description: Average custom rates for eight common farming operations as reported in surveys done in Iowa and Kansas in 1995 were inflated to 2015 values (Iowa) and 2013 values (Kansas) using the Prices Paid indices gathered by the National Agricultural Statistics Service (NASS). The projected rates were generally higher than the average rates reported in surveys completed in the corresponding years, except for planting. Possible explanations for the lag in custom rates include uncertainty about fuel prices, improved fuel efficiency, improved field efficiency, adoption of larger equipment where economies of size exist, and extension of field hours per season.

description: Reaction and elastic differential cross sections are calculated for light nuclei in the framework of the Glauber theory. The optical phase-shift function is evaluated by Monte Carlo integration. This enables us to use the most accurate wave functions and calculate the phase-shift functions without approximation. Examples of proton nucleus (e.g. p-$^6$He, p-$^6$Li) and nucleus-nucleus (e.g. $^6$He$-^{12}$C) scatterings illustrate the effectiveness of the method. This approach gives us a possibility of a more stringent analysis of the high-energy reactions of halo nuclei.

description: New azo-phenylbenzothiazole moiety-based liquid crystals with diverse substituents/groups (H, OH, CH3, Cl, F) at position-3 of the central benzene ring were prepared and characterised. All synthesised compounds were characterised using H-NMR and FT-IR spectroscopy, mass spectrometry and elemental analysis. Thermal properties of mesophase of these liquid crystal compounds were studied to reveal that they all exhibited an enantiotropic nematic phase except for the compound bearing an OH group, i.e. EB1-OH. Two new azo-benzothiazole analogous, where the azo group is directly attached to the thiazole ring, were synthesised. The mesomorphic properties of the azo-phenylbenzothiazole liquid crystalline compounds were compared with these compounds to evaluate the effect of the nature of the lateral substituents on their mesomorphic properties.

description: This paper analyzes the costs and returns of meat goat farms for the US and Southeastern US region. We compare components of costs and returns of meat goat production based on operation size (small and large) and targeted marketing segment (slaughter, breeding/show, and mixed). Our costs and returns analyses show that input expenses decrease substantially with increasing scale of operation. Increasing the number of meat goats for small meat goat farms can lead to reduced input expenses per acre.

description: Genus Aleurodicus Douglas
 Aleurodicus Douglas in Morgan, 1892:32. Type species: Aleurodicus anonae Morgan (a synonym of A. cocois Curtis) by subsequent designation of Quaintance, 1908: 8.
 Aleurodicus (Lecanoideus) Quaintance & Baker, 1913: 70
 Lecanoideus Quaintance & Baker; Costa Lima, 1928: 133. [Synonymised with Aleurodicus by Martin, 2008: 14].
 Comments. The genus Aleurodicus was revised by Martin (2008) and currently comprises 35 described species. Aleurodicus puparia are characterised by having 4 pairs of large subdorsal abdominal compound pores, and most species also with one or two much smaller abdominal pairs posterior to the other four; 12 pairs of submarginal setae, and submedian cephalothoracic setae, present; submargin and/or dorsal disc usually punctuated by pores of several types.
 Lecanoideus was described as a subgenus of Aleurodicus, but was later raised to full genus by Costa-Lima (1928). Martin et al. (1997: 1269–1270) had already suggested the need for a revision of the genus, and Martin (2008) concluded that Lecanoideus should be regarded as a junior synonym of Aleurodicus.

description: Reduced Ni on highly basic lanthanide supports in isopropanol (2-PrOH) was proved to be an efficient catalyst and an economically viable alternative to modified noble metal catalytic systems for the direct hydrogenolysis of tetrahydrofurfuryl alcohol (THFA) and furfural to 1,5-pentanediol (1,5-PeD). For the first time, a continuous catalytic transfer hydrogenolysis (CTH) process for the selective hydrogenolysis of THFA to 1,5-PeD was developed using Ni-La(R) in 2-PrOH. A maximum 1,5-PeD yield of 73% with an productivity of 1.4 mmol g(cat)-1 h-1 was achieved under continuous CTH conditions.

