Utan effektiva, energisnåla och specialanpassade chip riskerar både digitaliseringen och de energibesparingar som krävs för en grön omställning att undergrävas eller utebli. Sverige måste engagera sig i samarbeten om halvledarteknologi, skriver Erik Renström och Heiner Linke.
Background: Neuroma formation occurs after inappropriately or untreated nerve injuries. Patients surgically treated for neuroma were characterized and factors influencing outcome evaluated. Methods: In a retrospective observational study, data from medical records of patients surgically treated for neuroma in two Swedish regions were analyzed. Results: In 115 included patients (median age at surge
History is written by the powerful. Representations of the past are framed within the structures of the dominant institutions today, and other pasts – those of the enslaved, the marginalised, the disenfranchised – are often suppressed. Drawing of Eric Wolf’s Europe and the People Without History, this chapter explores how the fertile lands of the Cauca Valley, Colombia, have been transformed into
PURPOSE: To analyze the incidence and risk factors for posterior capsule rupture (PCR) in cataract surgery. SETTING: European clinics affiliated with the European Registry of Quality Outcomes for Cataract and Refractive Surgery (EUREQUO). DESIGN: Retrospective cross-sectional register-based study. METHODS: Data were obtained from the EUREQUO. The database contains data on demographics, comorbiditi
INTRODUCTION: The prophylactic regimen in children with severe haemophilia is suggested in various publications and guidelines. Few data exist on its implementation in clinical practice.AIM: To investigate the implementation of primary prophylaxis based on real-life data from PedNet during the last 20 years.METHODS: All children from the PedNet cohort (n = 1260) with severe haemophilia A (SHA) or
Superficial CD34-positive fibroblastic tumor (SCD34FT) is a rare soft tissue neoplasm that shows overlapping features with PRDM10-rearranged soft tissue tumor (PRDM10-STT). This study characterizes the clinicopathologic, immunohistochemical, and molecular features of SCD34FT in a series of 59 cases. Fluorescence in situ hybridization to assess for PRDM10 rearrangement was performed in 12 tumors. I
Changing societal challenges and priorities call for new ways of managing agricultural land and for new forms of land ownership. The Danish pilot programme for multifunctional land consolidation (MUFJO) is seen as a frontrunner for a larger land reform. The programme ensures collective planning and long-term solutions, but cannot alone ensure the goals for re-wetting agricultural lands as stipulat
Introduction: Monoaminergic activity modulates nociceptive transmission in the central nervous system (CNS). Although pain is the most disabling symptom of osteoarthritis (OA), limited knowledge exists regarding the CNS mechanisms that amplify pain and drive sensitization processes in humans.Objectives:The main objective of this study was to evaluate associations between cerebrospinal fluid (CSF)
Purpose of ReviewBreathlessness is a common, distressing, and limiting symptom that many people avoid by reducing their activity. This review discusses exertional tests that can be used for uncovering and assessing breathlessness depending on the person's severity of illness, function, the setting, and aim of the assessment.Recent FindingsStandardized exertional tests are useful to uncover 'hidden
BACKGROUND: KRAS mutation can alter the treatment plan after resection of colorectal cancer. Despite its importance, the KRAS status of several patients remains unchecked because of the high cost and limited resources. This study developed a deep neural network (DNN) to predict the KRAS genotype using hematoxylin and eosin (H&E)-stained histopathological images. STUDY DESIGN: Three DNNs were c
Many species up- or downregulate their resting metabolic rate (RMR) when they encounter favourable or unfavourable feeding conditions, respectively. This is thought to promote faster growth when food is abundant and conserve energy reserves when food is scarce. The time it takes to express metabolic plasticity remain little studied. Here, we develop a conceptual model showing how rapid or slow met
The evolution of the diamond (111) surface as it undergoes reconstruction and subsequent graphene formation is investigated with angle-resolved photoemission spectroscopy, low energy electron diffraction, and complementary density functional theory calculations. The process is examined starting at the C(111)-(2×1) surface reconstruction that occurs following detachment of the surface adatoms at 92
We investigate Majorana modes in a quantum spin chain with bond-dependent exchange interactions by studying its dynamics. Specifically, we consider two-time correlations for the anisotropic Kitaev-Heisenberg (KH) Hamiltonian close to the so-called Kitaev critical point. Here the model coincides with a phase boundary of two uncoupled instances of Kitaev's model for p-wave superconductors, together
The Josephson junction of a strong spin-orbit material under a magnetic field is a promising Majorana fermion candidate. Supercurrent enhancement by a magnetic field has been observed in the InAs nanowire Josephson junctions and assigned to a topological transition. In this work we observe a similar phenomenon but discuss the nontopological origin by considering the trapping of quasiparticles by v
We measure the rates and coupling coefficients for local Andreev, nonlocal Andreev, and elastic cotunneling processes. The nonlocal Andreev process, giving rise to Cooper pair splitting, exhibits the same coupling coefficient as the elastic cotunneling whereas the local Andreev process is more than 2 orders of magnitude stronger than the corresponding nonlocal one. Theory estimates describe the fi
Quantum annealing is a promising approach for obtaining good approximate solutions to difficult optimization problems. Folding a protein sequence into its minimum-energy structure represents such a problem. For testing new algorithms and technologies for this task, the minimal lattice-based [hydrophobic (H) or polar (P) beads] HP model is well suited, as it represents a considerable challenge desp
Here, we demonstrate an experimental proof of concept for nanofocused x-ray photon correlation spectroscopy, a technique sensitive to nanoscale fluctuations present in a broad range of systems. The experiment, performed at the NanoMAX beamline at MAX IV, uses a novel event-based x-ray detector to capture nanoparticle structural dynamics with microsecond resolution. By varying the nanobeam size fro
