Abstract The results of studies of the optical and transport properties of epitaxial Pb_0.74Sn_0.26Te(In) films with a differently treated surface are presented. A comparative analysis of the results makes it possible to establish that the characteristic features of the photoconductivity spectra are defined by processes in the bulk while the surface states have practically no effect on the spectra. At the same time, the photoresponse kinetics and the rate of relaxation processes are heavily dependent on the state of the surface. The characteristic relaxation times of nonequilibrium charge carriers (about several milliseconds) are such that it is possible to use the methods of standard Fourier-transform spectroscopy to characterize optical transitions in the bulk.
Электронные состояния доноров V группы в германии: вариационный расчет с учетом короткодействующего потенциала

In the framework of the envelope function approximation, the wave functions of low-lying 1s(A1), 2s, 2p0, 2p±, 3p0 states of shallow donor centers P, As, Sb in germanium are calculated considering the short-range part of the impurity potential. The latter is constructed individually for each impurity, taking into account the spatial dispersion of the dielectric function and the difference between the ionic cores of germanium and the impurity center. The envelope function equation was solved using the Ritz variational method, and selected trial wave functions of the orbitally non-degenerate s-states are characterized by two spatial scales: the first one is of the order of the donor effective Bohr radius and corresponds to the long-range part of the potential, and the second one, which is an order of magnitude less, simulates the electron response to the short-range part of the donor potential. The electron density in the donor ground state is shifted to the nucleus due to the attractive “central cell” correction. The envelope functions of p-states, in turn, are constructed in such a way they are orthogonal to the ground state envelope functions for each impurity center, and, unlike previous works, are different for various donors.

Published: June 2020

A mechanism of amplification of interaction between optical radiation and superconducting niobium nitride thin film placed on the surface of optical waveguides, which are fabricated on lithium niobate substrate, is investigated. This effect can be obtained with help of an additional covering layer with high refractive index. It was shown that adiabatic deformation of waveguide modes can increase absorption of light in a superconducting layer up to ~ 1 dB/µm, making it possible to fabricate a SSPD on lithium niobate with quantum efficiency of about 70%.

Published: June 2020

A three-layer structure consisting of a nonlinear optical medium with a stepwise change in the dielectric constant inside which there is a dielectric layer of finite thickness is considered. The surface waves of two types of symmetry with a special field structure can propagate along the layers. Domains of finite width with different optical properties in the border regions in a nonlinear medium are formed. The formation of domains, as well as the existence of surface waves, occurs at interlayer thicknesses not exceeding a certain critical value.
Dificultades de comprensión y conflictos epistémicos al hacer transformaciones en las representaciones de una función
Authors: Meza Sarmiento Fabián , Amaya de Armas Tulio
Published: June 2020

En este trabajo se tuvo como objetivo analizar los conflictos epistémicos que tienen los estudiantes del grado once al realizar transformaciones con los elementos de una función. La muestra la constituyeron 85 estudiantes del grado once, con edades entre 16 y 18 años de la Institución Educativa San Vicente de Paul en el departamento de Sucre. La investigación se desarrolló en cuatro etapas: revisión documental, diseño, validación y aplicación de instrumentos y análisis e interpretación de resultados. Los resultados evidencian serias dificultades relacionadas con: el reconocimiento de los elementos de una función y sobre cómo éstos se relacionan y en el establecimiento de congruencias entre los elementos de dos o más representaciones. Los principales conflictos epistémicos que se han encontrado se relacionan con el reconocimiento de la función en contextos académicos, no reconocen las representaciones gráficas ni tabulares como representaciones de una función y por tanto pocos las usan como apoyo para dar sus respuestas, el uso indistinto de la letra como magnitud y como variable generalizada, la construcción de intervalos inapropiado donde se tenían en cuenta sólo uno de los límites de éstos, la construcción de gráficos apropiados, pero no convencionales, en los cuales se tomó al revés, la orientación del eje X y el reconocimiento sólo de la representación analítico aritmética y la analítico algebraica, como representaciones de una función.

