Evaluation of the correctable decoding sequencing as a new powerful strategy for DNA sequencing
Authors: Cheng Chu , Xiao Pengfeng
Published: April 2022

Next-generation sequencing (NGS) promises to revolutionize precision medicine, but the existing sequencing technologies are limited in accuracy. To overcome this limitation, we propose the correctable decoding sequencing strategy, which is a duplex sequencing protocol with conservative theoretical error rates of 0.0009%. This rate is lower than that for Sanger sequencing. Here, we simulate the sequencing reactions by the self-developed software, and find that this approach has great potential in NGS in terms of sequence decoding, reassembly, error correction, and sequencing accuracy. Besides, this approach can be compatible with most SBS-based sequencing platforms, and also has the ability to compensate for some of the shortcomings of NGS platforms, thereby broadening its application for researchers. Hopefully, it can provide a powerful new protocol that can be used as an alternative to the existing NGS platforms, enabling accurate identification of rare mutations in a variety of applications in biology and medicine.
Firm Dynamics and SOE Transformation During China's Economic Reform
Authors: Gu Shijun , Jia Chengcheng
Published: April 2022

We study the reform of China's state-owned enterprises (SOE) with a focus on the corporatization of SOEs. We first document the empirical patterns of the "grasp the large and let go of the small" policy. To quantify the implications of the reform for aggregate output and TFP, we build a three-sector firm dynamics model featuring financial frictions and endogenous firm-type choices. Our calibrated model shows that the SOE reform can increase long-run TFP by encouraging the exit of the least efficient firms in the state sector, but the magnitude of TFP growth also depends on the efficiency in capital reallocation. In the short run, corporatization increases aggregate output and TFP because it allows the most productive SOEs to have a higher borrowing capacity than they would under privatization.

Examining the regulation of the first lineage decision in the bovine pre-implantation embryo
Authors:   , Lochhead Abbie
Published: April 2022

Early embryogenesis is the crucial stage of development that results in the distinction of cell lineages with varying developmental potentials. The first lineage decision involves the transition from totipotent cells into two tissues: the inner cell mass and the trophoblast. Knowledge of how lineage is regulated is important for the agricultural, clinical and therapeutic industries that rely on artificial reproductive technology to progress. However, our current understanding of pre-implantation embryonic development is heavily based on the mouse model. Species-specific regulation of early embryogenesis is an important consideration that has not yet been thoroughly investigated. Cattle provide an opportunity for a new model of embryonic development that will not only serve the agricultural industry but provide new insights that will help establish bovine embryonic stem cells.

In this study, I have established a timeline of protein expression during bovine embryonic development during the first 7 days in in-vitro culture. The results show that compaction and polarisation events in cattle are not only delayed compared to the mouse but asynchronous. The establishment of distinct transcription profiles is also delayed in the bovine embryo, suggesting a lack of lineage commitment at the early blastocyst stages. Contrary to the mouse, pluripotency regulator, SOX2, and trophoblast marker GATA3 are not regulated by the YAP-TEAD4 transcriptional complex in cattle, shown by manipulating YAP activity using Verteporfin and LPA. It has also been demonstrated through further functional analyses using Y27632 and Go6983 that the apical domain, responsible for regulating Hippo pathway activity in mice, is not necessary for lineage specification in cattle.

Instead, we propose that transduction of mechanical cues via YAP operates in parallel to the Hippo pathway to establish lineage-specific transcription profiles. The urgency of the mouse blastocyst to implant has meant the species have evolved ways to utilise available signaling machinery to rapidly commit cells to trophoblast lineage. Cattle, who have a much longer pre-implantation period, coordinate information from various signaling inputs to progressively establish lineage commitment. This coordination has created a functional redundancy of the Hippo pathway in the first lineage decision.

