We have successfully embedded a metal gate in-between two resonant tunneling double barrier heterostructures (RTD), thus realizing a three dimensional resonant tunneling transistor. The gate is placed 30 nm above and 100 below the two RTD's, respectively. The asymmetric gate allows for a unique control of the current-voltage characteristics, not only controlling the peak current but also the peak
When adapting environments for the physically disabled, it is important to encourage and activate not only the person concerned, but also other people involved or affected. A computer aided planning tool has been developed to support the participation of all persons involved, as well as supporting the planner’s (e.g. an occupational therapist) design of the environment. The prototype development a
Popular Abstract in Swedish Membranproteiner är tämligen svåra att digerera med enzym som trypsin. Mindre specifika enzym såsom elastase och pepsin har dock visat sig mer effektiva. Databassökningar med dessa icke-tryptiska peptider är mindre verkningsfulla pga avsaknaden av laddning vid peptidens N-terminal och C-terminal samt brist på sekvensspecificitet. Vi beskriver en metod med specifik N-teMembrane proteins are fairly refractory to digestion especially by trypsin. Less specific proteases like elastase and pepsin are much more effective. However database searching using non-tryptic peptides is much less effective due to the lack of charge localisation at the N- and C-termini and the absence of sequence specificity. We describe a method for N-terminal specific labelling of peptides fr
A framework for operating procedure synthesis in batch processes was presented in part on of this paper. In this part, we present, iTOPS (intelligent tool for operating procedure synthesis), a knowledge based system for implementing the concepts outlined in the framework. iTOPS has been developed in Gensym's G2 expert system shell. The architecture of iTOPS, that consists of components that closel
The paper suggests a method for motion generating and stabilization with application to dynamical models for underactuated ships.
Intermittently administered PTH is known to increase bone mass in osteoporosis models. We studied its effects in bone repair and implant fixation, using histological and mechanical techniques in rats. In a bone chamber, PTH substantially increased the density of the new-formed bone, whereas there was only a minor effect on the pre-existing bone in the L5 vertebra or femur. Considering that PTH inc
The issue and distribution of IT and IS students and professionals as dependent on Gender Bias is discussed. Background and examples are presented from the IT British Industry; the UK and the Swedish Educational sectors.
The monotone rearrrangement algorithm was introduced by Hardy, Littlewood and Po ́lya as a sorting device for functions. As- suming that x is a monotone function and that an estimate xn of x is given, consider the monotone rearrangement xˆn of xn. This new estimator is shown to be uniformly consistent. Under suitable as- sumptions, pointwise limit distribution results for xˆn are obtained. The fra
Popular Abstract in Swedish Ett ökade förbrukningen av fossila bränslen kommer att accelerera den globala uppvärmningen med oöverskådlig inverkan på oss och vår miljö. Utvecklingen av alternativa, förnybara och miljömässigt rena energiformer är därför helt essentiell. En möjlig lösning är att skapa artificiell fotosyntes, där solenergi omvandlas till bränsle (till exempel vätgas) i en process där A continuing use of fossil fuels will accelerate global warning and result in severe consequences for the environment and thereby also us. Development of alternative, sustainable and environmentally friendly energy sources is therefore crucial. One approach is to create an artificial photosynthetic system that converts sunshine into fuel (e.g. hydrogen gas) by splitting water molecules. However, i
Many existing accounts of African elections assume that voters base their electoral decisions on cues and incentives that are anchored in highly stable ethnic cleavage structures. Yet several newer contributions to the study of African electoral politics have questioned the ethno-clientelistic voting thesis and highlighted other determinants of vote choice, such as class, ideology and performance
A spin-echo-modulated small-angle neutron scattering (SEMSANS) instrument in a time-of-flight (TOF) mode will be able to excel at pulsed neutron sources such as the European Spallation Source (ESS), currently under construction. This work compares experimental data from a TOF SEMSANS setup, where a spatial beam modulation of a white beam is obtained using triangular field coils, with Monte Carlo r
Antibiotic resistance (AR) poses an ever growing threat to global public health. Methods are urgently needed that simplify and accelerate the clinical detection and classification of AR. Here we describe a function-based antibiotic resistance assay (FARA) biosensing strategy. The scheme comprises three key components: i) FARA directly measures the thermal signal generated from the catalytic break-
