description: We compare the noise in interferometric measurements of the Vela pulsar from ground- and space-based antennas with theoretical predictions. The noise depends on both the flux density and the interferometric phase of the source. Because the Vela pulsar is bright and scintillating, these comparisons extend into both the low and high signal-to-noise regimes. Furthermore, our diversity of baselines explores the full range of variation in interferometric phase. We find excellent agreement between theoretical expectations and our estimates of noise among samples within the characteristic scintillation scales. Namely, the noise is drawn from an elliptical Gaussian distribution in the complex plane, centered on the signal. The major axis, aligned with the signal phase, varies quadratically with the signal, while the minor axis, at quadrature, varies with the same linear coefficients. For weak signal, the noise approaches a circular Gaussian distribution. Both the variance and covariance of the noise are also affected by artifacts of digitization and correlation. In particular, we show that gating introduces correlations between nearby spectral channels.

description: Similar to the associated Legendre functions, the differential equation for the associated Bessel functions $B_{l,m}(x)$ is introduced so that its form remains invariant under the transformation $l\rightarrow -l-1$. A Rodrigues formula for the associated Bessel functions as squared integrable solutions in both regions $l<0$ and $l\geq 0$ is presented. The functions with the same $m$ but with different positive and negative values of $l$ are not independent of each other, while the functions with the same $l+m$ ($l-m$) but with different values of $l$ and $m$ are independent of each other. So, all the functions $B_{l,m}(x)$ may be taken into account as the union of the increasing (decreasing) infinite sequences with respect to $l$. It is shown that two new different types of exponential generating functions are attributed to the associated Bessel functions corresponding to these rearranged sequences.
Algebraic probability, classical stochastic processes, and counting statistics

description: We study a connection between the algebraic probability and classical stochastic processes described by master equations. Introducing a definition of a state which has not been used for quantum cases, the classical stochastic processes can be reformulated in terms of the algebraic probability. This reformulation immediately gives the Doi-Peliti formalism, which has been frequently used in nonequilibrium physics. As an application of the reformulation, we give a derivation of basic equations for counting statistics, which plays an important role in nonequilibrium physics.

description: We present measurements of the linear diameter of the emission region of the Vela pulsar at observing wavelength lambda=18 cm. We infer the diameter as a function of pulse phase from the distribution of visibility on the Mopra-Tidbinbilla baseline. As we demonstrate, in the presence of strong scintillation, finite size of the emission region produces a characteristic W-shaped signature in the projection of the visibility distribution onto the real axis. This modification involves heightened probability density near the mean amplitude, decreased probability to either side, and a return to the zero-size distribution beyond. We observe this signature with high statistical significance, as compared with the best-fitting zero-size model, in many regions of pulse phase. We find that the equivalent full width at half maximum of the pulsar's emission region decreases from more than 400 km early in the pulse to near zero at the peak of the pulse, and then increases again to approximately 800 km near the trailing edge. We discuss possible systematic effects, and compare our work with previous results.

description: Per- and polyfluoroalkyl substances (PFAS) pose a major health and environmental problem. Methods are needed to ensure that PFAS are not released into the environment during their use or disposal. Alumina-based catalysts have been used for the abatement of small perfluorocarbons, e.g. tetrafluoromethane and perfluoropropane, emitted during the silicon etching process. Here, an alumina-based catalyst was tested to determine if these catalysts may facilitate the destruction of gas-phase PFAS. The catalyst was challenged with two nonionic surfactants with eight fluorinated carbons, 8:2 fluorotelomer alcohol and N-Ethyl-N-(2-hydroxyethyl)perfluorooctylsulfonamide. The catalyst helped decrease the temperatures needed for the destruction of the parent PFAS relative to a thermal-only treatment. Temperatures of 200 °C were sufficient to destroy the parent PFAS using the catalyst, although a significant number of fluorinated products of incomplete destruction (PIDs) were observed. The PIDs were no longer observed by about 500 °C with catalyst treatment. Alumina-based catalysts are a promising PFAS pollution control technology that could eliminate both perfluorocarbons and longer chain PFAS from gas streams.

description: The fluctuation effect of laser pumping rate on the output noise fluxes of class-A lasers is investigated. The method is based on the role of cavity Langevin force as a fluctuating force in the absence of the atomic population inversion and dipole moment Langevin forces. The temporal fluctuations induced to the phase and amplitude of the cavity electric field and the atomic population inversion are calculated in both below and above threshold states. Our aim is to derive correlation functions for the fluctuating variables of the cavity electric field and the atomic population inversion to determine the noise fluxes emerging from the cavity mirrors and measured by an optical detector and those radiated in the form of spontaneous emission in all spatial directions. We introduce a heuristic conservation relation that connects the noise flux generated by the laser pumping system with those distributed among the laser variables. Finally, the results are confirmed by demonstrating the energy conservation law.

