RadioWeaves for efficient connectivity : Analysis and impact of constraints in actual deployments

We present a new type of wireless access infrastructure consisting of a fabric of dispersed electronic circuits and antennas that collectively function as a massive, distributed antenna array. We have chosen to name this new wireless infrastructure 'RadioWeaves' and anticipate they can be integrated into indoor and outdoor walls, furniture, and other objects, rendering them a natural part of the e

The use of ICD codes to identify IBD subtypes and phenotypes of the Montreal classification in the Swedish National Patient Register

Introduction: Whether data on International Classification of Diseases (ICD)-codes from the Swedish National Patient Register (NPR) correctly correspond to subtypes of inflammatory bowel disease (IBD) and phenotypes of the Montreal classification scheme among patients with prevalent disease is unknown.Materials and methods: We obtained information on IBD subtypes and phenotypes from the medical re

Machinability evaluation of low-lead brass alloys

The machinability of brass is considered to increase with the addition of lead as an alloying element. Due to both environmental and health reasons, the decrease of lead in brass components is of high importance. Several mechanical and thermal material properties control a materials machinability, in combination with the chosen machining system. To evaluate the difference in machinability between

There is logic in logit - Including wear rate in Colding's tool wear model

Modelling of tool wear in metal cutting processes has been the foundation of the field since the famous Taylor's tool life model. Tool wear models have been developed for planning machining operations and calculating production costs. Most wear models do not include wear rate in the model but rather just the final wear at end of tool life, i.e. the limiting wear. This is a major disadvantage of Ta

KID Project : an internet-based digital video atlas of capsule endoscopy for research purposes

BACKGROUND AND AIMS: Capsule endoscopy (CE) has revolutionized small-bowel (SB) investigation. Computational methods can enhance diagnostic yield (DY); however, incorporating machine learning algorithms (MLAs) into CE reading is difficult as large amounts of image annotations are required for training. Current databases lack graphic annotations of pathologies and cannot be used. A novel database,

Effect of wood density and cracks on the moisture content of coated Norway spruce (Picea abies (L.) Karst.)

A protective coating is often used on the cladding of wooden facades to limit the absorption of moisture. Low wood moisture content (MC) is essential to obtain satisfactory durability performance. Wood density is known to influence the water sorption and crack formation of uncoated wood. However, the effect of density on the aforementioned behaviors of coated spruce is not yet fully understood. Si

Pacemaker programming in patients with first-degree AV-block : Programming pattern and possible consequences

Background: The optimal way of pacing in patients with an indication for pacing and concomitant first-degree atrioventricular (AV)–block is not known, and consequently, firm guidelines on this topic are lacking. This study explored the current pacemaker programming pattern in patients with first-degree AV-block who have a dual chamber pacemaker without cardiac resynchronization. Methods: The study

Ledaren i det svenska civila samhället - En enkätstudie

Rapporten handlar om civilsamhällets ledare och bygger på en enkätundersökning som genomfördes under hösten 2017 med 140 ledare för nationella och regionala organisationer i det civila samhället i Sverige (N. 140). Syftet med rapporten är att ge en bred bild av dessa ledares positioner, de resurser de förfogar över, deras aktiviteter och inflytande, deras erfarenheter kring ledarskap och motiv til

Holding course : Civil society organizations’ value expressions in the Swedish legislative consultation system before and after 2015

Contrary to the general trend in European countries since the 2000s, Sweden has neither restricted its migration policy nor limited the rights of migrants. This changed with the ‘refugee crisis’ of 2015 when the government introduced policy changes to curb the number of arrivals and impede the granting of residence permits. Civil society organizations are significantly involved in the reception of

Injuries and Illnesses in Swedish Paralympic Athletes - A 52-week Prospective Study of Incidence and Risk Factors

IntroductionSports‐related injuries and illnesses in Paralympic sport (SRIIPS) is a concern, but knowledge about the aetiology and risk factors is limited. The aim of this study was to describe the annual incidence, type and severity of injuries and illnesses among Swedish Paralympic athletes and to assess risk factors.MethodsSwedish Paralympic athletes (n=107) self‐reported SRIIPS every week duri

Effects of traps in the gate stack on the small-signal RF response of III-V nanowire MOSFETs

We present a detailed study of the effect of gate-oxide-related defects (traps) on the small-signal radio frequency (RF) response of III-V nanowire MOSFETs and find that the effects are clearly identifiable in the measured admittance parameters and in important design parameters such as h21 (forward current gain) and MSG (maximum stable gain). We include the identified effects in a small-signal mo

Vertical nanowire III–V MOSFETs with improved high-frequency gain

High-frequency performance of vertical InAs/InGaAs heterostructure nanowire MOSFETs on Si is demonstrated for the first time for a gate-last configuration. The device architecture allows highly asymmetric capacitances, which increases the power gain. A device with Lg = 120 nm demonstrates fT = 120 GHz, fmax = 130 GHz and maximum stable gain (MSG) = 14.4 dB at 20 GHz. These metrics demonstrate the

Electrical Characterisation of III-V Nanowire MOSFETs

The ever increasing demand for faster and more energy-efficient electricalcomputation and communication presents severe challenges for the semiconductor industry and particularly for the metal-oxidesemiconductorfield-effect transistor (MOSFET), which is the workhorse of modern electronics. III-V materials exhibit higher carrier mobilities than the most commonly used MOSFET material Si so that the

Process synthesis and simulation of furfural production from rice straw biowaste

Rice straw is regarded as one of the main cereal straws that are produced every year in substantial amounts. Typically, rice straw is burned by farmers as they could not find a more promising technique to dispose it. This burning produces particulates and carbon monoxide causing many adverse effects on the environment and the public health, and finding a way to efficiently utilise this biowaste re
