description: Long-lived (symmetry protected) hyperpolarized spin states offer important new opportunities (for example, in clinical MR imaging), but existing methods for producing these states are limited by either excess energy dissipation or high sensitivity to inhomogeneities. We extend recent work on continuous-wave irradiation of nearly-equivalent spins (spin-lock induced crossing) by designing composite pulse and adiabatic shaped-pulse excitations which overcome the limitations. These composite and adiabatic pulses differ drastically from the traditional solutions in two-level systems. We also show this works in chemically equivalent spin pairs, which has the advantage of allowing for polarization transfer from and to remote spins. The approach is broadly applicable to systems where varying excitation strength induces an avoided crossing to a dark state, and thus to many other spectroscopic regimes.

description: The visually close binary system HD25811 is analyzed to estimate its physical and geometrical parameters in addition to its spectral type and luminosity class. The method depends on obtaining the best fit between the entire observational spectral energy distribution (SED) of the system and synthetic SEDs created by atmospheric modeling of the individual components, consistent with the system's modified orbital elements. The parameters of the individual components of the system are derived as: $T_{\rm eff}^{\rm a} =6850\pm50$\,K, $T_{\rm eff}^{\rm b} =7000\pm50$\,K, log $g_{\rm a}=4.04\pm0.10$, log $g_{\rm b}=4.15\pm0.10$, $R_{\rm a}=1.96\pm0.20$\,R$_{\odot}$, $R_{\rm b}=1.69\pm0.20$\,R$_{\odot}$, $M_{va}=1.97\pm0.20$, $M_{vb}=2.19\pm0.20$, $L_a= 7.59\pm0.70 L_\odot, L_b= 6.16\pm0.70 L_\odot$ with dynamical parallax $π(\textrm{mas})=5.095\pm 0.095$. The analysis shows that the system consists of a $1.55M_{\odot}$ F2 primary star and a less evolved $1.50M_{\odot}$ F1 secondary subgiant star with ages around 2 Gy formed by fragmentation. Synthetic magnitudes of both components were calculated under Johnson-Cousins, Strömgren, and Tycho photometrical systems.

description: Superhydrophobic Cassie textures with trapped gas bubbles reduce drag, by generating large effective slip, which is important for a variety of applications that involve a manipulation of liquids at the small scale. Here we discuss how the dissipation in the gas phase of textures modifies their friction properties. We propose an operator method, which allows us the mapping of the flow in the gas subphase to a local slip boundary condition at the liquid/gas interface. The determined uniquely local slip length depends on the viscosity contrast and underlying topography, and can be immediately used to evaluate an effective slip of the texture. Besides superlubricating Cassie surfaces our approach is valid for rough surfaces impregnated by a low-viscosity 'lubricant', and even for Wenzel textures, where a liquid follows the surface relief. These results provide a framework for the rational design of textured surfaces for numerous applications.

description: BiFeO$_3$ (BFO) shows both ferroelectricity and magnetic ordering at room temperature but its ferromagnetic component, which is due to spin canting, is negligible. Substitution of transition-metal atoms such as Co for Fe is known to enhance the ferromagnetic component in BFO. In order to reveal the origin of such magnetization enhancement, we performed soft x-ray absorption spectroscopy (XAS) and soft x-ray magnetic circular dichroism (XMCD) studies of BiFe$_{1-x}$Co$_x$O$_3$ ({\it x} = 0 to 0.30) (BFCO) thin films grown on LaAlO$_3$(001) substrates. The XAS results indicated that the Fe and Co ions are in the Fe$^{3+}$ and Co$^{3+}$ states. The XMCD results showed that the Fe ions show ferromagnetism while the Co ions are antiferromagnetic at room temperature. The XAS and XMCD measurements also revealed that part of the Fe$^{3+}$ ions are tetrahedrally co-ordinated by oxygen ions but that the XMCD signals of the octahedrally coordinated Fe$^{3+}$ ions increase with Co content. The results suggest that an impurity phase such as the ferrimagnetic $γ$-Fe$_2$O$_3$ which exists at low Co concentration decreases with increasing Co concentration and that the ferromagnetic component of the Fe$^{3+}$ ion in the octrahedral crystal fields increases with Co concentration, probably reflecting the increased canting of the Fe$^{3+}$ ions.

