A DETAILED COMPARISON OF NON-PARALLEL STABILITY RESULTS WITH EXPERIMENTAL DATA

The objective of the work described in this article is to conduct a detailed comparison of non-parallel stability results with experimental measurements. To this end, a stability analyser based on the linear, three-dimensional, incompressibl e Parabolised Stability Equations (PSE) was developed. The PSE formulation takes into account the variations, of the mean flow and disturbance quantities in the principal direction of the flow (typically the chordwise direction), resulting in a space-marching procedure subject to a normalisation relation. In the PSE approach, the amplitude of a perturbation can be related to a "physically measurable" quantity, a possibility that does not exist with the parallel stability theory. It is therefore expected that the PSE results may provide a better reproduction of some experimentally-observed features, such as doublepeaked spectra, than has so far been obtained using the parallel theory. In this article, fluctuation spectra obtained by the PSE approach on the ONERA AFVD 82 swept wing are compared to hot film experimental data. The predictions are shown to be
Network Pharmacology Combined with an Experimental Validation Study to Reveal the Effect and Mechanism of Eucommia ulmoides Leaf Polysaccharide against Immunomodulation

In the present study, the immuno-enhancing effect of Eucommia ulmoides leaf polysaccharide (ELP) was investigated in immunosuppressed mice induced by cyclophosphamide (CTX). To evaluate the immune enhancement mechanism of ELP, the immunoregulation effect of ELP was evaluated in vitro and in vivo. ELP is primarily composed of arabinose (26.61%), galacturonic acid (25.1%), galactose (19.35%), rhamnose (16.13%), and a small amount of glucose (12.9%). At 1000~5000 μg·mL−1, ELP could significantly enhance the proliferation and the phagocytosis of macrophages in vitro. Additionally, ELP could protect immune organs, reduce pathological damage, and reverse the decrease in the hematological indices. Moreover, ELP significantly increased the phagocytic index, enhanced the ear swelling response, augmented the production of inflammatory cytokines, and markedly up-regulated the expression of IL-1β, IL-6, and TNF-α mRNA levels. Furthermore, ELP improved phosphorylated p38, ERK1/2, and JNK levels, suggesting that MAPKs might be involved in immunomodulatory effects. The results provide a theoretical foundation for exploring the immune modulation function of ELP as a functional food.
Proximal Minimization Methods with Generalized Bregman Functions

We consider methods for minimizing a convex function f that generate a sequence {xk} by taking xk+1 to be an approximate minimizer of f(x)+Dh(x,xk)/ck, where ck > 0 and Dh is the D-function of a Bregman function h. Extensions are made to B-functions that generalize Bregman functions and cover more applications. Convergence is established under criteria amenable to implementation. Applications are made to nonquadratic multiplier methods for nonlinear programs.
Religious Bodies–Lutheran Chaplains Interpreting and Asserting Religiousness of People with Severe Dementia in Finnish Nursing Homes

The prevalence of dementia is increasing globally as populations grow older. Moderate and severe dementia are the main reasons for older people entering long-term care in Finland, and the vast majority of nursing home residents have it. Regarding mild dementia, religiousness is known to slow the progress of the disease, offer solace, and maintain a life-long identity. However, we know practically nothing about the religiousness of people with severe dementia. This study sought to fill the gap by interviewing Lutheran chaplains working in Finnish nursing homes. The data were subjected to qualitative content analysis to understand: (I) how people with severe dementia may express their remaining religiousness and (II) how the chaplains asserted the religiousness of people whom their words often did not reach. The clearest expressions of religiousness found were bodily, including expressions of emotions and fumbling liturgical movements. The chaplains utilized prayer services, active presence, and generational intelligence to respond to residents’ religiousness. The main conclusion is that people with severe dementia can express their faith and are eager to practice it when opportunities are provided to do so. Our research challenges care providers and religious communities to better acknowledge the religiousness of people with severe dementia.
Childcare practices among Colombian primary caregivers of under-five children: A comparison across socio-demographic characteristics

Approximately 200 million children worldwide risk not fulfilling their full developmental potential, and most of them come from areas characterized by systematic inequality and scarcity of resources. Because under-five children of families that experience economic deprivation report poorer developmental outcomes, lately greater attention has been directed at studying and intervening in caregiver practices during early childhood. This study aimed to describe childcare practices utilized by caregivers of under-five children (N = 110) residing in a Colombian city; it also sought to test differences in caregiving practices across sociodemographic characteristics. Results from nonparametric statistical analyses showed that caregivers of high- and medium-income families engaged more frequently in tasks related to sleep hygiene (ꭓ2(2) = 9.34, p = . 009, and less negative socio-emotional interactions (e.g., punishment) than low-income peers (ꭓ2(2) = 9.33, p = . 009). Caregivers who were employed or students reported more involvement in sleep hygiene tasks and less negative emotional interactions than homemakers and retired caregivers (w = 1878, p <.001). An increase in the number of children in the household was positively associated with greater negative socioemotional care, r = . 21, S = 173556, p = . 02. Interventions and public policy would benefit from targeting full-time primary caregivers of low-income children aged 0-5. Particularly, by complementing their competencies to foster socio-emotional development.
Small-Scale Properties of Turbulent Rayleigh-Bénard Convection