description: One alternative to a cow-calf-yearling operation is a stocker operation. Relative profitability of cow-calf-yearling versus stockers is well documented. Little is known, however, about the economics of the transition process itself. We analyze benefits, costs, and risks of switching from cow-calf-yearling to stockers over a one-year versus seven-year transition period. Results show a gradual transition is superior to an abrupt transition. A gradual transition to stockers generates more net present value than cowcalf-yearlings, given a sufficiently high discount rate or short planning horizon. Farm managers and consultants should include transition-period benefits and costs when analyzing alternative enterprises.

description: We study the structural characteristic of the variable DA white dwarf G117B-15A by applying the methods of asteroseismology. For such a purpose, we construct white dwarf evolutionary models considering a detailed and up-to-date physical description as well as several processes responsible for the occurrence of element diffusion. We have considered several thickness for the outermost hydrogen layer, whereas for the inner helium-, carbon- and oxygen-rich layers we considered realistic profiles predicted by calculations of the white dwarf progenitor evolution. The evolution of each of the considered model sequences were followed down to very low effective temperature; in particular, from 12500K on we computed the dipolar, linear, adiabatic oscillations with low radial order. We find that asteroseismological results are not univocal regarding mode identification for the case of G117B-15A. However, our asteroseismological results are compatible with spectroscopical data only if the observed periods of 215.2, 271.0 and 304.4 s are due to dipolar modes with $k=2, 3, 4$ respectively. Our calculations indicate that the best fit to the observed period pattern of G117B-15A corresponds to a DA white dwarf structure with a stellar mass of 0.525 \msun, with a hydrogen mass fraction \lmh$\gtrsim$-3.83 at an effective temperature \teff$\approx$11800K.

description: This article is a continuation of previously published ‘Liquid crystals for IR: Part I’ article. Several homologous series of laterally halogenated and perfluoroalkyl- or perfluoroalkoxy-terminated tolanes derivatives have been synthesised. Obtained compounds were divided into three families, i.e. tolanes, phenyltolanes, bistolanes and their mesomorphic properties, phase transition temperatures and enthalpies were determined. The influence of the length of the core, type and position of substituents in the molecular core has been analysed. The lack of aliphatic protons in molecular structure generates unique infrared properties of presented materials and their mixtures.

description: Advancements in irrigation technology have increased water use efficiency. However, producers can be reluctant to convert to a more efficient irrigation system when the initial investment costs are high. This study examines the economic feasibility of replacing low energy precision application (LEPA) center pivot sprinkler irrigation with subsurface drip irrigation (SDI). Specifically, the changes in net investment, variable costs, and total costs related to the conversion of irrigation systems are estimated. Then, these costs are used to evaluate the necessary increase in crop yields with a SDI system under alternative crop scenarios for conversion to be economically feasible.

description: We derive a tensorial formula for a fourth-order conformally invariant differential operator on conformal 4-manifolds. This operator is applied to algebraic Weyl tensor densities of a certain conformal weight, and takes its values in algebraic Weyl tensor densities of another weight. For oriented manifolds, this operator reverses duality: For example in the Riemannian case, it takes self-dual to anti-self-dual tensors and vice versa. We also examine the place that this operator occupies in known results on the classification of conformally invariant operators, and we examine some related operators.

 Aleyrodes (Dialeurodes) Cockerell, 1902: 283. Type species: Aleyrodes citri Ashmead, 1885, by original designation. Dialeurodes Cockerell; as full genus, Quaintance & Baker, 1914: 97.

