description: Strain in a material induces shifts in vibrational frequencies, which is a probe of the nature of the vibrations and interatomic potentials, and can be used to map local stress/strain distributions via Raman microscopy. This method is standard for crystalline silicon devices, but due to lack of calibration relations, it has not been applied to amorphous materials such as hydrogenated amorphous silicon (a-Si:H), a widely studied material for thin-film photovoltaic and electronic devices. We calculated the Raman spectrum of a-Si:H \ab initio under different strains $ε$ and found peak shifts $Δω= \left( -460 \pm 10\ \mathrm{cm}^{-1} \right) {\rm Tr}\ ε$. This proportionality to the trace of the strain is the general form for isotropic amorphous vibrational modes, as we show by symmetry analysis and explicit computation. We also performed Raman measurements under strain and found a consistent coefficient of $-510 \pm 120\ \mathrm{cm}^{-1}$. These results demonstrate that a reliable calibration for the Raman/strain relation can be achieved even for the broad peaks of an amorphous material, with similar accuracy and precision as for crystalline materials.

description: Prediction of low-mass $W_R$ and $Z_R$ gauge bosons in popular grand unified theories has been the subject of considerable attention over the last three decades. In this work we show that when gravity induced corrections due to dim.5 operator are included the minimal symmetry breaking chain of $SO(10)$ and $E_6$ GUTs can yield $W_R^{\pm}$ and $Z_R$ bosons with masses in the range $(3-10)$ TeV which are accessible to experimental tests at the Large Hordan Collider. The RH neutrinos turn out to be heavy pseudo-Dirac fermions. The model can fit all fermion masses and manifest in rich structure of lepton flavor violation while proton life time is predicted to be much longer than the accessible limit of Super-Kamiokande or planned Hyper-Kamiokande collaborations.

description: We report an accurate study of interactions between Benzene molecules using variational quantum Monte Carlo (VMC) and diffusion quantum Monte Carlo (DMC) methods. We compare these results with density functional theory (DFT) using different van der Waals (vdW) functionals. In our QMC calculations, we use accurate correlated trial wave functions including three-body Jastrow factors, and backflow transformations. We consider two benzene molecules in the parallel displaced (PD) geometry, and find that by highly optimizing the wave function and introducing more dynamical correlation into the wave function, we compute the weak chemical binding energy between aromatic rings accurately. We find optimal VMC and DMC binding energies of -2.3(4) and -2.7(3) kcal/mol, respectively. The best estimate of the CCSD(T)/CBS limit is -2.65(2) kcal/mol [E. Miliordos et al, J. Phys. Chem. A 118, 7568 (2014)]. Our results indicate that QMC methods give chemical accuracy for weakly bound van der Waals molecular interactions, comparable to results from the best quantum chemistry methods.

Investigating novel mechanisms of Translesion Synthesis (TLS) regulation in cancer
Creators: name: Holk, Alicia
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Cells are subjected to a range of DNA damaging agents from intrinsic, environmental, and therapeutic sources. The ability to cope with DNA damage is essential for maintaining genomic stability and preventing disease. Trans-lesion Synthesis(TLS) is a mechanism by which cells tolerate DNA damage by utilizing flexible, albeit error-prone, polymerases to bypass DNA lesions. Here we show that aberrantly expressed cancer testes antigen, Melanoma-Associated Antigen 4 (MAGE-A4), is a unique regulator of TLS in many neoplastic cells, demonstrating a novel mechanism for both mutagenesis and therapy-resistant cancer. Owing to its role in chemoresistance, TLS represents an appealing pathway for targeted cancer therapies. As an initial step in the drug discovery process we have identified small molecule inhibitors which target the essential interaction between TLS Polymerase Eta and mono-ubiquitinated PCNA. Taken together, we have identified a new mechanism for conferring tumorigenic phenotypes and initiated efforts to target this pathway for therapeutic purposes.
title: A study of coupled dielectric waveguides and their application to millimetre-wave components
Creators: name: Young, P. R.
Publisher: name: University of Kent
Year: 2023

