A Note on the Smith Predictor
Energy-based interference analysis of heterogeneous packet radio networks
While the use of radio technology for wireless data communications has increased rapidly, the wide variety of radio interfaces being used has made interference investigations hard to perform. With that in mind, we present a novel approach for analyzing packet radio communications, applicable to interfering heterogeneous networks, which leads to tractable analytical expressions. The core of the app
Techniques for implementing embedded domain specific languages in dynamic languages
Computer programming should be expressing the complicated in easily understandable parts. General languages provide tools and abstractions that allow many different problems to be formulated and solved. Unfortunately, these abstraction only rarely match the problem area precisely, resulting in solutions that are obscured by the need for support code unrelated to the problem. This can be avoided, b
Tuning energy transfer in the peridinin-chlorophyll complex by reconstitution with different chlorophylls
In vitro studies of the carotenoid peridinin, which is the primary pigment from the peridinin chlorophyll-a protein (PCP) light harvesting complex, showed a strong dependence on the lifetime of the peridinin lowest singlet excited state on solvent polarity. This dependence was attributed to the presence of an intramolecular charge transfer (ICT) state in the peridinin excited state manifold. The I

Analysis of promoter regions of co-expressed genes identified by microarray analysis
Background: The use of global gene expression profiling to identify sets of genes with similar expression patterns is rapidly becoming a widespread approach for understanding biological processes. A logical and systematic approach to study co-expressed genes is to analyze their promoter sequences to identify transcription factors that may be involved in establishing specific profiles and that may

Integritetsfrågor i arbetslivet
Popular Abstract in Swedish Denna avhandling behandlar ämnesområdet integritet i arbetslivet. Individer i ett modernt samhälle har anspråk på respekt eller icke angrepp inom sitt intresseområde. Arbetslivet utgör ett exempel på ett sådant område. Min utgångspunkt då jag behandlar ämnet är främst individens (arbetstagarens) prima-facie anspråk på respekt, icke angrepp inom sitt intresseområde. IntThis dissertation deals with personal privacy in working life. Humans have legitimate expectations and claims to respect for and non-interference with personal privacy in many areas and stages of life. The work place is just one of them. The point departure when dealing with privacy matters at the workplace is primarily the claim by individual employees to respect for and non-interference with the
A highly sensitive flow-through amperometric immunosensor based on the peroxidase chip and enzyme-channeling principle
A concept based on the Peroxidase-chip (P-chip), antibody co-immobilization, competitive and enzyme-channeling principle was exploited to develop an integrated flow-through amperometric biosensor for detection of environmental pollutants such as s-triazine herbicides. In this concept, recombinant peroxidase is immobilized on the gold electrode (P-chip) in such a way that direct electron transfer i
Borrowings - A Source of Innovation in the Class of Interjections
The present article is part of a larger project investigating the various types of linguistic change that affected and might affect the word class traditionally known under the label of interjection. The results of our research, as outlined here, concern the inter-linguistic mobility of units, i.e., borrowings, which in the source language can be (but not necessarily) interjections, and which are

Ultrafast exciton dynamics in molecular systems
The theory of subpicosecond Frenkel exciton dynamics in molecular systems is reviewed with emphasis on a stepwise imp loved description of the coupling to intra- and intermolecular vibrations. After introducing the concept of multiexciton states the motion of electronic Frenkel excitons as they appear in light harvesting antennae of photosynthetic organisms is discussed. The description is based o
Assignment of the surface core-level shifts to the surface layers of Be(10(1)over-bar0)
Photoemission studies and layer resolved Korringa-Kohn-Rostoker (KKR) multiple scattering calculations are used to find the assignment of the surface core-level shifts to the top layers of the Be(10 (1) over bar0) surface. Striking similarities between experimental and calculated data make it possible to assign the largest shift to layer two, the second largest shift to layers three and four, and
The metabolic syndrome: a glance at its history.
Extracellular ATP: a growth factor for vascular smooth muscle cells
1. Extracellular adenosine triphosphate (ATP) is mitogenic for vascular smooth muscle cells (VSMC) and stimulates several events that are important for cell proliferation: DNA synthesis, protein synthesis, increase of cell number, immediate early genes, cell-cycle progression, and tyrosine phosphorylation. 2. Receptor characterization indicates mitogenic effects of both P2U and P2Y receptors. The
Coupling between lateral modes in a vertical resonant tunneling structure
We present experimental results and theoretical calculations of the vertical electron transport through a laterally constricted resonant tunneling transistor. Current-voltage measurements at 4.2 K show numerous current peaks that exhibit a complex dependence on the applied gate voltage. A scattering-matrix approach combined with the Landauer formalism was used to perform quantum mechanical calcula
Effect of high-fat diet, surrounding temperature, and enterostatin on uncoupling protein gene expression
Nonshivering thermogenesis induced in brown adipose tissue (BAT) during high-fat feeding is mediated through uncoupling protein 1 (UCP1). UCP2 is a recently identified homologue found in many tissues. To determine the role of UCP1 and UCP2 in thermoregulation and energy balance, we investigated the long-term effect of high-fat feeding on mRNA levels in mice at two different ambient temperatures. W
Imagery in a process perspective
Since many of the data offered in his text, and many of his conclusions, give the indication of agreeing with what is more or less loosely termed process psychology, I would like to try my own hand at drawing a theoretical sketch of how images can be conceptualized within a theory of perception. The sketch agrees basically with what Quill, inspired by Whitehead, takes to be the requirements of a t
Susceptibilities of Mycobacterium marinum to Gatifloxacin, Gemifloxacin, Levofloxacin, Linezolid, Moxifloxacin, Telithromycin, and Quinupristin-Dalfopristin (Synercid) Compared to Its Susceptibilities to Reference Macrolides and Quinolones.
The susceptibility pattern of Mycobacterium marinum was determined. Quinupristin-dalfopristin and telithromycin were less active than clarithromycin. Linezolid showed good antimicrobial activity at clinically achievable concentrations. Gatifloxacin, levofloxacin, and moxifloxacin displayed activities similar to those of ciprofloxacin. Gemifloxacin was less active. The Etest method showed variable
