The Nonlocal Dual Phase Lag Model of a Thermoelastic Nanobeam Subjected to a Sinusoidal Pulse Heating

This paper investigates the vibration phenomenon of a nanobeam subjected to a sinusoidal pulse varying heat. A unified generalized nonlocal thermoelasticity model with dual phase lag (DPL) is deduced to solve this problem. The nonlocal theories of coupled thermoelasticity, generalized thermoelasticity with one relaxation time, and without energy dissipation can be extracted as limited and special cases of the present model. An analytical technique based on Laplace transform is used to calculate the vibration of deflection and the temperature. The inverse of Laplace transforms is computed numerically using Fourier expansion techniques. The effects of the nonlocal parameter, the phase lags, and the pulse width of the sinusoidal pulse are studied on the lateral vibration, the temperature, and the displacement of the nanobeam. Comparisons among the effects of the phase lags and the pulse width are discussed.
40% efficient metamorphic GaInP∕GaInAs∕Ge multijunction solar cells

An efficiency of 40.7% was measured and independently confirmed for a metamorphic three-junction GaInP∕GaInAs∕Ge cell under the standard spectrum for terrestrial concentrator solar cells at 240 suns (24.0W∕cm2, AM1.5D, low aerosol optical depth, 25°C). This is the initial demonstration of a solar cell with over 40% efficiency, and is the highest solar conversion efficiency yet achieved for any type of photovoltaic device. Lattice-matched concentrator cells have now reached 40.1% efficiency. Electron-hole recombination mechanisms are analyzed in metamorphic GaxIn1−xAs and GaxIn1−xP materials, and fundamental power losses are quantified to identify paths to still higher efficiencies.
Al[18F]F-NOTA-Octreotide Is Comparable to [68Ga]Ga-DOTA-TATE for PET/CT Imaging of Neuroendocrine Tumours in the Latin-American Population

Simple Summary In the present work we investigated the clinical utility of Al[18F]F-NOTA-Octreotide (Al[18F]F-OC) in comparison to [68Ga]Ga-DOTA-TATE in patients diagnosed with neuroendocrine tumours. Our aim was to verify the recently published, promising results for Al[18F]F-NOTA-Octreotide in the Latin-American population. Al[18F]F-NOTA-Octreotide provided excellent image quality, detected NET lesions with high sensitivity and represents a highly promising, clinical alternative to [68Ga]Ga-DOTA-TATE. Abstract PET imaging of neuroendocrine tumours (NET) is well established for staging and therapy follow-up. The short half-life, increasing costs, and regulatory issues significantly limit the availability of approved imaging agents, such as [68Ga]Ga-DOTA-TATE. Al[18F]F-NOTA-Octreotide provides a similar biodistribution and tumour uptake, can be produced on a large scale and may improve access to precision imaging. Here we prospectively compared the clinical utility of [68Ga]Ga-DOTA-TATE and Al[18F]F-NOTA-Octreotide in the Latin-American population. Our results showed that in patients with stage IV NETs [68Ga]Ga-DOTA-TATE presents higher physiological uptake than Al[18F]F-NOTA-Octreotide in the liver, hypophysis, salivary glands, adrenal glands (all p < 0.001), pancreatic uncinated process, kidneys, and small intestine (all p < 0.05). Nevertheless, despite the lower background uptake of Al[18F]F-NOTA-Octreotide, comparative analysis of tumour-to-liver (TLR) and tumour-to-spleen (TSR) showed no statistically significant difference for lesions in the liver, bone, lymph nodes, and other tissues. Only three discordant lesions in highly-metastases livers were detected by [68Ga]Ga-DOTA-TATE but not by Al[18F]F-NOTA-Octreotide and only one discordant lesion was detected by Al[18F]F-NOTA-Octreotide but not by [68Ga]Ga-DOTA-TATE. Non-inferiority analysis showed that Al[18F]F-NOTA-Octreotide is comparable to [68Ga]Ga-DOTA-TATE. Hence, our results demonstrate that Al[18F]F-NOTA-Octreotide provided excellent image quality, visualized NET lesions with high sensitivity and represents a highly promising, clinical alternative to [68Ga]Ga-DOTA-TATE.
Delivery of Catechins from Green Tea Waste in Single- and Double-Layer Liposomes via Their Incorporation into a Functional Green Kiwifruit Juice

