Reduction of pteridines
Creators: name: Matsuura, Sadao
Publisher: name: The Australian National University
Year: 1961
Subjects: Pteridines

description: Summary: Reduction: The fifteen possible hydroxy- and polyhydroxypteridines were reduced, chemically and catalytically. Potassium borohydride, sodium dithionite, and potassium (or sodium) amalgam were used as the chemical reducing agents. Hydrogenation over palladium, platinum, and Raney-nickel were used for catalytic reductions. Except 2,4,7-trihydroxypteridine all these were successfully reduced by at least one of the above methods. Hyuroxypteridines lacking a hydroxy group in the pyrazine ring gave tetrahydropteridines and, in some cases, a dihydro-compound as well. Thus 2-hydroxypteridine gave 5,6,7, 8-tetraliydro-2-hydroxypteridine and also 3,4-dihydro-2-hydroxypteridine. The latter is the first example of the reduction of a pteridine in the pyrimidine ring.On the other hand, hydroxypteridines having a hydroxy group in the pyrazine ring gave only dihydro-compounds on reduction. Thus 6-hydroxypteridines gave 7,8-dihydro-6- hydroxypteridines, and 7-hydroxypteridines gave their 5,6- dihydro-derivatives.

description: The Hesburgh Libraries at the University of Notre Dame has implemented a lightweight mentorship program that provides a structure for recently hired employees to learn about the organization, to provide advice that considers the institutional context, and to elucidate the roles and responsibilities of library faculty. In the fall of 2012, the Hesburgh Libraries hired a Metadata and Digital Collections Librarian and the Organizational Development Librarian paired him with a senior manager overseeing IT in the Libraries. This chapter endeavors to first ground the readers in the literature related to mentoring, wellbeing, and the intersection of the two concepts. For the remainder of the chapter, the authors will discuss how their work together has matured their perspectives, how their professional relationship has evolved over time and helped them both to practice new skills and learn new approaches together, how the meetings provide a safe space to talk through challenges openly, and offer some tips on how to start a mentoring relationship on one’s own in that context. The authors hope to offer a low threshold means to engage in effective mentoring.

description: Mandailing is in the south of what Dutch scholars call the Gayo-Alas-Batak law area of Indonesia. This law area was characterised by the presence of patriclans inhabiting their won territory, small self-governing communities - sometimes single villages, sometimes a group of villages - a dominant clan in the community which supplied the community head (radja), and immigrant clans with representatives on the village council. Among the Batak matrilateral cross cousin marriage was preferred, the clans being asymmetrically organised so that each clan was related to a wife-giving clan on the one hand and a wife-receiving clan on the other. There was a division of society into nobles (radjas), commoners and slaves. Warfare was endemic, but not very destructive of persons or property. Religion and magic were Hindu in origin, belief in the tondi (m) or soul being a prominent feature. The Batak were divided linguistically into Karo, Dairi, Timur, Toba and Angkola-Mandailing speakers. It is likely that the Mandailingers spread southward from Lake Toba. They met the northward moving Menangkabau at the southern border of Mandailing, and subsequently some 100,000 Mandailingers, in a total of about one million Bataks, were converted to Islam.

