Semi-physical simulation-driven contrastive decoupling net for intelligent fault diagnosis of unseen machines under varying speed

Multi-source domain generalization provides a good idea for intelligent fault diagnosis of unseen machines. However, the acquisition of multi-source training sets would not only affect the generalization effect, but also cause huge economic loss. Too much difference between source training sets would lead to negative transfer, while too much similarity between the sets would cause zero transfer. Simultaneously, the current methods based on the assumption of stable speed cannot realize intelligent diagnosis under varying speed. Therefore, a semi-physical simulation-driven contrastive decoupling network is presented. First, a phenomenological model is used to generate large amount of simulation data with different modulation frequencies and signal-to-noise ratios to provide support for the training of the net. Next, with the joint help of simulation data and physical data, a contrastive framework is introduced to extract domain-independent features. Finally, a decoupling framework is proposed to minimize speed-related information while maximizing health-related features, thereby enabling intelligent diagnosis of unseen devices at varying speed. The proposed method is tested on two cases operating under sharp speed variation and compared with some state-of-the-art methods. The results show the superiority of the proposed net in intelligent diagnosis of unseen equipment under drastically varying speed.

From the Idea to the Business Plan: Evaluating the Opportunity

The purpose of a business plan is to explain a story, the story of our project, and this story is essential to find out if our initiative is something more than just a good idea. In order to come to fruition it should also be an opportunity. An opportunity is the conviction that this idea can be carried out because a possible market exists to make it happen. The business plan is the basic tool that entrepreneurs in the health sector need to transform their idea into an opportunity and make it happen. Evaluating the opportunity is the first step in the process.

Rapid identification of Radix Astragali origin by using fluorescence probe combined with chemometrics

Fluorescent probes for metal ion recognition can be divided into selective probes, weakly selective probes, and non-selective probes roughly. Weakly selective probes are not often used for quantitative analysis of metal ions due to their overlapping spectra resulting from simultaneous interactions with multiple metal ions. Conversely, the different metal ions contained in herbal medicine extracts from different geographical origins will produce corresponding fluorescence fingerprint profiles after interaction with weakly selective fluorescence probes. The performance can be used in the study of origin tracing of food or Chinese herbal medicine. Weakly selective fluorescent probes of benzimidazole derivatives have been synthesized and attempted to be used in the origin tracing of Radix Astragali in this work. Radix Astragali from different origins will produce different fluorescence fingerprint spectra due to the difference of metal ions and content in combination with the probe. Excitation-emission matrix (EEM) fluorescence spectroscopy in conjunction with N-way partial least squares discriminant analysis (N-PLS-DA), and unfolded partial least squares discriminant analysis (U-PLS-DA) were used to identify the origin of 150 Radix Astragali samples from five geographical origins. The prediction results showed that the correct recognition rates of the U-PLS-DA model and N-PLS-DA model are 95.92% and 93.88%, respectively. In comparison, the results of U-PLS-DA are slightly better than those of N-PLS-DA. These findings indicate that EEM fluorescence spectroscopy based on weakly selective fluorescent probes combined with multi-way chemometrics provides a good idea for the origin tracing of traditional Chinese medicine.

Navigating the Halal Frontier: The Legality of Cryptocurrency in Islamic Finance

The popularity of virtual currencies has expanded dramatically in recent years. Seminars and conferences have been held to discuss the nature and feasibility of cryptocurrencies. Some argue that having a replacement for the current fiat currency system is a good idea since it does not need a bank account, tax payments, or audits, as cryptocurrencies do. Others argue that any means of payment other than the commonly recognised ones, such as cash, checks, DD, and so on, would allow for tax and audit evasion, which would have a huge detrimental impact on the government budget and the economy. The convergence of cryptocurrencies and Islamic finance has caused much controversy among the Muslim community about whether cryptocurrency transactions are permissible (halal) or prohibited (haram). This study investigates Islamic finance concepts as well as the technological and economic elements of cryptocurrencies in order to assess their conformity with Sharia law. It was found that cryptocurrencies are not Halal in Islam because they lack inherent value and are susceptible to additional regulatory oversight.

Is it a good idea to select green logistics to enhance environmental sustainability? Insights from global sample

ABSTRACT This research attempts to empirically examine the effects of green logistics on environmental sustainability by investigating the nexus between green logistics (GL) and environmental sustainability (ES) by applying varied econometric methodologies to an international sample of 44 nations during the 2006–2021 period. The estimation outcomes show that the size of GL has a positive effect on both indexes. We find robust consequences using numerous econometric methods and including additional explanatory factors. To throw light on the nexus between GLPI and variables, we show the impacts of GL on ES both in the short and long term and compare the effect of GL on ES. The findings suggest that the nexus between GL and ES tends to appear in the long run. In particular, we find that the impacts of GL become more acknowledged in a nation described by a high industrialisation level.

