In this paper we study the pseudospectrum (spectral instability) of non-selfadjoint semiclassical systems of principal type, generalizing the results in the scalar case by Dencker, Sjostrand and Zworski in Comm. Pure Appl. Math. 57:3 (2004), 384-415.

The title: Forum für Sprachlose (Forum for the Speechless) indicates the overall objective of this investigation. An attempt is being made to provide a defence for the accused recipients and designated opponents of Paul’s letter to the Galatians. In order to accomplish this objec-tive, I have chosen to engage in a variety of methodological procedures. Having identified, throughout the history of t

Recent studies have shown that ability to recognize an imitated voice is affected by topic and familiarity with the person being imitated. The signal detection methods used in those studies give no specific information about the distribution of non matching positive responses (false alarms) amongst voices used as distracters (foils). This paper shows that there was a selective listener preference

This work concerns an experimental study of pressure drop and heat transfer for turbulent flow inside a U-duct with relevance for tip cooling of gas turbine blades. The U-duct models the internal blade cooling flow passages. Both friction factors and convective heat transfer coefficients were measured along the bend (turn) part of the U-duct for three different rib configuration cases, namely (a)

Popular Abstract in Swedish Proteinkinas C i nervcellsutveckling Under fosterutvecklingen ska en enda cell, den befruktade äggcellen, ge upphov till alla de högt specialiserade celler som människokroppen består av. Den process där omogna celler utvecklas till t.ex. nervceller, blodceller och muskelceller kallas differentiering. Det som avgör vad en speciell cell ska utvecklas till är bl.a. vilka sThe human neuroblastoma cell line SH-SY5Y can be induced to differentiate into a neuronal sympathetic phenotype after treatment with 16 nM 12-O-tetradecanoyl phorbol 13-acetate (TPA) in serum, or by a combination of the growth factors basic fibroblast growth factor and insulin-like growth factor-I (bFGF/IGF-I). SH-SY5Y cells stably transfected with TrkA, the nerve growth factor (NGF) receptor, dif

Classification of song similarities and differences in one bird species is a subtle problem where the actual answer is more or less unknown. In this paper, the singular vectors when decomposing the multitaper spectrogram are proposed to be used as feature vectors for classification. The advantage is especially for signals consisting of several components which have stochastic variations in the amp

Popular Abstract in English People normally associate hemoglobin with blood. It is true that the iron in the center of the hemoglobin molecule makes it excellent at carrying oxygen in the bloodstream from the lungs to every part of the body. However, seventy five years ago a hemoglobin was found in a plant. And plants do not have blood. So what is hemoglobin doing in plants? What are its functionsHemoglobins (Hb) are usually associated with blood in humans. However, these proteins are widely distributed among living organisms. In plants the most known group are the leghemoglobins. Still, other Hbs that not participate in symbiosis are also found. They are known as nonsymbiotic Hbs (nsHbs). NsHbs are divided into class-1 and class-2. In this thesis three nsHbs from sugar beet (BvHb1-1, BvHb

Numerical simulations are performed for multiphase jets in crossflow. The flow solver uses an Eulerian/Lagrangian approach. Turbulence in the gas phase is modeled in the framework of large eddy simulation. The dispersed phase is handled using Lagrangian particle tracking. The model assumptions of solvers for Lagrangian particle tracking are critically assessed for typical flow conditions of spray

Popular Abstract in Swedish I över 200 år har en rad historiker, språkmän, folklorister och arkeologer försökt att återskapa en svunnen kultur. Med hjälp av antika texter, medeltida uppteckningar, filologiska observationer och arkeologiska lämningar har de beskrivit en värld, en religion och ett folk äldre än sumererna, med vilka all historia annars sägs ha börjat. De som upprätthöll denna svunna By using ancient texts, medieval documents, philological observations, and archaeological artifacts, scholars have reconstructed a prehistorical world and religion. The people who upheld this culture have been named, inter alia, "Indo-Europeans", "Aryans", "Japhetites" and "Wiros". Yet, these people have not left any texts, no artifacts can with certainty be ascribed to them, nor do we know any in
