description: Slides accompanying one hour webinar run by Energy Systems Catapult (ESC) based in Birmingham, United Kingdom: https://es.catapult.org.uk The main theme concerns the legal context of energy sector datasets — principally from the perspective of European and United Kingdom law — and the use of open licenses to enable maximum use and re‑use. Abstract Suitably licensed open data together with relevant open standards can contribute to better public policy for the much needed energy transition, through more open science and improved public interest analysis. This talk covers the legal context for such data, the role of public licensing, the role of open standards, the need for a collective agreement on semantics and metadata in particular, and benefits of community curation. The talk is limited to non‑personal data that may be made public legitimately, thereby avoiding matters of personal and commercial privacy.

description: We investigate competitiveness and price behaviour in the Israeli citrus export sector following the removal of the government export monopoly and the entry of private export companies in 1991. We identify asymmetric price transmission for some exporters even in the liberalized market which only became symmetric when a minimum price agreement was established by the government in the grapefruit market. Our findings indicate that citrus growers’ seasonal losses resulting from asymmetric price transmission amounted to as much as 4.0% of their total revenues, and a much larger share of their profits. This result is consistent with the hypothesis that the observed asymmetry in price transmission was caused by Israeli exporters exerting market power over Israeli citrus growers. Concluding, our analysis demonstrates that the liberalization of the Israeli grapefruit export market by the abolishment of the government marketing board alone was not sufficient to establish a competitive market. Rather, an additional temporary government market intervention was necessary to foster competitive pricing behaviour by the exporting companies vis-à-vis the Israeli grapefruit growers.
New results on source and diffusion spectral features of Galactic cosmic rays: I- B/C ratio

description: In a previous study (Maurin et al., 2001), we explored the set of parameters describing diffusive propagation of cosmic rays (galactic convection, reacceleration, halo thickness, spectral index and normalization of the diffusion coefficient), and we identified those giving a good fit to the measured B/C ratio. This study is now extended to take into account a sixth free parameter, namely the spectral index of sources. We use an updated version of our code where the reacceleration term comes from standard minimal reacceleration models. The goal of this paper is to present a general view of the evolution of the goodness of fit to B/C data with the propagation parameters. In particular, we find that, unlike the well accepted picture, and in accordance with our previous study, a Kolmogorov-like power spectrum for diffusion is strongly disfavored. Rather, the $χ^2$ analysis points towards $δ\gtrsim 0.7$ along with source spectra index $\lesssim 2.0$. Two distinct energy dependences are used for the source spectra: the usual power-law in rigidity and a law modified at low energy, the second choice being only slightly preferred. We also show that the results are not much affected by a different choice for the diffusion scheme. Finally, we compare our findings to recent works, using other propagation models. This study will be further refined in a companion paper, focusing on the fluxes of cosmic ray nuclei.

description: This paper quantitatively assesses the effect of value chain development projects on market linkages of small-scale farmers of a staple crop and agricultural income. We focus on Nicaraguan bean producers participating in a value chain development project. Using a panel data set, we apply difference-in-differences and instrumental variables estimators to identify causal effects of programme participation. We first quantify the positive direct effect of training on bean sales in terms of quantity and percentage of beans sold in linked markets. Second, we show that intensified commercialisation contributes to total agricultural income, suggesting a positive indirect effect of the intervention. Our results indicate that market linkage of smallholder farmers requires different sets of intervention tools than farm technical assistance.

description: Elastic materials with holes and inclusions are important in a large variety of contexts ranging from construction material to biological membranes. More recently, they have also been exploited in mechanical metamaterials, where the geometry of highly deformable structures is responsible for their unusual properties, such as negative Poisson's ratio, mechanical cloaking, and tunable phononic band gaps. Understanding how such structures deform in response to applied external loads is thus crucial for designing novel mechanical metamaterials. Here we present a method for predicting the linear response of infinite 2D solid structures with circular holes and inclusions by employing analogies with electrostatics. Just like an external electric field induces polarization (dipoles, quadrupoles and other multipoles) of conductive and dielectric objects, external stress induces elastic multipoles inside holes and inclusions. Stresses generated by these induced elastic multipoles then lead to interactions between holes and inclusions, which induce additional polarization and thus additional deformation of holes and inclusions. We present a method that expands the induced polarization in a series of elastic multipoles, which systematically takes into account the interactions of inclusions and holes with the external stress field and also between them. The results of our method show good agreement with both linear finite element simulations and experiments.

