description: This paper complements a new lattice formulation of SU(2) Yang-Mills theory written in terms of new variables in a compact form proposed in the previous paper. The new variables used in the formulation were once called the Cho--Faddeev--Niemi or Cho--Faddeev--Niemi--Shabanov decomposition. Our formulation enables us to explain the infrared ``Abelian'' dominance, in addition to magnetic monopole dominance shown in the previous paper, in the gauge invariant way without relying on the specific gauge fixing called the maximal Abelian gauge used in the conventional investigations. In this paper, especially, we demonstrate by numerical simulations that gluon degrees of freedom other than the ``Abelian'' part acquire the mass to be decoupled in the low-energy region leading to the infrared Abelian dominance.

description: Detecting the presence of circumstellar dust around nearby solar-type main sequence stars is an important pre-requisite for the design of future life-finding space missions such as ESA's Darwin or NASA's Terrestrial Planet Finder (TPF). The high Antarctic plateau may provide appropriate conditions to perform such a survey from the ground. We investigate the performance of a nulling interferometer optimised for the detection of exozodiacal discs at Dome C, on the high Antarctic plateau, and compare it to the expected performance of similar instruments at temperate sites. Based on the currently available measurements of the turbulence characteristics at Dome C, we adapt the GENIEsim software (Absil et al. 2006, A&A 448) to simulate the performance of a nulling interferometer on the high Antarctic plateau. To feed a realistic instrumental configuration into the simulator, we propose a conceptual design for ALADDIN, the Antarctic L-band Astrophysics Discovery Demonstrator for Interferometric Nulling. We assume that this instrument can be placed above the 30-m high boundary layer, where most of the atmospheric turbulence originates. We show that an optimised nulling interferometer operating on a pair of 1-m class telescopes located 30 m above the ground could achieve a better sensitivity than a similar instrument working with two 8-m class telescopes at a temperate site such as Cerro Paranal. The detection of circumstellar discs about 20 times as dense as our local zodiacal cloud seems within reach for typical Darwin/TPF targets in a integration time of a few hours. Moreover, the exceptional turbulence conditions significantly relax the requirements on real-time control loops, which has favourable consequences on the feasibility of the nulling instrument.

description: Considering the dipole-dipole coupling intensity between two atoms and the field in the Fock state, the entanglement dynamics between two atoms that are initially entangled in the system of two two-level atoms coupled to a single mode cavity in the presence of phase decoherence has been investigated. The two-atom entanglement appears with periodicity without considering phase decoherence, however, the phase decoherence causes the decay of entanglement between two atoms, with the increasing of the phase decoherence coefficient, the entanglement will quickly become a constant value, which is affected by the two-atom initial state, Meanwhile the two-atom quantum state will forever stay in the maximal entangled state when the initial state is proper even in the presence of phase decoherence. On the other hand, the Bell violation and the entanglement does not satisfy the monotonous relation, a large Bell violation implies the presence of a large amount of entanglement under certain conditions, while a large Bell violation corresponding to a little amount of entanglement in certain situations. However, the violation of Bell-CHSH inequality can reach the maximal value if two atoms are in the maximal entangled state, or vice versa.

description: Enhanced diffusion of gold atoms into silicon substrate has been studied in Au thin films of various thicknesses (2.0, 5.3, 10.9 and 27.5 nm) deposited on Si(111) and followed by irradiation with 1.5 MeV Au2+ at a flux of 6.3x10^12 ions cm-2 s-1 and fluence up to 1x10^15 ions cm-2. The high resolution transmission electron microscopy measurements showed the presence of gold silicide formation for the above-mentioned systems at fluence greater than equal to 1x1014 ions cm-2. The maximum depth to which the gold atoms have been diffused at a fluence of 1x10^14 ions cm-2 for the cases of 2.0, 5.3, 10.9 and 27.5 nm thick films has been found to be 60, 95, 160 and 13 nm respectively. Interestingly, at higher fluence of 1x1015 ions cm-2 in case of 27.5 nm thick film, gold atoms from the film transported to a maximum depth of 265 nm in the substrate. The substrate silicon is found to be amorphous at the above fluence values where unusually large mass transport occurred. Enhanced diffusion has been explained on the basis of ion beam induced, flux dependent amorphous nature of the substrate, and transient beam induced temperature effects. This work confirms the absence of confinement effects that arise from spatially confined structures and existence of thermal and chemical reactions during ion irradiation.

