description: Some small-holders are able to generate reliable and substantial income flows through small-scale dairy production for the local market; for others, a set of unique transaction costs hinders participation. Cooperative selling institutions are potential catalysts for mitigating these costs, stimulating entry into the market, and promoting growth in rural communities. Trends in cooperative organization in east-African dairy are evaluated. Empirical work focuses on alternative techniques for effecting participation among a representative sample of peri-urban milk producers in the Ethiopian highlands. The variables considered are a modern production practice (cross-bred cow use), a traditional production practice (indigenous-cow use), three intellectual-capital-forming variables (experience, education, and extension), and the provision of infrastructure (as measured by time to transport milk to market). A Tobit analysis of marketable surplus generates precise estimates of non-participants' 'distances' to market and their reservation levels of the covariates -measures of the inputs necessary to sustain and enhance the market. Policy implications focus on the availability of cross-bred stock and the level of market infrastructure, both of which have marked effects on participation, the velocity of transactions in the local community and, inevitably, the social returns to agroindustrialization. © 2000 Elsevier Science B.V.

description: In this work we present the explicit calculation of Probability Distribution Function for a model system of granular gas within the framework of Tsallis Non-Extensive Statistical Mechanics, using the stochastic approach by Beck [C. Beck, Phys. Rev. Lett. 87, 180601 (2001)], further generalized by Sattin and Salasnich [F. Sattin and L. Salasnich, Phys. Rev. E 65, 035106(R) (2002)]. The calculation is self-consistent in that the form of Probability Distribution Function is not given as an ansatz but is shown to necessarily arise from the known microscopic dynamics of the system.

description: Recently, the Carnegie Mellon University Libraries began to implement a new strategic plan, which greatly increased the number, complexity, and scope of new projects and services sponsored by the Libraries. Historically, initiation, planning, and management of projects and services within Libraries lacked both codified processes and uniform management tools. Libraries’ leadership quickly realized that the rapid increase in the size of the unit's project and service footprints had rendered such an unstructured approach to project and service management untenable. In response to leadership's concerns, the Libraries’ Digital Strategy team launched an effort to establish a structure of governance around project and service management within the University Libraries. This paper will review the selection process for new project and service portfolio management tools, as well as the effort to define project initiation and management and service transition guidelines, with the intent of providing a framework for establishing project and service management governance in similar organizations.

description: To systematically summarize the research trends and emphases of ROP in the past decades by analyzing the characteristics of the top 100 cited ROP articles. The 100 most cited articles on ROP published from January 1, 1950 to December 31, 2021 were searched by Web of Science. Information such as year of publication, number of citations, journal and impact factor, type of research and topic, country of origin, institution and authorship of each article was extracted to analyze its characteristics. A total of 15,928 articles were returned. These articles were published in 43 journals between 1952 and 2018, originating from 14 countries. The most widely published journal was Pediatrics (n = 19, IF = 8.109), followed by Archives of Ophthalmology (n = 15, IF = 4.399). The most cited paper (Gole et al. Archives of Ophthalmology 2005 Jul, 1614 citations) reported on the international classification of ROP. The most prevalent topic was the pathophysiology of ROP (n = 39), followed by the treatment of ROP (n = 32). Most were original research (n = 72), mainly based on research design of basic science. The most published articles were published in the United States (n = 61), and the institutions were Oregon Health & Science University, Dept Ophthalmol (n = 7). These 100 most frequently cited papers reflect the significant progress and several hot topics of ROP in recent decades, and this paper will help us further understand the knowledge and progress of ROP diagnosis and treatment.

description: Nature might be kinder than previously thought as far as epsilon'/epsilon is concerned. We show that the recently obtained experimental value for epsilon'/epsilon does not require sizeable 1/N and isospin-breaking corrections. We propose to display the theoretical results for epsilon'/epsilon in a (P^{1/2}, P^{3/2}) plane in which the experimental result is represented by a (epsilon'/epsilon)_exp-path. This should allow to exhibit transparently the role of 1/N and isospin-breaking corrections in different calculations of epsilon'/epsilon. From now on theorists are allowed to walk only along this (epsilon'/epsilon)_exp-path.