Resumen
El presente ensayo busca hacer un rescate histórico acerca del papel que representa la Lengua Inglesa en la actualidad. Los datos traídos por Crystal (2011) comprueban que existen actualmente más personas extranjeras que se comunican a través de esta lengua que los propios nativos. Esto hace que se convierta en una lengua de aspecto global. ¿Pero qué hace que se considere una lengua global? ¿Su estructura gramatical? ¿El número de personas que se expresan por ella? De tal forma, por medio de una revisión bibliográfica de su papel representado en la actualidad, se trazó un contexto histórico donde el inglés está asociado con el poderío militar y político ligado a esta lengua.

Esta investigación se fundamenta en la planificación, desarrollo y análisis de actividades puntuales en el contexto de una unidad didáctica de la Lengua Extranjera inglés. Dicha unidad didáctica está basada en el enfoque de la tarea final, en la que se concluye cada una de las unidades con una actividad que engloba todo lo trabajado anteriormente. Se analizan y estudian los resultados de dos actividades puntuales de carácter colaborativo en términos de motivación del alumnado dentro del proceso de enseñanza-aprendizaje así como sus consecuencias positivas en la adquisición del conocimiento. En concreto, una de ellas es un juego colaborativo con el que se han estudiado los papeles de la competitividad y el trabajo entre iguales y sus respectivas potencialidades didácticas. Por otro lado, la segunda actividad que entra en juego en esta investigación es el conjunto final de actividades de la unidad, denominada tarea final, y que contiene una serie de actividades de carácter tanto colaborativo como motivacional y, por tanto, de gran relevancia para este estudio.
La ética como problema filosófico de la educación
Authors: Moreau Didier
Published: June 2020

Este artículo se produce en el contexto del Seminario Internacional sobre Educación y Emancipación entre conversión y metamorfosis desarrollado en el marco del proyecto PREFALC, programa de apoyo a la formación e investigación en cooperación internacional de nivel de maestría, que el gobierno francés financia con las universidades francesas y sus pares en América Latina y el Caribe, en su versión 2018-2019, denominado “Reescrituras de las emancipaciones y de la modernidad en el gran Caribe” Francia-Colombia. Se ofrece una panorámica breve en tono reflexivo sobre la relación entre ética y filosofía hoy y su relevancia permanente como cuestión en educación. En los planteamientos se ilustra con principios problematizados desde el estoicismo en contraste con las pedagogías pastorales. Se deriva hacia la definición de la emancipación y la metamorfosis donde la educación se concebiría como práctica para que los sujetos se mejoren a sí mismos éticamente, lo cual interroga las prácticas escolares y las mediaciones para la formación moral. Esta reflexión pone su centro en cómo aún desde lo restringido de la institucionalización de los sistemas educativos, en el ámbito de lo cotidiano existe una libertad pedagógica en la que el educador puede no solo transformarse a sí mismo, sino proveer la oportunidad a los estudiantes para la emancipación y la superación en autonomía moral. El artículo deja un cuestionamiento sobre las prácticas en educación y su verdadera coherencia con la aspiración de propiciar un aprendizaje a lo largo de toda la vida.
Cost-Effective Smartphone-Based Articulable Endoscope Systems for Developing Countries: Instrument Validation Study
Authors: Moon Youngjin , Oh Jeongmin , Hyun Jaeho , Kim Youngkyu , Choi Jaesoon , Namgoong Jeongman , Kim Jun Ki
Published: June 2020

Background

Endoscopes are widely used for visualizing the respiratory tract, urinary tract, uterus, and gastrointestinal tracts. Despite high demand, people in underdeveloped and developing countries cannot obtain proper access to endoscopy. Moreover, commercially available endoscopes are mostly nonarticulable as well as not actively controlled, limiting their use. Articulating endoscopes are required for some diagnosis procedures, due to their ability to image wide areas of internal organs. Furthermore, actively controlled articulating endoscopes are less likely to harm the lumen than rigid endoscopes because they can avoid contact with endothelial tissues.

