description: This paper describes how representative farm business models were employed to identify optimal beef and sheep production systems for Less Favoured Area (LFA) farms in Northern Ireland. The bio-economic models identify the optimal farming system for theses farms under various market and policy assumptions. They are useful, therefore, in helping to develop industry strategy. The models indicate that, under current market and policy conditions, a dairy-based beef system is likely to be the most profitable beef enterprise. However, depending on land quality and livestock housing resources, and the market and policy environment, suckler-based beef systems can also feature in the profit maximising enterprise mix. The results also suggest that the optimal sheep system is consistent with the stratified sheep systems traditionally operated in Northern Ireland. In general, beef production appears to have some advantages over sheep production where, depending on relative prices and resource availabilities, it is often better to replace sheep with cattle and employ the released labour off-farm, than to replace cattle with sheep and invest the released capital off-farm. In some situations, farmers should significantly reduce their capital and labour inputs to the farm business by substantially reducing stocking rates or even abandoning land completely

description: In this study, we report identification of a new ultraluminous X-ray source (ULX) named as X-7 in NGC 1316, with an unabsorbed luminosity of 2.1$\times$10$^{39}$ erg s$^{-1}$ using the two recent Chandra archival observations. The X-7 was detected in the Chandra 2001 observation and was included in the source list of the NGC 1316 as CXOUJ032240.8-371224 with a luminosity of 5.7$\times$10$^{38}$ erg s$^{-1}$. Present luminosity implies a luminosity increase of a factor of $\sim$ 4. The best fit spectral model parameters indicate that X-7 has a relatively hot disk and hard spectra. If explained by a diskblackbody model, the mass of compact object is estimated as $\sim$ 8 M$\odot$ which is in the range of a stellar-mass black hole. The X-7 shows a relatively long-term count rate variability while no short-term variability is observed. We also identified a unique optical candidate within 0.22" error circle at 95\% confidence level for X-7 using the archival HST/ACS and HST/WFC3 data. Absolute magnitude (M$_{V}$) of this candidate is -7.8 mag. Its spectral energy distribution is adequately fitted a blackbody model with a temperature of 3100 K indicating an M type supergiant, assuming the donor star dominates the optical emission. In addition, we identified a transient ULX candidate (XT-1) located 6" away from X-7 has a (high) luminosity of $\sim$ 10$^{39}$ erg s$^{-1}$ with no visible optical candidate.

description: A research program has been started to study experimentally the near-threshold photodissociation of nuclides in the chain of cosmic heavy element production with bremsstrahlung from the ELBE accelerator. An important prerequisite for such studies is good knowledge of the bremsstrahlung distribution which was determined by measuring the photodissociation of the deuteron and by comparison with model calculations. First data were obtained for the astrophysically important target nucleus 92-Mo by observing the radioactive decay of the nuclides produced by bremsstrahlung irradiation at end-point energies between 11.8 MeV and 14.0 MeV. The results are compared to recent statistical model calculations.

description: Modern theories of sales make conflicting predictions about the temporal pattern of sales, which we test using retail chain level data. In this paper, we focus on the retail sale patterns of two retail milk prices in a New Member State (NMS), Hungary using weekly data across eight retail chain between 2005 January and 2008 June. We employ a battery of empirical tests, to try a number of sale theory hypotheses. First, we present summary statistics, histograms, and correlations of prices and sales from which we conclude that no theory of sales fully describes sale patterns and price distributions. Second, we apply vector autoregressive analysis and Granger tests of temporal ordering (”causality tests”) to determine whether the sale of one retail chain is followed in a predictable way by the sale of another retail chain or its own later sales. Our results suggest a dual retail market structure. Finally, we employ panel cointegration to test confirm that durable goods should have qualitatively different pricing pattern than less-durable goods. Similarly to Berck et al. (2007) we fail to see a clear difference between storable milk and boxed milk patterns.

