The Binary Black Hole Merger Rate Deviates from the Cosmic Star Formation Rate: A Tug of War between Metallicity and Delay Times

Gravitational-wave detectors are now making it possible to investigate how the merger rate of binary black holes (BBHs) evolves with redshift. In this study, we examine whether the BBH merger rate of isolated binaries deviates from a scaled star formation rate density (SFRD)—a frequently used model in state-of-the-art research. To address this question, we conduct population synthesis simulations using COMPAS with a grid of stellar evolution models, calculate their cosmological merger rates, and compare them to a scaled SFRD. We find that our simulated rates deviate by factors up to 3.5 at z ∼ 0 and 5 at z ∼ 9 due to two main phenomena: (i) the formation efficiency of BBHs is an order of magnitude higher at low metallicities than at solar metallicity, and (ii) BBHs experience a wide range of delays (from a few megayears to many gigayears) between formation and merger. The deviations are similar when comparing to a delayed SFRD, and even larger (up to ∼10×) when comparing to SFRD-based models scaled to the local merger rate. Interestingly, our simulations find that the BBH delay time distribution is redshift dependent, increasing the complexity of the redshift distribution of mergers. We find similar results for simulated merger rates of black hole–neutron stars (BHNSs) and binary neutron stars (BNSs). We conclude that the rate of BBH, BHNS, and BNS mergers from the isolated channel can significantly deviate from a scaled SFRD, and that future measurements of the merger rate will provide insights into the formation pathways of gravitational-wave sources.

Asymmetric arms races between predators and prey: a tug of war between the life-dinner principle and the rare-enemy principle.

Antagonistic co-evolution can be asymmetric, where one species lags behind another. Asymmetry in a predator-prey context is expressed by the 'life-dinner principle', a classic informal model predicting that prey should be in some sense ahead in this arms race, since prey are running for their lives, while predators lag as they only run for their dinner. The model has undergone surprisingly little theoretical scrutiny. We derive analytical models that show coevolutionary outcomes do not always align with the life-dinner principle. Our results show that other important asymmetries can easily reverse the outcome, especially the rare-enemy principle: predators are usually outnumbered by their prey, sometimes substantially (trophic asymmetry), which can make selection on prey relatively weak. We additionally show that the antagonists typically exhibit different evolutionary responses to a situation where both predator and prey start out as equally fast runners. Although predators sometimes become so efficient that attacks always succeed, attack success often reaches a stable intermediate value. We conclude that the life-dinner principle has some validity as a metaphor, but its effect is of an 'all else being equal' type, which is surprisingly easily overridden by other features of the evolutionary dynamics.

Carpal Tunnel Syndrome in Elite Female Tug-of-War Athletes: Prevalence and Risk Factor Analysis.

Background: Tug-of-War (TOW) games involve repetitive hand movements and vigorous force, raising the risk of peripheral neuropathy in the upper extremities. The prevalence of carpal tunnel syndrome (CTS) in TOW athletes remains unclear. We hypothesize that elite female TOW athletes have a higher prevalence of CTS than the general population. Methods: Twenty-nine female TOW athletes were recruited from a national team and participated in the study. CTS was clinically diagnosed by history taking and physical examination. Nerve conduction studies (NCS) were additionally performed to confirm CTS. Results: Twelve athletes were clinically diagnosed with CTS; however, only nine were confirmed by NCS. Ten athletes were diagnosed with subclinical CTS by NCS, while seven were classified as truly-non-CTS by both clinical assessment and NCS. The prevalence of CTS and subclinical CTS among the athletes was found to be 33.3% and 37.0%, respectively, significantly higher than 2.7% in the general population by electrodiagnosis. The body weight (p = 0.025) of the athletes with CTS and subclinical CTS was significantly different from those of the athletes without CTS. Conclusions: Our observations revealed a higher prevalence of CTS among elite female TOW athletes, with body weight being a risk factor. The forceful grasping and pulling of the rope may contribute to the development of CTS.

Indonesiaʼs energy transition: Dependency, subsidies and renewables

AbstractIndonesiaʼs economy is highly dependent on the fossil fuel industry as evidenced in measures of non‐taxable revenue, energy subsidy, energy mix and regulatory flexibility. To cut carbon emissions by 41% in 2030, the energy system needs to transition faster than anticipated through progressive reforms and investment. Policy makers understandably are fearful of the shocks and unrests resulted from fossil fuel subsidy reform. However, the fears were shown to be an over‐reaction, especially if poorer households were supported. The state‐owned enterprise, Perusahaan Listrik Negara, is the central player in the tug of war between the fossil fuel and renewable sectors. The government should signal unwavering support for international investment in the renewables, and update the regulation on rooftop solar that boosts return on investment for domestic households. International investors will need modelling of cost competitiveness of wind farms against coal‐fired plants in more remote areas.