description: We study gravitational waves from a hierarchical three-body system up to first-order postNewtonian approximation. Under certain conditions, the existence of a nearby third body can cause periodic exchange between eccentricity of an inner binary and relative inclination, known as Kozai-Lidov oscillations. We analyze features of the waveform from the inner binary system undergoing such oscillations. We find that variation caused due to the tertiary companion can be observed in the gravitational waveforms and energy spectra, which should be compared with those from isolated binaries and coplanar three-body system. The detections from future space interferometers will make possible the investigation of the gravitational wave spectrum in mHz range and may fetch signals by sources addressed.

description: A survey of two rural markets in southwest Nigeria over 14 months showed that supplies, sales and prices of sheep and goats varied widely during the period with a sharp peak during the Muslim festival of Eid-el-Kabir and a smaller peak during the Christmas-New Year period. Local West African Dwarf (WAD) sheep and goats and northern Y’ankasa sheep and Red Sokoto goats were traded in the markets and animals were purchased for rearing, ceremonies, butchering/catering, sacrifice, and festivals. There were significant differences between species/breeds purchased for various purposes. A hedonic prices model was fitted to determine factors influencing price. After adjustments were made for age, weight, sex, time of transaction and market, WAD sheep commanded higher prices than WAD goats and Red Sokoto goats for all purposes except for butchering/catering; Red Sokoto goats commanded similar or lower prices than WAD goats depending on the purpose for purchase; and Y’ankasa sheep, principally purchased for the Eid-el-Kabir festival, commanded marginally higher prices than WAD sheep. The market share of WAD sheep is currently small and is under competition from northern sheep and goats, so increased production of WAD sheep in the south will benefit both producers and consumers in the area. In general, the results indicate that buyers have preferences for specific breeds and species for specific purposes, so producers and sellers may benefit by targeting specific buyer categories and times of the year
Strain effects at solid surfaces near the melting point

Year: 2002
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: We investigate the effects of strain on a crystal surface close to the bulk melting temperature T_m, where surface melting usually sets in. Strain lowers the bulk melting point, so that at a fixed temperature below but close to T_m the thickness of the quasi-liquid film is expected to grow with strain, irrespective of sign. In addition, a strain-induced solid surface free energy increase/decrease takes place, favoring/disfavoring surface melting depending on the sign of strain relative to surface stress. In the latter case one can produce a strain-induced prewetting transition, where for increasing temperature the liquid film suddenly jumps from zero to a finite thickness. This phenomenology is illustrated by a realistic molecular dynamics simulation of strained Al(110).

Negative longitudinal magnetoconductance at weak fields in Weyl semimetals

description: Weyl semimetals are topological materials that provide a condensed-matter realization of the chiral anomaly. A positive longitudinal magnetoconductance quadratic in magnetic field has been promoted as a diagnostic for this anomaly. By solving the Boltzmann equation analytically, we show that the magnetoconductance can become negative in the experimentally relevant semiclassical regime of weak magnetic fields. This effect is due to the simultaneous presence of the Berry phase and the orbital magnetic moment of carriers and occurs for sufficiently strong intervalley scattering.

description: Anaplastic lymphoma kinases (ALK) tyrosine kinase inhibitors (TKIs) are effective and safe targeted therapies used in advanced ALK-positive non-small cell lung cancers (NSCLC). However, ALK-TKIs associated cardiovascular toxicities in patients with ALK-positive NSCLCremain incompletely characterized. We conducted the first meta-analysis to investigate this. To determine the cardiovascular toxicities associated with these agents, we carried out a meta-analysis comparing ALK-TKIs with chemotherapy and a meta-analysis comparing crizotinib with other ALK-TKIs. Statistical analysis was conducted to calculate the RRs and 95% confidence intervals (CIs) by using either random effects or fixed-effect models according to the heterogeneity of the included studies. A total of 11 studies (2855 patients) were included. ALK-TKIs ranked to have more severe cardiovascular toxicities than chemotherapy (RR 5.03, 95% CI 1.97–12.84, P = 0.0007) . Compared with other ALK-TKIs, increased risks of cardiac disorders and VTEs associated with crizotinib were found (cardiac disorders RR 1.75, 95% CI 1.07–2.86, P = 0.03; risk of VTEs RR 3.97, 95% CI 1.69–9.31, P = 0.002; respectively). ALK-TKIs were associated with higher risks of cardiovascular toxicities. Special attention should be given to the risks of cardiac disorders and VTEs related to crizotinib therapy.
On the direct detection of extragalactic WIMPs