The properties of the structure functions and other small-scale quantities in turbulent Rayleigh-Benard convection are reviewed, from an experimental, theoretical, and numerical point of view. In particular, we address the question of whether, and if so where in the flow, the so-called Bolgiano-Obukhov scaling exists, i.e., Sθ(r) ∼ r2/5 for the second-order temperature structure function and Su(r) ∼ r6/5 for the second-order velocity structure function. Apart from the anisotropy and inhomogeneity of the flow, insufficiently high Rayleigh numbers, and intermittency corrections (which all hinder the identification of such a potential regime), there are also reasons, as a matter of principle, why such a scaling regime may be limited to at most a decade, namely the lack of clear scale separation between the Bolgiano length scale LB and the height of the cell.
Radiation of plasma waves by a conducting body moving through a magnetized plasma

There are many situations of interest in space and astrophysics which consist of a conducting body moving through a magnetized plasma. It is well known that large conducting objects which move slowly across magnetic field lines radiate low frequency (Alfven) waves. In this paper we study the interaction between a plasma and a moving conductor in order to estimate the total power radiated at all frequencies. Toward this end, we develop a formalism which permits us to compute the response of the plasma to an external current source. We then derive an integral equation which relates the source current to the electrical properties of the conducting body. Since the integral equation is prohibitively difficult to solve, we estimate the total radiated power for simple geometries using energy conservation and a source current deduced by physical reasoning. We find in general that radiation is produced at all frequencies for which one of the plasma modes has zero phase velocity in some direction. The mechanism by which this radiation is produced is analogous to Cherenkov radiation. In the cold plasma approximation, in a plasma for which ωp² ≫ Ωe² and V² ≪ cA² ≪ c², there is radiation in three frequency bands: ω < Ωi, ωLH < ω < Ωe, and ωp < ω < ωUH, where V is the speed of the body, cA is the Alfven speed, c is the speed of light in vacuum, ω is the frequency of the radiation, and Ωi, ωLH, Ωe, ωp, ωUH are the ion cyclotron, lower hybrid, electron cyclotron, plasma, and upper hybrid frequencies, respectively. To gain a better understanding of the properties of the plasma waves in these frequency bands, we present polar plots of the phase and group velocities of these waves. Finally, we present estimates of radiated power for a sphere and for a cylinder of arbitrary size. We find that a wire 10 km long and 1 mm in radius radiates about 40 watts. The Jovian satellite Io, known to be a strong source of waves in the first frequency band, also radiates 2.9×10−7 times as much power in the second frequency band.
Dental Fear and Anxiety of Chinese Preschool Children in a School-Based Outreach Service Using Silver Diamine Fluoride for Caries Control: A Cross-Sectional Study

Limited data are available regarding the patient-based outcomes of SDF therapy in the kindergarten setting. This study aims to evaluate the dental fear and anxiety (DFA) of preschool children after participating in a school-based outreach service using SDF to arrest early childhood caries (ECC). The study recruited 3- to 5-year-old children with untreated ECC. A trained dentist performed a dental examination and applied SDF therapy to the carious lesions. ECC experience was measured using the dmft index. Questionnaires for parents were used to collect the children’s demographic information and their dental treatment experiences. The children’s DFA before and immediately after SDF therapy was assessed using the self-reported Facial Image Scale (FIS) on a Likert scale of 1 (very happy) to 5 (very distressed). The association between the children’s DFA after SDF therapy and the potentially related factors, including demographic background, caries experience, and DFA before SDF therapy, were analysed using bivariate analysis. Three hundred and forty children (187 boys, 55%) joined this study. Their mean (SD) age and dmft scores were 4.8 (0.9) and 4.6 (3.6), respectively. Most of them (269/340, 79%) never had a dental visit. After SDF therapy, 86% (294/340) of the children exhibited no or low DFA (FIS ≤ 3), whereas 14% (46/340) reported high DFA (FIS > 3). No factor was associated with children’s DFA after SDF therapy (p > 0.05). This study showed most preschool children with ECC exhibited no or low DFA after SDF therapy in a school setting.
A Detailed Normal-Mode Energetics of the General Circulation of the Atmosphere

