Abstract
Positronium (Ps) is generated before electron–positron annihilation in positron emission tomography (PET). As the Ps lifetime reflects the surrounding electron density, we aimed at its use for an innovative PET imaging. Here, as our first step, we demonstrated two-dimensional Ps lifetime imaging of certified reference materials using a pair of time-of-flight PET detectors. The imaged and calculated Ps lifetimes were very close to those of the reference materials, but the error values were larger than those of the reference materials. The results suggested that the accuracy of PET imaging with the ortho-positronium lifetime could be verified by those materials.

Published: August 2022

<p> Non-Fungible Tokens (NFTs) do hold the promise of providing Web3 with the opportunity for self-sovereignty of users’ physical assets. In this paper, we propose a generic NFT architecture for Web3. The architecture supports the rapid development of the upper application environment and automated value mapping of the underlying physical asset environment. To connect these two environments, a generic connecter has been designed to provide flexible storage for mapping data management, and to support universal cross-chain transactions. With these features, the values of heterogeneous physical assets can coexist in a unified Web3 world, and rich value transfer services can be developed on demand. This paper discusses the background of the proposed architecture, the open problems and our initial solution, as well as our design principles and advantages, and finally validates this novel NFT architecture. </p>

Published: August 2022

<p>Long Range (LoRa) is one of the most promising and widespread chirp spread spectrum (CSS)-based physical (PHY) layer technique for low-power wide-area networks (LPWANs). Using different spreading factors, LoRa can attain different spectral/energy efficiencies, and can target multitude of Internet-of-Thing (IoT) applications. However, one of the limiting factors for LoRa is the low bit rate. Little to no effort has been made in order to improve the achievable rate of LoRa, until recently, when a number of CSS-based PHY layer LoRa alternative are proposed for LPWANs. In this survey, for the first time, we present a comprehensive waveform design of these CSS-based schemes that have been proposed between 2019 to 2022. In total, fifteen alternatives to LoRa are compared. Other survey articles related to LoRa mostly tackle different issues, such as LoRa networking, LoRa deployment in massive IoT networks, and LoRa architectures, etc. This survey, on the other hand, comprehensively elucidates the waveform design of LoRa alternatives. The CSS schemes studied in this survey are divided into single chirp, multiple chirp, and index modulation based on the multiplexing pattern of the chirps. Complete transceiver architecture of these CSS schemes is studied, and performance is evaluated in terms of energy efficiency (EE), spectral efficiency (SE), bit-error rate (BER) performance in additive white Gaussian noise, BER in the presence of phase and frequency offsets. It has been observed that the EE, SE and robustness against the offsets is primarily linked to transmit symbol frame structure. The public versions of the MATLAB codes for the CSS schemes studied in this survey shall be provided to promote reproducible research.</p>

Published: August 2022

<p>The COVID-19 crisis has attracted attention worldwide to the supply chain disruptions and resilience. Several supply chain risk management approaches have been revisited or reapplied such as collaborative resource sharing. This study aimed to investigate the current academic state of art and advances in using collaborative resources sharing as a reactive method to facilitate supply chain recovery in the presence of disruptive events. More specifically we considered the role of different collaborative resource sharing strategies that organizations can adopt to support supply chain functionalities during times of disruption. We conducted a systematic literature review (SLR) to analyze academic articles that were published online from 2000 to 2022. In order to analyze the literature, we adopted a combination of text-mining, automatic and manual categorization of selected articles, and exploratory analyses such as cluster analysis and relational indicators. We also consider the machine learning classification algorithm i.e. agglomerative hierarchical clustering for the categorization of clusters. The findings show that, for disruptive risks, collaborative sharing of labour and material resources are effective for the recovery of supply chains. More so, labour resources tend to contribute more to the recovery of supply chains. Whilst information resources and a mix of information and material resources are highly important in reducing the impact of COVID-19 disruptive supply chain risk. In conclusion, collaborating on the three resources, namely labour, material, and information resources can be an effective post-disruption recovery strategy for supply chains. </p>
A Constant Common Mode Voltage Single-Phase Five-Level Transformerless PV Inverter Considering the Effect of Switch Device Junction Capacitance
Authors: Muktevi Vital LN , Sonti Venu , Siwakoti Yam P. , Lee Sze Sing , jain sachin 
Published: August 2022

