description: The application of Wilson's Numerical Renormalization Group (NRG) method to dissipative quantum impurity models, in particular the sub-ohmic spin-boson model, has led to conclusions regarding the quantum critical behavior which are in disagreement with those from other methods and which are by now recognized as erroneous. The errors of NRG remained initially undetected because NRG delivered an internally consistent set of critical exponents satisfying hyperscaling. Here we discuss how the conspiracy of two errors - the Hilbert-space truncation error and the mass-flow error - could lead to this consistent set of exponents. Remarkably, both errors, albeit of different origin, force the system to obey naive scaling laws even when the physical model violates naive scaling. In particular, we show that a combination of the Hilbert-space truncation and mass-flow errors induce an artificial non-analytic term in the Landau expansion of the free energy which dominates the critical behavior for bath exponents s<1/2.

description: In this paper, we compare components of the horizontal flow below the solar surface in and around regions consisting of rotating and non-rotating sunspots. Our analysis suggests that there is a significant variation in both components of the horizontal flow at the beginning of sunspot rotation as compared to the non-rotating sunspot. In most cases, the flows in surrounding areas are relatively small. However, there is a significant influence of the motion on flows in an area closest to the sunspot rotation.

description: We construct a Type II$_\infty$ von Neumann algebra that describes the large $N$ physics of single-trace operators in AdS/CFT in the microcanonical ensemble, where there is no need to include perturbative $1/N$ corrections. Using only the extrapolate dictionary, we show that the entropy of semiclassical states on this algebra is holographically dual to the generalized entropy of the black hole bifurcation surface. From a boundary perspective, this constitutes a derivation of a special case of the QES prescription without any use of Euclidean gravity or replicas; from a purely bulk perspective, it is a derivation of the quantum-corrected Bekenstein-Hawking formula as the entropy of an explicit algebra in the $G \to 0$ limit of Lorentzian effective field theory quantum gravity. In a limit where a black hole is first allowed to equilibrate and then is later potentially re-excited, we show that the generalized second law is a direct consequence of the monotonicity of the entropy of algebras under trace-preserving inclusions. Finally, by considering excitations that are separated by more than a scrambling time we construct a "free product" von Neumann algebra that describes the semiclassical physics of long wormholes supported by shocks. We compute Rényi entropies for this algebra and show that they are equal to a sum over saddles associated to quantum extremal surfaces in the wormhole. Surprisingly, however, the saddles associated to "bulge" quantum extremal surfaces contribute with a negative sign.

description: We investigate the dynamics of r modes at amplitudes in the nonlinear regime for rapidly but uniformly rotating neutron stars with a polytropic equation of state. For this, we perform three-dimensional relativistic hydrodynamical simulations, making the simplifying assumption of a fixed spacetime. We find that for initial dimensionless amplitudes around three, r modes decay on timescales around ten oscillation periods, while at amplitudes of order unity, they are stable over the evolution timescale. Together with the decay, a strong differential rotation develops, conserving the total angular momentum, with angular velocities in the range 0.5..1.2 of the initial one. By comparing two models, we found that increasing rotation slows down the r-mode decay. We present r-mode eigenfunctions and frequencies, and compare them to known analytic results for slowly rotating Newtonian stars. As a diagnostic tool, we discuss conserved energy and angular momentum for the case of a fixed axisymmetric background metric and introduce a measure for the energy of non-axisymmetric fluid oscillation modes.

description: This manuscript is an edited and refined version of the lecture script for a one-semester graduate course given originally at the PhD school in the Institute of Physics of Polish Academy of Sciences in the Spring/Summer semester of 2022. The course expects from the student only a basic knowledge on graduate-level quantum mechanics. The script itself is largely self-contained and could be used as a textbook on the topic of open quantum systems. The program of this course is based on a novel approach to the description of the open system dynamics: It is showed how the environmental degrees of freedom coupled to the system can be represented by a multi-component quasi-stochastic process. Using this representation one constructs the super-quasi-cumulant (or super-qumulant) expansion for the system's dynamical map -- a parametrization that naturally lends itself for the development of a robust and practical perturbation theory. Thus, even an experienced researcher might find this manuscript of some interest.

