description: This study investigated the asymmetric effect of positive and negative monetary policy shocks on output and prices in Nigeria using interest rate shocks. This was with the view to ascertaining the impact of monetary policy on sustainable output growth and price stability in Nigeria from 1986 to 2016. Quarterly secondary data from 1986: Q1 to 2016:Q4 on output (GDP), interest rate, money supply, inflation rate, investment and real effective exchange rate were sourced from Central Bank of Nigeria (CBN) Statistical Bulletin, 2016 and World Development Indicator (WDI), 2018. Data collected were analyzed using Non-linear Autoregressive Distributive Lag (NARDL) econometric techniques. The results showed that in the short run, negative shocks have more significant effects (2.7%) on output than positive shocks (1.2%) but the effects of positive and negative monetary policy shocks do not have significant effects on price level; while in the long run, positive shocks have more significant effects than the negative shocks on both output (3.1% and 1.9%) and prices (-51.1%and 45.1%). The study concluded that monetary policy shocks have asymmetric effects on output and prices in Nigeria both in the short and long run period.

description: The study examines factors that influence the adoption of improved post-harvest storage technologies (IPHSTs) by smallholder maize farmers in Tanzania. The study employed a sample of 1620 observations from the National Panel Survey (NPS). Descriptive statistics indicated that 9 percent of the farmers experienced PHL and an average of 115 kilograms of maize per household is lost in various stages of post-harvest chain. Only 19 percent of farmers adopted IPHSTs. Logit regression results indicated that gender, age, harvest working days, use of hired labour and use of storage protectorant (pesticides and insecticides) had positive and significant influence on PHL. Further, quantity of maize harvested and age of households’ heads had positive and significant influence on adoption of IPHSTs. Therefore, the Government and development agencies should emphasize and promote the adoption of IPHSTs by smallholder farmers in order to mitigate PHL. Provision and support of extension education to farmers through trainings and seminars and extension visits on proper crop post-harvest management, storage technologies and skills is pertinent.
Improving walking symmetry in people with stroke : a pilot study

description: There are over 300,000 Canadians living with the effects of stroke. A stroke damages one side of the brain, resulting in motor impairments to the other half of the body. This leads to asymmetrical walking; the weaker leg is used less in propelling and supporting the body compared to the stronger leg. Improving symmetry is important because asymmetrical walking leads to impaired balance, decreased bone strength, and increased falls. However, little research has looked at improving walking symmetry. This study tests whether applying resistance against the stronger leg can improve walking symmetry in people with stroke. To increase the use of the weaker leg, we make the stronger leg harder to use. Six participants were fitted into the Lokomat, a gait therapy device with a treadmill, harness, and leg-cuffs. The Lokomat was programmed to apply resistance, equivalent to 10% of the hip and knee flexors' maximal voluntary contraction, against the stronger leg. Force-sensitive resistors and motion capture cameras were used to respectively measure single-support stance time and stride length, in order to determine the use of each leg during walking. Subjects walked consecutively for 50 strides with no resistance, 50 strides with resistance against the stronger leg, and 50 strides with resistance removed. We found that applying resistance against the stronger leg can improve walking symmetry and increase the use of the weaker leg to propel and support the body during walking. The study demonstrated the feasibility of this intervention and uncovered aspects of the design to be improved upon.

description: The study examines the profitability and resource use efficiency analysis of poultry feed mills of Bangladesh covering Dhaka, Gazipur, Narsingdi, Kishoreganj and Mymensingh districts. Thirty feed mills which categorized as; high, medium and low quality on the basis of feed conversion ratio (FCR), were purposively selected. The primary and secondary data were collected and analyse on Cobb-Douglas model. Four out of six variables included in the model were explainied significantly. The feed production cost was estimated Tk. 39295, Tk. 38643 and Tk. 37218 per metric tonne (MT) respectively. The cost of high quality feed was more than medium and low quality feed and the gross return was Tk. 43160, Tk. 42330 and Tk. 40500 per MT respectively. It indicates that high quality feed production was more profitable than the medium and low feed production. The results of Cobb-Douglas model indicated that if the supply of quality of raw materials increased, their efficiency would increase for low and medium. It was also found that the ratio of MVP and MFC were less than one which indicated that the resources were over utilized for high quality feed mills and three input out of six underutilized for medium and low quality feeds.