 Shaninthiae P.M.M. David, 2000: 125 [Synonymised by Martin & Mound, 2007: 28.]
 Comments. Dialeurodes has traditionally been the most speciose whitefly genus. Following a cladistic review by Jensen (1999, 2001), resulting in many species being transferred to Singhiella or Massilieurodes, over 120 described species are still included in Dialeurodes (Martin & Mound, 2007), with Aleuroclava almost equally speciose. Dialeurodes is characterised by the following characters: outline usually oval, margin smooth but tracheal openings at margin always marked by a distinct pore, vasiform orifice very small in comparision with whole puparium, usually subcircular and fully occupied by operculum, with lingula often obscured (Martin, 2005). In Dialeurodes sensu stricto, which includes D. citri, below, the ventral tracheal folds are punctuated by tiny dots or stipples.

description: We study the phenomenology associated to non-minimally coupled dark matter. In particular, we consider the model where the non-minimal coupling arises from the formation of relativistic Bose-Einstein condensates in high density regions of dark matter [1]. This non-minimal coupling is of Horndeski type and leads to a local modification of the speed of gravity with respect to the speed of light. Therefore we can constrain the model by using the joint detection of GW170817 and GRB170817A. We show that the constraints obtained in this way are quite tight, if the dark matter field oscillates freely, whereas they are substantially weakened, if the oscillations are damped by the non-minimal coupling.

description: Weak magnetic fields have recently been detected in a number of A-type stars, including Vega and Sirius. At the same time, space photometry observations of A- and late B-type stars from Kepler and TESS have highlighted the existence of rotational modulation of surface features akin to stellar spots. Here we explore the possibility that surface magnetic spots might be caused by the presence of small envelope convective layers at or just below the stellar surface, caused by recombination of H and He. Using 1D stellar evolution calculations and assuming an equipartition dynamo, we make simple estimates of field strength at the photosphere. For most models the largest effects are caused by a convective layer driven by second helium ionization. While it is difficult to predict the geometry of the magnetic field, we conclude that the majority of intermediate-mass stars should have dynamo-generated magnetic fields of order a few gauss at the surface. These magnetic fields can appear at the surface as bright spots, and cause photometric variability via rotational modulation, which could also be wide-spread in A-stars. The amplitude of surface magnetic fields and their associated photometric variability is expected to decrease with increasing stellar mass and surface temperature, so that magnetic spots and their observational effects should be much harder to detect in late B-type stars.

description: Five three-rings azomethine/ester derivatives, namely, 4-(hexyloxy)phenylazomethine phenyl benzoate (1), 4ʹ-(4”-hexyloxy)phenylazomethine phenyl-3-methoxy benzoate (2), 4ʹ-(4”-hexyloxy)phenylazomethine phenyl-4-methoxy benzoate (3), 4ʹ-(4”-hexyloxy) phenylazomethine phenyl-3,4-dimethoxy benzoate (4), and 4ʹ-(4”-hexyloxy) phenylazomethine phenyl-3,5-dimethoxy benzoate (5), were synthesised and their mesophase behaviour investigated by differential scanning calorimetry (DSC) and polarised optical microscopy (POM). Their molecular structures were elucidated via FT-IR, 1 H-NMR and elemental analysis. All the compounds (1–5) were found to be enantiotropically monomorphic possessing SmA phase with high-temperature range and high thermal stability. Computational studies revealed that all compounds investigated are non-co-planar. The dipole moment of each derivative is a function of the number of the methoxy groups; it decreases in the order 2 ˃ 5 ˃ 1 ˃ 3 > 4. On the other hand, the molecular polarisability is dependent on the number of the methoxy groups, which is accordingly dependent on the molecular aspect ratio. The results of the FMO calculations revealed that the HOMO orbitals energies of the methoxy-substituted compounds 2–5 are lower compared to the laterally neat compound, 1. Finally, the effect of introducing the methoxy group in different position and number affect the charge distribution that could explain the behaviour of the enhanced mesophases.

description: We perform micromagnetic simulations to investigate the propagation of spin-wave beams through spin-wave optical elements. Despite spin-wave propagation in magnetic media being strongly anisotropic, we use axicons to excite spinwave Bessel-Gaussian beams and gradient-index lenses to focus spin waves in analogy to conventional optics with light in isotropic media. Moreover, we demonstrate spin-wave Fourier optics using gradient-index lenses. These results contribute to the growing field of spin-wave optics.