The Exponential-based Carbon Credit Cap in Carbon Cap-and-Trade Markets

The concept of carbon markets as developed in 1997 by the Kyoto Protocol was a good idea whose adoption and implementation by all counties and states would have significantly reduced the rate of emission of greenhouse gases into the atmosphere. The Carbon markets were proposed to be based on cap-and-trade whose forces of supply and demand would discourage the increase or steady emission of greenhouse gases and force companies to, gradually, revert to the use of clean energy in production. This would promote the net zero carbon emission target. The carbon markets were designed to have a cap whose nature is a specific number for all entities. The number represents the carbon quantity whose regulator would keep reducing until the net zero carbon is achieved. This nature of the cap encourages large emitters of greenhouse gases to shift to other jurisdictions that have soft regulations. It also encourages restructuring into smaller companies whose net emissions could be almost the same or more than before. In this paper, we have proposed an exponential-based cap that would leave little or no room for such market strategies. We have also demonstrated how the proposed cap can be implemented.

Substituting Low-Calorie Sweetened Beverages for Sugar-Sweetened Beverages to Prevent Obesity and Cardiometabolic Diseases: Still a Good Idea?

In this Perspective, we highlight the recent findings from observational and interventional studies, focusing on obesity, gut microbiome, and cardiometabolic health. We provide public health actors and health care professionals with an insightful overview of recent evidence to bridge the gap between research and practice.

Strategies for the biological synthesis of D-glucuronic acid and its derivatives.

D-glucuronic acid is a kind of glucose derivative, which has excellent properties such as anti-oxidation, treatment of liver disease and hyperlipidemia, and has been widely used in medicine, cosmetics, food and other fields. The traditional production methods of D-glucuronic acid mainly include natural extraction and chemical synthesis, which can no longer meet the growing market demand. The production of D-glucuronic acid by biocatalysis has become a promising alternative method because of its high efficiency and environmental friendliness. This review describes different production methods of D-glucuronic acid, including single enzyme catalysis, multi-enzyme cascade, whole cell catalysis and co-culture, as well as the intervention of some special catalysts. In addition, some feasible enzyme engineering strategies are provided, including the application of enzyme immobilized scaffold, enzyme mutation and high-throughput screening, which provide good ideas for the research of D-glucuronic acid biocatalysis.

Start of the year marks a good time to revisit expense reimbursements

Now that most—if not all—nonprofit boards are back to holding their regular board meetings in person, it's a good idea for them to refresh their policies regarding expense reimbursement.

Is Trusting Your Gut a Good Idea? Implications from The Emotional Mind

What exactly does it mean to “trust your gut”? What use are gut-level insights when a person is attempting to consciously and deliberately navigate life altering decisions, such as those surrounding marriage, divorce, job changes, home buying, etc.? This essay provides a partial answer to those questions by leveraging the account of “emotional bodily feelings” offered in Tom Cochrane’s The Emotional Mind: A Control Theory of Affective States. This essay shows why “trusting your gut” is a reasonably good path to emotional self-awareness in decision-making. The first half of the essay offers an analysis of what many people mean by the colloquial advice to “trust your gut,” at least when they deploy that advice in context of an ongoing dialogue about a friend or family member’s major life-decision. In the second half, this article briefly summarizes Cochrane’s account of emotions and emotional bodily feelings, and spells out how these concepts might be deployed to understand the advice to “trust your gut” as nearly tantamount to saying “pursue emotional self-awareness.”

Impacts of authentic texts on EFL students' reading comprehension

The purpose of this research was to explore the effect of authentic texts on students' reading comprehension of the English Education Study Program at the University of Bengkulu. This research applied a quantitative method, in the form of a quasi-experimental study. The subjects of the research were 68 sixth-semester students in which 34 students as the experimental group and 34 other students as the controlled group. The experimental group got treatment of authentic text, while the controlled group got treatment of textbooks. The instrument of the research used was the test. The mean score of the experimental group was higher than the scores of the controlled group (75.88: 68.24). The t-test calculation = (p<α); (0.005<0.05). It means alternative hypothesis was accepted, and null hypothesis was rejected. In other words, there was an effect of using authentic texts on students’ reading comprehension. It was recommended that it was a good idea for English lecturers, apart from other texts, pay close attention to authentic texts as well.

