The Influence of China and the United States on the Secession of Taiwan in 2016–2024: Quantification of Factors of Involvement
Authors: Prikhodchenko A. , Tokarev A.
Published: July 2024

The article is devoted to the analysis of relations in the China-Taiwan-USA triangle, from the point of view of the theory of the multidirectional development of two aspects of statehood under the secession of the island: status and stateness. The authors give an answer to the question of what pressure US and China provide on the status and solvency of Taiwan in 2016–2022, analyzing military, political, economic and demographic factors through their qualitative analysis and quantification. Military variables include the facts of the flag demonstration on the territory of Taiwan and the supply of weapons, economic variables include the volume of imports and exports, trade in goods strategically important for the island’s economy, the volume of FDI, passenger and sea traffic, and the number of flights. The visits of officials, the recognition of Taiwanese documents are political variables, as well as the specifics of political communication – this meant the characteristics of unofficial contacts between Beijing and Washington with the island in a particular year. Among the variables of human capital, the number of Taiwanese students studying on the mainland and in the United States and the number of passport holders stand out. Since the authors are interested in the dynamics of Taiwan’s relations with the United States and China, static indicators were not included in the object of analysis: the presence of embassies, deterministic legal recognition. Within the framework of the work, a comprehensive approach is presented, simultaneously considering Taiwan’s involvement in relations with the United States and China. According to the results of the analysis, it is recorded that Beijing exerts the greatest pressure on the state solvency and status of the island in terms of economic and demographic aspects of interaction. In turn, the United States supports Taipei on the political and military trade track. It is predicted that China will not reintegrate Taiwan militarily in the absence of escalation by the island or the United States (unilateral recognition of independence). The Chinese strategy assumes the smooth involvement of Taiwan with economic, international-political, infrastructural instruments, the reaction to Nancy Pelosi’s visit does not mean weakness of the leadership. In addition, the Chinese foreign policy and military culture does not imply drastic actions.
Institutional Features of the Fourth Energy Transition
Authors: Loktionov V. , Yenikeyeff S.
Published: July 2024

The world has experienced three energy transitions, which were accompanied by large-scale institutional changes that determined global energy development trends. As in previous cases, the current energy transition, defined as the shift to sustainable energy, is accompanied by significant changes in the institutional environment. The fourth energy transition, unlike previous ones, which were the result of a combination of objective factors, is a kind of global experiment. The governments of Western countries have done voluntary changes in the global institutional environment in order to create a certain track of change in the global energy industry. The launch of the fourth energy transition could not take place without legal and financial support for energy projects that met the principles of sustainable development. Nevertheless, the next institutional changes, that increase the likelihood that the transformation process in the global energy sector will become a self-sustaining process, have taken place. A global public narrative has appeared, describing in a concise, simplified and emotionally charged form the need for sustainable energy, the mechanisms for achieving it and the factors hindering its development. The narrative leads to stabilization of the transition through influencing on the political decision-making process and supporting self-sustaining replication mechanisms. The narrative makes the practice of corporate social responsibility activities compulsory for large energy companies. Another trend that has emerged in the current energy transition is the shift from centralized to network organizational structure of local energy systems. The network organizational structure of energy systems, supported not only by the spatial dispersion of a larger number of energy facilities, but also by the increased diversification of the types of facilities, leads to the formation of global homogeneity and local differentiation. Identified changes in the global institutional environment make a significant impact on the dynamics of the development of local energy systems and create stable trends that could proceed independently of the still significant government support.
“Chinese Coaster” – 2: at the Turn of 2023–2024
Authors: Mikheev V. , Lukonin S.
Published: July 2024

