Published: June 2024

The Dongba manuscripts are a unique primitive pictographic writing system that originated among the Naxi people of Lijiang, China, boasting over a thousand years of history. The uniqueness of the Dongba manuscripts stems from their pronounced pictorial and ideographic characteristics. However, the digital preservation and inheritance of Dongba manu manuscripts face multiple challenges, including extracting its rich semantic information, recognizing individual characters, retrieving Dongba manuscripts, and automatically interpreting the meanings of Dongba manuscripts. Developing efficient Dongba character detection technology has become a key research focus, wherein establishing a standardized Dongba detection dataset is crucial for training and evaluating techniques. In this study, we have created a comprehensive Dongba manuscripts detection dataset covering various commonly used Dongba characters and vocabularies. Additionally, we propose a model named STEF. Firstly, the Swin Transformer extracts the complex structures and diverse shapes of Dongba manuscripts’ features. Then, by introducing a Feature Pyramid Enhancement Module, features of different sizes are cascaded to preserve multi-scale information. Subsequently, all features are fused in a FUSION module, resulting in features of various Dongba manuscript styles. Each pixel’s binarisation threshold is dynamically adjusted through a differentiable binarisation operation, accurately distinguishing between foreground Dongba manuscripts and background. Lastly, deformable convolution is introduced, allowing the model to dynamically adjust the convolution kernel’s size and shape based on the Dongba manuscripts’ size, thereby better capturing the detailed information of Dongba characters of different sizes. Experimental results show that STEF achieves a recall rate of 88.88%, a precision rate of 88.65%, and an F-measure of 88.76%, outperforming other text detection algorithms. Visualization experiments demonstrate that STEF performs well in detecting Dongba manuscripts of various sizes, shapes, and styles, especially in blurred handwriting and complex backgrounds.

Published: June 2024

Background

The effects of exercise in patients with breast cancer (BC), has shown some profit, but consistency and magnitude of benefit remains unclear. We aimed to conduct a meta-analysis to assess the benefits of varying types of exercises in patients with BC.

Methods

Literature search was conducted across five electronic databases (MEDLINE, Web of Science, Scopus, Google Scholar and Cochrane) from 1st January 2000 through 19th January 2024. Randomized controlled trials (RCTs) assessing the impact of different types of exercise on outcomes related to fitness and quality of life (QOL) in patients with BC were considered for inclusion. Outcomes of interest included cardiorespiratory fitness (CRF), health-related quality of life (HRQOL), muscle strength, fatigue and physical function. Evaluations were reported as mean differences (MDs) with 95% confidence intervals (CIs) and pooled using random effects model. A p value < 0.05 was considered significant.

Results

Thirty-one relevant articles were included in the final analysis. Exercise intervention did not significantly improved the CRF in patients with BC when compared with control according to treadmill ergometer scale (MD: 4.96; 95%Cl [-2.79, 12.70];P = 0.21), however exercise significantly improved CRF according to cycle ergometer scales (MD 2.07; 95% Cl [1.03, 3.11];P = 0.0001). Physical function was significantly improved as well in exercise group reported by 6-MWT scale (MD 80.72; 95% Cl [55.67, 105.77];P < 0.00001). However, exercise did not significantly improve muscle strength assessed using the hand grip dynamometer (MD 0.55; 95% CI [-1.61, 2.71];P = 0.62), and fatigue assessed using the MFI-20 (MD -0.09; 95% CI [-5.92, 5.74];P = 0.98) and Revised Piper scales (MD -0.26; 95% CI [-1.06, 0.55]P = 0.53). Interestingly, exercise was found to improve HRQOL when assessed using the FACT-B scale (MD 8.57; 95% CI [4.53, 12.61];P < 0.0001) but no significant improvements were noted with the EORTIC QLQ-C30 scale (MD 1.98; 95% CI [-1.43, 5.40];P = 0.25).

