Controllable discrete Talbot self-imaging effect in Hermitian and non-Hermitian Floquet superlattices
Authors: Zhan Kaiyun , Dou Lichao , Kang Xinyue , Liu Bing
Published: September 2022

We investigate the discrete Talbot self-imaging effect in Floquet superlattices based on a mesh of directional couplers with periodically varying separation between waveguides, both theoretically and numerically. The modulated discreteness of the lattices sets strong constraints to ensure the Talbot effect generation. We show that discrete Talbot effect occurs only if the incident periods are N = 1, 2, and 4 in dispersive regimes of the Hermitian superlattices. In both dynamic localized and rectification regimes, self-imaging effect can occur for arbitrary input period N. For the rectification case, Talbot distance equals the input period. In the regime of dynamical localization, the Talbot distance remains unchanged irrespective of the pattern period. For non-Hermitian Floquet superlattices, due to the non-zero imaginary part of quasi-energy spectrum arising at the center of the Brillouin zone, where the mode degeneracy occurs, Talbot revival is not preserved when the input period is an even number, and exists only as N = 1 in the dispersive regime. The theoretical calculations and numerical simulations verify each other completely.

Optical coherence tomography angiography (OCTA) images suffer from inevitable micromotion (breathing, heartbeat, and blinking) noise. These image artifacts can severely disturb the visibility of results and reduce accuracy of vessel morphological and functional metrics quantization. Herein, we propose a multiple wavelet-FFT algorithm (MW-FFTA) comprising multiple integrated processes combined with wavelet-FFT and minimum reconstruction that can be used to effectively attenuate motion artifacts and significantly improve the precision of quantitative information. We verified the fidelity of image information and reliability of MW-FFTA by the image quality evaluation. The efficiency and robustness of MW-FFTA was validated by the vessel parameters on multi-scene in vivo OCTA imaging. Compared with previous algorithms, our method provides better visual and quantitative results. Therefore, the MW-FFTA possesses the potential capacity to improve the diagnosis of clinical diseases with OCTA.

Published: September 2022

A novel photonic-assisted 2-D Terahertz beam steering chip using only two tuning elements is presented. The chip is based on an array of three leaky wave antennas (LWAs) with a monolithically integrated beamforming network (BFN) on a 50 µm-thick indium phosphide substrate. The THz beam angle in elevation (E-plane) is controlled via optical frequency tuning using a tunable dual-wavelength laser. An optical delay line is used for azimuth (H-plane) beam control. The simulated beam scanning range is 92° in elevation for a frequency sweep from 0.23 THz to 0.33 THz and 69.18° in azimuth for a time delay of 3.6 ps. For the frequency range from 0.26 THz to 0.32 THz, it is confirmed experimentally that the THz beam scans from −12° to +33°, which is in good agreement with the numerical simulations. The beam direction in azimuth scans with a total angle of 39° when applying a delay difference of 1.68 ps. A good agreement is found between theoretically predicted and experimentally determined THz beam angles with a maximum angle deviation below 5°. The experimental scanning angles are limited due to the mechanical constraints of the on-wafer probes, the on-chip integrated transition and the bandwidth of the THz receiver LNA. The mechanical limitation will be overcome when using a packaged chip.
Indoor 3D NLOS VLP using a binocular camera and a single LED
Authors: Huang Tianming , Lin Bangjiang , Ghassemlooy Zabih , Jiang Ningcong , Lai Qiwei
Published: September 2022

In this paper, we propose a non-line of sight (NLOS) visible light positioning (VLP) system using a binocular camera and a single light emitting diode (LED) for the realization of 3D positioning of an arbitrary posture. The proposed system overcomes the challenges of the shadowing/blocking of the line of sight (LOS) transmission paths between transmitters and receivers (Rxs) and the need for a sufficient number of LEDs that can be captured within the limited field of view of the camera-based Rx. We have developed an experimental testbed to evaluate the performance of the proposed system with results showing that the lowest average error and the root mean square error (RMSE) are 26.10 and 31.02 cm following an error compensation algorithm. In addition, a label-based enhanced VLP scheme is proposed for the first time, which has a great improvement on the system performance with the average error and RMSE values of 7.31 and 7.74 cm and a 90
th
percentile accuracies of < 11 cm.
Photon confinement in a silicon cavity of an image sensor by plasmonic diffraction for near-infrared absorption enhancement
Authors: Yoshinaga Takahito , Hashimoto Kazuma , Teranishi Nobukazu , Ono Atsushi
Published: September 2022

