description: Chiral light-matter interactions have been investigated for two centuries, leading to the discovery of many chiroptical processes used for discrimination of enantiomers. Whereas most chiroptical effects result from a response of bound electrons, photoionization can produce much stronger chiral signals that manifest as asymmetries in the angular distribution of the photoelectrons along the light propagation axis. Here we implement a self-referenced attosecond photoelectron interferometry to measure the temporal profile of the forward and backward electron wavepackets emitted upon photoionization of camphor by circularly polarized laser pulses. We found a delay between electrons ejected forward and backward, which depends on the ejection angle and reaches 24 attoseconds. The asymmetric temporal shape of electron wavepackets emitted through an autoionizing state further reveals the chiral character of strongly-correlated electronic dynamics.
Reflexive and volitional orienting in children and adults : pointing to a new future
Creators: name: Ristic, Jelena
Publisher: name: University of British Columbia
Year: 2009

description: Traditionally, volitional attention has been studied in the Posner cuing paradigm by using central spatially predictive arrows as attentional cues. The important assumption underlying this methodology has been that arrows (and other central attentional cues) orient attention spatially only if they predict where the target is likely to appear. Recent studies, however, indicate that this fundamental assumption underlying the classic methodology is mistaken. Several studies now report that a range of central directional cues, including arrows, can trigger reflexive orienting effects in both young children and adults when they do not predict where the target is likely to appear. This fact raises the question of whether past studies, using predictive central arrows as attentional cues, were measuring (1) volitional attention because the arrows were predictive, (2) reflexive attention because the arrows were directional, or (3) some combination of volitional and reflexive attention. This issue was investigated in two studies. The first study is presented in Chapter 1. This investigation tested adults with (1) predictive arrow cues (2) nonpredictive arrow cues, to get a pure measure of reflexive orienting, and (3) predictive nondirectional cues, to get a pure measure of volitional orienting. The results of this first study showed that the magnitude of orienting observed with predictive arrow cues was always larger than the s um of pure reflexive and voluntary orienting, suggesting that the traditional measure reflects an interaction between reflexive and volitional attention. The second study, presented in Chapter 2, tested children between the ages of 3 and 6 in a conditions comparable to those in the first study with adults. The results showed that pure reflexive orienting was adult-like, but volitional orienting was not. Young children, unlike adults, could sustain volitional attention for only a brief period of time. Moreover, and also unlike adults, reflexive and volitional orienting appeared to be additive rather than interactive. It is suggested that collectively these findings are consistent with the fields' current understanding of the maturation of brain regions thought to mediate reflexive and volitional orienting.

description: In superconducting circuits with interbit untunable (e.g., capacitive) couplings, ideal local quantum operations cannot be exactly performed on individual Josephson qubits. Here we propose an effective dynamical decoupling approach to overcome the "fixed-interaction" difficulty for effectively implementing elemental logical gates for quantum computation. The proposed single-qubit operations and local measurements should allow testing Bell's inequality with a pair of capacitively-coupled Josephson qubits. This provides a powerful approach, besides spectral-analysis [Nature \textbf{421}, 823 (2003); Science \textbf{300}, 1548 (2003)], to verify the existence of macroscopic quantum entanglement between two fixed-coupling Josephson qubits.

description: This paper reports results from a field experiment in Uganda. The proportion of children five years and younger who slept under a mosquito net was 20 percent higher when nets were distributed for free compared to when an equivalent cash transfer could be used to purchase nets. This effect is attributable to the endowment effect (more nets were retained when received for free than offered for sale), and to differences in how purchased and free nets are allocated within the household. Nets received for free were more likely to be used by young children. Purchased nets, on the other hand, were used by those members of the household, often adults, perceived by participants to suffer from malaria most frequently. When a married woman acquired nets, the probability that her children used these increased with the educational attainment of her husband.

description: In this paper, we extend Grossmann and Lohse's (GL) model [Phys. Rev. Lett. {\bf 86}, 3316 (2001)] for the predictions of Reynolds number (Re) and Nusselt number (Nu) in turbulent Rayleigh-Bénard convection (RBC). Towards this objective, we use functional forms for the prefactors of the dissipation rates in the bulk and the boundary layers. The functional forms arise due to inhibition of nonlinear interactions in the presence of walls and buoyancy compared to free turbulence, along with a deviation of viscous boundary layer profile from Prandtl-Blasius theory. We perform 60 numerical runs on a three-dimensional unit box for a range of Rayleigh numbers (Ra) and Prandtl numbers (Pr) and determine the aforementioned functional forms using machine learning. The revised predictions are in better agreement with the past numerical and experimental results than those of the GL model, especially for extreme Prandtl numbers.