AbstractAn energetics formulation is here introduced that enables an explicit evaluation for the conversion rates between available potential energy and kinetic energy, the nonlinear interactions of both energy forms, and their generation and dissipation rates, in both the zonal wavenumber and vertical mode domains. The conversion rates between available potential energy and kinetic energy are further decomposed into the contributions by the rotational (Rossby) and divergent (gravity) components of the circulation field. The computed energy terms allow one to formulate a detailed energy cycle describing the flow of energy among the zonal mean and eddy components, and also among the barotropic and baroclinic components. This new energetics formulation is a development of the 3D normal-mode energetics scheme. The new formulation is applied on an assessment of the energetics of winter (December–February) circulation in the 40-yr ECMWF Re-Analysis (ERA-40), the 25-yr Japan Meteorological Agency Reanalysis (JR.
Exploring Relationship of Job Satisfaction, Organizatonal Culture, and Employee Performance in Small Medium Enterprise

Purpose: The objective of this study was to re-examined the relationship of job satisfaction, organizational culture and employee performance. Theoretical framework: There were several studies that examine the relationship between organizational culture, job satisfaction, and employee performance. The employee performance is a consequence of organizational culture and employee job satisfaction. The relationship between the three variables is not surprising, especially the relationship between the two types of performance measures, in-role performance (IRP) and extra-role performance (ERP). Design/methodology/approach: This study aims to re-examine the relationship and influence job satisfaction (JS), organizational culture (OC), in-role performance (IRP), and extra-role performance (ERP) using 376 employees who work in several micro, small and medium scale manufacturing companies in Yogyakarta, Indonesia. The factor analysis was used to test the validity, and Cronbach’ Alpha for reliability of the instrument. The structural equation modeling was used to test the relationship model. Findings: The results of this study revealed that JS is a variable that is not related to the other three variables and does not influence either IRP or ERP. This study found that JS is related to and influenced by the organizational culture (OC) adopted. This study strengthened the findings of previous studies that OC is one of the important factors to improve employee performance. Research, Practical & Social implications: Small Medium Enterprises must strengthen organizational culture in order to increase job satisfaction and employee performance, both IRP and ERP. The use of longitudinal data needs to be used to test the mediation of the model. Other raters also need to be used to assess employee performance and eliminate common method variances. Originality/value: Job satisfaction is not always an independent variable as in many studies but can be a consequence of individual internal and external factors.
Phylogenetic and morphological analyses of Japanese Aquarius water strider, with a new synonym

The genus Aquarius, of the subfamily Gerrinae, was formerly divided into two species and one subspecies in Japan (A. paludum paludum, A. paludum amamiensis and A. elongatus, respectively). Aquarius haliplous Yasunaga et al. 2018 has recently been described as a new species, which occurs in brackish waters of Nagasaki Prefecture and is found sympatrically with the widely distributed species, A. p. paludum. However, they are considered to be speciated, with no cross‐breeding. In this study, molecular phylogenetic and morphological analyses were undertaken using the mitochondrial DNA COI (529 bp) and nuclear DNA histone H3 (314 bp) gene regions to investigate the genetic and morphological differentiation in the genus Aquarius, including A. haliplous, throughout Japan (including the islands). The results show that, unlike A. p. paludum, A. p. amamiensis and A. haliplous, A. elongatus displays substantial genetic differentiation. Considering that, although morphological differences exist in the antennae of A. p. paludum and A. p. amamiensis, A. haliplous has no clear genetic or morphological difference from A. p. paludum, and hence cannot be classified as a distinct species. Therefore, we propose that A. haliplous be synonymized with A. paludum.
Effects of cement as a substitute binder on strength and durability of fly ash–rice husk ash geopolymer concrete

Utilization of industrial by‐products in concrete is an effective way to reduce the exhaustion of raw materials for concrete production, but it can lead to degradation in concrete properties. Therefore, research efforts are required to achieve a balance between waste utilization and concrete performance. This study examined the strength and durability performance of geopolymer concrete (GPC) developed from fly ash (FA) and fine rice husk ash (FRHA) as main binders (50/50), with partial OPC substitution at different levels (0%–30%). Various properties like workability, compressive strength, water absorption, chloride penetration resistance, carbonation depth, electrical resistivity (ER), and acid attack resistance were experimentally investigated. Results indicated that there was a noticeable improvement in the workability with 20% OPC substitution, achieving the highest slump of 110 mm. The highest compressive strength (50 MPa) was attained with 15% OPC substitution after 90 days. Mix FR85C15 (15% OPC replacement) showed the highest durability performance at all ages through various indicators, that is, water absorption, charge passed, carbonation depth, and ER. Scanning electron microscopy and energy dispersive spectroscopy analyses also validated the enhanced microstructure of FR85C15 compared with other mixes. When exposed to sulfuric acid (H2SO4), Mix FR85C15 showed a minimal loss of 14% in compressive strength. It was concluded that GPC produced using FA and FRHA substituting OPC (up to 15%) can potentially be utilized for structural applications.
On over-reflexion

