description: Between 2013 and 2018 a stratigraphic sondage was conducted in Yeha under the umbrella of the Ethiopian-German project. Aim of the excavation was to get a chronological sequence of the settlement. The lowest stratum of the trench, situated directly above the natural rock, revealed a settlement predecessor of the late 2nd millennium BC followed by Ethio-Sabaean occupation layers from the first half of the 1st millennium BC. After a gap in the second half of the 1st millennium BC settlement started again in the early Aksumite period. From the late Aksumite period onwards a continuous usage of the site can be assumed until modern times.

description: We report on the analysis of XMM-Newton observations of RX J1347.5-1145 (z=0.451), the most X-ray-luminous galaxy cluster. We present a detailed total and gas mass determination up to large distances (~1.7 Mpc), study the scaling properties of the cluster, and explore the role of AGN heating in the cluster cool core. By means of spatially resolved spectroscopy we derive density, temperature, entropy, and cooling time profiles of the intra-cluster medium. We compute the total mass profile of the cluster in the assumption of hydrostatic equilibrium. If the disturbed south-east region of the cluster is excluded from the analysis, our results on shape, normalization, scaling properties of density, temperature, entropy, and cooling time profiles are fully consistent with those of relaxed, cool core clusters. We compare our total and gas mass estimates with previous X-ray, lensing, dynamical, and SZ studies. We find good agreement with other X-ray results, dynamical mass measurements, weak lensing masses and SZ results. We confirm a discrepancy of a factor ~2 between strong lensing and X-ray mass determinations and find a gross mismatch between our total mass estimate and the mass reconstructed through the combination of both strong and weak lensing. We explore the effervescent heating scenario in the core of RX J1347.5-1145 and find support to the picture that AGN outflows and heat conduction are able to quenching radiative cooling.

description: The X-ray spectra of Low Mass X-ray Binaries (LMXB) can change on short time-scales, making it difficult to follow their spectral characteristics in detail through model fitting. Colour-colour (C-C) diagrams are therefore often used as alternative, model independent, tools to study the spectral variability of these sources. The INTEGRAL mission, with its high sensitivity, large field of view and good angular resolution, is well suited to study the hard X-ray properties of LMXBs. In particular the ISGRI imager on board of INTEGRAL allows the regular monitoring of the sources in the less frequently studied domain above 20 keV. In this proceeding, C-C diagrams have been made with data from the INTEGRAL public archive; a search is made for systematic differences in the C-C diagrams between black hole candidates (BH) and neutron stars (NS) in LMXBs using a moments analysis method.

Anomalous Josephson Hall effect charge and transverse spin currents in superconductor/ferromagnetic insulator/superconductor junctions

Publisher: name: Universität Regensburg
Year: 2020
Subjects: subject: 530 Physik

description: Interfacial spin-orbit coupling in Josephson junctions offers an intriguing way to combine anomalous Hall and Josephson physics in a single device. We study theoretically how the superposition of both effects impacts superconductor/ferromagnetic insulator/superconductor junctions' transport properties. Transverse momentum-dependent skew tunneling of Cooper pairs through the spin-active ferromagnetic insulator interface creates sizable transverse Hall supercurrents, to which we refer as anomalous Josephson Hall effect currents. We generalize the Furusaki-Tsukada formula, which got initially established to quantify usual (tunneling) Josephson current flows, to evaluate the transverse current components and demonstrate that their amplitudes are widely adjustable by means of the spin-orbit coupling strengths or the superconducting phase difference across the junction. As a clear spectroscopic fingerprint of Josephson junctions, well-localized subgap bound states form around the interface. By analyzing the spectral properties of these states, we unravel an unambiguous correlation between spin-orbit coupling-induced asymmetries in their energies and the transverse current response, founding the currents' microscopic origin. Moreover, skew tunneling simultaneously acts like a transverse spin filter for spin-triplet Cooper pairs and complements the discussed charge current phenomena by their spin current counterparts. The junctions' universal spin-charge current cross ratios provide valuable possibilities to experimentally detect and characterize interfacial spin-orbit coupling.