description: Objective Radiologic imaging of the allograft pancreatic duct dilatation is an uncommon multifactorial finding that is not well described. The purpose of this investigation is to determine the clinical correlation of this finding. Design Retrospective study. Setting University Hospital, USA. Subjects One hundred forty five simultaneous pancreas-kidney transplants have been performed for treatment of type I diabetes mellitus and end-stage renal disease between February 1993 and December 1999 at the University of Miami. Main outcome measures In 5 recipients, the pancreatic duct was noted to be dilated by ultrasound 1-18 months post-transplant. Results In all 5 recipients a Foley catheter was placed as the first line of treatment. This reduced the size of the pancreatic duct in one patient, who presented with normal serum amylase and lipase and hyperglycemia. A pancreas biopsy done with Foley catheter in place showed fibrosis with no evidence of rejection. Four patients with dilated pancreatic duct presented with increased serum amylase and lipase; however improvement of the pancreatic duct dilatation was seen only after anti-rejection therapy. One of the patients developed recurrence of pancreatic duct dilatation and a video-urodynamic study subsequently demonstrated voiding with abdominal straining and no detrusor activity. He ultimately underwent enteric conversion with resolution of pancreatic duct dilatation. Conclusions This infrequent complication of dilated transplant pancreatic duct could be multifactorial. It could suggest the diagnosis of reflux pancreatitis, which should resolve with bladder decompression. In fact, 1 patient presented with reflux pancreatitis caused by external sphincter detrusor pseudodyssynergia. However, this ultrasound finding may also be associated with pancreas rejection (4/5 patients).

description: Context We have isolated five stable clones from a primary culture of Syrian golden hamster pancreatic duct epithelial cells and have designated them as CK1 through CK5. Design Here we describe the ability of two of these, CK1 and CK5, to metabolize the pancreas carcinogen N-nitrosobis(2-oxopropyl)amine. The metabolism was assessed as the production of mutated V79 cells in a CK cell/V79 co-culture set up. Results At a dose of 0.1 mM N-nitrosobis(2-oxopropyl)amine, the CK1 cells produced 82.3 ± 17.2 mutants/106 survivors while the CK5 cells produced only 33.2 ± 10.8 mutants/106 survivors, both are mean ± SD (n = 8). Furthermore, both cell types responded differently to two inducers of cytochrome P450 activity, namely Arochlor 1254 and EtOH. Arochlor 1254 treatment did not affect the metabolizing ability of CK1 cells while EtOH treatment resulted in a twofold increase in the mutation frequency. Arochlor and EtOH treatment inhibited the ability of CK5 cells to metabolize N-nitrosobis(2-oxopropyl)amine. Conclusions These data show that the duct epithelium of the pancreas is a multi-cellular tissue and the different cell types within the epithelium have different abilities to metabolize xenobiotic chemicals.

description: We present the temperature- and thickness-dependent structural and morphological evolution of strain induced transformations in highly-strained epitaxial BiFeO3 films deposited on LaAlO3 (001) substrates. Using high-resolution X-ray diffraction and temperature-dependent scanning-probe-based studies we observe a complex temperature- and thickness-dependent evolution of phases in this system. A thickness-dependent transformation from a single monoclinically distorted tetragonal-like phase to a complex mixed-phase structure in films with thicknesses up to ~200 nm is the consequence of a strain-induced spinodal instability in the BiFeO3/LaAlO3 system. Additionally, a breakdown of this strain-stabilized metastable mixed-phase structure to non-epitaxial microcrystals of the parent rhombohedral structure of BiFeO3 is observed to occur at a critical thickness of ~300 nm. We further propose a mechanism for this abrupt breakdown that provides insight into the competing nature of the phases in this system.

description: In order to understand gender injustice and combat gender discrimination on media platforms in Europe, we need to understand what gender injustice currently looks like and -importantly- what it can look like in the future. How can we imagine gender in Europe? We will use the conceptual frame of gendered othering to analyze gender in relation to social media platforms. To start, we dive deeper into theoretical reflections on gender. We explain what gender and sex and their differences are. This is done with an eye for intersectionality. We need to use the intersectional lens to then expand on the meaning of gendered othering. After having explained this concept, we consider the data from the EUMEPLAT project. We can see how different studies within the project have contributed to an understanding of gender in social media platforms. This allows us to understand the current situation with regards to gender, othering and social media. Now, we know what gender injustice currently looks like on social media. However, part of our research question remains; what can it look like in the future? For this, we have produced and gathered various possible future scenarios.
We worked on the basis that grounded theory and data are conceptualised as a site of ideological negotiations and we looked for similar discourses and reoccurring arguments. After analyzing them from a discourse theoretical perspective (Foucault, 1975; Arribas-Ayllon & Walkerdine, 2008), we were able to identify three main themes.
These themes show us in different ways what gender (in)justice (on social media) can look like in 20 or 30 years from now. Some of the future scenarios are more or less desirable. All of them show where we as a European society could end up being.
Understanding future scenarios and possibilities in relation to gender is important because it entails what we have to do in the present to either prevent or encourage different future scenarios from happening.

