description: Das Bibliotheksservice-Zentrum Baden-Württemberg (BSZ) und die Verbundzentrale des Gemeinsamen Bibliotheksverbundes (VZG) haben am 03. September 2015 eine Vereinbarung über eine enge strategische Kooperation unterzeichnet. Kern der Vereinbarung ist die Vereinigung der beiden Verbundsysteme zu einer gemeinsamen Katalogisierungsplattform im Jahre 2017. Kurzfristige Ziele sind mit Umstieg auf RDA die Verwendung einheitlicher Katalogisierungs- und Anwendungsrichtlinien sowie die Einführung eines gemeinsamen Katalogisierungsformates. Im ersten Schritt wird ein Pool von gemeinsam genutzten Metadaten zu E-Books (E-Book-Pool) aufgebaut. Zusammen mit einem neu entwickelten Tool zur Verwaltung von E-Book-Metadaten, Lizenzen, Paketen und lokalen Anforderungen (EBM-Tool) soll die Information über verfügbare Metadaten verbessert und die Exemplardaten-Erzeugung weitgehend automatisiert werden. Für Alma-Kunden in Deutschland werden BSZ, VZG (GBV) und hbz (Hochschulbibliothekzentrum NRW) verbundübergreifende Services bereitstellen. Hierzu bilden die drei Verbundzentralen ein Konsortium zum Aufbau und zum Management einer Common Bibliographic Data Zone (CBDZ) aus allen Daten der drei Verbundregionen. Ex Libris stellt dem Konsortium hierfür eine Netzwerkzone als CBDZ zur Verfügung. Im Vortrag wird über den aktuellen Stand beider Großprojekte berichtet.

description: Along with crystallized intelligence (Gc), domain-specific knowledge (Gkn) is an important ability within the nomological net of acquired knowledge. Although Gkn has been shown to predict important life outcomes, only a few standardized tests measuring Gkn exist, especially for the adult population. Complicating things, Gkn tests from different cultural circles cannot simply be translated as they need to be culture specific. Hence, this study aimed to develop a Gkn test culturally sensitive to a German population and to provide initial evidence for the resulting scores’ psychometric quality. Existing Gkn tests often mirror a school curriculum. We aimed to operationalize Gkn not solely based upon a typical curriculum to investigate a research question regarding the curriculum dependence of the resulting Gkn structure. A set of newly developed items from a broad range of knowledge categories was presented online to 1450 participants divided into a high (fluid intelligence, Gf) Gf (n = 415) and an unselected Gf subsample (n = 1035). Results support the notion of a hierarchical model comparable to the one curriculum-based tests scores have, with one factor at the top and three narrower factors below (Humanities, Science, Civics) for which each can be divided into smaller knowledge facets. Besides this initial evidence regarding structural validity, the scale scores’ reliability estimates are reported, and criterion validity-related evidence based on a known-groups design is provided. Results indicate the psychometric quality of the scores and are discussed.

description: Die zentrale Problemstellung dieser Arbeit entstammt dem operationellen Supply Chain Management. Es liegen Bestellungen von Kunden vor, für die jeweils zu entscheiden ist, ob sie angenommen werden sollen. Die angenommenen Bestellungen sind auf einem vorhandenen Maschinenpark zu produzieren und fertiggestellte Bestellungen sind an den jeweiligen Kunden auszuliefern. Zu diesem Zwecke steht eine Transporterflotte bereit, wobei die Auslieferung in der Form "Sammelauslieferung mit Rundreise" erfolgen soll. Diese allgemeine Problemstellung lässt sich anhand von 13 Eigenschaften, die unterschiedlich ausgeprägt sein können, weiter präzisieren. Es wird ein Modellierungsbaukasten entwickelt, um jede spezielle Problemstellung modellieren und mit Hilfe des MIP-Solvers CPLEX hinreichend schnell lösen zu können. Zu den weiteren Kernpunkten dieser Arbeit gehören die Entwicklung eines Branch&Bound-Verfahrens für eine spezielle Problemstellung und die Konzeption neuer, hinsichtlich ihrer Laufzeit verbesserter Modelle für das "Split Delivery Vehicle Routing Problem" sowie das "Vehicle Routing Problem With Time Windows And Multiple Use Of vehicles". This thesis addresses the field of operational supply chain management. Customers place orders which have to be accepted or declined. If an order is accepted, it has to be produced in an existing plant. Completed orders have to be shipped to the corresponding customer by an existing fleet of vehicles, using the method "batch delivery with routing". This very general problem is stated more precisely by identifying 13 properties and their possible characteristics. A tool kit is developed for modelling each of the possible problem types and solving the respective problem by the MIP solver CPLEX efficiently. Furthermore, the contribution develops a branch and bound algorithm for a specific problem type and improved models for the "Split Delivery Vehicle Routing Problem" and the "Vehicle Routing Problem With Time Windows And Multiple Use Of vehicles".

