description: Η μικτή μάθηση (blended learning), μέθοδος που συνδυάζει τη δια ζώσης διδασκαλία με τη μάθηση μέσω διαδικτυακών εξ αποστάσεως δραστηριοτήτων με τη συνδρομή Τ.Π.Ε, εμφανίστηκε ως μια από τις πιο δημοφιλείς παιδαγωγικές έννοιες στις αρχές του 2000. Παλαιότερα, η έλλειψη τεχνολογικής διαθεσιμότητας απέτρεπε τον συνδυασμό της παραδοσιακής πρόσωπο με πρόσωπο (face-to-face) μάθησης με συνεργατικά περιβάλλοντα εξ αποστάσεως μάθησης. Ωστόσο, τα τελευταία 20 χρόνια η η εισαγωγή των νέων τεχνολογικών καινοτομιών γέμισε το κενό αυτό. Καθώς τα νέα μοντέλα μάθησης πολλαπλασιάζονται, ένας αυξανόμενος αριθμός μαθητών θα χρησιμοποιεί τη διαδικτυακή μάθηση ως μέρος της μαθησιακής τους πορείας (Bailey κ.ά., 2013, σελ.4). Ο Graham (2006, σελ.7) είχε δηλώσει πως η μικτή μάθηση θα παίξει μεγάλο ρόλο στο μέλλον. Οι πρόσφατες λοιπόν εξελίξεις στην τεχνολογία ενθαρρύνουν τους εκπαιδευτικούς να εφαρμόζουν τη μικτή μάθηση στις τάξεις τους, και είναι πολλοί εκείνοι που υποστηρίζουν ένθερμα τη μέθοδο αυτή. Τι συμβαίνει όμως από την πλευρά των εκπαιδευομένων; Τι σκέφτονται εκείνοι για τη νέα αυτή μέθοδο; Στην παρούσα εργασία μελετήσαμε ποιες είναι οι στάσεις και οι απόψεις των μαθητών της Α΄ τάξης Λυκείου στο πλαίσιο πραγματοποίησης μαθημάτων γαλλικής γλώσσας με τη μέθοδο του Blended Learning, και συγκεκριμένα το μοντέλο της ανεστραμμένης τάξης. Τα αποτελέσματα της έρευνας έδειξαν ότι οι περισσότεροι μαθητές είχαν θετική στάση απέναντι στη μέθοδο αυτή, και σημείωσαν ως μεγαλύτερο πλεονέκτημα της μεθόδου τη χρήση της τεχνολογίας στη μάθηση, ενώ υπήρξαν και αρνητικές εντυπώσεις, όπως η δυσκολία που υφίσταται στην πραγματοποίηση των μαθημάτων όταν δεν υπάρχει καλή η καθόλου σύνδεση στο διαδίκτυο.

description: Η ηγεσία και οι θεωρίες που αναπτύχθηκαν γύρω από αυτή, βρίσκει πρακτικό πεδίο εφαρμογής σε όλους τους οργανισμούς. Δεδομένου ότι κάθε σχολείο λογίζεται ως ένας οργανισμός, οι θεωρίες αυτές σχετίζονται άμεσα και με τον χώρο της εκπαίδευσης, ο οποίος πρέπει να ακολουθήσει τις ραγδαίες εξελίξεις και αλλαγές που συμβαίνουν στην κοινωνία που ζούμε. Στη συγκεκριμένη έρευνα, στην οποία συμμετείχαν 153 εκπαιδευτικοί πρωτοβάθμιας εκπαίδευσης, θα γίνει προσπάθεια παρουσίασης των απόψεών τους σχετικά με τα στυλ ηγεσίας που επιλέγουν να εφαρμόζουν οι διευθυντές στο σύγχρονο ελληνικό σχολείο. Τα τρία βασικά στυλ ηγεσίας που εξετάζει η έρευνα είναι το μετασχηματιστικό στυλ ηγεσίας, το συναλλακτικό και τέλος το παθητικό, ενώ γίνεται και αναφορά στην έκβαση της ηγεσίας. Επίσης, θα γίνει προσπάθειας συσχέτισης των στυλ ηγεσίας με την ανάπτυξη σχολικής κουλτούρας στον οργανισμό, καθώς έχει διαφανεί από τη βιβλιογραφία ότι η τελευταία παίζει σπουδαίο ρόλο στην άρτια λειτουργία μιας σχολικής μονάδας. Ένα άλλο θέμα που εξετάζεται στην παρούσα εργασία είναι το κομμάτι της καινοτομίας και πιο συγκεκριμένα η εφαρμογή καινοτόμων προγραμμάτων στο δημοτικό σχολείο, τόσο σε εγχώριο όσο και σε ευρωπαϊκό επίπεδο. Το τρίτο σκέλος της έρευνας είναι αυτό που εξετάζει την καινοτομία, και πιο συγκεκριμένα διερευνά το πώς το στυλ ηγεσίας που επιλέγει να εφαρμόσει ένας διευθυντής σε μια σχολική μονάδα ενισχύει την προώθηση καινοτόμων προγραμμάτων προς αυτή την κατεύθυνση.