The most important event in the China–U.S. relations at the end of 2023 was the meeting of Xi Jinping and J. Biden in San Francisco on the sidelines of the APEC Summit in November 2023. The meeting did not become a breakthrough in relations between the two countries, but it created the foundations for establishing cooperation in mutually beneficial areas. Agreements were reached on the restoration of military contacts, the resumption of activities of working groups on economic and financial cooperation, the development of cooperation in the fields of artificial intelligence, green economy, climate change, etc. At the same time, many economic and political issues remained unresolved: American trade and economic sanctions against China, and, most importantly, disagreements over Taiwan. Against the background of the China–U.S. Summit, Beijing policy has strengthened its two-vector nature. Before the Summit in the United States, a Sino-Russian Summit was held in Beijing in October 2023. Later, in December 2023, the China–EU Summit took place. Their results are contradictory. Xi described Sino-Russian relations as “healthy and stable”. The Summit with the EU ended almost to no avail. An important foreign policy move made by Beijing was the Belt and Road Summit of October 2023, at which Chinese plans to institutionalize this strategy were announced, including the creation of the Belt and Road secretariat and “other institutions”, supported with 100 bln U.S. dollars injections. In domestic politics, Xi’s authoritarianism continued to strengthen, accompanied by restrictions on the freedom of speech. In the economy, China kept the GDP growth rate for 2023 in the desired range from 5 to 5.5%. The main task for Beijing in the field of economics for 2024 is at least to keep the growth rate of the national GDP at about 5%.
A Novel Lock-in Amplification-Based Frequency Component Extraction Method for Performance Analysis and Power Monitoring of Grid-Connected Systems
Authors: Rehman Abdur , An Taeho , Choi Woojin
Published: July 2024

In recent times, the increasing concern for climate control has led to the widespread application of grid-connected inverter (GIC) based renewable energy systems. In addition, the increased usage of non-linear loads and electrification of the transport sector cause ineffective grid-frequency management and the introduction of harmonics. These grid conditions affect power quality and result in uncertainty and inaccuracy in monitoring and measurement. Incorrect measurement leads to overbilling/underbilling, ineffective demand and supply forecasts for the power system, and inefficient performance analysis. To address the outlined problem, a novel three-phase frequency component extraction and power measurement method based on Digital Lock-in Amplifier (DLIA) and Digital Lock-in Amplifier Frequency-Locked Loop (DLIA-FLL) is proposed to provide accurate measurement under the conditions of harmonics and frequency offset. A combined filter with a lowpass filter and notch filter for DLIA is employed to improve computation speed. A comparative study is performed to validate the performance of the proposed power measurement method, by comparing the proposed method to the windowed interpolated fast Fourier transform (WIFFT). The ZERA COM 3003 (a commercial high-accuracy power measurement instrument) is used as the reference instrument in the experiment
Parametrization of Fluid Models for Electrical Breakdown of Nitrogen at Atmospheric Pressure
Authors: Dhali Shirshak Kumar
Published: July 2024

In transient phase of an atmospheric-pressure discharge, the avalanche turns into a streamer discharge with time. Hydrodynamic fluid models are frequently used to describe the formation and propagation of streamers, where charge particle transport is dominated by the creation of space charge. The required electron transport data and rate coefficients for the fluid model are parameterized using the local mean-energy approximation (LMEA) and the local field approximation (LFA). In atmospheric pressure applications, the excited species produced in the electrical discharge determine the subsequent conversion chemistry. We performed the fluid model simulation of streamers in nitrogen gas at atmospheric pressure using three different parametrizations for transport and electron excitation rate data. We present the spatial and temporal development of several macroscopic properties such as electron density and energy, and the electric field during the transient phase. The species production efficiency which is important to understand the efficacy of any application of non-thermal plasmas is also obtained for the three different parametrizations. Our results suggest that at atmospheric pressure all three schemes predicted essentially the same macroscopic properties. Therefore, a lower order method such as LFA which does not require the solution of the energy conservation equation should be adequate to determine the streamer macroscopic properties to inform most plasma-assisted applications of nitrogen containing gases at atmospheric pressure.

Authors: Zabara Ilia Denisovich , Shirobokov Maksim Gennadievich
Published: July 2024

The method of searching for the orbit of a spacecraft to prevent a collision with space debris is considered. The work consists of two parts. The first part of the work addresses the problem of finding a safe orbit, geometrically closest to the original orbit, in order to avoid collisions with space debris objects. The initial orbit, orbits of space debris objects, and the minimum allowable distance from them are considered as given. The applied method of external penalty functions for solving the resulting optimization problem is described. The second part of the work consists in determining the relationship between the navigational uncertainty of the space debris object's orbit and its maximum deviation from the predicted position. The corresponding semi-analytical dependence is found for objects moving in sun-synchronous orbits and ``Molniya'' type orbits.