Reflexion coefficients greater than unity have now been predicted for a variety of different systems involving waves propagating towards a shear layer, but almost invariably only in regions of parameter space for which the layer exhibits Kelvin-Helmholtz instability. This paper contains a study of two examples in which, for appropriate parameter values, there are no such instabilities to obscure (or even prevent) the ‘over-reflexion’ of an incident wave, namely (a) hydro-magnetic internal gravity waves meeting a vortex-current sheet in a stratified fluid and (b) magneto-acoustic waves meeting a vortex sheet in a compressible fluid. In the former case the energetic aspects of over-reflexion are examined in detail, thus displaying the way in which the excess reflected energy is extracted from the mean motion and the sense in which the transmitted wave may be viewed, by analogy with certain concepts employed in plasma physics, as a carrier of so-called ‘negative energy’.
Phase operators via group contraction

The problem of quantization of the classical phase of a harmonic oscillator (HO) is solved here in two steps. First, polar decomposition of the step operators of the u(2) algebra is performed. Second, the method of group contraction is used through which, in the limit j→∞, a,a° is passed to for the quantized HO and its Hermitian phase operators. Also, phase states, i.e., states with sharply defined phase, are constructed and the dynamical aspects of the contraction limit between the Jaynes–Cummings model (JCM) and a finite‐dimensional counterpart with increasing j parameter are studied. Finally, the old problem of the phase operators is discussed in the wider frame of rank‐1 algebras and classify the previous works in this frame.
Possibilities of finite calculus in computational mechanics

The expression ‘finite calculus’ refers to the derivation of the governing differential equations in mechanics by invoking balance of fluxes, forces, etc. in a space–time domain of finite size. The governing equations resulting from this approach are different from those of infinitesimal calculus theory and they incorporate new terms which depend on the dimensions of the balance domain. The new governing equations allow the derivation of naturally stabilized numerical schemes using any discretization procedure. The paper discusses the possibilities of the finite calculus method for the finite element solution of convection–diffusion problems with sharp gradients, incompressible fluid flow and incompressible solid mechanics problems and strain localization situations.

A multistate external cavity laser diode

A semiconductor laser diode in a photon cavity containing a mirror whose optical bandwidth is less than the classical cavity mode spacing can have multiple lasing states at the same bias current. The physics determining the behavior of this nonlinear multistate device is self-consistency between photon number, carrier number, and refractive index.

AMC-Loaded Low-Profile Broadband Printed 2×2 Array With Gain and Isolation Enhancement Using Equivalent Circuit Model for Wireless Systems

A <inline-formula> <tex-math notation="LaTeX">$2\times 2$ </tex-math></inline-formula> array of printed antenna loaded by planar Giuseppe Peano artificial magnetic conductor (AMC) is presented for vehicular wireless systems. The four-element of the proposed array by utilizing diverse polarized directions of the printed dipoles with a <inline-formula> <tex-math notation="LaTeX">$5\times 5$ </tex-math></inline-formula> AMC reflector achieves a wideband antenna with enhanced properties. It shows the measured S-parameters of the wide bandwidths from 3.30 to 6.02 GHz with increased stable gains and efficiencies (more than 90%) for all elements. Moreover, the appropriate isolation of greater than 30 dB between the elements is achieved. The proposed design of the printed dipoles includes T-shaped microstrip dipoles and a feedline system as a T-shape to broaden the bandwidth in 4.7-6.02 GHz (<inline-formula> <tex-math notation="LaTeX">$\text{S}_{11}\le $ </tex-math></inline-formula> -10 dB). By utilizing the <inline-formula> <tex-math notation="LaTeX">$3\times 3$ </tex-math></inline-formula> Giuseppe Peano AMC reflector into the one element of the printed dipole, enhanced radiation efficiency and −10 dB measured bandwidth from 3.26 to 6.02 GHz (60%) is achieved for vehicular wireless systems. The proposed design with AMC with respect to the antenna without AMC indicates a reduced size of 70%, increased gain up to 8.4 dBi, and uni-directional radiation patterns. The new AMC unit cell is configured by the Giuseppe Peano design to resonate at 5.36 GHz in 4.27-6.34 GHz (39%). Finally, the suggested equivalent transmission line model of the <inline-formula> <tex-math notation="LaTeX">$2\times 2$ </tex-math></inline-formula> array with AMC surface is introduced with a suitable agreement between the results of reflection coefficients.
