During the last two decades, applications of nonlinear dynamic and chaos theories to hydrologic systems and processes have been on the rise. Early applications of these theories focused mainly on the investigation and prediction of chaos in rainfall and river flow dynamics. Subsequent years witnessed their applications for other purposes (e.g. data disaggregation, missing data estimation, reconstr
Importance: Disulfiram has demonstrated broad antitumoral effect in several preclinical studies. One of the proposed indications is for the treatment of glioblastoma. Objective: To evaluate the efficacy and safety of disulfiram and copper as add-on to alkylating chemotherapy in patients with recurrent glioblastoma. Design, Setting, and Participants: This was a multicenter, open-label, randomized p
The goal of person text-image matching is to retrieve images of specific pedestrians using natural language. Although a lot of research results have been achieved in persona text-image matching, existing methods still face two challenges. First,due to the ambiguous semantic information in the features, aligning the textual features with their corresponding image features is always tricky. Second,
Clinical evidence accumulated from hemophilic patients during prophylaxis with recombinant activated factor VII (rFVIIa) suggests that the duration of the hemostatic action of rFVIIa exceeds its predicted plasma half-life. Mechanisms involved in this outcome have not been elucidated. We have investigated in vitro the redistribution of rFVIIa in platelets from healthy donors, patients with FVII def
Introduction: Risk evaluation for preeclampsia in early pregnancy allows identification of women at high risk. Prediction models for preeclampsia often include circulating concentrations of placental growth factor (PlGF); however, the models are usually limited to a specific PlGF method of analysis. The aim of this study was to compare three different PlGF methods of analysis in a Swedish cohort t
Internationalization has become one of the main strategic goals of universities as part of their endeavors to prepare students for careers in a globalized world. However, the establishment of English-medium instruction (EMI) has raised concerns about the quality of teaching and learning, given that most stakeholders involved in the process are second language (L2) speakers of English. Therefore, a
Introduction: Educational attainment, widely used in epidemiologic studies as a surrogate for socioeconomic status, is a predictor of cardiovascular health outcomes. Methods: A two-stage genome-wide meta-analysis of low-density lipoprotein cholesterol (LDL), high-density lipoprotein cholesterol (HDL), and triglyceride (TG) levels was performed while accounting for gene-educational attainment inter
Group A streptococci have evolved multiple strategies to evade human antibodies, making it challenging to create effective vaccines or antibody treatments. Here, we have generated antibodies derived from the memory B cells of an individual who had successfully cleared a group A streptococcal infection. The antibodies bind with high affinity in the central region of the surface-bound M protein. Suc
In this study, a narrative-based language intervention (NBLI) is evaluated in children with HL based on selected narrative outcome measures important for telling and retelling stories. Nine Danish children with slight to severe sensorineural HL in the age range of 4;11–8;8 years participated. The study had a single-arm early efficacy design. The NBLI consisted of four parts: (1) warm-up activity,
Background: Measuring multiple and higher-order interaction effects between multiple categorical variables proves challenging. Objectives: To illustrate a multilevel modelling approach to studying complex interactions. Methods: We apply a two-level random-intercept linear regression to a binary outcome for individuals (level-1) nested within strata (level-2) defined by all observed combinations of
In Sweden, penetrating injuries to the lung and especially to the heart are fortunately rare. We hereby present a case-report on a young man who was stabbed in the right lung and heart. The paramedics arrived at the scene one minute after the alarm and instituted mechanical ventilation and fluid infusion. Ten minutes later the young man arrived at the emergency department. By then the patient was
Autonomous vehicles (AVs) have been the subject of extensive research in recent years and are expected to completely transform the operation of transport networks and revolutionize the automotive industry in the coming decades. Modeling detailed interactions among vehicles with varying levels of penetration rates is essential for evaluating the potential effects. One such investigation is being pe
Universities worldwide have increased their competition for the best students and employees. Consequently, business schools are pressured to demonstrate excellence and differentiate themselves through brand building. One essential part of branding is the quality narratives that universities present to the public. We study the presentation of quality in Nordic business schools. Data concerning the
Correlated electron physics is intrinsically a multiscale problem, since high-energy electronic states screen the interactions between the correlated electrons close to the Fermi level, thereby reducing the magnitude of the interaction strength and dramatically shortening its range. Thus the handling of screening is an essential ingredient in the first-principles modeling of correlated electron sy
The Aβ42 peptide (APP(672–713)), associated with Alzheimer disease, is highly prone to form amyloid fibrils and has been extensively studied through in vitro experiments. Such experiments represent a basis for understanding the biophysical chemistry of amyloid-related diseases. In this communication, we show that homogeneous primary nucleation in vitro of Aβ42 fibrils is a very rare event, implyin
Chirality is omnipresent in the living world. As biomimetic nanotechnology and self-assembly advance, they too need chirality. Accordingly, there is a pressing need to develop general methods to characterize chiral building blocks at the nanoscale in liquids such as water─the medium of life. Here, we demonstrate the chiroptical second-harmonic Tyndall scattering effect. The effect was observed in
