Causal Attributions and Perceived Severity as Predictors of Posttraumatic Stress Symptoms after a First Myocardial Infarction

Recent meta-analyses have shown a significant link between symptoms of anxiety and depression, and cardio-vascular diseases (CVDs). The presence of these symptoms has a direct impact on the course and the recovery from the CVDs. A less analyzed aspect is the role played by the stress induced by the onset of CVDs conditions and, especially, by acute myocardial infarction (AMI). In this study, we assessed posttraumatic stress symptoms (PTSS), emotional state, health habits, and subjective perception of the event and causal attributions regarding the infarct, in a sample of 76 patients who had suffered an AMI in the previous 48-72 hours. Structural equation analyses and path analyses showed that the severity of PTSS was predicted by the perceived severity of the AMI and by two specific beliefs (i.e., considering that the AMI is a hereditary condition and that the help of others will not be beneficial). The results suggest the possibility of early identification of patients with a higher risk of suffering a high level of stress derived from the AMI. Based on this evidence, we discuss the possibilities of making effective interventions to reduce these symptoms, often ignored in clinical practice, and improve the medical and psychological prognosis of people with AMI.
Widely tunable S-band fiber-ring lasers and broadband amplified spontaneous emission sources with thulium-doped fluoride fibers

This paper reports our investigation on widely tunable fiber-ring lasers and broadband amplified spontaneous emission (ASE) light sources with thulium-doped fluoride fibers (TDFs). The experimental results for thulium-doped optical fiber amplifiers will also be discussed. We achieved widely tunable fiber lasers that had tuning ranges of 94 nm with 1550 nm + 1050 nm pump configurations and of 85 nm with 1550 nm + 1400 nm pump configurations, respectively. It was observed that the lasers oscillated under multilongitudinal-mode operation with linewidth of 400 MHz, signal-to-source noise ratio of 60 dB, and power stability of 0.003 dB for a laser output of 1 mW. A broadband ASE source with a power density of more than -15 dBm/nm between 1465 and 1535 nm was also demonstrated with a novel hybrid configuration by using both TDF and erbium-doped fiber.
Frequency Domain Gaussian Estimation of Temporally Aggregated Cointegrated Systems

This paper discusses the joint estimation of the long run equilibrium coe cients and the parameters governing the short run dynamics of a fully parametric cointegrated system formulated in continuous time.The model allows the stationary disturbances to be generated by a stochastic di erential equation system and for the variables to be a mixture of stocks and flows.We derive a precise form for the exact discrete analogue of the continuous time model in triangular error correction form, which acts as the basis for frequency domain Gaussian estimation of the unknown parameters using discrete time data.We formally establish the order of consistency and the asymptotic sampling properties of such an estimator.The function of the data that estimates the cointegrating parameters is shown to converge at the rate of the sample size to a mixed normal distribution, while that estimating the short run parameters converges at the rate of the square root of the sample size to a limiting normal distribution.
Dietary Effect of Borage (Borago officinalis) Powder on Growth Performance, Immune Response, and Blood Biochemical Parameters in Common Carp (Cyprinus carpio) Juvenile

In this study, the effect of borage (Borago officinalis) powder on juveniles of common carp (Cyprinus carpio) were investigated. The diets contained control (0), 0.5%, 1.5%, and 2.5% of borage powder. The fish with the initial average weight of 8.40 ± 1.37 were allotted to 12 circular tanks of 300 L capacity at a density of ten fish per each tank and fed to apparent satiety three times a day. The growth performance of the fish showed no significant difference compared to the control group (P > 0.05). By adding 1.5% borage powder to the control diet the mucosal immunity of fish in terms of lysozyme activity (14.26%), total protein (69.64%), immunoglobulin (30.78%), and humoral immunity in term of lysozyme activity (9.7%), complement components C3 (8.27%), C4 (21.64%), and total protein (9.33%) were increased significantly (P < 0.05). A total number of red blood cell (12.39%), mean corpuscular volume (MCV, 8.99%), mean corpuscular hemoglobin (MCH, 10.22%), and hemoglobin (2.69%) showed a significant increase in the fish fed supplemented diet with 1.5% borage powder compared to the control (P < 0.05). The results showed supplemented diet with 1.5% dietary borage powder induced high immunity and survival rate of juvenile common carp.
Garlic essential oil shows no antiviral effects on the replication of HSV-1 in the virus-infected VERO cells

