description: We present observations of the C-band $1_{10}-1_{11}$ (4.8 GHz) and Ku-band $2_{11}-2_{12}$ (14.5 GHz) K-doublet lines of H$_2$CO and the C-band $1_{10}-1_{11}$ (4.6 GHz) line of H$_2$$^{13}$CO toward a large sample of Galactic molecular clouds, through the Shanghai Tianma 65-m radio telescope (TMRT). Our sample with 112 sources includes strong H$_2$CO sources from the TMRT molecular line survey at C-band and other known H$_2$CO sources. All three lines are detected toward 38 objects (43 radial velocity components) yielding a detection rate of 34\%. Complementary observations of their continuum emission at both C- and Ku-bands were performed. Combining spectral line parameters and continuum data, we calculate the column densities, the optical depths and the isotope ratio H$_2$$^{12}$CO/H$_2$$^{13}$CO for each source. To evaluate photon trapping caused by sometimes significant opacities in the main isotopologue's rotational mm-wave lines connecting our measured K-doublets, and to obtain $^{12}$C/$^{13}$C abundance ratios, we used the RADEX non-LTE model accounting for radiative transfer effects. This implied the use of the new collision rates from \citet{Wiesenfeld2013}. Also implementing distance values from trigonometric parallax measurements for our sources, we obtain a linear fit of $^{12}$C/$^{13}$C = (5.08$\pm$1.10)D$_{GC}$ + (11.86$\pm$6.60), with a correlation coefficient of 0.58. D$_{GC}$ refers to Galactocentric distances. Our $^{12}$C/$^{13}$C ratios agree very well with the ones deduced from CN and C$^{18}$O but are lower than those previously reported on the basis of H$_2$CO, tending to suggest that the bulk of the H$_2$CO in our sources was formed on dust grain mantles and not in the gas phase.

description: It is natural to ask whether "positivity" of white noise operators can be discussed in some sense and characterized. To answer this question, we consider the Gel'fand triple over the Complex Gaussian space $(\ce'_c,\m_c)$, i.e. $\ce'_c=\ce'+i\ce'$ equipped with the product measure $\m_c=\m'\times\m'$ where $\m'$ is the Gaussian measure on $\ce'$ with variance 1/2 (Section \ref{sec:2-2}). Following AKK's Legendre transform technique, we have $\cw_{u_1,u_2}\subset L^2(\ce'_c,\m_c)\subset [\cw]^{*}_{u_1,u_2}$ for functions $u_1,u_2\in C_{+,1/2}$ satisfying (U0)(U2)(U3). Several examples for $u_1, u_2$ are given in Section \ref{sec:2-3}. We remark that Ouerdiane \cite{oue} studied a special case $u_1(r^2)=u_2(r^2)=\exp(k^{-1}r^k)$, where $1\leq k\leq 2$. In Section \ref{sec:3}, the characterization theorem for measures can be extended to the case of positive product Radon measures on $\ce'\times \ce'$. In addition, the notion of pseudo-positive operators is naturally introduced via kernel theorem and characterized by an integrability condition. Lemma \ref{lem:3-2} plays crucial roles in Section \ref{sec:3}.

description: Improving the effectiveness of agricultural markets for economic growth and poverty reduction has been a central focus for development initiatives, particularly in Sub-Saharan Africa. Staple crops with low input requirements and drought tolerance, such as cassava, are being promoted for market development due to their accessibility for poor smallholder farmers. Narratives often equate commercialization of cassava to benefits for women, as cassava is commonly labelled a ‘women’s crop’. However, little is known about whether or how women can engage with new cassava commercial opportunities and the livelihood outcomes from this, particularly given the importance of cassava for food security. Findings from fieldwork in Nigeria and Malawi identify cassava value chains that offer different opportunities and challenges for women, which are often overlooked in agricultural development narratives. Women can gainfully participate in new commercial cassava opportunities while maintaining, if not increasing, food security. However, this is highly dependent on gender norms and household relations. Greater attention is required to these more difficult aspects of gender analysis in development projects to ensure women’s integration and benefit from agricultural markets.

