description: We present improved measurements of the branching fraction and CP asymmetry for the process B+ --> rho+ pi0. The data sample corresponding to 211/fb comprises 232 million Y(4S)-->BBbar decays collected with the BABAR detector at the PEP-II asymmetric B Factory at SLAC. The yield and CP asymmetry are measured using an extended maximum likelihood fitting method. The branching fraction and CP asymmetry are found to be BR(B+ --> rho+ pi0)= [10.2 +- 1.4(stat) +- 0.9(syst)] x 10^-6 and Acp (B+ --> rho+ pi0) = -0.01 +- 0.13(stat) +- 0.02(syst).

Towards a wave-extraction method for numerical relativity. V. Extracting the Weyl scalars in the quasi-Kinnersley tetrad from spatial data

description: We extract the Weyl scalars $Ψ_0$ and $Ψ_4$ in the quasi-Kinnersley tetrad by finding initially the (gauge--, tetrad--, and background--independent) transverse quasi-Kinnersley frame. This step still leaves two undetermined degrees of freedom: the ratio $|Ψ_0|/|Ψ_4|$, and one of the phases (the product $|Ψ_0|\cdot |Ψ_4|$ and the {\em sum} of the phases are determined by the so-called BB radiation scalar). The residual symmetry ("spin/boost") can be removed by gauge fixing of spin coefficients in two steps: First, we break the boost symmetry by requiring that $ρ$ corresponds to a global constant mass parameter that equals the ADM mass (or, equivalently in perturbation theory, that $ρ$ or $μ$ equal their values in the no-radiation limits), thus determining the two moduli of the Weyl scalars $|Ψ_0|, |Ψ_4|$, while leaving their phases as yet undetermined. Second, we break the spin symmetry by requiring that the ratio $π/τ$ gives the expected polarization state for the gravitational waves, thus determining the phases. Our method of gauge fixing--specifically its second step--is appropriate for cases for which the Weyl curvature is purely electric. Applying this method to Misner and Brill--Lindquist data, we explicitly find the Weyl scalars $Ψ_0$ and $Ψ_4$ perturbatively in the quasi-Kinnersley tetrad.

description: We report measurements of resonant thermal capillary oscillations of a hemispherical liquid gas interface obtained using a half bubble deposited on a solid substrate. The thermal motion of the hemispherical interface is investigated using an atomic force microscope cantilever that probes the amplitude of vibrations of this interface versus frequency. The spectrum of such nanoscale thermal oscillations of the bubble surface presents several resonance peaks and reveals that the contact line of the hemispherical bubble is pinned on the substrate. The analysis of these peaks allows to measure the surface viscosity of the bubble interface. Minute amounts of impurities are responsible for altering the rheology of the pure water surface.

description: No abstracts are to be cited without prior reference to the author. The main contributor to the Celtic Sea herring (Clupea harengus) stock are winter spawning fish and a smaller proportion of autumn spawners. Spawning takes place from October to February. Celtic Sea (CS) herring is managed as one stock within the ICES areas VIIj, VIIg and VIIaS. Stock biomass crashed in the early 1980s and 2000s. A precautionary management plan was installed in 2004. Stock biomass showed a strong increase over the last five years. The Irish Celtic Sea region is on a shallow plateau, 80 -100m deep. Herring spawning grounds are characterised by gravel and a proximity to river outlets.

description: We study numerically the chromoelectric-chromomagnetic asymmetry of the dimension two $A^2$ gluon condensate as well as the infrared behavior of the gluon propagators at $T\simeq T_c$ in the Landau-gauge $SU(3)$ lattice gauge theory. We find that a very significant correlation of the real part of the Polyakov loop with the asymmetry as well as with the longitudinal propagator makes it possible to determine the critical behavior of these quantities. We obtain the screening masses in different Polyakov-loop sectors and discuss the dependence of chromoelectric and chromomagnetic interactions of static color charges and currents on the choice of the Polyakov-loop sector in the deconfinement phase.