description: Photochemical reactions often involve states that are closely coupled due to near degeneracies, for example by proximity to conical intersections. Therefore, a multistate method is used to accurately describe these states; for example, ordinary perturbation theory is replaced by quasidegenerate perturbation theory. Multiconfiguration pair-density functional theory (MC-PDFT) provides an efficient way to approximate the full dynamical correlation energy of strongly correlated systems, and we recently proposed compressed multistate pair-density functional theory (CMS-PDFT) to treat closely coupled states. In the present paper, we report the implementation of analytic gradients for CMS-PDFT in both OpenMolcas and PySCF, and we illustrate the use of these gradients by applying the method to the excited states of formaldehyde and phenol.

The environment, poor nutrition, bad habits - all this affects the composition of the blood. Don't self-medicate! If you consult a doctor in a timely manner, you can avoid serious consequences for the body.

Separately, I would like to remind women that without a sufficient amount of iron in the blood there will be no luxurious shiny hair, long nails and healthy skin. Choose trusted clinics with a modern approach to identifying the causes, symptoms and treatment of anemia.

description: The semi-canonical second-order optimised effective potential (OEP2-sc) method [R.J. Bartlett, I. Grabowski, S. Hirata and S. Ivanov, J. Chem. Phys. 122, 034104 (2005). doi:10.1063/1.1809605] is one of the most stable and efficient correlated OEP approaches. In this work, we introduce its scaled-opposite-spin (SOS) variant, named OEP2-SOS-sc. This new method further improves over the OEP2-sc for various properties, including correlation potentials, relaxed densities, and energies, fully retaining the good stability of the original approach. Thus, the OEP2-SOS-sc is an efficient and promising tool for high-level density functional theory simulations.

description: The potential behind the horizon of an eternal black hole in classical theories is described in terms of data that is available to an external observer -- the reflection coefficient of a wave that scatters on the black hole. In GR and perturbative string theory (in $α'$), the potential is regular at the horizon and it blows up at the singularity. The exact reflection coefficient, that is known for the $SL(2,\mathbb{R})_k/U(1)$ black hole and includes non-perturbative $α'$ effects, seems however to imply that there is a highly non-trivial structure just behind the horizon.

description: We introduce $Recursive~Jigsaw~Reconstruction$, a technique for analyzing reconstructed particle interactions in the presence of kinematic and combinatoric unknowns associated with unmeasured and indistinguishable particles, respectively. By factorizing missing information according to decays and rest frames of intermediate particles, an interchangeable and configurable set of $Jigsaw~Rules$, algorithms for resolving these unknowns, are applied to approximately reconstruct decays with arbitrarily many particles, in their entirety. That the Recursive Jigsaw Reconstruction approach can be used to analyze $any$ event topology of interest, with any number of ambiguities, is demonstrated through a twelve different simulated LHC physics examples. These include the production and decay of $W$, $Z$, Higgs bosons, and supersymmetric particles including gluinos, stop quarks, charginos, and neutralinos.
Non-Minimal Flavored ${\bf S}_{3}\otimes {\bf Z}_{2} $ Left-Right Symmetric Model

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We propose a non-minimal left-right symmetric model (LRSM) with Parity Symmetry where the fermion mixings arise as result of imposing an ${\bf S}_{3}\otimes {\bf Z}_{2}$ flavor symmetry, and an extra ${\bf Z}^{e}_{2}$ symmetry is considered to suppress some Yukawa couplings in the lepton sector. As a consequence, the effective neutrino mass matrix possesses approximately the $μ-τ$ symmetry. The breaking of the $μ-τ$ symmetry induces sizable non zero $θ_{13}$, and the deviation of $θ_{23}$ from $45^{\circ}$ is strongly controlled by an $ε$ free parameter and the complex neutrino masses. Then, an analytic study on the extreme Majorana phases is done since these turn out to be relevant to enhance or suppress the reactor and atmospheric angle. So that we have constrained the parameter space for the $ε$ parameter and the lightest neutrino mass that accommodate the mixing angles. The highlighted results are: a) the normal hierarchy is ruled out since the reactor angle comes out being tiny, for any values of the Majorana phases; b) for the inverted hierarchy there is one combination in the extreme phases where the values of the reactor and atmospheric angles are compatible up to $2, 3~σ$ of C. L., but the parameter space is tight; c) the model favors the degenerate ordering for one combination in the extreme Majorana phases. In this case, the reactor and atmospheric angle are compatible with the experimental data for a large set of values of the free parameters. Therefore, this model may be testable by the future result that the Nova and KamLAND-Zen collaborations will provide.

