Correlation knowledge extraction based on data mining for distribution network planning

Traditional distribution network planning relies on the professional knowledge of planners, especially when analyzing the correlations between the problems existing in the network and the crucial influencing factors. The inherent laws reflected by the historical data of the distribution network are ignored, which affects the objectivity of the planning scheme. In this study, to improve the efficiency and accuracy of distribution network planning, the characteristics of distribution network data were extracted using a data-mining technique, and correlation knowledge of existing problems in the network was obtained. A data-mining model based on correlation rules was established. The inputs of the model were the electrical characteristic indices screened using the gray correlation method. The Apriori algorithm was used to extract correlation knowledge from the operational data of the distribution network and obtain strong correlation rules. Degree of promotion and chi-square tests were used to verify the rationality of the strong correlation rules of the model output. In this study, the correlation relationship between heavy load or overload problems of distribution network feeders in different regions and related characteristic indices was determined, and the confidence of the correlation rules was obtained. These results can provide an effective basis for the formulation of a distribution network planning scheme.

Theoretical analysis of surface waves in piezoelectric medium with periodic shunting circuits

The investigations of surface waves in the piezoelectric medium bring out great possibility in designing smart surface acoustic wave (SAW) devices. It is important to study the dispersion properties and manipulation mechanism of surface waves in the semi-infinite piezoelectric medium connected with periodic arrangement of shunting circuits. In this study, the extended Stroh formalism is developed to theoretically analyze the dispersion relations of surface waves under different external circuits. The band structures of both the Rayleigh wave and the Bleustein-Gulyaev (BG) wave can be determined and manipulated with proper electrical boundary conditions. Furthermore, the electromechanical coupling effects on the band structures of surface waves are discussed to figure out the manipulation mechanism of adjusting electric circuit. The results indicate that the proposed method can explain the propagation behaviors of surface waves under the periodic electrical boundary conditions, and can provide an important theoretical guidance for designing novel SAW devices and exploring extensive applications in practice.

A case report of intramyocardial dissecting hematoma: a challenging diagnosis

Intramyocardial dissecting hematoma (IDH) is an uncommon complication of myocardial infarction that can potentially lead to cardiac rupture. Two distinguishable types of cardiac rupture have been identified: a simple tear, which is the most common case and is characterized by a lineal or tortuous tear along the myocardial wall, and complex hemorrhagic dissection. IDH is generally classified as complex hemorrhagic dissection, in which blood infiltrates into the myocardial wall. IDH is characterized by a serpiginous tract within the myocardium, which is also known as subepicardial aneurysm. The mechanisms of IDH are multifactorial and contribute to the rupture of intramyocardial vessels, diminished tensile strength of the infarcted myocardium, abrupt increases in perfusion pressure during the perfusion phase, or in rare cases, iatrogenesis. Furthermore, the anatomical substrate of IDH is the spiral helical structure of the heart that favors hemorrhage spreading along the spiral myocardial fibers. IDH is often a challenging diagnosis and prone to misdiagnosis because of its rarity and various clinical presentations. Here, we report a patient with IDH.
Progressive eschar-like wound and peripheral neurological dysfunction with severe inflammatory status: infection or unnatural immune response?

The immune system plays an essential role in maintaining health, protecting humans from pathogens and preventing the majority of tumors. Immunocompromised individuals are more likely to encounter infectious and neoplastic diseases. Excessive immune responses, which are also involved in the pathogenesis of many diseases, have drawn increasing attention in recent years. Blood and nervous system manifestations have been reported to be related to some specific viruses, and potential associations of these viruses with autoimmune diseases have come into the spotlight. Certain infections might arouse immune overreaction in susceptible individuals or even cytokine storms that are harmful to organs and tissues.
Jasmonic acid-mediated stress responses share the molecular mechanism underlying male sterility induced by deficiency of ZmMs33 in maize

