description: In the first part of this letter we discuss electrodynamics of an excitonic condensate in a bilayer. We show that under certain conditions the system has a dominant energy scale and is described by the effective electrodynamics with "planar magnetic charges". In the second part of the paper we point out that a vortex liquid state in bilayer superconductors also possesses dipolar superfluid modes and establish equivalence mapping between this state and a dipolar excitonic condensate. We point out that a vortex liquid state in an N-layer superconductor possesses multiple topologically coupled dipolar superfluid modes and therefore represents a generalization of the dipolar superfluidity concept.

description: This is a poster that was presented that the MecaNano conference 2024. https://mecanano2024.sciencesconf.org/ 

In the field of nanoindentation, a critical challenge has been the lack of standardized terminology and data interpretation frameworks, hindering effective collaboration and replication of experiments across different laboratories. To address this, in this work a Nanoindentation ontology has been developed, offering a structured knowledge framework that not only facilitates the exchange of information but also supports the semantic documentation of experiments in an interoperable manner. Central to this ontology is the establishment of a widely accepted taxonomy for nanoindentation, which delineates a clear and organized classification of concepts, processes, and entities within this domain, from sample preparation to postprocessing procedures. Conceived as part of the NanoMECommons European project, the CHAMEO ontology endeavors to harmonize the protocols used in characterisation studies. Rooted in the CHAMEO framework, the Nanoindentation ontology leverages a unified language and approach to data management, established by the CEN Workshop Agreement (CWA 17815) and the Characterisation Data (CHADA) documentation scheme. This framework is meticulously crafted to encapsulate the shared elements found across a spectrum of characterisation methods. Its design allows for the strategic development of specific ontologies tailored to individual methodologies through the thoughtful adaptation and refinement of CHAMEO's core components. This endeavor is a key component of the European Materials Modelling Council's (EMMC) ambitious initiative to forge a network of interconnected materials modelling ontologies, all anchored by the foundational principles of the Elementary Multiperspective Material Ontology (EMMO).
Parameter Dependence and Bell nonlocality

description: Bell's theorem asserts that no model that satisfies all of the plausible physical assumptions of outcome independence (OI), measurement independence (MI) and Parameter Independence (PI) can reproduce quantum mechanics. Here I find the optimum model that saturates CHSH inequality for the case that outcome independence and measurement independence hold but parameter dependence is allowed. I find the bound as a function of a measure of parameter dependence and show that the model proposed by [New Journal of Physics,12(8):083051] is optimal for one-way parameter dependence. The symbolic optimizations to find the saturating models are performed using the open source software Analytical Optimizer v1.0.

description: The main result of the paper is the theorem giving a sufficient condition for the existence of a bounded analytic projection onto a holomorphic family of (generally infinite-dimensional) subspaces (a holomorphic sub-bundle of a trivial bundle). This sufficient condition is also necessary in the case of finite dimension or codimension of the bundle. A simple lemma of N. Nikolski connects the existence of a bounded analytic projection with the Operator Corona Problem (existence of a bounded analytic left inverse for an operator-valued function), so as corollaries of the main result we obtain new results about the Operator Corona Problem. In particular, we find a new sufficient condition, a complete solution in the case of finite codimension, and, a solution of the generalized Corona Problem.

