Subsistence of Neolithic Pearl River Estuary area, South China
Creators: name: Li, Guo
Publisher: name: University of British Columbia
Year: 2009

description: The thesis is a study of the subsistence of the Pearl River Estuary (abbreviated as PRE) area in the southernmost Mainland China during the Neolithic (6,000-3,500 BP). Despite poor preservation of organic subsistence material in this (sub) tropical and coastal area, important Neolithic sites, artifacts and faunal remains have been unearthed in recent years. Some new methods such as isotopic analysis have been employed. To make good use of the data and make up for the geographic disadvantage in preservation, it is attempted in this thesis to summarize and interpret available archaeological material, coupled with site catchment analysis, to address the subsistence. First, the subsistence of the Early Neolithic of Lingnan is discussed, and used as a fore-scene to suggest the PRE subsistence appearing later in the Middle Neolithic. Second, ecofact, artifact and site data of the PRE (Middle/Late Neolithic) are synthesized, serving as a solid but limited factual foundation for assessing the subsistence. Finally, site catchment analysis is used to enhance or mutually verify with the empirical material, or to provide new lines of reference. Ecological data are integrated wherever possible. The conclusion is that the Neolithic subsistence of the PRE would have been generally foraging based, particularly fishing and mollusk collecting. However, farming would have been playing more and more important role, especially during the Late Phase of the Late Neolithic (4,300-3,500 BP), with probable economic and political interactions with rice farming cultures, increase of sedentism, exchange and population, and of social competition with other groups in South China. The PRE case tends to confirm to the understanding that even though farming skill was mastered, if foraging resources were rich and handy, foraging would have prevailed and farming might have been maintained to the minimum just as a supplement.

description: The filling length of an edge-circuit ηin the Cayley 2-complex of a finite presentation of a group is the least integer L such that there is a combinatorial null-homotopy of ηdown to a base point through loops of length at most L. We introduce similar notions in which the null-homotopy is not required to fix a basepoint, and in which the contracting loop is allowed to bifurcate. We exhibit groups in which the resulting filling invariants exhibit dramatically different behaviour to the standard notion of filling length. We also define the corresponding filling invariants for Riemannian manifolds and translate our results to this setting.

description: We present spectroscopic ages, metallicities, and [alpha/Fe] ratios for 70 globular clusters in M31 that were derived from Lick line-index measurements. In addition to a population of old (>10 Gyr) globular clusters with a wide range of metallicities, from about -2.0 dex to solar values, we find evidence for a population of intermediate-age globular clusters with ages between ~5 and 8 Gyr and a mean metallicity around [Z/H]=-0.6. We also confirm the presence of young M31 globular clusters that were recently identified by Beasley et al. (2004), which have ages <1 Gyr and relatively high metallicities around -0.4 dex. The M31 globular cluster system has a clearly super-solar mean [alpha/Fe]=0.14\pm0.04 dex. Intermediate-age and young objects show roughly solar abundance ratios. We find evidence for an age-[alpha/Fe] relation in the sense that younger clusters have smaller mean [alpha/Fe] ratios. From a comparison of indices, mostly sensitive to carbon and/or nitrogen abundance, with SSP model predictions for nitrogen-enhanced stellar populations, we find a dichotomy in nitrogen enhancement between young and old M31 globular clusters. The indices of objects older than 5 Gyr are consistent with a factor of three or higher in nitrogen enhancement compared to their younger counterparts. Using kinematical data from Morrison et al. (2004) we find that the globular cluster sub-population with halo kinematics is old (>9 Gyr), has a bimodal metallicity distribution, and super-solar [alpha/Fe]. Disk globular clusters have a wider range of ages, are on average more metal-rich, and have a slightly smaller mean [alpha/Fe] ratio. (abridged)

