The current study attempted, for the first time, to qualitatively and quantitatively determine the phytochemical components of Elatostema papillosum methanol extract and their biological activities. The present study represents an effort to correlate our previously reported biological activities with a computational study, including molecular docking, and ADME/T (absorption, distribution, metabolism, and excretion/toxicity) analyses, to identify the phytochemicals that are potentially responsible for the antioxidant, antidepressant, anxiolytic, analgesic, and anti-inflammatory activities of this plant. In the gas chromatography-mass spectroscopy analysis, a total of 24 compounds were identified, seven of which were documented as being bioactive based on their binding affinities. These seven were subjected to molecular docking studies that were correlated with the pharmacological outcomes. Additionally, the ADME/T properties of these compounds were evaluated to determine their drug-like properties and toxicity levels. The seven selected, isolated compounds displayed favorable binding affinities to potassium channels, human serotonin receptor, cyclooxygenase-1 (COX-1), COX-2, nuclear factor (NF)-κB, and human peroxiredoxin 5 receptor proteins. Phytol acetate, and terpene compounds identified in E. papillosum displayed strong predictive binding affinities towards the human serotonin receptor. Furthermore, 3-trifluoroacetoxypentadecane showed a significant binding affinity for the KcsA potassium channel. Eicosanal showed the highest predicted binding affinity towards the human peroxiredoxin 5 receptor. All of these findings support the observed in vivo antidepressant and anxiolytic effects and the in vitro antioxidant effects observed for this extract. The identified compounds from E. papillosum showed the lowest binding affinities towards COX-1, COX-2, and NF-κB receptors, which indicated the inconsequential impacts of this extract against the activities of these three proteins. Overall, E. papillosum appears to be bioactive and could represent a potential source for the development of alternative medicines; however, further analytical experiments remain necessary.
Enhanced Sensitivity of CO on Two-Dimensional, Strained, and Defective GaSe

Published: February 2021

The toxic gas carbon monoxide (CO) is fatal to human beings and it is hard to detect because of its colorless and odorless properties. Fortunately, the high surface-to-volume ratio of the gas makes two-dimensional (2D) materials good candidates for gas sensing. This article investigates CO sensing efficiency with a two-dimensional monolayer of gallium selenide (GaSe) via the vacancy defect and strain effect. According to the computational results, defective GaSe structures with a Se vacancy have a better performance in CO sensing than pristine ones. Moreover, the adsorption energy gradually increases with the scale of tensile strain in defective structures. The largest adsorption energy reached −1.5 eV and the largest charger transfer was about −0.77 e. Additionally, the CO gas molecule was deeply dragged into the GaSe surface. We conclude that the vacancy defect and strain effect transfer GaSe to a relatively unstable state and, therefore, enhance CO sensitivity. The adsorption rate can be controlled by adjusting the strain scale. This significant discovery makes the monolayer form of GaSe a promising candidate in CO sensing. Furthermore, it reveals the possibility of the application of CO adsorption, transportation, and releasement.
Utilizing Recyclable Task-Specific Ionic Liquid for Selective Leaching and Refining of Scandium from Bauxite Residue
Authors: Mikeli Eleni , Balomenos Efthimios , Panias Dimitrios
Published: February 2021

Ionic liquids (ILs) have attracted great interest in the field of extractive metallurgy mainly because they can be utilized in low temperature leaching processes where they exhibit selectivity and recyclability. A major drawback in mixed aqueous-IL systems, is IL dissolution in the aqueous phase, which leads to IL losses, increasing the overall processing cost. This study advances the method for recovering scandium (Sc) from bauxite residue (BR) using as leaching agent the IL betainium bistriflimide, [Hbet][Tf2N] mixed with water, which has been reported in previous publications. Ionic liquid leachate (IL-PLS) was prepared by leaching BR with a mixture of [Hbet][Tf2N]-H2O and subjected to different stripping experiments using hydrochloric acid. The advancement, presented in this work, is related with the optimization of the metal extraction (stripping) from the IL-PLS, where an aqueous solution with high Sc concentration and minimum metal impurities and minimum IL co-extraction is produced. It is further proven that the metal cation extraction is defined by the stoichiometry of the acidic solution and the dissolution (losses) of the IL in the aqueous phase can be minimized by adjusting the volume ratio and the acid concentration. A two-step stripping process described, achieves the selective increase of Sc concentration by 8 times in the aqueous solution, while maintaining cumulative IL losses to similar levels as the optimum 1 step non-Sc selective stripping process.
Proposal of Highly Efficient Quantum Well Microring Resonator-Loaded Optical Phase Modulator Integrated with Antenna-Coupled Electrodes for Radio-over-Fiber
Authors: Kamada Hiro , Arakawa Taro
Published: February 2021

