description: RealSense1 is a pilot-project aiming to develop a new generation of low-cost sensors for monitoring of advanced cell culture parameters: biomass concentration – key variable in cell cultures and nutrients/metabolites: glucose, glutamine, peroxide, lactate and ammonia. Sensors can potentially be used for media recycling (in combination with filtering). RealSense1 implements a scale- down approach focusing on microfluidic cell culture - microbioreactors (Lab on a Chip-LOC).
 On September 5th, Dr Ivana Gadjanski, coordinator of the RealSense1 project, held poster presentation at The Good Food Conference in San Francisco, USA, where she presents preliminary results for impedimetric biomass sensor in microbioreactor and initial enzyme immobilization.

description: We realize the current algebra of a Kac-Moody algebra as a quotient of a semi-direct product of the Kac-Moody Lie algebra and the free Lie algebra of the Kac-Moody algebra. We use this realization to study the representations of the current alg ebra. In particular we see that every ad-invariant ideal in the symmetric algebra of the Kac-Moody algebra gives rise in a canonical way to a representation of the current algebra. These representations include certain well-known families of representations of the current algebra of a simple Lie algebra. Another family of examples, which are the classical limits of the Kirillov-Reshe tikhin modules, are also obtained explicitly by using a construction of Kostant. Finally we study extensi ons in the category of finite dimensional modules of the current algebra of a simple Lie algebra.

description: The paper analyses the factors that affect smallholder farmers choice of soil fertility management options in Malawi using a two-stage maximum likelihood estimation procedure. Using results from the Double-Hurdle model, the paper estimates the probabilities and intensities of fertilizer application conditional on choice of inorganic fertilizer. The findings indicate that relative wealthy indicators, human capital, credit and market access, food security index and land pressure are the main factors that greatly influence farmers choice and intensity of input investment. Although there is a high and positive correlation between probability of adoption and intensity of application, factors that influence adoption are not necessarily the same as those that influence the intensity of application, conditional on adoption. The paper concludes with policy and research implications aimed at informing the debate on enhancing sustainable soil fertility management among smallholder farmers in Malawi.

description: The core problem of visual multi-robot simultaneous localization and mapping (MR-SLAM) is how to efficiently and accurately perform multi-robot global localization (MR-GL). The difficulties are two-fold. The first is the difficulty of global localization for significant viewpoint difference. Appearance-based localization methods tend to fail under large viewpoint changes. Recently, semantic graphs have been utilized to overcome the viewpoint variation problem. However, the methods are highly time-consuming, especially in large-scale environments. This leads to the second difficulty, which is how to perform real-time global localization. In this paper, we propose a semantic histogram-based graph matching method that is robust to viewpoint variation and can achieve real-time global localization. Based on that, we develop a system that can accurately and efficiently perform MR-GL for both homogeneous and heterogeneous robots. The experimental results show that our approach is about 30 times faster than Random Walk based semantic descriptors. Moreover, it achieves an accuracy of 95% for global localization, while the accuracy of the state-of-the-art method is 85%.

description: Vegetable plays important roles in the socio-economic development in West Africa. It contributes to insuring food security, provides raw materials for local industries, generates foreign exchange and provides employment and incomes for most of the population. However some health hazards are caused by the misuse of chemical on vegetable. This study is undertaken within the framework of the research project: Public-private partnerships for development and implementation of entomopathogenic viruses as biopesticides for key lepidopteran pests in Ghana and Benin. It assesses the potential market of organic vegetables and analyse consumers awareness and perceptions of chemical pesticide residues in vegetables and assess the premium levels that consumers are willing to pay for chemical free vegetables. Data were collected through a formal questionnaire on consumers perceptions of produce quality problems, their level of awareness of heavy chemical pesticide use on vegetable and their willingness to pay for a vegetable if it is chemical free. A Hedonic-pricing model was used to identify the key factors most likely to affect consumers willingness to pay for bio-vegetables. The results show that consumers are aware of the heavy use of chemicals on vegetables. The level of awareness of health hazard linked to chemical pesticides among consumers is more widely spread. The characteristics that consumers are looking for in assessing the quality of vegetable are: damage free, freshness, size, bright colour and hardness. Consumers are willing to pay more than 50% as price premium for chemical free vegetable. The most likely factors influencing consumers willingness to pay for chemical free vegetable are the socio-professional category acting as a proxy for income level, the awareness of chemical residue, the availability, the label and the taste. In conclusion, this study showed that there is a consistent potential demand for organic vegetables if they meet characteristics above mentioned.