description: This thesis studies the propagation characteristics of coupled dielectric waveguides and their application to millimetre-wave components. Firstly, by applying the transverse boundary conditions, exact characteristic equations for single and coupled dielectric slab waveguides are obtained. By assuming that the loss tangent of the guiding and surrounding region is small, approximate expressions for the attenuation constant are then derived. These expressions relate the attenuation constant directly to the lossless propagation constant and the waveguide parameters; their evaluation is then straightforward. Secondly, by defining an effective loss tangent, the slab guide solutions are used in the effective dielectric constant (EDC) method and the dual effective-index method (DEIM) to yield a simple, yet accurate method for the evaluation of the complex propagation constant of single and coupled dielectric waveguides with rectangular cross-sections. Furthermore, it is shown that the presented results are in good agreement with both finite element values and experimental data obtained using the open resonant cavity technique. By considering transitions between single and coupled dielectric slab guides, and the resulting coupling effects, several dielectric waveguide components are described. Each device relies on a short length of coupled waveguide formed by placing a movable block of dielectric parallel to a dielectric guide. It is shown that if the block is of the same material, and has identical cross-sectional dimensions to the waveguide, the effects of coupling can be exploited to achieve a variable attenuation. It is further shown that the separation at which maximum attenuation arises is dependent on the operating frequency; the structure can therefore be used as a wavemeter. By introducing large asymmetries into the device, the effects of coupling are prevented. Tinder these conditions, the device operates as a low-loss phase- shifter.

description: First Nations women who live on reserves receive maternity care from a variety of government health care systems: Federal, provincial, and municipal. At first glance, this seems like an abundant amount of health care; however, the lack of coordination has led to poorer outcomes as demonstrated for example by the twofold IMR for First Nations on reserves compared to that of non-Aboriginal populations. To inform discussions and changes to health care policy and programming for maternity care for First Nations on reserves, my dissertation focuses on Health Canada’s evacuation policy within the province of Manitoba. It describes how First Nations women journey among these three health care systems in the provision of that care. This federal policy instructs federally employed nurses to arrange for the transfer of pregnant First Nations women who live on rural and remote reserves to an urban – and usually southern – location so that the women can receive labour and birthing services. Women are evacuated out of their home communities between 36 and 38 weeks gestational age and wait in the city, often alone, for labour to start. While there is a general understanding of how different elements of this federal policy work, there is no literature that describes its execution in detail nor in full. To address this critical knowledge gap, my dissertation consists of three stand-alone papers. For the first paper, “‘This Policy Sucks and It’s Stupid:’ Mapping Maternity Care for First Nations Women on Reserves in Manitoba,” I used intersectionality, institutional ethnography, and semi-structured interviews to produce a descriptive and visual map of the evacuation policy. Using intersectionality and a case study approach, the second paper, “Health Canada’s Evacuation Policy for Pregnant First Nations Women in Manitoba: Resignation, Resilience, and Resistance,” semi-structured interview data are analyzed through a thematic analysis to understand the experiences and perspectives of First Nations women, family, and community members. I argue for the development of a specific theoretical framework that makes explicit the specific legal and policy influences particular to First Nations women who live on reserves in the third paper, “The Legal Categorization of First Nations Women in Health: The Need for a First Nations Feminist Theory.” Taken as a whole, these three papers address some of the knowledge gaps related to maternity care services for First Nations women once they are evacuated. They also situate these gaps within the legal context of health care for First Nations women so that tangible improvements can be made.
Transnationalism and performance: Mexican Astrid Hadad, Chicana Mónica Palacios, and strategies of the oppressed
Creators: name: Godoy Navarro, Zaida
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: The strong national emphasis contained in the works of Mexican Astrid Hadad and Chicana Mónica Palacios should distance them, since they come from different countries. Rather than that, the term "transnationalism" explains the similarities that will be analyzed between both contemporary women. The Mexico/US national borders crossed by means of "transnationalism" represent just one of the limitations that these women confront for not belonging to the "dominant" culture of their societies. The very genre that they work with, theater, is challenged by the relevance given to the elements added: dance, music, singing, visual elements and, in the case of Palacios, stand-up comedy. Both Hadad and Palacios have often been categorized as performance women because of this and the central role that their bodies achieve during their shows. This study links them first by focusing on the several historical traditions that have influenced them (diachronically) and, then, by analyzing the similar strategies with which they address oppression and create art (synchronically).

