Virtual labeling of mitochondria in living cells using correlative imaging and physics-guided deep learning
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-28)Mitochondria play a crucial role in cellular metabolism. This paper presents a novel method to visualize mitochondria in living cells without the use of fluorescent markers. We propose a physics-guided deep learning approach for obtaining virtually labeled micrographs of mitochondria from bright-field images.

Intersecting near-optimal spaces: European power systems with more resilience to weather variability
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-03)We suggest a new methodology for designing robust energy systems. For this, we investigate so-called near-optimal solutions to energy system optimisation models; solutions whose objective values deviate only marginally from the optimum. Using a refined method for obtaining explicit geometric descriptions of these near-optimal feasible spaces, we find designs that are as robust as possible to ... -
Effectiveness of LRB in Curved Bridge Isolation: A Numerical Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-07)Lead Rubber Bearings (LRBs) represent one of the most widely employed devices for the seismic protection of structures. However, the effectiveness of the same in the case of curved bridges has not been judged well because of the complexity involved in curved bridges, especially in controlling torsional moments. This study investigates the performance of an LRB-isolated horizontally curved ... -
Towards the Neuroevolution of Low-level artificial general intelligence
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-14)In this work, we argue that the search for Artificial General Intelligence should start from a much lower level than human-level intelligence. The circumstances of intelligent behavior in nature resulted from an organism interacting with its surrounding environment, which could change over time and exert pressure on the organism to allow for learning of new behaviors or environment models. Our ... -
TFHE-rs: A library for safe and secure remote computing using fully homomorphic encryption and trusted execution environments
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-20)Fully Homomorphic Encryption (FHE) and Trusted Execution Environ-ments (TEEs) are complementing approaches that can both secure computa-tions running remotely on a public cloud. Existing FHE schemes are, however, malleable by design and lack integrity protection, making them susceptible to integrity breaches where an adversary could modify the data and corrupt the output. This paper describes how ... -
Predicting an unstable tear film through artificial intelligence
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-10)Dry eye disease is one of the most common ophthalmological complaints and is defined by a loss of tear film homeostasis. Establishing a diagnosis can be time-consuming, resource demanding and unpleasant for the patient. In this pilot study, we retrospectively included clinical data from 431 patients with dry eye disease examined in the Norwegian Dry Eye Clinic to evaluate how artificial intelligence ... -

Utilizing Alike Neighbor Influenced Similarity Metric for Efficient Prediction in Collaborative Filter-Approach-Based Recommendation System
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-17)The most popular method collaborative filter approach is primarily used to handle the information overloading problem in E-Commerce. Traditionally, collaborative filtering uses ratings of similar users for predicting the target item. Similarity calculation in the sparse dataset greatly influences the predicted rating, as less count of co-rated items may degrade the performance of the collaborative ... -
Automatic algorithm for determining bone and soft-tissue factors in dual-energy subtraction chest radiography
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-11)Lung cancer is currently the first leading cause of worldwide cancer deaths since the early stage of lung cancer detection is still a challenge. In lung diagnosis, nodules sometimes overlap with ribs and tissues on lung chest radiographic images, which are complex for doctors and radiologists. Dual-energy subtraction (DES) is a suitable solution to solve those issues. This article will develop an ... -

A Generic Undo Support for State-Based CRDTs
(Chapter; Bokkapittel, 2020-02-11)CRDTs (Conflict-free Replicated Data Types) have properties desirable for large-scale distributed systems with variable network latency or transient partitions. With CRDT, data are always available for local updates and data states converge when the replicas have incorporated the same updates. Undo is useful for correcting human mistakes and for restoring system-wide invariant violated due to long ...
