Data-sampled time-varying formation for singular multi-agent systems with multiple leaders.

The time-varying formation problem of singular multi-agent systems under sampled data with multiple leaders is investigated in this paper. Firstly, a data-sampled time-varying formation control protocol is proposed in the current study where the communication among followers merely occurred at sampling instants, which can save the controller communication energy significantly. Secondly, necessary and sufficient conditions for the feasibility of the formation function are provided.

Inkjet-Printed FASnPbI-Based Perovskite Solar Cells.

Metal halide perovskite solar cells (PSCs) have gained significant attention in thin-film photovoltaic research for their high power conversion efficiency (PCE) and facile fabrication processes. This study presents the use of inkjet printing to fabricate thin films of combinatorial mixed formamidinium tin-lead perovskites and evaluates their layer quality and device performance. Our findings demonstrate that incorporating Pb up to 50% into FASnI films enhances lattice stability.

Tactile mechanisms and afferents underlying the rat pup transport response.

Juvenile rodents and other altricial mammals react with calming, immobility, and postural modifications to parental pickup, a set of behaviors referred to as the transport response. Here, we investigate sensory mechanisms underlying the rat transport response. Grasping rat pups in anterior neck positions evokes strong immobility and folding up of feet, whereas more posterior grasping has lesser effects on immobility and foot position.

Augmentation of cognitive-behavioural therapy for obsessive-compulsive and anxiety disorders: a protocol for a systematic review and meta-analysis.

Introduction: While cognitive-behavioural therapy (CBT) for obsessive-compulsive disorder (OCD) and anxiety disorders (ADs) has been proven to be effective and is commonly recommended, a considerable proportion of patients remain symptomatic, do not respond to treatment or discontinue it. Thus, augmentation strategies aimed at enhancing CBT outcomes are essential to reduce the burden of OCD and ADs on patients and society. Various augmentation strategies for CBT in OCD and ADs have been investigated, yet it remains unclear if they show robust beneficial effects beyond first-line CBT.

Public attitudes towards social media field experiments.

The growing use of social media field experiments demands a rethink of current research ethics in computational social science and psychological research. Here, we provide an exploratory empirical account of key user concerns and outline a number of critical discussions that need to take place to protect participants and help researchers to make use of the novel opportunities of digital data collection and field studies. Our primary contention is that we need to elicit public perceptions to devise more up-to-date guidelines for review boards whilst also allowing and encouraging researchers to arrive at more ethical individual study design choices themselves.

Observed carbon decoupling of subnational production insufficient for net-zero goal by 2050.

Historically, economic growth has been closely coupled to carbon emissions responsible for climate change, but to stabilize global mean temperature, net-zero carbon emissions are necessary. Some economies have begun to reduce emissions while continuing to grow, but this decoupling is not fast enough to achieve global climate targets. Subnational climate actions seem to be crucial for the achievement of these targets.

Identification of a Specific Granular Marker of Zebrafish Eosinophils Enables Development of New Tools for Their Study.

Eosinophils control many aspects of the vertebrate innate immune response. They contribute to homeostasis, inflammatory conditions and defense against pathogens. With the varied functions of eosinophils, they have been found to play both protective and pathogenic roles in many diseases.

The Best DFT Functional Is the Ensemble of Functionals.

The development of better density functional theory (DFT) methods is one of the most active research areas, given the importance of DFT for ubiquitous molecular and materials simulations. However, this research primarily focuses on improving a specific exchange-correlation Kohn-Sham density functional. Here, a robust procedure is proposed for constructing transferable ensembles of density functionals that perform superior to any constituent individual density functional.

Men and women transitioning to singlehood in young adulthood and midlife.

Research has long shown that men suffer more from romantic breakups than women. We predicted that men would on average be less inclined to initiate separation, decline with the separation more in well-being and increase more in loneliness, are less satisfied with singlehood, and desire a new partner more than women. We theorized that these gender differences in separation adaptation could be linked to men's higher reliance on their partners for emotional support.

Delving into South China Sea microplastic pollution: Abundance, composition, and environmental risk.

Understanding marine pollution in the South China Sea is crucial for preserving marine ecosystems and biodiversity. Despite extensive research on pollutants, there is a significant gap in knowledge about microplastics (MPs) in the archipelago region. This study focused on four typical islands, examining MPs in seawater and sediments, their distribution, and environmental risks.

Harmonize rules for digital sequence information benefit-sharing across UN frameworks.

