We give a proof of the Nirenberg-Treves conjecture: that local solvability of principal type pseudo-differential operators is equivalent to condition (Psi). This condition rules out sign changes from - to + of the imaginary part of the principal symbol along the oriented bicharacteristics of the real part. We obtain local solvability by proving a localizable a priori estimate for the adjoint opera

Succinate:quinone reductase (SQR) is an enzyme in the respiratory system of aerobic cells. SQR catalyzes two reactions, the oxidation of succinate to fumarate and the reduction of quinone to quinol. These reactions are coupled by electron transfer within the enzyme from the site of succinate oxidation to the site of quinone reduction. Some enzymes reduce ubiquinone (exergonic reaction) whereas oth

Classifying images of HEp-2 cells from indirect immunofluorescence has important clinical applications. We have developed an automatic method based on random forests that classifies an HEp-2 cell image into one of six classes. The method is applied to the data set of the ICPR 2012 contest. The previously obtained best accuracy is 79.3% for this data set, whereas we obtain an accuracy of 97.4%. The

Popular Abstract in English Wild fruits trees species are widely distributed throughout the African countries. Many of these trees species produce fruits, which are used by the local communities to greater or less degrees. The importance of wild fruits in the diet depends to a large extent on the availability of the fruits, since cultivated fruit trees are not particularly common in the dry regionAbstract Wild fruit trees have significant cultural and socio-economic value in rural areas of Mozambique. Most of the wild fruits are seasonal and are available mainly in the wet season. Generally they have a short shelf-life and are eaten fresh or after minimal processing; the most common method of preservation is sun-drying. The fruits of Adansonia digitata, Landolphia kirkii, Salacia kraussii,

Syftet med denna arbetsrapport är att undersöka hur renblåsningens funktion påverkas av diffusion hos gaser och partiklar. Regenerativ värmeväxling med rotor har ett varvtalsbero- ende överföringsflöde med frånluft till tilluft, vilket elimineras med ett renblåsningsflöde. Det är inte självklart att en rotor blir renblåst även om renblåsningsvolymen för en rotorkanal är större än rotorkanalens

Bakgrund till samt redogörelse för inrättandet av Lunds universitets årsskrift 1864 som ett forum för vetenskaplig publicering.

We consider the problem of computing the product of two n×n Boolean matrices A and B. For an n×n Boolean matrix C, let GC be the complete weighted graph on the rows of C where the weight of an edge between two rows is equal to its Hamming distance, i.e., the number of entries in the first row having values different from the corresponding entries in the second one. Next, letMWT(C) be the weight of a

What happens when economies 'heat up'? This book looks at the 1990s, years of intense economic experimentation, when buzz words such as 'network society', 'the experience economy', 'creative cities' and 'glocalization' were everywhere. A fascinating perspective on 'The New Economy' emerges as the authors explore the worlds of coolhunters, biotech brokers, career coaches, software entrepreneurs and

This article discusses what it meant for Jesus’ disciples to be disciples of a prophet and, consequently, what the presence of such prophet-disciples can tell us about his mission. This is done by situating the Gospel material about Jesus’ disciples in the context of early Jewish conceptions of prophetic discipleship, ultimately based on the Old Testament narratives about ancient Israelite prophet
