Relationship Between use of Dating apps and Sociodemographic Variables, Sexual Attitudes, and Sexual risk Behaviors
Authors: Blanc Andrea 
Published: October 2023

Abstract
Introduction
Although some studies have found a link between dating apps and sociodemographic variables, sexual attitudes, and sexual risk behaviors, few studies in Spain have explored these relationships. This study analyzes the relationship between the use of dating apps and these variables in this country.

Method
A total of 2288 people aged between 18 and 35 years completed a questionnaire, which, in addition to sociodemographic variables, contained questions on the use of dating apps, a measure of attitudes toward online sexual behaviors, and indicators of sexual risk behaviors.

Results
The percentage of men using dating apps is higher than that of women, and the percentage of LGB users is higher than that of heterosexuals. In addition, users have more positive attitudes toward online sexual behavior than non-users. In general, users are also found to have more sexual partners than non-users, although they more frequently use condoms for vaginal intercourse and anal sex.

Conclusion
The present study provides evidence for the relationship between the use of dating apps and certain variables in Spain.

Policy Implications
Dating apps do not have to be equated with sexual risk, but condom use should continue to be encouraged, especially among those who have multiple sexual partners.

AbstractThe size and complexity of datasets resulting from comparative research experiments in the agricultural domain is constantly increasing. Often the number of variables measured in an experiment exceeds the number of experimental units composing the experiment. When there is a necessity to model the covariance relationships that exist between variables in these experiments, estimation difficulties can arise due to the resulting covariance structure being of reduced rank. A statistical method, based in a linear mixed model framework, is presented for the analysis of designed experiments where datasets are characterised by a greater number of variables than experimental units, and for which the modelling of complex covariance structures between variables is desired. Aided by a clustering algorithm, the method enables the estimation of covariance through the introduction of covariance clusters as random effects into the modelling framework, providing an extension of the traditional variance components model for building covariance structures. The method was applied to a multi-phase mass spectrometry-based proteomics experiment, with the aim of exploring changes in the proteome of barley grain over time during the malting process. The modelling approach provides a new linear mixed model-based method for the estimation of covariance structures between variables measured from designed experiments, when there are a small number of experimental units, or observations, informing covariance parameter estimates.

AbstractAlthough the recognition of Indigenous Peoples’ contributions to climate governance by the international community has gradually increased, a rights-based approach in national climate action is still largely absent. This article analyses the recognition of Indigenous Peoples’ rights in Nationally Determined Contributions (NDCs) under the Paris Agreement. We conducted a content analysis of all NDCs submitted between 2016 and May 2022. Through a five-pronged framework of sustainable self-determination, we assessed how the NDCs recognise: i. Indigenous Peoples as rights-holders; ii. Indigenous jurisdiction over land; iii. Indigenous knowledge systems; iv. Indigenous Peoples’ right to full and effective participation in climate governance; and v. the legacy of colonialism. NDCs with references related to Indigenous Peoples are increasing. However, questions remain regarding their sincerity and commitment to implementation. States must therefore make more significant efforts to ensure that the NDCs take a rights-based approach and contribute to strengthening Indigenous Peoples’ role and say in climate governance.
Thermodynamic analysis on a magnetic refrigeration system
Authors: Lee Jong Suk 
Published: October 2023

AbstractMagnetic refrigeration utilizes the magnetocaloric effect of a magnetic material, whose temperature changes according to the change of magnetic field strength. It is regarded as an eco-friendly refrigeration technology in that it uses magnetic materials as refrigerants instead of CFC, HCFC, and HFC refrigerants used in vapor compression refrigeration. It is also regarded as an energy-efficient refrigeration technology in that it does not use noisy and power-consuming compressors. This paper presents thermodynamic analysis on a magnetic refrigeration system using experimental results obtained from a magnetic refrigeration apparatus. The magnetic refrigeration apparatus was built using two sets of concentric Halbach cylinders consisting of permanent magnet segments. Specifically the coefficient of performance (COP) of the magnetic refrigeration system was calculated using the energy removed from the working fluid across an AMR bed and the work input to run electric motors.
Changes in El Niño characteristics and air–sea feedback mechanisms under progressive global warming
Authors: Shen Min-Hua , Yu Jia-Yuh 
Published: October 2023