description: Through magneto-transport measurements and analysis of the observed Shubnikov de Haas oscillations in (010) (AlxGa1-x)2O3/Ga2O3 heterostructures, spin-splitting of the Landau levels in the (010) Ga2O3 two-dimensional electron gas (2DEG) has been studied. Analysis indicates that the spin-splitting results from the Zeeman effect. By fitting the both the first and second harmonic of the oscillations as a function of magnetic field, we determine the magnitude of the Zeeman splitting to be 0.4$\hbarω_c$, with a corresponding effective g-factor of 2.7, for magnetic field perpendicular to the 2DEG.

description: The study explores the possibilities of revitalizing existing urban communities, increasing transit ridership, decreasing jobs-housing imbalance, and mitigating the impacts of sprawl from transit corridor development or TCD, a variant of the more general class of TOD or transit-oriented development. We present findings of a study that focuses on the relationship between transit ridership and density and mixed land use developments along major arterial corridors in Los Angeles. Our research focuses on Ventura Boulevard and Vermont Avenue as a comparative study of two heavily subscribed transit corridors. Our analysis suggests that the predominant land use around these corridors is low-density automobile-oriented development which remains transit –unfriendly. However, the City’s policy environment has undergone favorable changes with the introduction new zoning ordinances. In light of these changes, we develop and recommend spatial and urban design strategies that productively utilize surplus and marginal space along transit corridors to accommodate future population growth. It is our expectation that the densification of the underutilized commercial corridors will create vibrant local economies, increase opportunities for market and affordable housing, revitalize retail, and lead to a fuller use of transit lines and increased ridership, a trend that we have already observed in higher density bus station areas

description: Within the mode-coupling theory for the evolution of structural relaxation in glass-forming systems, it is shown that the correlation functions for density fluctuations for states at A_3- and A_4-glass-transition singularities can be presented as an asymptotic series in increasing inverse powers of the logarithm of the time t: $ϕ(t)-f\propto \sum_i g_i(x)$, where $g_n(x)=p_n(\ln x)/x^n$ with p_n denoting some polynomial and x=ln (t/t_0). The results are demonstrated for schematic models describing the system by solely one or two correlators and also for a colloid model with a square-well-interaction potential.

Eight distinct inequalities can thus be ordered according to their tightness to angular momentum.

description: Superconductivity in the presence of a step magnetic field has been recently the focus of many works. This contribution examines the behavior of a two-dimensional superconducting domain, when superconductivity is lost in the whole domain except near the intersection points of the discontinuity edge and the boundary. The problem involves its own effective energy. We provide local estimates of the minimizers in neighbourhoods of the intersection points. Consequently, we introduce new critical fields marking the loss of superconductivity in the vicinity of these points. The study is modelled by the Ginzburg--Landau theory, and large Ginzburg--Landau parameters are considered.

description: Molecular dynamics simulations are used to study the behavior of closely-fitting spherical and ellipsoidal particles moving through a fluid-filled cylinder at nanometer scales. The particle, the cylinder wall and the fluid solvent are all treated as atomic systems, and special attention is given to the effects of varying the wetting properties of the fluid. Although the modification of the solid-fluid interaction leads to significant changes in the microstructure of the fluid, its transport properties are found to be the same as in bulk. Independently of the shape and relative size of the particle, we find two distinct regimes as a function of the degree of wetting, with a sharp transition between them. In the case of a highly-wetting suspending fluid, the particle moves through the cylinder with an average axial velocity in agreement with that obtained from the solution of the continuum Stokes equations. In contrast, in the case of less-wetting fluids, only the early-time motion of the particle is consistent with continuum dynamics. At later times, the particle is eventually adsorbed onto the wall and subsequently executes an intermittent stick-slip motion.We show that van der Walls forces are the dominant contribution to the particle adsorption phenomenon and that depletion forces are weak enough to allow, in the highly-wetting situation, an initially adsorbed particle to spontaneously desorb.

description: With rapid urbanization, millions of people from rural areas have migrated to major cities for employment, leaving their young children at home or bringing their children to urban areas. Whether this labor migration creates substantial mental, physical and educational challenges for these left-behind and migrant children should be considered. This paper uses data from a 9824 students sample from a survey conducted by the authors in Beijing, Suzhou, Anhui and Henan. This study establishes OLS models for identifying the correlation of non-left-behind children, left-behind children and migrant children on health, cognitive and non-cognitive performance. Our empirical findings reveal that the migration of adult household members negatively affects the health status, cognitive and non-cognitive performances of left-behind children and only cognitive performance for migrant children. The effects are particularly prominent for rural children, when the mother migrates out of province.

