Studies in temperate systems provide evidence that the abundance of arbuscular mycorrhizal fungal (AMF) depends on soil nutrient availability, which is mainly explained in the context of resource stoichiometry and differential plant biomass allocation. We applied this concept to an understudied ecosystem - tropical montane forest - analyzing root and AMF abundance along an elevational gradient wit
Deforestation and the use of fire to clear land have drastic effects on ecosystem functioning and compromise essential ecosystem services, especially in low-income tropical countries such as Madagascar. We evaluated the effects of local slash-and-burn practices on soil nutrients and arbuscular mycorrhizal (AM) fungi abundance in a southwestern Madagascar forest. Nine sampling plot pairs were estab
Objective: Enhancing the reliability of myoelectric controllers that decode motor intent is a pressing challenge in the field of bionic prosthetics. State-of-the-art research has mostly focused on Supervised Learning (SL) techniques to tackle this problem. However, obtaining high-quality labeled data that accurately represents muscle activity during daily usage remains difficult. We investigate th
This paper presents a decentralized strategy for a team of N robotic manipulators cooperatively grasping and manipulating an object. A two-step strategy has been designed. In the first step, each robot runs N − 1 consensus-based estimators to estimates the wrenches applied to the object by its teammates even when direct all-to-all communication is unavailable. In the second step, each manipulator
This paper addresses the time-optimal path-tracking problem for redundant manipulators. By integrating path-velocity control into existing task-space robot controllers, the task-space motion can be dynamically scaled to satisfy the torque constraint under both kinematic and dynamic uncertainties. Numerical simulations and experiments demonstrate that trajectory feasibility and path-tracking accura
BACKGROUND: Children, adolescents, and young adults with cancer (referred to as CAYAs) are at risk of long-term health complications, with cardiovascular disease (CVD) being a major concern. In addition, sociodemographic characteristics and traditional cardiovascular risk factors may also contribute to disparities in outcomes compared with those of the general population. The aim of this study was
Denna avhandling undersöker oberoende kulturproduktion som idé(al) och fenomen, särskilt den centrala roll som samarbeten och ömsesidiga beroenden har för oberoende kulturaktörer. Samtida oberoende kulturproduktion både tillåter och kräver organisering i ett spänningsfält av olika förväntningar och begränsade rumsliga, finansiella och mänskliga resurser. I en tid av allt starkare politisk motvind,This thesis engages with the phenomenon of independent cultural production, which empirically shows itself as an idea(l) of self-determined cultural production and collaboration made possible through numerous different relationships. Independence, as a relational concept, achieved through in(ter)dependencies is what this thesis sets out to explore. Definitions of independence in cultural productio
At the fifth session of the United Nations (UN) Environment Assembly in March 2022, UN member states were mandated to negotiate an international, legally binding instrument on plastic pollution. This article assesses pre-session submissions from the second and third negotiation rounds to identify proposed measures and priorities for the treaty. The analysis, employing systematic qualitative conten
Phosphorus deficiency exacerbates the challenges of phytoremediation in mining areas, particularly for herbaceous species. Although Melilotus officinalis L. Pall. (Melilotus) serves as a pioneer species in mine reclamation, its response mechanisms to phosphorus deficiency stress (PDS)—particularly regarding root exudates composition, plant growth, soil properties, and key microbial functional grou
The temporality of global value chains is an important area of concern for economic geographers. This paper argues for the analytical value of closely examining the category of ‘turnover time’ as articulated in Marx’s work and subsequent historical-geographical materialism. We argue that turnover times of capitals in competition – hence struggles over time – can be conceptualised as a driving forc
Universities, operating at the intersection of state, market, and civil society, are increasingly called upon to address urgent global challenges, such as climate change, inequalities, and social injustice. This has given rise to hybrid roles for scholars, ranging from public intellectuals to policy advisers and academic entrepreneurs. Among these roles, scholar-activism stands out by explicitly a

Precision-cut lung slices (PCLS) have gained increasing interest as a model to study lung biology and disease, as well as for screening novel therapeutics. In particular, PCLS derived from human tissue can better recapitulate some aspects of lung biology and disease as compared to PCLS derived from animals (e.g. clinical heterogeneity), but access to human tissue is limited. A number of different
In this paper I investigate the petitions to invalidate forced marriages submitted to the Apostolic Penitentiary during the pontificate of Pope Innocent VIII (1484-1492). The supplications will be analyzed both in relation to the late medieval scholarly discussion of force and fear as impediment to marriage, and in relation to the lived reality that emerges in the petitioner’s narratives. The Peni
Single cell sequencing technologies (scRNA-seq, scATAC-seq, etc.) have revolutionized the study of complex tissues and unique organisms, providing researchers with a much needed species agnostic tool to study biological processes at the cellular level. To date, scRNA-seq technologies are expensive, require sufficient cell quantities, and need biological replicates to avoid batch effects or artifac
Background: Dementia is a global public health challenge, with Alzheimer's disease (AD) and vascular dementia (VaD) being the most prevalent subtypes. Air pollution is a potential risk factor for dementia, but few studies separate AD and VaD. Objective: This study aims to investigate whether exposure to air pollution is associated with the incidence of AD and VaD. Methods: This study involved 30,2
