Overview on topology identiﬁcation technologies for a low-voltage distribution network

: The topology identiﬁcation of low-voltage distribution networks is an important foundation for the intelligence of low-voltage distribution networks. Its accuracy fundamentally determines the eﬀectiveness of functions such as power system state estimation, operational control, optimization planning, and intelligent electricity consumption. The low-voltage distribution network is composed of transformers, lines, and end users. The key task of topology identiﬁcation is to distinguish the connection relationship between distribution transformers, low-voltage lines, and phase sequence with end users, which can be divided into transformer user relationship, line user relationship, and phase user relationship. At present, the main methods of low-voltage network topology identiﬁcation can be divided into signal injection method and data analysis method. The signal injection method requires a large number of additional terminal devices and is diﬃcult to promote. The data analysis method combines the characteristics of switch state, voltage, current, electrical energy, and other data to perform topology analysis. The commonly used methods include correlation analysis and feature learning. Finally, typical problems that urgently need to be solved in topology recognition and representation were proposed, providing a reference for the research and development of low-voltage distribution network topology automatic recognition technology.
Rapid and Gradual Modes of Aerosol Trace Metal Dissolution in Rapid and Gradual Modes of Aerosol Trace Metal Dissolution in Seawater Seawater

Atmospheric deposition is a major source of trace metals in marine surface waters and supplies vital micronutrients to phytoplankton, yet measured aerosol trace metal solubility values are operationally deﬁned, and there are relatively few multi-element studies on aerosol-metal solubility in seawater. Here we measure the solubility of aluminum (Al), cadmium (Cd), cobalt (Co), copper (Cu), iron (Fe), manganese (Mn), nickel (Ni), lead (Pb), and zinc (Zn) from natural aerosol samples in seawater over a 7 days period to (1) evaluate the role of extraction time in trace metal dissolution behavior and (2) explore how the individual dissolution patterns could inﬂuence biota. Dissolution behavior occurs over a continuum ranging from rapid dissolution, in which the majority of soluble metal dissolved immediately upon seawater exposure (Cd and Co in our samples), to gradual dissolution, where metals dissolved slowly over time (Zn, Mn, Cu, and Al in our samples). Additionally, dissolution affected by interactions with particles was observed in which a decline in soluble metal concentration over time occurred (Fe and Pb in our samples). Natural variability in aerosol chemistry between samples can cause metals to display different dissolution kinetics in different samples, and this was particularly evident for Ni, for which samples showed a broad range of dissolution rates. The elemental molar ratio of metals in the bulk aerosols was 23,189Fe: 22,651Al: 445Mn: 348Zn: 71Cu: 48Ni: 23Pb: 9Co: 1Cd, whereas the seawater soluble molar ratio after 7 days of leaching was 11Fe: 620Al: 205Mn: 240Zn: 20Cu: 14Ni: 9Pb: 2Co: 1Cd. The different kinetics and ratios of aerosol metal dissolution have implications for phytoplankton nutrition, and highlight the need for uniﬁed extraction protocols that simulate aerosol metal dissolution in the surface ocean.
Decomposition and Microarthropod Abundance in Litter and Soil in a Southern Appalachian Wetlands Complex

This study examined decomposition and microarthropod abundance in five plant communities, each with varying soil characteristics and anthropogenic disturbance histories, at the Talula Wetland Complex in Graham County, NC. Both litter bags and soil cores were used to measure microarthropod abundance, with extraction performed by a Tullgren-type funnel setup. It was found that the least disturbed plant communities, red maple in particular, have the quickest decomposition, the greatest number of litter microarthropods, the most soil organic carbon, and the lowest soil pH. Positive correlations were shown between soil organic carbon and total litter microarthropods; negative correlations were found between soil pH and total litter microarthropods. No correlation was found between soil moisture and microarthropod abundance, suggesting that moisture levels were adequate throughout our sites. Cores and litter bags showed similar trends in variation by date and ranking by taxa abundance. We conclude that soil characteristics, related to less disturbance, rather than the presence of a closed canopy, are the main influences on decomposition and litter microarthropods. It appears that the most intact ecosystems are functioning at the healthiest levels.
Lipids in Health and Disease

