description: One of the most promising space missions of ESA is the astrometric satellite Gaia, which will provide very precise astrometry and multicolour photometry, for all 1.3 billion objects to V~20, and radial velocities with accuracies of a few km/s for most stars brighter than V ~ 17. Consequently, full homogeneous six-dimensional phase-space information for a huge number of stars will become available. Our Monte Carlo simulator has been used to estimate the number of white dwarfs potentially observable by Gaia. From this we assess which would be the white dwarf luminosity functions which Gaia will obtain and discuss in depth the scientific returns of Gaia in the specific field of white dwarf populations. Scientific attainable goals include, among others, a reliable determination of the age of the Galactic disk, a better knowledge of the halo of the Milky Way and the reconstruction of the star formation history of the Galactic disk. Our results also demonstrate the potential impact of a mission like Gaia in the current understanding of the white dwarf cooling theory.

description: The co-occurrence association is widely observed in many empirical data. Mining the information in co-occurrence data is essential for advancing our understanding of systems such as social networks, ecosystem, and brain network. Measuring similarity of entities is one of the important tasks, which can usually be achieved using a network-based approach. Here we show that traditional methods based on the aggregated network can bring unwanted in-directed relationship. To cope with this issue, we propose a similarity measure based on the ego network of each entity, which effectively considers the change of an entity's centrality from one ego network to another. The index proposed is easy to calculate and has a clear physical meaning. Using two different data sets, we compare the new index with other existing ones. We find that the new index outperforms the traditional network-based similarity measures, and it can sometimes surpass the embedding method. In the meanwhile, the measure by the new index is weakly correlated with those by other methods, hence providing a different dimension to quantify similarities in co-occurrence data. Altogether, our work makes an extension in the network-based similarity measure and can be potentially applied in several related tasks.

description: A model Hamiltonian representing the Cu spins in La$_2$CuO$_4$ in its low-temperature body-centred orthorhombic phase, that includes both spin-orbit generated Dzyaloshinskii-Moriya interactions and interplanar exchange, is examined within the RPA utilizing a Tyablikov decoupling of various high-order Green's functions. The magnetic susceptibility is evaluated as a function of temperature and the parameters quantifying these interactions, and compared to recently obtained experimental data of Lavrov, Ando and collaborators. An effective Hamiltonian corresponding to a simple tetragonal structure is shown to reproduce both the magnon spectra and the susceptibility of the more complicated body-centred orthorhombic model.

description: 近年カラオケは世代関係なく普及しており, グループでのカラオケ, ヒトカラな ど, カラオケの楽しみ方は多く存在する. グループでの楽しみ方の一つとして, 主 旋律と副旋律を 2 人で歌ってハーモニーを奏でることがあげられる. しかし副旋律 (いわゆるハモリパート)の練習を行なう際に, 主旋律につられてしまい上手く歌 えない, 曲のキーを変更した場合に副旋律の音高が分からなくなってしまうなど, 副旋律の習得は困難であると考えられる. 既存研究や既存システムには, 相対音感 を鍛えるシステムが存在する. しかし, 音感自体の習得に時間がかかることで副旋 律を歌えるようになるまでに多くの時間を要し, 副旋律の習得が困難であることが 問題であった. 本研究では, 副旋律の歌唱練習を一人で行なえるように, 歌唱練習支援システム を開発した. このシステムは, (1) 副旋律の自動生成機能, (2) 音高表示機能(ユー ザー歌唱の音高を視覚的に表示する機能), (3) ループバック機能(ユーザーの副 旋律の習得状況に応じて, 装着するヘッドホンへの自身の声の返しを変更するよう に促す機能)(4) キー変更機能, の 4 つの機能を持つ. 本論文では, (2)~(4) の有効 性を被験者実験を通じて明らかにする. 被験者実験 1 では, 音高表示機能, ループバック機能により, 主旋律につられな いための練習が可能かどうかを確かめた. ループバックあり+音高表示あり条件 を提案手法とし, 音高表示機能なし条件を比較手法 1, ループバックなし条件を比 較手法 2 とし, 実験を行なった. 主旋律につられるかどうかの設問(0~6 の 7 段階 評価)では, 他の 2 手法よりもわずかに評価が高かったが, 必ずしも十分な差とは言えなかった. この結果が得られた理由として, 実験の時間が短かったことや, シ ステムの音声が MIDI 音源であったためにそもそもつられない状況になかった可 能性が挙げられる. しかし実験後のインタビューでは, 4 名が提案手法が他の手法 に比べて主旋律につられなかったと回答していることから, 音高表示機能は本番で 主旋律につられないための副旋律練習に一定の効果をもたらしている可能性があ る. 習得度(生成された副旋律とユーザーの音高一致率)については, 提案手法で は被験者 10 名中 7 名に習得度の向上が見られたが, 比較手法 1 では 3 名しか向上 が見られなかったことから, ループバック機能と音高表示機能が副旋律の習得に有 効であることがわかった. 実験 2 では, キー変更機能が, 原曲と異なるキーでのハモり習得に有効かどうか を確かめる実験を行なった. キー変更可能条件とキー変更不可能条件を比較し, 検 証を行なった. 本番での副旋律の歌いにくさについての設問(0~6 の 7 段階評価) では, キー変更可能条件が不可能条件よりも評価が 1.3 以上高く, キー変更可能条 件を使用した方がハモりやすいという結果が得られた. 習得度をみると, キー変更 可能条件では, 被験者 12 名中 8 名に習得度の向上が見られたが, キー変更不可能条 件では, 4 名しか向上が見られなかったことから, キー変更機能が副旋律の習得に 有効であることが確かめられた. 以上より, ループバック機能, 音高表示機能は, 主旋律につられないための練習 に一定の効果を持っていることがわかった. また, キー変更機能の必要性, 原曲と 異なるキーでのハモり習得に有効であることが確かめられた.

