Deep Learning of Sea Surface Temperature Patterns to Identify Ocean Extremes
Authors: Prochaska J. Xavier , Cornillon Peter C. , Reiman David M.
Published: February 2021

We performed an out-of-distribution (OOD) analysis of ∼12,000,000 semi-independent 128 × 128 pixel2 sea surface temperature (SST) regions, which we define as cutouts, from all nighttime granules in the MODIS R2019 Level-2 public dataset to discover the most complex or extreme phenomena at the ocean’s surface. Our algorithm (ULMO) is a probabilistic autoencoder (PAE), which combines two deep learning modules: (1) an autoencoder, trained on ∼150,000 random cutouts from 2010, to represent any input cutout with a 512-dimensional latent vector akin to a (non-linear) Empirical Orthogonal Function (EOF) analysis; and (2) a normalizing flow, which maps the autoencoder’s latent space distribution onto an isotropic Gaussian manifold. From the latter, we calculated a log-likelihood (LL) value for each cutout and defined outlier cutouts to be those in the lowest 0.1% of the distribution. These exhibit large gradients and patterns characteristic of a highly dynamic ocean surface, and many are located within larger complexes whose unique dynamics warrant future analysis. Without guidance, ULMO consistently locates the outliers where the major western boundary currents separate from the continental margin. Prompted by these results, we began the process of exploring the fundamental patterns learned by ULMO thereby identifying several compelling examples. Future work may find that algorithms such as ULMO hold significant potential/promise to learn and derive other, not-yet-identified behaviors in the ocean from the many archives of satellite-derived SST fields. We see no impediment to applying them to other large remote-sensing datasets for ocean science (e.g., SSH and ocean color).

Published: February 2021

Voice is one of the essential mechanisms for communicating and expressing one’s intentions as a human being. There are several causes of voice inability, including disease, accident, vocal abuse, medical surgery, ageing, and environmental pollution, and the risk of voice loss continues to increase. Novel approaches should have been developed for speech recognition and production because that would seriously undermine the quality of life and sometimes leads to isolation from society. In this review, we survey mouth interface technologies which are mouth-mounted devices for speech recognition, production, and volitional control, and the corresponding research to develop artificial mouth technologies based on various sensors, including electromyography (EMG), electroencephalography (EEG), electropalatography (EPG), electromagnetic articulography (EMA), permanent magnet articulography (PMA), gyros, images and 3-axial magnetic sensors, especially with deep learning techniques. We especially research various deep learning technologies related to voice recognition, including visual speech recognition, silent speech interface, and analyze its flow, and systematize them into a taxonomy. Finally, we discuss methods to solve the communication problems of people with disabilities in speaking and future research with respect to deep learning components.

Published: February 2021

This paper presents an underwater high-precision line laser three-dimensional (3D) scanning (LLS) system with rotary scanning mode, which is composed of a low illumination underwater camera and a green line laser projector. The underwater 3D data acquisition can be realized in the range of field of view of 50° (vertical) × 360° (horizontal). We compensate the refraction of the 3D reconstruction system to reduce the angle error caused by the refraction of light on different media surfaces and reduce the impact of refraction on the image quality. In order to verify the reconstruction effect of the 3D reconstruction system and the effectiveness of the refraction compensation algorithm, we conducted error experiments on a standard sphere. The results show that the system’s underwater reconstruction error is less than 0.6 mm within the working distance of 140 mm~2500 mm, which meets the design requirements. It can provide reference for the development of low-cost underwater 3D laser scanning system.

Published: February 2021

Recording human gestures from a wearable sensor produces valuable information to implement control gestures or in healthcare services. The wearable sensor is required to be small and easily worn. Advances in miniaturized sensor and materials research produces patchable inertial measurement units (IMUs). In this paper, a hand gesture recognition system using a single patchable six-axis IMU attached at the wrist via recurrent neural networks (RNN) is presented. The IMU comprises IC-based electronic components on a stretchable, adhesive substrate with serpentine-structured interconnections. The proposed patchable IMU with soft form-factors can be worn in close contact with the human body, comfortably adapting to skin deformations. Thus, signal distortion (i.e., motion artifacts) produced for vibration during the motion is minimized. Also, our patchable IMU has a wireless communication (i.e., Bluetooth) module to continuously send the sensed signals to any processing device. Our hand gesture recognition system was evaluated, attaching the proposed patchable six-axis IMU on the right wrist of five people to recognize three hand gestures using two models based on recurrent neural nets. The RNN-based models are trained and validated using a public database. The preliminary results show that our proposed patchable IMU have potential to continuously monitor people’s motions in remote settings for applications in mobile health, human–computer interaction, and control gestures recognition.