Background: Ezetimibe (Zetia®) is a potent inhibitor of cholesterol absorption that has been approved for the treatment of hypercholesterolemia. Statin, an inhibitor of cholesterol synthesis, is the first-choice drug to reduce low-density lipoprotein-cholesterol (LDL-C) for patients with hypercholesterolemia, due to its strong effect to lower the circulating LDL-C levels. Because a high dose of statins cause concern about rhabdomyolysis, it is sometimes difficult to achieve the guideline-recommended levels of LDL-C in high-risk patients with hypercholesterolemia treated with statin monotherapy. Ezetimibe has been reported to reduce LDL-C safely with both monotherapy and combination therapy with statins. Results: To investigate the effect of ezetimibe as "add-on" therapy to statin on hypercholesterolemia, we examined biomarkers and vascular endothelial function in 14 patients with hypercholesterolemia before and after the 22-week ezetimibe add-on therapy. Ezetimibe addon therapy reduced LDL-C by 24% compared with baseline (p < 0.005), with 13 patients (93%) reaching their LDL cholesterol goals. Of the Ezetimibe add-on therapy significantly improved not only LDL-C, high-density lipoprotein-cholesterol (HDL-C), and apolipoprotein (apo)B levels, but also reduced levels of triglyceride (TG), the ratio of LDL/HDL-C, the ratio of apoB/apoA-I, and a biomarker for oxidative stress (d-ROMs). Furthermore, ezetimibe add-on therapy improved vascular endothelial function in high-risk patients with hypercholesterolemia. Conclusion: In conclusion, ezetimibe as add-on therapy to statin might be a therapeutic good option for high-risk patients with atherosclerosis.

Enhanced Production of Biosurfactant by Pseudomonas aeruginosa Isolate GW-7 under Nitrogen and Phosphate Limiting Conditions

: A novel bacterial strain of Pseudomonas aeruginosa has been isolated and characterized by screening samples from formation water of local oil wells and other habitat, which overproduced potent biosurfactant under phosphate limiting condition within 36 hours of incubation. Biosurfactant producing bacteria were isolated from the oil, formation water and from the soil contaminated with oil from the local oil wells; strains were grown on different medias having different carbon sources. Selected 66% culture reduced surface tension lesser than 33 mN/m and interfacial tension lesser than 3 mN/m whereas 85% showed hemolytic activity. Pseudomonas spp. was most common while some Micrococcus and Acinetobacter were also identified. Most potent biosurfactant producers were P. aeruginosa, P. fluorescens and Micrococcus spp. P. aeruginosa strain GW-7 was selected for further studies. BH-mineral medium was best for biosurfactant production as it reduced surface tension to (32 mN/m), interfacial tension (2.5 mN/m). Other best medium was an inorganic phosphate limited medium containing proteose peptone/glucose/ ammonium salts, as its surface tension and interfacial tension reached to 30 mN/m and 2.5 mN/ m, respectively, after 36 hours. P. aeruginosa isolate GW-7 isolated from oil enriched soils from Gwadar coastal area produced potent biosurfactant (rhamnolipid) in large amount in reasonably short period of time (36 hours) under nitrogen and phosphate limiting conditions.

