Lead-free perovskite nanocrystals (NCs) were obtained mainly by substituting a Pb2+ cation with a divalent cation or substituting three Pb2+ cations with two trivalent cations. The substitution of two Pb2+ cations with one monovalent Ag+ and one trivalent Bi3+ cations was used to synthesize Cs2AgBiX6 (X=Cl, Br, I) double perovskite NCs. Using femtosecond transient absorption spectroscopy, the char

Themembers of the paired box (Pax) family regulate key developmental pathways inmanymetazoans as tissue-specific transcription factors. Vertebrate genomes typically possess nine Pax genes (Pax1–9), which are derived from four proto-Pax genes in the vertebrate ancestor that were later expanded through the so-called two-round (2R) whole-genome duplication. A recent study proposed that pax6a genes of

OBJECTIVE: A novel extended-wavelength diffuse reflectance spectroscopy (EWDRS) technique is being developed for future clinical non-invasive tumor margin delineation. In this study, the ability of EWDRS to identify the margins of pigmented skin lesions in an in vivo pig model was evaluated.MATERIALS AND METHODS: Extended-wavelength diffuse reflectance spectroscopy recordings (350-1550 nm) were ma

Background: Whole genome sequences have allowed us to have an overview of the evolution of gene repertoires. The target of the present study, the TGFβ superfamily, contains many genes involved in vertebrate development, and provides an ideal system to explore the relationships between evolution of gene repertoires and that of developmental programs.Results: As a result of a bioinformatic survey of

Heavy metals are some of the most persistent and potent anthropogenic environmental contaminants. Although heavy metals may compromise microbial communities and soil fertility, it is challenging to causally link microbial responses to heavy metals due to various confounding factors, including correlated soil physicochemistry or nutrient availability. A solution is to investigate whether tolerance

A novel mobile laser radar system was used for mapping gaseous atomic mercury (Hg0) atmospheric pollution in the Wanshan district, south of Tongren City, Guizhou Province, China. This area is heavily impacted by legacy mercury from now abandoned mining activities. Differential absorption lidar measurements were supplemented by localized point monitoring using a Lumex RA-915M Zeeman modulation merc

Objectives: The aim was to evaluate the association between serum Anti-Müllerian Hormone (AMH) level and cumulative live birth rates (LBR) in patients undergoing their first in vitro fertilization (IVF) treatment cycle, and to compare serum AMH levels with Antral Follicle Count (AFC) and Ovarian Sensitivity Index (OSI) as predictors of live birth. Study design: A prospective cohort study of 454 pa

Microvascular changes have recently been described for several neurodegenerative disorders, including Huntington's disease (HD). HD is characterized by a progressive neuronal cell loss due to a mutation in the Huntingtin gene. However, the temporal and spatial microvascular alterations in HD remain unclear. Also, knowledge on the implication of pericytes in HD pathology is still sparse and existin

A nanosized hydroxyapatite (HA) modification on polyetheretherketone (PEEK) using a novel spin coating technique was investigated in a rabbit model. Spin coating technique creates a 20–40 nm thick layer of nanosized HA particles with similar shape, size, and crystallinity as human bone. Some implants were designed with a perforating hole in the apical region to mimic a fusion chamber of a spinal i

Growing globalisation and climate change are challenging the sustainability of our societies. It is now clear that climate change and its devastating impacts cannot be resolved by new technology or governance alone. They require a broader, cultural shift. As a result, the role of human beings' ‘inner dimensions’ and related transformations is attracting increased attention from researchers. Recent

Ribs are widely employed in internal cooling passages of turbine blades and other heat transfer equipment to enhance heat transfer by making cooling air flow through internal ribbed passages. From mathematics, a fractal is an abstract object used to simulate naturally occurring objects, which exhibits similar patterns and properties also at smaller scales. The evolving fractal structures of the co

We analyse the effect of business model innovation (BMI) on the product innovation performance of firms, based on a dynamic capabilities theoretical framework. Our empirical study is based on a large-scale representative sample of cross-industry Swedish firms participating in three waves of the Community Innovation Survey (CIS) from 2008 to 2012. We hypothesise that BMI in the form of product inno

En handskrift som en gång tillhörde Alvastra kloster, nu Uppsala Universitetsbibliotek C 37, innehåller en delvis kalendariskt ordnad predikosamling nedskriven i början av 1200-talet, utan kända paralleller. Artikeln beskriver samlingen och konstaterar att innehållet har både monastisk och folklig prägel. En möjlig slutsats är att en munk i Alvastra har sammanställt/författat predikningarna för at

The development of MIMO over-the-air (OTA) test methodology is an ongoing activity in 3GPP RAN4, CTIA and EU COST Action 2100. In this paper, the focus is on the anechoic chamber approach, which uses a uniform circular array of probe antennas to replicate directional channels for the device-under- test at the array center. In particular, we study in simulation the complexity requirements of implem

History and archaeology have a well-established engagement with issues of premodern societal development and the interaction between physical and cultural environments; together, they offer a holistic view that can generate insights into the nature of cultural resilience and adaptation, as well as responses to catastrophe. Grasping the challenges that climate change presents and evolving appropria

Objectives/Hypothesis: TNM-classification inadequately estimates patient-specific overall survival (OS). We aimed to improve this by developing a risk-prediction model for patients with advanced larynx cancer. Study Design: Cohort study. Methods: We developed a risk prediction model to estimate the 5-year OS rate based on a cohort of 3,442 patients with T3T4N0N+M0 larynx cancer. The model was inte

The incidence of pancreatic cancer is leveling between sexes. Smoking, high age and heredity are established risk factors, but evidence regarding the influence of hormonal factors is unclear. In this study, we investigated the associations of reproductive factors, use of oral contraceptives (OC) and hormone replacement therapy (HRT) with pancreatic cancer risk in the Malmö Diet and Cancer Study, a
