description: We have looked into an experiment that has been termed the ``canonical example'' of jamming: granular material, clogging the outlet of a container as it is discharged by gravity. We present quantitative data of such an experiment. The experimental control parameter is the ratio between the radius of the orifice and the radius of the beads. As this parameter is increased, the jamming probability decreases. However, in the range of parameters explored, no evidence of criticality --in the sense of a jamming probability that becomes infinitely small for a finite radius-- has been found. We draw instead a comparison with a simple model that captures the main features of the phenomenon, namely, percolation in one dimension. The model gives indeed a phase transition, albeit a special one.

description: Gigahertz-Peaked spectrum (GPS) sources are compact active galactic nuclei, presumably young precursors of bright radio sources. The study of GPS radio properties provides information about the features of synchrotron radiation in extragalactic sources. Also in applied research GPS sources are useful as compact stationary radio sources in the sky for astrometric purposes. This paper presents the results of a multifrequency GPS study based on quasi-simultaneous measurements with the RATAN-600 radio telescope during the 2006-2017. The catalog containing spectral flux densities measured at six frequencies (1.1, 2.3, 4.8, 7.7/8.2, 11.2, and 21.7 GHz) have been obtained. In addition, for the analysis of radio spectra, data from the following low-frequency surveys have been used: GLEAM (GaLactic and Extragalactic All-sky Murchison widefield array survey) and TGSS (Tata institute for fundamental research GMRT Sky Survey) and high-frequency measurements from Planck survey. A total number of 164 GPS and candidates to GPS have been identified (17 of them are new discoveries), which makes up a small fraction of GPS in the initial sample of bright AGNs, about 2%. The physical properties and formation conditions of synchrotron radiation is found to be quite different in GPS of different AGN types. The deficit of distant GPS ($z > 2$) with low maximum frequencies (less than 1 GHz) is confirmed. The existing 'size - peak frequency' anticorrelation is continuous. The continuum radio spectra are found to become statistically steeper with increasing redshift.

description: Modelling long-time convective flows in the interiors of stars is extremely challenging using conventional compressible hydrodynamics codes due to the acoustic timestep limitation. Many of these flows are in the low Mach number regime, which allows us to exploit the relationship between acoustic and advective time scales to develop a more computationally efficient approach. MAESTROeX is an open source low Mach number stellar hydrodynamics code that allows much larger timesteps to be taken, therefore enabling systems to be modelled for much longer periods of time. This is particularly important for the problem of convection in the cores of rotating massive stars prior to core collapse. To fully capture the dynamics, it is necessary to model these systems in three dimensions at high resolution over many rotational periods. We present an overview of MAESTROeX's current capabilities, describe ongoing work to incorporate the effects of rotation and discuss how we are optimising the code to run on GPUs.

description: The MNS matrix structure emerging as a result of recent neutrino measurements strongly suggests two large mixing angles (solar and atmospheric) and one small angle (|U_e3| << 1). Especially when combined with the neutrino mass hierarchy, these values turn out to impose rather stringent constraints on possible flavor models connecting the three active fermion generations. Specifically, we show that an extremely small value of |U_e3| would require fine tuning of Majorana mass matrix parameters, particularly in the context of seesaw models.

MATERIAL EXAMINED. — Station 2: slide 11.019.03a, 1 fragment (10 segments) of an immature specimen; IRScNB, I.G. 32392.
REMARKS
Dorsal bundles with 4-5 bifid setae per bundle, with upper tooth slightly shorter than lower, and 3-4 smooth and short hair setae. Up to seven setae in ventral bundles, with upper tooth slightly shorter than lower. No coelomocytes.
This specimen is tentatively attributed to the genus Aulodrilus Bretscher, 1899 on the basis of its setal features. It is also conceivable that it might belong to Branchiura sowerbyi Beddard, 1892, although in the latter species upper teeth in crochets are either absent or much shorter than those observed on the present specimen.

description: The presence of multiple populations (MPs) in almost all globular clusters (GCs) older than ~10 Gyr, has caught lots of attention. Recently, cumulative evidence indicates that extragalactic GCs that are older than 2 Gyr, seem to also harbor MPs, however, those that are younger than 2 Gyr do not. These observations seem to imply that age is a primary property that controls the presence of MPs in star clusters. However, because of the lack of studies of {intermediate-age (~2--6 Gyr-old),} low mass clusters, it is unclear if the cluster mass, in addition to age, also plays a role in the occurrence of MPs. In this work, we studied a $\sim$4 Gyr-old, low mass (~23,000 Msun) cluster, Lindsay-113, in the Small Magellanic Cloud. Using Hubble Space Telescope photometry, we find that the width of the red-giant branch in this cluster, when measured in a specific color index that is sensitive to star-to-star chemical variations, {can be adequately explained by a "simple" stellar population model with some possible noises contributed from measurement uncertainty, photometric artifact, as well as differential reddening. The comparison of observations with predictions from synthetic spectra indicates that the internal chemical spread in nitrogen abundance, which is a signature of MPs, would not exceed 0.2 dex. Since Lindsay 113 is significantly older than other GCs with MPs, we suggest that the onset of MPs is likely determined by the combination of cluster age and mass.