We find a bifurcation phenomenon in temperature dependence of relaxation constants, which is never observed in the weak-coupling regime. We also discuss inequalities among the relaxation constants in our model and show the well-known relation 2Γ_T >= Γ_L, for example, for a wider parameter region than before.

description: An adequate representation of the technological trend component of yield time series is of crucial importance for the successful design of risk management instruments. However, for many transition and developing countries, the estimation of the technological trend is complicated by the joint occurrence of three phenomena: (i) a high level of heterogeneity among different farms in a region; (ii) non-linear development of technological change; and (iii) high yield variations as a consequence of high exposure of rainfed agriculture to extreme weather events. Under these situations, the usually applied approach to detrend crop yield data using Ordinary Least Squares is known to be biased. Based on a unique data set of 47 farm yield data from northern Kazakhstan, we evaluated different alternative approaches. First, we consider the use of the MM-estimator, a robust regression technique for detrending. Second, we evaluate the effect of adding information on extreme climate events as an additional regressor. Finally, we consider combinations of the two former approaches and compare the implications of the different aggregation level on trend estimations. The results reveal the importance of using single farm yield data for detrending, because technical trends in Kazakh wheat yields are highly farm-specific. Furthermore, our analysis shows that the estimation of technological trends can be improved by incorporating weather information in the regression model if time series of crop yield data contain severe fluctuations due to occurrence of climatic extreme events. Thus, the presented analysis contributes to an improved crop yield analysis for many developing and transition countries facing similar conditions.
On the reliability of peak-flux distributions, with an application to solar flares

description: Narrow-band radio spikes have been recorded during a solar flare with unprecedented resolution. This unique example allows to study the effect of low resolution in previously published peak-flux distributions of radio spikes. We give a general, analytical expression for how an actual peak-flux distribution is changed in shape if the peaks are determined with low temporal and/or frequency resolution. It turns out that, generally, low resolution tends to cause an exponential behavior at large flux values if the actual distribution is of power-law shape. The distribution may be severely altered if the burst-duration depends on the peak-flux. The derived expression is applicable also to peak-flux distributions derived at other wavelengths (e.g. soft and hard X-rays, EUV). We show that for the analyzed spike-event the resolution was sufficient for a reliable peak flux distribution. It can be fitted by generalized power-laws or by an exponential.

Expression and Function of Galanin in Colonic Sensory Neurones

description: The gastrointestinal (GI) tract is innervated by both the enteric nervous system and the sensory nervous system, and it is the latter that is responsible for giving rise to conscious sensations arising from the GI tract, such as pain. In particular, the distal colon is a key source of visceral pain in both inflammatory bowel disease (e.g. ulcerative colitis and Crohn’s disease) and irritable bowel syndrome. In both conditions, pain relief is complicated by the GI side effects of commonly prescribed analgesics, such as non-steroidal anti-inflammatory drugs and opioids. Therefore, furthering knowledge about how sensory innervation of the GI tract is modulated in health and disease has the potential to identify new therapeutic avenues. Galanin is a neuropeptide that has various functions within the central and peripheral nervous systems, e.g. regulation of feeding and modulation of nociceptive pathways respectively. Galanin has been previously demonstrated to modulate the mechanosensitivity of vagal sensory afferents innervating the upper GI tract, but nothing is known about its role in the distal colon, i.e. the lower GI tract. Using mice, I therefore aimed to determine if galanin also modulates the lumbar splanchnic nerve (LSN), which innervates the distal colon, in both healthy and inflamed (hypersensitive) conditions. Using ex vivo LSN electrophysiological recordings I found that galanin dose-dependently inhibits LSN responses to mechanical stimuli and the mechanical hypersensitivity induced by acutely applied inflammatory mediators. Using galanin receptor agonists (GalR1: M671, GalR2: spexin), I identified that GalR1 mediates the inhibitory effects on LSN mechanosensitivity. Using a mouse model of colitis, I found that the LSN was hypersensitive to mechanical stimuli, but that galanin no longer produced any inhibitory effect. Immunohistochemistry experiments using thoracolumbar (T13-L1) and lumbosacral (L6-S1) dorsal root ganglia (DRG) retrograde labelled from the colon demonstrated that galanin is primarily expressed by putative nociceptors, but that no major expression changes occur during colitis. In summary, I have demonstrated that galanin inhibits LSN mechanosensitivity and inflammatory mediators induced mechanohypersensitivity, but that this inhibition is lost in an in vivo model. This work highlights the potential for targeting the galaninergic system to treat GI pain.

