description: We prove some properties of the Kruskal-Katona function, and apply to the following variation of cross-intersecting antichains. Let $n\ge 4$ be an even integer and $\mathscr{A}$ and $\mathscr{B}$ be two cross-intersecting antichains of $\mathbb{N}_n$ with at most $k$ disjoint pairs, i.e. for all $A_i\in \mathscr{A}$, $B_j\in\mathscr{B}$, $A_i\cap B_j=\emptyset$ only if $i=j\le k$. We prove a best possible upper bound on $|\mathscr{A}|+|\mathscr{B}|$. Furthermore, we show that the extremal families contain only $\frac{n}{2}$ and $(\frac{n}{2}+1)$-sets.

description: Photoluminescence (PL) has been used to study two-dimensional incompressible electron liquids in high magnetic fields for nearly two decades. However, some of the observed anomalies coincident with the fractional quantum Hall effect are still unexplained. We show that emission in these systems occurs from fractionally charged "quasiexciton" states formed from trions correlated with the surrounding electrons. Their binding and recombination depend on the state of both the electron liquid and the involved trion, predicting discontinuities in PL and sensitivity to sample parameters.

description: Die Beschreibung und Modellierung des Baugrundes erweist sich aufgrund seiner Genese als schwierig. Diese Tatsache soll am Beispiel eines Gründungsentwurfs, durch die Gegenüberstellung zweier unterschiedlicher Modellansätze demonstriert werden. In diese Betrachtung gehen zum einen "Subjektive Schätzungen" und zum anderen "[Geo]Statistische Baugrundmodelle" ein. Die Bemessung erfolgt anhand einer identischen Ausgangsdatenbasis. Im Ergebnis zeigen sich große Abweichungen zwischen beiden Modellansätzen, die sich auf unterschiedlichen Umgang mit den streuenden Baugrundkenngrößen zurückführen lassen. Die streuenden Baugrundkenngrößen werden bei den "Subjektiven Schätzungen" durch einen einzigen, ungünstig wirkenden Kennwert repräsentiert, der die Eigenschaften eines Homogenbereichs beschreibt. Bei den "[Geo]Statistischen Baugrundmodellen" werden die Baugrundkenngrößen in ihrer Streubreite erfasst, ausgewertet und mit der Monte-Carlo-Simulation in der Grenzzustandsfunktion berücksichtigt.

description: George E Lock was the grandfather of Iain Lock, who contributed these artefacts. George joined the British Army at the start of the first World War. In 1917, at the age of 27, he fought in the Battle of Passchendaele. On the 9th October, he acted as a stretcher bearer, and worked for an incredible seventy-four hours, during which he brought over twenty injured men from shell holes. Three times his fellow stretcher bearers were either killed or injured by snipers, however George kept going bravely. For his actions, he won a Distinguished Conduct Medal, which is just one level down from the Victoria Cross, on the 1st of November 1917. On top of this, when he returned from the war, he was presented with a pocket watch by the tailoring company he worked for as a gift of appreciation.

description: We investigate a possibility of neutralino dark matter (DM) direct detection in the future electron accelerators. That is counting of high p_T electron recoil events by neutralinos in halo. If selectron and neutralino masses would be precisely measured in future collider experiments, the beam energy could be tuned so that the scatterings are dominated by on-pole selectron exchange. When selectron and neutralino mass difference is smaller than O(10) GeV, the elastic cross section exceeds over micro barn. Discovery of the high p_T electron events would be a firm prove of the neutralino DM component in halo. In the experiment, the electron beam energy must be tuned within O(10) MeV and the electron beam with high currents of O(100)A is required for the detectors of the total length of a few hundred meters so that the sufficient event rate is obtained. The dependence of the event rate on the DM velocity distribution in halo is also discussed. This method might be applicable to other DM candidates.

