Unraveling the Link Between Environment and Economic Growth in Türkiye
Authors: MASANNEH Fatty , AĞAN Büşra
Published: February 2024

This study examines the short and long-run and causative interconnections between carbon dioxide (CO2) emissions, economic growth, energy use, and industrialization in Türkiye using yearly data from 1971 to 2021. The paper employs the cointegration autoregressive distributed lag (ARDL) model, which indicates the presence of a long-run nexus between the variables and the estimated long-run coefficient of economic growth, energy use, and industrialization exhibit a sensitivity of -0.726, 0.563, and 0.548 changes in CO2 emissions respectively. The error-correction term is -0.563 and significant at a 1% significance level under the cointegration-ARDL model, suggesting that the deviations from the long-run equilibrium between the variables will be addressed through correction by almost 56.3% yearly. In other words, the speed of adjustment coefficients indicates that when disequilibrium occurs, adjustments returning to equilibrium take almost two years. The Toda and Yamamoto (1995) causality test indicates a unidirectional causal link from industrialization to CO2 emissions. This finding implies that industrialization harms environmental quality in Türkiye; therefore, Türkiye must prioritize sustainable industrial development and embrace green technologies.

Authors: ÖZTORNACI Engin
Published: February 2024

Genç nüfusta yaşanan işsizlik sorunu sadece ekonomik değil sosyo-kültürel neticeleri de beraberinde taşıyan bir olgudur. Gençlerin yaşadığı işsizlik hem ekonomik büyümeyi hem de sosyal yapıyı tehlikeye sokma potansiyeli barındırdığından giderek daha fazla tartışılan bir konudur. Hem gelişmiş hem gelişmekte olan ülkeler bakımından gençlerin istihdam edilebilmesini sağlayacak kuralları koyan ve uygulayan kamu otoritesinin bu konudaki düzenleme ve denetleme görevleri daha da önem kazanmaktadır. Soğuk Savaş sonrasında yaşanan ekonomik dönüşüm ve değişimler istihdam yapısını ve mesleki yeterlilikleri de etkilemiş çok sayıda yeni iş alanları yaratmıştır. Özellikle teknolojinin değişim hızının artmasıyla iş yapış ve istihdam modelleri farklı bir yöne evrilmiştir. 2020’deki küresel pandemi, öncesinde oldukça kısıtlı gruplarda ve sınırlı sektörlerde uygulama alanı bulunan farklı çalışma modellerinin yaygınlaşmasını süratlendirmiştir. İnternetin hayatın vazgeçilmez olguları arasında yerini almasıyla hem sosyal hem de ekonomik hayatta fiziksel bağlılıktan kopmak mümkün hale gelmiştir. Bu durum özellikle nitelikli işgücünün dijitalleşmenin nimetlerin faydalanabilmesinin yolunu açarken beceri ve eğitim düzeyi düşük genç nüfusun iş bulma olanaklarını kısıtlayıcı sonuçları da beraberinde getirmektedir. Genç işsizliği sorunu ile dijitalleşme ilişkisinin değerlendirilmesi, genç nüfusun gelecekteki ekonomik potansiyelinin artırılmasına yardımcı olabileceği gibi, sosyal adaletin sağlanmasına da katkı sağlayabilecektir. Bu çalışmada genç işsizliği ile dijitalleşme kavramlarının ilişkisi açıklanarak dijitalleşmenin genç işsizliğini azaltma potansiyeli değerlendirilecektir.

