description: La production y consumo de la yautia coco (C. esculenta) aumentô un 35% en los ùltimos meses del 2003, luego que decenas de productores de arroz decidieran cambiar de cultivo para dedicarse a la siembra de este rubro. En el verano de 2004, se presentaron brotes epidémicos severos de una enfermedad en numerosas plantaciones de la parte nororiental del pais, lo que motivô a realizar muestreos con fines de diagnôstico. Las muestras fueron analizadas en los laboratorios de protection vegetal del IDIAF, en donde se aislô en PDA el hongo P. colocasiae. El diagnôstico obtenido confirma la presencia en Repûblica Dominicana de dicho hongo. La presencia del patôgeno en nuestro pais habia sido reportada por Holliday (1980) y Ciferri (1954). A pesar de que no han sido cuantificadas las pérdidas econômicas causadas por la enfermedad, los danos son considerables( ha afectado mâs del 50% del ârea sembrada en todo el pais), e inciden negativamente en la production y productividad del cultivo.

description: Research conducted on the bacterial spot disease caused by Xanthomonas campestris pv. vesicatoria on tomato, bell pepper and hot pepper in Barbados assessed prospects for genetic and chemical control of the disease on the island. Race and chemical resistance profiles of the pathogen, effectiveness of deployment of bacterial spot resistance genes in the field and the genetic basis for pathogen population changes with respect to pathogenicity and sensitivity to copper bactericides were examined. Twenty-four races of X. campestris pv. vesicatoria, 20 of which were previously unreported on bell pepper and tomato in Barbados, were identified. Race specific host selection, mutation and exchange of genetic material are postulated to explain the evolution of the pathogen population in Barbados. The research also reported the disease on hot pepper for the first time, with the most abundant bacterial races isolated being capable of overcoming resistance conferred by most available bacterial spot resistance genes in bell pepper. Chemical resistance profiles of isolates of X. campestris pv .vesicatoria indicated that 18.3 and 78.1 percent of the population were resistant to copper and zinc, respectively. Differentially resistant bell pepper and tomato were shown to succumb to the disease at significantly lower frequencies than susceptible cultivars grown alongside them. Copper resistance of X. campestris pv. vesicatoria was generally associated with the presence of a 0.6-0.9 kb plasmid which was transferable between strains. Reversion from copper resistance to sensitivity occurred at high frequencies in the absence of copper. The successful management of bacterial spot will require a multi-faceted approach including deployment of mixtures of resistance genes and exploitation of the bactericide resistance status of individual pepper and tomato fields.

description: Phase-change materials (PCMs), which are well-established in optical and random-access memories, are increasingly studied for emerging topics such as brain-inspired computing and active photonics. These applications take advantage of the pronounced reflectivity and resistivity changes that accompany the structural transition in PCMs from their amorphous to crystalline state. However, PCMs are typically fabricated as thin films via sputtering, which is costly, requires advanced equipment, and limits the sample and device design. Here, we investigate a simpler and more flexi-ble approach for applications in tunable photonics: the use of sub-10 nm colloidal PCM nanoparticles (NPs). We report the optical properties of amorphous and crystalline germanium telluride (GeTe) NP thin films from the infrared to the ultraviolet spectral range. Using spectroscopic ellipsometry with support from cross-sectional scanning electron microscopy, atomic force microscopy, and absorption spectroscopy, we extract refractive indices n, extinction coefficients k, and band gaps Eg and compare to values known for sputtered GeTe thin films. We find a decrease of n and k and an increase of Eg for NP-based GeTe films, yielding insights into size-dependent property changes for nanoscale PCMs. Furthermore, our results reveal the suitability of GeTe NPs for tunable photonics in the near-infrared and visible spectral range. Finally, we studied sample reproducibility and aging of our NP films. We found that the colloidally-prepared PCM thin films were stable for at least two months stored under nitrogen, further supporting the great promise of these materials in applications.

description: In about thirty years Martinique saw its agricultural surface decreasing. A great part of these surfaces have been absorbed by urbanization. However to safeguard the arable lands and the environment, while holding account of requirements in urbanization, a broad dialogue was started with all the actors of the regional planning To meet this need, it was agreed to make communal studies of sustainable agriculture in partnership with the local actors. A engineering and design department made up of Agriculture Chamber, CNASEA and SAFER was setup so: - to identify the parts of the territory having an important potential for agriculture - to propose rules of management adapted to each one these zones to ensure in a durable way the conservation of their agricultural destination In the second time a specific device of accompaniment of the farmers will be set up.

