A Hardware-in-the-Loop Simulator for mmWave Massive MIMO Using PYNQ Framework

Massive multiple-input multiple-output (MIMO) plays an important role in beyond 5G systems to support high data rate and low latency, especially operating at millimeter-wave frequency bands. In traditional software-based simulators, the simulation time increases exponentially with the number of base station antennas and served users. We propose a hardware-in-loop simulator that combines the flexib

Raising the bar : genus-specific nested PCR improves detection and lineage identification of avian haemosporidian parasites

Avian haemosporidian parasites are useful model organisms to study the ecology and evolution of parasite-host interactions due to their global distribution and extensive biodiversity. Detection of these parasites has evolved from microscopic examination to PCR-based methods, with the mitochondrial cytochrome b gene serving as barcoding region. However, standard PCR protocols used for screening and

The gender minority stress model and/or cisnormativity? : The need for pluralistic theoretical perspectives in improving trans health and medicine

The minority stress model has become a well-used framework to explain and analyse health among LGBTQ people, and specifically among transgender and gender-diverse people (TGD), when it is sometimes called ‘the gender minority stress model’. Scholars have argued the need for critical discussions about some of the assumptions underlying the gender minority stress model and how it has been used and d

Access to and quality of elective care : a prospective cohort study using hernia surgery as a tracer condition in 83 countries

Background: Timely and safe elective health care facilitates return to normal activities for patients and prevents emergency admissions. Surgery is a cornerstone of elective care and relies on complex pathways. This study aimed to take a whole-system approach to evaluating access to and quality of elective health care globally, using inguinal hernia as a tracer condition. Methods: This was a prosp

What is the prospect of a perennial grain revolution of agriculture?

Agriculture has been dominated by annual plants, such as all cereals and oilseeds, since the very beginning of civilization over 10,000 years ago. Annual plants are planted and uprooted every year which results in severe disturbance of the soil and disrupts ecosystem services. Science has shown that it is possible to domesticate completely new perennial grain crops, i.e. planted once and harvestedNon-technical summary:Agriculture has been dominated by annual plants, such as all cereals and oilseeds, since the very beginning of civilization over 10,000 years ago.

Nickel phosphide is used as powder form for joining applications and therefore it is imperative to study the formation as well as interaction of Ni2P particles with Brazing with nickel-chromium-based fillers is widely used to join stainles

Towards self-reliant robots : skill learning, failure recovery, and real-time adaptation: integrating behavior trees, reinforcement learning, and vision-language models for robust robotic autonomy

Robots operating in real-world settings must manage task variability, environmental uncertainty, and failures during execution. This thesis presents a unified framework for building self-reliant robotic systems by integrating symbolic planning, reinforcement learning, behavior trees (BTs), and vision-language models (VLMs).At the core of the approach is an interpretable policy representation based

Safety and Reliability for Autonomous Robots in Dynamic Environments

Autonomous robots must operate reliably and safely under uncertain, dynamic conditions over extended periods. To ensure such operational robustness, it is vital that both developers and operators can clearly and verifiably specify functional requirements and safety constraints throughout the robot software lifecycle. My research targets different layers of robot operational safety: early error det

Enhanced classification performance using deep learning based segmentation for pulmonary embolism detection in CT angiography

Purpose: To develop a deep learning-based algorithm that automatically and accurately classifies patients as either having pulmonary emboli or not in CT pulmonary angiography (CTPA) examinations. Materials and methods: For model development, 700 CTPA examinations from 652 patients performed at a single institution were used, of which 149 examinations contained 1497 PE traced by radiologists. The n

Exploring the nanoscale mechanisms of Ni-P system to examine the suitability as joining material for high temperature applications

Nickel phosphide is a valuable material in high-temperature brazing and joining applications, offering excellent thermal stability for temperatures up to 400°C. Nickel phosphide is used as powder form for joining applications and therefore it is imperative to study the formation as well as interaction of Ni2P particles with adjacent particles in an in-situ/in-operando manner for high temperature j

Examenskonserten - Är den utvecklande?

Den 31 mars 2006 genomförde jag min examenskonsert ackompanjerad av Spårvägen Malmö. Efteråt började jag fundera på om orkestern fick ut lika mycket av själva konserten och förarbetet som jag. För att ta reda på detta genomförde jag en enkätundersökning med orkestern samt intervjuer med utvalda musikanter. Arbetet tar upp relationen mellan amatörer och professionella och hur man väljer repertoar i