description: Recently Flach et.al. used a symmetry analysis to predict the appearance of directed energy current in homogeneously spatially extended systems coupled to a heat bath in the presence of an external ac field E(t). The systems are described by nonlinear field equations. Their symmetry analysis allowed them to make the right choice of E(t) so as to obtain symmetry breaking which causes directed energy transport for systems with a nonzero topological charge. Their numerical simulations verified the existence of the directed energy current. We use a rigorous collective variable for nonlinear Klein-Gordon equations to prove the rectification of the current is due to the excitation of an internal mode, $Γ(t)$, which describes the oscillation of the slope of the kink. The internal mode $Γ(t)$ is excited by its interaction with the center of mass of the kink, X(t), which is accelerated by E(t). The external field E(t) also causes the kink to be dressed, which affects the shape of the kink and modulates the interaction of $Γ(t)$ with X(t). However, we show that the dressing in the absence of excitation of the internal mode $Γ(t)$ cannot cause a directed energy current. We derive the expressions for the dressing and numerically solve the equations of motion for $Γ(t)$, X(t), and the momentum, P(t), which enable us to obtain the explicit expressions for the directed energy current and the ac driven kink profile. We then show the directed energy current vanishes unless the slope $Γ(t)$ is a dynamical variable.

description: This paper describes the participation of smallholders in commercial horticultural farming in Kenya and identifies constraints and critical factors that influence their decision to participate in this industry by selling their produce. The study employs panel survey data on smallholder producers of both international (export) and domestic market vegetables and controls for unobserved heterogeneity across farmers. We find that participation of smallholders in both the domestic and export vegetable markets declined and that this trend is associated with weather risks, high costs of inputs and unskilled labour, and erratic vegetable prices, especially in the international market. Different factors are at play in determining a household’s market choice for the commercialisation of vegetables: credit is important only when vegetables are (also) exported, livestock ownership is negatively related to production for the domestic market, and distance to the nearest market town positively related to all pathways of commercialisation, for example.

description: Rapid and homogeneous precipitation of nano-sized Si particles with high density was achieved in Al–1%Si alloy by electric pulses treatment (EPT) in a liquid nitrogen bath (∼77 K). In contrast, when processed by EPT in air or by high-temperature (527–720 K) salt bath treatment, the precipitate density decreases dramatically. The homogeneous precipitation of Si could be facilitated by both the low-temperature environment and the non-thermal effects of EPT. The low-temperature environment provides a high driving force for nucleation, and retains the quenched-in vacancies serving as potential nucleation sites. The non-thermal effects of EPT can significantly promote local migration of solutes and vacancies at such low temperatures.

description: We address the problem of the origin of massive stars, namely the origin, path and timescale of the mass flows that create them. Based on extensive numerical simulations, we propose a scenario where massive stars are assembled by large-scale, converging, inertial flows that naturally occur in supersonic turbulence. We refer to this scenario of massive-star formation as the "Inertial-Inflow Model". This model stems directly from the idea that the mass distribution of stars is primarily the result of turbulent fragmentation. Under this hypothesis, the statistical properties of the turbulence determine the formation timescale and mass of prestellar cores, posing definite constraints on the formation mechanism of massive stars. We quantify such constraints by the analysis of a simulation of supernova-driven turbulence in a 250-pc region of the interstellar medium, describing the formation of hundreds of massive stars over a time of approximately 30 Myr. Due to the large size of our statistical sample, we can say with full confidence that massive stars in general do not form from the collapse of massive cores, nor from competitive accretion, as both models are incompatible with the numerical results. We also compute synthetic continuum observables in Herschel and ALMA bands. We find that, depending on the distance of the observed regions, estimates of core mass based on commonly-used methods may exceed the actual core masses by up to two orders of magnitude, and that there is essentially no correlation between estimated and real core masses.

description: The result by Burnett-Kroll (BK) states that for radiative decays the interference of ${\cal O}(ω^{-1})$ in the photon energy $ω$, vanishes after sum over polarizations of the involved particles. Using radiative decays of vector mesons we show that if the vector meson is polarized the ${\cal O}(ω^{-1})$ terms are null only for the canonical value of the magnetic dipole moment of the vector meson, namely ${\bf g}=2$ in Bohr's magneton units. A subtle cancellation of all ${\cal O}(ω^{-1})$ terms happens when summing over all polarizations to recover the Burnett-Kroll result. We also show the source of these terms and the corresponding cancellation for the unpolarized case and exhibit a global structure that can make them individually vanish in a particular kinematical region.