description: Ultralight bosons can be abundantly produced through superradiance process by a spinning black hole and form a bound state with hydrogen-like spectrum. We show that such a "gravitational atom" typically possesses anomalously large mass quadrupole and leads to significant orbital precession when it forms an eccentric binary with a second compact object. Dynamically formed black hole binaries or pulsar-black hole binaries are typically eccentric during their early inspirals. We show that the large orbital precession can generate distinct and observable signature in their gravitational wave or pulsar timing signals.

description: In this talk, we investigate the implications of R-parity violating (RPV) operators in a model with family symmetry. Family symmetry can determine the form of RPV operators as well as the Yukawa matrices. We consider a concrete model with non-abelian discrete symmetry Q_6, which has only three RPV trilinear operators with no baryon number violating terms. We find that ratios of decay rates of the lepton flavor violating processes are fixed thanks to the family symmetry, predicting BR(tau to 3e)/BR(tau to 3mu) ~ 4 m_{mu}^2/m_{tau}^2.

description: We assess transport properties of heavy quarks in the Quark-Gluon Plasma (QGP) using static heavy-quark (HQ) potentials from lattice-QCD calculations in a Brueckner many-body T-matrix approach to evaluate elastic heavy-quark-light-quark scattering amplitudes. In the attractive meson and diquark channels resonance states are formed for temperatures up to ~1.5 T_c, increasing pertinent drag and diffusion coefficients for heavy-quark rescattering in the QGP beyond the expectations from perturbative-QCD calculations. We use these transport coefficients, complemented with perturbative elastic HQ gluon scattering, in a relativistic Langevin simulation to obtain HQ p_t distributions and elliptic flow (v_2) under conditions relevant for the hot and dense medium created in ultrarelativistic heavy-ion collisions. The heavy quarks are hadronized to open-charm and -bottom mesons within a combined quark-coalescence fragmentation scheme. The resulting single-electron spectra from their semileptonic decays are confronted with recent data on "non-photonic electrons" in 100 AGeV Au-Au collisions at the Relativistic Heavy-Ion Collider (RHIC).

Neutrino symmetries from high to low scales

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Proposed symmetry relations, e.g., quark-lepton complementarity (QLC) or tribimaximal mixing (TBM), need to be imposed at a high scale $\wedge \sim 10^{12}$ GeV characterising the large masses of right-handed neutrinos required to implement the seesaw mechanism. RG evolution down to the laboratory scale $λ\sim 10^3$ GeV, generically prone to spoil these relations and their predicted neutrino mixing patterns, can be made to preserve them by appropriately constraining the Majorana phases $α_{2,3}$. This is explicitly demonstrated in the MSSM for two versions of QLC and two versions of TBM. A preference for $α_2 \simeq π$ (i.e. $m_1 \simeq - m_2$) emerges in each case. Discrimination among the four cases is shown to be possible by future measurements of $θ_{13}$.