Published: February 2021

In this paper, we describe a long-range convex cavity-type passive ultra-high-frequency (UHF) radio frequency identification (RFID) tag to use on various metal and non-metal surfaces, for IoT sensor energy harvesting. The tag antenna is built on the 3D printed cavity structure with polylactic acid (PLA) plastic and painted with the conductive ink on the 1 mm protruding area (convex) of inner surface and the side-walls of the cavity structure to form a cavity structure. The tag is designed to operate in the UHF band (840–960 MHz). This long-range cavity tag antenna (CTA) works at both 920 MHz and 915 MHz UHF RFID frequencies. It provides a linear polarized (LP) frontal reading range of 35 m and side reading range above 15 m when mounted on either metal or non-metal objects. We describe the antenna characteristics, structure, modeling, simulation, and experimental results. A mathematical reading range also was calculated and compared with experimental data.

Authors: Łapko Aleksandra , Hącia Ewa , Wieczorek Radosław
Published: February 2021

The aim of this study was to examine the issue of waste collection from passenger ships in tourist port cities using the example of Świnoujście, Poland. This is an important issue from the perspective of sustainable development, including that of tourism, because an improperly organized waste collection process may endanger the natural environment and disrupt the life of the local community. After the analysis of the types of waste generated on vessels, the means of transport used for their collection were identified with particular regard to those used at the seaport in Świnoujście, a tourist city. The selected waste quantities collected from ships in 2017–2019 were quantitatively analyzed. In addition, the number of waste collections was analyzed in the context of the number of vehicles involved in this process. The latter element is important in terms of impact on the port city’s transport system, which has a spa and tourist function.

Published: February 2021

Porous asphalt (PA) mixtures are more environmentally friendly but have lower durability than dense-graded mixtures. Additives can be incorporated into PA mixtures to enhance their mechanical strength; however, they may compromise the hydraulic characteristics, increase the total cost of pavement, and negatively affect the environment. In this paper, PA mixtures were produced with 5 different types of additives including 4 fibers and 1 filler. Their performances were compared with the reference mixtures containing virgin bitumen and polymer-modified bitumen. The performance of all mixes was assessed using: mechanical, hydraulic, economic, and environmental indicators. Then, the Delphi method was applied to compute the relative weights for the parameters in multi-criteria decision-making methods. Evaluation based on distance from average solution (EDAS), technique for order of the preference by similarity to ideal solution (TOPSIS), and weighted aggregated sum product assessment (WASPAS) were employed to rank the additives. According to the results obtained, aramid pulp displayed comparable and, for some parameters such as abrasion resistance, even better performance than polymer-modified bitumen, whereas cellulose fiber demonstrated the best performance regarding sustainability, due to economic and environmental benefits.
A Relationship between Supply Chain Practices, Environmental Sustainability and Financial Performance: Evidence from Manufacturing Companies in Jordan
Authors: Jum’a Luay , Zimon Dominik , Ikram Muhammad
Published: February 2021

Pursuing sustainable development creates competitiveness for manufacturing firms in the market, however the financial pressure of adopting sustainable environmental practices is still a major concern. Few studies were found on the inter-relationships between supply chain management practices, environmental sustainability, and firm financial performance. Moreover, manufacturing companies are compelled by different pressure groups across the globe to maintain environmental standards while conducting their business and supply chain activities. Therefore, the current study aims to investigate the impact of supply chain practices on environmental sustainability and financial performance. In addition, the role of environmental sustainability as a mediator between supply chain management and financial performance was analyzed to improve sustainable development. A well-designed questionnaire was administered to manufacturing companies in Jordan for data collection. A total of 376 responses were analyzed and the proposed hypotheses were tested by using Structural Equation Modelling (SEM) approach. The results reveal that environmental sustainability was tested significantly and influenced by supply chain practices such as relationship with customers, postponement, level of information sharing, and information quality. Whereas environmental sustainability had a significant direct effect on financial performance. Finally, environmental sustainability mediated the relationship of all supply chain management practices with financial performance except strategic supplier partnership dimension. The study provides policy guidelines to decision makers while simultaneously assists the managers to improve sustainability practices in manufacturing companies.