description: We perform two- and three-dimensional particle-in-cell simulations of reconnection in magnetically-dominated pair plasmas subject to strong Compton cooling. Reconnection under such conditions operates in accretion disk coronae around black holes, which produce hard X-rays through Comptonization. Our simulations show that most of the plasma in the reconnection layer is kept cold by Compton losses and locked in magnetically-dominated plasmoids with small thermal pressure. Compton drag clears cavities inside plasmoids and affects their bulk motions. These effects, however, weakly change the reconnection rate and the plasmoid size distribution from those in non-radiative reconnection. This demonstrates that the reconnection dynamics is governed by similar magnetic stresses in both cases and weakly affected by thermal pressure. We examine the energy distribution of particles energized by radiative reconnection and observe two components. (1) A mildly-relativistic peak, which results from bulk motions of cooled plasmoids. This component receives most of the dissipated reconnection power and dominates the output X-ray emission. The peak has a quasi-Maxwellian shape with an effective temperature of 100 keV. Thus, it mimics thermal Comptonization used previously to fit hard-state spectra of accreting black holes. (2) A high-energy tail, which receives 20% of dissipated reconnection power. It is populated by particles accelerated impulsively at X-points or "picked up" by fast outflows from X-points. The high-energy particles immediately cool, and their inverse Compton emission explains the MeV spectral tail detected in the hard state of Cyg X-1. Our first-principle simulations support reconnection as a mechanism powering hard X-ray emission from accreting black holes.

description: Using the 2009 data of the China Health and Nutrition Survey from Guizhou province, this paper analyzes whether an official ethnic label can be linked to a lower probability of non-agricultural employment. Results suggest that the Buyi and the Miao are less likely to work in non-agricultural fields than are Han (the majority group); the Tujia are more likely to work in non-agricultural fields than are Han. The predicted probability of non-agricultural employment for the Miao is lower than that of Han at almost all educational and age levels. Alongside the official ethnic label, more years of education and younger age appear to be most crucial for working in non-agricultural employment.

In such situations however, sulphur and sodium chloride, contained in the coal, are known to form sodium sulphate that, if deposited at the root of the single crystal turbine blades, can initiate hot corrosion. Low temperature Type II corrosion consists of the formation of a fused salt melt, which interacts with the combustion gases and causes other constituents of the alloy to dissolve. The resulting melt prevents the oxide to be protective. Simultaneously, the large centrifugal stresses in the blade attachment area can cause the substrate to crack. If undetected, such cracks will grow and result in catastrophic failure. The current work consisted in the construction and commissioning of a customised test bench reproducing the environments experienced at the root of the turbine blades. The investigation compared a first-generation Ni-based superalloy with 12.2 wt% Cr (SCRY-83) commonly referred to as “Cr2O3-former” in regard to its oxide composition, to a second generation one with 6.5 wt% Cr (SCRY-4) also referred to as “Al2O3-former”. A mixture of NaCl and Na2SO4 is often used in the literature to reproduce hot corrosion. The effect of each deposits was first analysed independently. It was found that NaCl caused scale damage, via the formation of high vapor pressure compounds for the Al2O3-former, or via the transport of Cr to the gas interface for the SCRY-83. In contrast, Na2SO4 formed a liquid phase at the surface of both alloys, but initiated damage only when in contact with the Al2O3-former. Sulphur ingress was the largest on sample coated with NaCl and exposed to a mixture of air and SO2/SO3, affecting particularly the Al2O3-former. The simultaneous application of force in these environments always resulted in a larger reaction layer, and was thought to originate from the flow of liquid phases (NaCl-NiCl2 when coated with NaCl, or Ni3S2 when exposed to air+SO2/SO3, or Na2SO4-NiSO4 when coated with NaCl and exposed to air+SO2/SO3). The type II environment with applied force was the most aggressive and it initiated two cracks on the Al2O3-former, and a 40 µm thick damaged region was detected on the Cr2O3-former. Proven and novel methods of damage characterisation were assessed throughout this work, and their suitability was found to depend on the harshness of the environment. The high Cr alloy always outperform the Al2O3-former or exhibited similar depth of attack (when coated with NaCl).

description: We investigate the effect of lattice disorder and local correlation effects in finite and periodic silicene structures caused by carbon doping using first-principles calculations. For both finite and periodic silicene structures, the electronic properties carbon-doped monolayers are dramatically changed by controlling the doping sites in the structures, which is related to the amount of disorder introduced in the lattice and electron-electron correlation effects. By changing the position of the carbon dopants, we found that a Mott-Anderson transition is achieved. Moreover, the band gap is determined by the level of lattice disorder and electronic correlation effects. Finally, these structures are ferromagnetic even under disorder which has potential applications in Si-based nanoelectronics, such as field-effect transistors (FETs).