Objective

The study aimed to demonstrate the feasibility and acceptability of smartphone-based wide-field articulable endoscope system for minimally invasive clinical applications in developing and less developed countries.

Methods

A thin articulable endoscope system that can be attached to and actively controlled by a smartphone was designed and constructed. The system consists of a flexible endoscopic probe with a continuum mechanism, 4 motor modules for articulation, a microprocessor for controlling the motor with a smartphone, and a homebuilt app for streaming, capturing, adjusting images and video, and controlling the motor module with a joystick-like user interface. The smartphone and motor module are connected via an integrated C-type On-The-Go (OTG) USB hub.

Results

We tested the device in several human-organ phantoms to evaluate the usability and utility of the smartphone-based articulating endoscope system. The resolution (960 × 720 pixels) of the device was found to be acceptable for medical diagnosis. The maximum bending angle of 110° was designed. The distance from the base of the articulating module to the tip of the endoscope was 45 mm. The angle of the virtual arc was 40.0°, for a curvature of 0.013. The finest articulation resolution was 8.9°. The articulating module succeeded in imaging all 8 octants of a spherical target, as well as all 4 quadrants of the indices marked in human phantoms.

Conclusions

The portable wide-field endoscope was successfully controlled using a smartphone, yielding clear images with a resolution of 960 × 720 pixels at realistic focal distances. Actively and precisely controlled articulating movements have resulted in minimally invasive monitoring in the narrow space of internal organs providing a wide-area view. We found our smartphone-based active articulated endoscope to be suitable for point-of-care applications in developing and less developed countries.

Authors: Visweswaran Shyam , Colditz Jason B , O’Halloran Patrick , Han Na-Rae , Taneja Sanya B , Welling Joel , Chu Kar-Hai , Sidani Jaime E , Primack Brian A
Published: June 2020

Background

Twitter presents a valuable and relevant social media platform to study the prevalence of information and sentiment on vaping that may be useful for public health surveillance. Machine learning classifiers that identify vaping-relevant tweets and characterize sentiments in them can underpin a Twitter-based vaping surveillance system. Compared with traditional machine learning classifiers that are reliant on annotations that are expensive to obtain, deep learning classifiers offer the advantage of requiring fewer annotated tweets by leveraging the large numbers of readily available unannotated tweets.

Objective

This study aims to derive and evaluate traditional and deep learning classifiers that can identify tweets relevant to vaping, tweets of a commercial nature, and tweets with provape sentiments.

Methods

We continuously collected tweets that matched vaping-related keywords over 2 months from August 2018 to October 2018. From this data set of tweets, a set of 4000 tweets was selected, and each tweet was manually annotated for relevance (vape relevant or not), commercial nature (commercial or not), and sentiment (provape or not). Using the annotated data, we derived traditional classifiers that included logistic regression, random forest, linear support vector machine, and multinomial naive Bayes. In addition, using the annotated data set and a larger unannotated data set of tweets, we derived deep learning classifiers that included a convolutional neural network (CNN), long short-term memory (LSTM) network, LSTM-CNN network, and bidirectional LSTM (BiLSTM) network. The unannotated tweet data were used to derive word vectors that deep learning classifiers can leverage to improve performance.

Results

LSTM-CNN performed the best with the highest area under the receiver operating characteristic curve (AUC) of 0.96 (95% CI 0.93-0.98) for relevance, all deep learning classifiers including LSTM-CNN performed better than the traditional classifiers with an AUC of 0.99 (95% CI 0.98-0.99) for distinguishing commercial from noncommercial tweets, and BiLSTM performed the best with an AUC of 0.83 (95% CI 0.78-0.89) for provape sentiment. Overall, LSTM-CNN performed the best across all 3 classification tasks.

