Published: March 2024

Analysis of coupling between the phases and amplitudes of neural oscillations has gained increasing attention as an important mechanism for large-scale brain network dynamics. In Parkinson’s disease (PD), preliminary evidence indicates abnormal beta-phase coupling to gamma-amplitude in different brain areas, including the subthalamic nucleus (STN). We analyzed bilateral STN local field potentials (LFPs) in eight subjects with PD chronically implanted with deep brain stimulation electrodes during upright quiet standing and unperturbed walking. Phase-amplitude coupling (PAC) was computed using the Kullback-Liebler method, based on the modulation index. Neurophysiological recordings were correlated with clinical and kinematic measurements and individual molecular brain imaging studies ([123I]FP-CIT and single-photon emission computed tomography). We showed a dopamine-related increase in subthalamic beta-gamma PAC from standing to walking. Patients with poor PAC modulation and low PAC during walking spent significantly more time in the stance and double support phase of the gait cycle. Our results provide new insights into the subthalamic contribution to human gait and suggest cross-frequency coupling as a gateway mechanism to convey patient-specific information of motor control for human locomotion.

The dietary inflammatory index (DII) is a measure of the inflammatory potential of the diet and is closely associated with insulin resistance (IR) and stroke. And IR may play an important role in the development of stroke. Therefore, this study aimed to evaluate the relationship between DII and stroke risk while delving into the potential role of IR in this association. We analyzed data from the National Health and Nutrition Examination Survey (NHANES) from 2005 to 2018, performing weighted univariate analyses, logistic regression, and mediation analyses. At baseline, 3.89% of participants developed stroke, and we observed stroke patients exhibited higher DII scores. After adjusting for covariates, compared to participants in the first quartile of DII scores, those in the third quartile and fourth quartile had increased odds of experiencing a stroke (OR: 1.78, 95% CI: 1.18–2.68) and (OR: 1.70, 95% CI: 1.16–2.50), respectively. Moreover, a significant dose–response relationship was observed (P-trend < 0.05). However, there was no observed interaction between DII and homeostatic model assessment-IR (HOMA-IR) concerning stroke risk, and HOMA-IR did not mediate the association between DII and stroke. In summary, our study elucidated the significant association between DII and stroke risk, independent of IR. This insight suggests that an anti-inflammatory diet may serve as an effective strategy for stroke prevention.
Non-canonical RNA substrates of Drosha lack many of the conserved features found in primary microRNA stem-loops
Authors: Gu Karen , Mok Lawrence , Wakefield Matthew J. , Chong Mark M. W.
Published: March 2024

The RNase III enzyme Drosha has a central role in microRNA (miRNA) biogenesis, where it is required to release the stem-loop intermediate from primary (pri)-miRNA transcripts. However, it can also cleave stem-loops embedded within messenger (m)RNAs. This destabilizes the mRNA causing target gene repression and appears to occur primarily in stem cells. While pri-miRNA stem-loops have been extensively studied, such non-canonical substrates of Drosha have yet to be characterized in detail. In this study, we employed high-throughput sequencing to capture all polyA-tailed RNAs that are cleaved by Drosha in mouse embryonic stem cells (ESCs) and compared the features of non-canonical versus miRNA stem-loop substrates. mRNA substrates are less efficiently processed than miRNA stem-loops. Sequence and structural analyses revealed that these mRNA substrates are also less stable and more likely to fold into alternative structures than miRNA stem-loops. Moreover, they lack the sequence and structural motifs found in miRNA stem-loops that are required for precise cleavage. Notably, we discovered a non-canonical Drosha substrate that is cleaved in an inverse manner, which is a process that is normally inhibited by features in miRNA stem-loops. Our study thus provides valuable insights into the recognition of non-canonical targets by Drosha.
Inducing room-temperature valley polarization of excitonic emission in transition metal dichalcogenide monolayers
Authors: Morozov Sergii , Yezekyan Torgom , Wolff Christian , Bozhevolnyi Sergey I. , Mortensen N. Asger
Published: March 2024

The lowest energy states in transition metal dichalcogenide (TMD) monolayers follow valley selection rules, which have attracted vast interest due to the possibility of encoding and processing of quantum information. However, these quantum states are strongly affected by temperature-dependent intervalley scattering leading to complete valley depolarization, which hampers practical applications at room temperature. Therefore, for achieving clear and robust valley polarization in TMD monolayers one needs to suppress parasitic depolarization processes, which is the central challenge in the growing field of valleytronics. Here, in electron-doping experiments on TMD monolayers, we show that strong doping levels beyond 1013 cm−2 can induce 61% and 37% valley contrast at room temperature in tungsten diselenide and molybdenum diselenide monolayers, respectively. Our findings demonstrate that charged excitons in TMD monolayers hold the potential for the development of efficient valleytronic devices functional at 300 K.

