description: A variety of potential pathways for the synthesis of defined polymer networks were applied to (meth)acrylic acid based hydrogels and in-depth characterized. The anionic polymerization of a monomer and a bifunctional linker has been employed, as well as the utilization of efficient cross-linking procedures for the ligation of pre-formed telechelic polymers. The ligation techniques included the subsequent addition of a bifunctional monomer and the azide-alkyne Huisgen ligation. Reversible addition-fragmentation transfer polymerization was investigated as a complementary living polymerization procedure. The influence of the topology of the polymer networks on macroscopic properties were examined, such as the absorbency of sodium chloride solutions, the repulsion of salt during the swelling process and the mobility of ions within the network structure. In addition, 1H-NMR relaxometry, double quantum 1H-NMR and inverse size exclusion chromatography were employed to quantify the network architecture.
Radiation reaction and renormalization for a photon-like charged particle
Creators: name: Yaremko, Yurij
Publisher: name: arXiv

Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: A renormalization scheme which relies on energy-momentum and angular momentum balance equations is applied to the derivation of effective equation of motion for a massless point-like charge. Unlike the massive case, the rates of radiated energy-momentum and angular momentum tend to infinity whenever the source is accelerated. The external electromagnetic fields which do not change the velocity of the particle admit only its presence within the interaction area. The effective equation of motion is the equation on eigenvalues and eigenvectors of the electromagnetic tensor. The massless charges move along base line determined by the eigenvectors when the effective equation of motion possesses uniform solutions. It is interesting that the same solution arises in Rylov's model of magnetosphere of a rapidly rotating neutron star (pulsar).

D.2.1.3 Report with a strategy for communication activities
Creators: name: Caciagli, Laura
Publisher: name: Zenodo
Year: 2020

description: Scope of the GUTTA communication strategy is to facilitate the implementation of the project communication goals and make key stakeholders aware of the project's achievements. To this end, the communication strategy designs and provide a guidance to both project internal and project external communication activities. Scope of the internal communication is to facilitate an efficient and regular communication among GUTTA partners. Scope of the external communication is to create a network of project-external relationships and make key stakeholders aware of the project's outcomes. The current report will therefore illustrate the main target groups, the communication channels to be used, and the communication activities planned in the framework of the project.

description: Asymptotic Giant Branch variables are found to obey period-luminosity relations in the mid-IR similar to those seen at K_S (2.14 microns), even at 24 microns where emission from circumstellar dust is expected to be dominant. Their loci in the M, logP diagrams are essentially the same for the LMC and for NGC6522 in spite of different ages and metallicities. There is no systematic trend of slope with wavelength. The offsets of the apparent magnitude vs. logP relations imply a difference between the two fields of 3.8 in distance modulus. The colours of the variables confirm that a principal period with log P > 1.75 is a necessary condition for detectable mass-loss. At the longest observed wavelength, 24 microns, many semi-regular variables have dust shells comparable in luminosity to those around Miras. There is a clear bifurcation in LMC colour-magnitude diagrams involving 24 micron magnitudes.

description: The Plantagenet Beds generally are devoid of diagnostic fossils, but a bryozoal calcarenite from the Beds at Nanarup, near Albany, has yielded a well preserved fauna. A single sample of 25,000 specimens contains 166 categories (form, subspecies, species, genus etc.). All are described and figured. The following are defined as new: Haplophragmoides regularis, Textularia nanarupensis, T. colemani, T. simpsoni, T. jutsoni, Bolivinella tailori, Palmula hodgsoni, Saracenaria australiae, Vaginulina hornibrooki, Pseudopolymorphina carteri, Buliminella rutledgei, Angulogerina hunti, Epistominella macgowrani, Schackoinella wadeae, Australorotalia westraliensis n. gen., n. sp. (Rotaliidae), Operculina crespinae, Globigerina jenkinsi, G. ouachitaensis form basaapertura n. form, Eponides pustulosus, Linderina glaessneri and Hanzawaia westraliensis. Ten percent of the fauna is composed of planktonic species, of which Globanomalina micra, Globigerina ampliapertura form ampliapertura and Globigerapsis index are dominant, the latter making up 65% of the planktonic element. Statistical analysis of 1600 specimens of Globigerapsis index casts grave doubt on the biological validity of the planktonic foraminiferal genera Globigerinita, Tinophodella, Globigerinatheka and Inordinatosphaera. The sediments are correlated mainly within Australasia, but also throughout the Indo-Pacific region, Trinidad and southeast Asia. The planktonic fauna allows correlation with Carter's Faunal Unit 2, the Globorotalia cocoaensis Zone of Trinidad and the Globigerina gortanii turritilina Zone of Tanzania. The age of the fauna is Upper Eocene (Priabonian) . The composition of the fauna shows that it was deposited in water about 100' -120' deep under subtropical conditions. Reconstruction of the Upper Eocene palaeogeography suggests that the sediment accumu- lated in the lee of a series of islands of Precambrian rock.