description: In this paper, we study a particular modified gravity Equation of State, the so-called Jaime-Jaber-Escamilla, that emerges from the first gravity modified action principle and can reproduce three cosmological viable $f(R)$ theories: the Starobinsky, Hu-Sawicki, and Exponential models . This EoS is a suitable candidate to reproduce the dynamical dark energy behaviour already reconstructed by the current data sets. Based on the joint statistical analysis, we found that our results are still in good agreement (within $1σ$) with the $Λ$CDM, while at perturbative level we notice that the matter power spectrum normalisation factor $σ_8$ shows an agreement with SDSS and SNeIa+IRAS at 1-$σ$ for the Starobinsky model and with SDSS-vec for the Hu \& Sawicki and Exponential models. Furthermore, we found that for the $H_0$ values, Starobinsky and Hu \& Sawicki show the least tension in comparison with PL18 TT. All these aspects cannot be observed \textit{directly} from other alternatives theories, were a equation of state is difficult to compute analytically.

description: Using our interferometric observations of seven classical Cepheids reported in Kervella et al. (2003, Paper I), complemented by previously existing measurements, we derive new calibrations of the Cepheids Period-Radius (P-R) and Period-Luminosity (P-L) relations. We obtain a P-R relation of log R = [0.767 +/- 0.009] log P + [1.091 +/- 0.011], only 1 sigma away from the relation obtained by Gieren et al. (1998). We therefore confirm their P-R relation at a level of Delta(log R) = +/- 0.02. We also derive an original calibration of the P-L relation, assuming the slopes derived by Gieren et al. (1998) from LMC Cepheids, alpha_K = -3.267 +/- 0.042 and alpha_V = -2.769 +/- 0.073. With a P-L relation of the form M = alpha (log P - 1) + beta, we obtain log P = 1 reference points of beta(K) = -5.904 +/- 0.063 and beta(V) = -4.209 +/- 0.075. Our calibration in the V band is statistically identical to the geometrical result of Lanoix et al. (1999).

description: The SL(2)-character variety X of a closed surface M enjoys a natural complex-symplectic structure invariant under the mapping class group G of M. Using the ergodicity of G on the SU(2)-character variety, we deduce that every G-invariant meromorphic function on X is constant. The trace functions of closed curves on M determine regular functions which generate complex Hamiltonian flows. For simple closed curves, these complex Hamiltonian flows arise from holomorphic flows on the representation variety generalizing the Fenchel-Nielsen twist flows on Teichmueller space and the complex quakebend flows on quasi-Fuchsian space. Closed curves in the complex trajectories of these flows lift to paths in the deformation space of complex-projective structures between different projective structures with the same holonomy (grafting). A pants decomposition determines a holomorphic completely integrable system on X. This integrable system is related to the complex Fenchel-Nielsen coordinates on quasi-Fuchsian space developed by Tan and Kourouniotis, and relate to recent formulas of Platis and Series on complex-length functions and complex twist flows.

description: Medium resolution (lambda/Delta lambda = 5000-10000) VLT-ISAAC M-band spectra are presented of 39 young stellar objects in nearby low-mass star forming clouds showing the 4.67 micron stretching vibration mode of solid CO. By taking advantage of the unprecedentedly large sample, high S/N ratio and high spectral resolution, similarities in the ice profiles from source to source are identified. It is found that excellent fits to all the spectra can be obtained using a phenomenological decomposition of the CO stretching vibration profile at 4.67 micron into 3 components. All observed interstellar CO profiles can thus be uniquely described by a model depending on only 3 linear fit parameters, indicating that a maximum of 3 specific molecular environments of solid CO exist under astrophysical conditions. A simple physical model of the CO ice is presented, which shows that the 2139.9 cm-1 component is indistinguishable from pure CO ice. It is concluded, that in the majority of the observed lines of sight, 60-90% of the CO is in a nearly pure form. In the same model the 2143.7 cm-1 component can possibly be explained by the longitudinal optical (LO) component of the vibrational transition in pure crystalline CO ice which appears when the background source is linearly polarised. Furthermore the absorption band from solid 13CO at 2092 cm-1 is detected towards IRS 51 in the Rho Ophiuchi cloud complex and an isotopic ratio of 12CO/13CO=68+/-10 is derived. It is shown that all the observed solid 12CO profiles, along with the solid 13CO profile, are consistent with grains with an irregularly shaped CO ice mantle simulated by a Continuous Distribution of Ellipsoids (CDE), but inconsistent with the commonly used models of spherical grains in the Rayleigh limit.

