Forskningsöversikt (refereegranskat)abstract
- Surface electromyography (sEMG) has been the subject of thousands of scientific articles, but many barriers limit its clinical applications. Previous work has indicated that the lack of time, competence, training, and teaching is the main barrier to the clinical application of sEMG. This work follows up and presents a number of analogies, metaphors, and simulations using physical and mathematical models that provide tools for teaching sEMG detection by means of electrode pairs (1D signals) and electrode grids (2D and 3D signals). The basic mechanisms of sEMG generation are summarized and the features of the sensing system (electrode location, size, interelectrode distance, crosstalk, etc.) are illustrated (mostly by animations) with examples that teachers can use. The most common, as well as some potential, applications are illustrated in the areas of signal presentation, gait analysis, the optimal injection of botulinum toxin, neurorehabilitation, ergonomics, obstetrics, occupational medicine, and sport sciences. The work is primarily focused on correct sEMG detection and on crosstalk. Issues related to the clinical transfer of innovations are also discussed, as well as the need for training new clinical and/or technical operators in the field of sEMG.

An explicit solution of the (quantum) elliptic Calogero-Sutherland model
- 2005
-
Ingår i: SPT 2004. - : WORLD SCIENTIFIC. - 9812560912 ; , s. 159-174
-
Konferensbidrag (refereegranskat)abstract
- We present explicit formulas for the eigenvalues and eigenfunctions of the elliptic Calogero-Sutherland (eCS) model as formal power series to all orders in the nome of the elliptic functions, for arbitrary values of the (positive) coupling constant and particle number. Our solution gives explicit formulas for an elliptic deformation of the Jack polynomials.

Teachers participation in practice based research : a methodological retrospect
- 2021

Ingår i: Nordisk matematikkdidaktikk, NOMAD. - Göteborg : Nationellt centrum för matematikutbildning (NCM). - 1104-2176. ; 26:3-4, s. 113-130

Tidskriftsartikel (refereegranskat)abstract
- The focus of this article is methodological, on how teachers’ participation in practice-based research coacts with research quality. Educational design research is an example of a practice-based research approach often used in mathematics education with the goal of developing both the theories and the practice of teaching and learning mathematics. In this article, one such educational design research study on problem solving in Swedish preschool class is used as an example of how teachers’ participation in practice-based research can develop and of how different kinds of collaboration between researchers and teachers coact with research quality. One conclusion of the methodological meta-analysis is that there is a challenging tension between ensuring external validity of a study versus enabling internal validity and improvement of practice.

Zombies lost in translation. The translation from English to Spanish of (de)humanizing pronouns
- 2019
-
Ingår i: Revista de lingüística y lenguas aplicadas. - : Universitat Politecnica de Valencia. - 1886-2438 .- 1886-6298. ; 14, s. 91-103

Tidskriftsartikel (refereegranskat)abstract
- The present paper analyses which strategies are used in order to express the personal/inanimate pronoun contrast that serves the function of (de)humanizing zombies, when passages containing this linguistic feature in English are translated into Spanish. English has two sets of pronouns/adjectives, the ones that express personhood (he/his/him, she/her), and the inanimate ones (it/its). The explicit use of these pronouns is obligatory. Spanish on the other hand, has one set of pronouns (él, ella, su, lo, la) that are used both to express personhood as well as with inanimate references. The Spanish subject pronouns are normally used only when there is a need to highlight the subject or contrast it with another subject. Consequently, translators from English to Spanish face a challenge with regard to the translation of the (de)humanizing effect the pronoun contrast adds to the texts in English. The corpus contains examples of the English pronouns being translated with noun phrases, verb phrases, noun clauses, and pronouns, while in some cases the pronoun contrast is omitted, and therefore lost in the translation.

Successful tyrosine kinase inhibitor discontinuation outside clinical trials - data from the population-based Swedish chronic myeloid leukaemia registry

Tidskriftsartikel (refereegranskat)abstract
- Clinical trials show that tyrosine kinase inhibitor (TKI) treatment can be discontinued in selected patients with chronic myeloid leukaemia (CML). Although updated CML guidelines support such procedure in clinical routine, data on TKI stopping outside clinical trials are limited. In this retrospective study utilising the Swedish CML registry, we examined TKI discontinuation in a population-based setting. Out of 584 patients diagnosed with chronic-phase CML (CML-CP) in 2007-2012, 548 had evaluable information on TKI discontinuation. With a median follow-up of nine years from diagnosis, 128 (23%) discontinued TKI therapy (>= 1 month) due to achieving a DMR (deep molecular response) and 107 (20%) due to other causes (adverse events, allogeneic stem cell transplant, pregnancy, etc). Among those stopping in DMR, 49% re-initiated TKI treatment (median time to restart 4 center dot 8 months). In all, 38 patients stopped TKI within a clinical study and 90 outside a study. After 24 months 41 center dot 1% of patients discontinuing outside a study had re-initiated TKI treatment. TKI treatment duration pre-stop was longer and proportion treated with second-generation TKI slightly higher outside studies, conceivably affecting the clinical outcome. In summary we show that TKI discontinuation in CML in clinical practice is common and feasible and may be just as successful as when performed within a clinical trial.

Excessive behaviors in clinical practice - A state of the art article
- 2016

Ingår i: International Journal of Qualitative Studies on Health and Well-being. - : Informa UK Limited. - 1748-2623 .- 1748-2631. ; 11

Tidskriftsartikel (refereegranskat)abstract
- This paper concerns difficulties with excessive food intake, sexual activities, romantic relationships, gambling, Internet use, shopping, and exercise-behaviors that might cause considerable suffering. Excessive behaviors are seen as expressions of underlying difficulties that often co-occur with other psychological difficulties, and behaviors may accompany or replace each other. Moreover, they might pass unnoticed in clinical practice. Given the complexity of excessive behaviors, integrated and individualized treatment has been recommended. This paper presents an overview of the terminology concerning excessive behaviors, and the impact of naming is acknowledged. Thereafter, methods for identification and assessment, as well as treatment needs are discussed. Because identification, assessment, and treatment occur in an interaction between client and practitioner, this paper presents a discussion of the need to empower practitioners to identify and assess excessive behaviors and provide an integrated treatment. Moreover, the need to support practitioners' capacity to handle and tolerate the overwhelming suffering and the negative consequences connected to excessive behaviors is discussed. Qualitative studies are suggested in order to understand the meaning of excessive behaviors, treatment needs, and the interaction between client and practitioner.