Authors: Danuwikarsa M. Ibrahim , Udiarto Bagus K. , Maulana Dick Dick , Suaidah Asri
Published: July 2024

Shallots are a valuable commodity in Indonesian civilization. However, due to different obstacles, production remains low. The prevalence of purple blotch disease caused by Alternaria porri is one of the major challenges in shallot production. A fungus infects its host through the stomata. The use of resistant cultivars is one of the initiatives to combat purple blotch disease. This study aimed to determine the resistance of several shallot varieties to purple blotch disease, identify and obtain resistant shallot varieties, and determine the relationship between stomatal density and the average intensity of the purple blotch disease attack. This study uses shallot cultivars released by the Balai Penelitian Tanaman Sayuran (BALITSA) Lembang. This study employed a randomized completely block design (RCBD) with ten shallot varieties as the treatments with three replications. The Agrihorti-1 and Katumi varieties had the lowest attack intensity, while the Sembrani and Maja Cipanas varieties had the highest assault intensity. Bima Brebes, Trisula, Mentes, Violetta-1, Kramat-1, Agrihorti-1, Agrihorti-2, and Katumi varieties were resistant to purple blotch disease, however, Sembrani and Maja Cipanas were susceptible. A low or weakly positive association exists between stomata density and the mean intensity of purple blotch illness.

Published: July 2024

One of the main pests that attack corn plants is Spodoptera frugiperda J. E. Smith. The usual control of this pest is by using synthetic insecticides, but the continuous or unwise use of synthetic insecticides will have negative impacts on humans and the environment, therefore alternative insecticides that are safe and environmentally friendly, such as tuba root (Derris elliptica Benth) are needed. This study aims to determine the effect of tuba root extract phytopesticide on S. frugiperda larvae and to determine the concentration of tuba root extract that is effective in controlling S. frugiperda larvae, as well as the eating inhibition power of S. frugiperda larvae after administration. The research was conducted at the Applied Entomology Laboratory, Faculty of Agriculture, Universitas Gadjah Mada, Yogyakarta from September to November 2022. The treatment concentrations used were 0, 2, 4, and 8 mL.L-1 of water. The experiment employed Completely Randomized Design (CRD) with four treatments and five replications. The results showed that the concentration of 4 mL.L-1 of water is an effective concentration for controlling S. frugiperda larvae and can cause a total mortality of 82% with an initial death of 19 hours, Lethal Time 50 at 39.20 hours after application. In addition, the concentration of tuba root powder extract of 8 mL.L-1 of water appeared to be the highest in reducing the appetite of larvae compared to other treatments with a rate of 17.03%. This showed the highest reduction in larval appetite compared to other treatments. A small amount of feed eaten means a high level of antifeedant activity.

Extended use of synthetic chemical fertilizers may degrade soil quality. As a synthetic chemical fertilizer substitute, organic fertilizer can improve soil quality, produce healthier agricultural products, and be environmentally sustainable. Thus, coffee grounds liquid organic fertilizer may solve this problem. This study examines how liquid organic fertilizer made from coffee grounds affects land kale's physiological and growth characteristics. A fully randomized experimental design with one factor and 11 treatments was used. A control group, NPK-16-16-16 4 g, and Arabica, Robusta, and Liberica coffee were treated with three concentrations (4 mL.L-1, 12 mL.L-1, and 20 mL.L-1). Four replicates were run for each treatment. The investigation found that coffee ground liquid organic fertilizer does not meet Minister of Agriculture Decree 261/KPTS/SR.310/M/4/2019 criteria. Compared to the control group, liquid organic fertilizer made from coffee grounds did not increase land kale growth. Additionally, it did not grow as well as with NPK16-16-16 fertilizer. Coffee grinds liquid organic fertilizer only enhances kale growing on land, promoting sustainable agriculture.

Authors: Mehdian Hossein , Pasku Dritan , Najjar Elie , Quraishi Nasir A.
Published: July 2024

Case:

A 28-year old male patient was involved in a RTA and sustained a highly comminuted L4 burst fracture with more than 90% canal compromise.

Considering the complete loss of power in the respective myotomes but the preservation of sacral sparing there were controversially different surgical options. We successfully performed a posterior only surgical procedure, which applied a modified transpedicle access technique to decompress the spinal canal and to restore the anterior column, achieving full neurological recovery at the final follow-up.

Conclusion:

A well-planned and executed posterior surgery alone can achieve excellent clinical and radiological result in the treatment of severely comminuted lumbar fractures.

