Measurement of the eta->3pi0 Dalitz Plot Distribution with the WASA Detector at COSY
Creators: name: COSY Collaboration
Publisher: name: arXiv
Year: 2008
Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: In the first production run of the WASA experiment at COSY, the eta decay into three neutral pions was measured in proton-proton interactions at a proton beam kinetic energy of 1.4 GeV. The Dalitz plot of the three pions was studied using 1.2e5 fully reconstructed events, and the quadratic slope parameter alpha was determined to be -0.027+/-0.008(stat)+/-0.005(syst). The result is consistent with previous measurements and further corroborates the importance of pion-pion final state interactions.

description: We consider composition and division algebras over the real numbers: We note two rôles for the group $G_{2}$: as automorphism group of the octonions and as the isotropy group of a generic 3-form in 7 dimensions. We show why they are equivalent, by means of a regular metric. We express in some diagrams the relation between some pertinent groups, most of them related to the octonions. Some applications to physics are also discussed.

description: A bright feature 80 pc away from the core in the powerful jet of M87 shows highly unusual properties. Earlier radio, optical and X-ray observations have shown that this feature, labeled HST-1, is superluminal, and is possibly connected with the TeV flare detected by HESS in 2005. It has been claimed that this feature might have a blazar nature, due to these properties. To examine the possible blazar-like nature of HST-1, we analyzed lambda 2 cm VLBA archival data from dedicated full-track observations and the 2 cm survey/MOJAVE VLBI monitoring programs obtained between 2000 and 2009. Applying VLBI wide-field imaging techniques, the HST-1 region was imaged at milliarcsecond resolution. Here we present the first 2 cm VLBI detection of this feature in observations from early 2003 to early 2007, and analyze its evolution over this time. Using the detections of HST-1, we find that the projected apparent speed is 0.61 +/- 0.31 c. A comparison of the VLA and VLBA flux densities of this feature indicate that is mostly resolved on molliarcsecond scales. This feature is optically thin between lambda 2 cm and lambda 20 cm. We do not find evidence of a blazar nature for HST-1.

description: Some of the high Tc iron pnictides contain magnetic rare-earth elements, raising the question of how the existence and tunability of a d-electron antiferromagnetic order influences the heavy fermion behavior of the f-moments. With CeOFeP and CeOFeAs in mind as prototypes, we derive an extended Anderson lattice model appropriate for these quaternary systems. We show that the Kondo screening of the f-moments are efficiently suppressed by the d-electron ordering. We also argue that, inside the d-electron ordered state (as in CeOFeAs), the f-moments provide a rare realization of a quantum frustrated magnet with competing J1-J2-J3 interactions in an effective square lattice. Implications for the heavy fermion physics in broader contexts are also discussed.

description: The relationship between the black hole mass and velocity dispersion indicated with [O III] line width is investigated for a sample of 87 flat-spectrum radio quasars (FSRQs) selected from SDSS DR3 quasar catalogue. We found the M_bh - sigma_[O III] relation is deviated from Tremaine et al. relation for nearby inactive galaxies, with a larger black hole mass at given velocity dispersion. There is no strong evidence of cosmology evolution in M_bh - sigma_[O III] relation up to z~0.8. A significant correlation between the [O III] luminosity and Broad Line Region (BLR) luminosity is found. When transferring the [O III] luminosity to Narrow Line Region (NLR) luminosity, the BLR luminosity is, on average, larger than NLR one by about one order of magnitude. We found a strong correlation between the synchrotron peak luminosity and NLR luminosity, which implies a tight relation between the jet physics and accretion process.

description: V2491 Cygni (Nova Cygni 2008 No.2) was detected as a transient supersoft X-ray source with the Swift XRT as early as 40 days after the outburst, suggesting a very massive white dwarf (WD) close to the Chandrasekhar limit. We present a unified model of near infrared, optical, and X-ray light curves for V2491 Cyg, and have estimated, from our best-fit model, the WD mass to be 1.3 \pm 0.02 M_\sun with an assumed chemical composition of the envelope, X=0.20, Y= 0.48, X_{CNO} =0.20, X_{Ne} =0.10, and Z = 0.02 by mass weight. We strongly recommend detailed composition analysis of the ejecta because some enrichment of the WD matter suggests that the WD mass does not increase like in RS Oph, which is a candidate of Type Ia supernova progenitors. V2491 Cyg shows a peculiar secondary maximum in the optical light curve as well as V1493 Aql and V2362 Cyg. Introducing magnetic activity as an adding energy source to nuclear burning, we propose a physical mechanism of the secondary maxima.