description: Within A Multi-Phase Transport model, we investigate decorrelation of event planes over pseudorapidity and its effect on azimuthal anisotropy measurements in relativistic heavy-ion collisions. The decorrelation increases with increasing η gap between particles used to reconstruct the event planes. The third harmonic event planes are found even anticorrelated between forward and backward rapidities, the source of which may root in the opposite orientation of the collision geometry triangularities. The decorrelation may call into question the anisotropic flow measurements with pseudorapidity gap designed to reduce nonflow contributions, hence the hydrodynamic properties of the quark-gluon plasma extracted from those measurements.

description: The evolution speed in projective Hilbert space is considered for Hermitian Hamiltonians and for non-Hermitian (NH) ones. Based on the Hilbert-Schmidt norm and the spectral norm of a Hamiltonian, resource-related upper bounds on the evolution speed are constructed. These bounds are valid also for NH Hamiltonians and they are illustrated for an optical NH Hamiltonian and for a non-Hermitian $\mathcal{PT}-$symmetric matrix Hamiltonian. Furthermore, the concept of quantum speed efficiency is introduced as measure of the system resources directly spent on the motion in the projective Hilbert space. A recipe for the construction of time-dependent Hamiltonians which ensure 100% speed efficiency is given. Generally these efficient Hamiltonians are NH but there is a Hermitian efficient Hamiltonian as well. Finally, the extremal case of a non-Hermitian non-diagonalizable Hamiltonian with vanishing energy difference is shown to produce a 100% efficient evolution with minimal resources consumption.

description: The slides and code in this repository were developed for Dr. Marco Mesiti's, University of Milan, course titled "Constructing Knowledge Graphs for Advanced Biomedical Applications" (https://homes.di.unimi.it/mesiti/phdcourse2023/ ). Taken from the course website, the course description reads: Knowledge graphs (KGs) can be used as an integration means of heterogenous biomedical concepts and relationships existing in different biological data sources. The presence of various information related to the same topic (e.g. patients, therapies, diseases) can be exploited for tackling many biomedical problems, such as finding new treatments for existing drugs, aiding efforts to diagnose patients, and identifying associations between diseases and biomolecules. In this course, we will discuss the characteristics of knowledge graphs, the languages for their representation and querying, and the systems used for their storage. Then, we will discuss machine learning techniques that can be used to construct and analyze knowledge graphs in different biomedical applications. Finally, we will discuss techniques and examples for the construction of biological knowledge graphs. Slides Overview: The slides (Callahan_Lecture_APR2023.pdf) cover Block 3 of the course, which is focused on the construction of knowledge graphs within the biomedical domain. The lectures provides an introduction to and overview of the Semantic Web and an overview of biomedical knowledge graphs and their applications within the biomedical domain. It also describes three different approaches for constructing knowledge graphs with example GitHub projects and concludes by describing the PheKnowLator Ecosystem, including the technical infrastructure and its biomedical applications. Code Overview: The zipped directory titled kg_course_block3_exercise.zip was created to accompany the slides and provide students with hands-on interactive learning opportunities to better understand knowledge graphs, their use within the Life Sciences, and how they are constructed.

Stochastic Particle Acceleration by Helical Turbulence in Solar Flares

description: Flaring release of magnetic energy in solar corona is only possible if the magnetic field deviates from a potential one. We show that the linear MHD modes excited on top of the non-potential magnetic field possess a nonzero kinetic helicity. Accordingly, this necessarily results in a noticeable kinetic helicity of the turbulence, composed of these linear modes with various scales and random phases, generated at the flare site by the primary energy release, which may be important for many applications. In particular, a nonzero turbulence helicity has a potentially strong effect on the particle acceleration because the helical component of the turbulence induces a mean regular large-scale (DC) electric field capable of directly accelerating the charged particles in addition to the commonly considered stochastic turbulent electric field. In this paper, we derive the kinetic helicity density of the linear MHD modes excited on top of a twisted large-scale magnetic field, estimate the corresponding turbulence helicity and take its effect on stochastic particle acceleration by the turbulence into consideration; in particular, we compare this induced mean electric field with the electron and estimated effective ion Dreicer fields. We have discovered that this, so far missing but highly important, ingredient of the turbulence at the flare site can be responsible for the thermal-to-nonthermal energy partition in flares by controlling the process of particle extraction from the thermal pool and formation of the seed particle population to be then stochastically accelerated to higher energies. In addition, it is naturally consistent with such puzzling flare manifestations as spatial separation of electron and proton emission sites, electron beam formation, and enrichment of the accelerated particle population by $^3He$ and other rare ions.

