Published: September 2024

Abstract
The application proportion of multi-terminal AC-DC hybrid power distribution systems is constantly increasing. In order to describe the operation status and trajectory of the system and judge whether the system can maintain stable and safe operation, in this paper, the differential algebraic equation is firstly established by mathematical and physical methods for a typical multi-terminal AC-DC hybrid power distribution system. Then, the reachable set in the operation process is analyzed according to the reachability analysis calculation method to judge the stable operation status. An additional damping control method is proposed, which can effectively restrain the negative impedance characteristics of the DC micro-grid and improve the operation stability of the system. Finally, the improvement performance of the control method is verified by combining the reachability analysis results.
Research on secondary power allocation strategy of two types of energy storage units considering dual SOC
Authors: Li Ao , Chen Qigong , Wei Junqiu 
Published: September 2024

Abstract
Against the problem of power fluctuation in the photovoltaic microgrid system, the power fluctuation can be smoothed out by hybrid energy storage technology. Still, the limited capacity of two energy storage units will cause safety problems, such as overcharging and over-discharging in two types of energy storage units and reduce the life of the energy storage device. Therefore, a secondary power distribution control strategy for two types of energy storage units considering dual SOC is proposed. Firstly, the system unbalanced power is calculated. The system unbalanced power is divided through the second-order low-pass filter to obtain the primary distribution power. Then, the SOC of the battery and supercapacitor is divided into nine regions. Finally, the power demand and the SOC in the nine regions are considered simultaneously. Then, the secondary power allocation is carried out for two types of energy storage units. In Matlab/Simulink, the modeling of Photovoltaic microgrids is established, and the simulation results verify the feasibility of the control strategy.

Abstract
This article built the model of concentrated photovoltaic and thermal (CPV/T) systems under the double-axis tracking mode in the east, west, south, and north directions, as well as the single-axis tracking mode in the north and south directions. According to this model, the function of the CPV/T system could be researched. The article established 3D models of large-scale CPV/T systems in different tracking modes and used this model to study the occlusion problem of CPV/T systems. Taking into account cosine loss, edge loss, and occlusion, this paper established energy reception models for different trace modes of the CPV/T system. The energy reception model calculated that the annual energy reception rate of the CPV/T system in the single-axis tracking mode was not a patch on the double-axis tracking CPV/T system. Subsequently, a scaled CPV/T total energy mathematical model was established under these two tracking mods in the article. Combined with the non-steady energy model, the annual total photoelectricity and photothermal output of the CPV/T systems in the single-axis tracking mode and the double-axis tracking mode with an area of 1600 m2 in Xi’an were calculated. The photoelectricity and photothermal outputs of the double-axis tracking mode were 169216 kW·h and 856183 kW·h, respectively. The single-axis tracking node had an annual output of 126898 kW·h for photoelectricity and 637490 kW·h for photothermal.

Abstract
Mariculture will be important to meeting global seafood food demand in the coming decades. Yet, the threat of climate change—such as rising ocean temperatures—on mariculture performance remains uncertain. This is particularly true at small spatial scales relevant to most producers. Additionally, mariculture is often limited by regulations that impose restrictions on production, creating potential hurdles for anticipating and adapting to climate change. We focus on mariculture performance in the United States (U.S.), where state and federal policies and exposure to climate change vary substantially and likely interact. We map a current and future mariculture performance index by combining the first high resolution downscaled (0.083°) climate outputs for U.S. waters, species-specific physiological requirements, and policy restrictions. We find high current performance that will increase under warming oceans, with spatial variation that will amplify existing regional differences. Generally, performance will increase in the north and decrease in the south. While the permitting process is not intentionally climate-forward, permitted species outperformed taxon averages, yet state policies often limit production of seaweeds and finfishes, which perform well. Thus, we sit at a critical juncture where the U.S. could capitalize on its seemingly favorable environmental conditions through re-alignment of regulations to support portfolio diversification to include climate-resilient species.

Published: September 2024

Abstract
The article presents a novel method for hydrocarbon accumulation exploration based on determining the phase components of impedance in environments over hydrocarbons. Experimental studies were conducted at the Rechitsa hydrocarbon field and Osipovichi underground gas storage. The phase characteristics of surface impedance of hydrocarbon accumulation were measured using amplitude-frequency-modulated signals. The results show that determining two components of surface impedance in this mode significantly improves the accuracy of hydrocarbon boundary determination. The developed method can be implemented at frequencies of 0.1-2 GHz, using modulation frequencies of 10-100 MHz, amplitude modulation coefficients of 0.1-1.0, and frequency modulation indices of 20-95. The findings of this research can be applied in electrical exploration for prospecting hydrocarbon accumulation.