Examining the Social Costs of Carbon Emissions and the Ecosystem Service Value in Island Ecosystems: An Analysis of the Zhoushan Archipelago

Assessments of the ecosystem service value (ESV) and the social cost of carbon (SCC) inform national and government management decisions in the areas of human well-being and climate change mitigation and adaptation, respectively. Studying the correlation between the two provides a theoretical basis for low-carbon and high-quality regional development, achieving economic decarbonization, and improving human well-being. In this study, we take Zhoushan Archipelago as a case study, consider the ESV and SCC in Zhoushan Archipelago during the period 2010–2020, analyze their spatial development characteristics, and analyze the correlation between the two in time and space. The findings indicate that, with only a 1.5% change, the overall ESV in the Zhoushan Archipelago fell between 2010 and 2020. Conversely, there was a 1604.01 × 104 t increase in net carbon emissions and a quick 2452% increase in SCC. During the study period, a substantial positive association was found between ESV and SCC in the Zhoushan Archipelago, according to the global spatial correlation analysis of the two variables. It passed the test for p-value. This study presents a new potential way to solve the environmental and economic difficulties caused by climate change by providing a mechanism for quantitatively assessing the environment from the perspective of monetary worth. In order to improve the ecological security pattern and ease the burden of regional carbon emissions, it is vital to make use of regional advantages, maintain forests, and develop blue-carbon resources such as mudflats. It is a good idea to cooperate regionally with nearby metropolitan agglomerations. The study’s findings are crucial for advancing sustainable development planning in the Zhoushan Archipelago, both theoretically and practically.

Discussing The White-Haired Girl Opera and Ballet from the Perspective of Female Characters

 The scope of this dissertation is to study the female protagonist, Hei'er, in the White Hairy Maiden Opera and Ballet and to exemplify the historical context of the White Hairy Maiden Opera and Ballet and the characteristics of the status of women in this era. The purpose of the research is to draw the characteristics of the era of the female characters in Bai Mao Nü in relation to the female lead's plot and the women's characteristics of the era in the context of Chinese history. The writing process of the thesis is firstly to find the tableaux and scores of the White Hairy Woman's operas and dance dramas in Chinese websites for reading and to collect the literature related to the White Hairy Woman's operas and dance dramas, and to collect the literature on the historical background of China and the status of women in the period of the 1940s to the 1970s. Secondly, I set out a framework for the thesis, matched and categorised the collected literature with the framework, and wrote the thesis; finally, I revised the final version and submitted the course thesis. My research found that the female drama of the White Hairy Daughter opera and ballet fully embodies the unequal gender treatment and social status of women in 1940s China. This work of White Hair Woman also portrays a more vivid image of Chinese women in the 1940s. However, the limitation of this thesis is that this thesis discusses the character lines and the related historical background from the score of White Hairy Woman, but it is difficult to find the literature that elaborates on the music of White Hairy Woman, and almost all of them focus on the content of White Hairy Woman's textual plot. The reason why the authors have some difficulty in discussing the musical score examples and the women's period characteristics is because there is very little literature that can help the authors to provide good ideas for their analyses. The final conclusion is that the female zeitgeist after the 1940s has given the female role of the White-haired Woman a deeper historical significance, and has provided scholars studying the White-haired Woman's operas and ballets with a new interpretation of female perspectives. It is also enough to show that White Hairy Woman is not only a successful musical theatre in 20th century China, but also a female theatre work that can promote Chinese women to gradually weaken sexism.

Intuitive credit attribution and the priority rule

ABSTRACT When a good idea is discovered, who gets credit for it? This is an important question in science, the arts, law, and everyday life. We suggest that people have intuitions about credit ownership that depend on three factors: (i) whether the idea suggests the discoverer is competent; (ii) whether the discovery elicits gratitude toward the discoverer; (iii) who the first individual to come up with the idea is. We test these intuitions in three vignette experiments with UK participants, in the context of priority disputes in science. In Experiment 1, participants find a discoverer less competent and award less credit to them for a scientific idea if they perceive that the discoverer could have plagiarized another discoverer, but attributions of credit are also shown to differ from attributions of competence. In Experiment 2, participants are more grateful toward, and award more credit to a discoverer who makes their discovery public. In Experiment 3, participants are more biased toward the first discoverer in terms of credit attribution than in terms of competence attribution or feelings of gratitude. In conclusion, we suggest that intuitions of credit ownership help explain the popularity and endurance of the priority rule in science, by which all the credit of a discovery is supposed to go to the first discoverer.

