A clear understanding of the mechanisms governing the growth of nanowires is crucial to achieving control over their structures and properties. Here, we employ molecular dynamics (MD) simulations to investigate several important phenomena in Au-catalyzed Si nanowires (SiNWs) grown via the vapor–liquid–solid method. MD simulation serves as a complementary tool for uncovering the mechanisms of nanow

Objective People with advanced chronic obstructive pulmonary disease (COPD) have substantial palliative care needs, but uncertainty exists around appropriate identification of patients for palliative care referral. We conducted a Delphi study of international experts to identify consensus referral criteria for specialist outpatient palliative care for people with COPD. Methods Clinicians in the fi

Shadi Hamid proposes “democratic minimalism” as a system and means of governing and rotating power with no prejudice to substantive ideological outcomes. Democratic minimalism is meant to decouple the question of actualizing an ideal society, even a liberal one that provides maximum freedom for the maximum groups of people, from the mechanism of transferring power between groups with opposing beli

The crucial role of aerobic energy production in sustaining eukaryotic life positions mitochondrial processes as key determinants of an animal's ability to withstand unpredictable environments. The advent of new techniques facilitating the measurement of mitochondrial function offers an increasingly promising tool for conservation approaches. Herein, we synthesize the current knowledge on the link

The central complex (CX), a remarkable brain region at the core of insect behaviors, has been the subject of extensive research for decades. In this review, we offer a comprehensive historical perspective on the anatomy, development, and function of the CX. The CX consists of discrete and highly structured neuropils found at the center of the brain, which are conserved across insects and arthropod

We have previously proposed and evaluated acoustophoresis for the enrichment of circulating tumor cells (CTC) and clusters thereof from the blood of patients with prostate cancer [1]. In that protocol, the cells were fixed and preserved in paraformaldehyde before processing and were thus non-viable. To enable future enrichment of also viable CTCs from patients, we have in this study investigated t

We recently introduced the concept of thermoacoustic streaming in microchannels wherein a thermal field is generated inside an acoustic cavity. The result is a fast and controllable streaming for which the thermal energy is provided either by an LED light source [1], or a laser [2]. While in previous works we have measured this effect at steady state, we now present measurements of the build-up an

Diverse forest landscapes contribute to reaching various forest policy goals. Understanding how the diversity of forests in a landscape is distributed among forest properties and how it is related to biogeographical and ownership factors can be helpful for effective policy implementation. We created a forest characteristics-based typology of non-industrial private forest properties aiming to captu

Objective: Speed-securing measures are intended to, as the name suggests, to secure that the speeds of road users do not exceed the safe speed for a given type of environment. The purpose of this study was to make an evaluation of existing speed-securing measures on rural roads in Sweden to see how well they manage to limit the speed. Methods and data: A total of 34 unique locations have been film

By combining acoustic fields and liquid flows in microchannels we develop tools to chart and separatebiological particles based on their bio-mechanical properties. I will present an overview of three ongoingprojects where acoustic forces are utilized to separate blood cells.We studied the packing behavior of whole blood in a sound field. We discovered that cells self-organizesuch that red blood cells

Aim: We evaluated the increased centralisation of extremely preterm (EPT) births in Sweden in relation to the changes in mortality and morbidity. Methods: Population-based data covering Swedish live births from 22 + 0 to 26 + 6 weeks of gestation during 2004–2007 and 2014–2016 were analysed for associations between time-period, birth within (inborn) or outside (outborn) regional centres, and outco

Atomic layer deposition (ALD) has been an attractive tool in the fabrication of Pt thin layers and nanoparticles. In this work, the surface chemistry of Pt ALD through the MeCpPtMe3/N2-plasma (N2*) and the MeCpPtMe3/NH3-plasma (NH3*) processes at 300 °C have been investigated in detail using in vacuo X-ray photoelectron spectroscopy (XPS) during the ALD process, so that the evolution of surface sp

The initial adsorption of MeCpPtMe 3 is investigated using synchrotron-based ambient pressure x-ray photoelectron spectroscopy (XPS). The experiments are done on a native oxide-covered Si substrate. In addition, a reaction with O 2 and the created Pt surface was investigated. Inspiration for the reaction studies was found from atomic layer deposition of metallic Pt, process that uses the same comp

Today, atomic layer deposition (ALD) has become a firm corner stone of thin film deposition technology. The microelectronics industry, an early adopter of ALD, imposes stringent requirements on ALD to produce films with highly defined physical and chemical properties, which becomes even more important as device and component dimensions decrease. This, in turn, means that our understanding of the c

Background: The Duke criteria for diagnosing infective endocarditis (IE) were recently updated by the International Society for Cardiovascular Infectious Diseases (ISCVID) with the purpose of enhancing diagnostic specificity and sensitivity. This study investigated the performance of the Duke-ISCVID criteria in relation to previous criteria. Method: This retrospective single centre cohort study in

Background: Despite many atrial fibrillation (AF) patients being at risk of bleeding, very limited data are available on bleeding rates of different direct oral anticoagulants based on the spectrum of bleeding risk. Objective: We aimed to compare the risk of major bleeding and thromboembolic events with apixaban vs rivaroxaban for AF patients stratified by bleeding risk. Methods: We conducted a po
