Longitudinal Internal Validity of the Quality of Life after Brain Injury: Response Shift and Responsiveness

The Quality of Life after Brain Injury (QoLIBRI) questionnaire was developed and validated to assess disease-specific health-related quality of life (HRQoL) in individuals after TBI. The present study aims to determine its longitudinal validity by assessing its responsiveness and response shift from 3 to 6 months post-injury. Analyses were based on data from the European longitudinal observational cohort Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury study. A total of 1659 individuals recovering from TBI were included in the analyses. Response shift was assessed using longitudinal measurement invariance testing within the confirmatory factor analyses framework. Responsiveness was analyzed using linear regression models that compared changes in functional recovery as measured by the Glasgow Outcome Scale–Extended (GOSE) with changes in the QoLIBRI scales from 3 to 6 months post-injury. Longitudinal tests of measurement invariance and analyses of discrepancies in practical significance indicated the absence of response shift. Changes in functional recovery status from three to six months were significantly associated with the responsiveness of the QoLIBRI scales over the same time period. The QoLIBRI can be used in longitudinal studies and is responsive to changes in an individual’s functional recovery during the first 6 months after TBI.
Ion-Doped Calcium Phosphate-Based Coatings with Antibacterial Properties

Ion-substituted calcium phosphate (CP) coatings have been extensively studied as promising materials for biomedical implants due to their ability to enhance biocompatibility, osteoconductivity, and bone formation. This systematic review aims to provide a comprehensive analysis of the current state of the art in ion-doped CP-based coatings for orthopaedic and dental implant applications. Specifically, this review evaluates the effects of ion addition on the physicochemical, mechanical, and biological properties of CP coatings. The review also identifies the contribution and additional effects (in a separate or a synergistic way) of different components used together with ion-doped CP for advanced composite coatings. In the final part, the effects of antibacterial coatings on specific bacteria strains are reported. The present review could be of interest to researchers, clinicians, and industry professionals involved in the development and application of CP coatings for orthopaedic and dental implants.
Improved 3D Shallow‐Deep Vs Structure in Tongzhou, Beijing (China), Revealed by Dense Array Ambient Noise Tomography

Shear‐wave velocity (Vs) structures can reveal the shallow sediment thickness and deep tectonic features of buried faults and geological units. They are important for reducing seismic and geological disasters in urban areas. Based on ambient noise data from the Tongzhou dense array (919 seismographic stations), we obtain a fine shallow‐deep (0–5 km) 3D Vs model, by jointly inverting the phase‐velocity dispersions of Rayleigh waves, including short‐period (0.3–2 s) multimode dispersions using the frequency‐Bessel transform method and the long‐period (2–6 s) fundamental‐mode dispersions using the fast marching method. Our results show that the Vs inhomogeneities agree well with the distribution of geological units. We use the 1 km/s isodepth of Vs as the reference thickness of quaternary sediments. Fengbo sag (FBS) and Dachang sag (DCS), which mainly show low velocity and density, have thick sediment thicknesses (approximately 550–600 and 320–420 m, respectively). The NE high‐velocity belt in Daxing high (DXH) has a thinner sediment thickness (∼230 m). Thus, FBS and DCS have a greater risk of earthquake hazards owing to the strong amplification effects of ground motion. Additionally, Vs distribution in the FBS, DCS, DXH, and Yanshan Fold Belt are spatially related to the medium density and buried faults (Nanyuan‐Tongxian, Daxing, and Xiadian faults). We infer that the Vs structures are associated with the controlling effects of these large normal faults and inhomogeneous strata density. The discontinuity of the NE high‐velocity belt in DXH probably results from the intense tectonic activity of Nankou‐Sunhe fault.
(Definite) denotation and case