Conclusions

We derived and evaluated traditional machine learning and deep learning classifiers to identify vaping-related relevant, commercial, and provape tweets. Overall, deep learning classifiers such as LSTM-CNN had superior performance and had the added advantage of requiring no preprocessing. The performance of these classifiers supports the development of a vaping surveillance system.
Rejected Online Feedback From a Swiss Physician Rating Website Between 2008 and 2017: Analysis of 2352 Ratings
Authors: McLennan Stuart
Published: June 2020

Background

Previous research internationally has only analyzed publicly available feedback on physician rating websites (PRWs). However, it appears that many PRWs are not publishing all the feedback they receive. Analysis of this rejected feedback could provide a better understanding of the types of feedback that are currently not published and whether this is appropriate.

Objective

The aim of this study was to examine (1) the number of patient feedback rejected from the Swiss PRW Medicosearch, (2) the evaluation tendencies of the rejected patient feedback, and (3) the types of issues raised in the rejected narrative comments.

Methods

The Swiss PRW Medicosearch provided all the feedback that had been rejected between September 16, 2008, and September 22, 2017. The feedback were analyzed and classified according to a theoretical categorization framework of physician-, staff-, and practice-related issues.

Results

Between September 16, 2008, and September 22, 2017, Medicosearch rejected a total of 2352 patient feedback. The majority of feedback rejected (1754/2352, 74.6%) had narrative comments in the German language. However, 11.9% (279/2352) of the rejected feedback only provided a quantitative rating with no narrative comment. Overall, 25% (588/2352) of the rejected feedback were positive, 18.7% (440/2352) were neutral, and 56% (1316/2352) were negative. The average rating of the rejected feedback was 2.8 (SD 1.4). In total, 44 subcategories addressing the physician (n=20), staff (n=9), and practice (n=15) were identified. In total, 3804 distinct issues were identified within the 44 subcategories of the categorization framework; 75% (2854/3804) of the issues were related to the physician, 6.4% (242/3804) were related to the staff, and 18.6% (708/3804) were related to the practice. Frequently mentioned issues identified from the rejected feedback included (1) satisfaction with treatment (533/1903, 28%); (2) the overall assessment of the physician (392/1903, 20.6%); (3) recommending the physician (345/1903, 18.1%); (4) the physician’s communication (261/1903, 13.7%); (5) the physician’s caring attitude (220/1903, 11.6%); and (6) the physician’s friendliness (203/1903, 10.6%).

Conclusions

It is unclear why the majority of the feedback were rejected. This is problematic and raises concerns that online patient feedback are being inappropriately manipulated. If online patient feedback is going to be collected, there needs to be clear policies and practices about how this is handled. It cannot be left to the whims of PRWs, who may have financial incentives to suppress negative feedback, to decide which feedback is or is not published online. Further research is needed to examine how many PRWs are using criteria for determining which feedback is published or not, what those criteria are, and what measures PRWs are using to address the manipulation of online patient feedback.
Googling Musculoskeletal-Related Pain and Ranking of Medical Associations’ Patient Information Pages: Google Ads Keyword Planner Analysis
Authors: Yamaguchi Yoichiro , Lee Deokcheol , Nagai Takuya , Funamoto Taro , Tajima Takuya , Chosa Etsuo
Published: June 2020

Background

Most people currently use the internet to obtain information about many subjects, including health information. Thus, medical associations need to provide accurate medical information websites. Although medical associations have their own patient education pages, it is not clear if these websites actually show up in search results.

Objective

The aim of this study was to evaluate how well medical associations function as online information providers by searching for information about musculoskeletal-related pain online and determining the ranking of the websites of medical associations.

Methods

We conducted a Google search for frequently searched keywords. Keywords were extracted using Google Ads Keyword Planner associated with “pain” relevant to the musculoskeletal system from June 2016 to December 2019. The top 20 search queries were extracted and searched using the Google search engine in Japan and the United States.

Results

The number of suggested queries for “pain” provided by Google Ads Keyword Planner was 930 in the United States and 2400 in Japan. Among the top 20 musculoskeletal-related pain queries chosen, the probability that the medical associations’ websites would appear in the top 10 results was 30% in the United States and 45% in Japan. In five queries each, the associations’ websites did not appear among the top 100 results. No significant difference was found in the rank of the associations’ website search results (P=.28).