Η έρευνα διεξήχθη με τη συμπλήρωση ερωτηματολογίων αυτο-αναφοράς 92 ζευγαριών Ελλήνων. Στα αποτελέσματα παρατηρήθηκε ότι η θετική κοινωνική υποστήριξη σχετίστηκε αρνητικά με την ψυχολογική δυσφορία στις γυναίκες και θετικά με την ποιότητα γάμου και στα δύο φύλα. Η αρνητική κοινωνική υποστήριξη σχετίστηκε θετικά με την ψυχολογική δυσφορία και στα δύο φύλα και αρνητικά με την ποιότητα γάμου στις γυναίκες (με εξαίρεση την υποκλίμακα της επίρριψης ευθύνης στους άνδρες). Οι στρατηγικές αποφυγής σχετίστηκαν θετικά με την ψυχολογική δυσφορία στους άνδρες όπως και οι στρατηγικές αναζήτησης κοινωνικής υποστήριξης στις γυναίκες. Οι στρατηγικές συναισθηματικής προσέγγισης σχετίστηκαν αρνητικά με την ψυχολογική δυσφορία στις γυναίκες και θετικά με την ποιότητα γάμου στους άνδρες. Επιπρόσθετα, το τελικό μοντέλο έδειξε ότι οι στρατηγικές αντιμετώπισης του άγχους είναι σημαντικοί προβλεπτικοί παράγοντες της ψυχολογικής δυσφορίας και της ποιότητας γάμου και όχι η κοινωνική υποστήριξη. Τέλος, συζητούνται περιορισμοί της έρευνας καθώς και προτάσεις για εφαρμογή των αποτελεσμάτων.
description: The purpose of this research is to investigate possible correlations of positive and negative social support and coping strategies with psychological dysphoria and quality of marriage in couples with infertility problems. The research was conducted with the filling in of self-report questionnaires of 92 Greek couples. At the results, it was noted that positive social support was negativelely correlated with psychological dysphoria in women and positevely correlated with the quality of marriage in both sexes. There was a positive relation of negative social support with psychological dysphoria in both sexes and a negative relation with the quality of marriage in women (with the exception of blaming subscale in men). Avoidance coping strategies were positevely correlated with psychological dysphoria in men as seeking of emotional support coping strategies were positevely correlated with psychological dysphoria in women. Emotional approach coping strategies were found to be negatively correlated with phychological dysphoria in women and positevely corrlated with the quality of marriage in men. Moreover, the final model showed that coping strategies, but not social support, are significant predictive factors of psychological dysphoria and quality of marriage. Finally, limitations of the study and proposals for implementing the results are discussed.

description: We consider a variant of the BB84 protocol for quantum cryptography, the prototype of tomographically incomplete protocols, where the key is generated by one-way communication rather than the usual two-way communication. Our analysis, backed by numerical evidence, establishes thresholds for eavesdropping attacks on the raw data and on the generated key at quantum bit error rates of 10% and 6.15%, respectively. Both thresholds are lower than the threshold for unconditional security in the standard BB84 protocol.

description: Isospin-1/2 $Dπ$ scattering amplitudes are computed using lattice QCD, working in a single volume of approximately $(3.6\; \mathrm{fm})^3$ and with a light quark mass corresponding to $m_π\approx239$ MeV. The spectrum of the elastic $Dπ$ energy region is computed yielding 20 energy levels. Using the Lüscher finite-volume quantisation condition, these energies are translated into constraints on the infinite-volume scattering amplitudes and hence enable us to map out the energy dependence of elastic $Dπ$ scattering. By analytically continuing a range of scattering amplitudes, a $D_0^\ast$ resonance pole is consistently found strongly coupled to the $S$-wave $Dπ$ channel, with a mass $m\approx 2200$ MeV and a width $Γ\approx400$ MeV. Combined with earlier work investigating the $D_{s0}^\ast$, and $D_0^\ast$ with heavier light quarks, similar couplings between each of these scalar states and their relevant meson-meson scattering channels are determined. The mass of the $D_0^\ast$ is consistently found well below that of the $D_{s0}^\ast$, in contrast to the currently reported experimental result.

In-season prediction of batting averages: A field test of empirical Bayes and Bayes methodologies
Creators: name: Brown, Lawrence D.
Publisher: name: arXiv
Year: 2008
Subjects: subject: Applications (stat.AP)
subject: FOS: Computer and information sciences

description: Batting average is one of the principle performance measures for an individual baseball player. It is natural to statistically model this as a binomial-variable proportion, with a given (observed) number of qualifying attempts (called ``at-bats''), an observed number of successes (``hits'') distributed according to the binomial distribution, and with a true (but unknown) value of $p_i$ that represents the player's latent ability. This is a common data structure in many statistical applications; and so the methodological study here has implications for such a range of applications. We look at batting records for each Major League player over the course of a single season (2005). The primary focus is on using only the batting records from an earlier part of the season (e.g., the first 3 months) in order to estimate the batter's latent ability, $p_i$, and consequently, also to predict their batting-average performance for the remainder of the season. Since we are using a season that has already concluded, we can then validate our estimation performance by comparing the estimated values to the actual values for the remainder of the season. The prediction methods to be investigated are motivated from empirical Bayes and hierarchical Bayes interpretations. A newly proposed nonparametric empirical Bayes procedure performs particularly well in the basic analysis of the full data set, though less well with analyses involving more homogeneous subsets of the data. In those more homogeneous situations better performance is obtained from appropriate versions of more familiar methods. In all situations the poorest performing choice is the na\"{ı}ve predictor which directly uses the current average to predict the future average.