24 Titles of scientific papers pay a key role in their discovery, and “good” titles engage and 25 recruit readers. A particularly interesting aspect of title construction is the use of humour, but 26 little is known about whether funny titles boost or limit readership and citation of papers. We 27 used a panel of volunteer scorers to assess title humour for 2,439 papers in ecology and 28 evolution, and measured associations between humour scores and subsequent citation (both self-29 citation and citation by others). Papers with funnier titles were cited less often, but this appears to 30 result from a confound with paper importance. Self-citation data suggest that authors give 31 funnier titles to papers they consider less important. After correction for this confound, papers 32 with funny titles have significantly higher citation rates, suggesting that humour recruits readers. 33 We also examined associations between citation rates and several other features of titles. 34 Inclusion of acronyms and taxonomic names was associated with lower citation rates, while 35 assertive-statement phrasing and presence of colons, question marks, and political regions were 36 associated with somewhat higher citation rates. Title length had no effect on citation. Our results 37 suggest that scientists can use creativity with titles without having their work condemned to 38 obscurity. 39 40 41
A protocol for systematic review and meta-analysis

Background: Post-stroke depression (PSD) is one of the most common neuropsychiatric complications after stroke and is associated with increased risk of death and poor functional outcomes. Strong evidence shows that exercise has benefits for depression. However, it is not clear whether exercise has benefits specifically for PSD. This study aims to explore the effects of exercise on PSD and to establish safe and effective exercise prescriptions. Methods and analysis: The PubMed, Cochrane Library and EMBASE, databases will be searched using prespecified search strategies. Randomized controlled trials and non-randomized prospective controlled cohort studies regarding exercise for PSD will be included. The primary outcomes are depression scale and stroke outcome. The secondary outcomes are the occurrence of adverse events, cognitive function, quality of life indices, and the expression of nerve cell factors. The methodological quality of each study will be evaluated by the physiotherapy evidence database scale. The heterogeneity will be evaluated using the I test. If I > 50%, random effects models will be used in the analysis; otherwise, fixed effects models will be used to pool the data. Results: This study will assess the efficacy and safety of exercise for PSD. Conclusions: Our findings will be helpful for clinicians to re-examine the clinical decision-making in the treatment of PSD, by assessing the efficacy of a promising treatment modality for patients with PSD. Ethics anddissemination: Ethical approval is not required because this study is a secondary analysis. The results of this study will be disseminated through journals and academic exchanges. Systematic review registration number: INPLASY202110100. Abbreviations: PEDro = physiotherapy evidence database, PSD = post-stroke depression.
Stream shading, summer streamflow and maximum water temperature following intense wildfire in headwater streams

Adjacent headwater streams were monitored for postfire shade, summer streamflow and maximum water temperature following the 40,000 ha Silver Complex fire in southern Oregon. Average postfire shade (30 percent) for the three streams was considerably less than prefire shade (est.>90 percent). Dramatic increases in direct solar radiation resulted in large but variable increase in maximum water temperature. Increase was greatest in Stream C where temperature increased 10.0°C. Stream B increased 6.2°C. Stream A increased 3.3°C.
Integrative Biology

Synopsis Organisms continuously face environmental fluctuations, and allocation of metabolic investment to meet changing energetic demands is fundamental to survival and reproductive success. Glucocorticoid (GC) hormones (e.g., corticosterone [CORT]) play an important role in energy acquisition and allocation in the face of environmental challenges, partly through mediation of energy metabolism. Although GCs and metabolic rate are expected to covary, surprisingly few empirical studies have demonstrated such relationships, especially in wild animals. Moreover, studies testing for associations between GCs and fitness generally do not account for among-individual differences in energy expenditure or energy allocation. We measured CORT (baseline and stress-induced) and metabolic traits (resting metabolic rate [RMR], cold-induced VO 2max [M sum ], and aerobic scope [the difference between M sum and RMR]) in female tree swallows ( Tachycineta bicolor ) during chick-rearing, and tested for their associations with several variables of reproductive performance. We found a positive relationship be-tween RMR and baseline CORT, but no consistent associations between stress-induced CORT (SI-CORT) and M sum . This suggests that while baseline CORT may be a good indicator of an individual’s baseline metabolic investment, SI-CORT responses are not associated with aerobic scope or the upper limits of aerobic performance. Furthermore, we found that metabolic traits were associated with reproductive performance: females with higher reproductive output showed higher M sum , and also tended to show
Comparison of monkey and human retrosplenial neurocytology