Published: July 2024

Case:

A 71-year-old man with castration-resistant Stage IVB prostate cancer developed symptomatic oligometastatic disease in the lumbar spine and bilateral proximal femurs. He was treated with a single-position L2-L4 kyphoplasty with concomitant prone left-sided femoral prophylactic cephalomedullary nailing. Six months later when he again lost the ability to ambulate, he was treated with a single-position L4-L5 laminectomy for an epidural tumor with prone right-sided femoral prophylactic cephalomedullary nailing.

Conclusion:

Single-position prone surgery of the spine and prone femoral nailing is feasible and improves on traditional multiposition approaches, eliminating the need to reposition or change tables during management.
Defining and Differentiating Congenital Vertical Talus and Congenital Oblique Talus
Authors: Mosca Vincent S. , Ganjwala Dhiren , Shah Hitesh
Published: July 2024

Background:

Congenital vertical talus (CVT) and congenital oblique talus (COT) are rocker-bottom foot deformities that have similar names and no objective definitions. This has led to confusion for practitioners, as well as scientific challenges for researchers. Our goal was to provide objective radiographic criteria to define and differentiate CVT and COT.

Methods:

We evaluated 62 pairs of maximum dorsiflexion and plantar flexion lateral radiographs of infant feet that had been clinically diagnosed with CVT. The dorsiflexion tibiotalar angle, the plantar flexion talus-first metatarsal angle, and the plantar flexion foot center of rotation of angulation (foot-CORA) were measured using transparent overlay tools. Freehand measurements were made on a subset of 10 pairs of radiographs to confirm clinical applicability. Nine contralateral pairs of radiographs of normal feet were measured for comparison.

Results:

Specific values for the radiographic measurements were identified that, together, reliably differentiated the shapes of rocker-bottom feet with CVT, COT, and flexible flatfoot with a short tendo-Achilles (FFF-STA), as well as the shape of the normal foot. More severe and rigid rocker-bottom foot deformities were diagnosed with CVT. Less severe and more flexible deformities were diagnosed with COT.

Conclusions:

CVT, COT, FFF-STA, and normal feet can be reliably differentiated using 2 angular measurements and 1 bone position measurement on dorsiflexion and plantar flexion lateral radiographs. Our data indicated that the differentiation of CVT and COT is based primarily on the rigidity of the navicular dislocation rather than the verticality of the talus. The data further supported the proposition that COT is a foot deformity along a spectrum of valgus/eversion deformities of the hindfoot that requires early treatment. Application of these diagnostic criteria should lead to clinical studies that identify a specific treatment, treatment outcome, and prognosis for each deformity.

Level of Evidence:

Diagnostic Level II. See Instructions for Authors for a complete description of levels of evidence.
The Metaphysics of Concepts: Contemporary Approaches
Authors: Bulov Ilya ,   Institute of Philosophy, Russian Academy of Sciences
Published: July 2024

The article is an overview of the contemporary approaches to the metaphysics of concepts. We have attempted to show the complexity of the discussion about the metaphysics of concepts, as well as the diversity of modern philosophical positions on this issue. Representationalism and Fregeanism are still the most popular ap­proaches to the metaphysics of concepts. In the first part we discuss the main ideas and possible drawbacks of the mainstream views – representationalism and Fre­geanism. Representationalist view considers concepts as mental representations, whereas Fregeanism states that concepts are Fregean senses. In the second part we briefly discuss the less popular approaches: the mixed view, eliminativism and abilitism. According to the mixed view, concepts are mental representations typed in terms of the Frege’s senses they express. Eliminativism is in favor of eliminat­ing the term “concept”. The abilitism supporters suppose that concepts are mental ca­pacities.
Antiutopia and Stalinism: J. Orwell’s novel “1984”
Authors: Yurganov Andrey ,   Russian State University for the Humanities
Published: July 2024