description: Background: Sepsis is life-threatening organ dysfunction caused by a dysregulated host response to infection. Inflammatory response and oxidative stress play an important role in the pathophysiological process of sepsis. Thioredoxin-1 (Trx-1) is a small ubiquitous thiol protein with redox/inflammation modulatory properties relevant to the pathogenesis of sepsis. We therefore investigated the expression level and significance of Trx-1, inflammatory factors and oxidative stress in peripheral blood of sepsis patients, and to explore Trx-1 relationship with inflammatory factors and oxidative stress. Methods: Plasma samples were collected from patients with sepsis and those with healthy control. Enzyme-linked immunosorbent assays (ELISA) were used to detect for interleukin (IL-1β), IL-6, tumor necrosis factor (TNF-α), E-selectin, endothelin-1 (ET-1), thioredoxin-1, C-reactive protein (CRP), procalcitonin (PCT) for human plasma samples; RT-PCR detection of Trx-1 and thioredoxin-interacting protein (TXNIP) mRNA levels. Colorimetric assay for glutathione (GSH) and malondialdehyde (MDA) expression level in peripheral blood of patients with sepsis; Disease severity was assessed as APACHE II. Results: The expression levels of Trx-1, inflammatory factors and oxidative stress in plasma of patients with sepsis were significantly increased, TXNIP opposite. Conclusion: Our results show that Trx-1 play important role in inflammation and oxidative stress in sepsis patients. Trx-1 may be a potential therapeutic target in sepsis.
Plasma concentrations of amino acids in rainbow trout (Oncorhynchus mykiss) in response to nutritional and feeding management
Creators: name: Tantikitti, Chutima
Publisher: name: University of British Columbia
Year: 2009

description: This study considered a number of dietary factors that may alter the balance and constancy of amino acid concentrations in the plasma of rainbow trout. Fish given five equal feedings per day had relatively constant plasma amino acid concentrations and deposited more protein and less lipid than did fish fed the same ration at one feeding per day. The rate at which amino acids from the single meal feeding entered the circulation was evidently in excess of the rate at which those amino acids could be utilized for immediate protein synthesis with the result that a higher proportion of them was catabolized and the carbon skeletons employed in lipid synthesis. Supplementation of dietary protein with lysine and methiorune in the free form resulted in more rapid appearance of these amino acids in the plasma than occurred with the intact dietary protein alone. A surge of plasma arginine, alanine, histidine, and lysine concentrations observed at 36 li after the fish were fed diets containing a mixture of protein sources suggested delayed digestion of particular proteins. Isonitrogenous substitution of free glycine for that supplied by gelatin delayed the time at which plasma glycine peaked postprandially compared with the response to the gelatin-containing diet. When a diet was supplemented with a mixture of free essential amino acids, elevated concentrations remained in the plasma and muscle pools as long as 26 h after feeding, indicating that dietary supplements of free amino acids may remain available for protein synthesis even when the fish are fed once daily. Plasma concentrations of free amino acids in fish fed different concentrations of dietary lipid indicated that dietary lipid at 24% of the diet had no effect of the lipid on digestion of protein or absorption of amino acids. Postprandial concentrations of plasma amino acids in fish fed fish meal that had been subjected to heat treatment showed that the predominant nutritional effect of protein denaturation was a reduction in availability of threonine and histidine. In conclusion, the responses of plasma amino acid concentrations to different dietary conditions observed in this study indicate that they provide a useful tool for investigating the effects of various nutritional factors on protein metabolism in fish.

description: The modeling of tsunami generation is an essential phase in understanding tsunamis. For tsunamis generated by underwater earthquakes, it involves the modeling of the sea bottom motion as well as the resulting motion of the water above it. A comparison between various models for three-dimensional water motion, ranging from linear theory to fully nonlinear theory, is performed. It is found that for most events the linear theory is sufficient. However, in some cases, more sophisticated theories are needed. Moreover, it is shown that the passive approach in which the seafloor deformation is simply translated to the ocean surface is not always equivalent to the active approach in which the bottom motion is taken into account, even if the deformation is supposed to be instantaneous.