description: Versatile features of impurity doping effects on perovskite manganites, $R_{0.6}$Sr$_{0.4}$MnO$_{3}$, have been investigated with varying the doing species as well as the $R$-dependent one-electron bandwidth. In ferromagnetic-metallic manganites ($R$=La, Nd, and Sm), a few percent of Fe substitution dramatically decreases the ferromagnetic transition temperature, leading to a spin glass insulating state with short-range charge-orbital correlation. For each $R$ species, the phase diagram as a function of Fe concentration is closely similar to that for $R_{0.6}$Sr$_{0.4}$MnO$_{3}$ obtained by decreasing the ionic radius of $R$ site, indicating that Fe doping in the phase-competing region weakens the ferromagnetic double-exchange interaction, relatively to the charge-orbital ordering instability. We have also found a contrastive impact of Cr (or Ru) doping on a spin-glass insulating manganite ($R$=Gd). There, the impurity-induced ferromagnetic magnetization is observed at low temperatures as a consequence of the collapse of the inherent short-range charge-orbital ordering, while Fe doping plays only a minor role. The observed opposite nature of impurity doping may be attributed to the difference in magnitude of the antiferromagnetic interaction between the doped ions.

description: The electron capture in $^{163}\mathrm{Ho}$ experiment (ECHo) is designed to directly measure the effective electron neutrino mass by analysing the endpoint region of the $^{163}\mathrm{Ho}$ electron capture spectrum. We present a data reduction scheme for the analysis of high statistics data acquired with the first phase of the ECHo experiment, ECHo-1k, to reliably infer the energy of $^{163}\mathrm{Ho}$ events and discard triggered noise or pile-up events. On a first level, the raw data is filtered purely based on the trigger time information of the acquired signals. On a second level, the time profile of each triggered event is analysed to identify the signals corresponding to a single energy deposition in the detector. We demonstrate that events not belonging to this category are discarded with an efficiency above 99.8%, with a minimal loss of $^{163}\mathrm{Ho}$ events of about 0.7%. While the filter using the trigger time information is completely energy independent, a slight energy dependence of the filter based on the time profile is precisely characterised. This data reduction protocol will be important to minimise systematic errors in the analysis of the $^{163}\mathrm{Ho}$ spectrum for the determination of the effective electron neutrino mass.

Doping concentrations up to ~10^13 cm-2 are estimated from the G peak shift and width, and the variation of both position and relative intensity of the second order 2D peak. Asymmetric G peaks indicate charge inhomogeneity on the scale of less than 1 micron.

Publisher: name: arXiv

description: We show that stable double-frequency orbits form the backbone of double bars, because they trap around themselves regular orbits, as stable closed periodic orbits do in single bars, and in both cases the trapped orbits occupy similar volume of phase-space. We perform a global search for such stable double-frequency orbits in a model of double bars by constructing maps of trajectories with initial conditions well sampled over the available phase-space. We use the width of a ring sufficient to enclose a given map as the indicator of how tightly the trajectory is trapped around a double-frequency orbit. We construct histograms of these ring widths in order to determine the fraction of phase-space occupied by ordered motions. We build 22 further models of double bars, and we construct histograms showing the fraction of the phase-space occupied by regular orbits in each model. Our models indicate that resonant coupling between the bars may not be the dominant factor reducing chaos in the system.

description: Two types of average structures of a single knotted ring polymer are studied by Brownian dynamics simulations. For a ring polymer with N segments, its structure is represented by a 3N -dimensional conformation vector consisting of the Cartesian coordinates of the segment positions relative to the center of mass of the ring polymer. The average structure is given by the average conformation vector, which is self-consistently defined as the average of the conformation vectors obtained from a simulation each of which is rotated to minimize its distance from the average conformation vector. From each conformation vector sampled in a simulation, 2N conformation vectors are generated by changing the numbering of the segments. Among the 2N conformation vectors, the one closest to the average conformation vector is used for one type of the average structure. The other type of the averages structure uses all the conformation vectors generated from those sampled in a simulation. In thecase of the former average structure, the knotted part of the average structure is delocalized for small N and becomes localized as N is increased. In the case of the latter average structure, the average structure changes from a double loop structure for small N to a single loop structure for large N, which indicates the localization-delocalization transition of the knotted part.

description: Generational differences in societies are characteristics generally attributed to people's age that constitute a sociocultural phenomenon. Divisions in the generations differ across nations and extend even to civilizations. Perception and recognition of the different characteristics of each generation affect the cooperation between people in social, political, and economic capacities, and subsequently extend to entities in the public, informal, commercial, and nongovernmental sectors. From the perspective of social justice, it is important to draw attention to how workplace management techniques are used to promote equal opportunities among representatives of various generations.