Recent minimalist approaches have reduced case to independent primitives (agreement, Tense) – but without any connection to its morphological expression. To solve this dichotomy, we consider the Latin -s case ending. Rejecting default treatments, we conclude that -s is associated with denotational, operator properties. These can be read as the set forming operator i.e. plural; as the inclusion operator, i.e. partitive, possessor, etc. (in a word ‘oblique’); or as the quantificational closure of EPP contexts (‘nominative’). These properties are preserved in the two-case declension of medieval Gallo-Romance, and in its residues in Romansh varieties. Thus so-called case is a denotational, ‘determiner-like’ element, with consequences for the classical historical correlation between loss of Latin case and development of the Romance determiner system.
In Vitro Killing Activities of Anidulafungin and Micafungin with and without Nikkomycin Z against Four Candida auris Clades

Candida auris is a multidrug-resistant pathogen against which echinocandins are the drug of choice. However, information on how the chitin synthase inhibitor nikkomycin Z influences the killing activities of echinocandins against C. auris is currently lacking. We determined the killing activities of anidulafungin and micafungin (0.25, 1, 8, 16 and 32 mg/L each) with and without nikkomycin Z (8 mg/L) against 15 isolates representing four C. auris clades (South Asian n = 5; East Asian n = 3; South African n = 3; South American n = 4, two of which were of environmental origin). Two and one isolates from the South Asian clade harbored mutations in the hot-spot 1 (S639Y and S639P) and 2 (R1354H) regions of the FKS1 gene, respectively. The anidulafungin, micafungin and nikkomycin Z MIC ranges were 0.015-4, 0.03-4 and 2->16 mg/L, respectively. Anidulafungin and micafungin alone exerted weak fungistatic activity against wild-type isolates and the isolate with a mutation in the hot-spot 2 region of FKS1 but was ineffective against the isolates with a mutation in the hot-spot 1 region. The nikkomycin Z killing curves were always similar to their respective controls. Twenty-two of sixty (36.7%) anidulafungin plus nikkomycin Z and twenty-four of sixty (40%) micafungin plus nikkomycin Z combinations produced at least 100-fold decreases in the CFUs (synergy), with a 41.7% and 20% fungicidal effect, respectively, against wild-type isolates. Antagonism was never observed. Similar results were found with the isolate with a mutation in hot-spot 2 of FKS1, but the combinations were ineffective against the two isolates with prominent mutations in hot-spot 1 of FKS1. The simultaneous inhibition of β-1,3 glucan and chitin synthases in wild-type C. auris isolates produced significantly greater killing rates than either drug alone. Further studies are warranted to verify the clinical efficacy of echinocandin plus nikkomycin Z combinations against echinocandin susceptible C. auris isolates.
Resolución del problema dinámico directo de cadenas abiertas utilizando las ecuaciones de Gibbs-Appell

In this work is described a novel method to solve the direct dynamic problem of robots manipulators based on the Gibbs Appell equations of the dynamics. The method is based on the obtaining of the system inertia matrix by means of the Gibbs function hessian. To obtain this matrix, an efficient O(n2) recursive algorithm in tensor notation is proposed, which is used in the elaboration of a FORTRAN program, with this program the movement of a robot PUMA is simulated. The simulation results are compared with those other well-known methods results.
An In-Band Full-Duplex Low Noise Amplifier Integrated With an Electrical Balance Duplexer Without Explicit Matching

This letter presents a low noise amplifier (LNA) integrated with an electrical-balance duplexer (EBD) for in-band full duplex operation in a 65-nm bulk CMOS process. A simultaneous noise and input matching (SNIM) structure consisting of a large transistor and hybrid transformer for EBD is proposed. The proposed structure does not require an additional matching circuit between the LNA and the antenna (ANT). Furthermore, the use of a large transistor in the SNIM helps minimize the noise figure (NF). The core size of this LNA is $0.86\times0.33$ mm2. The measurement results show 14.6–16.5 dB ANT-RX (receiver) gain, 4.29–4.53 dB TX-ANT loss, 30.6–34.5 dB isolation, and 5.33–5.37 dB NF. The LNA has an input 1-dB compression point (IP1dB) of −18.1 dBm at 15 GHz and the power consumption is 22 mW.
Simultaneous Scatterer Shape Estimation and Partial Aperture Far-Field Pattern Denoising

