A survey on popularity bias in recommender systems

Published: July 2024

AbstractRecommender systems help people find relevant content in a personalized way. One main promise of such systems is that they are able to increase the visibility of items in the long tail, i.e., the lesser-known items in a catalogue. Existing research, however, suggests that in many situations today’s recommendation algorithms instead exhibit a popularity bias, meaning that they often focus on rather popular items in their recommendations. Such a bias may not only lead to the limited value of the recommendations for consumers and providers in the short run, but it may also cause undesired reinforcement effects over time. In this paper, we discuss the potential reasons for popularity bias and review existing approaches to detect, quantify and mitigate popularity bias in recommender systems. Our survey, therefore, includes both an overview of the computational metrics used in the literature as well as a review of the main technical approaches to reduce the bias. Furthermore, we critically discuss today’s literature, where we observe that the research is almost entirely based on computational experiments and on certain assumptions regarding the practical effects of including long-tail items in the recommendations.

AbstractThe aim of the present study is to develop a pH-sensing biopolymer film based on the immobilization of red cabbage extract (RCE) within bacterial cellulose (BC) to detect contamination and gamma radiation exposure in cucumbers. The results obtained show a sensitivity to pH changes for RCE in its aqueous form and that incorporated within BC films (RCE-BC), both showed color change correlated to bacterial growth (R2 = 0.91), this was supported with increase in pH values from 2 to 12 (R2 = 0.98). RCE and RCE-BC exposure to gamma radiation (0, 2.5, 5, 10, 15, 20, 25 kGy) resulted in gradual decrease in color that was more evident in RCE aqueous samples. To sense bacterial contamination of cucumbers, the total count was followed at 0, 5, 10 and 15 days in cold storage conditions and was found to reach 9.13 and 5.47 log cfu/mL for non-irradiated and 2 kGy irradiated samples, respectively. The main isolates detected throughout this storage period were identified as Pseudomonas fluorescens, Erwinia sp. Pantoea agglomerans using matrix assisted laser desorption ionization–time of flight-ms (MALDI–TOF–MS). Bacterial growth in stored irradiated cucumbers was detected by color change within 5 and 10 days of storage, after which there was no evident change. This is very useful since contamination within the early days of storage cannot be sensed with the naked eye. This study is the first to highlight utilizing RCE and RCE-BC as eco-friendly pH-sensing indicator films for intelligent food packaging to detect both food contamination and gamma preservation for refrigerator stored cucumbers.

Published: July 2024

AbstractClassification of gene trees is an important task both in the analysis of multi-locus phylogenetic data, and assessment of the convergence of Markov Chain Monte Carlo (MCMC) analyses used in Bayesian phylogenetic tree reconstruction. The logistic regression model is one of the most popular classification models in statistical learning, thanks to its computational speed and interpretability. However, it is not appropriate to directly apply the standard logistic regression model to a set of phylogenetic trees, as the space of phylogenetic trees is non-Euclidean and thus contradicts the standard assumptions on covariates. It is well-known in tropical geometry and phylogenetics that the space of phylogenetic trees is a tropical linear space in terms of the max-plus algebra. Therefore, in this paper, we propose an analogue approach of the logistic regression model in the setting of tropical geometry. Our proposed method outperforms classical logistic regression in terms of Area under the ROC Curve in numerical examples, including with data generated by the multi-species coalescent model. Theoretical properties such as statistical consistency have been proved and generalization error rates have been derived. Finally, our classification algorithm is proposed as an MCMC convergence criterion for . Unlike the convergence metric used by which is only dependent on tree topologies, our method is sensitive to branch lengths and therefore provides a more robust metric for convergence. In a test case, it is illustrated that the tropical logistic regression can differentiate between two independently run MCMC chains, even when the standard metric cannot.
Narcissists don’t care about approval: the role of narcissism and status motives in explaining the relationship between self-objectification and approval motivation

Published: July 2024

AbstractPrior research has established that women who self-objectify seek approval from others more strongly than women who self-objectify less. Yet the boundary conditions of this link remain largely unexamined. Building on hierometer theory, which postulates that narcissism tracks social status and motivates status-optimizing behaviour, we tested whether the desire for social status (e.g., among narcissists) severed the association between self-objectification and approval seeking. Two cross-sectional studies (NS1 = 200; NS2 = 201) using moderated mediation models found support for this proposition. The moderated mediation model shows that the link between self-objectification and approval seeking was attenuated among narcissists, as narcissists seek higher social status, instead of favour and approval from others. Together, the studies suggest that self-objectification no longer predicts approval seeking among individuals who prioritise status over inclusion. The findings help further connect the self-objectification literature to research on social status and self-regard. Practical implications and extensions are discussed.

