This study proposes a design of a modified-bridge circuit with a master–slave input supply mechanism for ozone-driven system applications. Because the single-source supply design is becoming the mainstream choice in the existing ozone-driven systems, the input supply reliability of the ozone-driven system is crucial. Therefore, this proposed design involves a modified-bridge circuit combined with inductors and transistors, which can be augmented with the energy storage device as a backup source to improve the reliability of the input supply for the ozone-driven system. In addition, considering that the original source directly connected to DC BUS can re-charge the energy storage device, the energy recycling operation mode is designed in this proposed system to extend the duration of the energy storage device, which improves the supply reliability of the ozone-driven system further. To validate this proposed system, both model formulation and hardware realization are assessed through different test scenarios. Experimental outcomes of these tests confirm the practicality of the proposed design.

This essay confronts two orthodoxies at the heart of the modernity debate. The first is that modernity, which supposedly originated from the West, is a sin­gle and universal historical development. The assumption therefore is that any genuine modernity elsewhere must proceed from aping the structuratlon of western modernity. The second orthodoxy challenges the first, and coalesces around the idea of multiple modernities, which do not share the historical con­tours of western modernity. Yet, these modernities supposedly take their ini­tiatives from the original source in the West. On the contrary, I will argue that these orthodoxies ignore a critical fact of global history: The concept of the modern was shaped and reshaped within a multilateral framework of confron­tations and conflicts amongst cultures and societies, which enabled each soci­ety to creatively respond and adapt itself to the changes it confronted. I will use the Yoruba concept of olaju as a conceptual foil to reconfigure the understand­ing of this multilateral modernity. With olaju, we arrive at the conclusion that both Europe and non-Europe are complicit in the formation and configuration of what it means to be modern. It is only from this premise that the foundation of multiple modernities can properly be erected. It is also from this premise that various societies can take charge of the elements of social change as well as the power and knowledge dynamics involved in it.

The background of Adébáyọ̀ Fálétí (1921 – 2017) was steeped in the Ọyọ̀ ́ Yorùbá culture. He had a princely connection to the throne of Ọyọ̀ ́ having been born by Dúrówadé Àyìnkẹ, a granddaughter of Prince Adé ́ ṣọ̀kàn, Bàbá Ìdódẹ, Aláàfin Àtìbà’s son, to Àkànbí Fálétí. Àkànbí Fálétí was a royal oral artist in the palace of Aláàfin Ṣiyanbọ́lá Oníkẹẹ̀ pé Ládìgbòlù (1911 – ́ 1944). He later practiced outside the palace, leading his own band, going about Ìlọrin and its environs and parts of Northern Yorùbáland. The late Pa David Adéníji of Ìwó, we reliably learnt, was one of his followers. Adébáyọ̀ Fálétí spent his early life in Ọyọ̀ ́ villages such as Àgbóóyè, Ọbanàǹkò and Kúrańgà (Ọlátúnji 1982a). Adébáyọ Fálétí learnt many Yorùbá tales and garnered other ̀ native wisdom from his father and other relations. Such relations include Jímọ̀ Ọládẹ̀jọ, who was adept in proverbs, and his childless aunt, an oríkì (charcterizational) poetry exponent. The western education he acquired and the Christianity he embraced were also part and parcel of his background. His primary school education was at Ọyọ̀ ́ (1939 – 1945), his secondary school education at Ìbàdàn Boys High school, Ìbàdàn, (1951 – 1955) and his University education at the University of Ìbàdàn (1965 – 1968). He took a bachelor’s degree in English with a subsidiary in French. There is no doubt that Adébáyọ̀ Fálétí would have been influenced by Yorùbá literary artists of his time, all of whom he studied in school. Among such Yorùbá literary precursors were A. K. Ajíṣafẹ, D. A. Ọbasá and D. ́ O. Fágúnwà. Adébáyọ Fálétí collected and transcribed oral poetic forms such ̀ as proverbs and oríkì following Obasá’s example before venturing into writing 110 Adedotun Ogundeji his own compositions. Though he had been writing before 1955, he did not come into the limelight until 1955, when his 719 lines long poem, “Ẹ̀dá Kò Láròpin” won the Festival of Arts award. This time may conveniently be considered the beginning of his poetic career. The poem also marked the direction which Adébáyọ̀ Fálétí’s important contributions to Yorùbá poetry was leaning. He adapted many traditional stories for his poetic compositions. There are 35 poems in the two collections of Adébáyọ̀ Fálétí’s Yorùbá poems (Ọlátúnjí 1984 b & 1984c), 13 in the first and 22 in the second. Adébáyọ̀ Fálétí’s poems, can conveniently be classified into two: the narrative and non-narrative. The narratives tell interesting stories, some of which are adapted from the Ifá corpus and other stories collected from his father, co-hunters and other sources. The non-narrative ones are made up of poetic discourses on various social and philosophical topics. There are eleven narrative poems in the two collections. The first contains ten, the second only one. It could therefore be safely concluded that the first is dedicated to narrative poems because only four of the thirteen poems in it are non-narrative. Since there is also only one narrative poem in the second, one could also assert that it is dedicated to non-narrative poems. Four of the eleven narrative poems, (‘Ẹ̀là Lọrọ̀ ’, ‘̀ Ṣàṣọrẹ’, ‘Alágbára Ilé àti Alágbára Oko’, and ‘Agbódóro ́ - gun’) are adapted from the Ifá corpus and there are strong evidences that ìjálá (Ogun poetry/hunter’s) is the original source of the story retold in ‘Adébímpé Ojẹ̀dòkun’. The poet was reported to have collected it from his father who informed him it was a true-life story (Ọlátúnjí 1982a). In our examination of the exordiums of Adébáyọ̀ Fálétí’s poems, we shall dwell more on his narrative poems than on his non-narrative poems and limit ourselves to the aforementioned two collections (Olatunji 1982b & 1982c).