We study the inverse problem of recovering the scatterer shape from the far-field pattern(FFP) in the presence of noise. Furthermore, only a discrete partial aperture is usually known. This problem is ill-posed and is frequently addressed using regularization. Instead, we propose to use a direct approach denoising the FFP using a filtering technique. The effectiveness of the technique is studied on a scatterer with the shape of the ellipse with a tower. The forward scattering problem is solved using the finite element method (FEM). The numerical FFP is additionally corrupted by Gaussian noise. The shape parameters are found based on a least-square error estimator. If ũ∞ is a perturbation of the FFP then we attempt to find Γ, the scatterer shape, which minimizes ‖ u∞−ũ∞ ‖ using the conjugate gradient method for the denoised FFP.

Development of an Immersive Virtual Colonoscopy Viewer for Colon Growths Diagnosis

Desktop-based virtual colonoscopy has been proven to be an asset in the identification of colon anomalies. The process is accurate, although time-consuming. The use of immersive interfaces for virtual colonoscopy is incipient and not yet understood. In this work, we present a new design exploring elements of the VR paradigm to make the immersive analysis more efficient while still effective. We also plan the conduction of experiments with experts to assess the multi-factor influences of coverage, duration, and diagnostic accuracy.
A Test Point Selection Method Based on Fault Response Matrices Framework

This article presents a novel method for test point selection based on the fault response matrices (FR matrices) framework. The main purpose of this method is to minimize the set of test points by constructing a FR matrices framework, to resolve fault effects vanishing and fault detection (FD) degradation, and to achieve fewer test point set and higher fault coverage. According to the analysis of the FR matrices and their derived matrices, the efficiency of the response of each node on the fault is ranked and a new propagation cone for undetectable faults is defined to narrow the candidate test point set. We propose a custom testability measure to evaluate the impact of candidate test points on design and obtain an optimal configuration of the most efficient test points accurately and rapidly. This methodology fully considers the correlation among test points, faults, and test vectors across internal signals resolving timing constraints to increase faults coverage. It can narrow the hard-to-test areas of random test patterns and reduce the test vector set volume of deterministic test patterns. Our experimental results demonstrate the superiority of the proposed method: higher test coverage; minimum test time; fewer deterministic test patterns; and smaller hardware overhead.
Transmembrane Protein Inter-Helical Residue Contacts Prediction Using Transductive Support Vector Machines

Protein functions are strongly related to their 3D structure. Therefore, it is crucial to identify their structure to understand how they behave. Studies have shown that numerous numbers of proteins cross a biological membrane, called Transmembrane (TM) proteins, and many of them adopt alpha helices shape. Unlike the current contact prediction methods that use inductive learning to predict transmembrane protein inter-helical residues contact, we adopt a transductive learning approach. The idea of transductive learning can be very useful when the test set is much bigger than the training set, which is usually the case in amino acids residues contacts prediction. We test this approach on a set of transmembrane protein sequences to identify helix-helix residues contacts, compare transductive and inductive approaches, and identify conditions and limitations where TSVM outperforms inductive SVM. In addition, we investigate the performance degradation of the traditional TSVM and explore the proposed solutions in the literature. Moreover, we propose an early stop technique that can outperform the state of art TSVM and produce a more accurate prediction.
Comparison of Ten Metal-Doped LaFeO3 Samples on Photocatalytic Degradation of Antibiotics in Water under Visible Light: Role of Surface Area and Aqueous Phosphate Ions