description: For the last 40 years, international organizations have invested into early warning systems (EWSs) for food crises. Despite today s era of digitalization and big data, current EWSs fall short of informing at-risk populations about food crises. To understand how the dimensions of vulnerability and hazard determine food security risk, we first develop a framework of an optimal EWS based on UNISDR s people-centred EWS. Second, we analyze the main international EWSs for food security risk, i.e. the Integrated Phase Classification, the Famine Early Warning System Network, the Vulnerability Assessment and Mapping, and the Global Information Early Warning System with regard to their information content, monitoring characteristics and communication strategies, and link these to their response capacity. We show that EWS monitor a variety of indicators, covering the availability and accessibility components of food security. Even though EWSs could expand their country coverage and spatial detail, we find that information on accessibility indicators is missing for multiple countries, particularly for those involved in complex emergencies. Furthermore, none of the EWS examined provide real-time information, as they fail to integrate communication technologies and the internet as source for bottom-up information and communities at risk, both as an information source and recipient of warnings.

description: The dilemma most governments face is how to balance implementation of various policies in the absence of research-based evidence of their impact. For the Malawi Government, the dilemma is how to balance budgetary support to farm input subsidies and other policies in the agricultural sector. This article estimates the effects of the residence of an agricultural extension officer in the community, receipt of extension advice and subsidised fertiliser on household dietary diversity, dietary variety and per capita consumption of macro and micro nutrients using the Intergrated Household Panel Survey data of 2010 and 2013 for Malawi. Empirical analyses employ fixed effects models and the results suggests that the residence of an agricultural extension officer in the community has positive effects on food and nutrition security. The results also show consistently insignificant effects of subsidised fertiliser and receipt of extension advice. However, subsidised fertiliser is found to have positive effects only on food security when it is combined with receipt of extension advice. These results suggests that policies which focus on promoting availability of agricultural extension officers in the community might be more effective and efficient in addressing food and nutrition insecurity and demonstrate the importance of synergies in policies' implementation.

description: Motivated by certain concepts introduced by the Refined Algebraic Quantization formalism for constrained systems which has been successfully applied within the context of Loop Quantum Gravity, in this paper we propose a phase space implementation of the Dirac quantization formalism to appropriately include systems with constraints. In particular, we propose a physically prescribed Wigner distribution which allows the definition of a well-defined inner product by judiciously introducing a star version of the group averaging of the constraints. This star group averaging procedure is obtained by considering the star-exponential of the constraints and then integrating with respect to a suitable measure. In this manner, the proposed physical Wigner distribution explicitly solves the constraints by including generalized functions on phase space. Finally, in order to illustrate our approach, our proposal is tested in a couple of simple examples which recover standard results found in the literature.

description: Using the previously introduced modified discrete dipole approximation (DDA) method by applying the full details of the nanoparticle and its surrounding environment, the detection sensitivity of molecules by plasmonic Rod-based nanosensors, including U-shaped and Rod-shaped structures, was investigated. In the calculations, the two factors of the magnitude of the wavelength shift and the ability to distinguish molecules with similar properties were of significant interest. The results indicated that the sensitivity of Rod-based nanostructures is significantly higher than that of spherical nanoparticles. Among the plasmonic Rod-based nanosensors, the silver U-shaped structure performs better than others. The wavelength shift of the absorption spectrum of different nanosensors for a given molecule was very different, making it possible to detect very similar molecules from each other by testing different sensors.