description: Most NLP tasks are modeled as supervised learning and thus require labeled training data to train effective models. However, manually producing such data at sufficient quality and quantity is known to be costly and time-intensive. Current research addresses this bottleneck by exploring a novel paradigm called zero-shot learning via dataset generation. Here, a powerful LLM is prompted with a task description to generate labeled data that can be used to train a downstream NLP model. For instance, an LLM might be prompted to "generate 500 movie reviews with positive overall sentiment, and another 500 with negative sentiment." The generated data could then be used to train a binary sentiment classifier, effectively leveraging an LLM as a teacher to a smaller student model. With this demo, we introduce Fabricator, an open-source Python toolkit for dataset generation. Fabricator implements common dataset generation workflows, supports a wide range of downstream NLP tasks (such as text classification, question answering, and entity recognition), and is integrated with well-known libraries to facilitate quick experimentation. With Fabricator, we aim to support researchers in conducting reproducible dataset generation experiments using LLMs and help practitioners apply this approach to train models for downstream tasks.

Variable Cascade

description: DDI-Lifecycle utilises the variable cascade to organise and describe data from conception to collection. The organisation of conceptual variables and conceptual variable groups allows comparison of data at different time points, universes, representations and many other dimensions through concordance tables and is well suited to iterative data collected as panels, cohorts, repeated surveys and periodic administrative files.Within a single study design, such comparisons are straight-forward to describe and comprehend. Whilst it is possible to extend the comparison between studies or from other sources such as administrative data, by creating groups of conceptual variables, conveying to the user (human or machine) the data collection dimensions will likely require the alignment of this metadata also.This is potentially a significant challenge for multi-study metadata infrastructures or national statistical agencies which hold data from diverse sources. The presentation will discuss the outputs from a workshop organised between CLOSER, INSEE and Constance that seeks to address these issues

description: Objective To assess the sensitivity and specificity of the serum carboxypeptidase B activation peptide in diagnosing and determining the severity of acute pancreatitis. Patients Twenty consecutive patients with acute pancreatitis were studied on admission to the Emergency Room: 11 patients had mild pancreatitis, and 9 patients, severe pancreatitis. Twenty consecutive patients with non-pancreatic acute abdomen and 20 healthy subjects were also studied. Main outcome measures Serum carboxypeptidase B activation peptide was determined using radioimmunoassay. Results Nineteen of the 20 patients with acute pancreatitis (95.0%) had serum carboxypeptidase B activation peptide concentrations above the upper reference limit, whereas 1 of the 20 patients with non-pancreatic acute abdomen (5.0%) and none of the healthy subjects had serum levels of this protein above the upper reference limit. The serum carboxypeptidase B activation peptide concentrations of patients with severe acute pancreatitis were significantly higher than those of patients with mild acute pancreatitis on the 2nd (P=0.044) and 3rd days (P=0.028) of the study. The overall sensitivity and specificity of carboxypeptidase B activation peptide in assessing the severity of acute pancreatitis were 84.6% and 59.4%, respectively. Conclusions Serum carboxypeptidase B activation peptide may be used simultaneously both to diagnosis and assess the severity of acute pancreatitis on admission to the Emergency Room.

description: Numerical optimization for the inverse design of photonic structures is a tool which is providing increasingly convincing results -- even though the wave nature of problems in photonics makes them particularly complex. In the meantime, the field of global optimization is rapidly evolving but is prone to reproducibility problems, making it harder to identify the right algorithms to use. This paper is thought as a tutorial on global optimization for photonic problems. We provide a general background on global optimization algorithms and a rigorous methodology for a physicist interested in using these tools -- especially in the context of inverse design. We suggest algorithms and provide explanations for their efficiency. We provide codes and examples as an illustration than can be run online, integrating quick simulation code and Nevergrad, a state-of-the-art benchmarking library. Finally, we show how physical intuition can be used to discuss optimization results and to determine whether the solutions are satisfactory or not.

description: We study the interplay between symmetry representations of the physical and virtual space on the class of tensor network states for critical spins systems known as field tensor network states (fTNS). These are by construction infinite dimensional tensor networks whose virtual space is described by a conformal field theory (CFT). We can represent a symmetry on the physical index as a commutator with the corresponding CFT current on the virtual space. By then studying this virtual space representation we can learn about the critical symmetry protected topological properties of the state, akin to the classification of symmetry protected topological order for matrix product states. We use this to analytically derive the critical symmetry protected topological properties of the two ground states of the Majumdar-Ghosh point with respect to the previously defined symmetries.