Retrosplenial cortex (RSC) has unique problems for human neuroimaging studies as its divisions are small, at the lower end of functional scanner spatial resolution, and it is buried in the callosal sulcus. The present study sought to define the cytoarchitecture of RSC in human and monkey brains along its entire anteroposterior extent. The results show anterior extensions, a newly defined dichotomy of area 30, a new area p30, and an area p29v in monkey that differentiates into three divisions in human. Accordingly, anterior (a), intermediate (i), and posterior (p) divisions of areas 29l, 29m, 30l, and 30m were identified. Posterior area 29 has higher neuron packing in the granular layer than anterior and intermediate divisions of area 29. A newly detected dysgranular area p30 has larger neurons in layers II–IIIab than a30 and i30 and with substantially higher NFP expression in layer IIIab of posterior areas than areas a30 and i30. Medial area 30 has larger pyramids and higher NFP expression in all layers than area 30l. The new area p30 was seen between areas p29m and p30I in both species. Finally, a ventral area p29v is present in monkeys. This latter area appears to differentiate into three divisions in human with the most extensive granular layer adjacent to layer I in p29vm and p29vl. Functional imaging has identified pRSC as part of a cognitive map which is engaged in spatial navigation and localization of personally relevant objects.
What’s On the Menu? Towards Predicting Nutritional Quality of Food Environments

Unhealthy diets are a leading cause of major chronic diseases including obesity, diabetes, cancer, and heart disease. Food environments--the physical spaces in which people access and consume food--have the potential to profoundly impact diet and related diseases. We take a step towards better understanding the nutritional quality of food environments by developing MINT: Menu Item to NutrienT model. This model utilizes under-studied data sources on recipes and generic food items, along with state-of-the-art word embedding and deep learning methods, to predict the nutrient density of never-before-seen food items using only their name as input. The model achieves an R^2=0.77, a substantial improvement over comparable models. We illustrate the utility of MINT by applying it to the Los Angeles restaurant food environment, and discover close agreement between predicted and ground truth nutrient density of restaurant menu items. This model represents a significant step towards a policy toolkit needed to precisely identify and target food environments characterized by poor nutritional quality.
Comparison of Blood-Based Shotgun and Targeted Metagenomic Sequencing for Microbiological Diagnosis of Infective Endocarditis

Abstract Background Shotgun and targeted metagenomic sequencing have been shown in separate studies to be potentially useful for culture-free pathogen identification in blood and/or plasma of patients with infective endocarditis (IE). However, the 2 approaches have not been directly compared. The aim of this study was to compare shotgun metagenomic sequencing with targeted metagenomic sequencing (tMGS) for organism identification in blood or plasma of patients with IE. Methods Patients with possible or definite IE were prospectively enrolled from October 2020 to July 2021. Shotgun metagenomic sequencing was performed with the Karius test, which uses microbial cell-free DNA (mcfDNA) sequencing to detect, identify, and quantitate DNA-based pathogens in plasma. tMGS was performed using a 16S ribosomal RNA (rRNA) polymerase chain reaction assay targeting the V1 to V3 regions of the 16S rRNA gene. Results were compared using the McNemar test of paired proportions. Results Samples from 34 patients were investigated. The Karius test was positive in 24/34 (71%), including 3/6 (50%) with blood culture–negative endocarditis (BCNE), which was not significantly different from the positivity rate of tMGS (P = .41). Results of the Karius test were concordant with tMGS in 75% of cases. The Karius test detected 2 cases of methicillin-resistant Staphylococcus aureus among the 7 S. aureus detections, in accordance with results of phenotypic susceptibility testing. The combination of blood cultures, the Karius test, and tMGS found a potential causative pathogen in 33/34 (97%), including 5/6 with BCNE. Conclusions The Karius test and tMGS yielded comparable detection rates; however, beyond organism identification, the Karius test generated potentially useful antibiotic resistance data.
Safety of prehospital intravenous bolus dose nitroglycerin in patients with acute pulmonary edema: A 4‐year review

Intravenous nitrates are a primary therapy for hypertensive congestive heart failure (CHF) with acute pulmonary edema (APE) in the hospital setting. Historically, sublingual nitrates are the mainstay of emergency medical services (EMS) pharmacologic therapy for these patients. We aimed to evaluate the safety of prehospital bolus dose intravenous nitroglycerin in patients with APE.

