The ever-growing reliance on electronic devices and the burgeoning field of green energy necessitate efficient and different gain AC-DC converters for a myriad of applications, from electric drives to solar cells and grid-connected inverters. This paper introduces a hybrid closed-loop bridged and bridgeless Single-Ended Primary-Inductor Converter (SEPIC) topologies featuring switched-capacitor net
Hospitals were among the wealthiest organizations in medieval cities. Their directors managed portfolios consisting of real estate and financial instruments; as a result, they also handled large quantities of money. It has been suggested that they used these to provide a variety of financial services and performed early banking functions. In this study I focus on the role hospitals played in allow
This study develops a strategic framework to guide the adoption of Industry 4.0 technologies across various business sectors. Using a mixed-methods approach, the research combines an extensive literature review with empirical investigations, including case studies and surveys with industry practitioners. The framework integrates advanced digital technologies, such as artificial intelligence and im
This paper presents a methodology for estimation of physically interpretable building energy performance characteristics such as: heat loss coefficient, azimuth angle dependent solar gain, and diurnal periodicity in heat-demand. The models are demonstrated on a case-study with hourly observations of district-heating connected apartment buildings in Denmark. The weather model inputs are obtained fr
The possibility that albatrosses use a geomagnetic bi-coordinate map for long-distance navigation at sea was investigated by evaluating how five different geomagnetic parameters (i.e. total field intensity, horizontal and vertical field intensity, inclination and declination) vary in areas where foraging albatrosses have been recorded by satellite telemetry in the Southern Ocean. Our objective was
Serial crystallography (SX) at both X-ray free-electron lasers (XFELs) and synchrotrons offers the possibility to collect data at non-cryogenic temperature almost radiation damage free and enables time-resolved crystallography of irreversible reactions. The necessary steady delivery of new micron-sized crystals of biological macromolecules sets it apart from traditional single crystal macromolecul
The maker movement has reached the optics labs, empowering researchers to create and modify microscope designs and imaging accessories. 3D printing has a disruptive impact on the field, improving accessibility to fabrication technologies in additive manufacturing. This approach is particularly useful for rapid, low-cost prototyping, allowing unprecedented levels of productivity and accessibility.
Drawing on vignette interviews, this article analyses the legal consciousness of disability anti-discrimination law of staff working with disability/accessibility resources in higher education in Sweden and the United States. In both countries, participants considered the law as the basis of their work, but differences were noticed regarding their views of the purpose of laws banning disability di
Stem cells are unique, undifferentiated cells that have the ability to both replicate themselves and develop into specialized cell types. This dual capability makes them valuable in the development of regenerative medicine. Current development in stem cell research has widened their application in cell therapy, drug discovery, reproductive cloning in animals, and cell models for various diseases.
Mobile stroke units (MSUs), which are specialized ambulances equipped with a brain imaging device and staffed with trained healthcare personnel, have the potential to provide rapid on-site diagnosis and treatment for stroke patients. However, efficient access to prehospital stroke care requires optimizing the placement of MSUs. The MSU allocation problem has been previously solved using a traditio
A new microphysical treatment that includes aerosol–cloud interactions and secondary ice production (SIP) mechanisms is implemented in the convection scheme of the Community Atmosphere Model, version 6 (CAM6). The approach is to embed a 1D Lagrangian parcel model in the bulk convective plume of the existing deep convection parameterization. Aerosol activation, growth processes including collision/
To address the pressing challenge of decarbonizing heavy-duty transportation, this thesis explores advanced combustion strategies using sustainable gaseous fuels, specifically hydrogen and methane, in internal combustion engines (ICEs). While electrification remains difficult to implement in long-haul applications due to energy density and infrastructure limitations, this work identifies and refin
We developed an algorithm for the early screening of autism spectrum disorder using baby cry sound. We collected the sound using a smartphone application to record it in their daily life. We employed the Japanese version of the Modified Checklist for Autism in Toddlers (M-CHAT) for the evaluation of the autism spectrum. We built a prediction model for binary classification using least absolute shr

Archaeologists create vast amounts of specialized data, which are often difficult to access, maintain, and reuse, even for practitioners themselves. In this article, we explore the implication of professional practices of data production in fueling archaeonormativity—i.e., the naturalization of behaviors and structures in archaeology that strip it of affect and meaning and that deny human (and non
Aims. The aim of this study is to provide radiative data for neutral and singly ionised silicon, in particular for the first experimental oscillator strengths for near-infrared Si I lines. In addition, we aim to perform atomic structure calculations both for neutral and singly ionised silicon while including lines from highly excited levels. Methods. We performed large-scale atomic structure calcu