description: Archaeological work at Dahshur concentrated on excavating several structures linked to the Bent Pyramid of Snofru. A new excavation project was initiated in an area north of the valley temple of this pyramid, where settlement structures had been revealed through a geomagnetic survey. Here, the remains of a house, made of mud- and sandbricks and covering an area of about 35 × 30 m, came to light. All pottery fragments date to the early 4th dynasty, possibly linking the house to the process of pyramid building. Excavations were continued in three areas already under study in the past: the harbour and the lower causeway, as well as a transportation ramp made of limestone blocks originally deriving from the valley temple of the Bent Pyramid.
Connection between zero-energy Yu-Shiba-Rusinov states and 0−π transitions in magnetic Josephson junctions

description: We study theoretically the bound state spectrum and 0−π transitions in ballistic quasi-one-dimensional superconductor/ferromagnetic insulator/superconductor Josephson junctions. In addition to the Andreev bound states, stemming from the phase coherence, the magnetic barrier gives rise to qualitatively different Yu-Shiba-Rusinov (YSR) bound states with genuine spectral features and spin characteristics. We show that zero-energy YSR states are much more robust against the presence of scalar tunneling than their Andreev counterparts and also fingerprint a quantum phase transition from the junctions' 0 into the π phase, connected to a measurable reversal of the Josephson current; this evidence persists also in the presence of Rashba spin-orbit coupling.

description: Effect handlers have been gathering momentum as a mechanism for modular programming with user-defined effects. Effect handlers allow for non-local control flow mechanisms such as generators, async/await, lightweight threads and coroutines to be composably expressed. We present a design and evaluate a full-fledged efficient implementation of effect handlers for OCaml, an industrial-strength multi-paradigm programming language. Our implementation strives to maintain the backwards compatibility and performance profile of existing OCaml code. Retrofitting effect handlers onto OCaml is challenging since OCaml does not currently have any non-local control flow mechanisms other than exceptions. Our implementation of effect handlers for OCaml: (i) imposes a mean 1% overhead on a comprehensive macro benchmark suite that does not use effect handlers; (ii) remains compatible with program analysis tools that inspect the stack; and (iii) is efficient for new code that makes use of effect handlers.

description: The Balloon-borne Large Aperture Submillimeter Telescope (BLAST) is a sub-orbital experiment designed to study the process of star formation in local galaxies (including the Milky Way) and in galaxies at cosmological distances. Using a 2-m Cassegrain telescope, BLAST images the sky onto a focal plane, which consists of 270 bolometric detectors split between three arrays, observing simultaneously in 30% wide bands, centered at 250, 350, and 500 microns. The diffraction-limited optical system provides a resolution of 30" at 250 microns. The pointing system enables raster-like scans with a positional accuracy of ~30", reconstructed to better than 5" rms in post-flight analysis. BLAST had two successful flights, from the Arctic in 2005, and from Antarctica in 2006, which provided the first high-resolution and large-area (~0.8-200 deg^2) submillimeter surveys at these wavelengths. As a pathfinder for the SPIRE instrument on Herschel, BLAST shares with the ESA satellite similar focal plane technology and scientific motivation. A third flight in 2009 will see the instrument modified to be polarization-sensitive (BLAST-Pol). With its unprecedented mapping speed and resolution, BLAST-Pol will provide insights into Galactic star-forming nurseries, and give the necessary link between the larger, coarse resolution surveys and the narrow, resolved observations of star-forming structures from space and ground based instruments being commissioned in the next 5 years.

Acceptability of alternative classroom treatment strategies and factors affecting teacher’s ratings
Creators: name: McKee, William Treen
Publisher: name: University of British Columbia
Year: 2010