Gluten-Free Diet Compliance in Children With Celiac Disease and Its Effect on Clinical Symptoms: A Retrospective Cohort Study

A gluten-free diet (GFD) is the only scientifically proven treatment for celiac disease (CD). Strict adherence to this diet in children yields excellent results in terms of the clinical symptoms present at the time of diagnosis. Despite the constraints associated with following this diet, it remains the only hope for children with CD to have a better quality of life and life expectancy. Methods: A retrospective descriptive cohort study was carried out on children diagnosed with CD in the pediatrics department of the Hassan II University Hospital in Fez, Morocco. The children were followed up for 18 months, during which time they were seen as outpatients at different frequencies depending on their clinical condition and degree of compliance with the diet. Results: Only half of the diagnosed children continued to follow our structure. Compliance with the gluten-free diet varied from 58.7% (n = 84) of children who strictly followed the GFD to 3.5% (n = 5) of children who never followed the diet. Compliance was significantly correlated with the child's age, with adolescents being the least compliant (p = 0.03). Similarly, a correlation was observed between compliance with the diet and the disappearance of symptoms (p <0.01), the persistence of certain symptoms (p = 0.02), and the occurrence of complications (p = 0.01). The majority of children (87.3%) had their clinical symptoms resolved within a mean delay of 6.4±3.6 months, with a mode of three months. The speed of symptom resolution differed from one symptom to another but remained statistically correlated with the degree of GFD compliance (p = 0.03). Conclusion: Despite the excellent results of a GFD on clinical symptoms in children, the discrepancies observed between compliance and non-compliance call for close follow-up of children with CD to avoid complications and repercussions on the vital prognosis in adulthood.
SCALER: Versatile Multi-Limbed Robot for Free-Climbing in Extreme Terrains

This paper presents SCALER, a versatile free-climbing multi-limbed robot that is designed to achieve tightly coupled simultaneous locomotion and dexterous grasping. Although existing quadruped-limbed robots have shown impressive dexterous skills such as object manipulation, it is essential to balance power-intensive locomotion and dexterous grasping capabilities. We design a torso linkage and a parallel-serial limb to meet such conflicting skills that pose unique challenges in the hardware designs. SCALER employs underactuated two-fingered GOAT grippers that can mechanically adapt and offer 7 modes of grasping, enabling SCALER to traverse extreme terrains with multi-modal grasping strategies. We study the whole-body approach, where SCALER uses its body and limbs to generate additional forces for stable grasping with environments, further enhancing versatility. Furthermore, we improve the GOAT gripper actuation speed to realize more dynamic climbing in a closed-loop control fashion. With these proposed technologies, SCALER can traverse vertical, overhang, upside-down, slippery terrains, and bouldering walls with non-convex-shaped climbing holds under the Earth's gravity.
M\"obius function and primes: an identity factory with applications

We study the sums $\sum_{n\le X, (n,q)=1}\frac{\mu(n)}{n^s}\log^k\left(\frac{X}{n}\right)$, where $k\in\{0,1\}$, $s\in\mathbb{C}$, $\Re s>0$ and give asymptotic estimations in an explicit manner. In order to do so, we produce a large family of arithmetical identities and derive several applications. Along similar ideas, we present an appendix showing the inequality $\sum_{n\le X}\Lambda(n)/n\le \log X$, valid for any $X\geq 1$.
