We report on an in-band pumped SESAM mode-locked Ho:CALGO bulk laser with a record-high average power of 8.7 W and an optical-to-optical efficiency of 38.2% at a central wavelength of 2.1 µm. At this power level, the bulk laser generates pulses with a duration of 369 fs at an 84.4-MHz repetition rate, corresponding to a pulse energy of 103 nJ and a peak power of 246 kW. To the best of our knowledge, this is the highest average power and pulse energy directly generated from a mode-locked bulk laser in the 2-3 µm wavelength region. Our current results indicate that Ho:CALGO is a competitive candidate for average power scaling of 2-µm femtosecond lasers.

Background

The Patterns of non-Adherence to Anti-Platelet Regimen in Stented Patients (PARIS) thrombotic risk score has been proposed to estimate the risk of stent thrombotic events after percutaneous coronary intervention (PCI). However, the prognostic value of the PARIS thrombotic risk score for long term all-cause and cardiac mortalities, as well as hospitalization due to heart failure, has not yet been evaluated. Therefore, the aim of the present study was to evaluate the prognostic value of the PARIS thrombotic risk score for all-cause and cardiac mortalities and hospitalization due to heart failure following PCI.

Methods and results

Consecutive 1,061 patients who underwent PCI were divided into three groups based on PARIS thrombotic risk score; low- (n = 320), intermediate- (n = 469) and high-risk (n = 272) groups. We followed up on all three groups for all-cause mortality, cardiac mortality and hospitalization due to heart failure. Kaplan-Meier analysis showed that all outcomes were highest in the high-risk group (P < 0.001, P = 0.022 and P < 0.001, respectively). Multivariate Cox proportional hazard analysis, adjusted for confounding factors, showed that the risk of all-cause mortality and hospitalization due to heart failure of the high-risk group were higher than those of the low-risk group (hazard ratios 1.76 and 2.14, P = 0.005 and P = 0.017, respectively).

Conclusion

The PARIS thrombotic risk score is a significant prognostic indicator for all-cause mortality and hospitalization due to heart failure in patients after PCI.
The Hyphenated Spelling as a Stage in the Formation of Particle же spelling.
Authors: Kaverina Valeriia , Zhao Pengxiang
Published: September 2022

The article is devoted to hyphenating particles, like же(жъ) in the 19th century. The purpose of the article is to state a codified and common spelling norm, trace its dynamics and find out the role of the hyphenated use of particles played at this stage. Particle spelling codification is represented in academic dictionaries and grammars of the 19th century. The article presents some facts of codification and patterns of the use of a hyphen in the design of words of this part of speech. However, throughout the 19th century, the particle же(жъ) is written with a hyphen, though the number of separate spellings exceeds the number of hyphenated. Having analyzed the patterns with the particles же(жъ), Ya.K. Grot finally legalized their separate spelling in the works of analytical and codifying nature at the end of the 19th century.
Interaction of Modus Categories “Evidentiality” and “Modality” in Mass Media Discourse
Authors: Kozlovsky Dmitry
Published: September 2022

The article examines the types of synergistic link of evidentiality with the category of "modality". The category of "evidentiality", initially associated with presentation of the source of information about the event, reveals additional modus semantics in the framework of the linguosynergetic approach of discourse analysis. The author of the research states that evidentiality connects three interacting areas – the author's, the subject's, and the area of the addressee / reader. The study of the features of these areas functioning in the context of the linguosynergetic method of discourse analysis allows one to describe a synergetic evidential model that reflects the specifics of the relationship between the modus categories "evidentiality" and "modality". Analysis of evidential discourse contexts indicates that these categories represent two possible types of interaction based on the principles of complementarity and interpenetration of modus meanings in the news mass media discourse.
Diminutives in the Translation of Film Speech of Characters in Children’s Animated Films
Authors: Ulanovich Oksana
Published: September 2022

Diminutive forms of the Russian language are considered by the author of the article from the perspective of their functional-semantic syncretism and communicative-pragmatic potential, manifested in everyday communication with children in the Russian-speaking environment and in the film speech of characters in children’s animated films. The tendency of the prevalence of diminutive forms in Russian-language translations of children's animated films over those in the English-language originals, discovered by the author, is qualified by the author as a translation strategy of emotive replacement. Emotive replacement allows one to solve a number of translation tasks during the process of children’s films localization. These are: stylization of film speech in translation and lending the dialogues of film characters a child-centric coloring, expressivization of film speech through imparting additional effects of irony, appraisal, implicit aggression and jesting.
The Last Bow by V. P. Astafyev as a Family Saga
Authors: Rayhan Md Tapu
Published: September 2022

