A Flexible Ultrasensitive IgG-Modified rGO-Based FET Biosensor Fabricated by Aerosol Jet Printing

High-performance biosensors are the key elements for rapid and real-time detection of specific biomolecules. Herein, an ultrasensitive FET biosensor on a flexible polymer substrate was reported, and the aerosol jet printing (AJP) method offers a unique way for low-cost mass manufacturing of the flexible sensors. The stable PBA functionalized rGO layer and the goat-anti-rabbit IgG layer on the rGO were both printed by AJP method between the source/drain electrodes. The flexibe biosensors exposure to low concentrations of target rabbit IgG showed dramatic increase in the source-drain current, which exhibited great sensing performance with the lowest detection limit of 13 fM.
Compressive HDR Light Field Imaging Using a Single Multi-ISO Sensor

In this paper, we propose a new design for single sensor compressive HDR light field cameras, combining multi-ISO photography with coded mask acquisition, placed in a compressive sensing framework. The proposed camera model is based on a main lens, a multi-ISO sensor and a coded mask located in the optical path between the main lens and the sensor that projects the coded spatio-angular information of the light field onto the 2D sensor. The model encompasses different acquisition scenarios with different ISO patterns and gains. Moreover, we assume that the sensor has a built-in color filter array (CFA), making our design more suitable for consumer-level cameras. We propose a reconstruction algorithm to jointly perform color demosaicing, light field angular information recovery, HDR reconstruction, and denoising from the multi-ISO measurements formed on the sensor. This is achieved by enabling the sparse representation of HDR light fields using an overcomplete HDR dictionary. We also provide two HDR light field data sets: one synthetic data set created using the Blender rendering software with two baselines, and a real light field data set created from the fusion of multi-exposure low dynamic range (LDR) images captured using a Lytro Illum light field camera. Experimental results show that, with a sampling rate as low as 2.67$\%$, using two shots, our proposed method yields a higher light field reconstruction quality compared to the fusion of multiple LDR light fields captured with different exposures, and with the fusion of multiple LDR light fields captured with different ISO settings.
Molecular Dynamics Simulation of Two-Phase Structures of Copper Formed by Laser Grooving

It is a concerned problem that what influences of cooling rate on evolution of microstructures of the treated and untreated Cu are during solidification process after Cu’s being melted by laser grooving. Based on the embedded-atom method, molecular dynamics simulations have been performed on the cooling processes of liquid metal Cu by using crystal-liquid configuration method at six different cooling rates. Through the two-phase structural features, pair correlation function, average atomic energy and mean square displacement analysis, it is found that the cooling rate plays a critical role on the solidification process to the liquid Cu. The liquid Cu becomes its crystalline state during relatively low cooling rate, while the glass transition of the liquid Cu is performed with the relatively high cooling rate. The solidification process of the liquid Cu has effect on the solid crystal Cu and leads to form the indented interface between two-phase structures.
Determinants of Consumers' Willingness to Participate in Fast Fashion Brands' Used Clothes Recycling Plans in an Omnichannel Retail Environment

Omnichannel retailing and sustainability are two important challenges for the fast fashion industry. However, the sustainable behavior of fast fashion consumers in an omnichannel environment has not received much attention from researchers. This paper aims to examine the factors that determine consumers’ willingness to participate in fast fashion brands’ used clothes recycling plans in an omnichannel retail environment. In particular, we examine the impact of individual consumer characteristics (environmental attitudes, consumer satisfaction), organizational arrangements constitutive for omnichannel retailing (channel integration), and their interplay (brand identification, impulsive consumption). A conceptual model was developed based on findings from previous research and tested on data that were collected online from Chinese fast fashion consumers. Findings suggest that consumers’ intentions for clothes recycling are mainly determined by individual factors, such as environmental attitudes and consumer satisfaction. Organizational arrangements (perceived channel integration) showed smaller effects. This study contributes to the literature on omnichannel (clothing) retail, as well as on sustainability in the clothing industry, by elucidating individual and organizational determinants of consumers’ recycling intentions for used clothes in an omnichannel environment. It helps retailers to organize used clothes recycling plans in an omnichannel environment and to motivate consumers to participate in them.
Memory dynamic output feedback controller based on asynchronous event‐triggered robust H‐infinity control for nonlinear ICPSs under data injection attacks