description: The cosmic-ray hydrogen and helium ($^1$H, $^2$H, $^3$He, $^4$He) isotopic composition has been measured with the satellite-borne experiment PAMELA, which was launched into low-Earth orbit on-board the Resurs-DK1 satellite on June 15th 2006. The rare isotopes $^2$H and $^3$He in cosmic rays are believed to originate mainly from the interaction of high energy protons and helium with the galactic interstellar medium. The isotopic composition was measured between 100 and 1100 MeV/n for hydrogen and between 100 and 1400 MeV/n for helium isotopes using two different detector systems over the 23rd solar minimum from July 2006 to December 2007.

description: An information theoretical model for quantum secret sharing was introduced by A. C. A. Nascimento et al.[Quantum Inf. Comput. Vol.5,1,205,68-79(2003)], which was analyzed by quantum information theory. In this paper, we analyze this information theoretical model using the properties of the quantum access structure. By the analysis we propose a generalized model definition for the quantum secret sharing schemes. In our model, there are more quantum access structures which can be realized by our generalized quantum secret sharing schemes than those of the previous one. In addition, we also analyse two kinds of important quantum access structures to illustrate the existence and rationality of the generalized quantum secret sharing schemes and consider the security of the scheme by simple examples.

description: The decays of $η$ and $η^\prime$ mesons provide unique opportunities for testing the properties of low energy Quantum Chromodynamics and for the search of new physics beyond the Standard Model. However, recent experimental results on the rare decays of $η^{\left(\prime\right)}\rightarrowπ^0\left(η\right)γγ$ cannot be self-consistently described by the combination of the Vector Meson Dominance and Linear Sigma Model employing the same set of parameters. We show that this tension can be attributed to the presence of a leptophobic dark photon $\mathcal{B}$, and find representative values of the parameters which provide consistent description of these three decays, simultaneously. Unlike existing strategies of Dalitz analysis searching for the bump at $m_\mathcal{B}$, we propose the usage of mismatch between these decays to constrain the parameters of the hypothetical dark photon.

description: There exist two kinds of stochastic gravitational-wave backgrounds associated with the primordial curvature perturbations. One is called induced gravitational wave due to the nonlinear coupling of curvature perturbations to tensor perturbations, while the other is produced by coalescences of binary primordial black holes formed when the large amplitude curvature perturbations reenter the horizon in the radiation dominant era. In this paper we find a quite useful relation for the peak frequencies of these two stochastic gravitational-wave backgrounds. This relation can not only offer a smoking-gun criterion for the existence of primordial black holes, but also provide a method for measuring the Hubble constant $H_0$ by multiband observations of the stochastic gravitational-wave backgrounds.

description: We study a classical model of thermally fluctuating polymers confined to two dimensions, experiencing a grooved periodic potential, and subject to pulling forces both along and transverse to the grooves. The equilibrium polymer conformations are described by a mapping to a quantum system with a non-Hermitian Hamiltonian and with fermionic statistics generated by noncrossing interactions among polymers. Using molecular dynamics simulations and analytical calculations, we identify a localized and a delocalized phase of the polymer conformations, separated by a delocalization transition which corresponds (in the quantum description) to the breakdown of a band insulator when driven by an imaginary vector potential. We calculate the average tilt of the many-body system, at arbitrary shear values and filling density of polymer chains, in terms of the complex-valued non-Hermitian band structure. We find the critical shear value, the localization length, and the critical exponent by which the shear modulus diverges in terms of the branch points (exceptional points) in the band structure at which the bandgap closes. We also investigate the combined effects of non-Hermitian delocalization and localization due to both periodicity and disorder, uncovering preliminary evidence that while disorder favours localization at high values, it encourages delocalization at lower values.