Published: September 2024

Abstract
In recent years in Russia, due to the complicated geopolitical situation in some border areas, biogas plants have been considered not only as waste utilization facilities, but also as reserve energy sources, which are safer than traditional - nuclear power plants. In this context, the development of an algorithm for the flexible operation of a biogas plant is particularly relevant, which gives rise to the need to study the stability of the system under the influence of different unfavourable factors. In this work, the influence of long-term storage of cattle manure on its energy potential and biodegradability is studied. The specific methane yield in the test variant with manure stored for 10 months before anaerobic fermentation was 1.41±0.55 ml/g oDM, which is 6.23 times lower than in the test variant with fresh manure; the methane content of manure after long-term storage is 9.66 times lower and the degree of decomposition of its organic matter is 2.72 times lower compared to similar indicators of manure processed without preliminary storage. However, the specific biogas yield from long-term stored manure is 1.66 times higher than the control, which indicates intensive formation of other gases. Thus, long-term storage has a negative impact on the energy potential of cattle manure; if it is necessary to process it in a biogas plant, it is advisable to combine it with more energy-intensive raw materials.

Abstract
The article provides information on the ongoing research on the development of feed preparation and distribution equipment for livestock farms. As a result of scientific analysis, 85% of the livestock and poultry available in livestock farming belong to livestock farms with a small number of livestock, private and family farms. One of the urgent tasks is to create feed preparation and distribution facilities in these small livestock farms. Based on the above, scientific work was carried out to develop a feed distribution device for small livestock farms intended for feeding 20-30 head of cattle. The primary indicators of the feed distribution device’s technical qualities were established, and its technological scheme was developed, based on the results of the research that was done and the needs of the farms. The impact of feed spreader discharge window width and height on feed distribution quality was studied in preliminary research.
Twisting systems and some quantum ℙ³s with point scheme a rank-2 quadric
Authors: Tran Hung , Vancliff Michaela 
Published: September 2024

In 1996, J. J. Zhang introduced the concept of twisting a graded algebra by a twisting system, which generalizes the concept of twisting a graded algebra by an automorphism (the latter concept having been introduced in an article by M. Artin, J. Tate and M. Van den Bergh in 1991). Zhang proved that twisting using a twisting system is an equivalence relation and that certain important algebraic properties are invariant under twisting. We call a twisting system nontrivial if it is not given by an automorphism. However, there are very few examples of nontrivial twisting systems in the literature.

In 1997, the second author and K. Van Rompay and, in 1999, B. Shelton and the second author were successful in finding one example each of a nontrivial twisting system. Their twisting systems were constructed on certain quadratic algebras

Under the Sea: Investigation of Telson Morphology and Cryptic Diversity within Eucopia sculpticauda, a Deep-Sea Lophogastrid from the Gulf of Mexico (Peracarida: Lophogastrida)
Authors: Isma Lys M , Golightly Charles G , Bracken-Grissom Heather D 
Published: September 2024

Synopsis
The field of phylogenetics employs a variety of methods and techniques to study the evolution of life across the planet. Understanding evolutionary relationships is crucial to enriching our understanding of how genes and organisms have evolved throughout time and how they could possibly evolve in the future. Eucopia sculpticauda Faxon, 1893 is a deep-water peracarid in the order Lophogastrida Boas, 1883, which can often be found in high abundances in pelagic trawls. The species can be found along the Mariana Trench, in the Mid-Atlantic Ridge, west Atlantic and east Pacific Oceans, and in the Gulf of Mexico and as deep as 7526 m. Recent collections of E. sculpticauda in the Gulf of Mexico have revealed putative cryptic diversity within the species based on both molecular and morphological evidence. Previous studies have documented two different morphotypes of the telson: the terminal part of the pleon (abdomen) and part of the tail fan. In adults, the morphotypes can be distinguished by lateral constrictions in the telson. This evidence, combined with a previous barcoding study, led to the speculation that telson morphology may be a distinguishing character useful to define cryptic diversity within E. sculpticauda. This study presents additional molecular data from the mitochondrial genes cytochrome c oxidase subunit I, and the large ribosomal subunit (16S), and the nuclear histone 3 gene (H3) to investigate telson morphotypes in relation to evolutionary history within this species. Molecular data identified two strongly supported clades, lending support for potential cryptic diversification within the Gulf of Mexico. Investigations into telson morphology suggest that this character may be informative, but the morphotypes were sometimes ambiguous and additional characters could not be found that discriminate clades. At present, our data suggest early evidence for cryptic diversification within Gulf of Mexico populations, but additional morphological characters and geographic sampling are needed before a new species can be described.