description: In the canonical formalism for the free electromagnetic field a solution to Maxwell's equations is customarily identified with its initial gauge potential (in Coulomb gauge) and initial electric field, which together determine a point in phase space. The solutions to Maxwell's equations, all of whose plane waves in their plane wave expansions have positive helicity, thereby determine a subspace of phase space. We will show that this subspace consists of initial gauge potentials which lie in the positive spectral subspace of the operator curl together with initial electric fields conjugate to such potentials. Similarly for negative helicity. Helicity is thereby characterized by the spectral subspaces of curl in configuration space. A gauge potential on three-space has a Poisson extension to a four dimensional Euclidean half space, defined as the solution to the Maxwell-Poisson equation whose initial data is the given gauge potential. We will show that the extension is anti-self dual if and only if the gauge potential lies in the positive spectral subspace of curl. Similarly for self dual extension and negative spectral subspace. Helicity is thereby characterized for a normalizable electromagnetic field by the canonical formalism and (anti-)self duality. For a non-abelian gauge field on Minkowski space a plane wave expansion is not gauge invariant. Nor is the notion of positive spectral subspace of curl. But if one replaces the Maxwell-Poisson equation by the Yang-Mills-Poisson equation then (anti-)self duality on the Euclidean side induces a decomposition of (now non-linear) configuration space similar to that in the electromagnetic case. The strong analogy suggests a gauge invariant definition of helicity for non-abelian gauge fields. We will provide further support for this view.

description: Background and purpose — Long-term fixation of cemented femoral stems relies on several factors including cement adhesion and fatigue. Hi-Fatigue is a newer third-generation bone cement with low-viscosity properties at room temperature, good mechanical strength, and stable bone–cement interface in a laboratory testing environment. Palacos bone cement has excellent 10-year survival and is considered gold standard. We compared stem subsidence after fixation with Hi-Fatigue and Palacos bone cements using radiostereometry. Patients and methods — In a patient-blinded randomized controlled trial, 52 patients (30 women) at mean age 76 years (71–87) with osteoarthrosis and no osteoporosis received Hi-Fatigue G or Palacos R + G cement fixation of collarless, polished, double-tapered stems (CPT). Tantalum beads were inserted in the periprosthetic bone. Supine stereoradiographs were obtained postoperatively, 3 months, 6 months, 1 year, and 2 years after surgery. Oxford Hip Score (OHS) and VAS pain were recorded preoperatively and 1 and 2 years after surgery. Cement working times and properties were registered. Results — At 2 years, mean stem subsidence of 1.12 mm (95% CI 0.96–1.29) for Hi-Fatigue and 1.19 mm (CI 1.03–1.34) for Palacos was similar. Likewise, stem version was comparable between cement groups. Mean OHS and VAS pain were similar between cement groups. Cement working times were similar between cement groups, but the mean curing time was longer for Hi-Fatigue (13.7 min) than for Palacos (11.6 min). Interpretation — We found similar and generally low migration of CPT femoral stems inserted with Hi-Fatigue and Palacos bone cement until 2 years’ follow-up, which indicates a good long-term survival of polished taper femoral stems inserted with both cement types.

description: We report the fabrication of nickel nanowires with parallel growth-twin structures (‘twin lamella’ along the wire axis) by electrochemical deposition, and demonstrate an interesting twin ‘unzipping’ phenomenon in such nanotwinned nanowires under bending. Through in situ TEM, we found that ‘unzipping’ of twin lamella was achieved by gradually increasing twin spacing along the wire axis via a layer-by-layer twin boundary migration process. Molecular dynamics simulations suggest that partial dislocation slip is responsible for activating the ‘unzipping’, with a multi-step-process involving dislocation loop initiation, expansion and partially annihilation. Our work could provide new insights into the deformation mechanisms of nanotwinned 1-D metallic nanostructures. IMPACT STATEMENT Nickel nanowires with parallel-twin structures were fabricated and demonstrated an interesting twin lamella ‘unzipping’ behavior upon flexural bending, which provides new insights into the deformation mechanisms of nanotwinned metallic materials.