description: Distributional forecasts are important for a wide variety of applications, including forecasting epidemics. Often, forecasts are miscalibrated, or unreliable in assigning uncertainty to future events. We present a recalibration method that can be applied to a black-box forecaster given retrospective forecasts and observations, as well as an extension to make this method more effective in recalibrating epidemic forecasts. This method is guaranteed to improve calibration and log score performance when trained and measured in-sample. We also prove that the increase in expected log score of a recalibrated forecaster is equal to the entropy of the PIT distribution. We apply this recalibration method to the 27 influenza forecasters in the FluSight Network and show that recalibration reliably improves forecast accuracy and calibration. This method is effective, robust, and easy to use as a post-processing tool to improve epidemic forecasts.

description: Au nanoclusters are of technological relevance for catalysis, photonics, sensors, and of fundamental scientific interest owing to planar to globular structural transformation at an anomalously high number of atoms i.e. in the range 12-14. The nature and causes of this transition remain a mystery. In order to unravel this conundrum, high throughput density functional theory (DFT) calculations, coupled with a global structural optimization scheme based on a modified genetic algorithm (GA) are conducted. More than 20,000 Au$_{12}$, Au$_{13}$, and Au$_{14}$ nanoclusters are evaluated. With any DFT functional, globular and planar structures coexist across the size range of interest. The planar-globular transition is gradual at room temperature rather than a sharp transition as previously believed. The effects of anionicity, $\textit{s-d}$ band hybridization and long range interactions on the dimensional transition are quantified by using the structures adjacent to minima. Anionicity marginally changes the relative stability of the clusters. The degree of $\textit{s-d}$ hybridization is varied via changing the Hubbard U value which corroborate that $\textit{s-d}$ hybridization alone does not stabilize planar structures. van der Waals interactions, on the other hand, stabilize globular structures. These results elucidate the balance between the different reasons of the dimensional transition in gold nanoclusters.

We prove that, for the quasi-periodic Schrödinger operators with small Gevrey potentials, the length of spectral gaps decays sub-exponentially with respect to its labelling, the long range duality operator has pure point spectrum with sub-exponentially decaying eigenfunctions for almost all phases and the spectrum is an interval for discrete Schrödinger operator acting on $ \mathbb{Z}^d $ with small separable potentials. All these results are based on a refined KAM scheme, and thus are perturbative.

description: We develop a statistical test on the expected difference in age estimates of two coeval stars in detached double-lined eclipsing binary systems that are only caused by observational uncertainties. We focus on stars in the mass range [0.8; 1.6] Msun, and on stars in the main-sequence phase. The ages were obtained by means of the maximum-likelihood SCEPtER technique. The observational constraints used in the recovery procedure are stellar mass, radius, effective temperature, and metallicity [Fe/H]. We defined the statistic W computed as the ratio of the absolute difference of estimated ages for the two stars over the age of the older one. We determined the critical values of this statistics above which coevality can be rejected. The median expected difference in the reconstructed age between the coeval stars of a binary system -- caused alone by the observational uncertainties -- shows a strong dependence on the evolutionary stage. This ranges from about 20% for an evolved primary star to about 75% for a near ZAMS primary. The median difference also shows an increase with the mass of the primary star from 20% for 0.8 Msun stars to about 50% for 1.6 Msun stars. The reliability of these results was checked by repeating the process with a grid of stellar models computed by a different evolutionary code. We show that the W test is much more sensible to age differences in the binary system components than the alternative approach of comparing the confidence interval of the age of the two stars. We also found that the distribution of W is, for almost all the examined cases, well approximated by beta distributions. The proposed method improves upon the techniques that are commonly adopted for judging the coevality of an observed system. It also provides a result founded on reliable statistics that simultaneously accounts for all the observational uncertainties.

Semiconductor nanolasers in living cells
Creators: name: Fikouras, Alasdair
Publisher: name: The University of St Andrews
Year: 2020

