description: We introduce Eulerian maps with blocked edges as a general way to implement statistical matter models on random maps by a modification of intrinsic distances. We show how to code these dressed maps by means of mobiles, i.e. decorated trees with labeled vertices, leading to a closed system of recursion relations for their generating functions. We discuss particular solvable cases in detail, as well as various applications of our method to several statistical systems such as spanning trees on quadrangulations, mutually excluding particles on Eulerian triangulations or the Ising model on quadrangulations.

description: There is long research interest in electron-induced reactions of halogenated molecules. It has been two decades since the cosmic-ray (CR) driven electron-induced reaction (CRE) mechanism for the ozone hole formation was proposed. The derived CRE equation with stratospheric equivalent chlorine level and CR intensity as only two variables has well reproduced the observed data of stratospheric O3 and temperatures over the past 40 years. The CRE predictions of 11-year cyclic variations of the Antarctic O3 hole and associated stratospheric cooling have also been well confirmed. Measured altitude profiles of ozone and temperatures in Antarctic ozone holes provide convincing fingerprints of the CRE mechanism. A quantitative estimate indicates that the CRE-produced Cl atoms could completely deplete or even over-kill ozone in the CR-peak polar stratospheric region, consistent with observed altitude profiles of severest Antarctic ozone holes. After removing the natural CR effect, the hidden recovery in the Antarctic O3 hole since around 1995 is clearly discovered, while the recovery of O3 loss at mid-latitudes is being delayed by >=10 years. These results have provided strong evidence of the CRE mechanism. If the CR intensity keeps the current rising trend, the Antarctic O3 hole will return to the 1980 level by around 2060, while the returning of the O3 layer at mid-latitudes to the 1980 level will largely be delayed or will not even occur by the end of this century. The results strongly indicate that the CRE mechanism must be considered as a key factor in evaluating the O3 hole.

description: Inflammation is associated with multiple life-threatening conditions. Desmidorchis flava is an edible plant and traditionally used for managing various diseases. Three novel molecules, namely desmiflavaside-C (1), nizwaside (2), and desmiflanoside (3) were isolated from Desmidorchis flava, and their structures were confirmed by mass spectrometry and through reported literature. These compounds were in vivo examined for antinociceptive (tonic visceral nociception) and anti-inflammatory (carrageenan induced paw edema) activities. Significant antinociceptive potential was demonstrated by compound 1 at 0.5 and 1 mg/kg doses followed by compounds 2 and 3. At similar doses, significant anti-inflammatory activity was noted for all the tested compounds. Their antinociceptive and anti-inflammatory activities were comparable to the reference standards. In silico predicted binding modes suggests that these compounds may target allosteric sites of COX-1 and COX-2 enzymes to elicit their anti-inflammatory activities. These isolated natural products may have therapeutic potential in conditions afflicted with pain and inflammation.
Chinese women's perspectives on the transitional process of caring for spouses with dementia from home to institution
Creators: name: Choi, Alice Kit Ming
Publisher: name: University of British Columbia
Year: 2008

description: This study describes the caregiving experience of elderly Chinese wives while caring for their spouses with dementia at home and in an institution. Conflict arises between health care workers and family caregivers because of a different perception about role expectations. A good understanding of how the Chinese wives conceptualize their caregiving role and assign meanings to the caregiving relationship in different contexts will enable the nurses to engage ineffective care planning for the Chinese patients with dementia. Phenomenology was the research design chosen for this study because of its unique focus on revealing the participant's perception about a particular situation or experience. Data were collected through ten interviews with six Chinese women between the ages of 70 - 82 years. These women had cared for their spouses with dementia at home from one and one-half to three and one-half years before their spouses' admission to a care home. A reflective data analysis process resulted in a consistent description of the cargiving [sic] experience of the Chinese wives. An emotional experience, a sense of conflict, of the Chinese wives throughout the caregiving process, was identified as the predominant theme. The major conclusions from the findings of this study are: (1) the Chinese women perceived their caregiving role and ascribed meanings to the caregiving process quite differently from that reported in the literature, (2) the context in which caregiving is embedded has to be critically examined in order to understand how caregivers conceptualise their caregiving role. The ascribed meanings to caregiving and its significance to the caregiving relationship have to be explored as they influence role conceptualization, and (3) the Chinese culture and the traditional values held by the Chinese women were major forces in creating the situations of conflict.

