description: We investigate the spectral stability of travelling wave solutions in a Keller-Segel model of bacterial chemotaxis with a logarithmic chemosensitivity function and a constant, sublinear, and linear consumption rate. Linearising around the travelling wave solutions, we locate the essential and absolute spectrum of the associated linear operators and find that all travelling wave solutions have essential spectrum in the right half plane. However, we show that in the case of constant or sublinear consumption there exists a range of parameters such that the absolute spectrum is contained in the open left half plane and the essential spectrum can thus be weighted into the open left half plane. For the constant and sublinear consumption rate models we also determine critical parameter values for which the absolute spectrum crosses into the right half plane, indicating the onset of an absolute instability of the travelling wave solution. We observe that this crossing always occurs off of the real axis.

description: The FAIR Earth Sciences & Environment services (FAIR-EASE) project aims to customise and operate distributed and integrated services for observation and modelling of the Earth system, environment and biodiversity by improving the Technology Readiness Level (TRL) of their different components implemented in close cooperation with user-communities, the European Open Science Cloud (EOSC) and research infrastructures in their design and sustainable availability. To achieve this goal, the project will improve data discovery and access and will create an Earth Analytical Lab offering web-based interfaces, predefined processing tools and on-demand data visualisation services for remote analysis and processing of heterogeneous data (see 2.4. Key Assets & Value Proposition). An essential step will be the Dissemination, Exploitation, and Communication Plan aimed at guaranteeing a significant uptake of the developed solution. The overarching dissemination, communication and exploitation goal is to ensure the maximum uptake and adoption of the project’s results. The communications and dissemination activities will target each of the identified stakeholder groups which include Policy Makers, Resource Providers and Operational Forecast Services, EOSC Ecosystem, Civil Society and General Public and Research User Community (see 2.6. Stakeholder Analysis). To ensure sufficient result exploitation, the applied methodology will include the generation of relevant content for each stakeholder group and their engagement as community members. Some of the tools that will be used include newsletters, social media schedulers, event tools, webinar videoconferencing tools. The communications activities will be continuously monitored by such tracking tools as Google Analytics and the Drupal content management tracker, among others (see 2.3. Monitoring). The communications and dissemination will be multi-channel and consist of horizontal activities (see 2. Communication and Dissemination Strategy). The channels for horizontal activities will include the support of the website with an overview of the FAIR-EASE functionalities, social media, content repositories, physical and digital graphically designed communication materials, videos, a newsletter, press releases, and third-party coverage that will ensure a multi-media approach to communication & dissemination. Concurrently, FAIR-EASE will organise at least five webinars within the time span of the project. The preliminary exploitation measures have been considered, but both stakeholder feedback and the maturing of the project Key Exploitable Results (KERs) will inform the development of the exploitation plan which will be updated in the further iterations of this Deliverable.
Is What Scientists Say Always Best? Reflecting on the Role of Perinatal and Infant Experts’ Knowledge in the Cultures, Policies and Practices of Parenthood

description: Reviewing recent literature on the topic, this article reflects from a sociological perspective on the influence that perinatal and infant experts’ authority and scientific knowledge have on the cultures, policies and practices of parenthood in contemporary societies. Here the author refers mainly to the heterosexual parenthood and not also to the homogenitorial families that would require a separate discussion. The geographical and social context the author refers to is mainly Italy. After having illustrated the main characteristics of the “expert-led” model in perinatal and infant area and the reasons why it has become increasingly the hegemonic model in the parenting and childrearing cultures and practices, the article presents an overview of the Italian context illustrating data on pregnancy, childbirth, breastfeeding and vaccination. Then it questions about possible research developments in exploring the use that the policy makes of the experts’ knowledge and scientific evidence and the implications of this use. Finally it reflects on the growing diffusion of anti-science movements in perinatal and infant area.

description: We theoretically investigate the stability of a two cascaded cavity optomechanical system with optical parametric amplifiers (OPAs) inside the two coupled cavities, and study the steady-state entanglement between two distant mechanical resonators. We show that the parameter regime where the system is unstable without OPAs, such as relatively high laser intensity and blue detuning, can be exploited to build the steady-state mechanical entanglement by modulating the parametric gain. The application of OPAs is helpful to preserve the mechanical entanglement suffered from the dissipation at some finite temperature. The scheme provides an alternative way for improving and engineering the quantum entanglement of two distant mechanical oscillators.

