description: Τα τελευταία χρόνια, η ραγδαία αύξηση των κρουσμάτων μεταδοτικών ασθενειών σε παγκόσμια κλίμακα, καθώς και η απειλή μιας ενδεχόμενης τρομοκρατικής επίθεσης με χρήση βιολογικών παραγόντων, αναδεικνύουν την ανάγκη για έγκαιρη και έγκυρη ανίχνευση ενός ξεσπάσματος σε πραγματικό χρόνο. Η έγκαιρη ανίχνευση μιας επιδημικής έξαρσης προϋποθέτει τη συλλογή δεδομένων, την ανάλυση και ερμηνεία τους σε πραγματικό χρόνο. Την τελευταία δεκαετία έχει γίνει σημαντική πρόοδος ως προς την ταχύτητα συλλογής και την ποιότητα των δεδομένων, ενώ για την ανάλυσή τους εφαρμόζονται αποτελεσματικά οι μέθοδοι του στατιστικού ελέγχου διεργασίας. Στην παρούσα εργασία, περιγράφονται αναλυτικά διάφορες τεχνικές στατιστικών ελέγχων διεργασίας, μοντέλα προσαρμογής και μέτρα έγκαιρης ανίχνευσης των εξάρσεων, δίνοντας παραδείγματα εφαρμογής τους σε πραγματικά δεδομένα.
description: The emergence of new infectious diseases at a global scale, as well as bioterrorism attack, have highlighted the need for early event detection. In order to detect disease outbreaks as soon as possible, both real-time data collection and interpretation are required. Over the last decade, important advances in setting up techniques for real-time data collection and statistical process control methods have been applied efficiently for early event detection. In the present dissertation, we provide a short presentation of statistical process control techniques, adapting models and early event detection measures, giving illustrative examples for disease outbreak detection in real data.

description: The purpose of this paper is to investigate experimental and numerical dynamic responses of a preloaded vibro-impacting Hertzian contact under sinusoidal excitation. Dynamic response under random excitation is analysed in the second part of this paper. A test rig is built corresponding to a double sphere-plane contact preloaded by the weight of a moving cylinder. Typical response curves are obtained for several input levels. Time traces and spectral contents are explored. Both amplitude and phase of harmonics of the dynamic response are investigated. Linearised resonance frequency and damping ratio are identified from the almost linear behaviour under very small input amplitude. Increasing the external input amplitude, the softening behaviour induced by Hertzian nonlinear stiffness is clearly demonstrated. Resonance peak is confined in a narrow frequency range. Jump discontinuities are identified for both amplitude and phase responses. Forced response spectrum exhibits several harmonics because of nonlinear Hertzian restoring force. Numerical simulations show a very good agreement with experimental results. For higher input amplitude, system exhibits vibro-impacts. Loss of contact non-linearity clearly dominates the dynamic behaviour of the vibroimpacting contact and leads to a wide frequency range softening resonance. Spectral content of the response is dominated by both the first and the second harmonics. Evolution of the experimental downward jump frequency versus input amplitude allows the identification of the nonlinear damping law during intermittent contact. Simulations of the vibroimpacting Hertzian contact are performed using a shooting method and show a very good agreement with experimental results.

description: Due to the lack of structure, scholarly knowledge remains hardly accessible for machines. Scholarly knowledge graphs have been proposed as a solution. Creating such a knowledge graph requires manual effort and domain experts, and is therefore time-consuming and cumbersome. In this work, we present a human-in-the-loop methodology used to build a scholarly knowledge graph leveraging literature survey articles. Survey articles often contain manually curated and high-quality tabular information that summarizes findings published in the scientific literature. Consequently, survey articles are an excellent resource for generating a scholarly knowledge graph. The presented methodology consists of five steps, in which tables and references are extracted from PDF articles, tables are formatted and finally ingested into the knowledge graph. To evaluate the methodology, 92 survey articles, containing 160 survey tables, have been imported in the graph. In total, 2,626 papers have been added to the knowledge graph using the presented methodology. The results demonstrate the feasibility of our approach, but also indicate that manual effort is required and thus underscore the important role of human experts.