Conclusions

To provide accurate medical information to patients, it is essential to undertake effective measures for search engine optimization. For orthopedic associations, it is necessary that their websites should appear among the top search results.
Communication Behavior Changes Between Patients With Diabetes and Healthcare Providers Over 9 Years: Retrospective Cohort Study (Preprint)
Authors: Benis Arriel , Barak Barkan Refael , Sela Tomer , Harel Nissim
Published: June 2020

BACKGROUND

Health organizations and patients interact over different communication channels and are harnessing digital communications for this purpose. Assisting health organizations to improve, adapt, and introduce new patient–health care practitioner communication channels (such as patient portals, mobile apps, and text messaging) enhances health care services access.

OBJECTIVE

This retrospective data study aims to assist health care administrators and policy makers to improve and personalize communication between patients and health care professionals by expanding the capabilities of current communication channels and introducing new ones. Our main hypothesis is that patient follow-up and clinical outcomes are influenced by their preferred communication channels with the health care organization.

METHODS

This study analyzes data stored in electronic medical records and logs documenting access to various communication channels between patients and a health organization (Clalit Health Services, Israel). Data were collected between 2008 and 2016 from records of 311,168 patients diagnosed with diabetes, aged 21 years and over, members of Clalit at least since 2007, and still alive in 2016. The analysis consisted of characterizing the use profiles of communication channels over time and used clustering for discretization purposes and patient profile building and then a hierarchical clustering and heatmaps to visualize the different communication profiles.

RESULTS

A total of 13 profiles of patients were identified and characterized. We have shown how the communication channels provided by the health organization influence the communication behavior of patients. We observed how different patients respond differently to technological means of communication and change or don’t change their communication patterns with the health care organization based on the communication channels available to them.

CONCLUSIONS

Identifying the channels of communication within the health organization and which are preferred by each patient creates an opportunity to convey messages adapted to the patient in the most appropriate way. The greater the likelihood that the therapeutic message is received by the patient, the greater the patient's response and proactiveness to the treatment will be.

Community Gardening as a Way to Build Cross-Cultural Community Resilience through Increased Fresh-Food Access and Citizenship: A Community-based Participatory Research Proposal (Preprint)
Authors: Mejia Angie
Published: June 2020

UNSTRUCTURED

Community-based agriculture has been found to decrease food insecurity and ameliorate population health inequities. Furthermore, community gardens have been found to provide a connected set of benefits to intersectionally diverse gardeners: a sense of ownership, resources to help integration within new communities, and a space to nurture existing cultural identities. This sense of belonging in connection with access to community garden plots has been linked to psychological well-being and resilience. However, there is little knowledge on how psychosocial benefits connected to plot ownership affect resilience and which aspects of resilience in this process are salient. This community-based participatory research projects will examine the role of community gardens in decreasing food insecurity and facilitating various forms of resilience in various food-insecure groups of people residing in Rochester. Since psychosocial benefits provided by community garden participation nurtures various forms of resilience along individual, group and community dimensions, our research inquiry seeks to understand how dimensions of resilience vary along intersectional lines. In addition to mapping the psychosocial benefits linked to community garden plot ownership, we find that examining which forms of resilience are possible in community-based agricultural projects addresses an important gap in the academic literature, which can help us propose policy-level practices that reduce various forms of health inequities connected to food and nutrition at the local level. Using a mixed-methods approach, we will examine the experiences of two food insecure communities in Rochester: current and new growers with VCGLC plots, and individuals who currently supplement their vegetable and fruit intake via their use of community food pantries Data collected will help us accomplish two things: 1. We will examine and use CBPR methods to disseminate information on the organizational practices by The Village to assist others in planning and implementing similar community-based agricultural projects in their communities. 2. Findings will give us preliminary data to implement a larger intervention that foregrounds community-based agricultural initiatives as a model to improve physical and mental health outcomes in food-insecure communities.