description: Proving the unconditional security of a quantum key distribution (QKD) scheme is a highly challenging task as one needs to determine the most efficient attack compatible with experimental data. This task is even more demanding for continuous-variable QKD as the Hilbert space where the protocol is described is infinite dimensional. A very natural way to address this problem is to make an extensive use of the symmetries of the protocols. In this article, we investigate a symmetry in phase space that is particularly relevant to continuous-variable QKD, and explore the way towards a new quantum de Finetti theorem that would exploit this symmetry and provide a powerful tool to assess the security of continuous-variable protocols.

description: Symmetry-protected topological phases (SPTs) characterized by short-range entanglement include many states essential to understanding of topological condensed matter physics, and the extension to gapless SPTs provides essential understanding of their consequences. In this work, we identify a fundamental connection between gapless SPTs and recently-introduced multiplicative topological phases, demonstrating that multiplicative topological phases are an intuitive and general approach to realizing concrete models for gapless SPTs. In particular, they are naturally well-suited to realizing higher-dimensional, stable, and intrinsic gapless SPTs through combination of canonical topological insulator and semimetal models with critical gapless models in symmetry-protected tensor product constructions, opening avenues to far broader and deeper investigation of topology via short-range entanglement.
Hard Probes are the "Meridian Line", sQGP is the Forbidden City

Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: Relativistic heavy-ion collisions at BNL/RHIC have created a hot and dense nuclear matter, the strongly interacting Quark-Gluon Plasma (sQGP). Hard probes, high transverse momentum particles and jets, interact with the sQGP medium and lose energy. The interactions modify the properties of the hard probes; the medium responds to the energy loss of those probes in a collective way. Many properties of the sQGP have been learned from the modifications to the probes and the medium responses. I will review jet-like correlation results from RHIC, especially those measured by three-particle correlations, and discuss some of the fascinating physics.

description: We report on X-ray and soft gamma-ray observations of the black-hole candidate GX 339-4 during its 2007 outburst, performed with the RXTE and INTEGRAL satellites. The hardness-intensity diagram of all RXTE/PCA data combined shows a q-shaped track similar to that observed in previous outbursts.The evolution in the diagram suggested that a transition from hard-intermediate state to soft-intermediate state occurred, simultaneously with INTEGRAL observations performed in March. The transition is confirmed by the timing analysis presented in this work, which reveals that a weak type-A quasi-periodic oscillation (QPO) replaces a strong type-C QPO. At the same time, spectral analysis shows that the flux of the high-energy component shows a significant decrease in its flux. However, we observe a delay (roughly one day) between variations of the spectral parameters of the high-energy component and changes in the flux and timing properties. The changes in the high-energy component can be explained either in terms the high-energy cut-off or in terms of a variations in the reflection component. We compare our results with those from a similar transition during the 2004 outburst of GX 339-4.

