SPECIES-SPECIFIC TRACKS of animals can be an effective way of mapping species that are hard to find even if they are present. We used observations of sap rows on trees to calculate densities of Eurasian Three-toed Woodpeckers Picoides tridactylus. We surveyed 14 fixed routes in northern Sweden below the montane forest for sap rows during the autumn of 2020. We used our observations of fresh sap ro
Connected Autonomous Vehicles (AV)s can transform urban transportation systems and have the potential to improve the safety and efficiency, since human errors and distractions are removed. However, these systems are vulnerable to model uncertainties, communication impairments associated with the wireless communication, and external disturbances. As a result, vehicles need to drive at low speed and
The learning with errors (LWE) problem is one of the main mathematical foundations of post-quantum cryptography. One of the main groups of algorithms for solving LWE is the Blum–Kalai–Wasserman (BKW) algorithm. This paper presents new improvements of BKW-style algorithms for solving LWE instances. We target minimum concrete complexity, and we introduce a new reduction step where we partially reduc
In this paper, we present a side-channel attack on a first-order masked implementation of IND-CCA secure Saber KEM. We show how to recover both the session key and the long-term secret key from 24 traces using a deep neural network created at the profiling stage. The proposed message recovery approach learns a higher-order model directly, without explicitly extracting random masks at each executio
Soil microbes play an important role in governing global processes such as carbon cycling, but it is challenging to study them embedded in their natural environment and at the single cell level due to the opaque nature of the soil. Nonetheless, progress has been achieved in recent years towards visualizing microbial activities and organo-mineral interaction at the pore scale, especially thanks to
There is great interest in measuring immune function in wild animals. Yet, field conditions often have methodological challenges related to handling stress, which can alter physiology. Despite general consensus that immune function is influenced by handling stress, previous studies have provided equivocal results. Furthermore, few studies have focused on long-lived species, which may have differen
In this thesis, we address three main security problems related to cryptography andcloud storage. To tackle the challenge posed by a quantum computer, we needencryption that is resistant to quantum computers. This category of cryptographyis called post-quantum cryptography. In the first paper, we solve a challengein one of the lattice-based cryptographic protocols called Nth-degree Truncatedpolyno
The advancement of mobile technologies and their ability to utilize the Global Positioning System (GPS) to accurately locate their substantial number of users, prompt Location-Based Services (LBS) significantly. Ride-sharing is a popular means of transportation that utilizes LBS. With the rapid development of smart cities and their impact on addressing the critical issues of urban life such as tra
"Storsjöodjuret”, eller “The Great Lake Monster”, är ett undflyende fenomen i sjön Storsjön, belägen i landskapet Jämtland i norra Sverige. Denna avhandling i ämnet humanekologi undersöker hur det sammankopplingar av det sociala, det kulturella, det historiska och det lokala påverkar formandet av detta svenska kryptid, eller “dolda djur”. Syftet med studien är att visa hur detta vetenskapligt ännu
We present a synchronized multisensory dataset for accurate and robust indoor localization: the Lund University Vision, Radio, and Audio (LuViRA) Dataset. The dataset includes color images, corresponding depth maps, inertial measurement unit (IMU) readings, channel response between a 5G massive multiple-input and multiple-output (MIMO) testbed and user equipment, audio recorded by 12 microphones,
Objective To compare experiences of the second stage of labour in women randomised to assistance by one or by two midwives to reduce severe perineal trauma (SPT). Design Analysis of a secondary outcome within the Swedish Oneplus multicentre randomised trial. Setting Five obstetric units in Sweden between December 2018 and March 2020. Participants Inclusion criteria in the Oneplus trial were women
The Amsterdam 2022 International Consensus Statement on Concussion in Sport (6th International Conference on Concussion in Sport) was the first Concussion in Sport Group (CISG) consensus to consider the para athlete.1 To date, a lack of research in para sport on most aspects of concussion has prevented the development of evidence-informed consensus on any aspects of concussion care for para athlet
Declarative approaches to program analysis promise a number of practical advantages over imperative approaches, from eliminating manual worklist management to increasing modularity. Reference Attribute Grammars (RAGs) are one such approach. One particular advantage of RAGs is the automatic generation of on-demand implementations, suitable for query-based interactive tooling as well as for client a
Purpose: The survival rate of breast cancer for women in low- and middle-income countries is poor compared with that in high-income countries. Point-of-care ultrasound (POCUS) combined with deep learning could potentially be a suitable solution enabling early detection of breast cancer. We aim to improve a classification network dedicated to classifying POCUS images by comparing different techniqu
Background: Elderly individuals with chronic conditions or acute illnesses are major drivers of hospitalization, with frail patients frequently utilizing emergency department (ED) services. To ease this burden, many countries offer home-based medical services. In Region Halland, Sweden, a mobile team intervention in municipal home care (MHC) was introduced to support frail elderly patients. This s
BACKGROUND: The strawberry tortrix, Acleris comariana (Lepidoptera: Tortricidae), is a destructive pest of strawberry in Denmark and southern Sweden. The efficacy of pheromone-based communication disruption of the species was examined in crop fields in southern Sweden. Due to the high cost of purchasing or synthesizing the pheromone (E)-11,13-tetradecadienal, lower quantities were applied per ha c
NTRU is a public-key cryptosystem, where the underlying mathematical problem is currently safe against large-scale quantum computer attacks. The system is not as well investigated, as for example RSA, and the company behind NTRU has created the NTRU Challenges, to remedy this. These challenges consist of 27 different public keys of increasing size, where the task in each challenge is to calculate