As multiple UN fora develop parallel rules for sharing benefits from digital sequence information, we urge better coordination. International policymakers should focus on harmonizing new benefit-sharing rules to ensure open access to data, database interoperability, and better benefit sharing outcomes.

Improvements in executive functions by domain-specific cognitive training in youth elite soccer players.

This study examined the impact of sport-specific cognitive training (CT) on executive functions (EFs) in youth soccer players. Thirty-one athletes (13-15 years) participated, 13 in the intervention group (IG) and 18 in the control group (CG). The IG underwent an 8-week soccer-focused CT program, while the CG maintained regular training.

Prospectively investigating the impact of AI onshared decision-making in post kidney transplant care (PRIMA-AI): protocol for a longitudinal qualitative study among patients, their support persons and treating physicians at a tertiary care centre.

Introduction: As healthcare is shifting from a paternalistic to a patient-centred approach, medical decision making becomes more collaborative involving patients, their support persons (SPs) and physicians. Implementing shared decision-making (SDM) into clinical practice can be challenging and becomes even more complex with the introduction of artificial intelligence (AI) as a potential actant in the communicative network. Although there is more empirical research on patients' and physicians' perceptions of AI, little is known about the impact of AI on SDM.

Resolving biology's dark matter: species richness, spatiotemporal distribution, and community composition of a dark taxon.

Background: Zoology's dark matter comprises hyperdiverse, poorly known taxa that are numerically dominant but largely unstudied, even in temperate regions where charismatic taxa are well understood. Dark taxa are everywhere, but high diversity, abundance, and small size have historically stymied their study. We demonstrate how entomological dark matter can be elucidated using high-throughput DNA barcoding ("megabarcoding").

Narratives of contingency and practices of comparing in the emergence of German molecular genetics (1958-1968).

This article explores the emergence of molecular approaches in German genetic research during the 1958-1968 decade as a period of contingency and alternative possibilities. We introduce "Narratives of Contingency" as an analytical framework to examine how scientists construct a specific narrative - linking past experiences with expectations of future conditions - in order to outline and navigate pathway-decisions in the present. We apply this framework to Hans-Jörg Rheinberger's developmental model of molecular genetics and illustrate how the stages he identifies - the direction of the field, institutional developments, and epistemological demarcations - were already central themes in the comparative practices underlying narratives of contingency in this early period.

Defining key concepts for mental state attribution.

The terminology used in discussions on mental state attribution is extensive and lacks consistency. In the current paper, experts from various disciplines collaborate to introduce a shared set of concepts and make recommendations regarding future use.

Tactile Mechanisms and Afferents Underlying the Rat Pup Transport Response.

Juvenile rodents and other altricial mammals react with calming, immobility and folding up of feet to parental pickup, a set of behaviors referred to as transport response. Here we investigate sensory mechanisms underlying the rat transport response. Grasping rat pups in anterior neck positions evokes strong immobility and folding up of feet, whereas more posterior grasping positions have lesser effects on immobility and foot position.

Interplay of physical and recognition performance using hierarchical continuous-time dynamic modeling and a dual-task training regime in Alzheimer's patients.

Unlabelled: Training studies typically investigate the cumulative rather than the analytically challenging immediate effect of exercise on cognitive outcomes. We investigated the dynamic interplay between single-session exercise intensity and time-locked recognition speed-accuracy scores in older adults with Alzheimer's dementia ( = 17) undergoing a 24-week dual-task regime. We specified a state-of-the-art hierarchical Bayesian continuous-time dynamic model with fully connected state variables to analyze the bi-directional effects between physical and recognition scores over time.

Fertility after photodynamic inactivation of bacteria in extended boar semen.

Antimicrobial resistance is an increasing challenge in semen preservation of breeding animals, especially in the porcine species. Bacteria are a natural component of semen, and their growth should be inhibited to protect sperm fertilizing capacity and the female's health. In pig breeding, where semen is routinely stored at 17°C in the liquid state, alternatives to conventional antibiotics are urgently needed.

Seasonal soil health dynamics in soy-wheat relay intercropping.

There is growing interest in intercropping as a practice to increase productivity per unit area and ecosystem functioning in agricultural systems. Relay intercropping with soy and winter wheat may benefit soil health due to increased diversity and longer undisturbed soil cover, yet this remains largely unstudied. Using a field experiment in Eastern Germany, we studied the temporal dynamics of chemical, biological, and physical indicators of soil health in the topsoil over a year of cultivation to detect early effects of soy-wheat relay intercropping compared to sole cropping.