The article deals with the interaction of dystopian and utopian genres in the main dystopian work of the XX century – J. Orwell’s novel “1984”, which arouses the undying interest of philosophers, culturologists, historians, who try to find the meaning of the novel in different models of generalizing knowledge, but also on the path of ambivalent inter­pretations, when it is taken as an axiom that a utopian image can combine multidirec­tional characteristics without violating the meaningful integrity of the work. The task of this study is to understand the author’s meaning of the novel on the basis of the fact that any work must have natural boundaries of self-consciousness that do not contradict the historical and cultural context of its inherent modernity. Within these boundaries the novel “1984” appears before us as a novel written not only by a man committed to the ideals of world socialism, but also by a Trotskyist who shared L.D. Trotsky’s criti­cal judgments against the usurpation of the proletariat’s rights to power by Stalin’s party.
Dual role of KHCO₃ priming: reduces seed-borne pathogens on sorghum seeds and promotes seed germination
Authors: Dong Shuai , Peng Keqin , Liu Qiyuan , Zhang Min , Luo Yan , Li Zhen hua
Published: July 2024

Background
Seed-borne diseases have seriously affected the sustainability of sorghum cultivation in China as the demand for organic products in the winemaking industry has limited the use of chemical fungicides.
Results
This study conducted a comprehensive analysis of fungal diversity in sorghum seeds from three major growing regions in Guizhou Province. Using a combination of traditional tissue separation and high-throughput sequencing, we identified Colletotrichum, Fusarium, Cladosporium, and Alternaria as dominant fungi. Pathogenicity tests revealed that strains GD202206, GD202219, and GD202242 were pathogenic and were identified as C. sublineola through morphological and multi-locus phylogeny analysis (ITS、CAPDH、ACT、CHS-1 and TUB2). 16 fungicides for seed priming experiments with sorghum seeds, the results indicated that priming with KHCO₃ significantly enhanced germination of the sorghum seeds, with both indoor and outdoor emergence rates notably higher. Analysis of the fungal changes before and after KHCO₃ priming revealed a significant reduction in the abundance of the Colletotrichum genus. Additionally, KHCO₃ altered the community structure of fungi within the sorghum seeds, reducing population richness. Inter-generic relationships were rebalanced, with antagonism decreased and synergy increased following KHCO₃ treatment. Non-target metabolomic analysis indicated that KHCO₃ enhances sorghum seed germination via the phenylalanine and flavonoid pathways and exhibits antifungal properties through the cyanoamino acid metabolic pathway.
Conclusion
This study identified C. sublineola as the primary pathogenic fungus carried by sorghum seeds. KHCO₃ treatment has a dual effect on sorghum seeds: on one hand, it suppresses pathogen transmission by reducing the abundance of the Colletotrichum genus; on the other hand, it promotes germination and seedling emergence, thereby enhancing both germination and emergence rates.

Published: July 2024

Background:Digital health literacy plays a crucial role in people's access to reliable information and making health-related decisions. While the levels of digital health literacy in the general population have been widely studied, there is limited research on the status of digital health literacy among undergraduate nursing students in China.
Objective: This study aims to understand the levels of digital health literacy among undergraduate nursing students in China and its associated influencing factors.
Methods:Employing a descriptive cross-sectional research design, eligible Chinese nursing undergraduates were surveyed from June to October 2023. The College Students' Digital Health Literacy Scalewas used to assess the digital health literacy levels of undergraduate nursing students in China.
Results: A total of 373 undergraduate nursing students were included. The digital health literacy score was 74.78±8.44, the health lifestyles score was 127.14±11.22, and the psychological resilience score was 79.21±11.02. Pearson correlation analysis results indicated a positive correlation between the digital health literacy of Chinese nursing undergraduates and their health lifestyles and psychological resilience. The results of multiple linear regression analysis showed that volunteer
activity experience, academic performance, physical fitness, psychological traits, health lifestyles and psychological resilience are the influencing factors of digital health literacy of undergraduate nursing students in China (P < 0.05).
Conclusions: The digital health literacy of undergraduate nursing students in China is at a moderate level. There is a correlation between the digital health literacy of nursing undergraduates and their health lifestyles and psychological resilience. Future research should consider interventions in digital health literacy for undergraduate nursing students in China from the perspectives of health lifestyles and psychological resilience.
Impact of climate-smart agriculture on the income and food security of cassava-producing households in the Savalou commune in Benin
Authors: Midjangninou Lyré Sarah Aymar , Bonou Alice , Chogou Sylvain Kpenavoun
Published: July 2024