description: Alternative splicing of pre-mRNA allows a single gene to produce different proteins in eukaryotes, and they have been shown to affect various gene functions, and eventually disease. Most widely used approaches to alternative splicing analysis using RNA-seq data are based on either predefined simple alternative splicing events (e.g., exon skipping) or full-length transcripts. While the transcript-based approach provides a global picture of splicing patterns along transcripts, it poses major challenges because 1) each RNA-seq read has information on only a small part of a transcript, and 2) alternative transcripts from the same gene often share a large amount of sequence. To overcome these challenges, we propose to build a probabilistic model as an approximation to the underlying splicing processes, rather than modeling individual outcomes of the processes such as exon skipping, individual transcripts, etc. Our model is based on gene-wide usage of splice sites. Specifically, we first assume that potential 5' and 3' splice sites are given. This information can be obtained from annotation databases or estimated from RNA-seq data by using other methods. Those potential splice sites partition a gene into a sequence of segments. We introduce a sequence of hidden variables, each of which indicates whether a corresponding segment is part of a transcript. We model the splicing process by assuming that this sequence of hidden variables follows an inhomogeneous Markov chain. The parameters in the model are interpreted as splice site usage. Using those parameters, we can describe the splicing process, and estimate the probabilities of various local splicing events.

description: Recent femtoscopic measurements involving the use of an imaging technique and a newly developed moment analysis are presented and discussed. We show that this new paradigm allows robust investigation of reaction dynamics for which the sound speed $c_s \neq 0$ during an extended hadronization period. Source functions extracted for charged pions produced in Au+Au and Pb+Pb collisions show non-Gaussian tails for a broad selection of collision energies. The ratio of the RMS radii of these source functions in the out and side directions are found to be greater than 1, suggesting a finite emission time for pions.

description: No abstracts are to be cited without prior reference to the author. The early life history stages of fish are considered the most vulnerable and can be strongly affected by environmental variability, leading to inter-annual population fluctuations. Temperature has a major role on development and mortality rates, with consequences for recruitment and overall stock productivity. We collated development and survival data from publications on laboratory egg incubation experiments to investigate and compare the development, daily mortality and survival of fish eggs from pelagic species in the north Atlantic, and to investigate whether trade-offs exist between these traits at the population and species level and between demersal and pelagic eggs. The functional response of each trait to a temperature increase was generally similar regardless of species. However, when comparing the magnitude of response, different adaptations were found among species/populations and egg type. At the egg type level, a trade-off probably exists between fast development and high mortality or slow development and low mortality, resulting in similar survival percentages. These results quantify physiological effects of temperature on the eggs. Future studies which combine these results with adult traits (e. g., fecundity) can be used to investigate the potential for different pelagic species to maintain or establish populations in the future warmer north Atlantic.
Towards a semiclassical justification of the `effective random matrix theory' for transport through ballistic chaotic quantum dots

description: The scattering matrix S of a ballistic chaotic cavity is the direct sum of a `classical' and a `quantum' part, which describe the scattering of channels with typical dwell time smaller and larger than the Ehrenfest time, respectively. According to the `effective random matrix theory' of Silvestrov, Goorden, and Beenakker [Phys. Rev. Lett. 90, 116801 (2003)], statistical averages involving the quantum-mechanical scattering matrix are given by random matrix theory. While this effective random matrix theory is known not to be applicable for quantum interference corrections to transport, which appear to subleading order in the number of scattering channels N, it is believed to correctly describe quantum transport to leading order in N. We here partially verify this belief, by comparing the predictions of the effective random matrix theory for the ensemble averages of polynomial functions of S and S^dagger of degree 2, 4, and 6 to a semiclassical calculation.

description: Glucose monitoring plays a critical role in managing diabetes, one of the most prevalent diseases globally. The development of fast-responsive, cost-effective, and biocompatible glucose sensors is essential for improving patient care. In this study, a comparative analysis is conducted between pristine and Co-doped hematite samples, synthesized via the hydrothermal method, to evaluate their structural, morphological, and optical properties. The glucose sensing performance of both samples is assessed using a fiber-optic evanescent wave (FOEW) setup. While the sensitivity remains comparable for both pristine and Co-doped hematite, a reduction in the Limit of Detection (LoD) is observed in the Co-doped sample, suggesting enhanced interactions with glucose molecules at the surface. To gain further insights into the glucose adsorption mechanisms, Density Functional Theory (DFT) calculations are performed, revealing key details regarding charge transfer, electronic delocalization, and glucose binding on the hematite surfaces. These findings highlight the potential of Co-doped hematite for advanced glucose sensing applications, offering a valuable synergy between experimental and theoretical approaches for further exploration in biosensing technologies.