El modelo, derivado del análisis de costes de transacción, desarrollado principalmente por Williamson, se formula como una función tobit que se estima con datos de la industria del vino en la denominación de origen calificada (DOC) de Rioja. También se ha establecido la naturaleza de la relación entre la calidad del producto y la integración vertical. De acuerdo con la teoría de los costes de transacción, la integración vertical está positivamente relacionada con la especificidad y con la incertidumbre. Nuestros resultados también encuentran que el tamaño de la bodega es una variable a considerar en la decisión de fabricar o comprar. Como se esperaba, nuestros resultados sugieren que una mayor integración vertical está asociada con una mayor calidad del producto.

description: Photocatalytic reactions on TiO2 have recently gained an enormous resurgence because of various new strategies and findings that promise to drastically increase efficiency and specificity of such reactions by modifications of the titania scaffold and chemistry. In view of geometry, in particular, anodic TiO2 nanotubes have attracted wide interest, as they allow a high degree of control over the separation of photogenerated charge carriers not only in photocatalytic reactions but also in photoelectrochemical reactions. A key advantage of ordered nanotube arrays is that nanotube modifications can be embedded site specifically into the tube wall; that is, cocatalysts, doping species, or junctions can be placed at highly defined desired locations (or with a desired regular geometry or pattern) along the tube wall. This allows an unprecedented level of engineering of energetics of reaction sites for catalytic and photocatalytic reactions, which target not only higher efficiencies but also the selectivity of reactions. Many recent tube alterations are of a morphologic nature (mesoporous structures, designed faceted crystallites, hybrids, or 1D structures), but a number of color-coded (namely, black, blue, red, green, gray) modifications have attracted wide interest because of the extension of the light absorption spectrum of titania in the visible range and because unique catalytic activity can be induced. The present Perspective gives an overview of TiO2 nanotubes in photocatalysis with an emphasis on the most recent advances in the use of nanotube arrays and discusses the underlying concepts in tailoring their photocatalytic reactivity.

These slices are asymptotically null in the sense that their Lorentz factor relative to stationary observers diverges as $Γ\sim R^{n/2}$. While $1

description: La participación de la mujer en el tejido socioeconómico de las zonas rurales se ha visto frecuentemente infravalorada. Sin embargo, desde hace pocos años existe una clara conciencia por parte de los poderes públicos de que la inclusión de la mujer en las estrategias de dinamización socioeconómica del mundo rural es fundamental para fijar población y generar renta y empleo. El objetivo de este trabajo se centra en determinar la contribución económica de la mujer en el desarrollo del medio rural de la Comunidad Autónoma de Castilla y León. Para ello, se ha analizado la relación existente entre el grado de desarrollo de los municipios rurales y las características socioeconómicas de las mujeres que los habitan. Para alcanzar tal fin, se han empleado tres tipos de técnicas multivariantes: el análisis de componentes principales, la regresión múltiple y el análisis de conglomerados. Los resultados alcanzados permiten afirmar que la participación económica y social de la mujer en el medio rural de Castilla y León se configura como una condición indispensable para alcanzar un mayor bienestar y nivel de desarrollo en esas zonas.

description: Controlling gain and loss of coupled optical cavities can induce non-Hermitian degeneracies of eigenstates, called exceptional points (EPs). Various unconventional phenomena around EPs have been reported, and expected to incorporate extra functionalities into photonic devices. The eigenmode exactly under the EP degeneracy is also predicted to exhibit enhanced radiation. However, such responses have yet to be observed in on-chip lasers, because of both the limited controllability of their gain and loss and the lifting of degeneracy by pump-induced cavity detuning. Here, we report the first non-Hermitian nanophotonic platform based on two electrically pumped photonic crystal lasers and its spontaneous emission at an EP degeneracy. Systematically tuned and independent current injection to our wavelength-scale active heterostructure cavities enables us to demonstrate the clear EP phase transition of their spontaneous emission, accompanied with the spectral coalescence of coupled modes and reversed pump dependence of the intensity. Furthermore, we find experimentally and confirm theoretically the peculiar squared Lorentzian emission spectrum very near the exact EP, which indicates the four-fold enhancement of the photonic local density of states induced purely by the degeneracy. Our results open a new pathway to engineer the light-matter interaction by non-Hermiticity and explore larger reconfigurable laser arrays for further non-Hermitian features and physics.

