description: Frugale Innovationen werden oftmals in Verbindung mit Schwellenländern genannt, jedoch zeigen erste Studien, dass diese auch zunehmend an Relevanz in Industrienationen gewinnen. In diesem Arbeitspapier präsentieren wir die Ergebnisse verschiedener, durchgeführter Teilstudien zur Analyse der Innovationspfade in der deutschen Automobilzulieferindustrie und erläutern die Bedeutung frugaler Innovationen für die deutsche Automobilzulieferindustrie. Die deutsche Zulieferindustrie zeichnet sich insbesondere durch intensive Aktivitäten in den Bereichen Innovation sowie Forschung und Entwicklung aus. Der erste Teil der Forschungsarbeit beinhaltet eine umfangreiche Literaturanalyse und befasst sich mit der Durchführung von sechs Fallstudien sowie einer Patentanalyse zur Bestimmung der Innovationspfade und prägender Innovationsmerkmale. Die Fallstudien und die Patentanalyse beziehen sich auf den untersuchten Zeitraum von 2010 bis 2015. Der zweite Teil der Forschungsarbeit befasst sich mit der Validierung der Ergebnisse durch semistrukturierte Interviews. Hierzu wurden neun Experten mit insgesamt sechs unterschiedlichen Hintergründen befragt. Die Ergebnisse der Arbeit zeigen wichtige Einflussfaktoren auf die Innovationsaktivitäten auf und deuten darauf hin, dass die Frugalität in der deutschen Automobilzulieferindustrie eine durchaus wichtige Rolle einnimmt. Insbesondere sind hierbei die Erschwinglichkeit und die einfachere Gestaltung der Komponenten zu nennen. Die Aussagen der interviewten Industrieexperten stimmen mit diesen Ergebnissen überein und weisen auf das beachtliche Potential frugaler Innovationen in der deutschen Zulieferindustrie hin.

description: A simple design paradigm for making broad-band ultra-thin plasmonic absorbers is introduced. The absorber's unit cell is composed of sub-units of various sizes, resulting in nearly 100% absorbance at multiple adjacent frequencies and high absorbance over a broad frequency range. A simple theoretical model for designing broad-band absorbers is presented. It uses a single-resonance model to describe the optical response of each sub-unit and employs the series circuit model to predict the overall response. Validity of the circuit model relies on short propagation lengths of the surface plasmons.

description: We consider a possible ways of the dynamics of a homogeneous and isotropic space described by the FLRW metric in the framework of cubic f(R) gravity in the absence of matter. This article points an method for limiting the parameters of extended gravity models. We propose and develop a method for f(R) gravity models based on the dynamics of metrics for various model parameters in the simplest example. The influence of parameters and initial conditions on further dynamics are discussed. The parameters can be limited by 1) slow growth of space, 2) instability, 3) divergence with the inflationary scenario.

description: The aim of this review is to discuss the ways to obtain results based on gravity with higher derivatives in D-dimensional world. We considered the following ways: (1) reduction to scalar tensor gravity, (2) direct solution of the equations of motion, (3) derivation of approximate equations in the presence of a small parameter in the system, and (4) the method of test functions. Some applications are presented to illustrate each method. The unification of two necessary elements of a future theory is also kept in mind - the extra dimensions and the extended form of the gravity.

description: The conserved TOR signaling pathway links nutrient availability to cell, tissue and body growth in animals. One important downstream growth-regulatory effector of TOR is ribosome synthesis. Studies in yeast and mammalian cell culture have described how TOR controls rRNA synthesis - a limiting step in ribosome biogenesis - via the RNA Polymerase I transcription factor TIF-IA. However, the contribution of TOR-dependent ribosome synthesis to tissue and body growth in animals is less clear. Here I showed in Drosophila larvae that ribosome synthesis in muscle is required nonautonomously to maintain normal body growth and development. In addition, I found that amino acid starvation and TOR inhibition lead to reduced TIF-IA levels and decreased rRNA synthesis in the larval muscle. When I mimicked this decrease in muscle ribosome synthesis using RNAi-mediated knockdown of TIF-IA, I found delayed larval development and reduced body growth. This reduction in growth is caused by reduced systemic insulin signaling via two endocrine responses: First, reduced expression and release of Drosophila insulin-like peptides (dILPs) from the brain. Second, increased expression of Imp-L2 - a secreted factor, which binds and inhibits dILP activity from muscle. I also observed that maintaining TIF-IA levels in muscle could partially reverse the starvation-mediated inhibition of systemic insulin signaling. Finally, I showed that activation of TOR specifically in muscle can increase overall body size and this effect requires TIF-IA function. In contrast to muscle tissue, inhibition of ribosome synthesis in fat body modestly delayed development and had no effects on body growth. Moreover, the effect of ribosome synthesis inhibition in the fat body on developmental timing and body growth had weak effects on suppression of systemic insulin signaling. Overall, my data suggest that muscle ribosome synthesis functions as a nutrient-dependent checkpoint for overall body growth. Upon nutrient availability, TOR is required to maintain levels of TIF-IA and ribosome synthesis to keep high levels of systemic insulin. Conversely, upon starvation, muscle ribosome synthesis is reduced and triggers an endocrine response that limits systemic insulin signaling to restrict growth and maintain homeostasis.