AbstractClimate change is one of the greatest global threats that has ecological, economic, social, and psychological consequences. Nowadays, young people are the target of political agenda since they represent potential future policymakers. Consequently, it is crucial to identify the psychological features that contribute to engagement of young people in climate change issue. This study aimed at identifying and describing different configurations of youth perceiving and experiencing climate change. A sample of 224 participants (61% females; Mage = 21.04, SD = 1.65) were involved in study. From a cluster analysis emerged three distinct profiles, Eco-Disengaged, Eco-Engaged/Oriented and Eco-Engaged/Disoriented, which differ in levels of climate change awareness, worry and anxiety. Findings suggest that institutions might develop green education programs based on young people’s individual differences.
Topische Therapie bei atopischer Dermatitis, Alopecia areata, Vitiligo
Authors: Harpain Lucie 
Published: July 2024

ZusammenfassungDie topische Therapie in der Dermatologie hat sich in den letzten Jahren erheblich weiterentwickelt und bietet neue Hoffnung für Patienten mit verschiedenen Hauterkrankungen wie Atopische Dermatitis (AD), Alopecia areata (AA) und Vitiligo. Bei der Behandlung der AD spielen Basistherapie, topische Steroide und Calcineurin-Inhibitoren eine zentrale Rolle. Die Basistherapie konzentriert sich auf die Stärkung der Hautbarriere. Topische Steroide werden zur kurzfristigen Behandlung von Entzündungsschüben eingesetzt, während topische Calcineurin-Inhibitoren eine Alternative darstellen, insbesondere für empfindliche Hautbereiche. Neue Entwicklungen wie topische PGE4-Inhibitoren und Januskinase(JAK)-Inhibitoren erweitern die Behandlungsoptionen und bieten vielversprechende Ergebnisse für AD-Patienten. Bei der Behandlung der AA sind intraläsionale Kortikosteroid-Injektionen und die Kontaktimmuntherapie wichtige Optionen. Die topische Anwendung von JAK-Inhibitoren wie Tofacitinib und Ruxolitinib hat ebenfalls das Interesse der Forschung geweckt, obwohl ihre Wirksamkeit in Studien divergiert. Die Zulassung der ersten Vitiligo-spezifischen Therapie der Ruxolitinib-Creme durch die EMA (Europäische Arzneimittel-Agentur) im April 2023 markiert einen bedeutenden Fortschritt. Insgesamt zeigen diese Entwicklungen das transformative Potenzial der topischen Therapie und bieten neue Hoffnung für Patienten. Weitere Forschung ist erforderlich, um die langfristige Wirksamkeit und Sicherheit dieser neuen Behandlungsoptionen zu bestätigen und ihr volles Potenzial auszuschöpfen.

AbstractNon-invasive genetic sampling can be used in research, monitoring, and conservation of wild animals to, for example, provide insights into diets, identify individuals and estimate population sizes. Non-invasive genetic sampling may be especially useful to monitor elusive species because DNA can be derived from materials such as hairs and faeces without handling individuals. However, the reliability of the results derived from this technique is dependent on the quality of DNA obtained from samples, which can deteriorate from exposure to environmental conditions and sample age. While freshness of the sample is an important factor, the combined effect of different field conditions on the genotyping success is not fully understood. To address this gap, we systematically investigated the effects of sample age and environmental conditions on genotyping success of faeces, in an experimental setting of four treatments that combined rain and temperature conditions typical of central European climates. We compared the performance of a microsatellite marker set and a SNP panel for red fox (Vulpes vulpes), as well as a microsatellite marker set for pine marten (Martes martes) from faeces resampled over 21 days. We found that genotyping success decreased significantly with sample age, however environmental treatments did not impact the success. Furthermore, the SNPs we used amplified more successfully over time than the respective microsatellites. Therefore, the use of SNPs instead of conventional microsatellites, when using faecal samples for analysis relying on correct amplifications, could be advantageous. We recommend to prioritise the collection of fresh faeces regardless of environmental conditions.
Place Value and Regrouping as Helpful Constructs to Diagnose Difficulties in Understanding the Place Value System
Authors: Jensen Solveig , Gasteiger Hedwig , Bruns Julia 
Published: July 2024