Globally, about one million tonnes of tea products, which contain high concentrations of catechins and their derivatives, are wasted annually. Therefore, green tea waste catechins (GTWCs) are worth extracting, processing, protection, and delivery to the human body. In this study, GTWCs were extracted using a green method and then encapsulated in both single- (SLLs) and double-layer liposomes (DLLs). The encapsulated extracts were subsequently incorporated into a fresh green kiwifruit juice. SLLs and DLLs containing GTWCs had a size of about 180 and 430 nm with a zeta potential of −35 and +25 mV, respectively. Electron microscopy illustrated the separation of the SLLs and fibre in kiwifruit juice and attraction of the DLLs to this fibre. Liposomal GTWCs were effectively maintained in the kiwifruit juice during the 28 days of storage (4 °C), demonstrating the effectiveness of this delivery system for high-value bioactives (i.e., catechins) from such a by-product (i.e., green tea waste).
Inventory Management and Pharmaceutical Supply Chain Performance of Hospital Pharmacies in Bahrain: A Structural Equation Modeling Approach

The ultimate goal of healthcare systems is to offer care and the right treatment to patients. To achieve it, Pharmaceutical Supply Chain (PSC) in the healthcare system needs to be effective and efficient. This study aims to investigate the role of inventory level control and demand forecasting on PSC performance of hospital pharmacies. Data was collected from 171 respondents working in private hospitals in Bahrain using a survey questionnaire and was analyzed using a structural equation modeling approach. The study found a significant positive relationship between inventory level Control and PSC performance. Similarly, the relationship between demand forecasting and PSC performance was positive and significant. This research has implications for practice, including assisting hospital pharmacies to find the best practices to manage the pharmaceutical inventory and understanding the impact of inventory control and demand forecasting in PSC performance to ensure zero stockouts and withstand fluctuations in demand and supply. The results of the study can prove to be beneficial to hospitals and healthcare providers in establishing an appropriate PSC system and making better decisions in medicine supply.
The accumulation of damage in a glass-reinforced plastic under tensile and fatigue loading

Glass chopped strand mat/polyester resin specimens were subjected to tensile or fatigue loading. From examination of polished specimen edges fibre debonding and resin crack damage were quantified. The damage depended on the topography of the site observed, but by expressing damage as a fraction of that present at failure all the results could be reduced to single, nonlinear curves for debonding and cracking. Resin cracking damage and the loss of residual tensile strength of damaged specimens gave curves of similar quadratic form. It was concluded that the development of resin cracking was primarily responsible for the progressive loss of strength in a fatigue specimen. Damage depended on cycle ratio but not on fatigue stress. It was suggested that a suitable cumulative fatigue damage law would be nonlinear and stress-independent.
Strong consistency of maximum quasi-likelihood estimators in generalized linear models with fixed and adaptive designs

Strong consistency for maximum quasi-likelihood estimators of regression parameters in generalized linear regression models is studied. Results parallel to the elegant work of Lai, Robbins and Wei and Lai and Wei on least squares estimation under both fixed and adaptive designs are obtained. Let y 1 ,…, y n and x 1 ,…, x n be the observed responses and their corresponding design points (p x 1 vectors), respectively. For fixed designs, it is shown that if the minimum eigenvalue of Σx i x' i goes to infinity, then the maximum quasi-likelihood estimator for the regression parameter vector is strongly consistent. For adaptive designs, it is shown that a sufficient condition for strong consistency to hold is that the ratio of the minimum eigenvalue of Σx i x' i to the logarithm of the maximum eigenvalues goes to infinity. Use of the results for the adaptive design case in quantal response experiments is also discussed.
Constituents of Pulicaria inuloides and Cytotoxic Activities of Two Methoxylated Flavonols

