description: The objective of this study was to investigate the role of surface charge, wettability, and dopants on physical, mechanical and in vitro biological properties of bulk and coated electrothermally polarized hydroxyapatite (HAp) ceramics. For this purpose, bulk pure HAp compacts were prepared by sintering at 1200oC for 2h and HAp coating was fabricated on Ti substrate. Thermally stimulated depolarization current (TSDC) analysis revealed that a maximum surface charge of 4.05 0.33 [mu]C/cm2 can be stored in bulk sintered HAp compacts while HAp coating samples exhibited a stored surface charge of 1.41 0.30 [mu]C/cm2. It has been observed that increasing the surface potential led to decreasing of hydrophobicity of HAp surface without introducing any other volumetric effects in the material. In vitro bioactivity and bone cell-materials interaction results proved that increasing surface energy and wettability on negatively charged HAp surface significantly accelerated the apatite mineralization process by selectively adsorbing Ca2+ ions which promoted better hFOB cell attachment, proliferation and faster cells differentiation, especially at early time points, over unpoled HAp surface. In contrast, positively poled HAp surface exhibited inhibited hFOB cell proliferation and growth. Furthermore, dopants were incorporated into pure HAp in different single, binary and ternary composition to achieve combined benefits of matching bone chemistry and polarization effect. Small addition of Mg2+ and combined addition of Mg2+-Sr2+ were found most optimal in enhancing density, mechanical properties as well as polarizability and charge storage ability of pure HAp. In vitro cell materials interaction study showed that presence of Mg2+ and Sr2+ can also significantly improved osteoblast activities on negatively charged surface. Finally, the interaction cell adhesive fibronectin protein on polarized doped and undoped HAp surfaces was investigated to get comprehensive understanding on cell-materials interactions. Protein study results confirmed that higher adsorption and better structural stability of fibronectin protein led to superior cell-materials interactions on negatively charged binary doped HAp surfaces over undoped HAp. Overall, the present research findings demonstrated the potency of developing electro-thermally polarized HAp ceramics which can provide a new basis for the development of a new generation of HAp based implants that can promote faster healing.

description: In this paper we develop a Jacobi-type algorithm for the approximate diagonalization of tensors of order $d\geq3$ via tensor trace maximization. For a general tensor this is an alternating least squares algorithm and the rotation matrices are chosen in each mode one-by-one to maximize the tensor trace. On the other hand, for symmetric tensors we discuss a structure-preserving variant of this algorithm where in each iteration the same rotation is applied in all modes. We show that both versions of the algorithm converge to the stationary points of the corresponding objective functions.

description: The effect of non-Hermiticity in band topology has sparked many discussions on non-Hermitian topological physics. It has long been known that non-Hermitian Hamiltonians can exhibit real energy spectra under the condition of parity-time ($PT$) symmetry -- commonly implemented with balanced loss and gain -- but only when non-Hermiticity is relatively weak. Sufficiently strong non-Hermiticity, on the other hand, will destroy the reality of energy spectra, a situation known as spontaneous $PT$-symmetry breaking. Here, based on non-reciprocal coupling, we show a systematic strategy to construct non-Hermitian topological systems exhibiting bulk and boundary energy spectra that are always real, regardless of weak or strong non-Hermiticity. Such nonreciprocal-coupling-based non-Hermiticity can directly drive a topological phase transition and determine the band topology, as demonstrated in a few non-Hermitian systems from 1D to 2D. Our work develops so far the only theory that can guarantee the reality of energy spectra for non-Hermitian Hamiltonians, and offers a new avenue to explore non-Hermitian topological physics.

description: We propose a formulation of lattice fermions with one-sided differences that is hermitian, chirally symmetric (barring a bare mass term) and completely free of doubling. To obtain the axial anomaly in perturbation theory it was necessary to break chiral symmetry on the lattice only through a bare mass term for the physical fermion. The chiral limit may be taken once the continuum limit is reached. We comment on the role of the mass term with examples elsewhere in field theory.

