Published: September 2020

Although vegetation phenology thresholds have been developed for a wide range of mapping applications, their use for assessing the distribution of natural bamboo and the related carbon stocks is still limited, especially in Southeast Asia. Here, we used Google Earth Engine (GEE) to collect time-series of Landsat 8 Operational Land Imager (OLI) and Sentinel-2 images and employed a phenology-based threshold classification method (PBTC) to map the natural bamboo distribution and estimate carbon stocks in Siem Reap Province, Cambodia. We processed 337 collections of Landsat 8 OLI for phenological assessment and generated 121 phenological profiles of the average vegetation index for three vegetation land cover categories from 2015 to 2018. After determining the minimum and maximum threshold values for bamboo during the leaf-shedding phenology stage, the PBTC method was applied to produce a seasonal composite enhanced vegetation index (EVI) for Landsat collections and assess the bamboo distributions in 2015 and 2018. Bamboo distributions in 2019 were then mapped by applying the EVI phenological threshold values for 10 m resolution Sentinel-2 satellite imagery by accessing 442 tiles. The overall Landsat 8 OLI bamboo maps for 2015 and 2018 had user’s accuracies (UAs) of 86.6% and 87.9% and producer’s accuracies (PAs) of 95.7% and 97.8%, respectively, and a UA of 86.5% and PA of 91.7% were obtained from Sentinel-2 imagery for 2019. Accordingly, carbon stocks of natural bamboo by district in Siem Reap at the province level were estimated. Emission reductions from the protection of natural bamboo can be used to offset 6% of the carbon emissions from tourists who visit this tourism-destination province. It is concluded that a combination of GEE and PBTC and the increasing availability of remote sensing data make it possible to map the natural distribution of bamboo and carbon stocks.
Global Cyclone and Anticyclone Detection Model Based on Remotely Sensed Wind Field and Deep Learning
Authors: Xie Ming , Li Ying , Cao Kai
Published: September 2020

Cyclone detection is a classical topic and researchers have developed various methods of cyclone detection based on sea-level pressure, cloud image, wind field, etc. In this article, a deep-learning algorithm is incorporated with modern remote-sensing technology and forms a global-scale cyclone/anticyclone detection model. Instead of using optical images, wind field data obtained from Mean Wind Field-Advanced Scatterometer (MWF-ASCAT) is utilized as the dataset for model training and testing. The wind field vectors are reconstructed and fed to the deep-learning model, which is built based on a faster-region with convolutional neural network (faster-RCNN). The model consists of three modules: a series of convolutional and pooling layers as the feature extractor, a region proposal network that searches for the potential areas of cyclone/anticyclone within the dataset, and the classifier that classifies the proposed region as cyclone or anticyclone through a fully-connected neural network. Compared with existing methods of cyclone detection, the test results indicate that this model based on deep learning is able to reduce the number of false alarms, and at the same time, maintain high accuracy in cyclone detection. An application of this method is presented in the article. By processing temporally continuous data of wind field, the model is able to track the path of Hurricane Irma in September, 2017. The advantages and limitations of the model are also discussed in the article.

Published: September 2020

Over the past decade Unmanned Aircraft Systems (UAS, aka “drones”) have become pervasive, touching virtually all aspects of our world. While UAS offer great opportunity to better our lives and strengthen economies, at the same time these can significantly disrupt manned flight operations and put our very lives in peril. Balancing the demanding and competing requirements of safely integrating UAS into the United States (US) National Airspace System (NAS) has been a top priority of the Federal Aviation Administration (FAA) for several years. This paper outlines efforts taken by the FAA and the National Aeronautics and Space Administration (NASA) to create the UAS Traffic Management (UTM) system as a means to address this capability gap. It highlights the perspectives and experiences gained by the University of Alaska Fairbanks (UAF) Alaska Center for Unmanned Aircraft Systems Integration (ACUASI) as one of the FAA’s six UAS test sites participating in the NASA-led UTM program. The paper summarizes UAF’s participation in the UTM Technical Capability Level (TCL1-3) campaigns, including flight results, technical capabilities achieved, lessons learned, and continuing challenges regarding the implementation of UTM in the NAS. It also details future efforts needed to enable practical Beyond-Visual-Line-of-Sight (BVLOS) flights for UAS operations in rural Alaska.