description: Photoelectron angular distributions (PADs), ranging up to the maximum 6th order Legendre polynomial term set by the Yang theorem, have been recorded for the (2 + 1) resonance enhanced multiphoton ionization (REMPI) of two terpene isomers, 3-carene and α-pinene, employing femtosecond lasers and electron velocity map imaging detection. PAD measurements made with coincident photoion detection allow ion fragmentation effects to be assessed. Using circular polarization and enantiomerically pure samples the PAD measurements are extended to include chiral (odd) Legendre polynomial terms, and these are analysed and discussed as multiphoton photoelectron circular dichroism (MP-PECD). Comparisons are also made with single photon (synchrotron radiation) PECD of these compounds. Although for a given compound a common final cation state is reached, pronounced differences are observed between PECD and MP-PECD, and between the alternative identified REMPI intermediate states in the case of MP-PECD.
Angular momentum and the geometrical gauge of localized photon staes

description: Localized photon states have non-zero angular momentum that varies with the non-unique choice of a transverse basis and is changed by gauge transformations of the geometric vector potential $\mathbf{a}$. The position operator must depend on the choice of gauge, but a complete gauge transformation of a physically distinct state has no observable effects. The potential $\mathbf{a}$ has a Dirac string singularity that is related to an optical vortex of the electric field.

description: A single-photon CMOS image sensor design based on pinned photodiode (PPD) with multiple charge transfers and sampling is described. In the proposed pixel architecture, the photogenerated signal is sampled non-destructively multiple times and the results are averaged. Each signal measurement is statistically independent and by averaging the electronic readout noise is reduced to a level where single photons can be distinguished reliably. A pixel design using this method has been simulated in TCAD and several layouts have been generated for a 180 nm CMOS image sensor process. Using simulations, the noise performance of the pixel has been determined as a function of the number of samples, sense node capacitance, sampling rate, and transistor characteristics. The strengths and the limitations of the proposed design are discussed in detail, including the trade-off between noise performance and readout rate and the impact of charge transfer inefficiency. The projected performance of our first prototype device indicates that single-photon imaging is within reach and could enable ground-breaking performance in many scientific and industrial imaging applications.

description: Traceability is helping retailers manage food safety risks and support product differentiation. This paper aims to investigate how traceability may be used to screen supplier for private labels dedicated provider pools. Retailers in the UK and Italy have several private label product lines and increasingly select dedicated suppliers. The choice of providers is a typical agency problem as retailers contract the production for their private labels, having incomplete information on types and effort of their suppliers. Different contracts must be designed for suppliers of private labels depending on position of the product line and its food safety risk. A case study, based on the second largest Italian retailer reveals that traceability and quality assurance schemes are used together to manage suppliers of private labels

description: Recently, there has been much attention devoted to resolving the quantum corrections to the Bekenstein--Hawking (black hole) entropy. In particular, many researchers have expressed a vested interest in fixing the coefficient of the sub-leading logarithmic term. In the current paper, we are able to make some substantial progress in this direction by utilizing the generalized uncertainty principle (GUP). Notably, the GUP reduces to the conventional Heisenberg relation in situations of weak gravity but transcends it when gravitational effects can no longer be ignored. Ultimately, we formulate the quantum-corrected entropy in terms of an expansion that is consistent with all previous findings. Moreover, we demonstrate that the logarithmic prefactor (indeed, any coefficient of the expansion) can be expressed in terms of a single parameter that should be determinable via the fundamental theory.

Based on an understanding farmer decision-making, the I3 Response Framework can help identify strategies that can strongly influence compliance, providing more efficient targeting of resources for policy. We report on further testing by application to the issue of water quality and the regulations around slurry storage as part of the Nitrate Pollution Prevention Regulations 2008 as applicable to dairy farmers in the Derwent catchment of North Yorkshire, England

description: The direction dependence of the event rate in WIMP direct detection experiments provides a powerful tool for distinguishing WIMP events from potential backgrounds. We use a variety of (non-parametric) statistical tests to examine the number of events required to distinguish a WIMP signal from an isotropic background when the uncertainty in the reconstruction of the nuclear recoil direction is included in the calculation of the expected signal. We consider a range of models for the Milky Way halo, and also study rotational symmetry tests aimed at detecting non-sphericity/isotropy of the Milky Way halo. Finally we examine ways of detecting tidal streams of WIMPs. We find that if the senses of the recoils are known then of order ten events will be sufficient to distinguish a WIMP signal from an isotropic background for all of the halo models considered, with the uncertainties in reconstructing the recoil direction only mildly increasing the required number of events. If the senses of the recoils are not known the number of events required is an order of magnitude larger, with a large variation between halo models, and the recoil resolution is now an important factor. The rotational symmetry tests require of order a thousand events to distinguish between spherical and significantly triaxial halos, however a deviation of the peak recoil direction from the direction of the solar motion due to a tidal stream could be detected with of order a hundred events, regardless of whether the sense of the recoils is known.