Authors: Prasasty Vivitri Dewi , Istyastono Enade Perdana
Published: June 2020

Structure-based virtual screening protocol to identify potent acetylcholinesterase inhibitors was retrospectively validated. The protocol could be employed to examine the potential of designed compounds as novel acetylcholinesterase inhibitors. In a research project designing short peptides as acetylcholinesterase inhibitors, peptide AEYTR emerged as one of the potential inhibitors. This article presents the design of AEYTR assisted by the validated protocol and guided by literature reviews followed by molecular dynamics studies to examine the interactions of the pentapeptide in the binding pocket of the acetylcholinesterase enzyme. The molecular dynamics simulations were performed using YASARA Structure in Google Cloud Platform. The peptide AEYTR was identified in silico as a potent acetylcholinesterase inhibitor with the average free energy of binding (DG) of -19.138 kcal/mol.

The complex containing Ni(II)-2,2’-bipyridin (bipy)-trifluoroacetate (TFA) was prepared by direct interaction of the corresponding precursors in an aqueous solution. AAS measurement for metal content, TGA-DTA analysis and electrical conductance suggest the ionic complex of [Ni(bipy)3](CF3COO)2·6H2O. The magnetic moment of 3.13–3.17 BM indicates the paramagnetism corresponding to two unpaired electrons which is clearly higher than that of the spin only value (2.87 BM), and commonly observed due to the spin-orbit coupling in Ni(II). UV-Vis spectral property revealed the first two main ligand field bands centered at about 14200 and 18650 cm–1, which are attributed to the spin-allowed transition, 3A2g→3T2g and 3A2g→3T1g(F), respectively. The expected third band at higher energy seems to appear as a shoulder at 26500 cm–1 (378 nm), as it is masked by a strong intensity of charge transfer band centered at 31050 cm–1. The infrared spectrum exhibits mode of vibrations of the functional groups of ligand and TFA. The powder diffractogram was refined by Le Bail method and found fit as monoclinic system of space group of P21/M, with figures of merit: Rp = 3.62, Rwp = 5.76, Rexp = 3.48, goodness of fitting (GOF) 2.745 and the derived Bragg R-Factor = 0.05.

Authors: Abdulnabi Zuhair Ali
Published: June 2020

The concentration of free and total cyanide in waters was measured by using the colorimetric method through complex formation with pyridine-barbituric acid at the wavelength of 578 nm. Ten stations were selected from water surfaces in the south of Iraq. The samples were distributed among two stations, one was on Euphrates River and the other was on Tigris River (before their confluence and formatting of Shatt Al-Arab) and selected seven stations along Shatt Al-Arab River. All the samples were collected from surface water at depth of 10–15 cm and their pH was adjusted to 12 by using sodium hydroxide. The results showed the highest concentration of free cyanide (0.254 mg/L) in station W7 and the lowest concentration in stations W2, W9 and W10, while the highest and lowest concentration of total cyanide (9.962, 0.207 mg/L) were recorded in station W7 and W1 respectively. The standard deviation of all sites (n = 3) of free and total cyanide was calculated and showed 0.007–0.048 and 0.001–0.042 ranges respectively. Furthermore, some of the physico-chemical properties of water were recorded in these stations.

Pentaerythritol tetraoleate esters synthesized from high oleic palm oil methyl ester (POME) have potential as biolubricant base stock. In the present study, the chemical transesterification of POME and pentaerythritol (PE) using sodium methoxide as a catalyst was conducted under vacuum. The effect of operating variables such as reaction temperature, catalyst concentration, the molar ratio of POME to PE, vacuum pressure, and stirring rate on the yield of PE tetraoleate was examined. The ideal conditions for the reaction were at a temperature of 160 °C, 1.25% (w/w) catalyst concentration, the molar ratio of POME to PE at 4.5:1, vacuum pressure at 10 mbar, and stirring speed at 900 rpm. PE tetraoleate with a yield of 36% (w/w), was successfully synthesized under this condition within 2 h of reaction time.