description: We obtain photon statistics by using a quantum jump approach tailored to a system in which one or two qubits are coupled to a one-dimensional waveguide. Photons confined in the waveguide have strong interference effects, which are shown to play a vital role in quantum jumps and photon statistics. For a single qubit, for instance, bunching of transmitted photons is heralded by a jump that increases the qubit population. We show that the distribution and correlations of waiting times offer a clearer and more precise characterization of photon bunching and antibunching. Further, the waiting times can be used to characterize complex correlations of photons which are hidden in $g^{(2)}(τ)$, such as a mixture of bunching and antibunching.

description: In this paper, we study the well-posedness theory and the scattering asymptotics for fourth-order Schrödinger equations (4NLS) on waveguide manifolds (semiperiodic spaces) $\mathbb{R}^d\times \mathbb{T}^n$, $d \geq 5$, $n=1,2,3$. The tori component $\mathbb{T}^n$ can be generalized to $n$-dimensional compact manifolds $\mathcal{M}^n$. First, we modify Strichartz estimates for 4NLS on waveguide manifolds, with which we establish the well-posedness theory in proper function spaces via the standard contraction mapping method. Moreover, we prove the scattering asymptotics based on an interaction Morawetz-type estimate established for 4NLS on waveguides. At last, we discuss the higher dimensional analogue, the focusing scenario and give some further remarks on this research line. This result can be regarded as the waveguide analogue of Pausader \cite{Pau2,Pau1,Pau3} and the 4NLS analogue of Tzvetkov-Visciglia \cite{TV2}.

Characterization of cobalt based catalysts for ethanol steam reforming

description: In order to gain insight into the cobalt-support interactions for designing a better supported cobalt catalyst system for hydrogen production via ethanol steam reforming, the catalytic properties of an unsupported active component, bulk cobalt oxides, were investigated. The phase transformation of cobalt oxides and the corresponding catalytic activity in ethanol steam reforming was studied. Through in-situ XRD and DRIFTS studies, it was discovered for the first time that two metallic phases (hcp and fcc cobalt) exist in cobalt under the reforming conditions and possess different activity for hydrogen production. Furthermore, the addition of CeO2 to cobalt was shown to hinder the sintering and the phase transformation in the hcp cobalt nanoparticles. Another promoting effect of CeO2 was found to divert the reaction pathways toward an increase of hydrogen selectivity. Thus, the hcp cobalt promoted by CeO2 shows a much higher catalytic activity for hydrogen production than an unpromoted cobalt catalyst. In a separate work, a novel supported cobalt catalyst system for ethanol steam reforming was further studied. CeO2-ZrO2 support was chosen for cobalt to study a possible synergistic effect of CeO2 and ZrO2 toward the reforming reaction. This synergistic effect promotes the catalytic activity of Co/CeO2-ZrO2 catalyst by suppressing methanation favored on ZrO2 supports, as well as by stabilizing the surface area which of CeO2 supported is much smaller due to sintering. In addition, a study regarding how various synthesis techniques as well as the prereduction process influence the catalytic properties of Co/CeO2-ZrO2 catalyst for ethanol steam reforming is presented. The supported catalysts were synthesized by incipient wetness impregnation and coprecipitation followed by detailed characterizations using nitrogen adsorption, TEM-EDX, XRD, H2-TPR, and CO chemisorption techniques. Metal-support interaction is shown during the pre-reduction of the impregnated catalyst and plays a crucial role in the enhancement of catalytic activity, which was not observed in the less active coprecipitated catalysts. Finally, the formation of the water-induced cobalt oxides by re-oxidizing the metallic cobalt in the pre-reduced Co/CeO2-ZrO2 catalyst was verified through in-situ TPR and in-situ XPS studies in water-assisted ethanol decomposition and ethanol steam reforming. The presence of these cobalt oxides in the catalyst is shown to be associated with the catalyst pre-reduction the feed stream conditions in the reaction.