Hotel enterprises in Nizhny Novgorod in 1918-1939.
Authors: Ryabova Ol'ga Vyacheslavovna , Zykova Tat'yana Valentinovna , Kochkurova Elena Adol'fovna
Published: February 2024

The market reforms that began in the late Soviet period and continued after the collapse of the USSR radically changed the country's hotel industry. The changes have affected literally all aspects of the industry. Similar large-scale changes were already taking place in the hospitality industry at the beginning of the twentieth century, after the socialist revolution of 1917. Therefore, it is interesting to find out how the young Soviet state, in the most difficult conditions of the civil war and foreign intervention, was able to practically rebuild the country's hotel industry. Because of this, the experience of hotel construction in the first two decades of Soviet power can be useful. The subject of the research in this article was the development of hotel enterprises in Nizhny Novgorod, such as communal hotels, "Peasant Houses", night shelters during this period.  The paper provides an analysis of the main directions of development of the Nizhny Novgorod hotel industry from 1918 to 1939. The article is based on materials from regional archives (TSANO and GOP NO), periodicals, and scientific literature. The article uses historical-systemic and historical-comparative methods, as well as general scientific methods such as description and comparison. The conducted research showed that the hotel industry of the city was in a difficult situation by 1918. The change in the social system in the state, the decline in the standard of living of the population, and the refugees provoked a crisis in the hotel industry of Nizhny Novgorod. The mass closure of enterprises was avoided only by nationalization and municipalization of enterprises. The opening of the Peasant's House in 1925 was able to alleviate the acute shortage of hotel stock for a short period. But in the 1930s, due to the growth of foreign tourism, the problem of a shortage of high-class hotels worsened. The construction of the Volna, Rossiya and Intourist hotels partially solved this problem. But for ordinary Soviet citizens, hotels are still inaccessible. At the same time, the level of service was at an extremely low level.
EPCMSDB: Design of an ensemble predictive control model for solar PV MPPT deployments via dual bioinspired optimizations
Authors: Hole Shreyas Rajendra , Das Goswami Agam
Published: February 2024

With the increasing demand for renewable energy, solar power has emerged as a promising option for sustainable power generation. However, the effectiveness and efficiency of solar power systems rely on the ability to effectively manage their performance, making it essential to develop efficient control models. This paper proposes a novel ensemble predictive control model for solar deployments using bio-inspired optimizations to improve load-connected solar deployments’ performance. The proposed model integrates multiple control devices, including Maximum Power Point Tracker, Proportional-Integral-Derivative, Proportional-Integral, and Fuzzy Logic Controllers, to selectively control the solar Photovoltaic systems. The proposed model incorporates a predictive control operation utilizing an LSTM-GRU (Long Short-Term Memory-Gated Recurrent Unit) with the VARMA (Vector Auto-Regressive Moving Average) model, which can accurately predict the future power generation of the solar system. This feature can facilitate efficient energy management and increase the system’s performance for different use cases. Implement a SEPIC (Single Ended Primary Inductor Capacitor) converter design to improve the system’s overall efficiency levels. To validate the effectiveness of the proposed approach, the author conducted experiments using real-world data and compared the proposed results with other control strategies. The results demonstrate that the ensemble predictive control model based on bio-inspired optimizations outperforms the existing control models regarding accuracy, efficiency, and stability levels. The proposed model has the potential to significantly improve the performance of load-connected solar deployments, offering a more practical approach to solar power generation. The combination of predictive control operations with bio-inspired optimizations can facilitate the design of sustainable energy systems with higher efficiency and accuracy.
Keindahan Saja’ Dalam Matan Tuḥfah Al-Aṭfāl Karya Sulaimān Al-Jamzūrī
Authors: Qotrunnada Zahrotul , Abdil Ghany Sayyed Zuhdi , Suryaningsih Iin
Published: February 2024