description: Quantum chromodynamics (QCD) at non-zero isospin chemical potential is studied in a canonical approach by analyzing systems of fixed isospin number density. To construct these systems, we develop a range of new algorithms for performing the factorially large numbers of Wick contractions required in multi-hadron systems. We then use these methods to study systems with the quantum numbers of up to 72 $π^+$'s on three ensembles of gauge configurations with spatial extents $L\sim$ 2.0, 2.5 and 3.0 fm, and light quark masses corresponding to a pion mass of {390 MeV}. The ground state energies of these systems are extracted and the volume dependence of these energies is utilized to determine the two- and three- body interactions amongst $π^+$'s. The systems studied correspond to isospin densities of up to $ρ_I\sim 9\ {\rm fm}^{-3}$ and probe isospin chemical potentials, $μ_I$, in the range $m_π \lsim μ_I\ \lsim 4.5\ m_π$, allowing us to investigate aspects of the QCD phase diagram at low temperature and for varying isospin chemical potential. By studying the energy density of the system, we provide numerical evidence for the conjectured transition of the system to a Bose-Einstein condensed phase at $μ_I\ \gsim m_π$.

description: Learning a privacy-preserving model from sensitive data which are distributed across multiple devices is an increasingly important problem. The problem is often formulated in the federated learning context, with the aim of learning a single global model while keeping the data distributed. Moreover, Bayesian learning is a popular approach for modelling, since it naturally supports reliable uncertainty estimates. However, Bayesian learning is generally intractable even with centralised non-private data and so approximation techniques such as variational inference are a necessity. Variational inference has recently been extended to the non-private federated learning setting via the partitioned variational inference algorithm. For privacy protection, the current gold standard is called differential privacy. Differential privacy guarantees privacy in a strong, mathematically clearly defined sense. In this paper, we present differentially private partitioned variational inference, the first general framework for learning a variational approximation to a Bayesian posterior distribution in the federated learning setting while minimising the number of communication rounds and providing differential privacy guarantees for data subjects. We propose three alternative implementations in the general framework, one based on perturbing local optimisation runs done by individual parties, and two based on perturbing updates to the global model (one using a version of federated averaging, the second one adding virtual parties to the protocol), and compare their properties both theoretically and empirically.

description: Objective To clarify the regulation of protein kinase C on glucose-mediated insulin secretion. Main outcome measures We examined the effect of protein kinase C on the cytosolic free Ca2+ concentration ([Ca2+]i) and the activity of Ca2+-activated K+ channels (KCa-channel) in the insulinoma cell line, HIT-T15. Results Glucose at a concentration of 10 mmol/L increased the secretion of insulin. This increase was partly inhibited by 1 nmol/L staurosporine, a protein kinase C inhibitor. Staurosporine (1 nmol/L) also attenuated the glucose-induced elevations in [Ca2+]i. On the contrary, glibenclamide (100 nmol/L) specifically blocked ATP-sensitive K+ channels, and increased both [Ca2+]i and insulin secretion, but staurosporine had no effect on them. Patch clamp studies showed that 10 mmol/L glucose almost completely blocked KCa channel activity, an effect that was reversed by 1 nmol/L staurosporine. Phorbol 12-myristate 13-acetate (1 mmol/L), a protein kinase C activator, also decreased KCa channel activity. Conclusions These results indicate that the activation of protein kinase C is involved in the glucose-induced release of insulin by modulating K+ channel function in HIT-T15 cells.

description: This edition of the Digest is the eleventh report released to date.
description: The Digest is arranged by subject matter, starting with general industry data (venues, games, charitable gaming licences), followed by revenues; revenue distributions; gambling participation; problem gambling prevalence; problem gambling assistance; and on-site information and support at gaming venues. Data in each section are presented in tables and figures. Accompanying text describes the data and highlights some of its more salient features. While considerable effort is made to ensure that the data in a given table or figure are comparable across provinces, this is not always possible due to differences in record keeping and other factors. Unless stated otherwise, all data pertain to fiscal 2012-13 (April 1st, 2012 to March 31st, 2013). Revenues have been rounded off to the nearest thousand. After the quantitative component of the Digest described above, there is a section entitled, Organization and Management of Gambling in Canada. The section provides an overview of the operation, regulation and management of gambling in each province, and is designed to give readers a more encompassing look at the similarities and differences in how gambling is run across the country.

description: The spin-1 quantum Ising systems with three-spin interactions on two-dimensional triangular lattices are studied by mean-field method. The thermal variations of order parameters and phase diagrams are investigated in detail. The stable, metastable and unstable branches of the order parameters are obtained. According to the stable conditions at critical point, we find that the systems exhibit tricritical points. With crystal field and biquadratic interactions, the system has rich phase diagrams with single reentrant or double reentrant phase transitions for appropriate ranges of the both parameters.