Developing an understanding of algebraic symbols
Creators: name: Quinlan, Cyril Ronald Edmund
Publisher: name: University Of Tasmania
Year: 2023

description: The major objective of this research project was to investigate the difficulties that beginning algebra students experience in developing an understanding of the meaning and use of algebraic symbols. Learning problems identified by relevant research projects during the previous two decades provided a starting point, and items used in these projects for written tests or interviews were valuable in the formation of a new test instrument. By incorporating aspects investigated by several other researchers, a broad-based approach was employed to extend their work of applying psychological understandings of cognition to the learning processes involved in early algebra. Investigations examined interrelationships between measures previously studied in separate projects. Data were collected for analysis from a sample of 208 Year 7 secondary school students as they began their study of algebra in the form of generalized arithmetic. Methods of data collection were repeated written tests, interviews and lesson observations. To locate the responses of the beginning Year 7 students in the learning continuum about algebraic symbols as numerical variables, research data were also collected from another 309 Years 7 to 12 students. Scales were established for measuring and reporting on the patterns of thinking revealed by the students' responses. The pool of research information about the learning of algebra was expanded by the frequency data for individual items and for scaled groups of items. Comparisons and contrasts with findings of earlier researchers were reported where possible. Hierarchies of difficulty, as proposed by previous researchers for distinguishing levels of understanding of algebraic symbols, were tested for their applicability to the student sample and to see if they reflected any identifiable learning sequences. The most difficult challenge for students beginning their study of the algebra of generalized arithmetic was found to be the attainment of an understanding of algebraic symbols as representing numerical variables. Some Year 7 students made little progress towards this goal during the seven months of the study. The tendency to regard symbols as standing for objects or people was one focus of attention. Evidence supported the view that the level of achievement on the algebraic tasks presented is related to the degree of progress towards understanding algebraic symbols as numerical variables. Empirical data were shown to agree with psychological reasons for arranging some of the tasks into hierarchical orders of difficulty and/or into sequential orders of learning. There was some elucidation of the key steps in learning which distinguish students likely to progress in algebra.
title: Selenium Contamination: The Environmental Effectiveness of Current Treatment Methods in the Mining Industry Based on Water Quality Guidelines

Publisher: name: Vancouver Island University

description: 2023
description: Selenium (Se) contamination in water bodies and ecosystems presents challenges to the environment, including wild species, and human communities. The Elk Valley region in British Columbia (BC), Canada, exemplifies these challenges. This research examines the effectiveness of Teck's Saturated Rock Fill (SRF) technology in addressing selenium contamination in Elk Valley utilizing a desktop case study approach, literature review, data analysis, and site overview. The findings indicate that Teck's compliance position, with BC's water quality limits for selenium, is inadequate. However, monitoring data suggests that, despite non-compliance, contamination and environmental risks have not significantly increased. Teck's compliance was found to align with protective guidelines from WHO, Health Canada, and New Zealand, indicating sufficient protection for human and aquatic health. The study suggests that BC's more conservative standards may be unattainable, while guidelines from less-stringent jurisdictions are equally protective. Further analyses are recommended, to review the efficacy of BC's selenium management and treatment guidelines accordingly.

Solar observations

description: Metadata descriptions of Solar observations have so far only been standardized for space-based observations, but the standards have been mostly within a single space mission at a time, at times with significant differences between different mission standards. In the context of ground-based Solar observations, data has typically not been made freely available to the general research community, resulting in an even greater lack of standards for metadata descriptions. This situation makes it difficult to construct multi-instrument archives/virtual observatories with anything more than the most basic metadata available for searching, as well as making it difficult to write generic software for instrument-agnostic data analysis. This document describes the metadata recommendations developed under the SOLARNET EU project, which aims to foster more collaboration and data sharing between both ground-based and space-based solar observatories. The recommendations will be followed by data pipelines developed under the SOLARNET project as well as e.g. the Solar Orbiter SPICE pipeline, the SST CHROMIS/CRISP common pipeline, and the Alma pipeline for Solar data. These recommendations are meant to function as a common reference to which even existing diverse data sets may be related, for ingestion into solar virtual observatories and for analysis by generic software.
A critical layer model for turbulent pipe flow