Plants of the genus Pulicaria are known for providing traditional medicines, spices, herbal teas, and insect deterrents. Pulicaria inuloides (Poir.). DC. is one of the less chemically studied species within the genus. Hydroalcoholic extracts from roots and aerial parts of P. inuloides were analyzed using the UHPLC-PAD-MSn technique and revealed the presence of six caffeoylquinic and eleven caffeoylhexaric conjugates together with hydroxykaempferol dimethyl ether and quercetagetin trimethyl ether. Moreover, constituents of chloroform extract from the whole P. inuloides plants were isolated and identified by spectroscopic methods. One new and four known caryophyllene derivatives, three thymol derivatives, and four polymethoxylated flavonols were found in the analyzed extract. The structure of the new compound was established by spectroscopic methods (HRESIMS, 1H NMR, 13C NMR, COSY, HSQC, HMBC, NOESY). The cytotoxicity of 6-Hydroxykaempferol 3,7-dimethyl ether and quercetagetin 3,7,3’-trimethyl ether (chrysosplenol C), which are major flavonols isolated from the plant, were tested on prostate epithelial cells (PNT2), prostate cancer cells (DU145 and PC3), human keratinocytes (HaCaT), and melanoma cells (HTB140 and A375). Both flavonols demonstrated moderate cytotoxic activity against PC3 cells (IC50 = 59.5 µM and 46.6 µM, respectively). The remaining cell lines were less affected (IC50 > 150 µM).
Multispectral scanning laser ophthalmoscopy combined with optical coherence tomography for simultaneous in vivo mouse retinal imaging

A compact, non-invasive multi-modal system has been developed for in vivo mouse retina imaging. It is configured for simultaneously detecting green and red fluorescent protein signals with scanning laser ophthalmoscopy (SLO) back-scattered light from the SLO illumination beam, and depth information about different retinal layers by means of Optical Coherence Tomography (OCT). Simultaneous assessment of retinal characteristics with different modalities can provide a wealth of information about the structural and functional changes in the retinal neural tissue and chorio-retinal vasculature in vivo. Additionally, simultaneous acquisition of multiple channels facilitates analysis of the data of different modalities by automatic temporal and structural co-registration. As an example of the instrument’s performance we imaged the retina of a mouse with constitutive expression of GFP in microglia cells (Cx3cr1GFP/+), and which also expressed the red fluorescent protein mCherry in Müller glial cells by means of adeno-associated virus delivery (AAV2) of an mCherry cDNA driven by the GFAP (glial fibrillary acid protein) promoter.
The magnetohydrodynamics of umbral flux tubes. I: Theoretical model

Toward the goal of understanding the nature of umbral fine structure-specifically, umbral dots-from a theoretical perspective,,we investigate the magnetohydrodynamic consequences of thin, vertical gas columns embedded in sunspot umbrae. In the theoretical construct presented in this paper, both these gas columns and the surrounding umbral stratification are permeated by a magnetic field, the field strength of the column (umbral flux tube) being weaker than that of the ambient medium. We solve the steady-state magnetohydrodynamic equations numerically in the thin flux tube approximation, thus allowing for stationary internal mass flows and the lateral exchange of radiative energy
Statistics of Langmuir wave amplitudes observed inside Saturn's foreshock by the Cassini spacecraft

We present the first systematic study of Langmuir wave amplitudes in Saturn's foreshock using the Cassini Radio and Plasma Wave Science/Wideband Receiver measurements. We analyzed all foreshock crossings from June 2004 to December 2009 using an automatic method to identify Langmuir waves. Using this method, almost 3 × 105 waveform intervals of typical duration of about a minute were selected. For each selected waveform interval the position of the satellite inside the foreshock was calculated using an adaptive bow shock model, which was parametrized by the observed magnetic field and plasma data. We determined the wave amplitudes for all waveform intervals, and we found that the probability density function amplitudes follow a lognormal distribution with a power law tail. A nonlinear fit for this tail gives a power law exponent of −1.37 ± 0.01. The distribution of amplitudes as a function of the depth in the foreshock shows the onset of the waves near the upstream boundary with its maximum slightly shifted inside the foreshock (∼1 RS). The amplitudes then fall off with increasing depth in the downstream region. Our results are in agreement with previous observations and roughly follow the generally accepted stochastic growth theory mechanism for the foreshock region, with an exception at the highest observed amplitudes. The estimated energy density ratio W for largest amplitudes does not exceed 10−2, suggesting that modulational instability is not relevant for a large majority of waves. The decay instability can be important for the stronger electrostatic waves in Saturn's foreshock, as was previously reported for multiple solar system planets.

