description: The effect of geometry in the statistics of \textit{nonlinear} universality classes for interface growth has been widely investigated in recent years and it is well known to yield a split of them into subclasses. In this work, we investigate this for the \textit{linear} classes of Edwards-Wilkinson (EW) and of Mullins-Herring (MH) in one- and two-dimensions. From comparison of analytical results with extensive numerical simulations of several discrete models belonging to these classes, as well as numerical integrations of the growth equations on substrates of fixed size (flat geometry) or expanding linearly in time (radial geometry), we verify that the height distributions (HDs), the spatial and the temporal covariances are universal, but geometry-dependent. In fact, the HDs are always Gaussian and, when defined in terms of the so-called "KPZ ansatz" $[h \simeq v_{\infty} t + (Γt)^β χ]$, their probability density functions $P(χ)$ have mean null, so that all their cumulants are null, except by their variances, which assume different values in the flat and radial cases. The shape of the (rescaled) covariance curves is analyzed in detail and compared with some existing analytical results for them. Overall, these results demonstrate that the splitting of such university classes is quite general, being not restricted to the nonlinear ones.

description: We study the low-velocity (0.1--100 $μ$m.s$^{-1}$) frictional properties of interfaces between a rough glassy polymers and smooth silanized glass, a configuration which gives direct access to the rheology of the adhesive joints in which shear localizes. We show that these joints exhibit the full phenomenology expected for confined quasi 2D soft glasses: they strengthen logarithmically when aging at rest, and weaken (rejuvenate) when sliding. Rejuvenation is found to saturate at large velocities. Moreover, aging at rest is shown to be strongly accelerated when waiting under finite stress below the static threshold.

description: The African Growth and Opportunities Act (AGOA) which was signed into law in 2000 as part of U.S. trade legislation has the objectives of increasing trade and investment between the U.S. and eligible Sub-Saharan African (SSA) countries, by reducing or eliminating tariffs applied to African exports of different products. This Act represents a promising approach to economic growth and development in SSA through international trade. This research paper examines the impact of AGOA on African agricultural exports. The study uses the gravity trade model framework and panel data depicting annual agricultural trade from 35 eligible SSA countries to the United States over years both before and after AGOA’s implementation (1990-2011). There is wide variation in trade flows and the economic characteristics of the panel data obtained from the 35 SSA countries include numerous observations of zero trade flows. As the gravity equation is generally estimated in logarithms which are not defined for zero values, alternative statistical estimation methods, the Heckman model and the Poission family of regression modeling techniques, were used to test whether the inclusion of the zero values would change the parameter estimates significantly. The study differs from previous empirical analyses of AGOA which did not attempt to account for zero trade flows. In addition, most of these studies were based on data from the early years of AGOA while this study includes more recent data and is based on a longer time period. The statistical results indicate that the AGOA trade preferences do not have a statistically significant impact on SSA agricultural exports, although some of the model results indicate that AGOA may have a positive effect on SSA agricultural exports to the United States. Results from some of the models indicate that an increase in per capita GDP in the SSA countries decreases agricultural exports to the United States. Likewise, currency appreciation of the SSA countries decreases the agricultural trade flows. A tariff rate quota and the exclusion of some agricultural products from the legslation still limit AGOA’s broader positive economic impact. Further liberalization, reform and extension of AGOA for a longer time, investment to improve trade facilitation services, agricultural productivity and processing to meet high quality standards, and adoption of a comprehensive development assistance policy are needed if the African countries are to realize sustained economic growth and development.

description: The TexOx-1000 (TOOT) radio source redshift survey is designed to find and study typical radio-loud active galaxies to high redshift. They are typical in the same sense that L* galaxies are typical of galaxies in the optical. Previous surveys have only included the most luminous, rare objects at and beyond the peak of activity at z~2, but in going a factor of 100 fainter than the 3C survey, and in assembling a large sample, TOOT probes for the first time the objects that dominate the radio luminosity density of the universe at high redshift. Here we describe the current status of the TOOT survey and draw preliminary conclusions about the redshift distribution of the radio sources. So far, ~520 of the 1000 radio sources have redshifts, with ~440 of those in well-defined, complete, sub-regions of the survey. For these we find a median redshift of z=1, but the measured redshift distribution has a deficit of objects with z~2, when compared to predictions based on extrapolating luminosity functions constrained by higher-flux-density samples. These are the more luminous objects that usually show emission lines, and which should not be missed in the survey unless they are heavily reddened. The deficit may be real, but it would not be too surprising to find a population of faint, reddened radio sources at z~2-3 among the TOOT sources yet to have accurate redshifts.