description: The classification of imbalanced data has presented a significant challenge for most well-known classification algorithms that were often designed for data with relatively balanced class distributions. Nevertheless skewed class distribution is a common feature in real world problems. It is especially prevalent in certain application domains with great need for machine learning and better predictive analysis such as disease diagnosis, fraud detection, bankruptcy prediction, and suspect identification. In this paper, we propose a novel tree-based algorithm based on the area under the precision-recall curve (AUPRC) for variable selection in the classification context. Our algorithm, named as the "Precision-Recall Curve classification tree", or simply the "PRC classification tree" modifies two crucial stages in tree building. The first stage is to maximize the area under the precision-recall curve in node variable selection. The second stage is to maximize the harmonic mean of recall and precision (F-measure) for threshold selection. We found the proposed PRC classification tree, and its subsequent extension, the PRC random forest, work well especially for class-imbalanced data sets. We have demonstrated that our methods outperform their classic counterparts, the usual CART and random forest for both synthetic and real data. Furthermore, the ROC classification tree proposed by our group previously has shown good performance in imbalanced data. The combination of them, the PRC-ROC tree, also shows great promise in identifying the minority class.

description: The impressive and sustained growth of India's automobile industry in recent years has catapulted it into the league of the world's top-seven producers of four-wheelers. In the past decade, its exports have surged more than 25 percent a year on average. The turning point was arguably the 1991 policy of economic liberalization, but the impact of the reforms might have been subdued, if the Government of India had not played a pivotal role in the industry's evolution. This apparent "paradox" may be the key to understanding why the industry has adjusted so quickly to globalization, even though economic reforms began relatively late. This study identifies the main thrusts of policy regimes for the automobile sector since 1947, which began in an overregulation mode in the early period of independence. Nonetheless, the government consciously attempted to create and sustain favorable "innovation systems" at national, regional, and sectoral levels. Especially since 1991, many policy initiatives have benefited the industry and helped it reach the growth path it is following today.

description: Multichannel quantum defect theory (MQDT) can provide an efficient alternative to full coupled-channel calculations for low-energy molecular collisions. However, the efficiency relies on interpolation of the Y matrix that encapsulates the short-range dynamics, and there are poles in Y that may prevent interpolation over the range of energies of interest for cold molecular collisions. We show how the phases of the MQDT reference functions may be chosen so as to remove such poles from the vicinity of a reference energy and dramatically increase the range of interpolation. For the test case of Mg+NH, the resulting optimized Y matrix may be interpolated smoothly over an energy range of several Kelvin and a magnetic field range of over 1000 G. Calculations at additional energies and fields can then be performed at a computational cost that is proportional to the number of channels N and not to N^3.

description: The purpose of the current study is to enhance understanding of the neuropsychological basis of the social skill deficits in children with high-functioning autism spectrum disorders (HFASD) through an investigation of inhibition, a sub-domain of executive functioning. A total of 16 children with HFASD and 16 age- and gender-matched typically-developing (TD) comparison children were administered task-based measures of inhibition and were rated by parents on inhibition and social skills. Non-parametric statistical comparisons revealed that children with HFASD were rated as having poorer social skills and increased inhibitory dysfunction than their TD peers. Furthermore, this increased inhibitory dysfunction was negatively correlated with poorer social skills in the HFASD group only. The implications of these results are discussed in light of potential interventions and further understanding of the unique neuropsychological profile in children with HFASD. Finally, study limitations and suggestions for future research are highlighted.