Allium sativum L. has long been used in folk medicine in many countries to treat various ailments (Majewski et al., 2014; El-Saber Batiha et al., 2020). Garlic was also found to exert virucidal activity against herpes simplex virus type 1 (HSV-1), herpes simplex virus type 2 (HSV2), parainfluenza virus type 3 (HPIV-3), vaccinia virus (VV), vesicular stomatitis virus (VSV), and human rhinovirus type 2 (HRV-2). Unfortunately, concentrations that were virucidal were also toxic to HeLa and VERO cells (Weber, 1992). The constituents responsible for the virucidal effect of garlic in the order of decreasing activity were found to be: ajoene, allicin, allyl methyl thiosulfinate, and methyl allyl thiosulfinate (Weber et al., 1992). Fresh garlic bulbs extract was shown to inhibit influenza virus A/H1N1 propagated in MDCK cells, reducing hemagglutinin (HA) titer, CPE induction, and viral RNA (Mehrbod, 2009). Ajoene was shown to inhibit early events of viral replication, particularly virus adsorption, of HIV-1 (Walder et al., 1997). However, garlic and garlic supplements require special attention when used in HIV-infected patients, since serious interactions were reported with anti-HIV drugs, ex. saquinavir (James, 2001). As it was mentioned above, garlic was found to exert virucidal activity against Herpesviruses, but little is known about the influence of garlic on the replication of those viruses inside the infected cells. That is why the purpose of our research was to evaluate the antiviral potential of garlic essential oil against HSV-1 replicating in VERO cells. The cytotoxicity was evaluated against VERO (ECACC, No. 84113001) cells and for comparison, the human hypopharyngeal cancer cell line FaDu (ATCC, HTB-43).
NIMROD Resistive Magnetohydrodynamic Simulations of Spheromak Physics

The physics of spheromak plasmas is addressed by time-dependent, three-dimensional, resistive magneto-hydrodynamic simulations with the NIMROD code. Included in some detail are the formation of a spheromak driven electrostatically by a coaxial plasma gun with a flux-conserver geometry and power systems that accurately model the Sustained Spheromak Physics Experiment (SSPX) (R. D. Wood, et al., Nucl. Fusion 45, 1582 (2005)). The controlled decay of the spheromak plasma over several milliseconds is also modeled as the programmable current and voltage relax, resulting in simulations of entire experimental pulses. Reconnection phenomena and the effects of current profile evolution on the growth of symmetry-breaking toroidal modes are diagnosed; these in turn affect the quality of magnetic surfaces and the energy confinement. The sensitivity of the simulation results address variations in both physical and numerical parameters, including spatial resolution. There are significant points of agreement between the simulations and the observed experimental behavior, e.g., in the evolution of the magnetics and the sensitivity of the energy confinement to the presence of symmetry-breaking magnetic fluctuations.
A test of the frozen-flux approximation using a new geodynamo model

The physics underlying the frozen–flux approximation is reviewed. Recent high–resolution geodynamo simulations, described here for the first time, afford opportunities of testing the approximation, and the results from a very simple test are reported. This consists in evaluating the unsigned flux of magnetic field from the core at three successive epochs separated by about 150 years, and in showing that this changes by only ca.3% in the intervals between the epochs. Because of the smallness of this change, which is created by the electromagnetic diffusion excluded in the frozen–flux approximation but present in the simulations, we argue that the approximation is useful in analogous analyses of the geomagnetic field over similar time–scales.
Topology Optimization of Heat and Mass Transfer Problems: Laminar Flow