description: We consider the direct detection of WIMPs reaching the Earth from outside the Milky Way. If these WIMPs form a distinct population they will, although of much lower flux than typical galactic halo WIMPs, have a number of features which might aid in their ultimate detectability: a high and essentially unique velocity ($\sim 600$ km/s in the galactic rest frame) due to their acceleration in entering the Milky Way, and most likely one or two unique flight directions at the Earth. This high velocity may be experimentally advantageous in direct detection experiments, since it gives a recoil signal at relatively high energy where background is generally much reduced. For a density of extragalactic WIMPs comparable to the critical density of the universe the count rate expected is very roughly the same as that of fast galactic WIMPs. If there is an increased density relative to critical associated with the Local Group of galaxies, say 10-30 times the critical density, there is a corresponding increase in rate and the extragalactic WIMPs would show up as a high energy shoulder in the recoil energy distribution. Evidence of such WIMPs as a separate population with these distinct properties would offer interesting information on the formation and prehistory of the galaxy.

description: On the basis of Chern-Simons field-theoretical description we propose a simple method for derivation of model interactions for Pfaffian paired states. We verify the method in the case of Pfaffian (i.e. Moore - Read) state, and derive a general form of the model interaction in the case of PH Pfaffian. More than one Landau level is needed to establish the correlations of the PH Pfaffian, and we present the values of relevant three-body pseudo-potentials for two Landau levels.

Lattice Approach to Excited TBA Boundary Flows: Tricritical Ising Model

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We show how a lattice approach can be used to derive Thermodynamic Bethe Ansatz (TBA) equations describing all excitations for boundary flows. The method is illustrated for a prototypical flow of the tricritical Ising model by considering the continuum scaling limit of the A4 lattice model with integrable boundaries. Fixing the bulk weights to their critical values, the integrable boundary weights admit two boundary fields $ξ$ and $η$ which play the role of the perturbing boundary fields $ϕ_{1,3}$ and $ϕ_{1,2}$ inducing the renormalization group flow between boundary fixed points. The excitations are completely classified in terms of (m,n) systems and quantum numbers but the string content changes by certain mechanisms along the flow. For our prototypical example, we identify these mechanisms and the induced map between the relevant finitized Virasoro characters. We also solve the boundary TBA equations numerically to determine the flows for the leading excitations.

description: Traditionally, atomic spin orientation is achieved by the transfer of angular momentum from polarised light to an atomic system. We demonstrate the mechanism of orientation generation in room-temperature caesium vapours that combines three elements: optical pumping, non-linear spin dynamics and spin-exchange collisions. Through the variation of the spin-exchange relaxation rate, the transition between an aligned and an oriented atomic sample is presented. The observation is performed by monitoring the atomic radio-frequency spectra. The measurement configuration discussed, paves the way to simple and robust radio-frequency atomic magnetometers that are based on a single low power laser diode that approach the performance of multi-laser pump-probe systems.

description: The instability of commodity prices and the hypothesis that speculative behaviour was one of its causes has brought renewed interest in futures markets. In this paper, the hedging effectiveness of European and US wheat futures markets were studied to test whether they were affected by the high price instability after 2007. Implicitly, this is a test of whether the increasing presence of speculation in futures markets have made them divorced from the physical markets. A multivariate GARCH model was applied to compute optimal hedging ratios. No important evidence was found of a change in the effectiveness of hedging after 2007.