description: We consider an interacting collective spin model known as coupled top (CT), exhibiting a rich variety of phenomena related to quantum transitions, ergodicity, and formation of quantum scars, discussed in [Phys. Rev. E 102, 020101(R) (2020)]. In this work, we present a detailed analysis of the different type of transitions in CT model, and find their connection with the underlying collective spin dynamics. Apart from the quantum scarring phenomena, we also identify another source of deviation from ergodicity due to the presence of non-ergodic multifractal states. The degree of ergodicity of the eigenstates across the energy band is quantified from the relative entanglement entropy as well as multifractal dimensions, which can be probed from non-equilibrium dynamics. Finally, we discuss the detection of non-ergodic behavior and different types of quantum scars using `out-of-time-order correlators', which has relevance in the recent experiments.
LoopIng: a template-based tool for predicting the structure of protein loops
Creators: name: Messih, Mario
name: Tramontano, Anna
Publisher: name: F1000Research
Year: 2015

description: Motivation:

Predicting the structure of protein loops is very challenging, mainly because they are not necessarily subject to strong evolutionary pressure. This implies that, unlike the rest of the protein, standard homology modeling techniques are not very effective in predicting their structure. However, loops are often involved in protein function by interacting with other molecules, hence inferring their structure is important for predicting protein structure as well as function.

Results:

We have developed a method, LoopIng, which uses both sequence and geometry related features (e.g. loop sequence, sequence similarity, stem distance, stem secondary structure and stem geometry). These features are used in a Random Forest (RF) machine learning regression model that is trained to select the loop template with the lowest predicted 3D distance from the target loop among a list of putative ones. LoopIng achieves significant enhancements (~ 1Å RMSD) over the most recently available template-based as well as ab-initio methods (i.e. LoopWeaver and DisGro, respectively). In addition, compared to LEAP, which is an ab-initio method, LoopIng is able to achieve similar accuracy for short loops (4-10 residues) and significantly better improvements for long loops (11-20 residues) while being orders of magnitude faster (1 minute/loop vs. 10 hours/loop). The quality of the predictions is robust to errors that unavoidably affect stem regions when these are modeled. The method returns a confidence score for the predicted template loops.

description: We demonstrate numerically calculated electromagnetic eigenmodes of a 3D dome cavity resonator that owe their shape and character entirely to the Goos-Haenchen effect. The V-shaped modes, which have purely TE or TM polarization, are well described by a 2D billiard map with the Goos-Haenchen shift included. A phase space plot of this augmented billiard map reveals a saddle-node bifurcation; the stable periodic orbit that is created in the bifurcation corresponds to the numerically calculated eigenmode, dictating the angle of its "V". A transition from a fundamental Gaussian to a TM V mode has been observed as the cavity is lengthened to become nearly hemispherical.

description: How to effectively and efficiently extract valid and reliable features from high-dimensional electroencephalography (EEG), particularly how to fuse the spatial and temporal dynamic brain information into a better feature representation, is a critical issue in brain data analysis. Most current EEG studies work in a task driven manner and explore the valid EEG features with a supervised model, which would be limited by the given labels to a great extent. In this paper, we propose a practical hybrid unsupervised deep convolutional recurrent generative adversarial network based EEG feature characterization and fusion model, which is termed as EEGFuseNet. EEGFuseNet is trained in an unsupervised manner, and deep EEG features covering both spatial and temporal dynamics are automatically characterized. Comparing to the existing features, the characterized deep EEG features could be considered to be more generic and independent of any specific EEG task. The performance of the extracted deep and low-dimensional features by EEGFuseNet is carefully evaluated in an unsupervised emotion recognition application based on three public emotion databases. The results demonstrate the proposed EEGFuseNet is a robust and reliable model, which is easy to train and performs efficiently in the representation and fusion of dynamic EEG features. In particular, EEGFuseNet is established as an optimal unsupervised fusion model with promising cross-subject emotion recognition performance. It proves EEGFuseNet is capable of characterizing and fusing deep features that imply comparative cortical dynamic significance corresponding to the changing of different emotion states, and also demonstrates the possibility of realizing EEG based cross-subject emotion recognition in a pure unsupervised manner.