Authors: Laopaiboonkun Sawitree , Chuaychai Aungkana , Yommudee Kanitin , Puttasiri Polawat , Petchluan Siriporn , Thongsutt Tiwaphon 
Published: September 2024

Abstract

Objectives
This study aimed to evaluate the knowledge of community pharmacists toward acute uncomplicated cystitis regarding diagnosis, referral, and conformity to guidelines of the chosen antibiotic and to identify the associated factors with the pharmacist’s knowledge.

Methods
This was a descriptive cross-sectional survey using a questionnaire. Data was collected from 349 community pharmacies in upper southern Thailand between December 2021 and February 2022. Univariate logistic regression analysis was used to assess factors associated with an inappropriate diagnosis of acute uncomplicated cystitis. The variables with P-value &lt; 0.2 were included in the multivariate model. The statistically significant level was set as P-value &lt; 0.05.

Key findings
Three hundred and forty-nine pharmacists from 349 community pharmacies were included. Approximately 65% and 69% of the participants had the knowledge to identify which patients should be considered for cystitis and which patients should be considered for acute uncomplicated cystitis. Ninety eight percentage of pharmacists could select the appropriate antibiotic for uncomplicated cystitis patients. The most prescribed antibiotics were ciprofloxacin (44.7%), norfloxacin (40.7%), and ofloxacin (10.3%). Inappropriate diagnosis was significantly related to age (P = 0.016) and role in the community pharmacy (P = 0.033).

Conclusion
The majority of participants had misconceptions about the differential diagnosis between complicated and uncomplicated cystitis. These were related to the community pharmacists’ advanced age. Continuous pharmacy education should be established to advocate rational antibiotic use, especially in a country where community pharmacists are legally allowed to dispense antimicrobials without a prescription.
Variations in objectively measured sleep parameters in patients with different premature ejaculation syndromes
Authors: Wu Xu , Zhang Yuyang , Jiang Hui , Zhang Xiansheng 
Published: September 2024

Abstract

Background
Poor sleep quality is now a cause of sexual dysfunction.

Aim
To investigate variations in sleep quality among patients with different types of premature ejaculation (PE) and a control group.

Methods
Patients with PE were categorized into groups according to 4 types: lifelong (LPE), acquired (APE), variable (VPE), and subjective (SPE). Basic demographic information about the participants was first collected, and then clinical data were obtained.

Outcomes
Outcomes included the 5-item International Index of Erectile Function, Premature Ejaculation Diagnostic Tool, 7-item Generalized Anxiety Disorder, 9-item Patient Health Questionnaire, Pittsburgh Sleep Quality Index, self-estimated intravaginal ejaculation latency time (minutes), and sleep monitoring parameters obtained from a wearable device (Fitbit Charge 2).

Results
A total of 215 participants were enrolled in the study, of which 136 patients with PE were distributed as follows: LPE (31.62%), APE (42.65%), VPE (10.29%), and SPE (15.44%). Subjective scales showed that patients with APE were accompanied by a higher prevalence of erectile dysfunction, anxiety, and depression, as well as poorer sleep quality (assessed by the Pittsburgh Sleep Quality Index). The results of objective sleep parameters revealed that average durations of sleep onset latency (minutes) and wake after sleep onset (minutes) in patients with APE (mean ± SD; 20.03 ± 9.14, 55 ± 23.15) were significantly higher than those with LPE (15.07 ± 5.19, 45.09 ± 20.14), VPE (13.64 ± 3.73, 38.14 ± 11.53), and SPE (14.81 ± 4.33, 42.86 ± 13.14) and the control group (12.48 ± 3.45, 37.14 ± 15.01; P &lt; .05). The average duration of rapid eye movement (REM; minutes) in patients with APE (71.34 ± 23.18) was significantly lower than that in patients with LPE (79.67 ± 21.53), VPE (85.93 ± 6.93), and SPE (80.86 ± 13.04) and the control group (86.56 ± 11.93; P &lt; .05). Similarly, when compared with the control group, patients with LPE had significantly longer durations of sleep onset latency and wake after sleep onset and a significantly shorter duration of REM sleep.