Hence, this study aims to analyze the market structure of KRU over the period 2004-2010. By using the gravity trade model and Poisson Pseudo Maximum Likelihood (PPML) estimation method, this study confirms that the emergence of KRU increases the competition in international wheat market. The other main finding is that there is no evidence of market power of KRU wheat exporters over the South Caucasian and Central Asian countries.

description: Self-sufficiency figures based on the relationship between domestic production and consumption fail to take into account the fact that domestic production itself is dependent on imported resources. In this paper, an indicator for measuring the import content of food production industries is introduced. With the aid of Eurostat input–output tables, the total dependency on imports, comprising both direct as well as indirect imports of raw materials and intermediates, is calculated for Finland, Germany and Denmark. The results of agricultural and food manufacturing production are presented, indicating a growing trend in import dependency, including energy, chemicals, feed protein and services.

description: The dynamically generated fermion mass is investigated in the flat brane world with (4+delta)-dimensional bulk space-time, and in the Randall-Sundrum (RS) brane world. We consider the bulk Yang-Mills theory interacting with the fermion confined on a four-dimensional brane. Based on the effective theory below the reduced cutoff scale on the brane, we formulate the Schwinger-Dyson equation of the brane fermion propagator. By using the improved ladder approximation we numerically solve the Schwinger-Dyson equation and find that the dynamical fermion mass is near the reduced cutoff scale on the brane for the flat brane world with delta >= 3 and for the RS brane world. In RS brane world KK excited modes of the bulk gauge field localized around the y = pi R brane and it enhances the dynamical symmetry breaking on the brane. The decay constant of the fermion and the anti-fermion composite operator can be taken to be the order of the electroweak scale much smaller than the Planck scale. Therefore electroweak mass scale can be realized from only the Planck scale in the RS brane world due to the fermion and the anti-fermion pair condensation. That is a dynamical realization of Randall-Sundrum model which solves the weak-Planck hierarchy problem.

description: In the last decades, statistical methodology has developed rapidly, in particular in the field of regression modeling. Multivariable regression models are applied in almost all medical research projects. Therefore, the potential impact of statistical misconceptions within this field can be enormous Indeed, the current theoretical statistical knowledge is not always adequately transferred to the current practice in medical statistics. Some medical journals have identified this problem and published isolated statistical articles and even whole series thereof. In this systematic review, we aim to assess the current level of education on regression modeling that is provided to medical researchers via series of statistical articles published in medical journals. The present manuscript is a protocol for a systematic review that aims to assess which aspects of regression modeling are covered by statistical series published in medical journals that intend to train and guide applied medical researchers with limited statistical knowledge. Statistical paper series cannot easily be summarized and identified by common keywords in an electronic search engine like Scopus. We therefore identified series by a systematic request to statistical experts who are part or related to the STRATOS Initiative (STRengthening Analytical Thinking for Observational Studies). Within each identified article, two raters will independently check the content of the articles with respect to a predefined list of key aspects related to regression modeling. The content analysis of the topic-relevant articles will be performed using a predefined report form to assess the content as objectively as possible. Any disputes will be resolved by a third reviewer. Summary analyses will identify potential methodological gaps and misconceptions that may have an important impact on the quality of analyses in medical research. This review will thus provide a basis for future guidance papers and tutorials in the field of regression modeling which will enable medical researchers 1) to interpret publications in a correct way, 2) to perform basic statistical analyses in a correct way and 3) to identify situations when the help of a statistical expert is required.

description: We have investigated the electron attachment dynamics of uracil in water using accurate wave-function and QM/MM methods. The initial electron attached state is found to be localized on the water and mixing of electronic and nuclear degrees of freedom leads to the transfer of electron from the water to the uracil. The water molecules around the uracil stabilize the uracil bound anion by creating an extensive hydrogen-bonding network. The presence of the bulk water environment accelerates the rate of electron attachment to uracil and the complete electron transfer from water to the uracil happens at a picosecond time scale. The degree of solvation of the aqueous electron can lead to a difference in the initial stabilization of the uracil bound anion but at a longer time scale the anion formed due to the attachment of both surface-bound and bulk solvated electrons behaves similarly.

