Multi-variable compensated quantum yield measurements of upconverting nanoparticles with high dynamic range : a systematic approach

Non-linear materials such as upconverting nanoparticles (UCNPs) are emerging technology with fast-growing applications in various fields. The power density dependence of the emission quantum yield (QY) of these non-linear materials makes them challenging to characterize using currently available commercial QY systems. We propose a multimodal system to measure QY over a wide dynamic range (1:104),

Immunity to Rotavirus infection across ages

Rotavirus (RV) is a double-stranded RNA virus that mainly affects young children under the age of five years. It is one of the leading causes of dehydrating gastroenteritis. Every year, about 200,000 child deaths occur due to RVinfection. Vaccines exist and are in use worldwide. However, these vaccines' efficacy is relatively low in countries where deaths due to the virus are high.The aim of the w

Phonetic and Phonological Variation in Vowel Discrimination Performance : Effect of Swedish Vowel Categories and Dialects

Acoustic discrimination of speech sounds is affected by various factors, ranging from more universal acoustic properties of categories to the phoneme systems of the native language and dialect, and even influences from languages learned later in life. A discrimination experiment containing East Central Swedish vowels was carried out with 30 native Swedish listeners in order to explore the variatio

Effects of print orientation on the design of additively manufactured bio-based flexible lattice structures

In upholstery applications, it is common to use polyurethane (PUR) foam when flexibility is desired. However, as PUR is a carbon-based material produced using toxic isocyanates, it is environmentally beneficial to replace PUR with bio-based alternatives. The challenge, however, lies in finding suitable bio-based replacement materials, capable of mimicking the foam-like functionality of PUR since m

Childhood Height Growth Rate Association With the Risk of Islet Autoimmunity and Development of Type 1 Diabetes

Context: Rapid growth has been suggested to promote islet autoimmunity and progression to type 1 diabetes (T1D). Childhood growth has not been analyzed separately from the infant growth period in most previous studies, but it may have distinct features due to differences between the stages of development. Objective: We aimed to analyze the association of childhood growth with development of islet

GPC1 (glypican 1)

Review on GPC1, with data on DNA/RNA, on the protein encoded and where the gene is implicated.

Auditory Processing of the Brain Is Enhanced by Parental Singing for Preterm Infants

As the human auditory system is highly malleable in infancy, perinatal risk factors, such as preterm birth, may affect auditory development. In comparison to healthy full-term infants, preterm infants show abnormal auditory brain responses at term age, which may have long-term detrimental outcomes. To achieve an optimal neonatal care environment for preterm-born infants, many early interventions h

Cross-cultural supervision amidst a generational shift

This paper sets out to draw on my experience as a Sweden-based academic supervisor who is also active in Poland to reflect on the issue of cross-cultural supervision amidst a presumed generational shift that goes on in Poland. Split between stories of a destructive hierarchy and non-transparency in Polish academia on the one hand, and of an emergent “West-minded” reorientation on the other, this p

Improving poly(arylene piperidinium) anion exchange membranes by monomer design

Energy conversion devices such as alkaline membrane fuel cells and water electrolyzers rely critically on durable anion exchange membranes (AEMs) with high hydroxide conductivity. In this context, poly(arylene piperidinium)s have emerged as one of the top candidate materials. Here, we report on the preparation and properties of poly(arylene alkylene piperidinium)s (PAAPs) with significantly higher