Climate disruption today represents a threat to the environment and sustainable development. Climate-Smart Agriculture (CSA) is an appropriate adaptation approach to climate change. It allows producers to improve their production and act on their food security, despite the conditions of climate change while limiting the causes arising from agriculture. The objective of this study is to evaluate the impact of CSA, through the use of harvest residues in cassava fields, on the income and food security of cassava producing households in Savalou. The three-stage sampling method made it possible to draw a random sample of 360 cassava producers including 180 users of pigeon pea, mucuna and peanut harvest residues. The average income from cassava production during the last 12 months (until July 2023) is 366,400 FCFA with 387,340 FCFA for beneficiaries compared to 322,060 FCFA for non-beneficiaries. The impact analysis was done with the matching method based on propensity scores. The results of this impact study showed that this adoption contributes to improving income from cassava production by 35,135 FCFA and household food security by 0.10 points, on average per household per year. It would therefore be useful to promote and improve this type of agriculture, in order to ensure sustainable development of the agricultural sector and improve food security.

Published: July 2024

Drought stress and salt stress are serious challenges to crop productivity in the arid lands. This work investigates the impact of NaCl-salt stress and PEG-water stress on germination and embryo growth of two sesame cultivars. The red seeds of Sohg were larger with oblong appearance and lower density relative to the white seeds of Shnd. Seeds were germinated in the dark in isosmotic solutions of NaCl and PEG-6000 at 0, -0.103, -0.205, -0.410 and − 0.615 MPa. The time-based parameters, e.g. velocity, uniformity and synchrony of germination were more reliable measures of germination efficiency than the final germination percentage. The impact of PEG was more severe than that of NaCl particularly on Sohg. The peaks of daily germination percentage were lowered and delayed under stress. The genotypic variability in germinability became evident under stress in favor of Shnd. Radicle length was the most reliable measure of seedling growth but was subjected to stronger impact of NaCl than PEG. Although Na+ mobilization from the seed to the emerging embryo was indifferent in the two cultivars in PEG solutions, Shnd exhibited higher Na+ uptake from NaCl solutions. Whereas K+ mobilization was restricted by NaCl only in Sohg, it was hastened by PEG equally in the two cultivars. The stress-vulnerable cv. (Sohg) recovered with higher magnitude than Shnd, particularly from the more stressing osmoticum (PEG). The indices of germination recovery were highest in PEG-pretreated Sohg while the fresh weight of recovered seedlings was highest in NaCl-pretreated Sohg.

Published: July 2024

Background:
Temporal lobe epilepsy (TLE) is among the most common types of epilepsy and often leads to cognitive, emotional, and psychiatric issues due to the frequent seizures. A notable pathological change related to TLE is hippocampal sclerosis (HS), which is characterized by neuronal loss, gliosis, and an increased neuron fibre density. The mechanisms underlying TLE-HS development remain unclear, but the reactive transcriptomic changes in glial cells and neurons of the hippocampus post-epileptogenesis may provide insights.
Methods:
To induce TLE, 200 nl of kainic acid (KA) was stereotactically injected into the hippocampal CA1 region of mice, followed by a 7-day postinjection period. Single-cell RNA sequencing (ScRNA-seq), single-nucleus RNA sequencing (SnRNA-seq), and Xenium-based spatial transcriptomics analyses were employed to evaluate the changes in mRNA expression in glial cells and neurons.
Results:
From the ScRNA-seq and SnRNA-seq data, 31,390 glial cells and 48,221 neuronal nuclei were identified. Analysis of the differentially expressed genes (DEGs) revealed significant transcriptomic alterations in the hippocampal cells of mice with TLE, affecting hundreds to thousands of mRNAs and their signalling pathways. Enrichment analysis indicated notable activation of stress and inflammatory pathways in the TLE hippocampus, while pathways related to axonal development and neural support were suppressed. Xenium analysis demonstrated the expression of all 247 genes across mouse brain sections, revealing the spatial distributions of their expression in 27 cell types. Integrated analysis of the DEGs identified via the three sequencing techniques revealed that Spp1, Trem2, and Cd68 were upregulated in all glial cell types and in the Xenium data; Penk, Sorcs3, and Plekha2 were upregulated in all neuronal cell types and in the Xenium data; and Tle4 and Sipa1l3 were downregulated in all glial cell types and in the Xenium data.
Conclusion:
In this study, a high-resolution single-cell transcriptomic atlas of the hippocampus in mice with TLE was established, revealing potential intrinsic mechanisms driving TLE-associated inflammatory activation and altered cell interactions. These findings provide valuable insights for further exploration of HS development and epileptogenesis.

