GÖRSEL SANATLARDA NARKİSSOS MİTİ VE NARSİSTİK EĞİLİMLER BAĞLAMINDA OTOPORTRE

ÖZ

Bu çalışmanın amacı Ovidius’un Dönüşümler adlı yapıtında ele aldığı Narkissos mitini yorumlayan ressamların yapıtlarını ve narsistik kişilik özellikleri barındıran otoportreleri incelemek, sanatçıların kendilerine olan hayranlıklarının ya da bazı durumlarda psikanalitik bağlamda narsistik eğilimlerinin sanatsal üretim biçimlerine etkilerini farklı dönem ve üsluplar bağlamında göz önüne sermektir. Alberti’nin Narkissos’un ilk ressam, sudaki yansımasının ilk resim ve yansıtıcı yüzeyin de ilk sanatsal medyum olduğu yolundaki tezinden yola çıkıldığında otoportre çalışan sanatçıların yapıtlarında mitin ve söz konusu teorinin izleri açığa çıkar. Alberti’nin metaforunu ileri bir aşamaya taşırsak ilk ressamın Narkissos olduğu bir senaryoda otoportre ilk resim türü olacaktır. Narkissos’un imge ile ilişkisi kendi tasviri-yansıması üzerinden yürür; dolayısıyla otoportre çalışan ressamların üretim pratiği Narkissos’unki ile paralellik gösterir. Art kelimesinin etimolojisine baktığımızda pek çok batı dilinde olduğu gibi kökeninin yapay-artificial kavramına dayandığını görürüz. Burada kendi imgesinin peşine düşen ressam -Narkissos’un aksine- imgeyi dönüştürerek doğadaki yansımasına ve doğanın kaotik güçlerine karşı zafer kazanmış; bir anlamda Narkissos’un trajik sonunu tersine çevirmiştir. Bu çalışmada ele alınan, sanat tarihinin kültleşmiş otoportreleri ile narsisizm arasındaki bağlantılar araştırılırken patolojik boyuta varan özseverliğin olumlu bir dönüşüm geçirerek yaratıcı ifadeye katkı ve etkileri tartışılır.

Species and habitat specific changes in bird activity in an urban environment during Covid 19 lockdown
Authors: Sun Congnan , Hassin Yoel , Boonman Arjan , Shwartz Assaf , Yovel Yossi
Published: August 2023

Covid-19 lockdowns provided ecologists with a rare opportunity to examine how animals behave when humans are absent. Indeed many, sometimes contradicting, studies reported various effects of lockdowns on animal activity, especially in urban areas and other human-dominated habitats. We explored how Covid-19 lockdowns in Israel have influenced bird activity in an urban environment by using continuous acoustic recordings to monitor three common bird species that differ in their level of adaptation to the urban ecosystem: (1) the hooded crow, an urban exploiter, which depends heavily on anthropogenic resources; (2) the rose-ringed parakeet, an invasive alien species that has adapted to exploit human resources; and (3) the graceful prinia, an urban adapter, which is relatively shy of humans can be found urban habitats with shrubs and prairies. Acoustic recordings provided continuous monitoring of bird activity without an effect of the observer on the animal. We performed dense sampling of a 1.3 square km area in northern Tel-Aviv by placing 17 recorders for more than a month in different micro-habitats within this region including roads, residential areas and urban parks. We monitored both lockdown and no-lockdown periods. We portray a complex dynamic system where the activity of specific bird species decreases or increases in a habitat-dependent manner during lockdown. Specifically, urban exploiter species decreased their activity in most urban habitats during lockdown, while human adapter species increased their activity during lockdown especially in parks where humans were absent. Our results also demonstrate the value of different habitats within urban environments for animal activity, specifically highlighting the importance of urban parks. These species- and habitat-specific changes in activity might explain the contradicting results reported by others who have not performed a habitat specific analysis.
Barcode-free multiplex plasmid sequencing using Bayesian analysis and nanopore sequencing
Authors: Uematsu Masaaki , Baskin Jeremy M.
Published: August 2023