Using line and ellipse features for rectification of broadcast hockey video
Creators: name: Gupta, Ankur
Publisher: name: University of British Columbia

description: To use hockey broadcast videos for automatic game analysis, we need to compensate for camera viewpoint and motion. This can be done by using features on the rink to estimate the homography between the observed rink and a geometric model of the rink, as specified in the appropriate rule book (top down view of the rink). However, occlusion due to players, wide range of camera motion and frames with few reliable key-points pose a significant challenge for robustness and accuracy of the solution. In this work, we describe a new method to use line and ellipse features along with key-point based matches to estimate the homography. We combine domain knowledge (i.e., rink geometry) with an appearance model of the rink to detect these features accurately. This overdetermines the homography estimation to make the system more robust. We show this approach is applicable to real world data and demonstrate the ability to track long sequences on the order of 1,000 frames.

description: Context We studied behavior of the subcutaneously implanted pancreatic tumors and the process of metastasis using syngeneic Syrian golden hamsters. Design HaP-T1, a cell line derived from nitrosamine-induced pancreatic cancer in Syrian golden hamsters was used for this experiment. Thirty-five animals were divided into two groups: subcutaneous cell inoculation and subcutaneous tissue implantation. The tumor tissue was obtained from subcutaneously implanted cancer cells. One month after implantation, the tumors were resected and studied histopathologically. The animals were followed-up weekly by palpation of the peripheral lymph nodes in order to identify local recurrence. After death, necropsy was performed. Liver, lungs and pancreas specimens were taken for histopathogical study and detection of K-ras point mutation using the PCR/RFLP method. Results The mean survival time in the subcutaneous cell inoculation group was 151±17.5 days, and in the subcutaneous tissue implantation group was 137±12.9 days. During the follow-up, 13 subcutaneously cell inoculated hamsters (86.7%) had right axillary lymph node metastasis while subcutaneously tissue implanted hamsters did not show any palpable lymph nodes. After necropsy, 10 of the 20 subcutaneously tissue implanted animals (50%) showed metastases in the lungs at the histopathological level. However, 16 of the 20 subcutaneously tissue implantated animals (80%) showed K-ras point mutation in the lung specimens. The lungs of the animals of the subcutaneous cell inoculation group did not show any metastases. No metastases were found in the liver or the pancreas in either group. Conclusion This study suggests that homologous subcutaneous cell inoculation and subcutaneous tissue implantation models showed completely different patterns of metastasis. These models may aid further research to clarify the mechanisms of metastasis in pancreatic cancer.

Exploiting the orthogonal constraints offered by high-precision ages and chemistry

Publisher: name: Zenodo

description: In the era of large spectroscopic surveys, high-quality spectra can contribute to our understanding of the Galactic chemical evolution, not only providing high-precision abundances of elements belonging to the different nucleosynthesis channels, but also giving constraints to one of the most elusive quantities in astrophysics, i.e. stellar age.
In this talk, I will briefly show how high-quality spectra (HARPS@TNG and FIES@NOT) of a sample of Kepler stars, of which we know high-precision ages from asteroseismology, can enhance our ability to calibrate stellar age-chemistry relationships. The orthogonal constraints offered by age from asteroseismology, precise chemistry from ground-based high-resolution spectroscopy, and dynamics from the Gaia mission can open the door to a more accurate understanding of the Galactic chemical evolution, tracing the processes of chemical enrichment with time.

description: Samenvatting
De BPSD-DS-2 is een informanten-interview over dementiegerelateerde gedragsveranderingen, met 52 vragen verdeeld over 11 klinisch gedefinieerde secties. Deze secties geven inzicht in de problematiek van de cliënt en mogelijke begeleiding. Er zijn afkappunten bepaald waarmee kan worden vastgesteld of er sprake is van klinisch relevante gedragsveranderingen. Dit dient altijd in combinatie met andere informatiebronnen te worden bekeken.
De 11 secties van gedrag in de BPSD-DS-2 zijn:

