  2. 1. Silicon Nanowire Field-Effect Devices as Low-Noise Sensors

    Author : Xi Chen; Zhen Zhang; Shi-Li Zhang; Si Chen; Fengnian Xia; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon nanowire; field-effect transistor; Schottky junction gate; low frequency noise; ion sensor; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Abstract : In the past decades, silicon nanowire field-effect transistors (SiNWFETs) have been explored for label-free, highly sensitive, and real-time detections of chemical and biological species. The SiNWFETs are anticipated for sensing analyte at ultralow concentrations, even at single-molecule level, owing to their significantly improved charge sensitivity over large-area FETs. READ MORE

  4. 2. Data-Efficient Reinforcement and Transfer Learning in Robotics

    Author : Xi Chen; Patric Jensfelt; Ville Kyrki; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datalogi;

    Abstract : In the past few years, deep reinforcement learning (RL) has shown great potential in learning action selection policies for solving different tasks.Despite its impressive success in games, several challenges remain, such as designing appropriate reward functions, collecting large amounts of interactive data, and dealing with unseen cases, which make it difficult to apply RL algorithms to real-world robotics tasks.

  5. 3. Interfering with interferons : interplay between SARS-CoV-2 and interferon response

    Author : Xi Chen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) caused the coronavirus disease 2019 (COVID-19) pandemic, which has been an ongoing global health crisis. At the beginning of the pandemic, all the efforts were directed toward understanding the pathogenesis of the virus. READ MORE

  6. 4. Photothermal Effect in Plasmonic Nanostructures and its Applications

    Author : Xi Chen; Min Qiu; Sergey I. Bozhevolnyi; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plasmonic; Photothermal Effect; Silicon Photonics; Gold Nanoparticles; Physics; Fysik;

    Abstract :   Plasmonic resonances are characterized by enhanced optical near field and subwavelength power confinement. Light is not only scattered but also simultaneously absorbed in the metal nanostructures. READ MORE

  7. 5. Integrative Modeling of Epigenetic Regulation in Human Disease

    Author : Xi Lu; Xingqi Chen; Chandrasekhar Kanduri; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glioblastoma; Cross-species; Glioblastoma stem cell; Dravet syndrome; ATAC-seq; Single-cell multi-omics technology;

    Abstract : Glioblastoma is the most common and aggressive primary brain tumor. Standard of treatment prove ineffective, leading to tumor recurrence and an average survival rate of 14 months. This treatment resistance is attributed to both inter-tumor and intra-tumor heterogeneity observed across diverse tumor samples and within individual cells. READ MORE