description: In recent years there have been significant advancements in the miniaturisation of semiconductor laser devices, with optimised structures reaching extremely low thresholds, and operating at room temperature. This progress has enabled the demonstration of intracellular lasers, where miniaturised lasers are operated within living cells. Further developments in this new field focused on the optimisation of laser geometries as a potential method to increase the intensity and spectral resolution provided, over conventional biophotonic imaging approaches, using e.g. fluorophores and quantum dots. These intracellular lasers provide opportunities for sensing and multiplexing that were not possible with established techniques. The focus of this PhD was on integrating these two research frontiers. It involved the fabrication, characterisation, and application of III-V, semiconductor nanodisk whispering gallery mode (WGM) lasers. These were processed to be biocompatible and applied as a biophotonic tool. The tiny resonator volumes - substantially smaller than the nucleus of a cell - could be easily integrated into a variety of cell types, including neurons and immune T-cells that had not been previously capable of internalising lasers. The minimal resonator volume allowed inserting multiple lasers within cells, as they moved through confined environments, such as micro-pore epithelial analogues. Furthermore, the unique properties of WGM lasers were exploited to investigate cell dynamics as an intracellular local refractive index sensor. The realised lasers exhibited excellent properties, with high signal to noise ratios and very low laser thresholds (~0.13pJ). This was achieved by exploiting the large optical gain and high refractive index of GaInP/AlGaInP multi-quantum wells. In this work, the versatility of these lasers as a photonic platform was demonstrated by embedding them into transferable membranes. This was applied as a sensor for investigating epsilon near zero (ENZ) metamaterials and their optical enhancement properties, and additionally allowed the fabrication of different laser cavity designs such as a random network laser, to investigate the properties of random lasing.

description: Hearing loss is a major health problem and psychological burden in humans. Mouse models offer a possibility to elucidate genes involved in the underlying developmental and pathophysiological mechanisms of hearing impairment. To this end, large-scale mouse phenotyping programs include auditory phenotyping of single-gene knockout mouse lines. Using the auditory brainstem response (ABR) procedure, the German Mouse Clinic and similar facilities worldwide have produced large, uniform data sets of averaged ABR raw data of mutant and wildtype mice. In the course of standard ABR analysis, hearing thresholds are assessed visually by trained staff from series of signal curves of increasing sound pressure level. This is time-consuming and prone to be biased by the reader as well as the graphical display quality and scale. In an attempt to reduce workload and improve quality and reproducibility, we developed and compared two methods for automated hearing threshold identification from averaged ABR raw data: a supervised approach involving two combined neural networks trained on human-generated labels and a self-supervised approach, which exploits the signal power spectrum and combines random forest sound level estimation with a piece-wise curve fitting algorithm for threshold finding. We show that both models work well, outperform human threshold detection, and are suitable for fast, reliable, and unbiased hearing threshold detection and quality control. In a high-throughput mouse phenotyping environment, both methods perform well as part of an automated end-to-end screening pipeline to detect candidate genes for hearing involvement. Code for both models as well as data used for this work are freely available.

Exact renormalization group equation for lattice Ginzburg-Landau models adapted to the solution in the local potential approximation

description: The Wilson Green's function approach and, alternatively, Feynman's diffusion equation and the Hori representation have been used to derive an exact functional RG equation (EFRGE) that in the course of the RG flow interpolates between the interaction part of the lattice Ginzburg-Landau Hamiltonian and the logarithm of the generating functional of the S-matrix. Because the S-matrix vertices are the amputated correlation functions of the fluctuating field, it has been suggested that in the critical region the amputation of the long-range tails makes the S-matrix functional more localized and thus more amenable to the local potential approximation (LPA) than the renormalized free energy functional used in Wilson's EFRGE. By means of a functional Legendre transform the S-matrix EFRGE has been converted into an EFRGE for the effective action (EA). It has been found that the field-dependent part of EA predicted by the equation is the same as calculated within the known EA EFRGE approaches but in addition it is accurately accounts for the field-independent terms. These are indispensable in calculation of such important quantities as the the specific heat, the latent heat, etc. With the use of the derived EFRGE a closed expression for the renormalization counterterm has been obtained which when subtracted from the divergent solution of the Wetterich equation would lead to a finite exact expression for the EA thus making two approaches formally equivalent. The S-matrix equation has been found to be simply connected with a generalized functional Burgers' equation which establishes a direct correspondence between the first order phase transitions and the shock wave solutions of the RG equation. The transparent semi-group structure of the S-matrix RG equation makes possible the use of different RG techniques at different stages of the RG flow in order to improve the LPA solution.