The analysis aims to better understand the orientations given by these programs to primary school teachers regarding the concept of matter. A lexical analysis coupled with an analysis of the content of the curricula allows us to characterise the institutional intentions with regard to the concept of matter. We uncover some ambiguities that may contribute to the difficulties encountered by school teachers when preparing and implementing inquiry-based science teaching sessions.

Ultrafast spherulitic crystal growth as a stress-induced phenomenon specific of fragile glass-formers

description: We propose a model for the abrupt emergence, below temperatures close to the glass transition, of the ultra-fast (GC) steady mode of spherulitic crystal growth in deeply undercooled liquids. We interpret this phenomenon as controlled by the interplay between the generation of stresses by crystallization and their partial release by flow in the surrounding amorphous visco-elastic matrix. Our model is consistent with both the observed ratios ($\sim10^4$) of fast-to-slow velocities and the fact that fast growth emerges close to the glass transition. It leads us to conclude that the existence of a fast growth regime requires both (i) a high fragility of the glassformer; (ii) the fine sub-structure specific of spherulites. It finally predicts that the transition is hysteretic, thus allowing for an independent experimental test.

Wagnerian Singing and the Limits of Vocal Pedagogy
Creators: name: Parr, Sean M
Publisher: name: Current Musicology
Year: 2020

description: Common perceptions of Wagnerian singing center on its sheer volume, its muscular and heroic tone. This article examines how the last century of Wagnerian singing has been shaped by a school of singing defined not by theories of resonance and phonation, but by the disciplining of the breathing body. I argue that certain ideas of singing technique adapted to and then defined this Wagnerian ideal. My point of departure is an invention known as a “Sbriglia Belt,” a device created by Giovanni Sbriglia, a late nineteenth-century tenor-pedagogue. Sbriglia used the belt in his teaching to help singers press their torsos outward as they sang, thereby achieving greater air pressure and greater volume, a technique that anchors and confines the breath while also empowering the voice, allowing baritones such as Jean de Reszke to push their voices upward, into the heroic tenor domain. A German pedagogue, George Armin, extended this breathing technique further and defined a new school of singing by introducing the idea of “breath damming” in his Das Stauprinzip (1909), a method of breath retention that focuses on increased sub-glottal muscular pressure. This technique became a trademark of the twentieth-century Helden sound. In addition to exploring how breathing affects singing more generally, the essay demonstrates the importance of locating singing in the material, physical body, building on the work of Carolyn Abbate, Karen Henson, and Emily Wilbourne. The essay also adds to the conversation on voice recently brought to the fore by Martha Feldman and Nina Sun Eidsheim. However, instead of focusing on how the voice is either disembodied or located primarily in the laryngeal region, I argue for a recasting of the singer as an entire body fully engaged in creating sound from breath, in a sense re-attaching the body to the voice. In so doing, the essay upsets the conventional notion that singers are defined by and as their voices. As one of the first musicological studies to approach singing as practice from the perspective of breath, I hope to demonstrate that the “work” of the operatic singer involves much more than having “a voice.”

description: We present a series of papers on the year-2012 version of Yonsei Evolutionary Population Synthesis (YEPS) model which is constructed on over 20 years of heritage. This first paper delineates the spectroscopic aspect of integrated light from stellar populations older than 1 Gyr. The standard YEPS is based on the most up-to-date Yonsei-Yale stellar evolutionary tracks and BaSel 3.1 flux libraries, and provides absorption line indices of the Lick/IDS system and high-order Balmer lines for simple stellar populations as functions of stellar parameters, such as metallicity, age and α-element mixture. Special care has been taken to incorporate systematic contribution from horizontal-branch stars which alters the temperature-sensitive Balmer lines significantly, resulting in up to 5 Gyr difference in age estimation of old, metal-poor stellar populations. We also find that the horizontal branches exert an appreciable effect not only on the Balmer lines but also on the metallicity-sensitive lines including the magnesium index. This is critical to explain the intriguing bimodality found in index distributions of globular clusters in massive galaxies and to derive spectroscopic metallicities accurately from various indices. A full set of the spectroscopic and photometric YEPS model data of the entire parameter space is currently downloadable at http://web.yonsei.ac.kr/cosmic/data/YEPS.htm

