description: ZrSiS, an intriguing candidate of topological nodal line semimetals, was discovered to have exotic surface floating two-dimensional (2D) electrons [Phys. Rev. X 7, 041073 (2017)], which are likely to interact with surface phonons. Here, we reveal a prominent Kohn anomaly in a surface phonon branch by mapping out the surface phonon dispersions of ZrSiS using high-resolution electron energy loss spectroscopy. Theoretical analysis via an electron-phonon coupling (EPC) model attributes the strong renormalization of the surface phonon branch to the interactions with the surface floating 2D electrons. With the random phase approximation, we calculate the phonon self-energy and evaluate the mode-specific EPC constant by fitting the experimental data. The EPC picture provided here may be important for potential applications of topological nodal line semimetals.

description: Pyrrole-based adsorbents were developed electrochemically using systems: (i) pyrrole-potassium bromide, (ii) pyrrole-KBr-an anionic surfactant sodium dodecyl sulfate, and (iii) pyrrole-KBr-NaDS-Prussian blue. Growth kinetics and morphological studies were carried out at different experimental conditions. The study revealed the formation of nanosized particles, suitable for the removal of methylene blue as evident by high adsorption capacity = 447.7 mg g−1. The effect of adsorption dosage, contact time, pH, and temperature on methylene blue removal has been studied. The data followed pseudo-second-order kinetic, Freundlich isotherm model and found to be endothermic and spontaneous in nature.

description: Orange-fleshed sweetpotato (OFSP) varieties rich in beta-carotene, a precursor of vitamin A are one of the least expensive sources of dietary vitamin A in Sub-Saharan Africa, where most sweetpotato is consumed as boiled or steamed roots. One major question is how its use can be expanded among urban African consumers. In many urban centers, access to fresh roots is principally at the wet-markets, thus precluding many high-end urban consumers. One solution is to develop products incorporating OFSP into products typically consumed by middle-class consumers (such as bakery products) that can supply significant amounts of vitamin A. Viable products must have production costs equal to or lower than the equivalent product without OFSP and consumers must like their taste compared to regular products. Sweetpotato can replace upto 50% of wheat-flour in bakery products, depending on product and local tastes. In Rwanda, we produced four products in collaboration with a commercial bakery, using different combinations of ingredients: wheat-flour only; mixture of wheat-flour and OFSP-flour; and mixture of wheat-flour and OFSP-puree. Sensory consumer tests and analysis of data using means, t-tests, and ordered-logit, showed that bread made out of a mix of 30% OFSP-puree and 70% wheat-flour was preferred to that made of 100% wheat-flour. Consumers showed no preference between doughnuts and queen cakes made from 100% wheat-flour and those with mix of 60% wheat-flour and 40% OFSP-puree. Biscuits made of 40% OFSP-puree and 60% wheat-flour were preferred to those made with 100% wheat-flour. Therefore, the OFSP-based products were acceptable to Rwandan consumers.

description: Using data from ICRISAT 2010/11 household and fertilizer retailer surveys, the study reveals that open vouchers enhance farmers input choice. The targeting of vulnerable farmers was efficient in selecting, households with less livestock ownership and those affected by HIV/AIDS. The use of open vouchers enabled retailers to sale agricultural inputs, boost revenue and link them to suppliers. The use of open voucher is preferable in areas where retailer’s infrastructure and mobile telephone network coverage is good. Timely payment of retailers and suppliers is necessary to encourage their willingness to participate in the program. Risk bearing options like wholesaler insurance are critical to ensure wholesalers are compensated in the event that agro-inputs are not purchased. Credit facilities specifically meant for retailers to stock and trade agricultural inputs will be useful. Programs and policies that enable farmers to access credit to buy inputs should also be put in place. A well planned voucher system links commercial retail channels and has multiplier effects to the society. Experiences from the PRP input program demonstrated that voucher system, as an alternative to direct input distribution, is workable in the Zimbabwe situation and can be adequately supported by suppliers and rural retailers. Voucher programs have the potential to support retail linkage and there is need for increasing more stakeholders, such as seed and fertilizer companies, and wholesalers.

