description: objetiva-se analisar a evolução do modo de produção dos produtores do Assentamento Grossos em Canindé-Ceará. A pesquisa tem como delineamento o estudo de caso, recorrendo as concepções das pesquisas etnográfica e participava. Os dados, de origem primária, foram coletados mediante aplicação de questionários.Os dados secundários são provenientes de documentos oficiais. Para análise dos dados recorreu-se a uma abordagem qualitativa.Os resultados mostraram que, à época da Fazenda, como moradores, os agricultores estavam submetidos a um modo de produção que os explorava. Historicamente, a passagem da fazenda Grossos para Assentamento Grossos alterou o modo de produção, pois o assentado conquistou o seu espaço agrário, a terra, adquiriu novos instrumentos de trabalho e as relações de produção passaram de morador/patrão para agricultor proprietário de sua terra. Como destaques práticos, ressalta-se a importância de se analisar a evolução no modo de produção antes de qualquer intervenção, assim como forma de melhor adequar as políticas públicas voltadas para as comunidades rurais, considerando-se o modo de produção praticado. Para um modo diferente de produzir, exigem-se políticas diversificadas que levem em conta essas particularidades.

description: We compute masses of positive parity spin-$1/2$ and $3/2$ baryons composed of $u$, $d$, $s$, $c$ and $b$ quarks in a quark-diaquark picture. The mathematical foundation for this analysis is implemented through a symmetry-preserving Schwinger-Dyson equations treatment of a vector-vector contact interaction, which preserves key features of quantum chromodynamics, such as confinement, chiral symmetry breaking and low energy Goldberger-Treiman relations. This study requires a computation of diquark correlations containing these quarks which in turn are readily inferred from solving the Bethe-Salpeter equations of the corresponding mesons. Therefore, it serves as a unified formalism for a multitude of mesons and baryons. It builds on our previous works on the study of masses, decay constants and form factors of quarkonia and light mesons, employing the same model. We use two sets of parameters, one which remains exactly the same for both the light and heavy sector hadrons, and another where the coupling strength is allowed to evolve according to the available mass scales of quarks. Our results are in very good agreement with the existing experimental data as well as predictions of other theoretical approaches whenever comparison is possible.

description: Das Quartär der Bodensee-Region besteht aus Schottern frühpleistozäner alpiner Flusssysteme (Deckenschotter) sowie aus glazialen und Schmelzwasser-Ablagerungen der mittel- und spätpleistozänen Eiszeiten. Sie belegen den landschaftlichen Wandel von einer Art Rampe aus Vorbergen hin zur heutigen Topographie mit ineinander greifenden, übertieften Becken, sodass sich eine Art Amphitheater ergibt. Die Deckenschotter als älteste Ablagerungen dokumentieren einerseits die Eintiefung der alpinen Flüsse in diversen Terrassenstufen im Sedimentationsgebiet, andererseits durch deutliche Unterschiede im Geröllspektrum die Vergrößerung des Liefergebiets des sich entwickelnden alpinen Rheins. Der älteste Till kommt vor in Kontakt mit Mindel-Deckenschottern, es gibt jedoch keine Hinweise auf eine glaziale Übertiefung in dieser Zeit. Die meisten glazialen und Schmelzwasser-Ablagerungen werden drei großen Vergletscherungen des Rheingletschers zugeordnet. Diese Vorlandvergletscherungen sind mit drei Generationen glazialer Becken verknüpft. Die ältesten Becken sind zur Donau orientiert, die aus der letzten Vereisung entwässern zum Rhein. Diese Reorientierung bewirkte die hervorragende räumliche Auflösung der Sedimente und Formen. Traditionell wurden die Sedimente in einem chronostratigraphischen System aus glazialen und interglazialen Stufen beschrieben. Unsere Ziele in dieser Arbeit sind, eine Aktualisierung des chronostratigraphischen Systems vorzustellen, das neue, beim geologischen Dienst von Baden-Württemberg angewandte, lithostratigraphische Schema zu erklären und die wichtigsten neuen Einheiten kurz zu beschreiben.