description: We investigate the non-perturbative stability of asymptotically anti-de Sitter gravity coupled to tachyonic scalar fields with mass saturating the Breitenlohner-Freedman bound. Such "designer gravity" theories admit a large class of boundary conditions at asymptotic infinity. At this mass, the asymptotic behavior of the scalar field develops a logarithmic branch, and previous attempts at proving a minimum energy theorem failed due to a large radius divergence in the spinor charge. In this paper, we finally resolve this issue and derive a lower bound on the conserved energy. Just as for masses slightly above the BF bound, a given scalar potential can admit two possible branches of the corresponding superpotential, one analytic and one non-analytic. The key point again is that existence of the non-analytic branch is necessary for the energy bound to hold. We discuss several AdS/CFT applications of this result, including the use of double-trace deformations to induce spontaneous symmetry breaking.

description: Multiphase flows are commonly found in chemical engineering processes such as distillation columns, bubble columns, fluidized beds and heat exchangers. The physical boundaries of domains in numerical simulations of multiphase flows are generally defined by a conformal unstructured mesh which, depending on the complexity of the physical system, results in time-consuming mesh generation which frequently requires user-intervention. Furthermore, the resulting conformal unstructured mesh could potentially contain a large number of skewed elements, which is undesirable for numerical stability and accuracy. The diffuse-interface approach allows for the use of a simple structured meshes to be used while still capturing the desired physical (e.g., solid-fluid) boundaries. In this work, a novel diffuse-interface method for the imposition of physical boundaries is developed for the incompressible two-fluid multiphase flow model. This model is appropriate for dispersed multiphase flows which are pervasive in chemical engineering processes, in that this flow regime results in high levels of mass and energy transfer between phases. A diffuse interface is used to define the physical boundaries and boundary conditions are imposed by blending the conservation equations from the two-fluid model with that of the nondeformable solid. The results from the diffuse-interface method are compared with results from a conformal unstructured mesh for different interface functions and widths. For small interface widths, the accuracy of the flow profile is unaffected by the choice of interface function and the phase fraction distribution and flow behavior are within 3% compared to those from a conformal mesh. As the interface width increases, the diffuse-interface solution deviates from the conformal mesh solution in both the localized gas fraction and the overall gas hold-up, resulting in a difference up to 30%.

description: Recently published reports suggest the role of the muscles and tendons of the lower limbs are an important factor in determining the energy cost of running (Erun). Specifically, there exists a link between the mechanical properties of the Achilles tendon (AT) and Erun but the impact of the muscle’s energy cost is not considered. To date, very little is known regarding the interaction between AT stiffness, muscle energetics and Erun. Further, little is known about the AT stiffness- energetics relationship in female runners. Therefore, the overall goal of this thesis was to explore the relationship between AT stiffness and muscle energetics in male and female distance runners. The first study revealed AT stiffness of female runners was lower than in males, but Erun was similar to males. Further, the relationship between Erun and Achilles tendon stiffness was not different between the sexes. Results from the second study demonstrated that when reductions in AT stiffness were simulated, the rate of muscle energy use was elevated and the magnitude of muscle activation needed to reach a target force was increased. A novel method of assessing AT moment arm was assessed in study four. A key finding was that moment arm did not change through ankle range of motion. These results were used in the fifth study which demonstrated using estimates of muscle energetics, along with kinematics and kinetics during running that strain energy release from the AT during running was significantly lower than the muscle energy cost required for strain energy storage to occur. Lastly, using a prolonged run as an acute method of reducing AT stiffness, the impact of changes in AT stiffness during running on muscle energetics and Erun was evaluated. Results from this final study suggest that prolonged running reduces AT stiffness, the impact of which is an elevated muscle energy cost and increased whole-body Erun without a significant increase in estimated AT strain energy release. Together these findings support the notion that the role of the AT in running is to accommodate muscle-tendon unit length change, thereby reducing the amount of muscle fascicle shortening and therefore muscle energy cost.

description: In the context of quantum field theory, an anomaly exists when a theory has a classical symmetry which is not a symmetry of the quantum theory. This short exposition aims at introducing a new point of view, which is that the proper setting for anomaly calculations is the `in-in', or closed-time path formulation of quantum field theory. There are also some new results for anomalies in the context of boundary value problems, and a new correction to the $a_5$ heat-kernel coefficient.

description: Sum-based global tests are highly popular in multiple hypothesis testing. In this paper we propose a general closed testing procedure for sum tests, which provides lower confidence bounds for the proportion of true discoveries (TDP), simultaneously over all subsets of hypotheses. These simultaneous inferences come for free, i.e., without any adjustment of the alpha-level, whenever a global test is used. Our method allows for an exploratory approach, as simultaneity ensures control of the TDP even when the subset of interest is selected post hoc. It adapts to the unknown joint distribution of the data through permutation testing. Any sum test may be employed, depending on the desired power properties. We present an iterative shortcut for the closed testing procedure, based on the branch and bound algorithm, which converges to the full closed testing results, often after few iterations; even if it is stopped early, it controls the TDP. We compare the properties of different choices for the sum test through simulations, then we illustrate the feasibility of the method for high dimensional data on brain imaging and genomics data.