AbstractIn this study, we investigate the potential changes of El Niño characteristics, including intensity, frequency and CP/EP El Niño ratio, under progressive global warming based on the 140-year CMIP6 model simulation outputs with the 1pctCO2 experiment. Major air-sea feedback mechanisms attributing to the changes are also examined. The CMIP6 ensemble means project a slight enhancement of El Niño intensity by about 2% and a modest increase of El Niño frequency by about 4% from the first to the second 70-year periods. It is found that these small changes result from the opposite response to global warming between CP and EP El Niño, i.e., the intensity of EP El Niño is projected to weaken by nearly 4.6% while the intensity of CP El Niño is projected to increase by about 4.5%. Since CP El Niño occurs more frequently than EP El Niño in CMIP6 simulations, this leads to a slight enhancement of the total El Niño intensity if these two types of El Niño were not separated. A similar situation occurs in projecting the future change of El Niño frequency, i.e., the frequency of EP El Niño is projected to decrease by about 1.4% while the frequency of CP El Niño is projected to increase by about 2%, thereby leading to a modest increase of the total El Niño frequency. By comparing the variance explained by key air-sea feedback mechanism between the two 70-year periods, we also note that the increased CP/EP ratio can be explained by the enhanced role played by the SF (seasonal footprinting) mechanism in a warmer atmosphere. Our study also points out that, as long as a climate model can correctly produce the intensity (variance) of major air-sea feedback mechanisms, the relationship between changes in El Niño characteristics and changes in feedback mechanisms can be physically robust.

Abstract

Introduction
Surgical abdominal emergencies in children are responsible for high morbidity and mortality. They are numerous and their management in Africa is difficult. The management of non-traumatic abdominal emergencies in children in a regional hospital in Togo is described.

Method
and study setting: This was a single-center, retrospective and descriptive study conducted over a 12-month period. It included all children aged 0–15 years treated at the hospital for non-traumatic abdominal surgical emergencies.

Results
We reported 217 cases of non-traumatic abdominal surgical emergencies in children. We noted a male predominance with a sex ratio of 1.57. Similarly, grandchildren were predominant (44.70 %). A low school attendance rate was noted (21.20 %) and the children were mostly from poor families (32.72 %). The average consultation time was 5.3 ± 1.03 days. Pain was the main symptom and was present in all children. An unprepared abdominal X-ray was the main imaging procedure performed (77.18 %). These conditions were dominated by peritonitis (56.68 %). These were mainly ileal perforations. All the children received surgical treatment. The postoperative course was marked by complications in 104 children (47,93 %) and 14 deaths (6,45 %).

Conclusion
Non-traumatic abdominal surgical emergencies in children are dominated by peritonitis in rural Togo. They could be related to poverty. An effective policy of universal access to health care is essential.

Statistical determinism in non-Lipschitz dynamical systems
Authors: DRIVAS THEODORE D. , MAILYBAEV ALEXEI A. , RAIBEKAS ARTEM 
Published: October 2023

AbstractWe study a class of ordinary differential equations with a non-Lipschitz point singularity that admits non-unique solutions through this point. As a selection criterion, we introduce stochastic regularizations depending on a parameter
$\nu $
: the regularized dynamics is globally defined for each
$\nu> 0$
, and the original singular system is recovered in the limit of vanishing
$\nu $
. We prove that this limit yields a unique statistical solution independent of regularization when the deterministic system possesses a chaotic attractor having a physical measure with the convergence to equilibrium property. In this case, solutions become spontaneously stochastic after passing through the singularity: they are selected randomly with an intrinsic probability distribution.
CHANGES IN FOSSIL CO2 EMISSIONS IN MEXICO CITY DURING THE COVID-19 LOCKDOWN DEDUCED FROM ATMOSPHERIC RADIOCARBON CONCENTRATIONS

Published: October 2023

ABSTRACTWe present atmospheric radiocarbon concentrations in CO2 integrated samples taken between January 2019 and December 2021 in the Mexico City Metropolitan Area (MCMA) and explain the variations in terms of changes in emission sources associated with the COVID-19 lockdown restrictions imposed from March 2020. Δ14C values for samples collected during 2019 range between –44.15‰ and –13.17‰, with lower values during months with higher fossil fuels consumption and air stagnation, whereas higher values were found for periods with high number of fires around MCMA or wet months with higher contribution of heterotrophic respiration. For samples collected during 2020, Δ14C values range between –17.7‰ and 2.25‰, with an increasing trend immediately after the initial lockdown and higher values obtained for samples collected during lockdown phases 2 and 3 and the period of extremely high epidemic risk. This agrees with the 38% and 52% decrease in gasoline and diesel sales. Once essential activities gradually opened from July 2020, Δ14C follow a decreasing trend as vehicle traffic started to increase again. Δ14C values for samples collected during 2021 range from –32.89‰ to –10.27‰, with the higher value obtained during a period of extremely high epidemic risk with a 30% reduction in gasoline and diesel consumption. Despite the complexity of emission sources in MCMA, from Δ14C variations it was possible to identify changes in fossil CO2 emissions resulting from the significant reduction in vehicle traffic due to the COVID-19 lockdown and the restrictions imposed to control transmission of the disease.
Conscripting communalism: surveillance and resistance in contemporary Mauritius
Authors: Auerbach Jess 
Published: October 2023

