Radiata : an economic breeding objective : the definition of an economic breeding objective for plantation radiata pine grown to produce timber flitch and newsprint and an investigation of some aspects related to short-rotation breeding in general using plantation eucalypts as an example
Creators: name: Chambers, PGS
Publisher: name: University Of Tasmania
Year: 2023

description: An economic breeding objective was defined for unpruned radiata pine grown to produce structural grade timber flitch and high brightness newsprint from thermomechanical pulp (TMP) in Australia. A production enterprise model was developed including all sources of income (sale of flitch and newsprint) and costs (including growing, harvesting, transporting and mill processing components). The enterprise, as modelled, was shown to be profitable (Profitability Index 19.9%, assuming a discount rate of 5%). The majority of wood volume was assumed to be utilised to produce high brightness newsprint (77% by volume), with only 23% used to produce rough green flitch. The effect of future changes in growth, bark volume, stem sweep, stem taper, branch quality, timber strength, basic density, tracheid length, tracheid coarseness and wood brightness (breeding objective traits) on the profitability of this production enterprise was modelled by defining profit functions relating each of these traits to the economics of each stage of production. Sensitivity analysis was employed throughout this process to examine which assumptions were driving profitability, and identify any that may need verification. For each trait an economic weight was estimated as the incremental Profitability Index associated with a unit increa, se in each trait. Basic density, mean tracheid length and wood brightness were demonstrated as having a major effect on the production of high brightness newsprint from TMP. Growth, as expected, had a large impact on the cost of growing a plantation, however was predicted to be only of moderate to low importance in increasing enterprise profitbability overall. Branch index was shown to have a major impact on the profitability of the flitch production line of the enterprise. Bark volume, stem sweep, stem taper and tracheid coarseness appeared to have a very low impact on production system profitability. However, the importance of stem sweep and stem taper as well as branch index and timber strength are likely to become more important if the enterprise increases its production ratio of flitch to newsprint. An investigation into multi-trait selection strategies clearly demonstrated the dominance of basic density as a selection trait on enterprise profitability. The assessment of wood and tracheid properties is much more costly than assessment of growth and form traits. However it was demonstrated that the gains predicted from individual-tree selections compared with selection based on family-means for basic density and tracheid length are significant and well worth the additional associated cost.
title: Restructuring of the Axon Initial Segment in Mouse Models of Neurodevelopmental Disorders

description: Neurodevelopmental disorders (NDDs) affect more than 36% of children in countries with low- and middle- incomes (Boivin, 2015; McCoy, 2016). Interestingly, these heterogeneous disorders share a high incidence of epileptic seizures, suggesting a shared pathology. Seizures result when neuronal firing activity becomes disturbed and neurons fire excessively or in unregulated patterns. A key site in the control of neuronal firing patterns is the axon initial segment (AIS), where the local density of proteins and the morphology of the AIS in part determine the firing of neurons. We hypothesized that a disruption in the morphology and/or composition of the AIS can lead to the phenotypes seen in neurodevelopmental disorders, including seizures. To study this possibility, we performed morphological analyses of the AIS of cortical pyramidal neurons in mouse models of NDDs with a high incidence of epilepsy (Gabra2-1 and Mecp2+/-). Our results reveal morphological changes at the AIS of both, Gabra2-1 and Mecp2+/- mice, when compared to wild-type mice. Understanding neuropathological changes leading to these heterogeneous disorders will increase knowledge of the general underlying mechanisms thus contributing to the development of better therapies.