Silicon-based image sensors are attractive for applications in the near-infrared (NIR) range owing to their low-cost and high availability. However, novel approaches are required to enhance their light absorption, hindered by the silicon band gap. In this study, we proposed a light trapping strategy in a silicon absorption layer by plasmonic diffraction and reflection within a pixel to improve the sensitivity at a specific NIR wavelength for complementary metal-oxide semiconductor image sensors. The plasmonic grating diffracted light under the quasi-resonant condition of the surface plasmon polaritons. We simulated the silicon absorption efficiency for plasmonic diffraction combined with metal-filled trenches and a pre-metal dielectric (PMD) layer. Backward propagation light in silicon by a total internal reflection at the bottom decoupled with plasmonic grating. A single SiO2 protrusion was added at the silicon bottom to prevent decoupling by scattering the light in the silicon and trapping it within the pixel. In addition, the light transmitted to the PMD layer is reflected by the wiring layer used as a mirror. The photon confinement in silicon by these constructions improved the absorption by approximately 8.2 times at an NIR wavelength of 940 nm with 3-µm-thick. It is useful for NIR imaging system with active laser illumination.

Published: September 2022

Energy-efficient devices will play a key role in the continued performance scaling of next-generation information and communications technology systems. Graphene has emerged as a key optoelectronic material with unique energy-like properties. But to the best of our knowledge, these advantages have not yet been fully exploited in optical modulators design. In this work, we design and analyze an optical modulator which is composed of two graphene layers and a ring resonator made with different amount of graphene. For performance analysis, the ring resonator’s amount of graphene is varied from 25 to 100% with four discrete steps. The critical coupling condition representing the OFF-state, and the 3-dB transmission level representing the ON-state of the device are obtained. Numerical results show this new optical modulator consumes as little energy as 4.6 fJ/bit whilst achieving a high-speed operation with a bandwidth up to 42.6 GHz when employing surprisingly only 25% of graphene. The 42.6 GHz modulator has a footprint as small as 22.1 µm2 with an active area of 1.68 µm2 only, the smallest active area to date. Alternatively, the optical modulator achieves up to ∼88.5 GHz at the expense of consuming 17.5 fJ/bit when using 100% of graphene. The proposed graphene-based modulator proved to be a compact, energy-efficient, high-speed device, useful for a myriad of applications including mobile fronthaul, telecom, and datacom.
An explorer’s journal for machines: Exploring the case of Cyberpunk 2077
Authors: Gómez-Maureira Marcello A. , Kniestedt Isabelle , Barbero Giulio , Yu Hainan , Preuss Mike
Published: September 2022

With increasing technological capabilities, video games provide ever more expansive virtual worlds for players to explore. Designers employ various mechanics and level design principles to encourage such exploration. However, what motivates people to explore in virtual environments, and which approaches are successful, is not yet clearly established. Methods for measuring player experience often take place retroactively after a play session, relying on recall, and are thus prone to missing less salient events and their motivations. Journaling events as they occur allow promises to be a suitable method of collecting data, but presents a challenge in aggregating data points due to their freeform nature. This makes it difficult to identify overarching patterns of exploration behaviour. We present an exploratory study in devising a journaling protocol for gathering information during gameplay sessions, focused on documenting moments of exploration in a manner that balances ease of data capture and data evaluation. We describe our efforts in prototyping this journaling method and how we used it to analyse Cyberpunk 2077 and several other game designs. Our results show that exploration occurs in a pattern of event → expectation → resolution. The motivation to explore depends on the expectations that a game raises through its marketing and design. At the same time, exploratory behaviour going unrewarded by the game quickly reduces the desire to explore. When recording instances of exploration, the addition of emotion words is essential in order to properly contextualize the information. This article lays the foundation for documenting exploration in games, as well as other emotional or behavioural constructs that require in-the-moment data collection.

Published: September 2022

Background and Aim: Slaughterhouses act as a significant public health hotspot in developing countries like Bangladesh. The study aimed to investigate small ruminants at slaughterhouses for pathological study and molecular detection of important zoonotic diseases.

Materials and Methods: A total of 75 goats and 14 sheep were investigated from June 2019 to January 2020 at different slaughterhouses in Mymensingh division, Bangladesh. The targeted diseases were tuberculosis (TB), listeriosis, Q fever, brucellosis, anthrax, toxoplasmosis, hydatidosis, and linguatulosis. The tentative diagnosis was made based on gross and histopathological lesions. Polymerase chain reaction (PCR) was performed to confirm the causal agents of zoonotic diseases using disease-specific primers.