Conclusion

Overall exercise significantly improves the HRQOL, CRF and physical function in patients with BC. HRQOL was improved with all exercise types but the effects on CRF vary with cycle versus treadmill ergometer. Exercise failed to improve fatigue-related symptoms and muscle strength. Large RCTs are required to evaluate the effects of exercise in patients with BC in more detail.

Background: Cancer patients are a vulnerable population to COVID-19. COVID-19 mRNA vaccines have shown to decrease hospitalization and death risk from COVID-19 in cancer patients. Concurrent COVID-19 vaccination and immune checkpoint inhibitors (ICIs) use may impact immune-related adverse events (irAEs) synergistically. Limited data exist on how COVID-19 mRNA vaccines affect irAEs in ICI-treated cancer patients, especially those with breakthrough infections. Methods: We retrospectively analyzed adult patients with malignant solid tumors receiving ICIs at a single cancer institute (January 2020 to July 2021). Fully vaccinated status is defined as two consecutive doses of mRNA vaccines (BNT162b2 and mRNA-1273). Patients who were partially vaccinated, fully vaccinated post COVID-19 infection, vaccinated with non-mRNA COVID-19 vaccines, or last visit within 30 days post vaccination were excluded. All COVID-19 infections were confirmed by PCR. In the vaccinated group, only post-vaccination irAEs were considered as events. Results: 443 patients were included in our study, with 251 (56.7%) vaccinated and 192 (43.3%) unvaccinated. The baseline characteristics were similar between the two groups, except for age (vaccinated median 68 years, unvaccinated median 62 years, p=0.004). With a median follow-up of 12 months, incidences of all-grade irAEs (19.1% vs. 20.3%, p=0.72) and severe irAEs (5.6% vs. 4.2%, p=0.66) were comparable between vaccinated and unvaccinated groups. 34 breakthrough COVID-19 infections occurred. In the vaccinated group, a non-significant trend of higher all-grade irAEs incidence was noted in the COVID-19 infected subgroup compared to uninfected subgroup (29.4% vs. 17.5%, p = 0.11). Univariate analysis linked COVID-19 vaccination (OR 1.54, 95% CI 1.01-2.35, p=0.04) and ipilimumab + nivolumab use (OR 5.57, 95% CI 1.79-17.35, p=0.003) to a higher risk of all-grade irAEs in the entire cohort. After multivariate adjustment, ipilimumab + nivolumab use remained the only variable associated with all-grade irAEs (OR 4.95, 95% CI 1.57-15.64, p=0.006). Conclusions: Our study suggests that COVID-19 mRNA vaccines do not increase irAE risk in cancer patients on ICIs. Fully vaccinated patients with breakthrough COVID-19 infections may safely continue ICI treatment without an increased irAE risk. [Table: see text]

Authors: Qian Cheng , Zhao Dan-Dan , Zhong Ming , Zhang Bo , Peng Hao , Wang Wei
Published: June 2024

Network percolation is one of the core topics in network science, especially in understanding and optimizing the robustness of real-world networks. As a powerful tool, the message-passing approach shows unique advantages in characterizing network percolation compared with the mean-field approach. This approach simulates the behavioural response when the network is damaged by transmitting and updating messages between network nodes, thereby accurately assessing the robustness of the network. This paper reviews the progress of message-passing approaches in network percolation on simple networks, multilayer networks and higher-order networks in recent years and discusses the application of this approach in other research fields. Finally, we discuss future research directions around this approach.
Qian Xuan Pounding the Balustrade
Authors: Augustin Birgitta
Published: June 2024