description: The hyperdeteminants considered here are the simplest analogues of determinants for higher rank tensors which have been defined by Cayley, and apply only to tensors with an even number of indices. We have shown in a previous article that the calculation of certain multidimensional integrals could be reduced to the evaluation of hyperdeterminants of Hankel type. Here, we carry out this computation by purely algebraic means in the cases of Selberg's and Aomoto's integrals.

description: Έχουμε την τέχνη για να μη μας σκοτώσει η αλήθεια», είπε ο Φ. Νίτσε. Με μια πρώτη ανάγνωση, ο σκοπός της τέχνης μοιάζει να περιορίζεται στον αισθητικό, σχεδόν μεταφυσικό, εξωραϊσμό της ανθρώπινης δυστυχίας‧ η τέχνη, όμως, δεν είναι μόνο αυτό. Δε διακοσμεί την ασχήμια‧ συνδιαλέγεται μαζί της και την προκαλεί, την ανακατασκευάζει, δοκιμάζοντας τα όρια της κοινωνίας, της ηθικής και της ίδιας της δημοκρατίας. Γι’ αυτό και η θεμελίωση της καλλιτεχνικής έκφρασης ως ειδικού ατομικού δικαιώματος, καταδικασμένη να υποκύπτει σε συμβιβασμούς και περιορισμούς, υποσκάπτει την πολυεπίπεδη αποστολή της τέχνης. Η αυθαίρετη καθολίκευση των αισθητικών κρίσεων και η ηθική και δικαιική νομιμοποίηση της αισθητικής κουλτούρας της κυρίαρχης τάξης αναιρεί την ουσία της τέχνης, που δεν είναι απλώς η ψυχαγωγία του καλλιτέχνη ή του κοινού, αλλά ο κοινωνικός και ατομικός μετασχηματισμός μέσα από την καλλιτεχνική έκφραση και την πολιτισμική παιδεία. Στην παρούσα εργασία, λοιπόν, αντικείμενο μελέτης αποτελεί η τέχνη ως φαινόμενο της αισθητικής, του νομικού και του κοινωνικού κόσμου, μέσα από την εξερεύνηση των πολλαπλών διαστάσεών της για την ανθρώπινη ύπαρξη και την κοινωνική πραγματικότητα
description: F. Nietzsche said: “We have art in order not to die of the truth”. On a first read, the purpose of art appears to be merely the aesthetic, perhaps metaphysical, beautification of human misery; art, however is not confined to that limit. It does not decorate ugliness; it converses with it and reconstructs its meaning, by challenging society’s limits, its ethics and democracy. Having said that, enshrining the artistic expression in our constitution as a special right of producing art undermines the manifold purpose of art. The arbitrary universalization of aesthetic judgements and the moral and legal legitimation of the aesthetic culture of the ruling class negate the essence of art, which is not merely the entertainment of the artist or the public, but the social and individual transformation that occurs through artistic expression and cultural education. In the present paper, therefore, the subject of our study is art as a phenomenon of the aesthetics, the legal and the social world, regarding its multiple aspects that are beneficiary for human existence and social reality

description: Lexically constrained machine translation allows the user to manipulate the output sentence by enforcing the presence or absence of certain words and phrases. Although current approaches can enforce terms to appear in the translation, they often struggle to make the constraint word form agree with the rest of the generated output. Our manual analysis shows that 46% of the errors in the output of a baseline constrained model for English to Czech translation are related to agreement. We investigate mechanisms to allow neural machine translation to infer the correct word inflection given lemmatized constraints. In particular, we focus on methods based on training the model with constraints provided as part of the input sequence. Our experiments on the English-Czech language pair show that this approach improves the translation of constrained terms in both automatic and manual evaluation by reducing errors in agreement. Our approach thus eliminates inflection errors, without introducing new errors or decreasing the overall quality of the translation.