description: The latest volume in the Language Planning and Policy series, co-edited by Baldauf and Kaplan, deals with three Latin American countries, Ecuador, Mexico, and Paraguay, which, while not geographically close, do share several key factors in relation to their language situation and corresponding governmental policy. Previous books in this series on Africa, Asia, and Europe have dealt with similar issues of linguistic diversity and political context, yet the study of these Latin American countries offers the unique and distinguishing characteristic of one official language impacting three separate countries. The objective of these studies, and in fact the series, is to address roughly two-dozen questions that bring to light the nature of language in these countries. The editors organize the questions into four sections: language profile, language spread, language policy and planning, and language maintenance and prospects. The first section, language profile, includes not only general information on the languages, but also tables with the number of speakers as well as speaker distribution maps. Language spread, the second section, includes information on education, the role of media, and the role of immigration. The next section, language policy and planning, focuses on the topic with special attention paid to the historical background. Finally, the language maintenance and prospects section is designed to summarize the transmission of these languages and their probable future direction.

Efficiency and dissipation in a two-terminal thermoelectric junction, emphasizing small dissipation

description: The efficiency and cooling power of a two-terminal thermoelectric refrigerator are analyzed near the limit of vanishing dissipation (ideal system), where the optimal efficiency is the Carnot one, but the cooling power then unfortunately vanishes. This limit, where transport occurs only via a single sharp electronic energy, has been referred to as "strong coupling" or "the best thermoelectric". It follows however, that "parasitic" effects that make the system deviate from the ideal limit, and reduce the efficiency from the Carnot limit, are crucial for the usefulness of the device. Among these parasitics, there are: parallel phonon conduction, finite width of the electrons' transport band and more than a single energy transport channel. In terms of a small parameter characterizing the deviation from the ideal limit, the efficiency and power grow linearly, and the dissipation {\em quadratically}. The results are generalized to the case of broken time-reversal symmetry, and the major nontrivial changes are discussed. Finally, the recent universal relation between the thermopower and the asymmetry of the dissipation between the two terminals is briefly discussed, including the small dissipation limit.

Co-construction of Word Search Activities in Native and Non-native Speaker Interaction

Subjects: Conversation analysis

description: This paper examines the co-construction of word search activities between native and non-native speakers of English. Word searching occurs when two interlocutors use joint resources to retrieve a word that is alluding one of the interlocutors in conversation. Word searches are highly prevalent in interaction, often becoming a central activity in non-native discourse. The focus of this article is twofold: first, on the sequential organization of the word search activity, and second, on the public structure of word searches. Using video recordings of English tutoring sessions and social gatherings of native and non-native speakers of English, the detailed practice of word searching was analyzed in this study. It examines the interactional process through which a distributed responsibility of participants for sequential coherence, meaning, and events is co-constructed (Jacoby & Ochs, 1995). This article argues that a word search activity is a social action, and interactions between native and non-native speakers of English demonstrate the ways through which participants coordinate this sequential and public action.

description: We demonstrated that by using a pump field with non-zero orbital angular momentum (OAM) in the polarization self-rotation squeezing process it is possible to generate a squeezed vacuum optical field with the matching OAM. We found a similar level of maximum quantum noise reduction for a first-order Laguerre-Gaussian pump beam and a regular Gaussian pump beam, even though the optimal operational conditions differed in these two cases. Also, we investigated the effect of self-defocusing on the level of the vacuum squeezing by simultaneously monitoring the minimum quantum noise level and the output beam transverse profile at various pump laser powers and atomic densities, and found no direct correlations between the increased beam size and the degree of measured squeezing.