description: The climatic controls on the stable carbon isotopic composition (d13C) of speleothem carbonate are less often discussed in the scientific literature in contrast to the frequently used stable oxygen isotopes. Various local processes influence speleothem d13C values and confident and detailed interpretations of this proxy are often complex. A better understanding of speleothem d13C values is critical to improving the amount of information that can be gained from existing and future records. This contribution aims to disentangle the various processes governing speleothem d13C values and assess their relative importance. Using a large data set of previously published records we examine the spatial imprint of climate-related processes in speleothem d13C values deposited post-1900 CE, a period during which global temperature and climate data is readily available. Additionally, we investigate the causes for differences in average d13C values and growth rate under identical climatic conditions by analysing pairs of contemporaneously deposited speleothems from the same caves. This approach allows to focus on carbonate dissolution and fractionation processes during carbonate precipitation, which we evaluate using existing geochemical models. Our analysis of a large global data set of records reveals evidence for a temperature control, likely driven by vegetation and soil processes, on d13C values in recently deposited speleothems. Moreover, data-model intercomparison shows that calcite precipitation occurring along water flow paths prior to reaching the top of the speleothem can explain the wide d13C range observed for concurrently deposited samples from the same cave. We demonstrate that using the combined information of contemporaneously growing speleothems is a powerful tool to decipher controls on d13C values ...

description: We have measured the two-photon EF←X (v″=3−9) Resonance-Enhanced Multiphoton Ionization (REMPI) spectrum of H2 by producing the hydrogen molecule via photolysis of H2CO. H2 is produced with rovibrational energies up to 30,000 cm−1, at a maximum observed (v″,J″) of (9,5). In the well-resolved jet-cooled H2CO spectrum, ortho and para H2 are selectively produced with near 100% selectivity. Over 470 REMPI transitions were identified in the EF−X band system, many of which have not been seen previously, including transitions to EF levels not yet accurately measured. Speed distributions were obtained for each REMPI transition using Velocity-mapped imaging, aiding in the assignment by providing a precise measurement of the internal energy of the H2 molecule.

Magnesium modulates cellular ROS levels to control cytoskeletal remodeling
Creators: name: Al-Saadi, Namariq Hadi
Publisher: name: No Publisher Supplied
Year: 2021

description: Evidence for putative second messenger functions for Mg2+ has quietly accumulated for decades. Bound to DNA, RNA, and ATP and functioning as a cofactor for over 600 different enzymes, an enduring mystery is how signal discrimination is achieved when Mg2+ is the second most abundant cation in the cell. We previously showed that depletion of the TRPM7 ion channel from fibroblasts reduces intracellular Mg2+, interfering with the actin cytoskeleton's remodeling during polarized cell movements. Defects in cell spreading and formation of actin stress fibers caused by loss of the channel can be rescued by overexpression of the magnesium transporter SLC41A2. Here we report that Mg2+ controls remodeling of the actin cytoskeleton independent of microtubules by regulating the concentration of reactive oxygen species (ROS) in cells. A lowering of ROS levels accompanies a reduction in cellular Mg2+ caused by depletion of the TRPM7 ion channel. Raising ROS levels independent of Mg2+ rescued defects in cell spreading caused by depletion of the channel. To test whether Mg2+ acts independent of TRPM7 to regulate the actin cytoskeleton we overexpressed the Mg2+ exporter CNNM2 in fibroblasts to lower intracellular Mg2+, which we found also lowered ROS levels and produced similar defects in the cellular distribution of actin but not microtubules similar to that observed for cellular depletion of TRPM7. Reducing ROS levels independent of changes in cellular Mg2+ by overexpression of the ROS scavenger catalase produced similar changes in the cytoskeleton and cell morphology. Mg2+-dependent changes in cellular ROS results in the oxidation of numerous proteins, including those involved in cytoskeletal remodeling. We conclude that signal transduction via changes in intracellular Mg2+ signals occur by Mg2+-dependent changes in cellular ROS levels.