description: No abstracts are to be cited without prior reference to the author. In this study, the variation of seasonal and inter-annual fat content of foraging capelin (Mallotus villosus) is described. To explore long-term changes in fat content of capelin, annual fat index was made 1975 to 2012. The index was used as a response variable to see which environmental factors are likely to affect fat content of capelin such as temperature, salinity, zooplankton, biomass and large scale oceanic/atmospheric features (e.g. NAO, Blocking index). The annual fat index was also used as a predictor variable to explore if fat content can effect capelin stock recruitment and mean weight. A regression linear model showed that the only enviromental factor significantly affecting capelin fat content was the NAO index, explaining 25.9% of observed variation. The linear model also showed that the annual fat index has significant relationship with both recruitment- and mean weight of the capelin stock.

description: This paper presents a new data-driven controller synthesis based on the Koopman operator and the extended $\mathcal{H}_2$ norm characterization of discrete-time linear systems. We model dynamical systems as polytope sets which are derived from multiple data-driven linear models obtained by the finite approximation of the Koopman operator and then used to design robust feedback controllers combined with the $\mathcal{H}_2$ norm characterization. The use of the $\mathcal{H}_2$ norm characterization is aimed to deal with the model uncertainty that arises due to the nature of the data-driven setting of the problem. The effectiveness of the proposed controller synthesis is investigated through numerical simulations.

description: Competing interactions and geometric frustration provide favourable conditions for exotic states of matter. Such competition often causes multiple phase transitions as a function of temperature and can lead to magnetic structures that break inversion symmetry, thereby inducing ferroelectricity [1-4]. Although this phenomenon is understood phenomenologically [3-4], it is of great interest to have a conceptually simpler system in which ferroelectricity appears coincident with a single magnetic phase transition. Here we report the first such direct transition from a paramagnetic and paraelectric phase to an incommensurate multiferroic in the triangular lattice antiferromagnet RbFe(MoO4)2 (RFMO). A magnetic field extinguishes the electric polarization when the symmetry of the magnetic order changes and ferroelectricity is only observed when the magnetic structure has chirality and breaks inversion symmetry. Multiferroic behaviour in RFMO provides a theoretically tractable example of ferroelectricity from competing spin interactions. A Landau expansion of symmetry-allowed terms in the free energy demonstrates that the chiral magnetic order of the triangular lattice antiferromagnet gives rise to a pseudoelectric field, whose temperature dependence agrees with that observed experimentally.

description: The present work describes the synthesis, isolation and identification of six triorganotin compounds with amino substituted heterocyclic thioamides, namely 4-amino and 4,6-diamino-pyrimidine-2-thione.The compounds were studied by a variety of spectroscopic methods which include infrared, ultraviolet-visible, Mössbauer, nuclear magnetic resonance and X-ray diffraction. The structure of the compounds proved to consist of tetrahedral tin centres to which the thioamides are mono-coordianted through the exocyclic sulfur atom while in the solid state there exist extended networks due to the formation of hydrogen bonds between the amino- groups and the pyridine nitrogen atoms. The visible spectra lines were analysed with the aid of relevant software to Gaussian-type constituents and the nature of the excitations verified by means of semiemprical quantum-chemical calculations.The cytostatic activity of the tributyl derivatives was examined against MDA-MB-231 cells with the crystal violet technique. This preliminary study revealed a significant in vitro activity which is due probably to the release within the cell of both the well known toxic SnBu3+ unit and the very reactive thiol.

description: No abstracts are to be cited without prior reference to the author. Although the Atlantic salmon is primarily a fresh water fish it spends a big part of its adult life at sea as a fast moving pelagic predator. During this part of their life-cycle Atlantic salmon swim alongside and share the same ocean environments of commercially-fished species of the pelagic complex such as herring, mackerel and blue whiting. Atlantic salmon is now threatened by problems it’s facing during this ocean migration and international research is becoming more and more focused towards this phase of the salmon life-history profile. Here we present results of genetic assignment and otoliths and scale aging of marine caught salmon in Icelandic waters