description: We investigate the effects of voltage induced spin-relaxation in a quantum dot in the Kondo regime. Using nonequilibrium perturbation theory, we determine the joint effect of self-energy and vertex corrections to the conduction electron T-matrix in the limit of transport voltage much larger than temperature. The logarithmic divergences, developing near the different chemical potentials of the leads, are found to be cut off by spin-relaxation rates, implying that the nonequilibrium Kondo-problem remains at weak coupling as long as voltage is much larger than the Kondo temperature.

description: This study investigates how independent podcasting functions as
a transformative medium for peacebuilding in contemporary society.
It explores how podcasting, distinct from traditional broadcasting,
empowers individuals to share personal narratives, amplify
marginalized voices, and cultivate inclusive dialogue on complex
societal issues. Drawing upon participatory culture and
peacebuilding frameworks, the research highlights podcasting’s
ability to foster empathy, challenge dominant media narratives, and
promote collective memory through accessible digital storytelling.
Unlike conventional media, which often operate under institutional
constraints, podcasts are produced with minimal resources and offer
creators flexibility, authenticity, and direct engagement with
audiences. This decentralized model enables diverse perspectives to
emerge and fosters community-driven discourse around human
rights, freedom, social justice, and identity. Through qualitative
content analysis of selected Arabic podcast episodes, the study
identifies key themes such as the transformative power of voice, the
importance of inner peace as a foundation for societal harmony, and
the subjective experience of freedom. The findings underscore
podcasting’s role in reshaping public discourse, especially in regions
where mainstream media may be restricted. Ultimately, this paper
positions independent podcasting as a vital tool in promoting peace,
inclusivity, and dialogue in a fragmented media landscape, and as a
dynamic platform for grassroots activism and cultural transformation
in the Arab world and beyond.
On electron-hole symmetry and phase separation in some electron doped cuprates

description: We conclude from the analysis of the experimental NMR data for electron-doped cuprates that the Coulomb effects caused by doping lead to dynamical spatial phase separation that contributes to the nuclear spin relaxation. Remarkable, the "infinite-layer" Sr0.9La0.1CuO2 reveals unexpected electron-hole symmetry. Its 63^Cu nuclear spin relaxation rate is the sum of a constant and the temperature dependent dissipation components, moreover, the latter turns out to be identical to the 1/63^T_1(T)-behavior in the stoichiometric hole-type compound YBa2Cu4O8. Connection to fluctuations of a magnetic sub-phase is discussed.

description: We have studied correlations in the speckle patterns generated by the scattering of perfect optical vortex (POV) beams and used them for producing a new-class of coherence functions, namely Bessel coherence functions. Higher (zeroth) order Bessel coherence functions have been realized in cross (auto)-correlation between the speckle patterns generated by the scattering of perfect vortex beams of different orders. We have also studied the propagation of produced Bessel coherence functions and characterized their divergence with respect to the radius of their first ring for different orders m=0--4. We observed that the divergence varies linearly with the order of the coherence function. We provide the exact analytical expression for the auto-correlation as well as cross-correlation functions for speckle patterns. Our experimental results are in good agreement with the analytical results.

description: Transverse mass and rapidity distributions for charged pions, charged kaons, protons and antiprotons are reported for sqrt{s_NN}=200 GeV pp and Au+Au collisions at RHIC. The transverse mass distributions are rapidity independent within |y|<0.5, consistent with a boost-invariant system in this rapidity interval. Spectral shapes and relative particle yields are similar in pp and peripheral Au+Au collisions and change smoothly to central Au+Au collisions. No centrality dependence was observed in the kaon and antiproton production rates relative to the pion production rate from medium-central to central collisions. Chemical and kinetic equilibrium model fits to our data reveal strong radial flow and relatively long duration from chemical to kinetic freeze-out in central Au+Au collisions. The chemical freeze-out temperature appears to be independent of initial conditions at RHIC energies.