The design of efficient structures for heat and mass transfer problems involves the implementation of an appropriate topology optimization strategy in order to fully take into account the bi-objective nature of the problem. This article couples the finite-volume method (FVM), for the direct solver, with the discrete adjoint approach, for the sensitivity analysis, in order to tackle both fluid dynamic and heat transfer optimization in the frame of laminar flows. Details are provided about the sparsity pattern of the discrete adjoint system, which requires special attention to select a suitable matrix iterative solver. Several examples underline the adequacy of topology optimization in conjunction with the FVM for the minimization of the power dissipated by the fluid. Then, a bi-objective problem aiming at minimizing the pressure drop while maximizing the recoverable thermal power is solved by the identification of its Pareto frontier, thanks to an aggregate objective function (AOF) method. The main conclusion deals with the possibility of finding an acceptable trade-off between both objectives and the potential of topology optimization for heat and mass transfer optimization.
Optically Induced Degradation Due to Thermally Activated Diffusion in GaN-Based InGaN/GaN MQW Solar Cells

We extensively investigate the degradation of gallium nitride (GaN)-based high periodicity indium GaN (InGaN)-GaN multiple quantum well (MQW) solar cells submitted to optical stress at high excitation intensity and high temperature. The original results reported in this article indicate the presence of a thermally activated diffusion of impurities from the ${p}$ -side of the devices toward the active region (AR), which favors the increase in the Shockley–Read–Hall (SRH) recombination within the MQWs. Appropriate fitting of the degradation kinetics according to Fick’s second law allowed the extrapolation of the diffusion coefficient of the defect involved in the degradation and of the related activation energy. The obtained values suggest that degradation originates from the diffusion of hydrogen. The proposed analytical methodology and the related results provide insight on MQW solar cells degradation and can be used to increase cell performance and reliability in novel applications and harsh environments.
The signature of an air gun array: Computation from near‐field measurements including interactions

We designed a system to enable the signature of an air gun array to be calculated at any point in the water from a number of simultaneous independent measurements of the near-held pressure held [subject of a patent application]. The number of these measurements must not be less than the number of guns in the array. The underlying assumption in our method is that the oscillating bubble produced by an air gun is small compared with the wavelengths of seismic interest. Each bubble thus behaves as a point source, both in the generation of seismic waves and in its response to incident seismic radiation produced by other nearby bubbles. It follows that the intcraction effects between the bubbles may be described in terms of spherical waves. The array of interacting guns is equivalent to a notional array of noninteracting guns whose combined seismic radiation is identical. The seismic signatures of the equivalent independent elements of this notional array can be determined from the near-held measurements. The seismic radiation pattern emitted by the whole array can be computed from these signatures by linear superposition, with a spherical correction applied. The method is tested by comparing far-field signatures computed in this way with field measurements made in deep water. The computed and measured signatures match each other very closely. By comparison, signatures computed neglecting this interaction are a poor match to the
Bifurcations in dynamical systems with interior symmetry

We propose a definition of interior symmetry in the context of general dynamical systems. This concept appeared originally in the theory of coupled cell networks, as a generalization of the idea of symmetry of a network. The notion of interior symmetry introduced here can be seen as a special form of forced symmetry breaking of an equivariant system of differential equations. Indeed, we show that a dynamical system with interior symmetry can be written as the sum of an equivariant system and a ‘perturbation term’ which completely breaks the symmetry. Nonetheless, the resulting dynamical system still retains an important feature common to systems with symmetry, namely, the existence of flow-invariant subspaces. We define interior symmetry breaking bifurcations in analogy with the definition of symmetry breaking bifurcation from equivariant bifurcation theory and study the codimension one steady-state and Hopf bifurcations. Our main result is the full analogues of the well-known Equivariant Branching Lemma and the Equivariant Hopf Theorem from the bifurcation theory of equivariant dynamical systems in the context of interior symmetry breaking bifurcations.
Colorectal Cancer—The Worst Enemy Is the One We Do Not Know