description: This research was carried out to provide empirical information on the relationship between agricultural production and the growth of Nigerian economy with focus on poverty reduction. Time series data were employed in this research and the analyses of the data were done using unit root tests and the bounds (ARDL) testing approach to cointegration. The result of the data analysis indicated that agricultural production was significant in influencing the favourable trend of economic growth in Nigeria. Despite the growth of the Nigerian economy, poverty is still on the increase and this calls for a shift from monolithic oil-based economy to a more plural one with agriculture being the lead sector. It was recommended that pro poor policies should be designed for alleviating rural poverty through increased investments in agricultural development by the public and private sector.

description: 26. Anetia Robineau-Desvoidy, 1863a: 868.
 ORIGINALLY INCLUDED SPECIES: Anetia occlusa Robineau-Desvoidy, 1863.
 TYPE SPECIES: Anetia occlusa Robineau-Desvoidy, 1863, by original designation.
CURRENT STATUS: Preoccupied by Hübner, 1823; no new replacement name proposed; placed in “Doubtful taxa in Tachinidae ” by Herting & Dely-Draskovits (1993: 435).
FAMILY: TACHINIDAE.
 REMARKS: Sabrosky & Arnaud (1965: 1103) placed Anetia in synonymy with Lydella Robineau-Desvoidy, 1830 and treated its type species (Anetia occlusa Robineau-Desvoidy, 1863) as a junior synonym of Lydella grisescens Robineau-Desvoidy, 1830, the type species of Lydella. Herting (1974, 1984) did not treat it; but Herting & Dely-Draskovits (1993), no doubt because of the absence of a type specimen of the type species, reasoned that no conclusive placement could be made and relegated it to “Doubtful taxa in Tachinidae ”.

't Hooft-Polyakov monopole and instanton-like topological solution in gauge-Higgs unification

description: We consider 't Hooft-Polyakov monopole (TPM) as a topological soliton in the 5-dimensional (5D) theory of gauge-Higgs unification. This scenario provides a very natural framework to incorporate the TPM, since the adjoint scalar is builtin as the extra-space component of higher dimensional gauge field. In the process of the analysis, we realize that the condition to be satisfied by the Bogomolny-Prasad-Sommerfield (BPS) state of TPM, the BPS monopole, is equivalent to an (anti-)self-dual condition for the higher dimensional gauge field. This observation, in turn, suggests the presence of instanton-like topological soliton living in the 4D space (including the extra dimension), instead of the 4D space-time in the case of ordinary instanton, say "space-like instanton" with finite energy, instead of finite action. We construct the field configuration for the space-like instanton and calculate its mass, handled by the compactification scale. Next we discuss the BPS monopole, as an anti-self-dual gauge field. We start by constructing a hedgehog-type solution as what is obtained by a local gauge transformation from a trivial vacuum. We also argue in some detail that the relation between these two types of topological solitons becomes manifest through the unified description by use of the ansatz adopted by 't Hooft.

Entanglement transfer from continuous variables to qubits

description: We show that two qubits can be entangled by local interactions with an entangled two-mode continuous variable state. This is illustrated by the evolution of two two-level atoms interacting with a two-mode squeezed state. Two modes of the squeezed field are injected respectively into two spatially separate cavities and the atoms are then sent into the cavities to resonantly interact with the cavity field. We find that the atoms may be entangled even by a two-mode squeezed state which has been decohered while penetrating into the cavity.

description: Pull-Pull (PPT) and Imazapyr resistant maize (IR) technologies are among the Striga weeds eradication innovations that have been promoted in western Kenya. In order to direct agricultural investment optimally, the most promising technology need to be identified and up scaled given limited financial and resource allocation trade-offs. Using data from a sample of 326 farmers, we applied the Average Treatment Effect (ATE) framework to estimate the actual and potential adoption rates of the two technologies. The results indicate relatively similar actual adoption rates of PPT (37%) and IR maize technology (36.3%). However, the potential adoption rates of PPT and IR maize technology were 56.3% and 46%, respectively, whereby the adoption gap of PPT (20%) was higher compared to that of IR maize technology (9%). These findings show that, if extra efforts are made to close the adoption gap to potential, PPT is a more attractive Striga control strategy.