description: Transition metal dichalcogenide (TMD) monolayers and heterostructures have emerged as a compelling class of materials with transformative new science that may be harnessed for novel device technologies. These materials are commonly fabricated by exfoliation of flakes from bulk crystals, but wafer-scale epitaxy of single crystal films is required to advance the field. This article reviews the fundamental aspects of epitaxial growth of van der Waals bonded crystals specific to TMD films. The structural and electronic properties of TMD crystals are initially described along with sources and methods used for vapor phase deposition. Issues specific to TMD epitaxy are critically reviewed including substrate properties and film-substrate orientation and bonding. The current status of TMD epitaxy on different substrate types is discussed along with characterization techniques for large area epitaxial films. Future directions are proposed including developments in substrates, in situ and full wafer characterization techniques and heterostructure growth.

description: The stellar magnetic field completely dominates the environment around late-type stars. It is responsible for driving the coronal high-energy radiation (e.g. EUV/X-rays), the development of stellar winds, and the generation transient events such as flares and coronal mass ejections (CMEs). While progress has been made for the first two processes, our understanding of the eruptive behavior in late-type stars is still very limited. One example of this is the fact that despite the frequent and highly energetic flaring observed in active stars, direct evidence for stellar CMEs is almost non-existent. Here we discuss realistic 3D simulations of stellar CMEs, analyzing their resulting properties in contrast with solar eruptions, and use them to provide a common framework to interpret the available stellar observations. Additionally, we present results from the first 3D CME simulations in M-dwarf stars, with emphasis on possible observable signatures imprinted in the stellar corona.

description: For the five overseas countries considered in this study (Germany, France, Italy, the United Kingdom and Japan), data on real GDP are released on a quarterly basis at least two months after the end-of-quarter. Other indicators of economic activity are published sooner than real GDP data, however. The purpose of this study is to present some simple models to forecast the quarter-over-quarter growth of real GDP for the current quarter (or the quarter just completed for which figures have not yet been released) in each of the overseas economies noted above. These models rely primarily on the information provided by monthly indicators of economic activity selected on the basis of their ability to predict changes in real GDP in the late 1980s and early 1990s.
description: Les données du PIB réel dans les cinq pays d’outre-mer considérés dans la présente étude, soit l’Allemagne, la France, l’Italie, le Royaume-Uni et le Japon, sont publiées sur une base trimestrielle et après un délai d’au moins deux mois. Certains autres indicateurs de l’activité économique sont publiés plus fréquemment et plus rapidement que le PIB réel. Nous présentons ici, pour chacun des pays d’outre-mer, des modèles de prévision du taux de croissance d’un trimestre à l’autre du PIB réel du trimestre en cours (ou terminé, mais dont les données n’ont pas encore été publiées) qui sont d’une grande simplicité et qui utilisent, notamment, l’information véhiculée par des indicateurs mensuels de l’activité économique. Une caractéristique essentielle de ces modèles est qu’ils reposent sur des indicateurs sélectionnés sur la base de leur capacité de prévoir l’évolution du PIB réel à la fin des années 80 et au début des années 90.

description: This report examines the ways that fuel prices are transmitted to wholesale produce prices via transportation costs. Specifically, it focuses on marketing costs for asparagus,cantaloupes, table grapes, oranges, bell peppers, and tomatoes. Results of the study indicate that transportation costs significantly increase the costs of marketing these produce items and therefore their wholesale price. The impact of fuel prices on produce prices depends on a number of factors, including the distance between wholesale markets and the source of the produce, the method of transportation, the importance and timing of imports, and commodity-specific factors such as perishability. Overall, as fuel prices rise, so do wholesale produce prices and the margins between farm and wholesale prices.

description: In the past decade superconducting nanowire single photon detectors (SNSPDs) have gradually become an indispensable part of any demanding quantum optics experiment. Until now, most SNSPDs are coupled to single-mode fibers. SNSPDs coupled to multimode fibers have shown promising efficiencies but are yet to achieve high time resolution. For a number of applications ranging from quantum nano-photonics to bio-optics, high efficiency and high time-resolution are desired at the same time. In this paper, we demonstrate the role of polarization on the efficiency of multi-mode fiber coupled detectors, and show how it can be addressed. We fabricated high performance 20, 25 and 50μm diameter detectors targeted for visible, near infrared, and telecom wavelengths. A custom-built setup was used to simulate realistic experiments with randomized modes in the fiber. We simultaneously achieved system efficiency >80% and time resolution <20 ps and made large detectors that offer outstanding performances.

