description: The present research investigates the official classification systems in order to find common, important sectors and criteria. Some criteria indicate the perception of certifying organizations, of countries that apply them, and of the hotel industry, as to what is important for a hotel to offer. Official classification systems state their basic principles, which differ from one system to another and not all are met at the same time. Most countries give three reasons for entering a formal rating system: consumer protection, tourism planning and marketing. The study will present the practices applied in the hotel industry, through compliance with official classification systems. It will contribute to the existing knowledge of hoteliers, institutions and organizations that create hotel certification systems, and in general to the knowledge of the tourism industry. Hotel classification systems are tools for maintaining the high quality of hotel industry. Also, τhe classification of hotels presents heterogeneity. Common points are the range of ranking categories and the marks used, but if the requirements of the criteria of each category are analyzed, very different conditions are discovered, sometimes even within the same country. Nevertheless, the introduction of a classification system for hotels is a complex matter due to the diversity of classification systems, accommodation types and the cultural, environmental and economic context in which the systems operate each time in individual countries. This study results, in a proposed model hotel classification system, which will directly contribute to reducing the risk of not meeting customers' expectations and providing hotel services more efficiently, depending on the type and category of accommodation. Effective management of customer expectations is crucial to ensuring the viability of the tourism business. The survey data were drawn from the analytical recording and processing of 39 classification systems, applied in different countries and continents.

description: We study spectral properties of the Fokker-Planck operator that represents particles moving via a combination of diffusion and advection in a time-independent random velocity field, presenting in detail work outlined elsewhere [J. T. Chalker and Z. J. Wang, Phys. Rev. Lett. {\bf 79}, 1797 (1997)]. We calculate analytically the ensemble-averaged one-particle Green function and the eigenvalue density for this Fokker-Planck operator, using a diagrammatic expansion developed for resolvents of non-Hermitian random operators, together with a mean-field approximation (the self-consistent Born approximation) which is well-controlled in the weak-disorder regime for dimension d>2. The eigenvalue density in the complex plane is non-zero within a wedge that encloses the negative real axis. Particle motion is diffusive at long times, but for short times we find a novel time-dependence of the mean-square displacement, $ \sim t^{2/d}$ in dimension d>2, associated with the imaginary parts of eigenvalues.

description: Magnetic skyrmions in bulk crystals are line-like topologically protected spin textures. They allow for the propagation of magnons along the skyrmion line but are localized inside the skyrmion line. Analogous to the vortex line, these propagating modes are the Kelvin modes of a skyrmion line. In crystals without an inversion center, it is known that the magnon dispersion in the ferromagnetic state is asymmetric in the wavevector. It is natural to expect that the dispersion of the Kelvin modes is also asymmetric with respect to the wavevector. We study the Kelvin modes of a skyrmion line in the ferromagnetic background. In contrast, we find that the lowest Kelvin mode is symmetric in the wavevector in the low energy region despite the inversion symmetry breaking. Other Kelvin modes below the magnon continuum are asymmetric, and most of them have a positive group velocity. Our results suggest that a skyrmion line can function as a one-way waveguide for magnons.

description: ICAMPAM 2021 Poster presentation: Quantifying activity to study healthy ageing landscape While, nowadays, people generally live longer, they are increasingly facing health issues, leading to a reduction in functionality and quality of life along with an increase in medical costs. Sedentary lifestyles among the elderly mount to 10 hrs inactivity per day. Hence combined caloric intake/physical activity interventions are applied to encourage the elderly to follow a more active and healthy lifestyle. These need to be carefully monitored. The Growing Old TOgether (GOTO) study introduces such an intervention, where a 13-weeks lifestyle program was applied, with a target of 12.5% caloric restriction and 12.5% increase in energy expenditure through an increase in physical activity, in 164 older adults (mean age=63.2 years; BMI=23-35 kg/m2). Quantifying the changes in physical behaviour is of utmost importance in order to investigate their effect on health gains. Using data from wrist and ankle activity accelerometers (wearables) and machine learning models, we were able to recognize the different activities performed and to report their frequencies and durations both in baseline and after the 13-weeks intervention. To quantify these observations, we built activity profiles that we intend to associate with changes in physiological parameters of health.

