We present dc and RF characterization of InAs nanowire field-effect transistors (FETs) heterogeneously integrated on Si substrates in a geometry suitable for circuit applications. The FET consists of an array of 182 vertical InAs nanowires with about 6-nm HfO high-gate dielectric and a wrap-gate length of 250 nm. The transistor has a transconductance of 155 mS/mm and an on-current of 550 mA/mm at

Aims: Urinary 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodG) is a widely used biomarker of oxidative stress. However, variability between chromatographic and ELISA methods hampers interpretation of data, and this variability may increase should urine composition differ between individuals, leading to assay interference. Furthermore, optimal urine sampling conditions are not well defined. We perform

Objective. With the increase in robotic-assisted laparoscopic surgery there is a concomitant rising demand for training methods. The objective was to establish face and construct validity of a novel virtual reality simulator (dV-Trainer, Mimic Technologies, Seattle, WA) for the use in training of robot-assisted surgery. Methods. A comparative cohort study was performed. Participants (n = 42) were

The objectives were to investigate (i) the forms and release pattern of P from an ash-rich biochar-amended sandy soil; (ii) the transformation of biochar P in a soil-plant system. Several methodologies (a bioassay test, soluble P extractions, a sequential P fractionation and successive P extractions via resin strips) were used to study the bioavailability and transformation of P in a sandy soil

This paper presents a structured methodology for the constrained multi-objective optimization (MO) of a continuous cross-flow atomic layer deposition (ALD) reactor model with temporal precursor pulsing. The process model has been elaborated and experimentally validated in the first two papers of this series (33 and 34). A general constrained MO problem (MOP) was formulated to simultaneously optimi

The inverse problem for Schrodinger operators on metric graphs is investigated in the presence of magnetic field. Graphs without loops and with Euler characteristic zero are considered. It is shown that the knowledge of the Tachmarsh-Weyl matrix function (Dirichletto-Neumann map) for just two values of the magnetic field allows one to reconstruct the graph and potential on it provided a certain ad

Popular Abstract in Swedish Hepatit C är idag den ledande orsaken till kronisk leversjukdom i västvärlden och även den vanligaste anledningen till levertransplantation. Sjukdomen orsakas av hepatit C-virus (HCV) och överförs i de flesta fall via blod. Majoriteten av de smittade (50-80%) kommer att utveckla en kronisk HCV-infektion. Den ständigt pågående inflammation som virusinfektionen orsakar iThe hepatitis C virus (HCV) is a blood borne virus effectively spread through injection practices. Consequently, people who inject drugs (PWID) are at the center of the current HCV epidemic in industrialized countries, with regards both to prevalence and incidence. Through progressive liver fibrosis, chronic HCV infection conveys a substantial risk of liver cirrhosis and end-stage liver disease. T

Sweden experienced an increase in the ratio of granted patents to research and development spending (R&D) between 1989 and 1998, a period when R&D spending grew rapidly. The ratio of patents granted to R&D spending (research productivity) increased by 40% over the period, and the ratio of quality-adjusted patents to R&D exhibited an even more impressive increase of 60%. Sectors wit

A hybrid plasmonic waveguide consisting of a high-index dielectric core embedded inside a rectangular-shaped metallic trench is proposed and its guiding properties are investigated at the wavelength of 1550 nm. Numerical simulations based on the finite element method have demonstrated that the introduced dielectric core could greatly reduce the modal loss of the metal trench while maintaining stro

Solution and adsorption properties of both charged and uncharged bottle-brush polymers have been investigated. The solution conformation and interactions in solution have been investigated by small-angle scattering techniques. The association of the bottle-brush polymers with anionic surfactants has also been studied. Surfactant binding isotherm measurements, NMR, surface tension measurements, as

Popular Abstract in Swedish Under den nuvarande värmeperioden (holocen) som inleddes för ca 11 600 år sedan, har klimatet i den nordatlantiska regionen varierat på både korta och långa tidsskalor. Orsaken till dessa variationer är många och komplexa, men kan till viss del relateras till temporära förändringar i havsströmmar och den atmosfäriska cirkulationen. Den termohalina cirkulationen, som delThe North Atlantic region has experienced significant climate fluctuations during the Holocene. It has been shown that these fluctuations affected the terrestrial environment in Iceland, including its glaciers and ice caps. However, the full Holocene development of Icelandic glaciers, including the large Vatnajökull ice cap and its outlet glaciers, is not fully known. In this thesis, a sediment se

Cyber-physical systems react on events reported by sensors and interact with objects of the real world according to their current state and their view of the world. This view is naturally represented by a model which is continuously analysed and updated at runtime. Model analyses should be ideally concise and efficient, requiring well-founded, comprehensible implementations with efficient reasonin

With predicted decreases in genetic diversity and greater genetic differentiation at range peripheries relative to their cores, it can be difficult to distinguish between the roles of current disturbance versus historic processes in shaping contemporary genetic patterns. To address this problem, we test for differences in historic demography and landscape genetic structure of coastal giant salaman

Popular Abstract in Swedish Avhandlingen Optimization of Low-Level Controllers and High-Level Polymer Grade Changes är inom ämnesområdet reglerteknik. Det centrala i ämnet reglerteknik är att styra ett system, såsom en motor, ett teleskop eller en kemisk reaktor, så att det uppför sig på ett önskvärt sätt. Detta görs genom att använda mätningar av systemet, en algoritm som beräknar hur systemet sTwo design problems at different levels in the control hierarchy are considered; optimization of robust low-level controllers with constrained control signal activity and optimization of economical high-level polyethylene grade changes. As for the first design problem, a constraint on control signal activity due to measurement noise is presented and used when optimizing and comparing PI/PID contr

Abstract in UndeterminedCytomegalovirus (CMV) causes severe sequelae in congenitally infected newborns and may cause life-threatening disease in immuno-deficient patients. Recent findings demonstrate the possibility to alleviate the disease by infusing intravenous immunoglobulin G (IgG) preparations, indicating that antibodies are an effective therapeutic option. Modern molecular methodologies, li

Recently, there has been much interest in activity-induced phase separations in concentrated suspensions of “active Brownian particles” (ABPs), self-propelled spherical particles whose direction of motion relaxes through thermal rotational diffusion. To date, almost all these studies have been restricted to 2 dimensions. In this work we study activity-induced phase separation in 3D and compare the

The nanoindentation response of empty and filled viral capsids is modelled using three dimensional finite element analysis. Simulation with two different geometries, spherical and icosahedral, are performed using the finite element code Abaqus. The capsids are modeled as non-linear Hookean elastic and both small and large deformation analysis is performed. Force-indentation curves for three differ

Braided convolutional codes (BCCs) form a class of iteratively decodable convolutional codes that are constructed from component convolutional codes. In braided code division multiple access (BCDMA), these very efficient error correcting codes are combined with a multiple access method and inherent interleaving for channel diversity exploitation into one single scheme. In this paper, we describe t