'Mu-Tau' symmetry, tribimaximal mixing and four zero neutrino Yukawa textures

description: Within the type-I seesaw framework with three heavy right chiral neutrinos and in the basis where the latter and the charged leptons are mass diagonal, a near `mu-tau' symmetry in the neutrino sector is strongly suggested by the neutrino oscillation data. There is further evidence for a close to the tribimaximal mixing pattern which subsumes `mu-tau' symmetry. On the other hand, the assumption of a (maximally allowed) four zero texture in the Yukawa coupling matrix Y_nu in the same basis leads to a highly constrained and predictive theoretical scheme. We show that the requirement of an exact `mu-tau' symmetry, coupled with observational constraints, reduces the `seventy two' allowed textures in such a `Y_nu' to 'only four' corresponding to just two different forms of the light neutrino mass matrix `m_nu'. The effect of each of these on measurable quantities can be described, apart from an overall factor of the neutrino mass scale, in terms of two real parameters and a phase angle all of which are within very constrained ranges. The additional input of a tribimaximal mixing reduces these three parameters to `only one' with a very nearly fixed value. Implications for both flavored and unflavored leptogenesis as well as radiative lepton flavor violating decays are discussed. We also investigate the stability of these conclusions under small deviations due to renormalization group running from a high scale where the four zero texture as well as `mu-tau' symmetry or the tribimaximal mixing pattern are imposed.

description: The main objective of this thesis is to evaluate the thermal and mechanical behaviour of intumescent coatings (also known as reactive fire protection materials) that are used to protect steel structures from a fire exposure due to natural fires. As the intumescence process of currently available coatings deemed to be highly dependent on the heating regime, comprehensive experimental investigations are performed to understand the correlation between the heating as well as the cooling regime and the thermomechanical performance of intumescent coatings. Due to differences in sensitivity, a solvent-borne and a waterborne intumescent coating are investigated by, among others, evaluating their insulation efficiency. Based on the experimental data, a thermomechanical material model is developed. This material model enables two- and three-dimensional finite element simulations of the intumescent coatings applied on steel structures. As natural fires can show arbitrary regimes characterised by various heating and cooling rates, the material model is formulated universally by taking the heating and cooling rate-dependent behaviour of the intumescent coatings into account. Additionally to the finite element modelling, a MATLAB-based calculation approach is developed, aiming to reduce the computational effort and, thus, providing a design procedure for the dry film thickness of intumescent coatings for any desired fire exposure that is covered by the examined parameter range. As no other approach exists yet, this is the first scientifically-based method for the determination of the required dry film thickness of intumescent coatings to protect steel structures when being exposed to natural fires.