There are number of attacks on wireless sensor networks like black hole attack, sink hole attack, Sybil attack, selective forwarding attacks etc. in this paper we will concentrate on selective forwarding attacks In selective forwarding attacks, malicious nodes behave like normal nodes and selectively drop packets. The selection of dropping nodes may be random. Identifying such attacks is very difficult and sometimes impossible. In this paper we have listed up some detection techniques, which have been proposed by different researcher in recent years, there we also have tabular representation of qualitative analysis of detection techniques

Reactivity to stress and the cognitive components of math disability in grade 1 children
Creators: name: MacKinnon-McQuarrie, Maureen
Publisher: name: University of British Columbia
Year: 2010

description: This study investigated the relationship between working memory, processing speed, math performance and reactivity to stress in 83 grade 1 children, 39 with math disability (MD) in comparison to 44 typically achieving (TA) children. The purpose of this study was to investigate the cognitive components of MD and to determine whether stress was interfering with the processes believed to underlie MD. This study is the first to use a physiological index of stress (cortisol levels in saliva) to measure reactivity to stress and learning in children while completing tasks believed to underlie MD. The overall hypothesis was that children with high reactivity would perform more poorly on the working memory tasks believed to underlie MD and that children with MD and high reactivity would exhibit the poorest performance on the tasks that were impaired in children with MD. Nine tasks were administered to assess the core components of MD: working memory for numbers, working memory for words, digits backwards, letter number sequence, digit span forwards, processing speed for numbers and words, block rotation and math tasks. Saliva samples were collected for analysis of cortisol at Time 1 (Ti) as a pre-test baseline and Time 2 (T2) 30-minutes post-test as an index of stress. In addition, on a separate day, samples were collected Time 3 (T3) in the morning and Time 4 (T4) in the afternoon, to establish normal circadian rhythm. Participants were grouped by reactivity levels (high, moderate, and low) for effect size calculation. Children with MD were impaired on the Letter Number Sequence, and Quantitative Concepts tasks. Higher levels of reactivity significantly predicted poorer performance on the Working Memory for Numbers, Working Memory for Words, and Quantitative Concepts tasks. There were no differences between children with MD or TA in cortisol values at any of the times, in reactivity or circadian rhythm. The findings suggest that children with high reactivity may benefit from methods of emotional regulation to reduce reactivity, which may improve learning. Practical implications for educators include attention to the stress response in children, the identification of children with high reactivity and the provision of contextual support.
LexRank: Graph-based Lexical Centrality as Salience in Text Summarization

description: We introduce a stochastic graph-based method for computing relative importance of textual units for Natural Language Processing. We test the technique on the problem of Text Summarization (TS). Extractive TS relies on the concept of sentence salience to identify the most important sentences in a document or set of documents. Salience is typically defined in terms of the presence of particular important words or in terms of similarity to a centroid pseudo-sentence. We consider a new approach, LexRank, for computing sentence importance based on the concept of eigenvector centrality in a graph representation of sentences. In this model, a connectivity matrix based on intra-sentence cosine similarity is used as the adjacency matrix of the graph representation of sentences. Our system, based on LexRank ranked in first place in more than one task in the recent DUC 2004 evaluation. In this paper we present a detailed analysis of our approach and apply it to a larger data set including data from earlier DUC evaluations. We discuss several methods to compute centrality using the similarity graph. The results show that degree-based methods (including LexRank) outperform both centroid-based methods and other systems participating in DUC in most of the cases. Furthermore, the LexRank with threshold method outperforms the other degree-based techniques including continuous LexRank. We also show that our approach is quite insensitive to the noise in the data that may result from an imperfect topical clustering of documents.
AGROMIX – Introducing Policy Co-Development for Agroforestry and Mixed Farming
Creators: name: AGROMIX
Publisher: name: Zenodo