description: Quantum imaging, one of the pillars of quantum technologies, is well-suited to study sensitive samples which require low-light conditions, like biological tissues. In this context, interaction-free measurements (IFM) allow us infer the presence of an opaque object without the photon interacting with the sample. Current IFM schemes are designed for single-pixel objects, while real-life samples are structured, multi-pixel objects. Here we extend the IFM imaging schemes to multi-pixel, semi-transparent objects, by encoding the information about the pixels into an internal degree of freedom, namely orbital angular momentum (OAM). This allows us to image the pixels in parallel. Our solution exhibits a better theoretical efficiency than the single-pixel case. Our scheme can be extended to other degrees of freedom, like the photon radial quantum number, in order to image 1D and 2D objects.

description: В статье поднимается актуальная проблема образования – оценка знаний обучающихся. Игнорирование логики приводит к неправильной интерпретации самого понятия «знания», а отсюда – искажённое, даже безнравственное, понимание сущности оценки знаний. Диалектический подход к образовательному процессу расширяет представление о сущности, формах и приёмах оценки знаний обучающихся и обогащает принципом материализации оценки.

description: We study the security of quantum string commitment (QSC) protocols with group covariant encoding scheme. First we consider a class of QSC protocol, which is general enough to incorporate all the QSC protocols given in the preceding literatures. Then among those protocols, we consider group covariant protocols and show that the exact upperbound on the binding condition can be calculated. Next using this result, we prove that for every irreducible representation of a finite group, there always exists a corresponding nontrivial QSC protocol which reaches a level of security impossible to achieve classically.

description: Motivated by the categorical-algebraic analysis of split epimorphisms of monoids, we study the concept of a special object induced by the intrinsic Schreier split epimorphisms in the context of a regular unital category with binary coproducts, comonadic covers and a natural imaginary splitting in the sense of our article [Intrinsic Schreier split extensions, Appl. Categ. Structures 28 (2020), 517--538]. In this context, each object comes naturally equipped with an imaginary magma structure. We analyse the intrinsic Schreier split epimorphisms in this setting, showing that their properties improve when the imaginary magma structures happen to be associative. We compare the intrinsic Schreier special objects with the protomodular objects, and characterise them in terms of the imaginary magma structure. We furthermore relate them to the Engel property in the case of groups and Lie algebras.

description: We classify radial timelike geodesic motion of the exterior non-extremal Kerr spacetime by performing a taxonomy of inequivalent root structures of the first order radial geodesic equation using a novel compact notation and by implementing the constraints from polar, time and azimuthal motion. Four generic root structures with only simple roots give rise to eight non-generic root structures when either one root becomes coincident with the horizon, one root vanishes or two roots becomes coincident. We derive the explicit phase space of all such root systems in the basis of energy, angular momentum and Carter's constant and classify whether each corresponding radial geodesic motion is allowed or disallowed from existence of polar, time and azimuthal motion. The classification of radial motion within the ergoregion for both positive and negative energies leads to 6 distinguished values of the Kerr angular momentum. The classification of null radial motion and near-horizon extremal Kerr radial motion are obtained as limiting cases and compared with the literature. We explicitly parametrize the separatrix describing root systems with double roots as the union of the following three regions that are described by the same quartic respectively obtained when (1) the pericenter of bound motion becomes a double root; (2) the eccentricity of bound motion becomes zero; (3) the turning point of unbound motion becomes a double root.

description: JPred4 is a part of a suite of analysis tools available from www.compbio.dundee.ac.uk. JPred4 is the latest version of the popular JPred protein secondary structure prediction server which provides predictions by the JNet algorithm, one of the most accurate methods for secondary structure prediction. In addition to protein secondary structure, JPred also makes predictions of solvent accessibility and coiled-coil regions. The JPred service runs up to 134,000 jobs per month and has carried out over 2 million predictions in total for users in 179 countries. The JPred4 web server has been re-implemented in the Bootstrap framework and JavaScript to improve its design, usability and accessibility from mobile devices with added REST API for programmable command-line access. JPred4 features higher accuracy, with a blind three-state (α-helix, β-strand and coil) secondary structure prediction accuracy of 82.0% while solvent accessibility prediction accuracy has been raised to 90% for residues <5% accessible. Reporting of results has been enhanced on the web-site and through the optional email summaries, batch submission results and REST API. Predictions are now presented in SVG format with options to view full multiple sequence alignments with and without gaps and insertions. Finally, the help-pages have been updated and tool-tips added as well as step-by-step tutorials.