description: Maize is the staple food crop and source of income for majority of the Kenyan population and many sub-Saharan African countries. The increasing Kenyan population demands an increase in maize production if intermittent food deficits have to be averted. Since the introduction of improved maize varieties in mid-1960, the start of Green Revolution period, maize yields increased drastically up to 1970s and started declining from 1980s to-date. The key contributory factors are nutrient mining, sub-optimal input use and insect pest damage. Of the insect pests, stalk borer is of economic importance. Currently, KARI and CIMMYT are developing maize varieties that are tolerant to stalk borer damage. In order to evaluate the potential impact of these interventions economics of stalk borer control at farm level was evaluated. Surveys complemented with on-farm trials were executed in six major maize growing zones of Kenya. Farmers were randomly selected and a sample-frame established after which a total of 1854 households were randomly selected using random sampling technique. Each household was interviewed using structured questionnaire. Data on method of stalk borer control and the type insecticides used was collected. Partial budget and economic surplus models were used. The results indicated that very few farmers control stalk borer in maize despite significant stalk borer losses of about 15%. Therefore if Bt maize is introduced in Kenya it is likely to reduce these losses. This will benefit many hungry and poor Kenyans with improved household food supply and on farm incomes, in line with Government policy of food security and poverty eradication.

description: We present a maximal class of analytic functions, elements of which are in one-to-one correspondence with their asymptotic expansions. In recent decades it has been realized (B. Malgrange, J. Ecalle, J.-P. Ramis, Y. Sibuya et al.), that the formal power series solutions of a wide range of systems of ordinary (even non-linear) analytic differential equations are in fact the Gevrey expansions for the regular solutions. Watson's uniqueness theorem belongs to the foundations of this new theory. This paper contains a discussion of an extension of Watson's uniqueness theorem for classes of functions which admit a Gevrey expansion in angular regions of the complex plane with opening less than or equal to (\frac πk,) where (k) is the order of the Gevrey expansion. We present conditions which ensure uniqueness and which suggest an extension of Watson's representation theorem. These results may be applied for solutions of certain classes of differential equations to obtain the best accuracy estimate for the deviation of a solution from a finite sum of the corresponding Gevrey expansion.

description: Motivation: Standard algorithms for pairwise protein sequence alignment make the simplifying assumption that amino acid substitutions at neighboring sites are uncorrelated. This assumption allows implementation of fast algorithms for pairwise sequence alignment, but it ignores information that could conceivably increase the power of remote homolog detection. We examine the validity of this assumption by constructing extended substitution matrixes that encapsulate the observed correlations between neighboring sites, by developing an efficient and rigorous algorithm for pairwise protein sequence alignment that incorporates these local substitution correlations, and by assessing the ability of this algorithm to detect remote homologies. Results: Our analysis indicates that local correlations between substitutions are not strong on the average. Furthermore, incorporating local substitution correlations into pairwise alignment did not lead to a statistically significant improvement in remote homology detection. Therefore, the standard assumption that individual residues within protein sequences evolve independently of neighboring positions appears to be an efficient and appropriate approximation.

description: Tunable synthetic spin-orbit coupling (s-SOC) is one of the key challenges in various quantum systems, such as ultracold atomic gases, topological superconductors, and semiconductor quantum dots. Here we experimentally demonstrate controlling the s-SOC by investigating the anisotropy of spin-valley resonance in a silicon quantum dot. As we rotate the applied magnetic field in-plane, we find a striking nonsinusoidal behavior of resonance amplitude that distinguishes s-SOC from the intrinsic spin-orbit coupling (i-SOC), and associate this behavior with the previously overlooked in-plane transverse magnetic field gradient. Moreover, by theoretically analyzing the experimentally measured s-SOC field, we predict the quality factor of the spin qubit could be optimized if the orientation of the in-plane magnetic field is rotated away from the traditional working point.