description: Pelvic inflammatory disease (PID) is one of the major public health concerns accounting for 30% of infertility and 50% of ectopic pregnancy cases due to severe inflammation and fibrosis. Punicalagin® are known to exhibit potent anti-inflammatory activity. The aim of this study was to demonstrate the anti-inflammatory and antioxidant effects of Punicalagin®, against pelvic inflammatory disease in rats. Female Sprague Dawley rats (n = 24) were divided into 6 groups (n = 4) as control, PID, prophylactic (low dose and high dose) and therapeutic group (low dose and high dose). PID model was constructed by implanting the rat cervix with mixed microbe (Escherichia Coli and Staphylococcus Aureus) solution. Prophylactic group was gavaged with 3 mg/kg (low dose) and 6 mg/kg (high dose) Punicalagin® daily starting one day before PID induction and therapeutic group was gavaged with 3 mg/kg (low dose) and 6 mg/kg (high dose) Punicalagin® daily starting 1 day after confirmation of PID model. Rats were sacrificed at the end of experiment and samples from upper genital tract were collected for ELISA, antioxidant assay and histopathological examination. According to results, obvious signs of inflammation and oxidative stress including infiltration of neutrophils and significantly raised levels of cytokines, and oxidative stress markers were observed in PID group when compared to control group. Punicalagin® significantly decreased the levels of IL-1β, catalase and lipid peroxidation in both prophylactic and therapeutic groups when compared to PID group. Punicalagin® also decreased the infiltration of leucocytes in uterus of prophylactic and therapeutic group when compared to PID group, as determined by histological examination. On basis of these results, we concluded that Punicalagin® showed anti-inflammatory and antioxidant potential in rat model of pelvic inflammatory disease and could be used as possible therapeutic agent in treatment of PID.

description: The random phase approximation (RPA) builds in correlations left out by mean-field theory. In full 0-hbar-omega shell-model spaces we calculate the Hartree-Fock + RPA binding energy, and compare it to exact diagonalization. We find that in general HF+RPA gives a very good approximation to the ``exact'' ground state energy. In those cases where RPA is less satisfactory, however, there is no obvious correlation with properties of the HF state, such as deformation or overlap with the exact ground state wavefunction.

description: Goals are first-class entities in a self-adaptive system (SAS) as they guide the self-adaptation. A SAS often operates in dynamic and partially unknown environments, which cause uncertainty that the SAS has to address to achieve its goals. Moreover, besides the environment, other classes of uncertainty have been identified. However, these various classes and their sources are not systematically addressed by current approaches throughout the life cycle of the SAS. In general, uncertainty typically makes the assurance provision of SAS goals exclusively at design time not viable. This calls for an assurance process that spans the whole life cycle of the SAS. In this work, we propose a goal-oriented assurance process that supports taming different sources (within different classes) of uncertainty from defining the goals at design time to performing self-adaptation at runtime. Based on a goal model augmented with uncertainty annotations, we automatically generate parametric symbolic formulae with parameterized uncertainties at design time using symbolic model checking. These formulae and the goal model guide the synthesis of adaptation policies by engineers. At runtime, the generated formulae are evaluated to resolve the uncertainty and to steer the self-adaptation using the policies. In this paper, we focus on reliability and cost properties, for which we evaluate our approach on the Body Sensor Network (BSN) implemented in OpenDaVINCI. The results of the validation are promising and show that our approach is able to systematically tame multiple classes of uncertainty, and that it is effective and efficient in providing assurances for the goals of self-adaptive systems.

description: This study examines the economic potential of harvesting cellulosic biomass from corn and three types of sorghum rotated with soybeans using enterprise budgets constructed with experiment field data. The results show that harvesting of crop residue from grain sorghum, corn, and biomass from an energy sorghum that does not produce grain is economically feasible. Net returns from corn that produced grain and corn stover has the highest net return per acre. Dual purpose sorghum which produces sorghum grain and sorghum stover has the second highest net return per acre. Net returns from the other two sorghums were substantially less.