Assessment of Leaf Area Index Models Using Harmonized Landsat and Sentinel-2 Surface Reflectance Data over a Semi-Arid Irrigated Landscape
Authors: Mourad Roya , Jaafar Hadi , Anderson Martha , Gao Feng
Published: September 2020

Leaf area index (LAI) is an essential indicator of crop development and growth. For many agricultural applications, satellite-based LAI estimates at the farm-level often require near-daily imagery at medium to high spatial resolution. The combination of data from different ongoing satellite missions, Sentinel 2 (ESA) and Landsat 8 (NASA), provides this opportunity. In this study, we evaluated the leaf area index generated from three methods, namely, existing vegetation index (VI) relationships applied to Harmonized Landsat-8 and Sentinel-2 (HLS) surface reflectance produced by NASA, the SNAP biophysical model, and the THEIA L2A surface reflectance products from Sentinel-2. The intercomparison was conducted over the agricultural scheme in Bekaa (Lebanon) using a large set of in-field LAIs and other biophysical measurements collected in a wide variety of canopy structures during the 2018 and 2019 growing seasons. The major studied crops include herbs (e.g., cannabis: Cannabis sativa, mint: Mentha, and others), potato (Solanum tuberosum), and vegetables (e.g., bean: Phaseolus vulgaris, cabbage: Brassica oleracea, carrot: Daucus carota subsp. sativus, and others). Additionally, crop-specific height and above-ground biomass relationships with LAIs were investigated. Results show that of the empirical VI relationships tested, the EVI2-based HLS models statistically performed the best, specifically, the LAI models originally developed for wheat (RMSE:1.27), maize (RMSE:1.34), and row crops (RMSE:1.38). LAI derived through European Space Agency’s (ESA) Sentinel Application Platform (SNAP) biophysical processor underestimated LAI and provided less accurate estimates (RMSE of 1.72). Additionally, the S2 SeLI LAI algorithm (from SNAP biophysical processor) produced an acceptable accuracy level compared to HLS-EVI2 models (RMSE of 1.38) but with significant underestimation at high LAI values. Our findings show that the LAI-VI relationship, in general, is crop-specific with both linear and non-linear regression forms. Among the examined indices, EVI2 outperformed other vegetation indices when all crops were combined, and therefore it can be identified as an index that is best suited for a unified algorithm for crops in semi-arid irrigated regions with heterogeneous landscapes. Furthermore, our analysis shows that the observed height-LAI relationship is crop-specific and essentially linear with an R2 value of 0.82 for potato, 0.79 for wheat, and 0.50 for both cannabis and tobacco. The ability of the linear regression to estimate the fresh and dry above-ground biomass of potato from both observed height and LAI was reasonable, yielding R2: ~0.60.

Published: September 2020

We analyzed the distribution of suspended sediments concentration (SSC) in the Yellow River Estuary based on data from GaoFen-1 (GF-1), which is a high-resolution satellite carrying a wide field-of-view (WFV) sensor and panchromatic and a multispectral (PMS) sensor on it. A new SSC retrieval model for the wide field-of-view sensor (M-WFV) was established based on the relationship between in-situ SSC and the reflectance in blue and near infrared bands. SSC obtained from 16 WFV1 images were analyzed in the Yellow River Estuary. The results show that (1) SSC in the study area is mainly 100–3500 mg/L, with the highest value being around 4500 mg/L. (2) The details of suspended sediment injection phenomenon were found in the Yellow River Estuary. The SSC distribution in the coastal water has two forms. One is that the high SSC water evenly distributes near the coast and the gradient of the SSC is similar. The other is that the high SSC water concentrates at the right side of the estuary (Laizhou Bay) with a significantly large area. Usually, there is a clear-water notch at the left side of the estuary. (3) Currents clearly influenced the SSC distribution in the Yellow River Estuary. The SSC gradient in the estuary was high against the local current direction. On the contrary, the SSC gradient in the estuary was small towards the local current direction. Eroding the coast and resuspension of the bottom sediments, together with currents, are the major factors influencing the SSC distribution in nearshore water in the Yellow River Estuary.