description: The purpose of this thesis is to study the legislative framework of the phenomenon of human trafficking at an international, European, EU and national level. In particular, the content of human trafficking is defined in the light of both international and EU texts as well as national law, highlighting at the same time the obligations of States to combat the phenomenon. Subsequently, we refer to the recent legislative changes by Law 4619/2019 and a detailed analysis of Article 323A of the Penal Code, which standardises human trafficking, is attempted. Finally, the legislative framework for the assistance of human trafficking victims and the issues arising from this framework are presented

description: The effective permittivity dyadic of a composite material containing particulate constituent materials with one constituent having the ability to display the Pockels effect is computed, using an extended version of the strong-permittivity-fluctuation theory which takes account of both the distributional statistics of the constituent particles and their sizes. Scattering loss, thereby incorporated in the effective electromagnetic response of the homogenized composite material, is significantly affected by the application of a low-frequency (dc) electric field.

description: In the last decades, the media effect on the issues of domestic violence and violence against women has been thoroughly examined and there is abundant literature covering the phenomenon but very little investigation has been devoted to examine the portrayal of femicide in the news coverage in European countries and more specifically, in Greece. The present study will examine the Greek media news coverage on femicide, examining the crime news stories regarding the language used in the articles, the description of both victim and perpetrator and the sources of the journalists. This investigation is based on the theoretical approach of communication gender theories exploring the representation of women in the media over the years and the relation of both genders in the news. The findings of the research are explained through the feminist theories approach to identify whether violence against women and its fatal stage, femicide, are regarded as social problem in the Greek society. Implications of the findings and future research are being discussed.

description: We have studied the hadronic interaction for the calculation of the atmospheric neutrino flux by summarizing the accurately measured atmospheric muon flux data and comparing with simulations. We find the atmospheric muon and neutrino fluxes respond to errors in the $π$-production of the hadronic interaction similarly, and compare the atmospheric muon flux calculated using the HKKM04 code with experimental measurements. The $μ^++μ^-$ data show good agreement in the 1$\sim$30 GeV/c range, but a large disagreement above 30 GeV/c. The the $μ^+/μ^-$ ratio shows sizable differences at lower and higher momenta for opposite directions. As the disagreements are considered to be due to assumptions in the hadronic interaction model, we try to improve it phenomenologically based on the quark parton model. The improved interaction model reproduces the observed muon flux data well. The calculation of the atmospheric neutrino flux will be reported in the following paper
Multigrid and saddle-point preconditioners for unfitted finite element modelling of inclusions

description: In this work, we consider the modeling of inclusions in the material using an unfitted finite element method. In the unfitted methods, structured background meshes are used and only the underlying finite element space is modified to incorporate the discontinuities, such as inclusions. Hence, the unfitted methods provide a more flexible framework for modeling the materials with multiple inclusions. We employ the method of Lagrange multipliers for enforcing the interface conditions between the inclusions and matrix, this gives rise to the linear system of equations of saddle point type. We utilize the Uzawa method for solving the saddle point system and propose preconditioning strategies for primal and dual systems. For the dual systems, we review and compare the preconditioning strategies that are developed for FETI and SIMPLE methods. While for the primal system, we employ a tailored multigrid method specifically developed for the unfitted meshes. Lastly, the comparison between the proposed preconditioners is made through several numerical experiments.

description: Gliomas, the most devastating of brain tumours, pose immense therapeutic challenges due to the adverse effects of standard chemotherapeutic drugs. Seeking alternatives, natural products have emerged as promising sources for cancer treatment. Vitex negundo, a significant medicinal plant in traditional medicine, offers potential remedies for various ailments. In this study, fractionation via column chromatography we isolated fraction #25 from leaves of Vitex negundo. Employing 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, wound healing assay, flow cytometry for cell cycle analysis, and HRLC-MS for compound identification, we investigated its effects on glioma cells. Results indicate that fraction #25 significantly reduces glioma cell viability and proliferation, inhibits cell migration in a dose-dependent manner, and arrests the cell cycle at G1 phase. Compound analysis reveals the presence of potent antiproliferative agents, including 7-hydroxy-3,4,5,6,8-pentamethoxyflavone, Virol-B, Momordin Ia, and Oryzalexin A. These findings underscore the potential of Vitex negundo as a source of anticancer compounds against glioma cells.