description: The Ising model in small-world networks generated from two- and three-dimensional regular lattices has been studied. Monte Carlo simulations were carried out to characterize the ferromagnetic transition appearing in these systems. In the thermodynamic limit, the phase transition has a mean-field character for any finite value of the rewiring probability p, which measures the disorder strength of a given network. For small values of p, both the transition temperature and critical energy change with p as a power law. In the limit p -> 0, the heat capacity at the transition temperature diverges logarithmically in two-dimensional (2D) networks and as a power law in 3D.

description: Xylella fastidiosa is a Gram-negative bacterium causing devastating diseases of many plants, including important crops as grapevine, peach, citrus, almond, coffee and pear. In the last decade, X. fastidiosa has devastated olive heritage in Apulia region (Italy) inducing a severe disease called “Olive Quick Decline Syndrome” The disease also infected millennial olive plants. The bacterium was introduced in this region from abroad and rapidly spread causing heavy economical losses and cultural and social damages. The eradication of infected plants in the restricted area at beginning of infection could be an effective approach to eliminate the bacterium. Unfortunately, this method was too late and partially applied. Studies carried out successively demonstrated that a zinc-copper-citric acid bio-complex allowed a consistent reduction of the infection on olive trees. The use of synthetic bactericides was discouraged as their use could cause resistance in the host plants and because of the long term impact of residues in agricultural products with a risk to human and animal health. Thus, a valid alternative could be the use of natural antibacterial metabolites. Some year ago, radicinin, a pihydropyranopyran-4,5-dione, was proposed as natural pesticide to control the infection of X. fastidiosa causing grapevines (Vitis vinifera L.) Pierce’s disease. Recently, radicinin together with some analogues were isolated from Cochliobolus australiensis, a fungus proposed as mycoherbicide to control buffelgrass (Cenchrus chliaris) an invasive weed in North America. The fungal production of radicinin was very low and this prompted the development of an efficient and ecofriendly total synthesis that afforded in good yield its biosynthetic precursor 3-deoxyradicinin. Further studies showed that 3-deoxyradicin displays phytotoxic activity against buffelgrass and antibacterial activity against X. fastidiosa comparable with those of radicinin. These results allowed us propose both radicinin and 3-deoxyradicinin as potential natural pesticides which, conveniently bioformulated could be used to control of X. fastidiosa.

description: The optical spectra of CdSe nanocrystals up to 55 A in diameter are analyzed in a wide range of energies from the fine structure of the low-energy excitations to the so-called high-energy transitions. We apply a symmetry-based method in two steps. First we take the tight-binding (TB) parameters from the bulk sp^{3}s^{*} TB model, extended to include the spin-orbit interaction. The full single-particle spectra are obtained from an exact diagonalization by using a group-theoretical treatment. The electron-hole interaction is next introduced: Both the Coulomb (direct) and exchange terms are considered. The high-energy excitonic transitions are studied by computing the electric dipole transition probabilities between single-particle states, while the transition energies are obtained by taking into account the Coulomb interaction. The fine structure of the lowest excitonic states is analyzed by including the electron-hole exchange interaction and the wurtzite crystal-field terms in the exciton Hamiltonian. The latter is diagonalized in the single electron-hole pair excitation subspace of progressively increasing size until convergence. The peaks in the theoretical transition spectra are then used to deduce the resonant and nonresonant Stokes shifts, which are compared with their measured values in photoluminescence experiments. We find that the final results depend on the crystal-field term, the relative size of the surface and the degree of saturation of the dangling bonds. The results show a satisfactory agreement with the available experimental data.

