description: The overall purpose of this study is to conduct exploratory research on the market potential for local organic sales outlets for small-to-medium scale farmers in the South Atlantic Sub-region of the U.S. The objectives are as follow: (1) identification of the leading organic produce in each state of the South Atlantic, (2) identification of supermarket chains offering the leading organic produce of the South Atlantic, (3) identification of the leading produce with the highest premium potential in the South Atlantic, and (4) identification of local organic supply chain linkages for the leading organic produce in the South Atlantic. Initially, this study proposed to identify established supply chains of leading organic produce within the state of North Carolina. However, the state ranked only 16th in the U.S. in the number of certified/exempt farms, with only 171 farms receiving 100 percent of the total value of sales from organic production. With limited impact to North Carolina’s economy or agribusiness industry, we expanded the study to include states within the entire South Atlantic sub-region of the U.S. – Florida, Georgia, South Carolina, North Carolina, Virginia, West Virginia, Maryland, and Delaware. We used the 2007 Census of Agriculture, 2008 Organic Production Survey and Perishables Group FreshFacts® data from August of 2009 to 2010, and the 2006 National Farmers Market Manager Survey to identify patterns. Conventional and certified production, retail sales, and organic retail premiums are identified and evaluated to gain more insight of established supply chains. The data shows potential for small scale producers with $5,000 or less by value of sales to market their goods as ‘organic’ due to exemption from the certification process at consumer direct sales outlets. However, small-to-medium farms (value of sales greater than $5,000 but less than $250,000) with USDA ‘certification’ labels may have greater opportunities to establish contracts with wholesalers as well as market their produce in multiple sales outlets. Directions for further research will include 1) evaluating market power of the contracting agent in the market for certified organic produce and 2) assessing the benefits and costs to producers and sales outlets for ‘organic’ produce.

description: We present new 2D high resolution Fabry-Perot spectroscopic observations of 152 star-forming galaxies which are part of the $Herschel$ Reference Survey (HRS), a complete $K$-band selected, volume-limited sample of nearby galaxies, spanning a wide range in stellar mass and morphological type. Using improved data reduction techniques that provide adaptive binning based on Voronoi tessellation, using large field-of-view observations, we derive high spectral resolution (R$>$10,000) H$α$ datacubes from which we compute H$α$ maps and radial 2D velocity fields that are based on several thousand independent measurements. A robust method based on such fields allows us to accurately compute rotation curves and kinematical parameters, for which uncertainties are calculated using a method based on the power spectrum of the residual velocity fields. We check the consistency of the rotation curves by comparing our maximum rotational velocities to those derived from HI data, and computing the $i$-band, NIR, stellar and baryonic Tully-Fisher relations. We use this set of kinematical data combined to those available at other frequencies to study for the first time the relation between the dynamical and the total baryonic mass (stars, atomic and molecular gas, metals and dust), and derive the baryonic and dynamical main sequence on a representative sample of the local universe.
description: 43 pages, 18 figures, 4 tables. The complete version of the tables, figures and all the Fabry-Perot data will be made available online at the CDS, on the HRS dedicated database HeDAM (https://hedam.lam.fr/), and on the Fabry-Perot database (https://cesam.lam.fr/fabryperot)

description: An extremal model for the plasticity of amorphous materials is studied in a simple two-dimensional anti-plane geometry. The steady-state is analyzed through numerical simulations. Long-range spatial and temporal correlations in local slip events are shown to develop, leading to non-trivial and highly anisotropic scaling laws. In particular, the plastic strain is shown to statistically concentrate over a region which tends to align perpendicular to the displacement gradient. By construction, the model can be seen as giving rise to a depinning transition, the threshold of which (i.e. the macroscopic yield stress) also reveal scaling properties reflecting the localization of the activity.