description: We propose a new off-shell formulation for the massless ${\cal N}=1$ supersymmetric multiplet of integer superspin $s$ in four dimensions, where $s =2,3,\dots$ (the $s=1$ case corresponds to the gravitino multiplet). Its gauge freedom matches that of the superconformal superspin-$s$ multiplet described in arXiv:1701.00682. The gauge-invariant action involves two compensating multiplets in addition to the superconformal superspin-$s$ multiplet. Upon imposing a partial gauge fixing, this action reduces to the one describing the so-called longitudinal formulation for the massless superspin-$s$ multiplet. Our new model is shown to possess a dual realisation obtained by applying a superfield Legendre transformation. We present a non-conformal higher spin supercurrent multiplet associated with the new integer superspin theory. This fermionic supercurrent is shown to occur in the Fayet-Sohnius model for a massive ${\cal N}=2$ hypermultiplet. We also give a new off-shell realisation for the massless gravitino multiplet.

description: Communication among processes is generating considerable interest in the scientific computing community due to the increasing use of distributed memory systems. In the field of high energy physics (HEP), however, little research has been addressed on this topic. More precisely in ROOT I/O, the de facto standard for data persistence in HEP applications, no such feature is provided. In order to perform efficient and robust cross-node communications, we introduce the TMPIFile functionality into ROOT where Message Passing Interface (MPI) is used to pass data across the entire distributed system. In the case of ATLAS workflows, instead of writing to file, the compressed data for each node is now stored into the sender side of TMPIFile. After a certain amount of data is collected, the TMPIFile sender can automatically package the data into a memory buffer and send it via MPI. On the other end of the communication, a collector receives buffers from multiple senders, merges them into one file, and at last, writes the file into the disk. Multiple collectors can be created to avoid I/O contention. Test results will be shown from runs at NERSC and ALCF.

description: The Normalized Relative Compression (NRC) is a recent dissimilarity measure, related to the Kolmogorov Complexity. It has been successfully used in different applications, like DNA sequences, images or even ECG (electrocardiographic) signal. It uses a compressor that compresses a target string using exclusively the information contained in a reference string. One possible approach is to use finite-context models (FCMs) to represent the strings. A finite-context model calculates the probability distribution of the next symbol, given the previous $k$ symbols. In this paper, we introduce a generalization of the FCMs, called extended-alphabet finite-context models (xaFCM), that calculates the probability of occurrence of the next $d$ symbols, given the previous $k$ symbols. We perform experiments on two different sample applications using the xaFCMs and the NRC measure: ECG biometric identification, using a publicly available database; estimation of the similarity between DNA sequences of two different, but related, species -- chromosome by chromosome. In both applications, we compare the results against those obtained by the FCMs. The results show that the xaFCMs use less memory and computational time to achieve the same or, in some cases, even more accurate results.

description: Collembola is a highly diverse and abundant group of soil arthropods with chromosome numbers ranging from 5 to 11. Previous karyotype studies indicated that the Tomoceridae family possesses an exceptionally long chromosome. To better understand chromosome size evolution in Collembola, we obtained a chromosome-level genome of Yoshiicerus persimilis with a size of 334.44 Mb and BUSCO completeness of 97.0% (n = 1,013). Both genomes of Y. persimilis and Tomocerus qinae (recently published) have an exceptionally large chromosome (ElChr >100 Mb), accounting for nearly one-third of the genome. Comparative genomic analyses suggest that chromosomal elongation occurred independently in two species approximately 10 million years ago, rather than in the ancestor of the Tomoceridae family. The ElChr elongation was caused by large tandem and segmental duplications, as well as transposon proliferation, with genes in these regions experiencing weaker purifying selection (higher dN/dS) than conserved regions. Moreover, inter-genomic synteny analyses indicated that chromosomal fission/fusion events played a crucial role in the evolution of chromosome numbers (ranging from 5 to 7) within Entomobryomorpha. This study provides a valuable resource for investigating the chromosome evolution of Collembola.