The Role of Agriculture in the Development Process: Recent Experiences from Ghana

description: Economic policies have had important implications for the role of agriculture in the socio-economic development of Ghana because of agricultures dominance of the economy. The performance of the agricultural sector has generally directed the overall economic performance since independence. The policy of market deregulation in Ghana, including agricultural markets, has not achieved the expected results due to many constraints, the key of which are institutional failures and the slow response of the private sector to take up the agricultural input markets. These have been compounded by the rain-fed agriculture that is predominant in Ghana, such that bad rainfall years have been characterized by low harvests of staple food crops and high food prices, and vice versa. This has resulted in high price volatility during the post liberalization years. In addition, under developed rural financial markets make it such that farmers are unable to invest much in new technologies and agricultural land development, thereby increasing pressure on farmlands as population increases. The paper highlights the key role of agriculture, including environmental, poverty alleviation, food security, buffer, social viability, and cultural perceptions. The failure of policy to adequately address the myriad of problems confronting agriculture has been in part because of institutional failure, and in part due to bottlenecks in the distribution system. Future agricultural research and policies should therefore target developing rural institutions, in particular, agricultural institutions, to respond adequately to new technologies and improvements in agricultural production, processing and distribution.

description: The relevance of the Tremaine-Weinberg (TW) method is tested to measure the bar, spiral and inner structure pattern speeds using a gaseous velocity field. The TW method is applied to various simulated barred galaxies in order to demonstrate its validity in seven different configurations, including star formation or/and dark matter halo. The reliability of the different physical processes involved and of the various observational parameters are also tested. The simulations show that the TW method could be applied to the gaseous velocity fields to get a good estimate of the bar pattern speed, under the condition that regions of shocks are avoided and measurements are confined to regions where the gaseous bar is well formed. We successfully apply the TW method to the \ha velocity field of the Virgo Cluster Galaxy M100 (NGC 4321) and derive pattern speeds of 55+/-5 km/s/kpc for the nuclear structure, 30+/-2 km/s/kpc for the bar and 20+/-1 km/s/kpc for the spiral pattern, in full agreement with published determinations using the same method or alternative ones.

description: A gravitational-wave (GW) early-warning of a compact-binary coalescence event, with a sufficiently tight localisation skymap, would allow telescopes to point in the direction of the potential electromagnetic counterpart before its onset. This will enable astronomers to extract valuable information of the complex astrophysical phenomena triggered around the time of the merger. Use of higher-modes of gravitational radiation, in addition to the dominant mode typically used in templated real-time searches, was recently shown to produce significant improvements in early-warning times and skyarea localisations for a range of asymmetric-mass binaries. In this work, we perform a large-scale study to assess the benefits of this method for a population of compact binary merger observations. In particular, we inject 100,000 such signals in Gaussian noise, with component masses $m_1 \in \left[1, 60 \right] M_{\odot}$ and $m_2 \in \left [1, 3 \right] M_{\odot}$. We consider three scenarios involving ground-based detectors: the fifth (O5) observing run of the Advanced LIGO-Virgo-KAGRA network, its projected Voyager upgrade, as well as a proposed third generation (3G) network. We find that for fixed early warning times of $20-60$ seconds, the inclusion of the higher modes can provide localisation improvements of a factor of $\gtrsim 2$ for up to $\sim 60\%$ ($70 \%$) of the neutron star-black hole systems in the O5 (Voyager) scenario. Considering only those neutron star-black hole systems which can produce potential electromagnetic counterparts, such improvements in the localisation can be expected for $\sim 5-35\%$ $(20-50\%)$ binaries in O5 (Voyager), although the localisation areas themselves depend on the distances. For the 3G scenario, a significant fraction of the events have time gains of a minute to several minutes, assuming fiducial target localisation areas of 100 to 1000 sq. deg.