Radio-over-fiber (RoF) technology for low-loss, high-speed millimeter-wave transmission using optical fibers has been attracting attention. We propose a highly efficient microring resonator (MRR)-loaded InGaAs/InAlAs multiple-quantum-well (MQW) phase modulator with an antenna coupled electrode (ACE) for 60 GHz RoF systems, and its modulation characteristics are theoretically discussed. This modulator is able to directly convert wireless millimeter-wave (MMW) signals into optical signals without an external power supply. The MRR used in the waveguide structure increases the optical phase change obtained by the unique quantum confinement Stark effect in the MQW through phase enhancement effects, while the ACE based on a coupled microstrip resonant electrode applies a strong standing wave electric field to the waveguide. The proposed modulator is expected to provide tens of times higher phase modulation efficiency than a conventional gap-embedded planar antenna-integrated modulator.

Authors: Sun Fu-Min , Chou Yu-Jou , Huang Qingrong , Hu Jing-Yu , Ting Yuwen
Published: February 2021

Pterostilbene, a dimethylether analog of resveratrol, has been found to have potent biological activity. However, the bioavailability of pterostilbene in the biological system is limited due to its poor solubility in an aqueous environment. A nanoemulsion system was designed for this purpose. Lecithin-based nanoemulsion was formed after 3 cycles through a high-pressure homogenizer at 500 psi. The rheological properties and particle size were measured using dynamic light scattering and a viscometer. The storage stabilities of the prepared formulation were determined based on its ability to maintain its particle size and loading concentration. According to the experimental results, the lecithin-based nanoemulsion system contained approximately 9.5% of pterostilbene. Over the 28-day stability test, the particle size, zeta potential, and encapsulation of pterostilbene in the nanoemulsion did not change significantly, indicating good storage stability. The positive effect of the prepared nanoemulsion system on bioavailability was studied and confirmed using in vitro lipolysis and a caco-2 monolayer model.
Efficient Anomaly Detection for Smart Hospital IoT Systems
Authors: Said Abdel Mlak , Yahyaoui Aymen , Abdellatif Takoua
Published: February 2021

In critical Internet of Things (IoT) application domains, such as the Defense Industry and Healthcare, false alerts have many negative effects, such as fear, disruption of emergency services, and waste of resources. Therefore, an alert must only be sent if triggered by a correct event. Nevertheless, IoT networks are exposed to intrusions, which affects event detection accuracy. In this paper, an Anomaly Detection System (ADS) is proposed in a smart hospital IoT system for detecting events of interest about patients’ health and environment and, at the same time, for network intrusions. Providing a single system for network infrastructure supervision and e-health monitoring has been shown to optimize resources and enforce the system reliability. Consequently, decisions regarding patients’ care and their environments’ adaptation are more accurate. The low latency is ensured, thanks to a deployment on the edge to allow for a processing close to data sources. The proposed ADS is implemented and evaluated while using Contiki Cooja simulator and the e-health event detection is based on a realistic data-set analysis. The results show a high detection accuracy for both e-health related events and IoT network intrusions.
Human and Human-Interfaced AI Interactions: Modulation of Human Male Autonomic Nervous System via Pupil Mimicry
Authors: Spicer Catherine , Khwaounjoo Prashanna , Cakmak Yusuf Ozgur
Published: February 2021

Pupillary alterations in virtual humans induce neurophysiological responses within an observer. Technological advances have enabled rapid developments in artificial intelligence (AI), from verbal systems, to visual AI interfaces with the ability to express, and respond to emotional states of a user. Visual AI interfaces are able to change their physical parameters, such as pupil diameter. Pupillary changes can alter heart rate, however, effects on heart rate variability (HRV) are unknown. HRV, is an autonomic, non-conscious parameter which monitors sympathetic and parasympathetic nervous system (PNS) activity. N = 34 male participants aged between 19–33 were subjected to a number of conditions such as pupil dilation, constriction and blushing. The present research is the first to investigate the effects of virtual human interactions on human HRV. Outcomes of this study were obtained using eye tracking and HRV measurements. Pupil dilation relative to constriction presented in the female virtual partner induced a significant right pupillary diameter increase (p = 0.041) in human observers. Additionally, female virtual partner pupil constriction relative to dilation induced a significant increase in participants’ PNS HRV response (p = 0.036). These findings indicate the ability of a female virtual interaction partner to modulate parasympathetic autonomic functioning in young healthy male humans. This allows first insights into the effects of interacting with virtual AI interaction partners, on human autonomic functioning, and may aid development of future virtual humans, and their implementation into relevant clinical settings.