Aiming at reducing the influence caused by data injection attacks, an asynchronous event‐triggered robust H‐infinity control (AERHC) is proposed for the stability of nonlinear ICPSs suffering from data injection attacks. A robust H‐infinity memory dynamic feedback control technique is designed to guarantee asymptotic stability of the closed‐loop system under a Lyapunov functional and the robust H∞ stability criterion. Furthermore, a memory dynamic feedback controller which has five controller gains different from each other for mitigating the conservative of nonlinear ICPSs and for resisting data injection attacks in ICPSs. Meanwhile, an asynchronous event‐triggered strategy is adopted to reduce the data communication frequency among nonlinear ICPSs components, and it effectively handle the influence of coupling problem between the measurement channel and the control channel. Finally, simulation tests are conducted by using MATLAB to control the robustness of the motor angle position of electromechanical system by using AERHC, which verify that the correctness and effectiveness of the proposed method.
Experimentally verified inductance extraction and parameter study for superconductive integrated circuit wires crossing ground plane holes

As the complexity of rapid single flux quantum (RSFQ) circuits increases, both current and power consumption of the circuits become important design criteria. Various new concepts such as inductive biasing for energy efficient RSFQ circuits and inductively coupled RSFQ cells for current recycling have been proposed to overcome increasingly severe design problems. Both of these techniques use ground plane holes to increase the inductance or coupling factor of superconducting integrated circuit wires. New design tools are consequently required to handle the new topographies. One important issue in such circuit design is the accurate calculation of networks of inductances even in the presence of finite holes in the ground plane. We show how a fast network extraction method using InductEx, which is a pre- and post-processor for the magnetoquasistatic field solver FastHenry, is used to calculate the inductances of a set of SQUIDs (superconducting quantum interference devices) with ground plane holes of different sizes. The results are compared to measurements of physical structures fabricated with the IPHT Jena 1 kA cm−2 RSFQ niobium process to verify accuracy. We then do a parameter study and derive empirical equations for fast and useful estimation of the inductance of wires surrounded by ground plane holes. We also investigate practical circuits and show excellent accuracy.
Efficient Algorithm to Calculate a Time-Domain Echo Signal from Moving Targets Based on Physical Optics and the Application to an Autonomous Driving Simulation

An automotive radar simulator is proposed that can consider a dynamic driving scenario. The impulse response is computed based on the distance between the radar and the mesh position and the radar equation. The first-order physical optics technique is used to calculate the backscattering by the meshes, which can efficiently consider the shape of the target; however, because the radar operating frequency is very high, the required amount of mesh for discretization is large. Hence, the calculation of the time-domain echo signal requires considerable computational time. To reduce this numerical complexity, a new scheme is proposed to accurately approximate the time-domain baseband signal generated by the large number of meshes. The radar adopts the frequency modulated continuous waveform. Range-Doppler processing is used to estimate the range and relative velocity of the targets based on which simulation results are numerically verified for a driving scenario.
A primary effect of palmitic acid on mouse oocytes is the disruption of the structure of the endoplasmic reticulum