Molecular-Level Dysregulation of Insulin Pathways and Inflammatory Processes in Peripheral Blood Mononuclear Cells by Circadian Misalignment.

Circadian misalignment due to night work has been associated with an elevated risk for chronic diseases. We investigated the effects of circadian misalignment using shotgun protein profiling of peripheral blood mononuclear cells taken from healthy humans during a constant routine protocol, which was conducted immediately after participants had been subjected to a 3-day simulated night shift schedule or a 3-day simulated day shift schedule. By comparing proteomic profiles between the simulated shift conditions, we identified proteins and pathways that are associated with the effects of circadian misalignment and observed that insulin regulation pathways and inflammation-related proteins displayed markedly different temporal patterns after simulated night shift. Further, by integrating the proteomic profiles with previously assessed metabolomic profiles in a network-based approach, we found key associations between circadian dysregulation of protein-level pathways and metabolites of interest in the context of chronic metabolic diseases. Endogenous circadian rhythms in circulating glucose and insulin differed between the simulated shift conditions. Overall, our results suggest that circadian misalignment is associated with a tug of war between central clock mechanisms controlling insulin secretion and peripheral clock mechanisms regulating insulin sensitivity, which may lead to adverse long-term outcomes such as diabetes and obesity. Our study provides a molecular-level mechanism linking circadian misalignment and adverse long-term health consequences of night work.

Advocating green economy in India: The tug of war among income inequality, export diversification, and environmental quality

AbstractGlobally, most countries have shown strong commitments toward the attainment of sustainable development goals before 2023. Thus, this study focuses on analyzing such commitments toward the attainment of SDGs (7, 8, 10, and 13), respectively. The study evaluates the role played by income inequalities, export diversification, and economic growth in restoring a sustainable environment in India from 1970 to 2019. To achieve its objective, the study employed the novel Fourier autoregressive distributed lag (ARDL) method. Remarkably, the study utilizes the load capacity factor (LCF) as a unique indicator for environmental sustainability. The LCF, which takes into account both biocapacity and ecological footprint, is one of the most complete indicators of environmental quality to date. The study's findings revealed a long‐run relationship between the LCF and all the explanatory variables. According to the Fourier ARDL results, income inequality and renewable energy improve environmental quality. At the same time, economic growth and export diversification negatively impact the LCF in India both within the short and long‐run periods. Conclusion and policy prescriptions are included in the study.

Diferencias cinemáticas en el Tug of War indoor y outdoor: Estudio de caso

The tug of war (TOW) is a sport with a high physical and technical demand. Very few investigations have been carried out on the biomechanics of TOW and all of them in the indoor modality. The main objective of this study is to describe and differentiate the kinematics of indoor and outdoor TOW. An experienced puller was recorded in two world championships of the two modalities in consecutive years. Although the position of the hands on the rope, the arms and the inclination of the body are similar, important differences were registered both in the lower body and in the position of the body, with both shoulders and hips forward in the case of the indoor modality and with the hip and left shoulder forward in the outdoor modality. This research evidences the different techniques used in the two modalities of TOW and their possible relationship both with the risk of injury to some parts of the body, and with the greater demands of these parts.

Genetic study on heritability and novel SNP loci of temperament in Chinese Kunming Dog

Chinese Kunming dog (CKD) is a working breed widely used by army, customs and police across the country. To better evaluate a breeding population's potential working performance and implement selective breeding for future offspring, a temperament test with five subsets, including following to trainer (FO), reaction to stranger (RS), tease by towel (TT), chase and fetch (CF) and tug of war (TW), was annually operated by the Kunming Police Dog Base since 2019. To fully utilize this behavioral data, 92 breeding animals of CKDs were genotyped by a 50K SNP chip, and a GWAS method supporting repeated measurement was adopted to estimate heritabilities and explore genetic variants associated with the five subsets. The heritabilities estimated for the five subsets ranged from 0,03 to 0.14, which showed a possibility for genetic improvement. Meanwhile, in total seven novel SNPs were identified associated with subsets FO, TT, CF and TW. In addition to that five of the seven loci are separately located within ACOT11, PRDM16, SAMD12, CPA1 and ENSCAFG00000023173 genes. Nevertheless, genetic effects of these novel loci on dog temperament should be further validated by a larger dataset in the future.