description: I demonstrate a pairing mechanism of dopants in a magnetic lattice, emerging from the underlying high-temperature disorder of the spins. The effect is demonstrated in a mixed-dimensional model, where dopants travel along a two-leg ladder, while the spins feature Ising interactions along the rungs and the legs of the ladder. The dynamics following the sudden immersion of two nearest neighbor dopants in an infinite temperature spin lattice shows that thermal spin disorder frustrates the relative motion of the dopants and enforces them to co-propagate. The predictions are shown to be realistically testable in quantum simulation experiments.

description: Recurrent Neural Networks are an effective and prevalent tool used to model sequential data such as natural language text. However, their deep nature and massive number of parameters pose a challenge for those intending to study precisely how they work. We present a visual technique that gives a high level intuition behind the semantics of the hidden states within Recurrent Neural Networks. This semantic encoding allows for hidden states to be compared throughout the model independent of their internal details. The proposed technique is displayed in a proof of concept visualization tool which is demonstrated to visualize the natural language processing task of language modelling.

description: Leitgeschiebezählungen wurden in vier Tills in Kliffprofilen auf der Insel Møn, Dänemark durchgeführt. Die Resultate sind als „Kreis-Karten“ abgebildet. Die in dieser Arbeit vorgelegten Till-Einheiten sind distinkt verschieden. Diese Unterschiede konnten bislang mit anderen Methoden nicht entsprechend klar gezeigt werden, so z.B. durch die Berechnung des theoretischen Geschiebezentrums (TGZ). Deshalb wurden die Møn-Zählungen als Ausgangspunkt für eine Methodenkritik verwendet, mit Hinweisen auf bisher unbeachtet gebliebene Information. Von lokalem Interesse ist, dass die „baltische“ Provenienz des Klintholm Tills revidiert werden sollte, und dass die von Aber (1979) vorgelegte und auf Feinkies basierte Interpretation von Till-Einheiten im Hvideklint-Profil abgelehnt werden muss.

description: The Gardner length scale $ξ$ is the correlation length in the vicinity of the Gardner transition, which is an avoided transition in glasses where the phase space of the glassy phase fractures into smaller sub-basins on experimental time scales. We argue that $ξ$ grows like $ \sim \sqrt{B_{\infty}/G_{\infty}}$, where $B_{\infty}$ is the bulk modulus and $G_{\infty}$ is the shear modulus, both measured in the high-frequency limit of the glassy state. We suggest that $ξ$ might be inferred from stress-stress correlation functions, which is more practical for experimental investigation than studying two copies of the system, which can only be done in numerical simulations. Our arguments are illustrated by explicit calculations for a system of disks moving in a narrow channel, which is solved exactly by transfer matrix techniques.

description: BackgroundThere is a lack of registry studies about transradial access (TRA) outcomes. This prospective registry evaluated the TRA and procedure outcomes of visceral embolizations performed via TRA with 30-day follow-up.Material & methodsProspective, multicenter registry included uterine fibroids (UFE), prostate artery (PAE), liver tumors (LT), and other hypervascular tumors (OHT) embolization performed in six US hospitals. Between February 2020 and January 2022, 99 patients underwent one radial artery visceral intervention (RAVI); 70 had UFE (70.7%), 16 PAE (16.2%), 7 LT (7.1%), and 6 OHT (6.1%). The mean age was 50.1 (±11.1) years, and 74/99 (74.7%) were females. The primary safety endpoints included hand ischemia, stroke, and death. Procedural success was defined as completing the intended procedure via radial artery (RA) access. Technical success was defined as the successful delivery of HydroPearl™ microspheres and complete embolization of the target vessel.ResultsProcedural and technical successes were 100% and 97%, respectively. There was no stroke, hand ischemia, radial-to-femoral conversion, access-related serious adverse events, or clinically evident radial artery occlusion at 30 days. There were two deaths: one respiratory failure and one progression of liver disease. Minor RA-related adverse event included arterial spasm, hematoma, and post-procedure discomfort.ConclusionThis prospective, multicenter, open-label registry confirmed the high safety profile and effectiveness of radial access in UFE, PAE, LT, and OHT embolization procedures without stroke, hand ischemia, or access-related serious adverse events at 30-day follow-up.

