Side-gated, enhancement mode, InAs nanowire double quantum dot devices-toward controlling transverse electric fields in spin-transport measurements

A double quantum dot system with a definitive transverse electric field in the plane of the sample is defined by combining a facile side-gating technique with enhancement mode InAs nanowires. Positive bias on the plunger gates enhance quantum dot segments along the nanowire, negative bias on barrier gates deplete regions, and situating gates biased at opposite polarities on opposing sides of the n

Effects of adjuvant tamoxifen over three decades on breast cancer–free and distant recurrence–free interval among premenopausal women with oestrogen receptor–positive breast cancer randomised in the Swedish SBII:2pre trial

Aims: The primary aim was to compare 2 years of adjuvant tamoxifen versus no systemic treatment in premenopausal patients with oestrogen receptor (ER)–positive tumours, regarding breast cancer–free interval (BCFi) and distant recurrence–free interval (D-RFi), with 30 years of follow-up and for specified intervals. Moreover, we aimed to investigate the effects of adjuvant tamoxifen on the incidence

Analysis of Sharing Economy Services : Initial Findings from Sharing Cities Sweden

In this paper, we analyze different types of sharing economy services. The sharing economy is a wide concept where many types of activities and services can be included. Overall we aim to identify recurrent patterns but also similarities and differences between different types of sharing services. We discuss a multitude of different services, e.g. car pools, bike pools, sharing of tools and equipm

Millimeter Wave Imaging and Phased Array Antennas for 5G and Aerospace Applications

Phased array antennas are cornerstones in many proposed antenna solutions concerning the next generation of both airborne radar systems and wireless communication systems (5G). Additionally, millimeter wave (mm-wave) frequencies are expected to play an integral role in 5G, and are deemed well-suited for inspecting structural components used in the aerospace industry.This dissertation consists of a

Experimental and numerical investigations of cross-laminated timber elements at in-plane beam loading conditions

Cross laminated timber (CLT) at in-plane beam loading conditions presents a complex stress state wherefore several failure modes and geometry parameters need to be considered in design. The work presented here includes experimental investigations of CLT beams for comparison and validation of an analytical model and design proposals previously suggested by the authors. All relevant failure modes ar

Challenges in transdisciplinary research : Example from a study on people as part of energy and ventilation systems in residential buildings (PEIRE)

Energy efficiency measures in residential buildings typically include changes in ventilation and heating systems, and increased thermal insulation of the building envelope. The expected energy efficiency is not always reached, despite large knowledge and professional implementation of each separate measure. Thereis a lack in understanding of how technical systems interact, and how the ocupants are

The functional impact of G protein-coupled receptor 142 (Gpr142) on pancreatic β-cell in rodent

We have recently shown that the G protein-coupled receptor 142 (GPR142) is expressed in both rodent and human pancreatic β-cells. Herein, we investigated the cellular distribution of GPR142 within islets and the effects of selective agonists of GPR142 on glucose-stimulated insulin secretion (GSIS) in the mouse islets and INS-1832/13 cells. Double-immunostaining revealed that GPR142 immunoreactivi

Jag trodde aldrig att Sverige skulle låta detta ske

Det är många som har anledning att i dag be många svenska skolelever i det muslimska skolsystemet om ursäkt för att de inte har fått samma demokratiska och allsidiga skolgång som andra svenska elever.

Muslimska brödraskapet talar med kluven tunga

Sverige är ett av de mest statistiskt utvecklade länderna när det gäller tillit mellan människor och samhällets organ samt människor sinsemellan. En utmaning när ett sådant samhälle möter samhällen som färgas av pre-modernitet är användning av källkritik. Det måste vi bli bättre på när en politisk rörelse klär sig i en religiös dräkt med vita lögner som metod.

Labour market regulations, changes in working life and the importance of apprenticeship training : A long-term and comparative view on youth transition from school to work

What is the significance of regulations of job contracts and wages when it comes to young people’s access to labour market? This is an issue that has attracted and continues to attract a great deal of interest in both research and politics. Proposals for deregulated employment protection and reduced entry-level pay recur regularly in public debate. In our view it is incomprehensiblehow sectors of What is the significance of regulations of job contracts and wages when it comes to young people’s access to labour market?

Implicit associations between individual properties of color and sound

We report a series of 22 experiments in which the implicit associations test (IAT) was used to investigate cross-modal correspondences between visual (luminance, hue [R-G, B-Y], saturation) and acoustic (loudness, pitch, formants [F1, F2], spectral centroid, trill) dimensions. Colors were sampled from the perceptually accurate CIE-Lab space, and the complex, vowel-like sounds were created with a f

Högtidsdag i Svenska Akademien : dåtida och samtida föreställningar om studenters skrivande

Studenters skrivande hamnar då och då i fokus för allmänhetens uppmärksamhet, inte minst genom berättelser i medierna. Att det skett en försämring och att studenterna aldrig skrivit lika illa som nu tas för givet. Det antas innebära att högskolans lärare inte kan syssla med det de ska. Men om man skrapar på ytan märker man att de här föreställningarna funnits länge. I denna text redogör jag för et

A Constraining Hyperplane Technique for State Variable Constrained Optimal Control Techniques

A new approach to the numerical solution of optimal control problems with state-variable inequality constraints is presented. It is shown that the concept of constraining hyperplanes may be used to approximate the original problem with a problem where the constraints are of a mixed state-control variable type. The efficiency and the accuracy of the combination of constraining hyperplanes and a sec

Lactobacillus reuteri NAD(P)H oxidase : Properties and coexpression with propanediol-utilization enzymes for enhancing 3-hydroxypropionic acid production from 3-hydroxypropionaldehyde

Lactobacillus reuteri metabolizes glycerol through propanediol-utilization (Pdu) pathway to 1,3-propanediol (1,3-PD) via 3-hydroxypropionaldehyde (3-HPA) as intermediate. In the resting cells, the oxidized co-factor obtained in the reaction is regenerated by simultaneous oxidation of 3-HPA to 3-hydroxypropionic acid (3-HP) using propionaldehyde dehydrogenase (PduP), phosphotransacylase (PduL) and
