Three Decades on Russia’s Path of the Second Demographic Transition: How Patterns of Fertility are Changing Under an Unstable Demographic Policy
Authors: Zakharov Sergei V. 
Published: February 2024

This study aims to highlight the changes in fertility patterns of Russians which occurred after the USSR’s dissolution or disintegration, taking a long historical perspective. After that disruption, thirty cohorts were born and raised who never lived under the Soviet system. Fifteen more cohorts (those who were born between 1975 and 1990) remember that system only as a part of childhood, but their adult life started after the iron curtain had fallen and a flood of new ideas and practices spilled into all spheres of life.
At the same time, the increased concern among the Russian elite about the declining population and low birth rates led to the adoption of a pronatalist family policy based on monetarist approaches reinforced by conservative-traditionalist ideology.
Our main research question asks: To what extent did state social and family policies in Russia, which are based on the ideology of traditionalism and conservatism, derail or slow down the modernization of the quantitative and structural parameters of fertility patterns within the Second Demographic Transition context?
Our analysis is based on indicators from period and cohort fertility tables, specific for age and parity. Extrapolations are used for Russia’s female cohorts born 1971-1994 to arrive at expected ultimate fertility outcomes.
Our evidence, obtained from the comprehensive analysis of fertility tables, reveals that the transformation of the Russian fertility model continues to be in line with the Second Demographic Transition common to developed countries, and that two decades of active pronatalist policy in the context of strengthening the conservative family ideology did not stop the modernization of fertility patterns.

Published: February 2024

Truck-and-drone routing problems have become an important research topic in the last decade because of their applications for last-mile deliveries. Despite the many publications in this area, the most efficient exact algorithms designed thus far struggle to solve the benchmark instances with 39 or more customers. This fact holds even for one of the simplest variants involving one truck and one drone whose routes must synchronize at customers’ locations: the basic traveling salesman problem with a drone (TSP-D). In this article, we devise a new algorithm for the TSP-D that solves every benchmark instance with up to 59 customers, and it scales up to 99 customers when the drone is much faster than the truck. The core of our method is a dynamic programming algorithm that is applied for column generation and variable fixing within tailored decremental state-space relaxation strategies.

Multi-functional terahertz metasurface for a vortex beam, multi-channel focusing, polarization conversion, and broadband absorption based on vanadium dioxide
Authors: Li XiangZhong , Wei Wei , Yang XiuDan 
Published: February 2024

Although terahertz metasurface devices have been widely studied, thus far, metasurfaces can rarely manipulate both circularly and linearly polarized incident waves. In this paper, taking advantage of the phase transition characteristics of vanadium dioxide (VO2), a multi-functional terahertz metasurface for a vortex beam, multi-channel focusing, polarization conversion, and broadband absorption is proposed. When VO2 is in the insulating state, a vortex beam is generated at 1.2 THz when the circularly polarized wave is incident on the metasurface. Meanwhile, the multi-channel focusing is realized at 1.0 THz, and the cross-polarization conversion rate can reach more than 90% at the frequencies of 0.6 THz, 1.1 THz, and 1.6 THz when the y-polarized wave is incident vertically. When VO2 is in the metallic state, the metasurface achieves close to 95% absorption in the range of 0.8–1.5 THz. The designed metasurface has tunability and multi-functional characteristics, which have potential applications in wireless communication.

Published: February 2024

Background
Chagas cardiomyopathy (ChCM) is a severe form of Chagas disease and a major cause of cardiovascular morbidity and mortality. The dysregulation of the immune response leads to cardiac remodeling and functional disruptions, resulting in life-threatening complications. Conventional diagnostic methods have limitations, and therapeutic response evaluation is challenging. MicroRNAs (miRNAs), important regulators of gene expression, show potential as biomarkers for diagnosis and prognosis.

Aim
This review aims to summarize experimental findings on miRNA expression in ChCM and explore the potential of these miRNAs as biomarkers of Chagas disease.