The cavity light is used to engineer the thermal reservoirs and to steer the resonator through a thermodynamic cycle. In particular, the feedback is used to properly modulate the light fluctuations inside the cavity and hence to realize efficient thermodynamic transformations with realistic optomechanical devices.

description: We present a new measurement of J/psi production in Pb-Pb collisions at 158 GeV/nucleon, from the data sample collected in year 2000 by the NA50 Collaboration, under improved experimental conditions with respect to previous years. With the target system placed in vacuum, the setup was better adapted to study, in particular, the most peripheral nuclear collisions with unprecedented accuracy. The analysis of this data sample shows that the (J/psi)/Drell-Yan cross-sections ratio measured in the most peripheral Pb-Pb interactions is in good agreement with the nuclear absorption pattern extrapolated from the studies of proton-nucleus collisions. Furthermore, this new measurement confirms our previous observation that the (J/psi)/Drell-Yan cross-sections ratio departs from the normal nuclear absorption pattern for semi-central Pb-Pb collisions and that this ratio persistently decreases up to the most central collisions.

A civilizáció terjedése nyomán bolygó fosszilis erőforrásai fogynak, az egyre drágább energiával való takarékoskodás gazdasági és ökológiai kényszer lett. Hazánkban is fokozatosan nőtt az új épületeknél előírt hőszigetelési követelmény, elterjedt beruházás az épületek utólagos hővédelme. A hőszigetelések egyre vastagabbak és hatékonyabbak a homlokzatokon, árkádokon és tetőkön - ugyanakkor e felületszerkezeteket kis teherbíróképesség jellemzi. Az épületek külső oldalaira tervezett homlokzati, tető vagy egyéb burkolatok, valamint berendezések, szerelvények - lámpák, árnyékolók, kamerák, napcellák, klíma kültéri egységek stb. - csak a hőszigetelésen keresztül kapcsolhatók a tartószerkezethez. A rögzítések korábban általában nagy szilárdságú, ezért jó hővezető anyagokból (pl. alumínium, acél, - ritkán - rozsdamentes acél stb.) készültek - ezek hőhidat képeznek, illetve vízszigetelési gondokat is eredményeznek. A hőhidak a létesítmény egész élettartama alatt komolyan rontják a hőszigetelés hatékonyságát, időszakonként helyi páralecsapódást okozhatnak. Bár egyetlen négyzetcentiméter alumínium hőhíd - a fogadószerkezettől függően - akár annyi hőveszteséget okozhat, mint 1 m2 jó minőségű hőszigetelés, a hőhidas rögzítők kedvezőtlen hatását a beépítés helyén nem lehet érzékelni, nem éri el az ingerküszöbünket. A hőszigetelési zónába előre vagy utólag beépített tartóelemek környezetében a megszakított hőszigetelés fel- vagy visszaépítése nem egyenértékű, utóbbi néha teljesen elmarad –  tovább növelve a hőveszteséget.

description: In this paper, we analytically study the critical exponents and universal amplitudes of the thermodynamic curvatures such as the intrinsic and extrinsic curvature at the critical point of the small-large black hole phase transition for the charged AdS black holes. At the critical point, it is found that the normalized intrinsic curvature $R_N$ and extrinsic curvature $K_N$ has critical exponents 2 and 1, respectively. Based on them, the universal amplitudes $R_Nt^2$ and $K_Nt$ are calculated with the temperature parameter $t=T/T_c-1$ where $T_c$ the critical value of the temperature. Near the critical point, we find that the critical amplitude of $R_Nt^2$ and $K_Nt$ is $-\frac{1}{2}$ when $t\rightarrow0^+$, whereas $R_Nt^2\approx -\frac{1}{8}$ and $K_Nt\approx-\frac{1}{4}$ in the limit $t\rightarrow0^-$. These results not only hold for the four dimensional charged AdS black hole, but also for the higher dimensional cases. Therefore, such universal properties will cast new insight into the thermodynamic geometries and black hole phase transitions.

Revisiting the thermal relaxation of neutron stars

description: In this work we revisit the thermal relaxation process for neutron stars. Such process is associated with the thermal coupling between the core and the crust of neutron stars. The thermal relaxation, which takes place at around 10 -- 100 years, is manifested as a sudden drop of the star's surface temperature. Such drop is smooth for slow cooling objects and very sharp for those with fast cooling. In our study we focus particularly on the cooling of neutron stars whose mass is slightly greater than the value above which the direct Urca (DU) process sets in. Considering different mechanisms for neutrino production in each region of the star, and working with equations of state with different properties, we solve the thermal evolution equation and calculate the thermal relaxation time for ample range of neutron star masses. By performing a comprehensive study of neutron stars just above the onset of the direct Urca process we show that stars under these conditions exhibit a peculiar thermal relaxation behavior. We demonstrate that such stars exhibit an abnormally late relaxation time, characterized by a second drop of its surface temperature taking place a later ages. We qualify such behavior by showing that it is associated with limited spatial distribution of the DU process is such stars. We show that as the star's mass increase, the DU region also grows and the start exhibits the expected behavior of fast cooling stars. Finally we show that one can expect high relaxation times for stars in which the DU process takes place in a radius not larger than 3 km.