description: To obtain a local description from highly accurate density functional theory codes that are based on modified plane wave bases, a transformation to a local orthonormal Wannier function basis is required. In order to do so while enforcing the constraints of the space group symmetry the Symmetry Conserving Maximally Projected Wannier Functions (SCMPWF) approach has been implemented in the Full-Potential-Local-Orbital code, FPLO. SCMPWFs represent the zeroth order approximation to maximally localized Wannier functions, projecting a subset of wave functions onto a set of suitably chosen local trial-functions with subsequent orthonormalization. The particular nature of the local orbitals in FPLO make them an ideal set of projectors, since they are constructed to be a chemical basis. While in many cases projection onto the FPLO basis orbitals is sufficient, the option is there to choose particular local linear combinations as projectors, in order to treat cases of bond centered Wannier functions. This choice turns out to lead to highly localized Wannier functions, which obey the space group symmetry of the crystal by construction. Furthermore we discuss the interplay of the Berry connection and position operator and especially its possible approximation, symmetries and the optimal choice of Bloch sum phase gauge in cases where the basis is not explicitly known. We also introduce various features which are accessible via the FPLO implementation of SCMPWFs, discuss and compare performance and provide example applications.

description: A random search process in a networked environment is governed by the time it takes to visit every node, termed the cover time. Often, a networked process does not proceed in isolation but competes with many instances of itself within the same environment. A key unanswered question is how to optimise this process: how many concurrent searchers can a topology support before the benefits of parallelism are outweighed by competition for space? Here, we introduce the searcher-averaged parallel cover time (APCT) to quantify these economies of scale. We show that the APCT of the networked symmetric exclusion process is optimised at a searcher density that is well predicted by the spectral gap. Furthermore, we find that non-equilibrium processes, realised through the addition of bias, can support significantly increased density optima. Our results suggest novel hybrid strategies of serial and parallel search for efficient information gathering in social interaction and biological transport networks.

description: The Project 8 collaboration aims to measure the absolute neutrino mass or improve on the current limit by measuring the tritium beta decay electron spectrum. We present the current distributed computing model for the Project 8 experiment and requirements for future phases. Project 8 is in its second phase of data taking with a near continuous data rate of 1Gbps. The current computing model uses DIRAC (Distributed Infrastructure with Remote Agent Control) for its workflow and data management. A detailed meta-data assignment using the DIRAC File-Catalog is used to automate raw data transfers and subsequent stages of data processing. The DIRAC system is deployed on containers managed using a Kubernetes cluster to provide a scalable infrastructure. A modified DIRAC Site Director provides the ability to submit jobs using singularity on opportunistic High-Performance Computing sites.

description: Observations at 70 microns with the Spitzer Space Telescope have detected several stellar systems within 65 pc of the Sun. Of 18 presumably young systems detected in this study, as many as 15 have 70-micron emission in excess of that expected from their stellar photospheres. Five of the systems with excesses are members of the Tucanae Association. The 70-micron excesses range from a factor of ~2 to nearly 30 times the expected photospheric emission from these stars. In contrast to the 70-micron properties of these systems, there is evidence for an emission excess at 24 microns for only HD 3003, confirming previous results for this star. The lack of a strong 24-micron excess in most of these systems suggests that the circumstellar dust producing the IR excesses is relatively cool (T_dust < 150 K) and that there is little IR-emitting material within the inner few AU of the primary stars. Many of these systems lie close enough to Earth that the distribution of the dust producing the IR excesses might be imaged in scattered light at optical and near-IR wavelengths.

description: Belle II has started the Phase 3 data taking with a fully quipped detector. The data flow at the maximum luminosity is expected to be 12PB of data/year and will be analysed by a cutting-edge computing infrastructure spread over 26 Countries. Some of the major Computing Centres for HEP in Europe, USA and Canada will store and tackle the second copy of RAW data. In this scenario, the international Network Infrastructure for Research plays a key role in supporting and orchestrating all the activities of data analysis and replication. The large-scale data challenge will also take advantage form LHCONE VRF service and the support of Network experts of KEKCC, Belle II sites and NREN. The program of major upgrade in 2019 massively empowered the connection among Japan, Europe and USA over a 100Gb geographic ring. In this work, we summarize the network requirements needed to accomplish all the tasks provided by the computing model. We also highlight the status of the major network links that support and advance Belle II. Lastly, we present the results of the last Network Data Challenge campaign performed between KEK and the main RAW Data centres with the additional usage of the Data Transfer Node service provided by GEANT.

