In this paper, a comparative study between performance of BJT and CMOS technologies is performed by implementing two novel BJT and CMOS differential voltage current conveyors (DVCCs) with minimum and equivalent sizes. In this study, “size” means the number of the transistors used in a design. The CMOS-DVCC consists of only 12 MOS transistors, and the BJT-DVCC includes 13 BJTs. The implementations are performed in Proteus-7 environment, and the two DVCCs are formulized with their real parameters. The two chips are modeled at low frequency, and it is shown that the CMOS-DVCC has acceptable performance and behavior to operate as a DVCC while the parameters of the BJT-DVCC are far from an ideal DVCC, so the CMOS-DVCC can be used to design electronic devices. The comparative analysis shows to achieve a reliable and acceptable BJT implementation of a DVCC, it is inevitable to increase the size of the BJT implementation. To prove this claim, another novel acceptable BJT-DVCC with larger size is presented and modeled. It is also demonstrated that the acceptable BJT-DVCC is also the first and only DVCC reported in the literature which is applicable to high-power applications, and this is the other contribution of this work.

Inductive Power

In inductive power transfer (IPT) systems, series–series (S-S) and double capacitances and inductances–series (LCCL-S) compensation topologies are widely utilized. In this study, the basic characteristics of S-S and LCCL-S are analyzed and compared in the tuning state. In addition, considering the universality of detuning, and because the two topologies have the same secondary structures, the voltage and current stress on components, input impedances, voltage gains, and output powers of S-S and LCCL-S are mainly analyzed and compared in the detuning state, which is caused by variations in the secondary compensation capacitance. To compare the efficiency of the two topologies and verify the comparative analysis, comparative experiments based on a 2.4-kW IPT experimental prototype are conducted. The comparative result shows that the S-S compensation topology is more sensitive to load variations and less sensitive to secondary compensation capacitance variations than LCCL-S. Both in the tuning and detuning states, the efficiency of the S-S topology is higher in high-power electric vehicle (EV) applications, and the efficiency of LCCL-S is higher in low-power.

This study aims to analyze differences in domestic and international disaster research trends. We first performed topic modeling on 20,477 papers published in three domestic and 12 international journals over the last 21 years (2000-2020) and then visualized the trends. Based on the extracted topics and keywords, we analyzed keyword networks using Gephi. Research in domestic journals mainly revolved around natural disasters like earthquakes, fire, and flooding. In contrast, international journals spotlighted policy-based topics such as disaster governance and community resilience. Meanwhile, globally, building and civil engineering research has shrunk in recent five years (we refer to this as a cold topic). On the other hand, in the past five years, fire and flood research has appeared more frequently in domestic journals, while international journals have presented more articles on community resilience, risk perception, and behavior (we refer to this as a hot topic). Results of this research can provide suggestions about the directions domestic disaster research should develop in the future.

This article offers a comparative study of the domestic and international dimensions of two calamitous famines in Communist countries: one in the USSR engendered by Iosif Stalin's Great Turning Point (1928–1934) and the other in the People's Republic of China in connection with Mao Zedong's Great Leap Forward (1958–1962). The article traces the historical roots of these catastrophes and explains how Sino-Soviet interactions affected the genesis of the famine in China. It also discusses the long-term consequences of these avoidable tragedies, comparing their impact on subsequent Soviet and Chinese history. A close look at the evident affinity between the famines opens new and at times unexpected vistas, which allow us not only to get a better grasp of each event in its own specificity but also to shed new light on fundamental questions.

Abstract. The Similarity of Traditions and Symbols: Comparative Study of Recent Rock Art in Indo-Malaysia. As an ancient art, rock art, in general, is always associated with the prehistoric hunter-gatherer communities in the upper Paleolithic period or about 40,000 years ago. However, it was later discovered that the tradition of drawing/painting inside the cave was still practiced by modern hunter-gatherer communities in the 19th century, especially in the Indo-Malaysian region. This article seeks to conduct a comparative study of "recent" rock art in Lenggong Region, Perak, Peninsular Malaysia with the new findings of "recent" rock art from Bukit Bulan Region, Sarolangun, Jambi, Sumatera Island, Indonesia. The method used is a comparative analysis that seeks similarities from attributes such as techniques, motifs, sizes, and characters. The results show that both recent “young” rock art in the two regions are somehow alike. Also, contextual studies show the existence of similar traditions and behavior between modern hunter-gatherer communities in both regions.   Abstrak. Gambar cadas sebagai kesenian purba pada umumnya selalu dikaitkan dengan manusia prasejarah, yakni pemburu-peramu pada masa paleolitik atas atau sekitar 40.000 tahun yang lalu. Setelah itu, belakangan telah diketahui bahwa tradisi menggambar di dalam gua masih dilakukan oleh  masyarakat pemburu-peramu modern pada abad ke-19, khususnya di wilayah Indo-Malaysia. Artikel ini dimaksudkan untuk melakukan studi perbandingan terhadap gambar cadas “muda” di Kawasan Lenggong, Perak, Semenanjung Malaysia, dengan temuan baru berupa gambar cadas “muda” di Kawasan Bukit Bulan, Sarolangun, Jambi, Pulau Sumatra, Indonesia. Metode yang digunakan adalah analisis komparatif untuk mencari kesamaan dari atribut, seperti teknik, motif, ukuran, dan karakter. Hasilnya menunjukkan bahwa banyak kesamaan atribut pada gambar cadas “muda” pada kedua situs. Selain itu, kajian kontekstual juga menunjukkan adanya tradisi dan pola perilaku yang serupa antara masyarakat pemburu-peramu modern di kedua wilayah tersebut.