description: Abstract Purpose of this study is the presentation of the life insurance and the special character that can be hired. In the first part of the study, an analysis of the general principles of this type of contract is made, reporting several separations both in terms of the risk and the person insured and particular attention is paid to the right of redemption and the special case of suicide. Then there is reference at the specific forms that life insurance contracts can take, with emphasis on those that enjoy elements of investment. The third part focuses on group insurance of the personnel of an enterprise by its employer, focusing further on the position of the insured worker in case of termination or amendment of the contract and also the fate of group insurance in case of a possible transfer of the enterprise and therefore change of the face of the employer. Finally, at the fourth and final part of the study, solvency issues of insurance companies are developed, such as those formed by taking into consideration the state supervision and control in conjunction with the European Union Directives, and also the consequences of insurance company’s withdrawal of concession, paying particular attention to the insurance liquidation and the fate of insurance contracts.
Giant Planet Accretion and Migration: Surviving the Type I Regime

description: In the standard model of gas giant planet formation, a large solid core (~ 10 times the Earth's mass) forms first, then accretes its massive envelope (100 or more Earth masses) of gas. However, inward planet migration due to gravitational interaction with the proto-stellar gas disk poses a difficulty in this model. Core-sized bodies undergo rapid "Type I" migration; for typical parameters their migration timescale is much shorter than their accretion timescale. How, then, do growing cores avoid spiraling into the central star before they ever get the chance to become gas giants? Here, we present a simple model of core formation in a gas disk which is viscously evolving. As the disk dissipates, accretion and migration timescales eventually become comparable. If this happens while there is still enough gas left in the disk to supply a jovian atmosphere, then a window of opportunity for gas giant formation opens. We examine under what circumstances this happens, and thus, what predictions our model makes about the link between proto-stellar disk properties and the likelihood of forming giant planets.

description: The kinetics, dynamics and conformational specificities for the ionic Diels-Alder reaction (polar cycloaddition) of maleic anhydride with 2,3-dibromobutadiene radical ions have been studied theoretically using multisurface adiabatic reactive molecular dynamics. A competition of concerted and stepwise reaction pathways was found and both the s-cis and s-trans conformers of of the diene are reactive. The analysis of the minimum dynamic path of the reaction indicates that both, rotations and vibrations of the reactant molecules are important for driving the system towards the transition state. The rates were computed as $k = 5.1 \times 10^{-14}$ s$^{-1}$ for the s-cis and $k = 3.8 \times 10^{-14}$ s$^{-1}$ for the s-trans conformer of 2,3-dibromobutadiene at an internal temperature of 300 K. The present results are to be contrasted with the neutral variant of the title system in which only the gauche conformer of the diene was found to undergo a considerably slower, concerted and mostly synchronous reaction driven by the excitation of rotations. The results presented here inform detailed experimental studies of the dynamics of polar cycloadditions under single-collision conditions in the gas phase.
Attached growth nitrification using Ringlace media