description: We report photometric and spectroscopic observations of the SU UMa-type dwarf novae, KS Ursae Majoris, during its 2003 February superoutburst. Modulations with a period of $0.07017\pm0.00021$ day, which is 3.3% larger than the orbital period, have been found during the superoutburst and may be positive superhumps. A maximum trough-to-peak amplitude of around 0.3 magnitude is determined for this superhump. The spectra show broad, absorption-line profiles. The lines display blue and red troughs which alternate in depth. The radial velocity curve of the absorption wings of H$β$ has an amplitude of $40\pm11$ km s$^{-1}$ and a phase offset of $0.12\pm0.03$. The $γ$ velocity of the binary is $3\pm9$ km s$^{-1}$ and varies on an order of 50 km s$^{-1}$ from day to day. From another clear evidence for a precessing eccentric disk, we obtain a solution to an eccentric outer disk consistent with theoretical works, which demonstrates the validity of the relation between superhumps and tidal effects. The inner part of the disk is also eccentric as evidenced by asymmetric and symmetric wings in the lines. Therefore, the whole disk is eccentric and the variation of $γ$ velocity and the evolutionary asymmetric line profiles could be criterions for an precessing eccentric accretion disk.

description: In times where multilateralism is to be the vector of free trade and the conveyor for liberalism, the phenomenon of regionalism has been increasing quiet steadily. Would it be a transitional step for their members towards multilateralism, or a manner to hide from it without being forgotten? Whatever the response may be to this question, regionalism has been "admitted" by the WTO in its article XXIV. The contradiction here is that regionalism is not always complying with WTO regulations such as including "substantially all trade" as well as "non discrimination" principle. The advantage of regional practices is its taking into account particularities and specifications of the member countries, what the WTO doesn't seem to consider. We argue that, as much the regional and multilateral levels are important for Africa and developing countries in general, a lot remains to be done, from the inside, to avoid being trapped in a process where control on the future of those countries would become impossible. In other words, enhancing capabilities and re-identifying resources to be able to master destiny.

description: We report optical reflectivity study on pure and boron-doped diamond films grown by a hot-filament chemical vapor deposition method. The study reveals the formation of an impurity band close to the top of the valence band upon boron-doping. A schematic picture for the evolution of the electronic structure with boron doping was drawn based on the experimental observation. The study also reveals that the boron doping induces local lattice distortion, which brings an infrared-forbidden phonon mode at 1330 cm$^{-1}$ activated in doped sample. The antiresonance characteristic of the mode in conductivity spectrum evidences the very strong coupling between electrons and this phonon mode.

description: Over the years, substantial investments in agricultural research have been made in sub-Saharan Africa. The few studies on research investments show impressive returns that are comparable to those achieved in developed countries. However, problems such as recurrent hunger, poverty, food insecurity and natural resource degradation continue to plague the region. Agricultural development arena is changing rapidly toward non-linear innovation systems of complex actor networks and multiple sources of innovations characterized by dynamic and iterative learning processes that constantly inform, renew and advance the state of the systems. Most actors and institutions are not linked effectively often from imaginary boundaries created by prescribed mandates and parochial interests. While more investments in research and development are required for the region, it is becoming increasingly difficult to justify them in the wake of competing needs in the face of shrinking national budgets. The few impact assessments that have been carried out in the region have been incidental and not linked to the research planning cycle implying that lessons from previous research efforts are not used when planning for subsequent research and development efforts. We are proposing impact orientation to track impact to the attainment of institutional and overall development goals. This calls in part for impact assessment to be made an integral part of planning, monitoring and evaluation along with appreciation of the impact chain and actors involved in the innovation process to demonstrate relevance to development goals and thus justify funding.

description: Acidic substances, specifically sulfur (S) compounds, derived from atmospheric deposition play a major role in the acidification of forest ecosystems. This study conducted field surveys to clarify a buffering system against seasonal large S inputs in a forested catchment in central Japan that has historically suffered from transboundary air pollution. Results showed that atmospheric S fluxes significantly increased in winter due to north-westerly seasonal winds from the Asian continent; fluxes were 1.1 and 0.3 kmolc ha−1 in the cold and warm seasons, respectively, due to the large effects of sea salt and transboundary air pollution. Despite the large seasonality within atmospheric deposition, SO42– concentrations in stream water (SW) were found to be relatively stable throughout the year. Similarly, S isotopic ratios (δ34S) in rainwater showed clear seasonal variation, increasing to 12‰ in winter and decreasing to 2‰ in summer, whereas the δ34S value of SW was stable year-round at ~9‰. Flux-weighted mean δ34S values for rainfall (RF), throughfall, stemflow, and SW were similar, i.e. 8.5, 9.5, 9.0, and 9.0‰, respectively. Both the δ34S values and the SO42– concentrations in RF and soil solutions appear to converge at values of SW, suggesting that atmospheric deposition is a primary S origin in SW. The sulfur adsorption-desorption in soil appears to mainly buffer the large sulfur input and prevent sudden acidification, whereas a relatively small biological sulfur cycle was suggested by litterfall. Possible disturbances within this buffering system should be carefully monitored under a changing climate.