description: Periodically driven quantum many-body systems support anomalous topological phases of matter, which cannot be realized by static systems. In many cases, these anomalous phases can be many-body localized, which implies that they are stable and do not heat up as a result of the driving. What types of anomalous topological phenomena can be stabilized in driven systems, and in particular, can an anomalous phase exhibiting non-Abelian anyons be stabilized? We address this question using an exactly solvable, stroboscopically driven 2D Kitaev spin model, in which anisotropic exchange couplings are boosted at consecutive time intervals. The model shows a rich phase diagram which contains anomalous topological phases. We characterize these phases using weak and strong scattering-matrix invariants defined for the fermionic degrees of freedom. Of particular importance is an anomalous phase whose zero flux sector exhibits fermionic bands with zero Chern numbers, while a vortex binds a pair of Majorana modes, which as we show support non-Abelian braiding statistics. We further show that upon adding disorder, the zero flux sector of the model becomes localized. However, the model does not remain localized for a finite density of vortices. Hybridization of Majorana modes bound to vortices form "vortex bands", which delocalize by either forming Chern bands or a thermal metal phase. We conclude that while the model cannot be many-body localized, it may still exhibit long thermalization times, owing to the necessity to create a finite density of vortices for delocalization to occur.

Characteristics of Community Radio: An Entertainment Factory or Catalyst for Development, Food and Nutrition Security

description: Several studies have confirmed that Community Radio can go a long way in promoting agriculture by educating farmers about new farming methods; issuing early warning whenever there are outbreaks of pests and diseases; monitoring weather patterns and informing farmers on appropriate planting dates. Further research argues that communication of science and technology best occurs outside the school through real world experiences with the media as an important forum at which such experiences are shared. Most rural folk rely on CR as a source of news and entertainment. However, CR is much more than an entertainment factory; it is potentially an invaluable forum for rural farmers and agricultural researchers to engage in scientific dialogue, which is aimed at achieving the Sustainable Development Goal (SGD) number 2. This paper, therefore, investigates the extent to which efforts have been made to unlock CR’s potential in working towards attaining the national goal of ending hunger, achieving food security, improving nutrition and promoting sustainable agriculture. The paper will rely on survey data drawn from a recent study on the link between Community Radio and Food Security. Findings of this study indicate that Community Radio could offer a lasting solution to the challenge of rural development, especially food and nutrition security. The outcome is expected to inform policy on the need to enhance integration of CR in disseminating agricultural information to rural farmers in Kenya as the country marches towards the successful implementation of its national development goal of making Kenya a Food Secure nation.

The Lie-algebraic procedure of discretization of differential equations with isospectral property is proposed. Using $sl_2$-algebra based approach, (quasi)-exactly-solvable finite-difference equations are described. It is shown that the operators having the Hahn, Charlier and Meixner polynomials as the eigenfunctions are reproduced in present approach as some particular cases. A discrete version of the classical orthogonal polynomials (like Hermite, Laguerre, Legendre and Jacobi ones) is introduced.

description: Η αντίθεση του Mikhail Bakhtin προς τις πάσης φύσεως διχοτομίες που χαρακτηρίζουν τη θεωρία του Ferdinand de Sanssure (ομιλία - γλώσσα, συγχρονία - διαχρονία) αποτελεί την αφετηρία της κριτικής του, η οποία με ένα συστηματικό και εξαιρετικά διαυγή τρόπο προχωρεί στην απόρριψή τους ως ακραίων παραδειγμάτων ορθολογιστικού δυαδισμού. Κατά τη γνώμη του εισηγητή, οι γλωσσολογικές θέσεις που αναπτύσσονται στο βιβλίο του Valentin Volosinov Marxism and the Philosophy of Language τροφοδοτούν αδιαλείπτως τη σκέψη του Bakhtin, όταν επιχειρεί τη συγγραφή του κορυφαίου έργου του Problems of Dostoevsky's Poetics, όπου η πολυφωνία και η διαλογικότητα της λογοτεχνίας του Ρώσου μυθιστοριογράφου αναδεικνύονται σε κυρίαρχα χαρακτηριστικά.