Publisher: name: University of British Columbia
Year: 2009

description: This thesis reports on an attempt to grow nitrifying bacteria attached on the submerged growth media Ringlace® in the aerobic zone of a pilot scale Biological Enhanced Phosphorus Removal (BEPR) process treating municipal sewage. The Ringlace® media was a fibrous rope modified PVC material stretched over frames that were immersed into the process. Nitrification on the support media was meant to enhance overall process nitrifying capacity. The overall process operating parameters HRT, SRT, and DO were manipulated to investigate their effects on the nitrification rate of the bacteria attached to the support media. Growth on the media consisted of an array of higher life forms and bacteria. Worm infestation on the media appeared to increase with increased DO concentration. Cyclic anaerobic periods of 12 to 24 hours controlled worm infestations at operating DO levels of 3.5 mg/L and lower but proved to be unsuccessful at tested DO concentrations above that. Sludge settling in the test process improved over the control process during a run with 6 hour HRT, 4 day SRT, 5.5 mg/L DO level, and 18 °C temperature. During this run the control process average specific nitrification rate was 2 mg-N/gTSS-hr and the test process average rate was 0.5 mg-N/gTSS-hr. This run had the highest DO level of the experiment and the Ringlace® support media had the highest amount of worms observed on it for the entire experiment. It is believed that the significant reduction in nitrification rate and the improved sludge settling were a result of interference from the worms. The results of batch testing Ringlace® frames removed from the flow through system throughout the experiment showed the biomass attached to the Ringlace® support media never exhibited specific ammonia uptake rate significantly greater than zero at the 5 % significance level. The suspended growth portion did display specific ammonia uptake rates which were approximately the same as rates reported in the literature for similar suspended growth studies. In selected batch tests the biomass on the media was shown to take up soluble carbon indicated by BOD5 measurements.

description: Non linear dynamic behaviour of a normally excited preloaded Hertzian contact (including possible contact losses) is investigated using an experimental test rig. It consists on a double sphere plane contact loaded by the weight of a rigid moving mass. Contact vibrations are generated by a external Gaussian white noise and exhibit vibroimpact responses when the input level is sufficiently high. Spectral contents and statistics of the stationary transmitted normal force are analysed. A single-degree-of-freedom non linear oscillator including loss of contact and Hertzian non linearities is built for modelling the experimental system. Theoretical responses are obtained by using the stationary Fokker-Planck equation and also Monte Carlo simulations. When contact loss occurrence is very occasional, numerical results shown a very good agreement with experimental ones. When vibroimpacts occur, results remain in reasonable agreement with experimental ones, that justify the modelling and the numerical methods described in this paper. The contact loss non linearity appears to be rather strong compared to the Hertzian non linearity. It actually induces a large broadening of the spectral contents of the response. This result is of great importance in noise generation for a lot of systems such as mechanisms using contacts to transform motions and forces (gears, ball-bearings, cam systems, to name a few). It is also of great importance for tribologists preoccupied to prevent surface dammage.

description: One very common type of fake news is satire which comes in a form of a news website or an online platform that parodies reputable real news agencies to create a sarcastic version of reality. This type of fake news is often disseminated by individuals on their online platforms as it has a much stronger effect in delivering criticism than through a straightforward message. However, when the satirical text is disseminated via social media without mention of its source, it can be mistaken for real news. This study conducts several exploratory analyses to identify the linguistic properties of Arabic fake news with satirical content. We exploit these features to build a number of machine learning models capable of identifying satirical fake news with an accuracy of up to 98.6%.

description: The scope of the present study was to address issues concerning the intrinsic orientation in the classroom. Nine hundred eighty Greek elementary students (grades fifth and sixth) participated in the study while 40 of them had learning disabilities. Significant group differences were found concerning the dimen¬sions of intrinsic orientation in their classroom and the achievement. Students without learning disabilities showed higher intrinsic motivation and greater school achievement than students with learning disabilities. Support was found that intrinsic orientation is positively and significantly related to school achievement with the exception of the subscale «Curiosity/Interest» and the correlation between “Independent Mastery” and Reading in the case of students with learning disabilities.

description: We consider an arbitrary linear elliptic first--order differential operator A with smooth coefficients acting between sections of complex vector bundles E,F over a compact smooth manifold M with smooth boundary N. We describe the analytic and topological properties of A in a collar neighborhood U of N and analyze various ways of writing A|U in product form. We discuss the sectorial projections of the corresponding tangential operator, construct various invertible doubles of A by suitable local boundary conditions, obtain Poisson type operators with different mapping properties, and provide a canonical construction of the Calderon projection. We apply our construction to generalize the Cobordism Theorem and to determine sufficient conditions for continuous variation of the Calderon projection and of well--posed selfadjoint Fredholm extensions under continuous variation of the data.