Results: Grossly, caseous nodule formation in the visceral organs; enlarged and calcifications of mesenteric lymph nodes (MLNs); hydatid cyst formation in the liver were the predominant lesions observed. Histopathologically, granuloma, caseous necrosis, and calcifications admixed with acid-fast bacteria in the MLNs, liver, spleen, and kidney were seen as suggestive of infectivity due to TB. Septic lymphadenitis mixed with rod-shaped bacteria, doughnut granuloma, fibroplasia accompanied by eosinophils and lymphocytic infiltration in MLNs, and portal granuloma were observed in listeriosis, Q fever, linguatulosis, and toxoplasmosis suspected cases, respectively. The PCR amplified Mycobacterium tuberculosis complex (372 bp), Mycobacterium bovis (600 bp), Listeria monocytogenes (517 bp), Toxoplasma gondii (512 bp), and Coxiella burnetii (687 bp) species-specific amplicons. In addition, linguatulosis and hydatidosis were identified in six and three goats, respectively. Brucellosis and anthrax were not detected in any cases. The slaughterhouse samples were also found to harbor the coexistence of different zoonotic pathogens.

Conclusion: Deadly infectious zoonotic diseases in goats and sheep at slaughterhouses may cause widespread public health risks. As a result, more intensive monitoring and epidemiological surveys are required to successfully prevent and control zoonotic diseases.
On Some Convergence Properties for Finite Element Approximations to the Inverse of Linear Elliptic Operators
Authors: Kinoshita Takehiko , Watanabe Yoshitaka , T. Nakao Mitsuhiro
Published: September 2022

This paper deals with convergence theorems of the Galerkin finite element approximation for the second-order elliptic boundary value problems. Under some quite general settings, we show not only the pointwise convergence but also prove that the norm of approximate operator converges to the corresponding norm for the inverse of a linear elliptic operator. Since the approximate norm estimates of linearized inverse operator play an essential role in the numerical verification method of solutions for non-linear elliptic problems, our result is also important in terms of guaranteeing its validity. Furthermore, the present method can also be applied to more general elliptic problems, e.g., biharmonic problems and so on.
The Inventory Control Problem for a Supply Chain With a Mixed Type of Demand Uncertainty
Authors: Chausova Elena
Published: September 2022

This paper is concerned with a dynamic inventory control system described by a network model where the nodes are warehouses and the arcs represent production and distribution activities. We assume that an uncertain demand may take any value in an assigned interval and we allow that the system is disturbed by noise inputs. These assumptions yield a model with a mix of interval and stochastic demand uncertainties. We use the method of model predictive control to derive the control strategy. To deal with interval uncertainty we use the interval analysis tools and act according to the interval analysis theory. The developed results are illustrated using a numerical example.

Authors: França Leandro Luiz Silva de , Portugal José Luiz
Published: September 2022

Para corretas análises e tomadas de decisões, baseadas em dados geoespaciais, é essencial que esses dados tenham sua confiabilidade e integridade atestadas. No que se refere à Consistência Lógica, ainda são poucas as normas e pesquisas que tratem do assunto de forma sistemática, não havendo um consenso sobre os procedimentos adequados para o controle de qualidade desta categoria. Consequentemente, alguns produtores de dados geoespaciais apresentam diversas dificuldades para garantir a integridade e consistência dos seus produtos cartográficos, devido à verificação inadequada dos relacionamentos lógicos, ocasionando retrabalhos com verificações repetidas e pouco eficientes. Este artigo, portanto, teve como finalidade documentar conceitos inerentes à avaliação da consistência topológica e apresentar exemplos práticos de validação aplicados em dados reais de produção cartográfica. A aplicação desta pesquisa ocorreu em um estudo de caso para um Conjunto de Dados Geoespaciais Vetoriais (CDGV) do Projeto de Mapeamento do estado da Bahia, detalhando-se todo o procedimento metodológico para a validação topológica desses dados. Dos resultados, verificou-se uma quantidade considerável de inconsistências topológicas, indicando a necessidade de modernização dos procedimentos de validação pelos produtores de dados geoespaciais. No que se refere às contribuições deste trabalho, além da compilação de uma base teórica sobre a consistência topológica de dados geoespaciais, destaca-se também o desenvolvimento de soluções para a verificação das inconsistências com consultas SQL baseadas no software livre PostgreSQL e sua extensão espacial PostGIS.