This paper proposes a new method called independent component analysis–variational mode decomposition (ICA-VMD), which combines ICA and VMD. The purpose is to study the application of ICA-VMD in low signal-to-noise ratio (SNR) signal processing and data analysis. ICA is a very important method in the field of machine learning. It is an unsupervised learning algorithm that can dig out the independent factors hidden in the observation signal. The VMD method estimates each signal component by solving the frequency domain variational optimization problem, and it is very suitable for mechanical fault diagnosis. The advantage of ICA-VMD is that it requires two sensory cues to distinguish the original source from the unwanted noise. In the three cases studied here, the original source was first contaminated by white Gaussian noise. The three cases in this study are under different SNR conditions. The SNR in the first case is –6.46 dB, the SNR in the second case is –21.3728, and the SNR in the third case is –46.8177. The simulation results show that the ICA-VMD method can effectively recover the original source from the contaminated data. It is hoped that, in the future, there will be new discoveries and advances in science and technology to solve the noise interference problem through this method.

Abstract Background Advances in droplet-based single-cell RNA-sequencing (scRNA-seq) have dramatically increased throughput, allowing tens of thousands of cells to be routinely sequenced in a single experiment. In addition to cells, droplets capture cell-free “ambient” RNA predominantly caused by lysis of cells during sample preparation. Samples with high ambient RNA concentration can create challenges in accurately distinguishing cell-containing droplets and droplets containing ambient RNA. Current methods to separate these groups often retain a significant number of droplets that do not contain cells or empty droplets. Additionally, there are currently no methods available to detect droplets containing damaged cells, which comprise partially lysed cells, the original source of the ambient RNA. Results Here, we describe DropletQC, a new method that is able to detect empty droplets, damaged, and intact cells, and accurately distinguish them from one another. This approach is based on a novel quality control metric, the nuclear fraction, which quantifies for each droplet the fraction of RNA originating from unspliced, nuclear pre-mRNA. We demonstrate how DropletQC provides a powerful extension to existing computational methods for identifying empty droplets such as EmptyDrops. Conclusions We implement DropletQC as an R package, which can be easily integrated into existing single-cell analysis workflows.

Marilyn Monroe is already a mass culture personage. Andy Warhol created an image that removes us from the original source, on the basis of impressions associated with the life of a real person. The diptych has turned into a kind of template that can be easily filled with different meanings. The author of the article reflects on the characteristic features of this template, which is often used by contemporary artists to reproduce. The question of the citation of this diptych in the culture of the second half of the 20th century is quite well studied. But the experience of a specific kind of appropriation of this image by artists of the new millennium has already accumulated. Among them, the masters of thrash art are of particular interest: Vik Muniz and Jane Perkins. It is significant that they do not refer to the numerous photographic and film images of Marilyn Monroe. They refer specifically to the template created by Andy Warhol. They play with it, translating the substantive problems of this famous diptych into the plane of design.

Abstract This paper presents the results of a corpus-based analysis of a special type of modification of the English (as) Adj as NP similes. The modification involves filling the property slot with a cognate noun-adjective compound, i.e., a compound adjective consisting of the original adjective and the noun representing the original source of comparison, and inserting a new source of comparison into the construction (red as blood vs blood-red as a raw steak). Our data come from three sources: the Corpus of Contemporary American English (COCA), the iWeb Corpus, and material published on the Google website. Using quantitative methods we first explored whether there is a relationship between various distributional and formal features of the “original” as-similes and their likelihood of exhibiting this type of modification behavior. We then performed a quantitative and qualitative analysis of the semantic and, to a lesser extent, discourse-related features of authentic examples of this type of modification. Our results indicate that while these modifications are not abundant, the as-similes that have been found to modify in this way are significantly different from the as-similes that have been found not to modify in this way, on a number of formal and distributional features. The analysis of the semantic and discourse-related features of the modifications themselves revealed (i) the typical semantic domains of the three nominal entities featured in the modified simile: the original source, the new source, and the target, including the semantic fit among the domains of those entities; (ii) the typical semantic domains of the properties for which the three nominal entities are compared, including the semantic fit among the domains of those properties; and (iii) the typical text varieties accommodating these modifications. The latter results confirm, and to some extent elaborate on, some earlier findings about the semantic and discourse-related profiles of similes at large.

AbstractThe continuous rise in cancer incidence places a massive burden on the health sector to increase efforts in the fight against cancer. As a holistic complementary medicine modality, homeopathy has the potential to assist in the supportive and palliative treatment of cancer patients. Recent empirical studies demonstrate the presence of silica and original source nanoparticles in ultra-high dilutions of several homeopathic medicines. Recent studies have also demonstrated the efficacy of phototherapy in inducing the ablation of cancer cells through laser-activated nanoparticle photosensitizers. A new hypothetical research model is presented herein, in an attempt to investigate and compare the phototherapeutic effects of homeopathic source nanoparticles with photosensitizing nanoparticle agents that have previously been tested.

So called Higuchi’s method of fractal dimension estimation is widely used and the term Higuchi’s fractal dimension even occurs in many publications. This paper deals with this method from mathematical point of view. Terms distance and dimension and its basic properties are explained and Higuchi’s dimension according the original source is defined. Definition of Higuchi’s dimension was comparated with mathematical definition of the distance and dimension. It is showed, that the definition of the Higuchi’s dimension does not satisfy axioms of distance and dimension. So called Higuchi’s method and Higuchi’s dimension are mathematically incorrect. Therefore, all results achieved by this method are scientifically unreliable.