description: In the context of the connection among galaxy-galaxy interaction, starbursts and nuclear activity, we present and discuss a quantitative morphological analysis based on BVR images and a detailed spectroscopic investigation of two interacting galaxies, the Seyfert 2 Tol1238-364 (IC 3639) and its companion ESO381-G009, forming a triple system with ESO381-G006. Broad-band optical photometry is complemented by Halpha imaging, which provides information about the distribution of star forming regions across the galaxies. Long-slit spectroscopic data obtained at different position angles of the slit are employed to determine the physical conditions of circumnuclear and extranuclear regions. A mixture of thermal and non-thermal ionizing radiation is found in the surroundings of the nucleus of Tol1238-364 and the energy budget supports the presence of a circumnuclear starburst.Several regions in both the galaxies show anomalous line ratios: additional ionization by shock-heating and low ionization of some extranuclear HII regions are suggested as possible explanations. An analysis of the emission-line profiles reveals the presence of a broad Halpha component in the nuclear region of Tol1238-364. Independent estimates of the star formation rates (SFR) were obtained through flux-calibrated Halpha-images and FIR emission in the four IRAS bands. Overall SFR densities have been compared with the SFR densities derived from Halpha emission in the individual regions of the galaxies sampled by long-slit spectra. In both galaxies an enhancement of the star formation activity with respect to isolated galaxies is revealed. The prevalence of starburst or nuclear activity has been examined through FIR color indices. The interaction scenario is discussed on the basis of the observed galaxy properties.

description: Despite its enormous potential, Myanmar’s agriculture has underperformed over the past fifty years. Today, per capita earnings in agriculture average roughly $200 a year, one-half to one-third of the levels achieved by its regional peers. Given that two-thirds of the population works primarily in agriculture, low farm productivity translates into high rates of poverty and food insecurity. Currently, about one quarter of the population falls below the national poverty line. As a result, in spite of national rice self-sufficiency, food security for many households and individuals remains elusive. Poor households spend over 70% of their income on food. In addition, fully one-third of rural households borrow at some point during the year in order to purchase food. Even after shouldering this heavy financial burden, up to one-half of rural households report having to navigate two months each year without adequate food supplies, leaving one-third of the country’s children stunted.

description: The electronic properties of quarter-filled organic materials showing spin-Peierls transition are investigated theoretically. By studying the one-dimensional extended Peierls-Hubbard model analytically as well as numerically, we find that there is a competition between two different spin-Peierls states due to the tetramized lattice distortion in the strongly correlated regime. One is accompanied by lattice dimerization which can be interpreted as a spontaneous Mott insulator, while the other shows the existence of charge order of Wigner crystal-type. Results of numerical density matrix renormalization group computations on sufficiently large system sizes show that the latter is stabilized in the ground state when both the on-site and the inter-site Coulomb interactions are large.

$B\to ϕK_s$ versus Electric Dipole Moment of $^{199}$Hg Atom in Supersymmetric Models with Right-handed Squark Mixing

description: The correlation between the CP asymmetry in $B\to ϕK_s$ ($S_{ϕK_s}$) and the chromoelectric dipole moment (CEDM) of strange quark ($d_s^C$), which is constrained by the electric dipole moment (EDM) of $^{199}$Hg, is studied in the supersymmetric (SUSY) models with the right-handed squark mixing. It is known that, if the right-handed bottom and strange squarks have a CP-violating mixing, such as in the SUSY SU(5) GUT with right-handed neutrinos, the induced gluon-penguin diagram may give a sizable contribution to $S_{ϕK_s}$. However, when the left-handed bottom and strange squarks also have a mixing, the conspiracy of the left and right-handed squarks may lead to a sizable $d_s^C$, which is enhanced by $m_b/m_s$. While the estimate for the EDM of $^{199}$Hg, induced by $d^C_s$, might have large uncertainties due to the hadron and nuclear dynamics, the current bound implies the gluon penguin contribution by the right-handed squarks to $S_{ϕK_s}$ should be suppressed and the deviation of $S_{ϕK_s}$ from the Standard Model may not be so large. Also, we discuss the constraint from the EDM of $^{199}$Hg in the SUSY SU(5) GUT with the right-handed neutrinos.