Plasmid construction is central to life science research, and sequence verification is arguably its costliest step. Long-read sequencing has emerged as a competitor to Sanger sequencing, with the principal benefit that whole plasmids can be sequenced in a single run. Nevertheless, the current cost of nanopore sequencing is still prohibitive for routine sequencing during plasmid construction. We develop a computational approach termed Simple Algorithm for Very Efficient Multiplexing of Oxford Nanopore Experiments for You (SAVEMONEY) that guides researchers to mix multiple plasmids and subsequently computationally de-mixes the resultant sequences. SAVEMONEY defines optimal mixtures in a pre-survey step, and following sequencing, executes a post-analysis workflow involving sequence classification, alignment, and consensus determination. By using Bayesian analysis with prior probability of expected plasmid construction error rate, high-confidence sequences can be obtained for each plasmid in the mixture. Plasmids differing by as little as two bases can be mixed for submission as a single sample for nanopore sequencing, and routine multiplexing of even six plasmids can still maintain high accuracy of consensus sequencing. SAVEMONEY should further democratize whole-plasmid sequencing by nanopore and related technologies, driving down the effective cost of whole-plasmid sequencing to lower than that of a single Sanger sequencing run.

La región de La Rumorosa, localizada en el noroeste de México, se caracteriza por sus fuertes velocidades en la magnitud del viento a nivel local, lo que ha originado la instalación de parques eólicos. En esta zona, no se conoce de forma precisa la contribución de energía eléctrica eólica de los vientos de Santa Ana (VSA), que son parte del régimen de viento regional. Además los vientos de valle-montaña, los frentes fríos, las tormentas extratropicales y otros fenómenos meteorológicos, en conjunto, contribuyen a la totalidad de energía eléctrica generada. Por ello, este estudio se centra en clasificar, por un periodo temporal de 10 años (2005-2014), los eventos de VSA considerando las categorías: “débil”, “moderado” y “fuerte”. En el análisis se aplicaron criterios asociados a los parámetros de la magnitud de la velocidad promedio del viento, el gradiente de presión adimensional y la normalización de valores de presión, magnitud de la velocidad de ráfaga y magnitud de la velocidad promedio del viento. La clasificación propuesta proporciona información sobre el comportamiento de los VSA en la zona y, por ende, su contribución en la generación de energía eólica en La Rumorosa.
Dual Antiplatelet Therapy After Acute Coronary Syndrome: A Constantly Evolving Strategy
Authors: Duronto Ernesto
Published: August 2023

“In cardiology, before changing treatment management, we require that the new evidence comes from many large studies involving many patients to convince us to abandon an established treatment which was based on much less evidence, or, as in this case, had been adopted because it was the established follow-up of the randomized studies of that time. This resistance to change may be caused by the prudence of waiting for more evidence (how much more?)”

Published: August 2023

Anti‐ambipolar heterojunctions are vital in constructing high‐frequency oscillators, fast switches, and multivalued logic (MVL) devices, which hold promising potential for next‐generation integrated circuit chips and telecommunication technologies. Thanks to the strategic material design and device integration, anti‐ambipolar heterojunctions have demonstrated unparalleled device and circuit performance that surpasses other semiconducting material systems. This review aims to provide a comprehensive summary of the achievements in the field of anti‐ambipolar heterojunctions. First, the fundamental operating mechanisms of anti‐ambipolar devices are discussed. After that, potential materials used in anti‐ambipolar devices are discussed with particular attention to 2D‐based, 1D‐based, and organic‐based heterojunctions. Next, the primary device applications employing anti‐ambipolar heterojunctions, including anti‐ambipolar transistors (AATs), photodetectors, frequency doublers, and synaptic devices, are summarized. Furthermore, alongside the advancements in individual devices, the practical integration of these devices at the circuit level, including topics such as MVL circuits, complex logic gates, and spiking neuron circuits, is also discussed. Lastly, the present key challenges and future research directions concerning anti‐ambipolar heterojunctions and their applications are also emphasized.
Effect of 915‐MHz low‐temperature microwave irradiation on the molecular structure of coking coal
Authors: Ge Tao , Wu Manting , Xu Jingyao , Cheng Jiezhong , Liu Dinghao , Wu Jing , Liu Song
Published: August 2023