Implementation of Environmental, Social and Governance Principles in the Banking Business
Authors: Donetskova O. Yu.
Published: April 2022

At the present stage of the development of the global business community, we pay more and more attention to the principles of environmental, social and governance (ESG) responsibility. Financial intermediaries in their activities considered the influence of natural and climatic factors. Their risks sometimes turn out to be more tangible than, for example, the financial condition of customers. The subject of the study is the development of measures to implement ESG principles in banking products, and its purpose is to study implementing the above principles in Russia at the present stage of business models and setting tasks aimed at overcoming the difficulties of software in sustainable development. The research used the methods of comparative, statistical and factor analysis, identification of trends, graphical comparison, etc. The existing studies on this topic allowed us to determine the need to use ESG principles in banking business models and to identify the motives for their implementation. In the author’s conclusion, Russian banks are guides and an example of making business in line with the principles of environmental, social and governance. The speed, depth and sustainability of their application by other financial intermediaries will depend on economic incentives, government support, and the development of regulatory requirements. The transformation of the business community (according to the new rules of conduct) will bring the entire economy of the country to sustainable development. The author considers a promising topic for further study as the introduction by the mega-regulator of mandatory standards for the activities of financial intermediaries for assessing climate and environmental risks, as well as the development of a supplier audit directive on the criteria for implementing ESG principles. This determines the scientific and practical significance of the study.

Levetiracetam analogs: chemoenzymatic synthesis, absolute configuration assignment and evaluation of cholinesterase inhibitory activities
Authors: Milagre Cintia Duarte de Freitas , Do Amaral Bruno Sergio , Batista Junior Jo�o Marcos , Vilela Adriana Ferreira Lopes , Cardoso Carmen L�cia , Milagre Humberto Marcio Santos
Published: April 2022

A chemoenzymatic approach for the synthesis of ?-N-heterocyclic ethyl- and phenylacetamides, levetiracetam analogs, is described. Eight nitrile substrates were prepared through the N-alkylation of heterocycles (2-pyrrolidinone, 2-piperidinone, 2-oxopiperazine and 1-methylpiperazine) directly from hydroxyl group of ethyl and phenyl ?-hydroxynitriles with yield of 35?71% after 12 h. Twenty nitrile hydratases (NHases) were screened and showed that the N-derivatives lactam substrates led to their correspondent amides by Co-type NHase with conversion and enantiomeric excess of up to 47.5 and 52.3% for (S)-enantiomer, while the piperazine substrates underwent spontaneous decomposition by retro-Strecker reaction. In order to avoid a retro-Strecker reaction of ?-aminonitriles, ionic liquids and polyethylene glycol (PEG400) were evaluated as alternative green solvents to aqueous buffered solutions in different proportions. Temperature was another parameter investigated during reaction-medium engineering for process optimization. However, unconventional reaction media and low temperature significantly reduced the NHase activity. The absolute configuration of ?-N-heterocyclic�ethyl- and phenylacetamides, some of which were new compounds, was determined using electronic circular dichroism (ECD) spectroscopy. Additionally, their potential as cholinesterase�s inhibitors was evaluated.