description: The advance of quantum technology relies heavily on an accurate understanding of the unavoidable interactions between quantum systems and their environment. While it is often adequate to account for the environment using approximate time-local (i.e. Markovian) equations of motion, in many scenarios such a description fails, and a more general non-Markovian theory becomes necessary. The failure of Markovian descriptions concerns not only quantitative aspects of the reduced dynamics of a quantum system, but also qualitative and conceptual aspects, such as the failure of the quantum regression formula relating the system's dynamics to its multi-time correlations. Despite considerable progress in recent years, the description and simulation of non-Markovian open quantum systems remains a conceptual and computational challenge. In this thesis we develop a versatile set of numerical methods for non-Markovian open quantum systems by combining the so-called process tensor framework with the numerical power of tensor network methods. The recently introduced process tensor is an alternative approach to open quantum systems and is - unlike the canonical approach based on dynamical maps - well suited for a rigorous characterisation of non-Markovian open quantum systems. We construct and apply process tensors in a matrix product operator form (PT-MPO) to yield a numerically exact, yet efficient representation of non-Markovian open quantum systems, which allows for a variety of practical applications. Building on the PT-MPO we introduce general methods to (1) efficiently find optimal control procedures for non-Markovian open quantum systems, (2) compute the dynamics and multi-time correlations of chains of non-Markovian open quantum systems, and (3) construct a time-translational invariant PT-MPO, which allows efficient computation of steady states even in non-equilibrium non-Markovian scenarios.

description: Cobalt oxides have long been understood to display intriguing phenomena known as spin-state crossovers, where the cobalt ion spin changes vs. temperature, pressure, etc. A very different situation was recently uncovered in praseodymium-containing cobalt oxides, where a first-order coupled spin-state/structural/metal-insulator transition occurs, driven by a remarkable praseodymium valence transition. Such valence transitions, particularly when triggering spin-state and metal-insulator transitions, offer highly appealing functionality, but have thus far been confined to cryogenic temperatures in bulk materials (e.g., 90 K in Pr1-xCaxCoO3). Here, we show that in thin films of the complex perovskite (Pr1-yYy)1-xCaxCoO3-δ, heteroepitaxial strain tuning enables stabilization of valence-driven spin-state/structural/metal-insulator transitions to at least 291 K, i.e., around room temperature. The technological implications of this result are accompanied by fundamental prospects, as complete strain control of the electronic ground state is demonstrated, from ferromagnetic metal under tension to nonmagnetic insulator under compression, thereby exposing a potential novel quantum critical point.

description: The aim of this paper is twofold. Firstly, we investigate a finite sum involving the generalized falling factorial polynomials, in some special cases of which we express it in terms of the degenerate Stirling numbers of the second kind, the degenerate Bernoulli polynomials and the degenerate Frobenius-Euler polynomials. Secondly, we consider the degenerate Eulerian polynomials and deduce the generating function and a recurrence relation for them.

description: Pattern mining is a sub-field of data mining that focuses on discovering patterns in data to extract knowledge. There are various techniques to identify different types of patterns in a dataset. Constraint-based mining is a well-known approach to this where additional constraints are introduced to retrieve only interesting patterns. However, in these systems, there are limitations on imposing complex constraints. Constraint programming is a declarative methodology where the problem is modelled using constraints. Generic solvers can operate on a model to find the solutions. Constraint programming has been shown to be a well-suited and generic framework for various pattern mining problems with a selection of constraints and their combinations. However, a system that handles arbitrary constraints in a generic way has been missing in this field. In this thesis, we propose a declarative framework where the pattern mining models can be represented in high-level constraint specifications with arbitrary additional constraints. These models can be efficiently solved using underlying optimisations. The first contribution of this thesis is to determine the key aspects of solving pattern mining problems by creating an ad-hoc solver system. We investigate this further and create Constraint Dominance Programming (CDP) to be able to capture certain behaviours of pattern mining problems in an abstract way. To that end, we integrate CDP into the high-level \essence pipeline. Early empirical evaluation presents that CDP is already competitive with current existing techniques. The second contribution of this thesis is to exploit an additional behaviour, the incomparability, in pattern mining problems. By including the incomparability condition to CDP, we create CDP+I, a more explicit and even more efficient framework to represent these problems. We also prototype an automated system to deduct the optimal incomparability information for a given modelled problem. The third contribution of this thesis is to focus on the underlying solving of CDP+I to bring further efficiency. By creating the Solver Interactive Interface (SII) on SAT and SMT back-ends, we highly optimise not only CDP+I but any iterative modelling and solving, such as optimisation problems. The final contribution of this thesis is to investigate creating an automated configuration selection system to determine the best performing solving methodologies of CDP+I and introduce a portfolio of configurations that can perform better than any single best solver. In summary, this thesis presents a highly efficient, high-level declarative framework to tackle pattern mining problems.
Quantifying Gender Biases Towards Politicians on Reddit