Distribution and ecology. Anthalona harti is distributed in the tropics and subtropics of the Eastern Hemisphere (South Europe, Africa and also Middle, Southwest, South and Southeast Asia). In Asia, this crustacean is represented by the subspecies A. harti harti (Van Damme et al. 2011; Sinev & Kotov 2012; Korovchinsky 2013; Korovchinsky et al. 2021b; Dadykin et al. 2024b). In the Oriental region, it is the most common member of the genus, which in many earlier sources was attributed to Alona verrucosa Sars, 1901, Biapertura verrucosa (Sars, 1901) or Biapertura pseudoverrucosa (Sars, 1901), the synonyms of modern Anthalona verrucosa (Sars, 1901), now recognized as an inhabitant only of the Neotropics (Fernando 1974; Idris & Fernando 1981; Idris 1983; Michael & Sharma 1988; Rane 2002, 2005, 2011; Maiphae et al. 2005, 2008; Van Damme et al. 2011; Sinev & Kotov 2012; Chatterjee et al. 2013; Korovchinsky 2013; Kotov et al. 2013b; Ji et al. 2015; Padhye & Dumont 2015; Sinev & Yusoff 2015, 2018; Sinev et al. 2015, 2020; Sinev 2016; Sharma & Sharma 2017; Gogoi et al. 2018; Tiang-nga et al. 2020; Choedchim & Maiphae 2023). From Vietnam, this chidorid is known as Biapertura pseudoverrucosa verrucosa (Sars, 1901) (Dang et al. 1980; Dang & Ho 2001) and by its present name (Korovchinsky 2013; Sinev & Korovchinsky 2013; Gusakov et al. 2014; Zhdanova 2014; Sinev & Semenyuk 2021).
Anthalona harti harti inhabits various permanent and temporary water bodies, usually rich in aquatic vegetation: lakes, reservoirs, ponds, paddy fields, pools, swamps, floodplains, etc. In large bodies of water, it is associated with the littoral zone. The species can be found at the bottom, in plankton, among thickets (Idris 1983; Van Damme et al. 2011; Sinev & Korovchinsky 2013; Zhdanova 2014; Padhye & Dumont 2015; Sinev & Yusoff 2015; Sinev et al. 2015; Sinev 2016; Korovchinsky et al. 2021b; Choedchim & Maiphae 2023). In our material, it was found only in natural lakes, in the open littoral and in the rhizosphere of floating plants (see Appendix 1).

description: Characterising the circumstellar dust around nearby main sequence stars is a necessary step in understanding the planetary formation process and is crucial for future life-finding space missions such as ESA's Darwin or NASA's Terrestrial Planet Finder (TPF). Besides paving the technological way to Darwin/TPF, the space-based infrared interferometers Pegase and FKSI (Fourier-Kelvin Stellar Interferometer) will be valuable scientific precursors in that respect. In this paper, we investigate the performance of Pegase and FKSI for exozodiacal disc detection and compare the results with ground-based nulling interferometers. Besides their main scientific goal (characterising hot giant extrasolar planets), Pegase and FKSI are very efficient in assessing within a few minutes the level of circumstellar dust in the habitable zone around nearby main sequence stars. They are capable of detecting exozodiacal discs respectively 5 and 1 time as dense as the solar zodiacal cloud and they outperform any ground-based instrument. Unlike Pegase, FKSI can achieve this sensitivity for most targets of the Darwin/TPF catalogue thanks to an appropriate combination of baseline length and observing wavelength. The sensitivity of Pegase could, however, be significantly boosted by considering a shorter interferometric baseline length. These space-based interferometers would be complementary to Antarctica-based instruments in terms of sky coverage and would be ideal instruments for preparing future life-finding space missions.