Plant male reproduction is a fine-tuned developmental process that is susceptible to stressful environments and influences crop grain yields. Phytohormone signaling functions in control of plant normal growth and development as well as in response to external stresses, but the interaction or crosstalk among phytohormone signaling, stress response, and male reproduction in plants remains poorly understood. Cross-species comparison among 514 stress-response transcriptomic libraries revealed that ms33- 6038, a genic male sterile mutant deficient in the ZmMs33/ZmGPAT6 gene, displayed an excessive drought stress-like transcriptional reprogramming in anthers triggered mainly by disturbed jasmonic acid (JA) homeostasis. An increased level of JA appeared in ZmMs33-deficient anthers at both meiotic and postmeiotic stages and activated genes involved in JA biosynthesis and signaling as well as genes functioning in JA-mediated drought response. Excessive accumulation of JA elevated expression level of a gene encoding a WRKY transcription factor that activated the ZmMs33 promoter. These findings reveal a feedback loop of ZmMs33-JA-WRKY-ZmMs33 in controlling male sterility and JA-mediated stress response in maize, shedding light on the crosstalk of stress response and male sterility mediated by phytohormone homeostasis and signaling.
PtNi-W/C with Atomically Dispersed Tungsten Sites Toward Boosted ORR in Proton Exchange Membrane Fuel Cell Devices

The performance of proton exchange membrane fuel cells is heavily dependent on the microstructure of electrode catalyst especially at low catalyst loadings. This work shows a hybrid electrocatalyst consisting of PtNi-W alloy nanocrystals loaded on carbon surface with atomically dispersed W sites by a two-step straightforward method. Single-atomic W can be found on the carbon surface, which can form protonic acid sites and establish an extended proton transport network at the catalyst surface. When implemented in membrane electrode assembly as cathode at ultra-low loading of 0.05 mgPt cm- 2, the peak power density of the cell is enhanced by 64.4% compared to that with the commercial Pt/C catalyst. The theoretical calculation suggests that the single-atomic W possesses a favorable energetics toward the formation of *OOH whereby the intermediates can be efficiently converted and further reduced to water, revealing a interfacial cascade catalysis facilitated by the single-atomic W. This work highlights a novel functional hybrid electrocatalyst design from the atomic level that enables to solve the bottle-neck issues at device level.
Towards Practical Application of Li-S Battery with High Sulfur Loading and Lean Electrolyte: Will Carbon-Based Hosts Win This Race?

As the need for high-energy-density batteries continues to grow, lithium-sulfur (Li-S) batteries have become a highly promising next-generation energy solution due to their low cost and exceptional energy density compared to commercially available Li-ion batteries. Research into carbon-based sulfur hosts for Li-S batteries has been ongoing for over two decades, leading to a significant number of publications and patents. However, the commercialization of Li-S batteries has yet to be realized. This can be attributed, in part, to the instability of the Li metal anode. However, even when considering just the cathode side, there is still no consensus on whether carbon-based hosts will prove to be the best sulfur hosts for the industrialization of Li-S batteries. Recently, there has been controversy surrounding the use of carbon-based materials as the ideal sulfur hosts for practical applications of Li-S batteries under high sulfur loading and lean electrolyte conditions. To address this question, it is important to review the results of research into carbon-based hosts, assess their strengths and weaknesses, and provide a clear perspective. This review systematically evaluates the merits and mechanisms of various strategies for developing carbon-based host materials for high sulfur loading and lean electrolyte conditions. The review covers structural design and functional optimization strategies in detail, providing a comprehensive understanding of the development of sulfur hosts. The review also describes the use of efficient machine learning methods for investigating Li-S batteries. Finally, the outlook section lists and discusses current trends, challenges, and uncertainties surrounding carbon-based hosts, and concludes by presenting our standpoint and perspective on the subject.