Methods
The search was conducted in the US National Library of Medicine MEDLINE/PubMed public database using the terms “Chagas cardiomyopathy” OR “Chagas disease” AND “microRNA” OR “miRNA” OR “miR.” Additionally, bioinformatics analysis was performed to investigate miRNA-target interactions and explore enrichment pathways of gene ontology biological processes and molecular functions.

Results
The miR-21, miR-146b, miR-146a, and miR-155 consistently exhibited up-regulation, whereas miR-145 was down-regulated in ChCM. These specific miRNAs have been linked to fibrosis, immune response, and inflammatory processes in heart tissue. Moreover, the findings from various studies indicate that these miRNAs have the potential as biomarkers for the disease and could be targeted in therapeutic strategies for ChCM.

Conclusion
In this review, we point out miR-21, miR-146b, miR-146a, miR-155, and miR-145-5p role in the complex mechanisms of ChCM. These miRNAs have been shown as potential biomarkers for precise diagnosis, reliable prognostic evaluation, and effective treatment strategies in the ChCM.

Authors: Al-Otaibi Adhwa , Elimam Haga 
Published: February 2024

This study is aligned with the vision of the Kingdom of Saudi Arabia 2030, which seeks to achieve sustainable economic development. This study aims to estimate the size of the interrelationships among the economic sectors in the Kingdom of Saudi Arabia from the period 1970 to 1920. The descriptive-analytical and econometric approaches were used to display the concepts and literature review relevant to the study as well as to analyze the interrelationships between the sectors of the national economy, which are represented in: the added value of (the manufacturing sector, the non-manufacturing industries sector, the service sector, and the agricultural sector) using Vector Auto- Regression model (VAR) and Impulse Response Functions. The results showed the weakness and limitations of the interrelationships among the economic sectors in the Kingdom of Saudi Arabia, in addition to the absence of leading sectors with a strong impact on the rest of the other economic sectors and are influenced by them as well. Accordingly, the study recommends the need to continue and intensify the diversification efforts made by the government to get out of the scope of a rentier economy, and to strengthen the interrelationships among the various economic sectors by applying appropriate reform models that are integrated with economic policies in a way that achieves the requirements of sustainable economic development.

Published: February 2024

Natural flowering in pineapple crops can cause significant economic losses to growers, resulting in uneven fruiting, which hinders phytosanitary operations and the scaling of fruit harvest. The objective of this work was to evaluate the tolerance of eight pineapple cultivars to natural flowering induction in Tangara da Serra, Mato Grosso, Brazil. The cultivars BRS-Ajuba, BRS-Imperial, BRS-Vitoria, Gigante-de-Tarauaca, IAC-Fantastico, Jupi, Perola, and Smooth-Cayenne were evaluated. Planting was carried out in May of 2018, in a randomized block design, with five replications and 20 plants per plot. Plant height, D-leaf length, and percentage of induced plants were evaluated. The surveying period of plants naturally induced was between May and September 2019. In this period, the plants were between 12 and 16 months of age, with adequate D-leaf lengths and plant heights for the occurrence of flowering induction. There were days with night-time temperatures below 15 °C; the lowest photoperiod was in June. The cultivars Smooth-Cayenne, BRS-Imperial, and IAC-Fantastico were tolerant to the natural induction, which resulted in uneven fruiting, causing losses to growers.