description: We consider a rotor made of two camphor disks glued below the ends of a plastic stripe. The disks are floating on a water surface and the plastic stripe does not touch the surface. The system can rotate around a vertical axis located at the center of the stripe. The disks dissipate camphor molecules. The driving momentum comes from the nonuniformity of surface tension resulting from inhomogeneous surface concentration of camphor molecules around the disks. We investigate the stationary angular velocity as a function of rotor radius $\ell$. For large $\ell$ the angular velocity decreases for increasing $\ell$. At a specific value of $\ell$ the angular velocity reaches its maximum and, for short $\ell$ it rapidly decreases. Such behaviour is confirmed by a simple numerical model. The model also predicts that there is a critical rotor size below which it does not rotate. Within the introduced model we analyze the type of this bifurcation.

description: We report on accurate variational calculations of the Born–Oppenheimer potential for excited states of the hydrogen molecule with Π,Δ, and Φ symmetries. The obtained potential energy curves reach the relative precision of 10−9 or better along internuclear distances of 0.01–20 au. Calculations rely on the recursive evaluation of two-centre two-electron molecular integrals with exponential functions in arbitrary precision arithmetics. Our results for most of the states are the first-ever reported, and for the previously calculated states constitute an improvement by several orders of magnitude.

description: Raman intensities in molecular spectra are usually computed within double harmonic approximation. This procedure relies on treating a vibrating molecule as a collection of harmonic oscillators and on the assumption that polarisability tensor invariants display linear variations around the molecular equilibrium geometry. This methodology, originally formulated by Placzek, constitutes the theoretical foundation for computing Raman intensities in standard quantum chemistry packages. However, the two assumptions underlying double harmonic approximation have not been sufficiently tested. In this work, we employed exact anharmonic ro-vibrational wave functions and distance-dependent polarisability invariants together with their harmonic approximants to investigate the discrepancies in Raman intensities of the fundamental transitions in 12 diatomic molecules, caused by double harmonic approximation. We found that: (i) the errors in total Raman intensities were between −8.2% and +9.5%, (ii) the largest discrepancy was observed for F2, where the polarisability invariants could not be adequately modelled by their linear approximants, and (iii) quantum chemical methods fail to predict reliable polarisability invariants at non-equilibrium molecular geometries; the associated errors in Raman intensities are huge and completely overshadow the shortcomings of double harmonic approximation. We communicate here an urgent need for developing accurate methods capable of computing reliable polarisabilities also at distorted geometries.

description: In the first part of this paper we review a mathematical model for the onset and progression of Alzheimer's disease (AD) that was developed in subsequent steps over several years. The model is meant to describe the evolution of AD in vivo. In [Y. Achdou et al., 2013] we treated the problem at a microscopic scale, where the typical length scale is a multiple of the size of the soma of a single neuron. Subsequently, in [M. Bertsch at al., 2016] we concentrated on the macroscopic scale, where brain neurons are regarded as a continuous medium, structured by their degree of malfunctioning. In the second part of the paper we consider the relation between the microscopic and the macroscopic models. In particular we show under which assumptions the kinetic transport equation, which in the macroscopic model governs the evolution of the probability measure for the degree of malfunctioning of neurons, can be derived from a particle-based setting. In the microscopic model we consider basically mechanism i), modelling it by a system of Smoluchowski equations for the amyloid concentration (describing the agglomeration phenomenon), with the addition of a diffusion term as well as of a source term on the neuronal membrane. At the macroscopic level instead we model processes i) and ii) by a system of Smoluchowski equations for the amyloid concentration, coupled to a kinetic-type transport equation for the distribution function of the degree of malfunctioning of the neurons. The second equation contains an integral term describing the random onset of the disease as a jump process localized in particularly sensitive areas of the brain. Even though we deliberately neglected many aspects of the complexity of the brain and the disease, numerical simulations are in both cases (microscopic and macroscopic) in good qualitative agreement with clinical data.