description: Taxonomic studies on parasitic Hymenoptera were mainly based on comparative morphology of adult wasps and occasionally on molecular surveys. Nowadays, wing interference patterns (WIPs) are applied to separate cryptic species of microhymenoptera. In our current research, colour characters of WIPs are quantified as wing interference colours (WICs), for the first time. In this regard, we demonstrated that statistical analysis of WICs is able to perform as well as side-by-side comparison of WIPs. WICs is a new concept including three main wing colours and their qualitative attributes. WICs of five Eurytoma species (Hymenoptera: Chalcidoidea, Eurytomidae), E. acroptilae Zerova, E. amygdali (Enderlein), E. caninae Lotfalizadeh and Delvare, E. plotnikovi Nikols’kaya and E. rosae Nees were analysed, for the first time. For this purpose, six colour parameters including red, green and blue (RGB) as well as hue, saturation and value (HSV) were compared. WICs alone could differentiate Eurytoma species. Geographic variation and sex determination were also examined based on WICs. Since these characters were similar and unique in both sexes, they were very useful for linking conspecific males and females. The study of different populations of the same species confirmed the stability of WICs.

description: Barrier primitives provided by standard parallel programming APIs are the primary means by which applications implement global synchronisation. Typically these primitives are fully-committed to synchronisation in the sense that, once a barrier is entered, synchronisation is the only way out. For message-passing applications, this raises the question of what happens when a message arrives at a thread that already resides in a barrier. Without a satisfactory answer, barriers do not interact with message-passing in any useful way. In this paper, we propose a new refutable barrier primitive that combines with message-passing to form a simple, expressive, efficient, well-defined API. It has a clear semantics based on termination detection, and supports the development of both globally-synchronous and asynchronous parallel applications. To evaluate the new primitive, we implement it in a prototype large-scale message-passing machine with 49,152 RISC-V threads distributed over 48 FPGAs. We show that hardware support for the primitive leads to a highly-efficient implementation, capable of synchronisation rates that are an order-of-magnitude higher than what is achievable in software. Using the primitive, we implement synchronous and asynchronous versions of a range of applications, observing that each version can have significant advantages over the other, depending on the application. Therefore, a barrier primitive supporting both styles can greatly assist the development of parallel programs.

description: To apply the high-precision realistic nucleon-nucleon ($NN$) potentials on the investigations of relativistic many-body methods, the new versions of charge-dependent Bonn (CD-Bonn) $NN$ potential are constructed within the pseudovector pion-nucleon coupling instead of the pseudoscalar type in the original CD-Bonn potential worked out by Machleidt [Phys. Rev. C 63, 024001 (2001)]. Two effective scalar mesons are introduced, whose coupling constants with nucleon are independently determined at each partial wave for total angular momentum $J\leq 4$, to describe the charge dependence of $NN$ scattering data precisely, while the coupling constants between vector, pseudovector mesons and nucleon are identical in all channels. Three revised CD-Bonn potentials adopting the pseudovector pion-nucleon couplings (pvCD-Bonn) are generated by fitting the Nijmegen PWA phase shift data and deuteron binding energy with different pion-nucleon coupling strengths, which can reproduce the phase shifts at spin-single channels and low-energy $NN$ scattering parameters very well, and provide the significantly different mixing parameters at spin-triplet channels. Furthermore, the $D$-state probabilities of deuteron from these potentials range from $4.22\%$ to $6.05\%$. It demonstrates that these potentials contain different components of tensor force, which will be useful to discuss the roles of tensor force in nuclear few-body and many-body systems.

description: Laos is a small, open, least-developed country (LDC) in Southeast Asia. However, it is a resource-rich economy with over 570 identified mineral deposits. As a result, Laos has experienced massive inflows of foreign direct investment (FDI) in the mining and hydroelectricity sectors since 2003. Despite the likelihood that resource booms will carry both positive and negative impacts on the Lao economy, this issue has been underresearched in Laos. This study thus lays out a framework to quantify the impacts of resource booms on the macro economy and on poverty in Laos using a computable general equilibrium (CGE) model. We find that the higher capital stock and productivity led to increased value added, production, exports and investment in the mining sector, resulting in higher real GDP, exports and investment. Unfortunately, the associated Dutch disease effects (particularly real exchange rate appreciation) negatively impact real production and value added in agriculture, industry and government services.