description: A lavoura de arroz gaúcha se destaca no âmbito nacional e há muitos anos tem incrementado sua produtividade, promovendo desenvolvimento econômico e social. Várias mudanças produtivas, comerciais e governamentais que ocorreram ao longo das últimas décadas modificaram os preços agrícolas do produto, alterando a rentabilidade da atividade. Assim, o objetivo do presente trabalho é analisar o comportamento dos preços reais pagos ao produtor de arroz do Rio Grande do Sul de 1973 a 2005, observando as características de tendência, sazonalidade e ciclos, além de analisar a evolução da margem de comercialização do produto. O estudo foi realizado com base em duas séries históricas de preços nominais mensais de arroz no Rio Grande do Sul, a de preços pagos ao produtor e a de preços pagos pelo consumidor final, obtidas junto à EMATER/RS e ao IEPE/UFRGS respectivamente. Os preços nominais foram deflacionados para dezembro de 2005 pelo IGP-DI da Fundação Getulio Vargas. Calculou-se também os Índices de Preço ao consumidor e ao produtor. Para a análise dos componentes ciclo e sazonalidade, calculou-se os Índices de Estacionalidade para cada década e os relativos de ciclo de cada período. Por fim, calculou-se a Margem de Comercialização do produto. Concluiu-se, no estudo, que os preços pagos ao produtor têm apresentado uma persistente tendência de queda desde a década de 70, configurando uma taxa média de crescimento de –3,53% ao ano. Observou-se, também, que o mercado de arroz apresenta ciclos de preço mais ou menos regulares, nunca ultrapassando três anos de duração, e que a variação estacional dos preços pagos ao produtor aumentou a partir da década de 90. Os índices de preços ao produtor e ao consumidor mostraram que no longo prazo estes preços tiveram o mesmo comportamento, com pequenos intervalos de descolamento, o que fez com que as margens de comercialização situassem-se entre 60% e 72%, sem apresentar tendência visível no longo prazo.

description: Mit dem Ziel eine Gliederung der mittel- und spätpleistozänen Grossvergletscherungen in der Nordschweiz zu erarbeiten, werden sedimentologische und morphologische Befunde aus sieben Schlüsselregionen erläutert und interpretiert. Die Untersuchungen umfassen den Zeitraum nach der Ablagerung der Tieferen Deckenschotter längs des Hochrheins und einer darauf folgenden vom Bodenseeraum ausgehenden markanten Ausräumung. Für diese Periode lassen sich vier Grossglaziale nachweisen. Sie werden gemäss den Frontlagen der Vergletscherungen im Rhein-Aare-Reuss-System als Möhlin-, Habsburg-, Koblenz- und Birrfeld-Glazial bezeichnet. Erfassbar sind auch die dazwischen eingeschobenen Interglaziale Holstein, Meikirch und Eem. Die vier Vorlandvergletscherungen weisen folgende Merkmale auf: - Möhlin-Eiszeit: Grösste Vergletscherung des nördlichen Alpenvorlandes im Anschluss an die grosse Ausräumungsphase. Eisüberflutung des östlichen Juras und der Höhen nördlich des unteren Hochrheins und des Klettgaus. - Habsburg-Eiszeit: Ausmass etwa wie die jüngste Vergletscherung (Birrfeld). Extern der Gletscherzungen Schüttung der mächtigen Hochterrassen-Schotterstränge. Intern in den tiefen Becken hoch liegende Seen. - Koblenz-Eiszeit (Beringen sensu GRAF 2009b): Zweitgrösste Vorlandvergletscherung, bisher oft als grösste Eiszeit („Riss“) angesprochen. Greift zwischen Koblenz und Schaffhausen über den heutigen Hochrhein hinaus. - Birrfeld-Eiszeit: Letzte und jüngste Eiszeit, bisher als „Würm“ angesprochen. Überfährt die meisten tiefen Becken und baut markante Endmoränenkränze auf. Extern werden die Schotter des Niederterrassensystems abgelagert. Die Chronostratigraphie der Nordschweiz basiert auf Zeitmarken für die Interglaziale Eem und Holstein aus Norddeutschland sowie Meikirch aus der Schweiz. Die vier Glaziale verteilen sich demgemäss wie folgt über den Untersuchungszeitraum: Möhlin +350 ka BP (MIS 10), Habsburg +250 ka BP (MIS 8), Koblenz +150 ka BP (MIS 6), Birrfeld 30-15 ka BP (MIS 2). Ein Vergleich mit der Quartärgliederung gemäss der Stratigraphischen Tabelle von Deutschland 2002 (LITT et al. 2005) zeigt, dass für drei Glaziale Korrelationen möglich sind: Möhlin mit Elster/Mindel, Koblenz mit Saale/Riss und Birrfeld mit Weichsel/Würm.