Personality (16PF) Correlates of WAIS Scales: A Replication

In their investigation of Cattell’s (1971) hypothesized &dquo;ability factor stimulators,&dquo; Turner, Willerman, and Horn (1976) correlated the four major second-order factors of the Sixteen Personality Factor Questionnaire (16PF) with the Wechsler Adult Intelligence Scale (WAIS) subscale and IQ scores for adults of above-average intelligence. Independence (QIV) was substantially related to WAIS scores for both males and females, while Cortertia (QIII) was correlated for males only. The purpose of the present study was to examine these WAIS-16PF relationships for a clinical population.
Goal-Oriented Wireless Communication for a Remotely Controlled Autonomous Guided Vehicle

This letter considers a remote control Autonomous Guided Vehicle (AGV), where packets carrying sensory data and control information are sent through a time-correlated wireless fading channel. We illustrate there is an inherent dependency between the data rate and the resulting control accuracy for such a system. We propose a goal-oriented wireless solution, in which data transmission rate is continuously adapted according to Age-of-Loop metric to achieve precise remote trajectory control of an AGV. The numerical analysis shows that the proposed solution provides higher control accuracy at the AGV trajectory compared to straightforward fixed-rate transmission policies, and to a reference solution based on Age-of-Information metric, more commonly used in research of wireless networked control systems.
Nonlinear theory of the interaction of sound waves with an inhomogeneous magnetized plasma in the resonant slow wave layer

The nonlinear theory of driven magnetohydrodynamic (MHD) waves in the resonant slow wave dissipative layer developed by Ruderman, Hollweg, and Goossens [Phys. Plasmas 4, 75 (1997)] is used to study the interaction of sound waves with a static one-dimensional planar magnetic plasma configuration. This configuration is a nonhomogeneous magnetic slab (region II) sandwiched by a homogeneous magnetic field free plasma (regions I) and a homogeneous magnetic plasma (region III). The equilibrium magnetic field is unidirectional. An incoming sound wave is launched from region I, and the equilibrium quantities and the parameters of the incoming sound wave are chosen in such a way that the wave is evanescent in region III and resonates with a slow local MHD wave in region II. The analysis is restricted to incoming sound waves with wave vectors in the plane determined by the equilibrium magnetic field and the direction of inhomogeneity, so that there is no resonance with a local Alfven wave. Partial reflection of the incoming sound wave from region II generates an outgoing sound wave in region I. The nonlinearity parameter introduced by Ruderman et al. is assumed to be small, and a regular perturbation analysis is used to determine the wave solution. The present analysis shows that nonlinearity in the resonant slow wave dissipative layer causes the following new effects in comparison with results obtained on the basis of linear theory: (i) higher harmonic contributions are generated in the wave solution in the dissipative layer and also in the outgoing sound wave in addition to the fundamental harmonic. Outside the dissipative layer the amplitude of each harmonic contribution is of a higher order with respect to the small nonlinearity parameter than inside the dissipative layer. This property reflects the fact that nonlinearity is only taken into account in the dissipative layer, so that the higher harmonic contributions to the outgoing wave are only due to the interaction of the external plasma motions with the plasma motions in the dissipative layer; (ii) the coefficient of wave energy absorption and the absolute value of the jump in the normal velocity are decreased.
Ordered Linear Smoothers