description: The magnetic proximity effect in top and bottom Pt layers induced by Co in Ta/Pt/Co/Pt multilayers has been studied by interface sensitive, element specific x-ray resonant magnetic reflectivity. The asymmetry ratio for circularly polarized x-rays of left and right helicity has been measured at the Pt $L_3$ absorption edge (11567 eV) with an in-plane magnetic field ($\pm158$ mT) to verify its magnetic origin. The proximity-induced magnetic moment in the bottom Pt layer decreases with the thickness of the Ta buffer layer. Grazing incidence x-ray diffraction has been carried out to show that the Ta buffer layer induces the growth of Pt(011) rather than Pt(111) which in turn reduces the induced moment. A detailed density functional theory study shows that an adjacent Co layer induces more magnetic moment in Pt(111) than in Pt(011). The manipulation of the magnetism in Pt by the insertion of a Ta buffer layer provides a new way of controlling the magnetic proximity effect which is of huge importance in spin-transport experiments across similar kind of interfaces.

description: This study uses data from qualitative research and different national representative surveys to identify factors limiting smallholder linkages to the growing markets for soybean in Zambia and to provide concrete strategies to overcome them. Soybean production remains low despite its clear benefits for smallholders. This is due to limited availability of high yielding soybean seed and limited incentive for private investment in smallholder soybean seed multiplication. Low production is also related to agronomic practices, such as late planting and poor disease management as well as low usage of yield improving inputs such as inoculum.

description: Vital signs, such as heart rate (HR), heart rate variability (HRV), respiratory rate (RR), are important indicators for a person's health. Vital signs are traditionally measured with contact sensors, and may be inconvenient and cause discomfort during continuous monitoring. Commercial cameras are promising contact-free sensors, and remote photoplethysmography (rPPG) have been studied to remotely monitor heart rate from face videos. For remote RR measurement, most prior art was based on small periodical motions of chest regions caused by breathing cycles, which are vulnerable to subjects' voluntary movements. This paper explores remote RR measurement based on rPPG obtained from face videos. The paper employs motion compensation, two-phase temporal filtering, and signal pruning to capture signals with high quality. The experimental results demonstrate that the proposed framework can obtain accurate RR results and can provide HR, HRV and RR measurement synergistically in one framework.

description: Social critics have taken aim at modern production agriculture using a common theme: many food, health, and environmental problems are explained by corporate farms, agribusinesses, and fast-food restaurants failing to account for the full costs of their actions. How accurate is this diagnosis? How feasible is the assumption that these externalities are most effectively mitigated via Pigovian taxes and subsidies? Drawing on my experiences at a National Institute of Medicine meeting on the subject, I seek to clarify the definition and nature of externalities and discuss situations in which public policy is most and least effective in efficiently making "hidden” costs of food visible.

description: This paper examines whether the hypothesis of economic convergence holds for the Canadian provinces. Using data on real gross domestic product per capita and on factor productivity from 1966 to 1992, the paper shows, using two different methods, that the convergence hypothesis cannot be rejected. This evidence supports the findings of other authors who have studied convergence among Canadian provinces.

description: We present indications, based on a sample of 303 Abell clusters, for a relation between the dynamical state of clusters and the alignments of galaxy members with their parent cluster major axis orientation as well as with the large scale environment within which the clusters are embedded. The statistical results are complemented with a deep, wide-field case study of galaxy alignments in the cluster A521, which is characterised by multiple merging events (Maurogrdato et al 2000, Ferrari et al. 2003) and whose galaxy members show a strong alignment signal out to $\sim 5 h^{-1}$ Mpc. Our results show that galaxy alignments appear to be stronger the more dynamically young is the cluster, especially when found in high-density environments. This relation complements the recently found {``Cluster Substructure - Alignment Connection''} (Plionis & Basilakos 2002) by which dynamically young clusters, found in high-density environments, show stronger cluster-cluster alignments.