In the late thirteenth century, the poet-painter Qian Xuan 錢選 (style [zi (字)] Shunju 舜举, sobriquets [hao 號] Zhaxi weng 霅溪翁, Yutan 玉潭; ca. 1235–ca. 1307) created a horizontal, multi-colored landscape painting known today as Wang Xizhi Watching Geese and owned by the Metropolitan Museum of Art in New York; a copy of the painting exists in the collection of the National Palace Museum in Taipei. The work depicts a waterside pavilion in which a figure stands with his right hand seemingly resting on the balustrade. This article offers a new interpretation of the painting's scene, and it will argue that the figure's hand on the balustrade is the key to an additional perspective of the painting's artistic statement. It begins by analyzing the painting composition, which includes the artist's inscription, before proceeding to a discussion of balustrade in Song ci-poetry and its significance in Qian Xuan's painting. A closer look at the architecture of the pavilion further reveals that the subject and theme of this painting is that of a dejected Song scholar-poet who laments his country's fate.

Learning Curve Associated With Thoracoscopic Anterior Vertebral Body Tether and Double Anterior Vertebral Body Tether for Idiopathic Scoliosis: Analysis of Three Independent Surgeons
Authors: Lau Darryl , Kurland David B. , Neifert Sean , Pahys Joshua , Samdani Amer , Hwang Steven
Published: June 2024

BACKGROUND AND OBJECTIVES:

Anterior vertebral body tether (VBT) is a fusionless approach to treat idiopathic scoliosis, and surgeons are beginning to implement the technique into current practice. This study aims to evaluate the learning curve for single and double VBT.

METHODS:

A retrospective review of 3 surgeons' first 40 single and 20 double VBT was performed. Skeletally immature patients with idiopathic scoliosis who underwent thoracic (single) or thoracolumbar (double) VBT were included. Thoracic VBT was done via video-assisted thoracoscopic surgery and lumbar VBT through a mini-open retroperitoneal approach. Primary outcomes of interest were operative time, radiation exposure, and radiographic correction. Pooled and individual-surgeon analyses were performed.

RESULTS:

A total of 180 patients were included: 120 single and 60 double. Mean age was 12.7 years, and 87.8% were female. Mean segments tethered was 7.8 in single and 11.0 in double. Mean preoperative thoracic scoliosis was 51.5: single 50.5° and double 53.3°. Mean lumbar scoliosis was 36.4°: single 30.0° and double 49.0°. Average operating time was 276.2 minutes; double VBT was significantly longer (217.3 vs 394.0 minutes, P < .001). Mean blood loss was 198.5 mL, and mean fluoroscopy dose was 73.0 mGy. For single VBT, there was a decrease in operative time (283.3-174.8 minutes, P < .001) and fluoroscopy dose (70.1-53.5 mGy, P = .047) over time. Every 10 cases resulted in a 31.4 minute decrease in operative time (P < .001). There were no intraoperative complications. Single VBT resulted in 54.9% thoracic curve correction. Double VBT achieved 53.0% thoracic and 56.7% lumbar correction. There were no differences in curve correction across the learning curve.

CONCLUSION:

VBT is viable fusionless surgical option for scoliosis. As expected, increased experience resulted in shorter operative time; the threshold for such improvement seems to be 10 cases. Importantly, adequate and consistent curve correction can be achieved at the start of the learning curve while mitigating complications.
Percutaneous Screw Distraction for Anatomic Restoration: Case Series
Authors: Findlay Matthew C. , Tenhoeve Sam A. , Twitchell Spencer , Sherrod Brandon A. , Mahan Mark A.
Published: June 2024

BACKGROUND AND OBJECTIVES:

Percutaneous pedicle screw fixation with distraction reduces morbidity after traumatic thoracolumbar burst fractures; however, there are substantial limitations, particularly for correction of kyphosis. The use of fixed-angle screws may offer improved anatomic restoration, facilitating greater postdistraction vertebral height restoration and spinal canal fragment reduction. We examined the radiographic results of distraction across fixed-angle screws immediately after surgery and in long-term follow-up.