Effects of Design Parameters on Curved Ballasted Track
Creators: name: Yonatan, Abebe
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: Train and track interactions during services normally generate substantial forces on railway tracks. Such forces are transient by nature and of relatively large magnitude. There has been small literature showing of the typical responses for the loading conditions on the curved section of railway track structures, in particular, lateral and vertical loads. This paper presents a response of the curved section of a ballasted railway track structure for different parameters of track and train. In this research, the response of curved ballasted track components as a function of speed, cant and curvature is investigated using numerical modeling. Curved and straight section of ballasted railway track is modeled using the finite element approach. The paper mainly focuses on studying the effect of speed, cant as well as curvature on the values of deformation/displacement of the components of the track . Taking into account a model representing the train load, the model forms a dynamic analysis and a non-linear quasi-static analysis of track structures using Finite Element Modeling method with the use of commercially available software ABAQUS. The main results that are used to investigate the effect of speed, cant and curvature are vertical and lateral rail deflection, vertical and lateral sleeper displacement and vertical and lateral subgrade displacement Hertz analytical method was used to assess the axle load and train speed effect based on the results of calculated contact pressure and penetration depths for a selected straight section where the half-space assumption is valid. Results show that with increasing train speed track deflection grow higher. It is observed that, for example, in a long-term the outer rail response for a 350 meter radius ballasted track there is 0.3536 mm lateral deflection increase for every Km/hr increase of train speed. It is recommended to do a feed-back loop for the long-term behavior of the track.

description: Telling the work today, implies undeniably, to consider the relationship between production, science, technology and information society. In this context, How is the work told today? Who does it and how? This contribution attempts to answer these questions, narrowing the field of observation to the digital work of the Labor Platform, in relation to the ILO notion of decent work. It focuses, therefore, on the public discourse present in the scientific, political and information debate on digital work. In this context, the article, using Laclau’s interpretation on populism and in particular using his Theory of Speech, highlights as within what can be considered a distance between science, institutions and work can act a populist representation of the social identities of precarious work.

description: Penrose proposed that the big bang singularity should be constrained by requiring that the Weyl curvature vanishes there. The idea behind this past hypothesis is attractive because it constrains the initial conditions for the universe in geometric terms and is not confined to a specific early universe paradigm. However, the precise statement of Penrose's hypothesis is tied to classical space-times and furthermore restricts only the gravitational degrees of freedom. These are encapsulated only in the tensor modes of the commonly used cosmological perturbation theory. Drawing inspiration from the underlying idea, we propose a quantum generalization of Penrose's hypothesis using the Planck regime in place of the big bang, and simultaneously incorporating tensor as well as scalar modes. Initial conditions selected by this generalization constrain the universe to be as homogeneous and isotropic in the Planck regime \emph{as permitted by the Heisenberg uncertainty relations}.

description: Within the present study, the effects of fermentation on the anti-inflammatory and anti-platelet properties of both homemade and commercially purchased bovine dairy and almond, coconut, and rice-based dairy alternatives were evaluated. The extracted total lipids (TL) from homemade and commercially purchased fermented and unfermented bovine, almond, coconut, and rice-based products were further separated into their neutral lipids (NL) and polar lipids (PL) fractions by counter current distribution. The TL, PL, and NL of each sample were assessed in human platelets against the inflammatory and thrombotic mediator, platelet-activating factor (PAF), and the well established platelet agonist, adenosine 50 diphosphate (ADP). In all samples, the PL fractions showed significantly stronger inhibitory effects against human platelet aggregation induced by PAF or ADP, in comparison to the TL and NL, with higher specificity against PAF. PL of all fermented products (bovine yogurt and fermented dairy alternatives from almond, rice, and coconut), exhibited the strongest anti-inflammatory and anti-platelet potency, in comparison to PL from their initial pasteurized materials (bovine milk and rice, almond, and coconut-based dairy alternative drinks). PL of the pasteurized rice-based drink and, especially PL from the novel homemade rice-based fermented product (HMFRD), showed the strongest anti-PAF and anti-ADP potency compared to all samples, with anti-PAF activity being most potent overall. The unfermented pasteurized coconut?based drink showed the lowest anti-inflammatory and anti-platelet potency, and the bovine and almond-based fermented products showed an intermediate effect. Further lipidomics with LC-MS analysis of all these PL fractions revealed that fermentation altered their fatty acid content in a way that decreased their degree of saturation and increased the content of unsaturated fatty acids, thus providing a rationale for the stronger anti-inflammatory and anti-platelet potency of the more unsaturated PL fractions of the fermented products. This study has shown that fermentation alters the fatty acid content and the bio-functionality of the PL bioactives in both fermented bovine dairy and plant-based dairy alternatives, and subsequently improved their anti-inflammatory and anti-platelet functional properties.