The effect of microwave irradiation on the coking‐coal structure is important to study at the molecular scale to improve the quality of coking coal and optimize the coal‐blending technology for low‐quality coal. Through the characterization of coal structure by Fourier transform infrared spectrometer (FTIR), carbon‐13 nuclear magnetic resonance (13C‐NMR), and X‐ray photoelectron spectroscopy (XPS), the macromolecular structure unit model of coal before and after 915‐MHz microwave irradiation were constructed. A small number of alkyl side chains and cycloalkanes were broken, aromatic structures underwent condensation, and the aromatization of coal structure was increased after 915‐MHz microwave irradiation within 100–150°C. The content of hydroxyl self‐conjugated hydrogen bonds was increased, and the coal had more conjugated structures. Some phenolic hydroxyl groups and other functional groups were oxidized. The content of protonated pyridine and nitrogen oxides were increased, the content of pyridine and pyrrole nitrogen structures were decreased, and some nitrogen structures were oxidized. Mercaptan (thioether) and sulfoxide(sulfone) were partly converted into inorganic sulfur and partly converted into the more stable thiophene structure.
Role of updraft in dry‐season torrential rainfall in Greater Jakarta, Indonesia
Authors: Handayani Asteria Satyaning , Permana Theodorus , Isoda Yuzuru
Published: August 2023

Coastal urban areas in tropical regions, such as Greater Jakarta (GJ) in Indonesia, are susceptible to flood hazards from torrential rainfall. Efforts to understand the convective mechanisms leading to this type of rainfall have been carried out extensively, especially for events occurring in the wet season. However, hydrometeorological risks persist even in the dry season, when the rainfall is more closely correlated with the diurnal wind circulation. Among the aspects of convective activities and this diurnal circulation, the details of the updraft remain the least studied and open for discussion. We investigate the role of the updraft in urban torrential rainfall over GJ, using data from a C‐band Doppler radar and reanalysis dataset during the dry season of 2018–2019. Employing back‐trajectory calculations, we locate updraft origins corresponding to the peak of daytime inland rainfall. Most updraft origins are localized at an NW–SE‐oriented front nearly parallel to the coastline on the low‐lying plain, suggesting a region of atmospheric destabilization favorable for convective activity. The dry‐season torrential rainfall over GJ may involve convective activity from this front, that from earlier updrafts originating above the densely populated area, and further enhancement coming from orographic contributions. Our findings suggest the important role of updrafts in the rainfall generation, providing insights into the convective mechanism over GJ.

This article investigates the differences between the ongoing digital advancements in the market‐based society and the future market‐technology society in the Fourth Industrial Revolution. This article explores the “markets of tomorrow” that embody the production capacity limits of technological progress to respond to socio and economic transformations amid viral threats, digitalization, and sustainable growth development. Examining the digital economy and technological advancement in developed and developing countries is being conducted. Generally, three key factors play a significant role in determining business strategy and development. These are the threat of viral infections, the process of digitalization, and the need for sustainable development. Our findings show that socio‐institutional innovations are present in the current landscape and play a role in guiding suggestions for managing these markets, considering their unique characteristics. The novelty of this article is analyzing the digital divide as a new form of global asymmetry. This is particularly important when there is a growing emphasis on polarization and power relations, especially under the conditions of digital competition in new markets of tomorrow, which the Fourth Industrial Revolution has predetermined.