Published: February 2021

Vulnerability assessment varies widely across households, countries, and regions. Though many previous studies assessed vulnerability to climate change, their unit of analysis was aggregate. Therefore, the objective of this study was to measure the vulnerability of smallholder farmers to climate change at the household level and identify its determinant factors in east Hararghe zone. A multi-stage sampling procedure was used to select districts, kebeles, and sample respondents. Vulnerability as expected poverty approach was used to measure household-level vulnerability. Logit model was also used to assess factors contributing to households’ vulnerability. The study revealed that 73% of households were vulnerable to climate-induced shocks. Households with better farm experience, land size, livestock ownership, access to credit, access to extension service, social capital, access to climate information, non-farm income, and headed by a male were not vulnerable to climate change; whereas households who were living in low and midland agro-ecologies, far from the market, and participating in productive safety-net programs were vulnerable to climate change. The study indicated that the vulnerability of smallholder farmers was sensitive to the minimum income required to maintain daily life. Income-generating activities that supplement farm income should be well designed in policy to reduce the vulnerability of smallholder farmers.
Effective Scalar Potential in Asymptotically Safe Quantum Gravity
Authors: Wetterich Christof
Published: February 2021

We compute the effective potential for scalar fields in asymptotically safe quantum gravity. A scaling potential and other scaling functions generalize the fixed point values of renormalizable couplings. The scaling potential takes a non-polynomial form, approaching typically a constant for large values of scalar fields. Spontaneous symmetry breaking may be induced by non-vanishing gauge couplings. We strengthen the arguments for a prediction of the ratio between the masses of the top quark and the Higgs boson. Higgs inflation in the standard model is unlikely to be compatible with asymptotic safety. Scaling solutions with vanishing relevant parameters can be sufficient for a realistic description of particle physics and cosmology, leading to an asymptotically vanishing “cosmological constant” or dynamical dark energy.
Challenges and Possibilities of Cell-Based Tissue-Engineered Vascular Grafts
Authors: Saito Junichi , Kaneko Makoto , Ishikawa Yoshihiro , Yokoyama Utako
Published: February 2021

There is urgent demand for biologically compatible vascular grafts for both adult and pediatric patients. The utility of conventional nonbiodegradable materials is limited because of their thrombogenicity and inability to grow, while autologous vascular grafts involve considerable disadvantages, including the invasive procedures required to obtain these healthy vessels from patients and insufficient availability in patients with systemic atherosclerosis. All of these issues could be overcome by tissue-engineered vascular grafts (TEVGs). A large body of evidence has recently emerged in support of TEVG technologies, introducing diverse cell sources (e.g., somatic cells and stem cells) and novel fabrication methods (e.g., scaffold-guided and self-assembled approaches). Before TEVG can be applied in a clinical setting, however, several aspects of the technology must be improved, such as the feasibility of obtaining cells, their biocompatibility and mechanical properties, and the time needed for fabrication, while the safety of supplemented materials, the patency and nonthrombogenicity of TEVGs, their growth potential, and the long-term influence of implanted TEVGs in the body must be assessed. Although recent advances in TEVG fabrication have yielded promising results, more research is needed to achieve the most feasible methods for generating optimal TEVGs. This article reviews multiple aspects of TEVG fabrication, including mechanical requirements, extracellular matrix components, cell sources, and tissue engineering approaches. The potential of periodic hydrostatic pressurization in the production of scaffold-free TEVGs with optimal elasticity and stiffness is also discussed. In the future, the integration of multiple technologies is expected to enable improved TEVG performance.
The Conquest of Representation in the Architecture of Guatemala
Authors:   University of Minnesota, Piotrowski Andrzej
Published: February 2021