description: A screening sample of 107 elementary school teachers completed a 16-item multiple-choice measure of knowledge of behavioral principles. Two subject groups, each consisting of 32 regular classroom teachers, were randomly selected for high and low knowledge groups based on scores on the knowledge measure. High and low knowledge group teachers were given random assignment to one of two clinical case descriptions. Both descriptions were of a 9-year old boy who is presented as being very aggressive, and who does not follow adult instructions. The two cases differed only in the type of background attributed to each. One is described as coming to the regular classroom as a result of 'mainstreaming', having been previously in a special class setting. The other case description makes no reference to mainstreaming or to previous placement. Teachers in all conditions evaluated the acceptability of four alternative classroom treatment strategies for children: Medication, Time Out from Reinforcement, Reinforcement of Incompatible Behavior, and Positive Practice. Teachers in the high and low knowledge groups read the assigned case description, and then rated the acceptability of the treatments in a 4 x 4 replicated Latin-square design using treatment acceptability measures developed by Kazdin (1980a). Following treatment ratings, subjects completed a questionnaire which, in part, asked subjects to rank order the described treatments on the basis of likelihood of each being used by the subject doing the rating. High knowledge group teachers rated treatments as more acceptable than did low knowledge group teachers on the primary dependent measure. Treatments were readily differentiated in terms of acceptability. Reinforcement was rated more acceptable than Time Out and Positive Practice, which did not differ from each other in terms of acceptability. Medication was rated lower in acceptability than the other treatments. Treatment acceptability ratings were not different for the two case descriptions. The results of the ranking of treatments on the Case and Treatment Questionnaire generally followed those of the rating procedure. The results of the analyses indicate that teachers do differentiate treatments in terms of acceptability using both the rating and ranking procedures. It is also apparent that the high knowledge group teachers tend to rate alternative classroom treatments as more acceptable than do the low knowledge group teachers. These findings are discussed, and implications for education and for future research are presented.

description: We calculate the Chern classes and Chern numbers for the natural almost Hermitian structures of the partial flag manifolds F_n=SU(n+2)/S(U(n)\times U(1)\times U(1)). For all n>1 there are two invariant complex algebraic structures, which arise from the projectivizations of the holomorphic tangent and cotangent bundles of complex projective spaces. The projectivization of the cotangent bundle is the twistor space of a Grassmannian considered as a quaternionic Kähler manifold. There is also an invariant nearly Kähler structure, because F_n is a 3-symmetric space. We explain the relations between the different structures and their Chern classes, and we prove that F_n is not geometrically formal.

Incidence of the host galaxy on the measured optical linear polarization of blazars

description: We study the incidence of the underlying host galaxy light on the measured optical linear polarization of blazars. Our methodology consists of the implementation of simulated observations obtained under different atmospheric conditions, which are characterised by the Gaussian $σ$ of the seeing function. The simulated host plus active nucleus systems span broad ranges in luminosity, structural properties, redshift, and polarization; this allows us to test the response of the results against each of these parameters. Our simulations show that, as expected, the measured polarization is always lower than the intrinsic value, due to the contamination by non-polarized star light from the host. This effect is more significant when the host is brighter than the active nucleus, and/or a large photometric aperture is used. On the other hand, if seeing changes along the observing time under certain particular conditions, spurious microvariability could be obtained, especially when using a small photometric aperture. We thus give some recommendations in order to minimise both unwanted effects, as well as basic guidelines to estimate a lower limit of the true (nuclear) polarization. As an example, we apply the results of our simulations to real polarimetric observations, with high temporal resolution, of the blazar PKS 0521-365.

description: In this study, a novel type of Fourier transform radio spectrometer (termed as all-digital radio spectrometer; ADRS) has been developed in which all functionalities comprising a radio spectrometer including a sampler and Fourier computing unit were implemented as a soft-core on a field-programmable gate array (FPGA). A delay-line-based ramp-compare analog-to-digital converter (ADC), one of completely digital ADC, was used, and two primary elements of the ADC, an analog-to-time converter (ATC) and a time-to-digital converter (TDC), were implemented on the FPGA. The sampling rate of the ADRS $f$ and the quantization bit rate $n$ are limited by the relation, $τ= \frac{1}{2^{n}f}$, where $τ$ is the latency of the delay element of the delay-line. Given that the typical latency of the delay element implemented on FPGAs is $\sim10$ ps, adoption of a low quantization bit rate, which satisfies the requirements for radio astronomy, facilitates the realization of a high sampling rate up to $\sim$100 GSa/s. In addition, as the proposed \ADRS does not require a discrete ADC and can be implemented on mass-produced evaluation boards, its fabrication cost is much lower than that of conventional spectrometers. The ADRS prototype was fabricated with values of $f$ = 600 MSa/s and $n$ = 6.6 using a PYNQ-Z1 evaluation board, with a $τ$ of 16.7 ps. The performance of the prototype, including its linearity and stability, was measured, and a test observation was conducted using the Osaka Prefecture University 1.85-m mm-submm telescope; this confirmed the potential application of the prototype in authentic radio observations. With 10 times better cost performance ($\sim$800 USD GHz$^{-1}$) than conventional radio spectrometers, the prototype facilitates cost-effective coverage of intermediate frequency (IF) bandwidths of $\sim100$ GHz in modern receiver systems.