description: Context. Asymptotic giant branch stars are cool luminous evolved stars that are well observable across the Galaxy and populating Gaia data. They have complex stellar surface dynamics Aims. On the AGB star CL Lac, it has been shown that the convection-related variability accounts for a substantial part of the Gaia DR2 parallax error. We observed this star with the MIRC-X beam combiner installed at the CHARA interferometer to detect the presence of stellar surface inhomogeneities. Methods. We performed the reconstruction of aperture synthesis images from the interferometric observations at different wavelengths. Then, we used 3D radiative hydrodynamics simulations of stellar convection with CO5BOLD and the post-processing radiative transfer code Optim3D to compute intensity maps in the spectral channels of MIRC-X observations. Then, we determined the stellar radius and compared the 3D synthetic maps to the reconstructed ones focusing on matching the intensity contrast, the morphology of stellar surface structures, and the photocentre position at two different spectral channels, 1.52 and 1.70 micron, simultaneously. Results. We measured the apparent diameter of CL Lac at two wavelengths and recovered the radius using a Gaia parallax. In addition to this, the reconstructed images are characterised by the presence of a brighter area that largely affects the position of the photocentre. The comparison with 3D simulation shows good agreement with the observations both in terms of contrast and surface structure morphology, meaning that our model is adequate for explaining the observed inhomogenities. Conclusions. This work confirms the presence of convection-related surface structures on an AGB star of Gaia DR2. Our result will help us to take a step forward in exploiting Gaia measurement uncertainties to extract the fundamental properties of AGB stars using appropriate RHD simulations.

description: This is about the contributor's father, Frederick Thursby, who served in the Royal Navy. Frederick Thursby was a commander and navigator who blew up mines. Included here is a picture of Frederick aged 24 in the Russian Baltic and another of him in his uniform in Gosport. In 1919, he jumped overboard, saving the crew, for which he was promoted to Lieutenant when he was originally a Midshipman. Unfortunately, however, his medal was stolen. He used to board the ships in Plymouth and, every time he set sail, his wife would go to the top of the hill and wave her handkerchief until the ship had gone. Her name was Winifred Emma Southerton and she lived in Henley House which, because of its size, was used as a hospital.

The observables of the two-body subsystems, $NN$ and $ΣN$, are well reproduced. We do not find $ΣNN$ bound states, but there are two attractive channels with a resonance close above the three-body threshold. These channels are the $(I,J)=(1,1/2)$ and $(0,1/2)$, their quantum numbers, widths and energy ordering consistent with the recently measured strange tribaryons from the $^{4}{\rm He}(K_{\rm stopped}^{-},N)$ reactions in the KEK PS E471 experiment.

BPS preons in supergravity and higher spin theories. An overview from the hill of twistor appraoch
Creators: name: Bandos, Igor A.
Publisher: name: arXiv
Year: 2005
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We review briefly the notion of BPS preons, first introduced in 11-dimensional context as hypothetical constituents of M-theory, in its generalization to arbitrary dimensions and emphasizing the relation with twistor approach. In particular, the use of a 'twistor-like' definition of BPS preon (almost) allows us to remove supersymmetry arguments from the discussion of the relation of the preons with higher spin theories and also of the treatment of BPS preons as constituents. We turn to the supersymmetry in the second part of this contribution, where we complete the algebraic discussion with supersymmetric arguments based on the M-algebra (generalized Poincare superalgebra), discuss the possible generalization of BPS preons related to the osp(1|n) (generalized AdS) superalgebra, review a twistor-like kappa-symmetric superparticle in tensorial superspace, which provides a point-like dynamical model for BPS preon, and the role of BPS preons in the analysis of supergravity solutions. Finally we describe resent results on the concise superfield description of the higher spin field equations and on superfield supergravity in tensorial superspaces.

description: We have investigated the nonlinear amplitude vector equation governing the evolution of optical pulses in optical and UV region. We are normalizing this equation for the cases of different and equal transverse and longitudinal size of optical pulses, of week and strong dispersion. This gives us the possibility to reduce the amplitude equation to different nonlinear evolution equations in the partial cases. For some of these nonlinear equations exact vortex solutions are found. Conditions for experimental observations of these vortices are determined.

