We introduce the concept of cyclicity and hypercyclicity in self-similar groups as an analogue of cyclic and hypercyclic vectors for an operator on a Banach space. We derive a sufficient condition for cyclicity of non-finitary automorphisms in contracting discrete automata groups. In the profinite setting we prove that fractal profinite groups may be regarded as measure-preserving dynamical system

Climate policies are challenged around the world, a development coinciding with the backlash of globalisation. The emergence of the modern welfare state, however, indicates that similar tensions may give rise to transformative change, if coinciding interests for change develop. This article explores the case of Sweden, critical due to its longstanding role as an environmental frontrunner, now expe

Cemented carbides with tungsten carbide grains as hard phase and metallic cobalt binder phase are used extensively for drill bit inserts for rock drilling. The process of rock drilling is severe with some of the wear happening through fracture in the cemented carbide. This work investigated two cemented carbides with iron rich alternative binder phases containing different amounts of FCC phase, in

This study is aimed at detecting Parkinson's disease by analyzing voice measurements made using a mobile phone. The key objectives include creating a model that ensures accurate predictions while maintaining interpretability, consistent with the existing literature on Parkinson's disease. We introduce a novel group-wise scaling method to address typical age and biological sex biases in the dataset

Indoor sensing is challenging because of the multi-bounce effect, spherical wavefront, and spatial nonstationarity (SNS) of the near-field effect. This paper addresses radio-based environment sensing considering these issues. Specifically, graph theory (GT) is used to model the multi-bounce propagation of the near field. In this manner, indoor reflectors/scatterers are modeled as vertices in a pro

Ovarian cancer (OvCa) is a leading cause of gynecological cancer-related mortality, primarily due to peritoneal dissemination, which facilitates metastasis in the abdominal cavity. This study explored the potential of vitamin D and its synthetic derivatives in mitigating peritoneal dissemination by modulating the behavior of mesothelial cells (MCs). Vitamin D, through its receptor (VDR), is known

Small and middle states such as Canada have been integrating drones into their militaries for over 20 years, but their drone use has been understudied. Delving into the data from interviews with 33 army drone operators, this paper proposes two arguments about how drone operators negotiate their identity-based reflections on their roles. First, the paper argues that drone operators in the Canadian

This study investigated the spatial dynamics of bark beetle infestations and their relationships with risk factors in south-eastern Swedish forests during the years 2018–2020, highlighting the importance of spatial heterogeneity of risk factors, particularly under climate change. First, global Random Forest (RF) models were developed to examine the relationships between bark beetle infestations an

A key critique of urban planning in postcolonial contexts is the persistence of Western/Eurocentric approaches that disregard the spatial production of Black and Indigenous populations as legitimate. In Brazil, despite shifts from authoritarian to democratic governments, racialised territories have consistently been subjected to state intervention. While policies have evolved—from deregulation and

“United by Music” was the slogan of the 2024 edition of the Eurovision Song Contest, held in Malmö. However, the festive spirit of the event oddly contrasted with what was described as “the largest police operation in Sweden’s history” (Ivarsson, 2024). This operation was mobilized in response to the expected civil protests regarding Eurovision’s decision to welcome Israel’s participation, despite

ImportanceSyncope remains a diagnostic challenge despite advancements in testing and treatment. Cardiac syncope is an independent predictor of mortality and can be difficult to distinguish from other causes of transient loss of consciousness (TLOC).ObservationsThe cause of TLOC is often unclear, hospitalization criteria are ambiguous, diagnostic tests are frequently non-informative, and assessment

Adaptiv återanvändning, det vill säga konvertering av befintliga byggnader till nya funktioner, utgör ett hållbart alternativ till rivning och nybyggnation genom att minska miljöpåverkan, bevara material och reducera kostnader. Föreliggande studie utgör den första storskaliga och systematiska analysen av adaptiv återanvändning i Sverige, baserad på energideklarationer (EPC) från 141 778 byggnader Adaptive reuse, the conversion of existing buildings to new functions, offers a sustainable alternative to demolition and new construction by reducing environmental impact, conserving materials, and minimising costs. This study presents the first large-scale, systematic analysis of adaptive reuse in Sweden, using Energy Performance Certificates (EPCs) from 141 778 buildings issued between 2007 and

BackgroundAs primary health care forms the basis of the health care system, it is regarded as an efficient way to address main causes of, and risk factors for, poor health. In the Swedish health care system, general practitioners play a role in facilitating access to specialized health care and in coordinating care from other parts of the health care system. In Sweden, recent marketization efforts

Aim: While diabetes mellitus (types 1 and 2) is known to negatively impact vestibular and auditory function, the precise mechanisms underlying this effect are not fully understood. Building on our previous findings, which demonstrated the presence of insulin signaling components within the human saccule and identified the sodium transporter ENaC as a target for insulin signaling in HEI-OC1 auditor