description: We discuss effects of cosmological moduli fields on the cosmic microwave background (CMB). If a modulus field ϕonce dominates the universe, the CMB we observe today is from the decay of ϕand its anisotropy is affected by the primordial fluctuation in the amplitude of the modulus field. Consequently, constraints on the inflaton potential from the CMB anisotropy can be relaxed. In particular, the scale of the inflation may be significantly lowered. In addition, with the cosmological moduli fields, correlated mixture of adiabatic and isocurvature fluctuations may be generated, which results in enhanced CMB angular power spectrum at higher multipoles relative to that of lower ones. Such an enhancement can be an evidence of the cosmological moduli fields, and may be observed in future satellite experiments.

description: This paper discusses the question of the concentrated pattern of agricultural development in Brazil, as expressed in the predominance of large-scale production, high level of mechanization and low absorption of non-qualified labor. It is proposed, initially, the existence of two conflicting explanations for this fact: the first, that blames our historical heritage, characterized by the predominance of the latifundio, and the second, that sees in this fact a technological determinism, with the implication that lesser concentration in agriculture would involve a loss of economic efficiency. This paper, however, attributes to the labor, land and credit policies directed to agriculture, instituted in the decade of 1960, the major responsibility for this problem. As the analysis shows, these policies turned unviable the agricultural temporary labor market and family farm, at the same time that they stimulated agricultural mechanization and large-scale production. The paper ends up proposing a deregulation both of agricultural labor and land markets, as well as a drastic reduction in the subsidized agricultural credit.

description: Constant droughts especially in the Arid and Semi-Arid Lands (ASAL) have led to recurrent crop failures and livestock losses. Households have therefore resulted to other alternatives which can provide both food and income. Trade in indigenous fruits contributes to livelihoods through income generation and as a safety net for consumption and income smoothing. This paper presents the analysis of economic returns from harvesting and marketing indigenous fruits and the socio economic factors that influence participation in trade of indigenous fruits. The results are based on a survey conducted in Nuu division, Mwingi District, where 120 randomly selected households were interviewed using a pre-tested semi-structured questionnaire. Logistic regression model, Gross Margin Analysis, and Benefit cost ratios were used during the analysis. Data was processed and analyzed using SPSS20. The Gross margins depicted harvesting of indigenous fruits for trade as a profitable venture. High benefit cost ratios of greater than 3.0 were reported in all the three fruits under study. Higher returns to labour and other associated costs were notably reported in the distant market as compared to the local market. The analysis of socioeconomic factors influencing participation in indigenous fruits’ trade identified household size, gender, form of employment and market distance to be significant variables. Respectively, market distance and household size negatively and positively influenced participation in harvesting indigenous fruits for trade. The female headed households and low income earners were more likely to participate in trade of indigenous fruits.

description: Dairy is a key investment sector for the Government of Malawi. Advocacy institutions operating in the country have successfully lobbied for increasing the duty applied for powder milk, with the aim of improving the price received by farmers. It should be noted that whilst an increase of the price paid to farmers would rise their revenues (assuming the same amount of milk delivery), it might also bring additional blessings, in the sense that if farmers respond to prices, they may rise their revenues beyond the increase in prices, and furthermore, they would expand their delivery of milk to processors offsetting the imports of powder milk and reducing their idle capacity in factories. Hence, the purpose of this paper is to measure the responsiveness of the deliveries of milk at the milk bulking groups to prices paid to farmers (i.e., the elasticity of supply faced by processors). This is done using a unique dataset that comprises information by milk bulking group from January 2009 to February 2013. The results indicate that the supply of milk is price responsive. The price elasticity in the short term is equal to 0.6 and in the long term is 1.44. This indicates that farmers’ revenues not only benefit from an increase in the price of milk but also from the increase in the quantity produced. Furthermore, it indicates the possibility that domestic producers could offset imports of milk powder by processors, although answer to this requires further research.