description: Im Rahmen dieser Diplomarbeit werden die diffusen Phosphoreinträge am Beispiel des Einzugsgebietes der oberen Rur bilanziert . Im theoretischen Teil dieser Diplomarbeit werden die Grundlagen für die Darstellung des Nährstofftransportes erarbeitet. Dabei erfolgt die Beschreibung der Eintragswege von Phosphor in die Gewässer, die Herkunft und Art von Phosphoreinträgen sowie die wichtigen Eintragspfade der diffusen Phosphoreinträge. Mit diesen gewonnenen Erkenntnissen ist es möglich, den Stofftransport einschließlich der ablaufenden Prozesse mittels mathematischer Gleichungen über die Eintragspfade zu simulieren. Somit gelingt es, die Funktionsweise und die Anwendbarkeit, der zum Einsatz kommenden aktuellen Wasser- und Stofftransportmodelle zur Quantifizierung diffuser Phosphoreinträgen zu verstehen. Im praktischen Teil dieser Diplomarbeit werden die diffusen Phosphoreinträge im Einzugsgebiet der oberen Rur unter Hilfenahme der zuvor ermittelten Grundlagen bilanziert. Dabei ist es nötig, das Einzugsgebiet zu beschreiben, abzugrenzen und die enthaltenen Gewässer zu beleuchten. Weiterhin erfolgte eine Recherche der im Einzugsgebiet vorhandenen Flächennutzungen, um die Bilanzierung mit den aus der Literatur ermittelten Gleichungen und Werten durchführen zu können. Das Ergebnis ist eine Phosphorjahresfracht mit der das Einzugsgebiet bewertet werden kann.

description: We study the low-energy transport properties of a hybrid device composed by a native quantum dot coupled to both ends of a topological superconducting nanowire section hosting Majorana zero-modes. The account of the coupling between the dot and the farthest Majorana zero-mode allows to introduce the topological quality factor, characterizing the level of topological protection in the system. We demonstrate that Coulomb interaction between the dot and the topological superconducting section leads to the onset of the additional overlap of the wavefunctions describing the Majorana zero-modes, leading to the formation of trivial Andreev bound states even for spatially well-separated Majoranas. This leads to the spoiling of the quality factor and introduces a constraint for the braiding process required to perform topological quantum computing operations.

description: In this documentation a general model for combined normal/shear cracking will be presented. Basically it is defined of the normal and shear stresses of a cohesive crack with the corresponding displacements in normal and tangential direction. For the load state there can be considered three cases of loading: pure tension, shear-tension and shear-compression. In the softening state of quasi-brittle materials like concrete there are be mould physical effects like dilatancy by shearing deformations, nevertheless no dilatancy under very high compression can be performed. By this way it is additionally possible to simulate extended roughness at the contact surface besides the coulomb criteria as it exists in real cracking deformations of structures characterized by sensitive material behavior. To enable this goal in context of smeared crack analysis a special feature in combined activating Mode I and Mode II fracture energies (mixed mode cracking) is used. \\ After presenting this model a direct way for implementation as a constitutive law based for interface elements will be realized. Integrating this to the stochastic FE software SLang - The Structural Language some tests for verificating the interface model (by comparing the numerical results with existing experimental data) will be performed as well as discussing the cracking model with regard to practical aspects.

description: In coherent X-ray diffraction microscopy the diffraction pattern generated by a sample illuminated with coherent x-rays is recorded, and a computer algorithm recovers the unmeasured phases to synthesize an image. By avoiding the use of a lens the resolution is limited, in principle, only by the largest scattering angles recorded. However, the imaging task is shifted from the experiment to the computer, and the algorithm's ability to recover meaningful images in the presence of noise and limited prior knowledge may produce aberrations in the reconstructed image. We analyze the low order aberrations produced by our phase retrieval algorithms. We present two methods to improve the accuracy and stability of reconstructions.

A fuzzy expert system for acid rock drainage site remediation
Creators: name: Balcita, Judita Veronika
Publisher: name: University of British Columbia
Year: 2009