description: We present the topological solutions of Einstein gravity in the presence of a non-Abelian Yang-Mills field. In ($n+1$) dimensions, we consider the $So(n(n-1)/2-1,1)$ semisimple group as the Yang-Mills gauge group, and introduce the black hole solutions with hyperbolic horizon. We argue that the 4-dimensional solution is exactly the same as the 4-dimensional solution of Einstein-Maxwell gravity, while the higher-dimensional solutions are new. We investigate the properties of the higher-dimensional solutions and find that these solutions in 5 dimensions have the same properties as the topological 5-dimensional solution of Einstein-Maxwell (EM) theory although the metric function in 5 dimensions is different. But in 6 and higher dimensions, the topological solutions of EYM and EM gravities with non-negative mass have different properties. First, the singularity of EYM solution does not present a naked singularity and is spacelike, while the singularity of topological Reissner-Nordstrom solution is timelike. Second, there are no extreme 6 or higher-dimensional black holes in EYM gravity with non-negative mass, while these kinds of solutions exist in EM gravity. Furthermore, EYM theory has no static asymptotically de Sitter solution with non-negative mass, while EM gravity has.

description: Recently, it has been shown that electrons and positrons from dark matter (DM) annihilations provide an excellent fit to the Fermi, PAMELA, and HESS data. Using this DM model, which requires an enhancement of the annihilation cross section over its standard value to match the observations, we show that it immediately implies an observable level of gamma-ray emission for the Fermi telescope from nearby galaxy clusters such as Virgo and Fornax. We show that this DM model implies a peculiar feature from final state radiation that is a distinctive signature of DM. Using the EGRET upper limit on the gamma-ray emission from Virgo, we constrain the minimum mass of substructures within DM halos to be > 5x10^-3 M_sun -- about four orders of magnitudes larger than the expectation for cold dark matter. This limits the cutoff scale in the linear matter power spectrum to k < 35/kpc which can be explained by e.g., warm dark matter. Very near future Fermi observations will strongly constrain the minimum mass to be > 10^3 M_sun: if the true substructure cutoff is much smaller than this, the DM interpretation of the Fermi/PAMELA/HESS data must be wrong. To address the problem of astrophysical foregrounds, we performed high-resolution, cosmological simulations of galaxy clusters that include realistic cosmic ray (CR) physics. We compute the dominating gamma-ray emission signal resulting from hadronic CR interactions and find that it follows a universal spectrum and spatial distribution. If we neglect the anomalous enhancement factor and assume standard values for the cross section and minimum subhalo mass, the same model of DM predicts comparable levels of the gamma-ray emission from DM annihilations and CR interactions. This suggests that spectral subtraction techniques could be applied to detect the annihilation signal.

description: The preparation of ordered macroporous SiCN ceramics has attracted significant interest and is an attractive area for various applications, e.g., in the fields of catalysis, gas adsorption, or membranes. Non-oxidic ceramics, such as SiCN, own a great stability based on the covalent bonds between the containing elements, which leads to interesting properties concerning resistance and stability at high temperature. Their peculiar properties have become more and more important for a manifold of applications, like catalysis or separation processes, at high temperatures. Within this work, a feasible approach for the preparation of ordered porous materials by taking advantage of polymer-derived ceramics is presented. To gain access to free-standing films consisting of porous ceramic materials, the combination of monodisperse organic polymer-based colloids with diameters of 130 nm and 180 nm featuring a processable preceramic polymer is essential. For this purpose, the tailored design of hybrid organic/inorganic particles featuring anchoring sites for a preceramic polymer in the soft shell material is developed. Moreover, polymer-based core particles are used as sacrificial template for the generation of pores, while the preceramic shell polymer can be converted to the ceramic matrix after thermal treatment. Two different routes for the polymer particles, which can be obtained by emulsion polymerization, are followed for covalently linking the preceramic polysilazane Durazane1800 (Merck, Germany): (i) Free radical polymerization and (ii) atom transfer radical polymerization (ATRP) conditions. These hybrid hard core/soft shell particles can be processed via the so-called melt-shear organization for the one-step preparation of free-standing particle films. A major advantage of this technique is the absence of any solvent or dispersion medium, enabling the core particles to merge into ordered particle stacks based on the soft preceramic shell. Subsequent ceramization of the colloidal crystal films leads to core particle degradation and transformation into porous ceramics with ceramic yields of 18–54%. © 2019 by the authors.
Illuminating musical lifeworlds: phenomenological narratives of the musical life worlds of five senior secondary school students
Creators: name: Cleaver, DM
Publisher: name: University Of Tasmania
Year: 2023

