description: Free Standing Porous Graphene and Reduced Graphene Papers manufactured from Sedimentation of Arc Discharge of Graphite Rods. At SignEcoTech, novel and newer nano-carbons such as hard carbons, homogenized graphene, low defect highly crystalline graphene’s, and wrinkled graphene [1-14]. Here, Graphene Oxide papers have been synthesized previously by flow-directed assembly, where the pressure of air within the assembly supports graphene oxide sheets in their nano-crystalline colloidal solution being filtered on nano-porous filter paper. However in this research, we haven’t used any filter paper, or directed flow assembly, but sedimentation of the colloidal solution in ethyl alcohol in a dish. Then, the wrinkled the hierarchical GO sheets fall under gravity by sedimentation. Wrinkling in GO was enhanced by low defects, multi-layer clusters, and variegated + edge interaction amongst graphene clusters, as such the sedimented graphene papers were porous, intertwined and free standing. The composition of GO was confirmed by XPS, while the low defect level clearly marked by higher planar order and low ID/IG band. The wrinkled, multilayer clusters and carbonic surface properties of the graphene oxide sheets enhanced fast sedimentation, evaporation of the alcohol and formation of porous GO structure. The porous reduced\GO morphology is captured by optical microscope.

description: The main purpose of the study was to identify the plant genetic resources (PGRs) affected by shrimp farming and to determine their magnitude of vulnerability. Data were collected from randomly selected 100 respondents, through personal interview, using an interview schedule, at Dumuria upazila of Khulna district, during 16 November 2009 to 15 February 2010. The fruit PGRs were more affected by shrimp farming than that of timber yielding and other types of PGRs. Among the 18-fruit PGRs available, all were endangered, except indigenous velvet apple, Diospyros peregrine (Gaertn.) Gürke, which was in threatened condition. Among the fruit species, banana, Musa acuminate; guava, Psidium guajava L.; jackfruit, Artocarpus heterophyllus Lam.; sapota, Manilkara zapota L. and betel nut, Areca catechu L. were in highly endangered. Among the 17-timber yielding and other plant species, only 7-PGRs were affected by shrimp farming while majority (10-PGRs) had been available in different extents. Among the vulnerable PGRs, bamboo, Bambusa bambos (L.) Voss; flame of the forest, Delonix regia (Boj. ex Hook.) Raf.; teak, Tectona grandis L.f. and banyan, Ficus benghalensis L. were endangered, while Indian ash tree, Lannea coromandelica (Houtt.) Merr.; ipil-ipil, Leucaena leucocephala (Lam.) de Wit and cool mat, Schumannianthus dichotomus (Roxb.) Gagnep. were in threatened condition. In general, the total fruit trees decreased in numbers (-74.17%) after inception of shrimp farming. On the other hand, the total numbers of timber yielding plants increased by 15.45%. From the overall consideration (irrespective of types), the number of plant population decreased (-58.10%) after inception of shrimp farming. It means that the plant species were affected by shrimp farming and became endangered.

Production Economics

description: Expert analyses and forecasts of economic conditions are a compulsory basis of any appropriate development and policy making. They are necessary for the preparation of different expert economic and development documents as well as the continuous adaptation of economic and development policy measures to the changes in actual developments. The significance of forecasts is even greater if we take into account that they direct the economies into the desired direction by influencing the expectations and thereby the actual events. Of course, these are not forecasts in the classic meaning of the word but rather the most probable results of developments based on certain assumptions. The current agricultural policies play a special role in the development of single markets in agriculture. These policies are usually based on subsidies to agricultural producers. In the Common Agricultural Policy of the European Union, subsidies were until the last reform in 2003 in large part tied to some agricultural commodities and they thus distorted the free market solutions regarding the supply, demand and product prices. The producers were encouraged to preserve agricultural production and at the same time to produce certain commodities. They should directly contribute to greater economic activity. The situation has only started to change in the last few years, when market principles have also been increasingly applied to agriculture. We can use the production volume, the value of production, and income as measures of economic activity. Value added, which is the mathematical difference between the value of production in basic prices and the value of intermediate consumption, is used in the National Accounts.

description: Emotional content has complex effects on false memory. Under certain circumstances, emotional material may reduce the likelihood of false memory, a phenomenon that some consider related to it being more distinctive than neutral stimuli. In the present study we tested inferential false memory related to emotionally neutral or negative, and distinctive (but not emotionally charged) scripted material. Remember/familiar judgements were required for recognised stimuli. Data were analysed using mixed-effects multinomial regressions and a Bayesian inferential approach. Results obtained with 82 adult participants showed that, compared with neutral material: distinctive material reduced their false memory associated with “remember” and “familiar” judgements, virtually to the same extent; negatively-charged material reduced false memory associated with “remember” judgements but it had no effect on false memory associated with “familiar” judgements. In short, negatively-charged and distinctive material seems to affect false memory in different ways: the latter affects both recollection and familiarity, the former only recollection.

