Connecting resilience concepts to operational behaviour : A disaster exercise case study
Contemporary crisis management studies often make use of the concept of resilience. However, resilience as a term has a wide variety of meanings and has been criticized as lacking operationalization and empirical validation. The current study aimed to link resilience concepts to observable behaviour within a disaster medicine management system. Resilience concepts, captured in so-called capability
LVC Allocator : Aligning training value with scenario design for envisioned LVC training of fast-jet pilots
Live virtual constructive (LVC) flight simulations mix pilots flying actual aircraft, pilots flying in simulators, and computer-generated forces, in joint scenarios. Training resources invested in LVC scenarios must give a high return, and therefore pilots in both live aircraft and simulators need to experience training value for the extensive resources invested in both, an aspect not emphasized i
Framing the FRAM: A literature review on the functional resonance analysis method
The development of the Functional Resonance Analysis Method (FRAM) has been motivated by the perceived limitations of fundamentally deterministic and probabilistic approaches to understand complex systems’ behaviour. Congruent with the principles of Resilience Engineering, over recent years the FRAM has been progressively developed in scientific terms, and increasingly adopted in industrial enviro

BioMEL : a translational research biobank of melanocytic lesions and melanoma
Introduction Diagnosing invasive cutaneous melanoma (CM) can be challenging due to subjectivity in distinguishing equivocal nevi, melanoma in situ and thin CMs. The underlying molecular mechanisms of progression from nevus to melanoma must be better understood. Identifying biomarkers for treatment response, diagnostics and prognostics is crucial. Using biomedical data from biobanks and population-
Rise and fall of the giants? : Innovating firms in Sweden, 1890-2016
This study investigates patterns of innovation during two successive industrial revolutions in Sweden. “Genius engineering firms”, such as L M Ericsson, SKF and ASEA (ABB) have dominated narratives about Sweden’s industrial and innovation success. Using new long-term data series of innovation output, 1890-2016, we observe several patterns. First, we document inverted U-shaped patterns during the c
Fundamental bounds on the performance of monochromatic passive cloaks
Fundamental bounds on the performance of monochromatic scattering-cancellation and field-zeroing cloaks made of prescribed linear passive materials occupying a predefined design region are formulated by projecting field quantities onto a sub-sectional basis and applying quadratically constrained quadratic programming. Formulations are numerically tested revealing key physical trends as well as adv
Train stations’ impact on housing prices : Direct and indirect effects
Investments in rail are usually expected to improve accessibility for individuals. The value of the additional accessibility is often measured by the impact on housing prices nearby. This paper analyses the City Tunnel in Southern Sweden, a major railway investment that resulted in two new train stations in 2010: the Triangeln and Hyllie train stations. A station may affect housing prices both dir
Integrating shared e-scooters as the feeder to public transit : A comparative analysis of 124 European cities
E-scooter sharing is a potential feeder to complement public transit for alleviating the first-and-last-mile problem. This study investigates the integration between shared e-scooters and public transit by conducting a comparative analysis in 124 European cities based on vehicle availability data. Results suggest that the integration ratios of e-scooter sharing in different cities show significant
To Deploy, or Not to Deploy, That is the Question A qualitative study of the decision-making experiences of engineers deploying software changes in production
The web services that millions of people count on require large-scale computer resources (servers, nodes, networking) and an intricate set of interdependent software services. Under pressure to continually improve these services, code and configuration changes are deployed hundreds or thousands of times every day. Unforeseen issues and vulnerabilities during the deployment process can lead to cost
Exploring unmanned systems with virtual prototypes in augmented reality video
The potential of unmanned systems is vast, but pre-procurement evaluation is challenging. This study explores potential uses of and interaction with unmanned ground vehicles (UGVs) for dismounted infantry. A remote user study with Swedish Armed Forces personnel is described. Many factors influencing future use and interaction were found. Moreover, this study shows the potential of the innovative m
A live mindset in Live Virtual Constructive simulations : a spin-up for future LVC air combat training
Combining Live, Virtual, and Constructive (LVC) aircraft in the same training scenario holds promise for developing and enhancing fighter pilot training. The simulator study reported here builds on joint pilot-researcher co-design work of beyond visual range LVC training (LVC-T) scenarios to provide training value to pilots in both Live and Virtual aircraft. One fourship of pilots simulated Live e
A method to identify investigative blind spots (MIBS) : Addressing blunt-end factors of ultra-safe organizations’ investigation-work-as-done
Ultra-safe organizations, such as Air Navigation Service Providers (ANSPs), have extensive safety management organizations and generally excellent safety records with very few serious incidents and accidents. This development has been supported by increasingly advanced and effective methods. However, recent research has uncovered how the application of even advanced incident investigation methods
Physical Bounds for Antennas Above a Ground Plane
Physical limitations of antennas above infinite perfect electric conductor (PEC) ground planes are determined using the stored electromagnetic energy. Stored energies are computed with the method of moments (MoM) and the image theory. Convex optimization is used to derive the G/Q ratio and Q-factor for a reference geometry, and the results are compared for different antenna types.
New Antidiabetic Agents for the Treatment of Heart Failure in Hypertensive Patients
The development of newer glucose-lowering drugs for the treatment of type 2 diabetes in recent years, such as the SGLT-2 inhibitors and GLP-1 receptor agonists/analogues with well-documented clinical benefits from large trials, has influenced international guidelines. These drugs are able to reduce both macro- and microvascular events in patients with type 2 diabetes and to prevent worsening of di
Optimal Planar Electric Dipole Antennas: Searching for antennas reaching the fundamental bounds on selected metrics
Considerable time is often spent optimizing antennas to meet specific design metrics. Rarely, however, are the resulting antenna designs compared to rigorous physical bounds on those metrics. Here, we study the performance of optimized planar meander line antennas with respect to such bounds. Results show that these simple structures meet the lower bound on the radiation quality factor (Q-factor)
A primordial tRNA modification required for the evolution of life?
The evolution of reading frame maintenance must have been an early event, and presumably preceded the emergence of the three domains Archaea, Bacteria and Eukarya. Features evolved early in reading frame maintenance may still exist in present-day organisms. We show that one such feature may be the modified nucleoside 1-methylguanosine (m(1)G37), which prevents frameshifting and is present adjacent
Polydopamine functionalized dendritic fibrous silica nanoparticles as a generic platform for nucleic acid-based biosensing
Accurate and rapid detection of nucleic acid sequences is of utmost importance in various fields, including disease monitoring, clinical treatment, gene analysis and drug discovery. In this study, we developed a "turn-on" fluorescence biosensor that enables simple and highly efficient detection of nucleic acid biomarkers. Our approach involves the utilization of 6-carboxyfluorescein modified singl
Operationalising resilience for disaster medicine practitioners: capability development through training, simulation and reflection
Resilience has in recent decades been introduced as a term describing a new perspective within the domains of disaster management and safety management. Several theoretical interpretations and definitions of the essence of resilience have been proposed, but less work has described how to operationalise resilience and implement the concept within organisations. This case study describes the impleme