description: Motivated by recent progress in calculating field theory amplitudes, we study applications of the basic ideas in these developments to the calculation of amplitudes in string theory. We consider in particular both non-Abelian and Abelian open superstring disk amplitudes in a flat space background, focusing mainly on the four-dimensional case. The basic field theory ideas under consideration split into three separate categories. In the first, we argue that the calculation of alpha'-corrections to MHV open string disk amplitudes reduces to the determination of certain classes of polynomials. This line of reasoning is then used to determine the alpha'^3-correction to the MHV amplitude for all multiplicities. A second line of attack concerns the existence of an analog of CSW rules derived from the Abelian Dirac-Born-Infeld action in four dimensions. We show explicitly that the CSW-like perturbation series of this action is surprisingly trivial: only helicity conserving amplitudes are non-zero. Last but not least, we initiate the study of BCFW on-shell recursion relations in string theory. These should appear very naturally as the UV properties of the string theory are excellent. We show that all open four-point string amplitudes in a flat background at the disk level obey BCFW recursion relations. Based on the naturalness of the proof and some explicit results for the five-point gluon amplitude, it is expected that this pattern persists for all higher point amplitudes and for the closed string.

Among the key results is a generating function in closed form leading to short and transparent derivations of recursion relations and an addition theorem. The complementary polynomials satisfy a hypergeometric-type differential equation themselves, have a three-term recursion among others and obey Rodrigues formulas. Applications to the classical polynomials are given.

description: The pairing of fermions is at the heart of superconductivity and superfluidity. The recent experimental realization of strongly interacting atomic Fermi gases has opened a new, controllable way to study novel forms of pairing and superfluidity. A major controversial issue has been the stability of superfluidity against an imbalance between the two spin components when the fermions interact resonantly. Here we present the phase diagram of a spin-polarized Fermi gas of $^6$Li atoms at unitarity, mapping out the superfluid phase versus temperature and density imbalance. Using tomographic techniques, we reveal spatial discontinuities in the spin polarization, the signature of a first-order superfluid-to-normal phase transition, which disappears at a tricritical point where the nature of the phase transition changes from first-order to second-order. At zero temperature, there is a quantum phase transition from a fully-paired superfluid to a partially-polarized normal gas. These observations and the implementation of an in situ ideal gas thermometer provide quantitative tests of theoretical calculations on the stability of resonant superfluidity.

description: We study the luminosity function of long gamma-ray bursts (LGRBs) using the peak flux obtained from three LGRB samples with known redshifts: (a) a sample of 251 LGRBs from the \textit{Swift/BAT} satellite/instrument; (b) a sample of 37 LGRBs from the \textit{Fermi/GBM} telescope; (c) a sample of 152 GRBs from the \textit{Konus-Wind} instrument. For the \textit{Swift/BAT} and \textit{Fermi/GBM} samples, we use data available on the Swift Burst Analyser websites (\url{http://www.swift.ac.uk/burst_analyser}; \citep{Evans:2010}) and (\url{http://swift.gsfc.nasa.gov/archive/grb/table/}) and on the Fermi website (\url{https://heasarc.gsfc.nasa.gov/}\url{W3Browse /fermi /fermigbrst.html}; \citep{{Gruber_2014}, {von_Kienlin_2014}, {Bhat_2016}}) to calculate the luminosity at the peak of the flux by using a cut-off power-law spectrum (CPL). For the \textit{Konus-Wind} sample, we use the Yonetoku correlation relationship \citep{Yonetoku:2010} to determine the isotropic luminosity from the energy at the peak of the flux measured in the source frame \citep{Minaev:2019}. With these three samples (totalling 439 GRBs), we use the Monte Carlo method to synthesize 10,000 "artificial" GRBs similar to each real GRB by considering that each physical quantity observed obeys a normal distribution, where the tabulated value and uncertainty represent the mean and the $3σ$ error. The results obtained for the luminosity function from our data samples are consistent with those published in previous works.