description: We demonstrate a hierarchy of various classes of quantum correlations on experimentally prepared two-qubit Werner-like states with controllable white noise. Werner states, which are white-noise-affected Bell states, are prototypal examples for studying such a hierarchy as a function of the amount of white noise. We experimentally generated Werner states and their generalizations, i.e., partially entangled pure states affected by white noise. These states enabled us to study the hierarchy of the following classes of correlations: separability, entanglement, steering in three- and two-measurement scenarios, and Bell nonlocality. We show that the generalized Werner states (GWSs) reveal fundamentally different aspects of the hierarchy compared to the Werner states. In particular, we find five different parameter regimes of the GWSs, including those steerable in a two-measurement scenario but not violating Bell inequalities. This regime cannot be observed for the usual Werner states. Furthermore, we find threshold curves separating different regimes of the quantum correlations and find the optimal states which allow for the largest amount of white noise, which does not destroy their specific quantum correlations (e.g., unsteerable entanglement). Thus, we could identify the optimal Bell-nondiagonal GWSs, which are, for this specific meaning, more robust against white noise compared to the Bell-diagonal GWSs (i.e., Werner states).

Μιλάμε για τους Αμερικανούς John Rawls και Ronald Dworkin, οι οποίοι στα έργα τους αφιέρωσαν εκτενείς αναλύσεις για αυτές τις δύο (2) έννοιες, ακολουθώντας σε πολλά σημεία την αρχική σκέψη και τοποθέτηση του Αριστοτέλη και σε άλλα διαφοροποιώντας παντελώς την τοποθέτησή τους. Ο John Rawls διατύπωσε στο έργο του «Η θεωρία της Δικαιοσύνης» μία θεωρία για τη συνεργασία των μελών κάθε κοινωνίας, η οποία στοχεύει στην επίτευξη της ευημερίας, και η οποία οφείλει να στηρίζεται στις αρχές της δικαιοσύνης, όπως εκείνος τις ορίζει. Από την άλλη πλευρά, ο Ronald Dworkin ασχολήθηκε με την έννοια της ισότητας, την οποία και συνέδεσε με την δικαιοσύνη και με την ελευθερία. Μιλάει συγκεκριμένα για μία δικαιοσύνη διανεμητική, μέσω της οποίας ο άνθρωπος κατορθώνει να κατακτήσει την ευημερία και την ευτυχία του. Επιπλέον, χαρακτηριστικό σημείο της θεωρίας του είναι η απόλυτη μη ταύτιση της ευτυχίας με τους πόρους, ήτοι με τα χρήματα. Το ζήτημα με το οποίο θα ασχοληθούμε στην παρούσα εργασία είναι η συσχέτιση των δύο αυτών εννοιών με τη διοίκηση, δημόσια ή ιδιωτική. Με τον όρο διοίκηση αναφερόμαστε στις ενέργειες που πραγματοποιούνται προκειμένoυ να συντονιστεί η λειτουργία ενός οργανισμού ή ενός φορέα, καθώς και η επίβλεψή τους
description: The purpose of this paper is to present in detail the views for the justice and equality of two great and most prestigious political philosophers. We talk about Americans John Rawls and Ronald Dworkin, who in their works devoted extensive analyzes of these two (2) concepts, following in many aspects the original thinking and attitude of Aristotle and in others, completely differentiating their attitude. John Rawls has formulated in his work «The Theory of Justice» a theory of cooperation of members of every society, which aims at the attainment of prosperity, and which must be based on the principles of justice as he defines them. On the other hand, Ronald Dworkin dealt with the notion of equality, which he linked to justice and freedom. He speaks specifically of a distributive justice, through which, man succeeds in conquering his prosperity and happiness. Moreover, the hallmark of his theory is the absolute non-identification of happiness with resources, that is, with money. The issue that we will deal with in this paper is to relate these two concepts to management, public or private. By management we mean the actions taken to coordinate the functioning of an organization or body and to supervise them