Publisher: name: arXiv
Year: 2010
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: A model-based description of the scaling and radial location of turbulent fluctuations in turbulent pipe flow is presented and used to illuminate the scaling behaviour of the very large scale motions. The model is derived by treating the nonlinearity in the perturbation equation (involving the Reynolds stress) as an unknown forcing, yielding a linear relationship between the velocity field response and this nonlinearity. We do not assume small perturbations. We examine propagating modes, permitting comparison of our results to experimental data, and identify the steady component of the velocity field that varies only in the wall-normal direction as the turbulent mean profile. The "optimal" forcing shape, that gives the largest velocity response, is assumed to lead to modes that will be dominant and hence observed in turbulent pipe flow. An investigation of the most amplified velocity response at a given wavenumber-frequency combination reveals critical layer-like behaviour reminiscent of the neutrally stable solutions of the Orr-Sommerfeld equation in linearly unstable flow. Two distinct regions in the flow where the influence of viscosity becomes important can be identified, namely a wall layer that scales with $R^{+1/2}$ and a critical layer, where the propagation velocity is equal to the local mean velocity, that scales with $R^{+2/3}$ in pipe flow. This framework appears to be consistent with several scaling results in wall turbulence and reveals a mechanism by which the effects of viscosity can extend well beyond the immediate vicinity of the wall.

description: Each point of a simplex is expressed as a unique convex combination of the vertices. The coefficients in the combination are the barycentric coordinates of the point. For each point in a general convex polytope, there may be multiple representations, so its barycentric coordinates are not necessarily unique. There are various schemes to fix particular barycentric coordinates: Gibbs, Wachspress, cartographic, etc. In this paper, a method for producing sparse barycentric coordinates in polytopes will be discussed. It uses a purely algebraic treatment of affine spaces and convex sets, with barycentric algebras. The method is based on a certain decomposition of each finite-dimensional convex polytope into a union of simplices of the same dimension.
The organisation of electricity supply in Tasmania
Creators: name: Read, Peter Charles
Publisher: name: University Of Tasmania
Year: 2023

description: In Australia there is only one electricity supply authority that carries out all eight facets of public electricity supply throughout a whole state. Tasmania's Hydro- Electric Commission (H.E.C.) investigates, designs, arranges finance, constructs, generates, transmits, distributes and regulates. To the public the H.E.C. must look like a monolithic technological bureaucracy; purposeful, effective and reaching out into every corner of the state. To anyone under 30 this has always seemed the case. However, it is merely the present form of an industry that has changed and continues to change. There have been five phases in the organisation of electricity supply in Tasmania. The H.E.C. and its predecessor the Hydro-Electric Department (H.E.D.) have been involved in four of them and have modified their policies and organisation to fit the needs of the times. This dissertation traces the evolution of one of Australia's better known quangos, (1) documents its unplanned emergence from a failed commercial venture and the fundamental events that shaped the organisation of electricity supply in Tasmania and eventually produced the H.E.C. The overriding conclusion is that technology has shaped the organisation. Not just the technology of electricity supply, but the supporting technologies, particularly communications and electro-metallurgy. There are, however, other influences; personal, economic, social and political, that have shaped various phases of the organisation's evolution and remain in its present structure.

Subjects: School of leadership studies

description: 2024
description: This inquiry sought to promote positive change in work life for health care aides (HCAs) in long-term care. Participatory action research (Reason & Bradbury, 2008) methodology was used to engage 10 HCA participants in a virtual focus group. The study explored the primary research question: How can we improve health care aides’ work life from their perspective? Thematic analysis revealed five themes: (a) complex resident care, (b) personal safety, (c) communication with leadership, (d) staffing concerns, and (e) training needs. The conclusions are that an ideal work life is characterized by enhanced supports for providing complex resident care, personal safety at work, improved communication with leadership, adequate staffing, and training tailored to HCA needs. Recommendations include: implementing initiatives to enhance HCAs’ work life, such as strengthening supports for delivering complex resident care, prioritizing employee safety, enhancing communication channels and establishing a feedback mechanism, improving staffing allocation, customizing training, and supporting employee well-being. Keywords: health care aides, long-term care, participatory action research (PAR), quality of work life, work environment, work life conditions, care environment, personal support workers, resident care aides, leadership, medically complex patients