description: Given S_1, a finite set of points in the plane, we define a sequence of point sets S_i as follows: With S_i already determined, let L_i be the set of all the line segments connecting pairs of points of the union of S_1,...,S_i, and let S_i+1 be the set of intersection points of those line segments in L_i, which cross but do not overlap. We show that with the exception of some starting configurations the set of all crossing points is dense in a particular subset of the plane with nonempty interior. This region is the intersection of all closed half planes which contain all but at most one point from S_1.

description: In this paper, we are interested in the behavior of the typical Poisson-Voronoi cell in the plane when the radius of the largest disk centered at the nucleus and contained in the cell goes to infinity. We prove a law of large numbers for its number of vertices and the area of the cell outside the disk. Moreover, for the latter, we establish a central limit theorem as well as moderate deviation type results. The proofs deeply rely on precise connections between Poisson-Voronoi tessellations, convex hulls of Poisson samples and germ-grain models in the unit ball. Besides, we derive analogous facts for the Crofton cell of a stationary Poisson line process in the plane.

description: Mathematical regularisation of the nonlinear terms in the Navier-Stokes equations provides a systematic approach to deriving subgrid closures for numerical simulations of turbulent flow. By construction, these subgrid closures imply existence and uniqueness of strong solutions to the corresponding modelled system of equations. We will consider the large eddy interpretation of two such mathematical regularisation principles, i.e., Leray and LANS$-α$ regularisation. The Leray principle introduces a {\bfi smoothed transport velocity} as part of the regularised convective nonlinearity. The LANS$-α$ principle extends the Leray formulation in a natural way in which a {\bfi filtered Kelvin circulation theorem}, incorporating the smoothed transport velocity, is explicitly satisfied. These regularisation principles give rise to implied subgrid closures which will be applied in large eddy simulation of turbulent mixing. Comparison with filtered direct numerical simulation data, and with predictions obtained from popular dynamic eddy-viscosity modelling, shows that these mathematical regularisation models are considerably more accurate, at a lower computational cost.

