2. 1. Ulnar fractures and ligament injuries of the wrist

   Author : Maria Moloney; Lars Adolfsson; Simon Farnebo; Niels Schep; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ulna; Fracture; Wrist; PRWE; Classification;

   Abstract : Falling over on an outstretched hand with the wrist extended is a common accident that can cause a multitude of injuries in the wrist. Research has mainly focused on distal radius fractures while injuries of the distal ulna and adjacent ligaments have taken a back seat. READ MORE

4. 2. Low-Voltage Analog-to-Digital Converters and Mixed-Signal Interfaces

   Author : Prakash Harikumar; Jacob Wikner; Atila Alvandpour; Dag T. Wisland; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Analog-to-digital converters (ADCs) are crucial blocks which form the interface between the physical world and the digital domain. ADCs are indispensable in numerous applications such as wireless sensor networks (WSNs), wireless/wireline communication receivers and data acquisition systems. READ MORE

5. 3. Linearity Enhancements of Receiver Front-end Circuits for Wireless Communication

   Author : Mohammed Abdulaziz; Institutionen för elektro- och informationsteknik; []
   Keywords : CMOS; receivers; operational transconductance amplifiers; filtering; channel select filters; stability; low noise amplifiers; linearization; carrier aggregation; spectrum sensing;

   Abstract : Technology scaling in advanced CMOS nodes has been very successful in reducing the cost and increasing the operating frequency, however, it has also resulted in reduced transistor intrinsic gain and increased thermal noise coefficient, and most importantly, deteriorated linearity performance. At the same time, advanced wireless communication standards offer ever increasing data rates and pose more stringent requirements on coexistence, leading to very stringent linearity requirements.

6. 4. Investigation of Sigma-Delta-over-Fiber for High-Capacity Wireless Communication Systems

   Author : Husileng Bao; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; millimeter-wave; multipleinput- multiple-output; remote radio head; Radio-over-fiber; central unit;

   Abstract : The advent of beyond-5G (B5G) and 6G technologies brings increases in wireless devices and their applications. Although massive multiple-input-multiple-output (MIMO) delivers high-capacity services using co-located MIMO (CMIMO) technology, distributed MIMO (D-MIMO) technology offers a more uniform user service.