description: This thesis describes the development of an expert system using fuzzy logic-based techniques to deal with the remediation of Acid Rock Drainage contaminated sites. Acid Rock Drainage (ARD) is one of the major environmental challenges faced today by the mining industry. The interdisciplinary nature of ARD, involving biology, chemistry, geology, and mining knowledge is not yet fully understood nor has a viable and permanent solution to the problem been found. Development of a fuzzy expert system for ARD is considered useful in producing a standardized, yet adaptable, approach to the problem which can be used to generate quick advice to the user in a field where expertise is lacking. A fuzzy expert system can deal with missing, inaccurate, or heuristic data. A fuzzy expert system actually thrives on such conditions. Fuzzy sets are defined as the degree of belief in a particular qualitative concept as a function of one or more quantitative values. Rules are developed from these fuzzy sets during interviews with a chosen expert in the field. From user input on site data and site characterization, association within these rules of the degrees of belief in different concepts can flow through the system to generate a decision or conclusion. The system includes a fuzzy controller, separate control modules for treatment options and interactive hypertext documents for user control. The controller and control modules work together to follow the decision-making process of experts in the field in choosing appropriate remediation options for a site of possible or existing ARD. The hypertext documents are set up as user help resources and to provide system output information. They can also serve as teaching aids on treatment of ARD or to obtain better understanding of the possibility of implementing a treatment system. Validation and verification of the system has been carried out by comparing the results obtained for certain specific case studies with those determined by an expert.

description: Este trabalho estuda o turismo literário criativo, bem como as potencialidades deste tipo de turismo para os destinos turísticos, em geral, e para os turistas literários, em específico, e as formas como este turismo pode potencializar benefícios par os destinos turísticos e os turistas literários. Deste modo, a reflexão encontra-se dividida em duas partes: a primeira, de índole mais teórica, incide sobre considerações que delimitam o conceito de turismo literário criativo e sobre as suas particularidades; a segunda, de pendor mais prático, encontra-se ligada ao caso particular da cidade de Coimbra literária e de Miguel Torga. Coimbra possui bons recursos e produtos sustentáveis para uma procura mais ou menos especializada, com testemunhos materiais e imateriais da presença, ao longo dos tempos, de vários escritores. Nesse âmbito, propõe-se uma rota literária criativa em Coimbra, baseada no caso do escritor Miguel Torga, que viveu e morreu em Coimbra.

description: Die Instandsetzung historischer Gebäude ist ein komplexes und umfangreiches Thema. In der vorliegenden Arbeit wurde versucht, einen Überblick zu schaffen, indem die Vorgehensweise bei der Sanierung an einem konkreten Beispiel, der Kirche in Ehringsdorf, nachvollzogen wurde. Dieses Gebäude ist etwa 700 Jahre alt. Im Westen befindet sich ein ungefähr 100 Jahre alter Anbau; dort sind große Risse an den Fassaden sichtbar. Nach gründlicher Recherche, auch anhand eines vorhandenen Baugrundgutachtens, stellte sich heraus, dass diese Schäden dadurch verursacht wurden, dass die Gründung des Anbaus im Gegensatz zu der des alten Gebäudeteils nicht bis in eine tragfähige Bodenschicht reicht. Daher sinkt der Anbau durch Setzungen im Boden ab und es entstehen Zugspannungen im Mauerwerk, so dass es reißt. Da es sich also um ein Gründungsproblem handelt, nimmt die Sanierung der Gründung in der Bearbeitung der Varianten einen großen Teil ein. Es wird die Anwendung des Düsenstrahlverfahrens empfohlen. Die vorliegenden Berechnungen und Annahmen zu Baugrundkennwerten sollten noch durch Einbringen von Probesäulen überprüft werden. Außerdem muss eine geeignete Bindemittelzusammensetzung gewählt werden. Um Aussagen zur Sanierung des Mauerwerkes treffen zu können, fehlen wichtige Angaben zum Zustand und Aufbau. In der weiteren Planung sollte daher zunächst das Mauerwerk mit Hilfe einer Endoskopie untersucht werden. Außerdem sollten die Rissbreiten über einen Zeitraum von mindestens einem Jahr regelmäßig gemessen werden, um Veränderungen und eine tendenzielle Entwicklung feststellen zu können. Auf Grundlage der Ergebnisse kann dann entschieden werden, ob eine Vermörtelung der Risse ausreicht oder ob eine Mauerwerksinjektion zur Verfestigung erforderlich ist.