description: The ability of operators and managers to benchmark farm performance with those in their region is a great starting point for cost management. This study expands on the traditional one-tier stratification of farm-level data and uses a two-tier approach using farm income and expense allocation as categories of performance. Farm managers, consultants, and landowners can utilize this framework to provide more insights and management opportunities for their self or their clientele. More specifically, they can identify expenditure characteristics and the capital allocation of the top managers for benchmarking against their own operations.

description: We consider a two dimensional (2D) model of particles interacting in a Landau level. We work in a finite disk geometry and take the particles to interact with a linearly decreasing two-body Haldane pseudo-potential. We show that the ground state subspace of this model is spanned by the wave-functions that can be written as polynomial conformal blocks (of an arbitrary conformal field theory) consistent with the filling fraction (scaling dimension). To remove degeneracies, we then add a quadratic perturbation to the Hamiltonian and show that; 1. Conformal blocks constructed using the Moore-Read construction (e.g. Laughlin, Pfaffian, and Read-Rezayi states) remain exact eigenstates of this model in the thermodynamic limit and 2. By tuning an externally imposed single-body $-L_z^2$ potential we can enforce Moore-Read conformal blocks to become exact ground states of this model in the thermodynamic limit. We cannot rule out the possibility of residual degeneracies in this limit. This model has no filling dependence and is comprised only from two-body long-range interactions and external single-body potentials. Our results provide insight into how conformal block wave-functions can emerge in a Landau level.

description: In the United States, meat goat production has increased as the demand for goat meat has expanded due to immigration from Central and South America, Africa, Asia, and the Middle- East. Mail survey data were collected from US meat goat farmers during the summer of 2012, to examine the current status of US meat goat farms. Results obtained from the survey provide a snapshot into meat goat farmers’ adoption of technology, management practices, and production systems in the United States.

description: The main objectives of this study are to evaluate the impact of irrigation water use efficiency improvement on enhancing the value of water used for irrigation; and to estimate the potential for private water cost reductions in irrigated durum wheat production systems of semi-arid Tunisia. Data Envelopment Analysis and stochastic frontier methods were combined for this aim. Results show that significant inefficiencies exist in the farm sample under investigation. We also show that increasing irrigation water use efficiency could shift the curve of marginal water value upwards, thereby indicating a rising of water value. By operating at full water economic efficiency level, farms would be able to reduce water costs for wheat production by about 42%, in average. We conclude that there is a wide scope to improve water use efficiency in the study area, allowing for a better valuation of the water resources used for the irrigation.
A Decade in the Life of EXO 2030+375: A Multi-wavelength Study of an Accreting X-ray Pulsar

description: Using BATSE and RXTE observations from 1991 April to 2001 August we have detected 71 outbursts from 82 periastron passages of EXO 2030+375, a 42-second transient X-ray pulsar with a Be star companion, including several outbursts from 1993 August to 1996 April when the source was previously believed to be quiescent. Combining BATSE, RXTE, and EXOSAT data we have derived an improved orbital solution. Applying this solution results in a smooth profile for the spin-up rate during the giant outburst and results in evidence for a correlation between the spin-up rate and observed flux in the brighter BATSE outbursts. Infrared and Halpha measurements show a decline in the density of the circumstellar disk around the Be star. This decline is followed by a sudden drop in the X-ray flux and a turn-over from a spin-up trend to spin-down in the frequency history. This is the first Be/X-ray binary which shows an extended interval, about 2.5 years, where the global trend is spin-down, but the outbursts continue. In 1995 the orbital phase of EXO 2030+375's outbursts shifted from peaking about 6 days after periastron to peaking before periastron. The outburst phase slowly recovered to peaking at about 2.5 days after periastron. We interpret this shift in orbital phase followed by a slow recovery as evidence for a global one-armed oscillation propagating in the Be disk. This is further supported by changes in the shape of the Halpha profile which are commonly believed to be produced by a reconfiguration of the Be disk. The truncated viscous decretion disk model provides an explanation for the long series of normal outbursts and the evidence for an accretion disk in the brighter normal outbursts.