description: This study examines the effects of smallholder milk market participation on household and intra-household dietary diversity and on nutritional status of young children in Ethiopia. Using the FAO dietary diversity questionnaire, 164 households were followed for two consecutive days and all food items consumed by five household members were recorded. T-test and propensity score matching were used to analyze the data. Milk market participant households have significantly higher levels of milk production, household income, dietary diversity and nutritional status of young children. Despite significant differences in milk production between market participant and non-participant households, no significant differences were found with regard to animal source food consumption in general and milk consumption in particular. However, dietary diversity and nutritional status of children under five is better in participant households, thus indicating that smallholder market participation is positively associated with food security and nutritional status of farm households in rural Ethiopia.

description: We compare the electron dynamics at monocrystalline Cu(111), Au(100) and Pd(111) precursor substrates with vicinal nanosteps. The unoccupied bands of a surface superlattice are populated \textit{via} the resonant charge transfer (RCT) between the surface and a H$^-$ ion that flies by at grazing angles. A quantum mechanical wave packet propagation approach is utilized to simulate the motion of the active electron where time-evolved wave packet densities are used to visualize the dynamics through the superlattice. The survived ion fraction in the reflected beam generally exhibits modulations as a function of the vicinal terrace size and shows peaks at those energies that access the image state subband dispersions. However, differences in magnitudes of the ion-survival as a function of the particular substrate selection as well as the ion-surface interaction time based on the choice of two ion-trajectories are examined. A square well model producing standing waves between the steps on the surface explains well the energies of the maxima in the ion survival probability for all the metals considered, indicating that the primary process of confinement induced subband formation is rather robust. The work may motivate measurements and applications of shallow-angle ion-scattering spectroscopy to access electronic substructures in periodically nanostructured surfaces.

description: An important modulation technique for Internet of Things (IoT) is the one proposed by the LoRa allianceTM. In this paper we analyze the M-ary LoRa modulation in the time and frequency domains. First, we provide the signal description in the time domain, and show that LoRa is a memoryless continuous phase modulation. The cross-correlation between the transmitted waveforms is determined, proving that LoRa can be considered approximately an orthogonal modulation only for large M. Then, we investigate the spectral characteristics of the signal modulated by random data, obtaining a closed-form expression of the spectrum in terms of Fresnel functions. Quite surprisingly, we found that LoRa has both continuous and discrete spectra, with the discrete spectrum containing exactly a fraction 1/M of the total signal power.

description: It is often said that the announcement of new urban rail opening affects real estate prices since the market speculates on the future enhancement of accessibility. Many empirical studies confirm that the prices have increased even before the rail openings. However, few investigate when and where price increments begin. This study proposes an analysis approach to extract the area and period of influence of rail opening on real estate market using Fused-MCP on the new subway opening in Sendai, Japan. The results show that the prices have increased sharply after the opening, and the announcement effect has been minimal.

description: Over the last several decades, participation in producer organizations has become a key principle of development, enabling people’s empowerment, inclusiveness, and facilitating democracy. Producer organizations have become crucial actors to provide services to the rural poor, and women’s participation and leadership in producer organizations has become a focus of rural and agricultural development efforts. This review paper aims to document the factors that hinder women’s participation in producer organizations. The review identifies several factors as major barriers for women’s participation, including: socio-cultural norms; women’s double burden and triple roles; women’s status, age and previous membership in organizations; access to assets and resources; educational level; organizations’ rules of entry, and; legal and policy environment. The paper also provides a review of lessons and good practice that can be applied by Agricultural Research for Development institutions. The review identified strategies for strengthening women’s participation in producer organizations at the individual/household, community/producer organization, and policy level. The review found that at the individual/household level, strategies to improve individual capabilities and intra-household relations were crucial for promoting women’s participation and leadership in producer organizations. Similarly, at the producer organizational level strategies to ensure that the structures and governance mechanisms are more gender sensitive, and promote women’s inclusion, are crucial. Equally important are policies for promoting gender-sensitive producer organizations and specific measures geared at promoting women’s active participation in producers’ organizations.