Kinematic Enhancement of Non-Perturbative Corrections to Quarkonium Production

Year: 1997

description: In this letter we address issues involved in quarkonium production near the boundaries of phase space. It is shown that higher-order non-perturbative contributions are enhanced in this kinematic region and lead to a breakdown of the non-relativistic (NRQCD) expansion. This breakdown is a consequence of sensitivity to the kinematics of soft gluon radiation and to the difference between partonic and hadronic phase space. We show how these large corrections can be resummed giving the dominant contribution to the cross section. The resummation leads to the introduction of non-perturbative, universal distribution functions. We discuss the importance of these shape functions for several observables, in particular the energy distribution of photo-produced $J/ψ$ close to the endpoint.

Oxford. 1958. and β) The Oxford English Dictionary (O.E.D.). 2nd edition. Oxford. 1989. The words were traced in the first one, and their Greek origin was confirmed in the second one. Shakespeare used 197 words of common sense and 115 proper names. Words that diverge semantically are especially pointed out, as well as words that have been formed out of proper names, and have the place of words of common sense in the Shakespeare's works. The process that the words have gone through is also traced: The French route after the Norman Conquest (1.066) or the Vatican bridge much earlier? It is clear that Shakespeare knew the Ancient Greek Literature. Taking this fact in consideration, we can explain the miracle of his literary output.

Production of K^0_S and Lambda in Quark and Gluon Jets from Z^0 Decay

Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: The production of K^0_S mesons and Lambda baryons in quark and gluon jets has been investigated using two complementary techniques. In the first approach, which provides high statistical accuracy, jets were selected using different jet finding algorithms and ordered according to their energy. Production rates were determined taking into account the dependences of quark and gluon compositions as a function of jet energy as predicted by Monte Carlo models. Selecting three-jet events with the k_perp (Durham) jet finder (y_cut = 0.005), the ratios of K^0_S and Lambda production rates in gluon and quark jets relative to the mean charged particle multiplicity were found to be 1.10 +/- 0.02 +/- 0.02 and 1.41 +/- 0.04 +/- 0.04, respectively, where the first uncertainty is statistical and the second is systematic. In the second approach, a new method of identifying quark jets based on the collimation of energy flow around the jet axis is introduced and was used to anti-tag gluon jets in symmetric (Y-shaped) three-jet events. Using the cone jet finding algorithm with a cone size of 30 degrees, the ratios of relative production rates in gluon and quark jets were determined to be 0.94 +/- 0.07 +/- 0.07 for K^0_S and 1.18 +/- 0.10 +/- 0.17 for Lambda. The results of both analyses are compared to the predictions of Monte Carlo models.

description: We investigate the convergence of the derivative expansion of the exact renormalization group, by using it to compute the beta function of scalar field theory. We show that the derivative expansion of the Polchinski flow equation converges at one loop for certain fast falling smooth cutoffs. The derivative expansion of the Legendre flow equation trivially converges at one loop, but also at two loops: slowly with sharp cutoff (as a momentum-scale expansion), and rapidly in the case of a smooth exponential cutoff. Finally, we show that the two loop contributions to certain higher derivative operators (not involved in beta) have divergent momentum-scale expansions for sharp cutoff, but the smooth exponential cutoff gives convergent derivative expansions for all such operators with any number of derivatives.

description: We present an algorithm which allows to solve analytically linear systems of differential equations which factorize to first order. The solution is given in terms of iterated integrals over an alphabet where its structure is implied by the coefficient matrix of the differential equations. These systems appear in a large variety of higher order calculations in perturbative Quantum Field Theories. We apply this method to calculate the master integrals of the three--loop massive form factors for different currents, as an illustration, and present the results for the vector form factors in detail. Here the solution space emerging is given by the cyclotomic harmonic polylogarithms and their associated special constants. No special basis representation of the master integrals is needed. The algorithm can be applied as well to more general cases factorizing at first order, which are based on more general alphabets, iterated integrals and associated constants.