This article concentrates on the study of V. P. Astafyev's book The Last Bow in order to identify the style, subject matter and those features of this book that demonstrate the elements of the family saga genre and largely determine its integrity in this way. This paper studies The Last Bow through component analysis. It is shown that the concept of the family saga in this book is a thematic device used to depict specific historical events, changes in social circumstances and personal relationships, where the fate of individual characters is presented from different points of view. In addition, the use of critical analysis carried out in the context of a given theoretical approach allows us to identify those elements and characteristics that let us consider this book as a full-fledged representative of the family saga, where individual stories of family members from different generations acquire a new dimension. Thus, this study aims to show that The Last Bow is one of the best examples of the genre of family saga not only in Russian, but also in the world literature of the twentieth century.
The Problem of Term Choice for the Linguistic Description of the Concept of Easy Language
Authors: Mikhienko Zhanna
Published: September 2022

The article describes the options for designating the sociolinguistic concept of Easy Language, which appeared in Europe in the second half of the last century. The concept includes rules and norms on the basis of which modified texts are created. The recipients of the modified texts are readers with cognitive peculiarities. Now the concept has different names: "clear language", "plain language", "easy language", "easy to understand language", "easy reading", "simplified language". The article examines the reasons for the diversity of terms in European countries. The relevance of the problem of choosing terms to describe the concept of an easy language in Russia is also grounded. The author draws attention to the experience of creating adapted texts in the field of teaching Russian as a foreign language. It also analyzes the use of the term "clear language" in Russian linguistics in the sense in which it is used in the international concept of Easy Language. The article gives examples of overcoming terminological diversity: the creation of international reference books and bilingual dictionaries.
Pertahanan dan Keamanan di Selat Malaka Terhadap Meningkatnya Tren Piracy dan Konsistensi Kebijakan Publik serta Konsesi Wilayah Litoral State

Published: September 2022

Hadirnya pembajakan di Selat Malaka bukan merupakan hal yang baru. Orang laut merupakan sekumpulan perompak yang tunduk atas nama negara sebagai privateer pada masa Kerajaan Melayu. Kehadirannya resmi dan mendistribusikan ‘pajak’ lewat kapal-kapal niaga untuk dibagi hasil dengan negara sebagai otoritas tertinggi. Saat ini eksistensi pembajakan di Selat Malaka dipandang sebagai sesuatu yang bernada negatif, hal ini mengingat Selat Malaka merupakan sea line of communication terpenting di dunia yang menghubungkan pelayaran dari Samudra Hindia ke Samudra Pasifik begitu pula sebaliknya. Indonesia sebagai salah satu negara yang bertanggung jawab di atasnya masih menemukan formulasi yang tepat bagaimana mengatasi persoalan ini. Mulai dari pembentukan instrumen hukum di dalam negeri, implementasi dari hukum, hingga kerangka kerja sama dengan negara tetangga. Tiga elemen penting ini kemudian mendapatkan hambatan dan tantangan dari persoalan domestik seperti kurangnya efektivitas akibat banyaknya stakeholder yang berkepentingan dalam kebijakan penegakan hukum di atas laut terhadap para pembajak. Kehadiran Bakamla beserta TNI-AL dan Polair dapat menjadi contoh, betapa pemerintah belum bisa membagi tugas siapa penegak hukum di atas perairan, patroli rutin, dan fungsi angkatan laut sebagai blue-water navy. Untuk itu masuknya Indonesia dalam kerja sama patroli ReCAAP dan ASEAN Maritime Forum adalah dua dari beberapa opsi yang dapat ditempuh Indonesia untuk menegakkan kedaulatan di atas perairan dan memandu Indonesia untuk meraih visi kejayaan maritim di bawah Presiden Joko Widodo, PorosMaritim Dunia.Kata kunci: Pembajakan, Poros Maritm, Pertahanan dan Keamanan, ReCAAP, ASEAN Maritime For um.