description: The private entrepreneurs are not forced to limit themselves to the standard auction rules, and in case of the procurement auctions one can observe many hybrid or quasi-auction rules spontaneously introduced. The paper analyzes two of them, that are based on the common assumption: the second-best bidder is given an additional right to improve her initial bid, and therefore win the auction. The focus of the paper is on the analysis of price and allocative efficiency of such modifications, to determine whether they can serve as an alternative to the standard auction rules. Theoretical analyses, followed by the laboratory experiments, provide no proof for that conclusion though, as none of the rules under study beats the classical first-price sealed-bid auction.

description: The evolution and the statistical properties of an infinite gravitating system represent an interesting and widely investigated subject of research. In cosmology, the standard approach is based on equations of hydrodynamics. In the present paper, we analyze the problem from a different perspective, which is usually neglected. We focus our attention on the fact that at small scale the distribution is point-like, or granular, and not fluid-like. The basic result is that the discrete nature of the system is a fundamental ingredient to understand its evolution. The initial configuration is a Poisson distribution in which the distribution of forces is governed by the Holtsmark function. Computer simulations show that the structure formation corresponds to the shift of the granularity from small to large scales. We also present a simple cellular automaton model that reproduces this phenomenon.

description: Generation of ultrarelativistic polarized positrons during interaction of an ultrarelativistic electron beam with a counterpropagating two-color petawatt laser pulse is investigated theoretically. Our Monte Carlo simulation based on a semi-classical model, incorporates photon emissions and pair productions, using spin-resolved quantum probabilities in the local constant field approximation, and describes the polarization of electrons and positrons for the pair production and photon emission processes, as well as the classical spin precession in-between. The main reason of the polarization is shown to be the spin-asymmetry of the pair production process in strong external fields, combined with the asymmetry of the two-color laser field. Employing a feasible scenario, we show that highly polarized positron beams, with a polarization degree of $ζ\approx 60\%$, can be produced in a femtosecond time scale, with a small angular divergence, $\sim 74$ mrad, and high density $\sim 10^{14}$ cm$^{-3}$. The laser-driven positron source, along with laser wakefield acceleration, may pave the way to small scale facilities for high energy physics studies.

Theoretical models derived in the framework of the Generalized Parton Distributions show that this angular distribution receives only contributions from the interference between the isoscalar channel I=0 and the isovector channel I=1.

description: With a view towards future applications in nuclear physics, the fermion realization of the compact symplectic sp(4) algebra and its q-deformed versions are investigated. Three important reduction chains of the sp(4) algebra are explored in both the classical and deformed cases. The deformed realizations are based on distinct deformations of the fermion creation and annihilation operators. For the primary reduction, the su(2) sub-structure can be interpreted as either the spin, isospin or angular momentum algebra, whereas for the other two reductions su(2) can be associated with pairing between fermions of the same type or pairing between two distinct fermion types. Each reduction provides for a complete classification of the basis states. The deformed induced u(2) representations are reducible in the action spaces of sp(4) and are decomposed into irreducible representations.

description: There is a long standing discussion of whether expected utility theory (EU) or prospect theory (PT) best explains the behavior with respect to risky choices. Often these two approaches are compared by putting questions to students in laboratory situations. Here we try to investigate stated preferences of farmers who are functioning under high levels of risk in real life. As part of a larger survey, four binary choices were offered during two successive years. The experimental test was performed 199 farmers in two districts in Tigray, Northern Ethiopia. Three items were central in comparing the risk attitude according to EU and PT: the asymmetry of risk perceptions, the independence axiom and the shape of the utility function. The farmers in the two different districts (Enderta and Hintalo-Wajerat) differed significantly in their risk attitude. Enderta farmers were significantly risk-averse for gains and risk-seeking for losses; their preferences conformed to the hypothesis of prospect theory. However, expected utility maximization was found to be an appropriate descriptor for Hintalo-Wajerat farmers. In order to identify the factors that affect farmer’s preferences, a binary choice model was used. Household income was found to be positive and significant while value of livestock had the expected negative sign and was directly related to a decrease in risk aversion. Knowledge of farmers’ attitude toward risk has important implications for policy makers to devise policies that can overcome the critical constraints they face in meeting their basic needs.