description: A multi-component system is presented in which the actuation of a copper-loaded nanoswitch by zinc(II) ions as an external trigger and the thereby prompted release of copper(I) ions allows self-assembly of 11 parts resulting in the formation of a three-component supramolecular prism. Using the same protocol, a three-component rectangle was made from eight parts. Disassembly of the aggregates was accomplished by selective removal of zinc(II) ions using hexacyclen. In sum, the reversible assembly and disassembly of supramolecular aggregates was controlled in a multi-component mixture through intermolecular communication using a second messenger.

description: Abstract: Metro is a type of public transportation system with high capacity, which is mostly established in urban areas. Unlike a bus or a tram, the subway is a type of electric rail system that works on its special tracks, and pedestrians or any other vehicles do not have access to this track, and it mostly moves in tunnels or elevated non-level rails. Modern metro services are usually provided by electric self-propelled trains that run on railway tracks, although there are also some trains with rubber wheels or magnetic levitation. Metro stations are usually higher than the train tracks and do not have any stairs to the train. These platforms usually have a space compared to the train, so to reduce this space between the platform and the train, custom trains need to be built. As the second largest religious city in the world, Mashhad welcomes more than 22 million travelers every year. The comprehensive transport studies of Mashhad required 4 metro lines. Line 1 has been constructed and operated using the slow method, and Line 2 is in the operation stage. Line 2 of the Mashhad metro runs north-south and is 14 kilometers long, with a diameter of 9.43 meters, and passes through important parts of the city. This research, using a quantitative methodology and using a model tunnel, and a seismograph, has recorded the incoming earthquakes and predicted the resilience of this subway line in the city of Mashhad in 2024. For all the tunnel tests, the bending moment and deformations of the tunnel increase with the increase of the maximum base acceleration, but the location of the minimum and maximum values of the moment remain constant. The largest bending moment values appear in the middle of the crown and shoulder of circular tunnels. For the acceleration of A=0.27g, with the increase of the applied frequency to the system, the bending moment is constant or slightly decreases, but for A=0.43g, the maximum moment decreases strongly with the increase of the frequency.

description: We argue that the long-standing issues of neutrino mass and dark matter can be manifestly solved in a dark gauge symmetry $U(1)_D$ that transforms nontrivially only for three right-handed neutrinos $ν_{1,2,3R}$ -- the counterparts of known left-handed neutrinos. This theory assigns $ν_{1,2,3R}$ dark charge to be $D=0$, $-1$, and $+1$, respectively, in order for anomaly cancelation. Additionally, it imposes an inert Higgs doublet $η$ and two Higgs singlets $ξ,ϕ$ with dark charge $D=+1$, $-1$, and $+2$, respectively. That said, the dark symmetry is broken by $ϕ$ (by two units) down to a dark parity $P_D=(-1)^D$, for which $ν_{2,3R}$ and $η,ξ$ are odd, whereas all other fields are even due to $D=0$. The lightest of these odd fields is stabilized by $P_D$, responsible for dark matter. Neutrino masses are generated by a scotoseesaw scheme, in which the seesaw part is mediated by $ν_{1R}$, while the scotogenic part is mediated by $ν_{2,3R}$, for which the hierarchy of atmospheric and solar neutrino mass splittings is explained.