An efficient VLSI architecture for fast motion estimation by hybridizing parallel spiral and adaptive threshold star diamond search algorithm‐based search algorithm in HEVC
Authors: Satheeskumar R. , Raghavaiah Bonam , Geerthik S. , Senthil Kumar T.
Published: August 2023

This article proposes a high efficiency video coding (HEVC) standard hardware using block matching motion estimation algorithm. A hybrid parallel spiral and adaptive threshold star diamond search algorithm (Hyb PS‐ATSDSA) proposes for fast motion estimation in HEVC. Parallel spiral search approach utilizes spiral pattern for searching from center to the surroundings and adaptive threshold SDA consists of two phases, they are adaptive threshold and star diamond algorithm. To lower computational complexities in HEVC architecture, parallel spiral search algorithm uses several blocks matching schemes. Adaptive threshold and star diamond algorithm are used to reduce the matching errors and remove the invalid blocks early from the procedure of motion estimation and finally predicts the final motion of the image. Speed is increased while using this hybrid algorithm. Proposed structure is carried out in Xilinx; ISE 14.5 design suit, then the experimental outcomes are analyzed to existing motion estimation strategies in field‐programmable gate array devices. Experimental performance of the proposed Hyb‐PS‐ATSDSA‐ME‐HEVC method attains lower delay 33.97%, 32.97%, 62.97, and 26.97%, and lower area 34.867%, 45.97%, 27.97%, and 43.967% compared with the existing methods, such as FSA‐ME‐HEVC, TZSA‐ME‐HEVC, hyb TZSA‐IME‐HEVC, and IBMSA‐ME‐HEVC, respectively.
Vectorizing and distributing number‐theoretic transform to count Goldbach partitions on Arm‐based supercomputers
Authors: Jesus Ricardo , Oliveira e Silva Tomás , Weiland Michèle
Published: August 2023

In this article, we explore the usage of scalable vector extension (SVE) to vectorize number‐theoretic transforms (NTTs). In particular, we show that 64‐bit modular arithmetic operations, including modular multiplication, can be efficiently implemented with SVE instructions. The vectorization of NTT loops and kernels involving 64‐bit modular operations was not possible in previous Arm‐based single instruction multiple data architectures since these architectures lacked crucial instructions to efficiently implement modular multiplication. We test and evaluate our SVE implementation on the A64FX processor in an HPE Apollo 80 system. Furthermore, we implement a distributed NTT for the computation of large‐scale exact integer convolutions. We evaluate this transform on HPE Apollo 70, Cray XC50, HPE Apollo 80, and HPE Cray EX systems, where we demonstrate good scalability to thousands of cores. Finally, we describe how these methods can be utilized to count the number of Goldbach partitions of all even numbers to large limits. We present some preliminary results concerning this problem, in particular a histogram of the number of Goldbach partitions of the even numbers up to 240.
Impact of a corporate social responsibility message on consumers' sustainable behaviours and purchase intentions
Authors: Louis Didier , Lombart Cindy
Published: August 2023

This study investigates the impact of a water brand's CSR message highlighting the brand's environmental concerns on brand‐related variables (attitude towards the brand and CSR) and consumer‐related variables (consumer efforts to adopt sustainable behaviours and well‐being). A research model is proposed, and the relationships postulated are tested on 414 French consumers. The study establishes the effectiveness of this kind of CSR messaging in influencing French consumers to purchase and recommend a particular brand. It then shows the direct and indirect ways in which a brand's CSR messaging can improve consumers' behavioural intentions (i.e., intentions to purchase the brand's products and to recommend the brand and/or its products). It also underscores that brand‐related variables contribute to increasing brands', and thus companies', business performance, whereas consumer‐related variables contribute to increasing their social performance. Finally, the REBUS‐PLS method emphasises the existence of several consumer groups and identifies the core target customer groups on which companies should focus their communication efforts.

