Authors: Yan Bo , Sun Guoxiang 
Published: August 2017

AbstractLiuwei Dihuang Pill, a classical traditional Chinese medicine, has been widely used to treat kidney yin deficiency in China for hundreds of years. Little attention, however, has been paid to quality control methods for this formulation. In the present study, we aimed to establish a comprehensive and practical quality evaluation system for Liuwei Dihuang Pill. Thus, ultraviolet spectroscopic fingerprints and multi‐wavelength fusion fingerprints have been proposed for quality consistency evaluation of the popular patent. The similarity analysis of Liuwei Dihuang Pill samples was evaluated by systematic quantitative fingerprint method from qualitative and quantitative perspectives. The results showed that 26 batches of samples were classified into five grades for fusion fingerprints and three grades for ultraviolet spectroscopic fingerprints. Moreover, the fingerprint–efficacy correlation was also established and confirmed through the partial least squares model to visualize the antioxidant activity of Liuwei Dihuang Pill in vitro. In conclusion, these results indicated that integrating ultraviolet spectroscopic fingerprints and multi‐wavelength fusion fingerprints coupled with antioxidant activities provide a rapid and effective approach to monitor the quality consistency of Liuwei Dihuang Pill.

AbstractSalmonella enterica subspecies enterica serovar Typhimurium is the most common zoonotic pathogen in Bulgaria. To allow efficient outbreak investigations and surveillance in the food chain, accurate and discriminatory methods for typing are needed. This study evaluated the use of multiple‐locus variable‐number of tandem repeats analysis (MLVA) and compared results with antimicrobial resistance (AMR) determinations for 100 S. Typhimurium strains isolated in Bulgaria during 2008–2012 (50 veterinary/food and 50 human isolates). Results showed that isolates were divided into 80 and 34 groups using MLVA and AMR, respectively. Simpson's index of diversity was determined to 0.994 ± 0.003 and 0.945 ± 0.012. The most frequently encountered MLVA profiles were 3‐11‐9‐NA‐211 (n = 5); 3‐12‐9‐NA‐211 (n = 3); 3‐12‐11‐21‐311 (n = 3); 3‐17‐10‐NA‐311 (n = 3); 2‐20‐9‐7‐212 (n = 3); and 2‐23‐NA‐NA‐111 (n = 3). No clustering of isolates related to susceptibility/resistance to antimicrobials, source of isolation, or year of isolation was observed. Some MLVA types were found in both human and veterinary/food isolates, indicating a possible route of transmission. A majority (83%) of the isolates were found to be resistant against at least one antimicrobial and 44% against ≥4 antimicrobials. Further studies are needed to verify MLVA usefulness over a longer period of time and with more isolates, including outbreak strains.
Usage of multicriteria decision‐making support arsenal for strategic planning in environmental protection sphere

Published: August 2017

AbstractThis paper outlines an approach to strategic planning, based on decision‐making support methods. It provides a description of a step‐by‐step procedure, allowing the decision maker to build a strategy, targeted at solution of some weakly structured problem or at achievement of some complex goal, influenced by multiple tangible and intangible criteria. Criteria are formulated by experts and arranged into a hierarchy, as prescribed by the analytic hierarchy process. Relative weights of criteria are calculated on the basis of expert estimates, using the combinatorial approach, which is, in a way, an extension of analytic hierarchy process toolkit. In the context of this paper, a strategy is defined as the optimal way of currently available resource distribution among specific factors or projects, which influence the main goal of a strategic plan. Each project is characterized by certain funding volume constraints (minimum and maximum resource amounts) as well as time frames (launching and completion or termination dates). As an example of implementation of our approach, we consider a case of resource distribution among environmental projects.

AbstractBackgroundThe extent to which participants act to clinically verify research results is largely unknown. This study examined whether participants who received Lynch syndrome (LS)‐related findings pursued researchers’ recommendation to clinically verify results with testing performed by a CLIA‐certified laboratory.MethodsThe Fred Hutchinson Cancer Research Center site of the multinational Colon Cancer Family Registry offered non‐CLIA individual genetic research results to select registry participants (cases and their enrolled relatives) from 2011 to 2013. Participants who elected to receive results were counseled on the importance of verifying results at a CLIA‐certified laboratory. Twenty‐six (76.5%) of the 34 participants who received genetic results completed 2‐ and 12‐month postdisclosure surveys; 42.3% of these (11/26) participated in a semistructured follow‐up interview.ResultsWithin 12 months of result disclosure, only 4 (15.4%) of 26 participants reported having verified their results in a CLIA‐certified laboratory; of these four cases, all research and clinical results were concordant. Reasons for pursuing clinical verification included acting on the recommendation of the research team and informing future clinical care. Those who did not verify results cited lack of insurance coverage and limited perceived personal benefit of clinical verification as reasons for inaction.ConclusionThese findings suggest researchers will need to address barriers to seeking clinical verification in order to ensure that the intended benefits of returning genetic research results are realized.
A wideband single‐layer crossover using substrate integrated waveguide to grounded coplanar waveguide transition
Authors: Bagheri Alireza , Moradi Gholamreza 
Published: August 2017

AbstractThis letter presents a wideband planar crossover for application in circuits based on substrate integrated waveguide (SIW). The proposed structure uses SIW to grounded coplanar waveguide (GCPW) transition, which facilitates crossing of two waves in the same substrate without considerable leakage. The coplanar waveguide (CPW) is used in the core part of this crossover, which provides a high isolation. GCPW lines are tapered and connected to CPW lines, resulting in a wideband matching. The proposed design has been verified via full wave electromagnetic simulation and experimental test. The crossover dimensions with SIW excitation is 40 mm × 40 mm and its isolation across 9–18 GHz band is more than 20 dB.