description: The traditional model of single ownership of all the physical network elements and network layers by mobile network operators is beginning to be challenged. This has been attributed to the rapid and complex technology migration compounded with rigorous regulatory requirements and ever increasing capital expenditures. These trends, combined together with the increasing competition, rapid commoditization of telecommunication equipments and rising separation of network and service provisioning are pushing the operators to adopt multiple strategies, with network infrastructure sharing in the core and radio access networks emerging as a more radical mechanism to substantially and sustainably improve network costs. Through infrastructure sharing, developing countries and other emerging economies can harness the technological, market and regulatory developments that have fostered affordable access to mobile and broadband services. Similarly, the network operators entering or consolidating in the emerging markets can aim for substantial savings on capital and operating expenses. The present paper aims to investigate the current technological solutions and regulatory and the technical-economical dimensions in connection with the sharing of mobile telecommunication networks in emerging countries. We analyze the estimated savings on capital and operating expenses, while assessing the technical constraints, applicability and benefits of the network sharing solutions in an emerging market context.

description: We provide a first derivation of the Bekenstein-Hawking entropy of 3d flat cosmological horizons in terms of the counting of states in a dual field theory. These horizons appear in the shifted-boost orbifold of R^{1,2}, the flat limit of non-extremal rotating BTZ black holes. These 3d geometries carry non-zero charges under the asymptotic symmetry algebra of R^{1,2}, the 3d Bondi-Metzner-Sachs (BMS3) algebra. The dual theory has the symmetries of the 2d Galilean Conformal Algebra, a contraction of two copies of the Virasoro algebra, which is isomorphic to BMS3. We study flat holography as a limit of AdS3/CFT2 to semi-classically compute the density of states in the dual, exactly reproducing the bulk entropy in the limit of large charges. Our flat horizons, remnants of the BTZ inner horizons also satisfy a first law of thermodynamics. We comment on how the dual theory reproduces the bulk first law and how cosmological bulk excitations are matched with boundary quantum numbers.

description: The advancement of mobile technologies and the proliferation of map-based applications have enabled a user to access a wide variety of services that range from information queries to navigation systems. Due to the popularity of map-based applications among the users, the service provider often requires to answer a large number of simultaneous queries. Thus, processing queries efficiently on spatial networks (i.e., road networks) have become an important research area in recent years. In this paper, we focus on path queries that find the shortest path between a source and a destination of the user. In particular, we address the problem of finding the shortest paths for a large number of simultaneous path queries in road networks. Traditional systems that consider one query at a time are not suitable for many applications due to high computational and service costs. These systems cannot guarantee required response time in high load conditions. We propose an efficient group based approach that provides a practical solution with reduced cost. The key concept for our approach is to group queries that share a common travel path and then compute the shortest path for the group. Experimental results show that our approach is on an average ten times faster than the traditional approach in return of sacrificing the accuracy by 0.5% in the worst case, which is acceptable for most of the users.

The Union of Soviet Friendship Societies in the Middle East in the 1970: Pragmatism, Orientalism and Soft Power
Creators: name: Casula, Philipp
Publisher: name: Zenodo
Year: 2022

description: "Arabs are eager to read the works of Tolstoy or of Dostoevsky, but these are not what they are offered. They
 would find at the Soviet Publishing House in Cairo the collected works of Lenin for as little as 30 piastres, but
 this is not what they want". Thus Mohamed Heikal, one of Nasser’s closes advisors, described the Soviet
 ineptness in cultural exchanges. The proposed paper will assess this alleged ineffectiveness to culturally
 outreach to the Arab world by analysing documents of the Union of Soviet Societies for Friendship and Cultural
 Contacts (SSOD) collected at the GARF (R-9576). In contrast to its predecessor VOKS, the SSOD is less
 researched. The material under scrutiny comprises communications between the officials of Soviet Cultural
 Centres in the Middle East and the presidium of the SSOD, reports on events, lists of Soviet literature and
 programmes of film screenings, and minutes of meetings. The selection of documents focuses on the period
 between 1972 and 1979 relating to the activities in North and South Yemen as well as Syria, two countries that
 were particularly close to the USSR. Adopting an Edward Said’s notion of Orientalism, the analysis uncovers
 how Soviet pragmatism (Vasil’ev) is reflected in individual officials' choices, their interactions as well how
 infelicitously they represented the USSR in the Arab World, undermining Soviet "soft power" in the region.

