Journal article (peer-reviewed)abstract
- Background: The functional benefits of total wrist arthroplasty (TWA) over total wrist fusion (TWF) are unknown. The purpose of this prospective cohort study was to compare TWA and TWF with respect to functional outcomes and activitylimitations at up to 2 years postoperatively.Methods: Between 2015 and 2020, we enrolled all adult patients undergoing TWA or TWF for the management of symptomatic end-stage wrist arthritis at 1 hand surgery department. The primary outcome was the Patient-Rated Wrist Evaluation (PRWE). The secondary outcomes were the visual analog scale (VAS) for pain at rest, on motion, and on loading; grip strength; Disabilities of the Arm, Shoulder and Hand (DASH); and range of motion. Patients completed questionnairesand were examined by the same physiotherapist at baseline and at 3, 6, 12, and 24 months postoperatively. Mixed-model analyses adjusting for age, diagnosis, the preoperative value of the dependent variable, and time since surgery wereperformed to compare differences in PRWE scores, VAS pain scores, and grip strength between TWA and TWF.Results: Of the 51 patients who had been included at baseline, 47 (18 in the TWA group and 29 in the TWF group) responded to questionnaires and underwent examinations at up to 2 years postoperatively. At baseline, the 2 groups did not differ in terms of age, sex, diagnosis (inflammatory or noninflammatory arthritis), PRWE score, VAS pain score, grip strength, DASH score, or range of motion. No differences between the groups were found for the PRWE (b, 20.1; 95% confidence interval [CI], 214 to 13; p = 0.99), VAS pain at rest (b, 23.3; 95% CI, 215 to 9; p = 0.58), VAS pain on loading (b, 25.3; 95% CI, 222 to 11; p = 0.52), or grip strength (b, 20.02; 95% CI, 20.18 to 0.14; p = 0.80) on the adjusted mixed-model analyses.Conclusions: Among patients with symptomatic end-stage wrist arthritis, those who underwent TWA did not demonstrate short-term outcomes, including patient-reported disability, pain, and grip strength, superior to those of patients who underwent TWF. These findings call into question the widespread use of TWA.Level of Evidence: Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

RESISTIRÉ D6.4: Overall report on Solutions
- 2023
-
Reports (other academic/artistic)abstract
- This deliverable gives an overview of the different processes across all three cycles of the project that led to the development of RESISTIRÉ’s various outputs: the operational recommendations, the pilot projects, and the agendas for future research. The operational recommendations, designed as RESISTIRÉ factsheets, focused on 22 topics in total. For the pilot projects, seven different sets of terms of reference were developed over the first two cycles, eventually resulting in nine implemented pilot projects (two for Green Spaces as Ecosystems of Care and two for Engaging with Gender-based Violence Through Sports) across eight different countries. Finally, by the end of the third cycle, sixteen research agendas had been developed as well. Following the solutions created as part of the project, this report concludes with a section that indicates the various lessons that were learned throughout RESISTIRÉ’s three cycles. These lessons are differentiated by task, as the processes for developing the operational recommendations, pilot projects, and future research agendas all markedly differ from each other. They provide an insight into the strong points as well as the difficulties of the solution development processes.

Momentum selectivity and anisotropy effects in the nitrogen K -edge resonant inelastic x-ray scattering from GaN
- 2005
-
In: Physical Review B. Condensed Matter and Materials Physics. - 1098-0121 .- 1550-235X. ; 72:8

Journal article (peer-reviewed)abstract
- High-resolution soft x-ray emission and absorption spectra near the N K -edge of wurtzite GaN are presented. The experimental data are interpreted in terms of full-potential electronic structure calculations. The absorption spectra, compared with calculations including core hole screening, indicate partial core hole screening in the absorption process. The resonantly excited x-ray emission spectra show pronounced dispersion of spectral structures, which is attributed to effects of momentum conservation in the resonant inelastic x-ray scattering (RIXS) process. In development of GaN based optoelectronics, momentum selectivity in RIXS can be utilized to control development of band structure in GaN nanostructures. © 2005 The American Physical Society.