description: As shown by Overhauser and others, accurate pair densities for the uniform electron gas may be found by solving a two-electron scattering problem with an effective screened electron-electron repulsion. In this work we explore the extension of this approach to nonuniform systems, and we discuss its potential for density functional theory. For the spherically- and system-averaged pair density of two-electron atoms we obtain very accurate short-range properties, including, for nuclear charge $Z\ge 2$, ``on-top'' values (zero electron-electron distance) essentially indistinguishable from those coming from precise variational wavefunctions. By means of a nonlinear adiabatic connection that separates long- and short-range effects, we also obtain Kohn-Sham correlation energies whose error is less than 4 mHartree, again for $Z\ge 2$, and short-range-only correlation energies whose accuracy is one order of magnitude better.

description: La eco-eficiencia se define mediante la ratio “valor económico/impactos ambientales”. En este trabajo se evalúa la eco-eficiencia de la producción de cítricos en la Comunidad Valenciana. Se han construido 24 escenarios de producción de naranjas según sus prácticas agrícolas y se han determinado sus impactos ambientales mediante Análisis de Ciclo de Vida así como su valor económico añadido. Los resultados se refirieron a 1 kg de naranjas. La integración de la evaluación económica y la ambiental en la ratio se realizó mediante Data Envelopment Analysis. Entre los escenarios más eco-eficientes predominaron los de producción ecológica.

description: We investigate the propagation of a piezoelectric surface acoustic wave (SAW) across a GaAs/Al$_X$Ga$_{1-X}$As heterostructure surface, on which there is fixed a metallic split-gate. Our method is based on a finite element formulation of the underlying equations of motion, and is performed in three-dimensions fully incorporating the geometry and material composition of the substrate and gates. We demonstrate attenuation of the SAW amplitude as a result of the presence of both mechanical and electrical gates on the surface. We show that the incorporation of a simple model for the screening by the two-dimensional electron gas (2DEG), results in a total electric potential modulation that suggests a mechanism for the capture and release of electrons by the SAW. Our simulations suggest the absence of any significant turbulence in the SAW motion which could hamper the operation of SAW based quantum devices of a more complex geometry.

Defining and servicing mental health in a remote northern community
Creators: name: Harckham, Rebecca Clare
Publisher: name: University of British Columbia

description: On a visit to the community of Arviat that extended over two months of spring of 2001, interviews were conducted with community members on the subject of mental health. In all, twenty interviews were recorded, documenting perceptions of community members regarding definitions of mental health, identification and discussion of mental health problems, and evaluations of Arviat's mental health services. Great disparity existed among definitions of mental health. This lack of a consistent definition of mental health may be an obstacle faced by those extending or designing related services in remote Arctic communities. The participants of the study provided a long list of problems experienced by their community that they would classify as mental health problems. In their critical analysis of formal mental health services, interviewees noted pressing problems, namely: scarcity, lack of continuity, lack of co-ordination, ineffectiveness, lack of recognition of community context, and cultural inappropriateness. Information offered by participants illuminated a need for further clarification of definitions of community wellness and of mental health problems, inclusion of the community in the development and maintenance of mental health endeavors, and exploration of alternatives or improvements to current systems of mental health services.

description: We estimate how climate variables affect price and acreage of productive farmland using the Ricardian approach. Furthermore, we use our estimations to evaluate the joint effects of possible climate changes within the time horizon of 2010 and 2050. Our results show that the price of rainfed land in Spain tends to increase but rainfed acreage decreases. On the other hand, the effect on irrigated farmland price and acreage presents some mixed results, however, in the long run the dominant pattern is clearly increasing for both prices and acreage.

description: Nonlinear `sigma' models in two dimensions have BPS solitons which are solutions of self- and anti-self-duality constraints. In this paper, we find their analogues for fuzzy sigma models on fuzzy spheres which were treated in detail by us in earlier work. We show that fuzzy BPS solitons are quantized versions of `Bott projectors', and construct them explicitly. Their supersymmetric versions follow from the work of S. Kurkcuoglu.