description: ギターは趣味として人気の楽器である.ギターに挑戦する人は多いが,いざ手 に取ってみると,弦を正しく押さえることが難しく,ここで挫折してしまう人も 多い.その要因としては,正しい位置で押さえられていないことや,触れてはい けない弦に誤って触れてしまっていることが考えられる.初心者にとって,その ような状態になっていることに気付きにくく,正しく押さえることが難しく感じ ることが課題になっていると考えられる. 本研究では,ギターの弦を押さえた時に正しくギターコードを押さえられている かどうかを判定して,ユーザにフィードバックする支援システムを開発する. 本システムは,弦を押さえた時に圧力のかかる位置と弦に触れているかどうかを判定し, その判定結果をユーザにフィードバックする.圧力のかかる位置の判定は接触位置セ ンサをギター本体と各弦の間に挟み込み,弦に触れているかどうかの判定は静電容 量センサを各弦に接続して静電容量を検出することで実現する.実装には,ギター本 体にセンサと接続したArduinoを取り付け,そのArduinoとProcessingを連携する ことで,ユーザにProcessingの描画機能を用いたフィードバックする.練習対象とし ては,ギターの主要コード14種類(C,D,E,F,G,A,B,Cm,Dm,Em,Fm,Gm,Am,Bm) のうち,バレーコードの含まないものに限定している. 評価実験は,本システムを用いてギターの練習をしたときに,ギター演奏能力 に向上が見られるかどうかを確認するための実験を 2 種類を行った.片方は短時 間の間での練習効果を確認する短期実験で,もう片方は一定期間本システムを使 い続けた場合の効果を確認するための長期貸与実験を行った.短期実験では,3 名の協力者に,指定したギターコードを 20 分間ずつ支援システムを搭載したアコー スティックギターと通常のアコースティックギターで練習してもらった.また,そ れぞれの練習が終わったタイミングで通常のアコースティックギターで正しく押さ えられているか,その時の押さえ方で正しい音が出るかの確認を行った.最後に, アンケートに回答してもらった.正しい音が出るかの確認を行った結果としては, いずれも有意な差が見られなかったが,アンケートの回答結果からは,触れては いけない弦に触れてしまった時にすぐに分かったかどうかの質問において,平均 点がシステム搭載ギターでは 5.00 点,通常のギターのみでは 2.67 点で大きな差が あり,有用であると考えられた.長期貸与実験では,2 名の協力者に,2 週間の間, システムを搭載したアコースティックギターと通常のアコースティックギターを貸 与し,ギターコード貸与期間中に 1 日に最低 15 分の練習実験を行ってもらった. その結果,実験開始から回収時までで,日数を重ねるごとに 1 分辺りにコードを 正しく成功させる数が増えており,演奏能力が向上したことが分かった.また,ア ンケートの結果からも,システム搭載ギターのフィードバック機能は有用である と考えられた.

description: Brain-inspired computing concepts like artificial neural networks have become promising alternatives to classical von Neumann computer architectures. Photonic neural networks target the realizations of neurons, network connections and potentially learning in photonic substrates. Here, we report the development of a nanophotonic hardware platform of fast and energy-efficient photonic neurons via arrays of high-quality vertical cavity surface emitting lasers (VCSELs). The developed $5\times5$ VCSEL arrays provide high optical injection locking efficiency through homogeneous fabrication combined with individual control over the laser wavelengths. Injection locking is crucial for the reliable processing of information in VCSEL-based photonic neurons, and we demonstrate the suitability of the VCSEL arrays by injection locking measurements and current-induced spectral fine-tuning. We find that our investigated array can readily be tuned to the required spectral homogeneity, and as such show that VCSEL arrays based on our technology can act as highly energy efficient and ultra-fast photonic neurons for next generation photonic neural networks. Combined with fully parallel photonic networks our substrates are promising for ultra-fast operation reaching 10s of GHz bandwidths, and we show that a nonlinear transformation based on our lasers will consume only about 100 fJ per VCSEL, which is highly competitive, compared to other platforms.