Exposure of mouse oocytes to saturated fatty acids (FAs) such as palmitic acid (PA) has been shown to increase lipid content and cause an endoplasmic reticulum (ER) stress response and changes in the mitochondrial redox state. PA can also disrupt Ca2+ stores in other cell types. The links between these intracellular changes, or whether they are prevented by mono-unsaturated FAs such as oleic acid (OA), is unclear. Here, we have investigated the effects of FAs on mouse oocytes, that are maturated in vitro, using coherent anti-Stokes Raman scattering and two-photon fluorescence microscopy. When oocytes were matured in the presence of PA, there were changes in the aggregation pattern and size of lipid droplets that were mitigated by co-incubation in OA. Maturation in PA alone also caused a distinctive disruption of the ER structure. This effect was prevented by incubation of OA with PA. In contrast, maturation of mouse oocytes in medium containing PA was not associated with any significant change in the redox state of mitochondria or the Ca2+ content of intracellular stores. These data suggest that a primary effect of saturated FAs such as PA on oocytes is to disrupt the structure of the ER and this is not due to an effect on the mitochondria or Ca2+ stores.
Sequential Production of ᴅ-xylonate and Ethanol from Non-Detoxified Corncob at Low-pH by Pichia kudriavzevii via a Two-Stage Fermentation Strategy

Improving the comprehensive utilization of sugars in lignocellulosic biomass is a major challenge for enhancing the economic viability of lignocellulose biorefinement. A robust yeast Pichia kudriavzevii N-X showed excellent performance in ethanol production under high temperature and low pH conditions and was engineered for ᴅ-xylonate production without xylitol generation. The recombinant strain P. kudriavzevii N-X/S1 was employed for sequential production of ᴅ-xylonate and ethanol from ᴅ-xylose, feeding on ᴅ-glucose without pH control in a two-stage strategy of aerobic and shifting micro-aerobic fermentation. Acid-pretreated corncob without detoxification and filtration was used for ᴅ-xylonate production, then simultaneous saccharification and ethanol fermentation was performed with cellulase added at pH 4.0 and at 40 °C. By this strategy, 33.5 g/L ᴅ-xylonate and 20.8 g/L ethanol were produced at yields of 1.10 g/g ᴅ-xylose and 84.3% of theoretical value, respectively. We propose a promising approach for the sequential production of ᴅ-xylonate and ethanol from non-detoxified corncob using a single microorganism.
When does a vessel become a pipe

This paper addresses the age old question regarding the precise conditions under which the transient outflow from a punctured pipeline may be modelled as that emanating from a vessel with the result of orders of magnitude reduction in the computational run time. The above finding translated into a simple mathematical algorithm implemented in the CFD software PipeTech developed by the authors is employed by HSE and major oil and gas operators for safety assessment of pressurised pipelines. The most recent application includes the design and construction of the longest fully instrumented test pressurised pipeline in China as part of the CO2PipeHaz FP7 project coordinated by the main author (HM).
Prediction of Bias-Ply Tire Contact Area Based on Overall Unloaded Diameter, Inflation Pressure and Vertical Load Using Linear Regression Model

As deflection is a key parameter and many equations have been developed based on it to evaluate the tractive performance of radial-ply tires, this study was conducted to predict deflection ( ) of radial-ply tire based on overall unloaded diameter (d), inflation pressure (P) and vertical load (W). For this purpose, deflection of four radial-ply tires with different overall unloaded diameter were measured at five levels of inflation pressure and five levels of vertical load. Results of deflection measurement for radial-ply tires No. 1, 2 and 3 were utilized to determine regression model, and three-variable linear regression model = 77.43 - 0.078 d - 0.758 P + 3.519 P W with R = 0.985 was obtained. Also, results of deflection measurement for radial-ply tire No. 4 were used to 2 verify model. The paired samples t-test results indicated that the deflection values predicted by model were less than the deflection values measured by test apparatus. To check the discrepancies between the deflection values predicted by model with the deflection values measured by test apparatus, RMSE and MRPD were calculated. The amounts of RMSE and MRPD were 2 mm and 5.5%, respectively. Slight amounts of RMSE and MRPD confirmed that the three-variable linear regression model may be used to predict deflection of radial-ply tire based on overall unloaded diameter, inflation pressure and vertical load. On the other hand, to calculate actual deflection values or deflection values measured by test apparatus ( ) based on deflection values M predicted by model ( ) the linear regression model = 0.896 + 5.316 with R = 0.995 can be strongly P MP recommended.
Product's disassemblability evaluation using information entropy