description: The notion of language test usefulness is expressed by Bachman & Palmer (1996:18) in the following way: Usefulness= Reliability-Validity+ Authenticity + Interactiveness + Impact + Practicality. The present paper will devote more time to the subject of authenticity In order to evaluate the language test in terms of authenticity we should examine the tasks and the texts, of which the examination material consists. Each task and each text of a test can be analysed through authenticity grids proposed. Two separate grids are proposed, one for measuring text authenticity and one for task authenticity, each one consisting of a series of criteria. Using these grids, a qualitative and quantitative evaluation of texts and tasks in terms of authenticity can be achieved.

description: The quantification of quantum entanglement is a central issue in quantum information theory. Recently, Gao \emph{et al}. ( \href{http://dx.doi.org/10.1103/PhysRevLett.112.180501}{Phys. Rev. Lett. \textbf{112}, 180501 (2014)}) pointed out that the maximum of entanglement measure of the permutational invariant part of $ρ$ ought to be a lower bound on entanglement measure of the original state $ρ$, and proposed that this argument can be used as an additional requirement for (multipartite) entanglement measures. Whether any individual proposed entanglement measure satisfies the requirement still has to prove. In this work, we show that most known entanglement measures of bipartite quantum systems satisfy the new criterion, include all convex-roof entanglement measures, the relative entropy of entanglement, the negativity, the logarithmic negativity and the logarithmic convex-roof extended negativity. Our results give a refinement in quantifying entanglement and provide new insights into a better understanding of entanglement properties of quantum systems.

description: La traduzione di poesia medievale in Italia ha avuto notevole sviluppo negli ultimi venti anni, attraverso l’incremento dell’attività dei traduttori e la promozione di un confronto su questioni di ordine teorico o metodologico, strettamente legate al tema dell’attualizzazione del testo medievale. In questo quadro, il contributo di Giuseppe Sansone ha svolto un ruolo di primo rilievo, attraverso un’attività ininterrotta che conta la pubblicazione di scritti di indirizzo critico-teorico e di cinque antologie di lirica medievale di diversi ambiti linguistici – occitano, spagnolo, catalano, galego e, in misura minore, francese –, offrendo modelli e appunti di metodo nei quali competenze scientifiche e filologiche si coniugano con una sensibilità estetica d’autore, guidata dall’obiettivo primario di una rifondazione del testo poetico nella sua letterarietà, dove la traduzione in versi si propone come testo dotato di una propria autonomia estetica.

Over the last twenty years the translation of medieval poetry in Italy has had considerable development due to the increased activity of the translators; besides, a debate on theoretical or methodological issues closely related to the theme of updating medieval texts has been promoted. In this context, the contribution of Giuseppe Sansone and his continuous activity has played a key role: he published critical-theoretical essays and five anthologies of medieval lyrics from different linguistic areas – Provençal, Spanish, Catalan, Galician and, to a lesser extent, French – thus offering models and methodological suggestions in which scientific and philological skills combine with aesthetic sensibility, driven from the primary method of re-founding the poetic text in its literary property, in which the verse translation is proposed as a text with its own aesthetic autonomy.

description: Talk at 32nd Texas Symposium. With increasing significance, the H0-tension between the Local Distance Ladder and Planck ΛCDM-analysis of the CMB points to a new principle of cosmological spacetime. Distinct from conventional extrapolations of general relativity in the Solar system, cosmological spacetime contains heat as a relic of the Big Bang based on Planck scale structures in black hole spacetimes. A path integral formulation produces a system of equations that satisfy T-duality in the Friedmann scale factor - a new symmetry in the Hubble expansion H(z) \simeq (1+(6/5)OmegaM0[(1+z)ˆ5-1])ˆ{1/2}/(1+z). It satisfies H0 \simeq 73 km/s/Mpc, q0 \simeq -1, OmegaM0 \simeq 0.25 relevant to tensions in (H0,q0,S8). [Based on van Putten, 2021, Phys. Lett. B, 823, 13637; 2020, MNRAS 491, L6.]