description: The dynamics of interacting quantum vortices in a quasi-two-dimensional spatially inhomogeneous Bose-Einstein condensate, whose equilibrium density vanishes at two points of the plane with a possible presence of an immobile vortex with a few circulation quanta at each point, has been considered in a hydrodynamic approximation. A special class of density profiles has been chosen, so that it proves possible to calculate analytically the velocity field produced by point vortices. The equations of motion have been given in a noncanonical Hamiltonian form. The theory has been generalized to the case where the condensate forms a curved quasi-two-dimensional shell in the three-dimensional space.

Altmetric Attention Score
Altmetric.com

description: Altmetrics encompass a broad set of metrics derived from the multiple interactions produced around science in social media. It is a complex and liquid phenomenon that is further complicated by the creation of proposals such as the Altmetric Attention Score (AAS). However, there are only studies that analyze the accumulation of mentions in different sources but without considering the volatility of these and their impact on such aggregated metrics. Our main objective is to study how the Altmetric Attention Score value fluctuates over time. For this we use a set of 73,367 scholarly outputs published between 2012 and 2021 and indexed in the Web of Science Information Science & Library Science category. We then queried the DOIs of these publications on Altmetric.com monthly between February 2022 and July 2022 to obtain their Altmetric Attention Score. Thus, changes in this metric were studied for 26,474 ISLS publications with altmetrics mentions over 6 months. As a result, we found that in this period 10% of the publications have reduced their AAS value. A metric anomaly has been identified both at the paper level and at the category level

description: When preparing to enter the senior years of secondary education, Australian students choose whether to undertake a vocational or an academic pathway. For all students, this decision-making process is complex, and existing research suggests even more so for Aboriginal and Torres Strait Islander students from remote communities studying at boarding schools away from their homes and families. By drawing on critical theory to conduct this qualitative study, the voices of past students who identify as Aboriginal and/or Torres Strait Islander were centred while investigating the senior schooling pathway choices made by Aboriginal and Torres Strait Islander students from remote communities at Queensland boarding schools. The past student experiences were triangulated with a focus group interview with select staff at a Queensland boarding school, and my own autoethnographic reflections. The findings of the thematic content analysis was further augmented through a process of descriptive statistics to summarise publicly accessible data. The key finding that emerged from this study was that First Nations students from remote communities are more likely to undertake a non-academic pathway in their senior years at boarding schools in Queensland despite the possibility that this choice does not align with their genuine pathway preferences. Historical and hegemonic constructs continue to permeate the education system, and unless change occurs at a systemic level, individual staff or school-based initiatives will not result in shifts in available opportunities for First Nations students to freely select from either an academic or a non-academic pathway.

description: We analyze the effects of noncommutativity in conformal quantum mechanics (CQM) using the $κ$-deformed space-time as a prototype. Upto the first order in the deformation parameter, the symmetry structure of the CQM algebra is preserved but the coupling in a canonical model of the CQM gets deformed. We show that the boundary conditions that ensure a unitary time evolution in the noncommutative CQM can break the scale invariance, leading to a quantum mechanical scaling anomaly. We calculate the scaling dimensions of the two and three point functions in the noncommutative CQM which are shown to be deformed. The $AdS_2/CFT_1$ duality for the CQM suggests that the corresponding correlation functions in the holographic duals are modified. In addition, the Breitenlohner-Freedman bound also picks up a noncommutative correction. The strongly attractive regime of a canonical model of the CQM exhibit quantum instability. We show that the noncommutativity softens this singular behaviour and its implications for the corresponding holographic duals are discussed.

description: The Cahn-Hilliard system has been used to describe a wide number of phase separation processes, from co-polymer systems to lipid membranes. In this work the convergence properties of a closest-point based scheme is investigated. In place of solving the original fourth-order system directly, two coupled second-order systems are solved. The system is solved using an incomplete Schur-decomposition as a preconditioner. The results indicate that with a sufficiently high-order time discretization the method only depends on the underlying spatial resolution.

description: The integrity of messages in vehicular ad-hoc networks has been extensively studied by the research community, resulting in the IEEE~1609.2 standard, which provides typical integrity guarantees. However, the correctness of message contents is still one of the main challenges of applying dependable and secure vehicular ad-hoc networks. One important use case is the validity of position information contained in messages: position verification mechanisms have been proposed in the literature to provide this functionality. A more general approach to validate such information is by applying misbehavior detection mechanisms. In this paper, we consider misbehavior detection by enhancing two position verification mechanisms and fusing their results in a generalized framework using subjective logic. We conduct extensive simulations using VEINS to study the impact of traffic density, as well as several types of attackers and fractions of attackers on our mechanisms. The obtained results show the proposed framework can validate position information as effectively as existing approaches in the literature, without tailoring the framework specifically for this use case.

