La discusión medieval sobre el significado primordial de la palabra : Medieval discussion on the primordial meaning of words
- 2016
-
In: deSignis. - 1578-4223 .- 2462-7259. ; 25, s. 77-88
-
Journal article (peer-reviewed)abstract
- In the fourteenth century, Duns Scotus tells us about a debate about the primor - dial significate of words – whether it is a thing or a concept. The present article shows that the origin of the debate can be traced back to the first half of the thirteenth century; that initially the debate involves problems of different nature; and that towards the end of the century some masters narrow the use of the notion of signification so as to leave it an explanatory role only in the semiotic domain.

A socio-institutional perspective on the reluctance among the elderly concerning the commercialization of 3D surgical video technology in Sweden
- 2023
-
In: Journal of Innovation and Knowledge. - : Elsevier. - 2530-7614 .- 2444-569X. ; 8:2
-
Journal article (peer-reviewed)abstract
- The pursuit of commercialization is at the core of economic activity, and limited commercialization success is generally ascribed to the lower scalability or potential of the venture. Drawing on the anti-profit-taking socio-institutional perspective and innovation resistance theory, commercialization of a value-creating technology could be resisted from the demand side. We use a 3D surgical video technology developed at a Swedish hospital along with Potentially All Pairwise RanKings of all possible alternatives (PAPRIKA) based on conjoint analysis completed by 1437 elderly individuals. We find that, despite the value benefits for the surgeon and the overall social benefits of the technology, the most preferred part-worth utility (i.e., weight) of relative importance is a preference for not commercializing the technology for profit. These findings carry implications for entrepreneurship and institutional theory related to medical innovations in countries with universal healthcare.

The wait time to primary surgery in endometrial cancer - impact on survival and predictive factors: a population-based SweGCG study
- 2022
-
In: Acta Oncologica. - : Informa UK Limited. - 0284-186X .- 1651-226X. ; 61:1, s. 30-37
-
Journal article (peer-reviewed)abstract
- Background Poor survival rates in different cancer types are sometimes blamed on diagnostic and treatment delays, and it has been suggested that such delays might be related to sociodemographic factors such as education and ethnicity. We examined associations of the wait time from diagnosis to surgery and survival in endometrial cancer (EC) and explored patient and tumour factors influencing the wait time. Material and methods In this historical population-based cohort study, The Swedish Quality Registry for Gynaecologic Cancer (SQRGC) was used to identify EC patients who underwent primary surgery between 2010 and 2018. Factors associated with a wait time > 32 d were analysed with logistic regression. The 32-d time point was defined in accordance with the Swedish Standardisation Cancer Care programme. Adjusted Poisson regression analyses were used to analyse excess mortality rate ratio (EMRR). Results Out of 7366 women, 5535 waited > 32 d for surgery and 1098 > 70 d. The overall median wait time was 44 d. The factors most strongly associated with a wait time > 32 d were surgery at a university hospital (adjusted odds ratio [OR] 1.34, 95% confidence interval [CI] 1.08-1.66) followed by country of birth (OR 1.31, 95% CI 1.10-1.55) and year of diagnosis. There were no associations between wait time and histology or age. A wait time < 15 d was associated with higher mortality (adjusted EMRR 2.29,95% CI 1.36-3.84) whereas no negative survival impact was seen with a wait time of 70 d. Age, tumour stage, histology and risk group were highly associated with survival, whereas education, country of origin and hospital level did not have any impact on survival. Conclusions Surgery within the first two weeks after EC diagnosis was associated with worsened survival. A prolonged wait time did not seem to have any significant adverse effect on prognosis.

Towards Enabling Exploration of Planetary Subterranean Environments using Unmanned Aerial Vehicles
- 2023
-
Licentiate thesis (other academic/artistic)abstract
- This thesis presents a novel navigation framework established to enable the exploration of planetary subterranean areas with Unmanned Aerial Vehicles (UAVs). The key contributions of this thesis work form a robot-safe rapid navigation framework that utilizes a novel bifurcating frontier-based exploration approach. UAVs (limited to quadrotors in this work) have superior navigation capabilities compared to ground robots in terms of 3D navigation as well as fast and versatile Traversability. Utilizing this advantage, this thesis investigates exploration and path-planning problems and presents novel mission behavior-oriented exploration strategies that are evaluated through either simulation with true physics and atmospheric models of planetary bodies or real-world deployment in subterranean areas. The work included in this thesis is focused on two main research directions. The first direction establishes a novel coaxial quadrotor design that can operate in the thin atmosphere of Mars and utilize the Mars Coaxial Quadrotor (MCQ) to develop an energy-efficient exploration algorithm that leads to autonomously map Martian underground lava channel through true atmospheric model-based simulations. While the second direction establishes a Rapid Exploration Framework (REF) for the real-world deployment for the exploration of GPS-denied underground environments with UAVs. The contributions in the two directions are merged to develop a field-hardened autonomous exploration pipeline for UAVs that focuses on maintaining the heading vector of the UAV towards the most unknown area ahead of the UAV. While also bifurcating the exploration problem in local and global exploration for rapid navigation towards the unknown areas in the field of view and quickly globally re-positioning to a partially explored area. For navigating to the exploration goal of the UAV, it utilizes an expendable grid-based risk-aware path planning framework (D$^{*}_{+}$) that explicitly models unknown areas as risk and plans paths in safe space and for local obstacle avoidance and control the framework utilizes Artificial Potential Fields (APF) and a nonlinear Model Predictive Control based reference tracking scheme.Based on the learnings from field experiments and limitations of state-of-the-art grid-based planning methods on large-scale maps, the final contribution of the thesis establishes a Grid + Graph oriented Traversability-aware exploration and planning framework. The graph-based exploration method proposed in this thesis utilizes geometric shapes to define local traversable paths for the UAV to navigate to the local exploration goal. While utilizing a traversable graph that incrementally plans paths to the edge vertex of sub-maps in the direction of the global re-position goal. The strategy is evaluated extensively in simulations in subterranean urban, tunnel, and cave environments while it is also tested in real-world deployment at test mines of EPIROC and LKAB in Sweden.

Assumption Monitoring Using Runtime Verification for UAV Temporal Task Plan Executions
- 2021
-
In: Proceedings / IEEE International Conference on Robotics and Automation. - : IEEE. - 1050-4729.
-
Conference paper (peer-reviewed)abstract
- Temporal task planning guarantees a robot will succeed in its task as long as certain explicit and implicit assumptions about the robot’s operating environment, sensors, and capabilities hold. A robot executing a plan can silently fail to fulfill the task if the assumptions are violated at runtime. Monitoring assumption violations at runtime can flag silent failures and also provide mitigation and remediation opportunities. However, this requires means for describing assumptions combining temporal and quantitative data, automatic construction of correct monitors and ensuring a correct interplay between the planning execution and monitors. In this paper we propose combining temporal planning with stream runtime verification, which offers a high-level language to describe monitors together with guarantees on execution time and memory usage. We demonstrate our approach both in real and simulated flights for some typical mission scenarios.