Background: Colorectal cancer is one of the most common cancers in humans. It is the third most frequently diagnosed malignant neoplasm and is the second highest cause of cancer mortality in the world. Every year, more and more people die of colorectal cancer because the diagnosis is conducted too late. This shows how important a role screening tests and the awareness of the population about the symptoms play in this aspect. This article aimed to determine the knowledge of the Polish population about morbidity, symptoms, prevention, and subjective feelings about the level of availability of knowledge about colorectal cancer. Methods: In 2020, a study was conducted using an online questionnaire assessing the awareness of the Polish population about colorectal cancer. A self-authored questionnaire including questions about socio-demographic characteristics, and 18 questions related to substantive issues, was used. A research group was selected (n = 633). The substantive part of the questionnaire included questions examining the respondents’ knowledge about morbidity, symptoms, prevention, and subjective feelings about the level of availability of knowledge about colorectal cancer. Results: The respondents’ awareness level was influenced by demographic factors, such as gender: (p < 0.05) and age (p < 0.05) and social factors, such as: level of education (p < 0.05) or professional situation (p < 0.05). Compared to thematic articles from other countries, the research group was divided into smaller subgroups due to the abovementioned factors, due to which it was possible to stratify and analyze the significance of differences between them.
Model-Based Distributed Asynchronous Sampling for Multiagent Consensus With Event-Detecting Delays and Network Delays

In this article, the practical average consensus problem of linear multiagent systems with model-based distributed asynchronous sampling is investigated. Both internal event-detecting delays and external network delays are allowed in systems. Data-sampling instants are generated asynchronously by local event-triggering conditions. Particularly, data-sampling instants and event-triggering instants of each agent are also asynchronous due to the existence of event-detecting delays. Prediction models are utilized in detecting events and updating control inputs. Artificial interpolation instants are introduced in each sampling interval to address theoretical challenges brought by internal and external delays. To deal with this kind of complex asynchronous setup with multiple time delays, based on the Barbalat's Lemma, a new procedure for deriving conditions for average consensus and a theoretical analysis approach are presented.
Cognitive-linguistic skills and vocabulary knowledge breadth and depth in children’s L1 Chinese and L2 English

Abstract This study examined the correlates of different aspects of vocabulary knowledge in L1 Chinese and L2 English in Hong Kong bilingual children (N = 481, age = 6–12 years old). Their nonverbal IQ, cognitive-linguistic skills, receptive and expressive vocabulary knowledge breadth, and vocabulary knowledge depth in Chinese and English were measured. Results demonstrated that morphological awareness was uniquely correlated with different aspects of vocabulary knowledge across Chinese and English. Phonological processing skills played different roles in vocabulary knowledge in L1 and L2. In addition, receptive vocabulary breadth uniquely contributed to expressive vocabulary breadth across languages. Moreover, both receptive and expressive vocabulary breadth contributed to vocabulary knowledge depth in L1 Chinese and L2 English. The findings highlight some shared and unique aspects of different vocabulary constructs across languages.
Assessment of Orthodontic Treatment Need and Oral Health-Related Quality of Life in Asthmatic Children Aged 11 to 14 Years Old: A Cross-Sectional Study

This study investigated the need for orthodontic treatment in asthmatic children aged 11 to 14 years and how the treatment affected their oral health-related quality of life (OHRQoL). Materials and Methods: This cross-sectional study was conducted at the dental clinic of the University of Salamanca in 2020–2022. The study selected a consecutive sample of 140 children with asthma (52.1% girls; 47.9% boys). This study used the Orthodontic Treatment Needs Index (OTN) to analyze the need for orthodontic treatment and the Children’s Perception Questionnaire (CPQ11–14) to assess OHRQoL. Results: Sex and age did not significantly influence the need for orthodontic treatment, although age may be considered influential for OHRQoL concerning oral symptoms (p < 0.01), functional limitations (p < 0.05), and total score on the CPQ11–14 questionnaire (p < 0.05): the younger the age, the greater the effect of the need for orthodontic treatment on OHRQoL. The social well-being of the patients was much more significantly impacted by the need for orthodontic treatment (15.7 ± 1.91) than by oral symptoms (7.64 ± 1.39), which were the least impacted. In all parts of the CPQ11–14 questionnaire and in the patients’ total scores, we observed significant agreement (p < 0.01) that treatment influenced OHRQoL. Conclusion: An inverse relationship exists between the severity of the treatment needed and OHRQoL.
Acoustically driven charge separation in semiconductor heterostructures sensed by optical spectroscopy techniques