The Arabic language serves as a global communication tool and is the principal language for 2 billion Muslims across the globe. Within Arabic, there are diverse realms of discourse and academic pursuits. One such domain is the Science of Badīʿ, a branch of Balāghah (rhetoric). A key area within the Science of Badīʿ delves into the resemblance of the final letters of two words at the conclusion of Arabic sentence structures. This resemblance, termed "sajaʿ," enhances the elegance of pronunciation, a pivotal facet of Balāghah. This research endeavors to explore this aesthetic dimension within the text of Tuḥfah Al-Aṭfāl, authored by Imam Sulaimān Al-Jamzūrī, a foundational work in Tajwid, the science of Quranic recitation. Employing a qualitative methodology with a descriptive-analytical approach, this study utilizes the Badīʿ theory as an analytical framework. The findings of this research reveal that the text of Tuḥfah Al-Aṭfāl embodies the grace of sajaʿ, which manifests in three distinct categories: muṭarraf, muraṣṣaʿ, and mutawāzī. This aesthetic quality proves invaluable for both students and educators, aiding in the memorization and comprehension of Tuḥfah Al-Aṭfāl within an educational context. Furthermore, it enriches the experience for general readers, allowing them to appreciate the beauty of its expression. Despite these insights, further research is essential to explore other dimensions of beauty present in Tuḥfah Al-Aṭfāl beyond sajaʿ. Additionally, investigating the element of sajaʿ beauty in various Arabic literary works would provide a more comprehensive understanding of its significance.

According to the World Health Organization, an estimated 800,000 individuals succumb to suicide annually, translating to one person every 40 seconds [1]. The ramifications of suicide are profound, extending beyond the individual to touch families, friends, and communities, leaving behind enduring psychological, social, and economic impacts.
Deuterium Labeling of Isoaspartic and Isoglutamic Acids for Mass Spectrometry Analysis
Authors: MIYAGI MASARU , Kiesel Evan , Neumbo Kelao , Nakazawa Takashi
Published: February 2024

Isoaspartic acid (isoAsp) is a common protein modification that spontaneously arises from asparagine or aspartic acid, and it has been linked to various diseases and health conditions. However, current methods for identifying isoAsp sites in proteins often suffer from ambiguity and have not gained widespread adoption. We have developed a novel method that exclusively labels isoAsp with deuterium. This method capitalizes on the unique structural characteristics of isoAsp residues, which possess a free α-carboxyl group and can form an oxazolone ring. Once the oxazolone ring forms, it facilitates racemization at the Cα-position, incorporating a deuteron from a D2O solvent. The sites of deuterium-incorporated isoAsp in proteins can be unequivocally determined by comparing the precursor and product ion masses of the peptides from proteins reacted in H2O and D2O. The effectiveness of this method has been demonstrated through its application to model proteins, lysozyme and rituximab. Furthermore, we have confirmed that the isoAsp deuterium labeling reaction efficiently labels both L- and D-isoAsp without distinction, as well as isoglutamic acid (isoGlu), for which no effective detection methods currently exist.

The transformation of pyridines into benzene derivatives is described, using a one-pot ANRORC process with soft nucleophiles such as malonate. Triflic anhydride activates the pyridine to ANRORC synthesis of a carbocyclic β-aminoester intermediate, which aromatizes on heating. The reaction has been exemplified with a room temperature protocol, along with direct syntheses of biologi-cally active, tertiary-alkylated and isotopically-labelled benzoates.
Epigenomic states contribute to coordinated allelic transcriptional bursting in iPSC reprogramming
Authors: Ayyamperumal Parichitran , Naik Hemant Chandru , Naskar Amlan Jyoti , Bammidi Lakshmi Sowjanya , Gayen Srimonta
Published: February 2024

Two alleles of a gene can be transcribed independently or coordinatedly, which can lead to temporal expression heterogeneity with potentially distinct impacts on cell fate. Here, we profiled genome-wide allelic transcriptional burst kinetics during the reprogramming of MEF to induced pluripotent stem cells. We show that the degree of coordination of allelic bursting differs among genes, and alleles of many reprogramming-related genes burst in a highly coordinated fashion. Notably, we show that the chromatin accessibility of the two alleles of highly coordinated genes is similar, unlike the semi-coordinated or independent genes, suggesting the degree of coordination of allelic bursting is linked to allelic chromatin accessibility. Consistently, we show that many transcription factors have differential binding affinity between alleles of semi-coordinated or independent genes. We show that highly coordinated genes are enriched with chromatin accessibility regulators such as H3K4me3, H3K4me1, H3K36me3, H3K27ac, histone variant H3.3, and BRD4. Finally, we demonstrate that enhancer elements are highly enriched in highly coordinated genes. Our study demonstrates that epigenomic states contribute to coordinated allelic bursting to fine-tune gene expression during induced pluripotent stem cell reprogramming.
Knockout of PA200 improves proteasomal degradation and myelination in a proteotoxic neuropathy
Authors: VerPlank Jordan JS , Gawron Joseph M , Silvestri Nicholas J , Wrabetz Lawrence , Feltri Maria Laura
Published: February 2024