description: Chameleon scalar fields can screen their associated fifth forces from detection by changing their mass with the local density. These models are an archetypal example of a screening mechanism, and have become an important target for both cosmological surveys and terrestrial experiments. In particular there has been much recent interest in searching for chameleon fifth forces in the laboratory. It is known that the chameleon force is less screened around non-spherical sources, but only the field profiles around a few simple shapes are known analytically. In this work we introduce a numerical code that solves for the chameleon field around arbitrary shapes with azimuthal symmetry placed in a spherical vacuum chamber. We find that deviations from spherical symmetry can increase the chameleon acceleration experienced by a test particle by up to a factor of $\sim 3$, and that the least screened objects are those which minimize some internal dimension.

description: In this paper, we use a simple discrete dynamical model to study integer partitions and their lattice. The set of reachable configurations of the model, with the order induced by the transition rule defined on it, is the lattice of all partitions of an integer, equipped with a dominance ordering. We first explain how this lattice can be constructed by an algorithm in linear time with respect to its size by showing that it has a self-similar structure. Then, we define a natural extension of the model to infinity, which we compare with the Young lattice. Using a self-similar tree, we obtain an encoding of the obtained lattice which makes it possible to enumerate easily and efficiently all the partitions of a given integer. This approach also gives a recursive formula for the number of partitions of an integer, and some informations on special sets of partitions, such as length bounded partitions.

We proposed a novel solution to the problem of correcting label pairwise ensembles. The main step of the correction procedure is to compute classifier-specific competence and cross-competence measures, which estimates error pattern of the underlying classifier. At the fusion phase we employed two weighting approaches based on information theory. The classifier weights promote base classifiers which are the most susceptible to the correction based on the fuzzy confusion matrix. During the experimental study, the proposed approach was compared against two reference methods. The comparison was made in terms of six different quality criteria. The conducted experiments reveals that the proposed approach eliminates one of main drawbacks of the original FCM-based approach i.e. the original approach is vulnerable to the imbalanced class/label distribution. What is more, the obtained results shows that the introduced method achieves satisfying classification quality under all considered quality criteria. Additionally, the impact of fluctuations of data set characteristics is reduced.

description: We offer an alternative to the conventional network formulation of quantum computing. We advance the analog approach to quantum logic gate/circuit construction. As an illustration, we consider the spatially extended NOT gate as the first step in the development of this approach. We derive an explicit form of the interaction Hamiltonian corresponding to this gate and analyze its properties. We also discuss general extensions to the case of certain time-dependent interactions which may be useful for practical realization of quantum logic gates.

description: Urbanization is an inevitable trend of economic development. It is an important indicator that reflects the industrialization and modernization of a country. In the long-term urbanization process in China, due to the excessive emphasis on the status of the city and one-sided emphasis on urban development, a serious of urban diseases such as population congestion and environmental damage have been caused. Meanwhile, neglected rural areas have exposed social problems such as aging and hollowing out, making the urban-rural dual structure more prominent. Currently, China’s economic and social development has reached a new stage, and the realization of urban-rural integration is a major measure to comprehensively develop the national economy and social undertakings. Vigorously developing the rural areas and revitalizing the countryside has become a national policy. Traditional ancient villages are treasures in the vast rural areas. They should be more protected and developed to eliminate the urban-rural gap, thereby passing down and carrying forward the essence of traditional culture and enhancing China’s national confidence and cultural confidence. Focusing on the protection and planning of ancient villages, combined with the current policy background of new urbanization, based on field research on Mingkou Village, Leping City, Jiangxi Province, protective development strategies are put forward for ancient villages and their water management from the perspective of water management in ancient villages to arouse people’s attention to the protection of ancient villages.

description: We propose a new unfolding scheme to analyze energy spectra of complex large-scale systems which are inherently of multi-periodicity. Considering twisted bilayer graphene (tBLG) as an example, we first show that the conventional unfolding scheme in the past using a single primitive-cell representation causes serious problems in analyses of the energy spectra. We then introduce our multi-space representation scheme in the unfolding method and clarify its validity for tBLG. Velocity renormalization of Dirac electrons in tBLG is elucidated in the present unfolding scheme.