Published: February 2024

Introduction : Primary open-angle glaucoma (POAG) is a chronic, progressive, bilateral optic neuropathy corresponding to a loss of retinal ganglion cells and characterised by morphological changes in the optic disc associated with typical visual field damage. Methods : This was a prospective, cross-sectional, descriptive, monocentric study conducted over a 5-month period from September 2020 to February 2021 in the ophthalmology department of the university hospital of Tambohobe Fianarantsoa Madagascar. The purpose of this study was to evaluate the prevalence of primary open-angle glaucoma and to describe its epidemiological and clinical aspects. Results: The prevalence of primary open-angle glaucoma in our study was 21.25% with a female predominance of 68.63%. The mean age was 50 ± 15 years. The majority of patients (80.39% ) with POAG in our study had visual acuity greater than or equal to 20/63. 49 eyes or 48.94% of the 102 eyes had ocular hypertoni greater than 21 mm Hg. The Cup/Disc ratio greater than 0.5 was found in 99 eyes (97.06%). In our study, 61 of 102 eyes had a slightly altered visual field (59.80%), 30 eyes had a moderately altered visual field (29.41%) and 11 eyes had a severely altered visual field (10.78%). Conclusion : Primary open-angle glaucoma is a chronic progressive bilateral optic neuropathy corresponding to a loss of retinal ganglion cells and characterised by morphological changes in the optic disc associated with typical visual field damage. This pathalogy is very common in Fianarantsoa.
Równowaga międzyinstytucjonalna jako kategoria analityczna w badaniach nad systemem politycznym Unii Europejskiej
Authors: Jaskulski Adam 
Published: February 2024

Celem niniejszego artykułu jest wskazanie na adekwatność stosowania do badań nad systemem politycznym Unii Europejskiej analizy poprzez pryzmat koncepcji równowagi instytucjonalnej. Przedmiotowy artykuł ma przede wszystkim charakter analityczny, a nie empiryczny, wskazując na znaczenie równowagi międzyinstytucjonalnej w jej aspekcie prawnym i politologicznym, relacje równowagi międzyinstytucjonalnej z zasadą check and balances oraz funkcję, jaką równowaga międzyinstytucjonalna spełnia w systemie politycznym UE, a także kryterium, poprzez które zmiany w równowadze międzyinstytucjonalnej można badać.
Pierwsza z hipotez badawczych weryfikowanych w niniejszym artykule stwierdza, iż istnieje konieczność odejścia od pojmowania stosunków międzyinstytucjonalnych poprzez pryzmat działalności tylko trzech podmiotów, tj. RUE, KE i PE, co miało miejsce przez wiele lat w badaniach prowadzonych nad systemem instytucjonalnym UE. Druga hipoteza badawcza zakłada, iż analiza systemu politycznego UE z użyciem zasady chceck and balances, ze względu na inne cele systemu politycznego UE niż państw narodowych, ma znacznie mniejszy potencjał eksplanacyjny, niż analiza tego systemu z użyciem koncepcji równowagi międzyinstytucjonalnej.
W artykule zastosowano następujące metody badawcze: instytucjonalno-prawną oraz neoinstytucjonalną.

AbstractLong‐COVID patients present with a decline in physical fitness. The aim of this study is to reveal the impact of pulmonary rehabilitation (PR) on physical fitness, quality of life (QoL), and parameters of quantified thorax CT. Long‐COVID patients enrolled in a 3‐month PR program were retrospectively studied. PR included endurance and resistance training three times a week. Assessments pre‐ and post‐rehabilitation included quantified chest CT, pulmonary function tests (PFT), six‐minute walk test (6MWT), cardiopulmonary exercise test, and questionnaires: Hospital Anxiety and Depression Scale, post‐COVID‐19 Functional Status scale, Borg score, and EuroQol. Seventeen subjects (5M/12F), mean age 42 ± 13 years, were included. PR improved all questionnaires' results significantly. Only significant difference in PFT parameters was correlation between baseline total lung capacity (TLC) and difference in TLC pre‐ and post‐rehabilitation (p = 0.002). 6MWT increased from 329 to 365 m (p < 0.001), VO2max changed from 21 to 24 mL/kg/min (p = 0.007), peak load increased from 116 to 141 Watt (p < 0.001). Blood volume in small pulmonary vessels of 1.25 to 5 mm2 in cross‐sectional area (BV5%) was higher than observed in patients with acute COVID‐19 infection. After rehabilitation, BV5% decreased from 65% to 62% (p = 0.020). These changes correlated directly with changes in TLC (p = 0.039). Quantified CT airway volume increased after rehabilitation (p = 0.013). After rehabilitation, TLC tended to normalize due to (re)opening of small airways, with decline in air trapping and recruitment of alveoli. Furthermore, this study revealed that pulmonary rehabilitation can improve QoL and physical fitness in long‐COVID patients.
Goethe és Schiller találkozása a filozófiában