description: We use statistical results from a large sample of about 500 blazars, based on two surveys, the Deep X-ray Radio Blazar Survey (DXRBS), nearly complete, and the RASS-Green Bank survey (RGB), to provide new constraints on the spectral energy distribution of blazars, particularly flat-spectrum radio quasars (FSRQ). This reassessment is prompted by the discovery of a population of FSRQ with spectral energy distribution similar to that of high-energy peaked BL Lacs. The fraction of these sources is sample dependent, being ~ 10% in DXRBS and ~ 30% in RGB (and reaching ~ 80% for the Einstein Medium Sensitivity Survey). We show that these ``X-ray strong'' radio quasars, which had gone undetected or unnoticed in previous surveys, indeed are the strong-lined counterparts of high-energy peaked BL Lacs and have synchrotron peak frequencies, nu_peak, much higher than ``classical'' FSRQ, typically in the UV band for DXRBS. Some of these objects may be 100 GeV - TeV emitters, as are several known BL Lacs with similar broadband spectra. Our large, deep, and homogeneous DXRBS sample does not show anti-correlations between nu_peak and radio, broad line region, or jet power, as expected in the so-called ``blazar sequence'' scenario. However, the fact that FSRQ do not reach X-ray-to-radio flux ratios and nu_peak values as extreme as BL Lacs and the elusiveness of high nu_peak - high-power blazars suggest that there might be an intrinsic, physical limit to the synchrotron peak frequency that can be reached by strong-lined, powerful blazars. Our findings have important implications for the study of jet formation and physics and its relationship to other properties of active galactic nuclei.

Comparative Therapeutic Effects of Salbutamol and a Natural Herbal Mixture on Immune Modulation in Ovalbumin-Induced Asthma: A Rat Model Study
Creators: name: Areola, Gideon
Publisher: name: Zenodo
Year: 2024
Subjects: subject: Asthma

description: Abstract

Background: This study investigates the effects of salbutamol, a β2-adrenergic receptor agonist, and a natural herbal mixture (garlic, honey, lime, and unripe pawpaw seeds) on the spleen of ovalbumin-induced asthmatic Wistar rats. The research aims to explore the therapeutic potential of these treatments in managing asthma and allergic rhinitis by assessing their effects on the spleen, a key organ in immune regulation.

Methods: Twenty female Wistar rats weighing between 97–124g were divided into four groups. Group A (control) received physiological saline, Group B was induced with 2 mg/kg of ovalbumin, Group C was induced with ovalbumin and treated with 2 mg/kg salbutamol, and Group D was induced with ovalbumin and treated with 2 mg/kg of a natural herbal mixture. Hematological parameters, including packed cell volume (PCV), white blood cell (WBC) count, lymphocytes, and neutrophils, were analyzed. Histological analysis of spleen tissue was also conducted.

Results: Significant increases in PCV, WBC, lymphocytes, and neutrophils were observed in the ovalbumin-induced group (Group B). Treatment with salbutamol and the herbal mixture reduced these increases, with the herbal mixture showing promising immunomodulatory effects.

Conclusion: Both salbutamol and the herbal mixture alleviated spleen dysfunction and immune system dysregulation in allergic conditions. The herbal mixture, with its anti-inflammatory, antioxidant, and immune-boosting properties, may serve as an effective alternative or complementary treatment for managing asthma. Further research is needed to explore their mechanisms and long-term benefits.

description: Extra dimensions (ED) have been used as attempts to explain several phenomena in particle physics over the years. In this paper we investigate the role of an abelian gauge field as mediator of the interaction between dark matter (DM) and Standard Model (SM) particles, in a model with two flat and transverse ED compactified on the chiral square. DM is confined in a thin brane, localized at the origin of the chiral square, while the SM is localized in a finite width brane, lying in the opposite corner of the square. A brane-localized kinetic term is present in the DM brane, while in the fat brane it is not allowed. In this model the kinetic mixing is not required because we assume that the SM particles couple to the mediator through their $B-L$ charges, while DM couples to it via a dark charge. Assuming a complex scalar field as DM candidate it is possible to obtain the observed DM relic abundance and avoid direct detection constraints for some parameter choices.