description: The internet of things (IoT) has gained worldwide attention in recent years. It transforms the everyday objects that surround us into proactive actors of the Internet, generating and consuming information. An important issue related to the appearance of such large-scale self-coordinating IoT is the reliability and the collaboration between the objects in the presence of environmental hazards. High failure rates lead to significant loss of data. Therefore, data survivability is a main challenge of the IoT. In this paper, we have developed a compartmental e-Epidemic SIR (Susceptible-Infectious-Recovered) model to save the data in the network and let it survive after attacks. Furthermore, our model takes into account the dynamic topology of the network where natural death (crashing nodes) and birth are defined and analyzed. Theoretical methods and simulations are employed to solve and simulate the system of equations developed and to analyze the model.

description: TOPAZ4 and neXtSIM sea ice drift forecast model data, provided in the CMEMS artic analysis and forecast products PHYS_002_001_a and PHY_ICE_002_011, is assessed using Sentinel-1 Synthetic Aperture Radar (SAR) image pairs. This work helps to improve the high-resolution forecast Predictive Ice Image (PRIIMA) (https://business.esa.int/projects/priima) application which generates multi-day forecasted SAR scenes. Results of PRIIMA form the basis for the calculation of possible ship routes in ice-infested waters, which are then made accessible for navigators in near real-time. The true sea ice drift is derived from two successive Sentinel-1 scenes using phase correlation applied in a hierarchical resolution pyramid. The measured ice displacement vectors are compared to predicted drift trajectories derived from multi-day TOPAZ4 and neXtSIM forecasts available at acquisition time of the first SAR scene. Differences in sea ice drift direction and magnitude between models and actual SAR measurements are then analysed visually and statistically. A feature-based approach of data handling enables the comparison of drift data stored in vector format and model data stored in raster format. The analysis benefits from the high coordinate precision of vector models and a fine granularity of a grid spacing down to 500 m. This initial study focuses on time differences of 1 to 3 days in two regions of interest (RIOs). The first ROI is located offshore close to Cape Morris Jesup at the transition between Lincoln and Wandel Sea. The second ROI is placed at open sea above Alpha Ridge near Ellesmere Island. A small initial sample of seven image pairs is analysed to test the approach, from which some preliminary conclusions can already be drawn: The root-mean-square separation distance between the end points of the measured drift vectors and the derived model trajectories (RMS separation distance) is around 4 to 5 km per day for both TOPAZ and neXtSIM. The RMS separation distance shows a high variability across the investigated image pairs. In the first ROI, a high RMS separation distance in the neXtSIM model was found near Cape Morris Jesup in the case of coastward drift or drift around the cape. In future works, the conducted analysis will be extended to a one-year analysis in selected regions arctic wide, taking into consideration the influences of sea ice deformation, atmosphere and ocean.

description: We present an existence and stability theory for gravity-capillary solitary waves on the top surface of and interface between two perfect fluids of different densities, the lower one being of infinite depth. Exploiting a classical variational principle, we prove the existence of a minimiser of the wave energy $\mathcal{E}$ subject to the constraint $\mathcal{I}=2μ$, where $\mathcal{I}$ is the wave momentum and $0< μ< μ_0$, where $μ_0$ is chosen small enough for the validity of our calculations. Since $\mathcal{E}$ and $\mathcal{I}$ are both conserved quantities a standard argument asserts the stability of the set $D_μ$ of minimisers: solutions starting near $D_μ$ remain close to $D_μ$ in a suitably defined energy space over their interval of existence. The solitary waves which we construct are of small amplitude and are to leading order described by the cubic nonlinear Schrödinger equation. They exist in a parameter region in which the `slow' branch of the dispersion relation has a strict non-degenerate global minimum and the corresponding nonlinear Schrödinger equation is of focussing type. We show that the waves detected by our variational method converge (after an appropriate rescaling) to solutions of the model equation as $μ\downarrow 0$.