The cellular response to a decrease in protein degradation by 26S proteasomes in chronic diseases is poorly understood. Pharmacological inhibition of proteasomes increases the expression of proteasome subunits and Proteasome Activator 200 (PA200), an alternative proteasome activator. In the S63del mouse model of the peripheral neuropathy Charcot Marie Tooth 1B (CMT1B), proteasomal protein degradation is decreased and proteasome gene expression is increased. Here, we show an increase in PA200 and PA200-bound proteasomes in the peripheral nerves of S63del mice. To test genetically whether the upregulation of PA200 was compensatory, we generated S63del//PA200−/− mice. Unexpectedly, in the sciatic nerves of these mice, there was greater proteasomal protein degradation than in S63del, less polyubiquitinated proteins and markers of the unfolded protein response, and a greater amount of assembled, active 26S proteasomes. These changes were not seen in PA200−/− controls and were therefore specific to the neuropathy. Furthermore, in S63del//PA200−/− mice, myelin thickness and nerve conduction were restored to WT levels. Thus, the upregulation of PA200 is maladaptive in S63del mice and its genetic ablation prevented neuropathy.
ОСОБЛИВОСТІ ВИРАЖЕННЯ ОСНОВНОЇ ФОРМИ (ПОЗИТИВНА ФОРМА), ЩО ВИСТУПАЄ ЯК БАЗОВИЙ КОМПОНЕНТ ПОЛЯ ПОРІВНЯЛЬНИХ ПРИКМЕТНИКІВ У НІМЕЦЬКІЙ ТА АЗЕРБАЙДЖАНСЬКІЙ МОВАХ

У статті розглядаються особливості вираження основної форми (позитивна форма), яка виступає базовим компонентом поля порівняльних прикметників у німецькій та азербайджанській мовах. Аналізуються характеристики ступеня прикметників у двох різносистемних мовах. Наочно наведено приклади з матеріалів азербайджанської та німецької мов. Зміна прикметників за ступенями – це явище, пов’язане з тим, до якої групи семантичних ознак вони відносяться (якісні, відносні, присвійні). Ця властивість в основному відноситься до прикметників, що позначають якість. Прикметники звичайного ступеня не виражають відношення предмета до інших предметів, але відіграють вирішальну роль у визначенні інших ступенів як основного компонента області компаративізму. Саме на основі цієї основної форми прикметника, прийнятої як норма, пояснюються інші особливості ознаки та якості, що виражається прикметником. Таким чином, як у німецькій, так і в азербайджанській мовах ця форма прикметника виступає як основна конститутивна в області компаративізму. Наявність цієї форми забезпечує існування інших форм ступеня. В азербайджанській та німецькій мовах ступені порівняння прикметників створюються синтетичними та аналітичними методами, але вони не використовуються у вираженні звичайної форми. У даному випадку ознака і якість виражаються через саме прикметник. Точніше, атрибут і якість, властиві предмету та явищу, абстрактно виражаються в значенні прикметника. Якщо область порівнянності прикметників є макрополем в цілому, то саме це поле відображає синтез двох мікрополів. Якщо перше з них – мікрополе, що позначає рівність, то друге – поле, пов’язане з нерівністю. Позитивний ступінь, прийнятий як початковий ступінь прикметника, є виразом першого мікрополя – поля рівності.

