Temperature correction to the Casimir force in cryogenic range and anomalous skin effect

description: Temperature correction to the Casimir force is considered for real metals at low temperatures. With the temperature decrease the mean free path for electrons becomes larger than the field penetration depth. In this condition description of metals with the impedance of anomalous skin effect is shown to be more appropriate than with the permittivity. The effect is crucial for the temperature correction. It is demonstrated that in the zero frequency limit the reflection coefficients should coincide with those of ideal metal if we demand the entropy to be zero at T=0. All the other prescriptions discussed in the literature for the $n=0$ term in the Lifshitz formula give negative entropy. It is shown that the temperature correction in the region of anomalous skin effect is not suppressed as it happens in the plasma model. This correction will be important in the future cryogenic measurements of the Casimir force.

description: We study the emergence of glassy states after a sudden cooling in lattice models with short range interactions and without any a priori quenched disorder. The glassy state emerges whenever the equilibrium model possesses a sufficient number of coexisting crystalline phases at low temperatures, provided the thermodynamic limit be taken before the infinite time limit. This result is obtained through simulations of the time relaxation of the standard Potts model and some exclusion models equipped with a local stochastic dynamics on a square lattice.

description: Here we report the effect of structural and superconductivity properties on Ru doped CuIr2Te4 telluride chalcogenide. XRD results suggest that the CuIr2-xRuxTe4 maintain the disordered trigonal structure with space group P3m1 (No. 164) for x less than 0.3. The lattice constants, a and c, both decrease with increasing Ru content. Temperature-dependent resistivity, magnetic susceptibility and specific-heat measurements are performed to characterize the superconducting properties systematically. Our results suggest that the optimal doping level for superconductivity in CuIr2-xRuxTe4 is x = 0.05, where Tc is 2.79 K with the Sommerfeld constant gamma of 11.52 mJ mol-1 K-2 and the specific-heat anomaly at the superconducting transition, is approximately 1.51, which is higher than the BCS value of 1.43, indicating CuIr1.95Ru0.05Te4 is a strongly electron-phonon coupled superconductor. The values of lower critical filed and upper critical field calculated from isothermal magnetization and magneto-transport measurements are 0.98 KOe and 2.47 KOe respectively, signifying that the compound is clearly a type-II superconductor. Finally, a dome-like shape superconducting Tcs vs. x content phase diagram is established, where the charge density wave disappears at x = 0.03 while superconducting transition temperature (Tc) rises until it reaches its peak at x = 0.05, then, with decreasing when x reaches 0.3. This feature of the competition between CDW and the superconductivity could be caused by tuning the Fermi surface and density of states with Ru chemical doping.

description: The experimentally determined Sagnac fringe shift dependency on angular velocity and enclosed area is derived from the rotating reference frame using non-time-orthogonal tensor analysis. The relationship for the most general case, in which the area enclosed is not circular and does not have the axis of rotation passing through its center, is determined. It is submitted that this quantitative result, along with a related thought experiment, can not be found using the conventional approach of local co-moving Lorentz frames.

description: We compute spectra, waveforms, angular distribution and total gravitational energy of the gravitiational radiation emitted during the radial infall of a massless particle into a Schwarzschild black hole. Our fully relativistic approach shows that (i) less than 50% of the total energy radiated to infinity is carried by quadrupole waves, (ii) the spectra is flat, and (iii) the zero frequency limit agrees extremely well with a prediction by Smarr. This process may be looked at as the limiting case of collisions between massive particles traveling at nearly the speed of light, by identifying the energy $E$ of the massless particle with $m_0 γ$, $m_0$ being the mass of the test particle and $γ$ the Lorentz boost parameter. We comment on the implications for the two black hole collision at nearly the speed of light process, where we obtain a 13.3% wave generation efficiency, and compare our results with previous results by D'Eath and Payne.

description: We construct the non-compact Calabi-Yau manifolds interpreted as the complex line bundles over the Hermitian symmetric spaces. These manifolds are the various generalizations of the complex line bundle over CP^{N-1}. Imposing an F-term constraint on the line bundle over CP^{N-1}, we obtain the line bundle over the complex quadric surface Q^{N-2}. On the other hand, when we promote the U(1) gauge symmetry in CP^{N-1} to the non-abelian gauge group U(M), the line bundle over the Grassmann manifold is obtained. We construct the non-compact Calabi-Yau manifolds with isometries of exceptional groups, which we have not discussed in the previous papers. Each of these manifolds contains the resolution parameter which controls the size of the base manifold, and the conical singularity appears when the parameter vanishes.