description: Objective: This paper presents a review of artificial intelligence (AI) methods in developing a system forpredicting the development of infectious diseases in humans, along with the formulation of key principlesfor the step-by-step implementation of these methods.Materials and Methods: The study begins with an assessment of the relevance of applying AI techniquesand methods to detect infected individuals in various scenarios. This is followed by a systematic review ofrelevant literature and research in the field of identifying methods to detect conditions in humans thatdeviate from normal, utilizing search engines such as Google Scholar and PubMed.Main Findings: Infectious diseases impose a significant burden on individuals in the modern world due totheir long-lasting consequences both during and after the illness. Consequently, there is an ongoing needto explore novel methods and approaches for diagnosing infectious diseases at their early stages ofdevelopment. One of the most promising directions in contemporary medicine is the application ofartificial intelligence in the diagnosis and prognosis of infectious diseases. Through the use of machinelearning algorithms, AI systems can analyze vast amounts of data and discern patterns that are not easilyidentifiable through manual examination. This facilitates the early detection of infectious diseases and aidsin preventing their spread. The development of an artificial intelligence-based system capable of providinganswers regarding the potential infection of specific individuals or groups, as well as the risk of contagionto others, is a highly relevant task. Such a system could employ video recordings and/or photographs fromcameras to analyze human movement patterns through machine learning techniques. The development ofsuch a system could be especially beneficial for security organizations and healthcare institutionsresponsible for public health.

description: Generalized linear models (GLMs) have been used quite effectively in the modeling of a mean response under nonstandard conditions, where discrete as well as continuous data distributions can be accommodated. The choice of design for a GLM is a very important task in the development and building of an adequate model. However, one major problem that handicaps the construction of a GLM design is its dependence on the unknown parameters of the fitted model. Several approaches have been proposed in the past 25 years to solve this problem. These approaches, however, have provided only partial solutions that apply in only some special cases, and the problem, in general, remains largely unresolved. The purpose of this article is to focus attention on the aforementioned dependence problem. We provide a survey of various existing techniques dealing with the dependence problem. This survey includes discussions concerning locally optimal designs, sequential designs, Bayesian designs and the quantile dispersion graph approach for comparing designs for GLMs.

description: The aim of the present thesis was the study of the attitudes of primary school teachers in the prefecture of Thessaloniki towards the bilingualism of Roma students. Roma children constitute a unique example of bilingual students, for the reason that their bilingualism is the product of a remarkably complex historical, political as well as social situation. In this thesis, we explored the specific characteristics that compose the identity of the Greek Roma population, as well as the attitude the school assumes towards Roma students. Furthermore, we conducted a very short survey about the attitudes of primary school teachers in the prefecture of Thessaloniki towards the bilingualism of Roma students.

description: Σκοπός της διατριβής ήταν η μελέτη της σύμβασης μάνατζμεντ, μια νέα μορφή συναλλαγών της σύγχρονης οικονομίας. Εξετάσαμε την έννοια της διοίκησης και του ρόλου που επιτελεί σε μία οικονομική οντότητα. Στη συνέχεια παρουσιάσαμε αναλυτικά τη νομική φύση της σύμβασης μάνατζμεντ και τις μορφές εμφάνισής της στις συναλλαγές. Ακόμη αναφερθήκαμε στην διάκριση της σύμβασης μάνατζμεντ από συγγενείς θεσμούς. Ένα άλλο θέμα που θίξαμε ήταν τα ζητήματα που προκύπτουν από τη σύναψη της εν λόγω σύμβασης μεταξύ δυο νομικών προσώπων με γνώμονα το εταιρικό δίκαιο. Ασχοληθήκαμε επίσης με την ευθύνη του μάνατζερ στο πλαίσιο άσκησης της διαχείρισης βάσει της σύμβασης μάνατζμεντ. Τέλος αναφερθήκαμε επιγραμματικά στο μάνατζμεντ μη κερδοσκοπικών οργανισμών και τις συμβάσεις μάνατζμεντ στον δημόσιο τομέα.
description: The aim of the present thesis was the study of the management agreement, a new form of trade in modern economy. We examined the meaning of management and leadership and their role in a financial entity. Then we presented the legal nature of management agreements and their forms in the trades. We analyzed the difference of management agreement from relevant forms of agreements. We also examined the issues resulting from the examined management agreement between two legal entities focusing on the Company Law. We also presented the liability of the manager within the frameworks of the leadership on the basis of the management agreement. Finally, we shortly presented the management of nonprofit organizations and management agreements in the Public Sector.