Plant genetic diversity differs in habitat's oscillations, especially species distributed under heterogeneous environmental conditions. Freshwater ecosystems are vulnerable to biotic and abiotic impacts, which affect the genetic and epigenetic variations in aquatic plants. The extent of environmental heterogeneous attributes can be examined based on genetic and epigenetic variations. Such variations under environmental gradient can provide evidence for understanding the correlations between rapid environmental changes and species evolution. In this study, we performed amplified fragment polymorphism length and methylated‐sensitive amplified polymorphism analysis to depict the genetic and epigenetic variations of Vallisneria natans in a subtropical lake. Results showed that this species maintained a relatively high genetic diversity (mean HE = 0.320, I = 0.474, PPL = 85.93%) and epigenetic variation (mean eHE = 0.282, eI = 0.428, ePPL = 83.91%). Water body temperature and chlorophyll a density were positively correlated to the genetic and epigenetic variations. The clonal generates of V. natans depicted a relative high methylation level and shew ancestral scenario between the genet and the second clonal generation. These findings revealed that species diversity is unevenly distributed under environmental heterogeneity, even at a fine geographic scale. Environmental characteristics in relation to temperature and chlorophyll a should be considered in the analysis of the genetic and epigenetic variations. Additionally, epigenetic variations between genets and ramets should be considered with caution when applied to analysis of other aquatic species.
Removal ofN‐fixing vs.non‐N‐fixing herbs in postfire chaparral: Competition and contributions to soil N and C cycling

As climate change increases fire frequency in Mediterranean‐type shrublands, it is essential to understand the links between common postfire plant assemblages and soil nitrogen (N) and carbon (C) cycling during succession. In California chaparral, periodic fire removes shrub cover, deposits ammonium (NH4+‐N) on soils, and allows herbaceous assemblages to dominate for 3–5 years. Herbs influence soil biogeochemistry through several mechanisms, including nutrient uptake, litter decomposition, and rhizodeposition. Controlled experimental removal of select plant groups from wild assemblages can demonstrate interactions between plant groups and how plant traits influence belowground processes. In a two‐year herb‐removal experiment, we investigated the impact of N‐fixing and non‐N‐fixing herbs on soil N and C cycling. Treatments were (1) all herbs, (2) only non‐N‐fixing species, (3) only N‐fixing species, and (4) no herbs. In high‐N environments, N‐fixers were predicted to compete poorly against non‐N‐fixing neighbors. N‐fixers doubled in abundance when non‐N‐fixers were removed, but non‐N‐fixers were unaffected by N‐fixer removal. Two years after fire, no‐herbs plots had the lowest soil microbial respiration rates, and total accumulated C and N were lower than all‐herb plots. Two treatments, no‐herb and N‐fixer plots, had elevated mineral N concentrations, net N mineralization, and net nitrification in the second year of the experiment. Our findings underscore the importance of fire‐following herbs for postfire N retention and organic matter accumulation. A combination of both N‐fixing and non‐N‐fixing herbs maximized total soil C and N, although the accumulation of TC and TN in all‐herb plots was not significantly higher than in non‐N‐fixer plots. Results demonstrated the key role of non‐N‐fixing herbs in accumulating soil C and herbaceous communities for retaining N. Elevated soil nutrient availability two years postfire may contribute to the long‐term recovery of shrubs, even after herbs are no longer dominant. Future investigations should also consider the magnitude of soil microbial N retention in plots with different herb functional groups, along with the species‐specific contribution of non‐N‐fixing herbs to postfire C and N cycling.
Molybdenum Tricarbonyl Complexes Supported by Linear PNP Ligands: Influence of P‐ and N‐Substituents on Relative Stability, Stereoisomerism and on the Activation of Small Molecules

Series of linear tridentate PNPhPR‐ligands (R=Me, Et, Pln, Ph, Cyp, iPr, Cy, tBu) and molybdenum tricarbonyl complexes [Mo(CO)3PNPhPR] (R=Ph, Et, Cyp, iPr, Cy,) were synthesized and characterized using NMR‐, IR‐, and Raman spectroscopy as well as X‐ray crystallography. The influence of the different phosphine donor groups of the PNPhPR ligands on the bonding and activation of CO ligands is investigated. Importantly, all complexes are found to adopt a fac geometry, both in solution and in the solid state. This is in contrast to analogous complexes supported by PNHP ligands. DFT calculations reveal that the phenyl ring at the central amine function is the cause of the preferred geometry, hindering isomerization to a mer geometry.