Omnibus Law on Job Creation: Tug of War over Environmental Protection Authority Amid the Climate Crisis

This article analyses the relationship between national and local governments regarding environmental protection amid the climate crisis after the Omnibus Law on Job Creation issuance. It is a normative study of legal concepts in the statutory system. The results point out that Omnibus Law on Job Creation has changed the paradigm of environmental protection from “permission” to “consent” or “agreement.” The policy weakened the local government’s role in protecting the environment amidst the climate crisis. Apart from that, the Omnibus Law has also created a pattern of centralization by reducing the authority of local governments—which is only interpreted as a deconcentrated primate in implementing the law provisions.

P53 and RNA viruses: The tug of war.

Host factors play essential roles in viral infection, and their interactions with viral proteins are necessary for establishing effective pathogenesis. p53 is a host factor that maintains genomic integrity by controlling cell-cycle progression and cell survival. It is a well-known tumor suppressor protein that gets activated by various stress signals, thereby regulating cellular pathways. The cellular outcomes from different stresses are tightly related to p53 dynamics, including its alterations at gene, mRNA, or protein levels. p53 also contributes to immune responses leading to the abolition of viral pathogens. In turn, the viruses have evolved strategies to subvert p53-mediated host responses to improve their life cycle and pathogenesis. Some viruses attenuate wild-type p53 (WT-p53) function for successful pathogenesis, including degradation and sequestration of p53. In contrast, some others exploit the WT-p53 function through regulation at the transcriptional/translational level to spread infection. One area in which the importance of such host factors is increasingly emerging is the positive-strand RNA viruses that cause fatal viral infections. In this review, we provide insight into all the possible mechanisms of p53 modulation exploited by the positive-strand RNA viruses to establish infection. This article is categorized under: RNA Interactions with Proteins and Other Molecules > Protein-RNA Interactions: Functional Implications Translation > Regulation RNA in Disease and Development > RNA in Disease.

Karya Tari Manyeso Terinspirasi Dari Ritual Mandaghai Di Desa Lumindai Kecamatan Barangin Kota Sawahlunto

The Maarak tambun process aims to gather from the family and niniak mamak to find an agreement in the implementation of the batagak house. Maarak Tambun has two kinds of rituals, namely, Mandaghai (bloody), and mamujo (worshipping). The methods that were born in the concept of this manyeso dance work include observation, data processing, literature study, selection of dance supporters, exploration, movement arrangement, improvisation, and evaluation. The form in the manyeso dance has three parts, the first part describes the pain experienced by all family members and does not go away, the second part is a problem experienced by a person so that he becomes limping when carrying it. In this section, the property of the fabric is described as a problem that binds the dancer's body parts. The conflict in this work is the struggle for cloth with the intention that the problems that occur are like a tug of war that is being felt by someone. The third part of the problem can be solved if we draw closer to Allah.

Phosphatidylethanolamine and Cholesterol Promote Hemifusion Formation: A Tug of War between Membrane Interfacial Order and Intrinsic Negative Curvature of Lipids.

Membrane fusion is an important process for the survival of eukaryotes. The shape of lipids plays an important role in fusion by stabilizing nonlamellar fusion intermediates. Lipids with intrinsic positive curvature such as lysophosphatidylcholine and others inhibit hemifusion formation, whereas lipids having intrinsic negative curvature, e.g., phosphatidylethanolamine and cholesterol (CH), are known to promote hemifusion formation. In this work, we have measured the effect of dioleoylphosphatidylethanolamine (DOPE) and CH on the depth-dependent organization, dynamics, and fusion of dioleoylphosphatidylcholine membranes. Both DOPE and CH promote hemifusion formation despite their ability to order the interfacial and acyl chain region of the membrane and block water percolation at these regions. Generally, membrane ordering and inhibition of water percolation at the acyl chain region are detrimental to membrane fusion. This clearly emphasizes the importance of intrinsic negative curvature of lipids in membrane fusion. Interestingly, DOPE and CH show differential effects on the rate of hemifusion formation, which might be owing to their ability to induce order at the interfacial region and intrinsic negative curvature. Overall, our result is significant in understanding the role of lipidic shape in membrane fusion.