Doping semiconducting oxides, such as LaFeO3 (LF), with metallic elements is a good strategy to improve the performance of photocatalysts. In this study, LF and ten different nanopowders metal-doped at the La or Fe site of LaFeO3 were evaluated in the photocatalytic degradation of ciprofloxacin (CP) and oxytetracycline (OTC). The following metals were used in the doping (mol%) process of LF: Pd 3% and 5%; Cu 10%; Mg 5%, 10%, and 20%; Ga 10%; Y 10% and 20%; and Sr 20%. The doped samples were synthetized using a citrate auto-combustion technique. From the X-ray diffraction (XRD) data, only a single crystalline phase, namely an orthorhombic perovskite structure, was observed except for trace amounts of PdO in the sample with Pd 5%. The specific surface area (SSA) ranged from 9 m2 g−1 (Ga 10%) to 20 m2 g−1 (Mg 20%). SEM images show that all samples were constituted from agglomerates of particles whose sizes ranged from ca. 20 nm (Mg 20%) to ca. 100 nm (Pd 5%). Dilute aqueous solutions (5 × 10−6 M) prepared for both CP and OTC were irradiated for 240 min under visible-light and in the presence of H2O2 (10−2 M). The results indicate a 78% removal of OTC with Cu 10% doped LF in a phosphate buffer (pH = 5.0). The degradation of CP is affected by pH and phosphate ions, with 78% (in unbuffered solution) and 54% (in phosphate buffer, pH = 5.0) removal achieved with Mg 10% doped LF. The reactions follow a pseudo-first order kinetic. Overall, this study is expected to deepen the assessment of photocatalytic activity by using substrates with different absorption capacities on photocatalysts.
Directional exciton-polariton photoluminescence emission from terminals of a microsphere-coupled organic waveguide

We report on angle-resolved, exciton-polariton photoluminescence measurements from asymmetric terminals of a microsphere-coupled organic waveguide (MOW). The MOW architecture consisted of a SiO2 microsphere coupled with a diaminoanthroquinone mesowire, self-assembled on a glass substrate. The angle-resolved emission measurements were performed using spatially filtered Fourier-plane optical imaging method. The light emanating from the sphere-terminus had two regions of angular emission in the Fourier-plane, of which one had azimuthal angular spread as small as 10°. The emission from wire terminus was uni-directional in nature, with some light emitted beyond the critical angle of glass-air interface. Our results highlight unique directional emission characteristics of a hybrid organic waveguide geometry and may have implications on single-element, exciton-polariton based light-emitting devices and lasers.
A coarse grid generation algorithm for agglomeration multigrid method on unstructured grids

A new agglomeration algorithm to generate coarse grids for multigrid methods on unstructured and hybrid grids is proposed in this paper. The algorithm, which we call a global coarsening algorithm, is based on the edge coloring of the grids so that it can agglomerate any type of grids. The agglomeration procedure is automatic and generates a globally optimum shape in contrast to the conventional greedy-type frontal algorithm. The method is applied to compute the 2D/3D Euler and 2D Navier-Stokes equations on triangular, tetrahedral and hybrid meshes, respectively. The present agglomeration multigrid method shows better convergence than the existing method owing to the better quality of the coarse grids.
A second look at inference for bivariate Skellam distributions

Two bivariate extensions of the Skellam distribution were introduced in 2014 by a subset of the present authors, who also proposed moment estimators for the dependence parameters in these models. The limiting distribution of these estimators is established here, and their asymptotic efficiency is compared with that of the corresponding maximum likelihood estimators. © 2017 The Authors.

Creative Arts Therapy for Healthcare Professionals Is Associated With Long-Term Improvements in Psychological Distress

Reducing the levels of psychological distress symptoms in healthcare workers is one of the most important points of current healthcare management. Sustained improvement of psychological distress of healthcare workers is a result rarely seen in behavioral intervention. Creative arts intervention for healthcare workers is both feasible and cost-effective. Objective Burnout in healthcare professionals (HCPs) is a pressing issue in healthcare. We report the long-term impact of our previous creative arts therapy (CAT) intervention for reducing psychological distress in HCPs. Methods Healthcare professionals were randomized to CAT intervention or control group. The CAT group completed surveys evaluating symptoms of psychological distress at 4 months, 8 months, and 1 year postintervention, whereas the control group completed surveys at the 1-year mark. Results The CAT group demonstrated sustained improvement in distress scores for anxiety, depression, and affect at 4 and 8 months postintervention. At the 12-month mark, the CAT group exhibited improvements in anxiety, depression, and affect compared with the control group. Conclusion Creative arts therapy has lasting benefits for HCPs. Long-term follow-ups are crucial for assessing sustainability, and further investigation should focus on disseminating and implementing CAT programs for HCPs.
extendGAN+: Transferable Data Augmentation Framework Using WGAN-GP for Data-Driven Indoor Localisation Model