AbstractIn this article I explore changing state–citizen relationships in Mauritius. To do so, I outline and provide analysis of the system through which this Indian Ocean island has historically managed its diversity – a process that I call conscripting communalism. Conscripting communalism was formulated at independence in a context of behavioural predictions for the future that the internet era has challenged in powerful ways. To illustrate my argument, I explore three specific moments when ethnic and religious discourses were surpassed by collective concern within a rapidly authoritarianizing state: first, the sinking of the Wakashio oil tanker off the coast of Mauritius in 2020, which resulted in national solidarity towards the environment rather than communal violence; second, proposed legislation put forward by the Mauritian Information and Communication Technology Authority (ICTA) in 2021, which attempted to enable state surveillance of social media and which was soundly resisted by both domestic and external parties. And finally, I explore 2022 accusations that the Mauritian government authorized the installation of digital interception technology by representatives of the Indian state on one of the country’s fibre optic cables. The article argues that Mauritius represents an important site of analysis of the tensions between competing global visions of human rights, political autonomy, surveillance, solidarity and expectations for the future and the role of the internet in shaping these competing visions. I explore how new technologies have become the tools of both repression and resistance. The implications ripple far beyond the island.

AbstractOfficial protection of an exploited species sometimes precedes any quantitative understanding of its use, including any dependence of local residents on it for food and livelihood. Conservation initiatives could suffer without this information. The Goliath frog Conraua goliath is iconic globally because of its large size, and is categorized as Endangered on the IUCN Red List. The main threat to this species in Cameroon is overexploitation, but any associated socio-economic aspects of this have not been quantified. We provide insights into local perceptions of the Goliath frog and its consumption through structured interviews with 223 people living alongside this species. The Goliath frog is well known and hunted both for home consumption and the wild meat trade. We trailed seven collaborative Cameroonian Goliath frog hunters over two seasons to determine offtake. A total of 192 Goliath frogs were collected by these hunters, peaking in March. The hunters used nets, shotguns and spears. Their catch was eaten at home or sold fresh within the community or to travellers for XAF 1,500–5,000 (USD 3–10) each. We also studied the Goliath frog trade by examining the databases of the Cameroonian Ministry of Forestry and Wildlife, and CITES. CITES and hunters reported large exports of Goliath frogs but no trade was documented by the Ministry of Forestry and Wildlife. To support conservation planning, this study provides preliminary quantitative information on the extent of the threat of hunting to this Endangered frog.

AbstractThis paper presents an integrated power amplifier (PA) following the orthogonal load-modulated balanced amplifier (OLMBA) topology. The fixed-phase prototype in this paper is implemented with 22 nm complementary metal oxide semiconductor (CMOS) fully depleted silicon-on-insulator (FDSOI) process. The proposed PA operates at 26 GHz frequency range, where it achieves 19.5 dBm output power, 16.6 dB gain, 15.7% power added efficiency, and 18.3 dBm output 1-dB compression point ($P_{\rm 1\,dB}$). The PA is also tested with high dynamic range modulated signals, and it achieves, respectively, 11.4 dBm and 4.9 dBm average output power (Pavg) with 100 MHz and 400 MHz 64-QAM third-generation partnership project/new radio frequency range 2 signals, and 14 dBm Pavg with 0.6 Gb/s (120 MHz) single carrier 64-QAM signal, measured at 26 GHz and using −28 dBc adjacent channel leakage ratio and −21.9 dB (8%) error vector magnitude as threshold values. The proposed OLMBA is also compared to a stand-alone quadrature-balanced PA. Modulated measurements show that the stand-alone quadrature-balanced PA has better linearity in deep back-off, but the OLMBA has better efficiency.
Elite non-cooperation in polarized democracies: Constitution-making deferral, the entry referendum and the seeds of the Chilean failure
Authors: García-Huidobro Luis Eugenio 
Published: October 2023

AbstractThis article extends the study of the shortcomings of the constitution-making design that contributed to the failure of the Chilean process by addressing a largely overlooked aspect: the 2020 entry referendum. By placing two competing constitution-making models on the ballot, the political elites delegated to the voters a highly conflictual aspect of the process design that prevented cooperation among them. While some political parties approached the disagreements placed on the ballot as an opportunity to reopen discussions already settled by the 2019 Agreement, others interpreted the move as a cancellation of the political insurance contained in the Agreement. This exacerbated the existing polarization among political elites and imperiled prospects for the success of the process.
Farewell to constituent power? The Conference on the Future of Europe, citizens’ assemblies and the democratic minimum
Authors: Patberg Markus 
Published: October 2023