description: First principle FLAPW band calculations of the new superconductor MgB2 were performed and the polarization function P12(Q) between the two p-bands mainly formed of boron pz-orbital was calculated. We found that P12(Q) is substantially enhanced around Q=(0,0,p/c), which supports the two-band mechanism of superconductivity for MgB2. P12(Q) peaks at Qz ~ 0.3(2p/c) and Qz \~ 0.5(2p/c). These two peaks are related to the nesting of these Fermi surfaces, but significantly deviates from the position expected from the simplest tight-binding bands for the p-bands. From the calculations for different lattice parameters, we have found significant dependences on the isotopic species of B and on the pressure effect of the polarization function in accordance with the respective changes of Tc in the above-mentioned framework.

description: With the surge of research in quantum information, the issue of producing entangled states has gained prominence. Here, we show that judiciously bringing together two systems of strongly interacting electrons with vastly differing ground states - the gapped BCS superconductor and the Luttinger liquid, - can result in quantum entanglement. We propose three sets of measurements involving single-walled metallic carbon nanotubes (SWNT) which have been shown to exhibit Luttinger liquid physics, to test our claim and as nanoscience experiments of interest in and of themselves.

description: Stiffness and hysteretic energy losses are calculated for a magnetically levitating system composed of a type-II superconductor and a permanent magnet when a small vibration is produced in the system. We consider a cylindrically symmetric configuration with only vertical movements and calculate the current profiles under the assumption of the critical state model. The calculations, based on magnetic energy minimization, take into account the demagnetization fields inside the superconductor and the actual shape of the applied field. The dependence of stiffness and hysteretic energy losses upon the different important parameters of the system such as the superconductor aspect ratio, the relative size of the superconductor-permanent magnet, and the critical current of the superconductor are all systematically studied. Finally, in view of the results, we provide some trends on how a system such as the one studied here could be designed in order to optimize both the stiffness and the hysteretic losses.

description: We discuss the asymptotic dynamical evolution of spatially homogeneous brane-world cosmological models close to the initial singularity. We find that generically the cosmological singularity is isotropic in Bianchi type IX brane-world models and consequently these models do not exhibit Mixmaster or chaotic-like behaviour close to the initial singularity. We argue that this is typical of more general cosmological models in the brane-world scenario. In particular, we show that an isotropic singularity is a past-attractor in all orthogonal Bianchi models and is a local past-attractor in a class of inhomogeneous brane-world models.

description: Two-dimensional MoS2 has emerged as promising material for nanoelectronics and spintronics due to its exotic properties. However, high contact resistance at metal semiconductor MoS2 interface still remains an open issue. Here, we report electronic properties of field effect transistor devices using monolayer MoS2 channels and permalloy (Py) as ferromagnetic (FM) metal contacts. Monolayer MoS2 channels were directly grown on SiO2/Si substrate via chemical vapor deposition technique. The increase in current with back gate voltage shows the tunability of FET characteristics. The Schottky barrier height (SBH) estimated for Py/MoS2 contacts is found to be +28.8 meV (zero-bias), which is the smallest value reported so-far for any direct metal (magnetic or non-magnetic)/monolayer MoS2 contact. With the application of gate voltage (+10 V), SBH shows a drastic reduction down to a value of -6.8 meV. The negative SBH reveals ohmic behavior of Py/MoS2 contacts. Low SBH with controlled ohmic nature of FM contacts is a primary requirement for MoS2 based spintronics and therefore using directly grown MoS2 channels in the present study can pave a path towards high performance devices for large scale applications.

description: There are various types of risk associated with trading options. Traders typically manage such risks with the help of various partial derivatives of option prices known as Greeks. Experimental and anecdotal evidence suggests that mental accounting matters in the valuation of options. Mental accounting changes the values of Greeks significantly with crucial implications for risk management. I show that for a call option, delta-risk is under-estimated, gamma risk is over-estimated, and the value-decay due to the passage of time is under-estimated. For a put option, all three types of risks are over-estimated. I also show that covered call writing is more profitable when mental accounting influences prices.