Under the impact of natural and anthropogenic climate variability, upwelling systems are known to change their properties leading to associated regime shifts in marine ecosystems. These often impact commercial fisheries and societies dependent on them. In a region where in situ hydrographic and biological marine data are scarce, this study uses a combination of remote sensing and ocean modelling to show how a stable seasonal upwelling off the Kenyan coast shifted into the territorial waters of neighboring Tanzania under the influence of the unique 1997/98 El Niño and positive Indian Ocean Dipole event. The formation of an anticyclonic gyre adjacent to the Kenyan/Tanzanian coast led to a reorganization of the surface currents and caused the southward migration of the Somali–Zanzibar confluence zone and is attributed to anomalous wind stress curl over the central Indian Ocean. This caused the lowest observed chlorophyll-a over the North Kenya banks (Kenya), while it reached its historical maximum off Dar Es Salaam (Tanzanian waters). We demonstrate that this situation is specific to the 1997/98 El Niño when compared with other the super El-Niño events of 1972,73, 1982–83 and 2015–16. Despite the lack of available fishery data in the region, the local ecosystem changes that the shift of this upwelling may have caused are discussed based on the literature. The likely negative impacts on local fish stocks in Kenya, affecting fishers’ livelihoods and food security, and the temporary increase in pelagic fishery species’ productivity in Tanzania are highlighted. Finally, we discuss how satellite observations may assist fisheries management bodies to anticipate low productivity periods, and mitigate their potentially negative economic impacts.

Published: September 2020

Self-driving cars and autonomous vehicles are revolutionizing the automotive sector, shaping the future of mobility altogether. Although the integration of novel technologies such as Artificial Intelligence (AI) and Cloud/Edge computing provides golden opportunities to improve autonomous driving applications, there is the need to modernize accordingly the whole prototyping and deployment cycle of AI components. This paper proposes a novel framework for developing so-called AI Inference Engines for autonomous driving applications based on deep learning modules, where training tasks are deployed elastically over both Cloud and Edge resources, with the purpose of reducing the required network bandwidth, as well as mitigating privacy issues. Based on our proposed data driven V-Model, we introduce a simple yet elegant solution for the AI components development cycle, where prototyping takes place in the cloud according to the Software-in-the-Loop (SiL) paradigm, while deployment and evaluation on the target ECUs (Electronic Control Units) is performed as Hardware-in-the-Loop (HiL) testing. The effectiveness of the proposed framework is demonstrated using two real-world use-cases of AI inference engines for autonomous vehicles, that is environment perception and most probable path prediction.
Standing Wave Binding of Hemispherical Resonator Containing First–Third Harmonics of Mass Imperfection under Linear Vibration Excitation
Authors: Huo Yan , Ren Shunqing , Wei Zhennan , Yi Guoxing
Published: September 2020

Due to complicated processing technology, the mass distribution of a hemispherical resonator made of fused silica is not uniform, which can affect the azimuth of the standing wave of a resonator under the linear vibration excitation. Therefore, the analysis of standing wave evolution of a resonator with mass imperfection under linear vibration excitation is of significance for the improvement of the output accuracy of a gyroscope. In this paper, it is assumed that the resonator containing the first–third harmonics of mass imperfection is excited by horizontal and vertical linear vibration, respectively; then, the equations of motion of an imperfect resonator under the second-order vibration mode are established by the elastic thin shell theory and Lagrange mechanics principle. Through error mechanism analysis, it is found that, when the frequency of linear vibration is equal to the natural frequency of resonator, the standing wave is bound in the azimuth of different harmonics of mass imperfection with the change in vibration excitation direction. In other words, there are parasitic components in the azimuth of the standing wave of a resonator under linear vibration excitation, which can cause distortion of the output signal of a gyroscope. On the other hand, according to the standing wave binding phenomenon, the azimuths of the first–third harmonics of mass imperfection of a resonator can also be identified under linear vibration excitation, which can provide a theoretical method for the mass balance of an imperfect resonator.