description: We describe an explicit connection between solutions to equations $Df=0$ (the Generalized Cauchy-Riemann equation) and $(D+M)f=0$, where operators $D$ and $M$ commute. The described connection allows to construct a ``function theory'' (the Cauchy theorem, the Cauchy integral, the Taylor and Laurent series etc.) for solutions of the second equation from the known function theory for solution of the first (generalized Cauchy-Riemann) equation. As well known, many physical equations related to the orthogonal group of rotations or the Lorentz group (the Dirac equation, the Maxwell equation etc.) can be naturally formulated in terms of the Clifford algebra. For them our approach gives an explicit connection between solutions with zero and non-zero mass (or external fields) and provides with a family of formulas for calculations. \keywords{Dirac equation with mass, Clifford analysis.} \AMSMSC{30G35}{34L40, 81Q05}

description: The most widely recognized definition of bioeconomy The 2030 Agenda for Sustainable Development pledged to move away from growing inequality to more inclusive, shared growth, away from ecocide, mass extinction of our plant and animal biodiversity, and waste and destruction of our planet’s abundant but still finite natural resources to practices that respect and protect our common home, and away from activities that expose hundreds of millions of people to the insidious effects of rising global temperatures and its consequences for cli- mate risks. At the heart of the 2030 Agenda was a promise to prioritize to eradicate poverty and end hunger and malnutrition in all their forms. Too many people in the world today do not have access to sufficient, affordable, safe and healthy foods. About three billion people in the world cannot afford a healthy diet.1 To address this global challenge, G7 heads of states at their Summit in Elmau in 2015 committed to lifting 500 million people out of hunger and malnutrition by 2030, i.e. 72 percent of the total undernourished in 2019 and 60 percent of the total including COVID-19 projections in 2020,2 as part of a broader effort to be undertaken with partner countries to support the 2030 Agenda for Sustainable Development, i.e. Sustainable Development Goal 2 (SDG 2) to end hunger and malnutrition by 2030 (Box 1).
Obviously, more and different investments and policy actions are needed to reach a world without hunger and malnutrition. We conceptualize ending hunger from different angles: as an important and feasible investment opportunity from a human rights perspective, as a humanitarian obligation, and for economic development. Experiences with COVID-19 and related responses from societies and political leadership tell us that significant action is possible. The hunger problem can be solved and deserves such action. The UN Secretary General’s Food Systems Summit, and reform and policy efforts in support of the SDGs in many regions and countries, including by the EU and Germany, offer opportunities to take related interventions forward.
This policy brief is a call to action from the research community to not only address the problems of hunger, malnutrition and poverty, but to actually act and invest and adapt policies to reach SDG 2 by 2030.

description: Time crystals are quantum systems which are able to reveal condensed matter behavior in the time domain. It is known that crystalization in time can be observed in a periodically driven many-body system when interactions between particles force a system to evolve with a period which is an integer multiple of a driving period. This phenomenon is dubbed discrete time crystal formation. Here, we consider ultra-cold atoms bouncing on an oscillating atom mirror and show that the system can spontaneously form a discrete time crystal where the ratio of a period of its motion and a driving period is a rational number. This kind of discrete time crystals requires higher order resonant driving which is analyzed here with the help of an original approach.

description: The need for clarity of processes and interoperability of administrative applications has led to the creation of ontologies about the administrative domain. However, there is a gap in terms of traceability of the concepts. Unlike other domains, governance and administration is more trusted, usable, and effective when the entities and activities can be authenticated and verified. This research introduces a formalised provenance approach to ascertain the origin of concepts such as process status, digital resources, and personnel within the administrative domain. Firstly, an existing administrative ontology is identified as a case study. Provenance points are extracted from the ontology such as process provenance, document provenance and personnel provenance. The knowledge for verifying these provenance points is outlined in plain language and then formalised using description logic. The description logics are then formatted using Web ontology language (owl). Finally, Competency questions are used to validate the provenance ontology using SPARQL query. This research is an extension of existing administrative ontologies by adding provenance, thereby increasing the level of quality and trust in administrative applications when they make use of the ontology. It also improves the level of data integrity when these administrative applications share data between each other.

description: For any resource theory it is essential to identify tasks for which resource objects offer advantage over free objects. We show that this identification can always be accomplished for resource theories of quantum measurements in which free objects form a convex subset of measurements on a given Hilbert space. To this aim we prove that every resource measurement offers advantage for some quantum state discrimination task. Moreover, we give an operational interpretation of robustness, which quantifies the minimal amount of noise that must be added to a measurement to make it free. Specifically, we show that this geometric quantity is related to the maximal relative advantage that a resource measurement offers in a class of minimal-error state discrimination problems. Finally, we apply our results to two classes of free measurements: incoherent measurements (measurements that are diagonal in the fixed basis) and separable measurements (measurements whose effects are separable operators). For both of these scenarios we find, in the asymptotic setting in which the dimension or the number of particles increase to infinity, the maximal relative advantage that resource measurements offer for state discrimination tasks.