description: We explore the effect of mechanical strain on the electronic spectrum of patterned graphene based heterostructures. We focus on the competition of Kekulé-O type distortion favoring a trivial phase and commensurate Kane-Mele type spin-orbit coupling generating a topological phase. We derive a simple low-energy Dirac Hamiltonian incorporating the two gap promoting mechanisms and include terms corresponding to uniaxial strain. The derived effective model explains previous ab initio results through a simple physical picture. We show that while the trivial gap is sensitive to mechanical distortions, the topological gap stays resilient.

description: We analyze the effect of different trade preferences granted to Southern and Eastern Mediterranean Countries (SEMCs). Specifically, we focus on monthly exports of four fruits and vegetables from Morocco to EU countries. We construct three indicators that consider different types of preferences and trade policies, and we include them in a gravity model. Furthermore, quantitative limits for these preferences are modelled. Our main results are that trade preferences are significant in positively determining exports from Morocco to the EU. Therefore, the Moroccan policy option that consists on negotiating trade preferences in key competitive sectors is translated into export increases.

description: We review our version of the classical field approximation to the dynamics of a finite temperature Bose gas. In the case of a periodic box potential, we investigate the role of the high momentum cut-off, essential in the method. In particular, we show that the cut-off going to infinity limit decribes the particle number going to infinity with the scattering length going to zero. In this weak interaction limit, the relative population of the condensate tends to unity. We also show that the cross-over energy, at which the probability distribution of the condensate occupation changes its character, grows with a growing scattering length. In the more physical case of the condensate in the harmonic trap we investigate the dissipative dynamics of a vortex. We compare the decay time and the velocities of the vortex with the available analytic estimates.

description: Addressing competition in Germany’s dairy sector, this paper investigates imperfect competition on the raw milk market. By using the conjectural variation approach to determine dairy processors market power towards raw milk producers, regions in Germany with a high degree of imperfect competition can be detected. Therefore a panel data set of dairy processor's price data and related federal state level farm structural and market information data is used which also allows to analyze other price determinants like structural change and spatial aspects on raw milk prices.

description: The present study aims to formulate a concept for an electronic marketplace which offers efficient support primarily to small and medium-sized businesses operating as agricultural producers and service providers in order to facilitate their purchase and efficient use of production inputs, product development, the improvement of production, the establishment of business contacts and the sales of produced goods. The concept of the electronic agricultural purchasing marketplace embodies a novel approach to today’s agriculture based on modern technologies offering an opportunity to both agricultural producers and suppliers providing production input materials to maintain communication, perform administrative tasks and trade with each other electronically within a single system that has several unique functions.
Warm dark matter chills out: constraints on the halo mass function and the free-streaming length of dark matter with 8 quadruple-image strong gravitational lenses

description: The free-streaming length of dark matter depends on fundamental dark matter physics, and determines the abundance and concentration of dark matter halos on sub-galactic scales. Using the image positions and flux ratios from eight quadruply-imaged quasars, we constrain the free-streaming length of dark matter and the amplitude of the subhalo mass function (SHMF). We model both main deflector subhalos and halos along the line of sight, and account for warm dark matter (WDM) free-streaming effects on the mass function and mass-concentration relation. By calibrating the scaling of the SHMF with host halo mass and redshift using a suite of simulated halos, we infer a global normalization for the SHMF. We account for finite-size background sources, and marginalize over the mass profile of the main deflector. Parameterizing dark matter free-streaming through the half-mode mass $m_{\rm{hm}}$, we constrain the thermal relic particle mass $m_{\rm{DM}}$ corresponding to $m_{\rm{hm}}$. At $95 \%$ CI: $m_{\rm{hm}} < 10^{7.8} M_{\odot}$ ($m_{\rm{DM}} > 5.2 \ \rm{keV}$). We disfavor $m_{\rm{DM}} = 4.0 \rm{keV}$ and $ m_{\rm{DM}} = 3.0 \rm{keV}$ with likelihood ratios of 7:1 and 30:1, respectively, relative to the peak of the posterior distribution. Assuming cold dark matter, we constrain the projected mass in substructure between $10^6 - 10^{9} M_{\odot}$ near lensed images. At $68 \%$ CI, we infer $2.0 - 6.1 \times 10^{7} M_{\odot} \rm{kpc^{-2}}$, corresponding to mean projected mass fraction $\bar{f}_{\rm{sub}} = 0.035_{-0.017}^{+0.021}$. At $95 \%$ CI, we obtain a lower bound on the projected mass of $0.6 \times 10^{7} M_{\odot} \rm{kpc^{-2}}$, corresponding to $\bar{f}_{\rm{sub}} > 0.005$. These results agree with the predictions of cold dark matter.