For indoor localisation, a challenge in data-driven localisation is to ensure sufficient data to train the prediction model to produce a good accuracy. However, for WiFi-based data collection, human effort is still required to capture a large amount of data as the representation Received Signal Strength (RSS) could easily be affected by obstacles and other factors. In this paper, we propose an extendGAN+ pipeline that leverages up-sampling with the Dirichlet distribution to improve location prediction accuracy with small sample sizes, applies transferred WGAN-GP for synthetic data generation, and ensures data quality with a filtering module. The results highlight the effectiveness of the proposed data augmentation method not only by localisation performance but also showcase the variety of RSS patterns it could produce. Benchmarking against the baseline methods such as fingerprint, random forest, and its base dataset with localisation models, extendGAN+ shows improvements of up to 23.47%, 25.35%, and 18.88% respectively. Furthermore, compared to existing GAN+ methods, it reduces training time by a factor of four due to transfer learning and improves performance by 10.13%.
Simulation and Analysis of a Biconical Antenna and Pyramidal Horn Antenna Using EMCoS VLab

As the world delves further and farther into the future, the presence of antennas will be more and more crucial in its development. As of the present, there are already numerous applications seen for the antenna. Ever since its creation, it was already obvious that it would leapfrog the boundaries of communication and push towards a more interconnected and capable form of society where data flows freely. This paper focuses on the two specific types of antenna and their specific capabilities, the Biconical antenna, and the pyramidal horn antenna. The paper will take a look at the parameters and restrictions surrounding them such as the impedance, and current and also delve into the numerous applications these antennas can work in. The radiation pattern will be displayed, and both antennas will be compared and contrasted to make known the advantages and disadvantages of each antenna. The simulations will be done in software called the EMCos Antenna Vlab, which allows the setting of parameters all well as the simulation itself.
Label Propagation and Quadratic Criterion

Various graph-based algorithms for semi-supervised learning have been proposed in the recent literature. They rely on the idea of building a graph whose nodes are data points (labeled and unlabeled) and edges represent similarities between points. Known labels are used to propagate information through the graph in order to label all nodes. In this chapter, we show how these different algorithms can be cast into a common framework where one minimizes a quadratic cost criterion whose closed-form solution is found by solving a linear system of size n (total number of data points). The cost criterion naturally leads to an extension of such algorithms to the inductive setting, where one obtains test samples one at a time: the derived induction formula can be evaluated in O(n) time, which is much more efficient than solving again exactly the linear system (which in general costs O(kn2) time for a sparse graph where each data point has k neighbors). We also use this inductive formula to show that when the similarity between points satisfies a locality property, then the algorithms are plagued by the curse of dimensionality, with respect to the dimensionality of an underlying manifold.
Some Properties of Inflated Binomial Distribution

The role of binomial distribution in the probability theory and its applications is well known. Recently M. P. Singh [4] has been discussing the socalled inflated binomial distribution. This distribution was introduced for situations which are described by simple binomial except for zero cell which is inflated, that is, there more observations than can be expected on the basis of simple binomial. The investigation of this inflated binomial distribution seems to be useful.
Reliability of a Cluster of Duplicated Computer Systems with the Criticality of Functional Requests to Waiting

High reliability and fault tolerance of computer systems at high performance and low delays of executing the required functions are achieved by consolidating the data processing and storage resources through the use of cluster systems. Ensuring the reliability of cluster architecture computer systems while accelerating their reconfiguration after failures is accompanied by replication and migration of virtual machines. A approach is proposed for the justification of building a computer system with a cluster architecture, composed of duplicated computer nodes. Studies aimed at increasing the readiness of the cluster to timely execution of real-time requests while ensuring a stationary service traffic mode have been carried out. The work of duplicate nodes in load balancing mode and duplicate calculations is considered. In the first mode, requests are evenly distributed among the functional nodes (servers). In the second mode, replicas of the request are created, each of which is executed on one node of the backup system. For control, the calculation results are compared at check points. If there is a mismatch, a repeat calculation is possible.