Is water delivery a good idea to prevent obstetric anal sphincter injuries in low risk primiparae? An exploratory study in a Swiss public teaching hospital

ObjectiveObstetric anal sphincter injuries are feared perineal injuries that are associated with increased pelvic floor disorders. The knowledge of influencing factors as the mode of delivery is therefore important.The aim of this study is to compare the rate of obstetric anal sphincter injuries in primiparae after water and bed deliveries. Study designIn this retrospective cohort study 3907 primiparae gave birth in water or on a bed in a Swiss teaching hospital.The diagnosis of obstetric anal sphincter injuries was confirmed by a consultant of obstetrics and gynecology and treated by them. The rates of these injuries after water and bed births were compared. Subgroup analysis was performed to detect possible associative factors, such as birth weight, episiotomy, use of oxytocin in first and second stage of labor. Results1844 (47.2 %) of the primiparae had a water delivery and 2063 (52.8 %) a bed delivery. 193 (4.94 %) were diagnosed with obstetric anal sphincter injuries, of which 68 (3.7 %) had a water delivery and 125 (6.1 %) a bed delivery, p < 0.001.Subgroup analysis revealed that, in the first and second stage of labor, the rate of obstetric anal sphincter injuries with oxytocin was significantly lower in water than in bed deliveries; p = 0.025, p < 0.017, respectively. The rate of obstetric anal sphincter injuries in the birth weight or episiotomy subgroups did not reach significance. ConclusionsIn a teaching hospital setting with standardized labor management, primiparae with a water delivery have the lowest risk for obstetric anal sphincter injuries.

Two-faced Janus of early French romanticism: Pierre Simon Ballanche as an esthetician and writer

The subject of the study is the fundamental philosophical and aesthetic problems in the aesthetics of Pierre Simon Ballanche, who stood at the origins of French romanticism. Two layers of his creativity - explicit and implicit - have been identified and analyzed. It is shown that his ideas about the art of romanticism are verbalized in a strict academic style. The implicit layer, is associated with Ballanche’s artistic prose. It includes philosophical and aesthetic poems, testifying the originality of his aesthetic position. Unlike most French romantics, who distance themselves from ancient culture as pagan in favor of Christianity and medieval art, Ballanche, in his talented paraphrases of mythological stories, romanticizes Antiquity, finding in it the beginnings of future Christian ideas of sublime love, mercy, sacrifice, beauty and goodness. The main conclusion of the study is the conclusion that art, according to Ballanche, plays a leading civilizational role in the cosmogonic-historical process. The core of Ballanche's implicit philosophical aesthetics is revealed - the original concept of palingenesis, interpreted by the author as a radical degeneration of the world for the sake of its future revival; it is precisely this stage of cultural and historical development that, in his opinion, marks romanticism. The author's special contribution lies in introducing into domestic scientific circulation, translated into Russian for the first time and analyzed the philosophical and aesthetic poems “Antigone”, “The Man with No Name”, “The Experience of Social Palingenesis. Orpheus".

Copper-containing POM-based hybrid P2Mo22V4Cu4 nanocluster as heterogeneous catalyst for the light-driven hydroxylation of benzene to phenol.

The current traditional phenol production process has many shortcomings, and the efficient and clean photocatalytic one-step oxidation to phenol is gradually attracting attention. Heteropolyacids (PMo10V2) with high-density Lewis acid active sites and excellent photoelectron transfer ability are ideal choices for catalytic reactions. In this study, a copper-modified isolated dimeric hybrid nanocluster, [Cu(pyim)2]2[Cu(pyim)2(P2MoVI20MoV2VIV4O82)]2·(H2O) (pyim = [2-(pyridin-2-yl)imidazole]), was synthesized by a convenient hydrothermal method. The structural analysis demonstrated that the compound was composed of metal-organic complexes containing pyim ligands, Keggin-type heteropolyacids, and transition metal copper ions. Remarkably, this not only solves the difficulty that the heteropolymeric acid cannot be recovered by dissolving in the solvent but also introduces the copper atom as a second active center. The catalyst exhibited a benzene conversion of 15.6% and a selectivity of 85.2% in a mixed solution of acetonitrile and acetic acid under optimal reaction conditions. After four catalytic cycles, the PXRD pattern proved that the catalyst was still stable. This study provides a good idea for photocatalytic reactions and other environmental applications.