This paper will argue that the connections that exist between architecture and political powers are located in representational functions of architecture. Representation is defined here as a culture-specific process of establishing the relationships between reality and the signs created to symbolize that reality. Architecture of Guatemala provides a unique material to study how representational constitution of symbolic places reflects an ideological struggle of two different cultures. To substantiate this point, I will expand on Tzvetan Todorov’s observations made in “The Conquest of America” and show how they could enhance our understanding of the symbolic function of architecture. The discussion of representational attributes and workings of architecture will be informed by a comparative reading of three cities in Guatemala: Mayan ruins in Tlkal, colonial city of Antigua, and indigenous Chichicastenango. My objective is to test the workings of this critical inquiry against the geography of power that these three cities represent.

The monograph is devoted to the expert study of the dangers of typical mistakes made by air traffic controllers in their professional activities. Taking into account the influence of the human factor on flight safety and ICAO recommendations, an up-to-date list of n = 21 typical errors was formulated and the systems of preferences of air traffic controllers on their dangers were comprehensively studied. The differential method for establishing a comparable risk of errors has been substantiated and implemented, as well as the α-method (α-coefficient) for establishing the degree of coincidence of the advantages different systems, which is based on comparing the same errors not by the ranks that they occupy in different systems of advantages, but by the corresponding these ranks of nonlinear significance coefficients. The methodology for a comprehensive assessment of error threats has been substantiated and implemented, based on the qualitative (linguistic) indicators of their hazards and frequency of manifestation recommended by ICAO. The use of a multiplicative approach contributes to obtaining more reliable results that help prevent statistical errors of the I-II kind. Using the methods of the pattern recognition theory, a multi-step technology for detecting and filtering out marginal opinions has been developed and implemented, which makes it possible to build group preference systems with the required level of the opinions consistency. The development of the methodology for the application of classical decision-making criteria as strategies for building group preference systems with different levels of risk was implemented. The normalized index of indistinguishability of error hazards was introduced. The Kemeny median for nonparametric optimization of consistent group preference systems on error hazards was applied. Defuzzification of qualitative rank estimates of error hazards by providing them with the corresponding weighted significance coefficients has been carried out. The hypothesis about the possible influence of cross-cultural factors on the attitude to the dangers of errors of Ukrainian and Azerbaijani air traffic controllers was tested. The monograph is addressed to scientists and specialists who deal with the problems of the influence of the human factor on flight safety. It can be useful in the educational process of aviation operators of the "front line" (air traffic controllers and flight crew members), as well as in providing methodological content of flight safety management systems. Given the versatility of the improved and developed methods, it can also be useful for scientists and specialists who use expert technologies in their activities.

The Epileptic seizure is one of major neurological brain disorders and about 50 million of world’s population is affected by it. Electroencephalography is medical test which records brain signal by mounting electrodes on scalp or brain cortex to diagnosis seizure. Scalp Electroencephalography has low spatial resolution and presence of external artifact as compared to Intracranial Electroencephalography. In Intracranial Electroencephalography strip, grid and depth type of electrodes are implanted on cortex of brain by surgery to measure brain signal. Analysis of brain signal was carried out in past in diagnosis of Epileptic seizure. Seizure classification and Severity measurement of Epileptic Seizure are still challenging areas of research. Seizures are classified as focal seizure, generalized and secondary generalized seizure depending upon the area of brain which it generates and how it spreads. Classification of seizure helps in treatment of seizure and during brain surgery to operate on brain part which is responsible for continuous seizures generation. Developed seizure classification algorithm classifies seizures as focal Seizure, generalized Seizure and secondary generalized seizure depending on the percentage of iEEG electrodes detecting seizure activity. Seizure severity measurement scale is developed by modification in National Hospital Seizure Severity Scale. Seizures are graded as Mild seizure, Moderate seizure and severe seizure depending on its severity. Seizure Classification and Seizure Severity Measurement improves life quality of Epileptic patients by proper drug management.