title: The Causes of Unemployment in Canada: A Review of the Evidence
Creators: name: Poloz, Stephen S.
Publisher: name: Bank of Canada
Year: 1994

description: This paper reviews various competing theories of structural unemployment and considers whether they may be used to explain any of the rise in unemployment experienced by Canada during the most recent economic cycle. The central message that emerges is that one should take into account multiple possible structural explanations when forming judgments about the non-accelerating-inflation rate of unemployment (the NAIRU). Furthermore, the degree of uncertainty associated with existing empirical work suggests that one should allow for a range of NAIRU estimates in reaching an understanding of economic developments. A balanced assessment of the available methodologies suggests that the NAIRU has risen somewhat during the 1990s, mainly because of a steep rise in the rate of payroll taxation. Nevertheless, the paper concludes that this rise in the NAIRU is likely to be temporary, both because the payroll tax effect ought to be digestible over time and because some reforms to the unemployment insurance system have already been implemented.
description: L'auteur examine différentes théories du chômage structurel et la possibilité de s'en inspirer pour tenter d'expliquer les hausses du chômage que le Canada a connues au cours du dernier cycle économique. La principale conclusion de cette étude est qu'il faut tenir compte de plusieurs hypothèses de nature structurelle lorsqu'on forme des jugements au sujet du taux de chômage non accélérationniste (TCNA). En outre, les résultats des estimations effectuées jusqu'ici sur cette variable étant incertains, il y aurait peut-être lieu de prendre en compte un éventail d'estimations du TCNA afin d'en arriver à une certaine compréhension de l'évolution de l'économie. Un examen équilibré des diverses méthodologies indique que le TCNA s'est accru un peu au cours des années 90, en raison principalement de la forte augmentation du taux des charges sociales. Néanmoins, l'auteur en vient à la conclusion que cette hausse du TCNA ne devrait être que temporaire, d'une part, parce que l'effet des charges sociales devrait finir par être absorbé au fil du temps et, d'autre part, parce que certaines réformes de l'assurance-chômage ont déjà commencé à entrer en vigueur.

title: Searching for the Liquidity Effect in Canada
Creators: name: Fung, Ben

Publisher: name: Bank of Canada

description: This paper examines the empirical evidence of the liquidity effect in Canada. In the presence of the liquidity effect, the initial impact of an unanticipated expansionary monetary policy is to lower nominal and real interest rates for a short period of time. Eventually, however, the anticipated inflation effect will come into force and dominate the liquidity effect as people adjust their inflation expectations to the new money growth rate. As a result, interest rates will then increase. In this paper, we use vector autoregression (VAR) methods to study how interest rates, output and exchange rates respond to shocks to monetary policy. We use the excess cash reserves of the chartered banks and the surprise component of excess cash reserves as measures of monetary policy shocks. Shocks to monetary policy are measured by the orthogonalized innovations to these liquidity variables. We find that expansionary shocks to monetary policy are followed by declines in the interest rate, increases in output, and depreciations of the Canadian dollar. The results are robust to different orderings of the variables used in the VAR estimation. The response of the interest rate to monetary policy shocks is robust to different measures of liquidity, but the responses of other variables vary slightly.
description: Les auteurs examinent empiriquement la pertinence des effets de liquidité au Canada. Sous l'hypothèse d'effet de liquidité, l'incidence initiale d'un choc expansionniste non anticipé de la politique monétaire consiste en une diminution momentanée des taux d'intérêt nominaux et réels. Cependant, comme les anticipations d'inflation s'ajustent au nouveau taux d'expansion monétaire, leur effet finit par se manifester et dominer l'effet de liquidité. Les taux d'intérêt se mettent alors à augmenter. Dans leur étude, les auteurs font appel à la méthode d'estimation des vecteurs autorégressifs pour étudier comment les taux d'intérêt, la production et les taux de change réagissent aux chocs de politique monétaire. Ils se servent des réserves excédentaires des banques à charte et de leur composante non anticipée comme mesures des chocs de la politique monétaire. Plus précisément, ceux-ci sont mesurés par les innovations orthogonalisées de ces variables de liquidité. Les auteurs ont observé que les chocs expansionnistes de politique monétaire sont suivis par des baisses de taux d'intérêt, des hausses de la production et des dépréciations du dollar canadien. Les résultats obtenus résistent bien aux changements d'agencement des variables utilisées dans l'estimation des vecteurs autoregressifs. La réaction des taux d'intérêt aux chocs de politique monétaire est peu sensible aux diverses mesures de liquidité utilisées, mais la réaction des autres variables a tendance à varier légèrement.