description: An online cryogenic distillation system for the removal of krypton and radon from xenon was designed and constructed for PandaX-4T, a highly sensitive dark matter detection experiment. The krypton content in a commercial xenon product is expected to be reduced by 7 orders of magnitude with 99% xenon collection efficiency at a flow rate of 10 kg/h by design. The same system can reduce radon content in xenon by reversed operation, with an expected radon reduction factor of about 1.8 in PandaX-4T under a flow rate of 56.5 kg/h. The commissioning of this system was completed, with krypton and radon operations tested under respective working conditions. The krypton concentration of the product xenon was measured with an upper limit of 8.0 ppt.

description: Political and economic reforms have been implemented for a number of years to alter the institutional, infrastructural and financial/economic environment in which Ethiopian agriculture operates. Changing the environment in which agriculture operates may be an intermediate goal; at the end, the question remains; have the new reforms and policies had the capacity to improve the performance of the sector and its roles in the development process of the economy? And have they contributed to the generation of positive environmental externalities? In comparison to the two decades (1970s and 1980s) that precedes the reform of the 1990s. Ethiopian agriculture has been doing better since the reform. Total production of food crops has improved and the rate at which per-capita production has been declining is narrowed. Moreover, the volume of agricultural commodities exported has slightly improved; while new non-traditional commodities like flower have joined the list of exported commodities. But all those improvement have not been sufficient to lift up agricultures role in the development process of the Ethiopian economy nor have they brought a full and sustainable recovery to the sector. Ethiopian agriculture should still demonstrate the following desirable characteristics if it is able to serve as the engine of Ethiopian economic growth: it should grow at sufficiently higher rates over a number of years; any development in the sector should be able to improve rural labour productivity which is an important precondition to stimulate the non-agricultural sectors and transformation of the sector; the source of growth should principally originate from increased investment and efficient use of resources rather than from the use of additional scarce natural resources especially land, and; agriculture should be supported to establish strong and dynamic linkages with other sectors especially with the industry.
Calculation of the energy levels of Ge, Sn, Pb and their ions in the $V^{N-4}$ approximation

description: Energy levels of germanium, tin and lead together with their single, double and triple ionized positive ions have been calculated using the $V^{N-M}$ approximation suggested in the previous work (Dzuba, physics/0501032) (M=4 - number of valence electrons). Initial Hartree-Fock calculations are done for the quadruply ionized ions with all valence electrons removed. The core-valence correlations are included beyond the second-order of the many-body perturbation theory. Interaction between valence electrons is treated by means of the configuration interaction technique. It is demonstrated that accurate treatment of the core-valence correlations lead to systematic improvement of the accuracy of calculations for all ions and neutral atoms.

description: This paper seeks to inform the current "regulatory reform" effort in the U.S. by describing how information from risk assessments and cost-benefit analyses is used by decision makers in six other industrialized countries. In Japan, Germany, the United Kingdom, Netherlands, Canada and the European Union decision makers deal with uncertainties associated with risk assessments differently than in the U.S. They are less likely to employ "default assumptions" to bridge uncertainties and instead tailor risk evaluations to the chemical in question. Furthermore, while U.S. agencies are sometimes required to pair information from risk assessments with data from cost-benefit analyses in order to estimate how much it costs to stem or avert environmental and health effects, the decision makers in the six study regimes primarily use such information to set standards, screen chemicals, and identify potential substitutes for hazardous chemicals. Respondents in the study countries say that both quantitative risk assessment and cost-benefit analysis presently contain too many uncertainties to yield meaningful results. However, trade liberalization and shrinking government budgets are stirring greater interest abroad in how the U.S. conducts and uses risk assessments.