description: Layered Co oxide NaxCoO2.yH2O with a superconducting transition temperature Tc =4.5 K has been studied by 59Co NQR. The nuclear spin relaxation rate 1/59T1 is nearly proportional to temperature T in the normal state. In the superconducting state, it exhibits the coherence peak and decreases with decreasing T below ~0.8Tc. Detailed comparison of the 1/T1T values and the magnetic susceptibilities between NaxCoO2.yH2O and NaxCoO2 implies that the metallic state of the former system is closer to a ferromagnetic phase than that of the latter. These experimental results impose a restriction on the mechanism of the superconductivity.

description: Work extraction is one of the most central processes in quantum thermodynamics. However, the prior analysis of optimal extractable work has been restricted to a limited operational scenario where complete information about the initial state is given. Here, we introduce a general framework of black box work extraction, which addresses the inaccessibility of information on the initial state. We show that the optimal extractable work in the black box setting is completely characterized by the performance of a composite hypothesis testing task, a fundamental problem in information theory. We employ this general relation to reduce the asymptotic black box work extraction to the quantum Stein's lemma in composite hypothesis testing, allowing us to provide their exact characterization in terms of the Helmholtz free energy. We also show a new quantum Stein's lemma motivated in this physical setting, where a composite hypothesis contains a certain correlation. Our work exhibits the importance of information about the initial state and gives a new interpretation of the quantities in the composite quantum hypothesis testing, encouraging the interplay between the physical settings and the information theory.

description: 10Be-Oberflächenaltersdatierungen von Moränenblöcken der Würm-Maximalvergletscherung und der Deglaziationzeit ergaben in zwei verschiedenen Regionen Süddeutschlands unterschiedliche Altersverteilungen trotz gleicher klimatischer Randbedingungen. Im Bayerischen Wald zeigen die Moränenalter eines kleinen Talgletschers eine präzise und konsistente spätwürmzeitliche Chronostratigraphie. Oberflächenexpositionsalter von Moränen des Isar-Loisach und Inngletschers in den Ostalpen weisen auf eine hochwürmzeitliche Moränenablagerung deutlich vor 18.0±1.9 ka und einer anschliessenden Moränenstabilisierung hin. Beide glaziale Systeme (Mittelgebirgs-Talgletscher und alpines Eisstromnetz) erreichten ihre maximale Ausdehnung im Spätwürm (MIS 2). Trotz der weitgehenden Übereinstimmung war ihre Reaktionszeit auf Klimafluktuationen sehr unterschiedlich: der kleine Talgletscher reagierte empfindlicher auf klimatische Änderungen als das alpine Eisstromnetz. Ein synchrones Verhalten zeigten die Gletscher im Bayerischen Wald sowie in den Ostalpen erst im Spätglazial um 16–15 ka (H 1), als in beiden Gebieten Talgletscher existierten. Die unterschiedlichen Altersverteilungen der spätwürmzeitlichen Chronologien in den beiden Würmgletscher-Endmoränengebieten werden mit Unterschieden der Eisdynamik und der geomorphologischen Prozesse bei der Moränenstabilisierung sowie mit Phasen intensiver Hangprozesse infolge periglazialer Aktivität und Toteis-Tauens erklärt. Die Ergebnisse sind für Probennahmestrategien und Dateninterpretation von Moränen-Oberflächenaltern von großer Bedeutung.

description: Dengue viruses (DENV1–4) are the most prevalent arboviruses in humans and a major public health concern. Understanding immune mechanisms that modulate DENV infection outcome is critical for vaccine development. Neutralizing antibodies (nAbs) are an essential component of the protective immune response, yet their measurement often relies on a single cellular substrate and partially mature virions, which does not capture the full breadth of neutralizing activity and may lead to biased estimations of nAb potency. Here, we analyze 125 samples collected after one or more DENV infections but prior to subsequent symptomatic or inapparent DENV1, DENV2, or DENV3 infections from a long-standing pediatric cohort study in Nicaragua. By assessing nAb responses using Vero cells with or without DC-SIGN and with mature or partially mature virions, we find that nAb potency and the protective NT50 cutoff are greatly influenced by cell substrate and virion maturation state. Additionally, the correlation between nAb titer and protection from disease depends on prior infection history and infecting serotype. Finally, we uncover variations in nAb composition that contribute to protection from symptomatic infection differently after primary and secondary prior infection. These findings have important implications for identifying antibody correlates of protection for vaccines and natural infections.