description: We have developed the deposition technology of WSi thin films 4 to 9 nm thick with high temperature values of superconducting transition (Tc~4 K). Based on deposed films there were produced nanostructures with indicative planar sizes ~100 nm, and the research revealed that even on nanoscale the films possess of high critical temperature values of the superconducting transition (Tc~3.3-3.7K ) which certifies high quality and homogeneity of the films created. The first experiments on creating superconducting single-photon detectors showed that the detectors SDE (system detection efficiency) with increasing bias current (Ib) reaches a constant value of ~30% (for 1550 nm) defined by infrared radiation absorption by the superconducting structure. To enhance radiation absorption by the superconductor there were created detectors with cavity structures which demonstrated a practically constant value of quantum efficiency >65% for bias currents Ib>=0.6Ic. The minimal dark counts level (DC) made 1 s^-1 limited with background noise. Hence WSi is the most promising material for creating single-photon detectors with record SDE/DC ratio and noise equivalent power (NEP).

description: The massive diffusion of online social media allows for the rapid and uncontrolled spreading of conspiracy theories, hoaxes, unsubstantiated claims, and false news. Such an impressive amount of misinformation can influence policy preferences and encourage behaviors strongly divergent from recommended practices. In this paper, we study the statistical properties of viral misinformation in online social media. By means of methods belonging to Extreme Value Theory, we show that the number of extremely viral posts over time follows a homogeneous Poisson process, and that the interarrival times between such posts are independent and identically distributed, following an exponential distribution. Moreover, we characterize the uncertainty around the rate parameter of the Poisson process through Bayesian methods. Finally, we are able to derive the predictive posterior probability distribution of the number of posts exceeding a certain threshold of shares over a finite interval of time.
How the conflict-related sexual violence is addressed by the International Criminal Court?

Subjects: conflict-related sexual violence, International Criminal Court, efficiency, prosecution, impediments to justice

description: There has been a long-standing criticism in legal literature about the fact that the system of international criminal justice has never paid enough attention to gender-related crimes, in particular conflict-related sexual violence. This criticism is particularly strong in relation to the International Criminal Court, which, notwithstanding its resources and opportunities, has barely ever touched the subject. The poster will explore the issue of whether the prosecution of sexual violence crimes by the International Criminal Court is effective enough per se and compared to other crimes within the jurisdiction of the Court, and also why such crimes deserve special attention and proper handling by the ICC.

description: BACKGROUND: Obstetric fistula although is eliminated in high income countries, it remains prevalent and debilitating condition in many parts of the developing world leaving women with the immediate consequences, such as leakage of urine or feces or both and has been observed since women first began delivering children despite of the fact that it is completely preventable if high quality basic and comprehensive maternal health services are available to all woman during pregnancy and childbirth by a well-trained and knowledgeable skilled birth attendants. OBJECTIVE: The objective of this study was to assess knowledge and practice on prevention of Obstetric Fistula among skilled birth attendants in public Health Centers in Addis Ababa. METHODS: Institutional based Quantitative Cross sectional study was undertaken in public health centers in Addis Ababa. A multi staged systematic random sampling technique was implemented to select a total of 548 skilled birth attendants. The data was collected by using self-administered questionnaire prepared in English language from March–April 2016 after ensuring that all requirement of Ethical consideration is fulfilled. The collected data was cleaned, entered and analyzed using SPSS Version 20. Odds ratios with 95 % confidence interval with binary logistic regression model was used to measure the association of dependent and independent variables. Descriptive statistics with frequency and percentages, table's graphs and cross-tabulations was used. Results: This study revealed that 67% of skilled birth attendants had good knowledge on prevention of obstetric fistula and in-service training related to obstetric fistula (AOR =1.53, 95% CI 1.04-2.25), resource availability (AOR =2.78, 95% CI 1.46-5.28) and service year (AOR =1.90, 95% CI 1.08-3.36) were significantly associated. About 66.2% of skilled birth attendants had good practice. Diploma nurses and degree nurses were less likely to have good practice as compare to Diploma midwives. (AOR =0.41, 95% CI 0.23-0.74; AOR =0.29, 95% CI 0.16-0.56) respectively. Pre-service training (AOR =2.19, 95% CI 1.48-3.24), in-service training (AOR =1.59, 95% CI 1.05-2.39), resource availability (AOR =2.85, 95% CI 1.44-5.65), and knowledge (AOR =2.47, 95% CI 1.65-3.68) were other factors independently associated with practice on prevention of obstetric fistula. Conclusion and recommendation: In conclusion majority of skilled birth attendants were found to have good knowledge and good practice towards prevention of Obstetric Fistula. Obstetric Fistula should be adequately addressed for health students during their pre-service training and training regarding Obstetric Fistula and related issues should also be given for skilled birth attendants. Key word: Obstetric Fistula Prevention, Skilled birth attendants