Published: March 2024

Wild fish used as aquafeeds could be redirected towards human consumption to support sustainable marine resource use. Here we use mass-balance fish-in/fish-out ratio approaches to assess nutrient retention in salmon farming and identify scenarios that provide more nutrient-rich food to people. Using data on Norway’s salmon farms, our study revealed that six of nine dietary nutrients had higher yields in wild fish used for feeds, such as anchovies and mackerel, than in farmed salmon production. Reallocating one-third of food-grade wild feed fish towards direct human consumption would increase seafood production, while also retaining by-products for use as aquafeeds, thus maximizing nutrient utilization of marine resources.

Published: March 2024

Increasingly, climate activists use nonviolent civil disobedience (NVCD) to raise awareness about the need to end fossil fuel use. In two small studies we explored the potential of NVCD to enhance U.S. public support for this goal. Study 1 showed that some NVCD actions (e.g., marches and sit-ins) and some targets of those actions (e.g., fossil fuel companies) are seen as more acceptable than other targets (e.g., ordinary people). Study 2 suggested that perceived acceptable NVCD actions against perceived acceptable targets may be more effective than other forms of NVCD. We provide some potential directions for future research to better elucidate understanding on this topic.
Emotion regulation flexibility and momentary affect in two cultures
Authors: Chen Mark Shuquan , Bi Kaiwen , Han Xuerui , Sun Pei , Bonanno George A.
Published: March 2024

Recent theoretical models highlight the importance of emotion regulation (ER) flexibility, challenging traditional notions of universally maladaptive versus adaptive strategies. Here we employed ecological momentary assessment to develop proxy ecological measures for ER flexibility components (context sensitivity, repertoire and feedback responsiveness) and examine their associations with momentary affective outcomes in two independent samples from the United States (158 adults and 12,217 observations) and China (144 adults and 11,347 observations, analysis preregistered). Participants completed four daily surveys for 21 days, reporting emotional situations, situation characteristics, ER use and change and momentary distress. Increased momentary context sensitivity and use of repertoire were found associated with reduced distress, while results for feedback responsiveness were less consistent. Maintaining effective strategies was generally adaptive, whereas switching from ineffective strategies was adaptive for momentary depressed, but not anxious, mood. This innovative ecological momentary assessment design demonstrates transcultural similarities in ER flexibility’s benefits and nuanced implications of its components on affective outcomes.

Study experiment on the way forest plantation microclimate influences human hemodynamic parameters
Authors: Tsaralunga A. , Korotkaya A. , Zenishcheva O.
Published: March 2024

In recent years, the flow of vacationers in the forests of cities’ green areas has significantly increased. In this regard, it raises the question about the influence of various forest plantations, or rather the "microclimate" of various types of forest conditions, on hemodynamic parameters of a healthy person. In everyday life, for example, there are cases when people's staying in a pine plantation causes malaise, dizziness, weakness, and even fainting. The research was carried out in various forest plantations, the most typical for the green zone of Voronezh city according to meteorological conditions. Studies of the state of vital organs and systems of a healthy person show that the "microclimate" of various forest stands is not indifferent to a person and causes him a number of changes in hemodynamics. The noted changes in hemodynamics suggest that mixed plantings, multi-tiered, do not cause drastic changes in the body of a healthy person. The main criterion for the training of new cities’ green areas and the reconstruction of existing ones should be the creation of complex, multi-tiered plantings, especially for short-term recreation.

