I hear what you see: Effects of audio description used in a cinema on immersion and enjoyment in blind and visually impaired people

Hättich, Achim ; Schweizer, Martina

In: British Journal of Visual Impairment, 2020, vol. 38, no. 3, p. 284–298

For people with disabilities being part of social life is essential for well-being. To accomplish this there are two possibilities: through interaction in person and through access to culture. One way to enjoy both possibilities is the cinema. For people with sight loss (people that are blind or visually impaired), there exists audio description which allows enjoying a film in a cinema....

Predicting failures in complex multi-tier systems

Xin, Rui ; Pezzè, Mauro (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020INFO017.

Complex multi-tier systems are composed of many distributed machines, feature multi-layer architecture and offer different types of services. Shared complex multi-tier systems, such as cloud systems, reduce costs and improves resource utilization efficiency, with a considerable amount of complexity and dynamics that challenge the reliability of the system. The new challenges of complex...

Less is more : efficient hardware design through Approximate Logic Synthesis

Scarabottolo, Ilaria ; Pozzi, Laura (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020INFO023.

As energy efficiency becomes a crucial concern in almost every kind of digital application, Approximate Computing gains popularity as a potential answer to this ever-growing energy quest. Approximate Computing is a design paradigm particularly suited for error- resilient applications, where small losses in accuracy do not represent a significant reduction in the quality of the result. In these...

Evaluating the effects of faculty development: theoretical framework and empirical implementation

Charlier, Bernadette ; Lambert, Marie

In: International Journal for Academic Development, 2019, vol. 25, no. 2, p. 162-175

This article implements a systemic evaluation framework to evaluate the long- term effects of a specific program characterized by a SoTL approach and a hybrid learning environment. The importance of the difference between the perception of long-term effects on individual professional development and the development of collective practices is interpreted by certain shortcomings of the FD...

Neuralink and Beyond: Challenges of Creating an Enhanced Human

Gurtner, Dimitri

(Internal working papers DIUF ; 21-01)

This article is a literature review of Neuralink, brain-machine interfaces (BMIs) and their applications, followed by future possibilities of BMIs and their potential impacts. Currently, BMIs predominantly have therapeutic applications, such as helping people with spinal cord injury by allowing them to control a computer directly with their brain. However, BMIs can also improve learning,...

Aerobically stable and substitutionally labile α-diimine rhenium dicarbonyl complexes

Schindler, Kevin ; Crochet, Aurélien ; Zobi, Fabio

In: RSC Advances, 2021, vol. 11, p. 7511-7520

New synthetic routes to aerobically stable and substitutionally labile α-diimine rhenium(I) dicarbonyl complexes are described. The molecules are prepared in high yield from the cis–cis–trans-[Re(CO)2(tBu2bpy)Br2]− anion (2, where tBu2bpy is 4,4′- di-tert-butyl-2,2′-bipyridine), which can be isolated from the one electron reduction of the corresponding 17-electron complex (1)....

Infrared study of the multiband low-energy excitations of the topological antiferromagnet MnBi2Te4

Xu, Bing ; Zhang, Y. ; Alizade, E. H. ; Jahangirli, Z. A. ; Lyzwa, Fryderyk ; Sheveleva, Evgeniia ; Marsik, Premysl ; Li, Y. K. ; Yao, Y. G. ; Wang, Z. W. ; Shen, B. ; Dai, Y. M. ; Kataev, V. ; Otrokov, M. M. ; Chulkov, E. V. ; Mamedov, N. T. ; Bernhard, Christian

In: Physical Review B, 2021, vol. 103, no. 12, p. L121103

With infrared spectroscopy, we studied the bulk electronic properties of the topological antiferromagnet MnBi2Te4 with TN ≃ 25 K. With the support of band-structure calculations, we assign the intra- and interband excitations and determine the band gap of Eg ≈ 0.17 eV. We also obtain evidence for two types of conduction bands with light and very heavy carriers. The multiband free-carrier...

Muon spin rotation and infrared spectroscopy study of Ba$_{1-x}$Na$_{x}$Fe$_{2}$As$_{2}$

Sheveleva, Evgeniia ; Xu, Bing ; Marsik, Premysl ; Lyzwa, Fryderyk ; Mallett, Benjamin P. P. ; Willa, K. ; Meingast, C. ; Wolf, Th. ; Shevtsova, T. ; Pashkevich, Yu. G. ; Bernhard, Christian

In: Physical Review B, 2020, vol. 101, no. 22, p. 224515

The magnetic and superconducting properties of a series of underdoped Ba 1 − x Na x Fe 2 As 2 (BNFA) single crystals with 0.19 ≤ x ≤ 0.34 have been investigated with the complementary muon-spin-rotation ( μ SR ) and infrared spectroscopy techniques. The focus has been on the different antiferromagnetic states in the underdoped regime and their competition with superconductivity,...

The patent buyout price for human papilloma virus (HPV) vaccine and the ratio of R&D costs to the patent value

Songane, Mario ; Grossmann, Volker

In: PLOS One, 2021, p. 1-22

Human papillomavirus (HPV) is responsible for almost all of the 570,000 new cases of cervical cancer and approximately 311,000 deaths per year. HPV vaccination is an integral component of the World Health Organization’s (WHO) global strategy to fight the disease. However, high vaccine prices enforced through patent protection are limiting vaccine expansion, particularly in low- and...