description: Despite attempts to increase gender parity in politics, global efforts have struggled to ensure equal female representation. This is likely tied to implicit gender biases against women in authority. In this work, we present a comprehensive study of gender biases that appear in online political discussion. To this end, we collect 10 million comments on Reddit in conversations about male and female politicians, which enables an exhaustive study of automatic gender bias detection. We address not only misogynistic language, but also other manifestations of bias, like benevolent sexism in the form of seemingly positive sentiment and dominance attributed to female politicians, or differences in descriptor attribution. Finally, we conduct a multi-faceted study of gender bias towards politicians investigating both linguistic and extra-linguistic cues. We assess 5 different types of gender bias, evaluating coverage, combinatorial, nominal, sentimental, and lexical biases extant in social media language and discourse. Overall, we find that, contrary to previous research, coverage and sentiment biases suggest equal public interest in female politicians. Rather than overt hostile or benevolent sexism, the results of the nominal and lexical analyses suggest this interest is not as professional or respectful as that expressed about male politicians. Female politicians are often named by their first names and are described in relation to their body, clothing, or family; this is a treatment that is not similarly extended to men. On the now banned far-right subreddits, this disparity is greatest, though differences in gender biases still appear in the right and left-leaning subreddits. We release the curated dataset to the public for future studies.
Taking off the edge -- simultaneous filament and end core formation

description: Simulations of idealised star-forming filaments of finite length typically show core growth which is dominated by two cores forming at its respective end. The end cores form due to a strong increasing acceleration at the filament ends which leads to a sweep-up of material during the filament collapse along its axis. As this growth mode is typically faster than any other core formation mode in a filament, the end cores usually dominate in mass and density compared to other cores forming inside a filament. However, observations of star-forming filaments do not show this prevalence of cores at the filament ends. We explore a possible mechanism to slow the growth of the end cores using numerical simulations of simultaneous filament and embedded core formation, in our case a radially accreting filament forming in a finite converging flow. While such a setup still leads to end cores, they soon begin to move inwards and a density gradient is formed outside of the cores by the continued accumulation of material. As a result, the outermost cores are not longer located at the exact ends of the filament and the density gradient softens the inward gravitational acceleration of the cores. Therefore, the two end cores do not grow as fast as expected and thus do not dominate over other core formation modes in the filament.

description: We investigate both the classical and quantum gravitational collapse of a charged, non-rotating $n$-dimensional BTZ black hole in AdS space. This is done by first deriving the conserved mass of a "spherically" symmetric domain wall, which is then taken as the classical Hamiltonian of the domain wall. In the classical picture, we show that, as far as the asymptotic observer is concerned, the details of the collapse depend on the amount of charge present in the domain wall. In the both the extremal and non-extremal cases, the collapse takes an infinite amount of observer time to complete. However, in the over-charged case, the collapse never actually occurs, instead one finds an oscillatory solution which prevents the formation of a naked singularity. As far as the infalling observer is concerned, the collapse is completed within a finite amount of proper time. Thus, the gravitational collapse follows that of the typical formation of a black hole via gravitational collapse. Quantum mechanically, in the absence of induced quasi-particle production and fluctuations of the metric geometry, we take primary interest in the behavior of the collapse near the horizon and near the classical singularity from the point of view of both asymptotic and infalling observers. For the asymptotic observer, we find that quantum effects near the horizon do not change the classical conclusions. For the infalling observer, the most interesting quantum mechanical effect are when the collapsing shell approaches the classical singularity. Here, we find, that the quantum effects in this region display non-local effects, which depend on the energy density of the domain wall.

The transport character of quantum state in one-dimensional coupled-cavity-arrays: effect of the number of photons and entanglement degree

description: The transport properties of the photons injected into one-dimensional coupled-cavity-arrays (CCAs) are studied. It is found that the number of photons cannot change the evolution cycle of the system and the time points at which W states and NOON state are obtained with a relatively higher probability. Transport dynamics in the CCAs exhibits that entanglement-enhanced state transmission is more effective phenomenon, and we show that for a quantum state with the maximum concurrence, it can be transmitted completely without considering the case of photon loss.