This paper deals with the following approach for estimating the mean mu of an n-dimensional random vector Y: first, a family S of n x n matrices is specified. Then, an element S is an element of S is selected by Mallows C-L, and mu = S.Y. The case is considered that S is an ''ordered linear smoother'' according to some easily interpretable, qualitative conditions. Examples include linear smoothing procedures in nonparametric regression (as, e.g., smoothing splines, minimax spline smoothers and kernel estimators). Stochastic probability bounds are given for the difference (1/n)parallel to mu - S.Y parallel to(2)(2) - (1/n)parallel to mu - S mu.Y parallel to(2)(2) where S mu denotes the minimizer of (1/n)parallel to mu - S.Y parallel to(2)(2) for S is an element of S. These probability bounds are generalized to the situation that S is the union of a moderate number of ordered linear smoothers. The results complement work by Li on the asymptotic optimality of C-L. Implications for nonparametric regression are studied in detail. It is shown that there exists a direct connection between James-Stein estimation and the use of smoothing procedures, leading to a decision-theoretic justification of the latter. Further conclusions concern the choice of the order of a smoothing spline or a minimax spline smoother and the rates of convergence of smoothing parameters.
Effects of rear spoilers on ground vehicle aerodynamic drag

Purpose – The purpose of this paper is to examine the aerodynamic effects of rear spoiler geometry on a sports car. Today, due to economical, safety and even environmental concerns, vehicle aerodynamics play a much more significant role in design considerations and rear spoilers play a major role in this area. Design/methodology/approach – A 2-D vehicle geometry of a race car is created and solved using the computational fluid dynamics (CFD) solver FLUENT version 6.3. The aerodynamic effects are analyzed under various vehicle speeds with and without a rear spoiler. The main results are compared to a wind tunnel experiment conducted with 1/18 replica of a Nascar. Findings – By the CFD analysis, the drag coefficient without the spoiler is calculated to be 0.31. When the spoiler is added to the geometry, the drag coefficient increases to 0.36. The computational results with the spoiler are compared with the experimental data, and a good agreement is obtained within a 5.8 percent error band. The uncertainty a.
Structure and Mechanical Properties of a Porous Polymer Material via Molecular Dynamics Simulations

We characterize, using molecular dynamics simulations, the structure and mechanical response of a porous glassy system, obtained via arrested phase separation of a model polymer melt. In the absence of external driving, coarsening dynamics, with power-law time dependence, controls the slow structural evolution, in agreement with what was reported for other phase-separating systems. The mechanical response was investigated in athermal quasi-static conditions. In the elastic regime, low values for the Young’s and shear modulus were found, as compared to dense glassy systems, which originate from the porous structure. For large deformations, stress–strain curves show a highly intermittent behavior, with avalanches of plastic events. The stress-drop distribution is characterized exploring a large set of parameters. This work goes beyond the previous numerical studies on atomic porous materials, as it first examines the role of chain connectivity in the elastic and plastic responses of materials of this type.
Wing Deformation of an Airborne Wind Energy System in Crosswind Flight Using High-Fidelity Fluid–Structure Interaction

Airborne wind energy (AWE) is an emerging technology for the conversion of wind energy into electricity. There are many types of AWE systems, and one of them flies crosswind patterns with a tethered aircraft connected to a generator. The objective is to gain a proper understanding of the unsteady interaction of air and this flexible and dynamic system during operation, which is key to developing viable, large AWE systems. In this work, the effect of wing deformation on an AWE system performing a crosswind flight maneuver was assessed using high-fidelity time-varying fluid–structure interaction simulations. This was performed using a partitioned and explicit approach. A computational structural mechanics (CSM) model of the wing structure was coupled with a computational fluid dynamics (CFD) model of the wing aerodynamics. The Chimera/overset technique combined with an arbitrary Lagrangian–Eulerian (ALE) formulation for mesh deformation has been proven to be a robust approach to simulating the motion and deformation of an airborne wind energy system in CFD simulations. The main finding is that wing deformation in crosswind flights increases the symmetry of the spanwise loading. This property could be used in future designs to increase the efficiency of airborne wind energy systems.