description: The Wisconsin H Alpha Mapper has been used to set the first deep upper limits on the intensity of diffuse H alpha emission from warm ionized gas in the Local Group dwarf spheroidal galaxies (dSphs) Draco and Ursa Minor. Assuming a velocity dispersion of 15 km/s for the ionized gas, we set limits for the H alpha intensity of less or equal to 0.024 Rayleighs and less or equal to 0.021 Rayleighs for the Draco and Ursa Minor dSphs, respectively, averaged over our 1 degree circular beam. Adopting a simple model for the ionized interstellar medium, these limits translate to upper bounds on the mass of ionized gas of approximately less than 10% of the stellar mass, or approximately 10 times the upper limits for the mass of neutral hydrogen. Note that the Draco and Ursa Minor dSphs could contain substantial amounts of interstellar gas, equivalent to all of the gas injected by dying stars since the end of their main star forming episodes more than 8 Gyr in the past, without violating these limits on the mass of ionized gas.

Analogy Making in Complete and incomplete Markets: A New Model for Pricing Contingent Claims

subject: Risk Premium

description: A key limitation of the Black Scholes model is that it assumes a complete market (claims are replicable with existing assets). We put forward a new option pricing formula that does not require market completeness. The new formula is based on the idea that people rely on, what can be termed, the principle of analogy making while valuing assets. The principle of analogy making says that similar assets should offer the same returns. This is in contrast with the principle of no arbitrage which says that identical assets should offer the same returns. Analogy making is consistent with experimental and anecdotal evidence. I show that the principle of analogy making is a special case of the coarse thinking model of Mullainathan, Schwartzstein, and Shleifer (2008). I then apply the coarse thinking/analogy making model to option pricing and put forward a new option pricing formula. The new formula differs from the Black Scholes formula due to the appearance of a parameter in the formula that captures the risk premium on the underlying. The new formula, called the analogy option pricing formula, provides an explanation for the implied volatility skew puzzle in equity options. The key empirical predictions of the analogy formula are also discussed.

description: Objectives: To evaluate the cost-effectiveness of olmesartan/amlodipine fixed-dose combination vs olmesartan and amlodipine free combination, amlodipine single drug, and valsartan/amlodipine fixed-dose combination in the treatment of hypertensive patients from payer perspective in China. Methods: A Markov model was constructed, which included five health states of hypertensive patients who are aged 35–84 years at baseline and free of cardiovascular disease. Clinical data were obtained from a network meta-analysis. Epidemiology data, adverse events (AEs), cost, and utility data were obtained from the literature. The cost associated with AEs was estimated based on the cost of same symptoms of hypertensive patients in an electric medical record database. The model projected quality-adjusted life years (QALYs) gained, total costs per patient in a 20-year time horizon, and incremental cost-effectiveness ratios. Probability sensitivity analyses (PSA) and one-way sensitivity analyses were conducted for the main parameters to test the robustness of the model. Results: Compared to olmesartan and amlodipine free combination, amlodipine, and valsartan/amlodipine fixed-dose combination, treatment with olmesartan/amlodipine fixed-dose combination led to fewer CVD events and deaths; resulted in an incremental cost of ¥−5,439 ($−791.36), ¥6,530 ($950.09), and ¥−1,019 ($−148.26) and gained additional QALYs of 0.052, 0.094, and 0.037 per patient, respectively. Compared with olmesartan and amlodipine free combination and valsartan/amlodipine fixed-dose combination, olmesartan/amlodipine fixed-dose combination was dominant. Compared with amlodipine alone, the incremental cost-effectiveness ratios were below the WHO recommended cost-effectiveness threshold, indicating the olmesartan/amlodipine fixed-dose combination was a cost-effective option for hypertensive patients in China. The 10-years’ time horizon scenario analysis showed similar results to the 20-years’ time horizon. Probabilistic sensitivity analysis and one-way sensitivity analyses showed the robustness of the model results. Conclusions: Olmesartan/amlodipine fixed-dose combination confers better health outcomes and costs less compared with olmesartan and amlodipine free combination and valsartan/amlodipine fixed-dose combination, and is cost-effective compared to amlodipine for hypertension treatment in China.