Authors: Zyryanov М.А. , Medvedev S.О. , Mokhirev А.P.
Published: March 2024

In the present work the justification of the urgency of solving the issue of environmental friendliness of materials produced from wood resources is given. The analysis of the production technology of semifinished wood-fiber products is carried out at the current stage of development of the board industry. The estimation of board formation properties of the wood fiber mass produced in disk blade grinding machines is given, and the inefficiency of the used equipment is substantiated. The expediency of using the equipment with cavitation effect as the second grinding stage in the production of wood pulp was substantiated. As a result, the purpose of the present work was the development of the technology for the production of the semifinished wood fiber product with the use of a rotor-pulsation apparatus as the second stage of the wood pulp mill. To achieve the goal, an analysis of modern technologies used in the production of fiberboard was carried out. The model of technological scheme of production of wood fiberboards by wet method in the environment of AnyLogic program package was developed. Based on the technological scheme developed, a dynamic model of the fiberboard production process was built using a rotor-pulsation apparatus in the second stage of wood pulp milling. In the course of research, statistical analysis methods and simulation modelling of technological processes were applied. The results obtained can find application in the production of fiberboard, as well as in the improvement of technological processes at the enterprises of the forest complex.

Authors: Yakusheva Maria , Mokhirev Aleksander , Dudin Pavel
Published: March 2024

The paper presents the results of scientific research of certain features of wood resources processing at the enterprises of the forest industry. Considering that the forest industry is actively developing, the volumes of processed raw materials are increasing, the amount of generated secondary wood resources (waste) is increasing. The purpose of the work is to identify some key features of their use. For this purpose, the analysis of literary sources was used. Practical experience of domestic and foreign timber companies was also considered. As a result, a significant lag of the Russian timber industry from foreign best practices was revealed. In particular, the volume of manufactured products is significantly inferior to those of timber reserves and processed raw materials. This is due to the low share of participation and efficiency in the utilization of secondary wood resources. Another important conclusion was that the main problem in terms of the secondary wood resources utilization is to find optimal ways of using secondary wood raw materials. Significant volumes of wood waste generation in various technological processes were shown. Separate requirements were revealed and demonstrated to the initial raw materials to obtain products from the raw materials of wood. An important outcome was that the higher feedstock requirements of large-scale production facilities were identified. Smaller production facilities are often more flexible and adaptable to the available resources.

Patterns of air temperature changes in air ducts of non-contact air heating or cooling systems
Authors: Sargsyan Samvel , Agafonova Vera
Published: March 2024

The article is devoted to the study of the patterns of changes in air temperature during its movement in a sheet steel air duct during the operation of non-contact air heating systems, when the temperature of the moving air through the duct is higher than the room air temperature, as well as in the process of non-contact air cooling, when the temperature of the moving air in the duct below the room temperature. Based on the mathematical model of the ongoing physical processes developed in the article, an analytical formula is derived that allows, taking into account the presence of a heat-insulating layer or without it, to determine the patterns of changes in the temperature of moving air through the air duct at a given distance, depending on the thickness of the wall of the air duct and the speed of its movement. A dependence is given that determines the value of the heat transfer coefficient of air moving inside the duct to the inner surface of the duct on the speed, which at a constant flow rate is presented as a dependence of heat transfer on the open cross-sectional area of the duct. An analysis was carried out of the change in temperature of the moving volume of air inside the duct as a result of heat exchange with the surrounding air. A comparative calculation of the change in temperature of air moving in a thermally insulated air duct and in an air duct without thermal insulation was performed. The necessity of carrying out a calculation to determine the patterns of changes in the temperature of moving air inside the air duct when designing air heating systems or air conditioning systems is substantiated. It is concluded that it is necessary to conduct a technical and economic analysis on the feasibility of installing thermal insulation of air ducts made of thin sheet steel.

Published: March 2024

World statistics show a steady increase in greenhouse gas emissions in the planet's atmosphere. Сontinuous growth of greenhouse gas markets occurred despite the financial crisis (2008) and the pandemic (2019-2022). Currently there are about 70 market mechanisms in the world that capture some 20% of greenhouse gas emissions. Despite obvious progress, the terms of the Paris climate agreement are far from being met. The current situation requires the global community to strengthen measures to combat climate change. New approaches are needed to develop market-based instruments to achieve climate goals. The study explores the volumes and trends the market economic mechanisms abroad. These mechanisms can cover a significant part of greenhouse gas emissions. Russia has so was not involved in the development of global carbon markets, unlike its western and eastern neighbors. The study of the experience of these countries is necessary for the successful assertion of national Russian interests in the global carbon policy and markets. Carbon credits are traded on a mandatory and voluntary markets. They are divided into primary and secondary. Carbon markets reached $800 billion in 2021, more than international trade in grains or oil. Voluntary markets have surpassed the $800 million mark and continue to grow rapidly. It is expected that by 2030 their volume will be at least 100 billion US dollars. The current study highlights promising directions for the Russian carbon markets, taking into account world experience and development trends.