Emerging complexity in a simple model of the mechanical behaviour of rocks

description: We propose a mechanical model for the behaviour of rocks based on progressive damage at the elementary scale and elastic interaction. It allows us to simulate several experimental observations: mechanical behaviour ranging from brittle to ductile, fractal structure of the damage, powerlaw distribution of the damage avalanches. These macroscopic properties are not incorporated at the elementary scale, but are the results of the interaction between elements. This emerging complexity permits us to consider the strain rock process as a complex system characterized by non-linear dynamics.

description: In this article, we investigate the formation and disruption of a coronal sigmoid from the active region (AR) NOAA 11909 on 07 December 2013, by analyzing multi-wavelength and multi-instrument observations. Our analysis suggests that the formation of `transient' sigmoid initiated $\approx$1 hour before its eruption through a coupling between two twisted coronal loop systems. A comparison between coronal and photospheric images suggests that the coronal sigmoid was formed over a simple $β$-type AR which also possessed dispersed magnetic field structure in the photosphere. The line-of-sight photospheric magnetograms also reveal moving magnetic features, small-scale flux cancellation events near the PIL, and overall flux cancellation during the extended pre-eruption phase which suggest the role of tether-cutting reconnection toward the build-up of the flux rope. The disruption of the sigmoid proceeded with a two-ribbon eruptive M1.2 flare (SOL2013-12-07T07:29). In radio frequencies, we observe type III and type II bursts in meter wavelengths during the impulsive phase of the flare. The successful eruption of the flux rope leads to a fast coronal mass ejection (with a linear speed of $\approx$1085 km s -1 ) in SOHO/LASCO field-of-view. During the evolution of the flare, we clearly observe typical "sigmoid-to-arcade" transformation. Prior to the onset of the impulsive phase of the flare, flux rope undergoes a slow rise ($\approx$15 km s -1 ) which subsequently transitions into a fast eruption ($\approx$110 km s -1 ). The two-phase evolution of the flux rope shows temporal associations with the soft X-ray precursor and impulsive phase emissions of the M-class flare, respectively, thus pointing toward a feedback relationship between magnetic reconnection and early CME dynamics.

description: We determine the action of the Torelli group on the equivariant cohomology of the space of flat SL(2,C) connections on a closed Riemann surface. We show that the trivial part of the action contains the equivariant cohomology of the even component of the space of flat PSL(2,C) connections. The non-trivial part consists of the even alternating products of degree two Prym representations, so that the kernel of the action is precisely the Prym-Torelli group. We compute the Betti numbers of the ordinary cohomology of the moduli space of flat SL(2,C) connections. Using results of Cappell-Lee-Miller we show that the Prym-Torelli group, which acts trivially on equivariant cohomology, acts non-trivially on ordinary cohomology.

description: Патогенетическую основу поллиноза у детей и подростков составляют дифференцировка Th0 в Th2, активация Th2-клеток, увеличение продукции IL-4, IL-5, IL-13, синтеза sIgE, активация тучных клеток, базофилов, эозинофилов, последующее развитие IgE-опосредуемой аллергической реакции после повторной экспозиции с причиннозначимыми пыльцевыми аллергенами и манифестация клинических проявлений поллинозов (аллергического ринита, аллергического конъюнктивита, бронхиальной астмы). У детей и подростков, страдающих поллинозом, часто развиваются перекрестные аллергические реакции на пищевые продукты растительного происхождения. Патогенетическая фармакотерапия (антигистаминные препараты II поколения, топические глюкокортикостероиды, антилейкотриеновые препараты, деконгестанты) позволяет достичь контроля над симптомами поллиноза. Подкожная и сублингвальная АСИТ уменьшают выраженность симптомов поллинозов, снижают риск развития бронхиальной астмы и тяжелых клинических форм пыльцевой аллергии. Наиболее безопасна сублингвальная АСИТ.