Published: July 2024

Purification of crude phosphoric acid manufactured by the wet process from toxic heavy metals such as Iron, zinc, and Manganese is considered to be a very significant environmental and economical procedure. For studying the purification of phosphoric acid, a synthetic solution of 100 ppm from Iron (III), Zinc (II), and Manganese (II) was prepared. The present work aimed to remove Iron (III), Zinc(II), and Manganese(II) from the synthetic liquor by Polyurethane foam (PU) and Charcoal (C) impregnated with di-(2-ethylhexyl) phosphoric acid (D2EHPA) to purify the solution and find out which impregnated sorbent material introduces the best adsorption characters for the presented heavy metals. The results showed that the % Impregnation D2EHPA on C is the highest which equals 56.97% under optimal conditions of impregnation D2EHPA with C and the maximum adsorption capacity was at D2EHPA's concentration of 0.23 Mol/L at contact time 5 hrs, m/v ratio 6g/L and using Benzene as diluents in room temperature. By applying the SIR to remove Iron (III), Zinc(II), and Manganese(II) from a 100 ppm synthetic solution, the results showed that the preferred parameters are pH 3 for Fe, pH 6 for Zn, pH 7 for Mn, time 3h., m/v ratio = 0.05gm/10ml at room temperature. The SIR was effective in removing heavy metals from crude phosphoric acid.
An efficient video slice encryption scheme and its application

With the widespread application of multimedia data in cloud computing environments, ensuring the security and privacy of video content has become a pressing challenge. Traditional encryption methods have limitations; for instance, naive encryption algorithms and selective encryption can protect video content, but they struggle to balance codec compatibility and security. Despite encryption techniques being employed to safeguard video content, concerns persist regarding the security of encrypted videos, especially for highly confidential data. Furthermore, contemporary encryption methods often involve re-encoding and decoding processes, which adversely impact video processing speed. To address this issue, we propose a novel video security encryption scheme that optimally balances encryption speed and security. We introduce a scheme for video fragmentation, design corresponding sorting and merging algorithms, and construct a video transmission framework compatible with this scheme. Secondly, to validate the security of the scheme, we reduce its security to an NP problem and calculate the decryption time complexity, thereby demonstrating its security. Finally, experimental comparisons confirm the efficiency advantage of our scheme in processing large video files. Compared to traditional video encryption techniques, our scheme demonstrates faster overall processing speed and enhanced security when handling large video files.

This paper introduces a novel, compact plasma sterilization system, the Active Plasma Sterilizer (APS), for planetary 9 protection space missions. The development of the APS system is done through iterative testing and design modifications aimed 10 at addressing sterilization modalities for time and temperature, cleaning adhesive surfaces, and cleaning protocols beyond 11 alcohol and bleach. Sterilization testing of Deinococcus radiodurans, Geobacillus stearothermophilus (both spores and non-spores), 12 and Aspergillus fumigatus was verified for the APS on relevant materials of 4 to 5 log reduction up to complete killing in 45 13 minutes or less. The material compatibility testing of the APS performed with Stainless Steel 316, Teflon PTFE, and FR-4 PCB 14 using a single exposure showed no visible material degradation through SEM analysis. This study demonstrates the efficacy of 15 the APS technology for use with planetary protection due to its low-temperature operation, low weight and size, zero-plumbing 16 requirements, safety features, sterilization capabilities, and material compatibility.
Method and Performance of Time Holdover for RT-PPT Receivers Utilizing on-line Estimation of Clock Parameters

Real Time Precise Point Timing (RT-PPT) receivers can achieve sub-nanosecond accuracy through precise clock offset estimation and receiver clock discipline. However, when satellite signals are lost, the receiver clock drifts, causing timing errors due to clock noise and environmental factors. Strict autonomous holdover is therefore essential for high-precision timing receivers. This paper proposes a time holdover method based on online clock modelling. At the timing stage, the frequency bias compared to the time reference is estimated and eliminated by the closed control loop. Meanwhile, the recursive least square algorithm is used to estimate the parameters of the clock temperature and ageing effects online. In the event of signal interruption, the initial frequency bias is reduced by one-step prediction, while the clock offset caused by temperature and ageing is compensated for using the estimated parameters. To verify the validity of the method, real experiments were carried out using an RT-PPT receiver with different types of oscillators. The results show that with the method proposed in this paper, we can achieve holdover accuracy better than 1ns in 1h using a rubidium clock after correcting for the initial frequency bias, with an improvement of more than 67% over the free-running clock. And the holdover accuracy of the receiver using an OCXO after correcting for temperature and ageing is better than 1us in 24h, with a performance improvement of more than 70% over the free-running clock.
AREND: A Faster and Robust Solution for Dynamic LR and QR Factorization
Authors: Zhuang Fenghao , He Huiting , Ye Aiping , Zou Lilan
Published: July 2024