Abstract
The understanding of place value systems, especially the base-ten place value system, is one of the most important prerequisites to develop numeracy. The understanding of place value systems can be ascribed to two concepts, which in the tradition of the German subject-matter didactics are called regrouping principle and place value principle. Our study aims at clarifying whether these two principles can be used systematically for an effective identification of the gaps in students’ understanding to give a basis for individual support. We therefore conducted a study with N = 100 third graders (8 to 10 years old). We asked the students to work on 7 tasks on translating named units into written numbers using the place value system, in which the place value principle, the regrouping principle or both principles had to be considered. We analysed the errors qualitatively regarding which principle was violated and developed a typification of solution behaviour. The identified individual difficulties by taking the perspective of the two principles can be a starting point for individual support. Our tasks are shown to be a quick and easy way to diagnose students’ individual problems in understanding the base-ten place value system.
Liquid carry-over control using three-phase horizontal smart separators in Khor Mor gas-condensate processing plant

Published: July 2024

AbstractLiquid carry-over phenomenon, where liquid droplets escape with gas, is a prevalent operational challenge in gas–liquid separators. Liquid carry-over leads to foaming issue and performance reduction within separator downstream absorption processes. In order to ascertain whether liquid carry-over is inducing foaming within the gas sweetening process’s absorption tower at Iraq’s Khor Mor gas-condensate processing plant, this study initiated an evaluation of the liquid droplet size distribution in the gas product and gas/liquid separation efficiency of upstream Alpha, Bravo #1, Bravo #2, and Charlee separators that feed into the aforementioned tower by using the Horizontal Vessel and ProSeparator correlations in Aspen HYSYS v.11 software. The study revealed that Alpha and Bravo #2 experienced liquid carry-over issues. In response to these challenges, an innovative smart separator design, referred to as an adjustable separator, was proposed, employing the Arnold-Stewart semi-empirical procedure. This design allows for easy adjustment to accommodate changes in feed composition and operational conditions, mitigating the liquid carry-over problem. The smart design demonstrated a significant increase in gas/liquid separation efficiency for Alpha separator, improving by 31.11% under current conditions and 77.65% under future conditions. Similarly, under both current and future conditions, the smart design of Bravo #2 separator yielded an enhancement of 21.31% and 28.23%, respectively. These results suggest that the smart design can be considered an optimal solution for controlling liquid carry-over. This innovation not only maintains high gas/liquid separation efficiency but also prevents foaming, offering a robust solution for ensuring sustained operational performance and productivity in gas–liquid separation processes.
Analysis of changes in shale mechanical properties and fault instability activation caused by drilling fluid invasion into formations
Authors: Zhou Xin , Liu Xiangjun , Liang Lixi 
Published: July 2024

AbstractDuring the drilling process, the issue of drilling fluid loss can lead to changes in the mechanical properties of the formation, thereby altering the stress environment of nearby faults. In order to assess the risk of fault activation during drilling operations, the Ordos M area shale was selected as the research object. Mechanical experiments were conducted on rock samples immersed in water-based drilling fluid with a pressure differential of 2 MPa and a temperature of 50 °C. The changes in the mechanical properties of the shale before and after immersion in drilling fluid were determined. Based on the experimental results, combined with the spring combination model and fault activation theory, a quantitative evaluation of fault activation risk was conducted. The findings revealed that the shale in this region has a high clay content, demonstrating a certain level of water sensitivity. The presence of micro-pores and micro-fractures is well-developed, increasing the interaction probability between drilling fluids and clay minerals. After immersion in drilling fluid, there was a varied decline in all mechanical strengths of the shale. The elastic modulus is positively correlated with the shear strength and Coulomb stress of the fault plane. The Poisson’s ratio is positively correlated with the shear strength and negatively correlated with the Coulomb stress. The greater the internal friction and cohesion, the higher the shear strength of the fault plane, and the larger the friction coefficient, the smaller the Coulomb stress, resulting in a more stable fault.