description: Abstract

This study explores the impact of principals' leadership styles on teachers' performance in Mogadishu schools, Somalia. The research examines three key leadership styles—authoritative, democratic, and autocratic—and their influence on teachers' academic performance, job satisfaction, and overall effectiveness. Using a descriptive research design, data was collected through questionnaires from a sample of 80 participants, including teachers and school administrators. The findings indicate that authoritative leadership often results in structured guidance but limits teacher autonomy, while democratic leadership fosters collaboration and enhances teacher motivation. Conversely, autocratic leadership was found to negatively affect teachers' performance due to rigid control and lack of involvement in decision-making. The study concludes that adopting a balanced leadership approach, incorporating democratic principles with structured guidance, can significantly improve teacher performance and student outcomes. Recommendations include leadership training for principals, improved communication strategies, and policies that promote teacher engagement in school decision-making processes.

description: In this paper we set up, estimate and test a short-run model for the poultry sector in Greece. The model allows for the simultaneous existence of a monopolistically competitive and a competitive segment, and determines producer and consumer prices, and the quantity consumed. We provide evidence on steady-state parameters such as demand and supply elasticities, as well as on speeds of adjustment of prices and quantities. The evidence suggests that adjustment is very rapid, although quantities appear to be adjusting more quickly than prices. The model is used to examine the dynamics of adjustment to demand and supply-side disturbances.

description: Soils in a large part of Niger's agricultural area are sandy and very low in nitrogen (N), phosphorus (P) and organic matter. This low soil fertility combined with low and erratic rainfall constitutes a severe constraint on food cropping in the area. Although agronomists have advised chemical fertilization as a means of improving soil fertility, little fertilizer has been used in this area of the world. The economic management of soil fertility in the agricultural area of Niger is analyzed using a dynamic model of farmer decision-making under uncertainty. The model is based on agronomic principles of plant growth and accounts for the carry over of P, an immobile nutrient. At current input prices, a soil P content of at least 14 ppm is found to be desirable. This target is above the natural soil fertility level of about 3 ppm. It can be maintained with a moderate annual application (12 kg P20 5 ha- 1) of simple superphosphate. Results also suggests that returns to N fertilization are too low and variable to warrant the use of this input.

description: This paper develops a stochastic multi-period decision model to analyse a continuous wheat cropping system infested by wild oats (Avena fatua L.), in southern Australia. The multi-period solutions is obtained by employing a dynamic programming model in conjunction with a bioeconomic simulation model. An empirically estimated dose response function is used to derive the optimal herbicide rate. Uncertainties due to environmental effects on the performance of herbicide and crop yields are modelled and optimal decision rules derived. The results indicate that substantial economic gains can be realised if herbicide dose decisions are taken by considering future profit effects of current decisions, as opposed to the more common approach of only considering the current-period effect.

description: Since the start of ALMA observatory operation, new and important chemistry of infrared cold core was revealed. Molecular transitions at millimeter range are being used to identify and to characterize these sources. We have investigated the 231 GHz ALMA archive observations of the infrared dark cloud region C9, focusing on the brighter source that we called as IRDC-C9 Main. We report the existence of two sub-structures on the continuum map of this source: a compact bright spot with high chemistry diversity that we labelled as core, and a weaker and extended one, that we labelled as tail. In the core, we have identified lines of the molecules OCS(19-18), $^{13}$CS(5-4) and CH$_{3}$CH$_{2}$CN, several lines of CH$_{3}$CHO and the k-ladder emission of $^{13}$CH$_{3}$CN.We report two different temperature regions: while the rotation diagram of CH$_{3}$CHO indicates a temperature of 25 K, the rotation diagram of $^{13}$CH$_{3}$CN indicates a warmer phase at temperature of $\sim450$K. In the tail, only the OCS(19-18) and $^{13}$CS(5-4) lines were detected. We used the $Nautilus$ and the \textsc{Radex} codes to estimate the column densities and the abundances. The existence of hot gas in the core of IRDC-C9 Main suggests the presence of a protostar, which is not present in the tail.