description: Improvements in computational speed lead to better resolutions in Earth System Models (ESM) allowing them to resolve scales of a few kilometers. The volume of the resulting data greatly increases with the improvements in resolution and introduces a challenge to processing and storing these results.While modern HPC systems provide petabyte-scale capacity for file storage, analyzing such data on local user systems can become a prohibitive bottleneck. Beyond the sheer demands on processing high-volume ESM data, there is also increasing demand to make them FAIR and in particular findable.The goal of the “Easier” module of the Warmworld project aims to simplify the access to ESM data from different HPC centers, in particular the German Climate Computing Center (DKRZ) and the Jülich Supercomputing Centre (JSC). One aspect is the creation of a joined catalog following the SpatioTemporal Asset Catalogs (STAC) specification. This allows browsing data available at both centers. Details on the STAC implementation will be presented by Kameswar Rao Modali et al. at this General Assembly (EGU25-10288).The catalog also contains links to access the data, either as a download or later as zarr-stream. The explicit implementation of the required REST-APIs depends on the infrastructure, hardware and software, of the data centers as well as the organization of the stored data.As the first data backend at JSC, we set up a Fields DataBase (FDB), developed by ECMWF, to store the ESM results as multi-dimensional data cubes. For data retrieval, we provide a download service based on the MARS language for identifying data within the FDB and the UNiform Interface to COmputing REsources (UNICORE) for an automated access to our HPC system. The download service integrates the Helmholtz authentication and authorization infrastructure. This will allow a large number of institutions to access these services with the possibility to control access and resource use.Our poster will provide details on the ongoing implementation and combination of the various tools and services used at JSC as well as further details on the implementation on our HPC systems. In addition, we will provide first information about the planned authorization for different data accesses and also show the performance of different components with a set of benchmarks.

description: We calculate the linear magneto-optical Kerr rotation for CeSb in the near-infrared spectral range. Using an exact formula for large Kerr rotation angles and a simplified electronic structure of CeSb we find at \hbar ω= 0.46 eV a Kerr rotation of 90 degree which then for decreasing ωjumps to -90 degree as recently observed. We identify the general origin of possible 180 degree polarization rotations as resulting from mainly nonmagnetic optical properties, in particular from the ratio of the dominant interband resonance frequency to the plasma frequency. The dependence of the Kerr rotation on moments and magnetization is discussed.

description: We analyze the quantum mechanics of the friction experienced by a small system as it moves non-destructively with velocity $v$ over a surface. Specifically, we model the interactions between the system and the surface with a \textit{collision model}. We show that, under weak assumptions, the magnitude of the friction induced by this interaction decreases as $1/v$ for large velocities. Specifically, we predict that this phenomenon occurs in the Zeno regime, where each of the system's successive couplings to subsystems of the surface is very brief. In order to investigate the friction at low velocities and with velocity-dependent coupling strengths, we motivate and develop \textit{one-dimensional convex collision models}. Within these models, we obtain an analytic expression for the general friction-velocity dependence. We are thus able to determine exactly the conditions under which the usual friction-velocity dependency arises. Finally, we give examples that demonstrate the possibility, in principle, of anti-friction, in which case the system is accelerated by its interaction with the surface, a phenomenon associated with active materials and inverted level populations.

description: Background and purpose — The prevalence of obesity is on the rise, becoming a worldwide epidemic. The main purpose of this register-based observational study was to investigate whether different BMI classes are associated with increased risk of reoperation within 2 years, risk of revision within 5 years, and the risk of dying within 90 days after primary total hip arthroplasty (THA). We hypothesized that increasing BMI would increase these risks. Patients and methods — We analyzed a cohort of 83,146 patients who had undergone an elective THA for primary osteoarthritis between 2008 and 2015 from the Swedish Hip Arthroplasty Register (SHAR). BMI was classified according to the World Health Organization (WHO) into 6 classes: < 18.5 as underweight, 18.5–24.9 as normal weight, 25–29.9 as overweight, 30–34.9 as class I obesity, 35–39.9 as class II obesity, and ≥ 40 as class III obesity. Results — Both unadjusted and adjusted parameter estimates showed increasing risk of reoperation at 2 years and revision at 5 years with each overweight and obesity class, mainly due to increased risk of infection. Uncemented and reversed hybrid fixations and surgical approaches other than the posterior were all associated with increased risk. Obesity class III (≥ 40), male sex, and increasing ASA class were associated with increased 90-day mortality. Interpretation — Increasing BMI was associated with 2-year reoperation and 5-year revision risks after primary THA where obese patients have a higher risk than overweight or normal weight patients. As infection seems to be the main cause, customizing preoperative optimization and prophylactic measures for obese patients may help reduce risk.