description: Tribe Anoplognathini  (Figs 3, 9, 14; Tables 3, 7)
 The tribe Anoplognathini is found in Australia and from central Mexico to southern South America. In the New World, the tribe includes five genera: Aulacopalpus, Brachysternus, Hylamorpha, Platycoelia, and Phalangogonia (Smith 2002). The only genus of this tribe that is present in Ecuador is Platycoelia, which includes 19 Ecuadorian species (Table 3).
 In Ecuador, members of Anoplognathini are distributed from 300 to 4200 m (Fig. 9). This tribe is found in all zoogeographic areas on both sides of the Andes and reaches its highest diversity in temperate areas from 2000 to 3000 m. Platycoelia butleri Smith and P. furva Smith are restricted to the temperate area (Table 3). Platycoelia lutescens, P. galerana Smith, P. parva, and P. quadrilineata Burmeister are distributed in the high Andes. Platycoelia parva is found at 4200 m, which is the highest altitude reached by any ruteline in Ecuador. The northwest and southwest tropical areas have low numbers of species (Table 3). Nine species of Anoplognathini are endemic to Ecuador: P. forcipalis Ohaus, P. furva, P. galerana, P. gaujoni Ohaus, P. intermedia Ohaus, P. paucarae Smith, P. penai Frey, P.sandia Smith, and P. traceyae Smith. The temporal distribution of Anoplognathini species is not well known. Based on collecting data, species of Anoplognathini have three peaks of abundance: one from January to March (with a high peak in February), another in June, and another from October to December (Fig. 3, Table 7). Adult activity increased in relation to rainfall (a noticeable increase occurred in November and December).

description: Muon spin relaxation ($μ$SR) and magnetic susceptibility measurements have been performed on the pure and diluted spin 1/2 kagomé system (Cu$_x$Zn$_{1-x}$)$_{3}$V$_{2}$O$_7$(OH)$_{2}$ 2H$_2$O. In the pure $x=1$ system we found a slowing down of Cu spin fluctuations with decreasing temperature towards $T \sim 1$ K, followed by slow and nearly temperature-independent spin fluctuations persisting down to $T$ = 50 mK, indicative of quantum fluctuations. No indication of static spin freezing was detected in either of the pure ($x$=1.0) or diluted samples. The observed magnitude of fluctuating fields indicates that the slow spin fluctuations represent an intrinsic property of kagomé network rather than impurity spins.

description: In recent decades, the northern states of Brazil have experienced high rates of agricultural productivity change and also high rates of deforestation. In this article we examine the impact of the former on the latter. We pose the question whether technical change has been biased toward or against forest preservation decreasing or increasing the amount of agricultural commodities that must be given up to preserve a unit of forest. Here we estimate the rate and biases of technical change for municipalities in the arc of deforestation in the Brazilian Amazon Forest, 2003 to 2015. We represent the production possibility frontier between agriculture and deforestation with a directional distance function with deforestation as an undesirable output. Our results differ by municipality, showing an average annual rate of technical change of 4.9%, and an average bias toward agricultural outputs relative to deforestation, thus reflecting increasing opportunity costs for marginal reductions in deforestation.

description: Water scarcity for various uses constitutes a major global concern affecting millions of people but the problem is more serious especially in Africa. In a situation where farmers do not pay for irrigation water use, this study aims to investigate demand-side issues by eliciting farmers willingness to pay (WTP) for access to irrigation water. We employ choice experiment and contingent valuation methods to valuing access to irrigation water taking Ethiopia as a case in point. Unlike previous studies, the study covers users and non-users of irrigation water using the same baseline (status quo) conditions and compares the preferences of these two groups. Four attributes identified in the choice experiment are number of crop seasons, frequency of watering in a season, crop type and payment. Results show that marginal WTP was Birr 17.7, 261.8 and 87.6 for number of crop seasons, watering frequency in a season and crop type respectively. Our estimate of WTP of farmers for operation and maintenance of irrigation schemes per hectare of irrigated land range from Birr 738 (from the CE) to Birr 784 (from the CVM). We find non-users are willing to pay more in general as well as for the number of crop seasons specifically.

description: The aim of this study was to analyze the structure and concentration indexes of the sugarcane market in the South-Central region of Brazil. Based on the concept of relevant or antitrust market, used by leading competition defense agencies worldwide, we were able to reach the conclusion that the sugarcane buyers' market is much more restricted in comparison with the market defined in the empirical literature, thus underestimating the actual market concentration indexes. Our results indicate that the sugarcane markets are restricted to local markets and, in general, these markets are structured in two ways: monopsonies or oligopsonies. All the concentration indexes found were not only high, but also much higher than the results of other empirical studies. The results however do not indicate that such indexes are decreasing over time as unarguably as exposed in the literature.

description: Unitary operations are the building blocks of quantum programs. Our task is to design effcient or optimal implementations of these unitary operations by employing the intrinsic physical resources of a given n-qubit system. The most common versions of this task are known as Hamiltonian simulation and gate simulation, where Hamiltonian simulation can be seen as an infinitesimal version of the general task of gate simulation. We present a Lie-theoretic approach to Hamiltonian simulation and gate simulation. From this, we derive lower bounds on the time complexity in the n-qubit case, generalizing known results to both even and odd n. To achieve this we develop a generalization of the so-called magic basis for two-qubits. As a corollary, we note a connection to entanglement measures of concurrence-type.