description: Background: Elevated liver enzymes and chronic liver disease are associated with increased morbidity and mortality. Broad availability of internet questionnaires obtains representative insights into awareness of (chronic) liver disease in the general population. Also, these tools may be used to identify persons and populations at risk to prevent advanced liver disease. Methods: An online questionnaire regarding awareness of liver disease, risk behavior and awareness of own liver tests was implemented online. During 43 months study period, 210,230 participants accessed the online questionnaire. Of these, 117,446 individuals completed the survey. All database access and input were registered and collected in a SQL based database for further evaluation. Results: Awareness of own liver status was lower than expected. About 50.7% of all participants were uncertain about their liver enzyme status. In turn, risk behavior continues to be considerably high as 38.8% of participants stated high-risk behavior for alcohol consumption and 2.2% high-risk substance abuse such as cocaine or heroin. Our questionnaire was predominantly answered by participants under 65 years of age. Participants with high BMI may have been underrepresented. Conclusion: Our study demonstrated the urgent need for improved liver screening, health education regarding risk behavior and improved awareness campaigns on liver disease. Interest of the general population may be presumed as more than 200,000 people accessed our test of their own accord.

description: We study the large-time behaviour of Brownian particles moving through a viscous medium in a confined potential, and which are further subjected to position-dependent driving forces that are periodic in time. We focus on the case where these driving forces are rapidly oscillating with an amplitude that is not necessarily small. We develop a perturbative method for the high-frequency regime to find the large-time behavior of periodically driven stochastic systems. The asymptotic distribution of Brownian particles is then determined to second order. To first order, these particles are found to execute small-amplitude oscillations around an effective static potential which can have interesting forms.

description: If the dark sector of the Universe consists of ultra-light scalars, their coupling to photon via a Chern-Simons term would induce a rotation of the polarization plane of the cosmic microwave background (CMB). This rotation would convert E -mode polarization into B -mode polarization, resulting in new CMB BB correlation and parity-violating TB and EB cross correlations. We review the subject giving details about the derivation of the rotational effects and summarizing the possible signals in current and future CMB B-mode experiments.

description: This report evaluates the United States and world corn and soybean markets for the 2013-2022 period using the Global Corn and Soybean Policy Simulation Model. This analysis is based on a series of assumptions about general economic conditions, agricultural policies, weather conditions, and technological change. Corn-based ethanol production has influenced thenUnited States corn industry. As long as the production of corn-based ethanol remains strong, corn prices will likely remain at a level higher than the long term average. However, changes in the Federal fuel mandates could significantly impact the world corn market. Under the current assumptions in the model, corn price is expected to remain in a range between $4.30 and $6.50 per bushel over the 2013-2022 period. Chinese soybean import is a leading factor influencing the world soybean market. China currently imports 66% of soybean trade in the world market, and that is expected to increase to about 70% by 2022. Major exporters will continue to be the U.S., Brazil and Argentina. However both Brazil and Argentina could increase exports, while U.S. exports will remain at the current level. Soybean prices are expected to remain near $12.00/bushel over the time period.

REMARKS
This Trichodrilus material is only available as immature specimens or fragments, and cannot be identified at the species level. Most Trichodrilus species occupy ground water habitats and have localized distributions. Given the general trend in Trichodrilus for groundwater habitats, we consider these undetermined specimens as stygobionts.

description: We use an off - lattice bead - spring model of a self - avoiding polymer chain immersed in a 3-dimensional quenched random medium to study chain dynamics by means of a Monte - Carlo (MC) simulation. The chain center of mass mean-squared displacement as a function of time reveals two crossovers which depend both on chain length $N$ and on the degree of Gaussian disorder $Δ$. The first one from normal to anomalous diffusion regime is found at short time $τ_1$ and observed to vanish rapidly as $τ_1 \propto Δ^{- 11}$ with growing disorder. The second crossover back to normal diffusion, $τ_2$, scales as $τ_2 \propto N^{2ν+ 1} f(N^{2-3ν}Δ)$ with $f$ being some scaling function. The diffusion coefficient $D_N$ depends strongly on disorder and drops dramatically at a {\em critical dispersion} $Δ_{c} \propto N^{-2 + 3ν}$ of the disorder potential so that for $Δ> Δ_c$ the chain center of mass is practically frozen.The time-dependent Rouse modes correlation function $C_{p}(t)$ reveals a characteristic plateau at $Δ> Δ_c$ which is the hallmark of a non - ergodic regime. These findings agree well with our recent theoretical predictions.