description: X-ray observations have revealed in other galaxies a class of extra-nuclear X-ray point sources with X-ray luminosities of $10^{39}$--$10^{41}$ erg/sec, exceeding the Eddington luminosity for stellar mass X-ray binaries. These ultra-luminous X-ray sources (ULXs) may be powered by intermediate mass black hole of a few thousand $M_\odot$ or stellar mass black holes with special radiation processes. In this paper, we present a survey of ULXs in 313 nearby galaxies with $D_{25}$$>$$1^\prime$ within 40 Mpc with 467 ROSAT HRI archival observations. The HRI observations are reduced with uniform procedures, refined by simulations that help define the point source detection algorithm employed in this survey. A sample of 562 extragalactic X-ray point sources with $L_X = 10^{38}$--$10^{43}$ erg/sec is extracted from 173 survey galaxies, including 106 ULX candidates within the $D_{25}$ isophotes of 63 galaxies and 110 ULX candidates between 1--2$\times D_{25}$ of 64 galaxies, from which a clean sample of 109 ULXs is constructed to minimize the contamination from foreground or background objects. In a subsequent paper, the statistic properties of the survey will be studied to calculate the occurrence frequencies and luminosity functions for ULXs in different types of galaxies to shed light on the nature of these enigmatic sources.

Generalist Repository Ecosystem Initiative (GREI)
Generalist Repository
Open Data

description: The NIH Generalist Repository Ecosystem Initiative (GREI), gave a presentation at SciDataCon in Salzburg in 2023 titled “Generalist repository ‘coopetition’ to enhance data sharing and discovery.” In that session, the seven generalist repositories participating in GREI (Dataverse, Dryad, Figshare, Mendeley Data, Open Science Framework, Vivli, and Zenodo) presented our collaborative way of working together towards common standards for metadata and metrics, interoperability and discovery across repositories, and community outreach and training. We also solicited feedback on GREI’s efforts and priorities from the RDA and SciDataCon audience. 

In this BoF session, we built on a larger effort of the NIH Office of Data Science Strategy to understand the role of generalist repositories in the larger data ecosystem including with respect to discipline-specific repositories, institutional repositories, research community practices, emerging standards for research data and repositories, and infrastructure providers (e.g. PIDs, storage, search).  A 2020 Workshop hosted by NIH ODSS titled “The Role of Generalist Repositories to Enhance Data Discoverability and Reuse” laid the groundwork for the GREI program, and now in the 3rd year of GREI we endeavored to engage the RDA community in the discussion as well. The GREI project impacts researchers globally, as all participating repositories are freely available for data deposition by all researchers.

At this initial BoF session we sought to hear perspectives from the RDA community about the role of generalist repositories in the global data landscape, including how generalist repositories may adopt and help set global standards for data sharing and reuse. We hoped to identify use cases, repository functionality, or data or repository standards that generalist repositories could be leaders in, to support progress in the research data ecosystem. In turn, we evaluated the feedback received during this session to prioritize future GREI work and determine whether an RDA IG or WG on the topic would be worthwhile in order to enable the repositories to collaborate and align longer term, while avoiding duplication of efforts.
Idea Laboratories: Providing Tools for Creative Tourism Agents

description: In Portugal, the project CREATOUR - Creative Tourism Destination Development in Small Cities and Rural Areas - has been working with a range of cultural/creative organizations (pilots) that are implementing new creative tourism experiences in the Portuguese territory. To improve their offers, CREATOUR carried out, between April 2017 and May 2019, a series of Idea Laboratories as a means to support content development, readjust and discuss pilot initiatives, and exchange experience and knowledge. These IdeaLabs focused on collaborative processes that accompanied all stages of the development of a creative tourism activity, from ideation to prototyping. One of the major needs was to establish a series of instruments to make a critical assessment of the laboratories' outcomes, to better understand if this type of collaborative process can be helpful in the designing of cultural tourism activities. This paper intends to disclosure the methodology used and the instruments created to evaluate the eficiency of the IdeaLabs and to present the results of such evaluation in a qualitative and comprehensive approach. By creating a methodology and a series of instruments, the evaluation process assessed the impacts of the IdeaLabs in the participants' ideas and strategies, and allowed us to better understand the creative and cultural organization's needs when implementing creative tourism experiences.

