description: Results for response functions for kaon electroproduction on the proton are presented. A tree-level hadrodynamical model is adopted and it is shown that some of the electroproduction response functions are particularly powerful with the eye on gaining control over the parameterization of the background diagrams. The existing data set for the p(e,e'K+)Lambda reaction appears to rule out the use of a g_{K+ Lambda p} coupling constant beyond the boundaries of softly broken SU(3) flavor symmetry. Also the use of soft hadronic form factors, which has been proposed as a valid alternative for a hadrodynamical description of the p(gamma,K+)Lambda data in the resonance region, seems to be disfavored by the magnitude of the measured p(e,e'K+)Lambda cross sections.

description: We report the effect of Nb doping on the upper critical field of the cubic Laves-phase superconductor HfV$_{2}$ studied in a series of HfV$_{2-x}$Nb$_{x}$ samples with 0 $\leq$ $x$ $\leq$ 0.3 under pulsed fields up to 30 T. The undoped HfV$_{2}$ undergoes a martensitic structural transition around 110 K, and becomes superconducting below $T_{\rm c}$ = 9.4 K. Upon Nb doping, while the structural transition is suppressed for $x$ $\geq$ 0.1, a maximum in $T_{\rm c}$ of 10.1 K and zero-temperature upper critical field $B_{\rm c2}$(0) of 22.4 T is found at $x$ = 0.2, which is ascribed to an increase of the density of states at the Fermi level. For all samples, the temperature dependence of $B_{\rm c2}$ can be well described by the Werthamer-Helfand-Hohenberg (WHH) theory that takes into account both the spin paramagnetic effect and spin orbit scattering. In addition, a comparison is made between the $B_{\rm c2}$ behavior of HfV$_{2-x}$Nb$_{x}$ and those of Nb-Ti and Nb$_{3}$Sn.

description: The quasiexcitations of quantum Hall systems at the filling factor $ν= p/(2pq \pm 1)$ are studied in terms of chargeon and fluxon introduced previously as constituents of an electron at $ν= 1/2$. At temperatures $T < T_{\rm PFS}(ν)$, the phenomenon so-called particle-flux separation takes place, and chargeons and fluxons are deconfined to behave as quasiparticles. Bose condensation of fluxons justify the (partial) cancellation of external magnetic field. Fluxons describe correlation holes, while chargeons describe composite fermions. They contribute to the resistivity $ρ_{xy} = h/(νe^2)$ additively.

description: We examine the stability of ${\rm AdS}_p \times {\rm S}^n \times {\rm S}^{q-n}$. The initial data constructed by De Wolfe et al \cite{Gary} has been carefully analyised and we have confirmed that there is no lower bound for the total mass for $q< 9$. The effective action on ${\rm AdS}_p$ has been derived for dilatonic compactification of the system to describe the non-linear fluctuation of the background space-time. The stability is discussed applying the positive energy theorem to the effective theory on AdS, which again shows the stability for $q \geq 9$.

description: We use Very Long Baseline Interferometry to measure the proper motions of three black hole X-ray binaries (BHXBs). Using these results together with data from the literature and Gaia-DR2 to collate the best available constraints on proper motion, parallax, distance and systemic radial velocity of 16 BHXBs, we determined their three dimensional Galactocentric orbits. We extended this analysis to estimate the probability distribution for the potential kick velocity (PKV) a BHXB system could have received on formation. Constraining the kicks imparted to BHXBs provides insight into the birth mechanism of black holes (BHs). Kicks also have a significant effect on BH-BH merger rates, merger sites, and binary evolution, and can be responsible for spin-orbit misalignment in BH binary systems. $75\%$ of our systems have potential kicks $>70\,\rm{km~s^{-1}}$. This suggests that strong kicks and hence spin-orbit misalignment might be common among BHXBs, in agreement with the observed quasi-periodic X-ray variability in their power density spectra. We used a Bayesian hierarchical methodology to analyse the PKV distribution of the BHXB population, and suggest that a unimodal Gaussian model with a mean of $107\pm16\,\rm{km~s^{-1}}$ is a statistically favourable fit. Such relatively high PKVs would also reduce the number of BHs likely to be retained in globular clusters. We found no significant correlation between the BH mass and PKV, suggesting a lack of correlation between BH mass and the BH birth mechanism. Our Python code allows the estimation of the PKV for any system with sufficient observational constraints.

description: Food additive is a double-edged sword. It has merits and demerits. Food additives have such merits as improving sensory properties of foods, preventing deterioration and extending the shelf life, increasing varieties of foods, enhancing convenience of foods, facilitating food processing, and satisfying other demands. However, excessive and illegal use of food additives will exert adverse influence on food security. Therefore, it is required to take proper measures to bring merits of food additives into full play, and get rid of their demerits.