Evaluation of navicular syndrome horses with magnetic resonance imaging to identify structures involved, prevalence and location of injury, and evaluation of a surgical approach for transection of the collateral sesamoidean ligament

Subjects: Horses -- Diseases

description: The first goal of this study was to develop optimal, standardized magnetic resonance imaging protocols for the foot of the horse using a 1 Tesla magnet. The optimal magnetic resonance imaging evaluation was determined to contain proton density, T2-weighted, short tau inversion recovery, and gradient echo sequences in axial, sagittal, and coronal image planes. This enabled detailed examination of the front feet of horses with lameness localized to this area. The second goal of this study was to examine horses with recent and chronic onset of navicular syndrome to test the hypothesis that the pathologic changes found in the feet of these two groups of horses would be similar when evaluated with magnetic resonance imaging. These results provided evidence that the location, severity, and prevalence of structures affected is different in these two groups of horses and determinations could be made as to the likelihood of specific pathology based on the specific group the horse was in. The horses with chronic signs of navicular disease had an increased likelihood of having multiple structures affected within the foot and the overall prevalence of injury to each structure was increased. The third goal of this study was to determine if a surgical treatment involving desmotomy of the collateral sesamoidean ligament in normal horses could be a viable treatment option for use in horses with navicular syndrome that were clinically affected with pathologic change in this ligament. This surgical procedure did not cause long term lameness in normal horses and was determined to be a possible treatment option for horses clinically affected with pathologic change in the collateral sesamoidean ligament.

description: Metallic nanowires are known to break into shorter fragments due to the Rayleigh instability mechanism. This process is strongly accelerated at elevated temperatures and can completely hinder the functioning of nanowire-based devices like e.g. transparent conductive and flexible coatings. At the same time, arranged gold nanodots have important applications in electrochemical sensors. In this paper we perform a series of annealing experiments of gold and silver nanowires and nanowire junctions at fixed temperatures 473, 673, 873 and 973 K (200, 400, 600 and 700 °C) during a time period of 10 minutes. We show that nanowires are especially prone to fragmentation around junctions and crossing points even at comparatively low temperatures. The fragmentation process is highly temperature dependent and the junction region breaks up at a lower temperature than a single nanowire. We develop a gold parametrization for Kinetic Monte Carlo simulations and demonstrate the surface diffusion origin of the nanowire junction fragmentation. We show that nanowire fragmentation starts at the junctions with high reliability and propose that aligning nanowires in a regular grid could be used as a technique for fabricating arrays of nanodots.

description: We describe the dataset of very rare events recorded by the OPERA experiment. Those events represent tracks of particles associated with tau neutrinos emerged from a pure muon neutrino beam, due to neutrino oscillations. The OPERA detector, located in the underground Gran Sasso Laboratory, consisted of an emulsion/lead target with an average mass of about 1.2 kt, complemented by the electronic detectors. It was exposed, from 2008 to 2012, to the CNGS (CERN Neutrinos to Gran Sasso) beam, an almost pure muon neutrino beam with a baseline of 730 km, collecting a total of $17.97 \times 10^{19}$ protons on target. The OPERA Collaboration eventually assessed the discovery of $\nu_{\mu} \rightarrow \nu_{\tau}$ oscillations with a significance of 6.1 $\sigma$ by observing ten $\nu_{\tau}$ candidates. These events have been published at CERN Open Data Portal.

description: Density estimation is a central task in statistics and machine learning. This problem aims to determine the underlying probability density function that best aligns with an observed data set. Some of its applications include statistical inference, unsupervised learning, and anomaly detection. Despite its relevance, few works have explored the application of quantum computing to density estimation. In this article, we present a novel quantum-classical density matrix density estimation model, called Q-DEMDE, based on the expected values of density matrices and a novel quantum embedding called quantum Fourier features. The method uses quantum hardware to build probability distributions of training data via mixed quantum states. As a core subroutine, we propose a new algorithm to estimate the expected value of a mixed density matrix from its spectral decomposition on a quantum computer. In addition, we present an application of the method for quantum-classical anomaly detection. We evaluated the density estimation model with quantum random and quantum adaptive Fourier features on different data sets on a quantum simulator and a real quantum computer. An important result of this work is to show that it is possible to perform density estimation and anomaly detection with high performance on present-day quantum computers.