Angstig gedrag
Slaapproblemen
Prikkelbaar gedrag
Koppig gedrag
Rusteloos- en stereotiep gedrag
Agressief gedrag
Apathisch gedrag
Depressief gedrag
Psychotisch gedrag (waanideeën en hallucinaties)
Ontremd gedrag
Eet- en drinkgedrag
Aan het eind van elke sectie wordt ook de ervaren zorglast door familieleden of zorgverleners geïnventariseerd. Op deze manier biedt de BPSD-DS-2 breed inzicht in de ernst van de problematiek en geeft zij richting aan het opstellen van een behandelplan en ondersteuning van zorgverleners, familieleden en cliënten.
De BPSD-DS-2 is gevalideerd middels uitgebreid wetenschappelijk onderzoek en blijkt te beschikken over een goed onderscheidend vermogen. De BPSD-DS-2 maakt een betrouwbaar onderscheid tussen volwassenen met een verstandelijke beperking zonder dementie, met dementie, maar ook met (vroege) signalen van dementie.

description: Device-independent (DI) protocols, such as DI conference key agreement (DICKA) and DI randomness expansion (DIRE), certify private randomness by observing nonlocal correlations when two or more parties test a Bell inequality. While most DI protocols are restricted to bipartite Bell tests, harnessing multipartite nonlocal correlations may lead to better performance. Here, we consider tripartite DICKA and DIRE protocols based on testing multipartite Bell inequalities, specifically: the Mermin-Ardehali-Belinskii-Klyshko (MABK) inequality, and the Holz and the Parity-CHSH inequalities introduced in the context of DICKA protocols. We evaluate the asymptotic performance of the DICKA (DIRE) protocols in terms of their conference key rate (net randomness generation rate), by deriving lower bounds on the conditional von Neumann entropy of one party's outcome and two parties' outcomes. For the Holz inequality, we prove a tight analytical lower bound on the one-outcome entropy and conjecture a tight lower bound on the two-outcome entropy. We additionally re-derive the analytical one-outcome entropy bound for the MABK inequality with a much simpler method and obtain a numerical lower bound on the two-outcome entropy for the Parity-CHSH inequality. Our simulations show that DICKA and DIRE protocols employing tripartite Bell inequalities can significantly outperform their bipartite counterparts. Moreover, we establish that genuine multipartite entanglement is not a precondition for multipartite DIRE while its necessity for DICKA remains an open question.

description: The aim of this study was to characterise the microstructural organisation of staple carbon fibre-reinforced polymer composites and to investigate their mechanical properties. Conventionally, fibre-reinforced materials are manufactured using continuous fibres. However, discontinuous fibres are crucial for developing sustainable structural second-life applications. Specifically, aligning staple fibres into yarn or tape-like structures enables similar usage to continuous fibre-based products. Understanding the effects of fibre orientation, fibre length, and compaction on mechanical performance can facilitate the fibres’ use as standard engineering materials. This study employed methods ranging from microscale to macroscale, such as image analysis, X-ray computed tomography, and mechanical testing, to quantify the microstructural organisations resulting from different alignment processing methods. These results were compared with the results of mechanical tests to validate and comprehend the relationship between fibre alignment and strength. The results show a significant influence of alignment on fibre orientation distribution, fibre volume fraction, tortuosity, and mechanical properties. Furthermore, different characteristics of the staple fibre tapes were identified and attributed to kinematic effects during movement of the sliver alignment unit, resulting in varying tape thicknesses and fuzzy surfaces.

description: We describe factor frequencies of the generalized Thue-Morse word t_{b,m} defined for integers b greater than 1, m greater than 0 as the fixed point starting in 0 of the morphism ϕ_{b,m} given by ϕ_{b,m}(k)=k(k+1)...(k+b-1), where k = 0,1,..., m-1 and where the letters are expressed modulo m. We use the result of A. Frid, On the frequency of factors in a D0L word, Journal of Automata, Languages and Combinatorics 3 (1998), 29-41 and the study of generalized Thue-Morse words by S.

description: From microscopic models, a Langevin equation can in general be derived only as an approximation. Two possible conditions to validate this approximation are studied. One is, for a linear Langevin equation, that the frequency of the Fourier transform should be close to the natural frequency of the system. The other is by the assumption of `slow' variables. We test this method by comparison with an exactly soluble model, and point out its limitations. We base our discussion on two approaches. The first is a direct, elementary treatment of Senitzky. The second is via a generalized Langevn equation as an intermediate step.
