Dann werden fünf Interstadialböden beschrieben. Im Dora Ripária-Gebiet westlich Turin liegen zwei Würmlösse über dem letztinterglazialen, solifluidal umgelagerten Plastosol. Der untere ist zu einer Braunerde-Parabraunerde, der obere zu einer extrem sauren Parabraunerde verwittert. Auch der Löß auf den Rißmoränen des Dora Báltea-Gletschers gehört zwei Würmphasen an. Der darauf entstandene interstadiale und rezente Boden sind beides extreme Pseudogleye. Der fossile Boden ist reich an ehemaligen Frostspalten. Am Tessin konnte auf den Deckenschottern Riß- und Würmlöß gefunden werden. Der extrem pseudovergleyte Rißlöß ist in noch weit höherem Maße als der zu einer mäßig pseudovergleyten Braunerde verwitterte basale Würmlöß von einem Gitterwerk ehemaliger Frostspalten durchsetzt. Aus dem westlichen Gardasee-Gebiet werden zwei Solifluktionslösse über Rißmoräne beschrieben, von denen der untere zu einer Parabraunerde, der obere zu einer Parabraunerde-Braunerde verwitterte, östlich des Garda-sees wurde eine interstadiale Schwarzerdebildung angetroffen, die später zusammengeschwemmt und von Moränen überlagert wurde. Abschließend werden das Bildungsklima der fossilen Böden und ihre stratigraphische Einordnung diskutiert.

Magnetic behavior of a ferro-ferrimagnetic ternary alloy AB$_ρ$C$_{1-ρ}$ with a selective site disorder: the case study of a mixed-spin Ising model on a honeycomb lattice

description: Phase transitions, compensation phenomenon and magnetization of a ferro-ferrimagnetic ternary alloy AB$_ρ$C$_{1-ρ}$ composed of three different kinds of magnetic ions A, B and C with the spin magnitude 1/2, 1 and 3/2 are examined within the framework of a mixed-spin Ising model on a honeycomb lattice with a selective annealed site disorder on one of its two sublattices. It is supposed that the first sublattice of a bipartite honeycomb lattice is formed by the spin-1/2 magnetic ions, while the sites of the second sublattice are randomly occupied either by the spin-1 magnetic ions with a probability $ρ$ or the spin-3/2 magnetic ions with a probability $1-ρ$, both being subject to a uniaxial single-ion anisotropy. The model under investigation can be exactly mapped into an effective spin-1/2 Ising model on a triangular lattice through the generalized star-triangle transformation. For a specific concentration of the spin-1 (spin-3/2) magnetic ions, it is shown that the ferro-ferrimagnetic version of the studied model may display a compensation temperature at which the total magnetization vanishes below a critical temperature. The critical temperature strikingly may also become independent of the concentration of the randomly mixed spin-1 and spin-3/2 magnetic ions for a specific value of a uniaxial single-ion anisotropy. The spontaneous magnetic order may be notably restored at finite temperatures through the order-by-disorder mechanism above a disordered ground state, which results in an anomalous temperature dependence of the total magnetization with double reentrant phase transitions.

description: In information theory, the link between continuous information and discrete information is established through well-known sampling theorems. Sampling theory explains, for example, how frequency-filtered music signals are reconstructible perfectly from discrete samples. In this Letter, sampling theory is generalized to pseudo-Riemannian manifolds. This provides a new set of mathematical tools for the study of space-time at the Planck scale: theories formulated on a differentiable space-time manifold can be completely equivalent to lattice theories. There is a close connection to generalized uncertainty relations which have appeared in string theory and other studies of quantum gravity.

description: Radial velocities of 468 globular clusters around NGC 1399, the central galaxy in the Fornax cluster, have been obtained with FORS2 and the Mask Exchange Unit (MXU) at the ESO Very Large Telescope. This is the largest sample of globular cluster velocities around any galaxy obtained so far. The mean velocity uncertainty is 50 km/sec. This data sample is accurate and large enough to be used in studies of the mass distribution of NGC 1399 and the properties of its globular cluster system. Here we describe the observations, the reduction procedure, and discuss the uncertainties of the resulting velocities. The complete sample of cluster velocities which is used in a dynamical study of NGC 1399 is tabulated. A subsample is compared with previously published values.