Meta-Analysis

description: Instructional materials in science education from primary school to graduate level are typically
written as expository texts. Instead, narratives are only rarely chosen to teach scientific concepts,
likely due to the inconclusive evidence regarding the effectiveness of narrative interventions.
This meta-analysis synthesizes the results of 30 empirical studies with 72 independent effect
sizes representing the academic performance of over 5300 students when learning with either
narrative or expository materials. The narrative learning materials had significant and positive
effect on performance (g = 0.16; 95% CI: 0.03-0.30, p < .05) but indicated high between-study
heterogeneity (I2 = 79%; 95% CI: 75-83%). Follow-up moderator analyses revealed that learning
from personal or scientist-centered stories was more favorable than learning from fictional
stories. The findings were robust across different education levels. Furthermore, the results
indicated that narratives were especially favorable in supporting understanding and more
impactful in formal than informal educational settings.

description: The role producer risk preferences on WTP is for sustainable breeding practices addressed in this paper using stated preference methods. Estimates of WTP amongst beef producers are compared with those the diary sector. Whilst preliminary indicate a relatively lower impact, these effects seem nuanced in dairy relative to beef. This suggests that influence of risk in the producer valuation of new technologies may be commingled with market structure effects.

description: We have performed a detailed study of thermal annealing of the moment configuration in artificial spin ice. Permalloy (Ni$_{80}$Fe$_{20}$) artificial spin ice samples were examined in the prototypical square ice geometry, studying annealing as a function of island thickness, island shape, and annealing temperature and duration. We also measured the Curie temperature as a function of film thickness, finding that thickness has a strong effect on the Curie temperature in regimes of relevance to many studies of the dynamics of artificial spin ice systems. Increasing the interaction energy between island moments and reducing the energy barrier to flipping the island moments allows the system to more closely approach the collective low energy state of the moments upon annealing, suggesting new channels for understanding the thermalization processes in these important model systems.

description: The purpose of this study is to develop a model that calculates the probability distribution of camelina expected yields dependent on location-related variables such as precipitation, temperature, and solar radiation, as well as nitrogen rate and others. Camelina is an oilseed crop grown in cool climate with low input requirements including little water. The application to camelina addresses challenges in analysis of potential adoption of crops with limited field data. Our data include trials and crop yields in the United States from 2005 to 2012. They have been assembled from various published reports covering a range of locations, seasons, and production methods. We begin by fitting a least squares (LS) regression model to camelina yields. As a robustness check we also apply a stochastic frontier framework under Cobb-Douglas technology. Preliminary results indicate that the average maximum precipitation for the period of interest positively affected the mean camelina yields, whereas it has no impact on yield variability. An increase in average maximum precipitation will more likely decrease the technical inefficiency. Both higher nitrogen rates and higher average maximum growing degree days will more likely increase the average yields. A taller camelina plant positively affects the mean yields and the yield variability. In contrast, total solar radiation is negatively correlated with mean yields and variation. There is still much to be learned about the crop and its best management practices as production expands. The analysis of the interaction of managed input variables and environmental factors will help us assess varietal performance and provide location conditional predictions.

description: We present a composite pulse controlled phase gate which together with a bus architecture improves the feasibility of a recent quantum computing proposal based on rare-earth-ion doped crystals. Our proposed gate operation is tolerant to variations between ions of coupling strengths, pulse lengths, and frequency shifts, and it achieves worst case fidelities above 0.999 with relative variations in coupling strength as high as 10% and frequency shifts up to several percent of the resonant Rabi frequency of the laser used to implement the gate. We outline an experiment to demonstrate the creation and detection of maximally entangled states in the system.

description: New five-dimensional charged AdS black hole solutions are found in Einstein-Gauss-Bonnet gravity and the nonlinear electrodynamics. These solutions include regular black holes as well as extremal black holes. The first law of the black hole thermodynamics is confirmed in the extended phase space where the cosmological constant is treated as the pressure. The first and second order phase transitions are investigated by observing the behavior of the heat capacity at constant pressure and the Gibbs free energy. In addition, the equation of state for the black holes and their $P-V$ criticality are studied. Finally, the critical exponents are found to be the same as those of the Van der Waals fluid.

description: One of the most frequently used arguments to explain the increased use of contractual arrangements is that risk drives the choice of contracts. However, there is limited empirical support for this argument. A Bayesian ordered probit formulation is utilized in this study to examine the impact of fresh vegetable producers’ personal characteristics on the probability of adopting marketing contracts. Among the characteristics examined are: risk aversion levels, risk perception, age, education, income, location. The findings indicate that age, farm size and the potential to expand the operation are parameters that affect the choice of contracts. On the other hand, the results do not support the risk shifting hypothesis.