description: Initial-boundary value problems for 1-dimensional `completely integrable' equations can be solved via an extension of the inverse scattering method, which is due to Fokas and his collaborators. A crucial feature of this method is that it requires the values of more boundary data than given for a well-posed problem. In the case of cubic NLS, knowledge of the Dirichet data suffices to make the problem well-posed but the Fokas method also requires knowledge of the values of Neumann data. The study of the Dirichlet to Neumann map is thus necessary before the application of the `Fokas transform'. In this paper, we provide a rigorous study of this map for a large class of decaying Dirichlet data. We show that the Neumann data are also sufficiently decaying and hence that the Fokas method can be applied. For simplicity we considered here the case of zero initial data. An addendum will follow, discussing the case of non-zero initial data.

description: One of the strengths of quantum information theory is that it can treat quantum states without referring to their particular physical representation. In principle, quantum states can be therefore fully swapped between various quantum systems by their mutual interaction and this quantum state transfer is crucial for many quantum communication and information processing tasks. In practice, however, the achievable interaction time and strength are often limited by decoherence. Here we propose and experimentally demonstrate a procedure for faithful quantum state transfer between two weakly interacting qubits. Our scheme enables a probabilistic yet perfect unidirectional transfer of an arbitrary unknown state of a source qubit onto a target qubit prepared initially in a known state. The transfer is achieved by a combination of a suitable measurement of the source qubit and quantum filtering on the target qubit depending on the outcome of measurement on the source qubit. We experimentally verify feasibility and robustness of the transfer using a linear optical setup with qubits encoded into polarization states of single photons.

description: Merging neutron star binaries are prime candidate sources for heavy r-process nucleosynthesis. The amount of heavy r-process material is consistent with the mass ejection and rates of mergers, and abundances of relic radioactive materials suggest that heavy r-process material is produced in rare events. Observations of possible macronovae provide further support for this model. Still, some concerns remain. One is the observation of heavy r-process elements in Ultra Faint Dwarf (UFD) galaxies. The escape velocities from UFDs are so small that the natal kicks, taking place at neutron stars birth, might eject such binaries from UFDs. Furthermore the old stellar populations of UFDs requires that r-process nucleosynthesis must have taken place very early on, while it may take several Gyr for compact binaries to merge. This last problem arises also within the Milky Way where heavy r-process materials has been observed in some low metallicity stars. We show here that since a significant fraction of neutron star binaries form with a very small proper motion those won't be ejected even from a UFD. Furthermore, a significant fraction of these binaries merge within a few hundred Myr and in some cases the merger time is even shorter than a hundred Myr. This population of "rapid mergers" explains the appearance of heavy r-process material in both UFDs and in the Milky Way.