Covariant Differential Identities and Conservation Laws in Metric-Torsion Theories of Gravitation. II. Manifestly Generally Covariant Theories

description: The present paper continues the work of the authors [arXiv:1306.6887 [gr-qc]]. Here, we study generally covariant metric-torsion theories of gravity presented more concretely, setting that their Lagrangians are \emph{manifestly} generally covariant scalars. It is assumed that Lagrangians depend on metric tensor, curvature tensor, torsion tensor and its first and second covariant derivatives, besides, on an arbitrary set of other tensor (matter) fields and their first and second covariant derivatives. Thus, both the standard minimal coupling with the Riemann-Cartan geometry and non-minimal coupling with the curvature and torsion tensors are considered. The studies and results are as follow. (a) A physical interpretation of the Noether and Klein identities is examined. It was found that they are the basis for constructing equations of balance of energy-momentum tensors of various types (canonical, metrical and Belinfante symmetrized). The equations of balance are presented. (b) Using the generalized equations of balance, new (generalized) manifestly generally covariant expressions for canonical energy-momentum and spin tensors of the matter fields are constructed. In the cases, when the matter Lagrangian contains both the higher derivatives and non-minimal coupling with curvature and torsion, such generalizations are non-trivial. (c) The Belinfante procedure is generalized for an arbitrary Riemann-Cartan space. (d) A more convenient in applications generalized expression for the canonical superpotential is obtained. (e) A total system of equations for the gravitational fields and matter sources are presented in the form more naturally generalizing the Einstein-Cartan equations with matter. This result, being a one of more important results itself, is to be also a basis for constructing physically sensible conservation laws and their applications.

description: These Sessional Clippings books cover the period 1891 to 1972, and include newspaper accounts written by various legislative reporters who covered debates occurring in the British Columbia Legislative Assembly. Transcripts of debates of the Legislative Assembly (Hansard) were not published in B.C. until 1970; hence these "Sessional Clipping Books" augment the "Journals", the record of daily proceedings of the Legislative Assembly. Selected clippings from various newspapers including the Vancouver Sun, the Vancouver Province, the Colonist, and the Times newspapers, relating to the newspaper reports concerning activities of the Legislature. The original sessional clippings books comprise 351 ledger size print volumes, held at the Legislative Library in Victoria BC. The print volumes were microfilmed onto 26 reels in 1977 under a Tri University Libraries (TRIUL) project by Precision Micrographic Services (Vancouver, B.C.), with the permission of the Legislative Library, Victoria, British Columbia. This digital collection was created by scanning the 26 microfilm reels.

description: Spin-density-functional calculations of tip-suspended gold chains, with molecular oxygen, or dissociated oxygen atoms, incorporated in them, reveal structural transitions for varying lengths. The nanowires exhibit enhanced strength for both oxygen incorporation modes, and upon stretching tip atoms join the wire. With incorporated molecular oxygen the wire conductance is about 1(2e2/h), transforming to an insulating state beyond a critical length. The nanowire conductance with embedded oxygen atoms is low, 0.2 (2e2/h), and it develops magnetic moments localized on the oxygens and the neighboring Au atoms.

description: Thermal photons detected by PHENIX can provide information about the temperature of a possible QGP produced at RHIC. We present a new method identifying photons by measuring e+e− pairs from photon conversions in the beam pipe. The conversion pairs acquire an apparent mass and a characteristic orientation relative to the magnetic field direction. These properties can be used to distinguish conversion pairs from Dalitz decays.

description: This paper provides a comprehensive review of the literature on the discourse analysis of spoken interaction in the family context. Specific aspects of family discourse are discussed, including the co-construction of identity, the specific roles and identities of family members, and the patterns of interaction found in the discourse. Since gender is an important aspect of family roles, an overview of the research on gender and spoken interaction is included. The concepts of framing and power, as they relate to family interaction are also discussed given the salience researchers have attached to these concepts. This is followed by a review of the literature on language and identity, including the co-construction of identity in interaction, and discourse analysis studies on particular family member roles and family identity. Discourse patterns specific to family interaction are discussed in the last section. The review concludes that although discourse analysis research on family talk has shed light on family-specific patterns of interaction, it has nevertheless focused on a narrowly defined concept of what constitutes a family and has largely been based on short-term data collection.