description: By applying the renormalization group equation, it has been shown that the effective potential $V$ in the massless $ϕ_4^4$ model and in massless scalar quantum electrodynamics is independent of the scalar field. This analysis is extended here to the massive $ϕ_4^4$ model, showing that the effective potential is independent of $ϕ$ here as well.

description: Monte Carlo integration using quantum computers has been widely investigated, including applications to concrete problems. It is known that quantum algorithms based on quantum amplitude estimation (QAE) can compute an integral with a smaller number of iterative calls of the quantum circuit which calculates the integrand, than classical methods call the integrand subroutine. However, the issues about the iterative operations in the integrand circuit have not been discussed so much. That is, in the high-dimensional integration, many random numbers are used for calculation of the integrand and in some cases similar calculations are repeated to obtain one sample value of the integrand. In this paper, we point out that we can reduce the number of such repeated operations by a combination of the nested QAE and the use of pseudorandom numbers (PRNs), if the integrand has the separable form with respect to contributions from distinct random numbers. The use of PRNs, which the authors originally proposed in the context of the quantum algorithm for Monte Carlo, is the key factor also in this paper, since it enables parallel computation of the separable terms in the integrand. Furthermore, we pick up one use case of this method in finance, the credit portfolio risk measurement, and estimate to what extent the complexity is reduced.

Obstacles to a Doubly Green Revolution

subject: developing country

description: Increasingly, conventional wisdom dictates that agrarian policy in developing countries should foster a "doubly green revolution" that both protects the environment and boosts output. Like the first green revolution, such a transformation will entail convincing millions of farmers to adopt new practices and, as a result, will confront well-documented barriers to technological change in developing-country agriculture. It will also face a number of new obstacles, including a divergence between the interests of policymakers and farmers, a policy environment biased in favor of input-intensive agriculture, and the fact that many environmentally friendly technologies entail relatively high set-up costs. At least in the short run, institutional constraints will limit the contribution of agricultural biotechnology to overcoming these obstacles. Hence, the first green revolution may serve as an overly optimistic model for a shift to a more sustainable agriculture.

description: The modules of logarithmic derivations for the (extended) Catalan and Shi arrangements associated with root systems are known to be free. However, except for a few cases, explicit bases for such modules are not known. In this paper, we construct explicit bases for type $A$ root systems. Our construction is based on Bandlow-Musiker's integral formula for a basis of the space of quasiinvariants. The integral formula can be considered as an expression for the inverse of the primitive derivation introduced by K. Saito. We prove that the discrete analogues of the integral formulas provide bases for Catalan and Shi arrangements.

description: Tropical secondary forests are widespread in the anthropogenically modified landscapes. Because tropical secondary forests were known to show a steady rate of above-ground biomass (AGB) recovery, they were expected to play a crucial role in carbon sequestration. However, in a preliminary survey of logged-over forests in Borneo, some patches covered with ferns and vines do not seem to recover steadily despite the fact that several decades have passed since the last logging. The presence and abundance of fern/vine thickets may affect the AGB recovery, but few studies have investigated the effects of the thickets. We established a total of seventeen 20-m radius circular plots in logged-over forests, Sabah, Malaysia, with a varying degree of fern/vine coverage, and tested the hypothesis that the greater fern/vine coverage would retard the AGB recovery. The net AGB accumulation rate from 2014 to 2019 was lower in the forests with a higher fern/vine coverage. Our lower bound of the accumulation rate was much lower than the previously reported rates elsewhere. The number of newly recruited and small-diameter trees was lower, and the mortality of remnant trees was higher with increasing fern/vine coverage. The growth rate of the extant pioneer trees, which are expected to significantly contribute to the initial build-up phase of the secondary succession, was inhibited when ferns and vines covered the canopy. Our study suggests that the secondary succession is arrested and the recoverability of forest stands is lower than formerly predicted when they are covered by thick ferns and vines.

description: Cosmic shear offers a remarkbly clean way to measure the equation of state of the Universe and its evolution. Resolution over a wide field is paramount, and Antarctica offers unique possibilities in this respect. There is an order of magnitude gain in speed over temperate sites, or a factor three in surface density. This means that PILOT outperforms much larger telescopes elsewhere, and can compete with the proposed DUNE space mission. Keywords: Antarctic astronomy, Surveys, Adaptive optics, Weak lensing