description: Many systems respond to slowly changing external conditions with crackling noise, created by avalanches or pulses of a broad range of sizes. Examples range from Barkhausen Noise in magnets to earthquakes. Here we discuss how the scaling behavior of the avalanche size and duration distribution and the power spectra of this noise depend on the rate at which the external conditionsare changed. We derive an exponent inequality as a criteria for the relevance of adding a small driving rate to the adiabatic model. We use the zero temperature nonequilibrium random field Ising model to test our results, which are expected to be applicable to a large class of systems with crackling noise. They also agree with recent experiments on Barkhausen noise in various materials.

description: Recently several authors have proposed stochastic models of the growth of the Web graph that give rise to power-law distributions. These models are based on the notion of preferential attachment leading to the ``rich get richer'' phenomenon. However, these models fail to explain several distributions arising from empirical results, due to the fact that the predicted exponent is not consistent with the data. To address this problem, we extend the evolutionary model of the Web graph by including a non-preferential component, and we view the stochastic process in terms of an urn transfer model. By making this extension, we can now explain a wider variety of empirically discovered power-law distributions provided the exponent is greater than two. These include: the distribution of incoming links, the distribution of outgoing links, the distribution of pages in a Web site and the distribution of visitors to a Web site. A by-product of our results is a formal proof of the convergence of the standard stochastic model (first proposed by Simon).

description: The study examined the determinants of farmers’ access to microcredit from cooperative societies in Ondo state. A multistage sampling technique was used to obtain data from 100 respondents. Primary data was collected for the purpose of the study. We used descriptive statistics and logit regression model to analyses the data collected. Result showed that the farmers were mostly male farmers (64%) while majority of the farmers had a mean age of 44.10 ± 14.70. It was also revealed that consumer cooperative society, producer cooperative society, marketing cooperative society, cooperative farming society and credit and thrift cooperative society were the major forms of cooperative used by the farmers. The result also shows that age, marital status, farm size, farming experience, credit from another source and number of years in the cooperative significantly influenced farmers’ access to microcredit from cooperative society.

description: Social/community activities contribute to incidental physical activity, which may help prevent secondary stroke. This research aims to explore stroke survivor activity patterns, physical activity levels, and self-efficacy. An exploratory observational study in a cohort of community-dwelling stroke survivors was conducted. Data were collected with accelerometers, activity diaries, and the Self-Efficacy for Exercise Scale. Pre-specified categories were used to describe activity context. Pearson’s correlation and Kruskal–Wallis analyses were used to analyse physical activity relative to self-efficacy and time of day. Forty-seven stroke survivors were recruited (47% female, aged 76 years (IQR 65–83)). Most awake time (81%) was spent in the home. Structured exercise and community and/or social activities were efficient forms of activity and accounted for 17.7% and 23.2% of steps/day, and 2.5% and 14.1% of time, respectively. Participants were most active in the afternoon and morning compared with the evening (p = 0.005 and p = 0.045). Community ambulators had higher self-efficacy scores compared to household ambulators (p = 0.007). Stroke survivors can be active via structured exercise, as well as engaging in outdoor social and community activities. Those who reported higher levels of self-efficacy were more active. Health professionals should consider these factors when promoting physical activity during rehabilitation. Social and community activities are an efficient way for stroke survivors to accumulate physical activity; therefore, healthcare professionals should encourage return to these activities for secondary stroke prevention. Because self-efficacy is positively associated with physical activity levels, healthcare professionals need to assess and develop self-efficacy when aiming to increase physical activity levels in stroke survivors. When prescribing physical activity, health professionals should consider that stroke survivors are more likely to be active in the morning and afternoon compared to the evening.

description: This report empirically examines the role which capital accumulation plays in the growth of agricultural production potential. The report assumes that the degree to which available technology can be implemented in a nation's agricultural sector depends on accumulated investments that have been made in the sector. Results from estimating aggregate agricultural production functions show the primary importance of rural labor in accounting for agricultural GDP and crop production. Capital accumulation is the dominant explainer of livestock production. Estimation results support the conjecture that capital tends to save scarce land resources (substitute relationship) and use rural labor (complementarity relationship). Output supply elasticities derived from the estimated equations tend to be large. The large elasticities imply that price distortions have had large impacts on resource use and production.