description: No abstracts are to be cited without prior reference to the author. Acoustic telemetry has revealed new information on the behavior and migration of fish and invertebrate species, and telemetry is a powerful tool for stock identification. Case studies have demonstrated that telemetry can be used to investigate topics that are central to stock identification, such as homing, contingent structure, group movement patterns, and habitat preference (Bain, 2005; Heupel et al., 2006). Although telemetry has not been widely used for stock identification purposes to date, we expect that it will play a more prominent role in the future, because scientists and managers are increasingly seeking to identify and manage stock on a finer scale. As advancements in telemetry continue, this technology has the capacity to refine the spatial scale at which we identify and manage fish stocks. To achieve the most holistic and accurate results, telemetry should be coupled with other stock identification techniques such as genetics, otolith microchemistry, and analysis of life history traits

description: Wireless sensor networks (WSNs) have emerged as one of the most promising technologies for the current era. Researchers have studied them for several years ago, but more work still needed to be made since open opportunities to integrate new technologies are added to this field. One challenging task is WSN deployment. Yet, this is done by real deployment with testbeds platforms or by simulation tools when real deployment could be costly and time-consuming. In this paper, we review the implementation and evaluation process in WSNs. We then describe relevant testbeds and simulation tools, and their features. Lastly, we conduct an experimentation study using these testbeds and simulations to highlight their pro and cons. As a use case, we implement a localization protocol. This work gives clarity to future-work for better implementation in order to improve reliability, accuracy and time consumed.

description: We have investigated the prototype kaonic nucleus, $ppK^-$, using the method of Antisymmetrized Molecular Dynamics (AMD). In the present study we use a realistic $NN$ potential with strongly repulsive core, and a Chiral SU(3)-based $\bar{K}N$ interaction which is energy-dependent and includes both $s$- and p-wave interactions. We find that no self-consistent solutions exist when the range parameter of the $\bar{K}N$ interaction is less than 0.67 fm. Due to the strong repulsion of the $NN$ interaction at short distance, the two nucleons in $ppK^-$ keep a distance of about 1.2 fm and the total binding energy of $ppK^-$ does not exceed about 50 MeV in the scope of our current analysis.

description: We investigate the maximal violations for both sides of the $d$-dimensional CGLMP inequality by using the Bell operator method. It turns out that the maximal violations have a decelerating increase as the dimension increases and tend to a finite value at infinity. The numerical values are given out up to $d=10^6$ for positively maximal violations and $d=2\times 10^5$ for negatively maximal violations. Counterintuitively, the negatively maximal violations tend to be a little stronger than the positively maximal violations. Further we show the states corresponding to these maximal violations and compare them with the maximally entangled states by utilizing entangled degree defined by von Neumann entropy. It shows that their entangled degree tends to some nonmaximal value as the dimension increases.

description: No abstracts are to be cited without prior reference to the author. An proper estimate of tagging mortality is central to the accuracy of the results of many scientific projects involving electronic tagging of fishes. As part of the Ocean Tracking Network we used coded acoustic tags to derive a post release minimum survival estimate for Atlantic sturgeon (Acipenser oxyrinchus) captured by otter trawl in the Minas Basin, Bay of Fundy, Canada (minimum survival estimate = 97%). The Minas Channel leading to the Minas Basin is an area of interest for the production of in-stream tidal power, and supported a tidal power turbine in 2009. Future deployments of turbines are scheduled for 2016. We acoustically tagged 115 Atlantic sturgeon in the Minas Basin who subsequently passed through the Minas Channel. We gathered baseline information on tagging survival, depth preferences and seasonality critical for the mitigation of negative impacts of turbine operation on sturgeon and for the development of experimental design for future studies on fish turbine interactions.

We simplify the calculation of peculiar velocities of galaxy clusters using deep learning frameworks trained on numerical simulations to avoid the estimation of the optical depth. The image of distorted photon backgrounds are generated for idealized observations using one of the largest cosmological hydrodynamical simulations, the Magneticum simulations. The model is tested to be capable peculiar velocities from future kinetic SZ observations under different noise conditions. The deep learning algorithm displays robustness in estimating peculiar velocities from kinetic SZ effect by an improvement in accuracy of about 17% compared to the analytical approach.

description: In this work we propose the Z -> gamma gamma decay as a process strictly forbidden in the standard model, suitable for the search of noncommutativity of coordinates at very short distances. We computed the Z -> gamma gamma partial width in the framework of the recently proposed one-loop renormalizable gauge sector of the noncommutative standard model. New experimental possibilities at LHC are analyzed and a firm bound to the scale of noncommutativity parameter is set around 1 TeV.