description: Body-size reduction is considered an important response to current climate warming and has been observed during past biotic crises, including the Pliensbachian–Toarcian crisis, a second-order mass extinction. However, in fossil cephalopod studies, the mechanisms and their potential link with climate are rarely investigated and palaeobiological scales of organization are not usually differentiated. Here, we hypothesize that belemnites reduce their adult size across the Pliensbachian–Toarcian boundary warming event. Belemnite body-size dynamics across the Pliensbachian–Toarcian boundary in the Peniche section (Lusitanian Basin, Portugal) were analysed based on the newly collected field data. We disentangle the mechanisms and the environmental drivers of the size fluctuations observed from the individual to the assemblage scale. Despite the lack of a major taxonomic turnover, a 40% decrease in rostrum volume is observed across the Pliensbachian–Toarcian boundary, before the Toarcian Oceanic Anoxic Event where belemnites go locally extinct. The pattern is mainly driven by a reduction in adult size of the two dominant species, Pseudohastites longiformis and Passaloteuthis bisulcata. Belemnite-size distribution is best correlated with fluctuations in a palaeotemperature proxy (stable oxygen isotopes); however, potential indirect effects of volcanism and carbon cycle perturbations may also play a role. This highlights the complex interplay between environmental stressors (warming, deoxygenation, nutrient input) and biotic variables (productivity, competition, migration) associated with these hyperthermal events in driving belemnite body size.

description: We show that a Fuchsian differential equation having five regular singular points admits solutions in terms of a single generalized hypergeometric function for infinitely many particular choices of equation parameters. Each solution assumes four restrictions imposed on the parameters: two of the singularities should have non-zero integer characteristic exponents and the accessory parameters should obey polynomial equations.

description: The aim of this paper is to emphasise the importance of the institutional support in the process of application and registration of Macedonian agro-food products for PDO/PGI protection. The research was supported with the results of pilot project that study eleven potential agro-food products proposed as eligible for PDO/PGI protection in Macedonia. The field research included a survey of 46 entities and was conducted as a technical support of the Macedonian Ministry of Agriculture, Forestry and Water Economy. The Ministry was at the same time adopting by-laws and rulebooks for establishment of a well defined PDO/PGI protection system. In this respect, we consider this system of protection as a tool for improving the competitive position of the producers, by understanding the current situation in agricultural sector, the problems and constrains and the institutional inefficiencies that appear in the process. The results show that in order to achieve an effective PDO/PGI system, there is a need for strong coordination among the Governmental institutions (Ministry, advisory system, regional offices, etc), the scientific researchers and the producers. This cooperation is crucial in order to provide support in the producers’ decision making process in the registration of products with PDO and PGI protection.

description: In this paper, exact one-point functions of N=1 super-Liouville field theory in two-dimensional space-time with appropriate boundary conditions are presented. Exact results are derived both for the theory defined on a pseudosphere with discrete (NS) boundary conditions and for the theory with explicit boundary actions which preserves super conformal symmetries. We provide various consistency checks. We also show that these one-point functions can be related to a generalized Cardy conditions along with corresponding modular $S$-matrices. Using this result, we conjecture the dependence of the boundary two-point functions of the (NS) boundary operators on the boundary parameter.
