Panel bootstrap tests of slope homogeneity

This paper proposes two bootstrap-based tests that can be used to infer whether the individual slopes in a panel regression model are homogenous. The first test is suitable when wanting to infer the null of homogeneity versus the general alternative, while the second is suitable when wanting to infer the units of the panel that can be pooled. Both approaches are shown to be asymptotically valid, a

Global socio-technical regimes

This paper addresses the question why socio-technical transitions followsimilar trajectories in various parts of the world, even though the relevant material preconditions and institutional contexts vary greatly between different countries. It takes a critical stance on the implicit methodological nationalism in transition studies’ socio-technical regime concept and proposes an alternative ‘global

Law and Digital Society

The article argues that the digitally mediated and data-driven development stresses the need for socio-legal scrutiny. It focuses and briefly outline socio-legally relevant aspects of the “sharing” economy, that poses a number of conceptual issues on how we understand and regulate innovative platform based ventures.

We focus and briefly outline socio-legally relevant aspects of the “sharing” economy, that poses a number of conceptual issues on how we understand and regulate innovative platform based ventures. This also arguably underscores a number of issues relating to the role of consumer and

Clock-gating of streaming applications for energy efficient implementations on FPGAs

The paper investigates the reduction of dynamic power for streaming applications yielded by asynchronous dataflow designs by using clock gating techniques. Streaming applications constitute a very broad class of computing algorithms in areas such as signal processing, digital media coding, cryptography, video analytics, network routing and packet processing and many others. The paper introduces a

Paradiset. Ökenfädernas tänkespråk. Den systematiska samlingen VIII : Om att inte göra något för syns skull

Boken innehåller en grekisk text (baserad på cod. Athos Protaton 86) utgiven av Britt Dahlman och en svensk översättning av den systematiska samlingen av Apophthegmata Patrum (Ökenfädernas tänkespråk), bok 8. Översättningen har gjorts gemensamt av deltagarna i översättningsseminariet vid Johannesakademin.The book contains a Greek text (based on MS Athos Protaton 86) edited by Britt Dahlman and a Swedish translation of the Systematical collection of the Apophthegmata Patrum, book 8. The translation was made jointly by the participants in the translation seminar at Johannesakademin.

Outset of the Morphology of Nanostructured Silica Particles during Nucleation Followed by Ultrasmall-Angle X-ray Scattering

Nucleation and growth of SBA-15 silica nanostructured particles with well-defined morphologies has been followed with time by small-angle X-ray scattering (SAXS) and ultrasmall-angle X-ray scattering (USAXS), using synchrotron radiation. Three different morphologies have been compared: platelets, toroids, and rods. SEM observations of the particles confirm that two key physical parameters control

A structure of CdS/CuxS quantum dots sensitized solar cells

This work introduces a type of CdS/CuxS quantum dots (QDs) as sensitizers in quantum dot sensitized solar cells by in-situ cationic exchange reaction method where CdS photoanode is directly immersed in CuCl2 methanol solution to replace Cd2+ by Cu2+. The p-type CuxS layer on the surface of the CdS QDs can be considered as hole transport material, which not only enhances the light harvesting of pho

IL1RAP antibodies block IL-1-induced expansion of candidate CML stem cells and mediate cell killing in xenograft models

Chronic myeloid leukemia (CML) is currently treated with tyrosine kinase inhibitors, but these do not effectively eliminate the CML stem cells. As a consequence, CML stem cells persist and cause relapse in most patients upon drug discontinuation. Furthermore, no effective therapy exists for the advanced stages of the disease. Interleukin-1 receptor accessory protein (IL1RAP; IL1R3) is a coreceptor

Absent ileocecal valve predicts the need for repeated step in children

Background: Serial transverse enteroplasty facilitates weaning from parenteral support in selected patients with short bowel syndrome, although repeated procedure is frequently required. Our aim was to evaluate the outcome of a series of patients after serial transverse enteroplasty and define predictors of repeated serial transverse enteroplasty and weaning off parenteral support. Methods: All ch

Understanding drought dynamics during dry season in Eastern Northeast Brazil

Eastern Northeast Brazil (ENEB) generally experiences a high variability in precipitation in the dry season, with amplitudes that can overcome 500mm. The understanding of this variability can help in mitigating the socio-economic issues related to the planning and management of water resources this region, which is highly vulnerable to drought. This work aims to assess spatio-temporal variability

Single-Port Laparoscopy-Assisted Appendectomy in Children : A Method Described

Single-incision laparoscopic appendectomy (SILA) has gained popularity in children, and several different techniques have been described, including intracorporeal and extracorporeal techniques and single-channel and multi-channel single-port techniques. However, there has been a concern that exteriorizing an infected appendix through the umbilical channel would increase the risk of postoperative w

Affinity-bead-mediated enrichment of CD8+ lymphocytes from peripheral blood progenitor cell products using acoustophoresis

Acoustophoresis is a technique that applies ultrasonic standing wave forces in a microchannel to sort cells depending on their physical properties in relation to the surrounding media. Cell handling and separation for research and clinical applications aims to efficiently separate specific cell populations. Here, we investigated the sorting of CD8 lymphocytes from peripheral blood progenitor cell

The status and challenge of global fire modelling

Biomass burning impacts vegetation dynamics, biogeochemical cycling, atmospheric chemistry, and climate, with sometimes deleterious socio-economic impacts. Under future climate projections it is often expected that the risk of wildfires will increase. Our ability to predict the magnitude and geographic pattern of future fire impacts rests on our ability to model fire regimes, using either well-fou