METHODS:

Demographic and clinical characteristics were captured for patients with traumatic thoracolumbar fractures undergoing percutaneous pedicle screw fixation by a single surgeon. Radiographic measurements were collected at predistraction, postdistraction, and long-term follow-up time points. Pairedt-tests, Student'st-tests, Mann–WhitneyUtests, and χ2tests were used to assess data where appropriate.

RESULTS:

The case series included 22 patients (77.3% male; mean age 42.0 ± 18.4 years). Hounsfield density consistent with osteopenia was seen in 13.6% of patients at the time of injury. Sporting injuries and motor vehicle accidents were common (both 31.8%). Most injuries occurred at L1 (45.5%). Upon long-term follow-up, the mean injured-level predistraction cross-sectional area improved from 2.1 to 2.9 cm2(P< .01). Compared with the superadjacent level, the injured-level cross-sectional canal area improved by 28.6% (P< .01). Vertebral body index also improved significantly (18.8° mean change,P< .01). The mean bisegmental Cobb angle improved by 6.2° (P= .01), and injured vertebral body compression decreased by 22.4% (P< .01). Significant improvement in correction was achieved with experience, with final technique yielding superior cross-sectional area (P= .04) and compression ratios (P= .03).

CONCLUSION:

Distraction across fixed-angle percutaneous screw instrumentation systems stabilizes traumatic thoracolumbar burst fractures, corrects deformity, and decompresses the spinal canal. Further comparative research is necessary to demonstrate whether outcomes are different between percutaneous instrumentation vs open fusion for thoracolumbar trauma.
State-dependent dynamics of cuttlefish mantle activity
Authors: Cohen-Bodénès Sophie , Neri Peter
Published: June 2024

Cuttlefish skin is a powerful rendering device, capable of producing extraordinary changes in visual appearance over a broad range of temporal scales. This unique ability is typically associated with camouflage; however, cuttlefish often produce skin patterns that do not appear connected with the surrounding environment, such as fast large-scale fluctuations with wave-like characteristics. Little is known about the functional significance of these dynamic patterns. In this study, we developed novel tools for analyzing pattern dynamics, and demonstrate their utility for detecting changes in feeding state that occur without concomitant changes in sensory stimulation. Under these conditions, we found that the dynamic properties of specific pattern components differ for different feeding states, despite no measurable change in the overall expression of those components. Therefore, these dynamic changes are not detectable by conventional analyses focusing on pattern expression, requiring analytical tools specifically targeted to pattern dynamics.
How Do Omega-3 and Omega-6 Fatty Acids Influence the Development of Common Acne?
Authors: Rogalski Paweł , Pomianek Malwina , Makara Katarzyna , Celarek Victor , Makara Karolina
Published: June 2024

Introduction: Acne is one of the most common skin problems affecting people worldwide, especially young individuals. Despite many years of research into the etiology of acne, its exact causes remain a subject of debate. In recent years, increasing scientific interest has focused on the role of diet in shaping skin health, including the influence of omega-3 and omega-6 fatty acids on the severity of acne symptoms.
Objective: The aim of this study is to review the scientific literature regarding the relationship between a diet rich in omega-3 and omega-6 fatty acids and the reduction of acne. We will analyze available scientific evidence and attempt to determine whether dietary changes to increase the intake of these fatty acids may have a beneficial impact on skin condition and reducing the severity of acne symptoms.
Results: Several studies suggest that a diet rich in omega-3 fatty acids, especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), and relatively low in omega-6 fatty acids may be associated with a reduction in acne severity. Some clinical studies have shown that supplementation with omega-3 fatty acids can lead to a reduction in the number of comedones and inflammatory skin lesions in acne patients.
Conclusions: Our literature review suggests that a diet rich in omega-3 fatty acids and lower in omega-6 fatty acids may be beneficial for individuals struggling with acne. However, further clinical research is needed to confirm these observations and better understand the mechanisms of action of fatty acids on skin health. In the meantime, a balanced diet rich in omega-3-containing foods such as fatty fish, nuts, and seeds is recommended as a potential adjunct to acne treatment.
How to Conclude a Suspended Sports League?
Authors: Hassanzadeh Ali , Hosseini Mojtaba , Turner John G.
Published: June 2024