description: Relationships between cotton export sales and export shipments are examined, and a quarter-specific lag structure is estimated. Two econometric systems are estimated, one employing export shipments and the other using export sales. Results indicate that sales are more sensitive to changes in economic variables than shipments and that stocks net of outstanding export sales are more responsive to price and interest rate changes than gross stocks. Sales and shipments are different variables and cannot substitute for one another in econometric modelling. Use of export sales data should be considered in estimation of export demand and stock demand parameters.

description: Groups are the most common association of galaxies in the Universe, found in different configuration states such as loose, compact and fossil groups. We have studied the galaxy group MKW 4s, dominated by the giant early-type galaxy NGC 4104 at z=0.0282. Our aim was to understand the evolutionary stage of this group and to place it within the framework of the standard LambdaCDM cosmological scenario. We have obtained deep optical data with CFHT/Megacam (g and r bands) and we have applied both the galfit 2D image fitting program and the IRAF/ellipse 1D radial method to model the brightest group galaxy (BGG) and its extended stellar envelope. We have also analysed publicly available XMM-Newton and Chandra X-ray data. From N-body simulations of dry-mergers with different mass ratios of the infalling galaxy, we could constrain the dynamical stage of this system. Our results show a stellar shell system feature in NGC 4104 and an extended envelope that was reproduced by our numerical simulations of a collision with a satellite galaxy about 4--6 Gyr ago. The initial pair of galaxies had a mass ratio of at least 1:3. Taking into account the stellar envelope contribution to the total r band magnitude and the X-ray luminosity, MKW 4s falls into the category of a fossil group. Our results show that we are witnessing a rare case of a shell elliptical galaxy in a forming fossil group.

Subjects: Political Economy

description: The 1986 Tax Reform Act established a first year $10,000 expensing option and, for most farm equipment, a 7-year depreciation schedule. Under a profit maximization criterion, these tax law features can lead to multiple optima dependent upon discount and marginal tax rates. For example, the economically efficient time to reinvest under a 2 percent after tax discount rate is at 4, 8, and 30 years for the grower in a 33 percent tax bracket. Thus, the profit maximization behavioral rule needs to be supplemented with knowledge about a farmer's objectives in order to select the "correct" optimal reinvestment interval.

We briefly review the phenomenology of 3-neutrino mixing, and the current data on the 3-neutrino mixing parameters. The open questions and the main goals of future research in the field of neutrino mixing and oscillations are outlined. The predictions for the effective Majorana mass || in neutrinoless double beta (bb0nu-) decay in the case of 3-neutrino mixing and massive Majorana neutrinos are reviewed. The physics potential of the experiments, searching for bb0nu-decay and having sensitivity approximately 10 times better than the presently reached, for providing information on the type of the neutrino mass spectrum, on the absolute scale of neutrino masses and on the Majorana CP-violation phases in the PMNS neutrino mixing matrix, is discussed.

The most important quality factors determining the value of rough rice are head yield and peck. A one percentage point reduction in peck damage raises the price received per hundredweight of rough rice by $.13 to $.68 across markets and years. Since peck damage can be reduced by controlling the rice stinkbug, evaluation of alternative methods for better control of this pest in Texas rice fields is needed.

description: The economic feasibility of investing in sprinkler irrigation technology for rice production is investigated using linear programming and capital budgeting to identify the net annual benefits and net present value, respectively. Groundwater and both flat rate and volumetrically priced surface water sources of irrigation water are analyzed. Under typical practices occurring in rice production operations in the Texas Rice Belt, sprinkler irrigation technology is not profitable at current water costs. Producers using volumetrically priced surface water have the greatest incentive to consider sprinkler irrigation, but water prices must increase by over 250 percent for the investment in a sprinkler irrigation system to become attractive. Yield reductions associated with sprinkle-irrigated rice are a significant disincentive. For equivalent flood and sprinkle-irrigated rice yields, an increase in water prices of over 175 percent is required before the investment in a sprinkler irrigation system becomes economically feasible.
HII and H2 in the envelopes of cooling flow central galaxies