A Infraestrutura Nacional de Dados Espaciais (INDE), foi estabelecida para a coordenação de usuários, produtores e reguladores do uso de geoinformação, denominados partes interessadas ou stakeholders. Este trabalho está concentrado na relação entre o desempenho e a carga de trabalho cognitiva com a função que o desempenha na INDE, explorando problemas de usabilidade relacionados com o acesso aos dados e metadados no geoportal. Os stakeholders foram caracterizados como usuários de dados (U), usuários e produtores de dados (UP), ou usuários, produtores e provedores de dados (UPP). A metodologia aplicada foi o questionário não moderado, dividido em perguntas do tipo abertas e fechadas que possibilitou a coleta de dados qualitativos e quantitativos. Para avaliação da carga de trabalho foi aplicado o Nasa Task Load Index (NASA-TLX). Foi perceptível que os indivíduos do grupo U apresentaram maior carga de trabalho em relação aos demais stakeholders. Este estudo possibilitou inferir que existe relação entre o desempenho nas tarefas que envolveram a utilização dos dados com a carga de trabalho e problemas de usabilidade relacionados ao acesso aos dados. O estudo contribui com evidências advindas de testes de usabilidade com usuários que interagiram com o geoportal da INDE, demonstrando que existe forte relação com a função que o stakeholder desempenha na INDE. A usabilidade variou bastante entre os perfis de usuário, sendo um indicativo que a interface do geoportal necessita de aperfeiçoamentos ou interfaces próprias construídas a partir dos conceitos do Design Centrado no Usuário, para melhor atender às necessidades específicas de cada grupo.
Generalização Cartográfica: Desafios e Perspectivas
Authors: Freiman Fabiano Peixoto , Santos Daniel Rodrigues dos
Published: September 2022

Conceitos e procedimentos relacionados ao tema de generalização cartográfica evoluíram nas últimas décadas. Originalmente, este processo era aplicado no contexto analógico para garantir a manutenção da visualização e comunicação cartográfica de forma adequada. No entanto, com o avanço da cartografia digital o paradigma é ampliado e, então, o processo é aplicado desde a concepção do produto cartográfico, ou seja, quando se deseja reduzir uma base de dados para um mínimo necessário, mas mantendo as propriedades espaciais relevantes do conjunto. Computacionalmente, as regras de generalização são expressas por meio de algoritmos computacionais que incluem aspectos de semântica e geometria, assim como exigem, além de formulações objetivas, análises subjetivas de difícil implementação e automatização. Além disso, a inserção de novas tecnologias de aquisição e processamento de dados geoespaciais produzem novas lacunas científicas a serem superadas. Nesse aspecto, este trabalho busca, a partir de uma pesquisa bibliográfica e bibliométrica, identificar como as novas tecnologias ampliam os desafios relacionados à generalização cartografia. Observa-se que, apesar dos operadores de generalização serem considerados satisfatórios, o número de publicações na temática é crescente e apresenta interesse internacional. Ademais, as novas tecnologias como algoritmos de Inteligência Artificial, aquisição de dados geoespaciais de forma incremental e construções de representações 3D inserem complexidades teóricas e práticas que devem ser superadas. Logo, os avanços da generalização cartográfica dependem da implementação de soluções relacionadas à materialização computacional dos operadores de generalização em processos objetivos que permitam a compreensão imediata da relação geométrica e estatística formada por um conjunto de dados geoespaciais.

AN EVALUATION OF GOVERNMENT SUPPORT SERVICES FOR SMMEs IN THOHOYANDOU, SOUTH AFRICA
Authors: Kelly ambe Dede , Shumba Knowledge , Zindiye Stanislous , Donga Gift
Published: September 2022

Small, Medium, and Micro Enterprises (SMMEs) possess attributes akin to entrepreneurship that make them indispensable tools for economic growth and development. While SMMEs have a direct impact on economic growth in advanced economies, these enterprises have a high failure rate due to a variety of reasons, especially during the start-up and growth phases. Government support schemes have been availed to SMMEs to assist them to survive the vulnerable phases of their existence. This study investigates the role of government support services towards the development and growth of SMMEs in South Africa. The quantitative research design used the survey method to collect data from a sample of one hundred (100) SMMEs in Thohoyandou, South Africa. The Statistical Package for Social Sciences (SPSS) was used to analyse the data, and presentation used descriptive analysis. The main study revealed that despite the government support schemes and initiatives, the failure rate of SMMEs remains high. The major factors affecting the uptake of government support schemes and initiatives included the lack of information and access to the financial assistance offered to most SMMEs through the government schemes. Despite the support schemes and initiatives, further challenges include the proliferating myriad of rules and regulations in the regulatory environment curtailing the operations and survival of SMMEs. Study findings indicated that despite the existence of the growth and development-oriented government support schemes, most SMMEs are unaware of their existence while other enterprises find them ineffective. The main conclusions point to the information deficit and needs analysis that would tailor-make and accommodate the specific requirements of different enterprises.
The evolution of virtual exchange and assessment practices
Authors: Dooly Melinda
Published: September 2022