Exact and efficient calculation of derivatives of Lagrange multipliers for molecular dynamic simulations of biological molecules

description: In the simulation of biological molecules, it is customary to impose constraints on the fastest degrees of freedom to increase the time step. The evaluation of the involved constraint forces must be performed in an efficient manner, for otherwise it would be a bottleneck in the calculations; for this reason, linearly-scaling calculation methods have become widely used. If integrators of order higher than 2 (e.g. Gear predictor-corrector methods) are used to find the trajectories of atoms, the derivatives of the forces on atoms with respect to the time also need to be calculated, which includes the derivatives of constraint forces. In this letter we prove that such calculation can be analytically performed with linearly scaling numerical complexity (O(Nc), being Nc the number of constraints). This ensures the feasibility of constrained molecular dynamics calculations with high-order integrators.

description: In order to establish a supply system for energy resource coupled with the environment, the production technology of sugar beets was explored as a biological energy source. The low-humic andosol as the experimental soil, the panting method was direct planting, and cultivation technique was minimum tillage direct planting method. The control was conventional tillage transplant and no tillage direct planting. The results demonstrated that data revealed that the energy cost of no tillage and a direct planting method was 105 GJ/hm2 on average for two years, while that of the conventional tillage method was 112 GJ/hm2 per year. The ratio of output to input showed that the direct planting with no tillage was more efficient (3.61) than the conventional tillage (3.01). Moreover, the emission of CO2 into the atmosphere with no tillage and the direct planting was 71% of the conventional tillage planting technique. Therefore, direct planting without tillage reduces the impact on the environment.

description: According to spatial distribution of climate disasters in Nanning City and physiological and ecological indicator demands of sugarcane, with the aid of HJ-1 CCD satellite remote sensing images, basic meteorological data and geographic information data, this paper established the model for predicting climatic yield of sugarcane in Nanning City, to predict total yield of sugarcane in Nanning City. Results indicated that the distribution of sugarcane in Nanning City is greatly influenced by drought. In 2010, regions suffered from drought had sugarcane planting area of 346.20 km2, accounting for 18.88% of the total sugarcane planting area. The influence of frost disaster on distribution of sugarcane in Nanning City is limited. Regions suffered from frost had sugarcane planting area of only 67.1 km2, taking up 3.75% of the total sugarcane planting area. In 2010, the climatic yield of sugarcane in Nanning City was 8.8446 million tons. It proved that the prediction accuracy of the model is up to 90%.

description: The gravitational redshift formula is usually derived in the geometric optics approximation. In this note we consider an exact formulation of the problem in the Schwarzschild space-time, with the intention to clarify under what conditions this redshift law is valid. It is shown that in the case of shocks the radial component of the Poynting vector can scale according to the redshift formula, under a suitable condition. If that condition is not satisfied, then the effect of the backscattering can lead to significant modifications. The obtained results imply that the energy flux of the short wavelength radiation obeys the standard gravitational redshift formula while the energy flux of long waves can scale differently, with redshifts being dependent on the frequency.

description: The chain rule for the classical relative entropy ensures that the relative entropy between probability distributions on multipartite systems can be decomposed into a sum of relative entropies of suitably chosen conditional distributions on the individual systems. Here, we prove a similar chain rule inequality for the quantum relative entropy in terms of channel relative entropies. The new chain rule allows us to solve an open problem in the context of asymptotic quantum channel discrimination: surprisingly, adaptive protocols cannot improve the error rate for asymmetric channel discrimination compared to non-adaptive strategies. In addition, we give examples of quantum channels showing that the channel relative entropy is not additive under the tensor product.