description: Spin fluctuations have been proposed as a key mechanism for mediating superconductivity, particularly in high-temperature superconducting cuprates, where conventional electron-phonon interactions alone cannot account for the observed critical temperatures. Traditionally, their role has been analyzed through tight-binding based model Hamiltonians. In this work we present a method that combines density functional theory with a momentum- and frequency-dependent pairing interaction derived from the Fluctuation Exchange (FLEX) type Random Phase Approximation (FLEX-RPA) to compute Eliashberg spectral functions $α^{2}F(ω)$ which are central to spin fluctuation theory of superconductivity. We apply our numerical procedure to study a series of cuprates where our extracted material specific $α^{2}F(ω)$ are found to exhibit remarkable similarities characterized by a sharp peak in the vicinity of 40-60 meV and their rapid decay at higher frequencies. Our exact diagonalization of a linearized BCS gap equation extracts superconducting energy gap functions for realistic Fermi surfaces of the cuprates and predicts their symmetry to be $d_{x^{2}-y^{2}}$ in all studied systems. Via a variation of on-site Coulomb repulsion $U$ for the copper $d$-electrons we show that that the range of the experimental values of $T_{c}$ can be reproduced in this approach but is extremely sensitive to the proximity of the spin density wave instability. These data highlight challenges in building first-principle theories of high temperature superconductivity but offer new insights beyond previous treatments, such as the confirmation of the usability of approximate BCS-like $T_{c}$ equations, together with the evaluations of the material specific coupling constant $λ$ without reliance on tight-binding approximations of their electronic structures.

description: The Chandra X-ray Observatory, one of NASA's Great Observatories, has an outstanding record of scientific and technical success. This success results from the efforts of a team comprising NASA, its contractors, the Smithsonian Astrophysical Observatory, the instrument groups, and other elements of the scientific community -- including the thousands of scientists who utilize this powerful facility for astrophysical research. We discuss the role of NASA Project Science in the formulation, development, calibration, and operation of the Chandra X-ray Observatory. In addition to serving as an interface between the scientific community and the Project, Project Science performed what we term "science systems engineering". This activity encompasses translation of science requirements into technical requirements and assessment of the scientific impact of programmatic and technical trades. We briefly describe several examples of science systems engineering conducted by Chandra Project Science.

description: We investigate inverse proximity effects in a spin-triplet superconductor (TSC) interfaced with a ferromagnet (FM), assuming different types of magnetic profiles and chiral or helical pairings. The region of the coexistence of spin-triplet superconductivity and magnetism is significantly influenced by the orientation and spatial extension of the magnetization with respect to the spin configuration of the Cooper pairs, resulting into clearcut anisotropy signatures. A characteristic mark of the inverse proximity effect arises in the induced spin-polarization at the TSC interface. This is unexpectedly stronger when the magnetic proximity is weaker, thus unveiling immediate detection signatures for spin-triplet pairs. We show that an anomalous magnetic proximity can occur at the interface between the itinerant ferromagnet, SrRuO$_3$, and the unconventional superconductor Sr$_2$RuO$_4$. Such scenario indicates the potential to design characteristic inverse proximity effects in experimentally available SrRuO$_3$-Sr$_2$RuO$_4$ heterostructures and to assess the occurrence of spin-triplet pairs in the highly debated superconducting phase of Sr$_2$RuO$_4$.

description: In this paper we give an introduction to the numerical density matrix renormalization group (DMRG) algorithm, from the perspective of the more general matrix product state (MPS) formulation. We cover in detail the differences between the original DMRG formulation and the MPS approach, demonstrating the additional flexibility that arises from constructing both the wavefunction and the Hamiltonian in MPS form. We also show how to make use of global symmetries, for both the Abelian and non-Abelian cases.