description: In Europe, is still a reality today the separation of students with disabilities. Its negative consequences are particularly affecting children with disabilities because of their social or personal situation. The purpose of the present study is to investigate the attitudes and beliefs of parents of kindergarten students with typical development regarding inclusive education and in particular educational inclusion of autistic children. This study examined the views and attitudes of parents of typical developmental students in the social and educational dimensions in preschool education settings. For this reason, one hundred ninety-five questionnaires developed. The results of the analysis showed that there are positive indications for acceptance of inclusive practices.

description: A simplified version of a classical problem in thermodynamics -- the adiabatic piston -- is discussed in the framework of kinetic theory. We consider the limit of gases whose relaxation time is extremely fast so that the gases contained on the left and right chambers of the piston are always in equilibrium (that is the molecules are uniformly distributed and their velocities obey the Maxwell-Boltzmann distribution) after any collision with the piston. Then by using kinetic theory we derive the collision statistics from which we obtain a set of ordinary differential equations for the evolution of the macroscopic observables (namely the piston average velocity and position, the velocity variance and the temperatures of the two compartments). The dynamics of these equations is compared with simulations of an ideal gas and a microscopic model of gas settled to verify the assumptions used in the derivation. We show that the equations predict an evolution for the macroscopic variables which catches the basic features of the problem. The results here presented recover those derived, using a different approach, by Gruber, Pache and Lesne in J. Stat. Phys. 108, 669 (2002) and 112, 1177 (2003).

In this paper, we present a \emph{hierarchical-forecasting-with-alignment} approach that treats the bottom level forecasts as mutable to ensure higher forecasting accuracy on the upper levels of the hierarchy. We employ a pure deep learning forecasting approach N-BEATS for continuous time series at the top levels and a widely used tree-based algorithm LightGBM for the intermittent time series at the bottom level. The \emph{hierarchical-forecasting-with-alignment} approach is a simple yet effective variant of the bottom-up method, accounting for biases that are difficult to observe at the bottom level. It allows suboptimal forecasts at the lower level to retain a higher overall performance. The approach in this empirical study was developed by the first author during the M5 Forecasting Accuracy competition, ranking second place. The method is also business orientated and could benefit for business strategic planning.

description: We investigate the magnetic properties of a Heisenberg ferrimagnetic multilayer by using Monte Carlo simulations. The aim of this work is to study the local structural anisotropy model which is a possible origin of the perpendicular magnetic anisotropy in transition metal/rare earth amorphous multilayers. We have considered a face centered cubic lattice where each site is occupied by a classical Heisenberg spin. We have introduced in our model of amorphous multilayers a small fraction of crystallized Fe-Dy nanoclusters with a mean anisotropy axis along the deposition direction. We show that a competition in the energy terms takes place between the mean uniaxial anisotropy of the Dy atoms in the nanoclusters and the random anisotropy of the Dy atoms in the matrix.

Control of land-based marine pollution in Southeast Asia : a legal perspective
Creators: name: Cai, Tong
Publisher: name: University of British Columbia
Year: 2008