description: In summer maize growth period, the water supply and demand ratio is regarded as the evaluation index of drought and waterlogging for the summer maize in Liaocheng City. Using GIS, statistics, agrometeorology and other methods, we analyze the precipitation during the summer maize growth period in Luxi Plains from 1961 to 2011. Through the calculation of drought and waterlogging index, it indicates that the disasters of drought and waterlogging frequently occur during the summer maize growth period, mainly affected by the drought; the frequency of occurrence of drought accounts for 80.4%, that is, it is very prone to serious drought phenomenon, seriously affecting the normal growth and development of summer maize during the seedling period. With global warming, the industrial and domestic water demand is increasing year by year, so it is extremely difficult to increase the water diversion to solve the problem of water shortage for the growth of summer maize. Finally we put forth the following recommendations: (i) Selecting drought-resistant varieties, and improving the water resource use efficiency; (ii) Promoting the water and fertilizer coupling, sprinkler irrigation, drip irrigation, micro-irrigation and other water-saving irrigation technologies, and improving the water use efficiency; (iii) Promoting the ditch, ridge and laminating cultivation technology, reducing the field evapotranspiration, keeping warming and conserving moisture, and saving water resources; (iv) Strengthening the construction of water conservancy facilities, so that it can be irrigated during drought and drained during waterlogging; (v) During dry season, timely organizing artificial rainfall operation, and increasing precipitation in arid areas to ease drought; (vi) Rationally exploiting the groundwater, and improving the underground water use efficiency.

description: Power spectra always play an important role in the theory of inflation. In particular, the ability to reproduce the galaxy matter power spectrum and the CMB temperature angular power spectrum coefficients to high accuracy is often considered a triumph of inflation. In our previous work, we presented an alternative explanation for the matter power spectrum based on nonperturbative quantum field-theoretical methods applied to Einstein's gravity, instead of inflation models based on scalar fields. In this work, we review the basic concepts and provide further in-depth investigations. We first update the analysis with more recent data sets and error analysis, and then extend our predictions to the CMB angular spectrum coefficients, which we did not consider previously. Then we investigate further the potential freedoms and uncertainties associated with the fundamental parameters that are part of this picture, and show how recent cosmological data provides significant constraints on these quantities. Overall, we find good general consistency between theory and data, even potentially favoring the gravitationally-motivated picture at the largest scales. We summarize our results by outlining how this picture can be tested in the near future with increasingly accurate astrophysical measurements.

description: Past decades have witnessed the unprecedented success in very-large scale integration-based electronic computing, as indicated by the Moore’s law. Transistors continue to scale down from micrometer to nanometer and computing cores continue to increase with all the benefits of lower power consumption and higher speed coming naturally until the falter of Moore’s law in recent years as nanofabrication technology approaches its inevitable limit. Remarkable efforts have been made to develop high-speed and power-efficient computing alternatives in this post-Moore’s law era. The exploration of optical computing started as early as ~1970s when integrated electronic computing was just about to take off. The continuous success of electronic computing over decades has not slowed down but instead stimulated the research on optical computing. It is because photonics own unique and fascinating properties such as ultrahigh speed, high bandwidth, and various multiplexing techniques, making it a promising candidate to supersede electronics especially when electronics face unsolvable obstacles. Fortunately, in this post-Moore’s law era, integrated photonics has evolved rapidly with abundant passive and active micrometer-size components available with ultralow power consumption. It enables integrated optical computing to be comparable with transistor-based electronic computing in terms of speed and power. In this dissertation, a new architecture of electronic-photonic computing will be presented, which makes the full use of electronics and photonics to achieve ultrahigh-speed and low-power-consumption computing that are comparable with the state-of-the-art transistors-based electronic computing. This dissertation will cover bottom-to-top discussions, ranging from gates, circuits, to automatic design algorithm, to architecture and entire system. First, it starts with the introduction of electro-optic logic and then the design and analysis of fundamental logic gates and circuits along with the essential components such as electro-optic modulators. Second, an automated logic synthesis algorithm called And-Inverter Graph will be presented, which is capable of designing computing circuits using these fundamental logic gates automatically and efficiently. Third, an electronic-photonic arithmetic logic unit is proposed with an experimental demonstration of 4-bit circuit operating at 20 GHz. Thorough discussion of the performance is also conducted which shows its potential to surpass the state-of-the-art transistors-based computing circuits in terms of speed and power. Forth, a Moore’s law in optical computing is discussed with one promising method called multi-operand logic gates provided. Lastly, architectural considerations of electronic-photonic computing are presented.