description: We report observations of ionized and warm molecular gas in the extended regions of the central galaxies in several cooling flow clusters. These show that both gas phases are present in these clusters to large radii. We trace both Pa alpha and H2 lines to radii in excess of 20 kpc. The surface brightness profiles of the two phases trace each other closely. Apart from very close to the central AGN, line ratios in and between the phases vary only slowly with position. The kinematics of the phases are indistinguishable and away from the influence of the central AGN both the mean and dispersion in velocity are low (<= 100 km/s) ruling out kinematic support of the molecular gas. All of the above indicates that the mechanisms for heating the molecular gas and ionizing the HII regions are highly coupled. The highest surface brightness emission within a few kpc of the central AGN is distinct, both kinematically and thermally from that at larger radii. The relative strengths of the Pa alpha to the H2 lines indicates a source of UV excitation rich in EUV relative to FUV photons, e.g. a black body with a temperature >= 10^5 K.

description: Scientists aim to extract simplicity from observations of the complex world. An important component of this process is the exploration of data in search of trends. In practice, however, this tends to be more of an art than a science. Among all trends existing in the natural world, one-dimensional trends, often called sequences, are of particular interest as they provide insights into simple phenomena. However, some are challenging to detect as they may be expressed in complex manners. We present the Sequencer, an algorithm designed to generically identify the main trend in a dataset. It does so by constructing graphs describing the similarities between pairs of observations, computed with a set of metrics and scales. Using the fact that continuous trends lead to more elongated graphs, the algorithm can identify which aspects of the data are relevant in establishing a global sequence. Such an approach can be used beyond the proposed algorithm and can optimize the parameters of any dimensionality reduction technique. We demonstrate the power of the Sequencer using real-world data from astronomy, geology as well as images from the natural world. We show that, in a number of cases, it outperforms the popular t-SNE and UMAP dimensionality reduction techniques. This approach to exploratory data analysis, which does not rely on training nor tuning of any parameter, has the potential to enable discoveries in a wide range of scientific domains. The source code is available on github and we provide an online interface at \url{http://sequencer.org}.

Archaeological approaches to ritual in the Andes : a ceramic analysis of ceremonial space at the formative period site of Chiripa, Bolivia
Creators: name: Roddick, Andrew P.
Publisher: name: University of British Columbia
Year: 2009

description: This study uses ceramic data to examine the function of two Middle Formative Period (800-200 BC) structures at the site of Chiripa, in the Lake Titicaca Basin, Bolivia. I investigate the activities that occurred in both domestic and ritual architecture. I also examine the nature of the Yaya-Mama Religious Tradition; a ritual tradition posited for the Lake Titicaca region and thought to be represented by the Chiripa architecture and associated artifact assemblages. The likelihood and nature of feasting and exchange at Chiripa during the Middle Formative Period are also investigated by classifying the ceramic data into both serving and non-serving groups. Previous researchers have suggested that Chiripa structures were used for ritual activity, but their exact nature remains unclear. Also, suggestions that large-scale feasting activity occurred at Chiripa are not supported by the data analyzed here. A general lack of ceramic imports suggests that the Yaya-Mama Tradition was a politically autonomous yet community inclusive tradition at Chiripa, and the site was not the center of a complex polity. I finish by situating my ceramic functional analysis within the context of ethnographic and ethnohistoric studies of ritual and the continuum of developing complexity in the Lake Titicaca Basin. This study demonstrates that the site of Chiripa, in the process of developing complexity, maintained consistent ritual cannons over four centuries of political change; an idea central to religious traditions.

