We consider the balayage of a measure μ defined on a domain Ω onto its boundary ∂Ω. Assuming that Ω has a corner of opening πα at a point z₀ ∈ ∂Ω for some 0 < α ≤ 2 and that dμ(z) ≅ |z - z₀|²ᵇ⁻² dz² as z → z₀ for some b > 0, we obtain the precise rate of vanishing of the balayage of μ near z₀. The rate of vanishing is universal in the sense that it only depends on α and b. We also treat the case w

Symbioses can be vital on islands, where low species diversity leaves few alternative partners and the failure of associations can cascade into broader community collapse. Key to the functioning of many island ecosystems is the rainforest tree, Pisonia grandis (pisonia). Pisonia attracts nesting seabirds whose guano delivers intense nutrient pulses that fuel coral reef ecosystems. Symbiotic mycorr

The scale of the 21st-century urban housing challenge has prompted state actors in both the Global North and South to adopt increasingly interventionist approaches to ‘affordable’ housing production. This article draws on research in six cities (Shanghai, Nairobi, Paris, Casablanca, Salford and Rome) to discuss the changing relationship between housing, finance and the state through a global compa

The next generation wireless systems will face stringent new requirements, including ultra-low latency, high data rates and enhanced reliability. Large Intelligent Surfaces, is one proposed solution that has the potential to solve these high demands. The real-life deployment of such systems involves different design considerations with non-trivial trade-offs. This paper investigates the trade-off

Plastic pollution poses urgent environmental, societal, and health challenges, yet governance remains fragmented. The 2022 UNEA resolution 5/14 offers an opportunity for a legally binding treaty, but negotiations are stalled by geopolitical tensions, entrenched industrial interests, and divergent views on the plastic problem. Effective governance is further constrained by knowledge gaps spanning tPlastic pollution poses urgent environmental, societal, and health challenges, yet governance remains fragmented.

Strategies that enable ignition of the low cetane alcohol fuels (methanol and ethanol) include intake heating (direct or via hot residual trapping), increased compression ratio (CR), multi-injection strategies, ignition enhancers, and active prechambers. The literature consistently shows alcohol compression ignition (CI) is more efficient than diesel at high loads irrespective of ignition strategy

Single-stranded RNA viruses co-assemble their capsid with the genome, and variations in capsid structures can have significant functional relevance. In particular, viruses need to respond to a dehydrating environment to prevent genomic degradation and remain active upon rehydration. Theoretical work has predicted low-energy buckling transitions in icosahedral capsids, which could protect the virus

Following Russia’s full-scale invasion in 2022, Ukraine has adopted innovative communication strategies to build and sustain Western support. Among these is the prominent visibility of LGBT+ soldiers in Ukrainian strategic communication, which links military heroism, LGBT+ rights and national survival. This article explores how the digital self-narration of Ukrainian LGBT+ service members and spok

The fourth United Nations High-Level Meeting on the Prevention and Control of Noncommunicable Diseases (NCDs) and Promotion of Mental Health and Well-Being developed a timely Political Declaration intended to accelerate progress among Member States towards the targets of Sustainable Development Goal 3.4. The Declaration emphasises appropriate cross-cutting actions for prevention and control of NCD

In a context where scientific communication is caught be-tween the for-profit motives of large publishers and the need for democratized knowledge, the journal Ecosistemas reaffirms its commitment to a publication model that is, above all, by the scientific community and for the scientific community. We are not only consolidating our vision, but also taking firm steps toward a new stage of mod

Background: Climate change poses an escalating threat to global brain health and is increasingly linked to stroke incidence, outcomes, and inequities in prevention and treatment. This World Stroke Organization scientific statement summarizes current evidence on the associations between stroke and the environmental variables exacerbated by climate change, with a focus on risk and outcomes. Methods:

Machine learning algorithms for myoelectric pattern recognition require substantial user-specific training data, limiting broader applications of electromyography (EMG) in human–computer interfacing. Here, we present a framework for EMG-mediated motor intent decoding designed to function for new users without collecting user-specific training data. We introduce a Transformer-based architecture, te

Most forensic psychiatric patients are diagnosed with schizophrenia or schizoaffective disorder. Psychotherapy is recognized as an important part of treatment for this patient population, yet no clinical guidelines exist. This mixed-method systematic review aimed to evaluate the scope, quality, and findings of psychotherapy research involving this population. Following the Joanna Briggs Institute

Introduction: Oxidating fat as an energy substrate requires more oxygen than utilizing carbohydrates and can be acutely increased by hyperoxia. Therefore, substrate utilization may affect endurance performance and gas consumption in divers, but previous research is limited. This study aimed to evaluate changes in maximal fat oxidation (MFO) in navy divers during training. Methods: Seven explosive

Peripartum hysterectomy (PH), the surgical removal of the uterus during the peripartum period, is a rare but potentially life-saving intervention for severe obstetric complications such as major haemorrhage, uterine rupture, and placenta accreta spectrum (PAS). As a maternal near-miss event, PH carries substantial maternal and neonatal morbidity, mortality, and long-term psychological impact. Data

Sex differences in cutaneous melanoma (CM) survival are pronounced. It is unclear how these differences impact the loss in life expectancy (LLE). A population-based cohort from the Swedish Melanoma registry was used to analyze sex differences in life expectancy (LE) and LLE following a CM diagnosis. The cohort included 12,893 men and 12,572 women aged 40 years or above diagnosed with a first invas