description: Сердечно-сосудистые и онкологические заболевания являются двумя ведущими причинами смертности во всем мире. Несмотря на то, что эти заболевания протекают независимо, им свойственен ряд общих факторов риска. Несмотря на миллионы пациентов, выживших после злокачественных опухолей, частота развития ишемической болезни у онкологических пациентов продолжает расти. Для химиотерапии и лучевой терапии также характерны кардиотоксичность и ускорение развития атеросклероза. Вследствие этого, лечение острого коронарного синдрома (ОКС) у этой категории онкологических больных представляет собой достаточно трудную задачу, а установленных стратегий лечения ОКС у пациентов с онкологическими заболеваниями имеется весьма немного. Тромбоцитопения у онкологических пациентов с ОКС усложняет обычную тактику при ОКС, включающую в себя инвазивное вмешательство, двойную антитромбоцитарную терапию и установку стента. Было проведено недостаточно рандомизированных исследований этой категории пациентов. Сложность ведения пациентов со злокачественными новообразования, у которых одновременно выявлен ОКС и тромбоцитопения, требует повышенного внимания к выбору клинической тактики. В данном обзоре освещены основные патофизиологические аспекты тромбоцитопении, ассоциированной с онкологическими заболеваниями, а также тактика ведения таких пациентов с ишемической болезнью сердца.
description: Cardiovascular disease and cancer are two of the leading causes of death worldwide. Although these disease processes are separate, they share a number of common risk factors. With millions of cancer survivors, the prevalence of coronary artery disease in cancer patients will continue to increase. Chemotherapy/radiation therapies carry a risk of cardiotoxicity and accelerated atherosclerosis. Hence, management of acute coronary syndrome (ACS) in this subset of cancer patients is challenging. There are limited established management strategies to address the management of ACS in cancer patients. Thrombocytopenia in cancer patients presenting with ACS complicates the management of ACS requiring intervention, dual antiplatelet therapy, and stent placement. Randomized trials are lacking in these patients. The complexity of managing patient with malignancy who is concurrently suffering from ACS and thrombocytopenia requires attention to management of these patients. This review article intends to highlight the pathophysiology of cancer related thrombocytopenia and management of these patients with coronary artery disease.

description: We have investigated the evolution of a pair of interacting planets embedded in a gaseous disc, considering the possibility of the resonant capture of a Super-Earth by a Jupiter mass gas giant. First, we have examined the situation where the Super-Earth is on the internal orbit and the gas giant on the external one. It has been found that the terrestrial planet is scattered from the disc or the gas giant captures the Super-Earth into an interior 3:2 or 4:3 mean-motion resonance. The stability of the latter configurations depends on the initial planet positions and on eccentricity evolution. The behaviour of the system is different if the Super-Earth is the external planet. We have found that instead of being captured in the mean-motion resonance, the terrestrial planet is trapped at the outer edge of the gap opened by the gas giant. This effect prevents the occurrence of the first order mean-motion commensurability. These results are particularly interesting in light of recent exoplanet discoveries and provide predictions of what will become observationally testable in the near future.

description: It is often assumed that if two people work on a failure-detection task one after the other, they will observe more failures than when only one person undertakes the task (4-eyes principle). However, human beings have also been found to exert less effort on tasks that they share responsibility for, a phenomenon called social loafing. In the current research, we assessed the effectiveness of sequential human redundancy in light of possible social loafing. In two laboratory experiments, teams of two participants performed a quality-control task in a blinded and in a nonblinded condition, operationally defined by whether or not evaluations of the first checker were forwarded to the second one. In the blinded condition, no social loafing was found, and a near-perfect overall team performance was observed. In contrast, nonblinded redundancy led to a substantial effort reduction of the second checker. However, despite this social-loafing effect at the second position, even nonblinded redundancy led to an overall safety advantage over a single-checker condition. Our research suggests that social loafing in sequential-human-redundancy work settings can occur but does not necessarily reduce the gains in overall reliability. Blinded processes, however, seem to provoke less social loafing than nonblinded processes. (PsycInfo Database Record (c) 2023 APA, all rights reserved)

description: Using closed-time path two-particle irreducible coarse-grained effective action (CTP 2PI CGEA) techniques, we study the response of an open interacting electronic system to time-dependent external electromagnetic fields. We show that the CTP 2PI CGEA is invariant under a simultaneous gauge transformation of the external field and the full Schwinger-Keldysh propagator, and that this property holds even when the loop expansion of the CTP 2PI CGEA is truncated at arbitrary order. The effective action approach provides a systematic way of calculating the propagator and response functions of the system, via the Schwinger-Dyson equation and the Bethe-Salpeter equations, respectively. We show that, due to the invariance of the CTP 2PI CGEA under external gauge transformations, the response functions calculated from it satisfy the Ward-Takahashi hierarchy, thus warranting the conservation of the electronic current beyond the expectation value level. We also clarify the connection between nonlinear response theory and the WT hierarchy, and discuss an example of an ad hoc approximation that violate it. These findings may be useful in the study of current fluctuations in correlated electronic pumping devices.

description: Community identification is a long-standing challenge in the modern network science, especially for very large scale networks containing millions of nodes. In this paper, we propose a new metric to quantify the structural similarity between subgraphs, based on which an algorithm for community identification is designed. Extensive empirical results on several real networks from disparate fields has demonstrated that the present algorithm can provide the same level of reliability, measure by modularity, while takes much shorter time than the well-known fast algorithm proposed by Clauset, Newman and Moore (CNM). We further propose a hybrid algorithm that can simultaneously enhance modularity and save computational time compared with the CNM algorithm.

