Forskningsöversikt (refereegranskat)abstract
- Digital anamorphosis is used to define a distorted image of health and care that may be viewed correctly using digital tools and strategies. MASK digital anamorphosis represents the process used by MASK to develop the digital transformation of health and care in rhinitis. It strengthens the ARIA change management strategy in the prevention and management of airway disease. The MASK strategy is based on validated digital tools. Using the MASK digital tool and the CARAT online enhanced clinical framework, solutions for practical steps of digital enhancement of care are proposed.

A sustainable trajectory for the 2030 Agenda: Targeting historical lock‐ins to accelerate progress on all SDGs
- 2024

Ingår i: Sustainable Development. - 0968-0802 .- 1099-1719.

Tidskriftsartikel (refereegranskat)abstract
- The 2030 Agenda states that the 17 sustainable development goals (SDGs) make parts of an indivisible whole, and research on SDG implementation highlights how managing goal interactions—synergies and trade-offs—is key for implementation to be successful. Here, we present an empirically based and transparent method for developing “consistent scenarios” that identifies which SDGs will be unattainable if historical patterns of interaction between SDGs are maintained. Using historical data on SDG indicators and correlation analysis together with cross-impact balance analysis, we identify such scenarios for a set of high- to low-income countries. Finding no consistent scenario where progress can be made on all 17 SDGs for any of the countries, our findings demonstrate the importance of policies that target interactions and resolve trade-offs rather than individual goals to unlock a sustainable future trajectory. This reflects what was novel about the SDGs as a framework for global development; that the goals are indivisible and achieving them all require systemic changes that alter how social and economic processes interact with the environment.

Quantal trajectories and geometric phase
- 1998
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis concerns the following topics: geometric phase in the context of Galilean invariance and quantum measurements, Rydberg states of hydrogen atoms, vibronic coupling in the E Ä e Jahn-Teller system and realism in quantum computations. In the analyses the de Broglie-Bohm pilot-wave formulation of quantummechanics is mainly used.It is shown that geometric phase is not Galilean invariant. Experimental implications are discussed and it is found that the experiments performed to date are frame independent. An experiment which is in principle able to detect the noninvariance is sketched. By adopting the measurement theory of the pilot-wave formulation it is shown how the measurement induced geometric phase continuously emerges. The Samuel-Bhandari geometric phase is identified as the nonrandom part of the total geometric phase induced in the measurement.Ensembles of particles for a circular Rydberg wave packet are studied. The trajectories of pilot-wave particles are shown to accurately imitate the behaviour of the wave packet in the high quantum number limit. The nonclassical features of the wave packet are intuitively explained by the nonvanishing quantum potential.Vibronic coupling in the Longuet-Higgins model of the E Ä e Jahn-Teller system is investigated by means of quantal trajectories. The pilot-wave picture provides an intuitive tool for discussing time-scales. An argument based on ergodicity leads to an understanding of the averaging procedure over the electronic motion which provides the approximate nuclear motion.The existence of efficient quantum algorithms triggers questions on Natures ability of storing and processing information during quantum computations. The role of elements of reality in quantum computations is addressed using quantal trajectories. It is found that there is a many-to-one relationship between quantal trajectories and performed computations when quantum parallelism is utilized.

Quantal trajectories for adiabatic and nonadiabatic regimes of vibronic systems
- 1999

Tidskriftsartikel (refereegranskat)abstract
- Exact and averaged nuclear pseudorotational quantal trajectories are compared for Various adiabatic and vibronic states of the Longuet-Higgins E x epsilon Jahn-Teller model. It is argued that the usual averaging over the electronic motion could be understood as being a consequence of ergodicity. The failure of the Born-Oppenheimer factorization to obey the ergodic hypothesis was examined. A quantitative separation of the electronic and nuclear time-scales is, nevertheless, achieved for all regimes. It is shown that the short-time deviations from the global "drift" of the electronic and nuclear motions are perfectly correlated.

Exercise induced breathing problems in adolescents
- 2015
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Experiencing respiratory symptoms in conjunction with exercise is common in children and adolescents and can have a negative impact on daily life. The aim of the thesis was to estimate the prevalence of exercise-induced dyspnoea, exercise-induced bronchoconstriction (EIB) and exercise-induced laryngeal obstruction (E-ILO) in a general adolescent population, and to explore factors associated with EIB.Methods: All 12-13-year-old adolescents in the city of Uppsala (n=3,838) participated in a survey on exercise-induced dyspnoea. A subsample of adolescents who answered the survey, 103 randomly selected adolescents reporting exercise-induced dyspnoea and 47 random adolescents who did not report exercise-induced dyspnoea underwent standardised treadmill exercise tests for EIB and E-ILO. The exercise test for EIB was performed while breathing dry air; a positive test was defined as a decrease ≥10% in FEV1 from baseline. E-ILO was investigated using continuous laryngoscopy during exercise. Health related quality of life (HRQoL), and objectively measured daily physical activity were investigated in those with (n=49) and without (n=91) a positive EIB-test.Results: The prevalence of exercise-induced dyspnoea was 14%, and the estimated prevalence of EIB and E-ILO in the total population was 19.2% and of 5.7%, respectively, with no gender differences. In adolescents with exercise-induced dyspnoea 40% had EIB, 6% had E-ILO, and 5% had both conditions.An increased baseline level of fraction of nitric oxide in exhaled air (FeNO), female gender, and exercise-induced dyspnoea were associated with a positive EIB test. Female adolescents with EIB had lower HRQoL and lower baseline lung function compared to females without EIB. These differences were not observed in male adolescents. There was no difference in time spent in moderate- to vigorous daily physical activity between adolescents with and without EIB.

Berry's phase in pilot-wave theory

Tidskriftsartikel (refereegranskat)abstract
- The projective-geometric derivation of Berry's adiabatic geometric phase for a single trajectory in the de Broglie-Bohm pilot-wave theory is given. The relation between this phase and the first order nature of pilot-wave theory is discussed. It is shown, in the case where the electromagnetic vector potential is a gradient, that the phase can be given in a locally phase invariant form. The appearance of the Berry connection is justified and its physical significance in pilot-wave theory is discussed.

Tidskriftsartikel (refereegranskat)abstract
- It is shown that generally geometric phase in nonrelativistic quantum mechanics is not Galilean invariant. It appears, however, that in none of the actual experiments performed to date on geometric phase is the measured phase frame dependent.

Tidskriftsartikel (refereegranskat)abstract
- An approach to the measurement induced geometric phase based on the de Broglie-Bohm hidden-variable model is developed. The analysis involves an evolving geometric phase connecting the initial and final states of an individual experimental run. As an illustration the geometric phase produced by a cyclic sequence of spin-1/2 filtering experiments is considered. It is argued, in this case, that the geometric phase can be made close to the Samuel-Bhandari phase.