description: With the latest reform of EU Structural Policy, the Highlands and Islands have been excluded from further support by Structural Funds beyond 2013, but the new Scottish Rural Development Programme has increased CAP Pillar 2 expenditures in Scotland. A modified version of a system dynamics model constructed for an EU-wide case-study project (TOP-MARD) was used to simulate the effects of these and other policy changes in Caithness and Sutherland (C&S), a remote rural area in Northern Scotland. Several alternative modelling scenarios were developed, mostly relating to reconfigurations of Pillar 2 spending within the area. The modelling results, i.e. projections from 2001 to 2021, are discussed in terms of agricultural employment, regional population, and economic trends. It is shown that by targeting Pillar 2 money to non-agricultural rural development measures instead of to farm investments, less favoured area or agrienvironmental schemes, the long-term trends in severe depopulation, ageing and deindustrialisation in the area can be alleviated but not avoided. Finally, some conclusions are drawn, both about the implications of the results for sustainability in C&S, and in general for future sustainable rural development policy.

description: This study examines the influences of economic and non-economic variables on the size of U.S. sow breeding operations using a probit model. Data from a national survey of U.S. hog operations identifying two different size categories were used in this study. Findings indicate that factors such as operations located in Delta States, climate controlled facilities, specialized operation, breeding practices, and risk attitudes toward investments influence decisions to establish breeding operations with 500 or more sows. Producers located in Iowa were more likely to choose breeding operations with 499 or less sows.

description: In marine management, fish stocks are often managed on a stock-by-stock basis using single-species models. Many of these models are based upon statistical techniques and are good at assessing the current state and making short-term predictions; however, as they do not model interactions between stocks, they lack predictive power on longer timescales. Additionally, there are mechanistic multi-species models that represent key biological processes and consider interactions between stocks such as predation and competition for resources. Due to the complexity of these models, they are difficult to fit to data, and so many mechanistic multi-species models depend upon single-species models where they exist, or ad hoc assumptions when they don't, for parameters such as annual fishing mortality. In this paper we demonstrate that by taking a state-space approach, many of the uncertain parameters can be treated dynamically, allowing us to fit, with quantifiable uncertainty, mechanistic multi-species models directly to data. We demonstrate this by fitting uncertain parameters, including annual fishing mortality, of a size-based multi-species model of the Celtic Sea, for species with and without single-species stock-assessments. Consequently, errors in the single-species models no longer propagate through the multi-species model and underlying assumptions are more transparent. Building mechanistic multi-species models that are internally consistent, with quantifiable uncertainty, will improve their credibility and utility for management. This may lead to their uptake by being either used to corroborate single-species models; directly in the advice process to make predictions into the future; or used to provide a new way of managing data-limited stocks.

description: We investigate Anderson localization of two particles moving in a two-dimensional (2D) disordered lattice and coupled by contact interactions. Based on transmission-amplitude calculations for relatively large strip-shaped grids, we find that all pair states are localized in lattices of infinite size. In particular, we show that previous claims of an interaction-induced mobility edge are biased by severe finite-size effects. The localization length of a pair with zero total energy exhibits a nonmonotonic behavior as a function of the interaction strength, characterized by an exponential enhancement in the weakly interacting regime. Our findings also suggest that the many-body mobility edge of the 2D Anderson-Hubbard model disappears in the zero-density limit, irrespective of the (bosonic or fermionic) quantum statistics of the particles.

On the stellar populations in NGC 185 and NGC 205, and the nuclear star cluster in NGC 205 from Hubble Space Telescope observations

description: [Abridged] We present a first detailed analysis of resolved stellar populations in the dwarf galaxies NGC 185 and NGC 205 based on archival V- and I-band WFPC2 pointings. For NGC 185 we deduce that star formation was probably still active about 4 x 10^8 yr ago. Key abundance-related results are: (1) We identify ancient stars with [Fe/H] -1.11 +/- 0.08 dex for ancient stars. For NGC 205, we record (m-M)o = 24.76 +/- 0.1 mag, based on the RGB I-band tip magnitude method. We find that stars were probably still forming less than 3 x 10^8 yr ago, which is compatible with star formation triggered by an interaction with M31. Key abundance-related results are: (1) The RGB/ faint-AGB is significantly skewed to redder values than that of a control field in the outskirts of M31; it probably results from a relatively narrow metallicity and or age range for a significant fraction of the dwarf's stars. (2) For ancient stars we infer from colour information that the median [Fe/H] > -1.06+/-0.04 dex. We briefly compare the stellar populations of NGC 205, NGC 185 and NGC 147. Finally, we find an apparent blue excess in the outer region of the nuclear star cluster in NGC 205. It is as compact as a typical galactic globular cluster, but is quite bright (10^6 L_solar,R); and by matching its blue colour with models, its stellar population is young, up to a few times 10^8 yr old.