This article seeks to discusses anti-corruption policies in Indonesia and Hong Kong. This research arises from the phenomenon of corruption that has become widespread in Indonesia and seems to be a never-endingproblem that has caused great damage in all sectors of life. It's not only a matter of how much the state loss or corrupt modus operandi that is even more sophisticated and even makes Indonesia one of the highest-rankingcountries in corruption cases, but it is also a matter of law enforcement whihch is less smart in handling corruption cases themselves. On the other hand, reportedly having a different approach in combating corruption, Hong Kong is considered to have been successful in carrying out its duties. With comparative study, this article will elaborate various patterns of work conducted by anti-corruption institutions in Indonesia and Hong Kong, namely the Corruption Eradication Commission (KPK) and the Independent Commission Against Corruption (ICAC).

The article provides a comparative analysis of phraselogical units with monetary component in Ukrainian, Polish and English phraseological pictures; it has been clarified that money is the subject of many sciences: economics, philosophy, psychology, sociology, etc., and it is an integral part of society, and therefore they are the part of a core value which indicates the importance of this concept. The article investigates and reveals universal and cultural-specific features of phrases with a component of money on the material of phraseological pictures of Ukrainian, Polish and English cultures. The relevance of phraseological units, sayings, proverbs, winged expressions with the money component in the modern world has been proved, because the phraseological picture better reflects the changes that are taking place in the sphere of economics, politics, culture etc., it has been found that money is associated with national self-knowledge; it has been revealed ambivalence regarding money: on the one hand, they arise as a value, and on the other, as a social evil. The most promising research is a comparative study of Slavic (Ukrainian, Byelorussian, Polish) and German (English, German) phrases to indicate people’s attitude to money.

SummarySephadex gel filtration of human plasma gave results suggesting the presence of two proactivators of plasminogen, termed proactivators A and B.Activity resembling that of proactivator A was found in rabbit plasma, but not in guinea pig plasma.Plasminogen activators produced by the interaction of proactivator A of human plasma with streptokinase had no caseinolytic or TAMe esterolytic effect.Proactivator A can be separated in a form apparently free from plasminogen, as shown by the heated fibrin plate test and by immunological analysis. On the other hand, proactivator B concentrates prepared so far are contamined with plasminogen.Human proactivators appear to be far more susceptible to streptokinase than are rabbit proactivators.Inhibitors of the fibrinolysin system were observed in the plasmas of all 3 species. These inhibitors are not present in the euglobulin fraction of plasma. Sephadex fractionation of euglobulin fractions results in proactivator preparations that do not contain inhibitors.

This is the first comparative article to investigate commonalities in Ukrainian and Irish history, identity, and politics. The article analyzes the broader Ukrainian and Irish experience with Russia/Soviet Union in the first and Britain in the second instance, as well as the regional similarities in conflicts in the Donbas region of Eastern Ukraine and the six of the nine counties of Ulster that are Northern Ireland. The similarity in the Ukrainian and Irish experiences of treatment under Russian/Soviet and British rule is starker when we take into account the large differences in the sizes of their territories, populations, and economies. The five factors that are used for this comparative study include post-colonialism and the “Other,” religion, history and memory politics, language and identities, and attitudes toward Europe.

The One

The article presents a contemporary view of the study of piyyut, demonstrating that Jewish poetry of late antiquity (in Hebrew and Aramaic) was closely related to Christian liturgical poetry (both Syriac and Greek) and Samaritan liturgy. These relations were expressed primarily by common poetic and prosodic characteristics, derived on the one hand from ancient Semitic poetry (mainly biblical poetry), and on the other from innovations of the period. The significant connections of content between the different genres of poetry reveal the importance of comparative study. Thus the poetry composed in late antiquity provides additional evidence for the lively cultural dialogue that took place at that time.