Conclui-se que o Poder Judiciário tem papel fundamental na manutenção e garantia de direitos no Estado Democrático de Direito.
ASSISTÊNCIA SOCIAL, BIOPOLÍTICA E NEOLIBERALISMO
Authors: Rebelo Romário Edson da Silva , Yves Deluchey Jean François
Published: February 2024

A entrega de cestas básicas durante os primeiros meses da pandemia foi um verdadeiro espetáculo no Brasil, e na periferia de Belém do Pará, não foi diferente. Esse espetáculo remeteu na nossa avaliação ao papel biopolítico que a assistência social exerce. Devemos interrogar o motivo de o Estado, na atual fase do capital, financiar uma política pública voltada para famílias na linha e abaixo da linha da pobreza, famílias essas que, muitas vezes, são o alvo do extermínio legitimado pela mídia e por vozes tirando sua autoridade do Estado. Para tanto, propusemos pensá-la a partir da consolidação da assistência social no Brasil, uma história que se confunde com a caridade, o damismo e a filantropia, e assim, problematizar a gestão da miséria dentro de uma agenda neoliberal. Com isso, chegamos à conclusão de que a assistência social opera uma invasão pacífica de espaços heterotópicos com o objetivo de capturar as formas de vidas estranhas ao mercado e submetê-la a uma lógica hierarquizante.

This study investigates how digital entrepreneurship can be engaged to engender sustainable development in Nigeria. The study, premised on the Uses and Gratifications theory and Technology Acceptance model, employed the qualitative design with in-depth interview as the instrument to sample the opinions of 30 respondents on the level of adaptation of digital technology by SMEs in the Federal Capital Territory (FCT) and the influence of digital entrepreneurship on sustainable development in Nigeria. The study found that SMEs in the FCT actively espouse digital technologies to the operations of their businesses and that the adaptation of digital technologies by SMEs in the FCT have grown from 30 percent in the last three years to about 70 percent in 2023. Another important finding is that the use of digital technology has high prospects to significantly contribute to the attainment of long-term goals of entrepreneurs desirous of creating social and environmental value through innovative business models. Empirical evidence from this study points to the efficacy of digital entrepreneurship as the driving force behind the rise, growth and sustenance of SMEs, the engine of development of any nation. This study therefore concludes that digital entrepreneurship is a viable option for engendering sustainable development in Nigeria. The study recommends that given the importance and potentials of digital technologies to sustainable national development, government at national and sub-national levels should create the enabling environment through the provision of functional and accessible infrastructure necessary for SMEs to easily adopt digital technologies in the running of their businesses

Affordability of apartment design began with incorporation of flexibility attributes into the apartment design to accommodate the biosocial life of the urban dwellers. There was no evidence that the connectivity between apartment affordability and apartment design flexibility had been explored in the study area. This study aimed to investigate the apartment design flexibility in relation to apartment affordability in government-built estates in Lagos, Nigeria. A purposive case study of three estates was adopted. Structured survey methods were employed for data collection. 10% of sample population was used as sample size which amounted to 270 units. Systematic random sampling of apartment was employed. The data were analysed using descriptive statistics. The major finding revealed that partitionability had highest significant influence on affordability of apartment in the study area. Dolphin II and Odonla Estates had higher affordability of the partitionability design of the apartment. Odonla and Amuwo-Odofin Estates had higher affordability of the extendibility design of the apartment. Odonla Estate had the highest affordability of the expandability design of the housing units. The study discovered the usage of apartment design flexibility as an indicator of measuring apartment affordability. There is opportunity in this area of research to be explored in future. The will assist the stakeholders in the built environment to improve on the conceptualisation of apartment design. The study affirms that the partitionability attribute of flexibility design could be incorporated into design-based affordability of apartment at point of creation.