description: The recently discovered phosphorus-rich stars pose a challenge to stellar evolution and nucleosynthesis theory, as none of the existing models can explain their extremely peculiar chemical abundances pattern. Apart from the large phosphorus enhancement, such stars also show enhancement in other light (O, Mg, Si, Al) and heavy (e.g., Ce) elements. We have obtained high-resolution optical spectra of two optically bright phosphorus-rich stars (including a new P-rich star), for which we have deter-mined a larger number of elemental abundances (from C to Pb). We confirm the unusual light-element abundance pattern with very large enhancements of Mg, Si, Al, and P, and possibly some Cu enhancement, but the spectra of the new P-rich star is the only one to reveal some C(+N) enhancement.When compared to other appropriate metal-poor and neutron-capture enhanced stars, the two P-rich stars show heavy-element overabundances similar to low neutron density s-process nucleosynthesis,with high first- (Sr, Y, Zr) and second-peak (Ba, La, Ce, Nd) element enhancements (even some Pb enhancement in one star) and a negative [Rb/Sr] ratio. However, this s-process is distinct from the one occurring in asymptotic giant branch (AGB) stars. The notable distinctions encompass larger[Ba/La] and lower Eu and Pb than their AGB counterparts. Our observations should guide stellar nucleosynthesis theoreticians and observers to identify the P-rich star progenitor, which represents anew site for s-process nucleosynthesis, with important implications for the chemical evolution of our Galaxy.

description: We investigate the phenomenon of the transverse breaking of symmetry of Gaussian lasers transmitted through dielectrics, showing for which incidence conditions and beam parameters it can be observed in optical experiments. The numerical analysis, done by using the integral form of the transmitted beam at the lower interface of a dielectric prism, shows, for incidence approaching the critical region, a laser planar trapping. By using an analytic approximation for the intensity of lower transmitted beam, we model the wave front curvature by a closed expression which depends on the refractive index, on the geometrical properties of the dielectric block, and, finally, on the incidence angle of the incoming beam. The analytic formula shows an excellent agreement with the numerical analysis and it could be useful in future experimental implementations.

description: The purpose of the study was the application and the evaluation of a school health education intervention program, aiming at attitude improvement towards physical activity participation and at the adoption of healthy nutritional habits. The school based intervention program lasted ten weeks and was applied to 87 children in the 5th and 6th grade of primary school. The study was held through questionnaires and all scales had acceptable levels of internal consistency. The results indicated that, after the intervention program, the pupils had more positive attitudes towards healthy eating and scored significantly higher in their participation in mild and moderate physical activity. Within the limitations of the study, the data show that school health education programs can help pupils establish lifelong healthy habits. Promoting healthy habits and physical activity behaviors during childhood may prevents some of the diseases later in life and improve quality of life.

description: Due to the massively increasing amount of available geospatial data and the need to present it in an understandable way, clustering this data is more important than ever. As clusters might contain a large number of objects, having a representative for each cluster significantly facilitates understanding a clustering. Clustering methods relying on such representatives are called center-based. In this work we consider the problem of center-based clustering of trajectories. In this setting, the representative of a cluster is again a trajectory. To obtain a compact representation of the clusters and to avoid overfitting, we restrict the complexity of the representative trajectories by a parameter l. This restriction, however, makes discrete distance measures like dynamic time warping (DTW) less suited. There is recent work on center-based clustering of trajectories with a continuous distance measure, namely, the Fréchet distance. While the Fréchet distance allows for restriction of the center complexity, it can also be sensitive to outliers, whereas averaging-type distance measures, like DTW, are less so. To obtain a trajectory clustering algorithm that allows restricting center complexity and is more robust to outliers, we propose the usage of a continuous version of DTW as distance measure, which we call continuous dynamic time warping (CDTW). Our contribution is twofold: 1. To combat the lack of practical algorithms for CDTW, we develop an approximation algorithm that computes it. 2. We develop the first clustering algorithm under this distance measure and show a practical way to compute a center from a set of trajectories and subsequently iteratively improve it. To obtain insights into the results of clustering under CDTW on practical data, we conduct extensive experiments.