description: We present a new implementation of the infrared flux method (IRFM) using the 2MASS catalogue. We compute the theoretical quantities in the 2MASS JHKs filters by integrating theoretical fluxes computed from ATLAS models, and compare them directly with the observed 2MASS JHKs magnitudes. This is the main difference between our implementation of the IRFM and that of Ramirez & Melendez, since to introduce new stars at the lowest metallicities they transform the 2MASS JHKs magnitudes into the TCS photometric system. We merge in our sample the dwarfs stars from Alonso and collaborators with the stars in the sample of Ramirez & Melendez, Casagrande et al., Christlieb et al. and Bonifacio et al. The final number of stars in our sample is 555 dwarf and subgiant field stars, and 264 giant field stars. We derive a new bolometric flux calibration using the available Johnson-Cousins UBVRI and the 2MASS JHKs photometry. We also compute new Teff versus colour empirical calibrations using our extended sample of stars. We derive effectives temperatures for almost all the stars in the Alonso et al. sample and find that our scales of temperature are hotter by ~64K(dT=104K,N=332 dwarfs) and ~54K(dT=131K,N=202 giants).

description: 2024
description: Forty-seven samples collected from 23 creeks in Metro Vancouver, BC, Canada were analyzed to assess how different land use activities affect physicochemical properties in surface water and metal concentrations in sediments. The pH, total dissolved solids and electrical conductivity in surface water samples ranged from 5.50 to 8.27, 14.0 to 410.0 ppm, and 19.0 to 903.0 µS/cm, respectively, with no discernible relationship between the surrounding land use and the parameters. However, land use influenced metal concentrations in the sediments with arsenic, cadmium, chromium, copper, lead, silver, and zinc at some locations exceeding the Canadian Council of Ministers of the Environment sediment quality guidelines. Creeks closer to highways with heavy vehicular activities reported significantly higher concentrations of metals. Principal component and cluster analyses revealed anthropogenic and natural processes enrich the sediments with metals. It is therefore important to put measures in place to curb increase in metal concentrations in creek sediments.

description: Over the last decades, volumes of global agricultural production have increased significantly, thanks to specialization of farming systems and breeding of high yielding varieties. We have an increase in world population, which currently stands at around 7 billion, and is expected to rise to 9 billion, by the year 2050. That increasing population and its need for food, combined with the need for renewable sources of energy, has placed a great deal of pressure on arable land, and has meant, that there is scarcity of such land. At the same time, we have the phenomenon of climate change, producing a number of different impacts on productivity in agriculture. So, in consequence the need for innovation, mainly through new plant varieties is more relevant, than ever. Research is the future of agriculture, be it in terms of productivity, food quality and protection of the environment.

Creators: name: Harvey, David
Publisher: name: Unknown
Year: 2013
Subjects: Agricultural and Food Policy

description: The brief for this paper (contained in the title) is, of course, far too wide for one Â½ hour session. However, it may be useful to try to summarise the critical messages of agricultural (applied) economics to the â€˜realâ€™ world of agribusiness and management. In so doing, I hope to be able to highlight the critical shortcomings of the discipline of economics as well. The problem? At the considerable risk of over-simplification (the congenital condition of applied economists), the world is divided into two unequal parts â€“ those who believe in and fully subscribe to the proposition that â€˜economics rules, OKâ€™; those who consider that economics is either marginal to the human condition and sustainability, or should be made so very quickly. On the one hand, markets and commercial viability (and associated competition, level playing fields, minimal regulation and free trade) can be considered as the bedrock of economic sustainability, without which all talk of environmental or social sustainability is mere romantic rhetoric, with no clear guidance for current or future behavior short of praying for the second coming. The devil is in the detail. On the other hand, pursuit of profit at the expense of all other considerations is seen as being at the heart of our current problems â€“ notably the issues of environmental degradation, climate change, financial market instability and consequent real economic instability. These issues are clearly seen as potentially leading to the demise of democracy, the emergence of anarchy and the ultimate degradation of the human condition. The devil is in the conception. How can we make sense of these apparently inherently contradictory conceptions?