Authors: BAWER Asaludin
Published: April 2022

Diğer yabancı dil öğretimi süreçlerinde olduğu gibi Türkçenin yabancı dil olarak öğretilmesi sürecinde zorlukların yaşandığı alanlardan biri, yazma becerisidir. Yazma becerisinin geliştirmesi diğer dil becerilerine göre daha zordur ve zaman almaktadır. Bu duruma alanyazında muhtelif araştırmacılar tarafından dikkat çekilmiş ve farklı öğrenici gruplarının yazma becerilerindeki hataların saptanması yapılmıştır. Ancak Türkçe öğrenme konusunda son derece istekli olan Afganistan kökenli Özbek öğrenicilerin yazma becerisi yeterli düzeyde araştırılmamıştır. Afganistan'da süregelen istikrarsız ortam ve savaş şartları bölgede araştırma yapmayı zorlaştırsa da bu ülke yabancılara Türkçe öğretimi açından önem arz etmektedir. Çünkü ülke genelinde Türkoloji bölümlerinde, özel dil kurslarında, ilk-orta ve yüksek kademeli eğitim kurumlarında hâlihazırda Türkçe öğretilmektedir. Bu makalede Türkçe öğrenen Afganistan kökenli Özbek öğrenicilerin Türkçe yazma becerisi düzeyinde karşılaştıkları sorunların belirlenmesi ve çözüm önerileri sunulması amaçlanmıştır. Çalışmanın evrenini Mezar-ı Şerif’te Belh Üniversitesinde Türkçe eğitim gören 1. sınıf Afganistan kökenli Özbek öğreniciler oluşturmaktadır. Afganistan Özbekleri açısından Türkiye Türkçesi her ne kadar ana dillerine yakınlık sebebiyle öğrenilmesi kolay bir dil gibi görünse de gerek Farsçanın gerekse de Özbekçenin etkisiyle yazılı anlatımda hedef kitle tarafından pek çok hatanın yapıldığına şahit olunmaktadır. Bu çalışma çerçevesinde söz konusu hatalar, kategoriler hâlinde analiz edilmiş çalışmanın sonunda ise bu hataları en aza indirebilmek adına bazı önerilerde bulunulmuştur.
RELATIVE SEA-LEVEL CHANGES:A SURFACE EXPRESSION OF DEEP PROCESSES
Authors:   Lomonosov Moscow State University, Chekhovich Petr
Published: April 2022

The article presents an overview of current ideas about the possible causes and physical mechanisms of relative sea-level changes. The choice of the predominant factor can be demonstrated by the study of stratigraphic sequences formed at the oceanic basin margins or in the epeiric seas of cratonic interior areas. Such studies lead to the conclusion that high frequency fluctuations with a period of less than 1 Myr are caused primarily by the glacial episodes on the land. Fluctuations with a longer period of 1-3 Myr are controlled by intraplate tectonic processes, among which the prograde metamorphism at the crust-mantle boundary is the most important. Lateral stress of lithosphere with laterally variable thickness and the dynamic topography are also possible. Tectonic processes affecting the volume of ocean basins, such as accelerating or decelerating spreading, subduction appear to be in causal relationship with the long-period sea level changes of 10 to 100 Myr and over.

Berdasarkan survei pada tahun 2018  oleh Dinas Kependudukan daerah Lombok tengah, Dusun Balemontong II memiliki 558 KK atau setara dengan 1.049 jiwa. Jumlah penduduk yang tinggi ini berbanding lurus dengan jumlah akumulasi sampah yang terus meningkat. Sampah masyarakat terutama dalam bentuk sampah rumah tangga selama ini ditumpuk begitu saja sehingga menimbulkan aroma tidak sedap dan mengganggu masyarakat. Oleh karena itu, diperlukan suatu inovasi pemanfaatan sampah rumah tangga menjadi produk yang bermanfaat seperti kompos menggunakan metode takakura. Metode Takakura pertama kali diperkenalkan oleh  Mr. Takakura pada tahun 2004. Metode takakura dipilih karena lebih efisen, ekonomis, mudah diaplikasikan oleh masyarakat dan cocok untuk pembuatan kompos skala kecil. Berdasarkan sosialisasi dan praktik yang telah dilakukan 0,75 Kg sampah rumah tangga yang setiap hari yang di timbun oleh setiap rumah dapat diolah menjadi kompos siap pakai.

This study was carried out to determine the effect of generator fumes on albino rats using the blood and lung histology as biomarkers. Rats were exposed to generator fumes in a five-week exposure. Blood samples were collected from the control and exposed animals weekly. The following blood parameters were tested: pH, Neutrophil, Lymphocytes, Eosinophil, Monocytes, red blood cells, and carbon monoxide. The result obtained indicate pH in week 1 was acidic (5) but the pH in weeks 5 and 4 were alkaline 7.5 and 8 respectively. Neutrophil was seen to be low in all groups from week 1 to week 5. Lymphocytes were high indicating an inflammatory response. Eosinophil in week 3, group 2, and week 5 group 3 were 0. Monocytes were normal in all groups from week 1 to week 5 except for group 4 in week 5 which was high with 10 as its value indicating the possible inception of infections. RBC in all the weeks ranged from 3.9 -5.8. Carbon monoxide was low in week 1 and high in weeks 3 and 5. The lung histology indicates hemorrhage, capillary congestion and edema. The results indicate that exposure to generator fumes predisposes one to lung damage, pulmonary edema and chronic obstructive pulmonary diseases, hence a safe distance should be kept when around an operating generator to avoid inhaling the fumes.
Vaccine Choice, Trust in Institutions, and the Intention to Get Vaccinated against SARS-CoV-2: Evidence from an Online Experiment
Authors: Aoki Naomi
Published: April 2022