description: The availability of a number of new interferometric measurements of Main Sequence and subgiant stars makes it possible to calibrate the surface brightness relations of these stars using exclusively direct angular diameter measurements. These empirical laws allow to predict the limb darkened angular diameters theta_LD of dwarfs and subgiants using their dereddened Johnson magnitudes, or their effective temperature. The smallest intrinsic dispersions of sigma < 1% on theta_LD are obtained for the relations based on the K and L magnitudes, for instance log theta_LD = 0.0502 (B-L) + 0.5133 - 0.2 L or log theta_LD = 0.0755 (V-K) + 0.5170 - 0.2 K. Our calibrations are valid between the spectral types A0 and M2 for dwarf stars (with a possible extension to later types when using the effective temperature), and between A0 and K0 for subgiants. Such relations are particularly useful to estimate the angular size of calibrators for long baseline interferometry from readily available broadband photometry.

Zur Entstehung und Altersstellung der Travertine, limnischen Sedimente und fluviatilen Terrassen im Gebiet der Mittleren Nera und des Corno (Umbrien, Mittelitalien)

Year: 1968

description: Im Nera- und Cornotal östlich von Terni (Mittelitalien) wurden drei Gebiete im Maßstab 1 :25 000 geologisch spezialkartiert. Dabei zeigte es sich u. a., daß in den Tälern abgesetzte Travertinmassen die Ausbildung von normalen Terrassenabfolgen stark störten. Hiervon ausgehend wurde die Art der Entstehung und die Altersstellung der durch Travertinausfällung bedingten fluviatilen und limnischen Sedimente an einem rezenten (Marmore-Piediluco) und zwei fossilen Beispielen (Terni-Marmore und Triponzo) näher untersucht. Im einzelnen ergab sich u. a.: 1. Bei Marmore liegen in einem einheitlichen Talsystem durch den Einfluß einer Travertinbarre gleichaltrige Sedimente fluviatiler Genese und gleicher Zusammensetzung in Höhen, die eine Differenz von 150—160 m aufweisen. 2. Etwa 50 m über dem Fluß gelegene Terrassenreste sind bei Triponzo weniger als 3000 Jahre alt und gehören mit größter Wahrscheinlichkeit in die etruskische Zeit. 3. In einem Zeitraum von ca. 6000 Jahren (7000—1000 v. Chr.) setzten sich bei Triponzo in einem durch eine Travertinbarre gestauten See 30—35 m mächtige limnische (Serie I) und 15—20 m mächtige limnisch-krenogen-fluviatile Sedimente ab (Serie II). Nach den i4C-Alters-bestimmungen betrug die durchschnittliche Sedimentationsgeschwindigkeit in der Serie I 0,7 cm/ Jahr, in der Serie II ca. 1 cm/Jahr. 4. Als auslösendes Moment für den Beginn oder das Aussetzen der Kaikabscheidung in den talversperrenden Travertinbarren können lokale Ereignisse und Gegebenheiten wirksam sein, wie z. B. Bergrutsche oder das Erreichen des Endes eines Engtales. Überregionale Klimaänderungen scheinen von untergeordneter Bedeutung zu sein. Der Wechsel Erosion-Akkumulation-Erosion usw. in den Flußtälern ist vorwiegend durch anthropogene Einflüsse, vor allem durch Waldrodung bedingt. Im Gebiet von Triponzo bewirkte z. B. wohl die erste starke Rodungstätigkeit in der etruskischen Zeit den Umschlag von der vorwiegend limnischen Sedimentation in eine rein fluviatile und vor allem die anschließende Erosion bis auf die Basis der Unteren Terrasse. Jüngere Erosionsphasen sind in diesem Gebiet vielleicht durch die Entwaldung in römischer und mittelalterlicher Zeit hervorgerufen worden. 5. In engen Tälern der Kalksteingebiete des Mittelmeerraumes ist es nicht möglich, Terrassen-und Verebnungsreste nach ihren Höhenlagen und der gleichartigen petrographischen Zusammensetzung zu parallelisieren. Bei dem Versuch, über alte Talbodenreste derartiger Täler die quartäre Sedimentfüllung intramontaner Becken mit den quartären Ablagerungen der Hauptflüsse oder mit marinen Bildungen zu verknüpfen, ist also, abgesehen von den Fehlerquellen, die durch tektonische Verstellungen gegeben sind, größte Vorsicht geboten.

