  2. 1. Externally positive systems : Analysis and control based on combinatorial polynomials

    Author : Liam Hamed Taghavian; Mikael Johansson; Cristian R. Rojas; Fabio Pasqualetti; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Linear systems; External positivity; Optimization; Non-overshooting control; Combinatorics; Complete monotonicity; Majorization.; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Monotonic tracking is required in many control systems, including those that cannot tolerate any overshoots and undershoots in their closed-loop responses. Classical examples are found in vehicle cruise control and liquid tank level control. READ MORE

  4. 2. Factors of importance for radiosensitivity of tonsillar carcinoma

    Author : Signe Friesland; Karolinska Institutet; Karolinska Institutet; []
    Keywords : TC; radiotherapy; radiosensitivity; complete remission; HPV; P53; MDM2; DNA-PK; DNA-PKcs; Ku86; Ku70.;

    Abstract : Radiotherapy (RT) alone or in combination with surgery is the only curative treatment of tonsillar carcinoma (TC). As distant metastases are rare the loco-regional control is the most important factor determining survival. Methods for prediction of radiocurability are lacking. READ MORE

  5. 3. On the Extension and Wedge Product of Positive Currents

    Author : Ahmad Khalid Al Abdulaali; Jan-Erik Björk; Hassine El Mir; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Closed positive currents; plurisubharmonic currents; plurisubharmonic functions; pluripolar sets; k-convex functions; wedge product of currents; Mathematics; matematik;

    Abstract : This dissertation is concerned with extensions and wedge products of positive currents. Our study can be considered as a generalization for classical works done earlier in this field. Paper I deals with the extension of positive currents across different types of sets. READ MORE

  6. 4. Malaria in infants : asymptomatic and symptomatic infections the first year of life

    Author : Akua Kyerewaa Botwe; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Malaria causes the majority of deaths in children below five years of age, but asymptomatic infections are more frequent. An understanding of the interplay of human and parasite factors which predispose to symptomatic malaria has guided clinical and preventive practices including intermittent preventive treatment and bed net usage, to reduce the global malaria burden.

  7. 5. Ploidy, cell proliferation and apoptosis in lymphoid malignancies : methodological and clinical aspects

    Author : Magdalena Czader; Karolinska Institutet; Karolinska Institutet; []
    Keywords : image cytometry; confocal cytometry; DNA ploidy; cell proliferation; ;

    Abstract : The DNA aneuploidy and proliferative activity have been previously shown to carry a clinical significance in Iymphoid malignancies. However, the application of these parameters is complicated by methodological difficulties. READ MORE