description: We have derived the general solution of a wave equation describing the dynamics of two-layere viscoelastic polymer materials of arbitrary thickness deposited on solid (quartz) surfaces in a fluid environment. Within the Voight model of viscoelastic element, we calculate the acoustic response of the system to an applied shear stress, i.e. we find the shift of the quartz generator resonance frequency and of the dissipation factor, and show that it strongly depends on the viscous loading of the adsorbed layers and on the shear storage and loss moduli of the overlayers. These results can readily be applied to quartz crystal acoustical measurements of the viscoelasticity of polymers, which conserve their shape under the shear deformations and do not flow, and layered structures such as protein films adsorbed from solution onto the surface of self-assembled monolayres.

description: Using the density matrix renormalization group (DMRG) technique, we carry out a large scale numerical calculation for the S=2 antiferromagnetic Heisenberg chain. Performing systematic scaling analysis for both the chain length $L$ and the number of optimal states kept in the iterations $m$, the Haldane gap $Δ(2)$ is estimated accurately as $(0.0876\pm0.0013)J$. Our systematic analysis for the S=2 chains not only ends the controversies arising from various DMRG calculations and Monte Carlo simulations, but also sheds light on how to obtain reliable results from the DMRG calculations for other complicated systems.

description: Background and purpose — Gait analysis performed under increased physical demand may detect differences in gait between total (THA) versus resurfacing hip arthroplasty (RHA), which are not measured at normal walking speed. We hypothesized that patients after RHA would reach higher walking speeds and inclines compared with THA. Additionally, an RHA would enable a more natural gait when comparing the operated with the healthy contralateral hip. Patients and methods — From a randomized controlled trial comparing THA with RHA with at least 5 years’ follow-up patients with a UCLA score of more than 3 points (n = 34) were included for an instrumented treadmill gait analysis. 25 patients with a unilateral implant (primary analysis—16 THA versus 9 RHA) and 9 patients with a bilateral implant (sub-analysis—n = 5 RHA + THA; n = 4 THA + THA). Spatiotemporal parameters, ground reaction forces, and range of motion were recorded at increasing walking speeds and inclines. Functional outcome scores were obtained. Results — At a normal walking speed of 1.1 m/s and at increasing inclines no differences were recorded in gait between the 2 groups with a unilateral hip implant. With increasing walking speed the RHA group reached a higher top walking speed (TWS) (adjusted difference 0.07 m/s, 95% CI –0.11 to 0.25) compared with THA. Additionally, RHA patients tolerated more weight on the operated side at TWS (155 N, CI 49–261) and as such weight-bearing approached the unaffected contralateral side. For the RHA group a “between leg difference” of 8 N (CI 3–245) was measured versus –129 N (CI –138 to –29) for THA (adjusted difference 144 N, CI 20–261). Hip flexion of the operated side at TWS was higher after RHA compared with THA (adjusted difference 8°, CI 1.7–14). Interpretation — In this study RHA patients reached a higher walking speed, and preserved a more normal weight acceptance and a greater range of hip flexion against their contralateral healthy leg as compared with patients with a THA.

description: We present computed spectra, as seen by a distant observer, from the accretion disc around a rapidly rotating neutron star. Our calculations are carried out in a fully general relativistic framework, with exact treatment of rotation. We take into account the Doppler shift, gravitational redshift and light bending effects in order to compute the observed spectrum. We find that light bending significantly modifies the high-energy part of the spectrum. Computed spectra for slowly rotating neutron stars are also presented. These results would be important for modelling the observed X-ray spectra of Low Mass X-ray Binaries containing fast spinning neutron stars.