description: This study investigates the musical lifeworlds of five musically dedicated senior secondary high school students in order to explicate meaning structures within their 'musical ways of being'. These structures illuminate the participants' musical lives as they are 'lived' and each idiosyncratic and unique relationship with music. While the study illuminates broad features of the way 'musical lives are lived' it also highlights two specific lifeworld realms. The first is the realm of lived musical experiences that are described as deeply felt, formative, trans formative or epiphanic. Interpretation of these experiences provides insight into the ways that the participants had commenced musical lives. The second is the realm of lived experience with different types of music learning processes. Illuminating music teaching and learning processes from the perspective of each student is designed to contribute to the ongoing dialogue and discussion of music's place in formal institutional settings and informal, student initiated communities of practice. Data were generated from interviews with the participants, their parents and music teachers, and also from observations of musical performances, researcher field notes and reflexive journal entries. A 're-storying' process was then conducted using narrative analyses and syntheses and phenomenological interpretation. The re-storied research texts were then structured and presented as composite 'portraits' of each participant. The project promotes narrative and phenomenological 'ways of thinking'about music, music experience and processes of inquiry. I have explored a pragmatic, embodied and situated experience of narrative and phenomenological 'ways of thinking' rather than operating from a priori principles and abstract theories about them. This pragmatic engagement is made visible by the insertion of vignettes, at strategic points, of my situated, lived experiences and learning processes with being a narrative and phenomenological thinker. The findings suggest that by illuminating the essential mearungs within individual musical lifeworlds, music may be perceived not as a thing, but an active process and a socially mediated, integrated structure of self. Sensitivity to and empathy with the ways students live musical lives may assist educators to achieve situational appropriateness whilst teaching. Understanding the ways that life and music are inseparable will help to counter the alienating tendency in Western music education to view music as an autonomous aesthetic object that is independent of the experiencer. The findings suggest that music educators engage in 'pedagogical self-transformation' by adopting a narrative and phenomenological stance. This transformation, I argue, promotes empathy where educators are primarily engaged as 'enhancers of musical identity' and 'interpreters of the musical texts of life'.

We show that the room-temperature tetragonal phase is stabilized at low temperatures for pressures above 0.06 GPa, and its weight fraction attains a maximum in the region where superconductivity is observed under applied uniaxial pressure. Simultaneous resistivity measurements strongly suggest that this phase is responsible for the superconductivity in CaFe2As2 found below 10 K in samples subjected to nonhydrostatic pressure conditions.

title: The Symbolism of Play Behavior in Child-Centered Play Therapy
Creators: name: Andrewjeski, Kaitlin
Publisher: name: University of Nevada, Las Vegas
Year: 2019

description: Child-Centered Play Therapy (CCPT) is an evidence-based approach for mental health treatment with children. CCPT is based on the belief that play is a child’s natural language and so the therapist is required to make inferences of themes through observations of free play; however, there is no standard process by which themes are identified. The purpose of the current study is to gain detailed descriptions of play behavior in order to describe how themes emerge and how they are displayed in child-centered treatment. The themes were then used to describe the progression through the typical stages of child-centered play therapy. We interviewed 10 participants using a protocol adapted from previous research. Participants included therapists who reported the use of child-centered therapy (MFTs, LCSWs, PsyDs, PhDs) and were screened by the researcher to have received sufficient training/education. Thematic analysis was used to identify patterns among the transcripts and a list of themes was developed. A total of six themes emerged from the interviews that provide meaning to patterns of toy selections. A grounded theory approach was used to analyze the open codes and three general stages were produced. These stages display a progression through child-centered treatment, which show a child’s tendency to move from disorganized play, to consistent/repetitive play, and lastly to autonomous play with a clear point of conclusion.