description: Alfven wave dynamics in partially ionized plasmas of the solar atmosphere shows that there is indeed a cut-off wavenumber, i.e. the Alfven waves with wavenumbers higher than the cut-off value are evanescent. The cut-off wavenumber appears in single-fluid magnetohydrodynamic (MHD) approximation but it is absent in a multi-fluid approach. Up to now, an explanation for the existence of the cut-off wavenumber is still missing. The aim of this paper is to point out the reason for the appearance of a cut-off wavenumber in single-fluid MHD. Beginning with three-fluid equations (with electrons, protons and neutral hydrogen atoms), we performed consecutive approximations until we obtained the usual single-fluid description is obtained. We solved the dispersion relation of linear Alfven waves at each step and sought the approximation responsible of the cut-off wavenumber appearance. We have found that neglecting inertial terms significantly reduces the real part of the Alfven frequency although it never becomes zero. Therefore, the cut-off wavenumber does not exist at this stage. However, when the inertial terms together with the Hall term in the induction equation are neglected, the real part of the Alfven frequency becomes zero. The appearance of a cut-off wavenumber, when Alfven waves in partially ionized regions of the solar atmosphere are studied, is the result of neglecting inertial and Hall terms, therefore it has no physical origin.

description: Wehrl used Glauber coherent states to define a map from quantum density matrices to classical phase space densities and conjectured that for Glauber coherent states the mininimum classical entropy would occur for density matrices equal to projectors onto coherent states. This was proved by Lieb in 1978 who also extended the conjecture to Bloch SU(2) spin-coherent states for every angular momentum $J$. This conjecture is proved here. We also recall our 1991 extension of the Wehrl map to a quantum channel from $J$ to $K=J+1/2, J+1, ...$, with $K=\infty$ corresponding to the Wehrl map to classical densities. For each $J$ and $J

description: Citrus Greening Disease or Huanglongbing (HLB) is one of the most devastating diseases of citrus worldwide which is caused by an unculturable prokaryotic α-proteobacterium, Candidatus Liberibacter sp. Once the bacterium enters the tree, it propagates within the phloem producing die-back, yellow shoots, blotchy mottles on leaves, and off-tasting and malformed fruits (Bove, J. M., 2006). There are three (3) reported isolate types of bacterium namely, Candidatus Liberibacter asiaticus, Candidatus Liberibacter americanus, and Candidatus Liberibacter africanus (Li, W., et. al., 2007). In the Philippines, Candidatus Liberibacter asiaticus is most likely the species that is present among HLB-infected trees. With the alarming incidence of the disease and the fact that there is no available product that can combat the pathogen due to its nature, it is necessary to develop a reliable method that would accurately determine the presence of the bacterium for the integration on HLB management.

Roadmap

description: The aim of this delivable is twofold. On the one hand it provides the reader with basic defintions, concepts, and tools for evaluation work on the other hand it provides a definition of the policy evaluation process in PoliRural on general level.
 In the first part of D1.5 first the question ‘What is an Evaluation’ is being discussed followed by a presentation of evaluation objectives and criteria. Then a brief overview on quality criteria for conducting evaluations and functions an evaluation might have is given. Furthermore, the differences between internal and external evaluations are discussed as is monitoring. Additionally, concepts such as participatory evaluation and the multi-method approach are introduced.
 The second part of the deliveable is devoted to a proposal of concrete steps in the evaluation process and the presentation and discussion of the evaluation matrix. These elements form the main pillars of the evaluation concept. Furthermore, a tentative presentation of activities and milestones for the next six months is given as is a simple contingency plan to mitigate risks to the evaluation field work associated to the COVID 19 pandemic. Finally, in the section on conclusions and next steps in particular an outlook on upcoming additional work on evaluation methodology is provided.

Reconstructing the γ-ray Photon Optical Depth of the Universe to z~4 from Multiwavelength Galaxy Survey Data

description: We reconstruct γ-ray opacity of the Universe out to z<3-4 using an extensive library of 342 observed galaxy luminosity function surveys extending to high redshifts. We cover the whole range from UV to mid-IR (0.15-25mic) providing for the first time a robust empirical calculation of the γγ-optical depth out to several TeV. Here, we use the same database as Helgason et al. 2012 where the EBL was reconstructed from luminosity functions out to 4.5mic and was shown to recover observed galaxy counts to high accuracy. We extend our earlier library of LFs to 25mic such that it covers the energy range of pair production with γ-rays 1) in the entire Fermi/LAT energy range, and 2) at higher TeV energies probed by ground-based Cherenkov telescopes. In the absence of significant contributions to the cosmic diffuse background from unknown populations, such as the putative Population III era sources, the Universe appears to be largely transparent to γ-rays at all Fermi/LAT energies out to z~2 whereas becoming opaque to TeV photons already at z<0.2 and reaching τ~10 at z=1. Comparing with the currently available Fermi/LAT GRB and blazar data shows that there is room for significant emissions originating in the first stars era.