description: Dissipaton-equation-of-motion (DEOM) theory [Y. J. Yan, J. Chem. Phys. 140, 054105 (2014)] is an exact and nonperturbative many-particle method for open quantum systems. The existing dissipaton algebra treats also the dynamics of hybrid bath solvation coordinates. The dynamics of conjugate momentums remain to be addressed within the DEOM framework. In this work, we establish this missing ingredient, the dissipaton algebra on solvation momentums, with rigorous validations against necessary and sufficient criteria. The resulted phase-space DEOM theory will serve as a solid ground for further developments of various practical methods toward a broad range of applications. We illustrate this novel dissipaton algebra with the phase-space DEOM-evaluation on heat current fluctuation.

description: Given two sets of positive integers $A$ and $B$, let $AB := \{ab : a \in A,\, b \in B\}$ be their product set and put $A^k := A \cdots A$ ($k$ times $A$) for any positive integer $k$. Moreover, for every positive integer $n$ and every $α\in [0,1]$, let $\mathcal{B}(n, α)$ denote the probabilistic model in which a random set $A \subseteq \{1, \dots, n\}$ is constructed by choosing independently every element of $\{1, \dots, n\}$ with probability $α$. We prove that if $A_1, \dots, A_s$ are random sets in $\mathcal{B}(n_1, α_1), \dots, \mathcal{B}(n_s, α_s)$, respectively, $k_1, \dots, k_s$ are fixed positive integers, $α_i n_i \to +\infty$, and $1/α_i$ does not grow too fast in terms of a product of $\log n_j$; then $|A_1^{k_1} \cdots A_s^{k_s}| \sim \frac{|A_1|^{k_1}}{k_1!}\cdots\frac{|A_s|^{k_s}}{k_s!}$ with probability $1 - o(1)$. This is a generalization of a result of Cilleruelo, Ramana, and Ramaré, who considered the case $s = 1$ and $k_1 = 2$.

description: The super-AdS_5 X S^5 and the four-dimensional N=4 superconformal algebras play important roles in superstring theories. It is often discussed the roles of the osp(1|32) algebra as a maximal extension of the superalgebras in flat background. In this paper we show that the su(2,2|4), the super-AdS_5 X S^5 algebra or the superconformal algebra, is not a restriction of the osp(1|32) though the bosonic part of the former is a subgroup of the latter. There exist only two types of u(1) extension of the super-AdS_5 X S^5 algebra if the bosonic AdS_5 X S^5 covariance is imposed. Possible significance of the results is also discussed briefly.

description: We show that the Riccati form of the Schrodinger equation can be reformulated in terms of two linear equations depending on an arbitrary function G. When $G$ and the potential are polynomials, the solutions of these two equations are entire functions (L and K) and the zeroes of K are identical to those of the wave function. Requiring such a zero at a large but finite value of the argument yields the low energy eigenstates with exponentially small errors. Judicious choice of G can improve dramatically the numerical treatment. The method yields many significant digits with modest computer means.

description: This study focuses on determining whether violent contexts influence the perception of aggressiveness in faces analysing spontaneous corrugator supercilii activity. Participants viewed pictures of neutral and angry faces preceded by a contextual sentence describing either violent or neutral actions. They were instructed to judge each face according to whether it was aggressive or non-aggressive. Results show a higher level of perceived aggressiveness for neutral faces preceded by violent contexts, accompanied by longer reaction times, and a significant increase of corrugator activity. Angry faces preceded by neutral contexts were judged as less aggressive and elicited less corrugator activity. In conclusion, our results provide evidence that facial reactions and aggressiveness judgment for faces are context-dependent. With this work, we contribute to the view that contextual cues guide the face’s emotional meaning, under top-down processing.