description: The aim of the study was to determine the level of support for innovation in agriculture and rural areas by RDP 2014-2020 on the example of the measure “Cooperation” (M16). Data from the Agency for Restructuring and Modernization of Agriculture (2021) were used. Based on the analysis of all projects implemented in Poland, the size of the allocation of funds was determined broken down into subsequent calls. The spatial differentiation at the regional and local level was indicated, and detailed directions of spending the funds were specified. In total, 334 projects were submitted in the 3 analyzed calls for proposals, of which 48.2% received financial support. The total amount of co-financing was PLN 448.19 million. The allocation of funds was spatially uneven, which is visible both at the regional and local levels. Taking into account the place of implementation of projects, the greatest amount of aid was spent in the Mazowieckie, Łódzkie and Kujawsko-Pomorskie voivodeships. In north-eastern and north-western Poland, most poviats did not support the development of innovation in agriculture and rural areas under measure M16. Most projects implemented under RDP 2014-2020 concerned poultry and cattle, then apples, pigs, herbs, beekeeping, hemp, support for supply chains, cereals and potatoes. Projects supporting the development of technological innovations dominated.

description: We propose a radiative seesaw model in alternative left-right model without any bidoublet scalar fields, in which all the fermion masses in the standard model are generated through a canonical seesaw mechanism at the tree level. On the other hand the observed neutrino masses are generated at two-loop level. In this paper we focus on the neutrino sector and show how to induce the active neutrino masses. Then we discuss the observed neutrino oscillation, constraints from lepton flavor violations, new sources of muon anomalous magnetic moment, a long-lived dark matter candidate with keV scale mass, and collider physics.

When the one who bears the scars is the one who strikes the blow: history, human rights, and Haiti's restavèks
Creators: name: Wagner, Laura Rose
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: The practice of keeping restavèks, or unpaid domestic child laborers, in Haiti has come under scrutiny by both human rights activists and journalists, many of whom describe it as a form of slavery. While this description is not entirely inaccurate and may also be useful, it fails to reflect the variability of treatment of restavèks, the complex ways in which power is exercised, the ways in which people occupy "oppressor" and "oppressed" roles simultaneously, the various local understandings of restavèk relationships and human rights, and the particular historical meanings and memories attached to slavery in Haiti. By critically examining descriptions of restavèks in activist and journalistic discourse, and analyzing the data collected during my fieldwork in the Haitian community in South Florida, I point to more syncretic and inclusive ways of understanding and reforming the practice of keeping restavèks.

description: We exploit the first public data release of VIPERS to investigate environmental effects in galaxy evolution between $z\sim0.5$ and $0.9$. The large number of spectroscopic redshifts over an area of about $10\,\mathrm{deg}^2$ provides a galaxy sample with high statistical power. The accurate redshift measurements, with $σ_z = 0.00047(1+z_\mathrm{spec})$, allow us to robustly isolate galaxies living in the lowest- and highest-density environments, as defined in terms of spatial 3D density contrast. We estimate the stellar mass function (SMF) of galaxies residing in these two environments, and constrain its high-mass end with unprecedented precision. We find that the galaxy SMF in the densest regions has a different shape than that measured at low densities, with an enhancement of massive galaxies and a hint of a flatter (less negative) slope at $z<0.8$. We normalise each SMF to the comoving volume occupied by the corresponding environment, and relate estimates from different redshift bins. We observe an evolution of the SMF of VIPERS galaxies in high densities, while the low-density one is nearly constant. We compare these results to semi-analytical models and find consistent environmental signatures. We discuss how the halo mass function and fraction of central/satellite galaxies depend on the environments considered, making intrinsic and environmental properties of galaxies physically coupled, and therefore difficult to disentangle. The evolution of our low-density regions is well described by the formalism introduced by Peng et al.~(2010), and is consistent with the idea that galaxies become progressively passive because of internal physical processes. The same formalism could also describe the evolution of the SMF in the high density regions, but only if a significant contribution from dry mergers is considered. [Abridged]