In support of the introduction of the idea of biologization, its tools such as probiotechnology are presented and the authors refer to the need of changing the current dominant paradigm of treating only the symptoms and accepting the paradigm of tackling the underlying causes. It gives examples of probiotechnology applications in the revitalization of agroecosystems and its beneficial effects on the fertile power of the soil.

B {\bf 40}, 546 (1989)] at the leading order, and to the bosonic Dynamical Mean Field Theory as a first correction, as recently derived by Byczuk and Vollhardt [Phys. Rev. B {\bf 77}, 235106 (2008)]. We obtain an alternative form of the equation using the occupation number representation, which can be easily solved with an arbitrary numerical precision, for any finite connectivity. We thus compute the transition line between the superfluid and Mott insulator phases of the model, along with thermodynamic observables and the space and imaginary time dependence of correlation functions. The finite connectivity of the Bethe lattice induces a richer physical content with respect to its infinitely connected counterpart: a notion of distance between sites of the lattice is preserved, and the bosons are still weakly mobile in the Mott insulator phase. The Bethe lattice construction can be viewed as an approximation to the finite dimensional version of the model. We show indeed a quantitatively reasonable agreement between our predictions and the results of Quantum Monte Carlo simulations in two and three dimensions.

PL4_Paper - Aflatoxin: Quality Institutions In The Groundnut Value Chain In Ghana
Creators: name: Florkowski, Wojciech J.

Publisher: name: Unknown
Year: 2013
Subjects: Crop Production/Industries

description: The paper examines opportunities for afaltoxin reduction in peanuts. Aflatoxin contamination of peanuts is common in Sub-Saharan Africa including Ghana. Because of its detrimental health effects and economic losses, reduction of aflatoxin contamination in peanuts and peanut products is highly desirable. The paper uses data collected from farmers in the primary peanut growing area, the Northern Region, to illustrate the disparities between the current practices and the desired practices known to reduce aflatoxin presence in peanuts. The outlined containment strategy involves combining the pre- and postharvest methods to aflatoxin reduction proposing the time sequence of implementing individual elements of the strategy.

The evolution of virulence in RNA viruses under a competition-colonization trade-off

description: RNA viruses exist in large intra-host populations which display great genotypic and phenotypic diversity. We analyze a model of viral competition between two different viral strains infecting a constantly replenished cell pool, in which we assume a trade-off between the virus' colonization skills (cell killing ability or virulence) and its local competition skills (replication performance within coinfected cells). We characterize the conditions that allow for viral spread by means of the basic reproductive number and show that a local coexistence equilibrium exists, which is asymptotically stable. At this equilibrium, the less virulent competitor has a reproductive advantage over the more virulent colonizer. The equilibria at which one strain outcompetes the other one are unstable, i.e., a second viral strain is always able to permanently invade. One generalization of the model is to consider multiple viral strains, each one displaying a different virulence. However, to account for the large phenotypic diversity in viral populations, we consider a continuous spectrum of virulences and present a continuum limit of this multiple viral strains model that describes the time evolution of an initial continuous distribution of virulence. We provide a proof of the existence of solutions of the model's equations and present numerical approximations of solutions for different initial distributions. Our simulations suggest that initial continuous distributions of virulence evolve towards a stationary distribution that is extremely skewed in favor of competitors. Consequently, collective virulence attenuation takes place. This finding may contribute to understanding the phenomenon of virulence attenuation, which has been reported in previous experimental studies.

