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. Non-coding RNAs and Extracellular Vesicles in Cutaneous Squamous Cell Carcinoma

   Author : Chen Li; Andor Pivarcsi; Gareth Inman; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cutaneous squamous cell carcinoma; microRNA; long non-coding RNA; extracellular vesicle;

   Abstract : Cutaneous squamous cell carcinoma (cSCC) ranks among the most widespread malignancies with metastatic potential. Investigating the molecular mechanism of tumorigenesis will enhance our understanding of cSCC. Aberrant expression of non-coding RNAs has been extensively reported in human cancers. READ MORE

5. 3. Low Noise Oscillator in ADPLL toward Direct-to-RF All-digital Polar Transmitter

   Author : Jian Chen; Li-Rong Zheng; Fredrik Jonsson; Hannu Tenhunen; Georges Gielen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; all-digital; digitally-intensive; frequency modualtion; phase modulation; amplitude modulation; polar; transmitter; oscillator; digital controled oscillator; DCO; VCO; voltage controled oscillator; class-C oscillator; class-D PA; ADPLL; phase noise; RF; CMOS.;

   Abstract : In recent years all-digital or digitally-intensive RF transmitters (TX) have attracted great attention in both literature and industry. The motivation is to implement RF circuits in a manner suiting advanced nanometer CMOS processes. To achieve that, information is encoded in the time-domain rather than voltage amplitude. READ MORE

6. 4. Essays on Female Policymakers and Policy Outcomes

   Author : Li-Ju Chen; Per Pettersson-Lidbom; Lena Edlund; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; education; female legislator; political economy; distance to the technological frontier; gender quotas; policy outcomes; Economics; Nationalekonomi; Economics; nationalekonomi;

   Abstract : The thesis consists of three papers, summarized as follows. "Female Policymakers and Educational Expenditures: Cross-Country Evidence" This paper investigates the influence of women in politics on decision-making using public educational expenditures as the outcome of interest.

7. 5. Ultra-low latency communication for 5G transport networks

   Author : Jun Li; Jiajia Chen; Chan Vincent; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : The fifth generation (5G) mobile communication system is envisioned to serve various mission-critical Internet of Thing (IoT) applications such as industrial automation, cloud robotics and safety-critical vehicular communications. The requirement of the end-to-end latency for these services is typically within the range between 0. READ MORE