The sensor is based on a ground-facing camera and a single-board Linux-based embedded computer with a multimedia System on a Chip (SoC). The SoC features a hardware video encoder which is used to estimate the optical flow online. The optical flow is then used in combination with a distance sensor to estimate the vehicle's velocity. The proposed sensor is compared to a similar existing solution and evaluated in both indoor and outdoor environments.

(Figs 107–122)
 Diagnosis. Opsiphanes badius stat. rest. differs from Opsiphanes quirinus stat. rest. and Opsiphanes quiteria, the closest related species, in having the DFW with a narrower and uneven oblique band, visibly interrupted on CuA 2 - 2A, a character evident in males. No significant differences were found between females of Opsiphanes badius stat. rest. and Opsiphanes quirinus stat. rest., except in genetic distance and geographic distribution. The female of Opsiphanes badius stat. rest. is also similar to the female of Opsiphanes quiteria quirinalis in the DFW whitish oblique band, but differs from Opsiphanes quiteria quirinalis in the DHW rusty red color in the postdiscal region, between M 2 and CuA 2 (Figs 107a, 108a). Molecular analyses recovered Opsiphanes badius stat. rest. as closely related to Opsiphanes quirinus stat. rest. and Opsiphanes quiteria (Fig. 2) (genetic distance 1.6–2.4% and 1.9–2.5%, respectively).

 Diagnosis. Opsiphanes sallei differs from Opsiphanes farrago stat. nov. in having the DFW with a strongly angled oblique band on M 3 -CuA 1 (Fig. 95a). Molecular analyses recovered Opsiphanes sallei as closely related to Opsiphanes farrago stat. nov. (Fig. 2) (genetic distance 2.9-3.1%).
 Male genitalia. Tegumen in dorsal view with anterior margin with concavity in the median region and almost the same width as the posterior margin; anterior projection of saccus in lateral view twice as long as dorsal arms of saccus, in ventral view with a dilated anterior region (Fig. 100).
 Female genitalia. Lamella antevaginalis membranous medially and sclerotized laterally; lamella postvaginalis as a triangular plate that tapers gradually in the distal portion, rounded medially, nearly the same size as the ostium; ostium with weaker sclerotization than lamella ante and postvaginalis (Fig. 101).
 Variation. Opsiphanes sallei colombiana and Opsiphanes sallei nicandrus vary in the following characters: DFW, size of the patches that form the oblique band; when small, these patches form a discontinuous band. DHW, the width of submarginal band. VHW, the size of the eyespot between Sc+R 1 and M 1, and the width of its darkbrown ring; and the size and shape of the eyespot between M 3 and CuA 2 (Figs 96–99).

description: We study theoretically the phase diagram of perovskite manganites taking into account the double degeneracy of the $e_g$ orbitals in a $Mn^{3+}$ ion. A rich phase diagram is obtained in the mean field theory at zero temperature as functions of $x$ (hole concentration) and $J_S$ (antiferromagnetic interaction between $t_{2g}$ spins). The global features of the phase diagram is understood in terms of the superexchange and double exchange interactions, which are strongly depends on types of the occupied $e_g$ orbitals. The strong electron correlation induces the orbital polarization, which controls the dimension of the conduction band. A sequential change of the spin and orbital structures with doping holes is consistent with the recent experiments. In particular, metallic A-type (layered) antiferromagnetic state is found for $x\sim0.5$ with the uniform $d_{x^2-y^2}$ orbital ordering. Effects of the Jahn-Teller distortion are also studied. A short version of this paper has been already published (to appear in PRB-rapid June), but this paper contains additional and more detailed results.

description: The initial aim of this thesis is to provide a factual account of the development of the various branches of education in New South Wales from the collapse of the Anglican monopoly about the time of Governor Bourke's arrival until the Public Instruction Act of 1880, which established a structure which has endured almost to our own day. Of equal importance with this aim has been an attempt to identify the persistent, broad features of N.S.W. education which, taken as a whole, went to make up a distinctive educational tradition.

