  2. 1. Towards Radio-Environment Aware IoT Networks : Wireless Coexistence Methods for Low-complexity Devices

    Author : Simone Grimaldi; Mikael Gidlund; Aamir Mahmood; Tingting Zhang; Georgios Z. Papadopoulos; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IoT; Industrial IoT; Interference; Machine Learning; Wireless Coexistence; Wireless Networks;

    Abstract : Wireless technologies for short-range communication play a central role in the massive diffusion of the Internet of Things (IoT) paradigm. Such communication solutions rely extensively on the availability of unlicensed spectrum in the form of bands for industrial, scientific, and medical (ISM) applications. READ MORE

  4. 2. Genomic studies of sex differences : On mutations, recombination, and sexual antagonism in songbirds

    Author : Hongkai Zhang; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sex differences; mutation; recombination; sexual conflict; sexual antagonism; sexually antagonistic selection; Great reed warbler; Acrocephalus arundinaceus;

    Abstract : Many organisms have separate sexes, i.e., males and females. The presence of separate sexes causes sex-specific selection regimes and sexual antagonism, which can lead to sex differences in morphology, physiology, and behaviours. READ MORE

  5. 3. Hankel operators and Plancherel formula

    Author : Genkai Zhang; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : We consider the natural unitary action of the group SU(d, 1) on the Hilbert space L2(B,d/j,\), where B is the unit ball of C , dfi\ is the measure K(z, z)~~*+ï dm(z), and K(z, z) the reproducing kernel of the Bergman space on B. For A >—1 and not an integer, a Plancherel formula is proved for this action and, in particular, an explicit formula for the correponding Plancherel measure is found. READ MORE

  6. 4. Detection of Bio-analytes with Streaming Current : From Fundamental Principles to Novel Applications

    Author : Siddharth S. Sahu; Apurba Dev; Shi-Li Zhang; Michel Calame; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Streaming current; Electrokinetic biosensor; Size and Charge effects; membrane protein profiling of extracellular vesicles; sandwich immunoassay; charge-labelled antibodies; multiplexed detection; exosome heterogeneity;

    Abstract : A biosensor based on streaming current is a new and relatively unexplored subject with significant potential. This thesis attempts to gain a deeper understanding of the governing principles, and then exploit them to further improve its performance as well as develop novel applications. READ MORE