description: Genus Alvania Risso, 1826
 Type species. Alvania europea Risso, 1826, subsequent designation by Nevill, 1885 (5 Alvania cimex (Linne´, 1758)).
 The genus Alvania is here taken in a very broad sense, as a catchall genus for species of Rissoidae having both spiral and axial sculpture on the shell, until some phylogeny is unravelled. This is a difficult task in this speciose group, and requires a broader geographic scope. Most characters currently considered for species definition are highly liable to convergence.

description: Observations of two unclassified Low Mass X-ray Binaries, X1543-624 and X1556-605, are presented. In the 2-10 keV band the first of the two sources is a factor two stronger than the other. Both sources do not show X-ray bursts, dips or eclipses in their X-ray light curves. We find that both spectra are described by a two-component model consisting of emission from a cool accretion disk plus a Comptonized blackbody with kTbb ~ 1.5 keV in a low opacity plasma. The spectrum of X1543-624 hardens from the first to the second observation, when the source slowly moves from right to left in the colour-colour diagram. The spectrum of X1556-605 can also be described by a model consisting of a blackbody plus an unsaturated Comptonization with electron energy kTe ~ 4 keV. In the first observation, X1543-624 shows evidence of a Fe K emission line at 6.4 keV. Moreover in both observations, the source spectrum exhibits an emission feature around 0.7 keV, which is interpreted as due to the superposition of the K edge absorption features of O and Ne elements with uncommon relative abundances with respect to the solar one (O/O(sun) ~0.3, Ne/Ne(sun) ~ 2.5). In the spectrum of X1556-605 no emission lines are observed. We discuss these results and their implications on the source classification and the accretion geometry on the compact object.

Reentrant superconductivity in a strong applied field within the tight-binding model

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: It was suggested by Rasolt and Tešanović that the Landau level quantization in isotropic superconductors could enhance superconductivity in a very strong magnetic field, above the upper critical field ($H_{c2}$). We derive a generalized Harper equation for superconducting systems, and show that a similar reentrant behavior appears in a lattice model, even though the Landau--level--structure is destroyed by the periodic potential in that case. Both the orbital and the Zeeman field--induced effects are taken into account.

description: A stated objective of the Ethiopian Government since it came to power in 1975 has been to increase the production of crops for both domestic consumption and export. Consequently, a number of plans and programs have been proposed and implemented to bring about such development in Ethiopian agriculture. This paper mainly focuses 011 a macro review of the general course of Ethiopian agricultural development since the land reform of 1975. The food production in Ethiopia has lagged behind the population growth as evidenced by the gap between the growth rates of population (3%) and food production (1.8%) over the period from 1970 to 1983. Recently, this situation has, perhaps, further deteriorated. Seventy-one percent of the total land mass is estimated to be suitable for agriculture, but only about 19% is cultivated. This suggests an underutilisation of land. Moreover, Ethiopia has a persistent subsistence production problem in agriculture. Agricultural research and education which are essential to development have not been given due attention by the policy makers. As a result, the agricultural technologies used by farmers have changed little in this century. Moreover, small-scale farmers, although still the most potent economic force in the country, have not been given the incentives necessary to expand production, and currently receive less than adequate support from the central government. Some 85%, 50%, and 79% of total agricultural credit, fertiliser and improved seeds respectively go directly to socialist enterprises (state farms and producers' cooperatives) which, up to 1985, have jointly accounted for only 5% of the total cultivated land and 4% of the national crop production. The favouring of large-scale and capital-intensive state-owned farming enterprises with credit, subsidies, and fiscal incentives, while neglecting smallholders, has contributed to the stagnation of agricultural production in Ethiopia. Overall, the analysis indicates that there has been no significant development of agriculture in Ethiopia following the 1975 land reform.

description: Spatial fluctuations of the effective pairing interaction between electrons in a superconductor induce variations of the order parameter which in turn lead to significant changes in the density of states. In addition to an overall reduction of the quasi-particle energy gap, theory suggests that mesoscopic fluctuations of the impurity potential induce localised tail states below the mean-field gap edge. Using a field theoretic approach, we elucidate the nature of the states in the `sub-gap' region. Specifically, we show that these states are associated with replica symmetry broken instanton solutions of the mean-field equations.