Amidst the global struggle to achieve herd immunity against SARS-CoV-2, this study investigates whether the number of vaccine options (the size of the choice set) predicts the public’s intention to get vaccinated, and whether this effect depends on their trust in institutions – a system in which a collection of actors – from scientists and vaccine developers to public servants and front-line health workers – is working to fight the pandemic and to develop and approve vaccines against SARS-CoV-2 and deliver them to the public. Using an online experiment conducted in Japan (N = 600), the study tested whether choice set sizes of 1, 2, and 4 make a difference in the intention to get vaccinated. The study found that the intention was higher when the subjects were given two vaccine options to choose from, rather than offered a single vaccine, when trust was low, but this effect was negative when the subject trusted institutions highly. The study did not find strong evidence to support the effect of presenting a choice set of four. Based on these findings, this study offers nuanced suggestions for vaccine policy.

The purpose of this study was to determine the effect of the learning model on mathematics learning achievement and to determine the effect of learning motivation on students' mathematics learning achievement, and whether there is an interaction between the three variables. This research design uses a quasi-experimental design with a sampling technique that is cluster random sampling. Based on the hypothesis test using the two-way ANOVA test, three hypothetical decisions were obtained: 1) The results of the first hypothesis test stated the value of Fcount > Ftable (10.01 > 3.99), so H0 was rejected in other words the learning model affected learning achievement, through the post-anava test. the results obtained Fcount > Ftable (13.29 > 7.98), it can be concluded that the learning model in the experimental class produces better learning achievement than the learning model in the control class; 2) The results of the second hypothesis test state that Fcount > Ftable (24.98 > 3.14), so H0 is rejected, in other words, students' motivation to learn mathematics affects their learning achievement. Based on the post-anava test, it was found that high and medium students' motivation to learn mathematics resulted in better learning achievement than students with low mathematics learning motivation; 3) The result of the third hypothesis test states that Fcount > Ftable (0.22 < 3.14) then H0 is accepted, in other words there is no interaction between the learning model and the motivation to learn mathematics on students' mathematics learning achievement.

Pendidikan seni memiliki peranan krusial dalam membantu pendewasaan peserta didik, Suatu kecerdasan yang matang barangkali hanya bisa ditunjukkan dengan cara mengimbangkan (equilibrium) antara kemampuan mengoptimalkan fungsi otak belahan kanan dan kiri. Hal ini berarti bahwa kecerdasan intelektual yang bersumber pada pengoptimalan fungsi otak belahan kiri harus sebanding dengan pengembangan fungsi otak belahan kanan sebagai sumber potensi emosi dan seni. Dalam tulisan ini ’mandala’ dimengerti sebagai ’diagram magis’, artinya sebuah peta pembagian ruang, wilayah, kawasan kehidupan guna menentukan bagian-bagian mana yang memiliki kekuatan mistis-magis yang lebih daripada yang lainnya. Mandala , (Sanskrit: "lingkaran") dalam Tantrisme Hindu dan Buddha, gambarajah simbolik yang digunakan dalam pelaksanaan upacara suci dan sebagai alat meditasi. Mandala pada dasarnya adalah representasi alam semesta, daerah yang dikuduskan yang berfungsi sebagai tempat untuk para dewa dan sebagai titik pengumpulan kekuatan sejagat. Manusia (mikrokosmos), dengan "memasuki" mandala secara mental dan "melangkah" menuju pusatnya, dengan analogi dipandu melalui proses-proses kosmik disintegrasi dan reintegrasi.
