  1. 1. Simplicity within Complexity : Understanding dynamics of cellular networks by model reduction

    Author : Olivia Eriksson; Jesper Tegnér; Arne Elofsson; Yishao Zhou; Stefan Bornholdt; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; model reduction; cellular networks; dynamical modules; delayed piecewise linear; systems biology; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : Cellular networks composed of interactions between genes, proteins and metabolites, determines the behavioural repertoire of the cell. Recent developments in high-throughput experimental techniques and computational methods allow static descriptions of these networks on a genome scale. READ MORE

  2. 2. Multiantenna Cellular Communications : Channel Estimation, Feedback, and Resource Allocation

    Author : Emil Björnson; Björn Ottersten; Mats Bengtsson; Marios Kountouris; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; channel estimation; limited feedback; multicell communications; resource allocation;

    Abstract : The use of multiple antennas at base stations and user devices is a key component in the design of cellular communication systems that can meet the capacity demands of tomorrow. The downlink transmission from base stations to users is particularly limiting, both from a theoretical and a practical perspective, since user devices should be simple and power-efficient, and because many applications primarily create downlink traffic (e.

  3. 3. Molecular and Cellular Complexity of Glioma : Highlights on the Double-Edged-Sword of Infiltration Versus Proliferation and the Involvement of T Cells

    Author : Demet Çağlayan; Bengt Westermark; Maria Ferletta; Ana Martin-Villalba; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glioma; Sox2; Sox21; Snail; Bone morphogenetic protein; Sleeping Beauty; Gliomatosis Cerebri; T lymphocytes; T regulatory lymphocytes; Oncology; Onkologi; Biology; Biologi;

    Abstract : Glioblastoma multiforme (GBM), the most common and malignant brain tumor, is characterized by high molecular and cellular heterogeneity within and among tumors. Parameters such as invasive growth, infiltration of immune cells and endothelial proliferation contribute in a systemic manner to maintain the malignancy. READ MORE

  4. 4. On Hardware Implementation of Discrete-Time Cellular Neural Networks

    Author : Suleyman Malki; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circuit switching; Network on Chip; Vein feature extraction; Velocity measurement; Discrete-Time Cellular Neural Network; Switched broadcast; Serialized broadcast; Cellular Neural Network; Field- Programmable Gate-Array; Image processing.;

    Abstract : Cellular Neural Networks are characterized by simplicity of operation. The network consists of a large number of nonlinear processing units; called cells; that are equally spread in the space. READ MORE

  5. 5. Amperometric Biosensors for Detection of Analytes in Cellular Models

    Author : Jaime Castillo Leon; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Simultaneous detection; Bienzyme electrode; Amperometric biosensors; Cellular models; Analytisk kemi; Electrochemistry; Elektrokemi;

    Abstract : Various biological problems such as disease mechanisms, drug development and toxicological studies motivated the introduction of cellular models that today also represent an alternative for reducing the use of animals in controversial medical and pharmaceutical experiments. Cells are complex matrices where several processes occur simultaneously. READ MORE