description: En el año 2007 fue aprobada por el Parlamento de Galicia la ley de creación del Banco de Tierras de Galicia. Entre los objetivos planteados por esta ley figura el mantenimiento de la Superficie Agrícola Utilizada (SAU) de la Comunidad Autónoma y la recuperación de la que se habría perdido en años anteriores. Trabajos previamente publicados por otros autores, apoyados fundamentalmente sobre los datos de los Censos Agrarios, concluyeron que, efectivamente, la SAU habría descendido en Galicia de modo muy considerable durante el último medio siglo. Dado que el estudio de la evolución de los usos del suelo requiere el análisis de diferentes fuentes de información de tipo estadístico y cartográfico, este trabajo tiene como objetivo revisar las conclusiones sobre la evolución de SAU tratando de integrar la información ofrecida por otras fuentes (anuarios estadísticos, mapas de usos, SIGPAC, entre otros). Las conclusiones del trabajo no ponen en duda la existencia de un descenso de SAU, pero sitúan el período de mayor descenso en las décadas posteriores a 1990 y ofrecen una estimación de la superficie afectada en torno a las 75.000 ha.

description: Optomechanical systems are suitable for elucidating quantum phenomena at the macroscopic scale in the sense of the mass scale. The systems should be well-isolated from the environment to avoid classical noises, which conceal quantum signals. Optical levitation is a promising way to isolate optomechanical systems from the environment. To realize optical levitation, all degrees of freedom need to be trapped. Until now, longitudinal trapping and rotational trapping of a mirror with optical radiation pressure have been studied in detail and validated with various experiments. However, less attention has been paid to the transversal trapping of a mirror. Herein, we report a pioneering result where we experimentally confirmed transversal trapping of a mirror of a Fabry-Pérot cavity using a torsional pendulum. Through this demonstration, we experimentally proved that optical levitation is realizable with only two Fabry-Pérot cavities that are aligned vertically. This work paves the way toward optical levitation and realizing a macroscopic quantum system.

description: Jordan acceded to the WTO in 1999. In its accession Jordan agreed, for example, to reduce tariffs on imported products and open its services market; it also modified its intellectual property regime. Jordan enjoyed special and differential treatment in few areas and was not able to designate olive oil as a good eligible for special safeguards. The WTO agreements required fundamental changes in the domestic laws and regulations of Jordan. The article concludes by arguing that Jordan's accession to the WTO was a lengthy and costly process. Jordan agreed to an arduous package of legal and economic reforms. Given that Jordan agreed to greater commitments compared to the obligations of the original WTO members, the multilateral trading system witnessed an accession saga.
PECULIARITIES OF INTERNATIONAL WORDS TRANSLATION

description: The article discusses foreign words and peculiarities in translating them. In the modern world, the majority of linguists observe an astounding increase in the evolution of many language kinds. Every word, even those that sprang on their own, has a backstory. The most brilliant aspect of language is its vocabulary, which has connections to every aspect of human civilization, including politics, sports, technology, science, and the arts. This is because words are generated in these domains to facilitate communication, which is essential to human activity. Knowledge of their origins is a valuable resource for the development of technical terminology. Greatest number of English words, including foreign words, are ambiguous and have several meanings. This is especially true with technical terms, where words can have multiple meanings depending on the context. International words that are the consequence of linguistic borrowing make up the research's material.

description: Model quantization is a widely used technique to compress and accelerate deep neural network (DNN) inference. Emergent DNN hardware accelerators begin to support mixed precision (1-8 bits) to further improve the computation efficiency, which raises a great challenge to find the optimal bitwidth for each layer: it requires domain experts to explore the vast design space trading off among accuracy, latency, energy, and model size, which is both time-consuming and sub-optimal. Conventional quantization algorithm ignores the different hardware architectures and quantizes all the layers in a uniform way. In this paper, we introduce the Hardware-Aware Automated Quantization (HAQ) framework which leverages the reinforcement learning to automatically determine the quantization policy, and we take the hardware accelerator's feedback in the design loop. Rather than relying on proxy signals such as FLOPs and model size, we employ a hardware simulator to generate direct feedback signals (latency and energy) to the RL agent. Compared with conventional methods, our framework is fully automated and can specialize the quantization policy for different neural network architectures and hardware architectures. Our framework effectively reduced the latency by 1.4-1.95x and the energy consumption by 1.9x with negligible loss of accuracy compared with the fixed bitwidth (8 bits) quantization. Our framework reveals that the optimal policies on different hardware architectures (i.e., edge and cloud architectures) under different resource constraints (i.e., latency, energy, and model size) are drastically different. We interpreted the implication of different quantization policies, which offer insights for both neural network architecture design and hardware architecture design.