subject: Education policy

description: United Kingdom Foreign Commonwealth & Development Office in Nigeria requested a literature review to gather evidence-based best practices and explore potential avenues for coordination and collaboration with other development partners to address improving safety and community resilience in and around schools and reintegration of kidnap victims. The request encompasses four key questions:1. What evidence exists – from Nigeria and elsewhere – about the needs of former abductees (e.g. psychosocial support, social and emotional learning) and the barriers preventing their successful reintegration into school and their communities?2. What is being done and by whom to increase school safety and community resilience to attacks in Nigeria?*3. What is being done and by whom to facilitate the reintegration of former abductees into communities and education systems in Nigeria?*4. What evidence exists – from Nigeria and elsewhere – about the effectiveness of existing approaches? What examples are there of alternative approaches that could be adapted to the context of Nigeria/affected states?
*Responses to questions 1 and 2 include: (i) national/state level policies; (ii) state and NGOs implemented programmes/initiatives; (iii) community-level initiatives, and (iv) systems for coordinating these efforts.

description: Σκοπός της παρούσας διπλωματικής εργασίας, η οποία εκπονήθηκε στα πλαίσια του προγράμματος μεταπτυχιακών σπουδών του κλάδου Εμπορικού και Οικονομικού Δικαίου του τμήματος Νομικής Α.Π.Θ., ήταν να μελετηθεί η ασφάλιση της περιβαλλοντικής ευθύνης, έννοια η οποία εισήχθη στο δίκαιό μας με το προεδρικό διάταγμα 148/2009, κατ’ επιταγή της Οδηγίας 2004/35/ΕΚ. Προκειμένου να γίνουν κατανοητές οι παραπάνω έννοιες, εξετάσθηκαν κατά πρώτον η έννοια του περιβάλλοντος καθώς και ορισμένα ζητήματα του δικαίου περιβάλλοντος γενικότερα. Στη συνέχεια μελετήσαμε τις σημαντικότερες διατάξεις που γεννούν αστική περιβαλλοντική ευθύνη, ώστε να φανεί εναργέστερα η διαφοροποίησή της από την δημοσίου δικαίου περιβαλλοντική ευθύνη. Περαιτέρω, αφού παρουσιάστηκε αδρομερώς το περιεχόμενο της Οδηγίας, εξετάστηκε η έννοια της περιβαλλοντικής ευθύνης, προκειμένου να προσεγγίσουμε την ασφάλιση της τελευταίας. Εν όψει της έλλειψης σχετικών λεπτομερειακών νομοθετικών ρυθμίσεων κατεβλήθη προσπάθεια αφενός να εξετάσουμε εάν η κλασική ασφάλιση αστικής περιβαλλοντικής ευθύνης μπορεί να συμπεριλάβει και τη νέα αυτή μορφή και αφετέρου να περιγράψουμε τις ιδιαιτερότητες και την εν γένει λειτουργία της ασφάλισης αυτής στην πράξη.
description: The aim of the present thesis, which was carried out during the postgraduate studies program of the department of Commercial and Economic Law of the Faculty of Law of the Aristotle University of Thessaloniki, was to study the environmental liability insurance, whose concept has been introduced in Greek legal system through presidential decree nr. 148/2009, which adopted the Directive 2004/35/EC. In order to understand the above mentioned concepts, we firstly examined the concept of the environment, as well as some legal issues of the environmental law in general. We afterwards examined the most important provisions regarding civil environmental liability, so as for its difference to the public environmental liability to become more apparent. Moreover, after briefly presenting the Directive’s provisions, we examined the concept of environmental liability, in order to approach its insurance. Due to the lack of detailed legal provisions, on the one hand we tried to figure out whether this new kind of insurance could be included in the classic civil environmental liability insurance, while on the other hand we tried to describe the specificities and the practical function in general of this kind of insurance.

description: No abstracts are to be cited without prior reference to the author. Animals form groups for many reasons but there are costs and benefit associated with group formation. One of the benefits is collective memory. In groups on the move, social interactions play a crucial role in the cohesion and the ability to make consensus decisions. When migrating from spawning to feeding areas fish schools need to retain a collective memory of the destination site over thousand of kilometers and changes in group formation or individual preference can produce sudden changes in migration pathways.

description: Employing dynamical cluster quantum Monte Carlo calculations we show that the single particle spectral weight A(k,w) of the one-band two-dimensional Hubbard model displays a high energy kink in the quasiparticle dispersion followed by a steep dispersion of a broad peak similar to recent ARPES results reported for the cuprates. Based on the agreement between the Monte Carlo results and a simple calculation which couples the quasiparticle to spin fluctuations, we conclude that the kink and the broad spectral feature in the Hubbard model spectra is due to scattering with damped high energy spin fluctuations.