Problem definition: Professional sports leagues may be suspended because of various reasons, such as the recent coronavirus disease 2019 pandemic. A critical question that the league must address when reopening is how to appropriately select a subset of the remaining games to conclude the season in a shortened time frame. Despite the rich literature on scheduling an entire season starting from a blank slate, concluding an existing season is quite different. Our approach attempts to achieve team rankings similar to those that would have resulted had the season been played out in full. Methodology/results: We propose a data-driven model that exploits predictive and prescriptive analytics to produce a schedule for the remainder of the season composed of a subset of originally scheduled games. Our model introduces novel rankings-based objectives within a stochastic optimization model, whose parameters are first estimated using a predictive model. We introduce a deterministic equivalent reformulation along with a tailored Frank–Wolfe algorithm to efficiently solve our problem as well as a robust counterpart based on min-max regret. We present simulation-based numerical experiments from previous National Basketball Association seasons 2004–2019, and we show that our models are computationally efficient, outperform a greedy benchmark that approximates a nonrankings-based scheduling policy, and produce interpretable results. Managerial implications: Our data-driven decision-making framework may be used to produce a shortened season with 25%–50% fewer games while still producing an end-of-season ranking similar to that of the full season, had it been played.

Association of total bilirubin with depression risk in adults with diabetes: A cross-sectional study
Authors: Ye Man-Li , Wang Jie-Ke
Published: June 2024

BACKGROUND

Individuals with diabetes mellitus are more likely to experience depression, although most patients remain undiagnosed. The relation between total bilirubin and depression has been increasingly discussed, but limited studies have examined the association of total bilirubin with depression risk in adults with diabetes, which warrants attention.

AIM

To investigate the association between total bilirubin levels and the risk of depression in adults with diabetes.

METHODS

The study included adults with diabetes from the National Health and Nutrition Examination Survey 2007-2018. Depression was determined using the Patient Health Questionnaire-9. Multivariable logistic regression, propensity score-matched analysis and restricted cubic spline models were utilized to investigate the association between total bilirubin levels and depression risk in adults with diabetes.

RESULTS

The study included 4758 adults with diabetes, of whom 602 (12.7%) were diagnosed with depression. After adjusting for covariates, we found that diabetic adults with lower total bilirubin levels had a higher risk of depression (OR = 1.230, 95%CI: 1.006-1.503, P = 0.043). This association was further confirmed after propensity score matching (OR = 1.303, 95%CI: 1.034-1.641, P = 0.025). Subgroup analyses showed no significant dependence of age, body mass index, sex, race or hypertension on this association. Restricted cubic spline models displayed an inverted U-shaped association of total bilirubin levels with depression risk within the lower range of total bilirubin levels. The depression risk heightened with the increasing levels of total bilirubin, reaching the highest risk at 6.81 μmol/L and decreasing thereafter.

CONCLUSION

In adults with diabetes, those with lower levels of total bilirubin were more likely to have depressive symptoms. Serum total bilirubin levels may be used as an additional indicator to assess depression risk in adults with diabetes.
Clinical therapeutic effect of self-prescribed Sanhanchushi Tongbi on lumbar disc herniation
Authors: Yao Cheng , He Bin , Zhou Jie , Xie Lin
Published: June 2024

BACKGROUND

Lumbar disc herniation (LDH) commonly occurs during spinal surgery; LDH is on the increase in younger patients and is classified as "paralysis" and "back pain.” Sanhanchushi Tongbi (SPST) is a customized prescription. It disperses cold, relieves pain, removes cold from the meridians and viscera, and treats neuropathic pain. However, few studies have investigated its mechanism of pain relief.