Authors: Chen Jerry , Abbod Maysam , Shieh Jiann-Shing
Published: February 2021

Pain is a subjective feeling; it is a sensation that every human being must have experienced all their life. Yet, its mechanism and the way to immune to it is still a question to be answered. This review presents the mechanism and correlation of pain and stress, their assessment and detection approach with medical devices and wearable sensors. Various physiological signals (i.e., heart activity, brain activity, muscle activity, electrodermal activity, respiratory, blood volume pulse, skin temperature) and behavioral signals are organized for wearables sensors detection. By reviewing the wearable sensors used in the healthcare domain, we hope to find a way for wearable healthcare-monitoring system to be applied on pain and stress detection. Since pain leads to multiple consequences or symptoms such as muscle tension and depression that are stress related, there is a chance to find a new approach for chronic pain detection using daily life sensors or devices. Then by integrating modern computing techniques, there is a chance to handle pain and stress management issue.
Intelligent Video Highlights Generation with Front-Camera Emotion Sensing
Authors: Meyer Hugo , Wei Peter , Jiang Xiaofan
Published: February 2021

In this paper, we present HOMER, a cloud-based system for video highlight generation which enables the automated, relevant, and flexible segmentation of videos. Our system outperforms state-of-the-art solutions by fusing internal video content-based features with the user’s emotion data. While current research mainly focuses on creating video summaries without the use of affective data, our solution achieves the subjective task of detecting highlights by leveraging human emotions. In two separate experiments, including videos filmed with a dual camera setup, and home videos randomly picked from Microsoft’s Video Titles in the Wild (VTW) dataset, HOMER demonstrates an improvement of up to 38% in F1-score from baseline, while not requiring any external hardware. We demonstrated both the portability and scalability of HOMER through the implementation of two smartphone applications.
Multi-Camera Based Setup for Geometrical Measurement of Free-Falling Molten Glass Gob
Authors: Hussain Mazhar , O’Nils Mattias , Lundgren Jan
Published: February 2021

High temperatures complicate the direct measurements needed for continuous characterization of the properties of molten materials such as glass. However, the assumption that geometrical changes when the molten material is in free-fall can be correlated with material characteristics such as viscosity opens the door to a highly accurate contactless method characterizing small dynamic changes. This paper proposes multi-camera setup to achieve accuracy close to the segmentation error associated with the resolution of the images. The experimental setup presented shows that the geometrical parameters can be characterized dynamically through the whole free-fall process at a frame rate of 600 frames per second. The results achieved show the proposed multi-camera setup is suitable for estimating the length of free-falling molten objects.

Published: February 2021

The operation and maintenance of buildings has seen several advances in recent years. Multiple information and communication technology (ICT) solutions have been introduced to better manage building maintenance. However, maintenance practices in buildings remain less efficient and lead to significant energy waste. In this paper, a predictive maintenance framework based on machine learning techniques is proposed. This framework aims to provide guidelines to implement predictive maintenance for building installations. The framework is organised into five steps: data collection, data processing, model development, fault notification and model improvement. A sport facility was selected as a case study in this work to demonstrate the framework. Data were collected from different heating ventilation and air conditioning (HVAC) installations using Internet of Things (IoT) devices and a building automation system (BAS). Then, a deep learning model was used to predict failures. The case study showed the potential of this framework to predict failures. However, multiple obstacles and barriers were observed related to data availability and feedback collection. The overall results of this paper can help to provide guidelines for scientists and practitioners to implement predictive maintenance approaches in buildings.

Published: February 2021

Wearable technology will become available and allow prolonged electroencephalography (EEG) monitoring in the home environment of patients with epilepsy. Neurologists analyse the EEG visually and annotate all seizures, which patients often under-report. Visual analysis of a 24-h EEG recording typically takes one to two hours. Reliable automated seizure detection algorithms will be crucial to reduce this analysis. We investigated such algorithms on a dataset of behind-the-ear EEG measurements. Our first aim was to develop a methodology where part of the data is deferred to a human expert, who performs perfectly, with the goal of obtaining an (almost) perfect detection sensitivity (DS). Prediction confidences are determined by temperature scaling of the classification model outputs and trust scores. A DS of approximately 90% (99%) can be achieved when deferring around 10% (40%) of the data. Perfect DS can be achieved when deferring 50% of the data. Our second contribution demonstrates that a common modelling strategy, where predictions from several short EEG segments are combined to obtain a final prediction, can be improved by filtering out untrustworthy segments with low trust scores. The false detection rate shows a relative decrease between 21% and 43%, and the DS shows a small increase or decrease.
Benefit of New High-Precision LLR Data for the Determination of Relativistic Parameters
Authors: Biskupek Liliane , Müller Jürgen , Torre Jean-Marie
Published: February 2021