description: The existing pool of evidence on the growth effects of investment and trade, as well as the reciprocal effects, is hardly sufficient, rendering their connections to remain inconclusive. The insufficiency of such studies is chronic when it comes to the Ethiopian economy. The investment, trade and growth connections in the Ethiopian economy have not been well researched, calling for such kinds of studies. Targeting at characterising the patterns of impact flows between investment, trade and growth in Ethiopia and contributing a little in filling some aspects of the lacuna, this study becomes a short-run causality analyses on their dynamic links using time series data over the period 1955-2003. According to the estimated VAR results, there is no feedback between any pair of the variables, out of the 3 hypothesised dynamic feedback links. Nonetheless, we have observed two uni-directional positive causalities that run from economic growth to enhanced trade openness and from the latter to investment. However, the evidence should not be interpreted as investment and trade do not contribute to growth. Rather, it could be signalling the low investment and trade performances of the country despite the unknown minimum thresholds of the rate of investment and trade openness for their respective impacts to be recognizable. Hence, measures that improve the performance of both activities, their linkages and the contribution of trade to investment could help the economy to build its productive capacity and then to grow faster.

description: Universality in cellular automata theory is a central problem studied and developed from their origins by John von Neumann. In this paper, we present an algorithm where any Turing machine can be converted to one-dimensional cellular automaton with a 2-linear time and display its spatial dynamics. Three particular Turing machines are converted in three universal one-dimensional cellular automata, they are: binary sum, rule 110 and a universal reversible Turing machine.

description: We study the influence of surface anisotropy on the zero-temperature hysteretic properties of a small single-domain magnetic particle, and give an estimation of the anisotropy constant for which deviations from the Stoner-Wohlfarth model are observed. We consider a spherical particle with simple cubic crystalline structure, a uniaxial anisotropy for core spins and radial anisotropy on the surface, and compute the hysteresis loop by solving the local Landau-Lifshitz equations for classical spin vectors. We find that when the surface anisotropy constant is at least of the order of the exchange coupling, large deviations are observed with respect to the Stoner-Wohlfarth model in the hysteresis loop and thereby the limit-of-metastability curve, due to the non-uniform cluster-wise reversal of the magnetisation.

description: Assessing nitrogen (N) mineralization potential of manure is an important precursor for ensuring nutrient use efficiency. N mineralization of agouti and cattle manure was assessed after application to four contrasting soils, incubated for 35 days. Total Kjeldahl nitrogen (TKN) fluctuated over the incubation period and was affected by both soil and manure type. Mineralization was greater in agouti versus cattle manure, with the latter showing immobilization between sampling days 3 and 14. TKN was greatest in Princes Town soil. Ammonium (NH4+) content fluctuated similarly to TKN. Values were significantly higher in the strongly acid soils. Nitrate (NO3-) content decreased with time, stabilising at values just below 50 mg/kg. For the first two sampling times, agouti manure contained significantly higher values compared to cattle manure. Agouti manure can be applied as a soil amendment with consideration of the N supplying potential.

description: Soil is a part of the solution to the greatest dilemmas of our time. It plays a critical role in mitigating the effects of climate change, increasing farm productivity and food security, and may hold the answers to eradicating antibiotic resistance. If we truly want to achieve the Sustainable Development Goals we’ve set for ourselves, we can’t afford to not focus on soil health. Healthy soils are crucial for ensuring the continued growth of natural and managed vegetation, providing feed fiber, fuel, medicinal products and other ecosystem services such as climate regulation and oxygen