description: Accurate prediction of crop yield supported by scientific and domain-relevant insights, can help improve agricultural breeding, provide monitoring across diverse climatic conditions and thereby protect against climatic challenges to crop production including erratic rainfall and temperature variations. We used historical performance records from Uniform Soybean Tests (UST) in North America spanning 13 years of data to build a Long Short Term Memory - Recurrent Neural Network based model to dissect and predict genotype response in multiple-environments by leveraging pedigree relatedness measures along with weekly weather parameters. Additionally, for providing explainability of the important time-windows in the growing season, we developed a model based on temporal attention mechanism. The combination of these two models outperformed random forest (RF), LASSO regression and the data-driven USDA model for yield prediction. We deployed this deep learning framework as a 'hypotheses generation tool' to unravel GxExM relationships. Attention-based time series models provide a significant advancement in interpretability of yield prediction models. The insights provided by explainable models are applicable in understanding how plant breeding programs can adapt their approaches for global climate change, for example identification of superior varieties for commercial release, intelligent sampling of testing environments in variety development, and integrating weather parameters for a targeted breeding approach. Using DL models as hypothesis generation tools will enable development of varieties with plasticity response in variable climatic conditions. We envision broad applicability of this approach (via conducting sensitivity analysis and "what-if" scenarios) for soybean and other crop species under different climatic conditions.

description: This paper examines the water and sewerage service delivery programs for the poor residents in the MWSS service area. Specifically, it analyzes the pro-poor water programs of the MWCI and MAYNILAD, the private water concessionaires of MWSS, by looking into the mechanisms adopted to expand access of the poor to water and sewerage services, number of hours that water is made available, and pricing/affordability of services. At the end, lessons are drawn from the experience for an improved regulation of the water concession.

description: The Relational Blockworld (RBW) interpretation of non-relativistic quantum mechanics (NRQM) is introduced. Accordingly, the spacetime of NRQM is a relational, non-separable blockworld whereby spatial distance is only defined between interacting trans-temporal objects. RBW is shown to provide a novel statistical interpretation of the wavefunction that deflates the measurement problem, as well as a geometric account of quantum entanglement and non-separability that satisfies locality per special relativity and is free of interpretative mystery. We present RBW's acausal and adynamical resolution of the so-called "quantum liar paradox," an experimental set-up alleged to be problematic for a spacetime conception of reality, and conclude by speculating on RBW's implications for quantum gravity.

description: We study the constraints on reciprocal and non-reciprocal many-body radiative heat transfer imposed by symmetry and the second law of thermodynamics. We show that the symmetry of such a many-body system in general forms a magnetic group, and the constraints of the magnetic group on the heat transfer can be derived using a generalized reciprocity theorem. We also show that the second law of thermodynamics provides additional constraints in the form of a nodal conservation law of heat flow at equilibrium. As an application, we provide a systematic approach to determine the existence of persistent heat current in arbitrary many-body systems.

description: 日本のアニメやアイドルはサブカルチャーとして人気である.アニメの声 優やアイドルによるライブも活発に行われており,ライブやコンサートの総 動員数は年々増えている.こうした声優やアイドルのライブにおいて,観客 からアーティストへ向けた行動として,独特な動きやペンライトを振る動作, 手拍子,掛け声による合いの手が存在する.ライブでの合いの手は比較的新 しい文化であり,また,現状ではサブカルチャーの中でしか注目されていな いため,ライブでの合いの手に関して学術的な観点からの分析・考察があまり されてこなかった.しかし,楽曲中の合いの手に関する特徴が分かれば,合 いの手を入れて観客が能動的に働きかけ,観客とアーティストで相互に盛り 上がる曲を作りやすくすることが期待できる. 本研究では,合いの手が入る楽曲の定量的な調査の第一段階として,声優 のライブにおける合いの手の一種である「PPPH」が入れられている楽曲に 着目する.「PPPH」の入れられている楽曲の特徴を分析することを目的とし, ライブで「PPPH」が入れられている楽曲と入れていない楽曲の音響特徴量を パターン認識的アプローチにより分析する.多数の音響特徴量から特徴量選 択によって選ばれた少数の特徴量を使って「PPPH」有りの楽曲と「PPPH」 無しの楽曲を識別できれば,その特徴量に楽曲の違いが含まれるという考え に基づいて音響特徴量による分類実験を行い,「PPPH」の有無を正しく分類 できるか調べる.分類実験には,実際にライブで「PPPH」が行われている 水樹奈々とアイドルマスターの楽曲を 1 曲ごとに,A(A メロ最後 2 小節を 除く),A’(A メロ最後 2 小節),B(B メロ),C(サビ)の 4 つのセクショ ンに分けて使用する. 分析 1 では,全特徴量から特徴量選択を行って特徴量を 10 個に絞って分類実験を行った.その結果,BPM やコード進行に関連する特徴量が多く選ば れた.分類器で差はあるものの,高いものでは 91%という高い精度を得られ たことから,これらが「PPPH」の有無に関係していると言える. 分析 2 では,全特徴量からフィルターアプローチによって選ばれた特徴量 から影響が強いと考えられる特徴量を種類ごとにまとめて用い,特徴量選択 で特徴量を絞って分類実験を行った.その結果,コード進行に関連する特徴 量での分類は,水樹奈々の楽曲の B と C において 82%,アイドルマスター の楽曲は A’ で 79%と高い分類精度を得られた.これらのことから,コード 進行に関連する特徴量が分類に効果的であると言える. 分析 3 では,アーティスト差を考慮せず全楽曲に対して特徴量選択を行っ た.その結果,上位 10 個の特徴量のうち 8 個が BPM に関連する特徴量だっ たが,1 位にはサビのドミナントコードを表す特徴量が選ばれた.これまで の分析と合わせると,コード進行に関連する特徴量が「PPPH」の有無の分 類に効果的である可能性が高いと言える.また,楽曲の A の特徴量が選ばれ なかったことから,A は「PPPH」の有無には影響しづらいと言える. 分析 4 では,サビのドミナントコードを表す特徴量のみに絞り,水樹奈々 の楽曲,アイドルマスターの楽曲,全楽曲で分類実験を行った.水樹奈々の 楽曲は 77%以上,全楽曲では 70%以上の分類精度を得られた.アイドルマ スターの楽曲は 50%を切るものもあり高い分類精度とは言えないが,全楽曲 では安定した分類精度を得られていることから,サビのドミナントコードが 「PPPH」の有無の分類に関係していると言える. よって,特徴量の中で「PPPH」の有無の分類に特に影響しているのは, コード進行に関連する特徴量であると分かった.また,特に効果的なものは, サビにおけるドミナントコードを表す特徴量だと分かった.