description: Актуальность. Эндоназальная провокационная проба с аллергеном (ЭПП) полезна для определения аллергена - причины возникновения симптомов при аллергическом рините (АР). В настоящее время проведение ЭПП не достаточно стандартизовано, есть также сомнения в высокой безопасности пробы. Цель исследования. Оценка безопасности проведения ЭПП с аллергенами клещей домашней пыли (КДП) у детей с АР и АР в сочетании с бронхиальной астмой (БА) в клинической практике. Материалы и методы. Для анализа взяты случаи положительной ЭПП у 128 пациентов, 69 мальчиков (возраст от 5 до 15 лет, средний 9,2±1,7) и 59 девочек (возраст от 5 до 17 лет, средний 11,6±2,1), с АР или АР в сочетании с БА, с бытовой сенсибилизацией и с положительными кожными аллергопробами с КДП. Положительную ЭПП регистрировали по клиническим признакам и снижению пиковой скорости вдоха через нос на 20% от исходного и более. Протокол пробы включал введение в одну ноздрю контрольной жидкости, затем разведений аллергена в концентрации 10-4, затем 10-3, 10-2, 10-1 и цельного аллергена. Наблюдение после пробы включало контроль жалоб, нежелательных явлений, регистрацию потребовавшейся терапии и контрольную спирометрию. Результаты. В 128 случаях положительной ЭПП с КДП не было зарегистрировано серьезных нежелательных явлений, системных реакций, бронхоспазма и случаев требования терапии выше стандартной. В одном случае у пациента в возрасте 13 лет возникла осиплость голоса на введение аллергена в разведении 10-2 через 2 минуты после постановки турунды. Реакция купирована цетиризином в течение 25 минут после приема. У всех пациентов реакции на аллерген полностью разрешились в течение 30 минут наблюдения после пробы. Выводы. ЭПП с аллергенами КДП безопасна и может проводиться в амбулаторных условиях. Безопасно проведение ЭПП по отработанной градуированной методике с клинической и объективной инструментальной оценкой реакции на аллерген и наблюдением пациента после пробы.

description: The interview mostly covers Gandy’s post-retirement years in Arizona, from 2006 to the present, though it begins with a recounting of his participation in a University of Pennsylvania seminar on racial statistics and public policy organized by sociologist Tukufu Zuberi. Also discussed is Gandy’s collaboration with Chanita Hughes-Halbert on race genetics and African Americans’ health representation. Gandy explains his decision to relocate to Tucson, as well as his involvement in local politics and activism. He describes his research and writing process, in the context of his home office. The interview covers Gandy’s attempt to think through the concept of a racial class, and engagement with rational discrimination and cumulative advantage, especially in relation to his 2009 book Coming to Terms with Chance. The implications of the representation of risk, in relation to unequal life chances and policy, is extensively discussed. Gandy recounts his recent engagement with neuromarketing, and with behavioral economics.
Strategic Hub-Based Platoon Coordination under Uncertain Travel Times

description: We study the strategic interaction among vehicles in a non-cooperative platoon coordination game. Vehicles have predefined routes in a transportation network with a set of hubs where vehicles can wait for other vehicles to form platoons. Vehicles decide on their waiting times at hubs and the utility function of each vehicle includes both the benefit from platooning and the cost of waiting. We show that the platoon coordination game is a potential game when the travel times are either deterministic or stochastic, and the vehicles decide on their waiting times at the beginning of their journeys. We also propose two feedback solutions for the coordination problem when the travel times are stochastic and vehicles are allowed to update their strategies along their routes. The solutions are evaluated in a simulation study over the Swedish road network. It is shown that uncertainty in travel times affects the total benefit of platooning drastically and the benefit from platooning in the system increases significantly when utilizing feedback solutions.

description: The halo of the Milky Way provides unique elemental abundance and kinematic information on the first objects to form in the Universe, which can be used to tightly constrain models of galaxy formation and evolution. Although the halo was once considered a single component, evidence for its dichotomy has slowly emerged in recent years from inspection of small samples of halo objects. Here we show that the halo is indeed clearly divisible into two broadly overlapping structural components -- an inner and an outer halo -- that exhibit different spatial density profiles, stellar orbits and stellar metallicities (abundances of elements heavier than helium). The inner halo has a modest net prograde rotation, whereas the outer halo exhibits a net retrograde rotation and a peak metallicity one-third that of the inner halo. These properties indicate that the individual halo components probably formed in fundamentally different ways, through successive dissipational (inner) and dissipationless (outer) mergers and tidal disruption of proto-Galactic clumps.