description: Realising just and equitable pathways to urbanisation is a major challenge in urban research and practice. Environmental justice literature outlines approaches for just distribution and meaningful public participation by including and recognising different groups of residents. Despite institutionalised support for just procedures in urban planning, citizens do not necessarily perceive outcomes as just and inclusive. This paper aims to understand and critically examine procedural justice in the urban development process in a marginalised neighbourhood in Malmö, Sweden. We use the theories of procedural justice and communicative planning to provide a layered assessment of procedural justice. The overall findings show critical discrepancies between institutionalised and perceived justice. The legal guidelines are vague and lack consistency in implementation from the city’s point of view. This in turn weakens citizen influence in public participation. Additionally, this case reveals novel tensions in operationalising procedural justice during the COVID-19 pandemic. The paper concludes that even if there is a mandatory requirement for participation with affected groups of citizens, planners must represent various interests, and procedural justice is not being operationalised. Just development and transformation of the urban environment requires further unpacking of the interaction between the official, the applied, and the lived dimensions of procedural justice.

description: Low-lying collective vibrational excitations of ⁹²Zr have been investigated with electron scattering at the S-DALINAC. The form factors of isospin polarized one-quadrupole phonon states of ⁹²Zr at the Z = 40 proton subshell closure have been measured and the momentum-transfer dependence of the form factors for the one-quadrupole phonon states have been compared to the prediction of the Quasiparticle Phonon Model. The E2 transition strengths of the one-quadrupole phonon states and the E3 transition strength of the one-octupole phonon state have been extracted. A comparison to the data on ⁹⁴Mo and previous spectroscopic information on mixed-symmetric states (MSSs) of ⁹²Zr will be given.

description: Soil C/N ratio is an important influencing factor in soil nitrogen cycling. Two-year old apple trees (Borkh. cv. ‘Fuji’/ Malus hupehensis) were used to understand the effect of soil C/N ratio [6.52 (CK), 10, 15, 20, 25, 30, 35 and 40] on apple growth and nitrogen utilization and loss by using 15N trace technique. The results showed that, with the increasing of soil C/N ratio, apple shoot length and fresh weight increased at first, and then decreased; the higher apple shoot length and fresh weight appeared in C/N=15, 20 and 25 treatments, and there were no significant differences among these three treatments, but significantly higher than the other treatments. Statistical analysis revealed that there was significant difference in nitrogen utilization rate between the different treatments, the highest N utilization rate was occurred in soil C/N=25 treatment which value was 22.87%, and there was no significant difference between soil C/N=25 and C/N=20 treatments, but both the two treatments were significantly higher than the other treatments; Soil C/N=40 had the lowest N utilization rate which value was 15.43%, and this value was less than CK (16.65%). The proportion of plant absorption nitrogen from fertilizer was much higher when the value of soil C/N ratio in the range of 15-25, but the percentage of plant absorption nitrogen from soil was much higher when the soil C/N ratio was too low (<15) or high (<25). Amount of residual nitrogen in soil increased gradually with the soil C/N ratio increasing, the amount of residual nitrogen in C/N=40 treatment was 1.32 times than that in CK. With the increasing of soil C/N ratio, fertilizer nitrogen loss decreased at first, and then increased, fertilizer nitrogen loss was the minimum in C/N=25 treatments (49.87%) and the maximum were occurred in CK (61.54%). Therefore, regarding the apple growth and nitrogen balance situation, the value of soil C/N ratio in the range of 15-25 would be favorable for apple growth and could increase effectively nitrogen fixed by soil, reduce nitrogen loss, and improve the nitrogen utilization ratio.

description: By introducing development situation of specialized cooperatives and vegetable specialized cooperatives in China, this paper discussed existing problems in the process of development of China’s vegetable specialized cooperatives. Then, it made efficiency evaluation on typical vegetable specialized cooperatives in 3 districts of Chongqing Municipality by the DEA method. Considering traditional DEA model has drawbacks, it introduced super efficiency DEA model to make complete identification and ordering of cooperatives. On this basis, it divided efficiency value into pure technical efficiency and scale efficiency, and classified cooperatives into 4 categories according to efficiency characteristics of non-complete effective cooperatives. Finally, it came up with recommendations and countermeasures for improving efficiency of specialized cooperatives from raising technical level and increasing members of specialized cooperatives.