description: As the quality of the available galaxy cluster data improves, the models fitted to these data might be expected to become increasingly complex. Here we present the Bayesian approach to the problem of cluster data modelling: starting from simple, physically motivated parameterised functions to describe the cluster's gas density, gravitational potential and temperature, we explore the high-dimensional parameter spaces with a Markov-Chain Monte-Carlo sampler, and compute the Bayesian evidence in order to make probabilistic statements about the models tested. In this way sufficiently good data will enable the models to be distinguished, enhancing our astrophysical understanding; in any case the models may be marginalised over in the correct way when estimating global, perhaps cosmological, parameters. In this work we apply this methodology to two sets of simulated interferometric Sunyaev-Zel'dovich effect and gravitational weak lensing data, corresponding to current and next-generation telescopes. We calculate the expected precision on the measurement of the cluster gas fraction from such experiments, and investigate the effect of the primordial CMB fluctuations on their accuracy. We find that data from instruments such as AMI, when combined with wide-field ground-based weak lensing data, should allow both cluster model selection and estimation of gas fractions to a precision of better than 30 percent for a given cluster.

description: The importance of national physical and cultural characteristics in the formulation of a Research and Education Support System (RESS) is restated and the physical and cultural characteristics of the Caricom farming community briefly described. The purposes of RESSs interrelationships between fusion of science and technology versus institutional integration of research and education for agricultural development in the 20th century are discussed. Structural features of RESS in Caricom are evaluated in the light of these discussions. Current, fragmented management of support systems for agricultural development in Caricom are examined and an alternative framework for integrated management of the RESS proposed. The framework is based on fusion of the publicly funded national and regional institutions of agricultural research with national institutions of formal (schools of agriculture) and non-formal (extension services) education. It is perceived that the major problems in implementing the alternative framework at national and regional levels are conceptual. At national level, the problems revolve around convincing national governments of the efficacy of integrating institutions of research and education for accelerated agricultural development. The regional problems emerge from difficulty in accepting the notion that a regional institution of research can be effectively replaced by a regional system for management (mandating, networking and evaluation) of regional projects in national institutions, albeit at reduced costs.

A remedy for constraint growth in Numerical Relativity

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Rapid growth of constraints is often observed in free evolutions of highly gravitating systems. To alleviate this problem we investigate the effect of adding spatial derivatives of the constraints to the right hand side of the evolution equations, and we look at how this affects the character of the system and the treatment of boundaries. We apply this technique to two formulations of Maxwell's equations, the so-called fat Maxwell and the Knapp-Walker-Baumgarte systems, and obtain mixed hyperbolic-parabolic problems in which high frequency constraint violations are damped. Constraint-preserving boundary conditions amount to imposing Dirichlet boundary conditions on constraint variables, which translate into Neumann-like boundary conditions for the main variables. The success of the numerical tests presented in this work suggests that this remedy may bring benefits to fully nonlinear simulations of General Relativity.

Thermal Pure Quantum Matrix Product States Recovering a Volume Law Entanglement

description: We propose a way to construct a thermal pure quantum matrix product state (TPQ-MPS) that can simulate finite temperature quantum many-body systems with a minimal numerical cost comparable to the matrix product algorithm for the ground state. The MPS was originally designed for the wave function with area-law entanglement. However, by attaching the auxiliary sites to the edges of the random matrix product state, we find that the degree of entanglement is automatically tuned so as to recover the volume law of the entanglement entropy that characterizes the TPQ state. The finite temperature physical quantities of the transverse Ising and the spin-1/2 Heisenberg chains evaluated by a TPQ-MPS show excellent agreement even for bond dimension $\sim 10$-$20$ with those of the exact results.

description: We construct an approximation to field theories on the noncommutative torus based on soliton projections and partial isometries which together form a matrix algebra of functions on the sum of two circles. The matrix quantum mechanics is applied to the perturbative dynamics of scalar field theory, to tachyon dynamics in string field theory, and to the Hamiltonian dynamics of noncommutative gauge theory in two dimensions. We also describe the adiabatic dynamics of solitons on the noncommutative torus and compare various classes of noncommutative solitons on the torus and the plane.

description: Die abschließende Auswertung der Arbeiten zur Aufnahme der Geologischen Karte 1 : 50.000 der Vogesen (Blätter Bruyeres und Epinal) hat bestätigt, daß der mittlere Teil der westlichen Vogesen von zumindest drei aufeinanderfolgenden Vereisungen betroffen war. Vor allem die Randlagen der dritten Vereisung sind in den Tälern von Mosel, Ognon und Moselotte und im Gebiet um Le Tholy nachgewiesen. Unter Bezug auf die für Grand Pile und Les Echets aufgestellten Stratigraphien kann man die dritte Vereisung des Moselbeckens dem Würm-Hochglazial zuordnen. Daraus ergibt sich mindel- bzw. rißzeitliches Alter für die vorausgehenden Vereisungen.