description: When an optical beam propagates through dielectric blocks, its optical phase is responsible for the path of the beam. In particular, the first order Taylor expansion of the geometrical part reproduces the path predicted by the Snell and reflection laws whereas the first order expansion of the Fresnel phase leads to the Goos-Haenchen shift. In this paper, we analyze the effects of the second order Taylor expansion of the geometrical phase on the shape of the optical beam and show how it affects the transversal symmetry of Hermite-Gaussian beams. From the analytical expression of the transmitted beam, it is possible to determine in which transversal and parallel dielectric blocks configuration the transversal symmetry breaking is maximized or when the symmetry is recovered. We also discuss the axial spreading delay.

description: We study the phase diagram of the continuum traffic flow model of a highway with an on-ramp. Using an open boundary condition, traffic states and metastabilities are investigated numerically for several representative values of the upstream boundary flux $f_{up}$ and for the whole range of the on-ramp flux $f_{rmp}$. An inhomogeneous but time-independent traffic state (standing localized cluster state) is found and related to a recently measured traffic state. Due to the density gradient near the on-ramp, a novel traffic jam can occur even when the downstream density is below the critical density of the usual traffic jam formation in homogeneous highways, and its structure varies qualitatively with $f_{rmp}$. The free flow, the recurring hump (RH) state, and the traffic jam can all coexist in a certain metastable region where the free flow can undergo phase transitions either to the RH state or to the traffic jam state. We also find two nontrivial analytic solutions. These solutions correspond to the standing localized cluster state and the homogeneous congested traffic state (one form of the novel traffic jam),which are observed in numerical simulations.

description: Background and purpose — The multidisciplinary Clinical Practice Guideline for diagnosis and treatment of subacromial pain syndrome (SAPS) was created in 2012 by the Dutch Orthopedic Association. In brief, it stated that SAPS should preferably be treated nonoperatively. We evaluated the effect of the implementation of the guideline on the number of shoulder surgeries for SAPS in the Netherlands (17 million inhabitants). Patients and methods — An observational study was conducted with the use of aggregated data from the national database of the Dutch Health Authority from 2012 to 2016. Information was collected on patients referred to and seen at orthopedic departments. Data from the following Diagnoses Related Groupings were analyzed: 1450 (tendinitis supraspinatus) and 1460 (rotator cuff tear). Results — In 2016 fewer patients were diagnosed with tendinitis supraspinatus than in 2012—a decrease from 49,491 to 44,662 (10%). Of the patients diagnosed with tendinitis, 14% were treated surgically in 2012; this number dropped to 9% by 2016. More patients with a rotator cuff tear were diagnosed in 2016 than in 2012, an increase from 17,793 to 23,389 (32%), fewer were treated surgically: 30% in 2012, compared with 25% in 2016. Interpretation — After introducing the multidisciplinary Clinical Practice Guideline “Diagnosis and treatment of subacromial pain syndrome,” a decrease in shoulder surgeries for related diagnoses was observed in the Netherlands. The introduction and dissemination of this guideline seems to have contributed to the implementation of more appropriate health care and prevention of unnecessary surgeries.
Primordial Feature at the Scale of Superclusters of Galaxies

description: We investigate a spatially-flat cold dark matter model (with the matter density parameter $Ω_m=0.3$) with a primordial feature in the initial power spectrum. We assume that there is a bump in the power spectrum of density fluctuations at wavelengths $λ\sim 30-60h^{-1}$Mpc, which correspond to the scale of superclusters of galaxies. There are indications for such a feature in the power spectra derived from redshift surveys and also in the power spectra derived from peculiar velocities of galaxies. We study the mass function of clusters of galaxies, the power spectrum of the CMB temperature fluctuations, the rms bulk velocity and the rms peculiar velocity of clusters of galaxies. The baryon density is assumed to be consistent with the BBN value. We show that with an appropriately chosen feature in the power spectrum of density fluctuations at the scale of superclusters, the mass function of clusters, the CMB power spectrum and peculiar velocities are in good agreement with the observed data.