description: Successful replacement of B by C in the series MgB2-xCx for values of x upto 0.3 are reported. Resistivity and ac susceptibility measurements have been carried out in the samples. Solubility of carbon, inferred from the observed change in the lattice parameter with carbon content indicates that carbon substitutes upto x=0.30 into the MgB2 lattice. The superconducting transition temperature, TC measured both by zero resistivity and the onset of the diamagnetic signal shows a systematic decrease with increase in carbon content upto x=0.30, beyond which the volume fraction decreases drastically. The temperature dependence of resistivity in the normal state fits to the Bloch-Gruneisen formula for all the carbon compositions studied. The Debye temperatures, extracted from the fit is seen to decrease with carbon content from 900K to 525K, whereas the electron-phonon interaction parameter, obtained from the McMillan equation using the measured TC and the Debye temperature, is seen to increase monotonically from 0.8 in MgB2 to 0.9 in the x=0.50 sample. The ratio of the resistivities between 300K and 40K versus TC is seen to follow the Testardi correlation for the C substituted samples. The decrease in TC is argued to mainly arise due to large decrease in the Debye temperature with C concentration and a decrease in the hole density of states at N(EF).

description: The gravitational equations of the three dimensional (3D) brane world are investigated for both off-diagonal and warped 5D metrics which can be diagonalized with respect to some anholonomic frames when the gravitational and matter fields dynamics are described by mixed sets of holonomic and anholonomic variables. We construct two new classes of exact solutions of Kaluza-Klein gravity which generalize the Randall-Sundrum metrics to configurations with running on the 5th coordinate gravitational constant and anisotropic dependencies of effective 4D constants on time and/or space variables. We conclude that by introducing gauge fields as off-diagonal components of 5D metrics, or by considering anholonomic frames modelling some anisotropies in extra dimension spacetime, we induce anisotropic tensions (gravitational polarizations) and running of constants on the branes. This way we can generate the TeV scale as a hierarchically suppressed anisotropic mass scale and the Newtonian and general relativistic gravity are reproduced with adequate precisions but with corrections which depend anisotropically on some coordinates.

description: The ability to navigate in complex, inhomogeneous environments is fundamental to survival at all length scales, giving rise to the rapid development of various subfields in bio-locomotion such as the well established concept of chemotaxis. In this work, we extend this existing notion of taxis to rotating environments and introduce the idea of roto-taxis to bio-locomotion. In particular, we explore both overdamped and inertial dynamics of a model synthetic self-propelled particle in the presence of constant global rotation, focusing on the particle's ability to localize near a rotation center as a survival strategy. We find that in the overdamped regime, the swimmer is in general able to generate a self restoring active torque that enables it to remain on stable epicyclical-like trajectories. On the other hand, for underdamped motion with inertial effects, the intricate competition between self-propulsion and inertial forces, in conjunction with the rototactic torque leads to complex dynamical behavior with non-trivial phase space of initial conditions which we reveal by numerical simulations. Our results are relevant for a wide range of setups, from vibrated granular matter on turntables to microorganisms or animals swimming near swirls or vortices.

The Effect of Shear Viscosity on Spectra, Elliptic Flow, and HBT Radii
Creators: name: Teaney, D.
Publisher: name: arXiv
Year: 2003
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: I calculate the first correction to the thermal distribution function of an expanding gas due to shear viscosity. With this modified distribution function I estimate viscous corrections to spectra, elliptic flow, and HBT radii in hydrodynamic simulations of heavy ion collisions using the blast wave model. For reasonable values of the shear viscosity, viscous corrections become of order one when the transverse momentum of the particle is larger than 1.7 GeV. This places a bound on the $p_{T}$ range accessible to hydrodynamics for this observable. Shear corrections to elliptic flow cause $v_{2}(p_{T})$ to veer below the ideal results for $p_{T} \approx 0.9$ GeV. Shear corrections to the longitudinal HBT radius $R^{2}_{L}$ are large and negative. The reduction of $R_{L}^2$ can be traced to the reduction of the longitudinal pressure. Viscous corrections cause the longitudinal radius to deviate from the $\frac{1}{\sqrt{m_T}}$ scaling which is observed in the data and which is predicted by ideal hydrodynamics. The correction to the sideward radius $R^{2}_{S}$ is small. The correction to the outward radius $R^{2}_{O}$ is also negative and tends to make $R_{O}/R_{S} \approx 1$.