description: Aggregate African agricultural production is expected to fall due to changes in temperature and rainfall under current economic models, but 65 percent of the African labor force is employed in agriculture activity. Therefore, climatic changes have the potential to significantly impact all African citizens, especially farmers. Agricultural producers must adapt to these climatic changes and the risk filled environment that rural households operate, especially small-holder farmers, which makes them particularly vulnerable to poverty and food insecurity without successful adaptation. The limited success of improving agricultural technology in Zambia makes it important to understand the determinants of changes in farm yield for major staple crops, including maize, groundnuts, sweet potatoes, and cassava. This paper generates an empirical model of the determinants of changes in farm yields using a three wave panel dataset for three agricultural seasons. Results indicate that over households have made minimal changes in crop choice and little impact has been observed due to changes in climate for Zambian farmers. Increases in yearly average rainfall and temperature positively affect maize yields. As temperatures continue to rise in the future, this relationship may not hold as the climate becomes unsuitable for large scale maize production. Changes in rainfall negatively affect household groundnut and sweet potato production which might result from switching between crops as weather changes. Finally, increased temperatures negatively affect cassava production.

 Remarks
Seegers (1996) gives a lively description of ecology and biology of specimens caught on or near Lake Rukwa.
 For distinguishing between specimens of C. discorhynchus and C. cubangoensis, the most useful anatomical characters are: longer LD, longer LA, higher number of nD and nA, higher CPD/CPL in C. discorhynchus than C. cubangoensis.

description: We present a theoretical and experimental study of Josephson vortex (fluxon) moving in the presence of spatially homogeneous dc and ac bias currents. By mapping this problem to the problem of calculating the current-voltage characteristic of a small Josephson junction, we derive the dependence of the average fluxon velocity on the dc bias current. In particular we find that the low frequency ac bias current results in an additional nonlinear damping of fluxon motion. Such ac induced damping crucially depends on the intrinsic damping parameter and increases drastically as this parameter is reduced. We find a good agreement of the analysis with both the direct numerical simulations and the experimentally measured current-voltage characteristics of a long annular Josephson junction with one trapped fluxon.

description: This paper examines the impact of technical efficiency on the optimal exit timing of farms in a stochastic dynamic framework. Starting from a standard real options approach, we incorporate technical efficiency via a production function and derive an optimal price trigger at which farms irreversibly exit production. Assuming separability of efficiency on the primal technology, we show that higher efficiency and higher returns to scale make the farm more reluctant to irreversibly exit production. We extend this model to a non-separable case, test it with West German farm-level data (2000 to 2008), and find evidence that efficiency is non–separable. We find that higher volatility of milk prices and higher efficiency delay farms' exit from the market. Volatility, however, interacts with time-varying efficiency: the propensity of inefficient farms to exit the milk market attenuates under more volatile market conditions.

description: A series of injectable in situ cross-linking hyaluronic acid/carboxymethyl cellulose based hydrogels (HA/CMC) was prepared via disulfide bonds by the oxidation of dissolved oxygen. The results showed that HA/CMC hydrogels exhibited tunable gelling time, appropriate rheology properties, high swelling ratio, good stability, and sustained drug release ability. The gelling time of HA/CMC hydrogels ranged from 1.4 to 7.0 min, and the values of the storage modulus, complex shear modulus, dynamic viscosity, and yield stress of HA3/CMC3 hydrogel were about 5869 Pa, 5870 Pa, 587 Pa·s, and 1969 Pa, respectively. The degradation percentage of HA1/CMC1, HA2/CMC2, and HA3/CMC3 hydrogels were about 60, 49, and 41% after incubating 42 days, and the in vitro cumulative release percentage of BSA from HA1/CMC1, HA2/CMC2, and HA3/CMC3 drug-loaded hydrogels were about 99, 91, and 82% after 30 days. The series of injectable in situ cross-linking HA/CMC hydrogels exhibited good comprehensive performance, signifying that these hydrogels could be potentially used in the fields of short- and medium-term controlled drug release, cell encapsulation, regenerative medicine, and tissue engineering.
Supersymmetric Continuous Spin Gauge Theory

description: Taking into account the Schuster-Toro action and its fermionic analogue discovered by us, we supersymmetrize unconstrained formulation of the continuous spin gauge field theory. Afterwards, building on the Metsaev actions, we supersymmetrize constrained formulation of the theory. In each formulation, we provide supersymmetry transformations for the $\mathcal{N}=1$ supermultiplet in four-dimensional flat space-time, in which continuous spin particle (CSP) is considered to be a complex scalar continuous spin field, and its superpartner which can be called ``\,CSPino\,'' is considered to be a Dirac continuous spin field. It is shown that the algebra of these supersymmetry transformations are closed on-shell. Furthermore, we investigate whether obtained supersymmetry transformations reproduce the known result of the higher spin gauge field theory in the helicity limit. Finally, we illustrate how these two separate set of obtained transformations are related to each other.