By spotlighting the case of the plant geographer Oscar Drude (1852–1933), I argue that the dynamics of botanical mappings were closely linked to a specific milieu of knowledge production: the visual culture of Imperial Germany. The scientific upgrading of maps was stimulated by a prospering commercial cartographical market as well as a widespread practice of mediating between professionals and amateurs via maps in the public sphere. In transferring skills and practices from these “popular” fields of knowledge to scientific domains, botanists like Oscar Drude established maps as an indispensable element of botanical observation. This wholesale dissemination of botanical maps had thus a formative influence on collective perception – the botanist's “period eye” – regarding plant distribution.

description: We explore N=2 chiral bosons in (2,2), (2,0) and (0,2) superspaces. We start with a manifestly covariant (2,2) description in the Ogievetssky-Sokatchev geometric approach and then, by fixing gauges with respect to local Siegel's transformations, obtain previously unknown (2,0) and (0,2) actions, The anomalous N=2 Feigin-Fuchs term in a (2,0) superfield form is presented. We introduce a Liouville representation for the Feigin-Fuchs-term-modified N=0, N=1 and N=2 chiral bosons, thus demonstrating the relevance of these systems to the two-dimensional (super)gravity and non-critical (super)string theories.

description: The recent outbreak of the Ebola virus (EBOV) has marked it as one of the most severe health threats globally. Among various anti-EBOV inhibitors studied, galidesivir (BCX4430) has shown remarkable efficacy. This study aims to identify novel potential anti-EBOV drugs among galidesivir analogs, focusing on the Zaire ebolavirus (Z-EBOV), which exhibits a mortality rate of 90%. We subjected 200 candidate compounds to molecular docking calculations, followed by an evaluation of the bioactivity of the top 25 compounds using the OSIRIS Property Explorer. Initial 50 ns molecular dynamics (MD) simulations were then performed. According to our findings, only six compounds exhibited positive drug scores. We further performed molecular mechanics Poisson-Boltzmann surface area (MM/PBSA) calculations of binding energy over 50 ns, selecting the two top-performing compounds for extended 150 ns MD simulations. CID 117698807 and CID 117712809 showed higher binding stability compared to galidesivir, with ΔGbinding values of −36.7 and −53.4 kcal/mol, respectively. Both compounds demonstrated high stability within the Z-EBOV-V24 active site over the 150 ns MD simulations. Hence, our study proposes CID 117698807 and CID 117712809 as potential anti-Z-EBOV-V24 drug candidates, warranting further investigation. Communicated by Ramaswamy H. Sarma

description: We present an analytical model for electron self-injection in nonlinear, multidimensional plasma wave excited by short laser pulse in the bubble regime or by short electron beam in the blowout regime. In this regimes, which are typical for electron acceleration in the last experiments, the laser radiation pressure or the electron beam charge pushes out background plasma electrons forming a plasma cavity - bubble - with a huge ion charge. The plasma electrons can be trapped in the bubble and accelerated by the plasma wakefields up to very high energies. The model predicts the condition for electron trapping and the trapping cross section in terms of the bubble radius and the bubble velocity. The obtained results are in a good agreement with results of 3D PIC simulations.