Home Instruction for the Parents of Preschool Youngsters (HIPPY)

description: This qualitative research project reconceptualizes conventional and prescriptive views of family literacy as literacies in the context of family relationships, experimenting with data from the home visitor participants of one international family literacy intervention program (FLIP): Home Instruction for the Parents of Preschool Youngsters (HIPPY). Participants of the HIPPY program in Canada primarily include newcomer families. While the program targets conventional forms of literacy and education relating to children’s school readiness, in practice their work with these families goes far beyond this initial focus further engaging with issues related to settlement. For example, after completing HIPPY’s two-year program successfully with their own children, parents can be hired to become home visitors, receive professional development and guide newcomer families through the HIPPY materials they will use with their children. Using the theoretical and practical lens of Multiple Literacy Theory (Masny, 2006, 2009, 2013) this project asks what literacy practices home visitors engage in with newcomer parents, how these practices function in the relationship, and what these practices produce in these interactions. Lombard (1981) recognized the need for further research on home visitor experiences after program coordinators noted the “highly visible changes in home visitors’ level of understanding and performance” (p. 89). Since then, however, parents and children continued to be the main focus of research. This project seeks to to illuminate the under-researched experiences of HIPPY home visitors. Using the theoretical and practical lens of Multiple Literacy Theory (Masny, 2006, 2009, 2013) and the philosophy of Deleuze and Guattari (1987), qualitative observation and interview data were collected and analyzed through the process of rhizoanalysis, creating four mappings. The first mapping experiments with HIPPY not as an isolated program, but as part of a much larger assemblage of programs and services focused on newcomers in a Canadian community. The second mapping looks closely at HIPPY and English language acquisition. Mapping three experiments with conceptualizations of HIPPY home visitors as instructors of “Canadian culture”, and the fourth and final mapping delves into a more specific cultural focus on home and school connections. The final chapter of the dissertation is not a conclusion, but a look forward. This chapter introduces the concept of literacies in the context of family relationships as an integral part of not only early learning, but public and community health.

description: We study the nonlocality of arbitrary dimensional bipartite quantum states. By computing the maximal violation of a set of multi-setting Bell inequalities, an analytical and computable lower bound has been derived for general two-qubit states. This bound gives the necessary condition that a two-qubit state admits no local hidden variable models. The lower bound is shown to be better than that from the CHSH inequality in judging the nonlocality of some quantum states. The results are generalized to the case of high dimensional quantum states, and a sufficient condition for detecting the non-locality has been presented.

Chemical Characterization and Reactive Oxidant Potential of Indonesian Biomass Burning Emissions
Creators: name: Williams, Michael
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Atmospheric fine particulate matter (PM2.5) has adverse impacts on air quality, climate, and human health. Primary emissions from biomass burning (BB) in Indonesia can substantially contribute to PM2.5 concentrations; however, its chemical composition remains unresolved. In this study, we examined the chemical composition of PM2.5 primarily emitted from laboratory burns of Indonesian biomass fuels and ambient PM2.5 collected from Singapore when it was influenced by air masses originating from Indonesian peatland fires. We also applied the dithiothreitol (DTT) assay to assess if these samples have oxidative stress potential. We found that laboratory samples generated greater DTT activity compared to previous studies examining diesel particles. Ambient samples generated smaller DTT activity, suggesting that fresh BB-derived PM2.5 likely has greater oxidative stress potential than aged BB-derived PM2.5. Levoglucosan, an abundant chemical tracer of primary BB emissions, was not associated with DTT activity, suggesting that other primary BB constituents are more DTT active.

description: We study the problem of two interacting particles in a two-dimensional quasiperiodic potential of the Harper model. We consider an amplitude of the quasiperiodic potential such that in absence of interactions all eigenstates are exponentially localized while the two interacting particles are delocalized showing anomalous subdiffusive spreading over the lattice with the spreading exponent $b \approx 0.5$ instead of a usual diffusion with $b=1$. This spreading is stronger than in the case of a correlated disorder potential with a one particle localization length as for the quasiperiodic potential. At the same time we do not find signatures of ballistic FIKS pairs existing for two interacting particles in the one-dimensional Harper model.