This chapter provides a general synopsis of the evolution of Virtual
Exchange (VE) as it has progressively become more immersed in the paradigms
of language teaching approaches. Inevitably, this transformation unfolds in
pace to advances in communication technology as the interactional tools are
key for facilitating connection between distanced partners in the exchanges.
Coming full circle, these advances have had an impact on the organization of
the exchanges as well as the focus, methods, and tools used for assessing
VE. We will first foreground seminal authors’ work and their impact on VE,
next we will review the more commonplace terminology and how these terms
have evolved. Through this lens we will then consider how, historically,
these concepts have impacted and are now manifested in the different
typologies of implementations and assessments in more current VE research
and practice, including the chapters in this book. We finish by presenting
some of the thornier challenges in assessing VE and examples of how these
are being addressed.
Virtual exchange: issues in assessment design
Authors: Czura Anna
Published: September 2022

Virtual Exchange (VE) is typically set up in an institutional context, which implies the need to verify student learning through assessment. The difficulties in designing and implementing assessment in VE arise principally from the complexity of VE itself, as well as from a combination of institutional and sociocultural factors. This chapter aims to discuss the main tenets that need to be considered when designing assessment in VE on tertiary level. In particular, the importance of defining the construct and selecting appropriate content in safeguarding the validity of assessment is highlighted. The chapter also discusses the interplay between the purposes and the consequences of assessment in VE, and the form of assessment. All of these features are interconnected and often need to compromise formative and summative functions in order to comply with the institutional requirements. Next, the constructive alignment between the course objective, learning tasks, and assessment is addressed. The chapter concludes with the discussion of the sociocultural factors that require particular consideration in pedagogical initiatives involving participants from two or more distinctive educational contexts.

The Covid-19 pandemic, which has been active in Indonesia since early March 2020, has become a serious threat to all groups, including pregnant women, who are at a high risk of contracting the COVID-19 virus, particularly to the fetus they are carrying. Pregnant women require continuous knowledge and information in order to avoid anxiety. The goal of this study was to see if there was a link between pregnant women's knowledge and availability of information and their level of anxiety when performing ANC (Antenatal care) examinations. Observational study using a cross-sectional approach. This study's population consisted of 169 pregnant women, with a sample of 61 pregnant women drawn using a simple random sampling method. The findings revealed that 82.0% of pregnant women aged 17-45 years old (Mean: 28.31 and SD: 5.9), did not work, 32.8% of pregnant women with good knowledge did not experience anxiety, and 31.1% of pregnant women did not experience anxiety. Knowledgeable pregnant women have mild anxiety, and 3.3% of knowledgeable pregnant women have moderate anxiety. The Spearmen Rank correlation test results revealed that there was no relationship between knowledge (p value = 0.641 r = 0.061) and information availability (p value = 0.582 r = -0.072) and the level of anxiety of pregnant women during ANC (Antenatal care) examinations at the Mendik Health Center. It is hoped that with good knowledge and sufficient information can filter the right information and recommended that pregnant women consult with health workers diligently in order to obtain knowledge and information about pregnancy services.

Lithium-ion batteries using zinc oxide (ZnO) as anode material had a high theoretical capacity of about 987 mAh/g. Unfortunately, ZnO capacity can drop below 200 mAh/g after only a few cycles. For that reason, graphite was added in this study due to its stable theoretical capacity of around 348-374 mAh/g to maintain the stability of lithium-ion battery capacity. Zinc oxide/graphite (ZnO/Graphite) was prepared using a solid-state method, in which ZnO and graphite were mortared until homogeneous with the mass ratio of (2:1), (1:1), and (1:2). The SEM images of all samples showed the agglomerate morphology between ZnO and graphite which affect the results of the battery performance test. The final result of the ZnO/Graphite anode can be considered a continuous anode material due to the stable cycle performance obtained in the range of 219.72–371.27 mAh/g with a decreased value of 40% after 55 cycles.
