We give upper and lower bounds for weighted Chebyshev and residual polynomials on subsets of the real line. As an application, we prove a Szegő-type theorem in the setting of Parreau–Widom sets.

While surface modifications are widely pursued to improve antimicrobial performance of photocatalytic nanoparticles (NPs), the particle–membrane interactions responsible for these effects remain underexplored. We address this gap by investigating the influence of coating TiO2 NPs with the cationic polymer poly(2-(dimethylamino)ethyl methacrylate) methyl chloride quaternary salt (qPDMAEMA). In cont

Background and purpose: Synthetic computed tomography (sCT) enables magnetic resonance imaging (MRI)-only radiotherapy by providing electron density information for dose calculation. While sCT-based planning has been proven sufficiently accurate for convolution-based dose calculation algorithms, linear Boltzmann transport equation (LBTE)-based approaches exhibit higher sensitivity to tissue hetero

To describe the impact of adding a tyrosine kinase inhibitor (TKI) to intensive chemotherapy (IC) on the outcome of de novo BCR::ABL1+ acute myeloid leukemia (AML), we retrospectively analyzed the data of 212 adult AML with ≥20% bone marrow blasts, BCR::ABL1+ or t(9;22)(q34.1;q11.2), no history of previous chronic myeloid leukemia and no prior exposure to BCR-ABL1 TKI. Eighty-nine patients were tr

Blood-based biomarkers are emerging as scalable tools for the diagnosis and monitoring of neurodegenerative diseases, but markers enabling differential diagnosis across major dementias remain limited. Here we show that large-scale plasma proteomics identifies disease-associated signatures across Alzheimer’s disease, dementia with Lewy bodies and frontotemporal dementia. We analyzed 1,318 plasma sa

Ultrasound-induced degradation of soft polymeric colloids, like microgels, as well as a controlled drug release enabled by mechanoresponsive bonds, has recently attracted considerable attention. However, most examples in the literature focus primarily on the applications rather than examining the underlying mechanisms of the structural changes occurring in microgels due to cavitation─changes that

We propose a network behavioral-feedback Susceptible–Infected–Recovered (SIR) epidemic model in which the interaction matrix describing the infection rates across subpopulations depends in feedback on the current epidemic state. This model captures both heterogeneities in individuals’ mixing, contact frequency, aptitude to contract and spread the infection, and endogenous behavioral responses such

Background: Iron deficiency is a common and clinically relevant comorbidity in heart failure, associated with reduced functional capacity, higher symptom burden, and increased hospitalisation risk. Most evidence on iron deficiency in heart failure originates from hospital-based cohorts, whereas the epidemiology and clinical implications in primary care populations remain poorly described. This stu

BACKGROUND AND PURPOSE: The glymphatic system facilitates perivascular clearance, and its dysfunction has been implicated in neurodegenerative diseases. Diffusion tensor imaging along the perivascular space (DTI-ALPS) has been proposed as an indirect approach to assess glymphatic function, but its reliability is debated. The choice of b-value is an aspect of possible improvement. While a b-value o

Introduction: The structures of the skull and the brain are related to each other. Prior work in individuals with isolated congenital anosmia (ICA) showed that these individuals were characterized by olfactory bulb (OB) defects. The aim of this study was to compare the morphological pattern of the anterior skull base surrounding the OB between individuals with ICA and normosmic controls. We meant

Time-resolved X-ray solution scattering (TR-XSS) provides direct access to protein structural dynamics but has largely been restricted from the microsecond range up to approximately 100 milliseconds. As a result, slower enzymatic systems, including many P-type ATPases, remain difficult to probe. Here, we extend the temporal reach of TR-XSS by sequentially positioning radiation damage-free acquisit

This thesis presents the aerodynamic design and optimization of a three-stage low-pressure axial turbine for the RM400 turbofan engine, developed as part of the VILD project in collaboration between GKN Aerospace, Chalmers, KTH, and Lund University. The primary objective was to redesign the turbine, previously implemented with a cooled first-stage blade, into an uncooled-blade configuration capabl

The increasing number of processing elements, memories, and accelerators in modern systems-on-chip places growing demands on on-chip communication. This thesis presents ToPoNoC, a topology-parametric Network-on-Chip implemented in Chisel with Mesh, Ring, and hybrid Mesh–Ring configurations. The design combines packet/flit transport, virtual-channel buffering, deterministic routing, packet-level ar

This Master’s thesis explores the reconstruction of photoelectron angular distributions using spherical harmonic decomposition with a view of characterize the polarization state of the ionizing light field. Photoelectron angular distributions describe the measured angular distribution of emitted electrons, which follows from the probability of detecting an electron at different angles. These distr

The Baltic Sea is heavily affected by anthropogenic pressures, causing toxic and dangerous living conditions for marine species and destroying ecosystems. Many of the problems stem from overfishing, nutrient runoffs causing eutrophication and a very low water exchange outer seas, making the water in the Baltic Sea brackish. When the passenger ship Marco Polo ran aground outside Hanöbukten 2023, i

Students in Serbia have been protesting and blockading since the lethal accident at Novi Sad train station on 1 November 2024. For the last year and a half, they have persistently asked the state institutions to act in accordance with the law. They refuse to be appeased by the president or scared to submission by forceful interventions by the police. Instead, they invoke their human rights to