The paper discusses major important issues in design for remanufacturing and focuses on the significance of disassembly evaluation at the design stage. In the first part of the research, various stages of design are elaborated and investigated, keeping in view the important factors responsible to ensure good remanufacturing. Then, in connection with disassembly, four important factors are identified that need to be evaluated at the design stage to facilitate remanufacturing. Then we formulate a unique evaluation system for all the four factors based on information entropy. Finally, two practical examples from existing printers are used to illustrate that the developed formulation is useful and the quantitative evaluation values are representative.
Physical Activity Dimensions Differentially Predict Physical and Mental Components of Health-Related Quality of Life: Evidence from a Sport for All Study

The present cross-sectional study aimed to investigate the relationship between different dimensions of physical activity (PA) (i.e., work, sport, leisure) and health-related quality of life (HRQoL) (i.e., overall, physical component, mental component) in an adult lifespan sample of 381 active individuals (age range: 18–88 years; 38.8% men), while controlling for important covariates in terms of sex, age, education, and health profile regarding medical history. HRQoL was assessed using the 12-item Short-Form Health Survey (SF-12). Usual (i.e., previous 12 months) PA was assessed during face-to-face interviews using the Baecke questionnaire. Hierarchical regression analyses showed in Step 1 that the three PA dimensions work, sport, and leisure (entered simultaneously) together predicted 8%, 10%, and 4% of the variance in SF-12 total score, SF-12 physical component, and SF-12 mental component, respectively. In the final model, adjusting for sex, age, education, and health profile regarding medical history, sport emerged as the only PA dimension predicting SF-12 total score and the SF-12 physical component. In conclusion, health-policy targets at the community level should include the promotion of lifelong engagement in PA, especially sport, to allow the sustainability of HRQoL across the lifespan of our society.
Substitute Behaviors following Residential Substance Use Treatment in the Western Cape, South Africa

The dynamics of substitute behaviors and associated factors remain poorly understood globally, and particularly in low- and middle-income contexts. This prospective study describes the prevalence and types of substitute behaviors as well as predictors, correlates, and motivations associated with substitution in persons (n = 137) admitted to residential substance use treatment in the Western Cape province of South Africa. The brief assessment of recovery capital, overall life satisfaction scale, and an adapted version of the addiction matrix self-report measure were completed during and post-treatment. Results indicate that substitutes were employed consciously for anticipated appetitive effects, for time-spending, (re)connecting with others, and enjoyment. At follow-up, 36% of service users had substituted their primary substance(s) with another substance or behavior; 23% had relapsed and 40% had maintained abstinence. While some service users may be especially vulnerable to developing substitute behaviors, targeted prevention and intervention efforts can reduce this risk.
Low-Loss Analog and Digital Reflection-Type MEMS Phase Shifters With 1  :  3 Bandwidth

Broad-band analog and digital reflection-type phase shifters (RTPSs), showing constant phase shift over 1:3 bandwidth, have been developed using microelectromechanical systems (MEMS) technology. Two-unit RTPSs centered at two different frequencies have been cascaded to achieve flat phase responses over a wide frequency band. Each phase shifter uses air-gap overlay coplanar-waveguide couplers for low-loss 3-dB coupling and bridge-type MEMS capacitors for reflective terminations. The fabricated analog phase shifter shows the average insertion loss of 3.5 dB, and maximum phase error of /spl plusmn/4.9/spl deg/ from 15 to 45 GHz. The 2-bit digital RTPS shows reduced maximum phase error of /spl plusmn/2.8/spl deg/ together with a comparable insertion loss of 3.1 dB from 5 to 15 GHz. The details of the circuit design, analysis, and fabrication procedures are presented together with the measurement results. Compared with the similar constant phase shifters using semiconductor diodes and transistors, the micromachined RTPS of this study shows superior performance in terms of phase errors, insertion losses, and bandwidth.
Unified dispersion model for multilayer microstrip line

