Power supplies for microelectronic systems, battery chargers, wind energy applications, electric appliances in the household and dc motor drives require AC-DC converters. The proposed bridgeless Cuk PFC converter in this paper is featured with common ground, transformerless structure, and clear energy delivery process. The absence of bridge rectifiers, transformer and the presence of only two semi
The surging demand for Intelligent Transportation Systems (ITS) to deliver advanced train-related Information for dispatchers and passengers has spurred the development of advanced train delay prediction models. Despite considerable efforts devoted to developing methodologies that can be used to model train operation conditions and produce anticipated train delays, the evaluation strategies for tr
Exceptional are the instances where explicit solutions to optimal control problems are obtainable. Of particular interest are the explicit solutions derived for minimax problems, as they provide a framework for addressing challenges involving adversarial conditions and uncertainties. This thesis presents explicit solutions to a novel class of minimax optimal control problems for positive linear sy
Aim: The aim of this study was to explore the role of managers and employees with an assigned responsibility (i.e. inspirers) when integrating recovery-enhancing activities into everyday work in a primary health care setting. Background: The possibility of recovery during the workday is essential for employee wellbeing. However, the literature on workplace interventions focusing on recovery is sca
However, it is not clear to what extent corresponding perceptual preferences for intonational deviations might rely on listeners’ instrumental expertise or such contextual aspects as the metrical placement of tones. We investigated higher-education music students’ perceptual preferences for melodic intonation of local leading tones in unaccompanied classical violin performances. Recordings of 12 e
Animals communicate with a staggering diversity of rhythmic signals, yet behind all this diversity lies a small number of ethological mechanisms. In this chapter, we provide a quick review of how animal produce rhythmic signals based on these mechanisms, which span tremulation, percussion, bodily displays, stridulation, tymbalation, aerodynamic sound production (including vocalisation), as well as
Nanotechnology offers promising perspectives for revolutionizing agriculture by enhancing productivity and sustainability. Although the global agricultural nanotechnology market was valued at US$ 352.4 billion in 2023 and is estimated to reach US$ 868.9 billion by 2031, concerns about adverse environmental effects persist. This review summarizes the latest developments and perspectives of nanotech
Objectives: This is a protocol for a Cochrane Review (intervention). The objectives are as follows:. To assess the benefits and harms of individualized developmental care interventions for promoting development and preventing morbidity in preterm infants.
Planning and navigation in real-time traffic is challenging, since the driving environment (e.g., road network and infrastructure) is complex and the accurate prediction of surrounding vehicles is hard. To address this, this paper proposes an environment and uncertainty-aware robust motion-planning strategy. The method achieves environment awareness by considering road-geometry constraints in the
In this paper, we present a method for in situ coating of individual protein particles in a respirable size. The aim of the coating was to influence the particle/powder properties, and to reduce or prevent surface-induced conformational changes of the protein, during spray-drying, which was the method used for simultaneously preparing and coating particles. The investigated formulations included b
Businesses play a key role in transforming production and consumption for sustainability,where circular business models (CBMs) offer one solution to reduce waste and rethink resource use.Although CBMs may be able to provide environmental and economic benefits, it is unclear how they canbe implemented effectively and contribute to sustainability goals. To understand how CBMs cancontribute to broade
AimTo fully take advantage of blood test results, comparative data are required. Today, the reference interval is a commonly used concept. This review aims to summarise the current state of reference intervals, focusing on infants.MethodsLiterature on reference percentiles (birth to 12 months of age) published from January 1950 until November 2024 was reviewed. Search terms comprised paediatric, i
Industrial and urban symbiosis (IUS) is an emerging sustainability strategy in which organizations collaborate to optimize resource flows and minimize waste within urban environments. Rooted in circular economy principles, IUS has gained global attention as cities seek innovative solutions to enhance resource efficiency and resilience. However, local authorities play a critical yet underexplored r
Code review is a well-established and valuable software development practice associated with code quality, interpersonal, and team benefits. However, it is also time-consuming, with developers spending 10–20% of their working time doing code reviews. With recent advances in AI capabilities, there are more and more initiatives aimed at fully automating code reviews to save time and streamline softw
The advancement of disease-modifying treatments (DMTs) for Alzheimer's disease (AD), along with the approval of three amyloid-targeting therapies in the US and several other countries, represents a significant development in the treatment landscape, offering new hope for addressing this once untreatable chronic progressive disease. However, significant challenges persist that could impede the succ