AIM

To observe the clinical therapeutic effects on LDH treated with self-prescribed SPST.

METHODS

A total of 211 patients with LDH syndrome were divided into two groups: 107 patients in the control group were treated with conventional massage combined with traction, and 104 patients in the observation group were treated with a combination of the control regimen and self-prescribed oral SPST. The patients were treated for 4 wk. Indices of traditional Chinese medicine (TCM) syndrome score and serum inflammatory factor levels were measured.

RESULTS

After therapy, the TCM syndrome score in the observation group was significantly lower than that in the control group (P < 0.05). The main symptoms, clinical signs, daily activities, and Japanese Orthopedic Association scores in the observation group were significantly higher than those in the control group after therapy (P < 0.05). The levels of tumor necrosis factor-α, interleukin-6, and C-reactive protein were lower in the observation group than in the control group (P < 0.05). In the observation group, superoxide dismutase levels were significantly higher, whereas malondialdehyde levels were significantly lower, compared with the control group (P < 0.05). The overall efficacy rate in the observation group was 96.15%, which was substantially higher than that in the control group (88.79%; P < 0.05).

CONCLUSION

Self-prescribed SPST can reduce the levels of inflammatory and pain-causing factors as well as lumbar pain in patients with LDH.
Cytokine release syndrome triggered by programmed death 1 blockade (sintilimab) therapy in a psoriasis patient: A case report
Authors: Zhou Ming-Hui , Ye Min-Feng , Zhang Zhen-Xing , Tao Feng , Zhang Yu
Published: June 2024

BACKGROUND

In recent years, immune checkpoint inhibitors (ICIs) have demonstrated remarkable efficacy across diverse malignancies. Notably, in patients with advanced gastric cancer, the use of programmed death 1 (PD-1) blockade has significantly prolonged overall survival, marking a pivotal advancement comparable to the impact of Herceptin over the past two decades. While the therapeutic benefits of ICIs are evident, the increasing use of immunotherapy has led to an increase in immune-related adverse events.

CASE SUMMARY

This article presents the case of a patient with advanced gastric cancer and chronic plaque psoriasis. Following sintilimab therapy, the patient developed severe rashes accompanied by cytokine release syndrome (CRS). Fortunately, effective management was achieved through the administration of glucocorticoid, tocilizumab, and acitretin, which resulted in favorable outcomes.

CONCLUSION

Glucocorticoid and tocilizumab therapy was effective in managing CRS after PD-1 blockade therapy for gastric cancer in a patient with chronic plaque psoriasis.

Highlights

EPIC, SHAW, and DRAINMOD models were evaluated for the simulation of winter hydrology.

Energy-based models can better simulate late-winter and early-spring hydrology under winter conditions.

Effective simulation of soil temperature and soil hydraulics in winters were identified as potential areas of development in temperature-based models.

Abstract. The deterioration of Lake Erie's water quality is one of the major concerns in North America. A considerable percentage of annual phosphorus runoff occurs during the non-growing season in cold agricultural regions such as those in the Great Lakes region. Consequently, without accurate simulation of water flow during cold periods, reliable modeling of sediment and nutrient loads to surface water bodies is not achievable. Three hydrological models (EPIC, SHAW, and DRAINMOD) were evaluated for their capacity to predict winter tile flow and to highlight the significant processes that have a larger effect on runoff simulation at a field site in Southern Ontario, Canada. The SHAW model adequately predicted both soil temperature at 10 cm depth (R2 = 0.95; 2013-2014) and winter tile flow (2012-2014, Nov-Apr; R2 = 0.52; PBIAS = 7; NSE = 0.49). In the case of tile flow, DRAINMOD exhibited comparable results to the SHAW model for the same period (R2 =0.55, PBIAS = -28, NSE = 0.58). EPIC was not able to perform satisfactorily in simulating the tile flow during winter conditions, which was attributed to the model’s erroneous prediction of soil temperature from air temperature. It was determined that energy-based models like DRAINMOD and SHAW can better simulate late-winter and early-spring hydrological conditions. Keywords: Agricultural runoff, Canadian winter hydrology, Hydrological models, Soil temperature, Tile flow.
Investigating Electricity Usage Profile for Residential Consumers in India
Authors: Archana
Published: June 2024