description: A class of optical transients known as Luminous Red Novae (LRNe) have recently been associated with mass ejections from binary stars undergoing common-envelope evolution. We use the population synthesis code COMPAS to explore the impact of a range of assumptions about the physics of common-envelope evolution on the properties of LRNe. In particular, we investigate the influence of various models for the energetics of LRNe on the expected event rate and light curve characteristics, and compare with the existing sample. We find that the Galactic rate of LRNe is $\sim 0.2$ yr$^{-1}$, in agreement with the observed rate. In our models, the luminosity function of Galactic LRNe covers multiple decades in luminosity and is dominated by signals from stellar mergers, consistent with observational constraints from iPTF and the Galactic sample of LRNe. We discuss how observations of the brightest LRNe may provide indirect evidence for the existence of massive ($> 40$ M$_\odot$) red supergiants. Such LRNe could be markers along the evolutionary pathway leading to the formation of double compact objects. We make predictions for the population of LRNe observable in future transient surveys with the Large Synoptic Survey Telescope and the Zwicky Transient Facility. In all plausible circumstances, we predict a selection-limited observable population dominated by bright, long-duration events caused by common envelope ejections. We show that the Large Synoptic Survey Telescope will observe $20$--$750$ LRNe per year, quickly constraining the luminosity function of LRNe and probing the physics of common-envelope events.

description: The development of rural tourism is useful to both economic and social stability of rural areas along with employment, prevention of depopulation and migration to urban regions, preservation of values and tradition of rural life’s, the source of recreation and the way of healthy life. In order to develop it, it is necessary to determine the resources of the interested farms and to develop organizing skills of family farm members along with the creation of macro-environs that would provide support of business strategy towards development of rural tourism. Business farm adjustment is a process that depends on both internal and external environs that may direct diversification towards various types. For the last few years the importance of intensification and specialization of production has been emphasized by stimulating measures provided by the administration. Tendencies of the economic development require quite a different approach to rural areas in which not only the importance of primary agricultural production, but also economic and social prosperity of rural areas is stressed.

Goldstone modes in Lyapunov spectra of hard sphere systems

Subjects: subject: Chaotic Dynamics (nlin.CD)

description: In this paper, we demonstrate how the Lyapunov exponents close to zero of a system of many hard spheres can be described as Goldstone modes, by using a Boltzmann type of approach. At low densities, the correct form is found for the wave number dependence of the exponents as well as for the corresponding eigenvectors in tangent-space. The predicted values for the Lyapunov exponents belonging to the transverse mode are within a few percent of the values found in recent simulations, the propagation velocity for the longitudinal mode is within 1%, but the value for the Lyapunov exponent belonging to the longitudinal mode deviates from the simulations by 30%. For higher densities, the predicted values deviate more from the values calculated in the simulations. These deviations may be due to contributions from ring collisions and similar terms, which, even at low densities, can contribute to the leading order.

description: Spatial modes of light directly give the most easily accessible degree of freedom that span an infinite dimensional Hilbert space. The higher dimensional spatial mode entanglement realized using spontaneous parametric down conversion (SPDC) process is generally restricted to the subspace defined by a single spatial mode in pump. Access to other modal subspaces can be realized by pumping beams carrying several easily tunable transverse modes. As a proof-to-principle experiment, we generate twin-photon states in a nonlinear SPDC process with pump as a superposition of first order Laguerre-Gaussian (or Hermite-Gaussian) modes. We show that the generated states can be easily tuned between different subspaces by controlling the respective modal content in the pump superposition.

This upload contains the slides of the presentation of the break-out session on GDPR & Ethical Issues with Social Media Data. Data that can be collected from social media and other web platforms are currently being used as a new type of research data across academic disciplines, for example, to study online communication or to learn about users’ behavior or opinions. While the corresponding research area is growing, a lot of questions also about research methods and potential standards are arising, e.g., about representativeness and reproducibility. But discussions also increasingly focus on concerns about research ethics and data protection. A lot of this is work in progress and only a few standards or best practices for research designs or for documenting and sharing this type of research data exist. In this session, some of the key challenges related to questions of research ethics with a focus on data protection concerns in the area of social media as research data will be introduced. The session aims at providing some first insights for participants about critical questions when working with this new type of research data and point out useful resources as references.

description: Fuel wood provides the main source of energy for cooking and space heating for over 80 percent of households living in Kenya. The heavy reliance on the biomass energy has exerted an imbalance in demand and supply consequently resulting in adverse environmental effects in Kenya. As part of innovation efforts, several energy-conserving technologies have been developed. A unique cook stove named Maendeleo was developed and promoted in Kenya and more so, West Pokot County, northern of Kenya, with the goal of reducing the quantity of wood households use for energy, and ultimately reduce pressure on local forests. However, despite the demonstrated technological multiple benefits and the institutional promotional efforts of the Maendeleo stove technology; the adoption level of this innovation has remained low. An important question investigated in this study was what makes potential users not utilize such valuable innovations? Socio-cultural, economic, political and institutional barriers are considered to contribute to low uptake of such innovations. This study therefore, sought to assess socio- economic factors influencing the adoption of the Maendeleo stove in the rural setting of Kapenguria Division. A survey research methodology with ex-post facto design was employed. The results showed that the age of the respondents had the highest influence on the non-adoption of the Maendeleo stove. Given the relatively low adoption level of Maendeleo stove in the county, and the projected increase in the number of people relying on biomass, this study recommends that the government and development partners put in place a programme for the promotion and dissemination of Maendeleo stove. There should be further investigation into the adoption behaviour of the respondents on the reasons for non-adoption and discontinuance of use of the Maendeleo stove.