Softer, thinner and more complaint cochlear implants with liquid metal
- 2022
-
Conference paper (peer-reviewed)abstract
- A cochlear implant (CI) can restore sound perception for people with congenital or sensorineural hearing loss. Liquid metal (LM) based CI is more soft and complaint, enhancing its compliance and reducing intra-cochlear trauma, but the LM pattern demands high resolution. This work introduces a PCB manufacturing technique for high-resolution LM-based cochlear implant fabrication. It consists of laser cutting and ablation, masked LM microscale spray deposition, lift-off, and encapsulation. The microscale deposition is capable of patterning uniform LM at high resolution by fine spraying a sonication-produced LM particle based ink. A novel feature is that the laser-processable substrate is engraved when cutting the protective lift-off mask, avoiding mask transfer by lamination and allowing for alignment, vias, and higher aspect ratio structures, at high resolution. This feature simplifies the whole process and improves the precision and yield, allowing for more complex circuits. The fabricated CI shows good performance both in the inserting process and electrical signal.

Semiconductor-ionic Membrane of LaSrCoFe-oxide-doped Ceria Solid Oxide Fuel Cells
- 2017
-
In: Electrochimica Acta. - : Elsevier BV. - 0013-4686 .- 1873-3859. ; 248, s. 496-504
-
Journal article (peer-reviewed)abstract
- A novel semiconductor-ionic La0.6Sr0.4Co0.2Fe0.8O3-delta (LSCF)-Sm/Ca co-doped CeO2 (SCDC) nanocomposite has been developed as a membrane, which is sandwiched between two layers of Ni0.8Co0.15Al0.05Li-oxide (NCAL) to construct semiconductor-ion membrane fuel cell (SIMFC). Such a device presented an open circuit voltage (OCV) above 1.0 V and maximum power density of 814 mW cm(-2) at 550 degrees C, which is much higher than 0.84 V and 300 mW cm(-2) for the fuel cell using the SCDC membrane. Moreover, the SIMFC has a relatively promising long-term stability, the voltage can maintain at 0.966 V for 60 hours without degradation during the fuel cells operation and the open-circuit voltage (OCV) can return to 1.06 V after long-term fuel cell operation. The introduction of LSCF electronic conductor into the membrane did not cause any short circuit but brought significant enhancement of fuel cell performances. The Schottky junction is proposed to prevent the internal electrons passing thus avoiding the device short circuiting problem.

Digitaliseringspotential av programmeringskurser inom den högre utbildningen
- 2020
-
In: Journal of Teaching and Learning in Higher Education (JoTL). - : Malmö universitet. - 2004-4097. ; :2
-
Journal article (other academic/artistic)abstract
- För studenter inom IT-relaterade ämnen är programmering en grundläggande kunskap som borde utvecklas tidigt i deras utbildning. Det innebär inte bara lärandet av syntax och semantik av ett visst programmeringsspråk, men också att utveckla förmågan att kunna kombinera olika enskilda instruktioner till en algoritm eller ett dataprogram som kan lösa ett visst problem. Hittills genomfördes många programmeringskurser inom högre utbildning som campuskurser och skiftet till distansundervisning medförde behovet att identifiera nya lämpliga undervisningsformer.Syftet med den här artikeln är att analysera befintliga online-lärandemiljöer för att identifiera innovativa verktyg samt didaktiska angreppssätt som kan användas i distansundervisning av programmering inom högre utbildning. I artikeln presenteras det en diskussion av deras lämplighet för digitalisering av olika moment i programmeringskurser, ur både studentens och lärarens perspektiv, men också hur den konstruktiva länkningen med aktuella kursmål kan uppnås eller styrkas. Digitaliseringspotentialen visas genom exemplet av kursen DA343A (”Objektorienterad programutveckling, trådar och datakommunikation”) på Malmö universitet, som riktar sig till studenter i kandidatprogrammet i datavetenskap med inriktning systemutveckling och högskoleingenjörsutbildningen i datateknik.