Dynamic Model of Super-Arrhenius Relaxation Rates in Glassy Materials

description: We propose that the super-Arrhenius relaxation rates observed in glassy materials are determined by thermally nucleated rearrangements of increasing numbers of molecules at decreasing temperatures. In our model of this mechanism, string-like fluctuations in the neighborhood of shear transformation zones (STZ's) provide routes along which rearrangements can propagate, and the entropy associated with long enough strings allows the rearrangement energy to be distributed stably in the surrounding material. We further postulate that, at low enough temperatures, these fluctuations are localized on the interfaces between frustration-limited domains. Our result is a modified Vogel-Fulcher formula at low temperatures that crosses over to a simple Arrhenius law as the glass changes from being solid-like to liquid-like. To achieve agreement with experiment in the crossover region, we need to make what seem to us to be overly strong assumptions about the behavior of frustration-limited domains.

description: This doctoral thesis studies the spatial market efficiency of wheat markets in selected post-Soviet countries; particularly in Russia, the largest wheat exporting country in the world, and in the grain import-dependent countries of Central Asia and the South Caucasus. Increased grain production in the Black Sea region, and in Russia specifically, is crucial for meeting increasing global agricultural demand and global food security. Grain production in Russia could be boosted by increasing grain production efficiency and also by re-cultivating formerly abandoned agricultural land. However, to increase Russia's role in global wheat supply, additional grain production potential has to coincide with improving the country's grain export perspectives. On the other hand, the realization of Russia's export capacity largely depends on the performance of its regional grain markets domestically. Using price transmission and panel data analyses in a comparative context, this study finds the wheat market of Russia segmented, with the primary wheat export region poorly integrated into the domestic market. This thesis also demonstrates that regional wheat market integration in Russia is relatively low and heterogeneous and trade costs are relatively high compared to the USA, mostly due to large distances between grain producing regions. In addition, by including the USA as benchmark country, a comparative approach enables a more comprehensive assessment of the spatial market efficiency of the wheat market in Russia. The results also provide evidence on the dissimilarity of the underlying fundamental mechanism of market integration between Russia and the USA. In Russia, the physical trade of wheat mainly fosters market integration at the interregional level, whereas in the USA, in addition to physical trade, information flows induced by commodity futures markets play a major role in the regional grain market integration.

description: Diluted magnetic semiconductors (DMSs) based on group-IV materials are desirable for spintronic devices compatible with current silicon technology. In this work, amorphous Mn-doped SiGe thin films were first fabricated on Ge substrates by radio frequency magnetron sputtering and then crystallized by rapid thermal annealing (RTA). After the RTA, the samples became ferromagnetic (FM) semiconductors, in which the Curie temperature increased with increasing Mn doping concentration and reached 280 K with 5% Mn concentration. The data suggest that the ferromagnetism came from the hole-mediated process and was enhanced by the tensile strain in the SiGe crystals. Meanwhile, the Hall effect measurement up to 33 T to eliminate the influence of anomalous Hall effect (AHE) reveals that the hole mobility of the annealed samples was greatly enhanced and the maximal value was ~1000 cm2/Vs, owing to the tensile strain-induced band structure modulation. The Mn-doped SiGe thin films with high Curie temperature ferromagnetism and high hole mobility may provide a promising platform for semiconductor spintronics.

description: Mississippi is largely agricultural with access to many watersheds, the combination of which makes the state attractive to hunters and fishermen. This paper investigates the impact of hunting/fishing on the sales tax revenue in the counties of Mississippi. Our results indicate that a 1% increase in the non-resident hunting/fishing license sold increases tax revenue by $14,535.65 per county on average.
