Singleshot polychromatic coherent diffractive imaging with a high-order harmonic source

Singleshot polychromatic coherent diffractive imaging is performed with a high-intensity high-order harmonic generation source. The coherence properties are analyzed and several reconstructions show the shot-to-shot fluctuations of the incident beam wavefront. The method is based on a multi-step approach. First, the spectrum is extracted from double-slit diffraction data. The spectrum is used as i

Does passive sound attenuation affect responses to pitch-shifted auditory feedback?

The role of auditory feedback in vocal production has mainly been investigated by altered auditory feedback (AAF) in real time. In response, speakers compensate by shifting their speech output in the opposite direction. Current theory suggests this is caused by a mismatch between expected and observed feedback. A methodological issue is the difficulty to fully isolate the speaker’s hearing so that

Stakeholders, drivers and barriers for local electronics repair: a case study of southern Sweden

Promoting repair of electronics is an important strategy to slow material loops, particularly of critical raw materials, as part of a transition to a circular economy. This contribution accounts for a case study of southern Sweden conducted in order to examine drivers and barriers for repairing electronics, as well as better understand the roles of different stakeholders. Repair activities in the

Effects from usage of pre‑trip information and passenger scheduling strategies on waiting times in public transport: An empirical survey based on a dedicated smartphone application

Väntetider är viktiga indikatorer för graden av restidsoptimering och andra beteendemässiga aspekter bland kollektivtrafikresenärer. Såsom tidigare studier visar så är användningsgraden av avgångsinformation för avresa är en viktig faktor för att realisera potentialen i restidsminskningar genom att möjliggöra för resenärer att optimera sina väntetider. Huvuddelen av den empiriska forskningen hittiWaiting times are important indicators of the degree of travel time optimisation andother behavioural traits among public transport (PT) passengers. As previous studieshave shown, the level and usage of pre-trip information regarding schedule or realtime departures are important factors that infuence the potential to realise traveltime savings by enabling PT passengers to optimise waiting times. M

Physical bounds and radiation modes for MIMO antennas

Modern antenna design for communication systems revolves around two extremes: devices, where only a small region is dedicated to antenna design, and base stations, where design space is not shared with other components. Both imply different restrictions on what performance is realizable. In this paper a computationally efficient method for calculating the fundamental performance bound on spectral

Developmental cost theory predicts thermal environment and vulnerability to global warming

Metazoans must develop from zygotes to feeding organisms. In doing so, developing offspring consume up to 60% of the energy provided by their parent. The cost of development depends on two rates: metabolic rate, which determines the rate that energy is used; and developmental rate, which determines the length of the developmental period. Both development and metabolism are highly temperature-depen

The link between auditory salience and emotion intensity

To ensure that listeners pay attention and do not habituate, emotionally intense vocalizations may be under evolutionary pressure to exploit processing biases in the auditory system by maximising their bottom-up salience. This “salience code” hypothesis was tested using 128 human nonverbal vocalizations representing eight emotions: amusement, anger, disgust, effort, fear, pain, pleasure, and sadne

Modeling train-induced ground-borne vibrations using FEM in a moving frame of reference

To predict ground-borne vibration levels caused by railway traffic, models for estimating the load from the vibration source, as well as the vibration transmission through the ground, are needed. In the present paper, a finite element formulation in a frame of reference following the moving load, is used for modeling a railway slab track. The response of the underlying soil is represented through

Extensive clonal branching shapes the evolutionary history of high-risk pediatric cancers

Darwinian evolution of tumor cells remains underexplored in childhood cancer. We here reconstruct the evolutionary histories of 56 pediatric primary tumors, including 24 neuroblastomas, 24 Wilms tumors and 8 rhabdomyosarcomas. Whole genome copy number and whole exome mutational profiling of multiple regions per tumor was performed followed by clonal deconvolution to reconstruct a phylogenetic tree

Preanalytical Variables for the Genomic Assessment of the Cellular and Acellular Fractions of the Liquid Biopsy in a Cohort of Breast Cancer Patients

Liquid biopsy allows assessment of multiple analytes, providing temporal information with potential for improving understanding of cancer evolution and clinical management of patients. Although liquid biopsies are intensely investigated for prediction and response monitoring, preanalytic variables are of primary concern for clinical implementation, including categories of collection method and sam

Targeted alpha therapy in a systemic mouse model of prostate cancer - a feasibility study

225Ac-PSMA-617 targeted-therapy has demonstrated efficacy in 75-85% of patients; however, responses are not durable. We aimed to establish translatable mouse models of disseminated prostate cancer (PCa) to evaluate effectiveness of 225Ac-PSMA-617 at various disease stages. Methods: C4-2, C4-2B, or 22Rv1 cells were injected into the left ventricle of male NSG mice. Disease progression was monitored

Digitization-based automation and occupational dynamics

We examine the relationship between occupational automation probabilities and employment dynamics over nearly two decades. We show that employment and wage shares of occupations with a higher automation risk have declined in Sweden over the period 1996-2013. This has occurred both at the aggregate private business sector but also within firms, where the wage share changes have been larger than the

The path to a better biomarker: application of a risk management framework for the implementation of PD‐L1 and TILs as immuno‐oncology biomarkers into breast cancer clinical trials and daily practice

Immune checkpoint inhibitor therapies targeting PD‐1/PD‐L1 are now the standard of care in oncology across several hematologic and solid tumor types, including triple negative breast cancer (TNBC). Patients with metastatic or locally advanced TNBC with PD‐L1 expression on immune cells occupying ≥1% of tumor area demonstrated survival benefit with the addition of atezolizumab to nab‐paclitaxel. How

Massively parallel variant characterization identifies NUDT15 alleles associated with thiopurine toxicity

As a prototype of genomics-guided precision medicine, individualized thiopurine dosing based on pharmacogenetics is a highly effective way to mitigate hematopoietic toxicity of this class of drugs. Recently, NUDT15 deficiency was identified as a genetic cause of thiopurine toxicity, and NUDT15-informed preemptive dose reduction was quickly adopted in clinical settings. To exhaustively identify pha

A model for hydride-induced embrittlement in zirconium-based alloys

The critical stress intensity factor for hydrided zirconium-alloys is calculated using a Dugdale type model for a finite crack. The hydride platelets are assumed to surround the ends of the crack. They are located in the process region of the crack tip. The model is used to calculate the temperature dependence of the critical stress intensity factor and the results are compared with measurements p

Upptecknarna och uppteckningarna

Artikeln beskriver två insamlare av folkloristiskt material som var verksamma kring sekelskiftet 1900. Här diskuteras hur det äldre uppteckningsmaterial som finns i arkiven har kommit till och den roll som insamlarna spelade för det som samlades in.

Evaluation of Solid Supports for Slide- and Well-Based Recombinant Antibody Microarrays

Antibody microarrays have emerged as an important tool within proteomics, enabling multiplexed protein expression profiling in both health and disease. The design and performance of antibody microarrays and how they are processed are dependent on several factors, of which the interplay between the antibodies and the solid surfaces plays a central role. In this study, we have taken on the first com

Accuracy and precision of statistical descriptors obtained from multidimensional diffusion signal inversion algorithms

In biological tissues, typical MRI voxels comprise multiple microscopic environments, the local organization of which can be captured by microscopic diffusion tensors. The measured diffusion MRI signal can, therefore, be written as the multidimensional Laplace transform of an intravoxel diffusion tensor distribution (DTD). Tensor-valued diffusion encoding schemes have been designed to probe specif