description: We analyze the electronic structure of group II-VI semiconductors obtained within LMTO approach in order to arrive at a realistic and minimal tight binding model, parameterized to provide an accurate description of both valence and conduction bands. It is shown that a nearest-neighbor $sp^3d^5$ model is fairly sufficient to describe to a large extent the electronic structure of these systems over a wide energy range, obviating the use of any fictitious $s^*$ orbital. The obtained hopping parameters obey the universal scaling law proposed by Harrison, ensuring transferability to other systems. Furthermore, we show that certain subtle features in the bonding of these compounds require the inclusion of anion-anion interactions in addition to the nearest-neighbor cation-anion interactions.

Dazu werden zwei Sedimentbohrkerne jeweils aus einem Maarsee und einem Trockenenmaar (Eifel, Deutschland) untersucht. Beide Kerne umfassen das letzte Glazial, einschließlich des MIS-3, des LGM und MIS-2, Transition I als auch das Holozän. Die energiedispersive RFA-Messungen der Eagle III μXRF wird direkt an Harz imprägnierten Proben angewendet. Diese sogenannten Tränklinge bilden die Grundlage für die Herstellung von petrographischen Dünnschliffen und somit können die Messergebnisse direkt mit einer Mikrofaziesanalyse verglichen werden. Anhand eines Sedimentkerns wird gezeigt, dass eine Quantifizierung der μXRF-Ergebnisse mittels der undamentalparametermethode geeignete ist. Eine Überprüfung der Ergebnisse findet dabei mit wellenlängen-dispersiven RFA-Messungen an diskreten Proben statt. Die Ergebnisse zeigen, dass sich jedes einzelne Maar in der lithologischen Zusammensetzung und damit auch geochemisch unterscheidet. Deshalb wird auf die grundlegenden Prozesse der Elementdeposition in die Seen eingegangen, die mit der Ablagerung von Sedimenten, der Variabilität der chemischen Verwitterung oder der Wasserzirkulation in Zusammenhang stehen. Mittels Hauptkomponentenanalysen standardisierter Variablen ist darüber hinaus die objektive Ableitung eines äolischen Sedimentsignals möglich. Es wird gezeigt, dass dieser Ansatz verlässliche Ergebnisse für alle untersuchten Zeitabschnitte liefert, solange für die Interpretation weitere Kenntnisse über die Lithologie und Paläoökologie zur Verfügung stehen. Das auffälligste Element zur Charakterisierung von Staub ist in beiden untersuchten Kernen Kalzium. Die höchsten Werte (>5 Gew.-%) werden während vollglazialer Bedingungen erreicht. Kalzium hat einen wesentlichen Einfluss auf den Staubfaktor der Hauptkomponentenanalyse. Eine zusätzliche Kombination der Kalziumgehalte mit dem Staubfaktor der Hauptkomponentenanalyse sowie Grauwertmessungen verbessert den Nachweis äolischen Staubs in laminierten Seesedimenten zusätzlich. In beiden Kernen konnten Sedimente mit erhöhten Staubkonzentrationen geochemisch nachgewiesen werden: Während des MIS-3 sind das vor allem das größte Heinrich-Ereignis H4 sowie der Anstieg des atmosphärischen Staubgehalts während der Wiedervereisung der Inlandsgletscher. Weiterhin ist das gesamte MIS-2 einschließlich LGM und der Jüngeren Dryas von starker Staubdeposition charakterisiert. Eine erhöhte Staubkonzentration ist ebenfalls ab dem Subboreal nachgewiesen und wird als anthropogene Aktivität gedeutet.