description: The Kondo problem, for a quantum dot (QD), subjected to an external bias, is analyzed in the limit of infinite Coulomb repulsion by using a consistent equations of motion method based on a slave-boson Hamiltonian. Utilizing a strict perturbative solution in the leads-dot coupling, T, to T^4 and T^6 orders, we calculate the QD spectral density and conductance, as well as the decoherent rate that drive the systemm from the strong to the weak coupling regime. Our results indicate thet the weak coupling regime is reached for voltages larger than a few units of the Kondo temperature.

description: This paper outlines an evolutionary theory of adaptive growth based on the twin principles of enterprise and the co-ordinating role of markets. The central organising idea is that economies never grow without simultaneous development. Growth as conventionally understood is a product of structural change and economic self-transformation, and these processes are closely connected with but not reducible to the growth of knowledge. The dominant theme is enterprise, the variations it generates, and the multiple connections between investment, innovation, demand and structural transformation. We explore the dependence of macroeconomic productivity growth on the diversity of technical progress functions and income elasticities of demand at the industry level, and the resolution of this diversity into patterns of economic change through market processes. We show how industry growth rates are emergent phenomena, constrained by higher order processes of emergence that convert an ensemble of industry growth rates into an aggregate rate of growth. The growth of productivity, output and employment are determined mutually and endogenously, and their values depend on the variation in the primary causal influences in the system.
The kinematics of massive quiescent galaxies at $1.4 < z < 2.1$: dark matter fractions, IMF variation, and the relation to local early-type galaxies

description: We study the dynamical properties of massive quiescent galaxies at $1.4 < z < 2.1$ using deep Hubble Space Telescope WFC3/F160W imaging and a combination of literature stellar velocity dispersion measurements and new near-infrared spectra obtained using KMOS on the ESO VLT. We use these data to show that the typical dynamical-to-stellar mass ratio has increased by $\sim$0.2 dex from $z = 2$ to the present day, and investigate this evolution in the context of possible changes in the stellar initial mass function (IMF) and/or fraction of dark matter contained within the galaxy effective radius, $f_\mathrm{DM}$. Comparing our high-redshift sample to their likely descendants at low-redshift, we find that $f_\mathrm{DM}$ has increased by a factor of more than 4 since $z \approx 1.8$, from $f_\mathrm{DM}$ = $6.6\pm1.0$% to $\sim$24%. The observed increase appears robust to changes in the methods used to estimate dynamical masses or match progenitors and descendants. We quantify possible variation of the stellar IMF through the offset parameter $α$, defined as the ratio of dynamical mass in stars to the stellar mass estimated using a Chabrier IMF. We demonstrate that the correlation between stellar velocity dispersion and $α$ reported among quiescent galaxies at low-redshift is already in place at $z = 2$, and argue that subsequent evolution through (mostly minor) merging should act to preserve this relation while contributing significantly to galaxies overall growth in size and stellar mass.

description: We use unbiased computational methods to elucidate the onset and properties of pair superfluidity in two-species fermionic and bosonic systems with onsite interspecies attraction loaded in one-dimensional optical lattice. We compare results from quantum Monte Carlo (QMC) and density matrix renormalization group (DMRG), emphasizing the one-to-one correspondence between the Drude weight tensor, calculated with DMRG, and the various winding numbers extracted from the QMC. Our results show that, for any nonvanishing attractive interaction, pairs form and are the sole contributors to superfluidity, there are no individual contributions due to the separate species. For weak attraction, the pair size diverges exponentially, i.e. Bardeen-Cooper-Schrieffer (BCS) pairing requiring huge systems to bring out the pair-only nature of the superfluid. This crucial property is largely overlooked in many studies, thereby misinterpreting the origin and nature of the superfluid. We compare and contrast this with the repulsive case and show that the behavior is very different, contradicting previous claims about drag superfluidity and the symmetry of properties for attractive and repulsive interactions. Finally, our results show that the situation is similar for soft core bosons: superfluidity is due only to pairs, even for the smallest attractive interaction strength compatible with the largest system sizes that we could attain.