description: We have measured Ce 4f spectral weights of extremely $α$-like Ce-transition metal intermetallic compounds CeRh$_x$ (x=2,3) and CeNi$_x$ (x=2,5) by using the {\it bulk-sensitive} resonant photoemission technique at the Ce $M_5$($3d_{5/2}\to4f$)-edge. Unprecedentedly high energy resolution and longer escape depth of photoemitted electron at this photon energy enabled us to distinguish the sharp Kondo resonance tails at the Fermi level, which can be well described by the Gunnarsson-Schönhammer(GS) calculation based on the Anderson Impurity Hamiltonian. On the other hand, the itinerant 4f band description shows big discrepancies, which implies that Ce 4f electrons retain localized characters even in extremely $α$-like compounds.

description: The polarized optical reflectance spectra of the quasi two dimensional organic correlated electron system $κ$-(BEDT-TTF)$_{2}$Cu[N(CN)$_{2}$]$Y$, $Y =$ Br and Cl are measured in the infrared region. The former shows the superconductivity at $T_{\rm c} \simeq$ 11.6 K and the latter does the antiferromagnetic insulator transition at $T_{\rm N} \simeq$ 28 K. Both the specific molecular vibration mode $ν_{3}(a_{g})$ of the BEDT-TTF molecule and the optical conductivity hump in the mid-infrared region change correlatively at $T^{*} \simeq$ 38 K of $κ$-(BEDT-TTF)$_{2}$Cu[N(CN)$_{2}$]Br, although no indication of $T^{*}$ but the insulating behaviour below $T_{\rm ins} \simeq$ 50-60 K are found in $κ$-(BEDT-TTF)$_{2}$Cu[N(CN)$_{2}$]Cl. The results suggest that the electron-molecular vibration coupling on the $ν_{3}(a_{g})$ mode becomes weak due to the enhancement of the itinerant nature of the carriers on the dimer of the BEDT-TTF molecules below $T^{*}$, while it does strong below $T_{\rm ins}$ because of the localized carriers on the dimer. These changes are in agreement with the reduction and the enhancement of the mid-infrared conductivity hump below $T^{*}$ and $T_{\rm ins}$, respectively, which originates from the transitions between the upper and lower Mott-Hubbard bands. The present observations demonstrate that two different metallic states of $κ$-(BEDT-TTF)$_{2}$Cu[N(CN)$_{2}$]Br are regarded as {\it a correlated good metal} below $T^{*}$ including the superconducting state and {\it a half filling bad metal} above $T^{*}$. In contrast the insulating state of $κ$-(BEDT-TTF)$_{2}$Cu[N(CN)$_{2}$]Cl below $T_{\rm ins}$ is the Mott insulator.

description: In this paper, we study the adversarial robustness of subspace learning problems. Different from the assumptions made in existing work on robust subspace learning where data samples are contaminated by gross sparse outliers or small dense noises, we consider a more powerful adversary who can first observe the data matrix and then intentionally modify the whole data matrix. We first characterize the optimal rank-one attack strategy that maximizes the subspace distance between the subspace learned from the original data matrix and that learned from the modified data matrix. We then generalize the study to the scenario without the rank constraint and characterize the corresponding optimal attack strategy. Our analysis shows that the optimal strategies depend on the singular values of the original data matrix and the adversary's energy budget. Finally, we provide numerical experiments and practical applications to demonstrate the efficiency of the attack strategies.

description: We use a high resolution collisionless simulation of a Virgo--like cluster in a $Λ$CDM cosmology to determine the velocity and clustering properties of the diffuse stellar component in the intracluster region at the present epoch. The simulated cluster builds up hierarchically and tidal interactions between member galaxies and the cluster potential produce a diffuse stellar component free-flying in the intracluster medium. Here we adopt an empirical scheme to identify tracers of the stellar component in the simulation and hence study its properties. We find that at $z=0$ the intracluster stellar light is mostly unrelaxed in velocity space and clustered in structures whose typical clustering radii are about 50 kpc at R=400--500 kpc from the cluster center, and predict the radial velocity distribution expected in spectroscopic follow-up surveys. Finally, we compare the spatial clustering in the simulation with the properties of the Virgo intracluster stellar population, as traced by ongoing intracluster planetary nebulae surveys in Virgo. The preliminary results indicate a substantial agreement with the observed clustering properties of the diffuse stellar population in Virgo.