description: Mixed farming systems have been the predominant farming system in Europe for many centuries. However, the first mention of the word 'agroforestry' in policy documents of the EU's common agricultural policy (CAP) was only recently, in the 1998 EU forestry strategy (Larson et al. 2019). The first World Agroforestry Congress in Europe was only held in May 2019. Agroforestry as a mainstream land use has come to Europe late and spearheaded by pioneers like e.g. Martin Wolfe, the late Professor working at Coventry University and Wakelyns agroforestry (Wolfe and Pasiecznik, 2000). Den Herder et al. (2017) estimated the total area under agroforestry in the EU-27 about 15.4 million ha which is equivalent to about 8.8% of the utilised agricultural area (UAA). Over the last decades, structural changes in the EU agriculture have been reflected by declining number of farms, farm size growth and re-specialization of production, moving away from mixed farming (Neuenfeldt et al., 2018, EC Eurostat). The percentage of mixed farming of total agricultural holdings in EU-28 has decreased from 30% in 2005 to 21% in 2016 (EC Eurostat). With 8.8% of the UAA in Europe this is already a substantial area and currently more than the certified organic UAA. Although, certified organic farming is fast growing and likely to double in size in the next 20 years, it is not always, but mostly, mixed farming. In contrast, agroforestry within organic farms can be found more often but it is by no means exclusive to certified organic farming, or farming systems based on agroecological farming practices. Often low input farmers with mixed grazing or agroforestry (e.g. pasture feed beef, hay-milk systems, free-range chicken or agroforestry free-range pigs, chicken, sheep & beef,) are very close to organic management and could convert to organic farming quickly if the market can accommodate further organic produce. Therefore, both systems overlap and there are synergies which need to be considered in the policy work. Especially if another 10% of the UAA in Europe is converted to certified farming systems, including mixed farming and agroforestry in EU legislation regulating certified farming systems is one the policy options.

description: We demonstrate the suppression of nuclear spin fluctuations in an InAs quantum dot and measure the timescales of the spin narrowing effect. By initializing for tens of milliseconds with two continuous wave diode lasers, fluctuations of the nuclear spins are suppressed via the hole assisted dynamic nuclear polarization feedback mechanism. The fluctuation narrowed state persists in the dark (absent light illumination) for well over one second even in the presence of a varying electron charge and spin polarization. Enhancement of the electron spin coherence time (T2*) is directly measured using coherent dark state spectroscopy. By separating the calming of the nuclear spins in time from the spin qubit operations, this method is much simpler than the spin echo coherence recovery or dynamic decoupling schemes.
High-low temperature dualities for the classical $β$-ensembles

description: The loop equations for the $β$-ensembles are conventionally solved in terms of a $1/N$ expansion. We observe that it is also possible to fix $N$ and expand in inverse powers of $β$. At leading order, for the one-point function $W_1(x)$ corresponding to the average of the linear statistic $A = \sum_{j=1}^N 1/(x - λ_j)$, and specialising the classical weights, this reclaims well known results of Stieltjes relating the zeros of the classical polynomials to the minimum energy configuration of certain log-gas potential energies. Moreover, it is observed that the differential equations satisfied by $W_1(x)$ in the case of classical weights -- which are particular Riccati equations -- are simply related to the differential equations satisfied by $W_1(x)$ in the high temperature scaled limit $β= 2α/N$ ($α$ fixed, $N \to \infty$), implying a certain high-low temperature duality. A generalisation of this duality, valid without any limiting procedure, is shown to hold for $W_1(x)$ and all its higher point analogues in the classical $β$-ensembles.

description: Россия отличается высокой дифференциацией регионов по уровню социально-экономического и правового развития. Неравномерность развития предопределена разной степенью обеспечения различными ресурсами, исторически сложившейся инфраструктурой, климатическими условиями, обычаями и традициями коренного населения, уровнем правового образования населения, уровнем спроса и предложения на товары и услуги и многими другими факторами объективного и материального характера. Дифференциация регионов по уровню социально-экономического положения имеет место как среди федеральных округов, так и отдельных регионов внутри округов. В статье автором исследована роль и место регионов Уральского федерального округа в социально-экономическом положении округа. В основе использованы материалы рейтинга входящих в данный округ регионов, составленного Рейтинговым агентством «РИА-Рейтинг» с использованием комплекса показателей по итогам развития территорий за 2011 и 2018 годы.
description: The Russian Federation is characterized by a high differentiation of regions in terms of social, economic and legal development. Uneven development is determined by the different degree of provision of various resources, historical infrastructure, climatic conditions, customs and traditions of the indigenous population, the level of legal education of the population, the level of supply and demand for goods and services and many other factors of an objective and material nature. Differentiation of regions on the level of the social and economic situation takes place both among federal districts and individual regions within districts. The article investigates the role and place of the regions of the Ural Federal District in its social and economic situation. It is based on the rating materials of the district regions, conducted by the Rating Agency “RIA-Rating” using a set of indicators on the development results of territories in 2011 and 2018.