description: Focal adhesions are the loci of cellular adhesion to the extracellular matrix. At these sites, various integrins forge connections between the intracellular cytoskeleton and the outside world: large patches of multiple types of integrins together grip hold of collagen, fibronectin and other extracellular matrix components. The mixture of integrins composing the FA will, in general, contain both slip bond integrins and catch bond integrins---bonds whose lifetime increases with applied load and bonds for whom it decreases when forced. Prior work suggests that catch bonds are essential for proper FA stability and mechanosensory functionality. In the present work, we investigate, numerically, the interplay between the two distinct types of bonds and ask how the presence, in the same FA cluster, of slip bonds augments the behavior of the catch bonds. We show, that mixing the two components m low-force mechanical integrity, lacking in purely catch systems, while preserving the potential to strengthen the FA bond by force as well as the mechanosensory qualities of the catch bonds. We investigate the spatial distribution in mixed-integrin FA's and show that the differential response to loading leads, via an excluded volume interaction, to a dependence of the individual integrin diffusivities on the applied load, an effect that has been reported in experiments.

description: The heavy-fermion metal YbRh$_2$Si$_2$ realizes a field-induced quantum critical point with multiple vanishing energy scales $T_{\rm N}(B)$ and $T^\ast(B)$. We investigate their change with partial non-isoelectronic substitutions, chemical and hydrostatic pressure. Low-temperature electrical resistivity, specific heat and magnetic susceptibility of Yb(Rh$_{1-x}$T$_x$)$_2$Si$_2$ with T=Fe or Ni for $x\leq 0.1$, magnetic fields $B\leq 0.3$~T (applied perpendicular to the c-axis) and hydrostatic pressure $p\leq 1.5$~GPa are reported. The data allow to disentangle the combined influences of hydrostatic and chemical pressure, as well as non-isoelectronic substitution. In contrast to Ni- and Co-substitution, which enhance magnetic order, Fe-substitution acts oppositely. For $x=0.1$ it also completely suppresses the $T^\ast$ crossover and eliminates ferromagnetic fluctuations. The pressure, magnetic field and temperature dependences of $T^\ast$ are incompatible with its interpretation as Kondo breakdown signature.

description: We examined the hypothesis that boredom is likely to occur when opportunity costs are high; that is, when there is a high potential value of engaging in activities other than the researcher-assigned activity. To this end, participants were either placed in a room with many possible affordances (e.g. a laptop, puzzle, etc.; affordances condition; n = 121), or they were ushered into an empty room (control condition; n = 107). In both conditions participants were instructed to entertain themselves with only their thoughts (hence, participants in the affordances condition were to refrain from engaging with the available options). As predicted, participants in the affordances condition reported higher levels of boredom compared with those in the control condition. Results suggest that under some conditions, environments that afford alternative activities may be more boring than those that are void of such activities.

description: Objective: The objective of this study was to examine the influence of bicycle design and speed on the head impact when suffering from a single-bicycle crash, and the possibility to study this using crash tests. Methods: Simulations of single-bicycle crashes were performed in the VTI crash safety laboratory. Two bicycle crash scenarios were simulated: “a sudden stop” and “sideways dislocation of the front wheel”; using four different bicycle types: a “lady’s bicycle”, a commuter bicycle, a recumbent bicycle and a pedelec; at two speeds: 15 and 25 km/h. In addition, sideway falls were performed with the bicycles standing still. All tests were done with a Hybrid II 50th percentile crash test dummy placed in the saddle of the bicycles, with acceleration measurements in the head. Results: The crash tests showed that a sudden stop, e.g. a stick or bag in the front wheel, will result in a falling motion over the handle bars causing a forceful head impact while a sideways dislocation of the front wheel will result in a falling motion to the side causing a more moderate head impact. The falling motion varies between the different bicycle types depending on crash test scenario and speed. The pedelec had a clearly different falling motion from the other bicycle types, especially at a sudden stop. Conclusions: The study implies that it is possible to examine single-bicycle crashes using crash tests, even though the setup is sensitive to minor input differences and the random variation in the resulting head impact values can be large. Sideway falls with the bicycles standing still were easier to perform with a good repeatability and indicated an influence of seating height on the head impact.