Creators: name: Balogh, Mary Amanda

Year: 2019

description: The historic and current state of land in the Mojave Desert, including land managed by the National Park Service with fundamental goals of natural resource conservation and preservation, been severely degraded by a variety of anthropogenic disturbances. Due to increasingly sporadic and unpredictable precipitation patterns, land managers struggle to implement restoration projects with high success rates and are resource-limited for post-treatment monitoring. In this study, I examined success rates of biotic (outplanting, seeding) and abiotic (soil manipulation, vertical mulch) restoration treatments on various disturbance types in the creosote-bursage (Larrea tridentata-Ambrosia dumosa), blackbrush (Coleogyne ramosissima), and Joshua tree woodland (Yucca brevifolia) plant communities. Sites were surveyed in springs of 2018 and 2019 for annual and perennial plant species richness, percent cover, and perennial density to determine the effect size between unrestored, treatment, and reference (undisturbed) plot types. Sites were compared to determine what restoration treatment is most successful based on plant community, disturbance type, and the time since restoration or disturbance. Both biotic and abiotic treatments typically exhibited positive rather than negative restoration responses. Biotic treatments tended to have a more positive restoration success response than abiotic treatments. A large number of perennial effects were sensed while annual effects were often undetected. This study aims to provide evidence-based decision tools for land managers to choose restoration methods in an ecologically and economically effective manner.

description: We discuss the structure of 4D gauged supergravity algebras corresponding to globally non-geometric compactifications of F-theory, admitting a local geometric description in terms of 10D supergravity. By starting with the well known algebra of gauge generators associated to non-geometric type IIB fluxes, we derive a full algebra containing all, closed RR and NSNS, geometric and non-geometric dual fluxes. We achieve this generalization by a systematic application of SL(2,Z) duality transformations and by taking care of the spinorial structure of the fluxes. The resulting algebra encodes much information about the higher dimensional theory. In particular, tadpole equations and Bianchi identities are obtainable as Jacobi identities of the algebra. When a sector of magnetized (p,q) 7-branes is included, certain closed axions are gauged by the U(1) transformations on the branes. We indicate how the diagonal gauge generators of the branes can be incorporated into the full algebra, and show that Freed-Witten constraints and tadpole cancellation conditions for (p,q) 7-branes can be described as Jacobi identities satisfied by the algebra mixing bulk and brane gauge generators.

The geology and geochemistry of the Naringla Monzodiorite, and the mineralization and alteration of the associated Porphyry Copper Deposits, Yeoval, Central-Western N.S.W.
Creators: name: Cooke, DR
Publisher: name: University Of Tasmania
Year: 2023

description: A study of the petrology, geochemistry and field relationships of sedimentary, volcanic and plutonic rocks from the Yeoval district has revealed a complex and varied geological history. Volcanics derived from the nearby Molong Volcanic Rise were deposited with marine sediments in the Middle to Late Silurian. They were then deformed during the Bowning Orogeny. Intrusion of the Naringla Monzodiorite occurred in the Early Devonian. This is a heterogeneous body ranging in composition from pyroxenite cumulates to microgranodiorite and dacite porphyry. The latter two rock types are Co-genetic prior to pyroxene formed by the host to disseminated porphyry copper style mineralisation. basaltic andesites were erupted above the monzodiorite body final crystallization of the monzodiorite. The pyroxenites, bearing basaltic andesites and pyroxene crystal fractionation of augite from bearing monzodiorites a primitive magma of basaltic andesite composition. The chemical variations in the Naringla Monzodiorite (apart from the low-Si rocks) is thought to have been derived by chemical fractionation of hornblende, plagioclase and possibly biotite, although magma mixing and restite unmixing cannot be ruled out as formation processes. Hydrothermal alteration associated with the porpyritic intrusions has produced propylitic mineral assemblages in most of the rocks of the Naringla Monzodiorite. Alteration is most intense around the copper deposits, and occasional albitic alteration is developed. Alteration is of a weak and patch nature, and lateration zones are generally not developed. A small body of gabbro that outcrops adjacent to the Naringla Monzodiorite is probably unrelated due to chemical inconsistencies between the two units. The Ohley Adamellite intruded during the Middle Devonian, and contact metamorphosed the gabbro and a body of quartz-hornblende-diorite. The intrusion of rhyolite dykes into the Naringla Monzodiorite may have been related to the emplacement of the adamellite.The final geological event in the area was the emplacement of small basic dykes along east-west joints in the Naringla Monzodiorite. dykes are of probable Tertiary age.