description: We discuss some aspects of a new noncombinatorial fermionic approach to the two-dimensional dimer problem in statistical mechanics based on the integration over anticommuting Grassmann variables and factorization ideas for dimer density matrix. The dimer partition function can be expressed as a Gaussian fermionic integral. For regular lattices, the analytic solution then follows by passing to the momentum space for fermions.

The residential system in the protected Malay States, 1874-1895

description: This study deals with the establishment of British rule - the 'Residential system' as it was known to contemporaries - in the Malay Peninsula. It was introduced between 1874 and 1895 into the three west coast states, Perak, Selangor and Negri Sembilan, and the east coast state of Pahang. The study focuses on Perak and Selangor, where British rule was first introduced, the problems of government first in countered, and policies evolved to deal with them as they arose. The term 'British rule', used of the form of administration in the Malay states during the period, is itself a challenge to conventional interpretations, which represent the British officers as advisers to the Malay rulers, through whom the government of the country was carried on. The interpretation breaks down on investigation, but the theory of government, the way in which it developed and there alities which it covered remain to be discussed. The thesis describes the accommodation reached between fact and fiction, and the manner in which it was established, the way in which the Secretary of State for the Colonies, the Governor of the Straits Settlements and the Residents exercised authority in the states nominally under 'advice', and finally the part played by Malay rulers and chiefs and Malay local authorities in the government of the states. The subject of this thesis was originally conceived as a study both of the formation of British policy and its execution through the structure of government in Malaya. It was intended to consider how far uniformity in government had been achieved before 1895, when the state administrations were placed under the control of a Federal chief executive, their civil services amalgamated and many of their departments placed under Federal heads. The whole subject is a large one, and has not been covered in the manner originally in tended. The formation of policy is discussed at length, but the structure of government has been treated selectively. The relations between the Colonial Office and the states are dealt with, and the relations between the Governor, the Resident, the Sultan and the Chinese headmen as reflected in the workings of the State Council, are dealt with in a paper on the State Councils submitted as Appendix III. The policies of the state governments and the implications of Federation have been omitted. A monograph published by the writer in 1954, and bearing on the development of the residential system in Perak is here with submitted in amplification of some of the points made in the study.

description: We present a method for calibrating the flux density scale for images generated by the Amsterdam ASTRON Radio Transient Facility And Analysis Centre (AARTFAAC). AARTFAAC produces a stream of all-sky images at a rate of one second in order to survey the Northern Hemisphere for short duration, low frequency transients, such as the prompt EM counterpart to gravitational wave events, magnetar flares, blazars, and other as of yet unobserved phenomena. Therefore, an independent flux density scaling solution per image is calculated via bootstrapping, comparing the measured apparent brightness of sources in the field to a reference catalogue. However, the lack of accurate flux density measurements of bright sources below 74 MHz necessitated the creation of the AARTFAAC source catalogue, at 60 MHz, which contains 167 sources across the Northern Hemisphere. Using this as a reference results in a sufficiently high number of detected sources in each image to calculate a stable and accurate flux scale per one second snapshot, in real-time.

description: The Landauer approach to transport in mesoscopic conductors has been generalized to allow for strong electronic correlations in a single-channel quantum wire. We describe in detail how to account for external voltage sources in adiabatic contact with a quantum wire containing a backscatterer of arbitrary strength. Assuming that the quantum wire is in the Luttinger liquid state, voltage sources lead to radiative boundary conditions applied to the displacement field employed in the bosonization scheme. We present the exact solution of the transport problem for arbitrary backscattering strength at the special Coulomb interaction parameter g=1/2.
