Underlying Subwavelength Aperture Architecture Drives the Optical Properties of Microcavity Surface Plasmon Resonance Sensors
Authors: Amarie Dragos , Mosavian Nazanin , Waters Elijah L. , Stupack Dwayne G.
Published: August 2020

Microcavity surface plasmon resonance sensors (MSPRSs) develop out of the classic surface plasmon resonance technologies and aim at producing novel lab-on-a-chip devices. MSPRSs generate a series of spectral resonances sensitive to minute changes in the refractive index. Related sensitivity studies and biosensing applications are published elsewhere. The goal of this work is to test the hypothesis that MSPRS resonances are standing surface plasmon waves excited at the surface of the sensor that decay back into propagating photons. Their optical properties (mean wavelength, peak width, and peak intensity) appear highly dependent on the internal morphology of the sensor and the underlying subwavelength aperture architecture in particular. Numerous optical experiments were designed to investigate trends that confirm this hypothesis. An extensive study of prior works was supportive of our findings and interpretations. A complete understanding of those mechanisms and parameters driving the formations of the MSPRS resonances would allow further improvement in sensor sensitivity, reliability, and manufacturability.
Chemiluminescent Optical Fiber Immunosensor Combining Surface Modification and Signal Amplification for Ultrasensitive Determination of Hepatitis B Antigen
Authors: Xu Xuexue , Nie Rongbin , Huang Jingwen , Yang Li
Published: August 2020

Optical fiber based immunosensors are very attractive for biomarker detection. In order to improve the sensor response, we propose a promising strategy which combines porous-layer modification of the fiber surface and streptavidin-biotin-peroxidase nano-complex signal amplification in chemiluminescent detection. Two hepatitis B antigens, hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg), are used as the targets for analysis using the proposed sensor. Comparing to immunoassays using normal optical fiber sensors, the response of the present sensor is enhanced by a factor of 4.8 and 6.7 for detection of HBsAg and HBeAg, respectively. The limit-of-quantitation of the proposed method is as low as 0.3 fg/mL (0.01 fg/mL) with a wide linear response range of 3 fg/mL–150 ng/mL (0.1 fg/mL–160 ng/mL) for sensing HBsAg (HBeAg). Quantitative determination of HBsAg and HBeAg in human serum samples is performed, showing the applicability of the proposed method for biomarker detection.

Authors: Chen Rongjun , Yu Yongxing , Chen Jiangtao , Zhong Yongbin , Zhao Huimin , Hussain Amir , Tan Hong-Zhou
Published: August 2020

With the development of commodity economy, the emergence of fake and shoddy products has seriously harmed the interests of consumers and enterprises. To tackle this challenge, customized 2D barcode is proposed to satisfy the requirements of the enterprise anti-counterfeiting certification. Based on information hiding technology, the proposed approach can solve these challenging problems and provide a low-cost, difficult to forge, and easy to identify solution, while achieving the function of conventional 2D barcodes. By weighting between the perceptual quality and decoding robustness in sensing recognition, the customized 2D barcode can maintain a better aesthetic appearance for anti-counterfeiting and achieve fast encoding. A new picture-embedding scheme was designed to consider 2D barcode, within a unit image block as a basic encoding unit, where the 2D barcode finder patterns were embedded after encoding. Experimental results demonstrated that the proposed customized barcode could provide better encoding characteristics, while maintaining better decoding robustness than several state-of-the-art methods. Additionally, as a closed source 2D barcode that could be visually anti-counterfeit, the customized 2D barcode could effectively prevent counterfeiting that replicate physical labels. Benefitting from the high-security, high information capacity, and low-cost, the proposed customized 2D barcode with sensing recognition scheme provide a highly practical, valuable in terms of marketing, and anti-counterfeiting traceable solution for future smart IoT applications.
Optimization of Sparse Cross Array Synthesis via Perturbed Convex Optimization
Authors: Gu Boxuan , Chen Yaowu , Jiang Rongxin , Liu Xuesong
Published: August 2020