description: We study the inflation process of universe based on the renormalizable quantum gravity formulated as a conformal field theory (CFT). We show that the power-law CFT spectrum approaches to that of the Harrison-Zel'dovich-Peebles type as the amplitude of gravitational potential gradually reduces during the inflation. The non-Gaussanity parameter is preserved within order of unity due to the diffeomorphism invariance. Sharp fall-off of the angular power spectrum of cosmic microwave background (CMB) at large scale is understood as a consequence of the existence of dynamical scale of the quantum gravity Λ_QG (\simeq 10^{17})GeV. The angular power spectra are computed and compared with the WMAP5 and ACBAR data with a quality of χ^2/dof \simeq 1.1.

description: The ratio $R_{τμ}(Υ(1S)) = Γ_{Υ(1S)\toτ^+τ^-}/Γ_{Υ(1S)\toμ^+μ^-}$ is measured using a sample of $(121.8\pm1.2)\times10^6$ $Υ(3S)$ events recorded by the BABAR detector. This measurement is intended as a test of lepton universality and as a search for a possible light pseudoscalar Higgs boson. In the standard model (SM) this ratio is expected to be close to 1. Any significant deviations would violate lepton universality and could be introduced by the coupling to a light pseudoscalar Higgs boson. The analysis studies the decays $Υ(3S)\toΥ(1S)π^+π^-$, $Υ(1S)\to l^+l^-$, where $l=μ,τ$. The result, $R_{τμ}(Υ(1S)) = 1.005 \pm 0.013(stat.) \pm 0.022(syst.)$, shows no deviation from the expected SM value, while improving the precision with respect to previous measurements.

description: In quantum information theory, von Neumann entropy plays an important role. The entropies can be obtained analytically only for a few states. In continuous variable system, even evaluating entropy numerically is not an easy task since the dimension is infinite. We develop the perturbation theory systematically for calculating von Neumann entropy of non-degenerate systems as well as degenerate systems. The result turns out to be a practical way of the expansion calculation of von Neumann entropy.

description: A grand vision of realization of smart and compact multifunctional microfluidic devices for wearable health monitoring, environment sensing and point-of-care tests emerged with the fast development of flexible electronics. As a vital component towards this vision, magnetic functionality in flexible fluidics is still missing although demanded by the broad utility of magnetic nanoparticles in medicine and biology. Here, we demonstrate the first flexible microfluidic analytic device with integrated high-performance giant magnetoresistive (GMR) sensors. This device can be bent to a radius of 2 mm while still retaining its full performance. Various dimensions of magnetic emulsion droplets can be probed with high precision using a limit of detection of 0.5 pl, providing broad applicability in high-throughput droplet screening, flow cytometry and drug development. The flexible feature of this analytic device holds great promise in the realization of wearable, implantable multifunctional platforms for biomedical, pharmaceutical and chemical applications.

description: In this paper the Hamiltonian of quantum electrodynamics with spatial cutoffs is investigated. We define a scaled total Hamiltonian and consider its asymptotic behavior. In the main theorem, it is shown that the scaled total Hamiltonian converges to a self-adjoint operator in the strong resolvent sense, and effective potentials are derived.