description: This paper investigates realisations of elliptic differential operators of general order on manifolds with boundary following the approach of Bär-Ballmann to first order elliptic operators. The space of possible boundary values of elements in the maximal domain is described as a Hilbert space densely sandwiched between two mixed order Sobolev spaces. The description uses Calderón projectors which, in the first order case, is equivalent to results of Bär-Bandara using spectral projectors of an adapted boundary operator. Boundary conditions that induce Fredholm as well as regular realisations, and those that admit higher order regularity, are characterised. In addition, results concerning spectral theory, homotopy invariance of the Fredholm index, and well-posedness for higher order elliptic boundary value problems are proven.

description: La riduzione del paradigma flessionale del portoghese brasiliano (d’ora in poi PB) ha avuto come conseguenza il fatto che oggigiorno il PB, nella sua varietà neostandard, non possa essere più considerato una (varietà di) lingua a soggetto nullo e debba, invece, considerarsi  una (varietà di) lingua a soggetto parzialmente espresso, dato che, nonostante la perdita di soggetti nulli referenziali, presenta ancora contesti di resistenza al cambiamento, in cui è tuttora possibile l’omissione di soggetti referenziali (soprattutto alla 3 persona del discorso). La presente comunicazione si pone l’obiettivo di osservare tale cambiamento parametrico, analizzando, in modo comparatistico, il romanzo testimoniale Estive em Lisboa e lembrei de você (2009), di Luiz Ruffato, e il parlato filmico dell’omonima trasposizione filmica diretta da José Barahona, nel 2015. Nondimeno, è d’uopo evidenziare che i risultati di tale riflessione non possono essere considerati alla stregua di dati empirici da cui trarre delle considerazioni sul parlato spontaneo in situazione, ma possono aiutare a comprendere come fattori extralinguistici come il genere discorsivo e la tipologia testuale possano influire sulla realizzazione della struttura linguistica del dialogo letterario e, in casi di trasposizione intersemiotica, di quella del parlato filmico.

description: The ability to follow the dynamics of a quantum system in a quantitative manner is of key importance for quantum technology. Despite its central role, justifiable deduction of the quantum dynamics of a single quantum system in terms of a macroscopical observable remains a challenge. Here we show that the relation between the readout signal of a single electron spin and the quantum dynamics of the single nuclear spin is given by a parameter related to the measurement strength. We determine this measurement strength in independent experiments and use this value to compare our analysis of the quantum dynamics with experimental results. We prove the validity of our approach by measuring violations of the Leggett-Garg inequality.

description: This article gives a survey of recent results on a generalization of the notion of a Hodge structure. The main example is related to the Fourier-Laplace transform of a variation of polarizable Hodge structure on the punctured affine line, like the Gauss-Manin systems of a proper or tame algebraic function on a smooth quasi-projective variety. Variations of non-commutative Hodge structures often occur on the tangent bundle of Frobenius manifolds, giving rise to a tt* geometry.

Self-sustained wormholes in modified dispersion relations

description: In this work, we consider the possibility that wormhole geometries are sustained by their own quantum fluctuations, in the context of modified dispersion relations. More specifically, the energy density of the graviton one-loop contribution to a classical energy in a wormhole background is considered as a self-consistent source for wormholes. In this semi-classical context, we consider specific choices for the Rainbow's functions and find solutions for wormhole geometries in the cis-planckian and trans-planckian regimes. In the former regime, the wormhole spacetimes are not asymptotically flat and need to be matched to an exterior vacuum solution. In the latter trans-planckian regime, we find that the quantum corrections are exponentially suppressed, which provide asymptotically flat wormhole geometries with a constant shape function, i.e., b(r)=r_t, where r_t is the wormhole throat. In addition to this analysis, we also fix the geometry by considering the behaviour of a specific shape function through a variational approach which imposes a local analysis to the problem at the wormhole throat. We further explore the respective parameter range of the Rainbow's functions, and find a good agreement with previous work.