Drugs are the most widely used therapeutic tool for treatment of diseases. However, misuse can lead to an adverse drug event (ADE) in susceptible individuals such as those that are severely obese. This study aimed to describe the frequency of ADEs, the associations of ADEs with anatomical therapeutic chemical classes and their respective frequency, estimate the prevalence of ADEs, and analyse factors associated with ADE in adults with severe obesity. Cross-sectional analysis of baseline data from a randomized clinical trial in the central-western region of Brazil. A total of 150 individuals aged 18–65 years with a Body Mass Index of 35 kg/m2 were included. The outcome variable was the presence of ADE and the explanatory variables were socio-demographic factors, lifestyle, health, and medication use. ADEs were associated with use of drugs for the digestive tract and metabolism (p < 0.001) and the cardiovascular system (p < 0.001). The prevalence of ADEs was 32.67% (n = 49) and associated with the age range 40 to 49 years (p = 0.033), diabetes (p = 0.004), multimorbidities ≥ 4 (p = 0.009), self-medication (0.031), and presence of potential drug interactions (0.017). The prevalence of ADEs was high and was associated with drugs commonly used in treatment of obesity-related morbidities and self-medication. The introduction of a pharmacist to multi-professional teams can improve medication safety for severely obese patients.
Democracy, Biodiversity and More than Human Justice Imperatives: Institutional Responses to Crisis
Authors: Skillington Tracey
Published: September 2020

In terms of a human responsibility for the wrongful expulsion of non-human nature from natural habitats through wildfires, global warming, the over-exploitation of lands, seas and biological life, humanity is forced to revisit some fundamental issues of late with regard to the ongoing legitimacy of its claims to the Earth’s resources. Can human communities continue to lay claim to remaining essential reserves with little regard for the life situation of non-human others? Should certain principles of distributive and territorial justice, claims of occupancy, freedom of movement, respect, etc., be extended to include non-human nature? In recent months, Europe has begun to explore many of these concerns, noting the trauma experiences of COVID-19 and their interconnection with deepening ecological and health problems as a stimulus to action. This paper notes the relevance of these crisis experiences in moving political debate on the loss of biological diversity forward, prompting a need to extend normative horizons of the common good to include more biologically diverse communities.
An Unconventional Flavivirus and Other RNA Viruses in the Sea Cucumber (Holothuroidea; Echinodermata) Virome
Authors: Hewson Ian , Johnson Mitchell R. , Tibbetts Ian R.
Published: September 2020

Sea cucumbers (Holothuroidea; Echinodermata) are ecologically significant constituents of benthic marine habitats. We surveilled RNA viruses inhabiting eight species (representing four families) of holothurian collected from four geographically distinct locations by viral metagenomics, including a single specimen of Apostichopus californicus affected by a hitherto undocumented wasting disease. The RNA virome comprised genome fragments of both single-stranded positive sense and double stranded RNA viruses, including those assigned to the Picornavirales, Ghabrivirales, and Amarillovirales. We discovered an unconventional flavivirus genome fragment which was most similar to a shark virus. Ghabivirales-like genome fragments were most similar to fungal totiviruses in both genome architecture and homology and had likely infected mycobiome constituents. Picornavirales, which are commonly retrieved in host-associated viral metagenomes, were similar to invertebrate transcriptome-derived picorna-like viruses. The greatest number of viral genome fragments was recovered from the wasting A. californicus library compared to the asymptomatic A. californicus library. However, reads from the asymptomatic library recruited to nearly all recovered wasting genome fragments, suggesting that they were present but not well represented in the grossly normal specimen. These results expand the known host range of flaviviruses and suggest that fungi and their viruses may play a role in holothurian ecology.
The Unique Study of Talent Cultivation for English Major in Private Universities of China
Authors: Jia Weizhang , Zhang Shufang
Published: September 2020

The paper focused on the research of talent cultivation for English major in the universities of China, especially in private universities. It is often criticized that the English major makes no difference from public English or English training. The main problems of English major at present in China Universities are in its personnel cultivating program, and course design. These problems are shown in the paper mainly by case studies, literature research from the authors’ teaching experience. To solve these problems, the traditional English major must make some tentative innovation and improvement. For the personnel cultivating, it must make a balance between specialists and generalists. For the major setup, it should make refinement in different fields and aspects to let the students make a choice according to their own interests and characteristics, so the paper proposed the mechanism of general enrollment and stratified cultivating. For the course design, it is necessary to make a change from “learning English” to “learning in English”. Learning English mainly lies with students. The learning process, especially the skill-based learning, mainly lies in the learners themselves, while the task of the teacher plays the role of mentor and supervisor. Learning in English is the main direction of English teachers’ efforts. It is the main mission of the teachers of English major to teach humanities courses in full English, cultivate students’ critical thinking in teaching, and let students actively participate in classroom interaction. With these changes, the English major can strive to achieve its own development by being unique and new.