This paper addresses the development of High Performance Concrete in the past along with the experimental work on properties of Slurry Infiltrated Fibrous Concrete (SIFCON). Slurry infiltrated fibrous concrete has high strength, large ductility and good performance under seismic excitations. There is an increase in numbers of structures testified by the recent symposiums and conferences held on HPFRC. Now presently investigations are being carried out to suggest recommendations for the design of HPFRC structures. SIFCON consist of cement slurry and different types of steel fibers. It is observed that with the increase in percentage of steel fibers there is an improved static, dynamic and mechanical properties of concrete. Steel fibers also act as crack arrester and improve durability. In the present study, it is observed that at 9% fiber content the compressive strength, split tensile strength and flexural strength is optimum.

Managing plastic waste is a global challenge that challenges the protection of our ecosystem due to its high rate of generation and its non-biodegradability. PWs must, however, be carefully handled to mitigate the emissions involved with their incineration and dumping into landfills. Plastic waste can be recycled into new usable building materials. In this analysis, shredded PET waste aggregate from a recycling center was heated at 230 0C and used as a binding aggregate incomplete replacement of cement with river sand to produce floor tiles. The properties of the aggregate materials and roof tiles (including their distribution of particle size, silt, clay and dust content, relative density, water absorption, porosity, flexural and compressive strength) were tested on different PET waste: sand mixing ratio, 100%, 90%, 70%, 50%, and 30%. Results revealed that the tiles produced by 30% PET and 70% river sand (3:7) achieved higher density, flexural and compressive strength than the other percentages of the mixture. The compressive strength of the tiles produced with 30 percent PET waste composition was greater than that of cement concrete (at 28 days of curing) for residential buildings. As a result of this low water absorption and eco-friendliness, PET waste can be used for roof tiles at 30 percent PET substitution based on the test results.

El proceso de profesionalización de todo estudiante universitario requiere la elaboración de un proyecto de investigación en el que aplica los aprendizajes adquiridos a lo largo de sus estudios. Se pondrán en práctica procesos de indagación con el adecuado rigor académico, aportando un estudio original teórico y/o práctico para su posterior divulgación científica. Este capítulo pretende dar una visión general de cómo abordar el comienzo de un trabajo fin de máster. Se debe encontrar la motivación adecuada para conseguir la implicación del discente en esta tarea. Se partirá de la búsqueda de un tema innovador y original, sobre el cual se buscarán los principales estudios precedentes, que permitirán concretar esta idea inicial que marcará las posteriores fases. Será el momento de plantear el problema de la investigación a través de la formulación de hipótesis que más adelante se contrastarán. Para determinar una buena línea de investigación, será necesario determinar unos objetivos, preguntas, justificación y viabilidad de todo el proceso. De esta forma, se podrá elaborar un trabajo que contribuya a fomentar el conocimiento científico para futuras investigaciones que se realicen sobre el tema.

La investigación en la actualidad tiene el reto de generar conocimiento que sea socialmente útil. Este capítulo presenta reflexiones sobre este proceso tan importante y poco estudiado, planteando algunas propuestas muy útiles para investigadores y estudiantes que están desarrollando sus proyectos de fin de titulación (TFG, TFM, tesis). Para ello, el texto se ha organizado en tres apartados. En el primero, se efectúa el análisis de diferentes referentes sobre la transferencia de conocimiento en España, ubicándola como tercer pilar de la universidad y formulando precisamente la necesidad de que el conocimiento fluya constantemente entre la universidad y la sociedad. En el segundo apartado se ofrecen ejemplos de transferencia de conocimiento en el campo de Educación y de las Ciencias Sociales y Humanas. Se resalta cómo diversas experiencias han logrado articular el desarrollo social con procesos de formación o mediante la producción de conocimiento tecnológico y científico. Además, se presenta un sistema de indicadores útil para que los estudiantes que están desarrollando sus proyectos fin de título puedan diseñar diversas acciones en relación con la transferencia de conocimiento social. En el tercer y último apartado, se describen posibles formas de transferencia de conocimiento social, teniendo en cuenta los espacios de acción de los servicios educativos, sociales y comunitarios y las trayectorias de los equipos de estos servicios. Finalmente, se detallan las posibles relaciones entre las sociedades del nuevo milenio y la formación, la investigación, la perspectiva internacional y la acción socioeducativa en el ámbito de la transferencia de conocimiento social.