Strategic planning in a small community health care setting
Creators: name: Hatlevik, Norman M.
Publisher: name: University of British Columbia
Year: 2010

description: This study provides an overview of the strategic planning process and presents the hypothesis that strategic planning is not only applicable to a small, community health setting but essential. The paper discusses the present situation which hospitals, especially small community hospitals, find themselves in and attempts to determine if the strategic planning process can offer advocacy prescriptions and a format for survival. It is aimed a encouraging a practical interest in the theoretical strategic planning process. While this is not a "model-building" exercise, the issues discussed are of concern to both the theory builder and the practitioner. An attempt is made to go beyond the existing literature on strategic planning to a discussion of the intrinsic, indirect or "invisible" factors peculiar to the process and to hospitals, factors which are critical and require the attention of boards and administrators. While the study attempts to simplify the strategic planning process, the additional discussion and emphasis on these "indirect" factors may appear to make the attempted transition from theory to practice more foreboding a process than it is. This study is developed by way of a literature review and case study analysis. The Case Study describes how one small community hospital became concerned about their capabilities of dealing with the political and economic forces that would affect the future of their facility and how they developed a strategic planning approach designed to ensure the survival of their community organization. The dominant role for both the Board and Administration became one of strategic planners. Part One provides an overview of the health care system and the current issues that are confronting the system. Part Two briefly describes the hospital industry and discusses the complexity of hospitals. Part Three describes the characteristics of small community hospitals. Part Four discusses the "state of the art" of planning in the hospital industry. Part Five provides a definition of strategic planning and describes special considerations. The reader is taken through the strategic planning process in a step-by-step manner. It is in this section during discussion of the roles of the main players that the many "invisible" factors are illuminated. Part Seven presents the Case Study and attempts to apply theory to practice. Part Eight provides concluding comments on the application of the strategic planning process in a small, community hospital. The main hypothesis of this study is that theoretical strategic planning is indeed applicable and implementable in a small, community health care setting. It was proposed and found that theoretical strategic planning can and does allow an organization to predict and influence its future.

description: In this essay we show that quantum gravity and the spin-statistics theorem have very interesting consequences for dark matter candidates. Quantum gravity can lead to fifth force type interactions that lead to a lower bound on the masses of bosonic candidates. In the case of fermions, the spin-statistics theorem leads to a lower bound on fermion masses. For both bosonic and fermionic dark matter candidates, quantum gravity leads to a decay of dark matter particles. A comparison of their lifetime with the age of the universe leads to an upper bound on their masses. For singlet scalar dark matter fields, we find $10^{-3}{\rm eV} \lesssim m\lesssim 10^{7}{\rm eV}$.

description: A model for developing and maintaining institutional repositories through cooperation of the University of Belgrade Computer Center (UBCC) with (so far, seven) research organizations is presented. It has resulted in improved visibility of local scientific output and has created an interoperable environment for information exchange. The infrastructure is developed and maintained by the UBCC IT team, whereas each institution has its own repository manager responsible for content. The main focus in developing institutional repositories is compliance with Open Science principles, standardized metadata, licenses, reliance on the non-proprietary and open source platform (DSpace). The repositories are now harvested by aggregators and services (OpenAIRE, CORE, BASE, Unpaywall, Google Scholar). This model is flexible, providing to new partners tested and optimized structure. It is also expandable, i.e. new services may be added, e.g. the Altmetric.com widget or in-house developed tools for massive metadata editing and import. The model described could be interesting, especially for repository managers and users from developing countries. It is demonstrated that proper coordination and standardized procedures could lead to an interoperable and sustainable network of repositories in an environment with no repository infrastructure, ensuring optimal information exchange with users, both human beings or machines.