description: We study the integrability of geodesic flow in the background of some recently discovered charged rotating solutions of supergravity in four and five dimensions. Specifically, we work with the gauged multicharge Taub-NUT-Kerr-(Anti) de Sitter metric in four dimensions, and the $U(1)^3$ gauged charged-Kerr-(Anti) de Sitter black hole solution of N = 2 supergravity in five dimensions. We explicitly construct the Killing tensors that permit separation of the Hamilton-Jacobi equation in these spacetimes. These results prove integrability for a large class of previously known supergravity solutions, including several BPS solitonic states. We also derive first-order equations of motion for particles in these backgrounds and examine some of their properties. Finally, we also examine the Klein-Gordon equation for a scalar field in these spacetimes and demonstrate separability.

description: In recent years there has been considerable interest in the relationship between a country's export competitiveness and the role played by technology in strengthening and maintaining competitive advantage. A central feature of recent empirical work, mainly focused on the OECD countries, has rested on examining patterns of export and technological specialisation between economies and sectors. This paper moves attention away from the advanced industrialised economies to examine the trends for trade and technological specialisation among the East Asian developing economies. In particular, two aspects of specialisation are examined. First, to what extent have patterns of competitive advantage changed over time and second, to measure the relationship between patterns of trade and technological specialisation. Important differences are found in the patterns of specialisation, and in the relationship between them among the advanced East Asian economies and those catching up.
The ecology and evolution of behavioral variation in the African antelope and the relevance of behavior for conservation
Creators: name: Brashares, Justin S.
Publisher: name: University of British Columbia
Year: 2009

description: Resource distribution, habitat structure, and predation pressure are thought to be the primary forces driving the evolution of variation in social organization within and between species. I tested several predicted links between ecology and social organization with interand intraspecific comparative examinations of African antelope (family Bovidae). First, for 75 antelope species I tested the hypotheses that dietary selectivity is correlated negatively with (1) body mass and (2) group size, (3) that gregarious species either flee or counter-attack when approached by predators, but that solitary and pair-living species seek cover to hide, and (4) that body mass and group size are correlated positively. My results supported the first three of these hypotheses, but the hypothesis that body mass and group size are related positively was only weakly supported in a phylogenetically corrected analysis. Second, I studied 161 individually identified oribi, Ourebia ourebi, at five sites along an ecological gradient in Ghana, West Africa, to examine correlates of variability in social behavior. Results of uni- and multi-variate analyses showed that forage abundance and quality accounted best for variation in female oribi dispersion among and within study populations. Male territorial behavior differed among sites and was related to female home range size. Using 30 years of historical wildlife count data from six reserves in Ghana, I next asked if behavior, and other traits of 41 species of large African mammals, and geographic characteristics of reserves predispose species to local extinction. I showed that species in isolated populations and monogamous species were particularly prone to extinction. Abundance, fecundity, trophic group, and human hunting preference were unrelated to persistence. Looking at external influences on species persistence I found that ninety-eight percent of the observed variation in extinction rates among Ghana's reserves was accounted for statistically by human population and reserve size. Results also showed that extinction rates were highest for all large mammals near reserve borders. Taken together, these four studies identify the role of ecology in shaping the behavioral variation observed among and within species and they highlight behavioral and other traits that affect the management and conservation of African mammals.