Since 1969, Lunar Laser Ranging (LLR) data have been collected by various observatories and analysed by different analysis groups. In the recent years, observations with bigger telescopes (APOLLO) and at infra-red wavelength (OCA) are carried out, resulting in a better distribution of precise LLR data over the lunar orbit and the observed retro-reflectors on the Moon. This is a great advantage for various investigations in the LLR analysis. The aim of this study is to evaluate the benefit of the new LLR data for the determination of relativistic parameters. Here, we show current results for relativistic parameters like a possible temporal variation of the gravitational constant G˙/G0=(−5.0±9.6)×10−15yr−1, the equivalence principle with Δmg/miEM=(−2.1±2.4)×10−14, and the PPN parameters β−1=(6.2±7.2)×10−5 and γ−1=(1.7±1.6)×10−4. The results show a significant improvement in the accuracy of the various parameters, mainly due to better coverage of the lunar orbit, better distribution of measurements over the lunar retro-reflectors, and last but not least, higher accuracy of the data. Within the estimated accuracies, no violation of Einstein’s theory is found and the results set improved limits for the different effects.

Los sistemas de diagnóstico automatizados para la detección de soplos cardiacos, descritos en la literatura, regis-tran en intervalos cortos de tiempo la dinámica fisiológica a partir de bases de datos de señales fonocardiográficas segmentadas, obteniendo una multiplicidad de muestras del mismo paciente sin tener en cuenta la dinámica car-diaca de cada individuo, lo cual no garantiza una adecuada identificación de la anomalía cardiaca. El sistema de asistencia de diagnóstico propuesto inicia con el estudio de 1060 señales tomadas de los cuatro focos de auscul-tación cardiaca de 144 pacientes, agrupados principalmente en dos clases: normales y patológicos. Los registros se agruparon por su posición en el periodo cardiaco en 4 tipos: normales, soplo sistólico, diastólico y sistodias-tólico, obteniendo una base de datos de señales fonocardiográficas, a la cual se le realiza un preprocesamiento, sin embargo, no se segmenta para conservar la dinámica cardiaca de cada individuo en el estudio. Luego se genera un espacio de representación a partir de los PLP y los coeficientes cepstrales calculados a partir de la FFT y la STFT, desarrollando un análisis con los clasificadores estocásticos HMM y GMM y técnicas de selección de caracterís-ticas para la extracción de información relevante de la dinámica fisiológica, que permitan un adecuado y eficiente entrenamiento del sistema con una tasa adecuada de clasificación para soporte de diagnóstico clínico.

Published: February 2021

En este artículo se muestra como las restricciones debidas a saturaciones conducen a respuestas inesperadas en sistemas lineales. Se emplea un modelo basado en máquinas de estado finito para la simulación de un sis-tema de primer orden con un controlador proporcional-integral (PI) con saturaciones en la acción de control integral y en el actuador. Las simulaciones permiten observar como dichas saturaciones pueden determinar la existencia de seis diferentes configuraciones para el sistema. Resultados numéricos permiten confirmar que la contribución de cada configuración conduce la dinámica del sistema a una órbita periódica aislada. Este comportamiento es validado con resultados experimentales de un servocontrolador PI para un motor DC con anti-windup en la acción de control integral.

Published: February 2021

The tides, which affect the water level of the Musi River causes some problems to occur in Palembang City. One of the main problems related to the tides of the Musi River, especially the low tide, is the failure of the raw water intake building of Regional Drinking Water Company  (PDAM) Tirta Musi, Palembang City to operate. At a certain time the river water level recedes, the minimum water level entering the intake pump room is lower than the safe level for the pump to run. In this study, an analysis of the tides of the Musi River was carried out using the Least Square method to evaluate the design of the raw water intake building for the Gandus system to disclose whether it meets the minimum elevation requirements for pump operation. The field observations of the tides were carried out for 15 days for every 1 hour to obtain the primary data for this study using the Hobo Water Meter. The results of this study indicate that the type of the tides in the location of the study is a mixed tidal type with a Formzahl Value of 2.01. 4. Against the design plan of the gandus system of raw water intake, there is a chance that the elevation of the river water level is at 0.5 m from the end of the pump suction pipe, in which the pump cannot function.
A legal paradigm shift towards climate justice in the Anthropocene
Authors: Adelman Sam
Published: February 2021

Business as usual is widely acknowledged as the main driver of ecological collapse and climate breakdown, but less attention is paid to the role of law as usual as an impediment to climate justice. This article analyses how domestic and international environmental law facilitate injustices against living entities and nature. It calls for a paradigm shift in legal theory, practice and teaching to reflect the scale and urgency of the unfolding ecological catastrophe. Section 2 outlines the links between climatic harms and climate injustices. This is followed by discussions of unsustainable law and economic development in sections 3 and 4. Section 5 examines the potential contribution of new materialist legal theory in bringing about a legal paradigm shift that reflects the jurisgenerative role of nature in promoting climate justice.