description: We present a study of electroweak production of top and antitop quarks in the s-channel mode at the LHC, including next-to-leading order (NLO) quantum chromodynamics (QCD) corrections to the production and decay of the single (anti)top quark. The spin is preserved in production and decay by using the narrow width approximation for the (anti)top quark. We show the effect of different O(alpha_s) contributions on the inclusive cross section and various kinematic distributions at parton level after imposing relevant kinematic cuts to select s-channel single top quark events. We also discuss several possibilities for measuring the top quark polarization.

description: One important recent trend in deposition technology is the continuous expansion of available processes towards higher ion assistance with the subsequent beneficial effects to film properties. Nowadays, a multitude of processes, including laser ablation and deposition, vacuum arc deposition, ion assisted deposition, high power impulse magnetron sputtering and plasma immersion ion implantation, are available. However, there are obstacles to overcome in all technologies, including line-of-sight processes, particle contaminations and low growth rates, which lead to ongoing process refinements and development of new methods. Concerning the deposited thin films, control of energetic ion bombardment leads to improved adhesion, reduced substrate temperatures, control of intrinsic stress within the films as well as adjustment of surface texture, phase formation and nanotopography. This review illustrates recent trends for both areas; plasma process and solid state surface processes. © 2010 by the authors.

description: Numerical ab initio variational calculations of the transition probabilities and ac Stark shifts in two-photon transitions of antiprotonic helium atoms driven by two counter-propagating laser beams are presented. We found that sub-Doppler spectroscopy is in principle possible by exciting transitions of the type (n,L)->(n-2,L-2) between antiprotonic states of principal and angular momentum quantum numbers n~L-1~35, first by using highly monochromatic, nanosecond laser beams of intensities 10^4-10^5 W/cm^2, and then by tuning the virtual intermediate state close (e.g., within 10-20 GHz) to the real state (n-1,L-1) to enhance the nonlinear transition probability. We expect that ac Stark shifts of a few MHz or more will become an important source of systematic error at fractional precisions of better than a few parts in 10^9. These shifts can in principle be minimized and even canceled by selecting an optimum combination of laser intensities and frequencies. We simulated the resonance profiles of some two-photon transitions in the regions n=30-40 of the \bar{p}^4He^+ and \bar{p} ^3He^+ isotopes to find the best conditions that would allow this.

Sustainable Highway Pavements The Evaluation of Pavement Quality Concrete Produced with Rice Husk Ash Binder
Creators: name: Hyndman, Fraser
Publisher: name: Leeds Beckett University

description: This thesis investigates the use of rice husk ash (RHA) as a sustainable alternative to traditional portland cement in rigid highway pavements. The literature review highlights the significant environmental impact of cement production, the historical development and properties of concrete, and the potential benefits of using RHA, a by-product of rice milling, due to its high pozzolanic activity and availability.The methodology involved preparing various concrete mixes, including control mixes and those with RHA replacements. Detailed tests were conducted to evaluate workability, compressive strength, tensile strength, curing time, and durability. The research adhered to the specifications set out in the Manual of Contract Documents for Highway Works (MCHW) and relevant British Standards. The preparation of materials included ensuring the quality and consistency of aggregates, cement, water, admixtures, and RHA. The concrete samples were tested for workability using slump tests, and mechanical properties were assessed through uniaxial compression and indirect tension tests.Key results indicate that RHA concrete mixes exhibit comparable or superior compressive strength to traditional mixes, with improved tensile strength and enhanced durability against environmental stressors such as freeze-thaw cycles and chloride penetration. The workability and curing times of RHA mixes were also found to be favourable, with RHA improving the mix's overall performance. The study also noted that RHA concrete had a lower heat evolution peak during curing, reducing the risk of thermal cracking.A field trial on the M180 motorway demonstrated the practical applicability of RHA concrete, showing satisfactory performance in real-world conditions. The concrete mix used in the field trial met the target strength requirements and exhibited good workability and durability. The findings suggest that RHA concrete not only meets structural and durability requirements but also significantly reduces the carbon footprint of pavement construction. This research concludes that RHA is a viable and sustainable alternative for use in pavement quality concrete. Recommendations for future work include long-term performance monitoring, economic feasibility studies, optimisation of mix designs, and the development of standards and guidelines to facilitate the adoption of RHA in the construction industry.
Q-sort study of family centered casework performance