description: We demonstrate that an electric field could activate the three low-energy eigenmodes of the Neel-type skyrmion lattice via the electrically induced Dzyaloshinskii-Moriya interaction. In particular, we predict that the relative intensity of the clockwise rotation mode against the counter-clockwise rotation mode is significantly enhanced for the electrical activation in comparison with the magnetic activation. We also discover that the electrically and magnetically active modes obey unique selection rules. These findings promise a fresh pathway towards energy-efficient electrical manipulation of skyrmion excitations for future skyrmion-based magnonics.

description: In this work, we report a lattice calculation of $x$-dependent valence pion generalized parton distributions (GPDs) at zero skewness with multiple values of the momentum transfer $-t$. The calculations are based on an $N_f=2+1$ gauge ensemble of highly improved staggered quarks with Wilson-Clover valence fermion. The lattice spacing is 0.04 fm, and the pion valence mass is tuned to be 300 MeV. We determine the Lorentz-invariant amplitudes of the quasi-GPD matrix elements for both symmetric and asymmetric momenta transfers with similar values and show the equivalence of both frames. Then, focusing on the asymmetric frame, we utilize a hybrid scheme to renormalize the quasi-GPD matrix elements obtained from the lattice calculations. After the Fourier transforms, the quasi-GPDs are then matched to the light-cone GPDs within the framework of large momentum effective theory with improved matching, including the next-to-next-to-leading order perturbative corrections, and leading renormalon and renormalization group resummations. We also present the 3-dimensional image of the pion in impact-parameter space through the Fourier transform of the momentum transfer $-t$.

description: We evaluate the on shell form factors of the electron for arbitrary momentum transfer and finite electron mass, at two loops in QED, by integrating the corresponding dispersion relations, which involve the imaginary parts known since a long time. The infrared divergences are parameterized in terms of a fictitious small photon mass. The result is expressed in terms of Harmonic Polylogarithms of maximum weight 4. The expansions for small and large momentum transfer are also given

description: Eine revidierte Vergletscherungsgeschichte des nördlichen Vorlandes der Schweizer Alpen wird vorgestellt, basierend auf Feldbefunden und chronologischen Daten von verschiedenen Schlüssellokalitäten und Regionen. Die ältesten quartären Sedimente der Schweiz sind mehrphasige Kiese, in die Till und Hochflutsedimente eingeschaltet sind (’Deckenschotter’). Bedeutende Unterschiede im Basisniveau der Schotterablagerungen erlauben die Unterscheidung zweier komplex augebauter Einheiten (’Höhere Deckenschotter’, ’Tiefere Deckenschotter’), die durch eine Phase bedeutender Einschneidung getrennt sind. Säugetierreste stellen die ältere Einheit (‘Höhere Deckenschotter’) in die Zone MN 17 (2.6–1.8 Ma). Jeder der Komplexe enthält Belege für zumindest zwei, möglicherweise sogar bis zu vier eigenständige Eiszeiten, woraus sich in Summe bis zu acht frühpleistozäne Vergletscherungen des Schweizer Alpenvorlands ergeben. Die frühpleistozänen Deckenschotter sind von mittelpleistozänen Ablagerungen durch eine Zeit bedeutender Erosion getrennt, die wahrscheinlich durch tektonische Bewegungen und/oder eine Umleitung des Alpenrheins verursacht wurde (Mittelpleistozäne Reorganisation – MPR). Das Mittel-/Spätpleistozän beinhaltet vier oder fünf Eiszeiten, die nach ihren Schlüsselregionen als Möhlin-, Habsburg-, Hagenholz- (unsicher, unzureichend belegt), Beringen- und Birrfeld-Eiszeit benannt sind. Die Möhlin-Eiszeit repräsentiert die grösste Vergletscherung des Schweizer Alpenvorlandes, während die Beringen-Eiszeit von nur wenig geringerer Ausdehnung war. Der letzte Glazialzyklus (Birrfeld-Eiszeit) umfasst wahrscheinlich drei eigenständige Gletschervorstösse, die auf ca. 105 ka, 65 ka und 25 ka datiert wurden. Für den letzten Eisvorstoss wird eine detaillierte Radiokohlenstoffchronologie für den Eisaufbau und das Abschmelzen präsentiert.