Slow-roll parameters and perturbation parameters are presented for this model. We find the general conditions which are required for this model to be realizable in slow-roll approximation. We also develop our model in the context of intermediate and logamediate scenarios which are exact solutions of inflationary field equation in the Einstein theory. General expressions of slow-roll parameters, tensor-scalar ratio and scalar spectral index are presented in terms of inflaton field for these two cases. Our model is compatible with recent observational data from Planck satellite.

description: The purpose of this research was three-fold. Firstly, it was conducted in order to acquaint the author with the technique of measuring the vertical and horizontal components of the distorted earth's magnetic field and with the problems which arise during the course of a magnetic survey. Secondly, it was conducted in order to acquaint the author with the usefulness of the magnetometer as an aid to the solution of structural geology problems. Lastly, it was conducted in the hope that a contribution would be made to geologic knowledge in the field of structural geology.

Two areas were chosen for investigation. The Los Angeles Basin Area was chosen because it afforded an opportunity to study a large geologic feature, complicated by faults, about which much is well known. The second area, Antelope Valley, in the Mojave Desert, was chosen because several faults of great displacements are known, or supposed, to exist in the area and because a large portion of the area is covered by aluvium, thus affording opportunity to investigate an area about which little is known.

The Calculated Flight Path of the U.S.S. Macon

Subjects: Aeronautical Engineering

description: These calculations are concerned with the flight path of the Macon after the loss of the upper fin and the deflation of the three after gas cells.  Taking into account the actual flight conditions, the question was raised whether the ship would rise to an altitude of 4800 feet.  For at this altitude, which the record shows was actually reached, the ship had exceeded pressure height by about 2000'.  In going over pressure height, the ship loses approximately 3% of her lift for every 1000 feet.  Hence 4800 feet corresponds to a heaviness of nearly 11 tons.  It was felt that if this additional heaviness could have been avoided, the ship might have been flown safely in spite of the loss of some 20 tons of lift from the three after cells.  The calculations were undertaken to determine whether the aerodynamic and aerostatic forces alone were sufficient to force the ship up to 4800 feet or whether there were external forces acting, i. e. gust forces.

description: Graphene quantum dots (GQDs) are a new class of fluorescent materials which have attracted attention due to their unique, optoelectronic and spectroscopic properties. Such Q-dots of graphene may be prepared using different organic resources and carbonization from small aromatic molecules or polymers. The GQDs possess a graphene core and attached functional groups. The fluorescence is controlled by both the graphene core and the surrounding chemical groups and is sensitive to pH and presence of other ions. GQDs can be used as fluorescent probes for sensing different types of ions such as metals and explosives and for the chemical characterisation of molecules and ions, A facile, low-cost, and microwave-assisted synthesis process of GQDs was developed by using paper-ash as a precursor, obtained after burning a white photocopier-paper. The photoluminescence from the as-synthesized GQDs is in the green range (500 nm), when excited with a source at λex=365 nm. After optimizing the experimental conditions, a sensitive sensing medium was developed to detect explosives and free residual metal-ions in the environment, based on fluorescence quenching of GQDs. Fourteen different types of metal ions—namely, Cu2+, Mg2+, Zn2+, Fe2+, Cd2+, Al3+, Hg2+, K+, Ag+, Na+, Cr3+, Ba2+, Ce3+, Pb2+ and six different types of explosives—namely, trinitrophenol (TNP), trinitrotoluene (TNT), cyclotrimethylenetrinitramine (RDX), 4-nitrophenol (4-NP), 2,4-dinitrotoluene (2,4-DNT), and 2,4-dinitrophenol (2,4-DNP) were analysed for sensing experiments. Photoluminescence of as-synthesized GQDs was observed as a function of pH in the (2-9) range. It was found that GQDs adjusted at pH 6 (using HCl buffer), showed the maximum quantum yield (QY) of ~38.2%, hence, accounted for all the sensing experiments. The as-synthesized GQDs, as a sensing system is most sensitive for Cu2+ ion and 2,4-DNP with a detection limit of 0.62 µM and 0.50 µM, respectively.