description: Similar to thermodynamic phase transitions in matter, readily apparent changes in optical response arise in the transition from isotropic to anisotropic optical phases. Treating the anisotropy of the dielectric permittivity as a control parameter, which changes continuously from zero to a nonzero finite value at the transition, in this work we describe the resulting effect on light propagation.
 We begin by investigating a simple case of the manifestations of such optical transition in lossy media. In the presence of loss, isotropic materials do not support Brewster phenomenon, however, if one changes the anisotropy continuously, the exact zero in the reflection at the Brewster incidence angle is recovered. Next, in the case of uniaxial anisotropy, we uncover dramatic changes in far-field thermal radiation induced by the transitions between metal, dielectric, and hyperbolic optical regimes that can be observed in the same material. We demonstrate that continuous evolution between different ''phases'' in the electromagnetic response imprints a characteristic signature in the far-field thermal emission. Finally, we show that the evolution of the optical anisotropy from uniaxial to biaxial symmetry brings qualitatively new optical modes which are different from the conventional propagating and evanescent fields. These emergent ''ghost'' waves offer a unique way to control mode interactions in optical systems. Our work uncovers the connection between the macroscopic properties of the optical materials and the transitions between different regimes of the electromagnetic response in these media. At last, we propose a range of potential applications of the resulting phenomena, from perfect absorption in lossy media to thermal radiation and optical sensing.

description: We calculate the one-loop flavor violating top quark decay t -> cgg in the Minimal Supersymmetric Standard Model. We discuss the branching ratios obtained with minimal flavor violation, as well as with soft-supersymmetry induced general flavor violation. Based on this rate we calculate the cross section for the single top quark production via gluon fusion, gg -> t cbar, and evaluate its contribution to the cross section for single top quark production in pp collisions at the Large Hadron Collider. We calculate all contributions coming from the standard model and charged Higgs loops, as well as gluino (and neutralino)-up-type squarks, and chargino-down-type squarks loops. Our numerical results show that the gluino and the chargino contributions are largest over the whole parameter range in the unconstrained Minimal Supersymmetric Standard Model. While in general the gluino contributions dominate the cross section, this result depends on the supersymmetric flavor violating parameters in the up and down squark sector, the relative mass of the gauginos, and whether or not the Grand Unified Theory relationships between gaugino masses are satisfied. In the most promising scenarios, the pp -> t cbar + tbar c + X cross section at the Large Hadron Collider can reach a few hundreds fb.

The Linearity of the Wesenheit function for the Large Magellanic Cloud Cepheids

description: There is strong evidence that the period-luminosity (PL) relation for the Large Magellanic Cloud (LMC) Cepheids shows a break at a period around 10 days. Since the LMC PL relation is extensively used in distance scale studies, the non-linearity of the LMC PL relation may affect the results based on this LMC calibrated relation. In this paper we show that this problem can be remedied by using the Wesenheit function in obtaining Cepheid distances. This is because the Wesenheit function is linear although recent data suggests that the PL and the period-colour (PC) relations that make up the Wesenheit function are not. We test the linearity of the Wesenheit function and find strong evidence that the LMC Wesenheit function is indeed linear. This is because the non-linearity of the PL and PC relations cancel out when the Wesenheit function is constructed. We discuss this result in the context of distance scale applications. We also compare the distance moduli obtained from mu_0=mu_V-R(mu_V-mu_I) (equivalent to Wesenheit functions) constructed with the linear and the broken LMC PL relations, and find that the typical difference in distance moduli is ~ +-0.03mag. Hence, the broken LMC PL relation does not seriously affect current distance scale applications. We also discuss the random error calculated with equation mu_0=mu_V-R(mu_V-mu_I), and show that there is a correlation term that exists from the calculation of the random error. The calculated random error will be larger if this correlation term is ignored.

description: Eric Alfred Busby served in the Royal Navy. He wrote letters to his grandchildren, one of whom contributed these and the photograph of Eric and his father, as a set of memoirs. They contain a description of surviving an explosion on a ship as a result of a collision with an American ship (potentially USS Manley), which set off depth charges. His brother, Arthur Ernest Busby, also fought. He joined the Yorkshire Dragoons and served in the cavalry. Arthur was injured at Passchendaele, when his horse was shot from beneath him. He was also in a trench which got shelled, killing four of the six men there. Arthur was subsequently invalided home and trained to become a pilot, although the War ended before he passed his exam. He had lots of shrapnel embedded in his skin which would come out when he shaved. When asked what it was, Arthur would reply, "A present from the Kaiser."