Published: June 2020

In this study, we successfully developed gold nanoparticles capped with histidine (His-AuNPs) for Hg2+ detection using trisodium citrate as the reducing agent. The optimum pH for the detection of Hg2+ by His-AuNPs was 12. The addition of Hg2+ to the His-AuNPs caused the color change from red to black-blue, which is readily detectable by the naked eye. This color change is followed by a decrease in the intensity of the primary Surface Plasmon Resonance (SPR) peak at a wavelength (λ) of 525 nm and an increase in the secondary peak at λ = 650 nm. His-AuNPs effectively detected Hg2+ with limits of detection and quantitation of 1.77 µM and 5.89 µM, respectively. His-AuNPs exhibited good performance for the detection of Hg2+ in waste water collected from a steel industrial facility in Banten Province, with a recovery and a percent relative standard deviation of 115% and 1.02%, respectively.

Published: June 2020

Pada makalah ini, teknik untuk meningkatkan lebar pita pada antena Substrate Integrated Waveguide (SIW) dilakukan dengan menggunakan Defected Ground Structure (DGS) dengan cara memodifikasi bentuk dan ukuran slot tertentu pada bagian ground plane. Kombinasi antara slot split ring berbentuk persegi panjang dan slot berbentuk silang (X) sebagai DGS ditambahkan untuk mendapatkan karakteristik antena pita lebar. Substrat yang tipis dapat meningkatkan faktor kualitas (Q) yang berakibat pada sempitnya lebar pita antena. Untuk mengatasi hal tersebut, antena SIW disimulasikan dengan menggunakan substrat dielektrik yang tebal. Dimensi total antena SIW adalah sebesar 171 mm × 160,5 mm dengan ketebalan 4,905 mm dan beroperasi pada frekuensi tengah 2 GHz. Antena SIW dicatu menggunakan teknik proximity coupling yang dihubungkan dengan konektor berimpedans 50 Ω. Hasil simulasi menunjukkan bahwa lebar pita sebesar 575 MHz diperoleh antena dengan teknik yang diusulkan, dengan lebar pita -10 dB dari rentang frekuensi 1,675 GHz - 2,25 GHz, gain maksimum sebesar 6,03 dBi pada frekuensi 1,85 GHz, dan pola radiasi bidirectional.

Dalam interaksi perilaku sosial, suara manusia menjadi salah satu saluran utama pembawa atribut ekspresi emosi kondisi mentalnya. Suara manusia merupakan hasil olah vokal yang tersusun dengan disertai urutan kata demi kata, hingga menghasilkan kalimat dalam rupa pola wicara yang memiliki makna ekspresi kondisi psikologisnya. Pola tersebut memberikan karakteristik khusus untuk proses identifikasi biometrik yang menggunakan pola wicara. Teknik visualisasi berupa citra spektrum telah terbukti mampu memberikan representasi hasil olah sinyal wicara. Makalah ini mengidentifikasi jenis emosi pada wicara menggunakan kombinasi fitur multi spektrum Hilbert dan cochleagram. Spektrum Hilbert merepresentasikan hasil transformasi Hilbert-Huang (HHT) untuk memproses sinyal emosi wicara yang nonlinear dan nonstasioner secara instan dengan fungsi mode intrinsik. Dengan meniru cara kerja komponen telinga luar dan tengah, sinyal emosi wicara dipecah menjadi frekuensi yang berbeda secara alami dengan hasil representasinya berupa cochleagram. Kedua masukan berupa spektrum wicara diproses menggunakan metode Convolutional Neural Networks (CNN) yang dikenal terbaik dalam mengenali data citra karena merepresentasikan mekanisme kerja retina manusia, serta metode Long Short-Term Memory (LSTM). Berdasarkan hasil uji coba dengan tiga himpunan data (dataset) publik emosi wicara yang terbagi ke dalam delapan kelas emosi, diperoleh akurasi sebesar 90,97% dengan CNN dan 80,62% dengan LSTM.