Dynamic LR and QR factorization are fundamental problems that exist widely in the control field. However, the existing solutions under noises are lack of convergence speed and anti-interference ability. To this end, this paper incorporates the advantages of Dynamic-Coefficient Type (DCT) and Integration-Enhance Type (IET) Zeroing Neural Dynamic (ZND), and proposes an Adaptive and Robust-Enhanced Neural Dynamic (AREND). On this basis, a Strategy of Integration-Coupling (SIC) is proposed to address multiple error function problems, improving model stability and application scenarios. This strategy is experimentally proven to be effective and has potential expansion capability. After that, the convergence and robustness of our AREND is theoretically analyzed. Furthermore, the proposed AREND is verified by numerical experiments of low-to-high dimensional factorization in comparison with existing solutions. Finally, the real-time 3-D Angle of Arrival (AoA) localization in multiple high-noise conditions, is validated to the accuracy of the proposed model. Code is available at https://github.com/Alana2a3/AREND-Code-Implementation.
Access to land and nature as health determinants: A qualitative analysis exploring meaningful human-nature relationships among Indigenous youth in central Canada
Authors: Hatala Andrew , Morton Darrien , Deschenes Cindy , Bird-Naytowhow Kelley
Published: July 2024

Background:
Human relationships with and connections to nature and the “land” are a commonly accepted Social Determinant of Health. Greater knowledge about these relationships can inform public health policies and interventions focused on health equity among Indigenous populations. Two research questions were explored: (1) what are the experiences of meaningful human-nature relationships among Indigenous youth within central Canada; and (2) how do these relationships function as a determinant of health and wellness within their lives.
Methods:
Drawing from three community-based participatory research (CBPR) projects within two urban centers in Saskatchewan and Manitoba, the integrated qualitative findings presented here involved 92 interviews with 52 Indigenous youth that occurred over a period of nine years (2014–2023). Informed by “two-eyed seeing,” this analysis combined Indigenous Methodologies and a Constructivist Grounded Theory approach.
Results:
Our integrative analysis revealed three cross-cutting themes about meaningful human-nature relationships: (1) promoting cultural belonging and positive identity; (2) connecting to community and family; and (3) supporting spiritual health and relationships. The experiences of young people also emphasized barriers to land and nature access within their local environments.
Interpretation:
This research suggests that policies, practices, and interventions aimed at strengthening urban Indigenous young peoples’ relationships to and connections with nature and the land can have a positive impact on their health and wellness. Public Health systems and healthcare providers can learn about leveraging the health benefits of human-nature relationships at individual and community levels, and this is particularly vital for those working to advance health equity among Indigenous populations.
Status and Prospects of Molecular Simulations for Drug Discovery
Authors: Verli Hugo , Oostenbrink Chris
Published: July 2024

During the past 30 years, molecular simulations (MS) have become increasingly popular among medicinal chemists, being recognized as a promising tool to reduce drug development costs and timelines while increasing its success. From the refinement of docking experiments during the 1990’s to the contemporary possibility to produce accurate models of ligand intrinsic activity and affinity, the use of simulations in medicinal chemistry has progressed rapidly, becoming an essential tool in modern drug discovery pipelines. However, in spite of their potential, in silico methods and MS have historically been dependent on a tradeoff between computational cost and accuracy, which not uncommonly limits their impacts on drug development. In this context, this review presents a concise and up-to-date summary of the role of MS in medicinal chemistry, and examines its participation in recent advancements of both ligand-based and structure-based drug discovery, free-energy predictions, and model accuracies. In addition to offering a synopsis of the potential benefits of MS on drug discovery, this review intends to aid users to both understand the limitations of computational methods and to design more accurate experiments that, as a consequence, will have an increasing impact on the development of new therapeutics.