Theory of Applying Heat Flow from Thermostatted Boundary Walls: Dissipative and Local-Equilibrium Responses and Fluctuation Theorems

description: We construct a microscopic theory of applying a heat flow from thermostatted boundary walls in the film geometry. We treat a classical one-component fluid, but our method is applicable to any fluids and solids. We express linear response of any variable ${\cal B}$ in terms of the time-correlation functions between $\cal B$ and the heat flows ${\cal J}_K$ from the thermostats to the particles. Furthermore, the surface variables ${\cal J}_K$ can be written in the form of space integrals of bulk quantities from the equations of motion. Owing to this surface-to-bulk relation, the steady-state response functions consist of dissipative and local-equilibrium parts, where the former gives rise to Fourier's law with Green's expression for the thermal conductivity. In the nonlinear regime, we derive the steady-state distribution in the phase space in the McLennan-Zubarev form from the first principles. Some fluctuation theorems are also presented.

description: The epizootiology of Entomophthora canarjensis Macleod, Tyrrell, & Soper in populations of the woolly pine needle aphid (Schizolachnus piniradiatae (Davidson)) was investigated during a 5-year period in an isolated plantation of red pine (Pinus resinosa Aitj in northern Ontario. Climatic factors did not limit the spread of the fungus; the major controlling factors were the density of the fungus inoculum and the density and spatial distribution of ti1tl host. An epizootic killed nearly 100 percent of the aphids in early October 1964, and in the subsequent 2 years E. canadensis began to spread at lower population densities and continued to spread faster than during 1961-64, probably because the inoculum density was greater after the epizootic.

description: The present research is realised in the frame of the ZEU project “LUCA” (Land Use, Ecosystem Services and Human Welfare in Central Asia). LUCA builds a platform for joint analysis of land use effects for a whole region, involving participants from various countries of Central Asia. In the transition from planned to market economies, the Central Asian Republics experienced rising poverty, food insecurity and malnutrition as well as serious degradation of water and land resources. The process to a market oriented economy has not been adequately supported by national institutional development. It resulted in a reduced living standard. Land use strategies in Uzbekistan determine the level of food security. While the area of rangelands is vast, the livestock farming and production of grains, fruits and vegetables play a major role in food security and also are the basic source of rural population income. More than 60% of Uzbeks live in rural area. Uzbekistan produces adequate calories to supply the population but almost 30 % lives below the food poverty line (IFPRI, 2006). The poorest population spends more than 60 % of income for food and takes a diet dominated by cereals. The existing system of the “state order” to produce cotton and wheat does not allow to growing up food crops in adequate amount. The survey is focused on questions on the socio-economic situation, societal determinants of food supply, food consumption patterns, eating habits, and coping strategies managing food crisis on household level. Markhamat region of Andijan province and Denau region of Surkhandarya province are the two most populated regions of Uzbekistan and presented as the study area. The data collection is based on the own structured questionnaire, on the Household Food Security Survey Module (HFSSM), Food Consumption Score (FCS), and Food List Recall. Data analysis was done with SPSS. The main results show the percentage of food secure and food insecure households as well as the food consumption status of these households concerning cash and food crops households are producing on their farm land and/or on their homestead plot. The results show that the main indicator of the level of income, food security situation and food consumption status of household is the production strategy. Thereby the more households produce cotton and wheat they will have less income, and a worse food security and food consumption status.

description: The main factors of dust storms rise are recurrence of strong winds and vast area of dust emission sites, where the latter is the subject of change. During the last decades owing to the crisis situation in the Aral region the total area of dust emission sites increased significantly because of the shrinking of the Aral Sea and consequent drying of its exposed bottom and deltaic areas of Amudarya and Syrdarya Rivers (Orlovsky et al 2004). The Aral Sea problem has formed by the relations between humanity and nature and human attitude without affection by seeking to development to the environment. During the one generation life the Aral Sea had already dried and there is a desert instead of it. Under conditions of the Aral Sea ecological crisis, natural ecosystems within a 400 km radius of the seashore have undergone transformations. In region of Aral Sea crisis cause many problems depends and affects each other. In my research I point out one problem in this region dust storms and dust transfer. The aim of this research approach is to analyses spatial and temporal distribution of dust deposition in the southern Aral Sea region. Dust occurrence and its effects lead to the modification of the mineral structures of the arable land. Productive soils are degraded and salinized the agricultural productivity is decreasing. study the influence of negative chemical elements in soil.