A unified dispersion model is presented to calculate frequency dependent dielectric constant for a multilayer microstrip line. The model is a combination of the transverse transmission line (TTL) method, the method for the reduction of multilayer structures to an equivalent single layer microstrip line, and the dispersion model of M. Kirschning and R.H. Jansen (1982). The result of the model has been confirmed within an accuracy of 1% against the results from SDA, ESDT, and MM, i.e., various forms of full wave analysis. These results have been confirmed between 2 GHz and 18 GHz. The present model is suitable for use in a CAD package for MIC, MMIC, and printed antenna design. >
Performance in the Glittre-ADL Test is Associated with the Pulmonary Function of Patients with Chronic Obstructive Pulmonary Disease

Abstract The relationship between lung function and performance in some functional tests, as the six-minute walk test (6MWT) and Glittre-ADL test (TGlittre) are still discrepant in patients with chronic obstructive pulmonary disease (COPD). This study aimed to verify which test better correlates and is better explained by the pulmonary function, and which test better discriminates patients regarding the severity of the disease. Seventy-four patients with moderate to very severe COPD (54 men; 66 ± 9 years; FEV1: 37.2 ± 14.3%pred) were included. Spirometry, 6MWT and TGlittre were performed. The results showed weak to moderate correlation between pulmonary function variables and 6MWT (0.36 ≤ r ≤ 0.45) and TGlittre (−0.44 ≤ r ≤ −0.53). In patients with performance of ≤400 m in the 6MWT, a strong correlation was observed between TGlittre with FEV1 (%pred) (r = −0.82; p < .001). The pulmonary function variable that better predict the functional tests performance was FEV1 (R 2 = 0.17). Both functional tests were able to discriminate patients with COPD GOLD 4 from the other classifications. When compared to GOLD 2 patients, GOLD 4 patients presented higher time spent on TGlittre (p < .001). When compared to GOLD 3 patients, GOLD 4 patients had higher TGlittre (p = .001). No statistical differences were found in the 6MWT between GOLD 3 and 4, as well as between GOLD 2 and 3. In conclusion, the pulmonary function presents stronger correlations and better explain the variability of TGlittre than of the 6MWT, especially in patients with greater functional impairment. The TGlittre seems to better discriminate patients with COPD regarding the severity of lung function.

Optical control of the coupling characteristics of parallel guide directional couplers in image guide technology is investigated experimentally in suppression mode at W‐band. Compared with previous designs, the control range of coupling versus illumination intensity is significantly increased because of a symmetric layout of the active section in dark state. © 2010 Wiley Periodicals, Inc.

A Cost-Effective Antenna-in-Package Design With a 4 × 4 Dual-Polarized High Isolation Patch Array for 5G mmWave Applications

A cost-effective antenna-in-package design based on a 4 × 4 dual-polarized high isolation patch array for 5G mmWave applications is proposed in this paper. To obtain a cost-effective design, we devised a four-layer metal stack-up structure with dielectric materials consisting of one TLY-5 polytetrafluoroethylene (PTFE) and two FR-4 epoxies. The devised stack-up exhibits a simple and compact geometry due to the small number of layers, which allows the design to be manufactured using a low-priced standard printed-circuit-board process. Additionally, the employed material combination in the stack-up design possesses a high-end PTFE only in the region with the antenna radiators, which enables good antenna radiation performance at an affordable price. In addition, to design a high-isolation patch array for dual-polarized applications using the low-layer stack-up structure, we employed capacitive probes, defected ground structures, and the rotated-fed method in the proposed array design. With these techniques, the designed array exhibited excellent performance with respect to both port-to-port isolation and cross-polarization isolation. The mechanism of improvement in port-to-port isolation was clearly described using the established equivalent circuit model of the proposed structure. As a result, the fabricated antenna-in-package has the reflection coefficients of less than –10 dB in the targeted frequency range of 26.5–29.5 GHz and has a peak gain of 17.37 dBi at 28 GHz. The measured port-to-port isolations and cross-polarization isolations are higher than 22.63 and 30 dB in the targeted frequency band, respectively.