description: Through the close analysis of and critical discussion surrounding a fifth-grade dual-immersion classroom, Hadi-Tabassum explores the often inequitable role of language in the classroom. In her critical ethnographic study entitled Language, Space and Power: A Critical Look at Bilingual Education, young learners of both Spanish and English are observed as they engage themselves in various classroom tasks and metalinguistic discussions. Based on the ethnographic observation, parallels are drawn between such concepts as identity, language, and power. As a result, Hadi-Tabassum is able to explore what she deems the third space, a space where awareness focuses upon a desire to overcome linguistic borders and boundaries. Through an emphasis upon discourse rather than language acquisition, the author shows how conflicts over language use and the mediation of these conflicts arise.
title: Field report on GNSS surveys of the Top of the South Island Network in 2018 (TOPS2018)
Creators: name: Hart, Rory J.A.
name: Palmer, Neville G.
Publisher: name: GNS Science
Year: 2019

description: During a 28-day period between January and April 2018, a combined team from GNS Science and Land Information New Zealand re-measured a network of 108 geodetic survey stations using Global Navigation Satellite System (GNSS) methods throughout the Upper South Island of New Zealand. This Top of the South Island campaign (TOPS2018) covers an area from Cheviot in the south to Cape Farewell in the north and is intended to repeat previous comprehensive GNSS surveys of the network following the Kaikoura 2016 earthquake. This report documents the field operations of the TOPS2018 resurvey. It describes the logistics of the campaign, the sites occupied, and the data collected. (auth)

description: Replacing configurations of points by configurations of tubular neighbourhoods (or discs) in a manifold, we are able to define a natural scanning map that is equivariant under the action of the diffeomorphism group of the manifold. We also construct the so-called power set map of configuration spaces diffeomorphism equivariantly. Combining these two constructions yields stable splittings in the sense of Snaith and generalisations thereof that are equivariant. In particular one deduces stable splittings of homotopy orbit spaces. As an application the homology injectivity is proved for diffeomorphism of manifolds that fix an increasing number of points. Throughout we work with configurations spaces with labels in a fibre bundle.

description: This paper deals with the dynamics of a shearfree charged radiating collapse in modified Gauss-Bonnet gravity. The field equations for shearfree spherical interior geometry of a charged dissipative star are formulated. To study the dynamical behavior of collapsing matter, we derive the dynamical as well as transport equations. We conclude that the gravitational force in modified Gauss-Bonnet gravity is much stronger as compared to general relativity which implies the increase in the rate of collapse. Finally, we study the effect of charge on the dynamics of collapse.

Report on advances in beam diagnostics for 3rd generation light sources
Creators: name: ARIES WP8 Members
Publisher: name: Zenodo
Year: 2021

description: Section 5 of this Report covers the subject of Deliverable 8.3 (Advances in beam diagnostics for 3rd generation light sources). Sections 5.1 to 5.3 summarize the three International Workshops organised on this specific subject, and Section 5.4 presents some general conclusions on the status of this field and on possible future developments. In the Appendix, detailed descriptions of the three Workshops concerned are given.
 ARIES Work Package 8 aims for transfer of knowledge and standardisation of equipment across the European Research Infrastructures making use of beam instrumentation and diagnostics for particle accelerators. In total, 11 International Workshops were organized with 32 to 239 delegates (maximum for a remote workshop). Financial support for visits of scientists was covered in total for eight weeks.
 While in the initial Work Plan it was foreseen to produce as a Deliverable four separated Reports, one for each of the Tasks/sub-sets of diagnostic equipment, during the execution of the project it turned out the number of intercorrelations and crossed references between the four areas was so large that it was more effective to produce a single report, with four Sections each devoted to one of the Tasks/Deliverables.

Disinventing and Reconstituting Languages

description: Those familiar with Pennycook’s previous works such as English and the Discourses of Colonialism (1998) or Critical Applied Linguistics: A Critical Introduction (2001) will not be surprised to learn that this latest volume, co-edited with Makoni and titled Disinventing and Reconstituting Languages, challenges many orthodoxies related to the role of English in the world and the nature of language. As far back as his 1994 book, The Cultural Politics of English as an International Language, Pennycook has been contesting the view that the global spread of English has been a natural, neutral, and beneficial process and has argued against fixation on language as an a priori ontological system in favor of focus on “language use as a social, cultural, and political act” (Pennycook, 1994, p. 29). It is not difficult to imagine that the editors’ collaboration on this volume was inspired in part by a critique Makoni offered of Pennycook’s Critical Applied Linguistics suggesting that in the absence of concrete strategies for engaging and collaborating with local communities, “Critical Applied Linguistics runs the danger of being hegemonic to the very communities it seeks to serve” (Makoni, 2003, p. 135). Disinventing and Reconstituting Languages is also a natural extension of Makoni’s plenary contribution at the 2004 American Association of Applied Linguistics conference in Portland where he proposed a vision of applied linguistics grounded less in an Anglo-American or Western world view, but having greater relevance to a variety of sociolinguistic contexts (Makoni, 2005). Following a forward by Ofelia García, the book is divided into 10 chapters covering the following three areas: the socio-political contexts from which current understandings of language have grown, the way current conceptions of language have limited development of a more nuanced understanding of how people communicate, and the pedagogical implications a language disinvention and reconstitution process might have.