title: Sustainable intensification of arable agriculture
title: The role of Earth Observation in quantifying the agricultural landscape

Creators: name: Hunt, Merryn

description: By 2050, global food production must increase by 70% to meet the demands of a growing population with shifting food consumption patterns. Sustainable intensification has been suggested as a possible mechanism to meet this demand without significant detrimental impact to the environment. Appropriate monitoring techniques are required to ensure that attempts to sustainably intensify arable agriculture are successful. Current assessments rely on datasets with limited spatial and temporal resolution and coverage such as field data and farm surveys. Earth Observation (EO) data overcome limitations of resolution and coverage, and have the potential to make a significant contribution to sustainable intensification assessments. Despite the variety of established EO-based methods to assess multiple indicators of agricultural intensity (e.g. yield) and environmental quality (e.g. vegetation and ecosystem health), to date no one has attempted to combine these methods to provide an assessment of sustainable intensification. The aim of this thesis, therefore, is to demonstrate the feasibility of using EO to assess the sustainability of agricultural intensification. This is achieved by constructing two novel EO-based indicators of agricultural intensity and environmental quality, namely wheat yield and farmland bird richness. By combining these indicators, a novel performance feature space is created that can be used to assess the relative performance of arable areas. This thesis demonstrates that integrating EO data with in situ data allows assessments of agricultural performance to be made across broad spatial scales unobtainable with field data alone. This feature space can provide an assessment of the relative performance of individual arable areas, providing valuable information to identify best management practices in different areas and inform future management and policy decisions. The demonstration of this agricultural performance assessment method represents an important first step in the creation of an operational EO-based monitoring system to assess sustainable intensification, ensuring we are able to meet future food demands in an environmentally sustainable way.

description: The spatial pattern of glacial retreat in Central Asian highlands are more intensive in last decades and impact on water resources are noteworthy in arid regions of Kyrgyz Republic. This research is an effort to assess the recent glacial retreat in Chon and Kichi Naryn catchments. The study conducted for period of 45 years (1965-2010) using 1:25000 scale topographic maps and ALOS/AVNIR satellite imagery shows that glacier area decreased by 21.3% in total. The dramatic changes have happened in south-facing glaciers than north facing glaciers with areal loss of loss of 23.6% and 19.8% respectively. The accelerated changes in glacial retreat will have compounding effect on shortage of water in densely populated areas and also increase in frequencies glacial induced hazards.

description: The presence of cluster-like narrow resonances in the vicinity of reaction/decay thresholds is a ubiquitous phenomenon with profound consequences. We argue that the continuum coupling, present in the open quantum system description of the atomic nucleus, can profoundly impact the nature of near-threshold states. In this Letter, we discuss the structure of the recently observed near-threshold resonance in $^{11}$B, whose very existence explains the puzzling beta-delayed proton emission of the neutron-rich $^{11}$Be.

description: Organic thermoelectrics are attractive for the fabrication of flexible and cost-effective thermoelectric generators (TEGs) for waste heat recovery, in particular by exploiting large-area printing of polymer conductors. Efficient TEGs require both p- and n-type conductors: so far, the air instability of polymer n-type conductors, which typically loose orders of magnitude in electrical conductivity (σ) even for short exposure time to air, has impeded processing under ambient conditions. Here we tackle this problem in a relevant class of electron transporting, naphthalene-diimide co-polymers, by substituting the imide oxygen with sulphur. n-type doping of the thionated co-polymer gives rise to a higher σ with respect to the non-thionated one, and most importantly, owing to a reduced energy level of the lowest-unoccupied molecular orbital, σ is substantially stable over 16 h of air exposure. This result highlights the effectiveness of chemical tuning to improve air-stability of n-type solution-processable polymer conductors and shows a path towards ambient large-area manufacturing of efficient polymer TEGs.
Dynamics of Shear-Transformation Zones in Amorphous Plasticity: Energetic Constraints in a Minimal Theory

description: We use energetic considerations to deduce the form of a previously uncertain coupling term in the shear-transformation-zone (STZ) theory of plastic deformation in amorphous solids. As in the earlier versions of the STZ theory, the onset of steady deformation at a yield stress appears here as an exchange of dynamic stability between jammed and plastically deforming states. We show how an especially simple ``quasilinear'' version of this theory accounts qualitatively for many features of plasticity such as yielding, strain softening, and strain recovery. We also show that this minimal version of the theory fails to describe certain other phenomena, and argue that these limitations indicate needs for additional internal degrees of freedom beyond those included here.