description: Marine pollution from land-based sources is a new and challenging topic in international law development. Since the subject matter of land-based marine pollution is very complex in social-economic and scientific terms, the implementation of the newly developed rules of international law on land-based marine pollution would seem to vary from region to region, depending on the specific capabilities of different region. The marine environment in Southeast Asia, where there is a considerable base for land-based marine pollution, is experiencing a serious degradation from this kind of pollution. The developing countries in Southeast Asia have started to provide provisions concerning the control of land-based marine pollution in their respective legislation in either a general or a specific way. However, due to the various reasons, the current efforts on the control of land-based marine pollution from the legal aspect by these countries are far from sufficient. Many of the problems at earlier stages of development can be solved by learning experience which advanced countries have foregone in the past. As regards to land-based marine pollution control, effective legal efforts have been made by the Baltic states, the United States, and Japan. The Southeast Asia countries may borrow the appropriate ideas, methods, and operational systems worked out by these countries with suitable modification and adaptation in consonance with local customs, tradition, and social-economic peculiarities. There is considerable potential capability in the countries of Southeast Asia of forming legislative framework and establishing effective enforcement strategy for land-based marine pollution control. On the other hand, in Southeast Asia where there is a highly complex social-economic construction, the contraversies between nationalism and regionalism appear to be the major obstacles in terms of effective legal control on land-based marine pollution. Further efforts should be made to achieve a concerted regional approach as well as conresponding [sic] national commitments in the protection and preservation of the marine environment in Southeast Asia against pollution from land-based sources.

description: Τα τελευταία χρόνια ένας νέος όρος εμφανίζεται στον τομέα της εφοδιαστικής και της διαχείρισής της ενώ πολλά ανεπίσημα άρθρα προσπαθούν να προσεγγίσουν αυτό το ζήτημα από διαφορετικές οπτικές. Πιο συγκεκριμένα, υπάρχει μεγάλη ανησυχία για την έννοια της ελαστικής εφοδιαστικής, η οποία αναφέρεται ως η ικανότητα μιας εταιρείας να επεκτείνει ή να συρρικνώσει τις δυνατότητες της εφοδιαστικής, προκειμένου να καλύψει την επερχόμενη ζήτηση και τις διακυμάνσεις της. Με άλλα λόγια, αυτό το μοντέλο επικεντρώνεται στον τρόπο με τον οποίο οι οργανισμοί θα μπορούσαν να προετοιμάσουν τις λειτουργίες της εφοδιαστικής αλυσίδας, προκειμένου να αντιμετωπίσουν τις τάσεις, τις προτιμήσεις των καταναλωτών και γενικά το μεταβαλλόμενο περιβάλλον της αγοράς.

Βασισμένο σε ένα ευρύ φάσμα ορισμών, η έρευνας στοχεύει να εξετάσει αυτό το μοντέλο από την πλευρά του πελάτη και να προτείνει ένα πλαίσιο εφαρμογής. Δεδομένου ότι δύο από τα κεντρικά σημεία αυτού του ορισμού είναι οι πελάτες και η μελλοντική ζήτηση, αυτή η διπλωματική επικεντρώνεται σε εκτεταμένη συστηματική ανάλυση δημοσιευμένων άρθρων και βιβλιογραφίας, τις πτυχές ανάλυσης πελατών, εργαλεία ανάλυσης δεδομένων και ευέλικτες στρατηγικές εφοδιαστικής αλυσίδας για την εξάλειψη του κινδύνου ώστε να επιτευχθεί μεγαλύτερος έλεγχος. Καθώς είναι σημαντικό να κατανοήσουμε τις ρίζες αυτού του μοντέλου, η εργασία αναλύει ένα πραγαμτικό σενάριο μιας ελληνικής εταιρείας στον κλάδο των καταναλωτικών αγαθών, όπου αναλύονται δεδομένα πελατών, αναπτύσσονται μέθοδοι πρόβλεψης και εύρεσης βέλτιστης τοποθεσίας. Το πρόβλημα αυτο επικεντρώνεται στην αξιολόγηση περιοχών προκειμένου η εν λόγω εταιρία να αποθηκεύσει προϊόντα κατά την προσεχή περίοδο του καλοκαιριού (2020) και να εξυπηρετήσει αποτελσματικότερα τους πελάτες της.

description: We propose a novel sparsity model for distributed compressed sensing in the multiple measurement vectors (MMV) setting. Our model extends the concept of row-sparsity to allow more general types of structured sparsity arising in a variety of applications like, e.g., seismic exploration and non-destructive testing. To reconstruct structured data from observed measurements, we derive a non-convex but well-conditioned LASSO-type functional. By exploiting the convex-concave geometry of the functional, we design a projected gradient descent algorithm and show its effectiveness in extensive numerical simulations, both on toy and real data.