description: Background Malnutrition remains one of the most common causes of morbidity and mortality among children throughout the world. It is responsible about 60% cause of death in under age of 5 years. Objective To assess feeding practice and factors associated with severe acute malnutrition in under age of 5 year children admitted to Addis Ababa Government Hospitals, Ethiopia, 2014. Methods and Materials A cross sectional study design was conducted on 151 under age of 5 year children admitted to Addis Ababa Governmental Hospitals from April to May 2014. The required number of sample was selected based on the registration and diagnosis. Data was collected by review of medical records and interview of the family member nearby during data collection. The data was manipulated and analyzed by using Epi.info version 3.5.4 for windows and SPSS version 16.0. Results Out of one hundred fifty one study subjects, 124(82.1%) of them breastfed; but majority of them, 65.4% did not practice exclusive breast feeding. Maternal illiteracy had 2.46 times high risk and significant association with severe acute malnutrition (AOR=2.46, 95% CI, 1.4-42.4). Being age younger than 11 months also showed 5.97 times high risk and statistically significant association with severe acute malnutrition (AOR=5.97, 95% CI, 1.8-20). Children of governmental employee mother were 2.29 times high risk to be affected by marasmus (AOR=2.29, 95% CI, 1.4–3.86). Male children were 2.28 times higher risk to be affected by the case than female children (AOR= 2.28, 95% CI, 1.1–4.9) Conclusion Maternal illiteracy, maternal occupation, sex of the child being male and age of the child younger than 11 months have strong and statistically significant association with child severe acute malnutrition. Recommendation I would like to recommend Ministry of Health, Ministry of Education and Addis Ababa Health Bureau to strengthen maternal education in order to improve the knowledge and practice of parents on appropriate infant and young child feeding practices.

description: For the moduli space of Higgs bundles on a Riemann surface of positive genus, critical points of the natural Morse-Bott function lie along the nilpotent cone of the Hitchin fibration and are representations of $\mbox{A}$-type quivers in a twisted category of holomorphic bundles. The critical points that globally minimize the function are representations of $\mbox{A}_1$. For twisted Higgs bundles on the projective line, the quiver describing the bottom of the cone is more complicated. We determine it here. We show that the moduli space is topologically connected whenever the rank and degree are coprime, thereby verifying conjectural lowest Betti numbers coming from high-energy physics.

description: Information matters to the railway's customers; it is a common phenomenon in many countries which is also significant problem in AALRT. It always determines the quality of the transportation system. Therefore designing passenger information system is necessary to realize transportation quality, safety and reliability. In this paper the design of passenger information system is presented (possibly) the design was implemented using the platform. For the design of this system three modules which are global positioning system train locator unit, central control system (central server), and passenger information display unit will be used. It uses global positioning system technology to collect the real time information about the train including vehicle location, direction, speed and others. Global system for mobile telecommunication module is used for data transmission between central command and moving train. A passenger information system (PIS), fixed at station provide real-time passenger information it received from the central server to a passenger at stations. It may include present location, time to reach the platform, delay time, train space, updated schedule and safety information. Finally it is expected that this system will provide information to passengers with a little delay and a better accuracy in local language.
The Essence of Gravitation and the Power of Cosmic expansion

description: Why all things attract each other, what is the essence of gravitation, why the universe constantly expands, what is the power of the expansion of the universe? These problems have been perplexing the scientific community. The explanation of gravity in general relativity is not perfect and the theory does not explain the physical meaning of the gravitational constant G. Scientists use dark energy to explain the expansion of the universe, but there is no clear answer to what dark energy is. Based on the scientific achievements of The Big Bang Theory, quark model and Parton model, this paper puts forward the theory of fluid gravity, deduces a new gravity formula, and reveals the essence of universal gravity and the driving force of cosmic expansion. The fluid gravity formula can be transformed into Newton's gravity formula. It is concluded that the gravity constant G is a slowly changing quantity, the gravity of celestial bodies is limited and may not form a real black hole, and the current total density of the universe is greater than the critical density. The theory predicts that gravity can be partially shielded. Chinese version DOI:https://doi.org/10.55375/preprints.2022.1.4

description: Long-range spatial correlations in the velocity and energy fields of a granular fluid are discussed in the framework of a 1d lattice model. The dynamics of the velocity field occurs through nearest-neighbour inelastic collisions that conserve momentum but dissipate energy. A set of equations for the fluctuating hydrodynamics of the velocity and energy mesoscopic fields give a first approximation for (i) the velocity structure factor and (ii) the finite-size correction to the Haff law, both in the homogeneous cooling regime. At a more refined level, we have derived the equations for the two-site velocity correlations and the total energy fluctuations. First, we seek a perturbative solution thereof, in powers of the inverse of system size. On the one hand, when scaled with the granular temperature, the velocity correlations tend to a stationary value in the long time limit. On the other hand, the scaled standard deviation of the total energy diverges, that is, the system shows multiscaling. Second, we find an exact solution for the velocity correlations in terms of the spectrum of eigenvalues of a certain matrix. The results of numerical simulations of the microscopic model confirm our theoretical results, including the above described multiscaling phenomenon.