The fight against corruption in Ukraine is one of the main tasks of law enforcement agencies. However, the process of proving corruption crimes in criminal cases is accompanied by problems that negatively affect the quality of the pre-trial investigation. The purpose of the article is to identify and study typical investigative errors and develop recommendations on the proper use of means and methods of proof in criminal cases of corruption crimes, taking into account the norms of national legislation and international criteria for ensuring human rights in criminal proceedings. To achieve this goal, a comparative and systemic structural analysis of international and domestic regulatory legal acts and court decisions, a selective study of materials from criminal cases on corruption crimes were made. It has been established that the process of proving in cases of corruption crimes in Ukraine will fully comply with international standards for ensuring human rights, provided that operational officers, investigators, and prosecutors comply with the admissibility criterion of evidence, especially when using secret measures. Investigative errors that take place at the stage of pre-trial investigation in this category of criminal cases lead to the restriction of human rights and freedoms and consist in significant violations of the criminal procedural law when collecting, checking, and evaluating evidence, as well as when opening the collected materials to the defense. Preventing such violations requires strict adherence to the general requirements for conducting undercover activities, formulated in the decisions of the European Court of Human Rights and domestic courts. The proof must take into account the "fruit of the poisonous tree" doctrine of the inadmissibility of evidence derived from materials collected in violation of the law. The defense side should be provided with timely access to the materials of covert events, including the documents that served as the basis for their implementation. It is important not to allow actions that are regarded as a provocation (incitement) of the suspect to commit a corruption offense.

The paper presents empirical research on personality factors of choosing adaptation strategies in a different cultural environment by labor migrants. The study determines three major adaptation strategies: integration, assimilation and marginalization. It establishes that integration and assimilation are means of solving the crisis of social identity. Personal identity acquires features of mature positive identity, when labor migrants integrate into a different cultural environment of a country of their employment. If a migrant chooses the strategy of assimilation, then personal identity has a tendency to approach to diffusive, “fuzzy” identity with indefinite life cycles, a decreased level of self-respect, a lack of internal integrity and uniformity. A marginal status of labor migrants in a country of employment causes an intensification of the crisis of personal identity, when migrants are not satisfied with the situation of employment abroad, but they do not see opportunities for self-realization in Ukraine. Factor analysis made it possible to establish an adaptation structure of labor migrants consisting of five major factors (72.43%).

Published: September 2020

The issue of national identity is multifaceted, disputable and extremely important in modern society, being one of the factors that determine its vitality. This paper presents the look at the problem from pedagogical perspective. The authors aim to explore the peculiarities of the formation of Ukrainian national identity in native intelligentsia under Ukrainian statelessness in Soviet times using the life and activity of Yurii Stupak as an example. Yurii Stupak is a notable representative of Ukrainian intelligentsia, an educator, scholar, literary studies expert, art critic, local history researcher, the author of numerous works in history of education and ethno-pedagogy. The study uses qualitative methodology and is founded on the laws and categories of scientific research. The researchers applied modern research approaches (personality oriented, cultural, personified, interdisciplinary) and methods (general scientific analysis, comparison, generalization, systematization; textual analysis, elaboration of the source base and historiographical work on the selected problem; the method of retrospective analysis). The authors have established that formation of the personality of Yurii Stupak as a teacher and scholar was influenced by numerous socio-political, socio-economic, cultural-educational and personal factors. The authors prove the decisive impact of family education and learning from nationally conscious teachers at higher education institutions as well as self-education and will for constant personal and professional development on facilitating the continuity of the process of formation of Ukrainian national identity in the native intelligentsia during the investigated period. It is confirmed that national identity does not depend on the existence of sovereign statehood, but it stimulates its revival.
Pharmacological Aspects and Clues for the Rational Use of Chloroquine / ydroxychloroquine Facing the Therapeutic Challenges of COVID-19 Pandemic
Authors: Noël François , Lima Jaderson
Published: September 2020