Failure of feedback as a putative common mechanism of spreading depolarizations in migraine and stroke

description: The stability of cortical function depends critically on proper regulation. Under conditions of migraine and stroke a breakdown of transmembrane chemical gradients can spread through cortical tissue. A concomitant component of this emergent spatio-temporal pattern is a depolarization of cells detected as slow voltage variations. The velocity of ~3 mm/min indicates a contribution of diffusion. We propose a mechanism for spreading depolarizations (SD) that rests upon a nonlocal or non-instantaneous feedback in a reaction-diffusion system. Depending upon the characteristic space and time scales of the feedback, the propagation of cortical SD can be suppressed by shifting the bifurcation line, which separates the parameter regime of pulse propagation from the regime where a local disturbance dies out. The optimisation of this feedback is elaborated for different control schemes and ranges of control parameters.

description: Young's lattice is a prototypical example of differential posets. Differential posets have the Robinson correspondence, the correspondence between permutations and pairs of standard tableaux with the same shape, as in the case of Young's lattice. Fomin introduced generalized Schur operators to generalize the method of Robinson correspondence in differential posets to the Robinson-Schensted-Knuth correspondence, the correspondence between certain matrices and pairs of semi-standard tableaux with the same shape. In this paper, we introduce operators on the vector space whose basis is the set of planar binary trees. To prove that the operators are generalized Schur operators, we construct a correspondence, which is an extension of Fomin's r-correspondence for them.
Possible dimensionality transition behavior in localized plasmon resonances of confinement-controlled graphene devices

description: We investigated the dimensionality transition behavior of graphene localized plasmon resonances in confinement-controlled graphene devices. We first demonstrated a possibility of dimensionality transition, based on the devices carrier-density dependence, from a two-dimensional plasmon resonance to a one-dimensional plasmon one. We fabricated optical transparent devices and electrical transport devices on the same optical transparent wafer. These devices allow detailed control and analysis between carrier density and plasmon resonance peak positions. The carrier density from square root n (two-dimensional) to constant (one-dimensional) is consistent with the theoretical predictions based on the Dirac Fermion carriers in linear-band structure materials.

description: The time evolution of spin states of two electrons interacting with a nuclear spin bath in a quantum dot system is studied. The hyperfine interaction between the electrons and the nuclear spins is modeled by an isotropic Heisenberg interaction, and the interaction between the electron spins by Heisenberg exchange. Depending on the extent of the overlap between the spatial wave functions of the electrons, there are two physically different cases, namely the two qubits either interact with the same set of nuclear spins or they see different nuclear spin environment. In the two cases, the decoherence of the two-qubit state is studied analytically. We have identified a class of two-qubit states which have a rich dynamics when the exchange interaction between the qubits becomes large in comparison to the hyperfine interaction strengths. The decoherence time scale is determined as a function of the bath-spin distribution and the polarizations of the initial two-qubit state. States with large decoherence times are identified by performing a minimization over all the two-qubit pure states.

description: In this paper, we apply the long short-term memory (LSTM), an advanced recurrent neural network based machine learning (ML) technique, to the problem of transmitter selection (TS) for secrecy in an underlay small-cell cognitive radio network with unreliable backhaul connections. The cognitive communication scenario under consideration has a secondary small-cell network that shares the same spectrum of the primary network with an agreement to always maintain a desired outage probability constraint in the primary network. Due to the interference from the secondary transmitter common to all primary transmissions, the secrecy rates for the different transmitters are correlated. LSTM exploits this correlation and matches the performance of the conventional technique when the number of transmitters is small. As the number grows, the performance degrades in the same manner as other ML techniques such as support vector machine, $k$-nearest neighbors, naive Bayes, and deep neural network. However, LSTM still significantly outperforms these techniques in misclassification ratio and secrecy outage probability. It also reduces the feedback overhead against conventional TS.