As we had shown, the key to making a scalable decentralized visual place recognition lies in exploting deterministic key assignment in a distributed key-value map. Through this, it is possible to reduce bandwidth by up to a factor of n, the robot count, by casting visual place recognition to a key-value lookup problem. In [1], we exploited this for the bag-of-words method [3], [4]. Our method of casting bag-of-words, however, results in a complex decentralized system, which has inherently worse recall than its centralized counterpart. In this paper, we instead start from the recent full-image description method NetVLAD [5]. As we show, casting this to a key-value lookup problem can be achieved with k-means clustering, and results in a much simpler system than [1]. The resulting system still has some flaws, albeit of a completely different nature: it suffers when the environment seen during deployment lies in a different distribution in feature space than the environment seen during training.

description: In this study, we present a multi-product, multi-period inventory control problem under uncertainty in product demands that emerges in the fashion industry. A two-stage stochastic model is proposed to design a planning strategy where the total cost incurred by purchase orders, inventory and shortage is minimised. We incorporate the Conditional Value at Risk (CVaR) within the formulation to address exogenous uncertainty. An industrial case study involving a Mexican fashion retail company was considered to assess the performance of the two-stage stochastic model. Scenarios were considered using historical data provided by the company. A sensitivity analysis was also conducted on risk-aversion parameters to assess how the values of these parameters affect the behaviour of the proposed formulation. The results show that the proposed two-stage stochastic formulation is an efficient and practical approach to handle exogenous uncertainty in industrial-scale capacitated lot-sizing problems.

description: We find general deformations of BTZ spacetime and identify the corresponding thermofield initial states of the dual CFT. We deform the geometry by introducing bulk fields dual to primary operators and find the back-reacted gravity solutions to the quadratic order of the deformation parameter. The dual thermofield initial states can be deformed by inserting arbitrary linear combination of operators at the mid-point of the Euclidean time evolution that appears in the construction of the thermofield initial states. The deformed geometries are dual to thermofield states without deforming the boundary Hamiltonians in the CFT side. We explicitly demonstrate that the AdS/CFT correspondence is not a linear correspondence in the sense that the linear structure of Hilbert space of the underlying CFT is realized nonlinearly in the gravity side. We also find that their Penrose diagrams are no longer a square but elongated horizontally due to deformation. These geometries describe a relaxation of generic initial perturbation of thermal system while fixing the total energy of the system. The coarse-grained entropy grows and the relaxation time scale is of order $β/2π$. We clarify that the gravity description involves coarse-graining inevitably missing some information of nonperurbative degrees.

description: Биотехнологические методы широко применяются в практике мирового сельскохозяйственного производства, причем наиболее широко из них является метод in vitro, который в последние годы применяется для создания новых плантаций нетрадиционных растений. Одним из преимуществ метода in vitro является то, что он позволяет выращивать множество микрорастений в небольших лабораторных условиях независимо от времени года. Поэтому важным научно-практическим и актуальным вопросом является использование метода микроклонального размножения in vitro ценного растения стевии, выбор оптимальной питательной среды для культуры тканей, правильное проведение процесса стерилизации, выращивание корней, перенос микро рассаду в нестерильные условия и доставить ее в открытый грунт.

description: We clarify the role of the dual coordinates as described from the perspectives of the Buscher T-duality rules and Double Field Theory. We show that the T-duality angular dual coordinates cannot be identified with Double Field Theory dual coordinates in any of the proposals that have been made in the literature for patching the doubled spaces. In particular, we show with explicit examples that the T-duality angular dual coordinates can have non-trivial transition functions over a spacetime and that their identification with the Double Field Theory dual coordinates is in conflict with proposals in which the latter remain inert under the patching of the B-field. We then demonstrate that the Double Field Theory coordinates can be identified with some C-space coordinates and that the T-dual spaces of a spacetime are subspaces of the gerbe in C-space. The construction provides a description of both the local $O(d,d)$ symmetry and the T-dual spaces of spacetime.