Machine Learning Performance Prediction of an Ion Deposited Membrane Atmospheric Water Harvesting Unit

Publisher: name: University of Illinois at Chicago
Year: 2023

description: Water scarcity is certainly one of the most relevant and worrying issues of the 21st century, affecting billions of people and limiting their access to safe water. Atmospheric water harvesting technologies have been under research and development for decades now to relieve — and eventually overcome — water scarcity in affected areas. Such technologies have been drawing increasing attention in the last years, due to the possibility of employing renewable energy sources to power the main physical processes involved. This study analyzes the performance of a novel membrane based harvesting unit under various operating conditions and using multiple structural designs. The lab-scale prototype (featuring a single membrane of surface area 160 cm2, active contact area 123.5 cm2) yield was as high as 354 ml/day of water, with an average of 155 ml/day, corresponding to water harvesting rates of 22.13 kg/m2/day and 9.69 kg/m2/day, respectively. When designing a commercial scale plant, as well as during its operation, it is important to have an easy tool to predict the production of water from the system: in this sense, machine learning models represent a much more convenient solution than complex and computationally expensive physics-based models. This study compares the performance and stability of models created using four machine learning techniques. The techniques applied and discussed are Support Vector Regression, Gradient Boosting Regression, Multilayer Perceptron, and Generalized Regression Neural Networks, all of which are particularly efficient in describing non-linear relationships even when the data set and the number of features per sample are of moderate dimensions. The first three methods achieved noteworthy results, thus proving suitable for employment in the regulation of an atmospheric water harvesting plant featuring the analyzed technology.

description: The traditional technique of gastrointestinal reconstruction of the esophagus after esophagectomy presents plenty of complications. Hence, tissue engineering has been introduced as an effective artificial alternative with potentially fewer complications. Three types of esophageal scaffolds have been used in experimental studies so far. therefore, we performed a meta-analysis in order to present the postoperative outcomes after esophageal replacement with artificial scaffolds and the investigation of possible factors that affect these outcomes.

The existence of such states is enabled by the metal-like optical properties of the excitonic layer based on aggregated dye molecules. Experimentally determined dispersion curves, together with simulated data, including field profiles, allow us to identify the nature of these new modes. Our results demonstrate the potential of organic excitonic materials as a powerful means to control light at the nanoscale, offering the prospect of a new alternative type of nanophotonics based on molecular materials.

description: While the discovery of Dirac and Weyl type excitations in electronic systems is a major breakthrough in recent condensed matter physics, finding appropriate materials for fundamental physics and technological applications, is an experimental challenge. In all the reported materials, linear dispersion survives only up to a few hundred meV from the Dirac or Weyl nodes. On the other hand, real materials are subject to uncontrolled doping during preparation and thermal effect near room temperature can hinder the rich physics. In ZrSiS, ARPES measurements have shown an unusually robust linear dispersion (up to $\sim$2 eV) with multiple non-degenerate Dirac nodes. In this context, we present the magnetotransport study on ZrSiS crystal, which represents a large family of materials (\textit{WHM} with \textit{W} = Zr, Hf; \textit{H} = Si, Ge, Sn; \textit{M} = O, S, Se, Te) with identical band topology. Along with extremely large and non-saturating magnetoresistance (MR), $\sim$ 1.4 $\times$ 10$^{5}$ \% at 2 K and 9 T, it shows strong anisotropy depending on the direction of the magnetic field. Quantum oscillation and Hall effect measurements have revealed large hole and small electron Fermi pockets. Non-trivial $π$ Berry phase confirms the Dirac fermionic nature for both types of charge carriers. The long-sought relativistic phenomenon of massless Dirac fermions, known as Adler-Bell-Jackiw chiral anomaly, has also been observed.

description: Discrete element modelling (DEM) is one of the most efficient computational approaches to the fracture processes of heterogeneous materials on mesoscopic scales. From the dynamics of single crack propagation through the statistics of crack ensembles to the rapid fragmentation of materials DEM had a substantial contribution to our understanding over the past decades. Recently, the combination of DEM with other simulation techniques like Finite Element Modelling further extended the field of applicability. In this paper we briefly review the motivations and basic idea behind the DEM approach to cohesive particulate matter and then we give an overview of on-going developments and applications of the method focusing on two fields where recent success has been achieved. We discuss current challenges of this rapidly evolving field and outline possible future perspectives and debates.