citizen science reseach areas

description: Recent studies and experience indicate that environmental sciences are a predominant research topic in the citizen science landscape. However, many of these analyses associate each single project only with one main research area. This neglects the multi-disciplinary nature of many projects, which is also reflected in the diversity of participant backgrounds, project consortia and the practical orientation of projects. Catlin-Groves (2012) points out a paradigm shift that results in “a new synthesis of disciplinary areas”. To address this issue, we follow an analytical approach to assess research areas based on public project descriptions of 218 Zooniverse projects. In contrast to counting only the primary field of research, this approach respects this multi-disciplinary nature of citizen science and aggregates multiple research areas, which draws a different picture of the citizen science landscape. How to interpret this data  We analysed 218 project descriptions using text-analytics based on explicit semantic analysis (ESA). In contrast to prior research, we can assign multiple research areas to each project. The research areas are mapped using the web of science taxonomy, which consists of categories with several research areas in each category. Figure 1 shows the distribution of the top 20 research areas across all projects. Apart from “Biodiversity & Conservation”, “Remote Sensing” is a frequent area, which is plausible because many environmental projects also advance research and development in this area. Figure 2 presents the distribution over the five research categories. References: Catlin-Groves, C. L. (2012). The citizen science landscape: from volunteers to citizen sensors and beyond.

description: The title compound is investigated by specific heat measurements in the normal and superconducting state supplemented by upper critical field transport, susceptibility and magnetization measurements. From a detailed analysis including also full potential electronic structure calculations for the Fermi surface sheets, Fermi velocities and partial densities of states the presence of both strong electron-phonon interactions and considerable pair-breaking has been revealed. The specific heat and the upper critical field data can be described to first approximation by an effective single band model close to the clean limit derived from a strongly coupled predominant hole subsystem with small Fermi velocities. However, in order to account also for Hall-conductivity and thermopower data in the literature, an effective general two-band model is proposed. This two-band model provides a flexible enough frame to describe consistently all available data within a scenario of phonon mediated s-wave superconductivity somewhat suppressed by sizeable electron-paramagnon or electron-electron Coulomb interaction. For quantitative details the relevance of soft phonons and of a van Hove type singularity in the electronic density of states near the Fermi energy is suggested.

description: We present a new idea that allows us to detect gravitational waves without being disturbed by any kind of displacement noise, based on the fact that gravitational waves and test-mass motions affect the propagations of light differently. We demonstrate this idea by analyzing a simple toy model consisting three equally-separated objects on a line. By taking a certain combination of light travel times between these objects, we construct an observable free from the displacement of each object which has a reasonable sensitivity to gravitational waves.

description: Realistic image restoration is a crucial task in computer vision, and diffusion-based models for image restoration have garnered significant attention due to their ability to produce realistic results. Restoration can be seen as a controllable generation conditioning on priors. However, due to the severity of image degradation, existing diffusion-based restoration methods cannot fully exploit priors from low-quality images and still have many challenges in perceptual quality, semantic fidelity, and structure accuracy. Based on the challenges, we introduce a novel image restoration method, SSP-IR. Our approach aims to fully exploit semantic and structure priors from low-quality images to guide the diffusion model in generating semantically faithful and structurally accurate natural restoration results. Specifically, we integrate the visual comprehension capabilities of Multimodal Large Language Models (explicit) and the visual representations of the original image (implicit) to acquire accurate semantic prior. To extract degradation-independent structure prior, we introduce a Processor with RGB and FFT constraints to extract structure prior from the low-quality images, guiding the diffusion model and preventing the generation of unreasonable artifacts. Lastly, we employ a multi-level attention mechanism to integrate the acquired semantic and structure priors. The qualitative and quantitative results demonstrate that our method outperforms other state-of-the-art methods overall on both synthetic and real-world datasets.