Electricity has become one of the essential needs in modern society. The demand and necessity for electricity have increased with population, trade, and industry, which has resulted in increased stress on the grid. As the development of an electricity storage system is costly, utilities are working on customer segmentation to classify the consumers according to their usage patterns to understand their demand and further develop resources accordingly. In this work, the K-Means clustering algorithm has been applied to a two-year monthly consumption data set (January 2019 to December 2020) of 100 residential consumers from Kutheda village Hamirpur (Himachal Pradesh, India) to visualize the diverse consumption behaviour. It resulted in four different clusters of consumers. It also showed that there is a group having a large number of consumers whose consumption is low and consumption pattern is very less flexible in different seasons. Another group of consumers with high consumption also shows high flexibility in consumption patterns, but their number is less. Also, the winter season shows the highest consumption of electricity and the monsoon season shows the lowest consumption of electricity in this particular region. This analysis will certainly help the electricity provider to make production planning for a different group of consumers in a specific season based on electricity consumption patterns.
Intelligent Energy System and Power Metering Optimization Based on the Energy Plan Model
Authors: Peng Ce , Zeng FanQin , Huang Youpeng , Huang Zhaopeng , Mao Xinming
Published: June 2024

With the national carbon neutrality and carbon peaking policies proposed one after another, this paper proposes intelligent Energy system design and power metering based on the Energy Plan model. In this paper, the Energy PLAN model is proposed as the basic model for energy development planning during the 14th Five-Year Plan period, and the simulation calculation is carried out for the energy system in 2020. The research shows that there is a large gap between the peak and valley of power load, the peak time of power supply and demand does not match, and the response-ability of the energy supply department is poor. Thus, the problems to be solved in the development of energy are determined. In addition, the accuracy of the model is further verified by comparing the actual data with the simulation results of Energy PLAN, and the direction of energy structure reform is determined. By coupling the NSGA-II (Non-dominated Sorting Genetic Algorithms-II) algorithm with the development model, a dual-objective multi-time scale scheduling model is established, which aims at the minimum operating cost and the best energy and environmental benefit coefficient. Secondly, the proposed model is solved using the NSGA-II algorithm. In order to ensure the diversity of solutions and promote the Pareto front approach to the ideal Pareto front, the fuzzy dominance method is used to perform a fast non-dominated sorting of the population, and the maximum satisfaction method is used to select the Pareto optimal compromise solution. Example analysis shows that when the power demand level is L*-L*-L*, the power input under “H-M”, “M-L” and “H-L” scenarios is 106.02 × 103, 102.73 × 103 and 94.2 × 103 GWh, respectively. However, when the power demand level is H*-L*-L*, the power input is always 142.64 × 103 GWh. With the decrease in the transmission rate, the measurement data obtained by the user’s electric acquisition platform becomes less and less, and the performance of state estimation becomes worse. When λ=50%, the proposed model still maintains a high estimation accuracy.

