Background: High breast density is a risk factor for breast cancer. However, whether density is a prognostic factor is debatable. Also, tumor appearances are related to tumor characteristics. Here we investigate the relationship between breast cancer-specific survival and mammographic breast density and mammographic tumor appearances. Methods: Women in the Malmö Diet and Cancer study with invasive

INTRODUCTION: The Five Self-Harm Behavior Groupings Measure (5S-HM) is a novel assessment that evaluates behaviours which may go undetected by existing measures. Self-harm is formulated across directness and lethality spectra, including under-studied behaviors such as indirect self-harm, harmful self-neglect and sexual self-harm. Aims of the study were to: (1) empirically evaluate the 5S-HM; (2) t

In polaritons, the properties of matter are modified by mixing the molecular transitions with light modes inside a cavity. Resultant hybrid light-matter states exhibit energy level shifts, are delocalized over many molecular units, and have a different excited-state potential energy landscape, which leads to modified exciton dynamics. Previously, non-Hermitian Hamiltonians have been derived to des

Reducing the excitation threshold to minimize the Joule heating is critical for the realization of perovskite laser diodes. Although bound excitons are promising for low threshold laser, how to generate them at room temperature for laser applications is still unclear in quasi-2D perovskite-based devices. In this work, via engineering quasi-2D perovskite PEA2(CH3NH3)n-1PbnBr3n+1 microscopic grains

This study aims to investigate and disentangle the impact of land use and climate variability on the Baltic Sea coastal zone from a millennial perspective. To assess the environmental status of the coastal zone we make use of siliceous microfossils (mainly diatoms), stable nitrogen and carbon isotopes, organic carbon accumulation rates, and lithological changes analyzed in a sediment core collecte

Obesity and cardiometabolic disease often, but not always, coincide. Distinguishing subpopulations within which cardiometabolic risk diverges from the risk expected for a given body mass index (BMI) may facilitate precision prevention of cardiometabolic diseases. Accordingly, we performed unsupervised clustering in four European population-based cohorts (N ≈ 173,000). We detected five discordant p

Based on the DCV-C60 system of fullerene acceptor organic solar cell active materials, the charge transfer process of D-A type molecular materials under the action of an external electric field (Fext) was explored. Within the range of electric field application, the excited state characteristics exhibit certain regular changes. Based on reducing the excitation energy, the excitation mode shows a t

Lead-free metal halide perovskites are emerging as less-toxic alternatives to their lead-based counterparts. However, their applicability in optoelectronic devices is limited, and the charge transport dynamics remain poorly understood. Understanding photo-induced charge and structural dynamics is critical for unlocking the potential of these novel systems. In this work, ultrafast optical and Raman

BACKGROUND: In 2013, it was discovered that a subset of the population in Ronneby, Sweden was exposed to high levels of perfluorinated compounds (PFAS) from drinking water that had been provided by the local Brantafors waterworks and was contaminated by fire-fighting foam from a nearby airport. The start and time-course of population exposures are not known.OBJECTIVE: To investigate the start of P

Sverige är ett av mycket få länder som inte har någon tidsgräns för hur länge häktning får pågå. Dessutom åläggs regelmässigt restriktioner som innebär att den häktade i princip är helt isolerad under häktningstiden. För detta har Sverige fått ta emot långvarig skarp kritik från internationellt håll. Syftet med uppsatsen är att utreda det svenska häktningsinstitutet, med fokus på häktningstidern

Dynamic pricing is a pricing strategy where prices are no longer fixed or constant. Instead, they are continuously readjusted according to perceived demand and factors that influence the desirability of the product. It is in passenger transport where it has one of its biggest applications, in order to increase profits and maximize the use of limited capacity. While extensively studied for its econ

Stockholm har under de senaste åren visat stora hyresökningar på kontorsmarknaden samtidigt som bostadsmarknaden har avsvalnat. Även fast Sverige placeras bra i avseende på flera mått såsom vakans och BNP har städer som också haft bra tillväxt i BNP och låg vakans inte uppvisat lika hög hyrestillväxt. Den här studien undersöker fallet om bostadsmarknaden har påverkat kontorshyrorna i Stockholm. OmIn recent years, Stockholm has shown a large rent increases in the office market simultaneously as the housing market has cooled off. Although Sweden is well measured in several areas such as vacancy and GDP, other cities that also produced significant GDP growth and low vacancy rates have not shown as much rental growth as Stockholm. This study examines if and how the housing market has affected

The aim of this qualitative study has been to analyze how young adults with Yugoslavian background form and sustain relations across national borders. The study covers second-generation migrants (hereby titled as young adults with Yugoslavian background) who are born in Sweden, with Yugoslavian born parents that came to Sweden as refugees between the years of 1990-1998. Ten semi-structured intervi

Straffrätten är ett omfattande rättsområde som ständigt är under utveckling. Det är därför av stor relevans att undersöka och analysera från tid till tid, huruvida rådande principer och presumtioner som tillämpas fortfarande är aktuella i den rådande lagstiftningen, i samband med tillägg och lagändringar. Ett brott som är aktuellt och ett tema för diskussion för myndigheter och regeringen är hedCriminal law is a vast legal area that is constantly under development. For that reason it is important to examine and analyse, from time to time, if the ruling principles and presumptions are up to date with the changes and additions of the law. A crime that is being heavily discussed and is current to our time is honor related crime. Since the year 2020, honor motives are seen as aggravating c

På den ryske botanikern Mikhail Semyonovich Tsvets gravsten står det "Han uppfann kromatografin, separerade molekyler men förenade folk". Hans metod för att separera molekyler används än idag - till exempel i detta arbete. Tsvets försöksuppställning bestod av en glascylinder fylld med kolsyrad kalk, samt en lösning som innehöll olika färgpigment från växter. En stund efter att han hälltAdenosine tetraphosphate, or Ap4A, is a nucleotide with very interesting proposed biological effects. Previous studies have indicated that blood glucose levels in mammals might increase in the presence of Ap4A, and that Ap4A might antagonize pancreatic ATP channels. In order to study these effects further, a reliable method of separating Ap4A from other nucleotides in biological samples is require

Popular science ArRiyadh, the capital city of the Kingdom of Saudi Arabia is one of the fastest growing cities in the world. During the last decade the population of the city has been increased to five million due to heavy migration towards the city. Due to this population pressure, the living conditions in the different neighborhoods of the city are different. The residents in any city are mainly

System co-sensitization and extension of the π-conjugated system are recognized as two key strategies for improving the performance of dye-sensitized solar cells (DSSCs). In this study, density functional theory (DFT) was employed to simulate two experimentally synthesized molecules, RK1 and D205, and to evaluate the performance of their co-sensitization system. Furthermore, molecular design was c

Gold particles are commonly used as catalysts in the vapor-liquid-solid (VLS) growth of GaAs nanowires, but the incorporation of gold into the nanowires can negatively affect their electronic and optical properties. In this work, we investigate the equilibrium concentration of Au in GaAs nanowires using density functional theory calculations combined with thermodynamically assessed chemical potent

Introduction: Oesophageal resection carries significant morbidity and mortality. Artificial intelligence (AI) advances in medical research enable enhanced predictions, flexibility, and interpretability, especially for complex interactions and nonlinear relationships. Material and methods: We used a register-based case-control design nested within prospectively collected data from the Swedish Natio