Introduction

Prostate biopsy is commonly performed using a transrectal ultrasound probe through a transrectal or transperineal approach. However, this is not possible for patients without a rectum.

Case presentation

A 75‐year‐old male was referred to our hospital because of an elevated prostate‐specific antigen and a suspicious prostate lesion (PIRADS 5) in the left peripheral zone. The patient had previously undergone abdominoperineal resection for rectal cancer, which excluded the use of transrectal ultrasound. We describe the use of the transperineal ultrasound‐guided biopsy with cognitive magnetic resonance imaging‐transperineal ultrasound fusion and the utility of the injection of bubbled lidocaine jelly into urethra to improve its visualization. The pathological findings revealed clinically significant cancer with a Gleason score of 5 + 4.

Conclusion

Cognitive magnetic resonance imaging‐transperineal ultrasound fusion transperineal prostate biopsy with injection of bubbled jelly into urethra is a feasible and practical technique that does not require any specialized equipment.

Our previous studies have found that the aerial part of Hyptis rhomboides and the seed of Hyptis suaveolens contain xanthine oxidase (XO) inhibitors, inspiring us to investigate the chemical constituents of H. suaveolens stem. The EtOH extract of H. suaveolens stem was fractionated by liquid‐liquid partitioning, followed by separation over Sephadex LH‐20, silica gel, and reverse‐phase column chromatography, centrifugal partition chromatography, and semi‐preparative RP‐HPLC, to give 17 bioactive isolates. Of these, dimethyl melitrate A (9) is a new natural product, 10 is likely (7″ E)‐9′‐methyl melitrate A, only caffeic acid (2) is the same as those isolated from the seed of the same plant, and only nepetoidins A (14) and B (11) are the same as those from H. rhomboides stem. Nepetoidin B (11) showed the best anti‐XO activity. Rosmarinic acid (3) is the most abundant (>661 ppm; w/w, dried stem), while melitric acid (12) (>277 ppm), caffeic acid (2; >125 ppm), and methyl rosmarinate (4; >81 ppm) are the major ones. This outcome could serve as a good basis for chemotaxonomy of the Hyptis plants and is beneficial for developing H. suaveolens stem as anti‐hyperuricemic nutraceutical.

Background

Adenoviral vectors are among the most frequently used vectors for gene therapy and cancer treatment. Most vectors are derived from human adenovirus (Ad) serotype 5 despite limited applicability caused by pre‐existing immunity and unfavorable liver tropism, whereas the other more than 100 known human serotypes remain largely unused. Here, we screened a library of human Ad types and identified Ad4 as a promising candidate vector.

Methods

Reporter‐gene‐expressing viruses representative of the natural human Ad diversity were used to transduce an array of muscle cell lines and two‐ or three‐dimensional tumor cultures. The time‐course of transgene expression was monitored by fluorescence or luminescence measurements. To generate replication‐deficient Ad4 vector genomes, successive homologous recombination was applied.

Results

Ad4, 17 and 50 transduced human cardiomyocytes more efficiently than Ad5, whereas Ad37 was found to be superior in rhabdomyocytes. Despite its moderate transduction efficiency, Ad4 showed efficient and long‐lasting gene expression in papillomavirus (HPV) positive tumor organoids. Therefore, we aimed to harness the potential of Ad4 for improved muscle transduction or oncolytic virotherapy of HPV‐positive tumors. We deleted the E1 and E3 transcription units to produce first generation Ad vectors for gene therapy. The E1‐ and E1/E3‐deleted vectors were replication‐competent in HEK293 cells stably expressing E1 but not in the other cell lines tested. Furthermore, we show that the Ad5 E1 transcription unit can complement the replication of E1‐deleted Ad4 vectors.

Conclusions

Our Ad4‐based gene therapy vector platform contributes to the development of improved Ad vectors based on non‐canonical serotypes for a broad range of applications.