description: This paper examines and quantifies the consequences of increases in supplies of oil and gas from shale resources for the US economy and its agricultural and biofuel industries using a computable general equilibrium modeling framework under alternative economic conditions and emissions reduction policies. It shows that increases in supplies of oil and gas from shale resources generate enormous gains for the US economy. The question is do we use it all for higher economic growth or do we allocate part of it for reducing future global warming. This paper shows that we can sacrifice about 43% of the gains to reduce GHG emissions by 27%. Finally, the results of this paper indicate that in the presence of shale resources elimination of biofuel mandates negatively affect biofuels and crop industries. However, the impact is not huge because using shale resources increases national income and that generates a higher demand for food (including livestock product) which eventually prevents a big fall in demand for crops.

description: Economists have long held that broad-based agricultural growth is the most powerful source of poverty reduction in developing countries where most of the rural population is engaged in agriculture (Johnston and Mellor 1961; Mellor 1974; Lipton 2006). However, in Zambia’s case, despite sustained and fairly robust agricultural growth since 2000, rural poverty levels have remained at about 80% over the past 15 years. This indicates that productivity in the agricultural sector needs to be increased, especially considering that no country, apart from the island economies of Singapore and Hong Kong, has been able to sustain rapid transition out of poverty without raising the productivity in its agricultural sector.

description: Conservation farming (CF) practices are widely considered to be important components of sustainable agricultural development in Sub-Saharan Africa because of their potential to raise farm productivity and incomes while maintaining or improving soil quality and reducing vulnerability to variable climatic conditions. CF in Zambia can be traced to the 1980s when government, private sector, and donor communities started promoting CF as an alternative set of agronomic practices for Zambian smallholders (Haggblade and Tembo 2003).

description: Despite Zambia’s sustained and fairly robust agricultural growth since 2000, rural poverty levels have remained at about 80% over the past 15 years. Because over 70% of Zambia’s agricultural households are small-scale farmers cultivating less than two hectares of land, they must effectively contribute to agricultural growth if the process of growth is to be broadly based in Zambia.
4-Bit High-Speed Binary Ling Adder

Publisher: name: arXiv
Year: 2019
Subjects: subject: Hardware Architecture (cs.AR)

description: Binary addition is one of the most primitive and most commonly used applications in computer arithmetic. A large variety of algorithms and implementations have been proposed for binary addition. Huey Ling proposed a simpler form of CLA equations which rely on adjacent pair bits. Along with bit generate and bit propagate, we introduce another prefix bit, the half sum bit. Ling adder increases the speed of n-bit binary addition, which is an upgrade from the existing Carry-Look-Ahead adder. Several variants of the carry look-ahead equations, like Ling carries, have been presented that simplify carry computation and can lead to faster structures. Ling adders, make use of Ling carry and propagate bits, in order to calculate the sum bit. As a result, dependency on the previous bit addition is reduced; that is, ripple effect is lowered. This paper provides a comparative study on the implementation of the above mentioned high-speed adders.

description: From 2010 through 2012 harvest seasons, Zambian farmers produced three consecutive maize bumper harvests. The total maize production during this period was 8.6 million metric tonness, of which 4.6 million metric tonnes was a marketable surplus (CSO/MAL various years). This far exceeded the national maize consumption requirement. In an effort to prevent producer price collapse in the wake of these historic harvests, the Government’s Food Reserve Agency (FRA) was mandated to purchase approximately 80% or 3.7 million metric tonnes of the available surplus.

description: Quantized orbital structures are typical for many aspects of classical gravity (Newton's as well as Einstein's). The astronomical phenomenon of orbital resonances is a well-known example. Recently, Rothman, Ellis and Murugan (2001) discussed quantized orbital structures in the novel context of a holonomy invariance of parallel transport in Schwarzschild geometry. We present here yet another example of quantization of orbits, reflecting both orbital resonances and holonomy invariance. This strong-gravity effect may already have been directly observed as the puzzling kilohertz quasi-periodic oscillations (QPOs) in the X-ray emission from a few accreting galactic black holes and several neutron stars.

description: Even under optimistic assumptions about the rate of urbanization and growth of non-farm employment, agriculture will still be the main source of livelihood for the majority of Africans for at least the next several decades (Losch 2012). Non-farm wage jobs in Sub-Saharan Africa will be able to absorb between 40 to 65 percent of the additional 122 million workers estimated to enter the labor force before 2020 (Fine et al. 2012). This means that farming will be called upon to provide gainful employment for at least a third of young Africans entering the labor force till at least 2025.