<p>Constant common mode voltage (CCMV) is critical in Solar Photovoltaic (SPV) systems. Maintaining CCMV further eliminates the transitions in the voltage across the parasitic capacitance of the PV panel, making it a low-frequency output voltage waveform. This further reduces the leakage and common mode current in the SPV systems. This paper presents a five-level switched capacitor PV inverter configuration that maintains the CCMV with low-frequency terminal voltage while considering the effect of switch device junction capacitance (SDJC). Thus, the proposed configuration eliminates the transitions in the common mode and terminal voltage due to the SDJC. The two switched capacitors employed in the proposed configuration are charged and discharged within each switching period, supporting the self-charge balance feature apart from low voltage and RMS current rating, reducing its size and value. Further, the proposed system effectively utilizes the PV source as switch capacitors, and the dc-bus buffer capacitor across the PV source comes in parallel in each switching period. The proposed configuration can also operate at lower modulation indices generating three levels with CCMV. A new mathematical analysis considering SDJC is given for the derivation of expression for terminal voltage and CMV, which is further verified using simulation and experimental results </p>
GridTool: An Open-Source Tool to Convert Grid Data

Published: August 2022

<p>This paper introduces the open-source GridTool software available at <a href="https://github.com/IEE-TUGraz/GridTool" target="_blank">GitHub</a>. It is an easy-to-use tool to convert and simplify electricity grid data from the OpenStreetMap-project for the use in energy simulation models. The main advantages of the newly developed tool are its flexibility, customizability and its heuristic approach for identifying grid nodes. Instead of the lengthy and predominantly manual process of converting and implementing electricity grid data from transmission and distribution system operators, the GridTool shortens that task to seconds. During this process the OpenStreetMap data gets reduced to the essential things that are needed in energy simulation models for load flow purposes, with optional plots that help to tweak the most important settings. To our knowledge there is no other open-source tool, that works out-of-the-box that does this task and is as easy-to-use, only needs one program to run (MATLAB) and uses a heuristic approach. </p>

Hacia la revalorización del espacio periurbano
Authors: Solano-Meneses Eska Elena 
Published: August 2022

El espacio periurbano es el espacio resultante de un proceso de urbanización dispersa, producto de la expansión de la ciudad asociado con terrenos de índole rural. La peri-urbanización enmarca una difusa transición entre el campo y la ciudad. El objetivo de este trabajo es la reconsideración de los estigmas negativos que acompañan el surgimiento, fomento y desarrollo de los espacios periurbanos, para trasladar su discurso hacia una nueva propuesta de gestión urbana, que permita resarcir los errores cometidos en los espacios urbanos. Este estudio parte del supuesto que es posible modificar los procesos de gestión en el espacio periurbano para propugnar, bajo un nuevo paradigma, un proceso urbano consciente y planeado que reconsidere y respete los valores de un espacio rural en aras de una mejor calidad de vida de sus habitantes. La metodología propuesta es la comparación entre los espacios rurales y urbanos, así como de las gestiones que delinean sus procesos urbanos, con consideraciones desde lo ambiental, lo económico, la inclusión y lo social. Los resultados dan cuenta de la transición de los procesos urbanos en los espacios urbanos consolidados y los espacios periurbanos, así como de las posibles ventajas de la revalorización del espacio periurbano. Las conclusiones permiten asumir, que frente al enfoque de degradación y menoscabo que ha primado sobre los espacios periurbanos, es posible interpelar esos paradigmas dominantes, para así abrir la posibilidad de revalorarlos, y ser conscientes de la oportunidad que nos ofrece para rediseñarlos.

Published: August 2022

La dinámica demográfica que enfrenta hoy en día nuestras ciudades demanda una organización y estructura urbana que responda a los nuevos requerimientos, esto es, que responda a las necesidades de un sector cada vez más visible como lo es la atención de la población adulta mayor. Cada vez este sector demográfico se amplía, es decir, existe un mayor número de población adulta mayor en nuestras ciudades, por ende, los requerimientos en cuanto a estructura y organización de las ciudades son más específicos, tal es el caso de una estructura urbana y distribución de equipamiento urbano especializado que permita su fácil acceso a este sector vulnerable de la población. En este trabajo se tiene como objetivo analizar si la actual estructura y equipamiento urbanos especializado en la ciudad de Toluca, Metepec y Lerma satisface las necesidades de accesibilidad de la población adulta mayor y si esto incide en la calidad de vida de este sector de población vulnerable a fin de que pueda ser replicado en otras ciudades con características similares. Para lograrlo se recurre a una caracterización urbana en torno a indicadores como estructura urbana, equipamiento urbano especializado, población adulta mayor, desplazamientos, motivo de traslado, interacción espacial, entre otros. Dicha caracterización parte de información estadística, documental, y de campo. Todo ello se constituye en el insumo y soporte de este trabajo.