The thermal Sunyaev-Zel'dovich Signature of Baryons in the Local Universe

description: Using cosmological hydrodynamical simulations, we investigate the prospects of the thermal Sunyaev-Zel'dovich (tSZ) effect to detect the missing baryons in the local universe. We find that at least 80% of the tSZ luminosity is generated in collapsed structures, and that $\sim$ 70% of the remaining diffuse tSZ luminosity (i.e., $\sim 15$% of the total) comes from overdense regions with $δ_{gas}>$10, such as filaments and superclusters. The gas present in slightly overdense and underdense regions with $δ_{gas} < 10$, despite making up 50% of the total baryon budget, leaves very little tSZ signature: it gives rise to only $\sim$ 5% of the total tSZ luminosity. Thus, future Cosmic Microwave Background (CMB) observations will be sensitive to, at best, one half of the missing baryons, improving the current observational status, but still leaving one half unobserved. Since most of the tSZ is generated in haloes, we find a tight correlation between gas pressure and galaxy number density. This allows us to predict the CMB Comptonization from existing galaxy surveys and to forecast the tSZ effect from the local structures probed by the Two Micron All Sky Survey (2MASS) galaxy catalog.

description: We study the operadic and categorical formulations of (conformal) full field algebras. In particular, we show that a grading-restricted $\R\times \R$-graded full field algebra is equivalent to an algebra over a partial operad constructed from spheres with punctures and local coordinates. This result is generalized to conformal full field algebras over $V^L\otimes V^R$, where V^L and V^R are two vertex operator algebras satisfying certain finiteness and reductivity conditions. We also study the geometry interpretation of conformal full field algebras over $V^L\otimes V^R$ equipped with a nondegenerate invariant bilinear form. By assuming slightly stronger conditions on V^L and V^R, we show that a conformal full field algebra over $V^L\otimes V^R$ equipped with a nondegenerate invariant bilinear form exactly corresponds to a commutative Frobenius algebra with a trivial twist in the category of $V^L\otimes V^R$-modules. The so-called diagonal constructions of conformal full field algebras are given in tensor-categorical language.

Fermi polaron in a dissipative bath with spin-orbit coupling

description: We study the polaron problem of an impurity immersed in a dissipative spin-orbit coupled Fermi gas via a non-self-consistent T-matrix method. We first propose an experimental scheme to realize a spin-orbit coupled Fermi bath with dissipation, and show that such a system can be described by a non-Hermitian Hamiltonian that contains an imaginary spin-flip term and an imaginary constant shift term. We find that the non-Hermiticity will change the single particle dispersion of the bath gas, and modify the properties of attractive and repulsive polarons such as energy, quasi-particle residue, effective mass, and decay rate. We also investigate the Thouless criteria corresponding to the instability of the polaron molecule transition, which suggests a molecule state is more facilitated with stronger bath dissipation. Finally, we consider the case with finite impurity density and calculate the interaction between polarons. Our result extends the study of polaron physics to non-Hermitian systems and may be realized in future experiment.

description: Continuum strain energy functions are developed for soft biological tissues that possess long fibrillar components. The treatment is based on the model of an elastica, which is our fine scale model, and is homogenized in a simple fashion to obtain a continuum strain energy function. Notably, we avoid solving the full fourth-order, nonlinear, partial differential equation for the elastica by resorting to other assumptions, kinematic and energetic, on the response of the individual, elastica-like fibrils.