description: We report results from the first comprehensive total quality evaluation of five major indicators in the U.S. Census Bureau's Longitudinal Employer-Household Dynamics (LEHD) Program Quarterly Workforce Indicators (QWI): total flow-employment, beginning-of-quarter employment, full-quarter employment, average monthly earnings of full-quarter employees, and total quarterly payroll. Beginning-of-quarter employment is also the main tabulation variable in the LEHD Origin-Destination Employment Statistics (LODES) workplace reports as displayed in OnTheMap (OTM), including OnTheMap for Emergency Management. We account for errors due to coverage; record-level non-response; edit and imputation of item missing data; and statistical disclosure limitation. The analysis reveals that the five publication variables under study are estimated very accurately for tabulations involving at least 10 jobs. Tabulations involving three to nine jobs are a transition zone, where cells may be fit for use with caution. Tabulations involving one or two jobs, which are generally suppressed on fitness-for-use criteria in the QWI and synthesized in LODES, have substantial total variability but can still be used to estimate statistics for untabulated aggregates as long as the job count in the aggregate is more than 10.

description: This manuscript summarizes a total of 12 peer-reviewed studies, published from 1981 to 2001, reporting 28 separate estimates for the disaggregate2 value of water quality services provided by coastal and non-coastal wetlands. Estimates ranged across three orders of magnitude and are highly dependent on the specific geographic site providing the service, the type of water quality service provided, the measurement technique, and whether locally derived benefits were calculated to extend across all existing wetlands. Considering only coastal zone wetlands across all study categories, the value of water quality services ranged from $2.85/acre/year to $5,673.80/acre/year, with a mean and median of $825.04/acre/year and $210.93/acre/year, respectively. The large difference between the mean and median value reflects the non-normal distribution of the estimates, and in particular the influence of a few very high values. Eliminating the most extreme outliers from the calculations generated mean and median values of $323.05/acre/year and $178.64/acre/year, respectively. By comparison, reported estimates of willingness-to-pay (WTP) values for wetland water quality services were relatively consistent across studies, ranging from $41.71 to $101.81, with a mean and median of $66.59 and $63.19, respectively. The apparent importance of geographic location, and the specific use demand, on water quality service value suggests that this facet of coastal wetland benefits needs to be carefully examined within a spatially disaggregated context.

description: We discuss a parity nonconserving asymmetry in the cross section of KLL dielectronic recombination of polarized electrons on the hydrogen-like ions with $Z \lesssim 60$. This effect is strongly enhanced because of the near-degeneracy of doubly-excited $2l2l'$ states of opposite parity in He-like ions. For ions with $Z \sim 30$ the asymmetry is of the order of $10^{-9}$. For $Z \approx 48$ a level crossing takes place, leading to the PNC asymmetry of $\pm 5\times 10^{-9}$, which is $10^8$ times greater than the basic strength of the weak interaction in atoms.

Subjects: subject: Quantum Physics (quant-ph)

description: We provide the first solution of a time-dependent metric operator for the non-Hermitian Jaynes-Cummings Hamiltonian. We use this solution to calculate the entanglement between two identical isolated such Hamiltonians. The presence of a non-Hermitian interaction term leads to a spontaneously broken $\mathcal{PT}$-symmetric regime which manifests itself in the exotic time-evolution of entanglement. When the symmetry is broken, oscillatory modes transition into decay. As such that there is a drastic difference in behaviour between the broken and unbroken regimes.