description: In experimental benchmarks of the accelerator-driven system (ADS) conducted at the Kyoto University Critical Assembly (KUCA), the prompt neutron decay constant α was measured using two types of pulsed neutron sources, i.e. a D-T neutron source and a spallation neutron source driven by a 100-MeV proton beam. The measurement results of α are useful information to validate the numerical results predicted by the prompt ω-eigenvalue calculation. In this study, the numerical analysis of α using a multi-energy group SN neutron transport code was carried out for the uranium-lead zoned experimental cores. To reduce the discretization error owing to the deterministic code, the KUCA geometry was modelled in detail as a three-dimensional heterogeneous plate-by-plate geometry, and an improved variant of EON quadrature was utilized. In addition, the sensitivity coefficients of α with respect to nuclear data were efficiently evaluated by first-order perturbation theory, followed by nuclear data-induced uncertainty quantification based on the 56 neutron-energy group SCALE covariance library. Consequently, the numerical results of α were validated successfully by the experimental results of the pulsed neutron source method, compared with the range of the nuclear data-induced uncertainties.
A Fountain Bewitched: Gender, Sin, and Propaganda in the Massa Marittima Mural
Creators: name: Longenbach, Erica M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: The fountain mural discovered in 2000 in the Tuscan town of Massa Marittima has drawn international attention due to its rare iconographic allusions to fertility and witchcraft in late thirteenth century Italy. The mural, which depicts eight women underneath a deciduous tree with phalli hanging from its branches in lieu of fruit, raises numerous questions. In this thesis, I examine the positive classical iconographic associations to fertility and auspiciousness and how these symbols came to be reinterpreted within a Christian context as elements of sin and temptation. Furthermore, the connections between the lingering classical prototype of a woman as a being of unbridled sexuality, temptation, and bearer of prophetic knowledge continued to manifest themselves in medieval folklore beliefs of witchcraft and its artistic representations in the high and late Middle Ages. The mural is evidence of how these anxieties were effectively appropriated into the genre of propagandistic political art during a time of civil unrest in central Italy.

description: Metadislocations are novel defects recently identified in complex metallic alloys. It was reasoned that their propagation necessarily requires the orchestrated motion of hundreds of atoms along various crystallographic directions per elementary step. Here, we report on the direct observation of the motion of metadislocations on the atomic scale in the complex metallic alloy phase T-Al-Mn-Fe, using in-situ high-resolution transmission electron microscopy. We observe their propagation by discrete jumps between low-energy configurations. Using a tiling model, we determine their characteristic features including the Burgers vector, and identify their motion to take place in a mixed glide/climb process. We report on the direct in-situ observation of the motion of metadislocations in the transmission electron microscope, establishing a novel mechanism of plastic deformation in a structurally complex metallic alloy.
Stability of rotating magnetized jets in the solar atmosphere. I. Kelvin-Helmholtz instability

description: Observations show various jets in the solar atmosphere with significant rotational motions, which may undergo instabilities leading to heat ambient plasma. We study the Kelvin-Helmholtz (KH) instability of twisted and rotating jets caused by the velocity jumps near the jet surface. We derive a dispersion equation with appropriate boundary condition for total pressure (including centrifugal force of tube rotation), which governs the dynamics of incompressible jets. Then, we obtain analytical instability criteria of Kelvin-Helmholtz instability in various cases, which were verified by numerical solutions to the dispersion equation. We find that twisted and rotating jets are unstable to KH instability when the kinetic energy of rotation is more than the magnetic energy of the twist. Our analysis shows that the azimuthal magnetic field of 1-5 G can stabilize observed rotations in spicule/macrospicules and X-ray/EUV jets. On the other hand, non-twisted jets are always unstable to KH instability. In this case, the instability growth time is several seconds for spicule/macrospicules and few minutes (or less) for EUV/X-ray jets. We also find that standing kink and torsional Alfven waves are always unstable near the antinodes due to the jump of azimuthal velocity at the surface, while the propagating waves are generally stable. KH vortices may lead to enhanced turbulence development and heating of surrounding plasma, therefore rotating jets may provide energy for chromospheric and coronal heating.

description: In this paper, we study transport features of a one-dimensional beam-plasma system in the presence of multiple resonances. As a model description of the general problem of a warm energetic particle beam, we assume $n$ cold supra-thermal beams and investigate the self-consistent evolution in the presence of the complete spectrum of nearly degenerate Langmuir modes. A qualitative transport estimation is obtained by computing the Lagrangian Coherent Structures of the system on given temporal scales. This leads to the splitting of the phase space into regions where the local transport processes are relatively faster. The general theoretical framework is applied to the case of the nonlinear dynamics of two cold beams, for which numerical simulation results are illustrated and analyzed.