On the smooth cross-over transition from the Delta-string to the Y-string three-quark potential

description: We comment on the assertion made by Caselle et al., J. Stat. Mech. 0603, P008 (2006), that the confining (string) potential for three quarks "makes a smooth cross-over transition from the Delta-string to the Y-string configuration at interquark distances of around 0.8 fm". We study the functional dependence of the three-quark confining potentials due to a Y-string, and the Delta-string and show that they have different symmetries, which lead to different constants of the motion (i.e. they belong to different "universality classes" in the parlance of the theory of phase transitions). This means that there is no "smooth cross-over" between the two, when their string tensions are identical, except at the vanishing hyper-radius. We also comment on a certain two-body potential approximation to the Y-string potential.

description: Living cells are continually exposed to environmental signals that vary in time. These signals are detected and processed by biochemical networks, which are often highly stochastic. To understand how cells cope with a fluctuating environment, we therefore have to understand how reliably biochemical networks can transmit time-varying signals. To this end, we must understand both the noise characteristics and the amplification properties of networks. In this manuscript, we use information theory to study how reliably signalling cascades employing autoregulation and feedback can transmit time-varying signals. We calculate the frequency-dependence of the gain-to-noise ratio, which reflects how reliably a network transmits signals at different frequencies. We find that the gain-to-noise ratio may differ qualitatively from the power spectrum of the output, showing that the latter does not directly reflect signaling performance. Moreover, we find that auto-activation and auto-repression increase and decrease the gain-to-noise ratio for all of frequencies, respectively. Positive feedback specifically enhances information transmission at low frequencies, while negative feedback increases signal fidelity at high frequencies. Our analysis not only elucidates the role of autoregulation and feedback in naturally-occurring biological networks, but also reveals design principles that can be used for the reliable transmission of time-varying signals in synthetic gene circuits.

On the BL Lacertae objects/radio quasars and the FRI/II dichotomy

description: In the frame of unification schemes for radio-loud active galactic nuclei (AGNs), FR I radio galaxies are believed to be BL Lacertae (BL Lac) objects with the relativistic jet misaligned to our line of sight, and FR II radio galaxies correspond to misaligned radio quasars. The Ledlow-Owen dividing line for FR I/FR II dichotomy in the optical absolute magnitude of host galaxy-radio luminosity (M_R-L_Rad) plane can be translated to the line in the black hole mass-jet power (M_bh-Q_jet) plane by using two empirical relations: Q_jet-L_Rad and M_bh}-M_R. We use a sample of radio quasars and BL Lac objects with measured black hole masses to explore the relation of the jet power with black hole mass, in which the jet power is estimated from the extended radio emission. It is found that the BL Lac objects are clearly separated from radio quasars by the Ledlow & Owen FR I/II dividing line in the M_bh-Q_jet plane. This strongly supports the unification schemes for FR I/BL Lac object and FR II/radio quasar. We find that the Eddington ratios L_bol/L_Edd of BL Lac objects are systematically lower than those of radio quasars in the sample with a rough division at L_bol/L_Edd 0.01, and the distribution of Eddington ratios of BL Lac objects/quasars exhibits a bimodal nature, which imply that the accretion mode of BL Lac objects may be different from that of radio quasars.

description: In the recent years, the very issue of food waste management has become a global concern and an alarming topic. According to the Food and Agriculture Organization (FAO), one-third of all food produced worldwide goes to waste each year. The amount of food waste which is generated in the common households is very high, with studies and statistics showing that up to 50% of household waste comprises of food items [1]. Because of the disposal of food waste, it contributes significantly to many such environmental phenomena like greenhouse gas emissions and others, which in turn, contributes to climate change which automatically affects us. One solution which can be provided to this problem is to feed the household animals with food waste. In this article we will explore the management of household food waste to be fed to household animals

description: Illegal and (lawful, but) harmful content – most notably hate speech and fake news, but also violent videos, copyright infringement, or child pornography – is a crucial problem on digital platforms like Facebook, YouTube, TikTok and Twitter. The EU’s 2022 Digital Services Act aims at tackling this problem by introducing an updated horizontal framework for all categories of content and activities on intermediary services. This raises several questions. How far do – national and European – free speech guarantees go? If hate speech can be banned to protect the victims’ rights, how can the prohibition of fake news be justified? What is the remaining leeway of the platforms for private content moderation? Who is responsible for fighting and taking down illegal content? How can the victims of de-platforming, content takedowns or shadow banning claim their right to freedom of opinion? Finally, how will these legal responsibilities be enforced? These questions are addressed in the articles of the edited volume, proceeding from the 2022 Annual Conference of the Institute for Digital Law Trier (IRDT).