description: We propose a hierarchical log Gaussian Cox process (LGCP) for point patterns, where a set of points x affects another set of points y but not vice versa. We use the model to investigate the effect of large trees to the locations of seedlings. In the model, every point in x has a parametric influence kernel or signal, which together form an influence field. Conditionally on the parameters, the influence field acts as a spatial covariate in the intensity of the model, and the intensity itself is a non-linear function of the parameters. Points outside the observation window may affect the influence field inside the window. We propose an edge correction to account for this missing data. The parameters of the model are estimated in a Bayesian framework using Markov chain Monte Carlo (MCMC) where a Laplace approximation is used for the Gaussian field of the LGCP model. The proposed model is used to analyze the effect of large trees on the success of regeneration in uneven-aged forest stands in Finland.

description: Ziel dieser Veröffentlichung ist es, für einen Abschnitt entlang des Albert Kanals in Niederländisch und Belgisch Limburg eine Übersicht zur Lössstratigraphie zu erstellen. Die Arbeit gründet sich vor allem auf Feldaufnahmen und Schwermineralanalysen. An Talhängen und zwischen Flussterrassen kam es zur Sedimentation und Erhaltung mächtiger, reich gegliederter Lössablagerungen. Die Wände des Albert Kanals, Lössaufschlüsse im angrenzenden Gebiet und vier große archäologische Ausgrabungen wurden untersucht. Auf Grund von charakteristischen lithologischen und paläopedologischen Leithorizonten, mineralogischen und chronologischen Daten und deren Korrelation mit Lössaufschlüssen in Hessen wurde eine lössstratigraphische Übersicht für die Zeit seit dem Holstein-Interglazial erstellt, welche sich mit Ozean- und Eisisotopenabfolgen sowie mit festländischen Pollenzonen korrelieren lassen. Es lassen sich vier glaziale Lösszyklen und fünf interglaziale Paläoböden auf der Rothem Terrasse der Maas ausmachen.

description: We apply the random phase approximation (RPA) and its extension called renormalized RPA to the quantum anharmonic oscillator with an O(2) symmetry. We first obtain the equation for the RPA frequencies in the standard and in the renormalized RPA approximations using the equation of motion method. In the case where the ground state has a broken symmetry, we check the existence of a zero frequency in the standard and in the renormalized RPA approximations. Then we use a time-dependent approach where the standard RPA frequencies are obtained as small oscillations around the static solution in the time-dependent Hartree-Bogoliubov equation. We draw a parallel between the two approaches.

description: Clostridium perfringens is a spore-forming anaerobic pathogen responsible for a variety of histotoxic and intestinal infections in humans and animals. High-resolution genotyping aiming to identify bacteria at strain level has become increasingly important in modern microbiology to understand pathogen transmission pathways and to tackle infection sources. This study aimed at establishing a publicly available genome-wide multilocus sequence-typing (MLST) scheme for C. perfringens. A total of 1,431 highly conserved core genes (1.34 megabases; 50% of the reference genome genes) were indexed for a core genome-based MLST (cgMLST) scheme for C. perfringens. The scheme was applied to 282 ecologically and geographically diverse genomes, showing that the genotyping results of cgMLST were highly congruent with the core genome-based single-nucleotide-polymorphism typing in terms of resolution and tree topology. In addition, the cgMLST provided a greater discrimination than classical MLST methods for C. perfringens. The usability of the scheme for outbreak analysis was confirmed by reinvestigating published outbreaks of C. perfringens-associated infections in the United States and the United Kingdom. In summary, a publicly available scheme and an allele nomenclature database for genomic typing of C. perfringens have been established and can be used for broad-based and standardized epidemiological studies. IMPORTANCE: Global epidemiological surveillance of bacterial pathogens is enhanced by the availability of standard tools and sharing of typing data. The use of whole-genome sequencing has opened the possibility for high-resolution characterization of bacterial strains down to the clonal and subclonal levels. Core genome multilocus sequence typing is a robust system that uses highly conserved core genes for deep genotyping. The method has been successfully and widely used to describe the epidemiology of various bacterial species. Nevertheless, a cgMLST typing scheme for Clostridium perfringens is currently not publicly available. In this study, we (i) developed a cgMLST typing scheme for C. perfringens, (ii) evaluated the performance of the scheme on different sets of C. perfringens genomes from different hosts and geographic regions as well as from different outbreak situations, and, finally, (iii) made this scheme publicly available supported by an allele nomenclature database for global and standard genomic typing.

Point X-ray Sources in Elliptical Galaxies

Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We analyze the upper-end X-ray luminosity function (XLF) observed in elliptical galaxies for point sources. We propose that the observed XLF is dominated by transient BH systems in outburst and the XLF shape reflects the black hole (BH) mass spectrum among old X-ray transients. The BH mass spectrum -- XLF connection depends on a weighting factor that is related to the transient duty cycle and depends on the host-galaxy age, the BH mass and the donor type (main sequence, red giant, or white dwarf). We argue that the assumption of a constant duty cycle for all systems leads to results inconsistent with current observations. The type of dominant donors in the upper-end XLF depends on what type of magnetic braking operates: in the case of ``standard'' magnetic braking, BH X-ray binaries with red-giant donors dominate, and in the case of weaker magnetic braking prescriptions main sequence donors dominate.