Published: February 2021

Evaluating the socio-technical dialectic reveals much about our values as a society, as a construction industry and as individual disciplines. This paper will share an interpretive cultural history of building in order to establish a context for the emergence of integrated practice technologies such as BIM, IPD and LEED. This will provide the foundation for determining whether these technologies are serving us well in contemporary practice given our most pressing challenges and opportunities. In short the purpose of this paper is to explain the context of building as a means for making our current practices more performative, that is less abstract and autonomous, and instead more connected, meaningful and valuable to the future of both society and the building industry.

Published: February 2021

Статья посвящена дискуссионному в историографии вопросу о численности крымских татар в первой трети ХХ века. Данные различных подсчетов их количества существенным образом расходятся. Из приведенных фактов следует, что использование статистики в политических целях стала характерной чертой советской национальной политики рассматриваемого периода, а некритическое использование подобных официальных данных современными историками уводит все дальше от реального исторического процесса, который происходил тогда в Крыму.

The article examines a highly debatable question in historiography that is the population of Crimean Tatars during the first third of the 20th C. The available data from different sources differs greatly.
Presented are the facts which show how the usage of statistics turned to be a characteristic feature of Soviet national policy. Official data can thus lead away from the real picture without a critical analysis of the processes which took place in the Crimea at that time.
Predecessors & consequences of a tragedy: May 28 – June 01, 1945 Drau massacre
Authors: Кумук Дж.
Published: February 2021

В статье рассматривается национальное и общественно-политическое противостояние северокавказских горцев большевистскому нашествию, проявившееся в антисоветской борьбе горской интеллигенции в европейских столицах в межвоенный период, массовом убийстве тысяч ни в чем не повинных людей в долине Драу в 1945 году, трагической истории жизни одного из беженцев по имени Черим Сообцоков, пережившего мировую войну, а также в экстрадиции и казнях сталинского режима. В конце концов, мы зададим себе простой вопрос: кто из них был худшим из зол? Иосиф Сталин или Адольф Гитлер? И при каких условиях их жертвы могут считаться преступниками только потому, что они надеялись на помощь одного из них, чтобы избежать угрозы, исходящей от другого?

The article examines the related national and socio-political resistance of the North Caucasian highlanders against the Bolshevik invasion embodied with the experiences of the anti-Soviet struggle of Mountain intelligentsia in European capitals during the interwar period, the massacre of thousands of innocent people in the Drau valley in 1945, and the tragic life story of an individual refugee named Tscherim Soobzokov, who survived the world war and the extradition to Stalinist execution. In the end, we ask a simple question to ourselves; Which one was more evil? Joseph Stalin or Adolf Hitler? And, in what circumstances should their victims can be considered as criminals just because they believed help from either of them to avoid the danger caused by the other?

Конференция, организованная Министерством иностранных дел Германии в 1942 году для многочисленной группы кавказских политиков-эмигрантов, известная как «Адлониада» (была названа в честь берлинской гостиницы, в которой останавливалось большинство участников), оказалась ключевым событием в формировании немецкой политики по отношению к Кавказскому региону. Пять опубликованных здесь писем впервые дают представление о работе конференции с точки зрения трех участников с Северного Кавказа и из Азербайджана. Эти письма помогают нам глубже понять ход определенных событий, погрузиться в интриги и политические инициативы участвующих в них кавказских эмигрантов, а также определить их отношение к немецкой принимающей стороне.

A conference organised by the German Foreign Ministry in 1942 for a large group of émigré politicians from the Caucasus – commonly referred to as the ‘Adloniada’ after the Berlin hotel most of them were staying at – proved to be a pivotal event in the evolution of German policies regarding the Caucasus region. Five letters published here for the first time provide an insight into its proceedings from the perspective of three participants from the North Caucasus and Azerbaijan. They help further our understanding of the concrete course of events, the intrigues among and political proposals of the attending Caucasian émigrés, as well as their attitudes towards their German hosts.