Energy Surplus and an Atmosphere‐Land‐Surface “Tug of War” Control Future Evapotranspiration

AbstractThe 21st century evapotranspiration (ET) trends over the continental U.S. are assessed using innovative, energy‐based principles. Annual ET is projected to increase with high confidence at the rate of 20 mm for every 1℃ of rise in near‐surface air temperature, or 0.45 or 0.98 mm/year/year, depending on the emission scenario. The ET trajectory is dominated (58%) by the increase of land‐surface net radiative energy. An enhancement of the fraction of energy taken up by ET becomes a more important controller (53%) in late 21st century, under the high emission scenario. This increase is explained by the “tug of war” between atmospheric vapor demand and land‐surface ability to supply water. An assessment of future water availability (precipitation minus ET) shows no significant changes at the continental scale. This outcome nevertheless hides strong spatial variability, emphasizing the role of ET in shaping the distribution of water availability among human populations.

Regulation of Halal Product Certification in The Dynamics of Indonesian Legal Politics

The purpose of this study is to explore how the regulation of halal product certification in the dynamics of Indonesian legal politics, especially since the existence of Law No. 8 of 1999 concerning Consumer Protection to the presence of Law No. 33 of 2014 concerning Halal Product Guarantee. UUPK as the basis for LP POM MUI to carry out halal product certification as well as halal labeling using the MUI halal logo. The presence of the JPH Law has an impact on policy changes and a new governance paradigm which has implications for causing a tug of war between MUI, the government and the legislature. By using normative juridical research topilogy and qualitative data analysis, it can be concluded: First, the Certification regulation has dynamics, especially during the discussion of the JPH Bill, until there is an interesting dance between MUI, the Government including the DPR faction faction regarding the institution authorized to implement certification, including whether or not it is mandatory for business actors to carry out certification. Second, halal certification which was originally carried out by MUI through a detailed examination by LPPOM MUI, after the decision of the JPH Law, the authority to carry out certification is carried out by BPJPH under the auspices of the Ministry of Religion by still involving MUI but using a new halal label / logo.

Genome engineering of disease susceptibility genes for enhancing resistance in plants.

Introgression of disease resistance genes (R-genes) to fight against an array of phytopathogens takes several years using conventional breeding approaches. Pathogens develop mechanism(s) to escape plants immune system by evolving new strains/races, thus making them susceptible to disease. Conversely, disruption of host susceptibility factors (or S-genes) provides opportunities for resistance breeding in crops. S-genes are often exploited by phytopathogens to promote their growth and infection. Therefore, identification and targeting of disease susceptibility genes (S-genes) are gaining more attention for the acquisition of resistance in plants. Genome engineering of S-genes results in targeted, transgene-free gene modification through CRISPR-Cas-mediated technology and has been reported in several agriculturally important crops. In this review, we discuss the defense mechanism in plants against phytopathogens, tug of war between R-genes and S-genes, in silico techniques for identification of host-target (S-) genes and pathogen effector molecule(s), CRISPR-Cas-mediated S-gene engineering, its applications, challenges, and future prospects.

A tug of war between centralization and decentralization: the co-evolution of urban governance and water risks in Guwahati, India

Intermediate cities in Asia and Africa house more than 60% of the world’s urban population. More than 54% of the people here face high levels of water stress and are increasingly vulnerable to water-related risks such as floods, limited access to safe drinking water and water pollution. These urban water risks are complex outcomes of climate change, land use changes, governance failures, and social inequities. This study examines the co-evolution of three water risks and governance responses through the case of Guwahati, India. Guwahati, on the Brahmaputra River in the Northeast of India, serves as a case of an intermediate city to demonstrate changes in water risk governance trends. We focus on studying the connected governance responses to changes in three interrelated water risks, i.e., domestic water supply, urban floods, and river pollution. The shifts in the socio-political structures for these risks are assessed by combining historical institutionalism with multi-level perspective theory. The results show that despite the growing diversity of actors and devolution of responsibilities in cities to mitigate water risks, there is an ongoing tug-of-war between centralized and decentralized modes of decision-making. Contrary to the recommendations for decentralized urban governance, the trend is currently tugging towards a centralized decision-making mode. However, when differences arise between the local and national, local actors within their limited frames of action manage to circumnavigate nationally dictated mandates to fit local needs.