Three-dimensional (3-D) imaging sonar systems require large planar arrays, which incur hardware costs. In contrast, a cross array consisting of two perpendicular linear arrays can also support 3-D imaging while dramatically reducing the number of sensors. Moreover, the use of an aperiodic sparse array can further reduce the number of sensors efficiently. In this paper, an optimized method for sparse cross array synthesis is proposed. First, the beamforming of a cross array based on a multi-frequency algorithm is simplified for both near-field and far-field. Next, a perturbed convex optimization algorithm is proposed for sparse cross array synthesis. The method based on convex optimization utilizes a first-order Taylor expansion to create position perturbations that can optimize the beam pattern and minimize the number of active sensors. Finally, a cross array with 100 + 100 sensors is employed from which a sparse cross array with 45 + 45 sensors is obtained via the proposed method. The experimental results show that the proposed method is more effective than existing methods for obtaining optimum results for sparse cross array synthesis in both the near-field and far-field.
The Optimization of Energy Recovery Device Sizes and Locations in Municipal Water Distribution Systems during Extended-Period Simulation
Authors: Bonthuys Gideon Johannes , van Dijk Marco , Cavazzini Giovanna
Published: August 2020

Excess pressure within water distribution systems not only increases the risk for water losses through leakages but provides the potential for harnessing excess energy through the installation of energy recovery devices, such as turbines or pump-as-turbines. The effect of pressure management on leakage reduction in a system has been well documented, and the potential for pressure management through energy recovery devices has seen a growth in popularity over the past decade. Over the past 2 years, the effect of energy recovery on leakage reduction has started to enter the conversation. With the theoretical potential known, researchers have started to focus on the location of energy recovery devices within water supply and distribution systems and the optimization thereof in terms of specific installation objectives. Due to the instrumental role that both the operating pressure and flow rate plays on both leakage and potential energy, daily variation and fluctuations of these parameters have great influence on the potential energy recovery and subsequent leakage reduction within a water distribution system. This paper presents an enhanced optimization procedure, which incorporates user-defined weighted importance of specific objectives and extended-period simulations into a genetic algorithm, to identify the optimum size and location of potential installations for energy recovery and leakage reduction. The proposed procedure proved to be effective in identifying more cost-effective and realistic solutions when compared to the procedure proposed in the literature.

Authors: Kruglova Antonina , Kesulahti Jenni , Minh Le Khoi , Gonzalez-Martinez Alejandro , Mikola Anna , Vahala Riku
Published: August 2020

In this study, the microbial community of nitrifying activated sludge adapted to Finnish climate conditions was studied to clarify the microbial populations involved in low-temperature nitrification. Microbial community analysis of five full-scale wastewater treatment plants (WWTPs) showed several differences compared to WWTPs from other countries with a similar climate. In particular, very low abundance of ammonium oxidizing bacteria (AOBs) (altogether ˂ 0.25% of total community) as well as typical NOBs (˂0.35%) and a high abundance of orders Cytophagales and Micrococcales was observed in all Finnish WWTPs. To shed light on the importance of autotrophic and heterotrophic nitrifying processes, laboratory studies of activated sludge were carried out with a presence of and a lack of organic carbon in wastewater at 10 ± 1 °C. Two different sludge retention times (SRTs) were compared to determine the effect of this operational parameter on low-temperature nitrogen removal. The important role of previously reported Candidatus Nitrotogaarctica for nitrite oxidizing in cold climate conditions was confirmed in both full-scale and laboratory scale results. Additionally, potential participation of Dokdonella sp. and Flexibacter sp. in nitrogen removal at low-temperatures is proposed. Operation at SRT of 100 days demonstrated more stable and efficient nitrogen removal after a sharp temperature decrease compared to 14 days SRT.
Quality and Efficacy of the Provided Medial Services as Key Factors for Improving Competitiveness of the Healthcare Institutions
Authors: Shakhabov Islam , Melnikov Yuriy , Smyshlyayev Aleksey
Published: August 2020

Many researchers mix up the ratios of medical services quality and efficacy. There is no unified methodology for the medical services quality assessment. The quality and efficacy of the medical services provided are the key indicators of their compatibility in the market. These indicators may not absolutely correlate with real indicators of the quality and efficacy of the medical services. They may not depend on the high value of the medical services for direct and indirect consumers of the medical services. The medical services quality and efficacy are usually considered as some single and inseparably peculiar characteristic. At the same time, there may appear a situation when the service is effective but not qualitative, or vice versa.