description: Analysis of log data generated by online educational systems is an essential task to better the educational systems and increase our understanding of how students learn. In this study we investigate previously unseen data from Clio Online, the largest provider of digital learning content for primary schools in Denmark. We consider data for 14,810 students with 3 million sessions in the period 2015-2017. We analyze student activity in periods of one week. By using non-negative matrix factorization techniques, we obtain soft clusterings, revealing dependencies among time of day, subject, activity type, activity complexity (measured by Bloom's taxonomy), and performance. Furthermore, our method allows for tracking behavioral changes of individual students over time, as well as general behavioral changes in the educational system. Based on the results, we give suggestions for behavioral changes, in order to optimize the learning experience and improve performance.

description: We derive the global phase diagram of a self-gravitating $N$-body system enclosed in a finite three-dimensional spherical volume $V$ as a function of total energy and angular momentum, employing a microcanonical mean-field approach. At low angular momenta (i.e. for slowly rotating systems) the known collapse from a gas cloud to a single dense cluster is recovered. At high angular momenta, instead, rotational symmetry can be spontaneously broken and rotationally asymmetric structures (double clusters) appear.

description: We extend the cosmological predictions from assuming the total action of the universe is finite. When initial and final singularities in curvature invariants are avoided, it leads to singularities in the gravitational action of the universe. The following properties are required of a universe with finite action: Compact spatial sections (ie a closed universe) giving a finite total lifetime for the universe. Compactification of flat and open universes is excluded. The universe can contain perfect fluids with -12 in a closed, flat or open universe is excluded. Any bouncing model with indefinite past or future evolution is ruled out. Einstein static and steady-state universes are ruled out along with past or future eternal inflating universes. Anisotropies cannot dominate the dynamics at singularities. This excludes density inhomogeneity spectra versus mass, of the form δ\r{ho}/\r{ho}proportional to M^{-q}, with q>2/3.Higher-order lagrangian theories of gravity are constrained. The Gauss-Bonnet combination causes an action singularity even though it does not contribute terms to the field equations. Scalar-tensor theories dominated by the scalar field on approach to singularities have action singularities. Dark energy cannot be a cosmological constant. The dark energy must evolve in a closed universe that collapses to a future singularity that cannot be dominated by the kinetic energy of the scalar field.

description: We report experimental results on quasi-two-dimensional diffusion limited growth in directionally solidified succinonitrile with small amounts of poly(ethylene oxide), acetone, or camphor as a solute. Seaweed growth, or dense branching morphology, is selected by growing grains close to the $\{111\}$ plane, where the in-plane surface tension is nearly isotropic. The observed growth morphologies are very sensitive to small anisotropies in surface tension caused by misorientations from the $\{111\}$ plane. Different seaweed morphologies are found, including the degenerate, the stabilized, and the strongly tilted seaweeds. The degenerate seaweeds show a limited fractal scaling range and, with increased undercooling, suggests a transition from "fractal" to "compact" seaweed. Strongly tilted seaweeds demonstrate a significant twofold anisotropy. In addition, seaweed-dendrite transitions are observed in low anisotropy growth.

description: This paper examines the impact of the recent high taxation policy on Anatolian wine production as well as the value added loss from the use of grapes for non-wine consumption. The results clearly indicate that the high taxation policy is significantly reducing the wine production in Turkey. The suggested policy option of increasing the wine production may create six times more revenue than the existing policy outcome. A possible feasible policy is to remove the lump sum tax from exports and encourage export-oriented ‘Anatolian Old World’ wine.

description: We examine the impact of aging on wine prices and the performance of wine as a long-term investment, using a unique historical database for five long-established Bordeaux wines that we construct from auction and dealer prices. We estimate the life-cycle price patterns with a regression model that avoids multicollinearity between age, vintage year, and time by replacing the vintage effects with annual data on production yields and weather quality. In line with the predictions of an illustrative model, we observe the highest rates of appreciation for young high-quality wines that are still maturing. The findings suggest that the non-financial “psychic return” to holding wines that are substantially beyond maturity is at least 1%. Using an arithmetic repeat-sales regression, we estimate an annualized return to wine investments (net of insurance and storage costs) of 4.1%, in real GBP terms, between 1900 and 2012. Wine underperforms equities over this period, but outperforms government bonds, art, and stamps. Wine and equity returns are positively correlated.