Resource /Energy Economics and Policy

description: If the technology in a multi-species fishery is such that there is jointness in inputs and non-separability between inputs and outputs, then management on a species-by-species basis may lead to unintended outcomes, including over-exploitation of the resource. This study investigates the nature of the technical and economic relationships underlying the 1989-1990 Mauritanian cephalopod fishery by estimating a system of dual output supply functions derived from a generalized Leontief revenue function. Model results indicate the existence of jointness in inputs and non-separability between inputs and outputs in the fishery. Cross-price elasticities indicated a number of substitute and complementary relationships, with these relationships changing in magnitude across years. Taken together, the results suggest that any attempts to economically manage the resource should be based on multi-product production theory, not single-species biological response functions. Besides ruling out single-species management, the dominance of substitute relationships in the Mauritanian cephalopod fishery precludes the use of "key species" management of the entire resource.

description: This manuscript summarizes a total of 12 peer-reviewed studies, published from 1978 to 2001, reporting 32 separate estimates for the disaggregate2 value of hunting and fishing services provided by coastal and non-coastal wetlands. Estimates ranged across three orders of magnitude and are highly dependent on the specific geographic site providing the service, the target species of the hunting and fishing activity, and the measurement technique. Considering only coastal zone wetlands across all study categories, the value of wetlands to single-target hunting and fishing (oysters, menhaden, etc.) ranged from $1.05/acre/year to $663.74/acre/year, with a mean and median of $113.95/acre/year and $10.03/acre/year, respectively. Considering only coastal zone wetlands across all study categories, the value of wetlands to aggregate hunting or fishing (both commercial and recreational) ranged from $16.76/acre/year to $1,025.03/acre/year, with a mean and median of $233.37/acre/year and $106.54/acre/year, respectively. By comparison, the range of reported estimates of willingness-to-pay (WTP) values for recreational hunting and fishing services were somewhat more narrowly bounded across studies, ranging $83.99 to $616.46, with a mean and median of $303.67 and $207.79, respectively. The importance of a wetlands geographic location, its relationship to the target fishery or animal species, and the differing relationships with commercial and recreational consumptive users suggests that coastal wetland benefits need to be carefully examined within a spatially disaggregated context.

description: This work deals with cosmological models driven by real scalar field, described by standard dynamics in generic spherical, flat, and hyperbolic geometries. We introduce a first-order formalism, which shows how to relate the potential that specifies the scalar field model to Hubble's parameter in a simple and direct manner. Extensions to tachyonic dynamics, and to two or more real scalar fields are also presented.

description: We study a one-dimensional (iso)spin 1/2 Bose gas with repulsive delta-function interaction by the Bethe Ansatz method and discuss the excitations above the polarized ground state. In addition to phonons the system features spin waves with a quadratic dispersion. We compute analytically and numerically the effective mass of the spin wave and show that the spin transport is greatly suppressed in the strong coupling regime, where the isospin-density (or ``spin-charge'') separation is maximal. Using a hydrodynamic approach, we study spin excitations in a harmonically trapped system and discuss prospects for future studies of two-component ultracold atomic gases.

Dissipation in Pulsar Winds

description: I review the constraints placed on relativistic pulsar winds by comparing optical and X-ray images of the inner Crab Nebula on the one hand with two-dimensional MHD simulations on the other. The various proposals in the literature for achieving the low magnetisation required at the inner edge of the Nebula, are then discussed, emphasising that of dissipation in the striped-wind picture. The possibility of direct observation of the wind is examined. Based on the predicted orientation of the polarisation vector, I outline a new argument suggesting that the off-pulse component of the optical emission of the Crab pulsar originates in the wind.