description: The evaluation of social worker performance is a problem that frequently confronts the social work profession because the profession continually seeks to discover what it is doing for, and with, the clients it serves in order to learn how to serve them better. A number of studies of effect have been launched to this end. The Area Development Project of Vancouver, British Columbia, is one such study. The project seeks to test a specific treatment method, "integrated family services", on a selected group of one hundred multi-problem families. The experimental design calls for one hundred families in the treatment group and two hundred families in two control groups in order to test the hypothesis that the demonstrating services of the project are more effective in improving the functioning of families with complex problems than the "usual agency services" of health and welfare agencies. Studies of effect on casework services too often assume that there is no significant variation in the performances of professionally trained social workers when there is little reason to believe this to be the case. This study, which was carried out in conjunction with the Area Development Project, aimed at developing a Q-sort measure of family centered casework performance that could be used to test the hypothesis that there are significant differences between the inputs of professionally trained social workers. The proposed instrument would also document any differences between social worker performances should the hypothesis prove true. The completed Q-sort of Family Centered Casework Performance was applied to the Area Development Projects' treatment group social workers to generate a performance score for each of the workers as well as a profile description of the ideal family centered casework performance. It was possible to demonstrate that the inputs of the social workers differed greatly, while at the same time develop a precise profile description of the projects' "integrated family services". The study also attempted to relate the performance levels of the treatment group social workers to client movement in the cases that the workers carried. The establishment of a definite conclusion in regard to this relationship was not possible because of limitations in time and data, however, a means of analysis was developed for use with final data from the Area Development Project when it becomes available. The introductory chapter gives a brief summary of the problem of social worker evaluation, alternative ways of dealing with the problem and a statement of the scope and limitations of the study. The Theoretical framework of the study and the methods utilized are outlined in Chapter II. In Chapter III, the study findings are presented along with descriptive data on the study sample. The thesis concludes with a brief summary of the study and its' conclusions followed by some proposals for dealing with final data on client movement when they become available.
Electric dipole moments and disalignment of interstellar dust grains

description: The degree to which interstellar grains align with respect to the interstellar magnetic field depends on disaligning as well as aligning mechanisms. For decades, it was assumed that disalignment was due primarily to the random angular impulses a grain receives when colliding with gas-phase atoms. Recently, a new disalignment mechanism has been considered, which may be very potent for a grain that has a time-varying electric dipole moment and drifts across the magnetic field. We provide quantitative estimates of the disalignment times for silicate grains with size > approximately 0.1 micron. These appear to be shorter than the time-scale for alignment by radiative torques, unless the grains contain superparamagnetic inclusions.

description: A stable BiI 3 monosheet has been grown for the first time on the (0001) surface of the topological insulator Bi 2 Se 3 as confirmed by scanning tunnelling microscopy, surface X-ray diffraction, and X-ray photoemision spectroscopy. BiI 3 is deposited by molecular beam epitaxy from the crystalline BiTeI precursor that undergoes decomposition sublimation. The key fragment of the bulk BiI 3 structure, a∞2[I—Bi—I] layer of edge-sharing BiI 6 octahedra, is preserved in the ultra-thin film limit, but exhibits large atomic relaxations. The stacking sequence of the trilayers and alternations of the Bi—I distances in the monosheet are the same as in the bulk BiI 3 structure. Momentum resolved photoemission spectroscopy indicates a direct band gap of 1.2 eV. The Dirac surface state is completely destroyed and a new flat band appears in the band gap of the BiI 3 film that could be interpreted as an interface state.