A C$^{18}$O study of the origin of the power-law nature in the IMF
Creators: name: Ikeda, Norio

description: We have performed C$^{18}$O ($J$=1--0) mapping observations of a $20'\times20'$ area of the OMC-1 region in the Orion A cloud. We identified 65 C$^{18}$O cores, which have mean radius, velocity width in FWHM, and LTE mass of 0.18$\pm$0.03 pc, 0.40$\pm$0.15 km s$^{-1}$, and 7.2$\pm$4.5 $M_\odot$, respectively. All the cores are most likely to be gravitationally bound by considering the uncertainty in the C$^{18}$O abundance. We derived a C$^{18}$O core mass function, which shows a power-law-like behavior above 5 $M_\odot$. The best-fit power-law index of $-2.3\pm0.3$ is consistent with those of the dense core mass functions and the stellar initial mass function (IMF) previously derived in the OMC-1 region. This agreement strongly suggests that the power-law form of the IMF has been already determined at the density of $\sim10^{3}$ cm$^{-3}$, traced by the C$^{18}$O ($J$=1--0) line.

Resonant leptogenesis and tribimaximal leptonic mixing with A4 symmetry

description: We investigate the viability of thermal leptogenesis in type-I seesaw models with leptonic flavour symmetries that lead to tribimaximal neutrino mixing. We consider an effective theory with an A4 x Z3 x Z4 symmetry, which is spontaneously broken at a scale much higher than the electroweak scale. At the high scale, leptonic Yukawa interactions lead to exact tribimaximal mixing and the heavy Majorana neutrino mass spectrum is exactly degenerate. In this framework, leptogenesis becomes viable once this degeneracy is lifted either by renormalization group effects or by a soft breaking of the A4 symmetry. The implications for low-energy neutrino physics are discussed.

description: We study the Bisognano-Wichmann Hamiltonian for fractional quantum Hall states defined on a sphere and explore its relationship with the entanglement Hamiltonian associated to the state. We present results for several examples, namely the bosonic Laughlin state stabilized by contact two-body interactions and the bosonic Moore-Read state stabilized by either three- or two-body interactions. Our findings demonstrate that the Bisognano-Wichmann Hamiltonian provides a reliable approximation of the entanglement Hamiltonian as a fully-local operator that can be written without any prior knowledge of the specific state under consideration.

description: Three new Zn(II) complexes, [Zn2L2(OAc)2]2CH3OH (1), [ZnL(3-NA)2]·H2O (2) and [ZnL(2-NA)2] (3) were synthesized by the reaction of Zn(CH3COO)2·2H2O or Zn(ClO4)2·6H2O with 2-amino-N'-(pyridin-2-ylmethylene)benzohydrazide (HL), 3-nitrobenzoic acid (3-NA) or 2-nitrobenzoic acid (2-NA). The complexes were characterized by elemental analyses, single crystal X-ray diffraction, IR, UV-Vis and 1H NMR spectroscopy. The single crystal X-ray diffraction analyses revealed that the Zn ions in the complexes are five-coordinate in tetragonal pyramid configuration. The complexes and their starting materials Zn(CH3COO)2·2H2O and Zn(ClO4)2·6H2O were studied for their catalytic performance in the selective oxidation of cyclohexane (Cy) with aqueous H2O2 as oxidant. The conditions such as time, the amount of H2O2, solvent and HNO3 additive were optimized. The results showed that 3 has the best activity under mild conditions compared to the starting zinc materials and the referenced zinc complexes.
A Model of Universe Anisotropization

description: The presence of a nonconformally invariant term in the photon sector of the Lorentz-violating extension of Standard Model of particle physics, the "Kostelecký term" $\mathcal{L}_K \propto (k_F)_{αβμν} F^{αβ} F^{\m ν}$, enables a superadiabatic amplification of magnetic vacuum fluctuations during de Sitter inflation. For a particular form of the external tensor $k_F$ that parameterizing Lorentz violation, the generated field possesses a planar symmetry at large cosmological scales and can have today an intensity of order of nanogauss for a wide range of values of parameters defining inflation. This peculiar magnetic field could account for the presently-observed galactic magnetic fields and induces a small anisotropization of the universe at cosmological scales. The resulting Bianchi I model could explain the presumedly low-quadrupole power in the Cosmic Microwave Background radiation.