Size‐reduction balanced UWB BPF design using meander slotline and its mirror structure with the microstrip feed
Authors: Ho Min‐Hua , Hong Wanchu , Chang Geng‐Gui 
Published: August 2017

AbstractThe contribution of this work is to propose a size‐reduction design of a balanced UWB BPF using a meander slotline together with its mirror structure. The size reduction is accomplished by meandering the slotline. The proposed circuit is excited by a vertically oriented feeding microstrip. The meander slotline combined its mirror one exhibits a wideband response as well as the one of an ordinary slotline. However, the former together with the microstrip feed, which perfectly preserves the structural symmetry, has a much smaller circuit size. This structural symmetry of the circuit renders itself suitable in the balanced circuit design. Thus, a smallest balanced UWB BPF in the slotline‐alike structure category is realized.

Authors: Wu Bian , Xu Yang , Wu Yufeng , Zhang Xiuyin 
Published: August 2017

AbstractA tunable dual‐band filtering power divider with constant bandwidth and high selectivity is proposed, which incorporates a wideband power divider with two tunable dual‐band filters. The filter provides a tunable dual‐mode dual‐band filtering response, and realizes a 90° phase shift to replace the middle quarter wavelength transmission line. As the bias voltage increases, the lower band increases from 1.1 to 1.5 GHz with a constant bandwidth of 40 MHz, while the higher band remains at 2.17 GHz with a fixed bandwidth of 60 MHz. During the wide tuning range, the return loss and isolation are always >15 dB, with a high selectivity due to multiple transmission zeros.

Authors: Rasekhmanesh Mohammad Hosein , Piroutiniya Asrin , Mohammadi Pejman 
Published: August 2017

AbstractIn this article, a 2 × 2 circular polarized (CP) antenna array, which is using sequential rotation (SR) technique in feeding network, has been introduced. The feeding network uses two 90° arcs and several rectangular lines with the same width. The length of these elements is multiple of λg/4 to produce 90° phase difference in 4 outputs of feeding network. By connecting the patch elements to the feeding network, which have been surrounded with radiating patch elements, design of 2 × 2 patch array has been completed. This array antenna with an incomplete ground which helps to have a better impedance matching, has been caused to reach a wider axial ratio (AR) and impedance bandwidth. The prototype of the proposed antenna array is built to validate the antenna performance. By using these techniques, a common bandwidth of 1.15 GHz has been achieved for impedance bandwidth (S11 < 10 dB) and AR bandwidth (AR < 3 dB) and 7.5 dBi maximum gain. In addition, the gain is more than 4 dBi in desired frequency range. According to the frequency range of 2.8‐3.95 GHz, the proposed antenna is suitable for S‐band applications.

Size reduction and harmonic suppression in branch line couplers implemented by means of capacitively loaded slow‐wave transmission lines
Authors: Coromina Jan , Selga Jordi , Vélez Paris , Bonache Jordi , Martín Ferran 
Published: August 2017

AbstractA systematic approach for the design of compact branch‐line hybrid couplers with harmonic suppression is proposed in this article. The couplers are implemented by means of slow‐wave artificial transmission lines based on patch capacitors. It is shown in this article that the number of unit cells of the artificial lines should not be arbitrary. Specifically, it is demonstrated that to efficiently suppress the harmonic bands of the coupler and simultaneously keep the response of the coupler unaltered in the region of interest, two unit cells are required. Based on the proposed design methodology, a compact branch line coupler with 46% size, as compared to the ordinary counterpart, and efficient rejection of the first and second harmonic bands, is reported in this article. The designed coupler exhibits good performance in the region of interest, very similar to one of the conventional coupler.

Simplified design, simulation, and lab‐environment measurement scheme for retro‐directive antenna arrays
Authors: Hannan Abdul , Hasan Azhar , Tarar Munir Ahmad 
Published: August 2017

AbstractRetro‐directive antenna arrays are capable to reflect back an incoming signal in source direction just like corner reflectors. Retro‐directive antenna arrays do not use complex and expensive phase shifters or smart antennas to steer their beam. These arrays steer beam autonomously in source direction by reversing progressive phase induced by incident signal. Two basic designs of retro‐directive antenna array are Van Atta array and Phase Conjugating array. A simplified design for phase conjugating array is proposed in this article. Moreover, RF measurement and testing in Lab environment need special schemes to cater for issues of multipath, far field reflections, and mutual interference. Therefore, a specially designed lab environment testing methodology is proposed and validation of retro‐directive response of developed phase conjugating array using proposed testing methodology is also presented in the article.

Published: August 2017

AbstractThe prediction of thermal comfort in smart buildings is addressed in this article to support the energy manager in the management of the heating, ventilation, and air conditioning systems. An efficient control is fundamental to meet the user satisfaction as well as the energy cost reduction. The proposed method based on a customized support vector regression technique predicts and suggests to the energy managers the indoor target temperature required to obtain the desired comfort throughout the building. A network of low‐cost wireless sensors has been deployed to measure the indoor conditions of a real indoor scenario. The prediction performance has been experimentally validated and the obtained results have pointed out a temperature prediction error lower than 1°C and the achievement of the thermal comfort requirements.

Published: August 2017

A novel nanomaterial, montmorillonite–melamine cyanurate (MMT‐MCA), was successfully synthesized, in which the number of MCA layers in between 2 MMT layers can be controlled at 1 or a very large value (over 100 nm thick). Its interdigitated crystalline structure was thoroughly characterized. The MMT‐MCA shows outstanding dispersion ability in different polymers to easily prepare MMT nanocomposites by melt blending due to the π‐π stacking exfoliation between MCA layers. The paper opens the way to the synthesis of novel interdigitated nanomaterials.