Next-to-leading mass singularities in two-loop electroweak singlet form factors
Creators: name: Pozzorini, S.
Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We consider virtual electroweak corrections to the form factors for massless chiral fermions coupling to an SU(2)xU(1) singlet gauge boson in the asymptotic region $s\gg M_W^2$, where the invariant mass $s$ of the external gauge boson is much higher than the weak-boson mass scale. Using the sector-decomposition method we compute mass singularities, which arise as logarithms of $s/M_W^2$ and $1/ε$ poles in $D=4-2ε$ dimensions, to one- and two-loop next-to-leading logarithmic accuracy. In this approximation we include all contributions of order $α^l ε^{k} log^{j+k}(s/M_W^2)$, with $l=1,2$ and $j=2l,2l-1$. We find that the electroweak two-loop leading- and next-to-leading-logarithmic mass singularities can be written in a form that corresponds to a generalization of Catani's formula for massless QCD.

description: We present here identification and characterization of the young stellar population associated with an active star-forming site Sh2-242. We used our own new optical imaging and spectroscopic observational data, as well as several archival catalogs, e.g., Pan-STARRS 1, $Gaia$ DR2, IPHAS, WIRCam, 2MASS, and $Spitzer$. Slit spectroscopic results confirm the classification of the main ionizing source BD+26 980 as an early-type star of spectral type B0.5 V. The spectrophotometric distance of the star is estimated as 2.08 $\pm$ 0.24 kpc, which confirms the source as a member of the cluster. An extinction map covering a large area (diameter $\sim$ 50') is generated with $H$ and $K$ photometry toward the region. From the map, three distinct locations of peak extinction complexes ($A_{V}$ $\simeq$ 7$-$17 mag) are identified for the very first time. Using the infrared color excess, a total of 33 Class I and 137 Class II young objects are classified within the region. The IPHAS photometry reveals classification of 36 H$α$ emitting sources, which might be class II objects. Among 36 H$α$ emitting sources, 5 are already identified using infrared excess emission. In total, 201 young objects are classified toward S242 from this study. The membership status of the young sources is further windowed with the inclusion of parallax from the $Gaia$ DR2 catalog. Using the optical and infrared color-magnitude diagrams, the young stellar objects are characterized with an average age of $\sim$ 1 Myr and the masses in the range 0.1$-$3.0 $M_\odot$. The census of the stellar content within the region is discussed using combined photometric and spectroscopic data.

description: We study four dimensional N=1 gauge theories that arise on the worldvolume of D3-branes probing complex cones over del Pezzo surfaces. Global symmetries of the gauge theories are made explicit by using a correspondence between bifundamental fields in the quivers and divisors in the underlying geometry. These global symmetries are hidden, being unbroken when all inverse gauge couplings of the quiver theory vanish. In the broken phase, for finite gauge couplings, only the Cartan subalgebra is manifest as a global symmetry. Superpotentials for these models are constructed using global symmetry invariants as their building blocks. Higgsings connecting theories for different del Pezzos are immediately identified by performing the appropriate higgsing of the global symmetry groups. The symmetric properties of the quivers are also exploited to count the first few dibaryon operators in the gauge theories, matching their enumeration in the AdS duals.

Geomorphologische Untersuchungen in der Lüneburger Heide haben ergeben, daß die in der Literatur vertretenen Auffassungen über die Entstehung des Geschiebedecksandes zu einseitig sind, sich aber insgesamt gesehen ergänzen: Der Geschiebedecksand ist aus Grundmoräne dadurch entstanden, daß diese nach ihrer Ablagerung je nach Lage, Mächtigkeit, Zusammensetzung und Alter unterschiedlichen kryogenen, solifluidalen, fluvialen, äolischen, pedogenen und biogenen Umwandlungsprozessen ausgesetzt war, so daß die ursprünglichen Merkmale der Moräne mehr oder weniger verlorengegangen sind.

description: Spin defects in silicon carbide (SiC) with mature wafer-scale fabrication and micro/nano-processing technologies have recently drawn considerable attention. Although room temperature single-spin manipulation of colour centres in SiC has been demonstrated, the typically detected contrast is less than 2%, and the photon count rate is also low. Here, we present the coherent manipulation of single divacancy spins in 4H-SiC with a high readout contrast (-30%) and a high photon count rate (150 kilo counts per second) under ambient conditions, which are competitive with the nitrogen-vacancy (NV) centres in diamond. Coupling between a single defect spin and a nearby nuclear spin is also observed. We further provide a theoretical explanation for the high readout contrast by analysing the defect levels and decay paths. Since the high readout contrast is of utmost importance in many applications of quantum technologies, this work might open a new territory for SiC-based quantum devices with many advanced properties of the host material.