description: These Sessional Clippings books cover the period 1891 to 1972, and include newspaper accounts written by various legislative reporters who covered debates occurring in the British Columbia Legislative Assembly. Transcripts of debates of the Legislative Assembly (Hansard) were not published in B.C. until 1970; hence these "Sessional Clipping Books" augment the "Journals", the record of daily proceedings of the Legislative Assembly. Selected clippings from various newspapers including the Vancouver Sun, the Vancouver Province, the Colonist, and the Times newspapers, relating to the newspaper reports concerning activities of the Legislature. The original sessional clippings books comprise 351 ledger size print volumes, held at the Legislative Library in Victoria BC. The print volumes were microfilmed onto 26 reels in 1977 under a Tri University Libraries (TRIUL) project by Precision Micrographic Services (Vancouver, B.C.), with the permission of the Legislative Library, Victoria, British Columbia. This digital collection was created by scanning the 26 microfilm reels.

description: We present a new approach to calculation of anomalous dimensions in the framework of $ε$-expansion and renormalization group method. This approach allows one to skip the calculation of renormalization constants and express anomalous dimensions in terms of renormalized diagrams, which are presented in a form suitable for numerical calculations. This approach can be easily automated and extended to a wide range of models. The power of this approach is illustrated on 5 loop calculations of beta-function and anomalous dimensions in $ϕ^4$ model.

description: The volume, Motivation, Language Attitudes and Globalisation: A Hungarian Perspective, written by Dörnyei, Csizér, and Németh, presents the results of a large survey on motivation in second language learning from over 13,000 Hungarian foreign language learners collected in three successive stages during 1993, 1999, and 2004. The objectives of this book were to provide a quantitative statistical analysis on the significance of the relationship between the socio-political changes in Hungary and the variety of interests among Hungarians in learning five foreign languages: English, German, French, Italian, and Russian. The informants were young teenagers selected nationwide and surveyed during an eventful, historical time in the country, that is, the 12-year transitional period when the nation went from restrained communism to an open, Western-style democracy. The fact that Hungary faced many difficult obstacles in a plethora of areas in its drive towards European Union membership makes this study particularly interesting. The various national, political, social, and personal motives of the Hungarians to choose and learn particular foreign languages are analyzed in this volume.
Characteristics of Braked, Locked and Free-Wheeling Two- and Three-Bladed  Propellers

description: The use of multi-engined aircraft has introduced the problem of aircraft performance when one or more power units have either become unusable or voluntarily shut down during cruising flight.  If the use of the engine is to be discontinued because of mechanical failure, the desirable procedure is obviously to stop it altogether, so as to prevent possible destruction to the engine.  This can be accomplished by locking the propeller, by a free-wheeling arrangement, or by feathering a variable pitch propeller.  If the use of the engine is to be discontinued merely to reduce fuel consumption, the propeller may be allowed to turn the engine, in which case the propeller is braked by a torque equal to the friction of the engine.

Another recent development connected with braked propellers is the fact that the variable pitch propeller now offers the possibility of using the large increment in drag at low blade angles of braked and free-wheeling propellers for reduction in landing speed or landing run of clean, highly powered, multi-engined aircraft.

It was the purpose of the present investigation to provide information not already made available by researches listed under the references at the end of this paper.  Therefore the following thesis will be concerned chiefly with the three-bladed propeller and its effect on airplane characteristics, the two-bladed propeller being used principally for comparison purposes with other available data.  The tests were performed at model scale, but their acceptance as applicable to full scale is supported by the favorable comparisons made in Reference 5.