Public Private Dialogue (PPD) is an institutional arrangement that engages the public and private sector in discussions to resolve issues. These dialogue sessions may last for a few hours or continue for several months or years until an inclusive policy is formulated. This study focused on public-private dialogue in housing policy formulation in Lagos State. It explored how PPD can create increased housing delivery through innovative changes in policy formulation. Studies show that proactive public and private sector engagements create better opportunities for housing policy formulation. The government should intensify efforts and create opportunities for private participation in discussions through town hall meetings and dialogue sessions to formulate workable housing policies and reforms that will help actualize the housing needs of the citizens. The study employed selective sampling. Data was obtained through administered questionnaires on a population of 150 household heads in IKorodu on how involved they were in formulating Lagos State government housing policies. The data collected was analyzed using descriptive statistics. The results show that State housing policies were designed through public sector initiatives with little or no input from the private sector. The study further revealed that institutions that adopt the PPD approach in their engagements and operations have higher staff motivation and increased productivity

Authors: Kim Hyun-Jin , Nam Sang-Wook , Oh Jung-Suek
Published: February 2024

This paper presents a compact 1:3 power divider and a base station subarray antenna with enhanced polarization purity exhibiting high cross-polarization discrimination (XPD) and high input port isolation. The compact 1:3 power divider incorporating a 180° shifted path is proposed to achieve both polarization purity and the wideband characteristics of the subarray antenna, which is difficult to implement using the conventional dual-feed method in limited areas. Using the proposed power divider, a dual-polarized quadruple Π-probe feed stacked patch antenna array is designed, which achieves a wide bandwidth of over 30% (< -13 dB) from 1.68 GHz to 2.25 GHz. The XPD is increased by approximately 8 dB and 5 dB at 1.71 GHz and 2.11 GHz, respectively, to attain an increase in the isolation bandwidth (< -20 dB) from 14% to 43%. Furthermore, the measurement results of a 4 × 3 antenna array confirm the effectiveness of the proposed design in terms of XPD and isolation while maintaining the bandwidth and beam performance. This study demonstrates a relatively wide bandwidth between patch antennas, despite the use of multiple subarrays. The comparative results also show a relatively better frontto-back ratio and isolation of the proposed design.

This paper proposes a novel packaging and large-scale antenna-assembled structure for a printed circuit board (PCB) that reinforces productivity, facilitates cost reduction, and maintains reliability. This was achieved by splitting the antenna from the main board and packaging it into a radio-frequency integrated circuit. In addition, two innovative solutions—an externally attachable flexible PCB antenna and a PCB-embedded coaxial line—are introduced to overcome the degradation in antenna performance and vertical RF transition loss in the proposed low-cost hybrid PCB. First, the proposed externally attachable flexible PCB antenna and a parasitic aircoupled antenna, which were easily assembled on the PCB, achieved an antenna efficiency of 95% and an impedance bandwidth of 7 GHz. Second, the fabricated coaxial line exhibited enhanced impedance matching over a wide frequency range of 30–40 GHz and improved insertion loss of approximately 1.4 dB. Furthermore, the packaged antenna, composed of 256 dual-polarized antenna elements per stream, incorporated a 39 GHz CMOS-based 16-channel phased-array transceiver IC. The set-level beam-forming measurements were verified considering an effective isotropic radiated power of 55 dBm at boresight and a steering range >±60°. In addition to being suitable for mass production in terms of cost and reliability, the proposed structures and solutions met the required antenna and beam-forming performance for commercial 39 GHz base stations without sacrificing performance.
Computation of TM Scattered Fields Induced by a Truncated Semi-Elliptic Cavity in a PEC
Authors: Bozorgi Mehdi
Published: February 2024

This study investigated the scattered transverse-magnetic (TM) electromagnetic field from a truncated semi-elliptic embedded in a perfectly electric conducting plane. Boundary value analysis and the region-point-matching technique are employed to address the issues considered. The analyzed region is divided into three sub-regions, after which the tangential fields are expanded in terms of Mathieu functions into two different coordinate systems. By applying boundary conditions at two auxiliary boundaries and using the region-pointmatching technique, several independent equations are constructed and subsequently simplified to generate a system of linear equations. For the validation of the obtained results, the suggested procedure is compared to the method of moment. Finally, the effects of cavity depth and incident angle on the scattering signature are inspected.
Detection of Fall Risk Behaviors in Patients with Severe Mobility Issues Using FMCW Radar: Sitting Up and Sitting on the Side of the Bed
Authors: Yoon Hyunsoo , Shin Hyun-Chool
Published: February 2024