Published: June 2024

Solar-based vehicular electrification is bound to play a vital role in Green House Gas (GHG) emission reduction from conventional transports and supporting the fight against environmental degradation. This paper presents the feasibility of solar-based electric vehicle charging (SEVC) in India, a shift of the transportation sector to renewable energy implementation. Solar-electric vehicles may transform the scenario in the coming future in India on a larger scale. Extensive negative environmental impact is produced by transport activities as it pours out 14% of global GHG emissions. The transportation sector is the second major contributor to pollution in India. Currently, dealers of non-renewable resources like coal, petroleum, etc. are facing a tough time meeting increasing demand. This results in limited resources which are being suppressed by the dealers and producers to meet this need which leads us to an insecure future, having scarcity of minerals and fuel. In this paper, we perform a graphical analysis of fuel consumption in India, the growing demand for green transportation in the Indian market and solar potential in our country. In Feb 2023, India’s government revealed the finding of a 5.9 million tons stockpile of unexplored lithium deposits in the Jammu and Kashmir state. So, the price of batteries would be significantly impacted by this, making EVs more accessible to customers. This paper also includes challenges in adopting solar-based transportation, steps of the Indian Government towards green transportation and recommended policies.
Advancing Sustainable Energy Development: A Study of the Factors Influencing Distributed Photovoltaic Industry in Heilongjiang Province
Authors: Fu Pingping , Yang Honghao
Published: June 2024

In today’s energy industry, the development of clean energy has become a global concern. As an important clean energy technology, photovoltaic power generation (PV) is widely used in various countries and regions, helping to reduce the dependence on traditional fossil energy sources and to reduce greenhouse gas emissions. Existing studies have some shortcomings in terms of factors affecting distributed PV grid-connected capacity. First, previous studies tend to focus on the influence of a single factor on the grid-connected capacity of distributed PV, ignoring the interaction effects among multiple factors. Second, the sample scope in existing studies is relatively narrow, often limited to specific regions or countries, and lacks comprehensive regional comparative analysis. In addition, previous studies often do not fully consider the moderating effect of carbon emission intensity on the influencing factors. Based on the above deficiencies, this study aims to build a regression model by analyzing panel data of central municipalities and provinces including Heilongjiang, Shandong and Beijing over the past three years, and construct an interaction model based on the interaction term. The empirical results show that effective sunshine hours, average feed-in tariff and annual electricity consumption are the main factors affecting the grid-connected capacity of distributed PV with a positive effect. The regional heterogeneity analysis also finds that carbon emission intensity enhances the impact of each factor on distributed PV grid-connected capacity. The regulation effect analysis confirms that the average feed-in tariff and annual electricity consumption have a regulation effect. With the results of this study, we fill the knowledge gaps left by previous studies and provide a new perspective to explore the influencing factors of distributed PV. A deeper understanding of the impact of these factors on distributed PV capacity helps us to better understand and optimize the potential of PV generation. In addition, our findings provide policy makers with recommendations and guidance on how to promote distributed PV generation, thereby contributing to the sustainable development of the clean energy sector.

We present a method to study both static and dynamic phase errors in a phase-only spatial light modulator (SLM) caused by surface irregularities and an imperfect response of each pixel to the applied field. This, in turn, degrades optical reconstruction, particularly in holographic projection applications. The approach uses the Shack-Hartmann wavefront sensor (SHWFS) to measure these errors. A plane wave illuminates the SLM, and the reflected wavefront is measured by the SHWFS and converted into a phase-only computer-generated hologram (CGH). This CGH is displayed on the SLM to compensate for phase errors, which are verified by subsequent wavefront measurements. Experimental results demonstrate the simplicity, robustness to vibration, and real-time capabilities of the SHWFS in contrast to interferometric methods.

Using conical optical fibers, we explore new methods for coupling light to nanophotonic structures operated in constrained environments. With a single-sided conical fiber taper, we demonstrate efficient coupling to an on-chip nanophotonic bus waveguide immersed in a liquid. In the aim of coupling light into a target whispering gallery disk resonator, we then replace such on-chip nanophotonic bus waveguide with two conical fibers joined face to face. This latter approach leads to highly efficient coupling superior to 90% and is shown to be stable within a vibrating pulse tube cryostat operating at low temperatures. It is demonstrated in the telecom band and in the near infrared close to 900 nm of wavelength. Conical fiber methods hence enable reaching the coupling performances required in quantum optics or sensing experiments, even in stringent environments where signal-to-noise had remained a challenge.