Subjects: Resource /Energy Economics and Policy

description: This paper is the first in a planned series that seeks to synthesize and describe many of the economic questions that arise when attempting to develop groundwater and surface water management policy in Louisiana. In this series, current economic perspectives on water policy will be drawn from the technical and policy literature, with particular emphasis placed on the challenge of coordinating tradeoffs among different water users. While these reports will not attempt an exhaustive review of the broad water management literature, a comprehensive discussion of economic-based water management is a primary goal. In addition, the series will try to avoid focusing on a specific policy approach, but instead detail the issues and policy options that are often confronted when managing water resources. This information should help to frame water management issues within a broader resource-economics context and provide a basis for the development of enlightened management policy.

description: We present high-precision experimental and numerical studies of the Nusselt number $Nu$ as functions of the Rayleigh number $Ra$ in geostrophic rotating convection with domain aspect ratio $Γ$ varying from 0.4 to 3.8 and the Ekman number Ek from $2.0{\times}10^{-7}$ to $2.7{\times}10^{-5}$. The heat-transport data $Nu(Ra)$ reveal a gradual transition from buoyancy-dominated to geostrophic convection at large $Ek$, whereas the transition becomes sharp with decreasing $Ek$. We determine the power-law scaling of $Nu{\sim}Ra^γ$, and show that the boundary flows give rise to pronounced enhancement of $Nu$ in a broad range of the geostrophic regime, leading to reduction of the scaling exponent $γ$ in small $Γ$ cells. The present work provides new insight into the heat-transport scaling in geostrophic convection and may explain the discrepancies observed in previous studies.

Closed string tachyons, flips and conifolds

Year: 2005
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Following the analysis of tachyons and orbifold flips described in hep-th/0412337, we study nonsupersymmetric analogs of the supersymmetric conifold singularity and show using their toric geometry description that they are nonsupersymmetric orbifolds of the latter. Using linear sigma models, we see that these are unstable to localized closed string tachyon condensation and exhibit flip transitions between their two small resolutions (involving 2-cycles), in the process mediating mild dynamical topology change. Our analysis shows that the structure of these nonsupersymmetric conifolds as quotients of the supersymmetric conifold obstructs the 3-cycle deformation of such singularities, suggesting that these nonsupersymmetric conifolds decay by evolving towards their stable small resolutions.

description: This manuscript summarizes a total of 8 peer-reviewed studies, published from 1975 to 2001, reporting 24 separate estimates for the disaggregate2 value of habitat and species protection services provided by coastal and non-coastal wetlands. Estimates varied within a single order of magnitude and were fairly tightly bounded. Considering only coastal zone wetlands across all study categories, the value of habitat and species protection ranged from $168.96/acre/year to $403.16/acre/year, with a mean and median of $249.44/acre/year and $253.47/acre/year, respectively. By comparison, reported estimates of willingness-to-pay (WTP) values for wetland habitat and species protection services ranged from a low of $30.12 to $434.67, with a mean and median of $211.59 and $213.86, respectively. Geographic location and type of wetland appeared to have a relatively minor impact on the estimated values.
Where Are All The Fallback Disks? Constraints on Propeller Systems

description: Fallback disks are expected to form around new-born neutron stars following a supernova explosion. In almost all cases, the disk will pass through a propeller stage. If the neutron star is spinning rapidly (initial period $\sim 10$ ms) and has an ordinary magnetic moment ($\sim 10^{30}$ G cm$^3$), the rotational power transferred to the disk by the magnetic field of the neutron star will exceed the Eddington limit by many orders of magnitude, and the disk will be rapidly disrupted. Fallback disks can thus survive only around slow-born neutron stars and around black holes, assuming the latter do not torque their surrounding disks as strongly as do neutron stars. This might explain the apparent rarity of fallback disks around young compact objects.

description: The small sample performance of Granger causality tests under different model dimensions, degree of cointegration, direction of causality, and system stability are presented. Two tests based on maximum likelihood estimation of error-correction models (LR and WALD) are compared to a Wald test based on multivariate least squares estimation of a modified VAR (MWALD). In large samples all test statistics perform well in terms of size and power. For smaller samples, the LR and WALD tests perform better than the MWALD test. Overall, the LR test outperforms the other two in terms of size and power in small samples.

description: Co and Na NMR are used to probe the local susceptibility and charge state of the two Co sites of the Na-ordered orthorhombic Na0.5CoO2. Above T_N=86K, both sites display a similar T-dependence of the spin shift, suggesting that there is no charge segregation into Co3+ and Co4+ sites. Below T_N, the magnetic long range commensurate order found is only slightly affected by the metal-insulator transition (MIT) at T_MIT=51K. Furthermore, the electric field gradient at the Co site does not change at these transitions, indicating the absence of charge ordering. All these observations can be explained by successive SDW induced by two nestings of the Fermi Surface specific to the x=0.5 Na-ordering.