description: The evolution of the two-point functions of autonomous one-dimensional single-species reaction-diffusion systems with nearest-neighbor interaction and translationally-invariant initial conditions is investigated. It is shown that the dynamical phase structure of such systems consists of five phases. As an example, a one-parameter family is introduced which can be in each of these phases.

description: Models and observations indicate that the impact of matter accreting onto the surface of young stars produces regions at the base of accretion columns, in which optically thin and thick plasma components coexist. Thus an accurate description of these impacts requires to account for the effects of absorption and emission of radiation. We study the effects of radiation emerging from shock-heated plasma in impact regions on the structure of the pre-shock downfalling material. We investigate if a significant absorption of radiation occurs and if it leads to a pre-shock heating of the accreting gas. We developed a radiation hydrodynamics model describing an accretion column impacting onto the surface of a Classical T Tauri Star. The model takes into account the stellar gravity, the thermal conduction, and the effects of both radiative losses and absorption of radiation by matter in the non local thermodynamic equilibrium regime. After the impact, a hot slab of post-shock plasma develops at the base of the accretion column. Part of radiation emerging from the slab is absorbed by the pre-shock accreting material. As a result, the pre-shock accretion column gradually heats up to temperatures of $10^5$ K, forming a radiative precursor of the shock. The precursor has a thermal structure with the hottest part at $T \approx 10^5$ K, with size comparable to that of the hot slab, above the post-shock region. At larger distances the temperature gradually decreases to $T \approx 10^4$ K.

description: In this article we explore some of the theoretical developments over the last 40 years which led to the emergence of the field of market design. This new field has had a substantive impact on policy, especially after the highly successful auctions of the mobile telephony licences in the mid-1990s in the US. The auctions replaced an inefficient allocation system where licences were allocated to applicants via a lottery and subsequently sold for large windfalls. These auctions raised substantial amount of revenue for the US government and were adopted worldwide, including in Australia. First, I provide a brief history of market design in cases where monetary payments can be used as the basis to allocate goods and services. This history starts with the game theoretical foundations of non-cooperative behaviour – as typically the interests of different individuals are in conflict, for example, when buying or selling goods and services – and then moves on to mechanism design and auction theory and practice. Second, I will review a very large experiment in Brazil where markets were created to avoid electricity rationing in 2001. The choice of this example is not inconsequential. It is meant to illustrate that such an approach to public policy can be successful even in developing countries with weaker institutions. I will then provide some concluding comments.

description: Since its discovery in the last century, quantum entanglement has challenged some of our most cherished classical views, such as locality and reality. Today, the second quantum revolution is in full swing and promises to revolutionize areas such as computation, communication, metrology, and imaging. Here, we review conceptual and experimental advances in complex entangled systems involving many multilevel quantum particles. We provide an overview of the latest technological developments in the generation and manipulation of high-dimensionally entangled photonic systems encoded in various discrete degrees of freedom such as path, transverse spatial modes or time/frequency bins. This overview should help to transfer various physical principles for the generation and manipulation from one to another degree of freedom and thus inspire new technical developments. We also show how purely academic questions and curiosity led to new technological applications. Here fundamental research provides the necessary knowledge for coming technologies such as a prospective quantum internet or the quantum teleportation of all information stored in a quantum system. Finally, we discuss some important problems in the area of high-dimensional entanglement and give a brief outlook on possible future developments.

Band structure, elementary excitations, and stability of a Bose-Einstein condensate in a periodic potential

description: We investigate the band structure of a Bose-Einstein condensate in a one-dimensional periodic potential by calculating stationary solutions of the Gross-Pitaevskii equation which have the form of Bloch waves. We demonstrate that loops ("swallow tails") in the band structure occur both at the Brillouin zone boundary and at the center of the zone, and they are therefore a generic feature. A physical interpretation of the swallow tails in terms of periodic solitons is given. The linear stability of the solutions is investigated as a function of the strength of the mean-field interaction, the magnitude of the periodic potential, and the wave vector of the condensate. The regions of energetic and dynamical stability are identified by considering the behavior of the Gross-Pitaevskii energy functional for small deviations of the condensate wave function from a stationary state. It is also shown how for long-wavelength disturbances the stability criteria may be obtained within a hydrodynamic approach.