description: We analyze the psu(2,2|4) supersymmetry algebra of a superstring propagating in the AdS_5 x S^5 background in the uniform light-cone gauge. We consider the off-shell theory by relaxing the level-matching condition and take the limit of infinite light-cone momentum, which decompactifies the string world-sheet. We focus on the psu(2|2)+psu(2|2) subalgebra which leaves the light-cone Hamiltonian invariant and show that it undergoes extension by a central element which is expressed in terms of the level-matching operator. This result is in agreement with the conjectured symmetry algebra of the dynamic S-matrix in the dual N=4 gauge theory.

description: Ως ακραίο ορίζεται ένα γεγονός που συμβαίνει σχετικά σπάνια, επηρεάζει όμως το περιβάλλον όπου εμφανίζεται. Η ανάγκη εντοπισμού, μέσω της πρόβλεψης, αυτών των γεγονότων απασχόλησε πολλούς ερευνητές τα τελευταία χρόνια. Στη συγκεκριμένη εργασία παρουσιάζονται οι μονοδιάστατες, διδιάστατες και πολυδιάστατες κατανομές ακραίων τιμών καθώς και δύο μέθοδοι εκτίμησης: η μέθοδος μέγιστης πιθανοφάνειας και η μέθοδος Bayes. Γίνεται εκτενής μελέτη της δεύτερης μεθόδου, καθώς είναι λιγότερο γνωστή στο πεδίο της εκτιμητικής. Οι κατανομές που μελετώνται είναι η Γενικευμένη Κατανομή Ακραίων Τιμών (GEV), η Gumbel και η Pareto. Στο πλαίσιο της εφαρμογής, στο περιβάλλον της γλώσσας R γίνεται μελέτη και εκτίμηση των παραμέτρων των παραπάνω κατανομών ακραίων τιμών με τη μέθοδο μέγιστης πιθανοφάνειας και εκτίμηση των παραμέτρων της κατανομής GEV με τη μέθοδο Bayes, για τη μονοδιάστατη περίπτωση. Επιπλέον, εκτιμώνται τα επίπεδα επανάληψης για συγκεκριμένες περιόδους επανάληψης. Χρησιμοποιείται επίσης η μέθοδος Monte Carlo (MCMC) για την προσομοίωση της μαρκοβιανής αλυσίδας στη μέθοδο Bayes. Τα δεδομένα της εφαρμογής προέρχονται απο 4 σταθμούς της Ανατολικής Ελλάδας και αναφέρονται σε ημερήσιες τιμές βροχόπτωσης. Καταλληλότερες κατανομές για την περιγραφή των ακραίων τιμών προέκυψαν η Pareto και η GEV, ενώ οι δύο μέθοδοι εκτίμησης είναι εξίσου κατάλληλες, με τη Bayes να υπερτερεί σε κάποια σημεία.
description: As extreme is defined an event that occurs relatively infrequently, therefore affects a lot the environment or the field where it occurs. The need for identification of these events, through forecasting, took the time of many researchers in recent years. In this project we present the univariate, bivariate, multivariate extreme value distributions and two estimation methods: the maximum likelihood method and the Bayes method. An extensive study of the second method is done, as it is less known in the field of estimation. The distributions studied are the Generalized Extreme Value distribution (GEV), Gumbel and Pareto distributions. Applying the theory introduced before, in statistical language R the parameters of all the above distributions are studied and being estimated through the maximum likelihood estimation method and the parameters of GEV distribution through the Bayes method, in the univariate case. In addition, we estimate the return levels for specified return periods. The Monte Carlo (MCMC) method is also used to simulate the Markov chain in Bayes method. The data used in this project cοme from 4 stations in Eastern Greece and refer to daily rainfall values. The appropriate distributions for describing the extremes seem to be the Pareto and GEV distributions, while the two estimation methods are equally suitable, although Bayes has a small advantage to some points.

description: An overview of microlocality in braided ribbon networks is presented. Following this, a series of definitions are presented to explore the concept of microlocality and the topology of ribbon networks. Isolated substructure of ribbon networks are introduced, and a theorem is proven that allows them to be relocated. This is followed by a demonstration of microlocal translations. Additionally, an investigation into macrolocality and the implications of invariants in braided ribbon networks are presented.