description: We consider an optical probe that interacts with an ensemble of rare earth ions doping a materialin the shape of a cantilever. By optical spectral hole burning, the inhomogeneously broadenedtransition in the ions is prepared to transmit the probe field within a narrow window, but bendingof the cantilever causes strain in the material which shifts the ion resonances. The motion of thecantilever may thus be registered by the phase shift of the probe. By continuously measuringthe optical field we induce a rapid reduction of the position and momentum uncertainty of thecantilever. Doing so, the probing extracts entropy and thus effectively cools the thermal state ofmotion towards a known, conditional oscillatory motion with strongly reduced thermal fluctuations.Moreover, as the optical probe provides a force on the resonator proportional to its intensity, it ispossible to exploit the phase shift measurements in order to create an active feedback loop, whicheliminates the thermal fluctuations of the resonator. We describe this system theoretically, andprovide numerical simulations which demonstrate the rapid reduction in resonator position andmomentum uncertainty, as well as the implementation of the active cooling protocol.

description: Option pricing is mainly based on ideal market conditions which are well represented by the Geometric Brownian Motion (GBM) as market model. We study the effect of non-ideal market conditions on the price of the option. We focus our attention on two crucial aspects appearing in real markets: The influence of heavy tails and the effect of colored noise. We will see that both effects have opposite consequences on option pricing.

description: Control by traffic signals is an important factor for short-term traffic state prediction at an intersection. Deep learning, which has the capability to capture nonlinear relationships, is achieving superior performance for an extensive range of prediction problems. Consequently, its application to traffic state prediction is expected. This study proposes a deep learning model that predicts traffic volume of the target road link downstream of an intersection, using the time-series traffic volume observation of the target link and multiple upstream links, and traffic signal control information at the intersection. The proposed model was validated with traffic volume data obtained from a traffic flow simulator. The validation results showed that the traffic volume data from upstream links and traffic signal control information contributed to improvements in prediction accuracy. However, when the signal control patterns of validation data were different from those of training data, the traffic signal control information made prediction accuracy worse.

description: Space-based photogrammetry has benefitted from significant advancements recently, with progress in software, analytical techniques, and a surge in image availability. However, no photogrammetric products can be considered perfect. Estimates of error from photogrammetric modelling are thus important to characterise when faced with the various processing workflows available. This study quantifies and compares errors in photogrammetric products from very high-resolution Pléiades sensors when processed with or without ground control points (GCPs). Furthermore, the availability of an image triplet allowed bi-stereo and tri-stereo restitution scenarios to be compared for each case.

description: Jamaica’s agricultural sector, largely dominated by small farmer families, plays an important role in contributing to National Food Security. Small farmers in the ‘breadbasket’ parish of St. Elizabeth, in particular, are important producers of scallion, onion and other crops. Recent advances in onion production are significant elements leading to improvements in their livelihoods. However, these improvements have been threatened by increasingly frequent and serious outbreaks of the Beet Armyworm (BAW) (Spodoptera exigua Hübner) infestations. Despite efforts by the farmers and government agencies to control the outbreaks in 2009-2012, the devastation has continued to erode the progress made and the livelihoods of the farmers (J$140 million/US$1.4 million). This is largely due to an inability to provide appropriate production practices and management options to farmers. In response to a request from the Government of Jamaica to the Food and Agriculture Organization (FAO), the project Strengthening a National Beet Armyworm Management Programme (TCP-JAM-3401) was formulated and approved in 2012. Activities, which began in January 2013 include consultative and participatory processes among national, international experts and farming communities, towards the development of a strategy to adopt area-wide, integrated and comprehensive approaches to management of the BAW infestations. These are expected to contribute significantly to improved and sustained production. FAO assistance includes the development of a forecasting tool (FT) to assist farmers in making effective management decisions based on climatic conditions, as well as support to undertake an extensive Farmer Field School (FFS) programme, training both national Extension personnel and farmers in Training of Trainers workshops. It is anticipated that this approach would enable more timely and appropriate responses to BAW infestations and an improved/effective management of the BAW, as well as facilitate the institutionalization of FFS for direct empowerment of farmer communities and groups. The paper reports on progress made over the past 18 months, highlighting achievements under each component of the project.