Description
SHELL (Figs 34, 61). Medium-sized (3.15 - 3.40 mm high x 1.80 - 2.05 mm wide), of 4.5 - 5.0 whorls. Ovateacuminate, spire narrowly acuminate (spire angle 68 - 77°). Apex sharply pointed. Embryonic whorls smoothly granulate. Later whorls with few, widely-spaced, coarse ribs (5 - 7 per mm on penultimate whorl). Sutures very deep. Umbilicus narrowly open. Peristome complete, almost detached. Outer palatal surface of aperture with a depression corresponding to the lower palatal teeth. Dentition 6-fold, consisting of: one complex, V-shaped and flaring parietal tooth; three palatal teeth, the lower two larger and set low down on the palatal surface, not forming a parieto-palatal sinus; one basal, in-running denticle; and one shallow but strong, in-running columellar tooth. Shells and anatomy of juveniles unknown.
Range and habitat
Submontane forest (970 m elevation) in the East Usambara Mountains, northeastern Tanzania.
Remarks
The complex dentition and detached peristome of D. frontierarum sp. nov. are unlike that of any other Dadagulella gen. nov. species. It is also characteristic for its few whorls, few ribs and sharply pointed apex. Biogeographically a close relationship with other species in and around the East Usambaras would seem likely but there is no strong resemblance.

description: Microstructural features and mechanical properties of an Al-Mg-Si alloy processed by high-pressure torsion have been investigated using transmission electron microscopy, X-ray diffraction, three-dimensional atom probe, tensile tests and microhardness measurements. It is shown that HPT processing of the Al-Mg-Si alloy leads to a much stronger grain size refinement than of pure aluminium (down to 100 nm). Moreover, massive segregation of alloying elements along grain boundaries is observed. This nanostructure exhibits a yield stress even two times higher than that after a standard T6 heat treatment of the coarse grained alloy

description: We find an exact analytical solution of the reduced density matrix from the Feynman-Vernon influence functional theory for a wave packet influenced by an environment containing a few discrete modes. We obtain two intrinsic energy scales relating to the time scales of the system and the environment. Different relationship between these two scales alters the overall form of the solution of the system. We also introduce a decoherence measure for a single wave packet which is defined as the ratio of Schrödinger uncertainty over the delocalization extension of the wave packet and characterizes the time-evolution behavior of the off-diagonal reduced density matrix element. We utilize the exact solution and the docherence measure to study the wave packet decoherence dynamics. We further demonstrate how the dynamical diffusion of the wave packet leads to non-Markovian decoherence in such a microscopic environment.

description: The rise of the new economy has increased the importance of creative thought needed for developmental change (Bridgstock, 2013). The presence of creative individuals in a community brings about innovation, so creative city and nation planning has been implemented in some developed countries to promote positive development (Kakiuchi, 2014). This study draws on previous research within the topic of cultural entrepreneurism, the livelihoods of artists’, and tourism. This qualitative study was carried out in two sites in Australia: Melbourne, Victoria and Eumundi, Queensland. The purpose of this study was to determine if creativity and personal income was affected by the commercialization of local artists in Australian markets. The objectives of the study were to: identify factors that contributed to the economic sustainability of artists, inquire about the influence tourism had on the personal income of artists, and gauge their subjective well-being. Recruitment occurred at arts markets where artists were approached using a snowball sampling method. The data collection period lasted 6 weeks and the results indicated that 31% of respondents had achieved economic sustainability through their artwork, whereas 19% stated that the income generated from art-making was partly sufficient and was characterised by fluctuations, and finally 50% of respondents needed to supplement their income from art through other means. Primary sources of supplementary funds were, in order of frequency, spousal support, part-time employment and savings or pension earnings. The results of the study demonstrated that artists who sold work at markets frequented by tourists were more likely to sustain themselves financially than those selling out of a suburban studio gallery. A stand-out trait for those who indicated economic sustainability was that they treated painting as a full-time job, dedicating meaningful time to business activities outside of the creative practice. The subjective well-being of artists was affected by the need to create artwork with commercial value. Some artists referred to the strain experienced by the need to make a living through creative work and how the economic pressures affected their overall creativity.