description: Observed mass-to-light ratios (M/L) of metal-rich globular clusters (GCs) disagree with theoretical predictions. This discrepancy is of fundamental importance since stellar population models provide the stellar masses that underpin most of extragalactic astronomy, near and far. We have derived radial velocities for 1,622 stars located in the centres of 59 Milky Way GCs - twelve of which have no previous kinematic information - using integral-field unit data from the WAGGS project. Using N-body models, we then determine dynamical masses and M/L ratios for the studied clusters. Our sample includes NGC 6528 and NGC 6553, which extend the metallicity range of GCs with measured M/L up to [Fe/H] ~ -0.1 dex. We find that metal-rich clusters have M/L more than two times lower than what is predicted by simple stellar population models. This confirms that the discrepant M/L-[Fe/H] relation remains a serious concern. We explore how our findings relate to previous observations, and the potential causes for the divergence, which we conclude is most likely due to dynamical effects.

Magnetic Inflation and Stellar Mass. V. Intensification and saturation of M dwarf absorption lines with Rossby number

description: In young sun-like stars and field M dwarf stars, chromospheric and coronal magnetic activity indicators such as H$α$, X-ray and radio emission are known to saturate with low Rossby number ($Ro \lesssim 0.1$), defined as the ratio of rotation period to convective turnover time. The mechanism for the saturation is unclear. In this paper, we use photospheric Ti I and Ca I absorption lines in $Y$ band to investigate magnetic field strength in M dwarfs for Rossby numbers between 0.01 and 1.0. The equivalent widths of the lines are magnetically enhanced by photospheric spots, a global field or a combination of the two. The equivalent widths behave qualitatively similar to the chromospheric and coronal indicators: we see increasing equivalent widths (increasing absorption) with decreasing $Ro$ and saturation of the equivalent widths for $Ro \lesssim 0.1$. The majority of M dwarfs in this study are fully convective. The results add to mounting evidence that the magnetic saturation mechanism occurs at or beneath the stellar photosphere.

description: Tribe Geniatini  (Figs 4, 10, 15; Tables 4, 7)
 The tribe Geniatini is exclusively Neotropical, and it occurs from Mexico to northern Argentina and Brazil. Only one species (Geniates leptopus Ohaus) is known from Chile (Villatoro 2001). Species of geniatines inhabit semideciduous forests and cloud forests, but little is known of their natural history. In the Neotropics, the tribe Geniatini includes 13 genera and 323 described species (Villatoro 2001). In Ecuador, the Geniatini includes 5 genera with 28 species (7 unnamed). There is little information about the distribution of the species due to lack of collecting, incomplete label data, and lack of specimens identified to species.
 This group is poorly known taxonomically. Revisions and keys to species are needed for all the genera, and the taxonomic position of some genera and species needs clarification. Based on the distributional data of geniatines in Ecuador, members of this tribe are predominantly distributed in the eastern tropical and subtropical areas (at elevations of 460–1200 m) (Fig. 10). The highest altitude reached by geniatine scarabs is 2800 m (Bolax pulla (Latreille)). Ecuadorian Geniatini includes 16 species that are endemic (Table 4). Endemic geniatines occupy the eastern subtropical and tropical zones (Leucothyreus anaemicus Ohaus, L. cupripennis Ohaus, L. jivarus Ohaus, Lobogeniates abdominalis Ohaus, L. hirtus Ohaus and Trizogeniates schmidti (Ohaus)), and the temperate zone (Leucothyreus davisi Ohaus) (Table 4).
Few specimens of the Geniatini material examined have complete collecting data and so inferences of temporal distributions are not possible. However, based on limited available data, geniatines have one peak of abundance during March (Fig. 4, Table 7). An increase in adult activity may occur during December and January, but more sampling is needed to verify this.

description: Motivated by recent experiments of Pillarisetty {\it et al}, \prl {\bf 90}, 226801 (2003), we present a theory of drag in electronic double layers at low electron concentration. We show that the drag effect in such systems is anomolously large, it has unusual temperature and magnetic field dependences accociated with the Pomeranchuk effect, and does not vanish at zero temperature.