description: During cooling, conventional martensitic transformation can only be realized from austenite to martensite. Recently, a so-called reentrant martensitic transformation attracted much interest due to an additional transformation from martensite to austenite during further cooling. Obviously, materials with this reentrant transformation will increase the number of physical effects and possible applications. However, until now, only bulk samples have been available, which are not suitable for applications in micro-devices. In this work, we focus on the Co-Cr-Ga-Si system and examine the suitability of this system for the growth of thin films. We observed that the films grow epitaxially on MgO (100) substrates and exhibit a martensitic transformation if deposited at a sufficiently high temperature or with an additional heat treatment. Films within the austenite state are ferromagnetic while films within the martensitic state just exhibit a very low ferromagnetic order. We sincerely make a statement that our work is arranged in the scientific way with highly novelty. So far, the research and reports on reentrant martensitic materials are very less. We make a starting in thin films to arouse enthusiasm for research on this novel shape memory materials. Although we could not observe a reentrant martensitic transformation in the additional experiments due to the limited conditions, we consider our work as a substantial advance in science since we present for the first time a route to prepare epitaxial films from this emerging material, which allowed analyzing its functional properties. So, we think our work is at the high novelty. We consider our manuscript relevant for the broad interdisciplinary readership of Science and Technology of Advanced Materials. First, it is relevant for material scientists, as it addresses reentrant martensite as an emerging class of functional materials. Second, it is interesting for physicist, as our epitaxial films enable probing the underlying mechanism driving a reentrant transition. Third, it is interesting for engineers, as reentrant films are required for microsystems based on this multifunctional material. We thank you for your consideration and your time. We hope that our work is now acceptable for publication in Science and Technology of Advanced Materials.

description: In this paper, we provide a novel dataset designed for camera invariant color constancy research. Camera invariance corresponds to the robustness of an algorithm's performance when run on images of the same scene taken by different cameras. Accordingly, images in the database correspond to several lab and field scenes each of which are captured by three different cameras with minimal registration errors. The lab scenes are also captured under five different illuminations. The spectral responses of cameras and the spectral power distributions of the lab light sources are also provided, as they may prove beneficial for training future algorithms to achieve color constancy. For a fair evaluation of future methods, we provide guidelines for supervised methods with indicated training, validation and testing partitions. Accordingly, we evaluate a recently proposed convolutional neural network based color constancy algorithm as a baseline for future research. As a side contribution, this dataset also includes images taken by a mobile camera with color shading corrected and uncorrected results. This allows research on the effect of color shading as well.

Topological Properties of a Coupled Spin-Photon System Induced by Damping

description: We experimentally examine the topological nature of a strongly coupled spin-photon system induced by damping. The presence of both spin and photonic losses results in a non-Hermitian system with a variety of exotic phenomena dictated by the topological structure of the eigenvalue spectra and the presence of an exceptional point (EP), where the coupled spin-photon eigenvectors coalesce. By controlling both the spin resonance frequency and the spin-photon coupling strength we observe a resonance crossing for cooperativities above one, suggesting that the boundary between weak and strong coupling should be based on the EP location rather than the cooperativity. Furthermore we observe dynamic mode switching when encircling the EP and identify the potential to engineer the topological structure of coupled spin-photon systems with additional modes. Our work therefore further highlights the role of damping within the strong coupling regime, and demonstrates the potential and great flexibility of spin-photon systems for studies of non-Hermitian physics.

description: We compute holographic Rényi entropies for spherical entangling surfaces on the boundary while considering third order Lovelock gravity with negative cosmological constant in the bulk. Our study shows that third order Lovelock black holes with hyperbolic event horizon are unstable, and at low temperatures those with smaller mass are favoured, giving rise to first order phase transitions in the bulk. We determine regions in the Lovelock parameter space in arbitrary dimensions, where bulk phase transitions happen and where boundary causality constraints are met. We show that each of these points corresponds to a dual boundary conformal field theory whose Rényi entropy exhibits a kink at a certain critical index $n$.

description: This article serves as the second part in a two-part series that provides an overview of the reverse auction concept, building on the best research in the field of supply chain management. In this instalment, we look at the concerns involved in making reverse auctions work in practice – the implementation issues. Frist, we look at when reverse auctions should – and should not – be utilized by a buying organization. We then examine the decision rules that should be used in determining which of the competing suppliers wins the reverse auction. Next, we look at the best research available as to how the use of reverse auctions impacts the buyer-seller relationship. Finally, we examine what is in essence a “make or buy” decision in regards to whether the purchasing organization should run an auction in-house or make use of the services of a third-party “market maker