Clinical Implications
Our study suggests that clinicians should pay attention not only to male physical assessment but also to mental health and sleep quality.

Strengths and Limitations
This study suggests that changes in sleep structure occur in patients with PE, which may provide some direction for future research. However, the cross-sectional study design does not allow us to conclude that sleep is a risk factor for PE.

Conclusion
After controlling for traditional parameters such as age, erectile dysfunction, anxiety, and depression, sleep parameters are independently associated with PE. Patients with APE and LPE show significant alterations in sleep parameters, with patients with APE having notably poorer sleep quality, whereas patients with VPE and SPE have sleep parameters similar to controls.

Published: September 2024

Abstract

Context
Diseases related to excessive sugar consumption have become a public health concern. However, there may be a direct association between the consumption of artificial sweeteners and changes in body weight.

Objective
The aim was to evaluate potential industry financial conflicts of interest in publications on the relationship between high-intensity sweetener consumption and changes in body weight in observational and intervention studies.

Data Sources
The systematic review used the Medline, Embase, Cochrane, Scopus, and the VHL (Virtual Health Library) Regional Portal, including the LILACS databases. The PICOS strategy were used in the search strategy for intervention studies and for observational studies used the exposure factor as the criterion.

Data Extraction
Inclusion criteria were observational and intervention studies in adults, without population or health status restrictions, without restriction on the year of publication, but restricted to full articles in Portuguese, English, and Spanish. Exclusion criteria were humans younger than 18 years, cross-sectional studies, and animal and in vitro studies.

Data Analysis
There were extracted effect estimates, odds ratios, and linear associations, quantifying the effects per unit of intake of high-intensity sweeteners. The risk of bias in the intervention studies was assessed using the Cochrane Collaboration Risk of Bias tool (RoB). The Newcastle Ottawa Scale was used for observational studies (case-control and cohort).

Conclusion
Most clinical trials favor using artificial sweeteners and receive contributions from the food industry. Observational studies, for the most part, show that the use of artificial sweeteners is unfavorable. In these studies, there was no sponsorship from the food industry, only from regulatory bodies. This result suggests that studies that had the support of the food industry had their influence on their outcomes.

Published: September 2024

Abstract
Endometriosis is a chronic gynecological disorder affecting millions of women worldwide, causing chronic pelvic pain, dyspareunia, dysmenorrhea, and infertility, and severely impacting their quality of life. Treatment primarily involves hormonal therapies and surgical excision, but high recurrence rates and the economic burden are substantial. With these challenges, significant discussion surrounds the potential role of dietary patterns in managing endometriosis, making it necessary to bridge this critical gap. This review investigates the current scientific evidence on the dietary patterns (eg, Mediterranean, vegetarian, anti-inflammatory, low-fermentable oligosaccharides, disaccharides, monosaccharides, and polyols [low-FODMAP], and Western-style diets) associated with endometriosis and provides a concise, yet thorough, overview on the subject. In addition, antioxidants, microbiota, and artificial intelligence (AI) and their potential roles were also evaluated as future directions. An electronic-based search was performed in MEDLINE, Embase, Cochrane Library, CINAHL, ClinicalTrials.gov, Scopus, and Web of Science. The current data on the topic indicate that a diet based on the Mediterranean and anti-inflammatory diet pattern, rich in dietary fiber, omega-3 fatty acids, plant-based protein, and vitamins and minerals, has a positive influence on endometriosis, yielding a promising improvement in patient symptoms. Preclinical investigations and clinical trials indicate that dietary antioxidants and gut microbiota modulation present potential new approaches in managing endometriosis. Also, AI may offer a promising avenue to explore how dietary components interact with endometriosis. Ultimately, considering genetic and lifestyle factors, a healthy, balanced, personalized approach to diet may offer valuable insights on the role of diet as a means of symptom improvement, facilitating the utilization of nutrition for the management of endometriosis.