Russia in international ratings and the impact of coronavirus on its economy
Authors: Rakhaeva V. , Mizyureva V.
Published: August 2020

In the spring of 2020, the Russian economy, like the economies of many countries of the world, underwent a serious test. The losses and consequences of this test are largely determined by the stability of the economy, the stability of institutions, the presence or absence of systemic problems. In this article, the authors focus on the main problems of the Russian economy and how they are aggravated by the pandemic. Different models of government support for the economy are used in different countries with different levels of economic development, social and economic priorities. The most important task of the state in Russia in the short term is to implement measures aimed at combating the collapsed problems in connection with the pandemic: competent support for the financial and real sectors, the population and the social sphere. In the long term, in order to ensure economic growth, it is necessary to focus on solving the following identified problems: the raw materials dependence of the Russian economy, the low quality of economic growth, the decline in real incomes of the population, the uneven level of technological development of industries and regions, and the lack of macroeconomic stability. The presence of these problems made the Russian economy even more vulnerable to the negative impact of force majeure and increased the relevance of their solution.

«NO FUE UN GOLPE; FUE UN ALZAMIENTO.» ANÁLISIS Y PERSPECTIVAS SOBRE LA VÍA CHILENA AL SOCIALISMO DESDE LAS PÁGINAS DE REVISTA FUERZA NUEVA (1970-1973)
Authors: Morales Aguilera Francisco Javier
Published: August 2020

Este artículo indaga en la perspectiva y posicionamiento de la revista nacionalista española Fuerza Nueva en relación al gobierno de la Unidad Popular entre los años 1970-1973. El análisis del contenido se realizó a partir de una revisión exhaustiva de los casi cincuenta artículos que se publicaron sobre la experiencia socialista chilena en dicho periodo. La mayor parte de las ideas y opiniones que se expresaron al respecto se articularon en torno a un tópico más o menos transversal que identificaba a dicho gobierno y su proyecto de transformación estructural como un caso inequívoco de expansión del comunismo soviético por América Latina. Esta mirada, además de mostrar un férreo posicionamiento anticomunista revelaría también un intento por homologar parte de la realidad chilena de entonces al contexto de la España de la década de los treinta, de modo de hacer una lectura interconectada entre ambas experiencias.

LAS RELACIONES ENTRE EL KOMINTERN Y PARTIDO COMUNISTA CHILENO (1922-1941)
Authors: Grez Sergio
Published: August 2020

Este artículo indaga los vínculos entre la Internacional Comunista (Komintern) y el Partido Comunista de Chile (PCCh) desde 1922 hasta 1941 a partir de las siguientes hipótesis. Entre 1927 y 1935 el PCCh sufrió dos rupturas mayores, tanto en los contenidos de su política nacional como en la relación con la Internacional. El primer quiebre, entre 1927 y 1933, significó el paso de una extraordinaria autonomía política a una sujeción prácticamente absoluta a los diferentes órganos komintereanos que, a través de una ruda intromisión trataron de convertirlo en un simple ejecutante de sus decisiones inspiradas por la política de “clase contra clase”. El paso a la política frentepopulista en 1935 permitió al partido chileno mayores márgenes de autonomía frente a la Internacional Comunista. Aunque la relación con el Komintern se mantendría –en lo esencial– en los términos establecidos a comienzos de la década, los éxitos del partido chileno y el eclipse del Buró Sudamericano (BSA) de la Internacional, permitirían al PCCh un margen de acción algo menos asfixiante por parte de los organismos komintereanos.