Fitting Pulsar Wind Tori

Subjects: subject: Astrophysics (astro-ph)

description: CXO imaging has shown that equatorial tori, often with polar jets, are very common in young pulsar wind nebulae (PWNe). These structures are interesting both for what they reveal about the relativistic wind itself and for the (nearly) model-independent measurement of the neutron star spin orientation they provide. The later is a particularly valuable probe of pulsar emission models and of neutron star physics.We describe here a procedure for fitting simple 3-D torus models to the X-ray data which provides robust estimates of the geometric parameters. An application to 6 PWN tori gives orientations, PWN shock scales and post-shock wind speeds along with statistical errors. We illustrate the use of these data by commenting on the implications for kick physics and for high energy beaming models.

description: 'The trend is your friend' is a common saying, the difficulty lies in determining if and when you are in a trend. Is the trend strong enough to trade? When does the trend reverse and how are you going to determine this? We will try and answer at least some of these questions here. We are deriving a novel indicator to measure the power of a trend using digital signal processing techniques, separating the Signal from the Noise. We apply these to examples as well as real data and evaluate the accuracy of these and the relation to PNL performance of the 'Volatility Index' trend following algorithm devised by J. Welles Wilder Jr. in 1978.

description: Because of increasing amounts of intermittent and distributed generators in power systems, many demand response programs have been developed to schedule flexible energy consumption. However, proper benchmarks for comparing these methods are lacking, especially when decisions are made based on information which is repeatedly updated. This paper presents a new benchmarking tool designed to bridge this gap. Surveys that classify flexibility planning algorithms were an input to define the benchmarking standards. The framework can be used for different objectives and under diverse conditions faced by electricity energy stakeholders interested in flexibility scheduling algorithms. It includes a simulation environment that captures the evolution of look--ahead information, which enables comparing online planning and scheduling algorithms. The benchmarking tool is used to test seven planning algorithms measuring their performance under uncertain market conditions. The results show the importance of online decision making, the influence of data quality on the algorithm performance, the benefit of using robust and stochastic programming approaches, and the necessity of trustworthy benchmarking.

description: A systematic study of neutron-hole strength in the N = 81 nuclei 137Ba, 139Ce, 141Nd and 143Sm is reported. The single-neutron removal reactions (p,d) and (3He,4He) were measured at energies of 23 and 34 MeV, respectively. Spectroscopic factors were extracted from measured cross sections through a distorted-wave Born approximation analysis and centroids of single-particle strength have been established. The change in these centroid energies as a function of proton number have been compared to calculations of the monopole shift for the s1/2 and h11/2 orbitals, where the majority of the strength has been observed. Significant fragmentation of strength was observed for the d and g7/2 orbitals, particularly for the latter orbital which is deeply bound, with summed strengths that indicate a significant amount lies outside of the measured excitation energy range.

Für acht der untersuchten Proben ergibt sich eine gute Übereinstimmung zwischen den Th/U- und den ESR-Altern, zwei Proben waren aufgrund extrem hoher Mangan-Gehalte nicht ESR-datierbar und in drei Fällen ergaben sich deutliche Diskrepanzen. Travertine aus dem Riß/Würm Interglazial haben ein Alter von ca. 100.000 a, die des vorletzten Interglazial zeigen ein Alter von 200.000 a und etwas darüber die des drittletzten Interglazials weisen ein Alter von über 300.000 a auf.

description: We investigate hadron production in deep inelastic lepton-nucleus scattering in the kinematic regime of the HERMES experiment. Our calculations are carried out in the framework of a BUU transport model which contains the Lund event generators PYTHIA and FRITIOF for the simulation of high-energy elementary interactions. For the first time we consistently use the complete four-dimensional information of the Lund string break up vertices as input for our transport theoretical studies of (pre)hadronic final state interactions. We compare our results with experimental HERMES data on charged hadron attenuation.