Since there is an urgent need for COVID-19 treatment, the pandemic disease caused by SARS-CoV-2, the repurposing of available drugs is a quick and cheap option, with chloroquine (CQ) and hydroxychloroquine (HCQ) being the most quoted drugs in this context. As a rigorous evaluation of the available data is needed to help to decide on the eventual use of these drugs, the first objective of this work is to critically review the available in vitro assay, clinical studies and putative mechanism(s) of action of CQ/HCQ concerning COVID-19, either alone or in association with azithromycin (AZM). The second objective is to discuss the drug alternatives to treat COVID-19, with emphasis on Brazil, Latin America, and countries where malaria is endemic. Finally, we describe some of the on-going international clinical trials and their therapeutic schemes. We conclude that: 1) there is a good rationale for HCQ use, at least within a compassionate approach, for COVID-19 treatment, possibly at not to severe stage of the disease; 2) the risk/benefit ratio of HCQ use alone or in combination with other drugs such as AZM has yet to be established with the available level of evidence, according to the evidence-based medicine principles.

Background. Distress is an unpleasant emotional experience of psychological, social or spiritual nature, which can interfere with the ability to cope. Objective. To describe the distress phenomenology in primary caregivers of adults with advanced cancer. Material and Methods. In this descriptive cross-sectional study we evaluated adults with advanced oncologic disease and their primary caregivers. A structured interview and clinimetric instruments (Palliative Performance Scale, Edmonton Symptom Assessment Scale, and The Distress Thermometer) were applied to estimate the frequency and severity of distress in both groups. We also examined possible variables associated with distress. Results. Information on 87 patient-caregiver dyads (n=174) was analyzed. Age was significantly lower in caregivers than in patients. Approximately half of the caregivers had a paid job; 38 % was a homemaker. The prevalence of distress was significantly higher among caregivers than their patients (86.2 % vs. 71.3 %, respectively; p=0.01). According to the caregivers, the main problems linked to distress were emotional (62 %) and practical (40 %); which contrasts with the patients, who claimed the main problems were physical (57 %), followed by emotional (36 %). Conclusions. The prevalence of distress among caregivers of patients with advanced disease is very high. Moreover, the frequency of perceived distress in caregivers is higher than their respective patients. The most heavily affected domain, perceived by caregivers is emotional, while in the patients it is mainly physical.

Introduction. Eradication rates of hepatitis C virus (HCV) infection is likely to rise after liver transplantation (LT). We aimed to evaluate the clinical role of a simple method for calcineurin inhibitors (CNI) adjustment in post-LT patients receiving paritaprevir / ritonavir / ombitasvir / dasabuvir and ribavirin (3D scheme). Material and Methods. We included post-LT adult patients between 2014 and 2017. All selected subjects had at least a 12-month follow-up receiving a stable dose of a CNI. All patients had HCV-1 infection, no liver cirrhosis and received the 3D scheme for 24 weeks. Serial blood concentration measurements of immunosuppressant drugs were obtained. CNI dose was adjusted since 3D scheme initiation and during follow-up until adequate levels were obtained. Results. A total of 10 LT patients (mean age 58.7 ± 11.26 years, 60 % women), out of LT 22, received the 3D regime. Tacrolimus was used in 9 patients: four patients received a dose of 0.5 mg every 10 days and 5 received doses of 0.25 mg every 5 days (mean levels, 9.07 ± 5.56 ng/mL). The trough concentration (Ctrough) was 2 ng / mL and the maximum concentration (Cmax) was 30 ng / mL. Only one patient was treated with cyclosporine (mean blood levels of 152.85 ± 54.55 ng / mL). All cases exhibited a sustained viral response. Discussion and Conclusions. It is possible to adjust CNI in LT patients under the 3D regime, with high response rates. Low CNI doses are required to avoid toxicity and side effects in HCV patients receiving protease inhibitors.