AbstractThis paper investigates the path-planning problem applied to an innovative Unmanned Air Vehicle teaming with a helicopter to increase safety during Helicopter Emergency Medical Services operations. The unmanned vehicle, a drone that optionally can be launched from the helicopter, has the mission to explore the area of operation to determine the meteorological and environmental conditions and to detect physical obstacles. It is initially found that the combination of probabilistically optimal Rapidly-exploring Random Tree (RRT$$^{*}$$

∗

) as the global planner and of Bidirectional Rapidly-exploring Random Tree (BiRRT) as the local planner provides a nearly optimal global path and a rapid replanning in case new obstacles are detected. Adopting a Savitzky–Golay filter in an optional post-processing phase enables trajectory smoothing, thus improving its practicability. The feasibility of the identified trajectory for a rigid-body helicopter model is assessed by computing a first estimate of attitude, forces, control inputs, and rotor power from the trajectory points and curvature. This assessment shows that the RRT$$^{*}$$

∗

used as a local planner provides replanned trajectories more feasible than BiRRT with comparable computational times.
From an Eco-Relational Approach to Ecologically Responsible Robot Ethics
Authors: Puzio Anna 
Published: July 2024

AbstractIn this reply, I respond to Joshua C. Gellers’ commentary on my article “Not Relational Enough? Towards an Eco-Relational Approach in Robot Ethics” (Puzio, 2024a), in which I present a deeply relational, “eco-relational approach”. This approach asserts that it is necessary to consider the relationality with non-human entities such as animals and technology on a deeper level than has been done in robot ethics so far. This disrupts traditional ethical concepts. In his commentary “Not Ecological Enough: A Commentary on an Eco-Relational Approach in Robot Ethics” (2024), Gellers raises criticisms of my method and the consequences of the eco-relational approach. In this reply, I address these criticisms and focus especially on the ecological responsibility of the eco-relational approach.

Published: July 2024

Abstract

Purpose
Esophageal squamous cell carcinoma (ESCC) is a prevalent tumor in the gastrointestinal tract, but our understanding of the molecular mechanisms underlying ESCC remains incomplete. Existing studies indicate that SUMO specific peptidase 1 (SENP1) plays a crucial role in the development and progression of various malignant tumors through diverse molecular mechanisms. However, the functional mechanism and clinical implications of SENP1 in the progression of ESCC remain unclear.

Methods
Bulk RNA-Sequencing (RNA-seq) was used to compare potential genes in the esophageal tissues of mice with ESCC to the control group. The up-regulated SENP1 was selected. The protein level of SENP1 in ESCC patient samples was analyzed by immunohistochemistry and western blot. The potential prognostic value of SENP1 on overall survival of ESCC patients was examined using tissue microarray analysis and the Kaplan-Meier method. The biological function was confirmed through in vitro and in vivo knockdown approaches of SENP1. The role of SENP1 in cell cycle progression and apoptosis of ESCC cells was analyzed by flow cytometry and western blot. The downstream signaling pathways regulated by SENP1 were investigated via using RNA-Seq. SENP1-associated proteins were identified through immunoprecipitation. Overexpression of Sirtuin 6 (SIRT6) wildtype and mutant was performed to investigate the regulatory role of SENP1 in ESCC progression in vitro.

Results
Our study discovered that SENP1 was upregulated in ESCC tissues and served as a novel prognostic factor. Moreover, SENP1 enhanced cell proliferation and migration of ESCC cell lines in vitro, as well as promoted tumor growth in vivo. Thymidine kinase 1 (TK1), Geminin (GMNN), cyclin dependent kinase 1(CDK1), and cyclin A2 (CCNA2) were identified as downstream genes of SENP1. Mechanistically, SENP1 deSUMOylated SIRT6 and subsequently inhibited SIRT6-mediated histone 3 lysine 56 (H3K56) deacetylation on those downstream genes. SIRT6 SUMOylation mutant (4KR) rescued the growth inhibition upon SENP1 depletion.

Conclusions
SENP1 promotes the malignant progression of ESCC by inhibiting the deacetylase activity of SIRT6 pathway through deSUMOylation. Our findings suggest that SENP1 may serve as a valuable biomarker for prognosis and a target for therapeutic intervention in ESCC.
Impact of multidrug resistance on the virulence and fitness of Pseudomonas aeruginosa: a microbiological and clinical perspective

Published: July 2024

AbstractPseudomonas aeruginosa is one of the most common nosocomial pathogens and part of the top emergent species associated with antimicrobial resistance that has become one of the greatest threat to public health in the twenty-first century. This bacterium is provided with a wide set of virulence factors that contribute to pathogenesis in acute and chronic infections. This review aims to summarize the impact of multidrug resistance on the virulence and fitness of P. aeruginosa. Although it is generally assumed that acquisition of resistant determinants is associated with a fitness cost, several studies support that resistance mutations may not be associated with a decrease in virulence and/or that certain compensatory mutations may allow multidrug resistance strains to recover their initial fitness. We discuss the interplay between resistance profiles and virulence from a microbiological perspective but also the clinical consequences in outcomes and the economic impact.