Mitigating a traffic impact on animals
Authors: Nowacka Dagmara
Published: August 2020

Poland, which biological diversity stands out in comparison with the rest of Europe, became one of the biggest road construction site during the last few years. A development of a road network almost always involves disturbance of biogically sensitive and protected areas. As those areas cover about one third of the whole country it is virtually impossible to avoid conflicts concerning biological protection. For those reasons, steps to be taken to limit to a minimum the incidence of the construction works on the biological environment constitute an integral part of each investment. The costs of protecting unspoiled environment represent up to 30% of the total costs of investments. The effectiveness of planned actions must consequently justify spending the considerable funds involved. Monitoring of the results of solutions used allows both verification of their usefulness and identification possible errors so that they may be avoided in the future. Number of actions which have been undertaken in Poland to minimalize the incidence of roads on unspoiled environment, in particular as regards the number of fauna passes, to preserve the ecological continuity, place Poland among most advanced European countries.
The impact of land development on the distribution of road noise level on the surface of the upper wildlife crossings
Authors: Sołowczuk Alicja
Published: August 2020

The Environmental Protection concerns mainly the fauna, because the development of communication and the construction of new transport routes has been increasingly fragmenting the natural environment. To fix the errors, arising from the fragmentation of the natural environment, upper or lower crossings are built for animals. The upper crossings are very expensive because of their di­mensions. The construction of the upper crossings does not always turn out to be functional, as badly developed surfaces are not attractive to animals, which do not use them. The proper management of the upper crossings area is a very difficult issue, still quite experimental. In the literature, no functional solutions can be found in this regard. The only guidelines for designers may be the examples of the area development of the existing crossings, whose functionality was confirmed by the data from monitoring. However, ready solutions from other roads and natural conditions are not always useful, because in most cases the crossings should be tailored to the wildlife which use them. The paper presents various development elements, together with the results of noise analyzes, confirming the impact of the development, depending on its type, on the ”achieved status of soundproofness” on the access to the crossings and their surface.

Published: August 2020

The paper presents the methods to improve safety and quality of life of people living in the neighborhood of roads and the situation of road users by means of traffic calming. The focus is kept on positive impact of traffic calming measures on acoustic climate in the surrounding of roads. The paper also contains the characteristics of selected impacts of road traffic on the environment together with a general outline of traffic calming as an instrument to mitigate the negative influence. Various possibilities to frame the acoustic climate and reduce transport-related inconvenience by means of different traffic calming methods are present as well. Then a case study (regional road No 824 in Puławy) is used to assess the effectiveness of specific solutions of comprehensive traffic calming with regard to speed reduction and abatement of noise emissions. Analyses are based on measurements’ results (traffic volumes, driving speeds and noise levels) and on acoustic calculations performed by the authors as part of their own study (internal research & development program of EKKOM). On the basis of measurements’ results and calculations the paper also addresses the problem of lack of correction factors related to traffic calming in the calculation model and the one of errors in noise modeling while preparing the case study.

PENGAWASAN KOLABORATIF DALAM PELAKSANAAN KEBIJAKAN BANTUAN SOSIAL TERDAMPAK COVID-19
Authors: Herdiana Dian
Published: August 2020

Kebijakan bantuan sosial bagi masyarakat terdampak COVID-19 secara empiris mengalami masalah yaitu adanya kesalahan data Rumah Tangga Sasaran (RTS), implikasinya banyak warga masyarakat yang seharusnya berhak namun tidak menerima bantuan sosial, sebaliknya warga yang mampu justru mendapatkan bantuan sosial. Didasarkan kepada permasalahan tersebut maka dibutuhkan pengawasan kolaboratif yang dilakukan oleh berbagai pihak guna memastikan kebijakan tersebut berjalan sebagaimana tujuan awal. Artikel ini menggunakan pendekatan kualitatif dengan metode analisis deskriptif, pengumpulan data menggunakan data sekunder dari berbagai sumber yang relevan seperti buku, jurnal, peraturan perundang-undangan, laman web dan lainnya. Hasil penelitian menunjukan bahwa belum adanya upaya pengawasan yang dilakukan secara kolaboratif terhadap pelaksanaan kebijakan bantuan sosial dalam rangka perlindungan masyarakat terdampak COVID-19, proses pengawasan dilaksanakan dengan menggunakan model pengawasan internal secara tertutup yang mana pihak lain termasuk masyarakat tidak memiliki akses untuk melakukan pengawasan tersebut. Berdasarkan kepada hal tersebut diperlukan upaya rekonstruksi model pengawasan pelaksanaan kebijakan bantuan sosial yang memungkinkan adanya kolaborasi antar pemangku kepentingan bidang pengawasan guna menghasilkan sistem pengawasan yang integratif dan sinergis.
