  2. 1. Renal cell death in urinary tract infections : role of E. coli toxins

    Author : Ming Chen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Pyelonephritis; Escherichia coli toxins; ERK; LPA; cell death; carbon monoxide; hemolysin; nitric oxide; heme oxygenase-1; dexamethasone; kidney development;

    Abstract : Febrile urinary tract infections (UTI) are common bacterial illnesses in children. Several follow up studies have shown that 10-15 % of infants with pyelonephritis will develop permanent renal damage, i.e., renal scars, which in turn may lead to chronic diseases such as hypertension and renal insufficiency.

  4. 2. Channel Prediction Based On Sinusoidal Modeling

    Author : Ming Chen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Long range channel prediction is considered as one of the most important enabling technologies to future wireless communication systems. The prediction of Rayleigh fading channels is studied in the frame of sinusoidal modeling in this thesis. A stochastic sinusoidal model to represent Rayleigh fading channel is proposed. READ MORE

  5. 3. Radio Channel Prediction Based on Parametric Modeling

    Author : Ming Chen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless communications; channel prediction; GLRT; CRLB; NLLS; polynomial phase signal; Kalman filter; NILS.; sinusoidal modeling; channel modeling; MIMO;

    Abstract : Long range channel prediction is a crucial technology for future wireless communications. The prediction of Rayleigh fading channels is studied in the frame of parametric modeling in this thesis.Suggested by the Jakes model for Rayleigh fading channels,deterministic sinusoidal models were adopted for long rangechannel prediction in early works.

  6. 4. Structural studies of enzymes regulating bacterial life style and cell wall biogenesis

    Author : Ming Wei Chen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Bacteria can adapt to different biotic and abiotic environments by changing their life style, switching between sessile or motile, free-living or community-bound, virulent or dormant states. Each bacterium also faces the challenges of maintaining a protective barrier while growing, replicating and responding to environmental changes. READ MORE

  7. 5. Transient Control for Leader-follower Multi-agent Systems with Application to Spatiotemporal Logic Tasks

    Author : Fei Chen; Dimos V. Dimarogonas; Jana Tumova; Ming Cao; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-agent systems; leader-follower networks; transient constraints; temporal logics; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Over the past few decades, significant research has been directed towards addressing the problem of distributed control of multi-agent systems. The overall tasks include consensus, formation, flocking, and coverage control with the wide applications in multi-robot coordination, manufacturing and intelligent transportation systems. READ MORE