This study aimed to detect fall risk behaviors using radar—a non-contact sensor—to prevent falling accidents, which are one of the most fatal problems faced by older adults. Hospitals and nursing homes often have patients who cannot move alone without caregivers. In this context, the process of a patient sitting up from a lying-down position shortly before standing up has been observed as a fall risk behavior. This study added movement information as a new characteristic feature to the range and velocity information used in conventional radarbased behavior recognition studies. Performance comparisons confirmed that the addition of movement information performs excellently in detecting risk situations. Furthermore, a bidirectional long short-term memory model was trained using a feature to predict risk situations. The model exhibited accuracy, recall, and precision rates of 93.84%, 88.57%, and 99.07%, respectively. Additionally, its performance in detecting fall risk behavior was verified by conducting experiments involving continuous behaviors.
Fall Detection Using FMCW Radar to Reduce Detection Errors for the Elderly
Authors: Baik Jae-Young , Shin Hyun-Chool
Published: February 2024

Fall accidents pose a significant threat of severe injuries for the elderly, who often need immediate assistance when they fall. Since the use of conventional contact sensors or cameras might be uncomfortable for the user, research on fall detection using non-contact sensors has received considerable attention. While most prior studies have relied heavily on Doppler-based velocity parameters to detect falls, using only Doppler information may lead to erroneous detection of fall-like behavior. As a result, a feature that accounts for additional information is necessary. Addressing this need, this study developed an algorithm for classifying falls by detecting human motions using frequency modulation continuous wave radar, proposing a novel feature to reduce detection errors. The suggested feature was computed using the rangevelocity map of the 2D Fourier transform and evaluated using supervised machine learning techniques, such as support vector machine and linear discriminant analysis, attaining an accuracy higher than 91%.
A Compact MIMO Antenna Design Using the Wideband Ground-Radiation Technique for 5G Terminals
Authors: Li Rui , Qu Longyue , Kim Hyeongdong
Published: February 2024

This paper introduces a 4 × 4 multiple-input and multiple-output (MIMO) antenna application based on the conception of the characteristic mode of 5G terminals. The proposed antenna used a series capacitor and a parallel capacitor to control input impedance matching, while the resonance frequency was controlled by employing a resonance loop capacitor. In this way, we achieved a compact miniaturization antenna that uses ground radiation for the target 5G New Radio (NR) operating bands with n48, n77, and n78 bands. The simulation and measurement data revealed that the –6 dB bandwidth of the proposed antenna was approximately 1,240 MHz (ranging from 3.14 GHz to 4.38 GHz), while the efficiency also improved from 38.7% (reference) to 49.1% (proposed) within the 3 GHz to 4.6 GHz range. Furthermore, the radiation pattern exhibited satisfactory radiation performance. Therefore, it was concluded that the proposed 4 × 4 MIMO antenna set technology has promising prospects for application in 5G communication terminals in the future.

Published: February 2024

This paper proposes a 500 MS/s 4-bit flash analog-to-digital converter (ADC) featuring a differential input voltage range of 1.2 Vpp operating at a supply voltage of 1.2 V. Although the proposed circuit utilizes a conventional flash ADC structure, its track and hold circuit, driving buffer, and preamp circuits corresponding to the analog stages are designed using complementary architecture to attain a sufficient swing range even at a low supply voltage. Notably, the proposed structure satisfies the error requirements. The error source of the flash ADC, such as the comparator’s input referred offset, did not degrade its performance, while the use of a calibration circuit, characterized by power consumption and area burdens and increased complexity, could also be avoided. Therefore, the proposed flash ADC met the error requirements, such as the comparator’s input referred offset, without the need for calibration circuits. The chip, fabricated using the TSMC 65 nm process, covers an area of 1,160 × 950 μm2 and consumes 78 mW of power. Furthermore, its signal-to-noise and distortion ratio and spurious-free dynamic range were measured to be 23.36 dB and 30.26 dB, respectively, at a sampling frequency of 500 MHz.