An Unsplit Godunov Method for Ideal MHD via Constrained Transport
Creators: name: Gardiner, Thomas A.
name: Stone, James M.
Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We describe a single step, second-order accurate Godunov scheme for ideal MHD based on combining the piecewise parabolic method (PPM) for performing spatial reconstruction, the corner transport upwind (CTU) method of Colella for multidimensional integration, and the constrained transport (CT) algorithm for preserving the divergence-free constraint on the magnetic field. We adopt the most compact form of CT, which requires the field be represented by area-averages at cell faces. We demonstrate that the fluxes of the area-averaged field used by CT can be made consistent with the fluxes of the volume-averaged field returned by a Riemann solver if they obey certain simple relationships. We use these relationships to derive new algorithms for constructing the CT fluxes at grid cell corners which reduce exactly to the equivalent one-dimensional solver for plane-parallel, grid-aligned flow. We show that the PPM reconstruction algorithm must include multidimensional terms for MHD, and we describe a number of important extensions that must be made to CTU in order for it to be used for MHD with CT. We present the results of a variety of test problems to demonstrate the method is accurate and robust.

description: Increasing numbers of ethical trade initiatives are being launched, reflecting concerns about the limited benefits that globalisation brings to producers in developing countries. Ethical trade is an information-intensive activity yet little is known about the role of information systems in supporting this activity. Ethical trade - with its voluntary codes and consumer campaigns - also represents a new approach to interaction between market actors. This form of self-regulation is seen as an alternative to state regulation and sanctions, and more appropriate to a liberalised international economy. This paper provides a summary of the literature concerning ethical trade, selfregulation and the role of information. It presents models and issues in relation to both ethical trade information systems and information and communication technologies. Findings about information systems and ethical trade also advance our understanding of self-regulation.
A Twin Higgs Model from Left-Right Symmetry

description: We present twin Higgs models based on the extension of the Standard Model to left-right symmetry that protect the weak scale against radiative corrections up to scales of order 5 TeV. In the ultra-violet the Higgs sector of these theories respects an approximate global symmetry, in addition to the discrete parity symmetry characteristic of left-right symmetric models. The Standard Model Higgs field emerges as the pseudo-Goldstone boson associated with the breaking of the global symmetry. The parity symmetry tightly constrains the form of radiative corrections to the Higgs potential, allowing natural electroweak breaking. The minimal model predicts a rich spectrum of exotic particles that will be accessible to upcoming experiments, and which are necessary for the cancellation of one-loop quadratic divergences. These include right-handed gauge bosons with masses not to exceed a few TeV and a pair of vector-like quarks with masses of order several hundred GeV.

The Institutional Policy Framework for Regulation and Competition in Sri Lanka

Year: 2002
Subjects: Public Economics

description: The liberalization of the Sri Lankan economy in 1977 and the privatization of state enterprises in the ensuing years, created a need for competition policy and rules-based regulatory systems to address distributional concerns. However, the integration of these newer external regulatory processes into the policy framework was slow due to an ongoing civil war, pressures to finance the burgeoning fiscal deficit and the related move to opt for rapid privatization. In addition, the policy and governance milieu, institutional structures, and legal framework within which these reforms were finally formulated and implemented did not allow for an effective competition and regulatory regime. This paper describes and analyzes the policy, institutional and legal framework for competition and regulation in Sri Lanka, placing them in the context of pervasive bad governance practices. It is argued that rampant political capture is the principal obstacle to the creation of effective competition and regulatory agencies. The paper also poses the following questions - how to build effective competition and regulatory institutions and systems and to create the conditions for good regulatory governance in a milieu where bad governance is omnipresent; should the competition and regulation reform process rely more on a "market approach" to the delivery of public interest; can such an approach actually guarantee insulation from political influence, given that vested interests with political connections are not confined to the state sector alone; and what impact will such an approach have on equitable growth and poverty alleviation - and suggests that these should form the basis for the Sri Lankan component of the CRC competition, regulation, and regulatory governance research and capacity building program over the next few years.