We demonstrate a method of using a two-layer sandwich structure, which includes a LiNbO3 plate and a semiconductor heterostructure to create an inhomogeneous stress and piezoelectric harmonic potential in the semiconductor. Both the GaAs/AlGaAs quantum well (QW) structures and SiGe/Si heterostructures are attempted, working with and without using a piezoelectric field in the semiconductor layer. The standing-wave fields generated in the semiconductor and the electron and hole distributions driven by the piezoelectric field are computed by finite element method (FEM) techniques. It is experimentally shown that, in a GaAs/AlxGa1-xAs asymmetric double quantum well structure, the resonance enhancement of the narrower QW photoluminescence band is observed, which may be explained by the resonant charge transfer between the wider and narrower QWs. It is also shown that the piezoelectric fields quench the pure LO-phonon lines in the Raman spectra, whereas the coupled LO-phonon-plasmon mode strengthens. Experimental results indicate that the charge separation occurs in the plane of the QWs due to the piezoelectric fields. The recombination of carriers in the SiGe/Si heterostructures can be effectively enhanced by the presence of ultrasonic stress, displaying features consistent with varying electrical activity at dislocations.

SUMMARY A three parameter model is developed by reparameterizing and extending the distribution of the logarithm of a generalized gamma variate. The extreme value distributions for maxima and minima are included while the normal distribution is central. Asymptotic maximum likelihood theory is given and maximum likelihood distributions are studied, via simulation, in some special cases. A regression generalization is given.
Predictability Associated with Nonlinear Regimes in an Atmospheric Model

AbstractAtmospheric regimes are midlatitude flow patterns that persist for periods of time exceeding a few days. Here, the authors analyzed the output of an idealized atmospheric model (QG3) to examine the relationship between regimes and predictability.The regimes were defined as the regions of the QG3 phase subspace characterized by excess persistence probability relative to a benchmark linear empirical model (EMR) for geographically two-dimensional and then zonally averaged flow patterns. The regimes identified correspond to the opposite phases of the Arctic Oscillation (AO+ and AO−) and to a more regional pattern reflecting the positive phase of the North Atlantic Oscillation (NAO+). For all of these phase-space regime regions, the leading modes of the QG3 state vector decay to climatology at a slower rate than predicted by the EMR, which contributes to the maintenance of non-Gaussian regime anomalies. Predictable regimes are connected to “regime precursor” regions of the phase space, from which trajec.
A Comparison of Approaches for the Analysis of Interaction Effects Between Latent Variables Using Partial Least Squares Path Modeling

In social and business sciences, the importance of the analysis of interaction effects between manifest as well as latent variables steadily increases. Researchers using partial least squares (PLS) to analyze interaction effects between latent variables need an overview of the available approaches as well as their suitability. This article presents 4 PLS-based approaches: a product indicator approach (Chin, Marcolin, & Newsted, 2003), a 2-stage approach (Chin et al., 2003; Henseler & Fassott, in press), a hybrid approach (Wold, 1982), and an orthogonalizing approach (Little, Bovaird, & Widaman, 2006), and contrasts them using data related to a technology acceptance model. By means of a more extensive Monte Carlo experiment, the different approaches are compared in terms of their point estimate accuracy, their statistical power, and their prediction accuracy. Based on the results of the experiment, the use of the orthogonalizing approach is recommendable under most circumstances. Only if the orthogonalizing approach does not find a significant interaction effect, the 2-stage approach should be additionally used for significance test, because it has a higher statistical power. For prediction accuracy, the orthogonalizing and the product indicator approach provide a significantly and substantially more accurate prediction than the other two approaches. Among these two, the orthogonalizing approach should be used in case of small sample size and few indicators per construct. If the sample size or the number of indicators per construct is medium to large, the product indicator approach should be used.