description: In order to make access to space more affordable for both scientific and commercial activities the German Aerospace Center (DLR), the Japan Aerospace Exploration Agency (JAXA) and the French National Centre for Space Studies (CNES) joined in a trilateral agreement to develop and demonstrate key technologies for a future reusable launch vehicle. In the joint project CALLISTO (Cooperative Action Leading to Launcher Innovation in Stage Toss back Operations) a reusable vertical take-off, vertical landing rocket is developed as a demonstrator for a reusable first stage. The test flight operations will take place at the Guiana Space Centre (GSC), in French Guiana. This paper gives a textual overview of the control strategies of the DLR/JAXA guidance and control subsystem for the CALLISTO test flights. The main assumptions adopted for design and simulation will be illustrated, and an overview of the foreseen mission profiles will be given. The missions consist of multiple flight phases having different aerodynamic configurations of the vehicle: the ascent phase, the boost-back maneuvers, the aerodynamic phase, and the powered descent and landing phase. We describe the sequence of events and the high-level GC mode for each phase, including the criteria for the phase transitions as evaluated by the on-board computer. To autonomously control the vehicle during the different flight phases multiple classic and modern control methods are utilized. Finally some simulation results based on a preliminary GC design are being discussed.

description: Blue foods – fish, invertebrates, algae and aquatic plants captured or cultured in freshwater and marine ecosystems – play a central role in food and nutrition security for billions of people and are a cornerstone of the livelihoods, economies, and cultures of many coastal and riparian communities. Blue food systems are extraordinarily diverse, involving thousands of species in many different production systems and supporting a wide array of cultures and diets. Many blue foods are rich in please see back-page) bioavailable micronutrients and can be produced in ways that are more environmentally sustainable than terrestrial animal-source foods. Yet despite their unique value and interconnections with terrestrial food systems, blue foods are often left out of food system analyses, discussions, decisions, and solutions. Realizing the potential of blue foods to play a central role in ending malnutrition and in building healthy, nature-positive and resilient food systems will require that governments embed blue foods in food- system governance. Here, we focus on three central imperatives for policymakers.

description: The modern Russian agrifood industry is one of the most steadily developing sectors of the national economy. The production of several goods shows historical records. Russia has a very strong position in the world export of agricultural raw commodities and low degree processing products from one side and localizing import dependence on certain products’ groups, our country remains critically dependent on the means of their production from the other side. It is obvious that this state of affairs is not only an Achilles ' heel in ensuring national sustainability of food systems, but also hinders the growth of global competitiveness even within the current technological order. An increasingly acute problem of the Russian food systems transition to the innovative path is the reduction of human resources. This trend is typical both for the scientific sector, where it is expressed in the number of researchers decrease, an aging staff (which threatens the continuity in the established scientific schools and the viability of research teams) and for the agriculture as a whole. This report examines critical areas of scientific research in Russia, which, according to the experts who participated in its preparation, will create “windows of opportunity” for increasing competitiveness in the situation of the transition of the world food systems from conventional agriculture to Agriculture 4.0. This period is key for ensuring further economic growth in Russia.

description: Aerodynamic instability in the transonic flow regime is one of the critical problems, during atmospheric reentry phase using sample return capsule (SRC), which can cause self-excited oscillation by aerodynamic force. In this study, we numerically investigated flow fields around a Hayabusa-type SRC to clarify the mechanism of aero dynamic instability using a computational fluid dynamics (CFD) approach. Flow fields at subsonic and supersonic speeds in a transonic wind tunnel were reproduced here. The computed results indicated that an expansion region of the flow field is important to make the SRC stable.

description: An excess of events at large Q2 with a positron in the final state has been observed at HERA which, if confirmed, would be a signal of new physics. It is not clear at present if a signal of comparable rate is also seen in the charged current channel (with an antineutrino in the final state). In this note we analyse the implications of the presence of such a signal in models of new physics based on contact terms, leptoquarks and squarks with R-violating decays. We find that in all cases the most likely possibility is that the charged current signal is absent. As a consequence if this signal is present the resulting indications are very selective. In particular for squarks only charged current events with multi-quark final states are possible with quite definite predictions on the spectrum of supersymmetric particles.