description: This study aimed to investigate the incentive/disincentive impacts of social grants on the proportion of land area cultivated by rural households. The study relied on a sample of 984 households from KwaZulu-Natal (KZN), South Africa. The results showed no association between social grants and proportion of land area cultivated by farmers. This has two implications. Firstly, it suggests that the disincentive hypothesis should not be accepted. Secondly, it implies that the potential complementarity between social grants and smallholder farming has not materialised. Given that social grants are now seen as strategies to promote rural livelihoods in South Africa, the study recommends that the objectives of social grants and smallholder farming be synchronised so that the potential complementarity between the two interventions may materialise. The study identified several other constraints that policy makers should focus on to increase the proportion of land area cultivated by smallholder farmers.

description: Two series of Schiff bases liquid crystals with electronically different terminal substituents, 4-(alkoxy)phenylimino)methyl)benzonitrile (In-a) and N-(4-(hexyloxy)benzylidene)-4-(alkoxy)benzenamine (In-6), were synthesise. Their molecular geometries were elucidated via FT-IR, 1 H-NMR and elemental analysis. Mesomorphic and optical properties were investigated by differential scanning calorimetry (DSC) and polarised optical microscopy (POM). The effect of electronic nature of in the attached terminals, extra-conjugation E- withdrawing (CN) and E-donating (hexyloxy), is investigated. All members of the investigated compounds were enantiotropically mesomorphic comprising mono or dimorphic phases depending on the electronic and complexity nature of attached terminals. Computational parameters of both series were related with the experimental findings of the mesophase stability and the length of alkoxy chains to investigate the effect of the terminals on the stability of possible architectures. Density functional theory (DFT) calculations revealed that all investigated members are non-co-planar with twist angles between the rings around the CH = N linkage. The relations of the experimentally mesophase range and stability of the enhanced phases with simulated parameters were studied to conclude that these factors contributed in different extent to affect the mesomorphic behaviour. The binary phase diagrams were constructed between In-6 components and achieved very low melting temperatures at their eutectic mixtures.

description: Simultaneous real-time fMRI and EEG neurofeedback (rtfMRI-EEG-nf) is an emerging neuromodulation approach, that enables simultaneous volitional regulation of both hemodynamic (BOLD fMRI) and electrophysiological (EEG) brain activities. Here we report the first application of rtfMRI-EEG-nf for emotion self-regulation training in patients with major depressive disorder (MDD). In this proof-of-concept study, MDD patients in the experimental group (n=16) used rtfMRI-EEG-nf during a happy emotion induction task to simultaneously upregulate two fMRI and two EEG activity measures relevant to MDD. The target measures included BOLD activities of the left amygdala (LA) and left rostral anterior cingulate cortex (rACC), and frontal EEG asymmetries in the alpha band (FAA, [7.5-12.5] Hz) and high-beta band (FBA, [21-30] Hz). MDD patients in the control group (n=8) were provided with sham feedback signals. An advanced procedure for improved real-time EEG-fMRI artifact correction was implemented. The experimental group participants demonstrated significant upregulation of the LA BOLD activity, FAA, and FBA during the rtfMRI-EEG-nf task, as well as significant enhancement in fMRI connectivity between the LA and left rACC. Average individual FAA changes during the rtfMRI-EEG-nf task positively correlated with depression and anhedonia severities, and negatively correlated with after-vs-before changes in depressed mood ratings. Temporal correlations between the FAA and FBA time courses and the LA BOLD activity were significantly enhanced during the rtfMRI-EEG-nf task. The experimental group participants reported significant mood improvements after the training. Our results suggest that the rtfMRI-EEG-nf may have potential for treatment of MDD.

description: In this paper, we adapt the geodesic distance-based recursive filter to the sparse data interpolation problem. The proposed technique is general and can be easily applied to any kind of sparse data. We demonstrate the superiority over other interpolation techniques in three experiments for qualitative and quantitative evaluation. In addition, we compare our method with the popular interpolation algorithm presented in the EpicFlow optical flow paper that is intuitively motivated by a similar geodesic distance principle. The comparison shows that our algorithm is more accurate and considerably faster than the EpicFlow interpolation technique.