The meeting of Goethe and Schiller in philosophy
Despite the fact that Plato did not consider poets to be explorers of truth, we find many examples of writers and poets being interested in philosophy and discussing questions of truth or morality in their literary works or studies. Likewise we know philosophers who have reflected on the truth manifested in art or literature, such as Friedrich Nietzsche, Richard Rorty or Donald Davidson. The legendary literary and philosophical friendship between Goethe and Schiller is well known in the history of literature, and their decisive intellectual relationship lasting eleven years. Their example clearly shows the influence of literature and philosophy on each other, their debate with each other, the tension or even harmony between them.
Ligeti's Autobiographies
Authors: Griffiths Paul 
Published: February 2024

AbstractLike his fellow members of the Western European musical avantgarde of the 1950s, 60s, and 70s, Ligeti often expressed himself in articles or lectures on theoretical and analytical topics. Unlike his contemporaries, however, he also wrote on matters autobiographical. Though his first self-examination, dating from 1971, is still concerned overwhelmingly with compositional theory, from the end of that decade he returned several times to personal experiences, especially those of his childhood years and early adulthood. These seemed to become important again now that the musical climate was turning from a hard objectivity that held the composer's personality to be almost irrelevant towards a fuzzier view of how composers could not but be subjectively engaged in their work. At the same time, in their variety of approach, Ligeti's autobiographical writings refuse to tell a single story.
Utopias and Their Discontents: Ligeti's Reception History as Modernist Meta-Narrative
Authors: Bauer Amy 
Published: February 2024

AbstractConservative critic John Borstlap cited Ligeti as a partisan in his fight against the modernist myth of progress in the arts, based on the famous citation “I am in a prison. One wall is the avant-garde, the other is the past. I want to escape.” Ligeti's ambivalence reflected his distaste for art linked to utopian socialist ideals, and for all that was reactionary. Yet he admitted that his own youthful utopian strivings evolved into a desire for complex music that often defied audibility. This essay traces Ligeti's reception history from the late 1950s onward as a reaction to the thwarted utopian strains in his music. For some, Ligeti's music of the 1960s seemed to define “the contemporary problem itself.” But the composer's increased visibility in the 1990s led to demands that he deal with his Jewish heritage and wartime trauma, and cease writing music with a broad appeal. I argue that Ligeti's works reinscribe the past, the personal, and the extramusical as a conscious expression of his prison. They express the nonlinear notion of progress that defines modernism: a vast “tear in the historical process” able to lift music above the scrum of political-aesthetic skirmishes, to a “region which lies elsewhere.”
The Widow in the Old House or The Elevator is Out of Order
Authors: Laki Péter 
Published: February 2024

AbstractOn several occasions, Ligeti spoke about an early literary memory that he credited with the origins of his meccanico style. He recalled reading a short story by Gyula Krúdy (1878–1933) at the age of five, in which Krúdy supposedly wrote about a widow who lived in an old house filled with constantly ticking clocks. To date, the best Krúdy experts have been unable to identify the story in question, and it is reasonable to assume that in Ligeti's mind, actual elements from the writer's work were freely recombined and reimagined at a time when the compositions partly inspired by the Krúdy experience had already been written. Ligeti's published interviews contain references to Krúdy that go beyond the story with the clocks, it may be assumed that the writer's influence on the composer goes deeper than what has been acknowledged so far.In addition, there is an aspect of Ligeti's recollection of the Krúdy story that has not received all the attention it deserves. In his conversations with Péter Várnai, the composer spoke of machines that were working or not working (emphasis mine), and elevators stopping at the wrong floor, or not starting at all. Some of the meccanico works are worth revisiting in search of such “malfunctions” as we try to reimagine the old house where not all the clocks might have been running like clockwork.