Developing nonlinear additive tree crown width models based on decomposed competition index and tree variables

Crown development is closely related to the biomass and growth rate of the tree and its width (CW) is an important covariable in growth and yield models and in forest management.To date,various CW models have been proposed.However,limited studies have explicitly focused on additive and inherent correlation of crown components and total CW as well as the influence of competition on crown radius from the corresponding direction.In this study,two model systems were used,i.e.,aggregation method system (AMS) and disaggregation method system (DMS),to develop crown width additive model systems.For calculating spatially explicit competition index (CI),four neighbor tree selection methods were evaluated.CI was decomposed into four cardinal directions and added into the model systems.Results show that the power model form was more proper for our data to fit CW growth.For each crown radius and total CW,height to the diameter at breast height (HDR) and basal area of trees larger than the subject tree (BAL) significantly contributed to the increase of prediction accuracy.The 3-m fixed radius was optimal among the four neighborhoods selection ways.After adding decomposed competition Hegyi index into model systems AMS and DMS,the prediction accuracy improved.Of the model systems evaluated,AMS based on decomposed CI provided the best performance as well as the inherent correlation and additivity properties.Our study highlighted the importance of decomposed CI in tree CW modelling for additive model systems.This study focused on methodology and could be applied to other species or stands.
Efficacy of stepwise mini-incision microdissection testicular sperm extraction for nonobstructive azoospermia with varied etiologies

Stepwise mini-incision microdissection testicular sperm extraction (mTESE) is a procedure that attempts to minimize testicular damage. However, the mini-incision approach may vary in patients with different etiologies. Here, we performed a retrospective analysis of 665 men with nonobstructive azoospermia (NOA) who underwent stepwise mini-incision mTESE (Group 1) and 365 men who underwent standard mTESE (Group 2). The results showed that the operation time (mean ± standard deviation) for patients with successful sperm retrieval in Group 1 (64.0 ± 26.6 min) was significantly shorter than that in Group 2 (80.2 ± 31.3 min), with P<0.001. The total sperm retrieval rate (SRR) was 23.1% in our study, and there was no significant difference between Group 1 and Group 2 (P>0.05), even when the etiologies of NOA were taken into consideration. The results of consecutive multivariate logistic regression analysis (odds ratio [OR]: 0.57; 95% confidence interval [CI]: 0.38-0.87; P=0.009) and receiver operating characteristic (ROC) analysis (area under the ROC curve [AUC]=0.628) showed that preoperative anti-Mullerian hormone (AMH) level in idiopathic NOA patients was a potential predictor for surgical outcomes after initial three small incisions made in the equatorial region without sperm examined under an operating microscope (Steps 2-4). In conclusion, stepwise mini-incision mTESE is a useful technique for NOA patients, with comparable SRR, less surgical invasiveness, and shorter operation time compared with the standard approach. Low AMH levels may predict successful sperm retrieval in idiopathic patients even after a failed initial mini-incision procedure.
Pudendal nerve lesions in young men with erectile dysfunction: imaging with 3T magnetic resonance neurography

Erectile dysfunction (ED) is a major health problem worldwide that reduces the quality of life of many families. ED is recognized as a consistent or recurrent inability to achieve and/or maintain a penile erection sufficient for sexual satisfaction. Epidemiological data have shown that ED is associated with increasing age.2 Nevertheless, the prevalence of ED is increasing in younger men (<40 years of age), with previous estimates as high as 30%. More recent studies have also reported organic causes in 5%-72% of ED patients <40 years old, and suggested involvement of the pudendal nerve (PN) as primary cause. The aim of this study was to evaluate the clinical utility of magnetic resonance neurography (MRN) for visualizing and quantifying PN changes in young men with ED.
Recent advances of ferro-/piezoelectric polarization effect for dendrite-free metal anodes

Metal anodes based on plating/stripping electrochemistry, for instance, common alkaline metal lithium (Li), sodium (Na), potassium (K), polyvalent metal magnesium (Mg), aluminum (Al), calcium (Ca) and zinc (Zn) are imminently evoked and increasingly researched for future generation high-energy-density rechargeable batteries due to their large theoretical capacity, low electrochemical potential, and superior electronic conductivity in recent years. However, the uncontrolled dendrite formation issue induces low Coulombic efficiency, short lifespan, and hazardous security risks, hindering the actual applications of metal batteries. Among various solutions, the utilization of ferro-/ piezoelectric materials for metal anodes displays active effects on decreasing local current density, suppressing dendrite growth, and tolerating volume expansion benefits from the unique ferro-/piezoelectric polarization effect. This review presents the research progress of ferro-/piezoelectric polarization effect for regulating the dendritic growth of metal anodes for the first time. First, the current challenges and strategies of metal anodes are proposed. Then, ferro-/ piezoelectric materials and their working principle are discussed. Finally, the recent research progress of ferroelectric and piezoelectric materials on dynamic regulation of dendrite growth is summarized, and the future perspectives are prospected. We hope this review could draw more attention in designing metal anodes with self-polarization materials and promoting their practical applications.
High-efficiency dielectric capacitors based on BaTi_(0.5)Hf_(0.5)O_3 films