AbstractIn this article, I ask about the extent to which the Conference on the Future of Europe (CoFoE) has advanced democracy in the European Union. I critically engage with the claim that the CoFoE’s success should not be measured by whether it enabled constituent power, or ultimately results in treaty reforms, but by the fact that, by introducing citizens’ assemblies to EU politics, it has laid the foundation for participatory democracy in the European Union. Drawing on established theories of participatory democracy, I argue that this interpretation misses the point. To put forward an alternative view, I revisit James Bohman’s concept of a democratic minimum. The best democratic defence of permanent EU citizens’ assemblies is that they could provide citizens with the capacity to initiate deliberation about common concerns – and thus function as a nucleus for constituent power in the European Union. Nevertheless, the idea should be viewed with caution, as permanent citizens’ assemblies could just as well become a democratic fig-leaf allowing EU institutions to reject calls for fundamental reforms. Much therefore depends on their institutional design.
Expansion of Ocean Anoxia During Glacial Periods Recorded in the Cobalt Flux to Pelagic Sediments
Authors: Hawco Nicholas J. , Foreman Rhea K. 
Published: October 2023

AbstractThe expansion of oxygen deficient zones (ODZs) within the ocean's interior is anticipated to be a major consequence of anthropogenic climate change, but past changes in ODZs are poorly defined. Recent mapping efforts have revealed plumes of the redox‐active metal cobalt within ODZs, driving a basin‐scale correlation between high cobalt and low O2. Here, we investigate the cobalt flux to Equatorial Pacific sediments along the Line Islands Ridge as a novel record of basin‐scale fluctuations in ODZ extent. After accounting for remobilization by diagenesis, we document a ∼40% increase in cobalt accumulation over the last glacial period, with a more pronounced peak during the Last Glacial Maximum, indicative of larger ODZs compared to the Holocene. Our results link ODZ expansion with colder climates and lend support to model‐based assertions that ongoing deoxygenation may reflect a transient response to warming.
The IL-17 family in diseases: from bench to bedside

Published: October 2023

AbstractThe interleukin-17 (IL-17) family comprises six members (IL-17A–17F), and recently, all of its related receptors have been discovered. IL-17 was first discovered approximately 30 years ago. Members of this family have various biological functions, including driving an inflammatory cascade during infections and autoimmune diseases, as well as boosting protective immunity against various pathogens. IL-17 is a highly versatile proinflammatory cytokine necessary for vital processes including host immune defenses, tissue repair, inflammatory disease pathogenesis, and cancer progression. However, how IL-17 performs these functions remains controversial. The multifunctional properties of IL-17 have attracted research interest, and emerging data have gradually improved our understanding of the IL-17 signaling pathway. However, a comprehensive review is required to understand its role in both host defense functions and pathogenesis in the body. This review can aid researchers in better understanding the mechanisms underlying IL-17’s roles in vivo and provide a theoretical basis for future studies aiming to regulate IL-17 expression and function. This review discusses recent progress in understanding the IL-17 signaling pathway and its physiological roles. In addition, we present the mechanism underlying IL-17’s role in various pathologies, particularly, in IL-17-induced systemic lupus erythematosus and IL-17-related tumor cell transformation and metastasis. In addition, we have briefly discussed promising developments in the diagnosis and treatment of autoimmune diseases and tumors.

AbstractDespite its involvement in various cancers, the function of the deubiquitinase USP1 (ubiquitin-specific protease 1) is unexplored in cholangiocarcinoma (CCA). In this study, we provide evidence that USP1 promotes CCA progression through the stabilization of Poly (ADP-ribose) polymerase 1 (PARP1), consistent with the observation that both USP1 and PARP1 are upregulated in human CCA. Proteomics and ubiquitylome analysis of USP1-overexpressing CCA cells nominated PARP1 as a top USP1 substrate. Indeed, their direct interaction was validated by a series of immunofluorescence, co-immunoprecipitation (CO-IP), and GST pull-down assays, and their interaction regions were identified using deletion mutants. Mechanistically, USP1 removes the ubiquitin chain at K197 of PARP1 to prevent its proteasomal degradation, with the consequent PARP1 stabilization being necessary and sufficient to promote the growth and metastasis of CCA in vitro and in vivo. Additionally, we identified the acetyltransferase GCN5 as acetylating USP1 at K130, enhancing the affinity between USP1 and PARP1 and further increasing PARP1 protein stabilization. Finally, both USP1 and PARP1 are significantly associated with poor survival in CCA patients. These findings describe PARP1 as a novel deubiquitination target of USP1 and a potential therapeutic target for CCA.