Molding God’s children : the history of curriculum in Christian schools rooted in Dutch Calvinism
Creators: name: Van Brummelen, Harro W.
Publisher: name: University of British Columbia
Year: 2010

description: Dutch Calvinists founded and still give key educational leadership to most of the 272 American and 110 Canadian member schools of Christian Schools International. The schools, locally controlled by parent associations, have attempted to implement the claim that Christian beliefs should affect their total program. Since 1910, therefore, the movement has published curriculum materials in various subject areas and implemented these in many of its schools. This study investigates the schools' Dutch background, their beginnings in nineteenth century America, their Americanization between 1890 and 1920, their "bulwark" mentality during the inter-war years, and their quest for purpose since World War II. It discusses curriculum issues at the national, regional and local levels, taking into account the rapid Canadian growth since 1950. Particularly, it focuses on how far the schools have realized their goals through distinctive curricula. Two divergent though overlapping strains of Calvinist thought—a monastic view attempting to protect children from a secular society and an integrationist one intending children to become participants in a Christian cultural transformation of North American society—were rooted in the supporters' religious and social backgrounds. While both views stressed the teaching of Biblical studies, Calvinist moral values and Christian interpretations of literature and historical events, their differing emphases caused unresolved curricular tensions, especially in Canada in the 1960s and 1970s, about both content choice and pedagogy. The immigrants' desire for social and economic assimilation advanced the schools' integration into the mainstream of North American education. In the U.S., particularly after 1910, their striving for educational excellence and their conservative faith in American patriotism, pragmatism and progress abetted the schools' dependence on public school courses and materials. The various public education curriculum orientations also found somewhat modified parallels in Christian schools. The homogenizing influence of the modern state, moreover, affected the schools through curriculum guides, textbook authorizations, and post-secondary entrance requirements. By 1977, when many of the schools were losing some of their religious and cultural cohesiveness, they had not yet demonstrated the possibility of fully implementing their leaders' vision of Biblical, Christian principles permeating the schools' total program.

Andreev Transport through Side-Coupled Double Quantum Dots

description: We study the transport through side-coupled double quantum dots, connected to normal and superconducting (SC) leads with a T-shape configuration. We find, using the numerical renormalization group, that the Coulomb interaction suppresses SC interference in the side dot, and enhances the conductance substantially in the Kondo regime. This behavior stands in total contrast to a wide Kondo valley seen in the normal transport. The SC proximity penetrating into the interfacial dot pushes the Kondo clouds, which screens the local moment in the side dot, towards the normal lead to make the singlet bond long. The conductance shows a peak of unitary limit as the cloud expands. Furthermore, two separate Fano structures appear in the gate-voltage dependence of the Andreev transport, where a single reduced plateau appears in the normal transport.

 Material examined: Praslin, Mt. Cabris, 11 specimens and 5 eggs, some of which with fully developed embryo, in a sample of mosses from soil; North Island, 2 specimens and 2 eggs in a sample of leaf-litter of Calophyllum sp.
 Macrobiotus madegassus
 This is the second record of the species, therefore we think it opportune to add some details to the description of Maucci (1993). We compared our specimens with one paratype kindly loaned by the Museo Civico di Storia Naturale di Verona, and we noted that, different from the description of Maucci, the cuticle has circular and elliptical pores. The buccal tube is long and narrow, the dorsal transverse ridges of the buccal armature are joined forming a thin, unique arc; the stylet supports are inserted on the buccal tube far away from the pharyngeal bulb (pt = about 71). The pharyngeal apophyses are very developed; the microplacoid small. The dimensions of some structures are provided in Table 1. The eggs, of hufelandi type have 30–34 processes around the circumference and 125–145 in the hemisphere. The processes are up to 5.5 µm high with a basal diameter 5.3–6 µm long; diameter of the terminal disc up to 3.3 µm. The egg shell, between the processes, has a dense reticular design with very small meshes (Maucci (1993) used the expression “with regular pores”); the meshes around the processes are not larger than the others and therefore, as also Maucci (1993) specified, the bases of the processes do not have a ring of traits particularly evident.

description: We propose a correction to the coefficient of nuclear-spin diffusion by a factor $1/\sqrt{1-\overline{p}^{2}}$, where $\overline{p}$ is the average nuclear-spin polarization. The correction, derived by extending the Lowe-Gade theory to low-temperature cases, implies that transportation of nuclear magnetization through nuclear-spin diffusion accelerates when the system is hyperpolarized, whereas for low-polarization the correction factor approaches unity and the diffusion coefficient coincides with the conventional diffusion coefficient valid in the high-temperature limit. The proposed scaling of the nuclear-spin diffusion coefficient can lead to observable effects in the buildup of nuclear polarization by dynamic nuclear polarization.
