Direct and precise manipulation of sub-micron particles such as bacteria, platelets, organelles, microvesicles, exosomes or virus particles is challenging. We describe for the first time how acoustic streaming in the bulk can be efficiently reduced by introducing a density or compressibility gradient and that this enables focusing of 500-nm-diameter particles in a standard acoustophoresis channel.

Ever since Goldin-Meadow, S., C. Mylander, W. C. So, and A. Özyürek. 2008. The natural order of events: How speakers of different languages represent events nonverbally. PNAS 105: 9163–9168. proposed that there is a preferred order in sequential non-verbal event representations (Actor > Patient > Act), apparently independent of the default word order in one’s native language, the topic has been th

The workshop brings together differing perspectives on what makes research data possible. How data is made represents an on-going negotiation between a number of elements. It reflects, firstly, the nature of disciplines and thecomplex way this is linked to cultures of research data and data sharing. Secondly, data is made across the complex temporalities within different practices of its managemen

Preclinical studies suggest that stem cell therapy (SCT) may improve poststroke recovery, and clinical trials investigating safety are ongoing. However, knowledge about patients' attitudes to SCT in stroke is limited. We evaluated the knowledge and attitudes to this therapeutic approach as well as possible factors influencing this among stroke patients potentially suitable for SCT. Consecutive fir

This paper deals with those provisions of the new EU Regulation No. 2015/848 on Insolvency Proceedings (Recast) that create a system of national insolvency registers and establish a decentralized system for the interconnection of such registers by means of the European e-Justice Portal.

In the recently published Swedish Security Service Yearbook 2020, which discusses the main security and intelligence challenges faced by Sweden over the past year, Iran is mentioned 14 times. The Islamic Republic, together with Russia and China, is a direct threat to Swedish national security.

OBJECTIVE: To evaluate the effect of platelet:erythrocyte (P:E) ratios on Plasmodium falciparum erythrocyte invasion.BACKGROUND: Recent reports have shown that platelets are directly involved in the immune response towards P. falciparum during erythrocyte invasion. However, the literature both supports and conflicts with a role for platelets in limiting invasion. Also, the effect of platelet numbe

Chronic obstructive pulmonary disease (COPD) is characterized by airway inflammation, small airway remodeling, and emphysema. Airway remodeling in patients with COPD involves both the airway epithelium and the subepithelial extracellular matrix (ECM). However, it is currently unknown how epithelial remodeling in COPD airways depends on the relative influence from inherent defects in the epithelial

Background: To date, there is neither any pharmacological treatment with efficacy in traumatic brain injury (TBI) nor any method to halt the disease progress. This is due to an incomplete understanding of the vast complexity of the biological cascades and failure to appreciate the diversity of secondary injury mechanisms in TBI. In recent years, techniques for high-throughput characterization and

The use of radio signal for position tracking (positioning) and navigation has a long tradition. Most notably, global navigation satellite systems (GNSS) are now widely applied for civilian applications, ranging all the way from tracking of cargo containers to gaming. However, GNSS suffers from limited coverage in dense urban areas and indoors and also from a limited position accuracy, which rules

This paper provides an empirical analysis of the effectiveness of real-time feedback technology in the Swedish residential sector. We take the ‘100Koll’ service provided by one the largest energy companies in Sweden as a case study. Based on an intervention group (i.e. people using the service) of 1 753 households, a survey was carried out to explore behavioural, moral, socio-economic and contextu

Effective separation methods for fractionating blood components are needed for numerous diagnostic and research applications. This paper presents the use of acoustophoresis, an ultrasound based microfluidic separation technology, for label-free, gentle and continuous separation of mononuclear cells (MNCs) from diluted whole blood. Red blood cells (RBCs) and MNCs behave similar in an acoustic stand

High-ductility ductile iron was alloyed with 0-1.8wt% Ni in this paper. The low-temperature impact toughness test and corrosion test of simulated seawater static whole-soaking were conducted to research the effect of nickel on the low-temperature impact toughness and corrosion resistance of high-ductility ductile iron. The results show that with nickel increasing, the impact toughness under low te

Post-cardiac arrest brain injury (PCABI) is caused by initial ischaemia and subsequent reperfusion of the brain following resuscitation. In those who are admitted to intensive care unit after cardiac arrest, PCABI manifests as coma, and is the main cause of mortality and long-term disability. This review describes the mechanisms of PCABI, its treatment options, its outcomes, and the suggested stra

Landscapes play an important role in many areas of biology, in which biological lives are deeply entangled. Here we discuss a form of landscape in evolutionary biology which takes into account (1) initial growth rates, (2) mutation rates, (3) resource consumption by organisms, and (4) cyclic changes in the resources with time. The long-term equilibrium number of surviving organisms as a function o