Die Inlandeis-Theorie, seit 100 Jahren fester Bestandteil der Deutschen Quartärforschung
Creators: name: Kaiser, Karlheinz

Year: 1975

description: Vor allem die Begründungen von zwei Grundvorstellungen haben die Erforschungsgeschichte des quartären Eiszeitalters — und gleichfalls auch der präquartären Eiszeiten im Verlaufe der Erdgeschichte — maßgeblich bestimmt. Einmal fußt die im Klimawandel verankerte Sonderstellung des Quartärs gegenüber den älteren und weitaus länger andauernden Erdzeit-Systemen auf der Tatsache von einstmals weit ausgedehnteren Vergletscherungen auf der Erde. Die Auffassung von der periodischen Wiederkehr — mit dem daran geknüpften Wandel der Umweltbedingungen geologischer, geomorphologischer, klimatischer, hydrologischer, pedologischer und biogeographischer Art — solcher Vergletscherungen (Polyglazialismus) bildet hingegen die Grundlage unserer heutigen Quartärgliederung. Es bedurfte fast 100 Jahre, ehe sich diese Leitgedanken im Jahre 1875 bzw. zu Anfang der 20er Jahre dieses Jahrhunderts weltweit und endgültig durchzusetzen vermochten.

description: Traditional US rental housing data sources such as the American Community Survey and the American Housing Survey report on the transacted market - what existing renters pay each month. They do not explicitly tell us about the spot market - i.e., the asking rents that current homeseekers must pay to acquire housing - though they are routinely used as a proxy. This study compares governmental data to millions of contemporaneous rental listings and finds that asking rents diverge substantially from these most recent estimates. Conventional housing data understate current market conditions and affordability challenges, especially in cities with tight and expensive rental markets.

Lasing in a coupled hybrid double quantum dot-resonator system

description: We theoretically investigate the possibility of lasing in an electromagnetic resonator coupled to a voltage-biased hybrid double quantum dot comprised of a double quantum dot tunnel coupled simultaneously to a normal metal and a superconducting lead. Using a unitary transformation, we derive a resonator-double quantum dot interaction Hamiltonian in the rotating-wave approximation which reveals the fact that lasing in this system is mediated by electron transitions between Andreev energy levels in the system's density of states. Moreover, by employing a Markovian master equation incorporating dissipation effects for the electronic and photonic degrees of freedom, we numerically calculate the steady-state reduced density matrix of the system from which we determine the average photon number and its statistics in the resonator in various parameter regimes. We find that at some appropriate parameter configurations, lasing can be considerably enhanced due to the possibility of electron transitions between multiple Andreev levels in the system.
Vogelherd und Bocksteinschmiede im Lonetal

description: Die Faunen zweier neuerlich ausgegrabener Höhlen im Lonetal (Württemberg), der Bocksteinschmiede und des Vogelherds, werden verglichen. Die Tierreste sind größtenteils vom Menschen in die Höhlen hineingeschafft worden. Im Vogelherd sind mindestens 180 Tiere überliefert, in der Bocksteinschmiede mindestens 250. Sie werden, zu größeren Gruppen zusammengefaßt, gemäß ihrer prozentualen Häufigkeit graphisch dargestellt. Trotz weitgehend zufälliger Erhaltung der Reste ist die Zusammensetzung der beiden Faunen im Großen und Ganzen ähnlich und vergleichbar. Bestehende Unterschiede lassen sich teilweise durch Lage und Gestalt der Höhlen erklären.

title: Boundedness, Belonging and Becoming: Primary School Children's Perspectives of Education and Learning in the South Wales Valleys
Creators: name: Williams, Gavin
Publisher: name: The Open University
Year: 2019