Film dielectric capacitors enabled with large breakdown field strength and high energy density play a key role for compact and integrated power systems. Nevertheless, the energy storage efficiency is always sacrificed as we tried to increase the energy density. This trade-off between energy density and efficiency means significant energy dissipation and thermal effects, which will lead to a deterioration of the reliability and lifetime of the dielectric capacitors. In the present work, we design a crystalline-amorphous structure based on BaTi_(0.5)Hf_(0.5)O_3 films, in which the nanosized crystalline BaTi_(0.5)Hf_(0.5)O_3 matrix contributes to a relatively large polarization, while the amorphous phase is beneficial to the enhanced breakdown field strength and lowered polarization-electric field hysteresis. Thus, such structure simultaneously leads to a high energy storage efficiency of 90.6% and a relatively high energy density of 53 J·cm~(-3), as well as excellent antifatigue properties. This work provides a feasible route to realize outstanding energy storage performance in dielectric capacitors.
Template sacrificial controlled synthesis of hierarchical nanoporous carbon@NiCo_2S_4 microspheres for highperformance hybrid supercapacitors

Binary transition metal sulfides are hotly investigated in advanced energy storage devices because of their ultra-high reversible capacity. Nevertheless, the unsatisfied rate capability and cycling stability still hinder their practical application. Herein, hierarchical nanoporous carbon@NiCo_2S_4 (HNCMs@NCS) composites with core- shell flower-like structures were prepared by in situ growing of NiCo_2S_4 nanosheets on HNCMs through a hydrothermal-assisted template sacrificial method. Benefiting from a synergistic effect between the NiCo_2S_4 shell with high specific capacity and the HNCMs with unique porous structure, the synthesized flower-like HNCMs@NCS composites exhibit extraordinary electrochemical performances, including a high capacity of 346.9 mAh·g~(-1) at 1 A·g~(-1), superb rate property with 86.4% initial capacity at 30 A·g~(-1) and predominant cycle stability with 81.2% capacity retention after 5000 cycles. Furthermore, the resulting HNCMs@NCS cathode was coupled with the chemical-activated HNCMs (AHNCMs) anode to construct a hybrid supercapacitor device. The asfabricated device exhibits superior energy density (49.9 Wh·kg~(-1) at 802 W·kg~(-1)) and ultra-high power density (24 kW·kg~(-1) at 29.5 Wh·kg~(-1)). This fascinating result further demonstrates the tremendous prospect of the synthesized HNCMs@NCS composites as high-performance supercapacitor electrode materials.
Modeling uncertainties of reservoir flushing simulations

Every dam or barrage construction affects the watercourse and the retention of sediment that previously was carried by the river, which can lead to siltation of the reservoir and obstruction of water intakes over time, reducing their capacities. However, the information available regarding the effect of sediment and drawdown parameters, sediment management at reservoirs, as well as different equational approaches, is scarce. The current research aims to evaluate the effect of parameters associated with numerical modeling of sediment management in reservoirs considering scenarios with different drawdowns, transport equations, sediment size distributions, and thickness of the initial sediment layer. The case study of the Aimores Hydropower Plant (HPP) is used, applying the Delft3D-FLOW model for twodimensional modeling. All parameters influenced the volume of mobilized sediment, among which the initial layer thickness was the parameter that resulted in the greatest changes in simulated results. In general, the results show that the uncertainties in the input parameters outweigh the uncertainties between the techniques, which found large variations in results when evaluating the use of different transport equations. These results indicate the importance of proper estimation of model parameters for predicting effects with accuracy and the need for such studies before planning and management operations are evaluated to avoid environmental harm and energy waste.