Introduction: Cataract is the main cause of visual impairment and vision loss in the world, where 33% of the world's population has decreased vision due to cataracts. This study aims to explore the role of platelet-rich plasma (PRP) in inhibiting the pro-inflammatory cytokine interleukin-1ß, thereby triggering tissue repair in cataract cases in vivo study.
Methods: This study is an experimental study with a post-test-only approach with a control group design. A total of 30 rats (Rattus norvegicus) Wistar strain was included in this study (male, 150-200 g, 8-10 weeks). The rats were divided into 3 groups, P1 (the group that was not induced by cataract and not treated with platelet-rich plasma), P2 (the group that was induced by cataract and given 10 uL of intraocular saline injection), and P3 (the group that was induced by cataract and given an intraocular injection of platelet-rich plasma). Plasma 10 uL).
Results: The results showed that the P3 group that received platelet-rich plasma treatment showed a significant decrease in IL-1B levels when compared to the P2 group with cataract induced but without PRP administration (p<0.05).
Conclusion: Activated platelet-rich plasma has potential as a new therapeutic modality in cataract conditions through inhibition of chronic inflammatory response in vivo studies.

Sociocultural Features of Anthroponymic Nicknames as a Group of the Unofficial Proper Names in English Military Discours
Authors: Буркова Т.А. , Хушвахтов Б.С. 
Published: August 2022

В ономастиконе военных особая роль принадлежит официальным и неофициальным антропонимическим номинациям. Если употребление официальных имен регламентировано правилами военной сферы, то неофициальные имена – это продукт имятворчества коллектива. У первых наблюдается статусность, которая объясняется наличием четкой иерархической системы в военной сфере. При неофициальном именовании лица формулируется субъективная оценка, граничащая между военной и обиходно-разговорной сферами общения. Закрытость армии создает предпосылки для возникновения языка – военного жаргона, элементом которого являются антропонимические прозвища – разряды номинации лица в неофициальном общении. Цель исследования заключается в социокультурной систематизации онимов в поле милитарной лексики английского языка. Эмпирическим материалом для исследования послужили прозвища военных, отобранные из англо-русских словарей военного сленга, энциклопедий. В статье описаны существующие подходы к трактовке понятий «неофициальное имя», «прозвище» в отечественной и зарубежной ономастике. Выявлены национально-культурные особенности неофициального именника военных. Систематизированы тематические группы антропонимических прозвищ в английском военном дискурсе, среди которых выделяются группы, указывающие на национальность, страну, срок и время службы военнослужащего, звание, должность, функциональные обязанности, внешние характеристики, черты характера, поступки носителя онима.
The purpose of this research is to identify the motives for creating anthroponomical nicknames in the military sphere. In the onomasticon of the military a special role belongs to the official and unofficial anthroponyms. If the use of official names in military discourse is regulated by the rules of the military sphere, unofficial names including anthroponymic nicknames are the product of the collective's names creativity, which occurs for various reasons. The specificity of the anthroponymic nickname in military discourse is due to the peculiarities of the implementation of this phenomenon on the border of the military and everyday spheres of human communication, in the process of which the subjectively formulated assessment is objectified. The closed nature of the army determines its corporatism and creates prerequisites for the emergence and development of a special language – military jargon, an element of which are anthroponymic nicknames – classes of the nomination of a person in informal communication. The empirical material for the study was the nicknames of the militaryselected by partial sampling from the English-Russian dictionaries of military slang and encyclopedias. We have identified the following groups of military anthroponomical nicknames, indicating: the nationality, country, military uniforms and attributes, term and time of military service, rank, position, functional responsibilities, external characteristics and character traits, behavior of the military.