El desarrollo de un trabajo fin de máster debe ser un proceso riguroso y sistemático, en el cual los estudiantes utilicen un método de investigación que les permita alcanzar los objetivos previstos. Esto no es tarea sencilla, por lo cual el propósito de este capítulo es llevar a cabo una descripción de las diferentes opciones disponibles para diseñar una investigación educativa que ayude a planificar el trabajo de campo que dé respuesta a los objetivos planteados en el trabajo fin de máster. En el texto se establece una diferenciación conceptual entre método y diseño de investigación, se describen las características del enfoque cuantitativo y cualitativo y las finalidades, básica y aplicada, de la investigación educativa. Para terminar, se realiza una clasificación de los diseños más comunes de la investigación educativa diferenciando entre diseños cuantitativos (experimentales y no experimentales) y diseños cualitativos (con una finalidad básica y con una finalidad aplicada). La elección del enfoque y el diseño de investigación dependerán del problema de investigación planteado; será este el que guíe la toma de decisiones sobre el diseño del trabajo de campo.
PREVALENCE OF DYSLIPIDEMIA IN CHRONIC KIDNEY DISEASE
Authors: Bhavana P. Lakshmi , Lokendranath G. , Kumar G. Vijaya
Published: February 2021

BACKGROUND: Chronic kidney disease (CKD) is a worldwide health problem with increasing incidence and
prevalence. The annual mortality rate of patients undergoing dialysis is more than 20%. The leading causes of morbidity
and mortality in CKD are cardiovascular diseases, primarily atherosclerotic coronary artery disease. Dyslipidemia is a common complication of
CKD. It is a signicant risk factor for the development of cardiovascular disease. Alteration in lipid prole correlates with declining glomerular
ltration rate (GFR) and degree of proteinuria.
AIM:
Ÿ To identify the altered lipid prole in patients with chronic kidney disease.
Ÿ To note the alterations in different lipoprotein fractions in chronic kidney disease patients.
Ÿ To note the difference in lipid prole in CKD patients on conservative management and maintenance hemodialysis.
MATERIALS AND METHODS: A Hospital-based observational Prospective study was conducted in the Department of Medicine, Santhiram
medical college, and general hospital for six months. Chronic kidney disease patients who are non-diabetic were taken for the study with
informed and written consent taken from the patient.
RESULTS: Plasma triglycerides(153.14±54.37mg/dl) were elevated, and plasma HDL (36±43.5mg/dl) was decreased in CKD patients. There
is no signicant elevation of total cholesterol levels. On comparing lipid proles of CKD patients on conservative management and
hemodialysis, there was a signicant increase in triglycerides in the hemodialysis group.
CONCLUSION: Signicant elevation of triglycerides and VLDL was observed in patients of CKD on hemodialysis. Further, a reduced HDL
cholesterol level was also observed in both conservative and hemodialysis groups of CKD patients. Dyslipidemia observed in Uremic patients
may contribute to accelerated atherosclerosis and further progression of chronic renal failure.
Chronotopes of Affectivity in Literature. On Melancholy, Estrangement, and Reflective Nostalgia
Authors: Salmon Laura
Published: February 2021

Basing our analysis on the concepts of ‘emotion’, ‘feeling’, and ‘mood’ as defined by data from the cognitive sciences, we argue that human emotions are both universal and intrinsically linked to literary and artistic chronotopes. In her study of 'reflective' and 'restorative' nostalgia, Svetlana Boym (2001) shows that 'nostalgia' itself represents pure ambivalence that takes on a particular shape in response to the mood, thoughts, and psychological state of the author. Its ultimate expression might assume the form of either monological ideology or of paradoxical existential emotion. It is this second type of nostalgia that we can link most closely link to understandings of both 'melancholy' and 'identity' or 'self-consciousness'. Brooding and melancholic toska is shared by persons who suffer from what we might call 'existential ambivalence'; these persons are 'mercurials' in the terminology of Yuri Slezkine (2004). Within the field of Russian literature, this 'mercurial' sense of melancholy is particularly well developed.