description: The impact of poverty and disadvantage on the attainment and outcomes of children is well documented. Less research evidence is available on the experiences of children living in deprived communities and their perceptions of its impact on learning and future life chances. Using a case study approach, this thesis investigates the experiences of children living in the Rhondda Valley, a post-industrial area in South Wales. Nineteen children (aged eleven) from three primary schools in the valley participated in the study using focus groups, individual interviews, photo-elicitation interviews and observation to explore their experiences and perceptions of growing up in the area and how it affected learning. Drawing on Bourdieu’s Theory of Practice (1984), it was found that the topography and geographically bounded nature of the valley significantly affected the children’s experiences. It not only shaped the immediate formal and informal learning opportunities available but the history and culture of the area. Furthermore, the study revealed the children’s awareness of the importance of formal education for their futures. Another key finding was the role of the family in instilling a feeling of belonging to the area, and supporting the children to access informal learning opportunities within and outside the boundaries of the valley. The influence of the landscape, school, and family was clear in the children’s expressions of becoming. This aspirational habitus demonstrated agency and an ability to draw upon their experiences and look beyond the valley boundaries, thus challenging governmental policy that is often written from a perspective of cultural deficit. The research provides new insights into the learning experiences of children growing up in a deprived area. It has implications for policy development in identifying the importance of gaining children’s views and for educational practice in highlighting the importance of the natural environment and local history for learning.

description: Anticipating human motion in crowded scenarios is essential for developing intelligent transportation systems, social-aware robots and advanced video surveillance applications. A key component of this task is represented by the inherently multi-modal nature of human paths which makes socially acceptable multiple futures when human interactions are involved. To this end, we propose a generative architecture for multi-future trajectory predictions based on Conditional Variational Recurrent Neural Networks (C-VRNNs). Conditioning mainly relies on prior belief maps, representing most likely moving directions and forcing the model to consider past observed dynamics in generating future positions. Human interactions are modeled with a graph-based attention mechanism enabling an online attentive hidden state refinement of the recurrent estimation. To corroborate our model, we perform extensive experiments on publicly-available datasets (e.g., ETH/UCY, Stanford Drone Dataset, STATS SportVU NBA, Intersection Drone Dataset and TrajNet++) and demonstrate its effectiveness in crowded scenes compared to several state-of-the-art methods.

Evolution of the West Andean Escarpment at 18°S (N. Chile) during the last 25 Ma: uplift, erosion and collapse through time

description: The geological record of the Western Andean Escarpment (WARP) reveals episodes of uplift, erosion, volcanism and sedimentation. The lithological sequence at 18°S comprises a thick pile of Azapa Conglomerates (25–19 Ma), an overlying series of widespread rhyodacitic Oxaya Ignimbrites (up to 900 m thick, ca. 19 Ma), which are in turn covered by a series of mafic andesite shield volcanoes. Between 19 and 12 Ma, the surface of the Oxaya Ignimbrites evolved into a large monocline on the western slope of the Andes. A giant antithetically rotated block (Oxaya Block, 80 km×20 km) formed on this slope at about 10–12 Ma and resulted in an easterly dip and a reversed drainage on the block's surface. Morphology, topography and stratigraphic observations argue for a gravitational cause of this rotation. A “secondary” gravitational collapse (50 km3), extending 25 km to the west occurred on the steep western front of the Oxaya Block. Alluvial and fluvial sediments (11–2.7 Ma) accumulated in a half graben to the east of the tilted block and were later thrust over by the rocks of the escarpment wall, indicating further shortening between 8 and 6 Ma. Flatlying Upper Miocene sediments (<5.5 Ma) and the 2.7 Ma Lauca–Peréz Ignimbrite have not been significantly shortened since 6 Ma, suggesting that recent uplift is at least partly caused by regional tilting of the Western Andean slope.
An alpha-stable approach to the study of the P(D) distribution of unresolved point sources in CMB sky maps

description: We present a new approach to the statistical study and modelling of number counts of faint point sources in astronomical images, i.e. counts of sources whose flux falls below the detection limit of a survey. The approach is based on the theory of alpha-stable distributions. We show that the non-Gaussian distribution of the intensity fluctuations produced by a generic point source population -- whose number counts follow a simple power law -- belongs to the alpha-stable family of distributions. Even if source counts do not follow a simple power law, we show that the alpha-stable model is still useful in many astrophysical scenarios. With the alpha-stable model it is possible to totally describe the non-Gaussian distribution with a few parameters which are closely related to the parameters describing the source counts, instead of an infinite number of moments. Using statistical tools available in the signal processing literature, we show how to estimate these parameters in an easy and fast way. We demonstrate that the model proves valid when applied to realistic point source number counts at microwave frequencies. In the case of point extragalactic sources observed at CMB frecuencies, our technique is able to successfully fitting the P(D) distribution of deflections and to precisely determining the main parameters which describe the number counts. In the case of the Planck mission, the relative errors on these parameters are small either at low and at high frequencies. We provide a way to deal with the presence of Gaussian noise in the data using the empirical characteristic function of the P(D). The formalism and methods here presented can be very useful also for experiments in other frequency ranges, e.g. X-ray or radio Astronomy.
